Eighty-seven single custodial fathers were surveyed to test the validity of previously developed typologies and/or construct a more empirically valid framework with implications for adjustment to the role. Mendes1 (1975) aggressive seekers, conciliatory seekers, conciliatory assenters, and aggressive assenters were compared to O'Brien's (1980) hostile seekers, conciliatory negotiators, and passive acceptors. In addition to demographic variables, relationship to ex-wife and child, and reasons for becoming single and obtaining custody, several personality variables were included along with measures of adjustment. One year follow-up measures of adjustment were collected to evaluate implications of typologies in adjustment. Two nearly equal groups were established in a Q type factor analysis of continuous data. Factor loadings of individual cases suggest a continuum of the two types of single fathers, rather than two distinct groups. Group differences were evaluated in a series of MANOVA and Chisquare analyses. Analysis included six factor scores from a supplemental R factor analysis of selected variables. Type I fathers are characterized as older, more passive, selfreflective, and aloof in interpersonal relationships. They are somewhat less oriented toward a relationship with their children and had felt satisfied with their wives* care of them. Alternatively, Type II fathers are younger, active, assured (not …

The problem of this study addressed how women experience the conflict variables of beliefs about conflict, anger arousal, conflict styles, and received and expressed violence as partners in love relationships and how these factors affect their reported satisfaction. Graduate women (M = 186) from University of North Texas completed the Dyadic Adjustment Scale (DAS), a subscale of Relationship Beliefs Inventory (RBI), the Multidimensional Anger Inventory (MAI), and Interpersonal Conflict Tactics and Strategies Scale (ICTAS), and the Severity of Violence Against Women scale (SVAW). Data were analyzed using MANOVAs with ANOVAs to examine significant differences. Multiple regression procedures were used for the exploratory questions. Women reporting less satisfied relationships were expected to believe that disagreement was more destructive and to report higher anger arousal than those who were more satisfied. The hypotheses were supported. Women who were less satisfied also reported using less constructive conflict tactics and more destructive and avoidant tactics as well as receiving some forms of violence. Expressed violence was not significantly related to low satisfaction. Results suggested that these conflict variables are highly interrelated. Strong feedback loops may develop. Strongly held conflict beliefs may affect the use of destructive and avoidant conflict strategies and increase anger which …

The purpose of this study was to test assumptions made about characteristics of nontheatrical film and video works that were thought to contribute to the frequency with which the works were purchased. This study proposed and tested three variables for which relationships to the sales success of nontheatrical film and video works were hypothesized, as well as four variables about which no hypotheses were forwarded. Nineteen film and video distribution organizations contributed unit sales data for the period 1982-1987 on 151 works copyrighted between 1982 and 1984. These data were analyzed for relationships between sales totals and 1) curricular significance of the works' subjects, 2) relevance to general reading interest in the works' subjects, 3) intensity of competition faced by the works, 4) the works' Dewey classifications as compared to the composition of typical K-12 school library book collections, 5) the series or non-series status of the works, 6) the media format(s) in which the works were available for purchase and 7) the sources of the works' production financing. Analyses of correlation and association were performed and no significant relationships were found between sales and curricular significance of the works' subjects, or their relevance to general reading interest. Some evidence …

The factor structure of the Luria Nebraska Neuropsychological Battery (LNNB) Form II was examined. A principle components factor analysis was performed on a sample of 102 psychiatric and neurologic subjects. It was necessary to remove 45 items from the analysis due to perfect performance by most subjects. The results were orthogonally rotated to simple structure using a Varimax method of rotation, and then compared to previous LNNB Form I and Form II results. Thirty-three factors were generated in the Exploratory Factor Analysis (EFA) . There was a very high agreement with the factors from Form I. Only one new factor was identified that didn't have a comparable Form I factor, and this factor appears to have neurological support. The similarity of the factor solutions between the two forms supports the continued use of factors derived from Form I for the interpretation of Form II, and supports the underlying structure presupposed by Lurian constructs. The present study also tested the significance of the hypothesized factor structures through confirmatory factor analysis (CFA). No hypothesis about the underlying factor structure based on previous exploratory studies was supported. The CFA did suggest that the best factor solution to the LNNB Form II is one …

Although ingratiatory behaviors have been investigated by social psychologists for almost twenty-five years, and have been discussed as being used in organizational settings as an upward influence strategy, few empirical studies have explored the use of ingratiation in organizations. The intent of this study has been to empirically investigate the use of ingratiatory behaviors in organizational settings. In doing so, a theory-based rationale for the occurrence of ingratiatory behaviors in organizational settings was developed. The framework developed for this study examined ingratiation as both an individually initiated and organizationally induced behavior. Next, a scale was developed to measure the frequency with which employees resort to ingratiatory behaviors in relationships with their superiors. Finally, a series of research propositions about the occurrence of ingratiatory behaviors in organizations were tested across a variety of organizational settings.

All of Mahler's works may be divided into four distinct chronological groups, referred to as "symphonic cycles." Motives and themes from the songs within each symphonic cycle were quoted in symphonies in the same cycle. This system of self reference was unique to Mahler, although earlier composers such as Schubert and Wagner set precedents for some of the techniques used by Mahler. The quotations in the early periods appeared only on the surface and did not blend well with their surroundings, but as time progressed Mahler developed the ability to combine the seemingly incompatible elements more smoothly. Mahler's early fascination with distant sounds was also a factor in his use of quotations. The appendix contains a catalog of 100 quotations.

The study is a contextual analysis of flood victimization. Victimization is defined as the social, psychological, and physiological aftermath experienced by victims of a disaster. Disaster researchers concentrate on the victims' characteristics to explain the varying degrees of their victimization, providing only ambiguous results. Theorists such as Kreps, Wildavsky, and Douglas contend that the outcomes of disasters are contingent upon social structure. This analysis treats victimization as one such outcome. The condition and behavior of individuals can be explained by the presence of disaster and the conditions of social organization. A model explains victimization based on individual's attributes (individual resources), his social environment, and the disaster characteristics. This study uses the 1984 Mingo Creek Flood Victims Survey data to test the model. The data contain information measuring victimization. The survey data are linked with 1980 Census tract data. The tract data provide indicators of the social networks. This tract information, the contextual variables, taps the social conditions, including poverty, unemployment, geographic mobility, and family patterns. This study uses factor analysis to identify the dimensions of victimization. Regression tests the relationship between the contextual variables, the individual resource variables, the disaster characteristic variables, and victimization. The results of the analysis show …

Academic freedom has gone through three distinct eras yet each era overlaps a great deal with the one following it. The first era was the bureaucratic. It was exemplified by the negotiations between administrators and professors in the 1920s. The American Association of University Professors and the American Association of Colleges began cooperating and a hierarchical structure emerged, with the tenured professor at the top of the faculty. The second era was the political era and it was mainly a result of loyalty oaths, which began after the first World War and then escalated again during the 1930s when communism became a major concern. The political era then gave way to the legal era when the first academic freedom cases went to the United States Supreme Court in the 1950s. The first cases were the result of political pressures that became legal pressures. Most of the early court cases were based on communism. The legal era has produced changes. There are now more rights; for students and teachers of all levels, including pre-college levels, are guaranteed some academic freedom rights. However, the First Amendment and academic freedom are not synonymous because a professor usually cannot win a case based solely …

The purpose of this study was to determine the interrater reliability of the Texas Teacher Appraisal System instrument. The performance indicators, criteria, domains, and total instrument were analyzed for inter rater reliability. Five videotaped teaching episodes were viewed and scored by 557 to 881 school administrators trained to utilize the Texas Teacher Appraisal System. The fifty-five performance indicators were analyzed for simple percentage of agreement. The ten criteria, four performance domains, and) the whole instrument were analyzed utilizing Ruder-Richardson Formula 20. Indicators were judged reliable if there was 75 percent or greater agreement on four of the five videotaped exercises. Criteria, domains, and the whole instrument were judged reliable if they yielded a -Ruder-Richardson Formula 20 score of .75 or greater on four of the Based on the findings of this study, the following conclusions v/ere drawn: 1. Forty-eight of the fifty-five performance indicators were reliable in evaluation teacher performance. 2. Seven of the performance indicators were unreliable in evaluating teacher performance. 3. None of the ten performance criteria appeared to be reliable in evaluating teacher performance. 4. None of the four performance domains appeared to be reliable in evaluating teacher performance. 5. The whole instrument was reliable in evaluating …

My work already shared some of the characteristics of the gravesites that I proposed to study. They were similar in that they both attempted to integrate sacred and profane imagery. Both called attention to personal events and related these events to a larger scheme. Finally, both were involved with the creation of objects of veneration according to personal edicts, but in relation to already established mythologies. I proposed to create a body of work based on the information gathered from the investigation of three predominantly Mexican graveyards-- one in Nuevo Laredo, Mexico, and two outside of Laredo, Texas.

The purpose of this study was to compare the speaking fundamental frequency, physiological vocal range, singing voice quality, and self-perceptions of the singing and speaking voice between two groups of girls ages 11 through 15 years, who were pre-menarcheal by 6 months and post-menarcheal by 10 months or more. Subjects were volunteers who attended a North Texas public school system. Each subject was examined by an otolaryngologist. Age, height, weight, a hearing screening, and information on music classes and/or private music lessons were obtained. The speaking fundamental frequency measure was obtained by having each subject speak for 30 seconds on a subject of choice and read a passage of approximately 100 syllables. The vocal range measure was obtained by having each subject begin at an arbitrary pitch and sing mah and moo up the scale as high as possible and mah and moo down the scale as low as possible. These four measures were repeated with the researcher giving visual gestures. For singing-voice quality, each subject sang "America" in the key of her choice and again in the key of F major. Each subjects singing voice was rated according to breathiness. Data regarding self-perceptions of the singing and speaking voice …

Discusses the creation and performance at a concert on Feb. 12, 1990, in the Merrill Ellis Intermedia Theater at the University of North Texas of three computer music-intermedia compositions: Shakespeare quartet for 4 acoustic guitars; A noite, porem, rangeu e quebrou, for instrument of low pitch range, tape and computer; and Help me remember, for performer, Synclavier, interactive MIDI computer music system and slides.

This dissertation presents a thematic study of the novels of John Nichols. Intended as an introduction to his major works of fiction, this study discusses the central themes and prominent characteristics of his seven novels and considers the impact of the Southwest on his work. Chapter One presents biographical information about Nichols, focusing on his political awakening and subsequent move to Taos, New Mexico. A visit to Guatemala, after the publication of The Sterile Cuckoo. his first novel, brought Nichols to a realization that America was not a benevolent world power. He began to consider capitalism a voracious, destructive economic system, a view which informed the subjects and themes of his five novels written after The Wizard of Loneliness. In 1969, Nichols left New York City, moving to Taos, New Mexico, an area with a history of physical and economic aggression against its predominantly Native American and Hispanic population. The five polemical novels, all set in northern New Mexico, were written after this move. Chapters Two through Four discuss Nichols's seven novels, analyzing theme and reviewing critical response. /V Chapter Two discusses The Sterile Cuckoo (1965) and The Wizard of Loneliness (1966), novels written prior to Nichols's political awakening. Both …

Ernst Krenek is noted and often criticized for the diversity of his overall output. However, one finds that his entire output is held together by a unique temperament regardless of stylistic changes. It is significant to compare the piano works to one another as the piano was the instrument he repeatedly turned to while testing new stylistic ideas. In writing about Krenek's music, Glenn Gould states eloquently and concisely that three qualities prevail in all of Krenek's mature output: the lyric, elegiac, and euphonic. These qualities are present in the early Toccata und Chaconne uber den Chorale, "Ja, ich glaub an Jesum Christum," Op. 13. It is lyrical in that melody is of utmost importance. One finds that melodic writing prevails in the other piano works as well regardless of when they were written. The elegiac also permeates the work. The Toccata and Chaconne shares with other later works this quality of seriousness, repose, and deep meaning. The Toccata and Chaconne is also euphonic. Krenek's overall style is one which does not shock or offend an audience. In a detailed comparison of the Toccata and Chaconne to later piano works, one may clearly see what Krenek specifically does musically to …

The primary purpose of this study was to determine the marketing strategies for attracting students who have nonreligious vocational goals (NRVG) that are employed by Bible colleges that are either accredited or candidates for accreditation of the American Association of Bible Colleges (AABC). Primary subpurposes were to determine the AABC's interest in marketing themselves.to NRVG; practice of educational marketing strategies toward NRVG; career planning programs and placement services available to NRVG; approaching employers with placement services for NRVG; making available seminars, placement services, and alumni networking for NRVG; and difference in marketing to NRVG according to a colleges' denomination, size, three year growth pattern, and estimated percentage of NRVG. An overview of the literature pertaining to educational marketing and marketing for a liberal arts education was given. The population chosen for this study was the accredited (87) and candidate for accreditation (15) Bible colleges of the AABC (102). Eighty (78.4%) colleges actually responded. The design of this study was survey research using a mailed questionnaire as the principal source of data collection. The statistics utilized were parametric (e.g., one-way analysis of variance and t test) and nonparametric (e.g., chi square). The results of the study indicated that AABC colleges were …

This qualitative study was conducted in a large north Texas school district. The subjects were four elementary teachers who had previously attended a summer aerospace education workshop. The researcher observed in each classroom during science instruction and other areas where aerospace concepts might be taught to determine material usage, practices, and perceptions associated with teaching aerospace. The teachers' lesson planbooks, textbooks, and supplementary materials were also examined by the researcher. Interviews were conducted with each teacher's principal and the district science coordinator to determine their effects on the practices and perceptions of the subjects.

This research tested the hypothesis that militarization of societies, as defined by the percent of national budgets spent on military expenditures, has adverse effects on women's economic status relative to men's. This study also examined other predictor variables known to affect women's status. Data from sixty different nations were analyzed by means of multiple regression techniques. Results show that the militarization variable increased women's share of agriculture, which suggests that as men are mobilized into military activities, women are left to produce food for the country, a situation which can have contradictory effects on women's economic status. What is more important than militarization in predicting women's economic status relative to men's are high birth rates and sex ratios, which clearly depress women's economic opportunities.

The present longitudinal study examined the effects and interactions of several variables thought to affect adjustment to conjugal bereavement. Questionnaires were administered to 147 conjugally bereaved subjects and to 46 persons bereaved of close relatives other than spouse. Independent variables included experienced competence (self-esteem, locus of control, coping self-efficacy, and prior coping strategies), impact of loss (anticipation and preventabillty of loss, centrality of relationship and life change), and perceived resources. All of the independent variables were found to be important predictors of adjustment in conjugal bereavement. However, hypothesized interactions among variables were generally not found. Experimental variables were better predictors of adjustment in conjugal bereavement than were demographic variables. Contrary to prediction, widowed subjects tended to become more lonely and showed increased bereavement adjustment difficulties over a six month period of time. However, post hoc analysis suggested that levels of adjustment do not decline over the long term in widowhood. The present study supports a view of widowhood as a multidimensional event, characterized by seemingly contradictory feelings, experiences, and behaviors.

Research provides biological and ecological information on Hydrilla Verticillata (L. f.) Royle in Gatun Lake, Panama for an ongoing management program of aquatic weeds in the Panama Canal. Morphological and genetic variation, standing crop and life cycle were determined.

Hemingway claims in Green Hills of Africa that "all modern American literature comes from one book by Mark Twain called Huckleberry Finn." If this basic idea is applied to his own work, elements of Adventures of Huckleberry Finn appear in some of Hemingway's Nick Adams stories and his novel The Old Man and the Sea. All major characters and several minor characters in these works share the quality of natural innocence, composed of their primitivism, sensibility, and active morality. Hemingway's Nick, Santiago, and Manolin, and Twain's Huck Finn and Jim reflect their authors' similar backgrounds and experiences and themselves come from similar environments. These environments are directly related to their continued possession and expression of their natural innocence.

Even Though I already did paint fairly rapidly, I felt I had a tendency to let the painting in progress sit too long in between times spent working on it. I also felt that I was spending too much time stepping back away from the work to look at it and was milling around the studio sometimes needlessly. Thus I became intrigued with the idea of doing a painting in one block of time. The purpose of this investigation was to explore and study the possibilities generated by a series of "one-sitting" paintings. I defined one-sitting painting as a painting which proceeded from beginning to end without a significant break, meaning that it could take anywhere from four to sixteen hours to complete.

Opioid/adrenergic interactions were studied to evaluate two hypotheses: (1) naloxone potentiates the effect of epinephrine on cardiac contractility by increasing circulating epinephrine concentrations; and (2) endogenous and exogenous opioids alter left cardiac nerve stimulationinduced norepinephrine release and cardiac function. A canine isolated heart-lung preparation was used for the first study. Plasma epinephrine was determined and myocardial epinephrine uptake was calculated during intravenous epinephrine infusion. Naloxone (4 mg) was given and the epinephrine infusion was repeated. Naloxone increased cardiac contractility, coronary blood flow, and the coronary sinus epinephrine concentration. When coronary blood flow was subsequently held constant (100% above resting), naloxone increased only contractility. This result indicated that the previously observed increase in coronary sinus epinephrine was flow dependent. Corticosterone (an uptake II blocker) was employed as a positive control. Corticosterone increased the contractile response to epinephrine, but unlike naloxone, corticosterone was accompanied by a clear decrease in myocardial epinephrine uptake. The stereospecificity of the response to naloxone was investigated and (+) naloxone equaled or exceeded (-) naloxone in potentiating the inotropic effect of epinephrine. In the second study, the left cardiac nerve was isolated and electrically stimulated in intact dogs. Norepinephrine overflow gradually declined during successive control stimulations. Pretreatment with …

I have conducted detailed experimental and theoretical studies of the nonlinear optical properties of semiconductor materials useful for optical limiting. I have constructed optical limiters utilizing two-photon absorption along with photogenerated carrier defocusing as well as the bound electronic nonlinearity using the semiconducting material ZnSe. I have optimized the focusing geometry to achieve a large dynamic range while maintaining a low limiting energy for the device. The ZnSe monolithic optical limiter has achieved a limiting energy as low as 13 nJ (corresponding to 300W peak power) and a dynamic range as large as 105 at 532 nm using psec pulses. Theoretical analysis showed that the ZnSe device has a broad-band response covering the wavelength range from 550 nm to 800 nm. Moreover, I found that existing theoretical models (e.g. the Auston model and the band-resonant model using Boltzmann statistics) adequately describe the photo-generated carriers refractive nonlinearity in ZnSe. Material nonlinear optical parameters, such as the two-photon absorption coefficient β_2=5.5cm/GW, the refraction per unit carrier density σ_n=-0.8∗10^-21cm^3 and the bound electronic refraction n_2=-4∗10^-11esu, have been measured via time-integrated beam distortion experiments in the near field. A numerical code has been written to simulate the beam distortion in order to extract the …

The Trinity River passes through the Dallas-Fort Worth metroplex receiving point and non-point source contaminant loadings. Lepomis spp. were collected at twelve sampling locations in the Trinity River in August 1987 and September 1988 and analyzed for organochlorine pesticides and heavy metals. Results from the study were compared to existing U.S. FDA action and tolerance levels, LC50s, and historical data. Various longitudinal trends and some concentration patterns were observed. Continual study of pesticide and metal body burdens in fish allow testing for trends, and thereby, lead to a better understanding of the distribution of contaminants in the Trinity River.
