Symptom Based Classification of Environmentally Ill Patients: an Exploratory Study (open access)

Symptom Based Classification of Environmentally Ill Patients: an Exploratory Study

The purpose of the present study was to discern a symptom pattern for environmentally ill patients and provide evidence of the uniqueness of the resultant pattern to this population. Patients' environmental exposure was confirmed by the presence of toxins in the blood serum. All patients were administered psychological and physical symptom checklists, the Clinical Analysis Questionnaire, and a standardized intermediate neuropsychological examination. Results indicate a response pattern of symptoms including fatigue, low energy, weakness, poor concentration, poor memory, poor comprehension, headaches, aches and pains, clumsiness, sinus discomfort, mucus, eye problems, restlessness, and present performance inferior to prior level of functioning. Presence of these symptoms, as well as the uniqueness of this symptom pattern was supported by comparisons of the patient and standardization groups on the two standardized tests.

Organochlorine Pesticides and Heavy Metals in Fish From the Trinity River, Texas (open access)

Organochlorine Pesticides and Heavy Metals in Fish From the Trinity River, Texas

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.

The Angoff Method and Rater Analysis: Enhancing Cutoff Score Reliability and Accuracy (open access)

The Angoff Method and Rater Analysis: Enhancing Cutoff Score Reliability and Accuracy

At times called a philosophy and other times called a process, cutting score methodology is an issue routinely encountered by Industrial/Organizational (I/0) psychologists. Published literature on cutting score methodology appears much more frequently in academic settings than it does in personnel settings where the potential for lawsuits typically occurs more often. With the passage of the 1991 Civil Rights Act, it is no longer legal to use within-group scoring. It has now become necessary for personnel psychologists to develop more acceptable selection methods that fall within established guidelines. Designating cutoff scores with the Angoff method appears to suit many requirements of personnel departments. Several procedures have evolved that suggest enhancing the accuracy and reliability of the Angoff method is possible. The current experiment investigated several such procedures, and found that rater accuracy methods significantly enhance cutoff score reliability and accuracy.

The Organizational Improvement of the Village Creek Wastewater Treatment Plant in Fort Worth, Texas, 1969-1988: a Case Study of Forces Responsible for Organizational Change (open access)

The Organizational Improvement of the Village Creek Wastewater Treatment Plant in Fort Worth, Texas, 1969-1988: a Case Study of Forces Responsible for Organizational Change

This study documents that external and internal forces were causes of change at VCWTP. External forces caused. Fort Worth to reorganize and introduce new management at VCWTP after 1982. These improvements led to VCWTP being selected best managed wastewater treatment plant in the nation by EPA in 1988. This study first analyzes external and internal forces responsible for changes at VCWTP. A history of plant operations also is reviewed. Personnel interviews were conducted of perceptions of employees. Finally, statistics obtained of the plant operation from 1969 to 1988 are compared with personal interviews. Five forces effect change at VCWTP; population, regulatory requirements, political conflicts, an organizational and managerial factors. Turnaround occurred as external and internal corrections were made.

Social Drama at Southwestern Baptist Theological Seminary : The Dilday Controversy (open access)

Social Drama at Southwestern Baptist Theological Seminary : The Dilday Controversy

This study examines the events surrounding the firing of Russell Dilday at Southwestern Baptist Theological Seminary as a social drama. The results suggest that, for application to post-industrial cultures, adaptations need to be made to Victor Turner's original method. The addition of Thomas Farrell's anticipation phase, identification of the breach with the transgression, and examination of unique facets of post-industrial cultures such as economic factors and the role of the media are recommended modifications. In light of these differences, the study concludes that the state of affairs at Southwestern is characteristic of schism in a post-industrial culture.

Plankton Community Response to Dechorination of a Municipal Effluent Discharged into the Trinity River (open access)

Plankton Community Response to Dechorination of a Municipal Effluent Discharged into the Trinity River

Chorine is used by the Village Creek Waste Water Treatment Plant to kill pathogenic microorganisms prior to discharge of the effluent into the Trinity River. The residual chlorine in the river impacted aquatic life prompting the U.S. Environmental Protection Agency in December 1990 to require dechlorination using sulfur dioxide. One pre-dechlorination and four post-dechlorination assessments of phytoplankton, periphyton, and zooplankton communities were conducted by the Institute of Applied Sciences at the University of North Texas. Dechlorination had no effect on the phytoplankton community. The periphyton community exhibited a shift in species abundance with a more even distribution of organisms among taxa. No change occurred in zooplankton species abundance, however, there was a decrease in zooplankton density following dechlorination.

The Effects of Cultural Bias: a Comparison of the WISC-R and the WISC-III (open access)

The Effects of Cultural Bias: a Comparison of the WISC-R and the WISC-III

It has been suggested that the use of standardized intelligence tests is biased against minorities. This study investigates the newly revised Wechsler Intelligence Scale for Children-III in which Wechsler states that the new scale has eliminated biased items. Comparisons of the scores on the WISC-R and the WISC-III of a clinical population of sixteen African American and eighteen Caucasian males, ages ten to sixteen, revealed significant differences between the two groups on the WISC-III. The minority scores decreased predictably from the WISC-R to the WISC-III, but the Caucasian scores increased rather than decreasing. The findings of this study do not support the predictions and goals of revision as stated in the manual of the WISC-III.

Patterns of Relationship Violence among Low Income Women and Severely Psychologically Abused Women (open access)

Patterns of Relationship Violence among Low Income Women and Severely Psychologically Abused Women

Little research has addressed the degree to which domestic violence is mutual and whether patterns are stable across women's relationships. Studies that exist have conflicting results. This study addressed these issues and the effects of sustaining past violence on women's expressions of violence in their current relationship. Archival data from a sample of severely psychologically abused community women (N = 92) and a sample of low-income community women (N = 836) were analyzed. Results showed the presence of mutual violence in women's current relationships which was not related to past partners' violence. Results regarding the stability of violence are weak, but indicate that the frequency and severity of violence across relationships sustained by women does not decrease across relationships. Overall, results supported the hypothesis that violence is mutual in the relationships of community women, although specific patterns may differ by ethnicity.

The Relationship between Work-Family Role Strain and Parenting Styles in Mothers of Young Children (open access)

The Relationship between Work-Family Role Strain and Parenting Styles in Mothers of Young Children

The relationship between work-family role strain and parenting styles (permissive, authoritarian, and authoritative) was examined. Questionnaires were completed by 45 mothers whose children (ages newborn to three years) were enrolled in early childhood centers in the Dallas-Fort Worth-Denton, Texas, area. Participants were primarily Caucasian, high-income mothers who had attended college. Results indicated no significant relationship between role strain and parenting styles. Open-ended questions revealed insights into mothers' reported role strain. This research may provide employers and professionals who work with families with information to assist mothers in reducing role strain. They may also recognize that parenting style may be independent of a successful balance of work and family.

An Assessment of Storm Water Toxicity from the Dallas/Fort Worth Metroplex and Denton, Texas (open access)

An Assessment of Storm Water Toxicity from the Dallas/Fort Worth Metroplex and Denton, Texas

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.

The Development of IAM District Lodge 776 in Fort Worth, Texas, 1942-1946: A Case Study in the Growth of Organized Labor During World War II (open access)

The Development of IAM District Lodge 776 in Fort Worth, Texas, 1942-1946: A Case Study in the Growth of Organized Labor During World War II

This thesis concentrates on a local union of the International Association of Machinists (IAM), District Lodge 776, of Fort Worth, Texas, during the war years. The main argument of the thesis runs along three basic lines. First, it demonstrates that the experiences of the Fort Worth Machinists clearly fit into the national labor movement during the war years. Second, it argues that the existence, survival, and strength of the union depended greatly on outside forcesan expanding national economy, a powerful national union, and a generally labor-friendly government. Third, it shows that union officers and rank-and-file members used their bases of strengththe national economy, the national IAM, and the federal governmentto build an effective local labor organization.
