Place, Preferences, And Policy: An Analysis Of Funding Education Along The Urban-Rural Divide, Kattalina Berriochoa

Graduate Doctoral Dissertations

Rural places are changing in unique ways compared to urban and suburban areas. Rural residents disproportionately experience geographic isolation, tax base loss, decreasing populations, and economies challenged by industrial shifts and declines. This leaves rural areas with increasing need for public investment but does not necessarily translate into increased public demand for these investments. In this work, I analyze the following puzzle: what explains geographical variation in individual preferences, which often appears contrary to collective interests? Specifically, I analyze variation in investment preferences for public education and seek to build a better understanding of the underlying dynamics that explain why …

Effects Of Visual Impairment On The Preparation, Response, And Recovery From The 2017 Hurricane Season In Puerto Rico, Kevin D. Mccormack

Graduate Doctoral Dissertations

The 2017 hurricane season in Puerto Rico brought rain and wind forces the likes of which had not been seen in 90 years on the island. Some say it will take at least ten years to recover from the damage caused to functional necessities such as roadways, assuming full recovery is possible. While the general populace in Puerto Rico struggled to recover, populations such as people with visual impairments experienced the struggle more acutely. Independent living, limited as it generally was before Hurricane Maria, was further compromised. There was a feeling of abandonment throughout the community of people with visual …

Coming To An Understanding: Daoist Rhetoric As Dialogue In Composition Studies, Veronica Anzaldua

Theses and Dissertations

Monological argumentation, based on Aristotelian principles, dominates composition pedagogy in the United States. With this model, students construct arguments in which they advocate for their own viewpoints. To make argumentation more dialogic, there exist various discourse models, including Daoist rhetoric, based on the ancient Chinese philosophy of Daoism. Its tenets have the potential to generate dialogic discourse in composition due to Laozi’s, Zhuangzi’s, and Sunzi’s principles. The recent cultural turn in composition studies opens space for the exploration of dialogic pedagogy. Dialogic pedagogies based on Daoist philosophies, with other recent pedagogical innovations, have the potential to promote deep, interconnected dialogue …

Development Of A Gpu-Based Real-Time Interference Mitigating Beamformer For Radio Astronomy, Jeffrey M. Nybo

Theses and Dissertations

Radio frequency interference (RFI) mitigation enables radio astronomical observation in frequency bands that are shared with many modern satellite and ground based devices by filtering out the interference in corrupted bands. The present work documents the development of a beamformer (spatial filter) equipped with RFI mitigation capabilities. The beamformer is intended for systems with antenna arrays designed for large bandwidths. Because array data post processing on large bandwidths would require massive memory space beyond feasible limits, there is a need for a RFI mitigation system capable of doing processing on the data as it arrives in real-time; storing only a …

Almost Homeomorphisms And Inscrutability, Michael Steven Andersen

Theses and Dissertations

“Homeomorphic'' is the standard equivalence relation in topology. To a topologist, spaces which are homeomorphic to each other aren't merely similar to each other, they are the same space. We study a class of functions which are homeomorphic at “most'' of the points of their domains and codomains, but which may fail to satisfy some of the properties required to be a homeomorphism at a “small'' portion of the points of these spaces. Such functions we call “almost homeomorphisms.'' One of the nice properties of almost homeomorphisms is the preservation of almost open sets, i.e. sets which are “close'' to …

Exploring The Efficiency Of Software-Defined Radios In 3d Heat Mapping, Andrew Scott Thomas

Theses and Dissertations

A common method of connecting to the internet is a wireless network. These networks can be monitored to discover the area of their coverage, but commercial receivers don't always provide the most accurate results. A software-defined radio was programmed to sniff wireless signals and tested against a commercial receiver and the results were compared. The results suggest that the software-defined radio performs at least as well as the commercial receiver in distance measurements and significantly better in samples taken per minute. It was determined that the software-defined radio is a viable replacement for a commercial receiver in 3D heat mapping.

Advanced Techniques For Carbon Nanotube Templated Microfabrication, Jason Matthew Lund

Theses and Dissertations

Carbon nanotube templated microfabrication (CNT-M) is a term describing a grouping of processes where carbon nanotubes (CNTs) serve a structural role in the fabrication of a material or device. In its basic form, CNT-M is comprised of two steps: produce a template made from carbon nanotubes and infiltrate the porous template with an additional material. Vertically aligned carbon nanotube (VACNT) templates can be grown to heights ranging from microns to millimeters and lithographically patterned to a desired form. Deposition of an existing thin film material onto a CNT template will coat all template surfaces and can produce a near solid …

Frontiers In Theory-Predicated Research In Youth Development: A Commentary, Richard Lerner

Journal of Youth Development

The field of youth development sits at the frontier of new opportunities for research and practice. These opportunities are enabled by innovations in theory and in theory-inspired research methods. Framed by relational developmental systems metatheory, dynamic systems models of youth development emphasize that every young person has the potential to change positively by aligning specific individual strengths and contextual resources that, together, can optimize the life paths of a young person. The methods linked to these theoretical models combine to help identify the specific links between an individual and his or her context that may maximize thriving across the adolescent …

Understanding Youths’ Educational Aspirations In The Somali Diaspora, Joanna Tzenis

Journal of Youth Development

This article shares findings from a 10-month qualitative longitudinal study that offer insight into the educational aspirations of American youth (grades 6-9) who belong to the Minnesota Somali diaspora and highlight the social and cultural influences that shape these aspirations. The findings show that while the majority of youth participants (at one point in the study) expressed that they wanted to become doctors in the future, these aspirations were informed by family values around helping others in Somalia—not an interest in medicine or science. The findings also demonstrate that through time, as the high school youth began to engage more …

Tumors of the conjunctiva and cornea comprise a large and varied spectrum of conditions. These tumors are grouped into two major categories of congenital and acquired lesions. The acquired lesions are further subdivided based on origin of the mass into surface epithelial, melanocytic, vascular, fibrous, neural, histiocytic, myxoid, myogenic, lipomatous, lymphoid, leukemic, metastatic and secondary tumors. Melanocytic lesions include nevus, racial melanosis, primary acquired melanosis, melanoma, and other ocular surface conditions like ocular melanocytosis and secondary pigmentary deposition. The most frequent nonmelanocytic neoplastic lesions include squamous cell carcinoma and lymphoma, both of which have typical features appreciated on clinical examination. …

Prognostication Of Uveal Melanoma Is Simple And Highly Predictive Using The Cancer Genome Atlas (Tcga) Classification: A Review., Carol L. Shields, Lauren A. Dalvin, Pornpattana Vichitvejpaisal, Mehdi Mazloumi, Arupa Ganguly, Jerry A. Shields

Wills Eye Hospital Papers

Purpose: The cancer genome atlas (TCGA) is a comprehensive project supported by the National Cancer Institute (NCI) in the United States to explore molecular alterations in cancer, including uveal melanoma (UM). This led to TCGA classification for UM. In this report, we review the American Joint Committee on Cancer (AJCC) classification and TCGA classification for UM from the NCI's Center for Cancer Genomics (NCI CCG) (based on enucleation specimens [n = 80 eyes]) and from Wills Eye Hospital (WEH) (based on fine needle aspiration biopsy [FNAB] specimens [n = 658 eyes]). We then compare accuracy and predictability of AJCC versus …

Trifocal Choroidal Melanoma In An Eye With Oculodermal Melanocytosis: A Case Report., Samuel J Fallon, Charlotte N Shields, Maura Di Nicola

Wills Eye Hospital Papers

We report a case of trifocal choroidal melanoma (three separate tumors) in a 48-year-old Caucasian female who had been followed for oculodermal melanocytosis since childhood. At presentation, no tumor was present and annual examination was advised. Seventeen years later, three choroidal melanocytic lesions were detected in the right eye. Growth of each was documented, enucleation was performed, and histopathology revealed three independent choroidal melanomas. The patient developed extensive liver and bone metastases and subsequently died. Oculodermal melanocytosis is a risk factor for the development of uveal melanoma and a potential marker for worse prognosis. Careful long-term follow-up is required.

Making The Case For The Use Of The Ksu Archives And Special Collections Through Interpretive Videos, Helen Thomas

This study investigates whether adult ESL programs in northern Mississippi are satisfactorily meeting those needs. Literature in the areas of second language acquisition, pedagogy, and adult ESL classroom research is reviewed, along with statistical background information relevant to the investigated geographic region. A qualitative methodological approach is employed, utilizing online, anonymous surveys to measure program characteristics and student …

Conflict Style And Marital Satisfaction In Black Intercultural Couples, Tiffanie James Parker

Doctoral Dissertations and Projects

Current literature suggests that culture-specific relationships exist between conflict styles and marital satisfaction; however, researchers have only focused on marriages between non-Westerners and Westerners. Very little research exists on how these variables function uniquely in marriages involving African American and African Caribbean individuals. This quantitative study examined the relationship between conflict style and marital satisfaction with and between African Caribbean and African American couples living in the United States. The research focused on three questions: (1) Will cultural differences between spouses influence the relationship between conflict styles and marital satisfaction? (2) Will there be any observable differences in conflict styles …

The Crucible Of History:How Apology And Reconciliation Created Modern Conceptions Of The Salem Witch Trials, Heaven Umbrell

Electronic Theses and Dissertations

For centuries, historians, authors, and amateur enthusiasts alike have been mesmerized by the Salem witch trials. Most of the literature focuses on the trials themselves and takes one of three approaches: anthropological; sociological; or conspiratorial. Recently Gretchen Adams, professor of history at Texas Tech University, approached the trials differently, focusing on memory. She narrowed on how the “specters of Salem” loomed over American cultural and public memory. Apart from Adams, little scholarly inquiry has focused on the aftermath of the trials, especially how it affected the people directly involved. This thesis will expand the historiography of the Salem witch hunt …

Potential Allelopathic Activity Of Dichloromethane Extract From The Leaves Of Talinum Paniculatum (Jacq.) Gaertn Against Cyperus Iria, Kevin C. Salamanez, Liezel Angelique L. Sabaupan, Arnoldus M. Mangao, Evelyn B. Rodriguez

Journal Article

This study focused on the isolation, characterization and allelopathic activity assessment of phytotoxic compounds present in the weed Talinum paniculatum (Jacq.) Gaertn. The leaves of T. paniculatum were sequentially extracted with petroleum ether, dichloromethane, ethyl acetate, and ethanol-water (1:1 v/v). Using the lettuce seed assay, the dichloromethane extract was found to be the most bioactive extract having an IC50 of 477 ppm. Phytochemical screening of the dichloromethane extract revealed the presence of saponins, steroids, terpenoids, and glycosides. Isolation of the major compound from the extract was carried out using open column chromatography. UV-Vis and IR spectral analyses, melting point determination, …

The Learning Clubs programme addresses both physical and mental child and maternal health. This study is an economic evaluation of a cluster randomised controlled trial of the impact of the Learning Clubs programme in Vietnam. It will be conducted from a societal perspective and aims to identify the cost-effectiveness …

Evaluating Antipsychotic Prescribing In The Intensive Care Unit And Across The Continuum Of Care, Michael Pasqualicchio, Heidi Clarke

All Publications

Purpose/Background: The 2018 Clinical Practice Guidelines for the Prevention and Management of Pain, Agitation/Sedation, Delirium, Immobility, and Sleep Disruption in Adult Patients in the ICU (PADIS) recommend against both typical and atypical antipsychotic use for delirium in critically ill patients. This recommendation is based on evidence showing that these medications are not associated with shorter durations of delirium, mechanical ventilation, intensive care unit (ICU) length of stay, or reduced mortality. There are many long term complications associated with the use of antipsychotics including QTc prolongation, extrapyramidal symptoms, metabolic abnormalities, and anticholinergic effects. Regardless, antipsychotics remain the most common medication used …

A Systematic Approach For Automatically Answering General-Purpose Objective And Subjective Questions, Lok Prasad Acharya

Theses and Dissertations

In this era of information explosion, people generally rely on the Internet, and more precisely, the search engines to get answers to their questions. However, what a search engine can do is just retrieve documents. Given some keywords, it only returns the relevant ranked documents that contain the keywords. Although users often want a precise answer to a question, they are left to extract answers from the documents themselves. This is where Automatic Question Answering (AQA) systems come into play. An AQA system takes questions in natural language as input and searches related answers in the set of documents and …

Social Groups Characterization And Dynamics: A Network Science Approach, Josemar Faustino Da Cruz

Theses and Dissertations

Over the course of our lives, we tend to transition through many social groups. From an early age, our first social group is our family, then we have our schoolmates, later in life, our coworkers, and likely another family. As we move from one group to another, we embed ourselves in the dynamics of social groups’ losses and gains of new members. These dynamics are a complex system of interactions, which at scale, form the structural basis of our societies. In many years of sociological research, the details of social group interactions remained poorly understood. Certainly, not because of lack …

The Ascension Of Jesus Christ: Its Role In Redemption From A Latter-Day Saint Theological Perspective, William Perez

Theses and Dissertations

Mosiah 18:2 lists the ascension of Jesus Christ as one of the atoning acts that brings about redemption. Although many faith traditions have developed a theology about the significance of the ascension, the topic has not been covered at length within The Church of Jesus Christ of Latter-day Saints. This thesis explores the ascension of Jesus Christ and its implications for humanity from the perspective of Latter-day Saint beliefs.The ascension of Jesus Christ can be considered the culmination, even the capstone of His atonement. There are sufficient sources within Latter-day Saint canon and the teachings of general authorities to support …
