“El Negro Sin La Oreja”: A Dialectical Approach To The Blackness In Dominican Identity, Kevin E. Nicholes

Institute for the Humanities Theses

This master’s thesis examines ideologies of whiteness through the erasure and denial of blackness in the Dominican Republic and explores the manner in which racial identity has been reinforced and contested. A dialectical approach is utilized to analyze the discourse around the history of the Dominican Republic and a textual analysis is also employed to assist in supporting the findings. The rationale for this study is to access how whiteness became synonymous with Dominicanness and to resuscitate the blackness of Dominican identity which has been relegated to the classification of the “other”. Therefore, drawing conclusions as to how Dominicans

Characterization Of 3-Ester And 3-Carbamate Derivatives Of N-Acetyl-D-Glucosamine And Their Use In Controlled Drug Delivery, Consuelo Garcia

Chemistry & Biochemistry Theses & Dissertations

Low molecular weight gelators (LMWGs) are a class of compounds which reversibly form a network that traps solvents to form gels. Gelation by LMWGs is driven solely by non-covalent interactions such as hydrogen bonding, π - π stacking, and hydrophobic interactions. LMWGs can be designed such that the gel-sol and sol-gel transitions happen as a response to a specific stimulus. These stimulus responsive gels or “smart” gels can be used in a wide variety of applications including tissue regeneration, biosensing, and controlled drug delivery.

Among the different types of compounds that are LMWGs, carbohydrate based systems are especially interesting. Carbohydrates …

Lignin Contribution To The Global Carbon Pool: Investigating The Abiotic Modification Of Lignin By Reactive Oxygen Species, Derek Charles Waggoner

Chemistry & Biochemistry Theses & Dissertations

Evidence suggests that reactive oxygen species (ROS), largely generated through photochemical processes, are important in transforming the chemical composition of the large pool of terrestrially-derived dissolved organic matter (DOM) exported from land to water annually. However, due to the challenges inherent in isolating the effects of individual ROS on DOM composition, the role of ROS in the photochemical alteration of DOM remains poorly characterized. The main focus of the studies within this dissertation aim to more thoroughly characterize the alterations to lignin, used as an analog for terrestrial DOM, resulting from reactions with ROS.

To investigate the possibility that the …

An increasing trend in the brominated-trihalomethane to total-trihalomethane concentration ratio from 2001 to 2016 in the Virginia Beach water distribution system was established and investigated. This study aimed at identifying factors contributing to fluctuations in trihalomethane speciation in finished water. Reservoir management practices, treatment processes, and source water conditions were examined to quantitatively and qualitatively discern the impact of their variations on finished water THM speciation. Data on water quality constituents and parameters from the Moore’s Bridges Treatment Facility and within the Virginia Beach distribution system were examined to interpret spatial and temporal relationships with trihalomethane concentrations using established research …

Influence Of Tides And Mesoscale Eddies In The Ross Sea, Stefanie Lynn Mack

OES Theses and Dissertations

The Ross Sea is the most biologically productive region in the Southern Ocean. Primary production is controlled by dissolved iron (dFe), a limiting micronutrient. The main focus of this thesis, motivated by the PRISM-RS project, is to investigate how tides and mesoscale eddies affect the pathways of dFe to the surface ocean.

A regional ocean model with four hindcast simulations are used. Tidal forcing is added to simulations and mesoscale eddies are resolved by changing the horizontal grid resolution from 5 to 1.5 km. Simulations cover 1.5 years, ending at the time of the PRISM-RS cruise in early 2012. An …

Multi-Material Mesh Representation Of Anatomical Structures For Deep Brain Stimulation Planning, Tanweer Rashid

Computational Modeling & Simulation Engineering Theses & Dissertations

The Dual Contouring algorithm (DC) is a grid-based process used to generate surface meshes from volumetric data. However, DC is unable to guarantee 2-manifold and watertight meshes due to the fact that it produces only one vertex for each grid cube. We present a modified Dual Contouring algorithm that is capable of overcoming this limitation. The proposed method decomposes an ambiguous grid cube into a set of tetrahedral cells and uses novel polygon generation rules that produce 2-manifold and watertight surface meshes with good-quality triangles. These meshes, being watertight and 2-manifold, are geometrically correct, and therefore can be used to …

Factors Influencing Health Outcomes Across The Least, Average And Healthiest States In America, Somayeh Hooshmand

School of Public Service Theses & Dissertations

Although there is a growing literature that uses national and international data to investigate health outcomes and their link to the determinants of health, empirical studies on whether or not there is a causal relationship between health outcomes and the determinants of health, to our knowledge, has not been generally done previously. To fill this gap, the main focus of this dissertation is to empirically analyze the relationship existing between health determinants and health outcomes among the least healthy state (Mississippi), the middle ranked state (Virginia) and the healthiest state (Hawaii) as measured by American Health Ranking (AHR). This study …

Learning While Using An Instructional Simulation, Tayyaba Batool

STEMPS Theses & Dissertations

Learner control is thought to be valuable by some scholars who believe that it allows learners to adapt instructions to their needs while reducing cognitive load (Mayer & Moreno, 2003). Although learner control offers some advantages to the learner, the importance of an instructor cannot be denied. In instructor-controlled settings the instructor provides guidance to the learners. Direct instructional guidance provides information to the learner that explains the concepts and procedures that are to be learned along with the instructional strategy support that is compatible with human cognitive architecture (Kirschner, Sweller, & Clark, 2006). This study compared the effects of …

What Do You Believe? School Leaders And An Ideology Of Achievement, Andrew T. Lloyd

Educational Leadership & Workforce Development Theses & Dissertations

Beliefs about achievement impact the educational experiences of students. The mainstream ideology of achievement espouses that anyone can be successful as long as they put forth effort and work hard. This belief fails to account for systemic barriers that have limited historically marginalized groups of people from achieving. Research has focused on the beliefs of teachers with scant research done on the beliefs of school leaders. This study focused on what school leaders believe about achievement and how it impacts their daily practice. In addition, the ideologies of the school leaders were compared and contrasted with an ideology rooted in …

A Comparative Study Of The Effects Of External Selection On Settleability And Formation Of Aerobic Granular Sludge, Tyler A. Brickles

Civil & Environmental Engineering Theses & Dissertations

Aerobic granular sludge (AGS) has shown much promise in the advancement of the wastewater treatment industry. AGS has been studied intensely since the early 1990’s due to highly desirable characteristics of nutrient removal efficiency, low footprint, and abnormally faster settling rates than conventional activated sludge. With the exception of a few on-going research projects, all AGS systems have been studied and implemented through the use of sequencing batch reactors (SBR). Recently, a novel approach to developing AGS and improving settling characteristics of activated sludge within conventional activated sludge (CAS) processes has being attempted through the use of external selection.

Predictive Value Of Adhd Symptomatology On Motives And Outcomes Of Stimulant Misuse, Alexander Laszlo Peterkin

Psychology Theses & Dissertations

ADHD stimulant misuse is defined as taking a stimulant used to treat ADHD either without having a prescription for that stimulant or in a manner that deviates from the prescription’s instructions. This has been a growing trend among undergraduate students over recent years. Prior research has found that misusers are likely to have severe symptoms of ADHD, misuse for primarily academic reasons, and display problems associated with substance abuse. The current study aimed to determine the predictive value of ADHD symptomatology on frequency of ADHD stimulant misuse, mediated by academic motives for misuse and substance abuse problems. The survey for …

A Partitioned Approach For Computing Fluid-Structure Interaction, With Application To Tumor Modeling And Simulation, Asim Timalsina

Modeling and Simulation plays a critical role in understanding complex physical and biological phenomena as it provides an efficient and controlled test environment, without the risk of costly experiments and clinical trials. In this dissertation, we present an extensive study of two such systems with integrated application: Fluid structure interaction (FSI) and virotherapy on tumor. Moreover, we substantiate a few preliminary results of FSI application on tumor.

The FSI problem comprises of fluid forces exerted on the solid body and the motion of the structure affecting the fluid flow. FSI problems are of great interest to applied industries, however they …

Two Essays On Forced Ceo Turnover During Envy Merger Waves, And Dividends, Bader Almuhtadi

Finance Theses & Dissertations

Scholars have provided different theories that aim to explain merger waves throughout the years. However, a recent stream of the finance literature addresses the behavioral aspect behind mergers waves and imply that envy motivated CEOs tend to create merger waves. On the other hand, the decision to oust a CEO is considered one of the most important corporate decisions made in the lifetime of corporations. In Essay 1, we participate into the study stream by focusing on whether the incident of forced CEO turnover is higher during the late stages of merger waves where envy turns out to be more …

The Effect Of Bone And Ligament Morphology Of Ankle Joint Loading In The Neutral Position, Jinhyuk Kim

Mechanical & Aerospace Engineering Theses & Dissertations

Computational modeling of joints is used to investigate the effect of injuries, to plan surgeries, and to answer questions about joints that cannot be answered experimentally. Existing models of the ankle joint are moving toward being able to model specific patients, however, they do not include all of the anatomy (e.g., bones and/or ligaments) and have restrictive boundary conditions. These simplification in anatomy are made to minimize pre-processing and computation time. Because biomechanical modeling is increasingly focused on the implementation of patient specific cases, the effects of including more anatomical structures and determining how they affect the model results is …

Hip Mechanics Of Unilateral Drop Landings, Bobbie S. Irmischer

Human Movement Studies & Special Education Theses & Dissertations

Increased hip forces are a proposed factor for osteoarthritis and femoroacetabular impingement. These forces can be estimated through musculoskeletal modeling using measured kinematics and kinetics. An understanding of hip joint loading during landing in a asymptomatic population will begin to elucidate what, if any, sex differences exist and how changes in landing condition alter hip mechanics. The overall purpose of this dissertation was to explore how sex and landing condition effect landing mechanics. Landing mechanics were quantified using ground reaction forces (GRF), hip joint forces (HJF), and lower extremity kinematics during unilateral drop landings from 30-cm, 40-cm, and 50-cm, as …

Current efforts to reduce the global burden of malaria are threatened by the rapid spread throughout Asia of Plasmodium falciparum resistance to artemisinin-based combination therapies, which includes increasing rates of clinical failure with dihydroartemisinin plus piperaquine (PPQ) in Cambodia. Using zinc finger nuclease-based gene editing, we report that addition of the C101F mutation to the chloroquine (CQ) resistance-conferring PfCRT Dd2 isoform common to Asia can confer PPQ resistance to cultured parasites. Resistance was demonstrated as significantly higher PPQ concentrations causing 90% inhibition of parasite growth (IC₉₀) or 50% parasite killing (50% lethal dose [LD₅₀]). This mutation …

Link Between Local Phenology And Climate Change, Blake Steiner, Tatyana Lobova

Virginias Collegiate Honors Council Conference

The SouthEast Virginia Phenology Project was initiated as collaboration between Norfolk Botanical Garden and Old Dominion University in 2010 to document phenology of seven native plants and potential effects of the climate change on their life cycle. The air temperature in Norfolk has increased on average by 0.02ºC per year since 1980. Four out of seven of taxonomically diverse plant species (Mayapple, Flowering Dogwood, Highbush Blueberry, and Common ButtonBush) exhibited significant sensitivity to warming temperatures. Of these four, only Common Buttonbush (Cephalanthus occidentalis) had shown significant phenophases shift. Specifically, first flowering and first fruiting dates had shifted 2.7 …

Granting Personhood For Sentient Non-Human Animals And Sentient Artificial Intelligences: A Demonstrative Argument, Jeremiah Meadows

Virginias Collegiate Honors Council Conference

While the subject of personhood has been exhaustively debated regarding the unborn, personhood for sentient animals and artificial intelligences is a concept that is rarely deliberated. Humanity has learned that there are multiple animal species which are very similar to humans in their self-awareness, emotional capacity, and free will. These traits have been partially developed for artificial intelligences as well, and those characteristics will evolve alongside human and technological development. As stratified societies emerged, there have been multiple occurrences where individuals were deemed lesser but then later acquired equal standing. Dr. Daniel Wilson, roboticist, wrote in his novel Robopocalypse, “It …

The Use Of Rhyme, Rhythm, And Melody As A Form Of Repetition Priming To Aid In Encoding, Storage, And Retrieval Of Semantic Memories In Alzheimer’S Patients, Faiz Plastikwala

Virginias Collegiate Honors Council Conference

Treating Alzheimer’s disease, especially through non-pharmaceutical means, has become increasingly important over the past few decades. I examined the use of melody, rhyme, and rhythm as encoding mechanisms to aid in the retrieval of long term semantic information by juxtaposing previous experiments in the field. Melody, rhyme, and rhythm provide an organizational structure to facilitate the encoding of information. Specifically, chunking, the grouping of smaller units into larger ‘chunks’, helps facilitate long term encoding in patients, and is the byproduct of the organizational structure of a text. A major drawback of using these devices is the loss in the depth …

Testing Effectiveness Of Aqueous Phases From Struvite And Hydroxyapatite Mineral Precipitation As Algal Nutrient Sources, Aaron Lyons

Virginias Collegiate Honors Council Conference

As interest in algal biofuel grows, the need to explore diverse nutrient sources for growing algae becomes apparent. Struvite and Hydroxyapatite (HAP) were precipitated after flash hydrolysis. The leftover aqueous phase (AP) could serve as nutrients source for algae cultivation and the potential reuse of this waste stream is promising. To test this, 12 bottles of Scenedemus sp., four of Struvite, four of HAP, and four control AM-14 synthetic media were cultivated. 10% of the Phosphorus in the synthetic media was replaced with phosphorous from the struvite AP, and 10% of the nitrogen in the synthetic media was replaced …

Depression In Low-Income Adolescents: Guidelines For School-Based Depression Intervention Programs, Gopika Hari

Virginias Collegiate Honors Council Conference

Studies reveal that low income is a significant risk factor for depression and only roughly 25% of children with mental illnesses receive adequate help, the majority of which comes from schools. This study establishes guidelines for depression intervention programs in low-income high schools through a literature review of current practices. This study found that a multi-layered approach with screening, universal education, and high-risk intervention is most effective. Screening should be conducted with a modified PHQ-a test and timely clinical interviews by school psychologists. All students and teachers should receive universal depression education curriculum consisting of principles like depression literacy and …

Bioelectrics Publications

Ebola virus (EBOV) is an extremely contagious pathogen and causes lethal hemorrhagic fever disease in man and animals. The recently occurred Ebola virus disease (EVD) outbreaks in the West African countries have categorized it as an international health concern. For the virus maintenance and transmission, the non-human primates and reservoir hosts like fruit bats have played a vital role. For curbing the disease timely, we need effective therapeutics/prophylactics, however, in the absence of any approved vaccine, timely diagnosis and monitoring of EBOV remains of utmost importance. The technologically advanced vaccines like a viral-vectored vaccine, DNA vaccine and virus-like particles are …

Sense Of Belonging, Emotion Regulation, Perceived Social Support And Mental Health Among College Students, Sara Bock Davis

Psychology Theses & Dissertations

Perceived social support (PSS) is linked to a range of beneficial effects, but the factors that influence the effectiveness of PSS are less well understood. In their Relational Regulation Theory (RRT), Lakey and Orehek (2011) emphasize the importance of distinguishing the role of individual factors from relational influences on PSS. This study tested the RRT by examining whether the association of PSS to three mental health outcomes (i.e., aggression, binge eating, depressive symptoms) varies by two individual factors: sense of belonging and emotion regulation. With a non-clinical college sample, a series of hierarchical regressions tested whether sense of belonging and …
