China. 2 STOBAR carriers: 1 CATOBAR carrier: 3 LHD amphibious assault ships China has had a long-term plan to operate six large aircraft carriers with two carriers per fleet. China is planning a class of eight LHD vessels, the Type 075 (NATO reporting name Yushen-class landing helicopter assault). This is a class of amphibious assault ship under construction by the Hudong–Zhonghua Shipbuilding company. The first ship was commissioned in April 2021. China is also planning a modified class of the same concept, the Type 076 landing helicopter dock, that will be equipped with an electromagnetic catapult system and will likely support launching unmanned combat aerial vehicles. Egypt. Egypt signed a contract with French shipbuilder DCNS to buy two helicopter carriers for approximately 950 million euros. The two ships were originally to be sold to Russia, but the deal was cancelled by France due to the Russian invasion of Ukraine in 2014. On 2 June 2016, Egypt received the first of two helicopter carriers acquired in October 2015, the landing helicopter dock . The flag transfer ceremony took place in the presence of Egyptian and French Navies' chiefs of staff, chairman and chief executive officers of both DCNS and STX France, and senior Egyptian and French officials. On 16 September 2016, DCNS delivered the second of two helicopter carriers, the landing helicopter dock which also participated in a joint military exercise with the French Navy before arriving at her home port of Alexandria.
France. The French Navy operates the 42,000-tonne nuclear-powered aircraft carrier, . Commissioned in 2001, she is the flagship of the French Navy. The ship carries a complement of Dassault Rafale M and E-2C Hawkeye aircraft, EC725 Caracal and AS532 Cougar helicopters for combat search and rescue, as well as modern electronics and Aster missiles. She is a CATOBAR-type carrier that uses two 75 m C13-3 steam catapults of a shorter version of the catapult system installed on the US carriers, one catapult at the bow and one across the front of the landing area. In addition, the French Navy operates three s. In October 2018, the French Ministry of Defence began an 18-month €40 million study for the replacement of the sometime after 2030. In December 2020, President Macron announced that construction of the next generation carrier would begin in around 2025 with sea trials to start in about 2036. The carrier is planned to have a displacement of around 75,000 tons and to carry about 32 next-generation fighters, two to three E-2D Advanced Hawkeyes and a yet-to-be-determined number of unmanned carrier air vehicles.
India. 2 STOBAR carriers: , 45,400 tonnes, modified "Kiev" class. The carrier was purchased by India on 20 January 2004 after years of negotiations at a final price of $2.35 billion (). The ship successfully completed her sea trials in July 2013 and aviation trials in September 2013. She was formally commissioned on 16 November 2013 at a ceremony held at Severodvinsk, Russia. , also known as "Indigenous Aircraft Carrier 1 (IAC-1)" a 45,000-tonne, aircraft carrier whose keel was laid in 2009. The new carrier will operate MiG-29K and naval HAL Tejas aircraft. The ship is powered by gas-turbines and has a range of and deploys 10 helicopters and 30 aircraft. The ship was launched in 2013, sea-trials began in August 2021 and was commissioned on 2 September 2022. India has plans for a third carrier, , also known as "Indigenous Aircraft Carrier 2 (IAC-2)" with a displacement of over 65,000 tonnes and is planned with a CATOBAR system to launch and recover heavier aircraft. India has also issued a request for information (RFI) to procure four Landing helicopter dock displacing 30,000–40,000 tons with a capacity to operate 12 medium lift special ops and two heavy lift helicopters and troops for amphibious operations.
Italy. 1 STOVL carrier: Italy plans to replace the now decommissioned aircraft carrier "Giuseppe Garibaldi", as well as one of the landing helicopter docks, with a new amphibious assault ship, to be named . The ship will be significantly larger than her predecessors with a displacement of 38,000 tonnes at full load. "Trieste" is to carry the F-35B Joint Strike Fighter. Meanwhile, "Giuseppe Garibaldi" will be transferred to Italian Space Operation Command for use as a satellite launch platform. Iran. IRIS Shahid Bagheri is a drone carrier. She was built in two years and is equipped with a drone fueling station, a floatplane and a helicopter, short and medium-range air defense systems, intelligence equipment, and a flight control tower. Other features include the ability to carry and use various types of drones, guided subsurfaces, the ability to identify various types of electronic signals - electronic warfare - full signet, long-range surface-to-surface cannons and weapons, long-range surface-to-surface cruise missiles, the ability to deal with various types of small aircraft and air defense missiles, and is equipped with a runway 180 meters long. Its main drone is IAIO Qaher-313.
Japan. In December 2018, the Japanese Cabinet gave approval to convert both "Izumo-class" destroyers into aircraft carriers for F-35B STOVL operations. The conversion of "Izumo" was underway as of mid-2020. The modification of maritime escort vessels is to "increase operational flexibility" and enhance Pacific air defense, the Japanese defense ministry's position is "We are not creating carrier air wings or carrier air squadrons" similar to the US Navy. The Japanese STOVL F-35s, when delivered, will be operated by the Japan Air Self Defense Force from land bases; according to the 2020 Japanese Defense Ministry white paper the STOVL model was chosen for the JASDF due the lack of appropriately long runways to support air superiority capability across all of Japanese airspace. Japan has requested that the USMC deploy STOVL F-35s and crews aboard the "Izumo-class" ships "for cooperation and advice on how to operate the fighter on the deck of the modified ships". On 3 October 2021, two USMC F-35Bs performed the first vertical landings and horizontal take-offs from JS "Izumo", marking 75 years since fixed-wing aircraft operated from a Japanese carrier.
Russia. 1 STOBAR carrier: "Admiral Flota Sovetskogo Soyuza Kuznetsov": 55,000-tonne STOBAR aircraft carrier. Launched in 1985 as "Tbilisi", renamed and operational from 1995. Without catapults she can launch and recover lightly fueled naval fighters for air defense or anti-ship missions but not heavy conventional bombing strikes. Officially designated an aircraft carrying cruiser, she is unique in carrying a heavy cruiser's complement of defensive weapons and large P-700 Granit offensive missiles. The P-700 systems will be removed in the coming refit to enlarge her below decks aviation facilities as well as upgrading her defensive systems. The ship has been out of service and in repairs since 2018. The current projection is that repairs will be completed and the ship will be transferred back to the Russian Navy sometime in 2024, however this may be pushed back to 2025 if issues arise during overhaul and testing. The Russian government has been considering the potential replacement of "Admiral Kuznetsov" for some time and has considered the Shtorm-class aircraft carrier as a possible option. This carrier will be a hybrid of CATOBAR and STOBAR, given the fact that she uses both systems of launching aircraft. The carrier is expected to cost As of 2020, the project had not yet been approved and, given the financial costs, it was unclear whether it would be made a priority over other elements of Russian naval modernization.
A class of 2 LHD, Project 23900 is planned and an official keel laying ceremony for the project happened on 20 July 2020. South Korea. Two 18,860-tonne full deck amphibious assault ships with hospital and well deck and facilities to serve as fleet flagships. South Korea has set tentative plans for procuring two light aircraft carriers by 2033, which would help make the ROKN a blue water navy. In December 2020, details of South Korea's planned carrier program (CVX) were finalized. A vessel of about 40,000 tons is envisaged carrying about 20 F-35B fighters as well as future maritime attack helicopters. Service entry had been anticipated in the early 2030s. The program has encountered opposition in the National Assembly. In November 2021, the National Defense Committee of the National Assembly reduced the program's requested budget of 7.2 billion KRW and to just 500 million KRW (about $400K USD), effectively putting the project on hold, at least temporarily. However, on 3 December 2021 the full budget of 7.2 billion won was passed by the National Assembly. Basic design work is to begin in earnest starting 2022.
Thailand. 1 offshore helicopter support ship: helicopter carrier: 11,400-tonne STOVL carrier based on Spanish design. Commissioned in 1997. The AV-8S Matador/Harrier STOVL fighter wing, mostly inoperable by 1999, was retired from service without replacement in 2006. As of 2010, the ship is used for helicopter operations and for disaster relief. Turkey. is a 27,079-tonne amphibious assault ship (LHD) (outfitted as drone carrier) of the Turkish Navy that can be configured as a 24,660-tonne V/STOL aircraft carrier. Construction began on 30 April 2016 by Sedef Shipbuilding Inc. at their Istanbul shipyard. TCG "Anadolu" was commissioned with a ceremony on 10 April 2023. The construction of a sister ship, to be named TCG "Trakya", is currently being planned by the Turkish Navy. The Sikorsky S-70B Seahawk and the Bell AH-1 SuperCobra are the two main types of helicopters used on TCG "Anadolu", with the occasional use of CH-47F Chinook helicopters of the Turkish Army during military exercises and operations. The AH-1W Super Cobras will eventually be complemented and replaced by the TAI T929 ATAK 2.
The jet-powered, low-observable drone Bayraktar MIUS Kızılelma and the MALE UAV Bayraktar TB3 are two UCAVs that are specifically designed and manufactured by Baykar Technologies to be used on TCG "Anadolu". The maiden flight of TAI Anka-3 (also part of Project MIUS), a jet-powered, flying wing type UCAV with stealth technology, was successfully completed on 28 December 2023. On 19 November 2024, Baykar Bayraktar TB3 UCAV successfully took-off from the flight deck of TCG "Anadolu" and landed on the ship. It was the first time a fixed-wing unmanned aircraft of this size and class had successfully landed on a short-runway landing helicopter dock, without the use of an arresting gear. On 3 January 2024, the Turkish government approved the plan for the design and construction of a larger aircraft carrier, named the "MUGEM"-class. On 15 February 2024, the Design and Projects Office of the Turkish Navy announced that it will be a STOBAR aircraft carrier with an overall length of , beam of , draught of , and displacement of 60,000 tons. It is to have a COGAG propulsion system and a maximum speed of more than .
The construction of the first "MUGEM"-class aircraft carrier began on 2 January 2025. The first "MUGEM"-class aircraft carrier is being built at the Istanbul Naval Shipyard. United Kingdom. Two 80,600-tonne (est. full load) "Queen Elizabeth"-class STOVL carriers which operate the F-35 Lightning II. was commissioned in December 2017 and in December 2019. "Queen Elizabeth" undertook her first operational deployment in 2021. Each "Queen Elizabeth"-class ship is able to operate around 40 aircraft during peacetime operations and is thought to be able to carry up to 72 at maximum capacity. As of the end of April 2020, 18 F-35B aircraft had been delivered to the Royal Navy and the Royal Air Force. "Full operating capability" for the UK's carrier strike capability had been planned for 2023 (two squadrons or 24 jets operating from one carrier). The longer-term aim remains for the ability to conduct a wide range of air operations and support amphibious operations worldwide from both carriers by 2026. They form the central part of the UK Carrier Strike Group.
The "Queen Elizabeth"-class ships are expected to have service lives of 50 years. United States. 11 CATOBAR carriers, all nuclear-powered: Nine amphibious assault ships carrying vehicles, Marine fighters, attack and transport helicopters, and landing craft with STOVL fighters for Close Air Support (CAS) and Combat Air Patrol (CAP): The current US fleet of "Nimitz"-class carriers will be followed into service (and in some cases replaced) by the . It is expected that the ships will be more automated in an effort to reduce the amount of funding required to maintain and operate the vessels. The main new features are implementation of Electromagnetic Aircraft Launch System (EMALS) (which replaces the old steam catapults) and unmanned aerial vehicles. In terms of future carrier developments, Congress has discussed the possibility of accelerating the phasing-out of one or more "Nimitz"-class carriers, postponing or canceling the procurement of CVN-81 and CVN-82, or modifying the purchase contract. Following the deactivation of in December 2012, the US fleet comprised 10 fleet carriers, but that number increased back to 11 with the commissioning of "Gerald R. Ford" in July 2017. The House Armed Services Seapower subcommittee on 24 July 2007, recommended seven or eight new carriers (one every four years). However, the debate has deepened over budgeting for the $12–14.5 billion (plus $12 billion for development and research) for the 100,000-tonne "Gerald R. Ford"-class carrier (estimated service 2017) compared to the smaller $2 billion 45,000-tonne s, which are able to deploy squadrons of F-35Bs. The first of this class, , is now in active service with another, , and 9 more are planned. In a report to Congress in February 2018, the Navy stated it intends to maintain a "12 CVN force" as part of its 30-year acquisition plan. Aircraft carriers in preservation. Current museum carriers. A few aircraft carriers have been preserved as museum ships. They are:
Apicomplexa The Apicomplexa (also called Apicomplexia; single: apicomplexan) are organisms of a large phylum of mainly parasitic alveolates. Most possess a unique form of organelle structure that comprises a type of non-photosynthetic plastid called an apicoplastwith an apical complex membrane. The organelle's apical shape is an adaptation that the apicomplexan applies in penetrating a host cell. The Apicomplexa are unicellular and spore-forming. Most are obligate endoparasites of animals, except "Nephromyces", a symbiont in marine animals, originally classified as a chytrid fungus, and the Chromerida, some of which are photosynthetic partners of corals. Motile structures such as flagella or pseudopods are present only in certain gamete stages. The Apicomplexa are a diverse group that includes organisms such as the coccidia, gregarines, piroplasms, haemogregarines, and plasmodia. Diseases caused by Apicomplexa include: The name Apicomplexa derives from two Latin words—"apex" (top) and "complexus" (infolds)—for the set of organelles in the sporozoite. The Apicomplexa comprise the bulk of what used to be called the Sporozoa, a group of parasitic protozoans, in general without flagella, cilia, or pseudopods. Most of the Apicomplexa are motile, however, with a gliding mechanism that uses adhesions and small static myosin motors. The other main lines of this obsolete grouping were the Ascetosporea (a group of Rhizaria), the Myxozoa (highly derived cnidarian animals), and the Microsporidia (derived from fungi). Sometimes, the name Sporozoa is taken as a synonym for the Apicomplexa, or occasionally as a subset.
Description. The phylum Apicomplexa contains all eukaryotes with a group of structures and organelles collectively termed the apical complex. This complex consists of structural components and secretory organelles required for invasion of host cells during the parasitic stages of the Apicomplexan life cycle. Apicomplexa have complex life cycles, involving several stages and typically undergoing both asexual and sexual replication. All Apicomplexa are obligate parasites for some portion of their life cycle, with some parasitizing two separate hosts for their asexual and sexual stages. Besides the conserved apical complex, Apicomplexa are morphologically diverse. Different organisms within Apicomplexa, as well as different life stages for a given apicomplexan, can vary substantially in size, shape, and subcellular structure. Like other eukaryotes, Apicomplexa have a nucleus, endoplasmic reticulum and Golgi complex. Apicomplexa generally have a single mitochondrion, as well as another endosymbiont-derived organelle called the apicoplast which maintains a separate 35 kilobase circular genome (with the exception of "Cryptosporidium" species and "Gregarina niphandrodes" which lack an apicoplast).
All members of this phylum have an infectious stage—the sporozoite—which possesses three distinct structures in an apical complex. The apical complex consists of a set of spirally arranged microtubules (the conoid), a secretory body (the rhoptry) and one or more polar rings. Additional slender electron-dense secretory bodies (micronemes) surrounded by one or two polar rings may also be present. This structure gives the phylum its name. A further group of spherical organelles is distributed throughout the cell rather than being localized at the apical complex and are known as the dense granules. These typically have a mean diameter around 0.7 μm. Secretion of the dense-granule content takes place after parasite invasion and localization within the parasitophorous vacuole and persists for several minutes. Replication: Mobility: Apicomplexans have a unique gliding capability which enables them to cross through tissues and enter and leave their host cells. This gliding ability is made possible by the use of adhesions and small static myosin motors.
Other features common to this phylum are a lack of cilia, sexual reproduction, use of micropores for feeding, and the production of oocysts containing sporozoites as the infective form. Transposons appear to be rare in this phylum, but have been identified in the genera "Ascogregarina" and "Eimeria". Life cycle. Most members have a complex lifecycle, involving both asexual and sexual reproduction. Typically, a host is infected via an active invasion by the parasites (similar to entosis), which divide to produce sporozoites that enter its cells. Eventually, the cells burst, releasing merozoites, which infect new cells. This may occur several times, until gamonts are produced, forming gametes that fuse to create new cysts. Many variations occur on this basic pattern, however, and many Apicomplexa have more than one host. The apical complex includes vesicles called rhoptries and micronemes, which open at the anterior of the cell. These secrete enzymes that allow the parasite to enter other cells. The tip is surrounded by a band of microtubules, called the polar ring, and among the Conoidasida is also a funnel of tubulin proteins called the conoid. Over the rest of the cell, except for a diminished mouth called the micropore, the membrane is supported by vesicles called alveoli, forming a semirigid pellicle.
The presence of alveoli and other traits place the Apicomplexa among a group called the alveolates. Several related flagellates, such as "Perkinsus" and "Colpodella", have structures similar to the polar ring and were formerly included here, but most appear to be closer relatives of the dinoflagellates. They are probably similar to the common ancestor of the two groups. Another similarity is that many apicomplexan cells contain a single plastid, called the apicoplast, surrounded by either three or four membranes. Its functions are thought to include tasks such as lipid and heme biosynthesis, and it appears to be necessary for survival. In general, plastids are considered to have a common origin with the chloroplasts of dinoflagellates, and evidence points to an origin from red algae rather than green. Subgroups. Within this phylum are four groups — coccidians, gregarines, haemosporidians (or haematozoans, including in addition piroplasms), and marosporidians. The coccidians and haematozoans appear to be relatively closely related.
"Perkinsus ", while once considered a member of the Apicomplexa, has been moved to a new phylum — Perkinsozoa. Gregarines. The gregarines are generally parasites of annelids, arthropods, and molluscs. They are often found in the guts of their hosts, but may invade the other tissues. In the typical gregarine lifecycle, a trophozoite develops within a host cell into a schizont. This then divides into a number of merozoites by schizogony. The merozoites are released by lysing the host cell, which in turn invade other cells. At some point in the apicomplexan lifecycle, gametocytes are formed. These are released by lysis of the host cells, which group together. Each gametocyte forms multiple gametes. The gametes fuse with another to form oocysts. The oocysts leave the host to be taken up by a new host. Coccidians. In general, coccidians are parasites of vertebrates. Like gregarines, they are commonly parasites of the epithelial cells of the gut, but may infect other tissues. The coccidian lifecycle involves merogony, gametogony, and sporogony. While similar to that of the gregarines it differs in zygote formation. Some trophozoites enlarge and become macrogamete, whereas others divide repeatedly to form microgametes (anisogamy). The microgametes are motile and must reach the macrogamete to fertilize it. The fertilized macrogamete forms a zygote that in its turn forms an oocyst that is normally released from the body. Syzygy, when it occurs, involves markedly anisogamous gametes. The lifecycle is typically haploid, with the only diploid stage occurring in the zygote, which is normally short-lived.
The main difference between the coccidians and the gregarines is in the gamonts. In the coccidia, these are small, intracellular, and without epimerites or mucrons. In the gregarines, these are large, extracellular, and possess epimerites or mucrons. A second difference between the coccidia and the gregarines also lies in the gamonts. In the coccidians, a single gamont becomes a macrogametocyte, whereas in the gregarines, the gamonts give rise to multiple gametocytes. Haemosporidia. The Haemosporidia have more complex lifecycles that alternate between an arthropod and a vertebrate host. The trophozoite parasitises erythrocytes or other tissues in the vertebrate host. Microgametes and macrogametes are always found in the blood. The gametes are taken up by the insect vector during a blood meal. The microgametes migrate within the gut of the insect vector and fuse with the macrogametes. The fertilized macrogamete now becomes an ookinete, which penetrates the body of the vector. The ookinete then transforms into an oocyst and divides initially by meiosis and then by mitosis (haplontic lifecycle) to give rise to the sporozoites. The sporozoites escape from the oocyst and migrate within the body of the vector to the salivary glands where they are injected into the new vertebrate host when the insect vector feeds again.
Marosporida. The class Marosporida is a newly recognized lineage of apicomplexans that is sister to the Coccidia and Hematozoa. It is defined as a phylogenetic clade containing "Aggregata octopiana" , "Merocystis kathae" (both Aggregatidae, originally coccidians), "Rhytidocystis" sp. 1 and "Rhytidocystis" sp. 2 (Rhytidocystidae , originally coccidians, Agamococcidiorida), and "Margolisiella islandica" (closely related to Rhytidocystidae). Marosporida infect marine invertebrates. Members of this clade retain plastid genomes and the canonical apicomplexan plastid metabolism. However, marosporidians have the most reduced apicoplast genomes sequenced to date, lack canonical plastidial RNA polymerase and so provide new insights into reductive organelle evolution. Ecology and distribution.
Many Coccidiomorpha have an intermediate host, as well as a primary host, and the evolution of hosts proceeded in different ways and at different times in these groups. For some coccidiomorphs, the original host has become the intermediate host, whereas in others it has become the definitive host. In the genera "Aggregata", "Atoxoplasma", "Cystoisospora", "Schellackia", and "Toxoplasma", the original is now definitive, whereas in "Akiba", "Babesiosoma", "Babesia", "Haemogregarina", "Haemoproteus", "Hepatozoon", "Karyolysus", "Leucocytozoon", "Plasmodium", "Sarcocystis", and "Theileria", the original hosts are now intermediate. Similar strategies to increase the likelihood of transmission have evolved in multiple genera. Polyenergid oocysts and tissue cysts are found in representatives of the orders Protococcidiorida and Eimeriida. Hypnozoites are found in "Karyolysus lacerate" and most species of "Plasmodium"; transovarial transmission of parasites occurs in lifecycles of "Karyolysus" and "Babesia". Horizontal gene transfer appears to have occurred early on in this phylum's evolution with the transfer of a histone H4 lysine 20 (H4K20) modifier, KMT5A (Set8), from an animal host to the ancestor of apicomplexans. A second gene—H3K36 methyltransferase (Ashr3 in plants)—may have also been horizontally transferred.
Blood-borne genera. Within the Apicomplexa are three suborders of parasites: Within the Adelorina are species that infect invertebrates and others that infect vertebrates. The Eimeriorina—the largest suborder in this phylum—the lifecycle involves both sexual and asexual stages. The asexual stages reproduce by schizogony. The male gametocyte produces a large number of gametes and the zygote gives rise to an oocyst, which is the infective stage. The majority are monoxenous (infect one host only), but a few are heteroxenous (lifecycle involves two or more hosts). The number of families in this later suborder is debated, with the number of families being between one and 20 depending on the authority and the number of genera being between 19 and 25. Taxonomy. History. The first Apicomplexa protozoan was seen by Antonie van Leeuwenhoek, who in 1674 saw probably oocysts of "Eimeria stiedae" in the gall bladder of a rabbit. The first species of the phylum to be described, "Gregarina ovata", in earwigs' intestines, was named by Dufour in 1828. He thought that they were a peculiar group related to the trematodes, at that time included in Vermes. Since then, many more have been identified and named. During 1826–1850, 41 species and six genera of Apicomplexa were named. In 1951–1975, 1873 new species and 83 new genera were added.
The older taxon Sporozoa, included in Protozoa, was created by Leuckart in 1879 and adopted by Bütschli in 1880. Through history, it grouped with the current Apicomplexa many unrelated groups. For example, Kudo (1954) included in the Sporozoa species of the Ascetosporea (Rhizaria), Microsporidia (Fungi), Myxozoa (Animalia), and "Helicosporidium" (Chlorophyta), while Zierdt (1978) included the genus "Blastocystis" (Stramenopiles). "Dermocystidium" was also thought to be sporozoan. Not all of these groups had spores, but all were parasitic. However, other parasitic or symbiotic unicellular organisms were included too in protozoan groups outside Sporozoa (Flagellata, Ciliophora and Sarcodina), if they had flagella (e.g., many Kinetoplastida, Retortamonadida, Diplomonadida, Trichomonadida, Hypermastigida), cilia (e.g., "Balantidium") or pseudopods (e.g., "Entamoeba, Acanthamoeba, Naegleria"). If they had cell walls, they also could be included in plant kingdom between bacteria or yeasts. Sporozoa is no longer regarded as biologically valid and its use is discouraged, although some authors still use it as a synonym for the Apicomplexa. More recently, other groups were excluded from Apicomplexa, e.g., "Perkinsus" and "Colpodella" (now in Protalveolata).
The field of classifying Apicomplexa is in flux and classification has changed throughout the years since it was formally named in 1970. By 1987, a comprehensive survey of the phylum was completed: in all, 4516 species and 339 genera had been named. They consisted of: Although considerable revision of this phylum has been done (the order Haemosporidia now has 17 genera rather than 9), these numbers are probably still approximately correct. Jacques Euzéby (1988). Jacques Euzéby in 1988 created a new class Haemosporidiasina by merging subclass Piroplasmasina and suborder Haemospororina. The division into Achromatorida and Chromatorida, although proposed on morphological grounds, may have a biological basis, as the ability to store haemozoin appears to have evolved only once. Roberts and Janovy (1996). Roberts and Janovy in 1996 divided the phylum into the following subclasses and suborders (omitting classes and orders): These form the following five taxonomic groups: Perkins (2000). Perkins et al. proposed the following scheme. It is outdated as the Perkinsidae have since been recognised as a sister group to the dinoflagellates rather that the Apicomplexia:
The name Protospiromonadida has been proposed for the common ancestor of the Gregarinomorpha and Coccidiomorpha. Another group of organisms that belong in this taxon are the corallicolids. These are found in coral reef gastric cavities. Their relationship to the others in this phylum has yet to be established. Another genus has been identified - "Nephromyces" - which appears to be a sister taxon to the Hematozoa. This genus is found in the renal sac of molgulid ascidian tunicates. Evolution. Members of this phylum, except for the photosynthetic chromerids, are parasitic and evolved from a free-living ancestor. This lifestyle is presumed to have evolved at the time of the divergence of dinoflagellates and apicomplexans. Further evolution of this phylum has been estimated to have occurred about . The oldest extant clade is thought to be the archigregarines. These phylogenetic relations have rarely been studied at the subclass level. The Haemosporidia are related to the gregarines, and the piroplasms and coccidians are sister groups. The Haemosporidia and the Piroplasma appear to be sister clades, and are more closely related to the coccidians than to the gregarines. Marosporida is a sister group to Coccidiomorphea. Janouškovec et al. 2015 presents a somewhat different phylogeny, supporting the work of others showing multiple events of plastids losing photosynthesis. More importantly this work provides the first phylogenetic evidence that there have also been multiple events of plastids becoming genome-free.
Argentine cuisine Argentine cuisine is described as a blending of cultures, from the Indigenous peoples of Argentina who focused on ingredients such as humita, potatoes, cassava, peppers, tomatoes, beans, and yerba mate, to Mediterranean influences brought by the Spanish during the colonial period. This was complemented by the significant influx of Italian and Spanish immigrants to Argentina during the 19th and 20th centuries, who incorporated plenty of their food customs and dishes such as pizzas, pasta and Spanish tortillas. Beef is a main part of the Argentine diet due to its vast production in the country's plains. In fact, Argentine annual consumption of beef has averaged per capita, approaching per capita during the 19th century; consumption averaged in 2007. Beyond "asado" (the Argentine barbecue), no other dish more genuinely matches the national identity. Nevertheless, the country's vast area, and its cultural diversity, have led to a local cuisine of various dishes. The great immigratory waves consequently imprinted a large influence in the Argentine cuisine, after all Argentina was the second country in the world with the most immigrants with 6.6 million, only second to the United States with 27 million, and ahead of other immigratory receptor countries such as Canada, Brazil, Australia, etc.
Argentine people have a reputation for their love of eating. Social gatherings are commonly centred on sharing a meal. Invitations to have dinner at home are generally viewed as a symbol of friendship, warmth, and integration. Sunday family lunch is considered the most significant meal of the week, whose highlights often include "asado" or pasta. Another feature of Argentine cuisine is the preparation of homemade food such as French fries, patties, and pasta to celebrate a special occasion, to meet friends, or to honour someone. Homemade food is also seen as a way to show affection. Argentine restaurants include a great variety of cuisines, prices, and flavours. Large cities tend to host everything from high-end international cuisine to "bodegones" (inexpensive traditional hidden taverns), less stylish restaurants, and bars and canteens offering a range of dishes at affordable prices. History. Amerindians lived in Argentina thousands of years before European explorers arrived. They mostly lived off of hunting, gathering, and fishing. Generally, the most common crops at this time were maize, potatoes, common beans, quinoa, and squash.
The Argentinian native people could be divided in three groups based on their main modality of acquiring food: Spanish settlers came to Argentina in 1536 and began building "chacras" where Amerindians would work to harvest the food. The arrival of Europeans brought Argentina into the Columbian Exchange, with ingredients from the Old World such as wheat, grapevine, figs, and several kinds of fruits being introduced to the country for the first time. It was also during the Spanish colonial period that cattle, goat, and pig farming were first introduced to Argentina, forming the foundation of the large Argentine beef industry. Between 1853 and 1955, 6.6 million immigrants came to live in Argentina from Europe (especially from Italy, Wales, Germany and Switzerland), the Near and Middle East, Russia and Japan. They contributed to the development of Argentine cuisine by encouraging the production of a wider variety of foods. They also bought lands where they built "chacras" and encouraged the growth of farming. By this point, Argentina was the country with most immigrants only second to the United States.
During the XIX century, social standing was not associated with access to food. The price of beef, fish, and bird meats was cheap and accessible. However, grains and wheat was scarce so bread was very expensive. Some of the most common dishes during this time were soups with pork chunks, cooked partridge with legumes, spinach bread, beef slices, and lamb stew. The most prominent spices were garlic, parsley, and pepper. By the turn of the century, Argentine Cuisine was on a constant decline due to shortage of several ingredients. However, eating habits began to shift with further immigration which facilitated a gastronomic revolution. Most immigrants in the 1900s came from Italy and Spain. The Italians introduced pizza, as well as a variety of pasta dishes, including spaghetti and lasagna. British, German, Jewish, and other immigrants also settled in Argentina, all bringing their styles of cooking and favorite foods with them. The British brought tea, starting the tradition of teatime. All of these cultures influenced the dishes of Argentina.
At this time, Italian cuisine began to really become a part of the cuisine. The neighborhood of La Boca, Buenos Aires, was the first big Italian hub, and from here plenty of traditionally Italian ingredients and eating habits expanded across the country. Different kinds of pastas such as long noodles or "tallarines", gnocchi, ravioli, and cannelloni filled with ricotta cheese became popular along with pizza, fainá (Argentinian version of the traditional Italian farinata), and milanesas. Different ways of preparing dishes were also adopted from Italian immigrants. These included the preparation of ice cream, fish, and shellfish. Spanish immigrants also left their mark, popularizing eating dry nuts, tomato sauce, pesto, olives, and olive oil. Additionally, deli stores started to incorporate traditional Iberian hams and sausages and great varieties of cheeses yet these were more limited. They were also mainly responsible for the massive diffusion of wine consumption, among some other habits. This occurred at the same time that other global products began arriving to Argentina such as saffron, cod, different varieties of beans, chickpeas, additional spices, chocolates, and tea.
Typical foods. Most regions of Argentina are known for their beef-oriented diet. Grilled meat from the "asado" (barbecue) is a staple, with steak and beef ribs especially common. The term "asado" itself refers to long strips of flank-cut beef ribs. Popular items such as "chorizo" (pork sausage), "morcilla" (blood sausage), "chinchulines" (chitterlings), "mollejas" (sweetbread), and other parts of the animal are also enjoyed. In Patagonia, however, lamb and chivito (goat) are eaten more frequently than beef. Whole lambs and goats are traditionally cooked over an open fire in a technique known as asado a la estaca. The most common condiment for asado is "chimichurri", a sauce of herbs, garlic and vinegar. Unlike other preparations, Argentines do not include chilli in their version of "chimichurri", but it does include a still-spicy, but milder form of red pepper, ají molido. Breaded and fried meats ("milanesas)" are used as snacks, in sandwiches, or eaten warm with mashed potatoes, "purée". "Empanadas," small pastries of meat, cheese, sweet corn, and many other fillings, are a common sight at parties and picnics, or as starters to a meal. They also vary in their looks, since they are folded with a traditional decorative edging called "repulgue". The "repulgue" is not just aesthetic, but also serves as a way to identify the flavor of each empanada since they are traditionally ordered in dozens where people mix and match flavors. Empanadas are one of the most important staples of this country due to the wide array of varieties.
The empanadas seen in Argentina today originate from a Spanish dish from the fifteenth century where travelers used easy-to-carry bread and filled it with a variety of ingredients. Eventually it evolved into a popular gastronomic item and spread across the world. Variations of empanadas both inside and outside of Argentina include the "empanada gallega" (Galician "empanada"), a large round meat pie made most commonly with tuna and mackerel ("caballa" in Spanish). Vegetables and salads are also eaten by Argentines; tomatoes, onions, lettuce, eggplants, squashes, and zucchini are common side dishes. Italian staples, such as pizza and pasta, are eaten as commonly as beef. "Fideos" (noodles), "tallarines" ("fettuccine" and "tagliatelle"), "ñoquis" ("gnocchi") are traditionally served on the 29th day of the month, "ravioles", and "canelones" ("cannelloni") can be bought freshly made in many establishments in the larger cities. Italian-style ice cream is served in large parlours and even drive-through businesses. Other Italian staples are "polenta", , and "pastafrola".
In Chubut, the Welsh community is known for its teahouses, offering scones and "torta galesa", which is rather like "torta negra". A fosforito is a ham and cheese sandwich using puff pastry as the bread. "Sandwiches de miga" are delicate sandwiches made with crustless buttered English bread, very thinly sliced cured meat, cheese, and lettuce. They are often purchased from entrepreneurial home cooks and may be eaten for a light evening meal. A sweet paste, "dulce de leche" is another treasured national food, used to fill cakes and pancakes, spread over toasted bread for breakfast, or served with ice cream. In terms of sweets, "Alfajores" are another key staple. These are shortbread cookies sandwiched together with chocolate and "dulce de leche" or a fruit paste. The "policeman's" or "truck driver's" sweet is cheese with quince paste or "dulce de membrillo". "Dulce de batata" is made of sweet potato/yam: this with cheese is the "Martín Fierro"'s sweet. Additionally, ice cream shops or "heladerias" are a big boom especially in the city of Buenos Aires. Argentinian ice cream comes in plenty of flavors (from fruits to cheesecake and even duce de leche flavors) and has a special smoothness as it follows a recipe very similar to that of Italian gelato.
Apples, pears, peaches, kiwifruits, avocados, and plums are major exports. A traditional drink of Argentina is an infusion called "mate" (in Spanish, "mate", with the accent on the first syllable [MAH-teh]). The name comes from the hollow gourd from which it is traditionally drunk. The "mate" (gourd) or other small cup is filled about three-quarters full with "yerba mate", the dried leaves and twigs of the "Ilex paraguariensis". The drink, which is rather bitter, is sipped through a metal or cane straw called a "bombilla". "Mate" can be sweetened with sugar, or flavoured with aromatic herbs or dried orange peel. Hot but not boiling water is poured into the gourd, drunk, then the "mate" is refilled. The "mate" is nearly full of leaves, so each refill only makes a small drink, but many refills are possible before the "yerba" is spent. In small gatherings it is traditional for one "mate" to be passed from person to person, filled by whoever has the kettle. It is customary not to thank the refiller routinely; a final "gracias" (thank you) implies that the drinker has had enough.
Drinking "mate" together is an important social ritual. "Mate cocido" is the same leaf, which rather than brewed is boiled and served, like tea, with milk and sugar to taste. Other typical drinks include wine (sometimes with soda water added); tea and coffee are equally important. Quilmes is the national brand of pale lager, named after the town of Quilmes, Buenos Aires, where it was first produced. Ingredients. Argentine cuisine uses locally-grown cereals, grains, oil seeds, fruits and vegetables, as well as meat. Meat products have been dominant in the country since the 16th century. The country is regarded as a major beef, pork and poultry producing and consuming country. Certain areas such as those located in the south are usually engaged in activities involving sheep and lamb breeding, and shellfish, crustaceans, molluscs and salmonides fishing. The vast breeding activity involving any type of cattle has given rise to a highly developed dairy industry that includes products like cow, sheep and camelide, "dulce de leche" and yogurts. Some of the cheeses from Argentina are "reggianito", "sardo", "provoleta" and "cremoso". Argentina can also be conceived as a great industry engaged in the production of dried fruits, olives, all types of oils and spices.
In the Mesopotamia region, river fish such as silverside, surubi, dorado or boga are common. Regional differences. Argentine cuisine is heavily influenced by its European roots and has regional variations. "Asado", "dulce de leche", "empanadas", and "yerba mate" are found throughout Argentina. In many parts of the country, food is prepared differently and different kinds of foods are made; this includes to a smaller degree food from pre-Columbian times, as in the Northwest. Central region and la Pampa. This region is composed of the city of Buenos Aires, Buenos Aires Province, Córdoba, La Pampa, Santa Fe, and Entre Ríos. This region, especially within the larger urban areas of Buenos Aires, Rosario, and Córdoba welcomed European immigrants. These were especially of Italian and Spanish descent. Nevertheless, there was also a migratory flow of German, Swiss, and Middle Eastern immigrants arriving in Argentina. As a result, dishes such as pasta, pizza, pucheros (stews), croquetas (fritters), sauces, embutidos (sausages), and chicken and meat courses brought a wider scope of options to daily menus. The bread-making, dessert, pastry, and dairy industries have achieved considerable development in this region.
The above-mentioned dishes have developed a distinctively Argentine nuance. That is why, for example, Argentine pasta includes a wide variety of dishes ranging from spaghetti, fusiles (fusilli), ñoquis (gnocchi), ravioli, cintas (pasta ribbons), and lasagne to the Argentine-made sorrentinos, agnolottis (agnolotti), canelones (cannelloni), and fetuchines (fettuccine). Pizza—made with very thin, and sometimes thick, high-rising doughs, with or without cheese, cooked in the oven or "a la piedra" (on a stone oven), and stuffed with numerous ingredients—is a dish which can be found in nearly every corner of the country. Buenos Aires, Rosario, and Córdoba also serve it with fainá, which is a chick pea-flour dough placed over the piece of pizza. People say that what makes Argentine pizza unique is the blending of Italian and Spanish cultures. At the turn of the 19th century, immigrants from Naples and Genoa opened the first pizza bars, though Spanish residents subsequently owned most of the pizza businesses. Bread products are consumed all around the country. The deeply rooted bread, pastry, and dessert-making tradition derive from blending the above nationalities' products. Bakeries sell not only a wide scope of bread, cookies, and cakes, but also pastries. The latter resembles a sort of roll pastry whose main dough ingredient is either butter or fat and which may be simple or stuffed with dulce de leche, milk, jam, crema pastel, or quince or apple jelly, among other fillings. The most popular type of pastry is said to be that of "medialunas" (singular: "medialuna," literally half-moon, that is to say, crescent), based upon French croissants. Sandwiches de miga are another type of bread products; they are made only with thin layers of white bread (generally referred to as crustless bread) and stuffed with food items ranging from ham and cheese to other more sophisticated combinations such as raw ham, tomatoes, olives, hard-boiled eggs, tuna, lettuce, red pepper, and the like.
Desserts and sweets are usually stuffed or covered with dulce de leche. The latter can be eaten alone or on top of cakes, alfajores, panqueques (crepes), and pastries, or as a topping spread over flan de leche. Chantilly cream is widely consumed and used in preparing sweets and desserts. Additionally, cakes, sponge cakes, and puddings are very popular dishes. Italian ice creams in this region also achieved a significant degree of development by adding local flavours that somehow preserved the local spirit involved in their preparation. Although asado is eaten all over the country, its origin may be traced back to the Pampas. It entails many types of meat, which are generally eaten as follows: achuras (offal), morcilla (blood sausage), and sometimes also a provoleta (a piece of provolone cheese cooked on the grill with oregano) are eaten first. Then comes the choripán (a kind of spiced sausage made with pork or lamb and placed between two slices of bread), and finally meat such as asado de tira, vacío (flank steak), lomo (tenderloin), colita de cuadril (rump), matambre (rolled stuffed steak cut into slices and served cold), entraña (hanger steak); the list is never-ending. "Cabrito al asador" (roast kid or goat) is frequently eaten in the province of Córdoba.
Northwest and Cuyo. This region includes the provinces of Jujuy, Salta, Catamarca, Tucumán, Santiago del Estero, La Rioja, San Juan, Mendoza, and San Luis. It is also regarded as the one most influenced by Native Americans, and its foods are closely linked to the Andean-Incan tradition. When preparing regional dishes, potatoes and corn or wheat are almost always used, including quinoa (a cereal typically used in Incan cuisine), peppers, squashes, tomatoes and in some provinces beans. The most celebrated dishes are humita and tamal, in which the corn husk is stuffed with the corn filling itself, seasonings or meat. This region is the most suitable to taste empanadas, particularly those stuffed with meat and offering different types of tempting varieties such as the "meat empanada", salteña also filled with potatoes, or the "empanada tucumana", which is stuffed with matambre and cut with a knife, or empanadas made with cheese. Empanadas are individual-sized and closed savoury pastries which may be fried or baked in the oven and are generally eaten with the hands.
Stews such as locro, carbonada, pollo al disco, and cazuelas (casseroles) are also typical dishes characterizing this region, which also include pumpkin or potato pudding stuffed with meat. There are also some local holidays in this region related to food. For example, in Salta they hold a festival dedicated to a locally grown bean similar to Edamame. During this holiday, the traditional foods of corn and beans are celebrated. Meals of all kinds are eaten, always with these two ingredients as a side dish, and even competitions of who can eat a set number of beans in the shortest period of time are held. Mesopotamia. The humid and verdant area of north-east Argentina known as Mesopotamia, comprising the provinces of Chaco, Corrientes, Misiones and Formosa is another area heavily influenced by Native Americans, particularly by the Guaraní tribe. Abounding in rivers and shores, it offers a wide diversity of fish species, such as dorado, pacú, surubi, boga and silverside. Widely grown in this area, cassava is typically included in the region's dishes, as are other components of meals, such as the chipá (cassava and cheese bread). However, in this area Cassava is cooked alone too, boiled or fried, often as a side dish for Asado and empanadas. As well, mbeyú, chipá avatí, sopa paraguaya, sopa correntina, chipa solo or chipá con carne, el quibebé, el borí borí, chipá guasú o pastel de choclo, mbaipy, chipá mbocá o chipá caburé and some other similar meals that have as basis:manioc, corn, cheese and, sometimes, some meat.. Chipá from Cassava is often eaten during breakfast with yerba mate, prepared with hot water, or with café con leche. Sopa Paraguaya and pastel/Carta de Choclo are eaten for lunch or dinner. As regards products made with sugar, Papaya (mamón in Argentine Spanish) jam is typical of the north of this region.
The principal product of this region is certainly yerba mate. Consumed countrywide, this product features a peculiarity of its own in this area: it is not only prepared with hot water but, driven by the region's high temperatures, it is common to see it prepared with cold water as well, in which case the beverage is known as tereré. Patagonia. The large southern region of Patagonia is made up of the provinces Neuquén, Río Negro, Chubut, Santa Cruz and Tierra del Fuego. This area also includes the Antarctica and Islas del Atlántico Sur. (or southern atlantic islands). Their most typical food ingredients include fish and seafood from the sea and rivers and the products of the sheep that are widely farmed there. Marine species such as salmon, spider crabs, squid and other shellfish and molluscs may be caught in the Atlantic Ocean. There are trout in the rivers. The many berries grown in the area include cherries, bilberries, strawberries, rosa mosqueta and elders, which are made into jams. The Northern and Central European settlements in this region have built up large-scale production of chocolate and its by-products. Viennese and German cuisine and pastries are also typically associated with this region.
Mutton and lamb, together with wild boar and venison tend to make up the region's meat-based dishes. Also typical of the southern region are smoked products, including salmon, stag, wild boar, and pheasant. Patagonia has been profoundly influenced by the tribes living there since long before Europeans arrived, in particular, the Mapuches and the Araucanos. A typical dish prepared by the latter is the curanto (a term meaning "hot stone"). Its preparation involves making a fire in a hole about 150 cm deep in the ground, and heating stones in it. A bed of nalca or maqui leaves is arranged on top of the stones, and ingredients are added in turn on top. Ingredients vary, but may include beef, lamb, pork, chicken, Argentine chorizos (pork sausages), potatoes, sweet potatoes, apples and holed squashes filled with cheese, cream and peas. The food is covered with leaves and damp pieces of cloth to keep the heat in, and covered with plenty of soil. Alcoholic beverages. Though wine ("vino") has traditionally been the most popular alcoholic beverage in Argentina, beer ("cerveza"; the Italian "birra" is frequently used) in recent decades has competed with wine in popularity. Breweries appeared in Argentina at the end of the 1860s, started by Alsatian colonists. The first were nearly all in the downtown of Buenos Aires ("el égido de la Ciudad Autónoma de Buenos Aires"), and soon Polish brewers began industrial production of beer: San Carlos in the province of Santa Fe, Río Segundo and Córdoba in the province of Córdoba, Quilmes and Llavallol on the outskirts of La Plata (in Buenos Aires Province), San Miguel de Tucumán in the province of Tucumán and on the outskirts of the cities of Mendoza and Salta.
The local consumption of beer has risen dramatically in the last generation: Argentines consumed 233 million litres in 1980 and 1.57 billion in 2007 (40 litres per capita). Outpacing that of wine since 2001, the growing production and consumption of beer have supported the existence of related events, for example, beer festivals called "Oktoberfests" or "Fiestas de la Cerveza" in locations that have a significant German population (Villa General Belgrano in Córdoba, San Carlos and Esperanza in the province of Santa Fe, etc.). Such celebrations copy, in an Argentine manner, Munich's "Oktoberfest", and similarly are tourist attractions. However, the presence of a vigorous population of Celtic lineage, principally of Irish origin, has supported the creation of other celebrations of beer, often for marketing purposes, such as Saint Patrick's Day ("Día de San Patricio"), patron of Ireland, which is celebrated with abundant libations. The consumption of alcoholic beverages in Argentina is similar to that of the United States and somewhat lower than the Western European average. Argentines enjoy a variety of alcoholic beverages and Argentina can boast a varied array of "elaboraciones", whether industrial or artisanal. Besides beer and wine, Argentines frequently drink cider (here again, the heritage comes from Spain and Italy, more precisely from Asturias and Campania). Cider is the most popular beverage of the middle and lowers economic classes at Christmas and New Year (the upper classes proverbially preferring to celebrate with locally produced champagne, although real old-line "creole" aristocrats will still drink cider, which is much more traditional).
Other widely consumed spirits are "aguardiente" (firewater) made from sugar cane, known as "caña quemada" ("burnt cane") or, simply, 'caña' ("cane"). A folkloric note about "caña quemada": until 21 June it is traditional to drink "caña quemada" with "ruda macho" (a variant of common rue), it is supposed that this mixture prevents the flu and other illnesses. "Caña" competes, mainly in rural areas, with gin ("ginebra"—as in the Dutch kind of gin.) The bitter spirit Fernet, and particularly the Italian brand Fernet-Branca, is highly popular in Argentina. (A study in 2017 found that Argentines consume more than 75% of all fernet produced globally.) Fernet is most commonly enjoyed as a mixed drink with Coca-Cola. Given Fernet's qualities as a digestive aid, it is a common choice for an after-dinner digestif. There are many artisanally produced liqueurs (distilled, flavoured alcoholic beverages) in Argentina, for example, those flavoured with orange, egg, anise, coffee, cherry and, inevitably, "dulce de leche". The "Hesperidina" is a type of liqueur made from orange peels, invented in Argentina around 1890. One may also encounter "chitronchelo" or (in Italian) "citronella", based on lemon. This beverage arrived with immigrants from the Mezzogiorno and is produced both artisanally and industrially (for example, at Mar del Plata).
Non-alcoholic specialties. Argentines enjoy a wide variety of non-alcoholic infusions (although now and then both "families" are mixed; the for example, is mate mixed with "caña" or gin). Among these, "mate" has long been the most widely enjoyed; in 2006, over 700,000 metric tons were harvested in Argentina, mostly for domestic consumption. Mate is also one of the top exports from Argentina, as it is valued all over the world. The fact that mate is so prevalent in the Southern Cone, however, should not necessarily make visitors think that other infusions are rare in the region; in Argentina especially, given the strong European cultural imprint, the consumption of coffee is very common (141 cups per capita, annually). Chocolate infusions are also popular (the eating of chocolate is a Spanish influence, although the plant originated in Mesoamerica). This consumption grows during autumn and winter, or in the cold regions of the country; there are two dates where consumption of chocolate infusions is traditional in the primary educational centres: 25 May and 9 July, that is, the two national dates of Argentina.
English cultural influence (reinforced at the end of the 19th century and the beginnings of the 20th by British contacts with the Far East) has also made the consumption of tea very common. Medicinal herbs are common in the whole country; among the most popular are: chamomile, lanceleaf, "boldo", "poleo", "peperina", "carqueja", thyme, "canchalagua", rue ("macho" and "hembra", that is, "male" and "female"), mallow, rosemary, passion flower, "bira bira", "palán palán", "muña muña", to mention only the main ones. Many of these herbs are also used in apéritifs and bitters, whether alcoholic or not. Popular short-order dishes. Common "restoranes" or "restaurantes" and (grill restaurants) nearly anywhere in Argentina today serve (into the small hours) quickly prepared meals that in the course of the 20th century came to be known as "minutas", "short-order dishes". Some of the dishes included in the category of "minutas" are "milanesas", "churrascos", "bifes" (beefsteaks), "escalopes", "tallarines", "ravioles" (ravioli), "ñoquis" (gnocchi), although some are very typical of locations that sell food: ""bifes" and "milanesas" are served "a caballo"" ("on horseback", with fried egg on top), ""milanesa completa" (a "milanesa" with two fried eggs and French fries), "revuelto Gramajo", "colchón de arvejas" (an omelette made with peas), "suprema de pollo" (chicken supreme, usually breaded as a "milanesa"), "matambres", "lengua a la vinagreta"" (pickled tongue), and "sandwiches" ("sandwiches de miga") are made with sliced white bread, rather than, say, rolls.
The most common sandwiches are those made of "milanesa", baked ham and cheese, "pan de miga", toast, "pebetes", "panchos" (hot dogs), "choripanes", "morcipanes", etc.; from Montevideo comes a different species of sandwich called the "chivito", even though it contains no goat meat. "Picadas", which are consumed at home or in bars, cafés, ""cafetines" and "bodegones" are also popular; they consist of an ensemble of plates containing cubes of cheese (typically from Mar del Plata or Chubut), pieces of salame, olives in brine, french fries, "maníes" (peanuts), etc.; "picada"s are eaten accompanied by an alcoholic beverage ("fernet"", beer, wine with soda, to give some common examples). The people of Argentina greatly enjoy "helado" (ice creams of Italian lineage or sorbets Spanish lineage). In Spanish colonial times, a type of sorbet was made from hail or snow. Eating habits. Breakfast typically is small and consists of coffee (or mate) and pastry. In most parts of Argentina, lunch is the largest meal of the day. Excluding the largest cities, such as Buenos Aires, Rosario or Cordoba, most towns close for lunchtime. This is when most people return home to enjoy a large meal and siesta. Traditional lunches in Argentina are long and well developed. Argentines often have a light evening snack (called a "merienda" – typically a coffee or mate and a pastry) and it is common to not eat dinner until 9 at night, or even later on weekends.
Ad hominem , short for , refers to several types of arguments that are usually fallacious. Often currently this term refers to a rhetorical strategy where the speaker attacks the character, motive, or some other attribute of the person making an argument rather than the substance of the argument itself. This avoids genuine debate by creating a diversion often using a totally irrelevant, but often highly charged attribute of the opponent's character or background. The most common form of this fallacy is "A" makes a claim of "fact", to which "B" asserts that "A" has a personal trait, quality or physical attribute that is repugnant thereby going off-topic, and hence "B" concludes that "A" has their "fact" wrongwithout ever addressing the point of the debate. Other uses of the term are more traditional, referring to arguments tailored to fit a particular audience, and may be encountered in specialized philosophical usage. These typically refer to the dialectical strategy of using the target's own beliefs and arguments against them, while not agreeing with the validity of those beliefs and arguments. arguments were first studied in ancient Greece; John Locke revived the examination of arguments in the 17th century.
A common misconception is that an attack is synonymous with an insult. This is not true, although some arguments may be insulting by the person receiving the argument. History. The various types of arguments have been known in the West since at least the ancient Greeks. Aristotle, in his work "Sophistical Refutations", detailed the fallaciousness of putting the questioner but not the argument under scrutiny. His description was somewhat different from the modern understanding, referring to a class of sophistry that applies an ambiguously worded question about people to a specific person. The proper refutation, he wrote, is not to debate the attributes of the person () but to address the original ambiguity. Many examples of ancient non-fallacious arguments are preserved in the works of the Pyrrhonist philosopher Sextus Empiricus. In these arguments, the concepts and assumptions of the opponents are used as part of a dialectical strategy against them to demonstrate the unsoundness of their own arguments and assumptions. In this way, the arguments are to the person (), but without attacking the properties of the individuals making the arguments. This kind of argument is also known as "argument from commitment".
Italian Galileo Galilei and British philosopher John Locke also examined the argument from commitment, a form of the argument, meaning examining an argument on the basis of whether it stands true to the principles of the person carrying the argument. In the mid-19th century, the modern understanding of the term started to take shape, with the broad definition given by English logician Richard Whately. According to Whately, arguments were "addressed to the peculiar circumstances, character, avowed opinions, or past conduct of the individual". Over time, the term acquired a different meaning; by the beginning of the 20th century, it was linked to a logical fallacy, in which a debater, instead of disproving an argument, attacked their opponent. This approach was also popularized in philosophical textbooks of the mid-20th century, and it was challenged by Australian philosopher Charles Leonard Hamblin in the second half of the 20th century. In a detailed work, he suggested that the inclusion of a statement against a person in an argument does not necessarily make it a fallacious argument since that particular phrase is not a premise that leads to a conclusion. While Hablin's criticism was not widely accepted, Canadian philosopher Douglas N. Walton examined the fallaciousness of the argument even further. Nowadays, except within specialized philosophical usaɡe, use of the term signifies a straight attack at the character and ethos of a person, in an attempt to refute their argument.
Terminology. The Latin phrase stands for 'argument against the person'. here means 'against' but could also mean 'to' or 'towards'. The terms and have been used specifically when the person receiving the criticism is female but the term (accusative of ) was gender-neutral in Latin. Types of "ad hominem" arguments. Fallacious reasoning is categorized among informal fallacies, more precisely as a genetic fallacy, a subcategory of fallacies of irrelevance. fallacies can be separated into various types, such as , circumstantial , guilt by association, and abusive . All of them are similar to the general scheme of argument, that is instead of dealing with the essence of someone's argument or trying to refute it, the interlocutor is attacking the character of the proponent of the argument and concluding that it is a sufficient reason to drop the initial argument. "Tu quoque". (literally 'you also') is a response to an argument that itself goes . appears as: An example given by professor George Wrisley to illustrate the above is:
A businessman and a politician are giving a lecture at a university about how good his company is and how nicely the system works. A student asks him "Is it true that you and your company are selling weapons to third world rulers who use those arms against their own people?" and the businessman replies "Is it true that your university gets funding by the same company that you are claiming is selling guns to those countries? You are not a white dove either". The student's accusation is not fallacious, as it is relevant to the narrative the businessman is trying to project. On the other hand, the businessman's attack on the student (that is, the student being inconsistent) is irrelevant to the opening narrative. So the businessman's response is fallacious. Canadian philosopher Christopher Tindale approaches somewhat different the fallacy. According to Tindale, a fallacy appears when a response to an argument is made on the history of the arguer. This argument is also invalid because it does not disprove the premise; if the premise is true, then source A may be a hypocrite or even changed their mind, but this does not make the statement less credible from a logical perspective. A common example, given by Tindale, is when a doctor advises a patient to lose weight, but the patient argues that there is no need for him to go on a diet because the doctor is also overweight.
Circumstantial. Circumstantial ' points out that someone is in circumstances (for instance, their job, wealth, property, or relations) such that they are disposed to take a particular position. It constitutes an attack on the bias of a source. As with other types of the argument, the circumstantial could be fallacious or not. It could be fallacious because a disposition to make a certain argument does not make the argument invalid; this overlaps with the genetic fallacy (an argument that a claim is incorrect due to its source). But it also may be a sound argument, if the premises are correct and the bias is relevant to the argument. A simple example is: a father may tell his daughter not to start smoking because she will damage her health, and she may point out that he is or was a smoker. This does not alter the fact that smoking might cause various diseases. Her father's inconsistency is not a proper reason to reject his claim. Douglas N. Walton, philosopher and pundit on informal fallacies, argues that a circumstantial argument can be non-fallacious. This could be the case when someone (A) attacks the personality of another person (B), making an argument (a) while the personality of B is relevant to argument "a", i.e. B talks as an authority figure. To illustrate this reasoning, Walton gives the example of a witness at a trial: if he had been caught lying and cheating in his own life, should the jury take his word for granted? No, according to Walton.
Guilt by association. Guilt by association, that is accusing an arguer because of his alleged connection with a discredited person or group, can sometimes also be a type of fallacy when the argument attacks a source because of the similarity between the views of someone making an argument and other proponents of the argument. This form of the argument is as follows: Academic Leigh Kolb gives as an example that the 2008 US vice-presidential candidate Sarah Palin attacked Barack Obama for having worked with Bill Ayers, who had been a leader in the Weather Underground terrorist group in the 1960s. Despite Obama denouncing every act of terrorism, his opponents still associated him with terrorism. Guilt by association is frequently found in social and political debates. It also appears after major events (such as scandals and terrorism) linked to a specific group. Kolb cites the peak of attacks against Muslims in the US after the September 11 attacks. Abusive "ad hominem". Abusive argument (or direct ) is associated with an attack to the character of the person carrying an argument. This kind of argument, besides usually being fallacious, is also counterproductive, as a proper dialogue is hard to achieve after such an attack.
Key issues in examining an argument to determine whether it is an fallacy or not are whether the accusation against the person stands true or not, and whether the accusation is relevant to the argument. An example is a dialogue at the court, where the attorney cross-examines an eyewitness, bringing to light the fact that the witness was convicted in the past for lying. If the attorney's conclusion is that the witness is lying, that would be wrong. But if his argument would be that the witness should not be trusted, that would not be a fallacy. Argument from commitment. An argument from commitment is a type of valid argument that employs, as a dialectical strategy, the exclusive use of the beliefs, convictions, and assumptions of those holding the position being argued against, i.e., arguments constructed on the basis of what other people hold to be true. This usage is generally only encountered in specialist philosophical usage or in pre-20th century usages. This type of argument is also known as the argument (Latin for 'from what has been conceded already').
Use in debates. fallacies are considered to be uncivil and do not help creating a constructive atmosphere for dialogue to flourish. An attack is an attack on the character of the target who tends to feel the necessity to defend himself or herself from the accusation of being hypocritical. Walton has noted that it is so powerful of an argument that it is employed in many political debates. Since it is associated with negativity and dirty tricks, it has gained a bad fame, of being always fallacious. Author Eithan Orkibi, having studied Israeli politics prior to elections, described two other forms of attacks that are common during election periods. They both depend on the collective memory shared by both proponents and the audience. The first is the "precedent ", according to which the previous history of someone means that they do not fit for the office. It goes like this: "My opponent was (allegedly) wrong in the past, therefore he is wrong now". The second one is a behavioral : "my opponent was not decent in his arguments in the past, so he is not now either". These kinds of attacks are based on the inability of the audience to have a clear view of the amount of false statements by both parts of the debate.
Criticism as a fallacy. Walton has argued that reasoning is not always fallacious, and that in some instances, questions of personal conduct, character, motives, etc., are legitimate and relevant to the issue, as when it directly involves hypocrisy, or actions contradicting the subject's words. The philosopher Charles Taylor has argued that reasoning (discussing facts about the speaker or author relative to the value of his statements) is essential to understanding certain moral issues due to the connection between individual persons and morality (or moral claims), and contrasts this sort of reasoning with the apodictic reasoning (involving facts beyond dispute or clearly established) of philosophical naturalism.
Analysis of algorithms In computer science, the analysis of algorithms is the process of finding the computational complexity of algorithms—the amount of time, storage, or other resources needed to execute them. Usually, this involves determining a function that relates the size of an algorithm's input to the number of steps it takes (its time complexity) or the number of storage locations it uses (its space complexity). An algorithm is said to be efficient when this function's values are small, or grow slowly compared to a growth in the size of the input. Different inputs of the same size may cause the algorithm to have different behavior, so best, worst and average case descriptions might all be of practical interest. When not otherwise specified, the function describing the performance of an algorithm is usually an upper bound, determined from the worst case inputs to the algorithm. The term "analysis of algorithms" was coined by Donald Knuth. Algorithm analysis is an important part of a broader computational complexity theory, which provides theoretical estimates for the resources needed by any algorithm which solves a given computational problem. These estimates provide an insight into reasonable directions of search for efficient algorithms.
In theoretical analysis of algorithms it is common to estimate their complexity in the asymptotic sense, i.e., to estimate the complexity function for arbitrarily large input. Big O notation, Big-omega notation and Big-theta notation are used to this end. For instance, binary search is said to run in a number of steps proportional to the logarithm of the size of the sorted list being searched, or in , colloquially "in logarithmic time". Usually asymptotic estimates are used because different implementations of the same algorithm may differ in efficiency. However the efficiencies of any two "reasonable" implementations of a given algorithm are related by a constant multiplicative factor called a "hidden constant". Exact (not asymptotic) measures of efficiency can sometimes be computed but they usually require certain assumptions concerning the particular implementation of the algorithm, called a model of computation. A model of computation may be defined in terms of an abstract computer, e.g. Turing machine, and/or by postulating that certain operations are executed in unit time.
For example, if the sorted list to which we apply binary search has elements, and we can guarantee that each lookup of an element in the list can be done in unit time, then at most time units are needed to return an answer. Cost models. Time efficiency estimates depend on what we define to be a step. For the analysis to correspond usefully to the actual run-time, the time required to perform a step must be guaranteed to be bounded above by a constant. One must be careful here; for instance, some analyses count an addition of two numbers as one step. This assumption may not be warranted in certain contexts. For example, if the numbers involved in a computation may be arbitrarily large, the time required by a single addition can no longer be assumed to be constant. Two cost models are generally used: The latter is more cumbersome to use, so it is only employed when necessary, for example in the analysis of arbitrary-precision arithmetic algorithms, like those used in cryptography. A key point which is often overlooked is that published lower bounds for problems are often given for a model of computation that is more restricted than the set of operations that you could use in practice and therefore there are algorithms that are faster than what would naively be thought possible.
Run-time analysis. Run-time analysis is a theoretical classification that estimates and anticipates the increase in "running time" (or run-time or execution time) of an algorithm as its "input size" (usually denoted as ) increases. Run-time efficiency is a topic of great interest in computer science: A program can take seconds, hours, or even years to finish executing, depending on which algorithm it implements. While software profiling techniques can be used to measure an algorithm's run-time in practice, they cannot provide timing data for all infinitely many possible inputs; the latter can only be achieved by the theoretical methods of run-time analysis. Shortcomings of empirical metrics. Since algorithms are platform-independent (i.e. a given algorithm can be implemented in an arbitrary programming language on an arbitrary computer running an arbitrary operating system), there are additional significant drawbacks to using an empirical approach to gauge the comparative performance of a given set of algorithms.
Take as an example a program that looks up a specific entry in a sorted list of size "n". Suppose this program were implemented on Computer A, a state-of-the-art machine, using a linear search algorithm, and on Computer B, a much slower machine, using a binary search algorithm. Benchmark testing on the two computers running their respective programs might look something like the following: Based on these metrics, it would be easy to jump to the conclusion that "Computer A" is running an algorithm that is far superior in efficiency to that of "Computer B". However, if the size of the input-list is increased to a sufficient number, that conclusion is dramatically demonstrated to be in error: Computer A, running the linear search program, exhibits a linear growth rate. The program's run-time is directly proportional to its input size. Doubling the input size doubles the run-time, quadrupling the input size quadruples the run-time, and so forth. On the other hand, Computer B, running the binary search program, exhibits a logarithmic growth rate. Quadrupling the input size only increases the run-time by a constant amount (in this example, 50,000 ns). Even though Computer A is ostensibly a faster machine, Computer B will inevitably surpass Computer A in run-time because it is running an algorithm with a much slower growth rate.
Orders of growth. Informally, an algorithm can be said to exhibit a growth rate on the order of a mathematical function if beyond a certain input size , the function times a positive constant provides an upper bound or limit for the run-time of that algorithm. In other words, for a given input size greater than some 0 and a constant , the run-time of that algorithm will never be larger than . This concept is frequently expressed using Big O notation. For example, since the run-time of insertion sort grows quadratically as its input size increases, insertion sort can be said to be of order . Big O notation is a convenient way to express the worst-case scenario for a given algorithm, although it can also be used to express the average-case — for example, the worst-case scenario for quicksort is , but the average-case run-time is . Empirical orders of growth. Assuming the run-time follows power rule, , the coefficient can be found by taking empirical measurements of run-time } at some problem-size points }, and calculating so that . In other words, this measures the slope of the empirical line on the log–log plot of run-time vs. input size, at some size point. If the order of growth indeed follows the power rule (and so the line on the log–log plot is indeed a straight line), the empirical value of will stay constant at different ranges, and if not, it will change (and the line is a curved line)—but still could serve for comparison of any two given algorithms as to their "empirical local orders of growth" behaviour. Applied to the above table:
It is clearly seen that the first algorithm exhibits a linear order of growth indeed following the power rule. The empirical values for the second one are diminishing rapidly, suggesting it follows another rule of growth and in any case has much lower local orders of growth (and improving further still), empirically, than the first one. Evaluating run-time complexity. The run-time complexity for the worst-case scenario of a given algorithm can sometimes be evaluated by examining the structure of the algorithm and making some simplifying assumptions. Consider the following pseudocode: 1 "get a positive integer n from input" 2 if n > 10 3 print "This might take a while..." 4 for i = 1 to n 5 for j = 1 to i 6 print i * j 7 print "Done!" A given computer will take a discrete amount of time to execute each of the instructions involved with carrying out this algorithm. Say that the actions carried out in step 1 are considered to consume time at most "T"1, step 2 uses time at most "T"2, and so forth. In the algorithm above, steps 1, 2 and 7 will only be run once. For a worst-case evaluation, it should be assumed that step 3 will be run as well. Thus the total amount of time to run steps 1–3 and step 7 is:
The loops in steps 4, 5 and 6 are trickier to evaluate. The outer loop test in step 4 will execute ( "n" + 1 ) times, which will consume "T"4( "n" + 1 ) time. The inner loop, on the other hand, is governed by the value of j, which iterates from 1 to "i". On the first pass through the outer loop, j iterates from 1 to 1: The inner loop makes one pass, so running the inner loop body (step 6) consumes "T"6 time, and the inner loop test (step 5) consumes 2"T"5 time. During the next pass through the outer loop, j iterates from 1 to 2: the inner loop makes two passes, so running the inner loop body (step 6) consumes 2"T"6 time, and the inner loop test (step 5) consumes 3"T"5 time. Altogether, the total time required to run the inner loop "body" can be expressed as an arithmetic progression: which can be factored as The total time required to run the inner loop "test" can be evaluated similarly: which can be factored as Therefore, the total run-time for this algorithm is: which reduces to As a rule-of-thumb, one can assume that the highest-order term in any given function dominates its rate of growth and thus defines its run-time order. In this example, n2 is the highest-order term, so one can conclude that . Formally this can be proven as follows:
A more elegant approach to analyzing this algorithm would be to declare that ["T"1.."T"7] are all equal to one unit of time, in a system of units chosen so that one unit is greater than or equal to the actual times for these steps. This would mean that the algorithm's run-time breaks down as follows: Growth rate analysis of other resources. The methodology of run-time analysis can also be utilized for predicting other growth rates, such as consumption of memory space. As an example, consider the following pseudocode which manages and reallocates memory usage by a program based on the size of a file which that program manages: while "file is still open:" let n = "size of file" for "every 100,000 kilobytes of increase in file size" "double the amount of memory reserved" In this instance, as the file size n increases, memory will be consumed at an exponential growth rate, which is order . This is an extremely rapid and most likely unmanageable growth rate for consumption of memory resources. Relevance. Algorithm analysis is important in practice because the accidental or unintentional use of an inefficient algorithm can significantly impact system performance. In time-sensitive applications, an algorithm taking too long to run can render its results outdated or useless. An inefficient algorithm can also end up requiring an uneconomical amount of computing power or storage in order to run, again rendering it practically useless.
Constant factors. Analysis of algorithms typically focuses on the asymptotic performance, particularly at the elementary level, but in practical applications constant factors are important, and real-world data is in practice always limited in size. The limit is typically the size of addressable memory, so on 32-bit machines 232 = 4 GiB (greater if segmented memory is used) and on 64-bit machines 264 = 16 EiB. Thus given a limited size, an order of growth (time or space) can be replaced by a constant factor, and in this sense all practical algorithms are for a large enough constant, or for small enough data. This interpretation is primarily useful for functions that grow extremely slowly: (binary) iterated logarithm (log*) is less than 5 for all practical data (265536 bits); (binary) log-log (log log "n") is less than 6 for virtually all practical data (264 bits); and binary log (log "n") is less than 64 for virtually all practical data (264 bits). An algorithm with non-constant complexity may nonetheless be more efficient than an algorithm with constant complexity on practical data if the overhead of the constant time algorithm results in a larger constant factor, e.g., one may have formula_8 so long as formula_9 and formula_10.
For large data linear or quadratic factors cannot be ignored, but for small data an asymptotically inefficient algorithm may be more efficient. This is particularly used in hybrid algorithms, like Timsort, which use an asymptotically efficient algorithm (here merge sort, with time complexity formula_11), but switch to an asymptotically inefficient algorithm (here insertion sort, with time complexity formula_12) for small data, as the simpler algorithm is faster on small data.
Ælle of Sussex Ælle (also Aelle or Ella) is recorded in much later medieval sources as the first king of the South Saxons, reigning in what is now called Sussex, England, from 477 to perhaps as late as 514. According to the "Anglo-Saxon Chronicle", Ælle and three of his sons are said to have landed at a place called Cymensora and fought against the local Britons. The chronicle goes on to report a victory in 491, at present day Pevensey, where the battle ended with the Saxons slaughtering their opponents to the last man. Ælle was the first king recorded by the 8th century chronicler Bede to have held "imperium", or overlordship, over other Anglo-Saxon kingdoms. In the late 9th-century "Anglo-Saxon Chronicle" (around four hundred years after his time) Ælle is recorded as being the first bretwalda, or "Britain-ruler", though there is no evidence that this was a contemporary title. Ælle's death is not recorded and although he may have been the founder of a South Saxon dynasty, there is no firm evidence linking him with later South Saxon rulers. The 12th-century chronicler Henry of Huntingdon produced an enhanced version of the "Anglo-Saxon Chronicle" that included 514 as the date of Ælle's death, but this is not secure.
Historical context. Historians are divided on the detail of Ælle's life and existence as it was during the least-documented period in English history of the last two millennia. By the early 5th century, Britain had been Roman for over three hundred and fifty years. Amongst the enemies of Roman Britain were the Picts of central and northern Scotland, and the Gaels known as Scoti, who were raiders from Ireland. Also vexatious were the Saxons, the name Roman writers gave to the peoples who lived in the northern part of what is now Germany and the southern part of the Jutland peninsula. Saxon raids on the southern and eastern shores of England had been sufficiently alarming by the late 3rd century for the Romans to build the Saxon Shore forts, and subsequently to establish the role of the Count of the Saxon Shore to command the defence against these incursions. Roman control of Britain finally ended in the early part of the 5th century; the date usually given as marking the end of Roman Britain is 410, when the Emperor Honorius sent letters to the British, urging them to look to their own defence. Britain had been repeatedly stripped of troops to support usurpers' claims to the Roman empire, and after 410 the Roman armies never returned.
Sources for events after this date are extremely scarce, but a tradition, reported as early as the mid-6th century by a British priest named Gildas, records that the British sent for help against the barbarians to Aetius, a Roman consul, probably in the late 440s. No help came. Subsequently, a British leader named Vortigern is supposed to have invited continental mercenaries to help fight the Picts who were attacking from the north. The leaders, whose names are recorded as Hengest and Horsa, rebelled, and a long period of warfare ensued. The invaders—Angles, Saxons, Jutes, and Frisians—gained control of parts of England, but lost a major battle at Mons Badonicus (the location of which is not known). Some authors have speculated that Ælle may have led the Saxon forces at this battle, while others reject the idea out of hand. The British thus gained a respite, and peace lasted at least until the time Gildas was writing: that is, for perhaps forty or fifty years, from around the end of the 5th century until midway through the sixth. Shortly after Gildas's time, the Anglo-Saxon advance was resumed, and by the late 6th century nearly all of southern England was under the control of the continental invaders.
Early sources. There are two early sources that mention Ælle by name. The earliest is "The Ecclesiastical History of the English People", a history of the English church written in 731 by Bede, a Northumbrian monk. Bede mentions Ælle as one of the Anglo-Saxon kings who exercised what he calls "imperium" over "all the provinces south of the river Humber"; "imperium" is usually translated as "overlordship". Bede gives a list of seven kings who held "imperium", and Ælle is the first of them. The other information Bede gives is that Ælle was not a Christian—Bede mentions a later king, Æthelberht, as "the first to enter the kingdom of heaven". The second source is the "Anglo-Saxon Chronicle", a collection of annals assembled in the Kingdom of Wessex in c. 890, during the reign of Alfred the Great. The "Chronicle" has three entries for Ælle, from 477 to 491, as follows: The "Chronicle" was put together about four hundred years after these events. It is known that the annalists used material from earlier chronicles, as well as from oral sources such as sagas, but there is no way to tell where these lines came from. The terms 'British' and 'Welsh' were used interchangeably, as 'Welsh' is the Saxon word meaning 'foreigner', and was applied to all the native Romano-British of the era.
Three of the places named may be identified: The "Chronicle" mentions Ælle once more under the year 827, where he is listed as the first of the eight "bretwaldas", or "Britain-rulers". The list consists of Bede's original seven, plus Egbert of Wessex. There has been much scholarly debate over just what it meant to be a "bretwalda", and the extent of Ælle's actual power in southern England is an open question. It is also noteworthy that there is a long gap between Ælle and the second king on Bede's list, Ceawlin of Wessex, whose reign began in the late 6th century; this may indicate a period in which Anglo-Saxon dominance was interrupted in some way. Earlier sources than Bede exist which mention the South Saxons, though they do not name Ælle. The earliest reference is still quite late, however, at about 692: a charter of King Nothhelm's, which styles him "King of the South Saxons". Charters are documents which granted land to followers or to churchmen, and which would be witnessed by the kings who had power to grant the land. They are one of the key documentary sources for Anglo-Saxon history, but no original charters survive from earlier than 679.
There are other early writers whose works can shed light on Ælle's time, though they do not mention either him or his kingdom. Gildas's description of the state of Britain in his time is useful for understanding the ebb and flow of the Anglo-Saxon incursions. Procopius, a Byzantine historian, writing not long after Gildas, adds to the meagre sources on population movement by including a chapter on England in one of his works. He records that the peoples of Britain—he names the English, the British, and the Frisians—were so numerous that they were migrating to the kingdom of the Franks in great numbers every year, although this is probably a reference to Britons emigrating to Armorica to escape the Anglo-Saxons. They subsequently gave their name to the area they settled as Brittany, or "la petite Bretagne" (lit., "little Britain"). Evidence from place names in Sussex. The early dates given in the "Anglo-Saxon Chronicle" for the colonization of Sussex are supported by an analysis of the place names of the region. The strongest evidence comes from place names that end in "-ing", such as Worthing and Angmering. These are known to derive from an earlier form ending in "-ingas". "Hastings" for example, derives from "Hæstingas" which may mean "the followers or dependents of a person named Hæsta", although others suggest the heavily Romanised region may have had names of Gallo-Roman origin derived from "-ienses". From west of Selsey Bill to east of Pevensey can be found the densest concentration of these names anywhere in Britain. There are a total of about forty-five place names in Sussex of this form, but personal names either were not associated with these places or fell out of use.
The preservation of Ælle's sons in Old English place names is unusual. The names of the founders, in other origin legends, seem to have British or Latin roots not Old English. It is likely that the foundation stories were actually known before the 9th century, but the annalists manipulated them to provide a common origin for the new regime. The origin stories purported that the British were defeated and replaced by invading Anglo-Saxons arriving in small ships. These stories were largely believed right up to the 19th century, but are now regarded as myths. Reign. If the dates given by the "Anglo-Saxon Chronicle" are accurate to within half a century, then Ælle's reign lies in the middle of the Anglo-Saxon expansion, and prior to the final conquest of the Britons. It also seems consistent with the dates given to assume that Ælle's battles predate Mons Badonicus.This in turn would explain the long gap, of fifty or more years, in the succession of the "bretwaldas": if the peace gained by the Britons did indeed hold till the second half of the 6th century, it is not to be expected that an Anglo-Saxon leader should have anything resembling overlordship of England during that time. The idea of a pause in the Anglo-Saxon advance is also supported by the account in Procopius of 6th century migration from Britain to the kingdom of the Franks. Procopius's account is consistent with what is known to be a contemporary colonization of Armorica (now Brittany, in France); the settlers appear to have been at least partly from Dumnonia (modern Cornwall), and the area acquired regions known as Dumnonée and Cornouaille. It seems likely that something at that time was interrupting the general flow of the Anglo-Saxons from the continent to Britain.
The dates for Ælle's battles are also reasonably consistent with what is known of events in the kingdom of the Franks at that time. Clovis I united the Franks into a single kingdom during the 480s and afterwards, and the Franks' ability to exercise power along the southern coast of the English channel may have diverted Saxon adventurers to England rather than the continent. It is possible, therefore, that a historical king named Ælle existed, who arrived from the continent in the late 5th century, and who conquered much of what is now Sussex. He may have been a prominent war chief with a leadership role in a federation of Anglo-Saxon groups fighting for territory in Britain at that time. This may be the origin of the reputation that led Bede to list him as holding overlordship over southern Britain. The battles listed in the "Chronicle" are compatible with a conquest of Sussex from west to east, against British resistance stiff enough to last fourteen years. His area of military control may have extended as far as Hampshire and north to the upper Thames valley, but it certainly did not extend across all of England south of the Humber, as Bede asserts.
The historian Guy Halsall argues that as Ælle immediately preceded a sequence of three contemporaries from the late sixth-century in Bede's original list (Ceawlin of Wessex, Æthelberht of Kent, and Rædwald of East Anglia), it is far more likely that Ælle dates to the mid sixth century, and that the "Chronicle" has moved his dates back a century in order to provide a foundation myth for Sussex which puts it chronologically and geographically between the origins of the kingdoms of Kent and Wessex. Death and burial. Ælle's death is not recorded by the "Chronicle", which gives no information about him, or his sons, or the South Saxons until 675, when the South Saxon king Æthelwalh was baptized. It has been conjectured that, as Saxon war leader, Ælle may have met his death in the disastrous battle of Mount Badon when the Britons halted Saxon expansion. If Ælle died within the borders of his own kingdom then it may well have been that he was buried on Highdown Hill with his weapons and ornaments in the usual mode of burial among the South Saxons. Highdown Hill is the traditional burial-place of the kings of Sussex.
Atari Atari () is a brand name that has been owned by several entities since its inception in 1972. It is currently owned by French holding company Atari SA (formerly Infogrames) and its focus is on "video games, consumer hardware, licensing and blockchain". The original Atari, Inc., founded in Sunnyvale, California, United States in 1972 by Nolan Bushnell and Ted Dabney, was a pioneer in arcade games, home video game consoles, and home computers. The company's products, such as "Pong" and the Atari 2600, helped define the electronic entertainment industry from the 1970s to the mid-1980s. In 1984, as a result of the video game crash of 1983, the assets of the home console and computer divisions of the original Atari Inc. were sold off to Jack Tramiel's Tramel Technology Ltd., which then renamed itself to Atari Corporation, while the remaining part of Atari, Inc. was renamed Atari Games Inc. In early 1985, Warner established a new corporation jointly with Namco subsequently named Atari Games Corporation, which took control of Atari's coin-operated games division. The rights to Atari, Inc.'s game properties were shared between the two companies: Atari Corporation receiving the trademarks and the home rights, while Atari Games receiving the rights to use the logo and brand name with appended text "Games" on arcade products. In 1996, Atari Corporation reverse-merged with disk-drive manufacturer JT Storage (JTS) and effectively perished. In 1998, Hasbro Interactive, part of the toy company Hasbro, acquired all Atari Corporation–related properties from JTS, as part of a subsidiary which it then renamed to Atari Interactive. Meanwhile, Atari Games was acquired by Midway Games in 1996, and effectively retired the Atari name on arcades by 2000 to avoid public confusion with Hasbro's Atari home releases.
Infogrames Entertainment (IESA) – precursor of the present-day Atari SA – became the new owner of the Atari brand after buying Hasbro Interactive in 2001, renaming it Infogrames Interactive, which intermittently published Atari-branded home titles. In 2003, it renamed the division Atari Interactive. Another IESA division called Infogrames Inc., which was founded as GT Interactive, changed its name to Atari, Inc. the same year, licensing the Atari name and logo from its fellow subsidiary. In 2008, IESA completed its acquisition of Atari, Inc.'s outstanding stock, making it a wholly owned subsidiary. IESA renamed itself Atari SA in 2009 which remains the status quo. It sought bankruptcy protection under French law in 2013. On the other hand, Atari's post-1984 arcade titles are the property of Warner Bros. Games since receiving the assets following Midway's bankruptcy in 2009. History. Logotype. The name comes from the Japanese term "atari", used while playing the ancient board game Go. The word "atari" means "to hit a target" in Japanese; in Go, it indicates a situation where a player will be able to capture one or more stones of the opponent in the next move.
The Atari logo was designed by George Opperman, who was Atari's first in-house graphic designer, and drawn by Evelyn Seto. The design is known as "Fuji" for its resemblance to the Japanese mountain, although the logo's origins are unrelated to it. Opperman designed the logo intending for the silhouette to look like the letter A as in Atari and for its three "prongs" to resemble players and the midline of the "court" in the company's first hit game, "Pong". Atari Inc. (1972–1984). In 1971, Nolan Bushnell and Ted Dabney founded a small engineering company, Syzygy Engineering, that designed "Computer Space", the world's first commercially available arcade video game, for Nutting Associates. On June 27, 1972, the two incorporated Atari, Inc. and soon hired Al Alcorn as their first design engineer. Bushnell asked Alcorn to produce an arcade version of the Magnavox Odyssey's Tennis game, which would be named "Pong". Before Atari's incorporation, Bushnell considered various terms from the game "Go", eventually choosing "atari", referencing a position in the game when a group of stones is imminently in danger of being taken by one's opponent. Atari was incorporated in the state of California on June 27, 1972.
In 1973, Atari secretly spawned a competitor called Kee Games, headed by Nolan's next-door neighbor Joe Keenan, to circumvent pinball distributors' insistence on exclusive distribution deals; both Atari and Kee could market nearly the same game to different distributors, each getting an "exclusive" deal. Joe Keenan's management of the subsidiary led to his appointment as president of Atari when Kee was absorbed into the company in 1974. In 1975, Atari's Grass Valley, California subsidiary Cyan Engineering started the development of a flexible console that was capable of playing the four existing Atari games. The result was the Atari Video Computer System, or VCS (later renamed 2600 when the 5200 was released). The introductory price of $199 () included a console, two joysticks, a pair of paddles, and the "Combat" game cartridge. Bushnell knew he had another potential hit on his hands but bringing the machine to market would be extremely expensive. Looking for outside investors, Bushnell sold Atari to Warner Communications in 1976 for $28 million. Nolan continued to have disagreements with Warner Management over the direction of the company, the discontinuation of the pinball division, and most importantly, the notion of discontinuing the 2600. In December 1978, Bushnell was fired as chairman and co-CEO following an argument with Manny Gerard. He decided to leave the company rather than take an advisory role.
The development of a successor to the 2600 started as soon as it shipped. The original team estimated the 2600 had a lifespan of about three years; it then set forth to build the most powerful machine possible within that time frame. Mid-way into their effort the home computer revolution took off, leading to the addition of a keyboard and features to produce the Atari 800 and its smaller sibling, the 400. The new machines had some success when they finally became available in quantity in 1980. From this platform Atari released their next-generation game console in 1982, the Atari 5200. It was unsuccessful due to incompatibility with the 2600 game library, a small quantity of dedicated games, and notoriously unreliable controllers. Porting arcade games to home systems with inferior hardware was difficult. The ported version of "Pac-Man" for Atari 2600 omitted many of the visual features of the original to compensate for the lack of ROM space and the hardware struggled when multiple ghosts appeared on the screen creating a flickering effect.
Under Warner and Atari's chairman and CEO, Raymond Kassar, the company achieved its greatest success, selling millions of 2600s and computers. At its peak, Atari accounted for a third of Warner's annual income and was the fastest-growing company in US history at the time. It ran into problems in the early 1980s. Faced with fierce competition and price wars in the game console and home computer markets, Atari was never able to duplicate the success of the 2600. These problems were followed by the video game crash of 1983, with losses that totaled more than $500 million. Warner's stock price slid from $60 to $20, and the company began searching for a buyer for its troubled division. In 1983, Ray Kassar resigned. Financial problems continued to mount and Kassar's successor, James J. Morgan, had less than a year in which to tackle the company's problems. He began a massive restructuring of the company and worked with Warner Communications in May 1984 to create "NATCO" (an acronym for New Atari Company). NATCO further streamlined the company's facilities, personnel, and spending. Unknown to James Morgan and the senior management of Atari, Warner had been in talks with Tramel Technology to buy assets pertaining to Atari's consumer electronics and home computer businesses. Negotiating until close to midnight on July 1, 1984, Jack Tramiel completed the asset purchase for $240 million in promissory notes and stocks. Warner gained a 20% stake in Tramel Technology, which was renamed Atari Corporation. Warner also sold the Ataritel division to Mitsubishi.
Atari Corporation (1984–1996). Under Tramiel's ownership, Atari Corp. used the remaining stock of game console inventory to keep the company afloat while they finished development on a 16/32-bit computer system, the Atari ST. ("ST" stands for "sixteen/thirty-two", referring to the machines' 16-bit bus and 32-bit processor core.) In April 1985, they released an update to the 8-bit computer line, the Atari 65XE, the first in the Atari XE series. June 1985 saw the release of the Atari 130XE; Atari User Groups received early sneak-preview samples of the new Atari 520ST's, and major retailer shipments hit store shelves in September 1985 of Atari's new 32-bit Atari ST computers. In 1986, Atari launched two consoles designed under Warner — the Atari 2600jr and the Atari 7800 console (which saw limited release in 1984). Atari rebounded, earning a $25 million profit that year. In 1987, Atari acquired the Federated Group for $67.3 million, securing shelf space in over 60 stores in California, Arizona, Texas and Kansas at a time when major American electronics outlets were reluctant to carry Atari-branded computers, and two-thirds of Atari's PC production was sold in Europe. The Federated Group (not related to Federated Department Stores) was sold to Silo in 1989.
In 1988, the company unveiled the 1040STF and the Mega ST with a bit image manipulator chip, and launched its first parallel computer. The ATW-800 Transputer was based on the Inmos T800 CPU, which had a 32/64-bit architecture, ran at 15 million instructions per second (MIPS) and housed a Charity videochip that supported 16 million colors. The company continued to experiment with parallel computing aiming at B2B customers and graphic designers, but the transputer line failed to achieve commercial success. In 1989, Atari released the Atari Lynx, the first ever handheld console with a color display and a backlit screen, to much fanfare. A shortage of parts kept the system from being released nationwide for the 1989 Christmas season, and the Lynx lost market share to Nintendo's Game Boy, which, despite only having a black and white display, was cheaper, had better battery life and had much higher availability. Tramiel emphasized computers over game consoles, but Atari's proprietary computer architecture and operating system fell victim to the success of the Wintel platform while the game market revived. In 1989, Atari Corp. sued Nintendo for $250 million, alleging it had an illegal monopoly. Atari eventually lost the case when it was rejected by a US district court in 1992.
In 1991, Atari released its PCs ABC386SXII and ABC386DXII based on Intel's i386 chip. In 1993, Atari positioned its Jaguar as the only 64-bit interactive media entertainment system available, but it sold poorly. It would be the last home console to be produced by Atari and the last to be produced by an American manufacturer until Microsoft's introduction of the Xbox in 2001. By 1996, a series of successful lawsuits had left Atari with millions of dollars in the bank, but the failure of the Lynx and Jaguar left Atari without a product to sell. Tramiel and his family also wanted out of the business. The result was a rapid succession of changes in ownership. In July 1996, Atari merged with JTS Inc., a short-lived maker of hard disk drives, to form JTS Corp. Atari's role in the new company largely became that of holder for the Atari properties and minor support, and consequently the name largely disappeared from the market. Video game magazines reported it as Atari exiting the video game business. Atari Games Corporation (1985–1999).
After the asset sale to Tramel Technology, Atari was renamed Atari Games, Inc. In 1985, Warner established a new corporation called AT Games, Inc. with Namco, which purchased a controlling interest in the new venture. Warner then transferred the coin-operated games division of Atari Games, Inc. to AT Games, Inc., which renamed itself Atari Games Corporation. Warner renamed Atari Games, Inc. to Atari Holdings, which continued as a nonoperating subsidiary until 1992. In 1987, Namco sold 33% of its shares to a group of employees led by then-president Hideyuki Nakajima. He had been the president of Atari Games since 1985. Atari Ireland was a subsidiary of Atari Games that manufactured their games for the European market. Atari Games continued to manufacture arcade games and units, and starting in 1988, also sold cartridges for the Nintendo Entertainment System under the Tengen brand name, including a version of "Tetris". The companies exchanged a number of lawsuits in the late 1980s related to disputes over the rights to "Tetris" and Tengen's circumvention of Nintendo's lockout chip, which prevented third parties from creating unauthorized games. The suit finally reached a settlement in 1994, with Atari Games paying Nintendo cash damages and the use of several patent licenses.
In April 1996, after an unsuccessful bid by Atari cofounder Nolan Bushnell, the company was sold to WMS Industries, owners of the Williams, Bally, and Midway arcade brands, which restored the use of the Atari Games name. On November 19, 1999, Atari Games Corporation was renamed Midway Games West Inc., resulting in the Atari Games name no longer being used, with "San Francisco Rush 2049" being the final Atari-branded arcade release. Hasbro Interactive (1998–2000). On March 13, 1998, JTS sold the Atari name and assets to Hasbro Interactive for $5 million. This transaction primarily involved the brand and intellectual property, which now fell under the Atari Interactive division of Hasbro Interactive. Two years after Atari's "death", the brand made a comeback with Hasbro immediately stating the development of new remakes of Atari classics, starting with "Centipede" released on Windows PCs later that year. The brand name changed hands again in December 2000 when French software publisher Infogrames took over Hasbro Interactive.
Infogrames and Atari SA (2001–present). In October 2001, Infogrames Entertainment SA (IESA, now Atari SA) announced that it was "reinventing" the Atari brand with the launch of three new games featuring a prominent Atari branding on their boxarts: "Splashdown", "MX Rider" and "TransWorld Surf". Infogrames used Atari as a brand name for games aimed at 18–34 year olds. Other Infogrames games under the Atari name included "V-Rally 3", "Neverwinter Nights", "Stuntman" and "Enter the Matrix". On May 8, 2003, IESA had its majority-owned but discrete US subsidiary Infogrames, Inc. officially renamed Atari, Inc., renamed its European operations to Atari Europe but kept the original name of the main company Infogrames Entertainment. The original Atari holdings division purchased from Hasbro, originally Hasbro Interactive and later Infogrames Interactive, was renamed Atari Interactive. Atari, Inc. buyout and name change to Atari SA. On March 6, 2008, IESA made an offer to Atari, Inc. to buy out all remaining public shares for a value of $1.68 per share, or $11 million total. The offer would make IESA sole owner of Atari, Inc., thus making it a privately held company. On April 30, 2008, Atari, Inc. announced its intentions to accept Infogrames' buyout offer and to merge with Infogrames. On October 8, 2008, IESA completed its acquisition of Atari, Inc., making it a wholly owned subsidiary.
On December 9, 2008, Atari announced that it had acquired Cryptic Studios, an MMORPG developer. Namco Bandai purchased a 34% stake in Atari Europe on May 14, 2009, paving the way for its acquisition from IESA. Atari had significant financial issues for several years prior, with losses in the tens of millions since 2005. In May 2009, Infogrames Entertainment SA, the parent company of Atari, and Atari Interactive, announced it would change its name to Atari SA. In April 2010, Atari SA board member and former CEO David Gardner resigned. Original Atari co-founder Nolan Bushnell joined the board as a representative for Blubay holdings. As of March 31, 2011, the board of directors consisted of Frank Dangeard, Jim Wilson, Tom Virden, Gene Davis and Alexandra Fichelson. On January 21, 2013, the four related companies Atari, Atari Interactive, Humongous, and California US Holdings filed for Chapter 11 bankruptcy in the United States Bankruptcy Court for the Southern District of New York. All three Ataris emerged from bankruptcy one year later and the entering of the social casino gaming industry with Atari Casino. Frederic Chesnais, who now heads all three companies, stated that their entire operations consist of a staff of 10 people.
Chesnais era (2013–2021). On June 22, 2014, Atari announced a new corporate strategy that would include a focus on "new audiences", specifically "LGBT, social casinos, real-money gambling, and YouTube". On June 8, 2017, a short teaser video was released, promoting a new product; and the following week Chesnais confirmed the company was developing a new game console – the hardware was stated to be based on PC technology, and still under development. In mid July 2017 an Atari press release confirmed the existence of the aforementioned new hardware, referred to as the "Ataribox". The box design was derived from early Atari designs (e.g. 2600) with a ribbed top surface, and a rise at the back of the console; two versions were announced: one with a traditional wood veneer front, and the other with a glass front. Connectivity options were revealed, including HDMI, USB (x4), and SD card – the console was said to support both classic and current games. Also, according to an official company statement of June 22, 2017, the product was to be initially launched via a crowdfunding campaign in order to minimize any financial risk to the parent company.
On September 26, 2017, Atari sent out a press release about the new "Atari VCS", which confirmed more details about the console. It runs a Linux operating system, with full access to the underlying OS, but it has a custom interface designed for the TV. On January 27, 2020, Atari announced a deal with GSD Group to build Atari Hotels, with the first breaking ground in Phoenix in mid-2020. Additional hotels were also planned in Las Vegas, Denver, Chicago, Austin, Seattle, San Francisco, and San Jose. The company plans to make the hotel experience immersive and accessible to all ages. Hotels are planned to include virtual and augmented reality technologies. On December 16, 2020, Atari shipped the first units of the Atari VCS exclusive to backers of the systems crowdfunding campaign. Atari urged the backers to give feedback on the system so that the company could make changes to improve the product on its official launch. The consoles only ship to North America, Australia, and New Zealand. In 2020, Atari launched its decentralized cryptocurrency Atari Token in equal partnership with the ICICB Group. Atari Group announced in March 2020 that it granted ICICB a non-exclusive license to run a cryptocurrency online casino on Atari's website, based on the Atari Token. The group partnering with Atari opened a new company in Gibraltar called Atari Chain LTD. In March 2021, Atari extended its partnership with ICICB Group for the development of Atari branded hotels, and the first hotels will be constructed at selected locations outside the United States, with Dubai, Gibraltar and Spain.
Rosen era (2021–present). In late 2021, Wade Rosen became the new CEO of Atari. Unlike his predecessor, Rosen's strategy for Atari is a re-focus on retro gaming and Atari's classic franchises. On 18 April 2022, Atari announced the termination of all license agreements with ICICB Group and its subsidiaries ("ICICB"). The license agreements between Atari and ICICB, including the Atari Chain Limited license (the "Joint Venture") and the related licenses including hotel and casino licenses, have been terminated effective 18 April 2022. ICICB is not authorized to represent Atari or its brands in any manner. In March 2024, Atari announced that it will work with coin-op manufacturer Alan-1 to bring "Atari Recharged" titles on arcades. This would mark the return of the Atari brand in the arcade space after 25 years, when "San Francisco Rush 2049" was released.
Afghans Afghans (; ) are the citizens and nationals of Afghanistan, as well as their descendants in the Afghan diaspora. The country is made up of various ethnic groups, of which Pashtuns, Tajiks, Hazaras, and Uzbeks are the largest. The three main languages spoken among the Afghan people are Dari, Pashto, and Uzbek. Historically, the term "Afghan" was a Pashtun ethnonym, but later came to refer to all people in the country, regardless of their ethnicity. Etymology. The earliest mention of the name "Afghan" ("Abgân") is by Shapur I of the Sassanid Empire during the 3rd century CE, In the 4th century, the word "Afghans/Afghana" (αβγανανο) as reference to the Pashtun people is mentioned in the Bactrian documents found in Northern Afghanistan. The word 'Afghan' is of Persian origin and refers to the Pashtun people. Some scholars suggest that the word "Afghan" is derived from the words "awajan/apajan" in Avestan and "ava-Han/apa-Han" in Sanskrit, which means "killing, striking, throwing and resisting, or defending." Under the Sasanians, and possibly the Parthian Empire, the word was used to refer to men of a certain Persian sect. In the past, several scholars sought a connection with "horse", Skt.aśva-, Av.aspa-, i.e. the Aśvaka or Aśvakayana, the name of the "Aśvakan" or "Assakan", the ancient inhabitants of the Hindu Kush region. Some have theorized that the name of the "Aśvakan" or "Assakan" has been preserved in that of the modern Pashtun, with the name Afghan being derived from Asvakan.
As an adjective, the word Afghan also means "of or relating to Afghanistan or its people, language or culture". According to the 1964 Constitution of Afghanistan, all Afghans citizens are equal in rights and obligations before the law. The fourth article of the Constitution of the Islamic Republic of Afghanistan, which was valid until 2021, states that citizens of Afghanistan consist of Pashtun, Tajik, Uzbek, Turkmen, Baloch, Pashayi, Nuristani, Aimaq, Arab, Kyrgyz, Qizilbash, Gurjar, Brahui, and members of other ethnicities. There are political disputes regarding this: there are members of the non-Pashtun ethnicities of Afghanistan that reject the term Afghan being applied to them, and there are Pashtuns in Pakistan that wish to have the term Afghan applied to them. Usage as an ethnonym. The pre-nation state, historical ethnonym Afghan was used to refer to a member of the Pashtun ethnic group. Due to the changing political nature of the state, the meaning has changed, and the term has shifted to refer to the national identity of people from Afghanistan of all ethnicities.
From a more limited, ethnological point of view, "Afḡhān" is the term by which the Persian-speakers of Afghanistan (and the non-Pashtō-speaking ethnic groups generally) designate the Pashtūn. The equation Afghans = Pashtūn has been propagated all the more, both in and beyond Afghanistan, because the Pashtūn tribal confederation has maintained its hegemony in the country, numerically and politically. Variations. The term "Afghani" refers to the unit of Afghan currency. The term is also often used in the English language (and appears in some dictionaries) for a person or thing related to Afghanistan, although some have expressed the opinion that this usage is incorrect. The reason for this usage might be because the term "Afghani" (افغانی) is in fact a valid demonym for Afghans in the overall Persian language, whereas "Afghan" is derived from Pashto. Thus, "Afghan" is the anglicized form of "Afghani" when translating from Dari Persian, but not from Pashto. Another variant is "Afghanese", which has been seldom used in place of Afghan.
Ethnicities. Afghans come from various ethnic backgrounds. The largest ethnic groups are Pashtuns, Tajiks, Hazaras, and Uzbeks, who make up approximately 95% of the population of Afghanistan. They are of diverse origins including of Iranic, Turkic or Mongolic ethnolinguistic roots. Religions. The Afghan people of all ethnicities are predominantly and traditionally followers of Islam, of whom around 90% are of Sunni and 10% the Shia branch. Other religious minorities include the Afghan Hindus, Afghan Sikhs, Afghan Zoroastrians, Afghan Jews and Afghan Christians. Culture. Afghan culture has existed for over three millennia, dating back to the time of the Achaemenid Empire in 500 BCE. Afghans have both common cultural features and those that differ between regions with each of the 34 provinces having its own unique distinctive cultures partly as a result of geographic obstacles that divide the country. Afghanistan's culture is historically linked to nearby Persia, including both countries following the Islamic religion, the Solar Hijri calendar and speaking similar languages, this is due to Iran and Afghanistan being culturally close to each other for thousands of years.
Acadia University Acadia University is a public, predominantly undergraduate university located in Wolfville, Nova Scotia, Canada, with some graduate programs at the master's level and one at the doctoral level. The enabling legislation consists of the Acadia University Act and the Amended Acadia University Act 2000. The Wolfville Campus houses Acadia University Archives and the Acadia University Art Gallery. Acadia offers over 200 degree combinations in the faculties of arts, pure and applied science, professional studies, and theology. The student-faculty ratio is 15:1 and the average class size is 28. Open Acadia offers correspondence and distance education courses. Acadia does have Botanical Gardens known as the Harriet Irving Gardens. These gardens feature plants and trees native to the Acadian forest region. History. Acadia began as an extension of Horton Academy in 1828, which was founded in Horton, Nova Scotia, by Baptists from Nova Scotia and Queen's College in 1838, who will be gathered into the Canadian Baptists of Atlantic Canada (Canadian Baptist Ministries). It was designed to prepare men for the ministry and to supply education for lay members.
In 1838, the Nova Scotia Baptist Education Society founded Queen's College (named for Queen Victoria). The college began with 21 students in January 1839. The name "Queen's College" was denied to the Baptist school, so it was renamed "Acadia College" in 1841, in reference to the history of the area as an Acadian settlement. Acadia College awarded its first degrees in 1843 and became Acadia University in 1891, established by the Acadia University Act. The Granville Street Baptist Church (now First Baptist Church Halifax) has played a supporting role throughout its history. Many individuals who have made significant contributions to Acadia University, including the first president John Pryor, were members of the First Baptist Church Halifax congregation. In 1851, the power of appointing governors was transferred from the Nova Scotia Baptist Education Society to the Baptist Convention of the Maritime Provinces. Charles Osborne Wickenden, an architect, and J.C. Dumaresq designed the Central Building, Acadia College, 1878–79.
Clara Belle Marshall, from Mount Hanley, Nova Scotia, became the first woman to graduate from Acadia University in 1879. In 1891, there were changes in the Act of Incorporation. Andrew R. Cobb designed several campus buildings including: Raynor Hall Residence, 1916; and Horton House, designed by Cobb in the Georgian style, and built by James Reid of Yarmouth, Nova Scotia, which was opened in 1915 as Horton Academy. Today, Horton Hall is the home of the Department of Psychology and Research and Graduate Studies. In 1967 Emmerson Hall was converted to classrooms and offices for the School of Education. It is a registered Heritage Property. Unveiled on 16 August 1963, a wooden and metal organ in Manning Chapel, Acadia University, is dedicated to Acadia University's war dead of the First and Second World Wars and the Korean War. A book of remembrance in Manning Chapel, Acadia University was unveiled on 1 March 1998 through the efforts of the Wolfville Historical Society. In 1966, it terminated its affiliation with the Canadian Baptists of Atlantic Canada (Canadian Baptist Ministries). The denomination maintains nine seats on the university's Board of Governors.
Acadia is a laureate of Washington's Smithsonian Institution and a part of the permanent research collection of the National Museum of American History. Acadia is also the only Canadian university selected for inclusion in the Education and Academia category of the Computerworld Smithsonian Award. Faculty strikes. Acadia University's Board of Governors and members of the Acadia University Faculty Association (AUFA) have ratified a new collective agreement covering the period 1 July 2010 to 30 June 2014. The faculty of Acadia University have been on strike three times in the history of the institution. The first was 24 February to 12 March 2004. The second was 15 October to 5 November 2007. The second strike was resolved after the province's labour minister, Mark Parent, appointed a mediator, on 1 November, to facilitate an agreement. The third strike began on 1 February 2022 and ended 1 March 2022 with both sides agreeing to binding arbitration. Academics. Rankings. In "Maclean's" 2023 Guide to Canadian Universities, Acadia was ranked fifth in the publication's "primarily undergraduate" Canadian university category, tied with Bishop's University. In the same year, the publication ranked Acadia 33rd, in Maclean's reputation survey.
