Themes of Exodus and Revolution in Ellison's Invisible Man, Morrison's Beloved, and Doctorow's Ragtime (open access)

Themes of Exodus and Revolution in Ellison's Invisible Man, Morrison's Beloved, and Doctorow's Ragtime

In my dissertation I examine the steps in and performance of revolution through the writings of three Postmodern authors, Ralph Ellison, Toni Morrison, and E. L. Doctorow, in light of the model of the biblical Exodus journey and the revolution which precipitated that movement. I suggest that the revolution which began with the Israelites' bondage in Egypt has provided the foundation for American literature. I show that Invisible Man, Beloved, and Ragtime not only employ the motif of the Exodus journey; they also perpetuate the silent revolution begun by the Israelites while held captive in Egypt. This dissertation consists of six chapters. Chapter One provides the introduction to the project. Chapter Two provides the model for this study by defining the characteristics of the Exodus journey, Moses as the leader of the Israelites, and the pattern of revolution established by Michael Walzer in Exodus and Revolution. In Chapters Three, Four, and Five, I apply the model established in Chapter Two to the individual texts. In Chapter Six, I draw three conclusions which arise from my study. My first conclusion is that the master story of the Exodus journey and the Israelites' liberation from Egypt informs all Western literaturewhether the literature …

Public School Educators' Use of Computer-Mediated Communication (open access)

Public School Educators' Use of Computer-Mediated Communication

This study examined the uses of computer-mediated communication (CMC) by educators in selected public schools. It used Rogers' Diffusion of Innovation Theory as the underpinnings of the study. CMC refers to any exchange of information that involves the use of computers for communication between individuals or individuals and a machine. This study was an exploration of difficulties users confront, what services they access, and the tasks they accomplish when using CMC. It investigated the factors that affect the use of CMC. The sample population was drawn from registered users on TENET, the Texas Education Network as of December 1997. The educators were described with frequency and percentages analyzing the demographic data. For the research, eight indices were selected to test how strongly these user and environmental attributes were associated with the use of CMC. These variables were (1) education, (2) position, (3) place of employment, (4) geographic location, (5) district size, (6) organization vitality, (7) adopter resources, and (8) instrumentality Two dependent variables were used to test for usage: (1) depth or frequency of CMC usage and amount of time spent online and (2) breadth or variety of Internet utilities used. Additionally, the users' perception of network benefits was measured. …

Effects of a Surface Engineered Metallic Coating on Elastomeric Valve Stem Seal Leakage (open access)

Effects of a Surface Engineered Metallic Coating on Elastomeric Valve Stem Seal Leakage

Valve stem seal leakage is a major source of fugitive emissions, and controlling these emissions can result in added expense in leak detection and repair programs. Elastomeric O-rings can be used as valve stem seals, and O-ring manufacturers recommend lubrication of elastomeric seals to prevent damage and to assure proper sealing. In this research, a metallic coating was applied as a lubricant using a vacuum vapor deposition process to the surface of elastomeric valve stem seals. Valve stem leak measurements were taken to determine if the coated O-rings, alone or with the recommended lubrication, reduced valve stem seal leakage. This research determined that the metallic coating did not reduce valve stem leakage.

Effects of Self-Monitoring and Monetary Reward on Fluid Adherence among Adult Hemodialysis Patients (open access)

Effects of Self-Monitoring and Monetary Reward on Fluid Adherence among Adult Hemodialysis Patients

The effects of a monetary reward and self-monitoring on reducing interdialytic weight gain (IWG) were compared for 6 hemodialysis patients in an outpatient setting. A single-subject experimental design (A-B-BC-B-BC) was used to examine each variable individually and in combination, with alternating phases to control for possible sequencing effects. Monetary reward (50 cents - $3) was administered in a titrated manner according to standardized criteria, ranging from 3 % and 4% of patients' dry weight on weekdays and weekends, respectively, to 3.5% and 4.5% for weekdays and weekends. Self-monitoring involved recording daily fluid and diet intake. Results indicated that by the end of the treatment program, the 6 participants averaged a 14% reduction in weekday IWG and a 15.45% reduction in weekend IWG; however, due to significant variability, it cannot be concluded that the reductions are treatment effects. Four out of 6 participants reduced their average IWG for both weekends and weekdays by .75 kg (1.65 lb.). The average weekend reduction for these 4 participants was .85 kg (1.87 lbs.) while the average weekday reduction was .65 kg (1.43 lb.). All 6 participants showed reductions in weekday IWG that averaged .53 kg (1.17 lb.). However, only 2 participants demonstrated IWG reductions …

Head Trauma Release of Histamine from Dural Mast Cells Alters Blood-Brain Barrier: Attenuation with Zolantidine (open access)

Head Trauma Release of Histamine from Dural Mast Cells Alters Blood-Brain Barrier: Attenuation with Zolantidine

This study employed a new model of mild-to-moderate head trauma to specifically identify the role of dural mast cell (MC) histamine in trauma-induced increased permeability in the blood-brain barrier (BBB). A single line was scored partially through the left dorsal parietal skull. Immediately following the trauma, degranulation was seen in 39% of the MCs on the left and in 2% on the right. After a 20 min survival period, left duras showed 55% with MC degranulation (fewer with complete degranulation) compared to 34% on the right. In the other experiments two parallel lines were scored following the injection of Evan's blue. Histamine assay showed histamine increased in the left cortex to 154% at 5 min, 174% at 10 min, and 151% at 20 min. Fluorescent quantitation of extravasated Evan's blue at 20 min following the trauma gave an increase of 1385% over the value measured for the right cortex. Zolantidine, a selective histamine H2 receptor antagonist, administered at 10- and 20- mg/kg 30 min before the trauma blocked 65% of the Evan's blue extravasation compared with the control and 2.5 mg group.

Intentions and Implementation of the Professional Development and Appraisal System in Texas (open access)

Intentions and Implementation of the Professional Development and Appraisal System in Texas

The purpose of this study was to describe the intentions of the designers of the Professional Development and Appraisal System (PDAS) in Texas and the perceptions of teachers regarding its implementation. Information for the study was gathered in two phases using two methodologies. The first was a semi-structured interview with four expert informants instrumental in the design and implementation of the PDAS at the state level. The second component of the study was conducted with teachers using a 37-item Likert survey. The population for this phase of the study was 150 elementary and 150 secondary teachers chosen randomly from three school districts in North Central Texas. The districts were selected to represent a variety of sizes in regard to student population and represent diverse student population characteristics and socioeconomic levels. Data from the semi-structured interviews and the returned surveys were analyzed to determine the designers' intentions and areas of emphasis and to describe the alignment the teachers' perceptions and the designers' intentions. Quantitative data gathered from the surveys were analyzed using descriptive statistics as well as a correlation and function analysis and analysis based on a Cronbach alpha coefficient.

The Effects of a Therapeutic Play Intervention on Hispanic Students' Reading Achievement, Self-Concept, and Behavior (open access)

The Effects of a Therapeutic Play Intervention on Hispanic Students' Reading Achievement, Self-Concept, and Behavior

This study employed a pretest/posttest control group design to investigate the achievement of second grade Hispanic students from a predominantly low socio-economic school in a large metropolitan city. The thirty Hispanic students with the lowest scores on the Gates MacGinitie Reading Test were randomly assigned to the experimental group (n =15) or the control group (n=15). The treatment consisted of 16, 30-minute sessions of play intervention--2 times per week for 8 weeks. The providers of play therapy were school personnel trained in the principles of child-centered play therapy including tracking, reflecting feelings, and setting limits. Instruments were administered to all subjects prior to the 8 week treatment period and in the two-week period following treatment and included the GMRT, the Joseph Pre-School Primary Self-Concept Test (JPPSCST) and the Child Behavior Checklist Teacher Report Form (CBCTRF). Statistical analyses included a (t-test; 2 tail; p > .05), discriminant analysis, and cross validation. The results indicated that children who received play therapy did not achieve notably higher mean scores in reading. However, play therapy did improve the experimental group's self-concept scores and their internal behavior scores, though not significantly. All differences between the experimental and the control groups were within 1 point except …

Attitudes and Behaviors Toward Weight, Body Shape and Eating in Male and Female College Students

The purpose of this investigation was to assess the association between body mass index as well as race/ethnicity and established correlates of disordered eating including drive for thinness, body dissatisfaction, bulimia, dietary restraint and social physique anxiety in male and female college students. Difference between actual, desirable and perceived body weight was also assessed. ANOVA suggested that as actual body mass index increased, in general, attitudes and behavior toward weight, body shape and eating increased. A two-tailed t-test suggested that males and females differed significantly with regards to attitudes and behavior toward weight body shape and eating. ANOVA indicated that little to no association existed between race/ethnicity and established correlates of disordered eating.

Teachers' and Students' Perceptions of the Impact of Content Literacy Strategy Instruction on Teaching and Learning (open access)

Teachers' and Students' Perceptions of the Impact of Content Literacy Strategy Instruction on Teaching and Learning

Reading researchers agree that content literacy strategies are beneficial in helping students learn. However, teachers remain resistant to teaching the strategies. Additionally, many students, even at the college level, lack the learning strategies necessary to experience academic success. This study sought to gain a deeper understanding of the complexities of content literacy strategy instruction. The research questions that guided the study addressed the benefits, obstacles, and support and experiences needed to sustain the use of the strategies over time. Multiple data sources were used to investigate teachers' and students' perceptions of the research questions. The main benefit found was increased student understanding and learning of content; additional benefits included increased instructional repertoire, increased student engagement in class, and improved learner independence. Most of the obstacles documented in the literature were supported in the study; however, the obstacle of time was noted most frequently. Teacher confidence was observed by the researcher as an obstacle. The majority of participants indicated they would continue using the strategies learned during the study in the future. Students noted the support needed to sustain content literacy strategy use depended on teachers providing direct instruction, practice using the strategies, and personal success with the strategies. Teachers also …

Singing for Blaine and for Logan! Republican Songs as Campaign Literature in the 1884 Presidential Race (open access)

Singing for Blaine and for Logan! Republican Songs as Campaign Literature in the 1884 Presidential Race

During the presidential contest of 1884, Republicans used singing as a campaign tactic at rallies, meetings, and parades. Their songs may be divided into several categories, such as rally songs, songs of praise for the party and its candidate, "bloody shirt" songs, mudslinging songs, and issue-based songs. Songs provide a perspective on the overall tenor of the campaign, while a lack of songs on certain topics, such as temperance, reflects the party's reluctance to alienate voters by taking a strong stand on controversial issues. Although the campaign has often been called one of the dirtiest in American history, this negativity is not reflected in the majority of the songs.

The medicalization of oral aesthetics: an application of structuration theory (open access)

The medicalization of oral aesthetics: an application of structuration theory

Medicalization has been discussed at length in the sociology of health and illness literature. Typically, dialogue has centered on the effects of medicalization and the process as a phenomenon in professional fields alone. This work is an attempt to study medicalization using a theoretical model, structuration, that allows for inclusion of the larger social system in understanding health system changes and to include consumers of health services in the process as active agents. The example of oral aesthetics provides an opportunity to identify the agents of change, the process of medicalization in the larger social context, and possible indicators of the phenomenon. An attempt to operationalize the complex concept of medicalization marks a move toward creating testable theoretical models for the variety of behaviors and conditions under study as medicalized. Using content analysis of professional dental journals and lay magazines and a review of system rules and resources, shifts in language use and the emergence of medical frameworks were documented to determine if a medicalization of oral aesthetics had occurred. Results show two distinct periods within the last century when oral aesthetics have been medicalized in the United States. Evidence of turn-taking behavior among the agents is noted as well …

Happiness Is a By-Product of Function: William Burroughs and the American Pragmatist Tradition (open access)

Happiness Is a By-Product of Function: William Burroughs and the American Pragmatist Tradition

This dissertation examines the techniques and themes of William Burroughs by placing him in the American Pragmatist tradition. Chapter One presents a pragmatic critical approach to literature based on Richard Rorty and John Dewey, focusing on the primacy of narration over argumentation, redescription and dialectic, the importance of texts as experiences, the end-products of textual experiences, and the role of critic as guide to experience rather than judge. Chapter Two uses this pragmatic critical lens to focus on the writing techniques of William Burroughs as a part of the American Pragmatist tradition, with most of the focus on his controversial cut-up technique. Burroughs is a writer who upsets many of the traditional expectations of the literary writing community, just as Rorty challenges the conventions of the philosophical discourse community. Chapter Three places Burroughs within a liberal democratic tradition with respect to Rorty and John Stuart Mill. Burroughs is a champion of individual liberty; this chapter shows how Burroughs' works are meant to edify readers about the social, political, biological, and technological systems which work to control individuals and limit their liberties and understandings. The chapter also shows how Burroughs' works help liberate readers from all control systems, and examines the …

The Nativity Panel of Isenheim Altarpiece and its Relationship to the Sermo Angelicus of St. Birgitta of Sweden (open access)

The Nativity Panel of Isenheim Altarpiece and its Relationship to the Sermo Angelicus of St. Birgitta of Sweden

This thesis explores the relationship of the Sermo Angelicus of St. Birgitta of Sweden, written in the fourteenth century, with the Nativity/Concert of Angels panel of the Isenheim Altarpiece, painted by Matthias Grunewald in 1514 for a hospital and monastery run by the Antonite Order. Taking into consideration the context of the altarpiece, this thesis analyzes its iconography in relation to specific passages from the Sermo Angelicus, suggesting that the text was a possible source used by the Antonites in the Nativity/Concert of Angels panel. By doing so, parallel themes of salvation in both the text and the panel are discovered that in turn relate to the altarpiece in its entirety and present a message fashioned specifically for those patients at the hospital at Isenheim that viewed the altarpiece.

Performance Measurement, Feedback, and Reward Processes in Research and Development Work Teams: Effects on Perceptions of Performance (open access)

Performance Measurement, Feedback, and Reward Processes in Research and Development Work Teams: Effects on Perceptions of Performance

Organizations have had difficulty managing the performance of their knowledge work teams. Many of these troubles have been linked to antiquated or inadequate performance management systems along with a scarcity of empirical research on this important human resource initiative. These problems are magnified when managing the performance of research and development teams because greater ambiguity and uncertainty exists in these environments, while projects are unique and continually evolving. In addition, performance management in R&D has only recently been accepted as important while individuals in these settings are often resistant to teams. This study represented the first step in the process of understanding relationships between performance management practices and perceptions of performance in R&D work teams. Participants were 132 R&D team leaders representing 20 organizations that agreed to complete a survey via the Internet. The survey instrument was designed to examine the relationships between performance measurement, feedback, and reward processes utilized by teams in relation to measures of customer satisfaction, psychological and team effectiveness, and resource utilization and development. The most important level of performance measurement occurred at the business unit level followed next by the individual level while team level measurement was unrelated to team performance.

Relevance Thresholds: A Conjunctive/Disjunctive Model of End-User Cognition as an Evaluative Process (open access)

Relevance Thresholds: A Conjunctive/Disjunctive Model of End-User Cognition as an Evaluative Process

This investigation identifies end-user cognitive heuristics that facilitate judgment and evaluation during information retrieval (IR) system interactions. The study extends previous research surrounding relevance as a key construct for representing the value end-users ascribe to items retrieved from IR systems and the perceived effectiveness of such systems. The Lens Model of user cognition serves as the foundation for design and interpretation of the study; earlier research in problem solving, decision making, and attitude formation also contribute to the model and analysis. A self reporting instrument collected evaluative responses from 32 end-users related to 1432 retrieved items in relation to five characteristics of each item: topical, pertinence, utility, systematic, and motivational levels of relevance. The nominal nature of the data collected led to non-parametric statistical analyses that indicated that end-user evaluation of retrieved items to resolve an information problem at hand is most likely a multi-stage process. That process appears to be a cognitive progression from topic to meaning (pertinence) to functionality (use). Each step in end-user evaluative processing engages a cognitive hierarchy of heuristics that includes consideration (of appropriate cues), differentiation (the positive or negative aspects of those cues considered), and aggregation (the combination of differentiated cue aspects needed to …

"This Beautiful Evil": The Connection between Women, the Natural World, Female Sexuality, and Evil in Western Tradition (open access)

"This Beautiful Evil": The Connection between Women, the Natural World, Female Sexuality, and Evil in Western Tradition

Female archetypes reflect a social construction of reality, expressing expected modes of behavior, beliefs, and assumptions about women and are reinforced by repetition of common patterns and themes. Often female archetypes take on the physical characteristics of animals, commune with nature, engage in sexual promiscuity, and possess special powers to bewitch and control men into doing their bidding. Four prevalent archetypes include: the Predatory Woman, who with her bestial nature becomes the hunter of men; the Sacrificial Woman, who dutifully negates herself for the sake of men; the Bad Mother, who is cold, unnatural, and challenges men; and les enfants terrible seductive girl-women who at once tempt and torment men. This research traces the development and evolution of female archetypes and explores how images of women, nature, sexuality, and evil are structured within a cultural framework of Western tradition: myths and folktales, religious, philosophical, and scientific works, and film.

The Effect of Leadership Training on Manufacturing Productivity of Informal Leaders (open access)

The Effect of Leadership Training on Manufacturing Productivity of Informal Leaders

The purpose of this study was to determine if leadership training, given to informal leaders, had a positive effect on manufacturing productivity. The leadership attributes of informal leaders were assessed using the Leader Attributes Inventory (LAI). Furthermore, the performance of informal leaders was measured using the Leader Effectiveness Index (LEI). Non-management employees from various departments in a manufacturing facility were placed in one of four experimental groups. A Solomon four-group experimental design was employed. A one-group pretest-posttest design was used to control threats to internal validity. The one-way analysis of variance procedure (ANOVA) was used to determine if there were statistically significant increases in manufacturing productivity of informal leaders. Findings suggested that training increased the manufacturing productivity of informal leaders. The increased productivity indicated that leadership training could help manufacturing facilities increase their productivity without capital expenditures. Findings did not indicate a statistically significant difference in leadership attributes. Findings also suggested there were no significant differences in the manufacturing productivity between employees with high leader attributes and low leader attributes. Based on this study, leadership training, given to non-management employees, may yield gains in manufacturing productivity.

A Confirmatory Factor Analysis of WRAML Scores in a Group of Academically Talented Students

The purpose of this study was to confirm the original factor structure of the Wide Range Assessment of Memory and Learning (WRAML) utilizing a non-clinical adolescent population. Additional analysis examined the relationship between SAT-M scores and spatial relations ability. Exploratory analyses were conducted to determine ethnic and gender differences on the WRAML and subtests from the DAT. Sixty-four academically talented adolescents completed the WRAML and the mechanical reasoning and spatial relations subtests from the Differential Aptitude Test (DAT). The confirmatory factor analysis found the data obtained to not be a good fit for the factor structure of the WRAML (Sheslow & Adams, 1990). Additional confirmatory analyses were conducted which examined data fit of a three factor model found by reanalyzing the standardization data (Burton et al., 1996; Wasserman & Cambias, 1991) as well as two null models. The data failed to fit any of these three models. No support was found for the second hypothesis that predicted a positive relationship between SAT-M scores and spatial relations ability. Ethnic and gender differences on the WRAML and two DAT subtests were examined and discussed. Limitations of this study were reviewed which may have accounted for the overall lack of results.

Access: Use of this item is restricted to the UNT Community
Conservative males traditionally dominated Texas politics. In 1930, however, Sarah T. Hughes, a liberal woman from Maryland, began a spectacular career in state politics despite obstacles because of her gender and progressive ideas. First elected to the Texas Legislature in 1930, she remained active in politics for the next fifty years. Hard work, intelligence, and ability allowed her to form solid friendships with Texas's most powerful politicians. She became the first woman in Texas to hold a district judgeship, the first woman from Texas appointed to the federal bench, and the only woman to swear in a U.S. president. Hughes profoundly influenced state politics, challenging the long-standing conservative male domination. She helped to create a more diverse political field that today encompasses different ideologies and both genders.

The objective of this study was to examine the effectiveness of alternative advertising presentation formats, and the quantity of information presented in advertisements in overcoming possible information-processing deficits in senior adults that could affect their recall of ad attributes and brand name, the cognitive responses generated, and attitude toward the ad. In addition, the study examined the effectiveness of retirement status as a classification or segmentation variable in comparison with the use of the more traditional classification variable, chronological age. A convenience sample of senior adult volunteers from church groups, social clubs, and civic organizations from the local area were randomly assigned to one of nine experimental conditions. The experiment utilized a simulated magazine to test the effects of presentation formats (3 levels), and quantity of information (3 levels) on senior adult's recall, cognitive responses and attitude toward the test ads. Covariates (gender, wealth, education, activity level, health, and income) were used to reduce variance. The findings clearly indicate that the presentation format of the can ad adversely affected the memory of some senior adults. In addition, the results were significantly different across the different age levels. Retirement status was less beneficial than chronological age in the current study, but …

The Developmental Stages of Concern of Teachers Toward the Implementation of the Information Technology Curriculum in Kuwait

Change is best carried out by individual teachers, and, thus, identifying and resolving teachers’ concerns about an innovation is imperative in guiding the change process to a successful point of implementation. The purpose of this study was to identify concerns that teachers experienced when implementing the Information Technology curriculum in all intermediate schools in Kuwait and to examine the relationships among teachers’ reported stages of concern and other factors, such as gender and experience. The stages of concern, one dimension of the Concerns-Based Adoption Model (CBAM), was applied to reveal teachers’ concerns. The Stages of Concern Questionnaire (SoCQ) and a demographic survey were completed by 248 respondents. The SoCQ measures seven stages of concern that reflect three dimensions: self (awareness, informational, and personal); task (management); and impact (consequence, collaboration, and refocusing Group profile analysis revealed that teachers had four high concerns related to collaboration, personal, refocusing, and informational stages. Teachers also reported low concerns at the management and awareness stages. Both females and males reported collaboration as their greater concern. Teachers with more years of experience reported higher impact concerns. The analysis of individuals’ peak concerns revealed that the majority of the respondents were adopters of the innovation.
