Statistical Modeling Of The Temporal Dynamics In A Large Scale-Citation Network, Luis Javier Ek Jr.

Graduate Theses and Dissertations

Citation Networks of papers are vast networks that grow over time. The manner or the form a citation network grows is not entirely a random process, but a preferential attachment relationship; highly cited papers are more likely to be cited by newly published papers. The result is a network whose degree distribution follows a power law. This growth of citation network of papers will be modeled with a negative binomial regression coupled with logistic growth and/or Cauchy distribution curve. Then a Barabasi-Albert model, based on the negative binomial models, and a combination of the Dirichlet distribution and multinomial will be …

This mixed methods study adds to the existing literature on distance education, and will provide specific research exploring pre-service teachers’ perceptions of their self efficacy in the context of teacher education. This study is descriptive in nature, and has a dual purpose: to add to the existing knowledge base regarding distance education models and traditional face-to-face delivery models in teacher education, and to inform program designers about the impact of these …

An Analysis Of The Sovereign Citizen Movement: Demographics And Trial Behaviors, Stephen Garrett Smith

Graduate Theses and Dissertations

To date little to no empirical research has been conducted on the Sovereign Citizen Movement (SCM) and how it fits into the broader far-right domestic terrorist movement. The main focus of this study is to determine if there is a significant difference between the SCM and the far-right in their demographic composition, trial strategies, and trial behaviors and whether the SCM should be grouped together with the broader far-right during analysis. Using the American Terrorism Study (ATS), I coded 97 federal court cases involving sovereign citizen defendants (N=150) and ran basic frequencies on demographic and trial behavior variables on the …

Development Of A Biofilm Model For Evaluating Poultry Drinking Water Sanitation Procedures, Pramir Maharjan

Graduate Theses and Dissertations

Enclosed water system has created a minimal sanitation focus leading to biofilm issues which are a source of flock health challenges. A series of in vitro tests were conducted to evaluate biofilm growth on polyvinylchloride (PVC) surfaces when exposed to treated/untreated water sources (test water) that are typically supplied in commercial barns. PVC test coupons (15.16 cm2) were immersed in test water in beakers to grow biofilm. Test water supplies were characterized for microbial, mineral and pH content. Temperature of test water was set at 90 °F (32.2 ᵒC) on d1 and then dropping 1°F each day over 7-day period …

Each subject completed concussion …

“Deliberate Voluptuousness”: The Monstrous Women Of Dracula And Carmilla, Judith Bell

Graduate Theses and Dissertations

Vampire women play a culturally significant role in films and literature by revealing the extent to which deviation from Socially accepted behavior is tolerated. In this thesis, I compare the vampire women of Bram Stoker’s Dracula and J. Sheridan Le Fanu’s Carmilla to their depictions in recent adaptations. In Stoker’s Dracula, the vampire sisters are representative of the shortcomings of 19th century gender roles, especially in regard to women’s communities. In recent adaptations, the vampire sisters’ revealing clothing, promiscuity, and lack of characterization are still closely connected with villainy, and as in Stoker’s novel, the women’s violent deaths in the …

Developmental Traits And Patterns Emerging From Dependent Nurturing Individuals In Narcissistic Relationship, Gregory D. Roberts

Graduate Theses and Dissertations

The concept of personality theories and personality disorders has developed in modern times from deep roots in philosophy and psychodynamic theory. This theory orientation has evolved to diagnostic and treatment application. Much of the literature has focused on personality disorders as independent and singular constructs. Phenomenological discussions and deeper understandings of dysfunctional relationships between the two specific disorders of dependent personality and narcissistic personality are lacking. Significant longsuffering, abusive, and pathological behaviors at times are observed among dependent personality types in bad relationships. The objective of this study was to gather data from a sample of dependent types to discover …

Divining The Southwest: Liminality, Pragmatism, And Regionalism In "Death Comes For The Archbishop", Alex C. Blomstedt

Graduate Theses and Dissertations

This work aims to explore the themes of pragmatism and liminality, particularly as they pertain to spirituality, in Willa Cather’s Death Comes for the Archbishop. By taking an interdisciplinary critical approach to the novel, I will synthesize its spiritual affect into a sensibility called “pragmatic liminality.” Finally, I will connect this sensibility to other works in the Southwestern literary canon and elucidate the foundational importance that pragmatic liminality has to the Southwestern “sense of place” and its role in the larger narratives of regionalism in American literature.

[Re]Visiting The Rime: A Case Study Of Adaptation As Process And Product With The Rime Of The Ancient Mariner, Sally Ferguson

Graduate Theses and Dissertations

This thesis combines adaptation theory with ecology to examine Samuel Taylor Coleridge's Rime of the Ancient Mariner (1798) and its adaptations; it argues further combinations of adaptation with evolutionary theory and ecological ideas could allow for a better interpretation of many texts. The adaptation Rime of the Modern Mariner (2011) by Nick Hayes and the appropriation Perelandra (1943) by C.S. Lewis will also be present in individual chapters to examine the texts' interactions with each other as they evolve and how each work represents the combined theory.

Men Who Coach Women, Shannel Blackshear

Graduate Theses and Dissertations

Although Title IX helped to shape athletics in educational settings, the legislation also transformed the world of coaching. Due to the growing demand for competitive female athletics at the collegiate level, the need for qualified individuals to coach women’s sports continues to grow. As colleges and universities continue to create women’s athletic opportunities, coaching collegiate female teams has become equally competitive to coaching male athletes in terms of pay, benefits, compensation packages, and national attention (Welch & Sigelman, 2007). Despite the fact that 57% (Pilon, 2015), of female collegiate athletic teams are coached by male coaches, there is a gap …

Cloning, Fed-Batch Expression And Purification Of A Novel Anti-Candida Peptide And Development Of A Cleavage Resistant Variant Of Green Fluorescence Protein, Rudra Palash Mukherjee

Graduate Theses and Dissertations

This work illustrates that the intelligent design of a bioprocess for the production of peptides of various length is possible by having a prior knowledge of desired product, cell line, fermentation conditions, and choices for downstream recovery. Cloning, expression, and recovery of a novel 12-mer anti-Candida peptide served as an illustrative case for a proposed Escherichia coli platform. The antifungal peptide, expressed as a fusion to GFPUV during high call density fed-batch, was recovered from cell lysate, concentrated using ion exchange chromatography, and finally cleaved with cyanogen bromide. The platform was capable of producing active peptide capable of arresting the …

Shared Perspectives Of Divided Space: Perceptions Of The Urban Environment Among Jerusalemites, Andie Duplantis

Graduate Theses and Dissertations

Multidisciplinary research and philosophical discourse have long explored the complex relationship between the objective environment and subjective human perception. No two humans perceive, experience, and form attitudes about the same phenomenon in exactly the same way. Individual demographics (sex, age) and group identity (culture, religion, ethnicity, political ideology) have been shown to have a profound effect on perception of phenomena; research has also focused on the effect of the physical environment itself. Differences in perception, experience, and resulting behavior have great implications for governance, particularly in regards to planning and development. Recognizing these differences, modern urban planning increasingly seeks to …

The Ccaat-Binding Factor Dependent Regulation Of The Oxidative Stress Response In Candida Albicans, Ananya Chakravarti

Graduate Theses and Dissertations

The success of Candida albicans as an opportunistic human pathogen has been attributed to several factors, including the ability to survive in limiting iron environments and the ability to evade the respiratory burst of human macrophages and neutrophils. The goal of this research is to elucidate the role of the CCAAT-binding factor in the oxidative stress response of Candida albicans. Prior whole genome microarray studies performed in our lab compared the gene expression of a wild type Candida albicans strain versus a hap5Δ strain under iron-limiting growth conditions. Among the differentially regulated genes, CTA1, encoding catalase, had a four-fold higher …

Genotoxicity Of Graphene In Escherichia Coli, Ananya Sharma

Rapid advances in nanotechnology necessitate assessment of the safety of nanomaterials in the resulting products and applications. One key nanomaterial attracting much interest in many areas of science and technology is graphene. Graphene is a one atom thick carbon allotrope arranged in a two-dimensional honeycomb lattice. In addition to being extremely thin, graphene has several extraordinary physical properties such as its exceptional mechanical strength, thermal stability, and high electrical conductivity. Graphene itself is relatively chemically inert and therefore pristine graphene must undergo a process called functionalization, which is combination of chemical and physical treatments that change the properties of graphene, …

Assessment Of Microbial And Growth Response Of Broilers Fed A Commercial Prebiotic, Sang In Lee

Graduate Theses and Dissertations

Prebiotic refers to nondigestible food ingredients that enhance the health of the host by selectively promoting one or more number of beneficial bacteria. Gibson and Roberfroid (1995) initially described prebiotics as compounds that neither hydrolyzed nor absorbed in upper part of the gastrointestinal tract, selectively stimulates growth of beneficial bacteria, enhance health of the host and able to amend microorganism population to healthier states. Prebiotics are particularly attractive supplements in animal production due to their variety of effects including production of short chain fatty acids, pH amendments and suppression of pathogen colonization. In addition, prebiotics were emphasized as antibiotic alternatives …

Movements, Music, And Meaning: A Comparative Analysis Of Cultural Narratives In Vietnam Era And Post-9/11 Anti-War Music, Jonathan Nathaniel Redman

Graduate Theses and Dissertations

This thesis examines the presence of widely circulating cultural narratives in the lyrics of approximately eighty anti-war songs from the Vietnam and post-9/11 eras. Unlike prior movements and music research, this thesis privileges culture over movements and views movements as cultural antennae both picking up on trends and cultural narratives, and broadcasting their own altered cultural meanings back into the “cultural airways.” It sees music as a cultural medium which acquires cultural meanings from its surroundings, alters those meanings, synthesizes new ones, and perpetuates old ones. Drawing on comparative and narrative analysis approaches informed by grounded theory techniques, this thesis …

Nutritional Deficiencies During The Harvest Season According To Household Consumption And Level Of Nutritional Knowledge: A Case Study Of Northern Mozambique, Maggie Jo Hansen

Graduate Theses and Dissertations

Mozambique is classified as a low income country, the lowest development classification defined by the World Bank. It is underdeveloped in food security, agricultural production, and nutritional status, and research shows its residents are not foreign to poverty and malnutrition. Low protein, starchy foods (maize, rice, wheat, cassava) comprise the majority of the Mozambican diet; these starchy foods are the most available for consumption. Although availability impacts diet, educational barriers may also threaten the knowledge of nutrition and perceptions of healthy foods. Illiteracy and lack of education are extreme challenges to disseminating nutritional education efforts in the rural Nampula region. …

The Effects Of Brief, Passive Psychoeducation On Suicide Literacy, Stigma, And Attitudes Toward Help-Seeking Among Latino Immigrants Living In The United States, Aubrey Renee Dueweke

Graduate Theses and Dissertations

Latino immigrants drastically underutilize mental health treatment services compared to other ethnic groups, despite rates of mental illness that are comparable to those observed among the general population. With regards to suicidal behavior specifically, twice as many Latino suicide attempters do not seek or receive psychiatric services in the year prior to attempting suicide, compared to non-Latino White attempters. The main objective of this study was to investigate whether provision of brief, passive psychoeducation in the form of a brochure could increase suicide literacy (i.e., recognizing suicidal behavior, understanding risk factors and causes of suicidal behavior), reduce stigma toward suicidal …

Sirex nigricornis F. (Hymenoptera: Siricidae) is a native woodwasp in eastern North America that inhabits dead and dying pine trees during its univoltine development. Sirex noctilio is native to Eurasia and North Africa and was discovered in the northeastern United States in 2004 after a century of accidental introductions across the Southern Hemisphere. Since then, it has spread to seven states and southern Ontario. There is concern about its potential to negatively affect the multi-billion dollar pine timber industry of the southeastern United States. Effective monitoring tools are necessary to track the spread and establishment of S. noctilio. Deladenus siricidicola …

Dandy As Disease: Gender Hygiene And British Nineteenth-Century Literature, Sharon Louise Fox

Graduate Theses and Dissertations

“Dandy as Disease: Gender Hygiene and British Nineteenth-century Literature” explores the link between the nineteenth-century dandy, ideas of hegemonic masculinity, and Walter Besant’s The Revolt of Man, a dystopian text in which women have usurped all traditionally-masculine roles, while men are the caretakers and manual workers. The first chapter deals with the historical role of the dandy in the nineteenth-century and how he might be viewed as the cause of the fall of Britain. The second chapter revolves around Besant’s novel, exploring how men are shown to be at fault for Britain’s fall in the eyes of the rest of …
