User Acceptance Of E-Commerce Technology: A Meta-Analytic Comparison Of Competing Models, Ali Yayla, Qing Hu
User Acceptance Of E-Commerce Technology: A Meta-Analytic Comparison Of Competing Models, Ali Yayla, Qing Hu
Qing Hu
The Technology Acceptance Model (TAM) and Theory of Planned Behavior (TPB) are widely used in the information systems (IS) literature to explain and predict user technology acceptance behavior. Although these models have been utilized separately in the earlier studies, to increase the richness and predictive power of their studies, scholars have combined both theories in more recent studies. However, few studies have compared these models directly using the same empirical data. The justification for using various hybrid models is mostly anecdotal and convenient rather than based on strong theoretical arguments. Thus the question remains: when studying user technology acceptance behavior, …

Soa Adoption In Practice - Findings From Early Soa Implementations, Christine Legner, Roger Heutschi
Hubert Oesterle
Despite the wide range of advantages which many authors associate with the introduction of a service-oriented architecture (SOA), comprehensive SOA implementations continue to be scarce in practice. Consequently, questions arise as to how the concept is adapted in practice. This paper compares the scientific view of SOA concepts with initial practical experience from first SOA implementations. Based on an SOA model which is derived from recent SOA publications it examines SOA realization in four case studies. From the cross-case analysis, the authors derive three focus areas of SOA adoption, a prioritization of SOA design principles as well as typical steps …

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

Software development traditionally has been a field particularly prone to delays, exceeding budgets, and misunderstandings (May 1998; Connel, 2001; Humphrey, 2002; Goodwin, 2002; Kesteloot, 2003). Only 1/4 of IT projects is completed successfully – i.e. in time, with the assumed cost, and fulfilling the promised functionality (Smith and Keil, 2003). Although there is some improvement over the last years, software creation is still one of the most unpredictable businesses in the world. It should not be surprising then that high-tech environment often is described as stressful an demanding (Kunda, 1992; Hochschild, 1997; Perlow, 1998; Cooper, 2000; Jemielniak, 2005). It is …

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

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
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 …

More Secure Passwords, Scott Magruder, Stanley X. Lewis Jr
Journal of International Technology and Information Management
Passwords are often the first line of defense against hackers trying to logon to a user’s account. Due to this, the password that a user selects for protection of their account is critical. These passwords must be “good” passwords that are not easily cracked. However, how does the network administrator enforce this? A simple change to the login process can make the passwords chosen by users much more secure. A description of this simple process is given in this paper. The normal login process is described. A description of the how hackers attempt to crack passwords is given. The simple …
Improving The Judicial System To Handle Computer Crime, Gerald V. Post, Albert Kagan
Improving The Judicial System To Handle Computer Crime, Gerald V. Post, Albert Kagan
Journal of International Technology and Information Management
This paper asked professionals in the legal system to evaluate the current state and effectiveness of laws to identify and deter computer crime. Responses were evaluated with a formal structural equation model. The results generally show that legal professionals believe potential jurors have minimal knowledge of computer crime issues. More importantly, they also believe that judges have little knowledge or experience. A similar lack of knowledge by defense attorneys indicates that it could be difficult for a person accused of computer related infractions to find adequate representation. On the other hand, more experienced participants do not believe computer laws present …

Integrating It-Enabled Social Networks With Transaction Cost Economics And The Resource Based View Of The Firm, Ganesh D. Bhatt, Jatinder N. D. Gupta, Sushil K. Sharma
Journal of International Technology and Information Management
Prior research has mostly focused on transaction cost economics (TCE) to interpret the effect of information systems (IS) on organizational governance structures. A TCE based approach predicts that information technology (IT) will lead to increased use of electronic markets to coordinate economic transactions from electronic hierarchies. However, there is contradictory evidence in the literature regarding the rise and importance of cooperative relationships, joint ventures, and value-added partnerships integrated through information systems. To reconcile these contradictions, this paper analyzes the effect of IT on governance structures based on the TCE, social network theory, and the resource based view (RBV) of the …
A Framework And Guide For Understanding The Creation Of Consumer Trust, Joseph A. Cazier
A Framework And Guide For Understanding The Creation Of Consumer Trust, Joseph A. Cazier
Journal of International Technology and Information Management
This paper develops a framework and model for building trust by combining research on the creation of trust with the dimensions of trust: ability, benevolence and integrity. By combining these dimensions in a matrix with the types of trust production based on characteristics, process and institutions, the paper develops a robust 3 x 3 matrix with which to categorize and understand trust production. The framework is developed and analyzed in the light of literature on consumer trust. This framework can help researchers, practitioners and consumers understand trust creation and assist businesses in developing a comprehensive strategy for managing trust.
