Torso models for ballistics research require that the mechanical properties of simulant materials must match the heterogeneous nature of tissues/organs within the human thorax/abdomen. A series of energy loss experiments were conducted on fresh porcine organs/tissues at room temperature and 37°C, using steel 4.5 mm BBs fired from a Daisy® brand air rifle. They were compared to FBI and NATO specification ordnance gelatin and a candidate surrogate material called Simulant “A”. Two CED M2 chronographs measured BB velocity. The resulting energy loss was established using KE = 1/2 mv² before and after target perforation. The combined results at room temperature and 37°C were as follows: FBI specification gelatin was similar (p > 0.05) to heart and lung, spleen was similar to NATO specification gelatin, Simulant “A” was similar to hindquarter muscle, and hindquarter muscle, kidney, and spleen were similar to each other regarding energy retardation. These results can be used as a basis for the development of simulant materials to create an anatomically correct heterogeneous model. 相似文献

Convict Criminology (CC) began in the early 1990s as a reaction to the then current state of academic criminology that did not adequately reflect the voices of convicted felons. Since its beginnings, CC has attempted to draw attention to a range of problems created by the criminal justice apparatus and defenders of the status quo. Dr. Joanne Belknap’s 2014 ASC presidential address and subsequent article presented an argument that stressed the importance of activism to be considered as part of criminological research. In the process, she reviewed her career and then criticized the field of Critical Criminology, in particular Convict Criminology. The article, however, ignored the numerous efforts that CC has engaged in to build an inclusive group school, movement, organization and network that includes the diverse voices of Ph.D. educated convicts and excons, and overall reflected a superficial understanding of the history and intent of Convict Criminology. This article attempts to explain the shortcomings of Belknap’s article and clarifies misunderstandings. 相似文献

For over a century the so-called ‘Peelian’ principles have been central to the self-understanding of Anglo-American policing. But these principles are the product of modern state-building and speak only partially to the challenges of urban policing today. In fact, they stand in the way of clear thinking and better practice. In this paper, I argue that these principles ought to be radically recast and put to work in new ways. The argument proceeds as follows. First, I recover and outline the current ‘Peelian’ principles and argue that they lack the specificity, sufficiency and status required in order to do real work in the governance of policing. Second, I make the case for principles both as a regulative ideal guiding our aspirations for what policing can become and as a means of regulating police work in the here-and-now. I then develop a revised set of principles and indicate, in conclusion, how they can guide the formation of trust-producing and democracy-enhancing practices of civic policing. 相似文献

The House of Commons select committees witnessed some of the most constructive political theatre of the 2010‐2015 Parliament. Recall Rupert Murdoch's public contrition, Margaret Hodge's assault on MNC tax evasion and Keith Vaz's timely interrogations of G4S, etc. The committees also embraced social media and adopted public engagement as a key task. These developments all reflect a newly emboldened system. In recent months, four reports have been published which reflect on these developments. They also look forward to the further substantial development of committee activity. The system thus sets sail with an abundance of specific suggestions, including ideas that could have far wider and more far‐reaching democratic implications. 相似文献

Africa's proliferation of dominant-party regimes is often regarded as an obstacle to democratization. Scholars and practitioners therefore face the task of understanding how and why constitutionally legitimate challenges to dominant party rule occur. This article asks: why do some presidential succession crises act as a catalyst to dominant party fragmentation when others do not? It argues that minority factions are more likely to defect from a dominant party when they have (1) been marginalized by the majority faction and (2) confidence in their mobilizational capacity. Factional purging is in turn traced to autocratic leadership and party under-bureaucratization, whilst high levels of factional self-confidence are linked to crises of dominance and the weakness of extant opposition parties. 相似文献

Most academic research on taxation relates to higher-level issues of fiscal policy. Much public debate takes place about the calculation and incidence of different taxes, but little academic research addresses the management problems that are specific to national taxation regimes. This paper identifies emerging issues and calls for joint practitioner/academic attention on an international basis to address these issues. 相似文献
