Inference and optimal design of multiple constant-stress testing for generalized half-normal distribution under type-II progressive censoring

The generalized half-normal (GHN) distribution and progressive type-II censoring are considered in this article for studying some statistical inferences of constant-stress accelerated life testing. The EM algorithm is considered to calculate the maximum likelihood estimates. Fisher information matrix is formed depending on the missing information law and it is utilized for structuring the asymptomatic confidence intervals. Further, interval estimation is discussed through bootstrap intervals. The Tierney and Kadane method, importance sampling procedure and Metropolis-Hastings algorithm are utilized to compute Bayesian estimates. Furthermore, predictive estimates for censored data and the related prediction intervals are obtained. We consider three optimality criteria to find out the optimal stress level. A real data set is used to illustrate the importance of GHN distribution as an alternative lifetime model for well-known distributions. Finally, a simulation study is provided with discussion.     

A grounded theory research approach to building and testing TQM theory in operations management

Total quality management (TQM) has continued to develop as a strategic business improvement approach in organisations and within the Operations Management literature. Strategic TQM is a dynamic phenomenon, reflecting the complexity and technology development in the business environment. Therefore, this conception of TQM has led to significant challenges with regards to developing suitable models and research methodology where traditional, and normative research data, includes survey responses associated with deductive theory and testing. Such data, and its use, is often premised on cause and effect rationality and fails to supply deep rich data to address meanings, phenomena and complex socio-political events, which is a feature of strategic TQM.     

The influence of organizational identification on organizational knowledge management (KM)

Information technology (IT) outsourcing vendor organizations contain isolated business units whose creation and sustenance greatly facilitate business operations. But they also introduce important challenges for organizational knowledge management (KM). In this paper, based on 7 months of intensive field-work at India Inc., a leading Indian IT firm, we looked at how members’ identification with two organizations, their own and their client organization, influences their compliance with an organizational KM initiative. The findings show that members have difficulties in complying with the expectations of the organizational KM initiative owing to a stronger identification with their client organizations. At the same time, they comply readily with KM initiatives at the business unit level. The findings show that KM managers at India Inc. use the help of middle level managers in the business units in their efforts to improve members’ compliance with organizational KM. Theoretical and managerial implications of the study are discussed.     

基于资源共享与子系统交互的两阶段DEA评价方法——兼对我国“一流大学”科研绩效的评价

由于复杂的竞争环境,共享资源下的交互系统组织形式变得越来越普遍,因此有必要开发一种新的方法来衡量这些系统与子系统的效率。针对复杂系统的绩效评价问题,本文提出资源共享与子系统交互的两阶段DEA评价方法予以应对。该方法在测定系统总效率的基础上,运用Stackelberg博弈方法构建模型求解出唯一的子系统(阶段)效率。最后,将该方法应用于我国40所“一流大学”科研系统绩效评价中,评价结果反映出一定的科研系统特征,并验证了该方法的有效性。     

泛在学习环境下中美高校教师信息文化素养比较

在泛在学习环境下,高校教师作为教学的设计者、引领者、组织者和管理者,面对灵活多样的学习手段和海量的学习资源,必须具备较高的信息文化素养。比较中美信息文化素养的概念认知理解、中美高校教师信息文化素养建设标准以及中美高校教师信息素养提升途径与效果等方面的差异,学习和借鉴美国的成功经验,对从国情出发,制定出适合我国的高校教师信息文化素养标准,拓宽提升高校教师信息文化素养路径,推进我国教育现代化,实施人才强国战略具有重要意义。     

“教师资格注册制度”的理论研究与实践

教师资格注册制度已呈现出全国性常态化发展趋向。分析该制度提出的社会背景和政策背景,论述其实施的有效性,阐明其在贯彻中会出现的问题,进而提出笔者对该政策的见解,对于坚持和完善“教师资格注册制度”,具有重要的理论价值和现实意义。     

转型经济体制下创业团队的先前经验、无力感与适应能力

在资源依赖理论的基础上,从创业团队的先前经验出发,通过分析4家高科技创业企业的案例资料,考察了创业团队无力感与适应能力之间的关联性,并分析了创业团队的认知趋同性对该作用过程的影响机制,从而为新创企业提高在动态环境中的生存能力提供建议.研究表明,创业团队先前经验可以降低团队成员的无力感,从而提升团队的适应能力,且当创业团队认知趋同性越高时,无力感与适应能力的负向作用越强.     

服务人员互动风格对顾客忠诚的影响研究:关系利益的中介作用

在竞争性环境中,服务人员的有效互动尤其重要.基于此,应用关系营销理论,构建服务人员不同互动风格对顾客忠诚的影响模型,探索不同关系利益在其中的中介作用.以北京某品牌汽车4S店为背景展开调查,运用结构方程模型进行实证研究.研究结果表明,服务人员互动导向型风格既对顾客忠诚产生直接的影响,还通过顾客感知的信任利益和社会利益对其产生间接影响;任务导向型和自我导向型互动风格仅通过顾客感知的信任利益对顾客忠诚产生间接影响.     

组织文化、知识转移与新服务开发绩效:城市商业银行案例

本文是城市商业银行新服务开发的一项比较案例研究。新服务开发活动中,组织文化会影响组织内员工知识转移行为,而员工知识转移行为会影响新服务开发绩效。本文确认了地域性中小金融服务企业情境下它们之间的因果关系,并得到其具体影响方式,构建了一个三者之间相互作用的综合模型。     

管理研究者和实践者共同语言的构建

管理研究者与实践者之间存在着沟通鸿沟,这一障碍的存在既不利于管理研究的发展,又不利于管理实践的改善。基于此,从意义构建角度,提出了消除这种鸿沟的方法,即通过"差异辨识-制定规则-选择问题-形成协作"4个阶段的合作,以及构建管理研究的评价体系,减少管理研究和管理实践间的不对称性,促进两者间的有效沟通,从而实现面向实践的管理研究的良性发展。
