Examining The Similarities And Differences In Benefits Of School-To-Work As A Workforce Development Strategy: A Study Of Key Stakeholder Involvement Using A Multiple Case Study Approach, Alton Leon Alford

Dissertations

Violence is a significant occupational hazard in the American workplace. Nearly a thousand employees are murdered on the job each year and workplacehomicide has become the leading cause of death for women and the second for men. From 1993 to 1999, there were an average of 1.7 million nonfatal violent victimizations each year, accounting for 18% of all violent crime. Although government employees accounted for 18% of the U.S. workforce, they made up 37% of workplace violence victims.

A review of literature found no unified definition of workplace violence. Recent scientific research regarding this problem is rare, despite its increasing …

Knowledge Discovery And Modeling In Genomic Databases, Michael M. Yin

Dissertations

This dissertation research is targeted toward developing effective and accurate methods for identifying gene structures in the genomes of high eukaryotes, such as vertebrate organisms. Several effective hidden Markov models (HMMs) are developed to represent the consensus and degeneracy features of the functional sites including protein-translation start sites, mRNA splicing junction donor and acceptor sites in vertebrate genes. The HMM system based on the developed models is fully trained using an expectation maximization (EM) algorithm and the system performance is evaluated using a 10-way cross-validation method. Experimental results show that the proposed HMM system achieves high sensitivity and specificity in …

Development And Characterization Of Methodology And Technology For The Alignment Of Fmri Time Series, Carlo Ciulla

Dissertations

This dissertation has developed, implemented and tested a novel computer based system (AUTOALIGN) that incorporates an algorithm for the alignment of functional Magnetic Resonance Image (fMRI) time series. The algorithm assumes the human brain to be a rigid body and computes a head coordinate system on the basis of three reference points that lie on the directions correspondent to two of the eigenvectors of inertia of the volume, at the intersections with the head boundary. The eigenvectors are found weighting the inertia components with the voxel's intensity values assumed as mass. The three reference points are found in the same …

Collaborative Problem Solving And Program Development Model, Joanna Defranco-Tommarello

Dissertations

A model to enhance collaborative problem solving and program development is presented. The collaborative model is a detailed cognitive model that takes into consideration the cognitive and social activities that occur during collaborative problem solving and program development. The cognitive activities required for collaborative problem solving and program development are identified and integrated into a six-stage model. An extensive literature review in the associated fields is presented to show the need for the model described in this dissertation. In addition, a comprehensive study of tools to support collaboration during problem solving and program development was also performed as well as …

The Design, Implementation, And Assessment Of Initial Change And Growth In A Local Voluntary Organization And Its Members, Tracy Ann Weber

Dissertations

Problem. During the past 30 years, Americans have steadily reduced their participation in the traditional forms of community involvement, such as clubs, associations, and organizations, that bring people together to effectively pursue a shared objective. In this postmodern society, leaders of community and nonprofit organizations find they are asking themselves difficult questions about the most effective methods of fulfilling their mission and simultaneously meeting members' changing needs. Participatory volunteer-run organizations, such as a local branch or chapter of a national organization, face many challenges, making it hard to establish and maintain there organizations. They demand great energy of leaders, …

A Rhetorical Analysis Of Theodore Hesburgh's Fund-Raising Speeches For The University Of Notre Dame, Peggie Mathaba Ncube

Dissertations

Problem Statement. Literature reveals that college or university presidents play a key role in raising funds for their institutions. These roles are well documented, and yet many presidents face challenges in raising adequate funds for their institutions. Success stories of some university presidents are recorded, but no research has studied their rhetoric in raising funds in an attempt to uncover their formula for success. One such president is Theodore Hesburgh of the University of Notre Dame.

Methodology. This study assumes a rhetorical design, specifically the Burkean dramatistic approach to analyze Theodore Hesburgh's fund-raising speeches to the alumni of the …

The Roles And Attributes Of Human Resource Leaders During Organizational Restructuring, Alison Anne Brown

Dissertations

Problem. As the number of organizations involved in major restructuring increases, Human Resource (HR) leaders find themselves in a labyrinth of evolving roles. How might they facilitate the organization's desire to successfully wed human needs and experiences to profit expectations and strategies?

Purpose. This qualitative study seeks to increase understanding of the dual role played by human resource leadership, as they are both survivors and facilitators of organizational restructuring. It answers the overarching question: What are the unique contributions made by HR leaders to the organizational restructuring process?

Methodology. Through a purposive sampling process, 11 HR leaders were identified who …
