Abraham Lincoln and the American Romantic Writers: Embodiment and Perpetuation of an Ideal
The American Romantic writers laid a broad foundation for the historic and heroic Abraham Lincoln who has evolved as our national myth. The writers were attracted to Lincoln by his eloquent expression of the body of ideals and beliefs they shared with him, especially the ideal of individual liberty and the belief that achievement of the ideal would bring about an amelioration of the human condition. The time, place and conditions in which they lived enhanced the attraction, and Lincoln's able leadership during the Civil War strengthened their estimation of him. His martyrdom was the catalyst which enabled the Romantic writers to lay the foundation of the Lincoln myth which has made his name synonymous with individual freedom everywhere even today.
Academic Achievement: Examining the Impact of Community Type at a Small Liberal Arts College in Texas
Hierarchical regression was used to determine if high school community type is an effective predictor of academic success when controlling for demographics, prior academic achievement, socioeconomic status, and current commitment or work habits for students entering Austin College in 1992,1993, and 1994 . Findings revealed that there is a relationship between attending high school in community types of rural and independent town controlling for the effects of SAT scores, high school rank, sex, and late application deposit on first semester grade point average.
The Activities of Disaster Relief Organizations During the Permanent Housing Phase of Recovery: a Case Study Analysis
This study investigates the recovery efforts provided for low income and ethnic minority populations by organizations during the permanent housing phase of recovery in Watsonville, California, following the Loma Prieta earthquake of October 17, 1989. The case study format is used to discover what activities were performed and why each organization chose to perform them. Dynes and Quarantelli's (1968) typology of organization is used to explain how and why established, expanding, extending and emergent organizations participated in the recovery efforts. The findings indicate that the type of organization dictated the kind of tasks each organization performed. Organizations maintained activities during recovery for which they had experience, expertise and proficiency.
Acts of Survival: the Plight and Prospects of Dallas Theatre
A comprehensive investigation examines the decline and changes that have affected Dallas regional theatre development from the dream of Margo Jones in the 1940s to the proliferation of emerging theatres in 1993. Changing economic conditions, lack of audience support, and shortages of performance space have contributed to an exodus of Dallas actors and artists. Reviewed are measures to reverse this trend, including funding changes, awareness campaigns, improved inter-theatre cooperation, and guidelines for audience development. The study's conclusion notes that theatres do, indeed, have a natural life cycle, but with renewed emphasis on audience development and self-sufficiency, theatres in Dallas can endure and contribute to an enlarged sense of civic pride.
Advising the ARVN: Lieutenant General Samuel T. Williams in Vietnam, 1955-1960
Beginning in 1954, the United States Army attempted to build a viable armed force in South Vietnam. Until the early 1960s, other areas commanded more American attention, yet this formative period was influential in later United States involvement in Vietnam. This thesis examines United States advisory efforts from 1955 to 1960 by analyzing the tenure of Lieutenant General Samuel T. Williams as Chief of the Military Assistance Advisory Group in South Vietnam. During Williams's tenure, the communist forces in the north began the guerrilla insurgency in earnest. Williams's failure to respond to this change has been justly criticized; yet his actions were reflective of the United States Army's attitude toward insurgencies in the late 1950s.
AIDS Preventative Behavior Among Taiwanese University Students
This study used the Health Belief Model to examine the predictors of AIDS preventive behavior. The independent variables were the variables of individual perception, modifying factors (psychological variables), and likelihood variables. The respondents, the Taiwanese students of the University of North Texas, were influenced both by Chinese sexuality and Western values in their AIDS-risk behavior. The results revealed that 90% of the respondents were misinformed on the availability of AIDS vaccine. In addition, a majority of the students were either abstaining from sex or practicing monogamy. Using Pearson's correlation coefficient and multiple regression analysis, this study found that the psychological variables rather than cognitive variables significantly influenced the respondents' AIDS preventive behavior. Finally, suggestions were made for future research on AIDS, and for AIDS preventive behavior campaigns.
Americans who did not wait: the American Legion of the Canadian Expeditionary Force, 1915-1917
This study examines the five American Legion battalions of the Canadian Expeditionary Force formed in 1915 specifically to recruit American volunteers for the Canadian overseas contingent of the First World War. This study reviews the organization of Canada's militia and Anglo-American relations before examining the formation of the American Legion, the background of its men, and the diplomatic repercussions it sparked. This study is based largely on material in the Public Archives of Canada including war records and the personal papers of several participants. During its brief existence, the American Legion precipitated constitutional, diplomatic, and political problems. The issues the American Legion raised were mostly solved by America's entry in the war. The episode hastened the maturity of Canada as a nation.
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.
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.
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 Appeal of Fashion Retailing as a Career: Perceptions of Fashion Merchandising Students
This study investigated the (1) relationship of students' family and educational background to their opinions of fashion retailing as a career, and (2) preferences for fashion retail job attributes in relationship the appeal of fashion retail job profiles. A sample of 131 fashion merchandising students from five state-funded universities completed a four-part survey which measured two independent variables: student background and preferences of fashion retail job attributes and two dependent variables: opinions of fashion of retailing as a career and the appeal of fashion retail job profiles. Analyses included multiple regression, t-test, and correlations. For opinions of fashion retailing as a career, parental background was not significant while attendance at a retailing course, semester hours completed and G.P.A. had limited relationships. Fashion retail job attribute preferences were related to the appeal of fashion retail job profiles; the most preferred attribute was high personal freedom.
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.
Assessing Regional Gully Erosion Risk: A Remote Sensing and Geographic Information Systems Approach
Gully erosion has been established as a major source of sediment pollution in the upper Trinity River watershed in north-central Texas. This fact, along with a lack of models appropriate for a large-area gully erosion analysis established a need for a gully erosion study in the upper Trinity basin. This thesis project attempted to address this need by deriving an index indicative of gully erosion risk using remote sensing and geographic information systems (GIS) methodology. In context of previous field studies, the coarse spatial resolution of the input GIS data layers presented a challenge to prediction of gully prone areas. However, the remote sensing/GIS approach was found to provide useful reconnaissance information on gully risk over large areas.
Assessing the Effects of a Municipal Wastewater Treatment Plant Effluent on Zooplankton, Phytoplankton and Corbicula Flumina in a Constructed Wetland
Wetland wastewater treatment offers low-cost, energy efficient alternatives to conventional wastewater technologies. In this study, an artificial wetland was constructed at the City of Denton, Texas Pecan Creek Water Reclamation Plant to facilitate diazinon removal from treated effluent.
Assessment of Changes in Aquatic Macrophyte Occurrence Following Introduction of Triploid Grass Carp in a North Texas Reservoir
The objectives of this project were to measure changes in frequency of occurrence of submerged macrophytes over the first two growing seasons following stocking with triploid grass carp at two fish per acre and to measure differences in macrophyte biomass between areas excluded from herbivory and adjacent control sites after 16 months following establishment of exclosures. The project also seeks to measure concentrations of fluridone following the herbicide treatment, and to compare two methods of aquatic vegetation sampling.
An Assessment of College Students' Attitudes and Empathy toward Rape
The purpose of this study was to assess rape attitudes and empathy levels of students at a university in North Texas. The Attitudes Toward Rape questionnaire and the Rape Empathy Scale were administered to 387 undergraduate students. Dependent variables were attitudes and empathy and independent variables were prior knowledge or experience as a rape victim, having female siblings, gender, marital status, and age. Significance was found between rape-intolerant attitudes and both prior experience as a victim (p < .001), and gender (p < .001). Significance was also found between empathy and experience as a rape victim (p < .035) and gender (p < .032).
Assessment of Radio-Tagged Grass Carp (Ctenopharnygodon idella) Dispersion, Vegetation, and Temperature Preferences in North Lake Reservoir
Twenty-nine (Group One, June 8,1995) grass carp (Ctenopharyngodon idella) and five (Group Two, April 18, 1996) grass carp were radio-tagged to monitor movement patterns and habitat preferences on North Lake, a 335 hectare multi-use reservoir located in Irving, Texas. Overall fish mean Average Daily Movement (ADM) rates were 49.2 meters/day (during Half One, 6/8/95-11/30/95) and 5.3 meters/day (during Half Two, 12/14/95-6/6/96). Aquatic macrophtye distribution data were obtained. Radio-tagged grass carp were located in Hydrilla verticillata infested areas increasingly throughout the study, however, percent frequency of Hydrilla along 15 transects did not decrease. Radio-transmitters were equipped with temperature-sensors (10-35 Celsius range). Results indicated that radio-tagged grass carp showed no avoidance of areas of North Lake with elevated water temperatures. Radio-tagged grass carp dispersed quickly from stocking point, then moved into littoral areas infested with Hydrilla. After an initial movement period, most fish remained in a localized area.
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.
Atmospheric Visibility Assessment for Urban Areas Using Photographic Slides and Optical Densitometry
The factors involved in calculating Standard Visual Range (SVR) are discussed, and a comparison is made between the visibility reported by airport observers and the photographic slide/ optical densitometer method of calculating SVR. Using slides of Houston, Texas, from the fall and winter of 1988-89, it was found that the altitude at which the contrast measurements are made significantly affects the SVR. Also an index for predicting high and low humidity was developed using the blue/red ratio of the log exposure of the sky, and sun/shade target condition.
An Attributional Analysis of the Causes Cited by Junior High School Band Directors for Success and Failure at U.I.L. Concert/Sightreading Contest and Their Attitudes Towards Contest
The reasons given by thirty-three junior high school band directors for success and failure at the University Interscholastic League Concert/Sightreading Contest were studied using the methodology of Attribution Theory. All of the subjects attended the same contest and were members of a region which included urban and suburban schools. The subjects responded to a questionnaire which evaluated their attitudes towards the contest, allowed them to make judgments about other directors in hypothetical contest situations, and finally asked them to list the five most important reasons for their success or failure at the contest in an open-response format.
"The Best Stuff Which the State Affords": a Portrait of the Fourteenth Texas Infantry in the Civil War
This study examines the social and economic characteristics of the men who joined the Confederate Fourteenth Texas Infantry Regiment during the Civil War and provides a narrative history of the regiment's wartime service. The men of the Fourteenth Infantry enlisted in 1862 and helped to turn back the Federal Red River Campaign in April 1864. In creating a portrait of these men, the author used traditional historical sources (letters, diaries, medical records, secondary narratives) as well as statistical data from the 1860 United States census, military service records, and state tax rolls. The thesis places the heretofore unknown story of the Fourteenth Texas Infantry within the overall body of Civil War historiography.
Billy and Me and Other Stories
The thesis begins with an introductory chapter that explains the problems that short story theorists encounter when they try to define the short story genre. Part of the problem results from the lack of a definition of the short story in the Aristotelian sense. A looser, less traditional definition of literary genres helps solve some of the problem. Six short stories follow the introduction. "Billy and Me," "Queen of Hearts," "The Whiskey Man," and "Psychedelic Trash Cans" are representative of traditional short stories. "Mourning Coffee" and "Seven X Seven" might very well fit into other genres, but even these stories fit a loose definition of the short story genre.
Biology and Energetics of Tropisternus Lateralis Nimbatus (SAY) (Coleoptera: Hydrophilidae) in a Playa on the Southern High Plains of Texas and Aquatic Coleoptera Diversity from Seven Playas on the Southern High Plains of Texas
A study of the biology of Tropisternus lateralis, a hydrophilid beetle, was conducted during the flood period of a single playa on the Southern High Plains of Texas from early June 1995 through early September 1995. Mechanism of colonization, tolerance/avoidance to drought, larval density, and secondary production were analyzed. T. lateralis colonized playas from surrounding aquatic habitats and avoided drought through aerial dispersion. Once in the playa, larval density increased over time. Secondary production was 1.31 g/m2/.25 yr. In addition, aquatic Coleoptera diversity was studied in seven playas on the Southern High Plains of Texas. A total of twenty three species were identified from the study region. Nine species not reported in playa literature were identified.
Black Nationalism Reinterpreted
Black nationalism responded to America's failure to examine the effects of slavery's legacy. Its aims represent those issues that were either unsupported by or in opposition to the goals of the civil rights leadership. In particular, the civil rights movement dismissed any claims that the history of slavery had a lasting effect on African-Americans. This conflict developed because of mainstream America's inability to realize that the black community is not monolithic and African-Americans were differentially affected by slavery's legacy. It is those blacks who are most affected by the culture of poverty created by America's history of slavery who make up today's inner-city populations. Despite successes by the civil rights movement, problems within lower-class black communities continue because the issues of the black underclass have not yet been fully addressed.
"The Buck Stops With Me" : An Analysis of Janet Reno's Defensive Discourse in Response to the Branch Davidian Crisis
This study provides a genre analysis of Janet Reno's apologia in response to the Mt. Carmel disaster. Discussions of the events leading up to the crisis, Reno's rhetorical response, and relevant situational constraints and exigencies are provided.
Bus Ride to Liberation: a Historical Video Documentary of the Acres Homes Transit Company in Houston, Texas
The Acres Homes Transit Company in Houston, Texas is Texas' first African American owned and operated bus company. Some say it is the first in the South. The company was developed during the height of the civil rights period. It serves as an establishment of economic empowerment during the oppressive civil rights era. The video is a historical visual documentation of the bus company from its beginning to its end. An accompanying written profile describes the research process, the pre-production, production and post-production stages, as well as future proposals for the documentary.
"But a Mournful Remedy": Divorce in Two Texas Counties, 1841-1880
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.
Callibaetis Floridanus (Ephemeroptera: Baetidae) Life History and Production in a West Texas Playa
A life history study of Callibaetis floridanus was conducted over the wet cycle of a playa on the Southern High Plains of Texas from June through September 1995.
The Causes of the American Civil War: Trends in Historical Interpretation, 1950-1976
This thesis examines the trends in historical interpretation concerning the coming of the American Civil War. The main body of works examined were written between 1950 and 1976, beginning with Allan Nevins' Ordeal of the Union and concluding with David M. Potter's The Impending Crisis, 1848-1861. It also includes a brief survey of some works written after 1976. The main source for discovering the materials included were the bibliographies of both monographs and general histories published during and after the period 1950-1976. Also, perusal of the contents and book review sections of scholarly journals, in particular the Journal of Southern History and Civil War History, was helpful in discovering sources and placing works in a time chronology for the thesis narrative.
Characteristics of Texas Border and Non-Border Banks and a Comparison of their Lending Practices
This thesis presents a comparison of the loan to deposit ratios of Texas banks along the Mexican border and banks located throughout the rest of the state. Mean characteristics of the two groups (i.e. border and non-border groups) are presented. A multivariate regression model is used to examine the extent to which various operating ratios of the banks and differing economic conditions of the communities in which the banks are located help explain the loan to deposit ratios of the banks involved in this study. The model incorporates data from 1984-1989. No evidence was found to refute the hypothesis that Texas border banks have a lower loan to deposit ratio than their non-border counterparts. The evidence points to a need for developmental capital, supplied by some form of development bank.
Charles Beard versus the Founding Fathers: Property Concepts in the Eighteenth Century
This thesis deals with the role of property in the formation of the American Constitution and government. Charles Beard's views on property are compared with writings from the eighteenth century. Beard's writings on property and his critics are examined in the first two chapters. Then, the thesis's two historical contexts are evaluated. Concentrating on the Enclosure Acts, the fourth chapter looks at the importance of land to the former Englishmen. The eighteenth century view of property is the focus of the fifth section. The last chapter contrasts the two different views of property. Beard believed that the Constitution was a conservative document that protected the property of the few over the many. The Founding Fathers actually included liberal protections for property in the eighteenth century.
Children's Inferences Based on Brand Personality
This study explored the inferences male children held about the brand personality. The sample included 46 male fifth graders. Personal interviews were conducted and the results were compiled and interpreted using descriptive statistics. Four subject areas were addressed: identification and inferences about brand personality, sources of inferences, children's ability to make inferences about other children based on brand personality, and application of brand personality to self. Results indicated children make inferences about brand personality, make inferences about other children based on brand personality, and apply brand personality to themselves. An attempt to identify sources of inferences was inconclusive.
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.
College Students' Attitudes toward Pregnancy and Women in the Work Force
The purpose of this study was to assess college students' attitudes toward pregnancy and women in the work force following the passage of the Family Medical Leave Act of 1993. Data were obtained from 347 students at a university in North Texas during the spring semester of 1997. Gender, age, employment status, parental status, and citizenship were independent variables hypothesized to influence attitudes toward pregnant working women. Gender was significant for the following factors: pregnant women as employees (p<.001), emotional stereotypes (p<.001), choosing family or career (p<.001), and physical limitations (p<.001). Those students 17-19-years-old had a more negative attitude toward pregnant women choosing work over family (p<.001) than did the older students.
A Comparative Content Analysis of ITAR-TASS's and the United Press International's Coverage of the Russian Referendum in April 1993
A comparative content analysis was conducted to determine whether the Russian (ITAR-TASS) and the American (UPI) wire service coverage of President Boris Yeltsin in the April 25, 1993, referendum was balanced and unbiased. Also, the amount of space dedicated to this topic was measured. Study results indicate that ITAR-TASS was more critical of Yeltsin prior to the referendum than UPI, and that there was no statistically important difference between the two wire services in their post referendum coverage. UPI articles were almost 30% longer than the ITAR-TASS articles. Each UPI article was on an average more than 220 words longer than were the ITAR-TASS articles.

Comparing Quality of Life: American and Portuguese Cancer Patients with Hematological Malignancies
The purpose of this study is to investigate the differences and similarities of quality of life (QoL) in American and Portuguese cancer patients with hematological malignancies as well as the robustness of the measures cross-culturally. Portuguese participants were 98 patients and 49 accompanying persons and the American participants were 55 patients and 22 accompanying persons. Fifty (Portuguese sample) to 40% (American sample) of the patients came with an accompanying person who answered the questionnaire concerning the patient's QoL. The two cultural groups were characterized in terms of QoL (measured by the SF-36 and the FLIC), social support (Social Support Scale), socio-demographic and clinical variables. Portuguese patients reported a higher QoL. However, this result could be attributable to the fact that the two cultural samples differ in socio-economic status. The measures seem to be comparable for the Portuguese and American samples, at least in what concerns reliability and concurrent validity.
A Comparison between the Self-concept of Visually-impaired Adults and Sighted Adults
Self-concept scores of 19 visually-impaired adults were compared to those of 19 matched sighted adults using the Tennessee Self-Concept Scale (TSCS). All participants attended the University of North Texas. Scores were examined against the Vocabulary and Information subtests of the Wechsler Adult Intelligence Scale-Revised (WAIS-R).
A Comparison of Points Versus Sounds as Reinforces in Human Operant Research
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.
A Comparison of Predicted and Actual Trophic Status of Lake Ray Roberts, Texas Based on Chlorophyll A
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.
Comparison of Visual and Auditory Continuous Performance Tests in Adults
Two continuous performance tests were administered to normal adult subjects. The mode of presentation (visual or auditory) and the type of task (vigilance or distractibility) were varied, and their effects on performance measured. Data were collected on eighty-two subjects, and results indicated that auditory presentation of stimuli increased the difficulty of both tasks. Results also suggest that the distractibility task administered in either mode was more difficult than the vigilance task. Intercorrelations among the four continuous performance tasks are provided. Normative data are presented on all four tasks administered. A measure of symptoms of attention-deficit disorder in adults, the Adult Behavior Checklist, was found to correlate significantly with another measure of pathology, the SCL-90-R.
Conception and Design of Constructed Wetland Systems to Treat Wastewater at the Biosphere 2 Center with Use of Reaction Rate Models and the Habitat Evaluation Procedure to Determine the Effects of Designing for Wildlife Habitat on Treatment Efficiency
A study was undertaken to explore relationships between wetland characteristics which make them efficient water purifiers versus their ability to serve as wildlife habitat. The effects of designing constructed wetlands for improved habitat on water treatment efficiencies were quantified. Results indicate that some sacrifice in treatment efficiency is required and that the degree of efficiency reduction is dependant upon pollutant loading rates. However, sacrifice in efficiency is much smaller than increase in habitat quality, and can be offset by increasing wetland area. A practical, theoretical application was then attempted.
A Construct Validation Study of the Personality Inventory for Youth (PIY) Using an Incarcerated Juvenile Population
The Personality Inventory for Youth (PIY) is a recently developed, multiscale assessment instrument designed specifically for adolescents between the ages of nine and 18. The purpose of this archival study was to establish clinical correlates for the PIY scales. PIY profiles were collected from 100 juvenile files at the Gainesville State School and examined in conjunction with the Child Assessment Scale (CAS) and the Personal Attitude Scale (PAS) to provide evidence of convergent and discriminant validity. Results indicate modest to moderate convergent validity according to Campbell and Fiske's criteria for construct validity; however, discriminant results indicate considerable overlap among traits which are not expected to be highly correlated.
Contemporary Biology Curriculum for Non-majors
The proposed biology curriculum for non-majors has one main objective, namely to improve scientific literacy among college students. The National Science Education Standards defines scientific literacy as "the knowledge and understanding of scientific concepts and processes required for personal decision making, participation in civic and cultural affairs, and economic productivity". The suggested strategies to accomplish this goal are to limit the number of topics covered, introduce relevant scientific terminology, emphasize general biological concepts and themes, and hone critical thinking and problem-solving skills. Activities such as group projects, written and oral assignments, and class discussions are effective tools to assess student ability to communicate scientifically. It is also important for students to make connections between the course subject matter and how it affects real life events.
A Critical Examination and Analysis of Differences in Perceived Levels of Marital Satisfaction among Nigerian Couples in the Dallas-Fort Worth Area
The purpose of this investigation was to critically examine differences in the perceived levels of marital satisfaction among Nigerians living in the Dallas-Fort Worth area. A realistic appraisal of this group's perceived levels of marital satisfaction provided the basis for this pragmatic and academically useful study which is especially valuable to professionals involved in cross-cultural counseling.
Dallas Barrio Women of Power
This thesis discusses Mexican immigration into Texas, and the communities in which the immigrants settled. The focus is on Dallas, with particular emphasis placed upon the women of Little Mexico, a specific barrio there. Sources include interviews with the subjects and their descendants, newspaper articles, journals, unpublished theses about Little Mexico, and books.
Daniel's Battery: A Narrative History and Socio-Economic Study of the Ninth Texas Field Battery
This thesis combines a traditional narrative history of a Confederate artillery battery with a socio-economic study of its members. A database was constructed using the Compiled Service Records, 1860 census, and county tax rolls. The information revealed similarities between the unit's members and their home area. Captain James M. Daniel organized the battery in Paris, Texas and it entered Confederate service in January 1862. The battery served in Walker's Texas Division. It was part of a reserve force at the Battle of Milliken's Bend and was involved in the battles of Bayou Bourbeau, Mansfield, and Pleasant Hill. The battery also shelled Union ships on the Mississippi River. Daniel's Battery officially surrendered at Natchitoches, Louisiana, in May 1865.
Depressive Subtypes and Dysfunctional Attitudes: a Personal Construct View
The influence of cognitive organization, dysfunctional attitudes, and depressive "subtype" on the perceptions of negative life events is explored. BDI scores are used to delineate symptomatic and non-symptomatic groups. Construct content (sociotropic versus autonomous, as first defined by Beck) is used to identify predominant schema-type. Subjects completed a Problematic Situations Questionnaire with Dysfunctional Attitudes Scale. Results indicate that depressed individuals display more dysfunctional attitudes and negative affect in all types of negative situations; further the endorsement of dysfunctional attitudes is significantly more likely to occur in the context of schema-congruent situations. Findings are discussed a) in terms of the utility of personal constructs in the assessment of schema-type and b) in accordance with a person-event interactional model of depression.
Descriptions, Life History and Case-Building Behavior of Culoptila cantha (Trichoptera: Glossosomatidae) in the Brazos River, Texas
Larval, pupal and adult samples of Culoptila cantha, from a large riffle of the Brazos River in north-central Texas from January, 1995 to March, 1997, indicated a predominately trivoltine cycle during both years; the over-wintering generation spanned 6-7 months and warm-season generations spanned 2-3 months. Eggs, larvae of all instars, larval cases, case reconstruction progression and behavior, pupae, and adults are described.
A Descriptive Analysis of Causal Attribution in News Reports of the 1992 Los Angeles Riots in Three National Newspapers
A content analysis was conducted to determine the amount and type of causal explanation included in coverage of the 1992 Los Angeles riots in The New York Times, the Los Angeles Times and The Christian Science Monitor. The data were analyzed to determine whether causal explanations were primarily societal or individual/situational. The primary purpose was to examine whether the press has altered its reporting techniques since the Kerner Commission report criticized the narrow, descriptive-based reporting of the 1960s riots. Study results indicate riot coverage was predominantly descriptive and similar in content to that detailed by the Kerner Commission. The most frequently cited cause was the triggering event, the Rodney King acquittal verdict.
