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.

An Assessment of the Use of Seeding, Mowing, and Burning in the Restoration of an Oldfield to Tallgrass Prairie in Lewisville, Texas (open access)

An Assessment of the Use of Seeding, Mowing, and Burning in the Restoration of an Oldfield to Tallgrass Prairie in Lewisville, Texas

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 …

A Qualitative Study of the Use and Value of Financial Performance Indicators in Selected Community Colleges in the State of Texas as Perceived by their Chief Executive Officers

Access: Use of this item is restricted to the UNT Community
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' …

The Relationship Between Time-On-Task in Computer-Aided Instruction and the Progress of Developmental Reading Students at the University of Texas at Brownsville and Texas Southmost College (open access)

The Relationship Between Time-On-Task in Computer-Aided Instruction and the Progress of Developmental Reading Students at the University of Texas at Brownsville and Texas Southmost College

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.

Assessing the Spatial and Temporal Distribution of MTBE and BTEX Compounds in Lake Lewisville, Texas February 1999 - February 2000 (open access)

Assessing the Spatial and Temporal Distribution of MTBE and BTEX Compounds in Lake Lewisville, Texas February 1999 - February 2000

The spatial and temporal distribution of Methyl Tertiary-Butyl Ether (MTBE) and BTEX (Benzene, Toluene, Ethylbenzene, Xylenes) compounds were assessed in a multipurpose reservoir, Lake Lewisville, Texas between February 1999 and February 2000. Concentrations of MTBE ranged from 0.0 - 16.7 mg/L. Levels of MTBE in the lake were related to watercraft. BTEX concentrations were never detected above 2.0 mg/L during the sampling period. Finished drinking water from Denton and the Upper Trinity Regional Water District (UTRWD) Treatment Plants were also tested for MTBE and BTEX. MTBE and BTEX were not detected in UTRWD water samples. Denton's finished water samples never exceeded 2.2 mg/L for MTBE and BTEX was not detected except for one replicate of 1.1 mg/L toluene.

Characterizing the Municipal Solid Waste Stream in Denton, Texas

Access: Use of this item is restricted to the UNT Community
Forty-two commercially collected dumpsters from Denton’s Municipal Solid Waste Stream were emptied, sorted and weighed to characterize the material types and make preliminary recycling policy recommendations. The general composition of Denton’s solid waste stream was not significantly different from the composition of the nation’s solid waste stream. Fifty-eight percent of the observed waste stream was recyclable. Paper made up the largest portion of recyclable materials and the "grocery" source category had more paper than any of the other five categories. Based on these findings, an incrementally aggressive approach is recommended to reduce certain types of wastes observed in the waste stream. This would include a Pay-As-You-Throw Program followed by an Intermediate Processing Center that can be converted to a Materials Recovery Facility.

Life History and Case Building Behaviors of Phylloicus ornatus (Banks) (Trichoptera: Calamoceratidae) In Two Spring Fed Tributaries in the Central Edwards Plateau Bioregion of Texas

Access: Use of this item is restricted to the UNT Community
The life history and case-making behaviors of Phylloicus ornatus from two springfed first order streams in the Edwards Plateau Bioregion of Texas were studied from January 1998 to November 1999. Field larval, pupal and adult samples and laboratory rearings indicated a multivoltine cycle. First instars differ from late instars in number of labral setae and in having a unique spur-like claw on each lateral hump. Larval development was asynchronous with second through fifth instars and pupae present most months. First instars were present April through July, October and November. Case making of first instar and case reconstruction of later instars extracted from their cases was documented by videophotography.

Recovery of the Fish Population of a Municipal Wastewater Dominated, North Texas Creek After a Major Chlorine Disturbance (open access)

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.

Characteristics of Community Service Programs and Probationers in Texas (open access)

Characteristics of Community Service Programs and Probationers in Texas

As a criminal sanction, community service involves unpaid labor on the part of convicted criminal offenders. Community service was created as an alternative to incarceration for low-level offenders. It now appears, however, that community service is rarely used as a true alternative to prison, but rather as an added condition of probation. The body of research on community service in the United States is modest, so relatively little is known about its characteristics and administration. Data were attained from 88 Texas probation professionals via self-administered written surveys in an effort to gather information about the use of community service as a criminal sanction in Texas. Frequency distribution analyses identified characteristics of both community service programs and offender participants in Texas.

Contextualizing the Law: Sentencing Decisions of Sexual Assault Cases of Dallas County, 1999-2005 (open access)

Contextualizing the Law: Sentencing Decisions of Sexual Assault Cases of Dallas County, 1999-2005

The incidence of sexual assault inundates the courts with many cases each year. Given the unique nature of the crime, judges and juries are faced with an array of different scenarios to which they are required to make fair, justifiable and consistent decisions. I examine child sexual assault cases of Dallas County 1999-2005, I look at both legal and extralegal factors including case characteristics, institutional characteristics and characteristics of the defendants and the victims. First, I examine the impact of the independent variables on sentence length using regression analysis to determine influences on sentencing for judges and juries. Second, I examine the same factors using Probit analysis to determine which characteristics make a life sentence more probable for those decision-makers.

Hydrological Impacts of Urbanization: White Rock Creek, Dallas Texas (open access)

Hydrological Impacts of Urbanization: White Rock Creek, Dallas Texas

This research project concerns changes in hydrology resulting from urbanization of the upper sub-basin of the White Rock Creek Watershed in Collin and Dallas Counties, Texas. The objectives of this study are: to calculate the percent watershed urbanized for the period of 1961 through 1968 and the period of 2000 through 2005; to derive a 1960s average unit hydrograph and a 2000s average unit hydrograph; and, to use the two averaged hydrographs to develop a range of hypothetical storm scenarios to evaluate how the storm response of the watershed has changed between these two periods. Results of this study show that stormflow occurs under lower intensity precipitation in the post-urbanized period and that stormflow peaks and volumes are substantially larger compared to the pre-urbanized period. It is concluded that changes in watershed surface conditions resulting from urbanization have lowered the precipitation-intensity threshold that must be surpassed before storm run-off is generated.

What Went Wrong?  How Arrogant Ignorance and Cultural Misconceptions Turned Deadly at the San Antonio Courthouse, March 19, 1840 (open access)

What Went Wrong? How Arrogant Ignorance and Cultural Misconceptions Turned Deadly at the San Antonio Courthouse, March 19, 1840

Although the Council House Fight is well written about in the annals of early Texas history, this all-encompassing study will reveal a whole new picture. Unlike previous works that maintained one point of view, multiple perspectives were analyzed and explored to allow a more comprehensive view of the Council House Fight to emerge. Primary focus on social and cultural misunderstandings, as well as the mounting hostility between the Penateka Comanche and Texians across the frontier, will demonstrate their general distrust and hatred of the other. Detailing their complicated relationship will prove that neither the Texians nor the Comanche were without blame, and both shared responsibility for the deterioration of events on and before March 19, 1840.

Health Status and Access Disparities Among the Uninsured Working-Age Population in a Safety-Net Healthcare Network in Tarrant County, Texas

The objective of this research was to determine if healthcare access disparities exist across race and gender in a publically funded safety-net healthcare system in Texas. Data were examined from a representative random sample of 1468 adults aged 18-64 who were patients in this safety-net system in July and August of 2000 and were analyzed using binary logistic regression and chi-square measures of significance. Major Findings: On measures of health status - overall health rating (p =.051), limited employment (p =.000), energy level (p =.001), and worry (p =.012) - Anglos reported the worst health; Mexican Americans, the best health; with African Americans intermediate. Mexican Americans were more likely to have never had health insurance, and to also have had insurance in the past year; Anglos were least likely to have ever had insurance (p =.015) or to have had insurance in the past year (p =.000). On use of EDs (p =.028), problems getting prescription medicines (p =.029), and foregoing other necessities of life to pay for healthcare, Mexican Americans were least disadvantaged with African Americans reporting greatest use of EDs among both men and women, and Anglos the most problems with prescription medicines and foregoing care, especially among …

Funding and Effectiveness of Staff Development Programs in Three North Texas School Districts (open access)

Funding and Effectiveness of Staff Development Programs in Three North Texas School Districts

This dissertation study focused on three aspects of staff development in North Texas: 1) funding sources, 2) types of professional learning programs, and 3) teachers' views of the effectiveness of the funded programs. Qualitative data came from interviews with nine district administrators concerning funding sources and how those resources enhanced teacher skills. Quantitative data came from 1,277 responses from teachers regarding their background and perceptions about staff development. Data from interviews with district administrators were diagrammed to depict elements of funding staff development and to reveal how resources were used to plan, implement, and evaluate staff learning. An analysis of interview data revealed that availability of grants, property tax rates, and student enrollment affected how districts funded staff development. Administrators reported that districts funded professional learning that was planned according to academic initiatives, met the needs of adult learners, and adapted to the changing needs of school communities. Both administrators and practitioners reported that time was a lacking resource critical to developing staff knowledge. Practitioners reported that sufficient opportunity to collaborate with colleagues about learning initiatives was more valuable than teaching materials. Teacher questionnaires were analyzed for possible relationships between participant variables and responses concerning knowledge about funding constraints and …

County Level Population Estimation Using Knowledge-Based Image Classification and Regression Models (open access)

County Level Population Estimation Using Knowledge-Based Image Classification and Regression Models

This paper presents methods and results of county-level population estimation using Landsat Thematic Mapper (TM) images of Denton County and Collin County in Texas. Landsat TM images acquired in March 2000 were classified into residential and non-residential classes using maximum likelihood classification and knowledge-based classification methods. Accuracy assessment results from the classified image produced using knowledge-based classification and traditional supervised classification (maximum likelihood classification) methods suggest that knowledge-based classification is more effective than traditional supervised classification methods. Furthermore, using randomly selected samples of census block groups, ordinary least squares (OLS) and geographically weighted regression (GWR) models were created for total population estimation. The overall accuracy of the models is over 96% at the county level. The results also suggest that underestimation normally occurs in block groups with high population density, whereas overestimation occurs in block groups with low population density.
