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

Data sets with excess zeroes are frequently analyzed in many disciplines. A common framework used to analyze such data is the zero-inflated (ZI) regression model. It mixes a degenerate distribution with point mass at zero with a non-degenerate distribution. The estimates from ZI models quantify the effects of covariates on the means of latent random variables, which are often not the quantities of primary interest. Recently, marginal zero-inflated Poisson (MZIP; Long et al. [A marginalized zero-inflated Poisson regression model with overall exposure effects. Stat. Med. 33 (2014), pp. 5151–5165]) and negative binomial (MZINB; Preisser et al., 2016) models have been introduced that model the mean response directly. These models yield covariate effects that have simple interpretations that are, for many applications, more appealing than those available from ZI regression. This paper outlines a general framework for marginal zero-inflated models where the latent distribution is a member of the exponential dispersion family, focusing on common distributions for count data. In particular, our discussion includes the marginal zero-inflated binomial (MZIB) model, which has not been discussed previously. The details of maximum likelihood estimation via the EM algorithm are presented and the properties of the estimators as well as Wald and likelihood ratio-based inference are examined via simulation. Two examples presented illustrate the advantages of MZIP, MZINB, and MZIB models for practical data analysis. 相似文献

This article undertakes a diagnostic study of the Technical and Vocational Education and Training (TVET) sub‐sector in Uganda, with a view to characterizing the sub‐sector and identifying its potential strengths and weakness. We undertook a cross‐sectional pre‐survey of purposively selected key stakeholders in the TVET sub‐sector. We selected performance indicators following their importance in influencing the TVET reform process. Both qualitative and quantitative data was solicited from the stakeholders. Quantitative data was collected through stakeholder‐specific structured questionnaires, whilst qualitative data was collected through desk review and field visits, individual focused interviews and focus group discussions. Our findings indicate that financing and planning constraints have resulted in poor quality equipment, under‐ and ill‐trained staff, limited adoption of a competence‐based education and training (CBET) curriculum, not to mention the supervision inadequacies of TVET institutions. Besides, the limited TVET sub‐sector interaction with the private sector has incapacitated TVET curriculum development to nurture skills demanded by the private sector. Furthermore, backward technology use in the private sector has equally inhibited the success of student attachment programmes. Finally, legal ambiguities have perpetuated a qualification jungle and overlapping curricula. 相似文献

Information Seeking about Global Climate Change among Adolescents: The Role of Risk Perceptions, Efficacy Beliefs and Parental Influences 总被引:2,自引:0,他引:2

Global climate change is likely to have significant impacts on public health. Effective communication is critical to informing public decision making and behavior to mitigate climate change. An effective method of audience segmentation, the risk perception attitude (RPA) framework has been previously tested with other health behaviors and classifies people into 4 groups on the basis of their perceptions of risk and beliefs about personal efficacy. The 4 groups - indifference (low risk, weak efficacy), proactive (low risk, strong efficacy), avoidance (high risk, weak efficacy), and responsive (high risk, strong efficacy) - are hypothesized to differ in their self-protective behaviors and in their motivations to seek information. In this paper, we extend the RPA framework in two ways. First, we use it at the household level to determine whether parental classifications into the 4 groups are associated with their teenage children's classification into the same 4 groups. Second, we predict adolescent information-seeking behaviors on the basis of their and their parents' membership in the 4 RPA groups. Results (N = 523 parent-adolescent pairs) indicated that parental membership in the 4 RPA groups was significantly associated with children's membership in the same 4 groups. Furthermore, the RPA framework was a significant predictor of adolescent information-seeking: those in the responsive and avoidance groups sought more information on climate change than the indifference group. Family communication on global warming was positively associated with adolescents' information-seeking. Implications for interventions are discussed. 相似文献

This paper reviews controversies about domestic violence occurring in heterosexual relationships discussed in the Australian context by practitioners and academics and published in the Australian & New Zealand Journal of Family Therapy over the past three decades. Controversies arose in relation to the provision of therapeutic interventions for domestic violence, primarily in individual and couple counselling and group programs. After a literature review, the following controversial issues are identified: (1) the role of patriarchy: Is a patriarchal culture the main cause of domestic violence? (2) Systemic family therapy and gendered violence: Does systemic family therapy hide men's responsibility for domestic violence? (3) Therapeutic and educational interventions for domestic violence: Does therapy turn a ‘crime’ into a ‘psychological problem’? (4) Men as victims: Do both men and women perpetrate domestic violence in equal measure? (5) It takes two to tango: What part do women play in eliciting men's violence? 相似文献

Ageism is an important topic in our society, considering the burgeoning older adult population. Ageism is often measured using explicit questionnaires; however, given the impact of social desirability, implicit measures of ageism have been developed. In this study, the contradiction paradigm, an implicit measure of stereotypes (Lassonde, under review) was used to measure age-related stereotypes in passages describing older adults. Participants read passages with target sentences more slowly when these sentences described behaviors that were inconsistent rather than consistent with age-related stereotypes. Participants also completed a series of self-report questionnaires measuring ageism. Results demonstrated that reading times using the contradiction paradigm were not related to outcomes on the self-report questionnaires. A comparison of the contradiction paradigm to a social desirability scale revealed that it was not vulnerable to social desirability. This confirms the contradiction paradigm's use as an implicit measure of age-related stereotypes. Although there is no clear relation between the contradiction paradigm and popular explicit measures, a next important step would be to determine the point in which implicit knowledge and intentional behavioral responses interact. 相似文献

This article reexamines the living arrangements of children following their parents’ divorce, using Wisconsin Court Records, updating an analysis that showed relatively small but significant increases in shared custody in the late 1980s and early 1990s. These changes have accelerated markedly in the intervening years: between 1988 and 2008, the proportion of mothers granted sole physical custody fell substantially, the proportion of parents sharing custody increased dramatically, and father–sole custody remained relatively stable. We explore changes in the correlates of alternative custody outcomes, showing that some results from the earlier analysis still hold (for example, cases with higher total family income are more likely to have shared custody), but other differences have lessened (shared-custody cases have become less distinctive as they have become more common). Despite the considerable changes in marriage and divorce patterns over this period, we do not find strong evidence that the changes in custody are related to changes in the characteristics of families experiencing a divorce; rather, changes in custody may be the result of changes in social norms and the process by which custody is determined. 相似文献
