The Interactions Among Information Technology Organizational Learning, Project Learning, And Project Success, Donald Stuart Mckay

CCAC Theses and Dissertations

Knowledge gained from completed information technology (IT) projects was not often shared with emerging project teams. Learning lessons from other project teams was not pursued because people lack time, do not see value in learning, fear a potentially painful process, and had concerns that sharing knowledge will hurt their career. Leaders could change the situation; however organizational leaders have not seen value in project learning and have not made it a priority. Yet, if a relationship existed among IT project success variables (PSVs) organizational learning factors (OLFs) and project learning practices (PLPs) then IT leaders may take greater interest in …

Automated Support For Model Selection Using Analytic Hierarchy Process, Mario Sarkis Missakian

CCAC Theses and Dissertations

Providing automated support for model selection is a significant research challenge in model management. Organizations maintain vast growing repositories of analytical models, typically in the form of spreadsheets. Effective reuse of these models could result in significant cost savings and improvements in productivity. However, in practice, model reuse is severely limited by two main challenges: (1) lack of relevant information about the models maintained in the repository, and (2) lack of end user knowledge that prevents them from selecting appropriate models for a given problem solving task. This study built on the existing model management literature to address these research …

Interoperability Gap Challenges For Learning Object Repositories & Learning Management Systems, Robert T. Mason

CCAC Theses and Dissertations

An interoperability gap exists between Learning Management Systems (LMSs) and Learning Object Repositories (LORs). Learning Objects (LOs) and the associated Learning Object Metadata (LOM) that is stored within LORs adhere to a variety of LOM standards. A common LOM standard found in LORs is the Sharable Content Object Reference Model (SCORM) Content Aggregation Model (CAM). In contrast, LMSs are independent computer systems that manage and deliver course content to students via a web interface. This research addressed three important issues related to the interoperability gap: (a) a lack of a metadata standard that defined the format of how student assessment …

Computer Music Composition Using Crowdsourcing And Genetic Algorithms, Jessica Faith Keup

CCAC Theses and Dissertations

When genetic algorithms (GA) are used to produce music, the results are limited by a fitness bottleneck problem. To create effective music, the GA needs to be thoroughly trained by humans, but this takes extensive time and effort. Applying online collective intelligence or "crowdsourcing" to train a musical GA is one approach to solve the fitness bottleneck problem. The hypothesis was that when music was created by a GA trained by a crowdsourced group and music was created by a GA trained by a small group, the crowdsourced music would be more effective and musically sound. When a group of …

A Domain Aware Genetic Algorithm For The P-Median Problem, Dennis Vickers

CCAC Theses and Dissertations

The p-median problem is an NP-complete combinatorial optimization problem often used in the fields of facility location and clustering. Given a graph with n nodes and an integer p < n, the p-median problem seeks a set of p medians such that the sum of the distances of the n nodes from their nearest median is minimized. This dissertation develops a genetic algorithm that generates solutions to the p-median problem that improves on previously published genetic algorithms by implementing operators that exploit domain specific information. More specifically, this GA explores the following:

(1) The advantages of using "good" solutions generated using extant heuristics in the initial generation of chromosomes.

(2) The effectiveness of a crossover operation that exchanges centers in the same neighborhood rather than exchanging arbitrarily chosen subsets of centers.

(3) The efficacy of using a biased mutation operator that favors replacing existing medians from less fit chromosomes with non-median nodes from the same neighborhood as the median being replaced.

Using published …

Wiki Behavior In The Workplace: Emotional Aspects Of Content Development, Deborah A. Gears

CCAC Theses and Dissertations

Wikis have been found to be an easy-to-use, low-cost, and Internet-based technology useful in creating and mobilizing knowledge. Wikis hosted within firms (corporate wikis) have become a popular way for employees to share information and collaborate.

Preliminary research suggested that as few as 6% of wiki consumers contributed to the development of wiki pages. Conventional approaches argued that employees judged the costs of participating in wikis (e.g., authoring or changing material, reading messages, following an argument, and posting responses) to exceed the benefits of participating in wikis (e.g., recognition, reputation etc.) - thus many people "lurked" but did not post. …

Developing A Framework For Evaluation Of Corporate Non-Transactional Business-To-Consumer Web Sites: A Descriptive Study, Karen Denise Pate

CCAC Theses and Dissertations

During the soaring information economy of the last decade, organizations spent large sums of money on the development of Web sites without much knowledge of their performance value. In time, organizations realized that measuring Web site performance to determine value was fundamental. For transactional, e-commerce Business-to-Consumer (B2C) Web sites, this effort is straightforward because value is attached to sales. Measuring performance to determine the value of non-transactional B2C Web sites (i.e., sites that provide information, not sales) is more complex.

This study examined the underexplored subject of evaluating non-transactional Web sites. Performance was defined as outcomes ranging from site visitor …

Early Detection Of Online Auction Opportunistic Sellers Through The Use Of Negative-Positive Feedback, Gregory J. Reinert

CCAC Theses and Dissertations

Apparently fraud is a growth industry. The monetary losses from Internet fraud have increased every year since first officially reported by the Internet Crime Complaint Center (IC3) in 2000. Prior research studies and third-party reports of fraud show rates substantially higher than eBay’s reported negative feedback rate of less than 1%. The conclusion is most buyers are withholding reports of negative feedback.

Researchers Nikitov and Stone in a forensic case study of a single opportunistic eBay seller found buyers sometimes embedded negative comments in positive feedback as a means of avoiding retaliation from sellers and damage to their reputation. This …

A Comparison Of The Rule And Case-Based Reasoning Approaches For The Automation Of Help-Desk Operations At The Tier-Two Level, Michael Forrester Bryant

CCAC Theses and Dissertations

This exploratory study investigates the hypothesis that case-based reasoning (CBR) systems have advantages over rule-based reasoning (RBR) systems in providing automated support for Tier-2 help desk operations. The literature suggests that rule-based systems are best suited for problem solving when the system being analyzed is a single-purpose, specialized system and the rules for solving the problems are clear and do not change with high frequency. Case-based systems, because of their ability to offer alternative solutions for a given problem, give help-desk technicians more flexibility. Specifically, this dissertation aims to answer the following questions:

1. Which paradigm, rule-based or case-based reasoning, …
