The article uncovers evidence that the end of the Cold War has provideda dividend in terms of reduced transnational terrorism. Significant short-run and long-run effects are quantified with time-series analysis to be concentrated in reduced bombings and hostage-taking incidents. Presumably, this dividend is the result of less state-sponsorship of terrorism by the Commonwealth of Independent States and other states, as well as the result of measures taken by industrial states to thwart terrorist attacks. A dividend does not appear untilthe last three quarters of 1994, at which time moves were well under way to integrate Eastern Europe with the West. Moreover, prior to this period, significant efforts had been made among Western nations to augment cooperative efforts to curb terrorism and to bring terrorists to justice. Using data for 1970 through mid-1996, we also examine trends and cycles in terrorist modes ofattack. There is virtually no evidence of an upward trend in transnational terrorism, contrary to media characterizations. All types of terrorist incidents display cycles whose duration lengthens with logistical complexity. Any change in these cycles in the post–Cold War era is concentrated in the high-frequency or short-lived cycles. 相似文献

Characteristics prevalent in known child abusers and in child victims of abuse (i.e., internalizing, externalizing, sociopathy, delinquency, and nonrational conflict-solving tactics) were examined as predictors of abuse potential in adolescents. The Child Abuse Potential (CAP) Inventory (Milner, 1986) was administered to male (n = 71) and female (n = 63) teenagers attending alternative educational sites due to behavioral problems or pregnancy. Regression analyses found unique variance in abuse potential contributed by youth (16%) and teacher (6%) reports of internalizing behavior, and youth reports of sociopathy (4%) and delinquency (4%) for a total of 33% of the variance (p < .0001, n = 91) after controlling for age, sex, and pregnancy status. Number of elevated predictors in each student was also related to increased abuse potential (r = .39, p < .001). Pregnancy status and SES were not independently associated with abuse potential. Conduct disorder as a probable precursor to future abusive behavior is suggested, and the use of the CAP with adolescents is discussed. 相似文献

The Role of Interface on the Impact Characteristics and Cranial Fracture Patterns Using the Immature Porcine Head Model 下载免费PDF全文

The role of impact interface characteristics on the biomechanics and patterns of cranial fracture has not been investigated in detail, and especially for the pediatric head. In this study, infant porcine skulls aged 2–19 days were dropped with an energy to cause fracturing onto four surfaces varying in stiffness from a rigid plate to one covered with plush carpeting. Results showed that heads dropped onto the rigid surface produced more extensive cranial fracturing than onto carpeted surfaces. Contact forces generated at fracture initiation and the overall maximum contact forces were generally lower for the rigid than carpeted impacts. While the degree of cranial fracturing from impacts onto the heavy carpeted surface was comparable to that of lower‐energy rigid surface impacts, there were fewer diastatic fractures. This suggests that characteristics of the cranial fracture patterns may be used to differentiate energy level from impact interface in pediatric forensic cases. 相似文献

Donor’s demand equations for alternative forms of aid are derived for three allocation processes: noncooperative Nash-Cournot,
cooperative Lindahl, and bureaucratic. Based on OECD data for official development assistance for 1970–2001, we apply non-nested
tests to distinguish between Nash-Cournot and Lindahl reduced-form equations for 15 major donor nations. Noncooperative Nash-Cournot
behavior characterizes many donors, with a few abiding by bureaucratic behavior and none by Lindahl behavior. Joint products
are present for multilateral and bilateral giving. Despite the common-pool nature of giving to multilateral organizations,
countries derive donor-specific benefits and often view others’ donations as complementary to their own gifts.

The emerging field of synthetic biology (SB) is just entering policy debates. Reports from non-governmental organizations, such as the ETC Group and the International Risk Governance Council, have recently been issued, but there have been few systematic analyses of the policy problems that we will likely face as this area develops. Biosecurity issues are the most defined; other societal oversight issues and implications have not been well explored. Although SB could assist in addressing pressing global challenges, such as sustainable and renewable energy, there are considerable societal concerns that accompany its development and applications. This article is designed to anticipate and prepare for these concerns by identifying policy problems associated with SB oversight, upstream of its development. Projected applications of SB are reviewed and a typology of them is developed. Key oversight policy problems are then identified based on historical experiences with other emerging technologies, such as nanotechnology and biotechnology. Problems associated with biosecurity, biosafety, intellectual property, and ethics are discussed in relation to the typology of SB applications to identify applications of the highest potential concern. Finally, policy options for SB oversight are considered, preventative to promotional. We propose that different categories of SB application may warrant different oversight regimes: there might not be an appropriate “one size fits all” approach. We stop short of making specific recommendations, but suggest that the typology, problems, and oversight options identified in this article be used as a starting point for deliberative, democratic decisionmaking processes that take into account a wide range of perspectives about risk, economic impact, scientific progress, and moral reasoning in the design of oversight systems. 相似文献

Abstract Measuring motivation to change in offender populations is important both for selection into treatment programmes and for assessing progress in therapy. Two studies are reported in this paper, both looking at the psychometric properties of questionnaires designed to measure stage of change in therapy. The samples used were patients detained in special hospitals under the Mental Health Act (1983) classification of psychopathic disorder. The first study provides norms for this group on the stages of change in psychotherapy questionnaire, plus some additional information on its relationship with self-esteem and self-efficacy measures. The second study looked at a brief version of the stages of change questionnaire, concluding that its psychometric properties were such that further use was contra-indicated. 相似文献
