We analyze the effects of family capital on child behavior problems in the United States and Great Britain by comparing a longitudinal survey sample of 5- to 13-year-old children from the 1994 National Longitudinal Survey of Youth (N = 3,864) with a similar sample of children from the 1991 National Child Development Study "British Child" (N = 1,430). Findings suggest that in both societies, male children, those with health problems, and those whose mothers are divorced are at increased risk for behavior problems, while those with stronger home environments are at reduced risk. Family structure effects are more pervasive in Great Britain than in the United States, although some of these findings are a function of our racially diverse U.S. sample. We conclude that parents are important in both societies in promoting child social adjustment, and evidence that the more developed welfare state in Great Britain may substitute for capital at home is weak.  相似文献

“Sexuality education”– broadly defined as teaching and learning about a range of issues related to puberty, sexuality, and relationships – occurs all day every day, formally and informally, intentionally and unintentionally. Nevertheless, adults organize policy and instruction for young people around a constrained set of concerns: first, that the sexuality education youth receive does not help them navigate an increasingly sexualized and dangerous world and, second, that the lessons are themselves damaging, exacerbating the risks youth and children already face. I discuss sexuality education’s entanglement with these conventional cultural ideas about youth, sexuality, and education. I consider the ways that abstinence‐only and comprehensive school‐based sexuality education rest on a series of a discursive framings, including a commitment to regulating sexuality and youth, a contemporary “moral panic” that renders all talk about youth and sexuality provocative, and normative and instrumental conceptions of teaching and learning about sexuality. I conclude by discussing the implications of these discursive framings for classroom practice and imagining an alternative model in which sexuality education might embrace ambiguity and ambivalence as a necessary and even welcome condition of young people’s sexuality and education.  相似文献

In the 1990s, the immigrant population in the United States dispersed to non‐traditional settlement locations (what have become known as “new immigrant destinations”). This paper examines whether the allure of new destinations persisted in the 2000s with a particular focus on the internal migration of the foreign‐born during the recent deep recessionary period and its aftermath. Three specific questions motivate the analysis. First, are immigrants, much like the U.S.‐born population, becoming less migratory within the country over time? Second, is immigrant dispersal from traditional gateways via internal migration continuing despite considerable economic contraction in many new destination metropolitan areas? Third, is immigration from aboard a substitute for what appears to be declining immigrant internal migration to new destinations? The findings reveal a close correlation between the declining internal migration propensity of the U.S.‐born and immigrants in the last two decades. We also observe parallels between the geographies of migration of native‐ and foreign‐born populations with both groups moving to similar metropolitan areas in the 1990s. This redistributive association, however, weakened in the subsequent decade as new destination metropolitan areas lost their appeal for both groups, especially immigrants. There is no evidence to suggest that immigration from abroad is substituting for the decline in immigrant redistribution through internal migration to new destinations. Across destination types, the relationship between immigration from abroad and the internal migration of the foreign‐born remained the same during and after the Great Recession as in the period immediately before it.  相似文献

It is widely recognized that urbanization can affect ecological conditions in aquatic systems; numerous studies have identified impervious surface cover as an indicator of urban intensity and as an index of development at the watershed, regional, and national scale. Watershed percent imperviousness, a commonly understood urban metric was used as the basis for a generalized watershed disturbance metric that, when applied in conjunction with weighted percent agriculture and percent grassland, predicted stream biotic conditions based on Ephemeroptera, Plecoptera, and Trichoptera (EPT) richness across a wide range of environmental settings. Data were collected in streams that encompassed a wide range of watershed area (4.4–1,714 km2), precipitation (38–204 cm/yr), and elevation (31–2,024 m) conditions. Nevertheless the simple 3-landcover disturbance metric accounted for 58% of the variability in EPT richness based on the 261 nationwide sites. On the metropolitan area scale, relationship r 2 ranged from 0.04 to 0.74. At disturbance values <15 the EPT rate of decrease was ∼10 times greater than at disturbance values >15. Future work may incorporate watershed management practices within the disturbance metric, further increasing the management applicability of the relation. Such relations developed on a regional or metropolitan area scale are likely to be stronger than geographically generalized models; as found in these EPT richness relations. However, broad spatial models are able to provide much needed understanding in unmonitored areas and provide initial guidance for stream potential.  相似文献

We analyze male occupational attainment using separate models in which occupational level is measured by indigenous socioeconomic index (SEI) scales, indigenous prestige scales, and a common prestige scale. Other than some consistent societal differences, the SEI scales produce highly similar results in both societies. In sharp contrast, both indigenous and common prestige scales indicate a stronger relative effect of origin (compared with education) on occupation in Great Britain. The dimensions of prestige and socioeconomic status thus seem to tap different aspects of the social mobility process, and the societies differ in the transmission of prestige but not socioeconomic status.  相似文献

The riparian zones of urban waterways are frequently degraded by weed invasions. This study examined the effects of different levels of catchment imperviousness, as a surrogate for the extent and intensity of urbanisation, on invasive weeds and soil physical and chemical attributes. The study was conducted adjacent to waterways in the partly urbanised Georges River catchment in south western Sydney. Vegetation and soil sampling was undertaken in the riparian zone of 10 freshwater streams in non-urban (low imperviousness), peri-urban (moderate imperviousness) and urban (high imperviousness) sub-catchments. Soil samples were tested for a suite of physical and chemical properties (moisture, bulk density, organic matter, pH, salinity, phosphorus, potassium and calcium). Increased levels of sub-catchment imperviousness and urbanisation were associated with higher weed coverage and elevated soil geochemical attributes. One of the most interesting findings in this study was that urban soil calcium concentrations were over 2000 times greater than soils collected from non-urban catchments. The BIOENV procedure identified soil pH, salinity, calcium, organic matter, moisture and catchment imperviousness to be important environmental factors associated with variation in riparian vegetation. The single factor of soil pH was most highly correlated with variations in riparian vegetation. Soil pH was approximately 1.5 units higher in urban compared to non-urban riparian soils. We speculate that there is a link between urban concrete materials, urban soil and water contaminants and riparian weed invasion. We also recommend further study into the contribution of urban concrete materials on the geochemical contamination of riparian soils.  相似文献

The Renewal of Population Loss in the Nonmetropolitan Great Plains   总被引:1,自引:0,他引:1  
Abstract An analysis of population trends in 293 nonmetropolitan Great Plains counties from 1950 to 1990 reveals that the population turnaround of the 1970s has indeed ended. During the 1980s, 84 percent of these nonmetropolitan counties had total population declines, a proportion greater than any other decade studied. A majority of counties had natural population increase, but such increases were offset by net outmigration as 96 percent of the counties had such losses during the 1980s. The influence of the independent variables on population change shifted from decade to decade. The most important variable in producing positive population trends was the ability of the county to attract retirement migrants.  相似文献

We examined associations of fish assemblages and fish traits with urbanization and selected environmental variables in nine major United States metropolitan areas. The strongest relations between fishes and urbanization occurred in the metropolitan areas of Atlanta, Georgia; Birmingham, Alabama; Boston, Massachusetts; and Portland, Oregon. In these areas, environmental variables with strong associations (rs ≥ 0.70) with fish assemblages and fish traits tended to have strong associations with urbanization. Relations of urbanization with fish assemblages and fish traits were weaker in Denver, Colorado; Dallas-Fort Worth, Texas; Milwaukee-Green Bay, Wisconsin; and Raleigh, North Carolina. Environmental variables associated with fishes varied among the metropolitan areas. The metropolitan areas with poor relations may have had a limited range of possible response because of previous landscape disturbances. Given the complexities of urban landscapes in different metropolitan areas, our results indicate that caution is warranted when generalizing about biological responses to urbanization.  相似文献

The impacts of employment in the coal industry remain controversial. Few studies have investigated these impacts over the decade of the great recession and in light of the nation's changing energy economy. We bring together two long‐standing rural sociological traditions to address debates framed at the national level and for Appalachian communities facing the throes of transition from the coal industry. Building from rural sociology's “poverty and place” tradition and from natural resources sociology, we examine the relationship between coal employment and communities’ economic well‐being as indicated by poverty, household income, and unemployment. The study spans U.S. and Appalachian counties from 1990 to 2010. U.S. counties with greater coal employment in 1990 had lower income and higher poverty in 2000. Overall, however, coal employment's effect is mixed in the 1990–2000 decade. By contrast, for the recent 2000–2010 decade, coal employment is positively associated with indicators of well‐being. In Appalachia, fewer employment alternatives outside mining are related to higher well‐being. Our findings extend the poverty and place literature and the natural resources literature and underscore why a just transition away from coal should focus on moving communities toward sectors offering better future livelihoods.  相似文献

This paper focuses on 30 couples who received a pension and other services from two private trusts in Detroit, Michigan beginning in 1929 or 1930. Results of the qualitative analysis of case files, which contain notes recorded chronologically for 17 of the couples and then surviving spouses, provide a portrait of older couples' lives prior to a partner's death, circumstances surrounding the death, and changes in the social support systems of widows and widowers until their deaths. Close examination of the experiences of these couples is a reminder of how old age and widowhood were experienced prior to the enactment of public pensions and health insurance in the United States.  相似文献

The Great Recession produced the highest rates of unemployment and foreclosure in the United States since the Great Depression. In this article the author examines the consequences of these poor economic conditions for fertility in the United States by estimating the effect of area‐level economic conditions on state fertility in the years leading up to and including the Great Recession. The economic impacts of the Great Recession, captured by state‐level economic conditions, had a strong negative effect on fertility in models with state and year fixed effects. These reductions in fertility were likely caused both by increased economic hardship and increased economic uncertainty.  相似文献

Understanding the impact of urbanization on terrestrial biogeochemistry is critical for addressing society’s grand challenge of global environmental change. We used field observations and remotely sensed data to quantify the effects of urbanization on vegetation and soils across a 100-km urbanization gradient extending from Boston to Harvard Forest and Worcester, MA. At the field-plot scale, the normalized difference vegetation index (NDVI) was positively correlated with aboveground biomass (AGB) and foliar nitrogen (N) content and negatively correlated with impervious surface fraction. Unlike previous studies, we found no significant relationship between NDVI or impervious surface area (ISA) fraction and foliar N concentration. Patterns in foliar N appeared to be driven more strongly by changes in species composition rather than phenotypic plasticity across the urbanization gradient. For forest and non-residential development, soil nitrogen content increased with urban intensity. In contrast, residential land had consistently high soil N content across the gradient of urbanization. When field observations were scaled-up to the Boston Metropolitan Statistical Area (MSA), we found that soil and vegetation N content were negatively correlated with ISA fraction, an indicator of urban intensity. Our results demonstrated the importance of accounting for the influence of impervious surfaces when scaling field data across urban ecosystems. The combination of field data with remote sensing holds promise for disentangling the complex interactions that drive biogeochemical cycling in urbanizing landscapes. Empirical data that accurately characterize variations in urban biogeochemistry are critical to gain a mechanistic understanding of urban ecosystem function and to guide policy makers and planners in developing ecologically sensitive development strategies.  相似文献

Comparisons between the United States and Great Britain reveal many similarities in broad‐based religious concerns and values. Nonetheless, surveys over the last 40 years document a widening gap between the two countries in individual‐level religious commitment. This article suggests that the residual effect of prior marginalization of certain groups and the way they responded to the crucible of marginality is a critical variable to consider. The structure of the religious market in Great Britain kept peripheral groups from turning to religion for support or encouragement in their resistance to the establishment; this, however, was not the case in the religious economy of the United States. Using data collected in the most recent wave of the World Values Survey, I show that higher levels of religious commitment among particular groups with a history of marginalized status—namely African Americans and Southerners—in the United States and the lack of similar levels among similar groups in the British context—ethnic minorities and residents of Scotland and Wales—explain part of the gap in religious commitment between the two countries.  相似文献

Forest bird communities across a gradient of urban development   总被引:1,自引:1,他引:0  
This study examined native bird communities in forest patches across a gradient of urbanization. We used field data and multivariate statistical techniques to examine the effects of landscape context, roads, traffic noise, and vegetation characteristics on bird community composition in the North Carolina Piedmont (U.S.A.). Landscape-level variables, particularly those related to urbanization, were most important in structuring forest bird communities. Specifically, we found that road density and amount of urban land cover were the best predictors of species composition. We found that urban and rural bird communities were quite distinct from each other. Rural communities had more long-distance migrants and forest interior species but species richness did not differ between the communities. Our results suggest some specific guidelines to target bird species of interest both inside and outside of urban areas. For example, if increasing numbers of migratory species is of primary concern, then conservation areas should be located outside of urban boundaries or in areas with low road density. However, if maximizing species richness is the focus, location of the conservation area may not be as important if the conservation area is surrounded by at least 50 m of forest habitat in all directions.  相似文献

In 2014, police responses to protests and riots in Ferguson, Missouri, prompted an unprecedented level of news coverage on the phenomenon of police militarization. Though the increased attention to police militarization and governmental programs thought to facilitate it (e.g., the 1033 Program) may give the impression that police militarization is a recent phenomena, social scientists have been documenting trends in police militarization for decades. This article provides an overview of the social science research literature on police militarization, starting with a discussion of a theory informed conceptualization of police militarization. We next discuss the major normative debates that have guided research on police militarization. We then review the empirical literature that focuses on the methodological approaches and findings of extant work on police militarization. Finally, we close with an overview of the state of the literature and suggestions for future research. Our major suggestion for future work is to consider the dimensions of police work that police militarization can occur in while continuing to engage with the normative debates of previous scholars so as to improve the overall quality of police work and public safety in the United States.  相似文献

Despite drastic changes in the American family, a significant minority of Americans marry early. Using data from the National Longitudinal Study of Adolescent Health (N= 14,165), this study evaluates the prevalence and antecedents of early marriage in the United States. The results indicate 25% of women and 16% of men marry before age 23, and early marriage varies widely across a number of characteristics. Individuals who marry earlier are more likely to be from disadvantaged families, from conservative Protestant or Mormon families, to value their religious faith more highly, to have a high‐school diploma but a lower educational trajectory, and to cohabit before marriage. Scholars and policymakers interested in marriage should pay adequate attention to understanding and supporting these individuals’ marriages.  相似文献
