人的因素是安全生产中最重要的影响因素之一,员工的离职问题对安全生产绩效产生了极大的负面影响,如何提高员工的工作内嵌入度是降低员工离职率的重要途径。本文选取因变量工作内嵌入、自变量情绪智力、中介变量感知凝聚力(包括归属感和士气感两个构成维度)及调节变量大五人格特质(包括亲和性、勤勉正直性、外向性、情绪稳定性及开放学习性)建构四个变量间关系的概念模型,采用SEM模型实证检验了理论概念模型。结果显示：感知凝聚力是情绪智力与工作内嵌入关系间的中介变量,情绪智力通过影响感知凝聚力,间接促进工作内嵌入;大五人格中的五个构成维度都在情绪智力与工作内嵌入之间的关系中起正向调节作用。 相似文献

The blockchain has received significant attention from technology focussed researchers, highlighting its perceived impact and emerging disruption potential, but has been slow to engender any significant momentum within the Information Systems (IS) and Information Management (IM) literature. This study approaches the subject through an IS/IM lens developing the key themes from the blockchain based research via a comprehensive review. This analysis of the body of literature highlights that although few commercial grade blockchain applications currently exist, the technology demonstrates significant potential to benefit a number of industry wide use cases. This study expands on this point articulating through each of the key themes to develop a detailed narrative on the numerous potential blockchain applications and future direction of the technology, whilst discussing the many barriers to adoption. The study asserts that blockchain technology has the potential to contribute to a number of the UN Sustainability Development Goals and engender widespread change within a number of established industries and practices. 相似文献

This article reviews the body of research on the use and role of instant messaging (IM) in campus life, and how IM is a key part of university students' communication. IM is a synchronous form of communication, and its speed, availability information, and support for multiple conversations have made it appealing for young people. With university students, in particular, showing a heavy reliance on IM, researchers have shown great interest in how university students use IM and how it is integrated in their social and academic life. While studies are emerging in various disciplines, no attempt has been made to integrate the disparate findings and approaches. This article synthesizes key findings, provides a map of the literature, and discusses conceptual problems inherent in the study of IM and other information and communication technologies (ICTs) that will help researchers identify key areas of study and opportunities for future investigation. 相似文献

An empirical investigation of mobile banking adoption: The effect of innovation attributes and knowledge-based trust 总被引：5，自引：0，他引：5

Rapid advances in mobile technologies and devices have made mobile banking increasingly important in mobile commerce and financial services. Using innovation diffusion theory and knowledge-based trust literature, this study develops a research model to examine the effect of innovation attributes (perceived relative advantage, ease of use and compatibility) and knowledge-based trust (perceived competence, benevolence and integrity) on attitude and behavioral intention about adopting (or continuing to use) mobile banking across potential and repeat customers. Based on a survey of 368 participants (177 for potential customers and 191 for repeat customers), this study uses a structural equation modeling approach to investigate the research model. The results indicate that perceived relative advantage, ease of use, compatibility, competence and integrity significantly influence attitude, which in turn lead to behavioral intention to adopt (or continue-to-use) mobile banking. Additionally, by using multi-group analysis with t-statistics, the results found that the antecedents of attitude toward mobile banking differ between potential and repeat customers. The implications for research and practice and future research directions are discussed. 相似文献

This paper explores the much ignored but critically important subject of the perceived relationship between information and communications technology (ICT), information management (IM) and knowledge management (KM). Defining the border between ICT, IM and KM, and especially the maturity remains a highly debatable topic. These issues could be concisely summarized as being diverse and problematic and located across the spectrum of views. Prior studies suggest that even though KM is strongly entrenched and rests on the foundation of ICT and IM, very little is reported in the literature on ICT and IM as enablers to KM. From a large urban South African University engaged in numerous collaboration programs with industry, the authors gained insight into growth of KM maturity in industry groupings over a 5-year period. The authors applied an inventory developed by Kruger and Snyman [Kruger, C. J., & Snyman, M. M. M. (2007). A guideline for assessing the knowledge management maturity of organizations. South African Journal of Information Management,9(3). Electronic Journal [Online]. Available www.sajim.co.za. Accessed 15 October 2007] to a set of 86 organizations distributed over nine economic sectors in South Africa. In total 434 employees were interviewed over three group levels (operational, middle and senior management). This was achieved by having 178 senior practitioners to each interview three subjects (one in each group level). 相似文献

Despite smartphone applications (apps) being key enablers of telemedicine, telehealth, and self-monitoring, adoption issues persist for mobile healthcare (mHealth) apps. This study diverged from the traditional adoption approach and drew on more innovative theories to predict the intentions of patients for adopting apps supported by clinics. More specifically, technology identity literature was explored to make this prediction and the study surveyed 292 patients who were seated in the waiting room of a local clinic. The results suggested that perceived mobile technology identity (MTI), perceived related IT experience, and perceived self-efficacy positively influences patients’ perceived intentions to adopt mHealth apps provided by clinics or hospitals. Furthermore, the results suggested that perceived related IT experience positively influences users perceived self-efficacy and perceived MTI. However, education was found to negatively influence patients’ perceived intentions to use mHealth apps. This study contributes to the growing literature on the use of these apps in trying to elevate the quality of patients’ lives. Moreover, there are implications for mHealth-app designers who are trying to make healthcare services accessible via smartphones. 相似文献

This paper reports on the first stage of an investigation into monitoring and evaluating the impact of information management (IM) within a local government context. The overall study will utilise a combination of principles from various results-based, outcomes-based and social change approaches (Logical Framework Analysis, Most Significant Change, and Outcomes Mapping) in an attempt to move Leicestershire County Council away from a culture focused on traditional performance measurement, i.e. percentage change in use of services provided to the public, to something of real value. Interviews with 20 senior managers highlighted the important IM issues for Leicestershire County Council as a local government. These initial findings showed that maintaining high quality, trusted, and governed information and knowledge resources were of great value to the organisation. Analysis showed that 85% of senior managers interviewed considered IM to be “critical” in the achievement of organisational outcomes. Further analysis enabled the development of an initial framework indicating key areas where IM can have impact. These key areas will become the focus of further research, where applying a combination of approaches aforementioned will define the boundary partners, their specific outcomes and progress markers with possible impacts proposed. This detail will help to develop a framework for measuring the impact of IM. 相似文献
