The purpose of this article is to provide insights into the effects of Internet Protocol Television (IPTV) service quality and reveal mediation effects in the process of forming the repurchase intention. This study incorporates additional theoretical construct, perceived enjoyment, to reflect IPTV characteristics using extended technology acceptance model (TAM). This study empirically investigated a research model and conducted a survey of IPTV service users. The results of this study are as follows. First, IPTV service quality is summarized as design, security, and customer service, which is supported by second-order factor analysis. Service quality had an influence on perceived usefulness, perceived ease of use, and perceived enjoyment. Second, perceived ease of use had a significant effect on perceived enjoyment, and perceived usefulness also had an effect on repurchase intention. Third, attitude, trust, and satisfaction had a positive effect on repurchase intention. To reveal the impact on repurchase intention of the IPTV service quality, this study proposes customer acceptance on IPTV service based on a modified TAM. 相似文献

The purpose of this study is to explore differences of adoption of smartwatches in China, France, and Thailand. We propose an analytical framework aggregating the technology acceptance model (TAM) elements, perceived affective quality (PAQ), mobility, availability, and trust. A quantitative approach with Smart-PLS software is used. Results show significant differences (1) between France and Thailand for availability - perceived ease of use (PEOU) and PEOU - perceived usefulness (PU) links; (2) between France and China, for PEOU - PU and trust – PU links; and finally, (3) for trust – PU, and PAQ - PEOU links between China and Thailand. The results give practitioners insights on how to successfully propose their devices in three countries, using both general strategies and specific communication systems. In China, practitioners should focus on PAQ, mobility, and trust. In Thailand, on PAQ, mobility, while differentiating based on the age and sex of their targets. In France, PAQ should be the focus, with a concern about gender with regard to communication strategies. 相似文献

This research examines the effects of type and displaying phase of trust assurances on consumers’ initial trust in an online retailer. We propose a two-stage formation process of initial online trust. The main effects of trust assurances on initial trust and the interaction between type and displaying phase of trust assurances are explored. We conducted a laboratory experiment to test our hypotheses. The results demonstrate that there exist positive effects of displaying trust assurances on initial trust. In particular, general trust assurances perform better when displayed in the information-searching stage, while specific trust assurances lead to higher initial trust when displayed in the choice stage. In the context of providing trust assurances, consumers’ knowledge of trust assurances exerts a direct and positive effect on initial trust. High knowledge level of trust assurances helps to generate the advantage of displaying assurances in the right stage. These findings have several important implications for research and practice. 相似文献

Mobile payments are the future as we move towards a cashless society. In some markets, cash is already being replaced by digital transactions, but consumers of many developing countries are slower in transition towards digital payments. This study aims to identify major determinants of consumer mobile payment adoption in India the country with second largest mobile subscribers in the world. Existing mobile payments adoption studies have predominantly utilised Technology Acceptance Model (TAM), which was primarily developed in organisational context and criticised for having deterministic approach without much consideration for users’ individual characteristics. Therefore, this study adapted meta-UTAUT model with individual difference variable attitude as core construct and extended the model with consumer related constructs such as personal innovativeness, anxiety, trust, and grievance redressal. Empirical examination of the model among 491 Indian consumers revealed performance expectancy, intention to use, and grievance redressal as significant positive predictor of consumer use behaviour towards mobile payment. Moreover, intention to use was significantly influenced by attitude, social influence, and facilitating conditions. The major contribution of this study includes re-affirming the central role of attitude in consumer adoption studies and examining usage behaviour in contrast to most existing studies, which examine only behavioural intention. 相似文献

The primary aim of this study is to examine the factors that predict end users’ intention to adopt mobile government (m-government) services in a developing country. The research is based upon a self-administered questionnaire survey of 120 current users’ in the United Arab Emirates (UAE), a leader in m-government development in the Arab world. The study employs advanced statistical techniques to test an extended the Technology Acceptance Model (TAM) by incorporating the determinants of trust, cost, social influence, variety of services, perceived usefulness in information technology and demographic profiles. The findings revealed that trust and social influence are positively associated with end users intention to adopt m-government services in the UAE. By identifying the predictors of users’ adoption of m-government, this study provides several theoretical and practical implications related to m-government service adoption. 相似文献

This paper examines empirically the factors that affect the adoption of Internet banking by Tunisian bank customers. As base model, we use the technology acceptance model (TAM) and theory of planned behavior (TPB). The model employs security and privacy, self efficacy, government support, and technology support, in addition to perceived usefulness, perceived ease of use, attitude, social norm, perceived behavior control and intention to use Internet banking. Structural equation modeling is employed to examine the inter-correlations among the proposed constructs. A survey involving a total of 284 respondents is conducted and confirmatory factor analysis was used to determine the measurement efficacies. Theoretically, this study confirms the applicability of the TAM model and TPB in predicting Internet banking adoption by Tunisian bank customers. The results allow banks' decision makers to develop strategies that can encourage the adoption of Internet banking. Banks should improve the security and privacy to protect consumers' personal and financial information, which will increase the trust of users. Government should also play a role to support bank industry by having a clear and solid law on this will ensure that customers are more confident for using Internet banking, ensuring a better Internet infrastructure and helps them to encourage users to use Internet banking. Lastly, Tunisian Banks should focus on those clients who already have a home PC, access Internet and more educated and younger since they are the most likely to adopt Internet banking. 相似文献

This study focusses on the role of trust in knowledge sharing within the context of virtual communities of practice. Trust is widely accepted as an important enabler of knowledge management (KM) processes. We conceptualise trust across three dimensions, namely: competence, integrity and benevolence; we test hypotheses as to the effect of these facets of trust on knowledge sharing by surveying an intra-organisational global virtual community of practitioners. The results indicate that all three dimensions of trust are positively related to knowledge-sharing behaviour. Trust based on the perceived integrity of the community was found to be the strongest predictor of knowledge-sharing behaviour. Our findings suggest that the dimensions of trust buttress each other; although they are theoretically distinct, they appear to be empirically inseparable. We propose that in order for knowledge sharing to be enabled, trust must concurrently exist in all three dimensions. Implication to organisations in their recruitment policy is to include competence, integrity and benevolence in their sought-for attributes of new employees. KM practitioners also have to encourage these attributes in existing employees, who are potential members of on-line communities of practice. Knowledge sharing itself was conceptualised with three components – quantity (frequency), quality (usefulness or value) and focus (the degree to which an individual feels that they engage in knowledge sharing). Of the three components, focus exhibits the most significant relationship with trust factors. This finding makes knowledge sharing less tangible than perhaps would be expected. It suggests that establishing whether knowledge has been shared is more than counting the frequency or trying to evaluate the usefulness of the shared knowledge. These aspects are important especially to management, but to the individual who shares knowledge, her feelings of having shared knowledge appear to be more important. With the current understanding that knowledge sharing is more of a human activity than technology, it is important that any information system should be assistive in boosting users’ confidence that they are indeed sharing knowledge. If the systems do not re-enforce the users’ knowledge-sharing orientation, knowledge sharing may be discouraged. Notwithstanding the point made about knowledge-sharing focus, it is necessary to take into consideration all the components of knowledge sharing to fully capture the concept. This was well indicated when the combined variable of all (rather than individual) knowledge-sharing items had the strongest correlation with trust factors.

This paper reports the results of a preliminary study of interpersonal information seeking interactions between a user and a human information source. The study showed that users specify their information needs (uncertainty) largely in terms of what they know (certainty) during the interaction. The articulated certainty and uncertainty in the interaction can be classified as utterances focusing on either the topic (what the user is talking about) or comment (how that topic fits in with the user's situation or problem). We suggest that user studies in information seeking research should conceptually realign from an emphasis on user's uncertainty- and topic-based matching to the inclusion of user's certainty and comment dimensions in order to develop a more linguistically robust, multi-dimensional approach to matching for information retrieval. 相似文献

Although mobile-related technologies are widely accepted in today's society, mobile payment in Virtual Social Networks (VSN) is not among the most widely used mobile services. This paper analyzes users’ acceptance of mobile payment in VSN. In order to analyze the level of acceptance of this technology, as well as the factors that determine its use by consumers, we have introduced a modification of the classical technological acceptance models (TRA and TAM). Thus, the study proposes and tests an integrated theoretical model, which establishes the relative importance of the key factors (external influences, ease of use, usefulness, attitude, trust and risk) in terms of the acceptance of the mobile payment system in VSN. It also analyzes the eventual moderating effect of users’ experience with similar tools. The empirical results show that the proposed behavioral model (named MPAM-VSN) is accordingly adjusted, thus showing that previous experience increases intention of use. Finally, the results obtained in this study reveal interesting implications for the diffusion of mobile payment systems in VSN. 相似文献

Artificial Intelligence (AI) has the potential to significantly impact the educational sector. One application of AI that has increasingly been applied is algorithmic grading. It is within this context that our study takes a focus on trust. While the concept of trust continues to grow in importance among AI researchers and practitioners, an investigation of trust/mistrust in algorithmic grading across multiple levels of analysis has so far been under-researched. In this paper, we argue the need for a model that encompasses the multi-layered nature of trust/mistrust in AI. Drawing on an embedded agency perspective, a model is devised that examines top-down and bottom-up forces that can influence trust/mistrust in algorithmic grading. We illustrate how the model can be applied by drawing on the case of the International Baccalaureate (IB) program in 2020, whereby an algorithm was used to determine student grades. This paper contributes to the AI-trust literature by providing a fresh theoretical lens based on institutional theory to investigate the dynamic and multi-faceted nature of trust/mistrust in algorithmic grading—an area that has seldom been explored, both theoretically and empirically. The study raises important implications for algorithmic design and awareness. Algorithms need to be designed in a transparent, fair, and ultimately a trustworthy manner. While an algorithm typically operates like a black box, whereby the underlying mechanisms are not apparent to those impacted by it, the purpose and an understanding of how the algorithm works should be communicated upfront and in a timely manner. 相似文献

The technology acceptance model (TAM) has been widely used to study user acceptance of new computer technologies. However, it does not incorporate social structure and influence as a significant factor. In this study, we ask the following questions: (i) What are the limitations of the existing TAM for studying virtual community? (ii) What is effect of social networks on user acceptance of technology for virtual community? and (iii) How can the influence of different types of social ties serve as a basis for exploring the user acceptance of technology in a virtual community? Here, we explore the possibility for extending TAM to incorporate the influence of the different types of social ties as a new theoretical construct. Preliminary analysis of data from a virtual community results show that weak and strong ties influence technology acceptance. The findings enable HCI researchers to account for influence of social ties in future investigations using TAM. 相似文献
