title: Equal partners? Improving the integration between DSpace and Symplectic Elements

authors: Miller, Kate

subjects: Integration between DSpace and Symplectic Elements

abstract: While self-submission by academics was regarded as the ideal way to add content to Open Repositories in the early days of such systems, the reality today is that many institutional repositories obtain their content automatically from integration with research management systems. The institutional DSpace repositories at Auckland University of Technology (AUT) and at the University of Waikato (UoW) were integrated with Symplectic Elements in 2010 (AUT) and in 2014 (UoW). Initial experiences at AUT suggested a mismatch between the interaction options offered to users of Symplectic Elements on one hand and the actions available to repository managers via the DSpace review workflow functionality on the other hand. Our presentation explores these mismatches and their negative effects on the repository as well as on the user experience. We then present the changes we made to the DSpace review workflow to improve the integration. We hope that our experiences will contribute to an improvement in the integration between repository software and research management systems.

title: Oxytocin receptor blockade reduces acquisition but not retrieval of taste aversion and blunts responsiveness of amygdala neurons to an aversive stimulus

authors: Olszewski, Pawel K.

subjects: anorexia

abstract: When gastrointestinal sickness induced by toxin injection is associated with exposure to novel food, the animal acquires a conditioned taste aversion (CTA). Malaise is accompanied by a surge in oxytocin release and in oxytocin neuronal activity; however, it is unclear whether oxytocin is a key facilitator of aversion or merely its marker. Herein we investigated whether blockade of the oxytocin receptor with the blood–brain barrier penetrant oxytocin receptor antagonist L-368,899 is detrimental for the acquisition and/or retrieval of lithium chloride (LiCl)-dependent CTA to a saccharin solution in mice. We also examined whether L-368,899 given prior to LiCl affects neuronal activity defined through c-Fos immunohistochemistry in select brain sites facilitating CTA acquisition. L-368,899 given prior to LiCl caused a 30% increase in saccharin solution intake in a two-bottle test, but when the antagonist was administered before the two-bottle test, it failed to diminish the retrieval of an existing CTA. LiCl administration increased c-Fos expression in the hypothalamic paraventricular and supraoptic nuclei, area postrema, nucleus of the solitary tract and basolateral and central (CNA) nuclei of the amygdala. L-368,899 injected before LiCl reduced the number of c-Fos positive CNA neurons and brought it down to levels similar to those observed in mice treated only with L-368,899. We conclude that oxytocin is one of the key components in acquisition of LiCl-induced CTA and the aversive response can be alleviated by the oxytocin receptor blockade. Oxytocin receptor antagonism blunts responsiveness of CNA to peripherally injected LiCl.

title: How Māori precariate families navigate social services

authors: King, Delta

abstract: We are living in a period in which the increasingly precarious nature of employment and welfare support systems has dramatically amplified the hardships faced by many people.¹ Correspondingly, much still needs to be written about the rise of the precariat. ² International literature asserts that post World War II paid employment was commonly full-time and secure up until the 1970s, when the rise of more insecure work increased as neoliberal policies and globalisation began dominating public deliberations regarding work and social life. ³ Subsequent recessions across many OECD countries contributed to labour market transformations back towards increased 'flexibility' and- the casualisation of employment. These labour market shifts have resulted in insecure work and income situations for many households, which for some means frequent cycles of paid employment and welfare dependency. People experiencing such insecure employment face insecure and unliveable incomes while grappling with inadequate state support - these are the people increasingly known as 'the precariat'.
