Scaling methods pioneered by Poole and Rosenthal (Am J Polit Sci 29(2):357–384, 1985) redefined how scholars think about and estimate the ideologies of representatives seated in the US Congress. Those methods also have been used to estimate citizens’ ideologies. Whereas studies evaluating Congress typically use a behavioral measure, roll call votes, to estimate where representatives stand on the left-right ideological spectrum, those of the public most often have relied on survey data of stated, rather than revealed, preferences. However, measures of individuals’ preferences and, accordingly, estimates of their ideal points, may differ in important ways based on how preferences are elicited. In this paper, we elicit the same individuals’ preferences on the same 10 issues using two different methods: standard survey responses measured on a Likert scale and a donation exercise wherein individuals are forced to divide $1.50 between interest groups with diametrically opposed policy preferences. Importantly, expressing extreme views is costless under the former, but not the latter, method. We find that the type of elicitation method used is a significant predictor of individuals’ ideal points, and that the elicitation effect is driven primarily by Democratic respondents. Under the donation method, the ideal points of Democrats in the aggregate shift left, particularly for those Democrats who are politically engaged. In contrast, wealthy Democrats’ ideal points shift to the right. We also document effects for Republicans and Independents and find that overall polarization is similar under both elicitation methods. We conclude with a discussion of our results, and the consequences and tradeoffs of each elicitation method. 相似文献

The article scrutinizes the emergence and expansion of EU-related professions and forms of occupation from a field-analytical perspective. Starting from the observation that the EU is not just an influential political actor, but also an expanding area of work, expert involvement and job specialization the paper discusses various forms, dimensions and loci of the ongoing “professionalization” of Europe. It is shown that the expansion of EU-related professional activities is not just a phenomenon of Brussels and the “Eurocracy”, but has expanded into the member states and various areas of occupational activity and expertise. The EU professionalization is conceptualized as a transnational field of specialization and professionalization which produces own principles, forms of knowledge and resources which are used and reproduced by experts and specialists. The field perspective allows identifying common principles, but also the variance and transnational dimension of EU affairs. 相似文献

Gender awareness and gender neutrality are discussed with the aid of post‐structuralist gender theories concerning paradoxes and aporias. Via paradox thinking, women's, men's and gender studies are challenged to develop perspectives on gender that are both thought and not thought, said and not said, done and not done. Paradoxes are understood as aporias, in which the researcher gets into “stuck places”. Gender dualism is put to the test as a fundamental concept. Various theories of power, such as patriarchy theories, theories of hegemonic power, and gender and queer‐theories of symbolic and discursive power are associated with gender paradoxes and gender dualism. Examples are included from the author's own research in school and gender studies. 相似文献

The risk for depression increases as Hispanic youth acculturate to U.S. society. This association is stronger for Hispanic girls than boys. To better understand the influence of culture and family on depressive symptoms, we tested a process-oriented model of acculturation, cultural values, and family functioning. The data came from Project RED, which included 1,922 Hispanic students (53?% girls; 86?% were 14?years old; and 84?% were U.S. born) from Southern California. We used data from 9th to 11th grade to test the influence of acculturation-related experiences on depressive symptoms over time. Multi-group structural equation analysis suggested that both family conflict and cohesion were linked with depressive symptoms. Hispanic cultural values were associated with family cohesion and conflict but the strength and direction of these relationships varied across cultural values and gender. For girls and boys, familismo and respeto were associated with higher family cohesion and lower family conflict. Moreover, gender roles were linked with higher family cohesion in girls but not in boys. These results indicate that improving family functioning will be beneficial for boys' and girls' psychological well-being. This may be achieved by promoting familismo and respeto for boys and girls and by promoting traditional gender roles for girls. 相似文献

Suicide is a leading cause of death among adolescents, many of whom fail to disclose suicide concerns to adults who might help. This study examined patterns and predictors of help-seeking behavior among adolescents who seriously considered suicide in the past year. 2,737 students (50.9?% female, 46.9?% male; racial distribution 79.5?% Caucasian, 11.9?% Hispanic/Latino, and 3.6?% Black/African-American) from 12 high schools in rural/underserviced communities were surveyed to assess serious suicide ideation (SI) in the past year, disclosure of SI to adults and peers, attempts to get help, attitudes about help-seeking, perceptions of school engagement, and coping support. Help-seeking was defined as both disclosing SI to an adult and perceiving oneself as seeking help. The relationship between adolescents' help-seeking disclosure and (1) help-seeking attitudes and (2) perceptions of social resources was examined among suicidal help-seeking youth, suicidal non-help-seeking youth, and non-suicidal youth. Of the 381 (14?%) students reporting SI, only 23?% told an adult, 29?% sought adult help, and 15?% did both. Suicidal help-seekers were similar to non-suicidal peers on all measures of help-seeking attitudes and social environment perceptions. Positive attitudes about help-seeking from adults at school, perceptions that adults would respond to suicide concerns, willingness to overcome peer secrecy requests, and greater coping support and engagement with the school were associated with students' increased disclosure of SI and help-seeking. This study supports prevention strategies that change student norms, attitudes and social environments to promote help-seeking among adolescents with SI. Promising intervention targets include increasing students' perceptions of the availability and capability of adults to help them, and strengthening students' understanding of how existing resources can help them cope. 相似文献
