The purpose of this study is to conceptualize a digital library acceptance model and its validation. Based on the extant literature and interviews with experts, a sixty-three statement questionnaire was developed and a survey was conducted to test the proposed model. The target population included library professionals and users from academic institutions in India including faculty, graduate students, and undergraduate students. These sixty-three statements were categorized into seventeen dimensions on the basis of the Unified Theory of Acceptance and Use of Technology model and two information success models. The model was tested using exploratory and confirmatory factor analysis. The findings suggest that digital libraries can become more useful and acceptable to targeted user groups when they are developed in accordance with four major factors: systemic aspects, informational aspects, perception of the relevant social group, and user learning. This study is unique as it is the first time such a model has been developed for digital libraries with respect to social construction. 相似文献

利用三维运动学模型模拟研究行星际激波与共转高速流(CHSS)的相互作用。通过改变模式输入条件中耀斑的强度及位置,研究相互作用对CHSS到达地球时间的影响,以及对激波的传播和激波形态的影响。模拟结果表明:(1)行星际激波与CHSS相互作用对彼此到达地球时间都有影响;(2)有激波比没有激波条件下的CHSS到达地球时间要早,且CHSS到达地球时间与驱动激波的耀斑的强度以及扰动源区的位置有关,耀斑的强度越大、扰动源区与CHSS前的电流片的经度距离越近,则CHSS到达地球时间也越早;(3)激波在以CHSS为背景的太阳风中传播比在没有CHSS的均匀背景场中传播得快,但激波与CHSS的相互作用对激波到达地球时间的影响远没有对CHSS到达地球时间的影响大;(4)当耀斑位于CHSS前电流片的东边时,耀斑驱动的激波与CHSS相互作用可能会使激波形态发生改变,呈双峰结构。 相似文献

Cybersecurity is a serious threat to information technology (IT) systems, with most organisations now relying on their IT systems to function day-to-day. Therefore, it is crucial that organisations ensure they are protected. This research investigates the emotional and coping responses of employees towards a cyber-attack. Data was collected through an in-depth case study approach (24 semi-structured interviews) conducted at a global manufacturing company, along with primary observations and a corpus of secondary materials. Our data analysis applied a grounded approach which was then refined using an emotion theoretic lens with the application of Technology Threat Avoidance Theory (TTAT). Drawing on structural appraisal theory, our findings indicate the IT security team in the case study oscillated between positive problem-focused coping and negative emotion-focused coping. A key explanatory feature or turnaround mechanism that mediated this oscillation was senior management empathy and resource mobilization. Building on the analyses, a conceptual model is developed called the Transformation of Coping through Empathic Leadership (T-CEL). The research suggests the crucial role that senior management play in transforming the emotional and coping capabilities of employees through their intervention and support. The study extends the IS Security theoretical background through a TTAT-lens for the analysis of cyber-attack incidents. 相似文献

This article describes how the Business Informatics program at Northern Kentucky University (NKU) has evolved and, in so doing, has addressed the call from the IS 2010 Curriculum Design Committee listed below. The article initiates this discussion with a discussion of the basic systems perspective that underlies the information systems discipline. The next section presents a review of the creation of a College of Informatics (COI) at NKU that included the strategic decision of structurally moving the Information Systems Department from the College of Business. The authors then document the perceptual shift this decision created as the Information Systems Department changed its name to Business Informatics and took on the goal of expanding the discipline beyond the business domain with partnerships across campus. A short discussion on the progress made in implementing this vision is detailed. The article closes with a discussion of problems and opportunities generated. 相似文献

20世纪末以来,西方高等教育质量管理导入IS09000并不是一个模糊的景象,西方高等教育机构在传统学术质量管理受到国际化与产业化绩效评估的挑战时,确实认为IS09000可以解决一些问题,但他们更愿意寻求更适宜大学的质量管理方式。在西方高等教育理论的视野当中,IS09000与高等教育的质量管理是一个曾经掀起争论但在现实中已经沉寂的事物。真正的大学只是将教务管理、后勤服务交给IS09000,在教学与科研上则保持学术标准。积极导入IS09000并能在导入过程中获得好处的是一些非正规高等教育机构和新兴高等教育机构,因为在传统学术的竞争中处于下游的它们能在标榜导入IS09000的过程中更好地赢得市场竞争。 相似文献

1998年我国政府实行积极财政政策,国债规模逐年攀升。但是庞大的国债规模。并没有对私人投资产生明显的挤出效应。尽管如此,政府制定政策时还是应当慎重,应该适当控制国债的增长率,转变财政支出的结构。本文从挤出效应的作用机制入手,通过模拟我国的IS-LM模型,从实证的角度论证了国债没有对私人投资产生明显的挤出效应。 相似文献

Response to large-scale emergencies is a cooperative process that requires the active and coordinated participation of a variety of functionally independent agencies operating in adjacent regions. In practice, this essential cooperation is sometimes not attained or is reduced due to poor information sharing, non-fluent communication flows, and lack of coordination. We report an empirical study of IT-mediated cooperation among Spanish response agencies and we describe the challenges of adoption, information sharing, communication flows, and coordination among agencies that do not share a unity of command. We analyze three strategies aimed at supporting acceptance and surmounting political, organizational and personal distrust or skepticism: participatory design, advanced collaborative tools inducing cognitive absorption, and end-user communities of practice. 相似文献

全面协同:创新致胜之道——技术与非技术要素全面协同机制研究 总被引:3,自引:2,他引:3
在分析总结国内外有关技术创新过程中协同问题研究现状的基础上,基于全面创新管理(TIM)的崭新理论视角探讨了技术创新过程中技术、战略、组织、文化、制度、市场等各关键要素的协同问题,首次提出了各创新要素全面协同的概念,并提出了C3IS五阶段全面协同过程模型,认为实现全面协同一般来说应该经过沟通、竞争、合作、整合、协同五个阶段。对于了解企业技术创新的过程,促进技术与各非技术要素的协同,从而提升创新绩效具有现实指导意义。 相似文献
