What drives the end user to build a feral information system?

A Feral Information Systems (FIS) is any technological artefact (e.g. spreadsheets) that end users employ instead of the mandated Enterprise System (ES). ES proponents suggest that the installation of an ES will boost productivity. However, Production Possibility Frontier theory provides insights as to why the introduction of an ES may instead suppress an end user's productivity. Structuration Theory offers insights that explain how certain end users may have access to powerful resources. Rather than submitting to the ES, the end user can employ FIS to block or circumvent aspects of the ES. Further, the concept of life chances helps explain why individuals may or may not develop the core skills required to construct an alternate to the ES, the FIS. In relation to the ES usage, an end user may adopt one of four Modes of Operation, namely: Submit, Dismiss, Hidden, or Defiant.

Predicting the acceptance of unit guide information systems

Information Systems can play an important role in ensuring and improving the quality of education provided. However, lack of acceptance of these information systems and resistance of technology innovations by the end users limit the expected benefits of the system. This research attempts to identify the key determinants for the acceptance of the Unit Guide Information Systems (UGIS) in the Australian higher education sector. The technology acceptance model (TAM), social cognitive theory (SCT) and model of PC utilization (MPCU) are combined to provide a new framework for this analysis. Results of the study are consistent with the technology acceptance factors for explaining the behavioural intention of the academics. The study also shows the effects of application specific self-efficacy, application specific anxiety and social influence on the acceptance of UGIS. Implications of the results are discussed within the context of unit guides and curriculum mapping.

Estimating non-response bias in a web-based survey of technology acceptance : a case study of unit guide information systems

Surveys are mostly challenged by response rates. Among the various types of survey research, web-based (internet-based/electronic/online) surveys are commonly used for data collection for a geographically diverse population. In surveys with high/low response rates, non-response bias can be a major concern. While it is not always possible to measure the actual bias due to non-response there are different approaches and techniques that help to identify reasons of non-response bias. The aims of this paper are twofold. (1) To provide an appropriate, interesting and important non-response bias case study for future web-based surveys that will provide guidance to other Information Systems researchers. The case-study concerns an online-survey to evaluate a technology acceptance model for Unit Guide Information systems (UGIS). (2) To discuss how nonresponse bias in a web-based technology acceptance study of an information system (UGIS in this case) can be contained and managed.

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).

The tale of two cultures : differences in technology acceptance in Twitter usage

Despite its huge uptake all over the world, Twitter is still in its early stages of being used as an educational tool. Here, we present an experiment that was conducted across two undergraduate groups from different universities, an Australian and another American university. In this experiment we looked at Twitter usage in class and compared the results with a particular focus on analysing technology acceptance differences between the two groups. Both groups used Twitter as part of their tutorial work and participated in a survey at the end of the semester. Empirical investigation was done using Davis’ technology acceptance model (TAM). The study findings reveal highly significant differences in the technology acceptance behaviours of the two groups, thus highlight cultural differences in the acceptance of technology, in this case Twitter.

Extending technology acceptance model to the E-recruitment context in Iran

Using a sample of 332 job applicants in Iran, this study integrates Technology Acceptance Model (TAM) and signaling theory to explain factors influencing applicants' behavioral intentions to apply for jobs online. Of the two main constructs of TAM, perceived usefulness was found to have a significant impact on applicants' behavioral intentions, while perceived ease of use was not. Based on the signaling theory, impression of the organizational website appeared to create interests in organization as a potential employer; hence, prompt applicants to apply for jobs. These results extend our understanding of the online recruitment in different context and provide further insights with regard to possible effects of website features on applicants' attractions toward organizations operating in Iran.

Improving Top-N recommendations with user consuming profiles

In this work, we observe that user consuming styles tend to change regularly following some profiles. Therefore, we propose a consuming profile model to capture the user consuming styles, then apply it to improve the Top-N recommendation. The basic idea is to model user consuming styles by constructing a representative subspace. Then, a set of candidate items can be estimated by measuring its reconstruction error from its projection on the representative subspace. The experiment results show that the proposed model can improve the accuracy of Top-N recommendations much better than the state-of-the-art algorithms.

Magával ragadó interfészek Art Education tanítás és tanulás vegyes valóság virtuális és valós környezetben

How selected next generation technologies support collaborative participation between higher education students and educators within a virtual socially networked e-learning landscape and encourage the interaction of communities of learners in multiple modes, ranging from text and images accessed within the Deakin Studies Online learning management system to a constructed virtual world in which the user’s creative imagination transports them to the “other side” of their computer screens is discussed in this paper. These constructed environments enable multiple simultaneous participants to access graphically built 3D environments, interact with digital artifacts and various functional tools and represent themselves through avatars, to communicate with other participants and engage in collaborative art learning.

Human performance measures for interactive haptic-audio-visual interfaces

Virtual reality and simulation are becoming increasingly important in modern society and it is essential to improve our understanding of system usability and efficacy from the users’ perspective. This paper introduces a novel evaluation method designed to assess human user capability when undertaking technical and procedural training using virtual training systems. The evaluation method falls under the user-centred design and evaluation paradigm and draws on theories of cognitive, skillbased and affective learning outcomes. The method focuses on user interaction with haptic-audio-visual interfaces and the complexities related to variability in users’ performance, and the adoption and acceptance of the technologies. A large scale user study focusing on object assembly training tasks involving selecting, rotating, releasing, inserting and manipulating 3D objects was performed. The study demonstrated the advantages of the method in obtaining valuable multimodal information for accurate and comprehensive evaluation of virtual training system efficacy. The study investigated how well users learn, perform, adapt to and perceive the virtual training. The results of the study revealed valuable aspects of the design and evaluation of virtual training systems contributing to an improved understanding of more usable virtual training systems.

Enhancement of user level controls in cloud databases

Industries in developed countries are moving quickly to ensure the rapid adoption of cloud computing. At this stage, several outstanding issues exist, particularly related to Service Level Agreements (SLAs), security and privacy. Consumers and businesses are willing to use cloud computing only if they can trust that their data will remain private and secure. Our review of research literature indicates the level of control that a user has on their data is directly correlated to the level of data privacy provided by the cloud service. We considered several privacy factors from the industry perspective, namely data loss, data storage location being unknown to the client, vendor lock-in, unauthorized secondary use of user's data for advertising, targeting secured backup and easy restoration. The level of user control in database models were identified according to the level of existence in these privacy factors. Finally, we focused on a novel logical model that might help to bring the level of user control of privacy in cloud databases into a higher level.

Telephone survey of service-user experiences of a telephone-based mental health triage service

The participation of service users in all aspects of mental health service delivery including policy development, service planning and evaluation is increasingly an expectation of contemporary mental health care. Although there are a growing number of publications reporting service-user perspectives in the evaluation of mental health services, little attention has been paid to the views of service users about mental health triage services. The purpose of the study reported here was to examine service-users' (consumers and informal carers) experiences of a telephone-based mental health triage service. Using a framework developed from the World Health Organisation's elements of responsiveness, we conducted structured telephone interviews with service users who had contacted a telephone-based mental health triage service in regional Victoria, Australia. The main findings of the study were that consumers experienced more difficulty than carers in accessing the service and that, although most participants were satisfied, only a minority reported being involved in decision-making. Further work is needed to improve accessibility of mental health triage services and to investigate barriers to consumer self-referral. Professional development and practice support systems should be established to support mental health triage nurses in the development of collaborative, consumer-focused care.
