A Model for the Efficient Investment of Temporary Funds by Corporate Money Managers

Description: In this study seventeen various relationships between yields of three-month, six-month, and twelve-month maturity negotiable CD's and U.S. Government T-Bills were analyzed to find a leading indicator of short-term interest rates. Each of the seventeen relationships was tested for correlation with actual three-, six-, and twelve-month yields from zero to twenty-six weeks in the future. Only one relationship was found to be significant as a leading indicator. This was the twelve-month yield minus the six-month yield adjusted for scale and accumulated where the result was positive. This indicator (variable nineteen in the study) was further tested for usefulness as a trend indicator by transforming it into a function consisting of +1 (when its slope was positive), 0 (when its slope was zero), and -1 (when its slope was negative). Stage II of the study consisted of constructing a computer-aided model employing variable nineteen as a forecasting device. The model accepts a week-by-week minimum cash balance forecast, and the past thirteen weeks' yields of three-, six-, and twelve-month CD's as input. The output of the model consists of a cash time availability schedule, a numerical listing of variable nineteen values, the thirteen-week history of three-, six-, and twelve-month CD yields, a plot of variable nineteen for the next thirteen weeks, and a suggested investment strategy for cash available for investment in the current period.

Validation and Investigation of the Four Aspects of Cycle Regression: A New Algorithm for Extracting Cycles

Description: The cycle regression analysis algorithm is the most recent addition to a group of techniques developed to detect "hidden periodicities." This dissertation investigates four major aspects of the algorithm. The objectives of this research are 1. To develop an objective method of obtaining an initial estimate of the cycle period? the present procedure of obtaining this estimate involves considerable subjective judgment; 2. To validate the algorithm's success in extracting cycles from multi-cylical data; 3. To determine if a consistent relationship exists among the smallest amplitude, the error standard deviation, and the number of replications of a cycle contained in the data; 4. To investigate the behavior of the algorithm in the predictions of major drops.

The Origination and Evolution of Double-Entry Bookkeeping to 1440

Description: The problem of this investigation is that of determining how double entry bookkeeping originated and evolved during the thirteenth, fourteenth and fifteenth century in mediaeval Italy and its influence on capital formation. The methodology of this study included the use of both primary and secondary sources of information. Great reliance was placed upon a direct examination of original documents found mainly in the State Archives of Genoa, Florence, Milan and Venice. Because this is basically a historical research, particular emphasis was given to the study and criticism of economic, political and religious conditions that most likely had a considerable influence on the creation and evolution of bookkeeping techniques and methods.

An Investigation into the Determinants of Performance in the Dual-Fund Industry in the United States from Inception Through 1973

Description: This research is a systematic, in depth empirical test of the strong form of the efficient market hypothesis (EMH) using the dual-fund industry as the research subject. Unlike most strong-form EMH research, this study deals with a small, homogeneous sector of the investment company industry with a comparable origin date. To obtain homogeneity of the research subjects, the sample size is necessarily small (7), thus, making it difficult to find statistically significant results. In general, portfolio performance is negatively correlated with variability in measures of portfolio characteristics such as the major mix, common stock categories, portfolio turnover, etc. The better-performing dual funds were more consistently managed while the lower-performing companies had significant and sometimes frequent changes in portfolio policies. In line with the efficient market hypothesis, "passive" management, i.e., low turnover, few changes in major mix or common stock composition, shows better results in the dual-fund industry from inception through 1973.

A Computer Simulation of an International Marketing Environment

Description: The purpose of this study is to develop a simulator which would bridge the gap between theory and reality for the student of international marketing. The simulator developed is a computerized business game entitled "The International Marketing Simulator." The International Marketing Simulator contains a description of the model, player's manual, and scenario section, Incorporated in this section is information on how to input decisions into the computer game. The International Marketing Simulator also contains information on the functioning of the International Marketing Simulator. Some of the functions discussed were the demand function, production function, and the promotion function. When the demand function was discussed it was noted that price and promotion were interrelated. The last part of the International Marketing Simulator is a detailed story of each of six foreign countries which are used in the International Marketing Simulator. This section is called the scenario section since each country has a story about it which "sets the stage" for the computer game. There were four parts to the verification process of the International Marketing Simulator. The four parts were (1) making trial program runs an an IBM 360 computer, (2) verifying the logic of the model of the International Marketing Simulator, (3) students participating in making trial runs on the International Marketing Simulator, (4) conducting a before-after study with a control group.

An Empirical Investigation of the Effects of Individual Differences and Data Models on the Ease-of-Use of Database Query Facilties by Casual Users

Description: The problem motivating this study is that database query facilities are not effectively meeting the needs of casual users. A solution to this problem is especially important due to the increasing number of potential casual users. There is considerable controversy revolving around the question of which elements and/or which combination of elements within the casual users' environment are necessary to provide an effective man/machine interface. The purpose of the study is to extend the basic knowledge relating to the effect of using different data models, the effect of cognitive style differences, and the interaction effects of these two independent variables on casual users' performance and confidence in writing database queries. The data models being investigated are the relational, hierarchical, and network models. The cognitive style classifications used are two of the Jungian dimensions, Sensing/Intuition and Thinking/Feeling.

The Organizational Consequences of Information Deployment

Description: This study investigates the influence that increasing end user autonomy has on organizational data models. The independence offered by microcomputer technology offers users increasing independence in their information-handling activities. As independence increases, uniformity of data models across the organization is theorized to diminish. The problem motivating this study is the potential for improper allocation of resources that may result from a misinterpretation of organizational data. This study suggests that the expanding use of microcomputers in the business setting will contribute to diversity of data models. This may eventually lead to confusion and even lack of confidence in the information produced.

The Separation of Rehabilitation from Production Costs in the Vocational Rehabilitation Workshop

Description: The problem with which this study is concerned is the separation of rehabilitation from production costs in vocational rehabilitation workshops. Within workshops there are those functions and tasks—testing, counseling, and the administration thereof—which clearly are rehabilitative. The costs of these activities, therefore, are solely rehabilitation costs. In the production area of workshop operations, however, where production and rehabilitation efforts are intertwined, two kinds of costs are incurred simultaneously: (l) rehabilitation or training costs and (2) production costs. As yet, no generally accepted procedures exist for separating these joint costs.

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 ...

A New Gravitational Approach to Least Transportation Cost Warehouse Location

Description: The purpose of this study is to examine single facility warehouse location models. The need for such a study is primarily two-fold. First, single facility warehouse location models which determine an alleged optimum location through a coordinate system have been developed. Secondly, the need for additional research is necessary because the approaches involving linear programming, simulation, or heuristic programming do not by definition generate an optimal location.

An Empirical Examination of the Relationship Between Audit Committees and the Displacement of Accounting Firms

Description: The purpose of this research was to empirically examine the relationship between audit committees and the changing of independent accounting firms, especially those independent auditor changes in which accounting firms are displaced as auditors by accounting firms that are in the larger-sized category. This research involved the testing of two different, but closely related questions. The first research question asks, "Does the existence of an audit committee of a board of directors partially explain a company's decision to change independent accounting firms?" The second research question asks, "Does the existence of an audit committee of a board of directors partially explain a company's decision to change to a larger accounting firm rather than change to an accounting firm of equal or smaller size?" Statistical models were developed for the two research questions using criteria involved in the auditor change decisions as reported in previous research studies. Eight criterion, including the existence of an audit committee, were defined specifically and incorporated into a survey instrument. The survey instrument was circulated to the accounting firms in the Dallas-Fort Worth area. The accounting firms were asked to report certain information regarding their current and previous auditing clients. Data received from the firms were analyzed using multiple regression techniques .

The Role of Workstation-Based Client/Server Systems in Changing Business Processes: a Multiple Case Study

Description: Although several studies question information technology's contribution to productivity, organizations continue to invest in client/server systems (CSSs) particularly as enablers of business process reengineering (BPR). These efforts may be wasted if they do not improve business processes. This study focused on business processes and investigated the role of workstation-based CSSs in changing business processes. A multiple case study of workstation-based CSS databases in three organizations was performed with the proposition that they moderate the relation between managerial action and changes within business processes. The research framework suggested that changes to business processes are achieved by reducing uncertainty. In order to measure change in business processes, this study categorized business process change into: (1) compressing sequential tasks across functions, (2) compressing tasks vertically within the managerial hierarchy, (3) eliminating slack resources, (4) reducing the distance between the point of decision and the point of information or eliminating intermediaries, (5) reconfiguring sequential processes to operate in parallel, and (6) linking parallel activities during the process. Data collected from questionnaires, interviews, and observations from three case studies were used to construct network diagrams, relationship matrices, reachability matrices, and task tables of business processes. The results of this research partially support the proposition that managerial action affects business process change by reducing uncertainty. This research suggests that changes in the use of workstation-based CSSs are related to changes in business processes. However, because ofthe small sample size, no finding was made regarding changes in the strength of that relationship. Therefore, within its limitations, this research (1) partially supports the proposition that CSSs moderate changes in business processes, (2) found that both favorable and unfavorable changes may result from using CSSs, (3) explains how business process change occurs, and (4) suggests new variables for measuring successful BPR.
