Users’ perception of open source usability: an empirical study

The number of open source software (OSS) users has increased in recent years. No longer are they limited to technically adept software developers. Many believe that the OSS market share could increase tremendously provided OSS had systems that were easier to use. Although examples of good usable open source software exist, it is agreed that OSS can be made more usable. This study presents an empirical investigation into the impact of some key factors on OSS usability from the end users’ point of view. The research model studies and establishes the relationship between the key usability factors from the users’ perspective and OSS usability. A data set of 102 OSS users from 13 open source projects of various sizes was used to study the research model. The results of this study provide empirical evidence by indicating that the highlighted key factors play a significant role in improving OSS usability.     

Virtual item purchase behavior in virtual worlds: an exploratory investigation

Virtual worlds, such as Second Life, World of Warcraft and Everquest, have demonstrated huge economic potential. In such virtual worlds, virtual items are bought and sold between individuals for real money. However, little empirical research has been conducted into players’ purchase behavior in virtual worlds. To help us gain a better understanding of factors influencing purchase behavior in virtual worlds, we embarked on an exploratory study. Four focus groups were conducted with 24 participants, selected according to demographic and experiential characteristics. Preliminary empirical evidence suggests that factors including effort expectancy, character competency, the quality of the virtual world system, social influence, virtual item resources, personal real resources, performance expectancy, and self-actualization are important for predicting virtual item purchase behavior in virtual worlds. The results showed that virtual item purchase behavior in virtual worlds has considerable variability involving a range of factors at different stages.     

Examining end users’ ability to select business services: A conceptual framework and an empirical study

Software made from autonomous business services is gaining popularity. Now end users can build large applications by assembling a suite of services. Because some end users might have limited knowledge of their requirements and the functionality of available services, the key challenge is to find the services needed to build an application. The task of finding the services matching requirements requires specialized knowledge—knowledge of requirements and the functionality of available services—not just mere general competence. Moreover, the complexity of the requirements could also hinder the ability of end users to select services. However, there is little research into how the end users’ sophistication and requirement complexity affect their ability to avoid duplication (i.e., select the most cost-effective set of services) and select a set of services that satisfy their requirements. We provide a conceptual framework for the choice problem faced by the decision maker and develop a set of hypotheses on end user's sophistication and requirement complexity, and the impact of these factors on outcome performance—the ability to avoid duplication and select the appropriate services. Then we conduct an empirical study to test the hypotheses. Empirical results offer support for all hypotheses. Our work has several implications. We demonstrate both conceptually and empirically that end users’ naivety has a significant impact on service duplication. For a profit-maximizing service vendor, knowledge of the end user's sophistication/naivety allows there to be different pricing strategies: (1) a pure component strategy, (2) a pure bundling strategy, or (3) a mixed bundling strategy.     

An empirical study of managers’ usage intention in BI

In a changing business environment, data within and around organizations rapidly accumulate. In recent years, many organizations have implemented business intelligence (BI) to manage and refine the vast stocks of data. The effective use of BI can support managers to make faster and better decisions. The goal of this study is to investigate how to increase a manager’s intention to read information and to create reports. Based on the technology acceptance model, a research model is developed and tested to assess the factors (i.e., usefulness and ease of use) affecting a manager’s intention to use BI. In addition, the relationship between the intention to read information and the intention to create reports is linked using Dholakia and Bagozzi (D&B) model. A survey of 271 managers supports the proposed model. The empirical results show that the usefulness of BI directly and indirectly affects the intention to read information. Both the reading and creating interfaces of BI affect the intention to read information and the intention to create reports, respectively. The intention to read information positively and significantly affects the intention to create reports. Given the empirical findings, this study provides theoretical and managerial insights for organizations and managers.     

How does justice matter in online retailers’ reputation and purchase intentions: an empirical study of China

In recent years, online shopping has been proliferated around the world. Online retailers’ reputation and purchase intentions are critical for survival and profitability of any online store. Thus, this study proposes a research framework to examine the perceived justice effects on customers purchase intention and online retailers’ reputation. A confirmatory factor analysis was conducted to demonstrate the reliability and validity of the measurement model, and the structural equation modelling technique was used to test the research model. The hypothesised model was validated empirically using data collected from 383 online shopping customers in China. The results indicated that perceived procedural, distributive and interactional justice components were strong predictors of customers purchase intention and online retailers’ reputation while online retailers’ reputation had significant effects on purchase intentions. Finally, theoretical and managerial implications are also presented in the paper.     

Virtual shopping and unconscious persuasion: The priming effects of avatar age and consumers’ age discrimination on purchasing and prosocial behaviors

This study examined how operating elderly or young avatars affected shoppers’ product perceptions and purchasing behaviors. It also investigated how virtual shopping experiences translated into prosocial behavior regarding a nonprofit organization supporting the elderly. Operating elderly avatars influenced shoppers’ product choice and walking speed while shopping compared to operating younger avatars. In addition, operating elderly avatars positively affected participants’ attitudes and willingness to donate to and volunteer for a nonprofit organization supporting the elderly. Statistical interactions between avatar age and a shopper’s ageism on behavioral and persuasion outcomes were also confirmed, and these findings implied an assimilation/contrast effect influenced by a shopper’s preexisting prejudices toward the elderly.     

Understanding consumers’ continuance intention towards mobile advertising: a theoretical framework and empirical study

While issues regarding mobile advertising have captured the interest and attention of both practitioners and academics, in practice success stories are rare. An understanding of the continuance intention to use such services can provide insights into failed mobile marketing campaigns, and help to improve the implementation of future ones. Therefore, it is important to examine the underlying drivers of loyalty with regard to mobile advertising. This study uses the expectation–confirmation model in conjunction with the perspectives of value and trust to derive an integrated model to better understand the motivations behind consumers’ continued use of mobile advertising. We conducted an empirical study consisting of an online survey of 508 consumers who had experience with mobile advertising. The results show that perceived value, perceived usefulness, and satisfaction all directly influence continuance intention. Furthermore, consumer satisfaction has a crucial intervening role in the relationships that perceived value, perceived usefulness, and confirmation have with continuance intention. The theoretical and practical implications of the findings are discussed. One key limitation of this research is that the majority of respondents were students, although this group is the chief user of mobile advertising. Future research could be extended to consider other drivers of loyalty in this context, such as cultural differences and personal behavioural characteristics.     

Factors influencing consumers’ repurchase behavior on fresh food e-commerce platforms: An empirical study

The e-commerce of fresh commodities keeps being adaptive to the change of consumer consumption attitudes and behavior in the current era of global economy. In the fierce competition of the industry, how to attract and retain customers more efficiently and increase consumer repurchase behavior is a long-term concern for fresh food e-commerce platforms. This research aims to focus on how the fresh e-commerce platforms can reduce consumer conversion to other forms of purchase and increase consumer repurchase. In this paper a research model is constructed whereby a set of perceived value scales is generated to evaluate consumer repurchase behavior. Data from a sample of 515 consumers is collected through a web-based questionnaire, and structural equation modeling is used to test the research hypotheses and empirically investigate the factors and internal mechanisms influencing repurchase behavior on fresh e-commerce platforms. Results from the analysis show that the product quality and product price from the product-side, perceived ease of use, reliability, response speed and convenience from the service-side, and subjective norms of the consumer personal factors impose significant effects on consumer satisfaction. consumer satisfaction plays a key mediating role in consumer repurchase behavior. Guidance and suggestions for the operation processes of e-commerce platforms are developed based on these key factors to cultivate customer loyalty and attract potential customers more specifically. Moreover, the examination of the factors from the three dimensions promotes the e-commerce platforms to raise their service level by enhancing their supply chain as the bottom rocks of the platform enterprises.     

Longitudinal test of ePortfolio continuous use: an empirical study on the change of students’ beliefs

The electronic portfolio (ePortfolio) is learner-centred, and its effectiveness depends on the learners’ long-term use. Thus, it is proper to conduct the study from the learners’ perspectives. Currently, most research on the use of the ePortfolio is in the form of cross-sectional studies, and it is difficult to find the reasons for the changes in students’ beliefs with regard to the long-term use of the ePortfolio. Based on the longitudinal test, this study explained the students’ continuous use of ePortfolio and the changes in their beliefs. With 122 samplers in the adoption–continuous stage (t ₁–t ₂) and 117 samplers in the continuous stage (t ₂–t ₃), this study demonstrates that in continuous use stage (t ₂–t ₃), perceived ease of use still influences the users’ perceived usefulness (PU) and attitude towards the ePortfolio. Attribution significantly moderates the users’ beliefs from the adoption stage (t ₁) to the continuous use stage (t ₂). However, the moderating effect of attribution in the continuous use stage (t ₂–t ₃) is insignificant; satisfaction and attribution are the key factors driving the users’ continuous intention towards the ePortfolio rather than PU and attitude. Meanwhile, satisfaction and attribution will change because of the users’ expectation disconfirmation, and it will influence the users to continue using ePortfolio.     

Investors’ attention and overpricing of IPO: an empirical study on China’s growth enterprise market

In China, the Growth Enterprise Market (GEM) is a brand new market that provides an additional way of financing for firms with good growth potential. Whereas there has been a massive amount of stocks breaking on the first trading day since 2010, the risk of IPO’s overpricing in China’s GEM has drawn more and more attention in recent years. Based on the theory of behavioral finance and limited attention, investors’ attention may be a quite indicative determinant to the IPO overpricing. Accordingly, we collected data from Internet including online stock forums and search engines, then built multiple investors’ attention metrics that were distinct to the traditional metrics from the offline stock market. In the empirical study, we built regression models to dig out the determinants of IPO’s overpricing and found that the hybrid model containing both online metrics and financial metrics outperformed the others considerably. The adjusted R-square of the hybrid model containing both online metrics and financial metrics is as high as 82.8%, in contrast to 18.2% for the model containing only the financial metrics and 59.3% for that containing only investors’ attention.     

Dwelling in Second Life? A phenomenological evaluation of online virtual worlds

In previous research on virtual worlds, the question of whether virtual space can be evaluated just like “real world” space has not been fully addressed. This paper challenges the perceived commonsensical set of assumptions through which virtual world activities are usually unpacked and proposes a new method of evaluating virtual worlds based on Martin Heidegger’s phenomenology. Various focus groups conducted in the virtual world Second Life confirmed that a phenomenological paradigm is more appropriate to fully make sense of and leverage this new medium. Besides questioning the relevancy of dealing with virtual worlds as if they were parallel spaces, this paper, by leveraging a new conceptualization of virtual worlds, also offers suggestions for new online qualitative methodologies.     

Understanding consumers’ continuance intention towards mobile purchase: A theoretical framework and empirical study – A case of China

Although mobile purchase is convenient in the age of mobile commerce, many consumers still do not utilize mobile purchase to its full potential. From the mobile vendor’s perspective, retaining current customers and facilitating their continued purchase are crucial to create profitability and achieve a sustainable development. An understanding of the continuance intention towards mobile purchase can provide insights into mobile vendors’ marketing campaigns. Therefore, it is important to examine the determinants that impact continuance intentions of consumers for mobile purchase. Drawing upon information success model, flow theory and trust, this study proposed and empirically tested an integrated model to better understand the determinants of consumers’ continued intention to purchase on mobile sites. Empirical data from 462 users who had experience with mobile purchase were tested against the proposed research model by using structural equation modelling (SEM). The results indicated that information quality, and privacy and security concerns are the main factors affecting trust, whereas service quality is the main factor affecting flow. System quality, and privacy and security concerns affect satisfaction. Trust affects flow, which in turn affects satisfaction. These three factors together affect continued intention towards mobile purchase. The findings of this study provide several important implications for mobile commerce research and practice.     

An empirical study of customers’ perceptions of security and trust in e-payment systems

It is commonly believed that good security improves trust, and that the perceptions of good security and trust will ultimately increase the use of electronic commerce. In fact, customers’ perceptions of the security of e-payment systems have become a major factor in the evolution of electronic commerce in markets. In this paper, we examine issues related to e-payment security from the viewpoint of customers. This study proposes a conceptual model that delineates the determinants of consumers’ perceived security and perceived trust, as well as the effects of perceived security and perceived trust on the use of e-payment systems. To test the model, structural equation modeling is employed to analyze data collected from 219 respondents in Korea. This research provides a theoretical foundation for academics and also practical guidelines for service providers in dealing with the security aspects of e-payment systems.     

The role of perceived e-health literacy in users’ continuance intention to use mobile healthcare applications: an exploratory empirical study in China

ABSTRACT

In recent years, mobile healthcare applications (MHAs) have boomed, providing several new kinds of health services and methods of information transmission. However, MHA vendors face a significant challenge in attracting users to adopt software continuously. Some recent studies recognized users’ perceived e-health literacy (PEHL) as a critical factor in continuance intention, but its influence was still unclear. In this paper, based on the elaboration likelihood model (ELM), we investigated how the users’ PEHL affects their continuance intention when adopting MHAs. We distributed convenience sample questionnaires by Wechat (similar to WhatsApp) in China, where hundreds of MHAs can be downloaded, and 273 valid samples were collected. The result shows that ELM works well in this model, with six of the eight hypotheses supported. The moderating effect of PEHL is largely significant for the peripheral route but not significant for the central route. The most interesting finding is that, with regard to continuance adoption, PEHL has a positive relationship with users’ satisfaction. Possible reasons are discussed, such as there could be a moderator on this relationship. Limitations, future studies and implications for theory, practice and policy are also given.     

Are you ready for knowledge sharing? An empirical study of virtual communities

This study aimed to explore the relationship between knowledge sharing intentions and the perceptions of individual technology users who are members of virtual communities. We characterized learners' perceptions of new technological products or services by including both an individual's psychological state of readiness to accept technology and also compatibility as factors affecting technology acceptance. By adopting virtual communities as samples for this empirical study, the Technology Acceptance Model, Technology Readiness Index, and the factor of compatibility were integrated in order to explore users' perceptions of technology. We analyzed the responses of 218 participants from these virtual communities using structural equation modeling. The empirical results showed that an individual's positive attitude, such as optimism, toward the Technology Readiness Index positively affects acceptance of technology; an individual's negative perception of the Technology Readiness Index, such as discomfort, has a negative effect on his or her sense of the perceived ease of technology and compatibility in regard to prior experience and technology. A sense of insecurity toward the new technology also showed a significant effect on the individual's perceptions of the usefulness of technology. The results of this research demonstrated that improving an individual's degree of adaptability to technology could increase knowledge-sharing intentions in virtual communities. Meanwhile, the degree of the individual's discomfort with technology did not hinder knowledge-sharing intentions.     

Determinants of users’ intention to adopt m-commerce: an empirical analysis

The fast-growing penetration of mobile devices and recent advances in mobile technologies have led to the development of increasingly sophisticated services such as m-shopping for goods or services and m-payment. However, although the number of mobile subscribers is increasing, levels of actual m-commerce activities in many cases remain low. Determining what influences users’ intention to use m-commerce is therefore of growing importance. The purpose of this study was to investigate possible factors. To this aim, we developed a conceptual user adoption model based on technology acceptance model variables and on specific factors such as social influence, personal innovativeness, customization, and individual mobility. The empirical results show that social influence and customization significantly affect perceived usefulness; mobility, customization, and personal innovativeness significantly affect perceived ease of use; and perceived usefulness and perceived ease of use have a direct positive effect on behavioral intention.     

Changing information retrieval behaviours: an empirical investigation of users’ cognitive processes in the choice of location-based services

The introduction of smartphones and the accompanying profusion of mobile data services have had a profound effect on individuals’ lives. One of the most influential service categories is location-based services (LBS). Based on insights from behavioural decision-making, a conceptual framework is developed to analyse individuals’ decisions to use LBS, focusing on the cognitive processes involved in the decision-making. Our research is based on two studies. First, we investigate the use of LBS through semi-structured interviews of smartphone users. Second, we explore daily LBS use through a study based on diaries. The findings highlight that the decision to use LBS can be described by either a comparative mode based on the value of LBS in relation to other available options, or an intuitive mode in which past experiences trigger the use of heuristics. These modes in turn have positive influences on the continuance of LBS use and indicate changes in individuals’ information retrieval behaviours in everyday life. In particular, the distinct value dimension of LBS in specific contexts of use changes individuals’ behaviours towards accessing location-related information.
