Abstract

Abortion decisions have a potentially meaningful effect on the lives of men. Previous research suggests that both men and women generally believe that men have the right to be involved in such decisions. However, very little research attention has been devoted to identifying individual difference correlates of discrepant levels of endorsement for male involvement in abortion decisions. The extent to which abortion attitudes (on a pro-choice to pro-life continuum), conceptualization of abortion as strictly a female issue, and interest in the issue operate as effective predictors of the appropriate level of male involvement in abortion decisions was examined in a sample of 1,387 college students. Results of a multiple regression analysis revealed that 44% of the variance in male involvement scores was explained by the predictor variables.  相似文献

Using survey data from Earned Income Tax Credit (EITC) recipients in Madison County, New York, we evaluate the effectiveness of the EITC in improving the economic well-being of low-income households. In particular, we examine the impact of the EITC across household types. For tax years 2002 through 2004, we find that the EITC is responsible for significantly lowering the poverty rate of EITC recipients, from 57 to 49%. In fact, for households below the poverty line, the EITC fills 31% of the gap between their adjusted gross income and the poverty line. The EITC has the largest impact on single parent households, lowering their poverty rate by 11.2 percentage points and reducing their poverty gap by almost 35%. However, the EITC has negligible effects on the poorest households in the sample—childless singles. A majority (64%) of EITC recipients intends to use at least some of the refund on basic needs and almost half plan on using part of their refund for debt repayment. This suggests that the EITC helps the majority of recipients get by but does not increase their economic mobility. Somewhat surprisingly, single parent households in the sample are not that different from married parent households in terms of EITC amounts, poverty rates, use of credit, and participation in government programs, despite earning less.  相似文献

The investigation on the identification of outliers in linear regression models can be extended to those for circular regression case. In this paper, we propose a new numerical statistic called mean circular error to identify possible outliers in circular regression models by using a row deletion approach. Through intensive simulation studies, the cut-off points of the statistic are obtained and its power of performance investigated. It is found that the performance improves as the concentration parameter of circular residuals becomes larger or the sample size becomes smaller. As an illustration, the statistic is applied to a wind direction data set.  相似文献

In this study we update analyses of the 1977 QES (Zipp, 1991) using data from the 1997 National Study of the Changing Workforce. We use hierarchical linear modeling procedures to partition the variance in a wide variety of indicators of workers' experiences. Most variation was associated with the individual level of analysis, but significant and nontrivial variation also was associated with the organizational and industrial levels. Although workers in smaller organizations reported lower earnings, fewer benefits, and less education than their counterparts in larger organizations, they also reported experiencing less discrimination, better fit between their actual and desired work hours, more supportive work environments and loyalty to their employers, less burnout or interference between work and family, and shorter commute times.  相似文献

The external environment of a corporation is one of the major determinants of its strategy. While this view is readily accepted, the tools to monitor this important determinant are still relatively underdeveloped. The authors have developed a managerial process which fills this gap by enabling an organization to assess its external environment effectively and economically. The approach helps executives identify major forces for strategic change in the market and non-market dimensions of the environment. The relevance of these changes is determined by measuring their impact on the mission and the strategies of the company. The process, furthermore, provides a starting point for assessing an organization's capabilities to respond to these forces for change.  相似文献

This investigation compares school outcomes for students who differ in the extent to which they perceive their parents, friends, and teachers—each alone and in combination—as important sources of social support. Findings indicate that middle and high school students who perceive high supportiveness from all three sources of support, as opposed to none, one, or two, have better attendance; spend more hours studying; avoid problem behavior more; have higher school satisfaction, engagement, and self-efficacy; and obtain better grades. Positive school outcomes are promoted when teacher support is perceived in combination with perceived support from parents and friends. Implications of the results for human service providers are presented.  相似文献

The investigation of subtypes of violent men could provide invaluable information to researchers and clinicians. In earlier studies, investigators examined whether subtypes of male batterers could be identified based on physiological markers in combination with observational and self-report perspectives. In a sample of batterers and their wives, they found a physiological marker that discriminated between two groups of violent men on several interesting dimensions. To highlight the importance of studying batterer typologies, the present study examined differences in marital interaction patterns across the two groups of batterers. Analyses revealed clinically relevant patterns of interaction in the two groups, and effect sizes indicating the possibility of differences between the two types of batterers. Implications for future research as well as therapy are discussed.  相似文献
