De novo prediction of the ground state structure of transition metal complexes.
Access: Use of this item is restricted to the UNT Community.
One of the main goals of computational methods is to identify reasonable geometries for target materials. Organometallic complexes have been investigated in this dissertation research, entailing a significant challenge based on transition metal diversity and the associated complexity of the ligands. A large variety of theoretical methods have been employed to determine ground state geometries of organometallic species. An impressive number of transition metals entailing diverse isomers (e.g., geometric, spin, structural and coordination), different coordination numbers, oxidation states and various numbers of electrons in d orbitals have been studied. Moreover, ligands that are single, double or triple bonded to the transition metal, exhibiting diverse electronic and steric effects, have been investigated. In this research, a novel de novo scheme for structural prediction of transition metal complexes was developed, tested and shown to be successful. digital.library.unt.edu/ark:/67531/metadc4669/
Now All the Fingers of This Tree
Now All the Fingers of This Tree is a work in two movements based upon a poem of the same name by E. E. Cummings. It is divided into two movements: The first movement is scored for nine part solo soprano, where one performer records each of the nine vocal lines. The second movement is an electro-acoustic work derived from four phrases of the original recording of the first movement. Total duration of the work is approximately 19 minutes. The paper provides a detailed analysis of both movements as well as a discussion on usage of text, problems addressed with traditional notation techniques, and technology utilized in the production of the work. digital.library.unt.edu/ark:/67531/metadc4166/
"Now His Time Really Seems to Have Come": Ideas about Mahler's Music in Late Imperial and First Republic Vienna
In Vienna from about 1918 until the 1930s, contemporaries perceived a high point in the music-historical significance of Mahler's works, with regard to both the history of compositional style and the social history of music. The ideas and meanings that became attached to Mahler's works in this milieu are tied inextricably to the city's political and cultural life. Although the performances of Mahler's works under the auspices of Vienna's Social Democrats are sometimes construed today as mere acts of political appropriation, David Josef Bach's writings suggest that the innovative and controversial aspects of Mahler's works held social value in line with the ideal of Arbeiterbildung. Richard Specht, Arnold Schoenberg, and Theodor Adorno embraced oft-criticized features in Mahler's music, regarding the composer as a prophetic artist whose compositional style was the epitome of faithful adherence to one's inner artistic vision, regardless of its popularity. While all three critics addressed the relationship between detail and whole in Mahler's music, Adorno construed it as an act of subversion. Mahler's popularity also affected Viennese composers during this time in obvious and subtle ways. The formal structure and thematic construction of Berg's Chamber Concerto suggest a compositional approach close to what his student Adorno described a few years later regarding Mahler's music. digital.library.unt.edu/ark:/67531/metadc12141/
NSAID effect on prostanoids in fishes: Prostaglandin E2 levels in bluntnose minnows (Pimephales notatus) exposed to ibuprofen.
Prostanoids are oxygenated derivatives of arachidonic acid with a wide range of physiological effects in vertebrates including modulation of inflammation and innate immune responses. Nonsteroidal anti-inflammatory drugs (NSAIDs) act through inhibition of cyclooxygenase (COX) conversion of arachidonic acid to prostanoids. In order to better understand the potential of environmental NSAIDS for interruption of normal levels COX products in fishes, we developed an LC/MS/MS-based approach for tissue analysis of 7 prostanoids. Initial studies examining muscle, gut and gill demonstrated that prostaglandin E2 (PGE2) was the most abundant of the measured prostanoids in all tissues and that gill tissue had the highest and most consistent concentrations of PGE2. After short-term 48-h laboratory exposures to concentrations of 5, 25, 50 and 100 ppb ibuprofen, 50.0ppb and 100.0 ppb exposure concentrations resulted in significant reduction of gill tissue PGE2 concentration by approximately 30% and 80% respectively. The lower exposures did not result in significant reductions when compared to unexposed controls. Measured tissue concentrations of ibuprofen indicated that this NSAID had little potential for bioaccumulation (BCF 1.3) and the IC50 of ibuprofen for inhibition of PGE2 production in gill tissue was calculated to be 0.4 µM. Short-term laboratory exposure to ibuprofen did not result in significant alteration of concentrations of PGE2 at environmentally relevant concentrations. digital.library.unt.edu/ark:/67531/metadc11058/

Nuclear Magnetic Resonance Spectra of Some 1,2,4-triazoles
In the work undertaken here, NMR has been used to ascertain the structure of some 1,2,4-triazoles. The investigation provides information concerning the structure of potentially tautomeric triazoles such as hydroxy- and aminotriazole. Connected with this aspect of triazole chemistry is the larger problem of mesohydric tautomerism. The present study also yields information for a comparison of substituent effects in triazoles, N-heteroaromatic substances and benzene. digital.library.unt.edu/ark:/67531/metadc164245/

Nuclear Waste Policy Act
The Nuclear Waste Policy Act (NWPA) supports the use of deep geologic repositories for the safe storage and/or disposal of radioactive waste. The Act establishes procedures to evaluate and select sites for geologic repositories and for the interaction of state and federal governments. It also provides a timetable of key milestones the federal agencies must meet in carrying out the program. The NWPA assigns the Department of Energy (DOE) the responsibility to site, build, and operate a deep geologic repository for the disposal of high-level waste and spent nuclear fuel. It directs EPA to develop standards for protection of the general environment from offsite releases of radioactive material in repositories. The Act directs the Nuclear Regulatory Commission (NRC) to license DOE to operate a repository only if it meets EPA's standards and all other relevant requirements. digital.library.unt.edu/ark:/67531/metadc11977/
Nucleotide Inhibition of Glyoxalase II
The glyoxalase system mediates the conversion of methylglyoxal, a toxic ketoaldehyde, to D-lactic acid. The system is composed of two enzymes, glyoxalase I (Glo-I) and glyoxalase II (Glo-II), and exhibits an absolute requirement for a catalytic quantity of glutathione (GSH). Glo-I catalyzes the isomerization of a hemithioacetal, formed non-enzymatically from methylglyoxal and GSH, to the corresponding a -D-hydroxyacid thioester, s-D-lactoylglutathione (SLG). Glo-II catalyzes the irreversible breakdown of SLG to D-lactate and GSH. We have observed that ATP or GTP significantly inhibits the Glo-II activity of tissue homogenates from various sources. We have developed a rapid, one step chromatography procedure to purify Glo-II such that the purified enzyme remains "sensitive" to inhibition by ATP or GTP (Glo-II-s). Studies indicate that inhibition of Glo-II-s by nucleotides is restricted to ATP, GTP, ADP, and GDP, with ATP appearing most effective. Kinetics studies have shown that ATP acts as a partial non-competitive inhibitor of Glo-II-s activity, and further suggest that two kinetically distinguishable forms of the enzyme exist. The sensitivity of pure Glo-II-s to nucleotide inhibition is slowly lost on storage even at -80° C. This loss is accelerated at higher temperatures or in the presence of ATP. Kinetics studies on the resultant "insensitive" enzyme (Glo-II-i) show that a significant reduction of the affinity of the enzyme for the substrate, SLG, occurs and further suggest that only one form of the enzyme is kinetically distinguishable after "de-sensitization". Tryptophan fluorescence studies of the two enzyme preparations suggest that a subtle conformational change in the enzyme has occurred during de-sensitization. We have also observed that Glo-II-i is "resensitized" to nucleotide inhibition after incubation in the presence of a reagent that reduces disulfide bonds. The resensitized enzyme exhibits an increased KM value similar to that of the original Glo-II-s. Kinetics studies show that ATP or GTP again act as partial non-competitive inhibitors of the resensitized enzyme and suggest that only one form of the enzyme is present. The physiological significance of the two enzyme forms is discussed. digital.library.unt.edu/ark:/67531/metadc2183/
Nucleotide Sequence of a Bovine Arginine Transfer RNA Gene
A single plaque-pure lambda clone designated λBA84 that hybridized to a ˆ32P-labeled bovine arginine tRNA was isolated from a bovine genomic library harbored in a lambda bacteriophage vector. A 2.3-kilobase segment of this clone was found to contain an arginine transfer RNAccg gene by Southern blot hybridization analysis and dideoxyribonucleotide DNA sequencing. This gene contains the characteristic RNA polymerase III split promoter sequence found in all eukaryotic tRNAs and a potential RNA polymerase III termination site, consisting of four consecutive thymine residues, in the 3'-flanking region. Several possible cis-acting promoter elements were found within the 5'-flanking region of the sequenced gene. The function of these elements, if any, is unknown. digital.library.unt.edu/ark:/67531/metadc278753/

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/
Nutrient Effects on Autofragmentation of Myriophyllum Spicatum L.
A 2 x 2 factorial design investigated effects of sediment nitrogen and water potassium levels on autofragment production. Reduced nitrogen levels significantly increased autofragment production whereas potassium levels did not significantly alter production. Up to 50% of autofragment production abscised from parent plants grown under low nitrogen conditions compared to 12% or less under high nitrogen conditions. digital.library.unt.edu/ark:/67531/metadc279354/
Nutritional, Demographic, and Behavioral DIfferences between Subjects from Two Similar WIC Clinics with Different Prevalences of Anemia
The purpose of the study was to determine what nutritional, demographic, and behavioral differences existed between children one year of age from two similar WIC clinics with different prevalences of anemia. Children from the higher-prevalence site were found to consume significantly (p < .05) more B12, C, copper, fiber, folate, total kilocalories, and riboflavin than did children from the lower-prevalence site. Family income and maternal weight gain were significantly (p < .05) higher in the lower-prevalence group as compared to the higher-prevalence group. In addition, children from the higher-prevalence site were enrolled in the WIC program at a significantly (p < .05) younger age than were children from the lower-prevalence site. digital.library.unt.edu/ark:/67531/metadc277976/
Nutritional Labeling on Menus in Full-Service Restaurants: Consumer Attitudes and Intended Usage
Access: Use of this item is restricted to the UNT Community.
Dining out has become an important part of the American lifestyle, greater frequencies as well as increased portion sizes have led to concern. The number of Americans that are classified as overweight or obese has also increased considerably, and the foodservice industry has become a target. Mandatory labeling of menu items has been avoided to this point, but the subject has moved to the forefront and continues to be debated. This study surveyed 502 patrons at a student-run restaurant in Texas. Respondents provided information concerning their health and dining habits as well as their attitudes toward and intended usage of nutritional information (NI) on menus in full-service restaurants. Gender, education levels, age, and household income affect the attitudes toward and intended usage of NI. Exercise frequency, the current use of nutritional information on packaged foods, and the practice of healthy eating habits are all related to the intended use of NI while dining out. digital.library.unt.edu/ark:/67531/metadc4813/

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/
An Observation System to Aid in the Evaluation and Implementation of Early Intervention Programs for Children with Autism
Early and intensive behavioral intervention outcome research includes descriptions of intervention variables that may increase treatment success. This study was designed to develop an observation system that incorporates and expands on some of these variables. Measures include the number of interventionist teaching units, types of skills addressed during instruction, consequences programmed by interventionists, and engagement with teaching materials. This system allowed for a view of the differences in teaching behaviors among the participants. It is proposed that this observation system is a start toward standardized intervention measures that can be applied to evaluate varied treatment models. Such standardization can help in ensuring that all children have access to evidence-based services. digital.library.unt.edu/ark:/67531/metadc9928/
An Observational Investigation of On-Duty Critical Care Nurses' Information Behavior in a Nonteaching Community Hospital
Critical care nurses work in an environment rich in informative interactions. Although there have been post hoc self-report survey studies of nurses' information seeking, there have been no observational studies of the patterns and content of their on-duty information behavior. This study used participant observation and in-context interviews to describe 50 hours of the observable information behavior of a representative sample of critical care nurses in a 20-bed critical care hospital unit. The researcher used open, in vivo, and axial coding to develop a grounded theory model of their consistent pattern of multimedia interactions. The resulting Nurse's Patient-Chart Cycle describes nurses' activities during the shift as centering on a regular alternation with the patient and the patient's chart (various record systems), clearly bounded with nursing "report" interactions at the beginning and the end of the shift. The nurses' demeanor markedly changed between interactions with the chart and interactions with the patient. Other informative interactions were observed with other health care workers and the patient's family, friends and visitors. The nurses' information seeking was centered on the patient. They mostly sought information from people, the patient record and other digital systems. They acted on or passed on most of the information they found. Some information they recorded for their personal use during the shift. The researcher observed the nurses using mostly patient specific information, but they also used some social and logistic information. They occasionally sought knowledge based information. Barriers to information acquisition included illegible handwriting, difficult navigation of online systems, equipment failure, unavailable people, social protocols and mistakes caused by multi-tasking people working with multiple complex systems. No formal use was observed of standardized nursing diagnoses, nursing interventions, or nursing outcomes taxonomies. While the nurses expressed respect for evidence-based practice, there clearly was no time or opportunity for reading research literature (either on paper or online) while on duty. All participants expressed frustration with the amount of redundant data entry required of them. The results of this study have significant implications for the design of clinical information systems and library services for working critical care nurses. digital.library.unt.edu/ark:/67531/metadc4498/

Observed Eye Contact between Selected Students and Teacher in the Music Making Process
High school band members (N=13) and their teacher were observed during six rehearsals of two contrasting band compositions over a six-week period. The contrasting compositions were selected by means of a detailed process between me (the researcher) and the teacher (the conductor). One 60-second excerpt of each composition was selected, during the performance of which, the students were observed. Three video tapings of each composition was done in order to capture occasions when the students would look up from their music. Using a technique adapted from Ekman (1997), the band members and teacher were then interviewed in order to reveal the reasons they recalled for looking up from their music. The results showed that the band members looked up in places where the teacher expected eye contact, that the frequency of eye contact changed little from one rehearsal to the next, and that the frequency of eye contact changed little between the two contrasting compositions. In all cases, the band members were able to recall the reasons for looking up from their music, a fact which led to a detailed analysis about the students' own thoughts while they were engaged in playing as an ensemble. The results are discussed in terms of strategies for teaching practice and implications for future research. digital.library.unt.edu/ark:/67531/metadc5380/
Observing and Attending in a Delayed Matching-to-Sample Preparation in Pigeons
Pigeons worked in a titrating delay match-to-sample (TDMTS) procedure in which selecting the correct comparison stimulus increased the delay between sample offset and comparison-array onset and incorrect comparison selections decreased that delay. Prior research in our lab has shown that the stable adjusted value of the retention interval is a curvilinear function of the observing response requirement. The current study examined the effect of the distribution and predictability of observing response requirements on adjusted retention interval values. The data show that unpredictable observing response requirements were more effective in attenuating the deleterious effects of delay on matching accuracy. The data have implications for our understanding of attending and encoding in performances involving remembering over short temporal durations. digital.library.unt.edu/ark:/67531/metadc9758/

Occlusion Tolerant Object Recognition Methods for Video Surveillance and Tracking of Moving Civilian Vehicles
Recently, there is a great interest in moving object tracking in the fields of security and surveillance. Object recognition under partial occlusion is the core of any object tracking system. This thesis presents an automatic and real-time color object-recognition system which is not only robust but also occlusion tolerant. The intended use of the system is to recognize and track external vehicles entered inside a secured area like a school campus or any army base. Statistical morphological skeleton is used to represent the visible shape of the vehicle. Simple curve matching and different feature based matching techniques are used to recognize the segmented vehicle. Features of the vehicle are extracted upon entering the secured area. The vehicle is recognized from either a digital video frame or a static digital image when needed. The recognition engine will help the design of a high performance tracking system meant for remote video surveillance. digital.library.unt.edu/ark:/67531/metadc5133/

The Occupational Aspirations and Expectations of Students Majoring In Jazz Studies At The University Of North Texas
The purpose of this study was to identify the occupational aspirations and expectations of students majoring in jazz studies, and to investigate relationships between students' aspirations, expectations and selected variables including significant others, choice of school, instrument type, academic achievement, academic level, socioeconomic status, age, gender, and early jazz experience. All jazz studies majors enrolled at the University of North Texas during the Spring 2001 academic semester responded to a pilot test questionnaire (return rate 85%, N = 211). Frequencies, percentages, means, and standard deviations described the students' occupational aspirations, occupational expectations, backgrounds and training in jazz prior to entering UNT, and determined the extent to which parents, relatives, teachers, friends, and role models helped steer them into jazz (Pearson r, Spearman Rho and Point Biserial correlation coefficients provided). The low to moderate positive correlation between aspirations and expectations (r = 0.43) indicated that the two variables were different and measured different types of occupations. Fifty percent of students aspired to be jazz performers whereas 29.7% expected to be jazz performers. While 42% aspired to be engaged in a combination of occupational activities, 48% expected a combination of occupational activities. Only 4.7% aspired to teach; however, almost 16% expected to be engaged in teaching. Low positive correlations were found between aspirations and significant others, expectations and significant others, expectations and gender, and expectations and role models. Respondents indicated that role models (jazz musicians, community musicians, and college instructors) had contributed the most to their decision to major in jazz. Recommendations for educators, researchers, and improvements to the questionnaire are provided. digital.library.unt.edu/ark:/67531/metadc5810/

Occupational therapy academic program faculty attitudes toward tenure as measured by the Tenure Attitude Scale
This study explored attitudes of occupational therapy faculty toward tenure and selected alternatives to tenure. A survey method was employed, and the Tenure Attitude Survey Instrument, (TASI), was created for use in the study. Additionally, a questionnaire sought information regarding respondents' rank, tenure and administrative status, institutional type, and years in academia. Participants were accredited occupational therapy professional program faculty who identified their primary work setting as "Academic" on the 2000-2001 American Occupational Therapy Association membership survey. Factor analysis of 577 surveys examined the structure of scores on the TASI, and the instrument consisted of 4 scales, and 18 items, as follows: Scale One: Attitude toward academic freedom and job security protection, 7 items; Scale Two: Attitude toward tenure in general, 6 items; Scale Three: Attitude toward stop-the-tenure clock provisions, 2 items; and Scale Four: Attitude toward post-tenure review, 3 items. Cronbach's alpha was conducted, as follows: TASI overall alpha = .7915; Scale 1 alpha = .7884; Scale 2 alpha = .8420; Scale 3 alpha = .7020; Scale 4 alpha = .4229. Proportional analysis showed that most respondents were full time faculty (88.1%); taught full time at public institutions (52.8%); were tenured or tenure-track (55.5%); had no administrative duties (70.5%); with a rank of instructor or lecturer (17.5%), or assistant professor (45.7%). Time in academia ranged from 1-40 years, with a mean of 11.27 years, median of 9.25 years, and mode of 4 years. Attitudes toward, and support for, the continuation of tenure and for selected proposed alternatives to tenure were analyzed according to the following: faculty rank, administrative status, and tenure status. Respondents held generally favorable attitudes toward tenure as measured by Scales 1 and 2 of the TASI, and the best predictors of faculty attitude toward tenure were tenure status and rank. Due to low reliability scores on Scales 3 and 4, no conclusions can be drawn regarding respondents' attitudes toward alternatives to tenure. digital.library.unt.edu/ark:/67531/metadc3265/

Ocean Biogeochemistry and Global Change
From the perspective of terrestrial ecosystems, the most important component of global change over the next three or four decades will likely be land-use/cover change. It is driven largely by the need to feed the expanding human population, expected to increase by almost one billion (109) people per decade for the next three decades at least. Much of this increase will occur in developing countries in the low-latitude regions of the world. To meet the associated food demand, crop yields will need to increase, consistently, by over 2% every year through this period. Despite advances in technology, increasing food production must lead to intensification of agriculture in areas which are already cropped, and conversion of forests and grasslands into cropping systems. Much of the latter will occur in semi-arid regions and on lands which are marginally suitable for cultivation, increasing the risk of soil erosion, accelerated water use, and further land degradation. digital.library.unt.edu/ark:/67531/metadc12039/
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/
Octatonic pitch structure and motivic organization in George Walker's Canvas for wind ensemble, voices, and chorus.
Canvas was commissioned by the College Band Directors National Association (CBDNA) Consortium in fall 1999 for the CBDNA Biennium National Conference to be held at the University of North Texas in February 2001. This substantial and profound three-movement work is Pulitzer Prize winning composer George Walker's first work for wind ensemble and is a milestone in wind composition at the turn of the millennium. This analysis considers Walker's sophisticated use of octatonic collections and their subsets. Walker uses the three transpositions of the octatonic scale as a harmonic framework for the work. Within this framework, specific subsets of the collection are used in traditional harmonic ways. A hierarchy of pitch sets is created, lending a "tonic" function characteristic to prevalent and specifically placed sonorities. Onto this "canvas" of octatonic harmonies, Walker "paints" specific motivic gestures. These motivic gesture monopolize specific intervallic relationships that are initially presented in the beginning of the work. Certain motivic techniques are then employed in the ongoing development of the motivic content. These motivic techniques include melodic suspension, interval alternation, double stroke articulation, irregularly recurring patterns, chordal punctuations, interrupted sequences, and dramatic uses of silence.

Officer attitudes toward organizational change in the Turkish National Police.
This dissertation emphasizes the importance of the human factor in the organizational change process. Change - the only constant - is inevitable for organizations and no change program can be achieved without the support and acceptance of organization members. In this context, this study identifies officer attitudes toward organizational change in the Turkish National Police (TNP) and the factors affecting those attitudes. The Officer Attitude Model created by the researcher includes six main factors (receptivity to change, readiness for change, trust in management, commitment to organization, communication of change, and training for change) and five background factors (gender, age, rank, level of education, and work experience) to explain officer attitudes toward change. In order to test this model, an officer attitude survey was administered in Turkey among TNP members and the results of the gathered data validated this model. digital.library.unt.edu/ark:/67531/metadc3977/
