title: Thermal and Mechanical Properties of Bloodmeal-Based Thermoplastics Plasticized with Tri(ethylene glycol)

authors: Bier, James Michael

subjects: glass transitions

abstract: Thermoplastic protein produced from bloodmeal (BM) becomes brittle as moisture desorbs from the material. Tensile tests, DMA, DSC and WAXS are used to determine the effect of replacing water with TEG. Specimens containing 0–30 pphBM TEG and combined water and TEG content prior to extrusion of 60 pphBM are extruded, injection-moulded and conditioned. TEG increases the strain at break while reducing strength. 20 pphBM is chosen as an appropriate compromise between strength and ductility with a tensile strength of 6 MPa, a Young's modulus of 250 MPa, a toughness of 2.8 MPa and a strain at break of 0.53. When TEG is held at 20 pphBM and the amounts of other additives varied urea has the largest effect on conditioned properties, showing that H-bonding still dominates protein/protein

title: Keeping goods moving in the wake of a disaster: A qualitative study of intermodal transport

authors: L'Hermitte, Cécile

abstract: Purpose: This paper examines what facilitates the swift reconfiguration of freight movements across transport modes in the wake of a major disaster. Design/methodology/approach: A qualitative research approach focussing on the New Zealand (NZ) domestic freight transport operations in the wake of the 2016 Kaikōura earthquake is used with data collected through 19 interviews with 27 informants. The interviews are thematically analysed by using the framework method. 
Findings: The paper provides rich and detailed descriptions of the ability of a freight transport system to recover from a disaster through rapid modal shifts. This paper identifies nine factors enabling modular transport operations and highlights the critical role of physical, digital, operational and inter-organisational interconnectivity in the aftermath of a disaster. 
Originality/value: Although the management of freight disruptions has become a prevalent topic not only in industry and policy-making circles, but also in the academic literature, qualitative research focussing on the ability of commercial freight systems to adapt and recover from a disaster through rapid modal shifts is limited. This qualitative study sheds light on the mechanisms underlying the continuity of freight operations in the wake of a disaster and provides a comprehensive understanding of modular transport operations and the ability of freight systems to keep goods moving.

title: Defining indigenous trade: A working paper incorporating Māori and indigenous perspectives

authors: McLellan, Georgia

abstract: This working paper is part of a New Zealand Government–funded research project titled ‘Tauhokohoko: Enabling mana motuhake through Indigenous trade’ (Tauhokohoko), which was developed by the University of Waikato and Te Rōpū Taumata Charitable Trust (Te Taumata). The paper was prepared by the Tauhokohoko Research Aim 1.3 team and sets out a working definition of ‘Indigenous trade’.

The Tauhokohoko Research Aim 1.3 team acknowledges that the term ‘Indigenous’ can be problematic, since it collectivises the experiences of all Indigenous peoples. The project acknowledges the diverse realities of Indigenous peoples and strives to use the term in an inclusive way. Despite the existence of fraught relations between Indigenous peoples and postcolonial trade practices, Indigenous peoples have always had their own trade practices and relations grounded in Indigenous ways of being, knowing and doing. Within contemporary economies, Indigenous peoples are increasingly turning to international trade to meet their economic, social and cultural aspirations.

The Tauhokohoko Research Aim 1.3 team believes that Indigenous trade, when practiced in the right way, can be used as a tool for enhancing Indigenous self-determination and collective wellbeing. This paper outlines a tentative definition of ‘Indigenous trade’ for research purposes and provides grounded examples of Indigenous trade that fit within that tentative definition. The Tauhokohoko project is concerned primarily with the involvement of Indigenous peoples in international trade as a financial activity; however, the tentative definition encompasses financial, non financial, tangible and non-tangible forms of exchange. The paper ends by outlining the key literature that informs the working definition of ‘Indigenous trade’, including perspectives on the origins of international trade and Indigenous trade, international business and entrepreneurship, and Indigenous economies.
