This prospective study applies family stress theory to the influence of personal, child, and familial factors on a mother's parenting stress during the first 3 years of her infant's life. Participants included 134 mothers and their infants at ages 1, 6, 15, 24, and 36 months from one site of a multisite, longitudinal study. Mother's personality was most predictive of parenting stress cross‐sectionally and longitudinally. Intimacy with partner reduced parenting stress early in the infant's life and at 36 months, whereas general social support was more important in the second year. Child temperament was influential at 1 and 36 months. Counterintuitively, mothers who were more satisfied with work or school choices were more likely to be chronically stressed. Implications are discussed. 相似文献

Our objective is to standardize and evaluate a combined physical and psychosexual therapy for women with provoked vestibulodynia. Twenty-four patients underwent the treatment program. Sessions with a psychosexual counselor included issues on sexual functioning, psychological adjustments, and stress elimination. Exercises for mucosal desensitization and reestablishment of pelvic floor function were supervised by a midwife. A questionnaire was used for evaluation at a minimum of 6 months after the treatment. The mean number of appointments to the counselor was 12 (4-24) and 15 (9-26) to the midwife during a mean period of 53 weeks (19-92). Nineteen women (79%) considered themselves to be cured or having greatly improved. Intercourse frequency was increased (p = 0.001) and coital pain was reduced (p = 0.02) after completing the treatment. Improvements in sexual functioning and coping strategies for psychological impairment and stress were reported. Women with provoked vestibulodynia benefit from a multidisciplinary treatment model including desensitization of the vestibular mucosa, rehabilitation of the pelvic floor, and psychosexual adjustments. 相似文献

Can governance impact directly on well-being? In this paper we examine subjective well-being using data for a cross section of countries from the World Values data set. We find that regional democratic satisfaction impacts on both individual happiness and life satisfaction. However, the impact is less evident for women, rich people and for those in rich countries. The fact that the governance variable analysis is based on regional differences in democratic satisfaction reminds us that governance and indeed happiness often differs within countries as well as between them. The use of regional satisfaction in this manner helps overcome endogeneity problems which would be present if we were to use individual democratic satisfaction. Other significant determinants of happiness include settlement size, marital status, income, unemployment and being part of a linguistic minority/majority grouping. 相似文献

We present an integrative measure of exposure and sensitivity components of vulnerability to climatic and demographic change for the African continent in order to identify “hot spots” of high potential population vulnerability. Getis-Ord Gi* spatial clustering analyses reveal statistically significant locations of spatio-temporal precipitation decline coinciding with high population density and increase. Statistically significant areas are evident, particularly across central, southern, and eastern Africa. The highly populated Lake Victoria basin emerges as a particularly salient hot spot. People located in the regions highlighted in this analysis suffer exceptionally high exposure to negative climate change impacts (as populations increase on lands with decreasing rainfall). Results may help inform further hot spot mapping and related research on demographic vulnerabilities to climate change. Results may also inform more suitable geographical targeting of policy interventions across the continent. 相似文献

This paper aims to analyze the relationship between the various dimensions of social capital and subjective wellbeing. Data used in this study come from the fourth wave of the European Social Survey and different measures of wellbeing are used to take account of both the cognitive and affective processes of individual wellbeing (i.e. life satisfaction, happiness, and subjective wellbeing). A factor analysis is performed to summarize information coming from a large set of variables into different components corresponding to each dimension of social capital (i.e. networks, norms, and trust). Among the results, we find that the impact of social capital on subjective wellbeing differ depending on the component of social capital which is under analysis. In particular, social networks, social trust and institutional trust are the components that show a higher correlation with subjective wellbeing. Furthermore, in addition to the positive effects of the individual variables, our results suggest that social capital at the aggregate level positively correlates with individual wellbeing, thus pointing to an external or environmental effect of social capital. 相似文献

One of the challenging problems in neuroimaging is the principled incorporation of information from different imaging modalities. Data from each modality are frequently analyzed separately using, for instance, dimensionality reduction techniques, which result in a loss of mutual information. We propose a novel regularization method, generalized ridgified Partially Empirical Eigenvectors for Regression (griPEER), to estimate associations between the brain structure features and a scalar outcome within the generalized linear regression framework. griPEER improves the regression coefficient estimation by providing a principled approach to use external information from the structural brain connectivity. Specifically, we incorporate a penalty term, derived from the structural connectivity Laplacian matrix, in the penalized generalized linear regression. In this work, we address both theoretical and computational issues and demonstrate the robustness of our method despite incomplete information about the structural brain connectivity. In addition, we also provide a significance testing procedure for performing inference on the estimated coefficients. Finally, griPEER is evaluated both in extensive simulation studies and using clinical data to classify HIV+ and HIV? individuals. 相似文献

Some bootstrap and boosting methods for problems related to classification are introduced in this article. The first method chooses better boosting weights by using a bootstrap search algorithm. The second method is a good way to define a classification frontier. A new formulation for boosting in linear discriminant analysis is given. Since in this new formulation the uncertainty is represented by the weighted covariance matrix, it is more appropriate from the conceptual point of view. Simulation results show that the proposed methods perform well in data analysis. 相似文献

We use administrative data about new legal permanent residents to show how family unification chain migration changed both the age and regional origin of US immigrants. Between 1981 and 1995, every 100 initiating immigrants from Asia sponsored between 220 and 255 relatives, but from 1996 through 2000, each 100 initiating immigrants from Asia sponsored nearly 400 relatives, with one‐in‐four ages 50 and above. The family migration multiplier for Latin Americans was boosted by the legalization program: from 1996 to 2000, each of the 100 initiating migrants from Latin America sponsored between 420 and 531 family members, of which 18–21 percent were ages 50 and over. 相似文献
