Factor Structure of the Neurocognitive Battery in a Geriatric Sample with Cognitive Impairments

The present study was designed to empirically validate six theoretically derived cognitive domains (verbal memory, visual memory, working memory, attention-concentration, executive functions, and visuospatial abilities) assessed by a comprehensive battery of neuropsychological tests used in the Geriatric Memory Clinic at the University of North Texas Health Science Center in Fort Worth, Texas. The study examined the extent to which various cognitive dimensions are tapped by this battery in a heterogeneous geriatric sample of 114 patients with cognitive impairments. The proposed six-factor model of cognitive functioning has not been supported. Further exploratory factor analysis arrived at a five-factor solution. Factor pattern of the 23 tests supported the following five dimensions: memory, executive control, attention, visuospatial abilities, and cognitive flexibility.

Finding the "Indian" in Amy Beach's Theme and Variations for Flute and String Quartet, op. 80. (open access)

Finding the "Indian" in Amy Beach's Theme and Variations for Flute and String Quartet, op. 80.

Music that is categorized as part of the Indianist movement in American music (ca. 1890-1925) typically evokes Native American culture, ritual, story, or song through compositional gestures. It may also incorporate Native American tunes. Amy Beach (1867-1944) is considered to have composed five Indianist works, but her Theme and Variations for Flute and String Quartet, op. 80 has not been included as one of them. This thesis rethinks categorization of the piece, seeking the "Indian" in it through examination of its gestures, instrumentation, and relationship to contemporary Indianist compositions.

Battle for the Punchbowl: The U. S. 1st Marine Division 1951 Fall Offensive of the Korean War (open access)

Battle for the Punchbowl: The U. S. 1st Marine Division 1951 Fall Offensive of the Korean War

This study is an operational and tactical study of a battle fought by the U. S. 1st Marine Division near "the Punchbowl," an extinct volcano of military value in the Taebaek Mountains of Korea, from late August through mid September 1951. That engagement was to be the last 1st Marine Division offensive of the Korean War. This battle, for Yoke and Kanmubong Ridges, has received little coverage from historians. That it is all but forgotten is surprising, since it was one of the hardest fought for United States Marines in the war. The casualties were high, and Americans did not understand why so many had to die for a war that seemed to already be set to conclude by negotiations. This study tells the story of that battle more completely than ever before, and assesses its significance to the course of the Korean War.

The Rise of a Two-Party State: A Case Study of Houston and Harris County, Texas, 1952-1962 (open access)

The Rise of a Two-Party State: A Case Study of Houston and Harris County, Texas, 1952-1962

This thesis discusses the rise of the Republican party in Texas and specifically Harris County. The time period is the decade between the Presidential election of Dwight D. Eisenhower and the campaign of Jack Cox for Governor. Changes in the structure and leadership of the Republican party at the state level and specific precincts are examined in detail in chapter one. Leaders in Houston during this time period, such as Jesse Jones, Roy Cullen, and Oveta Culp Hobby are discussed in chapter two. The elections of Eisenhower, Cox, and Republican John Tower are analyzed in chapter three. The conclusion finds six major factors for the political changes occurring in Harris County, including economic and demographic changes. Main sources for this work included the Harris County Democratic party records and the Jack Cox Papers at the Center for American History, the Eisenhower Library, and the John Tower Papers.

Dem Schwerte Muss Der Pflug Folgen: Űber-Peasants and National Socialist Settlements in the Occupied Eastern Territories during World War Two

German industrialization in the nineteenth century had brought forward a variety of conflicting ideas when it came to the agrarian community. One of them was the agrarian romantic movement led by Adam Műller, who feared the loss of the traditional German peasant. Műller influenced Reichdeutsche Richard Walther Darré, who argued that large cities were the downfall of the German people and that only a healthy peasant stock would be able to ‘save' Germany. Under Darré's definition, “Geopolitik” was the defense of the land, the defense with Pflug und Schwert (plow and sword) by Wehrbauern, an ‘Űberbauer-fusion' of soldier and peasant. In order to accomplish these goals, new settlements had to be established while moving from west to east. The specific focus of this study is on the original Hegewald resettlement ideas of Richard Walther Darré and how his philosophy was taken over by Himmler and fit into his personal needs and creed after 1941. It will shed some light on the interaction of Darré and Himmler and the notorious internal fights and power struggles between the various governmental agencies involved. The Ministry for Food and Agriculture under the leadership of Darré was systematically pushed into the background and all previous, …

East is East and West is West: Philadelphia Newspaper Coverage of the East-West Divide in Early America (open access)

East is East and West is West: Philadelphia Newspaper Coverage of the East-West Divide in Early America

The prominent division in early America between the established eastern populations and communities in the West is evident when viewed through the lens of eighteenth-century Philadelphia newspapers, which themselves employed an East-West paradigm to interpret four events: the Paxton Boys Incident, Regulator Rebellion, Shays's Rebellion, and Constitutional Convention. Through the choices of what words to use to describe these clashes, through oversights, omissions, and misrepresentations, and sometimes through more direct tactics, Philadelphia newspapermen revealed a persistent cultural bias against and rivalry with western communities. This study illustrates how pervasive this contrast between East and West was in the minds of easterners; how central a feature of early American culture they considered it to be.

The Impact of Ownership, Regulation Issues and Technology Adoption on the Introduction of Digital Terrestrial Television: A Comparison of the United States and Mainland China (open access)

The Impact of Ownership, Regulation Issues and Technology Adoption on the Introduction of Digital Terrestrial Television: A Comparison of the United States and Mainland China

This study compares the impact of media ownership, regulation and policy, and technology adoption on the introduction of digital terrestrial television in the United States and Mainland China. Through the use of a case study approach, a qualitative and quantitative examination is given. The results indicate that private group ownership throughout the U.S. digital terrestrial television industry and state ownership in China's television industry lead to the different paths to digital transition. Both governments, however, are deeply involved in respective digital initiatives and play an important role in the implementation from analog to digital. The technical standard adoption in the two countries places the underpinning for the future development of digital television (DTV), which also results in China lagging behind the United States by almost ten years. The differences of technological environments in households and income among consumers in the two countries further predict the intention to DTV adoption.

Skylab: The Human Side of a Scientific Mission

This work attempts to focus on the human side of Skylab, America's first space station, from 1973 to 1974. The thesis begins by showing some context for Skylab, especially in light of the Cold War and the “space race” between the United States and the Soviet Union. The development of the station, as well as the astronaut selection process, are traced from the beginnings of NASA. The focus then shifts to changes in NASA from the Apollo missions to Skylab, as well as training, before highlighting the three missions to the station. The work then attempts to show the significance of Skylab by focusing on the myriad of lessons that can be learned from it and applied to future programs.

Manuel M. Ponce: A critical study of his Concierto Romántico for piano and orchestra. (open access)

Manuel M. Ponce: A critical study of his Concierto Romántico for piano and orchestra.

The Concierto Romántico for Piano and Orchestra is one of Manuel M. Ponce's outstanding compositional accomplishments from his Romantic period, reflecting both the state of Mexican music at the turn of the 20th century, and his early nationalist tendencies. However, it remains the only concerto in Ponce's output in need of a more comprehensive analysis. This treatise focuses on a global investigative that examines descriptive and analytic references to the work, as well as a comparison and clarification of the existing score sources. An analytical and stylistic musical study using conventional theoretical techniques leads to a musicological interpretation of the work's extra-musical meaning, based on close assessments of Ponce's compositional practice and social principles.

The Blessed and the Damned: Peacemakers, Warlords, and Post Civil War Democracy (open access)

The Blessed and the Damned: Peacemakers, Warlords, and Post Civil War Democracy

This thesis seeks to explain how democracies emerge out of the ashes of civil wars. This paper envisions transitions to democracy after a civil war largely as a function of the peace process. Democracy is thought of as a medium through which solutions to the problems and issues over which the civil war was fought can be solved without violence. Transitions to democracy are more likely if there is a large bargaining space and the problems of credible commitments to democratization can be solved. Democratization is more likely if four conditions exist in a state after the civil war: a negotiated settlement, credible commitments via international enforcement, demobilization, and a cooperative international environment. The hypotheses derived are tested through an event history analysis for two different standards of democracy. The results suggest that factors indicative of all four theoretical concepts contribute to the likelihood of democratization after a civil war.

Gladstone and the Bank of England: A Study in Mid-Victorian Finance, 1833-1866 (open access)

Gladstone and the Bank of England: A Study in Mid-Victorian Finance, 1833-1866

The topic of this thesis is the confrontations between William Gladstone and the Bank of England. These confrontations have remained a mystery to authors who noted them, but have generally been ignored by others. This thesis demonstrates that Gladstone's measures taken against the Bank were reasonable, intelligent, and important for the development of nineteenth-century British government finance. To accomplish this task, this thesis refutes the opinions of three twentieth-century authors who have claimed that many of Gladstone's measures, as well as his reading, were irrational, ridiculous, and impolitic. My primary sources include the Gladstone Diaries, with special attention to a little-used source, Volume 14, the indexes to the Diaries. The day-to-day Diaries and the indexes show how much Gladstone read about financial matters, and suggest that his actions were based to a large extent upon his reading. In addition, I have used Hansard's Parliamentary Debates and nineteenth-century periodicals and books on banking and finance to understand the political and economic debates of the time.

The role of attention-deficit/hyperactivity disorder and parental misperceptions in risk for child physical abuse (open access)

The role of attention-deficit/hyperactivity disorder and parental misperceptions in risk for child physical abuse

Voice over IP (VoIP) is a key enabling technology for the migration of circuit-switched PSTN architectures to packet-based IP networks. However, this migration is successful only if the present problems in IP networks are addressed before deploying VoIP infrastructure on a large scale. One of the important issues that the present VoIP networks face is the problem of unwanted calls commonly referred to as SPIT (spam over Internet telephony). Mostly, these SPIT calls are from unknown callers who broadcast unwanted calls. There may be unwanted calls from legitimate and known people too. In this case, the unwantedness depends on social proximity of the communicating parties. For detecting these unwanted calls, I propose a framework that analyzes incoming calls for unwanted behavior. The framework includes a VoIP spam detector (VSD) that analyzes incoming VoIP calls for spam behavior using trust and reputation techniques. The framework also includes a nuisance detector (ND) that proactively infers the nuisance (or reluctance of the end user) to receive incoming calls. This inference is based on past mutual behavior between the calling and the called party (i.e., caller and callee), the callee's presence (mood or state of mind) and tolerance in receiving voice calls from the …

Analyzing Microwave Spectra Collected by the Solar Radio Burst Locator (open access)

Analyzing Microwave Spectra Collected by the Solar Radio Burst Locator

Modern communication systems rely heavily upon microwave, radio, and other electromagnetic frequency bands as a means of providing wireless communication links. Although convenient, wireless communication is susceptible to electromagnetic interference. Solar activity causes both direct interference through electromagnetic radiation as well as indirect interference caused by charged particles interacting with Earth's magnetic field. The Solar Radio Burst Locator (SRBL) is a United States Air Force radio telescope designed to detect and locate solar microwave bursts as they occur on the Sun. By analyzing these events, the Air Force hopes to gain a better understanding of the root causes of solar interference and improve interference forecasts. This thesis presents methods of searching and analyzing events found in the previously unstudied SRBL data archive. A new web-based application aids in the searching and visualization of the data. Comparative analysis is performed amongst data collected by SRBL and several other instruments. This thesis also analyzes events across the time, intensity, and frequency domains. These analysis methods can be used to aid in the detection and understanding of solar events so as to provide improved forecasts of solar-induced electromagnetic interference.

Socioeconomic variables associated with the reports of controlling behaviors in current relationships among abused and non-abused females. (open access)

Socioeconomic variables associated with the reports of controlling behaviors in current relationships among abused and non-abused females.

This study examined the relationship between reports of controlling behaviors and education/income in a sample of 297 abused women and 2951 non-abused women in married or cohabitating relationships. This study confirmed that women who reported abuse were more likely to report all five of the controlling behaviors than women who did not report abuse. However, the abuse and non-abuse samples did show similar relationships between the controlling/isolating behaviors and the SES variables. This study found that the higher the respondent's or their partner's education and income, the less likely they were to report controlling/isolating behaviors. Also, the respondent's education and income had the same number of statistically significant relationships with the controlling behaviors as the partner's education and income.

An environmental justice assessment of the light rail expansion in Denton County, Texas. (open access)

An environmental justice assessment of the light rail expansion in Denton County, Texas.

This study analyzes the proposed passenger rail line expansion along US Interstate Highway 35 in Denton County, Texas. A multi-dimensional approach was used to investigate potential environmental justice (EJ) consequences from the expansion of the transportation corridor. This study used empirical and historical evidence to identify and prioritize sites for potential EJ concerns. Citizen participation in the decision making process was also evaluated. The findings of this research suggest that the southeast Denton community has the highest potential for environmental justice concerns. This study concludes by offering suggestions for an effective public participation process. These include the incorporation of a community's local history into an environmental justice assessment, and tailoring the public planning process to the demographics and culture of the residents.

Optimization of Cell Culture Procedures for Growing Neural Networks on Microelectrode Arrays

This thesis describes the development of an optimized method for culturing dissociated, monolayer neuronal networks from murine frontal cortex and midbrain. It is presented as a guidebook for use by cell culture specialists and laboratory personnel who require updated and complete procedures for use with microelectrode array (MEA) recording technology. Specific cell culture protocols, contamination prevention and control, as well common problems encountered within the cell culture facility, are discussed. This volume offers value and utility to the rapidly expanding fields of MEA recording and neuronal cell culture. Due to increasing interest in determining the mechanisms underlying Parkinson's disease, the newly developed procedures for mesencephalon isolation and culture on MEAs are an important research contribution.

Programming homeland security: Citizen preparedness and the threat of terrorism.

This thesis tests the necessity of terrorism in articulating Homeland Security citizenship. Chapter 1 orients the study, reviewing relevant literature. Chapter 2 examines the USDHS Ready Kids program's Homeland Security Guide, mapping a baseline for how Homeland Security citizenship is articulated with the overt use of terrorism. Chapter 3 investigates the USDHS Ready Kids program, charting the logic of Homeland Security citizenship when the threat of terrorism is removed from sense making about preparedness. Chapter 4 compares the findings of Chapters 2 and 3, evaluating the similarities and differences between these two articulations of Homeland Security citizenship and concluding that the logic that cements Homeland Security into American society does not depend on the threat of terrorism against the United States.

Psychological Abuse and Health: What Role Does Forgiveness Play? (open access)

Psychological Abuse and Health: What Role Does Forgiveness Play?

Existent literature suggests forgiveness could lead to either greater psychological abuse (reinforcement theory), or lower psychological abuse (interpersonal theory). Questionnaires were completed by 291 participants who were dating at least 2 months. More forgiveness-particularly Absence of Negativity-was related to less abuse received from their partner, and this effect was stronger for females than for males. Absence of Negativity (AN) was predictive of health variables (psychosomatic symptoms, mental and physical health), although Presence of Positive forgiveness did not predict health beyond the impact of AN. Abuse-forgiveness and assertiveness-forgiveness interaction terms were not significant predictors of health. Results indicate interpersonal theory describes the link between forgiveness and psychological abuse. Results suggest that focus on AN could be sufficient for mental or physical health change
