This study explores the determinants of labor supply patterns among Latinas in the USA. We use recent microeconomic data from the Panel Study on Income Dynamics/Latino National Political Survey (PSID-LNPS) to estimate models of labor force participation, wages, and hours worked for a sample of Cuban, Mexican, and Puerto Rican women. We estimate the same models for Anglo and Black women in order to explore ethnic differences in the impact of characteristics affecting both the reservation and the market wage. We find that differences exist in the return to characteristics, such as education, but that there are also substantial differences in the levels of those characteristics across ethnic groups. The low wage rates and labor market activity of Latinas relative to Anglo and Black women are thus likely to be the combined result of lower investments in human capital and larger family size, the greater negative impact of macroeconomic conditions, and a stronger responsiveness to wages. Among Latinas, we find that there are differences in labor market outcomes between national origin and nativity groups. We also find that age at arrival and years in the USA play a role in labor supply, and that this is particularly true for Puerto Rican women.  相似文献

Employer use of employee drugscreening procedures is widespread in the U.S. A state-by-state analysis of statutory law applicable to the drug testing issue is combined with state and industry data to isolate how drug testing laws affect workplace injury rates. Based on our data, injury rates are not statistically related to the state’s legal environment.  相似文献

The 1995 wave of the Add Health study is used to investigate the relative influence of parent gender and residence on patterns of parental involvement with adolescents. Adolescent reports (N =17,330) of shared activities, shared communication, and relationship quality with both biological parents are utilized. A multidimensional scaling analysis reveals that parent gender explains most of the variance in parent‐adolescent involvement, with residential status playing a secondary yet a fundamental role in accounting for these patterns. Resident mothers who do not live with adolescents’ biological fathers engage in the broadest range of activities with their children. Unpartnered resident fathers display patterns of parenting that are as similar to mothers as they are to other fathers.  相似文献

We examine the relationship between neighborhood structural characteristics, social organization, and the sexual partnering practices of adults. Analyses of 1990 census and 1995–1997 survey‐based data on Chicago neighborhoods and adult sexual activity reveal for men a number of neighborhood influences on sexual partnering practices. First, residential stability is negatively associated with having a short‐term sexual partner in the last year. Second, neighborhood social ties are positively associated with short‐term sexual partnering in neighborhoods with low levels of collective efficacy—the combination of cohesion and shared expectations for beneficial action among neighbors—but this effect is substantially reduced as collective efficacy increases. Moreover, neighborhood collective efficacy and social ties mediate the effect of residential stability on sexual partnering practices. Neighborhood characteristics were not associated with short‐term sexual partnering for women.  相似文献

Communication technology is a central feature of young people's lives, but its role in romantic and sexual relationships has not been thoroughly examined. This article describes how young adults use communication technology for partnering across relationship stages (formation, maintenance, and dissolution) and types (serious/casual), and proposes implications of usage in relationships. This study analyzed qualitative data from a five-week, prospective, coital diary method with related debriefing interviews (N = 70) of African American and Puerto Rican men and women aged 18 to 25 years in Hartford and Philadelphia. Cell phones, including calls, text messaging, and mobile Internet, were the most common forms of communication technology used for partnering goals. Participants reported using cell phones to pursue partnering goals across all relationship stages, including formation (meeting, screening, and getting to know new partners), maintaining existing relationships, and breaking up. Cell phone uses depended on the type of relationship (serious/casual) and the participants' intentions and desires. Results indicated that cell phones are an important element of communication among young adults in romantic and sexual relationships. Specific features of cell phone communication shape the process and context of partnering. Future research should explore emerging communication technologies and implications for psychosocial development, dating violence, and sexual behavior.  相似文献

Marital satisfaction has been psychometrically measured using many different instruments not soundly based on theory. The Revised Dyadic Adjustment Scale (RDAS), consisting of 14 items, is commonly accepted by researchers and practitioners to measure marital satisfaction but was not specifically designed to measure marital satisfaction. The Satisfaction with Married Life Scale (SWML), consisting of five items, is a short scale specifically targeted toward measuring marital satisfaction. An online sample collected from 1,187 couples throughout the United States was used to compare these instruments' correlation (r = .782), factor structures, reliability (SWML, α = .958; RDAS, α = .943), theoretical foundation, and validity. These instruments are on parity with each other when measuring marital satisfaction; however, each instrument yields implications for practitioners and researchers desiring to measure marital satisfaction.  相似文献

This paper uses data from the 2004 General Social Survey to examine the relationship between religious belief and practice (religiosity), spirituality, social support, and health status. Health status is conceptualized first in terms of a subjective assessment and, second, as two objective indicators of physical problems. These relationships were examined first within the total GSS sample, and then separately for respondents who reported below or above the median annual income. Results indicate that spirituality is a positive predictor of respondents’ subjective assessment of their health in the overall sample, but not in either separate income group. Social support does not predict positive subjective or objective health outcomes in the entire sample or for any income group. However, religiosity is a positive predictor of physical health, but only for the most severe of the physical health problems measured, and only for respondents whose annual income is below the national median. Thus, it appears that religiosity is a health resource for those below average income.  相似文献
