title: Chitosan: A review of sources and preparation methods

authors: Kou, Shijie

subjects: Science & Technology

abstract: This review aims to explore different sources of chitin and methods of chitosan production with industrial consideration. This article first discussed different sources of chitin for industrial scale production, with considerations given to both their environmental impacts and commercialization potential. Secondly, this article reviews the two categories of chitosan preparation – chemical methods and biological methods - based on existing publications which used lobster by-products as a feedstock source. The mechanisms of the chemical methods are firstly summarized, and then the different chemical agents and reaction parameters used are discussed. Next, both enzymatic and fermentation-based approaches are reviewed under biological methods and compared with chemical methodologies, with lactic fermentation methods as the major focus. This article concludes that lobster cephalothorax could be an ideal source for chitosan preparation on an industrial scale; and chemical methods involve simpler processing overall, while produce chitosan with stronger bioactivities because of lower molecular weight (MW) and higher degree of deacetylation (DD) achieved by the products. Moreover, due to biological methods inevitably necessitating further chemical processing, an approach involving some unconventional chemical methods has been regarded as a more suitable strategy for industrial scale chitosan production.

title: Dreamers of the Dark: Kerry Bolton and the Order of the Left Hand Path, a Case-study of a Satanic/Neo-Nazi Synthesis

authors: van Leeuwen, Wilhelmus Roelof

subjects: Kerry Bolton

abstract: In 1990 a small self-published journal/magazine called The Watcher was distributed among New Zealand's occult underground.  The Watcher described itself as 'the New Zealand Voice of the Left Hand Path', and was published as the journal of the Order of the Left Hand Path.  The Watcher and the Order directed its attentions towards those occultists who identified themselves as Satanists and, as such, the journal articulated a distinctly Satanic philosophy and perspective.  However, as the journal evolved and developed, renaming itself as The Heretic and The Nexus in later years, there arose alongside Satanic philosophy an increasing emphases on what could be called esoteric Nazism or esoteric Nationalism.  Given that the editor of The Watcher was Kerry Bolton, a man who has been immersed in New Zealand's Nationalist/neo-Nazi movement since the early 1970s, such an increasingly political orientation was perhaps unsurprising.

This thesis examines the way in which the Order bought Satanic and neo-Nazi ideologies together and the resulting synthesis.  It also looks at the transition from being a Satanic order led by a neo-Nazi to an openly neo-Nazi Order that uses Satanic philosophy to justify and popularise its conception of National Socialism.

title: The “standard story” of anti-Māori talk in Pae Ora (Healthy Futures) Bill submissions

authors: Black, Rose

abstract: AIM: To review some common patterns of race talk in a sample of submissions made to the Pae Ora (Healthy Futures) Bill. This bill proposed a structural reform of the health system in Aotearoa New Zealand to address long-standing health inequities experienced by Māori, the Indigenous peoples, and other priority populations. METHOD: In a sample of 3,000 individual submissions made in late 2021, we found 2,536 explicit references to race. Utilising the “stan-dard story” frame of Pākehā/non-Maori race talk, five longer submissions that inferred that the Pae Ora bill was “racist” were analysed in detail. RESULTS: Many “standard story” race discourses were identified in the Pae Ora submissions. Three derived discourses included in this paper are: Pākehā as norm (monoculturalism or not seeing Pākehā as a culture), equality and the “Treaty” (equality for all to access healthcare), and one people (we are all New Zealanders). Sources such as the Waitangi Tribunal Wai 2575 Hauora report were drawn on to provide alternative discourses. CONCLUSION: Identifying Pākehā standard story discourses enables learning about language patterns systems draw on, and the development of tools and procedures to improve equity for Māori and eliminate institutional racism.
