Early Career Special Education Teachers Perceived Value Of Being Mentored By General Education Teachers, Kyena E. Cornelius Ed.D., Karin N. Sandmel Ph.D.

The Journal of Special Education Apprenticeship

Special education induction research has examined mentor support and working conditions of early career special education teachers (ECSETs) for over 20 years. Recently researchers provide specialized professional development to mentors based on suggestions of special education induction research. Drawing on quality indicators of single-subject research and the belief that social validity data is valuable, we used qualitative methods to discover ECSETs’ perceptions of the intervention and the helpfulness of the mentors. We then compared responses of the participants with the existing research in special education induction. Findings indicate the participants appreciated the specialized training for their mentors and perceived their …

Impacts Of Habitat Attributes And Community Gardens On Urban Bird Communities, Samuel Glenn Ortiz

Theses and Dissertations

The Rio Grande Valley of Southern Texas is a major agricultural region yet has some of the highest hunger rates in the USA. Urbanization and agriculture affect biodiversity, which is well studied, but little is known about how agriculture affects biodiversity in urban areas. We investigated how different urban attributes, including those related to urban farming, impact bird communities in Brownsville and Harlingen, TX, and compared sites that have community gardens to those that do not. To study three key urban habitat characteristics, we identified sites that exhibited all possible combinations of these factors, quantified land cover classes related to …

Longitudinal And Temporal Comparison Of Beach Sand On The Rio Grande Delta System, Samantha B. Moore

Theses and Dissertations

The Rio Grande is the 5th longest river in North America and defines a significant extent of the United States-Mexico border. It extends for 2830 km from its headwaters in the Rocky Mountains of Colorado to the Gulf of Mexico. The Rio Grande is fed by streams from the Sangre de Cristo Mountains, the Rio Conchos, the Pecos River, runoff from the Sacramento Mountains area, Devils River, the Rio Salado, and the Rio San Juan. This study addresses how the composition of sand forming the Rio Grande river delta into the Gulf of Mexico at Boca Chica Beach is changed …

Imidacloprid Persistence, Mobility, And Effect On Ecosystem Function, Joanna Hardin

Electronic Theses and Dissertations

Imidacloprid is a neonicotinoid pesticide used to protect against biting and sucking insects. Land managers rely on its systemic properties, however long-term studies investigating imidacloprid effects on ecosystem function are limited. This study investigated imidacloprid applications to Tsuga caroliniana and Tsuga canadensis over time and compared concentrations to measures of ecosystem function including soil respiration, microbial function, and invertebrate density. Results indicate that imidacloprid is persistent (p0.5). Microbial function and invertebrate density were not significantly different between control and treatment locations nor did imidacloprid concentrations correlate with ecosystem functional indicator activity (p>0.05). It is evident that imidacloprid does not …

Aligning Anatomical Knee Model With Kinematic Experimental Data To Investigate Squat Exercise, Jose Mario Salinas

Theses and Dissertations

A two-dimensional inverse dynamics anatomical model of the human knee was developed by aligning anatomical structures of the knee (taken from x-rays) with kinematic experimental data (collected from motion capture cameras). The mathematical model was used to study the forces related to the tibiofemoral and patellofemoral joints during the squat and knee extension exercises. Forces calculated by the model included: tibiofemoral contact force, patellofemoral contact force, forces generated by cruciate ligaments, quadriceps force, and patellar tendon force. Bone alignment consisted of superimposing the geometric center of the lateral femoral condyle (from x-rays) with the relative instantaneous center of rotation of …

Radiative Heat Transfer Analysis Of Railroad Bearings For Wayside Thermal Detector Optimization, James Alexandro Aranda

Theses and Dissertations

Wayside hot-box detectors (HBDs) are devices that are currently used to evaluate the health of railcar components including bearings, axles, and brakes by monitoring their temperatures. While HBDs have been instrumental in reducing some train derailments in the past few decades, the number of non-verified bearing removals has increased significantly. In general, HBDs tend to underestimate bearing temperatures in both field service and in laboratory testing, which is not surprising considering the simple two-point calibration method that is used to calibrate these devices. Because of this, different calibrations were compared and analyzed including two-point, three-point, and multi-point calibrations. Analysis of …

The freshmen cohort 2015 in one south Texas urban school district in the Rio Grande Valley was the focus of the study. Exploratory and confirmatory analysis statistical/data …

Investigating Faculty Across The Disciplines Perceptions And Practices Of Reflective Writing In Community Engaged Courses: A Comparative Study, Marcela Hebbard

Theses and Dissertations

Recently, research in composition studies and Writing Across the Curriculum (WAC) has focused on understanding better how student reflective practices assist on their transfer of writing knowledge across contexts (Yancey et al., 2014; Taczak & Robertson, 2017, Lindenman et al., 2018). However, not much research has been done that investigates faculty beliefs and practices about reflective writing, how they use it to measure student outcomes and achievement in community engaged courses and the implications this might have for the transfer of knowledge and practice of writing. This study draws primarily on activity theory to better understand whether there is a …

Three Dimensional Carbon Nanotube Yarn Based Perovskite Solar Cells, Istiak Hussain

Theses and Dissertations

Perovskite solar cells (PSC) have emerged as a promising photovoltaic technology in lab scale with a short time of research due to their high power conversion efficiency, simple device fabrication, all solid-state structure and the possibility to ingrate the traditional device into fiber format. In this work, a three-dimensional (3D) perovskite solar cell is demonstrated using functionalized carbon nanotube yarn (CNT) as both cathode and anode. TiO2 and 2,2,7,-7-tetrakis(N,N-di-p-methoxyphenylamine)-9,9'-spirobifluorene (Spiro-OMeTAD) are used as the electron transporting and hole transporting material respectively. The TiO2 oxide layer is deposited on the top of the twisted carbon nanotube yarn and annealed with TiCl4 …

Identities For Partitions Of N With Parts From A Finite Set, Acadia Larsen

Theses and Dissertations

We show for a prime power number of parts m that the first differences of partitions into at most m parts can be expressed as a non-negative linear combination of partitions into at most m – 1 parts. To show this relationship, we combine a quasipolynomial construction of p(n,m) with a new partition identity for a finite number of parts. We prove these results by providing combinatorial interpretations of the quasipolynomial of p(n,m) and the new partition identity. We extend these results by establishing conditions for when partitions of n with parts coming from …

Blow-Up Solutions Of Wave Map Equations With Periodic In Time Speed Of Propagation, Nathalie M. Luna-Rivera

Theses and Dissertations

We study the initial value problem for the wave map equation with time-dependent speed of propagation. In particular, for arbitrary, small, and smooth initial data we construct blow-up solutions of the wave map with coefficients that are periodic in time. For the proof we use Lyapunov-Floquet theory and Borg’s theorem.

Asymptotic Quantization For A Condensation System Associated With A Discrete Distribution, Shankar Parajulee

Theses and Dissertations

Let P := (1/3)P ○ S1–1 + (1/3)P ○ S2–1 + (1/3)v be a condensation measure on R, where S1(x) = (1/5)x, S2(x) = (1/5)x + 4/5 for all x ∈ R , and v is a discrete distribution on R with the support of v equals C := {(2/5), (3/5)}. For such a measure P we determine the optimal sets of n–means and the nth quantization errors for all n ≥ 2. In addition, we show that the quantization dimension of the condensation measure P exists and equals …

Effects On Altering Reaction Conditions In Suzuki Cross Coupling Reactions Using The Microwave, Javier Alejandro Perez

Theses and Dissertations

Over the last few decades, Suzuki coupling has become a common process for the synthesis of intermediates in pharmaceutical and industrial applications. It is well known that palladium is an effective catalyst for the formation of cross-coupled products. Therefore, this catalyst was tested in a series of reactions. Also, it is believed that other catalyst with similar properties to palladium can work, for example cerium. Therefore, a cerium hydroxide catalyst was synthesized in lab and used as a potential catalyst for the Suzuki reaction. For this study, some bases were investigated (NaOH, Na2CO 3, K3PO4, NaNO3, NaHCO3, etc) for the …

Effect Of Humidity And Testing Strategy On Friction Performance Of Model Brake Pads Containing Nano-Additives, Saikrishna Kancharla

Theses

Interaction of brakes with external environment can considerably influence their performance which could relate to friction instabilities. Humidity can alter the chemistry of friction surfaces that could relate to unwanted phenomena which increase the cost of product. In addition to the chemical phenomena leading to unwanted reactions, there are physical effects related to adsorption of humidity and to modification of adhesion, accompanied with changes in contact surfaces and contact mechanics. The goal of this paper is to address these chemical and physical phenomena occurring at friction interfaces of model friction materials and to relate them to their performance. Friction tests …

Endocytosis As An Additional Mechanism Of Glucose Transport To The Hexose Transporter In Trypanosoma Brucei, Jongsu Choi

Theses and Dissertations

Trypanosoma brucei is an extracellular kineotoplastid parasite that causes human African trypanosomiasis (HAT), also known as sleeping sickness. As trypanosomes undergo vector to host transition, heavy transcriptional adaptation such as metabolic shift to glycolysis and upregulated endocytosis occurs. Specifically, glycolysis in the infectious stage becomes the sole source of energy production; thus, the glucose transport mechanism in T. brucei provides one of the most promising therapeutic targets for development of new drugs to treat HAT. Despite an established trypanosome hexose transporter (THT) model for glucose transport across the plasma membrane, there remains gaps in the detailed mechanism of glucose transport …

Combining Faithfulness With Learning: Avoiding The Path Of Secularization At Brigham Young University, J. Gordon Daines Iii

Theses and Dissertations

Most research universities in the United States began as religiously affiliated institutions. Beginning in the late 19th century and continuing over the course of the 20th century, the vast majority of these institutions engaged in a process of secularization through which faith moved from the center of academic life to the periphery. This paper elucidates a conceptual framework for understanding how and why Brigham Young University did not follow the path of secularization that so many research universities, originally religious in nature, pursued. It examines the steps that the university and its sponsoring institution (The Church of Jesus Christ of …

Using Non-Destructive Testing To Predict Bending Modulus Of Carbon Infiltrated-Carbon Nanotubes, Fred Stile Fagergren

Theses and Dissertations

Fabrication of carbon infiltrated carbon nanotubes (CI-CNT) can result in large mechanical property variation, and methods to characterize properties usually involve destructive testing. Finding a non-destructive way to test for stiffness of this material reduces the number of parts that have to be made. It also simplifies testing of complex parts. The stiffness of CI-CNT beams is related to the type of carbon material infiltrated between the carbon nanotubes (CNTs), how it interacts with the CNTs, and how much of it there is. The amount of material can be estimated using the density of the beam, and both the type …

Normally Supportive Sublattices Of Crystallographic Space Groups, Miles A. Clemens

Theses and Dissertations

Normal subgroups can be thought of as the primary building blocks for decomposing mathematicalgroups into quotient groups. The properties of the resulting quotient groups are oftenused to determine properties of the group itself. This thesis considers normal subgroups of threedimensionalcrystallographic space groups that are themselves three-dimensional crystallographicspace groups; for convenience, we refer to such a subgroup as a csg-normal subgroup. We identifypractical restrictions on csg-normal subgroups that facilitate their tabulation. First, the point groupof an csg-normal subgroup must be a normal subgroup of the crystallographic point group of thespace group, which we refer to for convenience as a cpg-normal subgroup. …

Racing To Regulation: A Comparative Analysis Of Virtual Currency Regulation In Alaska And The Proposed Alaska Money Services Act Carlos Manzano, Carlos Manzano

Alaska Law Review

The emergence of virtual currencies has revolutionized the financial industry by creating an alternative form of payment that seeks to insulate individuals from government and bank influence. Yet, federal regulation of virtual currency has remained limited. Many state legislators have rushed to fill the gap by enacting laws regulating virtual currency use and transmission. This state-by-state approach has led to significant variation between state regulatory regimes, creating a regulatory spectrum of lenient to strict regulatory approaches. In March 2017, Alaska House Representatives Zach Fansler and Sam Kito proposed the Alaska Money Services Act to require licensing for virtual currency activity. …

The Effects Of Within-School Consultation On General Education Teachers’ Use Of Behavior-Specific Praise With Students With Emotional Disabilities, Darrelanne M. Sundeen

Dissertations

Students identified with emotional disabilities (ED) are increasingly being included in the general education academic classrooms. Most general education academic teachers have little training or exposure to the characteristics and interventions associated with students with ED. Behavior-specific praise (BSP) has been shown to be an effective intervention for decreasing problem behaviors in the classroom. Unfortunately, studies have shown that teachers generally provide low rates of praise to secondary students and less so to secondary students with ED. This study used a multiple baseline single-subject design across participants to assess whether the use of within-school consultation intervention which involved regular structured …

Investigating Employability: Testing The Raw Framework, Daniell Jean Study

Electronic Theses, Projects, and Dissertations

In a recent model of employability, Hogan, Chamorro-Premuzic, and Kaiser (2013) defined employability as the ability to gain and maintain employment and find new employment when necessary. The authors presented employability as a formative construct containing an ability dimension (the ability to do the job), a social skills dimension (being rewarding to work with), and a motivational dimension (being willing to work hard). There is no question as to whether these three dimensions affect one’s level of employability; research is abundant on the positive relationships between intelligence, social and emotional skills, motivation and career success. However, little research has been …

The Right To Be Human: Universal Design For Learning And Literacy Sponsorship As Liberatory Pedagogy, Jeremy Lunasco

Electronic Theses, Projects, and Dissertations

This project explores the possibilities of implementing a critical and liberatory pedagogy within the confines of the prison. Building upon the fields of critical prison theory, literacy studies, and (dis)ability studies, I assert that implementing small, organic, and tactical changes though the principles of Universal Design for Learning allows the prison educator to make impactful moves with liberatory goals. I conclude by reimagining what a prison education mission statement that takes this perspective looks like then imagine the liberatory applications of the principles of universal design for learning within the prison.

Recognizing human activities using deep learning methods has significance in many fields such as sports, motion tracking, surveillance, healthcare and robotics. Inertial sensors comprising of accelerometers and gyroscopes are commonly used for sensor based HAR. In this study, a Bidirectional Long Short-Term Memory (BLSTM) approach is explored for human activity recognition and classification for closely related activities on a body worn inertial sensor data that is provided by the UTD-MHAD dataset. The BLSTM model of this study could achieve an overall accuracy of 98.05% for 15 different activities and 90.87% for 27 different activities performed by 8 persons with 4 …

Exploring Flag Matroids And Duality, Zachary Garcia

Electronic Theses, Projects, and Dissertations

Matroids capture an abstraction of independence in mathematics, and in doing so, connect discrete mathematical structures that arise in a variety of contexts. A matroid can be defined in several cryptomorphic ways depending on which perspective of a matroid is most applicable to the given context. Among the many important concepts in matroid theory, the concept of matroid duality provides a powerful tool when addressing difficult problems. The usefulness of matroid duality stems from the fact that the dual of a matroid is itself a matroid. In this thesis, we explore a matroid-like object called a flag matroid. In particular, …

Seismicity In Nebraska And Adjacent States: The Historical Perspective And Current Trends, Irina Filina, Kris Guthrie, Mindi Searls, Caroline M. Burberry

Department of Earth and Atmospheric Sciences: Faculty Publications

A sudden spike in earthquake events has been observed in central Nebraska. Since April 2018, 26 earthquakes with equivalent moment magnitudes from 2.7 to 4.1 occurred, clustered tightly in Custer County. A similar cluster of 24 earthquakes with equivalent moment magnitudes from 2.6 to 3.7 occurred in Jewell County in northern Kansas in 2017. We have compiled an earthquake database for Nebraska and parts of adjacent states from different sources to determine whether these recent earthquake spikes are consistent with historic seismicity. We identified two historic earthquake clusters occurring in our study area. The first contained 32 events and was …

Hydrogeologic Framework Studies Of Portions Of The Niobrara River, Douglas R. Hallum, Steven S. Sibray, Leslie M. Howard

Conservation and Survey Division: Faculty and Staff Publications

The Nebraska Department of Natural Resources (NeDNR) and Upper Niobrara-White Natural Resources District (UNWNRD) expressed interest in improving understanding and their ability to effectively manage water resources in and around a particular reach of the Niobrara River. Aquifer-thickness contours mapped by the Conservation and Survey Division (CSD) indicate that the principle aquifer has zero thickness in this area. Additionally, the statewide geologic bedrock map produced by CSD shows non-aquifer strata of the White River Group along the same reach, and this setting is consistent with the designation of an “aquifer absent area,” as in the present document. Water-management policy development …

School water, sanitation and hygiene (WASH) facilities were also assessed. Univariate weighted population prevalence was estimated and multivariable logit regression analyses applied to explore associations.

Results: A total of …

Feature-Based Transfer Learning In Natural Language Processing, Jianfei Yu

Dissertations and Theses Collection (Open Access)

In the past few decades, supervised machine learning approach is one of the most important methodologies in the Natural Language Processing (NLP) community. Although various kinds of supervised learning methods have been proposed to obtain the state-of-the-art performance across most NLP tasks, the bottleneck of them lies in the heavy reliance on the large amount of manually annotated data, which is not always available in our desired target domain/task. To alleviate the data sparsity issue in the target domain/task, an attractive solution is to find sufficient labeled data from a related source domain/task. However, for most NLP applications, due to …
