一流大学建设高校海归教师科研表现自我评价的调查分析     

朱佳妮  吴菡 《高等教育研究》2018,(12):55-60

高校海归教师是归国留学人员的重要组成群体,他们知识储备丰富、国际化视野宽广。本研究基于跨文化再适应视角,采用问卷调查的方式,对41所一流大学建设高校的1417名海归教师回国后的科研表现及其主要影响因素进行调查分析。调查结果显示,海归教师对其在课题申报和成果发表方面的评价不高;其在海外学习和工作期间的适应情况、对院系工作氛围的认同程度以及与海外导师、同事或同门开展合作的频率,对海归教师的科研表现具有显著的正向影响。  相似文献   

Granularity of algorithmically constructed publication-level classifications of research publications: Identification of topics     

Peter Sjögårde  Per Ahlgren 《Journal of Informetrics》2018,12(1):133-152

The purpose of this study is to find a theoretically grounded, practically applicable and useful granularity level of an algorithmically constructed publication-level classification of research publications (ACPLC). The level addressed is the level of research topics. The methodology we propose uses synthesis papers and their reference articles to construct a baseline classification. A dataset of about 31 million publications, and their mutual citations relations, is used to obtain several ACPLCs of different granularity. Each ACPLC is compared to the baseline classification and the best performing ACPLC is identified. The results of two case studies show that the topics of the cases are closely associated with different classes of the identified ACPLC, and that these classes tend to treat only one topic. Further, the class size variation is moderate, and only a small proportion of the publications belong to very small classes. For these reasons, we conclude that the proposed methodology is suitable to determine the topic granularity level of an ACPLC and that the ACPLC identified by this methodology is useful for bibliometric analyses.  相似文献   

Research universities on the ResearchGate social networking site: An examination of institutional differences,research activity level,and social networks formed     

Weiwei Yan  Yin Zhang 《Journal of Informetrics》2018,12(1):385-400

As one of the largest active academic social networking sites, ResearchGate (RG) has been utilized by scholars to share publications, seek collaborators, communicate work in progress, and build scholarly reputation. This study collects data from RG users from 61 U.S. research universities at different research activity levels, as categorized by the Carnegie Classification of Institutions of Higher Education, to examine the impact of institutional differences on RG reputational metrics. The results confirm that RG is a research-oriented academic social networking site that closely and realistically mirrors the research activity level of institutions. With an increase in the research activity level of a university, its affiliated RG users tend to have higher RG scores, more publications and citations, and more profile views and followers, while the average number of reads of their publications and followees tend to be lower and fluctuant. In addition, RG users primarily follow others from institutions of a higher research activity level, forming virtual social networks centered around esteemed institutions. The study suggests academic social networks can serve as indicators in evaluation of research activities among research institutions, and such sites can be helpful and credible for acquiring resources, keeping informed about research, and promoting academic influence.  相似文献   

Child protection workers dealing with child abuse: The contribution of personal,social and organizational resources to secondary traumatization     

《Child abuse & neglect》2016

The present study compared secondary traumatization among child protection social workers versus social workers employed at social service departments. In addition, based on Conservation of Resources (COR) theory, the study examined the contribution of working in the field of child protection as well as the contribution of background variables, personal resources (mastery), and resources in the workers’ social and organizational environment (social support, effectiveness of supervision, and role stress) to secondary traumatization. The findings indicate that levels of mastery and years of work experience contributed negatively to secondary traumatization, whereas exposure to child maltreatment, trauma history, and role stress contributed positively to secondary traumatization. However, no significant contribution was found for social support and effectiveness of supervision. The study identifies factors that can prevent distress among professionals such as child protection workers, who are exposed to the trauma of child abuse victims. Recommendations are provided accordingly.  相似文献

LIU Jing 《海外英语》2014,(10):239-240

Infinitives which consist of bare infinitive and infinitival to are imperative in linguistic studies.And both of the two kinds of infinitives do not indicate person,tense and number.This research aims to analyze the properties,similarities and differences between bare infinitive and infinitival to from the perspective of syntax.Thus,it enables us to attain a uniform characterization of the infinitival to and bare infinitive on the syntactic level and help us to understand these two kinds of infinitives better.  相似文献

檀志宗  楼俊华  李男 《体育科研》2019,(6):93-97

采用问卷调查法对浙沪两省市194名游泳运动员进行运动性伤病调查，主要从运动性伤病的类型、部位、性质方面对比分析不同竞技水平游泳运动员的伤病表型特征。结果显示：优秀运动员运动性损伤较常见，多以慢性劳损为主，损伤部位依次为肩关节、腰背部和膝关节；一般运动员常发生急性损伤，损伤部位依次为膝关节、肩关节和腰背部。两组运动员鼻炎和中耳炎均常见。因此，依据运动性伤病的可能原因与机制，需要制定有针对性的预防措施，以减少运动性伤病的发生。  相似文献
