This study concentrates on the social status of women in one southern town during the late nineteenth century and the Progressive Era.

Two years before impoundment, the trophic status of Lake Ray Roberts was predicted by applying the total phosphorus input into the Organization for Economic Cooperation and Development (OECD) eutrophication model. Predicted mean summer epilimnetic (MSE) chlorophyll a of Elm Fork arm, Isle duBois arm and Main Body were in the eutrophic category of the OECD model. Observed MSE chlorophyll a two years after impoundment of Elm Fork arm, Isle duBois and Main Body had not reached their predicted means and were at the mesotrophic-eutrophic boundary of the OECD model. Six years after impoundment, observed MSE chlorophyll a for Main Body, was closer to its predicted mean and in the eutrophic category of the OECD model. Six years after impoundment, Elm Fork arm was the most productive area of Lake Ray Roberts. Observed means of chlorophyll a, total phosphates, suspended solids and turbidity were often highest in the Elm Fork arm. Wastewater effluent from Gainesville and Valley View, TX, had an impact on productivity in Elm Fork arm.

This study examined success rates and end-of-semester grades for three instructional methods used in developmental algebra and college algebra. The methods investigated were traditional lecture, laboratory, and computer mediated learning. The population included the 10,095 students who had enrolled in developmental algebra and college algebra at Richland College in Dallas, Texas, for five semesters. Success was defined as earning a grade of A, B, C, or D in a course.

The purpose of this study was to examine district level financial data to assess equity across districts, to compare equity benchmarks established in the literature using selected functions from the state's financial database, and to determine the predictive value of those functions to the Texas Assessment of Academic Skills (TAAS) tests of 1997.

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.

Throughout the United States, colleges and universities are faced with an increasing need for financial funding, while at the same time resources continue to diminish. With the limitations of available funds, community colleges must exhibit efficiencies in the operations of their institutions. External interests, such as governing boards and legislatures, require demonstration of efficient financial management. This evidence is then used to make decisions concerning future financial support for the community college. This study determined if community college chief executive officers use financial performance indicators as provided by the State Auditor's Office and if the chief executive officers of the community colleges value the compilation and the distribution of the financial performance indicators. In the selected colleges, many of the chief executive officers depend on their chief financial officer for understanding and application of financial performance indicators. The performance indicators distributed by the Auditor's Office captured only a snapshot of the college's performance, and failed to fully describe the whole college performance or specific financial events captured by the indicators. Though the indicators had flaws, either through incorrect data or lack of explanation, the CEOs did value their compilation because they provided a means for ‘getting the community college story' …

This study examined the status of women in Texas from 1860 to 1920. Age, family structure and composition, occupation, educational level, places of birth, wealth, and geographical persistence are used as the measurements of status. For purposes of analysis, women are grouped according to whether they were married, widowed, divorced, or single.

Little scholarship has been dedicated to nineteenth-century Texas family life and no published scholarship to date has addressed the more specific topic of divorce. This study attempts to fill that gap in the historiography through a quantitative analysis of 373 divorce actions filed in Washington and Harrison Counties. The findings show a high degree of equity between men and women in court decisions granting divorces, and in property division and custody rulings. Texas women enjoyed a relatively high degree of legal and personal autonomy, which can be attributed, in part, to a property-rights heritage from Spanish civil law.

This research sought to determine what relationship exists between time-on-task in computer-aided instruction (CAI) using Destinations courseware and progress in reading ability of developmental reading students as indicated by the reading portion of the Texas Academic Skills Program (TASP) test. Time-on-task is the time during which a student actively works on Destinations activities, as recorded by the software management system. TASP, an exam required of all students in Texas public colleges, assesses reading, math, and writing skills. The population was made up of 482 students who took the TASP exam before and after CAI and who used Destinations CAI for remediation of reading skills. Null hypotheses were explored using Pearson correlation and linear multiple regression. The findings for the null hypotheses were the following: Ho1 - Correlation and linear regression correlation showed that time-on-task in Destinations CAI had no significant effect on the TASP scores of the population studied. Ho2 - Correlation and linear regression correlation showed that females made significantly better gains on the TASP test from CAI than males. Ho3 - Correlation and linear regression correlation showed that low-achiever students made no better gains on the TASP test from time-on-task in CAI than high-achiever students. Difference between the …

An examination of the effectiveness of seeding, burning, and mowing in the reestablishment of tallgrass prairie species on overgrazed and abandoned pastureland. The study site is a 20 acre tract on U.S. Corps of Engineers land below Lake Lewisville in Denton County, Texas. The site was partitioned into thirty-nine 40 by 40 meter plots with seeding (carried out in 1996) and management treatment (burning, mowing, and no maintenance carried out in 1998) randomly applied following a two level design. For each plot, nine stratified-random 0.1 m2 subplots were examined and shoot counts for each species recorded. The effects of the treatments on individual species and species richness were analyzed with a two-way ANOVA followed by a SNK multiple range test, both on ranked data. Community level analysis was conducted with both a MANOVA on ranked data and a Canonical Correspondence Analysis on raw data. Results indicate that seeding positively affected species richness, particularly when combined with either burning or mowing in the early spring. Mowing also significantly increased species richness in areas that were not seeded, while burning negatively affected species richness on unseeded plots. Treatments significantly affected community composition with treatments having the most clear effect on spring and …

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.

The purpose of this study was to describe a Title I inclusion program in a north Texas middle school, to evaluate the degree of its success as a high achieving program, and to analyze how closely it met the requirements of the Improving America's Schools Act of 1994. Data were collected from the learning facilitators and teachers at the middle school with the permission of the school district. This study began with extensive research on the nature of adolescents and the beliefs and characteristics of high achieving middle schools. It addressed the steps which were recommended in the literature to improve middle schools and benefit students that are at-risk of failing to master the curriculum at their grade level. The researcher concluded by reporting effective strategies being used in middle school at-risk programs. These are strategies noted by experts as successful in identified programs. The population for this study was seventh and eighth grade Title I students who attended middle school during the 1992-1993, 1993-1994, 1994-1995 and 1995-1996 school years. The data collected by the researcher are presented in two parts: the description of the Title I inclusion program; and the results of the Texas Assessment of Academic Skills tests …

This study conducts watershed analysis using biological and geo-spatial techniques. Incorporating landscape features with biological attributes has been shown to be an effective method of monitoring environmental quality within watersheds. In situ biomonitoring using the Asiatic Clam, Corbicula fluminea, habitat suitability, and water quality data were evaluated for their potential to describe ecological conditions in agricultural and urban areas within the Upper Trinity River watershed. These data were analyzed with GIS to identify effects of land use on ecological conditions. C. fluminea downstream of point source effluents was effective detecting in-stream toxicity. Ambient toxicity appears to have improved in the Trinity, although urban influences limit aspects of aquatic life. No association between habitat quality and land use was identified.

This research study investigated the effectiveness of the application of child-centered play therapy procedures and skills by trained fifth grade students in play sessions with kindergarten children who had adjustment difficulties. Specifically, this research determined if play sessions with trained fifth grade students facilitated change in kindergarten children's self concept, internalizing behavior, and externalizing behavior and their parents' stress level.

This study focuses on the development of water resources in the Trinity River basin for navigation, flood control, water supply, recreation, and allied purposes. Special emphasis is given to the development of the upper Trinity River basin through the influence of community leaders in Dallas and Fort Worth. A desire harbored for generations by upper basin residents for creating a navigable waterway on the Trinity River coalesced in the twentieth century into a well organized movement for all facets of water resources development. Sources include correspondence, speeches, and promotional materials of civic leaders, politicians, and other citizens, as well as works by the United States Army Corps of Engineers.

Hygrophila polysperma is a plant native to Asia that has been introduced into the Comal River, TX and is thriving while Ludwigia repens, a species native to the river appears to be declining. Both plants have similar morphologies and occupy similar habitats in the river. Two plant competition experiments were conducted to examine the competitive interactions between the two species. First, an experimental design was developed in which established Ludwigia plants were 'invaded' by sprigs of Hygrophila to determine if established Ludwigia populations would be negatively impacted by invasion. The second experiment focused on establishment and growth of sprigs of each species under three competition scenarios. Results show that the continued growth of well-established Ludwigia plants was significantly depressed by the invasion of Hygrophila in comparison with those that had not been invaded. Furthermore, the growth of Hygrophila sprigs was uninhibited by the presence of Ludwigia, but the presence of Hygrophila negatively impacted the growth of Ludwigia sprigs. There was no difference in the growth of Hygrophila sprigs whether planted alone, with Ludwigia sprigs or even if planted into stands of established Ludwigia.

In an attempt to determine the effectiveness of a pretreatment assessment procedure known as the scatter plot (Touchette, MacDonald, & Langer, 1985), direct observational data was collected by 13 middle school teachers on four "problem" students. After four weeks of data collection, interobserver agreement probes were calculated and a visual analysis of the plotted data was performed to ascertain a possible pattern of problem behavior. Additionally, in an attempt to assess the teachers' perceptions of the scatter plot, the 13 teachers were asked to complete a questionnaire. Although a visual analysis of the plotted data suggested a possible pattern of problem behavior, interobserver agreement probes failed to achieve a desired overall reliability of 90% or higher. Despite a low IOA, results of the questionnaire administered to the 13 teachers generally supported the use of the scatter plot as a means of assessing student behavior. Possible reasons for failing to attain an IOA of 90% or higher include the total number of students in a class, the number of subjects observed per period, the teacher's location in the classroom, and the subjects ability to recognize if the teacher was "looking." Recommendations are provided regarding future research concerning the scatter plot and …

Stoney Burns (Brent LaSalle Stein) edited and published Dallas Notes, a Dallas, Texas, underground newspaper, from November 1967 through September 1970. This thesis considers whether Burns was the unifying figure in the Dallas counterculture.

This utilized identification theory to determine if faculty identify with the university and recognize its mission. The study also explored how faculty differentiate between a traditional university and a metropolitan research university. Finally, the study explored whether the faculty consider the University of North Texas to be a Metropolitan Research University. UNT full-time faculty members (N=224) completed questionnaires to indicate their identification with the university and their recognition of the university mission. Analysis showed that faculty have not come to a consensus on the definition of a MRU and that they do not identify with UNT.

Student retention is one of the most important issues facing higher education. The demand for accountability of higher education has pushed the issue of student retention to the forefront of its agenda. Increasingly, state legislatures are tying funding to institutional effectiveness, using graduation rates as measures of academic quality. Though there is an abundance of literature of studies conducted at the four year institution, few studies have examined the community college student. This study attempted to identify 4 specific pre-enrollment variables, (1) parent's education, (2) high school senior grade point average, (3) educational goals and (4) racial origin, as predictors of persistence and retention. The sample included 312 entering freshmen at North Lake College in Irving, Texas who were administered the College Student Inventory (CSI) in the fall semesters of 1995 and 1996. The 1995 cohort consisted of 201 entries, 103 (51.2%) female and 98 (48.8) male. The 1996 cohort consisted of 111 entries, 65 (58.5%) female and 46 (41.5%) male. A data base was constructed by extracting selected data elements from the completed inventory. Each student was tracked for one year following the semester they completed the survey. The Pearson Chi-Square Test of Independence with .05 level of significance …

The purpose of this study was to compare three different types of programming options for identified gifted and talented middle school students.

This study examined the effects of replicating woodland soil surface horizonation on the nutrient status of underlying soils and the initial establishment and growth of trees. A total of 283 container grown trees were planted in a bufferzone around a future landfill site. Control amendments consisted of an 8 cm layer (0.5 m3) of wood chips applied in a circular area of 4.6 m2 around the trees' planting pit. For the treatment, a 2.5 cm layer of composted biosolids (0.15 m3 or 80 Mg/ha) was applied in a circular area of 4.6 m2 around the trees' planting pit followed by an 8 cm layer (0.5 m3) of wood chips. The results indicate that the replication of woodland soil surface attributes using composted biosolids can significantly improve the nutrient status of underlying soil. Some significant effects were seen under control conditions, too. However, the effects on tree establishment and growth parameters were, for the most part, not statistically significant.

Utilizing a sample of community-residing older adults, this pretest-posttest design evaluated the short term (approximately 1 week) impact on everyday functioning of Stress Inoculation (SI) training, a cognitive-behavioral intervention that is essentially a coping skills enhancement program. The targets of training were anxiety and concern about being able to successfully perform everyday living tasks. The training program was contrasted with a no contact (waiting list) control. In an effort to maximize the practical aspects of this study, the assessment battery included the use of two ecologically valid measures of everyday problem solving skills (one self-rated and one interviewer-rated). Also included were a measure of everyday intelligence widely used in gerontological research, two measures of self-efficacy, a geriatric depression scale, a state-trait anxiety scale, and a self-report measure of failures in perception, memory, and motor function. The results suggest that Stress Inoculation training is an effective intervention for improving everyday competence but that personal perceptions of self-efficacy and the emotional states of anxiety and depression mediate treatment effects. In general, only persons with lower levels of self-efficacy and higher levels of anxiety and/or depression saw improvement in their cognitive performance following SI training.

The south-central United States serves as an important biogeographical link and dispersal corridor between Nearctic and Neotropical elements of western hemisphere odonate faunas. Its species are reasonably well known because of substantial collections, but there has been no concerted effort to document the extent of biodiversity and possible geographic affinities of dragonflies and damselflies of this region. The recent discoveries of Argia leonorae Garrison, Gomphus gonzalezi Dunkle and Erpetogomphus heterodon Garrison from southern and western Texas and northern Mexico suggest that Odonata species remain to be discovered in this area, particularly from far south Texas and northern Mexico. I have documented a total of 12,515 records of Odonata found in 408 counties within the south-central U.S. A total of 73 species of damselflies and 160 species of dragonflies was revealed in the region. The 233 (197 in Texas) Odonata species are distributed among 10 families and 66 genera. Illustrated family, generic, and species-level keys are provided. Since the beginning of this work in the Fall of 1993, one species has been added each to the Louisiana and Oklahoma faunas, and 12 species have been added, previously unreported from Texas, including four new to the U.S. The area of highest Odonata …
