Information systems (IS) are indelibly linked to the global economy and are indispensable to society and organizations. Despite the decisive function of IS in organizations today, IS development problems continue to plague organizations. The failure to get the system requirements right is considered to be one of the primary, if not the most significant, reasons for this high IS failure rate. Getting requirements right is most notably identified with Frederick Brooks' contention that requirements are the essence of what IT professionals do, all the rest being accidents or risk management. However, enterprise architecture (EA) may also provide the discipline to bridge the gap between effective requirements, organizational objectives, and the actual IS implementations. The intent of this research is to examine the relationship between IS development capabilities and requirements analysis and design capabilities within the context of enterprise architecture. To accomplish this, a survey of IT professionals within the Society for Information Management (SIM) was conducted. Results indicate support for the hypothesized relationship between IS development and requirements capabilities. The hypothesized relationships with the organizational demographics were not supported nor was the hypothesized positive relationship between requirements capabilities and EA perceptions. However, the nature of the relationship of requirements and …

The problem is to determine whether there exists a common body of procedures being followed by labor/management arbitrators in the United States. The agreement to arbitrate grievance disputes is the quid pro quo for an agreement not to strike. Currently some 95 per cent of all United States labor agreements provide for arbitration as the final step in the grievance procedure. Arbitration has increased at a steady pace over the years. The American Arbitration Association reports a 330 per cent increase in the number of cases between 1966 and 1975. A study, by the Federal Mediation and Conciliation Service, has found a 300 per cent increase in cases closed between 1968 and 1978. This increase in the use of arbitration to resolve industrial disputes shows the need to analyze the hearing procedures. The results of a study of this type are useful to all concerned in the labor arbitration process.

One perceived deficiency in the tax system is its unfairness (inequity). One area in which unfairness has been alleged is the favoritism shown toward homeowners. The focus of this study was on the effects of homeowner preferences on the Federal tax system. The overall impact of homeowner preferences can be said to produce three major results—loss of revenue, reduction in horizontal equity, and reduction in vertical equity.

The step transaction doctrine is one of the judicial doctrines used by the courts to interpret tax law. The doctrine requires that a series of transactions be treated as a single transaction if the transactions share a single, integrated purpose. Many authors believe there is a great deal of uncertainty as to when the doctrine will be applied. Uncertainty and inconsistency in the application of tax law add to the complexity of the law. One of the most complex areas of tax law is Subchapter C of the Internal Revenue Code, which governs corporate formations, redemptions, liquidations, distributions, and reorganizations. The purpose of this study was to determine if the step transaction doctrine is being consistently applied by the Tax Court and what variables affect the judges' decision in these cases. Hierarchical logit analysis was used to derive a full model and two restricted models. The full model was used to determine the predictive power of the variables that were identified and to explain the extent to which the individual variables affect the judges' decisions. One restricted model was used to test temporal stability. The other was used to test consistency when different issues of tax law are involved. The …

This study analyzes the impact of the political changes on labor unions in Egypt in the period from 1960 to 1967. In 1960-1961 Egypt became a socialist country with one political party, the Arab Socialist Union. As a result of that development in the political arena, a wave of socialist laws were introduced by the government, affecting not only the labor unions' traditional functions, but also the industrial relations system in general. The study came to the following conclusions. 1. The role of the labor unions in the industrial relations system and especially in formulating the socialist laws was minimized in Egypt in the 1960-1967 period. 2. From an economic point of view, the socialist laws in the 1960-1967 period had restrained economic development process by reducing savings, not supplying the economy with skilled productive workers, causing inflation, and the wage structure did not work as an incentive system to stimulate productivity. 3. The socialist laws did not achieve any of their expected objectives partly because no one except the government was involved in these laws' formulation and implementation. 4. Except for the small increase in wages, the average worker did not achieve any tangible benefits that could improve his …

The purpose of the research was to test Walker's assertion that the human resource planning process of an organization is influenced by selected organizational characteristics, and to investigate Walker s typology for implementing and evaluating human resource planning systems. Chapter I introduces the research topic and provides a justification for the study. Chapter II describes the methodology and presents the findings. Chapter III analyzes the findings. The final chapter summarizes the findings and offers conclusions drawn from the research.

The objective of this research is the investigation of the patterns of information growth to test whether there has been an "information explosion." To tackle the main problem, there are three issues which need to be addressed: (1) the concept of information dimensionality; (2) determination of common parameters to measure the amount of information within each dimension; and (3) a working definition of "explosiveness. "

This research applies stochastic decision tree analytical techniques to a decision of the type a small community may face when choosing a solid waste disposal system from among several alternatives. Specifically targeted are those situations in which a community finds itself (1) lying at or near the boundary of a central planning area, (2) in a position to exercise one of several disposal options, and (3) has access to the data base on solid waste which has been systematically developed by a central planning agency. The options available may or may not be optimal in terms of total cost, either to the community or to adjacent communities which participate in centrally coordinated or jointly organized activities. The study suggests that stochastic simulation models, drawing upon a data base developed by central planning agencies in cases where local data are inadequate or not available, can be useful in evaluating disposal alternatives at the community level. Further, the decision tree can be usefully employed to communicate results of the analysis. Some important areas of further research on the small community disposal system selection problem are noted.

The purpose of this research is to study and improve decision accuracy in the real world. Spot price prediction of petroleum products, in a budgeting context, is the task chosen to study prediction accuracy. Prediction accuracy of executives in a multinational oil company is examined. The Brunswik Lens Model framework is used to evaluate prediction accuracy. Predictions of the individuals, the composite group (mathematical average of the individuals), the interacting group, and the environmental model were compared. Predictions of the individuals were obtained through a laboratory experiment in which experts were used as subjects. The subjects were required to make spot price predictions for two petroleum products. Eight predictor variables that were actually used by the subjects in real-world predictions were elicited through an interview process. Data for a 15 month period were used to construct 31 cases for each of the two products. Prediction accuracy was evaluated by comparing predictions with the actual spot prices. Predictions of the composite group were obtained by averaging the predictions of the individuals. Interacting group predictions were obtained ex post from the company's records. The study found the interacting group to be the least accurate. The implication of this finding is that even …

The problem of this investigation was to make an exploratory examination of the distribution practices of apparel manufacturers as perceived by apparel retailers. Specifically, the purposes of this study were to identify those areas of perceived conflict between women's apparel retailers and apparel manufacturers from the viewpoint of the retailer, determine if there was a relationship between select retailer variables and the quality of service that retailers perceived apparel manufacturers were giving, determine whether some merchandise classifications were perceived by retailers to be greater problem areas than other merchandise classifications, to determine factors contributing to the enhancement of perceived conflict within apparel marketing channels, and to suggest remedies that would improve apparel channel relationships. The report concluded with the presentation of an apparel retailer expectation model and suggestions for additional research.

This study compared the results of his chi square text of independence and the corrected chi square statistic against Fisher's exact probability test (the hypergeometric distribution) in contection with sampling from a finite population. Data were collected by advancing the minimum call size from zero to a maximum which resulted in a tail area probability of 20 percent for sample sizes from 10 to 100 by varying increments. Analysis of the data supported the rejection of the null hypotheses regarding the general rule-of-thumb guidelines concerning sample size, minimum cell expected frequency and the continuity correction factor. it was discovered that the computation using Yates' correction factor resulted in values which were so overly conservative (i.e. tail area porobabilities that were 20 to 50 percent higher than Fisher's exact test) that conclusions drawn from this calculation might prove to be inaccurate. Accordingly, a new correction factor was proposed which eliminated much of this discrepancy. Its performance was equally consistent with that of the uncorrected chi square statistic and at times, even better.

Much has been written during the past decade to explain the relationship between financial and operating leverage and stock-price volatility. However, the relationship between combined leverage and stock-price volatility has yet to be fully explored. Mandelker and Rhee's (MR) recent study uses both operating and financial leverage in a regression (equivalent to the traditional total leverage—DTL) and shows that both types of leverage are positively associated with common stock betas. Huffman recently demonstrated that there are interactions between operating leverage and financial leverage. Therefore, MR's model could be oversimplified. This study examines the relationship between firms' combined leverage and their stock-price volatility. The study also examines industry and industry growth to see if the relationship is influenced by these factors. The question is whether DOCL is a better risk measure than DTL and whether there is an interaction between operating and financial leverage. The inferences that can be drawn from the study's results are as follows: (a) Stock risk is a function of combined leverage; (b) Industry significantly influences the relationship between stock risk and DOCL; (c) High growth increases the relationship between stock risk and DOCL; (d) Combined leverage (DOCL) is a better risk measure than total leverage (DTL). …

This study is designed to examine comparative advertising as a viable advertising strategy in today's competitive business environment. Frequency and use of comparisons by the selected key industries and advertising agencies are investigated. Analysis is conducted to determine similarities and differences between firms who elect or avoid comparative advertising. Based on an analysis of the findings, certain conclusions are presented. The industry leader is not likely to use comparative advertising in most industries. Firms that are fourth or smaller in market share are most likely to use comparisons. However, the smallest firms, in terms of dollar sales volume, are least likely to use comparative advertising.

This study compared the results for McNemar's test, the t test for related measures, and the chi-square test of independence as cell sized varied in a two-by-two frequency table. In this study. the probability results for McNemar's rest, the t test for related measures, and the chi-square test of independence were compared for 13,310 different combinations of cell sizes in a two-by-two design. Several conclusions were reached: With very few exceptions, the t test for related measures and McNemar's test yielded probability results within .002 of each other. The chi-square test seemed to equal the other two tests consistently only when low probabilities less than or equal to .001 were attained. It is recommended that the researcher consider using the t test for related measures as a viable option for McNemar's test except when the researcher is certain he/she is only interested in 'changes'. The chi-square test of independence not only tests a different hypothesis than McNemar's test, but it often yields greatly differing results from McNemar's test.

The purpose of this research was to determine if differences exist between the young/old (55-74) and the old/old (75+) regarding external search behavior and the importance of information sources.

In this study, the possibility that money demand of one country might be affected by macroeconomic activities of other countries is investigated. We use the seemingly unrelated regression (SUR) technique, which takes into account all covariances between residuals of country-specific money demand equations. Efficiency of estimates using the SUR technique is enhanced because it uses information contained in the contemporaneous correlation of the error terms. The hypothesis of economic interdependence is tested. A proxy for foreign influence, deviation from interest rate parity (DIRP), is tested for significance in the money demand function.

A non-experimental, descriptive study was conducted to examine the criteria by which ad hoc labor arbitrators are selected in the petroleum refining industry. Three factors — arbitrator background, recognition, and arbitration practice — were examined to determine their relative importance to advocates selecting ad hoc labor arbitrators. The population of the study consisted of management and labor union advocates in the petroleum refining industry who routinely select ad hoc labor arbitrators. Participating management and union advocates completed a questionnaire used to gather respondents' evaluations of criteria considered in the selection of ad hoc arbitrators. Responses to statements designed for measuring relative importance of the criteria considered were recorded. Descriptive statistics, discriminant analysis, and tests of significance were used in the treatment of the data.

This study is intended, first, to describe and analyze the channels of distribution for food products in the State of Kuwait, second, to pinpoint the problems that exist in the food-distribution system, and, third, to make specific recommendations for the alleviation of the problems. Consistent with the objectives of the study and based on the description and analysis of the food-distribution system in the country, it is concluded in the study that Kuwait depends on imports for virtually all of its food; the government plays a major role in the food-distribution system; and the majority of food wholesaling and retailing establishments are small, inefficient, and lack modern marketing and physical distribution techniques. Product shortages and rising food prices plague the food-distribution system in the country. Also, the findings indicate that consumers in Kuwait are generally ignorant and uninformed in the areas of food nutrition and food shopping, and the lack of standardization and grading of food products makes the shopping task of the consumer more difficult.

The area of performance appraisal of the handicapped individual is a relatively uncharted domain. Previous studies have tended to either lump categories of handicaps together or to concentrate their performance appraisal on simplistic performance criteria. This dissertation focused upon the performance of a group of physically impaired workers and their non-impaired co-workers. Central to this research endeavor was a comparison of the aggregate performances of both groups of workers through the use of parametric factor and discriminant techniques as well as the non-parametric sign test.

In this study twenty-two commercial real estate salespeople were randomly assigned to one of four experimental conditions: (1) pretest, training, posttest; (2) pretest, no training, posttest; (3) no pretest, training, posttest; (4) no pretest, no training, posttest. The training groups participated in a monitored aerobics training program designed by the Institute for Aerobics Research, Dallas, Texas. In conclusion, it appears that an improvement in employee cardiorespiratory fitness does not necessarily lead to an improvement in job satisfaction or job performance. It is important to note, however, several possible explanations for these results. First, the pretest scores for the Job Descriptive Index were already quite high indicating there was not much room for improvement on posttest scores. Secondly, with regard to performance scores the; small number of subjects may have contributed to the lack of statistical significance. The study had a 46 percent subject loss rate. Thirdly, it would have been more useful to have had subjects who earned approximately the same amount or, at least, did not have the enormous differences in earnings found in this study. Finally, it is suggested that commissions be watched for more than one sales cycle. By incorporating these changes, future studies will have a …

This study examined a segment of the homeless population who participated in a jobs training program. The research investigated the effect of socioeconomic status, self-esteem, and locus of control on the clients in getting and keeping jobs. The training was a comprehensive 36-day treatment dealing with three major areas: (a) how to get a job, (b) how to keep a job, and (c) how to develop life-coping skills. A quasi-experimental research design was used for testing by t-tests, two-by-two repeated-measured anova, chi-square tests, and regression analysis. The findings showed that high socioeconomic status clients demonstrated higher self-esteem and internal locus of control than low socioeconomic status clients at the start of the treatment. The treatment had a significant effect on both groups with an increase in self-esteem and internal locus of control and a decrease in both external locus of control dimensions of powerful others and chance. The treatment had a greater effect on the low socioeconomic status clients than on the high socioeconomic status clients on increases in self-esteem and locus of control—internal. Both groups were successful in finding jobs, with 79% for high socioeconomic status clients and 74% for low socioeconomic status clients having jobs at the end …

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 …

This empirical study is concerned with whether the oil and gas reserve value data reported by petroleum producers have been utilized by investors. Reporting reserve value data based on a present value approach is the initial step toward the development of the Securities and Exchange Commission's new accounting method called "Reserve Recognition Accounting" (RRA) for oil and gas producers. Experimentation with this new accounting concept in the oil and gas industry has been adopted as a tentative resolution of the long-standing controversy over valuation of oil and gas reserves and the measure of income from oil and gas exploration. Evidence gathered in this research will be valuable to the SEC in its efforts to assess the usefulness of RRA. This dissertation assumes capital market efficiency and address two specific questions. First, do investors behave as if the reported end-of-year reserve value data are effective signals for pricing securities of oil and gas producers? Second, has the SEC-mandated reserve value disclosures induced any response in the capital market? Two research designs were employed to permit extensive investigation of these two questions.

This dissertation examines the role of the fundamental economic variables (price levels, interest rates, and income levels) in the determination of foreign exchange rates during the period 1973-1978. Purchasing power parity, the International Fisher Effect, and the relationship of exchange rates with income levels through the marginal propensity to import were integrated, as suggested by the literature, and a fairly reasonable specification of a model for exchange rate determination was measured. The results of speculation tests indicate destabilizing results for some currencies and stabilizing results for the others; the coefficient of expectation tests, however, lend support to the destabilizing hypothesis. The conclusion of the research, therefore, is that the exchange rates of the major industrial countries which are of prime importance to the international financier and investor, and to the student of international finance and trade, are primarily determined, not by the fundamental economic variables, but by speculative forces which are believed to be of a destabilizing nature.
