The use of a nursing informatics system as an exemplar to investigate business value of IT in healthcare

Researchers and decision makers in healthcare are taking great interest in clinical practices where there is a high potential to improve healthcare outcomes and reduce costs by incorporating a myriad of technology solutions. However, to date very few, if any of these IS/IT (information systems/information technology) solutions have realised the expected improvements to quality care with the expected cost reductions. This makes the need to evaluate the impact of IT on overall performance of clinical practices i.e. business value of IT a key strategic imperative in healthcare. To address this key need, we propose a comprehensive framework that conceptualises business value of IT in healthcare in different layers. To illustrate the proposed framework, a case study is used, which serves to examine the proposed conceptual model. The exemplar case study is an Australian-made nursing documentation system; an enterprise system that caters for multiple clinical users in acute healthcare contexts and hence provides appropriate richness to validate the proposed model.

The role of IT governance in generating business value from IT investments in healthcare: lessons from an Australian experience

Digitizing the core processes of healthcare delivery is looked at as a solution to control the escalating costs without compromising quality or patient outcomes. However, to date the business value of such IT solutions remains elusive, especially in view of the high failure rate of many solutions coupled with the high user resistance. The uniqueness of the healthcare industry makes measuring the business value of IT a complex missions, yet it is the thesis of this research that such an activity is an essential first step if we are to realise the full potential of IT in healthcare. The role IT governance can play is of high importance to generate business value from IT investments in healthcare. This is investigated using an integrative model that is proffered to conceptualise the business value of IT in healthcare. This conceptual model is then used to guide an exploratory case study based at a leading private healthcare provider in Melbourne-Australia.

A brief review of recent research trends on applications of computational and statistical techniques in financial and business intelligence

Artificial neural networks and statistical techniques like decision trees, discriminant analysis, logistic regression and survival analysis play a crucial role in Business Intelligence. These predictive analytical tools exploit patterns found in historical data to make predictions about future events. In this paper we have shown some recent developments of a few of these techniques in financial and business intelligence applications like fraud detection, bankruptcy prediction and credit rating scoring.

Towards a better understanding of how effective IT governance leads to business value : a literature review and future research directions

This paper reviews the existing literature on IT governance to assess whether IT governance has contributed to delivering business value from IT and if so, how. The conducted literature review has shown the scarce number of studies that focus on why and how effective IT governance may lead to business value. By using a structured literature review analysis, the paper has offered a number of insights to the topic of IT governance: a) provided a systematic definition of effective IT governance based on a multi-dimensional framework, b) listed benefits of effective IT governance, and c) identified mechanisms that lead effective IT governance to those benefits. This paper takes a step towards addressing the ‘why’ and ‘how’ knowledge gaps by synthesising the fragmented knowledge to provide the best that is known about the subject and to identify future research directions.

Tracking and tracing applications of 3G for SMEs

With dynamic growth and acceptance of mobile devices, many innovative business applications are beginning to emerge. Tracking and tracing seems to be one of the popular applications which many organisations have initiated, often facilitated by location based services provided by mobile network operators. However, there are many issues associated with the provisioning of this application with current technologies and business models. Small and Medium-size Enterprises (SMEs) that make up a significant segment of businesses worldwide do not yet seem able to benefit widely from these services. In this chapter, we initially review current technologies/ applications and the issues associated with them, drawing from research and the experiences of a long term ongoing action research project with SMEs in the trade sector. Subsequently, we explore the opportunities offered by 3G services/business applications to SMEs, and provide a broad critical outlook on future opportunities for SMEs to benefit from 3G services.

Some unusual applications of the `Error-bar` feature in Excel spreadsheets

This paper demonstrates how the "error-bar" feature can be used to extend the utility of "worldware" spreadsheet packages in producing high-quality graphs for university teaching and learning, and for research. To further utilize the advantages of spreadsheets in university education, this paper seeks to overcome some of the earlier reservations about the lack of scientific plotting capabilities of spreadsheet applications. Specific examples of educational material in the areas of enzyme kinetics, vibrational spectroscopy, vibronic spectroscopy, and mass spectrometry are discussed. It is argued that, where practical, university educators should use "worldware" packages to prepare teaching aids, since these would better prepare their students for future employment. The use of software features for purposes that were not envisioned by the programmers has additional educational benefits in fostering flexibility and innovation. Other graphing packages can also use the "error-bar" feature in a manner similar to that described here for Excel.

The Strategic outsourcing Decision of IT and eCommerce: The Case of Small Businesses in New Zealand

In New Zealand, small to medium-sized enterprises (SMEs) play a very important role in the economy by their contribution to both employment and gross domestic product. Addressing issues pertinent to SMEs is of paramount importance in driving this sector forward. Information Technology (IT) emerges as one main enabler for SMEs in automating their operations, seeking new opportunities and enhancing their strategic business positioning in local and international markets. However, the inability of SMEs to handle the dynamic nature of IT due to problems inherent in their size, structure and resources, makes it difficult for them to take appropriate decisions to benefit from the IT technologies. The advent of eCommerce (EC) has only compounded this problem. One way out of this complex situation is to outsource the IT and EC technology requirements by the SMEs. This study endeavours to identify the pattern of IT and EC outsourcing issues of SMEs within New Zealand. This research attempts to identify the main driver for IT/EC outsourcing in SMEs as well as to explore the problems of IT outsourcing and makes suggestions for further research in this crucial sector.

Small business peceptions of online marketing research

Concerns over the overall cost of marketing research and the cost per usable response have in large measure caused marketing practitioners to turn to online marketing research techniques, either as a solus technique, or in a mixed mode application. However, the use of e-mail and mixed mode surveys such as postal invitations to complete online questionnaires present both familiar and new issues, as the extant literature illustrates. This paper examines an earlier study before reporting findings from the present study, which employs a method that ascertains the probability of commissioning and/or responding to four survey research methods, described in scenarios and delivered using e-mail and the World Wide Web (Web). It is evident that while perceptions of e-mail, the Internet, and privacy have changed since early use of the Internet and more particularly the World Wide Web, and there is acknowledgment in the literature concerning the lower costs and faster response speeds of online marketing research, small businesses do appear to discriminate in favour of targeted online survey methods over postal surveys, portrayed as scenarios in this study. They indicate a greater likelihood of responding to targeted, hybrid email/Web surveys than traditional postal surveys.

Applications of cognitive theories to children's fire safety education

Children under five have the highest rate of fire-related accidents (Australian Institute of Health and Welfare, 2001). It is therefore essential to develop effective fire safety education programs to prevent casualties due to a fire. At present, there are fire education programs conducted across Australia for primary school children. However, it is vital that these programs get their message across to the children in the most efficient manner to help children retain the information. The present study evaluated the effectiveness of the 'Fire Ed' program conducted in Victoria and assessed the retention of fire safety information in children in preparatory and Grade five levels. The findings suggest that the information is not retained over long periods of time. Suggestions are made to provide fire safety education in line with
theories of cognitive development to make it more effective.

Gender issues in the career development of IT professionals: a global perspective

Each period of technological change carries with it high expectations of societal and organizational restructuring that will favour the disadvantaged. The same is true for the Information and Communication Technologies. The fast expansion of the IT labour market, the need for diverse talents, the shift in the demand from technical to more general management and business skills, and the government's and employer's initiatives to improve women's representation in the IT sector created an image that? IT is one of the best-equal opportunity areas 'that provide wider opportunities for women to enter and succeed in this industry'. Nevertheless, the validity of these claims is yet to be established through empirical analysis.

An overview of IT outsourcing in public secto agenices

For the past 15 years, governments in the developed, Western world have been contracting out, or outsourcing, services as a key part of public sector reforms. Outsourcing has been argued to lead to cost savings, improved discipline, better services, access to scarce skills, and the capacity for managers to focus more time on the core business of their organizations (Domberger, 1998). Government outsourcing initiatives have encompassed a range of services, but given the large sums of money invested in IT assets, the outsourcing of IT services (IT outsourcing, or ITO) has been a major initiative for many agencies. Lacity and Willcocks (1998, p. 3) defined ITO as "handing over to a third party [the] management of IS/IT assets, resources and/or activities for required results." For public-sector outsourcing, this handover is usually made by way of a competitive tender. Case studies have reported ITO successes and failures (e.g., Currie & Willcocks, 1998; Rouse & Corbitt, 2003; Willcocks & Currie, 1997; Willcocks & Lacity, 2001; Willcocks & Kern, 1998), but much of the evidence presented to public-sector decision makers to justify this reform is anecdotal and unsystematic, and when investigated in depth, does not necessarily support widespread conclusions.

A longitudinal study of the commitment to business ethics of corporate Australia

This paper compares the results of a longitudinal study of ten years, conducted at five yearly intervals, from 1995 to 2005. The aim of the study was to examine the commitment to business ethics of the top 500 Australian companies. Primary data was obtained via a self-administered mail questionnaire distributed to a census of the top 500 Australian companies. This paper examines those responses that indicated that their company possessed a code of ethics. The paper finds that business ethics has continued to evolve and that, in most cases, such evolution has been positive. It would seem that codes of ethics have moved beyond a regulatory requirement and are now considered an integral component of corporate culture and commercial practice in many of Australia's top companies.

Chemistry, spectroscopy and analytical applications of certain chemiluminescent reactions

Chemiluminescence, the production of light from a chemical reaction, has found widespread use in analytical chemistry. Both tris (2, 2’-bipyridyl) ruthenium (II) and acidic potassium permanganate are chemiluminescence reagents that have been employed for the determination of a diverse range of analytes. This thesis encompasses some fundamental investigations into the chemistry and spectroscopy of these chemiluminescence reactions as well as extending the scope of their analytical applications. Specifically, a simple and robust capillary electrophoresis chemiluminescence detection system for the determination of codeine, O6-methylcodeine and thebaine is described, based upon the reaction of these analytes with chemically generated tris(2,2'-bipyridyl)ruthenium(III) prepared in sulfuric acid (0.05 M). The reagent solution was contained in a glass detection cell, which also held both the capillary and the cathode. The resultant chemiluminescence was monitored directly using a photomultiplier tube mounted flush against the base of the detection cell. The methodology, which incorporated a field amplification sample introduction procedure, realised detection limits (3a baseline noise) of 5 x 10~8 M for both codeine and O6-methylcodeine and 1 x 10~7 M for thebaine. The relative standard deviations of the migration times and the peak areas for the three analytes ranged from 2.2 % up to 2.5 % and 1.9 % up to 4.6 % respectively. Following minor instrumental modifications, morphine, oripavine and pseudomorphine were determined based upon their reaction with acidic potassium permanganate in the presence of sodium polyphosphate. To ensure no migration of the permanganate anion occurred, the anode was placed at the detector end whilst the electroosmotic flow was reversed by the addition of hexadimethrine bromide (0.001% m/v) to the electrolyte. The three analytes were separated counter to the electroosmotic flow via their interaction with a-cyclodextrin. The methodology realised detection limits (3 x S/N) of 2.5 x 10~7 M for both morphine and oripavine and 5 x 10~7 M for pseudomorphine. The relative standard deviations of the migration times and the peak heights for the three analytes ranged from 0.6 % up to 0.8 % and 1.5% up to 2.1 % respectively. Further improvements were made by incorporating a co-axial sheath flow detection cell. The methodology was validated by comparing the results realised using this technique with those obtained by high performance liquid chromatography (HPLC), for the determination of both morphine and oripavine in seven industrial process liquors. A complimentary capillary electrophoresis procedure with UV-absorption detection was also developed and applied to the determination of morphine, codeine, oripavine and thebaine in nine process liquors. The results were compared with those achieved using a standard HPLC method. Although over eighty papers have appeared in the literature on the analytical applications of acidic potassium permanganate chemiluminescence, little effort has been directed towards identifying the origin of the luminescence. It was found that chemiluminescence was generated during the manganese(III), manganese(IV) and manganese(VII) oxidations of sodium borohydride, sodium dithionite, sodium sulfite and hydrazine sulfate in acidic aqueous solution. From the corrected chemiluminescence spectra, the wavelengths of maximum emission were 689 ± 5 nm and 734 ± 5 nm when the reactions were performed in sodium hexametaphosphate and sodium dihydrogenorthophosphate or orthophosphoric acid environments respectively. The corrected phosphorescence spectrum of manganese(II) sulfate in a solution of sodium hexametaphosphate at 77 K, exhibited two peaks with maxima at 688 nm and 730 nm. The chemical and spectroscopic evidence presented strongly supported the postulation that the emission was an example of solution phase chemically induced phosphorescence of manganese(II). Thereby confirming earlier predictions that the chemiluminescence from acidic potassium permanganate reactions originated from an excited manganese(II) species. Additionally, these findings have had direct analytical application in that manganese(IV) was evaluated as a new reagent for chemiluminescence detection. The oxidations of twenty five organic and inorganic species, with solublised manganese(IV), were found to elicit analytically useful chemiluminescence with detection limits (3 x S/N) for Mn(II), Fe(II), morphine and codeine of 5 x 10-8 M, 2.5 x 10-7 M, 7.5 x 10-8 M and 5 x 10-8M, respectively. The corrected emission spectra from four different analytes gave wavelengths of maximum emission in the range from 733 nm up to 740 nm indicating that these chemiluminescence reactions also shared a common emitting species, excited manganese(II). Whilst several analytical problems were addressed in this thesis and answers to certain questions regarding the fundamentals of acidic potassium permanganate chemiluminescence were proposed, there are several areas that would benefit from further research. These are outlined in the final chapter of this thesis.
