Group-based intervention on attention and executive functions in the school context

The objective of the study was to examine the effects of a group-based behavioural, cognitive and skills training intervention (Maltti) provided in schools for elementary school pupils with attention and executive function (EF) deficits. The treatment effects were identified by comparing an intervention group (n = 46) with a waitlist control group (n = 26). Specific effects of the intervention on behavioural deficits in attention and EF in a classroom setting as well as on academic skills were examined. Our analysis indicated that significant intervention effects could be found in the behavioural manifestation of attentional and executive skills in the classroom setting among children (n = 30) who were evaluated as having moderate symptoms in the pre-intervention assessment. Positive effects of the intervention were also observed in arithmetic and reading skills. The severity level of pre-intervention attention and EF deficits did not moderate the results observed in the academic skills tests. The results of this study suggest that a combination of behavioural, cognitive and skills training methods applied in a school context can be effective in reducing attention and EF problems and enhancing the academic performance of children with attention and EF deficits.     

Academic socialization,parental educational expectations,and academic self‐efficacy among Latino adolescents

This study examined the direct association between parental educational expectations and adolescents’ academic self‐efficacy, as well as the moderating influence of parental academic socialization messages. Participants were 148 Latino parent–adolescent dyads with the majority of Mexican origin (80.4%). Most of the parent participants were mothers (85.8%). Adolescents were 13 (46%) or 14 (54%) years of age, and 53% identified as female. Adolescents reported their academic self‐efficacy and perceptions of their parents’ educational expectations; parents reported on their academic socialization messages of shame/pressure and effort regarding academics. The results suggest that, after accounting for parents’ level of education and immigrant status, parental educational expectations were positively associated with adolescent academic self‐efficacy. This association was stronger among adolescents whose parents reported transmitting fewer messages of shame/pressure and academic effort. These results point to the importance of nuances in the content and type of academic socialization messages within Latino families.

Adaptation and Pilot Testing of a Sexual Health Intervention for Female Survivors of Violence

Experiences of violence and behaviors that increase the risk of acquiring a sexually transmitted infection are high among women in the United States, and they often intersect (Meyer, Springer, &; Altice, 2011 Meyer, J. P., Springer, S. A., &; Altice, F. L. (2011). Substance abuse, violence, and HIV in women: A literature review of the syndemic. Journal of Women's Health (2002), 20(7), 991–1006. doi:10.1089/jwh.2010.2328[Crossref] , [Google Scholar]; Montgomery et al., 2015 Montgomery, B., Rompalo, A., Hughes, J., Wang, J., Haley, D., Soto-Torres, L., &; Hodder, S. (2015). Violence against women in selected areas of the united states.e1-e11. Am J Public Health, 105(10), 2156–2166 [Google Scholar]; World Health Organization (WHO), 2010 World Health Organization (WHO). (2010). Addressing violence against women and HIV/AIDS: What works?. Geneva, Switzerland: World Health Organization. [Google Scholar]). However, there are few evidence-based HIV-prevention interventions that address the special needs and challenges faced by female survivors of violence (Centers for Disease Control and Prevention, (CDC), 2017a Centers for Disease Control and Prevention. (2017a). Compendium of evidence-based interventions and best practices for HIV prevention. Atlanta, GA: Division of HIV/AIDS Prevention, National Center for HIV/AIDS, Viral Hepatitis, Sexual Transmitted Diseases and Tuberculosis Prevention. Retrieved from https://www.cdc.gov/hiv/research/interventionresearch/compendium/rr/index.html [Google Scholar]). To address this gap, we adapted and pilot-tested an existing evidence-based women-focused sexual risk-reduction intervention (The Future Is Ours) with 23 self-identified female survivors of violence. The intervention comprised eight-weekly, two-hour cognitive behavioral group sessions focusing on reducing sexual-risk and improving trauma-based coping skills. Using mixed-methods analyses, the adapted intervention was determined feasible and acceptable to participants, and preliminary results suggest that participation could reduce risk factors for sexually transmitted infections. Therefore, testing on a larger scale is warranted.

以功效为切入点开展中药学教学的体会

中药学知识零碎、涉及面广、不易学习和掌握。而中药功效在中药理论中居于关键地位,它是联系药性与主治的桥梁与纽带。很多中药的四气五味、升降浮沉、临床应用等,几乎都可以从功效中体现出来。因此,教师可以通过重点分析和教授中药功效,并以此作为切入点,进行中药学学科的教学,以达到更快速、系统、牢固的学习记忆。
