Competing spatial models of voter choiceare compared in the context ofparliamentary representatives selectedthrough single-member district, pluralityelections where party platforms areemphasized over individual candidates.Respondents of the 1987, 1992, and 1997British general election surveys ratepolitical parties on a series of issuescales. Ordered logistic regressions ofparty evaluations under proximity,directional, and mixed models reveal thatthe classic spatial model and thedirectional model perform equally well.Differences center on perceptions of thestatus quo, as voters appear to evaluatethe incumbent party (here, theConservatives) slightly differently thanminority parties (Labour and the LiberalDemocrats). The proximity model worksbetter for voter evaluations of governingparties while the directional model workswell for opposition parties. 相似文献

We examine the limits of ecological inference methods by focusing on the case of split-ticket voting. Burden and Kimball (1998) report that, by using the King estimation procedure for inferring individual-level behavior from aggregate data, they are the first to produce accurate estimates of split-ticket voting rates in congressional districts. However, a closer examination of their data reveals that a satisfactory analysis of this problem is more complex than may initially appear. We show that the estimation technique is highly suspect in general and especially unhelpful with their particular data. 相似文献

A 1H nuclear magnetic resonance (1H NMR) method for the determination of gamma-hydroxybutyric acid (GHB) and gamma-hydroxybutyrolactone (GBL) in human serum and urine using spiked samples has been developed. The method gives linear responses (correlation coefficients of 0.99 or greater) over the concentration range 0.01 mg/mL to 4.0 mg/mL in urine and 0.3 mg/mL to 2.0 mg/mL in serum. No sample pretreatment is required. Studies of the chemical interconversion of GBL and GHB showed hydrolysis of GBL to be rapid at pH 11.54, slower and less complete (30% hydrolysis) at pH 2.54 and slowest at pH 7.0, reaching 30% hydrolysis in about 40 days. No esterification of GHB was observed at any pH. 相似文献

The so-called devolution revolution was a significant themein American federalism in the 1990s. Opinions on the issue varywidely. Some suggest that "major changes" occurred in intergovernmentalrelations. Others were pessimistic about the occurrence of anydevolution during the decade. We investigated changes in intergovernmentalrelations between the national and state governments in the1990s on the basis of Elazar's approach to American federalisminvolving: (1) administration, (2) cooperation and coercion,and (3) regulation. We used American State Administrator's Project(ASAP) data collected in 1994 and 1998 to access state administrators'perceptions of national fiscal and regulatory impacts on stateagencies. We conclude that state administrators' perceptionof national fiscal and regulatory impacts changed only moderatelyfrom 1994 to 1998, and that evolution rather than revolutiondescribes better the character of state-national intergovernmentalchanges during the 1990s. 相似文献

No consensus yet exists on how to handle incidental findings (IFs) in human subjects research. Yet empirical studies document IFs in a wide range of research studies, where IFs are findings beyond the aims of the study that are of potential health or reproductive importance to the individual research participant. This paper reports recommendations of a two-year project group funded by NIH to study how to manage IFs in genetic and genomic research, as well as imaging research. We conclude that researchers have an obligation to address the possibility of discovering IFs in their protocol and communications with the IRB, and in their consent forms and communications with research participants. Researchers should establish a pathway for handling IFs and communicate that to the IRB and research participants. We recommend a pathway and categorize IFs into those that must be disclosed to research participants, those that may be disclosed, and those that should not be disclosed. 相似文献

The present article extends prior research to identify the predictors of police stress from work place problems, the resources available through social support, different strategies for coping with stress, and conditions unique to policing in South Korea. The unique conditions are perceived public perception of police and attitudes towards women working outside of the home. Seven hundred officers were asked to participate in the research, and 686 did participate (96 percent response rate). Almost half of the variance in stress could be explained. Reports of being ridiculed and “set up” in dangerous situations, and to a lesser extent, lack of support from superiors and perceived disrespect from the public, were salient predictors of stress. Coping strategies did not moderate the associations between stressors and stress. Findings were interpreted in relation to collectivist culture and possible points of intervention. 相似文献
