    'title: Urban narrative: Computational linguistic interpretation of large format public participation for urban infrastructure\n\nauthors: Dyer, Mark\n\nabstract: Urban Narrative works at the interface between public participation and participatory design to support collaboration processes for urban planning and design. It applies computational linguistics to interpret large format public consultation by identifying shared interests and desired qualities for urban infrastructure services and utilities. As a proof of concept, data was used from the Christchurch public engagement initiative called ‘Share an Idea,’ where public thoughts, ideas, and opinions were expressed about the future redevelopment of Christchurch after the 2011 earthquakes. The data set was analysed to identify shared interests and desired connections between institutional, communal, or personal infrastructures with the physical urban infrastructures in terms of buildings, public places, and utilities. The data has been visualised using chord charts from the D3 JavaScript open source library to illustrate the existence of connections between soft and hard urban infrastructures along with individual contributions or stories. Lastly, the analysis was used to create an infographic design brief that compares and contrasts qualitative information from public consultation with quantitative municipal statistical data on well-being.\n\ntext: Urban narrative: Computational linguistic interpretation of large format public participation for urban infrastructure Urban Narrative works at the interface between public participation and participatory design to support collaboration processes for urban planning and design.

  maori_origin	title: KAUMĀTUATANGA Supporting School Leaders To Develop Cultural Values While Resisting The Dominance of Colonialism authors: Nuri, Ngahuia subjects: Kaumātua abstract: In an education system that is asserting to the importance of Māori (indigenous people of Aotearoa) language, culture, identity and the history of Aotearoa (New Zealand) into the curriculum, there is direction from the Ministry of Education (MOE) for schools to reach out to iwi. What this looks like and how this can be achieved is not an easy task. This thesis follows the journey of three kaumātua (respected, knowledgeable elders, both female and male) working alongside the Senior Leadership Team (SLT) of a decile 10 kura auraki (mainstream primary school) where ākonga Māori (Māori students) were in the minority. The research examines what role kaumātua might have in guiding other schools to help tamariki Māori (Māori children) enjoy and achieve education success as Māori. It highlights the coming together of lea...	title: Studies of New Zealand Marine Organisms authors: Till, Marisa subjects: Natural products abstract: The chemical study of three New Zealand marine organisms is described, along with a survey of the chemistry and biological activity of eighty-five marine organisms collected from New Zealand waters. The study of the New Zealand marine bryozoan Pterocella vesiculosa has resulted in the isolation of three new compounds; pterocellin H, pterocellin I and 1-methyl-5-bromo-8-methoxy-β-carboline. These compounds were characterised using high resolution mass spectrometry, one- and two-dimensional nuclear magnetic resonance spectroscopy and X-ray crystallography. The biological activity of these compounds was investigated and a discussion of the results including a comparison with the activity of closely related compounds is also presented. The crude extracts of eighty-five marine organisms were surveyed to establish their biological activity and chemical constituents. The results of thi...
  maori_origin	title: Taku Ara, Taku Mahara: Pākehā Family Experiences of Kaupapa Māori and Bilingual Education authors: Barnes, Alexander Louis subjects: Kaupapa Maori abstract: Kaupapa Māori (indigenous Māori-centred philosophies) initiatives have transformed various social, cultural and public projects in the domains of governance and constitutional issues, health, education, the environment, community development and research in Aotearoa – New Zealand. As a Pākehā graduate of te kōhanga reo and kura kaupapa Māori (Māori language immersion pre-school and primary school), this research is concerned with exploring the impact of kaupapa Māori and bilingual educational initiatives on my life and the lives of two other Pākehā families who share similar educational backgrounds. This foundational study utilises qualitative narrative inquiry methods as a means of understanding and analysing the implications for Pākehā as a result of their participation in kaupapa Māori and bilingual education. An inter...	title: What is creative to whom and why? Perceptions in advertising agencies authors: Koslow, Scott abstract: The authors apply recent advances in creativity theory to discover perceptual differences in the factors of strategy, originality, and artistry among creatives and noncreatives. It was found that current advertising position influences subjective perceptions of what constitutes creative advertising. Creatives tend to perceive advertisements as more appropriate if they are artistic, but account executives tend to perceive advertisements as more appropriate if they are strategic. The study also indicates that creatives have a distinctive preference for a strong originality component to strategy. To be original within the confines of a tight strategy is perceived as the most creative by advertising creatives. Account executives are so focused on strategy, they will often accept artistic advertisements as a substitute for truly original work. The authors consider future research ...
  maori_origin	title: Te whakahuatanga i te reo Māori: Kua ahatia e tātou i roto i ngā tau 100 kua hipa nei? (The pronunciation of Māori: What have we done to it in the last 100 Years?) authors: Harlow, Ray subjects: Te reo Māori abstract: In the words of the proverb: 'The land remains, but humankind vanishes.' One should perhaps extend this to read: 'The land remains, humankind vanishes, and language changes.' For languages are old, handed down from one generation to another, but no matter what, they change. Present-day English is not Shakespeare's or Chaucer's language. The pronunciation has changed, new words have entered the language, some words have been lost, the grammar is now different. Māori is like that as well. Over the last two centuries, many aspects of the language have become different. Many words have been borrowed from English, and become part of the language. Many new words have been created in recent years to accommodate the new topics now being spoken about in Māori. Many words...	title: A contrast-sensitive, redundancy reduction mechanism acting on MT neurons can explain global motion direction biases without the need for Bayesian priors authors: Perrone, John A. subjects: Bayesian observer model abstract: Introduction: The perceived global direction of moving objects can be influenced by the contrast of the object (Weiss, Simoncelli & Adelson, Nature Neuroscience, 2002). There is currently no detailed, neural-based explanation for how this could occur. Weiss et al., proposed an ideal Bayesian observer model that included a physiologically unspecified ‘low speed’ prior. We have recently developed a new velocity code for extracting image velocity from small groups of MT neurons (Perrone & Krauzlis, VSS 2011). The code includes a stage of local spatial inhibition between MT neurons designed to reduce the amount of redundant signals passed onto the global motion integration stage (MST). The inhibition is made dependent upon the contrast of the stimulus by explo...
