Critical success factors for e-learning in developing countries: A comparative analysis between ICT experts and faculty

Abstract: This study identifies the critical success factors that influence the acceptance of e-learning systems in developing countries. E-learning is a popular mode of delivering educational materials in higher education by universities throughout the world. This study identifies multiple factors that influence the success of e-learning systems from the literature and compares the relative importance among two stakeholder groups in developing countries, ICT experts and faculty. This study collected 76 usable responses using the Delphi method and Analytic Hierarchy Process (AHP) approach. The results reveal 6 dimensions and 20 critical success factors for e-learning systems in developing countries. Findings illustrate the importance of curriculum design for learning performance. Technology awareness, motivation, and changing learners' behavior are prerequisites for successful e-learning implementations. Several recommendations are provided to aid the implementation of e-learning systems for developing countries which have relevance for researchers and practitioners. Limitations as well as possible research directions are also discussed.

Understanding the MOOCs continuance

Abstract: Massive Open Online Courses (MOOCs) are classes delivered in an online environment with several features that are different from previous approaches to online education The effectiveness of MOOCs is an open question as completion rates are substantially less than traditional online education courses The objective of this study is to identify factors that enhance an individual' intention to continue using MOOCs, which a limited amount of research has previously explored A research model based on the information systems continuance expectation-confirmation model is proposed and tested with data collected in a large-scale study The research model explained a substantial percentage of the variance for the intention to continue using MOOCs, which is significantly influenced by perceived reputation, perceived openness, perceived usefulness, perceived, and user satisfaction Perceived reputation and perceived openness were the strongest predictors and have not previously been examined in the context of MOOCs This study explores what influences an individual's intention to continue using MOOCsThis study examines the role of openness and reputation in the context of MOOCsReputation and openness are the strongest predictors of continuance to use MOOCs

User acceptance of wearable devices

Abstract: This study examines potential customers' perceived value of wearable devices.The results show that perceived value is a clear antecedent of adoption intention.Perceived benefit has a greater impact on perceived value than perceived risk. This study develops a research model for analyzing customers' perceived value of wearable devices. It investigates the impact of each component of perceived benefit and risk on the perceived value of wearable devices, and explores how their attributes affect customers' perceived benefit. Partial least squares was employed to test the proposed model and corresponding hypotheses on data collected from 375 survey samples (273 potential and 102 actual users). The results show that perceived value is a clear antecedent of adoption intention. Perceived benefit-including perceived usefulness, enjoyment, and social image-seems to have a greater impact on perceived value than perceived risk. Specifically, a significant difference was observed between potential users and actual users. This study discusses a number of implications and contributes useful insights for researchers as well as practitioners.

Does XBRL adoption reduce information asymmetry

Abstract: This paper examines whether or not XBRL (eXtensible Business Reporting Language) adoption reduces information asymmetry in a stock market context. Student t -tests and multiple regression analysis were employed to examine the effect of XBRL adoption on information asymmetry in the capital market. A significant and negative association exists between XBRL adoption and information asymmetry, which implies that the adoption of XBRL may lead to the reduction of the information asymmetry in the Korean stock market. In addition, the effect of XBRL adoption on reducing information asymmetry is stronger for large-sized companies than for medium-sized and small-sized companies. Based on these findings, the demand for XBRL-enabled applications and services in the capital market is expected to grow while governments should promote XBRL adoption for business reporting.

User acceptance of smart home services: an extension of the theory of planned behavior

Abstract: The purpose of this paper is to develop a comprehensive research model that can explain potential customers’ behavioral intentions to adopt and use smart home services.,This study proposes and validates a new theoretical model that extends the theory of planned behavior. Partial least squares analysis is employed to test the research model and corresponding hypotheses on data collected from 216 survey samples.,Mobility, security/privacy risk, and trust in the service provider are important factors affecting the adoption of smart home services.,To increase potential users’ adoption rate, service providers should focus on developing mobility-related services that enable people to access smart home services while on the move using mobile devices via control and monitoring functions.,This study is the first empirical attempt to examine user acceptance of smart home services, as most of the prior literature has concerned technical features.

The knowledge-creating company : how Japanese companies create the dynamics of innovation

Abstract: How has Japan become a major economic power, a world leader in the automotive and electronics industries? What is the secret of their success? The consensus has been that, though the Japanese are not particularly innovative, they are exceptionally skilful at imitation, at improving products that already exist. But now two leading Japanese business experts, Ikujiro Nonaka and Hiro Takeuchi, turn this conventional wisdom on its head: Japanese firms are successful, they contend, precisely because they are innovative, because they create new knowledge and use it to produce successful products and technologies. Examining case studies drawn from such firms as Honda, Canon, Matsushita, NEC, 3M, GE, and the U.S. Marines, this book reveals how Japanese companies translate tacit to explicit knowledge and use it to produce new processes, products, and services.

Economics of Information

Abstract: The author systematically examines one of the important issues of information — establishing the market price. He introduces the concept of «search» — where a buyer wanting to get a better price, is forced to question sellers. The article deals with various aspects of finding the necessary information.

The iron cage revisited: Institutional isomorphism and collective rationality in organizational fields (Chinese Translation)

Abstract: What makes organizations so similar? We contend that the engine of rationalization and bureaucratization has moved from the competitive marketplace to the state and the professions. Once a set of organizations emerges as a field, a paradox arises: rational actors make their organizations increasingly similar as they try to change them. We describe three isomorphic processes-coercive, mimetic, and normative—leading to this outcome. We then specify hypotheses about the impact of resource centralization and dependency, goal ambiguity and technical uncertainty, and professionalization and structuration on isomorphic change. Finally, we suggest implications for theories of organizations and social change.

Interactive home shopping: Consumer, retailer, and manufacturer incentives to participate in

Abstract: The authors examine the implications of electronic shopping for consumers, retailers, and manufacturers. They assume that near-term technological developments will offer consumers unparalleled opportunities to locate and compare product offerings. They examine these advantages as a function of typical consumer goals and the types of products and services being sought and offer conclusions regarding consumer incentives and disincentives to purchase through interactive home shopping vis-à-vis traditional retail formats. The authors discuss implications for industry structure as they pertain to competition among retailers, competition among manufacturers, and retailer-manufacturer relationships.
