Radical Impact Of Change In Actions And Confidence Index On Reverse Decision Making An Application Based Study, Swatee Trimbak Paithankar

Engineering Management & Systems Engineering Theses & Dissertations

While making decisions under uncertainty, people are often unaware of the logical approach to form the decision process. It is assumed that collecting details, analyzing and evaluating data is enough to make 'proper' decisions. However, past research in the decision making arena has significantly validated that there exists a class of decision problems which is complex, ill-structured and not defined to the level where decision makers can draw logical conclusions based on existing traditional decision approaches. RDM (reverse decision making), one of the novel approaches of decision making under conditions of uncertainty, has shown potential towards addressing some of these …

More Secure Passwords, Scott Magruder, Stanley X. Lewis Jr

Journal of International Technology and Information Management

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

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 …

Internet Entrepreneurship And Economic Growth, Gerald V. Post, John F. Pfaff

Journal of International Technology and Information Management

This paper looks at national attempts to promote economic growth through the Internet. Growth can be driven through service exports or internally through increased service transactions and fostering entrepreneurship. India is often held as an example of service exports, but economic statistics show that India might not be a good example for other nations because net service trade is negative and wages have been economically distorted. Ultimately, developing nations need to find internal growth models. Internal growth could be driven though increased consumption due to improved information, or increased investment expenditures from infrastructure investments.

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.

A Framework For Describing And Classifying Multicriteria Portfolio Selection Problems: An Object-Oriented Approach, Heinz Roland Weistroffer, Charles H. Smith

Journal of International Technology and Information Management

Many decisions require not a single solution alternative, but a set or portfolio of alternatives. For example, a business generally produces not a single product, but a portfolio of products, and a project is tackled not by a single individual, but by a team of individuals. Unfortunately, the portfolio selection problem has been largely neglected in the literature. Though many specific problem environments have been discussed using heuristic, ad hoc methods, no general methodology or theory has been developed. This paper proposes an object-oriented framework to provide a theoretical foundation for future research on the portfolio selection problem.

Uml Activity Diagram Semantics And Automated Gui Prototyping, Nancy Winniford Ashley, Timothy E. Meehan, Norman Carr

Journal of International Technology and Information Management

Extended Activity Semantics (XAS) is a notation which can be used with Unified Modeling Language (UML) activity diagrams to specify user interactions with a system and to automatically generate a prototype of the graphical user interface (GUI) that would be used in these interactions. XAS has been incorporated in a CASE tool, Guibot, which has been developed as a plug-in for Rational Rose, a leading UML tool. The notation and tool address a specific gap in UML – the inability to model user interaction.
