Understanding Individual Experiences of Chronic Illness with Semantic Space Models of Electronic Discussions

Electronic discussion groups provide a convenient forum for individuals to share their experiences of chronic illness. The language use of individual participants, and the way their language shifts over time, may provide implicit indications of important shifts in sense-of-self. This paper relates experience with application of the hyperspace analogue to language (HAL) model for automatic construction of a dimensional model from a corpus of text. HAL is applied to 17 months of discussion on a closed list of 20 women coping with chronic illness. The discussion group was moderated for a focus the phenomenon of "Transition' - how people can learn to incorporate the consequences of illness into their lives. The current phase of research focuses on identification of clusters of words that can represent key aspects of Transition. The HAL models for two participants have been analyzed by experts in Transition to form candidate clusters. These clusters are then used as a basis for contrasting the language usage of an individual participant over time as compared to the entire corpus. We have not yet found a reliable basis for identifying transitions in an individual based on their entries into a discussion forum, although the clusters may have some inherent value for introspection on individual experiences and Transition in general. We report challenges for interpretation of the HAL model related to the correlation of dimensions and the impact of group dynamics

Exploration of location-based services adoption

As mobile technologies become more ubiquitous in the general population, it is reasonable to assume that individuals will consume services and software to enhance their aspirations and entertainment desires. This paper discusses a controlled experiment to explore aspects of user perceptions of their use of location-based services. This study examines a location-based service prototype experiment and analysis based on the UTAUT model. The results show significant indicators that suggest behavior patterns of early adopters of location-based services are being observed. We discuss these influences and attempt to explain their significance. Moreover, more curiously we discuss why some of our model was unsupported and postulate why

IT governance measurement tools and its application in IT-business alignment.

The purpose of this exploratory research paper is to evaluate the deployment and assessment methodology of the information technology governance (ITG) measurement tools, with the purpose of gaining deeper insight into the ITG initiation process, the nature of tools employed, measurement processes, and the implementation methodology, using case studies. Analysis of the available academic and non-academic literature sources showed measurement issues being the most dominant and ironically the most neglected domain in ITG implementations. We view ITG measurement tools and it subsequent deployment through the two theoretical ITG models namely the Integrated IT Governance model, and the Structures, Processes, and Relational ITG model. To validate these findings and to get a deeper insight into the ITG measurement domain, we conducted four case studies of measurement tools usage and processes in commonly used ITG frameworks in four organisations in New Zealand and United Arab Emirates. The results indicate that the IT governance initiatives differ in the manner of positioning in the integrated ITG framework, and objectivity of measurement is more evident and emphasized in UAE than in New Zealand. The result of these findings provides practitioners with guidance on the contextual usage of ITG measurement practices

A Study on the Effects of Product Types and Culture on the Level of Use of BIN Auctions by Sellers

Unlike most previous studies on Buy-It-Now (BIN) auctions, this study investigates factors that affect the level of use of BIN auctions by sellers. This study proposes a conceptual model in which product types and culture are two important factors affecting sellers’ decisions on the level of use of BIN auctions. The empirical investigation exhibits that sellers of homogeneous products are more likely to use BIN auctions than sellers of heterogeneous and antique-like products do. The result also shows that the level of use of BIN auctions can be explained by the Hofstede’s Culture Dimensions. While power distance brings a positive impact, uncertainty avoidance and individualism bring negative impacts on the level of use of BIN auctions by sellers. The results provide valuable insights for sellers and Internet marketplace operators to refine their business strategies and their plans for expanding their businesses to overseas markets

Study of Relationship between Customer Focus and Organizational Performance in the Telecommunication Organizations of Pakistan

Quality culture and performance of the organizations has become matter of concentration and interest for the researchers and practitioners from last few decades. The purpose of this study was to explore the relationship between quality culture and organizational performance with mediating effect of competitive advantage and moderating effect of human resource. It has been observed that telecommunication companies of Pakistan are facing tough contest and no empirical research has been known to be conducted in Pakistan within the context of quality culture, organizational performance with a mediating effect of competitive advantage and a moderating effect of human resource. The literature review has exposed seven characteristics of quality culture like; employee involvement, senior management leadership, effect of CEO, supplier partnership, customer focus, teamwork, and open corporate culture. 500 questionnaires were circulated in telecommunication companies and 250 received back of which 207 were valid. To examine the validity and reliability of data collected, different statistical techniques and tools have been applied like; Cronbach’s alpha, factor analysis, Pearson correlation, and multiple regression. Results of these statistical techniques have revealed that there is positive and significant association between independent variable (quality culture) and dependent variable (organizational performance). Mediating variable (competitive advantage) also shown reliable connection but moderating variable (human resource) has not created optimistic results. Keywords: Quality culture, customer focus, organizational performance, competitive advantage

A theory-grounded framework of Open Source Software adoption in SMEs

This is a post-peer-review, pre-copyedit version of an article published in European Journal of Information Systems. The definitive publisher-authenticated version Macredie, RD and Mijinyawa, K (2011), "A theory-grounded framework of Open Source Software adoption in SMEs", European Journal of Informations Systems, 20(2), 237-250 is available online at: http://www.palgrave-journals.com/ejis/journal/v20/n2/abs/ejis201060a.html.The increasing popularity and use of Open Source Software (OSS) has led to significant interest from research communities and enterprise practitioners, notably in the small business sector where this type of software offers particular benefits given the financial and human capital constraints faced. However, there has been little focus on developing valid frameworks that enable critical evaluation and common understanding of factors influencing OSS adoption. This paper seeks to address this shortcoming by presenting a theory-grounded framework for exploring these factors and explaining their influence on OSS adoption, with the context of study being small- to medium-sized Information Technology (IT) businesses in the U.K. The framework has implications for this type of business – and, we will suggest, more widely – as a frame of reference for understanding, and as tool for evaluating benefits and challenges in, OSS adoption. It also offers researchers a structured way of investigating adoption issues and a base from which to develop models of OSS adoption. The study reported in this paper used the Decomposed Theory of Planned Behaviour (DTPB) as a basis for the research propositions, with the aim of: (i) developing a framework of empirical factors that influence OSS adoption; and (ii) appraising it through case study evaluation with 10 U.K. Small- to medium-sized enterprises in the IT sector. The demonstration of the capabilities of the framework suggests that it is able to provide a reliable explanation of the complex and subjective factors that influence attitudes, subjective norms and control over the use of OSS. The paper further argues that the DTPB proved useful in this research area and that it can provide a variety of situation-specific insights related to factors that influence the adoption of OSS

The Role of Gender in Students’ Decisions to Major in Information Systems

In order to understand the reasons for women’s underrepresentation in IS, we extended the IS Major Choice Goals Model, which identifies the major factors that influence students’ pursuit of IS majors and careers. There were significant differences between female and male students in terms of self-efficacy, interests, and choice goals. Significant gender differences were also found in the relationships among the key determinants of the model meaning that females and males differed with respect to how they developed aspirations to major in IS. The relationship between self-efficacy and interest was stronger in females than in males, as well as the relationship between self-efficacy and outcome expectations. Self-efficacy influenced choice goals more strongly for males than it influenced females. The relationship between outcome expectations and interest was stronger in males than in females. Interest influenced choice goals more strongly for female students than it influenced male students

A role allocation model for IT controls in a cloud environment.

The rapid adoption of cloud computing by organizations, along with the need to comply with relevant IT governance (ITG) controls, has increased the complexity of governance in the cloud. This transition from a classical data center to a virtualized data center has resulted in the reallocation of roles and responsibilities of IT personnel for managing and accounting for the relevant IT controls. With a lack of guidelines or model for practitioners to choose from, with regard to the allocation of roles and responsibilities, there is a lack of clarity on the responsibilities and accountability for these IT controls. The purpose of this paper is to propose a theoretical model for assigning roles and responsibilities for IT controls for an organization operating in a cloud environment. The proposed model is based on a strong theoretical grounding and can be used to inform good practice
