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

This paper presents one of the first statistical analyses of the factors that determine the extent to which direct influence strategies are used by companies. New survey evidence and multivariate analysis is used to assess seven hypotheses to explain direct influence strategies. The factor of greatest significance is company size since direct influence is open only to large companies. But the extent to which direct influence is followed by large companies depends on their sector, its extent of organization, the sector's size and 'weight', and the form of the business association relevant to the sector. Direct influence is more likely where associations cover large corporate businesses (rather than owner-managers, professionals, federations or mixed associations), in sectors with a high degree of market concentration within large companies, and where their associations are relatively small. These findings are related to the logic of collective action suggesting that in sectors where there is the least chance to opt out of an association, there is a greater chance of a business also directly lobbying in order to assure itself that its interests are not being diluted and so that it can gain direct specific information or influence benefits. 相似文献

This paper focuses on the Department of Homeland Security (DHS) in order to theorise the spatialities of post-9/11 security knowledge and practice in the US. It analyses the organisational discourses that animate homeland security work, such as preparedness, vulnerability, the new threat environment, risk analysis and capabilities-based planning, and considers the implications of these practices for contemporary geographies of security. It is argued that DHS operates through a virtual ontology of threat, whereby potential, future threats are addressed as present possibilities that emerge in the spaces of everyday life. The sources of American freedoms and insecurities, the everyday, emerging circulations of goods and people, present DHS with a terrain of shifting threats from which both emergencies and preparedness may materialise. Disaster looming, the potential suspension of everyday life forms the basis for security practice as the emergency becomes a fact of life itself. The spatialities of this environment of imminent threat are considered and it is argued that the everyday emergency operates topologically as a continuous process of spatialisation. 相似文献
