Regression analysis of the 1947 and 1963 NORC occupational prestige scores for 45 occupations indicates that being white-collar may have contributed modestly to the prestige of the 24 nonmanual occupations in 1947, net of economic rewards and educational selectivity, but that any such effect had largely disappeared by 1963. The findings tend to support the view that the white-collar-blue collar distinction has become less important in American society. 相似文献

Selected social characteristics of individuals were examined for groups of villages simultaneously dichotomized by size, location relative to larger cities, and population change. The percent of people having a selected characteristic in each village group of the resulting eight-fold classification was taken as the dependent variable, and difference scores indicating main effects and first order interactions were obtained for each characteristic. The universe is the 375 incorporated places under 2500 in 1950outside the SMSAs of Wisconsin. Size of place was found to be important for the sex ratio, education and income levels, and labor force and occupational variables. Characteristics associated with nearness to a large city included income, male labor force participation, occupation, and industry. Growth was important for age and sex differences, education, income, and some labor force, occupation, and industry variables. An interaction between location and growth was found for several occupation and industry characteristics. The consistency between some of the results and previous research on larger places supports the contention that villages, although classified as rural, share many characteristics of urban centers. The industry and occupation differences by location, and the interaction between location and growth, strongly suggest that location is tied closely to function here. Places near cities over 25,000, especially those that are growing, may serve as residences for commuting blue-collar workers, or perhaps as small manufacturing centers, while most places more remote from cities continue to function as small service centers for a rural hinterland. 相似文献

Objectives: We examined the social, relational and network determinants of condom use and HIV testing among men who have sex with men (MSM) in Beirut. Methods: Two-hundred thirteen men were recruited via respondent driven sampling and administered a survey. Results: Sixty-four percent reported unprotected anal intercourse (UAI), including 23% who had UAI with unknown HIV status partners (UAIU); 62% of participants had tested for HIV. In multivariate analysis, being in a relationship was associated with UAI and HIV testing; lower condom self-efficacy was associated with UAIU and HIV testing; gay discrimination was associated with UAIU; MSM disclosure was associated with UAI, UAIU and HIV testing; and network centralization was associated with HIV testing. Conclusions: Multi-level social factors influence sexual health in MSM. 相似文献

The Varied Impact of Couple Relationship Breakdown on Children: Implications for Practice and Policy
This review of international literature assesses the impacts that the relationship breakdown of parents has on children and factors that can provide support should this occur. The parental separation process causes significant albeit short‐term distress for most children, with a minority reporting longer‐term outcomes such as socio‐economic disadvantage, behavioural problems, poor educational achievement, and physical and emotional health problems. Factors increasing the likelihood of sustained disadvantage include: poverty; poor parent–child relationships; continuing parental conflict, multiple transitions in family formation; and poor maternal mental health. Supporting the factors that can improve child outcomes, exploring opportune ways to strengthen couple and family relationships, and integrating the views of children (for example, in court‐based dispute resolution) are the leading implications for practice and policy. 相似文献

The prevalence of interval censored data is increasing in medical studies due to the growing use of biomarkers to define a
disease progression endpoint. Interval censoring results from periodic monitoring of the progression status. For example,
disease progression is established in the interval between the clinic visit where progression is recorded and the prior clinic
visit where there was no evidence of disease progression. A methodology is proposed for estimation and inference on the regression
coefficients in the Cox proportional hazards model with interval censored data. The methodology is based on estimating equations
and uses an inverse probability weight to select event time pairs where the ordering is unambiguous. Simulations are performed
to examine the finite sample properties of the estimate and a colon cancer data set is used to demonstrate its performance
relative to the conventional partial likelihood estimate that ignores the interval censoring. 相似文献

We design experiments to jointly elicit risk and time preferences for the adult Danish population. Since subjects are generally risk averse, we find that joint elicitation provides estimates of discount rates that are significantly lower than those found in previous studies and more in line with what would be considered as a priori reasonable rates. The statistical specification relies on a theoretical framework that involves a latent trade‐off between long‐run optimization and short‐run temptation. Estimation of this specification is undertaken using structural, maximum likelihood methods. Our main results based on exponential discounting are robust to alternative specifications such as hyperbolic discounting. These results have direct implications for attempts to elicit time preferences, as well as debates over the appropriate domain of the utility function when characterizing risk aversion and time consistency. 相似文献
