Pathophysiology and Racial/Ethnic Disparities in the Progression of Metabolic Syndrome
Access: Use of this item is restricted to the UNT Community.
Disparities exist in the U.S. between the health status of African American and Hispanic individuals and the health status of non-Hispanic Caucasian individuals across all age groups. Those minority individuals age 55 and over are more likely to suffer from specific health disparities in areas such as diabetes, heart disease, and cancer than their white majority counterparts. Among the most common chronic disorders experienced within this age group are obesity, type II diabetes and cardiovascular disease, all three of which collectively form what has recently become known as metabolic syndrome. As of 2004, metabolic syndrome is diagnosable once criteria are clinically significant for a variety of different risk factors designated by the World Health Organization. However, like many syndromes these criteria are not stable across individuals, and leaves variability between individuals being diagnosed. It has been seen that each of the above mentioned racial/ethnic groups experience the individual risk factors at disproportionate rates, making it plausible that metabolic syndrome could be experienced in distinctly different ways depending upon racial/ethnic background. Using two nationally representative data sets, it is first largely evident that African American and Hispanic individuals are reaching higher peak rates of diabetes and cardiovascular disease much earlier in age than are non-Hispanic Caucasian individuals. The study goes on to reveals that the metabolic syndrome appears to follow one underlying progressive syndrome that begins with obesity and progresses towards heart disease. Each of the racial/ethnic groups experience significantly different progressions of the syndrome across time. Behavioral analysis found significant differences in health behaviors across the three groups; however a more pervasive lack of initiative in practicing preventive health behaviors is also present. The study achieved a higher understanding of individual differences within metabolic syndrome and insight into how and at what time in the lifespan health services can be most beneficial in providing preventive services to culturally diverse populations. digital.library.unt.edu/ark:/67531/metadc5310/

Patronage, Connoisseurship and Antiquarianism in Georgian England: The Fitzwilliam Music Collection (1763-1815)
In eighteenth-century Britain, many aristocrats studied music, participated as amateurs in musical clubs, and patronized London’s burgeoning concert life. Richard Fitzwilliam, Seventh Viscount Fitzwilliam of Merrion and Thorncastle (1745-1816), was one such patron and amateur. Fitzwilliam shaped his activities – participation, patronage, and collecting – in a unique way that illustrates his specialized tastes and interests. While as an amateur musician he sang in the Noblemen’s and Gentlemen’s Catch Club (the premiere social club dedicated to musical performance), he rose to the highest level of patronage by spearheading the Handel Commemoration Festival of 1784 and serving for many years as a Director of the Concert of Antient Music, the most prestigious concert series in Georgian Britain. His lasting legacy, however, was his bequest to Cambridge University of his extensive collection of art, books and music, as well as sufficient funds to establish the Fitzwilliam Museum. At the time of his death, Fitzwilliam’s collection of music was the best in the land, save that in the Royal Library. Thus, his collection is ideally suited for examination as proof of his activities, taste and connoisseurship. Moreover, the music in Fitzwilliam’s collection shows his participation in the contemporary musicological debate, evidenced by his advocacy for ancient music, his agreement with the views of Charles Avison and his support for the music of Domenico Scarlatti. On one side of this debate were proponents of learned, ancient music, such as Fitzwilliam and Avison, whose Essay on Musical Expression of 1752 was a milestone in musical criticism. On the other side of the discussion were advocates for the more modern, “classical” style and genres, led by historian Charles Burney. digital.library.unt.edu/ark:/67531/metadc103327/
A Pattern Oriented Data Structure for Interactive Computer Music
This essay describes a pattern oriented data structure, or PODS, as a system for storing computer music data. It organizes input by sequences or patterns that recur, while extensively interlinking the data. The interlinking process emulates cognitive models, while the pattern processing draws specifically from music cognition. The project aims at creating open source external objects for the Max/MSP software environment. The computer code for this project is in the C and Objective-C computer programming languages. digital.library.unt.edu/ark:/67531/metadc68002/

Patterns of Change in Semantic Clustering in Schizophrenia Spectrum Disorders: What Can it Tell Us about the Nature of Clustering Deficits
Semantic clustering has been used as a measure of learning strategies in a number of clinical populations and has been found to be deficient in individuals with Schizophrenia, but less attention has been paid to the dynamic use of this strategy over the course of fixed-order learning trials. In the current study, we examined this pattern of clustering use over trials in a sample of individuals with Schizophrenia, and explored whether the addition of this dynamic information would help us to better predict specific executive deficits. Results suggested that a decrease in semantic clustering across trials was associated with some executive deficits in the predicted manner. Nonetheless, the overall semantic clustering index generally proved more effective for the purposes, suggesting that in this population, the addition of dynamic information in strategy use is not likely to add considerably to clinical prediction and understanding. digital.library.unt.edu/ark:/67531/metadc2906/

Patterns of verbal communication in children with special needs.
The social interactions between children with special needs, learning disabilities and/or attention deficit disorder (ADHD), were investigated. The children were observed in groups of three/four while creating a cooperative art project. During this activity, their interactions were recorded and coded for patterns of verbal communication. Verbal communication was evaluated through statements reflecting requests for information and materials; helping/cooperation/giving; consideration/positive reinforcement; competitiveness; intrusiveness; rejection; self-image; neutral statements; and persuasiveness. Results indicated that children with special needs tended to engage in a greater frequency of helping/cooperative/giving statements as opposed to any other verbal statements. Specifically, positive statements as opposed to negative statements classified their verbal interactions. These children also appeared to demonstrate more internalizing behaviors than externalizing behaviors. The influence of children's behaviors on children's verbal statements was examined. Results indicated that children who evidenced a disability in reading or language appeared to engage in a greater frequency of cooperative or helping statements than their non-disabled peers. Intrusive tendencies may be associated with the following: presence of a reading disability, absence of ADHD, and absence of a disability in written expression. Additionally, the conversations of children with a disability in mixed receptive language tended to evidence a greater frequency of neutral statements when compared to their peers without a disability. Externalizing behaviors also appeared to be associated with increased use of considerate and encouraging statements. Findings also suggested that intellectual ability may be related to children's verbalizations, but unrelated to children's behaviors. Intellectual functioning appeared to be directly related to children's use of rejecting statements. Upon comparing these findings to previous literature on the social communication between children with and without special needs, it is unclear whether children with special needs evidence a shared communicative culture or ability to interpret communication patterns, which results in more positive communicative interactions. This study has implications for appropriate educational placement, the formation of children's friendships, and the social communication of children with special needs. digital.library.unt.edu/ark:/67531/metadc5290/
Patton's Iron Cavalry - The Impact of the Mechanized Cavalry on the U.S. Third Army
The American military experience in the European Theater of Operations during the Second World War is one of the most heavily documented topics in modern historiography. However, within this plethora of scholarship, very little has been written on the contributions of the United States Cavalry to this era. The six mechanized cavalry groups assigned to the Third Army served in a variety of roles, conducting screens, counter-reconnaissance, as well as a number of other associated security missions for their parent corps and the Army. Although unheralded, these groups made substantial and war-altering impacts for the Third Army. digital.library.unt.edu/ark:/67531/metadc68023/

Paul Hindemith's Septet (1948): A Look Back to Neue Sachlichkeit
In the early 1920s, Gustav Friedrich Hartlaub created a fine arts movement that began in Weimar, Germany, which questioned artistic Expressionism. In 1923, he formed an art exhibition to display new art works of simplicity that were of his anti-Expressionist goal. This exhibition was termed Neue Sachlichkeit, or New Objectivity, and quickly became associated with all fine arts. Music of Neue Sachlichkeit ideals during the 1920s and 1930s began to exhibit anti-Expressionist concepts of form, neoclassicism and limited instrumentation. Paul Hindemith was among the leading figures of Neue Sachlichkeit music. Although Paul Hindemith's Septet (1948) was composed during his later career, it shows many Neue Sachlichkeit traits found previously in the 1920s and 1930s. Characteristics of limited/mixed instrumentation, neoclassic instrumentation and form, and Baroque counterpoint are found in the Septet. These traits can also be head in earlier Neue Sachlichkeit pieces by Hindemith such as Hin und zuruck, op. 45a (1927), Das Marienleben (1922/23, rev. 1948) and Neues vom Tage (1929). Chapter 2 examines the Neue Sachlichkeit movement within the fine arts. Chapter 3 gives a brief biography of Paul Hindemith with a concentration on his influence of Neue Sachlichkeit music of the 1920s and 1930s. This chapter also relates this period of Hindemith's earlier career with his techniques used in later works, such as the Septet. Chapter 4 discusses how the Septet directly relates to the Neue Sachlichkeit fine arts movement. Chapter 5 gives a general analysis of the Septet. This analysis provides the reader with an understanding of the forms and tonal relationships used in the Septet. This summarizes the neoclassicism of the Septet and shows traits of Neue Sachlichkeit. Chapter 6 concludes with an examination of the mixed instrumentation of the Septet. digital.library.unt.edu/ark:/67531/metadc31545/

Paying for the Arts: Fundraising Methods for Secondary Theater Programs
Access: Use of this item is restricted to the UNT Community.
This project in lieu of thesis identifies successful methods of fundraising utilized by a sampling of three secondary theater arts programs from North Texas. Programs were evaluated on their ability to fund their programs and provide a quality arts education for their students. Guidelines for fundraising were developed that allow secondary theater programs to flourish without placing an additional burden on already overextended tax system. Findings were framed in a Marxist socio-economic context, seeking to find some relation between supply-side economics and the failure of certain communities to offer quality arts programs. Marxist philosophy, emphasizing the values of community and shared wealth, served to frame findings in the context of arts programs serving and enhancing their own communities. digital.library.unt.edu/ark:/67531/metadc4250/

A Pedagogical and Analytical Study of Dušan Bogdanović’s Polyrhythmic and Polymetric Studies for Guitar
Polymeter has been a relatively unexplored compositional technique of music of the Common Practice Period. Dušan Bogdanović’s Polyrhythmic and Polymetric Studies for Guitar is recognized in the guitar world as not only an important theoretical treatise, but also a benchmark for more advanced levels of improvisation. Currently, his treatise remains the best source for learning polymetric improvisation on the guitar. My personal contribution stems from the idea that multiple interpretations of thought processes and technical approaches are possible when learning to play polymeters on the guitar. The first section focuses on providing an alternative technical approach towards learning to play polymeters on the guitar by simplifying selected exercises in Bogdanović’s treatise from their original presentation, and demonstrating further possibilities as to how the exercises can be applied in a practical manner to improvisation. The second part reveals through analysis of the Concert Studies 1, 2, and 5 both his innovative improvisatory use of polymeter as a stylistic device, and his ties to traditional ideas of structure. digital.library.unt.edu/ark:/67531/metadc84256/

A pedagogical study and practice guide for significant original euphonium solo compositions for the undergraduate level student.
Euphonium concertos and similar masterworks for euphonium have been recorded, written about, analyzed, and discussed at length numerous times in recent years. Unfortunately, the most frequently studied and performed euphonium solos have been almost completely ignored in this regard. These works are useful for performance by the undergraduate-level euphonium player. Solos in this category are played by strong high school players and undergraduate euphonium students all over the world. These solos receive countless performances and play a crucial role in the development of young euphonium players, yet have never received attention in the form of a published pedagogical guide. The pieces of greater difficulty and substantial length have received more attention for obvious reasons, but solo pieces most useful for the developing euphoniumist need to be analyzed and discussed on a pedagogical level. This paper is a pedagogical guide to commonly played euphonium solos by the undergraduate level student. The three pieces used in this study are Sonatina by Warner Hutchison, Sonata for Unaccompanied Euphonium by Fred Clinard, and Lyric Suite by Donald White. Pertinent background information about each piece is presented in order for the reader to understand the historical context in which it was written. A list of relevant information and minimum performance skills (instrumentation, length, range, articulation skills, etc.) are included for each selection. An analysis of particular sections of each piece are presented for the reader to adequately grasp concepts and practice ideas that are explained, although the bulk of analysis is of a pedagogical nature. The main body of the paper focuses on assisting the reader with ways to approach this solo literature in daily practice as well as effective performance ideas. Particularly troublesome areas of each piece are identified and strategies to overcome common pitfalls and performance errors are noted. digital.library.unt.edu/ark:/67531/metadc3939/
Pedagogical style and influence of Nadia Boulanger on music for wind symphony, an analysis of three works by her students: Copland, Bassett, and Grantham.
Access: Use of this item is restricted to the UNT Community.
An examination of the influences on twentieth-century wind music would be incomplete without the consideration of composer, organist, pianist, conductor, teacher, and critic Nadia Boulanger (1887-1979). Students from the United States began studying with Boulanger between World War I and World War II, and continued to travel to study with her for over fifty years. The respect awarded this legendary French woman was gained as a result of her effectiveness as a teacher, her influence on the development of each student's unique compositional style, and her guidance of an emerging American musical style. The correlation between the teacher's lessons and the compositional output of her students must be explored. Boulanger did not compose specifically for winds, and she did not encourage her students to compose for the wind symphony. However, this document will outline the influence that this powerful pedagogue exerted over the creation of repertoire by her students by providing insight into the pedagogical style and philosophical foundations of Boulanger as reflected in the literature and by the writings, comments, and compositions of three successful students who composed literature for the wind symphony: Aaron Copland (1900-1990), Leslie Bassett (b. 1923), and Donald Grantham (b. 1947). Three significant works for winds will be considered including Copland's Emblems, Bassett's Lullaby for Kirsten, and Grantham's Variations on an American Cavalry Song. digital.library.unt.edu/ark:/67531/metadc5545/
Pediatric Feeding Disorders: A Controlled Comparison of Multidisciplinary Inpatient and Outpatient Treatment of Gastrostomy Tube Dependent Children
The efficacy of multidisciplinary inpatient and outpatient treatment for transitioning children with severe pediatric feeding disorders from gastrostomy tube dependency to oral nutrition was investigated utilizing caloric and fluid intakes as an outcome measure. The study involved 29 children ages 12 months to 5 years of age with gastrostomy tube dependency. Treatments were provided by speech therapists, occupational therapist, dietician and psychologist for a 30 day period. Four treatment groups were evaluated and average intakes compared at 4 observation periods including pretreatment, initiation of treatment, completion of treatment at 30 days and 4 month follow-up. Children receiving inpatient treatment for feeding disorders evidenced significant differences in oral caloric intake from pretreatment to discharge than outpatient treatment (p < .01) and wait list control group (p = .04). Oral caloric intake from discharge to 4 month follow up yielded no significant differences indicating treatment gains were maintained. Change in environment and caretaker showed a significant effect for the inpatient group (d = 1.89). Effects of treatment by age and weight at 4 month follow up were also analyzed. digital.library.unt.edu/ark:/67531/metadc33140/
Pediatric feeding disorders: Efficacy of multidisciplinary inpatient treatment of gastrostomy tube dependent children.
Efficacy of multidisciplinary inpatient treatment of feeding disordered children was sought through retrospective chart review of 40 G-tube dependent children ages 22 months to 7 years. Premature births were 55% of the sample ranging from 23 to 36 weeks gestation. The majority of co-occurring medical conditions included congenital anomalies (50%), gastroesophageal reflux disease (25%) and chronic lung disease (25%). Treatment effect analyzed from pre and post treatment measures of oral and G-tube caloric intakes resulted in a significant difference from admission to discharge for both oral intake, t (39) = 5.76, p < 0.001, d = 1.02, and G-tube dependency, t(39) = 10.94, p < 0.001, d = 2.03 with both showing strong treatment effects. Results indicated a highly reliable and valid method of treating severe pediatric feeding disorders. digital.library.unt.edu/ark:/67531/metadc9113/

The Peer Created Motivational Climate in Youth Sport and Its Relationship to Psychological Outcomes and Intention to Continue in Sport Among Male Adolescents
Social agents in the youth sport domain (coaches, parents, and peers) play a crucial role in developing the motivational approaches of youth sport athletes. One theory which has been useful in explaining the important role of such social agents has been Achievement Goal Theory (Nicholls, 1989). Specifically, Achievement Goal Theory was used to delineate various peer behaviors as being task-involving (Ntoumanis & Vazou, 2005) and was used to predict subsequent relationships relationship between the task-involving motivational-climate created by teammates and athletes’ mastery goal orientations and self-esteem, sport competence, enjoyment, and intention to continue playing sport. Participants were 405 boys aged 12-15 years. Using structural equation modeling, an exploratory analysis and confirmatory analysis revealed that higher levels of task-involving behaviors from peers predicted mastery goal orientation. Participants with higher mastery goal orientation reported greater sport competence, self-esteem, and more enjoyment; enjoyment was the strongest predictor of intention to continue. These findings both emphasize the importance of peer relationships within sport on a variety of motivationally and psychologically salient outcomes and provide direction for the development of training programs targeted to create positive and healthy sport experiences. digital.library.unt.edu/ark:/67531/metadc149560/
Peer Education: Building Community Through Playback Theatre Action Methods
Access: Use of this item is restricted to the UNT Community.
The primary purpose of this study was to use some of the action methods of playback theatre to facilitate the acquisition of knowledge through the experience of building community. The impact of action methods on group dynamics and the relationship among methods, individual perceptions, and the acquisition of knowledge were analyzed. The researcher suggested that playback theatre action methods provided a climate in which groups can improve the quality of their interactions. The Hill Interaction Matrix (HIM) formed the basis for the study's analysis of interactions. Since the researcher concluded there were significantly more interactions coded in the "power quadrant" after training, the researcher assumed that playback theatre action methods are a catalyst for keeping the focus on persons in the group, encouraging risk-taking behaviors, and producing constructive feedback between members. Based on session summaries, individual interviews, and an analysis of the Group Environment Scale (GES), the training group became more cohesive, became more expressive, promoted independence, encouraged self-discovery, and adapted in innovative ways. The experience of an interconnected community created a space where positive growth could occur. The researcher concluded that the process of community building is intricately connected with a person's ability to make meaning out of experiences. Participants in the study noted several processes by which they acquired new knowledge: (a) knowledge through internal processes, (b) knowledge through modeling, (c) knowledge through experiences, (d) knowledge through acknowledgment and application. Acknowledging and applying knowledge were behaviors identified as risk-taking, communication and active listening, acceptance of diverse cultures and opinions, and building community relations. The study suggested further research in the effects of these methods compared to other learning methods, the effects of these methods on other types of groups, the effects of the leader's relationship to the group, and the long-term effects on group dynamics. digital.library.unt.edu/ark:/67531/metadc2230/

Penile plethysmography: Validation with a juvenile sex offending population.
Traditionally, juvenile sex offenders have been ignored in the literature. More recently the research has expanded particularly in the area of assessment and treatment. This study focused on the assessment of sexual arousal to deviant stimuli using the penile plethysmography (PPG) since it likely plays a significant role in juvenile sex offending behaviors. The goal of this study assessed its validity and reliability using Becker et al.'s set of PPG scenarios with a population of juvenile sex offenders. Significant differences were found between groups of (a) admitters versus partial admitters and (b) offenders with and without male victims. This study also examined the latent structure of the PPG results and found three dimensions: arousal to male stimuli, arousal to females and paraphilias, and arousal to non-sexual acts. These findings provide important implications for assessment of juvenile sex offenders and add to the clinical utility of PPG assessments. digital.library.unt.edu/ark:/67531/metadc9755/
The Pennsylvania Rifle: the Evolution of its Tactical Employment in the American Revolution
There are two opinions as to the effectiveness of the Pennsylvania Rifle during the Revolutionary War. On one hand it is alleged that the rifle was, at best, not particularly useful, and that its disadvantages outweighed its advantages. In contradiction to this we find that the British military appealed to London for rifles, and that the British government specified that there be a definite number of riflemen among the mercenaries they hired. Furthermore, according to Fortescue, the British military were forced to change their tactics, at least in part, because of the rifle. It is the purpose of this thesis to resolve this conflict by determining which of the two positions, if either ,is correct, or to determine the extent to which they may both be correct. digital.library.unt.edu/ark:/67531/metadc130537/
El Pensamiento de José Martí tergiversado como Ideología Política y de Lucha por la Revolución Cubana
The political ideologies that Martí envisioned of an America free from the inherited yoke of European ideals were taken by Fidel Castro as an anti-imperialist discourse. Therefore, Marti’s political vision on the power that the United States began to carry out at the end of the 19th century and the beginning of the 20th century was an excellent strategy to establish the anti-imperialist character of the Cuban revolution. Since 1961, Castro set Martí as the face of his Marxist-Leninist ideology to institute his anti-American philosophy; Castro created a myth of Marti’s persona, and converted him into the bastion of his political ideology. As a result, Castro distorted the revolutionary ideas of Marti’s. Castro proposed his ideas out of context and portrayed the incorrect idea of this great thinker and poet. Martí’s human ethic and love for the independence of Cuba placed Martí as a liberator of revolutionary and progressive ideas of his generation. Martí was not thought as a dictator and never was a man who lacked democratic values. The expressed analytical assimilation of Martí on his sociopolitical and economic juncture that was presented in America and Cuba was used to trace the political anti-imperialist propaganda by the dictatorial regime lead by Castro. This thesis will emphasize the persona of Jose Martí as a revolutionary, visionary and educator of his generation, then it will present the incorrect interpretation of Marti’s ideology by Fidel Castro, as an ideal to embark his revolution. Finally, the differences of his ideas in contrast to the political and social ideology of the Cuban revolution will be explained. digital.library.unt.edu/ark:/67531/metadc103328/

Peptide-based hidden Markov model for peptide fingerprint mapping.
Access: Use of this item is restricted to the UNT Community.
Peptide mass fingerprinting (PMF) was the first automated method for protein identification in proteomics, and it remains in common usage today because of its simplicity and the low equipment costs for generating fingerprints. However, one of the problems with PMF is its limited specificity and sensitivity in protein identification. Here I present a method that shows potential to significantly enhance the accuracy of peptide mass fingerprinting, using a machine learning approach based on a hidden Markov model (HMM). This method is applied to improve differentiation of real protein matches from those that occur by chance. The system was trained using 300 examples of combined real and false-positive protein identification results, and 10-fold cross-validation applied to assess model discrimination. The model can achieve 93% accuracy in distinguishing correct and real protein identification results versus false-positive matches. The receiver operating characteristic (ROC) curve area for the best model was 0.833. digital.library.unt.edu/ark:/67531/metadc4645/
Perceived attractiveness and personality attributes: A gender and racial analysis
Subjects rated 12 female body shapes with respect to their physical attractiveness, and the extent to which they would be expected to possess various personality characteristics. The shapes were varied using 3 levels of overall weight and 4 levels of body shapeliness. The sample was modified to control for socioeconomic factors and results are based on 297 undergraduates from Caucasian, African American, and Hispanic racial backgrounds. Loglinear analyses revealed that men and women, regardless of racial background, rated shapely underweight females as most physically attractive, sexy, and ideal for a woman, followed by normal weight figures of similar proportion. African Americans, women in particular, judged the shapely normal weight figures more favorably than the other subjects. Multidimensional scaling and subsequent frequency analyses showed that those figures judged as most attractive, sexy, and ideal were also expected to be fairly emotionally stable, and most successful and interpersonally competitive, but least faithful, kind, and family-oriented. Overweight female shapes, while rated as least physically attractive, sexy, and emotionally stable, were expected to be most family-oriented, kind, and faithful. Shapely normal weight figures were judged to be attractive and sexy, and were assumed to possess a moderate amount of the personality traits in question. The results suggest that Caucasian and Hispanic subjects prefer shapely underweight women, while African Americans, particularly women, find shapely underweight and shapely normal weight women to be physically appealing. African American women also rate shapely normal weight women favorably with respect to personality traits. This perceptual difference may help inoculate them from developing eating disturbances and account for the low prevalence rate of eating disorders in African Americans compared to women of other racial backgrounds. It is suggested that future research identify those beliefs, values or behaviors that seem to inoculate African American women from developing eating disorders. Once identified, mental health professionals may facilitate their development in those women who are likely to have eating problems. digital.library.unt.edu/ark:/67531/metadc2509/
Perceived attributes of diffusion of innovation theory as predictors of Internet adoption among faculty members of Imam Mohammed Bin Saud University.
The Internet is the most common communication and research tool worldwide. Perusal of the World Wide Web quickly reveals the variety of information available. Internet adoption can be considered the late 20th century's most important event. In academic environments today, Internet use among faculty members has been widely expanded, with professors now integrating Internet technology into classroom activities. Imam Muhammad Bin Saud Islamic University (IMSU) is a pioneering public university in Saudi Arabia. Until recently, some faculty members at IMSU were unable to access the Internet through the university. It is important to study the effects of this delay on faculty members regarding research and academic activities. This study identified the statistically significant differences in demographic characteristics of Internet adopters and non-adopters among faculty members at IMSU, examined whether faculty members' perceptions of the Internet affected adoption, determined if the university administration's decisions impacted faulty members' decisions to adopt the Internet, identified factors motivating faculty members to adopt the Internet, identified obstacles influencing faculty members' decisions to use the Internet, and determined whether innovation characteristics as perceived by faculty members predicted Internet adoption. Using Rogers' diffusion of innovation theory, the influence of eight attributes were examined regarding Internet adoption among IMSU faculty members. Multiple regression and chi-square techniques were conducted to analyze the data and answer research questions. Statistically significant differences were identified among Internet adopters and non-adopters regarding gender, age, academic rank, discipline, and English proficiency. The data revealed 54.7% of IMSU faulty members used the Internet for research and academic activities twice a month or less, indicating a low Internet adoption rate. Statistically significant differences were noted among adopters and non-adopters relative to income level and English proficiency. Multiple regression analysis showed that all attributes of innovation individually predicted Internet adoption. The combination of all attributes indicated the model could predict Internet adoption among faculty. digital.library.unt.edu/ark:/67531/metadc3710/
Perceived barriers to faculty participation in distance education at a 4-year university.
Access: Use of this item is restricted to the UNT Community.
The purpose of this study was to identify perceived barriers to faculty participation in distance education courses in a 4-year university. The literature review was divided into four general areas, each of which may act as a barrier to faculty participation; training, administrators, rewards/compensation, and faculty characteristics/demographics. The research population consisted of 570 faculty and 59 administrators from the eight UNT schools/colleges. Dr. Kristin Betts developed the survey instrument in 1998 for similar research conducted at the George Washington University. Analysis of the collected data revealed that there was no statistically significant relationship found between faculty characteristics and faculty participation in distance education. Faculty participants and administrators disagreed on which factors, from a list of 34 items, had motivated faculty to participate in distance education. Nonparticipants and administrators disagreed on which of the factors, if not available, would be barriers to faculty participation in distance education. Participants and nonparticipants disagreed regarding the level to which selected rewards and compensations had motivated faculty to participate, and the lack of which would inhibit faculty participation in distance education. Finally, 71% of the participants had participated or planned to participate in distance education training compared to only 33% of the nonparticipants. It is obvious that administrators and faculty do not place the same level of importance on motivational or inhibiting factors that may affect faculty participation in distance education. These results indicate that additional research should be accomplished to determine the basis for the disagreement among the three groups. digital.library.unt.edu/ark:/67531/metadc4263/
Perceived Change in Behavior Associated with Peer Feedback in Work Teams
Access: Use of this item is restricted to the UNT Community.
This study investigated if the use of a team feedback system resulted in peers perceiving a change in behavior. Personality variables such as conscientiousness, agreeableness, and extraversion were examined as possible moderators. Self-ratings and peer ratings were collected from 164 individuals through the use of the Center for Collaborative Organizations' Team Feedback System. Using polynomial regression, it was determined that time 1 peer ratings predicted behavior change and the combination of conscientiousness variables moderated peer perceived behavior change. digital.library.unt.edu/ark:/67531/metadc4815/
Perceived Effects of a Mid-length Study Abroad Program
The focus of the study was the University of Dallas’ Rome Program, a mid-length study abroad program on the university’s campus in Rome, Italy. The program is designed to provide participants with the opportunity to encounter firsthand Western tradition by integrating the core curriculum through classroom teachings and class excursions, thus solidifying the foundation of the participants’ undergraduate education. Beyond this purpose, the Rome Program does not operate from established goals and objectives for student experience. I consulted relevant research literature to construct a schema of domains of development appropriate to this qualitative study. These domains were intellectual development, global perspective, career development, and spiritual development. I interviewed 20 University of Dallas seniors who participated in the mid-length study abroad program between fall 2009 and spring 2011, using an extended, semi-structured interview protocol. The participants included 11 females and 9 males; 19 White and 1 Hispanic. The findings were supported by subsequent review by 4 of the interviewed students. I found generally strong but inconsistent support for student development in each of the domains. A number of sub-themes are reported. Through the interviews, an additional theme of personal development emerged and is reported. Although the findings generally support the conclusion that the Rome Program is successful, good education practice leads to a recommendation of more explicit setting of goals by higher education program planners and administrators. Such goal setting provides rationale for program construction, provides students with their own goal framework, and establishes a tangible framework for ongoing program evaluation. digital.library.unt.edu/ark:/67531/metadc115057/
Perceived features and similarity of images: An investigation into their relationships and a test of Tversky's contrast model.
The creation, storage, manipulation, and transmission of images have become less costly and more efficient. Consequently, the numbers of images and their users are growing rapidly. This poses challenges to those who organize and provide access to them. One of these challenges is similarity matching. Most current content-based image retrieval (CBIR) systems which can extract only low-level visual features such as color, shape, and texture, use similarity measures based on geometric models of similarity. However, most human similarity judgment data violate the metric axioms of these models. Tversky's (1977) contrast model, which defines similarity as a feature contrast task and equates the degree of similarity of two stimuli to a linear combination of their common and distinctive features, explains human similarity judgments much better than the geometric models. This study tested the contrast model as a conceptual framework to investigate the nature of the relationships between features and similarity of images as perceived by human judges. Data were collected from 150 participants who performed two tasks: an image description and a similarity judgment task. Qualitative methods (content analysis) and quantitative (correlational) methods were used to seek answers to four research questions related to the relationships between common and distinctive features and similarity judgments of images as well as measures of their common and distinctive features. Structural equation modeling, correlation analysis, and regression analysis confirmed the relationships between perceived features and similarity of objects hypothesized by Tversky (1977). Tversky's (1977) contrast model based upon a combination of two methods for measuring common and distinctive features, and two methods for measuring similarity produced statistically significant structural coefficients between the independent latent variables (common and distinctive features) and the dependent latent variable (similarity). This model fit the data well for a sample of 30 (435 pairs of) images and 150 participants (&#967;2 =16.97, df=10, p = .07508, RMSEA= .040, SRMR= .0205, GFI= .990, AGFI= .965). The goodness of fit indices showed the model did not significantly deviate from the actual sample data. This study is the first to test the contrast model in the context of information representation and retrieval. Results of the study are hoped to provide the foundations for future research that will attempt to further test the contrast model and assist designers of image organization and retrieval systems by pointing toward alternative document representations and similarity measures that more closely match human similarity judgments. digital.library.unt.edu/ark:/67531/metadc4749/
Perceived Racial Discrimination and Psychiatric Outcomes among Asian Americans
The present study related generational status, family dynamics, and perceptions of racial discrimination (PRD) to acute psychiatric outcomes among a nationally representative Asian American sample (N = 2095), using data from the National Latino and Asian American Study (NLAAS). High self-reports of PRD were correlated with endorsement of clinical depression and suicidality as predicted. Regression analyses suggested that high PRD, low family cohesion, and high family conflict served as significant predictors of poor mental health independently, but moderator hypotheses predicting the interaction of these factors were not supported. Clinical and research implications are provided. digital.library.unt.edu/ark:/67531/metadc12210/
Perceived Submaximal Leg Extension Forces of Young Adult Males
Access: Use of this item is restricted to the UNT Community.
The purpose was to examine actual force (AF) productions of males for accuracy during leg extensions when given a random desired force (DF) ranging from 10-90% of maximal force (MF). Thirty males ranging from 18 to 30 years of age (M = 21.99 + 3.04), who had no previous experience with the test equipment, went through 9 randomly ordered submaximal efforts followed by a maximal effort. Correlations between AF and DF were high (r > .79) and test-retest was consistent between AF (r = .87) and MF (r = .90). Participants consistently undershot DF on both test and retest from 20-90% and overshot DF only at 10%. Power functions revealed exponents of less than 1, indicating that AF grows slower then DF for both test .70 (.95 CI = .63 - .77) and retest .66 (.95 CI = .60 - .73). The results replicate a prior study by Jackson, Martin, Koziris, Ludtke, and Dishman (2001) that used incremental rather than random increases in DF. digital.library.unt.edu/ark:/67531/metadc2840/
The Perceived Value Among Employers of College Study Abroad for Engineers
Engineering graduates of the twenty-first century must be worldly and understand how to work with professionals from many cultures on projects that cross international boundaries. Increasingly, employers are finding that prospective employees who have studied abroad make better, more rounded candidates than those who have no life experience outside of their home region. The objective of this study was to determine whether engineering students who participate in a major-specific, study abroad experience are more desirable as candidates for employment than those who only study at their home institution. This descriptive study surveyed the membership of the combined Industrial Advisory Boards of the University of North Texas College of Engineering (n=90) which is a focused group of skilled managers and directors that represent various businesses, industries and organizations. The survey yielded a 58% response rate. The evaluation was validated by a survey that searched for a perceptual trend among representatives from business and industry who are in a hiring capacity for engineering graduates, evaluating a major-specific study abroad experience as part of a graduate’s employability and career growth. Statistical Analysis was made on Companies whose scope of business is domestic and international comparing the perceived value of study abroad as a characteristic for hiring new engineers, as well as comparing the perceived value of foreign study or work experience on the career development of engineers. These tests indicated that at the 0.05 level there was no statistical significance in the findings. Additional analysis was made on groups of employees that either had foreign experience (work or study) and those that did not. These tests indicated that there was no statistical significance in the findings. Analysis of the data indicates that although having a major specific study abroad experience may not be important at the entry level, it becomes more important as an engineer progresses into mid-career. It could also indicate change in the business climate and a growing need for global awareness. Additional observations show that other co-curricular activities, such as internships and grades weigh more in the hiring of a new engineering graduate. digital.library.unt.edu/ark:/67531/metadc149606/
Perceived value of journals for academic prestige, general reading and classroom use: A study of journals in educational and instructional technology.
Conducting research, evaluating research, and publishing scholarly works all play an extremely prominent role for university faculty members. Tenure and promotion decisions are greatly influenced by the perceived value of publications as viewed by members of faculty evaluation committees. Faculty members seeking tenure may be limited to publishing in a limited group of journals perceived to be valuable by members of an academic committee. This study attempted to determine the value of various kinds of periodicals (journals, magazines, and e-journals), based on three principal criteria, as perceived by professionals (university faculty, K-12 practitioners, and corporate trainers) in the educational/instructional technology (E/IT) field. The criteria for journal evaluation were Academic Prestige, General Reading, and Classroom Use. The perceived value of journals based on each criterion was compared to determine any significant differences. Members of the Association for Educational Communications and Technology (AECT) were asked to rate 30 journals in the E/IT field using the three criteria. Statistically significant differences were found among ratings in 63% of the journals. The statistical analyses indicated that differences in the perceived value of journals among E/IT professionals across the three criteria (Academic Prestige, General Reading, and Classroom Use) were statistically significant. It is also noted that refereed journals were rated higher than nonrefereed journals for the Academic Prestige criterion. Survey respondents indicated that individual journals were not valued for the same reasons. This finding implies that the formation of any equitable measure for determining the value of faculty members' journal article publications would be best if based on definable criteria determined by colleagues. Lists of valued journals for each area of faculty assessment would provide standards of excellence both inside and outside the E/IT field for those who serve on tenure and promotion committees in educational institutions. digital.library.unt.edu/ark:/67531/metadc4233/
Perceiving matter in notes on space, undated (log 3) by André du Bouchet, Fontfroide-le-Haut, Fata Morgana, 2000
This study of the graphic field in notes on space, undated (log 3) focuses on how the white emptiness of a page plays a structural role in the articulation of dissociated fragments of notes. According to the criteria of three theorists (Genette, Lapacherie, Baetens), the distinction between non-linear and tabular proves to be non-exclusive in this particular work. Ostensibly, this non-figurative writing instigates interactive contemplation and lends itself to multiple entries, like an object one contemplates from every possible visual perspective without ever constructing a representation or image. The poetic form that du Bouchet explores renders perceptible the latent materiality of all text. digital.library.unt.edu/ark:/67531/metadc4389/
The perception of English language arts teachers about instructional changes following the implementation of the Texas Assessment of Knowledge and Skills test.
Accountability in education has been expanding for the past twenty years. As standards for curricular areas continued to develop, educational shareholders desired a way to measure student achievement contextualized by the established standards. Since 1964, policies expanded federal involvement with education, and with the No Child Left Behind Act in 2001, high-stakes testing became a significant part of public education. In Texas, testing transitioned in 2003 to the Texas Assessment of Knowledge and Skill (TAKS) test, an assessment that determines grade advancement for students, ratings for school districts, and additional compensation for some teachers. Along with the increasing expectations for student achievement, the need for effective instruction also increases. This dissertation studies how English language arts (ELA) teachers in four North Texas suburban high schools perceive instructional change following the implementation of TAKS. One hundred twenty-one teachers (n=121) were surveyed using an instrument broken into seven categories: student-centered instruction, student interest, instructional communication, time, classroom environment, teacher knowledge, and assessment. Participants were separated into two groups, teachers with one to six years of experience with a district or seven or more years with a district. Using a rating scale for each statement on the survey instrument, participants indicated the direction and magnitude of change or indicated no change occurred. When comparing an overall average frequency percentage for each possible rating for each category, the two highest percentages for both surveyed groups indicated no instructional change since the implementation of TAKS. However, when considering specific statements about professional growth and instructor knowledge, both groups were likely to rate a change as positive. Whereas, if the statement suggested instructional areas constricted by time, participants for both groups were likely to rate a change as negative. Additionally, an ANOVA indicated no significant difference between either of the participating groups. digital.library.unt.edu/ark:/67531/metadc12134/
Perception of Foreign Accented Speech: the Roles of Familiarity and Linguistic Training
This paper seeks to address the issue by examining two factors that potentially affect a listener’s perception of foreign accented speech: degree of familiarity (as acquired through a work or personal environment) and amount of ESL or linguistic training. Speech samples were recorded from 18 international students from Hispanic, Asian, and Middle-eastern backgrounds and across all proficiency levels as designated by their academic English program. Six native English speakers were also recorded to serve as a basis for comparison. Listeners were drawn from two pools: people with ESL and/or linguistic training (n=42) and laypersons with no such specialist training (n=36). After completing a background questionnaire to assess familiarity with foreign accented speech, each listener rated all 24 speech samples on the dimensions of comprehensibility, degree of accent, and communicative ability. Results indicate that participants with ESL/linguistic training rate foreign accented speech more positively on all three dimensions than laypersons with no such training. Additionally, degree of familiarity with foreign accented speech is positively correlated with how participants rated the accented speech samples. a number of highly significant interactions between these and other factors including sex of the speaker, proficiency level of the speaker, and L1 family of the speaker were found as well. digital.library.unt.edu/ark:/67531/metadc115151/
Perceptions and attributions of child, spousal, and elder abuse.
Although researchers have studied perceptions regarding sexually abused children, little was known about how other types of abusive events were perceived. This study examined 480 college students' abuse history and perceptions of child, spousal, and elder abuse by varying the respondent, victim, and perpetrator genders. Physical abuse, psychological abuse, and neglect were investigated. Perceptions of abusiveness, seriousness, harm, and responsibility were examined, along with the extent of identification with the victims/perpetrators. Participants viewed spousal abuse as less serious and harmful than other abuse types, especially when perpetrated against a male or by a female. Although able to recognize psychological abuse, students did not fully understand what other abuse types entailed. Individuals also showed a considerable amount of blame toward victims. Results further demonstrated important findings about how ethnic identity/orientation, religious affiliation, and history of abuse related to perceptions of abusive events. digital.library.unt.edu/ark:/67531/metadc4643/
Perceptions of agency: Beliefs of four adolescent girls in high school as revealed through literature discussions.
Published research suggests that cultural practices and institutional structures influence adolescent girls' engagement and achievement in school. This study was an attempt to further investigate that claim by describing the perceptions of agency held by four adolescent girls in high school. Members of the same English class, the girls volunteered to participate in three lunchtime meetings to discuss Evelyn Coleman's (2001) Born In Sin. Analysis of classroom observations, transcripts of audio recordings of the book discussions, and individual interviews yielded a more precise definition of agency than those used in previous research, including a view of agency as dialogic. In addition, four major themes describe these girls' agentic moves: (1) a temporal orientation, which connects the past, present, and future; (2) responsibility for positive and negative events; (3) strategic decision making; (4) negotiating with people in power. Implications of this study inform both teaching decisions and future research related to adolescent girls. digital.library.unt.edu/ark:/67531/metadc9111/
Perceptions of assurance service services performed by certified public accountants: Accounting education assessment applications
The overall purpose of this study was to examine how Certified Public Accountants (CPAs) perceive the potential use of assurance services to assess quality in accounting education programs. Survey questionnaires were mailed to a random sample of 250 CPAs in the north central Texas area. The questionnaire was designed to obtain demographic information and information relating to the respondents' perceptions of quality assessment of accounting education programs. An analysis of the results of this study suggest the following: CPAs consider (1) certain established criteria, such as SAT scores and faculty-to-student ratios, as effective measures for assessing quality attributes in accounting education programs and (2) traditional measures currently used for quality assessment in accounting education programs as only moderately effective by CPAs. CPAs are apparently seeking increased involvement with accounting education quality assessment and formulation of educational standards. They view the potential application of assurance services to accounting education quality as a way to offer a wider range of services to the public. CPAs perceive assurance services as a type of quality assessment that can be used to complement, but not replace, some of the more effective traditional methods, and as a way of enhancing the quality assessment process for accounting education. digital.library.unt.edu/ark:/67531/metadc2912/
Perceptions of Commitment
This study investigated differences in level of commitment between married and non-married individuals, effects of demographic variables by age, gender, parenting status, and ethnicity, and determines participant's awareness of and participation in the Oklahoma Marriage Initiative (OMI) were investigated. Students from a rural Oklahoma junior college completed the Perceptions of Commitment survey during spring 2004. Responses related to levels of commitment, social exchange theory, expectations, and communication were collected. T-test analysis revealed no differences in level of commitment for any of the variables investigated. Data revealed the majority of participants were unaware of OMI and had never attended a program and do not plan to in the future. Implications of this research may be useful to future investigators who are interested in the Perceptions of Commitment survey and those focusing on marriage education programs to meet the needs of targeted audiences. digital.library.unt.edu/ark:/67531/metadc4547/
