This study investigates the effects of frequency variance on duration perception, using musically trained subjects. In the experiment three silent duration intervals were examined (4.75, 5.00, and 5.25 seconds); each interval was preceded and followed by tone markers. The onset marker was preceded by seven discrete tones one second apart, on the frequency 174.968 Hertz. This established a pulse or an external standard time measure. The subjects made judgments as to whether the offset marker fell "before," "on," or "after," the pulse. The offset marker had a variable frequency. In the study, the direction of the frequency change, the distance of frequency change, and the mathematical intervallic relationships of the two frequencies show possible influence on duration perception.

This investigation of twentieth century trends in mathematics education includes the survey of existing literature and questionnaires conducted with retired and active Texas teachers. Historical events, trends in curriculum, instruction, learning theories, and contradictions of twenty-year periods are delineated. Questionnaire responses are tabulated along the same periods and vignettes of typical classrooms are drawn from the data. Results of the survey show the impact of societal forces on mathematics curricula, a continued downward expansion of content into lower grades and expanding knowledge of learning processes. A unified mathematics curriculum, classroom-related learning theory research, and further development of team-teaching are postulated as future trends. Recommendations include further examination of trends through isolation of other variables such as region and ethnicity.

There have been various approaches to the treatment of nonorgasmic women, including psychoanalysis, desensitization, relaxation, masturbation, and group therapy. The present study was conducted to examine the efficacy of group therapy combined with home-based training in the treatment of primary nonorgasmic women. A no-treatment control group was also employed. Treatment consisted of two weekly 1- hour group sessions for 5 weeks. Educative processes were employed, such as detailed information on physiology of female sexual response. Structured homework exercises were also utilized, such as mastubatory techniques, role-playing orgasm, strengthening vaginal muscles, and assertiveness training in sexual and nonsexual situations. Results indicated an 88% success rate in the treatment group and no change in the control group.

The first chapter discusses the concept of macros: its definition, structure, usage, design goals, and the related prior work. This thesis principally concerns my work on OLMP (an On-Line Macro Processor for the Motorola 6800 Microprocessor), which is a macro processor which interacts with the user. It takes Motorola assembler source code and macro definitions as its input; after the appropriate editing and expansions, it outputs the expanded assembler source statements. The functional objectives, the design for implementation of OLMP, the basic macro format, and the macro definition construction are specified in Chapter Two. The software and the hardware environment of OLMP are discussed in the third chapter. The six modules of OLMP are the main spine of the fourth chapter. The comments on future improvement and how to link OLMP with the Motorola 6800 assembler are the major concern of the final chapter.

This study sets forth events surrounding a law suit filed by Red Lion Broadcasting Co. against the Federal Communications Commission and the Democratic National Committee in 1965. The study found these events were major factors in the decision by John M. Norris, president and owner of Red Lion, to pursue his objection to the FCC's Fairness Doctrine to the U.S. Supreme Court, resulting in the court's landmark decision in Red Lion vs. FCC (1969). Research methodology combined techniques of historical research and case study. On-site research of company records, personal letters and records are included as primary sources.

This thesis considers first, the existence of a relatively new kind of characterization in the plays of Harold Pinter, and second, the need for the actor who performs Pinter to seek a new mode of acting. The purpose of the study is to identify the special problems or tasks which are thus imposed on the actor who plays a Pinter character. An examination of Pinter's dramaturgy reveals an emphasis on character relationships and a combination of the three different styles of characterization defined by Lorenz Kjerbuhl-Petersen: the type, the individual, and the shadow. This study concludes that the Pinter actor must simultaneously perceive a complex psyche in what seems a common human type, create an individualized concept of personality although information and behavior are misleading, and allow the actor's personality to color and expand that of the character.

Historically, horse trainers have relied primarily upon repetition, negative reinforcement, and punishment to teach new behaviors. Positive reinforcement has been eschewed, largely on the basis of the wides read belief that positive reinforcement is not effective with horses. Additional difficulties in the timely application of such reinforcement have further inhibited its use. After repeated pairing of an auditory stimulus with an established primary reinforcer, the auditory stimulus was predicted to be a reinforcer. An equine subject was then successfully trained to perform five different, novel tasks using only the auditory stimulus. Subsequently, extinction of behavior was noted in the absence of the conditioned reinforcer. Implications for many phases of horse training were discussed. Some weaknesses of the present study were noted along with suggested issues for future investigations.

Five learning measures used in a skills training program were related to three types of job performance measures for a sample of 163 oil field employees. Statistical analyses resulted in only modest correlations between learning and job performance criteria. Factor analyses of learning measures followed by multiple regression on factors yielded a significant R with only one criterion measure. It was concluded from these data that the training program was of minimal value. The discussion centered on strategies for better training, training research, job engineering, and correcting the two limitations of this study.

The purposes of the study were to provide additional information concerning the relationship of Competition Trait Anxiety, State Anxiety, and Performance in collegiate golfers under non-competitive and competitive field settings. Subjects were thirty college males. Data were analyzed by a three-way analysis of variance with repeated measures. Conclusions of the investigation were (1) low-Competition-Trait-Anxious golfers performed better and exhibited lower levels of state anxiety than high-and moderate-Competitive-Trait-Anxious golfers in competitive and non-competitive settings; (2) collegiate golfers exhibit higher levels of state anxiety in competitive versus practice settings; and (3) there was a significant relationship between SCAT and pre-competitive state anxiety.

This study is concerned with the historical development and perpetuation of the leisure class in the Colombian society. The study is based on Thorstein Veblen's Theory of the Leisure Class. The main purpose of this study is to analyze in terms of the evolution of social institutions the problems that the Colombian society faces today. Spanish values and traditions are analyzed, as well as more recent values and modes of behavior adopted by the leisure class. Institutions such as the church, the educational, employment and political apparatus are analyzed in terms of how they contribute to the perpetuation of elites. This study concludes that as long as there is economic surplus in society, a leisure class will exist. The elites forming the leisure class may be displaced by counter-elites, which in turn will conform a new leisure class.

Recent sex role research suggested that androgynous subjects demonstrated better adjustment than sex-typed subjects. Fundamentalist religious belief, however, has strongly supported sex role differentiation. This study hypothesized that the effect of appropriate sex role typing or androgyny on self-esteem would depend on religious belief. Although this hypothesis was not supported, a main effect on sex roles for females was obtained; androgynous females had a higher self-esteem level than feminine females. In addition, males in this study had a higher self-esteem level than females.

The problem with which this study is concerned is that of determining what differences, if any, existed between two newspapers with different circulation characteristics and whether the two papers were in competition. The thrice-weekly News-Advertiser and the five-day daily Leader were measured by a content analysis over eight weeks and by a readership and advertiser survey. This study concludes that the two newspapers are in competition in six of eleven designated categories of the content analysis, using Spearman rho and t-tests. However, the two newspapers seemed to be aiming at different markets in Lewisville, because one paper subscribes to a news service and prints thousands of inches of wire news and the other paper is all local news.

Data obtained through interviews with eleven directors of school public information directors and four university chairmen in the Dallas-Fort Worth Metroplex indicated that they are generally satisfied with public relations education being housed in the journalism department, with course format, and with undergraduate study and specialization; and that they are dissatisfied with practitioner-educator relationships. Some of their recommendations included that graduatelevel study be offered more often, and that more emphasis be placed in the curriculum on specific areas of public relations, the social sciences, and the news-editing side of communications studies.

Microcomputer-based music synthesis hardware is being developed at North Texas State University (NTSU). The work described in this paper continues this effort to develop hardware designs for inexpensive, but good quality, sound synthesizers. In order to pursue their activities, researchers in computer assisted instruction in music theory, psychoacoustics, and music composition need quality sound sources. The ultimate goal of my research is to develop good quality sound synthesis hardware which can fill these needs economically. This paper explores three topics: 1) how a computer makes music--a short nontechnical description; 2) what has been done previously--a review of the literature; and 3) what factors bear on the quality of microcomputer-based systems, including encoding of musical passages, software development, and hardware design. These topics lead to the discussion of a particular sound synthesizer which the author has designed.

This study attempted to determine variables significant in predicting use of and changes in use of prenatal care; infant mortality; and the relationship between prenatal care and infant birth weight. The data were collected from birth and death certificates at the Public Health Department in Dallas, Texas. Data were tested using analysis of variance, Scheffe' test, and Chi-square. A mother's age, race, income level, marital status, and parity were found to be significant factors in use of prenatal care, and use of care was found to have begun earlier in recent years. Likewise, birth weight was found to be related to the trimester prenatal care began. Conclusions concerning infant mortality could not be drawn due to insufficient data.

The purpose of this study was to determine whether the themes and values represented in lyrics of progressive country music are significantly different from those of traditional country music. Content analytical techniques were used to determine, first, themes and, second, attitudes reflected in those themes in each type of song. The chi square test of independence was u-ilized, and a difference significant to the .05 level was found between themes and attitudes of lyrics in the two song types.

The present study used regression procedures to investigate the relationships between selected communication variables and innate innovativeness. The three general types of variables examined in this study were communication anxiety, communicator style, and selfdisclosiveness. Ten hypotheses were tested together with a descriptive model which was based on the communication variables and their ability to predict innate innovativeness. Results of the tests of the model were confirmed as were the ten hypothesized relationships. The results of the regression analyses performed on the data indicated that receiver apprehension and honesty of self-disclosiveness were negatively and positively associated with innate innovativeness respectively, and were the variables which most significantly impacted the variance of innate innovativeness scores.

The patient's failure to cooperate effectively in the patient/physician (patient and physician) interaction has been shown to be a problem of significant magnitude. In the present study, an attempt was made to identify specific, patient behaviors which might be related to physician judgment of a good patient and progress of treatment. A checklist of 37 behaviors was compiled. A series of 100 patients was observed during their interaction with physicians and occurrences of behaviors from the checklist were noted by an experimenter. Physicians also indicated whether the patient was considered to be a good patient and whether treatment was progressing as expected. For every third patient, physicians noted the occurrence of behaviors from the checklist. An association was found between some behaviors from the checklist and the physicians' judgment. There was also shown to be a difference in the ability of the experimenter and the physicians involved to detect these behaviors.

This study focuses on the reaction in the United States to Jay's Treaty, 1794-96. Though crucial in the development of American diplomacy, the treaty's greatest impact was on the domestic politics of the young nation. The most important sources were the correspondence of the participants. Other materials include newspapers, diaries, government documents, and secondary sources. The thesis argues that the treaty was in the best interests of the United States, and the nation was fortunate to be led at this time by the Federalist party.

The disabling conditions of chronic low-back pain continue to cost patient, family, and society. The intricate mechanisms which perpetuate this medical condition often consist of both organic and functional factors. This study evaluated personality and psychosocial variables which may control individual responses to facet denervation, a treatment for chronic lumbar distress. The subjects were 47 chronic pain patients whose symptoms conformed to the facet syndrome. Patient responses to the Minnesota Multiphasic Personality Inventory (MMPI) and the Sixteen Personality Factor Questionnaire were reviewed in an effort to predict statistically symptomatic relief. Also, the patients' involvement in litigation and their accuracy in determining their pain level were studied as possible influencing variables. Results show the litigation factor and two scalesof the MMPI to be most useful in predicting patient response from facet denervation treatment.

The purposes of this study were to determine the employment status of North Texas State University clothing and textiles majors who graduated between 1969 and 1978 and to provide a measurement of their job satisfaction. The data were gathered through two mailed questionnaires, a general one developed by the researcher, and the Job Descriptive Index, a standardized job satisfaction index. Graduates in clothing and textiles tended to seek and obtain employment related to their major field of study, and they are generally satisfied with their jobs. Factors tested statistically in this study included age, marital status, parental status, salary, tenure, and organization size. No significant differences in job satisfaction or employment tatus were evident relative to any of these factors.

Genic data from two chromosomal races of Geomys bursarius from a contact zone in central Texas indicated that the two races possessed distinct gene pools which would define them as separate species. Data from proteins encoded from 21 loci in this study substantiated this hypothesis. A pattern of alternately fixed alleles at the ADH-l, MDH-2, LDH-l, and IDH-1 loci with no apparent gene flow in zones of contact strongly suggested that these two races should be designated as separate species. Levels of heterozygosity and high FST values indicate that genomic structuring within Geomys is most heavily influenced by high levels of inbreeding and low migration rates. Fossorial rodents were suggested to undergo speciation primarily through parapatric means.

The proposed interaction between race and sex on achievement orientation has not been adequately demonstrated when cognitive measures are used. Therefore, the present study examined the effects of sex and race on attributions for achievement., Elementary level students made attributions to ability, effort, task-difficulty, or luck for 16 academic successes or failures described in a questionnaire. Girls made significantly (p < .001) fewer ability and significantly (p < .001) more effort attributions on success items than boys, regardless of their race. Six success items that had been sex-typed (3 girl, 3 boy) provided similar results. Sex-typing data indicated these subjects exhibited strong sex-role stereotypy. Results were discussed in terms of sex-typing of the individual and not the task.

In traditional romance, the hero takes a mythical journey into the underworld where he meets and overcomes evil antagonists. Hawthorne has transferred much of that hero's role to a pivotal character whose paradoxical function is to cause the central conflict in the tale or novel while remaining almost entirely passive himself. The movement of the tale or novel depends on the pivot's humanization, that is, his return to and integration within society. Works treated are "Alice Doane's Appeal," "Peter Goldthwaite's Treasure," "Roger Malvin's Burial," "Rappaccini' s Daughter," "Lady Eleanore's Mantle," "The Minister's Black Veil," "The Antique Ring," "The Gentle Boy," Fanshawe, The Scarlet Letter, The House of the Seven Gables, The Blithedale Romance, and The Marble Faun.
