Since 1983, the focus of the Rutgers Alcohol and Other Drug Assistance Program (ADAP) has been developing policies, training staff to identify students at risk, developing and implementing evidence-based screening and brief interventions, providing short-term counseling by professionals trained in alcohol and other drug abuse to assist students beyond brief interventions, identifying effective treatment for college students, developing a campus recovery program, on-campus recovery housing, and other supports for students in recovery. This article presents a case study of the Rutgers ADAP program, of building and sustaining a program committed to engaging students in both evidence-based risk reduction interventions and an on-campus recovery community given their stage of change and motivation to make changes. Historical milestones are described as part of a creative model for intervention. We identify the challenges of integrating substance abuse recovery into campus mental health programs, and of integrating recovery into other university communities.  相似文献

This paper examines whether receipt of public or private assistance is associated with recipients’ own generosity in the form of formal and informal volunteering. Using matched data from the 2007–2011 American Time Use Survey and the Annual Social and Economic Supplement to the Current Population Survey, this paper finds that receipt of private assistance from friends and relatives is negatively associated with the time women spend caring for non-household adults and the time men spend caring for non-household children. Receipt of public assistance is found to be negatively associated with men’s care of non-household adults. No associations are found between either type of assistance and time spent volunteering for a formal organization.  相似文献

The inclusion of technology in the classroom is an increasingly important feature of effective instruction. The implementation of Common Core Standards in many states also requires teachers to consider new pedagogical strategies to support meaningful learning. This article explores the intersection between technology demands and curricular change by examining apps that can be used to support Common Core State Standards instruction in history/social studies. Specifically, the authors highlight several apps that they presented at a professional development workshop for six to twelve history/social studies teachers and discuss the teachers' feedback regarding the strengths and limitations of apps to support their instruction. Conclusions are drawn and recommendations for history/social studies teachers using apps in the classroom are provided.  相似文献

This paper analyzes the effect of a statewide merit-based scholarship program on educational outcomes in Arizona. It tests whether Arizona’s Instrument to Measure Standards (AIMS) scholarship has an effect on a comprehensive set of educational outcomes such as the number of applicants, student admissions, first-year first-time enrollment, ACT scores of entering freshman, retention rates, as well as on the level of tuition and fees at the three schools targeted by the program; Arizona State University, University of Arizona and Northern Arizona University. Both difference-in-differences estimation as well as synthetic control methods shows that AIMS has an economically and statistically significant effect enrollment. Enrollment effects are greatest among African American and Hispanic students and are significant for both men and women. While point estimates suggest that AIMS also lead to increases in tuition and fees, these results are not robust to placebo tests.  相似文献

The probability that Mexican households receive remittances increases in response to temporary loss of employment by household heads. Evidence indicates that the probability doubles in the short-term, with a stronger effect in the first quarter of unemployment. Taking into account inter-household transfers within Mexico, the increase in the probability of private transfers is similar in households with low and high access to migratory networks in the U. S. The effectiveness of private transfers as an insurance mechanism has been reduced in an environment of economic crisis.  相似文献

This study examined gender, age, and task differences in positive touch and physical proximity during mother–child and father–child conversations. Sixty-five Spanish mothers and fathers and their 4- (M = 53.50 months, SD = 3.54) and 6-year-old (M = 77.07 months, SD = 3.94) children participated in this study. Positive touch was examined during a play-related storytelling task and a reminiscence task (conversation about past emotions). Fathers touched their children positively more frequently during the play-related storytelling task than did mothers. Both mothers and fathers were in closer proximity to their 6-year-olds than their 4-year-olds. Mothers and fathers touched their children positively more frequently when reminiscing than when playing. Finally, 6-year-olds remained closer to their parents than did 4-year-olds. Implications of these findings for future research on children’s socioemotional development are discussed.  相似文献

Although appearance-based cues can help to diagnose physical illness, visual manifestations of mental disorder may be more elusive. Here, we investigated whether individuals could distinguish women with a serious mental disorder (borderline personality disorder) from demographically- and IQ-matched non-psychiatric controls. Participants rated mentally ill targets as more likely to have a mental disorder from photos more accurately than chance, despite not believing that such judgments were possible. The configuration of facial cues played an important role in these judgments, as interfering with the spatial relationships between facial features reduced participants’ accuracy to chance guessing. Further investigation showed similar results when participants rated the targets for specific mental disorders (borderline personality disorder, major depressive disorder) and rated the mentally ill targets as more depressed, angry, anxious, disgusted, emotionally unstable, distressed, and less happy. Moreover, the depression ratings significantly correlated with the targets’ actual depressive symptoms. Thus, individuals may be able to infer aspects of mental disorder from minimal facial cues.  相似文献

We assessed the impact of social context on the judgment of emotional facial expressions as a function of self-construal and decoding rules. German and Greek participants rated spontaneous emotional faces shown either alone or surrounded by other faces with congruent or incongruent facial expressions. Greek participants were higher in interdependence than German participants. In line with cultural decoding rules, Greek participants rated anger expressions less intensely and sad and disgust expressions more intensely. Social context affected the ratings by both groups in different ways. In the more interdependent culture (Greece) participants perceived anger least intensely when the group showed neutral expressions, whereas sadness expressions were rated as most intense in the absence of social context. In the independent culture (Germany) a group context (others expressing anger or happiness) additionally amplified the perception of angry and happy expressions. In line with the notion that these effects are mediated by more holistic processing linked to higher interdependence, this difference disappeared when we controlled for interdependence on the individual level. The findings confirm the usefulness of considering both country level and individual level factors when studying cultural differences.  相似文献

The purpose of this research was to examine a conceptual/theoretical model with negative (substance use) and positive (extracurricular activities) mediating factors between several bonding systems and violent behavior among female youth. Since much of the prior researches have focused on both males and females therefore this study is focusing on females only. Data from the 2011 National Survey on Drug Use and Health was used for this study. For the purpose of this study female research participants between the age of 12–17 were selected (N = 9383). At the stage of bivariate analysis, parental bonding system was omitted from a model before moving onto a structural equation modeling (SEM) analysis as most of the correlations between indicators of parental bonding systems and dependent variables were not significant. Revised model with two bonding systems on violent behavior through two mediating constructs, extracurricular activities and substance use were tested through the SEM and Sobel test analyses. This structural model specifies a satisfactory fit with the sample. Several mediating effects within this model, which help lower the occurrence of violent behavior, were also validated.  相似文献

This study is an assessment of different components of attachment for a sample of Romanian adoptees and their parents, both who participated in the project (n = 63). Results suggest that various aspects of the parent–child relationship in early adolescence is quite positive from both the adoptee and adoptive parent perspective. However, almost half (46 %) of the adoptees were assessed as having insecure attachment. There are differences between all components of parental attachment and adoptee attachment security. Also, insecure attachment is more likely to occur with less optimal parenting style. Implications for social work practice and research are discussed.  相似文献
