Family poly-victimization and cyberbullying among adolescents in a Chinese school sample

The sustained increase in their use of social networking facilitates the development of adolescents but comes with the risk of cyberbullying, which creates new challenges in regard to adolescent protection. Past evidence shows that family victimization may play an essential role in the way adolescents learn cyberbullying behaviors. Yet, research on the co-occurrence of family victimization and cyberbullying is limited. This study aims to investigate the associations between cyberbullying and family victimization among adolescents, and to examine the health correlates of cyberbullying and family poly-victimization. A large sample of 18,341 students, aged 15–17, from six cities in China, collected between 2009 and 2010 is employed in the present study, which investigated the association between various kinds of family victimization and adolescent cyberbullying. Data analysis was conducted in 2017. In-law conflict, intimate partner violence, elder abuse and neglect, and child maltreatment were associated with a higher possibility of children becoming internet victims. Parents’ divorce and separation, low family income, mother’s low level of education, and father’s unemployment were all associated with cyberbullying victimization. Cyber victimization was positively correlated to symptoms of PTSD and depression, self-harm, and other physical and mental health variables. Possible explanations for the relationships found in this study are discussed and implications for future research and services are provided. Proactive screening for family poly-victimization and cyberbullying is suggested. Schools are highly recommended to cooperate with parents to promote cyber safety.     

Verbal abuse during pregnancy increases frequency of newborn hearing screening referral: The Japan Environment and Children’s Study

BackgroundVerbal abuse during pregnancy has a greater impact than physical and sexual violence on the incidence of postnatal depression and maternal abuse behavior towards their children. In addition, exposure of children (aged 12 months to adolescence) to verbal abuse from their parents exerts an adverse impact to the children’s auditory function. However, the effect of verbal abuse during pregnancy on fetal auditory function has not yet been thoroughly investigated.ObjectiveThe objective of the study was to examine the relationship between intimate partner verbal abuse during pregnancy and newborn hearing screening (NHS) referral, which indicates immature or impaired auditory function.Participants and settingThe Japan Environment and Children’s Study is an ongoing nationwide population-based birth-cohort study designed to determine environmental factors during and after pregnancy that affect the development, health, or wellbeing of children. Pregnant women living in 15 areas of Japan were recruited between January 2011 and March 2014.MethodsMultiple imputation for missing data was performed, followed by multiple logistic regression using 16 confounding variables.ResultsOf 104,102 records in the dataset, 79,985 mother–infant pairs submitted complete data for questions related to verbal and physical abuse and the results of NHS. Of 79,985 pregnant women, 10,786 (13.5%) experienced verbal abuse and 978 (1.2%) experienced physical abuse. Of 79,985 newborns, 787 (0.98%) received a NHS referral. Verbal abuse was significantly associated with NHS referral (adjusted odds ratio: 1.44; 95% confidence interval: 1.05–1.98).ConclusionsVerbal abuse should be avoided during pregnancy to preserve the newborn’s auditory function.     

基于主成分投影法的东北老工业基地产业集群伙伴选择研究

东北老工业基地是以国有大型企业为核心,众多中小企业和相关机构组成的地理集聚体。这种特点决定了其产业集群是以核心企业为主体,通过集群合作伙伴的选择来组建产业集群。集群伙伴合作能力的评价是组建集群的关键。由于集群合作伙伴选择的评价是多目标、多属性评价,而且评价指标间的信息相互重叠,因此提出了基于主成分投影法的集群伙伴合作能力评价选择,分析了集群合作伙伴选择原则,构建了评价指标体系,建立了基于主成分投影法的集群伙伴合作能力评价模型,并结合算例加以应用。

中国企业战略联盟伙伴特征匹配标准实证研究

导致联盟失败最关键的因素之一就是联盟伙伴的不匹配。该文章基于文献研究,对战略联盟伙伴选择的特征匹配标准进行要素分析,重点分析了资源互补度、战略目标相容度、文化协同度与联盟前联系度对联盟绩效的影响,并构建联盟伙伴特征匹配状况评价模型;通过实际调研获得的中国企业构建战略联盟的大样本数据,对联盟伙伴特征匹配状况评价模型进行检验。结果显示,资源互补度、文化协同度和联盟前联系度是中国企业构建联盟中最重要的三个伙伴选择指标,而战略目标相容度在中国企业的联盟实践中并不被重视。     

企业原始创新中学研合作伙伴的选择——基于影响因素及其作用路径视角的分析

将创新类型因素及伙伴合作意愿因素考虑到企业伙伴选择影响因素路径分析中,在问卷调查的基础上,运用结构方程模型及多群组结构方程模型等方法,对企业原始创新中学研合作伙伴选择的影响因素及其作用路径进行了实证分析。结果表明:企业原始创新能力虽不直接影响企业伙伴选择过程,但通过学研方参与原始创新的意愿间接影响企业伙伴选择投入及企业伙伴评价过程,企业伙伴选择投入及企业伙伴评价过程是企业与学研方建立正式合作关系的重要影响因素。企业规模特征、企业行业特征及企业所有权性质在不同假设路径中的影响均存在显著差异。研究结论为企业及政府制定相关政策措施促进我国产学研合作原始创新提供了依据。     

基于SAO分析的R&D合作伙伴识别研究

随着技术创新知识复杂性的不断增加和产品生命周期的不断缩短,企业需要拓宽知识基础来应对环境的快速变化,需要从外部寻求合作机会来改善企业内部创新过程或提升现有研发能力,因此,如何识别和选择合适的合作伙伴便成为企业的重点关注。本文提出了基于SAO分析的RD合作伙伴识别方法,该方法通过提取文献标题及摘要中的SAO结构,绘制涵盖材料、技术与组件,以及目标等三个维度的SAO结构图,通过挖掘具有相似研发目标的机构,分析其互相合作的可能性及可能的合作方向,并以染敏太阳能电池技术(DSSCs)为案例开展研究,证实了该方法的可行性和有效性。
