In this study, we draw on longitudinal, state‐level data to analyze the impact of four distinct forms of school racial segregation on black/white achievement gaps in math and reading. Pooled time‐series analyses with two‐way fixed effects suggest that increases in black–white dissimilarity and black student isolation contribute to black/white achievement gaps, increases in black–white exposure reduce achievement gaps, and increases in exposure of black students to other minority students have no impact. We conclude by discussing the implications of school racial segregation as a source of academic achievement disparities between black and white students in the contemporary United States.  相似文献

Since the eighteenth century, anti-slavery and antiracist activists of African descent across the Atlantic world have sought to establish a connection with Africa. The great American abolitionist Frederick Douglass resisted those trends. Douglass self-identified as a citizen of the USA and rejected all arguments that African-Americans had any racial, national or spiritual connection with African peoples. This article situates the roots of Douglass' position within his long fight against various schemes for colonization and emigration. It concludes that Douglass rejected those plans not only because he believed they distracted from the struggle against slavery in the USA, but also because he was convinced that Anglo-American civilization provided far greater opportunities for individual and collective betterment than relocation to Africa.  相似文献

This article discusses some of the reasons why social workers need to add to their understanding of the law and legal procedures, and to develop legal skills. It also explores several specific areas of the law to be studied: function, sources, concepts, procedures, and skills. A teaching approach to this material in an introductory course on law for social workers is then presented. The article concludes with suggestions for additional curriculum offerings.  相似文献

ABSTRACT

The family stress model delineates the connections between economic hardship, economic pressure, marital interactions, marital quality, and, finally, marital instability. This study evaluated the family stress model in a sample of 661 remarried couples using structural equation modeling. The model was evaluated both within and between spouses. Consistent with the family stress model, marital instability and quality were influenced by economic hardship and pressure through decreased spousal warmth and increased spousal hostility. Implications for remarriage education and counseling are discussed.  相似文献

ABSTRACT

The study examined a new child report measure of maternal support following child sexual abuse. One hundred and forty-six mother–child dyads presenting for a forensic evaluation completed assessments including standardized measures of adjustment. Child participants also responded to 32 items considered for inclusion in a new measure, the Maternal Support Questionnaire–Child Report (MSQ-CR). Exploratory factor analysis of the Maternal Support Questionnaire–Child Report resulted in a three factor, 20-item solution: Emotional Support (9 items), Skeptical Preoccupation (5 items), and Protection/Retaliation (6 items). Each factor demonstrated adequate internal consistency. Construct and concurrent validity of the new measure were supported in comparison to other trauma-specific measures. The Maternal Support Questionnaire–Child Report demonstrated sound psychometric properties. Future research is needed to determine whether the Maternal Support Questionnaire–Child Report provides a more sensitive approximation of maternal support following disclosure of sexual abuse, relative to measures of global parent–child relations and to contextualize discrepancies between mother and child ratings of maternal support.  相似文献

This paper reviews Australian classification practices for commercial video games that contain simulated gambling. In the last decade, over 100 video games featuring gambling simulations have been classified as suitable for commercial sale to youth in Australia, with 69 of these video games rated ‘PG’ for Parental Guidance Recommended (i.e. suitable for ages 8+years) and the remaining 33 rated ‘G’ for General (i.e. suitable for all ages). A review of the literature suggests that consumer advice and warnings related to video game material are often inconsistent and/or not adequately provided. A public health approach suggests that the presence of gambling content in video games may present risks to younger players unfamiliar with how gambling operates. It is argued that there is a need for further academic debate on social responsibility issues of early childhood and adolescent exposure to, and involvement in, simulated gambling activities available in interactive gaming technologies.  相似文献

ABSTRACT

This research piloted an e-health intervention that used social media to friendsource peer support for Alzheimer’s disease (AD) caregivers. Friendsourcing is a variant of crowdsourcing. Crowdsourcing recruits online participants who share a characteristic that makes their volunteerism meaningful when they join to achieve an outcome. Friendsourcing recruits online participants who share membership in a social network that makes their volunteerism meaningful when they join to achieve an outcome. This article introduces our friendsourcing intervention research and examines the effects on the psychological well-being of AD caregivers. After a 6-week intervention, caregivers were found to have significantly decreased burden (Z?=??2.01, p?<?.05) and perceived stress (Z?=??2.95, p?<?.01). Emotional and informational support scores were significantly increased (Z?=??2.32, p?<?.05). Qualitative data analysis of the intervention identified positive effects in new caregiving knowledge acquisition and application and reduced stress in the acceptance of the caregiving role. Joining social networks in support groups through friendsourcing was feasible for AD caregivers who were familiar with social media, and can provide another means of guiding the development of their personal support networks.  相似文献

Altogether, 2,196 students from 29 Austrian universities took part in an empirical investigation on learning and communication in e-learning courses. The students completed a questionnaire on their experiences in an actual e-learning course, on their perceived learning achievements, and their enjoyment of the course. Furthermore, they expressed their preferences for online or face-to-face communication. All in all, students were satisfied with their course. They did not prefer one communication setting over another. They preferred online-communication for the distribution of information but advocated face-to-face communication when joint learning and cooperation are important or when socio-emotional relations are to be developed. The results of the study advocate blended-learning designs and give recommendations for which communication purposes online and for which face-to-face settings are more adequate.  相似文献
