The adoption of mobile healthcare by hospital's professionals: An integrative perspective

The adoption rate of mobile healthcare is relatively low in the hospital. In practice, a study of how healthcare professionals adopt mobile services to support their work is imperative. An integration of TAM and TPB, concerning both technological and organizational aspects, is important for understanding the adoption of mobile healthcare. However, mobile healthcare is a wireless device which is often used in a voluntary motive. Service provisions for pervasive and timely usage and individual psychological states are critical in determining its use. Accordingly, perceived service availability (PSA) and personal innovativeness in IT (PIIT) may be the important drivers to be included in TAM and TPB. This study thus proposed such a research framework from a broader and integrative perspective. The empirical examination showed high predictive power for adoption intention and the influential role of these important variables.     

How information-sharing values influence the use of information systems: An investigation in the business intelligence systems context

Although the constituents of information systems (IS) success and their relationships have been well documented in the business value of information technology (IT) and strategic IS literature, our understanding of how information-sharing values affect the relationships among IS success dimensions is limited. In response, we conduct a quantitative study of 146 medium and large firms that have implemented a business intelligence system in their operations. Our results highlight that in the business intelligence systems context information-sharing values are not directly linked to IT-enabled information use, yet they act as significant moderators of information systems success dimensions relationships.     

Exploring the effects of direct experience on IT use: An organizational field study

Empirical studies have investigated the effect of attitude and behavior on IT acceptance in organizations but yielded ambiguous results. Possibly they have not effectively accounted for the moderating effects of experience gained through direct interaction with the target technology. We examined the moderating effect of the length of direct experience on IT acceptance relationships and constructs. Using multi-group invariance analysis, we demonstrated that relationships between key IT acceptance constructs differed, depending on the user's experience. The incorporation of direct experience can lead to convergent results and contribute to further understanding of the process. We discuss some implications from the knowledge that IT use is a dynamic process and suggest that IT management must account for direct experience in their decision making.     

Problems in the interplay of development and IT operations in system development projects: A Delphi study of Norwegian IT experts

Context

The assumption of the presented work is that the ability of system developers and IT operations personnel to cooperate effectively in system development projects has great impact on the quality of the final system solution, as well as on the service level of its subsequent operation.

Objective

The present research explores the interplay of system development and IT operations and the challenges they are meeting. We are especially interested in identifying problems encountered between these two parties in system development projects.

Method

We identify and rank problems by using a ranking-type Delphi study. We involved 42 Norwegian IT experts and split them into three expert panels: system developers, IT operations personnel and system owners. We then guided them through the three phases of the Delphi method - brainstorming, reduction and ranking.

Results

A comprehensive list of 66 problems, organized into seven groups, is compiled. Through a selection and ranking procedure, the panels found the following to be the six most serious problems in the interplay of system development and IT operations: (1) IT operations not being involved in the requirements specification; (2) poor communication and information flow; (3) unsatisfactory test environments; (4) lack of knowledge transfer; (5) systems being put into production before they are complete; and (6) operational routines not being established prior to deployment.

Conclusion

The sheer amount and variety of problems mentioned and the respondents’ explanations confirm that this interplay needs attention; the parties agree that they do not cooperate effectively in development projects. The results imply that IT operations should be regarded as an important stakeholder throughout several systems development activities, especially requirements analysis, testing and deployment. Moreover, such involvement should be facilitated by an increased focus on enhancing cooperation and communication.     

A comparative study of important risk factors involved in offshore and domestic outsourcing of software development projects: A two-panel Delphi study

We investigated the risk factors of outsourced software development. Our first objective was to create empirically generated lists of risk factors for both domestically- and offshore-outsourced projects. Our second objective was to compare these two contexts: how do the risk factors change and which ones are most important in each. To address these objectives, we conducted two Delphi surveys to identify the important risk factors from a client perspective, in domestic and offshore settings. We qualitatively compared the results of the surveys to identify similarities and differences across their risk profiles. We identified three types of risks: those that appeared in both contexts; those that appeared in both but were exacerbated in the offshore context; and those that were unique to the offshore context. Our findings suggested that traditional project management risks were important in both contexts; however, the offshore context seemed to be more vulnerable to some traditional risks as well as factors that were unique to it.     

Understanding use continuance in virtual worlds: Empirical test of a research model

We decided to examine why people continue to use virtual worlds by studying a real example: the popular virtual world of Second Life. This involved building and testing a model of virtual worlds based on habit from both the habit/automaticity and instant automaticity perspectives, the latter based on utilitarian and hedonic goals. The results (for a sample of 339 users) suggested that continuance intention for the virtual world was driven by perceived usefulness, enjoyment, and both perspectives of automatic behavior, which together provide considerable explanatory power for both habit and continuance intention. We conclude with implications for practice in this new area of inquiry.     

Teenagers in social virtual worlds: Continuous use and purchasing behavior in Habbo Hotel

Social virtual worlds (SVWs) have become important environments for social interaction. At the same time, the supply and demand of virtual goods and services is rapidly increasing. For SVWs to be economically sustainable, retaining existing users and turning them into consumers are paramount challenges. This requires an understanding of the underlying reasons why users continuously engage in SVWs and purchase virtual items. This study builds upon Technology Acceptance Model, motivational model and theory of network externalities to examine continuous usage and purchase intention and it empirically tests the model with data collected from 2481 Habbo users. The results reveal a strong relationship between continuous usage and purchasing. Further, the results demonstrate the importance of the presence of other users in predicting the purchase behavior in the SVW. Continuous SVW usage in turn is predicted directly by perceived enjoyment and usefulness while the effect of attitude is marginal. Finally, perceived network externalities exert a significant influence of perceived enjoyment and usefulness of the SVW but do not have a direct effect on the continuous usage.     

Factors driving the adoption of m-learning: An empirical study

Even if m-learning is spreading rapidly in many regions of the world, research addressing the driving factors of m-learning adoption is in short supply. Built on the Technology Acceptance Model, this paper proposes a hypothesized model of m-learning adoption. Employing structural equation modeling technology, the model was assessed based on the data collected from 230 participants using a survey questionnaire. Results indicate that perceived near-term/long-term usefulness and personal innovativeness have significant influence on m-learning adoption intention, while perceived long-term usefulness significantly affects the perceived near-term usefulness. Personal innovativeness is a predictor of both the perceived ease of use and perceived long-term usefulness as well. Of all variables, the perceived long-term usefulness contributes to the most influential predictor of m-learning adoption. The model accounts for approximately 60.8% of the variance of behavioural intention. The results indicted that offing high-quality contents complying with students’ future targets is key to the success of m-learning in China. Both theoretical and practical implications are discussed.     

Understanding the interplay of social commerce affordances and swift guanxi: An empirical study

Prior studies highlight consumer behavior in social commerce from the perspective of relational exchange, while culture-driven aspects have been neglected. Given cultural uniqueness in China, this study develops a research model to explore the effects of key social commerce affordances on swift guanxi dimensions and subsequent purchase intention. Data from 450 agricultural product consumers in social commerce were used in PLS analysis for testing the proposed research model. The results indicate that interactivity, stickiness, and word of mouth exert positive effects on mutual understanding, reciprocal favor, and relationship harmony, to various degrees. In turn, swift guanxi dimensions are determinants of consumers’ purchase intention in social commerce.     

An empirical study of payment technologies,the psychology of consumption,and spending behavior in a retailing context

Our study investigates differences in spending behavior among consumers using three alternative payment technologies: cash, credit cards, and stored value contactless smart cards. We provide a deeper understanding of how different payment mechanisms directly impact consumer spending behavior in a retailing context, their influences on customers’ psychology of consumption, and perceptions of payment technologies. We show that the payment process can do so by significantly affecting the subjective awareness of spending only. In contrast, the source of money can affect perceived payment security only. Both perceived security and convenience have little effect on spending behavior.     

Web-enabled wireless technology: an exploratory study of adoption and continued use intentions

This study builds upon previous research by comparing and contrasting the decision to adopt wireless technologies with the decision to continue to use wireless technologies. In the context of web-enabled cell phones, we propose, test and compare the predictive ability of two value-based models using a multi-group analysis. The findings suggest that regardless of whether an individual was choosing to adopt or continue to use a web-enabled cell phone, perceived usefulness, enjoyment and perceived fee influenced perceived value. In turn, perceived value influenced the adoption or continued use decision. Technicality had a significant negative effect on perceived value in the context of continued use, but not for adoption. Our results also suggested a shift in the importance of benefits in the formation of perceived value; perceived usefulness played a greater role for adopters, while enjoyment played a better role for continued users. Lastly, our results indicated that uncertainty avoidance did not mediate the relationship between perceived value and intention in either the continued use or adoption contexts, while habit was significant in its mediation of the relationship between perceived value and continued use intention. Collectively, habit and perceived value explained 71% of the variation in continued use intention.     

Ethical behavior issues in software use: An analysis of public and private sectors

Ethical issues related to information systems are important to the information technology (IT) professionals. These issues are also significant for organizations and societies. Although considerable literature on IT and related ethical issues exists, a review of this literature has found little empirical research on ethical practices within the government and private sector organizations. Therefore, the objective of this paper is to draw inferences regarding such practices currently in these sectors. The research results indicate a significant correlation between the code of ethics and the attitude of professionals towards the unethical use of software in government and private sector organizations. These also indicate significant differences in government and private sectors.     

The effect of decision support system expertise on system use behavior and performance

We performed an empirical investigation into the effect of users’ decision support system (DSS) expertise on their problem-solving strategies. The results indicated that individuals who had only recently learned to use the DSS were confused or restricted by the set of functions provided by the system and did not plan well for their use of the DSS. Those who had previous knowledge of the system exhibited more focused and efficient problem-solving behavior. Our findings suggested that problem-solving strategies depended significantly on the user's level of system expertise.     

Exploring the impact of use context on mobile hedonic services adoption: An empirical study on mobile gaming in China

Unlike traditional technologies, the use of mobile technology is exposed to shifting use contexts. Use context has frequently been described as an important factor influencing the adoption of mobile innovations. However, empirical evidence about the impact of use context is limited. This paper investigated the effect of use context on the formation of users’ perceptions of mobile hedonic services by using mobile gaming as an example. Through the employment of structural equation modelling technology, an adoption model of mobile gaming is proposed and assessed based on results from 267 questionnaires. The results show that use context is the strongest predictor of mobile game adoption. It directly or indirectly affects all different perceptions of mobile gaming in significant ways, including perceived ease of use, perceived usefulness, perceived enjoyment, cognitive concentration, attitude and behavioral intention. Additionally, perceived usefulness, perceived enjoyment and cognitive concentration all have a positive influence on the attitudinal variables of mobile game acceptance. We concluded that the formation of people’s perceptions about mobile gaming is conditional and based on the special consideration of certain use contexts. Both theoretical and practical implications are discussed.     

Applying the integrative model of behavioral prediction and attitude functions in the context of social media use while viewing mediated sports

Based on the integrative model of behavioral prediction and attitude functions, the present investigation examines the motivations and factors that predict one’s intentions to use social media while viewing mediated sports. Structural equation modeling analysis revealed that the utilitarian functions, the social identity function, the self-esteem maintenance function, and self-efficacy positively predicted attitudes toward social media use while viewing mediated sports. Controlling for other possible behaviors, attitudes, norms, and self-efficacy predicted intentions to use social media. Results demonstrated that the integrative model, coupled with attitude functions, can explain a large amount of variance in one’s attitudes and media choice tendency.     

Determinants of choice of semantic web based Software as a Service: An integrative framework in the context of e-procurement and ERP

The ever increasing Internet bandwidth and the fast changing needs of businesses for effectiveness with the partners in the procurement chain and is leading organizations to adopt information systems infrastructures that are cost effective as well as flexible. The question seems to be: what is driving organizations to go in for Software as a Service (SaaS) based e-procurement and ERP, rather than the packaged model of software provisioning? Whereas there have been studies reporting technology, cost, quality, network externalities and process as the main variables in the utility function of the user, but most of the studies have modelled either one or two in the their models. The study is exploratory in nature and tries to identify, classify and rank dimensions affecting SaaS sourcing decisions. In this study, we developed an integrative framework to identify the determinants of choice of SaaS in the specific context of SaaS based e-procurement and ERP. The framework was then analyzed using the extended Analytic Hierarchy Process (AHP) method suggested by Liberatore (1987) and the relative importance and the weights of the criteria identified using data collected on 8 users and 9 service providers of SaaS based e-procurement and ERP. Although the analysis helped in identifying quality and costs as the two most important determinants of choice of SaaS based e-procurement and ERP, but the other criteria such as network externality benefits, technology and process were also found to be significant determinants of choice.     

The role of IT human capability in the knowledge transfer process in IT outsourcing context

Our research attempted to identify the behavioral process of knowledge transfer by examining the effects of IT human capability, human character, trust, and cooperative learning on it in an IT outsourcing situation. By analysing data collected from vendor and client matched-pair samples of 87 IT outsourcing projects, we found that both the client's and the vendor's character influenced trust, trust affects on cooperative learning, and the cooperative learning influence on knowledge transfer. More importantly, it we found that the client's IT human capability had a direct impact on cooperative learning and knowledge transfer. This indicated that client's IT human capability was a crucial factor in effective knowledge transfer during IT outsourcing. It also implied that client firms should identify and retain some IT personnel who can apply vendors’ competencies in IT practice and respond effectively to any technological challenges.     

The role of information technology in achieving the organisation's strategic development goals: A case study

The role of IT in achieving the organisation's strategic development goals has been an area of constant debate. This paper describes the experiences of John Nicholls Builders Ltd, a Cornish building firm, in their attempt to achieve their strategic development goals through the adoption of IT. The implementation stage of the project involved setting a flexible programme and timescale from the start. The company adopted a bottom up approach whereby potential users were consulted and involved in the process. Also the support of top management staff was crucial for the successful transition to the new system. Although there was no single ready-made solution that could fit the organisations requirements, they were able to identify appropriate construction industry software packages and integrate them through development of an intranet and database system. Now, there is greater management control, all departments have greater access to information, enabling them to function more effectively and efficiently, and since projections are more accurate or now available, management can make long-term strategic plans. These improvements and developments to the business system have improved operational efficiency, turnover and profitability of the organisation.     

The importance of the CobiT framework IT processes for effective internal control over financial reporting in organizations: An international survey

This paper presents the results of an international survey of IT professionals exploring the relationships between CobiT's IT processes and financial reporting. Our respondents rated the importance of each of CobiT's 34 processes from the viewpoint of effective internal control over financial reporting. Results revealed five processes that were deemed specially critical. We also find interesting patterns of results as a function of respondents’ employment type and geographic location. This survey of IT professionals shed light on the relevance of a widely used IT governance framework—CobiT—from the perspective of organizations’ internal controls.     

Network optimization algorithms and scenarios in the context of automatic mapping

Many different algorithms can be used to optimize the design of spatial measurement networks. For the spatial interpolation of environmental variables in routine and emergency situations, computation time and interpolation accuracy are important criteria to evaluate and compare algorithms. In many practical situations networks are not designed from scratch but instead the objective is to modify an existing network. The goal then is to add new measuring stations optimally or to withdraw existing stations with as little damage done as possible. The objective of this work is to compare the performance of different optimization algorithms for both computation time and accuracy criteria. We describe four algorithms and apply these to three datasets. In all scenarios the mean universal kriging variance (MUKV) is taken as the interpolation accuracy measure. Results show that greedy algorithms that minimize the information entropy perform best, both in computing time and optimality criterion.
