Post-Traumatic Symptomatology in the Luby's Shooting (open access)

Post-Traumatic Symptomatology in the Luby's Shooting

The role of exposure to a human-made disaster and the subsequent development of post-traumatic stress reactions were examined. Subjects included 49 males and 30 females who were variously exposed to the Luby's shooting incident in Killeen, Texas in October of 1991. Post-traumatic stress symptomatology was measured by the SCL-90R. Exposure was operationalized by using a scenario-rating scheme with independent raters estimating each subject's level of exposure. A regression and commonality analysis revealed that exposure is an important predictor in post-traumatic symptomatology. Premorbid functioning and gender were also found to play important roles, with females expressing higher levels of symptomatology.

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.

Hooking Mortality of Largemouth Bass Caught on Controversial Artificial Lures and Live Bait : Lake Ray Roberts, Texas (open access)

Hooking Mortality of Largemouth Bass Caught on Controversial Artificial Lures and Live Bait : Lake Ray Roberts, Texas

A total of 192 largemouth bass were caught at Lake Ray Roberts, Texas (1995) to investigate five controversial bass angling techniques relative to hooking mortality. The bait types were Texas-rigged scented and non-scented plastic worms, Carolina-rigged scented and non-scented plastic worms, and live golden shiners. Overall hooking mortality was 21.87% and mortality was dependent upon bait type. Highest mortality resulted from the Texas-rigged scented lures, while the lowest mortality was generated by live golden shiners. A creel survey indicated that few anglers were having success with the investigated baits. Factors that had a confirmed effect on hooking mortality were hooking location and water temperature. Hooking mortality was not excessive compared to other similar studies.

Progressivism/Prohibition and War: Texas, 1914-1918 (open access)

Progressivism/Prohibition and War: Texas, 1914-1918

This thesis focuses upon the impact of war upon the progressive movement in Texas during 1914-1918. Chapter I defines progressivism in Texas and presents an overview of the political situation in the state as relating to the period. Chapter II discusses the negative impact that the first two years of World War I had upon the reform movement. Chapter III examines the revival of the Anti-Saloon League and the 1916 Democratic state convention. Chapter IV covers the war between James E. Ferguson and the University of Texas. Chapter V tells how the European war became a catalyst for the reform movement in Texas following America's entry, and its subsequent influence upon the election of 1918. Chapter VI concludes that James E. Ferguson's war with the University of Texas as well as World War I were responsible for the prohibitionist victory in the election of 1918.

Evaluation of a Constructed Wetland to Reduce Toxicity from Diazinon at the Pecan Creek Wastewater Treatment Plant, Denton, TX (open access)

Evaluation of a Constructed Wetland to Reduce Toxicity from Diazinon at the Pecan Creek Wastewater Treatment Plant, Denton, TX

The City of Denton Pecan Creek Wastewater Treatment Facility has periodically failed effluent toxicity testing. A Toxicity Identification Evaluation has determined that Diazinon in the effluent is contributing to the observed toxicity. Chlorpyrifos is also implicated as a factor. The City of Denton constructed a half acre experimental wetland to remove Diazinon related toxicity. Results from spiking and microcosm experiments indicate that the wetland can reduce the Diazinon.

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 Use of Similarity Indicies to Assess the Spatial Differences of the Phytoplankton Communities in Lake Ray Roberts, Texas (open access)

The Use of Similarity Indicies to Assess the Spatial Differences of the Phytoplankton Communities in Lake Ray Roberts, Texas

A study of the phytoplankton communities of Lake Ray Roberts was conducted at three sampling sites on two sampling dates during the summer of 1995, assessing both community structure and chlorophyll a concentrations. Eight similarity indices were then used to characterize and compare the communities of these sites. Both community similarity and chlorophyll a concentrations were evaluated using a minimum detectable difference equation to determine the amount of change that must occur in these parameters in order to be deemed statistically significant. The Bray-Curtis Index was shown to be the most adequate index evaluated, and was subsequently used in conjunction with bootstrap analysis to determine the similarity between the three sampling sites.

Evaluating Fish Impingement and Entrainment at the Comanche Peak Steam Electric Station (open access)

Evaluating Fish Impingement and Entrainment at the Comanche Peak Steam Electric Station

This study was designed to determine if impingement and entrainment by cooling water intake at the Comanche Peak Steam Electric Station have an adverse impact upon the Squaw Creek Reservoir fish population. The yearly impingement of fish was estimated to be 262,994 of 14 species. The threadfin shad (Dorosoma petenense) accounted for 96% of this total. Entrainment of eggs and larvae for a five month period was estimated to be 15,989,987 and 42,448,794 respectively. Two fish population studies were performed on Squaw Creek Reservoir to help assess impact. It was determined that the losses due to impingement and entrainment have no adverse impact upon the fish population of Squaw Creek Reservoir.

An Investigation of the Influence of Evaluator Background on Appraisals of a Music Lesson Using the Texas Teacher Appraisal System

This study's purpose was to investigate the differences in scores and written comments given by two appraisal groups in their evaluation of a music teacher using the Texas Teacher Appraisal System (TTAS). One appraiser group had musical training while the other group specialized in other subjects. Analyses of both group's appraisal scores showed no significant differences. An examination of the written comments revealed that both appraisal groups focused on the same aspects of the lesson and used similar vocabulary. The TTAS instrument was a consistent measure of generic teacher behaviors in the music lesson, but it did not measure specific music teaching behaviors or encourage suggestions for improving musical instruction.

An Analysis of Refuse Derived Fuel as an Environmentally Acceptable Fuel Alternative for the Cement Industry (open access)

An Analysis of Refuse Derived Fuel as an Environmentally Acceptable Fuel Alternative for the Cement Industry

Resource recovery is an attractive alternative to the waste disposal problem. The chief by-product of this process, refuse derived fuel (RDF) can be co-fired in traditional coal burning facilities. The cement industry is a potential user of RDF. This study, based on a test burn done at Texas Industries Inc. in Midlothian, Texas, demonstrated the technical, environmental, and economic feasibility of using RDF fuel in a cement kiln. Technically, the cement showed no deleterious effects when RDF was substituted for coal/natural gas at 20% by Btu content. Environmentally, acid rain gases were reduced. Economically, RDF was shown to be a cost effective fuel substitute if a resource recovery facility was erected on site.

Class and Freedom of Choice in the Marriage Patterns of Antebellum Texas Women (open access)

Class and Freedom of Choice in the Marriage Patterns of Antebellum Texas Women

Little scholarly analysis has been devoted to the hypothesis that antebellum Texas women generally married within their own socioeconomic (slaveholding) class, and thus had only limited choice in the selection of marriage partners. This quantitatively based investigation suggests that the popular image should be carefully qualified. This study reveals that although a majority of Texas women who married during the early 1850s chose men who had the same slaveholding status, a significant minority crossed class lines. By using marriage records of the period in correlation with information gleaned from the census, conclusions were reached. Contemporary women's diaries, letters and reminiscences were investigated, in addition to a historiography of marriage in the South, which created the background for this study.

Nutrition Knowledge and Attitudes of Students in Four-Year Hospitality Programs (open access)

Nutrition Knowledge and Attitudes of Students in Four-Year Hospitality Programs

The purpose of this research was to determine the level of nutrition knowledge of students in four-year hospitality programs; their attitudes toward nutrition in general (general attitudes); and their attitudes toward its role in commercial foodservice (restaurant attitudes). Correlations between knowledge and attitudes and differences based on gender, age, college classification, and completion of a college nutrition course were also examined. Hospitality management majors in baccalaureate programs at three Texas universities completed 454 usable questionnaires. Although knowledge was not extensive, general and restaurant attitudes were positive. Knowledge was influenced by all factors except gender. General attitudes were influenced by gender, age, and classification. Only gender influenced restaurant attitudes. Knowledge was positively correlated with favorable attitudes.

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.

Anger/Hostility: Reliability of Measurement and Correlates of Health History

The purpose of this study was to (1) assess the reliability and validity of anger/hostility measures, (2) examine the relationship between anger/hostility and other negative emotions, and (3) examine the relationship between anger/hostility and health history. Sixty-five subjects were given the Buss Durkee Hostility Inventory (BDHI), the State-Trait Anger Expression Inventory (STAXI), the Profile of Mood States pomsS), the Clinical Analysis Questionnaire (CAQ), the State-Trait Anxiety Inventory (STAI), the Health and Wellness Attitude Inventory (HWAI), and a health questionnaire designed to provide information about past disease and alcohol/drug use. Overall, the BDHI and POMS displayed good test-retest reliability. All six of the global indices of anger/hostility intercorrelated at a significant level, thus demonstrating good concurrent validity. The six global measures of anger/hostility also correlated at a significant level with other negative emotions.

A Study of the Relationships among Teachers' Immediacy of Dress Factors and Affective Learning Factors: a Relational Communication Perspective (open access)

A Study of the Relationships among Teachers' Immediacy of Dress Factors and Affective Learning Factors: a Relational Communication Perspective

This thesis examined the relationships among immediacy of dress factors and affective learning factors as they pertain to relational communication. College students (N = 482) completed questionnaires indicating perceptions of selected nonverbal immediacy behaviors associated with their teacher's attire. The research predicted that there would be relationships between and among power and affinity of dress, dress immediacy and nonverbal immediacy. Further predictions were made concerning the associations among these variables, affective learning outcomes, and other teacher criteria. Analysis indicated that power of dress, affinity of dress and dress immediacy were viable nonverbal immediacy concepts which related to affective learning outcomes. Research findings indicated that certain instructor variables may also influence these relationships.

Second-Order Conditional Control of Members of an Equivalence Class

The conditional control of equivalence has received much attention in the analysis of verbal behavior. While previous research identified conditional control of relational responding and conditional control of equivalence class formation, this study investigated the possibility of conditional control of members of an equivalence class. Following baseline conditional discrimination training and equivalence testing, subjects were taught to select a particular member in the presence of a Green background screen and another member in the presence of a Red background screen.

Populism and the Poll Tax: the Politics and Propaganda of Suffrage Restriction in North Texas, 1892-1904 (open access)

Populism and the Poll Tax: the Politics and Propaganda of Suffrage Restriction in North Texas, 1892-1904

This thesis challenges the traditional interpretation of the history of Populism in America through the use of an intensive regional study. Using precinct-level returns, this thesis proves that, contrary to the conclusions of more general studies, voters from predominately Populist areas in North Texas did not support the poll tax amendment that passed in November 1902. The Populists within this region demonstrated their frustration and distrust of the political process by leaving the polls in higher percentages than other voters between 1896 and 1902. The Populists that did participate in 1902 reentered the Democratic Party but did not support the poll tax, which was a major plank within the Democratic platform. This thesis also proves that the poll tax had a significant effect in reducing the electorate in North Texas.

Assessing Defensiveness with the PAI: a Cross Validational Study

The use of scales on the Personality Assessment Inventory (PAI) to detect defensiveness in criminal and nonclinical samples was evaluated. Forty-five male inmates of a county jail and 38 male undergraduate psychology students were provided with incentives to complete the PAI under two conditions: standard instructions and experimental instructions to feign a specific, positive role. The sequence of instructions was counterbalanced in both samples for the purpose of examining ordering effects. A repeated measures multivariate analysis of variance (MANOVA) was performed, yielding significant main effects of condition, group and order. Additionally, a step-wise discriminant function analysis significantly predicted group membership (i.e., subjects under honest and faking conditions) with a hit rate = 84.4%. Finally, a more effective cutting score for the Positive Impression scale was recommended.
