Interpersonal violence against children in sport in the Netherlands and Belgium     

《Child abuse & neglect》2016

The current article reports on the first large-scale prevalence study on interpersonal violence against children in sport in the Netherlands and Belgium. Using a dedicated online questionnaire, over 4,000 adults prescreened on having participated in organized sport before the age of 18 were surveyed with respect to their experiences with childhood psychological, physical, and sexual violence while playing sports. Being the first of its kind in the Netherlands and Belgium, our study has a sufficiently large sample taken from the general population, with a balanced gender ratio and wide variety in socio-demographic characteristics. The survey showed that 38% of all respondents reported experiences with psychological violence, 11% with physical violence, and 14% with sexual violence. Ethnic minority, lesbian/gay/bisexual (LGB) and disabled athletes, and those competing at the international level report significantly more experiences of interpersonal violence in sport. The results are consistent with rates obtained outside sport, underscoring the need for more research on interventions and systematic follow-ups, to minimize these negative experiences in youth sport.  相似文献   

Author bibliographic coupling analysis: A test based on a Chinese academic database     

Ruimin Ma 《Journal of Informetrics》2012,6(4):532-542

The paper first introduces the basic problems of author bibliographic coupling including the relationship between author bibliographic coupling and document bibliographic coupling as well as the three calculation methods of author coupling strength, namely, simple method, minimum method and combined method. Next I choose a small sample of authors in Chinese library and information science (LIS) as the research objects to have a comparative analysis of three types of author coupling strength algorithms (the data source is from the Chinese Social Sciences Citation Index (CSSCI)). The result shows that the minimum method is the most appropriate one to calculate the author coupling strength. Then a large sample of authors is chosen to analyze the intellectual structure of Chinese LIS. The result shows that author bibliographic coupling analysis (ABCA) can discover the intellectual structure of a discipline better. It is also found that compared with author cocitation analysis (ACA), ABCA has the advantage that it not only can discover the intellectual structure of a discipline more comprehensively and concretely but also can reflect the research frontier of the discipline. Finally, some practical problems that arise during this research are discussed.  相似文献

发表时滞与论文影响力关系研究——以图书情报学中文核心期刊为例     

韩牧哲  李秀霞  王冬  刘超 《中国科技期刊研究》2016,27(7):785-792

【目的】探析发表时滞与论文影响力的关系,寻找使论文影响力最大化的理想时滞区间,构建了发表时滞与论文影响力关系数学模型。【方法】采集2013年图书情报学中文核心期刊论文的发表时滞和被引频次数据,利用双参数威布尔分布的概率密度函数,分别对采集到的3785篇论文的发表时滞的概率分布、发表时滞与论文影响力的关系曲线进行拟合。【结果】2013年能使论文影响力最大化的理想发表时滞区间为31至210天,当年论文发表时滞的实际分布区间与理想状态尚存差距。【结论】进一步分析认为论文的影响力与其发表时滞的长短存在相关关系,存在能使论文影响力最大化的理想时滞区间,但发表时滞并非越短越好,预测国内期刊论文发表时滞有进一步缩短的趋势。  相似文献   

Information security risk analysis model using fuzzy decision theory     

《International Journal of Information Management》2016,36(1):25-34

This paper proposes a risk analysis model for information security assessment, which identifies and evaluates the sequence of events – referred to as alternatives – in a potential accident scenario following the occurrence of an initiating event corresponding to abuses of Information Technology systems. In order to perform this evaluation, this work suggests the use of Event Tree Analysis combined with fuzzy decision theory. The contributions of the present proposal are: the development of a taxonomy of events and scenarios, the ranking of alternatives based on the criticality of the risk, considering financial losses, and finally, the provision of information regarding the causes of information system attacks of highest managerial relevance for organizations. We included an illustrative example regarding a data center aiming to illustrate the applicability of the proposed model. To assess its robustness, we analyzed twelve alternatives considering two different methods of setting probabilities of the occurrence of events. Results showed that deliberate external database services attack represent the most risky alternative.  相似文献
