Building professional capital : New Zealand social workers and continuing education

In a qualitative study of the engagement of New Zealand social workers in continuing professional education the construct "professional capital", a form of symbolic capital, explains complex links between perceived status within institutional settings and the aspirations of practitioners. Strategies for developing greater engagement in scholarship and research are recommended.

Reconstructing violent rural masculinities : responding to fractures in the rural gender order in Australia

Men's violence against women is higher in rural communities compared to urban areas and many writers have identified the increased vulnerability of women in rural areas when addressing men's violence. This article will explore the implications of the emerging scholarship on rural masculinities for understanding how rurality invokes different modes of masculinity associated with men's violence in the context of rural restructuring. While the socio-cultural aspects of rural areas generate stronger enforcement of gender roles that perpetuate gender inequality, rural restructuring challenges dominant forms of masculinity, and this has contradictory consequences for reconstructing masculinities. Consequently, while many rural men are endeavouring to preserve traditional masculinity in the face of the rural crisis, other men are exploring alternative masculinities that are incompatible with men's violence against women.

Australian universities, government research and the application of climate change knowledge in Australian coastal zone management

One of the key issues in Australia for sustainable management of the coastal zone is that the science of climate change has not been widely used by decision-makers to inform coastal governance. There exist opportunities to enhance the dialogue between knowledge-makers and decision-makers, and universities have a key role to play in researching and fostering better linkages. At the heart of these linkages lies the principle of more informed engagement between historically disparate groups. In Australia, the new ‘Flagship’ research programme, funded by the Commonwealth Scientific and Industrial Research Organization (CSIRO), emphasizes their partnering with universities in a more systematic and collaborative manner than previously achieved in such research projects. In order to address sustainability in general and coastal adaptation to climate change in particular, interdisciplinary learning needs to occur between the social and natural sciences; also, transdisciplinary understanding of that interaction needs to be fully developed. New methods of communicative engagement such as computer visualizations and animations, together with deliberative techniques, can help policy-makers and planners reach a better understanding of the significance of the science of climate change impacts on the coast. Deeper engagement across historically disparate groups can lead to the development of epistemological and methodological synergies between social and natural scientists, adaptive learning, reflexive governance, and greater analytical and deliberative understanding among scientists, policymakers and the wider public. This understanding can lead in turn to enhance coastal governance for climate adaptation on the coast.

New scalar politics : implications for education policy

This paper argues that globalisation has implications for research and theory in the social sciences, demanding that the social no longer be seen as homologous with nation, but also linked to postnational or global fields. This situation has theoretical and methodological implications for comparative education specifically focused on education policy, which traditionally has taken the nation-state as the unit of analysis, and also worked with 'methodological nationalism'. The paper argues that globalisation has witnessed a rescaling of educational politics and policymaking and relocated some political authority to an emergent global education policy field, with implications for the functioning of national political authority and national education policy fields. This rescaling and this reworking of political authority are illustrated through two cases: the first is concerned with the impact of a globalised policy discourse of the ‘knowledge economy’ proselytised by the OECD and its impact in Australian policy developments; the second is concerned explicitly with the constitution of a global education policy field as a commensurate space of equivalence, as evidenced in the OECD’s PISA and educational indicators work and their increasing global coverage. The paper indicatively utilises Bourdieu’s ‘thinking tools’ to understand the emergent global education policy field and suggest these are very useful for doing comparative education policy analysis.

Strategic male signalling effort in a desert-dwelling fish

Males often use elaborate courtship displays to attract females for mating. Much attention, in this regard, has been focused on trying to understand the causes and consequences of signal variation among males. Far less, by contrast, is known about within-individual variation in signal expression and, in particular, the extent to which males may be able to strategically adjust their signalling output to try to maximise their reproductive returns. Here, we experimentally investigated male courtship effort in a fish, the Australian desert goby, Chlamydogobius eremius. When offered a simultaneous choice between a large and a small female, male gobies spent significantly more time associating with, and courting, the former, probably because larger females are also more fecund. Male signalling patterns were also investigated under a sequential choice scenario, with females presented one at a time. When first offered a female, male courtship was not affected by female size. However, males adjusted their courtship effort towards a second female depending on the size of the female encountered previously. In particular, males that were first offered a large female significantly reduced their courtship effort when presented with a subsequent, smaller, female. Our findings suggest that males may be able to respond adaptively to differences in female quality, and strategically adjust their signalling effort accordingly.

The interval between sexual encounters affects male courtship tactics in a desert-dwelling fish

Courtship displays are often important in determining male mating success but can also be costly. Thus, instead of courting females indiscriminately, males might be expected to adjust their signalling effort strategically. Theory, however, predicts that such adjustments should depend on the rate with which males encounter females, a prediction that has been subject to very little empirical testing. Here, we investigate the effects of female encounter rate on male courtship intensity by manipulating the time interval between sequential presentations of large (high quality) and small (low quality) females in a fish, the Australian desert goby Chlamydogobius eremius. Males that were presented with a small female immediately after a large female reduced their courtship intensity significantly. However, males courted large and small females with equal intensity if the interval between the sequential presentations was longer. Our results suggest that mate encounter rate is an important factor shaping male reproductive decisions and, consequently, the evolutionary potential of sexual selection.

Ranking method for optimizing precision/recall of content-based image retrieval

The ranking method is a key element of Content-based Image Retrieval (CBIR) system, which can affect the final retrieval performance. In the literature, previous ranking methods based on either distance or probability do not explicitly relate to precision and recall, which are normally used to evaluate the performance of CBIR systems. In this paper, a novel ranking method based on relative density is proposed to improve the probability based approach by ranking images in the class. The proposed method can achieve optimal precision and recall. The experiments conducted on a large photographic collection show significant improvements of retrieval performance.
