The concept of a regime complex has proved fruitful to a burgeoning literature in international relations, but it has also opened up new questions about how and why they develop over time. This article describes the history of the energy regime complex as it has changed over the past 40 years, and interprets this history in light of an interpretive framework of the sources of institutional change. One of its principal contributions is to highlight what Stephen Krasner referred to as a pattern of “punctuated equilibrium” reflecting both periods of stasis and periods of innovation, as opposed to a gradual process of change. We show that the timing of innovation depends on dissatisfaction and shocks and that the nature of innovation—that is, whether it is path-dependent or de novo—depends on interest homogeneity among major actors. This paper is the first to demonstrate the empirical applicability of the punctuated equilibrium concept to international regime complexes, and contributes to the eventual development of a dynamic theory of change in regime complexes.  相似文献

PurposeIn many European countries, initiatives have emerged to reduce the use of seclusion and restraint in psychiatric institutions. To study the effects of these initiatives at a national and international level, consensus on definitions of coercive measures, assessment methods and calculation procedures of these coercive measures are required. The aim of this article is to identify problems in defining and recording coercive measures. The study contributes to the development of consistent comparable measurements definitions and provides recommendations for meaningful data-analyses illustrating the relevance of the proposed framework.MethodsRelevant literature was reviewed to identify various definitions and calculation modalities used to measure coercive measures in psychiatric inpatient care. Figures on the coercive measures and epidemiological ratios were calculated in a standardized way. To illustrate how research in clinical practice on coercive measures can be conducted, data from a large multicenter study on seclusion patterns in the Netherlands were used.ResultsTwelve Dutch mental health institutes serving a population of 6.57 million inhabitants provided their comprehensive coercion measure data sets. In total 37 hospitals and 227 wards containing 6812 beds were included in the study. Overall seclusion and restraint data in a sample of 31,594 admissions in 20,934 patients were analyzed. Considerable variation in ward and patient characteristics was identified in this study. The chance to be exposed to seclusion per capita inhabitants of the institute's catchment areas varied between 0.31 and 1.6 per 100.000. Between mental health institutions, the duration in seclusion hours per 1000 inpatient hours varied from less than 1 up to 18 h. The number of seclusion incidents per 1000 admissions varied between 79 up to 745. The mean duration of seclusion incidents of nearly 184 h may be seen as high in an international perspective.ConclusionCoercive measures can be reliably assessed in a standardized and comparable way under the condition of using clear joint definitions. Methodological consensus between researchers and mental health professionals on these definitions is necessary to allow comparisons of seclusion and restraint rates. The study contributes to the development of international standards on gathering coercion related data and the consistent calculation of relevant outcome parameters.  相似文献

The present study empirically investigates whether personality disorders and psychopathic traits in criminal suspects are reasons for diminished criminal responsibility or enforced treatment in high security hospitals. Recently, the tenability of the claim that individuals with personality disorders and psychopathy can be held fully responsible for crimes has been questioned on theoretical bases. According to some interpretations, these disorders are due to cognitive, biological and developmental deficits that diminish the individual's accountability.The current article presents two studies among suspects of serious crimes under forensic evaluation in a Dutch forensic psychiatric observation clinic. The first study examined how experts weigh personality disorders in their conclusions as far as the degree of criminal responsibility and the need for enforced forensic psychiatric treatment are concerned (n = 843). The second study investigated associations between PCL-R scores and experts' responsibility and treatment advisements (n = 108).The results suggest that in Dutch forensic practice, the presence of a personality disorder decreased responsibility and led to an advice for enforced forensic treatment. Experts also take characteristics of psychopathy concerning impulsivity and (ir)responsibility into consideration when judging criminal accountability. Furthermore, they deem affective deficiencies sufficiently important to indicate suspects' threat to society or dangerousness and warrant a need for forensic treatment.  相似文献

We question results claiming to extend non-cooperative models of legislative bargaining to the theoretically general and substantively typical case with an arbitrary number of disciplined parties. We identify problems with both the derivation of formal results and empirical evaluation of these. No empirically robust formateur advantage is observed in field data on bargaining over government formation. Given this theoretical and empirical impasse, we reconsider the substantive premises that should form the foundation for any new attempt to model this fundamental political process, arguing that models should be grounded in binding constitutional constraints on the government formation process in parliamentary democracies.  相似文献

In this article we analyse the news coverage of the 2009 EP elections in all 27 EU member states (N = 52,009). We propose that the extent to which these second-order elections are salient to the media depends on political parties contesting the elections. Consistent with expectations, the findings suggest that the saliency of EP elections is increasing and that the degree of political contestation over Europe contributes to this development in a non-linear fashion so that only when contestation develops beyond a certain point, does media coverage increase.  相似文献

Streptobacillus moniliformis is the primary cause of rat bite fever in North America. Children under 12 years of age are primarily infected, presenting with an acute syndrome of fever, rash, and polyarthritis. Common vectors include rats and mice. Transmission is predominantly from a bite or scratch, but contact with or ingestion of food contaminated with feces or saliva has also been reported. We report a fatal case of S. moniliformis infection in a 14-month-old-boy. At home, the child was exposed to filthy living conditions and the family had pet ferrets. Autopsy revealed a red-pink, mostly confluent rash and a circumscribed area suspicious for a possible bite mark. Cerebrospinal fluid cultures were positive for S. moniliformis. This case highlighted key features, such as the morbiliform rash, but lacked lymphadenopathy or joint manifestations. It is important to consider rat or rodent exposure as a source of infection.  相似文献

This essay introduces a special issue on the history of kāma?āstra in medieval India. It briefly reviews the secondary scholarship on the subject from the publication of the first translations of the genre at the end of the nineteenth century. It highlights the relatively unexplored history of later kāma?āstra, and stresses the need for contexualized and detailed studies of the many kāma?āstra treatises produced in the second millennium CE. The introduction, and the essays that follow, also argue for an expanded interpretive framework for the genre, moving beyond ‘sex’ and ‘sexuality,’ to a more widely defined notion of a ‘kāma world’, in which sensual pleasure is understood as being deeply enmeshed with aesthetic, ethical and cosmopolitan cultures.  相似文献
