This paper provides an in-depth examination of the joint effects of race/ethnicity and immigrant status on adolescents’ intercourse risk. We employ a sample of 4,535 females and 3,759 males from the National Education Longitudinal Study (NELS 88/94) who were followed for 6 years beginning in the eighth grade. We use discrete-time logistic regression models to estimate the associations of race/ethnicity and immigrant generational status with first intercourse hazard, and to evaluate the statistical interactions between race/ethnicity and immigrant status. Overall, Asian and Hispanic girls had lower and non-Hispanic Black girls had higher estimated risks relative to non-Hispanic White girls. Hispanic boys and White non-Hispanic boys had similar intercourse risks, but Black boys had higher and Asian boys lower relative risks. However, these patterns are contingent on immigrant status. Among girls, the protective effects of Asian or Hispanic identity are found only among second generation youth. Risk profiles for boys are more complex: being a third-plus generation Hispanic is associated with a higher risk while an Asian identity is associated with a lower risk only among first- and second-generation youth. These findings confirm the importance of accounting for the overlap between race/ethnicity and immigrant status in models of adolescent behavior. As the demographic diversity of the US population grows, researchers must include both race/ethnicity and immigrant status in their models of adolescent behavior.  相似文献

This article contrasts the earnings of high‐ and low‐status care workers in Canada, the United States, Japan, the Republic of Korea and Taiwan (China) using the micro‐data files of the Luxembourg Income Study. By disaggregating existing definitions of care work, the author identifies occupations with lower and higher degrees of “social closure”, revealing the associated care penalties and care bonuses cross‐nationally. She also empirically measures the extent of similarities (and differences) between and within care economies in “liberal” and “productivist developmental” welfare regimes, offering support for the argument that globalization has fostered substantial convergence within the international care market.  相似文献

Intergroup dialogue is a method of social justice education. Most intergroup dialogue research explores race and gender identities. Sexual orientation dialogues are uncommon and not yet examined empirically. This qualitative study explores sexual orientation dialogue courses from the perspective of lesbian, gay, and bisexual (LGB) student participants. Understanding target, or marginalized, group perspective of planned intergroup experiences is important given concerns raised in the literature. We document student motivations for participating in dialogues, core outcomes, and main challenges that arose in dialogue. Core outcomes include learning about and accepting one's sexual identity and empowerment. Challenges include those stemming from invisibility of sexual orientation identity. Recommendations are made for intergroup dialogue practice and research.  相似文献

Features of the habituation paradigm were combined with the visual expectation paradigm to examine behavioral and cortical indexes of infants' visual expectations. Eight 3‐month‐old infants watched an alternating picture sequence while their eye movements were videotaped and their cortical electrophysiological activity (event‐related potential [ERP]) was recorded. Two ERP epochs were examined: a 3,000‐msec stimulus‐locked epoch included 1,000 msec before stimulus onset through 1,000 msec after stimulus offset; and a 1,200‐msec response‐locked epoch included 700 msec before saccade onset through 500 msec after the saccade. All infants anticipated upcoming pictures, and eye movement latencies for pictures that were not anticipated were comparable to saccade latencies reported in other visual expectation studies of infants at this age. Three components were identified in the stimulus‐locked ERP waveform: a slowly developing negativity prior to picture onset, a postonset negative slow wave, and a late negative deflection that peaked about 750 msec after picture onset. All stimulus‐locked components were larger for familiar than for unfamiliar pictures; prestimulus negativity was also greater before anticipated pictures. The response‐locked waveform contained 2 prominent features: a slowly increasing negative shift (NS) that began about 500 msec before saccade onset and a positive presaccadic potential that occurred about 30 to 90 msec before the saccade. Response‐locked components were larger for anticipatory saccades at the frontal scalp site; for reactive saccades, response‐locked components were larger at the vertex. Results are informative about ERPs in infants, cortical control of eye movements, and the development of visual expectations.  相似文献

Concepts of “adaptive context” and “holding environment” serve as a foundation from which to address the impact of typical outpatient psychotherapy clinic settings on the process of psychoanalytic therapy. Issues of transference and resistance, treatment boundaries, professional investment, and the patients' and therapists' perceptions of the therapy process are primary areas of consideration. The depth, intensity, and power of psychoanalytically-oriented psychotherapy is seen as potentially limited by the structure and policies to which clinic settings tend to adhere. Circumstances in private practice are used as a point of comparison and suggestions are made to minimize treatment complications.  相似文献

Throughout the U.S., high visibility drug markets are concentrated in neighborhoods with few economic opportunities, while drug buyers/users are widely dispersed. A study of Pittsburgh Syringe Exchange participants provides data on travel between and network linkages across neighborhoods with different levels of drug activity. There are distinct racial patterns to syringe distribution activity within networks and across neighborhoods. Pittsburgh's history suggests that these patterns emerge from historical patterns of social and economic development. Study data demonstrate the ability of IDUs to form long-term social ties across racial and geographic boundaries and use them to reduce the risk of HIV transmission.  相似文献
