Black feminist writing has alerted us to the interplay of racial and gender identity within the black liberation movement of the 1960s and 1970s. Elaine Brown's A Taste of Power: A Black Woman's Story permits investigation of these interpersonal and intrapsychic dynamics in the instance of the Black Panther Party. Of special interest is the complex role played by masculine introjects in Brown's struggle for individual and collective self-definition. 相似文献

This study investigated how core self‐evaluations relate to work–family (and family–work) conflict and burnout. Drawing from a sample of 289 police officers and civilian staff who were either married or living in a union as common‐law partners, this study advances an empirical integration of work–family and core self‐evaluations research. The results suggested that even when work, nonwork, and demographic variables are controlled for, positive core self‐evaluations (i.e., composite scale, self‐esteem, locus of control, emotional stability) are related to less work–family (and family–work) conflict. The associations between core self‐evaluations and burnout are partially mediated by work–family (and family–work) conflict. Finally, core self‐evaluations moderated the association between work–family conflict and burnout, but not the one between family–work conflict and burnout. 相似文献

The purpose of this qualitative study was to explore the role that friendship, trust, and love played in the courtship and marriages of eleven German heterosexual couples (twenty-two individuals, including three couples of mixed national heritage) who reported their marriages to be happy. A conceptual model is proposed of how the components of friendship, trust, and love (i.e., love experienced as emotion, behavior, and commitment) may form a foundation for happy German marriages. Identified themes inform suggestions for how these findings can be used by educators, practitioners, and clergy to support and strengthen German marriages. 相似文献

In a decentralized supply chain, supplier–buyer negotiations have a dynamic aspect that requires both players to consider the impact of their decisions on future decisions made by their counterpart. The interaction generally couples strongly the price decision of the supplier and the quantity decision of the buyer. We propose a basic model for a repeated supplier–buyer interaction, during several rounds. In each round, the supplier first quotes a price, and the buyer places an order at that price. We find conditions for existence and uniqueness of a well‐behaved subgame‐perfect equilibrium in the dynamic game. When costs are stationary and there are no holding costs, we identify some demand distributions for which these conditions are met, examine the efficiency of the equilibrium, and show that, as the number of rounds increases, the profits of the supply chain increase towards the supply chain optimum. In contrast, when costs vary over time or holding costs are present, the benefit from multi‐period interactions is reduced and after a finite number of time periods, supply chain profits stay constant even when the number of rounds increases. 相似文献

Sick Building Syndrome (SBS) involves seemingly healthy individuals experiencing long-lasting symptoms of physical distress in their work settings and is estimated to exist in 20 to 30% of all work settings in the USA. We examined differences in stress, social support and both physical and psychological symptoms reported by hospital personnel working in known SBS sites in Halifax, Nova Scotia (n = 297) with control employees working in relatively SBS-free settings (n = 228). We found that employees reporting that their health had been affected by the building in which they worked and those complaining of poor air quality were more likely to be found in SBS locations. In addition, those people with higher levels of organizational support and marginally higher levels of union support were also more likely to be found in SBS locations. Further analyses revealed that employees with higher role overload and greater family support, but lower levels of organizational support were more likely to report that their own health had been adversely affected by their place of work. Perceptions of poor air quality were predicted by higher levels of role conflict, role overload, and organizational stress and lower levels of organizational support. These results suggest that SBS may not be solely dependent on environmental factors. 相似文献

Using a forward selection procedure for selecting the best subset of regression variables involves the calculation of critical values (cutoffs) for an F-ratio at each step of a multistep search process. On dropping the restrictive (unrealistic) assumptions used in previous works, the null distribution of the F-ratio depends on unknown regression parameters for the variables already included in the subset. For the case of known σ, by conditioning the F-ratio on the set of regressors included so far and also on the observed (estimated) values of their regression coefficients, we obtain a forward selection procedure whose stepwise type I error does not depend on the unknown (nuisance) parameters. A numerical example with an orthogonal design matrix illustrates the difference between conditional cutoffs, cutoffs for the centralF-distribution, and cutoffs suggested by Pope and Webster. 相似文献

We explore the time series properties of stock returns on the London Stock Exchange around the 1986 market restructuring (Big Bang) and the 1987 stock-market crash using a modified generalized autoregressive conditional heteroscedasticity model. Using this general dynamic model, which allows (a) intradaily returns to have different impacts and persistence on stock-return volatility, (b) return effects on volatility to be asymmetric, and (c) intradaily returns to follow conditional distributions with different fourth moments, we uncover important changes in return dynamics and conditional fourth moments following Big Bang and the 1987 crash not reported before. 相似文献
