Extending feature usage: a study of the post-adoption of electronic medical records

Technology Acceptance Model (TAM) posits that Perceived Ease of Use (PEOU) and Perceived Usefulness (PU) influence the ‘intention to use’. The Post-Acceptance Model (PAM) posits that continued use is influenced by prior experience. In order to study the factors that influence how professionals use complex systems, we create a tentative research model that builds on PAM and TAM. Specifically we include PEOU and the construct ‘Professional Association Guidance’. We postulate that feature usage is enhanced when professional associations influence PU by highlighting additional benefits. We explore the theory in the context of post-adoption use of Electronic Medical Records (EMRs) by primary care physicians in Ontario. The methodology can be extended to other professional environments and we suggest directions for future research.

Theoretical perspectives of enterprise architecture

The number of published Enterprise Architecture (EA) research has increased during the last few years. As a discipline, EA is still young and lacking theoretical foundation. Lately some research trying to ground EA to theory has been published, including linkage to systems theory. Enterprise Architecture can be defined as; (i) a formal description of the current and future state(s) of an organisation, and (ii) a managed change between these states to meet organisation’s stakeholders’ goals and to create value to the organisation. Based on this definition, this conceptual paper tries to shed light to theoretical underpinnings of EA from three theoretical perspectives; EA as a communication media, EA as an activity, and EA as an information technology system. Our conclusions are that; (i) EA can be categorised as a communication media and theoretically underpinned by ontology and semiotics, (ii) EA can be explained and theoretically underpinned by Activity Theory, and (iii) EA can be categorised as an information technology system and theoretically underpinned by General Systems Theory and Technology Acceptance Theory.

Workaround motivation model (WAMM): an adaptation of the Theory of Interpersonal Behaviour

The study of workarounds (WA) has increased in importance due to their impact on patient safety and efficiency. However, there are no adequate theories to explain the motivation to create and use a workaround in a healthcare sitting. Although theories of technology acceptance help to understand the reasons to accept or reject technology, they fail to explain drivers for alternatives. Also workarounds involve creators and performers that have different motivations. Models such as Theory of Planned Behaviour (TPB) or Theory of Reasoned Action (TRA) can help to explain the role of workaround users, but lack explanation of workaround creators’ dynamics. Our aim is to develop a theoretical foundation to explain workaround motivation behaviour models with norms that relate to sanctions to provide an integrated Workaround Motivation Model; WAMM. The development of WAMM model is explained in this paper based on workaround cases as part of further research to establish the model.

Evaluating e-learning systems: an empirical investigation on students' perception in higher education area

In search of better, traditional learning universities have expanded their ways to deliver knowledge and integrate cost effective e-learning systems. Universities’ use of information and communication technologies has grown tremendously over the last decade. To ensure efficient use of the e-learning system, the Arab Open University (AOU) in Bahrain was the first to use e-learning system there, aimed to evaluate the good and bad practices, detect errors and determine areas for further improvements in usage. This study critically evaluated the students’ perception of the elearning system in Bahrain and recommended changes to improve students’ e-learning usage. Results of the study indicated that, in general, students have favourable perceptions toward using the e-learning system. This study has shown that technology acceptance is the most variable, factor that contributes to students’ perception and satisfaction of the e-learning system.

MLCMS actual use, perceived use, and experiences of use

Mobile learning involves use of mobile devices to participate in learning activities. Most elearning activities are available to participants through learning systems such as learning content management systems (LCMS). Due to certain challenges, LCMS are not equally accessible on all mobile devices. This study investigates actual use, perceived usefulness and user experiences of LCMS use on mobile phones at Makerere University in Uganda. The study identifies challenges pertaining to use and discusses how to improve LCMS use on mobile phones. Such solutions are a cornerstone in enabling and improving mobile learning. Data was collected by means of focus group discussions, an online survey designed based on the Technology Acceptance Model (TAM), and LCMS log files of user activities. Data was collected from two courses where Moodle was used as a learning platform. The results indicate positive attitudes towards use of LCMS on phones but also huge challenges whichare content related and technical in nature.

E-learning opens the door to the global community. Novice users experiences of e-learning in a Somali University

E-learning has become one of the primary ways of delivering education around the globe. In Somalia, which is a country torn within and from the global community by a prolonged civil war, University of Hargeisa has in collaboration with Dalarna University in Sweden adopted, for the first time, e-learning. This study explores barriers and facilitators to e-learning usage, experienced by students in Somalia’s higher education, using the University of Hargeisa as case study. Interviews were conducted with students to explore how University of Hargeisa’s novice users perceived elearning, and what factors positively and negatively affected their e-learning experiences. The Unified Theory of Acceptance and Use of Technology (UTAUT) model was used as a framework for interpreting the results. The findings show that, in general, the students have a very positive attitude towards e-learning, and they perceived that e-learning enhanced their educational experience. The communication aspect was found to be especially important for Somali students, as it facilitated a feeling of belonging to the global community of students and scholars and alleviated the war-torn country’s isolation. However, some socio-cultural aspects of students’ communities negatively affected their e-learning experience. This study ends with recommendations based on the empirical findings to promote the use and enhance the experience of e-learning in post conflict Somali educational institutions

Mobile banking : concept and potential

The internet and the mobile phone - two technological advancements that have profoundly affected human behaviour in the last decade - have started to converge. The products .of this association are mobile data services. Using a variety of platforms, services are being created to enable mobile devices to perform many activities of the traditional internet, albeit in a reduced format for mobile devices. One area of activity is mobile (m-) banking (one of the first areas of commercial transaction on the wireless internet). Banking is an area that has extended in many different ways in recent years, including telephone and online banking. M-banking provides yet another channel for banking services, and in emerging markets, provides some possibility for becoming a primary channel. This paper examines the strategic implications of m-banking and the strategic positioning of m-banking services in different markets. The paper concludes with a discussion of the future for m-banking services.

A novel romance : conceptualising emotional attachment as a barrier to adoption

The Technology Acceptance Model (TAM) aims to understand consumers’ adoption of new technologies. Some 30 years after TAM was first proposed, it is still widely used today. This paper proposes an extended version of the TAM, with the primary addition to it being the construct of consumers’ emotional attachment to an existing product. The expanded TAM, Technology Acceptance Model with Emotional Attachment (TAME), is applied to the understudied area of e-book reader technology and its adoption by consumers who read for pleasure versus for academic purposes, as has been the focus of past research on e-book readers. The extended model considers consumers’ emotional attachment to paper books (pbooks) as a likely barrier to the take up of e-book reader technology.

Emotional connections to books and technological innovations : an e-book perspective

E-book devices are a technological innovation that has been mass marketed to consumers as a revolution in the way that books will be read and stored. This paper extends previous research on technology adoption behaviour of individuals by focusing on the role of emotional connections people have towards e-books. A number of technology adoption models can explain the adoption of e-book devices such as the technology acceptance model, theory of planned action, theory of reasoned action and social cognitive theory. Due to the increased importance of social learning on a person’s behaviour, social cognitive theory is identified in this paper as being the most appropriate theoretical lens to understand the emotional connections a person has towards e-books. The findings from this paper may help to fill the gaps in academic discussion about what theory best explains a person’s behavioural intention towards technological innovations and the impact of marketing on this behaviour. In addition, the paper has a number of managerial implications including identifying the importance of an emotional connection to a technological innovation that influences the adoption process. The emphasis on emotional connection as mediating the way a person receives information about e-book devices may help to influence future marketing efforts of new technologies.

Motivation-based IS evaluation strategy : a perspective of marketing information systems

The article describes the importance of motivational factors through an analysis of the core TAM constructs in the context of marketing IS evaluation. We argue that our findings compliment current IS evaluation strategy, specially for measuring motivational elements for online IS. The study consequently provides an empirical validation of the importance of motivational and behavioural factors. Through an experimental analysis we evaluated the relative importance of perceived enjoyment with perceived usefulness of using an online website for shopping purposes and found that enjoyment was by far the dominant predictor of attitude towards online shopping. The result illustrates that in terms of IS evaluation online environments have moved from being functional online applications to being functional, engaging and interactive online IS (e.g. websites).

Fatores determinantes de sucesso na adoção de softwares livres em empresas privadas: algumas evidências empíricas

Nowadays, the free software has been presented as an alternative to the acquisition structure of proprietors¿ software licenses, being adopted by a large number of companies. This study presents the analysis, through a case study, of a project of proprietors¿ software migration for free platforms. The main purpose was to identify decisive factors of success in the adoption of free softwares for private companies. For this, was used the single case methodology of study, presented by Yin (2005). The theoretical referential approaches issues related to the definitions and the historic of the free software, the resistance to information systems and the change resistance. The idea is to look for the fundamentals to support the researchers understanding of the situations observed in the field. The data found at this research was analyzed using a meta-frame, which has as the main point the Unified Theory of Acceptance and Use of Information Technology, developed by Venkatesh et al. (2003). Also, to complete this meta-frame, were used the Technology Acceptance Model, proposed by Davis (1989), and Interaction¿s Model of system and context of Use, developed by Markus (1983). The researche¿s result has been gotten by the analysis of documentation, interviews, questionnaires, direct observation and participant observation, that made possible the obtaining of valuable group of data on the researched subject. The result of this research allow the establishment of subsidies for the planning and development of project of proprietors¿ softwares migration for free softwares.

Fatores-chave na qualidade de sistemas de home broker : uma análise teórico-empírica

This work has as main objective the development of a key factors¿ model for the quality of Home Broker systems. An explanatory research was performed, based on a quantitative approach. To achieve this goal, some theoretical models of technology acceptance (TAM, TRA, TPB and IDT), reliability and quality of service were reviewed. It was proposed an extended key factors¿ model and developed a questionnaire, which was the research instrument used in this study. The questionnaire was applied over the Internet, from which was obtained a participation of 113 valid respondents, all of them users of Home Broker system. Once performed the data collection, statistical tests were used for the Factorial Analysis in order to achieve a definitive model. The key factors found were Perceived Usefulness, Perceived Ease of Use, Subjective Norms, Compatibility, Reliability and Relative Advantage. Some hypotheses from the model were also tested to investigate the relationship between the importance given to the factors and the resulting degree of satisfaction about quality of service. As a result of the study, a key factors¿ model for the quality of Home Broker systems was established, and identified that the factor Compatibility" has more explanatory power than the others."
