In this article we seek to trace through the major stands of British Euroscepticism and concentrate, in particular, on the importance of a powerful 'hyperglobalist' Eurosceptical strand within British Conservatism. We investigate the British Conservatives' recent divisions over European integration, against the background of the party's increasingly marginal status in British party politics. The piece also draws on findings from two recent surveys of the attitudes of British parliamentarians to European integration, carried out by the Members of Parliament Project for the Economic and Social Research Council (ESRC). We explore how Conservative divisions of opinion are related in part to particular understandings of globalisation and regionalisation and attempt to show how globalist ideology has unexpectedly re–emphasised and bolstered the traditional nationalism of the Tory party and caused an increasingly hostile attitude amongst many British Conservatives towards the European project as it is presently constituted. We also examine recent attempts to map British Conservative Euroscepticism on to continental varieties using a mixture of ideological positioning and party system (Taggart 1998), arguing that this ignores the extent to which British Eurosceptics advance unique (in EU member state terms) hyperglobalist (rather than isolationist or protectionist) arguments in objecting to further European integration.  相似文献

On 30 September 1996 the U.S. Advisory Commission on IntergovernmentalRelations (ACIR) closed its doors, ending thirty-seven yearsof advocacy for federalism and intergovernmental relations.A majority of members in the Congress felt that A CIR had becomeirrelevant to the issues facing them and agreed that littlewould be lost by terminating the commission. The Clinton administration,although supportive until near the end, withdrew its'supportout of displeasure with the commission's handling of the unfundedfederal mandates issue. The national associations representingstate and local governments were ambivalent. ACIR was no longerlooked to for solutions to the nation's intergovernmental relationsproblems. With the exit of ACIR, the federal government's lastresource for addressing broad intergovernmental issues—beyondthe confines of individual programs—is gone.  相似文献

Household survey data on age at first use of alcohol, tobacco, marijuana,and hard drugs can be biased due to sample selection and inaccuraterecall. One potential concern is attrition, whereby individuals who getinvolved with substance use at an early age become increasingly less likelyto be surveyed in successive years. A comparison of data from the NationalHousehold Survey on Drug Abuse (NHSDA) with data from a longitudinal studysuggested that attrition might have caused substantially less bias thandid forward telescoping, the inflating of age at first useover time. The evidence of forward telescoping was particularly pronouncedwith respect to age at first use of alcohol. This paper presents a procedurefor correcting the distribution of age at first use for forward telescoping(but not attrition) by viewing a portion of the NHSDA data collected insuccessive years as constituting a cohort study. Results are presented fromapplying this procedure with NHSDA data collected from 1982 to 1995 forrespondents born 1968–1973. The findings suggest that preventionprograms need to be introduced at an earlier age than would be indicatedby uncorrected retrospective data. Other implications are alsohighlighted.  相似文献

A relatively simple, routine method has been described for the qualitative identification of flurazepam and its primary metabolite 7-chloro-1-(2-hydroxyethyl)-5-(2-fluorophenyl)-1,3-dihydro-2H-1,4-benzodiazepin-2-one in urine. We have described two extractions and several identification procedures by which flurazepam and its primary urinary metabolite can be identified by TLC.  相似文献

Infectious microorganisms are important to multiple communities engaged in biodefense and biosecurity, including the agencies responsible for health, defense, law enforcement, agriculture, and drug and food safety. Many agencies have created lists of high priority infectious microorganisms to prioritize research efforts or to formally control the possession and distribution of specific organisms or toxins. However, the biological classification of infectious microorganisms is often complex and ambiguous, leading to uncertainty and confusion for scientists involved in biosecurity work. To address this problem, we created a database, known as the Microbial Rosetta Stone, which resolves many of these ambiguities and includes links to additional information on the microbes, such as gene sequence data and scientific literature. Here we discuss the efforts to coordinate organism names from pathogen lists from various governmental agencies according to biological relatedness and show the overlap of high-priority organisms from multiple agencies. To our knowledge, this is the first comprehensive coordination of pathogens, synonyms, and correct taxonomic names. The organized tables and visual aids are freely available at http://www.microbialrosettastone.com. This website provides a single location where access to information on a broad range of disease-causing organisms and toxins is available to members of the biosecurity community.  相似文献

Four reality monitoring variables were used to discriminate suspect from foil identifications in 183 actual criminal cases. Four hundred sixty-one identification attempts based on five and six-person lineups were analyzed. These identification attempts resulted in 238 suspect identifications and 68 foil identifications. Confidence, automatic processing, eliminative processing and feature use comprised the set of reality monitoring variables. Thirty-five verbal confidence phrases taken from police reports were assigned numerical values on a 10-point confidence scale. Automatic processing identifications were those that occurred “immediately” or “without hesitation.” Eliminative processing identifications occurred when witnesses compared or eliminated persons in the lineups. Confidence, automatic processing and eliminative processing were significant predictors, but feature use was not. Confidence was the most effective discriminator. In cases that involved substantial evidence extrinsic to the identification 43% of the suspect identifications were made with high confidence, whereas only 10% of the foil identifications were made with high confidence. The results of a laboratory study using the same predictors generally paralleled the archival results. Forensic implications are discussed.  相似文献
