This paper calls on schools of social work to provide more workers for practice in rural settings. It reviews the basic character of rural areas and the need for systematic intervention and program development to alter the disproportionate amount of social and economic problems existing there. The use of rural settings for student practice is reviewed, including concepts such as the community of communities, models for designing practice experiences, the role of the educator, and positive features and barriers found in providing social services.  相似文献

Student veterans may experience challenges as they transition from military to student life, including adjusting to the academic environment, coping with mental health concerns, and redefining their identities. Research indicates that veterans may have difficulty finding meaning and purpose outside of the military (Brenner et al., 2008; Doenges, 2011). This study explored variables that may affect meaning and purpose in student veterans' lives, specifically negative career thoughts and depression. One hundred thirty-two student veterans at U.S. institutions were surveyed. The results revealed that both negative career thoughts and depression were statistically significant predictors (p < .001) of the presence of meaning in life, with 46% of the variance in the presence of meaning in life scores accounted for by participants' negative career thinking and depression levels. Pearson correlations indicated that all variables were statistically significant (p < .01). Future research could explore how other career readiness and self-assessment constructs are related to meaning and purpose in student veterans' lives, as well as the intersection of mental health and career factors. Interventions that focus both on the presence of negative career thoughts and depressive symptomatology may positively influence student veterans' report of meaning and purpose in life.  相似文献

Current family policy suggests that in order to restore family values we, as a society, need to focus on reviving a child-centered household. Full-time mothering is lauded as an honorable choice that will advance this goal and ultimately strengthen traditional family values. However, current welfare policy is contrary to this notion in that mandatory welfare-to-work programs deny women receiving public assistance the choice to be full-time mothers. Based on in-depth interviews with female welfare recipients in four rural Appalachian counties, this paper evaluates the problems women face as they confront the difficult choices of being either a “good mother” or a “good recipient.” From a feminist perspective, findings suggest that welfare reform programs in rural communities have put poor women in a proverbial “catch-22” with regard to effective parenting. Although many of the women strive to be ideal mothers as defined by societal standards, they often find that they cannot carry out the role effectively because of welfare reform regulations.  相似文献

Abstract Studies of reactions to nuclear facilities have found consistent male/female differences, but the underlying reasons have never been well‐clarified. The most common expectations involve traditional roles—with men focusing more on economic concerns and with women (especially mothers) being more concerned about family safety/health. Still, with changing gender roles, women are becoming economic providers as well as caregivers; past studies have not actually examined the interaction of employment and gender effects. This study examines a rural county where issues of risk and economic interest were both salient—a county where a nuclear waste site had been proposed but where an existing nuclear power plant was a major employer. Overall, concern levels expressed by employed mothers did not differ significantly from those in the rest of the sample, but further analyses revealed a sharp contrast: In the half of the county that was home to the existing nuclear power plant, where economic concerns could be expected to be more salient, over 90 percent of the employed mothers expressed low levels of concern; in the other half of the county, closer to the potential risks of the proposed nuclear waste site, almost 90 percent of the employed mothers expressed high levels of concern. No such differences are found for other sociodemographic groups. This county may or may not be unique; what the findings show is that the interplay of geography, gender roles and risks should receive more attention in other contexts, as well.  相似文献

In estimating the eigenvalues of the covariance matrix of a multivariate normal population, the usual estimates are the eigenvalues of the sample covariance matrix. It is well known that these estimates are biased. This paper investigates obtaining improved eigenvalue estimates through improved estimates of the characteristic polynomial, which is a function of the sample eigenvalues. A numerical study investigates the improvements evaluated under both a square error and an entropy loss function.  相似文献
