A Welfare Analysis Of The Commonwealth Seniors Health Card, Peter M. Siminski
A Welfare Analysis Of The Commonwealth Seniors Health Card, Peter M. Siminski
Faculty of Commerce - Papers (Archive)
The Commonwealth Seniors Health Card (CSHC) is a key element of a suite of benefits for Australia's 'self-funded retirees'. Its main component is a pharmaceutical concession, which is analysed as a form of public health insurance. The utility gain through risk-pooling is found to be negligible under conservative assumptions. The deadweight loss through moral hazard may be considerable. Finally, the CSHC may be seen as an inequitable transfer, because CSHC holders are a particularly wealthy population.

Background Interpretation of comprehensive DNA microarray data sets is a challenging task for biologists and process engineers where scientific assistance of statistics and bioinformatics is essential. Interdisciplinary cooperation and concerted development of software-tools for simplified and accelerated data analysis and interpretation is the key to overcome the bottleneck in data-analysis workflows. This approach is exemplified by gcExplorer an interactive visualization toolbox based on cluster analysis. Clustering is an important tool in gene expression data analysis to find groups of co-expressed genes which can finally suggest functional pathways and interactions between genes. The visualization of gene clusters gives practitioners an understanding …
Exploratory And Inferential Analysis Of Gene Cluster Neighborhood Graphs, Theresa Scharl, Ingo Voglhuber, Friedrich Leisch

Background Many different cluster methods are frequently used in gene expression data analysis to find groups of co-expressed genes. However, cluster algorithms with the ability to visualize the resulting clusters are usually preferred. The visualization of gene clusters gives practitioners an understanding of the cluster structure of their data and makes it easier to interpret the cluster results. Results In this paper recent extensions of R package gcExplorer are presented. gcExplorer is an interactive visualization toolbox for the investigation of both the overall cluster structure and single clusters. The different visualization options including arbitrary node and panel functions are described …
The Use Of Computer Supported Analysis For Interview Data: A Cross-Cultural Example From The Electronic Gaming Industry, June Buchanan, Michael L. Jones
The Use Of Computer Supported Analysis For Interview Data: A Cross-Cultural Example From The Electronic Gaming Industry, June Buchanan, Michael L. Jones

Computer assisted analysis has long been a major factor of quantitative analysis. This paper illustrates the use of computer assisted analysis for qualitative research, looking specifically at research in the Electronic Gaming Industry, across two country sectors – New South Wales, Australia and Nevada, USA, where empirical data are collected and analysed. The paper highlights the important place that computer assisted analysis holds in social and societal marketing. A detailed discussion explains how analysis was undertaken in the Electronic Gaming Industry, and how concepts and theory emerged. This paper discusses the qualitative approach used in this research. In particular, it …
A Theoretical Analysis Of Bank Relationship, Shyam S. Bhati, Michael Mccrae, Anura De Zoysa
A Theoretical Analysis Of Bank Relationship, Shyam S. Bhati, Michael Mccrae, Anura De Zoysa

This paper analyses the banking relationship between branch manager and loan officer of a bank branch using two theoretical approaches - Agency Theory and Trust Theory. The analysis is performed across five dimensions of the business relationship between branch manager and loan officer – supervisor subordinate relationship, delegation of authority, assumption of risk in lending, goal congruence and mutual dependence. It is concluded that Trust theory is better descriptor of the banking relationship between branch manager and loan officer as compared to Agency theory because Trust theory can explain situations involving multifaceted relationship such as one between branch manager and …
Opportunities For Interactivity In Public Health Websites: A Content Analysis Approach, Sumayya Banna, Helen M. Hasan, Joseph A. Meloche
Opportunities For Interactivity In Public Health Websites: A Content Analysis Approach, Sumayya Banna, Helen M. Hasan, Joseph A. Meloche
Faculty of Commerce - Papers (Archive)
The Internet has many advantages over other media in the provision of information services in the area of public health. However many designers are not yet taking full advantage of its potential for interactivity. This paper examines the development of interactivity in public health websites in the increasingly important area of Palliative Care. Content analysis is used here to map the interactivity in a sample of 30 existing websites along with Heeter’s six dimensions (content and availability of choice, effort users must exert, responsiveness to the users, and the ease of adding information, monitoring the information and the system use, …
From Spider-Man To Hero - Archetypal Analysis In R, Manuel Eugster, Friedrich Leisch
From Spider-Man To Hero - Archetypal Analysis In R, Manuel Eugster, Friedrich Leisch
Faculty of Commerce - Papers (Archive)
Archetypal analysis has the aim to represent observations in a multivariate data set as convex combinations of extremal points. This approach was introduced by Cutler and Breiman (1994); they defined the concrete problem, laid out the theoretical foundations and presented an algorithm written in Fortran. In this paper we present the R package archetypes which is available on the Comprehensive R Archive Network. The package provides an implementation of the archetypal analysis algorithm within R and different exploratory tools to analyze the algorithm during its execution and its final result. The application of the package is demonstrated on two examples.

This paper uses empirical data on 161 listed manufacturing companies in Sri Lankaand Malaysia over the period of 2006 to 2008, and compares the performance of thesecompanies against two commonly used financial performance indicators: Return onAssets (ROA) and Return on Equity (ROE). The results indicate that during this periodSri Lankan manufacturing companies were considerably more profitable than theircounterparts in Malaysia in terms of ROA but less profitable in terms of ROE. It alsoidentifies a relatively weaker position of equity investments in the manufacturing sectorof Sri Lankan companies and attributes this to a number of factors, including: arelatively poor equity market, …
