title: Phylogenetic delineation of the novel phylum armatimonadetes (former candidate division OP10) and definition of two novel candidate divisions

authors: Lee, Kevin Chien-Yu

abstract: Small-subunit (SSU) rRNA gene sequences associated with the phylum Armatimonadetes were analyzed using multiple phylogenetic methods, clarifying both the phylum boundary and the affiliation of previously ambiguous groupings. Here we define the Armatimonadetes as 10 class-level groups and reclassify two previously associated groups as candidate divisions WS1 and FBP

title: Thermally resolved synchrotron FT-IR microscopy of structural changes in bloodmeal-based thermoplastics

authors: Bier, James Michael

subjects: secondary structure estimation

abstract: Synchrotron FT-IR micro-spectroscopy was used to determine thermally induced structural changes in thermoplastic protein produced from bloodmeal after mixing with sodium sulphite, sodium dodecyl sulphate, urea, tri-ethylene glycol and water. Changes in protein secondary structure at elevated temperature were assessed using second derivative peak height ratios in the amide III region (1,200–1,330 cm⁻¹) and compared with DSC and DMA results over the same temperature range. The results show an increase in ordered β-sheet structures with temperature at the expense of random coils, and that these β-sheets do not melt in the temperature range up to extrusion temperature of 120 °C. The implication of this is that during melt processing, β-sheet clusters may remain intact, similar to dispersed particulate fillers.

title: Te Mauri o te Kaitiaki - Exploring Te Ao Māori in environmental relations and kaitiakitanga  in Aotearoa New Zealand

authors: Wareka, Mona-Lisa

subjects: Te Ao Māori

abstract: Indigenous environmental empowerment is on the rise as humans look at ways to slow the adverse effects of anthropogenic environmental degradation. In the context of Aotearoa New Zealand, the concept and practice of ‘kaitiaki’ and ‘kaitiakitanga’, respectfully, play a significant role in the co-existence of Māori with the natural world. Previous research shows the innate connections and responsibilities encompassed in being kaitiaki which extend beyond the human element to encompass nonhumans and spiritual manifestations. This research aims to illustrate how Māori use cultural values, concepts and practices in local-level conservational practices through ethnographic research in Matapōuri. I investigate the conflicts and convergences of a rāhui recently placed on two cultural significant areas to the local hapū, and through this, I analyse the practical and spiritual application of kaitiakitanga. Based on this ethnography, I discuss a model for relating environmental degradation with the wellbeing of Māori within Aotearoa New Zealand today. Here, I wish to highlight the ecological and cultural threats present from continuing in the current system. Lastly, I argue that the assertion of kaitiakitanga at the local-level is also an assertion of Indigenous autonomy for Māori and the environment.
