ABSTRACT

The aim of the present study was twofold. First, we wanted to quantify the level of knowledge of Swedish young people regarding sexual crime and to evaluate their supportive attitudes, while at the same time we aimed at identifying, through self-report, the sources that most contribute to such knowledge and attitudes. A sample of 245 upper secondary school students was selected from five schools in four Swedish counties. The results indicate that adolescents in Sweden have a high level of knowledge of rape, sexual molestation/harassment, and sexual exploitation of a dependent person. Furthermore, they show non-supportive attitudes to rape, sexual harassment, and sexual crime in general. However, some issues related to these types of crime proved to be confusing to the participants and, therefore, require targeting in education policies, specifically among juvenile males and those born abroad. The results are discussed in the context of the needs for sexual crime prevention.  相似文献

In recent years, scopolamine has become a drug of common use for recreational and predatory purposes and several ways of administration have been devised. A method for the rapid analysis of suspicious samples was developed, using a portable capillary electrophoresis with contactless conductivity detection. The method allows the separation of scopolamine from atropine which has a similar structure and is present along with scopolamine in some samples. The method was demonstrated to be useful for the fast analysis of several types of evidential items which have recently been reported to have been abused with fatal consequences or employed for criminal purposes. An infusion of Datura stramonium L., in which scopolamine and atropine naturally coexist, was analyzed for being frequently consumed for recreational purposes. A spiked moisturizing cream and six spiked alcoholic beverages were also analyzed. In spite of the complexity of the specimens, the sample pre-treatment methods developed were simple and fast.  相似文献

Purpose. The study extends research by Santtila et al. (2008) by investigating the effectiveness of linking cases of serial homicide using behavioural patterns of offenders, analysed through Bayesian reasoning. The study also investigates the informative value of individual behavioural variables in the linking process. Methods. Offender behaviour was coded from official documents relating to 116 solved homicide cases belonging to 19 separate series. The basis of the linkage analyses was 92 behaviours coded as present or absent in the case based on investigator observations on the crime scene. We developed a Bayesian method for linking crime cases and judged its accuracy using cross‐validation. We explored the information added by individual behavioural variables, first, by testing if the variable represented purely noise with respect to classification, and second, by excluding variables from the original model, one by one, by choosing the behaviour that had the smallest effect on classification accuracy. Results. The model achieved a classification accuracy of 83.6% whereas chance expectancy was 5.3%. In simulated scenarios of only one and two known cases in a series, the accuracy was 59.0 and 69.2%, respectively. No behavioural variable represented pure noise but the same level of accuracy was achieved by analysing a set of 15, as analysing all 92 variables. Conclusion. The study illustrates the utility of analysing individual behavioural variables through Bayesian reasoning for crime linking. Feasible applied use of the approach is illustrated by the effectiveness of analysing a small set of carefully chosen variables.  相似文献

This article looks at the position of women in the Canadian labour market and at the legislative measures adopted to address their segregation in terms of occupation, wages and working conditions. Federal and provincial legislators have, with relative success, attempted through a series of measures to respond directly to the issue of discrimination against women in the workplace and in the labour market. They have, however, remained relatively insensitive to other factors that make the situation of working women precarious, such as the rise of ‘non-standard’ work. These inequalities are not peculiar to Canada and legislative responses to these questions vary according to specific national realities and legal traditions. A study of the legislative evolution in Canada serves to illustrate some of the challenges faced to redress this gender gap.  相似文献

International literature on prison effects on recidivism tends to find little evidence of specific deterrence. If anything, imprisonment seems more likely to increase than decrease rates of offending. The present study adds to this literature by examining imprisonment and recidivism in Finland, a nation characterized by an exceptionally moderate penal culture. It has been suggested that severe sanctions need to be imposed selectively in order for them to be effective. In this research, we estimated the impact of first imprisonment on recidivism in comparison with offenders sentenced to either suspended imprisonment or community service. Using data from government population registries, we controlled for a large number of legal and extra-legal confounding factors, including criminal history and socio-demographic characteristics. We found no evidence of reduced recidivism as a result of imprisonment. Instead, consistent with prior research, we find evidence of increased recidivism in certain offender categories. We conclude with a discussion of policy implications.  相似文献

This article analyses how well Spanish political elites have responded to the issues signalled as priorities preferred by Spanish citizens from the early 1990s to the present, and to what extent the degree of correspondence between citizens' and policymakers' priorities is related to elections, type of government, issue jurisdiction and institutional friction. To measure this the authors rely on Most Important Problem surveys and several databases on laws, bills, oral questions and annual speeches, coded according to the comparative agendas project. They argue that the prioritisation of issues by political elites better matches public preferences at the agenda-setting stage than at the decision-making stage, and that correspondence of public and policymakers' priorities is inversely related to institutional friction. The evidence also illustrates that policymakers are more responsive to public priorities on those issues without shared jurisdiction, when the executive governs without a majority and immediately after elections.  相似文献

This article analyses the links between populist radical right parties and their voters regarding European integration in 11 European countries. It does so by using data from the 2008 European Social Survey and the 2006 UNC-Chapel Hill Expert Data Base on political parties and European integration. In addition to mapping the Eurosceptic orientations of political parties and their voters, the article examines the degree to which attitudes towards the EU and voting for populist radical parties are connected to each other. The results lend support to the hypothesis that most populist radical right parties have managed to establish links with their voters regarding European integration. The analysis also shows that links between populist radical right parties and their voters tend to be stronger for those parties that adopt more extreme negative positions towards European integration.  相似文献

The lack of academic interest in intelligence in France partly explains the prevalence of many preconceived ideas about French Intelligence. This article deals with the slow building of France's intelligence machinery in the nineteenth century, as part of a study of the modern French State. At this time, intelligence practices were transformed by the appearance of several intelligence bureaucracies. Studying three dimensions of the development – informal practices, formal organizations and statutory rules – the article demonstrates the closeness of intelligence to politics. Doing so it suggests that intelligence needs to be considered not only as an instrument of policy-making but as an actor at the centre of the modern French state, a part of its very essence.  相似文献

After the Tiananmen massacre of 4 June 1989 many Chinese pro-democracy activists have been able to settle in the USA. They have attempted to federate all the opposition forces overseas in an organization which aimed at influencing the US government’s policy toward China. However, plagued by factionalism, the opposition in exile has not been able to put to an efficient use the capital of sympathy that it enjoyed at the time of Tiananmen. After the failure of political organizations, Chinese dissidents have created NGOs which are regularly consulted by the Administration and the Congress. Since the mid-eighties, they represent a substantial factor in the making of American policy towards China.  相似文献
