title: An electronics Threshold-Concept Inventory: Assessment in the face of the dependency of concepts

authors: Scott, Jonathan B.

subjects: assessment

abstract: The Theory of Threshold Concepts (TCs), first articulated by Land and Meyer in 2003, provides educators in many disciplines with a tool to identify those special ideas that both define the characteristic ways of thinking of expert practitioners, and cause the greatest learning difficulties for students. Concept inventories are popular assessment tools, epitomized by the widely-accepted Force Concept Inventory of Hestenes et al., introduced circa 1992. It is a natural marriage to bring these two thrusts together to produce “Threshold-Concept Inventories”. We report ongoing work to develop and verify such a TC-inspired inventory assessment tool in the field of electronics and simple circuit theory. We identify the difficulty in the development of questions targeted at assessing understanding of single threshold concepts and present results in support of a strategy to deal with this.

title: ApproXFILTER - an approximative XML filter

authors: Michel, Yann-Rudolf

subjects: computer science

abstract: Publish/subscribe systems filter published documents and inform their subscribers about documents matching their interests. Recent systems have focussed on documents or messages sent in XML format. Subscribers have to be familiar with the underlying XML format to create meaningful subscriptions. A service might support several providers with slightly differing formats, e.g., several publishers of books. This makes the definition of a successful subscription almost impossible. We propose the use of an approximative language for subscriptions.We introduce the design our ApproXFILTER algorithm for approximative filtering
in a pub/sub system. We present the results of our analysis of a prototypical implementation.

title: Reconnecting whānau: Pathways to recovery for Māori with bipolar disorder

authors: Waitoki, Waikaremoana

subjects: mental health

abstract: While Māori are known to experience a higher burden of mental health and addiction problems compared to non-Māori (Baxter, 2008), little exploratory research has been conducted into Māori experiences of bipolar affective disorder. Bipolar disorder is at times regarded as a “life sentence”, with little hope of recovery. The recovery- focused mental health literature, however, argues wellness is achievable for even the most intractable conditions (Lapsley, Nikora, & Black, 2002; Mental Health Commission, 2001). The aim of this research was to gather information about the experiences of Māori who were diagnosed with bipolar affective disorder. Interviews were conducted with 22 Māori wāhine (women) and tāne (men), and using thematic analyses, themes relevant to their life stories were uncovered. This research sought to contribute to the realisation of Māori potential by explicitly shifting from deficit- focused frameworks to a focus on systemic factors that influenced Māori wellbeing. Highlights were that whānau (participants) who were connected with friends, partners and family were motivated to achieve wellness and to stay well.
