Controversy concerning the issue of homosexual rights and practiceshas intensified in Britain over the last decade. Despite thisincrease in intensity, however, the question of mass publicopinion in relation to homosexual rights and practices has receivedalmost no empirical investigation. In an effort to remedy thissituation, this article focuses on both the role of respondents'gender as well as their perceptions concerning the gender ofparticipants in a homosexual relationship (both sexes versusgay men) in distinguishing their attitudes toward the publicacceptance of homosexuals and the adoption rights of lesbiansand gay men. Using nationally representative data from the BritishSocial Attitudes Surveys, we found that, whereas both respondents'gender and the gender of participants in a homosexual relationshipdemonstrated a significant influence on attitudes toward thepublic acceptance of homosexuals, they were unrelated to theadoption rights of lesbians or gay men. Even in relation tothe public acceptance of homosexuals, however, gender was notthe only, or even the most important, attribute in distinguishingindividual opinion in this instance. Other stronger and moreconsistent influences were education, age, and attitudes towardeither pre-marital or extra-marital sexual relations. The implicationsof these findings for both policy makers and homosexual activistsare discussed. 相似文献

Validating the Willingness to Self-Censor Scale: Individual Differences in the Effect of the Climate of Opinion on Opinion Expression 总被引:1,自引:0,他引:1
Hayes Andrew F.; Glynn Carroll J.; Shanahan James 《Int. Journal of Public Opinion Research》2005,17(4):443-455
Hayes, Glynn, and Shanahan (2005) defined self-censorship asthe withholding of ones opinion around an audience perceivedto disagree with that opinion. They argued that people differin their willingness to self-censor and introduced an 8-itemself-report instrument, the Willingness to Self-Censor scale,to measure this individual difference. The results of an experimentalstudy presented here provide further evidence of the constructvalidity of the scale. Each participant in the study was presentedwith a hypothetical scenario that contained information suggestinga group of people the participant was conversing with abouta controversial topic held opinions that were either uniformlysimilar to or different from the participants own opinion.Four weeks prior, each participant had responded to the Willingnessto Self-Censor scale and a measure of dispositional shyness.As expected, the manipulation of the climate of opinion affectedwillingness to express an opinion to the group, but more soamong those who scored relatively high on the Willingness toSelf-Censor scale. These results support the notion that somepeople rely on information about the climate of opinion moreso than do others when they decide whether or not to voice theiropinion publicly, and they suggest that the Willingness to Self-Censorscale measures this individual difference. 相似文献

ABSTRACTControl of relative humidity (RH) for collections care is challenging in U.K. historic houses because they are often highly ventilated with poor heat retention, a porous building fabric and naturally tend to high (60–80%) RH if unheated. The significance of the building means that large-scale modifications and installation of air handling systems may be unfeasible and undesirable for the conservation of the building. In the late 1980s the National Trust, for English, Wales and Northern Ireland, investigated conservation heating as an RH control method that works with the natural environment of historic buildings, mimicking historic heating and requiring only modification of existing heating services or a light touch installation of new heating systems. The National Trust adopted conservation heating as its preferred method for environmental control in historic buildings from the 1990s. This method was presented at the IIC 1994 Ottawa congress on preventive conservation. Conservation heating has since been adopted by many historic house management organisations, particularly across north-west Europe, where it is well suited to the climate. This paper reviews conservation heating developments implemented by the National Trust since 1994, in response to a changing external context, new knowledge and developments in operational practice. 相似文献

This study found that mortality salience in TV news activated more hostile attitude toward the perpetrators and negative judgment on the immigration issue. Social group difference influenced news viewers’ immigration issue judgment, but did not affect their resultant hostility and perceived vulnerability. More negative attitudes emerged toward the immigration issue when immigrant perpetrators were portrayed negatively in the news. News viewers with exposure to mortality salience in TV news reported more negative toward immigrants. Exposure to mortality-related elements in TV news could lead to social conflicts that were viewed as a severe threat by U.S. government and policymakers. 相似文献

One impact of globalisation has been the expansion of higher education to meet changing current socio‐economic and political requirements. This expansion places considerable stress on the public purse and many states have turned to alternative solutions. In China, a new phenomenon has emerged: independent higher education institutions that complement public and private institutions in helping to cater for the expanded numbers of students. These independent institutions are formed through partnerships between existing institutions and the business sector. After analysing the political, socio‐economic and cultural contexts that shape the policy of developing independent institutions, this paper explores the dilemmas and challenges that have arisen at the implementation level and critiques some of the solutions that have been found. 相似文献

This study investigated the evolution of physical and technical performances in the English Premier League (EPL), with special reference to league ranking. Match performance observations (n = 14,700) were collected using a multiple-camera computerised tracking system across seven consecutive EPL seasons (2006–07 to 2012–13). Final league rankings were classified into Tiers: (A) 1st–4th ranking (n = 2519), (B) 5th–8th ranking (n = 2965), (C) 9th–14th ranking (n = 4448) and (D) 15th–20th ranking (n = 4768). Teams in Tier B demonstrated moderate increases in high-intensity running distance while in ball possession from the 2006–07 to 2012–13 season (P < 0.001; effect size [ES]: 0.68), with Tiers A, C and D producing less pronounced increases across the same period (P < 0.005; ES: 0.26, 0.41 and 0.33, respectively). Large increases in sprint distance were observed from the 2006–07 to 2012–13 season for Tier B (P < 0.001; ES: 1.21), while only moderate increases were evident for Tiers A, C and D (P < 0.001; ES: 0.75, 0.97 and 0.84, respectively). Tier B demonstrated large increases in the number of passes performed and received in 2012–13 compared to 2006–07 (P < 0.001; ES: 1.32–1.53) with small-to-moderate increases in Tier A (P < 0.001; ES: 0.30–0.38), Tier C (P < 0.001; ES: 0.46–0.54) and Tier D (P < 0.001; ES: 0.69–0.87). The demarcation line between 4th (bottom of Tier A) and 5th ranking (top of Tier B) in the 2006–07 season was 8 points, but this decreased to just a single point in the 2012–13 season. The data demonstrate that physical and technical performances have evolved more in Tier B than any other Tier in the EPL and could indicate a narrowing of the performance gap between the top two Tiers. 相似文献

This essay reviews two recently published American books about masculinity politics—Michael Kimmel's pro-feminist Manhood in America and his edited collection The Politics of Manhood —in order to comment critically on the current debate underway in various parts of the world on 'boys' and their schooling which sees them as the 'new victims' of the educational process. 相似文献

This paper offers a critical analysis of Dubinsky et al. (1994) and proposes, as an alternative to the four axioms and the standard definitions, that permutation and symmetry may be regarded as the fundamental concepts of group theory. 相似文献
