Mathematical Programming Approaches to the Three-Group Classification Problem

Description: In the last twelve years there has been considerable research interest in mathematical programming approaches to the statistical classification problem, primarily because they are not based on the assumptions of the parametric methods (Fisher's linear discriminant function, Smith's quadratic discriminant function) for optimality. This dissertation focuses on the development of mathematical programming models for the three-group classification problem and examines the computational efficiency an… more

The Organizational Consequences of Information Deployment

Description: This study investigates the influence that increasing end user autonomy has on organizational data models. The independence offered by microcomputer technology offers users increasing independence in their information-handling activities. As independence increases, uniformity of data models across the organization is theorized to diminish. The problem motivating this study is the potential for improper allocation of resources that may result from a misinterpretation of organizational data. This… more

Organizational Considerations for and Individual Perceptions of Web-Based Intranet Systems

Description: Utilization of World Wide Web style Web-Based Intranet Systems (W-BIS) is a rapidly expanding information delivery technique in many organizations. Published reports concerning these systems have cited return on investment values exceeding 1300% and direct payback time periods as low as six to twelve weeks. While these systems have been widely implemented, little theoretically grounded research has been conducted in relation to users' acceptance, utilization or the perceived quality of these sy… more

The Relationships of Cross-Cultural Differences to the Values of Information Systems Professionals within the Context of Systems Development

Description: Several studies have suggested that the effect of cultural differences among Information Systems (IS) professionals from different nations on the development and implementation of IS could be important. However, IS research has generally not considered culture when investigating the process of systems development. This study examined the relationship between the cultural backgrounds of IS designers and their process-related values with a field survey in Singapore, Taiwan, the United Kingdom and… more

The Risks and Effects of Outsourcing on the Information Systems Function and the Firm

Description: IS outsourcing, especially large-scale IS outsourcing, is a comparatively recent and rapidly growing IS phenomenon, but it is also an inherently risky activity. In an IS outsourcing arrangement, the outsourcing vendor accepts responsibility for IS resources and functions formerly controlled directly by the firm. This research examines IS outsourcing from two perspectives. (1) From an IS perspective, it examines the risk perceptions of IS managers of fourteen Fortune-500 firms who had recently c… more

Robustness of Parametric and Nonparametric Tests When Distances between Points Change on an Ordinal Measurement Scale

Description: The purpose of this research was to evaluate the effect on parametric and nonparametric tests using ordinal data when the distances between points changed on the measurement scale. The research examined the performance of Type I and Type II error rates using selected parametric and nonparametric tests.

Robustness of the One-Sample Kolmogorov Test to Sampling from a Finite Discrete Population

Description: One of the most useful and best known goodness of fit test is the Kolmogorov one-sample test. The assumptions for the Kolmogorov (one-sample test) test are: 1. A random sample; 2. A continuous random variable; 3. F(x) is a completely specified hypothesized cumulative distribution function. The Kolmogorov one-sample test has a wide range of applications. Knowing the effect fromusing the test when an assumption is not met is of practical importance. The purpose of this research is to analyze the … more

The Role of Workstation-Based Client/Server Systems in Changing Business Processes: a Multiple Case Study

Description: Although several studies question information technology's contribution to productivity, organizations continue to invest in client/server systems (CSSs) particularly as enablers of business process reengineering (BPR). These efforts may be wasted if they do not improve business processes. This study focused on business processes and investigated the role of workstation-based CSSs in changing business processes. A multiple case study of workstation-based CSS databases in three organizations was… more

A Simulation Study Comparing Various Confidence Intervals for the Mean of Voucher Populations in Accounting

Description: This research examined the performance of three parametric methods for confidence intervals: the classical, the Bonferroni, and the bootstrap-t method, as applied to estimating the mean of voucher populations in accounting. Usually auditing populations do not follow standard models. The population for accounting audits generally is a nonstandard mixture distribution in which the audit data set contains a large number of zero values and a comparatively small number of nonzero errors. This study … more

A Study of Differences Perceived by Information Systems Professionals in the Systems Development Job Environment Due to the Use of ICASE Technology

Description: Information systems professionals now face the automation of their own work in integrated computer aided software engineering. Organizations need to achieve all the leverage possible from costly IT implementations to enhance competitiveness, profitability, and survival in a rapidly changing environment. ICASE technology is a part of the infrastructure necessary to meet this challenge but appears to present significant difficulties in implementation.
