This research provides a multivariate explanation of monthly (N = 243) birth rate variation for African-American women 20--24 years of age using time series analysis. The research explains both seasonal and intermediate variation in these birth rates. The independent variables were selected for their relationship to: economic understandings of fertility; developing understandings of the relationship of photoperiod to reproductive functioning; routine activity theory; and the relationship of birth rates to quality of life perspectives. The findings of this research are interpreted with respect to important developments and understandings in the quality of life literature. Concepts of 'compensatory validation' and 'contextual compatibility' are derived from quality of life understandings and Rainwater's (1974) concept of 'validating activities'. The previously identified importance of domains of intimacy, sexual activity and family life (Cummins, 1996; Alfonso et al., 1996) are related to empirical findings concerning the conception of children and incorporated into these theoretical concepts. Nine explanatory variables were selected. Theoretical, research and policy implications are summarized. 相似文献

Most data have a space and time label associated with them; data that are close together are usually more correlated than those that are far apart. Prediction (or forecasting) of a process at a particular label where there is no datum, from observed nearby data, is the subject of this article. One approach, known as geostatistics, is featured, from which linear methods of spatial prediction (kriging) will be considered. Brief reference is made to other linear/nonlinear, stochastic/deterministic predictors. The (linear) geostatistical method is applied to piezometric-head data around a potential nuclear-waste repository site. 相似文献

Philip Gilligan 《Child Abuse Review》2009,18(2):94-110
Diverse, but significant, phenomena have combined to raise both the profile of issues related to religion and child abuse and the need for professionals to understand and respond appropriately to them. The nature of some of these issues is explored and attempts made to clarify them. Data collected by the author primarily from questionnaires completed by professionals involved in child protection and safeguarding work are analysed and discussed. Some patterns are identified and explored. Finally, it is suggested that, despite the apparent emergence of a more general recognition and acknowledgement of these issues amongst many professionals, relevant day‐to‐day practice remains largely dependent on individual views and attitudes. Moreover, practitioners are able to continue with ‘religion‐blind’ and ‘belief‐blind’ approaches without these being significantly challenged by agency policies or by professional cultures.

Why Have Children in the 21st Century? Biological Predisposition, Social Coercion, Rational Choice 总被引:1,自引:0,他引:1
This review examines arguments and evidence pertaining to the question: why have children in settings where the net economic costs of children are clearly substantial? Thereview is organized around three themes: biologicalpredispositions, environment (social coercion) and rationalchoice. Specifically, we explore the argument that evolution hasproduced sets of genes that predispose persons to childbearing bymaking sex and parenthood pleasurable. We review sociologicalarguments regarding the pronatalism/antinatalism of societalinstitutions. Finally, we discuss arguments that stress therationality of childbearing decisions by appealing to biologicalpredispositions and the economic and non-economic values ofchildren. The authors speculate that while a modern socialstructure and rationale supportive of childbearing could beconstructed, such changes are not inevitable and may be difficultin the face of competing interests. Moreover, future social andtechnological change could alter the context of childbearingsubstantially. This uncertainty complicates policyrecommendations. 相似文献

SOLIDARITY AND DRUG USE IN THE ELECTRONIC DANCE MUSIC SCENE 总被引:1,自引:0,他引:1
Current research and theory on rave culture has articulated a link between solidarity and drug use, although the precise nature of this relationship remains unclear. Work conducted in the field of cultural studies contends that while rave participants engage in drug use, it is by no means the exclusive source of solidarity. However, work in the fields of public health and medical science portrays rave culture as a site of extensive drug consumption and personal risk, where solidarity is dismissed or dubiously acknowledged as chemically induced. Prior research has not sought to reconcile this tension, or to consider how the relationship between drug use and solidarity may have changed over time. Using data from a multimethod ethnography of the rave scene in Philadelphia, we found the drug use–solidarity relationship substantially more complicated than prior scholarship has articulated. Our discoveries, consequently, provide clarification of this relationship as well as advance the literatures on solidarity, collective identity, youth culture, and music scenes. 相似文献

Philip W. Meilman PhD 《Journal of American college health : J of ACH》2013,61(1):43-47
Abstract To provide first-rate services to students, college health services need the best possible staff. Managers and supervisors play a critical role in guiding the work of their employees so as to enhance performance. Reference checks for new employees and regular performance appraisal dialogues for ongoing employees are important tools in this process. The author discusses these issues and suggests formats for reference checks and performance appraisals. 相似文献
