A Personal Documenation System for Scholars: A Tool for Thinking
This exploratory research focused on a problem stated years ago by Vannevar Bush: "The problem is how creative men think, and what can be done to help them think." The study explored the scholarly work process and the use of computer tools to augment thinking. Based on a review of several related literatures, a framework of 7 major categories and 28 subcategories of scholarly thinking was proposed. The literature was used to predict problems scholars have in organizing their information, potential solutions, and specific computer tool features to augment scholarly thinking. Info Select, a personal information manager with most of these features (text and outline processing, sophisticated searching and organizing), was chosen as a potential tool for thinking. The study looked at how six scholars (faculty and doctoral students in social science fields at three universities) organized information using Info Select as a personal documentation system for scholarly work. These multiple case studies involved four in-depth, focused interviews, written evaluations, direct observation, and analysis of computer logs and files collected over a 3- to 6-month period. A content analysis of interviews and journals supported the proposed AfFORD-W taxonomy: Scholarly work activities consisted of Adding, Filing, Finding, Organizing, Reminding, and Displaying information to produce a Written product. Very few activities fell outside this framework, and activities were distributed evenly across all categories. Problems, needs, and likes mentioned by scholars, however, clustered mainly in the filing, finding, and organizing categories. All problems were related to human memory. Both predictions and research findings imply a need for tools that support information storage and retrieval in personal documentation systems, for references and notes, with fast and easy input of source material. A computer tool for thinking should support categorizing and organizing, reorganizing and transporting information. It should provide a simple search engine and support rapid scanning. The research implies the need for tools that provide better affordances for scholarly thinking activities. digital.library.unt.edu/ark:/67531/metadc2258/
A Personal Expression
The problem involves developing a method that leaves conventional form and form making and moves toward a spontaneous and intuitive approach. The thesis is organized into 3 chapters. The first chapter includes an introduction, statement of the problem and methodology. The second chapter describes the work in eight movements. The third chapter answers questions posed by the problem and includes a summary and conclusion. The findings are that a spontaneous, impulsive, and intuitive approach to the medium, clay, is a productive and artistic method. The medium is responsive and telling of the method and art is produced. digital.library.unt.edu/ark:/67531/metadc4477/

Personal Passions and Carthusian Influences Evident in Rogier Van Der Weyden's Crucified Christ between the Virgin and Saint John and Diptych of the Crucifixion
This thesis examines Rogier Van Der Weyden's two unique fifteenth century Crucifixions, The Crucified Christ Between the Virgin and Saint John and The Diptych of the Crucifixion, in light of Carthusian beliefs, practices and relevant devotional texts. The specific text used to support this examination is the Vita Christi by Ludolph of Saxony, which in part deals specifically with the Hours of the Passion. Ludolph's text is given visual form in Rogier's paintings and supports the assertion that Rogier and Ludolph were connected by a shared belief and worldview. Key aspects of Rogier's life, supported by original documentation- familial ties, associates, patrons, use of finances, and his close involvement with the Carthusians-- support this assertion. Other models of connections of belief, evidenced through artist's work, are corroborated in the work of Grunewald, Sluter and Durer. digital.library.unt.edu/ark:/67531/metadc5245/
Personal Properties: Stage Props and Self-Expression in British Drama, 1600-1707
Access: Use of this item is restricted to the UNT Community.
This dissertation examines the role of stage properties-props, slangily-in the construction and expression of characters' identities. Through readings of both canonical and non-canonical drama written between 1600 and 1707-for example, Thomas Middleton's The Revenger's Tragedy (1607), Edward Ravenscroft's adaptation of Titus Andronicus (1678), Aphra Behn's The Rover (1677), and William Wycherley's The Plain Dealer (1677)-I demonstrate how props mediate relationships between people. The control of a character's props often accords a person control of the character to whom the props belong. Props consequently make visual the relationships of power and subjugation that exist among characters. The severed body parts, bodies, miniature portraits, and containers of these plays are the mechanisms by which characters attempt to differentiate themselves from others. The characters deploy objects as proof of their identities-for example, when the women in Behn's Rover circulate miniatures of themselves-yet other characters must also interpret these objects. The props, and therefore the characters' identities, are at all times vulnerable to misinterpretation. Much as the props' meanings are often disputed, so too are characters' private identities often at odds with their public personae. The boundaries of selfhood that the characters wish to protect are made vulnerable by the objects that they use to shore up those boundaries. When read in relation to the characters who move them, props reveal the negotiated process of individuation. In doing so, they emphasize the correlation between extrinsic and intrinsic worth. They are a measure of how well characters perform gender and class rolls, thereby demonstrating the importance of external signifiers in the legitimation of England's subjects, even as they expose "legitimacy" as a social construction. digital.library.unt.edu/ark:/67531/metadc12081/

Personal stories go worldwide: the ritual of storytelling through Weblogs.
The once private traditional written diary is shifting to an electronic storytelling tradition. Online diaries or weblogs are a growing phenomenon that scholars have ignored until recently. This qualitative project uses narrative and rhetorical analysis to focus on storytelling themes in weblogs, rituals in storytelling and the similarities and differences from traditional written diaries. In this study, 30 weblogs were chosen from three web domains: livejournal.com, blogger.com and diarest.net. The findings show that weblogs are filled with rich storytelling that emulates many qualities of traditional diaries. In general, weblogs authors are communicating stories online to an interactive mass audience and forming new rituals in a new electronic forum. digital.library.unt.edu/ark:/67531/metadc4601/
Personalities and Pipelines: Exploring the Role of Personality in Student Self-selection Into Stem Majors
Despite all the national efforts to increase STEM enrollment in the United States, the gap between the U.S. and other developed countries in terms of STEM graduates has widened over the last 20 years. Researchers have studied factors such as gender, race, high school GPA, and the student’s socioeconomic status for their impact on STEM enrollment. This study offers another possible explanation of why students might choose, or not choose, to enroll in STEM majors by examining the relationship between personality and STEM enrollment. the sample included 2,745 respondents to the 2008 Cooperative Institutional Research Program freshman survey at a large research university in the southwestern United States. Factor analysis was used to create four personality scales, based on John Holland’s theory of personality types, with items selected from the survey. Logistic regression was utilized to answer three research questions: Are students classified as a strong investigative personality type more likely to enroll in STEM majors than students classified as a weak investigative personality type? Are there differences in their likelihood to enroll in STEM majors among students of investigative-social, investigative-artistic, and investigative-enterprising personality types? What effect does personality have on students’ self-selection into a biological versus a physical STEM major? Results suggested that students with a combined investigative and social personality were more likely to enroll in STEM majors whereas students with a combined investigative and artistic personality were less likely to do so. Additionally, STEM students with an enterprising personality were more likely to choose a biological STEM major than a physical STEM major. These results should benefit educators and policy makers who seek to strengthen the pipeline into STEM fields. digital.library.unt.edu/ark:/67531/metadc115158/

Personality and Decision Behavior
The purpose of this study is to investigate the relationship between personality and certain characteristics of decision-making behavior in a modified two-choice probability learning situation. More specifically, this study addresses itself to the following questions: (1) Can personality correlates of the decision-making process be demonstrated? (2) Are personality factors related to individual differences in maximizing tendency, risk-taking, and decisiveness? (3) If such relationships, exist, who do they fit into the framework of existing decision-making theory? digital.library.unt.edu/ark:/67531/metadc163957/
Personality and Rater Leniency: Comparison of Broad and Narrow Measures of Conscientiousness and Agreeableness
Performance appraisal ratings provide the basis for numerous employment decisions, including retention, promotion, and salary increases. Thus, understanding the factors affecting the accuracy of these ratings is important to organizations and employees. Leniency, one rater error, is a tendency to assign higher ratings in appraisal than is warranted by actual performance. The proposed study examined how personality factors Agreeableness and Conscientiousness relate to rater leniency. The ability of narrower facets of personality to account for more variance in rater leniency than will the broad factors was also examined. The study used undergraduates' (n = 226) evaluations of instructor performance to test the study's hypotheses. In addition to personality variables, students' social desirability tendency and attitudes toward instructor were predicted to be related to rater leniency. Partial support for the study's hypotheses were found. The Agreeableness factor and three of the corresponding facets (Trust, Altruism and Tender-Mindedness) were positively related to rater leniency as predicted. The hypotheses that the Conscientiousness factor and three of the corresponding facets (Order, Dutifulness, and Deliberation) would be negatively related to rater leniency were not supported. In the current sample the single narrow facet Altruism accounted for more variance in rater leniency than the broad Agreeableness factor. While social desirability did not account for a significant amount of variance in rater leniency, attitude toward instructor was found to have a significant positive relationship accounting for the largest amount of variance in rater leniency. digital.library.unt.edu/ark:/67531/metadc3668/
Personality and the prediction of outcome following rehabilitation in persons with acquired brain injuries: The Millon Behavioral Medicine Diagnostic (MBMD).
Neuropsychological rehabilitation following acquired brain injury is increasingly recognized as essential with the advancements in research evidence of its effectiveness, particularly as current estimates of disability following the most common forms of brain injury (traumatic brain injury and cerebrovascular accident) are so high. Improvements in predictive capabilities of researchers and clinicians are paramount in designing effective interventions. As many variables associated with outcome following brain injury are not controllable (e.g. severity of the injury, age, education), it is essential that rehabilitation programs design interventions to target those variables that are susceptible to amelioration. While personality factors have been shown to affect outcome in other medical illnesses, only a few studies have examined the influence of personality on outcome following neurorehabilitation for acquired brain injury. The results of these studies have been mixed. This study used the Millon Behavioral Medicine Diagnostic (MBMD) to predict outcome as measured by the Mayo-Portland Adaptability Index (MPAI-4) following brain injury rehabilitation in a heterogeneous sample of persons with acquired brain injuries (N = 50). It was hypothesized that specific coping styles scales from the MBMD (Introversive, Dejected, Oppositional), which are based on Millon's personality system, would predict outcome. Results indicated that both the Introversive and Oppositional coping styles scales accounted for significant amounts of variance in outcome beyond that accounted for by the severity of the injury alone (p < .001). In both cases, individuals with mild/moderate-moderate/severe limitations following completion of the rehabilitation program had significantly higher scores on the Introversive and Oppositional coping compared to individuals with more successful outcomes. The hypothesis that a dejected coping style would predict outcome was not supported. Implications for rehabilitation are discussed in the context of Millon's personality system. digital.library.unt.edu/ark:/67531/metadc9121/
Personality characteristics of Counselor Education graduate students as measured by the Myers-Briggs Type Indicator and the Bem Sex Role Inventory
Access: Use of this item is restricted to the UNT Community.
This study was designed to investigate the correlation of the variables of gender, Myers-Briggs Type Indicator (MBTI) personality preferences, and androgyny as measured by the Bem Sex Role Inventory (BSRI) in Counselor Education graduate students. Instruments were administered to Counselor Education graduate students at nine institutions in five national regions. A total of 172 participants (18 males and 154 females) who were enrolled in Master's level theories courses or practicum courses completed a student information sheet, informed consent, MBTI, and BSRI. Instruments were hand scored and chi-square test was used to determine significance of the hypotheses; the saturated model of log linear analysis was the statistic used for the research question. As predicted, of the sixteen MBTI types, the most common for Counselor Education graduate students emerged as ENFP: extraversion, intuition, feeling, and perception. Additionally, this MBTI type was found to be significantly more common among the population of Counselor Education graduate students than is found among the general population. The expectation that more male Counselor Education graduate students would score higher on the androgyny scale of the BSRI was unsupported; low sample size for male Counselor Education graduate students prevented use of chi-square; however, it was apparent through the use of the statistic of raw frequencies that males clustered around every other category except androgyny. The hypothesis that more female Counselor Education graduate students would score higher on the feminine scale was also unsupported, as equal distribution of the females occurred within all four categories of the BSRI. It was hypothesized that males with a sensing and thinking preference on the MBTI would tend toward the masculine dimension of the BSRI more than males with an intuitive and feeling preference. This was unsupported as well. Female Counselor Education graduate students with an intuitive and feeling preference did, however, demonstrate a greater tendency toward the feminine classification on the BSRI than did females with a sensing and thinking preference, so that this hypothesis was retained. No significant relationship was found between the variables of MBTI type, BSRI classification, and gender. digital.library.unt.edu/ark:/67531/metadc2263/

Personality Correlates of Anorexia Nervosa in a Nonclinical Sample
The purpose of this study was to examine the relationship between anorexia nervosa and several personality traits. Past research in this area has been contradictory for several reasons. Sociocultural theories have described the media's role in promoting eating disorders by portraying a thin body-type as the ideal. However, they have neglected to describe the personality ideal which our society promotes in women. It is proposed here that anorexics incorporate and oppose this ideal. Therefore, the anorexic personality is one filled with conflict. digital.library.unt.edu/ark:/67531/metadc279090/
Personality Correlates of Eating Disorder Symptomatology in a Nonclinical Sample of Female Undergraduates
Access: Use of this item is restricted to the UNT Community.
Research indicates the existence of an eating disorder continuum. The two-component model of disordered eating suggests that certain personality traits may increase an individual's vulnerability to develop more severe variants of disordered eating symptomatology. The present study investigates pre-clinical elevations on a measure of personality based on the Five-Factor Model (FFM) and pre-clinical elevations on a measure of eating disorder symptomatology in a sample of nonclinical undergraduates. The personality dimensions Neuroticism, Extraversion, and Agreeableness accounted for 7% of the variability in Body Dissatisfaction. Subcomponents comprising the personality dimensions of the FFM as determined by Saucier (1998) (see Appendix A) were analyzed. The Self-Reproach and Intellectual Interests subcomponents were the strongest predictors of Drive for Thinness and Body Dissatisfaction. The subcomponent Sociability was the strongest predictor of Bulimia. Findings present implications for prevention and treatment interventions. Longitudinal studies are needed to determine the temporal directionality of personality and disturbed eating. digital.library.unt.edu/ark:/67531/metadc5518/

Personality Type Preferences of Juvenile Delinquents
The purpose of this study was to identify and explore personality characteristics of juvenile delinquents, to compare those characteristics with those of the general population, and determine if there are significant differences, as measured by the Myers-Briggs Type Indicator (MBTI), between the personality characteristics of juvenile delinquents and the general population. Juvenile delinquents who were adjudicated into a Texas Youth Commission facility in North Texas were subjects for this study. Participants included 186 males who ranged in age from 14 years to 20 years. Statistical analyses were performed for each of the research questions. When comparing MBTI scores of juvenile delinquents to the general population, significant differences were found on the dichotomous scales, temperaments, function pairs, and types. All type preferences are represented within the juvenile delinquent population. The MBTI can be useful in responding to the education and rehabilitation needs of juvenile delinquents. Knowledge of personality type can help caregivers meet the needs of juvenile delinquents. Understanding personality type preference can serve to provide a deeper understanding of the behaviors that lead to adjudication of juvenile delinquents. A discovery of the types of adolescents who are adjudicated could lead to preventive measures, early detection, and early intervention for students at risk of becoming juvenile delinquents. digital.library.unt.edu/ark:/67531/metadc2653/

Personnel Preparation in Special Education: An Exploration of Autism Spectrum Disorders Programmatic Changes in Institutions of Higher Education Teacher Training Programs
Programmatic change related to autism spectrum disorders (ASD) training in special education teacher education programs across the U.S. and institutional variables that influenced change were examined. Variables included institutions’ current coverage of autism content in coursework and institution enrollment. One faculty member from each identified institution was invited to participate in the study. Data were collected from 136 special education faculty using an exploratory survey instrument, the National Survey on ASD Preparation in Undergraduate Special Education Teacher Training Programs (NSAP). This study was designed around themes which emerged from empirical and pragmatic research findings conceptualizing prevalent issues in personnel preparation for ASD including critical knowledge and skills needed by teachers to effectively serve students with ASD. Results indicated a significant number of programmatic changes (66%) remain to be implemented in undergraduate special education programs at institutions participating in the study. digital.library.unt.edu/ark:/67531/metadc84239/

Perturbation of renewal processes
Renewal theory began development in the early 1940s, as the need for it in the industrial engineering sub-discipline operations research had risen. In time, the theory found applications in many stochastic processes. In this thesis I investigated the effect of seasonal effects on Poisson and non-Poisson renewal processes in the form of perturbations. It was determined that the statistical analysis methods developed at UNT Center for Nonlinear Science can be used to detect the effects of seasonality on the data obtained from Poisson/non-Poisson renewal systems. It is proved that a perturbed Poisson process can serve as a paradigmatic model for a case where seasonality is correlated to the noise and that diffusion entropy method can be utilized in revealing this relation. A renewal model making a connection with the stochastic resonance phenomena is used to analyze a previous neurological experiment, and it was shown that under the effect of a nonlinear perturbation, a non-Poisson system statistics may make a transition and end up in the of Poisson basin of statistics. I determine that nonlinear perturbation of the power index for a complex system will lead to a change in the complexity characteristics of the system, i.e., the system will reach a new form of complexity. digital.library.unt.edu/ark:/67531/metadc6140/

Peter Lieberson's First Piano Concerto: A Buddhist-inspired poetic vision realized through twelve-tone language, other contemporary compositional techniques, together with three recitals of works by Bach, Chopin, Mozart, Albéniz, Grieg, Ginastera and Paderecki
Access: Use of this item is restricted to the UNT Community.
The main objective of this document is to explore the life and spiritual convictions of composer Peter Lieberson, and the creation of his Piano Concerto. Lieberson is a sought after composer who has won many awards and commissions. His works have been premiered and performed by some of the best musical artists of the late twentieth- and early twenty-first-century, such as Peter Serkin, Emmanuel Ax, Yo-Yo Ma, and Pierre Boulez. This study is divided into six chapters. After the Introduction, a biographical summary of Peter Lieberson's life, his spiritual beliefs and compositional style is presented. Chapter II contains background information on the Piano Concerto, along with biographical sketches of Peter Serkin, for whom the work was written, and Seiji Ozawa, music director of the Boston Symphony Orchestra and conductor of both the premier performance and Serkin's recording of the piece. Chapter III is a selective survey of the compositional techniques used in Lieberson's Concerto, in terms of the application of twelve-tone theory and the resulting octatonic, pentatonic, and whole-tone scales. Chapter IV introduces a general overview of the influence of Buddhism as a source of inspiration in the Piano Concerto. Chapter V examines aspects of performance practice issues. Chapter VI provides conclusions. The aim of this study is to further establish Peter Lieberson's stature as an important modern American composer. It is hoped that this study will encourage further research and interest in his works. digital.library.unt.edu/ark:/67531/metadc3175/
Pets and the level of loneliness in community dwelling older adults.
Loneliness is a significant problem for older adults and can lead to negative health and social outcomes. Having a companion pet is beginning to be recognized as a way loneliness can be reduced for older persons. The purpose of this descriptive study was to determine the effect of pets on the level of loneliness in persons 60 years old or older who live alone and independently in a large metropolitan community in the North Central Texas area. Using a non-random snowball sample of older individuals (N = 252), who met the study criteria, each subject was administered the researcher-developed demographic data survey instrument containing the following variables: (a) pets - having a pet/wanting a pet, (b) age, (c) gender, (d) marital status, (e) living alone, (f) losses within the last six months, (g) interactions with family members, (h) interactions with others outside of the family, (i) highest educational level achieved, (j) employment or volunteer involvement in the community, (k) religious participation, and (l) self perceived health status. The UCLA Loneliness Scale Version 3 was used to obtain the loneliness scores. Prediction of loneliness and relationship with the independent variables was tested using frequency, correlation, analysis of variance (ANOVA), and multivariate analysis using ordinary least-squares (OLS) regression analysis. The findings from this study showed that those older adults living alone who did not have a pet but would like to have a companion pet had higher levels of loneliness (p<0.05). Other findings suggested that older adults' loneliness was less if they had moderate religious participation and interactions with others (p< 0.05). Future studies are needed to examine the effects that pets have on feelings of loneliness and the ability of older individuals to cope effectively with those feelings. digital.library.unt.edu/ark:/67531/metadc5493/
The Pettis Integral and Operator Theory
Access: Use of this item is restricted to the UNT Community.
Let (Ω, Σ, µ) be a finite measure space and X, a Banach space with continuous dual X*. A scalarly measurable function f: Ω→X is Dunford integrable if for each x* X*, x*f L1(µ). Define the operator Tf. X* → L1(µ) by T(x*) = x*f. Then f is Pettis integrable if and only if this operator is weak*-to-weak continuous. This paper begins with an overview of this function. Work by Robert Huff and Gunnar Stefansson on the operator Tf motivates much of this paper. Conditions that make Tf weak*-to-weak continuous are generalized to weak*-to­weak continuous operators on dual spaces. For instance, if Tf is weakly compact and if there exists a separable subspace D X such that for each x* X*, x*f = x*fχDµ-a.e, then f is Pettis integrable. This nation is generalized to bounded operators T: X* → Y. To say that T is determined by D means that if x*| D = 0, then T (x*) = 0. Determining subspaces are used to help prove certain facts about operators on dual spaces. Attention is given to finding determining subspaces far a given T: X* → Y. The kernel of T and the adjoint T* of T are used to construct determining subspaces for T. For example, if T*(Y*) ∩ X is weak* dense in T*(Y*), then T is determined by T*(Y*) ∩ X. Also if ker(T) is weak* closed in X*, then the annihilator of ker(T) (in X) is the unique minimal determining subspace for T. digital.library.unt.edu/ark:/67531/metadc2844/
The Phantom Menace: the F-4 in Air Combat in Vietnam
The F-4 Phantom II was the United States' primary air superiority fighter aircraft during the Vietnam War. This airplane epitomized American airpower doctrine during the early Cold War, which diminished the role of air-to-air combat and the air superiority mission. As a result, the F-4 struggled against the Soviet MiG fighters used by the North Vietnamese Air Force. By the end of the Rolling Thunder bombing campaign in 1968, the Phantom traded kills with MiGs at a nearly one-to-one ratio, the worst air combat performance in American history. The aircraft also regularly failed to protect American bombing formations from MiG attacks. A bombing halt from 1968 to 1972 provided a chance for American planners to evaluate their performance and make changes. The Navy began training pilots specifically for air combat, creating the Navy Fighter Weapons School known as "Top Gun" for this purpose. The Air Force instead focused on technological innovation and upgrades to their equipment. The resumption of bombing and air combat in the 1972 Linebacker campaigns proved that the Navy's training practices were effective, while the Air Force's technology changes were not, with kill ratios becoming worse. However, the last three months of the campaign introduced an American ground radar system that proved more effective than Top Gun in improving air-to-air combat performance. By the end of the Vietnam War, the Air Force and Navy overcame the inherent problems with the Phantom, which were mostly of their own making. digital.library.unt.edu/ark:/67531/metadc283785/
Phase Separation and Second Phase Precipitation in Beta Titanium Alloys
The current understanding of the atomic scale phenomenon associated with the influence of beta phase instabilities on the evolution of microstructure in titanium alloys is limited due to their complex nature. Such beta phase instabilities include phase separation and precipitation of nano-scale omega and alpha phases in the beta matrix. The initial part of the present study focuses on omega precipitation within the beta matrix of model binary titanium molybdenum (Ti-Mo) alloys. Direct atomic scale observation of pre-transition omega-like embryos in quenched alloys, using aberration-corrected high resolution scanning transmission electron microscopy and atom probe tomography (APT) was compared and contrasted with the results of first principles computations performed using the Vienna ab initio simulation package (VASP) to present a novel mechanism of these special class of phase transformation. Thereafter the beta phase separation and subsequent alpha phase nucleation in a Ti-Mo-Al ternary alloy was investigated by coupling in-situ high energy synchrotron x-ray diffraction with ex-situ characterization studies performed using aberration corrected transmission electron microscopy and APT to develop a deeper understanding of the mechanism of transformation. Subsequently the formation of the omega phase in the presence of simultaneous development of compositional phase separation within the beta matrix phase of a Ti-10V-6Cu (wt%) alloy during continuous cooling has been investigated using a combination of transmission electron microscopy and atom probe tomography. The results of these investigations provided novel insights into the mechanisms of solid-state transformations in metallic systems by capturing the earliest stages of nucleation at atomic to near atomic spatial and compositional resolution. digital.library.unt.edu/ark:/67531/metadc67975/
