This study examines whether negative social contextual stressors were associated with somatic symptoms among young Black males (N = 74) after accounting for background and psychological characteristics. Using Cunningham and Spencer’s Black Male Experiences Measure, negative social contextual stressors connoted those experiences connected to the personal attributes, devaluation, and negative imagery of young Black males, such as being followed when entering a store or police or security guards asking them what they are doing when hanging out (e.g., in the park or playground or on the street corner). Results showed that such stressors made a unique and significant contribution to the experience of somatic symptoms. Future research directions and implications for addressing the larger societal perceptions of young Black males are discussed.  相似文献

The treatment of population issues in modern fiction is examined under three headings: fear of population decline, fear of population excess, and fear of population professionals. Writings on population decline cover both the depopulation caused by too‐low fertility and science‐fictional scenarios of natural or human‐made demographic catastrophes. Population excess is chiefly portrayed through ecological dystopias, but includes also depictions of unchecked immigration from poor to rich countries. Population professionals as fictional protagonists range from villainous biomedical and social engineers to feckless family planning workers.  相似文献

Drawing on a recent national survey, this article focuses on the female representation on executive committees in French voluntary associations. To begin with, we observe that this representation is very unequal according to the different officer positions. It is especially low among presidents while it is markedly higher among secretaries. Then, we study the relationship between the associations’ attributes and the likelihood of women being appointed as executive committee members. Our investigation bears out some findings from previous studies on nonprofit female leadership. For instance, we show that the proportion of female officers is higher in organizations whose activities pertain to social service, health, and humanitarian sectors. It is lower in the oldest associations and it decreases as their geographical area of activity increases and as their budget becomes larger. But we also emphasize new results. First, the probabilities that women hold president, treasurer and secretary positions are highly correlated to each other. Second, the likelihood that associations have female presidents is higher in associations with few volunteers. We consider possible explanations for the latter result.  相似文献

This study develops an economic ordering policy of a deteriorating item with a constant production and demand rate. By considering the view of both the vendor and buyer, a mathematical model subject to single-vendor-single-buyer and multiple deliveries per order is developed. It can be shown that the integrated approach results in an impressive cost-reduction compared with an independent decision by the buyer.  相似文献

This article will summarise the results of The Netherlands pilot study commissioned by the Dutch Ministry of Housing, Spatial Planning and the Environment, and carried out by the Dutch National Institute of Public Health and the Environment (RIVM). This pilot study differed from existing sustainable transport scenario studies for four reasons: (i) very sharp emission reductions are assumed, (ii) not only 'forecasting' but also 'backcasting' scenarios are constructed, (iii) instrument packages and implementation time paths are described which - if carried out - would result in the necessary technological and behavioural changes to realize environmentally sustainable transport, and (iv) the social and economic impact of sustainable transport is assessed.  相似文献

Abstract It is increasingly recognized that families and communities are important in helping youths develop the knowledge and skills they need to obtain technologically sophisticated jobs, which are an emerging part of the global economy. In this paper we adopt social capital as a framework for examining the influence of family and community on promoting educational achievement among public school students. We explore more fully the role of community social capital in influencing educational performance beyond that attributed to family social capital. Using data from the National Education Longitudinal Survey (NELS), we find that both process and structural attributes of family social capital are key factors affecting high school students' educational achievement. Process and structural attributes of community social capital also help youths to excel, though they contribute less strongly to achievement. These findings suggest that policies designed to promote educational achievement must extend beyond the school and must seek to strengthen social capital in the family and the community.  相似文献
