We consider a simple production model and we assume that agents have unequal production skills which can in no way be attributed
to their responsibility. We study how it is possible, if at all, to compensate for differential skills by applying Rawls's
idea of a collective sharing in the benefits of skills. For this purpose, we introduce an axiom of solidarity, according to
which agents should all be affected in the same direction if the profile of personal skills changes. We show that particular
allocation rules are characterized be combining this axiom with a requirement of non-discrimination among preferences, or
with a property capturing Nozick's idea of guaranteeing a minimal benefit from one's own skill.

Cross‐sectional research has shown a link between adolescent substance use and educational motivation. The purpose of the current study was to examine this link in a longitudinal sample of African American youth. The study examined the interrelationships between alcohol and both marijuana use and school motivation over the high school years and their effect on graduation in 681 African American adolescents (50.8% female). School motivation was shown to relate to subsequent alcohol use throughout high school and marijuana use early in high school. School motivation did not affect graduation status, but alcohol and marijuana use were related to a lower likelihood of graduating from high school. Some gender differences and differences among those who had tried alcohol or marijuana at the first wave as opposed to those who had not tried each substance were found. The findings support a systems model where school experiences can affect substance use, which, in turn, can affect the completion of high school. 相似文献

In this article, we investigate the effect of individual and community level characteristics on subjective well-being in Belgium.
Various indicators for subjective well-being are being used in a multilevel analysis of the 2009 SCIF survey (n = 2,080) and the 2006 Belgian ESS sample (n = 1,798). On the individual level, most hypotheses on the determinants of subjective well-being were confirmed. Living with
a partner and age were shown to have strong effects, but also social capital indicators had a significant positive effect
on subjective well-being. All these effects remained significant controlling for optimism. On the community level, especially
unemployment rate had a negative impact on subjective well-being. The analysis further demonstrates that in homogeneous regions,
community characteristics have a far weaker impact on subjective well-being indicators than in economically more heterogeneous
regions. 相似文献

In organ transplantation, placebo-controlled clinical trials are not possible for ethical reasons, and hence non-inferiority trials are used to evaluate new drugs. Patients with a transplanted kidney typically receive three to four immunosuppressant drugs to prevent organ rejection. In the described case of a non-inferiority trial for one of these immunosuppressants, the dose is changed, and another is replaced by an investigational drug. This test regimen is compared with the active control regimen. Justification for the non-inferiority margin is challenging as the putative placebo has never been studied in a clinical trial. We propose the use of a random-effect meta-regression, where each immunosuppressant component of the regimen enters as a covariate. This allows us to make inference on the difference between the putative placebo and the active control. From this, various methods can then be used to derive the non-inferiority margin. A hybrid of the 95/95 and synthesis approach is suggested. Data from 51 trials with a total of 17,002 patients were used in the meta-regression. Our approach was motivated by a recent large confirmatory trial in kidney transplantation. The results and the methodological documents of this evaluation were submitted to the Food and Drug Administration. The Food and Drug Administration accepted our proposed non-inferiority margin and our rationale. 相似文献

Till now, the relation between schooling and social mobility, a classical question in the sociology of education, has been approached through analyses of a structural sort, either by focusing on the functions that schools are supposed to fill or by adopting the timeless model of neoclassical economics. This approach does not examine all possible relations between schools and social mobility; nor does it see these relations in terms of a process. A study of the scholastic biographies of the children of farmers and workers in western France renews our conception of this relation. It shows that this relation mainly stems from a combination of quite heterogeneous elements, which we glimpse in these biographies. 相似文献

We examine several potential mechanisms linking religious involvement to depressive symptoms, major depression, and anxiety. Logistic and OLS regression estimations test five sets of potential psychosocial religion mediators: perceived attitudes toward and motivations for attendance; positive and negative religious coping; religious attitudes, beliefs, and spirituality; congregational support and criticism; and interpersonal and self-forgiveness. Compared to attending services less than once a month or never, attending services once a week but no more is associated with fewer depressive symptoms and anxiety symptoms. Hypothesized mediators, including meaning, interpersonal and self-forgiveness, congregational criticism, social attendance beliefs, and negative coping are independently associated with one or more mental health outcomes. 相似文献

The purpose of the article is to examine whether an acculturation of trust takes place among non-western immigrants upon migrating to Western Europe and whether inclusionary integration policies have an effect on this process. Building on the second and third wave of the European Social Survey (ESS) we show that an acculturation of trust does take place, but that integration policy does not affect this process. In spite of some variation across destination countries, we also find that second generation immigrants tend to adapt more to the level of trust of natives in the destination country than first generation immigrants do. This indicates that the acculturation of trust is strengthened with the second generation in the country. The results hold up when controlling for confounding variables including the trust in the country of origin of immigrants. 相似文献

The working‐class is typically regarded as the driving force of welfare state development. Yet, some argue that the middle‐classes' beneficial involvement in the welfare state is crucial for its financial sustainability and popular legitimacy. Against this backdrop, we investigate how recent welfare state reforms in Germany which affect the status of the middle‐class are viewed and discussed by this group. Germany is a particularly interesting case because its welfare state is seen to be centred on the desires of the middle‐class, especially through its focus on status maintenance and horizontal redistribution over the life‐course. However, the move from status maintenance to minimum income support in unemployment provision and the strengthening of private old age provision challenge this assumption. Thus, we ask how the German middle‐class views the emerging abandonment of the principle of status maintenance and the shift from collective to individual responsibility. Based on qualitative material from focus groups, we find that individual responsibility is generally supported, but that the state is still assigned responsibility for providing basic levels of social security. Furthermore, for those groups seen as less capable of acting individually responsible (e.g. the poor or long‐term unemployed) the ‘inducement’ of – or assistance for – individually responsible behaviour by the state is demanded. Overall, while the principle of ‘individual responsibility’ seems to find some resonance among the middle‐class members interviewed, they still try to balance individual and collective responsibility. 相似文献
