‘On the influence of the scientific societies of New Zealand on the character of the nation’ - Collecting and identity at the Hawke’s Bay Philosophical Institute museum, 1874–1899

This paper explores the collection and collecting activity of the Hawke’s Bay Ph ilosophical Institute of Napier, New Zealand. It examines the development of the Institute’s museum and considers the motivations, intentions and interests of the collectors and their activity within the broader scientific and museum context. The work of two significant collectors is examined in detail: William Colenso, FLS, FRS, missionary, explorer and enthusiastic botanist, who engaged in over fifty years of correspondence and botanical exchange with Sir Joseph Hooker at Kew Gardens; and Augustus Hamilton, the curator of the museum who later became Director of New Zealand’s national collection at the Colonial Museum in Wellington. Through consideration of the Institute’s activities during the period 1874 to 1899, it is proposed that within the collection, the emergence of a distinct local identity can be discerned, during the early colonial period of Hawke’s Bay.

A framework for considering cross-cultural exchanges as a way to develop reasoning about environmental socio-scientific issues

This study analyses the evolution of socioscientific reasoning on sustainability, of French and Australian tertiary students exchanging ideas on a digital platform, concerning local (Australian, French) environmental SSIs, and global environmental SSIs. We explore how the exchange of arguments from various disciplinary and cultural perspectives, can promote reasoning about complex problem-situations in the environment. We develop a framework of reasoning, and show how it enables a productive analysis of the nature of the exchanges, and the quality of reasoning. We argue that such a strategy may improve epistemological training on the nature of science, and citizenship.

Teaching the scientific method in the curriculum

 In chemistry education, students not only learn chemical knowledge and skills, but about the culture of chemistry – how scientists think about, and practise, chemistry. Students often learn that science is practised according to the “scientific method”, which is a model of scientific discovery, expounded by science historians and philosophers. The idealised “scientific method” has a number of steps: the collection of information about a phenomenon; the development of a hypothesis to explain those observations; an experiment to test a prediction that arises from the hypothesis, perhaps including more observations and collection of more information; improvement of the hypothesis; and so on.

The problem is that students (and even some science professionals) often do not understand the philosophy behind the scientific method and paradoxically, the scientific method does not seem to apply to most careers in science. The true nature of science is that concepts have been developed though variants of the “scientific method”, and that a process of testing the predictive value of these concepts has lead to advances in that conceptual knowledge. Hence the “scientific method” applies to the development of scientific ideas, not necessarily to the work of all scientists. It is not whether we personally use the scientific method in our day-today work, but how we use, apply, think about and communicate scientific knowledge and skills that makes us chemists.

Professional legal education reviews : too many 'what's, too few 'how's

Former colonies of the British Empire, Hong Kong and Australia inherited the common law system and the basic structure of legal education and training from England and Wales and remain the closest siblings in terms of proximity in distance and the high degree of similarity between their respective frameworks for legal education and training. This article first summarizes the major reviews of legal education and training in these three jurisdictions: England and Wales, Australia and Hong Kong over the last four decades and argues that while these reviews are keen on investigating ‘what’ is lacking in the curriculum and ‘what’ needs to be changed to equip graduates for the challenges of the day, they do not seem to have shown the same level of enthusiasm in identifying ‘how’ the intended outcomes prescribed can be achieved. Nevertheless, law schools in these jurisdictions recently began to tap on, and combine with the improved classroom pedagogy, clinical legal education and internship, innovative teaching tools and solutions in an attempt to deliver more enhanced learning experience to students. The article examines the role ascribed to technology in legal education and training with a particular reference to SimPLE, a e-learning platform developed in England and Wales which has been put to use in Australia as well, and the reform initiatives taken, and planned to be taken, by the Department of Professional Legal Education at the University of Hong Kong in its Postgraduate Certificate in Laws programme. This article concludes by pointing out the importance of collaboration among stakeholders including teachers, university administration and the legal profession in effecting a more active role of technology in legal education and training of today.

An epidemiological analysis of the 'autism as mercury poisoning' hypothesis

Where direct experimental research into a causal hypothesis of a disease is impossible due to ethical and practical considerations, epidemiological inference is the accepted route to establishing cause. Therefore, to examine the autism as mercury poisoning hypothesis, this paper reviews the existing scientific literature within the context of established epidemiological criteria and finds that the evidence for a causal relationship is compelling. Exposure to mercury (via vaccines and maternal dental amalgam) in utero and during infant years is confirmed; mercury poisoning is known to cause symptoms consistent with autism; animal modeling supports the link and, critically, mercury levels are higher in both the urine and blood of autistic children than in non-autistic peers. Analogous to epidemiological evidence of the smoking–lung cancer relationship, a mercury–autism relationship is confirmed. The precautionary principle demands that health professionals not take an action if there is suspicion that the action may cause severe or lifelong health effects: it does not require certainty. Therefore, given the severity, devastating lifelong impact and extremely high prevalence of autism, it would be negligent to continue to expose pregnant and nursing mothers and infant children to any amount of avoidable mercury.

Scientific foundations for an IUCN red list of ecosystems

 An understanding of risks to biodiversity is needed for planning action to slow current rates of decline and secure ecosystem services for future human use. Although the IUCN Red List criteria provide an effective assessment protocol for species, a standard global assessment of risks to higher levels of biodiversity is currently limited. In 2008, IUCN initiated development of risk assessment criteria to support a global Red List of ecosystems. We present a new conceptual model for ecosystem risk assessment founded on a synthesis of relevant ecological theories. To support the model, we review key elements of ecosystem definition and introduce the concept of ecosystem collapse, an analogue of species extinction. The model identifies four distributional and functional symptoms of ecosystem risk as a basis for assessment criteria: a) rates of decline in ecosystem distribution; b) restricted distributions with continuing declines or threats; c) rates of environmental (abiotic) degradation; and d) rates of disruption to biotic processes. A fifth criterion, e) quantitative estimates of the risk of ecosystem collapse, enables integrated assessment of multiple processes and provides a conceptual anchor for the other criteria. We present the theoretical rationale for the construction and interpretation of each criterion. The assessment protocol and threat categories mirror those of the IUCN Red List of species. A trial of the protocol on terrestrial, subterranean, freshwater and marine ecosystems from around the world shows that its concepts are workable and its outcomes are robust, that required data are available, and that results are consistent with assessments carried out by local experts and authorities. The new protocol provides a consistent, practical and theoretically grounded framework for establishing a systematic Red List of the world’s ecosystems. This will complement the Red List of species and strengthen global capacity to report on and monitor the status of biodiversity.

Cross cultural exchange to support reasoning about socio-scientific sustainability issues

In this article, we describe a project on reasoning about socio-scientific issues (SSIs), involving French and Australian pre-service science teachers engaged in on-line discussion and development of a wiki. In the research, we developed frameworks for looking at the quality of reasoning about 'socially acute' sustainability questions. We found the level of reasoning was enhanced by the cross-cultural exchange, and identified the importance of context in framing reasoning quality. We argue that science teachers could effectively adapt this approach to develop students' scientific literacy and embed the 'science as a human endeavour' strand of the Australian Curriculum in their practice.
