基于Cite Space的国内身体功能训练研究计量学分析     

蒋晓帆 《体育科技文献通报》2020,(1):155-157

运用中国知网(CNKI)检索库进行检索,共查找到期刊文献115篇,其中国内期刊65篇,硕士论文31篇。通过Cite Space和中国知网(CNKI)文献分析功能,对国内身体功能训练研究进行计量学分析。研究的基本特征表现为:研究机构多,文献期刊发表数量较少,核心期刊占比较少,论文质量与数量之间存在差异。研究热点以身体功能训练为主,并突显了“功能训练”“训练”和“体育工作者”等关键词,作者合作比较少,仅形成数个微小的作者合作网络。  相似文献   

The impact of student misconceptions on student persistence in a MOOC     

Chen Chen  Gerhard Sonnert  Philip M. Sadler  Dimitar Sasselov  Colin Fredericks 《科学教学研究杂志》2020,57(6):879-910

Massive Online Open Courses (MOOCs) provide opportunities to learn a vast range of subjects. Because MOOCs are open to anyone with computer access and rarely have prerequisite requirements, the range of student backgrounds can be far more varied than in conventional classroom-based courses. Prior studies have shown that misconceptions have a huge impact on students' learning performance; however, no study has empirically examined the relationship between misconceptions and learning persistence. This study of 12,913 MOOC-takers examines how students' misconceptions about the upcoming course material affect course completion. Using a survival analysis approach, we found that, controlling for the score in a pre-course test, students holding more misconceptions had a higher dropout rate at the start of the course, an effect that diminished over time. Other student variables were found to have a positive impact on survival that persisted throughout the entire course: U.S. location, higher age, an intention to complete, better English skills, prior familiarity with the subject, motivation to earn a certificate, and score and time spent on the previous problem set (homework). By contrast, student gender, education level, number of previous MOOCs completed, and motivation to participate in online discussion forums did not affect survival.  相似文献   

软件平台开放度对主导企业绩效影响研究——基于平台吸引力的调节作用     

孙耀吾  旷冶 《科学学与科学技术管理》2016,(5):44-54

从平台开放资源视角,探讨平台开放度对主导企业绩效的影响机理以及不同维度的平台吸引力对以上过程的调节作用。对中国31家软件平台及其主导企业相关数据的实证研究发现,平台开放广度对主导企业绩效有正向影响;平台开放深度对主导企业绩效呈倒U型影响;不同维度平台吸引力在平台开放度影响主导企业绩效过程中的调节作用不同。其中,平台服务水平正向调节开放广度对主导企业绩效的影响,但平台用户规模和商业变现能力未呈现这一作用;平台用户基数和商业变现能力正向调节平台开放深度对绩效的影响,但平台服务水平的负向调节假设只受部分支持。  相似文献   

Android arete: Toward a virtue ethic for computational agents     

Kari Gwen Coleman 《Ethics and Information Technology》2001,3(4):247-265

Traditional approaches to computer ethics regard computers as tools, andfocus, therefore, on the ethics of their use. Alternatively, computer ethicsmight instead be understood as a study of the ethics of computationalagents, exploring, for example, the different characteristics and behaviorsthat might benefit such an agent in accomplishing its goals. In this paper,I identify a list of characteristics of computational agents that facilitatetheir pursuit of their end, and claim that these characteristics can beunderstood as virtues within a framework of virtue ethics. This frameworkincludes four broad categories – agentive, social, environmental, and moral– each of which can be understood as a spectrum of virtues rangingbetween two extreme subcategories. Although the use of a virtue frameworkis metaphorical rather than literal, I argue that by providing a frameworkfor identifying and critiquing assumptions about what a `good' computer is,a study of android arete provides focus and direction to the developmentof future computational agents.  相似文献   

A further analysis of the ethics of representation in virtual reality: Multi-user environments     

Paul J. Ford 《Ethics and Information Technology》2001,3(2):113-121

This is a follow-up article toPhilip Brey's ``The ethics of representation andaction in Virtual Reality' (published in thisjournal in January 1999). Brey's call for moreanalysis of ethical issues of virtual reality(VR) is continued by further analyzing issuesin a specialized domain of VR – namelymulti-user environments. Several elements ofBrey's article are critiqued in order to givemore context and a framework for discussion.Issues surrounding representations ofcharacters in multi-user virtual realities aresurveyed in order to focus attention on theimportance of additional discussion andanalysis of specialized aspects of VR.  相似文献
