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 ...

An Empirical Investigation of Portfolios with Little Idiosyncratic Risk

Description: The objective of this study is to answer the following research question: How large is a diversified portfolio? Although previous work is abundant, very little progress has been made in answering this question since the seminal work of Evans and Archer (1968). This study proposes two approaches to address the research question. The first approach is to measure the rate of risk reduction as diversification increases. For the first approach, I identify two kinds of risks: (1) risk that portfolio returns vary across time (Evans and Archer (1968), and Campbell et al. (2001)); and (2) risk that returns vary across portfolios of the same size (Elton and Gruber (1977), and O'Neil (1997)). I show that the times series risk reaches an asymptote as portfolio size increases. Cross sectional risk, on the other hand, does not appears to reach an asymptote as portfolio size increases. The second approach consists of comparing portfolios' performance to a benchmark portfolio that is assumed to be diversified (Statman (1987)). I develop a performance index. The performance index is calculated, for any given test portfolio, as the ratio of the Sharpe-like measure of the test portfolio to the Sharpe-like measure of the benchmark portfolio that is assumed to be diversified. The index is based on the intuition that an increase in portfolio size reduces times series risk and cross sectional risk, and increases transaction costs. Portfolio size is worth increasing as long as the marginal increase in the performance index from a decrease in risk is greater than the marginal decrease of the performance index from an increase in transaction costs. Diversification is attained when the value of the index reaches one. The results of my simulations indicate that the size of a well diversified portfolio is at the very least 30. This number can be ...

An Empirical Investigation of Psychophysiological Characteristics and Psychological Variables in Information Systems Human Factors Research

Description: The purpose of this study was to test the comparability of several psychological instruments commonly used in Information Systems (IS) cognitive style research. The objective was to determine the limitations of: existing instruments in IS cognitive style research. The motivation for this research was the inconclusive findings reported in IS human information processing research. The study used a repeated measures design. Each individual completed the following cognitive style and personality instruments; the Myers-Briggs Type Indicator, the Group Embedded-figures Test, the Learning Style Inventory, the Human Information Processing Survey, and the Torrance Tests of Creative Thinking (Figural Form A). The individual also completed a dichotic listening and tachistoscope task. Data was collected from business administration, BCIS, liberal arts majors, and IS professionals. The results of this study indicate IS researchers need to consider several factors in the use of these instruments. A direct relationship exists between cognitive ability and results on the GEFT. Cognitive ability should be considered a moderating variable in interpreting the results of the GEFT. Also, the hypothesis that the GEFT is a surrogate for analytical and low-analytical abilities is not supported by this study. Other reported results include the inappropriateness of using the TTCT with adult populations. Also, the MBTI appears to be an appropriate instrument for measuring cognitive styles in IS research. This study reported that gender is a moderating factor on the classification of MBTI types in that gender is not evenly divided among feeling and thinking types. This study reported no relationships between the cognitive style and personality instruments with the physiological measurements. The validity of the physiological measurements could be the underlying factor for not reporting any significant relationships. IS researchers will benefit from this study through an improved understanding of the appropriateness and applicability of these instruments. This benefits research through the ...

An Empirical Investigation of the Discriminant and Predictive Ability of the SFAS No. 69 Signals for Business Failure in the Oil and Gas Industry

Description: In 1982, the Financial Accounting Board (FASB) issued Statment of Financial Accounting Standards No. 69 (SFAS No. 69) which required oil and gas producing companies to disclose supplementary information to the basic financial statements. These disclosures include, costs incurred, capitalized costs, reserve quantities, and a standardized measure of discounted cash flows. The FASB considered these disclosures to be necessary to compensate for the deficiencies in historical cost financial statements. The usefulness of the new signals created by SFAS No. 69, however, is an empirical question and research regarding that objective is lacking. The objective of the study is to test the usefulness of SFAS No. 69. The research strategy used to achieve that objective is to compare the discriminant and predictive power of SFAS No. 69 signals or SFAS No. 69 signals combined with financial signals to that of financial signals alone. The research hypothesized that SFAS No. 69 signals by themselves or as supplmentary to financial signals have more discriminant and predictive ability for business failure in oil and gas industry than do financial signals alone. In order to test that hypothesis, the study used the multiple discriminant analysis technique (MDA) to develop three equations. The first is based on SFAS NO. 69 signals, the second on financial statement signals, and the third on joint financial and SFAS No. 69 signals. Data were collected from the 10-K's arid the annual reports of 28 oil and gas companies (14 failed and 14 nonfailed). The analysis was repeated for four time bases, one year before failure, two years before failure, three years before failure, and the average of the three years immediately before failure. After assessing the discriminant and predictive ability of each equation in the four time bases, a t-test was used to determine a significant difference in the discriminant ...

An Empirical Investigation of the Effectiveness of Using Assigned, Easy Goals to Strengthen Self-efficacy Perceptions and Personal Goals in Complex Task Performance

Description: The perception of self-efficacy is a central cognitive construct in explaining motivation. Assigned goals are established in the literature as affecting self-efficacy, but only a few researchers investigated their effects in complex tasks. One stream of research revealed the positive effects of easy goals on performance in a complex task without regard to self-efficacy perceptions. In the present study, the focus was on the effects of assigned, easy goals on self-efficacy and personal goals in complex task performance. It was expected that easy goals would be superior to moderate or impossible goals because the complexity and uncertainty of the task distorts subjects' perceptions of goal difficulty.

An Empirical Investigation of the Impact of Cognitive Complexity and Experience of Programmers, and Program Complexity on Program Comprehension and Modification

Description: The psychological characteristics of programmers are believed to be important determinants of programming productivity. However, little evidence is available to support this contention. This investigation, motivated by the lack of such evidence, was concerned with determining the influence of the programmer's cognitive complexity (differentiation and integration) and experience on comprehending and modifying programs of different levels of complexity. Data were collected from ninty-three graduate and undergraduate students in a classroom experimental setting. In the first phase of the experiment, a background questionnaire was administered in order to collect experience and other demographic information. Also, a domain-specific Role Construct Repertory (REP) Test was administered to collect cognitive complexity information. In the second phase, the subjects were randomly assigned to either the program comprehension group or to the program modification group. Both groups used two COBOL programs of differing levels of complexity to do comprehension and modification exercises. Three sets of hypotheses were tested. The first set of hypotheses was designed to evaluate the direction and strength of the relationship between cognitive complexity and program comprehension and modification. The second set of hypotheses was designed to evaluate the combined influence of cognitive complexity and program complexity on the comprehension and modification of the programs. The third set of hypotheses was designed to evaluate the moderating effect of experience on the relationship of cognitive complexity to program comprehension and modification. Cognitive integration was found to have a significant and positive nonlinear relationship only with the relatively complex program modification scores. The subjects who were ranked high in cognitive integration performed better than those ranked low in modifying the relatively complex program; but they performed the same in modifying the relatively simple program. Cognitive differentiation was found to have no significant relationship with either comprehension scores or modification scores. Experience of the subjects did ...

An empirical investigation of the influence of age, gender, and occupational level on stress perceptions, job satisfaction, organizational commitment, and turnover.

Description: This study investigated relationships of age, gender, and supervisor level with job satisfaction, organizational commitment, stress perception, and turnover intention. The demographics were hypothesized to moderate the stress-satisfaction and commitment-turnover relationships. Hypotheses were tested using both parametric and non-parametric bootstrap methods. Subjects were taken from a national survey of 2,663 public sector IT workers. Missing data were imputed using NORM software. Ordinary least squares (OLS) regression indicated a significant direct effect from all main variables and covariates, except for age on turnover intent. No mediating effects were found. Age-Commitment was the only significant higher order modifier relationship, although Gender-Commitment explained substantial variance. LMG statistic results enabled the predictors to be rank ordered with confidence intervals. Best subset bootstrap regression explored all possible predictor orders to confirm which model explained the most variance. The original model and predictor sequence were confirmed. The bootstrap AIC statistic provided a model which maximized explained variance while optimizing parsimony. Since only age had a mediating effect, Hypotheses 1 and 2 were not supported. All other hypotheses were partially confirmed.

An Empirical Investigation of the Lobbying Influence of Large Corporations on Selected FASB Standards

Description: The Financial Accounting Standards Board is a private sector rule making body. Congressional inquiries have questioned whether the setting of accountin standards should remain in the private sector. Congressional critics have charged that the FASB has been captured by special interests and recommended that a governmental agency assume responsibility for standard setting. Specifically, critics charge that large corporations capture the Big Eight accounting firms who, in turn, have captured the FASB. Previous capture studies have concluded that the standard setting process is pluralistic and that the FASB has not been captured. The studies have focused on the influence of the Big Eight to determine if the FASB has been captured. They assume if standards do not reflect the expressed preferences of the Big Eight, then Congressional criticisms are invalid. The studies also assume a unidirectional influence between participants in the process and have ignored the intensity of preferences of the respondents.The purpose of this study is to provide a theoretical framework to specify selection of standards that would be expected to be subject to capture. This framework also recognizes the duo-directional nature of influence. The allegations of capture were tested using the standards selected in accordance with the theoretical framework. The following hypotheses were tested. HO_1 There is no positive statistically significant relationship between clients' preferences and an accounting firm's support for an outcome. HO_2 There is no positive statistically significant relationship between the preferences of large corporations and standards enacted by the FASB. HO_3 There is no positive statistically significant relationship between the preferences of the Big Eight firms and the standards enacted by the FASB. These hypotheses were tested for each Big Eight accounting firms and for each standard. A logist procedure was employed. The results of the tests, with three exceptions, indicate that any relationships that occurred ...
