An Analysis of the Emotional Intelligence and Personality of Principals Leading Professional Learning Communities
The purpose of this study was to investigate the relationship between a principal's emotional intelligence and personality and his or her ability to implement and develop professional learning communities within the school. The Professional Learning Community Assessment (PLCA) was administered to principals and teachers in 13 schools in Texas ranging from elementary to high school. Based on the strength of the PLCA scores, two elementary schools were selected to participate in case study research. The principals of these two campuses were administered an emotional intelligence instrument (MSCEIT), a personality instrument (DiSC), and were interviewed along with three of their teachers. The findings indicate that both of these principals scored high in the Influential and Conscientiousness subscales and low in the Dominance subscale. The principals also possessed either near-average or above-average emotional intelligence with both principals scoring particularly strong in the Strategic subscale.

General Nathan Twining and the Fifteenth Air Force in World War II
General Nathan F. Twining distinguished himself in leading the American Fifteenth Air Force during the last full year of World War II in the European Theatre. Drawing on the leadership qualities he had already shown in combat in the Pacific Theatre, he was the only USAAF leader who commanded three separate air forces during World War II. His command of the Fifteenth Air Force gave him his biggest, longest lasting, and most challenging experience of the war, which would be the foundation for the reputation that eventually would win him appointment to the nation's highest military post as Chairman of the Joint Chiefs of Staff during the Cold War.

Anthoni van Noordt: Historical and Analytical Analysis of His Tabulatuurboeck van Psalmen en Fantasyen of 1659
This dissertation presents a historical and analytical study of the organ works of Anthoni van Noordt. Van Noordt's Tabulatuurboeck is one of the most important music publications in mid-seventeenth-century Netherlands. It gives unique, valuable information on organ playing of its time. The process of discrete analysis has led to the identification and exploration of many details, such as extensive use of pedal, the reliance of the composer on rhetorical principals of composition, and his integration of the Italian and German principals of ensemble techniques. The dissertation is divided into three major parts. The first part contains chapters on van Noordt's biography based on available archival documents as well as a chapter on the organ and its role in seventeenth -century Amsterdam. The second part is solely dedicated to the Tabulatuurboeck examining the physical and technical features of the publication including the style of the publication, the letter and staff notation, hand positions, and rhetorical components. Finally, the third part studies the music and its peculiar characteristics with separate chapters on the variations and fantasias.

Use of In-Stream Water Quality Measurements and Geospatial Parameters to Predict Consumer Surfactant Toxic Units in the Upper Trinity River Watershed, Texas
Surfactants are used in a wide assortment of "down-the-drain" consumer products, yet they are often discharged in wastewater treatment plant effluent into receiving water, potentially causing environmental harm. The objective of this project was to predict surfactant toxic units and in-stream nutrients in the upper Trinity River watershed. Surface and pore water samples were collected in late summer 2005. General chemistries and surfactant toxic units were calculated. GIS models of anthropogenic and natural factors were collected and analyzed according to subwatersheds. Multiple regression analyses using the Maximum R2 improvement method were performed to predict surfactant toxic units and in-stream nutrients using GIS and in-stream values. Both geospatial and in-stream parameters generated multiple regression models for surfactant surface and pore water toxic units, as well as in-stream nutrients, with high R2 values. Thus, GIS and in-stream parameter modeling have the potential to be reliable and inexpensive method of predicting surfactant toxic units and nutrient loading in the upper Trinity River watershed.

Teenager's doing history out-of-school: An intrinsic case study of situated learning in history.
This intrinsic case study documents a community-based history expedition implemented as a project-based, voluntary, out-of-school history activity. The expedition's development was informed by the National Education Association's concept of the intensive study of history, its structure by the history seminary, and its spirit by Webb's account of seminar as history expedition. Specific study objectives included documentation of the planning, implementation, operation, and outcomes of the expedition, as well as the viability of the history expedition as a vehicle for engaging teenagers in the practice of history. Finally, the study examined whether a history expedition might serve as a curriculum of identity. Constructivist philosophy and situated learning theory grounded the analysis and interpretation of the study. Undertaken in North Central Texas, the study followed the experiences of six teenagers engaged as historians who were given one year to research and write a historical monograph. The monograph concerned the last horse cavalry regiment deployed overseas as a mounted combat unit by the U.S. Army during World War II. The study yielded qualitative data in the form of researcher observations, participant interviews, artifacts of participant writing, and participant speeches. In addition, the study includes evaluations of the historical monograph by subject matter experts. …

Milk machines: Exploring the breastfeeding apparatus.
Arguing that current discourse surrounding breastfeeding and the lactating body promotes management of the female body, I attempt to devise an explanation of the breastfeeding apparatus and its strategies. In this study, the strategies include visual and linguistic representations of breastfeeding through art, promotional materials for advertisement and recommendations from the medical community, and the language used in the legal protection of breastfeeding. Using a rhetorical lens, I explore how these varied junctions operate within the breastfeeding apparatus and how breastfeeding is both a product of and a product in the technology. I seek to find what else is at work and how breastfeeding functions as a discursive element in its own right, allowing it to function as an apparatus for control. Finally, I question the potential for resistance in breastfeeding, asking if the lactating body has options, or is the subject so policed and managed that decisions are dictated by the breastfeeding apparatus.

Yoon-Seong Cho's Jazz Korea: A Cross-cultural Musical Excursion
This thesis examines Yoon-Seong Cho's critically acclaimed recording Jazz Korea, in which Cho unites Korean folk music and American jazz into a single form of expression. By reinterpreting Korean folk music through jazz, Cho stimulated interest in the Korean jazz scene and a renewed interest in Korean traditional folk songs. The goal of the thesis, the first musicological essay about Yoon-Seong Cho, is to understand how Cho's diasporic experiences affected his music by leading to a process of self-discovery that allowed Cho to interpret his own identity. Through musical analysis, the study proposes a cultural interpretation of two of Cho's pieces that have achieved popularity not only among Koreans but also internationally: "Arirang" and Han-O-Baek-Nyun.

Polyethylene-layered double hydroxide and montmorillonite nanocomposites: Thermal, mechanical and flame retardance properties.
The effect of incorporation two clays; layered double hydroxides (LDH) and montmorillonite layered silicates (MLS) in linear low density polyethylene (PE) matrix was investigated. MLS and LDH were added of 5, 15, 30 and 60 weight percent in the PE and compounded using a Brabender. Ground pellets were subsequently compression molded. Dispersion of the clays was analyzed using optical microscopy, SEM and XRD. Both the layered clays were immiscible with the PE matrix and agglomerates formed with increased clay concentration. The thermal properties were studied by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). Both clays served as nucleation enhancers increasing recrystallization temperatures in the composites. Flame retarding properties were determined by using the flammability HVUL-94 system. LDH indicated better flame retarding properties than MLS for PE. The char structure was analyzed by environmental scanning electron microscopy. Mechanical properties were studied by tensile testing and Vickers microhardness testing apparatus.

"Victory is Our Only Road to Peace": Texas, Wartime Morale, and Confederate Nationalism, 1860-1865
This thesis explores the impact of home front and battlefield morale on Texas's civilian and military population during the Civil War. It addresses the creation, maintenance, and eventual surrender of Confederate nationalism and identity among Texans from five different counties: Colorado, Dallas, Galveston, Harrison, and Travis. The war divided Texans into three distinct groups: civilians on the home front, soldiers serving in theaters outside of the state, and soldiers serving within Texas's borders. Different environments, experiences, and morale affected the manner in which civilians and soldiers identified with the Confederate war effort. This study relies on contemporary letters, diaries, newspaper reports, and government records to evaluate how morale influenced national dedication and loyalty to the Confederacy among various segments of Texas's population.

Dangerous, Desperate, and Homosexual: Cinematic Representations of the Male Prostitute as Fallen Angels
The purpose of this study is to frame the cinematic male prostitute as a "fallen angel" to demonstrate that the evolution of the cinematic hustler has paralleled historicized ideological definitions of male homosexuality. Because cultural understandings of male homosexuality frequently reflect Judeo-Christian ideological significations of sin and corruption, the term "fallen angel" is utilized to describe the hustler as a figure who has also succumbed to sin due to his sexual involvement with other men. This study constructs an epochal analysis of eight films that explores the confluence of the social understanding of homosexuality with the cinematic image of the hustler from the mid 1960s through the present. In doing so, this study shows that the image of the cinematic hustler is intricately tied to the image of the male homosexual in material cultures and eras that produce them. A filmography is included.

Wyatt Cephas Hedrick: Builder of Cities
Wyatt Cephas Hedrick, builder and architect, was born in Virginia in 1888 and came to Texas in 1913. At his death in 1964, Hedrick's companies had managed construction projects worth more than $1.3 billion. Hedrick's architectural business designed and built edifices of all kinds, including educational facilities, hotels, military bases, railroad terminals, courthouses, and road systems. His companies built all over the United States, and in some foreign countries, but primarily in Texas. The purpose of Hedrick's structures and their architectural styles changed to accommodate historical events. This can be seen by examining many of the commissions he received during the 1920s and 1930s. Hedrick had a unique opportunity to participate in years of great change and development in Texas, and he played a vital role in the history of those times. This thesis examines the career of Wyatt C. Hedrick from his beginnings in Virginia through his years in Texas, closing in 1940. As a builder, he played a major role in changing the skylines of Texas cities, especially Fort Worth.

The relationship of racial identity, psychological adjustment, and social capital, and their effects on academic outcomes of Taiwanese aboriginal five-year junior college students.
The study was conducted during November and December 2006, and the participants were Taiwanese aboriginal students at five-year junior colleges in Taiwan. Five hundred students from twenty junior colleges were recruited, and completed data for 226 students were analyzed. The data were collected by scoring the responses on six instruments which measured Taiwanese aboriginal junior college students' potential social capital, racial identity development, academic outcome (expected grade) and their psychological adjustment (stress, social support, self-esteem, and academic engagement). The instruments were designed to gather information on the following: (a) potential social capital scale; (b) multigroup ethnic identity measure; (c) racial identity attitude scale; (d) perceived stress scales; (e) self-esteem scale; (f) social support scale; (g) academic engagement scale; (h) academic outcome (expected grade). This quantitative design used SPSS 12 to analyze the data. Independent t-tests, Pearson correlation coefficient, regression model, ANOVA, ANCOVA were applied in the study. Results from this study indicate racial identity affects academic outcome with the covariate of psychological adjustment. This finding contradicts previous research that racial identity cannot affect students' psychological adjustment and academic achievement in higher education. For social capital, the study provides encouraging evidence that social capital is directly, significantly correlated with academic outcomes …

Parental Perception of Satisfaction and Understanding of Special Education Services
The purpose of this study was to examine the satisfaction and understanding of parents of young children with disabilities in North Texas in regard to the special education services they receive through their local education authority. A mixed non-experimental research design utilizing the survey method was used to obtain the data collected from a sample of 230 parents with children with disabilities from preschool to elementary ages. Factorial analysis techniques were first used to assess the validity of the 14 quantitative items by splitting the sample into 2 equivalent groups: the development group and the validation group. Exploratory factor analysis extracted 2 factors after eliminating 4 items: satisfaction and understanding. This 2-factor structure was confirmed in the validation group. The final 10-item survey demonstrated satisfactory reliability and validity. Overall, parents were very satisfied with the special education services and reported a good understanding of those services. Two x two (number of children x years of services) ANOVAs were used to examine the differences on parental satisfaction and understanding. No statistically significant differences were found except that parents with 2 or 3 children were more satisfied than the counterparts with only 1 child in the special education program. This difference was …

Post-Implementation Evaluation of Enterprise Resource Planning (ERP) Systems
The purposes of this dissertation were to define enterprise resource planning (ERP) systems, assess the varying performance benefits flowing from different ERP system implementation statuses, and investigate the impact of critical success factors (CSFs) on the ERP system deployment process. A conceptual model was developed and a survey instrument constructed to gather data for testing the hypothesized model relationships. Data were collected through a cross-sectional field study of Indian production firms considered pioneers in understanding and implementing ERP systems. The sample data were drawn from a target population of 900 firms belonging to the Confederation of Indian Industry (CII). The production firms in the CII member directory represent a well-balanced mix of firms of different sizes, production processes, and industries. The conceptual model was tested using factor analysis, multiple linear regression analysis and univariate Anova. The results indicate that the contributions of different ERP system modules vary with different measures of changes in performance and that a holistic ERP system contributes to performance changes. The results further indicate that the contributions of CSFs vary with different measures of changes in performance and that CSFs and the holistic ERP system influences the success achieved from deployments. Also, firms that emphasize CSFs …

Transfer of "good" and "bad" functions within stimulus equivalence classes.
This study compared results of two experiments that tested transfer of function in stimulus equivalence classes in a task dissimilar to (in Experiment I) and similar to (in Experiment II) the task that trained functional responding. Eleven students from UNT participated in return for monetary compensation. Phase 1 and 2 were identical in the two experiments, in which they established stimulus equivalence classes and functional responding, respectively. Each experiment then used different tasks in the third phase to test differential responding. Only participants in Experiment II demonstrated consistent transfer of function. Results are discussed in terms of how task similarity may function as a type of contextual control when there is limited experience with the task.

From "Living Hell" to "New Normal": Illuminating Self-Identity, Stigma Negotiation, and Mutual Support among Female Former Sex Workers
Women in the sex industry struggle with emotional turmoil, drug and alcohol addiction, poverty, and spiritual disillusionment. Their lived experiences as stigmatized individuals engender feelings of powerlessness, which inhibits their attempts to leave the sex industry. This study illuminates how personal narratives develop throughout the process of shedding stigmatized identities and how mutual support functions as a tool in life transformation. Social identity theory and feminist standpoint theory are used as theoretical frameworks of this research, with each theory adding nuanced understanding to life transformations of female former sex workers. Results indicate that women in the sex industry share common narratives that reveal experiences of a "Living Hell", transitional language, and ultimate alignment with traditional norms. Implications of SIT and FST reveal the role of feminist organizations as possible patriarchal entities and adherence to stereotypical masculine ideology as an anchoring factor in continued sex work.

Incarcerated mothers in Cuenca, Ecuador: Perceptions of their environment and the impact it has on the lives of their young children and their education.
The number of children whose mothers are incarcerated is increasing around the world. Educators of young children are faced with new challenges in their classrooms as they work with these children during their formative years for social-emotional development. The purpose of this qualitative study was to interview the mothers, in order to gain their perspective on how they feel their incarceration has affected their relationship with their children; how they believed it would affect their children in the future, and to investigate the perceptions of early childhood teachers who worked with children of incarcerated mothers. Using interviews, observations, journal, and field notes the researcher collected information from 3 incarcerated mothers, 3 of their children, and the 2 teachers who worked with these children. Overall findings were that the mother-child relationships are of extreme importance to the mothers. They have high hopes for a better life for their child, which includes concerns about their education. Mothers had fears that their incarceration would repeat itself in their children and desired for things to be different in their children's futures. They reported their incarceration affecting their children in negative ways. Their children had difficulty depicting their mothers in their drawings. Lastly, the teachers …

With their hearts in their hands: Forging a Mexican community in Dallas, 1900-1925.
Mexican immigration to the United States increased tremendously from 1900-1925 as factors such as the Mexican Revolution and the recruitment of Mexican laborers by American industry drew Mexicans north. A significant number of Mexicans settled in Dallas and in the face of Anglo discrimination and segregation in the workplace, public institutions, and housing, these immigrants forged a community in the city rooted in their Mexican identity and traditions. This research, based heavily on data from the 1900, 1910, and 1920 census enumerations for Dallas and on articles from Dallas Morning News, highlights the agency of the Mexican population - men and women - in Dallas in the first three decades of the twentieth century.

The Effectiveness of Using Lego Mindstorms Robotics Activities to Influence Self-regulated Learning in a University Introductory Computer Programming Course.
The research described in this dissertation examines the possible link between self-regulated learning and LEGO Mindstorms robotics activities in teaching concepts in an introductory university computer programming course. The areas of student motivation, learning strategies, and mastery of course objectives are investigated. In all three cases analysis failed to reveal any statistically significant differences between the traditional control group and the experimental LEGO Mindstorms group as measured by the Motivated Strategies for Learning Questionnaire and course exams. Possible reasons for the lack of positive results include technical problems and limitations of the LEGO Mindstorms systems, limited number and availability of robots outside of class, limited amount of time during the semester for the robotics activities, and a possible difference in effectiveness based on gender. Responses to student follow-up questions, however, suggest that at least some of the students really enjoyed the LEGO activities. As with any teaching tool or activity, there are numerous ways in which LEGO Mindstorms can be incorporated into learning. This study explores whether or not LEGO Mindstorms are an effective tool for teaching introductory computer programming at the university level and how these systems can best be utilized.

Nontraditional name changes for men: Attitudes of men and women.
Recently, some men have taken their wives' last names upon marriage rather than following tradition. The goal of this study was to examine the attitudes that men and women have toward these nontraditional men. Ideological hegemony and social identity theory comprised the framework for examining participants' beliefs. A survey first elicited participants' extant sexist beliefs about men and the characteristics of a nontraditional man compared to a traditional man. An open-ended question further explored participants' opinions. The results indicated that benevolent sexism influences respondents' attitudes towards nontraditional men and that most respondents view nontraditional men as more nurturing and committed to their marriage than traditional men. The results further revealed a dichotomy of positive and negative attitudes towards nontraditional men indicating that society's feelings about nontraditional men are changing.

Between Logos and Eros: New Orleans' Confrontation with Modernity
This thesis examines the environmental and social consequences of maintaining the artificial divide between thinking and feeling, mind and matter, logos and eros. New Orleans, a city where the natural environment and human sensuality are both dominant forces, is used as a case study to explore the implications of our attempts to impose rational controls on nature - both physical and human nature. An analysis of New Orleans leading up to and immediately following Hurricane Katrina (2005) reveals that the root of the trouble in the city is not primarily environmental, technological, political, or sociological, but philosophical: there is something amiss in the relationship between human rationality and the corporeal world. I argue that policy decisions which do not include the contributions of experts from the humanities and qualitative social sciences - persons with expertise on human emotions, intentions, priorities and desires - will continue to be severely compromised.

Understanding knowledge management and organizational adaptation and the influencing effects of trust and industrial cluster.
Due to rapid environmental change, today's business requires a more collaborative management to ensure positive performance. One of the important means that can help firms adapt successfully to a changing environment is knowledge management. The management of information and knowledge as key to retaining competitive advantage and has recently evolved into a more strategically focused research topic for both business and academic study. Managing knowledge, however, is deemed difficult because many companies recognize the importance of their proprietary knowledge and are not willing to share it freely. Recognizing this weakness, many countries have promoted the development of regional clusters where firms can co-develop their competences and competitive advantage against the world's best competitors by sharing knowledge, resources, and innovative capabilities. Other than industrial clusters, trust is also considered an important factor in knowledge management study. Trust reduces the need to monitor others' behaviors, formalize procedures, and it lowers transaction costs. At the macro level, trust can enhance organizations' core competencies and sustain their competitive advantages through co-evolution. This may occur through the development of group collaborations, cooperative relationships, and networks. The study adopted a field survey research method and used multiple regressions as the data analysis technique. The dependent variable …

Liquid Nitrogen Propulsion Systems for Automotive Applications: Calculation of Mechanical Efficiency of a Dual, Double-acting Piston Propulsion System
A dual, double-acting propulsion system is analyzed to determine how efficiently it can convert the potential energy available from liquid nitrogen into useful work. The two double-acting pistons (high- and low-pressure) were analyzed by using a Matlab-Simulink computer simulation to determine their respective mechanical efficiencies. The flow circuit for the entire system was analyzed by using flow circuit analysis software to determine pressure losses throughout the system at the required mass flow rates. The results of the piston simulation indicate that the two pistons analyzed are very efficient at transferring energy into useful work. The flow circuit analysis shows that the system can adequately maintain the mass flow rate requirements of the pistons but also identifies components that have a significant impact on the performance of the system. The results of the analysis indicate that the nitrogen propulsion system meets the intended goals of its designers.
