This article reports the results of a telephone survey (n = 1002) conducted in November 2008, which aimed to identify parenting stress and perceived family functioning of Chinese parents in Hong Kong; to explore the effects of the parents’ socio‐demographic characteristics (gender, family income, education and family structure) on the aforementioned stress and functioning variables; and to examine the interrelationship among these characteristics and the two variables in question. Results showed that the reported parenting stress was at average level, while the perceived family functioning was slightly below average. The results also indicated that the parenting stress of mothers, single parents, the low‐income and the less‐educated was higher than that of fathers, parents of nuclear and extended families, the high‐income and the better‐educated. Socio‐demographic characteristics except the parent’s gender had similar effects on perceived family functioning. Higher parenting stress was associated with lower family functioning, and explained a larger variance in the perceived family functioning than the socio‐demographic characteristics taken alone. The results of the study have provided empirical support regarding the interrelationships among the vulnerable groups in society, parenting stress and perceived family functioning. Implications of the study for social work practice are discussed.  相似文献

In an affected‐sib‐pair genetic linkage analysis, identical by descent data for affected sib pairs are routinely collected at a large number of markers along chromosomes. Under very general genetic assumptions, the IBD distribution at each marker satisfies the possible triangle constraint. Statistical analysis of IBD data should thus utilize this information to improve efficiency. At the same time, this constraint renders the usual regularity conditions for likelihood‐based statistical methods unsatisfied. In this paper, the authors study the asymptotic properties of the likelihood ratio test (LRT) under the possible triangle constraint. They derive the limiting distribution of the LRT statistic based on data from a single locus. They investigate the precision of the asymptotic distribution and the power of the test by simulation. They also study the test based on the supremum of the LRT statistics over the markers distributed throughout a chromosome. Instead of deriving a limiting distribution for this test, they use a mixture of chi‐squared distributions to approximate its true distribution. Their simulation results show that this approach has desirable simplicity and satisfactory precision.  相似文献

This article examines the representation of Black women's weight in contemporary diet advertising and African American film. It positions socioeconomic class as a significant factor that distinguishes between “good” weight and “bad” weight. I argue that there is a distinction to be made between representations of poor and working-class fat Black women and middle-class fat Black women. The increased presence of Black women as diet spokeswomen is also questioned. The social construction and filmic representation of the African American cuisine “Soul Food” and the political economic notion of neoliberalism are used as frameworks to deconstruct how notions of self-discipline, personal responsibility, and citizenship impact upon Black women's bodies. As a case study, I examine the careers of Oprah Winfrey and Gabourey Sidibe and the ways in which their weight has been differently coded based on class, the neoliberal rhetoric of “personal responsibility,” and food. I ultimately critique how contemporary media has helped to shape contemporary discourses on Black women's weight.  相似文献

This study sought to determine whether the levels of financial satisfaction reported by college undergraduates and graduates differ in relation to whether they funded their college education by working or borrowing or a combination of the two. Data for this study came from a survey sample of full-time freshmen that formed the basis of a longitudinal study conducted at a large public university. Funding sources examined were grouped into those who worked only, those who borrowed only, those who worked and borrowed, and those who used grants, scholarships, or other sources of money to fund their college education. Compared to those who had student loans, those who had financed college with grants, scholarships, or other money (usually from family and/or friends) were more likely to report greater financial satisfaction than those who had used student loans to pay for college. There was evidence that this was only true during college rather than after college. The results obtained suggest that merely possessing a student loan may not necessarily decrease the level of financial satisfaction as many suspect, especially considering other funding alternatives such as working during college. While there was no significant impact of these funding strategies on financial satisfaction either during or after college, there was evidence for possible thresholds at which overall student loan balances may begin to erode financial satisfaction. The results obtained suggest that student loans may not decrease the level of financial satisfaction as much as many have suspected when compared with working to pay for college, as long as the amount of the student loan is not excessive, and is not accompanied by other types of debt (which also reduced financial satisfaction).

The relation betwee freedom and social integration is examined using the theories of Landecker and of Kolb. Data are from a purposive sample of 25 communal and formal organizations. Information was gathered through questionnaires and participant observation. Two dimensions of integration are used, normative and consensual; three types of freedom are employed, ego, conditional, and disciplined. The basic hypothesis is that the dimensions of integration vary with the types of freedom. Normative and consensual integration will be positively associated with disciplined freedom, these dimensions will vary inversely with ego freedom, and conditional freedom will occupy an intermediate position. The hypotheses are confirmed through multiple regression analysis. Durkheim's mechanical solidarity is seen to be associated with disciplined freedom. Because we consider freedom and integration inseparable, this association is labeled consensual integration. Again following Durkheim, we hypothesize a new form of integration—contractual—based on ego freedom. They type accompanied by conditional freedom is called provisional integration. Observations are offered on the relation of these forms of integration to social change.  相似文献

The accumulated knowledge on the development of children in residential settings covers a lot of ground but leaves a great deal unturned. The article summarises what is known about child development in the context of residential settings and concludes that there is little evidence to draw on to make clear recommendations about what types of children are likely to benefit from what types of residential settings. It maintains that, in the absence of evidence, policy and practice regarding residential care often has been guided by ideology. Residence has become a place of last resort for young people who cannot receive the support and/or safety they need from their own families or from foster families, or who pose a danger to others. The article calls for more rigorous evaluations of the impact of residence on child outcomes as well as concerted efforts to apply research evidence to policy and practice.  相似文献

A correlated probit model approximation for conditional probabilities (Mendell and Elston 1974) is used to estimate the variance for binary matched pairs data by maximum likelihood. Using asymptotic data, the bias of the estimates is shown to be small for a wide range of intra-class correlations and incidences. This approximation is also compared with other recently published, or implemented, improved approximations. For the small sample examples presented, it shows a substantial advantage over other approximations. The method is extended to allow covariates for each observation, and fitting by iteratively reweighted least squares.  相似文献
