While arms control and disarmament represent efforts to respond to the military and political factors in the arms race, there has not been a com- parable effort to reduce the economic incentives. To do so military contrac- tors would have to be able to convert their production facilities to civilian manufacturing without loss of profits or workers. 相似文献

We examine whether nations, faced with the threat of terrorism, will be motivated to engage in the efficient amount of retaliation against terrorists. We demonstrate that the problem confronting the efforts of nations to achieve an optimal retaliation against terrorists is understated by the traditional free-rider analysis. In particular, nations have the option of actually selling or reducing the public good of retaliation, provided through the efforts of others, by offering safe havens to terrorists in return for the terrorists' pledge to attack elsewhere. This paid-rider behavior is also shown to apply to other public good scenarios.The authors gratefully acknowledge the helpful comments of Gordon Tullock on an earlier draft.

Irish (135) and United States (123) subjects, aged from 8 to 17 years, wrote essays on their respective homelands. A content analysis revealed that American subjects, as they grow older, identify the homeland increasingly with its political ideals, while Irish subjects identify theirs with certain psychological ideals which they associate with the rural culture and landscape. Irish essays tended to be longer and more varied, and they showed a higher level of affective development. Profiles of the homeland on 7 semantic differential scales showed the break-up of a halo effect in the Irish sample. Adolescents in both countries showed a transition from concrete to abstract topics with age. The implications of these findings for research on the adolescent self-image are discussed. 相似文献

This paper presents the results of an evaluation of an early intervention, risk-reduction strategy versus a standard intervention approach in the treatment of inner-city youth at high risk of adopting a deviant lifestyle. It examines baseline and 1-year follow-up information provided by 408 youth admitted to 2 community-based Baltimore City Youth Bureaus offering counseling services for neighborhood youth referred for delinquent and other problematic behavior. In the study, one of these bureaus served as the experimental intervention clinic and the other as the control, or standard intervention, clinic. Outcome measures involved substance abuse; sexual activity; contact with juvenile authorities; and delinquent activity, including violence-related activity. Regression analyses of outcome measures revealed significant differential results for delinquent activity, which favored the experimental intervention. Relationships between risk/protective factors and outcome are discussed. 相似文献

This article examines the mode of understanding and experiences of family relationships of Chinese migrant women in Britain. In contrast to much existing research work on the patterns and experiences of postwar settlement of unskilled Chinese male labourers in Britain, the focus here is on the life stories of 41 Chinese women with different migration trajectories and varying economic and cultural capital. Their oral testimonies reveal Chinese women's diverse expectations and experiences of migrant family relationships and their different strategies to achieve self-fulfillment both within and outside the confines of the migrant family. For some women, migration brings opportunities for a fulfilling and independent lifestyle. They are successful in negotiating their way around and sometimes out of their initial familial and social position. For others, they bear the disproportionate cost and labour of familial strategies of advancement and remain vulnerable to the most constraining aspects of diasporic existence. 相似文献

A method for simultaneous enantiomeric separation of ephedrine, pseudoephedrine, and methamphetamine (MA) in a single run by simple capillary zone electrophoresis (CZE) with beta-cyclodextrin as a chiral selector is described. The effects of the buffer pH, phosphate concentration, beta-cyclodextrin concentration, voltage and temperature on the peak resolution were examined. Good enantiomeric resolution was attained for each analyte under our optimized conditions: 15 mM beta-cyclodextrin, 300 mM NaH2PO4 at pH 2.5 with an uncoated capillary (64.5 cm x 50 microm), applied potential at 20 kV and temperature at 30 degrees C. Ultraviolet (UV) detection at a fixed wavelength (200 nm) was employed using a diode array detector. Using phentermine as an internal standard, migration times for all analytes are reproducible within 0.16% for intra-day and 0.6% for inter-day runs. Application of this method to the analysis of confiscated drugs is discussed. 相似文献

Assessment of the role of air bag deployment in injury causation in a crash of any severity requires analysis of occupant, vehicle, and impact data. The potential injurious role of an air bag is independent of crash severity and is more obvious in minor collisions, particularly those involving "out-of-position" occupants. Factors such as occupant height and other constitutional and medical factors, intoxication, age, type, and proper use of other restraint systems, pre-impact braking and multiple impacts can contribute to an occupant being "out-of-position." Two injury mechanisms are described in out-of-position occupants: "punch-out" when the individual covers the air bag module before deployment and "membrane-force" when the occupant contacts a partly deployed air bag. Each mechanism is associated with injury patterns. In adults, "punch-out" can cause thoraco-abdominal trauma and "membrane-force" loading can lead to craniocervical injury. This can also occur in short-statured occupants including children subjected to both types of loading. In more severe collisions, other factors, e.g., intrusion, steering column and seatbelt loading and other occupant compartment contacts, can contribute to trauma. 相似文献

Recent research has indicated that vulnerable incarcerated young offenders--such as those at risk of suicidal behaviour, those on formal protection due to their inability to assimilate into mainstream, and those who are bullied but remain in normal circulation--display impoverished problem-solving abilities. Furthermore, deficits in their problem-solving skills are significantly correlated with levels of anxiety, depression, and hopelessness. This study evaluated the effectiveness of a time-limited, group-based problem-solving training intervention compared with a no-treatment control for vulnerable, incarcerated young offenders. A total of 46 young offenders were equally allocated to intervention or control groups. Intervention participants experienced significant reductions in their levels of anxiety, depression, and hopelessness and improvement in their self-assessed social problem-solving abilities. Gains in aspects of self-assessed problem-solving ability and mental health for the intervention group continued to be evident at 3-month follow-up. Methodological concerns in this study and directions for future research are discussed. 相似文献

In this article, the authors build on previous discussions of the possible role of shame and guilt in sexual offending. They review the general psychological literature on shame and guilt and conclude that the distinction between internal and external shame is an important one in considering sexual offenders. The effects of shame and guilt on victim empathy and relapse are discussed, and it is proposed that the phenomena of shame and guilt have implications for treatment beyond those identified in previous studies. Shame is a salient feature in the initial presentation of many sexual offenders against children. Furthermore, aspects of the treatment of sexual offenders can be characterized as a shift from shame toward guilt. Implications of shame and guilt for treatment of sexual offenders are described. 相似文献
