This paper uses an analytical framework derived from Pierre Bourdieu's sociology to explain the genesis of the European Security and Defense Policy (ESDP). Long-term social and institutional processes at work in the making of ESDP are addressed through an emphasis on the institutionalization of social fields, the impact of structural crises, and the socialization of policy makers into specific schemes of perception and action (habitus). Two arguments follow from this framework. First, the paper shows that the creation of ESDP after 1998 would have been impossible without the prior institutionalization of two transgovernmental arenas: (1) the European foreign policy field, wherein EU diplomats vie for influence over EU policies; and (2) the international defense field, centered upon military relations within NATO. Second, ESDP results from the strategies of a number of diplomats and military leaders who, following the end of the Cold War, perceived that they faced important organizational crises in their respective fields. This sociological framework provides a more nuanced account of ESDP's creation than that proposed by the two dominant explanations in international relations theory—realism's balancing and constructivism's strategic culture convergence. Combining structural and ideational factors, it elucidates three empirical puzzles: the lack of opposition to ESDP when it was launched, the motives of policy makers who proposed ESDP, and the disappearance of alternative options for the European security architecture.  相似文献

Abstract

The NRF and the EU BG were launched to enable NATO and the EU respectively to shed some of their Cold War roles and begin to incorporate new organisational functions as means to meet their members’ needs in a changing global security environment. However, since their launch the two rapid reaction forces have both failed to fully consolidate. Our argument is that an examination of intra-NATO/EU contested identities at three levels (supra-state, state and sub-state) provides us with additional insights for the lack of success in consolidating the two sets of rapid reaction forces.  相似文献

The history of the International Conference on Penal Abolition (ICOPA) is explored, assessing major trends shaping the current growth of carceral practices and offering suggestions for the future of the conference movement. The goal here is to facilitate the expansion of abolitionism by describing the changing nature of what is to be abolished. A discussion of the emergence of prison abolitionism and of the ICOPA is presented, describing the shift in focus from prison to penal abolition. Taking these developments and character into account, an abolitionist gaze must be expanded to reflect a carceral abolition project, encompassing contemporary penal abolitionism while acknowledging the proliferation of carceral practices and spaces outside the traditional penal system.  相似文献

The quality and the quantity of information recalled by eyewitnesses during a criminal investigation is of crucial importance. To increase the volume of details recalled during an interview, the cognitive interview recommends using various retrieval strategies to enhance recall. We tested a new retrieval instruction, the open depth (OD) instruction. The efficacy of this new instruction was assessed with the number of unit of information and the accuracy rate. We also assessed the cost-and-benefit of this new instruction with measures of repetition. Students watched a video of a simulated robbery and participated later in face-to-face interviews. In Study 1 (N=60), the cognitive interview using the OD instruction increased recall compared to the interview using the change of perspective (CP) instruction, without affecting the accuracy rate. The redundancy rate was higher with the OD instruction than with the CP instruction. In Study 2 (N=40), the OD instruction generated more new information without affecting the accuracy rate than the interview using motivated recall (MR) instruction. The repeated information to new information ratio was lower with the OD instruction than with the MR instruction. The advantages of the OD instruction for investigative interviewing purposes are discussed.  相似文献

In 1746, Antoine Deparcieux (1703–1768) published Essai sur les probabilités de la durée de la vie humaine [An Essay on the Probabilities of the Duration of Human Life]. Deparcieux analyzed in detail empirical observations. As a mathematician and physicist, he can be considered, after Halley and Struyck, one of the founders of the estimation of longevity and all the issues surrounding that concept. The article analyzes the statistical data Deparcieux presented in his book and examines the way he dealt with them. He criticized the methods of his predecessors and showed what, according to him, were “good” data. Although he only had lists of annuitants or ecclesiastical registers at his disposal and no data from the government or state, Deparcieux constructed his calculations with careful regard to the value and quality of the figures used. He also envisaged a specific project to collect data about infant mortality. His work holds an important place in the history of French demographic statistics.  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
