title: The effect of flotation cell shape on deinking behaviour

authors: Jones, Lewis

subjects: engineering

abstract: Studies were undertaken to investigate the deinking behaviour of different shaped deinking cells of the same volume. For comparative purposes, most oprational variables were kept constant, and the same injector was used throughout the study. The position of the injector, however, was varied in some cases to go along with the particular cell shape being studied. 

Three types of cell shapes were studied, (1) cylindrical with tangential air injection, (2) rectanular with vertical injection, and (3) rectangular with horizontal injection. Eucalyptus/toner slurries and news/mag wastepaper slurries were deinked. Flow patterns in the cells and the corresponding deinking efficiencies were measured. 

It was found that strong and excessive re-circulatory flows within the cells could under certain conditions be a major factor in reducing brightness lift. Vertical injection into a rectangular cell gave stable flow patterns, non-wavy froth removal and sustained brightness lift for a wide range of feed and airflow rates. Horizontal injection into a similar rectangular shaped cell exhibited quite different characteristics. High brightness lift was possible for certain conditions and not for others. Wavy froth and excessive recirculation flow patterns varied with feed and airflow. The cylindrical cell with tangential injection gave stable circulatory flow and stable froth removal at low flow rates but was unable to deink at high flows.

title: Searching for happiness in ‘other worlds’: Utopias and dystopias in Japanese isekai

authors: Wang, Xueqian (Amy)

subjects: Isekai

abstract: This thesis focuses on the popular, but under-researched genre, of isekai. Although the wider medium umbrella under which isekai falls — anime, manga and light novels — have received increasing critical attention, the isekai is a genre that has only begun to be academically explored over the last three to four years, particularly from 2020 onwards. Literally translating to ‘another world,’ it is a branch of the familiar portal-quest fantasy category that has, particularly in recent years, formed its own, distinctive formulas and tropes. This thesis makes an important contribution to unpacking and understanding this surprisingly complex and nuanced genre that offers readers and viewers both entertainment, and a way of thinking about relevant issues to do with personal happiness and self-fulfilment. In this thesis, I will offer an analysis of three isekai narratives through the primary lens of utopian and dystopian discourse, highlighting the way in which the isekai explores both human desires and fears. Hybridity is a key finding of my analysis, with the genre not only juxtaposing and combining utopia and dystopia, but also, old and new worlds, portal-quest and immersive fantasy elements, and Western and Japanese literary and cultural perspectives. This hybridity points to the entangled, interconnected nature of utopia and dystopia itself.
The three texts I have chosen all follow the contemporary isekai trend of featuring adult protagonists (as opposed to teenagers), the “Japanese Salaryman/woman”, worn out by work and modern society. The three series that I analyse are That Time I Got Reincarnated as a Slime (2014) by Fuse, By the Grace of the Gods (2017) by Roy, and I’ve Been Killing Slimes For 300 Years and Maxed Out My Level (2017) by Kisetsu Morita. Each of these new worlds is structured in a way that encourages the protagonist to embrace personal desires that were suppressed on Earth, and provides a sense of healing. With the skills and knowledge inherited from Earth, combined alongside the new abilities the protagonists gain as they are reincarnated or summoned into the new world, the central characters are granted the opportunity to create a new, utopian life for themselves. By extension, they exert an influence on the land and people around them to ultimately forge a more utopian world. The way that the protagonists navigate and explore their relationship between both old and new worlds, as well as their old and new selves, further reveals a more complex relationship between utopia and dystopia. The recurring cultural aspects present in these texts, most notably cuisine and business practices, emphasises the desire for cultural fusion, as well as offering insightful social critique. While the new world also contains dystopian elements, I propose that the isekai can be viewed as a new reimagining of a Japanese utopia.

title: Teachers' perceptions of the effectiveness of the Whānau Rūmaki teacher education programme, 1990-1992

authors: Kana, Fred

subjects: Maori Language

abstract: In 1990 the School of Education, the University of Waikato, initiated a special option within its regular pre-service teacher training programmes, an option designed to prepare teachers to deliver the New Zealand curriculum in bilingual and total immersion schools through the medium of te reo Māori. This alternative programmed, designated Whānau Rūmaki, was experimental and evolutionary. Inevitably particular elements of it had to be varied with each year's operation as its architects attempted 'to get the mix right'. It is difficult, however, when engaged in the day to day running of a programme, to stand back and review with any degree of objectivity its strengths and weaknesses. This study, therefore, in retrospect attempts to do three things: one, to follow the initial Whānau Rūmaki student cohort through its three or four year training cycle noting especially the difficulties confronting individual students some of whom dropped out of the programme; two, to gather information from as many as possible of the graduates who graduated about how well they felt they had been prepared for the rigours of classroom teaching; three, to be able, after analysing the data gathered, to recommend ways of improving the on-going Whānau Rūmaki programme.
