Knowledge management in virtual organizations: A study of a best practices knowledge transfer model.
Access: Use of this item is restricted to the UNT Community.
Knowledge management is a major concern for organizations today, and in spite of investments in technology, knowledge transfer remains problematic. This study sought to determine whether a relationship exists among participant group demographics (experience), implementation of an integrated knowledge transfer system (best practices model), knowledge transfer barriers, and knowledge transfer project (Web-based training) outcome in a virtual organization. The participant organization was a network of individuals and groups who practice patient advocacy in the research and treatment of cancer. These advocates volunteer in various capacities and are not collocated nor do they report to any single organizational entity. Volunteer participants were randomly assigned to a treatment or control condition. The treatment participants received a training supplement based upon a best practices knowledge transfer model. All participants reviewed a Web-based communications training module scheduled for deployment by the participant organization. Upon completion of the training program, participants were instructed to practice specific techniques from the program. At the end of this period, participants completed an online survey that measured demographics, perceived barriers to the knowledge transfer, and project outcome. Knowledge transfer barriers were defined as knowledge, source, recipient, and organizational context characteristics that inhibit the expected transfer. Project outcome was a composite score of items measuring completion time, budget, and satisfaction of the user. Multiple regression identified two significant predictor variables, source (the training program and implementation) and experience (amount of time spent in advocacy practice). Additional analyses found knowledge (causal ambiguity and unproven knowledge) and the experimental treatment condition to show a strong relationship with the explained variance of the dependent variable, knowledge transfer project outcome. Results suggest that an online training implementation is a valid tool for certain specific transfer design characteristics. Experience was a negative predictor of outcome, suggesting that participant-specific level of training material may produce improved outcome. Furthermore, knowledge in the form of evidence that the material is useful as well as explanation of the cause and effect linkage is a factor in a more successful transfer. Finally, the application of a knowledge transfer system designed around organization-specific variables shows promise as a factor in enhanced knowledge transfer in Web-based training in virtual organizations. Further research is suggested to provide additional insight into the predictive value of these variables. digital.library.unt.edu/ark:/67531/metadc4740/
Knowledge-of-Correct-Response vs. Copying-of-Correct-Response: a Study of Discrimination Learning
Copying prompts with subsequent unprompted practice produced better learning of simple discriminations than feedback only of a correct response without subsequent practice. The Copy condition promoted faster acquisition of accurate performance for all subjects, and shorter response latencies and durations for 3 of 4 subjects. The data support the findings of Barbetta, Heron, and Heward, 1993 as well as Drevno, Kimball, Possi, Heward, Garner III, and Barbetta, 1994. The author proposes that response repertoires are most valuable if easily reacquired at times after original learning. Thus, reacquisition performance data are emphasized. The data suggest that discriminations acquired by copying prompts may result in useful repertoires if a practice procedure is used which facilitates transfer of stimulus control from a formal prompt to a naturally occurring stimulus. digital.library.unt.edu/ark:/67531/metadc278437/
Knowledge-sharing Practices Among Turkish Peacekeeping Officers
The Turkish National Police (TNP) peacekeeping officers experience poor knowledge-sharing practices before, during, and after their tours of duty at the United Nations (UN) field missions, thus causing knowledge loss. The study aims to reveal the current knowledge-sharing practices of the TNP peacekeeping officers and proposes a knowledge-sharing system to share knowledge effectively. It also examines how applicable the knowledge management models are for their knowledge-sharing practices. In order to gain a better understanding about the knowledge-sharing practices of TNP officers, the researcher used a qualitative research method in this study. The researcher used semi-structured interviews in data collection. The participants were selected based on the non-probability and purposive sampling method. Content analysis and constant comparison was performed in the data analysis process. The most important knowledge sources of the peacekeeping officers are their colleagues, the Internet, and email groups. The peacekeepers recommend writing reports, organizing training programs, conducting exit interviews, adopting best practices, and creating a knowledge depository. The study uncovers that organizational culture, hierarchy, and physical proximity are significant factors that have a vital impact on knowledge sharing. Knowledge Conversion Model is substantially applicable for the knowledge-sharing practices of the TNP peacekeeping officer. digital.library.unt.edu/ark:/67531/metadc149588/
Knowledge synthesis in the biomedical literature: Nordihydroguaiaretic acid and breast cancer.
This dissertation refines knowledge synthesis from publicly accessible databases, based on the model of D.R. Swanson. Knowledge synthesis endeavors bring together two or more non-interactive literatures to create combinatorial research data on a specific topic. In this endeavor the biomedical literature was searched on the anti-neoplastic agent nordihydroguaiaretic acid (NDGA) for its potential role as a functional food in the chemoprevention of breast cancer. Bibliometric cocitation was utilized to identify complementary but non-interactive literatures in the disciplines of biomedicine and dietary science. The continuing specialization and fragmentation of the cancer literature degenerates the potential usefulness of cross-disciplinary research and information. As the biomedical sciences become more specialized the potential increases for isolation of discoveries and for failures to connect science to the needs of the people. Within the information science discipline several techniques are available to bridge the isolation between discoveries recorded in different sets of literatures. Electronic database searching with combinatorial keyword entries, syllogistic modeling and bibliometric author cocitation analysis are the principle techniques applied in this endeavor. The research questions are addressed to the absence or presence of human in vivo research on breast cancer with the potentially chemopreventative functional food NDGA. Utilizing a syllogistic model the literatures of functional foods, nordihydroguaiaretic acid and breast cancer were searched with designated combinatorial keywords. The documents retrieved were subjected to author cocitation analysis to demonstrate disjointness or connectivity of the two complementary literatures. The results demonstrated a possible preventative relationship between breast cancer in women and nordihydroguaiaretic acid, a phytochemical antioxidant and potential functional food. The results of this study are consistent with D.R. Swanson's pioneering work in knowledge synthesis. Swanson's methods can be used to identify non-interactive, disjoint literatures. Continuing support for his techniques has been demonstrated. digital.library.unt.edu/ark:/67531/metadc4387/
I. Korean address and reference terms between married men and women; II. Metaphorical extension in Korean compound verbs
Access: Use of this item is restricted to the UNT Community.
I. This study attempts to investigate the address and reference terms between Korean husbands and wives in different situations by means of the questionnaire. In addition to the results by the questionnaire, questions relating to gender, age, culture and society were partially answered through out this survey. II. This study attempts to analyze metaphorical extension of Korean compound verbs. The patterns found in Korean compound verbs are similar to the work of Abby and Chelliah. That is secondary verbs in the construction of compound verbs which have two sequential verbs have bleached meanings in the processes of grammaticalization. digital.library.unt.edu/ark:/67531/metadc2447/
Korean Electoral Behavior: The 1992 and 1997 Presidential Elections
This is a study of Korean presidential elections. Its purpose is to determine how Koreans voted in the 1992 and 1997 presidential elections and to examine the factors that contributed to winners. In addition, the study compares the two elections by developing three models: candidate choice, voter turnout and political interest models. Using post election data from the Korean Social Science Data Center a multinomial logit regression was used in the candidate choice model. It shows that Korean voters selected their candidates mainly in terms of interest in the elections, age, orientation toward the governing or opposition parties, the regional effects of the Southwest (Honam) and the Southeast (Youngnam), and the evaluation of merged parties in 1992 or a united candidacy of parties in 1997. A Monte Carlo simulation was also employed to test the traditional assumption of candidate strength. It indicates that Kim Young-Sam had a more cohesive support from his older supporters in the 1992 election while Kim Dae-Jung had a greater cohesive support from his older supporters in the 1997 election. Both Kim Young-Sam's and Kim Dae-Jung's loyalists were crucial to the winning candidates in the 1992 and 1997 elections respectively. How did people vote? To address this question a logit analysis of voter turnout was employed. Comparing the 1997 election to that of 1992 the findings suggest that low-probability voters in 1997 had: low efficacy, a negative evaluation of the Central Election Management Commission, claimed to be independent, young, and lived in areas other than Youngnam and Honam. Their lower turnout was a significant factor in the opposition candidate, Kim Dae-Jung's election. Finally, since political interest is closely related to political participation, an ordered logit model of political interest was developed. The results showed that the media and popularity of major candidates significantly contributed to Korean voters' interest in the elections. digital.library.unt.edu/ark:/67531/metadc2521/
Korean Students' Perceptions of the Effectiveness of their Internship Experiences in the Hospitality Industry in Korea
This research study assessed Korean students' perceptions and overall satisfaction levels regarding the effectiveness of their hospitality internship experiences. Relationships with demographic characteristics were identified. The sample was comprised of 74 senior-level university students enrolled in hospitality and/or tourism management programs who were completing an internship in Korea. Generally, students exhibited low agreement levels on the internship program aspects being investigated. Previous work experience was the most common factor influencing students' perceptions of their internship experiences. Agreement levels increased with length of prior work experience. Type of internship workplace, expectation of an employment offer, age and gender were found to influence students' perceptions of the internship experiences. digital.library.unt.edu/ark:/67531/metadc278968/
Korean studies in North America 1977-1996: A bibliometric study
This research is a descriptive bibliometric study of the literature of the field of Korean studies. Its goal is to quantitatively describe the literature and serve as a model for such research in other area studies fields. This study analyzed 193 source articles and 7,166 citations in the articles in four representative Korean and Asian studies journals published in North America from 1977 to 1996. The journals included in this study were Korean Studies (KS), the Journal of Korean Studies (JKS), the Journal of Asian Studies (JAS), and the Harvard Journal of Asiatic Studies (HJAS). Subject matters and author characteristics of the source articles were examined, along with various characteristics such as the form, date, language, country of origin, subject, key authors, and key titles of the literature cited in the source articles. Research in Korean studies falls within fourteen broad disciplines, but concentrated in a few disciplines. Americans have been the most active authors in Korean studies, followed closely by authors of Korean ethnicity. Monographic literature was used most. The mean age of publications cited was 20.87 and the median age of publications cited was 12. The Price Index of Korean studies as a whole is 21.9 percent. Sources written in English were most cited (47.1%) and references to Korean language sources amounted to only 34.9% of all sources. In general, authors preferred sources published in their own countries. Sources on history were cited most by other disciplines. No significant core authors were identified. No significant core literature were identified either. This study indicates that Korean studies is still evolving. Some ways of promoting research in less studied disciplines and of facilitating formal communication between Korean scholars in Korea and Koreanists in North America need to be sought in order to promote well-balanced development in the field. This study suggests that as many and as great a variety of titles in all formats as possible need to be collected to support research in Korean studies. digital.library.unt.edu/ark:/67531/metadc2254/
Korean Traditional Elements and Contemporary Compositional Techniques in Hyowon Woo’s Choral Music As Reflected in Gloria
Among native Korean choral composers, Hyowon Woo has emerged as one of the most significant representatives of choral genre, both in Korea and internationally. She has created a new style of choral music that combines traditional Korean musical elements with contemporary Western compositional techniques, in a synthesis that generates new sonorities and effects. Her choral music falls into three basic categories: music employing direct quotation of Korean folk tunes or other elements, which produce typical Korean sonorities; music using Western practices, which produce modern and Western flavors; and music combining Korean traditional methods with modern Western concepts. Hyowon Woo’s unique contribution to contemporary Korean choral music is ideally represented by her Gloria, which will form the basis for this study. Because traditional Korean music culture has such a strong presence and influence on her choral compositions, detailed knowledge of these elements are essential for the study and performance of her work. The combination of traditional Korean music and Western contemporary techniques lies at the core of her compositional style, and is the principal focus of this study. A detailed understanding of these stylistic elements, both Korean and Western, and how they work together to achieve the composer’s purpose and vision, is vital to achieving an informed performance of this work.  This study is intended to supply the conductor these needed tools and to add to the small but growing body of literature related to the performance practice not only of Woo’s significant body of choral compositions, but of Korean choral music in general. digital.library.unt.edu/ark:/67531/metadc149552/
Krzysztof Penderecki’s Divertimento/suite for Cello Solo (1994-2013): a Stylistic Analysis and Performance Guide
Penderecki made a tremendous variety of contributions to the cello repertoire. His profound respect for tradition and for his past is deeply appreciated by both performers and audiences. In each individual composition, he explored the cello’s sonorous possibilities and created a new technical and musical palette for the instrument. He worked with legendary, world-renowned cellists who not only gave the premieres of his works but also established deep friendships with him. The Divertimento/Suite for Cello Solo (1994-2013), a compilation of miniature movements, each with its sophisticated structure, demonstrates Penderecki’s three compositional style periods. Baroque and Romantic elements in each movement are achieved within their style characteristics. Penderecki’s Divertimento/Suite for Violoncello Solo is composed of eight contrasting movements that were written during a nineteen-year period. The work is characterized by a Neo-Romantic aesthetic and utilizes the cello’s dark lyrical tones with a variety of timbre and tonal contrasts. The purpose of the present study is to create a practical performance guide to this important musical work with a detailed stylistic, textural, and motivic analysis of all eight movements. Although there are many published documents and analyses of Penderecki’s orchestral, choral, chamber and other solo pieces, the Divertimento/Suite for Cello Solo has yet to be thoroughly researched and discussed in the extant cello literature. It is the lack of research concerning this work that prompts this important study. This analysis will serve to outline the unifying compositional procedures of the work and explain the special instrumental techniques employed. With its illustrations of the motivic, harmonic and the textural relationships of each movement, this study serves as a twentieth-century performance guide for the cello world. digital.library.unt.edu/ark:/67531/metadc500083/
Kurt Weill: a Song Composer in Wartime with Three Recitals of Selected Works of Mozart, Strauss, Bach, Schubert, and Others
During World War II the composer Kurt Weill was in America writing for the Broadway stage. On August 27, 1943, he became an American citizen and was eager to volunteer his talent to the American war effort. Among his many wartime musical contributions are fourteen songs, all with war-related texts, which can be divided into three distinct groups: the American propaganda songs (8), the German propaganda songs (2), and the Walt Whitman songs (4). It is the purpose of this paper to present a comparative analysis of a representative group of these war songs (two from each group) in order to illustrate Weill's musical versatility. The American propaganda songs were written in a purely popular song style; sung by Broadway actors; directed toward an American audience; with texts by the Broadway lyricist Oscar Hammerstein II and the Hollywood movie executive Howard Dietz. The German propaganda songs were written in a cabaret song style; sung in German by Weill's wife, Lotte Lenya; directed toward a German audience behind enemy lines; with texts by the German playwright Bertolt Brecht and the German cabaret writer Walter Mehring. The Four Walt Whitman Songs were written in a classical art song style; sung by classically trained singers; directed toward a general audience; with texts by the nineteenth-century American poet Walt Whitman. After an initial discussion of Weill's early musical training and career in Europe, his exile from Germany, his reception in America, and his contributions to the American war effort, each group of war songs is analyzed musically, textually, vocally, in reference to the audience to whom it was directed, and with regards to vocal performance practice. Comparisons and conclusions are then drawn. Kurt Weill's war songs are valuable for musical study, both in terms of examining his ability to write equally well in various musical styles and as an opportunity to learn more about music and society during the turbulent years' of World War II. digital.library.unt.edu/ark:/67531/metadc277791/

L2 acquisition of Spanish telic se constructions
This thesis examines the acquisition of the aspectual properties of the Spanish se in transitive constructions by L2 learners of Spanish. Based on a parameterized distinction of the telic features in English and Spanish, this study investigates whether second language (L2) learners are able to reset the aspectual value of the English parameter to that of Spanish in their interlanguage grammar. Results indicate that L2 learners' responses to a picture interpretation task vary according to proficiency levels. Low-intermediate and intermediate learners did not differentiate between telic and atelic constructions whereas advanced learners successfully acquired the telic properties of the transitive se constructions. Results were interpreted in the light of current theories of second language acquisition and the mental representation of aspect in interlanguage. digital.library.unt.edu/ark:/67531/metadc2596/
En La Frontera Entre La Vida Y La Muerte: a Study of Women Reporters on the Us–mexico Border
In 2008 Ciudad Juarez erupted in a violent drug war. The Sinaloa Cartel and Juarez Cartel were in a battle for the lucrative drug route used to smuggle drugs into the United States, while President Felipe Calderon was waging his own war against all the drug cartels. During the height of the violence women journalists emerged on the front lines to tell the stories of Juarez. They risked their lives and dared to tell a story that others refused to. This mixed-method study examines frames used most often in the coverage of the drug war in Ciudad Juarez from 2008-2010. It examines The New York Times, the El Paso Times, and El Norte and also examines articles by the sex of the reporter. It also used in-depth interviews of both Mexican and American woman journalists who covered the drug war in Juarez to examine which themes developed about the reporter’s experiences in covering the drug war. digital.library.unt.edu/ark:/67531/metadc500186/

Laboratory and field studies of cadmium effects on Hyalella azteca in effluent dominated systems.
Laboratory single-species toxicity tests are used to assess the effects of contaminants on aquatic biota. Questions remain as to how accurately these controlled toxicity tests predict sitespecific bioavailability and effects of metals. Concurrent 42-day Hyalella azteca exposures were performed with cadmium and final treated municipal effluent in the laboratory and at the University of North Texas Stream Research Facility. Further laboratory testing in reconstituted hard water was also conducted. Endpoints evaluated include survival, growth, reproduction, and Cd body burden. My results demonstrate that laboratory toxicity tests may overestimate toxicity responses to cadmium when compared to effluent dominated stream exposures. Discrepancies between endpoints in the three tests likely resulted from increased food sources and decreased cadmium bioavailability in stream mesocosms digital.library.unt.edu/ark:/67531/metadc4291/

A Laboratory Study of the Asiatic Clam (Corbicula fluminea Müller) as Influenced by Substrate, Food Source and Water Type
Growth of Corbicula fluminea was monitored in the laboratory. Three experiments were conducted. Experiment I utilized three substrates and one food type. Experiment II utilized three substrates and two food types. Experiments I and II were conducted to determine if substrate type or food type effected growth. Experiment III used no substrates, one food type and was conducted to determine growth response to different types of water. Clams were maintained in three substrates: sand, gravel and clay. Clams were also maintained without substrate. Growth was monitored by measuring shell length (mm) and recording the weight (mg) of clams over a period of thirty days. At the end of the test period data were evaluated for normality and homogeneity. digital.library.unt.edu/ark:/67531/metadc279067/
Labor's Attitude toward Administered Prices
What effect does controlled price have upon the profits of business or of industrial concerns, upon the wages paid to workers, upon the public demand for articles whose price is controlled, upon the volume of production, and upon the public attitude toward those businesses whose products are protected by controlled prices? What are the attitudes of organized labor toward the principle of administered or controlled prices? What are the reasons advanced by both management and labor for and against controlled prices? What is the over-all or long-term influence of controlled prices upon the total economic progress of the nation? These are some of the questions which will be considered in this study. digital.library.unt.edu/ark:/67531/metadc107862/
Lack of Evaluation as Evaluation: Analysis of an African American Woman’s Narrative
This thesis examines an African American woman’s narrative about the day that her daughter was shot. Like many personal narratives of “frightening experiences,” the speaker in this narrative highlights the peak of her story, making sure her point is salient. In earlier analyses, it has been shown that evaluation tends to cluster around the peak of the narrative. In “The day my daughter got shot” we see that this event-filled narrative is not evaluated as predicted as there is no increased usage of evaluative devices at one single point in the narrative. Instead, it is a change in patterning of a number of linguistic and paralinguistic devices that conspire to bring special attention to the peak of the narrative. By examining multiple devices at once, it is seen that they create a cumulative effect that makes the story interesting and exciting, resulting in a successful narrative. digital.library.unt.edu/ark:/67531/metadc84295/
Lactate Dehydrogenase of Hymenolepis Diminuta: Isolation and Characterization
Lactate dehydrogenase was isolated in pure form from crude extract of the cestode Hymenoleois diminuta by heat treatment and column chromatography. The purified enzyme has a specific activity of 106 units per mg protein. The molecular weight of the purified protein was 75,000 as determined by Sephadex gel filtration and analytical ultracentrifugation. An equilibrium ultracentrifugation study suggests a subunit molecular weight of 39,000. From these data, a dimer form of the native enzyme is proposed. digital.library.unt.edu/ark:/67531/metadc131460/
Lamb's Self-Revelations as "Elia"
The purpose of this thesis is to determine the nature of Charles Lamb as revealed in his Elia essays. To this end, these essays form the major portion of the text. The general procedure for ascertaining what these excerpts indicate is as follows: first, the characteristics of Charles Lamb are determined from a study of the Elia essays; second, these characteristics are considered in relation to information derived from biographies. Careful attention is given to significant discrepancies between the essays and other sources. digital.library.unt.edu/ark:/67531/metadc130917/
Laminar Natural Convection From Isothermal Vertical Cylinders
Laminar natural convection heat transfer from the vertical surface of a cylinder is a classical subject, which has been studied extensively. Furthermore, this subject has generated some recent interest in the literature. In the present investigation, numerical experiments were performed to determine average Nusselt numbers for isothermal vertical cylinders (103 < RaL < 109, 0.5 < L/D <10, and Pr = 0.7) with and without an adiabatic top in a quiescent ambient environment which will allow for plume growth. Results were compared with commonly used correlations and new average Nusselt number correlations are presented. Furthermore, the limit for which the heat transfer results for a vertical flat plate may be used as an approximation for the heat transfer from a vertical cylinder was investigated. digital.library.unt.edu/ark:/67531/metadc177190/

Landscape forest modeling of the Luquillo Experimental Forest, Puerto Rico.
This thesis contributes to modeling the dynamics of forest community response to environmental gradients and disturbances over a mountain landscape. A gap model (FACET) was parameterized for species of various forest types (Tabonuco, Colorado, Dwarf and Palm), for many terrain conditions and was modified and extended to include species response to excess soil moisture and hurricanes. Landscape cover types were defined by dominance of species of each forest type and canopy height. Parameters of the landscape model (MOSAIC) were calculated from multiple runs of FACET. These runs were determined by combining terrain variables (elevation and soil) and hurricane risk. MOSAIC runs were analyzed for distribution patterns. Geographic Information Systems software was used to process terrain variables, hurricane risk and MOSAIC model output. digital.library.unt.edu/ark:/67531/metadc3362/

Language and Identity in Post-1800 Irish Drama
Using a sociolinguistic and post-colonial approach, I analyze Irish dramas that speak about language and its connection to national identity. In order to provide a systematic and wide-ranging study, I have selected plays written at approximately fifty-year intervals and performed before Irish audiences contemporary to their writing. The writers selected represent various aspects of Irish society--religiously, economically, and geographically--and arguably may be considered the outstanding theatrical Irish voices of their respective generations. Examining works by Alicia LeFanu, Dion Boucicault, W.B. Yeats, and Brian Friel, I argue that the way each of these playwrights deals with language and identity demonstrates successful resistance to the destruction of Irish identity by the dominant language power. The work of J. A. Laponce and Ronald Wardhaugh informs my language dominance theory. Briefly, when one language pushes aside another language, the cultural identity begins to shift. The literature of a nation provides evidence of the shifting perception. Drama, because of its performance qualities, provides the most complex and complete literary evidence. The effect of the performed text upon the audience validates a cultural reception beyond what would be possible with isolated readers. Following a theoretical introduction, I analyze the plays in chronological order. Alicia LeFanu's The Sons of Erin; or, Modern Sentiment (1812) gently pleads for equal treatment in a united Britain. Dion Boucicault's three Irish plays, especially The Colleen Bawn (1860) but also Arrah-na-Pogue (1864) and The Shaughraun (1875), satirically conceal rebellious nationalist tendencies under the cloak of melodrama. W. B. Yeats's The Countess Cathleen (1899) reveals his romantic hope for healing the national identity through the powers of language. However, The Only Jealousy of Emer (1919) and The Death of Cuchulain (1939) reveal an increasing distrust of language to mythically heal Ireland. Brian Friel's Translations (1980), supported by The Communication Cord (1982) and Making History (1988), demonstrates a post-colonial move to manipulate history in order to tell the Irish side of a British story, constructing in the process an Irish identity that is postnational. digital.library.unt.edu/ark:/67531/metadc277916/
Language and the Art of Writing
Access: Use of this item is restricted to the UNT Community.
I start writing by conjuring up an image in my mind. Sometimes it will be something that I have thought about for a while, sometimes it will be something that I sit around attempting to create. Either way, it is simply the idea that I need in order to get started. People will say, "Just sit down and write" which I can do, but it does not mean I will end up anywhere worthwhile. In my writing I need a focus. I need an idea or just one image to get me writing and I can base an entire story off of that one image. I think the reason this works for me is because in my mind it is an illustration and always something that is vibrant and unique. I want the image to stand out and to mean something because I feel that it comes to me for a specific reason, I just have to piece it all together and let the characters and plot unfold for themselves. People often say this, that the characters end up running the story. I think this is true, but in my case my stories are not so driven by character or plot as they are by language. A language driven piece can be a difficult thing to manipulate because it needs to have some direction and some purpose other than just being pleasing to the ear/mind/reader. And what is the point of a language driven piece? digital.library.unt.edu/ark:/67531/metadc5230/
A Language and Visual Interface to Specify Complex Spatial Pattern Mining
Access: Use of this item is restricted to the UNT Community.
The emerging interests in spatial pattern mining leads to the demand for a flexible spatial pattern mining language, on which easy to use and understand visual pattern language could be built. It is worthwhile to define a pattern mining language called LCSPM to allow users to specify complex spatial patterns. I describe a proposed pattern mining language in this paper. A visual interface which allows users to specify the patterns visually is developed. Visual pattern queries are translated into the LCSPM language by a parser and data mining process can be triggered afterwards. The visual language is based on and goes beyond the visual language proposed in literature. I implemented a prototype system based on the open source JUMP framework. digital.library.unt.edu/ark:/67531/metadc5408/

Language Choice in the ESL and FL Classrooms: Teachers and Students Speak Out
This paper compares English as a second language (ESL) and foreign language (FL) teachers' and students' perspectives regarding target language (TL) and first language (L1) use in the respective classrooms. Teachers and students were given questionnaires asking their opinions of a rule that restricts students' L1 use. Questionnaires were administered to 46 ESL students, 43 FL students, 14 ESL teachers, and 15 FL teachers in Texas secondary public schools. Results were analyzed using SPSS and R. Results demonstrated an almost statistical difference between perspectives of ESL and FL students regarding TL and L1 use, while teacher results demonstrated no statistical difference between the groups.

Language Contact in the Inner City: the Acquisition of AAVE Features by Bilingual Hispanic Adolescents
Sociolinguists working in Northern urban areas have shown that Hispanics who come in contact with African Americans sometimes acquire features of African American vernacular English (AAVE). However, the acquisition of AAVE features by Hispanics in the South has yet to be documented. Specifically, no one has studied the kind of English that Hispanics in Texas are acquiring. The present study investigates this issue through research in an inner-city area of Dallas: Oak Cliff. During the past twenty-five years, the population of Oak Cliff has changed from a largely African American community to include a substantial number of Hispanics. Though their neighborhoods remain fairly separate, sports and gangs provide an arena for extended contact. This study investigates the extent to which AAVE grammatical features are being acquired by bilingual Hispanic adolescents who hang out with African Americans. The analysis for this paper focuses on the relationship between contact and depth of acquisition of AAVE syntactic constraints on the use the copula (is/are, be). Preliminary results show that be+V+ing as an habitual form has been incorporated into the grammar of these subjects, suggesting fundamental changes towards an AAVE grammatical system. digital.library.unt.edu/ark:/67531/metadc279116/
Language Drift in English : Gender Loss and Semantic Change
In parallel passages from Old and Middle English and in noun cognates from Modern English, Old English, and Modern German, the most discernible elements of language drift are gender loss and word meaning change, respectively. They can be observed, discussed, and calculated to show a definite progression toward the development of Modern English. digital.library.unt.edu/ark:/67531/metadc131021/
The Language of Color in Shelley's Prometheus Unbound
On the premise that examination of a poet's language can provide a valid and significant approach to the study of a work of art, this thesis proposes to make such a study of Prometheus Unbound, the major poetical work of Percy Bysshe Shelley, with specific attention to his use of color language. digital.library.unt.edu/ark:/67531/metadc163943/
Language Policy, Protest and Rebellion
The hypothesis that language discrimination contributes to protest and/or rebellion is tested. Constitutional language policy regarding administrative/judicial, educational and other matters is measured on three separate scales developed for this study; the status of each minority group's language under its country's policy is measured by another set of scales. Protest and rebellion variables are taken from Gurr's Minorities at Risk study. Findings include an indication that group language status contributes positively to protest and rebellion until a language attains moderate recognition by the government, at which point status develops a negative relationship with protest and rebellion, and an indication that countries with wider internal variations in their treatment of language groups experience higher levels of protest and rebellion on the part of minority groups. digital.library.unt.edu/ark:/67531/metadc2790/

Laser Cutting Machine: Justification of initial costs
The Industrial Laser is firmly established in metalcutting as the tool of choice for many applications. The elevator division of Montgomery KONE Inc., in an effort to move towards quality, ontime, complete deliveries and 100% customer satisfaction, decided to invest in new equipment to improve manufacturing processes. A huge investment is proposed for a laser-cutting machine. It is the responsibility of Manufacturing Engineering to direct the management by justifying its benefits, which includes payback time and financial gains. Factors such as common line cutting, automated material handling system and cutting time were involved in justification of the initial cost of a laser-cutting machine. Comparative statistics on appropriate factors accurately determine and justify the initial cost of a laser-cutting machine. digital.library.unt.edu/ark:/67531/metadc2787/
Laser Deposition, Heat-treatment, and Characterization of the Binary Ti-xmn System
The present research seeks to characterization of an additively manufactured and heat-treated Ti-xMn gradient alloy, a binary system that has largely been unexplored. In order to rapidly assess this binary system, compositionally graded Ti-xMn (0<x<15 wt%) specimens were fabricated using the LENS (Laser Engineered Net Shaping) and were subsequently heat-treated and characterized using a wide range of techniques. Microstructural changes with respect to the change in thermal treatments, hardness and chemical composition were observed and will be presented. These include assessments of both continuous cooling, leading to observations of both equilibrium and metastable phases, including the titanium martensites, and to direct aging studies looking for composition regimes that produce highly refined alpha precipitates – a subject of great interest given recent understandings of non-classical nucleation and growth mechanisms. The samples were characterized using SEM, EDS, TEM, and XRD and the properties probed using a Vickers Microhardness tester. digital.library.unt.edu/ark:/67531/metadc500073/
Laser Modified Alumina: a Computational and Experimental Analysis
Laser surface modification involves rapid melting and solidification is an elegant technique used for locally tailoring the surface morphology of alumina in order to enhance its abrasive characteristics. COMSOL Multiphysics® based heat transfer modeling and experimental approaches were designed and used in this study for single and multiple laser tracks to achieve densely-packed multi-facet grains via temperature history, cooling rate, solidification, scanning electron micrographs, and wear rate. Multi-facet grains were produced at the center of laser track with primary dendrites extending toward the edge of single laser track. The multiple laser tracks study indicates the grain/dendrite size increases as the laser energy density increases resulting in multiplying the abrasive edges which in turn enhance the abrasive qualities. digital.library.unt.edu/ark:/67531/metadc177232/
Laser Surface Modification on Az31b Mg Alloy for Bio-wettability
Laser surface modification of AZ31B Magnesium alloy changes surface composition and roughness to provide improved surface bio-wettability. Laser processing resulted in phase transformation and grain refinement due to rapid quenching effect. Furthermore, instantaneous heating and vaporization resulted in removal of material, leading the textured surface generation. A study was conducted on a continuum-wave diode-pumped ytterbium laser to create multiple tracks for determining the resulting bio-wettability. Five different laser input powers were processed on Mg alloy, and then examined by XRD, SEM, optical profilometer, and contact angle measurement. A finite element based heat transfer model was developed using COMSOL multi-physics package to predict the temperature evolution during laser processing. The thermal histories predicted by the model are used to evaluate the cooling rates and solidification rate and the associated changes in the microstructure. The surface energy of laser surface modification samples can be calculated by measuring the contact angle with 3 different standard liquid (D.I water, Formamide, and 1-Bromonaphthalen). The bio-wettability of the laser surface modification samples can be conducted by simulated body fluid contact angle measurement. The results of SEM, 3D morphology, XRD, and contact angle measurement show that the grain size and roughness play role for wetting behavior of laser processing Mg samples. Surface with low roughness and large grain size performs as hydrophilicity. On the contrast, surface with high roughness and small grain size performs as hydrophobicity. digital.library.unt.edu/ark:/67531/metadc407788/
Laser Surface Treatment of Amorphous Metals
Amorphous materials are used as soft magnetic materials and also as surface coatings to improve the surface properties. Furthermore, the nanocrystalline materials derived from their amorphous precursors show superior soft magnetic properties than amorphous counter parts for transformer core applications. In the present work, laser based processing of amorphous materials will be presented. Conventionally, the nanocrystalline materials are synthesized by furnace heat treatment of amorphous precursors. Fe-based amorphous/nanocrystalline materials due to their low cost and superior magnetic properties are the most widely used soft magnetic materials. However, achieving nanocrystalline microstructure in Fe-Si-B ternary system becomes very difficult owing its rapid growth rate at higher temperatures and sluggish diffusion at low temperature annealing. Hence, nanocrystallization in this system is achieved by using alloying additions (Cu and Nb) in the ternary Fe-Si-B system. Thus, increasing the cost and also resulting in reduction of saturation magnetization. laser processing technique is used to achieve extremely fine nanocrystalline microstructure in Fe-Si-B amorphous precursor. Microstructure-magnetic Property-laser processing co-relationship has been established for Fe-Si-B ternary system using analytical techniques. Laser processing improved the magnetic properties with significant increase in saturation magnetization and near zero coercivity values. Amorphous materials exhibit excellent corrosion resistance by virtue of their atomic structure. Fe-based amorphous materials are economical and due to their ease of processing are of potential interest to synthesize as coatings materials for wear and corrosion resistance applications. Fe-Cr-Mo-Y-C-B amorphous system was used to develop thick coatings on 4130 Steel substrate and the corrosion resistance of the amorphous coatings was improved. It is also shown that the mode of corrosion depends on the laser processing conditions. The microstructure evolution and the corrosion mechanisms operating are evaluated using post processing and post corrosion analysis. digital.library.unt.edu/ark:/67531/metadc500194/
The Last Laugh: Selected Edwardian Punch Cartoons of Edward Linley Sambourne
The illustrative work of Edward Linley Sambourne for Punch magazine during the period 1901-1910 addresses a myriad of political topics prevalent during the Edwardian period in British history. This thesis examines two of those topics - Women's Suffrage and Socialism - through their artistic treatment by one of Britain's most influential periodicals. Through a study of the historical context and iconography of selected cartoons-of-the-week, one is better equipped to understand and appreciate the meaning, message, and humor in the cartoons. Chapter 1 introduces the Sambourne, Punch magazine, and the Edwardian period in general. Chapters 2 and 3 discuss four Women's Suffrage cartoons and four Socialism cartoons respectively. Chapter 4 draws conclusions regarding Sambourne's techniques as a cartoonist as well as the relationship between the text and image in his illustrations. digital.library.unt.edu/ark:/67531/metadc2793/
Late adolescents' parental, peer, and romantic attachments as they relate to affect regulation and risky behaviors.
The current study examined the relationships among attachment styles to parent, peer, and romantic partner, ability to regulate emotion, as well as engagement in sexual behaviors and substance use. Attachment theory and previous research suggests that an individual learns how to manage emotions through the modeling of appropriate techniques and a stable sense of self-worth. These two aspects develop through a secure attachment bond with an important figure. When an individual does not have a secure attachment bond in which to practice adaptive affect regulation strategies, he/she may attempt to manage emotions through external means, such as sexual behaviors or substance use. Overall, results supported these associations, with some notable exceptions. Across attachment sources a secure attachment style was related to lower levels of psychological distress and less engagement in substance use. In contrast to the findings from earlier studies, affect regulation did not mediate the relationship between attachment and substance use, and engagement in sexual behaviors was not significantly related to either attachment style or affect regulation. digital.library.unt.edu/ark:/67531/metadc9083/
Latent Transition Analysis of Pre-service Teachers' Efficacy in Mathematics and Science
This study modeled changes in pre-service teacher efficacy in mathematics and science over the course of the final year of teacher preparation using latent transition analysis (LTA), a longitudinal form of analysis that builds on two modeling traditions (latent class analysis (LCA) and auto-regressive modeling). Data were collected using the STEBI-B, MTEBI-r, and the ABNTMS instruments. The findings suggest that LTA is a viable technique for use in teacher efficacy research. Teacher efficacy is modeled as a construct with two dimensions: personal teaching efficacy (PTE) and outcome expectancy (OE). Findings suggest that the mathematics and science teaching efficacy (PTE) of pre-service teachers is a multi-class phenomena. The analyses revealed a four-class model of PTE at the beginning and end of the final year of teacher training. Results indicate that when pre-service teachers transition between classes, they tend to move from a lower efficacy class into a higher efficacy class. In addition, the findings suggest that time-varying variables (attitudes and beliefs) and time-invariant variables (previous coursework, previous experiences, and teacher perceptions) are statistically significant predictors of efficacy class membership. Further, analyses suggest that the measures used to assess outcome expectancy are not suitable for LCA and LTA procedures. digital.library.unt.edu/ark:/67531/metadc30425/
Latin Mass for Choir, Orchestra, Soprano and Mezzo-Soprano Soloists
The Latin Mass is a musical composition in five movements, scored for large choir, standard orchestra, and two soloists. The movements are the standard parts of the Roman Catholic Mass Ordinary. The language is set mainly in Latin with two exceptions: the Kyrie movement is set in Greek (which is the standard Roman Catholic setting), and the Credo is simultaneously recited in English and sung in Latin. The work is scored using conventional notation techniques and employs rather conservative technical demands on both the choir and orchestra. No extended techniques are required of any of the performers. It is set in a modal harmonic language. digital.library.unt.edu/ark:/67531/metadc4234/

Latino Students’ School Counseling Needs: an Exploratory Needs Assessment
The purpose of this study was to examine Latino/a student preferences for school counselor activities. The primary focus of research was to determine what school counseling activities Latino/a students perceived as important and which school counseling activities Latino/a high school students perceived as satisfying. The researcher pursued this purpose through administration of a survey instrument developed by the researcher. The instrument consisted of 14 demographic items and 42 5-point Likert scale items based on the domains described in the ASCA’s national model and current literature on experiences of Latino/a adolescents. The sample was comprised of 210 Latino/a high school students from five high schools in three school districts in the suburbs of a large Southwestern U.S. metroplex. The study population consisted of 94 female and 115 male participants ranging in age from 14 to 20 years old with the median age of 17.54 years. Overall, students preferred school counseling activities focusing on college and career readiness. According to the results of this study, students indicated that although they believed college and career activities to be important, they were not satisfied with how their school counselors provided those activities. Multiple regression analyses were utilized to determine which demographic variables were significant predictors of respondents’ perceptions of importance. Results indicated student perceptions of importance did not vary across grades, economic levels, genders, or cultural differences. The results, limitations, and suggestions for school counseling programs were provided within the report. digital.library.unt.edu/ark:/67531/metadc149642/
