Ascat Wind Estimation At 2.5 Km Resolution Supported By Machine Learning Rain Detection, Joshua Benjamin Kjar

Theses and Dissertations

The Advanced Scatterometer (ASCAT) is a C-band scatterometer designed to be less sensitive to rain contamination than other higher frequency scatterometers. However, the radar backscatter is still affected by rain which increases error during wind estimation. The error can be reduced in rainy conditions by combining a rain backscatter model with the existing wind only (WO) backscatter model to perform simultaneous wind and rain (SWR) estimation. I derive and test several 2.5 km resolution rain backscatter models for ASCAT data which are used with the WO model to estimate the near surface winds. Various rain models optimal for different purposes …

Investigating Preservation Of Stable Isotope Ratios In Subfossil Deep-Sea Proteinaceous Coral Skeletons As Paleo-Recorders Of Biogeochemical Information Over Multimillennial Timescales, Danielle S. Glynn, Kelton W. Mcmahon, Owen A. Sherwood, Thomas P. Guilderson, Matthew D. Mccarthy

Graduate School of Oceanography Faculty Publications

Paleoproxy records in deep-sea proteinaceous coral skeletons can reconstruct past ocean conditions on centennial to millennial time scales. Commonly recovered subfossil specimens could potentially extend these archives through the Holocene. However, protein matrix stability and integrity of stable isotope proxies over multi-millennial timescales in such specimens have never been examined. Here we compare amino acid (AA) composition together with bulk and AA compound-specific carbon (δ13C) and nitrogen (δ15N) isotopes in live-collected and subfossil (∼9.6–11.6 kyrs BP) Kulamanamana haumeaae deep-sea coral specimens from the central Pacific to understand the effects of long-duration benthic oxic exposure on primary coral chemistry. We find …

Cerebrospinal Fluid Drainage For Prevention Of Spinal Cord Ischemia In Thoracic Endovascular Aortic Surgery-Pros And Cons, Hesham Ellauzi, Harendra Arora, John A. Elefteriades, Mohammad A. Zaffar, Rama Ellauzi, Wanda M. Popescu

Internal Medicine Articles

Thoracic endovascular aortic repair (TEVAR) carries a risk of spinal cord ischemia (SCI) which exerts a devastating impact on patient's quality of life and life expectancy. Although routine prophylactic cerebrospinal fluid (CSF) drainage is not unequivocally supported by current data, several studies have demonstrated favorable outcomes. Patients at high risk for SCI following TEVAR likely will benefit from prophylactic CSF drains. However, the intervention is not risk free, and thorough risk/benefit analysis should be individualized to each patient.

Competence And Bias In The Provision Of Transgender Mental Health, Taylor Dahlia Bolinger

Social Work Theses - Archive

Historically, clinicians have functioned as gatekeepers to access gender-affirming care for individuals identifying as transgender. However, current best practice standards by reputable professional associations have encouraged clinicians to minimize potential barriers for clients seeking gender-affirming care. This care includes hormone replacement therapy (HRT) and gender confirmation surgeries, and other gender-affirming interventions such as name and gender marker change. This study seeks to describe Texas clinicians’ attitudes toward transgender clients and their self-perceived competency to perform gender affirming care. Licensed mental health care clinicians were recruited from various professional associations to complete an anonymous internet-based survey on providing gender-affirming mental health …

Military veterans experience a transition process when returning to civilian life that involves reintegration across life domains. Reintegration has been shown to be a significant challenge for a contingent of former servicemembers that can be exacerbated by an erosion of social support networks. Difficulty accessing peers due to wider social trends away from community connectedness and geography have inspired the creation of virtual gathering spaces for a wide range of populations. The emerging evidence for peer-driven online support groups suggests the potential for facilitating development of new supportive interpersonal connections and improved access to tangible resources. The current study seeks …

Design, Fabrication, And Characterization Of Conjugated Polymeric Electrochemical Memristors As Neuromorphic/Integrated Circuits, Benjamin Grant

All Dissertations

Organic materials are promising candidates for future electronic devices compared to the complementing inorganic materials due to their ease of processability, use, and disposal, low cost of fabrication, energy efficiency, and flexible nature toward implementation as flexible and non-conformal devices.With that in mind, electrochemical materials have been widely demonstrated with commercial use as sensors, displays, and a variety of other electronic devices. As Moore's law predicts the increase in the density of transistors on a chip, the requirement to create either smaller transistors or the replacement of the transistor device entirely is apparent. Memory resistors, coined ``memristor", are variable resistive …

Open Educational Resources And Institutional Repositories: Roles, Challenges, And Opportunities For Libraries, James Hutson, Susan Edele, Elizabeth Macdonald, Paul Huffman, Nancy Messina, Maggie Pavone, Carla Mueller, Gabriela Romero

Faculty Scholarship

The adoption of digital-born, Open Educational Resources (OER) has been proven to improve student retention and learning outcomes, and OER has the flexibly to support multiple modalities of instruction. Institutional Repositories are uniquely situated to act as a platform to support and distribute content that can be created collaboratively between faculty researchers as well as students. However, faculty are still largely hesitant to adopt OER sources for a variety of reasons, not least among them being a lack of exposure and understanding of the potential benefits for both faculty and students in keeping curriculum affordable, up-to-date, and nimble through media-rich, …

Global Learning: Definition, Assessment, And Approaches, Jiangyuan Zhou

Journal of Global Education and Research

Global learning has become a fundamental aspect of international education. Yet, a clear understanding of global learning and how to develop it remain unclear. Using the dynamic systems approach, this paper analyzed the reasons, methods, and knowledge, skills, and attitudes(KSA) of global learning in higher education. Global learning is the higher education institutions’ critical response to globalization. It is the essential learning outcome of comprehensive internationalization of curriculum requiring students to develop KSA about the external world and their internal selves in their daily lives across local and global communities. With survey results from 142 undergraduate students in one U.S. …

Encountering American Higher Education: First-Year Academic Transition Of International Undergraduate Students In The United States, Masha Krsmanovic

Journal of Global Education and Research

This study explored how international undergraduate students perceive their academic transition into American higher education. Schlossberg’s (1984) 4S Transition Theory served as the framework for exploring what academic challenges, if any, international students experience during their first year of undergraduate studies in a new cultural and educational setting. The findings revealed that students’ academic transition into the U.S. higher education was characterized by difficulties in understanding the academic system of their new environment; overcoming educational, instructional and pedagogical differences; building social relationships with domestic students; and receiving the support necessary from the appropriate institutional services.

Immigrant Students And Global Education, Felipe A. Filomeno, Christopher Brown

Journal of Global Education and Research

Research on immigrant students in higher education often articulates a deficit narrative emphasizing the challenges immigrant students face in comparison to their native-born peers.
