The Acquisition And Analysis Of Electroencephalogram Data For The Classification Of Benign Partial Epilepsy Of Childhood With Centrotemporal Spikes, Jessica A. Scarborough

Master's Theses

In this thesis, I will expand upon each step in the process of acquiring and analyzing electroencephalogram (EEG) for the classification of benign childhood epilepsy with centrotemporal spikes. Despite huge advancements in the field of health informatics—natural language processing, machine learning, predictive modeling—there are significant barriers to the access of clinical data. These barriers include information blocking, privacy policy concerns, and a lack of stakeholder support. We will see that these roadblocks are all responsible for stunting biomedical research in some way, including my own experiences in acquiring the data for the second chapter of this thesis.

This second chapter …

Aspirations As A Component Of Life Satisfaction: A Look At Female Microfinance Borrowers In Oaxaca, Mexico, Joseph E. Kemler

Master's Theses

This research is an extension to the Oaxaca Hope Project by B. Wydick and T.J. Lybbert. How does an individual gauge her own satisfaction with life? Previous research has noted that many domains make up overall life satisfaction, i.e. career satisfaction, family life satisfaction & social life satisfaction. A burgeoning topic in this regard is the role that aspirations play in life satisfaction. Using survey data from female microfinance borrowers in Oaxaca, Mexico this project attempts to analyze the affect previous aspirations have on life satisfaction. By creating an “aspirational window” we objectively attempt to gauge the relationship between “high” …

Competitive Mothers: An Experimental Study Of Female Competitiveness And Polygamy In Togo (West Africa), Aminata Cissokho

Master's Theses

Are women in a patriarchal society like Togo as competitive as men? How does being a parent, in a polygamous vs. monogamous marriage and having high income affect one’s willingness to compete? With an incentivized experiment, we explore whether there are gender differences in selecting into competitive environments, especially when the incentives switch from cash to voucher. This experiment is conducted in Togo, West Africa, with 428 subjects including females-males, parent-non parent. Overall, the findings reveal no significant differences between the females and males’ willingness to compete. Female parents are more competitive than male parents regardless of the incentive. Subjects …

C(Sp2)–H Functionalizations Employing 2-Aminophenyl-1h-Pyrazole As A New Removable Directing Group, Wan-Chen Lee

Master's Theses

2-Aminophenyl-1H-pyrazole (2-APP) was discovered as a novel removable bidentate directing group for copper-mediated aerobic oxidative C(sp2)–H bond amidation and sulfonamidation bearing a wide range of sulfonamides, When Cu(OAc)2 was employed as the copper source, 1,1,3,3-tetramethylguanidine (TMG) as an organic base, the reaction, optimally carried out overnight in DMSO at 80 °C in open air, produced a variety of products in moderate to excellent yields. In addition, C(sp2)–H bond chlorination has been developed by using this auxiliary, employing trichloroacetamide as a new chlorine source. Furthermore, this unprecedented directing group also can assist copper-mediated regio-selective hydroxylation, and ortho-alkynylation/annulation by using Cu(OAc)2 as …

Ambiguity Aversion: Adoption, Uptake, And Trends, Adam Franklin

Master's Theses

What is ambiguity aversion and what is its role as a determinant of technology adoption? This study develops and implements a novel ambiguity preference instrument in the context of an ongoing RCT pilot program in southwest Uganda promoting adoption of an improved variety of sweet potato. No correlation between ambiguity aversion and crop adoption is observed, although it is suspected that RCT treatment arms including supply- and demand-side information reduced the ambiguity of the new variety, probably overcoming any ambiguity-preference-related constraints and clouding the picture. Methodological lessons learned regarding the development and implementation of an apporopriate ambiguity preference measure point …

Centering Error For Range Poles, Kevin D. Franklin

Master's Theses

A land surveyor makes accurate measurements using knowledge, physical dexterity, and properly calibrated equipment. All measurements contain errors, but the professional surveyor is mindful of the various sources and consciously works to minimize them based on experience and informed decision making. One such error source is the level vial, a standard component of numerous survey instruments and accessories. This paper derives expected miscentering error from a circular sprit level with an example using a global navigation satellite system (GNSS) range pole as commonly used for real-time kinematic positioning. We demonstrate that when the length of a 2-m, 40 min:2 mm, …

Effects Of Ankle Weights On Metabolic Response And Muscle Activity On A Lower Body Positive Pressure Treadmill 2017, Saige Hupman

Master's Theses

Lower body positive pressure (LBPP) treadmills are growing in popularity for rehabilitative use, as the benefits of exercising at partially supported body weight may induce faster recovery. It is unknown if there are certain practices that increase exercise intensity while maintaining positive effects of LBPP. Adding ankle weights when walking or running could increase intensity of rehabilitation programs while maintaining the comfort of supported body weight. PURPOSE: To measure metabolic response (VO2, RER, HR, Caloric expenditure), RPE, and lower limb electromyography (EMG) amplitudes of LBPP treadmill walking and running with and without ankle weights. METHODS: Sixteen participants (Age: 21.94 ± …

Philosophers On The Fringe: Albert Schweitzer, Liberty Hyde Bailey, Aldo Leopold, And The Wrongful Polarization Of Environmentalist History 2017, Minnie A.M. Lauzon

Master's Theses

This thesis includes three articles (chapters) intending to encourage clarification of an area of environmental history that has not received adequate attention since the publication of Roderick Nash’s Wilderness and the American Mind. Since its publication in 1967, little research has been dedicated to understanding the scholarly or philosophical influence Albert Schweitzer and Liberty Hyde Bailey had on Aldo Leopold. Since my undertaking of this topic, I have established two primary goals. First, I want to provide clarification to environmentalists, academics, and the populace at large that environmentalism does not have to be bound by rules and convention, but can …

Actuator Disk Theory For Compressible Flow, Htet Htet Nwe Oo

Master's Theses

Because compressibility effects arise in real applications of propellers and turbines, the Actuator Disk Theory or Froude’s Momentum Theory was established for compressible, subsonic flow using the three laws of conservation and isentropic thermodynamics. The compressible Actuator Disk Theory was established for the unducted (bare) and ducted cases in which the disk was treated as the only assembly within the flow stream in the bare case and enclosed by a duct having a constant cross-sectional area equal to the disk area in the ducted case. The primary motivation of the current thesis was to predict the ideal performance of a …

Age, Growth, And Reproduction Of Vermilion Snapper (Rhomboplites Aurorubens) In The North-Central Gulf Of Mexico, Trevor Dalton Moncrief

Master's Theses

Vermilion Snapper is a commonly harvested species of reef fish in the northern Gulf of Mexico (GOM). It supports both a large commercial and popular recreational fishery, however knowledge of this fish’s life history is limited spatially. Non-linear curve fitting was used to estimate growth parameters and Akaike information criteria (AIC) was used to determine relative model fit. The 2-parameter von Bertalanffy growth function provided the best model fit and lowest AIC score. Histological examination indicated that Vermilion Snapper are batch spawners with asynchronous oocyte development. Additionally, 17% of Vermilion Snapper in the actively spawning phase containing 24 hour POF’s …

Towards A Better Understanding Of Zebrafish Sleep Behavior, Kanza Musarrat Khan

Master's Theses

Sleep serves many vital functions in humans, ranging from energy restoration to memory consolidation and information integration. Sleep deprivation is linked to worsened physiological states and psychological conditions. Zebrafish are an emerging model in neurobehavioral research and have recently demonstrated great utility in the study of sleep. This teleost species possesses several of the same neurotransmitter and neuropeptide systems that are involved in the regulation of sleep and waking rhythms in higher order mammals. Previous study of these animals has revealed a differential gene and proteomic expression following sleep deprivation through changes in environmental stimuli. The present study sought to …

Corgi: Compute Oriented Recumbent Generation Infrastructure, Christopher Allen Hunt

Master's Theses

Creating a bicycle with a rideable geometry is more complicated than it may appear, with today’s mainstay designs having evolved through years of iteration. This slow evolution coupled with the bicycle’s intricate mechanical system has lead most builders to base their new geometries off of previous work rather than expand into new design spaces. This crutch can lead to slow bicycle iteration rates, often causing bicycles to all look about the same. To combat this, several bicycle design models have been created over the years, with each attempting to define a bicycle’s handling characteristics given its physical geometry. However, these …

Silent Communication Device, Christopher Wayne Schutter

Master's Theses

Oral communication has constituted as a necessary aspect of how people interact with one another, but there are always situations where this form of communication can create distractions, irritation, or even danger. Take for example, a student in a laboratory who needs to communicate effectively with a lab partner without creating a distraction to those trying to work around said student or a soldier on a battlefield who needs to relay information effectively to his or her comrades without revealing his or her position to the enemy. It becomes apparent that people need a more exclusive form of communication in …

Gpumap: A Transparently Gpu-Accelerated Map Function, Ivan Pachev

Master's Theses

As GPGPU computing becomes more popular, it will be used to tackle a wider range of problems. However, due to the current state of GPGPU programming, programmers are typically required to be familiar with the architecture of the GPU in order to effectively program it. Fortunately, there are software packages that attempt to simplify GPGPU programming in higher-level languages such as Java and Python. However, these software packages do not attempt to abstract the GPU-acceleration process completely. Instead, they require programmers to be somewhat familiar with the traditional GPGPU programming model which involves some understanding of GPU threads and kernels. …

Comparing Groundwater Model Calibration Approaches: Does An Optimized Model Better Reflect Reality When Both Flow And Transport Observations Are Applied?, Vivian E. Sovinsky

Master's Theses

This research compares two approaches to the application of formal calibration methods to groundwater modeling: sequential and combined. There exists research, both theoretical work and field studies, that point to improved estimation of hydraulic parameters when multiple types of observations, flow and transport, are applied simultaneously. There also exist theories about why combined calibration might not be compatible with the differing mathematical basis of flow compared to transport. This research has taken a closer look at the mechanisms at work by comparing these approaches when the input parameters are known. Using stochastic methods instead of field data, the original input …

A Single Packer Method For Characterizing Water Contributing Fractures In Crystalline Bedrock Wells, Neil Flahive

Master's Theses

The water levels and water quality obtained from open borehole wells in fractured bedrock are flow weighted averages that are a function of the hydraulic heads and transmissivities of water contributing fractures, which are rarely known. Without such knowledge using water levels and water quality data form fractured bedrock wells to assess contaminant conditions can be highly misleading. This study demonstrates a cost effective single packer fracture characterization method that can be used in fractured bedrock to determine the hydraulic heads and transmissivities of individual fracture zones. The method entails inflating a pipe plug to isolate sections of an open …

Measuring And Improving Seniors' Access To Medical Facilities, Angelika Zygo

Master's Theses

The travel behaviors of older adults often shift as they retire, begin second careers and make residence location choices geared towards aging in place. Those who rely on transit as their primary mode of transportation can face many accessibility and connectivity challenges when traveling to basic amenities due to their unique travel behaviors and declining mobility with advanced age. First chapter of this thesis focuses on a subset of these travel behaviors through a literature review then evaluates the ability of public transportation to meet the specific mobility needs of older adults (defined in three ways: as those adults >65 …

In addition to these improvements, investigators are also interested to evaluate the association between ART treatments and the body habitus changes of the HIV patients. It is unclear that which body habitus change outcomes are more greatly associated with what type of ART treatments and how those effects could vary depending on context and sample characteristics.

Objective: To obtain overall effect sizes for the body habitus change outcome variables (weight, body mass …

Depressive Symptoms, Neuropsychological Functioning, And Self-Management In Youth With Spina Bifida: Direct, Mediating, And Reciprocal Pathways, Alexa Stern

Master's Theses

Although successful self-management of health care responsibilities is critical to meeting the developmental demands associated with the transition to adulthood in youth with spina bifida (SB), research on individual factors impacting self-management in this population is sparse. Given the increased risk for cognitive deficits and development of depressive symptoms in this population, this study utilized a longitudinal, multi-method, multi-informant design to examine two pathways through which depressive symptoms and neuropsychological dysfunction may be associated with medical autonomy and adherence in youth with SB.

Bootstrapped mediation analyses revealed that teacher-reported depressive symptoms significantly mediated the respective relationships between attention and working …

A Qualitative Analysis Of A Team's Experience Of Coping With Bereavement After The Death Of A Head Coach, Matthew Paul Gonzalez

Master's Theses

The consequences of coping with death as an athlete have been documented in the literature by a variety of studies. However, these studies have remained largely focused on coping with the death of a teammate. This study examined the inter- and intrapersonal impact of experiencing the death of a head coach. Experiencing the death of a head coach during the season may have profound and varied psychosocial consequences for all members of a team. A collegiate team was identified as having experienced the death of its head coach during his tenure and from that team five participants (four players and …

Diet Induced Obesity Alters Muscle Spindle Afferent Function In Adult Mice, Lubayna Elahi

Master's Theses

Individuals with obesity are more likely to fall and exhibit balance instability. The reason for this is likely multifactorial, but there is some evidence that sensory function is impaired during obesity. We tested the hypothesis that muscle proprioceptor function is compromised in a mouse model of diet induced obesity. We used an in vitro muscle-nerve preparation to record muscle spindle afferent responses to physiological stretch and sinusoidal vibration. We compared the responses of mice on a control diet (10% kcal fat) with those eating a high fat diet (60% kcal fat) alone or in combination with either aspirin (120mg/kg/day in …

The Study Of The Development Of Negation In Bilingual Spanish/English And Monolingual English Speakers, Isabel Cristina Verduzco

Master's Theses

Problem

Negation is one of the first concepts learned early during childhood and one of the most important ones for communication. Current studies focus on how negation is developed universally in each specific language and how it is governed by patterns of acquisition, however, there are factors that may affect this process. How does learning two languages simultaneously affect the normal development of negation? Analyzing how the exposure to two different languages affects the normal development of negation is important for understanding how bilingualism influences normal language development. This study is also important for the analysis of speech and language …
