Modeling Risk For Sexually Transmitted Infections In Women In A Court-Ordered Substance Treatment Program, Frances Deavers

Electronic Theses and Dissertations

Developing a comprehensive model of Sexually Transmitted Infection (STI) risk factors and their inter-relationships is vital to improving methods of risk identification and treatment delivery. The CDC posed three general categories that may serve as a framework for such a model: sexual network, individual behavior, and social/ structural risk. None of the extant risk models incorporate measures from all three categories. Additionally, none of these models, generally focused on individual behavior, use medical data on infection as their outcome variable. This is problematic because the ultimate outcome of infection is also influenced by sexual network and social/ structural variables, in …

Talking Back: Mathematics Teachers Supporting Students' Engagement In A Common Core Standard For Mathematical Practice: A Case Study, Mercedes Sotillo Turner

Electronic Theses and Dissertations

The researcher in this case study sought to determine the ways in which teachers support their students to create viable arguments and critique the reasoning of others (SMP3). In order to achieve this goal, the self-conceived classroom roles of two teachers, one experienced and one novice, were elicited and then compared to their actualized roles observed in the classroom. Both teachers were provided with professional development focused on supporting student engagement in SMP3. This professional development was informed by the guidelines that describe the behaviors students should exhibit as they are engaged in the standards for mathematical practice contained in …

The Relationship Of State Political Instability And Economic Failure To Predatory Organized Crime In Multiple Nations: A Global Comparative Anaylsis, Terrance Ruth

Electronic Theses and Dissertations

This dissertation examines the relationship of political instability and economic failure to predatory organized crime in multiple nations. This is an important issue since each year the increase in predatory crime networks contributes to international economic failure, security risks, and the spread of organized crime. In an effort to understand the relationship between state failure and economic failure on the one hand, and organized crime on the other, this study will seek to address three goals. First, the study tests the degree to which variables that imply economic failure and state failure correlate with predatory organized crime. Second, the study …

Perceptual Analysis Of Prolonged Vowels In Adolescent And Young Adults With Friedreich's Ataxia, Tara Varsallone

Electronic Theses and Dissertations

The purpose of this study was to conduct perceptual analyses, using the initial two-second portions, of prolonged vowels /a/, /i/, and /o/. Two groups of adolescents and young adults were analyzed- one group consisting of 20 individuals with Friedreich's ataxia who were compared to 20 individuals with normal voice (control participants). A trained group of 10 graduate students listened to 132 vowel samples (3 vowels X 40 participants, + 12 samples (10%) for reliability purposes) for a total of 132 perceptual judgments. The students listened to the samples which were randomized onto Dell computers (Optiplex 755) and played through headphones …

Structural And Functional Studies Of Glycine Riboswitches And Development Of Fab Chaperone Assisted Rna Crystallography, Eileen Sherman

Electronic Theses and Dissertations

The glycine riboswitch is a structured RNA found upstream of genes in mRNA transcripts in many bacteria, functioning as a biofeedback gene regulator. Upon binding glycine, a complete RNA transcript including gene sequences is transcribed, effectively turning on gene expression. In an effort to understand the intricacies of its functioning, many mutants of the riboswitch were made and characterized during Ph. D. work, resulting in discovery of a P0 duplex/kink-turn motif involving a few nucleotides upstream of the established glycine riboswitch sequence which changed its ligand binding characteristics (Chapter 1). Previously, the two aptamers of the riboswitch were thought to …

Failing The Failed: A Treatise On The Need For A Research Based Pedagogical Approach To Credit Recovery, Kelly Scott

Electronic Theses and Dissertations

The purpose of this dissertation in practice is to address the problem of online credit recovery. Although online enrollments have skyrocketed in recent years and all preliminary research indicates a large percentage of those enrollments are from students seeking credit recovery, much of the curriculum currently being offered is not research-based. Following a literature review focused on the history of credit recovery as well as successful current methods, we designed CRIT (Credit Recovery Instructional Treatment), a research-based approach to curriculum design for credit recovery. CRIT is a standards based curriculum relying on criterion based assessments. This approach was then applied …

Alleyne On The Ground: Factfinding That Limits Eligibility For Probation Or Parole Release, Nancy J. King, Brynn E. Applebaum

Vanderbilt Law School Faculty Publications

This article addresses the impact of Alleyne v. United States on statutes that restrict an offender’s eligibility for release on parole or probation. Alleyne is the latest of several Supreme Court decisions applying the rule announced in the Court’s 2000 ruling, Apprendi v. New Jersey. To apply Alleyne, courts must for the first time determine what constitutes a minimum sentence and when that minimum is mandatory. These questions have proven particularly challenging in states that authorize indeterminate sentences, when statutes that delay the timing of eligibility for release are keyed to judicial findings at sentencing. The same questions also arise, …

Eurocentrism, Modernity And Chinese Sociality : An Ethnographic Study Of Everyday Socio-Cultural Life In New-Millennium China, Tung Yi Kho

Lingnan Theses

This dissertation seeks to contribute to our understanding of Eurocentrism, Modernity,and their impacts on traditional Chinese cultural formations. It is based on ethnographic research conducted in Shenzhen, South China and Qinghai, West China, and explores the impacts of Chinese modernization on everyday forms of sociality.

I conceive of Eurocentrism foremost as an Ontology, a mode-of-being grounded in a cosmology about the nature of reality and human being-and-becoming in the world. I argue that because Eurocentrism is an ontology predicated on materialism and individualism - “matter” being the basis of reality and the “individual”, the fundamental unit of society, respectively - …

A Study Of Authentic Leadership Adopting The Job Demands And Resources Approach In Predicting Work-Related Flow And Job Performance, Yiqing Wang

Lingnan Theses

The authentic leadership model posits that authentic leaders can foster personal development of their subordinates in order to produce better job outcomes. The current study has investigated authentic leadership using the job demands and resources (JD-R) approach to examine how leaders’ authenticity can empower employees in terms of resources-building (e.g. PsyCap, supervisor support); and to examine how these resources can offset negative stressors (e.g. work overload, emotional demands) so that employees may achieve a peak psychological state of flow (Bakker, 2005, 2008) and better job performances. To date, very few studies have tried to explain authentic leader behaviors in the …

Ar Physics: Transforming Physics Diagrammatic Representations On Paper Into Interactive Simulations., Yao Zhou

Electronic Theses and Dissertations

A problem representation is a cognitive structure created by the solver in correspondence to the problem. Sketching representative diagrams in the domain of physics encourages a problem solving strategy that starts from 'envisionment' by which one internally simulates the physical events and predicts outcomes. Research studies also show that sketching representative diagrams improves learner's performance in solving physics problems. The pedagogic benefits of sketching representations on paper make this traditional learning strategy remain pivotal and worthwhile to be preserved and integrated into the current digital learning landscape. In this paper, I describe AR Physics, an Augmented Reality based application that …

An Examination Of Job Analysis: Developing Interdisciplinary Strategies In Human Resource Management Facilitative Of Mitigating Propensities Of Teacher Attrition, Julio Devere

Electronic Theses and Dissertations

Despite repeated attempts by school administrators, policymakers and researchers to diagnose and correct rising occurrences of teacher turnover, there has been little change in the actual efforts to retain teachers in academy organizations. In response, this study was conducted to describe process constraints within the academy organization that are responsible for managing teacher turnover. To provide a description of current teacher retention efforts by school administrators, a survey instrument was administered to school teachers in the State of Florida. The population sample was dispersed throughout the entire state and closely reflected the demographics of Florida school teachers. The survey addressed …

A Thomistic Critique Of The Ethics Of Alasdair Macintyre, Marcus Otte

Electronic Theses and Dissertations

Alasdair MacIntyre argues in favor of a historicist Thomism in ethics and political philosophy. In his theory, sociological categories take up much of the space traditionally occupied by metaphysics. This peculiar feature of MacIntyre's Thomism, and its merits and demerits, is already a subject that has been taken up by many critics. In this thesis, these criticisms are supplemented and unified by identifying what is perhaps the most fundamental difficulty with MacIntyre's ethics: his version of Thomism is problematic because it treats epistemology as first philosophy. This misstep compromises MacIntyre's ability to provide a defense of moral objectivity, while also …

Evaluation Of A Digitally-Automated Alcohol Curriculum Designed To Alter Expectancies And Alcohol Use In First Year College Students, Amy Schreiner

Electronic Theses and Dissertations

High-risk alcohol consumption remains a primary public health concern for students on college campuses. In response to this concern the National Advisory Council of the National Institute on Alcohol Abuse and Alcoholism created a task force to identify and recommend strategies to aid college administrators in implementing effective alcohol programming at their institutions. While most administrators report being aware of these recommendations, many have not successfully implemented empirically supported interventions on their campuses. One significant barrier is the cost and difficulty of training and hiring skilled staff to implement these interventions. Of the strategies identified as effective, challenging alcohol expectancies …

How Many Are Out There? A Novel Approach For Open And Closed Systems, Zia Rehman

Electronic Theses and Dissertations

We propose a ratio estimator to determine population estimates using capture-recapture sampling. It's different than traditional approaches in the following ways: (1) Ordering of recaptures: Currently data sets do not take into account the "ordering" of the recaptures, although this crucial information is available to them at no cost. (2) Dependence of trials and cluster sampling: Our model explicitly considers trials to be dependent and improves existing literature which assumes independence. (3) Rate of convergence: The percentage sampled has an inverse relationship with population size, for a chosen degree of accuracy. (4) Asymptotic Attainment of Minimum Variance (Open Systems: (=population …

Electric Power Resource "Shuffling" And Subnational Carbon Regulation: Looking Upstream For A Solution, Jim Rossi, Andrew J.D. Smith

Vanderbilt Law School Faculty Publications

"Resource shuffling" occurs when different subnational approaches to carbon regulation create variations in the costs of production across jurisdictions. California is the most aggressive jurisdiction in the United States to address climate change and has adopted a cap & trade program for its greenhouse gas (GHG) emissions. This Article addresses the resource shuffling issue presented by California's cap-and-trade program and evaluates the merits of various legal and regulatory solutions to the problem.

Deadly Premonition: Does Terrorist-Leader Psychology Influence Violence Lethality?, Clayton Besaw

Electronic Theses and Dissertations

This thesis seeks to address a theoretical and empirical gap within terrorism studies, and more specially the study of terrorist-group lethality. This research updates a model of terrorist-group lethality by including terrorist-leader psychology as an individual-level variable in predicting terrorist-group lethality. Terrorist-leader statements were analyzed by using two novel coding schemes called Operational Code and Leadership Trait Analysis to create quantified measurements of leader cognitive beliefs and personality traits. The empirical portion of this study utilizes pooled cross-sectional time-series data within the framework of fixed effects and multi-level estimation models. The results find that terrorist-leader psychology, and more specifically Instrumental …

Down In The Mouth: Homelessness And Oral Health, Jessica Kleinberger

Electronic Theses and Dissertations

The burden of dental disease in American has been termed a "silent epidemic," affecting the most vulnerable populations in society. Poor oral health has been linked with general health issues, such as diabetes and cardiovascular disease, as well as decreased mental health and impairments in social functioning. This burden weighs particularly heavy on the homeless, who are not only denied access to private systems of care, but are further rejected by an inadequately supported public safety net. Despite the recognition of social inequalities and the call for further scientific research, oral health care has not been extensively recognized within sociology. …

Economic Inequality And Democratic Representative Institutions Across Western Industrialized Democracies, Donald Plungis

Electronic Theses and Dissertations

This study examines the effects of political representation on economic inequality across western industrialized democracies. I explore an explanation of increases in economic inequality as a consequence of less representative democratic institutions. Explaining economic inequality in this manner is a shift from to the Transatlantic Consensus that attributes increased economic inequality to globalization. I expect to find that more representative electoral and governments institutions will be associated with lower levels of economic inequality. The analysis takes place across twenty-three countries of the Organization for Economic Co-operation and Development (OECD) over the past forty years using a cross-sectional longitudinal model. Variables …

Effect Of Acute L-Alanyl-L-Glutamine (Sustamine) And Electrolyte Ingestion On Cognitive Function, Multiple Object Tracking And Reaction Time Following Prolonged Exercise, Gabriel Pruna

Electronic Theses and Dissertations

Changes in physiological function occurring during a body water deficit may result in significant decrements in performance, cognitive function and fine motor control during exercise. This may be due to the magnitude of the body water deficit. Rehydration strategies are important to prevent these deleterious effects in performance. The purpose of this study was to examine the changes before and after prolonged exercise of an alanine-glutamine dipeptide (AG) on cognitive function and reaction time. Twelve male endurance-trained runners (age: 23.5 [plus or minus] 3.7 y; height: 175.5 [plus or minus] 5.4 cm; weight: 70.7 [plus or minus] 7.6 kg) participated …

Distribution Of Laser Induced Heating In Multi-Component Chalcogenide Glass And Its Associated Effects, Laura Sisken

Electronic Theses and Dissertations

Chalcogenide glasses are well known to have good transparency into the infrared spectrum. These glasses though tend to have low thresholds as compared to oxide glasses for photo-induced changes and thermally-induced changes. Material modification such as photo-induced darkening, bleaching, refractive index change, densification or expansion, ablation of crystallization have been demonstrated, and are typically induced by a thermal furnace-based heat treatment, an optical source such as a laser, or a combination of photo-thermal interactions. Solely employing laser-based heating has an advantage over a furnace, since one has the potential to be able to spatially modify the materials properties with much …

Highly-Sensitive Stoichiometric Analysis Of Yag Ceramics Using Laser-Induced Breakdown Spectroscopy (Libs), Jahromi, Ali Kazemi

Electronic Theses and Dissertations

Transparent ceramics are an important class of optical materials with applications in high-strength windows, radiation detectors and high-power lasers. Despite the many successful developments of the past decades, their challenging fabrication still needs to be perfected to achieve a better consistency in optical quality. In particular, ternary phase materials such as Yttrium Aluminum Garnet (YAG, Y3Al5O12), a long standing high-power laser host, require a precise control of stoichiometry, often beyond the precision of current analytical techniques, in order to reduce scattering losses and the presence of deleterious point defects. This work explores the potential of Laser-Induced Breakdown Spectroscopy (LIBS) for …

Integral Projection Models Reveal Interactive Effects Of Biotic Factors And Disturbance On Plant Demography, Matthew Tye

Electronic Theses and Dissertations

Understanding factors limiting population growth is crucial to evaluating species persistence in changing environments. I used Integral Projection Models (IPMs) to elucidate the role of biotic interactions and disturbance on population growth rate in two plants: Helianthemum squamatum, a perennial endemic to gypsum habitats in central Spain, and Liatris ohlingerae, a long-lived perennial endemic to the Lake Wales Ridge of central Florida. In H. squamatum, there was a strong positive effect of trampling in the site with the highest plant density and moderate positive effects of seed addition in the site with the lowest plant density. Differences in treatment effectiveness …

Electronic Theses and Dissertations

The focus of this research was on the effect of school schedules on student achievement for ninth-grade students in a Florida school district. Data were collected from two central Florida high schools from the 2011-2012 and 2012-2013 school years. Five one-way analyses of covariance (ANCOVA) were performed to ascertain if there was any interaction between school schedules and student achievement. Examined were the interactions (a) between schedule and schools, (b) schedule and male students, (c) schedule and female students, (d) schedule and Black students, and (e) schedule and Hispanic students. The independent variable, school schedule, consisted of two levels: traditional …

A Professional Learning Community Design: Using Close Reading Techniques To Improve The U.S. History Comprehension, Maureen Tinsley

Electronic Theses and Dissertations

This dissertation in practice presents a research-based model for staff development utilizing the elements of a professional learning community. The focus of this problem of practice was determined through an analysis of one high school's reading data indicating that 36% of the student body was reading below grade level according to the state assessment test for reading. Researchers have noted that reading demands for college and careers have increased (Alliance for Excellent Education, 2011; Barton, 2000; Common Core State Standards, 2014). If students do not develop reading proficiency to graduate with a high school diploma, they are at risk of …

An Analysis Of The Variables In Implementation Of The Marzano Causal Teacher Evaluation System In The State Of Florida, Matthew Phillips

Electronic Theses and Dissertations

This was a non-experimental, mixed methods study to research the different ways in which the Marzano casual teacher evaluation system was implemented in 25 school districts in the state of Florida during the 2012-2013 school year. Based on seven implementation variables, the teacher evaluation systems were compared to the implementation model and research-based best practice. The researcher then sought to determine what relationships may or may not exist in teacher performance ratings between districts that followed the research-based implementation model and districts that did not. Two stated purposes of the Marzano causal teacher evaluation system were to improve the accuracy …

Closing The Reading Achievement Gap Between African American Students And Their Peers At A Suburban Middle School: The Impact Of School Improvement Plans., Jason Hutchins

Electronic Theses and Dissertations

The goal of this Dissertation in Practice was to design a School Improvement Plan focused on improving reading performance of African American students at Suburban Middle School (SMS). The problem of practice was that African American students at Suburban Middle School have performed significantly lower than their White peers over the course of the 2009-2013 school years in reading performance. The reading deficiencies of African American students needed to be directly addressed in a new School Improvement Plan (SIP). The literature review of this study found that there are many different components that influence the reading performance of African American …

(Tele)Presence In Mediated Worship: The Influence Of Antecedent Traits And The Effect On Memory, Enjoyment And Behavior, Brian Klebig

Electronic Theses and Dissertations

This study examines the phenomena of (tele)presence in the distinct mediated environment of an online Christian worship service. A quantitative field experiment involving 48 participants who had just viewed a religious Internet broadcast was undertaken. Individual differences in personality and religiosity are examined in tandem with (tele)presence as predictors of a number of outcome variables, including memory, enjoyment of the online worship service and behavioral intention to be more active with the church. The results showed no significant relationship between religiosity and the experience of (tele)presence, but that users who experienced greater (tele)presence enjoyed the service more, had a greater …

This research compared contraceptive advertisements in two top-circulated publications for white and African American female subscribers, Cosmopolitan and Essence. Data consisted of a sample of 172 contraceptive advertisements from the two magazines published between 1992 and 2012. Quantitative analysis focused on the model(s)' race, age, marital status, and socioeconomic status; the type of contraceptive being advertised; and the reason stated in the ad for using the product. This analysis determined a disparity in the rate of advertisement of doctor-administered contraceptives for the publications of 25.4 percent in Essence magazine and 9.5 percent in Cosmopolitan magazine. Black women were targeted with …

Cognitive Dissonance In The Classroom: The Effects Of Hypocrisy On Academic Dishonesty, Joanna Goldonowicz

Electronic Theses and Dissertations

Academic dishonesty and academic entitlement plague many college campuses. This research applies the theory of cognitive dissonance to the classroom in an attempt to curb academic dishonesty. Hypocrisy, a branch of the theory of cognitive dissonance, has been induced with regards to health and pro-social causes, but has not been applied to the field of higher education. In order to apply the concept of hypocrisy to academic dishonesty, a two-part experiment was conducted. The first portion of the experiment was an in-class manipulation and the second portion was an online survey conducted one month after the manipulation. Two hundred two …

In Vitro Characterization Of Unmodified And Pyroglutamylated Alzheimer's Amyloid Beta Peptide, Jason Matos

Electronic Theses and Dissertations

Plaques of amyloid β peptide (Aβ) are a hallmark trait of Alzheimer’s disease (AD). However, the precise role of Aβ aggregates is not well understood. Recent studies have identified that naturally occurring N-terminal truncation and pyroglutamylation of Aβ significantly increases its neurotoxicity by an unknown mechanism. Content of pyroglutamylated Aβ (pE-Aβ) in AD brains has been shown to reach up to 50% of total Aβ. Modified pE-Aβ co-aggregates with Aβ by a seeding mechanism and forms structurally distinct and highly toxic oligomers. We studied structural transitions of the full-length Aβ1-42, its pyroglutamylated form AβpE3-42, their 9:1 (Aβ1-42/AβpE3-42) and 1:1 molar …
