A reanalysis of the repeat abortion experience of New York City residents during July 1, 1970 to June 30, 1972 is undertaken on the basis of a probability model that generates repeat abortion ratios as a function of assumptions about fecundity, contraceptive efficiency, and exposure lengths. Tested are three hypotheses put forward by Daily et al. in a 1973 analysis: (i) the low repeat abortion ratio of .0245 is attributable in part to underreporting of registered induced abortions as repeat ones; (ii) a major part of the rise in repeat abortion ratios, from virtually zero to six percent over four consecutive six-month intervals, is explainable in terms of the rising volume of exposure time to risk of repeat abortion relative to the stream of initial abortions; and (iii) the higher abortion ratios of women in their twenties compared to those of older or younger women is ascribable to “differences in fecundity and intercourse frequency.” Support is found for the first two hypotheses, and a mixed outcome for the third. 相似文献

Summary Acceptors in national family planning programmes are becoming steadily younger, with fewer children. In the present analysis, which makes use of the computerized component projection scheme CONVERSE, it is shown that saturation of the older groups with users has a relatively minor role to play in reducing the mean age of new acceptors. Even where acceptance and continuation rates are high and follow the usual pattern of higher levels for the older women, the build-up of users in the upper age groups is not enough to produce major changes in the age of acceptors. Yet acceptor ages have fallen consistently and sharply in most national programmes, regardless of the general strength, duration, or method mix. The finding that the mechanical effects investigated here play rather a small part in the large empirical declines in acceptor ages suggests the need to investigate other explanations. For this, a critical need is more data than are at present available on trends in age-specific rates of acceptance in national programmes. 相似文献

Past research on child support finds that father–child contact increases as support payments increase. Enforcement policies such as wage withholding also may affect father–child contact even when the amount of support paid is not affected if they change bargaining power between parents or the salience of fathers’ child support obligations. I develop a model of the salience of child support obligations which predicts that introduction of automatic withholding will reduce contact between noncustodial parents and children independent of payment amount. I then examine whether paying child support via wage withholding affects fathers’ frequency of contact with their children and their provision of in-kind support using instrumental variables and bounded OLS techniques for selection on unobservables. Withholding appears to decrease father–child contact. Withholding effects do not occur when payments are made to government agencies or courts but are present when payments go directly to the mother, consistent with bargaining models. More frequent payment schedules are associated with more contact, consistent with salience effects. 相似文献

This study discusses the qualitative lessons learned from a joint social work difficult dialogue education project undertaken by students from a historically Black college and university (HBCU) and those from a predominantly White institution (PWI). The assignment utilized critical pedagogy as a guiding theory to facilitate difficult dialogues about diversity, privilege, and difference through social media and technology. Qualitative data analyzed from the project points to the usefulness and challenges of using social media and technology in facilitating difficult dialogues as well as the need to train students more purposely in the effective use of social media and technology during their education in order to prepare them for practice. 相似文献

Trends in juvenile offending in the United States since the 1970s are reviewed. Serious youth violence, co-occurring mental health and substance abuse problems among offenders, female delinquency, and other issues currently confronting the American juvenile justice system are examined. Policy considerations associated with recent trends in juvenile offending among American youth are identified. 相似文献

The task of recruiting and retaining ethnically diverse, qualified, and committed social workers in child welfare is challenging. Federal funding supporting BSW and MSW education has been a catalyst for university–agency partnerships across the country. An important goal of these partnerships is to prepare social work students with the knowledge, skills, and competencies for effective child welfare practice. The National Child Welfare Workforce Institute’s innovative child welfare traineeships program prepares students from 12 social work programs around the country. This study focused on diversity, competency attainment, and readiness for the job. Results showed that programs recruited ethnically diverse students, and after receiving child welfare–specific content and hands-on experiences in the field, students felt competent and prepared for child welfare work. 相似文献
