This research surveys the literature around black consumerism and social movements, exploring the “Don’t Buy Where You Can’t Work” (DBWYCW) campaigns of the 1920s-1940s. The author examines the integral roles women played (as organizers, agitators, and beneficiaries) in various economic boycotts within the context of Belinda Robnett’s theory of bridge leadership, with a particular focus on consumerism as a major vehicle through which African-American women engaged in movement work during the DBWYCW campaigns. This article challenges the erasure of women’s leadership by reframing “Don’t Buy” as a women’s movement. Applying Robnett’s bridge leadership theory to different eras, regions, and movements, we see how the Great Depression combined with activism in the gendered sphere of consumerism and facilitated the activism of black women. This paper also expands Robnett’s conceptualization of professional and indigenous bridge leaders by identifying urban working class women within the “Don’t Buy” movement who fit these leadership categories.  相似文献

The objective of this work was to summarise and evaluate the evidence showing that physical activity is a protector factor as regards falls in older people. Relevant studies were identified through a systematic search in the MEDLINE and Cochrane Library, under the keywords of accidental fall/numerical data and risk factors, and with the bibliographies of retrieved papers. The combined odds ratio (OR) [95% confidence interval] for physical activity was 0.75 [0.64, 0.88] with moderate heterogeneity (I 2?=?33%). For fall injury, it was 0.59 [0.47, 0.74] and, for falls in general, it rose to 0.94 [0.76, 1.17] with nil heterogeneity. The combined OR for sedentary factors was 1.14 [1.10, 1.82] with moderate heterogeneity (I 2?=?36%). Regular physical activity in daily life yields significant reduction in falls in older people, especially falls with injuries.  相似文献

ABSTRACT

Social workers can mobilize vulnerable populations to shape policy decisions about industrial practices that could have adverse impacts on their wellbeing. One such practice is hydraulic fracturing or “fracking” to extract oil and natural gas from shale rock deposits. There is scant social work literature on mobilizing opposition to fracking despite a proliferation of literature from other disciplines. This article documents the campaign in Maryland that led to the adoption of the first legislative ban on fracking in a U.S. state with shale gas reserves, using social movement theory to identify factors that led to this successful outcome.  相似文献

An enterprise culture is one in which ‘certain enterprising qualities — such as self reliance, personal responsibility, boldness and a willingness to take risks in the pursuit of goals — are regarded as human virtues and promoted as such’. Work is not seen as a constraint upon the individual but rather as an opportunity for self‐fulfilment. The pervasiveness of enterprise culture has led to observations that it influences aspects of social life beyond the workplace. However, the kind of self that is imagined in enterprise culture is also a male self, with female entrepreneurship measured against a male norm. In this article, then, we present evidence of metaphor as a strategy for coping with the gendered expectations embodied by life in enterprise culture. We show how metaphor is simultaneously an index of and a resource for understanding gendered subjectivities in enterprise culture.  相似文献

Federal and other regulatory agencies often use or claim to use a weight of evidence (WoE) approach in chemical evaluation. Their approaches to the use of WoE, however, differ significantly, rely heavily on subjective professional judgment, and merit improvement. We review uses of WoE approaches in key articles in the peer‐reviewed scientific literature, and find significant variations. We find that a hypothesis‐based WoE approach, developed by Lorenz Rhomberg et al., can provide a stronger scientific basis for chemical assessment while improving transparency and preserving the appropriate scope of professional judgment. Their approach, while still evolving, relies on the explicit specification of the hypothesized basis for using the information at hand to infer the ability of an agent to cause human health impacts or, more broadly, affect other endpoints of concern. We describe and endorse such a hypothesis‐based WoE approach to chemical evaluation.  相似文献

The study sought to examine young people’s life satisfaction in the context of the family environment, using data from the 2006 HBSC: WHO-collaborative Study in Scotland (N = 5,126). Multilevel linear regression analyses were carried out for 11-, 13- and 15-year old boys and girls, with outcome measure ridit-transformed life satisfaction. The study found there to be a relationship between family structure and life satisfaction for boys and girls aged 13 and 15 years. Family affluence mediated this relationship, however the extent of this mediation depended both on age and gender. For both boys and girls at all ages, life satisfaction was more strongly associated with parent–child communication than with family structure or family affluence. After adjustment for risk/health behaviours and attitudes towards peers and school, family structure remained significant for boys aged 13 years only. Whereas difficult parent–child communication acted as a risk factor of low life satisfaction for boys and girls, easy communication acted as protective factor among girls only.  相似文献

This article compares mothers’ experience of having children with more than one partner in two liberal welfare regimes (the United States and Australia) and two social democratic regimes (Sweden and Norway). We use survey-based union and birth histories in Australia and the United States and data from national population registers in Norway and Sweden to estimate the likelihood of experiencing childbearing across partnerships at any point in the childbearing career. We find that births with new partners constitute a substantial proportion of all births in each country we study. Despite quite different arrangements for social welfare, the determinants of childbearing across partnerships are very similar. Women who had their first birth at a very young age or who are less well-educated are most likely to have children with different partners. The educational gradient in childbearing across partnerships is also consistently negative across countries, particularly in contrast to educational gradients in childbearing with the same partner. The risk of childbearing across partnerships increased dramatically in all countries from the 1980s to the 2000s, and educational differences also increased, again, in both liberal and social democratic welfare regimes.  相似文献

Decision analysis tools and mathematical modeling are increasingly emphasized in malaria control programs worldwide to improve resource allocation and address ongoing challenges with sustainability. However, such tools require substantial scientific evidence, which is costly to acquire. The value of information (VOI) has been proposed as a metric for gauging the value of reduced model uncertainty. We apply this concept to an evidenced‐based Malaria Decision Analysis Support Tool (MDAST) designed for application in East Africa. In developing MDAST, substantial gaps in the scientific evidence base were identified regarding insecticide resistance in malaria vector control and the effectiveness of alternative mosquito control approaches, including larviciding. We identify four entomological parameters in the model (two for insecticide resistance and two for larviciding) that involve high levels of uncertainty and to which outputs in MDAST are sensitive. We estimate and compare a VOI for combinations of these parameters in evaluating three policy alternatives relative to a status quo policy. We find having perfect information on the uncertain parameters could improve program net benefits by up to 5–21%, with the highest VOI associated with jointly eliminating uncertainty about reproductive speed of malaria‐transmitting mosquitoes and initial efficacy of larviciding at reducing the emergence of new adult mosquitoes. Future research on parameter uncertainty in decision analysis of malaria control policy should investigate the VOI with respect to other aspects of malaria transmission (such as antimalarial resistance), the costs of reducing uncertainty in these parameters, and the extent to which imperfect information about these parameters can improve payoffs.  相似文献
