Prior research showed that 5‐ to 13‐month‐old infants of chronically depressed mothers did not learn to associate a segment of infant‐directed speech produced by their own mothers or an unfamiliar nondepressed mother with a smiling female face, but showed better‐than‐normal learning when a segment of infant‐directed speech produced by an unfamiliar nondepressed father signaled the face. Here, learning in response to an unfamiliar nondepressed father’s infant‐directed speech was studied as a function both of the mother’s depression and marital status, a proxy measure of father involvement. Infants of unmarried mothers on average did not show significant learning in response to the unfamiliar nondepressed father’s infant‐directed speech. Infants of married mothers showed significant learning in response to male infant‐directed speech, and infants of depressed, married mothers showed significantly stronger learning in response to that stimulus than did infants of nondepressed, married mothers. Several ways in which father involvement may positively or negatively affect infant responsiveness to male infant‐directed speech are discussed.  相似文献

This article reports on a study of 503 African-American, Hispanic, and White non-Hispanic adolescent girls attending public schools in Miami, Florida, The primary objectives of the study were to determine the prevalence of 13 self-reported delinquent behaviors in the sample, to compare these rates among the three groups of students, and to explore the predictive influences of several family factors that correlate with delinquency. It was found that 37.5% of the sample engaged in one or more acts of serious delinquency, with African-Americans reporting they had engaged in significantly more of these behaviors. The best predictors of theft/vandalism were low family pride and family substance abuse for Hispanics, low family communication for African-Americans, and low family pride for White non-Hispanics. The findings indicate that traditional family factors that have been used repeatedly to understand delinquency by male adolescents were not strong predictors of delinquency among the adolescent girls in the sample.  相似文献

Objective: Pain affects a significant proportion of college students in the United States and has been linked to anxiety and depressive symptoms. Rumination and worry, two transdiagnostic factors linked to comorbidity, may explain the relationship between pain and mental health symptoms.

Current Study: The current study examined worry and rumination as explanatory factors in the relationship between pain and anxiety and depressive symptoms in a sample of college students with pain (n?=?1,577; 79.9% female).

Results: Results indicated that both rumination and worry explained the relationship between pain and depressive and social anxiety symptoms, while rumination alone explained the relationship between pain and anxious arousal symptoms.

Conclusion: The current study provides novel empirical evidence that worry and rumination each help explain the relationship between pain and anxiety and depressive symptoms among college students with current pain, and college students in pain may benefit from targeted psychosocial strategies aimed at decreasing worry and ruminative responses.  相似文献

ABSTRACT

The study documents opinions about the police among black and Latino youth and explores how these assessments reflect differences in lived experiences and frames of interpretation of police encounters across gender and race/ethnicity. This specification is important to better understand how youth navigate interactions with law enforcement and how discrete experiences are interpreted in the context of other contacts of racial and gender inequality. We draw on interviews with 43 black and Latino youth, ages 13–21, compiled as part of a project on police stops in New York City. Although our findings indicate that youth tend to see the police negatively, we note considerable heterogeneity, with Latinos/as conveying more mixed views of law enforcement and females signaling more negative perceptions. We tie these differences to variation in the type, volume, and quality of encounters with the police, as well as the saliency of direct and indirect experiences.  相似文献

We report data concerning cross-cultural judgments of emotion in spontaneously produced facial expressions. Americans, Japanese, British, and International Students in the US reliably attributed emotions to the expressions of Olympic judo athletes at the end of a match for a medal, and at two times during the subsequent medal ceremonies. There were some observer culture differences in absolute attribution agreement rates, but high cross-cultural agreement in differences in attribution rates across expressions (relative agreement rates). Moreover, we operationalized signal clarity and demonstrated that it was associated with agreement rates similarly in all cultures. Finally, we obtained judgments of won-lost match outcomes and medal finish, and demonstrated that the emotion judgments were associated with accuracy in judgments of outcomes. These findings demonstrated that members of different cultures reliably judge spontaneously expressed emotions, and that across observer cultures, lower absolute agreement rates are related to noise produced by non-emotional facial behaviors. Also, the findings suggested that observers of different cultures utilize the same facial cues when judging emotions, and that the signal value of facial expressions is similar across cultures.  相似文献

This article is aimed at reviewing a novel Bayesian approach to handle inference and estimation in the class of generalized nonlinear models. These models include some of the main techniques of statistical methodology, namely generalized linear models and parametric nonlinear regression. In addition, this proposal extends to methods for the systematic treatment of variation that is not explicitly predicted within the model, through the inclusion of random effects, and takes into account the modeling of dispersion parameters in the class of two-parameter exponential family. The methodology is based on the implementation of a two-stage algorithm that induces a hybrid approach based on numerical methods for approximating the likelihood to a normal density using a Taylor linearization around the values of current parameters in an MCMC routine.  相似文献

Summary Important demographic changes have been taking place in Spainduring the last two decades as a result of immigration. Dueto an ever-increasing multicultural spread, social work professionalsare faced with the new challenge of providing quality servicesto diverse ethnic populations. After briefly describing themain characteristics of immigration in Spain, their implicationsfor the provision of social services and the need to providemulticultural training for social workers are analysed. Theconceptual framework proposed addresses some of the main variablesthat professionals working with these minorities should takeinto account, emphasizing: culture; language; family support;community resources; clients' explanatory model of the problems;provision of services for multiple problems; ethnic discrimination;and assessment instruments. Some key points for multiculturaltraining in this field are discussed, paying special attentionto the need to develop culturally sensitive and bias-free diagnostictools; accreditation and funding of professional programmes;and cross-cultural competence training. The main contents andobjectives of a multicultural training course for social workersare described.  相似文献

This paper examines the efficient estimation of partially identified models defined by moment inequalities that are convex in the parameter of interest. In such a setting, the identified set is itself convex and hence fully characterized by its support function. We provide conditions under which, despite being an infinite dimensional parameter, the support function admits √n‐consistent regular estimators. A semiparametric efficiency bound is then derived for its estimation, and it is shown that any regular estimator attaining it must also minimize a wide class of asymptotic loss functions. In addition, we show that the “plug‐in” estimator is efficient, and devise a consistent bootstrap procedure for estimating its limiting distribution. The setting we examine is related to an incomplete linear model studied in Beresteanu and Molinari (2008) and Bontemps, Magnac, and Maurin (2012), which further enables us to establish the semiparametric efficiency of their proposed estimators for that problem.  相似文献
