Cracking the Closed Society: James W. Silver and the Civil Rights Movement in Mississippi

This thesis examines the life of James Wesley Silver, a professor of history at the University of Mississippi for twenty-six years and author of Mississippi: The Closed Society, a scathing attack on the Magnolia State's history of racial oppression. In 1962, Silver witnessed the campus riot resulting from James Meredith's enrollment as the first black student at the state's hallowed public university and claims this was the catalyst for writing his book. However, by examining James Silver's personal and professional activities and comparing them with the political, cultural, and social events taking place concurrently, this paper demonstrates that his entire life, the gamut of his experiences, culminated in the creation of his own rebel yell, Mississippi: The Closed Society. Chapter 1 establishes Silver's environment by exploring the history and sociology of the South during the years of his residency. Chapter 2 discusses Silver's background and early years, culminating with his appointment as a faculty member of the University of Mississippi in 1936. Chapter 3 reveals Silver's personal and professional life during the 1940s, as well as the era's notable historical events. The decade of the 1950s is discussed in chapter 4, particularly the civil rights movement, Silver's response to these …

Exploring a Community Partnership: A Narrative Inquiry into the 2004-2006 Semester Programs Between Artpace San Antonio and Louis W. Fox Academic and Technical High School

This qualitative inquiry explores a community-based art partnership called the semester programs that took place between Artpace San Antonio and Louis W. Fox Academic and Technical High School from 2004 until 2006. This narrative inquiry used interviews with artists and former Fox Tech art students involved in our program, along with my teacher/ researcher reflections, to make meaning from the data. The artists involved in the semester programs were Gary Sweeney, Daniel Guerrero, David Jurist, and Ethel Shipton. Former students interviewed include Eloy McGarity, Rosa Leija, John Contreras, and Jennelle Gomez, while I, Maria Leake represent the voice of the art teacher. Our stories of experience were analyzed and connections between situated learning theory, creativity theories, community-based art education, and memory research were all recognized as being exhibited during our community partnership programs. There were seven patterns and themes that were noted as occurring within each semester program, as well as notable distinctions. The patterns and themes from the data analysis suggest that our community partnership reflected the following: learning and creative expression went beyond the individual; networks of support and communication were available to all participants; challenges were acknowledged; empathy between participants was an unintentional outcome; working together as …

An Exploratory Study of the Impact of Institutional Policies and Practices of Community and Technical Colleges in Texas on Student Persistence in Online Courses (open access)

An Exploratory Study of the Impact of Institutional Policies and Practices of Community and Technical Colleges in Texas on Student Persistence in Online Courses

Online education is the fastest growing form of course delivery of higher education in the United States. It has revolutionized how students and instructors interact in the educational process. Yet students in online courses continue to experience higher attrition rates than their counterparts in traditional face-to-face classes despite the advantages offered by the technology. This study examined the impact that institutional policies and practices at community colleges in the state of Texas have had on student persistence in online courses. It also examined how institutions collect and use data in addressing students' attrition. The findings were used to identify the most effective institutional practices to share with community college systems in Texas in an effort to improve student persistence in online courses across the state. The population for the study consisted of the 50 public two-year community college and the technical college systems in the state of Texas. The study used a mixed method. A theoretical model of institutional impact on online persistence was drawn from the literature review. This model's five categories were then used to construct a survey to collect data on institutional practices and measure the effectiveness in addressing student persistence. Four college systems were identified using …

Endocannabinoid System in a Planarian Model (open access)

Endocannabinoid System in a Planarian Model

In this study, the presence and possible function of endocannabinoid ligands in the planarian is investigated. The endocannabinoids ananadamide (AEA) and 2-arachidonoylglycerol (2-AG) and entourage NAE compounds palmitoylethanolamide (PEA), stearoylethanolamide (SEA) and oleoylethanolamide (OEA) were found in Dugesia dorotocephala. Changes in SEA, PEA, and AEA levels were observed over the initial twelve hours of active regeneration. Exogenously applied AEA, 2-AG and their catabolic inhibition effected biphasic changes in locomotor velocity, analogous to those observed in murines. The genome of a close relative, Schmidtea mediterranea, courtesy of the University of Utah S. med genome database, was explored for cannabinoid receptors, none were found. A putative fatty acid amide hydrolase (FAAH) homolog was found in Schmidtea mediterranea.

Understanding Quality of Life in Older Adults (open access)

Understanding Quality of Life in Older Adults

I analyzed the 2004 and 2006 Health and Retirement Study data to test structural equation models of the quality of life (QOL) construct. The participants (N = 1352) were non-institutionalized individuals aged 42 and older (M = 65.70, SD = 10.88), with an average education of 12.73 years (SD = 2.96) and of varied ethnicities. The results indicated that physical functioning, affective experience, life satisfaction and social support could serve as indicators for a second order QOL factor. Furthermore, the developed QOL model explained 96% of the variance of the CASP-19 (Control, Autonomy, Self-realization and Pleasure), a QOL measure that reflects fulfillment of psychological needs. The results also indicated that Depression and Life Satisfaction are related through reciprocal causation and that Physical Functioning is more likely to cause a change in Depression than the reverse. The results suggest that QOL is a complex, multidimensional concept that should be studied at different levels of analysis.

Relationships Among and Between Early and Late Freshmen Admission Applications and Academic Persistence (open access)

Relationships Among and Between Early and Late Freshmen Admission Applications and Academic Persistence

This quantitative study investigated relationships among and between university early and late admitted freshmen and academic performance and persistence. The participants in this study consisted of 3,197 early freshmen applicants and 309 late freshmen applicants admitted at a large southwestern student centered public research university over the course of the year prior to the fall 2008 academic year. Significant results, using a statistical significance level of p < .05, were reported for the majority of variables examined: chi-square analysis revealed a significant relationship between application date and ethnicity; independent-samples t-tests revealed significant differences in SAT scores; 78.06% of late applicants were male compared to 40.83% of early applicants; mean GPA of early applicants was 2.62 compared to 2.18 among those who applied late; and lastly, 76.62% of early applicants returned the following year in comparison to 57.42% of late applicants. The results of this study provide preliminary support for the examination of admission policies and procedures in relation to late application. Recommendations are made for advising, counseling, and other interventions that may ease the transition of freshmen late applicants while enhancing retention and persistence.

Living-learning communities and ethnicity: A study on closing the achievement gap at Regional University

This quasi-experimental study examined the impact of living-learning communities on GPA and fall-to-fall retention rates for college freshmen at Regional University (RU). The specific focus of this study was the effect of these communities on students of different ethnic groups and on the potential of these communities to reduce the academic performance gap. RU was a small public university that offered both undergraduate and graduate degree programs. RU required all freshman students to live on campus in living-learning communities beginning with the 2007-2008 academic year. This study utilized the 343 student freshman cohort class of 2008 in the living-learning communities as the treatment group. This treatment group was compared against the 193 student freshman cohort class of 2008 living off campus and against the 643 student freshman cohort class of 2006 living on campus prior to the implementation of living-learning communities. In addition, the statistics were analyzed by ethnicity to examine the impact of these communities on White, Hispanic, African American, and Native American students and their ability to reduce the academic performance gap. The research revealed that the communities implemented at RU were not statistically significant at improving academic performance or at reducing the achievement gap. The results of …

A Quantitative Analysis of the Relationship of a Non-traditional New Student Orientation in an Urban Community College with Student Retention and Grade Point Average Among Ethnic Groups

This quantitative study examined relationships of attending a new student orientation program related to student retention and academic success. A research group of 464 students of Tarrant County College Northwest, a community college campus in Fort Worth, Texas, who voluntarily attended a 2-hour pre-semester new student orientation program was compared to a group of 464 students on the same campus who did not attend the program. Comparisons were made with regard to retention and GPA. Ethnic ratios of both groups are 4% Black, 26% Hispanic, 66% White, and 4% other ethnicities. Chi square data analysis was utilized to determine if statistically significant differences relating to student retention existed between the groups. The independent t-test was used to compare means of calculated GPAs between groups. A one-way ANOVA was used to compare the means of GPAs for ethnic sub-groups. The total group and the Black sub-group showed statistically significant higher levels of second-semester retention (total group p = .018; Black sub-group p = .008) and higher calculated GPAs (total group p = .016; Black sub-group p = .019). No statistically significant results were found among Hispanic students.

Programming for Students with Emotional/Behavioral Disorders: The Importance, Usage and Preparedness for Implementation of Evidence-Based Interventions Based on Practitioner Perceptions

Implementation of evidence-based practices in Texas schools was examined through a survey disseminated through 495 special education directors in 20 state educational service centers. The district-level directors were asked to forward the survey to all personnel providing direct or indirect services to students with EBD. Survey participants were asked to rate 27 evidence-based interventions for students with EBD in three categories on a 5-point Likert scale: (a) importance of the intervention; (b) frequency of use of the intervention; and (c) preparedness to implement the intervention. With a response rate of 32% and representation from all 20 educational service center areas, data were analyzed through simple frequency statistics to determine that most respondents were public school special educators who had been in their current position for 5 years or less. They identified a climate that supports successful teaching and learning and clear rules/expectations as very important. They reported using procedures for the use of physical restraint most frequently, and being most well-prepared to implement clear rules/expectations. A canonical correlation analysis revealed an inverse relationship between importance ratings of tertiary level interventions and frequency of use and preparedness to implement primary level interventions which implies that while practitioners rate tertiary level interventions …

Comparing Indices of Happiness during Teaching Interactions (open access)

Comparing Indices of Happiness during Teaching Interactions

The measurement of happiness has received increasing attention in behavior analytic literature. Happiness in individuals with developmental disabilities has been assessed by 1) counting a specific behavior, or 2) sampling constellations of behaviors. The purpose of this study was to examine the two approaches while observing nine child and teacher dyads at an autism treatment center. Results showed that, overall, a constellation of behaviors can yield similar patterns when compared to a specific behavior count. However, the affect of one person did not predict the affect of the other and similar instructional conditions did not predict affect either. The implications of these results and future directions are discussed.

Culture and Self-Representation in the Este Court: Ercole Strozzi's Funeral Elegy of Eleonora of Aragon, a Text, Translation, and Commentary. (open access)

Culture and Self-Representation in the Este Court: Ercole Strozzi's Funeral Elegy of Eleonora of Aragon, a Text, Translation, and Commentary.

This dissertation presents a previously unedited text by one of the most distinguished- yet neglected-Latin writers of the Italian Renaissance, Ercole Strozzi (1471-1508), a poet and administrator in the court of Ferrara. Under the Este Dukes, Ferrara became a major center of literary and artistic patronage. The Latin literary output of the court, however, has received insufficient scholarly scrutiny. The text is a verse funeral elegy of Eleonora of Aragon (1450-1493), the first Duchess of Ferrara. Eleonora was a remarkable woman whose talents and indefatigable efforts on behalf of her husband, her children, and her state, won her accolades both at home and abroad. She also served as a prototype for the remarkable careers of her two daughters, Isabella d'Este, and Beatrice d'Este, who are celebrated for their erudition and patronage of arts and letters. The text is a mirror of the Estense court and reveals to us how its members no doubt saw themselves, at the very peak of its temporal power and the height of its prestige as a center of cultural creativity. It is also important for the striking portrait it presents of Eleonora. Ercole Strozzi chose to call his poem an epicedium, an ancient minor literary …

The Effects of Copying Before, Copying After, and Guessing on Acquisition Rate and Retention (open access)

The Effects of Copying Before, Copying After, and Guessing on Acquisition Rate and Retention

Computer-based instructional programs are being used more frequently in classrooms. While these programs offer many benefits from traditional teaching methods, humans still need to program them. There is inconsistency in the literature regarding the best way to design such programs. The purpose of this study was to evaluate the effects of three training procedures in teaching individuals to type a specified three-letter response in the presence of a corresponding symbol. Results show that the training format that prompted individuals to copy the correct response before the opportunity to respond was more efficient than viewing the correct response after an error, or copying the correct response after an error. A discussion of the results as well as implications for classroom use is also provided.

From Outward Appearance to Inner Reality: A Reading of Aaron Copland's Inscape

About 8.3% of individuals diagnosed with diabetes mellitus (DM) are diagnosed with comorbid depression, a higher rate than the general adult population. This project examined the differences of depression symptoms experienced between diabetic and matched non-diabetic individuals and the relationship of daily activity and nutrition behaviors with depression between these groups. The 2005-2006 National Health and Nutrition Examination Survey (NHANES) was utilized to assess: depression symptoms, diabetic glycemic control as measured by glycoginated hemoglobin (HbA1c), amount of physical activity, percentage of macronutrients, daily frequencies of foods consumed, and the use of nutritional food labels to make food choices. A sample of diabetic (n = 451) and non-diabetic individuals (n = 451) were matched to on age, gender, ethnicity, and education. The diabetic individuals experienced greater depression on both continuous and ordinal diagnostic variables. Counter to expectation, there was no relationship observed between depression and HbA1c in diabetic individuals, r = .04, p > .05.

Incorporating Flow for a Comic [Book] Corrective of Rhetcon

In this essay, I examined the significance of graphic novels as polyvalent texts that hold the potential for creating an aesthetic sense of flow for readers and consumers. In building a justification for the rhetorical examination of comic book culture, I looked at Kenneth Burke's critique of art under capitalism in order to explore the dimensions between comic book creation, distribution, consumption, and reaction from fandom. I also examined Victor Turner's theoretical scope of flow, as an aesthetic related to ritual, communitas, and the liminoid. I analyzed the graphic novels Green Lantern: Rebirth and Y: The Last Man as case studies toward the rhetorical significance of retroactive continuity and the somatic potential of comic books to serve as equipment for living. These conclusions lay groundwork for multiple directions of future research.

161 Glass: Site Specific Music in an Artistic Context

The composition 161 Glass is a 17-minute musical work with percussion, wind and brass instruments in which the intersection of mid-century architecture, and the art and culture of a dynamic city are inextricably linked. Through this paper, I explore the process of composing a musical work in relationship to the significance of site specific context. The paper begins by defining the concept of site specific art works; then reviews the discourse of the intersection of art, music and architecture. I then delve into the cultural and geographic context surrounding this project from the modern era through the present, and how those perspectives apply to the building and my piece. I reveal how the composition relates the musical ideas to the site. Finally, I describe the collaborative process between myself, the musicians and the Dallas Contemporary staff.

Determination of saccharides and ethanol from biomass conversion using Raman spectroscopy: Effects of pretreatment and enzyme composition

This dissertation focuses on the development of facile and rapid quantitative Raman spectroscopy measurements for the determination of conversion products in producing bioethanol from corn stover. Raman spectroscopy was chosen to determine glucose, xylose and ethanol in complex hydrolysis and fermentation matrices. Chapter 1 describes the motives and main goals of this work, and includes an introduction to biomass, commonly used pretreatment methods, hydrolysis and fermentation reactions. The principles of Raman spectroscopy, its advantages and applications related to biomass analysis are also illustrated. Chapter 2 and 3 comprise two published or submitted manuscripts, and the thesis concludes with an appendix. In Chapter 2, a Raman spectroscopic protocol is described to study the efficiency of enzymatic hydrolysis of cellulose by measuring the main product in hydrolysate, glucose. Two commonly utilized pretreatment methods were investigated in order to understand their effect on glucose measurements by Raman spectroscopy. Second, a similar method was set up to determine the concentration of ethanol in fermentation broth. Both of these measurements are challenged by the presence of complex matrices. In Chapter 3, a quantitative comparison of pretreatment protocols and the effect of enzyme composition are studied using systematic methods. A multipeak fitting algorithm was developed to …

Identification of highly gifted 5- and 6-year-old children: Measures to predict academic achievement.

Studies indicate the educational needs of highly gifted students are best met through accelerated learning. It is difficult to recognize very young children that are suited for an accelerated curriculum because younger students frequently lack school records or portfolios used to identify gifted students. This study examined the accuracy of cognitive ability and achievement tests in predicting academic achievement by the end of second grade, correlating test results and final grade averages collected from sixteen children ages five to six who entered a public school program for high-ability learners in kindergarten. A multiple regression analysis indicated the Wechsler Preschool and Primary Scale of Intelligence produced the highest mean IQ score and a strong correlation with reading achievement. The Wechsler Individual Achievement Test contributed in small part to the prediction of academic achievement. The Naglieri Nonverbal Ability Test and the Kaufman Brief Intelligence Test-Second Edition had negative correlations with final grade averages, indicating they are not predictors of academic achievement for these students.

Adult Attachment Patterns, Mental Representation of Self, and Faith: Mediators of Childhood Trauma and Affect-Behavior Regulations in Adulthood

The purpose of this study was to investigate psychological mechanism by which four intra- and inter-personal characteristics of an individual (anxious and avoidant adult attachment patterns, images of self, and religious faith) mediate the relationship between childhood trauma and each of three affect-behavior regulation problems in adulthood (symptoms of depression, disordered eating behaviors, and substance abuse). A total of 401 college student participants completed a packet of 18 surveys including 10 surveys used in the present study. Structural equation modeling was used to test each of three hypothesized structural models (Depression, Eating Disturbances, and Substance Abuse). A series of multi-group analyses conducted to test if each of three hypothesized models is invariant across gender indicated no significant difference between females and males. Thus, the data were combined across gender to test for mediated effects in each of three hypothesized models. The results indicated: (a) for the hypothesized model for depression, anxious attachment patterns, avoidant attachment patterns, and negative self-images, but not religious faith, fully mediated the relationship between childhood trauma and symptoms of depression; (b) for the model for eating disturbances, anxious attachment and negative images of self, but not avoidant attachment and religious faith, fully mediated the association between …

Information Seeking Behavior of Crime Scene Investigators in the Turkish National Police (open access)

Information Seeking Behavior of Crime Scene Investigators in the Turkish National Police

This exploratory research is the first one among occupational information seeking behavior studies that focuses on information seeking behaviors of the crime scene investigators. The data used in this dissertation were gathered via a self-administrated survey instrument from 29 cities in Turkey. Findings obtained from the data analyses show that there is a strongly positive relationship between the experience of the crime scene investigators and the use of personal knowledge and experience as a primary information source (experience is operationalized with age, service years in policing, and service years in crime scene investigation units). The findings also suggest that increasing of the level of education is negatively related to relying on immediate colleagues as an information source among the crime scene investigators. These findings are consistent with related literature and theory. The data analysis shows that crime scene investigators work in cities with higher population rates have more complaint scores than those who work in cities with lower population rates across Turkey. The findings from the data analysis may suggest valuable implications to defeat the barriers between crime scene investigators and information sources.

Explaining Marijuana Use Among Turkish Juveniles: A Test of Hirschi's Social Bonding Theory

Marijuana is the most prevalent illicit drug used in the world and among Turkish juveniles. Although studies have examined marijuana use among Turkish juveniles, none has tested Hirschi's social bonding theory, one of the most frequently tested and applied criminological theories in the United States and other Western and developed countries. This study investigated the empirical validity and generalizability of Hirschi's theory to juveniles' marijuana use in Turkey, a non-Western and developing country. Data on 2,740 Turkish tenth grade students from the 2006 Youth in Europe survey were used. Results from binary logistic regression analyses were generally consistent with the propositions of Hirschi's theory and the findings of previous empirical studies. Regarding the attachment component of the theory, Turkish juveniles who lived in two-parent families and those who were closely monitored by their parents were less likely to have tried marijuana. In addition, teens who were strongly attached to their school and religion were also less likely to have used the drug. As for the commitment component, language grade was negatively associated with marijuana use. None of the involvement items had significant effects on marijuana use in the predicted direction. Participation in club sports had a positive effect on marijuana …

Measurement of Single Spin Asymmetries in Semi-Inclusive Deep Inelastic Scattering Reaction n↑ ( e,e' pi{sup +}) X at Jefferson Lab

What constitutes the spin of the nucleon? The answer to this question is still not completely understood. Although we know the longitudinal quark spin content very well, the data on the transverse quark spin content of the nucleon is still very sparse. Semi-inclusive Deep Inelastic Scattering (SIDIS) using transversely polarized targets provide crucial information on this aspect. The data that is currently available was taken with proton and deuteron targets. The E06-010 experiment was performed at Jefferson Lab in Hall-A to measure the single spin asymmetries in the SIDIS reaction n↑(e, e′π{sup ±}/K{sup ±})X using transversely polarized {sup 3}He target. The experiment used the continuous electron beam provided by the CEBAF accelerator with a beam energy of 5.9 GeV. Hadrons were detected in a high-resolution spectrometer in coincidence with the scattered electrons detected by the BigBite spectrometer. The kinematic coverage focuses on the valence quark region, x = 0.19 to 0.34, at Q{sup 2} = 1.77 to 2.73 (GeV/c){sup 2}. This is the first measurement on a neutron target. The data from this experiment, when combined with the world data on the proton and the deuteron, will provide constraints on the transversity and Sivers distribution functions on both the u …
