岸边集装箱装卸桥是港口集装箱装卸作业中的关键生产设备 ,由于其迎风面积大 ,故而对风特别是突发的强风十分敏感。顶轨器是岸边集装箱装卸桥上重要的防风装置。在对集装箱装卸桥不增加投资的情况下 ,对原来顶轨器控制程序中的不足之处进行调整和改造 ,以满足岸边集装箱装卸桥防风的要求 ,增强集装箱装卸桥的防强风能力方面进行了一些有益的探索与实践  相似文献   

Correlates of verbally aggressive communication in adolescents     

Charles Atkin  Sandi Smith  Anthony Roberto  Thomas Fediuk  Thomas Wagner 《Journal of Applied Communication Research》2002,30(3):251-268

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  

王煜  凌蜀琪 《成都体育学院学报》1993,(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

Communicating Prevention: The Effects of the keepin' it REAL Classroom Videotapes and Televised PSAs on Middle-School Students' Substance Use     

Jennifer R. Warren  Michael L. Hecht  David A. Wagstaff  Elvira Elek  Khadidiatou Ndiaye  Patricia Dustman  Flavio F. Marsiglia 《Journal of Applied Communication Research》2006,34(2):209-227

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

Community differences in the implementation of Strong Communities for Children     

《Child abuse & neglect》2015

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
