We draw upon data from the Fragile Families and Child Well-Being Study to examine the effect of neighborhood socioeconomic composition on two key economic outcomes, and in doing so to test the validity of the index of concentration at the extremes (ICE) as a measure of neighborhood circumstances. Methodologically, we find that the index succinctly captures economic variation within neighborhoods in a way that avoids problems of colinearity that have characterized prior studies. Neighborhoods can be characterized as falling on a continuum ranging from concentrated disadvantage to concentrated advantage; the ICE measure does a good job capturing this variation and differentiating the neighborhood circumstances experienced by different groups. Substantively, we show that neighborhood economic circumstances are related to new mothers’ welfare use and employment, above and beyond their individual socioeconomic characteristics.  相似文献

Urbanization, rising income inequality, and increasing class segregation have produced a geographic concentration of affluence and poverty throughout the world, creating a radical change in the geographic basis of human society. As the density of poverty rises in the environment of the world’s poor, so will their exposure to crime, disease, violence. and family disruption. Meanwhile the spatial concentration of affluence will enhance the benefits and privileges of the rich. In the twenty-first century the advantages and disadvantages of one’s class position will be compounded and reinforced through ecological mechanisms made possible by the geographic concentration of affluence and poverty, creating a deeply divided and increasingly violent social world.  相似文献

In this article, we use new data from 22 communities to estimate the total flow of dollars back into Mexico as a result of migration to the United States. Our estimates include remittances sent while working abroad and money brought back on return trips; they incorporate transfers by temporary as well as permanent US workers; they include money transferred by legal as well as illegal migrants; and they include funds sent or brought by household heads as well as other family members. We estimate that US$ 24 million in migradollars flowed into the sample communities during the survey year. In some places, the flow of US money equalled or exceeded the value of locally earned income. When generalized to all of Western Mexico, our sample suggests a regional flow of US$ 1.5 billion; and when our data are inserted into an estimation model developed earlier by Lozano Ascencio, we estimate the total flow at US$ 2 billion for Mexico as a whole. Although most of this money was spent on consumption, investments in productive activities were significant, and directly or indirectly, we conclude that migradollars play an extremely important role in Mexican economic production.This article is based on a paper, presented at the University of Chicago, 8 October 1993.  相似文献

Since the 1990s the New Zealand Police have introduced three extensive change management programs to improve the efficiency and effectiveness of their core services; Policing 2000, Policing Excellence and Prevention First. Each program has been fundamentally different, with the more modern programs influencing the way that New Zealand Police deliver services. Policing 2000 evolved from implementation of the first strategic plan, while Policing Excellence and Prevention First were introduced in response to the 2007 fiscal crisis. The programs are compared to identify the differences, and whether these later programs can increase service delivery efficiency and effectiveness.  相似文献

Nonprofit charities and foundations hold endowments and many other kinds of investments. How do these investments perform? Some high‐profile nonprofit endowments, including those of colleges and universities, have been studied previously. This study is the first, to our knowledge, that looks at a large number of the diverse types of nonprofits. We investigate the determinants of investment performance using a large panel data set culled from the 990 forms that nonprofits must file annually with the IRS. In this first part of our article, we discuss our approach and the challenges of using these data to infer investment returns. The IRS data, though less than perfect, yield valuable measures of the investment returns of nonprofits. They reveal that some charities consistently do better in their investment returns than do others.  相似文献

Misguided U.S. policies since 1980 have created a large undocumented population within the United States. Border militarization curtailed circular undocumented migration from Mexico, and Cold War politics precluded the acceptance of refugees from Central America fleeing violence and economic turmoil unleashed by America’s intervention in the region. Although undocumented migration from Mexico has ended, resources devoted to border apprehensions and internal deportations continue to rise, pushing an ever larger number of Central Americans into an immigrant detention system that is ill-equipped to handle them. Although the Trump administration portrays the situation as an immigration crisis, what is really unfolding along the border and within the United States is an unprecedented humanitarian cross that in so many ways is one of our own making.  相似文献

Stereotype threat theory has gained experimental and survey-based support in helping explain the academic underperformance of minority students at selective colleges and universities. Stereotype threat theory states that minority students underperform because of pressures created by negative stereotypes about their racial group. Past survey-based studies, however, are characterized by methodological inefficiencies and potential biases: key theoretical constructs have only been measured using summed indicators and predicted relationships modeled using ordinary least squares. Using the National Longitudinal Survey of Freshman, this study overcomes previous methodological shortcomings by developing a latent construct model of stereotype threat. Theoretical constructs and equations are estimated simultaneously from multiple indicators, yielding a more reliable, valid, and parsimonious test of key propositions. Findings additionally support the view that social stigma can indeed have strong negative effects on the academic performance of pejoratively stereotyped racial-minority group members, not only in laboratory settings, but also in the real world.  相似文献

Abstract

Objective: This study reviews an initiative to educate providers on pediatric cancer survivor care and to establish a cancer survivor registry in a college health center. Participants: Participants were University of Georgia (UGA) college health providers. Methods: Providers attended lectures on survivor care and were encouraged to register on Cancer SurvivorLink. Changes in provider familiarity and practice were measured using baseline and follow-up surveys. A survivor registry was created using health entrance forms and medical records abstraction. Results: Twenty-four providers registered on SurvivorLink, and 16 completed both surveys. Familiarity with survivor care (p = .003) and a survivor health care plan (p = .016) increased. Likelihood to deliver survivor care increased (p = .01). UGA follows 95 survivors; 71 diagnosed at < 21 years. Among survivors diagnosed at < 21 years, 91% reported their diagnosis on entrance forms. Conclusions: Through education and optimization of health informatics, college health centers can identify and provide survivor care to this medically vulnerable population.  相似文献

Homelessness among youths exacerbates an array of challenging life experiences, notable examples of which are pregnancy and parenting. Research is lacking on young men’s attitudes and experiences, and also the influences which homeless youths’ gender identities and sexualities may have on their pregnancy and parenting outcomes and trajectories. This study qualitatively explores gender differentials, including youths’ gender identities and sexual orientations, with regard to their attitudes and experiences of pregnancy and parenting while homeless. Qualitative data were obtained from interviews with a diverse sample of 30 female, male, and transgender homeless youths, ages 18 to 21. Findings revealed that topics of pregnancy and parenting represent a wide range of complexities, different standards, and threats for homeless youths. Although pregnancy is often viewed positively within this community, it is received and experienced differently for each gender and sexuality. Results demonstrate that youths’ unimpeded access to and knowledge of all available reproductive and sexual health care services is essential. These services must be designed and delivered for youths of all gender identities and sexual orientations. Interventions and resources on parenting and co-parenting, particularly models that more inclusively engage a greater diversity of young parents’ involvement, are also urgently needed.  相似文献
