There has been considerable debate regarding the reasons for the observed spatial variation in voting patterns at British general elections since the 1970s. Three separate models can be identified: no regional cleavage; regional economic cleavage; and autonomous regional cleavage. Analysis of data which indicated people's perceptions of their household and regional economic situations over the decade preceding the 1992 general election, together with their personal characteristics and attitudes, allows the first model to be rejected: there are clear regional differences in voting behaviour which cannot be accounted for by personal characteristics alone. Each of the other models is valid: there are clear spatial differences not only in interpretations of personal and regional prosperity, and its causes, but also in electoral responses to that; and there are significant residual regional variations when those are held constant. Approaches to the study of voting in Britain which present spatial variations as merely representations of other causes are thus rejected. 相似文献

Although paid television and radio political advertising is banned in the United Kingdom, parties fielding sufficient candidates are entitled to free air time during election campaigns for a fixed number of party election broadcasts (PEBs). Over the years, parties have experimented with a variety of different PEB formats. But the impact of PEBs on voters is underresearched. This article therefore analyzes the influence of PEB viewing in the 1997 British General Election. Though a majority do not view PEBs, those who do are influenced by them, especially in terms of their evaluations of parties and their leaders: Other things being equal, viewers of a party's PEBs become more favorably disposed to the party and its leader than those who do not see the broadcast. Labour and Conservative PEBs have no impact on vote intentions, however. But viewers of Liberal Democrat broadcasts become more likely to support that party. We speculate that this reflects different background levels of media exposure for the major parties as compared to the third party. 相似文献

We compare results of several large‐scale survey studies of whistle‐blowing by public sector employees, from samples in Australia, Norway, and the United States. Specifically, we review incidence rates of wrongdoing, whistle‐blowing and retaliation, as perceived by thousands of respondents employed by many government agencies in these countries. Despite differences in measurement in the studies and variation in results, findings suggest that wrongdoing was quite frequently observed and was reported in many cases. Retaliation resulted for far fewer than half of the whistle‐blowers, in all three nations. We also compare findings from the various studies concerning variables that predicted retaliation against whistle‐blowers in the different samples. Differences in results across the three countries add to existing evidence that country and workplace cultures can affect the whistle‐blowing process. 相似文献

This introduction reviews the contributions this collection of articles makes to understanding migration, social reproduction and social protection. Migration necessarily involves reconfigurations of family relations and these entail changes in the patterning of social (in)security. Our expansive interpretation of the concepts of social reproduction and social protection situate the reorganisation of gendered family lives as integral to the migration–development nexus. Life-course thinking informs analysis of how migrants ‘do family’ and what this means for gender, identity and (in)security. The collection explores how ‘care deficits’ are managed, both discursively through the negotiation of gendered ideologies about gender identity and the family, and through the everyday practice of social reproduction. The resulting reorganisation of social security involves taking on new risks and vulnerabilities for migrants and their families. For both internal and international migrants the challenges involved in securing social reproduction are powerfully shaped by welfare and migratory regimes and raise important questions about the relationship between social protection and broader social policy and citizenship issues. 相似文献

Previous analyses of Australian samples have suggested that populations of the same broad racial group (Caucasian, Asian, Aboriginal) tend to be genetically similar across states. This suggests that a single national Australian database for each such group may be feasible, which would greatly facilitate casework. We have investigated samples drawn from each of these groups in different Australian states, and have quantified the genetic homogeneity across states within each racial group in terms of the "coancestry coefficient" F(ST). In accord with earlier results, we find that F(ST) values, as estimated from these data, are very small for Caucasians and Asians, usually <0.5%. We find that "declared" Aborigines (which includes many with partly Aboriginal genetic heritage) are also genetically similar across states, although they display some differentiation from a "pure" Aboriginal population (almost entirely of Aboriginal genetic heritage). 相似文献

This article examines relationships between local drug policy (as represented by prosecutor-reported case outcomes for first-offender juvenile marijuana possession cases) and youth self-reported marijuana use, perceived risk, and disapproval. Interviews with prosecutors and surveys of 8th-, 10th-, and 12th-grade students in the United States were conducted in 2000. Analyses include data from 97 prosecutors and students from 127 schools in 40 states. Results indicate significant relationships between local drug policy and youth marijuana use and attitudes. In general, more-severe dispositions are associated with less marijuana use, higher disapproval rates, and increased perceptions of great risk. Associations primarily appear to be specific to marijuana-related outcomes. Results are discussed within the framework of both deterrence and broader social norms regarding substance use. 相似文献

Abstract: There remains significant uncertainty in illicit marijuana cultivation. We analyzed the δ13C and δ15N of 508 domestic samples from known U.S.A. counties, 31 seized from a single location, 5 samples grown in Mexico and Colombia, and 10 northwest border seizures. For a subset, inflorescences and leaves were analyzed separately. These data revealed a strong correspondence, with inflorescences having slightly higher δ13C and δ15N values than leaves. A framework for interpreting these results is introduced and evaluated. Samples identified as outdoor‐grown by δ13C were generally recorded as such by the Drug Enforcement Administration (DEA). DEA‐classified indoor‐grown samples had the most negative δ13C values, consistent with indoor cultivation, although many were also in the outdoor‐grown domain. δ15N indicated a wide range of fertilizers across the dataset. Samples seized at the single location suggested multiple sources. Northwest border δ13C values suggested indoor growth, whereas for the Mexican and Colombian samples they indicated outdoor growth. 相似文献

The psychometric properties and structure of the Cluster B Personality Disorder criteria (Antisocial, Borderline, Histrionic, and Narcissistic) are examined in a sample of 261 female inmates using a self-report screen followed by a full diagnostic interview. The results of the structural analyses in this sample demonstrated good internal consistency and convergence, but poor discriminant validity between disorders. An exploratory factor analysis found that the structure of these disorders was best accounted for by a four-factor solution that paralleled the Diagnostic and Statistical Manual (DSM-IV-TR; APA, 2000) classification scheme with some significant and notable exceptions. Using the factor scores generated from the factor analysis, the personality profiles of the women were compared with several behavioral indices, including instant offense, institutional infractions, and self-report violence and victimization within the prison. Of particular importance was the consistent relationship observed between narcissistic personality traits and threatening and violent behavior within the prison combined with the impulsive but less malignant presentation of antisocial personality traits among this sample of women. Results are discussed as they inform our understanding of the structural integrity of the four Cluster B diagnostic categories and the relationship of these personality disorders to different types of criminality and violence. 相似文献

In mainstream offender samples, several risk assessments have been evaluated for predictive validity. This study extends this work to male offenders with intellectual disabilities. Participants from high-, medium-, and low-security settings, as well as community settings, were compared on a range of risk assessments. The Violence Risk Appraisal Guide, HCR-20-Historical Scale, the Risk Matrix 2000-C (combined risk), and the Emotional Problems Scales-Internalising discriminated between groups, with participants from high security having higher scores than those in medium security, who had higher scores than those in the community. The Violence Risk Appraisal Guide, all HCR-20 scales, the Short Dynamic Risk Scale, and the Emotional Problems Scales (Internalising and Externalising) showed significant areas under the curve for the prediction of violence. The Static-99 showed a significant area under the curve for the prediction of sexual incidents. The discussion reviews the value of these various scales to intellectual disability services. 相似文献
