Building presence in an online shopping website: the role of website quality

This study explores how sellers’ website quality influences buyers’ perceived presence, which in turn affects website identification and purchase intention. The results of a conceptual model, with data collected from TaoBao, demonstrate that information and service quality are positively related to social presence, and system and service quality are positively related to telepresence. Furthermore, information and service quality increase website identification, but system quality does not. Finally, social presence positively affects website identification and purchase intention, while telepresence only positively affects website identification. These results bridge the research gap about the formation of presence in an online shopping context.     

High and low spatial frequencies in website evaluations

Statement of Relevance:

Which features of websites are important for users' perceptions regarding aesthetics or usability? This study investigates how evaluations of aesthetic appeal and usability depend on high vs. low spatial frequencies. High spatial frequencies convey information on fine details, whereas low spatial frequencies convey information about the global layout. Participants rated aesthetic appeal and usability of 50 website screenshots from different domains. Screenshots were presented unfiltered, low-pass filtered with blurred targets or high-pass filtered with high-pass filtered targets. The main result is that low spatial frequencies can be seen to have a unique contribution in perceived website aesthetics, thus confirming a central prediction from processing fluency theory. There was no connection between low spatial frequencies and usability evaluations, whereas strong correlations were found between ratings of high-pass filtered websites and those of unfiltered websites in aesthetics and usability. This study thus offers a new perspective on the biological basis of users' website perceptions.

This research links ergonomics to neurocognitive models of visual processing. This paper investigates how high and low spatial frequencies, which are neurologically processed in different visual pathways, independently contribute to users' perceptions of websites. This is very relevant for theories of website perceptions and for practitioners of web design.     

Cultivating travellers' revisit intention to e-tourism service: the moderating effect of website interactivity

The research goals of this study were to investigate how the design and service quality of the website of the public sectors affect tourists' satisfaction and continued usage intention. We collected a sample of tourists, using a survey questionnaire, and we tested the model and hypotheses using a structural equation modelling approach. E-tourism websites have unique interactive and multimedia qualities with the potential to create experiences similar to a product trial. In total, invitation messages were mailed to 2000 members of the Taiwanese backpackers' forum, of which 256 were returned completed. The findings of this study indicate that the mission of excellence in travel services will be an important strategy in e-tourism website design; an e-tourism website that allows quick navigation is likely to attract travellers. Moreover, it is important that governments adopt a knowledge-sharing culture in their relationship strategy by developing a competence for building long-term relationships with tourists.     

Measuring user satisfaction with knowledge management systems: scale development,purification, and initial test

The shift from a product-based to a knowledge-based economy has resulted in an increased demand for knowledge workers who are capable of higher-order thinking and reasoning to solve intricate problems in the workplace. This requires organizations to introduce knowledge management systems (KMS) for employees and has fueled predictions and speculations about what makes KMS effective. Unfortunately, there are very few empirical studies that examine this issue. Thus, this paper develops a validated instrument to measure user satisfaction as a surrogate measure of KMS effectiveness. Based on a survey of 147 respondents practicing mostly in four international semiconductor manufacturing companies in the Hsin-Chu Science-based Industrial Park in Taiwan suggests a 16-item instrument that measures four dimensions of user satisfaction with knowledge management systems (USKMS) is well-validated. The instrument and comprehensive model proposed in this paper would be valuable to researchers and practitioners interested in designing, implementing, and managing knowledge management systems.

Online ads in familiar and unfamiliar sites: effects on perceived website quality and intention to reuse

Electronic commerce is an integral part of most businesses today. The perceived quality of the website and whether users intend to reuse the site are of primary concern to online businesses. There are various factors that influence customers' intentions to reuse a site. In this paper, we investigate two of these factors: whether the site is familiar to the user and whether there are online advertisements on the website. The results indicate that familiarity and online ads do have an impact on quality and reuse, although it is not entirely as expected.     

Modelling the impact of mHealth service quality on satisfaction,continuance and quality of life

Understanding the impact of service quality on economic and social outcomes is critical to extend the focus of IT service research. This study evaluates the impact of quality on both these dimensions in mHealth using a cross disciplinary approach. The conceptual model is rooted in the traditional cognition–affective–conation chain but explicitly incorporates convenience, confidence, cooperation, care and concern as the primary dimensions of mHealth quality. The model is validated in the context of a business-to-consumer mHealth services using partial least squares path modelling. The results confirm that service quality has both direct and indirect impact on continuance intentions (i.e. economic outcome) and quality of life (i.e. social outcome). In this relationship, satisfaction plays the key mediating role, whereas service quality does not have any moderating effect. Research implications point to scale and sustain this new healthcare paradigm by linking service quality to satisfaction, continuance intentions and quality of life.     

Enhancement of condominium management based on the effect of quality attributes on satisfaction improvement

Condominium management (CM) businesses rely on continuous improvements to service quality (SQ) to increase consumer satisfaction (CS) and thereby improve operations. Lacking knowledge of SQ and CS results in poor efficiency. To develop cost-effective strategies for improvements, the relationship between SQ and CS must be investigated. This work proposes novel procedures to explore the relationship between identified SQ attributes and CS in the CM business. First, we conduct exploratory factor analysis to cluster intrinsically similar attributes into three constructs and identify significant attributes for subsequent assessment. Furthermore, resident satisfaction scores (RSSs) are computed to assess the relative importance rate (RIR) of investigated attributes by applying an adapted multivariate method to regress the RSSs on the performance of SQ attributes. To facilitate the decision-making process, the service-quality model evolved from the integration of an improved Kano’s approach and importance-performance analysis (IPA) is utilized to develop a prioritized strategy for satisfaction improvements in the CM business.     

The conceptualization and measurement of m-commerce user satisfaction

Many of the instruments for measuring user-perceived system quality and user information satisfaction were developed in the context of mainframe, PC and wire-based technologies of a bygone era. With the proliferation of wireless technologies, users are increasingly interfacing and interacting with mobile commerce (m-commerce) systems. It is therefore important to develop new instruments and scales, which are directly targeted for these new interfaces and applications. User satisfaction is commonly acknowledged as one of the useful proxy measures of system success. This study addresses the concern for an effective m-commerce system design by means of the conceptualization and measurement of an m-commerce user satisfaction (MCUS) construct. In this article, we introduce and define this construct of MCUS, provide empirical validation of the construct and its underlying dimensionality, develop a standardized instrument with desirable psychometric properties for measuring MCUS, and explore the measure’s theoretical and practical application. This empirically validated instrument will be useful to researchers in developing and testing m-commerce systems theories, as well as to organizations in designing better-accepted m-commerce systems.     

动态网站与静态网站的比较研究

如果网页在服务器端需要执行代码则属于动态网网站,动态网站的网页会随客户端请求的不同返回的网页也不同,也就是说传往客户端的网页是动态生成的。若网页在服务器端不需要执行代码则属于静态网站,此时传往客户端的网页是事先编好存在于服务器上的网页文件,它们是永远不变的。动态网站也可以采用静动结合的原则,适合采用动态网页的地方用动态网页,如果有必要使用静态网页,则可以考虑用静态网页的方法来实现。     

Integrating website usability with the electronic commerce acceptance model

This paper analyses the role of website usability in a B2C electronic commerce environment. The authors identify dimensions of website usability that have been examined in the literature and integrate those usability dimensions within an electronic commerce acceptance model using an e-commerce simulation. Structural equation modelling was used to analyse the relationship between several website usability and e-commerce variables (design credibility, content, interactivity, navigability, responsiveness, download delay, perceived usefulness, perceived ease of use, and satisfaction with design) as well as trust, perceived risk, and intention to transact. The results demonstrate that website usability does influence several outcomes that are important for businesses to attract and retain customers.     

The mediating effect of website quality on Internet searching behavior

The study investigates the mediating effect of website quality on Internet searching behavior. The research model incorporates three dimensions, namely (1) Internet attitudes of the Internet users, (2) website quality, including the system quality, service quality and information quality, and (3) Internet searching behavior demonstrated by the general population of Internet users. A survey instrument was used to gather data to exam the relationships in the proposed model. The collected online surveys (n = 856) are used to test the relationships among the three dimensions expressed in the proposed structural equation model. The results show that website quality has a mediating effect on Internet searching behavior. It is also discovered that there is significant correlation between Internet attitudes and website quality. This study contributes empirical data to the predominantly theoretical literature on Internet searching behavior in general and Internet attitudes and website quality in particular. It is, to a certain extent, common sense that website quality has a positive impact on Internet searching behavior. This paper takes an important step forward by detailing how website quality affects the Internet searching behavior via enhancing the effect of users’ Internet attitudes.

Intranet satisfaction questionnaire: Development and validationof a questionnaire to measure user satisfaction with the Intranet

In recent years, Intranets have become increasingly important to their companies. Substantial investments have been made to provide crucial information and workflows to employees. In this context the question of quality assurance arises: how can user satisfaction with the Intranet be measured? This article presents the development of a questionnaire to measure user satisfaction with the Intranet. After a first validation of the instrument (18 items) in an international insurance company (_N1=881)$N_1=881)$, a final set of 13 items remained. These were tested with the Intranet of a national retail company (_N2=1350)$N_2=1350)$. The final version showed a high internal consistency (Cronbach α)$\alpha )$ of .89, good item difficulties (.36–.73) and discriminatory power coefficients (.48–.73), as well as a moderate average homogeneity of .44. An exploratory factor analysis revealed two factors, “Content Quality” and “Intranet Usability”, explaining 56.54% of the variance. Meanwhile, the survey was translated into 10 languages: Chinese, English, French, German, Italian, Japanese, Portuguese, Russian, Slovenian, and Spanish.     

The measurement of user satisfaction with question answering systems

Question Answering Systems (QAS) are receiving increasing attention from IS researchers, particularly those in the information retrieval and natural language processing communities. Evaluation of an IS's success and user satisfaction are important issues, especially for emerging online service systems using the Internet. Although many QAS have been implemented, little work has been done on the development of an evaluation model for them. Our purpose was to develop a validated instrument to measure user satisfaction with QAS (USQAS). The proposed validated instrument was intended as a reference for the design of QAS from a user's perspective.
