Intuitively, a hand held in close proximity to a firearm at the instant of discharge will intercept a significant amount of gunshot residue, even though the hand did not actually come into contact with the weapon. There is, however, little information specifically described in the forensic science literature concerning the residue levels which might be encountered in such an instance. The present work confirms that antimony levels consistent with an individual having fired or handled a firearm may be intercepted by a hand held in close proximity. 相似文献

As a general rule, pathologies tend to impair job performance. In a study involving performance criteria and the Personality
Assessment Inventory in a sample of Louisiana police officers (N=800), OCD characteristics correlated significantly in a negative
direction with several performance criteria, such as involvement in an on-duty or off-duty at fault moving violation, number
of on-duty or off-duty at fault moving violations, any citizen complaints regarding unprofessional conduct, number of unprofessional
conduct, and accusation in any way of racially offensive conduct, behavior, verbalization, or complaints. It has been found
that the traits of obsessive-compulsive disorder, in moderation, may actually improve performance in police officers. This
agrees with the Yerkes-Dodson law, which states that peak performance occurs when a person experiences mild to moderate levels
of stress.

Human judgment and decision making has been demonstrated by several contemporary researchers to be comprised of both rational and emotive/intuitive cognitive systems; a single decision can involve both rational thinking and intuition. In the present article, a narrative approach is utilized to analyze the Susan Smith case, and this is interlaced with contemporary decision theory in an attempt to more fully understand the seemingly nonrational act (murder/attempted suicide) committed by Susan Smith in October, 1994. The ethical, legal and social implications of using an approach of this nature are discussed. 相似文献

This article examines the development of the German community in Hong Kong between the 1840s and the outbreak of the First World War. It pays particular attention to the question of how the Germans, as a minority group in the crown colony, attempted to strike a good balance between integration and segregation, cultural assimilation and dissimilation, national identity and marginalization. Through investigating their social life, missionary activities and economic activities in Hong Kong, it shows that they, on the one hand, cooperated closely with the British who were in charge of key political and economic affairs, and on the other hand worked with the local Chinese on different social stratums. Although the unification of Germany in 1870 strengthened the sense of nationhood among German people in Hong Kong, they strove to strengthen the German cultural and economic network that already existed in and around the colony, without sacrificing their business and social interests which were interwoven with those of the British and the local Chinese. It is this strategy that enabled them to survive in Hong Kong until 1914. 相似文献

It is analyzed how size differences among countries affect the benefits from climate coalitions. It is shown that size differences
lead to smaller coalitions and greater benefits than coalitions among identical countries. The importance of trigger strategies
for supporting cooperative solutions is considered. A real world example, based on the world’s six largest emitters, is used
to illustrate the implications of size differences in terms of emissions versus valuations of benefits. Climate coalitions
become smaller when ranking in terms of benefits is different from ranking in terms of emissions. Three cases of benefit valuations
are considered: benefits equal (i) share in world emissions, (ii) share in world GDP, and (iii) share of world population. 相似文献

Chinese trademark law has established the cross-category protection system of well-known trademarks based on the confusion
theory. The system, however, has many problems in practice and does not fulfill completely the needs for protecting well-known
trademarks. Consequently, when hearing trademark cases, some judges have abandoned the confusion theory instead of using the
dilution theory in judging well-known trademarks. Through analysis on 100 judgments concerning well-known trademark cases,
it can be seen that the influence of the dilution theory on the ruling of trademark cases is increasing. Certain conditions
should first be satisfied when introducing the dilution theory to rule trademark cases: Firstly, the contents of the dilution
theory shall be grasped as correctly as possible to avoid plausible understanding; secondly, the application of the dilution
theory shall adopt the existing institutional criteria as much as possible by full use of the leeway of interpretation provided
by the existing system. 相似文献
