title: A new substrate for sampling deep river macroinvertebrates

authors: Collier, Kevin J.

subjects: Hester-Dendy

abstract: We compared macroinvertebrate communities colonising multiplate samplers constructed from perspex or tempered hardboard (wood) with an alternative artificial substrate constructed from folded coconut fibre matting (coir) enclosed in nylon netting. Substrates were incubated for 62 days over January to March 2007 at six sites over 240 km along the Waikato River. The three substrates supported similar numbers of invertebrate taxa (27 - 29 taxa), but coir samples contained 71% of total invertebrate numbers from all substrates combined, compared with <17% for each type of multiplate sampler. Coir faunas were heavily dominated by the hydrobiid snail Potamopyrgus (84 % of numbers), and this taxon along with the amphipod Paracalliope comprised 58 - 66 % of invertebrates on both types of multiplate samplers. Analysis of a Bray-Curtis matrix suggested statistically significant differences in percent community composition between coir samplers and each type of multiplate sampler over the late summer study period. Densities per cm3 of Oligochaeta, Mollusca, and "other worms" (Platyhelminthes, Rhabdocoela, Nemertea and Hirudinea combined) were significantly higher in coir samples than one or both of the multiplate samplers. Results suggest coir samplers may provide a useful supplement to multiplate samplers for deep river invertebrate studies by collecting a different range of taxa, including those favouring cover and characteristic of depositional environments.

title: Imbalance in surrender: the backing of warrants procedure with Australia under Part 4 of the Extradition Act 1999

authors: Butler, Rynae Daphne

subjects: backed warrant procedure

abstract: The backing-of-warrants is a fast-track procedure for extradition regulated under Part 4 of the Extradition Act 1999.  This thesis critically scrutinises a recent review of the legislation by the Law Commission as it relates to the impact of its proposed new Act on the current backed-warrant procedure, particularly as it relates to Australia.  The Commission’s proposal that its new Act will achieve the Commission’s objective to “strike the necessary and appropriate balance between protecting the rights of those whose extradition is sought and providing an efficient mechanism for extradition” will be analysed and critiqued.    It will be shown that, the Commission has tipped the balance towards the liberty interests of the requested person, when it proposed to increase the breadth of grounds by which the courts may refuse surrender under a new “unjust or oppressive” provision. As a consequence, the proposed legislative provisions may risk breaching the doctrine of comity and frustrating the backed-warrant procedure. This thesis further posits that comity should not be over-emphasised, particularly as the Commission has not at all or has inadequately considered the disparity that exists between the way comity is applied in practise by the Australian and New Zealand courts. As a consequence, the proposed less onerous test for Australia, is unjustified. While the Commission’s proposal gives weight to the growing importance of human rights as a determining factor in surrender nevertheless, the Commission’s proposals lack coherency and fail to delineate between the standard procedure and the backed-warrant procedure. In absence of any evidence that the efficacy of the backed-warrant procedure is wanting, the impact of the Commission’s proposals, are unlikely therefore to achieve the balance it strives to achieve.   The argument put here is that there is a strong principled case for strengthening human rights protections in the current backed-warrant procedure. In that regard, this thesis advances the proposition that in combination, the Commission’s New Zealand Bill of Rights proposal and a role for a proposed central authority - subject to reconceptualising comity in this context to one that includes a human rights component.  To that end, this thesis advocates replacing the balancing act paradigm that purports to reconcile the competing interests underpinning extradition with an assessment of human rights as a primary determining factor in surrender at both the initial stages and latter stages of the backed-warrant procedure. This model, as proposed, will maintain the fast-track nature of the backed-warrant procedure as it would allow the judiciary to differentiate risk between low-level and gross forms of human rights violations or abuse.  Finally, this thesis posits that the jurisprudential acceptance in the courts of the extraterritorial effect of the New Zealand Bill of Rights Act 1990 in relation to Australian Police conduct in New Zealand merits attention.

title: Education leaders can reduce educational disparities

authors: Bishop, Russell

subjects: education

abstract: This chapter is about how education leaders can act to reduce educational disparities for indigenous and other minoritized peoples through strategic goal setting, supporting effective pedagogies of relations, promoting distributed leadership, enacting inclusivity, using evidence and owning the need for reform. Examples are drawn from a large-scale, theory-based education reform project called Te Kotahitanga which is currently running in 50 secondary schools in New Zealand. Developing a model for effective leadership needs to commence with the understanding that the key to change is teacher action supported by responsive structural reform (Elmore 2004). In our earlier work (Bishop et al. 2003, 2007) we investigated what effective teacher action looks like. This chapter presents a model of what “responsive structural reform” looks like in practice and what leaders need to do to implement and sustain gains made in student performance at the classroom, school and system-wide levels.
