Using data from the 1996 General Social Survey and the 1973 Chicago Crowding Study, we test the hypotheses that African Americans feel and express more anger than whites, that sense of control (versus powerlessness) lessens anger and mistrust increases anger, and that these indicators of alienation affect anger differently for African Americans and whites. We find that when age and gender are controlled, African Americans neither feel nor express more anger than whites, despite having a lower average sense of control and higher mistrust. This is partly because the effects of sense of control and mistrust on anger differ by race. Sense of control reduces feelings of anger and anger expression more for African Americans than whites. Mistrust increases feelings of anger for whites, but not African Americans. The results provide further evidence that, in the stress process, social structural location may moderate the effects of "detriments" and "resources" on emotional upset.  相似文献

Urbanisation is a growing global phenomenon having multiple ecological consequences. However, the effects of urbanisation on biodiversity remain ambiguous, and some evidence exists that cities provide valuable secondary habitats for many species, possibly mitigating regional biodiversity loss. Therefore, the value of urban sites for biodiversity depends on local habitat conditions and the configuration of the surrounding landscape. We aimed to disentangle the effects of local habitat parameters (management, plant diversity) and urban matrix variables (urbanisation, isolation) on carabid beetle and spider diversity and traits in informal urban green spaces in Berlin, Germany. Habitat management and isolation were the most important influences on carabid beetle and spider species and trait compositions. Spider communities of irregular managed sites contained 2.5 times more species of conservation concern than extensive (regular) managed sites. Moreover, irregular managed sites contained larger species (both for carabid beetles and spiders) and affected the hunting mode of spiders. Isolated sites tended to have lower spider species richness and number of spider species of conservation concern. Moreover, isolated sites were characterised by small, mobile and herbivorous carabid beetles. In contrast, urbanisation and local plant diversity had no effect on carabid beetles and spiders. We conclude that urban grasslands within residential areas – even if not targeted for conservation plans – can provide important habitats for conserving biodiversity, including species of conservation concern. Reducing the intensity of habitat management and increasing the connectivity of urban grassland sites can promote diverse arthropod communities and should therefore be considered in urban planning.  相似文献

This paper examines CEO compensation, with an emphasis on the power of CEOs to influence their own compensation by managing the compensation process. It analyzes the CEO's power over the board of directors and the political tactics used by the CEO to manage the board and its compensation decisions. An empirical examination of CEO compensation in 203 large American manufacturing firms in 1985 illustrates the effect of CEO power on compensation and the flexibility available to the CEO in establishing the legitimacy of compensation. The implications of this perspective for management control of corporations and for CEO compensation research are considered.  相似文献

We analyze factors explaining differences in hierarchical authority between men and women within and across categories of race and ethnicity in two time periods, finding that the processes leading to authority within the workplace operate differently by gender than by race or ethnicity. The demand-side factor, percentage of women in an occupation, helps explain authority differences between men and women in most groups. Supply-side factors, and, in white–black comparisons, occupational location, contribute to differences by race and ethnicity within genders. In the later period, education is particularly important for Hispanic men reflecting, we believe, the recent surge in immigration rates.  相似文献

Abstract

An assessment of the prevalence and scope of nutrition services offered through 208 randomly selected American College Health Association member student health centers revealed that 79% of the 160 respondents provided some type of nutrition education for students. One-to-one counseling, available at 96% of the institutions, was the most common approach. The larger the school's enrollment, the more likely it was to provide programs in nutrition. All of the institutions with student populations of more than 35,000 offered some type of nutrition service, as did 52% of the 19 schools with enrollments between 2,000 and 5,000. Health educators, nurses, doctors, dietitians, and trained peer educators provided the services, with registered dietitians the most common providers and often coordinators of the programs. Costs to students for nutrition interventions were nominal; weightmanagement programs were the most expensive and showed the greatest variation in content.  相似文献

The impact of divorce on children has been well documented over the past 30 years. Divorcing parents who are also experiencing clinical depression often have a compromised ability to parent well and to give the children needed support. Children are then impacted both by the divorce itself and the effects of parental depression. They are at higher risk of numerous problems including poorer physical health, deficits in academic performance not attributable to intellectual limitations, poor social functioning, conduct disorder and other disruptive behavior problems, phobias, and other anxiety disorders. Because children of depressed parents are at higher risk for depression themselves, they should be monitored for depressive symptoms. If there are concerns, the child should be assessed by a mental health professional.  相似文献

To explore sexually exploited youths' perspectives of how street outreach workers can effectively provide outreach and connections to services, we conducted qualitative interviews with 13 female participants, ages 14 to 22, in a Midwest U.S. city. Participants reported multiple types of exploitation, most first exploited by age 13, plus substance use and recurrent homelessness. Nearly all had a pimp, and all used the internet as a venue for sexual exploitation. Participants wanted outreach workers to use “soft words” to refer to exploitation. They expressed contradictory images of their “boyfriend” pimps and their exploitation. They wanted outreach workers to “provide resources,” “be nonjudgmental,” “listen,” and “care.” Street outreach can be one way to support sexually exploited youth but should occur in multiple settings.  相似文献

Increasing numbers of states are in the process of passing laws requiring all new parents to receive educational materials to prevent shaken baby syndrome (SBS). These laws create powerful opportunities to reach large numbers of families with an important prevention effort. Results from the effort to raise SBS awareness described here indicate that not only is the content of SBS prevention (e.g., consequences of shaking; emotion regulation/coping skills; safety planning) an important consideration; so too is the approach any given prevention program utilizes. By incorporating social work theory on family-centered practice, social workers, home visitors, and other prevention professionals strengthen the likelihood of having a meaningful impact on caregivers' safe strategies for coping with the frustrations of caring for an infant.  相似文献
