Paternal support for child sexual abuse victims: A qualitative study

BackgroundThe current state of knowledge regarding the role of non-offending fathers in supporting their sexually abused children is very scarce.ObjectiveThe objective of this study is to further our understanding of fathers’ roles following disclosure of their children’s sexual abuse (SA) by evaluating fathers’ perceptions of the impact of disclosure on their involvement and support of their children.Participants and methodThis qualitative study relies on individual semi-structured interviews conducted with 17 fathers of allegedly abused children.ResultsInductive thematic analysis first highlighted that some reported a period of disengagement from the child during which they put into question their role and attitudes, followed by a period of re-involvement. This period of difficulties experienced by some fathers in regard to their involvement towards their children was due to either their own important psychological distress, their ambivalence towards their child or even because of feelings of uneasiness experienced during physical contact with them. Despite this, findings indicate the presence of thoughts and attitudes that suggest children are a source of concern for fathers. The four forms of abuse-specific support previously observed among mothers (believing the child, seeking out professional services, protecting him/her from the offender, supporting him/her emotionally) were also observed among fathers. In accordance with the activation theory, a form of support specific to fathers, namely, encouraging the child to open up to and explore the world outside the family, thereby, fostering the child’s self-esteem development, was observed and constitutes a relevant finding.ConclusionClinical and empirical implications are discussed.     

反兴奋剂工作中的临时停赛规则评述

临时停赛是反兴奋剂工作中较为常见的管理手段，依托反兴奋剂规则体系的建设，临时停赛规则整体上体现出了一致性和灵活性兼备的特点。但由于《世界反兴奋剂条例》临时停赛条款关键内容的缺失，以及各反兴奋剂组织的反兴奋剂规则补充规定的不完善，临时停赛规则的一致性和灵活性相结合的优势未能获得充分发挥，不利于运动员权利的保护，也影响了国际反兴奋剂工作公平协调地进行。完善临时停赛规则应当强调《世界反兴奋剂条例》与各体育组织、反兴奋剂机构的反兴奋剂规则之间的“分工”，并重点关注临时停赛的适用标准、停止条件、违规后果、时长标准和赔偿规则等问题。我国的临时停赛规则存在实践适用较少、认定标准简单的问题，应当借鉴国际经验进一步完善相关规定，助力我国反兴奋剂事业的发展。     

Understanding the relative contribution of technical and tactical performance to match outcome in Australian Football

ABSTRACT

The aim of this study was to assess if tactical and technical performance indicators (PIs) could be used in combination to model match outcomes in Australian Football (AF). A database of 101 technical PIs and 14 tactical PIs from every match in the 2009–2016 Australian Football League (AFL) seasons was merged. Two outcome measures Win-loss and Score margin were used as dependent variables. The top 45 ranked technical and tactical PIs from a feature selection process were used to model match outcome using decision tree and Generalised Linear Models (GLMs). Of the top 45 selected features, this included seven tactical PIs. The Win-loss-based Decision tree model achieved a classification accuracy of 89.0% and GLM 93.2%. A Score margin-based GLM achieved a root mean squared error (RMSE) of 6.9 points. A combined approach to the classification of match outcomes provided no improvement in model accuracy compared with previous literature. However, this study has established the relative importance of technical and tactical measures of performance in relation to successful team performance in AF.
