Values in science, environmental education and teacher education

The aim of this chapter is to establish values as a key component of science and environmental education, consistent with the troika framework, and to explore the implications of this for teacher education. In the chapter, we review research that has increasingly placed values at the centre of the process of learning science, and central also in framing students' responses to school science. We then present findings from three projects that explore the relationship of values to teaching and learning science: first, an exploration of the pedagogies of effective teachers of science; second,an environmental education project in which students explore science and sustainability ideas in the context of a community exchange program in Mexico and Alaska; and, third, a teachcr education initiative focused on place-based education. In the chapter, we argue that learning science and engaging with the environment entails pedagogies that link conceptual learning, values and community.

Measuring the performance of a regional cluster in innovation facilitation

Regional industry clusters have been promoted for several years as effective mechanisms to assist firms become more innovative and more competitive. But do they really achieve this goal, and more importantly, just how should an assessment of cluster performance in supporting and facilitating innovation within its members, be undertaken? In this paper we report on a study of a regional IT cluster in Western Sydney, Australia, develop some criteria for assessing the innovation facilitation performance of industry clusters, and discuss the cluster in relation to these criteria. We suggest that engagement with a cluster may enhance the innovation capacity of a firm, and the type of required innovation support varies significantly with the maturity and absorptive capacity of individual firms.

A learning laboratory approach for business improvement : the case of discontinuous innovation

This paper considers the current situation within Australian manufacturing SMEs and their approaches to innovation and international competitive advantage. Using the viewpoint and language of complexity theory, we consider the variety of possibilities available to SMEs in this area. We then consider a particular international project on Discontinuous Innovation, how this has been deployed in Europe and Australia and the knowledge gained from our interactions with Australian SMEs to date around this project. Finally we consider the general development of a “Learning Laboratory” approach to working with SMEs and the differences required to make such approach successful in Europe and in different settings in Australia.

Lipid composition of Australian pork cuts 2005/2006

A study of the cholesterol content and fatty acid composition of fresh retail Australian pork was undertaken to determine whether new breeding, feeding and processing methods had resulted in any compositional changes in fresh pork in the market place since surveys undertaken in previous decades. Samples of 13 popular pork cuts were purchased from randomly selected supermarkets and butchers’ stores in urban areas across the socioeconomic scale in three States of Australia, and analysed, separable fat and separable lean, in late 2005 and early 2006. Variability was low across States for saturated and monounsaturated fatty acids, but more pronounced for polyunsaturated acids. The separable lean portions of all pork cuts contained levels of n-3 fatty acids and conjugated linoleic acid (C18:1c9t11) in measurable but not nutritionally claimable amounts, whilst total trans fatty acid levels were very low. There appeared to be some differences in fatty acid composition across States that may have resulted from feeding method. Cholesterol contents were similar to levels in the 80s and 90s for separable lean pork tissue, but presently are lower for separable fat tissue than for separable lean.

Surveillance of wild birds for avian influenza virus

Recent demand for increased understanding of avian influenza virus in its natural hosts, together with the development of high-throughput diagnostics, has heralded a new era in wildlife disease surveillance. However, survey design, sampling, and interpretation in the context of host populations still present major challenges. We critically reviewed current surveillance to distill a series of considerations pertinent to avian influenza virus surveillance in wild birds, including consideration of what, when, where, and how many to sample in the context of survey objectives. Recognizing that wildlife disease surveillance is logistically and financially constrained, we discuss pragmatic alternatives for achieving probability-based sampling schemes that capture this host-pathogen system. We recommend hypothesis-driven surveillance through standardized, local surveys that are, in turn, strategically compiled over broad geographic areas. Rethinking the use of existing surveillance infrastructure can thereby greatly enhance our global understanding of avian influenza and other zoonotic diseases.

Hampered foraging and migratory performance in swans infected with low-pathogenic avian influenza A virus

It is increasingly acknowledged that migratory birds, notably waterfowl, play a critical role in the maintenance and spread of influenza A viruses. In order to elucidate the epidemiology of influenza A viruses in their natural hosts, a better understanding of the pathological effects in these hosts is required. Here we report on the feeding and migratory performance of wild migratory Bewick's swans (Cygnus columbianus bewickii Yarrell) naturally infected with low-pathogenic avian influenza (LPAI) A viruses of subtypes H6N2 and H6N8. Using information on geolocation data collected from Global Positioning Systems fitted to neck-collars, we show that infected swans experienced delayed migration, leaving their wintering site more than a month after uninfected animals. This was correlated with infected birds travelling shorter distances and fuelling and feeding at reduced rates. The data suggest that LPAI virus infections in wild migratory birds may have higher clinical and ecological impacts than previously recognised.

Achieving effective cross-sector R&D collaboration : a proposed management framework

Cross‐sector R&D collaboration, as exemplified by the Australian Cooperative Research Centre Program, is increasing in incidence due to government policies and corporate practices. While the benefits of such collaborations are widely promoted, the resulting relationships (typically involving companies, universities and public sector research agencies) can be difficult to manage so as to achieve beneficial outcomes for all partners. A management framework for establishing these collaborations is proposed. This framework is based on four tensions in cross‐sector collaborations, and it takes the perspective that knowledge created for mutual benefit is the common focus of these ventures.

The disappearing mammal fauna of northern Australia : context, cause, and response

This article provides a context to, attempts an explanation for, and proposes a response to the recent demonstration of rapid and severe decline of the native mammal fauna of Kakadu National Park. This decline is consistent with, but might be more accentuated than, declines reported elsewhere in northern Australia; however, such a comparison is constrained by the sparse information base across this region. Disconcertingly, the decline has similarities with the earlier phase of mammal extinctions that occurred elsewhere in Australia. We considered four proximate factors (individually or interactively) that might be driving the observed decline: habitat change, predation (by feral cats), poisoning (by invading cane toads), and novel disease. No single factor readily explains the current decline. The current rapid decline of mammals in Kakadu National Park and northern Australia suggests that the fate of biodiversity globally might be even bleaker than evident in recent reviews, and that the establishment of conservation reserves alone is insufficient to maintain biodiversity. This latter conclusion is not new; but the results reported here further stress the need to manage reserves far more intensively, purposefully, and effectively, and to audit regularly their biodiversity conservation performance.

Repeatable sediment associations of burrowing bivalves across six European tidal flat systems

Burrowing bivalves are associated with particular sediment types within sedimentary systems. The degree to which bivalve sediment associations are repeatable across systems has seldom been investigated. To investigate whether such repeatability exists across tidal flats, we compared adult and juvenile distributions of 3 bivalve species (Cerastoderma edule, Scrobicularia plana, Macoma balthica) across 6 European tidal flats. Across systems, the adult bivalves showed fairly repeatable distributions, with C. edule occurring in sandy sediments and M. balthica and S. plana occurring in muddy sediments. Exceptions were observed in systems composed primarily of muddy sediments (Aiguillon Bay and Marennes-Oléron Bay) and the Dutch Wadden Sea. Interestingly, juveniles and adults of C. edule and S. plana showed similar distributions across systems. M. balthica juveniles and adults showed habitat separation in 3 of the 6 studied systems; in 2 of these, it has been shown previously that juvenile M. balthica settle in mud at high tidal levels and migrate to lower sandier flats later in life. The high occurrence of juvenile M. balthica towards high sandy flats in Mont Saint-Michel Bay suggests that juveniles might choose high tidal flats rather than muddy sediments per se. A repeatable association in adults and juveniles with respect to sediment could suggest that juveniles actively settle in the proximity of the adults and/or that juveniles settling away from the adults incur a higher mortality due to either predation, physiological stress, or other factors.
