We evaluate the relationship between job proximity and male joblessness at the neighborhood level in Cleveland and Milwaukee. Using two tract-level measures of proximity to employment (i.e., physical distance and commute time), we find mixed evidence for the spatial mismatch hypothesis. As expected, we find that predominantly black neighborhoods in both cities have higher rates of male joblessness. However, contrary to the spatial mismatch hypothesis, we find that these neighborhoods are also physically closer to low-skill jobs than are predominantly white neighborhoods. In addition, predominantly black neighborhoods have higher average commute times, suggesting that spatial isolation from employment may be better characterized along a temporal rather than a physical dimension.  相似文献

Prior to the late 1990s, Ecuadorian international migration was directed primarily toward the United States. Of the estimated 400,000 Ecuadorians living in the United States, most are concentrated in metropolitan New York and many hail from the south–central highlands of Cañar and Azuay Provinces. In the mid– to late–1990s, Ecuador entered a political and economic crisis just as clandestine transportation to the United States became increasingly expensive and dangerous. Within two years Ecuadorian migration diversified radically and a "new emigration" formed. Many thousands of Ecuadorians from throughout the country migrated to Europe, mostly Spain, but also to France, Italy, and The Netherlands. Prior to 1998, few Ecuadorians lived in Europe, but now, Ecuadorians are the largest immigrant group in Madrid and one of the largest in Spain. The migrant stream was led by women and composed of people from a variety of ethnic and socioeconomic backgrounds. Ecuadorians find themselves working in a variety of services (especially women) and negotiating a volatile, even hostile, social, and political environment.
This "new emigration" has numerous implications for Ecuadorian families, the economy, and the nation–state. Understanding the implications requires a comparative approach that examines at least three aspects of the new emigration: the role of gender, the importance of transnational ties and connections, and the emerging roles of state and non–state actors in the formalization of migration.  相似文献

Previous scholarly research on selection bias in news about murder indicates that race and gender stereotypes and, to a much lesser extent, the relative frequency of particular murders explain why some homicides are made into news and others are not. However, previous research has directed nearly exclusive attention to white newspapers. The present research remedies this omission by directing attention to the factors that shape selection bias in news about murder in a big-city African American newspaper. The results indicate that the relative frequency dimension of newsworthiness is a weak and inconsistent explanation of selection bias in news about murder in the black newspaper examined. Race, however, has profoundly different effects in white and African American newspapers. Whereas white newspapers use long-standing race stereotypes to filter news about murder, the data from the African American newspaper signal a firm rejection of the black image in the white mind (Entman and Rojecki 2000). Newspaper images of women and men are another matter. In both black and white newspapers, gender stereotypes uniformly filter news about murder and fundamentally distort gender effects. The implications of these findings are discussed including the clear need and ample scholarly room for replicative analyses of news about murder in other African American newspapers, with a keen eye on both "raced ways of seeing" (Hunt 1999, pp. 181–215) and gendered ways of seeing.  相似文献

To ascertain the need for and to inform development of guidelines for voting in long-term care settings, we conducted a telephone survey of Philadelphia nursing (n = 31) and assisted living (n = 20) settings following the 2003 election. Substantial variability existed in procedures used for registration and voting, in staff attitudes, and in the estimated proportion of residents who voted (29%+/-28, range 0-100%). Residents who wanted to vote were unable to do so at nearly one-third of sites, largely due to procedural problems. Nearly two-thirds of facilities indicated they assessed residents' voting capacity before the election. However, methods differed and may have disenfranchised residents who were actually competent to vote. Current procedures in many facilities fail to protect voting rights. These data suggest that rights might be better protected if election officials took charge of registration, filing absentee ballot requests, ballot completion, and trained LTC facility staff on voters' rights and reasonable accommodations.  相似文献

The present brief report followed children exposed to consequences for violating Purchase, Use, and Possession (PUP) laws over time to assess changes in their smoking status. Youth in 24 towns were surveyed once a year for 3 years, and rates of tobacco use for those fined for PUP law violations were assessed. Of those who were given a ticket for a PUP law violation, 35 (39%) reported not smoking during year 1. Students in grade 7 were more likely to have quit smoking (84%) than those in grade 8 (35%), grade 9 (32%), or grade 10 (21%). For the two follow-up years, 45% and 41% reported not smoking. Assuming those who attrited were smokers, it is possible that about 15% to 24% of the original sample of children cited actually quit smoking over the follow-up period. The implications of these findings are discussed.  相似文献

Although incarceration rates have risen sharply since the 1970s, medical sociology has largely neglected the health effects of imprisonment. Incarceration might have powerful effects on health, especially if it instills stigma, and it could provide sociologists with another mechanism for understanding health disparities. This study identifies some of incarceration's direct and indirect effects and rigorously tests them using the National Longitudinal Survey of Youth. It finds that incarceration has powerful effects on health, but only after release. A history of incarceration strongly increases the likelihood of severe health limitations. Furthermore, any contact with prison is generally more important than the amount of contact, a finding consistent with a stigma-based interpretation. Although this relationship is partly attributable to diminished wage growth and marital instability, the bulk of the effect remains even under the most stringent of specifications, including controls for intelligence and the use of fixed effects, suggesting a far-reaching process with a proliferation of risk factors. The study also finds that incarceration contributes only modestly to racial disparities, that there are few synergistic interactions between incarceration and other features of inequality, including schooling, and that the evidence for a causal effect is much weaker among persistent recidivists and those serving exceptionally long sentences. These study findings are inconsistent with recent speculation; nevertheless, incarceration is an important addition to sociology's research agenda. Exploring incarceration could lead to, among other things, a fruitful synergy among studies on fundamental causes, stigma, and stress.  相似文献

OBJECTIVE: Prior research shows that college athletes have higher rates of substance use, especially alcohol, than do college students who are not involved in athletics. To augment the literature, the author sought to determine which sports/teams are at the greatest risk for substance use. PARTICIPANTS: The author used data from the 1999 Harvard School of Public Health College Alcohol Study, a national survey of college and university students in the United States. METHODS: A series of chi-square and logistic regression models examined variation in substance use among college athletes on the basis of sport/team affiliation. RESULTS: Findings indicated that male hockey and female soccer athletes were the most likely to report substance use and that male basketball and cross-country/track athletes reported lower levels of substance use. CONCLUSION: There is variation in substance use on the basis of sport/team affiliation, and future researchers should examine why certain groups of athletes have higher rates of substance use.  相似文献

Locational Decisions of Charter Schools: Probing the Market Metaphor   总被引:4,自引:0,他引:4  
Objective . Debate about market–oriented school–choice proposals often centers on questions of whether they will help or hurt minorities and the poor. We examine the locational decisions of different types of charter schools in the District of Columbia (D.C.) to assess their distributional consequences. Methods . We employ ordered probit regression to estimate models of the degree to which census tracts are served by charters. Results . Charters are more likely to locate in areas with high proportions of African–American and Hispanic residents than in the predominantly white neighborhoods, and more likely to locate in neighborhoods with middle incomes and high home ownership than in either poor or wealthy areas of the city. This is especially true of those operated by for–profits and those chartered by the elected rather than appointed chartering body. Additionally, we observe charters taking political and practical considerations into account when deciding where to locate. Conclusions . Proponents claim that charter schools will locate where need is greatest, while critics fear they will shy away from neighborhoods housing disadvantaged and minority students. We find that both camps are oversimplifying. Locational patterns are more complex and appear to be sensitive to variations in the type of charter school as well as the institutional characteristics of the chartering agency. Although market incentives are important, so too are pragmatic factors and institutional context.  相似文献
