A modified rational decision model incorporating salient events and social influences (particularly from sexual partners) is used to analyze adolescent women's consistent use of oral contraceptives (OCs) over a six-month period. Data are taken from a panel study of 308 clients of an inner-city family planning clinic. Expected OC use was computed for each subject on the basis of subjective expected utility (SEU) theory, and is found in multivariate analyses to be a significant predictor of actual OC use. In addition, variables representing baseline and follow-up partner influences, the salience of pregnancy for the subject, and positive side effects of OCs during the first months of use are found to predict OC use. Partner's support of OC use during follow-up and positive side effects of OCs are found to predict OC use among subjects for whom OC use was not the expected decision according to baseline SEU. Implications of the findings for models of adolescents' contraceptive behavior and for clinicians are discussed.  相似文献

Policy makers, parents, and the public are concerned with perceived declines in parents’ time with children. Data from two national surveys (N = 1,159 and N = 821) used in this study show that nearly half of parents report feeling too little time with children. Work hours are strongly related to these feelings, even controlling for time spent with children, and explain why fathers more than mothers feel time strain. For fathers, those whose youngest child is an adolescent feel more strain than similarly situated mothers. Controlling for work hours, single parents are not more likely than married parents to feel that they spend insufficient time with children.  相似文献

We test the longstanding hypothesis that ethnic groups organized around “segmentary lineages” are more prone to conflict. Ethnographic accounts suggest that in such societies, which are characterized by strong allegiances to distant relatives, individuals are obligated to come to the aid of fellow lineage members when they become involved in conflicts. As a consequence, small disagreements often escalate into larger-scale conflicts involving many individuals. We test for a link between segmentary lineage organization and conflict across ethnic groups in sub-Saharan Africa. Using a number of estimation strategies, including a regression discontinuity design at ethnic boundaries, we find that segmentary lineage societies experience more conflicts, and particularly ones that are retaliatory, long in duration, and large in scale.  相似文献

This paper describes mental health risks to the birth-to-three foster care population. The paper describes risks of a relational and contextual nature. Relational risk factors, which have been previously identified by foster care researchers and clinicians, include the following: 1. Poor attachment signaling by foster infants and toddlers; 2. Discomfort with infant and toddler dependency by some foster parents; and 3. Regulatory problems of foster infants and toddlers. Contextual risk factors include the following: 1. Lack of coordinated and coherent efforts to help foster infants and toddlers and; 2. Lack of support for the parent–child relationship during placement. A case example and discussion is offered to illustrate these risks.  相似文献

Using data collected in Athens, Greece in the spring of 1977, an effort was made to test the relationship between several objective socioeconomic indicators and subjective class perceptions and political attitudes. Our main concern was the effect of subjective class awareness and consciousness on selected political issues (pro-Western foreign policy, civil liberties, and economic conservatism) and voting. Our findings show that class and socioeconomic variables tend to be stronger predictors of socio-political attitudes than are status indicators. In addition, subjective perceptions of class (particularly capitalist political influence and limited societal opportunity), father's politics, and age are major explanatory variables for political attitudes and the way people perceive national and international issues. Perception that the upper class benefits most from clientelism was related to voting and economic conservatism. Working-class consciousness was important in explaining voting in 1977. Our research strategy suggests that for the future we should broaden the study of class consciousness and awareness by viewing it as multidimensional and including measurements based on both closed- and open-ended questions.  相似文献

A national sample of women and men working in early childhood education was drawn from the membership of the National Association for the Education of Young Children in order to assess their attitudes toward the suitability, professional practice, and administrative capabilities of men in early childhood education. Men and women were found to hold similar views toward the capabilities and roles of male preschool teachers across all these areas. The general lack of polarity of attitudes between men and women on many popularlyheld beliefs about men in the early childhood field is discussed in relation to previous alleged stereotyped attitudes toward male preschool teachers.  相似文献
