This study examines the influence of a selected set of determinants of contraceptive method switching in rural Sri Lanka. Of interest is the question of how change in contraceptive practice at the individual level can account for patterns observed at the aggregate level. Based on calendar data on contraceptive use over a 3-year period, collected for more than 3,000 married women in a 1986 survey, the multivariate analysis shows that women who attain all or a significant proportion of their desired fertility tend to switch to more effective methods. Women who experience method failure tend to switch methods, usually to a type that is more effective. The woman's background determinants of age and education have small but significant effects on method switching, whereas the effect of household economic well-being is not significant. There is strong indication that rural couples are practicing contraception in a nonrandom fashion, switching methods in accordance with changes in their fertility motivations and contraceptive experience.  相似文献

This paper discusses findings from a recently completed study of adolescent foster care, which included a detailed assessment of the parenting approaches and strategies used by the foster carers of adolescents in long‐term placements. Sixty‐eight foster carers were interviewed at two points in time. The first interview was conducted two months after the start of a new adolescent placement and the second after the placement had been continuing for a year, or at the point of disruption if this occurred earlier. The interview schedules were designed specifically for this study and were based upon well‐established techniques developed in other studies of parenting. They enabled the researchers to make summary ratings for each carer on established dimensions of parenting such as control and discipline, responsiveness and the level of engagement with the child. The researchers assessed how these strategies changed and developed in relation to the young person's behaviour and whether these approaches influenced either the likelihood of placement disruption or the quality of the placement for the child. This paper describes the parenting strategies used by the foster carers, highlighting the areas of parenting that significantly affected the placement outcomes and the corresponding implications for policy and practice.  相似文献

Starting with a reflection on the September 11th, 2001, terrorist attacks on the Pentagon and the World Trade Center and the corporate fraud and bankruptcies of 2002, the authors provide an overview of the professional literature concerning the origins, evolution, practice, and future implications of the work ethic in the United States. Discussion focuses on the American work ethic from both a historical and a modern‐day perspective, highlighting the formation of what is now considered a major paradigm of work; views on the changing nature of the work ethic, especially for women and members of minority groups; and implications for career counselors.  相似文献

The relationship between family norms and practices of emotional expression and nonverbal communication skill was investigated in two studies and a meta-analysis. Based on the general socialization hypothesis presented in the literature, specific predictions were for (a) better non-verbal judging skill in individuals whose families inhibit expressiveness, relative to individuals whose families value expressiveness, and (b) better nonverbal sending skill in individuals whose families value expressiveness, relative to individuals whose families inhibit expressiveness. In the two studies, family expressiveness styles, measured by college students' retrospective self-reports, was related to the skills of sending and judging emotional communications via voice tone and judging emotional communications via facial expression.This research was conducted while the author was supported by a National Science Foundation Graduate Fellowship at the John Hopkins University. Portions of this paper were presented at the meeting of the Eastern Psychological Association, Baltimore, MD 1982. Many thanks are due to Judith A. Hall, Cynthia Rand, Marylee Taylor, and Miron Zuckerman, who shared their unpublished data. Additionally, the helpful suggestions of Judith Hall and the reviewers are gratefully acknowledged.  相似文献

Many have questioned whether voters are able to hold incumbent officials electorally accountable through a retrospective voting strategy. We examine U.S. Senate elections from 1962 to 1990 in forty-one states, explaining which incumbents ran for reelection and their success in seeking reelection. We find that an incumbent's deviation from her state party platform decreases the probability that she will run for reelection and win if she runs. Furthermore, the electoral mechanism is found to be more efficient when voters are better informed. Finally, we find that our divergent party platform model provides a better fit than the median voter model.  相似文献

A nonparametric estimator of the probability distribution of time-to-tumor is incorporated into an algorithm for calculating linearly extrapolated dosage limits from an animal carcino-genesis bioassay. The procedure is illustrated with tumor data from a mouse bioassay with 2-acetylaminofluorene. Extrapolated dosage limits for an excess risk of 10-6 differ by only a factor of 2 across the six replicates of the experiment.  相似文献

The effects of maternal expressiveness and children's gender on children's nonverbal expressiveness were assessed in two settings. In the laboratory, 30 boys and 30 girls of kindergarten age were unobtrusively videotaped while talking about happy, sad, and fearful experiences and while experiencing three social situations designed to elicit happy, disappointed, and apprehensive feelings. Videotapes were rated for emotion expression, using global ratings and EMFACS codes. In school, teachers rated these children's expression of four discrete emotions. In both the laboratory and school settings children were more positively expressive than negatively so, and positive and negative expressiveness were unrelated. In the laboratory children's positive expressiveness was consistent across the three social situations, but negative expressiveness varied across affective context. In both settings, children of low-expressive mothers were more positively expressive than children of high-expressive mothers, who tended to be more negatively expressive than children of low-expressive mothers. The difference in negative expression appeared most striking for anger. Gender was not predictive of children's expressiveness in either setting  相似文献
