The Monstrance: A Collection of Poems
These poems deconstruct Mary Shelley's monster from a spiritually Chthonian, critically post-structuralist creative stance. But the process here is not simple disruption of the original discourse; this poetry cycle transforms the monster's traditional body, using what pieces are left from reception/vivisection to reconstruct, through gradual accretion, new authority for each new form, each new appendage. digital.library.unt.edu/ark:/67531/metadc277686/
Monte Carlo Calculations of Reflected Intensities for Real Spherical Atmospheres
To calculate the emergent radiation field, a realistic atmospheric model and algorithm must be developed. The radiation field may be characterized by the emergent intensities of scattered light. This is possible only if the algorithm determines these intensities as dependent upon atmospheric and angular parameters. digital.library.unt.edu/ark:/67531/metadc131064/
Monte Carlo simulation and experimental studies of the production of neutron-rich medical isotopes using a particle accelerator.
Access: Use of this item is restricted to the UNT Community.
The developments of nuclear medicine lead to an increasing demand for the production of radioisotopes with suitable nuclear and chemical properties. Furthermore, from the literature it is evident that the production of radioisotopes using charged-particle accelerators instead of nuclear reactors is gaining increasing popularity. The main advantages of producing medical isotopes with accelerators are carrier free radionuclides of short lived isotopes, improved handling, reduction of the radioactive waste, and lower cost of isotope fabrication. Proton-rich isotopes are the result of nuclear interactions between enriched stable isotopes and energetic protons. An interesting observation is that during the production of proton-rich isotopes, fast and intermediately fast neutrons from nuclear reactions such as (p,xn) are also produced as a by-product in the nuclear reactions. This observation suggests that it is perhaps possible to use these neutrons to activate secondary targets for the production of neutron-rich isotopes. The study of secondary radioisotope production with fast neutrons from (p,xn) reactions using a particle accelerator is the main goal of the research in this thesis. digital.library.unt.edu/ark:/67531/metadc3077/
The Moore-Smith Limit
It is the purpose of this thesis to indicate in more detail how various limits defined in analysis, as well as other concepts not ordinarily defined as limits, may be obtained as special cases of the Moore-Smith limit. digital.library.unt.edu/ark:/67531/metadc107833/
The Moral Judgments of Jane Austen
It is the purpose of this thesis to examine the relevance of Jane Austen's moral and social judgments for the twentieth century, in terms of insight into human nature and human relationships and of a realistic and penetrating treatment of the moral and social problems most vital to moiety in the 1960's. digital.library.unt.edu/ark:/67531/metadc131032/
The Moral Philosophy of James Boswell
It is the purpose of the author to outline briefly some of the intellectual ideas relating to the nature of man, his conception of religion, his social manners and customs, and to reveal, through the "Hypochondriack" essays, that James Boswell was a peculiarly eighteenth-century figure in certain aspects of his moral philosophy. digital.library.unt.edu/ark:/67531/metadc83431/
The Moral Philosophy of Samuel Johnson
The purpose of the author is to give a resume of Johnson's England and by examining The Rambler and Boswell's Life of Johnson, to determine what the Doctor thought concerning the prevailing conditions, social practices, and ideas of his time. digital.library.unt.edu/ark:/67531/metadc83584/
Moral Training for Nature's Egotists: Mentoring Relationships in George Eliot's Fiction
George Eliot's fiction is filled with mentoring relationships which generally consist of a wise male mentor and a foolish, egotistic female mentee. The mentoring narratives relate the conversion of the mentee from narcissism to selfless devotion to the community. By retaining the Christian value of self-abnegation and the Christian tendency to devalue nature, Eliot, nominally a secular humanist who abandoned Christianity, reveals herself still to be a covert Christian. In Chapter 1 I introduce the moral mentoring theme and provide background material. Chapter 2 consists of an examination of Felix Holt, which clearly displays Eliot's crucial dichotomy: the moral is superior to the natural. In Chapter 3 I present a Freudian analysis of Gwendolen Harleth, the mentee most fully developed. In Chapter 4 I examine two early mentees, who differ from later mentees primarily in that they are not egotists and can be treated with sympathy. Chapter 5 covers three gender-modified relationships. These relationships show contrasting views of nature: in the Dinah Morris-Hetty Sorrel narrative, like most of the others, Eliot privileges the transcendence of nature. The other two, Mary Garth-Fred Vincy and Dolly Winthrop-Silas Marner, are exceptions as Eliot portrays in them a Wordsworthian reconciliation with nature. In Chapter 6 I focus on Maggie Tulliver, a mentee with three failed mentors and two antimentors. Maggie chooses regression over growth as symbolized by her drowning death in her brother's arms. In Chapter 7 I examine Middlemarch, whose lack of a successful standard mentoring relationship contributes to its dark vision. Chapter 8 contains a reading of Romola which interprets Romola, the only mentee whose story takes place outside nineteenth-century England, as a feminist fantasy for Eliot. Chapter 9 concludes the discussion, focusing primarily on the question why the mentoring theme was so compelling for George Eliot. In the Appendix I examine the relationships in Eliot's life in which she herself was a mentee or a mentor. digital.library.unt.edu/ark:/67531/metadc2868/
Morale in the Western Confederacy, 1864-1865: Home Front and Battlefield
Access: Use of this item is restricted to the UNT Community.
This dissertation is a study of morale in the western Confederacy from early 1864 until the Civil War's end in spring 1865. It examines when and why Confederate morale, military and civilian, changed in three important western states, Mississippi, Alabama, and Tennessee. Focusing on that time frame allows a thorough examination of the sources, increases the opportunity to produce representative results, and permits an assessment of the lingering question of when and why most Confederates recognized, or admitted, defeat. Most western Confederate men and women struggled for their ultimate goal of southern independence until Federal armies crushed those aspirations on the battlefield. Until the destruction of the Army of Tennessee at Franklin and Nashville, most western Confederates still hoped for victory and believed it at least possible. Until the end they drew inspiration from battlefield developments, but also from their families, communities, comrades in arms, the sacrifices already endured, simple hatred for northerners, and frequently from anxiety for what a Federal victory might mean to their lives. Wartime diaries and letters of western Confederates serve as the principal sources. The dissertation relies on what those men and women wrote about during the war - military, political, social, or otherwise - and evaluates morale throughout the period in question by following primarily a chronological approach that allows the reader to glimpse the story as it developed. digital.library.unt.edu/ark:/67531/metadc5231/
Morality and Mortality: the Role of Values in the Adoption of Laws Governing the Involuntary Removal of Life Sustaining Medical Treatment in Us States
Disputes between patients and providers regarding life-sustaining medical treatment (LSMT) are universal across all U.S. states, yet policies regarding these disputes differ significantly. This dissertation determines that all 50 states have advance directive laws that protect a patient’s right to refuse LSMT even when a healthcare provider objects, yet only some states have policies that protect the patient’s right to choose to continue LSMT when a healthcare provider objects (a dispute known as medical futility). Some states have pro-patient laws that protect the patient’s right to make the final decision, while other states have enacted pro-provider medical futility policies that explicitly grant the provider authority to remove LSMT against the patient’s wishes. Finally, in one state, the law delegates the final decision to a third-party: institutional healthcare ethics committees. This dissertation studies the innovation and adoption of these 17 state medical futility policies, examining the theory that values determine both whether the state adopts a medical futility policy as well as what type of medical futility policy a state will adopt- as the policy actors that represent these values: policy entrepreneurs and interest groups. A comparative case study of successful third-party policy adoption in Texas contrasted against a failed effort in Idaho could not affirm the necessity of policy entrepreneurs for policy adoption but did affirm the necessity of interest group consensus and the role of values. Furthermore, quantitative analysis failed to offer statistically-significant evidence of value indicators, but did suggest that government ideology and political party affiliation may potentially become indicators of the type of medical futility policy that states choose to adopt. digital.library.unt.edu/ark:/67531/metadc149554/
The Morality and Wit of Congreve and Sheridan in the Comedy of Manners
Considering the comedies of the Restoration, and those of Congreve in particular, as the prototype of the comedy of manners and as the model for Sheridan later to revive and emulate, this thesis proposes to point out how the concepts of morality and wit have been a major obstacle to literary critics in analyzing the comedy of manners from its very beginnings, to discuss morality and wit as the basis of a proper evaluation of the comedy of manners both from the standpoint of seventeenth-century precepts and those of a century later, and, finally, to show how, during the early periods in which the comedy of manners flourished,--that of Congreve, 1693-1700; and of Sheridan, 1775-1779--morality and wit were modified and used to suit the divergent sociological and psychological conditions of each period. digital.library.unt.edu/ark:/67531/metadc107994/

More buildings about songs and food: A case study of Omaha's Slowdown project.
The success of independent rock music ("indie rock"), once a marginalized sub-genre of the rock idiom and now a globally recognized cultural force, has impacted the urban landscape of Omaha, Nebraska via the mixed-use urban redevelopment project, "Slowdown" - a result of cultural production by the city's successful indie rock business entities. While geographic research has previously analyzed urban redevelopment initiated by fine artists, the event of indie rock music being a catalyst for urban redevelopment has never been considered in a geographic scope. By examining the topics of affordable technological tools, Omaha's reduced cost-of-living, and cooperative efforts by city leaders, insight into how an indie rock "scene" can become a successful urban redevelopment catalyst is gained. digital.library.unt.edu/ark:/67531/metadc3917/
More connections, less connection: An examination of the effects of computer-mediated communication on relationships.
The impact of computer-mediated communication (CMC) on relational behavior is a topic of increasing interest to communication scholars (McQuillen, 2003; Tidwell & Walther, 2002). One of the most interesting issues that CMC raises concerns the impact of CMC on relational maintenance and development. Using dialectical theory, social exchange theory, social information processing theory, and the hyperpersonal perspective as theoretical frameworks, this study used quantitative and qualitative analyses to identity potential effects of CMC on relationships. Study 1 (n=317) examined the effects of CMC on relational closeness, satisfaction, and social support. Study 2 (n=196) explored the reasons individuals provide for privileging computer-mediated forms of communication, and the perceived effects of using CMC in relational communication. Results indicated that quality of CMC predicted increased perceptions of social support and relationship satisfaction. Results further suggested that CMC enabled participants to manage more effectively relational tensions of autonomy-connection and openness-closedness. Specifically, individuals used CMC to retain higher levels of conversational control, and to maintain greater numbers of relationships with decreased levels of investment. This paper concludes with a discussion of implications and directions for future research. digital.library.unt.edu/ark:/67531/metadc5449/
Morning and Afternoon Response to Exercise Using Two Test Protocols
The purpose was to investigate time of day on responses to two types of exhaustive cycle ergometer tests. Sixteen males performed six exercise tests: three - constant power protocol and three - incremental protocol. The first test was a learning trial; the other tests were performed one in the morning and one in the afternoon. ANOVA revealed that O2 deficit and lactate were higher in the afternoon than the morning. Regardless of test type, time to exhaustion tended to be higher in the afternoon. VO2max was unaffected by the time of day and test type. These results confirmprevious reports of a time of day effect on anaerobic capacity, and support the contention that V02max is stable about a day. digital.library.unt.edu/ark:/67531/metadc277988/
Morphological and Hematological Responses to Hypoxia During Development in the Japanese quail, Coturnix coturnix
Hypoxic responses in quail development differ depending upon stage, duration and level of oxygen partial pressure of embryo. Incubation was switched to/from 110mmHg partial pressure (hypoxia), to/from 150mmHg (normoxia) during different stages in development, and control was incubated in normoxia throughout. Hatchability and embryo survival resulted in no hatchlings in continuous hypoxia. Responses to various hypoxic exposures throughout development resulted in recovery/repair of hypoxic damage by hatch. Heart and body mass, beak and toe length, hemoglobin, and hematocrit were measured to determine embryo responses to hypoxia during development at days 10, 15, and hatch. Hypoxia seemed to have the most deleterious effects on eggs in continuous hypoxia. Collectively, data indicate critical developmental windows for hypoxia susceptibility, especially during mid-embryonic development. digital.library.unt.edu/ark:/67531/metadc4222/
Morphological and Physiological Changes in Micrococcus Pyogenes Var. Aureus during Development of its Resistance to Terramycin
The problem in this investigation consists of, first, the procurement of several strains of Micrococcus pyogenes var. aureus; second, the comparison of the degree and rate of development of resistance of these organisms to terramycin; and, third, to study the morphological and physiological changes which occur during the development of resistance. digital.library.unt.edu/ark:/67531/metadc130350/
Morphological and physiological developmental consequences of parental effects in the chicken embryo (Gallus gallus domesticus) and the zebrafish larva (Danio rerio).
Cardiac, metabolic and growth response of early-stage chicken embryos to perturbations in yolk environment was investigated. Also, effects of parental hypoxia exposure on hypoxia resistance, thermal tolerance and body length of zebrafish larvae were investigated. In the first study, thyroxine, triiodothyronine and testosterone produced differential effects on heart rate and development rate of chicken embryos during the first 4 days of development. Triiodothyronine caused a dose-dependent increase in heart rate when applied at 40 or 70 hours of age, while thyroxine caused a dose-dependent increase in heart rate when applied at 40 hours only. Testosterone and propyl-thiouracil (deiodinase antagonist) did not have an effect on heart rate. Development rate was not changed by thyroxine, triiodothyronine, testosterone or propyl-thiouracil, which suggested that heart rate changes did not result from changes in embryo maturity. In the second study, chicken embryos exposed to yolks of different bird species during early-stage embryonic development showed changes in heart rate, mass-specific oxygen consumption and body mass that scaled with the egg mass, incubation period length, and yolk triiodothyronine and testosterone levels of the species from which yolk was derived. In the third study, this phenomenon was investigated between layer and broiler chickens. Heart rate, oxygen consumption and body mass of broiler and layer embryos were significantly changed by a breed-specific change in yolk environment. Yolk triiodothyronine and testosterone concentrations of broiler and layer eggs did not suggest that these hormones were responsible for physiological and morphological changes observed. The final study demonstrated that hypoxia resistance and body lengths, but not thermal tolerance of zebrafish larvae was increased by parental hypoxia exposure. digital.library.unt.edu/ark:/67531/metadc9086/
Morphological properties of poly (ethylene terephthalate) (PET) nanocomposites in relation to fracture toughness.
The effect of incorporation of montmorillonite layered silicate (MLS) on poly (ethylene terephthalate) (PET) matrix was investigated. MLS was added in varying concentration of 1 to 5 weight percent in the PET matrix. DSC and polarized optical microscopy were used to determine the crystallization effects of MLS addition. Non isothermal crystallization kinetics showed that the melting temperature and crystallization temperature decrease as the MLS percent increases. This delayed crystallization along with the irregular spherulitic shape indicates hindered crystallization in the presence of MLS platelets. The influence of this morphology was related with the fracture toughness of PET nanocomposites using essential work of fracture coupled with the infra red (IR) thermography. Both the essential as well as non essential work of fracture decreased on addition of MLS with nanocomposite showing reduced toughness. digital.library.unt.edu/ark:/67531/metadc4845/
A morphological study of the avian (Gallus domesticus) ductus arteriosi during hatching.
Access: Use of this item is restricted to the UNT Community.
The ductus arteriosi (DA) are two blood vessels connecting the pulmonary arteries to the descending aorta in the avian embryo. Following hatching, the DA closes, separation of the systemic and pulmonary circulation. I present the morphological changes that occur in the chicken DA during prepipping, internal pipping, external pipping, and hatching. The avian DA consists of two distinct tissue types, a proximal and a distal portion. Histological examination shows developmental differences between the proximal and distal portions of the DA with regard to lumen occlusion, endothelial cells, smooth muscle and elastin. Endothelial cell proliferation begins to occur as early as external pipping, with the lumen almost completely occluded by the 3rd day of post-hatching life. Expression of vascular endothelial growth factor (VEGF) increases in avian endothelial cells during hatching. I provide a morphological timeline of changes in the DA as the chicken develops from embryo to hatchling. digital.library.unt.edu/ark:/67531/metadc5233/
Mosques in France: The Visible Presence of Islam
Numerous laws are being directed toward subduing the visible presence of Islam throughout France, and in return French Muslims are becoming bolder in the projection of their faith. This thesis examines the presence of Islam in France throughout history and in contemporary French civilization. Specifically, this thesis addresses the issues regarding the visible presence of Islam in France through such institutions as mosques and how they are the key symbols representing the prominence of Islam in France. It looks at what lies in the collective French mind that creates such an influence on today's policies and outlook, as well as identifies the key characters that dominate the current affairs surrounding Islam in France. The thesis reviews the country's past relations with the visible presence of Islam through the controversies surrounding the construction of famous mosques. In addition, this thesis underlines key areas where both the State and the Muslim population must make concessions in order to avoid further conflict. digital.library.unt.edu/ark:/67531/metadc67957/
The Most Important Educational Problems Affecting the Growth of Elementary Schools of Texas, 1972
The problem with which this investigation is concerned is the identification of conditions, situations, and events that are important problems faced in the public elementary schools of Texas. Problems are categorized into sixteen areas: finance, desegregation and busing, school organization, school personnel, preschool and kindergarten, instructional improvement, reporting systems, pupil behavior, curriculum, in-service staff training, humanizing the schools, public relations, minority groups, migrant children, special education, and recent trends. The purpose of the study is to determine perceived importance of problems and to establish priorities of current issues from information obtained from education leaders of elementary schools. digital.library.unt.edu/ark:/67531/metadc164583/
Mother-child Relations and Social Expectations of Normal Children and Those with Learning Disabilities
The study explored the possibility that the perceived mother-child relationship of children with learning disabilities differs from that of normal children. It was further hypothesized that the manner in which the child perceives his relationship to his mother is related to the perception he has of his society in general. digital.library.unt.edu/ark:/67531/metadc164090/
Mothers' and Fathers' Parenting Characteristics in Relation to Family Earner Status and Self-perceived Interpersonal Competence
With an increasing number of married mothers who participated in paid work roles, fathers with full-time employed spouses now are expected to assume the role of caregiver and have higher frequency of engagement in parenting practices. This study of 235 university students from dual-earner and single-earner families investigated their retrospective perceptions of both mothers' and fathers' frequency of engagement in overall and specific parenting behaviors. These perceptions were measured by the Parent Behavior Frequency Questionnaire-Revised Scale, which includes seven parenting characteristics and related behaviors. Paired samples t-tests suggested that married mothers, whether fully employed outside the home or not, engaged more frequently, than their full-time employed spouses, in parenting characteristics related to bonding, education, general welfare and protection, responsivity, and sensitivity. However, mothers' employment status had little influence upon the frequency at which either parent engaged in any of the seven parenting characteristics and related behaviors. University students who perceived that both parents were more frequently engaged in specific parenting behaviors related to education, responsivity and sensitivity rated themselves higher on interpersonal competence, as measured by the Interpersonal Competence Questionnaire-Revised Scale. Students who perceived that both parents were less frequently engaged in negative parenting behaviors rated themselves higher on competence in conflict management. In addition, family earner status had no significant impact on university students' levels of interpersonal competence. Although there was no significant gender difference in the levels of total interpersonal competence, male students reported higher levels of interpersonal competence in the domains of asserting influence and conflict management than their female counterparts. These findings revealed that like parents from single-earner families, parents from dual-earner families also demonstrated a significant discrepancy in the frequency of engagement in parenting practices. Mothers still invested considerably more time with their children than do fathers. Therefore, there may be a need to develop parent education programs for fathers so that they have opportunities to shape paternal identity and parental self-efficacy. Also, it is necessary to develop friendly family- employment policies and enhance social support networks that enable both full-time employed mothers and fathers to achieve a satisfactory balance between family and work. digital.library.unt.edu/ark:/67531/metadc177184/
Mothers as Play Therapists for their Children
The problem with which this investigation is concerned is that of determining whether previously untrained, non-professional personnel, in this case mothers, can be trained to undertake and cope with the responsibilities of a play therapy situation with their own children. The hypothesis of this study is that by placing mothers in such a situation, the mother's ability to communicate with her child will be modified as well as modifying the child's perception of her as a warm and accepting parent. digital.library.unt.edu/ark:/67531/metadc131330/
Mothers' Perceptions and Preschoolers' Experiences: Cultural Perspectives of Early Childhood Education
In this qualitative investigation, the ways in which four ethnically diverse mothers' perceptions of early childhood education combined with the school experiences of their children were examined. Research tools included audiotaped interviews with Mexican-American, Korean-American, African-American, and Anglo mothers; videotaped school experiences; and a video message with a viewing guide requesting written reaction. digital.library.unt.edu/ark:/67531/metadc278495/
Motion Versus Non-Motion in Interactive Video Lessons in High School Physical Science
The most important question addresed in this study was whether there is any difference in student learning between a motion group and a non-motion group. The interactive video courseware is currently a part of the curriculum in this district. It was used in its original form with the contrast group. For the experimental group one unit of the courseware was modified to remove the motion video and replace it with photorealistic graphics that served as the non-motion part of the study. Covariates were selected to compensate for any differences in the two groups. A pretest and posttest was administered to both groups. Analysis of the posttest scores indicated that there was no difference in learning if motion in the presentation was the only variable. digital.library.unt.edu/ark:/67531/metadc279141/
Motivating Factors for Philanthropy at a Ministry Preparation Graduate Institution
A qualitative case study was conducted to determine whether major donors to an institution of higher education that existed to prepare ministers and missionaries were perceived by the institution's leaders as motivated by organizational effectiveness, financial efficiency, or evaluations by donor watchdog agencies. The case study was conducted with the Graduate Institute of Applied Linguistics. The interview process was utilized to gain information individually from the president, a development consultant, an academic dean, and a former development director. Each participant was asked a series of 19 questions during the interview process. The results indicated that the leaders perceived that organizational effectiveness was a philanthropic motivator for major donors and measured it by the accomplishments of those who were trained at the institution. The results also indicated that the ministry preparation institution's leaders perceived financial efficiency to provide philanthropic motivation to major donors, though to a lesser degree than organizational effectiveness, and measured it by stewardship of funds. The results further indicated that the ministry preparation institution's leaders perceived that donor watchdog agency evaluations, specifically those of the Evangelical Council for Financial Accountability and Guidestar, provided philanthropic motivation for major donors. Additional research recommendations included studying how to report about organizational effectiveness in a manner meeting the needs of major donors and what motivates major donors of other education and nonprofit organizations, organizational effectiveness and/or financial efficiency. digital.library.unt.edu/ark:/67531/metadc271886/
Motivation and Resilience in Art Education: Insight and Inspiration From the Lives and Careers of Two Taiwanese College Art Teachers
Access: Use of this item is restricted to the UNT Community.
This narrative study explores how two Taiwanese college art teachers’ lives and teaching experiences illustrate the ways they cultivate resilience and motivation to sustain professional commitments amidst challenges in their teaching careers. I use the life story interview as my methodology and a three-dimensional space approach to code and analyze my data to retell their stories about how resilience and motivation have guided them as they negotiated dilemmas in teaching. The participants’ stories demonstrate that in order to be motivated, teachers must satisfy their basic needs, which, in the language of Maslow’s need theory, include secure income, safety, love and belonging, respect, and personal accomplishment. To be resilient, art teachers need to facilitate self-efficacy as an essential belief to face challenges, and they also must gain support from family members, students, school administrators, and fellow members of professional organizations as external support resources. This study also illuminates the significance of international educational exchanges, the teaching knowledge constructed through layers of life and professional experience, and the importance of creating dialogue to address teachers’ challenges. Recommendations for future study include exploring further the relationship between motivation and resilience, specifying how gender difference affects the ways participants tell their stories, investigating how teachers in diverse cultural and geographical settings develop motivation and resilience, considering how teachers construct career-affirming memories from both positive and negative life experiences, and exploring uses of social media to engage a broader audience, sharing participants’ stories without the limitations of time and space. digital.library.unt.edu/ark:/67531/metadc149570/
The Motivation of Characters in Othello, King Lear and Macbeth
By examining the critical comment of some of the best known critics, who fall roughly into two groups, the philosophical or psychological on the one hand, and the realistic on the other, I have endeavored to gather the ideas they have advanced in regard to the motives of them main characters from three of Shakespeare's tragedies--Othello, King Lear, and Macbeth. It is evident that the discussion of motives has not been the main consideration of any one of them, though the problem has naturally arisen in the analyses of characters and explanations of plot and dramatic art. Consequently it will be my purpose to study these plays from the standpoint of the motivation of the characters, having in mind two objects: the determination of which motives Shakespeare took from the sources of the plays and which ones he himself attributed to the characters, and the determination of which group of critics, the psychological or the realistic, is more nearly correct in their contentions in regard to the motivation of characters in Shakespeare's plays. digital.library.unt.edu/ark:/67531/metadc75359/
Motivational Differences between High and Low Normal Groups
The need for a concise definition of the normal, healthy personality prompted a study of high normal and low normal students enrolled at North Texas State University. Such a definition would facilitate the activities of several areas of applied psychology--psychotherapy, quantification of objective means of rating the general health of an individual's personality, the development of criteria against which to measure the success of mental health clinic programs. digital.library.unt.edu/ark:/67531/metadc130556/

The study was designed to obtain feedback about existing and future incentive programs that will enhance development of a positive working environment, along with higher productivity and a lower turnover rate. digital.library.unt.edu/ark:/67531/metadc278724/
Motives, Allusions, and Eclecticism: A Panametric Analysis of the First Movement of Christian Lindberg's Mandrake in the Corner based on the Method of Jan LaRue
For more than 20 years, Christian Lindberg has been internationally recognized as the premiere trombone soloist of our time. Few, however, are familiar with his compositions. For over ten years, he has composed many solo and ensemble works for trombone. Many prominent musical organizations in the world have performed Lindberg's music, including the Chicago Symphony Orchestra, the St. Paul Chamber Orchestra, and the University of North Texas Wind Ensemble. Today, Christian Lindberg has commission requests up to 2010. Christian Lindberg completed Mandrake in the Corner, a three movement concerto for trombone, in 1999. The purpose of this dissertation is to present an analysis of the first movement of Mandrake in the Corner to provide the first in depth study of Lindberg's compositional style. This analysis borrows freely from the method of Jan LaRue, which focuses on sound, harmony, melody, rhythm, and growth of musical structure on the small, middle, and large levels. The focus of this study centers on the aspects of melody, harmony, and rhythm to explain how the piece works despite the lack of a second theme or change of key in the first movement. digital.library.unt.edu/ark:/67531/metadc3603/
Motivic development in the piano music of Karl Weigl (1881-1949).
In discussing the music of Karl Weigl (1881-1949), it is essential to estimate the state of research regarding the composer and his professional life. Although a copious account and collection of Weigl's papers exists at Yale University, much contribution in the form of editions, recordings, and scholarly texts is needed. Schooled by Adler, Schoenberg, and Zemlinsky, Weigl graduated from the Musikacademie of Vienna in 1899 with high honors, with later employment in the Vienna Opera as a vocal coach (where he worked with such figures as Bruno Walter, Friedrich Weidemann, and Lotte Lehmann.). A theory and composition appointment to the New Vienna Conservatory after 1918 dramatically opened Weigl's professional horizons. With the rise of anti-semitism in Nazi Germany, Weigl and his family escaped to New York in autumn 1938. Eventually, Weigl obtained positions in the Hartt School of Music, Brooklyn College, Boston Conservatory, and finally, the Philadelphia Academy of Music in 1948. Although Weigl's music has been commented upon by Stephen Davison, Wendell Davis, and Michael Kater, much literature in the form of published analysis, commentary, and biography has yet to come forward. This paper principally covers Weigl's Night Fantasies, Op. 13 as well as the 28 Variations for Piano, Op. 15 and the expressionist conventions they contain. digital.library.unt.edu/ark:/67531/metadc5175/
Mouse cortical cholinergic neurons: Ontogeny of phenotypes in vivo and in vitro.
The development of cholinergic neurons in mouse frontal cortex was studied both in vivo and in vitro by immunocytochemistry with an antibody to choline acetyltransferase (ChAT), the enzyme responsible for acetylcholine synthesis. While cortical cholinergic neurons have previously been characterized in rat cortex, up until very recently, intrinsic cortical cholinergic neurons were considered to be absent in mouse, and little is known about their development or phenotypic characteristics. The present study found no ChAT-positive neurons in mouse frontal cortex on postnatal day 0 (P0, the day of birth). On P7 there were few, faintly stained, ChAT-positive neurons. The numerical density of ChAT-positive neurons increased substantially with age, from none on P0, to 9.2 + 1.4 on P7, to 14.8 + 0.9 on P16, and 41.6 + 3.9 in adulthood. Considering that the numerical density of total neurons decreases during this postnatal period, the data represent a marked developmental increase in the percentage of cholinergic neurons. The development of cholinergic neurons showed very similar timelines in rat and mouse frontal cortex. Cultures prepared from mouse frontal cortex on embryonic day 16 were maintained for 25, 76, or 100 days in vitro (div). The percentage of ChAT-positive neurons was considerably higher than in vivo, ranging from a mean 28% to 31% across the three age (div) groups. With increasing age of the cultures, the numerical density of total neurons and ChAT-positive neurons decreased while the percentage of ChAT-positive neurons did not change significantly. These observations suggest some temporal stability in the cultures. Using dual immunofluorescence, ChAT-positive neurons were tested for colocalization with GAD or TH. The majority of ChAT-positive neurons colocalized with GAD, both in vitro and in vivo. However, ChAT did not colocalize with TH, either in vitro or in vivo. Our comparison of intact frontal cortex and cultures suggest that while the percentage of cholinergic neurons was greater in the cultures, the cholinergic neurons developed phenotypic similarities in vitro and in vivo. digital.library.unt.edu/ark:/67531/metadc4890/

Moving in a New Direction: An Exploration in Kinetics
Movement, whether conveyed through an actual motion or a gestured implication, remains an underlying theme in my creative process that started with my earliest works. I explored different aspects of kinetic sculpture, because I am seeking new ways to create motion such as experimenting with circulating air, wind, and the use of water features. I created a series consisting of three to five kinetic sculptures which do not rely on sound or direct viewer manipulation. digital.library.unt.edu/ark:/67531/metadc4482/
Moving toward the 21st Century: American Association of Colleges of Nursing Guidelines and Baccalaureate Nursing Education
This study investigated current use of American Association of Colleges of Nursing guidelines in preparing the baccalaureate nurse graduate to practice nursing in the community health sector of the healthcare delivery system and use of community based healthcare delivery sites by baccalaureate programs located in non-urbanized and urbanized areas. The extent of guidelines adoption, plans by colleges not currently using them to do so in the future, and impact of accreditation visits on the adoption of the guidelines were also explored. A qualitative survey design was used to describe the use of AACN guidelines in the development of baccalaureate nursing education. digital.library.unt.edu/ark:/67531/metadc278423/
Mozartean Gesture and Rhetoric in Hummel's Concerto for Trumpet
Hummel's Concerto for Trumpet (Concerto a Tromba principale) is overtly operatic and is stylistically reminiscent of Mozart's Don Giovanni. Using the methodology of Leonard Ratner and Wye J. Allanbrook, it is possible to explore gesture and rhetoric in Hummel's Concerto for Trumpet and Mozart's Don Giovanni, and achieve a deeper understanding of the stylistic similarities shared between the two works. In the third movement, dance is the most significant link to Don Giovanni. In the second movement, Hummel alternates between the emotions of Donna Anna and Don Ottavio as they appear in act 1, scene 13. The first movement makes extensive use of contrasting topics identified with buffa and seria characters to advance the musical narrative. Comparing Hummel's concerto and Mozart's opera is a hermeneutical approach that illuminates several performance practice implications. Knowing the expressive similarities and rhetorical strategies common to both works clarifies several issues, such as tempo, ornamentation, and above all, expression. Though Mozart's Don Giovanni and Hummel's Concerto for Trumpet are unequal in significance, it would be valuable to any interpretation of Hummel's concerto if the performer and audience acknowledge that the work is rhetorically and stylistically similar to Mozart's Don Giovanni. digital.library.unt.edu/ark:/67531/metadc6062/
Mr Secrets and Social Media: the Confession of Richard Rodriguez
Richard Rodriguez's works create troubling situations for many scholars. Though numerous critics see him as the penultimate Chicano writer, many others see his writing as only pandering to the elite. However, all politics and controversies aside, he is a writer whose ideas upon language and public confession have been revolutionary. Throughout the thesis, I argue that Rodriguez's ideas upon language and identity are applicable to the social media landscape that we reside in currently, especially the public confession. Also, I use deconstructionism, along with postmodern criticism, to illustrate the changing arc of Rodriguez's confession from his first autobiography to his final one. In his first memoir, Rodriguez remains in the closet upon his sexuality, and the reader only catches glimpses of the 'real' character inside his work. In the second memoir, the reader sees a better glimpse because of his coming out; yet, even in this regard, he does not do so wholly and still leaves his confession unfinished. By the third, he applies themes and problems seen in his first and second works to discuss our browning nature, and how we are all sinners and that we desire to confess our sins. In my assessment of Rodriguez, I argue throughout all my chapters upon a measure of irreconcilability between the private world of the Hispanic immigrant family and the public sphere that they are forced to inhabit because of his citizenship and education. This irreconcilability creates a drastic limiting of identity for the author that Rodriguez is forced to navigate which creates his desire for confession. digital.library.unt.edu/ark:/67531/metadc271788/
Muerte Y Soledad En La Poesía De Manuel Altolaguirre Ante El Exilio
This study focuses on the Spanish poet of the Generation of '27 Manuel Altolaguirre. The purpose of this thesis is to show how the poetry of Manuel Altolaguirre evolves in relation to specific issues. Specifically, I study the changes in his work in regard to the themes of death and solitude, resulting from exile in 1939, to be enriched by new experiences, many of them dramatic, taking more personal ways, while offering them a more profound and complex and even in regard to the subject of the poet's death comes to contemplate a more positive way. The thesis is divided into five chapters. Following the introduction, the second chapter focuses on Altolaguirre's biography and the Generation in 1927 while the third focuses and analyzes his poetry before his exile in 1939. The fourth chapter examines his poetry after exile until his death in 1959, while the fifth and last chapter concludes this study. digital.library.unt.edu/ark:/67531/metadc271861/
Multi-Agent Architecture for Internet Information Extraction and Visualization
Access: Use of this item is restricted to the UNT Community.
The World Wide Web is one of the largest sources of information; more and more applications are being developed daily to make use of this information. This thesis presents a multi-agent architecture that deals with some of the issues related to Internet data extraction. The primary issue addresses the reliable, efficient and quick extraction of data through the use of HTTP performance monitoring agents. A second issue focuses on how to make use of available data to take decisions and alert the user when there is change in data; this is done with the help of user agents that are equipped with a Defeasible reasoning interpreter. An additional issue is the visualization of extracted data; this is done with the aid of VRML visualization agents. The cited issues are discussed using stock portfolio management as an example application. digital.library.unt.edu/ark:/67531/metadc2575/
Multi-Channel Retailing: Function of Consumers' Perceived Benefits and Costs and Retail Synergy
This study investigated the consumers' intention towards multi-channel shopping and the function of synergy in a multi-channel retailing format (i.e., brick-and-mortar stores, catalogs, and the Internet). Two questionnaires were developed, one for the multi-channel consumers and the other for the multi-channel retailers. The structural equation modeling was used to predict the effect of shopping benefits and costs perceived from each channel on the consumer's purchase intention. Data analysis (N = 500) indicated that the purchase intentions were affected by different shopping benefit and cost variables. Qualitative analysis of retailers (N= 10) revealed that the retailers considered synergy to be an important part of their multi-channels. Also, there existed a high level of synergy among the existing three retail channels. digital.library.unt.edu/ark:/67531/metadc4188/
A multi-dimensional entropy model of jazz improvisation for music information retrieval.
Jazz improvisation provides a case context for examining information in music; entropy provides a means for representing music for retrieval. Entropy measures are shown to distinguish between different improvisations on the same theme, thus demonstrating their potential for representing jazz information for analysis and retrieval. The calculated entropy measures are calibrated against human representation by means of a case study of an advanced jazz improvisation course, in which synonyms for "entropy" are frequently used by the instructor. The data sets are examined for insights in music information retrieval, music information behavior, and music representation. digital.library.unt.edu/ark:/67531/metadc4929/
Multi-perspective, Multi-modal Image Registration and Fusion
Multi-modal image fusion is an active research area with many civilian and military applications. Fusion is defined as strategic combination of information collected by various sensors from different locations or different types in order to obtain a better understanding of an observed scene or situation. Fusion of multi-modal images cannot be completed unless these two modalities are spatially aligned. In this research, I consider two important problems. Multi-modal, multi-perspective image registration and decision level fusion of multi-modal images. In particular, LiDAR and visual imagery. Multi-modal image registration is a difficult task due to the different semantic interpretation of features extracted from each modality. This problem is decoupled into three sub-problems. The first step is identification and extraction of common features. The second step is the determination of corresponding points. The third step consists of determining the registration transformation parameters. Traditional registration methods use low level features such as lines and corners. Using these features require an extensive optimization search in order to determine the corresponding points. Many methods use global positioning systems (GPS), and a calibrated camera in order to obtain an initial estimate of the camera parameters. The advantages of our work over the previous works are the following. First, I used high level-features, which significantly reduce the search space for the optimization process. Second, the determination of corresponding points is modeled as an assignment problem between a small numbers of objects. On the other side, fusing LiDAR and visual images is beneficial, due to the different and rich characteristics of both modalities. LiDAR data contain 3D information, while images contain visual information. Developing a fusion technique that uses the characteristics of both modalities is very important. I establish a decision-level fusion technique using manifold models. digital.library.unt.edu/ark:/67531/metadc149562/
The Multi-reference Correlation Consistent Composite Approach: A New Vista In Quantitative Prediction Of Thermochemical And Spectroscopic Properties
The multi-reference correlation consistent composite approach (MR-ccCA) was designed to reproduce the accuracy of more computationally intensive ab initio quantum mechanical methods like MR-ACPF-DK/aug-cc-pCV?Z-DK, albeit at a significantly reduced cost. In this dissertation, the development and applications of the MR-ccCA method and a variant of its single reference equivalent (the relativistic pseudopotential ccCA method) are reported. MR-ccCA is shown to predict the energetic properties of reactive intermediates, excited states species and transition states to within chemical accuracy (i.e. ±1.0 kcal mol 1) of reliable experimental values. The accuracy and versatility of MR-ccCA are also demonstrated in the prediction of the thermochemical and spectroscopic properties (such as atomization energies, enthalpies of formation and adiabatic transition energies of spin-forbidden excited states) of a series of silicon-containing compounds. The thermodynamic and kinetic feasibilities of the oxidative addition of an archetypal arylglycerol ?-aryl ether (?-O-4 linkage) substructure of lignin to Ni, Cu, Pd and Pt transition metal atoms using the efficient relativistic pseudopotential correlation consistent composite approach within an ONIOM framework (rp-ccCA-ONIOM), a multi-level multi-layer QM/QM method formulated to enhance the quantitative predictions of the chemical properties of heavy element-containing systems larger than hitherto attainable, are also reported. digital.library.unt.edu/ark:/67531/metadc103368/
A multi-state political process analysis of the anti-testing movement.
I applied McAdam's political process model for social movement analysis to examine the level of collective resistance to high stakes testing in California, Massachusetts, New York, South Carolina, and Texas from 1985 to 2005. Data on protest occurrences in those states were gathered from online news reports, anti-testing organization websites, and electronic interviews from individuals associated with the anti-testing movement. Variables used in the analysis included each state's key educational accountability legislation, political affiliations of state political leaders, state political leaders' support of accountability issues, student ethnicity profiles, poverty indicators, dropout rates, and collective bargaining laws. I examined the relationship between those variables and protest development in terms of the political process model's three components: framing processes, mobilizing structures, and political opportunity. I concluded California and Massachusetts, with their strong networks of anti-testing organizations, showed more instances of protest than any other state. Slightly fewer protests occurred in New York. Texas showed few instances of anti-testing protests and there were no reports of protests in South Carolina. There was evidence of framing efforts from both proponents and opponents of high-stakes testing, with proponents' framing efforts tending to be more covert. I found that anti-testing protests were primarily initiated by middle-class and affluent groups of citizens, who demonstrated greater political access but whose major concerns differed by state. Evidence showed that although all five states have Republican governors, protests emerged more readily in the three states whose legislatures had a Democratic majority. I found that protest efforts were inhibited when protesters faced serious consequences as a result of their actions. In addition, state political leaders began to take part in the anti-testing protest movement once the state became subject to sanctions under the strict performance requirements imposed by No Child Left Behind. Overall, the political process model proved to be a highly efficient analytical tool in this context. digital.library.unt.edu/ark:/67531/metadc5501/
A Multi-Time Scale Learning Mechanism for Neuromimic Processing
Learning and representing and reasoning about temporal relations, particularly causal relations, is a deep problem in artificial intelligence (AI). Learning such representations in the real world is complicated by the fact that phenomena are subject to multiple time scale influences and may operate with a strange attractor dynamic. This dissertation proposes a new computational learning mechanism, the adaptrode, which, used in a neuromimic processing architecture may help to solve some of these problems. The adaptrode is shown to emulate the dynamics of real biological synapses and represents a significant departure from the classical weighted input scheme of conventional artificial neural networks. Indeed the adaptrode is shown, by analysis of the deep structure of real synapses, to have a strong structural correspondence with the latter in terms of multi-time scale biophysical processes. Simulations of an adaptrode-based neuron and a small network of neurons are shown to have the same learning capabilities as invertebrate animals in classical conditioning. Classical conditioning is considered a fundamental learning task in animals. Furthermore, it is subject to temporal ordering constraints that fulfill the criteria of causal relations in natural systems. It may offer clues to the learning of causal relations and mechanisms for causal reasoning. The adaptrode is shown to solve an advanced problem in classical conditioning that addresses the problem of real world dynamics. A network is able to learn multiple, contrary associations that separate in time domains, that is a long-term memory can co-exist with a short-term contrary memory without destroying the former. This solves the problem of how to deal with meaningful transients while maintaining long-term memories. Possible applications of adaptrode-based neural networks are explored and suggestions for future research are made. digital.library.unt.edu/ark:/67531/metadc278467/
A Multi-Variate Analysis of SMTP Paths and Relays to Restrict Spam and Phishing Attacks in Emails
Access: Use of this item is restricted to the UNT Community.
The classifier discussed in this thesis considers the path traversed by an email (instead of its content) and reputation of the relays, features inaccessible to spammers. Groups of spammers and individual behaviors of a spammer in a given domain were analyzed to yield association patterns, which were then used to identify similar spammers. Unsolicited and phishing emails were successfully isolated from legitimate emails, using analysis results. Spammers and phishers are also categorized into serial spammers/phishers, recent spammers/phishers, prospective spammers/phishers, and suspects. Legitimate emails and trusted domains are classified into socially close (family members, friends), socially distinct (strangers etc), and opt-outs (resolved false positives and false negatives). Overall this classifier resulted in far less false positives when compared to current filters like SpamAssassin, achieving a 98.65% precision, which is well comparable to the precisions achieved by SPF, DNSRBL blacklists. digital.library.unt.edu/ark:/67531/metadc5402/
Multi-year Operation Effect of Geothermal Heat Exchanger on Soil Temperature for Unt Zero Energy Lab
Ground source heat pump (GSHP) uses earth’s heat to heat or cool space. Absorbing heat from earth or rejecting heat to the earth, changes soil’s constant temperature over the multiple years. In this report we have studied about Soil temperature change over multiple years due to Ground loop heat exchanger (GLHE) for Zero Energy Research Laboratory (ZØE) which is located in Discovery Park, University of North Texas, Denton, TX. We did 2D thermal analysis GLHP at particular Depth. For simulation we have used ANSYS workbench for pre-processing and FLUENT ANYS as solver. TAC Vista is software that monitors and controls various systems in ZØE. It also monitors temperature of water inlet/outlet of GLHE. For Monitoring Ground temperatures at various depths we have thermocouples installed till 8ft from earth surface, these temperatures are measured using LabVIEW. From TAC Vista and LabVIEW Reading’s we have studied five parameters in this report using FLUENT ANSYS, they are; (1) Effect of Time on soil Temperature change over Multi-years, (2) Effect of Load on soil temperature change over Multi-years, (3) Effect of Depth on soil temperature change over Multi-years, (4) Effect of Doubling ΔT of inlet and outlet of GLHE on soil temperature change over multi-years and (5) Effect on soil temperature change for same ZØE Laboratory, if it’s in Miami, Florida. For studying effect of time on soil temperature change for multi-years, we have varied heating and cooling seasons. We have four cases they are Case A: GSHP always “ON” (1) 7 months cooling and 5 month cooling and (2) 257 days are cooling and 108 days heating. Case B: GSHP “OFF” for 2 months (1) 7 months cooling and 3 months heating and (2) 6 months cooling and 4 month heating. For Studying Effect of Load on soil temperature change over multi-years, we have considered maximum temperature difference between inlet and outlet for heating and cooling season for simulation. For studying effect of doubling ΔT of inlet and outlet of GLHE, we have doubled the temperature difference between inlet and outlet of GLHP. There will be soil temperature change over year at various depths. For studying Effect of Depth on soil temperature change for multi-years, we have consider 5 depths, they are 4ft, 6ft, 8ft, 110ft and 220ft. The Densities of soil are known from site survey report of ZØE GSHP manufacturers till depth of 13ft. For studying effect of soil temperature over multi-years for same ZØE in Miami, Florida, we have considered equivalent cooling and heating season from weather data for past one year and assuming same number of days of cooling and heating for next 20 years we have simulated for soil temperature change. digital.library.unt.edu/ark:/67531/metadc407847/
