title: Quantitative estimates of fish abundance from boat electrofishing

authors: Hicks, Brendan J.

subjects: biology

abstract: Multiple removals by boat electro-fishing were used to estimate fish populations in non-wadeable habitats in New Zealand lakes and rivers. Mean capture probability was 0.47±h0.10 (± 95% CI) from 35 population estimates made with 2-7 successive removals. The relationship between the population estimate from the Zippin method (Y)and the number of fish caught in the first removal (X) was significant (adjusted r2=0.84, P<0.001; Figure 2). The least-squares regression was Y = 1.55X 1.23. Mean density ± 95% confidence interval for 13 fishing occasions was 30±27 fish 100 m-
2. Mean biomass of fish for sites was 78±39 g m-2 (range 29 to 245 g m-2). Koi carp comprised the largest proportion of the fish biomass wherever they were present. The high biomasses of koi carp estimated in these results (mean 56±33 g m-2) suggest that they can reach problematic abundances in New Zealand. Bioniass of spawning koi carp can exceed 400 g m-2.

title: There's no place like home: Is our preference for familiar surroundings a bias?

authors: Weijers, Dan M.

abstract: Drawing on experimental and traditional philosophical methods, several researchers have argued that our judgments about the relative value of different lives are often affected by status quo bias. Status quo bias – the irrational overvaluing of the status quo – appears to make our comparative judgments of our current life with different, and especially radically different, kinds of lives unhelpful. If true, this finding has significant implications for philosophy in several areas, including wellbeing, moral theory, and any value-based theorising about home. In this presentation, I will present the results of experiments on different versions of Nozick’s experience machine scenario. The different versions of the scenario were designed to tease out what it is that we value about the status quo, enabling me to establish whether our high valuing of home is more to do with our personal relationships, familiarity with our surroundings, or fear of the unknown. The experiments included gathering individual characteristics of participants, so that many possibly confounding factors could be analysed. The main message from the results is that for many people, going home means going to where the people they love are.

title: Conscientisation and Resistance: Experiences from implementing a culturally responsive pedagogy of relations

authors: Lawrence, Dawn Cherie

subjects: culturally responsive pedagogy of relations

abstract: Consciousness of being part of a particular hegemonic force (that is to say,political consciousness) is the first stage towards a further progressive self –conscious in which theory and practice will finally be one. (Hoare & Smith,1971, p. 333)

Bishop, Berryman, Tiakiwai and Richardson, (2003) state that effective teachers of Māori students “positively and vehemently reject deficit theorizing as a means of explaining Māori students’ educational achievement” (p.95). This fundamental tenet of the Te Kotahitanga Effective Teaching Profile (ETP) moves beyond simply refraining from publicly articulating discourses that pathologise Māori students and their whānau (Bishop et al., 2003; Bishop & Berryman, 2006; Bishop, Berryman, Cavanagh, & Teddy. 2007). For many teachers it is a challenging, ongoing transformative process of critical self-reflection, which touches the very core of their own culture and identity.

This thesis contends that by working to discursively position themselves within a culturally responsive pedagogy of relations, teachers develop classroom practices that have been shown to positively affect outcomes for Māori students. It goes on to suggest that such discursive repositioning might be seen as praxis, with the potential to transform the inequities experienced by Māori within mainstream educational settings. With this understanding, the culture and leadership approach of the school context becomes a greater influence on teachers’ capacity to realize their agency within this pedagogy than any characteristic of the individual.
