Considering the explanations of schizophrenia that presume schizophrenia spectrum disorders (e.g., schizotypal personality disorder, schizoaffective disorder, etc.) to be genetically related to schizophrenia, the purpose of this study was to investigate the attention and information processing abilities of individuals who have been identified as schizotypal or psychosis-prone (i.e., schizophrenia spectrum functioning in individuals who do not have schizophrenia). Research indicates that persons identified as psychosis-prone may show attention and information processing deficits similar to individuals with schizophrenia. The identification and description of individuals who later decompensate into schizophrenia would advance the understanding of schizophrenia and its causes. The Chapman's PER-MAG scale (Perceptual Aberration-Magical Ideation) was used to identify 35 hypothetically psychosis-prone college students (schizotypy group) and 42 normal college students (nonschizotypy group) out of the 806 volunteer subjects. Their attention and information processing abilities were measured by COGLAB (a multiparadigmatic cognitive test battery that represents a continuum of cognitive functions, from preattentional to attentional, to conceptual). Their social adjustment was measured by the Premorbid Adjustment Scale (PAS). The hypotheses of the study were that the hypothetically psychosis-prone subjects would perform poorer than controls on COGLAB measures and that COGLAB measures of a more molar nature would better predict social adjustment …

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 …

The purpose of this study was to examine how parental separation is related to eating disturbances and assertiveness in females who struggle with bulimic symptoms. Two-hundred ninety-two undergraduate females from the University of North Texas comprised the subject group. Using pen and paper measures of assertiveness, bulimia, and parental separation, support was found for the prediction that there would be a relationship between assertiveness and parental separation. Likewise, partial support was found for the prediction that there would be a relationship between bulimia and parental separation. Parental separation was found to affect levels of bulimia and assertiveness. Finally, it was found that subjects endorsed greater emotional independence from fathers than from mothers.

The current study examined if students' levels of social physique anxiety vary depending on the type of exercise setting they select. The study determined the degree to which social physique anxiety changed over the course of semester-long involvements in different exercise settings.

This study evaluated the effects of chlorinated effluent discharged from the City of Denton, Texas' wastewater treatment plant on Pecan Creek's fish and macroinvertebrate assemblages, and their recovery upon dechlorination. A baseline of ecological conditions was established while chlorine was present in the effluent (June 1993- October 1993), and was evaluated again after dechlorination with sulfur dioxide (October 1993-August 1994). In situ Asiatic clam and fathead minnow ambient toxicity tests, and fish and macroinvertebrate collections were used to establish this baseline for comparison to post-dechlorination results.

This study was designed to determine the effectiveness of filial therapy with incarcerated mothers as a method of increasing empathic behaviors with their children, increasing attitudes of acceptance toward their children, and reducing stress related to parenting. Filial therapy, a method of training parents to respond and interact therapeutically with their children, focuses on enhancing the parent-child relationship. The sample population of 22 volunteer subjects was drawn from a pool of incarcerated mothers in the Denton County Jail who had children between three and ten years of age. The experimental group parents, consisting of 12 incarcerated mothers, received 2-hour filial therapy training sessions biweekly for five weeks and participated in biweekly 30-minute play sessions with one of their children. The control group parents, consisting of 10 incarcerated mothers, received no treatment during the five weeks. The three written self-report instruments completed for pretesting and posttesting purposes by both groups were The Porter Parental Acceptance Scale, The Parenting Stress Index, and The Filial Problem Checklist. The parents were also videotaped in play sessions with their child before and after training as a means of measuring change in empathic behavior. Analysis of Covariance revealed that incarcerated mothers in the experimental group had …

Self-concept scores of 19 visually-impaired adults were compared to those of 19 matched sighted adults using the Tennessee Self-Concept Scale (TSCS). All participants attended the University of North Texas. Scores were examined against the Vocabulary and Information subtests of the Wechsler Adult Intelligence Scale-Revised (WAIS-R).

This study sought to determine whether there was a difference in subject matter knowledge as measured by a pretest and posttest, a difference in final course grade as a numeric score, and a difference in attitudes toward computers between students in a competency-based ("hands-on") computer applications course taught in an electronically-expanded classroom compared to students taught in a traditional classroom setting. In addition, students taught in the electronically-expanded classroom completed a questionnaire assessing attitudes toward the presentation method. Another purpose of this study was to evaluate the feasibility of applying distance education techniques to teach what was, in essence, an on-campus course. The vehicle for this investigation was an electronically-expanded classroom. The electronically-expanded classroom utilized distance education technology (video, audio, and computer networking) to connect two classrooms in the one building. Students in these two classrooms were the treatment group. Students taking the course in a traditional setting functioned as the comparison group. A total of 109 participants completed the study. Results of the study revealed no significant difference in scores on the subject matter posttest, the final course grade as a numeric score, and attitudes towards computers posttest between students taught the course in an electronically-expanded classroom and students …

Wetland wastewater treatment offers low-cost, energy efficient alternatives to conventional wastewater technologies. In this study, an artificial wetland was constructed at the City of Denton, Texas Pecan Creek Water Reclamation Plant to facilitate diazinon removal from treated effluent.

This study investigated demographic characteristics of 240 Chamber of Commerce members in terms of their expectations for customer service in hotels. Subjects reported their age, gender, marital status, race, educational level, income level and ethnicity, and completed a 26-item questionnaire which measured expectations for customer service. Principal components analysis was used to reduce the 26 items to five dimensions of service quality, and multivariate analysis of variance was used to evaluate the effect of the demographic variables on those dimensions. Gender of the customer was found to have a significant effect on the combined dimensions of service quality; other variables were not significant.

This study examined the neurocognitive skills, incidence of mild head injury, incidence of learning disabilities, and study habits among college students with grade point average of 2.00 or below (N = 25) as contrasted with college students with grade point average above 2.00 (N = 70). The intent of this research was to extend the work of Segalowitz and Brown (1991) and Segalowitz and Lawson (1993) who found significant associations between reported history of mild head injury and developmental disabilities among high school and college samples. MANOVAs conducted on measures of academic achievement, global cognitive skills, verbal and nonverbal memory, motor and tactile functioning, and study habits did not discriminate between probationary and non-probationary students. Probationary and non-probationary students also did not differ with regard to incidence of reported head injury, frequency of diagnosed learning disabilities, and study habits. Measures of neurocognitive functioning and study habits did not contribute to the prediction of grade point average over and above that predicted by Scholastic Aptitude Test composite score. Several exploratory analyses were performed examining the relationship between study habits and neurocognitive skills. Gender differences, implications for future research and development of study skills courses, and limitations of this study were discussed.

With the advent of national storm water regulations, municipalities with populations greater than 100,000 are required to obtain National Pollutant Discharge Elimination System Permits (NPDES) for storm water discharges. In addition to the sampling required for the permit process, the City of Fort Worth contracted with the University of North Texas' Institute of Applied Sciences to conduct acute toxicity testing using Pimephales prcmelas and Ceriodaphnia dubia on storm water samples received from the Dallas/Fort Worth Metroplex. A Toxicity Identification Evaluation (TIE) was performed on four samples that exhibited acute toxicity to C. dubia. High levels of metals as well as diazinon were some of the probable toxicants found.

Even though the Youth Opportunities Unlimited program has been in effect for ten years, there exists no current, comprehensive, effectiveness research on YOU. Such analysis is needed to determine the value of the YOU program. The purpose of this study is to evaluate the effectiveness of the YOU program. Both quantitative and qualitative research methods are used in this study. Quantitative analysis is provided through factual data collected through an alumni survey. Qualitative analysis is provided through personal opinion information obtained from YOU alumni through the survey and by personal interview. The YOU program at UNT is a successful compensatory education program that helps improve the education and the lives of America's at-risk students.
