The conclusion of this paper will be that e-sports are not sports. I begin by offering a stipulation and a definition. I stipulate that what I have in mind, when thinking about the concept of sport, is ‘Olympic’ sport. And I define an Olympic Sport as an institutionalised, rule-governed contest of human physical skill. The justification for the stipulation lies partly in that it is uncontroversial. Whatever else people might think of as sport, no-one denies that Olympic Sport is sport. This seeks to ensure that those who might wish to dispute my conclusion might stay with the argument at least for as long as possible. Secondly, the justification for the stipulation lies partly in its normativity—I have chosen an Olympic conception of sport just because it seems to me to offer some kind of desirable version of what sport is and might become. Thirdly, I give examples which show how prominent promoters of e-sports agree with my stipulation, as evidenced by their strenuous attempts to comply with it in order to join the Olympic club. The justification for the definition lies in the conceptual analysis offered—an ‘exhibition-analysis’ which clarifies the concept of sport by offering ‘construals’ of the six first-level terms. The conclusion is that e-sports are not sports because they are inadequately ‘human’; they lack direct physicality; they fail to employ decisive whole-body control and whole-body skills, and cannot contribute to the development of the whole human; and because their patterns of creation, production, ownership and promotion place serious constraints on the emergence of the kind of stable and persisting institutions characteristic of sports governance. Competitive computer games do not qualify as sports, no matter what ‘resemblances’ may be claimed. Computer games are just that—games.  相似文献

基于推荐系统中协同过滤推荐的思想, 提出两种可以利用已有答题者数据的CAT选题策略:直接基于答题者推荐(DEBR)和间接基于答题者推荐(IEBR)。通过两个模拟研究, 在不同题库和不同长度的测验中, 比较了两种推荐选题策略与两种传统选题策略(FMI和BAS)在测量精度和对题目曝光率控制上的表现, 以及影响推荐选题策略表现的因素。结果发现:两种推荐选题策略对题目曝光率的控制优于两种传统选题策略, 测量精度不亚于BAS方法, 其中DEBR侧重选题精度, IEBR对题目曝光率控制最好。已有答题者数据的特点和质量是影响推荐选题策略表现的主要因素。  相似文献

通过3个实验, 考察具身模拟在汉语肢体动作动词理解中的作用。实验1考察在整字启动下具身模拟对运动通道中箭头方向判断的影响, 发现理解肢体动作动词在运动通道中存在着动作-汉字相容效应, 汉字的具身方向与箭头方向一致促进被试对箭头方向的判断。实验2考察在整字启动下具身经验对视觉通道中字母位置判断的影响, 发现理解肢体动作动词在视觉通道中存在着动作-汉字相容效应, 汉字的具身方位与字母方位一致促进对字母方位的识别。实验3采用义符启动范式考察义符与整字的具身模拟, 发现理解汉语肢体动作动词不仅在整字层次上存在着具身模拟, 在部件层次上也存在着具身模拟。义符在汉字加工中期被激活了, 并且持续到加工晚期。整个研究表明, 汉语肢体动作动词理解是一个跨通道的具身模拟过程, 具身模拟在汉语肢体动作动词的理解中起着非常重要的作用。  相似文献

情绪具身性有着广泛的理论假说与研究证据, 从情绪外周理论到面部反馈假说、躯体标记假说再到现在的情绪具身观, 都一致认为情绪是具身的。情绪具身观认为情绪是包括大脑在内的身体的情绪, 身体的解剖学结构、身体的活动方式、身体的感觉和运动体验决定了我们怎样加工情绪。相关的行为和脑机制研究均支持了情绪加工的具身性。目前关于具身情绪的理论解释主要有镜像神经元系统假说、具身模仿论和知觉符号系统理论等。作为一种新兴的理论观点, 情绪具身观为情绪研究提供了新的视角。  相似文献

抗菌药物治疗是临床医学界普遍关切的问题。滥用抗生素的问题引起社会和政府的重视。但解决这问题需要重视调查研究,充分应用科学研究成果,制定科学合理的政策和规定。本文还从医生的角度,对经验用药、社区获得性肺炎治疗中的几个问题,介绍了国外的做法,对应用药代动力学和最低抑菌浓度结合的研究方法,包括Monte Carlo模拟的实验和临床研究,以及防突变浓度(MPC)和突变选择窗(MEw)的概念作了介绍。  相似文献

Sniffy the Virtual Rat Pro Version 2.0 is the most recent update to the Sniffy the Rat program modules. It has an extensive set of simulations related to Pavlovian and operant conditioning. Many of the standard conditioning paradigms and phenomena are contained within this program. Pavlovian effects such as blocking, overshadowing, and stimulus competition are demonstrated in the data output. Operant manipulations allow shaping the behavior of the virtual rat, observing cumulative records of interval and ratio schedules, as well as conducting operant discrimination procedures. In both Pavlovian and operant paradigms, one can generate histograms that predict the degree to which various stimuli control the virtual rat's behavior. On‐screen presentations may keep most users interested, but working with the generated data files sometimes can prove difficult. Overall, this program has a strong potential for facilitating the instruction in undergraduate conditioning courses, serving as an addendum to traditional undergraduate conditioning laboratories and as a supplement to the use of live animals.  相似文献

Administration of psychological questionnaires via the Internet has gained popularity in recent years and touts many advantages. However, before questionnaires that were originally developed as paper-and-pencil measures can be confidently administered over the Internet, it is necessary to document the equivalence of the paper and computer-generated versions [American Psychological Association. (1986). Guidelines for computer-based tests and interpretations. Washington, DC: American Psychological Association; Cohen, R.J., Swerdlik, M.E., & Smith, D.K. (1992). Psychological testing and assessment (2nd ed.). Mountain View, CA: Mayfield Publishing; Cronbach, L.J. (1990). Essentials in psychological testing (5th ed.). New York: Harper Collins; Meier, S. (1994). The chronic crisis in psychological measurement and assessment: A historical survey. San Diego: Academic Press; Schulenberg, S.E., & Yutrzenka, B.A. (2001). Equivalence of computerized and conventional versions of the Beck Depression Inventory- II (BDI-II). Current Psychology: Developmental, Learning, Personality, Social, 20, 216-230]. The current study tested this equivalence for the Obsessive Compulsive Inventory [Foa, E.B., Kozak, M.J., Salkovskis, P.M, Coles, M.E., & Amir, N. (1998). The validation of a new obsessive compulsive disorder scale: The obsessive-compulsive inventory. Psychological Assessment, 10(3), 206-214] and the Obsessive Beliefs Questionnaire-44 [Obsessive Compulsive Cognitions Working Group. (2005). Psychometric validation of the obsessive belief questionnaire and interpretation of intrusions inventory-Part 2: Factor analyses and testing of a brief version. Behaviour Research and Therapy, 43, 1527-1543] in an unselected student sample. Study results support the equivalence of these measures of obsessive compulsive disorder (OCD) symptoms and beliefs independent of administration method (paper versus secure project website). These findings create new opportunities for conducting OCD-related research online.  相似文献

Despite much research on video/computer game play, especially the relationship between such play and aggression, little attention has been directed at needs met through play. The aim of the present study was to extend Selnow’s (1984) needs’ scale, and to identify individual differences in needs among adolescents. Focus groups were conducted, followed by a content analysis, and items corresponding to emerging themes were added to reasons identified in previous research for use in a quantitative survey. Four factors emerged from a factor analysis of the results; ‘companionship’, ‘prefer to friends’, ‘fun challenge’, and ‘stress relief’, and these, with the exception of ‘companionship’, were found to be significant predictors of play.  相似文献

Although it was widely noted by researchers during the 1980s and 1990s that gender role orientation and gendered stereotyping exert a considerable influence on people’s engagement with technologies, there is little evidence of the influence of such gendered influences on contemporary technology users. The present study is based on a survey of 406 undergraduate students aged between 18 and 39 years conducted to examine whether different aspects of information and communication technology (ICT) use continue to be seen in particularly gendered terms by young adults and what reasons could be identified for any gender stereotyping. Analysis of the survey data show how issues of masculinity and femininity continue to be an important-if perhaps more subtle-influence on how young people perceive ICTs in contemporary society. In all, the findings confirm the continuing persistence of gender stereotypes as a frame of reference for ICTs.  相似文献

Two psychometric models are presented for evaluating the difficulty of the distractors in multiple-choice items. They are based on the criterion of rising distractor selection ratios, which facilitates interpretation of the subject and item parameters. Statistical inferential tools are developed in a Bayesian framework: modal a posteriori estimation by application of an EM algorithm and model evaluation by monitoring posterior predictive replications of the data matrix. An educational example with real data is included to exemplify the application of the models and compare them with the nominal categories model.This research was supported by the DGI grant BSO2002-01485.I would like to thank Eric Maris and Vicente Ponsoda for their advice, Juan Botella for providing the data for the empirical application, and three anonymous reviewers for their comments that were essential for improving the quality of the paper.  相似文献
