The Effect of Increased Cardiorespiratory Fitness on Job Performance and Job Satisfaction (open access)

The Effect of Increased Cardiorespiratory Fitness on Job Performance and Job Satisfaction

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 …

An Empirical Investigation into the Role of the Fundamental Economical Variables in the Determination of the Foreign Exchange Rates of Nine Countries, 1973-1978 (open access)

An Empirical Investigation into the Role of the Fundamental Economical Variables in the Determination of the Foreign Exchange Rates of Nine Countries, 1973-1978

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.

The Establishment of Helicopter Subsystem Design-to-Cost Estimates by Use of Parametric Cost Estimating Models (open access)

The Establishment of Helicopter Subsystem Design-to-Cost Estimates by Use of Parametric Cost Estimating Models

The purpose of this research was to develop parametric Design-to-Cost models for selected major subsystems of certain helicopters. This was accomplished by analyzing the relationships between historical production costs and certain design parameters which are available during the preliminary design phase of the life cycle. Several potential contributions are identified in the areas of academia, government, and industry. Application of the cost models will provide estimates beneficial to the government and DoD by allowing derivation of realistic Design-to-Cost estimates. In addition, companies in the helicopter industry will benefit by using the models for two key purposes: (1) optimizing helicopter design through cost-effective tradeoffs, and (2) justifying a proposal estimate.

The Evaluation and Control of the Changes in Basic Statistics Encountered in Grouped Data (open access)

The Evaluation and Control of the Changes in Basic Statistics Encountered in Grouped Data

This dissertation describes the effect that the construction of frequency tables has on basic statistics computed from those frequency tables. It is directly applicable only to normally distributed data summarized by Sturges' Rule. The purpose of this research was to identify factors tending to bias sample statistics when data are summarized, and thus to allow researchers to avoid such bias. The methodology employed was a large scale simulation where 1000 replications of samples of size n = 2 ᵏ⁻¹ for 2 to 12 were drawn from a normally distributed population with a mean of zero and a standard deviation of one. A FORTRAN IV source listing is included. The report concludes that researchers should avoid the use of statistics computed from frequency tables in cases where raw data are available. Where the use of such statistics is unavoidable, the researchers can eliminate their bias by the use of empirical correction factors provided in the paper. Further research is suggested to determine the effect of summarization of data drawn from various non-normal distributions.

An Index of Interpersonal Communicative Competence and Its Relationship to Selected Supervisory Demographics, Self-Actualization and Leader Behavior in Organizations (open access)

An Index of Interpersonal Communicative Competence and Its Relationship to Selected Supervisory Demographics, Self-Actualization and Leader Behavior in Organizations

The purpose of this study was basically twofold: 1) to develop an evaluative instrument to measure interpersonal communicative competence, and 2) to determine its relationship to three other supervisory variables—demographic characteristics, self-actualization, and leader behavior. Hypotheses testing, via the Pearson correlation coefficient, indicated the following relationships between interpersonal communicative competence (as measured by the IICC) and supervisory demographics, self-actualization (as measured by the POI), and leader behavior (as measured by the SBDQ): 1) The age of the supervisor was negatively related to the IICC at the .001 level of statistical significance. 2) Years of formal education was positively related to the IICC at the .001 level. 3) The sex of the supervisor (females scoring higher) was related to the IICC at the .01 level. 4) No significant relationship existed between years of supervisory experience and the IICC. 5) Six scales of the POI (I, Ex, Fr, S, A, C) were related to the IICC at the .001 level of statistical significance, one scale (Sy) at the .01 level and two scales (Tc, Sa) at the .05 level. Three scales (SAV, Sr, Nc) were not significantly related to the IICC. 6) No significant relationship existed between the IICC and the two …

An Inquiry into Selected Communication Problems Inherent in Financial Statement Certification and Investor/Creditor Response in Light of the Recommendations of the Commission on Auditors' Responsibilities (open access)

An Inquiry into Selected Communication Problems Inherent in Financial Statement Certification and Investor/Creditor Response in Light of the Recommendations of the Commission on Auditors' Responsibilities

Business organizations disclose financial Information to a wide range of audiences through the medium of audited financial statements. Distinct classes of readers come in contact with these statements—each reader possessing varying degrees of financial expertise. Readers as "semantic reactors" develop their own expectations and interpretations of the messages management and the auditor are attempting to convey. In the process, many readers look upon the auditor's report as a "symbol" or seal of approval. The purposes of this study were to assess the role that communication theory plays In the auditor's attestation, to examine the perceived communication effects of the expanded auditor's certificate versus the current auditor's certificate, and to recommend ways in which communication problems can be dealt with more effectively. It was concluded that a communication problem does exist in relation to the auditor's report, and communication theory can play a distinctive role in reducing the magnitude of this problem. The profession should continue to seek answers as to the proper role of the auditor and management in relation to audited financial statements, as well as to settle the question concerning whom the statements are intended to serve.

A Model for Optimal Interspousal Transfers in Estate Planning (open access)

A Model for Optimal Interspousal Transfers in Estate Planning

The problem with which this study is concerned is that of determining the optimal transfer of property from a decedent to his surviving spouse. A secondary problem addressed is whether equity between common law states and community property states in the application of the estate tax provisions has been achieved through the allowance of the marital deduction. From this analysis decision criteria were developed to aid taxpayers and their advisors in determining optimal property transfers to a surviving spouse. Conclusions of the study were the following: (1) The primary concern when formulating an estate plan should be to determine whether any property should be transferred to the surviving spouse. The literature has stressed qualifying transfers for the marital deduction while giving minimal consideration to the wisdom of doing so. This study indicates that in a majority of estates optimal results are obtained by making no transfers to the surviving spouse. (2) Relative after-tax rates of return of the surviving spouse and other beneficiaries are the most important factors in determining optimal transfers to the spouse. This again conflicts with the literature which has emphasized relative estate sizes as the dominant factor. (3) Rates of inflation have minimal influence in determining …

A Study of the Collective Bargaining Process After Issuance of the Certification of Representative and an Analysis of Similarities in Ratified Contracts (open access)

A Study of the Collective Bargaining Process After Issuance of the Certification of Representative and an Analysis of Similarities in Ratified Contracts

This project explored the period immediately following the NLRB certification of the representation election wherein a Certification of Representative was actually issued. The intent was to examine the ultimate effects of the collective bargaining process after a labor organization was recognized as the official bargaining agent for a bargaining unit. The main purpose of this study was to investigate the collective bargaining process between two established dates: (1) the date the union was certified the collective bargaining agent, and (2) the date a collective bargaining agreement, if any, was obtained. Study data and findings were organized and presented by four research hypotheses. Hypothesis 1 (once a collective bargaining agent is certified as the collective bargaining representative by the NLRB, it will negotiate a collective bargaining agreement) was not supported by total elections for both fiscal years combined; however, responses received percentages resulted in a collective bargaining achievement. Hypothesis 2 (there will be no difference in the amount of time required to negotiate and ratify a collective bargaining agreement following a consent election as compared with stipulated consent or directed elections) was not supported by the research responses received. Hypothesis 3 (once a collective bargaining agreement is negotiated and ratified, it …

The Use of Shared Service Arrangements by Member Hospitals of the Dallas Hospital Council (open access)

The Use of Shared Service Arrangements by Member Hospitals of the Dallas Hospital Council

This study was designed to assess the types of shared service arrangements and the degree of commitment as evidenced by the incorporation of policy statements displayed toward the sharing concept evident in the Dallas-Fort Worth hospitals. The purpose of this research, then, was to identify and evaluate present utilization of shared arrangements to establish a base for comparison and recommendations for future participation by the various categories of hospitals. The conclusions derived from the findings include the following: 1. Shared services promise to be a continuing factor in the operation of the health care industry in the future. 2. Governmental influence and regulation will expand into every area of health care. Hospital administrators must take every opportunity to contribute input to the formulation of these regulations. 3. The selection of products or services to be shared must be handled in a systematic manner complete with a control system to assure continued quality levels. 4. Standardization of product specifications is the single largest obstacle to the expansion of the shared service concept. This obstacle can be removed only through the committed involvement of the medical community. 5. The sharing of services, rather than products, appears to have great potential in terms …
