The Emperor of Ice Cream Visits Eudora Welty: The Uses of the Creative Imagination

Description: Eudora Welty and Wallace Stevens share important aesthetic beliefs, especially regarding uses of the creative imagination by artists in acts of creation and characters in acts of living. A close reading of seventeen of Welty's stories, accompanied by references to related ideas in many of Stevens' poems, reveals how the imagination functions as epistemology and eucharist, while governing the shape of individual human views of the quotidian. The more abstract patterns of thought in their later works seem to move Welty closer to belief in a world beyond the quotidian than they do Stevens.

An Empirical Analysis of Stock Market Anomalies and Spillover Effects: Evidence from the Securities Exchange of Thailand

Description: This study examines two interrelated but separate issues: cross-sectional predictability of equity returns in the Stock Exchange of Thailand (SET), and transmission of stock market movements. The first essay empirically investigates to what extent the evidence of three major documented stock market anomalies (earnings-price ratio, firm size, and book-to-market ratio) can be generalized across national stock markets. The second essay studies the price and volatility spillover effects from the New York Stock Exchange (NYSE) to the SET. The first essay, using the Fama-Macbeth procedure and the pooled time-series cross-sectional GLS regressions, finds a weak relation between the beta and average stock returns. The adjustment of estimated beta for the effect of thin trading does not change the implications of the results. Of the three anomalies investigated, the size effect has the most prominent and consistent role in explaining average returns. For the earnings-price ratio, the results indicate that the significance of the E/P ratio variable persists only if the nonfinancial firms are considered. In contrast to the previous empirical results for the U.S. and Japanese stock markets, the book-to-market ratio fails to explain the SET equity returns. The second essay employs a generalized autoregressive conditionally heteroskedastic (GARCH) model with conditional t-distributed errors to investigate the spillover effects. No evidence of price spillover effects is found for the full sample period. However, the spillover effects are significant during the period in which the Federal Reserve Board raised interest rates. Further examinations reveal that information inferred from price changes in the U.S. market influences only the opening price in the SET, not the open-to-close Thai stock market returns. This implies that price in the SET is informationally efficient with respect to the price determined in the U.S. stock market. The evidence is generally supportive of international financial integration and informational efficiency in ...

An Empirical Comparison of Random Number Generators: Period, Structure, Correlation, Density, and Efficiency

Description: Random number generators (RNGs) are widely used in conducting Monte Carlo simulation studies, which are important in the field of statistics for comparing power, mean differences, or distribution shapes between statistical approaches. Statistical results, however, may differ when different random number generators are used. Often older methods have been blindly used with no understanding of their limitations. Many random functions supplied with computers today have been found to be comparatively unsatisfactory. In this study, five multiplicative linear congruential generators (MLCGs) were chosen which are provided in the following statistical packages: RANDU (IBM), RNUN (IMSL), RANUNI (SAS), UNIFORM(SPSS), and RANDOM (BMDP). Using a personal computer (PC), an empirical investigation was performed using five criteria: period length before repeating random numbers, distribution shape, correlation between adjacent numbers, density of distributions and normal approach of random number generator (RNG) in a normal function. All RNG FORTRAN programs were rewritten into Pascal which is more efficient language for the PC. Sets of random numbers were generated using different starting values. A good RNG should have the following properties: a long enough period; a well-structured pattern in distribution; independence between random number sequences; random and uniform distribution; and a good normal approach in the normal distribution. Findings in this study suggested that the above five criteria need to be examined when conducting a simulation study with large enough sample sizes and various starting values because the RNG selected can affect the statistical results. Furthermore, a study for purposes of indicating reproducibility and validity should indicate the source of the RNG, the type of RNG used, evaluation results of the RNG, and any pertinent information related to the computer used in the study. Recommendations for future research are suggested in the area of other RNGs and methods not used in this study, such as additive, combined, ...

An Empirical Evaluation of Communication and Coordination Effectiveness in Autonomous Reactive Multiagent Systems

Description: This thesis describes experiments designed to measure the effect of collaborative communication on task performance of a multiagent system. A discrete event simulation was developed to model a multi-agent system completing a task to find and collect food resources, with the ability to substitute various communication and coordination methods. Experiments were conducted to find the effects of the various communication methods on completion of the task to find and harvest the food resources. Results show that communication decreases the time required to complete the task. However, all communication methods do not fare equally well. In particular, results indicate that the communication model of the bee is a particularly effective method of agent communication and collaboration. Furthermore, results indicate that direct communication with additional information content provides better completion results. Cost-benefit models show some conflicting information, indicating that the increased performance may not offset the additional cost of achieving that performance.

Empirical Evidence of Pricing Efficiency in Niche Markets

Description: Unique and proprietary data of the illiquid, one-year non cancelable for three month Bermudan swaps (1Y NC 3M swaps) and one-year non callable for three months Bermudan CDs (1Y NC 3M CDs), provides evidence of market efficiency. The 1Y NC 3M swap and 1Y NC 3M CD markets efficiently reflected unexpected economic information. The 1Y NC 3M swaption premiums also followed the European one-year into three-month (1Y into 3M) swaption volatilities. Swaption premiums were computed by pricing non-optional instruments using the quoted 1Y NC 3M swap rates and the par value swap rates and taking the difference between them. Swaption premiums ranged from a slight negative premium to a 0.21 percent premium. The average swaption premium during the study period was 0.02 percent to 0.04 percent. The initial swaption premiums were over 0.20 percent while the final swaption premiums were 0.02 percent to 0.04 percent. Premiums peaked and waned throughout the study period depending on market uncertainty as reflected in major national economic announcements, Federal Reserve testimonies and foreign currency devaluations. Negative swaption premiums were not necessarily irrational or quoting errors. Frequently, traders obligated to provide market quotes to customers do not have an interest and relay that lack of interest to the customer through a nonaggressive quote. The short-dated 1Y NC 3M swaption premiums closely followed 3M into 1Y swaption volatilities, indicating the 3M into 1Y swaption market closely follows the 1Y NC 3M swaption market and that similar market factors affect both markets or both markets efficiently share information. Movements in 1Y NC 3M swaption premiums and in 3M into 1Y swaption volatilities reflected a rational response by market participants to unexpected economic information. As market uncertainty decreased in the market place, risk measured both by swaption premiums and swaption volatilities decreased; vice verse when economic factors showed ...

An Empirical Examination of Service Dominant Logic: The Theory of the Network

Description: Marketing scholars question the ability of the 4Ps to explain higher order phenomena in modern marketing. Scholars contend that marketing's historical framework, based in product centric economic theory, constrains the 4Ps ability to form a foundation for a general theory of marketing. The focus on value embedded in product fails to explain knowledge-based intangible sources of competitive advantage. In response to this concern a new dominant logic for marketing called service-dominant logic (S-D Logic) has been proposed. However, not all scholars are supportive of S-D Logic. Still nescient, S-D Logic lacks a theoretic model, operationalized constructs, and relationships between those constructs. This study addresses those deficiencies by: (1) generation of a grounded theory of a performance-oriented network; (2) empirical assessment of the S-D Logic literature; and (3) development of an inductively generated theory of S-D Logic to include constructs, relationships, outcomes, and hypothesis. This investigation provides an important set of research findings. The resultant service-oriented network theory suggests a theoretic structure for S-D Logic. Use of grounded theory provides a strong empirical foundation based in a leading edge multi-national market segment composed corporations and programs worth hundreds of billions of dollars. The analysis drew upon 44 field interviews and follow-up exchanges. Multiple member checking sessions generated practitioner confirmation of the research conclusions. The work provides actionable theoretical and practical implications. This investigation provides a link between S-D Logic as a foundation for a general theory of marketing and initial model of suggestive of such theory. For the practitioner the service-oriented network model provides actionable constructs. The antecedents identified are largely influencable by inter-firm leadership and provides them a mechanism to tailor the specific service-oriented strategy to support the desired network value propositions.

An Empirical Examination of the Effects of FASB Statement No. 52 on Security Returns and Reported Earnings of U.S.-Based Multinational Corporations

Description: Prior to the issuance of Financial Accounting Standards Board Statement No. 8 (SFAS No. 8), there was a marked inconsistency in the area of accounting for foreign currency translation. Though designed to make the diverse accounting practices of multinational corporations (MNCs) more compatible, SFAS No. 8 was the subject of a great deal of criticism, eventually leading to the issuance of Financial Accounting Standards Board Statement No. 52 (SFAS No. 52). SFAS No. 52 differs from SFAS No. 8 on objectives and method of translation, and on accounting treatments of translation adjustments. This dissertation provides an empirical examination of the security market reaction to the accounting policy change embodied in SFAS No. 52, and its impact on the volatility of reported earnings of MNCs. The effects of the issuance and early adoption of SFAS No. 52 on security return distributions were determined by both cross-sectional comparisons of cumulative average residuals (CAR) between MNCs and domestic firms and between early and late adopters, and by time-series tests on CAR of MNCs. Two volume analyses were performed to test the effects of SFAS No. 52 on security volume. The first analysis was adjusted to remove the effects of the marketwide factors on volume, and the second analysis was unadjusted for the market influences. Four nonparametric tests were used in testing the effects of SFAS No. 52 vis-a-vis SFAS No. 8 on the volatility of reported earnings of MNCs. The findings of this study led to the following conclusions: (1) SFAS No. 52 had significantly affected security returns of MNCs, but had no significant effects on security volume of MNCs; (2) the early adoption of SFAS No. 52 had no effects on security returns and volume of early adopters as opposed to late adopters; and (3) SFAS No. 52 did not have any ...

An Empirical Investigation of Critical Factors that Influence Data Warehouse Implementation Success in Higher Educational Institutions

Description: Data warehousing (DW) in the last decade has become the technology of choice for building data management infrastructures to provide organizations the decision-making capabilities needed to effectively carry out its activities. Despite its phenomenal growth and importance to organizations the rate of DW implementation success has been less than stellar. Many DW implementation projects fail due to technical or organizational reasons. There has been limited research on organizational factors and their role in DW implementations. It is important to understand the role and impact of both technical but organizational factors in DW implementations and their relative importance to implementation performance. A research model was developed to test the significance of technical and organizational factors in the three phases of implementation with DW implementation performance. The independent variables were technical (data, technology, and expertise) and organizational (management, goals, users, organization). The dependent variable was performance (content, accuracy, format, ease of use, and timeliness). The data collection method was a Web based survey of DW implementers and DW users sampled (26) from a population of 108 identified DW implementations. Regression was used as the multivariate statistical technique to analyze the data. The results show that organization factors are significantly related to performance. Also, that some variables in the post-implementation phase have a significant relationship with performance. Based on the results of the tests the model was revised to reflect the relative impact of technical and organizational factors on DW performance. Results suggest that in some cases organizational factors have a significant relationship with DW implementation performance. The implications and interpretation of these results provide researchers and practitioners' insights and a new perspective in the area of DW implementations.

An Empirical Investigation of Detail Design Tools and Cognitive Style of Software Developers

Description: The purpose of this study is to identify what detail design tools are more productive for the different types of professional software developers. By establishing a match between the detail design tool and the cognitive style of the professional programmer, the end product (Information Systems) should be of a higher quality. Two laboratory experiments were conducted. The first experiment was with professional Software Developers; the second one was with students. The dependant variables considered in this study were the number of semantic errors and the time required to complete a design task for conditional logic. The independent variables were the cognitive style of the subject, the complexity of the task, and the detail design tools. Decision trees, flowcharts and pseudocode were used as detailed design tools. Field dependence was the only dimension of cognitive style that was tested.

An empirical investigation of how perceived devaluation and income effects influence consumers' intended utilization of savings from coupon redemption.

Description: Coupons are one of the most popular and attractive tools of promotion. Redeeming coupons makes shoppers feel that they are doing something good for their family's budget, because coupons offer 'savings.' On the other hand, a coupon might have several negative effects on purchase behavior as well, which might 'devalue' the promoted product in the consumer's perception. But a review of the literature shows a lack of attention afforded to the above-mentioned aspects of coupon redemption. In addition, the consumer's coupon redemption behavior is moderated by several factors drawn from research in the fields of market pricing, economics and psychology, each of which have contributed to the current study in their own way. Finally, there does not exist any substantive research as to why coupon redemption rates have been on the decline, despite an increase in distribution of coupons. Therefore, this research not only fills existing gaps in the literature but also enriches it by synthesizing views from different academic disciplines. This dissertation concentrates on grocery products. Data is collected from about 2500 adults, primarily residing in the Dallas-Fort Worth area. The conceptual framework is based on the theory of reasoned action, which suggests that an individual's beliefs influence his/her attitude towards the consequences of actions, and attitudes, in turn, influence the individual's actions. Toward this end, the model incorporates intention to redeem coupons, intention to keep or spend savings and intention of how to spend savings from coupon redemption as the dependent variables, and several other independent variables. Behavioral independent variables are measured using items borrowed from established scales, as well as those developed exclusively for the current study. Standard statistical tools such as factor analysis and accepted measures of reliability and validity (Cronbach's alpha) are applied and reported, while structural equation modeling has been used to re-validate certain ...

An empirical investigation of manufacturing flexibility and organizational performance as moderated by strategic integration and organizational infrastructure.

Description: The purpose of this study is empirically investigating four research questions related to manufacturing flexibility. 1) What are the components of manufacturing flexibility? 2) Is there a relationship between manufacturing flexibility and organizational performance? 3) Do integrated strategies strengthen the relationship between manufacturing flexibility and organizational performance? 4) Are there organizational characteristics that strengthen the relationship between manufacturing flexibility and organizational performance? This study used a cross-sectional survey design to collect data from manufacturing organizations in multiple industries. Organizational performance was quantified using common manufacturing measures. Strategic integration and organizational infrastructure were also measured. Data were collected using a self-administered questionnaire. Factor analysis, correlation analysis, and regression were used to analyze the data. The results indicate the variables and expected relationships exist as hypothesized. This study contributes to the manufacturing flexibility body of knowledge by identifying relationships between the manufacturing flexibility component, performance, strategic integration, and organizational infrastructure. The instrument development in this study is of particular value as there are few rigorously developed and validated instruments to measure the manufacturing flexibility components and performance. Understanding these relationships will help practitioners make better decisions in manufacturing organizations as well as enable application of the concepts in this study to other contexts such as service organizations.

An Empirical Investigation of Personal and Situational Factors That Relate to the Formation of Entrepreneurial Intentions

Description: New entrepreneurial organizations emerge as a result of careful thought and action. Therefore, entrepreneurship may be considered an example of planned behavior. Previous research suggests that intentions are the single best predictor of planned behavior. Given the significance of intentions, the purpose of this study was to investigate the relationships between the personal characteristics of the entrepreneur and perceived environmental factors, and entrepreneurial intentions.

An Empirical Investigation of Personality and Situational Predictors of Job Burnout

Description: Empirical research exploring the complex phenomenon of job burnout is still considered to be in its infancy stage. One clearly established stream of research, though, has focused on the antecedents of the three job burnout components: emotional exhaustion, depersonalization, and personal accomplishment. In particular, situational characteristics have received a great deal of attention to date. Four situational factors: (1) role ambiguity, (2) role conflict, (3) quantitative role overload, and (4) organizational support were included in this analysis to test their significance as predictors of job burnout. Another set of antecedents that has received far less attention in job burnout research is personal dispositions. Individual differences, most notably personality traits, may help us understand why some employees experience burnout whereas others do not, even within the same work environment. Four personality characteristics: (1) self-esteem, (2) locus of control, (3) communal orientation, and (4) negative affectivity were included to test their significance as predictors of job burnout. An on-site, self-report survey instrument was used. A sample of 149 human service professionals employed at a large government social services department voluntarily participated in this research. The main data analysis techniques used to test the research hypotheses were canonical correlation analysis and hierarchical analysis of sets. While role ambiguity showed no significant associations with any of the three job burnout components, the remaining situational factors had at least one significant association. Among all the situational characteristics, quantitative role overload was the strongest situational predictor of emotional exhaustion and depersonalization, while organizational support was the strongest situational predictor of personal accomplishment. The personality predictor set as a whole showed a significant relationship with each of the job burnout components, providing strong proof that dispositional effects are important in predicting job burnout. Among all the personality characteristics, negative affectivity was the strongest personality predictor of emotional ...
