CO-TEACHING PRACTICES OF GENERAL AND SPECIAL EDUCATORS IN SECONDARY SCIENCE CLASSROOMS

Samantha Ringl
The purpose of this study was to establish current levels of co-teaching implementation and to explore teachers’ perceptions of co-teaching and co-teacher relationships. This study also examined whether there is a relationship between teachers’ perception of their co-teaching relationship and their perception of co-teaching implementation in their classrooms. Analysis revealed that teachers generally have positive perceptions of their co-teaching partners and relationships, and these perceptions did not significantly differ between science teachers and special educators....

Novel Nonparametric Testing Approaches for Multivariate Growth Curve Data

Ting Zeng
Multivariate growth curve data naturally arise in various fields, for example, biomedical science, public health, agriculture, social science and so on. For data of this type, the classical approach is to conduct multivariate analysis of variance (MANOVA) based on Wilks' Lambda and other multivariate statistics, which require the assumptions of multivariate normality and homogeneity of within-cell covariance matrices. However, data being analyzed nowadays show marked departure from multivariate normal distribution and homoscedasticity. In this dissertation,...

Synthesis, Crystal Engineering, and Material Properties of Small-Molecule Organic Semiconductors

Emma Holland
Small-molecule organic materials are of increasing interest for electronic and photonic devices due to their solution processability and tunability, allowing devices to be fabricated at low temperature on flexible substrates and offering utility in specialized applications. This tunability is the result of functionalization through careful synthetic strategy to influence both material properties and solid-state arrangement, both crucial variables in device applications. Functionalization of a core molecule with various substituents allows the fine-tuning of optical and...

Innovative Statistical Models in Cancer Immunotherapy Trial Design

Jing Wei
A challenge arising in cancer immunotherapy trial design is the presence of non-proportional hazards (NPH) patterns in survival curves. We considered three different NPH patterns caused by delayed treatment effect, cure rate and responder rate of treatment group in this dissertation. These three NPH patterns would violate the proportional hazard model assumption and ignoring any of them in an immunotherapy trial design will result in substantial loss of statistical power. In this dissertation, four models...

THE ROLE OF ALEXITHYMIA AND AFFECTIVE LABILITY IN DISORDERED EATING BEHAVIORS

Anna Marie Ortiz
Affective distress may influence eating disorder behaviors in multiple ways. Affective lability refers to the tendency to experience frequent and striking fluctuations in mood. There is considerable evidence that it predicts eating disorder symptoms. Further, alexithymia is characterized by difficulties identifying and describing feelings and an externally oriented thinking style. Alexithymia has also been implicated in the development and maintenance of eating disorders. To date, these risk factors have been studied separately. Given the evidence...

Teen dating violence, including sexual violence (unwanted sexual contacts or activities), physical and psychological dating violence, sexual harassment, and stalking, affects high school students' physical and mental health and academic achievement in the United States. Dating violence is linked to psychological abuse perpetration in the future, depression, anxiety, and hostility. The teen dating violence victimization experience was related to antisocial behavior, drug...

UNDERSTANDING THE ROLE OF CHARGE ON PARTICLE TRANSPORT WITHIN SEMIDILUTE AND CONCENTRATED BIOPOLYMER SOLUTIONS AND TAU PROTEIN CONDENSATES

Kanthi Nuti
Biological polymer networks such as mucus, extracellular matrix, nuclear pore complex, and bacterial biofilms, play a critical role in governing the transport of nutrients, biomolecules and particles within cells and tissues. The interactions between particle and polymer chains are responsible for effective selective filtering of particles within these macromolecular networks. This selective filtering is not dictated by steric alone but must use additional interactions such electrostatics, hydrophobic and hydrodynamic effects to control particle transport within...

Plant roots are often overlooked when making nutrient management decisions. Evaluating differences in P acquisition strategies and cycling resulting from years of shoot-specific plant breeding will aid in reducing fertilizer inputs, with the ultimate goal of improving economic sustainability of crop production and preservation of ecosystem services. To achieve this goal, this research screened a diverse panel of winter wheat cultivars that included old and modern, dwarfed and wild type varieties for physical and chemical...

A TEST OF THE “TEACHABLE MOMENT” HEURISTIC’S RELEVANCE FOR UNDERSTANDING CANCER SURVIVORS’ HEALTH BEHAVIOR MOTIVATION AND PERFORMANCE

Gabriella Puleo
Cancer diagnosis has potential to motivate health behavior changes to promote better health outcomes. The Teachable Moment Heuristic is a parsimonious, transtheoretical framework for understanding the conditions under which behavior change might occur, with constructs that include affective, cognitive, and social factors. This exploratory study aimed to measure the three primary constructs of the Teachable Moment, evaluate the extent to which they are associated with cancer survivors’ motivation to adopt favorable health behaviors, and explore...

THE ACUTE EFFECT OF HIGH INTENSITY RESISTANCE TRAINING ON SUBSEQUENT FIREFIGHTER PERFORMANCE

Mark Mason
High intensity resistance training (HIRT) is commonly performed by structural firefighters to enhance preparedness for occupational demands. Despite the potential for HIRT to induce beneficial adaptations over time, it is important to determine if a single on-duty HIRT session is detrimental to subsequent occupational physical ability due to exercise-induced fatigue. Therefore, the primary purpose of this study was to assess the acute effect of HIRT on occupational physical ability in structural firefighters and to determine...

THREE ESSAYS ON THE HIGH-SPEED RAIL NETWORK IN CHINA

Shiyu Cheng
My dissertation consists of three essays that study the economic consequences of China’s high-speed rail (HSR) expansion. In the first essay, I use the college admission cutoff scores to reveal students’ college preferences under the enrollment quota. By exploiting the quasi-experimental variation in whether or not college cities are connected by the HSR network, I document a two-point increase in the cutoff scores following a HSR station opening in the college city using difference-in-difference (DD)...

IDENTIFICATION AND CHARACTERIZATION OF EPITOPE SPECIFIC IMMUNE RESPONSES IN HUMANS AND MICE

David Henson
Cardiovascular disease (CVD) is a major cause of morbidity and mortality around the world causing approximately 14% of total disease burden. A major factor in the progression to major CVD within patients is immune activation, which led to the study of various immune products as potential biomarkers for the prediction of cardiovascular events, including antigen-specific antibodies and immune complexes. One focus of this biomarker research is IgG autoantibodies targeting apolipoprotein A-I (ApoA-I), and several studies...

WHAT YOU DO OR WHAT YOU SAY? AN EXAMINATION OF ANALYST REACTIONS TO PROTOTYPICAL AND NON-PROTOTYPICAL CEOS LINGUISTIC AND COMPETITIVE BEHAVIORS

Courtney Hart
Non-prototypical CEOs are those that process different demographic characteristics from a target reference group. In the US, a non-prototypical CEO is both white and male. While the negative responses to non-prototypical leaders based on race and gender have been well documented, we know less on what these leaders do that may influence biased evaluations. In this dissertation I took an impression management view to examine analysts’ evaluative bias (AEB) on prototypical and non-prototypical CEOs hiding...

POLITICAL ECONOMY OF THE PRODUCTION OF HERITAGE SPACE IN A CENTRO HISTÓRICO

Camilo Rey-Sabogal
Cartagena is a South American city whose historical built environment has been recognized as a World Heritage Site due to the preservation of elements of the Spanish military architecture of the 16th, 17th and 18th centuries. This recognition promoted a tourist and real estate boom in the Centro Histórico and, as a result, its inhabitants have faced gentrification dynamics that are expelling them to other areas of the city. During the last 15 years, these...

Flavin Modification and Redox Tuning in the Bifurcating Electron Transfer Flavoprotein from Rhodopseudomonas palustris

Nishya Mohamed Raseek
Electron bifurcation is considered as a third fundamental mode of energy conservation mechanism in addition to two well-known mechanisms, substrate level phosphorylation and Oxidative phosphorylation, in electron bifurcation endergonic and exergonic redox reactions are coupled. The newly discovered flavin based electron bifurcation in electron transfer flavoproteins (ETFs) helps to reduce low potential ferredoxin, which provides electrons to drive biologically demanding reactions such as atmospheric dinitrogen fixation in diazotroph and methane production in methanogens. Current research...

Patient satisfaction and quality of life are integral parts of assessing the quality of oral health care. Current aging population trends suggest a growing need to understand the effects of edentulism on oral health and quality of life. As the proportion of aged Americans expands, there will be an increased need to understand treatment options and patient communication strategies. In addition, as new treatment options and innovative technologies emerge, it will be essential to understand...

IMPACT OF PTSD ON HCV/HIV RISK-REDUCTION INTERVENTIONS AMONG INCARCERATED DRUG-USING WOMEN IN RURAL APPALACHIA

Caitlyn O. Hood
Justice-involved women in rural Appalachian Kentucky are a particularly vulnerable group in need of targeted risk-reduction interventions for hepatitis C virus (HCV) and human immunodeficiency virus (HIV). Compared to women in the general U.S. population, justice-involved women in rural Appalachia report dramatically higher rates of HCV/HIV risk behaviors (e.g., injection drug use and risky sex), interpersonal violence (IV; e.g., physical, sexual, or emotional abuse), and posttraumatic stress disorder (PTSD). IV and PTSD may exacerbate rural...

\"IT'S NOT RAINBOWS AND UNICORNS\"

Hugh Deaner
This dissertation examines the regulated oilsands mining industry of Alberta, Canada, widely considered the world’s largest surface mining project. The industrial processes of oilsands mining produce well over one million barrels of petroleum commodities daily, plus even larger quantities of airborne and semisolid waste. The project argues for a critical account of production concretized in the co-constitutional relations of obdurate materiality and labor activity within a framework of regulated petro-capitalism. This pursuit requires multiple methods...

A Decoupled Engineering Methodology for Accurate Prediction of Ablative Surface Boundary Conditions in Thermal Protection Systems

Justin Cooper
The main objective of the present work is to demonstrate a method for prediction of aerothermal environments in the engineering design of hypersonic vehicles as an alternative to the current heritage method. Flat plate and stagnation point boundary layer theory require multiple assumptions to establish the current engineering paradigm. Chief among these assumptions is the similarity between mass and heat transfer. Origins of these assumptions are demonstrated and their relationship to conservative engineering design is...

REGULATORY MECHANISMS IN ARABIDOPSIS EMBRYOGENESIS

Sanjay Joshi
Plants have amazing regeneration properties with single somatic cells, or groups of cells able to give rise to fully formed plants. One means of regeneration is Somatic Embryogenesis (SE), by which an embryonic structure is formed that “converts” into a plantlet. Somatic embryogenesis has been used as a model for zygotic processes that are buried within layers of maternal tissues. Understanding mechanisms of somatic embryo induction and development are important as a more accessible model...

TRANSFORMATIVE LEARNING THROUGH ORAL NARRATIVE IN A PARTICIPATORY COMMUNICATION CONTEXT

Charles Madinger
This research investigates instructional narrative interventions for transformative learning among high orality reliant peoples. Two research questions asked: “Does an oral strategy of radio drama in a participatory environment lead to significant changes in knowledge and beliefs,” with a hypothesis stating there would be significant positive changes; and “When listeners experience narrative transport can it affect receptivity leading to knowledge and belief change,” and the hypothesis stated that narrative transport would correlate to higher positive...

THE (MILLENNIAL) TIMES, THEY ARE A’CHANGIN’

Hayley Hoffman
Drawing from over a decade of research, it can be said with relative certainty what millennial learners expected of their instructors when they were in the college classroom. But what about the expectations and needs of our current group of students, Generation Z? Because few studies exist on Gen Z in higher education spaces, this dissertation establishes a baseline of what these students might need and expect from market and generational research on this group...

PHOTOCATALYTIC APPLICATIONS OF TiO2 FOR CATECHOL DEGRADATION AND α-Fe2O3 FOR CARBON DIOXIDE REDUCTION AT AIR-SOLID INTERFACE

Md. Ariful Hoque
Natural and anthropogenic processes are emitting organic and inorganic pollutants, such as phenolic compounds, carbon dioxide (CO2), etc. in the atmosphere, which are increasing with time. In addition, to meet the energy demand of world’s growing population using nonrenewable fossil fuels are causing its depletion. Therefore, development of new technologies that can minimize atmospheric pollution and contribute to energy demand is imperative. Many methods or technologies have been developed for addressing those issues so far...

The Role of Sexual Difference in Plato's Timaeus

Mary Cunningham
My dissertation is a reading of Plato’s Timaeus that centers sexual difference and in particular femininity. I analyze the role of sexual difference in the framing of the dialogue as well as its accounts of body in the first and second discourse and its account of health in the third discourse. I argue that sexual difference, and, in particular, sexual reproduction, serves as a guiding paradigm of Timaeus’ entire project. I argue in each part...
