title: Bioaccumulation of heavy metals in fishes from Taihu Lake, China

authors: Chi, Qiao-Qiao

subjects: fish

abstract: The Cr, Zn, Cu, Cd, Pb contents were determined in Cyprinus carpio Linnaeus, Carassius auratus Linnaeus, Hypophthalmichthys molitrix and Aristichthys nobilis, which were caught from Meiliang Bay, Taihu Lake, a large, shallow and eutrophic lake of China. The results showed that: (1) the Cr, Cu, Pb, Cd contents in the edible parts of the four fish species were much lower than Chinese Food Health Criterion (1994), but the Zn contents were higher than the Criterion; (2) Cd contents were the highest in the liver of fish, Pb contents were almost the same in all organs of fish, Cr contents mainly enriched in the skin and gonads, Zn contents were the highest in the gonad (♀), and Cu contents were the highest in the liver; (3) the total metal accumulation was the greatest in the liver and the lowest in the muscle. The total metal accumulation was the highest in C. auratus L. This investigation indicated that fish products in Taihu Lake were still safe for human consumption, but the amount consumed should be controlled under the Chinese Food Health Criterion to avoid excessive intake of Zn.

title: Building bridges: A transdisciplinary future for knowledge management

authors: Jones, Rachel

subjects: boundary object

abstract: Knowledge management (KM) is currently a fragmented field. It is characterised by a range of competing ontological approaches towards knowledge and its management, a consequence of KM's emergence from IS and its subsequent adoption and use in a wide range of management disciplines. Some KM scholars believe the future of KM lies in uniting these approaches by having KM achieve disciplinary status. This paper explores an alternative future for KM - it argues that KM could benefit from being the central focus of transdisciplinary research, rather than a discipline itself. Not to be confused with multi-, inter-, and post-disciplinary approaches, the discussion first carefully explains what is meant by transdisciplinarity. The paper then explores the advantages, as well as the challenges, of transdisciplinarity, before, finally, positioning KM as a potential boundary object of interest and import to many fields of study.

title: Bilingual behaviour checklists: initiating a student, teacher and parent partnership in behaviour management.

authors: Glynn, Ted

subjects: bilingual education

abstract: Three bilingual (Maori and English) behavioural checklists formed part of a project designed to facilitate student, teacher and whanau collaboration in overcoming behavioural difficulties experienced by Maori students, (Hei Awhina Matua). The checklists assessed rankings by 163 students, 21 teachers and 96 whanau members of (1) contexts in which problem behaviours occur, (2) specific problem behaviours and (3) specific most valued behaviours. Data were gathered in three schools: a mainstream intermediate school with a Māori medium syndicate of three classes, a rural Kura Kaupapa Maori (Maori-controlled total immersion school) and a bilingual contributing primary school. While the three schools differed markedly in location, size, and in the proportion of Maori students enrolled, the rankings of settings and behaviours by students, teachers and whanau in each school were highly similar. The paper discusses how these data contributed to the design and development of the Hei Awhina Matua video and training manual, and provided a first step towards a collaborative student teacher and parent partnership in the management of student behaviour.
