In social networking services (SNSs), users’ unclear understanding of the large and invisible audience increases the chances of online turbulence, which is a key source of SNS-induced stress. This growing phenomenon has gained increasing attention in academia and industry due to the undesirable consequences for users and SNS platforms. In this study, we draw from the transactional model of stress to examine how audience management strategies impact online turbulence and lead to neglected unintended audience concern and lurking. We also investigate the role of self-monitoring as a stress inhibitor. We test our model with data collected from 301 SNS users. The results show that the four types of audience management strategies have different effects on online turbulence, which significantly impacts neglected unintended audience concern especially when users have high self-monitoring skills. We believe that this work contributes, both from scientific and practical standpoints, to the understanding of the interventions and stressful responses of online turbulence in SNSs.  相似文献

档案数字化是开发利用档案信息资源、创新档案服务的基础,外包则是数字化过程中非常普遍同时又颇有争议的方式。从资源依赖和交易费用的双重视角,分析档案数字化中外包的选择问题,即在什么条件下,档案部门会倾向于采用外包的方式开展数字化工作。从资源依赖视角分析人力资源、技术设备资源、场地资源的外部依赖性对数字化模式的影响;从交易费用视角则分析市场竞争、沟通协调、质量控制和安全保障四方面的影响。对广东省19家档案机构的问卷调查表明:档案部门在人力资源、技术设备上的外部依赖性,是采用外包的主要促进因素;外部场地资源的安全问题及数字化安全保障上的顾虑,则是限制外包意愿的主要因素。  相似文献

In recent years there has been a growing interest in questions related to embodiment and learning. Within the field of ‘body pedagogics’ great efforts have been made to develop theory and methodology that can deal with the corporeal aspects of experience and knowledge without adopting any form of dualistic conceptions of body/mind and organism/environment. This article connects to this body of research. The purpose is to first present a synthesis of James' radical empiricism, Dewey's transactional understanding of experience and learning and Marcel Mauss' concept of ‘body techniques’ and the notion of education embedded in it. Against the background of this theoretical development, and with a Transactional Model of Analyzing Bodying (TMAB), we then show how we can analytically come to terms with different dualistic problems that research into ‘body pedagogics’ has to deal with. We use an empirical example of dinghy sailing to create knowledge about what we learn when learning embodied knowledge, and how this learning takes place. We argue that experience is an important concept for understanding the acting knowing human being, describing how experience is organized and developed and outlining how this organization can be understood as learning. We hold that situations where someone learns to embody certain knowledge are cases of overt actions, in which we can see what kinds of relations are created and how these relations become meaningful for further action.  相似文献

A transaction log analysis of the Nanyang Technological University (NTU) OPAC was conducted to identify query and search failure patterns with the goal of identifying areas of improvement for the system. One semester’s worth of OPAC transaction logs were obtained and from these, 641,991 queries were extracted and used for this work. Issues investigated included query length, frequency and type of search options and Boolean operators used as well as their relationships with search failure. Among other findings, results indicate that a majority of the queries were simple, with short query lengths and a low usage of Boolean operators. Failure analysis revealed that on average, users had an almost equal chance of obtaining no records or at least one record to a submitted query. We propose enhancements and suggest future areas of work to improve the users’ search experience with the NTU OPAC.  相似文献
