Indiana statute allows police to seize firearms without a warrant if the officer believes a person meets the law's definition of “dangerous.” Review of the use of this law in Marion County (Indianapolis), Indiana, showed that prosecutors filed petitions in court to retain weapons seized by police under this law 404 times between 2006 and 2013. Police removed weapons from people due to identification of a risk of suicide (68%) or violence (21%), or the presence of psychosis (16%). The firearm seizures occurred in the context of domestic disputes in 28% of cases and intoxication was noted in 26% of cases. There were significant demographic differences in the circumstances of firearm seizures and the firearms seized. The seized firearms were retained by the court at the initial hearing in 63% of cases; this retention was closely linked to the defendant's failure to appear at the hearing. The court dismissed 29% of cases at the initial hearing, closely linked to the defendant's presence at the hearing. In subsequent hearings of cases not dismissed, the court ordered the destruction of the firearms in 72% of cases, all when the individual did not appear in court, and dismissed 24% of the cases, all when the individual was present at the hearing. Overall, the Indiana law removed weapons from a small number of people, most of whom did not seek return of their weapons. The firearm seizure law thus functioned as a months-long cooling-off period for those who did seek the return of their guns. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

In this article, an investigator who is outside of the connectionist / dynamic systems (CD) tradition, but is sympathetic to many of its theoretical stances, considers whether these are separate approaches and what the two approaches mean for the development of information processing. It is argued that these approaches have not been defined in the target articles of this special issue narrowly enough to make them clearly separate approaches. Rather, they appear to emphasize different aspects of a common approach. It is also suggested that they do not form an overarching theory of development but do form an important theoretical approach at one level of analysis. In particular, one may sometimes, but not always, have to get into nonlinear interactions between faculties of the mind to predict and explain behavior. Finally, an attempt is made to challenge the CD approach to become more global by confronting the issue of how attention and conscious awareness should be represented in these models, and how the development of them may occur. Evidence of changes in automatic and attention-related parameters of processing may provide a scaffolding upon which better CD models can be constructed. 相似文献
