Despite its generally agreed importance, very little has been written about The Apostles. Even among the extant publications that address The Apostles, scholars have focused on its history and development, its reception, or analytical descriptions of its surface themes. The aim of this study will therefore be to provide neither a biography of Elgar, nor an account of the genesis of the work, but to analyze The Apostles in a manner that will achieve a deeper understanding of the oratorio. Chapter 1 explores the complexities that surround Judas and the different ways in which he was perceived throughout history. Then, through my analysis of the surface motives in Chapter 2 and their significance in relation to the large-scale harmonic structure in Chapter 3, I will suggest that Elgar does not denigrate Judas as the betrayer of Christ in The Apostles, but rather depicts him as a tragic yet crucial figure in achieving the redemption of mankind, and through this Judas himself is redeemed.

This dissertation investigates data reduction strategies from a signal processing perspective in centralized detection and estimation applications. First, it considers a deterministic source observed by a network of sensors and develops an analytical strategy for ranking sensor transmissions based on the magnitude of their test statistics. The benefit of the proposed strategy is that the decision to transmit or not to transmit observations to the fusion center can be made at the sensor level resulting in significant savings in transmission costs. A sensor network based on target tracking application is simulated to demonstrate the benefits of the proposed strategy over the unconstrained energy approach. Second, it considers the detection of random signals in noisy measurements and evaluates the performance of eigenvalue-based signal detectors. Due to their computational simplicity, robustness and performance, these detectors have recently received a lot of attention. When the observed random signal is correlated, several researchers claim that the performance of eigenvalue-based detectors exceeds that of the classical energy detector. However, such claims fail to consider the fact that when the signal is correlated, the optimal detector is the estimator-correlator and not the energy detector. In this dissertation, through theoretical analyses and Monte Carlo simulations, eigenvalue-based detectors …

Titanium dioxide nanoparticles (TiO2-NP) are one of the most abundantly utilized nanomaterials in the world. Studies have demonstrated the mechanism of acute toxicity in TiO2-NP to be the production of reactive oxygen species (ROS) leading to oxidative stress and mortality in exposed organisms. It has also been demonstrated that the anatase crystalline conformation is capable of catalyzing the cleavage of water molecules to further increase the concentration of ROS in the presence of ultraviolet radiation. This photoenhanced toxicity significantly lowers the toxicity threshold of TiO2-NP to environmentally relevant concentrations (ppb). The goal of this study was to determine whether dietary uptake and accumulation of TiO2-NP in the aquatic filter feeder Daphnia magna resulted in photoenhanced toxicity. D. magna and S. caprincornatum were exposed to aqueous solutions of 20ppm and 200ppm TiO2-NP for 24hrs and then transferred to clean moderately hard water. Samples were taken at various time points, dried, and TiO2 quantified using ICP-MS. Toxicity assays were run on D. magna using three TiO2-NP (20ppm, 200ppm) exposure protocols and two ultraviolet radiation treatments. The first exposure group was exposed to aqueous solutions of TiO2-NP for the duration of the test. The second exposure group was exposed to TiO2-NP for an …

Ground source heat pump (GSHP) uses earth’s heat to heat or cool space. Absorbing heat from earth or rejecting heat to the earth, changes soil’s constant temperature over the multiple years. In this report we have studied about Soil temperature change over multiple years due to Ground loop heat exchanger (GLHE) for Zero Energy Research Laboratory (ZØE) which is located in Discovery Park, University of North Texas, Denton, TX. We did 2D thermal analysis GLHP at particular Depth. For simulation we have used ANSYS workbench for pre-processing and FLUENT ANYS as solver. TAC Vista is software that monitors and controls various systems in ZØE. It also monitors temperature of water inlet/outlet of GLHE. For Monitoring Ground temperatures at various depths we have thermocouples installed till 8ft from earth surface, these temperatures are measured using LabVIEW. From TAC Vista and LabVIEW Reading’s we have studied five parameters in this report using FLUENT ANSYS, they are; (1) Effect of Time on soil Temperature change over Multi-years, (2) Effect of Load on soil temperature change over Multi-years, (3) Effect of Depth on soil temperature change over Multi-years, (4) Effect of Doubling ΔT of inlet and outlet of GLHE on soil temperature change over …

Recent developments in the field of education have led to a proliferation of educational technologies (or “ed-tech”), yet access to educational content for students with special needs remains a challenge. This research study aims to assess the current state of accessibility in emerging ed-tech and to identify barriers in enabling educational content to be born accessible. Detailed discussions with various ed-tech platforms revealed less of a need for technical tools, but a more prevailing need for knowledge and education around accessibility – what it means and how best to incorporate accessibility into their platforms. The more experienced teams advocate incorporating accessibility into product development right from the design phase, while the younger teams expressed challenges in navigating accessibility laws and the dire need for easy-to-follow guidelines and best practices. A detailed review of educators' content creation processes reveals multiple dependencies in the ecosystem of ed-tech where partnerships and compatibilities are crucial in enabling accessibility throughout the process. Likewise, an urgent need exists for increasing awareness of accessibility among instructors authoring educational content using emerging ed-tech.

Sunken Monadnock is a scripted combination of three modular musical surfaces. The word “surface” is borrowed from Morton Feldman, who compared the aural surface of music to the canvases of the action painters of the American Abstract Expressionists, and contrasted it with the work’s subject, or organizational structure. Composers’ transition toward a focus on surface through indeterminate compositional techniques, according to Feldman, parallels the development of modernist abstract art. “Sunken Monadnock: Composing with Visual Metaphors” is a companion critical essay that takes the surface/subject metaphor as a starting point for analyzing Sunken Monadnock.Other visual metaphors that inspired Sunken Monadnock, and are discussed in the essay, include Shakir Hassan Al Said’s mystical semiotics, Jasper Johns’s crosshatch prints, and Wassily Kandinsky’s theory of abstraction. The circle and spiral, especially, play influential roles in Sunken Monadnock as reflected by musical applications of repetition, rotation, compression/rarefaction, and endlessness. The void in the circle’s center also comes into play. The nature of the work’s formal counterpoint requires an innovative approach to the score, which consists of five sections, each of which reflects a different approach to the aural surface (i.e., to the traversal of time). The two outer sections are traditionally scored, but the three …

This dissertation examines the role of aesthetic activity in the pursuit of political agency in readings of several of Shakespeare’s plays, including Hamlet (1600), A Midsummer Night’s Dream (1595), The Tempest (1610), the history plays of the second tetralogy (1595-9), Julius Caesar (1599), and Coriolanus (1605). I demonstrate how Shakespeare models political subjectivity—the capacity for individuals to participate meaningfully in the political realm—as necessitating active aesthetic agency. This aesthetic agency entails the fashioning of artistically conceived public personae that potential political subjects enact in the public sphere and the critical engagement of the aesthetic and political discourses of the subjects’ culture in a self-reflective and appropriative manner. Furthermore, these subjects should be wary auditors of the texts and personae they encounter within the public sphere in order to avoid internalizing constraining ideologies that reify their identities into forms less conducive to the pursuit of liberty and social mobility. Early modern audiences could discover several models for doing so in Shakespeare’s works. For example, Hamlet posits a model of Machiavellian theatricality that masks the Prince's interiority as he resists the biopolitical force and disciplinary discourses of Claudius's Denmark. Julius Caesar and Coriolanus advance a model of citizenship through the plays’ nameless …

Alexander Scriabin (1872-1915) stands as one of the most unconventional twentieth-century Russian composers, particularly with respect to his piano works. The overwhelming majority of Scriabin's compositions—sixty-seven of his seventy-four published works—were written for solo piano. His etudes from 1905 forward are revolutionary, especially compared with his earlier Chopinesque style. Among Scriabin’s twenty-six etudes, his Op.49, No. 1 (1905), Op.56, No. 4 (1908) and the last three etudes of Op.65 (1912) date from his last period of composition. In the Op.49 etude, Scriabin started to abandon traditional tonality. He omitted the key signature altogether in the Op.56 etude. The final three etudes of Op.65 feature constant dissonances on ninths, sevenths and fifths. Alexander Scriabin’s last five etudes represent the culmination of his compositional development and innovations at the piano. Several factors coalesce in these etudes, including unusual harmony, bichords, non-tonal hierarchy, and structural symmetry. Most of these factors derive in some fashion from Scriabin’s increasing reliance upon the so-called “mystic chord” in his late works. This study will illustrate how Scriabin explored new sonorous and aesthetic ideas in his late etudes by means of these innovations.

The Abraham solvation parameter model is a good approach for analyzing and predicting biological activities and partitioning coefficients. The general solvation equation has been used to predict the solute property (SP) behavior of drug compounds between biological barriers. Gas chromatography (GC) retention time can be used to predict molecular descriptors, such as E, S, A, B & L for existing and newly developed drug compounds. In this research, six columns of different stationary phases were used to predict the Abraham molecular descriptors more accurately. The six stationary phases used were 5% phenylmethyl polysiloxane, 6% cyanopropylphenyl 94% dimethylpolysiloxane, 5% diphenyl 95% dimethylpolysiloxane, 100% dimethylpolysiloxane, polyethylene glycol and 35% diphenyl 65% dimethylpolysiloxane. Retention times (RT) of 75 compounds have been measured and logarithm of experimental average retention time Ln(RTexp) are calculated. The Abraham solvation model is then applied to predict the process coefficients of these compounds using the literature values of the molecular descriptors (Acree Compilation descriptors). Six correlation equations are built up as a training set for each of the six columns. The six equations are then used to predict the molecular descriptors of the illegal drugs as a test set. This work shows the ability to extract molecular information from …

Theatre is widely unrecognized for the compelling influence it has held in society throughout history. In this thesis, I specifically examine the implications surrounding the social protest theatre of black and Jewish American minority communities in the first half of the twentieth century. I discuss how their historical circumstance, culture, and idiosyncratic natures caused them to choose agitated propaganda theatre as an avenue for protest. I delve into the similarities in circumstance, but their theatre case studies separate the two communities in the end. I present case studies of each community, beginning with anti-lynching plays of the 1920s that were written by black American playwrights both in response to white supremacist propaganda theatre and to assert a dignified representation of the black community. However, their plays and protest movement never developed a larger popular following. My next minority theatre case study is an examination of 1930s Jewish labor drama created in protest of popular anti-Semitic theatre and poor labor conditions. The Jewish community differs from the black community in their case because the racist propaganda was produced by a man who was Jewish. Another difference is that their protest theatre was on the commercial stage by this point because of …

The purpose of this study is to examine the structure of neurobehavioral symptoms in service members with physical and/or psychological trauma to determine the diagnostic specificity of these symptoms. Previous literature has demonstrated that orthopedic injured, mild traumatic brain injury (MTBI), and healthy controls shared similar levels of postconcussive symptom complaints, which suggest that postconcussion-like symptoms are not unique to MTBI. To the best of my knowledge, this is the first study examining this phenomenon in a sample of recently redeployed service members. Dimensional analysis of the PCL-C and NSI using SEM did not produce a model that was consistent with previous literature and principle component analyses did not produce a simple solution for posttraumatic stress or neurobehavioral symptoms. Thus, the study does not provide evidence for construct validity for either instrument. Implications for these findings are that clinicians need to be aware that these instruments may not be measuring coherent constructs within this population as purported and should judiciously interpret and report the results of these instruments.

The current study examines the influences of blog type and blog message type on consumers’ perceptions of brand credibility and brand similarity. Additionally, the study seeks to understand the interaction effects of blog type and message type on brand credibility and brand similarity and on consumer engagement with a blog. The findings reveal that message type, specifically product message, is an important consideration when marketers want to illustrate similarities between the brand and consumers. Additionally, it was found that product messages should be considered when encouraging consumer engagement with a blog. However, blog type did not have an effect on consumer perceptions of brand credibility and similarity or consumer engagement.

The purpose of this research is to examine the longevity of the stereotype of the tragic mulatto in American film history. Specifically, my research focuses on the portrayals and perceptions of biracial actresses. Media informs, entertains, and influences how we, and especially youth, self-identify and interact with others. This research focuses on the portrayal of biracial actresses throughout film history. It is also important in its investigation of the perpetuation of the one-drop rule. In this research, I will examine if historical stereotypes of tragic mulatto are apparent in contemporary Hollywood film. The methodologies used in this research include a content analysis of films with biracial actresses and an online survey of respondents’ perceptions of four actresses. Statistical techniques used for analysis include ordinary least square regression and multinomial logistic regression. Findings suggest that the tragic mulatto stereotype is not blatant in contemporary Hollywood film, but issues of colorism may be apparent.

The details of dye sensitized solar cells was explained and phenothiazine and porphyrin based dyes were synthesized for use in DSSCs. DSSCs offer a unique and cost effective method of renewable energy. DSSCs are characterized through various tests, with the overall efficiency, η, bearing the greatest importance. Incident photon to current conversion efficiency, or IPCE, is also another important characterization of DSSCs. Effect of positioning of the cyanoacrylic acid anchoring group on ring periphery of phenothiazine dye on the performance of dye sensitized solar cells (DSSCs) is reported. The performances of the cells are found to be prominent for solar cells made out of Type-1 dyes compared to Type-2 dyes. This trend has been rationalized based on spectral, electrochemical, computational and electrochemical impedance spectroscopy results. Free-base and zinc porphyrins bearing a carboxyl anchoring group at the para, meta, or ortho positions of one of the meso-phenyl rings were synthesized for DSSCs. Photoelectrochemical studies were performed after immobilization of porphyrins onto nanocrystalline TiO2. The performance of DSSCs with the porphyrin anchoring at the para or meta position were found to greatly exceed those in the ortho position. Additionally, zinc porphyrin derivatives outperformed the free-base porphyrin analogs, including better dye regeneration efficiency …

This creative thesis collects five fictional stories, as well as a critical preface entitled “Fractals and the Gestalt: the Hybridization of Genre.” The critical preface discusses genre as a literary element and explores techniques for effective genre hybridization. The stories range from psychological fiction to science fiction and fantasy fiction. Each story also employs elements from other genres as well. These stories collectively explore the concept of the other and themes of connection and ostracization.

This thesis discusses the decline of the Venetian nobility, the collapse of the Venetian economy, and the political results of the surrender of the Venetian Republic to Napoleon Bonaparte in 1797. Topics include the formation of Venice, Venetian domination of trade, the class system in Venice prior to 1797, the collapse of the aristocracy, feudalism in Venice, Venice’s presence in the Adriatic and Aegean seas, and the rise of the middle class within the provisional democratic government. Very few historians have attempted to research the provisional democracy of Venice and how the political and class structure of Venice changed as a result of the collapse of the Republic in 1797. Using primary sources, including government documents and contemporary histories, one can see how the once dominant noble class slowly fell victim to economic ruin and finally lost their role in the political leadership of Venice all together. During this same period, the middle class went from only holding secretarial jobs within the government, to leaders of a modern democratic movement. On top of primary research, several secondary sources helped in explaining the exclusivity of the noble class and their journey from economic dominance to economic ruin and the administrative consequences …

Plants possess unique features in many aspects of development. One of these features is seen in cell wall placement during cytokinesis, which is determined by the position of the preprophase band (PPB) and the subsequent expansion of the phragmoplast that deposits the new cell wall. During phragmoplast expansion, the phragmoplast tracks to the cortical division site, which was delineated by the PPB. Thus the position of the PPB determines the orientation of the division plane. In Arabidopsis thaliana, TONNEAU2 (TON2) is required for PPB formation and has been shown to interact with a type A subunit of the PP2A phosphatase in the yeast two-hybrid system. In Arabidopsis tonneau2 (ton2) mutants, abnormalities of the cortical microtubule cytoskeleton, such as disorganization of the interphase microtubule array and lack of PPB formation before mitosis markedly affects cell shape and arrangement as well as overall plant morphology. Loss of dcd1/add1, the maize ton2 homologues gives rise to a similar phenotype in Zea mays. The TON2 protein has two EF hand domains which are calcium-binding sites. Since calcium has been known to play key roles in several areas of plant functioning, the following question was raised: “Does calcium binding contribute to the localization and function …

This project explores the representation of white, American masculinity within the Hollywood bromantic comedy cycle. By analyzing three interrelated components (close homosociality, infantilization, and relationship to patriarchy) of the model of masculinity perpetuated by this cycle of films, this study reveals the hegemonic motives therein. Despite the representation of a masculinity nervously questioning its position within the romantic comedy narrative and the broader patriarchal structure, the results of this representation are, ultimately, regressive and reactionary. Cultural gains made concerning gender, sexuality, and race are doubled back upon in a cycle of films that appeal to regressive modes of misogyny, homophobia, and racism still present in Hollywood filmmaking, and the hegemony of white, patriarchal heteronormativity is rigorously maintained.

In the world we live in today, having a social media account such as Facebook, LinkedIn, Twitter, or Google+ has become deeply ingrained in our society. The old way of networking with who you knew or who knew your family is no longer in play for many people. In the times in which we live, much personal and professional networking is completed via social media. The old way of networking had unwritten rules of engagement which, basically, were to be respectful and not cause any embarrassment within the network. Rules for best practice engagement are still evolving for this new way of using social media for personal and professional networking, which is the premise for the current study which addresses: the gap in U.S. university social media policies, with regard to teaching and learning. In order to gauge the policy interlude, a sample of over 49 U.S. university social media policies were gathered for a comprehensive document analysis. The Google search engine was used to find the policies, next the qualitative software NVivo10 was used to procure and analyze the policies. Additionally, triangulation was performed by three member checking volunteer investigators. The results of the study, disclosed that current policies …
