The authors describe the socioeconomic characteristics and fertility patterns of female immigrants from Latin America to the United States, with a focus on reasons for fertility differentials. "Using the one per cent public use sample from the 1970 and 1980 United States census, we first compare changes in socio economic characteristics from 1970 to 1980, and then examine the determinants of fertility of female immigrants to the United States, aged 16-49, from four Latin American areas or countries of birth.... The findings...suggest that there are direct effects of demographic, assimilation, and socioeconomic variables beyond those mediated by the variables in each of these sets. Further, regardless of the model, the effect of the clusters of demographic characteristics is most apparent. Age categories and marital status are the strongest indexed determinants of immigrant fertility.... The effect of education and employment is strong. Among assimilation variables, duration of residence and language ability are significant determinants of Hispanic immigrant fertility." (SUMMARY IN FRE AND SPA)  相似文献

"The purpose of this paper...is twofold: first, to specify a way of calculating place utility so that potential migrants could move to the place where overall place utility is maximized; and second, which is more important, to reveal how decision-makers in the real world, who are acting within 'bounded rationalities'...,make their decisions on where to migrate. This study is supported by an empirical survey of recent Chinese immigrants to Edmonton [Canada].... The findings reveal that when people evaluate different places, they do not necessarily look for the one that generates the highest overall value or utility across all properties.... The study further indicates that the assumption underlying most microeconomic models (that maximizing utility or benefit is the ultimate rule for choosing one location out of several) has not been verified."

Sex offenders have used the Internet to identify and contact minors for sexual exploitation (Armagh, 1998; Hernandez, 2000; Lamb, 1998; Lanning, 1998). Yet little is known about how these individuals select their online victims. In order to gain a better understanding of this behavior, the online activity of 31 men who perpetrated or attempted to perpetrate contact sex offenses against minors they communicated with via the Internet, was examined. Three-fourths of the participants monitored chat room dialogue and almost one-half reviewed online profiles of minors in an attempt to identify potential victims. Recommendations to increase the online safety of children and adolescents are discussed.  相似文献

Many studies have documented significant differences in sexual desire between individuals of European and Chinese descent, but few have examined the mechanisms that underlie these differences. A recent study of university students found that sex guilt is one mechanism by which culture influences sexual desire among Chinese and Euro-Canadian women. The goal of this study was to examine whether sex guilt also mediates the relationship between ethnicity and sexual desire in a sample that is more representative of women in the general population. Euro-Canadian (n = 78; mean age = 42.1 years) and Chinese (n = 87; mean age = 42.8 years) women were recruited from the community. Euro-Canadian women reported greater sexual desire and less sex guilt. In the entire sample, sex guilt mediated the relationship between ethnicity and sexual desire such that the Chinese women reported greater sex guilt, which, in turn, was associated with lower sexual desire. Among the Chinese women, sex guilt mediated the relationship between mainstream acculturation (degree of Westernization) and sexual desire such that more Westernized Chinese women reported less sex guilt, which, in turn, was associated with greater sexual desire. These results support recent findings and further suggest that sex guilt may be one mechanism by which ethnicity affects sexual desire.  相似文献

We used data from a randomized controlled study of Oxford House (OH), a self-run, self-supporting recovery home, to conduct a cost-benefit analysis of the program. Following substance abuse treatment, individuals that were assigned to an OH condition (n = 68) were compared to individuals assigned to a usual care condition (n = 61). Economic cost measures were derived from length of stay at an Oxford House residence, and derived from self-reported measures of inpatient and outpatient treatment utilization. Economic benefit measures were derived from self-reported information on monthly income, days participating in illegal activities, binary responses of alcohol and drug use, and incarceration. Results suggest that OH compared quite favorably to usual care: the net benefit of an OH stay was estimated to be roughly $29,000 per person on average. Bootstrapped standard errors suggested that the net benefit was statistically significant. Costs were incrementally higher under OH, but the benefits in terms of reduced illegal activity, incarceration and substance use substantially outweighed the costs. The positive net benefit for Oxford House is primarily driven by a large difference in illegal activity between OH and usual care participants. Using sensitivity analyses, under more conservative assumptions we still arrived at a net benefit favorable to OH of $17,830 per person.  相似文献
