Community College Students’ Perceived Value Of High School Career And Technical Education Program Experiences, Martin Douglass

CUP Ed.D. Dissertations

The goal of this qualitative, narrative inquiry study was to explore the voices of community college students who have taken Career and Technical Education (CTE) while in high school, investigate if they perceived value from their high school CTE classes, and determine how those experiences impacted their high school and college educations (cf. Association for Career and Technical Education, 2016; American Institutes for Research, 2013; Southern Regional Education Board, 2008). The central research question for the dissertation was: What value do local community college students believe their high school Career and Technical Education program participation provided? The screening survey had …

A Novel Splitting Beam Laser Extensometer Technique For Kolsky Tension Bar Systems, Colin Loeffler

Mechanical Engineering Research Theses and Dissertations

The Kolsky (Split Hopkinson) Bar has become a well-known and established experimental technique for characterizing the mechanical behavior of materials subjected to dynamic loading conditions. Kolsky bar based experimental techniques facilitate the application of controlled and repeatable dynamic loading conditions to a specimen as well as the high resolution measurement of the resulting mechanical response. In recent decades the technique has been refined and adapted to provide more complex dynamic stress-states beyond uniaxial compression. However, the increasing complexity of the experimental apparatus introduces uncertainty to the traditional specimen deformation measurement techniques.

In this thesis, a direct non-contact optical measurement technique …

Arts Integration In The Public Elementary School General Education Classroom, Norma Quinones

Theatre & Dance ETDs

ABSTRACT

In 2017, the U.S. Department of Education’s Nations Report Card disclosed performance trends among fourth and eighth grade students in New Mexico. Fourth graders were significantly below the national average in math and reading, while eighth graders were also performing below the national average (U.S. Department of Education). How can New Mexico public elementary school students fulfill their learning potential? Extensive research shows that arts integrated instruction is associated with student achievement. It outlines arts integration as a multidisciplinary form of teaching across the curriculum to transform teaching and learning at the elementary school level to change such statistics. …

Alterations In Resting State Functional Connectivity Associated With Alcohol Use Severity And Impulsivity In A Community Sample, Elena R. Stein

Psychology ETDs

Alcohol Use Disorder (AUD) is characterized by neurocognitive and behavioral impairments including the multidimensional construct of impulsivity. Increased impulsivity is both a risk factor for, and a consequence of problematic alcohol use. Individuals with AUD exhibit alterations in neural circuitry when compared to those who do not have AUD. These circuit-level changes in AUD may underlie the difficulties that these individuals experience with heightened impulsivity. The present study uses data-driven resting state functional connectivity (rsFC) methodology to examine the differences in intrinsic functional networks between individuals with AUD and those who are social drinkers (SD). Participants in this secondary data …

Precaspian Isthmus Emergence Triggered The Early Sakmarian Glaciation (Paleontologic, Sedimentologic And Geochemical Proxies), Vladimir I. Davydov

Geosciences Faculty Publications and Presentations

The sub-meridional seaway that connected Paleo-Arctic and Paleo-Tethys basins was one of the most important geographical attributes of the Late Paleozoic Pangea landscape, paleogeography and paleoclimate. Existing models about the timing of the disconnection of the Paleo-Arctic and the Paleo-Tethyan oceans is very controversial and poorly documented. Warm-water benthic foraminifera (WWBF) were utilized to establish the precise timing of the closure of the Urals-Precaspian-Paleo-Tethys Seaway (UPTS) during Cisuralian time. The WWBF of Paleo-Tethys and those of the Ural-Precaspian Basins during the Gzhelian-Asselian, display a considerably high level of similarity. Beginning from the Sakmarian, the faunas of these two regions became …

Spatial Exploration Of Trace Metals In Near-Surface Water And Soil In The Bolivian Altiplano, Lizzie Wilson

Civil and Environmental Engineering Theses and Dissertations

We analyzed soil and groundwater samples from the Bolivian Altiplano for trace metal concentrations, correlations and partitioning trends. Total digestion, sequential extraction and loss on ignition experiments were performed on soil samples. We ran aqueous samples on an ICP-MS. Results were analyzed to identify trace metal concentrations and find any significant correlations. We generated interpolated maps in ArcGIS to spatially analyze results. Results for elevated concentrations of interest were divided into sub-groups of organophilic metals, oxoanions and divalent metals and include vanadium, arsenic, selenium, zinc, nickel, lead, cobalt, uranium, copper and manganese. These elements are likely naturally sourced. We found …

Non-Classical Plate Models Incorporating Microstructure And Surface Energy Effects: Their Variational Formulations And Applications, Gongye Zhang

Mechanical Engineering Research Theses and Dissertations

In this dissertation research, new non-classical models for Kirchhoff and Mindlin plates are developed and applied to study band gaps for flexural wave propagation in composite plate structures.

In Chapter 2, a new non-classical model for a Kirchhoff plate resting on an elastic foundation is developed using a modified couple stress theory, a surface elasticity theory and a two-parameter elastic foundation model. A variational formulation based on Hamilton’s principle is employed, which leads to the simultaneous determination of the equations of motion and the complete boundary conditions and provides a unified treatment of the microstructure, surface energy and foundation effects. …

Optical Micro-Seismometer Based On Evanescent Field Perturbation Of Whispering Gallery Modes, Jaime Da Silva

Mechanical Engineering Research Theses and Dissertations

This thesis proposes a light-weight, compact, and accurate optical micro-seismometer that could be used in many applications, such as planetary exploration. The sensor proposed here is based on the principle of whispering gallery optical mode (WGM) resonance shifts of a dielectric micro-resonator due to disturbances of its evanescent field. The micro-seismometer could be used in place of the traditional bulky seismometers. The design of a waveguide-resonator and mechanical structure to disturb the evanescent field are presented. A proof-of-concept a seismometer model that uses a 5µm ring resonator is numerically tested with actual seismic data. The results show that a WGM-based …

Screen Time, Sleep, And Mental Health: An Investigation Of Electronics Use And Sleep Habits, Robert Nicks

Electronic Theses and Dissertations

Internet addiction (IA) is classified as a compulsive-impulsive behavior disorder involving excessive use of the internet, withdrawal, tolerance, and negative repercussions (Block, 2007). Internet usage is becoming more widespread across all industrialized people, and younger people are using the internet more and more as it becomes more ubiquitous (Rideout, Foehr, & Roberts, 2010). The purpose of the current study is to investigate internet usage habits, sleep disturbance, and IA as it appeared in a national United States sample, and a sample seeking clinical psychological help in the Southwestern United States. The results of the current study suggested that IA predicted …

Syntheses Of A Tin (Iv) Meso-Tetra(4-Pyridyl) Porphyrin Dichloride-Tetrachlorobis (Bipy)2 Ruthenium (Ii) Complex And Studies Of Photophysical Properties Of 1-Nitropyrene, Phillip Sharp

Electronic Theses and Dissertations

Development of a photosensitizer that can work in both aerobic and anaerobic environments would increase the robustness of the cancer treatment known as photodynamic therapy. The development of a photosensitizer was first attempted by synthesizing a tin (IV) meso-tetra (4-pyridyl) porphyrin dichloride-tetrachlorobis (Bipy)₂ ruthenium (II) complex. The synthesize of the tin porphyrin was done by a method from literature and had a percent error of 31.58 and 37.31 when comparing the theoretical percentages of carbon (55.39) and nitrogen (12.92) meaning that photosensitizer was not synthesized.

The second type of chromophore that was studied was 1-nitropyrene do determine if it …

Delineation Of Karst Potential Using Lidar And Gis Analyses, Fort Hood Military Installation, Texas, Colby Reece

Electronic Theses and Dissertations

ABSTRACT

Traditional karst surveys require extensive field investigations to completely characterize large areas. They are often time-consuming, requiring up to several years to collect and categorize data. Bias is given to areas that are most easily accessible and false negatives are common. The implementation of geographic information systems (GIS) has aided in the aggregation and standardization of karst data; however, these systems have also been used to develop terrain models that allow the user to remotely delineate sinkholes and other surficial features. The Fort Hood Military Installation is a karst landscape that has been altered significantly for use in military …

Quantum Extension Of The Kruskal Spacetime, Abhay Ashtekar, Javier Olmedo, Parampreet Singh

Faculty Publications

A new description of macroscopic Kruskal black holes that incorporates the quantum geometry corrections of loop quantum gravity is presented. It encompasses both the "interior" region that contains classical singularities and the "exterior" asymptotic region. Singularities are naturally resolved by the quantum geometry effects of loop quantum gravity. The resulting quantum extension of spacetime has the following features: (i) It admits an infinite number of trapped, anti-trapped and asymptotic regions; (ii) All curvature scalars have uniform (i.e., mass independent) upper bounds; (iii) In the large mass limit, all asymptotic regions of the extension have the same ADM mass; (iv) In …

Measurement Of The Radial Mode Spectrum Of Photons Through A Phase-Retrieval Method, Saumya Choudhary, Rachel Sampson, Yoko Miyamoto, Omar S. Magaña-Loaiza, Seyed Mohammad Hashemi Rafsanjani, Mohammad Mirhosseini, Robert W. Boyd

Faculty Publications

We propose and demonstrate a simple and easy-to-implement projective-measurement protocol to determine the radial index p of a Laguerre–Gaussian (LGlp) mode. Our method entails converting any specified high-order LG0p mode into a near-Gaussian distribution that matches the fundamental mode of a single-mode fiber (SMF) through the use of two phase screens (unitary transforms) obtained by applying a phase-retrieval algorithm. The unitary transforms preserve the orthogonality of modes before the SMF and guarantee that our protocol can, in principle, be free of crosstalk. We measure the coupling efficiency of the transformed radial modes to the SMF for different pairs of phase …

Triple Sulfur Isotope Relationships During Sulfate-Driven Anaerobic Oxidation Of Methane, Shanggui Gong, Yongbo Peng, Huiming Bao, Dong Feng, Xiaobin Cao, Peter W. Crockford, Duofu Chen

Faculty Publications

© 2018 Elsevier B.V. Sulfate-driven anaerobic oxidation of methane (SD-AOM) plays a critical role in regulating the global methane budget. Determination of the diagnostic triple isotope exponent θ33 (≡ln33⁡α/ln34⁡α) for SD-AOM can help to identify and quantify microbial sulfate reduction via SD-AOM in the environment. The history of Earth's surface redox conditions can also be examined through the measurement of triple sulfur isotope compositions in sedimentary rocks. Due to difficulties in both culturing anaerobic methanotrophs and sampling pore-water sulfate in SD-AOM-dominated environments, however, the θ33 values for the processes of SD-AOM have not been constrained. We propose that a set …

Classical And Quantum Aspects Of Electric-Magnetic Duality Rotations In Curved Spacetimes, Ivan Agullo, Adrian Del Rio, Jose Navarro-Salas

Faculty Publications

It is well known that the source-free Maxwell equations are invariant under electric-magnetic duality rotations, F→Fcosθ+F sinθ. These transformations are indeed a symmetry of the theory in the Noether sense. The associated constant of motion is the difference in the intensity between self-dual and anti-self-dual components of the electromagnetic field or, equivalently, the difference between the right and left circularly polarized components. This conservation law holds even if the electromagnetic field interacts with an arbitrary classical gravitational background. After reexamining these results, we discuss whether this symmetry is maintained when the electromagnetic field is quantized. The answer is in the …

Design, Synthesis, And Evaluation Of C5 Substituted Carbapenem Antibiotics To Counter Resistant Pathogens, Noora Mohammed S.A Al-Kharji

Chemistry Theses and Dissertations

The 21st century has seen a dramatic acceleration in the evolution of bacterial resistance. Many classes of commercial antibiotics, including most current commercial β-lactams, were structurally optimized to counter 20th century pathogens. The carbapenems represent the most potent and broadest spectrum of the β-lactams, representing crucial last line agents to treat lifethreatening infections. While the 21st century has seen the appearance of carbapenem-resistant strains, the basic substitution pattern of commercial carbapenem antibiotics has remained constant, other than minor modifications at the C2 position. This research will investigate whether substitution at an atypical carbapenem position, the C5 position, can improve the …

The Installation Of The Human: Whiteness, Religion, And Racial Capitalism, Benjamin Robinson

Religious Studies Theses and Dissertations

Over the past thirty to forty years, the academic study of religion has brought the category of religion into crisis, unveiling its Christian architecture and its formation as a settler-colonial category of European expansion. While the proliferation of research on the genealogy of religion has opened new and important vantages for study, we remain conflicted about what is at stake. In this dissertation, I argue that the modern-colonial construction of religion is organized by a racial-theological operation that categorically separates people into humans, subhumans, and nonhumans, by which the social, economic, and political inequalities of racial capitalism have been made …

Racial Integration And White Supremacy In America: Can America Integrate Its Power Structures And Liberate Them From White Supremacy, Billy Lane

Graduate Liberal Studies Theses and Dissertations

Neither the presence of black people in predominantly white spaces nor the appropriation of black culture are indicators of racial justice. Power structures must be integrated even more so than subdivisions, classrooms, breakrooms, church pews, and pop culture. This thesis will explore the absence of African-American leadership from the highest ranks of our power structures that are central to contemporary life and the dynamics within each of these power structures that help to protect white supremacy and therefore maintain segregation.

Leveraging Grammars For Openmp Development In Supercomputing Environments, Samuel Hunter

Computer Science and Engineering Theses and Dissertations

This thesis proposes a solution to streamline the process of using supercomputing re- sources on Southern Methodist University’s ManeFrame II supercomputer. A large segment of the research community that uses ManeFrame II belong outside of the computer science department and the Lyle School of Engineering. While users know how to apply compu- tation to their field, their knowledge does not necessarily extend to the suite of tools and operating system that are required to use ManeFrame II. To solve this, the thesis proposes an interface for those who have little knowledge of Linux and SLURM to be able to use …

Between Developed And Emerging Markets: Globalization Of Large Consumer Good Enterprises, Christine Savino Ms.

Honors Scholar Theses

A few years ago, The Economist promulgated that “the only way that companies can prosper in [emerging] markets is to cut costs relentlessly and accept profit margins close to zero” (The Economist, 2010). Likewise, according to the World Bank’s 2018 Ease of Doing Business Index[1], the least ranked countries (#94 and under out of 190 countries) are solely undeveloped and developing, while the top 20 countries are solely developed economies (World Bank, 2018). It has been long held that emerging markets[2][3] are non-strategic investments for multinational expansion, and that business giants from …
