A Grounded Theory of Information Quality in Web Archives
Web archiving is the practice of preserving websites as a historical record. It is a technologically-challenging endeavor that has as its goal the creation of a high-quality archived website that looks and behaves exactly like the original website. Despite the importance of the notion of quality, comprehensive definitions of Information Quality (IQ) in a web archive have yet to be developed. Currently, the field has no single, comprehensive theory that describes what is a high-quality or low-quality archived website. Furthermore, most of the research that has been conducted on web archives has been system-centered and not user-centered, leading to a dearth of information on how humans perceive web archives. This dissertation seeks to remedy this problem by presenting a user-centered grounded theory of IQ for web archives. It answers two research questions: 1) What is the definition of information quality (IQ) for web archives? and 2) How can IQ in a web archive be measured? The theory presented is grounded on data obtained from users of the Internet Archive's Archive-It system, the largest web-archiving subscription service in the United States. Also presented are mathematical definitions for each dimension of IQ, which can then be applied to measure the quality of …

Showing the Flag: War Cruiser Karlsruhe and Germandom Abroad
In the early 1920s the Weimar Republic commissioned a series of new light cruisers of the Königsberg class and in July 1926, the keel of the later christened Karlsruhe was laid down. The 570 feet long and almost 50 feet wide ship was used as a training cruiser for future German naval officers. Between 1930 and 1936 the ship conducted in all five good-will tours around the world, two under the Weimar Republic and three under the Third Reich. These good-will tours or gute Willen Fahrten were an important first step in reconciling Germany to the rest of the world and were meant to improve international relations. The Foreign Office and the Ministry of Defense carefully orchestrated all stops of the vessels in conjunction with the respective embassies abroad. Final arrangements were made at least six-nine months before the scheduled visits and even small adjustments to the itinerary proved troublesome. Further, all visits were treated as “unofficial presentations.” The mission of the Karlsruhe was twofold: first to extend or renew relations with other nations, and second to foster notions of Heimat and the Germandom (Deutschtum) abroad. The dissertation is divided in two large parts; the individual training cruises with all …

The Historical and Pedagogical Significance of Excerpts by André-Ernest-Modeste Grétry (1741-1813)
This collection of 9 vocal works, taken from the oœuvre of André-Ernest-Modeste Grétry (1741-1813), was chosen for their utility in teaching undergrad voice majors. This collection offers a group of songs that are attractive in their simplicity allowing the time in their lessons to be devoted to the instruction of French pronunciation. Grétry's attention to detail in the setting of French prosody provides undergraduate singers with a collection of songs that offer an immediate understanding as to the nuances of the French language. With funding from an I-GRO grant through the University of North Texas, research was conducted in the archives of the Bibliothèque nationale de France, and work continued in the Grétry Museum in Liège, Belgium. The primary sources found within these locations formulated valuable insights into to the life and influence of Grétry, and provided first-hand experience with research techniques within foreign libraries. This research has solidified the relationship between Grétry's compositional style and its usefulness within the undergraduate voice studio.

Singing in English in the 21St Century: a StudyComparing and Applying the Tenets of Madeleine Marshall and Kathryn Labouff
The English diction texts by Madeleine Marshall and Kathryn LaBouff are two ofthe most acclaimed manuals on singing in this language. Differences in style between the two have separated proponents to be primarily devoted to one or the other. An in-depth study, comparing the precepts of both authors, and applying their principles, has resulted in an understanding of their common ground, as well as the need for the more comprehensive information, included by LaBouff, on singing in the dialect of American Standard, and changes in current Received Pronunciation, for British works, and Mid-Atlantic dialect, for English language works not specifically North American or British. Chapter 1 introduces Marshall and The Singer’s Manual of English Diction, and LaBouff and Singing and Communicating in English. An overview of selected works from Opera America’s resources exemplifies the need for three dialects in standardized English training. Chapter 2 reviews notational and diction resources, and use of the International Phonetic Association’s alphabet (IPA). Chapter 3 directly compares Marshall and LaBouff’s views of the importance of the unstressed syllable, often schwa [ә] or open I [ɪ], as vital to allowing the audience to understand the flow of the sung text, and contrasts their differences regarding < …

Information Use Environment of Religious Professionals: a Case Study of the Everyday Life Information Seeking Behavior of Catholic Clergy in Northern Nigeria
This study explores the everyday life information seeking (ELIS) behavior of Catholic clergy in Northern Nigeria and describes their information use environment (IUE). It employed a mixed-method case study using survey and episodic interview techniques of data collection. The ELIS of Savolainen, the IUE of Taylor and the small world of Chatman were theoretical frameworks that guided this study. Findings showed that the IUE of these Catholic clergy is shaped by four elements: (1) geographical location and culture, (2) the celibate clergy, (3) their information needs, and (4) the information sources used to resolve these needs. Three types of information needs were identified: essential needs, circumstantial needs and intermittent needs. There was a high interrelatedness between the effects of culture and celibacy on the information seeking of these clergy. They are not likely to cross boundaries of their world to seek particularly essential information about their ministry or private lives. The findings of this study align with Chatman’s proposition that members who live in the round will not cross the boundaries of their world to seek information. The study found problems with access and availability of information, which included lack of familiarity with electronic/online library databases among the clergy, and …

How Does It Feel to be Creative? A Phenomenological Investigation of the Creative Experience in Kinetic Places
How does it feel to be creative? Such a question, when approached from a phenomenological perspective, reveals new understandings about the embodied experience of creativity, and how it feels as it is being lived. This investigation begins with a provocative contrast of two environments where creativity is thought to manifest itself: school art classrooms, where creativity is often legislated from an authority figure, and New Orleans Second Line parades, where creativity is organically and kinetically expressed. A thorough review of the literature on creativity focuses on education, arts education, creative economies, psychology, and critical theorists, collectively revealing a cognitive bias and striking lack of consideration for community, freedom, and the lived experience of being creative. Further discussions in the literature also neglect sites of creativity, and the impact that place (such as a school classroom) can have upon creativity. The phenomenological perspectives of Merleau-Ponty, Heidegger, Bachelard, and Trigg support a methodological lens to grasp embodied knowledge, perceptions of placedness on creativity, and the interdependent frictions between freedom, authenticity, movement and belonging. The research method includes investigations in New Orleans in archives, examination of visual and material culture, participation in cultural practice, and formal and informal interviews. Further, the phenomena of …

Overview and Introduction to the Organ Music of Alsatian-american Composer René Louis Becker (1882-1956)
This dissertation provides the first biographical overview and annotated catalog of the organ music of Alsatian-American organist and composer René Louis Becker. Born and educated in Strasbourg, Alsace, Becker emigrated to the United States in 1904 and remained active as a composer and church musician for the next 50 years. in addition to providing sources for his biographical information, documentation of the specific organs with which Becker was professionally associated is included for the purpose of evaluating possible dates of composition of his undated organ works as well as for consideration of organ registrations when performing his works. Primary sources include newspaper clippings, personal correspondence, family scrapbooks, organ archives, and both published and unpublished manuscripts. Study of these manuscripts, including rediscovery of more than fifty works of Becker’s which were previously published in the early 1900s, present an opportunity to introduce a large new body of sophisticated repertoire from a distinguished and accomplished musician to the field of organ music. Becker composed more than 180 individual works for the organ, over half of which remain in manuscript and which were completely unknown since even before his death in 1956. Becker’s complete known oeuvre for organ includes 34 marches, 15 toccatas, …

Let the Dogs Bark: The Psychological War in Vietnam, 1960-1968
Between 1960 and 1968 the United States conducted intensive psychological operations (PSYOP) in Vietnam. To date, no comprehensive study of the psychological war there has been conducted. This dissertation fills that void, describing the development of American PSYOP forces and their employment in Vietnam. By looking at the complex interplay of American, North Vietnamese, National Liberation Front (NLF) and South Vietnamese propaganda programs, a deeper understanding of these activities and the larger war emerges. The time period covered is important because it comprises the initial introduction of American PSYOP advisory forces and the transition to active participation in the war. It also allows enough time to determine the long-term effects of both the North Vietnamese/NLF and American/South Vietnamese programs. Ending with the 1968 Tet Offensive is fitting because it marks both a major change in the war and the establishment of the 4th Psychological Operations Group to manage the American PSYOP effort. This dissertation challenges the argument that the Northern/Viet Cong program was much more effective that the opposing one. Contrary to common perceptions, the North Vietnamese propaganda increasingly fell on deaf ears in the south by 1968. This study also provides support for understanding the Tet Offensive as a …

Conversational Use of Photographic Images on Facebook: Modeling Visual Thinking on Social Media
Modeling the "thick description" of photographs began at the intersection of personal and institutional descriptions. Comparing institutional descriptions of particular photos that were also used in personal online conversations was the initial phase. Analyzing conversations that started with a photographic image from the collection of the Library of Congress (LC) or the collection of the Manchester Historic Association (MHA) provided insights into how cultural heritage institutions could enrich the description of photographs by using informal descriptions such as those applied by Facebook users. Taking photos of family members, friends, places, and interesting objects is something people do often in their daily lives. Some photographic images are stored, and some are shared with others in gatherings, occasions, and holidays. Face-to-face conversations about remembering some of the details of photographs and the event they record are themselves rarely recorded. Digital cameras make it easy to share personal photos in Web conversations and to duplicate old photos and share them on the Internet. The World Wide Web even makes it simple to insert images from cultural heritage institutions in order to enhance conversations. Images have been used as tokens within conversations along with the sharing of information and background knowledge about them. The …

Mary Jones: Last First Lady of the Republic of Texas
Abstract This dissertation uses archival and interpretive methods to examine the life and contributions of Mary Smith McCrory Jones in Texas. Specifically, this project investigates the ways in which Mary Jones emerged into the public sphere, utilized myth and memory, and managed her life as a widow. Each of these larger areas is examined in relation to historiographicaly accepted patterns and in the larger context of women in Texas, the South, and the nation during this period. Mary Jones, 1819-1907, experienced many of the key early periods in Anglo Texas history. The research traces her family’s immigration to Austin’s Colony and their early years under Mexican sovereignty. The Texas Revolution resulted in her move to Houston and her first brief marriage. Following the death of her husband she met and married Anson Jones, a physician who served in public posts throughout the period of the Texas Republic. Over time Anson was politically and personally rejected to the point that he committed suicide. This dissertation studies the effects this death had upon Mary’s personal goals, her use of a widow’s status to achieve her objectives, and her eventual emergence as a “Professional Widow.” Mary Jones’s attempts to rehabilitate her husband’s public …

Helen Kotas (1916-200): A Female Pioneer in Major US Orchestras
Helen Kotas was an accomplished musician and teacher who helped open the door for women in major US orchestras. In 1941 the Chicago Symphony hired its first female brass musician, principal hornist Helen Kotas. With that daring move, she became a pioneer for her gender in the major orchestras of North America. Despite her many contributions to the musical community, Kotas's life has not been researched and documented. This paper looks at Helen Kotas's career as well as a glimpse at her life and personality. In addition to documenting her life, this dissertation attempts to show at least a portion of Kotas's philosophy of teaching and horn playing. She was an accomplished horn soloist and studied the literature extensively. Kotas performed in the Chicago Civic Orchestra, the Woman's Symphony Orchestra, and Leopold Stokowski's All-American Youth Orchestra. Kotas was hired by Fritz Reiner as third horn of the Pittsburgh Symphony. When Frederick Stock, conductor of the Chicago Symphony Orchestra, heard that Helen Kotas was going to Pittsburgh, he insisted that she audition for the CSO. Kotas auditioned on the Concerto for Horn by Richard Strauss and the concertmaster said, "Hire her!" She performed as principal horn with the orchestra until Artur …

Forgotten Glory - Us Corps Cavalry in the ETO
The American military experience in the European Theater of Operations during the Second World War is one of the most heavily documented topics in modern historiography. However, within this plethora of scholarship, very little has been written on the contributions of the American corps cavalry to the operational success of the Allied forces. The 13 mechanized cavalry groups deployed by the U.S. Army served in a variety of roles, conducting screens, counter-reconnaissance, as well as a number of other associated security missions for their parent corps and armies. Although unheralded, these groups made substantial and war-altering impacts for the U.S. Army.

Investigation on Segmentation, Recognition and 3D Reconstruction of Objects Based on LiDAR Data Or MRI
Segmentation, recognition and 3D reconstruction of objects have been cutting-edge research topics, which have many applications ranging from environmental and medical to geographical applications as well as intelligent transportation. In this dissertation, I focus on the study of segmentation, recognition and 3D reconstruction of objects using LiDAR data/MRI. Three main works are that (I). Feature extraction algorithm based on sparse LiDAR data. A novel method has been proposed for feature extraction from sparse LiDAR data. The algorithm and the related principles have been described. Also, I have tested and discussed the choices and roles of parameters. By using correlation of neighboring points directly, statistic distribution of normal vectors at each point has been effectively used to determine the category of the selected point. (II). Segmentation and 3D reconstruction of objects based on LiDAR/MRI. The proposed method includes that the 3D LiDAR data are layered, that different categories are segmented, and that 3D canopy surfaces of individual tree crowns and clusters of trees are reconstructed from LiDAR point data based on a region active contour model. The proposed method allows for delineations of 3D forest canopy naturally from the contours of raw LiDAR point clouds. The proposed model is suitable not …

Reclaiming Female Virtue: Social Hygiene, Venereal Disease and Texas Reclamation Centers during World War I
During the Progressive Era in the United States, social hygiene reformers underwent a fundamental change in their stance toward women accused of prostitution or promiscuous behavior. Rather than viewing such women as unfortunate victims of circumstance who were worthy of compassion, many Progressives deemed them as predatory villains who instead deserved incarceration, forced rehabilitation, and non-consenting medical interference. Texas, due to the many military bases within its borders, became a key battleground in this moral crusade against women as the carriers and proliferators of VD. "Promiscuous" women were seen as not only dangerous to the soldiers but also as a threat to the nation's security, creating an environment that led Texas Progressives to suppress women's civil liberties in the name of protecting soldiers. The catalyst for this change in attitude was World War I. The Great War brought to the forefront an unpleasant reality facing a significant percentage of America's fighting men: venereal disease. While combating sexually transmitted diseases was a serious medical and manpower concern for the military in the era before penicillin, the sole focus on women as the carriers and proliferators of VD led to a nationwide campaign against the "social evil" that demonized women and led …

Rediscovering James Robert Gillette's Vistas
James Robert Gillette (1886-1963) was an early advocate for original wind band music at a time when marches and band transcriptions of orchestral music contributed heavily to the wind band repertoire. Primarily known as an influential, in-demand organist and composer, Gillette became the director of the Carleton College band program in Northfield, Minnesota in 1924. Taking an innovative approach to building, organizing, and programming, Gillette transformed that group into the Carleton Symphony Band and led a wider push for the symphonic band movement. In promoting his ideals of the symphonic band, he composed and arranged music specifically for the Carleton Symphony Band. One of his original works, Vistas, was widely performed and well-received in the decade just prior to and after its publication in 1934. Despite the popularity of the piece at that time, it has since gone out of print and is a rarely performed piece from Gillette's repertoire. This dissertation focuses on Vistas, Gillette's second published tone poem. This study starts with the examination of the history of Vistas from its origins as a movement in Gillette's transcription of Paul Robert Fauchet's Symphony in B-flat to its subsequent transformation and publication as an original work for band. Next, …

The Changing Role and Responsibilities of Audit Committees in the United States
The corporate form that developed in the early 20th century created enormous pressure for corporate governance mechanisms to curb the power of corporate managers. Berle and Means, legal pluralists, warned about concentrating economic power in the hands of a small but powerful class of professional managers. They claimed this "new form of absolutism" required governmental oversight and viewed boards of directors as part of management, rather than monitors for shareholders. The Securities and Exchange Commission (SEC) proposed that corporations establish a special board committee, made up of "nonofficer members" in response to the McKesson & Robbins scandal of the late 1930s. My dissertation examines the evolution of the U.S. corporate audit committee through three specific time periods: (1) 1920-1954; (2) 1955-1986; and (3) 1987 to the passage of the Sarbanes-Oxley Act of 2002. My purpose is to determine if evolution of the audit committee throughout these periods has been a reform continually couched in symbolism or whether the audit committee concept has evolved into real reform, allowing proper corporate governance and mitigation of unchecked corporate power. My analysis is a traditional empirical analysis, relying on both primary and secondary sources to develop a coherent ordering of facts. I use narrative …

The Rise and Fall of the Greenback Party in Texas: Economic Change and Political Dissent in the Post-Civil War Era
Access:
Use of this item is restricted to the UNT Community
In 1873, a financial crisis plunged the United States into a deep economic depression that exacerbated a number of post-war economic issues. By the late 1870s, political dissent centered primarily on financial issues merged into the Greenback movement, which represented a loose coalition of reformers calling for economic relief based on the expanded use of greenbacks (paper currency issued by the United States Treasury during the Civil War). The Greenback Party emerged as a direct response to federal financial policies, but in Texas, it also provided a broad political platform for those opposed to the policies of "Redeemer/Bourbon" Democrats. The Greenback Party of Texas brought together a wide range of dissenters, including disgruntled Democrats, ousted Republicans, and many different economic and social reformers. From 1876, when the first Greenback clubs appeared in Texas, to the Greenback Party's virtual disappearance after the election of 1884, the Texas Greenbackers reached across boundaries of section, race, class, and sometimes gender; brought together farmers, workers, and professionals; Southerners and Northerners, white and black; former Confederates and former Unionists; native-born Americans and immigrants; and received sizable support from multiple counties in the northern, eastern, and central part of the state. In spite of its short …

Evolution, Not Revolution: The Effect of New Deal Legislation on Industrial Growth and Union Development in Dallas, Texas
The New Deal legislation of the 1930s would threaten Dallas' peaceful industrial appearance. In fact, New Deal programs and legislation did have an effect on the city, albeit an unbalanced mixture of positive and negative outcomes characterized by frustrated workers and industrial intimidation. To summarize, the New Deal did not bring a revolution, but it did continue an evolutionary change for reform. This dissertation investigated several issues pertaining to the development of the textile industry, cement industry, and the Ford automobile factory in Dallas and its labor history before, during, and after the New Deal. New Deal legislation not only created an avenue for industrial workers to achieve better representation but also improved their working conditions. Specifically focusing on the textile, cement, and automobile industries illustrates that the development of union representation is a spectrum, with one end being the passive but successful cement industry experience and the other end being the automobile industry union efforts, which were characterized by violence and intimidation. These case studies illustrate the changing relationship between Dallas labor and the federal government as well as their local management. Challenges to the open shop movement in Dallas occurred before the creation of the New Deal, but …

Uncle Sam Does Not Want You: Military Rejection and Discharge during the World Wars
Access:
Use of this item is restricted to the UNT Community
In the United States, rapid military mobilization for the world wars marked a turning point in the national need to manage and evaluate manpower. To orchestrate manpower needs for the military, industry, and those relating to familial obligations, Woodrow Wilson's administration created the Selective Service System during the First World War. In categorizing men, local Selective Service boards utilized rapid physical and psychological diagnostic techniques and applied their assessments to current military branch induction standards to pronounce candidates as militarily fit or unfit. From World War I to World War II, the Selective Service System expanded as a bureaucracy but did not adequately address induction issues surrounding rapidly changing standards, racism, and inconsistent testing procedures. These persistent problems with Selective Service prevented the system from becoming truly consistent, fair, or effective. As a result of Selective Service System, War Department, and military branch standards, military rejection and prematurely military discharge rates increased in World War II. Additionally, though Selective Service did not accurately predict who would or would not serve effectively, rejected and prematurely discharged men faced harsh discrimination on the American home front during World War II.

The Nature of Cognitive Impairment in Multiple Sclerosis
Cognitive impairment is common in multiple sclerosis (MS), with as many as 70% of patients with MS affected. Individuals with MS who experience cognitive deficits are less likely to be employed, and may have more difficulty performing independent activities of daily living. Most commonly, deficits are observed in processing speed, complex attention, and memory. Because lesion location varies widely among individuals, no clear pattern of cognitive dysfunction in MS has emerged. However, a number of risk and protective factors may influence the likelihood of individuals to develop and/or express dysfunction, though the contribution of each to specific domains of cognition has not been fully explored. Recently, support for the cognitive reserve hypothesis (i.e., enriching life experiences protect against cognitive decline despite disease burden) has emerged in the MS literature. The current study investigated the contributions of cognitive reserve to learning and memory functioning in MS and the interaction of cognitive reserve variables and risk factors known to impact cognitive functioning in individuals with MS. Finding revealed cognitive reserve protects against decline in the domains of processing speed and complex attention. Furthermore, indirect protective effects of cognitive reserve through these domains were observed for verbal learning and memory. Finally, in line …

Between Comancheros and Comanchería: a History of Fort Bascom, New Mexico
In 1863, Fort Bascom was built along the Canadian River in the Eroded Plains of Territorial New Mexico. Its unique location placed it between the Comanches of Texas and the Comancheros of the Sangre de Cristo Mountains. This post was situated within Comanchería during the height of the United States Army's war against the Southern Plains Indians, yet it has garnered little attention. This study broadens the scholarly understanding of how the United States Army gained control of the Southwest by examining the role Fort Bascom played in this mission. This includes an exploration of the Canadian River Valley environment, an examination of the economic relationship that existed between the Southern Plains Indians and the mountain people of New Mexico, and an account of the daily life of soldiers posted to Fort Bascom. This dissertation thus provides an environmental and cultural history of the Canadian River Valley in New Mexico, a social history of the men stationed at Fort Bascom, and proof that the post played a key role in the Army's efforts to gain control of the Southern Plains Indians. This study argues that Fort Bascom should be recognized as Texas' northern-most frontier fort. Its men were closer to …

Feigning ADHD: Effectiveness of Selected Assessment Tools in Distinguishing Genuine from Simulated ADHD
Research indicates that some college students may be strongly motivated to feign AHDD symptoms for desired external incentives, such as stimulant medication or academic accommodations. To date, literature examining feigned ADHD has been primarily focused on ADHD specific self-report measures (e.g., CAARS) and continuous performance tests (e.g., CPTs); however, little attention has been devoted to the use of multi-scale inventories in detecting feigned ADHD. For CPT measures, virtually no literature exists on the effectiveness of the TOVA to identify feigned ADHD, despite its frequent clinical use for establishing this diagnosis. The current study utilized a between-subjects simulation design to validate feigning cut scores on ADHD-specific measures using 66 feigners and 51 confirmed ADHD cases. As prior literature suggested, the results convincingly demonstrated that face-valid ADHD assessment measures were easily faked. Across both TOVA modalities (e.g., Auditory and Visual), the ADHD simulators performed significantly poorer than those diagnosed with ADHD. As an innovative approach, a Dissimulation-ADHD (Ds-ADHD) scale was developed and initially validated. The Ds-ADHD is composed of ten MMPI-2-RF items mistakenly believed to be clinical characteristics associated with ADHD. Requiring cross-validation, Ds-ADHD optimized cut scores and classification of ADHD feigners appears promising. They were clearly distinguishable from ADHD client, as …
