Personalized Professional Learning For Elementary Bilingual Educators: A Policy Advocacy Document, Nicole M. Robinson

Dissertations

This policy advocacy document advocates a policy to strengthen an existing elementary bilingual program through personalized professional development. Twin goals of the proposed policy are to (1) increase student achievement and (2) increase bilingual teacher retention. District 32’s bilingual program recently shifted from a Transitional Bilingual Education (TBE) model to a Developmental Bilingual Education (DBE) model, which emphasized biliteracy. As a small suburban school district with a rapidly rising Hispanic and low-income student population, this shift raised awareness among district administrators of the need for a new professional development model geared toward its mostly inexperienced bilingual teachers. To be immediately …

A high school teacher conducted a study about minority middle and high school students’ interest in science. The problem was to find out why African American and Hispanic students were showing very little interest in science. The researcher used four middle school science teachers and nine high school science teachers, all from inner city schools in a big city of the Midwest United States except for one middle school teacher from a nearby suburb. The participants answered a survey questionnaire followed with a face-to-face recorded interview. The findings of the study confirmed that students showed little interest in science due …

Blended Learning And Educational Technology: Using An Online-Digital Curriculum To Support Student Learning, Jennifer Camilleri

Dissertations

XYZ District has recently invested in a one-to-one technology initiative, providing each student in grades three through eight with an iPad. However, consistent integration of this new technology with classroom teaching strategy has been lacking, even though teachers were provided with a digital curriculum and guidance in blendedlearning pedagogy through the XYZ Internal University. This may be due, in part, to the evolving culture in many schools, as well as teacher competencies and self-efficacy in using the technology. Given the potential for significant student learning gains through the proper implementation of this technology, two representative teachers were surveyed to gather …

An Exploration Of Student Views On Grading And Learning In An Alternative School Setting, Lisa Heipp

Dissertations

Reducing barriers to learning is vital. High school teachers focus tirelessly on how best to engage students in learning; however, grading, which is a fundamental aspect of a teacher’s responsibilities, may be a significant barrier to learning. This dissertation examines students’ views on grading and learning in an alternative high school setting. The twelve students who are the focus of this research have experienced traditional school settings and an alternative charter school setting, thus they offer a perspective on grading and learning that is more widely informed than the majority of students in schools. This study is motivated by three …

Tutorial For Using The Center For High Performance Computing At The University Of Utah And An Example Using Random Forest, Stephen Barton

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Random Forests are very memory intensive machine learning algorithms and most computers would fail at building models from datasets with millions of observations. Using the Center for High Performance Computing (CHPC) at the University of Utah and an airline on-time arrival dataset with 7 million observations from the U.S. Department of Transportation Bureau of Transportation Statistics we built 316 models by adjusting the depth of the trees and randomness of each forest and compared the accuracy and time each took. Using this dataset we discovered that substantial restrictions to the size of trees, observations allowed for each tree, and variables …

On The Propagation Of Atmospheric Gravity Waves In A Non-Uniform Wind Field: Introducing A Modified Acoustic-Gravity Wave Equation, Ahmad Talaei

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Atmospheric gravity waves play fundamental roles in a broad-range of dynamical processes extending throughout the Earth’s neutral atmosphere and ionosphere. In this paper, we present a modified form for the acoustic-gravity wave equation and its dispersion relationships for a compressible and non-stationary atmosphere in hydrostatic balance. Importantly, the solutions have been achieved without the use of the well-known Boussinesq approximation which have been used extensively in previous studies.

We utilize the complete set of governing equations for a compressible atmosphere with non-uniform airflows to determine an equation for vertical velocity of possible atmospheric waves. This intricate wave equation is simplified …

Tests Of Lorentz Symmetry In The Gravitational Sector, Aurélien Hees, Quentin G. Bailey, Adrien Bourgoin, Hélène Pihan-Le Bars, Christine Guerlin, Christophe Le Poncin-Lafitte

Publications

Lorentz symmetry is one of the pillars of both General Relativity and the Standard Model of particle physics. Motivated by ideas about quantum gravity, unification theories and violations of CPT symmetry, a significant effort has been put the last decades into testing Lorentz symmetry. This review focuses on Lorentz symmetry tests performed in the gravitational sector. We briefly review the basics of the pure gravitational sector of the Standard-Model Extension (SME) framework, a formalism developed in order to systematically parametrize hypothetical violations of the Lorentz invariance. Furthermore, we discuss the latest constraints obtained within this formalism including analyses of the …

Design Of A Rotating Brush Underwater Grooming Device With A Focus On Brush Optimization, Motor Control And Design For Reliability, Mark Harrison Nanney

Theses and Dissertations

The design and control of Remotely Operated Vehicles (ROV) to groom or clean the underwater surface of ship hulls is becoming an important aspect of the maintenance of vessels to the United States Navy. The biological growth below the waterline of the vessels can be the cause for drag penalties near 21% causing up to 32% increase in shaft power at 15 knots (Schultz, 2007). Research conducted by the Center for Corrosion and Biofouling Control at Florida Institute of Technology (FIT) indicated that weekly grooming can prevent high profile biological growth (Hearin, et al., 2015). The design of a rotating …

Soteria: A Persuasive Esecurity Assistant, Punica Bhardwaj

Theses and Dissertations

“…security is only as good as the weakest link, and people are the weakest link in the chain.” – B Schneier, 2002 Humans are often referred to as the “weakest link” in the security chain because of the poor security decisions taken by them. There can be many reasons for these decisions, such as lack of understandability of the software, lack of education, and lack of relevant information required to do that particular action. In this Thesis, we focus on the lack of relevant information required at the time of performing the action. In order to provide the user with …

Dual Role Of Sb Ions As Electron Traps And Hole Traps In Photorefractive Sn2P2S6 Crystals, Brant E. Kananen, Eric M. Golden, Sergey A. Basun, D. R. Evans, A. A. Grabar, I. M. Stoika, John W. Mcclory, Nancy C. Giles, Larry E. Halliburton

Faculty Publications

Doping photorefractive single crystals of Sn₂P₂S₆ with antimony introduces both electron and hole traps. In as-grown crystals, Sb³⁺ (5s²) ions replace Sn²⁺ ions. These Sb³⁺ ions are either isolated (with no nearby perturbing defects) or they have a charge-compensating Sn²⁺ vacancy at a nearest-neighbor Sn site. When illuminated with 633 nm laser light, isolated Sb³⁺ ions trap electrons and become Sb²⁺ (5s²5p¹) ions. In contrast, Sb³⁺ ions with an adjacent Sn vacancy trap holes during illumination. The hole is primarily …

A System For Detecting Malicious Insider Data Theft In Iaas Cloud Environments, Jason Nikolai, Yong Wang

Research & Publications

The Cloud Security Alliance lists data theft and insider attacks as critical threats to cloud security. Our work puts forth an approach using a train, monitor, detect pattern which leverages a stateful rule based k-nearest neighbors anomaly detection technique and system state data to detect inside attacker data theft on Infrastructure as a Service (IaaS) nodes. We posit, instantiate, and demonstrate our approach using the Eucalyptus cloud computing infrastructure where we observe a 100 percent detection rate for abnormal login events and data copies to outside systems.

Sedimentology Of A Small Estuarine Marsh Along East (Pensacola) Bay, Florida, Jesse Pfadenhauer

Honors Theses

Sediment samples from a marsh along East (Pensacola) Bay were analyzed using various laboratory techniques. The color, magnetic susceptibility, organic content, carbonate content, and sediment size distribution of each sample was measured to attain an overall profile of the sedimentary characteristics of the area. Using the GPS coordinates of each collection site, samples were categorized into sub-environments based on their position within the marsh. The trends within the study area and sub-environments were evaluated and interpreted. The data indicate that this marsh is a siliciclastic, fining-inland area that is frequently inundated with tidal fluctuations and storm surges. These storm surges …

High Order Harmonic Generation From Sf₆: Deconvolution Of Macroscopic Effects, B. P. Wilson, K. D. Fulfer, S. Mondal, X. Ren, J. Tross, E. D. Poliakoff, J. Jose, Anh-Thu Le, R. R. Lucchese, Carlos A. Trallero-Herrero

Physics Faculty Research & Creative Works

We measure high order harmonics from the molecule SF₆ over a large range of phase matching conditions and observe several features in the harmonics that are largely independent of such macroscopic conditions. The experimental data are then compared to the quantitative rescattering theory for the generation of harmonics from three orbitals. With this comparison, we are able to assign spectroscopic features in the harmonics to contributions from 1t_1g (HOMO) and 5t_1u (HOMO-1) orbitals.

Analysis Of Professors’ Perceptions Towards Institutional Redevelopment Of Brownfield Sites In Alabama, Berkley Nathaniel King Jr.

Dissertations

This study was conducted to analyze professors’ perceptions on the institutional redevelopment of brownfield sites into usable greenspaces. The U.S. Environmental Protection Agency (2011) refers to brownfields as sites, (either facility/land) under public law § 107-118 (H.R. 2869), which are contaminated with a substance that is classified as a hazard or a pollutant. Usable greenspaces, however, are open spaces or any open piece of land that is undeveloped, has no buildings or other built structures, and is accessible to the public (EPA, 2015).

Open green spaces provide recreational areas for residents and help to enhance the beauty and environmental quality …
