Abstract Underemployment, which goes beyond unemployment to include the working poor, discouraged workers, and involuntary part-time workers, is a useful measure of employment hardship. We argue that underemployment should be included with other conventional indicators of the disadvantaged circumstances of nonmetropolitan (nonmetro) labor, in terms not only of prevalence, but also of the likelihood of transitions into and out of underemployment. We take advantage of the quasi-longitudinal nature of the U.S. Current Population Surveys to estimate models of year-to-year employment transitions for the quarter century 1968 to 1993. We find that (1) adequately employed nonmetro workers are more likely than their more urban counterparts to become underemployed; (2) the nonmetro underemployed are less likely to become adequately employed; (3) statistical controls only strengthen these nonmetro disadvantages; (4) the employment transitions of nonmetro workers are less affected by shifts in the direction of the national economy than are those of metro workers; and (5) nonmetro women are more disadvantaged than women residing elsewhere.  相似文献

Taking out student loans to assist with the costs of postsecondary schooling in the US has become the norm in recent decades. The debt burden young adults acquire during the higher education process, however, is increasingly stratified with black young adults holding greater debt burden than whites. Using data from the NLSY 1997 cohort, we examine racial differences in student loan debt acquisition and parental net wealth as a predictor contributing to this growing divide. We have four main results. First, confirming prior research, black young adults have substantially more debt than their white counterparts. Second, we find that this difference is partially explained by differences in wealth, family background, postsecondary educational differences, and family contributions to college. Third, young adults’ net worth explain a portion of the black–white disparity in debt, suggesting that both differences in accumulation of debt and ability to repay debt in young adulthood explain racial disparities in debt. Fourth, the black–white disparity in debt is greatest at the highest levels of parents’ net worth. Our findings show that while social and economic experiences can help explain racial disparities in debt, the situation is more precarious for black youth, who are not protected by their parents’ wealth. This suggests that the increasing costs of higher education and corresponding rise in student loan debt are creating a new form of stratification for recent cohorts of young adults, and that student loan debt may be a new mechanism by which racial economic disparities are inherited across generations.  相似文献

Objective: To pilot test the feasibility of implementing an elder abuse (EA) screening tool (DETECT) designed for medics.

Methods: Testing occurred between September 17th, 2015 and October 26th, 2015. MedStar Mobile Healthcare medics completed the DETECT tool when responding to calls for community-dwelling patients 65 years of age or older.

Results: The DETECT tool was used 1,248 times by 97% of medics responding to an eligible 911 call. Medics responded affirmatively to at least one screening item on 209 of the completed screenings (16.8%). Immediately following the introduction of the DETECT tool, there was an increase of 5.4 (226% above baseline) reports per month (p = 0.0056).

Conclusions: The DETECT tool was easily incorporated into medic’s field-based practice and resulted in an increase in medic generated reports of EA to APS. Future research designed to evaluate the tool’s validity and reliability are warranted.  相似文献

Based on prior literature, this article offers a reconciliation of the core roles of nonprofit boards and aligns these role‐sets with organizational theories. A survey instrument was developed and validated to measure each of four role‐sets (monitoring, supporting, partnering, and representing) to assess whether emphasis on specific roles affects board members’ perception of performance. Our study of nonprofit boards in a midsized midwestern city found that balance across the role‐sets was associated with effective organizational performance. Furthermore, when board members describe any of the four role‐sets as deficient, they perceive the organization as less effective. The results of the study provide practitioners with a validated survey tool that provides nonprofit boards with a method to identify which roles their board emphasizes.  相似文献

A gap exists between empirical evidence demonstrating the risks posed by domestic violence (DV) and the weight that evidence is given by custody evaluators. This gap may result from common beliefs about DV that diminish or deny its seriousness, which include that mothers often make false allegations to gain advantage and that DV and high conflict are synonymous and do not require differential approaches. Using a multiple segment factorial vignette design, we systematically assessed how these beliefs influenced custody evaluators' (N = 603) recommendations and judgments of the believability of allegations. Mother's demeanor (i.e., hostile vs. pleasant) was the most consistent predictor of evaluators' recommendations and judgments of credibility. Findings have implications for providing research-based education and training for evaluators.  相似文献

This paper outlines the current knowledge base for men's experiences of studying social work in the UK. Given the relatively limited knowledge of these experiences, this paper also examines the findings from other literatures in order to inform this study, including nursing and primary school teaching educational literature. Men progress more poorly than women in social work, nursing and primary school teaching courses, and in other countries in addition to England. This paper also explores the educational experience of men in education and higher education more generally. The findings of a regression analysis are presented here. This analysis was conducted with secondary data from the GSCC of student progression on undergraduate and postgraduate social work courses in England between 2006 and 2011. Some potential reasons for these progression issues are identified from the related literatures and from the wider educational literature. Also indicated are some areas for further study to support a more diverse, representational profession and workforce.  相似文献

Compared with older adults with disabilities and those who autonomously choose to live in squalor, self-neglect syndrome arises from a predicate state of vulnerability in frail older adults. This state of vulnerability is characteristically associated with a decline in decision-making capacity regarding the ability to care for and protect oneself. We developed the COMP Screen to evaluate vulnerable older adults to identify potential gaps in decision-making capacity using a screening tool. A total of 182 older adults were evaluated and consistent declines in cognitive ability and decision-making processes were present in this population. However, there were no significant differences between elders referred for self-neglect and matched older adults. These findings suggest that declines in decision-making processes are not uncommon in vulnerable older adults but traditional conceptualizations of decision-making capacity may be inadequate for differentiating the capacity for self-care and protection in elders who self-neglect.  相似文献

Residential lawns provide chronosequences to examine influences of home age and aboveground tree biomass (ATB) on soil carbon (C) levels. Soil C dynamics were compared between 44 lawns with trees (LwT) and 23 without trees (PL). At the 0–15 cm depth, LwT had higher mean soil C than PL and an earlier rise in median soil C across home age. Nonparametric quantile regression also showed a steeper rise in the 5th, 50th, and 95th soil C quantiles for LwT. Fitted polynomial regression models indicated that home age and ATB together accounted for 40 % of the soil C variation at the 0–15 cm depth [C = 1.34 + 0.05(Age) + 0.0003(ATB)]. At the 15–30 cm depth, the interaction between home age and ATB explained 33 % of the soil C variation [C = 0.78 + 0.0003(Age*ATB)]; at 30–50 cm, ATB was responsible for 20 % [C = 0.56 + 0.0003(ATB)].  相似文献
