The impact of female employment on fertility preferences and behavior is examined with data from a 1980 national sample of Taiwanese women. The guiding hypothesis is that the greater the involvement of women in the impersonal market sector, the lower the fertility preferences, the longer the first birth interval, and the lower the actual fertility. Findings reveal that female employment in Taiwan is only weakly related to reproductive behavior. Even with increased participation of women in the modern market sector, female employment apparently has little impact on fertility preferences or behavior. Implications are drawn for policies aimed at lowering fertility.  相似文献

Residence background,migration, and fertility   总被引:1,自引:0,他引:1  
This paper attempts to clarify confusion concerning residence background and migration, and to demonstrate that each of these factors exerts an independent effect on fertility. Basic premises underlying the direction of the effect of these variables on fertility are examined. Data from the 1967 Survey of Economic Opportunity indicate that migration and residence background do have independent effects. It is concluded that present generalizations as to the direction of their influence should be submitted to closer scrutiny with additional data in the future. In addition, an index of rural exposure is developed to test the proposition that fertility varies directly with degree of rural experience. The data only partially support this hypothesis. Moreover, rural-to-urban migrants are found to have only slightly higher fertility than the receiving urban-origin population.  相似文献

Evidence-based behavioral parent training programs (BPTs) have been recommended as a primary prevention strategy for child maltreatment, and use of BPTs is increasing. As these programs are implemented in new contexts and among new populations, the cultural relevance of these programs and need for adaptations or modifications must be considered. The purpose of this study was to assess the types of cultural adaptations that are being made to a widely implemented BPT, SafeCare, by providers working with families involved in the child welfare system, and to explore the need for more systematic adaptations. Eleven SafeCare providers, from six states, participated in individual, semi-structured interviews. Overall, the providers did not recommend systematic adaptations of the model for specific ethnic groups. However, they provided general and specific information regarding SafeCare components that require adaptation on a case-by-case basis, which is likely to be applicable to many BPTs. More research is needed to develop clear guidance about when and how to assess the need for cultural adaptations and how to institute adaptations that improve rather than weaken evidence-based programs. By sharing data and experiences, purveyors can contribute to the body of knowledge about adaptation.  相似文献

Why Has Safety Improved at Rail‐Highway Grade Crossings?   总被引:2,自引:0,他引:2  
The number of collisions and fatalities at rail-highway intersections in the United States has declined significantly over the past 30 years, despite considerable increases in the volume of rail and highway traffic. This article disaggregates the improvement into its constituent causes. Negative binomial regressions are conducted on a pooled data set for 49 states from 1975 to 2001. The analysis concludes that about two-fifths of the decrease is due to factors such as reduced drunk driving and improved emergency medical response that have improved safety on all parts of the highway network. The installation of gates and/or flashing lights accounts for about a fifth of the reduction. The development in the 1970s and early 1980s of the Operation Lifesaver public education campaign, and the installation of additional lights on locomotives in the mid 1990s, each led to about a seventh of the reduction. Finally, about a tenth is due to closure of crossings resulting from line abandonments or consolidation of little-used crossings.  相似文献

OBJECTIVE AND PARTICIPANTS: A sample of 231 students attending a private liberal arts university in central Alberta, Canada, completed a 5-day time diary and a 71-item questionnaire assessing the influence of personal, cognitive, and attitudinal factors on success. METHODS: The authors used 3 success measures: cumulative grade point average (GPA), Personal Success--each participant's rating of congruence between stated goals and progress toward those goals--and Total Success--a measure that weighted GPA and Personal Success equally. RESULTS: The greatest predictors of GPA were time-management skills, intelligence, time spent studying, computer ownership, less time spent in passive leisure, and a healthy diet. Predictors of Personal Success scores were clearly defined goals, overall health, personal spirituality, and time-management skills. Predictors of Total Success scores were clearly defined goals, time-management skills, less time spent in passive leisure, healthy diet, waking up early, computer ownership, and less time spent sleeping. CONCLUSIONS: Results suggest alternatives to traditional predictors of academic success.  相似文献

Previous scholarship linking marital infidelity and divorce has tended to have 2 limitations: focusing on young marriages and overlooking the influence of religiosity. Using data from the panel study of Marital Instability over the Life Course (N = 763), we address both of these limitations. Using structural equation modeling and proportional hazards modeling, we examine the effect of religiosity on marital infidelity and subsequent divorce among couples married for at least 12 years. Our analyses reveal that religiosity reduces the likelihood of marital infidelity among these couples. However the effect of religiosity on the likelihood of a subsequent divorce is more complicated: Religiosity appears to indirectly reduce the likelihood of a subsequent divorce by increasing levels of marital happiness. Surprisingly, no influence is found of marital infidelity on marital stability or divorce. Implications for scholars concerned with marital stability are discussed.  相似文献

Ryan and Martinson (1983) Ryan, M. and Martinson, D. L. 1983. The PR officer as corporate conscience. Public Relations Quarterly, 28(2): 2023.  [Google Scholar] and other scholars argued that the corporate conscience role should belong in the public relations function. But, how common is the use of ethics counsel among public relations professionals? This qualitative research found that many public relations practitioners indeed perform the role of ethics counsel or corporate conscience in their organizations. However, a state of neglect of this role exists in terms of education and support—even lacking support among some public relations practitioners! The well-being of both organizations and publics could be enhanced through both academic study and professional attention to public relations managers performing the role of ethics counsel to the dominant coalition.  相似文献
