title: Celebrating the joy of teaching

authors: Tulloch, Bridget

subjects: teaching

abstract: I am excited to be writing this article on celebrating teaching, because all too often it feels like research is celebrated more than teaching at the university. This is perhaps because research has obvious measurable rewards such as being granted research funding or producing a paper. Teaching produces its own rewards but these are far less obvious and can be different for every teacher. When I wrote my teaching portfolio I opened with the quote of “we teach to change the world” (Brookfield, 1995), and while this seems cliched, it is so very true. The rewards in teaching for me are the interactions with students and seeing that moment when there is a spark as ideas click and make sense. It is the connections with students I want to focus on in this piece because for me that is why I teach.

title: Recycling of waste glass as aggregate in cement-based materials

authors: Harrison, Edward

abstract: Glass is a common material made from natural resources such as sand. Although much of the waste glass is recycled to make new glass products, a large proportion is still being sent to landfill. Glass is a useful resource that is non-biodegradable, occupying valuable landfill space. To combat the waste glass that is heading to landfill, alternative recycling forms need to be investigated. The construction industry is one of the largest CO₂ emitters in the world, producing up to 8% of the global CO₂ to produce cement. The use of sand largely depletes natural resources for the creation of mortars or concretes. This review explores the possibilities of incorporating waste glass into cement-based materials. It was found waste glass is unsuitable as a raw material replacement to produce clinker and as a coarse aggregate, due to a liquid state being produced in the kiln and the smooth surface area, respectively. Promising results were found when incorporating fine particles of glass in cement-based materials due to the favourable pozzolanic reaction which benefits the mechanical properties. It was found that 20% of cement can be replaced with waste glass of 20 μm without detrimental effects on the mechanical properties. Replacements higher than 30% can cause negative impacts as insufficient amounts of CaCO₃ remain to react with the silica from the glass, known as the dilution effect. As the fine aggregate replacement for waste glass increases over 20%, the mechanical properties decrease proportionally; however, up to 20% has similar results to traditionally mixes.

title: Linking land, river and moana: Collaborative research between Te Whakatōhea and Lincoln University within the coastal rohe

authors: Morris, Richard

abstract: In the eastern Bay of Plenty, where the land yields to the Pacific and the Waioeka and Ōtara Rivers meet Te Moana aToi (the Bay of Plenty), a research partnership is flourishing between Te Whakatōhea iwi, Lincoln University Centre of Excellence Designing Future Productive Landscape (DFPL), and Waikato University. This collaboration has grown over several years into a suite of multidisciplinary research projects focused on agricultural systems design, urban planning, and climate resilience. While distinct in their objectives, these research threads are united by a deeper, unavoidable theme: the interconnection between whenua (land), awa (river), and moana (sea). For Te Whakatōhea, these are not separate domains but a continuous space of identity, sustenance, and economy, an ethos that sits well with DFPL.
