title: Hiding in plain sight: identifying partner stalking in intimate partner violence episodes reported to New Zealand Police

authors: Tomkins, Jordan

abstract: In relationships characterised by current or previous intimate partner violence (IPV), partner stalking is a commonly occurring phenomenon. In this study, we examined police-recorded partner stalking in IPV episode reports across 1150 cases to (a) consider the overlap between IPV and partner stalking, and the relevance of the aggressor and victim’s relationship phase to defining partner stalking; and (b) contribute empirical evidence about partner stalking prevalence rates and identification rates by police and victims. A secondary aim involved exploring possible differences between IPV cases with and without partner stalking. Although few police or victims explicitly used the label ‘stalking', we identified evidence of partner stalking within one in every seven IPV cases reported to New Zealand Police. Further, this study contributed novel analysis about relationship dynamics by adding an on–off relationship phase to the typically dichotomised categories of intact and separated relationships. In turn, we identified partner stalking relatively rarely within intact relationships; and significantly more frequently, and at similar rates, across both the separated and on–off relationship phases. Finally, we discuss implications for defining the overlap between IPV and partner stalking, police practice, and future research.

title: Enzyme activity below the dynamical transition at 220 K

authors: Daniel, Roy M.

abstract: Enzyme activity requires the activation of anharmonic motions, such as jumps between potential energy wells. However, in general, the forms and time scales of the functionally important anharmonic dynamics coupled to motion along the reaction coordinate remain to be determined. In particular, the question arises whether the temperature-dependent dynamical transition from harmonic to anharmonic motion in proteins, which has been observed experimentally and using molecular dynamics simulation, involves the activation of motions required for enzyme function. Here we present parallel measurements of the activity and dynamics of a cryosolution of glutamate dehydrogenase as a function of temperature. The dynamical atomic fluctuations faster than ~100 ps were determined using neutron scattering. The results show that the enzyme remains active below the dynamical transition observed at ~220 K, i.e., at temperatures where no anharmonic motion is detected. Furthermore, the activity shows no significant deviation from Arrhenius behavior down to 190 K. The results indicate that the observed transition in the enzyme's dynamics is decoupled from the rate-limiting step along the reaction coordinate.

title: Māori academic success: Why the deficit perspectives?

authors: Aporosa, S. 'Apo'

subjects: Māori

abstract: Academics have long discussed the power of communication to both motivate and discourage. Concerning education, Paulo Freire (1997) had explained the dialogical learning process and the empowerment that comes from the inclusion of student knowledge. Alternatively, Carlson & Dimitriadis (2003) describe disempowerment and underachievement among Afro-American students resulting from societal expectations that they will fail. In a recent education environment scan focused on the Waikato-Tainui rohe, 28 kaupapa Māori education providers were identified as sites of high educational success, with one described as “outshining private schools and bucking national trends” (Carson, 2013). This aside, perceptions of generalized educational failure among Māori are commonplace in Aotearoa New Zealand. These impressions are fed by the media, the Ministry of Education (MOE) and in some cases, academic publications. This paper discusses the power of deficit models and counter-narratives to academic underachievement. This will be juxtaposed with commentary on why some students and their education providers within the Waikato-Tainui rohe appear to be unaffected by these counter- narratives and deficit theorizing.
