Music Career Opportunities and Career Compatibility: Interviews with University Music Faculty Members and Professional Musicians
This study used a semistructured interview schedule to identify the music career opportunities available to students who graduate with an undergraduate music degree, and the skills, interests, work values, and personal characteristics that may determine a person's suitability for these music careers. Six university faculty members from each of the 11 NASM-accredited undergraduate music degree fields participated in the study (n = 66). Fourteen professional musicians who were recommended by these faculty members also participated in the study. Concerning the musical and non-musical skills that may determine a person's suitability for a music career, participants consistently noted the importance of performance skills in their respective fields. Participants also consistently cited people skills, and noted that most musicians interact with people on a daily basis, and use people skills to build social networks that may lead to employment. When asked about the interests that may lead someone to a music career, participants commonly cited the importance of good high school ensemble experiences in students' music career decisions. Concerning the rewarding aspects of music careers, many participants noted that they were more rewarded by the ability to support themselves doing what they loved, than by fame or wealth. Concerning the personal characteristics that may determine music career compatibility, participants noted that tenacity is essential to contend with intense competition, extended periods of unemployment, and other common struggles of professional musicians. When asked about music career opportunities in their respective fields, participants reported numerous music careers, some of which were excluded from previous music career inventories. In addition, participants noted that there may be careers for non-musicians in some music career fields. Participants also noted that some music careers may be listed in more than one music career field, creating potential confusion for music career advisors. Finally, participants noted transitions in many music careers that may change the professional expectations of these careers. digital.library.unt.edu/ark:/67531/metadc28398/
Music of the Spheres: Astronomy and Shamanism in the Music of Urmas Sisask
In 1619, Johannes Kepler published his magnum opus Harmonices mundi in which the astronomer derived distinct pitches and scales for each known planet in the solar system from calculations of various aspects of their orbital motions. This was the first theoretical realization of the ancient tradition of musica universalis (also called musica mundana), or music of the celestial bodies. It was not until the Estonian composer Urmas Sisask (b. 1960) began his compositional career by deriving his own “planetary scale,” however, that the theoretical musica universalis came into audible existence. Sisask’s work represents a distinctive musical voice among today’s choral composers, and although he is steadily gaining attention for his unique compositional style, only limited information exists about the specifics of his background, his interest in astronomy and shamanism, and the subsequent influence these interests have had on his choral music. At once traditional and modern, he bridges the gap between ancient Estonian folk song and the present. Through an application of exotic techniques including extreme repetition, ritualistically driving rhythms and sudden changes in timbre and texture; coupled with his own peculiarly crafted “planetary scale,” Urmas Sisask has created a completely unique body of work which is examined in this study by looking at representative works from his choral oeuvre including Gloria Patri…24 hymns for mixed choir, Magnificat, Ave Sol, and Benedictio. digital.library.unt.edu/ark:/67531/metadc149587/
Musical Arrangements and Questions of Genre: A Study of Liszt's Interpretive Approaches
Through his exceptional creative and performing abilities, Franz Liszt was able to transform compositions of many kinds into unified, intelligible, and pleasing arrangements for piano. Nineteenth-century definitions of "arrangement" and "Klavierauszug," which focus on the process of reworking a composition for a different medium, do not adequately describe Liszt's work in this area. His piano transcriptions of Schubert's songs, Berlioz's Symphonie fantastique and the symphonies of Beethoven are not note-for-note transcriptions; rather, they reinterpret the originals in recasting them as compositions for solo piano. Writing about Liszt's versions of Schubert's songs, a Viennese critic identified as "Carlo" heralded Liszt as the creator of a new genre and declared him to have made Schubert's songs the property of cultured pianists. Moreover, Liszt himself designated his work with Berlioz's Symphonie fantastique and the symphonies of Beethoven "Partitions de piano": literally, piano scores. As is well known, concepts of genre in general create problems for musicologists; musical arrangements add a new dimension of difficulty to the problem. Whereas Carl Dahlhaus identifies genre as a tool for interpreting composers' responses to the social dimension of music in the fabric of individual compositions, Jeffrey Kallberg perceives it as a "social phenomenon shared by composers and listeners alike." The latter concept provides a more suitable framework for discussing the genre of transcriptions, for their importance derives in large part from relationships between the original and the derivative works, both as constructed by Liszt and perceived by critics and audiences. During the nineteenth and early twentieth century's, Liszt's transcriptions of songs and symphonies were construed as both compositions for pianists and subsets of the originals. Consequently, these compositions should be studied for their own musical value as well as for the light that they shed on the original works. Liszt's transcriptions are derivative and at the same time created distinct genres. digital.library.unt.edu/ark:/67531/metadc28488/
Mutual Influences in Romantic Attachment, Religious Coping, and Marital Adjustment
This study examined associations among romantic attachment anxiety and avoidance, positive and negative religious coping, and marital adjustment in a community sample of 81 heterosexual couples. Both spouses completed the Experiences in Close Relationships Scale (ECR), a brief measure of religious coping (Brief RCOPE), the Dyadic Adjustment Scale (DAS), and a demographic questionnaire as part of a larger study. Multilevel modeling (MLM) for the actor-partner interdependence model (APIM) was used. Attachment avoidance was inversely related to positive religious coping. In contrast, attachment anxiety was directly related to negative religious coping. Positive religious coping buffered the relationship between attachment avoidance and marital adjustment. In contrast, attachment anxiety was detrimental to marital adjustment regardless of positive religious coping, and positive religious coping was related to higher marital adjustment only in the context of low attachment anxiety. Surprisingly, the spouse's attachment anxiety was inversely related to the respondent's marital adjustment only when the respondent reported low levels of negative religious coping, whereas in the context of high negative religious coping, the partner's attachment anxiety was related to higher marital adjustment. Results support using attachment theory to conceptualize religious coping and the consideration of both attachment and religious coping constructs in counseling. digital.library.unt.edu/ark:/67531/metadc283784/
My Crown Is in My Heart, Not on My Head: Heart Burial in England, France, and the Holy Roman Empire From Medieval Times to the Present
Access: Use of this item is restricted to the UNT Community.
Heart burial is a funerary practice that has been performed since the early medieval period. However, relatively little scholarship has been published on it in English. Heart burial began as a pragmatic way to preserve a body, but it became a meaningful tradition in Western Europe during the medieval and early modern periods. In an anthropological context, the ritual served the needs of elites and the societies they governed. Elites used heart burial not only to preserve their bodies, but to express devotion, stabilize the social order and advocate legitimacy, and even gain heaven. Heart burial assisted in the elite Christian, his or her family, and society pass through the liminal period of death. Over the centuries, heart burial evolved to remain relevant. The practice is extant to the present day, though the motivations behind it are very different from those of the medieval and early modern periods. digital.library.unt.edu/ark:/67531/metadc271809/
My Land, My Life
My Land, My Life is a documentary film about the woman, Jo Angela Lamb, who lives and works on Frying Pan Ranch in Texas Panhandle. the film explores the complexity of a ranch woman's experience that breaks the spell of the stereotyped image of American cowgirls. It also reflects on women ranchers’ relationship with their family members and their relationship with the land. digital.library.unt.edu/ark:/67531/metadc115188/
My Whine, Your Wine
Grapes hold the flavors of the lands where they grow, and when you make wine from them, those flavors of the land come through. Tasting wine from a place you've been can bring you back to that place with aromas and notes indicative of that place. A bottle of wine changes every day, and how it will taste depends on the moment you choose to release it from the glass walls. I have a vested interest in wine, because it is a living thing. I am compelled to make wine because its characteristics are like personality traits. Although some of those characteristics are harsh at times, I appreciate them all. Each trait plays an important role in the balance, the overall personality. Like my own personality flaws, wine's harsh tones can smooth over time. My relationship with wine is constantly evolving, with every new varietal, vintage, batch and blend. Believe me, after some of the jobs I had before my first day at Su Vino, I cherish every moment of my winemaking career. My Whine, Your Wine is the story of how it all started. digital.library.unt.edu/ark:/67531/metadc115041/
Mycielski-Regular Measures
Let μ be a Radon probability measure on M, the d-dimensional Real Euclidean space (where d is a positive integer), and f a measurable function. Let P be the space of sequences whose coordinates are elements in M. Then, for any point x in M, define a function ƒn on M and P that looks at the first n terms of an element of P and evaluates f at the first of those n terms that minimizes the distance to x in M. The measures for which such sequences converge in measure to f for almost every sequence are called Mycielski-regular. We show that the self-similar measure generated by a finite family of contracting similitudes and which up to a constant is the Hausdorff measure in its dimension on an invariant set C is Mycielski-regular. digital.library.unt.edu/ark:/67531/metadc84171/
The Myth of Emmetropia: Perception in Rhetorical Studies
This thesis sets up the problem of sight in a visual society, with the aim to answer how the visual makes itself known. The conversation starts on visuality, and where there are gaps in understanding. The first of two case studies examines the absence of sight, or blindness, both literal and figurative. Through a study of blind photographers and their work, this chapter examines the nature of perception, and how biological blindness may influence and inform our understanding of figurative blindness. The second case study examines what the improvement of damaged sight has to say about the rhetorical nature of images. This chapter examines various means of improving sight, using literal improvements to sight to understand figurative improvements in vision and perception. The fourth and final chapter seeks to sum up what has been discovered about the rhetorical nature of sight through the ends of the spectrum of sight. digital.library.unt.edu/ark:/67531/metadc149616/
The Myth of Strategic Superiority: Us Nuclear Weapons and Limited Conflicts, 1945-1954
The nuclear age provided U.S. soldiers and statesmen with unprecedented challenges. the U.S. military had to incorporate a weapon into strategic calculations without knowing whether the use of the weapon would be approved. Broad considerations of policy led President Dwight Eisenhower to formulate a policy that relied on nuclear weapons while fully realizing their destructive potential. Despite the belief that possession of nuclear weapons provided strategic superiority, the U.S. realized that such weapons were of little value. This realization did not stop planners from attempting to find ways to use nuclear weapons in Korea and Indochina. digital.library.unt.edu/ark:/67531/metadc115124/
Mythic Archaeologies: The Impact of Visual Culture on the Art and Identity of Four Hopi Artists
This qualitative critical ethnography examines how visual culture impacted the identity and art of four Hopi artists. Sources of data included a personal journal, artists’ interviews, group discussion, art work interpretations, and historical research of Hopi art, visual culture, and issues of native identity. In particular, my analysis focused on issues of power / knowledge relationships, identity construction, and the artist as co-constructor of culture through personal narratives. Implications for art education centered on the concept of storytelling through mythic archaeology situated in identities of past, present, and future. digital.library.unt.edu/ark:/67531/metadc103387/
Nanoparticles Engineered to Bind Serum Albumin: Microwave Assisted Synthesis, Characterization, and Functionalization of Fluorescently-Labeled, Acrylate-Based, Polymer Nanoparticles
The potential use of polymeric, functionalized nanoparticles (NPs) as drug delivery vectors was explored. Covalent conjugation of albumin to the surface of NPs via maleimide chemistry proved problematic. However, microwave assisted synthesis of NPs was not only time efficient, but enabled the exploration of size control by changing the following parameters: temperature, microwave power, reaction time, initiator concentration, and percentage of monomer used. About 1.5 g of fluorescently-labeled, carboxylic acid-functionalized NPs (100 nm diameter) were synthesized for a total cost of less than $1. Future work will address further functionalization of the NPs for the coupling of albumin (or other targeted proteins), and tests for in vivo biodistribution. digital.library.unt.edu/ark:/67531/metadc30466/
Nanoscale Materials Applications: Thermoelectrical, Biological, and Optical Applications with Nanomanipulation Technology
In a sub-wavelength scale, even approaching to the atomic scale, nanoscale physics shows various novel phenomena. Since it has been named, nanoscience and nanotechnology has been employed to explore and exploit this small scale world. For example, with various functionalized features, nanowire (NW) has been making its leading position in the researches of physics, chemistry, biology, and engineering as a miniaturized building block. Its individual characteristic shows superior and unique features compared with its bulk counterpart. As one part of these research efforts and progresses, and with a part of the fulfillment of degree study, novel methodologies and device structures in nanoscale were devised and developed to show the abilities of high performing thermoelectrical, biological, and optical applications. A single β-SiC NW was characterized for its thermoelectric properties (thermal conductivity, Seebeck coefficient, and figure of merit) to compare with its bulk counterpart. The combined structure of Ag NW and ND was made to exhibit its ability of clear imaging of a fluorescent cell. And a plasmonic nanosture of silver (Ag) nanodot array and a β-SiC NW was fabricated to show a high efficient light harvesting device that allows us to make a better efficient solar cell. Novel nanomanipulation techniques were developed and employed in order to fabricate all of these measurement platforms. Additionally, one of these methodological approaches was used to successfully isolate a few layer graphene. digital.library.unt.edu/ark:/67531/metadc84238/
Native American Elements in Piano Repertoire by the Indianist and Present-Day Native American Composers
My paper defines and analyzes the use of Native American elements in classical piano repertoire that has been composed based on Native American tribal melodies, rhythms, and motifs. First, a historical background and survey of scholarly transcriptions of many tribal melodies, in chapter 1, explains the interest generated in American indigenous music by music scholars and composers. Chapter 2 defines and illustrates prominent Native American musical elements. Chapter 3 outlines the timing of seven factors that led to the beginning of a truly American concert idiom, music based on its own indigenous folk material. Chapter 4 analyzes examples of Native American inspired piano repertoire by the "Indianist" composers between 1890-1920 and other composers known primarily as "mainstream" composers. Chapter 5 proves that the interest in Native American elements as compositional material did not die out with the end of the "Indianist" movement around 1920, but has enjoyed a new creative activity in the area called "Classical Native" by current day Native American composers. The findings are that the creative interest and source of inspiration for the earlier "Indianist" compositions was thought to have waned in the face of so many other American musical interests after 1920, but the tradition has recently taken a new direction with the success of many new Native American composers who have an intrinsic commitment to see it succeed as a category of classical repertoire. Native American musical elements have been misunderstood for many years due to differences in systems of notation and cultural barriers. The ethnographers and Indianist composers, though criticized for creating a paradox, in reality are the ones who saved the original tribal melodies and created the perpetual interest in Native American music as a thematic resource for classical music repertoire, in particular piano repertoire. digital.library.unt.edu/ark:/67531/metadc28485/
Natural Course of Adolescent Insomnia: Patterns and Consequences
Approximately 2-11% of adolescents report chronic insomnia. The study used an archival data set from ADDHealth that assessed adolescent health and health-related behaviors. Adolescents (N = 4102) provided data at baseline (Time 1) and at 1-year follow-up (Time 2). Participants were excluded if no ethnicity, gender, or insomnia data were given at Time 1 or 2. Females were more likely to report insomnia than males at Times 1 and 2. In addition, adolescents with remitted insomnia were significantly younger than adolescents without insomnia at Times 1 and 2. Analyses found a prevalence of 9.6%, a remittance of 6.2%, an incidence of 4.4%, and a chronicity of 2.9%. At Time 1 and 2, AWI were significantly more likely to have depression, suicidal behaviors, and behavioral problems in school than AWOI. At Time 2, incidence and chronic insomnia increased the risk of depression, suicidal behaviors and behavioral problems in school. Risk and protective factors analyses indicated psychological counseling was associated with both remitted and chronic insomnia and depression was associated with incidence insomnia. digital.library.unt.edu/ark:/67531/metadc30506/

Networking of North and West Texas Superintendents
This study examined the professional networking of North and West Texas public school superintendents. It looked at how these superintendents professionally network, use professional organizations in networking, and how they extend opportunities beyond the organizations to gain knowledge and information about their demanding and stressful responsibilities. Lastly, it looked at superintendents in the field on whom others rely for knowledge and understanding. Surveys were mailed out to 443 North and West Texas public schools. Only the superintendents from those districts were asked to complete the survey. This limitation was desired to restrict the population to only the superintendents of schools, thus focusing the study on the professional networking of only superintendents. Three hundred sixty (360) superintendents responded to the survey, a return rate of 81.3%. This research concluded that superintendents professionally network by communicating through monthly meetings, organizational conferences or meetings, or email. Their networks are facilitated through communication, contacts, location, longevity, and organizational associations. These organizations provide the superintendent's primary network contact. The number of contacts in a network is usually a small group of 5 to 9 professionals who are known from longevity in the profession, prior educational positions, similar district size, being located in or near a city, and other geographic neighbors. digital.library.unt.edu/ark:/67531/metadc28391/
Neuropsychological Functioning in Active Duty Soldiers with Physical and/or Psychological Trauma
This quasi-experimental study investigates neuropsychological functioning differences between 63 active duty soldiers who were placed into three groups (MTBI, PTSD, control) to provide better information for differentiating PTSD and MTBI. The ANAM and MicroCog were utilized to measure psychomotor speed, memory, and attention. Participants with PTSD performed worse on most measures of psychomotor speed and attention, and endorsed more symptoms of depression and anxiety when compared to MTBI and control participants. Further, attention appears to be the best cognitive domain for differentiating PTSD from MTBI, whereas memory variables did not differentiate these groups. Clinical and research implications of these findings are discussed. digital.library.unt.edu/ark:/67531/metadc33180/
Never Odd Or Even: Using Temporal Structures In Composing Music For Dance
This study engages the collaboration of dance and music, focusing primarily on experiences in the production of a large scale collaborative concert entitled Never Odd or Even. Famous historical collaborations offer archetypal collaborative models, the more unconventional of which are applied to the pieces of the concert. Issues and observations regarding cross-influence, project evolution, and application of the collaborative models are engaged to determine effective means of collaboration given different circumstances. The key focus of the study, the temporal relationship between music and dance, is explored in great detail to determine three models for relating time between music and dance. These temporal relationship models are applied to the pieces and evaluated on effectiveness and potential strengths when applied to dance. digital.library.unt.edu/ark:/67531/metadc115047/
A New Approach for Transition Metal Free Magnetic Sic: Defect Induced Magnetism After Self-ion Implantation
SiC has become an attractive wide bandgap semiconductor due to its unique physical and electronic properties and is widely used in high temperature, high frequency, high power and radiation resistant applications. SiC has been used as an alternative to Si in harsh environments such as in the oil industry, nuclear power systems, aeronautical, and space applications. SiC is also known for its polytypism and among them 3C-SiC, 4H-SiC and 6H-SiC are the most common polytypes used for research purposes. Among these polytypes 4H-SiC is gaining importance due to its easy commercial availability with a large bandgap of 3.26 eV at room temperature. Controlled creation of defects in materials is an approach to modify the electronic properties in a way that new functionality may result. SiC is a promising candidate for defect-induced magnetism on which spintronic devices could be developed. The defects considered are of room temperature stable vacancy types, eliminating the need for magnetic impurities, which easily diffuse at room temperature. Impurity free vacancy type defects can be created by implanting the host atoms of silicon or carbon. The implantation fluence determines the defect density, which is a critical parameter for defect induced magnetism. Therefore, we have studied the influence of low fluence low energy silicon and carbon implantation on the creation of defects in n-type 4H-SiC. The characterization of the defects in these implanted samples was performed using the techniques, RBS-channeling and Raman spectroscopy. We have also utilized these characterization techniques to analyze defects created in much deeper layers of the SiC due to implantation of high energy nitrogen ions. The experimentally determined depths of the Si damage peaks due to low energy (60 keV) Si and C ions with low fluences (< 1015 cm-2) are consistent with the SRIM-2011 simulations. From RBS-C Si sub-lattice measurements for different fluences (1.1×1014 cm-2 to 3.2×1014 cm-2) of Si implantation in 4H-SiC, the Si vacancy density is estimated to range from 1.29×1022 cm-3 to 4.57×1022 cm-2, corresponding to average vacancy distances of 4.26 Å to 2.79 Å at the damage peak (50±5 nm). Similarly, for C implanted fluences (1.85×1014 cm-2 to 1×1015 cm-2), the Si vacancy density varies from 1.37×1022 cm-3 to 4.22×1022 cm-3 with the average vacancy distances from 4.17 Å to 2.87 Å at the damage peak (110±10 nm). From the Raman spectroscopy, the implantation-induced lattice disorders calculated along the c-axis (LO mode) and perpendicular to c-axis (TO mode) in 4H-SiC are found to be similar. Furthermore, the results obtained from SQUID measurements in C implanted n-type 4H-SiC sample with fluences ranging from 1×1012 to 1.7×1016 ions/cm2 have been discussed. The implanted samples showed diamagnetism similar to the unimplanted sample. To date, to our best of knowledge, no experimental work has been reported on investigating defect induced magnetism for self-ion implantation in n-type 4H-SiC. These first reports of experimental results can provide useful information in future studies for a better understanding of self-ion implantation in SiC-based DMS. digital.library.unt.edu/ark:/67531/metadc271849/
A New Chromophoric Organic Molecule Toward Improved Molecular Optoelectronic Devices
Access: Use of this item is restricted to the UNT Community.
The characterization of 2,3,6,7,10,11-hexabromotriphenylene, Br6TP, is presented toward its potential use as an n-type organic semiconductor and metal-free room temperature phosphor. The crystal structure shows both anisotropic two-dimensional BrBr interactions and inter-layer ?-stacking interactions. Photophysical characteristics were evaluated using solid-state photoluminescence and diffuse reflectance spectroscopies, revealing significantly red-shifted excitations in the visible region for the yellow solid material (compared to ultraviolet absorption bands for the colorless dilute solutions). Correlation of spectral, electrochemical, and computational data suggest the presence of an n-type semiconducting behavior due to the electron-poor aromatic ring. The material shows excellent thermal stability as demonstrated by thermogravimetric analysis and infrared spectra of a thin film deposited by thermal evaporation. The potential for Br6TP and its analogues toward use in several types of photonic and electronic devices is discussed. digital.library.unt.edu/ark:/67531/metadc177207/
A New Literary Realism: Artistic Renderings of Ethnicity, Identity, and Sexuality in the Narratives of Philip Roth
Access: Use of this item is restricted to the UNT Community.
This dissertation explores Goodbye, Columbus and Five Short Stories (1959), the Ghost Writer (1979), the Counterlife (1986), the Facts (1988), Operation Shylock (1993), Sabbath's Theater (1995),and the Human Stain (2000), arguing that Roth relishes the telling of the story and the search for self within that telling. with attention to narrative technique and its relation to issues surrounding reality and identity, Roth's narratives stress unreliability, causing Roth to create characters searching for a more complex interpretation of self. Chapter I examines Roth’s negotiation of dual identities as Neil Klugman in Goodbye, Columbus feels alienated and displaced from Christianized America. the search for identity and the merging of American Christianity and Judaism remain a focus in Chapter II, which explores the implications of how, in the Ghost Writer, a young Nathan Zuckerman visits his mentor E.I. Lonoff to find him living in what he believes to be a non-Jewish environment—the American wilderness. Chapter II also examines the difficulties of cultural assimilation in "Eli, the Fanatic," in which Eli must shed outward appearances of Judaism to fit into the mostly Protestant community of Woodenton. Relative to the negotiation of multiple identities, Chapter III considers Sabbath’s attempt, in Sabbath’s Theater, to reconcile his spiritual and physical self when seeking to avoid his inevitable death. Exploring a further dimension of the search for self, Chapter IV traces the legacy of stereotyped notions of identity, considering ways in which Roth subverts stereotypes in the Human Stain. the search for identity and its particular truths remains a focus of Chapter V, which explores Roth's creation of an unstable reality through the Counterlife, the Facts, Operation Shylock, and the Human Stain, suggesting that the literary imagination matters more than truth in fiction. in its attention to Roth's focus on identity, race, and narrative technique, this dissertation contributes to the evolution of criticism addressing the social significance of the major works of Philip Roth. digital.library.unt.edu/ark:/67531/metadc115092/
Newspaper Ownership Structure and the Quality of Local Political News Coverage
This research sought to ascertain how newspaper ownership structures influence the quality of local political news coverage. More specifically, do independently owned newspapers tend to produce larger quantities of quality local political reporting than do corporately owned and publicly traded newspapers? In the thesis, I develop an understanding of "quality" news coverage as being coverage that is thematic, or providing interpretive analysis and supplying contextual information. Additionally, I tackle the question of quality news coverage from three angles: whether or not independently owned newspapers provide more quality local political news stories per edition than corporately owned papers; whether or not the percentage of quality local political news stories of total political news stories within an edition is higher for independently owned or corporately owned newspapers; and whether or not the percentage of total political news stories of total news stories is higher for independently owned or corporately owned newspapers. digital.library.unt.edu/ark:/67531/metadc115055/
The “Nigger Trinity”: Engaging the Discourse in Post Civil Rights/Post 1960s America
Access: Use of this item is restricted to the UNT Community.
The cultural and popular media landscape of the United States of America changed after the Civil-Rights movement of the 1960s. The word “Nigger” was changed during that same period of American history. There are several authors and a comic that helped change this word during the 1960s. The post Civil-Rights American has a different experience and understanding with this word than those born before 1970. This work triangulates the current cultural location of the word “Nigger,” “nigga,” and “the n-word” using linguistics, law, and two media case studies. The “Nigger” trinity is a model that adds value to the discourse that surrounds this one word in post civil-rights/post 1960s America. digital.library.unt.edu/ark:/67531/metadc103290/
Nihilism and the Formulation of a Philosophy of Art
Nihilism is often associated with feelings of despair, hopelessness and meaningless. It is certainly true that once the implications of this philosophy become apparent that these feelings are valid. However, this reaction is merely the first stage of dealing with nihilism and stopping here fails to examine the various types of nihilism that deal specifically with knowledge, ethics, metaphysics, truth, and art. Nihilism at its base is a philosophy that recognizes the history of human thought and what it means to be and to think. My focus is the way in which a completed nihilism is in fact an emancipatory act and the implications it has for art and the artist in the 21st century. digital.library.unt.edu/ark:/67531/metadc67991/
Ninth-grade Students’ Negotiation Of Aesthetic, Efferent, And Critical Stances In Response To A Novel Set In Afghanistan
This qualitative, action research study was guided by two primary research questions. First, how do students negotiate aesthetic, efferent, and critical stances when reading a novel set in Afghanistan? Second, how do aesthetic and efferent stances contribute to or hinder the adoption of a critical stance? A large body of research exists that examines student responses to literature, and much of that research is based on the transactional theory of reading. However, it remains unclear how critical literacy fits into this theory. This study describes how one group of high school students’ aesthetic and efferent responses to a novel set in Afghanistan supported their development of critical stances. Six students enrolled in a ninth-grade English course participated in this study. Data were collected for 13 weeks. Data included two individual interviews with each student, student writing assignments in the form of 6 assigned journal entries and 7 assigned essays, transcriptions of 12 class discussions, field notes, lesson plans, a teacher researcher journal, and research memos. Data were analyzed using the constant comparative method. Three major findings emerged from this study. First, class discussions provided a context for students to adopt stances that were not evident in their individual written responses to the novel, which were completed prior to the discussions. Second, the discussions provided scaffolding that helped several of the students adopt world-efferent and critical stances. Third, both the aesthetic and the efferent stances contributed to students’ adoption of critical stances. digital.library.unt.edu/ark:/67531/metadc103398/
NNS Use of Adverbs in Academic Writing
Recent studies have begun to redefine the idea of accuracy in second language acquisition to include not only grammatical correctness, but also native-like selection. This is an exploratory study aimed at identifying areas of nonnative-like selection of adverbs, such as sentence position, semantic category preferences, frequency of use and breadth of word choice. Using corpus-linguistic methods it compares the writing of nonnative English speakers at an intermediate and advanced level to both American college students’ writing and published academic writing. It also conducts in-depth case studies of three of the most commonly used adverbs. It finds that while advanced students are grammatically accurate, there are still several ways in which their use of adverbs differs from that of native speakers. digital.library.unt.edu/ark:/67531/metadc84213/
No Greater Error: Negotiated Agreements and Their Effects on the Conclusion of Interstate War
Negotiated settlements, formal treaties to unilateral cease-fires, are often accepted to be the preferable method to end war. When negotiated agreements are used in the normal business of international politics they can be potentially helpful devices; however, when they are relied upon for a nation's security or war prevention and conclusion they can prove disastrous. It is the presence of force variables, and not the formality of an agreement which effectively concludes a war. I recategorize success of an agreement to not only mean failure of a return to war, but also whether the tenets of an agreement are actually followed. I utilize a modified version of Fortna's conflict dataset and run three separate logit analyses to test the effectiveness of settlements in a medium n quantitative analysis. If politicians and policy makers realize that it is not treaties that establish peace but the costs of war and military might then perhaps the world will be a more peaceful place. digital.library.unt.edu/ark:/67531/metadc177217/
No-thought Shopping: Understanding and Controlling Nonconscious Processing in Marketing
This dissertation explores how nonconscious thought processing might be affected and activated in ways that influence consumer decision making. To activate nonconscious thought processes, this dissertation relies on priming—the unobtrusive activation of mental representations by stimuli in a social context, which occurs without participants' conscious awareness. Three dimensions of consumer decision making are investigated: purchase intention, product evaluation and arousal. The dissertation is based on the auto-motive model of nonconscious goal pursuit and somatic marker hypothesis. The dissertation is driven by three experiments, which respectively explore crucial areas in priming effects and addresses the following research question: can primes be shaped or controlled by marketers? Specifically, the dissertation examines whether shopping behavior can be primed. Second, the dissertation also examines how facial primes displaying basic emotions (happiness, anger, contempt, disgust, fear, sadness, and surprise) can prime emotion and arousal. Finally the dissertation examines the effect of the interaction of the buying prime with the primes of faces displaying basic emotions on the dependent variables of purchase intention, product evaluation, emotion, and arousal. Results from three experimental studies show that shopping behavior can be primed, and primed participants will exhibit higher product evaluation than those exposed to a control prime. Second while exposing participants to primes of faces displaying emotions did not elicit those emotions, the priming with faces did reveal a marginal activation of arousal in the participants. Third priming with faces was not found to interact with primed buying behavior such that the interaction would affect the level of arousal. The results indicate that Bargh's auto-motive model of nonconscious goal pursuit can be applied to marketing. Thus priming shopping behavior can affect product evaluation though the effect of this prime appears to be too weak to be applied in the field. Priming with faces was found not to interact with primed shopping behavior and thus affect product evaluation. The impact of the findings on marketing practitioners suggests that more laboratory investigation is necessary. Further laboratory investigation should be used to raise the effect level of the prime and to find ways to shape and control nonconscious goal pursuit prior to attempting to bring priming into the field. digital.library.unt.edu/ark:/67531/metadc271812/

This dissertation is composed of two parts. Part I discusses the evolution of meditative poetry as a genre, with a particular emphasis on the influence of women poets and feminist critical theory. Part II is a collection of poems. Although several popular and critically-acclaimed poets working today write meditative poems, meditative poetry as a genre has not been systematically examined since M.H. Abrams’s essay on the meditative mode in Romantic poetry, “Structure and Style in the Greater Romantic Lyric.” Because one of the driving forces of meditative poetry is a longing for, or recognition of, a state of perception that lies between individual being and some form of universal ordering principle, meditative poetry might seem to be antithetical to a postmodern world that is fragmentary, contingent, and performative; indeed, earlier definitions of meditative poetry, tied to historical and cultural understandings of the individual and the Universal, no longer reflect “how we know” but only “how we knew.” However, this essay argues that there is a contemporary meditative structure that allows for a continued relationship between the individual and the Universal without resorting to the essentialism implicit in the genre as traditionally described. This new structure owes much to feminist theory, in particular écriture féminine, which models a method for recovery of self in language that would seek to efface it. In order to expose the boundaries of the contemporary meditative mode, and to outline its relationship to écriture féminine, this essay analyzes meditative poems from four contemporary poets: Kay Ryan, Jorie Graham, Linda Gregerson, and Linda Bierds, and contrasts contemporary variations on the genre with earlier traditions, identifying an evolved form that better reflects a postmodern rhetoric. digital.library.unt.edu/ark:/67531/metadc103295/

Nominal Shear Strength and Seismic Detailing of Cold-formed Steel Shear Walls using Steel Sheet Sheathing
In this research, monotonic and cyclic tests on cold-formed steel shear walls sheathed with steel sheets on one side were conducted to (1) verify the published nominal shear strength for 18-mil and 27-mil steel sheets; and (2) investigate the behavior of 6-ft. wide shear walls with multiple steel sheets. In objective 1: this research confirms the discrepancy existed in the published nominal strength of 27-mil sheets discovered by the previous project and verified the published nominal strength of 18 mil sheet for the wind design in AISI S213. The project also finds disagreement on the nominal strength of 18-mil sheets for seismic design, which is 29.0% higher than the published values. The research investigated 6-ft. wide shear wall with four framing and sheathing configurations. Configuration C, which used detailing, could provide the highest shear strength, compared to Configurations A and B. Meanwhile, the shear strength and stiffness of 2-ft. wide and 4-ft. wide wall can be improved by using the seismic detailing. digital.library.unt.edu/ark:/67531/metadc30444/
Nominal Shear Strength of Cold-formed Steel Shear Walls Using Osb Sheathing
In the cold-formed steel construction, the oriented strand board is a common material for shear wall sheathing. an OSB is made by using wood chips as raw materials that undergo high temperature pressing to create a multi-larger structure material. Due to the OSB having a high strength in shear, it is an important material used in the construction field. the thesis is trying to verify published nominal shear strength in AISI-213-07 in the first part. This objective has two parts: the first part is to verify nominal shear strength (Rn) for wind and other in-plane loads for shear wall. the second part is to verify nominal shear strength (Rn) for seismic and other in-plane loads for shear wall. Secondly, the thesis verifies the design deflection equation for nominal shear strength of CFS shear walls with OSB sheathing. the test specimens were divided into eight groups which trying to verify the design deflection equation that was published in AISI-213-07 standard. digital.library.unt.edu/ark:/67531/metadc115111/
A Non-equilibrium Approach to Scale Free Networks
Many processes and systems in nature and society can be characterized as large numbers of discrete elements that are (usually non-uniformly) interrelated. These networks were long thought to be random, but in the late 1990s, Barabási and Albert found that an underlying structure did in fact exist in many natural and technological networks that are now referred to as scale free. Since then, researchers have gained a much deeper understanding of this particular form of complexity, largely by combining graph theory, statistical physics, and advances in computing technology. This dissertation focuses on out-of-equilibrium dynamic processes as they unfold on these complex networks. Diffusion in networks of non-interacting nodes is shown to be temporally complex, while equilibrium is represented by a stable state with Poissonian fluctuations. Scale free networks achieve equilibrium very quickly compared to regular networks, and the most efficient are those with the lowest inverse power law exponent. Temporally complex diffusion also occurs in networks with interacting nodes under a cooperative decision-making model. At a critical value of the cooperation parameter, the most efficient scale free network achieves consensus almost as quickly as the equivalent all-to-all network. This finding suggests that the ubiquity of scale free networks in nature is due to Zipf's principle of least effort. It also suggests that an efficient scale free network structure may be optimal for real networks that require high connectivity but are hampered by high link costs. digital.library.unt.edu/ark:/67531/metadc149609/
Non-Linear and Multi-Linear Time in Beethoven's Opus 127: An Analytical Study of the "Krakow" Sketch Materials
Beethoven's complex manipulation of formal structures, especially his tendency to build important connections and transformative continuities between non-adjacent sections of musical works, may be seen to function as an attempt to control and sometimes to distort the listener's perception of both the narrative process of musical directionality, as well as the subjective interpretation of time itself. Temporal distortion often lies at the heart of Beethoven's complex contrapuntal language, demonstrated equally through the composer's often enigmatic disruption of phrase-periodic gestures, as well as by occasional instances of overtly incongruous temporal shifts. The "Krakow" collection of compositional sketches for Beethoven's String Quartet in E-Flat, Op. 127, provides a number of instances of "non-linear" or "multi-linear" musical continuity. The term "Krakow" sketches, when referenced in this dissertation, specifically designates the group of Beethoven manuscripts possessed by the Biblioteka Jagiello&#324;ska in Krakow, Poland, but which formerly were held by the Royal Library in Berlin. Structural voice-leading analyses are provided for selected portions of the "Krakow" collection; these analyses are then compared to voice-leading graphs and analytical reductions of the corresponding material from Beethoven's published versions of the same musical passages. In some cases the sketches supply almost complete texts, for which critical transcriptions are included as extended examples within the dissertation. The primary analytical technique applied to both compositional sketches as well as to complete musical texts derives from Heinrich Schenker's theory of structural voice-leading and graphical reduction. An important method of critical assessment, from which a number of theoretical arguments are developed, is the contention that Beethoven's contrapuntal language, at least in regard to the op. 127 String Quartet, relies heavily upon a temporal distortion of both form and phrase-periodic gestures, requiring the listener to actively re-construct the continuity of Beethoven's subjective formal archetypes. digital.library.unt.edu/ark:/67531/metadc31540/
Nonparametric Estimation of Receiver Operating Characteristic Surfaces Via Bernstein Polynomials
Access: Use of this item is restricted to the UNT Community.
Receiver operating characteristic (ROC) analysis is one of the most widely used methods in evaluating the accuracy of a classification method. It is used in many areas of decision making such as radiology, cardiology, machine learning as well as many other areas of medical sciences. The dissertation proposes a novel nonparametric estimation method of the ROC surface for the three-class classification problem via Bernstein polynomials. The proposed ROC surface estimator is shown to be uniformly consistent for estimating the true ROC surface. In addition, it is shown that the map from which the proposed estimator is constructed is Hadamard differentiable. The proposed ROC surface estimator is also demonstrated to lead to the explicit expression for the estimated volume under the ROC surface . Moreover, the exact mean squared error of the volume estimator is derived and some related results for the mean integrated squared error are also obtained. To assess the performance and accuracy of the proposed ROC and volume estimators, Monte-Carlo simulations are conducted. Finally, the method is applied to the analysis of two real data sets. digital.library.unt.edu/ark:/67531/metadc177212/
Novel Role of Trypsin in Zebrafish
Access: Use of this item is restricted to the UNT Community.
It has been shown previously in our laboratory that zebrafish produce trypsin from their gills when they are under stress, and this trypsin is involved in thrombocyte activation via PAR2 during gill bleeding. In this study, I investigated another role of the trypsin that is secreted from zebrafish. This investigation has demonstrated a novel role of trypsin in zebrafish. Not only did this investigation demonstrate the role of trypsin in zebrafish behavior, but also it showed that PAR2 might be the receptor that is involved in trypsin-mediated behavioral response. In addition, we have shown that Gq and ERK inhibitors are able to block the trypsin pathway and prevent the escaping behavior. Finally, the results of this investigation suggest that the cells that respond to trypsin are surface cells, which have an appearance similar to that of neuromast cells. digital.library.unt.edu/ark:/67531/metadc271771/
Novice Generalist and Content teachers’ Perceptions of Contextual Factors Affecting Personal Teaching Efficacy
New teachers begin the school year with optimism and enthusiasm, but their excitement quickly wanes as they encounter the realities of the everyday life of a teacher. When they do not experience the successes they predicted, many begin to doubt their capabilities, which results in a lowered sense of teaching efficacy. This descriptive study was designed to identify the contextual factors novice teachers perceive as influences on personal teaching efficacy and to examine the relationships between the factors. Two groups of novice teachers who were concurrently enrolled in a post-baccalaureate accelerated educator preparation program and working as first-year teachers were the participants in the study. Data were gathered for the study through focus group activities, twice weekly journal entries completed during the teaching year, and a culminating “lessons learned” paper written during the last month of the first year of teaching. Each of the two focus groups identified nine contextual factors they perceived to affect personal teaching efficacy. Six factors were identified by both groups: parental involvement, support from administrators and colleagues, classroom discipline, testing results, teaching strategies and outcomes, and relationships with administrators and colleagues. The groups, however, perceived the relationships between the contextual factors differently. The generalists perceived recursive relationships between the factors, while the content group perceived a linear relationship. digital.library.unt.edu/ark:/67531/metadc84221/
Novice Teachers' Stories Represented As a Graphic Narrative
The issue of alternative certification teacher training has greatly affected art education over three decades. As a result of training through alternative certification, many art educators enter the profession unprepared and unable to cope with the realities of teaching. This study attempts to understand and represent the experiences and struggles of four alternatively certified art teachers, including myself. By reading these stories, others within the education community can empathize with and provide support for struggling novice teachers. This creative thesis uses a graphic novel format to represent participants' stories. By combining text and imagery, the graphic novel format provides different meanings, interpretations, and insights into the teachers' lives. This medium offered a unique and rich perspective on the stories of what it is like being an alternatively certified art teacher. digital.library.unt.edu/ark:/67531/metadc271802/
Le Nuove Musiche: Giovanni Battista Bovicelli?
This thesis is a comparative study on the late 16th century manuals of ornamentation by Girolamo Dalla Casa, Giovanni Bassano, Riccardo Rognoni, and Giovanni Battista Bovicelli. The study demonstrates that the latest Renaissance manual should be given more credit for the innovative ornamentation style that was to come in the Early Baroque era. Bovicelli's use of sequence, dissonances, and less moving notes for more rhythmic varieties are features most often associated in the style of the Baroque. Unfortunately, the topic of ornamentation in the late Renaissance is most commonly discussed as a group of different entities writing in the same style. The research for this paper is intended to separate the manuals of the late Renaissance, focusing on the separate styles that led to the work of Giovanni Battista Bovicelli. digital.library.unt.edu/ark:/67531/metadc30458/
An Observation of Early Parent-Infant Social Interactions in Relation to the Emergence of Joint Attention in the Natural Environment
Early interactions between parents and infants are thought to be critical of later development. In particular joint attention has been an area of research and investigations. This study sought to measure joint attention behaviors in infants from 5 to 33 weeks of age under naturalistic conditions: in the home with the mother as the interaction partner given no instructions. Videotapes of the infant-parent interactions were observed and data were collected on behaviors related to joint attention. Given observations occur at younger ages than other studies considered, engagement data results indicate increasing trends for 3 of the 5 infants observed while the direction of infant gaze results indicate patterns consistent with descriptions currently in the literature. Parent behavior data indicate high levels of support in engaging infant attention. Furthering an understanding of joint attention by observing at earlier ages in infant development may be useful in informing teaching programs for infants who have not developed joint attention skills. digital.library.unt.edu/ark:/67531/metadc30428/
Ocean of Forms: for Soprano and Computer
Ocean of Forms is a cycle of five songs for solo soprano voice and electronic/computer music accompaniment on poems by noted Bengali poet, musician, philosopher, and author Rabindranath Tagore. This work approaches the song cycle as a vehicle for expressing and highlighting the poet's words. Word and syllabic stress, text painting, melodic development, and formal structure all function in relation to the text and its meaning. the replacement of the traditional piano accompaniment with electronic accompaniment provides further possibilities for new timbral structures and transformations, expressive microtonal intonation, algorithmic and aleatoric formal structures, acousmatic and spatialized sound, and a broad sonic palette. This work strives to provide a more fully developed expression of the text as afforded by these expanded musical means. the critical essay primarily explores the interaction between text and music in the work. the first chapter explores the historical precedents for the genre of the song cycle and other texted music as well as specific influences on the work. the following chapters explore the connections between the text and the vocal line and electronic/computer music, respectively. the final chapter deals with the formal structure of the work, especially the justly-tuned harmonic scheme and its relation to the text. digital.library.unt.edu/ark:/67531/metadc115141/
Oh G-d, A Borderline: Clinical Diagnostics As Fundamental Attribution Error
Researchers raise concerns that the diagnostic approach can create stigma and lead to clinical inferences that focus on dispositional characteristics at the expense of situational variables. From social cognitive theory to strict behavioral approaches there is broad agreement that situation is at least as important as disposition. The present study examined the clinical inferences of graduate student clinicians randomly presented a diagnosis (borderline PD) or no diagnosis and either randomly given context information or no context information before watching a videotaped clinical interaction of a fabricated client. Responses to a questionnaire assessing dispositional or situational attributions about the client’s behavior indicated a diagnosis of borderline personality disorder did not significantly increase dispositional attributions and did not significantly moderate the importance of contextual factors. A notable difference between the attributions made by psychodynamic and third wave behavioral respondents was observed. Conceptual and experimental limitations as well as future directions are discussed. digital.library.unt.edu/ark:/67531/metadc103389/
Older Workers: Disability And Employment
The purpose of this study was to explore the demographic variables, typical vocational services, and competitive employment rates of older workers, ages 40 - 69 years of age, with disabilities using the RSA-911 database. The results describe the types of services received and the competitive employment outcomes for state and federal vocational rehabilitation consumers receiving services in 2009. Furthermore the sample of older workers (N = 1,152) was equally stratified into three age groups. Older workers, aged 60 to 69, had higher levels of education, received more types of vocational services, and were competitively employed at a much higher rate than those in the other age groups. The methods, discussion, study limitations, and recommendations for future research are presented. digital.library.unt.edu/ark:/67531/metadc103355/
On Steinhaus Sets, Orbit Trees and Universal Properties of Various Subgroups in the Permutation Group of Natural Numbers
In the first chapter, we define Steinhaus set as a set that meets every isometric copy of another set at exactly one point. We show that there is no Steinhaus set for any four-point subset in a plane.In the second chapter, we define the orbit tree of a permutation group of natural numbers, and further introduce compressed orbit trees. We show that any rooted finite tree can be realized as a compressed orbit tree of some permutation group. In the third chapter, we investigate certain classes of closed permutation groups of natural numbers with respect to their universal and surjectively universal groups. We characterize two-sided invariant groups, and prove that there is no universal group for countable groups, nor universal group for two-sided invariant groups in permutation groups of natural numbers. digital.library.unt.edu/ark:/67531/metadc149691/
On Their Own: How Thirty-One Tribal Colleges Address Five Educational Concepts
This qualitative research, specifically a content analysis of 31 tribal colleges' mission statements and curricula, examined how the colleges' curricula aligned with the five educational concepts suggested in the colleges' mission statements. Cajete's (1994) seven foundations to indigenous thinking proved to be a major theoretical framework which provided a worldview for tribal learning. The study concluded that whereas the five educational concepts aligned between mission statements and curricula, the curricula emphasized culture, tribal community, and academic success at a greater level than mission statements indicated. Further, tribal colleges' curricula did not emphasize economic concepts as the mission statements indicated. A particular finding suggests that tribal colleges' are investing in environmental studies programs, thus increasing their intellectual capacity to protect their environmental interests while promoting indigenous thinking and community learning across all academic disciplines. Considerable implications include that an increase of American Indian environmental studies graduates may have a positive impact on environmental justice matters as well as the ability to promote new agricultural technologies. Additional implications include how mainstream universities will adapt to an increase of native students studying the sciences rather than liberal arts. digital.library.unt.edu/ark:/67531/metadc28466/
Online Course Design Elements to Better Meet the Academic Needs of Students with Dyslexia in Higher Education
This study sought to determine if an online course designed and delivered in Second Life can meet the needs of higher education students with dyslexia. the course design incorporated strategies from Gagne’ and Briggs’ principles of instruction, Gagnon and Collay’s constructivist learning design, Powell’s key learning needs of dyslexics, and elements of universal design. Specific design elements are discussed including screen captures from the design. the study employed a mixed methods approach incorporating an online survey, recorded observation session, and two follow up interviews. the observation session and interviews were only completed by the sample population of eight participants, which included three participants with dyslexia and five participants without dyslexia. the sample population was selected using purposeful sampling techniques to ensure the widest representation of the population with a small sample. Extensive excerpts of the sample participants’ interview responses are presented and discussed, including participants’ suggestions for improving the course design. Key findings from all three data sources are discussed. Finally, implications for instructional design and special education and suggestions for further research are presented. digital.library.unt.edu/ark:/67531/metadc115072/
Online Lecture As an Alternative Method of Instruction in College Classrooms: Measuring the Effects of Alternating In-class with Online Lectures in Two Sections of an Undergraduate Introduction to Behavior Analysis Course
Online instruction is becoming increasingly common at universities; however, there is little single subject research concerning the effectiveness of the online lecture format. We investigated whether online lecture could replace in-class lecture in two sections of an undergraduate Introduction to Behavior Analysis course without detrimentally affecting student learning. Using an adapted alternating treatments design, online and in-class lecture formats were counterbalanced across the two course sections. Experimenters collected data on lecture attendance/access, percent correct on the weekly quiz, and student report on lecture format preference. The data show that, within the context of this class, students performed equally in the weekly quiz regardless of lecture format; further, that this is consistent when looking at individual student data and mean data. However, although students stated a preference for online lecture in the questionnaire, a greater percentage of students attended in-class lecture than accessed online lecture. digital.library.unt.edu/ark:/67531/metadc271907/
Opera at the Threshold of a Revolution: Francis Poulenc’s Dialogues des Carmélites (1953-1956)
Francis Poulenc’s three-act opera Dialogues des Carmélites (1953-1956) depicts the struggles of the novice nun Blanche de la Force during the Reign of Terror of the French Revolution. The use of Latin liturgical music at critical points in the opera conveys the ritualistic nature of Catholic worship. The spiritual message of mystical substitution, along with the closely related notion of vicarious suffering, imbue the opera with a spirituality that offers a sharp contrast to earlier operatic settings of Catholic texts, particularly during the age of grand opera. Marian devotion also plays an important role in the opera. The final tableau of the opera stages the execution of Blanche and her sisters, complete with the sound of a guillotine, with the nuns singing the Salve Regina as they proceed to the scaffold. The multivalence of the final tableau highlights the importance of voice and its absence. While the nuns, onstage spectators, and the guillotine are audibly present in the scene, the priest participates solely through gesture. The surfacing of the Lacanian Real in the silent moment of traumatic shock that follows the guillotine’s first fall allows for intertextual references to the opera in Poulenc’s Sonate pour Flûte et Piano (1957) to function as a work of remembrance. digital.library.unt.edu/ark:/67531/metadc103288/
Optical Transparent Pmma Composite Reinforced By Coaxial Electrospun Pan Hollow Nanofibers
Electrospinning has been recognized as an efficient technique for the fabrication of polymer fibers. These electrospun fibers have many applications across a broad range of industries. In this research, optical transparent composites were successfully fabricated by embedding polyacrylonitrile (PAN) hollow nanofibers into poly (methyl methacrylate) (PMMA) matrix. The hollow PAN nanofibers were prepared by coaxial electrospinning. The PAN was used as the shell solution, and the mineral oil was used as the core solution. The resulting fibers were then etched with octane to remove the mineral oil from the core. The hollow PAN fibers were then homogeneously distributed in PMMA resins to fabricate the composite. The morphology, transmittance and mechanical properties of the PAN/PMMA composite were then characterized with an ESEM, TEM, tensile testing machine, UV-vis spectrometer and KD2 Pro Decagon device. The results indicated that the hollow nanofibers have relatively uniform size with one-dimensional texture at the walls. The embedded PAN hollow nanofibers significantly enhanced the tensile stress and the Young's modulus of the composite (increased by 58.3% and 50.4%, respectively), while having little influence on the light transmittance of the composite. The KD2 Pro device indicated that the thermal conductivity of the PMMA was marginally greater than the PAN/PMMA composite by 2%. This novel transparent composite could be used for transparent armor protection, window panes in vehicles and buildings, and airplane windshield etc. digital.library.unt.edu/ark:/67531/metadc271772/
