Multivariate Nonnormal Regression Models, Information Complexity, And Genetic Algorithms: A Three Way Hybrid For Intelligent Data Mining, Minhui Liu

Doctoral Dissertations

This dissertation develops a novel computationally feasible intelligent data mining and knowledge discovery technique to select the best subset of predictors in multivariate re- gression (MR) models under the assumption that the random error terms of the model follow a general nonnormal family of distributions. Our approach builds an easy-to-use three way hybrid approach by integrating clever statistical modeling procedures based on the information-theoretic measure of complexity (ICOMP) criterion with genetic algorithm (GA) and multivariate nonnormal regression models with Power Exponential (PE) and fam- ily of elliptically contoured (EC) error distributions. This dissertation is composed of four major parts.

First, …

Stochastic Optimization Models For Contingency Allocation In Project Management, Barbara Maria Thibadeau

Doctoral Dissertations

In many cases, risks that threaten successful project completion can be mitigated (or eliminated) with a proper contingency allocation strategy and exacerbated by an improper one. Yet, despite this importance, there is a dearth of research on the cost contingency allocation problem in academic literature. This thesis looks at the cost contingency allocation problem from two different perspectives and two distinct solutions are introduced: a stochastic linear programming model that addresses a short term strategy and convex-concave utility model that provides a long-term planning solution.

The project manager’s ability to approve random requests for contingency is dependent on several constraints, …

The Role Of Logistics Service Quality In Creating Customer Loyalty, Elizabeth Ruth Davis

Doctoral Dissertations

The purpose of this dissertation is to examine the loyalty phenomenon and to understand the role of logistics service in creating customer loyalty. The main objective is to help companies assess the impact of logistics service in creating loyalty. Logistics service quality is purported to consist of two separate constructs – relational LSQ and operational LSQ. These elements of LSQ drive satisfaction. This research also explores the loyalty phenomenon, which is conceptualized as a causal relationship between affective commitment and purchasing behavior. The strength of this relationship is proposed to be moderated by calculative commitment, which involves the calculation of …

Impact Of Inter-Organizational Influence Communication Strategies On Target Firm Relationship Satisfaction: An Empirical Study Of The Food And Chemical Industry In Thailand, Thaweephan Leingpibul

Doctoral Dissertations

Influence is the way people utilize power. Inter-organizational influence occurs when businesses want to get their way with their partners. As the business environment becomes more complex, organizations within a supply chain realize that in many instances they walk a fine line between exercising their power and yet maintaining good long-term relationships. However, researchers in this area have not provided a clear picture of how to produce those results. Since different types of influence strategies exist, businesses need to recognize the consequences of each of the strategies toward the relationship. This entails recognizing the need for understanding how the target …

An Investigation Into The Nature Of The Relationship Of Corporate Culture To Logistics Outsourcing Decisions, John Edmund Mello

Doctoral Dissertations

The purpose of this research was to investigate the relationships between corporate culture and logistics outsourcing. Using primarily depth interviews, data was collected from twenty-eight participants from three companies. Grounded theory methodology was utilized to interpret the data. Models were developed that provide frameworks for understanding the role cultural orientations take in influencing the “perform versus buy” decision in logistics outsourcing in the participating companies, and in the approaches those firms take regarding the relationships they develop with logistics suppliers.

The findings of the research indicate that, for the participating companies, cultural orientations concerning control and transactional/relational exchange influence the …

Essays On Quantitative Analysis Of Supply Chain Structures, Contracts And Coordination, Xinjie Shi

Doctoral Dissertations

This thesis consists of three separate, but related, essays that deal with the topic of how supply chain structure as well as the use of contracts impact performance of a supply chain. The main focus is the analysis of behavior of indirect-sale supply chains in terms of relative bargaining power and decision rights of the participants. Modeling as Stackelberg games, this thesis explores the existence of Nash equilibriums and the issues surrounding supply chain coordination.

In Essay one, “The Role of Decision Structure in Supply Chain Coordination with Stochastic Demand”, the analysis focuses on how different supply chain structures affect …

The Determinants Of Executive Compensation In The Commercial Banking Industry, David A. Romer

Doctoral Dissertations

The primary purpose of this study is to examine the viability of two basic theories of compensation to explain executive compensation in the banking industry. The two executive compensation motivation theories are sales/sales growth maximization and profit/shareholder wealth maximization. Overall, strong support is found for both theories. This research also seeks to significantly expand, compared to previous research, the number of banks investigated. This study succeeds, with over a four-fold increase in the number of banks analyzed, including over 330 banks not previously used in the literature. This investigation is further motivated by the paucity of banking studies on compensation …

Three Essays On Banking And Corporate Finance, Fang Zhao

Doctoral Dissertations

This dissertation is composed of three essays on banking and corporate finance. The first essay studies the relationship between interest-rate derivative usage and bank lending. Using recent data that cover a full business cycle, this paper documents a direct relationship between interest-rate derivative usage by U.S. banks and growth in their commercial and industrial (C&I) loan portfolios. This positive association holds for interest-rate options contracts, forward contracts, and futures contracts. This result is consistent with the implication of Diamond's model (1984) that predicts that a bank's use of derivatives permits better management of systematic risk exposure, thereby lowering the cost …

Modeling And Simulation Of Value -At -Risk In The Financial Market Area, Xiangyin Zheng

Doctoral Dissertations

Value-at-Risk (VaR) is a statistical approach to measure market risk. It is widely used by banks, securities firms, commodity and energy merchants, and other trading organizations. The main focus of this research is measuring and analyzing market risk by modeling and simulation of Value-at-Risk for portfolios in the financial market area. The objectives are (1) predicting possible future loss for a financial portfolio from VaR measurement, and (2) identifying how the distributions of the risk factors affect the distribution of the portfolio. Results from (1) and (2) provide valuable information for portfolio optimization and risk management.

An Exploratory Study Of The Influence Of Life Management Strategies On Job Satisfaction And Job Performance In A Personal Selling Context, Dheeraj Sharma

Doctoral Dissertations

Extant literature on goal oriented behaviors suggests that individual goal orientation is an important determinant of a salesperson's job satisfaction and job performance. However, the present conceptualization of goal orientation suffers from flawed paradigmatic structure. There are two major disparate paradigms of goal orientation in the extant literature. The first paradigm views goal orientation as a stable personality trait and the second paradigm views it as contextually driven phenomenon. The present study proffers a new approach of conceptualizing individual goal orientation, by introducing the meta-model of Life Management Strategies (Baltes and Baltes, 1998; Freund and Baltes, 1998) in the personal …
