Municipal day care services for children in Norway have experienced two important reforms: the introduction of the Kindergarten Act in 1975, and the introduction of preschools for 6-year-olds in 1991. Focusing on the relationship between environmental inputs and policy outcomes, this article attempts to identify characteristics influencing the propensity towards early provision of day care in the municipalities. Applying logistic regression, service-specific factors show the greatest importance, as opposed to more general municipal features. The political system, in terms of high female representation and low representation from the Christian Democratic Party, the Center Party, and the Progress Party in local councils, seems responsive to the proportion of children, the percentage of women working full time, and average net income per capita. The persisting importance of gender-specific variables is discussed – suggesting different interpretations of the results in relation to the feminization of politics.  相似文献

Objectives. This article tests the hypothesis that social capital—measured in terms of civic group involvement, social and racial trust, and political engagement—leads to charitable behavior by individuals. Methods. I introduce measures of the “social capital elasticity of giving,” which facilitate comparisons between the effects on charity of different social capital types. Using data from the 2000 Social Capital Community Benchmark Survey, I estimate these elasticities with tobit regression models. Results. I find strong links between changes in social capital stocks and changes in giving levels. Furthermore, I find that different social capital types have differing levels of impact on giving. Conclusions. Charitable giving appears to be a beneficial consequence of some types of social capital.  相似文献

Although analyses about what representative individuals would choose behind the veil of ignorance have been regarded as n-person non-zero-sum cooperative games, none of the apparatus of game theory beyond 2-person non-zero-sum noncooperative games has actually been used. The grand coalition of all representative individuals emerges from behind the veil of ignorance to form a society unanimously. This paper investigates the consequences of extending the original position to allow three persons the possibility of forming binding coalitions behind the veil of ignorance. Just enough information and structure is added to the traditional analysis, to make bargaining feasible. The result is that whether or not representative individuals know the payoff structure for forming a society, a stable unanimous agreement may not emerge. The analysis shows yet another way in which original position arguments are sensitive to assumptions about information and criteria of rational decision behind the veil of ignorance.  相似文献

This article reviews a variety of ethical issues one must consider when conducting research on environmental health interventions on human subjects. The paper uses the Kennedy Krieger Institute lead abatement study as well as a hypothetical asthma study to discuss questions concerning benefits and risks, risk minimization, safety monitoring, the duty to warn, the duty to report, the use of control groups, informed consent, equitable subject selection, privacy, conflicts of interest, and community consultation. Research on environmental health interventions can make an important contribution to our understanding of human health and disease prevention, provided it is conducted in a manner that meets prevailing scientific, ethical, and legal standards for research on human subjects.  相似文献

The complexities that converge around palliative sedation invite clinicians to work together to differentiate the issues and come to recommendations and decisions that are humane, ethical, legal, and clinically sound. Whether a crisis or long-term situation exists, the work is essentially the same. It must include critical thinking, clinical expertise, multidimensional assessment, and an array of interventions to assist patients and families in situations where symptoms and suffering are sufficiently intense to warrant exploration of sedation. The many issues inherent in the discussion of sedation at end of life require not that we have the answers but rather that we work with our colleagues to raise relevant questions and integrate both expertise and compassion into end-of-life decisions and care.  相似文献

Objective. This research explores the seldom‐addressed question of whether teacher‐student racial congruence conditions the impact of teacher perceptions on performance. Methods. Multipopulation LISREL models (utilizing data from the NELS) compare the effect of white teachers' perceptions on African‐American standardized test performance to the corresponding effect among white students. Parallel models compare the impact of African‐American teacher perceptions across races. Preliminary models gauge whether the match/mismatch of teacher's and student's race shapes teacher perceptions of African‐American and white students. Results. The impact of teachers' perceptions on test performance shows signs of being especially pronounced in the racially dissonant white teacher‐black student context—the very context where teacher perceptions seem especially likely to be unfavorable. Conclusions. This research provides new insight on the relevance of teacher perceptions to the black‐white performance gap. Racial congruence seems primarily consequential to African‐American test performance—shaping both teacher perceptions and (somewhat less so) the impact of such perceptions on performance.  相似文献

The main issues in relation to the provision of health and social welfare services for migrants in Australia are: (a) to ensure access and equity; (b) concern about the relatively high proportions of some groups from specific birthplaces requiring support; and (c) the complexity and costs of ethnically specific services. This article focuses on the major pensions and benefits paid by the Department of Social Security, particularly the age pension and unemployment benefit. It also examines the interrelationship between mortality, morbidity, private health insurance, use of health services and the proportions on health-related pensions. Linked with these issues is the debate about an appropriate level of immigration when the unemployment rate is high, as in the current recession, and when new arrivals have little prospect of finding a job. A second major concern is the cost of caring for elderly immigrant parents who have come to Australia under the family reunion program.  相似文献

Two themes in the theory of measurement that have been studied extensively in the past few years are numerical representations of nontransitive binary comparison structures and uniqueness in finite measurement systems. This paper brings the two together by exploring the solutions to a nontransitive, additive model that are unique up to multiplication by a positive constant. The model relates to various contexts including decision under risk, evaluation of objectives, comparative probability, and voting theory. The family of unique solutions for the model is shown to be extremely rich and varied.  相似文献
