Family factors and parenting in Ukraine     

《Child abuse & neglect》2017

The present study aimed to estimate the use of positive and negative parenting practices in Ukraine and explore relationships between parenting practices, intimate partner violence (IPV), alcohol use, and sociodemographics. Parents of children (N = 320) ages 9–16 from three Ukrainian regions answered questions from the Alabama Parenting Questionnaire (APQ), the Revised Conflict Tactics Scales (CTS-R), Family Adaptability and Cohesion Evaluation Scale (FACES), and the Alcohol Use Section of the Drinking and Drug History and Current Use Patterns questionnaire. Ukrainian parents who reported lower use of alcohol, balanced family functioning and lower intimate partner violence were more likely to use positive parenting and less likely to use negative parenting practices. Parents with lower education were more likely to use negative parenting practices. Furthermore, alcohol use, IPV, parent education and higher family income were significantly and indirectly related with positive and negative parenting scores. The model explained 61% of variance in the positive parenting, 67% in the negative parenting.  相似文献   

基于SEM的民俗体育进高校影响因素评价研究     

李海燕  张红兵 《湖北体育科技》2016,(5):440-446

通过构建影响因素量表,提供可供参考的影响因素体系,指导民俗体育的实践,推进民俗体育的现代化发展,形成探索民俗体育发展的共识、方法。建立SEM模型,并经过多次修正,判断影响因素的合理性、科学性,得出:民俗体育的"活动形式"是影响其现代化发展的首要因素;引导"管理者认知",推进"项目价值探索",赢取"学校支持";"源自于民间-发展于高校-回馈于社会"——课内外一体化的教学模式实现民俗体育"软着陆";回归身体价值本质探索民俗体育发展之路。  相似文献

The effects of college students’ positive thinking,learning motivation and self-regulation through a self-reflection intervention in Taiwan     

Hsin-Hui Wang  Hsiang-Ting Chen  Huann-Shyang Lin 《高等教育研究与发展》2017,36(1):201-216

This quasi-experimental study examined the effects of a self-reflection intervention on college (college in this article refers to university-level education) students’ positive thinking, learning motivation and self-regulation in Taiwan. One hundred and two college students were selected to participate in an 18-week intervention forming the experimental group (EG) which emphasized providing main lecture, role-play, self-reflection activity, group discussion and group work. Another 179 college students from two other courses were selected as a comparison group. This study showed that supportive, resourced discussion with peers and instructor, self-reflection activities and assignment as a facilitative agent improved the EG students’ positive thinking, learning motivation and self-regulation. In addition, three structural equation models revealed that positive thinking had a strong and direct relation to Taiwanese college students’ pretest learning motivation (β?=?.85) and self-regulation (β?=?.77); learning motivation had a strong and direct relation to students’ pretest positive thinking (β?=?.86) and self-regulation (β?=?.81); and self-regulation had a strong and direct relation to students’ pretest positive thinking (β?=?.83) and learning motivation (β?=?.86). Instructional implications and research recommendations are discussed.  相似文献   

Android平台下恶意软件分析与检测     

贾慧  李永忠 《教育技术导刊》2019,18(7):182-185

针对Android平台下恶意软件侵扰问题,提出一种基于权限—敏感API特征的加权朴素贝叶斯分类算法的检测方案。首先对Android应用程序中的配置文件进行解析,然后利用Apktool工具对APK文件进行反编译,提取出权限—敏感API特征集,并通过信息增益算法和卡方检验算法过滤冗余数据,最后利用加权朴素贝叶斯分类算法的恶意软件检测模型进行分类判断。实验结果证明,该系统能有效提高分类器的效率和恶意软件的检测率。  相似文献

医药冷链物流在物联网环境下的动态风险评估     

陈伟炯  王茂馨 《科技管理研究》2020,40(1):215-220

首先运用流程图法分析造成物联网环境下医药冷链物流各环节风险的众多因素源,并运用熵权法对风险指标客观赋权建立风险因素评估指标体系,然后利用Ge NIe软件建立动态贝叶斯网络模型对风险环节的关键风险因素进行概率评估。结果显示在风险评估中运输环节风险的发生概率最高,同时企业关于设备的验证选型是影响物联网医药冷链的关键风险因素,这为企业和政府控制药品质量安全管理提供了依据。  相似文献
