The Relationship between Self-Reported Bulimic Behavior and Cardiovascular Reactivity to a Weight Stressor
This investigation sought to identify anxiety responses to weight measurement, assessed by verbal report and cardiovascular reactivity CCR3 (systolic blood pressure, diastolic blood pressure, heart rate), which might differentiate females with either high or low self-reported bulimic behavior. Secondar i ly,, the study attempted to examine specific autonomic nervous system (ANS) arousal patterns of each group over time. The Bulimia Test (BULIT), Body Dissatisfaction Scale (BD), and a demographic questionnaire were administered to 105 undergraduate females at The University of North Texas. Based on BULIT scores, females were divided into high or low bulimic behavior groups. Of the 105 females screened, forty participated in the experiment which consisted of four phases: relaxation, anticipation of weight measurement, weight measurement, and recovery. Subjects had no prior knowledge of the weight stressor until presentation during the experiment. Results showed that subjects' notion of ideal weight was substantially lower than measured weight. During weight measurement, all subjects reported increased anxiety although the high group reported significantly more anxiety. Contrary to prediction, no significant group differences in CR were found when repeated measures multivariate analysis of variance (MANOVA) was performed. Orthogonal polynomial trend analysis was done with pooled groups, resulting in significant within-subject trends for …

A Comparison of Adult Children of Alcoholic Families with Adult Children from Non-Alcoholic Families: a Replication
The purpose of this study was to re-examine the issue of whether adult children of alcoholics experience more depression, anxiety, and lower self-esteem than do children of non-alcoholic families. This study is a replication of the study of David Dodd, entitled A Comparison of Adult Children of Alcoholic Families with Adult Children from Non-Alcoholic Families. 1990. The measures used in this study were as follows: Children of Alcoholics Screening Test, the Beck Depression Inventory, the State-Trait Anxiety Inventory, the Coopersmith Adult Self-Esteem Inventory, and a questionnaire developed by this writer designed to obtain family history regarding not only alcoholism, but other issues of family dysfunctionality as well. The subjects for this study were 231 students enrolled in the counselor education program at this university, all aged 19 or older. Of the 230 subjects, 31 were male and 199 were female. Eleven males identified themselves as children of alcoholics, as measured by the Children of Alcoholics Screening Test, and 60 females identified themselves as children of alcoholics. Thus, a total of 71 subjects in this study were identified as children of alcoholics. T-tests were conducted to see whether any differences existed between the male and female groups. No significant differences were …

A Comparison of Points Versus Sounds as Reinforces in Human Operant Research
Research shows that human operant behavior typically differs from non-human operant behavior on schedules of reinforcement. These differences in performance may be related to differences between the experimental preparations used to study human and non-human operant behavior. One such difference is the type of reinforcer used. This experiment analyzed the differential effects of points alone, points backed up by money, and sounds on schedule performance of human subjects. Results show that sounds generated moderate rates of responding, capable of change in either direction. When points backed up with money were the reinforcers, however, high rates of behavior were generated, disrupting the previously established baseline performance. This suggests that while points may be effective in generating high rates of behavior, they may be ineffective in producing sensitive baselines needed to study human operant behavior on schedules of reinforcement.

A Study of the Relationships among Relational Maintenance Strategy Usage, Communicator Style and Romantic Relational Satisfaction
This thesis examined student-participants' self-reported use of romantic relational maintenance strategies and their partners' reports of relational satisfaction. Additionally, individuals outside the romantic relationship reported on student-participants' general communicator style. The research proposed that general style reports would be predictive of relational maintenance strategy usage and of romantic partners' relational satisfaction. The study found that general style behaviors may not be indicative of relational maintenance strategy usage or romantic partners' relational satisfaction. Tests of sex differences revealed that females' expression of various relational maintenance strategies and style behaviors are associated with male partners' relational satisfaction; however, no results were obtained indicating specific behaviors expressed by males result in female partners' relational satisfaction.

The Effects of Career Group Counseling on the Self-Concept of At-Risk High School Students as Measured by the Piers-Harris Children's Self-Concept Scale
The purpose of this study was to determine the effectiveness of career group counseling in raising the self-concept of at-risk high school students. The following subgroups were represented in the sample: male and female students, white and non-white ethnic groups, and students from sophomore, junior, and senior classifications. Two groups of students in the Lewisville Independent School District meeting the criteria for at-risk as defined by House Bill 1010 were administered a pretest and posttest using the Piers-Harris Children's Self-Concept Scale. The experimental group was from the Lewisville Learning Center. The control group was students enrolled in the Coordinated Vocational Academic Education (CVAE) classes at Lewisville High School. A treatment sample of 25 students received career group counseling. A nontreatment sample of 25 students did not receive any group counseling. The t-test for independent samples was used to analyze the data. The pretests for the experimental and control groups showed no significant difference at the .05 level. The treatment sample received 30 hours of group counseling in the Fall semester of 1994. At the end of 30 hours of counseling a posttest was administered to the treatment sample and to the control sample. The t-test for independent samples was used …

Imaginative Involvement and Hypnotic Susceptibility
J. Hilgard (1970, 1972, 1974, 1979), utilizing an interview format, asserted that a personality variable, namely, an individual's capacity to become imaginatively involved in experiences outside of hypnosis, was significantly correlated with his or her hypnotic susceptibility. Tellegen and Atkinson (1974) operationalized the imaginative involvement variable in a 37-item questionnaire, the Tellegen Absorption Scale (TAS) that correlated significantly with hypnotic susceptibility (e.g., Crawford, 1982). However, Council, Kirsch, and Hafner (1986) suggested that the relationship between the TAS and hypnotic susceptibility is a context-mediated artifact in that the two correlate only when the TAS is administered within a context clearly identified as involving hypnosis. As the interviews conducted by J. Hilgard (1970, 1972, 1974, 1979) were done within a context clearly identified as involving hypnosis, the possibility exists that the relationship between imaginative involvement and hypnotic susceptibility is also a context-mediated artifact. In a test of this possibility, 86 subjects were interviewed concerning their imaginative involvements. Forty-three subjects were interviewed within a context defined as "research investigating hypnosis" and 43 subjects were interviewed within a context defined as "research investigating imagination." Hypnotic susceptibility was assessed in sessions separate from the interviews. In the present study, an individual's hypnotic susceptibility was not …

Academic Achievement and the Ability of Post-Secondary Students to Read Assigned Materials
This study provides a rationale for adopting course materials. It demonstrates the relationship between ability to read assigned materials and academic achievement, and that selection of materials creates two groups having different probabilities of success. The sample was selected from a population of all students enrolled in Principles of Economics courses at North Texas State University in the spring semester of 1986. The Nelson-Denny Reading Test was used to determine reading ability. Assigned materials were analyzed for readability. A frustration level was determined and used to divide the sample: the group of interest, those with reading abilities below the frustration level who underwent the treatment of reading materials written above their ability to comprehend; and the comparison group, those with reading abilities above the frustration level who did not undergo the treatment.

A Study of College Stress and Its Measurement
The purpose of the study was to compare the academic stress of freshmen in a community college with that of freshmen in a university. An additional purpose was to determine if gender, ethnicity, or semester course load was related to perceived academic stress. The sample consisted of a total of 303 university and community college freshmen from English and Psychology classes at the University of North Texas and Richland Community College during the spring semester, 1989. The instrument that was administered to these volunteer students was the Academic Stress Test, a 35-item checklist of possible academic stressors. The students were asked to check the items which were perceived by them to be stressful and had occurred during the current semester. The T-statistic was used to analyze the total mean stress score for each variable being considered. Multiple regression was used to determine if there was any possibility that the variables might have a predictive effect for academic stress. It was found that for these freshmen students there was a significant difference between the perceived academic stress of community college freshmen and university freshmen. The mean academic stress score for university freshmen was higher than the mean for community college freshmen. …

A Study of the Relationship between Field-Independent and Field-Dependent Cognitive Styles and Social Behaviors during Free-Play of Preschool Children
The problem of this study was to discover the relationship between field-independent and field-dependent cognitive styles and social behaviors during free-play of preschool children in a school setting. This study also compared the field-independent and field-dependent cognitive styles and social behaviors during free-play between age-groups and sex-groups. Thirty-six children from a university child development laboratory were subjects. They were selected from a 3-year-old classroom and a 4-year-old classroom. The research instrument, the Preschool Embedded Figures Test, was utilized to measure field-independent and field-dependent cognitive styles. The children's social behaviors were observed during free-play for four consecutive weeks. The nine categories of social behavior were solitary, parallel, and group play; .unoccupied, onlooker, transitional, and aggressive behaviors; and conversations with teachers and conversations with peers. Correlations between field-independent and field-dependent cognitive styles and social behaviors indicated that field-independence/field-dependence was related to social orientations in preschool children and also related to the choice of play activity. Field-dependent children tended to engage in conversations with teachers more often than field-independent children. Four-year-old children who were field-independent tended to spend more time in solitary play than 4-year-old children who were field-dependent. Four-year-old boys who were field-independent tended to play more often in the manipulative learning …

Short-to-Medium Term Enrollment Projection Based on Cycle Regression Analysis
Short-to-medium projections were made of student semester credit hour enrollments for North Texas State University and the Texas Public and Senior Colleges and Universities (as defined by the Coordinating Board, Texas College and University System). Undergraduate, Graduate, Doctorate, Total, Education, Liberal Arts, and Business enrollments were projected. Fall + Spring, Fall, Summer I + Summer II, Summer I were time periods for which projections were made. A new regression analysis called "cycle regression" which employs nonlinear regression techniques to extract multifrequential phenomena from time-series data was employed for the analysis of the enrollment data. The heuristic steps employed in cycle regression analysis are similar to those used in fitting polynomial models. A trend line and one or more sin waves (cycles) are simultaneously estimated using a partial F test. The process of adding cycle(s) to the model continues until no more significant terms can be estimated.

The Effect of Sequencing Microeconomics and Macroeconomics on Learning
The purpose of this study was to determine the effect on student learning from the sequence in which microeconomics and macroeconomics courses are taken. The sample for this study consisted of all students enrolled in 23 sections of Economics 1100 (Principles of Microeconomics) and 10 sections of Economics 1110 (Principles of Macroeconomics) during the fall semester, 1987, at the University of North Texas. The sample also consisted of all students enrolled in 14 sections of Economics 1100 and 12 sections of Economics 1110 during the spring semester, 1988, at the University of North Texas. The instruments chosen for use in measuring cognitive gains were two versions, each with 14 items, selected from the Joint council on Economic Educations's Revised Test of Understanding College Economics. Data were analyzed using hierarchical regression on five models. Each model used a different dependent variable to measure cognitive gain. The dependent variables were additive grade points, additive absolute improvement posttest scores, gap-closing posttest scores, microeconomic gap-closing scores and macroeconomic gap-closing posttest scores. The general hypothesis that students who complete microeconomics instruction followed by macroeconomics instruction have significantly higher cognitive gains than students who complete macroeconomics instruction followed by microeconomics instruction was not verified by the …

Les Morceaux de Concours de Flûte du Conservatoire de Paris: A Structural Comparison of Selected Works of Jean-Louis Tulou and Joseph-Henri Altès: A Lecture Recital Together with Three Recitals of Selected Works of Mozart, Halffter, Gaubert and Others
The lecture was presented April 7, 1987. This presentation centered on the flute music literature used for the Concours of the Conservatoire de Paris from 1828 through 1893. The historical parameter began with Jean-Louis Tulou's tenure as flute professor at the Conservatoire and ended with Joseph-Henri Altes'tenure in the same capacity. The Concours is an annual performance competition to determine which students on each instrument will graduate from the Conservatoire. The majority of Concours pieces for flute during the tenures of professors from Tulou through Altes were composed by those two men. Short biographies of Tulou and Altes were presented. Discussion of interim professors Victor Coche and Vincent-Joseph Dorus was included, with focus on the role of these two men in bringing acceptance of the Boehm system flute to the Conservatoire. Tulou's fifteen Grands Solos were compared in form, key center and tonal progression. His themes and passagework are constructed to best display the conical-bore, old system-flute with small toneholes. His Solos continued to be used for the Concours, in alternation with Altes', throughout the tenures of both Vincent-Joseph Dorus and Altes. Tulou's Cinquieme Grand Solo was used for more detailed analysis and performance. Altes wrote his Solos de Concours …

The Use of Learning Theory in the Application of Artificial Intelligence to Computer-Assisted Instruction of Physics
It was the purpose of this research, to develop and test an artificially intelligent, learner-based, computer-assisted physics tutor. The resulting expert system is named ARPHY, an acronym for ARtificially intelligent PHYsics tutor. The research was conducted in two phases. In the first phase of the research, the system was constructed using Ausubel's advance organizer as a guiding learning theory. The content of accelerated motion was encoded into this organizer after sub-classification according to the learning types identified by Gagnds. The measurement of the student's level of learning was accomplished through the development of questioning strategies based upon Bloom's taxonomy of educational objectives. The second phase of this research consisted of the testing of ARPHY. Volunteers from four levels of first-semester physics classes at North Texas State University were instructed that their goal was to solve three complex physics problems related to accelerated motion. The only students initially instructed by ARPHY were from the class of physics majors. When the threshold values of the pedagogical parameters stabilized, indicating the fact that ARPHY's instructional technique had adapted to the class' learning style, students from other classes were tutored. Nine of the ten students correctly solved the three problems after being tutored for …

Recovery of the Fish Population of a Municipal Wastewater Dominated, North Texas Creek After a Major Chlorine Disturbance
This study evaluated the effects of a major chlorine disturbance on fish communities in Pecan creek by the City of Denton's Pecan Creek Water Reclamation Plant. Fish communities in Pecan Creek were sampled using a depletion methodology during February, April, July, and November, 1999. February and April sampling events showed that the fish communities were severely impacted by the chlorine. Sampling during July and November showed fish communities recovered in Pecan Creek. The first-twenty minutes of shocking and seining data were analyzed to mirror an equal effort methodology. This methodology was compared to the depletion methodology to see if the equal effort methodology could adequately monitor the recovery of Pecan Creek after the chlorine disturbance. It was determined that the equal effort methodology was capable of monitoring the recovery of Pecan Creek, but could not accurately represent the fisheries community as well as the depletion method. These data using the twenty-minute study were compared to a previous study. Results of this study were similar to those found in a previous study, although fish communities were more severely impacted and took longer to recover.
