Traumatic Brain Injury in Children and Adolescents: An Evaluation of the WISC-III Four Factor Model and Individual Cluster Profiles
Traumatic brain injury (TBI) is the leading cause of death and disability among children and adolescents in the US. Children and adolescents who sustain moderate and severe head injuries are much more likely to evidence significant deficits in neuropsychological functioning when compared with children with mild head injuries. Information about the recovery process and functional sequelae associated with moderate and severe head injuries remains limited, despite clear indications that children who experience such injuries typically exhibit notable deficits in intellectual functioning, particularly during the acute phase of recovery. Thus, the present study was conducted to augment research on intellectual functioning in children with moderate or severe head injuries. To accomplish this, the study first examined the proposed factor model of the WISC-III in children with moderate and severe TBI. Given high prevalence rates and similar trends in cognitive impairment, particularly within the frontal lobe structures (e.g., disrupted cognitive flexibility and divided attention), the study also examined this same factor model for a group of children with attention-deficit/hyperactivity disorder (ADHD) and compared it with the model fit from the TBI group. In the second phase of the study, both the TBI and AHDH groups were evaluated to determine if distinct WISC-III …

The Relationship Between Neuropsychological Performance and Daily Functioning in Individuals with Alzheimer's Disease
The results of neuropsychological tests are often used by clinicians to make important decisions regarding a demented patient's ability to competently and/or independently perform activities of daily living. However, the ecological validity of most neuropsychological instruments has yet to be adequately established. The current study examined the relationship between neuropsychological test performance and functional status in 42 individuals diagnosed with Alzheimer's Disease. A comprehensive battery of cognitive tests was employed in order to assess a wide range of neuropsychological abilities. Functional status was measured through the use of both a performance-based scale of activities of daily living (The Direct Assessment of Functional Status; Loewenstein et al., 1989) as well as by a caregiver/informant-based rating scale (Instrumental Activities of Daily Living; Lawton & Brody, 1969). Findings suggest that neuropsychological functioning is moderately predictive of functional status. Memory performance was the best predictor of functional status in most ADL domains, followed by executive functioning and visuospatial abilities.

Southern Promise and Necessity: Texas, Regional Identity, and the National Woman Suffrage Movement, 1868-1920
This study offers a concentrated view of how a national movement developed networks from the grassroots up and how regional identity can influence national campaign strategies by examining the roles Texas and Texans played in the woman suffrage movement in the United States. The interest that multiple generations of national woman suffrage leaders showed in Texas, from Reconstruction through the ratification of the Nineteenth Amendment, provides new insights into the reciprocal nature of national movements. Increasingly, from 1868 to 1920, a bilateral flow of resources existed between national women's rights leaders and woman suffrage activists in Texas. Additionally, this study nationalizes the woman suffrage movement earlier than previously thought. Cross-regional woman suffrage activity has been marginalized by the belief that campaigning in the South did not exist or had not connected with the national associations until the 1890s. This closer examination provides a different view. Early woman's rights leaders aimed at a nationwide movement from the beginning. This national goal included the South, and woman suffrage interest soon spread to the region. One of the major factors in this relationship was that the primarily northeastern-based national leadership desperately needed southern support to aid in their larger goals. Texas' ability to …

A Comparison of a Visual Disassociation Test on the Keystone Telebinocular with Other Tests of Dominance
This study compares results of sighting, control, suppression and wink tests of visual dominance with a dissociation test administered to 240 high-achieving (ninetieth percentile and above academically) and low-achieving (twenty-fifth percentile and below academically) students at grades four, eight, and twelve. The study examines differences between visual dissociation and other visual-dominance tests. In so doing, the study tests the proportion of consistent dominance revealed by each test among underachievers with a high incidence of dominance variations, examines possible influences on choice of dominant eye, and compares distributions of dominance functions in high- and low-achieving populations.

Life Stress and Incidence of Pediatric Sickle Cell Anemia Pain Crises
This study investigated the relationship between stress and pain crisis incidence in pediatric Sickle Cell Anemia (SCA). It was hypothesized that SCA children were exposed to higher levels of stress than healthy children. It was also hypothesized that a significant positive correlation existed between level of stress and pain crisis incidence both within and between years. The sample consisted of 20 Black elementary school children with SCA. There were 12 female and 8 male children. The period of investigation included the calendar years 1983 and 1984. Pain crisis incidence was determined through parent interviews and verified by a review of medical records.

The Balkan Imbroglio: The Diplomatic, Military, and Political Origins of the Macedonian Campaign of World War I
The Macedonian Campaign of World War I (October 1915-November 1918) traditionally remains one of the understudied theatres of the historiography of the conflict. Despite its vital importance in the outcome of the war, it is still considered as a mere sideshow compared to the Western Front and the Gallipoli Campaign. This dissertation presents a much-needed re-evaluation of the Macedonian Campaign's diplomatic and political origins within the war's early context. In doing so, this study first concentrates on a longue durée perspective and assesses the main historical events in the Balkans and Central Europe from the end of the French Revolution to World War I. In a perspective running throughout the entire nineteenth century, this dissertation integrates the importance of nascent nationalism in the Balkans and examine the Austro-Hungarian Empire's steady decline and subsequent diplomatic realignment toward the Balkans. Similarly, this work depicts the intense power struggle in Southeastern Europe between some of this story's main protagonists, namely the Austro-Hungarian, Russian and Ottoman Empires. This dissertation also evaluates the rise of new regional powers such as Bulgaria and Serbia and examines their connection to the European balance of power and general diplomatic equilibrium. In the first half of this dissertation, I …

Ordination and Cognitive Complexity as Related to Endogenous and Exogenous Depression
Personal construct psychology, as formulated by George Kelly (1955), contributed substantial knowledge to the study of psychopathology. The small amount of research in the area of depression has focused generally on the content of self-constructs and the cognitive complexity characteristic. The purpose of this study was to examine the construct system of the depressed patient specifically by investigating the endogenicity, exogenicity, and severity of depressive symptoms in relationship to construct content as applied to others, cognitive complexity, and ordination.

A General Diffusion of Knowledge: Republican Efforts to Build a Public School System in Reconstruction Texas
From the early days as a Spanish colony Texas attracted settlers with the promise of cheap fertile land. During the period of Mexican control the population of Texas increased and a desire for public education manifested among the people. Through the end of the Civil War government in Texas never provided an adequate means for educating the children of the region. Even when funds became available with the Compromise of 1850 the state only established a school fund to help offset the costs of education, but did not provide a public school system. The first truly successful attempt at mass education in Texas came after the Civil War with the work of the Freedmen’s Bureau. The bureau helped the former slaves adjust to the emerging post war society through a variety of means such as education. In spite of its short existence the bureau managed to educate thousands of African Americans. By 1870 the former slaves wanted more education for their children, and Texans of all races began to see the need for a public school system. This study focuses on Republican efforts during Reconstruction to establish a public school system in Texas to meet the educational needs of its …

Joaquín de Arredondo in Texas and Northeastern New Spain, 1811-1821
Joaquín de Arredondo was the most powerful and influential person in northeastern New Spain from 1811 to 1821. His rise to prominence began in 1811 when the Spanish military officer and a small royalist army suppressed Miguel Hidalgo’s revolution in the province of Nuevo Santander. This prompted the Spanish government to promote Arredondo to Commandant General of the Eastern Internal Provinces, making him the foremost civil and military authority in northeastern New Spain. Arredondo’s tenure as commandant general proved difficult, as he had to deal with insurgents, invaders from the United States, hostile Indians, pirates, and smugglers. Because warfare in Europe siphoned much needed military and financial support, and disagreements with New Spain’s leadership resulted in reductions of the commandant general’s authority, Arredondo confronted these threats with little assistance from the Spanish government. In spite of these obstacles, he maintained royalist control of New Spain from 1811 to 1821, and, in doing so, changed the course of Texas, Mexican, and United States history. In 1813, he defeated insurgents and American invaders at the Battle of Medina, and from 1817 to 1820, his forces stopped Xavier Mina’s attempt to bring independence to New Spain, prevented French exiles from establishing a colony …

The Development of a Psychobiologic Profile of Individuals Who Experience and Those Who Do Not Experience Exercise-Related Mood-Enhancement
The present investigation involved the development of a psychobiologic profile of individuals who experience exercise-related mood-enhancement and those who do not. The sample (N=301) consisted of students participating in 10-week exercise classes at North Texas State University. All subjects completed pre-test inventories assessing various psychological (i.e., trait anxiety and depression, attitude toward physical activity, self-estimation of physical ability and attraction to physical activity, expectancies of health benefits from exercise, and self-motivation) and biological (i.e., aerobic capacity and body fat percentage) variables. Trait anxiety and depression were also assessed before and after the 10-week exercise program and state anxiety and depression were assessed on an acute basis on two separate occasions during the program. Multivariate analysis of variance and discriminant function analysis were employed to determine which variables maximally discriminated between individuals who experienced mood-elevations following exercise and those who did not enjoy such rewards. The hypothesis that these two groups of individuals differ significantly from each other was not upheld by the results; thus, an overall psychobiologic profile could not be developed. However, the data did reveal that individuals who held a more positive attitude toward physical activity for the purpose of health and fitness reduced their state anxiety and …

Perception of Falls and Confidence in Self-Management of Falls among Older Adults
Mobility safety, especially fall prevention, plays a significant role in successful aging for older adults. Fall preventive programs aim to reduce risks for mortality from fall-related injuries among older adults. However, the covariation between personal perceptions of falls and factors and confidence of self-management in falls (CSMoF) is still under-studied despite its importance to fall prevention. Using the International Classification of Functioning, Disability, and Health (ICF) model, this dissertation aimed to investigate the relative contribution of CSMoF in relation to fall risk self-perceptions while controlling for demographics and self-reported health and functioning. Participants were 691 older adults recruited from Area Agency on Aging at Arlington, Texas. They completed measures of physical functioning, CSMoF, fall risk perceptions and fear of falls. Regression analyses indicated that fear of falls was the most predictive factor of CSMoF among older persons. Physical function measures of age, chronic illnesses of metabolism, sensory impairment, and health status were also significant predictors of the CSMoF. The interaction of perception of falls and fall experience attenuated CSMoF, with physical functioning limitations. Fear of falls served as a mediator through which demographic predictors influence CSMoF. The joint effects of perception of falls and fear of falls likely explain CSMoF …

Examining the Clinical Utility and Predictive Validity of Dimensional Models of Psychopathology
The Diagnostic and Statistical Manual of Mental Disorders arranges co-occurring clusters of symptoms into distinct disorder categories, which theoretically have specific etiologies, pathologies, and treatments. However, researchers and clinicians alike have consistently found DSM diagnoses to have high rates of comorbidity, low diagnostic specificity, and no disorder has proven to be a discrete category. There is mounting evidence that dimensional taxonomies more accurately capture the underlying structure of mental illness and clinical presentations. The recently proposed hierarchical taxonomy of psychopathology presumes to address the issues of categorical nosologies using a data driven approach to create a dimensional model of psychopathology. However, heretofore there are no empirical examinations of HiTOP's ability to predict psychotherapy treatment outcomes. This study compared the predictive validity DSM, RDoC, and HiTOP criteria using natural language processing on free text narrative notes. Of the three GMM run, only the model using DSM criteria as predictors had adequate model fit. Additionally, none of the nosologies significantly predicted treatment course. Implications for the application of RDoC and HiTOP are discussed.

A Performer's Guide to Béla Bartók's Violin Concerto No 1, Opus Posthumous, 1907–1908
Despite Bartók's lasting international fame, some of his works remain unjustly lesser-known. One of the pieces that still resides in relative obscurity is his Violin Concerto No.1—a gem of the violin repertoire that must be brought to the broader public's attention. The fact that the concerto was hidden definitely contributed to its little–known status at first. However, the most important cause for the lack of enthusiasm to tackle this terrific work lies in the unorthodox demands it puts on the violinist. The purpose of this paper is to provide musical and technical suggestions based on Bartók's performing style and on his requirements for performer, which will help to create a more persuasive interpretation of the piece. The guide covers the questions of character, articulation, dynamics, and other performance aspects, and also provides practical suggestions, such as fingerings and bowings. It is hoped that this study will help violin performers to gain additional knowledge and insight into this composition and encourage more frequent performances of it.

Post-Traumatic Changes in Perceptions of Purpose in Life and Three Dimensions of Locus of Control in Stroke and Hip Surgery Patients
A survey of stress and crisis literature indicated traumatic events tend to initially overwhelm individual coping resources. The adjustment process following such events appears to be characterized by phases in which gradual perceptual and cognitive reorganization occurs. Emotional shock, denial processes, and intrusive ideation accompany initial phases.

Profile of the Youth Self-Report Among South Texas Adolescents and the Potential Relationship to Pesticide Exposure
The potential for human exposure to pesticides exists particularly for agricultural workers (i.e. migrant workers) and individuals within close proximity to pesticide-sprayed crops (i.e. those living on or near agricultural farms). Children, through biology and behavior, may be more susceptible and vulnerable to exposure to pesticides than adults. The purpose of this study was to examine young populations particularly at-risk for occupational or accidental exposure to pesticides and determine associated behavioral, emotional, and physical symptoms. A total of 444 students from two South Texas school districts completed questionnaires assessing level of risk of exposure to pesticides and were categorized into at-risk and low risk categories. Physical, emotional, and behavioral symptoms were obtained using the Youth Self-Report. Children who were at-risk demonstrated significantly higher scores on the Youth Self-Report (YSR) in the areas of anxious/depressed, attention problems, social problems, somatic complaints, thought problems, withdrawal, internalizing behaviors, and total problem behaviors than children who were at lower risk of pesticide exposure. Odds ratios were obtained and suggested that children in the at-risk category were more five times more likely to score in the clinically significant range on the Attention Problems subscale, and three times more likely to score in the clinically significant …

III Corps during the Surge Campaign: Operational Art and Counterinsurgency Myths
The role of Odierno's III Corps as MNC-I has failed to receive sufficient attention from studies of the 2007-2008 surge of U.S. forces in Iraq. However, was Odierno's employment of military force in time, space, and purpose based on the logic of conventional military operations that laid the groundwork for the successes gained in 2007 and 2008. III Corps's achievements as an operational headquarters were rooted in the successful application of operational art. Operational art is a way to conceptualize how to fight wars using campaigns of multiple, simultaneous, and successive operations across a theater of operations to achieve a unifying goal. While neither downplaying nor minimizing the importance of Army COIN principles, a study of MNC-I's December 2006-February 2008 campaign in Iraq through the neglected prism of operational art suggests that the campaign's success was due to the successful application of already established operational principles rather than from a revolution in the profession of arms.

Defense Industries in North Texas, 1941-1965: the Social and Economic Impact on Bowie County
World War II was a watershed in American history, altering Americans' perceptions of their place in society. This study focused on Bowie County, Texas, during the twenty-five-year period that began with America's entry into the war. The construction of two defense plants there, Red River Army Depot and Lone Star Army Ammunition Plant, brought immediate changes to surrounding communities, and local residents faced many challenges as they struggled to adjust. This study used extensive primary sources, including archival materials from Red River and Lone Star, oral histories from former employees, census information, minutes from the Texarkana Chamber of Commerce, and local newspapers, to document the social and economic impact of these plants on Bowie County. The body of this dissertation contains nine chapters. Chapters two and three describe how Bowie County obtained and constructed its defense plants, and chapters four through six focus on changes precipitated by the plants during the war years. Chapters seven through nine explore the social and economic impact of the defense presence on Bowie County through 1965. The impact of the defense industries on Bowie County was significant. Plant construction brought thousands of workers into the county, and local residents faced housing, transportation, and sanitation …

Professor Carl A. Helmecke and Nazism: A Case Study of German-American Assimilation
Carl A. Helmecke, like many German Americans marginalized by the anti-Germanism of the First World War and interwar period, believed that democracy had failed him. A professor with a doctoral degree in social philosophy, he regularly wrote newsletter columns declaring that the emphasis on individualism in the United States had allowed antidemocratic forces to corrupt the government, oppress citizens, and politicize schools and institutions for propaganda purposes. Moreover, widespread hunger and unemployment during the Great Depression added to the long list of failures attributable to democracy. What the United States needed, Helmecke thought, was political change, and he believed that the Nazi regime in his homeland, albeit flawed, had much to offer. In 1937, he went on a teaching sabbatical to Nazi Germany to study the Third Reich's education and social programs. When he returned to the United States, he began promoting Nazi ideals about education and labor camps. Although Hitler's 1939 invasion of Poland, followed by the United States entry into World War II, brought his fascist illusions for political change in the United States to an abrupt end, his belief in the correctness of an autocratic system of governance for Germany rather than that of the western democracies …
