对七省市三十所高校大学生课外科技活动现状的调查研究

大学生课外科技活动是培养大学生创新能力的重要平台。通过问卷调查和访谈等方式对我国七省市三十所高校的实证研究表明,目前的大学生科技创新活动存在重科研轻科普、重获奖轻立项、重精英轻普及等功利观念;学生科研资金不足,实验设备、指导教师配备不足等现实问题;学校评价体系不健全等制度缺陷。这些问题影响制约了大学生课外科技活动的深入开展。     

Maybe We Should Just Shut Up: The Body as an Important Consideration for Group Work Practice

ABSTRACT

This article explores the role of the human body as an important consideration for group work. It discusses six concepts related to how the body can be paid attention to and utilized within the realm of practice. These concepts include the idea of the body as related to the sense of self; physical experience as metaphor; the body as a barometer of group experience; shared physical experience and group cohesion; physical experiences and behavior; and the notion of somatic intelligence and communication. Examples of each are discussed from the lens of the author's practice.     

Social Activity,School-related Activity,and Anti–substance Use: Media Messages on Adolescent Tobacco and Alcohol Use

In this article, we present the effects of three hypothesized protective factors—social activities, school-related activities, and anti–substance use media messages—on adolescent tobacco and alcohol use. Data were drawn from the “Monitoring the Future” research project, which was conducted by the Institute for Social Research at the University of Michigan. The sample included 2,551 twelfth-grade students. The results of the structural equation model showed that exposure to media anti-drug messages had an indirect negative effect on tobacco and alcohol use through school-related activity and social activity. The results suggest that comprehensive ecological interventions encompassing media, family, and school can increase the preventive effects of adolescent's substance use.     

Physical Activity as a Helpful Adjunct to Substance Abuse Treatment

ABSTRACT

While limited research exists on the topic of physical activity as an adjunct to substance abuse treatment, a review of relevant multidisciplinary literature indicates a logical rationale for its potential benefits to recovery from addiction. This article provides an overview of common variables that contribute to addictive disease and summarizes the relationship of regular physical activity to improvements on many of these variables. The stages of change from the Transtheoretical Model (TTM, Prochaska & DiClemente, 1982; Prochaska & Velicer, 1997) are described in the context of effectively matching clients in substance abuse therapy to interventions that may include physical activity. Finally, important practical suggestions for implementing physical activity as a useful adjunct to substance abuse treatment are provided.     

Supportive Group Interventions with Caregivers of Frail Older Adults

The use of supportive group interventions with caregivers of frail older adults is discussed in this article. Four categories of group interventions are described: (1) mutual support groups, (2) psychoeducational groups, (3) social, recreational and educational groups, and (4) service and advocacy groups. Research evidence on the efficacy of group interventions with this population is also considered. Recommendations are made on when to refer caregivers to support groups and on what type of support group is most appropriate. Consideration by practitioners and program planners of a broader range of types of supportive groups is also encouraged.
