The goal of the present study was to examine the relationship between premarital cohabitation experience and marital communication in an effort to understand the robust finding known as the cohabitation effect, whereby couples who cohabit before marriage have greater marital instability than couples who do not cohabit. Observed marital problem solving and social support behavior were examined as a function of premarital cohabitation experience in a sample of 92 couples in the first 2 years of their first marriages. Spouses who cohabited before marriage demonstrated more negative and less positive problem solving and support behaviors compared to spouses who did not cohabit. Sociodemographic, intrapersonal, and interpersonal functioning variables did not account for the association between cohabitation experience and marital communication. 相似文献

Summary. The first British National Survey of Sexual Attitudes and Lifestyles (NATSAL) was conducted in 1990–1991 and the second in 1999–2001. When surveys are repeated, the changes in population parameters are of interest and are generally estimated from a comparison of the data between surveys. However, since all surveys may be subject to bias, such comparisons may partly reflect a change in bias. Typically limited external data are available to estimate the change in bias directly. However, one approach, which is often possible, is to define in each survey a sample of participants who are eligible for both surveys, and then to compare the reporting of selected events that occurred before the earlier survey time point. A difference in reporting suggests a change in overall survey bias between time points, although other explanations are possible. In NATSAL, changes in bias are likely to be similar for groups of sexual experiences. The grouping of experiences allows the information that is derived from the selected events to be incorporated into inference concerning population changes in other sexual experiences. We use generalized estimating equations, which incorporate weighting for differential probabilities of sampling and non-response in a relatively straightforward manner. The results, combined with estimates of the change in reporting, are used to derive minimum established population changes, based on NATSAL data. For some key population parameters, the change in reporting is seen to be consistent with a change in bias alone. Recommendations are made for the design of future surveys. 相似文献

Outcomes of social policies have always been mediated by the discretionary agency of front‐line staff, processes which nevertheless have received insufficient attention in policy evaluation and in the social policy literature more broadly. This article takes the case example of the policy reforms associated with the Australian government's welfare‐to‐work agenda. Drawing on two discreet research projects undertaken at different points in the policy trajectory, the practices of social workers in Centrelink – the Commonwealth government's primary service delivery agency involved in welfare‐to‐work – is examined. Centrelink social workers have been and remain one of the core groups of specialist staff since the Department's inception in the late 1940s, working to improve the well being of people in receipt of income security. Their experiences of the recent past and their expectations of the future of their professional practice as welfare reform becomes more entrenched are canvassed. In summary, the discretionary capacity of the Centrelink social workers to moderate or shape the impact of policy on income security recipients is steadily eroding as this group of professionals is increasingly captured by the emerging practices of workfare. 相似文献

Meta-Analysis of Food Safety Information Based on a Combination of a Relational Database and a Predictive Modeling Tool 总被引:1,自引:0,他引:1

The management of microbial risk in food products requires the ability to predict growth kinetics of pathogenic microorganisms in the event of contamination and growth initiation. Useful data for assessing these issues may be found in the literature or from experimental results. However, the large number and variety of data make further development difficult. Statistical techniques, such as meta-analysis, are then useful to realize synthesis of a set of distinct but similar experiences. Moreover, predictive modeling tools can be employed to complete the analysis and help the food safety manager to interpret the data. In this article, a protocol to perform a meta-analysis of the outcome of a relational database, associated with quantitative microbiology models, is presented. The methodology is illustrated with the effect of temperature on pathogenic Escherichia coli and Listeria monocytogenes, growing in culture medium, beef meat, and milk products. Using a database and predictive models, simulations of growth in a given product subjected to various temperature scenarios can be produced. It is then possible to compare food products for a given microorganism, according to its growth ability in these products, and to compare the behavior of bacteria in a given foodstuff. These results can assist decisions for a variety of questions on food safety. 相似文献

This article explores the development and maintenance of familiar gendered employment patterns and practices in UK universities, which are exemplars of new modes of knowledge production, commodification and marketization. After discussing in detail the evidence of gender discrimination in UK higher education and the changes in the academic labour process consequent to the incorporation of universities, at least at the policy level, into the ‘knowledge economy’, institution‐specific data is used to highlight the gendered aspects of the research economy from the three intermeshing perspectives of research culture, research capital and the research production process. This nexus is constructed in such a way as to systematically militate against women's full and equal involvement in research. Lack of transparency, increased competition and lower levels of collegiate activity coupled with networking based on homosociability are contributing to a research production process where women are marginalized. 相似文献

Hicksian welfare theory is static in nature, but many decisions are made in a dynamic environment. We present a dynamic model of an agent's decision to purchase or sell a good under the realistic conditions of uncertainty, irreversibility, and learning over time. Her willingness to pay (WTP) contains both the intrinsic value of the good as in Hicksian theory plus a commitment cost associated with delaying to obtain more information. The Hicksian equivalence between WTP/Willingness to accept (WTA) and compensating and equivalent variations no longer holds. The WTP and WTA divergence may arise and observed WTP values are not always appropriate for welfare analysis. 相似文献

BackgroundThe prevalence of overweight and obesity is increasing amongst women of child bearing age. The objective of this study was to investigate the views and attitudes of providers of antenatal care for women who have a body mass index (BMI) of 30 kg/m2 and over.MethodsA qualitative study using focus groups was undertaken within the department of obstetrics and gynaecology at a large teaching hospital in south-eastern Australia. Three focus group discussions were held. One with hospital midwives (n = 10), one with continuity of care midwives (n = 18) and one with obstetricians (n = 5). Data were analysed using Interpretative Phenomenological Analysis (IPA).FindingsSix dominant themes emerged: (1) obesity puts the health of mothers, babies and health professionals at risk; (2) overweight and obesity has become the norm; (3) weighing women and advising about weight gain is out of fashion; (4) weight is a sensitive topic to discuss; (5) there are significant barriers to weight control in pregnancy; and (6) health professionals and women need to deal with maternal obesity. These themes are drawn together to form a model representing current health care issues for these women.ConclusionHealth professionals, who have a high BMI, can find it difficult to discuss obesity during antenatal visits with obese women. Specialist dietary interventions and evidence based guidelines for working with child-bearing women is seen as a public health priority by health care professionals. 相似文献
