Leadership In Groups: Social Networks And Perceptions Of Formal And Informal Leaders, Mitchell D. Stratton Mar 2006

Leadership In Groups: Social Networks And Perceptions Of Formal And Informal Leaders, Mitchell D. Stratton

Theses and Dissertations

The labors of organizational and behavioral science researchers have resulted in a literature robust in the study of leadership and social networks. Empirical examination of both topics has shown significant organizational outcomes, but breadth is lacking both within and between the disciplines. Studies of leadership have seen the preponderance of the effort focused on formal leaders, while most social network studies examine only one informal structure. Moreover, there exists a paucity of studies, which have sought to examine the interrelationships between leadership and social networks. In an effort to address these voids, this thesis investigated: 1) The concurrent existence of …

Formal And Informal Work Group Relationships With Performance: A Moderation Model Using Social Network Analysis, Benjamin R. Knost Mar 2006

Formal And Informal Work Group Relationships With Performance: A Moderation Model Using Social Network Analysis, Benjamin R. Knost

Theses and Dissertations

Social networks have recently emerged in the management discipline as a unique way of studying individuals groups in organizations. While traditionally used in the analysis of un-bounded networks, applying social network analysis techniques to bounded work groups and organizational teams has become increasingly popular. Past research has established relationships between in-degree social network centrality and individual performance as well as social network density and overall group performance. This field study, conducted at a military training course, attempted to further refine this social network-performance relationship by modeling characteristics of both the formal and informal work group networks in relation to performance …

Hazardous Materials Transportation: A Meta-Analysis Of State Level Policy And Regulations, David J. Pastika Mar 2006

Hazardous Materials Transportation: A Meta-Analysis Of State Level Policy And Regulations, David J. Pastika

Theses and Dissertations

Every day, over 800,000 hazmat transactions take place across the United States. This segment of transportation is expected to grow at a modest two percent a year for the foreseeable future but differences of regulations between the state and Federal level have been a growing concern for both the government and members of the hazmat industry. A patchwork of often inconsistent permits, registration requirements, and hazmat organizational structures at the state level often create barriers to the efficient means of commerce for hazmat carriers and shippers. This thesis explores the history of hazardous regulations since de-regulation of the trucking industry …

Strategic Airlift En Route Analysis To Support The Global War On Terrorism Using A Value Focused Thinking Approach, Marykathryn W. Tharaldson Mar 2006

Strategic Airlift En Route Analysis To Support The Global War On Terrorism Using A Value Focused Thinking Approach, Marykathryn W. Tharaldson

Theses and Dissertations

The Global War on Terrorism (GWOT) has yielded new challenges to the United States' strategic airlift infrastructure. The network of en-route airfields that serve as refueling and maintenance stops were designed primarily to service relatively static Cold War requirements. However, the GWOT has resulted in the need for an infrastructure that is responsive to a highly dynamic environment. This research uses a "value focused" methodology to identify en-route airfield locations that simultaneously maximize cargo throughput capability while possessing a high degree of adaptability to volatile cargo delivery requirements.

Speech Recognition Using The Mellin Transform, Jesse R. Hornback Mar 2006

Speech Recognition Using The Mellin Transform, Jesse R. Hornback

Theses and Dissertations

The purpose of this research was to improve performance in speech recognition. Specifically, a new approach was investigating by applying an integral transform known as the Mellin transform (MT) on the output of an auditory model to improve the recognition rate of phonemes through the scale-invariance property of the Mellin transform. Scale-invariance means that as a time-domain signal is subjected to dilations, the distribution of the signal in the MT domain remains unaffected. An auditory model was used to transform speech waveforms into images representing how the brain "sees" a sound. The MT was applied and features were extracted. The …

An Epidemiological Approach To Terrorism, Kjirstin A. Bentson Mar 2006

An Epidemiological Approach To Terrorism, Kjirstin A. Bentson

Theses and Dissertations

There are many types of models for counterterrorism, explaining different problems that the military faces in the fight against terrorism. This thesis proposes that one of the fundamental assumptions underlying existing models of counterterrorism is that the struggle with terrorists can be understood as a war in the traditional sense of the term. We propose to rethink the struggle against terrorism as a fight against an infection. The epidemic of terrorist ideology within part of the world is a result, from this perspective, of the infectiousness of that ideology. Using the insights of the field of the epidemiology of ideas, …

Bda Enhancement Methodology Using Situational Parameter Adjustments, Michael V. Carras Jr. Mar 2006

Bda Enhancement Methodology Using Situational Parameter Adjustments, Michael V. Carras Jr.

Theses and Dissertations

In the context of close ground combat, the perception of Battle Damage Assessment (BDA) is closely linked with a soldier’s engagement decisions and has significant effects on the battlefield. Perceived BDA is also one of the most complex and uncertain processes facing the soldier in live combat. As a result, the modeling and simulation community has yet to adequately model the perceived BDA process in combat models. This research effort examines the BDA process from a perception standpoint and proposes a methodology to collect the pertinent data and model this perception in the Army’s current force-on-force model, CASTFOREM.

Developing An Aggregate Marginal Cost Per Flying Hour Model For The U.S. Air Force's F-15 Fighter Aircraft, Patrick D. Armstrong Mar 2006

Developing An Aggregate Marginal Cost Per Flying Hour Model For The U.S. Air Force's F-15 Fighter Aircraft, Patrick D. Armstrong

Theses and Dissertations

This thesis applies econometric techniques to build a "marginal" cost per flying hour model for the U.S. Air Force's F-15CD and E fleets. It used monthly economic, programmatic, operational, and climatology data from FY01-FY04 to construct Depot Level Reparable (DLR) and Consumable (CONS) models on the aggregate level. It incorporated the use of panel data analysis to explore the effect each of the independent variables had on the CPFH rate by time and by base. This allowed it to capture not only the temporal (time) interactions, but also the spatial (cross-sectional) interactions, providing a more robust analysis of the dynamics …

Building A Consensus Forecast For Crude Oil Prices, Kenneth W. Burke Mar 2006

Building A Consensus Forecast For Crude Oil Prices, Kenneth W. Burke

Theses and Dissertations

Skyrocketing fuel prices have stressed the Department of Defense's budget in recent years. In 2001 the DoD spent $4.7 Billion on fuel with the Air Force consuming $2.7 Billion. These figures have grown over due to these increases as well as the increased flying ours to support the Global War On Terror. In fact, the Fiscal Year 2007 budget has already been increased by $1.1 billion, or 1% of the total budget, to accommodate the increased price of fuel. Current forecasts of this resource have yielded poor results, impairing the DoD's ability to budget this critical expense. Further because the …

Influence Of Organizational Culture On The Relationship Between Psychological Contracts And Organizational Citizenship Behavior, Jennifer M. Carbajal Mar 2006

Influence Of Organizational Culture On The Relationship Between Psychological Contracts And Organizational Citizenship Behavior, Jennifer M. Carbajal

Theses and Dissertations

The issue of what antecedents of organizational citizenship behavior (OCB) and psychological contracts (PC) employees form with their organization has also been of interest as they have many implications on an employee's extra-role behavior, specifically OCBs. This research investigates the relationship between types of PCs (a) relational and (b) transactional and the propensity to perform (a) altruism and (b) compliance OCB. Furthermore, the influence of organizational culture (OC) dimensions (a) internal orientation and (b) external orientation on this relationship was explored. The results show that transactional PCs were negatively related to both dimensions of OCB. Relational PCs were positively related …

Vulnerabilities To Depression, Anxiety And Interpersonal Problems: The Role Of Parental Styles, Schemas And Coping Styles, Daniel Kennedy Feb 2006

Vulnerabilities To Depression, Anxiety And Interpersonal Problems: The Role Of Parental Styles, Schemas And Coping Styles, Daniel Kennedy

Theses and Dissertations

Cognitive theory proposes that maladaptive schemas influence the development of anxious and depressive symptoms and early parental experiences have been proposed to influence schema development. In this current study, measures of depressive and anxious pathology, parenting styles, coping styles and interpersonal problems were administered to 224 undergraduate students. The main purpose the study was to test the cognitive model and the hypothesis that early maladaptive schemas (EMS) as defined by Young (1994) mediate the relationship between parenting styles and anxious and depressive pathology. Results indicated that EMSs do play an important mediational role in relationship to both anxious and depressive …

Perceptions Of Academic And Social Self-Efficacy Among Adolescents Diagnosed With Cancer And Their Relations With Dispositional Optimism, Perceived Vulnerability, And Treatment Modality, Rebecca Hope Foster Jan 2006

Perceptions Of Academic And Social Self-Efficacy Among Adolescents Diagnosed With Cancer And Their Relations With Dispositional Optimism, Perceived Vulnerability, And Treatment Modality, Rebecca Hope Foster

Theses and Dissertations

For adolescents with cancer, a population notably neglected in the literature, maintaining and strengthening academic and social self-efficacy is especially salient in terms of promoting positive adaptation on key developmental indices. Based on prior research citing their potential roles among adolescents adapting to cancer, treatment modality, dispositional optimism, and perceived vulnerability were chosen as variables likely related to social and academic self-efficacy. Forty-two adolescents diagnosed with cancer and at least six months post-treatment completed questionnaire packets. Analyses indicated that although treatment modality did not relate to academic or social self-efficacy, prognosis should be considered as a covariate. Hierarchical regression analyses …
