Employer Attitude toward the Mentally Retarded - an Application of a Cognitive Theory of Attitude Structure
It was the purpose of this study to investigate some of the factors related to employers' attitudes toward the hiring of a mentally retarded individual. More specifically, an attempt was made to answer the question, "Why do employers hold favorable or unfavorable attitudes toward the hiring of the retarded?" digital.library.unt.edu/ark:/67531/metadc130765/
The Employment Act of 1946: Original Intent Versus Current Interpretation, The Forces Underlying the Modification and the Implications thereof
There appears to be a vacillation from the original intent of the Employment Act of 1946. It was originally intended to serve as a tool whereby the smoothing and the easing of cyclical fluctuations of the business cycle could be facilitated. It now seems as though this tool has become one which is being used to correct those structural weaknesses which exist in the economy. digital.library.unt.edu/ark:/67531/metadc130493/

Employment Interventions for Consumers with HIV/AIDS
A systematic review of studies pertaining to employment interventions for consumers with HIV/AIDS was conducted in order to ascertain what programs and services have resulted in employment for people in this population. Research shows that programs specifically designed for individuals with HIV/AIDS have been beneficial for this population in regards to obtaining employment. This study discusses four employment interventions for people with HIV/AIDS including participation rates and employment outcome for program participants. A review of literature pertaining to employment interventions for individuals with HIV/AIDS is presented. Additionally, the systematic review methodology and results are presented. Finally, I discuss the results, limitations in regards to conducting the study, current research and recommendations for future research. digital.library.unt.edu/ark:/67531/metadc103335/
Employment of dual frequency excitation method to improve the accuracy of an optical current sensor, by measuring both current and temperature.
Optical current sensors (OCSs) are initially developed to measure relatively large current over a wide range of frequency band. They are also used as protective devices in the event a fault occurs due to a short circuit, in the power generation and distribution industries. The basic principal used in OCS is the Faraday effect. When a light guiding faraday medium is placed in a magnetic field which is produced by the current flowing in the conductor around the magnetic core, the plane of polarization of the linearly polarized light is rotated. The angle of rotation is proportional to the magnetic field strength, proportionality constant and the interaction length. The proportionality constant is the Verdet constant V (λ, T), which is dependent on both temperature and wavelength of the light. Opto electrical methods are used to measure the angle of rotation of the polarization plane. By measuring the angle the current flowing in the current carrying conductor can be calculated. But the accuracy of the OCS is lost of the angle of rotation of the polarization plane is dependent on the Verdet constant, apart from the magnetic field strength. As temperature increases the Verdet constant decreases, so the angle of rotation decreases. To compensate the effect of temperature on the OCS, a new method has been proposed. The current and temperature are measured with the help of a duel frequency method. To detect the line current in the conductor or coil, a small signal from the line current is fed to the reference of the lock in. To detect the temperature, the coil is excited with an electrical signal of a frequency different from the line frequency, and a small sample of this frequency signal is applied to the reference of the lock in. The temperature and current readings obtained are look up at the database value to give the actual output. Controlled environment is maintained to record the values in the database that maps the current and temperature magnitude values at the DSP lock in amplifier, to the actual temperature and current. By this method we can achieve better compensation to the temperature changes, with a large dynamic range and better sensitivity and accuracy. digital.library.unt.edu/ark:/67531/metadc9766/
The employment of historically-informed performance practices in present-day tuba performances of two Italian baroque violoncello transcriptions.
As several Italian baroque violoncello transcriptions have entered the standard performance repertory for both high school and collegiate tubists, and as numerous texts, articles, and baroque performance instruction courses have illuminated a new realm of performance possibilities, no published document has provided specific, thorough, and sample approaches to performance on the tuba of a given piece (or pieces) through a detailed application of materials found in any singular source or combination of sources. Many of the existing articles and texts that approach the subject focus largely on ornamentation, while limiting the discussion and application of the following topics: tempo, spirit, affect, notation, rhythm, dynamics, and articulation. This document examines such topics and provides detailed explanations and suggestions of historically-informed characteristics applicable to two movements each from the R. Winston Morris transcription of Antonio Vivaldi's Sonata No. 3 in A Minor and the Donald C. Little/Richard B. Nelson transcription of Benedetto Marcello's Sonata No. V in C Major. digital.library.unt.edu/ark:/67531/metadc6122/
Employment of Older Persons as Foster Grandparents
This thesis is a report of a study of the employment of foster grandparents for the foster grandparent project at the Denton State School in Denton, Texas. There were three specific interests in the study. First, it attempted to ascertain what criteria were used for the hiring of foster grandparents and how they were hired. Included in this area were the necessary steps which an individual had to take to apply for employment. Second, the study was concerned with developing a general description of the social and economic characteristics of those who were hired as foster grandparents, including their performance on certain tests which they took during the employment process. Third, it examined the relationship of selected social and economic characteristics to each other, the inter-relationships of test performance, and the relationships between the selected characteristics and test performance. digital.library.unt.edu/ark:/67531/metadc699649/
Employment of the Rorschach Inkblot Test with the Devries Suicide Inventory
This investigation represents an attempt to employ the Devries Suicide Prediction Scale and the Rorschach Inkblot Test in a two-stage predictive model which was designed to decrease the high false positive rate associated with the Devries and to design a way in which the Rorschach could be used efficiently in suicide prediction in a large mental hospital setting. The Rorschach was not found to significantly improve the predictive ability of the Devries. An unexpectedly high percentage of mental patients in the study, thirty-eight percent, admitted to previous suicide attempts, raising the question of whether suicidal behavior is not more common than is usually thought. digital.library.unt.edu/ark:/67531/metadc504130/

Empowering Agent for Oklahoma School Learning Communities: An Examination of the Oklahoma Library Improvement Program
The purposes of this study were to determine the initial impact of the Oklahoma Library Media Improvement Grants on Oklahoma school library media programs; assess whether the Oklahoma Library Media Improvement Grants continue to contribute to Oklahoma school learning communities; and examine possible relationships between school library media programs and student academic success. It also seeks to document the history of the Oklahoma Library Media Improvement Program 1978 - 1994 and increase awareness of its influence upon the Oklahoma school library media programs. Methods of data collection included: examining Oklahoma Library Media Improvement Program archival materials; sending a survey to 1703 school principals in Oklahoma; and interviewing Oklahoma Library Media Improvement Program participants. Data collection took place over a one year period. Data analyses were conducted in three primary phases: descriptive statistics and frequencies were disaggregated to examine mean scores as they related to money spent on school library media programs; opinions of school library media programs; and possible relationships between school library media programs and student academic achievement. Analysis of variance was used in the second phase of data analysis to determine if any variation between means was significant as related to Oklahoma Library Improvement Grants, time spent in the library media center by library media specialists, principal gender, opinions of library media programs, student achievement indicators, and the region of the state in which the respondent was located. The third phase of data analysis compared longitudinal data collected in the 2000 survey with past data. The primary results indicated students in Oklahoma from schools with a centralized library media center, served by a full-time library media specialist, and the school having received one or more Library Media Improvement Grants scored significantly higher academically than students in schools not having a centralized library media center, not served by a full-time library media specialist, and the school not having received one or more Library Media Improvement Grants. Students in schools having even one of these components scored higher academically than students in schools with none of these components. digital.library.unt.edu/ark:/67531/metadc2637/

The Empyrean: The Pinnacle of the Medieval World View (Twelfth-Fourteenth Centuries
The heavenly empyrean was the highest expression of the Medieval Weltanschauung (world view). It served as the outermost sphere of the Aristotelian/Ptolemaic geocentric cosmos while possessing an eminent theological status. This paper explores the importance of the empyrean during the Scholastic Period (eleventh through fourteenth centuries). digital.library.unt.edu/ark:/67531/metadc277828/
Enacting Community Through the Arts
This study is concerned with the roles and relationships between artists-in-residence, community audiences, and program coordinators/art educators as they engage together in community arts programs. This study takes place at Project Row Houses (PRH), a community arts organization located in Houston, Texas and focuses on the artist-in-residence program, which commissions a group of national and international artists for a 6-month period to create art installations in relation to the community and its African-American heritage. This ethnographic case study is based on the activities and events surrounding the 2008 PRH exhibition, Round 29, Thunderbolt Special: The Great Electric Show and Dance, after Sam Lightnin’ Hopkins and employed qualitative data gathering methods of participant-observation, conducting semi-structured, open-ended, in-depth interviews, and through document collection, and contextual information. Observations were recorded through field notes, photographs, and video. Interviews were conducted with 3 artists-in-residence, 3 community audience members, and 3 program coordinators or staff members involved with the program, regarding their experiences at the site and experiences with each other. My analysis presents the roles of artist, community audience, and program coordinator/art educator through three sections on cultural work. Within these sections I discuss topics related to the power of voice, situatedness, and creativity, as it relates to the artists and community audiences. For the role of program coordinator/art educator, I focus more closely on her role in the process of mediation. Topics of power, social dynamics, identity, and representation are also framed within these discussions. digital.library.unt.edu/ark:/67531/metadc799525/
Enacting Racism: Clarence Thomas, George Bush, and the Construction of Social Reality
This study analyzes the confirmation hearings discourse of Clarence Thomas and George Bush. Language constructs social reality. The United States has a history of racism and this history manifests itself in our language. The discourse of Clarence Thomas and George Bush created a social reality that equated opposition to Thomas' confirmation with racism using rhetorical strategies that included metaphor and narrative construction. digital.library.unt.edu/ark:/67531/metadc278489/
The Enameling Arts in Kuwaiti Pre-service Art Teacher Education
Access: Use of this item is restricted to the UNT Community.
The purpose of this study was twofold: (1) to examine the knowledge, skills, and experiences in the enameling arts and the attitudes and perceptions of in-service (n = 12) and pre-service Kuwaiti art teachers (n = 170), art supervisors at the Ministry of Education (MOE) (n = 3) and art education faculty members at the College of Basic Education (CBE) and Kuwait University (KU) (n = 8) about what they believed pre-service art teachers should know and be able to do in order to teach the enameling arts, and (2) to use this information to inform and guide the development of a content outline for an enameling course for pre-service Kuwaiti art teachers that is educationally (how to perform enameling arts skills and how to teach what they know), practically (safety issues, workshop management, etc), and culturally (its relation to Islamic culture) suitable. Both quantitative and qualitative approaches were used. Most of the respondents revealed limited knowledge and skills and modest experiences in the enameling arts. All interviewees in the study expressed positive perceptions and attitudes about the enameling arts. Most agreed that a revision to the current art education curriculum at the CBE was needed and made suggestions about how the curriculum should be revised. It was clear that there is a disconnection and miscommunication between the MOE and the CBE with regards to the information about enameling that should be covered and taught in the art education classes. All respondents expressed support for the inclusion of a course in enameling in the art education curriculum at the CBE. Because of the limited knowledge of the participants in the study, they were not able to provide guidance in shaping the content for a course in the enameling arts. The researcher had to rely on the literature review and his expertise as an enameling artist to develop a content outline that was educationally, practically, and culturally suitable for the pre-service Kuwaiti art teachers. Further study was recommended in regard to curriculum issues, especially those related to the inclusion of Islamic culture, and methods of delivering instruction in the enameling arts. digital.library.unt.edu/ark:/67531/metadc28410/
Encoding Variability and Differential Negative Transfer and Retroactive Interference in Children
Second-graders were tested for negative transfer and retroactive interference using an A-B, A-D paradigm. Four-pair, word-number lists were aurally presented to the children. Subjects were classified as being whole-only encoders or multiple encoders by the use of a recall test presented after list one. Significant negative transfer and retroactive interference were found. The multiple encoders experiences less difficulty in learning the second list that did the whole-only encoders, but these two groups did no differ with regard to transfer or retroactive interference effects. The results were considered in the context of Martin's encoding variability hypothesis. digital.library.unt.edu/ark:/67531/metadc663178/
End of Insertion Detection in Colonoscopy Videos
Colorectal cancer is the second leading cause of cancer-related deaths behind lung cancer in the United States. Colonoscopy is the preferred screening method for detection of diseases like Colorectal Cancer. In the year 2006, American Society for Gastrointestinal Endoscopy (ASGE) and American College of Gastroenterology (ACG) issued guidelines for quality colonoscopy. The guidelines suggest that on average the withdrawal phase during a screening colonoscopy should last a minimum of 6 minutes. My aim is to classify the colonoscopy video into insertion and withdrawal phase. The problem is that currently existing shot detection techniques cannot be applied because colonoscopy is a single camera shot from start to end. An algorithm to detect phase boundary has already been developed by the MIGLAB team. Existing method has acceptable levels of accuracy but the main issue is dependency on MPEG (Moving Pictures Expert Group) 1/2. I implemented exhaustive search for motion estimation to reduce the execution time and improve the accuracy. I took advantages of the C/C++ programming languages with multithreading which helped us get even better performances in terms of execution time. I propose a method for improving the current method of colonoscopy video analysis and also an extension for the same to make it usable for real time videos. The real time version we implemented is capable of handling streams coming directly from the camera in the form of uncompressed bitmap frames. Existing implementation could not be applied to real time scenario because of its dependency on MPEG 1/2. Future direction of this research includes improved motion search and GPU parallel computing techniques. digital.library.unt.edu/ark:/67531/metadc12159/
End of Life Care: African Americans' Disproportionate Use of Hospice
The United States of America is a country composed of various ethnicities. This country is considered to be a multi-cultural society. There are various cultural traditions values, norms and superstitious practices within each ethnic group. Attitudes toward end of life care are complex and vary differently across each ethnic group. This study explored factors that explained African Americans' disproportionate use of hospice. Access to hospice care was address, experience with hospice was explored, and recommendations were provided. This study conducted non-experimental research. The design of this exploratory study was quantitative in nature. A survey approach was utilized to collect data that was statistically analyzed. The important concept was African American disproportionate use of hospice. The variable willingness to use was employed to try to explain African Americans' disproportionate use of hospice. The independent variables African Americans who mistrust formal healthcare providers and knowledge about hospice services were operationalized using multiple indicators. The independent variable experience with hospice services did not use a scale. The research findings supported all three study hypotheses. This research results recommend that an important focus of the future be to counsel persons on the availability of hospice as an option for end-of-life care. Well-structured programs of training in cultural awareness and cultural competence throughout the ranks of the health care system must be instituted. Such an effort will pay dividends in reducing cultural mistrust and push closer to eliminating health disparities between minority groups and the rest of society. digital.library.unt.edu/ark:/67531/metadc33185/
Endangered newspaper: An analysis of 10 years of corporate messages from the Dallas Morning News.
Most newspapers today are struggling to survive in an increasingly fragmented and digital media environment. How have their owners or corporate parents shaped or adapted their business practices to in order to thrive? This question guides the overall approach to this study. The focus is on one newspaper, the Dallas Morning News. In particular, how has the News used corporate messages to respond to the changing media landscape? This study employs forms of rhetorical and discourse analysis to determine the effectiveness of the News' corporate messages during a 10-year period in order to answer this question. This study finds that the News used inconsistent and ineffective corporate communications throughout this tumultuous period. digital.library.unt.edu/ark:/67531/metadc12162/
Endocannabinoid System in a Planarian Model
In this study, the presence and possible function of endocannabinoid ligands in the planarian is investigated. The endocannabinoids ananadamide (AEA) and 2-arachidonoylglycerol (2-AG) and entourage NAE compounds palmitoylethanolamide (PEA), stearoylethanolamide (SEA) and oleoylethanolamide (OEA) were found in Dugesia dorotocephala. Changes in SEA, PEA, and AEA levels were observed over the initial twelve hours of active regeneration. Exogenously applied AEA, 2-AG and their catabolic inhibition effected biphasic changes in locomotor velocity, analogous to those observed in murines. The genome of a close relative, Schmidtea mediterranea, courtesy of the University of Utah S. med genome database, was explored for cannabinoid receptors, none were found. A putative fatty acid amide hydrolase (FAAH) homolog was found in Schmidtea mediterranea. digital.library.unt.edu/ark:/67531/metadc33188/
Endocrine Disruption of Levonorgestrel in Early-life Stages of Fathead Minnows, Pimephales Promelas
Pharmaceuticals have routinely been detected in the environment resulting in a growing concern about whether these drugs could elicit effects on aquatic organisms. The concerns are centered on the highly conserved nature of mammalian therapeutic targets in fish. These pharmaceuticals are found at very low levels in the environment, which can result in sub-lethal effects in aquatic organisms. Therefore, 28 d early-life stage studies were conducted on six pharmaceuticals to assess their impacts on survival and growth fathead minnow larvae. Two pharmaceuticals tested, carbamazepine and fenofibrate, resulted in no alterations to survival and growth. However, amiodarone, clozapine, dexamethasone, and levonorgestrel (LNG) reduced survival at concentrations tested with LNG being the most potent at 462 ng/L. Survival was increased with amiodarone and clozapine; however LNG significantly decreased growth at 86 ng/L. Therefore, the most potent pharmaceutical tested was the synthetic progestin LNG with survival and growth impacts at concentrations less than 1 μg/L. Further analysis was conducted by measuring specific endocrine related mRNA transcript profiles in FHM larvae following the 28 d ELS exposure to LNG. Transcripts of 3β-HSD, 20β-HSD, and FSH were significantly down-regulated following 28 d exposure to both 16.3 and 86.9 ng/L LNG. Also, CYP19a expression was significantly down-regulated at 86.9 and 2392 ng/L LNG. Subsequently, a second study examined time periods that may be most sensitive (e.g., windows of sensitivity) for FHM larvae exposed to LNG. Larvae were exposed to a single concentration of LNG (i.e. LOECgrowth of 86.2 ng/L as determined in the 28 d ELS study) for different time periods starting with fertilized egg through 28 dph. Growth and mRNA expression of the four differentially expressed transcripts from the first study were measured. Regardless of the duration of exposure, LNG significantly decreased growth in fathead minnow larvae at day 28. For both 20β-HSD and CYP19a, mRNA expression was decreased following exposure to LNG; however, these transcripts returned to baseline levels after removal of LNG. 3β-HSD and FSH showed similar trends after exposure to LNG with 7-14 d and 14-28 d exposures exhibiting a decrease in expression; however, FSH expression returned to baseline once removed for LNG exposure. Based on these data, 3β-HSD was the only transcript to remain down regulated after LNG exposure. Together these data suggest LNG can negatively impact FHM larval survival and growth, with significant alterations in endocrine related responses. However, these changes in endocrine related responses may not directly correlate to the changes in growth demonstrated with LNG exposure to fathead minnows. Therefore, additional research is warranted to ascertain additional mechanisms, either endocrine related or non-endocrine functions, related to changes in growth of larval fathead minnows. digital.library.unt.edu/ark:/67531/metadc283848/
Endogenous Constructivist Implications for Methodology : Focus on Young Children with Developmental Delay in the Social and Emotional Domains
The Ecologically-Based Activity Plan (EBAP) is proposed as a method to create a transition between special education and general education. It serves as a tool to help classroom teachers assess the environment of the class and as a method for embedding instruction within the naturally occurring context of the endogenous constructivist classroom. In this study the EBAP was used to reduce aggressive behavior and increase prosocial behavior among five children who displayed developmental delays in the social and emotional domains. digital.library.unt.edu/ark:/67531/metadc279375/
Endogenous Information and Inter-state War Expansion
Scholars have long debated the causes of late third party state joining in ongoing inter-state wars. This research has generally concluding that peace-time conditions, measured in terms of: third party capabilities; proximity to warring states; and inter-state alliances, are determining factors in the decision to join. However, these studies utilize theories derived from static pre-war measures of capabilities and motivation to explain late joining; indeed, the same measures that fail to predict participation at war's outset. Further, extant research has no explanation for why weak and non-proximate states every participate. Existing theory thus fails to provide a comprehensive explanation of joining behavior. This project contends that a resolution lies the interaction between pre-war conditions and intra-war events. Intra-war events that are allowed to vary on a per battle basis, including change in combat location and alliance entry and exit from combat, reveal new information about the war and its progress, thereby forcing third party states to recalculate their initial decision to abstain in relation to their pre-existing situation. Incorporation of intra-war processes helps to better explain decisions by third party states to join ongoing inter-state wars late in their development, and why states that frequently choose to abstain (e.g., weak states) ever choose to participate. This project is executed using a combination of ex post facto historical case studies, a theory of joining based on pre and intra-war environments, and large-N empirical analysis on all inter-state wars 1823-1988, conducted utilizing a novel collection of event-level data based on inter-state war battles. digital.library.unt.edu/ark:/67531/metadc177227/

Endogenous Nucleotide Pools in Growing Cells of Azotobacter Vinelandii
The objective of this investigation was to examine the changes in the nucleotide pools of Azotobacter vinelandii during the growth cycle. Endogenous ribonucleotides were extracted from A. vinelandii using trichloroacetic acid (TCA; 12% w/v). The 5' mono-, di- and triphosphates of adenine, guanine, uracil and cytosine were separated and quantified by anion-exchange high performance liquid chromatography. Results indicated that the adenylate energy charge of A. vinelandii paralleled the growth rate during exponential phase and that it declined rapidly as the stationary phase was reached. In addition, the amount of each nucleotide in A. vinelandii tended to increase in the logarithmic phase and decrease in the stationary phase in a similar manner to the energy charge. digital.library.unt.edu/ark:/67531/metadc500771/
The Enemy of My Enemy: International Alliances Against Transnational Terrorist Organizations
A dearth of pre-existing research in the field prompted this thesis on whether traditional econometric analyses of war deterrent alliances are applicable to modern alliances for counter terror purposes. Apparent foundational and contextual differences between the two types of alliances and the costs and benefits member nations derive from each lead the author to theorize that factors contributing to the formation of each alliance are fundamentally similar. Multiple types of statistical models are used to measure variables from the Correlates of War and Polity datasets combined with custom variables in a new dataset concerning major transnational terrorist attacks and the resultant alliances in testing the effect of traditionally contributing formation factors on alliances against terrorism. The results indicate that some contributing factors are similar, extant analysis tools have utility and that further investigation is justified. digital.library.unt.edu/ark:/67531/metadc33135/
The Enemy of My Enemy Is What, Exactly? the British Flanders Expedition of 1793 and Coalition Diplomacy
Access: Use of this item is restricted to the UNT Community.
The British entered the War of the First Coalition against Revolutionary France in 1793 diplomatically isolated and militarily unprepared for a major war. Nonetheless, a French attack on the Dutch Republic in February 1793 forced the British to dispatch a small expeditionary force to defend their ally. Throughout the Flanders campaign of 1793, the British expeditionary force served London as a tool to end British isolation and enlist Austrian commitment to securing British war objectives. The 1793 Flanders campaign and the Allied war effort in general have received little attention from historians, and they generally receive dismissive condemnation in general histories of the French Revolutionary Wars. This thesis examines the British participation in the 1793 Flanders campaign a broader diplomatic context through the published correspondence of relevant Allied military and political leaders. Traditional accounts of this campaign present a narrative of defeat and condemn the Allies for their failure to achieve in 1793 the accomplishments of the sixth coalition twenty years later. Such a perspective obscures a clear understanding of the reasons for Allied actions. This thesis seeks to correct this distortion by critically analyzing the relationship between British diplomacy within the Coalition and operations in Flanders. Unable to achieve victory on their own strength, the British used their expeditionary force in Flanders as diplomatic leverage to impose their objectives on the other powers at war with France. digital.library.unt.edu/ark:/67531/metadc283820/
Energy and Archetype: A Jungian Analysis of The Four Zoas by William Blake
The purpose of this study is to examine the parallels between the tenets of Carl Jung's psychology and the mythopoeic structure of Blake's poem, The Four Zoas. The investigation is divided into three chapters. The first deals with the major conceptual parallels between the intellectual systems of the two men. The second is a detailed analysis of the poem, and the third concludes the study by discussing the originality of Blake's thought. Blake anticipated much of Jung's psychology. The parallels between the two are so strong that each man seems to corroborate and validate the opinions and insights of the other. The extent to which he foreshadows Jung reveals Blake to be one of the most original thinkers of any period of time. digital.library.unt.edu/ark:/67531/metadc663705/
Energy-Aware Time Synchronization in Wireless Sensor Networks
I present a time synchronization algorithm for wireless sensor networks that aims to conserve sensor battery power. The proposed method creates a hierarchical tree by flooding the sensor network from a designated source point. It then uses a hybrid algorithm derived from the timing-sync protocol for sensor networks (TSPN) and the reference broadcast synchronization method (RBS) to periodically synchronize sensor clocks by minimizing energy consumption. In multi-hop ad-hoc networks, a depleted sensor will drop information from all other sensors that route data through it, decreasing the physical area being monitored by the network. The proposed method uses several techniques and thresholds to maintain network connectivity. A new root sensor is chosen when the current one's battery power decreases to a designated value. I implement this new synchronization technique using Matlab and show that it can provide significant power savings over both TPSN and RBS. digital.library.unt.edu/ark:/67531/metadc5438/
Energy Distribution of Sputtered Neutral Atoms from a Multilayer Target
Energy distribution measurements of sputtered neutral particles contribute to the general knowledge of sputtering, a common technique for surface analysis. In this work emphasis was placed on the measurement of energy distribution of sputtered neutral atoms from different depths. The liquid Ga-In eutectic alloy as a sample target for this study was ideal due to an extreme concentration ratio gradient between the top two monolayers. In pursuing this study, the method of sputter-initiated resonance ionization spectroscopy (SIRIS) was utilized. SIRIS employs a pulsed ion beam to initiate sputtering and tunable dye lasers for resonance ionization. Observation of the energy distribution was achieved with a position-sensitive detector. The principle behind the detector's energy resolution is time of flight (TOF) spectroscopy. For this specific detector, programmed time intervals between the sputtering pulse at the target and the ionizing laser pulse provided information leading to the energy distribution of the secondary neutral particles. This experiment contributes data for energy distributions of sputtered neutral particles to the experimental database, required by theoretical models and computer simulations for the sputtering phenomenon. digital.library.unt.edu/ark:/67531/metadc2657/
Energy Harvesting Wireless Piezoelectric Resonant Force Sensor
The piezoelectric energy harvester has become a new powering option for some low-power electronic devices such as MEMS (Micro Electrical Mechanical System) sensors. Piezoelectric materials can collect the ambient vibrations energy and convert it to electrical energy. This thesis is intended to demonstrate the behavior of a piezoelectric energy harvester system at elevated temperature from room temperature up to 82°C, and compares the system’s performance using different piezoelectric materials. The systems are structured with a Lead Magnesium Niobate-Lead Titanate (PMN-PT) single crystal patch bonded to an aluminum cantilever beam, Lead Indium Niobate-Lead Magnesium Niobate-Lead Titanate (PIN-PMN-PT) single crystal patch bonded to an aluminum cantilever beam and a bimorph cantilever beam which is made of Lead Zirconate Titanate (PZT). The results of this experimental study show the effects of the temperature on the operation frequency and output power of the piezoelectric energy harvesting system. The harvested electrical energy has been stored in storage circuits including a battery. Then, the stored energy has been used to power up the other part of the system, a wireless resonator force sensor, which uses frequency conversion techniques to convert the sensor’s ultrasonic signal to a microwave signal in order to transmit the signal wirelessly. digital.library.unt.edu/ark:/67531/metadc407829/

Energy Paths and Political Commitments: Their Roles in Environmental Inequality
Decentralized renewable energy procurement has gained traction in recent years for its potential to alleviate rural energy poverty and environmental degradation in developing countries. Hence, this study investigates if deploying renewable energy can mitigate rural energy poverty in developing countries as often claimed. Because any energy regime cannot be initiated or sustained without the conviction of local political leaders, the study also evaluates the extent to which government investments in the development of renewable energy technologies and the energy sector, affect the environmental quality (i.e. greenhouse gas emissions) of developing countries. Energetic theory and environmental inequality constitute the key conceptual premises guiding this study. Ordinary least squares regression is utilized to analyze the relationship between key variables. The results reveal that as of 2010, use of renewable energy can indeed support rural electrification. Higher GNI per capita and use of conventional fuels are also positively related to rural electrification, all else equal. As for environmental degradation in 2005 and 2008, R&D investments actually tend to increase GHG emissions; procuring energy from either renewable or non-renewable sources is however, found to be environmentally detrimental, net of all other variables. Finally, some evidence is found for the role of aid funds and multilateral debt in abating GHG emissions. digital.library.unt.edu/ark:/67531/metadc500097/
Energy Policy in the Republic of China and Japan, 1970-1985: A Comparative Examination of Energy Politics and Policies
The impact of the energy crises in the 1970s hit all oil-importing countries much harder than it hit countries endowed with domestic supplies of energy. Energy politics and policies for the oil-importing countries have become vital issues that need to be examined. The purpose of this dissertation is to examine and compare the energy politics and policy processes in the Republic of China (ROC) and Japan during the period of 1970-1985. The study focuses on the politics of energy policies, using a policy analysis or systems framework for examining the policy processes in the two countries. A comparison is made of energy environments, the political actors, the institutions, and finally the substance of energy policy. An assessment is then made of the effects or consequences of energy policies on these two countries. In attempting to study energy politics and policies in these two Asian countries, the researcher began with a policy model or conceptual schema of energy politics from which the researcher raised a number of research questions. These questions were used to guide the direction of the study. A comparison was first made of energy systems, and then the major actors in the energy resources field were identified by comparing the political systems. Comparison of the political systems in energy politics helped to explain the differences in the political outcomes of energy policy. An assessment was made by using a series of multiple regression models to assess and compare the consequences of energy policies in these two countries. The final purpose of this dissertation is to develop a conceptual model or framework, for understanding the complexity, uncertainty, and interrelatedness of energy policies. The researcher concludes that comparative policy studies are useful and provide insights which otherwise would be missed. digital.library.unt.edu/ark:/67531/metadc330806/
Energy Usage While Maintaining Thermal Comfort : A Case Study of a UNT Dormitory
Campus dormitories for the University of North Texas house over 5500 students per year; each one of them requires certain comfortable living conditions while they live there. There is an inherit amount of money required in order to achieve minimal comfort levels; the cost is mostly natural gas for water and room heating and electricity for cooling, lighting and peripherals. The US Department of Energy has developed several programs to aid in performing energy simulations to help those interested design more cost effective building designs. Energy-10 is such a program that allows users to conduct whole house evaluations by reviewing and altering a few parameters such as building materials, solar heating, energy efficient windows etc. The idea of this project was to recreate a campus dormitory and try to emulate existent energy consumption then try to find ways of lowering that usage while maintaining a high level of personal comfort. digital.library.unt.edu/ark:/67531/metadc103319/
Engaging Lives: a Nomadic Inquiry Into the Spatial Assemblages and Ethico-aesthetic Practices of Three Makers
This research is a nomadic inquiry into the ethics and aesthetics of three makers’ social and material practices. Deleuze’s concept of the nomad operated in multiple ways throughout the process, which was embedded in performative engagements that produced narratives of becoming. Over four months, I built relationships with three people as I learned about the ethico-aesthetic significance of their daily practices. The process started by interviewing participants in their homes and expanded over time to formal and informal engagements in school, community, and agricultural settings. I used Guattari’s ecosophical approach to consider how subjectivity was produced through spatial assemblages by spending time with participants, discussing material structures and objects, listening to personal histories, and collaboratively developing ideas. Participants included a builder who repurposed a missile base into a private residence and community gathering space, an elementary art teacher who practiced urban homesteading, and a young artist who developed an educational farm. The research considers the affective force of normalized social values, the production of desire by designer capitalism, and the mutation of life from neoliberal policies. Our experiences illuminate the community-building potential of direct encounters and direct exchanges. The project generates ideas for becoming an inquirer in the everyday and reveals possibilities for producing pedagogical experiences through collective and dissensual action. Ultimately, the project produces hope for performative and anti-disciplinary approaches to education, rupturing false divisions that fragment the force of thought, to produce, instead, aesthetic experiences that privilege processes and are based in direct and collective engagements with life. digital.library.unt.edu/ark:/67531/metadc500105/
Engineered Microbial Consortium for the Efficient Conversion of Biomass to Biofuels
Current energy and environmental challenges are driving the use of cellulosic materials for biofuel production. A major obstacle in this pursuit is poor ethanol tolerance among cellulolytic Clostridium species. The first objective of this work was to establish a potential upper boundary of ethanol tolerance for the cellulosome itself. The hydrolytic function of crude cellulosome extracts from C. cellulolyticum on carboxymethyl cellulose (CMC) with 0, 5, 10, 15, 20 and 25% (v/v) ethanol was determined. Results indicated that the endoglucanase activity of the cellulosome incubated in 5% and 10% ethanol was significantly different from a control without ethanol addition. Furthermore a significant difference was observed in endoglucanase activity for cellulosome incubated in 5%, 10%, 15%, 20% and 25% ethanol in a standalone experiment. Endoglucanase activity continued to be observed for up to 25% ethanol, indicating that cellulosome function in ethanol will not be an impediment to future efforts towards engineering increasing production titers to levels at least as high as the current physiological limits of the most tolerant ethanologenic microbes. The second objective of this work was to study bioethanol production by a microbial co-culture involving Clostridium cellulolyticum and a recombinant Zymomonas mobilis engineered for the utilization of oligodextrans. The recombinant Z. mobilis ZM4 pAA1 and wild type ZM4 were first tested on RM medium (ATCC 1341) containing 2% cellobiose as the carbon source. Ethanol production from the recombinant Z. mobilis was three times that observed from the wild type Z. mobilis. Concomitant with ethanol production was the reduction in OD from 2.00 to 1.580, indicating the consumption of cellobiose. No such change in OD was observed from the wild type. The recombinant ZM4 was then co-cultured with C. cellulolyticum using cellobiose and microcrystalline cellulose respectively as carbon sources. Results indicate that the recombinant ZM4 acted synergistically with C. cellulolyticum to utilize 2.0 g L-1 cellobiose, producing as much as 0.40 mM concentration of ethanol whereas only 0.20 mM ethanol was detected for the wild type ZM4 co-cultured with C. cellulolyticum under the same conditions. A co-culture of the recombinant ZM4 and C. cellulolyticum using 7.5 g L-1 microcrystalline cellulose gave lower ethanol yield than when using cellobiose. In the latter case, the recombinant began producing ethanol in 5 days whereas the wild type required 10 days to produce detectable ethanol. Future efforts will concentrate on identifying the correct concentration of cellulosic substrate at which synergy will be observed using the recombinant ZM4 and other cellulose degrading microorganisms, as well as optimizing medium formulations to better support both organisms. digital.library.unt.edu/ark:/67531/metadc699973/
England and the International Monetary System of the Nineteenth Century
There were two international standards in the nineteenth century, the theoretical gold standard and the historical sterling standard. The primary interest of this thesis is the latter, although the theoretical framework of the gold standard will also be examined. Because of its role in the London money market, particular attention will be given to the Bank of England. Since the Bank and the international standards were products of the evolutionary and revolutionary changes which occurred in Britain during the eighteenth and nineteenth centuries, an attempt will be made to examine them within their historical context. digital.library.unt.edu/ark:/67531/metadc108206/

English Devotional Song of the Seventeenth Century in Printed Collections from 1638 to 1693: A Study of Music and Culture
Seventeenth-century England witnessed profound historical, theological, and musical changes. A king was overthrown and executed; religion was practiced fervently and disputed hotly; and English musicians fell under the influence of the Italian stile nuovo. Many devotional songs were printed, among them those which reveal influences of this style. These English-texted sacred songs for one to three solo voices with continuo--not based upon a previously- composed hymn or psalm tune—are emphasized in this dissertation. Chapter One treats definitions, past neglect of the genre by scholars, and the problem of ambiguous terminology. Chapter Two is an examination of how religion and politics affected musical life, the hiatus from liturgical music from 1644 to 1660 causing composers to contribute to the flourishing of devotional music for home worship and recreation. Different modes of seventeenth-century devotional life are discussed in Chapter Three. Chapter Four provides documentation for use of devotional music, diaries and memoirs of the period revealing the use of several publications considered in this study. Baroque musical aesthetics applied to devotional song and its raising of the affections towards God are discussed in Chapter Five. Chapter Six traces the influence of Italian monody and sacred concerto on English devotional song. The earliest compositions by an Englishman working in the stile nuovo are Henry Lawes' 1638 hymn tunes with continuo. Collections of two- and three-voice compositions by Child, the Lawes brothers, Wilson, and Porter, published from 1639 to 1657, comprise Chapter Seven, as well as early devotional works of Locke. Chapter Eight treats Restoration devotional song-- compositions for one to three voices and continuo, mostly of a more secular and dramatic style than works discussed in earlier. The outstanding English Baroque composers--Locke, Humfrey, Blow, and Purcell--are represented, and the apex of this style is found in the latest seventeenth-century publication of devotional song, Henry Playford's Harmonia sacra, (1688, 1693). digital.library.unt.edu/ark:/67531/metadc331253/

English language learners: Does summer school make a difference in young children's literacy scores?
Access: Use of this item is restricted to the UNT Community.
Many school districts consider literacy and oral language as a top priority for pre-kindergarten students. In the district under study, pre-kindergarten English language learner (ELL) students are encouraged to attend a special summer school program to increase their oral language ability in English. This study compared three groups of children: ELL students attending summer school v. ELL students not attending summer school v. English speaking students not attending summer school. The students' primary reading inventory scores from the end of pre-kindergarten to the middle of kindergarten in the areas of reading, writing and oral language were compared. As expected, ELLs who attended summer school showed significant growth in oral language development from the beginning of summer school to the end of summer school. While it was hypothesized that ELL students attending summer school would show more improvement in oral language than other children over time, there was no significant difference between summer school and non-summer school children's scores by the middle of kindergarten. digital.library.unt.edu/ark:/67531/metadc5305/
English Methods Courses in Texas Preparation for the Essential Elements
This study analyzes the congruence between the objectives of secondary-level English methods courses in Texas universities and the objectives of the state-mandated high school curriculum (the essential elements) in language arts. A questionnaire was used to obtain information from 26 English methods instructors at 22 universities in Texas. The data obtained from these questionnaires reveal that these instructors strongly emphasize preparing prospective English teachers to teach the essential elements of composition. Other significant findings include: (1) the lack of emphasis in the English methods course on strategies for teaching the essential elements of language, when those elements are unrelated to composition, and (2) the lack of uniformity which characterizes the organization of the English methods course at major Texas universities. digital.library.unt.edu/ark:/67531/metadc500661/
