Women are demonstrably under-represented at senior levels in Australia's international affairs. Empirical evidence shows a continuing gender imbalance in leadership positions, including in the Department of Foreign Affairs and Trade, the Department of Defence and academia. Two explanations commonly offered are that women are less motivated or lack interest in ‘hard’ international relations. These explanations are found to be unconvincing, given studies showing similar levels of ambition and interest at recruitment. Four alternative explanations are offered to account for the scarcity of female leaders in Australia's international affairs: the legacy of direct discrimination, continued indirect discrimination, inadequate support for women who balance work and family responsibilities, and socially constructed gender norms. Instead of the subject matter of international relations being too ‘hard’, or inherently masculine, it appears that it is the combined impact of these factors that has made it ‘hard’, or difficult, for women to progress to senior levels. In order to show how these barriers can be overcome, three case studies are presented of women who have achieved senior positions: Professor Emeritus Helen Hughes, Her Excellency Ms Penny Wensley and Professor Hilary Charlesworth. These examples suggest strategies that women can use to further their careers and measures that can be implemented in workplaces to improve the representation of senior women in Australia's international affairs.  相似文献

The Surgeon General's 1964 report on smoking and health, which declared that cigarette smoking was a cause of lung cancer, is considered a landmark in the history of medicine and public health. This article examines the impact of the report on medical student education by reviewing how the relationship between smoking and lung cancer was presented in medical school textbooks and syllabi between 1964 and 1987, changes in hospital smoking regulations and doctors' attitudes toward smoking following the publication of the report, and medical students' smoking patterns and attitudes toward cigarette smoking in the years after 1964. Although it provided some advanced students with additional insight into mechanisms of pathogenesis related to smoking, the education that many medical students received seems to have been neither a primary influence on their smoking patterns nor an important source of their scientific understanding of the causal link between smoking and lung cancer for at least a decade following the publication of the Surgeon General's report.  相似文献

The Dirc Mhòr gorge in the central Grampian Highlands is 1.1 km long, ~250 m wide and up to 110 m deep, and is incised in granite bedrock. It is the largest of several bedrock gorges that are incised into spurs, cols or plateau margins in the area, and its present catchment area is negligible. The floor of the gorge is covered by coarse rockfall debris, and the sides of the gorge are mantled by talus accumulations; surface water flow is absent. The gorge is inferred to have evolved over several glacial-interglacial cycles, with subglacial meltwater erosion deepening the gorge under successive ice sheets, and paraglacial rockwall collapse widening the gorge during intervening interglacial periods. Subglacial erosion may also have contributed to gorge enlargement as it widened.  相似文献

The Ecology of Games (EoG) theory couples institutional rational choice with social network theory, articulating how transaction costs, social capital, and collective action dilemmas shape networks and network outcomes in polycentric governance systems. EoG literature has often focused on social–relational ties across organizational boundaries. However, jurisdictional fragmentation and increased reliance on private contractors in local public service delivery foster another source of network connectivity—shared personnel who work for multiple service providers. Drawing upon novel data of organizational personnel from more than 500 special purpose entities responsible for delivering drinking water to local neighborhoods in the Houston metro area in the state of Texas (United States), we examine how managerial, technical, and financial service delivery personnel connect otherwise independent organizations. We find that districts regulated by a common groundwater management agency and districts which contract with one another are both more likely to share technical and managerial personnel. By studying special districts that have overlapping personnel, we broaden the scope of the EoG framework to include additional layers of governance network complexity. As individual bureaucrats and service professionals play a key role in information transfer and innovation diffusion across organizations, shared personnel networks merit consideration as a mechanism for coordination and collective problem solving in fragmented urban systems.  相似文献

Although geography has long associated itself with photography, the rapid advancement of technology has created a clear divide between the visual practices regularly used in wider society and the way photography is utilized by critical geographers in their teaching. We suggest the door is ajar for new modes of (geo)photographic thinking, and one visual tool at our disposal is social media applications that allow images to be instantly shared, analysed, and discussed. This article critically reflects on the use of Instagram to enhance student participation, engagement, and learning on a geography field course in Berlin. Based on interviews with students, their field journals, and our own critical reflections, this paper looks at some advantages of using Instagram in teaching geography, but also promotes caution and presents drawbacks to relying on instant visual digital methods.  相似文献

How and when issues are elevated onto the political agenda is a perennial question in the study of public policy. This article considers how moral panics contribute to punctuated equilibrium in public policy by drawing together broader societal anxieties or fears and thereby precipitating or accelerating changes in the dominant set of issue frames. In so doing they create opportunities for policy entrepreneurs to disrupt the existing policy consensus. In a test of this theory, we assess the factors behind the rise of crime on the policy agenda in Britain between 1960 and 2010. We adopt an integrative mixed-methods approach, drawing upon a combination of qualitative and quantitative data. This enables us to analyze the rise of crime as a policy problem, the breakdown of the political-institutional consensus on crime, the moral panic that followed the murder of the toddler James Bulger in 1993, the emergence of new issue frames around crime and social/moral decay more broadly, and how—in combination—these contributed to an escalation of political rhetoric and action on crime, led by policy entrepreneurs in the Labour and Conservative parties.  相似文献

This paper examines collaborative management groups from the perspective of policymakers seeking to increase coordination within a policy network. While governments often support collaborative groups as a tool to address perceived network failures such as a lack of coordination, the net impact groups have is unclear. I use valued exponential random graph models (ERGMs) to model relationships of varying strength among a regional network of organizations involved in 57 collaborative groups. This provides a unique opportunity to study the interplay between numerous groups and organizations within a large‐scale network. Valued ERGMs are a recently developed extension of standard ERGMs that model valued instead of binary ties; thus, this paper also makes a methodological contribution to the policy literature. Findings suggest that participation in collaborative groups does motivate coordination and cooperation amongst individual network organizations; however, this effect is strongest for: (i) organizations that are not already members of another group and (ii) organizations that do not have a preexisting tie. These results support a transaction‐cost–based perspective of how government‐sponsored collaborative groups can influence network coordination; further, they also provide an empirical example of the Ecology of Games, in which multiple collaborative institutions have interactive effects on one another within a policy network.  相似文献
