title: Food insecurity in urban New Zealand. The case of the Kopa family

authors: Graham, Rebekah Sarah

abstract: Poverty brings insecurity and chaos into the home, forcing families to develop strategies for navigating the difficulties of food insecurity. We document how one household, the Kopa family, responds to poverty in ad hoc and agentive ways that assist and hinder their attempts to keep themselves fed. This study is based on a series of eight qualitative interviews with family members, including photo-elicitation and go-along techniques, as well as extensive field notes from more casual research interactions such as shared meals. Our analysis demonstrates how food insecurity shapes this family’s culturally patterned social practices surrounding the procurement, consumption, and sharing of food.

title: An Interactive User Management System for Multilingual Documents: A case study of the Pei Jones collection

authors: Cader, Papitha

subjects: Greenstone Digital Library

abstract: Can general purpose DL software architecture be designed to provide a flexible environment that supports both the management and end-user roles through a single unified web interface? In particular we take the collected correspondence of the Māori scholar Dr. Pei Jones and undertake case study of how this approach can be applied in a practical way.

title: Structural changes as a result of processing in thermoplastic bloodmeal

authors: Verbeek, Casparus Johan R.

subjects: extrusion

abstract: Bloodmeal (BM) can be thermoplastically processed resulting in a material with good mechanical properties by using a correct combination of additives. In this article, combinations of water, sodium sulfite (SS), sodium dodecyl sulfate (SDS), and urea were compounded with BM, and water absorption, solubility, thermal stability, and protein secondary structure were assessed. Thermal stability of processed plastics was reduced when using 2 or 3 pphbm (parts per hundred parts BM) SS and 20 pphbm urea, mostly indicative of a reduction in covalent crosslinking. SS was required for chain mobility during processing, however, without sufficient plasticization degradation will occur instead of melt formation. SDS further improved processability and consolidation leading to increased water absorption and solubility, indicative of a reduction in chain interactions. It was found that BM proteins are highly denatured and thermoplastic processing reduced ordered structures further. Additional minor structural changes occurred as a result of reduced covalent and noncovalent interactions after processing. It was concluded that the increase in water absorption and solubility was due to changes in intermolecular and intramolecular interactions, rather than substantial structural changes.
