"Life expectancy and mortality increasingly are analyzed in the context of social factors. This study analyzes the impact of social position, marital status, and religious confession on cohort life expectancy. The analysis is based on [German data from the] Socio-Economic Panel Survey, wherein proxy-interviewee's parents have been used to estimate cohort mortality. Results confirm a lower mortality risk of the upper classes and of married persons. However, as opposed to other studies, Catholics do not have a lower, but even a higher mortality risk."

In recent years, joint custody and co-parenting of children after divorce or separation has received considerable attention. The authors advocate wider recognition of this option to sole custody and visitation, review pertinent legal and other literature, identify indications and contraindications, and briefly discuss the implications for social workers.  相似文献

Artifact in client satisfaction assessment is discussed and the results of a study of three factors thought to mediate client satisfaction ratings; (a) general life satisfaction, (b) mode of administration, and (c) psychological symptomatology, are reported. A standard client satisfaction questionnaire (CSQ) was modified to yield parallel forms and was administered orally and in writing to 92 clients in two mental health day treatment programs. Satisfaction ratings obtained from these clients were quite similar to out-patient ratings obtained in previous studies conducted in this setting and using the same measures. Oral administration of the CSQ produced 10% higher satisfaction ratings than written administration (p less than .05) and less missing data (p less than .01). Satisfaction ratings were also obtained using a simple graphic instrument. Graphic ratings were comparable to CSQ ratings. Satisfaction with life in general and level of psychiatric symptoms together accounted for 25% of CSQ variance. The implication of these findings for future client satisfaction research is discussed.  相似文献

During the summer of 1972 in-depth interviews were conducted with 96 Shoshone and Arapahoe Indian women living on the Wind River Reservation in Central Wyoming. All were aged 15-49 and were users of the reservation health service. It was found the women fell into 4 groups: current contraceptive users, 42.7%; pregnant or seeking to become pregnant, 10.4%; infertile due to menopause or sterilization, 18.8%; and fertile never-users, 28.1%. The contraceptive users tended to be older, married, and have as many children as they want. The fertile never-users tended to be in their teens and generally unmarried. When asked why they did not use contraception their answer was 'because I am not married.' It is suggested that general education on contraception be provided the younger women so that when they achieve desired family size they will be informed as to family planning methods. It was found that religious belief against contraception was important to the young never-users, but not to the women who had completed their families. In fact, 73% of the users said their religion, which most identified as Roman Catholicism, had no influence on their contraceptive use while 27% said they were aware of church disapproval but used contraception anyway.  相似文献

"The study compares determinants of internal and international migration intentions, drawing upon interview data from a sample of adults in Ilocos Norte, a largely rural province in the Philippines. A regression model is applied to test the relative determinants of intentions to migrate to Manila and to Hawaii. The study is based on a value-expectancy model of migration decision making. The results document the importance of subjective expectations related to the attainment of different values and goals in Manila and Hawaii."  相似文献

Abstract The practice of post-partum abstinence has been a long-standing tradition in many societies of tropical Africa, yet recent research suggests an erosion of the taboo on post-partum sexual relations as a means of fertility control. The current study among women in the lower income groups in Kinshasa, Zaire, provides evidence of this. There is strong motivation toward child-spacing, as shown by 80 per cent of the women who reported to be currently practising some means of fertility control: 73 per cent with traditional methods, only 7 per cent with modern contraceptives. There appears to be some carry-over of traditional practice, in that abstinence is related to the age and nursing status of the last born child. However, the most widely practised method is withdrawal. This suggests a desire on the part of this population for alternatives to abstinence, an issue with important implications for future family planning programs in Zaire.  相似文献
