Antecedents and consequences of mobile phone usability

We propose simplicity and interactivity as key determinants of usability.We examine the effects of usability on user satisfaction, trust, and brand loyalty.Increasing simplicity will increase interactivity and usability experience.Usability is a distal determinant of brand loyalty.Satisfaction and trust mediate the effects usability on brand loyalty. Usability is a central issue for mobile phone design and service because users need to access various functionalities via limited user interfaces (UI) often while they are on the road. In this paper, we propose simplicity and interactivity as the key determinants of mobile phone usability and assess their significance in an empirical setting. Furthermore, we examine the effects of mobile phone usability on user satisfaction, trust, and brand loyalty and provide a holistic view of the causal relationships between the proposed UI features and important organizational variables for building and maintaining long-term customer relationships. The study was conducted using survey questionnaire data collected from 310 mobile phone users in South Korea. The findings of the study confirm that simplicity and interactivity are two significant determinants of mobile phone usability and that interface simplicity is an important precondition for positive interactivity and usability experience. Our findings also show that usability is a distal determinant of brand loyalty, exerting its influence indirectly through the mediators of satisfaction and trust. We discuss the implications of the study findings for usability research and UI design.

Exploring the effect of e-WOM participation on e-Loyalty in e-commerce

Abstract The idea behind the concept of Electronic Word of Mouth (e-WOM) is very important to the visibility of individuals and businesses seeking exposure on the Internet. e-WOM is defined as “any positive or negative statement made by potential, actual, or former customers about a product or company, which is made available to a multitude of people and institutions via the Internet” [39] . The purpose of this study is to understand how electronic word of mouth influences the online shopping patterns of customers. This study draws on motivation theory and identification theory to understand how e-WOM influences online shopping behavior. The results from the empirical examination are very encouraging. The proposed research model is supported as well as the accompanying hypotheses. The findings illustrate that the intrinsic motives (e.g., desire to help other customers) are more important than the extrinsic ones (e.g., monetary rewards) as the antecedents of e-WOM participation. It was also found that personal site identification has a greater impact on e-loyalty when compared to social site identification.

Understanding music sharing behaviour on social network services

Purpose – The purpose of this paper is to understand music sharing behaviour on social networking services (SNS). This study suggests and examines a research model which focuses on the influences of user motivations, such as self‐expression, ingratiation, altruism, and interactivity, on music sharing behaviour in SNS through social motivation factors.Design/methodology/approach – Data were collected from 153 Korean SNS (i.e. Cyworld, Naver Blog, Daum Blog, and Tistory) users, who have experience in purchasing music and legally sharing it on SNS. The partial least squares method was used to analyse the measurement and structural models.Findings – The study shows that interactivity, perceived ease of use, self‐expression, social presence, and social identity are significant positive predictors of music sharing intention on SNS.Research limitations/implications – This research is significant in light of recent interest in user activities in SNS. Better understanding of the music sharing behaviour on SNS can ...

Determinants of relationship quality for IS/IT outsourcing success in public sector

Relationship has become an influential aspect for the success of IS/IT outsourcing projects. Although some studies have explored the issues of IS/IT outsourcing relationship in the past, these studies are limited to the private sectors. Whereas, studies implicate that the issues related to private and public sectors should be addressed differently. Therefore the main purpose of this study is to examine the IS/IT outsourcing relationship in the public sector by determining relationship quality factors. Based on the social exchange and the relational exchange theories a relationship model is proposed and hypotheses are tested. Ninety three IS/IT outsourcing projects in the public sector of Korea are examined and the results indicate that the outsourcing success is greatly determined by relationship quality. This study will serve as useful guidelines in understanding how to develop a successful IS/IT outsourcing relationships for IT practitioners in the public sector and the vendors undertaking those outsourced projects.

A socio-technical perspective on e-government issues in developing countries: a scientometrics approach

Many researchers have analyzed e-government literature as a whole or a specific area to focus on statistical methodologies, lessons learnt, or problem related to the area. However, no investigation from socio-technical perspective on e-government issues, in developing countries (DCs), has been carried out. Utilizing scientometrics approach, we analyzed and synthesized e-government (EG) literature that deals with the issues/topics in developing countries from the lens of socio-technical theory (STT). 145 articles from 7 core e-government journals published during the last decade were selected and reviewed for analyzing e-government literature related to developing countries. The growth pattern of e-government literature showed that e-government studies pertaining developing countries issues/topics have rapidly increased during the last decade; covering a range of topics/issues studied from socio-technical aspects. We found that e-government literature in developing countries has somewhat adopted a balanced approach and is moving away from a merely theoretical or conceptual bases toward an empirical foundation; however, the literature lacked depth and balance in terms of issues/topics discussed and methodologies applied. In the light of the findings, strengths, limitations, and future directions for e-government research in developing countries are discussed.

Impacts of organizational assimilation of e-government systems on business value creation: A structuration theory approach

Governments worldwide are eagerly anticipating a digital future with the proliferation of information system applications, but assimilation of such enterprises could be a potentially formidable challenge. Assimilation of e-government systems by organizations is important for business value creation. Despite significant investments in e-government systems, the extent to which organizations have been able to assimilate and leverage these systems varies widely. We develop a theoretical model grounded upon structuration theory and the literature on organizational information systems assimilation to investigate the impact of organizational assimilation of e-government systems on business value creation by conceptualizing the notions of IS in organizations. Based on our model, we argue that the organizational meta-structures of signification, domination, and legitimization determine aspects of organizational e-government systems assimilation behavior that may affect its value creation potential. We experimentally validate our model using a total of 367 surveys collected from public organizations currently utilizing an e-governmental system. Our results largely support the proposed model and shed new light on the factors associated with organizational assimilation of e-government systems. Finally, we isolate the organizational, technological, and inter-organizational factors that shape the meta-structures for the assimilation of e-government system. Our findings indicate that assimilation of e-government systems has a substantial impact on business value creation. We conclude by discussing the theoretical and practical implications of our findings.

Factors affecting the perceived usability of the mobile web portal services: comparing simplicity with consistency

Korean IT industry has noticed innovative changes emerging along with the increased popularity of smartphones. Increase of smartphone user has extended the smartphone business arena from simple and personal applications and content to professional software for the purpose of working in- and out of the office. In this regard, developing their services to be mobile-friendly would be important business strategies for Web business companies. The mobile data traffic in Korea had been 11.2 times increased from January 2010 to January 2011 and the average traffic per user in Korea is much higher than other countries. Usage of smartphones also has been steadily increased with the diffusion of smartphones. This may indicate that the dependency level on mobile portal service in Korea would be higher and more important than in other countries. This study analyzes the influences of UI simplicity and UI consistency on user perceptions of mobile portal services using PLS methodology. Simplicity shows a greater effect on usability and credibility than does consistency although consistency also shows a significant effect. In this regard, developing mobile Web services to be simple by following the selection and concentration strategy can be an effective strategic approach. Credibility shows a greater and direct effect on user satisfaction in this study than simplicity. But it does not mean that the perceived credibility should be treated simply as more important to user satisfaction than usability. Credibility of mobile Web services would be concreted more when the perceived usability would be developed with proper UI simplicity and consistency following the suggestion of Mann and Sahni. Also satisfaction significantly turns out to mediate the effect of credibility on loyalty. This study contributes as an earlier study on how and what the mobile Web service providers should design and provide their services.

Triple helix in the agricultural sector of Northeast Asian countries: a comparative study between Korea and China

In this paper, the agricultural innovation systems of two Northeast Asian countries—Korea and China—are investigated and compared from the perspective of triple helix innovation. Specifically, the current study examines the nature of agricultural innovation of the two countries and considers agricultural R&D investments and activities as well as the roles of university, industry, and government (UIG), which are the three units comprising the triple helix. As an empirical extension of the qualitative analysis, we collected bibliometric information of agricultural scientific publications from 1990 to 2010 and patent information from 1980 to 2010. By calculating transmission of uncertainty, which indicates collaboration among UIG, this paper tracks the relationship dynamics of the units comprising the triple helix. In addition, we analyze topics in scientific publications and patents in order to observe and compare the subareas that are the focus in the two countries. The findings reveal both commonalities and differences between the two countries, thus providing knowledge of and insights into the agricultural sector.

E-government service use intentions in Afghanistan: technology adoption and the digital divide in a war-torn country

In this article, we developed and tested an integrated model to predict intention to use e-government services by combining the concepts of technology adoption, the digital divide, and conflict literature through surveys of 360 citizens of Afghanistan. Using a partial least squares approach, we found that components of the access divide and the social divide have significant effects on intentions to use e-government services, and that the perceived intensity of civil conflict and perceived behavioral conflict moderate certain predictors of intention to use e-government services. Implications for e-government service adoption and delivery in digitally divided conflict zones in the contexts of research, policy and practice are also discussed.
