As long as we conceive of the fight with al Qaeda as a war, the fight will remain unwinnable and the goal of effective destruction will remain beyond our reach, according to the author. Historically speaking, modern wars require negotiated conclusions or the complete eradication of present and future threats. The former is politically impossible and the latter is historically unachievable.  相似文献

The origins of the Bureau of Justice Statistics and criminal justice statistics in general go back 150 years, but the U.S. President's Commission on Law Enforcement and Administration of Justice in 1967, along with subsequent panels and commissions, added urgency and specificity to the work to be done to improve our understanding of the operation of the criminal justice system and of crime. Criminal justice statistics have the potential to be used to shape and evaluate specific policies and programs when the statistics are timely, accurate, and relevant to the decisions being made for policy formulation or evaluation. The full development of effective criminal justice statistics on crime and the administration of the justice system can provide for informed decision making and more insightful resource allocation. In this article, I summarize the historical progressions and evolution of criminal justice statistics in light of the changes affecting the justice environment and propose future work.  相似文献

The occupational stress of police officers, and its’ effect on working memory and other psychological and behavioral factors over a two-week work period have been investigated. Cognitive performance and stress levels were examined at pre and post work cycles by using a memory test and several self-reporting surveys, each designed for a specific purpose and to gauge a particular set of behaviors and personality traits. The police officers were assigned to patrol duties at the time of the investigation and placed into three groups based on years of service (1–20 years). The results of the investigation identified a deficit in working memory in Junior, Veteran, and Senior Officers, based on the Ray Osterreith Complex Figure Scores at Baseline (pre-stress) vs. Test Day (post-stress). The other survey tools measuring stress impact on personality and behavior, did not demonstrate any statistical differences in the responding groups of officers in their survey performances.  相似文献

In an era when democratization is stalled or in retreat in many parts of the world, it is important to highlight the successful democratic experience of East and Southeast Asia in recent decades. Five consolidated democracies have emerged since the mid-1980s; only Thailand has seen some backsliding with the 2006 coup. The Asian cases provide insights into several major debates in the democratization literature, including the relative importance of culture, history, economic structure, and the optimal sequencing of political and economic reform. This article reviews these issues, with particular attention to the role of outside powers in underpinning democratization. Ultimately, the Asian cases offer evidence for optimism about the prospects of a Fourth Wave of democratization.  相似文献

The degree to which the international security environment had changed after the Cold War became evident with the attacks on September 11. As a result, military forces in the United States (and perhaps in the West generally) are evolving from their Cold War and immediate post-Cold War perspectives to confront transnational and subnational non-state dangers. These changes have significant implications for military professionalism and the relations between the military and society. They are explored through a modified “Postmodern Military” model, called here the “Hybrid” model.  相似文献

High levels of non-authentic sequence data can be generated by traditional PCR-based methodologies when DNA is damaged, template numbers are small and/or the target amplification size too large. We therefore present an alternate methodology based on single primer extension (SPEX) amplification; that places no pre-defined size constraints on amplification and interacts with only one of the DNA strands at the target locus.  相似文献
