This article examines different explanations for the cross–national diffusion of three recent innovations in bureaucratic accountability—the institution of the ombudsman, freedom of information legislation and data protection (information privacy) law. The first two explanations are based on the assumption that these innovations are by–products of modernization, either the growth of the state or democratization. The third assumes that policy is shaped through processes of international communication. A combination of methodologies is employed to conclude that while the growth of government and liberal democratic values are necessary conditions for the adoption of all three policy instruments, they are not sufficient conditions. The pattern of adoption observed is best explained by examining how evidence about these respective policies flows from adopting states to non–adopters. In the case of the ombudsman, this process can be characterized as one of lesson–drawing; for freedom of information, evidence is used for legitimation purposes; for data protection, the diffusion is attributable to harmonization through international organizations. Policy transfer is hence a multi–faceted concept that embraces a number of distinct processes of transnational learning and communication.  相似文献

Combined homicide-suicides have been classified based on the psychopathology of the perpetrator and the nature of the relationship between perpetrator and victim(s). To further understand the nature of this tragic phenomenon and to test the validity and practicality of a previously suggested classification system, investigators systematically collected data on all combined homicide-suicide events that occurred in Galveston County, Texas over a continuous 18-year period (n = 20). The most common psychopathological finding for perpetrators was high serum alcohol levels that suggested intoxication. Most combined homicide-suicides fell into one of the relational categories and most of these, as predicted, were of the consortial type, possessive subtype. As expected, due to the small sample size, the less common types of combined homicide-suicide were not represented in this sample.  相似文献

This article presents the results of new survey research that assesses the routes and activities used by UK business associations in gathering and exchanging information with European institutions. All major UK business associations are covered, ranging from trade and professional associations to associations of the self‐employed and federations. A representative sampling framework allows general conclusions for the whole association sector to be drawn. The chief findings are that there are multiple routes for European activities employed by most associations. The most important route for all categories (except federations) is the national route, using meetings with UK ministers, officials or agencies as an attempt to get them to influence the EU. The second most important route is through European associations (which is the chief route for federations), which are also seen as the most open to influence. A ‘Brussels strategy’ of direct lobbying, or a Brussels office, is the third most important route. It is the main route for 16 per cent of respondents, which is surprising given its costs but demonstrates the increasingly important light in which the European institutions are seen. The use by associations of individual member companies to lobby for them is also surprisingly high (for 10 per cent it is the main route). Association size, resources and sectoral circumstances are shown to be important influences on an association's European strategy.  相似文献

Abstract: A new screening method for detecting gamma-hydroxybutyric acid (GHB) in drink matrices, using the IonSense, Inc. (Saugus, MA) direct analysis in real time (DART) ion source coupled to a JEOL exact mass time-of-flight mass spectrometer (AccuTOF), was validated and compared with the current screening methodology. The DART ion source allows for analysis of samples under ambient conditions with little to no sample preparation. Fifty drink specimens were spiked at levels of 1, 2, 3, and 4 mg/mL GHB, and analyzed on the AccuTOF-DART. Positive detection of GHB occurred for each of the samples at each concentration level, giving 100% accuracy for the samples tested. Twenty-five of the 50 drink specimens were spiked at 1 mg/mL GHB and tested using a color test known as the GHB Color Test #3. Only two of these 25 specimens tested positive for the presence of GHB, giving only 8% accuracy. Implementation of this new methodology as a screening tool for GHB analysis will quickly eliminate negative specimens allowing the examiner to focus analysis time on those that screened positive.  相似文献
