What about Passive Innovation Resistance? Investigating Adoption-Related Behavior from a Resistance Perspective

In this study, a mathematical game-based learning environment is developed on e-books for helping children reduce mathematical anxiety and improve their self-efficacy, motivation, and achievements in learning mathematics To evaluate the effectiveness of the proposed approach, an experiment was conducted on an elementary school mathematics course With quasi-experimental research, a total of 69 pupils in three classes were selected as the research subjects One class was assigned to be experimental group A, another class was experimental group B, and the third was the control group Each group consisted of 23 students In the experimental process, the three groups took pre-tests, had experimental instruction, and then took post-tests The experimental results show that the game-based e-book learning model effectively promoted the students’ learning achievement, self-efficacy, and motivation of mathematics However, no significant differences were found between the mathematical anxiety ratings of the three groups

An integrated adoption model for e-books in a mobile environment: Evidence from South Korea

This exploratory study analyzes the networked structure of theories in social sciences represented by co-occurrences on the World Wide Web. For this, co-occurrences of communication science theories were retrieved from the Web and analyzed using social network analysis tools. Several networks and node-level properties were measured to examine the relationships of theories in terms of co-occurrences. Communication science theories were grouped into four clusters. The results shed some important light on structural dynamics of communication science theories on the academic and social Web.

Theories in communication science: a structural analysis using webometrics and social network approach

This study aims to examine effects of Innovation Diffusion Model and uses and gratifications Perspectives on smartphone user's intention in the ubiquitous circumstances. To verify their effects, this study develops a research model which includes three Innovation Diffusion variables and one individual innovativeness variables as an independent variables, three the uses and gratifications variables as a moderate variables and user intention variable as a dependent variable. This study also explores interaction effects of Innovation Diffusion model and the uses and gratifications model on customers' purpose of use under ubiquitous environment. The results of a survey revealed that Relative advantages & Compatibility, Innovativeness, Information motive, and Symbolic value variables anticipated the smartphone user's intention in the ubiquitous environment. In the interaction effects between two models, the results show that some variables have the relationships at a statistically significant. The implications of these results are also discussed.

Analyzing User's Intention and Innovation Diffusion of Smartphones

This study investigated what factors affect consumers’ decision making concerning the adoption of smart TVs. For this purpose, the integrated adoption model that consists of six major constructs from the diffusion of innovation theory (DIT), the technology acceptance model (TAM), and the model of innovation resistance(MIR) was employed. To collect data, an online survey was used. Data collected were analyzed with the structural equation model (SEM). Findings showed that the innovativeness has a positive influence on the both of perceived usefulness and perceived ease of use. It was also shown that both of perceived usefulness and perceived ease of use affect the intention to use smart TVs in a positive way. The innovation resistance has a negative influence on the intention to use. The mediating role of the innovation resistance was also found. The implications of these results are discussed.

A Study on Acceptance and Resistance of Smart TVs

The current study aims to examine what determinants have influences on voluntary self-disclosure in the usage of micro-blogging. Even though the usages of micro-blogging have increased at an exponential rate in South Korea, it has been not well understood the process in which people voluntarily disclose their self-information. In this regard, we tried to examine self-disclosure process on micro-blogging based on Theory of Planned Behavior (TPB). For this purpose, attitudes towards self-disclosure, subjective norm, and perceived behavioral control were set as the antecedents to self-disclosure behavior. The influences of factors including privacy concern, playfulness, informational motivation for social participation, and relational motivation on the attitude were also investigated. The results of an online survey revealed that attitude toward self-disclosure, subjective norm, and perceived behavioral control anticipated the self-disclosure behavior at a statistically significant level. The attitude was not influenced by privacy concern, informational and relational motivation, but by playfulness. The implications of these results are also discussed.
