Let Her Be Shorn: 1 Corinthians 11 and Female Head Shaving in Antiquity

Let Her Be Shorn: 1 Corinthians 11 and Female Head Shaving in Antiquity

Date: December 2015
Creator: Montier, Curtis E.
Description: In 1 Corinthians 11:3-15, Paul writes that if a woman is to be so immodest as to wear her hair uncovered while praying or prophesying in a Christian assembly she might as well shave her head. Paul instructs the Corinthians that it is “one and the same” for a woman to have her head shaved and for her to unveil her hair. There is a large body of works cataloging the modesty standards in Hellenistic Greece but Paul’s reference to head-shaving remains obscure. This thesis looks to find the best explanation of Paul’s instructions. Research in this topic began as an investigation of a popular modern view. It can be found in conversation or a simple Google search, that women in Ancient Greece with their head shaved were prostitutes. Beyond being prostitutes, they were probably temple prostitutes. The evidence does not bear this out as there is no artwork depicting prostitutes, or indeed any women, with their heads shaved. Instead prostitutes are shown in Greek erotic art with both long and short hair, some with and some without head coverings. Literary sources do offer several different examples of women who had their hair cut off. There are examples of women ...

Messiaen’s Musical Language: Technique and Theological Symbolism in Les Corps Glorieux, “Combat De La Mort Et De La Vie”

Messiaen’s Musical Language: Technique and Theological Symbolism in Les Corps Glorieux, “Combat De La Mort Et De La Vie”

Date: December 2015
Creator: Dellosa, Lerie Grace
Description: One of the most important ways to understand Olivier Messiaen’s musical language is through the lens of the theological ideas that many of his works convey. He considers expressing his Christian faith to be the primary purpose in his music. Through his idiosyncratic technique, Messiaen gives power and life to his religious music that he combines with his interest in literature, musical analysis, poetic imagery and symbolism, his love for theatre, and his compositional and organ abilities. The abundant studies of Messiaen’s works deal with the intricacies of his musical language, yet most of these studies barely discuss his theological ideas. Nevertheless, technical analysis of his music poses immense challenges, especially in the domains of melody and harmony. Although my approach is unconventional and do not follow any existing system, I base my technical and theological analyses mainly from Messiaen's technique, his commentaries and his references to the Scriptures. The “Combat de la mort et de la vie” is the heart of Les Corps glorieux in both technical and theological aspects. It is an intricate musical artwork where Messiaen demonstrates his melodic and harmonic developments using his idiosyncratic language, and through symbolism portrays the most complex of all drama according ...

The Effect of Post-exercise Ethanol Consumption on the Acute Hormonal Response to Heavy Resistance Exercise in Women

Date: December 2015
Creator: Budnar, Jr., Ronald G.
Description: The purpose of this study was to examine the hormonal response to acute ethanol ingestion following a bout of heavy resistance exercise in women. Eight resistance trained women completed two identical acute heavy resistance exercise tasks (AHRET). From 10-20 minutes post-AHRET, participants consumed either a grain ethanol or a placebo beverage. Blood was collected before (PRE) and immediately after the AHRET (IP) and then every 20 minutes for five hours. Blood collected after beverage ingestion was pooled into 3 batches (phases: 20-40 minutes, 60-120 minutes, and 140-300 minutes post-exercise) and analyzed for serum total testosterone (TT), free testosterone (FT), insulin-like growth factor-I (IGF-I), human growth hormone (GH), cortisol (COR), and estradiol (E2) concentrations. Circulating concentrations of TT were significantly greater at P20-40 than at PRE, P60-120, and P140-300. Circulating concentrations of FT were significantly greater at P20-40 than at all other times. Circulating concentrations of GH were significantly greater at IP than at PRE, P60-120, and P140-300. Circulating concentrations of COR were significantly greater at P20-40 than at all other times. Additionally, COR concentrations at P140-300 were significantly lower than at all other times. Circulating concentrations of IGF-1 were significantly greater at P20-40 than at P60-120 and P140-300. Circulating concentrations ...

Characterization of Ti-6al-4v Produced Via Electron Beam Additive Manufacturing

Characterization of Ti-6al-4v Produced Via Electron Beam Additive Manufacturing

Date: December 2015
Creator: Hayes, Brian J.
Description: In recent years, additive manufacturing (AM) has become an increasingly promising method used for the production of structural metallic components. There are a number of reasons why AM methods are attractive, including the ability to produce complex geometries into a near-net shape and the rapid transition from design to production. Ti-6Al-4V is a titanium alloy frequently used in the aerospace industry which is receiving considerable attention as a good candidate for processing via electron beam additive manufacturing (EBAM). The Sciaky EBAM method combines a high-powered electron beam, weld-wire feedstock, and a large build chamber, enabling the production of large structural components. In order to gain wide acceptance of EBAM of Ti-6Al-4V as a viable manufacturing method, it is important to understand broadly the microstructural features that are present in large-scale depositions, including specifically: the morphology, distribution and texture of the phases present. To achieve such an understanding, stereological methods were used to populate a database quantifying key microstructural features in Ti-6Al-4V including volume fraction of phases, a lath width, colony scale factor, and volume fraction of basket weave type microstructure. Microstructural features unique to AM, such as elongated grains and banded structures, were also characterized. Hardness and tensile testing were ...

Culturally Proficient Leadership:  Teacher Perceptions of Elementary School Principals in Urban, Title I Schools

Culturally Proficient Leadership: Teacher Perceptions of Elementary School Principals in Urban, Title I Schools

Date: December 2015
Creator: Hendrix, Royond P.
Description: This study examined elementary teachers’ perceptions of their principal’s level of cultural proficiency. Practices for Developing a Culturally Competent School Environment, a survey Camille Smith and adapted by Dr. Mack T. Hines, was completed from a sample size of 119 teachers. The survey contained 35 items, including six constructs: valuing diversity, assessing the culture, managing the dynamics of difference, institutionalizing cultural knowledge and resources, adapting to diversity and inclusiveness. Teachers rated their principal using a Likert scale which consisted of 1 = never uses, 2 = rarely uses, 3 = sometimes uses, 4 = frequently uses, and 5 = always uses. Teachers of various races, ages and years with their principal participated in this study. The study reveals that these variables do not make a statistically significant difference in the teachers’ perception of how proficient they are in valuing diversity, a assessing his/her own culture and institutionalizing cultural knowledge. This quantitative study reveals the variances of statistical significance of teacher demographics: age, gender, years served under current principal and accountability rating of the school. Cultural proficiency is important to the development and maintenance of the necessary relationships among students, teachers, principals and the school community.

Exploring Student Learning on a Short-term, Faculty-led Study Abroad Course Through a Student Development Lens

Date: December 2015
Creator: Garcia, Hope F.
Description: Embarking on a study abroad experience is thought to be a transformational experience for students, and previous researchers have tended to find that the potential benefits of study abroad experiences, including greater conceptual and behavioral intercultural competence, are greater with longer periods abroad. The purpose of this study was to create an intentional learning experience for students who embarked on a short-term study abroad in rural areas of China and to apply faculty intervention of a student development approach to student learning to create a high-impact learning environment for students centered on a service-learning project. This qualitative study gathered primary data from students and instructors during the course through a collection of observation and field notes, student journals, pre- and post-construct tests, and final presentation. Follow-up interviews were conducted 10 months after course completion. Six students participated in this course and study who were from a variety of disciplines and classifications. Five students were female; one was male. Four students were undergraduates; two were graduate students. Student ethnicities included three Caucasians and African American, along with two international students from Mexico and Iran. Key outcomes of this study were that when short-term study abroad faculty members applied creative interventions, students ...

Biological Applications of a Strongly Luminescent Platinum (Ii) Complex in Reactive Oxygen Species Scavenging and Hypoxia Imaging in Caenorhabditis Elegans

Biological Applications of a Strongly Luminescent Platinum (Ii) Complex in Reactive Oxygen Species Scavenging and Hypoxia Imaging in Caenorhabditis Elegans

Date: December 2015
Creator: Kinyanjui, Sophia Nduta
Description: Phosphorescent transition metal complexes make up an important group of compounds that continues to attract intense research owing to their intrinsic bioimaging applications that arise from bright emissions, relatively long excited state lifetimes, and large stokes shifts. Now for biomaging assay a model organism is required which must meet certain criteria for practical applications. The organism needs to be small, with a high turn-over of progeny (high fecundity), a short lifecycle, and low maintenance and assay costs. Our model organism C. elegans met all the criteria. The ideal phosphor has low toxicity in the model organism. In this work the strongly phosphorescent platinum (II) pyrophosphito-complex was tested for biological applications as a potential in vivo hypoxia sensor. The suitability of the phosphor was derived from its water solubility, bright phosphorescence at room temperature, and long excited state lifetime (~ 10 µs). The applications branched off to include testing of C. elegans survival when treated with the phosphor, which included lifespan and fecundity assays, toxicity assays including the determination of the LC50, and recovery after paraquat poisoning. Quenching experiments were performed using some well knows oxygen derivatives, and the quenching mechanisms were derived from Stern-Volmer plots. Reaction stoichiometries were derived from ...

The Countess of Counter-revolution: Madame Du Barry and the 1791 Theft of Her Jewelry

The Countess of Counter-revolution: Madame Du Barry and the 1791 Theft of Her Jewelry

Date: December 2015
Creator: Lewis, Erik Braeden
Description: Jeanne Bécu, an illegitimate child from the Vaucouleurs area in France, ascended the ranks of the Ancien régime to become the Countess du Barry and take her place as Royal Mistress of Louis XV. During her tenure as Royal Mistress, Jeanne amassed a jewel collection that rivaled all private collections. During the course of the French Revolution, more specifically the Reign of Terror, Jeanne was forced to hatch a plot to secure the remainder of her wealth as she lost a significant portion of her revenue on the night of 4 August 1789. To protect her wealth, Jeanne enlisted Nathaniel Parker Forth, a British spy, to help her plan a fake jewel theft at Louveciennes so that she could remove her economic capital from France while also reducing her total wealth and capital with the intent of reducing her tax payments. As a result of the theft, her jewelry was transported to London, where she would travel four times during the French Revolution on the pretext of recovering her jewelry. This thesis examines her actions while abroad during the Revolution and her culpability in the plot. While traveling to and from London, Jeanne was able to move information, money, and ...

Small Town Retail Change in East Texas: an Analysis of Retail Growth, Decline, and Spatial Reconfiguration

Small Town Retail Change in East Texas: an Analysis of Retail Growth, Decline, and Spatial Reconfiguration

Date: December 2015
Creator: Whitaker, Carl W.
Description: In recent years, small towns have experienced declining levels of retail activity attributable to a variety of factors. Previously conducted research identifies a number of these factors such as changing population dynamics, continuously evolving retail practices, locational factors, and an assortment of other macroeconomic factors. Although retail decline is common for many small towns, there are some small towns that have been able to maintain their viability in an ever-changing economic climate. The primary purpose of this research is to better understand what spatial and socio-economic characteristics contribute to retail growth and decline in a series of small towns. This research highlights a selection of small towns across a 14 county area within east Texas. The selection of small towns includes a number of towns with an increasing number of retail establishments as well as a number of towns with decreasing retail establishments over the 14 year study timeframe. Contained within this research is a discussion of small town economic and retail development, as well as findings regarding spatial and socio-economic characteristics as they relate to retail growth and decline in small towns. This research finds that locational characteristics do have an effect on retail growth and decline. The research ...

Identification of Genes Involved in Flocculation by Whole Genome Sequencing of Thauera Aminoaromatica Strain Mz1t Floc-defective Mutants

Identification of Genes Involved in Flocculation by Whole Genome Sequencing of Thauera Aminoaromatica Strain Mz1t Floc-defective Mutants

Date: December 2015
Creator: Prombutara, Pinidphon
Description: Thauera aminoaromatica MZ1T, a floc-forming bacterium isolated from an industrial activated sludge wastewater treatment plant, overproduces exopolysaccharide (EPS) leading to viscous bulking. This phenomenon results in poor sludge settling and dewatering during the clarification process. To identify genes responsible for bacterial flocculation, a whole genome phenotypic sequencing technique was applied. Genomic DNA of MZ1T flocculation-deficient mutants were subjected to massively parallel sequencing. The resultant high-quality reads were assembled and compared to the reference genome of the wild type genome. We identified nine nonsynonymous mutations and one nonsense mutation putatively involved in EPS biosynthesis. Complementation of the nonsense mutation located in an EPS deacetylase gene restored the flocculating phenotype. The FTIR spectra of EPS isolated from the wild-type showed reduced C=O peak of the N-acetyl group at 1665 cm-1 as compared to the spectra of MZ1T floc-deficient mutant EPS, suggesting that the WT EPS was partially deacetylated. Gene expression analysis also demonstrated the deacetylase gene transcript increased before flocculation occurred. The results suggest that the deacetylation of MZ1T EPS is crucial for flocculation. The information obtained from this study will be useful for preventing viscous bulking and wastewater treatment system failure, and may have potential applications in the biotechnology sector for ...
