The role of perceived resources in online learning adoption

This study examines perceptions of adequate resources that can facilitate or inhibit students’ adoption of an online learning system, through an extension of the technology acceptance model (TAM) to include the perspectives of intra- and extra-organizational resources. The novel contribution of this study is the inclusion of internal and external-organizational factors in the aspect of perceived resources. The results of the study confirm the original TAM findings that perceived usefulness and perceived ease of use are positively associated with behavioral intention. In addition, the results also partially support that perceived resources have impacts on online learning adoption: Perceived ease of use, internal computing support, internal computing training, and external computing support have positive effects on perceived usefulness. Furthermore, internal computing support, internal computing training, external computing support, external computing training, and external equipment accessibility have positive effects on perceived ease of use. Recommendations for promoting adoption of the online learning system are subsequently discussed, along with suggestions for improving overall system design.     

Perceived network externalities and communication technology acceptance

Electronic mail (e-mail) and instant messaging (IM) systems represent two communication technologies that are potentially substitutable. A unique feature of e-mail and IM is that their value to an individual user increases as the number of other people adopting the system grows. This is referred to as a positive network externality. This externality makes it difficult for consumers to switch to other systems because of the potential loss of connectivity with network members. Further, as this externality grows, it has unintended negative consequences in the form of spim and spam. Including these three network externality effects – positive, cross-impact, and negative – the present study investigates the determinants of electronic communication system use based on an extended Technology Acceptance Model. The study findings suggest that user perceptions regarding network externalities have a positive impact on use of electronic communication systems while perceptions of problems associated with unsolicited messages and perceived usefulness of alternative systems do not significantly affect system use. This study contributes to our understanding of the factors that affect use of existing and newer alternative communication technologies.     

The benefits and dangers of enjoyment with social networking websites

Information Systems enjoyment has been identified as a desirable phenomenon, because it can drive various aspects of system use. In this study, we argue that it can also be a key ingredient in the formation of adverse outcomes, such as technology-related addictions, through the positive reinforcement it generates. We rely on several theoretical mechanisms and, consistent with previous studies, suggest that enjoyment can lead to presumably positive outcomes, such as high engagement. Nevertheless, it can also facilitate the development of a strong habit and reinforce it until it becomes a ‘bad habit’, that can help forming a strong pathological and maladaptive psychological dependency on the use of the IT artifact (i.e., technology addiction). We test and validate this dual effect of enjoyment, with a data set of 194 social networking website users analyzed with SEM techniques. The potential duality of MIS constructs and other implications for research and practice are discussed.     

Computer technology adoption in Saudi Arabia: Correlates of perceived innovation attributes

In this paper we investigate how perceived attributes of computer technology influence its rate of adoption in the workplace. In order to achieve this, the diffusion of innovation literature was reviewed looking for a set of common attributes that could be responsible for the largest rate of adoption. The literature suggests that Rogers' five attributes of innovation namely, relative advantage, compatibility, complexity, trialability, and observability explain up to 87% of the innovation rate of adoption. About 1200 knowledge workers in 56 public and private medium and large organizations across Saudi Arabia of different managerial levels and spanning a wide spectrum of industries and services have participated in this study. The findings highlight the role and direction of these factors toward computer technology adoption in developing countries. This should help decision makers in this part of the world cultivate the positively correlating factors to enhance computer technology adoption while trying to reduce the effects of the negative factors. We contend that the findings are also valuable for practitioners from western cultures in applying computer-based information systems solutions to developing countries.     

Use, perceived deterrence and the role of software piracy in video game console adoption

This paper is an exploratory study into the role of software piracy in the decision to adopt a video game console. The paper takes a rational choice perspective, where actors evaluate the deterrent cost of moral transgression before acting, to explore how users with different levels of video game usage intensity approach the adoption decision, on the grounds that more experienced users can better assess the costs and benefits of moral transgression. The study used focus groups and a literature review to develop a set of factors based on the Theory of Planned Behavior. The resulting factors were operationalized in an online survey of 285 subjects of a variety of ages and incomes. The ability to pirate console software was significant for adopters but not non-adopters. Perceived deterrence was associated with greater system use, as measured by hours of console use per week.     

Chaotic dynamics in the software market with network externalities

In this study, we built discrete-time dynamic systems to investigate the chaotic dynamics of a software market with network externalities. Monopoly and duopoly systems are considered separately. The chaotic features of both monopoly and duopoly models are verified through numerical simulations, including bifurcation diagrams, maximal Lyapunov exponent, and strange attractors. In the monopoly model, the strategy of distributing low-quality versions is evaluated. The impacts of decision parameters on the dynamics of the system are also investigated. Meanwhile, the Ott, Grebogi, and Yorke method is adopted to control chaos in the monopoly model by making moderate changes in the market evolution speed of the low-quality version software. In the duopoly model, the system dynamics are illustrated numerically. Three different cases are considered in evaluating decisions of firms regarding distribution or non-distribution of the low-quality version software. Furthermore, the compatibility parameter is examined with regards to its impacts on the dynamics of the duopoly system.     

The role of dimensions of perceived risk in adoption of corporate internet banking by customers in Iran

During the recent years, one of the issues considered by the banks in the field of internet banking is the adoption of corporate internet banking (CIB) by corporate clients. The present article tried to examine the factors affecting adoption of CIB by corporate clients based on the perceived risk theory. The research hypotheses were tested using confirmatory factor analysis and the results showed that there was a significant relationship between all the risks and intent to adopt CIB by the corporate clients of the banks. The major factors decreasing the intent to adopt internet banking include performance, privacy, security, financial, time, and social risks respectively. Based on the findings of the present study and similar studies, a comparison was made between the importance of the dimensions of perceived risk in personal and CIB and suggestions were made for decreasing the effects of these significant risks for the corporate clients to adopt CIB.     

Effects of social and technology overload on psychological well-being in young South Korean adults: The mediatory role of social network service addiction

This study examined the effects of social and information technology overload on psychological well-being. It also explored the mediating role of social network service (SNS) addiction in the hypothesized relationships between these variables. A sample of 419 college students and employees in their 20s and 30s, who were SNS users in South Korea, participated in the study. The results showed that social and information technology overload did not exert a direct impact on psychological well-being. SNS addiction served as a mediator in the relationships between these variables. The theoretical contributions and useful managerial implications of the study, with respect to reducing SNS users' addiction and improving their psychological well-being, were described.     

The effect of ethical leadership on employee social innovation tendency in social enterprises: Mediating role of perceived social capital

Although social innovation has gained prominence in policy, academic, and practitioner debates, there remains a lack of understanding of how leader aspects such as behavior and ethics contribute to fostering social innovation among employees in the social enterprise, owing primarily to a dearth of empirical research on this subject. The goal of this study is to empirically examine the effect of ethical leadership on the social innovation tendency among employees in social enterprises; also, employees' perceived social capital is hypothesized as a mediator through which the ethical leader is likely to influence their social innovation tendency. Using data collected from 189 employees associated with a variety of social enterprises, the results of structural equation modeling indicate that ethical leadership has both a direct and indirect effect on the social innovation tendency among employees, where the indirect effect of ethical leadership involves influencing the employees' perceived social capital, which subsequently influences their tendency for social innovation. Accordingly, the study offers key implications for social enterprise leaders aspiring to boost innovation in their endeavors aimed at achieving the enterprise's objective of creating positive social impact.     

Forecasting social CRM adoption in SMEs: A combined SEM-neural network method

The growth of social media usage questions the old-style idea of customer relationship management (CRM). Social CRM strategy is a novel version of CRM empowered by social media technology that offers a new way of managing relationships with customers effectively. This study aims to forecast the predictors of social CRM strategy adoption by small and medium enterprises (SMEs). The proposed model used in this study derived its theoretical support from IT/IS, marketing, and CRM literature. In the proposed Technology-Organization-Environment-Process (TOEP) adoption model, several hypotheses are developed which examine the role of Technological factors, such as Cost of Adoption, Relative Advantages, Complexity, and Compatibility; Organizational factors, such as IT/IS knowledge of employee, and Top management support; Environmental factors such as Competitive Pressure, and Customer Pressure; and Process factors such as Information Capture, Information Use, and Information Sharing; all having a positive relationship with social CRM adoption. This research applied a following two staged SEM-neural network method combining both structural equation modelling (SEM) and neural network analyses. The proposed hypothetical model is examined by using SEM on the collected data of SMEs in Kuala Lumpur, the central city of Malaysia. The SEM approach with a neural network method can be used to investigate the complicated relations involved in the adoption of social CRM. The study finds that compatibility, information capture, IT/IS knowledge of employee, top management support, information sharing, competitive pressure, cost, relative advantage, and customer pressure are the most important factors influencing social CRM adoption. Remarkably, the results of neural network analysis show that compatibility and information capture of social CRM are the most significant factors which affect SMEs' adoption of this form of customer relationship management. The outcomes of this research benefit executives' decision-making by identifying and ranking factors that enable them to discover how they can advance the usage of social CRM in their firms. Furthermore, the findings of this study can help the managers/owners of SMEs assign their resources, according to the ranking of social CRM adoption factors, when they are making plans to adopt social CRM. This study differs from previous studies as it proposes an innovative new approach to determine what influences the adoption of social CRM. By proposing the TOEP adoption model, additional information process factors advance the traditional TOE adoption model.     

Exploring the dual outcomes of mobile social networking service enjoyment: The roles of social self-efficacy and habit

Enjoyment experience has been generally regarded as a positive element which can drive various aspects of system usage. Little research has examined its potential adverse outcomes, especially in an emerging mobile services context. This study investigates the dual effects of enjoyment on mobile social networking service (Mobile SNS) usage behaviors by focusing on not only its positive outcomes but also its potential adverse consequences. In addition, this study explores the impacts of social self-efficacy and habit on these dual causal processes. A research model is developed and empirically tested using data collected from 398 mobile SNS users in China. The structural equation modeling analysis results indicate that enjoyment significantly affects both mobile SNS high engagement and mobile SNS addiction behaviors. Mobile SNS habit mediates the associations between mobile SNS enjoyment and mobile SNS addiction behaviors. Social self-efficacy directly affects mobile SNS users' enjoyment experience, and it also has important indirect impacts on the dual processes by effectively enhancing mobile SNS users' high engagement and alleviating their addiction behaviors. The theoretical and practical implications of our findings are also discussed.     

A dynamic model of electric vehicle adoption: The role of social commerce in new transportation

This research explores the adoption of electric vehicles (EVs) as a substitute for internal combustion engine vehicles (ICVs) and examines its emergence as a mobile intelligent terminal of social commerce. We present a system dynamics (SD) model incorporating fuzzy logic to simulate the adoption process. The results suggest that consumers’ vague perceptions and the dispersion of pilot EV projects have caused EV adoption to be delayed; nevertheless, the introduction of social commerce to EVs can help relieve this problem and promote EV adoption. However, the timing of introducing social commerce is critical for enhancing its positive effect on EV adoption.     

The role of perceived social capital and flow experience in building users’ continuance intention to social networking sites in China

The long-term development of social networking sites (SNSs) relies on their users’ continuance of use. This paper tested the role of perceived social capital and flow experience in driving users to continue using SNSs based on the expectation–confirmation model of information systems continuance. Using data from online surveys of social networking sites users in China, the proposed model was tested by using the Partial Least Squares (PLSs) technique. The results show that perceived bridging and bonding social capital have different role in building users’ satisfaction and continuance intention: perceived bridging social capital has remarkable influence on users’ satisfaction and continuance intention, but perceived bonding social capital has none. Flow experience has influence on users’ satisfaction but none on continuance intention. In addition, gender has impact on users’ continuance intention.     

Factors affecting e-training adoption: an examination of perceived cost,computer self-efficacy and the technology acceptance model

The objective of this paper is to highlight the role that perceived cost, computer self-efficacy and the technology acceptance model (TAM) constructs have in e-training adoption in the Nigerian civil service. With the use of the SmartPLS 2.0 M3 software, a framework that included perceived cost, computer self-efficacy and TAM constructs (perceived usefulness (PU) and perceived ease of use (PEOU)) was tested on 450 heads of departments. Scales on perceived cost, computer self-efficacy, PU and PEOU developed by previous studies were modified accordingly and used. This paper found perceived cost to have a significant effect on e-training adoption. Computer self-efficacy was statistically insignificant through PEOU. In addition, PEOU had an indirect effect through PU. Therefore, only PU of the TAM constructs indicated strong predictive strength in e-training adoption. This paper showed that with e-training adoption, facilities such as computers can be put in place, which can improve the outlook of the civil service. In addition, the cost that is usually associated with traditional training can be reduced, increasing the opportunity to invest in other aspects of the civil service which can help in adding to the overall performance. Relationships were examined in this paper, which were shown to be favourable to e-training adoption in the Nigerian civil service.     

Factors influencing the adoption of internet banking: An integration of TAM and TPB with perceived risk and perceived benefit

Online banking (Internet banking) has emerged as one of the most profitable e-commerce applications over the last decade. Although several prior research projects have focused on the factors that impact on the adoption of information technology or Internet, there is limited empirical work which simultaneously captures the success factors (positive factors) and resistance factors (negative factors) that help customers to adopt online banking. This paper explores and integrates the various advantages of online banking to form a positive factor named perceived benefit. In addition, drawing from perceived risk theory, five specific risk facets – financial, security/privacy, performance, social and time risk – are synthesized with perceived benefit as well as integrated with the technology acceptance model (TAM) and theory of planned behavior (TPB) model to propose a theoretical model to explain customers’ intention to use online banking. The results indicated that the intention to use online banking is adversely affected mainly by the security/privacy risk, as well as financial risk and is positively affected mainly by perceived benefit, attitude and perceived usefulness. The implications of integrating perceived benefit and perceived risk into the proposed online banking adoption model are discussed.     

The respective roles of perceived usefulness and perceived fun in the acceptance of microcomputer technology

Abstract

This study examined the effects of two main factors affecting microcomputer technology acceptance: perceived usefulness and perceived fun. We examined whether users are motivated to accept a new technology due to its usefulness or fun. Results of this study suggest that perceived usefulness is more influential than perceived fun in determining whether to accept or reject microcomputer technology. We also examined the impact of computer anxiety on acceptance. Results showed that computer anxiety had both direct and indirect effects on user acceptance of microcomputer technology, through perceived usefulness and fun. We also found attitude (satisfaction) to be less influential than perceived usefulness and fun. Implications for the design and acceptance of microcomputer technology and future research are discussed.

Why people use social networking sites: An empirical study integrating network externalities and motivation theory

Fast-developing social networking sites (SNS) have become the major media by which people develop their personal network online in recent years. To explore factors affecting user’s joining SNS, this study applies network externalities and motivation theory to explain why people continue to join SNS. This study used an online questionnaire to conduct empirical research, and collected and analyzed data of 402 samples by structural equation modeling (SEM) approach. The findings show that enjoyment is the most influential factor in people’s continued use of SNS, followed by number of peers, and usefulness. The number of peers and perceived complementarity have stronger influence than the number of members on perceived benefits (usefulness and enjoyment). This work also ran clustering analysis by gender, which found notable difference in both number of peers and number of members between men and women. The number of peers is an important factor affecting the continued intention to use for women but not for men; the number of members has no significant effect on enjoyment for men. The findings suggest that gender difference also produces different influences. The implication of research and discussions provides reference for SNS operators in marketing and operation.
