The personality characteristic locus of control internality is widely-accepted as a trait possessed by women entrepreneurs. Recent research also suggests the presence of a coexisting attribute of similar strength, characterized as influence of a significant other. The presence of one personality characteristic implying perception of self-directed capability, together with indication of need for external assistance, poses a theoretical paradox. The study's purpose was to determine the nature and extent of direct and interactive effects which these and related variables had on entrepreneur return on investment. It was hypothesized that dimensions of significant other, as operationalized for this research, would support internality of locus of control and also modify constraining effects of educational and experiential disadvantage which the literature cites as pertinent to women entrepreneurs. This was nonexperimental, exploratory research of correlational cross-sectional design which examined hypothesized variable linkages. A convenience sample from a women's entrepreneur networking group was surveyed. Significant other elements were derived from factor analysis, resulting in four common dimensions. These factors, together with Rotter's Locus of Control instrument scores, reports on levels of education and experience, and hypothesized interactions, were independent variables. Hierarchial multiple regression was used to test a proposed path model. Two interpretable four-factor solutions …

This work collected four years of financial data from an employee-owned firm and a traditionally-owned firm from the same industry. The data were then organized to provide measures of three dimensions of corporate performance: (1) employee turnover, (2) productivity, and (3) profitability. Based upon a review of the literature, employee stock ownership plans (ESOP) are reported to enhance corporate performance after their adoption. Additionally, ESOPs are purported to perform better than traditionally-owned companies. This dissertation developed hypotheses to ascertain whether or not the particular ESOP used in this study conformed to these expectations. The first set of three hypotheses was tested using multiple regression techniques to determine if the ESOP experienced a reduction in turnover, an improvement in productivity, and an increase in profitability following its conversion to employee-ownership. The results of the regressions found that there was no incremental significance. There was no improvement noted in the performance of the ESOP firm. Another component of this investigation was to determine whether improvements in corporate performance were temporary or permanent phenomena. This portion of the research was rendered superfluous when no improvements were available for analysis. The final question that was examined was whether the ESOP would demonstrate better performance …

This study was concerned with characteristics of the process of reaffirmation of accreditation in the Southern region among institutions that completed reaffirmation under the revised _Criteria for Accreditation_ and those that completed reaffirmation under the former _Standards of the College Delegate Assembly._ The institutions that had completed reaffirmation under the new _Criteria_ were identified. A matching group of equivalent institutions which had last completed reaffirmation under the _Standards_ was created. Each group contained 66 institutions. Data were collected using the records of the Commission on Colleges of the Southern Association of Colleges and Schools. Four areas were identified in which the implementation of the _Criteria_ might affect the process of reaffirmation of accreditation: (a) institutional organization for the self-study, (b) visiting committee composition, (c) number of recommendations by visiting committees, and (d) substance of recommendations by visiting committees. A series of nine hypotheses were tested to assess these effects. The process of reaffirmation of accreditation does not appear to have been substantially affected by the implementation of the new _Criteria for Accreditation._ Institutional organization for the self-study appears unaffected by the implementation of the Criteria for most institutions. There appears, however, to be evidence that the _Criteria_ have effected change …

The general purpose of this study is to examine the effects of socialization background and cognitive style on individuals' patterns of behavior. The more specific purpose is to integrate the individual differences factor using the Myers-Briggs Type Indicator with Meadian Theory of Socialization in order to explore the ways in which a group of incarcerated individuals with prior felony and misdemeanor convictions and a group of college students are different regarding their different socialization background and cognitive styles. Data for this study were collected from a university and a county jail in Texas. During the process of data collection, two questionnaires consisting of 117 items were used to measure individual characteristics and elements of socialization background. This study is organized into four different chapters. Chapter I involves a detailed review of related literature, the purpose of the study, stated hypotheses, significance of the study, and limitations. Chapter II discusses methodological procedures and Chapter III presents the findings of the study. The last chapter includes a detailed conclusion and practical implications of the study. The findings in this study indicated that the group of incarcerated individuals and the group of college students are significantly different in terms of their different individual …

Night of Glass is for chamber orchestra with an estimated performance time of 14 minutes. The instrumentation for the work, using one player per part, is Flute (also small glass wind chimes), Oboe (also 1 tuned water crystal), Clarinet in A (also small glass wind chimes), Bassoon (also 1 tuned water crystal), Horn in F (also 1 tuned water crystal), Trumpet in C (also 2 tuned water crystals), Percussion (Vibraphone, Glockenspiel, Chimes, Bell Tree, Hammered Dulcimer, 3 Suspended Cymbals, 1 Large Tam-tam, 4 Roto Toms, 3 Tympani), Piano, 1st Violin, 2nd Violin, Viola, Cello, and Double Bass, While not programmatic, the work is divided into six sections each expressing a predetermined emotional content: fragility, anxiety, solitude, fear, catharsis, and reconciliation. All are emotional contents which are found in the dream-state that is reflected in the work's title. All aspects of Night of Glass (i.e., pitch material, form structure, and structural density) are centered around the unifying factor of emotional projection within each section. The work seeks emotional content through the expansion of composition procedures while being accessible to listeners.

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. …

This dissertation is a descriptive, exploratory examination of professional commitment, organizational commitment, and conflict between those commitments in the internal audit profession. That conflict has been suggested in prior studies as the source of dysfunctional outcomes such as increased role stress, high turnover, decreased job satisfaction, and the exercise of improper judgment leading to audit failures. The descriptive aspect of this study deals with the development of a more comprehensive structural model of the factors and relationships involved in commitment and conflict than has been developed by previous research dealing with accountants. The exploratory aspect deals with the testing and refinement of the developed model utilizing the internal audit profession as the field of examination. The model developed in this study is derived from the synthesis of factors suggested by role theory, the concept of side bets, the cosmopolitan-local construct, and the concept of commitment as a process. This research utilizes a questionnaire administered to 205 practicing internal auditors in order to test 30 hypothesized relationships. Path analysis is used to determine the significant direct relationships between variables with a process of theory trimming being conducted in order to produce more parsimonious structural models. Indirect relationships between significant variables are …

The purpose of this study was to trace the historical development of the American University of Beirut and its educational contributions in Lebanon and the Middle East from 1920 to 1967. Through their activities in the Levant in the early nineteenth century, the American missionaries virtually laid the foundations of the Syrian Protestant College, later known as the American University of Beirut. Though religion was the cornerstone in the founding of the University, under the pressure of the local environment, its secular character was to be substituted for the religious one. The establishment of the University in 1866 marked the beginning of the system of higher education in the Arab world. As the first established institution of higher learning, the University played a significant role in raising the level of literacy throughout the region. Despite the difficult times that the University faced throughout its history, it survived and continued its dedicated mission to serve the people of Lebanon and the entire area. For the University, the first 50 years under Ottoman rule was a period of surviving and maintaining its existence. With the freedom it came to enjoy during the French Mandate and later during independence, the University moved into …

The objective of this study was to examine the relationship between intensity of short-range and medium-range capacity management and effectiveness of manufacturing operations. Data were collected to test the null hypothesis which stated that intensity of short-range and medium-range capacity management does not influence manufacturing effectiveness. Intensity of short-range and medium-range capacity management was indicated by the following variables: (1) production standards; (2) priority determination; (3) delivery dates determination; (4) material requirements planning; (5) routing information; (6) capacity utilization; and (7) backlog measurement. Manufacturing effectiveness was indicated by the following variables: (1) delivery dates performance; (2) lead times; (3) subcontract work; (4) direct labor overtime; (5) direct labor efficiency; (6) plant and equipment utilization; and (7) work in process inventory. The population selected to provide data for this study is the manufacturing firms in the State of Texas with five hundred or more employees. Over 42 percent of the eligible firms responded to a six-page questionnaire. Several multivariate techniques were utilized for data analysis: (1) factor analysis; (2) canonical correlation analysis; (3) bivariate correlation; (4) multiple linear regression; (5) cross-tabulation; and (6) analysis of variance. The results of this research did not adequately support the rejection of the null hypothesis. …

In this paper we consider an existence of a solution for a nonlinear nonmonotone wave equation in [0,π]xR and an existence of a positive solution for a non-positone Dirichlet problem in a bounded subset of R^n.

This documents aims at the identification of the sources of influence upon the styles of selected 20th century Chinese composers. Personal influences are reflected as well as those general influences specific to the different stylistic periods discussed. Most important, however, is the description of the methods by which these composers employ contemporary compositional devices to project musical gestures that are uniquely Chinese: elements of culture which are fundamentally programmatic and intimately related to the lives of the Chinese people. The introduction of Western music and musical instruments to China in the early 17th century and cultural exchanges with Japan served to gradually westernize the musical environment and training. The establishment of decidedly Western schools was accomplished at the beginning of this century, with the founding of Peking University and Shanghai National Conservatory. Music theory was taught, as well as history and composition, but with an emphasis on the practices of the 18th and 19th centuries. Compositions from this period reflect Western techniques from these eras, with some use of the pentatonic scale. In the 1930's, nationalism arose, a mirroring of the 19th-century European nationalistic trends. This philosophical conception has remained essentially unchanged to the present, as composers have aimed to …

The problem of the quadrupole interaction occurring in a vibrating-rotating C₃v symmetric top molecule has been studied in detail. The quadrupole interaction has been treated as another perturbation term to a general frequency expression accounting for the vibrating-rotating interaction of the molecule so that a complete frequency formula is obtained for both interactions, and from which hyperfine spectral components are predicted and measured. The hyperfine transitions in the ground, and v₈=1 and v₈=2 excited vibrational states of the ¹³C isotopes of methyl cyanide have been investigated in the frequency range 17-72 GHz, primarily in the low J transitions (0≤J≤3). The study of the ground state of isotope i3CH3i3CN, and the v₈=1, v₈=2 excited vibrational states for all the isotopes have been conducted here for the first time. A substantial perturbation has been discovered and discussed at the ΔJ=3→4 transitions within the Kl=1 sets in the v₈=1 mode for isotopes ¹³CH₃CN and CH₃¹³CN. A total of 716 hyperfine transitions have been assigned from measurements, only 7 of which have been measured previously. A total of 84 molecular constants have been reported; 70 of these constants are derived for the first time from microwave data.

The purpose of this study was to determine and compare the academic advising needs of students as perceived by students and faculty advisors through faculty advising functions in the six teachers' colleges in Bangkok, Thailand. Fifteen faculty advising functions were included in a questionnaire validated by a panel of three judges. The questionnaires were distributed to students and faculty advisors in the six teachers' colleges by two selected research assistants. A total of 180 faculty advisors and 540 junior and senior teacher training students at the six teachers' colleges in Bangkok, Thailand, were selected using stratified random sampling. The usable and complete questionnaires received included 109 from faculty advisors (60.56 per cent) and 350 from students (64.81 per cent). The t-test, the Kendall's Coefficient of Concordance W, and the Spearman's Coefficient of Rank Correlation were employed to determine and compare the differences, the agreements, and the relationships of academic advising needs of students as perceived by students and faculty advisors, respectively. Analyses of the data revealed that students and faculty advisors in the six teachers' colleges in Bangkok, Thailand, perceived a mismatch between student advising needs now being fulfilled and student advising needs that should be fulfilled. Apparently, the academic …

This dissertation is a study of the dynamics of one-dimensional unimodal maps and is mainly concerned with those maps which are trapezoidal. The trapezoidal function, f_e, is defined for eΣ(0,1/2) by f_e(x)=x/e for xΣ[0,e], f_e(x)=1 for xΣ(e,1-e), and f_e(x)=(1-x)/e for xΣ[1-e,1]. We study the symbolic dynamics of the kneading sequences and relate them to the analytic dynamics of these maps. Chapter one is an overview of the present theory of Metropolis, Stein, and Stein (MSS). In Chapter two a formula is given that counts the number of MSS sequences of length n. Next, the number of distinct primitive colorings of n beads with two colors, as counted by Gilbert and Riordan, is shown to equal the number of MSS sequences of length n. An algorithm is given that produces a bisection between these two quantities for each n. Lastly, the number of negative orbits of size n for the function f(z)=z^2-2, as counted by P.J. Myrberg, is shown to equal the number of MSS sequences of length n. For an MSS sequence P, let H_ϖ(P) be the unique common extension of the harmonics of P. In Chapter three it is proved that there is exactly one J(P)Σ[0,1] such that the …

This study concerns the characteristics of fund development directors employed in selected homes for the aged. The first purpose of this study is to develop a profile of job functions, through task analysis, among development directors in charitable homes for the aged. The second purpose of this study is to develop a profile of personal characteristics of development directors of charitable homes for the aged based on the following characteristics: age, sex, educational background, experience outside development, membership in community organizations and amount of specific training in fund development. One instrument was used to gather data for the study. It was distributed to a population of 29 development directors in charitable homes for the aged in Arkansas, Louisiana, Oklahoma, New Mexico, and Texas. This population was predetermined by an initial survey form sent to 193 chief executive officers in the five states mentioned above. Twenty-nine reported formalized programs employing a full-time person with at least a part-time involvement in fund development activities. Of the twenty-nine development directors surveyed, fifteen usable instruments were received (52 percent). A program was used for the survey that included crosstabulation of social characteristics, success in fund raising, length of time in position and educational preparation. …

The purpose of the study was to determine if occupational investigation teachers and vocational administrators held similar or differing attitudes toward the occupational investigation courses in relation to the mainstreamed handicapped students they served. The following conclusions were warranted from the findings of the analyses of the data. Findings derived from multiple T tests indicate that occupational investigation teachers perceive all survey item statements concerning Admission, Review, and Dismissal (ARD) meetings and the content of Individual Education Programs (IEPs) as occurring to a significantly lesser degree than do vocational administrators. There is no significant discrepancy in their perceptions toward the current practices of occupational investigation teacher training, student assessment, classroom accessibility, course content, or special education assistance described in the survey items. The results of the multiple T tests indicate that there are no significant differences between the attitudes and perceptions of occupational investigation teachers and vocational administrators in Texas toward the future of any of the conditions reflected in the survey items. Teachers and administrators agree that all of the current conditions reflected by the items should be promoted to a higher degree in the future. The results of the multiple T tests indicate a high degree of significance …

The behavioral characteristics of leaders have been subjects of study for centuries. The scope of these studies has grown to encompass task analysis, follower needs and situational requirements. Current leadership theories consistently recognize the need for a successful leader to adjust behavior to meet the needs of the task, followers and situation. The problem of this research is to define this ability to modify one's behavior, measure it and test its relationship to demographic and job characteristics. The purpose of this study is to evaluate the correlation of individuals" ability to modify their behavior to job function, hierarchy, climate, feedback, satisfaction and their demographic characteristics. The hypotheses held that high ability to modify behavior would correlate positively with job characteristics, climate, feedback and satisfaction and show no correlation to individual demographics. Data were collected through the administration of three research instruments to 138 managers of three business firms. The instruments were the Participant Data Form providing job and demographic characteristics, Descriptive Adjective Questionnaire measuring an individual ability to modify behavior, and Climate and Satisfaction Evaluation Index measuring climate, feedback and satisfaction. Perason's correlation coefficients were calculated to identify possible relationship between the manager's ability to modify behavior, called versatility, and …

Educators who use criterion-referenced measurement to ascertain the current level of performance of an examinee in order that the examinee may be classified as either a master or a nonmaster need to know the accuracy and consistency of their decisions regarding assignment of mastery states. This study examined the sampling distribution characteristics of two reliability indices that use the squared-error agreement function: Livingston's k^2(X,Tx) and Brennan and Kane's M(C). The sampling distribution characteristics of five indices that use the threshold agreement function were also examined: Subkoviak's Pc. Huynh's p and k. and Swaminathan's p and k. These seven methods of calculating reliability were also compared under varying conditions of sample size, test length, and criterion or cutoff score. Computer-generated data provided randomly parallel test forms for N = 2000 cases. From this, 1000 samples were drawn, with replacement, and each of the seven reliability indices was calculated. Descriptive statistics were collected for each sample set and examined for distribution characteristics. In addition, the mean value for each index was compared to the population parameter value of consistent mastery/nonmastery classifications. The results indicated that the sampling distribution characteristics of all seven reliability indices approach normal characteristics with increased sample size. The …

This research examined the influence of psychological temperament and family-of-origin socialization influences on relationship adjustment in marriage. The major goals were to determine: (a) if there was a relationship between the temperament of one mate in the marriage and the temperament of his or her spouse, and (b) if there was a relationship between the marital adjustment scores of a mate relative to either personal temperament or that of his or her spouse. A secondary purpose was to determine if certain family-of-origin socialization experiences influenced adjustment in marriage. One hundred seventy-nine couples (H = 358) completed three test instruments including the Myers-Briggs Type Indicator (Myers, 1962), Dyadic Adjustment Scale (Spanier, 1976), and the Socialization Background Questionnaire (Church, unpublished), along with a demographic questionnaire. The subjects, volunteers from 12 churches in a large metropolitan area, had mean ages of 35.3 and 33.6 years for husbands and wives, respectively, and had been married for an average of 10.1 years. Five hypotheses and two research questions were tested at the .05 level of significance. The results gathered did not support the hypothesis that there was a relationship between temperament type and mate selection. Similarly, no support was evidenced for any specific relationship between …

This study examined the factors related to travel mode choices in the Dallas-Fort Worth Metropolitan Area. Changes in population, life style and economy of the Dallas-Fort Worth region over the last few decades demand a careful re-examination of travel demand tools and methods. The purpose of the study was to provide an understanding of transportation modal choice in the region. Those demographic variables best predicting the choices were identified. The Home Interview Survey, a set of disaggregate data from the 19 84 North Central Texas Council of Governments (NCTCOG) Regional Travel Survey, was analyzed using logistic regression. The major findings of the research indicate that about 97 percent of the travelers in the study area used private cars and 3 percent used public transit. Household income and cars-vans were significant explanatory variables. The impact of household income and number of car-vans available upon an individual's decision for travel mode choice were very important. The number of car-vans available in the household, and age of respondents were significant predictors in travel mode. Household members with incomes of $30,000 to $39,000 and those with incomes of at least $50,000 tended to use more private cars than did other income groups. Also, household …

Excessive nutrient loading of natural and artificial lakes has led, in some systems, to plethoric algal and aquatic macrophyte growth which can result in aesthetic degradation and undesirable tastes and odors. It would be advantageous to have some indication of the potential trophic status of a reservoir before it is filled. An objective of this study was to assess the water quality and nutrient loading potential of the tributaries entering Ray Roberts Lake, a large reservoir located in north central Texas. Samples from a maximum of thirteen sites were collected on the Elm Fork, Trinity River, Isle duBois Creek, and five additional tributaries. Data were also collected during six storms, from atmospheric deposition collectors, and from soil-water microcosms. The relationship between watershed landuse and mean water nutrient concentrations was evaluated. Significant differences will exist between the two major arms of Ray Roberts Lake: Elm Fork, Trinity River and Isle duBois Creek. While the majority of the annual phosphorus and nitrogen load entering both tributaries is coming from overland flow, the proportion is higher in Isle duBois Creek. Point sources in the Elm Fork contribute a larger percentage of the bioavailable phosphorus, which is significantly greater than in Isle duBois Creek. …

Much of the previous research on organizational performance deals with the larger businesses. As such, the owner/managers of small firms and researchers interested in small businesses have had to work with planning models which were not formulated with small businesses in mind. Therefore, the general purpose of this study is to help correct this deficiency and add to the body of knowledge concerning the contributions specific factors make toward increasing the performance of small firms. Specifically, selected managerial personality traits, managerial perceived environmental uncertainty, managerial scanning habits, and managerial goal setting activities are utilized to develop three models. The three models are used to determine the relationship the factors have to each other and the contribution the variables make toward the performance of the firm. The firms included in this study are located in a South Central metropolitan area. The firms have between 2 and 100 employees, sales of less than 3 million dollars, and have been in operation 2 years or longer. This study utilizes regression analysis and path analysis to determine the effects the factors have on each other and their contribution to the firm's performance. The Statistical Package for the Social Sciences (SPSSx) is utilized to run …

It is believed by many researchers that little attention has been given to patients' perceptions of the impact of chronic pain on their lives. In recognition of this need, G. Frank Lawlis, C. Edward McCoy, and David K. Selby developed the Dallas Pain Questionnaire (DPQ) to assess the amount of chronic pain that affects four aspects (daily activities, work-leisure activities, anxiety-depression, and social interest) of the patients' lives. The present study, conducted to validate the DPQ's statistical properties, first reviews the literature addressing the various theories and varieties of pain, its opiates, and the two current approaches to quantify pain. This study included a total of 143 subjects. Clinical subjects were 104 inpatients in the Spinal and Chronic Pain Center at Medical Arts Hospital and 15 chronic pain outpatients released to work. Normal subjects consisted of staffing personnel (n = 13) and flight assistance employees (U = 11)- Both clinical and normal groups completed the DPQ. The Minnesota Multiphasic Personality Inventory (MMPI) was administered only to the clinical population. Results suggest that the DPQ is both externally reliable (stability reliability coefficient of .970) as well as an internally consistent instrument. Two factors emerged from factor structure analysis. Factor one (63.2% …
