An Evaluation of the Denton County Safety Education Program in Denton, Texas

Description: The purpose of this study was to assess the effectiveness of the Denton County Safety Education Program. Subjects were 117 driving-while-intoxicated offenders who completed this alcohol reeducation program between June 1975 to June 1976. Questionnaires were used as evaluative measures. Data were analyzed in three steps: 1) two two-way ANOVAs with one repeated measure; 2) two Pearson product moment correlations; and 3) a Fisher's Z test. Conclusions of the investigation were that (1) both problem and non-problem drinkers benefited from the program; (2) change of attitude was an important factor in reducing recidivism; and (3) the program was successful in meeting its goals as a means of influencing drinking and driving behavior.

Evaluation of the Developmental Effects and Bioaccumulation Potential of Triclosan and Triclocarban Using the South African Clawed Frog, Xenopus Laevis

Description: Triclosan (TCS) and triclocarban (TCC) are antimicrobials found in U.S. surface waters. This dissertation assessed the effects of TCS and TCC on early development and investigated their potential to bioaccumulate using Xenopus laevis as a model. The effects of TCS on metamorphosis were also investigated. For 0-week tadpoles, LC50 values for TCS and TCC were 0.87 mg/L and 4.22 mg/L, respectively, and both compounds caused a significant stunting of growth. For 4-week tadpoles, the LC50 values for TCS and TCC were 0.22 mg/L and 0.066 mg/L; and for 8-week tadpoles, the LC50 values were 0.46 mg/L and 0.13 mg/L. Both compounds accumulated in Xenopus. For TCS, wet weight bioaccumulation factors (BAFs) for 0-, 4- and 8-week old tadpoles were 23.6x, 1350x and 143x, respectively. Lipid weight BAFs were 83.5x, 19792x and 8548x. For TCC, wet weight BAFs for 0-, 4- and 8-week old tadpoles were 23.4x, 1156x and 1310x. Lipid weight BAFs were 101x, 8639x and 20942x. For the time-to-metamorphosis study, TCS showed an increase in weight and snout-vent length in all treatments. Exposed tadpoles metamorphosed approximately 10 days sooner than control tadpoles. For the hind limb study, although there was no difference in weight, snout-vent length, or hind limb length, the highest treatment was more developed compared to the control. There were no differences in tail resorption rates between the treatments and controls. At relevant concentrations, neither TCS nor TCC were lethal to Xenopus prior to metamorphosis. Exposure to relatively high doses of both compounds resulted in stunted growth, which would most likely not be evident at lower concentrations. TCS and TCC accumulated in Xenopus, indicating that the compound has the potential to bioaccumulate through trophic levels. Although TCS may increase the rate of metamorphosis in terms of developmental stage, it did not disrupt thyroid function and metamorphosis in ...

Evaluation of the Easter Seals North Texas Autism Treatment Program: Progress in Meeting Program Mission

Description: Applied behavior analysis (ABA) remains at the forefront of effective interventions for children with autism. In some cases, the high cost of treatment and other environmental factors limit families from accessing services. The Easter Seals North Texas (ESNT) Autism Treatment Program (ATP) was created to reach high risk, underserved families in the North Texas area by providing early intensive behavioral intervention (EIBI) services to children with autism. This evaluation was conducted to analyze the success of meeting the ESNT ATP program mission to provide culturally responsive ABA to children. The evaluation includes the design of assessments, the analysis of the assessment data, and a set of recommendations to maintain and increase program accessibility.

Evaluation of the Economic, Social, and Biological Feasibility of Bioconverting Food Wastes with the Black Soldier Fly (Hermetia illucens)

Description: Food waste in the waste stream is becoming an important aspect of integrated waste management systems. Current efforts are composting and animal feeding. However, these food waste disposal practices rely on slow thermodynamic processes of composting or finding farmers with domestic animals capable of consuming the food wastes. Bioconversion, a potential alternative, is a waste management practice that converts food waste to insect larval biomass and organic residue. This project uses a native and common non-pest insect in Texas, the black soldier fly, which processes large quantities of food wastes, as well as animal wastes and sewage in its larval stage. The goal of this research is to facilitate the identification and development of the practical parameters of bioconversion methods at a large cafeteria. Three major factors were selected to evaluate the practicality of a bioconversion system: (1) the biological constraints on the species; (2) the economic costs and benefits for the local community; (3) the perception of and interaction between the public and management agencies with respect to the bioconversion process. Results indicate that bioconversion is feasible on all levels. Larvae tolerate and consume food waste as well as used cooking grease, reducing the overall waste volume by 30-70% in a series of experiments, with an average reduction of 50%. The economical benefits are reduced collection costs and profit from the sale of pupae as a feedstuff, which could amount to as much as $1,200 per month under optimal conditions. Social acceptance is possible, but requires education of the public, specifically targeting school children. Potential impediments to social acceptance include historical attitudes and ignorance, which could be overcome through effective educational efforts.

An Evaluation of the Effect of a Specific Perceptual Training Program on Classroom Skills in Kindergarten

Description: The purpose of the evaluation was to test effectiveness of a visual, visual-motor, and auditory perceptual skills training program devised by Dr. Jerome Rosner, and to confirm or deny application of this training to improved classroom skills. Subjects were 38 kindergarten children, 20 in the Contrast Group, and 18 in the Experimental Group. Both groups received the same training in the basic curriculum of readiness skills. The Experimental Group also received training in the Visual Analysis and Auditory Analysis Skills programs. Pretests and posttests were administered, tabulated, and analyzed. Differences in raw score means were sufficient to indicate more than a chance factor and all tests demonstrated a plus factor for children in the Experimental Group.

An Evaluation of the Effect of Learning Styles and Computer Competency on Students' Satisfaction on Web-Based Distance Learning Environments

Description: This study investigates the correlation between students' learning styles, computer competency and student satisfaction in Web-based distance learning. Three hundred and one graduate students participated in the current study during the Summer and Fall semesters of 2002 at the University of North Texas. Participants took the courses 100% online and came to the campus only once for software training. Computer competency and student satisfaction were measured using the Computer Skill and Use Assessment and the Student Satisfaction Survey questionnaires. Kolb's Learning Style Inventory measured students' learning styles. The study concludes that there is a significant difference among the different learning styles with respect to student satisfaction level when the subjects differ with regard to computer competency. For accommodating amd diverging styles, a higher level of computer competency results in a higher level of student satisfaction. But for converging and assimilating styles, a higher level of computer competency suggests a lower level of student satisfaction. A significant correlation was found between computer competency and student satisfaction level within Web-based courses for accommodating styles and no significant results were found in the other learning styles.

An Evaluation of the Effects of a Pay for Performance Plan on Productivity of Employees of a Professional Services Firm

Description: This study examined the effects of a productivity-indexed pay for performance plan in a professional services firm. The new plan was implemented after productivity decreased under an existing plan. Performance of staff and senior level accountants was analyzed across three departments under a three-year baseline and a two-year intervention period. Several measures of productivity indicated that the intervention was effective in improving production, especially for employees with full annual workloads. Percentage of salaries earned in incentives was comparable for both the baseline and intervention periods. Possible explanations for trends in the data, weaknesses in the plan, and implications for future research are also discussed.

An Evaluation of the Effects of an Abridged Parent Training Program on Parent-child Interactions in the Home

Description: This study examined the effects of a condensed parent training program on parent-child interactions in the home. Two parents participated in a positive parenting workshop that included explicit training of four skills and indirect training of two additional skills. To determine skill acquisition, both parents performed role plays and completed written exams pre- and post-training. Role play assessment results showed improvements in all skill areas for both participants. Written assessment results showed improvements for all skills directly taught except one. Multiple measures were examined in the home prior to and following the workshop to assess generalization. Results showed an increase in positive interactions and decrease in coercive interactions and undesirable child behavior for both participants.

An Evaluation of the Effects of Two Different Role Play Formats on the Outcomes of a Parent Training Curriculum

Description: The current study was designed to replicate and extend previous research on the effectiveness of behavioral parent training. Specifically, the effectiveness of the Behavior Management and Parenting Services (BMAPS) curriculum in teaching parents to exhibit a set of parenting skills and respond accurately to a multiple choice examination about positive parenting techniques was evaluated. In addition, the curriculum was revised so that the relative effectiveness and acceptability of two role play formats could be assessed. The outcomes of the study showed an improvement in the participants' ability to identify correct answers on a multiple choice examination and apply the parenting skills taught in class within a role play format; results pertaining to the efficacy of each role play format were less conclusive.

An Evaluation of the Esthetic Judgment of Students in Austin College

Description: For the average person many opportunities for esthetic enjoyment of useful objects exist if the relationship between beauty and utility is understood. Furniture and other articles of daily use have acquired new and radical changes of design, based on function, which are altering esthetic concepts. This new approach to design is gradually being accepted by manufacturers and producers. Do purchasers appreciate and accept these structural and functional bases of contemporary design? If they do not, wherein does their deficiency lie, and how may it be corrected? This is the problem that the writer has attempted to investigate through this study.
