Up-Setting The Apple Cart: Mitigating Potentially Disabling Barriers In Education, Amy Tepper

Dissertations

In this study, certified general and special educators, school administrators, as well as paraprofessionals (program, classroom, and/or individual assistants), and school-based specialists (speech-language pathologists, occupational therapists, social workers, etc.) were surveyed regarding their opinions specific to the impact of potentially disabling barriers for students within the educational setting. In addition to the survey data, follow-up interviews were conducted with five select survey participants. The interview participants were selected based upon their assenting and/or dissenting opinions/responses, as well as their professional role within an educational context. The interviews were completed as a means of deriving additional, inimitable, solutions-focused insights regarding transforming …

3d Geometric Morphometrics In Modern And Extinct Foot-Propelled Diving Birds: An Evaluation Of The Tarsometatarsus For Species Identification, Mackenzie E. Kirchner-Smith

Master's Theses or Doctor of Nursing Practice

Hesperornithiformes (Aves: Ornithurae) were flightless foot-propelled diving birds that lived during the Late Cretaceous and have a good fossil record compared to most Mesozoic birds. Extinct taxa are often identified using fragmentary or isolated specimens, and several species of Hesperornis have been named from the morphology of the tarsometatarsus, often relying on size for taxonomic differentiation. However, little has been done to examine intraspecific variation in this bone and evaluate its use for taxonomic identification. To test for intraspecific and interspecific variation in the tarsometatarsus of hesperornithiforms, variation in extant members of the foot-propelled diving Gaviidae (loons) and Podicipedidae (grebes) …

Silk Road Traveler Identity Quest: Lesson Plan, Kitty Lam

History of Cultural Contact

In this lesson, students will explore intercultural contact in the Silk Road trade networks by examining the writings of Xuan Zang, a 7^th century Chinese Buddhist monk who made a pilgrimage to India to collect Buddhist texts. The text used in this exercise is Xuan Zang’s Record of the Western Regions, which was a text commissioned by the Tang Chinese Emperor. This text includes rich details of the communities Xuan Zang visited.

Perceptions Of Tornadoes, Tornado Warnings, Safety Actions, And Risk: Effects On Warning Response Among Undergraduates In Nebraska, Sabrina T. Jauernic

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Few studies show how university students perceive and respond to tornado warnings, or how they gain tornado-related knowledge. Lacking in the literature are investigations of how perceptions of tornado risk may influence actions. Using two separate surveys and two large samples of undergraduates enrolled in the University of Nebraska, the author determined significant relationships between student demographics, perceptions, and response actions. Incorrect perceptions were found, such as overpasses and southwest corners of buildings being safe, and cities being invulnerable to tornadoes. International students, especially, assumed cities were safe from tornadoes. Students had a tendency to confirm their risk instead of …

Selective Iodination Using Diaryliodonium Salts, William H. Miller Iv

Department of Chemistry: Dissertations, Theses, and Student Research

Aryl iodides have become widely recognized as versatile synthetic intermediates, owing to aromatic iodine’s excellent ability to participate in oxidative addition reactions. Iodoarenes readily undergo a variety of synthetic transformations including metal catalyzed cross-coupling reactions, diaryliodonium chemistry, formation of organometallics through reduction or metal-halogen exchange, as well as classical S_N2 type chemistry. Because a wide array of transformations are available for aryl iodides, organic molecules containing this moiety often serve as vital precursors to highly desirable pharmaceuticals.

This thesis describes a simple and selective two-step approach to the formation of aryl iodides. This method proceeds through an easily …

Abcc9/Sur2 In The Brain: Implications For Hippocampal Sclerosis Of Aging And A Potential Therapeutic Target, Peter T. Nelson, Gregory A. Jicha, Wang-Xia Wang, Eseosa T. Ighodaro, Sergey C. Artiushin, Colin G. Nichols, David W. Fardo

Sanders-Brown Center on Aging Faculty Publications

The ABCC9 gene and its polypeptide product, SUR2, are increasingly implicated in human neurologic disease, including prevalent diseases of the aged brain. SUR2 proteins are a component of the ATP-sensitive potassium (“K _ATP ”) channel, a metabolic sensor for stress and/or hypoxia that has been shown to change in aging. The K _ATP channel also helps regulate the neurovascular unit. Most brain cell types express SUR2, including neurons, astrocytes, oligodendrocytes, microglia, vascular smooth muscle, pericytes, and endothelial cells. Thus it is not surprising that ABCC9 gene variants are associated with risk for human brain diseases. For example, Cantu syndrome is …

The Effect Of Teacher-Child Interactions On Child Outcomes, Jean R. Ubbelohde

Student Work

There is a strong body of research that suggests teacher-child interactions have a positive impact on child outcomes. Quality preschool programs include a focus on intentional positive interaction between teachers and children. To support positive developmental gains in young children, early childhood settings must include responsive and cognitively stimulating daily interactions between adults and children (Hamre, 2014). Children with more responsive teachers show improved outcomes across social, behavioral and cognitive domains (Hamre, Hatfield, Pianta, & Jamil, 2014). The purpose of this correlation study was to determine the effect of teacher-child interactions on child outcomes. This focus of the study was …

Majority Rule: A Dysfunctional Polity Consensus: An Inclusive Democracy, Peter Emerson

International Dialogue

Numerous electoral systems have been devised over the years but, in decision-making, many forums still rely on the same procedure that was used in ancient Greece: majority voting. Hence, majority rule. In many plural multi-ethnic and/or multi-religious societies, the effects have often been negative. This article considers voting procedures in three inter-related contexts: decision-making, elections, and governance. With regard to conflicts in Northern Ireland, the Balkans, and Ukraine, it shows, both in decision-making and in elections, how simplistic win-or-lose ballots have exacerbated tensions. And it then suggests a more inclusive polity in which win-win voting systems might help to alleviate …

Crystal Structures Of Tris­[1-Oxo­Pyridine-2-Olato(1-)]Silicon(Iv) Chloride Chloro­Form-D1 Disolvate, Tris­[1-Oxo­Pyridine-2-Olato(1-)]Silicon(Iv) Chloride Aceto­Nitrile Unqu­Anti­Fied Solvate, And Fac-Tris­[1-Oxo­Pyridine-2-Thiol­Ato(1-)]Silicon(Iv) Chloride Chloro­Form-D1 Disolvate, Bradley M. Kraft, William W. Brennessel, Amy E. Ryan, Candace K. Benjamin

Chemistry Faculty/Staff Publications

The cations in the title salts, [Si(OPO)3]Cl·2CDCl3, (I), [Si(OPO)3]Cl·xCH3CN, (II), and fac-[Si(OPTO)3]Cl·2CDCl3, (III) (OPO = 1-oxo-2-pyridin­one, C5H4NO2, and OPTO = 1-oxo-2-pyridine­thione, C5H4NOS), have distorted octa­hedral coordination spheres. The first two structures contain the same cation and anion, but different solvents of crystallization led to different solvates and packing arrangements. In structures (I) and (III), the silicon complex cations and chloride anions are well separated, while in (II), there are two C-HCl distances that fall just within the sum of the van der Waals radii of the C and Cl atoms. The pyridine portions of the OPO ligands …

Factors Contributing To Students Seeking An Alternative Secondary School Setting, Brian Crawford

Doctor of Education (EdD)

This is a case study of six students who chose to leave a comprehensive high school that has a reputation for academic excellence. Through a triangulation of data from semi-structured private interviews with the students and their school counselors and the students’ academic records, the details of the students’ experiences at a high school exposed some of the personal factors and school-based factors that influenced their decision to leave. All of these students struggled academically, socially, or emotionally. The major thematic categories for reasons the students left that emerged from the interviews were student mobility, mental illness, socio-economic pressure, academic …

Inquiry-Based Experiments For Large-Scale Introduction To Pcr And Eestriction Enzyme Digests, Kelly E. Johanson, Terry J. Watt

Faculty and Staff Publications

Polymerase chain reaction and restriction endonuclease digest are important techniques that should be included in all Biochemistry and Molecular Biology laboratory curriculums. These techniques are frequently taught at an advanced level, requiring many hours of student and faculty time. Here we present two inquiry-based experiments that are designed for introductory laboratory courses and combine both techniques. In both approaches, students must determine the identity of an unknown DNA sequence, either a gene sequence or a primer sequence, based on a combination of PCR product size and restriction digest pattern. The experimental design is flexible, and can be adapted based on …

Lumped Parameter Model For A Self Powered Fontan Palliation Of The Hypoplastic Left Heart Syndrome, Jang Ho Park

Doctoral Dissertations and Master's Theses

Out of all newborn infants with congenital heart disease (CHD), 8% have a single functioning ventricle. The Fontan surgical procedure, where the superior and inferior venous returns are connected directly to the pulmonary arteries to allow the single functioning ventricle to perfuse the systemic circulation, has been around for decades, yet the patients who undergo this operation suffer from chronic illnesses and their survivability is less than 50% by adulthood [1-10]. Some suggest that the Fontan operation can be improved by implanting a synthetic pump. However, synthetic pumps also present some complications due to mechanical failure, risk of stroke, and …

Abundance, Stable Isotopic Composition, And Export Fluxes Of Doc, Poc, And Dic From The Lower Mississippi River During 2006-2008, Yihua Cai, Laodong Guo, Xuri Wang, George Aiken

Faculty Publications

Sources, abundance, isotopic compositions, and export fluxes of dissolved inorganic carbon (DIC), dissolved and colloidal organic carbon (DOC and COC), and particulate organic carbon (POC), and their response to hydrologic regimes were examined through monthly sampling from the Lower Mississippi River during 2006–2008. DIC was the most abundant carbon species, followed by POC and DOC. Concentration and δ¹³C of DIC decreased with increasing river discharge, while those of DOC remained fairly stable. COC comprised 61 ± 3% of the bulk DOC with similar δ¹³C abundances but higher percentages of hydrophobic organic acids than DOC, suggesting its …

The Implications Of Teacher Performance Assessment And The Impact On Teacher Decision Making, Renee Rice Moran

ETSU Faculty Works

The issue of teacher accountability has been a part of the educational conversation for three decades, but only recently has this conversation been translated into policy as states begin directly tying teacher evaluation scores in part to student achievement on standardized tests. This qualitative study focuses on a group of teachers who are participating in this new form of evaluation (containing both qualitative and quantitative elements including test scores and lesson observations) and examines how they perceived the process. In particular, the study looks at how their personal reactions to a high-stakes evaluation impacted their instructional decision making in their …

Academic Interventions And Academic Achievement In The Middle School Grades, Toby G. Kite

Dissertations

After the passing of the Individuals with Disabilities Act of 2004, many schools began to use a Response to Intervention (RtI) model instead of the discrepancy model when identifying students with specific learning disabilities (National Center on Response to Intervention, 2011). When elementary schools adopted the RtI model, it was shown to be successful with any students who need academic interventions (National Center on Response to Intervention, 2011). The success at the elementary level has led to middle schools adopting the model with varying success (National Center on Response to Intervention, 2011). In this study, middle schools that have developed …

Interactive Machine Assistance: A Case Study In Linking Corpora And Dictionaries, Kevin P. Black

Theses and Dissertations

Machine learning can provide assistance to humans in making decisions, including linguistic decisions such as determining the part of speech of a word. Supervised machine learning methods derive patterns indicative of possible labels (decisions) from annotated example data. For many problems, including most language analysis problems, acquiring annotated data requires human annotators who are trained to understand the problem and to disambiguate among multiple possible labels. Hence, the availability of experts can limit the scope and quantity of annotated data. Machine-learned pre-annotation assistance, which suggests probable labels for unannotated items, can enable expert annotators to work more quickly and thus …

Integrating Process Mining With Discrete-Event Simulation Modeling, Siyao Liu

Theses and Dissertations

Discrete-event simulation (DES) is an invaluable tool which organizations can use to help better understand, diagnose, and optimize their operational processes. Studies have shown that for the typical DES exercise, the greatest amount of time is spent on developing an accurate model of the process that is to be studied. Process mining, a similar field of study, focuses on using historical data stored in software databases to accurate recreate and analyze business processes. Utilizing process mining techniques to help rapidly develop DES models can drastically reduce the amount of time spent building simulation models, which ultimately will enable organizations to …

Alternating Direction Implicit Method With Adaptive Grids For Modeling Chemotaxis In Dictyostelium Discoideum, Christopher F. Loomis

Theses and Dissertations

Dictyostelium discoideum (Dd) is a model organism, studied for reasons from cell movement to chemotaxis to human disease control. Creating a computer model of the life cycle of Dd has garnered great interest, one part of which is the Aggregation Stage, where thousands of amoeba gather together to form a slug. Chemotaxis is the mechanism through which this is accomplished. This thesis develops two- and three-dimensional alternating direction implicit code which solves the diffusion equation on an adaptive grid. The calculated values for both two and three dimensions are checked against the actual solution and error results are provided. Comparisons …

Development And Validation Of A Physically Based Ela Model And Its Application To The Younger Dryas Event In The Graubünden Alps, Switzerland, Durban Gregg Keeler

Theses and Dissertations

The rapid rate of global warming currently underway highlights the need for a deeper understanding of abrupt climate change. The Younger Dryas is a Late-Glacial climate event of widespread and unusually rapid change whose study can help us address this need for increased understanding. Reconstructions from the glacial record offer important contributions to our understanding of the Younger Dryas due to (among other things) the direct physical response of glaciers to even minor perturbations in climate. Because the glacier equilibrium line altitude (ELA) provides a more explicit comparison of climate than properties such as glacier length or area, ELA methods …

Deriving System Vulnerabilities Using Log Analytics, Matthew Somers Higbee

Theses and Dissertations

System Administrators use many of the same tactics that are implemented by hackers to validate the security of their systems, such as port scanning and vulnerability scanning. Port scanning is slow, and can be highly inaccurate. After a scan is complete, the results of the scan must be cross checked with a vulnerability database to discover if any vulnerabilities are present. While these techniques are useful, they have severe limitations. System Administrators have full access to all of their machines. They should not have to rely exclusively on port scanning them from the outside of their machines to check for …

A Compact Phased Array Radar For Uas Sense And Avoid, Jonathan Cullinan Spencer

Theses and Dissertations

As small unmanned aerial systems (UAS) are introduced into the national airspace, measures must be introduced to ensure that they do not interfere with manned aviation and other UAS. Radar provides an attractive solution because of its inherent range accuracy and because it works in diverse weather and lighting conditions. Traditional radar systems, however, are large and high power and do not meet the size, weight and power (SWaP) constraints imposed by UAS, and fully integrated automotive solution do not provide the necessary range. This thesis proposes a compact radar system that meets both the SWaP and range requirements for …

Detecting Broken Pointcuts Using Structural Commonality And Degree Of Interest, Raffi Khatchadourian, Awais Rashd, Hidehiko Masuhara, Takuya Watanabe

Publications and Research

Pointcut fragility is a well-documented problem in Aspect-Oriented Programming; changes to the base code can lead to join points incorrectly falling in or out of the scope of pointcuts. Deciding which pointcuts have broken due to base-code changes is daunting, especially in large and complex systems. We present an automated approach that recommends pointcuts that are likely to require modification due to a certain base-code change and ones that do not. Our hypothesis is that join points selected by a pointcut exhibit common structural characteristics. Patterns describing such commonalities recommend pointcuts that have potentially broken to the developer. The approach …

The Heart Failure Overweight/Obesity Survival Paradox : The Missing Sex Link, Amanda R. Vest, Yuping Wu, Roy Hachamovitch, James B. Young, Leslie Cho

Mathematics and Statistics Faculty Publications

Objectives: This study sought to determine whether body mass index (BMI) has a differential impact on survival for females versus males with advanced systolic heart failure (HF). Background: Females have a survival advantage in HF, the mechanisms of which are unclear. There is also a proposed “obesity survival paradox” in which excess adiposity promotes HF survival. Methods: We reviewed 3,811 patients with left ventricular ejection fraction ≤40% who had undergone cardiopulmonary exercise testing between 1995 and 2011. The endpoint was all-cause mortality. Multivariable analysis was performed using a Cox proportional hazards model. Because of the nonlinearity of BMI, a restricted …
