Persons who were perceived to be Arabs experienced a period of increased harassment, violence, and workplace discrimination in the United States in the weeks immediately following September 11, 2001. Drawing on prior studies that have hypothesized that experiences of discrimination increase the risk of preterm birth and low birth weight, this study explores whether there was an effect on birth outcomes for pregnant women of Arab descent. California birth certificate data are used to determine the relative risk of poor birth outcomes by race, ethnicity, and nativity for women who gave birth in the six months following September 2001, compared with the same six calendar months one year earlier. The relative risk of poor birth outcomes was significantly elevated for Arabic-named women and not for any of the other groups. 相似文献

This study investigated potential heterogeneity in development among offspring (age 17) of teen mothers and maternal life course as correlates of variation. Using latent class analysis, subgroups of developmental outcomes were identified. Maternal standing in two life course realms (i.e., socioeconomic and domestic) was considered as a potential explanation for heterogeneity in offspring's development. Offspring reported on measures assessing their psychological, academic, and behavioral development. Teen mothers reported on measures of life course realms. Three subgroups of developmental outcomes were identified: on track (52%), at risk (37%), and troubled (11%). Findings suggest that economic hardship and number of pregnancies among teen mothers distinguish developmental patterns among teenage offspring, whereas teen mothers' educational attainment and marital status do not. 相似文献

Gay and bisexual men are at disproportionate risk for human immunodeficiency virus (HIV) infection. While prevention efforts often emphasize consistent condom use, there is growing evidence that men are using seroadaptive safer-sex strategies, such as serosorting and seropositioning. This qualitative analysis of 204 HIV-negative and HIV-positive gay and bisexual men explored the ways that a sexual partner’s HIV status can influence safer-sex strategies and sexual decisions. The majority of the respondents reported that they were influenced by their partners’ HIV status. Those respondents who reported no influence discussed adhering to safer-sex rules that were not dependent on partner status and a lack of concern about HIV. Conversely, respondents who reported influence identified three primary areas of influence: psychological impacts, partner preference and selection, and specific behavioral intentions and strategies. A conceptual model explicating a potential process by which respondents use partner serostatus information in shaping sexual decisions is presented. 相似文献

In U.S. social welfare history, many have suggested that if benefits were too attractive, consumers would come out of the woodwork to take advantage of the opportunity. Clinical trials have provided evidence of the woodwork effect’s existence, suggesting caution when expanding home- and community-based services (HCBS). However, it is unclear whether these studies are best suited to assess whether a system-level effect occurs. Using state and federal data tracking Ohio’s long-term services and support (LTSS) system from 1995 to 2015, this paper examines changes in the utilization rates and expenditures of Medicaid LTSS to explore whether a woodwork effect occurred as Ohio moved to improve its LTSS system balance (80% Nursing Home [NH], 20% HCBS) to (49% Nursing Home [NH], 51% HCBS). After accounting for population growth of individuals older than 60 and those with two or more impairments in activities of daily living, there was no change in utilization rates of older people with severe disability (1995: 491 per 1000 population, 2015: 495 per 1000 population) or overall LTSS expenditures (1997: $2.7 million [in 2013 dollars], 2013: $2.9 million). Our results suggest that states can make significant strides in HCBS expansion without increasing the overall long-term services utilization rate. 相似文献

Adopting a procedure developed with human speakers, we examined infants' ability to follow a nonhuman agent's gaze direction and subsequently to use its gaze to learn new words. When a programmable robot acted as the speaker (Experiment 1), infants followed its gaze toward the word referent whether or not it coincided with their own focus of attention, but failed to learn a new word. When the speaker was human, infants correctly mapped the words (Experiment 2). Furthermore, when the robot interacted contingently, this did not facilitate infants' word mapping (Experiment 3). These findings suggest that gaze following upon hearing a novel word is not sufficient to learn the referent of the word when the speaker is nonhuman. 相似文献

This qualitative study explores racial identity development of teacher candidates during a teacher preparation program dedicated to preparing teachers for diverse classrooms. Two black teacher candidates in the US demonstrate their racial identity development through critical reflections offered throughout the program. Findings suggest that teachers’ racial identities shaped their constructions of culturally relevant (CR) pedagogy. Implications for teacher education programs include considering how the development of CR pedagogues is influenced by teacher candidates’ racial identities and experiences. 相似文献

Simple linear combinations of forecasts have consistently been found to be more accurate than individual forecasts. Several recent studies have found that combination forecasts derived by constrained or unconstrained multiple regression are more accurate than a simple average of individual forecasts. This study uses macroeconomic data to compare the accuracy of combination forecasts derived by a Bayesian methodology with the accuracy of composite forecasts derived by multiple regression. Using the forecasts of four macroeconomic variables from five well-known econometric models, the study finds that the Bayesian combination procedure produces more accurate composite forecasts than does the regression combination procedure, based on a version of Theil's U2 statistic. 相似文献
