User Evaluation Of The Performance Of Information Systems, Edward Mahinda

Dissertations

Information technologies (IT) are considered the primary survival factor for many organizations and the most critical success factor in businesses today. To justify the necessary investment in IT, user evaluation of information systems' performance in organizations is a key consideration. This research investigated a comprehensive and convenient means for end users to assess this performance.

Among the existing theories and models on the evaluation of information system performance based on intrinsic technological properties, the Web of System Performance (WOSP) model provides the most comprehensive basis for information system evaluation, and therefore merited further investigation. The research question was how well …

Complex Adaptive Systems Based Data Integration : Theory And Applications, Eliahu Rohn

Dissertations

Data Definition Languages (DDLs) have been created and used to represent data in programming languages and in database dictionaries. This representation includes descriptions in the form of data fields and relations in the form of a hierarchy, with the common exception of relational databases where relations are flat. Network computing created an environment that enables relatively easy and inexpensive exchange of data. What followed was the creation of new DDLs claiming better support for automatic data integration. It is uncertain from the literature if any real progress has been made toward achieving an ideal state or limit condition of automatic …

Leader Delegation And Trust In Global Software Teams, Suling Zhang

Dissertations

Virtual teams are an important work structure in global software development. The distributed team structure enables access to a diverse set of expertise which is often not available in one location, to a cheaper labor force, and to a potentially accelerated development process that uses a twenty-four hour work structure.

Many software teams are partially distributed, that is, part of the team is colocated. Such partially distributed global software teams are an important work structure in software development projects. However, little is known about what affects or improves team members’ motivation and job satisfaction in the partially distributed environment. This …

Wireless Lan 802.11x In U.S. Educational Institutions: Technology Adoption And Digital Divide Perspective, Sang-Baek (Chris) Kang

Dissertations

The current study of wireless local area networks (WLAN) adoption in educational institutions is motivated by three reasons. First, most students are exposed to information technology when they are at K-12 schools. Indeed, educational institutions represent the largest segment in the WLAN market in the United States in terms of the number of adopters. Second, WLAN requires a substantial financial investment before it can enable an "anytime, anywhere" learning environment, and may thereby aggravate the digital divide between rich and poor schools. Third, although WLAN is infrastructure technology, it has different characteristics compared to other infrastructure information technologies; traditional infrastructure …

Viewing processes as sequences of actions, this research conducted two studies to: a) uncover the adoption and influence processes employed by individuals, and b) identify the factors that influence diffusion and assimilation within social networks. The first study, situated at the individual level, involved field interviews with 27 individuals from ten organizations in a …

People-Search : Searching For People Sharing Similar Interests From The Web, Quanzhi Li

Dissertations

On the Web, there are limited ways of finding people sharing similar interests or background with a given person. The current methods, such as using regular search engines, are either ineffective or time consuming. In this work, a new approach for searching people sharing similar interests from the Web, called People-Search, is presented. Given a person, to find similar people from the Web, there are two major research issues: person representation and matching persons.

Sifting Customers From The Clickstream : Behavior Pattern Discovery In A Virtual Shopping Environment, Peishih Chang

Dissertations

While shopping online, customers' needs and goals may change dynamically, based on a variety of factors such as product information and characteristics, time pressure and perceived risk. While these changes create emergent information needs, decisions about what information to present to customers are typically made before customers have visited a web site, using data such as purchase histories and logs of web pages visited. Better understanding of customer cognition and behavior as a function of various factors is needed in order to enable the right information to be presented at the right time. One approach to achieving this understanding is …

A Collaborative, Hierarchical, Incremental, And Problem Solving Information Systems Development Model, Timothy Joseph Burns

Dissertations

The "software crisis" has been a much discussed and debated topic in Information Systems research. A core cause of the crisis is often identified as the methodologies and approaches used to develop information systems. Thus, over the years a multitude of methodologies have emerged in support of quality software. While many of these methodologies have been effective, research has shown that system development is a highly circumstantial process, and that no one methodology can be optimal in every context of every project. It is also a fact that system development practitioners have employed ad hoc approaches to modify formal methodologies …

Institutional Effectiveness : The Integration Of Program Review, Strategic Planning, And Budgeting Processes In Two California Community Colleges, Eileen Knight White

Dissertations

Problem. Effective institutional planning is vital to the ability of community colleges to deliberately respond to external and internal pressures to increase accountability and demonstrate institutional effectiveness. A significant indicator for assessing the effectiveness of a program review process is the use of the outcomes for other institutional purposes such as research, planning, and resource allocation—in other words, informed decision making. In the past, program review, planning, and budgeting processes for the most part have been independent functions or limited in their integration within an institution. The literature provides theories of integration, but little has been written about how …

The Viability Of Is Enhanced Knowledge Sharing In Mission-Critical Command And Control Centers, Sameh A. Sabet

School Web Sites And Teacher Employment Interest, David Theodore Freeman

Dissertations

The Internet has changed the way many organizations, including public and private schools, recruit and select employees. It has also changed the way many people research and pursue employment opportunities, including those seeking positions in education. The school Web site is often the medium of first contact between a school or school district and a potential employee. That first contact can influence the potential employee’s decision to actively pursue employment with a school or a school district.

This research measured the reactions o f preservice teachers who visited three grade-level appropriate school Web sites of “poor,” “average,” and “best” distinction. …

Dissertations

The purpose of this research was to develop and analyze the psychometric properties of Byrd’s Nurse’s Ethical Sensitivity Test (Byrd’s NEST). An instrument to evaluate nurses’ ethical sensitivity in practice by examining choices of action in ethical dilemmas based on nursing virtues: compassion, fidelity to trust, moral courage, justice, self-confidence, resilience, practical reasoning, and integrity (Benner, Tanner, & Chelsa, 1996; Volbrecht, 2002). Benner’s theory of skill acquisition-novice to expert was the theoretical framework for this research which surveyed for correlations between a nurse’s ethical sensitivity and educational level, years of experience, certification, and work setting. Until now, there have been …

Text Mining With Exploitation Of User's Background Knowledge : Discovering Novel Association Rules From Text, Xin Chen

Dissertations

The goal of text mining is to find interesting and non-trivial patterns or knowledge from unstructured documents. Both objective and subjective measures have been proposed in the literature to evaluate the interestingness of discovered patterns. However, objective measures alone are insufficient because such measures do not consider knowledge and interests of the users. Subjective measures require explicit input of user expectations which is difficult or even impossible to obtain in text mining environments.

This study proposes a user-oriented text-mining framework and applies it to the problem of discovering novel association rules from documents. The developed system, uMining, consists of two …

Dynamic Measuring Tools For Online Discourse, Jeffrey S. Saltz

Dissertations

When evaluating participation within an Asynchronous Learning Network (ALN), current best practices include counting messages and reviewing participant surveys. To understand the impact of more advanced dynamic measurement tools for use within an ALN, a web-based tool, known as iPET (the integrated Participation Evaluation Tool), was created. iPET, which leverages Social Network Analysis and Information Visualization techniques, was then evaluated via an empirical study. This research demonstrates that using a tool such as iPET increases participation within an ALN without increasing facilitator workload. Due to the fact that active online discussion is a key factor in the success of an …

Using Content And Process Scaffolds For Collaborative Discourse In Asynchronous Learning Networks, Irene Wong-Bushby

Dissertations

Discourse, a form of collaborative learning, is one of the most widely used methods of teaching and learning in the online environment. Particularly, in large courses, discourse needs to be 'structured' to be effective. Historically, technology-mediated learning (TML) research has been inconclusive with often conflicting results. To address this issue, TML research needs greater breadth and depth in pedagogical grounding. The purpose of this research is to build and test an original, technology-mediated, discourse-centered model called the Asynchronous Learning Network Cognitive Discourse Model (ALNCDM) grounded in pedagogy. Cognitive discourse is defined as discourse on conceptual subject matter. The model is …

Developing An Empirical Basis For Selecting A Strategic-Planning Team From Among Likely Candidates Based On Desired Emotional Intelligence Competencies, Robert Allen Reindel

Dissertations

Problem. Corporate teams are often established to complete assigned tasks as they would relate to planning, product development, process improvements, etc. There seems to be a lack of effective means for selecting team members based on objective criteria. Team-member selection is typically a process based only on the selector's judgment. While testing is a typical way to make hiring decisions, the same process is not used for creating teams.

Purpose of the Study. The purpose of this study was to explore a way of using identified competencies of emotional intelligence to objectively select team members for a strategic-planning initiative.

Method. …

Performance Evaluation Models For Strategic Decision-Making: Towards A Hybrid Model, Geraldina Villalobos Quezada

Dissertations

Performance management systems serve strategic, administrative, and developmental purposes; therefore, their role in an organization cannot be overestimated. As a function of this strategic role, different evaluation models have been developed and implemented by organizations: BSC, CIPP, TQM, Six Sigma, and AOP.

Following a review of current evaluation theory and practice models that focus on improving strategic decision-making in organizations, four research questions were developed that sought to identify the interrelationships, evaluation components, evaluation indicators, data collected to support the evaluation,evaluation implementation protocols, quantitative and qualitative analyses, outcomes, and critical factors of the BSC and CIPP models.

A multiple case …

Identity fraud is identified as a key problem with total losses exceeding fifty two billion dollars (Javelin Strategy and Research 2005). A common denominator in most identity-fraud-prone transactions is the use of a keypad; hence this research focuses on keypad data entry and proposes a biometric solution. Three studies develop, evaluate and investigate the feasibility of this solution.

The first study was done in three stages. Stage one investigated the technical feasibility …

The Effects Of Digital Audio On Social Presence, Motivation And Perceived Learning In Asynchronous Learning Networks, Eunhee Kim

Dissertations

This study explores the possibilities of applying digital audio to the ALN environment, so that students can speak and listen rather than type and read. Two sets of 1x2 field experiments (text vs. digital audio) were conducted with two formats of digital audio -recorded voice messages and narrated Microsoft PowerPoint presentation - used in several NJIT courses conducted via ALN. The perceptions of communication media were measured from two different user perspectives: active use when the subjects created their assignments using prescribed communication media (audio or text) and passive use when the subjects viewed/listened to other students' work.

The perceptions …

Improving Document Representation By Accumulating Relevance Feedback : The Relevance Feedback Accumulation (Rfa) Algorithm, Razvan Stefan Bot

Dissertations

Document representation (indexing) techniques are dominated by variants of the term-frequency analysis approach, based on the assumption that the more occurrences a term has throughout a document the more important the term is in that document. Inherent drawbacks associated with this approach include: poor index quality, high document representation size and the word mismatch problem. To tackle these drawbacks, a document representation improvement method called the Relevance Feedback Accumulation (RFA) algorithm is presented. The algorithm provides a mechanism to continuously accumulate relevance assessments over time and across users. It also provides a document representation modification function, or document representation learning …

Live, Virtual, And Constructive Environments For Performance Support, John Michael Lacontora

Dissertations

As military systems become more complex, the operation and support of these systems becomes intrinsically more difficult. The U.S. Army's current procurement process relies on industry to provide embedded training and performance support tools for the systems they produce. These tools are relatively new and in the early stages of development. As yet, they have failed to meet the needs of the technicians that are required to support these complex systems. Current efforts to provide enabling technologies that enhance the capabilities of automotive maintenance technicians are concentrated in three professional communities. First is the Performance Improvement community where work is …
