Individual citizens are the largest source of contributions for congressional candidates in the United States. This paper investigates if and how fundraising from this source is related to the ideological positions of candidates. Specifically, we ask whether the amount of contributions depends on: (1) the extremity of candidate ideology; and (2) the level of candidate divergence in the same race. These results have important implications for candidate positioning strategies, as well as for evaluating the effects of recent campaign finance reforms.  相似文献

A positive, statistical and economic significant relation between growth, income level and the Economic Freedom of the World (EFW) index has been amply documented. Most analyses, however, use OLS methods which, in the presence of endogenous variables do not establish causality and produce biased and inconsistent estimates. This paper uncovers the exogenous component of EFW using IV methods and finds a robust channel from economic freedom to prosperity. The findings, including instrument validity tests, support the importance of policies and institutions for development and warrants policy advice aimed at increasing economic freedom to foster prosperity.  相似文献

In this paper, we examine whether the impact of negative advertising on citizens’ evaluations of candidates depends on the gender of the candidates. Given common gender stereotypes, we expect negative campaigning aimed at women candidates will affect citizens differently than negative campaigning against male candidates. The results of our study, derived from a survey experiment conducted on a nationwide sample of more than 700 citizens, demonstrate that negative commercials are less effective at depressing evaluations of woman candidates, compared to male candidates. The findings are consistent and strong, across a range of forces that people use to assess competing candidates (i.e., affect and trait evaluations, people’s beliefs about issues, anticipated vote choice). The tight control of the experimental design, including randomization of respondents into different conditions that vary in only one way, demonstrates that the gender of the candidate influences people’s reactions to different types of negative commercials.

From 9/11 in the U.S. to train, subway, and airport bombings elsewhere, individuals frequently must make political decisions in the shadow of terrorist attacks. To date, few studies have examined how times of terror threat influence voters’ decision-making processes. Using data generated from three experiments we show that, in times of terrorist threat (compared to good times), individuals weight leadership more heavily in the voting booth. Our results also shed light on how much weight is given to other determinants of the vote (issues and partisanship) across these two conditions.  相似文献

This article takes a state's eye view of trends towards a more centralised system of governance in Australia. It argues that while globalisation strengthens the roles of national governments it also provides less noticed public policy and management opportunities for sub-national governments. The article shows how state governments in Australia can use high-level policy proposals to reinforce their continuing relevance as key members of a federal system of government. It proposes that skilful deployment of policy ideas and analyses can enable the states to sustain alternative national agendas despite hostility or lack of interest by the federal government. In conclusion, the article examines the implications for federal-state relations under the Rudd government. It suggests that the elements for productive reform agendas are present but that bringing them together will require considerable effort.  相似文献

Children of immigrants who do translations and who interpret for others using their heritage language and English are known as language brokers. Although prior research suggests that children of immigrants’ perceptions of the language brokering experience vary greatly—from feeling a sense of efficacy to feeling a sense of burden—what remains unanswered in the literature is identification of the antecedents and processes that help to explain the varying psychological experience of language brokers. Using data from a two-wave prospective longitudinal study of 256 Chinese American adolescents, the present study tested potential mechanisms that may be responsible for adolescents’ perceptions of the language brokering experience as a sense or burden or sense of efficacy. The results demonstrate that adolescents’ Chinese orientation sets in motion a family process that is linked to variations in the perceptions of adolescents’ language brokering experience. Adolescents who are more Chinese oriented have a stronger sense of familial obligation, and these adolescents are more likely to perceive that they matter to their parents. Adolescents’ perceived sense of mattering to parents, in turn, is associated positively with a sense efficacy, and negatively with a sense of burden as language brokers. Those adolescents who are less Chinese oriented have a weaker sense of familial obligation, and these adolescents are more likely to feel a sense of alienation from their parents. Adolescents’ sense of perceived alienation from parents, in turn, is associated with a sense of burden as language brokers. Implications for developing interventions for children who act as language brokers for their parents are discussed.

Self-determination theory emphasizes the importance of school-based autonomy and belongingness to academic achievement and psychological adjustment, and the theory posits a model in which engagement in school mediates the influence of autonomy and belongingness on these outcomes. To date, this model has only been evaluated on academic outcomes. Utilizing short-term longitudinal data (5-month timeframe) from a set of secondary schools in the rural Midwest (N = 283, M age = 15.3, 51.9% male, 86.2% White), we extend the model to include a measure of positive adjustment (i.e., hope). We also find a direct link between peer-related belongingness (i.e., peer support) and positive adjustment that is not mediated by engagement in school. A reciprocal relationship between academic autonomy, teacher-related belongingness (i.e., teacher support) and engagement in learning is supported, but this reciprocal relationship does not extend to peer-related belongingness. The implications of these findings for secondary schools are discussed.
