Abstract

Distance education has been an important research issue of multimedia computing and communication. Since the instructional activities are implemented on cyberspace, how to control behaviors of students and to increase the degree of communication awareness have been a challenging issue. We propose a system based on the scaffolding theory. Behaviors of students are supervised by an intelligent control system, which is programmed by the instructor under our generic interface. The interface is built based on virtual reality and real‐time communication technologies. Students and instructors have their individual avatars that are controlled by a video game like navigation. Those behaviors that violate virtual campus regulations are detected and interceptive actions are performed. The proposed system is implemented on a Windows system and can be used for general purpose of distance education.

Abstract

Purpose

The purpose of this paper is to investigate the post-adoption stage of Voice over Internet Protocol (VoIP) telephony diffusion, examining usage behavior based on Shih and Venkatesh’s use-diffusion (UD) model.

Design/methodology/approach

The research model incorporates technology sophistication, complementary technologies, personal innovativeness, self-efficacy, trust propensity, media exposure, subjective norms, and word-of-mouth (WOM) referrals as UD determinants; rate of use and variety of use as usage variables; intense use, specialized use, nonspecialized use, and limited use as UD patterns; and satisfaction and intention to use future-related technologies as UD outcomes. Data used to test the research model were collected using a web-based online questionnaire form; 360 valid responses were obtained. Partial least squares, multinomial logistic regression, and analysis of variance were used to analyze data.

Findings

The results reveal that variety of use, self-efficacy, propensity to trust, media exposure, subjective norms, and WOM referrals increase rate of use, while complementary technologies, personal innovativeness, self-efficacy, media exposure, and subjective norms widen variety of use; variety of use is essential in predicting UD outcomes; when choosing limited use as the reference category, more than half of the UD determinants are capable of predicting UD patterns; and generally, intense users are more satisfied with VoIP telephony, while limited users have less intention to use future-related technologies.

Originality/value

The present study focuses on the post-adoption stage, thereby extending the frontiers of research on the diffusion of VoIP telephony. Academics can obtain some evidence of the explanatory power of the UD model in the context of VoIP telephony use, and practitioners can obtain fresh insights into the dynamics of VoIP telephony usage behavior.

Abstract

Purpose

In recent years, the partially averaged Navier–Stokes (PANS) methodology has earned acceptability as a viable scale-resolving bridging method of turbulence. To further enhance its capabilities, especially for simulating separated flows past bluff bodies, this paper aims to combine PANS with a non-linear eddy viscosity model (NLEVM).

Design/methodology/approach

The authors first extract a PANS closure model using the Shih’s quadratic eddy viscosity closure model [originally proposed for Reynolds-averaged Navier–Stokes (RANS) paradigm (Shih et al., 1993)]. Subsequently, they perform an extensive evaluation of the combination (PANS + NLEVM).

Findings

The NLEVM + PANS combination shows promising result in terms of reduction of the anisotropy tensor when the filter parameter (fk) is reduced. Further, the influence of PANS filter parameter f on the magnitude and orientation of the non-linear part of the stress tensor is closely scrutinized. Evaluation of the NLEVM + PANS combination is subsequently performed for flow past a square cylinder at Reynolds number of 22,000. The results show that for the same level of reduction in fk, the PANS + NLEVM methodology releases significantly more scales of motion and unsteadiness as compared to the traditional linear eddy viscosity model (LEVM) of Boussinesq (PANS + LEVM). The authors further demonstrate that with this enhanced ability the NLEVM + PANS combination shows much-improved predictions of almost all the mean quantities compared to those observed in simulations using LEVM + PANS.

Research limitations/implications

Based on these results, the authors propose the NLEVM + PANS combination as a more potent methodology for reliable prediction of highly separated flow fields.

Originality/value

Combination of a quadratic eddy viscosity closure model with PANS framework for simulating flow past bluff bodies.

Abstract

The concept and practice of e-services has become essential in business transactions. Yet there are still many organizations that have not developed e-services optimally. This is especially relevant in the context of Indonesian Airline companies. Therefore, many airline customers in Indonesia are still in doubt about it, or even do not use it. To fill this gap, this study attempts to develop a model for e-services adoption and empirically examines the factors influencing the airlines customers in Indonesia in using e-services offered by the Indonesian airline companies. Taking six Indonesian airline companies as a case example, the study investigated the antecedents of e-services usage of Indonesian airlines. This study further examined the impacts of motivation on customers in using e-services in the Indonesian context. Another important aim of this study was to investigate how ages, experiences and geographical areas moderate effects of e-services usage.

The study adopts a positivist research paradigm with a two-phase sequential mixed method design involving qualitative and quantitative approaches. An initial research model was first developed based on an extensive literature review, by combining acceptance and use of information technology theories, expectancy theory and the inter-organizational system motivation models. A qualitative field study via semi-structured interviews was then conducted to explore the present state among 15 respondents. The results of the interviews were analysed using content analysis yielding the final model of e-services usage. Eighteen antecedent factors hypotheses and three moderating factors hypotheses and 52-item questionnaire were developed. A focus group discussion of five respondents and a pilot study of 59 respondents resulted in final version of the questionnaire.

In the second phase, the main survey was conducted nationally to collect the research data among Indonesian airline customers who had already used Indonesian airline e-services. A total of 819 valid questionnaires were obtained. The data was then analysed using a partial least square (PLS) based structural equation modelling (SEM) technique to produce the contributions of links in the e-services model (22% of all the variances in e-services usage, 37.8% in intention to use, 46.6% in motivation, 39.2% in outcome expectancy, and 37.7% in effort expectancy). Meanwhile, path coefficients and t-values demonstrated various different influences of antecedent factors towards e-services usage. Additionally, a multi-group analysis based on PLS is employed with mixed results. In the final findings, 14 hypotheses were supported and 7 hypotheses were not supported.

The major findings of this study have confirmed that motivation has the strongest contribution in e-services usage. In addition, motivation affects e-services usage both directly and indirectly through intention-to-use. This study provides contributions to the existing knowledge of e-services models, and practical applications of IT usage. Most importantly, an understanding of antecedents of e-services adoption will provide guidelines for stakeholders in developing better e-services and strategies in order to promote and encourage more customers to use e-services. Finally, the accomplishment of this study can be expanded through possible adaptations in other industries and other geographical contexts.

Abstract

Social networking platforms such as Facebook have infiltrated the lives of many students, and as such it is natural to consider how they can be effectively used to enhance learning. This chapter provides a comprehensive review of social networking in education from a design perspective. Social networking is defined based on Boyd & Ellison’s seminal definition of connected profiles, and is distinguished from social media for the purposes of investigation. Facebook, Edmodo, and other social networking platforms are briefly described, before summarizing the wide variety of social networking usage reported in the research literature. The various benefits of social networking in education are distilled from the literature, including their capacity to facilitate community building, collaboration, reflection, and expedient access to learning. Issues surrounding the educational use of social networking are also organized into themes, for instance privacy concerns, distraction, cyber-safety, and technical constraints. The implications of findings from the social networking literature are synthesized into learning design and implementation recommendations. The chapter concludes with a discussion of open questions and areas for further investigation.

Abstract

Companies must adapt their strategies to changing market conditions. Global supply strategies have become the source of competitive advantage over the last several decades, particularly in the manufacturing industry, as US firms offshored manufacturing operations to low-cost locations such as China. The rationale was based on cost savings and other location opportunities. In the quest for a cost advantage, many firms departed from conventional outsourcing wisdom and began offshoring higher value and specialized activities such as engineering, design, testing, and research and development. As market conditions changed and cost advantages eroded, firms who offshored high value activities discovered strategic costs and unintended consequences. The extent of the challenges became more apparent as US firms began reshoring manufacturing to reposition in rapidly changing market conditions. The purpose of this research is to provide insight into the decision making process of offshoring and reshoring, to introduce a new concept to understand progressive offshoring, and to build supply chain knowledge by establishing a theoretical understanding for reshoring and strategic costs.

Abstract

The economic development of Taiwan, from a poor island colony to a world leader in electronic hardware manufacturing, has been spectacular. This study shows that the success of Taiwan may be largely attributed to the synergistic combination of two separate factors: (1) the utilization of unique social capital inherent in the Chinese family entrepreneurs, and (2) the institutional support from the government and other entities, such as Technology Parks, for the creation of scientific and technical knowledge and, most important, for the diffusion and exploitation of technology-based opportunities by these family businesses.

Abstract

Purpose

Computer based systems have great potential for delivering learning material. However, problems are encountered, such as: difficulty of Learning resource sharing, high redundancy of learning material, and deficiecy of the course brief. In order to solve these problems, this paper aims to propose an automatic inquiring system for learning materials which, utilize the data‐sharing and fast searching properties of the Lightweight Directory Access Protocol (LDAP) and JAVA Architecture for XML Binding (JAXB).

Design/methodology/approach

The paper describes an application to utilize the techniques of LDAP and JAXB to reduce the load of search engines and the complexity of content parsing. Additionally, through analyzing the logs of learners' learning behaviors, the likely keywords and the association among the learning course contents is ascertained. The integration of metadata of the learning materials in different platforms and maintenance in the LDAP server is specified.

Findings

As a general search engine, learners can search contents by using multiple keywords concurrently. The system also allows learners to query by content creator, topic, content body and keywords to narrow the scope of materials.

Originality/value

Teachers can use this system more effectively in their education process to help them collect, process, digest and analyze information.

Abstract

Purpose

An ambiguous environment indicates how rules and interests may not be outspoken or clear. In an emerging industry sector, such ambiguity may follow from different sets of rules to adapt to, changes to these rules, and how various parties surrounding a firm act based on these rules and individual interests, interaction goals, and priorities. The purpose of this paper is to describe and discuss how a company balances its relationships with others to achieve strategic intentions in an ambiguous environment. Specifically, the paper focusses on innovation in the biopharmaceutical sector in Taiwan.

Design/methodology/approach

The empirical part of the paper is based on a single case study portraying multiple parties surrounding an innovative Taiwanese biopharmaceutical firm.

Findings

The paper points to how partner selection and interaction are highly affected by the ambiguous environment. Ambiguity leads to transactional exchanges on the domestic level, while the focal firm engages in collaborative, relational interaction with international parties to accomplish innovations.

Originality/value

The paper contributes to literature on company strategies in emerging sectors with its specific focus on innovation strategies, and how a company balances ways of interacting based on an ambiguous environment. To Asian management research, contributions include an in-depth description of company-level strategizing in Taiwan.
