Information Technology and Life Expectancy: A Country-Level Analysis

Do countries with higher IT spending have higher life expectancy? Recent policy debate on healthcare in the United States has focused on the role of IT in reducing costs and improving healthcare access and quality. An implicit assumption in this debate has been that greater infusion of IT into healthcare will lead to better health outcomes. We investigate the validity of this assumption by examining the extent to which higher IT expenditures at the country level are associated with higher life expectancy, a key measure of healthcare outcomes. Drawing on the information systems and supply chain management literature, we theorize three mechanisms to explain why IT may be associated with healthcare outcomes at the country level: information integration, workflow coordination, and collaborative planning. We then conduct an empirical analysis relating IT investments with life expectancy and find that higher IT investments at the country level are positively associated with higher life expectancy. We discuss implications of the findings for further research and policy

Antecedents and Impacts of E-Business Aligment Amongst Small and Medium-Sized Enterprises

E-business has great potentials for firms to extend their business efficiency. Nevertheless, due to various problems and constraints, the e-business deployment within SMEs sector has been reported as not effective. To ensure effective e-business deployment, necessary measures are needed to assess how firms align diverse ebusiness capabilities in support of their business operation. This study therefore aims to investigate the extent firms align diverse e-business capabilities across business processes (e-business alignment). Using a strategic fit perspective, this study has observed two major propositions. First, firms‟ ability to align e-business to support the most crucial business processes has potentially led to better realisation of ebusiness values. Secondly, certain managerial and environmental conditions have explained the differing characteristics of e-business alignment amongst firms. This study employs quantitative research approach using survey method to collect and collate evidences from 140 owner/managers of SMEs. Preliminary analysis has indicated e-business alignment/misalignment patterns across business functions. The cluster analysis further reveals three distinct profiles with different characteristics of e-business alignment. These profiles are labelled as 'highly fit', 'moderately fit' and 'low fit' based on their e-business fit characteristics. This result confirms the first proposition where highly aligned firms will report greater and wider e-business impacts. The second proposition reveals that environmental uncertainty, IT sophistication, owner/manager knowledge on advanced IT/IS, e-business deployment status, and support network are significant predictors to different e-business alignment characteristics among firms. This study suggests that firms relatively have different priority over e-business solutions to support their business. These findings have demonstrated why some firms do not progress to a higher e-business ladder. It further justifies unequal deployment of e-business solutions to support functions across firms

Factors affecting the development of sophisticated database marketing systems.

In the late 1980s, companies in a wide variety of industries began to implement segmented marketing strategies using database marketing (DBM) systems. Several surveys noted that some organisations were developing sophisticated DBM systems to achieve competitive advantage, while others, in similar marketplaces, seemed unable, or unwilling, to exploit the potential benefits of these powerful systems. Alternatively, evidence from industrial reports suggested that most companies were failing to fully exploit the capabilities oftheir systems. Hence, this research was designed to determine the factors affecting levels of sophistication in database marketing (DBM) systems. First, theories from marketing and information systems were synthesised to develop a generic model of DBM systems. Next, notions about the sources of competitive advantage were reviewed to identify potential factors promoting the development of sophisticated DBM systems. This review resulted in four such factors being hypothesised: market orientation as a specific organisation culture, database size (i.e. number of customers) as a key resource, locus of control of the senior marketing manager as an important individual characteristic, and the difference between consumer and business markets as a factor in firms' external environment. Empirical data were collected from two random samples of senior marketing managers in US catalogue companies using postal surveys. Data from the first sample (36 observations) were used to develop a valid and reliable construct to measure the level of sophistication in DBM systems. Further data were collected from a second random sample using two further postal surveys (69 observations), which confirmed and replicated the results obtained from the first sample. Overall, the research findings show that the development of sophisticated DBM systems is positively associated with two factors: market orientation of organisation culture, and database size. The other two factors - locus of control and type of market - failed to show any association with the level of sophistication in DBM systems. Further data analyses revealed a strong association between the elements of sophisticated OBM systems and marketing notions of sources of competitive advantage

Information systems in organisations

This research explores two separate but related lines of enquiry - the business value of individual applications and the social and organisational impact of information systems. From this research it is clear that information systems have immense potential to change organisations. The conventional view focuses on the value that organisations can obtain through greater efficiency or new activities made possible by specific applications. But experience suggests that many organisations fail to gain the value expected. This research was started with the aim of attaining a greater understanding of the business value that information systems could offer organisations and finding ways by which organisations could assess and realise this value. The research has adopted a variety of methodological approaches and this integrating paper assesses the choices made and locates the papersin relation to the literature on information systems research methodology. The nine research papers taken together demonstrate that is business value is a complex concept and difficult to measure in practice. The research finds that the business and organisational environments are key factors in achieving the business value to be reaped from the range of benefits that each type of IS application offers. The research also demonstrates why IS evaluation practice continues to pose problems for researchers and practitioners. This integrating paper situates the work within the relevant literature on information systems research, assesses the contribution of the research papers to information systems research and concludes with a discussion of future research that flows from this work

A critical study of information system strategy formulation in a public sector context.

This thesis comprises a critical examination of Information System Strategy (ISS) formation in a public sector context, namely the Police Service in Scotland. Despite the apparent importance attached to ISS, and the proliferation of many methods to assist those engaged in ISS formation, the practice of ISS formation remains comparatively ill-understood.The concepts of strategy and power can be viewed as being closely linked. Using theory based accounts of power, we put forward a multi-dimensional conceptualisation of power as an aid to organisational analysis of ISS formation. Consequently, the focus of this work is not only a detailed investigation into ISS formation practice, but also one in which we evaluate the way in which a multi-dimensional conceptualisation of power affects our understanding of ISS formation practice. This research is based upon six longitudinal case studies of ISS formation in the Police Service. Data collection involved a number of methods: in-depth semi-structured interviews, informal conversation, participation, collection of documentation produced within the case study settings, and collation and analysis of documentary materials from secondary sources. The abstraction of several themes from a cross-case comparative analysis of issues has led to the development of a conceptual framework which underpins our contribution to knowledge: namely, a means of understanding ISS formation as micro-political activity, based upon an ongoing process of construction and reconstruction of social reality. This in turn can be considered as being based upon individual mental constructs, which in turn are influenced by the themes identified. Our framework has been developed as an epistemological device to aid thinking about ISS formation, rather than as a representation of what an ISS formation process is. Implicit in the framework is the contention that ISS formation reflects power relations; however, the practical difficulties in researching power issues should not be underestimated. Several areas for further research arising from this thesis are discussed
