Reflections of Other/Reflections of Self
Access: Use of this item is restricted to the UNT Community.
This Thesis collection contains a critical preface and five stories. The preface, “Reflejos y Reflexiones” (translated: Images and Thoughts), addresses the issues of writing the cultural or gendered Other; these issues include methodology, literary colonialism, a dialogue between works, and creating distance through defamiliarizing the self. “Perennials” is the story of Noemi Tellez, an immigrant to the U.S. who must choose between working and taking care of her family. In “Load Bearing” Luis, the eldest child, faces his family and friends on one of his last days before moving away to college. “La Monarca” deals with Lily's, the youngest daughter, struggle to mediate a place between her friends and her family. In “Reflections in the River,” Arabela, the second youngest, faces the ghost of an unwanted pregnancy and La Llorona. “La Cocina de Su Madre” is the story of Magda, the oldest daughter, and her own teenage girl, Natalia, as they attempt to find themselves in a new town after moving a thousand miles from home. digital.library.unt.edu/ark:/67531/metadc3189/
Reflections of Revolution: Le Figaro, Le Monde, and Public Opinion in France during the Algerian Conflict (1954-1962)
This thesis is an examination of the printed media in France (1955-1963), as represented by two mainstream newspapers: Le Monde (left-centrist) and Le Figaro (right-centrist). Using these newspapers, as well as Gallup polls recorded at the time, this study explores correlations of what was reported in newspapers and how French public opinion evolved during the course of the war. These two major sources of information are shown to have given contradictory information, thus accounting for some of the paradoxes found in public opinion polls. Specifically, the paradoxes analyzed in the study concern the Front de Libération Nationale (FLN) and the Pieds-Noirs (the European population of North Africa). digital.library.unt.edu/ark:/67531/metadc3360/
Reflections on diversity: Graduate perceptions of campus climate at Dallas Theological Seminary, 1996-2005.
The purpose of this study was to determine how graduates of master's degree programs perceived the ethnic and cultural climate at Dallas Theological Seminary (DTS) during their enrollment there. The population (N=2,223) consisted of graduates of master's degree programs who attended Dallas Seminary from 1996-2005. The study utilized a non-experimental design methodology using a mailed survey questionnaire. A 37.2 % response rate was achieved. Most results were statistically significant at the .05 alpha level utilizing chi-square goodness-of-fit tests. digital.library.unt.edu/ark:/67531/metadc3621/
Reflections on the Development of Children of Alcoholics
Access: Use of this item is restricted to the UNT Community.
The specific purpose of this study was to try and understand why unique experiences of living with an alcoholic parent could create developmental deficits which emotionally challenge COAs' when faced with the life lessons a college environment offers. This study offered four possible explanations for experiencing challenges in its theoretical background: (1) psychosocial development, (2) the epistemology of alcoholism and its effects on the family, (3) personality development and the concurrence of building resilience, and (4) the college environment itself, with the phenomenon of binge drinking--forcing COAs to confront family alcoholism. A total of 7 participated in this study--4 men and 3 women. Despite the dynamic differences in the answers overall, all 7 participants acknowledged one important concept. When the participants were asked about their own drinking habits, each participant said, though in different ways, they had to be careful with their drinking habits. Participants seemed to be aware that whether alcoholism is genetic or a learned addiction, they were at risk of becoming alcoholics themselves. This study found overall, as previous literature suggests, no matter how COAs are studied, they are found to be a heterogeneous population. Specifically, this study's results points out that they are indeed heterogeneous, yet similar in that all participants in this study, it could be argued, exhibit some vulnerability in regard to parental alcoholism. digital.library.unt.edu/ark:/67531/metadc2742/
Reform and change in police education: Examining the variations in the top-down and bottom-up structures in the process of implementation.
This study examines the variations in the practice of implementation in different implementation structures using the case of police education reforms that were undertaken by the Turkish National Police (TNP) in 2001 and 2003. Differentiations and similarities in the top-down and bottom-up structures while practicing the process of implementation were investigated in this study. First, the study provides a comprehensive understanding of the process of implementation and structure of implementation. Second, the study introduces TNP education reforms and explains the reasons for the reform. Third, a quantitative approach is used to measure the success of the TNP educational reforms. Specifically, multiple regression analysis, one-way analysis of variance (ANOVA), and post hoc tests are used to clarify if police performance in the TNP has improved since the reforms. Fourth, the study uses a qualitative approach to find out how features associated with top-down or bottom up approaches were involved in the process of implementation of the educational reforms. Finally, based upon the views of the participants in the qualitative analysis, the study examines the variations in the practice of implementation between decision makers and the street level bureaucrats. digital.library.unt.edu/ark:/67531/metadc11028/
Reform Government in Dallas 1927-1940
In the late nineteenth and early twentieth centuries Progressive reformers attacked the problem of corruption and lack of efficiency in city government. Reform groups in individual cities banded together in the National Municipal League and, because they believed that partisan politics were the root of the problem, attempted to devise a system which would remove politics from municipal government. Their work culminated in the introduction of the city manager, or as it is often called council-manager, form of city government. Under this plan, which closely resembles the organization of a business corporation, the elected council would serve as a board of directors and the city manager as the operating head of city government. Reformers hoped that by taking the day-to-day decisions out of the hands of elected officials and placing them in the hands of a professionally trained manager they might remove the stigma of corruption and partisanship from city government and promote efficiency. Whether this plan as it was originally conceived was or was not successful in Dallas is the subject of this thesis. digital.library.unt.edu/ark:/67531/metadc131422/
The Reform of Medical Education in the United States, 1900-1932
In 1900 the United States had more medical schools than the rest of the world combined. Many of them were commercial institutions devoted to making profits rather than to educating men to perform competently within the medical profession. The profit incentive precipitated low educational standards and made American medical practice decidedly inferior to medical practice almost anywhere else in the civilized world. By 1900 medical education had become pernicious, threatening the health of the nation and the future of the American medical profession. This thesis discusses the efforts to reform medical education practices. digital.library.unt.edu/ark:/67531/metadc131478/
The Reformation-era Church courts of England: A study of the acta of the archidiaconal and consistory court at Chester, 1540-1542
Access: Use of this item is restricted to the UNT Community.
Much work has been done over the last fifty years in the study of the English ecclesiastical courts. One court that thus far has escaped much significant scholarly attention, however, is the one located in Chester, England. The author analyzes the acta of that court in order to determine what types of cases were being heard during the years 1540-42. His analysis shows that the Chester court did not deviate significantly from the general legal and theological structure and function of Tudor church courts of the period. digital.library.unt.edu/ark:/67531/metadc2461/
Reforming Ritual: Protestantism, Women, and Ritual on the Renaissance Stage
My dissertation focuses on representations of women and ritual on the Renaissance stage, situating such examples within the context of the Protestant Reformation. The renegotiation of the value, place, and power of ritual is a central characteristic of the Protestant Reformation in early modern England. The effort to eliminate or redirect ritual was a crucial point of interest for reformers, for most of whom the corruption of religion seemed bound to its ostentatious and idolatrous outer trappings. Despite the opinions of theologians, however, receptivity toward the structure, routine, and familiarity of traditional Catholicism did not disappear with the advent of Protestantism. Reformers worked to modify those rituals that were especially difficult to eradicate, maintaining some sense of meaning without portraying confidence in ceremony itself. I am interested in how early Protestantism dealt with the presence of elements (in worship, daily practice, literary or dramatic representation) that it derogatorily dubbed popish, and how women had a particular place of importance in this dialogue. Through the drama of Shakespeare, Webster, and Middleton, along with contemporary religious and popular sources, I explore how theatrical representations of ritual involving women create specific sites of cultural and theological negotiation. These representations both reflect and resist emerging attitudes toward women and ritual fashioned by Reformation thought, granting women a particular authority in the spiritual realm. digital.library.unt.edu/ark:/67531/metadc5439/
Reformulating a link between social influence network theory and status characteristics theory and a method for testing that link.
The impact of social influence from others on choices made by subjects and how this influence accumulates was studied by secondary analysis of reported experimental data. To explain this impact a link is proposed between social influence network theory (SINT) and status characteristics theory (SCT). The link formula transforms stay probabilities for different status relationships of subject with one disagreeing other agent into horizontal axis coordinate values while stay probabilities of subject given two disagreeing others are transformed into vertical-axis coordinate values corresponding to the horizontal axis values for further analyses. The results support the utility of the proposed link between the two theories. digital.library.unt.edu/ark:/67531/metadc5271/
Refugees: Achievement and Conflict
Currently, there are more than 30 million refugees and internally displaced people in the world. Since the 1970s, after the Vietnam War, international organizations and many countries have supported refugees financially, however, they all have different definitions for a refugee. Refugees who desire peace or freedom and resettle in new countries have had remarkable economic, social, and educational achievement, especially Indochinese people in the US. However, refugees who flee from conflicts have often faced new conflicts in their host society. Both refugees and the host countries experience economic and social burden, however, refugees struggle and try to escape from their economic dependency from the local government. If refugee achievements continue, they could exceed the US educational and social norm in the future. digital.library.unt.edu/ark:/67531/metadc5837/
Region aware DCT domain invisible robust blind watermarking for color images.
The multimedia revolution has made a strong impact on our society. The explosive growth of the Internet, the access to this digital information generates new opportunities and challenges. The ease of editing and duplication in digital domain created the concern of copyright protection for content providers. Various schemes to embed secondary data in the digital media are investigated to preserve copyright and to discourage unauthorized duplication: where digital watermarking is a viable solution. This thesis proposes a novel invisible watermarking scheme: a discrete cosine transform (DCT) domain based watermark embedding and blind extraction algorithm for copyright protection of the color images. Testing of the proposed watermarking scheme's robustness and security via different benchmarks proves its resilience to digital attacks. The detectors response, PSNR and RMSE results show that our algorithm has a better security performance than most of the existing algorithms. digital.library.unt.edu/ark:/67531/metadc9748/
Regional accent discrimination in hiring decisions: A language attitude study
Evidence is presented to support the notion that US regional accents influence decisions in the hiring process. Fifty-six people who hire for a variety of corporations participated in a computerized survey, during which they listened to speakers from regions of the US reading the same passage. Respondents judged the speakers on personal characteristics commonly considered in hiring decisions, attempted to identify the speakers' regions, and selected job categories for each speaker, in addition to providing information about their own linguistic security. Results indicate: 1) judgments based on regional accents strongly correlate to selection of job categories, 2) respondents were not able to identify regional accents correctly, and 3) negative judgments were assigned to the speakers of accents that were correctly identified. digital.library.unt.edu/ark:/67531/metadc2623/
Regional airline qualifications: A study in the marketability of higher education graduates.
The recent emergence and growth of the regional airlines in the United States has placed a strain on the supply of pilots that are needed for staffing scheduled flights. This present pilot shortage is presenting challenges for 2-year colleges and 4-year universities with aviation programs to produce more pilot graduates in less time to meet the staffing demands made by the regional airlines. With this shortage, the pressing issues of how to train and hire qualified pilots to fly technologically advanced regional airline jet aircraft have forced the industry to demand more aviation skills from a shrinking market of aviation pilot candidates. Colleges and universities with aviation programs have been forced to compete with outside private aviation schools on a larger scale in the training of collegiate students for airline employment opportunities. The primary purpose of this study was to expose any inadequacies in the higher-education aviation curricula and to propose changes needed to better qualify aviation students in the hiring process at regional air carriers. This study concentrated on the principle that higher education is necessary for advancing a pilot's aptitudes and abilities to perform the highly technical tasks of a professional pilot in a regional airline environment. The avenues of obtaining aviation experience along with flight certificates and ratings in an academic environment from 2-year colleges and 4-year universities with aviation programs is examined, along with qualifying these schools with the criteria regional airlines expects from new pilots hired. A survey was used to poll the pilots from two regional airlines that were based in Texas. By analyzing the responses from the returned surveys, the quality of training that existed in higher education aviation programs was revealed. The study confirmed the value of advising a path of higher education for students embarking on an aviation career as a pilot for a regional airline. The study concluded that 2-year colleges and 4-year universities with aviation programs are meeting the present demands made by the regional airlines. digital.library.unt.edu/ark:/67531/metadc5181/

Regional Economic Impact of Texas Motor Speedway: A Simulation
This study proposes a method for measuring the regional economic impact of a relatively new sport: stock car racing. Although research on the economic impact of most major league sports is abundant, little has been written on stock car racing. The purpose of this paper is to estimate, through a simulation, the regional economic impact of Texas Motor Speedway. The study finds that the Texas Motor Speedway boosted economic activity by $87,179,367 in 1998 from racetrack operations, and supported 5,300 jobs paying $22,293,135 in earnings. In addition, expenditures by speedway visitor from outside the region are estimated at $22,985,200, further increasing the total local economic activity by $49 million. digital.library.unt.edu/ark:/67531/metadc2610/

The Regional Impacts of Climate Change: An Assessment of Vulnerability
The Intergovernmental Panel on Climate Change (IPCC) was jointly established by the World Meteorological Organization and the United Nations Environment Programme in 1988 to assess the scientific and technical literature on climate change, the potential impacts of changes in climate, and options for adaption to and mitigation of climate change. Since its inception, the IPCC has produced a series of Assessment Reports, Special Reports, Technical Papers, methodologies and other products which have become standard works of reference, widely used by policymakers, scientists and other experts. This Special Report, which has been produced by Working Group II of the IPCC, builds on the Working Group's contribution to the Second Assessment Report (SAR), and incorporates more recent information made available since mid-1995. It has been prepared in response to a request from the Subsidiary Body for Scientific and Technological Advice (SBSTA) of the UN Framework Convention on Climate Change (UNFCCC). It addresses an important question posed by the Conference of the Parties (COP) to the UNFCCC, namely, the degree to which human conditions and the natural environment are vulnerable to the potential effects of climate change. The report establishes a common base of information regarding the potential costs and benefits of climatic change, including the evaluation of uncertainties, to help the COP determine what adaptation and mitigation measures might be justified. The report consists of vulnerability assessments for 10 regions that comprise the Earth's entire land surface and adjoining coastal seas: Africa, Arid Western Asia (including the Middle East), Australasia, Europe, Latin America, North America, the Polar Regions (The Arctic and the Antarctic), Small Island States, Temperate Asia and Tropical Asia. It also includes several annexes that provide information about climate observations, climate projections, vegetation distribution projections and socioeconomic trends. digital.library.unt.edu/ark:/67531/metadc11996/

Register Unification in Light of Twentieth-Century Vocal Pedagogy
Access: Use of this item is restricted to the UNT Community.
The registers of the singing voice, as commonly understood by singers, refer to the different vocal qualities induced by adjustments at the level of the larynx and of the vocal tract. This explains why register unification can be approached either one or a combination of the following procedures: (1) resonance alignment through vowel modification, (2) register alignment through intensity exercises. The wide-spread acceptance of vowel modification has made singers reluctant in exploring other avenues of register development. If registers are laryngeally derived, there should be another way of register unification, which directly addresses the coordination of the laryngeal muscles. In support of this argument, this thesis investigates the teaching practices of a group of twentieth-century American voice teachers, who rely on intensity manipulation as the primary means for enhancing the register adjustments. Intensity exercises such as the messa di voce has long been practiced in historical pedagogy, but it is not until now that voice science confirmed its significance in register coordination. digital.library.unt.edu/ark:/67531/metadc5527/

Regulation and Political Costs in the Oil and Gas Industry: An Investigation of Discretion in Reporting Earnings and Oil and Gas Reserves Estimates
This study investigates the use of discretion by oil and gas companies in reporting financial performance and oil and gas reserve estimates during times of high political scrutiny resulting from increases in energy prices. Hypotheses tested in prior literature state that companies facing the risk of increasing taxes or new regulations reduce reported earnings to reduce this risk. This study uses a measure of high profitability (rank order of return on assets relative to industry peers) to identify oil and gas companies more likely to manage earnings during the period from 2002 to 2008. Two measures of discretionary accruals (total and current discretionary accruals), and a measure of discretionary depreciation, depletion, and amortization (DDA) were used as indicators of discretion exercised in reporting earnings. Data on oil and gas reserve disclosures was also hand-collected from Forms 10-K to investigate whether managers use reserve estimate revisions to reduce reported earnings through increasing the annual depletion expense. Results suggest that both oil and gas refining and producing firms use negative discretionary accruals to reduce reported earnings. Results also indicate that profitability is an important determinant of the use of negative discretionary accruals by these companies regardless of the time period examined. There is also evidence that oil and gas producing firms opportunistically revise their oil and gas reserve estimates to increase depreciation, depletion, and amortization expense during periods of high oil prices. digital.library.unt.edu/ark:/67531/metadc30481/
The Regulation of Medically Assisted Procreation in Europe and Related Nations and the Influence of National Identity, Social Cultural, and Demographic Differences
This study details the Medically Assisted Procreation regulations in thirty-five nation-states, and explores the influence of national identity, social cultural and demographic differences on these regulations. Detailed data were gathered from ministries of health, offices of prime ministers, embassy staff, and others on regulations for each nation. These data were used to categorize the nations in regard to MAP legislation status and regulatory policy regarding marital or age restrictions; posthumous conception; sperm, ovum, or embryo donation, surrogacy; and policy on handling donors. Possible associations between national identity, social cultural, and demographic data for each nation and their regulations were explained. The thirty-five nations were treated as a population with common geographical and political ties. PRE methods, and eta coefficients were used to assess the associations. Sixteen nations have adopted MAP legislation, eight nations have either alternative regulatory guidelines or partial structures, four nations have legislation pending and possibly some laws, and seven nations are unregulated. Based upon statistical analysis, language group emerges as an important indicator for differences in MAP regulations. For example knowing a nation's language group enabled percent improved prediction of that nation's regulatory handling of embryo donation. The percent GDP spent on health care was found to have a substantial or moderate association with most regulations. The findings of this study indicate that the cultural roots associated with national identity as well as economic circumstances such as health care budgets impact the policy making process responsible for the regulation of MAP in Europe. Among other mediating circumstances, MAP related family law cases brought to the European Court of Human Rights create an accumulation of judge-made law, which help create a common European standard. This study of the European region provides a baseline for further research and a reference for cross cultural comparisons. digital.library.unt.edu/ark:/67531/metadc3192/
Regulation of pyrimidine biosynthesis and virulence factor production in wild type, Pyr- and Crc- mutants in Pseudomonas aeruginosa.
Previous research in our laboratory established that pyrB, pyrC or pyrD knock-out mutants in Pseudomonas aeruginosa required pyrimidines for growth. Each mutant was also discovered to be defective in the production of virulence factors. Moreover, the addition of exogenous uracil did not restore the mutant to wild type virulence levels. In an earlier study using non-pathogenic P. putida, mutants blocked in one of the first three enzymes of the pyrimidine pathway produced no pyoverdine pigment while mutants blocked in the fourth, fifth or sixth steps produced copious quantities of pigment, just like wild type P. putida. The present study explored the correlation between pyrimidine auxotrophy and pigment production in P. aeruginosa. Since the pigment pyoverdine is a siderophore it may also be considered a virulence factor. Other virulence factors tested included casein protease, elastase, hemolysin, swimming, swarming and twitching motilities, and iron binding capacity. In all cases, these virulence factors were significantly decreased in the pyrB, pyrC or pyrD mutants and even in the presence of uracil did not attain wild type levels. In order to complete this comprehensive study, pyrimidine mutants blocked in the fifth (pyrE) and sixth (pyrF) steps of the biosynthetic pathway were examined in P. aeruginosa. A third mutant, crc, was also studied because of its location within 80 base pairs of the pyrE gene on the P. aeruginosa chromosome and because of its importance for carbon source utilization. Production of the virulence factors listed above showed a significant decrease in the three mutant strains used in this study when compared with the wild type. This finding may be exploited for novel chemotherapy strategies for ameliorating P. aeruginosa infections in cystic fibrosis patients. digital.library.unt.edu/ark:/67531/metadc5297/

Regulatory Orientation, Message Framing and Influences of Fit on Customer Behaviors
Existing literature on consumer behavior has argued that an individual’s regulatory orientation interacts with message framing. If there is a match between regulatory orientation (promotion versus prevention) and message framing, this results in positive attitudes toward a given advertisement. Conversely, if there is a mismatch, the effect is opposite, i.e., attitudes toward that advertisement are less positive and less favorable. This research extends the term of compatibility by examining how regulatory focus moderates the impact of two aspects of message framing (attribute framing and risky choice framing) on customer perceptions. It also examines whether regulatory fit is created when there are interactions between individuals’ regulatory orientation and message framing and how the fit changes customer perceptions about a message. Specifically, this dissertation provides answers to the following questions: (1) does regulatory fit take place when regulatory focus is compatible with two aspects of message framing (attribute and risky choice)?; (2) does regulatory fit take place when one aspect of message framing (attribute) is compatible with the other (risky choice)?; and (3) how do customer perceptions change if customers experience regulatory fit? The results show that the effects of utilitarian attributes and national brands are dominating and that both promotion- and prevention-oriented customers have higher perceptions of these attributes and brands. The findings of this study have both theoretical and practical implications. Theoretically, this study should enhance our understanding of regulatory focus theory. Practically, the results should provide marketers with more insights into the correlation between message framing and regulatory orientation and the effect of fit on message persuasion, enabling them to develop more effective marketing strategies. digital.library.unt.edu/ark:/67531/metadc149676/
A regulatory role for N-acylethanolamine metabolism in Arabidopsis thaliana seeds and seedlings.
N-Acylethanolamines (NAEs) are bioactive acylamides that are present in a wide range of organisms. Because NAE levels in seeds decline during imbibition similar to ABA, a physiological role was predicted for these metabolites in Arabidopsis thaliana seed germination and seedling development. There is also a corresponding increase of AtFAAH (fatty acid amide hydrolase), transcript levels and activity, which metabolizes NAE to ethanolamine and free fatty acids. Based on whole genome microarray studies it was determined that a number of up-regulated genes that were responsive to NAE were also ABA responsive. NAE induced gene expression in these ABA responsive genes without elevating endogenous levels of ABA. It was also determined that many of these NAE/ABA responsive genes were associated with an ABA induced secondary growth arrest, including ABI3. ABI3 is a transcription factor that regulates the transition from embryo to seedling growth, the analysis of transcript levels in NAE treated seedlings revealed a dose dependent, inverse relationship between ABI3 transcript levels and growth, high ABI3 transcript levels were associated with growth inhibition. Similar to ABA, NAE negatively regulated seedling growth within a narrow window of early seedling establishment. When seedlings are exposed to NAE or ABA within the window of sensitivity, the induction of genes normally associated with the ungerminated desiccation tolerant state resumed. The NAE tolerant FAAH overexpressor and the NAE sensitive FAAH knockout both had a NAE/ABA sensitive window similar to the wild type A. thaliana. The abi3-1 ABA insensitive mutant does not undergo growth arrest upon exposure to ABA, but NAE did induce growth arrest when treated within the sensitivity window. This evidence showed that although NAE functions within an ABA dependent pathway, it also functions in an ABA independent signaling pathway. The FAAH overexpressor is tolerant to NAE through its ability to quickly metabolize NAE from the growth media, yet it is hypersensitive to ABA. The FAAH overexpressor also displayed hypersensitivity to GA, which improved its delayed germination in non-stratified seed, while the FAAH knock out showed GA insensitivity. Overall, these results showed that NAE functions as a negative regulator of germinating seed and seedling growth in ABA dependent and independent signaling pathways, and that altered NAE metabolism may interfere with ABA/GA perception in germinating seed. digital.library.unt.edu/ark:/67531/metadc10978/

The regulatory gene for pyrimidine biosynthesis has been identified and designated pyrR. The pyrR gene product was purified to homogeneity and found to have a monomeric molecular mass of 19 kDa. The pyrR gene is located directly upstream of the pyrBC' genes in the pyrRBC' operon. Insertional mutagenesis of pyrR led to a 50- 70% decrease in the expression of pyrBC', pyrD, pyrE and pyrF while pyrC was unchanged. This suggests that PyrR is a positive activator. The upstream regions of the pyrD, pyrE and pyrF genes contain a common conserved 9 bp sequence to which the purified PyrR protein is proposed to bind. This consensus sequence is absent in pyrC but is present, as an imperfect inverted repeat separated by 11 bp, within the promoter region of pyrR. Gel retardation assays using upstream DNA fragments proved PyrR binds to the DNA of pyrD, pyrE, pyrF as well as pyrR. This suggests that expression of pyrR is autoregulated; moreover, a stable stem-loop structure was determined in the pyrR promoter region such that the SD sequence and the translation start codon for pyrR is sequestered. β-galactosidase activity from transcriptional pyrR::lacZ fusion assays, showed a two-fold in increase when expressed in a pyrR- strain compared to the isogenic pyrR+ strain. Thus, pyrR is negatively regulated while the other pyr genes (except pyrC) are positively activated by PyrR. That no regulation was seen for pyrC is in keeping with the recent discovery of a second functional pyrC that is not regulated in P. aeruginosa. Gel filtration chromatography shows the PyrR protein exists in a dynamic equilibrium, and it is proposed that PyrR functions as a monomer in activating pyrD, pyrE and pyrF and as a dimeric repressor for pyrR by binding to the inverted repeat. A related study discovered that the catabolite repression control (Crc) protein was indirectly involved in pyr gene regulation, and shown to negatively regulate expression of PyrR at the posttranscriptional level. digital.library.unt.edu/ark:/67531/metadc2875/
Rehlet Iraqi (An Iraqi Journey)
Rehlet Iraqi was created to depict an Iraqi refugee family’s struggle after fleeing war-torn Iraq. Their struggle is highlighted with hope and high expectations for a better life within the United States. This film emphasizes the toll that emigration has on the life of a family before and after their arrival to Grand Rapids, Michigan. digital.library.unt.edu/ark:/67531/metadc103406/
Reinforcement Sensitivity Theory and Proposed Personality Traits for the Dsm-v: Association with Mood Disorder Symptoms
The current work assesses the relationship between reinforcement sensitivity theory (RST) and Personality Traits for the DSM-5 (PID-5), to explore the degree to which they are associated with mood disorder symptoms. Participants (N = 138) from a large public university in the South were administered a semi-structured interview to assess for current mood disorder and anxiety symptoms. They were also administered self-report inventories, including the Behavioral Inhibition System (BIS) and Behavioral Approach System (BAS) scales and the Personality Inventory for DSM-5 (PID-5). Results indicate that both the BIS/BAS scales and the PID-5 scales were strongly associated with current mood symptoms. However, the maladaptive personality traits demonstrated significantly greater associations with symptoms compared to the BIS/BAS scales. Results also indicated support for using a 2-factor model of BIS as opposed to a single factor model. Personality models (such as the five factor model) are strongly associated with mood symptoms. Results from this study add to the literature by demonstrating credibility of an alternative five-factor model of personality focused on maladaptive traits. Knowledge of individual maladaptive personality profiles can be easily obtained and used to influence case conceptualizations and create treatment plans in clinical settings. digital.library.unt.edu/ark:/67531/metadc271842/
Reinterpreting Hieronymus Bosch's Table Top of the Seven Deadly Sins and the Four Last Things through the Seven Day Prayers of the Devotio Moderna
Access: Use of this item is restricted to the UNT Community.
This thesis examines Hieronymus Bosch's Table Top of the Seven Deadly Sins and the Four Last Things. Instead of using an iconographical analysis, the thesis investigates the relationship between Bosch's art and the Devotio Moderna, which has been speculated by many Bosch scholars. For this reason, a close study was done to examine the Devotio Moderna and its influence on Bosch's painting. Particular interest is paid to the seven day prayers of the Devotio Moderna, the subjects depicted in Bosch's painting, how Bosch's painting blesses its viewer during the time of one's prayer, and how the use of gaze ties all of these ideas together. digital.library.unt.edu/ark:/67531/metadc2573/

Relation Between the FITNESSGRAM® Ftness Assessment and Self-Reported Physical Activity Questions
The FITNESSGRAM® is regularly used to assess physical fitness (PF) of adolescents. In addition to the PF assessment, the FITNESSGRAM also includes self-report physical activity (PA) items. The purpose of this study was to examine whether the self-report aerobic, muscular strengthening, and flexibility PA behavior items indicated adolescents’ cardiorespiratory, muscular strength, and flexibility fitness and their body composition. Logistic regression analysis was used to examine the relation between the amount of PA and PF status. Adolescents not meeting the recommended PA amount had significantly higher odds of not achieving a healthy fitness status. Meeting the recommended PA amount was associated with achieving healthy PF status. Thus, adolescents’ amounts of aerobic, muscular strengthening, and flexibility PA were an indication of their corresponding health-related PF standard. digital.library.unt.edu/ark:/67531/metadc84291/
