A Mixed Methods Study: Evaluating The Relationship Of Project Manager Competencies And It Project Management Methodologies, Keith A. Mcdermott Dec 2016

A Mixed Methods Study: Evaluating The Relationship Of Project Manager Competencies And It Project Management Methodologies, Keith A. Mcdermott

Open Access Theses

Determining skillsets that are particularly important to the development of an effective project manager can be useful for a variety of applications. These applications range from the hiring of a new project manager for an organization to continued training for current employees. Past research has called upon current project managers to rate what skillsets they see as important to the cultivation of an optimal or effective project manager. Additional research has expanded this idea to determine how skillsets vary between project managers and functional managers (El-Sabaa, 2001). While this research is certainly important, skillset grouping can be further explored. This …

Service Improvement And Cost Reduction For Airlines: Optimal Policies For Managing Arrival And Departure Operations Under Uncertainty, Heng Chen

Doctoral Dissertations

Annual U.S. air travel demand has been growing steadily by 4-5% over the last decade, and it is estimated that the demand will nearly double in the next twenty years. It has also been estimated by the International Civil Aviation Organization that global demand for commercial aircraft will increase at an average annual rate of 4.1% by 2034 (IATA, 2014). However, airport expansions and aviation infrastructure upgrades have not kept pace with the increase in air traffic demand, as only 3% of all the new airport projects around the world are planned in the U.S. (CAPA, 2015). Thus, the operation …


Network Game Theory Models Of Services And Quality Competition With Applications To Future Internet Architectures And Supply Chains, Sara Saberi Nov 2016

Network Game Theory Models Of Services And Quality Competition With Applications To Future Internet Architectures And Supply Chains, Sara Saberi

Doctoral Dissertations

The Internet has transformed the way in which we conduct business and perform economic and financial transactions. One key challenge of the Internet is the inefficiency of the mechanisms by which technology is deployed and the business and economic models surrounding these processes (Wolf et al. (2014)). Equilibrium models for the Internet generally assume basic economic relationships. However, in new paradigms for the Internet and in supply chain networks, price is not the only factor; quality of service (QoS) is also of increasing importance. Supply chains networks, which give us the means to manufacture products and deliver them to points …

Effects Of An Integrated Electronic Health Record On An Academic Medical Center, Kenneth E. Koppenhaver Ii

Walden Dissertations and Doctoral Studies

The debate about healthcare reform revolves around a triple aim of improving the health of populations, improving the patient experience, and reducing the cost of care. A major tool discussed in this debate has been the adoption of electronic health record (EHR) systems to record and guide care delivery. Due to low adoption rates and limited examples of success, the problem was a lack of understanding by healthcare organizations of how the EHR fundamentally changes an organization through the interactions of people, processes, and technology over time. The purpose of this case study was to explore the people, processes, and …

Ceo Ownership And Firm Performance: Evidence From The 2003 Dividend Tax Cut, Hong Kim Duong Jan 2016

Ceo Ownership And Firm Performance: Evidence From The 2003 Dividend Tax Cut, Hong Kim Duong

Open Access Theses & Dissertations

This study investigates whether and how CEO ownership impacts firm performance by using the large tax cut on individual dividend income enacted in 2003 (The 2003 Dividend Tax Cut) as an exogenous shock. My findings suggest that CEO ownership of dividend payers significantly increased after the shock in the form of higher annual restricted stock grants and more option exercises. I document that the change in CEO ownership has an asymmetric impact on firm performance and investment efficiency. Only dividend payers with CEOs who moved closer to optimal ownership experienced improvement in investment efficiency and performance. In contrast, dividend payers …

Predictive Factors Of Organizational Support Communication In Volunteer Mentor Retention, Jennifer Kristin Stukey Jan 2016

Predictive Factors Of Organizational Support Communication In Volunteer Mentor Retention, Jennifer Kristin Stukey

Walden Dissertations and Doctoral Studies

Research has shown that long-term volunteer retention is critical for sustaining the viability of youth mentoring programs such as Big Brothers Big Sisters (BBBS). Data from recent studies have indicated that volunteers must continue their service for at least 1 year in to have a sustainable effect on the mentee. Results from prior studies have indicated that the support provided by the agency to the volunteer can predict volunteer retention. However, a gap in current literature exists regarding the effect of support communication on volunteer retention. Therefore, the purpose of this quantitative study was to assess the relationship between organizational …


Knowledge Sharing Intentions In Wholesale Distribution Organizations, Andrew E. Roth Jan 2016

Knowledge Sharing Intentions In Wholesale Distribution Organizations, Andrew E. Roth

Walden Dissertations and Doctoral Studies

Millions of American employees are eligible to retire through 2026, which may contribute to lowered organizational performance stemming from the resultant void in knowledge. Increasing knowledge sharing (KS) among organizational members may improve employee efficiency and company performance, and therefore may be of value to wholesale distribution leaders. Although researchers have suggested that sense of self-worth, subjective norms, and attitudes influence employees' inclinations to share knowledge, researchers have not analyzed the relationships between a subset of predictor variables and KS intentions in wholesale distribution organizations. The purpose of this correlational study, grounded in the theory of planned behavior, was to …

Leadership Styles And Learning For Performance Within Commercial Banks In Kenya, Teckie Michelle Karoki Jan 2016

Leadership Styles And Learning For Performance Within Commercial Banks In Kenya, Teckie Michelle Karoki

Walden Dissertations and Doctoral Studies

The literature indicates that leaders influence the establishment of organizational learning culture (OLC) by the application of transformational (TFO), transactional (TAC), and passive-avoidant (PAV) styles. Further, the literature links OLC to the financial performance of organizations by leadership involvement in establishing learning organizations. However, the manner in which the practice of OLC occurs and the relationship of OLC with TFO, TAC, and PAV is unclear, as is the link between OLC and financial performance (ROA); especially for growing economies outside North America. The purpose of this study was to address this gap in the literature through a quantitative study of …
