Neuronal Network Analyses in vitro of Acute Individual and Combined Responses to Fluoxetine and Ethanol
Embryonic murine neuronal networks cultured on microelectrode arrays were used to quantify acute electrophysiological effects of fluoxetine and ethanol. Spontaneously active frontal cortex cultures showed highly repeatable, dose-dependent sensitivities to both compounds. Cultures began to respond to fluoxetine at 3 µM and were shut off at 10-16 µM. EC50s mean ± S.D. for spike and burst rates were 4.1 ± 1.5 µM and 4.5 ± 1.1 µM (n=14). The fluoxetine inhibition was reversible and without effect on action potential wave shapes. Ethanol showed initial inhibition at 20 mM, with spike and burst rate EC50s at 52.0 ± 17.4 mM and 56.0 ± 17.0 mM (n=15). Ethanol concentrations above 100 -140 mM led to cessation of activity. Although ethanol did not change the shape and amplitude of action potentials, unit specific effects were found. The combined application of ethanol and fluoxetine was additive. Ethanol did not potentiate the effect of fluoxetine. digital.library.unt.edu/ark:/67531/metadc3191/
Neuropsychologic correlates of a normal EEG variant: The mu rhythm.
Although the mu rhythm is traditionally defined as a normal EEG variant, recent evidence suggests that mu may have functional significance in a variety of disorders such as autism, Parkinson's disease, and multiple sclerosis. While an increasing number of articles have focused on the blocking mechanism of mu in relation to various cognitive processes and disorders, few have examined the significance of a prominent mu rhythm in the background EEG. A few studies have examined the relationship between the mu rhythm and psychological disturbance, such as attentional and affective disorders. Increasing evidence suggests that EEG and qEEG variables may be useful in classifying psychiatric disorders, presenting a neurophysiological alternative to traditional symptom-based diagnosis and classification. Thus, the intention of the present study was to examine the relationship between neuropsychological variables, gathered from multiple assessment sources, and the presence of a prominent mu rhythm in the EEG. Results did not show a statistically significant difference between individuals with and without a prominent mu rhythm on the Test of Variables of Attention (TOVA); although individuals in the mu group showed a pattern of increased impulsivity and performance decrement over time. For adults, no significant differences were observed between groups on psychological variables measured by the Minnesota Multiphasic Personality Inventory-2 (MMPI-2). However, for children, the mu and control groups differed on several behavioral and emotional variables on the Child Behavior Checklist (CBCL). Results are examined in the context of other research and clinical implications are discussed. digital.library.unt.edu/ark:/67531/metadc9032/
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/
Neuropsychological Functioning in Non-Schizophrenic First-Degree Relatives of Schizophrenics
Research has consistently shown schizophrenics to perform significantly poorer than normal controls on commonly used measures of neuropsychological functioning. Research on the neuropsychological functioning of first-degree relatives of schizophrenics who do not themselves have schizophrenia is comparatively sparse but suggests the likelihood of deficits in this group as well. A battery of standard neuropsychological tests was administered to three groups: first-degree relatives of schizophrenics who do not themselves have schizophrenia (FDR-SCZ), first-degree relatives of persons with major depression and bipolar disorder (FDR-MOOD), and normal controls (NC). The FDRSCZ group was not found to demonstrate significantly impaired performance relative to the other two groups on any of the hypothesized or exploratory analyses. These implications of these findings are discussed with reference to previous studies and future research. digital.library.unt.edu/ark:/67531/metadc278259/
Neuropsychological Predictors of Incompetency to Stand Trial
This study investigated the effect of cognitive factors on competency to stand trial. Previous researchers have investigated how psychological variables --such as psychosis and intelligence--contribute to incompetency. Although several researchers have established that intelligence contributes to incompetency, very few have investigated the role of specific cognitive abilities within the realm of intelligence. This study investigated the performance of 55 defendants referred for competency restoration on neuropsychological measures. Specifically, competent defendants and incompetent defendants were compared on several measures assessing functioning in seven cognitive domains. Competent defendants performed significantly better than incompetent defendants on measures of verbal comprehension, social judgment, verbal memory, and executive functioning. Competent and incompetent defendants did not differ on attention, visual spatial skills, or nonverbal memory. digital.library.unt.edu/ark:/67531/metadc4705/
Neuroticism and Religious Coping Styles as Mediators of Depressive Affect and Perceived Stress
Previous researchers have shown that the collaborative, self-directing, and deferring styles of religious coping result in different outcomes of depression under different levels of perceived stress. Neuroticism has also been shown to affect coping effectiveness overall or choice of coping method. However, little work has been done to investigate the association between neuroticism and the choice or effectiveness of religious coping styles in particular, or on the association of neuroticism and perceived stress. The present study addressed research questions by examining relations among neuroticism, perceived stress, objective life events, religious and non-religious coping styles, effectiveness of coping styles, and depression. Hierarchical multiple regression and correlational techniques found that religious coping styles predict depression, religious and non-religious coping correspond, and neuroticism predicts perceived stress beyond situational stressors. Neuroticism did not predict use of religious coping styles, but remaining personality factors were successful in predicting coping. Implications, limitations, and future directions are discussed. digital.library.unt.edu/ark:/67531/metadc4889/
Neutron Density Depression Due to an Oblate Spheroidal Detector
In this paper, two projects have been undertaken. First, Workman's calculations have been checked to a higher degree of approximation to determine the accuracy of his method. Second, a new set of boundary conditions has been developed for obtaining solutions of the neutron diffusion equation which do not depend on the solution of the equation inside the detector. digital.library.unt.edu/ark:/67531/metadc130362/
Neutron Transmutation and Hydrogenation Study of Hg₁₋xCdxTe
Anomalous Hall behavior of HgCdTe refers to a "double cross-over" feature of the Hall coefficient in p-type material, or a peak in the Hall mobility or Hall coefficient in n-type material. A magnetoconductivity tensor approach was utilized to identify presence of two electrons contributing to the conduction as well as transport properties of each electron in the material. The two electron model for the mobility shows that the anomalous Hall behavior results from the competition of two electrons, one in the energy gap graded region near the CdZnTe/HgCdTe interface with large band gap and the other in the bulk of the LPE film with narrow band gap. Hg0.78Cd0.22Te samples grown by LPE on CdZnTe(111B)-oriented substrates were exposed to various doses of thermal neutrons (~1.7 x 1016 - 1.25 x 1017 /cm2) and subsequently annealed at ~220oC for ~24h in Hg saturated vapor to recover damage and reduce the presence of Hg vacancies. Extensive Magnetotransport measurements were performed on these samples. SIMS profile for impurities produced by neutron irradiation was also obtained. The purpose for this study is to investigate the influence of neutron irradiation on this material as a basis for further study on HgCdTe74Se. The result shows that total mobility is observed to decrease with increased neutron dose and can be fitted by including a mobility inverse proportional to neutron dose. Electron introduction rate of thermal neutron is much smaller than that of fission neutrons. Total recovering of the material is suggested to have longer time annealing. Using Kane's model, we also fitted carrier concentration change at low temperature by introducing a donor level with activation energy changing with temperature. Results on Se diffusion in liquid phase epitaxy (LPE) grown HgCdTe epilayers is reported. The LPE Hg0.78Cd0.22Te samples were implanted with Se of 2.0×1014/cm2 at 100keV and annealed at 350-450oC in mercury saturated vapor. Secondary ions mass spectrometry (SIMS) profiles were obtained for each sample. From a Gaussian fit we find that the Se diffusion coefficient DSe is about one to two orders of magnitude smaller than that of arsenic. The as-implanted Se distribution is taken into account in case of small diffusion length in Gaussian fitting. Assuming a Te vacancy based mechanism, the Arrhenius relationship yields an activation energy 1.84eV. Dislocations introduced in HgCdTe materials result in two energy levels, where one is a donor and one is an acceptor. Hydrogenation treatment can effectively neutralize these dislocation defect levels. Both experimental results and theoretical calculation show that the mobility due to dislocation scattering remains constant in the low temperature range (<77K), and increases with temperature between 77K and 150K. Dislocation scattering has little effect on electrical transport properties of HgCdTe with an EPD lower than 107/cm2. Dislocations may have little effect on carrier concentration for semiconductor material with zinc blende structure due to self compensation. digital.library.unt.edu/ark:/67531/metadc9126/
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/

New Adventures in the Chemistry of Polycarboncyclic Ring Systems
I. Diels-Alder reactions of 1,2,3,4,9,9-hexachloro-1,4,4a,8a-tetrahydro-1,4-metha- nonaphthalene (16) and 1,2,3,4,9,9-hexachloro-1,4,6,7-tetrahydro-1,4-methanonaphthalene (17) toward dienophiles N-methyl-1,2,4-triazoline-3,5-dione (MTAD), N-phenyl-1,2,4-triazoline-3,5-dione (PTAD) and/or N-methylmaleimide (NMM) have been examined. II. Epoxides derived from functionalized 1,4,4a,9a-tetrahydro-9,10-dioxo-1,4-methanoanthracenes (1a and 1b) undergo acid- and base-promoted intramolecular nucleophilic ring-opening to form new polycyclic alcohols.

This species could be trapped in situ by cyclohexene, thereby affording the corresponding cycloadduct 46a and 46b. digital.library.unt.edu/ark:/67531/metadc278356/
A New Algorithm for Finding the Minimum Distance between Two Convex Hulls
The problem of computing the minimum distance between two convex hulls has applications to many areas including robotics, computer graphics and path planning. Moreover, determining the minimum distance between two convex hulls plays a significant role in support vector machines (SVM). In this study, a new algorithm for finding the minimum distance between two convex hulls is proposed and investigated. A convergence of the algorithm is proved and applicability of the algorithm to support vector machines is demostrated. The performance of the new algorithm is compared with the performance of one of the most popular algorithms, the sequential minimal optimization (SMO) method. The new algorithm is simple to understand, easy to implement, and can be more efficient than the SMO method for many SVM problems. digital.library.unt.edu/ark:/67531/metadc9845/
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 Approach to Measurement of Partial Knowledge
The problem of this study is that of developing a testing procedure for multiple-choice tests which would increase the relationship between test scores and a criterion. The procedure investigated in this research was one in which subjects took a multiple-choice test but were required to continue responding on each item until the correct answer was obtained. The total number of responses was used as the score on the test. The purpose of this research was to investigate the possibility of increasing predictability by changing the procedure of administering the test, rather than changing the test itself. digital.library.unt.edu/ark:/67531/metadc164087/

A New Approach to Texas Groundwater Management: An Environmental Justice Argument to Challenge the Rule of Capture
Texas is the last remaining state to utilize the rule of capture, a doctrine based on English Common Law, as a means of regulating groundwater resources. Many of the western states originally used the rule of capture to regulate their groundwater resources, but over time, each of these states replaced the rule of capture with other groundwater laws and regulations. The Texas Water Development Board (TWDB) State Water Plan, Water for Texas-2002, warned Texans if current water usage and laws do not change, there will be an unmet need of 7.5 million acre-feet of water annually by 2050. This caused individuals in state and local government to begin asking the question, "How are we going to meet our future water needs?" In the search for a solution to the water shortage problem people have divided themselves into two groups: one wants to consider the implementation of water conservation measures to reduce per capita water use in order to meet future demands; while the other group wants to spend millions of dollars to build reservoirs and dams along with laying thousands of miles of pipeline to move water around the state. The fact that Texas has yet to come up with a definitive answer to their water shortage peaked my curiosity to research what caused the State of Texas to get to a point of having a shortage of fresh water and then look at possible solutions that incorporate water conservation measures. In my thesis I present a historical overview of the rule of capture as Texas's means of groundwater management in order to illustrate the role it played in contributing to the water shortage Texans now face. I also take a historical look at the environmental justice movement, a grass-roots movement by environmentalists and Civil Rights activists working together to guarantee the rights of low-income and minority communities to clean and healthy environments, focusing on several acts and policies enacted by the federal government as a direct result of this movement. I then demonstrate how the rule of capture is in conflict with these acts and policies along with being in violation of both state and federal regulations in an attempt to establish a sound argument as to why we need to replace the rule of capture not only from an environmental standpoint, but from a legal standpoint as well. After considering groundwater legislation in other states, I offer a possible alternative to the rule of capture as part of the solution to the approaching shortage of Texas's fresh water supply. The implementation of new laws, regulations and conservation measures will help conserve water for future Texans, but we must also consider a change in our relationship to water along with the attitudes and ideas that resulted in a water shortage not only in Texas, but on a global scale if we truly want to solve our future water crisis. digital.library.unt.edu/ark:/67531/metadc4941/
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/

The New Emergence of the Spirit : A Study of Content and Style in Hegel and George Eliot
Hegel and Eliot have been chosen for this study not because of their differences but because of similarities in their thought. Although most of Hegel's works are obscure and pedantic, it is possible to show that his early thinking reflects a deep awareness of many of the implications of the new age. A growing number of philosophers and theologians today are apparently "rediscovering" Hegel as one who caught a vision of the transition in man's history and whose insights are valuable today. digital.library.unt.edu/ark:/67531/metadc131285/
A New Framework for Classification and Comparative Study of Congestion Control Schemes of ATM Networks
In our work, we have proposed a new framework for the classification and comparative study of ATM congestion control schemes. The different aspects on which we have classified the algorithms are control theoretic approach, action and congestion notification. These three aspects present of the classification present a coherent framework on which congestion control algorithms are to be classified. Such a classification will also help in developing new algorithms. digital.library.unt.edu/ark:/67531/metadc279372/
A New Gravitational Approach to Least Transportation Cost Warehouse Location
The purpose of this study is to examine single facility warehouse location models. The need for such a study is primarily two-fold. First, single facility warehouse location models which determine an alleged optimum location through a coordinate system have been developed. Secondly, the need for additional research is necessary because the approaches involving linear programming, simulation, or heuristic programming do not by definition generate an optimal location. digital.library.unt.edu/ark:/67531/metadc164418/
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/

A New N-way Reconfigurable Data Cache Architecture for Embedded Systems
Access: Use of this item is restricted to the UNT Community.
Performance and power consumption are most important issues while designing embedded systems. Several studies have shown that cache memory consumes about 50% of the total power in these systems. Thus, the architecture of the cache governs both performance and power usage of embedded systems. A new N-way reconfigurable data cache is proposed especially for embedded systems. This thesis explores the issues and design considerations involved in designing a reconfigurable cache. The proposed reconfigurable data cache architecture can be configured as direct-mapped, two-way, or four-way set associative using a mode selector. The module has been designed and simulated in Xilinx ISE 9.1i and ModelSim SE 6.3e using the Verilog hardware description language. digital.library.unt.edu/ark:/67531/metadc12079/
New Organized Crime: Problems and Issues for Information Analysis
This study illustrates the changing nature of organized crime at both national and international levels. Organized crime groups have changed in that they have entered the realm of high technology. In response this change, the use of new or modified analytical tools is suggested to enhance law enforcement efforts. This study highlights the problems of, and offers particular solutions for information analysis in its use in the fight against organized crime. Ultimately, it is argued that combined crime and intelligence analysis can be an effective and efficient method for the detection and prevention of modern organized crime. digital.library.unt.edu/ark:/67531/metadc2907/
New Reality Resembles Old: An Examination of the American Public's Social Construction of Reality Following September 11, 2001 Terrorist Attacks
This thesis examines whether the September 11, 2001 terrorist attacks caused a significant, lasting change in the American public's social construction of reality. A framework of everyday reality was created which focused on beliefs, behaviors, and cultural institutions in the United States. Data regarding specific beliefs and behaviors was collected from numerous survey sources, and content analysis was performed on media literature from September 11, 2001 to September 11, 2003. Findings from this study show that beliefs examined did change, while behaviors on similar topics did not. These finding represents an interesting paradox to be evaluated in future studies. Cultural institutions, as related to the public's knowledge of and relationship with each, also appeared little changed. Therefore, while some aspects displayed adjustment, this study cannot conclusively state that American public's social construction of reality experienced a "new reality" paradigm shift as proclaimed by the media immediately following the attacks. digital.library.unt.edu/ark:/67531/metadc4481/
New Resources in Twentieth-Century Piano Music and Richard Wilson's Eclogue (1974)
This dissertation draws some of the innovative composers from the early 1900's to the 1960's into the spotlight to highlight their new musical and pianistic ideas. These composers, including Debussy, Schoenberg, Webern, Bartók, Cowell and others, brought new creative forces into piano music, generating many distinctive features of modern music. The discussion of new resources in harmonic language, timbre, texture, form and concept of time has a direct bearing on aspects of Richard Wilson's Eclogue itself as well as aspects of performance problems. American Composer, Richard Wilson, has written three substantial piano solo works, Eclogue, Fixations, and Intercalations. Eclogue, from 1974, is a one-movement work. The detailed analysis of Eclogue covers aspects of form, harmonic language, timbre and texture, and rhythm and time. In addition, essential issues of performance problems such as notation, rhythmic control, extended techniques, hands distribution, and pedaling are also discussed. digital.library.unt.edu/ark:/67531/metadc2632/

New Shades of Clown White: a Study of Selected Comic Pantomimists in Europe and America 1920-1970
This thesis is neither a textbook of pantomime, with instructions for the development of mimetic expertise, nor a history of pantomime. What is recorded here is the personal philosophy of the art of pantomime advanced by Jean-Louis Barrault, Étienne Decroux, Charlie Chaplin, Marcel Marceau, and Red Skelton. The section devoted to each artist contains the portions of his biography pertaining to his development as a mime and a representative sample of critical reactions to his work. In addition to this purpose, this thesis also offers evidence that the comic style of pantomime underwent a change in nature in its use by the mimes who are studied here. Whereas the comic style was original! y unique to pantomimes that had no other intent but to produce laughter or, at most, pathos by physical comedy, these mimes took the comic pantomime into the realms of introspection and philosophy. digital.library.unt.edu/ark:/67531/metadc164020/
New Surveillance Technologies and the Invasion of Privacy Rights
Access: Use of this item is restricted to the UNT Community.
Definition of privacy has changed by the changes and improvements in information and surveillance technologies. These changes and improvement need new legal decisions for new kinds of privacy invasions. This study explores the scope of privacy right, particularly when a technological surveillance has occurred by law enforcement agencies. It focuses in particular on increasing law enforcements' surveillance technologies and devices that have the potential to impact citizens' information privacy. These increasing changes in surveillance technologies have important implications both for law enforcements and citizens. This study also discusses increasing law enforcement surveillance for the public's security, changes of the laws that allow law enforcements to use new surveillance powers as a war on terrorism, and the citizens concerns of information privacy. A particular attention is given to the recent public opinion surveys which show citizens' increasing privacy concerns. Finally, a set of recommendations to figure out security-privacy debate and reduce the privacy concerns of the citizens is offered. digital.library.unt.edu/ark:/67531/metadc4252/
A New Wireless Sensor Node Design for Program Isolation and Power Flexibility
Over-the-air programming systems for wireless sensor networks have drawbacks that stem from fundamental limitations in the hardware used in current sensor nodes. Also, advances in technology make it feasible to use capacitors as the sole energy storage mechanism for sensor nodes using energy harvesting, but most current designs require additional electronics. These two considerations led to the design of a new sensor node. A microcontroller was chosen that meets the Popek and Goldberg virtualization requirements. The hardware design for this new sensor node is presented, as well as a preliminary operating system. The prototypes are tested, and demonstrated to be sustainable with a capacitor and solar panel. The issue of capacitor leakage is considered and measured. digital.library.unt.edu/ark:/67531/metadc28378/

This is the first known study to explore the image retrieval preferences of news photographers and news photo editors in work contexts. Survey participants (n=102) provided opinions regarding 11 photograph searching methods. The quantitative survey data were analyzed using descriptive statistics, while content analysis was used to evaluate the qualitative survey data. In addition, news photographers and news photo editors (n=11) participated in interviews. Data from the interviews were analyzed with phenomenography. The survey data demonstrated that most participants prefer searching by events taking place in the photograph, objects that exist in the photograph, photographer-provided keywords, and relevant metadata, such as the date the picture was taken. They also prefer browsing. Respondents had mixed opinions about searching by emotions elicited in a photograph, as well as the environmental conditions represented in a photograph. Participants' lowest-rated methods included color and light, lines and shapes, and depth, shadow, or perspective. They also expressed little interest in technical information about a photograph, such as shutter speed and aperture. Interview participants' opinions about the search methods reflected the survey respondents' views. They discussed other aspects of news photography as well, including the stories told by the pictures, technical concerns about digital photography, and digital archiving and preservation issues. These stated preferences for keyword searching, browsing, and photographer-provided keywords illustrate a desire for a strong internal locus of control in digital photograph archives. Such methods allow users more control over access to their photographs, while the methods deemed less favorable by survey participants offer less control. Participants believe they can best find their photographs if they can control how they index and search for them. Therefore, it would be useful to design online photograph archives that allow users to control representation and access. Future research possibilities include determining the preferences of other image retrieval system users, performing user studies with moving image information retrieval systems, and uniting content-based and concept-based image retrieval research. digital.library.unt.edu/ark:/67531/metadc5591/
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/
Nicotinic Acetylcholine Receptor α3 mRNA in Rat Visual System After Monocular Deprivation
In situ hybridization was used to examine effects of monocular enucleation on nicotinic acetylcholine receptor subunit cc3 mRNA in the rat dLGNand visual cortex. After 28 days postoperative, there were no significant differences in α3 mRNA density between the contralateral (deprived) and ipsilateral (non-deprived) sides. The lack of obvious effects of visual deprivation on α3 mRNA density suggests that other factors, possibly intrinsic to dLGNand visual cortex, govern the postnatal expression of α3 mRNA. digital.library.unt.edu/ark:/67531/metadc278900/
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/
Night of no Exile
Night of no Exile is a collection of poems preceded by a critical article entitled "‘Exile seems both a blessing and a curse': A Blissful Reading of Li-Young Lee's Poetry." That article discusses Lee's quest to achieve communication, truth, and transcendence through poetic language and concludes that he finally reaches his goal through a leap from narrative poetry to lyricism. The "exile" alluded to in the title of the article is not only geographic, but also interioran exile due to the natural limitations of all languages, and which can be bridged only in linguistic ways. Lee's solution to that problem (lyricism) turns his poetry into what Roland Barthes would call "a text of bliss," a text that manages to deeply destabilize language, while simultaneously achieving a new kind of meaning. In the main body of the manuscript, the first section contains short love lyrics. The second section, "Night of no Exile," is an attempt at the demanding genre of the longer lyric poem. The third section uses short lyrics to explore various topics, such as discovering one's identity, friendship and solidarity between women, family history, and childhood memories. Finally, the last section includes poems, four of them longer, attempting to combine narrative and lyric impulses in a way not unlike Li-Young Lee's experimentation with those two genres. digital.library.unt.edu/ark:/67531/metadc2217/
The Nightingale in Poetry and Music
Access: Use of this item is restricted to the UNT Community.
This thesis surveys a variety of songs and arias for high soprano which feature the nightingale; examines the musical elements that symbolize, refer to, or imitate the nightingale; and compares these musical elements with transcriptions of the nightingale's song. The first chapter reviews the symbolic development of the nightingale and its role in poetry and literature. The interior chapters address a selection of musical compositions that feature the nightingale and its song. The final chapter establishes a relationship between the sound of the actual sound of the nightingale and the musical gestures created by composers to imitate the nightingale. digital.library.unt.edu/ark:/67531/metadc4161/
The Nightingale's Flight from Opera to Symphonic Poem: A Comparative Study of The Nightingale and The Song of the Nightingale by Igor Stravinsky
An analysis of the transformation from Stravinsky's opera The Nightingale to The Song of the Nightingale, a symphonic poem by the same composer. The text includes a brief history of Stravinsky's life and the genesis of The Nightingale and The Song of the Nightingale. The bulk of the dissertation discusses actual changes employed by Stravinsky (with score examples). Patterns of modifications are identified and discussed as they relate to the composer's change of attitude in orchestration. The analysis focuses on overall patterns of alteration imposed by Stravinsky and their perceived effectiveness achieving a symphonic aural outcome. digital.library.unt.edu/ark:/67531/metadc2725/
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/

The Nineteenth Century Oboe Concertino: An Overview of its Structure with Two Performance Guides
Music written for oboe and orchestra in the nineteenth century falls into three categories: Classical Concerto, Opera Fantasy, and Concertino. The classical, or standard, three movement, sonata-ritornello format was only sparingly used. Instead, composers chose more the experimental forms of the Opera Fantasy and Concertino. The Opera Fantasy was used as a way for oboe players to play popular opera arias of the time, while showcasing their virtuosity and expression. It is in the Concertino where composers expanded the oboe repertoire to its highest form in the nineteenth century, experimenting with structure, and using the oboe to the height of its expressive powers. In addition to discussion on the Concertino in general, performance guides have been provided for two concertinos, Concertino for Oboe and Winds, by Carl Maria von Weber and Concertino for Oboe and Orchestra, Op. 18, by August Klughardt. Information is provided regarding composer biography, compositional/historical perspective, technical and stylistic considerations, and structure. By examining the two very different pieces, one from the beginning of the nineteenth century and one from the end, the evolution of the Concertino can be seen, as well as gaining an understanding of the wide variety of repertoire written for the oboe in the nineteenth century. digital.library.unt.edu/ark:/67531/metadc3225/
Ninth grade student success: An analysis of a credit recovery program.
The purpose of the study was to determine the extent to which a credit recovery program improved the academic success for high school freshmen. For the purpose of this study, academic success was defined as whether or not the student advanced from 9th to 10th grade. A total of 255 students from two junior high schools and one comprehensive high school were included in the study. Independent variables included program, gender, ethnicity, socioeconomic status, TAKS Reading/Language Arts results, and TAKS Mathematics results. A review of related literature provided background information regarding the issues surrounding high school freshmen, dropouts, grade retention, and effective intervention programs. This quantitative study utilized descriptive statistics and logistic regression to analyze the relationship between the independent variables and student success as measured by whether or not the student advanced from ninth to tenth grade. In addition, the study examined the odds of success if participating in the credit recovery program. Sources of data included Incomplete and Failure Listing, Ninth Grade Advisor Listing, Tenth Grade Advisory Listing, and the Student Roster-Fall Collection. The Ninth Grade Success Initiative Program Evaluation for Cycles 6, 7, and 9 provided the individual student results of participation in the program. Levels of significance were set at the .05 level. The findings of this study indicated that no statistically significant relationship existed between participation in the credit recovery program, gender, ethnicity, socioeconomic status, TAKS Reading/Language Arts results, TAKS Mathematics results, and advancing from 9th to 10th grade. It was concluded that further study would be needed to determine the most effective means for providing academic assistance to ninth grade students. digital.library.unt.edu/ark:/67531/metadc4431/
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/
Nitration of Thiophene Analogs of DDT
Since thiophene very often yields compounds that are analogous to benzene derivatives in general physiological properties, it was decided to attempt to prepare the nitro and amino derivatives of 1,1,1-trichloro-2,2-bis-(2-thienyl)-ethane (V) as well as the nitro and amino derivatives of 2,2,3-trichloro-1,1-bis-(2-thienyl)-butane (VI). digital.library.unt.edu/ark:/67531/metadc163827/
