ABSTRACT

The recruitment of athletes with limited resources is a global problem in professional sports. In US Major League Baseball, the experience of the Oakland Athletics’ general manager in the last decade turned his “Moneyball” model into a synonym of quantitative analysis in the transfer market of baseball players. His strategy focused on hiring players with outstanding technical skills but relatively low market value. This study adapted this model to the framework of a multiple criteria decision aid (MCDA), by selecting undervalued players who have complementary abilities. The novelty here refers to the joint use of four algorithms explored by the composition of probabilistic preferences (CPP) (i.e., ranking, classification, dynamic evaluation and regularity analysis) and their application to soccer player performance evaluation. The new model analysed the recent transfer of a left-back soccer player to Europe. The results indicated 12 opportunities for better investment, among 32 left and right-back players considered. Two years later, the value of the same player was considerably lower. He played only five matches in the 2018–2019 season, without scoring or providing any assists. On the other hand, the players better classified by the CPP-MB model presented higher performances and market values.  相似文献

Objective

This study involves a reanalysis of data from a randomized controlled trial to examine whether child-parent psychotherapy (CPP), an empirically based treatment focusing on the parent-child relationship as the vehicle for child improvement, is efficacious for children who experienced multiple traumatic and stressful life events (TSEs).

Methods

Participants comprised 75 preschool-aged children and their mothers referred to treatment following the child's exposure to domestic violence. Dyads were randomly assigned to CPP or to a comparison group that received monthly case management plus referrals to community services and were assessed at intake, posttest, and 6-month follow-up. Treatment effectiveness was examined by level of child TSE risk exposure (<4 risks versus 4+ TSEs).

Results

For children in the 4+ risk group, those who received CPP showed significantly greater improvements in PTSD and depression symptoms, PTSD diagnosis, number of co-occurring diagnoses, and behavior problems compared to those in the comparison group. CPP children with <4 risks showed greater improvements in symptoms of PTSD than those in the comparison group. Mothers of children with 4+ TSEs in the CPP group showed greater reductions in symptoms of PTSD and depression than those randomized to the comparison condition. Analyses of 6-month follow-up data suggest improvements were maintained for the high risk group.

Conclusions

The data provide evidence that CPP is effective in improving outcomes for children who experienced four or more TSEs and had positive effects for their mothers as well.

Practice implications

Numerous studies show that exposure to childhood trauma and adversity has negative consequences for later physical and mental health, but few interventions have been specifically evaluated to determine their effectiveness for children who experienced multiple TSEs. The findings suggest that including the parent as an integral participant in the child's treatment may be particularly effective in the treatment of young children exposed to multiple risks.  相似文献

SCI检索下环境评价研究的文献计量学评估(1996—2005)   总被引:1,自引:0,他引:1  
通过对由SCI检索出的1996-2005年间所发表的1320篇以环境评价(EA>为主题词的论文文献进行计量学统计分析,探求EA研究现状和发展趋势.分析表明,近年来,EA研究保持着稳定的发展态势和对科学工作者持久的吸引力.环境科学、环境与工程是包括EA相关论文的主要分类目录,论文在不同期刊内呈分散分布,Environmental Management、Ecological Economics、Environmental Monitoring和Assessment等是主要的研究成果发表期刊.国际间合作成为主要的发展趋势,合作发表的论文在数量和影响力两方面都呈增长态势.另外,研究存在着区域间的不平衡,发达国家处于优势地位.不过,研究也显示了环境评价研究在获取学术资源方面有不容乐观的一面.  相似文献

高校学习型基层党组织既有一般基层党组织的共性,又有自身的特殊性。高校学习型基层党组织作为高校重要的组织机构,为高校挖掘人才和为社会发展培养精英发挥着重要的作用。但是,高校学习型基层党组织建设仍然存在着许多不足之处。为了更好地实现高校学习型基层党组织的作用,高校应完善和落实各项制度,提高党员干部的能力,提升党员的党性修养。  相似文献
