A series of experiments were performed to evaluate and document the effect of a TASER (“stun gun”) on triacetone triperoxide (TATP), an easily manufactured explosive used often in IEDs and suicide bombing vests. TATP samples were synthesized and subjected to several tests of their sensitivity. These samples were run through a BAM Friction test with a result of <0.5 N, Impact Test with a result of 5.8 ± 0.4 cm, and Electrostatic Discharge test with a result of 0.073 ± 0.018 J. In addition, TATP was shocked with a TASER in a variety of configurations. The TATP reacted in 17/17 tests when the TASER arced through the TATP and 0/4 times when the TATP was configured in such a way that the TATP was not subjected to the electrical arc. Based on the experimental data, TATP will readily explode in a variety of configurations by a TASER or similar device. Testing should be expanded, as the data presented here are limited to a single formulation of TATP. Just one of a large array of TASER‐like devices by a single manufacturer were tested; other devices, scenarios and formulations of TATP and other likely threat materials should be assessed. 相似文献

This study explored the extent to which transportation difficulties were associated with social, psychological, and academic experiences of urban, at-risk students who recently experienced a school transition. Participants included 165 predominantly African American and Latino/a high school youth with and without disabilities, a critical population for community psychology to address given their likelihood of multiple marginalizations. Results suggested transportation problems within school predicted more school stressors and aggressive behavior. Transportation problems to and from school predicted fewer school resources, less school belonging, and more school stressors, anxiety, and depression. Greater time to get to school predicted fewer school resources, less school belonging, and more depressive symptoms. This study demonstrates the importance of including transportation in how the school day is conceptualized, and offers several implications for how transportation services can be best addressed. 相似文献

Conflict has a carbon footprint. Crime is a subtype of conflict. Citizen on citizen predation by force or fraud, and responses
to it, have carbon costs. The paper reviews relevant literatures and notes the absence of recognition of the nexus between
crime and carbon-profligate lifestyles. The writers contend that looking at crime and disorder through a carbon costing 'lens'
would profoundly influence social and criminal justice policy. The precise quantification of the carbon costs of crime is
beyond the scope of this paper. The preliminary estimates contained herein suggest that the direct carbon costs of crime are
substantial and the consequential costs more so, to the point where it is difficult to envisage a high crime society being
a low carbon society. Recognition of this would lead to a major shift in policy favouring primary crime prevention through
the design, implementation and maintenance of products and services less prone to crime. The costs of crime, both fiscal and
carbon, would be a matter for regret rather than action were it not for the demonstrable success of schemes to design out
crime, for example from residential environments. These are briefly discussed. The scope for further improvement in designing
out crime seems considerable, and an intensive programme of research to explore avenues for advance is advocated. 相似文献

Legal scholarship is naturally inclined towards explanations and justifications of contemporary law. In the case of restrictive covenants and building schemes this has led to a distorted perception of the historical record, as revealed in recorded case reports dating from the nineteenth century. It is argued that the restrictive covenant had its historical genesis not in a response to industrialisation and mass urbanisation, but in the developments of resort towns in the eighteenth and early nineteenth centuries, as a response to the needs of land developers. Furthermore, it is argued that a better historical understanding of these origins illuminates contemporary problems concerned with the adaptability of law and the potential roles of law in development. 相似文献
