Hispanics are now the largest minority group in the United States and their presence is likely to continue to expand. Little is known, however, about the correlates of Hispanic identity or the processes that are involved in its maintenance. We investigate these issues by ascertaining and then seeking to understand the various associations between reported racial identities and Hispanic ethnicity using data from the Current Population Surveys. Restricting the sample to individuals who are known to have demographic origins in Latin America, our results indicate that persons with African or Asian racial identifications are substantially less likely than whites or Others to also identify as Hispanic. Relative to the first generation, Hispanic identification declines and the racial differences increase in the second generation. The exceptions in this regard are Others for whom racial and Hispanic identifications are the most highly associated for both the first and second generations. These findings are interpreted as reflecting various social processes that are involved in the development and maintenance of racial and ethnic identities. Our results provide insight into the complex, social nature of Hispanic identification in modern America.  相似文献

Utilizing data from the 1992–1994 Health and Retirement Study (HRS), this paper examines the question of whether three groups of older working-age women—childless women, mothers with at least one child at home or temporarily away at school, and mothers with all their children living away from home—were different or similar in their likelihood of retirement and their actual work status. The results show that the childless group and the child-not-at-home group were more likely than the child-at-home group to define themselves as retired, although the three groups were equally likely to engage in paid work activities. Both early childbearing history and ongoing parental financial obligations appear to influence women's willingness to assume a retiree versus a nonretiree status. The findings may reflect an emerging trend of retirement being a status symbol rather than a marker of complete cessation from the world of work.  相似文献

The intangible aspects of knowledge transfer in multinational corporations (MNCs) continue to be a crucial area of research in social science research and raise the issue of knowledge governance structures. The purpose of this conceptual note is twofold. Firstly, we believe that there is more than one governance structure for successful knowledge transfers and flows. We provide a typology of three governance structures: “exchange,” “entitlement,” “gifts.” Secondly, most MNCs will need to take advantage of all three or a combination of these three socially complex governance structures.  相似文献

We consider a single-machine scheduling problem such that the due dates are assigned to each job depending on its order, and the lengths of the intervals between consecutive due dates are identical. The objective is to minimize the total penalty for the earliness and tardiness of each job. The early penalty proportionally increases according to the earliness amount, while the tardy penalty increases according to the step function. We show that the problem is strongly NP-hard, and furthermore, polynomially solvable if the two types of processing times exist.

ABSTRACT

The proliferation of technology has been changing feedback delivery methods in organizations. However, the effectiveness of feedback delivery methods can vary depending on social dynamics (e.g., authority relations) in the organization. The current study was designed to examine the impact of authority relations and feedback delivery methods on performance. A total of 120 participants were recruited to work on a simulated cell-phone assembly task and were exposed to one of the four feedback conditions: (a) authority figure with face-to-face feedback, (b) authority figure with e-mail feedback, (c) non-authority figure with face-to-face feedback, and (d) non-authority figure with e-mail feedback. Results showed that while both feedback delivery methods resulted in high performance with the presence of an authority figure, only face-to-face feedback resulted in high performance with a non-authority figure. Practical considerations for effective feedback delivery methods in relation to authority figures are also discussed.  相似文献

Drawing on a qualitative exploratory study of the gambling narratives of a group of Chinese men with problem gambling in Hong Kong, this paper proposes an alternative understanding of problem gambling. Rather than identifying problem gambling as a personal deficit or pathology, a narrative analysis of these Chinese men's gambling stories reveals their existential yearnings behind problem gambling. Told from the perspectives of these men, their gambling narratives invite us as researchers and practitioners to explore the meanings gamblers ascribe to gambling which they derived from the interplay between the socioeconomic and cultural ethos of the society and their personal histories. This offers us new insights into their motivations of gambling. As an attempt to fill the methodological gap in gambling studies, this paper also shows how an in-depth narrative research method can contribute to expanding our understanding of problem gambling beyond pathology.  相似文献

ABSTRACT

Evidence of direct and indirect effects of interparental relationship quality and parental contexts on child behavior problems is well established. However, limited literature exists about these associations in low-income, Black families in which the parents are not married. Informed by the risk and resilience theoretical perspective, this study hypothesized that disharmonious interparental relations would predict greater preschool child behavior problems directly and indirectly through maternal parenting factors and father contact. Economic difficulties and low maternal education would exacerbate these problems. This study included 2,115 Black, single mothers from Waves 1–3 of the Fragile Families and Child Wellbeing Study data sets. Using structural equation modeling, a strong model fit indicated that our hypotheses were supported. Discussion includes policy and practice implications related to the Healthy Marriage Initiative.  相似文献

The purpose of this study was to examine the longitudinal effects of parental monitoring and self-control on depression. To address this purpose, this study investigated the interrelationships among depression, perceived parental monitoring, and self-control—as well as their developmental changes from the eighth to the twelfth grades—by repeated assessment of 3449 Korean adolescents. The data from Korea Youth Panel Survey (KYPS) of the eighth graders who were followed for five years were analyzed using latent growth modeling. The univariate latent growth models showed that adolescents experience an increase in both parental monitoring and self-control but a decline in depression over the five years. In addition, the multivariate latent growth model suggested that the initial level of parental monitoring had significant effects, both directly and indirectly through self-control, on the initial level of depression. The linear changes in parental monitoring were associated with the linear changes in self-control; likewise, the linear changes in self-control were related to those in depression. These results imply that parental monitoring and self-control need to be emphasized as a strategy in order to prevent or alleviate adolescents' depression.  相似文献

This study investigated college students’ perception of the monetary value of career counseling services by using the contingent valuation method. The results of a multivariate survival analysis based on interviews with a convenience sample of 291 undergraduate students in South Korea indicate that, on average, participants’ expressed willingness to pay (WTP) for such services ranged from U.S. $10.22 to $10.54 per hour of individual career counseling. Self‐stigma and attitudes toward counseling had positive effects on their WTP, whereas the year in college and social stigma had negative effects. The results provide policy makers with preliminary evidence of the monetary value of career counseling.  相似文献
