This study focuses on differences in sense of belonging between lesbian, gay, and bisexual (LGB) and heterosexual students. Data from 1,745 secondary school students were collected with an online survey. Step-wise multiple regression analyses was used to investigate the relationship between sexual orientation and sense of school belonging. The results show that sexual orientation has an impact on sense of belonging for girls, but not for boys. Perceived discrimination and LGB friendliness of the school appeared to be important indicators of sense of belonging for all the respondents, irrespective of their sexual orientation.  相似文献

Connections to the sea often define the character of coastal towns. However, as migrants arrive and economic diversification occurs, views about the use of marine resources and the ocean environment can change. Using survey data from Maine, we examined whether shifting demographics affect public perceptions of marine resource uses and coastal environmental concerns. We tested resource use and environmental items against a common set of demographic, background, and place-related variables. Results indicate that the level of education and the county of residence predict Mainers?? views about different marine resource uses and ocean-related environmental issues. Political party affiliation strongly influences environmental concern but not views about the use of marine resources. Migration history, on the other hand, has little effect. Understanding community contexts as well as individual background and ideological orientations will be critical as managers attempt to balance alternative uses of marine resources and resolve coastal environmental problems.  相似文献

This study uses data from the 2002 Rwandan census to situate the discourse on migration and orphan well-being within the context of the household. According to its findings, migrant orphans are less likely than non-migrant orphans to live in households with less favorable structural characteristics such as single-parent households. Significant differences are also found in the implied gains to living standards and schooling associated with migration among paternal, maternal, and double-orphans. However, the higher living standards and schooling attainment of orphan migrants relative to their non-migrant counterparts disappear within child-headed household contexts. More generally, the results indicate that the higher living standards of migrant orphans are in part driven by the fact that they mostly live in households with migrant household-heads or migrant spouses. Yet the analysis also suggests that orphans living within these contexts experience higher levels of intra-household discrimination in investments in their schooling, relative to their orphan counterparts who live in non-migrant households.  相似文献

Population momentum is the main driver of global population growth today, and this makes an appreciation of momentum critical to understanding contemporary worldwide growth dynamics. This article traces population momentum along with two recently defined measures of momentum decomposed—stable and nonstable momentum—across the demographic transition. We use historical data and population projections from 16 countries to illustrate some previously ignored empirical regularities of the demographic transition in both the developed and the developing world. We also demonstrate the dynamic nature of stable and nonstable momentum, as changes in stable momentum lead to predictable changes in current and future nonstable momentum. These results suggest that momentum, which by definition is measured at a point in time, can also be considered as a process that unfolds over time.  相似文献

In this article an attempt is made to assess the major health problems of the second half of the twentieth century in developed countries, the methods appropriate to these problems, and the pattern of medical services necessary to deal with them. From an examination of mortality and morbidity trends it is suggested that the most important problems are likely to be the mortality, malformation and disability established before birth, mental illness, and the disease and disability associated with ageing. Reasons are given for doubting whether control of breeding, the method which has contributed greatly to the improvement of plants and other animals, can be expected to be effective in the case of man, and hence reliance must continue to be placed on modifications of the environment to which achievement hitherto has been entirely due. The methods likely to be significant are: an extension of measures already in use for control ofthe physical environment; discovery and application of knowledge concerning the social environment; and elaboration of more effective methods of preventing and treating disease in the individual. Profound changes will be needed in the pattern of services through which medical knowledge is applied, the most important being unification ofthe major classes ofhospitals - acute, mental and chronic; association ofthe preventive personal health services with curative services (rather than with environmental services); and the strengthening of domiciliary medical care, particularly through a new and more intimate relationship between general practitioner and hospital services.  相似文献

Brass' relational model is based on a linear relationship between the logits of the cumulative probability of dying before age x in a standard mortality distribution and those observed in any population. In this study the appropriate way to estimate the linear parameters associated with Brass' model is clarified. Five methods are presented to estimate the coefficients associated with Brass' relational model. Each method is applied to simulated data to examine the efficiencies of each model in mortality estimation.  相似文献

The assessment of the impact that socioeconomic determinants have on the prevalence of certain chronic conditions reported by respondents in population surveys must confront two problems. First, the self-reports could be in error (false positives and false negatives). Second, those reporting are a selected sample of those who ever experience the problem, and this selection is heavily influenced by excess mortality attributable to the condition being reported. In this article, we use a combination of empirical data and microsimulation to (a) assess the magnitude of the bias attributable to the selection problem, and (b) suggest an adjustment procedure that corrects for this bias. We find that the proposed adjustment procedure considerably reduces the bias arising from differential mortality.  相似文献

This study examines how familial contexts affect poverty disparities between the children of immigrant and U.S.-born blacks, and among black and nonblack children of immigrants. Despite lower gross child poverty rates in immigrant than in U.S.-born black families, accounting for differences in family structure reveals that child poverty risks among blacks are highest in single-parent black immigrant families. In addition, within two-parent immigrant families, child poverty declines associated with increasing assimilation are greater than the respective declines in single-parent families. The heads of black immigrant households have more schooling than those of native-black households. However, increased schooling has a weaker negative association with child poverty among the former than among the latter. In terms of racial disparities among the children of immigrants, poverty rates are higher among black than nonblack children. This black disadvantage is, however, driven by the outcomes of first-generation children of African and Hispanic-black immigrants. The results also show that although children in refugee families face elevated poverty risks, these risks are higher among black than among nonblack children of refugees. In addition, the poverty-reducing impact associated with having an English-proficient household head is about three times lower among black children of immigrants than among non-Hispanic white children of immigrants.  相似文献

Two waves of a Social Security Beneficiary survey were analyzed to consider differences in the retirement resources of women and men based on marital status and race/ethnicity. Despite increased workforce participation the economic situation of single women, including white women, worsened over time. A bifurcation in retirement resources was found, with men relying more on private income sources and women depending more on Social Security. Current retirement policies based on privatization will continue to adversely impact women who work at low-paying jobs, receive lower wages, and live longer than men.  相似文献
