Bringing The Outside In: Examining The Impacts That Climate, Exchange, And Identity Processes Have On Organizationally-Beneficial Employee Green Behavior, Sashi C. Sekhar
Bringing The Outside In: Examining The Impacts That Climate, Exchange, And Identity Processes Have On Organizationally-Beneficial Employee Green Behavior, Sashi C. Sekhar
Theses and Dissertations
My dissertation contributes to growing practitioner and researcher interest in the corporate social responsibility topic of employee green behavior, a key strategic input to organizational environmental sustainability efforts. While it has been recognized that employee behavior can significantly impact sustainability efforts (Daily, Bishop, and Govindarajulu, 2009; Ones and Dilchert, 2012), the psychological mechanisms through which this occurs and the precise nature of these behaviors have not been rigorously examined. To address the gaps, my research investigates the interrelationship between organizational and individual factors in motivating organizational citizenship behavior directed toward the natural environment (OCB-E). The model, which derives from social …
Statistical Contributions To Operational Risk Modeling, Daoping Yu
Statistical Contributions To Operational Risk Modeling, Daoping Yu
Theses and Dissertations
In this dissertation, we focus on statistical aspects of operational risk modeling. Specifically, we are interested in understanding the effects of model uncertainty on capital reserves due to data truncation and in developing better model selection tools for truncated and shifted parametric distributions. We first investigate the model uncertainty question which has been unanswered for many years because researchers, practitioners, and regulators could not agree on how to treat the data collection threshold in operational risk modeling. There are several approaches under consideration—the empirical approach, the “naive” approach, the shifted approach, and the truncated approach—for fitting the loss severity distribution. …
Three Essays On The Effects Of Appraisal, Cultural, Emotional, And Cognitive Factors On Information Technologies Acceptance And Use, Chun-Lung Huang
Three Essays On The Effects Of Appraisal, Cultural, Emotional, And Cognitive Factors On Information Technologies Acceptance And Use, Chun-Lung Huang
Theses and Dissertations
In essay 1, we propose a model, which utilized Lazarus and Folkman’s Cognitive Appraisal Theory of Emotion or Appraisal Theory (1984, 1987) as a structural foundation to lay out the nomological relationships among a person’s personal, cognitive, and emotional factors in predicting technology use behaviors. Emotion, likes many social and psychological factors, is challenging to give a full-consensus definition, and has been treated as a polar counterpart of cognition. Lazarus and Folkman’s Appraisal Theory suggested that when a person is facing a (disruptive) event, he or she appraises the possible outcomes (we suppose that appraising is a form of cognitive …
Optimal Pairs Trading Rules, Eric Müller
Optimal Pairs Trading Rules, Eric Müller
Theses and Dissertations
This thesis derives an optimal trading rule for a pair of historically correlated stocks. When one stock's price increases and the other one's decreases, a trade of the pair is triggered. The idea is to short the winner and to long the loser with the hope that the prices of the two assets will converge again. In this thesis the spread of the two stocks is governed by a mean-reverting model. The objective is to trade the pair in such a way as to maximize an overall return. The same slippage cost is imposed on every trade. Furthermore, a local-time …
Determining The Optimal Work Breakdown Structure For Government Acquisition Contracts, Brian J. Fitzpatrick
Determining The Optimal Work Breakdown Structure For Government Acquisition Contracts, Brian J. Fitzpatrick
Theses and Dissertations
The optimal level of Government Contract Work Breakdown Structure (G-CWBS) reporting for the purposes of Earned Value Management was inspected. The G-Score Metric was proposed, which can quantitatively grade a G-CWBS, based on a new method of calculating an Estimate At Completion (EAC) cost for each reported element. A random program generator created in R replicated the characteristics of DOD program artifacts retrieved from the Cost Analysis Data Enterprise (CADE) system. The generated artifacts were validated as a population, however validation at the demographic combination level using an artificial neural network was inconclusive. Comparative WBS forms were created for a …
Predicting Schedule Duration For Defense Acquisition Programs: Program Initiation To Initial Operational Capability, Christopher A. Jimenez
Predicting Schedule Duration For Defense Acquisition Programs: Program Initiation To Initial Operational Capability, Christopher A. Jimenez
Theses and Dissertations
Accurately predicting the most realistic schedule for a defense acquisitions program is an extremely difficult task considering the inherent risk and uncertainties present in the early stages of a program. We use a multiple regression analysis to predict schedule duration in a defense acquisition program. The prediction scope of our research is limited to predicting schedule duration from program initiation to initial operation capability (IOC).We use the data from 56 programs across all services, which was acquired from a SAR database created by RAND. We were able to achieve an R2 of 0.429 and an Adjusted R2 of 0.384 in …
Provision Of Hospital-Based Palliative Care And The Impact On Organizational And Patient Outcomes, Marisa L. Roczen
Provision Of Hospital-Based Palliative Care And The Impact On Organizational And Patient Outcomes, Marisa L. Roczen
Theses and Dissertations
Hospital-based palliative care services aim to streamline medical care for patients with chronic and potentially life-limiting illnesses by focusing on individual patient needs, efficient use of hospital resources, and providing guidance for patients, patients’ families and clinical providers toward making optimal decisions concerning a patient’s care. This study examined the nature of palliative care provision in U.S. hospitals and its impact on selected organizational and patient outcomes, including hospital costs, length of stay, in-hospital mortality, and transfer to hospice. Hospital costs and length of stay are viewed as important economic indicators. Specifically, lower hospital costs may increase a hospital’s profit …
