This investigation identifies demographic, media, and social correlates of verbally aggressive communication in adolescence. Mail surveys were completed and returned by 2,300 adolescents between the ages of 13 and 15. These adolescents were asked about the prevalence of verbal and physical aggression, the context in which it occurred, demographics, and the interpersonal and media influences in their lives. The results indicate that verbal aggression is widespread, that committing and experiencing verbal aggression is largely reciprocal, that there is a strong relationship between committing verbal and physical aggression, and that peer social influence and listening to violently oriented music are mildly related to verbal aggression in adolescents. These findings suggest more resources should be allocated to teaching adolescents to understand and control verbal aggression. Further, they provide important answers to many prevention and intervention programmatic questions, including context, content, and targeting concerns. Since the negative consequences of verbal aggression are severe and long lasting, decreasing this destructive communication behavior should significantly improve the lives of many adolescents. These and other practical implications are expanded upon and discussed. 相似文献

我国优秀击剑运动员运动损伤的特点及预防原则 总被引:1,自引:0,他引:1
为了探索我国击剑运动员损伤的发病规律,在第十一届亚运会中国击剑队集训期间,笔者采用病史询问和详细的局部检查,调查了中国击剑集训队和部分省市击剑队193名队员的运动损伤情况,结果显示:带伤者172人,占89.12%,共289例次,涉及到38种损伤,其中慢性损伤占90%以上,训练年限越长,损伤的发生率越高,发病部位集中于持剑手侧的膝关节伸膝装置(25%)持剑手侧肩部(9.7%),腰部肌(13%)和踝关节(9.3%)等。从剑种上看,花剑选手以持剑手侧膝关节髌腱腱病和髌尖末端病、持剑手侧腕关节软组织劳损多见,而重佩剑队员则以持剑手肩关节软组织损伤多见。损伤的基本原因与击剑专项技术的特殊要求有密切关系,其次与忽视准备活动和放松练习等有关,由此,提出了以加强肌肉力量训练,认真做好准备活动并重点结合运动前的防护准备,加强医务监督的预防原则。 相似文献

This study sought to determine if exposure to two communication-oriented activities, videotapes and public service announcements, accounts for changes in substance use among adolescents participating in the Drug Resistance Strategies Project's keepin' it REAL adolescent substance use prevention curriculum. Middle-school students (4,734, 72% Latino) responded to questionnaires related to these analyses. An analysis of covariance (ANCOVA) model was fit separately to six substance use outcomes. The results suggested that intervention students who saw four or five videos engaged in less substance use in the past month than did students who saw fewer videos. Having seen the PSAs one or more times did not predict the reported change in substance use. 相似文献

In 1993, the U.S. Advisory Board on Child Abuse and Neglect recommended a neighborhood-based strategy to prevent child abuse and neglect. The Board further recommended the development of Prevention Zones to allow for testing of the effectiveness of community-wide child protection efforts in neighborhoods of differing population density, ethnic and cultural composition, and social and economic resources. Following the Board's recommendation, this article presents the results of a trial of the effectiveness of a neighborhood-based strategy in low- and high-resource communities. Using management, survey, and administrative data, the research showed that both community types experienced declines in founded cases of and injuries suggesting child maltreatment for children under age 5. Low-resource communities experienced greater levels of mobilization, as measured by community and institutional engagement, and a greater number of positive outcomes related to changes in the quality of life for families and community norms relative to child and family well-being. In particular, the low-resource communities experienced the largest increases in receiving help from neighbors, neighboring, perceived household safety for neighborhood children, and observed positive parenting. High-resource communities experienced greater increases in intermediate outcomes related to self-reported parenting practices. The findings suggest that, ultimately, community mobilization can occur and be an effective means of preventing child maltreatment across community types. It appears, however, that community mobilization may play a more significant role in low-resource communities. 相似文献

Bringing evidence-based treatments to community practice is a critical challenge for the field. When implemented in the community, evidence-based treatments often fail to provide the benefits shown in laboratory settings. Therefore, when evidence-based treatments are transported to the community, it is essential to investigate implementation process and outcomes. The present study assessed whether Attachment and Biobehavioral Catch-up (ABC), an intervention for high-risk parents that has been shown to be efficacious in randomized clinical trials (RCTs), changed parent behavior in a community-based setting. This study examined data collected from 78 cases by 9 parent coaches in a diverse community setting in Hawaii, and compared data to benchmarks from RCTs. Parent coach fidelity was coded from intervention session video clips, and was also compared with benchmarks. Caregivers participating in ABC were primarily birth parents, and most were referred through Child Protective Services involvement or for reasons of harsh parenting or neglect. Parental behavior was assessed before and after intervention using a semi-structured play task. Increases in parental following the lead and delight, and decreases in parental intrusiveness, were observed; these changes were comparable to effect sizes observed in RCTs. Intent to treat analyses were conducted using behavioral data from videotaped sessions, and suggested that ABC also improved following the lead in parents who subsequently dropped out of treatment. These results support the viability of ABC for enhancing parenting behavior among parents at high risk for maltreatment, and demonstrate that parent coaches in community agencies can successfully implement ABC. 相似文献

In the last few years there has been a significant increase in the number and scope of social science research into doping in sport. However, despite this apparent progress, the field remains a disparate body of work and lacks both direction and leadership. Whilst sport management is a discipline that is well suited to provide such leadership, scholarly research into this controversial topic has not been published widely in sport management journals. This special issue redresses this gap by bringing together a range of scholarly articles that represent a variety of perspectives by authors from North America, Europe and Australia. The issues and challenges covered are varied, but each paper brings a common theme: the implications for the management of doping in sport. The six papers in this Special Issue of Sport Management Review are a significant addition to the slowly growing body of sport management scholarly work on doping in sport. It is hoped that future research will be prompted with this Special Issue and the discipline of sport management will recognize and respond to the challenges presented by doping. 相似文献

We hypothesised that resiliency may protect adolescents against risky behaviours, and that both the practicing of sports, and gender are moderating variables in relationships between resiliency and risky behaviours. The study included 18-year-old pupils from a selection of secondary schools (n = 556). A total of 188 individuals practiced competitive sports and the remaining 368 participants were non-athletes. The participants were examined with the Resiliency Assessment Scale for Children and Adolescents (SPP-18) and with a survey containing questions and statements related to high-risk “experiments with adulthood”. Adolescent athletes showed higher levels of resiliency than their peers. The power of the “Determination and Persistence in Action” effect on “Alcohol” scale differed significantly between male athletes and male non-athletes. Only in the athletes groups were higher scores on this scale reflected by lower values on the “Drugs” scale. Moreover, it is possible to observe differences in undertaking risky behaviour between male and female athletes. The analysis of risky sexual behaviour suggests that sport is a risk factor for men, and a protective factor for women. These data suggest that consistent prophylactic and psycho-educative activities, with a special attention to differences between genders, should be provided to all the adolescents, irrespective of their sport performance levels. 相似文献

现代科学技术的广泛运用在为社会带来巨大利益的同时,也不可避免地产生了大量的致险源,人们稍有不慎就可能危及他人的生命财产安全,目前过失犯罪率不断上升就是明证。过失犯罪是由主体内外因素综合互动引发的,但是行为主体社会责任感不强、经验泛化和注意品质的缺陷是导致过失犯罪的主要因素。因此,行为主体注意调适和优化上述三个方面,就能够有效地预防过失犯罪。 相似文献
