Students Of Size: An Exploratory Case Study On A Hidden Climate, Braelin Pantel

Dissertations

Colleges and universities often espouse values related to equity and inclusion for diverse students (Harper & antonio, 2008; Torres, Arminio, & Pope, 2012;). Student affairs practitioners are frequently responsible for working towards inclusive environments (American College Personnel Association (ACPA), & National Association of Student Personnel Administrators (NASPA), 2015). An estimated 31% of college and university students are classified as overweight or obese (American College Health Association, 2007), yet body weight or size is rarely a consideration in work related to student equity and inclusion on campus. Limited research exists on the experiences of students of size in college and university …

It’S All Fun And Games Until Someone Learns To Read, Then It’S Educational: Children’S Librarians As Literacy Educators, Louise F. Benke

Dissertations

Children’s librarians who emphasize making reading and libraries fun may not think of themselves as literacy educators. But, a look into the profession’s past and three studies reveal both a history of overlap with literacy education in formal schools and informal learning and an overlap in the children’s librarians’ profession today. This dissertation presents two articles: (1) a literature review and comparative historical analysis on children’s librarians’ role in literacy instruction from 1876 to the end of the 20th century, and (2) a set of studies examining children’s librarians’ self-perceptions as literacy educators. In the first article, events in literacy …

Visual Saliency Analysis, Prediction, And Visualization: A Deep Learning Perspective, Ali Majeed Mahdi

Dissertations

In the recent years, a huge success has been accomplished in prediction of human eye fixations. Several studies employed deep learning to achieve high accuracy of prediction of human eye fixations. These studies rely on pre-trained deep learning for object classification. They exploit deep learning either as a transfer-learning problem, or the weights of the pre-trained network as the initialization to learn a saliency model. The utilization of such pre-trained neural networks is due to the relatively small datasets of human fixations available to train a deep learning model. Another relatively less prioritized problem is amount of computation of such …

Investigation Of Structural, Optical And Electronic Properties Of Modified Methylammonium Lead Iodide Perovskites, Rasanjali Jayathissa

Dissertations

Owing to their high-power conversion efficiency (PCE), easy processability, and low fabrication cost, organic lead halide perovskites (OLHP) are emerging as a most promising photovoltaic technology. However, toxicity of lead (Pb) is a major concern for further development. Therefore, it is essential to explore nontoxic metals to replace lead in these materials. In the current research work, nontoxic Mn²⁺, Na⁺ and Ba²⁺ are doped at 1, 5 and 10% mole concentrations to partially substitute Pb²⁺ in methyl ammonium lead iodide (CH₃NH₃PbI₃ or MAPbI₃) perovskite systems, and the effects …

A Cumulative Summation Nonparametric Multiple Stream Process Control Chart Based On The Extended Median Test, Austin R. Brown

Dissertations

In statistical process control applications, situations may arise in which several presumably identical processes or “streams” are desired to be simultaneously monitored. Such a monitoring scenario is commonly referred to as a “Multiple Stream Process (MSP).” Charts which have been designed to monitor an MSP typically monitor the means of the streams through collecting samples from each stream and calculating some function of the sample means. The resulting statistic is then iteratively compared to control limits to determine if a single stream or subset of streams may have shifted away from a specified target value. Traditional MSP charting techniques rely …

A Comparison Of The Effects Of Sustained Silent Reading And Reciprocal Reading On Reading Motivation For Middle School Students With Reading Delays, Margaret Uwayo

Dissertations

Research suggests that secondary students with reading delays may lack reading motivation, which can be defined as the temporal reinforcement value of texts for an individual. However, reading motivation may be a critical component of their acquisition of reading proficiency. The purpose of the current study was to compare the effects of two research-based reading interventions - sustained silent reading and modified reciprocal reading - on the reading motivation of middle school students with reading delays. Participants were four 6th-grade students who were grouped into dyads in a reading intervention classroom. The primary dependent variable was book engagement under pairing …

Predicting The Complexity Of Locality Patterns In Loop Nests In C Scientific Programs, Nasser M. Alsaedi

Dissertations

On modern computer systems, the performance of an application depends on its locality. Most existing locality measurements performed by compiler static analysis mainly target analyzing regular array references in loop nests. Measurements based on compiler static analysis have limited applicability when the loop bounds are unknown at compile time, when the control flow is dynamic, or when index arrays or pointer operations are used. In addition, compiler static analysis cannot adapt to input change.

Training-based locality analysis predicts the data reuse change across program inputs to provide run-time information. This analysis quantifies the number of unique memory locations accessed between …

Comparative Effects Of An Electronic Visual Activity Schedule On Young Children With Autism Spectrum Disorder In Increasing Independence In Activity Transitioning, Leisha Leann Tompkins

Dissertations

Young children with Autism Spectrum Disorder (ASD) often have difficulty transitioning from one activity to the next without verbal prompts from caregivers, but caregivers may not always be readily available. Binder-based visual schedules can be used to increase independence in transitioning but can be stigmatizing and cumbersome for the student. The purpose of the current study was to compare the effects of an iPadbased electronic visual to a traditional binder based visual activity schedule for elementary-aged children with ASD to increase independence activity completion and transition. Data were collected using a single-subject, alternating treatment design (A-B-CA- B-C) with three participants. …

This study examined post-graduation variables associated with the outcome on the NCLEX-RN® examination. The purpose of this exploratory field study was twofold. The first aspect was to identify the benchmark score on a post-graduation test (the Kaplan RN Readiness Exam; Sanders, 2014) correlated with passing the NCLEX-RN® examination. The second aspect was to explore factors that the …

Science Of The Art Of Coaching: Examining The Decision-Making Process Of A Competitively Successful Endurance Running Coach, Marshall James Milbrath

Dissertations

Several knowledge typologies exist as part of the coaching process including scientific, sport-specific, and pedagogical knowledges. Prior literature has examined these typologies through investigation of decision-making schematics and through direct inquiry of sport coaches. However, while past investigations have included heterogeneous coaching populations, the understanding of mediating knowledges in sport-specific contexts is less clear. Additionally, the investigation of coaching knowledges and their contributions to coach decision-making has been limited solely to the explicit and implicit viewpoints of coaches through interview studies and has yet to be investigated through observation of the coaching process itself. The present study investigated the decision-making …

The Relationship Between Student Math Achievement And Teachers Utilizing A Process Involving Interim Instructional Assessments, Douglas B. Greer

Dissertations

According to recent national and state level assessments, only about one-third of Michigan students are proficient in secondary math. Previous studies have been inconsistent in demonstrating the impact of an interim assessment process on student achievement, especially with high school mathematics. Moreover, previous studies were not found to utilize Hierarchical Linear Models (HLM) to test such a relationship, especially a three level HLM that links secondary students to a primary math teacher. Therefore, the purpose of my study was to ascertain the extent to which math teachers utilized an interim instructional assessment (IIA) process within middle and high schools, and …

Exploring Restorative Justice, Suspensions, And Expulsions With African American Males, Dorothy L. Mosby

Dissertations

Zero tolerance programs led to unequal consequences for African American males because the programs targeted behaviors African American students were more likely to receive discipline for, which resulted in an increase of disciplinary situations for the students. With the disproportionate suspensions and expulsions of African American male students in public schools, Illinois Senate Bill 100 addressed the discipline issues to reduce the number of long-term suspensions and expulsions. In the 2016–2017 school year, the state of Illinois implemented Senate Bill 100. The bill reconstructed the procedures on how school administrators suspended and expelled students; Restorative Justice was a technique used …

The Intersection Of Andragogy And Courtroom Practice, Grant Shostak

Dissertations

Learning takes place not only in a traditional classroom setting, but in a plethora of avenues outside of the lecture hall. Learning paradigms like life-long learning and Andragogy, the teaching of adults, have been used by adult educators for fields such as education, finance, accounting, law enforcement, nursing, technology, and many others. A review of the existing literature has revealed an absence of the application of andragogy to the courtroom setting. This paper investigates and discusses the andragogical orientation of successful trial lawyers in Missouri. This study has shown that successful trial lawyers have adapted and share particular principles of …

Capabilities And Limitations Of The Spin Hamiltonian Formalism In Single Molecule Magnets, Philip Ferko

Dissertations

The rational design of molecular magnetic materials is an ongoing effort involving physics, materials science, and chemistry. A common approach to design of complexes and interpretation of magnetic data is the spin Hamiltonian formalism. In this approach, magnetic data is interpreted through constants extracted from the parameterization of data. In design, certain structural motifs are pursued, rationalized by the minimization or maximization of terms in the spin Hamiltonian. In this work, monometallic complexes were prepared to simplify magnetic behavior and allow the examination of specific factors that influence single molecule magnetism like coordination geometry, ligand identity, symmetry, and spin-orbit coupling. …

Enhancing Scalability In Genetic Programming With Adaptable Constraints, Type Constraints And Automatically Defined Functions, George Gerules

Dissertations

Genetic Programming is a type of biological inspired machine learning. It is composed of a population of stochastic individuals. Those individuals can exchange portions of themselves with others in the population through the crossover operation that draws its inspiration from biology. Other biologically inspired operations include mutation and reproduction. The form an individual takes can be many things. It, however, is represented most of the time as a computer program. Constructing correct efficient programs can be notoriously difficult. Various grammar, typing, function constraint, or counting mechanisms can guide creation and evolution of those individuals. These mechanisms can reduce search space …

Decoding The History Of The Early Solar System Using Comet Volatile Compositions, Nathan Roth

Dissertations

Understanding the evolution of the solar system, as well as its current volatile content, requires knowledge of the initial conditions present in the solar nebula. As some of the first objects to accrete in the solar nebula, cometary nuclei are among the most primitive remnants of solar system formation, and their present-day volatile composition likely reflects the composition and conditions where (and when) they formed. As such, the volatile compositions of cometary nuclei may serve as "fossils" of solar system formation. High-resolution near-infrared spectroscopy offers a valuable tool for sampling the primary volatile (i.e., ices subliming directly from the nucleus) …

Gas-Phase Fragmentation Chemistry Of Small Ions, Maha Abutokaikah

Dissertations

The fragmentation chemistries of small ions are characterized in the gas-phase using mass spectrometry. I utilized experimental data and computational methods to rationalize the mechanisms of fragmentation. Density functional calculations of minima, transition states, product ions, and neutrals were performed for most of the studied systems. These systems are varied widely: Protonated peptides systems (Chapters 2 and 3), lithiated monosaccharides (Chapters 4), and protonated imine, anthracene derivatives (Chapter 5). From the experimental and theoretical data of protonated histidine-containing peptides (Chapters 2), we found that altering the position of the histidine residue had a noticeable effect on the identity of b …
