Outliers and Regression Models
The mitigation of outliers serves to increase the strength of a relationship between variables. This study defined outliers in three different ways and used five regression procedures to describe the effects of outliers on 50 data sets. This study also examined the relationship among the shape of the distribution, skewness, and outliers.
The Disfigured Muse : Supreme Readers in the Poetry of Wallace Stevens
In "Discourse in the Novel," Mikhail Bakhtin tells us that "Every discourse presupposes a special conception of the listener, of his apperceptive background and the degree of his responsiveness." My study of Wallace Stevens's poetry examines Stevens's "conception of the listener"—in the form of his intratextual readers, their responsiveness, and the shapes that responsiveness takes—and attempts to formulate out of that examination Stevens's theory of reading embodied in his canon of poems.
Solution Studies of the Structures and Stability of Mixed Lithium Alkoxide/Alkvllithium Aggregates
New one- and two-dimensional NMR techniques were used to elucidate the solution structures of these complex mixtures. The system, lithium tert-butoxide/tert-butyllithium, was studied as a model system with O/Li ratios varying from 0/1 to 1/1. It was found that at low O/Li ratios, a single mixed tetrameric aggregate was formed. At higher O/Li ratios, mixed hexameric species were formed. Two other systems, lithium isopropoxide/iso-propyllithium and lithium n-propoxide/n-propyllithium were also studied at low O/Li ratios.
A Comparison of the Desirability and Feasibility of Accountability Measures as Perceived by Public School Administrators and Teachers
This study had three main purposes. The first was to determine the perceptions of public school administrators toward desirability and toward feasibility of accountability items. The second was to determine the perceptions of public school teachers toward desirability and toward feasibility of accountability items. The third was to compare the perceptions of administrators with those of teachers and to indicate areas where they seemed to be in agreement or disagreement.
Sexual Identity Development and Heterosexual Mistrust: An Exploratory Study
The sexual identity development process in gay men was the focus of this study. It was theorized that, as a result of negative experiences with the dominant heterosexual culture, gay men might feel mistrustful of heterosexuals in various settings. A new theoretical construct, that of heterosexual mistrust, was identified and explored. A new scale, the Heterosexual Mistrust Inventory (HMI), was created to measure this construct. Gay male subjects' stage of homosexual identity formation (HIF) was also determined. Results indicated that heterosexual mistrust existed to a significantly stronger degree among gay men than among heterosexual men. Heterosexual mistrust was strongly related to stage of HIF. The various settings in which heterosexual mistrust was found to occur were discussed. Implications for current knowledge about HIF and about cultural belief systems unique to gay men were identified and explored.
A System of Selection and Human Resource Development for Small Retailers of Apparel and Accessories
The study has a twofold purpose. The first is to determine the extent to which organized selection and training practices exist in small apparel and accessory retailing establishments, and the general attitude which small retailers of apparel and accessories express toward the value of selection and training functions. The second is to construct a practical system which can be used in small apparel and accessory retailing establishments.
Using regression analysis to investigate relationships of ASVAB selector composites to end-of-course grades for students in aircraft maintenance training programs in the Air Force
Aircraft maintenance training programs in the Air Force have evolved from an almost exclusively mechanical orientation to one that is largely electronic. The Armed Services Vocational Aptitude Battery (ASVAB) with its four selector composites (Mechanical, Administration, General, and Electronic) has been in use for over 20 years. The mechanical (M) composite score is used to identify those who will be trained in aircraft maintenance.
A Study of the Physical Facilities of Industrial Arts Metalworking Laboratories in the State of Texas
The purposes for conducting this study were to ascertain whether the housing for industrial arts metalworking laboratories was adequate, whether the enrollment of the school showed any correlation with the availability of a metalworking facility, and to what extent the physical facility for metalworking laboratories met current standards.
The Effects of Parental Divorce and Family Conflict on Young Adults Females' Perceptions of Social Support and Adjustment
The purpose of this study was to explore the effects of parental divorce and family conflict during adolescence on young adult females' social support and psychological adjustment. The three areas explored were perceptions of relationship satisfaction and closeness, sources and amount of social support and adjustment. One hundred and forty-one female undergraduates, 53% from families in which their parents are still married and 47% from families in which a parental divorce occurred during adolescence, completed the following measures: the Dyadic Adjustment Scale (Spanier, 1976), the Social Provisions Scale-Source Specific (Cutrona, 1989), the Inventory of Common Problems (Hoffman & Weiss, 1986), the Family Environment Scale (Moos & Moos, 1981), and the Sibling Relationship Questionnaire (Furman & Buhrmester, 1985).
The Relative Desirability of Two Types of Junior College Operation
The problem of this study was to determine whether it is more desirable to operate a two-year college in the Dallas metropolitan area as a county college or to operate a two-year college under the administration of the Dallas Independent School District.
Light Spectra Distributions in Temperate Conifer-Forest Canopy Gaps, Oregon and in Tropical Cloud-Forest Canopy, Venezuela
Light spectra distributions were measured in two different montane forests: temperate and tropical. Spectral light measurements were made in different sized canopy gaps in the conifer forest at H. J. Andrews Experimental Forest in Oregon, USA. Researchers at Oregon State University created these gaps of 20 m, 30 m, and 50 m in diameter. In the tropical cloud forest, spectral light measurements were made in two plots that were permanently established at La Mucuy Parque Nacional in Venezuela, in collaboration with researchers at Universidad de Los Andes. In both studies, spectra and distributions of physiologically active light were analyzed: red, far-red, R/FR ratio, and blue light.
Structural and Photoelectron Emission Properties of Chemical Vapor Deposition Grown Diamond Films
The effects of methane (CH4), diborone (B2H6) and nitrogen (N2) concentrations on the structure and photoelectron emission properties of chemical vapor deposition (CVD) polycrystalline diamond films were studied. The diamond films were grown on single-crystal Si substrates using the hot-tungsten filament CVD technique. Raman spectroscopy and x-ray photoelectron spectroscopy (XPS) were used to characterize the different forms of carbon in the films, and the fraction of sp3 carbon to sp3 plus sp2 carbon at the surface of the films, respectively. Scanning electron microscopy (SEM) was used to characterize the surface morphology of the films. The photoelectron emission properties were determined by measuring the energy distributions of photoemitted electrons using ultraviolet photoelectron spectroscopy (UPS), and by measuring the photoelectric current as a function of incident photon energy.
Autographs 1928 : Four Songs for Soprano and Chamber Ensemble
Autographs 1928: Four Songs for Soprano and Chamber Ensemble is a composition of approximately 16 minutes' duration and is scored for mezzo-soprano, flute, oboe, clarinet, horn in F, viola, violoncello, one keyboardist (piano and celesta), and two percussionists (marimba, xylophone, chimes, timpani, bass drum, temple blocks, triangle, and slapstick). The work consists of four songs and four readings with texts from Walls's maternal grandmother's autograph book. The composition opens with a reading and alternates between readings and songs. The music is intended to reflect the playful, tender and humorous nature of the lyrics.
Effects of a Technology Enriched Learning Environment on Student Development of Higher Order Thinking Skills
The problem for this study was to enhance the development of higher order thinking skills and improve attitudes toward computers for fifth and sixth grade students. The purpose of this study was to determine the impact of a Technology Enriched Classroom on student development of higher order thinking skills and student attitudes toward the computer. A sample of 80 sixth grade and 86 fifth grade students was tested using the Ross Test of Higher Cognitive Processes. The Ross Test was selected because of its stated purpose to judge the effectiveness of curricula or instructional methodology designed to teach the higher-order thinking skills of analysis, synthesis and evaluation as defined by Bloom. The test consisted of 105 items grouped into seven subsections. In addition, the students were surveyed using the Computer Attitude Questionnaire developed by the Texas Center for Educational Technology. The questionnaire assessed sixty-five questions combined to measure eight attitudes.
Design of a Monitoring System for a Plasma Cleaning Machine
Plasma cleaning is the most effective dry process to remove surface contaminates from a SAW (Surface Acoustical Wave) device. Consistent gas pressures, flows, and good electrical connections between the chamber shelves are necessary for the process to function predictably. In addition, operation of the monitoring system must be transparent to the plasma cleaning unit. This thesis describes a simple solution to the complex problem of monitoring a plasma cleaning system. The monitoring system uses the LabVIEW® G programming language and hardware, both products of National Instruments, Inc.®, to monitor critical parameters necessary to achieve a consistent process when cleaning these devices.
Standing in the Gap: Subposts, Minor Posts, and Picket Stations and the Pacification of the Texas Frontier, 1866-1886
This dissertation describes the various military outposts on the Texas frontier between 1866 and 1886. It is arranged geographically, with each chapter covering a major fort or geographical area and the smaller posts associated with it. Official military records and government reports serve as the primary sources of data. In 1866 when the United States Army returned to the defense of Texas after four years of civil war, the state's frontier lay open to depredations from several Indian tribes and from lawless elements in Mexico. The army responded to those attacks by establishing several lines of major forts to protect the various danger areas of the frontier. To extend its control and protection to remote, vulnerable, or strategically important points within its jurisdiction, each major fort established outposts. Two main categories of outposts existed in Texas, subposts and picket stations. Subposts served as permanent scouting camps or guarded strategic points or lines of communication. Picket stations protected outlying locations, such as stage stations, that were particularly vulnerable to attack. Because Indians raiding in Texas usually operated in fairly small groups, garrisons at outposts were similarly small. Company-sized detachments generally garrisoned subposts, and picket stations seldom held more than a dozen troops, often fewer. The army used outposts haphazardly during the first few years after the Civil War. Commanders developed standard tactics for outpost garrisons, but they failed to form a comprehensive strategy incorporating a series of outposts in the plan to pacify a particular region until the late 1870s. At that time, Colonel Benjamin Grierson and others began forming a systematic network of outposts in far West Texas. Concentrating his outposts at the region's few water sources, Grierson was able to use those posts as an effective part of a strategy that eventually brought an end to danger from Apaches …
A Case Study of Interpersonal Influences in a Band Music Setting: Bohumil Makovsky (1878-1950) and His Association with Selected Individuals Involved in Instrumental Music in the State of Oklahoma
The purpose of this study was to investigate the interpersonal influences which Bohumil Makovsky, Director of Bands and Chairman of the Music Department at Oklahoma A&M College from 1915 to 1943, had on his students and peers, as confirmed through the perceptions of selected individuals, and to determine what personal characteristics and means he drew upon to induce changes in his students and peers.

The Effects of Employee Health Promotion Practices of Texas Public School Districts on Costs for Absenteeism, Health Care Premiums, Health Care Claims, and Workers' Compensation Claims
This study examined whether or not it is in the financial best interest of public school districts, as employers, to promote the health of its employees.
Job Satisfaction Among Women Accounting Educators
A national survey was conducted to investigate job satisfaction among women accounting educators at four-year college and universities in the United States. The purpose of the study was to determine if differences existed among women accounting educators at research, doctoral, master's, and baccalaureate institutions in three areas relating to job satisfaction: levels of job satisfaction, individual sources of job satisfaction, and structural sources of job satisfaction. Also, the relationships among these three areas of job satisfaction were examined. A stratified random sample of 755 women accounting educators was selected from the population of 1,519 women. A mailed questionnaire was used to collect data. A total of 495 (66%) questionnaires were returned. Women accounting educators expressed satisfaction with co-workers, supervision, and work. They were neutral regarding satisfaction with pay and dissatisfied with promotion opportunities. A difference was detected between satisfaction with pay and type of institution. Differences were found between individual sources of job satisfaction and type of institution. The differences were attributable to education level and the personality characteristics of conscientiousness and openness. Differences were detected between structural sources of job satisfaction and type of institution. Academic rank, salary, tenure, institutional resources, and job functions accounted for the differences. Significant relationships were found between individual and structural sources of job satisfaction and levels ofjob satisfaction. Satisfaction with co-workers was related to agreeableness, conscientiousness, neuroticism, institutional resources, mentoring, and time spent on research. Satisfaction with pay was related to neuroticism, salary, academic rank, and institutional resources. Satisfaction with promotion opportunities was related to agreeableness, salary, tenure, institutional resources, mentoring, networking, other job functions, and type of institution. Satisfaction with supervision was related to personal roles, agreeableness, salary, institutional resources, mentoring, research, and advising students. Satisfaction with work was related to marital status, personal roles, agreeableness, neuroticism, institutional resources, and mentoring. It …
An Assessment of Employee Satisfaction within a Major Unit of a Worldwide Hotel and Resort Management Company
The purpose of this study was to assess the satisfaction level of 240 employees of a single hotel property. The questionnaire, administered by the Corporate Director of Training, determined if a significant difference exists between overall satisfaction and individual departmental satisfaction regarding 11 dimensions: customer satisfaction, employee involvement/teamwork, work environment, training/development/evaluation, communication, compensation/benefits, supervision, resources, planning/goal setting, general, and departmental interaction. Percentages and t tests were used to analyze the data. Results of the study will help management recommend courses of action needed to address identified problem areas.
Harmonic and Contrapuntal Techniques in the Late Keyboard Works of Cesar Franck
This study examines the five late keyboard works of Cesar Franck: the Prelude, Chorale, and Fugue and the Prelude. Aria, and Finale for piano, and the three organ chorales. The study focuses on harmonic and contrapuntal techniques and their interrelationships, placing the discussion in the context of an analysis of the whole piece. The primary goal is to identify the salient characteristics of each piece; a secondary goal is to identify common harmonic and contrapuntal aspects of Franck's style.
Myths and Movies: a Mythographical Methodology of Motion Picture Analysis
Over the past decade, cinema studies scholars have begun to recognize the value of mythographical methodologies for motion picture analysis; however, most of the scholarly research in this field has focused either on mythic archetypal images or on monomythic narrative structure, rather than combining the two approaches into a unified theory. This essay addresses the problem by proposing a mythographical methodology of motion picture analysis based on Carl Jung's theory of archetypal images and Joseph Campbell's theories concerning the monomythic structure of heroic narratives. Combining the two approaches of myth interpretation results in a more comprehensive methodology for interpreting the mythic elements of motion pictures. This essay illustrates the application of this methodology through a detailed analysis of Terry Gilliam's film, The Fisher King.
Mathematical Programming Approaches to the Three-Group Classification Problem
In the last twelve years there has been considerable research interest in mathematical programming approaches to the statistical classification problem, primarily because they are not based on the assumptions of the parametric methods (Fisher's linear discriminant function, Smith's quadratic discriminant function) for optimality. This dissertation focuses on the development of mathematical programming models for the three-group classification problem and examines the computational efficiency and classificatory performance of proposed and existing models. The classificatory performance of these models is compared with that of Fisher's linear discriminant function and Smith's quadratic discriminant function. Additionally, this dissertation investigates theoretical characteristics of mathematical programming models for the classification problem with three or more groups. A computationally efficient model for the three-group classification problem is developed. This model minimizes directly the number of misclassifications in the training sample. Furthermore, the classificatory performance of the proposed model is enhanced by the introduction of a two-phase algorithm. The same algorithm can be used to improve the classificatory performance of any interval-based mathematical programming model for the classification problem with three or more groups. A modification to improve the computational efficiency of an existing model is also proposed. In addition, a multiple-group extension of a mathematical programming model for the two-group classification problem is introduced. A simulation study on classificatory performance reveals that the proposed models yield lower misclassification rates than Fisher's linear discriminant function and Smith's quadratic discriminant function under certain data configurations. Data configurations, where the parametric methods outperform the proposed models, are also identified. A number of theoretical characteristics of mathematical programming models for the classification problem are identified. These include conditions for the existence of feasible solutions, as well as conditions for the avoidance of degenerate solutions. Additionally, conditions are identified that guarantee the classificatory non-inferiority of one model over another in the training …
Autophosphorylation and Autoactivation of an S6/H4 Kinase Isolated From Human Placenta
A number of protein kinases have been shown to undergo autophosphorylation, but few have demonstrated a coordinate increase or decrease in enzymatic activity as a result. Described here is a novel S6 kinase isolated from human placenta which autoactivates through autophosphorylation in vitro. This S6/H4 kinase, purified in an inactive state, was shown to be a protein of Mr of 60,000 as estimated by SDS-PAGE and could catalyze the phosphorylation of the synthetic peptide S6-21, the histone H4, and myelin basic protein. Mild digestion of the inactive S6/H4 kinase with trypsin was necessary, but not sufficient, to activate the kinase fully
The Impact of Word Processing on the Written Expression of Students with Learning Disabilities in the Area of Written Expression
The purpose of this study was to investigate the effect of word processing on the quality of written expression of students with learning disabilities identified in the area of written expression. A examination of existing research revealed that most studies do not focus on word processing independent of writing instruction. Therefore, the consensus among researchers that word processors make a difference is limited by the influence of instruction within the research setting. Therefore, this study sought to determine the impact made solely by word processing by controlling for instruction. The 75 students who participated in the study represented three groups--students with learning disabilities identified in the area of written expression (LD-W), students with learning disabilities identified in an area other than written expression (LD-O), and general education students (NA). Each student completed four writing samples: (a) descriptive - handwritten, (b) informative - handwritten, (c) descriptive - word processed, and (d) informative - word processed. The writing samples were scored according to the TOWL-3 on the three Spontaneous Composite subtests (e.g., Contextual Conventions, Contextual Language, and Story Construction). In addition, Word Perfect 6.1- Grammatik was used to determine the number of syllables, words, and sentences in each writing sample. A multivariate analysis of variance (MANOVA) was used in the analysis in conjunction with univariate F-Tests and Tukey's Honestly Significant Difference (HSD) test. General education students scored consistently higher than LD-W on all subtests even when handwriting and word processing were considered. They also generated more syllables, words, and sentences than students with learning disabilities. In addition, all students scored higher on subtests when writing descriptive samples rather than writing informative samples. No practically significant results were determined for the effect of word processing. Therefore, word processing alone does not have an impact on students' quality of writing. It is simply a …
Experimental Analysis of Self-injury With and Without Protective Equipment
Outcomes of experimental analyses during which protective equipment (PE) was placed on three participants were compared to those during which PE was not provided to them. Experimental analysis conditions were presented using a multielement format, and the effects of PE were evaluated using a withdrawal design. Results of experimental analysis without PE suggested that self-injurious behavior (SIB) was maintained by negative reinforcement for two participants and nonsocial mechanisms for the third participant. However, SIB was eliminated either immediately or eventually for all participants when PE was provided during experimental analysis. Thus, outcomes of assessments with PE did not match those without PE, and no conclusion about variables associated with SIB could be drawn from experimental analyses with PE alone. Therefore, the present findings do not support the use of PE as an alternative to standard methods for conducting experimental analysis (i.e., without PE).
A Descriptive Study of Student Assistance Programs in the State of Texas
The purpose of this study is to examine the four basic student assistance models and determine their distribution in Texas, describe the student assistance programs in place in public school districts in Texas including the program's goals, objectives and components, and explore the perceived effectiveness of student assistance programs as a viable means of drug and alcohol education for students enrolled in public school districts in Texas in kindergarten through twelfth grade.
An Analysis of Texas Special Education Due Process Hearings from September 1, 1983, to September 1, 1992: Implications for the Administration of Special Education Programs
The purpose of this study was to assess the effects of selected characteristics on the outcomes of those special education due process hearings brought forth in the state of Texas from September 1, 1983, to September 1, 1992. A further purpose was to determine if district characteristics of size or location affect the likelihood of a district's becoming involved in a special education due process hearing. Data for the study was collected for all special education due process hearings conducted in the State of Texas from September 1, 1983, to September 1, 1992. A coding system was used to record the data for the study and the Chi-square test of independence was used to determine whether a relationship existed between the selected variable (hearing issue, disability classifications and restrictiveness of placement) and hearing outcome. The frequency of involvement in hearings for districts of various size and urban characteristics was displayed as a percentage.
Cultural Differences in Pain Experience and Behavior among Mexican, Mexican American and Anglo American Headache Pain Sufferers
Review of previous research on cultural differences in pain experience and/or pain behavior revealed that cultural affiliation affects pain perception and response. Unfortunately, the many inconsistent findings in the literature on cultural differences in pain experience and behavior have made interpretations and comparisons of results problematic. These inconsistent findings could be attributed to variations in acculturation level among cultural groups. The purpose of this study was to investigate cultural differences in pain experience (assessed by McGill Pain Questionnaire, the Box Scale, the Headache Pain Drawing, and the Headache Questionnaire) and pain behavior (measured by determining medication use and interference of daily functioning due to headaches) among Mexican (n = 43), Mexican American (n = 36), and Anglo American (n = 50) female chronic headache pain sufferers. The contribution of acculturation to differences in pain experience and behavior among cultural groups was measured by the Acculturation Rating Scale for Mexican Americans. The three cultural groups of women significantly differed on pain experience and pain behavior. Specifically, Mexican women experienced their headache pain more intensely, severely, and emotionally than Mexican American and Anglo American women. Furthermore, Mexican women were more willing to verbally express their pain than the other two groups. As for pain behavior, Mexican women took more medication and reported more severe inhibition of daily activities due to headaches than Mexican American and Anglo American women. Ethnic identity, ethnic pride, and language preference were factors in the acculturation process which contributed the most to women's chronic pain experience and behavior. The greatest variability occurred within the Mexican American group of women who perceived themselves as being more Mexican in attitudes and/or behaviors, but more similar to Anglo American in their pain experience and pain behavior. Results are explained using biocultural multidimensional pain theory, social learning theory, and acculturation theory.
Assessment of Essential Competencies in the Hospitality Industry
The hospitality industry in recent years has become intensely competitive. Better communication between industry professionals and educators is important for university programs to provide relevant learning experiences for students. The purpose of this study was to determine competencies that hotel and restaurant professionals deem necessary for the success of graduates in the industry. Thirty supervisors of hotel and restaurant management majors who graduated from the University of North Texas from 1990 through 1992 responded to the research questionnaire. The supervisors were given 36 competencies and asked to rate their level of importance. Percentages were used to identify the most important competencies. The skills most frequently identified as important by the industry professionals surveyed were leadership skills, professional ethics, personnel management, and understanding the different laws that affect hospitality operations and management.
An Examination of Regular Education Elementary Teachers' Attitudes Toward Students with Emotional/Behavioral Disorders
This study examined the attitudes of regular education teachers at the elementary school level, toward mainstreaming students with emotional/behavioral disorders (E/BD) and identified variables which were correlated with those attitudes.
Library CD-ROM LAN Performance and Patron Use: a Computer Simulation Model
In this study, a computer simulation model for library CD-ROM LAN systems was created. Using this model, the system optimization problems were examined. The simulation model imitated the process of the actual decision variables changing their values and generated the corresponding results. Under a certain system environment, if the values of decision variables are changing, the system performances are getting changed also. This study investigated these relationships with the created model. The system users' interarrival time, service time, and other relevant data were collected on randomly selected days in a university library. For data collection, both of the observation and the system automatic metering software were used. According to the collected data, a discrete events simulation model was created with GPSS/H. The simulation model was proven valid and accurate by a pilot test and by the calculation with queuing theory. Statistical tests were used for data comparison and analysis. In addition, animation technique was used to show the simulation process by using Proof Animation. By this technique, the simulation process was monitored on the screen.
Ecological Association Between the Red-Cockaded Woodpecker and Southern Pine Beetle in the Homochitto National Forest: a Geographic Information System Approach
Since the introduction of management practices by the Forest Service to stabilize red-cockaded woodpecker (RCW) populations, the number of cavity trees killed by southern pine beetles (SPB) has increased. A model of the landscape ecology of RCW and SPB in the Homochitto National Forest was created using data collected from the Forest Service and Global Atmospherics. The conclusions of the study were that the RCW and SPB utilize the same type of habitat and the stand hazard maps are an accurate means of determining the locations of SPB infestations. The functional heterogeneity maps created for the SPB and RCW would be useful predictors of future occurrences of either species if complete data were obtained.
Predictors of Compliance and Aggressive Behavior in the Presence of Command Hallucinations
The Schedule for Affective Disorders and Schizophrenia-Change Version (SADS-C), the Social Adjustment Scale-Patient Version II (SAS-PATII) and the Command Hallucination Questionnaire (CAQ) were administered to 86 psychotic inpatients to investigate the relationship between command hallucinations, aggressive behavior, and compliance. Two SADS-C items ("severity of hallucinations" and "depersonalization") were useful as indicators of command hallucinations. Ninety-two percent had complied with their command at least once in the past month. Three SADS-C variables related to compliance with command hallucinations were identified: middle insomnia, the belief that the voice was acting in your best interest, and overt irritability. The patients' level of distortion of reality did not appear to influence compliance rates. Results also indicated that patients who experience command hallucinations were not significantly more or less dangerous than other psychotic inpatients.
Overcoming the Regional Burden: History, Tradition, and Myth in the Novels of Cormac McCarthy
In Overcoming the Regional Burden: History, Tradition, and Myth in the Novels of Cormac McCarthy, I contend that McCarthy's literary aesthetic develops and changes as he moves from Tennessee to Texas. McCarthy's conspicuous Southern and Southwestern regional affiliations have led critics to expect his works to recapitulate native history, traditions, and myths. Yet, McCarthy transcends provincial regionalism by challenging the creation of the regional and national myths we confuse with our actual histories and identities. McCarthy's fictions point away from accepted histories and point instead to figures marginalized by society and myth makers. These figures, according to McCarthy, are just as much a part of the creation of myth as those figures indelibly imprinted on our consciousness by literary and historical tradition. My dissertation, in many respects, focuses on McCarthy's debunking of both literary and historical tradition, and his concomitant revitalization of American identity.
The Stopping Power of Amorphous and Channelled Silicon at All Energies as Computed with the Binary Encounter Approximation
This thesis utilizes the binary encounter approximation to calculate the stopping power of protons penetrating silicon. The main goal of the research was to make predictions of the stopping power of silicon for low-energy and medium-energy channelled protons, in the hope that this will motivate experiments to test the theory developed below. In attaining this goal, different stopping power theories were compared and the binary encounter approach was applied to random (non-channelled) and high-energy channelled protons in silicon, and these results were compared with experimental data.
π-regular Rings
The dissertation focuses on the structure of π-regular (regular) rings.
Development and Testing of a Resource-Based Theory of International Entry Mode Choice
A firm can deploy a variety of arrangements (entry modes) like wholly owned subsidiaries, joint ventures, contracts, and export modes to implement its product market strategies in foreign countries. Each of these arrangements entails decisions about the location of production facilities and/or marketing operations, and the type of ownership of these operations. The choice of an entry mode is of strategic importance to a firm because it can involve investment of substantial amount of resources and has a strong bearing on the firm's marketing mix. Due to its strategic importance, the entry mode choice phenomenon has been extensively researched. In the past, seven major theories have been proposed but none is able to explain the choice from the complete set of entry modes. Thus, there exists a gap between the theory and practice of entry mode choice. This study provides breakthrough on two fronts. First, it develops a new theory of entry mode choice grounded in the resource-based perspective of the firm. The theory posits that the decision to locate its production and/or marketing operations in a country is related to the actualizability of the firm's competitive advantage in that country. However, the ownership decision is related to the sustainability of that advantage. Second, based on this theory, a model is developed which explains entry mode choices from the complete set of entry modes. Mail survey responses of Presidents/CEOs of 163 American firms with international operations support the model. The proposed framework is an effort to fill the gap between theory and practice of entry mode choice. It is expected to make a substantial contribution toward developing a sound theory of international operations of the firm. The framework is broader in scope than the extant theories because it transcends across industries and nationalities of firms.
A Process Analysis of Lenders' Use of FAS 95 Cash Flow Information
This study uses concurrent verbal protocol analysis to examine the decision processes of lenders as they evaluate the financial information of a loan applicant. Of specific interest is the lenders' use of Statement of Financial Accounting Standards Board No. 95 (FAS 95), Statement of Cash Flows, in that decision process.
An Examination of the Presence of Schön's Concept of "Reflective Conversation" as a Defining Component in the Applied Studio Music Lesson
The purpose of this study was to examine the presence of Schön's concept of reflective conversation as a defining component in the applied studio music lesson. The research problems were (1) to determine the presence of complete and incomplete reflective conversations; (2) to determine the verbally exhibited knowledge base within complete conversations in relationship to conversation length; and (3) to establish an instructional profile of stable behaviors based on reflective conversation as a distinguishing characteristic among selected teachers. Videotapes of twenty-six applied studio music lessons of thirteen university teachers were analyzed according to problem solving, on-the-spot experimentation, and evaluation. An observation form was developed and was a reliable tool to collect information concerning number and type of reflective conversations, conversation length, and the teachers' verbally demonstrated knowledge base. Knowledge base was obtained by using the procedural model of Flanagan's critical incident technique. Reflective conversations existed and were a distinguishing characteristic of the teachers. With the exception of two teachers, a stable use of both number and length of reflective conversations, and knowledge base areas, was found. A discernible difference in the teachers' knowledge base within conversation length existed, and thus established instructional profiles for the teachers. Complete reflective conversations ranged from one-sixth to over half of total lesson time. Within instrument categories, teachers generally revealed a dissimilar knowledge usage. Some teachers exhibited fast-paced problem solving, in one minute or less, and named one or two knowledge areas. Others had longer conversations, up to five minutes, with more deliberate problem solving, and as many as twelve knowledge areas named. Results indicated that a practically significant situation can be examined by establishing teacher instructional profiles based upon reflective conversation. Methods employed in this study could be used to document teacher problem-solving and teacher knowledge in a variety of settings.
A Study of Factors of Creativity in Three Selected Fields of Study
The purposes of the study are to identify factors of creativity which have been revealed in the fields of personality and cognitive theory, art education, and science, and to formulate a base for a theory of creativity.
A Study of Administrative Leadership Styles of the Senior Administrators of Public Universities in Texas
The study of leadership in education, business, industry, government, and other organizations has evolved over time. Early studies focused on leadership traits and behavior. Currently, researchers and theorists have concentrated on the interaction of leadership styles and situations. The primary purpose of this study was to determine the predominant leadership style of a group of senior administrators of public universities in Texas.
Critical Thinking Skills Related to Pre-Clinical Medical School Course Examinations
The major purpose of this study was to determine if pre-clinical medical school course examinations reflect critical thinking skills. The entire second year class from a medical school in the southwest made up the population. Student examination results from the first two years as well as scores on the Watson-Glaser Critical Thinking Appraisal were used in this study.
The Determinants of Federal Spending for the Administration of Justice
This study develops and empirically tests a model of the determinants of federal spending for crime-fighting policies. An inter-disciplinary approach to building the model is utilized that merges ideas from budgeting, policy analysis and criminology. Four factors hypothesized to impact federal spending for the administration of justice are operationalized as eight variables and tested using ordinary least squares regression analysis on time series data. The factors hypothesized to impact federal spending in this area are economic constraints imposed on government spending, the ideological makeup of Congress and the president, the actual crime rate, and the public's attitude toward crime. Five of the eight variables demonstrated statistical significance at the.10 level or better.
Roy Harris' American Symphony - 1938: A Perspective on Its Historical Significance and Autogenetic Elements With a Performance of a Reconstructed Modern Wind Ensemble Edition
American composer Roy Harris began writing a symphony for the Tommy Dorsey band in 1938, but the piece was never completed. This dissertation project chronicles the events surrounding the interesting collaboration between the composer and the bandleader, including problems incurred during the rehearsal process, the eventual abandonment of the project, and the discovery of the little-known band work. The paper includes information on the composer's life and works, an in-depth discussion of the compositional technique that Harris called “autogenesis,” and a detailed analysis of the two surviving movements of the band piece. The piece is also discussed comparatively with other significant works in Harris' symphonic genre, most notably his Folksong Symphony, also known as his Fourth Symphony. A significant portion of the research and preparation for the project was spent reconstructing a modern wind ensemble edition of the two surviving movements. A complete score of the reconstructed edition is included as part of this project.
Syntheses of Antimetabolites
In these studies several different types of antimetabolites were synthesized, and their biological effects were examined in various assay systems. More extensive investigations were done in microbial systems in which many of the compounds proved to be inhibitory to growth, and attempts were made to determine the mode of biochemical action by adding supplements of the appropriate natural metabolite.
The Effects of a Conflicting Instruction on a Fr 5 Performance
The purpose of this experiment was to evaluate the effects of a conflicting instruction on FR-5 performances by an ABABC design. After all four college students were consistently pressing 1-5-3 followed by sound-clips, the schedule value changed to FR-5 (A). Then they were presented with the written instruction "Press 426" (B) in addition to the previous condition. In the last condition (C), 1-5-3 responses were then scheduled for extinction in three participants and the reinforcer was changed from sound-clips to points for one participant. The results showed that unlike previous experiments, instructions did not override the scheduled contingencies. Instruction-following occurred only when there were no other contingencies (i.e., extinction of 1-5-3) or the scheduled reinforcer for FR-5 performances was weak.
The Effects of Parenting Stress and Academic Self-Concept on Reading Ability in a Clinic Referral Sample
This study investigated the relationships among the variables of parenting stress, academic self-concept, and reading ability. The purpose of this study was to determine whether parenting stress and academic self-concept contributed to the child's reading ability. Two hypotheses were investigated in an effort to accomplish this purpose. The subjects used in this study were forty-nine children and their primary caretakers referred to The Child and Family Resource Center, The University of North Texas, Denton, Texas, during the academic years of 1994 through 1999. Subjects ranged in age from seven to eighteen years of age. Academically, the subjects ranged from first graders through eleventh graders. All subjects lived in and attended schools in Denton County or neighboring counties. Parental employment ranged from unskilled laborers to medical doctors. The participating families included biological, step, adoptive, single, and divorced families. Abidin's Parenting Stress Index was used to measure parental stress experienced by the primary caretaker. The Intellectual and School Status cluster of the Piers-Harris Children's Self-Concept Scale was used to measure the child's academic self-concept and the Woodcock Reading Mastery Test-Revised provided a measure of the child's reading ability. Test scores were obtained following a review of The Child and Family Resource Center's documented files. Multiple regression statistics revealed no significant relationship between neither parenting stress and the child's reading ability nor the child's academic self-concept and reading ability. Standardized beta coefficients and bivariate correlation results indicated a relationship between academic self-concept and reading ability. Additional research is recommended for future research that encompasses a larger and more diverse sample.
Effectiveness of Filial/Play Therapy Training on High School Students' Empathic Behavior with Young Children
This study was designed to determine the effectiveness of a filial/play therapy training model with high school juniors and seniors enrolled in a Peer Assistance and Leadership program (PALs). Filial/play therapy is an intervention that focuses on strengthening and enhancing adult-child relationships. The high students are trained to be a therapeutic change agent for primary school children identified as having adjustment difficulties by utilizing basic child-centered play therapy skills in weekly play sessions with young children. Specifically, this study is designed to determine the effectiveness of filial therapy in increasing: 1) the high school students' observed empathic behavior with young children, 2) the high school students' observed attitude of acceptance toward young children, 3) the high school students' observed ability to allow self-direction in young children, and 4) the high school students' observed level of involvement with young children. The experimental group, consisting of 16 volunteer high school students enrolled in a PALs class for high school credit, received a total of 24 weeks of filial/play therapy didactic training, application, and supervision for the playtimes they conducted with pre-kindergarten/kindergarten students identified with adjustment difficulties. The comparison group consisted of 15 volunteer high school students enrolled in a PALs class for high school credit. The comparison group received the standard PALs class curriculum. All students were videotaped playing with a young child 4 to 6 years of age before and after the training as a means of measuring empathic behavior with young children. An Analysis of Covariance revealed statistically significant findings in all four hypotheses. Specifically, the experimental group of high school students exhibited statistically significant increases in empathic interactions with young children when compared to the comparison group. The experimental group also exhibited statistically significant increases in communication of acceptance of young children's feelings and behaviors, acceptance and behavioral willingness …
