对我国西北地区沙尘暴问题的分析及预测研究

沙尘暴是一种常见的灾害性天气现象,有着爆发频繁、影响广、危害严重等特征。如今对沙尘暴的分析及趋势预测研究已成为了国内外专家学者关注的热点和焦点。本文针对我国西北地区的沙尘暴问题,利用1961～2005年中国145个区站点观测的沙尘暴天数资料,首先,对西北各主要地区沙尘暴进行了整体分析;然后,确定出了各地区和区站沙尘暴严重性的大小;最后,对各地区各区站沙尘暴情况的大致趋势进行了灰色预测分析,为政府关于沙尘暴进行防范、管理与治理提供了指导性信息。     

浅析乒乓球运动在“腱鞘炎”防治中的应用

通过对＂腱鞘炎＂发病机理的分析,得知导致＂腱鞘炎＂发生的主要原因是手部长时间重复固定动作、腕关节用力不当导致供血不足和肌腱与腱鞘过度磨损所致;经过对乒乓球运动的运动特点分析,认为乒乓球运动是一项有利于＂腱鞘炎＂预防的有效手段,建议＂腱鞘炎＂的易患人群应当经常通过乒乓球这一锻炼手段进行＂腱鞘炎＂的预防。

我国企业海外并购风险的动态监测预警与防范研究

近期中国企业的海外并购案,由于遭受东道国的各种阻碍,有些企业海外并购过程一波三折甚至无法完成并购,有些企业对并购风险估计偏差也导致海外并购最终失败。因此,企业实施海外并购时,必须全面识别和评估评估并购前、并购中和并购后的各种风险,并能够向并购方提出预警,从而及时预防、化解、控制海外并购风险。

Community-level moderators of a school-based childhood sexual assault prevention program

Childhood sexual abuse (CSA) is highly prevalent and associated with a wide variety of negative mental and physical health outcomes. School-based CSA education and prevention programs have shown promise, but it is unclear to what extent community-level characteristics are related to their effectiveness. The present cluster randomized controlled trial evaluated community-level moderators of the Safe@Lastprogramcomparedtoawaitlistcontrolcondition.(*) Knowledge gains from pre- to post-intervention were assessed in 5 domains: safe versus unsafe people; safe choices; problem-solving; clear disclosure; and assertiveness. Participants were 1177 students (46% White, 26% African American, 15% Hispanic, 4% Asian American, 6% Other) in grades 1 through 6 from 14 public schools in Tennessee. Multilevel models accounting for the nesting of children within schools revealed large effect sizes for the intervention versus control across all knowledge domains (d’s ranged from 1.56 to 2.13). The effectiveness of the program was moderated by mean per capita income and rates of substantiated cases of child abuse and neglect in the community. Intervention effects were stronger for youth living in lower as compared to higher income counties, and for youth attending schools in counties with lower as compared to higher abuse/neglect rates. Child characteristics (sex, race) did not moderate intervention effects. This research identified two community-level factors that predicted the effectiveness of a CSA education and prevention program designed to improve children’s knowledge of personal safety skills. School-based CSA prevention programs may require modification for communities with higher rates of child abuse and neglect.     

Assessing child maltreatment prevention via administrative data systems: A case example of reproducibility

Critical issues about scientific reproducibility have been raised about biomedical research, including the reliability of data and analyses within a given study. The case example in this article examined a reproducibility issue pertaining to the use of administrative data systems for evaluation of child maltreatment (CM) prevention, making use of a prevention study conducted over a decade ago that provided a unique opportunity. The place-randomization study, which randomized counties to condition, found that community-wide implementation of a parenting and family support intervention produced positive impact on county-wide rates for substantiated CM cases and out-of-home placements, documented through a state information system. The key consideration is whether and to what extent the administrative record data re-examined retroactively a decade later for the original study’s time period would yield comparable results to those based on data acquired at the time of the study. The results indicated that despite small changes over time, the same data patterns and statistical effects were reproducible for the two archival outcome variables. For substantiated CM, the reproduced analyses reflected higher effect sizes and a clear pattern of reduction as a function of intervention. For out-of-home placements, effect sizes were quite comparable to the original ones, reflecting preventive impact. Overall, this case study illustrated the verifiability of data reproducibility in the context of a population outcome evaluation, which underscores the importance of reliable population-prevalence measurement as an essential part of a comprehensive public health strategy aimed at the prevention of CM.
