everywhere – for people who can truly see and think. people can only achieve happiness and enjoy what they experience through faith and love of allah. of course allah, who creates the delights of this world as a blessing, will bestow most of the beauty and joy of these blessings on those who love him most and who are closest to him. since unbelievers forget that it is allah who bestows blessings and pleasures, they imagine they can attain happiness by living irresponsibly and without restraint. but the fact is that living heedless of allah, in an unrestrained and irresponsible manner, always inflicts stress, troubles and sorrows on them. blessings have always turned into afflictions and pleasures to be enjoyed have always ended in disappointment. since these people are unable to reflect on the beauty of being close to, and believing in, allah and since they fail to comprehend that allah bestows all blessings, they imagine they can succeed by the use of such false propaganda techniques. but the fact is that they cannot live pleasant and peaceful lives, and neither can they influence the people around them. ( the bus posters espoused by dawkins attracted a great deal of criticism in many countries. bus drivers in european countries such as finland boycotted them because of the extreme reactions they attracted, bus companies decided not to use the posters, and they were also torn up by members of the public. ) as a result, the posters in question were banned in many places. 180 ) another place where this conditioning is carried out on an intensive basis is schools. biology, a university text book, teaches students that in learning about the " nature of life " they must always bear in mind that " evolution is random and not designed ". 181 students reading the university text book life : the science of biology encounter the following passage : " darwinian world view " means accepting not only the processes of evolution, but also the view that... evolutionary change is not directed toward a final goal or state. " 182 there can be no doubt that an education system that teaches the lie that man came into being by chance, as the result of blind and unconscious coincidences means regarding the poisoning of young minds by ideas that encourage anarchy, conflict, slaughter and selfishness as legitimate, and people receiving such indoctrination can be directed as desired. for example, the error taught to students in douglas futuyma ' s text book evolutionary biology is this : futuyma ' s unscientific statement continues


, and people receiving such indoctrination can be directed as desired. for example, the error taught to students in douglas futuyma ' s text book evolutionary biology is this : futuyma ' s unscientific statement continues : but this is all a deception. human beings are not freed from their responsibilities by regarding everything as simple and unconscious. and it is impossible for a feeling of avoiding one ' s responsibilities to make people happy. once people cast off this feeling, they will not suddenly enjoy earthly pleasures or at once be freed from all their worries. there is a very important truth that atheists and darwinists either do not know, or refuse to admit : allah creates all things. it is also allah who creates blessings and pleasures in this world. and it is therefore allah who bestows the sensation of enjoying earthly pleasures and a pleasant life. if allah so wishes he can make a person suffer the worst unhappiness and torment in the midst of all blessings and in great plenty and abundance. no matter how much a person may strive to have unlimited enjoyment of all delights, it is still allah who bestows pleasure and happiness on him. one of atheists ' and darwinists ' gravest errors is that they ignore this reality. everyone who thinks he has no responsibilities is also searching for love, comfort and security, just like everyone else. but he will possess none of these in a society made up of individuals like himself. throughout his life, the irresponsible person tries to forget that he will one day die. but he is in fact constantly in the shadow of death. he sees the deaths of people around him and constantly witnesses sickness and accidents. even the death of an insect will remind him of the death he is trying to get away from. no matter how much he tries to deny the fact of death, the fear of it will eventually enfold his entire body. he grieves for people around him who die and, according to his own beliefs, just cease to exist. he begins to find it impossible to deny that his own body cannot withstand the ravages of time, and that death is drawing closer all the time. far from comforting him, denying the fact of death will bring with it fear, stress and worry. living irresponsibly in fact opens the door to all troubles and difficulties. a person who fails to properly appreciate that everything is under allah ' s control will be terrified of the future. a person who fails to appreciate that all profit and loss lies with


beyond that. ) the sole reason for the endeavor to prop up darwinism, put forth with the assumption that matter is the only absolute reality, and for all the deceptions and frauds perpetrated for that purpose, is to try to prevent acceptance of the fact that an almighty and sublime creator brought all things into being. darwinists have pursued that objective for the last 150 years and struggle hard to retain it. and that is the only reason for the adoption of darwinism as a false religion. but this fact is generally kept concealed, because for people to know it would prevent large masses of people from feeling any sympathy for darwinism. in particular, it will have a negative impact on people who believe in and respect allah. the fact that darwinism is a theory opposed to belief in allah attracted criticism from religious circles in darwin ' s time, and the theory was not easily adopted by people of the day. it began being adopted as a result of darwinist conditioning and propaganda. people who are currently taught in schools that human beings are descended from apes, and that dinosaurs grew wings and took to the air, generally imagine the theory of evolution to be a harmless one. they are unaware of the true face of the theory. they do not know that it is this perverse theory, devoid of any scientific foundation, that lies at the root of irreligion, dictatorial regimes, degeneration, terror and the martyrdom of so many troops in turkey. darwinists also try to conceal the true face of the theory they espouse. that is why they propagate the lie that darwinism is not incompatible with religion, in order to mislead the masses of people who believe in allah, to supposedly portray darwinism as harmless and to gain support from those people, as well. they believe that by these means they can win supporters and weaken the intellectual struggle against the theory of evolution. despite being exceedingly illogical and inconsistent, the lie of " evolutionary creation " they propagate to that end is secretly supported and raised by darwinists at every available opportunity. to that end they even resort to the deception that darwin was himself a devout religious believer. the atheist and darwinist richard dawkins admits the existence of a darwinist lobby serving that very purpose as follows : but the fact is that evolution is in no way compatible with religion. even though darwinists do not themselves believe in allah, and make a god out of chance ( surely allah is beyond that ), are totally opposed to the fact of creation and


: but the fact is that evolution is in no way compatible with religion. even though darwinists do not themselves believe in allah, and make a god out of chance ( surely allah is beyond that ), are totally opposed to the fact of creation and are engaged in a struggle against it, they suddenly become the greatest exponents of the false concept that allah created the universe through evolution. yet because of their blind devotion to materialism, darwinists never accept belief in allah. being a darwinist means rejecting belief in allah. the only reason why someone supports this pagan religion, devoid of any scientific evidence, that deifies chance, is to be able to deny the existence of allah ( surely allah is beyond that ). and there is nothing that darwinists will not do to turn people away from belief in allah. that is why people must always be on their guard against this deception! in his documentary expelled : " no intelligence allowed, " which explains how darwinism is a false religion based on indoctrination, the journalist larry witham makes the following statement : so even though darwinists definitively oppose belief in allah, they still play this unpleasant trick on people. but the people who believe in this nasty deception fail to consider the fact that almighty allah is certainly powerful enough to create all things by a variety of means. had he wished, our lord could have created living things by way of evolution. but he did not. all living things came into being on earth in a single moment, created from nothing. not a single verse of the qur ' an points to evolution. according to the qur ' an, the universe and all living things were created by allah commanding them to " be! " allah has revealed, with all the divine religions he has sent to man, that he created the entire universe, that he created it with a single command and that he creates in the form he wishes. indeed, when we look at the evidence on earth, we see that creation took place just as described in the qur ' an. the fossils of all life forms are perfect. they emerged suddenly, with perfect appearances, and never changed thereafter. living things never changed over millions of years. there is no chance of life emerging from inanimate matter. it is impossible for even a single protein to form spontaneously. the idea of extraordinarily complex life forms turning into one another is totally unscientific. there is no mechanism that can endow a life form with new, beneficial information. science has revealed with incontrovertible and


spontaneously. the idea of extraordinarily complex life forms turning into one another is totally unscientific. there is no mechanism that can endow a life form with new, beneficial information. science has revealed with incontrovertible and certain evidence that all living things possess a glorious complexity, right down to their proteins and even atoms, that they appeared in a single moment and that they never turned into one another. therefore, the idea that allah created through evolution is a monstrous lie, and part of the darwinist deception. ( for detailed information on the subject, see, harun yahya, why darwinism is imcompatible with the qur ' an ) everything created is evidence of allah ' s infinite might. allah tells us of this sublime creation in many verses of the qur ' an : [ allah is ] the originator of the heavens and earth. when he decides on something, he just says to it, ' be! ' and it is. ( surat al - baqara, 117 ) the likeness of ' isa in allah ' s sight is the same as adam. he created him from earth and then he said to him, ' be! ' and he was. ( surat al - ' imran, 59 ) it is he who created the heavens and the earth with truth. the day he says ' be! ' it is. his speech is truth. the kingdom will be his on the day the trumpet is blown, the knower of the unseen and the visible. he is the all - wise, the all - aware. ( surat al - an ' am, 73 ) our word to a thing when we desire it is just to say to it ' be! ' and it is. ( surat al - nahl, 40 ) does he who created the heavens and earth not have the power to create the same again? yes indeed! he is the creator, the all - knowing. his command when he desires a thing is just to say to it, ' be! ' and it is. ( surah ya sin, 81 - 82 ) modern - day science shows the invalidity of the materialist - evolutionist claim. contrary to what the theory of evolution maintains, the evidence of every piece of creation that surrounds us proves that there is no room for chance in the universe. if any evidence were found on earth that allah uses evolution as his instrument in creating, and if allah had revealed such a thing in the qur ' an, then people would of course at once


proves that there is no room for chance in the universe. if any evidence were found on earth that allah uses evolution as his instrument in creating, and if allah had revealed such a thing in the qur ' an, then people would of course at once sign up to and espouse the idea that " our lord created through evolution. " but allah reveals in the qur ' an that he creates with the command " be! " and there are no verses suggestive of creation through evolution. moreover, there is most definitely not a single piece of scientific evidence for evolution. the facts are therefore clear. every detail emerging from an investigation of the earth and sky, and all living things, is proof of the great might and power of allah. all living things came into being from nothing at our almighty lord allah ' s command. allah certainly has no need of natural causes in order to create. ( surely allah is beyond that. ) this is the most important point that darwinists need to grasp. allah reveals in one verse that : what about the one who argued with ibrahim about his lord, on the basis that allah had given him sovereignty? ibrahim said, ' my lord is he who gives life and causes to die. ' he said, ' i too give life and cause to die. ' ibrahim said, ' allah makes the sun come from the east. make it come from the west. ' and the one who was an unbeliever was dumbfounded. allah does not guide wrongdoing people. ( surat al - baqara, 258 ) those who seek to suggest that allah creates through evolution also have to account for how the djinn and angels were created. these people are silent when the issue of the creation of the djinn and angels is raised. allah reveals the creation of djinn and angels in verses : we created mankind out of dried clay formed from fetid black mud. we created the jinn before out of the fire of a searing wind. ( surat al - hijr, 26 - 27 ) praise be to allah, the bringer into being of the heavens and earth, he who made the angels messengers, with wings – two, three or four. he adds to creation in any way he wills. allah has power over all things. ( surah fatir, 1 ) those who maintain that man and living things came into being through evolution are of course unable to account for angels, created from light, and djinn, created from fire, in terms of evolution. for people who fail


fully grown ; and when i taught you the book and wisdom, and the torah and the gospel ; and when you created a bird - shape out of clay by my permission, and then breathed into it and it became a bird by my permission ; and healed the blind and the leper by my permission ; and when you brought forth the dead by my permission ; and when i held back the tribe of israel from you... " ( surat al - ma ' ida, 110 ) the bird made from clay by the prophet jesus ( pbuh ) suddenly, by allah ' s leave and at his choosing, turned into a living, fully formed and flawless bird with wings, capable of flying, reproducing and feeding. this creation from nothing is a great miracle that darwinists can never account. and it is also proof that all living things on earth are created. all this reveals a manifest reality. darwinists, who claim that evolution does not conflict with belief in allah, are trying to inflict a huge deception on devout believers and are seeking to take improper advantage of their faith. darwinism is one of the greatest dangers to, and opponents of, belief in allah today. darwinism is the most wide - ranging and effective snare of the dajjal, who is engaged in a direct campaign against faith in allah. true believers in allah must realize this danger and engage in intensive intellectual activities against it. supporting this danger by regarding it as harmless merely strengthens it and supports a perilous movement engaged in a struggle against belief in allah. it must not be forgotten that darwinism is a false and perverse pagan religion whose sole aim is to lead people to irreligion. 177 michael j. behe, darwin ' s black box : the biochemical challenge to evolution, free press, p. 233 178 jonathan wells, the icons of evolution, january 2003, p. 202 179 ibid., p. 209 181 miller and levine, biology 182 pirves, orians, heller ve sadava, life : the science of biology 183 jonathan wells, the icons of evolution, january 2003, pp. 190 - 191 184 ben stein, expelled " no intelligence allowed ", 2008


the synthesis of peroxisomes have been identified in humans. these genes are called pex genes, and the proteins they code for are called peroxins. disorders caused by abnormalities of peroxin proteins are often called " peroxisomal biogenesis " disorders. the pex7 gene codes for a peroxisomal component that helps transport other important proteins into the peroxisome. the proteins to be transported contain a signal, called " pts2 " ( peroxisome targeting sequence 2 ) that is recognized by the receptor on the peroxisome. when pex7 is abnormal, the receptor that usually recognizes and helps transport the pts2 proteins is abnormal. thus, the abnormality of this one receptor has a cascade effect on many other proteins. rhizomelic chondrodysplasia punctata is quite rare. it occurs in fewer than 1 / 100, 000 births. the incidence of peroxisomal biogenesis disorders is approximately 1 / 50, 000 births ; rcdp accounts for fewer than one fifth of these. signs and symptoms " rhizomelic " refers to shortening of the bones near the center of the body ( the bones of the thighs and upper arms more so than the bones of the forearms and lower legs ). " chondro " refers to cartilage and " dysplasia " to abnormal development. " punctata " refers to specific abnormalities seen on radiological studies such as x ray. the ends of the bones near joints appear to be spotted. the spots represent dense, abnormal cartilage. the spots are also called " punctate calcifications. " other abnormalities include frozen joints ( called contractures ), abnormal facial features, cataracts, hearing loss, severe mental retardation, and profound psychomotor retardation. people with rcdp may also have other bone abnormalities, small heads, coarse and sparse hair, and dry, red skin. the proximal shortening of the bones causes short stature, which is apparent before birth. growth after birth is retarded as well. the rhizomelic shortening is severe, and occurs to the same degree on both sides of the body. the stippling ( spotting ) of the bones mainly involves the ends of the bones near the hip, knee, elbow, and shoulder. " severe " mental retardation describes cognitive deficits worse than those of typical down syndrome. some researchers have described degeneration of brain tissue after


the bones mainly involves the ends of the bones near the hip, knee, elbow, and shoulder. " severe " mental retardation describes cognitive deficits worse than those of typical down syndrome. some researchers have described degeneration of brain tissue after birth. researchers are not sure of the reason for this ; it may be due to toxic effects of excess phytanic acid. cataracts are symmetrical and occur in both eyes. the abnormal facial features have been called " koala bear facies. " facial features include a broad forehead and a saddle nose. a subset of people with rcdp do not have some of the typical symptoms, such as shortening of proximal bones and / or severe mental retardation. the diagnosis in these individuals was confirmed to be rcdp. therefore, the spectrum of features in rcdp is variable ; although suspicion of rcdp is raised by the physical and radiographic features, the diagnosis is made by laboratory testing. people with rcdp have very specific biochemical abnormalities, i. e. abnormal levels of particular substances in bodily fluids. these abnormalities are due to the underlying defect in the peroxisome. the specific abnormalities are : 1 ) deficient plasmalogen synthesis with very low plasmalogen levels in red blood cells, 2 ) inability to process ( oxidize ) phytanic acid leading to elevated levels of phytanic acid in the blood, and 3 ) an unprocessed form of peroxisomal thiolase. phytanic acid levels are normal at birth and increase to at least ten times normal by one year of age. some experts recommend that confimatory studies be performed on cells obtained by skin biopsy. the biochemical studies diagnostic of rcdp can be performed prenatally on cells obtained by chorionic villus sampling ( cvs ) or amniocentesis. cvs is usually performed at 10 – 12 weeks of pregnancy and amniocentesis is usually performed after 15 weeks of pregnancy. rcpd may be suspected in a fetus based on ultrasound findings. each feature of rcdp is seen in many other conditions, for example rhizomelic limb shortening is seen in other conditions that cause dwarfism. chondrodysplasia punctata is seen in many inherited conditions but can also be caused by prenatal exposure to the anticoagulant drug, warfarin. doctors who specialize in diagnosing rare genetic conditions use subtle differences between the symptoms of these

strong tradition of non - violence or ahimsa. it believes that god is present in all nature, in all creatures, and in every human being regardless of their faith or lack of it. ’ dr. david frawley we hindus are always proud to hear others praise our culture. we publish them, discuss them in social circles but rarely follow the unparalleled teachings in our scriptures. lord ganesha, holy cow, worship of mountains, worship of nagas ( snakes ), tulsi and the numerous other plants and animals that form part of hindu worship are nothing but messages incorporated by wise hindu saints to teach us that we humans are part of nature and not outside it and above it. the hindu concept of brahman, the supreme soul, suggests that all animate and inanimate and all born and yet to be born are part of brahman. therefore an imbalance in a particular part will affect all other parts. the supreme being then finds out a method to transform that defective part. since brahman is present in all, it is easy to transform. and we humans might term such a transformation as the end or death or total annihilation. for the supreme soul, it is a small repair work carried out by a minute virus. mother nature is not dependent on human beings but human beings are. ancient seers knew it and therefore they worshiped nature. modern humans termed it as animism and replaced it with more refined worships. and the result of such a refined worship... ‘ in our arrogance and ignorance we have destroyed the environment of this planet. we have polluted the oceans, we have made the air unbreathable, we have desecrated nature and decimated wildlife. but the vedantic seers knew that man was not something apart from nature, and, therefore, they constantly exhort us that, while we work for own salvation, we must also work for the welfare of all beings. ’ karan singh only a people ’ s movement can save the earth from destruction. we are armed with wise teachings of our saints. now what we need is its implementation. courtesy : quotes from vedas as found in the articles of dr. s kannan and dr. karan singh


no correlation between oxygen depletion and increased pollutant concentrations. there ' s no way you ' re ever going to get the ods to go off unless you have a way oversized heater in a tiny room, he says. in a 1983 department of energy study, traynor and six other researchers, including mike apte ( author of unvented heaters : drainless sinks? he, sept / oct ' 96, p. 9 ) found that the heaters pose a potential threat to the health of occupants of houses where such appliances are used. meanwhile, a new study from the university of connecticut reports that co can cause permanent brain damage without any single traumatic poisoning. oregon, however, is like most other states where the devices are allowed. legislatures and code officials are reluctant to outlaw the vent - free heaters, for lack of conclusive evidence that they are harmful. as of march 1996, only eight states and eight canadian provinces prohibited the appliances, and codes are steadily becoming more accommodating. the tide turning? today, unvented heaters are being carefully scrutinized in california and new york. after contentious legislative battles in those states, both states ' health officials are seeking reliable sizing guidelines. they hope that by sizing the heaters correctly for the amount of ventilation in a house and for the local climate, they can keep the heaters from hurting anyone. with these developments on the horizon, in march, 1996, the gas research institute ( gri ) released what it hoped would be universally acceptable sizing guidelines. in 1997, the gri guidelines were nominated for incorporation into the ansi national safety standard for unvented gas heaters, z21. 11. 2. these proposed guidelines have turned into a lightning rod for criticism. the gri guideline has been criticized for flawed assumptions and weak science. for example, one indoor air quality researcher with the california air resources board ( carb ) says, the report assumes that a loose house has one air change per hour ( ach ), while a tight house has 0. 35 ach. but 0. 35 ach is probably about average for the good new houses being built in california today, and we often see houses much tighter than this. tom greiner ( author of the case of the co leak : solving the mysteries of carbon monoxide exposure, he nov / dec ' 97, p. 21 ) adds, no attention whatever is paid to a ' worst - case ' or even a less than favorable [ ventilation


of the case of the co leak : solving the mysteries of carbon monoxide exposure, he nov / dec ' 97, p. 21 ) adds, no attention whatever is paid to a ' worst - case ' or even a less than favorable [ ventilation ] scenario. the gas industry traditionally uses worst - case scenarios, and then adds additional safety factors when designing equipment or developing standards. greiner also criticizes the gri assumption that the heaters will be used at most four hours at a time. he cites a homeowner who uses an unvented heater all the time, but calls it a supplemental heater because it heats only part of the house. ken giles of the consumer product safety commission ( cpsc ) agrees. in the burn belt of the south, he says, unvented heaters have traditionally been used as primary heat for many homes without central heaters. the cpsc recommends that indoor heaters not be used while residents are asleep, and produces safety brochures encouraging homeowners to use co alarms. the new york state research and development authority ( nyserda ) produced a peer - reviewed critique of the gri standard. among other things, it criticizes the gri ' s indoor air quality guideline of 0. 5 ppm ( parts per million ) for nitrogen dioxide. no international, federal, or state guidelines that have been adopted are as high as 0. 5 ppm. if an air quality guideline of 0. 25 ppm is used for nitrogen dioxide, air quality will quickly reach unacceptable levels for homes in climates with more than 2, 000 heating degree - days. some such climates include mild santa barbara, california ; st. louis, missouri ; and washington, d. c. the nyserda report also criticized the gri ' s science. the heater sizes recommended, it says, are larger than the heater sizes which were used to calculate indoor air contaminant levels. potential moisture problems are cited by stuart brooks, an architect with energy design associates incorporated of eagle river, alaska. in his eight years at the alaska energy programs office and since then in private practice, he has encountered several unvented heaters. they do create a large condensation problem for houses here in the anchorage area, as well as carbon shadowing on walls and ceilings, he says ( see black stains in houses : soot, dust, or ghosts, p. 15 ). while the vent - free alliance ' s video vent - free iaq research states that


as well as carbon shadowing on walls and ceilings, he says ( see black stains in houses : soot, dust, or ghosts, p. 15 ). while the vent - free alliance ' s video vent - free iaq research states that a humidity level of 60 % is desirable, brooks says that in very cold weather, more than 40 % continuous relative humidity is almost a surefire level of condensation problems. icing on windows, not just condensation, becomes a problem. it is too early to tell whether criticisms of the proposed ansi standard will affect california ' s and new york ' s sizing guidelines. but regardless of what guidelines eventually prevail, one source familiar with california ' s indoor air quality politics points out, it ' s dubious whether sizing standards could be enforced. after all, the heaters are sold as do - it - yourself retrofits at large retailers nationwide. when customers buy and install their units, they may use whatever size they feel fits their needs. crisis or annoyance? for all the problems, there is no epidemic of deaths caused by unvented heaters. even a harsh critic at carb says the current standards, combined with the ods, are likely to prevent fatalities. the vent - free alliance claims that such heaters have caused no fatalities since the ods was first required in the early 1980s. the consumer products safety commission logged over 15 co poisoning events, including 10 fatalities, from unvented gas heaters between december 1994 and january 1997. some of the poisonings were clearly caused by new heaters, but it is unclear whether the fatalities were caused by pre - ods heaters. some manufacturers have experimented with including co detectors with their unvented heaters, but this is not even being considered as part of the revision to the ansi standard. weisner still suffers from reduced stamina and dizziness that were not present before her poisoning. however, because she was not seriously disabled, she has been unable to find an attorney willing to sue fmi. they think the prospective award would be too small to pay the necessary expert witnesses. but with millions of unvented heaters now installed nationwide, she feels it ' s only a matter of time before more people are poisoned. it could have been my grandchildren, she adds. | back to contents page | home energy index | about home energy | home energy can be reached at : email @ example. com - first page - previous page


” ( 242 ). teachers tend to use one instructional approach at the expense of all others, and to be honest, i have seen some hostility among teachers regarding this issue. teachers who prefer direct instruction tend to see teachers who favor constructivism as irresponsible, unknowledgeable, lazy, and at worst, dangerous. it is not unheard of to hear that constructivists are the downfall of education as we know it, and don ’ t you know, education was so much better before these hippie yahoos came along and changed it all. on the other hand, i see constructivists characterize teachers who favor direct instruction as dour, boring, and punitive. in other words, they are the entire reason why kids hate school, and if they just weren ’ t teaching, why think of all we could change! in fact, i think we call all admit there are times when we want to learn things ourselves using a constructivist approach, and i don ’ t know about you, but i have certainly listened to some fascinating lectures. the point of the chapter is not necessarily to advocate one method of instruction over another, but to emphasize that what method you choose needs to be based upon what your desired results are. all of a sudden the necessity for backward design “ clicks. ” how can you figure out whether lecture or a socratic seminar would be best if you don ’ t know what you want the students to understand? in the words of bob the nutrition unit designer, “ what is the best use of our limited time together? ” this should be the mantra of teachers planning instruction. the two pages of formative assessment techniques are well worth some study ( 248 - 249 ). i like the index card summary idea. one of my colleagues uses hand signals with good results. actually, her approach is slightly different from that of the book. she asks students to hold up one finger for one answer, two for another, and three for a third. it ’ s a very quick way to engage all the students and see who understands and who doesn ’ t. i tend to rely too much on discussion, which means if you talk a lot in class, i know what you know. i need to utilize methods of “ hearing ” from silent students more often ( and not necessarily calling on them more often, although that would help ; students are sometimes intimidated and afraid to say “ i don ’ t get it ” ). i want to put a question box in my room, too. i think i


##ity. in sharp contrast to the former soviet union and the united states, recent chinese foreign policy has not been devoted to advancing any higher international ideological interests such as world communism and are generally cynical about the motives of nations, particularly the united states, who claim that they are motivated by higher goals such as spreading freedom, democracy and justice. this cynicism partially comes from chinese thinking in which ideology is secondary to advancing national interest. in this sense, chinese foreign policy makers may be seen to adhere to the realist rather than the liberal school of international relations theory. while this cynicism strikes many as selfish, others have pointed out that the " selfish " nature of chinese foreign policy has made chinese foreign policy extremely flexible and also prevents china from involving itself in the affairs of other nations on ideological grounds. still others point out that in an era of increasing scarcity such selfishness will breed international altercations. in much of the 20th century, chinese foreign policy was based on a sense of victimhood ( of centuries - long western and japanese colonialism ) and a determination to fight back perceived humiliations. at the start of the 21st century, there appears to be a shift in chinese foreign policy and calls from within china to reduce its victim mentality ( 心, shouhaizhe xintai ) and recognize that with a generation of economic growth, that china has begun to fulfil its ambitions of becoming a great power once again and should adopt a great power mentality ( 大 国 心, daguo xintai ) to use its power responsibly and optimistically. these ideas form part of the new security concept which is china ' s vision for the post - cold war era in which nations interact economically and diplomatically for mutual benefit and avoid forming exclusive alliances and / or blocs. modern foreign policy in recent years, china ' s communist leaders have been regular travelers to all parts of the globe, and the prc has sought a higher profile in the un through its permanent seat on the united nations security council and other multilateral organizations. closer to home, the prc has made efforts to reduce tensions in asia ; it has contributed to stability on the korean peninsula, cultivated a more cooperative relationship with members of the association of southeast asian nations ( asean ) ( brunei, myanmar, indonesia, laos, malaysia, philippines, singapore, thailand, vietnam ), and participated in the asean regional forum. in 1997, the asean member nations and the people ' s republic of china, south korea and japan agreed


be checked through alliances with second tier powers such as russia or the european union. this assessment of united states power was reconsidered after the united states intervention in kosovo, and as the 20th century drew to a close, the discussion among thinktanks in china involved how to reorient chinese foreign policy in a unipolar world. this discussion also occurred in the context of china ' s new security concept which argued that the post - cold war era required nations to move away from thinking in terms of alliances and power blocs and toward thinking in terms of economic and diplomatic cooperation. the shift away from a balancing strategy could be seen in china ' s actions after the september 11, 2001 attacks, the united states invasion of iraq, and the accession of hu jintao. although there were some initial fears that american intervention in afghanistan and iraq would lead to an increase in american power and the encirclement and tighter containment of china, the actual consequence was a shift in focus by the united states to the middle east, which resulted in a desire to avoid crises in east asia. after the september 11, 2001 attacks, the blue team in the united states which argued that china was the largest security threat to the united states became much more muted. china was instrumental at brokering talks with north korea over its nuclear program, and in 2003, there was a concerted effort by china to improve relations with the asean nations and form a common east asian market. these foreign policy efforts have been part of a general foreign policy initiative known as china ' s peaceful rise. much of the new diplomatic activity appears to be the result of a change in china ' s self - image. with the accession of the fourth generation of chinese leaders, china appears to be seeing itself less as a victimized developing nation, but rather more as an assertive but responsible regional power. in 2005, there has been talk of the european union lifting its arms embargo, however the united states has objected to this.

climate clinic : libdem conference professor kevin anderson : point of no return without immediate action, catastrophic and irreversible climate change is surely on its way. that is why december ' s summit in copenhagen is so important monday 21 september 2009 the importance of the international climate summit to be held in copenhagen later this year cannot be over - emphasised ; 2009 is literally a make - or - break year in terms of climate - change negotiations. after almost two decades of increasingly heated debate on how to tackle climate change, and notwithstanding the current recession, emissions of global greenhouse gases – from energy use, agriculture, deforestation and industrial processes – are rising at a faster rate now than they have done throughout our history. as we enter the second decade of this new millennium, the international community is faced with a very clear and stark choice : to cut emissions urgently and radically, or to lock the next and future generations into " dangerous climate change ". for far too long now, scientists, politicians, the media and the public, while broadly accepting the science and implications of climate change, have stubbornly refused to acknowledge the scale of rising emissions. so while the rhetoric of low - carbon action has been notched up year after year, the reality is that collectively we have been on a high - carbon binge. unfortunately, most of the emissions we have put into the atmosphere over the 17 years since the earth summit in rio and the 12 years since the start of the kyoto process, will remain there for another century – added to, year on year, by our increasingly carbon - profligate lifestyles. it is this cumulative nature of emissions, whereby the concentration of greenhouses gases builds up in the atmosphere, combined with our abject failure even to curtail emissions ' growth rate, that has brought us to this political tipping point. either our politicians step up to the plate in copenhagen and agree to implement an immediate reversal in emissions trends, or we consciously accept a continued and rapid build - up of emissions in the atmosphere with all the implications that entails. we no longer have the luxury of lengthy negotiations such as those associated with the kyoto protocol. as for the scale of reductions necessary, again here we have all been party to downplaying the severity of the issue and are now faced with the consequences of this delusion. in this regard i and my colleagues in the scientific community are particularly responsible. for too long we have, with notable exceptions, been reluctant to spell out clearly the true implications of our analysis, instead couching our conclusions as challenging


of this delusion. in this regard i and my colleagues in the scientific community are particularly responsible. for too long we have, with notable exceptions, been reluctant to spell out clearly the true implications of our analysis, instead couching our conclusions as challenging but politically palatable. however the scientific climate congress held in copenhagen earlier this year, as a prelude to the political event in december, witnessed a sea - change in attitude among many in the scientific community. the message to policy - makers, businesses and the public is unambiguous. radical reductions are needed now to give us even a small chance of avoiding the 2°c threshold between " acceptable " and " dangerous " climate change. putting this into everyday language, the wealthy, oecd, nations need to reduce their total emissions by at least 40 per cent by 2020, including emissions from aviation and shipping, and without buying emission reductions from poorer nations. complete decarbonisation of the oecd ' s energy system needs to be in place by 2030. however these figures may be massaged, such reduction rates are incompatible with the current framing of economic growth. new low - carbon technologies are available, but for them to dominate our energy system will take at least two decades, time we simply don ' t have, as in the interim our emissions continue to build up in the atmosphere. only once our energy system is carbon - free and our meat - eating substantially curtailed can we again consider seriously having a growing economy – provided it can be reconciled with the other demands of sustainability. however, even such draconian reductions by the oecd nations leave only limited opportunities for the poor and less - wealthy nations to continue to increase their emissions. consequently, while emissions in these nations will rise as their welfare improves, this rise needs to be kept to a minimum through comprehensive low - carbon technologies and policies. ultimately, all nations across the globe will need to establish carbon - free societies over the coming few decades, completely counter to the rapid emission growth we have experienced since 2000. while much of this rise has been driven by the newly industrialising nations of china and india, the problem to which they are now contributing is one caused by our emissions and to which we still are a major contributor. according to the department of food and rural affairs ( defra ), absolute uk emissions have risen by 18 per cent since 1990, and show no clear of signs of bucking this trend in the near term. the recent and much - heralded us waxman - markey bill requires no reductions

301 geniuses, and then she and a team of independent raters – including terman and florence goodenough – used these data to derive the iq estimates. in addition, she showed that estimated iq correlated with achieved eminence. furthermore, for a subset of 100 geniuses she computed ratings on 67 character traits. on the basis of these scores she was able to conclude that motivation, determination, and persistence were also critical to high achievement. the resulting doctoral thesis was sufficiently impressive that terman had it published as volume 2 in his genetic studies of genius. not only was this the only volume that did not involve the longitudinal study of his “ termites, ” but it is also the only volume that did not include terman as an author or co - author. at 842 printed pages, it can easily be considered the most ambitious historiometric investigation ever published. moreover, many of her key findings have been replicated in subsequent research. unfortunately, cox was soon diverted from this work by ( a ) her collaboration with terman on a masculinity - femininity measure and ( b ) her marriage to walter miles ( a recent widower with two teenagers ). she also started publishing under her married name miles rather than cox. however, a decade later she returned to the historic geniuses that were the subject of her thesis. miles and wolfe ( 1936 ) specifically scored the geniuses on early mental and physical health. their aim was to show that intellectual giftedness was also positively associated with both mental and physical well - being. cox. c.

protecting yourself from cybercrime ( bpt ) - gone are the days when hackers were the weekend enthusiasts you tolerated on the golf course, when viruses were the things that gave you the flu or a cold, and phish was a popular jam band who served as the inspiration for your favorite flavor of ben and jerry ' s. with the rise of the internet and electronic devices has come the rise of cyber - related crime. cybercrime, as it is called, is defined as a criminal activity using computers or other electronic devices to victimize people, organizations or businesses. " despite a global recession, improved security and international crackdown efforts, cybercrime has thrived over the last decade, growing by double digits year after year, " says clint kirkwood, a professor of criminal justice at argosy university, orange county and 28 - year veteran and retired commanding officer of the vice section of the narcotics division of the detroit police department. while estimates of the cost of cyber crime to businesses and the private sector vary, a 2011 publication released by javelin strategy and research, the annual cost of identity theft alone was $ 37 billion. " today, some of the most successful criminals do not have to leave the comfort of their own homes to pull off crimes bigger than ever. all they need is an internet connection, a little tech savvy and a lot of bad will, " says kirkwood. the internet crime complaint center received more than 300, 000 complaints in 2011, which included such crimes as fbi - related scams, identity theft, advance fee fraud and a host of romance, work - from - home, auto auction, loan intimidation and other scams. " since the take - off of social networking and the paperless way of conducting business, cyber - based criminal activity has skyrocketed in many corners of the world, " says gary gonzales, a professor in the criminal justice program at argosy university, san diego and police detective in his 16th year of service with the san diego police department. " criminals are masking themselves as potential customers, clients or even professionals to lure innocent people into a web of deception and greed. from copyright infringement and cyber bullying to child pornography and spamming, the impact is enormous. " knowing the threats you face online and the tools available to help you keep a watchful eye is critical in protecting yourself in the digital world. there are simple precautions that computer, mobile phone and other digital users can take to ensure their safety. do not open emails / attachments from unknown or suspicious

in kansas and throughout the northern midcontinent area, excepting parts of oklahoma and arkansas, definition of the lower limit of pennsylvanian rocks is one of the most evident in the rock succession ( fig. 3 ). not only are the types of sedimentary rocks on opposite sides of the boundary very dissimilar generally, but there is evidence of pre - pennsylvanian erosion of the underlying strata and varyingly prolonged break in sedimentation. the basal pennsylvanian rocks rest on different parts of the mississippian succession, from high in the system down to the bottom - most beds, and at many places, both at the outcrop in missouri and in the subsurface of kansas and nebraska, the pennsylvanian overlaps on to pre - mississippian rocks. the oldest pennsylvanian deposits in most of this territory are clearly much younger than rocks classed as belonging to the system elsewhere. accordingly, there is no problem in marking the base of pennsylvanian strata in the kansas region. figure 3. diagrammatic east - west section of rocks in kansas showing prominent unconformity at base of the pennsylvanian system. the section, drawn on the base of the kansas city group as a datum, shows essential conformity of succession from pennsylvanian into permian parts of the section. ( after moore, am. assoc. petroleum geologists ; data from section by betty kellett, kansas geol. soc., 1932. ) a larger version of this figure is available. definition of the boundary between rocks classed as pennsylvanian and permian in the kansas region has led to much debate and disagreement. ulrich ( 1911, p. 376, pl. 26 ) proposed to avoid the difficulty by not recognizing permian at all and by defining as pennsylvanian all of the rocks between mississippian and triassic. this procedure might be defended on the basis of the stratigraphic succession in the midcontinent area, but it is evidently unsuited to world - wide application. because beds having pennsylvanian and permian fossils lie parallel and are seemingly conformable in kansas and adjoining states, attempts to define the base of the permian in this area have been based chiefly on study of fossils. consideration has been given also to lithologic features and the desirability of selecting a convenient cartographic datum. judgment has been generally expressed that any adopted boundary is measurably arbitrary. the general tendency during the 90 years since permian deposits were first recognized in kansas and in north america as a whole has been to lower

challenges to india ’ s patent regime : pharma industry the works of the founder of the states, law givers tyrant destroyers and heroes cover but narrow spaces, and endure but for a little time, while the work of the inventor though of less pomp is felt everywhere and last forever. ( francis bacon ) a patent is an exclusive right granted to a person who invented a new article or an improvement of an existing article or a new process of making an article. it consists of an exclusive right to manufacture the new article invented or manufacture an article according to the invented process for a limited period. object of patent law : the object of granting a patent is to encourage and develop a new technology and industry. an inventor may disclose the new invention only if he is rewarded, otherwise he may work it secretly. thus the theory upon which the patent system is based upon is that the opportunity of acquiring exclusive rights in an invention stimulates technical progress in four ways : • that it encourages research and invention • that it induces an inventor to disclose his discoveries instead of keeping them as trade secret ; • that it offers the reward for the expenses of developing invention to the stage at which they are commercially practicable ; and • that it provides an inducement to invest capital in new lines of production which might not appear profitable if many competing producers embark on them simultaneously ; value of patent system : some controversy exists as to precise extent of the contributions made by the patent system to the economic development of a country. but the adoption of some kind of the patent production for inventions in all most all countries, and the ever increasing number of applications for patents received by the patent offices in all industrially advanced countries is an indication of the universal recognition of the value of the patent system. most of the inventions and discoveries made in technology in all fields are published in the patents specifications field in the patent offices of different countries. a world wide exchange of technical information has been made possible only by the publications of such patent specifications. in a sense patents have assumed an international character. the increasing number of applications for patents from foreigners received in almost all countries in recognition of fact. attempts are being made from time to time by international associations for the protection of individual property and to introduce more and more uniformity and harmonization among national patents systems. the international convention for the protection of industrial property ( paris convention ) and gatt and trips agreement are examples of attempts at harmonization of the law of patents & other forms intellectual property. main provisions associated with trips agreement the trips consistent indian patent law addressed


the international convention for the protection of industrial property ( paris convention ) and gatt and trips agreement are examples of attempts at harmonization of the law of patents & other forms intellectual property. main provisions associated with trips agreement the trips consistent indian patent law addressed three important issues relating to patent of products : i ) adoption of definition of “ pharmaceutical substance ” ; ii ) exclusion of “ mere discovery of a new form of known substance ” and “ new use for a known substance ” ; and ( iii ) protecting the interests of those who are already producing the products which may be granted patent protection in the new regime. the patent regime adopted in trips by the developed countries is somehow of the capitalists nature and it prioritizes the profit motive over the social responsibilities. in continuation to these discrepancies, trips also rule out any discrimination between the technological sectors and advocates the same protection for all the technological inventions fulfilling the criteria. even after the acceptance of the trips agreement, the following five major areas still controversial for both the parties to the trips : 1 ) iprs and access to medicines, 2 ) iprs, community property rights and indigenous knowledge, 3 ) iprs and biodiversity, 4 ) iprs, biotechnology and agriculture, 5 ) ipr policy and trade. there is no doubt that “ product patent regime ” have spurred the r & d for diseases - notably, those with the lucrative potential market in the industrialized world. however, trips has failed and will continue to fail to stimulate sufficient r & d for diseases that primarily affect poor countries. trips had forced all the developing countries to switch over to product patent regime from process patent regime and hence, restrict the access of the cost effective essential medicines to their people. challenges to patent regime in india india enjoys several strengths amongst others developing and least developing countries, particularly, in case of the production of the food grains and drugs, and proudly hosts world cheapest pharma industries. even with these impressive facts, one billion indians, spend the same amount on medical drugs per year as seven million men and women in switzerland. the amount spent on drugs here in india roughly corresponds to the profit made by a single pharma mnc “ novartis ” in a typical year. these figures are enough to reflect the dying conditions of the public health services in india. it is now almost a well established fact that trips provisions have already started affecting a person ’ s human right to access health services ( india and the wto ) hiv / aids alone have caused death of about 3 million people in 2002, including


the letter and spirit in which india transitioned into the new patent regime has been put to litmus test by novartis which sued india with the institution of a writ petition before the high court of judicature at madras. several countries praised india ’ s contribution to life saving drugs and requested novartis not to challenge. however, novartis filed its case with indian court at chennai and sought patentability of its product gleevac filed under emr provisions on the grounds alleging : ( i ) illegality in procedure adopted and also the text of 3 ( d ) of the act which was in violation of article 27 ( 1 ) and 27 ( 2 ) of trips agreement ; ( ii ) arbitrariness by the controller general of patents & designs, chennai and ignoring rationality underlying articles 253 and 51 ( c ) of the indian constitution whereby national laws are required to be harmonized with international treaties ; ( iii ) provision relating to discovery of “ new form ” contained in 3 ( d ) is illogical and against the concept of patents which encourages innovation and intervention by rewarding the person associated with such acts beneficial for society ; ( iv ) deliberate incorporation after approval of its product gleevac under the earlier prevailing emr provisions resulted in disturbing the level playing field laid under the act in compliance with conditionality under trips agreement. the technical expert group on patent law issues with mr. mashelkar as it ’ s chairman ( mashelkar committee ) submitted its report to the government of india on its terms of reference which favoured incremental modifications / innovations for qualifying for the grant of patent as new chemical entities ( nce ). several ngos opposed the case filed by novartis and urged the doctors and medical professionals to boycott its products in india. the indian court rejected the plea of novartis on patent of gleevac for violation of trips agreement. this patent case is considered to be a threat to developing nations and the treatment of aids patients will be seriously impaired if novartis ultimately succeeds in obtaining favourable award on its patent matter from the higher courts in india revival of yoga and impact of baba ramdev baba ramdev revived pranayama which acts as the best medicine involving rhythmic control of breath through bodily exercises and awakens divine powers essential for curing disease and enabling creation of " disease free society - medicines free world ". yoga pranayama & the ayurvedic & herbal medicines used at baba ramdev ’ s yoga camps have scientifically proved to provide cure for most of the diseases including : ( i ) control &


written by jonny williamson lubricants are used across many industries throughout the world, predominantly to cool tools and parts from overheating and breaking by reducing friction and carrying away debris. industrial processes such as drilling, turning, grinding, cutting and milling all benefit from lubricants, often made from 90 percent mineral oils. there are a number of drawbacks to using mineral oils ; it isn ’ t an ideal way to dissipate heat caused by friction, it is flammable and it does carry some health concerns, not to mention the fossil oil comes from a finite resource. the safe use, handling and eventual disposal of mineral oil lubricants can amount to a constant drain on a manufacturers finances, so a global focus has been on finding an alternative. + more from manufacturing digital - web elements manufacturers need in the digital age - mas reports shows uk manufacturing is on the rise - manufacturers need more government support says survey researchers from the fraunhofer institute for process engineering and packaging ivv, in the german town of freising, have carried out two tests where lubricating oils were replaced with water. dr. michael menner, a fraunhofer researcher, said : " at ivv here in freising, we have been looking at the issue of cooling lubricants for some considerable time. in two projects, supported by the federal ministry of education and research, we have successfully replaced oil with water. ” to enable the water to act as a sufficient lubricant, additives were added to better simulate the performance of oil. another researcher, andreas malberg, who also worked on both studies, commented : “ the additive is a biopolymer, a product you can buy wherever you want. ” malberg was not able to state the name of the exact biopolymer employed by the researchers, but what is known is that it acts as a thickening agent. the standard viscosity of water is 1mpa, but the addition of the agent raises it to 40mpa, similar to that of oil. the further addition of a water - soluble additive enabled the enhanced water to have the extra benefit of providing anti - corrosive properties. aside from the water - based lubricant having a much lower environmental impact, components and machines which use the lubricant are easier to clean, health and safety concerns are eliminated, and the cost of companies having to convert is relatively inexpensive, the alternative lubricant has already won the german raw


yes - of course it does. without " random " in front choice is an attribute with no object. i didn ' t actually do it, but thats what would happen - " choice is not defined blahblah " is that the same as saying its not a " global namespace "? i ' d have to consult a reference book to be 100 % sure. i ' m not certain how a pure object oriented language treats namespaces compared to a procedural language ( ie, c + + is both procedural and oop - i need to do a review for example, in c + + you explicitly state your namespaces - in 99 % of cases students do this by adding a line ' using namespace std ; ' ( std = standard ) near the top of their file, which is frowned upon with most real projects. by doing this they don ' t have to put the namespace std in front of functions defined in std. cout < < " hello " < < endl ; / / prints hello std : : cout < < " hello " < < std : : endl ; / / prints hello now say you have a special cout function that prints ascii numbers instead of the letters to the console. you can define a namespace in your file called manta and do this.... manta : : cout < < " hello " < < std : : endl ; / / prints 90 88 96 96 99 ( just guessing the ascii values ) in practice, namespaces are used in procedural languages to avoid name clashes. when a project gets large enough, you start running out of good descriptive variable names, so it is better to create seperate namespaces and reuse these descriptive names instead of resorting to complicated naming gyrations. " it looks to me like random might be a static class with static methods, hence, no need to instantiate anything. " yes - a very good way to say it. how come the texts don ' t say that? got me - maybe i should write a book. this is just what i think is happening... i ' d have to consult python. org to be sure. do java and c + + have modules? please describe or give a definition to me for that. no. java has the following.... packages - groups of related classes form a package. example : javax. swing is the package for the swing classes example : java.


modules? please describe or give a definition to me for that. no. java has the following.... packages - groups of related classes form a package. example : javax. swing is the package for the swing classes example : java. lang contains the core classes of the java language classes - you know what these are.... math is a class containing fields and methods related to math jbutton is a class for instantiating a button in swing and you can create your own packages.... there are a few rules for doing this. in c + +, which supports both procedural and oop, the main library is called the stl - standard template library, which uses the namespace std like i showed you above. instead of using a package, c + + has a keyword called friend - imo, friends are the most unfriendly thing i ' ve seen in any language and i much prefer java ' s use of packages. my language class didn ' t cover python - c + +, java, ada, lisp, fortran, prolog, cobol and some others - here is what one of the tutorials says... you can use a module to organize a number of python definitions in a single file. < snip > a package is a way to organize a number of modules together as a unit. python packages can also contain other packages. so python has both modules and packages where it looks like a module is a related to group of classes and functions, and a package is a related group of modules and other packages. here is a link that i think will explain it in detail.... i plan on reading it later tonight.

" if grief turns into depression, the feelings of despair and emptiness become constant. loss of motivation, hopelessness, fatigue, withdrawal, and difficulty concentrating are also signs of depression. people with complicated grief get stuck in the feelings and don ' t move on, deny the death, become preoccupied with the person who died, or avoid things related to the person. completing the grief process is important because it can help you to recognize and adapt to the reality of the loss and to live a healthy life without the person who died. there is no right way to grieve or a set time to complete it. all losses are unique and reflect the quality of the relationship with the deceased, the characteristics of the griever, prior experiences with loss, and the circumstances of the loss. a loss that occurs as a result of a prolonged illness will be different from the grief resulting from a sudden death. grief from a sudden death may be more intense since there has been no opportunity to prepare for


loss, and the circumstances of the loss. a loss that occurs as a result of a prolonged illness will be different from the grief resulting from a sudden death. grief from a sudden death may be more intense since there has been no opportunity to prepare for the loss. grief resulting from the death of a child is different than that from death of a parent. some people try to avoid the painful feelings of grief by keeping very busy and pretending that they are all right. failure to address the feelings that come with the normal grieving process can prolong the grief process and possibly lead to depression later. the grief process involves recalling a collection of memories and stories about the person that died. it may involve talking and writing about the good and bad memories about your time with the person. it is common to have regrets about things that you believe you should have said or done and you will need to let go of them. grieving means allowing yourself to acknowledge, experience, and release the many feelings that occur when you lose someone. grief recovery can be defined as acceptance of the death of a loved one and return to your previous healthy level of functioning. a sign that you have completed the grief process may be the ability to increasingly choose happiness and smile when you remember the person. just as an injured body gradually weaves itself back in a whole, death of a loved one tears at the spirit but grieving allows it to heal. david gannon, ph. d., psychological and family consultants, canton, ohio.

from our 2012 archives young puzzle - solvers may be tomorrow ' s engineers latest healthy kids news friday, march 2 ( healthday news ) - - playing with puzzles when they ' re 2 to 4 years old can help children develop better spatial skills, a new study indicates. spatial skills refers to the ability to think about objects in three dimensions. university of chicago researchers examined the interaction between 53 pairs of children and parents, and found that children who played with puzzles between 26 and 46 months of age had better spatial skills when they were 54 months old. the researchers also found that : higher - income parents tended to encourage their children to play with puzzles more often ; boys played with more complicated puzzles than girls ; and parents of boys used more spatial language during children ' s puzzle play and were more engaged in puzzle play than the girls ' parents. " the children who played with puzzles performed better than those who did not, on tasks that assessed their ability to rotate and translate shapes, " psychologist susan levine, an expert on mathematics development in young children, said in a university news release. she noted that this type of ability is an important predictor of children choosing science, technology, engineering and math courses, degrees and careers later in life. the study was published online in the journal developmental science. " further study is needed to determine if the puzzle play and the language children hear about spatial concepts is causally related to the development of spatial skills - - and to examine why there is a sex difference in the difficulty of the puzzles played with and in the parents ' interactions with boys and girls, " levine said. - - robert preidt copyright © 2012 healthday. all rights reserved. source : university of chicago, news release, february 2012 get the latest health and medical information delivered direct to your inbox free!
