This article analyzes the governance of fiscal policy in the United Kingdom and Canada under the Blair Government and the Chrétien Government. It seeks to identify whether the capacity of the core executive to steer fiscal policy has been “hollowed out.” The conclusion drawn is that in both the United Kingdom and Canada, far from having been hollowed out, there has actually been a strengthening of the capacity of the Treasury and the Department of Finance, respectively, to steer fiscal policy.  相似文献

Postmortem computed tomography (PMCT) is a relatively recent advancement in forensic pathology practice that has been increasingly used as an ancillary investigation and screening tool. One area of clinical CT imaging that has garnered a lot of research interest recently is the area of “artificial intelligence” (AI), such as in screening and computer-assisted diagnostics. This feasibility study investigated the application of convolutional neural network, a form of deep learning AI, to PMCT head imaging in differentiating fatal head injury from controls. PMCT images of a transverse section of the head at the level of the frontal sinus from 25 cases of fatal head injury were combined with 25 nonhead-injury controls and divided into training and testing datasets. A convolutional neural network was constructed using Keras and was trained against the training data before being assessed against the testing dataset. The results of this study demonstrated an accuracy of between 70% and 92.5%, with difficulties in recognizing subarachnoid hemorrhage and in distinguishing congested vessels and prominent falx from head injury. These results are promising for potential applications as a screening tool or in computer-assisted diagnostics in the future.  相似文献

This study examines the links between sexual identity and participation in political protests. Among a sample of college students (N?=?2175), we determined that sexual minority students were three times more likely to join a protest than heterosexual students. “Political distinctiveness” theories are used to explain this sexual identity gap in protesting. Following a series of path analyses, we conclude that marital status, exposure to discrimination (as a victim or observer), connections to LGB communities, participation in political groups, and liberal identities mediate the sexuality difference in protesting. Conversely, measures of educational attainment, exposure to multicultural classes, and internalized homophobia were not mediators.

Research on sexual and gender minority student achievement indicates that such students report lowered achievement relative to other students. Increased victimization and less school belonging, amongst other factors, have been identified as contributing to these inequalities. However, supportive schooling structures and caregiver support may support their achievement. A nationally representative survey of secondary school students was used to identify specific factors that support achievement for sexual minority (n?=?485), gender minority (n?=?298), and heterosexual cisgender (where one’s sex assigned at birth “matches” a binary gender identity, i.e., a male assigned at birth identifies as a boy/man, n?=?7064) students in New Zealand. While reported victimization did not affect achievement for sexual and gender minority students, school belonging, and teacher expectations of success, emerged as significant factors. Differences emerged between sexual minority and gender minority achievement factors, suggesting a range of detailed policy implications and recommendations.

This article reflects on the merits and shortfalls of bilateral research programmes aimed at strengthening climate change research capabilities, using the experience from two programmes, the PACC and IHCAP in Peru and India, respectively. The study highlights key aspects of these types of bilateral programmes, namely: capacity; performance, salary and appreciation; funding; bureaucracy and hierarchy; publishing; and data sharing. Furthermore, it emerged that these programmes would benefit from a more extensive consolidation phase of the research activities and partnership rather than rapidly transferring into out- and up-scaling phases.  相似文献

Twenty years ago the publication of “Pathologies of rational choice” by Donald Green and Ian Shapiro (1994) stimulated a large debate about the usefulness of rational choice approaches in political science. While the publication of this book has fruitfully led rational choice scholars to be more attentive to links between theoretical models and their empirical implications, some misunderstandings about the theoretical contributions of this approach still affect the discipline. Based on a brief summary about the debate I show the directions in which the rational choice literature has evolved and discuss some recent significant contributions.  相似文献

The International Cricket Council and civil prosecutions of three Pakistani cricketers and their fixer brought player corruption in cricket to public scrutiny once more. A range of English media commentators and the sentencing judge referred to cricket’s loss of innocence because of the deception of the Pakistani cricketers. However, commercialisation, racism and dealings with corrupt political regimes have all exposed cricket as less innocent than many of its English defenders would admit. Furthermore, the demonisation of Pakistani cricketers as cheats blurs the boundary between individual responsibility and cultural characteristics with negative consequences for Muslims in the post-9/11 world.  相似文献

The Sino-Japanese relations have again reached to the lowest point since Koizumi’s rule. Contrary to the conventional literatures which explaining the dynamic relation from the international dimensions, this special issue highlights the different domestic actors in Japanese politics who contribute significantly to the foreign policy-making process, notably regarding Japan’s Chinese policies. While there is a significant rightward shift in domestic politics and a growing discrepancy between central and local level politicians, the quest for discursive power between the opposing camps in the relevant areas will heavily determine future Sino-Japanese relationships.  相似文献
