Abstract This paper assesses the relative impact of direct and indirect determinants of marital fertility in Pakistan, where the vast majority of women do not use any method of fertility regulation. Data came from the 1990/91 Pakistan Demographic and Health Survey, and models were estimated for women aged 15–49, 15–24, 25–34 and 35–49. The younger cohort may be the vanguard of change; change which may be masked by investigating only the conventional 15–49 age group. Findings indicate that unlike the older cohorts, the younger cohort does not have negative and significant relationships between education, employment and fertility; and, that the current use of family planning is positive and significant with fertility for the 35–49 cohort only. These findings suggest that there is a threshold or minimum number of children that a woman must produce before determinants such as current use of family planning, education and employment impact fertility. 相似文献

This longitudinal study examined the relationship between couple relationship satisfaction, parenting practices, parent depression, and child problem behaviors. The study participants (n = 148) were part of a larger experimental study that examined the effectiveness of a brief family-centered intervention, the Family Check-Up model. Regression analysis results indicated that our proposed model accounted for 38% of the variance in child problem behavior at Time 2, with child problem behavior and couple relationship satisfaction at child age 2 years each accounting for a significant portion of the variance in child problem behavior at age 3. Couple relationship satisfaction directly predicted child behavior problems over time. Clinical and research implications are discussed. 相似文献

A multidimensional block design (MBD) is an experimental design with d > 1 blocking criteria geometrically represented as a d-dimensional lattice with treatment varieties assigned to some or all nodes of the lattice. Intrablock analysis of variance tables for some special classes of two- and three-dimensional block designs with some empty nodes are given. Design plans and efficiencies for 31 two-dimensional designs, each universally optimal in defined classes of designs, and 7 three-dimensional designs, each nearly optimal in defined classes of designs, are listed in the appendices. A need for such designs is apparent when the blocking criteria are implemented successively and empty nodes do not represent wasted experimental units. 相似文献

We developed a flexible non-parametric Bayesian model for regional disease-prevalence estimation based on cross-sectional data that are obtained from several subpopulations or clusters such as villages, cities, or herds. The subpopulation prevalences are modeled with a mixture distribution that allows for zero prevalence. The distribution of prevalences among diseased subpopulations is modeled as a mixture of finite Polya trees. Inferences can be obtained for (1) the proportion of diseased subpopulations in a region, (2) the distribution of regional prevalences, (3) the mean and median prevalence in the region, (4) the prevalence of any sampled subpopulation, and (5) predictive distributions of prevalences for regional subpopulations not included in the study, including the predictive probability of zero prevalence. We focus on prevalence estimation using data from a single diagnostic test, but we also briefly discuss the scenario where two conditionally dependent (or independent) diagnostic tests are used. Simulated data demonstrate the utility of our non-parametric model over parametric analysis. An example involving brucellosis in cattle is presented. 相似文献

Rural Mothers’ Use of Formal Programs and Informal Social Supports to Meet Family Food Needs: A Mixed Methods Study 总被引:1,自引:1,他引:0

Much of the research on low-income families, welfare, and self-sufficiency has focused on urban populations. Further, many
of the studies on informal or social support available to and accessed by low-income families addressed needs such as childcare,
transportation, money, or housing and did not focus on food issues. This paper focuses on how formal government food assistance
programs and informal supports are utilized by rural low-income families as they work to meet their food needs. Drawing on
interviews from the multi-state “Rural Families Speak” project, we examine food security in relation to the use of formal
and informal supports. Additional analyses address how mothers view and describe their use of support to meet food needs. 相似文献

This study examined the role of the dispositional variables of attachment style and tolerance for ambiguity on the interpretation of relational repair messages. Respondents completed questionnaires that measured attachment style and tolerance for ambiguity and made interpretations of hypothetical repair messages from their spouses with varying levels of equivocation. The resulting interpretations were measured along the dimensions of honesty, competence, and politeness using Likert-type scales. Regression and multivariate analyses of variance (MANOVAs) demonstrated that both of the traits influenced the interpretation of repair messages, although in somewhat different ways and along different dimensions. 相似文献
