Project Management Practices In The Information Technology Departments Of Various Size Institutions Of Higher Education, Charles R. Johnston, David C. Wierschem Jan 2007

Project Management Practices In The Information Technology Departments Of Various Size Institutions Of Higher Education, Charles R. Johnston, David C. Wierschem

Journal of International Technology and Information Management

The demand for information technology at institutions of higher education is increasing at a rapid pace. It is fueled by student, faculty, and administrative needs. This paper examines project management practices at these institutions with respect to the sizes of the institutions. Survey results indicate an emphasis on operational concerns at small and medium size institutions when selecting IT projects. The prominence of the role of project manager and adoption of formal PM tools/techniques by IT departments generally increase with the sizes of the institutions. The importance of having a project plan is recognized by all sizes of institutions of …

An Analysis Of The D Programming Language, Sumanth Yenduri, Louise Perkins, Md. Sarder Jan 2007

An Analysis Of The D Programming Language, Sumanth Yenduri, Louise Perkins, Md. Sarder

Journal of International Technology and Information Management

The C language and its derivatives have been some of the dominant higher-level languages used, and the maturity has stemmed several newer languages that, while still relatively young, possess the strength of decades of trials and experimentation with programming concepts. While C++ was a major step in the advancement from procedural to object-oriented programming (with a backbone of C), several problems existed that prompted the development of new languages. This paper focuses on one such language: D. D was designed as a potential successor to C++, supporting most features of C++’s class design and modifications intended to ease common program …

Comparing The Prioritization Of Erp System Effectiveness Measures By Organizational Actors: A Focus On It Professionals And Business Managers, Princely Ifinedo Jan 2007

Comparing The Prioritization Of Erp System Effectiveness Measures By Organizational Actors: A Focus On It Professionals And Business Managers, Princely Ifinedo

Journal of International Technology and Information Management

Modern organizations adopt Enterprise Resource Planning systems (ERP) to integrate their organizational data resources into unified systems. Researchers tend to concentrate on ERP implementation issues with only a handful studying ERP system effectiveness or success in adopting organizations. In fact, none has studied how key organizational actors prioritize or rank relevant measures or items related to the effectiveness of such systems. This study is designed to fill this gap in research as it aims at investigating how two organizational stakeholder groups, i.e. information technology (IT) professionals and business managers prioritize relevant measures related to ERP systems effectiveness. Using surveys in …

Improving Credit Card Operations With Data Mining Techniques, Malini Krishnamurthi Jan 2007

Improving Credit Card Operations With Data Mining Techniques, Malini Krishnamurthi

Journal of International Technology and Information Management

Consumer credit is ubiquitous and lending poses credit risk – the risk of economic loss due to the failure of a borrower to repay according to the terms of his or her contract with the lender. And so, managing credit risk entails estimating the potential ability of borrowers to repay their debts. Researchers have sought to identify factors that contribute to consumer risk, by using quantitative models. However, the presence of data mining techniques to identify credit risk cannot be ignored. There is a paucity of research to demonstrate the use of data mining techniques in this context, and such …

Internet Industry Competition Dynamics: Peering Limitations, Exposure, And Counter Strategies, Seungjae Shin, Jack E. Tucci Jan 2007

Internet Industry Competition Dynamics: Peering Limitations, Exposure, And Counter Strategies, Seungjae Shin, Jack E. Tucci

Journal of International Technology and Information Management

The Internet industry is vertically integrated with Internet Backbone Providers (IBPs) and Internet Service Providers (ISPs.) Although there are many ISPs and IBPs in each stream, both markets are considered independent oligopolies in that there are a few dominant competitors in each market. It is generally accepted that the Internet industry structure has evolved into a four-tier hierarchical structure. The synergistic and codependent nature of the Internet industry is the key element in understanding the competitive environment in which both IBP’s and ISP’s cooperate. Peering is an efficient way to exchange traffic freely within the access tier, nevertheless competitive constraints …

Discovering Software Reliability Patterns Based On Multiple Software Projects, Yi Liu, Gerald Adkins, Jeng-Foung Yao, Gita Williams Jan 2007

Discovering Software Reliability Patterns Based On Multiple Software Projects, Yi Liu, Gerald Adkins, Jeng-Foung Yao, Gita Williams

Journal of International Technology and Information Management

Discovering patterns that indicate software reliability provides valuable information to software project managers. Software Quality Classification (SQC) modeling is a methodology that can be used to discover reliability patterns of large software projects. However, the patterns found by SQC modeling may not be accurate and robust owing to insufficient information used in the training process. This study compares two genetic programming-based SQC models using different volumes of data. These data were extracted from seven different NASA software projects. The results demonstrate that combining data from different projects can produce more accurate and reliable patterns.

Development Of A Global Measure Of Job Embeddedness And Integration Into A Traditional Model Of Voluntary Turnover, Craig Crossley, Rebecca J. Bennett, Steve M. Jex, Jennifer L. Burnfield Jan 2007

Development Of A Global Measure Of Job Embeddedness And Integration Into A Traditional Model Of Voluntary Turnover, Craig Crossley, Rebecca J. Bennett, Steve M. Jex, Jennifer L. Burnfield

Department of Management: Faculty Publications

Recent research on job embeddedness has found that both on- and off-the-job forces can act to bind people to their jobs. The present study extended this line of research by examining how job embeddedness may be integrated into a traditional model of voluntary turnover. This study also developed and tested a global, reflective measure of job embeddedness that overcomes important limitations and serves as a companion to the original composite measure. Results of this longitudinal study found that job embeddedness predicted voluntary turnover beyond job attitudes and core variables from traditional models of turnover. Results also found that job embeddedness …
