User acceptance of media tablets

We propose a theoretical framework for adopting a media tablet from the perspective of perceived value.An innovative design affects social image, and functionality and content have a positive impact on both perceived usefulness and enjoyment.Brand name positively affects both perceived usefulness and social image.Smartphone experience and personal innovativeness have a significant moderating effect on perceived value. Media tablets have been one of the most innovative and popular mobile devices with the rapid development of mobile computing technology. The purpose of this study is to offer a clear understanding of the overall adoption processes by starting from the characteristics of a media tablet to adoption intention via perceived value. This study investigates the relationships between the value of media tablet (e.g., usefulness, enjoyment, social image, and risk) and the product characteristics (e.g., design, functionality, contents, brand, and price). Perceived benefits including perceived usefulness, perceived enjoyment, and social image seem to have a greater impact than the level of perceived sacrifice on perceived value. Perceived usefulness is the strongest factor determining adoption intention through perceived value. An innovative design affects social image, and brand name positively affects both perceived usefulness and social image. Functionality and content have a positive influence on both perceived usefulness and enjoyment. Price positively affects perceived risk. This research also finds that smartphone experience moderates the effect of perceived usefulness on perceived value, and personal innovativeness offsets the negative effect of perceived risk on perceived value as a moderator. These findings contribute a number of implications for academia and practitioners.

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

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.

Understanding users’ continuance intention toward smartphone augmented reality applications

In spite of high expectations for augmented reality (AR) technology, many smartphone AR applications have failed and terminated their services in Korea because of low usage rates. As failures of smartphone AR applications have increased, investigating factors that influence users’ continuance intention to use the AR applications become an important topic. This study develops a theoretical model that explains continuance intention of users based on AR and motivation theories, and empirically examines the influencing factors with collected data from smartphone AR application users. The results showed that information quality was the most influencing factor for AR continuance intention among AR factors, while perceived enjoyment was not a significant antecedent. The implications of this study provide additional insights for smartphone AR researchers and developers.

User Acceptance of e-government Services: Examining an e-tax Filing and Payment System in Thailand

E-government systems effectively deliver public services to citizens as well as improve productivity and reduce costs for government departments. A pressing issue for many governments is how to expand citizen acceptance of e-government systems. Prior studies on e-tax filing and payment systems have identified various factors for successful adoption, but do not capture the basic psychological needs of users in developing countries. This study examines the determinants of citizens’ intention to adopt an e-tax filing and payment system in Thailand. The unified theory of acceptance and use of technology is integrated with self-determination theory, perceived risk, and perceived credibility to develop a model to explain the users’ acceptance of e-government services. A large-scale survey of Thai taxpayers was conducted and the results show that performance expectancy, facilitating conditions, social influence, and perceived credibility are all significant factors. Perceived autonomy and perceived competence are significant antecedents for performance and effort expectancy (EE). Perceived risk and EE surprisingly did not influence users’ intentions. Several recommendations are proposed that have an immediate application for practitioners to aide in the successful adoption of e-government services.

Exploring user acceptance of streaming media devices: an extended perspective of flow theory

Streaming media devices have recently become one of the innovative IT devices used to replace traditional smart TV sets. In order to examine user acceptance of streaming media device, this study proposes an extended research model based upon flow theory and investigates the relationship among flow, perceived usefulness, product-related characteristics (i.e., content quality, functionality, ease of use, portability), and a manufacturer-related characteristic (i.e., trust). Partial least square methodology was employed to test the proposed model and corresponding hypotheses on data collected from 305 survey samples. The results showed that flow and perceived usefulness, two mediating variables, has a significant influence on usage intention. Among the four antecedents reflecting product-related attributes, content quality has the strongest effect on flow. Interestingly, functionality and ease of use affected only perceived usefulness in an indirect way through flow. Thus, flow mediates the effect of functionality and ease of use on perceived usefulness. This study discusses a number of implications and offers insights useful for both researchers and practitioners.

Factors affecting smart learning adoption in workplaces: comparing large enterprises and SMEs

The rapid diffusion of learning through smart devices has facilitated information acquisition and improved knowledge sharing. This study analyzes the adoption and diffusion of smart learning from the human resource development (HRD) managerial perspective, based on a modified technology acceptance model which reflects perceived risk (PR) and organizational innovativeness (OI). Further, the results of a comparative analysis on large enterprises and small and medium enterprises (SMEs) reveal that their adoption of smart learning differs. First, large enterprises emphasize perceived ease of use (PEOU) as a reason for adoption, while SMEs emphasize perceived usefulness (PU). Second, while OI affects both types of enterprises, PR is statistically significant only for large enterprises. Finally, mobility and interactivity, important features of smart learning, have different effects on PEOU and PU for the two types of companies. This analysis provides useful guidance for HRD managers, solution providers, and content providers for improving workplace learning and thus creating more value for companies.

Academic domains as political battlegrounds : a global enquiry by 99 academics in the fields of education and technology

This article theorizes the functional relationship between the human components (i.e., scholars) and non-human components (i.e., structural configurations) of academic domains. It is organized around the following question: in what ways have scholars formed and been formed by the structural configurations of their academic domain? The article uses as a case study the academic domain of education and technology to examine this question. Its authorship approach is innovative, with a worldwide collection of academics (99 authors) collaborating to address the proposed question based on their reflections on daily social and academic practices. This collaboration followed a three-round process of contributions via email. Analysis of these scholars’ reflective accounts was carried out, and a theoretical proposition was established from this analysis. The proposition is of a mutual (yet not necessarily balanced) power (and therefore political) relationship between the human and non-human constituents of an academic realm, with the two shaping one another. One implication of this proposition is that these non-human elements exist as political ‘actors’, just like their human counterparts, having ‘agency’ – which they exercise over humans. This turns academic domains into political (functional or dysfunctional) ‘battlefields’ wherein both humans and non-humans engage in political activities and actions that form the identity of the academic domain.

Cyber neutralisation and flaming

ABSTRACT Individuals are increasingly subjected to flaming or negative behaviours as society becomes digitally adept. Existing research on flaming is largely fragmented and insufficient to understand what induces individuals to engage in flaming actions online. Neutralisation theory, the theory of planned behaviour (TPB), and motivational theory are integrated to develop a theoretical model to better understand flaming in virtual communities. A large-scale online questionnaire targeting individuals who had experience with flaming in a virtual community was employed to analyse the research model. The results indicate that neutralisation techniques acceptability, enjoyment, subjective norms, and low self-control significantly influence flaming. Enjoyment, low moral beliefs, subjective norms, and low self-control influence neutralisation techniques acceptability, or efforts made by individuals to rationalise their deviant behaviour. Neutralisation techniques acceptability is highly correlated with flaming in virtual communities, which has not previously been examined. Intrinsic motivation or enjoyment influences flaming, which is important because neutralisation theory and the TPB do not account for motivation. Virtual communities have a tremendous amount of influence towards an individuals rationalisation of and repeated engagement in flaming. The government, Internet service providers, the media, virtual communities, and Internet activists have an opportunity to define appropriate online behavioural standards that diminish the prevalence of flaming.

IoT Smart Home Adoption: The Importance of Proper Level Automation

The word “smart” has been used in various fields and is widely accepted to mean intelligence. Smart home service, one of the representative emerging technologies in the IoT era, has changed house equipment into being more intelligent, remote controllable, and interconnected. However, the intelligence and controllability of a smart home service are contradictory concepts, under certain aspects. In addition, the level of intelligence or controllability of a smart home service that users want may differ according to the user. As potential users of smart home services have diversified in recent years, providing the appropriate functions and features is critical to the diffusion of the service. Thus, this study examines the smart home service features that current users require and empirically evaluates the relationship between the critical factors and the adoption behavior with 216 samples from Korea. The moderating effect of personal characteristics on behavior is also tested. The results of the analysis provide various theoretical and practical implications.

High commitment human resource practices and employee behavior: a multi-level analysis

Purpose The purpose of this paper is to examine the relationship between high commitment human resource practices (HCHRPs), conceptualized at the workplace level and employees’ attitudes, including affective commitment (AC) and turnover intention (TI). The study also tests the moderating role of cooperative labor–management relations (CLMR) between HCHRPs and organizational trust (OT). Design/methodology/approach Based on social exchange theory and trust commitment theory, the authors build a research model that explains employee behavior and empirically prove the model by using samples of 407 employees from South Korea. This study uses hierarchical linear regression and cross-level hypotheses based on hierarchical linear modeling. Findings The results demonstrate the positive impact of HCHRPs on an AC and TI, through OT. However, no moderating effect of CLMR between human resource management (HRM) practices and OT is observed. Originality/value Few theory-based studies test the direct linkage between HRM practices and outcomes. This study is designed with a multi-level research method to provide a conceptually comprehensive and deeper understanding of how HRM practices work in an organization by testing the relationship between organizational practices and employees’ outcomes.
