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

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

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

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

There is evidence that pupils with weak literacy skills struggle on transition to secondary school. Many experience a drop in attainment in the summer break between the two. A British government‐funded programme of rigorously designed research on boosting literacy at transition had (by 2015) found only four of 15 interventions evaluated had positive effects. This small‐scale quasi‐experimental study investigated the effectiveness of support for pupils with mild literacy difficulties on transition to secondary school. Thirty‐two pupils in three schools were involved; half received the programme. Pairs were matched on reading, spelling, age and gender. Intervention was designed around the individual needs of each pupil, focusing variously on language skills, writing, reading and spelling. The group receiving the programme made modest gains in spelling, reading efficiency and single word reading. The comparison group lost ground, relatively, in all three areas. The results suggest a promising line for more rigorous investigation. 相似文献

Television viewers construct many different meanings from the programs they watch. Here, we investigated whether ethnic prejudice is differentially influenced by the genre of television programs in their portrayal of ethnic minorities. We also wanted to determine whether a higher educational level reduces ethnic prejudice and television use. A self-reported questionnaire was administered to 401 Italian adults. Structural equation modeling was used to analyze the relationships between ethnic prejudice and television program contents and educational level. Viewing Reality and Variety Shows was positively related to ethnic prejudice, News and Public Affairs was negatively related, and Films and TV series had no apparent influence on prejudice. Educational level was negatively related to both ethnic prejudice and watching Reality and Variety Shows, and positively related to viewing News and Public Affairs and Films and TV series programs. 相似文献

摘要:男子三级跳远是我国参加奥运会田径比赛的潜优势项目,专项力量是影响三级跳远比赛成绩和技术水平提升的关键因素,运用文献资料法、专家访谈法、实地调查等研究方法,分析研究我国最优秀的6名男子三级跳远运动员专项力量训练安排。结论:1)我国男子高水平三级跳远运动员的力量训练内容、方法手段、计划与负荷基本符合世界潮流,但训练中缺少单腿支撑进行的蹲、拉、提、举等练习,不够贴近专项需要;2)专项力量训练器材与世界发达国家相比科技化含量不高;3)专项力量负荷调整控制主要依赖教练员经验与身体素质指标推算。 相似文献

中国城乡消费水平差异对资源环境影响的比较 总被引:1,自引:0,他引:1
中国城乡发展差异显著,消费水平不一,造成人口消费占用的资源环境空间差距较大。本文探究城乡不同消费群体的资源环境影响效果,有助于更好地认识资源环境问题,促进城乡科学协调发展。基于人均消费性支出和单位人概念,研究了1957年-2005年中国城乡消费对资源环境影响的时序变化及相对状况。结果表明,当前1个单位人对环境产生的压力相当于1950年代6~7个单位人的压力;1个城镇居民消费占用的资源环境空间约相当于3个农村居民消费占用的空间;城镇居民对资源环境影响强度超过农村居民约20年;城镇居民对资源环境影响总量增加了34.2倍,农村居民增加了8.33倍;1957年城镇居民对资源环境影响量占36.09%、农村居民占63.91%,2005年城镇居民占68.05%、农村居民为31.95%;1997年之前农村人口消费对资源环境影响量占较大份额,1997年以来城镇人口消费成为资源环境影响的主要方面。 相似文献
