The union voting intention literature shows that many nonunion employees who indicate that they think unions are instrumental in increasing wages, benefits, and working conditions would vote against forming a union. Although American workers have often been characterized as pragmatic with regard to their support for unions, the “disconnect” between union beliefs and union voting intentions just described suggests that more subtle forces are at work. In this paper, it is shown empirically that union instrumentality is a limited predictor of union voting intentions for a recent national cross-section of workers. Rather, more general feelings toward unions and employers are primary. These accounted for a large portion of the variance in union voting intentions, with general feelings towards unions by far the most critical predictor. A concluding section discusses whether the results may reflect changes in union power and changes in employee views of unions. Areas for future research are discussed.  相似文献

The Family Inventory of Resources and Stressors (FIRST) has been shown to have adequate psychometric properties in the assessment of families of children with emotional and behavior disorders (EBD). However, the extent to which ethnic/racial and developmental differences moderate the psychometric properties of this instrument is unknown. The study sample consisted of 150 families with an EBD child consecutively admitted to the Astor Transitions Program. This study seeks (1) to conduct a psychometric analysis of the FIRST subscales among African American and Hispanic/Latino families with older students versus early childhood students with EBD, and (2) to determine whether profiles will show greater stress for families of older students due to longer exposure to their EBD. Alpha coefficients were computed with a cutoff of 0.70 (or higher) indicating acceptable internal consistency reliability. Criterion variables reflecting family environment, mental health, and level of service correlated with relevant FIRST subscales assessed validity. Ethnic/racial and developmental effects were found to moderate the psychometric properties of the FIRST. No statistically significant between-group mean differences on the FIRST were found for families of early childhood versus older EBD students. Despite evidence of response bias on the part of families and lack of standardization during test administration by caseworkers, the current findings still reveal adequate reliability and limited validity of FIRST subscales.  相似文献

This study investigates gender-specific changes in the total financial return to education among persons of prime working ages (35–44 years) using U.S. Census data from 1990 and 2000, and the 2009–2011 American Community Survey. We define the total financial return to education as the family standard of living as measured by family income adjusted for family size. Our results indicate that women experienced significant progress in educational attainment and labor market outcomes over this time period. Ironically, married women’s progress in education and personal earnings has led to greater improvement in the family standard of living for married men than for women themselves. Gender-specific changes in assortative mating are mostly responsible for this paradoxical trend. Because the number of highly educated women exceeds the number of highly educated men in the marriage market, the likelihood of educational marrying up has substantially increased for men over time while women’s likelihood has decreased. Sensitivity analyses show that the greater improvement in the family standard of living for men than for women is not limited to prime working-age persons but is also evident in the general population. Consequently, women’s return to education through marriage declined while men’s financial gain through marriage increased considerably.  相似文献

The matched-pairs methodology is becoming increasingly popular as a means of controlling extraneous factors in business research. This paper develops discriminant procedures for matched data and examines the properties of these methods. Data from a recent study by Hunt [14] on the determinants of inventory method choice are used to contrast the performance of the different methods. While all of the methods yield the same set of discriminating variables, those procedures that allow for the dependence among observations within a pair provide greater classificatory power than traditional multivariate techniques.  相似文献

Using the National Longitudinal Survey of Youth 1979, we replicate previous estimates of the marital wage differential for white men, extend the analysis to African American men, then explain the within and between race differentials. We first control for formal job training, then for cognitive skills, parental background, and self‐esteem with little effect. By contrast, the white differential but not the black differential disappears in fixed‐effects estimation. We reconcile the cross‐section/panel differentials by focusing on the distinct identification conditions employed by each technique. Men who never change marital status play a significant role in white cross‐sectional estimates. (JEL J31, J12)  相似文献

Although there is a growing literature on the socioeconomic circumstances of the second generation, this issue has not been systematically considered for African Americans. To help fill this research gap, we investigate the extent to which the socioeconomic attainments of second‐generation African Americans differ from mainstream (i.e., third and higher generation) African Americans. Using data from the Current Population Survey and the 2000 Census, our results indicate that the schooling and wages of second‐generation African Americans consistently exceed those of third‐ and higher generation African Americans. Our findings also reveal that second‐generation African Americans do at least as well as whites in terms of years of schooling, but wage differentials differ significantly by gender. Second‐generation African‐American women earn wages that are at least as high as comparable white women, but second‐generation African‐American men earn wages that are, on average, about 16% less than measurably comparable white men. While no one theoretical perspective can account for all these results, they nonetheless indicate the continuing significance of racial disadvantage for African‐American men, including those with an immigrant background.  相似文献

We present data from a survey of deans at colleges and universities throughout the USA on the relative status of disciplines. Findings indicate that the relative status of Sociology within the academy is low, although there are several specific areas of high status—namely, concerning community involvement and engagement. Our analyses also investigate which areas of activity are most closely associated with the overall prestige of disciplines. Findings indicate that research-oriented activities are the most influential, while student-oriented activities have a more ambivalent association with status. Based on those findings, we offer suggestions for raising the status of the discipline, based on the cultivation of natural synergies linking research, community engagement, student training, and focusing on the benefits of establishing social science research centers associated with Sociology departments.  相似文献

In clinical trials, investigations focus upon whether a treatment affects a measured outcome. Data often collected include pre- and post-treatment measurements on each patient and an analysis of the change in the outcome is typically performed to determine treatment efficacy. Absolute change and relative change are frequently selected as the outcome. In selecting from these two measures, the analyst makes implicit assumptions regarding the mean and variance-mean relationship of the data. Some have provided ad hoc guidelines for selecting between the two measures. We present a more rigorous means of investigating change using quasi-likelihoods. We show that both absolute change and relative change are special cases of the specified quasi-likelihood model. A cystic fibrosis example is provided.  相似文献
