The 1.2 mm Electric Coring Tool (e-Core™) was developed to increase the throughput of FTA sample collection cards used during forensic workflows and is similar to a 1.2 mm Harris manual micro-punch for sampling dried blood spots. Direct short tandem repeat (STR) DNA profiling was used to compare samples taken by the e-Core tool with those taken by the manual micro-punch. The performance of the e-Core device was evaluated using a commercially available PowerPlex™ 18D STR System. In addition, an analysis was performed that investigated the potential carryover of DNA via the e-Core punch from one FTA disc to another. This contamination study was carried out using Applied Biosystems AmpflSTR™ Identifiler™ Direct PCR Amplification kits. The e-Core instrument does not contaminate FTA discs when a cleaning punch is used following excision of discs containing samples and generates STR profiles that are comparable to those generated by the manual micro-punch.  相似文献

This study examines the association between schools and student bullying behaviors and victimization among a nationally representative sample (N = 9,107) of New Zealand high school students. In particular, the study sought to explore the role of characteristics of schools and school culture with respect to bystander behavior, while controlling for individual student factors related to victimization and bullying behaviors. Results indicated that a total of 6% of students report being bullied weekly or more often and 5% of students reported bullying other students at least weekly. Results of multilevel analyses suggested that schools characterized by students taking action to stop bullying were associated with less victimization and less reported bullying among students. In contrast, in schools where students reported teachers take action to stop bullying, there was no decline in victimization or bullying. Overall, these findings support whole-school approaches that aid students to take action to stop bullying.  相似文献

This paper introduces the concept of “tonal gravity” through a multimodal analysis of a YouTube video to demonstrate how multimodality is key to the construction of “Rule Britannia” as a sectarian song. The analysis focuses upon the multimodal semiotics of social distance which has been a key concept in sociological and anthropological traditions in recent times. This concept offers a means to understand the social semiotic relationship between Self and Other in multimodal discourse. Following previous work in social semiotics and music studies which examine how visual composition, music and the voice have constructed social distance or expressions of intimacy, I introduce the concept of tonal gravity which extends the metaphors of semiotic space in previous work in the musical mode, to account for a fuller understanding of how music helps narrate the multimodal Self and Other. This is introduced via a close multimodal analysis of “Rule Britannia” as a Rangers Football fan video which is only transformed into a sectarian text through multimodal collocation where different semiotic resources in various modes act in combination to produce a dominant Self actively prejudiced against a low Other.  相似文献

The United States (US) launch infrastructure is at a crisis point. Human access to space embodied in the Space Shuttle is due to be phased out by 2010. Currently, there are no heavy lift, 100 ton class launchers to support the US national vision for space exploration. Medium and large expendable launch providers, Boeing's Delta IV, and Lockheed-Martin's Atlas V Evolved Expendable Launch Vehicles are so expensive that the Delta no longer carries commercial payloads and the Atlas is unlikely to show significant growth without equally significant cost reductions and commercial traffic growth. This set of circumstances questions US dependence on these launch vehicles for national security purposes. High cost growth also exists with small launch vehicles, such as Pegasus, and the promising new field of small and microsatellites is little developed in the US, while foreign efforts, particularly European, are expanding largely on the availability of low-cost Russian boosters. One bright point is the emerging private sector, which is initially pursuing suborbital or small lift capabilities. Although such vehicles support very limited US Department of Defense or National Aeronautics and Space Administration spaceflight needs, they do offer potential technology demonstration stepping stones to more capable systems needed in the future of both agencies. This article outlines the issues and potential options for the US Government to address these serious shortcomings.  相似文献

The World Bank's recent concern for ‘empowerment’ grows out of longer standing discussions of participation, non-governmental organisations (NGOs) and civil society. While commitments to empowerment enter World Bank texts with relative ease, their practice within Bank-funded projects is far more contingent, and the meanings they assume become much more diverse. This paper considers the relationship between such texts and the development practices which emerge, using an analysis of the ‘organisational cultures’ of the Bank and the many organisations on which it depends in the implementation of its rural development programmes. The paper presents a framework for analysing these organisational cultures in terms of (a) the broader contexts in which organisations and their staff are embedded; (b) the everyday practices within organisations; (c) the power relations within and among organisations; and (d) the meanings that come to dominate organisational practice. A case study of a development programme in Bangladesh is used to illustrate the ways in which cultural interactions between a variety of organisations – the World Bank, government agencies, NGOs, organisations of the poor, social enterprises – mediate the ways in which textual commitments to empowerment are translated into a range of diverse practices.  相似文献

I hope that I will not be regarded as demeaning either myself or my fellow contributors to these papers in honor of Chester Barnard if I suggest that the most valuable product of this exercise may be to cause some readers who have never done so to read The Functions of the Executive, and some others who have done so in the distant past, to read it again.(1) Barnard's book is often referred to as "hard," both in the senses of hard to read and rigorous; no one is likely to recommend if for bedtime or ocean beach reading. But I believe that its "hardness" is closely related to the depth and rigor of its ideas, and that it is written about as clearly and simply as the nature of these ideas will admit. Barnard does not use long words where short words will do, nor many words where few will do. For anyone who devotes thought to organizations, its messages are pretty clear, and refreshingly creative. When read attentively, it can be read with enjoyment.  相似文献

Abstract

In this article, the authors trace how the Anglo-Australian system of criminal law constructs crime within the family differently from other forms of crime. The zone of legal impunity for intrafamilial crime was carved out by special defences and immunities, such as provocation and marital rape, as well as policing policies and practices that effectively decriminalised “domestic” forms of physical and sexual abuse. Legal impunity was never absolute, and there were notable exceptions where the familial and gendered aspects of the crime in fact aggravated the offence, such as the law's treatment of spousal murder by females as a form of “petty treason”, warranting the most severe punishment of burning at the stake. Reforms in the late twentieth century removed overt forms of gender discrimination from the criminal law, exposing a new legal visibility of crime within “the family”, though as the authors conclude, there are still remnants of differential treatment in fields of sentencing law and practice.  相似文献

China’s emergence as an economic and military power has given rise to apprehensions globally, related not only to China’s cultural and historical ‘alienness’, but also to its apparent willingness to challenge the global system and architecture of global governance. While non-Western countries are wary of the possible impact on them and on the global order of Chinese actions, they appear to be willing to cooperate with China on some global issues in order to change a system often seen as inequitable and unbalanced. Yet, the West seems to conflate the idea of a rising China with that of other emerging markets. Given their historical, political and cultural experiences, however, their access to power and influence, if and when it happens, need not necessarily take the same route as China. This is true particularly of India; India is likely, at least for the foreseeable future, to remain within the existing paradigm of global governance, though it may seek to adapt the rules and structures to better reflect its economic, political and security interests. This would not preclude cooperation on a selective basis on specific global issues with different partners, particularly in the realm of global challenges such as climate change, non-proliferation, international trade and finance and the global commons, such as space, the oceans and cyberspace.  相似文献

In this article, we combine a game‐theoretic treatment of public goods provision in networks with a statistical network analysis to show that fragmented opposition network structures lead to an increase in conflictual actions. Current literature concentrates on the dyadic relationship between the government and potential challengers. We shift the focus toward exploring how network structures affect the strategic behavior of political actors. We derive and examine testable hypotheses and use latent space analysis to infer actors’ positions vis‐à‐vis each other in the network. Network structure is examined and used to test our hypotheses with data on conflicts in Thailand from 2001 to 2010. We show the influential role of network structure in generating conflictual behavior.  相似文献

The article argues that the study of western democracies benefits from a conceptualisation of Christian churches as societal veto players characterised by three features: their power, which depends on their potential for mobilisation; their preferences, which can be deduced from churches' official statements and which are often outside the political spectrum; and their coherence, which determines the size of their indifference curve. Conceptualised as societal veto players, churches can be included in actor-centred theories of policy-making. Particular attention should be paid to veto points, church–state relations and religious parties, as these are the features of the political system that affect churches' behaviours. A comparative study of churches' roles in stem-cell policies illustrates the use of the concept. The study shows that the Catholic Church is a ‘stronger’ veto player than protestant churches, but that this stronger role can have paradoxical effects on the resulting policies and the policy process.  相似文献
