Commission of nonsexual crimes generally antedates officially recorded sexual offenses. In particular, burglary has been hypothesized to be a potential ‘stepping stone’ in the development of one's sexual criminal career in the same way that marijuana has often been considered a ‘gateway drug’ to more serious drug-related offenses. The present study examined the officially recorded criminal histories of 828 male sex offenders to determine the relevance of burglary in their criminal histories. One third of the men in the sample (n=281, 34%) had been charged at least once for burglary. These 281 men committed a total of 762 separate incidents of burglary. Offenders with at least one officially recorded charge for burglary (BSOs) were compared with those with no such charges (SOs). Next, the characteristics of each burglary were examined and four distinct types of burglary were identified: nonsexual, covertly sexual, overtly sexual, and combination burglary/rape. BSOs accrued twice as many charges as the SOs and were significantly more likely to have an earlier age of onset, a longer criminal career, more employment problems, elementary school problems, antisocial behavior, and substance abuse.  相似文献

This article explores the utility of responsive space in the context of the strategies of Sun Tzu, Mahan, Corbett and John Boyd. Responsive launch is important to applying military strategy to space for achieving space control and in protecting the space systems which are part of the United States's critical infrastructure. It follows that if responsive launch is important in achieving military strategic objectives and protecting the national critical infrastructure, implementing responsive launch must also drive changes in satellite design and operational concepts. The article discusses some of these possible changes resulting from the implementation of a doctrine of responsive launch.  相似文献

The stability of two benzisoxazole antipsychotics was determined in vitro in decomposing porcine blood inoculated with bacteria, utilizing a high‐performance liquid chromatography with ultraviolet and fluorescence detection method for drug quantitation. Stability experiments for risperidone and paliperidone were conducted at 7, 20 and 37°C for 4 days using sterile and bacterially inoculated porcine blood. The drugs were stable in sterile blood at each temperature and in inoculated blood at 7°C, but degraded significantly in inoculated blood at 20 and 37°C. Complete loss occurred within 2 days when incubated at 37°C. The benzisoxazole‐cleaved degradation products for both drugs were identified as 2‐hydroxybenzoyl‐risperidone and 2‐hydroxybenzoyl‐paliperidone utilizing liquid chromatography quadrupole‐time‐of‐flight mass spectrometry and accurate mass measurements. The degradation products have been found in postmortem case studies, including one case where risperidone and paliperidone were not detected, indicating complete conversion can occur in situ.  相似文献

Purpose

The current study seeks to examine the relationship between low self-control and cigarette smoking, alcohol use, and marijuana use in adolescence and adulthood using behavioral genetic methodology.

Methods

Using a subsample of twin pairs from the National Longitudinal Study of Adolescent Health (Add Health), the current study estimates the genetic and environmental overlap between low self-control and substance use (or problems associated with substance use) across four waves of data collection.

Results

The overall pattern of results suggests that genetic factors explain a moderate proportion of the variance in low self-control and substance use in both adolescence and adulthood. Furthermore, bivariate genetic analyses reveal that the correlation between low self-control and substance use is due, for the most part, to common genetic and nonshared environmental factors.

Conclusions

The current study adds to a growing body of biosocial research on self-control and its relationship to criminal and analogous behaviors. The implications of our findings for the general theory of crime are discussed.  相似文献

The Treaty of Lisbon introduces an early warning mechanism (EWM) which empowers national parliaments to intervene directly at the EU level; they may now raise objections to – and even play a role in blocking – EU legislation. The EWM represents a new model of parliamentary involvement in international relations: national parliaments now constitute a virtual third chamber for the EU. Though they do not meet together in the same physical space, national parliaments collectively form a body that can, at least to some degree, perform three key parliamentary functions – legislation, representation, and deliberation. First, it gives national parliaments the power to influence legislative outcomes at the EU level. Second, it provides a new channel of representation linking the citizen with the EU. Third, it creates a new forum for debating the substantive merits of proposed EU legislation, particularly regarding its compliance with the principle of subsidiarity.  相似文献

The Russian attitude towards the European Neighbourhood Policy constitutes a serious obstacle to the realisation of the Union's agenda in its neighbourhood. The Russian challenge takes three main forms: 1) with Russia not a part of the EU's overall approach involving the principle of conditionality, the Union's legitimacy and international actorness in general is in danger of being undermined; 2) Russia is increasingly starting to put forward its own model of operation, thus hampering the realisation of the Union's goals in the neighbourhood; 3) Russia is engaging in business activities that are in effect undoing the ENP's energy component. There are no easy fixes to these problems. What the Union must do is believe in its own values and visions: it is only by example that it can promote its ideals outside its institutional boundaries.  相似文献

This article considers the ministerial career of Douglas Hogg, first Viscount Hailsham, during the 1930s and, in particular, his attitude towards the appeasement of Germany. Although Hailsham was a leading Conservative in the inter-war period and held key posts during the 1930s, his role in Britain's policy of appeasement has been overlooked. He was consistently wary of the Nazi menace and as Secretary of State for War from 1931–1935 he urged a firm line towards Hitler's Germany. As the decade progressed, however, the inescapable realities of Britain's international predicament drove Hailsham to support the government's appeasement policy, at least until September 1938. Although he forecast the near inevitability of the Second World War, he could not devise a viable alternative to the appeasement of Germany. Hailsham's experience thus offers a significant addition to the historiography of appeasement and to understanding the distinctions between “appeasers” and “anti-appeasers.”  相似文献

In the 56 years of multinational oil corporations’ operations in Nigeria, issues relating to corporate responsibility and accountability have posed a great challenge in institutionalising robust environmental management standards, and getting the MNCs to account. In spite of the developments in the area of environmental management and law, victims of environmental degradation traceable to and associated with oil and gas activities in the Niger-Delta face a great many uncertainties in their quest for justice. This article examines the issues relating to corporate accountability in the Nigerian oil and gas sector, and the components of the uncertainties sustaining them.  相似文献

This article undertakes a detailed examination of the practical desirability and legal validity of arbitration clauses under the Nigerian legal regime. This involves navigating through provisions of the relevant Rent Control and Recovery of Premises Law. Areas of incompatibility (including those bordering on jurisdiction, penal provisions and enforcement of awards) between the latter law and arbitration clauses are then discussed. Finally, recommendations are made to the effect that the Rent Control and Recovery of Premises Law should be amended.  相似文献
