The Role of Task Uncertainty in IT Project Team Advice Networks

Advice seeking is often the most critical success factor in today's IT project teams. To understand how advice seekers are motivated, we integrate the antecedents of advice seeking—as defined by network theory (Granovetter, 1983)—into a cost/benefit model based on expectancy theory (Vroom, 1964). To contribute to the research on advice network formation, we integrate the role of task uncertainty—one of the defining characteristics of IT projects—into that research (Wallace & Keil, 2004). Based on a controlled quasi‐experiment, this study demonstrates that when task uncertainty is low, individuals with attractive personalities and similar demographics will be sought out for advice more frequently, regardless of their knowledge and resources (i.e., the benefits to the advice seekers). However, when task uncertainty is high, individuals with greater knowledge and access to resources are sought out more often in an advice network. These results provide clarity to prior research that has found mixed results concerning the effectiveness of the traditional antecedents to advice seeking (e.g., knowledge, power, and transactive memory) (e.g., Xu, Kim, & Kankanhalli, 2010a). In addition, project managers may choose to alter their team structure in order to optimize the advice network based on the anticipated level of IT project risk or task uncertainty.

论历史研究中的“求同存异”与“存同求异”

当前学术界很多人主张学术研究要追求创新,要求＂存同求异＂。历史研究属于学术研究,是否也应该主张＂存同求异＂？文章从历史本体研究和历史方法研究上探讨历史研究中的＂求同存异＂与＂存同求异＂,并对历史研究中＂求同＂与＂求异＂的对立统一关系进行分析。     

信息租问题探析

信息租与信息寻租概念是揭示指数和信息经济时代企业集团,尤其是跨国企业集团行为的一个核心范畴。各国企业特别是跨国企业集团,不仅利用国别民族经济之间存在技术信息、管理信息等的不对称现象追逐利润,而且将信息不对称的市场格局标准化,从而攫取信息租金,造成世界国别民族经济中产品生产份额与价值实现份额的“大分流”现象。本研究从租金理论的古典论述入手,介绍租金理论的发端与成就;进而通过信息不对称的一般模型方式介绍信息租金的概念;最后给出作者关于信息租概念的广泛理解及政策规制的结论。

Motives for sharing illness experiences on Twitter: conversations of parents with children diagnosed with cancer

A patient- and family-centred approach in paediatric health care is important because parents are involved in making key decisions about their child’s health care and advocating for the best interest of the child. Parents and family members are increasingly turning to the internet to find and actively share information about their child’s health care. Twitter is one of many online platforms used by parents of children diagnosed with cancer to share information related to their child’s cancer experience. Existing research suggests that there is a need to better understand the motives for using Twitter for sharing content about a child’s cancer experience. Furthermore, there is a lack of theoretical frameworks for characterizing those motives. In this paper, we identify key themes of tweets posted by parents of children diagnosed with cancer and align those themes with motives inspired by the well-studied Everyday Life Information Seeking framework. We propose a new motive in addition to those associated with the framework and suggest that information can be shared for endogenous reasons as well as to meet the needs of others. This paper contributes an increased understanding of motives for sharing information about a child’s cancer journey and extends a theoretical framework for building further knowledge in this area.

司马迁界定的游侠特征,只是理想的人格追求,然自侠登上社会舞台始,就走上依附于某种政治集团的道路,逐渐丧失了独立的人格,魏晋以降侠向豪强化转变;唐代侠亦豪亦侠,形态各异,提供了侠的诸性格;宋明时期的侠已世俗化,身处独行侠时,尚具有游侠精神,接受招安则沦为统治集团工具,开辟了侠的悲剧道路;清代侠已彻底官化,秦汉特立独行的侠风荡失.     

《离骚》主题探原

屈原及其作品在中国文学史上具有原型性。在《离骚》的多元多层主题中“,忠君爱国”主题局限于政治层面,不能成为与屈原的原型性人格“清洁”相对应的原主题。《离骚》的原主题是“求索”。     

效忠主管与员工工作绩效的关系:反馈寻求行为和权力距离的影响

效忠主管一直是华人组织经久不衰的议题,尽管已有文献认为员工效忠主管有助于提升其工作绩效,然而关于效忠主管通过怎样的具体机制来影响员工工作绩效却并未得到系统的阐释。本文以14家企业的360名员工为样本,探讨了效忠主管对工作绩效的影响机制,尤其是研究员工反馈寻求行为在其中的中介作用及员工权力距离的调节作用。分析结果表明,效忠主管对员工工作绩效、反馈寻求行为都有显著的正向影响;反馈寻求行为在效忠主管与工作绩效关系中起完全中介作用。另外,员工的权力距离负向调节了效忠主管与反馈寻求行为的正相关关系,即员工的权力距离越低,两者的正向相关关系越强。
