知识创新是企业提高核心竞争力最重要的手段之一。当今世界经济一体化,全球创新方向正在向开放式创新转变。开放式创新环境下,跨组织、跨地域的开放式创新团队成为知识创新的主要载体。社会化标签能够使团队成员按照自己对知识的认知方式进行知识交互与协作,有利于促进开放式团队知识创新。但是由于标签标注的自由性,如何建立标签之间的关联关系以更有效地支持开放式环境中基于标签的知识管理与知识创新成为该领域的关键议题。本文研究并提出了面向开放式团队知识创新的动态标签关联网方法,并对该方法进行了应用研究,通过比较实验组和对照组的应用结果,可以发现面向开放式团队知识创新的动态标签关联网方法能够动态地展示标签之间的关联关系,从而支持开放式环境中的团队知识创新。 相似文献

知识型员工的激励是一个重要的研究课题。现有研究多是从经济视角进行激励,还没有充分意识到心理因素对知识型员工积极行为的巨大作用。根据知识型员工的特点,提出了基于心理所有权理论的激励模型,并论述了不同职业发展阶段的知识型员工的激励。 相似文献

Western Canada is experiencing an unprecedented outbreak of the mountain pine beetle (MPB). The MPB has the potential to impact some of Canada's national parks by affecting park ecosystems and the visitor experience. Controls have been initiated in some parks to lessen the impacts and to prevent the beetle from spreading beyond park boundaries. We examine the perception of ecological risk associated with MPB in two of Canada's national parks, the factors affecting perceptions of risk, and the influence of risk judgments on support for controlling MPB outbreaks in national parks. Data were collected using two studies of park visitors: a mail survey in 2003 and an onsite survey in 2005. The MPB was rated as posing a greater risk to the health and productivity of park ecosystems than anthropogenic hazards and other natural disturbance agents. Visitors who were familiar with MPB rated the ecological and visitor experience impacts as negative, unacceptable, and eliciting negative emotion. Knowledge and residency were the most consistent predictors of risk judgments. Of knowledge, risk, and demographic variables, only sex and risk to ecosystem domains influenced support for controlling the MPB in national parks. Implications for managing MPB in national parks, visitor education, and ecological integrity are discussed. 相似文献

We consider a supply chain consisting of one supplier and two value-adding heterogeneous retailers. Each retailer has full knowledge about his own value-added cost structure that is unknown to the supplier and the other retailer. Assuming there is no horizontal information sharing between two retailers, we model the supply chain with a three-stage game-theoretic framework. In the first stage each retailer decides if he is willing to vertically disclose his private cost information to the supplier. In the second stage, given the information he has about the retailers, the supplier announces the wholesale price to the retailers. In response to the wholesale price, in the third stage, the retailers optimize their own retail prices and the values added to the product, respectively. Under certain conditions, we prove the existence of equilibrium prices and added values. Furthermore, we obtain the condition under which both retailers are unwilling to vertically share their private information with the supplier, as well as the conditions under which both retailers have incentives to reveal their cost information to the supplier, thus leading to a win–win situation for the whole supply chain. 相似文献

New developments in corporate information technology such as enterprise resource planning systems have significantly increased the flow of information among members of supply chains. However, the benefits of sharing information can vary depending on the supply chain structure and its operational characteristics. Most of the existing research has studied the impact of sharing downstream information (e.g., a manufacturer sharing information with its suppliers). We evaluate the benefits of sharing upstream yield information (e.g., a supplier sharing information with the manufacturer) in a two‐stage serial supply chain in which the supplier has multiple internal processes and is faced with uncertain output due to yield losses. We are interested in determining when the sharing of the supplier's information is most beneficial to the manufacturer. After proposing an order‐up‐to type heuristic policy, we perform a detailed computational study and observe that this information is most beneficial when the supplier's yield variance is high and when end‐customer demand variance is low. We also find that the manufacturer's backorder‐to‐holding cost ratio has little, if any, impact on the usefulness of information. 相似文献

知识社会学思想是布迪厄社会学理论的有机组成部分,也是理解他的整个社会学研究工作的重要线索。布迪厄借用现象学概念,对知识与社会的关系等问题进行重新诠释,并为当代知识社会学的解释模式注入了新的活力。本文认为,布迪厄对知识社会学理论的贡献主要体现在以下两个方面:第一,借鉴现象学认识论,将人类的思维原则述作“生成图式”或“信念”,用二重性表述替代了认知范畴与社会范畴的二元对立;第二,通过对“实践知识”与“科学(含社会学)知识”遵循的相异逻辑进行说明,探讨了客观真知的生成所倚赖的具体社会条件。 相似文献

Gray M, Schubert L. Sustainable social work: modelling knowledge production, transfer, and evidence‐based social work This article is a first attempt to present a model of knowledge production and transfer in social work, drawing on the expanding literature on knowledge production. It highlights features of knowledge production in social work, such as the diverse contexts in which knowledge is developed and applied. It argues that knowledge production by itself is not enough. Equally important is knowledge transfer and implementation. The literature on knowledge production highlights problems with the implementation of actually existing knowledge and the potential resistance to this implementation as highly important issues for social work research. It leads to a greater awareness of the context in which knowledge is produced and applied and creates a bridge between traditional informal and tacit ways of knowing in social work and the demands of evidence‐based practice. 相似文献

本文研究需求不确定环境下合作广告供应链中的信息共享对供应链上下游企业决策及绩效的影响。在此供应链中,上游制造商决定产品批发价格及地方性广告费用分担比例,下游零售商决定地方性广告费用的投入及产品售价。运用斯坦伯格博弈模型研究了不确定性对上下游定价和广告投入决策的影响,分析比较了有信息共享和无信息共享两种情况下供应链各成员及供应链利润。结果表明,对零售商而言,其广告水平,产品售价,及期望利润都随着广告效应的增大而增加;对制造商而言,当广告费用分担率较大时,较强的广告效应会导致零售商对广告的过度投入,从而损害制造商的利润。给定制造商广告分担率,信息共享可以提高制造商期望利润,却减少了零售商期望利润,并可能减少供应链的总体利润。给定批发价格的情况下,信息共享会提高制造商及供应链期望利润,而对零售商来讲无差别。 相似文献

针对跨组织合作形成的创新网络,构建了跨组织知识整合下的创新网络模型,仿真分析得出,组织间互补程度及知识整合效率对跨组织知识整合下的创新网络结构有一定的影响,具体表现为:组织间互补程度及知识整合效率很高时,创新网络具有较短的平均路径长度与较低的集聚系数,此时网络具有随机网络特征;组织间互补程度及知识整合效率很低时,创新网络具有较长的平均路径长度与较高的集聚系数,此时网络具有规则网络的特征;组织间互补程度及知识整合效率大小适度时,创新网络具有相对较短的平均路径长度与较高的集聚系数,因此创新网络具有"小世界"网络的特征。 相似文献
