Research in the past decade suggests that a persistent achievement gap between students from low-income minority backgrounds and higher-income white backgrounds may be rooted in theories of student motivation and youth purpose. Yet limited research exists regarding the role of purpose on positive youth development as it pertains to academic achievement. Using a sample of 209 high school students, this study examines the effectiveness of an intervention designed to promote purpose development and internal control over academic success in high school students from a low-socioeconomic-status community. Findings reveal that a short-term intervention was effective in significantly increasing internal control over academic success and purpose in life for students participating in the intervention group. In addition, analysis of academic achievement for students who experienced positive gains in internal control and purpose demonstrates significant gains in academic achievement as measured by grade point average. Implications are made for further study of internal control and life purpose as a means of academic intervention in the effort to address the achievement gap.  相似文献

Despite high rates of nonmarital childbearing in the U.S., little is known about the health of women who have nonmarital births. We use data from the NLSY79 to examine differences in age 40 self-assessed health between women who had a premarital birth and those whose first birth occurred within marriage. We then differentiate women with a premarital first birth according to their subsequent union histories and estimate the effect of marrying or cohabiting versus remaining never-married on midlife self-assessed health, paying particular attention to the paternity status of the mother's partner and the stability of marital unions. To partially address selection bias, we employ multivariate propensity score techniques. Results suggest that premarital childbearing is negatively associated with midlife health for white and black (but not Hispanic) women. We find no evidence that these negative health consequences of nonmarital childbearing are mitigated by either marriage or cohabitation for black women. For other women, only enduring marriage to the biological father is associated with better health than remaining unpartnered.  相似文献

Economically disadvantaged mothers face numerous barriers to stable, quality employment opportunities. One barrier that has received limited attention in previous research is having a child with significant psychological or behavioral problems. Using a representative sample of low‐income mothers and early adolescent children from the Three‐City Study (N = 717), we assessed whether adolescents' behavior problems prospectively predicted mothers' employment status, consistency, and quality. Lagged random‐effects regression models suggested that adolescents' psychological distress and delinquency inhibited the labor market success of disadvantaged mothers, although school problems were related to greater work effort among mothers. Links between labor market success and both psychological distress and delinquency differed across mothers with male and female adolescents.  相似文献

Various aspects of social learning and self-control theories have been applied to partner violence among multiple samples in the United States, but these theoretical approaches have been less commonly studied cross-culturally. Consequently, childhood maltreatment and low self-control have been identified as risk factors for various outcomes in primarily American samples. This study examined the relationships between childhood maltreatment, low self-control, and dating violence among college students in South Korea and the United States. Findings indicated that experiencing childhood maltreatment and having low self-control were key predictors of perpetration and victimization for both psychological and physical relationship violence. Witnessing interparental violence during childhood was less consistently predictive of one's involvement in a violent dating relationship. Implications for theory and policy are discussed.  相似文献

We present theoretical arguments and empirical research to suggest that the principal mechanisms of cumulative causation do not function in large urban settings. Using data from the Mexican Migration Project, we found evidence of cumulative causation in small cities, rural towns and villages, but not in large urban areas. With event-history models, we found little positive effect of community-level social capital and a strong deterrent effect of urban labor markets on the likelihood of first and later U.S. trips for residents of urban areas in Mexico, suggesting that the social process of migration from urban areas is distinct from that in the more widely studied rural migrant-sending communities of Mexico.  相似文献

Couple childbearing desires, intentions, and births   总被引:1,自引:0,他引:1  
Using new panel data from the National Surveys of Families and Households, I investigate the effects of wives’ and husbands’ childbearing desires on their spouses’ intentions, and the effects of spouses’ desires and intentions on subsequent births. The results show clearly that husbands’ desires and intentions influence couples’ births, with approximately equal force to that of wives’ desires and intentions. When couples disagreed about wanting a child, each partners’ intentions were shifted toward not having a child; and disagreement in desires or intentions were reflected in birth rates that were lower than average. These patterns were generally not different for couples with more or less traditional gender roles or attitudes.  相似文献

ABSTRACT

This paper explores Indigenous (im)mobilities in the Anthropocene, and their relationship to Pacific Islands climate activism. In a context where Indigenous peoples and perspectives are poorly represented in global climate politics, it is important to understand how Pacific people represent their own interests and imagine their own futures as pressures to move due to climate change take hold. We examine political action outside of formal governance spaces and processes, in order to understand how Indigenous people are challenging state-centric approaches to climate change adaptation. We do so by studying the works of Pacific activists and artists who engage with climate change. We find that *banua – an expansive concept, inclusive of people and their place, attentive to both mobility and immobility, and distributed across the Pacific Islands region – is essential for the existential security of Pacific people and central to contemporary climate activism. We find that Pacific activists/artists are challenging the status quo by invoking *banua. In doing so, they are politicising (im)mobility. These mobilisations are coalescing into an Oceanic cosmopolitanism that confronts two mutually reinforcing features of contemporary global climate politics: the subordination of Indigenous peoples, perspectives and worldviews; and the marginalisation of (im)mobility concerns within the global climate agenda.  相似文献

This paper uses an implicit contracting framework to understand the dynamic nature of divorce settlements and to analyze the determinants of noncompliance with child support awards. In addition to the standard economic variables that affect the noncustodial parent’s (NCP’s) ability to pay child support, our approach focuses on factors that may affect the NCP’s desire to pay, such as the ongoing relationship between the two parents and between the NCP and the children. We also examine the “state-contingent” nature of child support payments and explore the factors that lead to modifications in child support agreements. Using a longitudinal data set collected by the Stanford Child Custody Project, the empirical analysis provides documentation that compliance by noncustodial fathers can vary substantially from month to month. In addition, we find that even within a short period after divorce, a substantial minority of parents agree to make informal modifications to their divorce settlement in response to changes in economic circumstances and in custodial arrangements  相似文献

Paradox lost: Explaining the hispanic adult mortality advantage   总被引:1,自引:0,他引:1  
Palloni A  Arias E 《Demography》2004,41(3):385-415
We tested three competing hypotheses regarding the adult "Hispanic mortality paradox": data artifact, migration, and cultural or social buffering effects. On the basis of a series of parametric hazard models estimated on nine years of mortality follow-up data, our results suggest that the "Hispanic" mortality advantage is a feature found only among foreign-born Mexicans and foreign-born Hispanics other than Cubans or Puerto Ricans. Our analysis suggests that the foreign-born Mexican advantage can be attributed to return migration, or the "salmon-bias" effect. However, we were unable to account for the mortality advantage observed among other foreign-born Hispanics.  相似文献
