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

基于系统动态学方法的弱信号生命周期建模与仿真     

董尹  刘千里  宋继伟 《图书情报工作》2019,63(13):75-84

[目的/意义]为增强弱信号的内涵研究，对其全生命周期过程下的各阶段要素以及要素间的联系进行探寻，以期获得一定程度上的理论贡献，同时也为相关组织在开展弱信号管理实践时提供理论指导。[方法/过程]在对弱信号概念研究现状进行梳理的基础上，结合意义构建理论给出了弱信号概念界定。随后，通过与信息生命周期、新兴议题生命周期进行类比，提出弱信号生命周期理念。进而采用系统动态学方法开展系统思考，使用因果回路图进行系统建模，运用存量流量图进行仿真模拟。[结果/结论]弱信号生命周期包含4个阶段：侦测、关联、传递、抉择，相应的系统动态学模型所具备的现实性得到验证，且通过情景模拟确认了4个关键辅助变量：外界噪声干扰程度、弱信号分析效率、组织内相互信任程度、决策者信任程度。在整体研究的基础上，给出弱信号管理过程中可能会遇到的障碍以及应对策略。  相似文献

Technology's impact: symbiotic or asymbiotic impact on differing cultures?     

Cheng‐Chang Pan  Ming‐Hsiu Tsai  Ping‐Ye Tsai  Yedong Tao  Richard Cornell 《Educational Media International》2013,50(3-4):319-330

Over the past three years or more, the authors have been examining the impact of technology interventions on students and teachers – from cultures where English is a second language. It is their hypothesis that students and teachers from non‐English speaking nations suffer severe disadvantages when technological interventions are superimposed on existing traditional pedagogical models. This paper is the latest in a series that examines extent pedagogies, primarily in Asia, and the pressures of having to re‐conceptualize what has been a tradition for centuries. It traces significant educational origins to their cultural roots and examines contemporary initiatives that, if implemented, may well disrupt. It offers possible solutions that, if approached with reconciliation as its focus, might offset catastrophic results and, in fact, achieve pedagogical symbiosis.L'impact de la technologie: symbiotique ou asymbiotique selon des cultures différentes. Durant les 3 dernières années ou plus, des auteurs ont examiné les interventions sur les étudiants et les enseignants appartenant à des cultures où l'anglais est une seconde langue. C'est une hypothèse que les étudiants et enseignants de pays non anglophones souffrent de plusieurs d´esavantages quand les interventions technologiques sont imposées sur les modèles pédagogiques traditionnels. Cet article est le plus récent d'une série qui examine plusieurs pédagogies, particulièrement en Asie, et les pressions de revoir la conceptualisation qui a été la tradition pendant des siècles. Il met les origines éducatives significatives depuis leurs racines culturelles et examine les initiatives contemporaires qui, si elles sont en oeuvre, peuvent aboutir à des ruptures. L'article offre des solutions possibles qui, si elles sont approchées dans un esprit de conciliation comme point de mire, permettent d'éviter des résultats catastrophiques et, en fait, aboutir à une symbiose pédagogique.Die Wirkung der Technik: Symbiotische oder Asymbiotic Wirkung auf unterschiedliche Kulturen? Über die letzten drei Jahre oder mehr haben die Autoren die Wirkung von Technikeingriffen auf Studenten und Lehrer aus Kulturen geprüft, in denen Englisch eine zweite Sprache ist. Es ist ihre Hypothese, daß Studenten und Lehrer aus nicht englisch sprechenden Nationen schwerwiegende Nachteile erleiden, wenn mit technologischen Eingriffen vorhandene traditionelle pädagogische Modelle überlagert werden. Dieses Papier ist das letzte einer Serie, die umfangreiche pädagogische Gebiete untersucht, in erster Linie in Asien, und den Zwang prüft, das wieder konzeptualisieren zu müssen, was Jahrhunderte eine Tradition gewesen ist. Es verfolgt signifikante Bildungsursprünge hin zu ihren kulturellen Wurzeln und prüft zeitgenössische Initiativen, die, wenn durchgeführt, das gut unterbrechen können. Es bietet mögliche Lösungen an, die, mit dem Ziel der Aussöhnung, katastrophale Ergebnisse ausgleichen und in der Tat eine pädagogische Symbiose erreichen könnten.  相似文献

Architecture Singularity Analysis of 4-U■S/U■U 5-DOF Parallel Mechanism     

齐明  郄彦辉 《天津大学学报(英文版)》2007,(6)

Architecture singularity of a parallel mechanism with five degrees of freedom (DOF) is analyzed. Such mechanism consists of a movable platform connected to the base by five active limbs. Four of them are identical 6-DOF limbs and the last one has the same DOF as the specified DOF of the movable platform. Based on the kinematics analysis, two categories of architecture singularities for such mechanism are proposed. Then the sufficient condition for each singularity is researched. Results show that the mechanism is singular when it employs each category of the proposed architecture, provided that it satisfies the corresponding sufficient condition. It can be concluded that the proposed two categories of architecture singularities should be avoided with the following dimensional synthesis of such mechanism.  相似文献   

关怀理论:教师专业成长中不可忽视的内容     

蒋茵 《台州学院学报》2006,28(4):66-69,73

诺丁斯的关怀理论是20世纪80年代中期提出,并随着90年代初兴起的“学会关心”这一国际教育思潮而备受关注。它为教师的专业成长提出了一种新的研究视角:彰显教师的非理性精神来挑战传统理性;以学习关怀为出发点而建构学校教育和教师成长的新内容;在关怀实践中提升教师专业成长的责任感与动力。  相似文献
