Abstract

A discrete choice experiment was conducted to discover the relative importance of five characteristics of developing countries considered by people when choosing countries to donate money to. The experiment was administered via an online survey involving almost 700 university student participants (potential donors). The most important recipient country characteristic for participants on average is hunger and malnutrition, followed by child mortality, quality of infrastructure, income per capita, and, least importantly, ties to the donor’s home country. A cluster analysis of participants’ individual ‘part worth utilities’ representing the relative importance of the country characteristics reveals they are not strongly correlated with participants’ demographic characteristics.  相似文献

As a form of bias-based harassment, homophobic behavior remains prominent in schools. Yet, little attention has been given to factors that underlie it, aside from bullying and sexual prejudice. Thus, we examined multiple domain general (empathy, perspective-taking, classroom respect norms) and sexual orientation-specific factors (sexual orientation identity importance, number of sexual minority friends, parents’ sexual minority attitudes, media messages). We documented support for a model in which these sets of factors converged to predict homophobic behavior, mediated through bullying and prejudice, among 581 students in grades 9–12 (55 % female). The structural equation model indicated that, with the exception of media messages, these additional factors predicted levels of prejudice and bullying, which in turn predicted the likelihood of students to engage in homophobic behavior. These findings highlight the importance of addressing multiple interrelated factors in efforts to reduce bullying, prejudice, and discrimination among youth.  相似文献

What are the strategic costs of foreign-deployed nuclear weapons? Thus far, scholars have focused primarily on the possible benefits: deterring adversaries and reassuring allies. There is little scholarship on the costs side of the cost–benefit equation. This article evaluates one potential cost: that deployments generate crises. I argue that such deployments have, historically, rarely resulted in crises because few deployments generate the level of threat necessary for the target of the deployment to forcefully act. Crises are likely only in the rare situations when the deployment is to an area that the rival views as vital and the deployment threatens to embolden the deploying or host state. I examine all foreign nuclear deployments to support these claims. The results have implications for ongoing debates on the effects of nuclear weapons and US nuclear deployments abroad today.  相似文献

This article studies the management of territorial claims using an issue-based approach that reconceptualizes processes of interstate conflict and cooperation as reflecting contention over issues. Hypotheses on issue management techniques are tested using newly collected data from the Issue Correlates of War (ICOW) research project. Empirical analysis of territorial claims in the Western Hemisphere supports the general model, with issue salience and past issue interactions systematically affecting states' choices between peaceful and militarized techniques for managing or settling their contentious issues. In particular, action over territorial claims is most likely when more valuable territory is at stake, in the aftermath of militarized conflict, and when recent peaceful settlement attempts have failed. Third parties are more likely to become involved in nonbinding activities when the claim appears more threatening to regional or global stability, and submission of claims to binding third-party decisions is most likely between adversaries that have begun to build up a legacy of successful agreements. The article concludes with a discussion of directions for future research on territory and on other issues.  相似文献

The literature consistently shows an association between pubertal maturation and internalizing problems in girls. The association for boys is less clear. The present study examines genetic and environmental influences on the association between pubertal maturation and internalizing problems for boys and girls in two primarily Caucasian adolescent twin/sibling studies: The Swedish Twin study of CHild and Adolescent Development (706 same-sex twin pairs aged 13-14, M = 13.7 years, 50 % female), and the Nonshared Environment in Adolescent Development sample (US-based, 687 same-sex twin/sibling pairs aged 10-18, M = 13.6 years, 47 % female). For girls, more advanced pubertal maturation was associated modestly with more internalizing problems, and that association was entirely explained by shared environmental influences. For boys, the association between pubertal maturation and internalizing problems was weak and inconsistent. Results for girls were remarkably consistent across samples. Findings suggest that nongenetic mechanisms mediate the association between pubertal maturation and internalizing problems. Findings have implications for intervention such that environmental influences shared by twins/siblings may provide the best targets for intervention strategies designed to minimize the potential negative effects of pubertal maturation on internalizing symptoms in girls.  相似文献

In this essay, the authors explore attitudes toward government privatization of electric utilities across two sets of nations: developed market economies (DMEs) and transition economies (TEs). They utilize generalized hierarchical linear model to analyze individual attitudes nested within these two groups of polities and discover a wide gap between the DME and TE nations in terms of preferences for privatization, with attitudes in DME nations being far more favorable. Attitudes toward the privatization of electricity are explained by a combination of ideological/symbolic predispositions, self-interest, and citizen values/characteristics. The most consistent variables in the model are the ideological/symbolic predispositions, while the weakest are citizen characteristics/values. In terms of self-interest, the analysis indicates that those who work for the public service or a public firm are more likely than others to oppose the privatization of electricity. In contrast to some public administration literature that asserts well-informed and interested citizens will oppose privatization, the authors find no convincing relationships. Instead, the most educated and politically efficacious citizens, as well as those who have confidence in the way democracy works within their nation, are more prone than others to support privatization of electricity.  相似文献

Investment in programs that help Indigenous people undertake work maintaining the environmental health of their country has benefits for the environment as well as the physical, mental and cultural health of the Indigenous people involved. For health these findings have direct implications for some national health policies, service provision to homelands, health promotion and Indigenous health research. There are also direct implications for environmental investment in northern Australia and the design and regulation of markets in resource entitlements. Indirectly the findings should be important for economic, employment and education policies as well as those promoting social harmony. Given the range of benefits there is a strong argument for cross-agency investment in working on country by Indigenous people.  相似文献

This article examines how the Commonwealth Parliament of Australia seeks to hold responsible ministers directly and senior public servants indirectly accountable for the performance of departments and programs on the basis of published performance data and inquiries conducted by parliamentary committees. From the perspective of an outsider, the scrutiny process in the Australian parliament, although not without its problems, is more systematic and substantive than is the case in other parliamentary systems such as Canada. Creating a more meaningful dialogue in the Australian parliament on performance issues will depend more on changes to the intersecting cultures of the legislature, government and the public service than on organisational and procedural reforms to any of those institutions.  相似文献
