Unraveling The Molecular Mechanism Of Human Polynucleotide Phosphorylase (Hpnpase) In Controlling Oxidized Rna, Sulochan Malla

Electronic Theses and Dissertations 2010 - 2019

Oxidation by reactive oxygen species is the major source of RNA damaging insult in living organisms. Increased RNA oxidation has been strongly implicated in a wide range of human diseases; predominantly neurodegeneration. Oxidized RNA should be removed from the cellular system to prevent their deleterious effect to the cells and organisms. In eukaryotic cells, mitochondria are the major intracellular sources of ROS and may cause greater damage to the mitochondrial RNA. In this study, we first investigated the RNA oxidation, by measuring the level of 8-hydroxy-Guanosine (8-oxo-Guo), inside mitochondria and cytoplasm in cultured human cells. We discovered that the mitochondrial …

Up, Down, And All-Around: The Swirling-Transfer Student Athlete Experience At Athletic State University, Ethan C. Swingle

Electronic Theses and Dissertations 2010 - 2019

Intercollegiate athletics have become an integral part of campus life (Shulman & Bowen, 2001), and have grown exponentially in the resources universities put forth to participate in this extracurricular activity (Clotfelter, 2011). One of the biggest evolutions of intercollegiate athletics has been student athlete transfer (Cooper & Hawkins, 2014); however, little research has been conducted on the transfer student athlete, or the transfer student athlete experience (Cooper & Hawkins, 2014). As such, the purpose of this instrumental case study (Stake, 1995) was to discover and describe the experiences and perceptions of swirling-transfer student athletes at Athletic State University. A purposive …

Veins Of Oppression In Under The Feet Of Jesus, Cynthia Wedding

Electronic Theses and Dissertations 2010 - 2019

“Veins of Oppression” takes an interdisciplinary approach towards unearthing the layers of subjugation piled on Chicano/a/x migrant farm workers in the fields of California, visible in Helena Maria Viramontes’ Under the Feet of Jesus. While critics such as Christa Grewe-Volpp, Anne Shea, and Sarah Wald have produced progressive work about this text that adds to their respective disciplinary fields, unique to this collection, the interdisciplinary framework visible in “Veins of Oppression” forces readers to bear witness to the many ways Chicano/a/x migrant farm workers are kept from accessing the privileges implicit in U.S. citizenship through longstanding and current agricultural practices. …

Using Hydrogeophysical Methods For Investigating Carbon Dynamics In The Greater Everglades Watershed: Implications For The Spatial And Temporal Variability In Carbon Stocks And Biogenic Gas Fluxes, Matthew D. Mcclellan

Electronic Theses and Dissertations 2010 - 2019

Peat soils store a large fraction of the global soil carbon (C) pool and comprise 95% of wetland C stocks. They also have the capability to produce and release significant amounts of greenhouse gasses (CO2, CH4) into the atmosphere. Most studies of wetland soil C and gas flux dynamics have been done in expansive peatlands in northern boreal and subarctic biomes. However, wetlands in temperate and tropical climates are vastly understudied despite accounting for more than 20% of the global peatland C stock and storing large amounts of biogenic gasses Although studies investigating greenhouse gas dynamics from peatlands have increased …

Utilizing Remote Sensing To Describe The Area Of Occurrence Of The Dania Beach Monkeys, Chlorocebus Sabaeus, From Introduction To Present, Ashley M. Lyon

Electronic Theses and Dissertations 2010 - 2019

This research investigates land use change and the area of occurrence of an introduced primate species, Chlorocebus sabaeus, from 1940 until the present. Research into the importation and subsequent release of these monkeys has revealed that they were released from a failed tourist attraction in 1947. The attraction was located southeast of the Hollywood International Airport in Fort Lauderdale, Florida. Remote sensing techniques were utilized to examine land use change over time, create a land classification map, and create a canopy model. These data were used to better understand the area of occurrence of an introduced primate species by examining …

Electronic Theses and Dissertations 2010 - 2019

This study offers a better understanding of the reasons why parents from six different countries across the Western hemisphere chose private, non-denominational schools for their children’s education. The findings deepen the knowledge in what is currently an underdeveloped field of research in education. The overarching research question was: What are the primary reasons why parents chose a private nondenominational school in Mexico, Spain, Costa Rica, United States, United Kingdom, and South Africa for their children’s education? To explore this question in depth, the researcher considered five sub-questions and employed a grounded theory qualitative research design. Data were collected twofold through …

Yesterday Will Come, Meryl D'Sa

Electronic Theses and Dissertations 2010 - 2019

Yesterday Will Come is a hybrid collection of linked short stories that focuses on the way a particular family passes down the family history through physical and emotional memories. The collection largely focuses on the process of making and preserving memories and how the lack of control over one’s memory can lead to paranoia and displacement in their life. Particular value is attached to certain memories and the value and emotion attached can at times overwrite the actual content of the memory. The stories center around the Riviera family and particularly Ana Riviera’s life as she considers the many aspects …

New Perspectives On The Schrödinger-Pauli Theory Of Electrons: Part I, Viraht Sahni

Publications and Research

Schrödinger-Pauli (SP) theory is a description of electrons in the presence of a static electromagnetic field in which the interaction of the magnetic field with both the orbital and spin moments is explicitly considered. The theory is described from the new perspective of the individual electron via its equation of motion or ‘Quantal Newtonian’ first law. The law is in terms of ‘classical’ fields whose sources are quantum mechanical expectation values of Hermitian operators taken with respect to the system wave function. The law states that each electron experiences an external and an internal field, the sum of which vanish. …

Inquiry Into The Correlation Between Burnout And Depression, Irvin Sam Schonfeld, Jay Verkuilen, Renzo Bianchi

Publications and Research

The extent to which burnout refers to anything other than a depressive condition remains an object of controversy among occupational health specialists. In three studies conducted in two different countries and two different languages, we investigated the discriminant validity of burnout scales by evaluating the magnitude of the correlation between (latent) burnout and (latent) depression. In Study 1 (N = 911), burnout was assessed with the Maslach Burnout Inventory–General Survey’s Exhaustion subscale and depression with the depression module of the Patient Health Questionnaire (PHQ). In Study 2 (N = 1,386), the Shirom–Melamed Burnout Measure was used to assess burnout and …

Technological Encounters In The Interculturality Of Istanbul's Recording Studios, Eliot Bates

Publications and Research

This essay questions what is cultural within a recording studio, and the extent to which interculturality could be a useful lens for examining studio encounters and by extension other forms of artistic-technological labor. As I will show, when the concept of interculturality surfaces it rarely is accompanied by a sufficiently nuanced concept of "culture", and additionally relies upon an assumption that the "inter-" is mapping an encounter between individuals representing discrete cultural units, typically defined in reductive demographic terms. Interculturality may be able to be partly recuperated, however, through a more flexible and realistic conceptualization of culture that is more …

Patients’ Experiences On Accessing Health Care Services For Management Of Hypertension In Rural Bangladesh, Pakistan And Sri Lanka: A Qualitative Study, Helena Legido Quigley, Aliya Naheed, H. Asita De Silva, Imtiaz Jehan, Z Samad

Hypertension is the leading risk factor for cardiovascular disease and leading cause of premature death globally. In 2008, approximately 40% of adults were diagnosed with hypertension, with more than 1.5 billion people estimated to be affected globally by 2025. Hypertensiondisproportionally affects low- and middle-income countries, where the prevalence is higher and where the health systems are more fragile. This qualitative study explored patients' experiences on the management and control of hypertension in rural Bangladesh, Sri Lanka and Pakistan. We conducted sixty semi-structured interviews, with 20 participants in each country. Hypertensive individuals were recruited based on age, gender and hypertensive status. …

Large Pelvic Tubercle In Orangutans Relates To The Adductor Longus Muscle, Brian M. Shearer, Magdalena Muchlinski, Ashley S. Hammond

Publications and Research

Orangutan pelves commonly exhibit a large, projecting tubercle in the iliopubic region, historically assumed to homologous to the pubic tubercle in humans. However, it is not clear whether this tubercle is a unique feature of Pongo, or if it is anatomically homologous with the human pubic tubercle when considered as a soft tissue attachment point. To clarify this issue, we dissected orangutan and other ape cadaveric specimens to evaluate the pelvic brim soft tissues and how they may relate to the tubercle (when present). We additionally conducted a broad osteological survey of pelvic brim morphology across 28 primate genera …

Isolation Of Rabies Virus From The Salivary Glands Of Wild And Domestic Carnivores During A Skunk Rabies Epizootic, Cornell University Jimenez, Terry R. Spraker, Jessica Anderson, Richard Bowen, Amy Gilbert

United States Department of Agriculture Wildlife Services: Staff Publications

Rabies is a fatal zoonotic disease of global importance. Rabies virus is shed in the saliva of infected hosts and is primarily transmitted through bite contact. Canine rabies has been eliminated from the US, but wildlife constitutes more than 90% of the reported cases of animal rabies in the US each year. In the US, several wild carnivore species are reservoirs of distinct variants of rabies virus (RV). After decades of apparent absence, the south-central skunk (SCSK) RV variant was detected in Colorado in 2007 and resulted in a large-scale epizootic in striped skunk (Mephitis mephitis) populations in northern Colorado …

Technical Standards Meet Administrative Law: A Teaching Guide On Incorporation By Reference, Emily S. Bremer

Journal Articles

When an agency incorporates by reference, it promulgates a rule that identifies—but does not reprint—material already published elsewhere. The incorporated materials thus become binding law without actually being printed in the agency's regulations. Sometimes the incorporated materials are privately developed technical standards, which are often copyrighted and available only for a fee. This restriction on access undermines transparency and public participation in the rulemaking process. Finding a solution is challenging because the problem is multidimensional, implicating public policy in the areas of administrative law, federal standards law and policy, and copyright.

This teaching guide is part of module that offers …

Experimental Infections Of Norway Rats With Avian‑Derived Low‑Pathogenic Influenza A Viruses, Kaci K. Vandalen, Nicole M. Nemeth, Nicholas O. Thomas, Nicole L. Barrett, Jeremy W. Ellis, Heather J. Sullivan, Alan B. Franklin, Susan A. Shriner

United States Department of Agriculture Wildlife Services: Staff Publications

Influenza A viruses (IAVs) are a public-health, veterinary, and agricultural concern. Although wild birds are considered the primary reservoir hosts for most IAVs, wild-bird IAV strains are known to spill over into poultry, domestic or wild mammals, and humans. Occasionally, spillover events may result in adaptation or reassortment with other strains. Moreover, some IAV strains found in wild waterfowl mutate into highly pathogenic forms in poultry, causing tremendous economic losses. When domestic animals, wildlife, and humans dwell in close proximity to each other, such as may be the case with agricultural operations, wildlife may represent a potential risk for interspecies …

Predation And Disease-Related Economic Impacts Of Wild Pigs On Livestock Producers In 13 States, Aaron M. Anderson, Chris Slootmaker, Erin Harper, Ryan S. Miller, Stephanie A. Shwiff

United States Department of Agriculture Wildlife Services: Staff Publications

We report the results of a survey on wild pigs (Sus scrofa) damage to livestock producers in 13 US states (Alabama, Arkansas, California, Florida, Georgia, Louisiana, Mississippi, Missouri, North Carolina, Oklahoma, South Carolina, Tennessee, Texas). The survey was distributed by the USDA National Agricultural Statistical Service in the summer of 2017 to a sample of livestock producers in the 13-state region. Findings indicate that predation and disease-related damage can be substantial in certain states and for certain types of livestock. In particular, damage to cattle operations in Texas and Arkansas was substantially higher than damage in other states …

Potential Role Of Wildlife In The Usa In The Event Of A Foot-And-Mouth Disease Virus Incursion, Vienna R. Brown, Sarah N. Bevins

United States Department of Agriculture Wildlife Services: Staff Publications

Foot-and-mouth disease (FMD) is caused by foot-and-mouth disease virus (FMDV) which affects domestic and wild cloven-hoofed species. The FMD-free status of the USA and the tremendous economic impact of a virus incursion motivated the development of this evaluation of the potential role of wildlife in the event of a virus introduction. Additionally, this manuscript contains a summary of US vulnerabilities for viral incursion and persistence which focuses specifically on the possible role of wildlife. The legal movement of susceptible live animals, animal products, by-products and animal feed containing animal products pose a risk of virus introduction and spread. Additionally, the …

Reducing Prairie Dog Populations And Damage By Castration Of Dominant Males, Gary W. Witmer

United States Department of Agriculture Wildlife Services: Staff Publications

Black-tailed prairie dogs (Cynomys ludovicianus) occur widely across the prairie states of North America. They compete with livestock for forage, transmit plague, and damage lawns, landscaping, and property. Interest in non-lethal methods, such as immunocontraception, is growing; however, reductions in the population due to contraception may be offset by increases in survival because adults and yearlings are not subject to the energetic demands of reproduction, and lower densities may increase the amount of resources available to growing offspring. Surgical sterilization provides a means for modeling these effects. Thus, we castrated males prior to the 1998 breeding season to simulate the …

Religion, Child Custody, And Visitation, Margaret F. Brinig

Journal Articles

Folk wisdom has it that the family that prays together stays together. Empirical studies bear this out—couples who share an intensity of religious faith, even though not necessarily of the same faith tradition, do tend to marry in the first place rather than cohabit, have more stable marriages, have children, stay together longer even in troubled relationships, and be more likely to wait for divorce until any children are adults.

Despite this rosy picture, some religious couples do divorce, and these breakups are more fault-driven and acrimonious, even with no-fault divorce available, than those of their nonreligious peers. That is, …

A Mindfulness Meditation Intervention To Decrease Stress, Anxiety, And Depression Among Medical And Premedical Students, Bridget Statler Smith

Electronic Theses and Dissertations 2010 - 2019

The challenges inherent in pursuing a medical education can leave many students at risk of experiencing stress and burnout. Premedical and medical students have been found to experience high levels of stress, anxiety, and depression (Fang et al., 2010; Niemi & Vainiomaki, 2006; Vitaliano, Russo, Carr, & Heerwagen, 1984). The sources of stress for premedical and medical students include academic obligations, the financial burden of paying for medical school, and family relationships. If excessive stress is left untreated it can result in negative health risks such as depression, anxiety, suicide ideation, and other physiological distress disorders. There are proven ways …

3d-Printed Flexible Polylactic Acid/ Thermoplatic Polyurethane (Pla/Tpu) Stents For Esophageal Malignancies, Maohua Lin

Electronic Theses and Dissertations 2010 - 2019

Palliation therapy for dysphagia using esophageal stents is the current treatment of choice for those patients with inoperable esophageal malignancies. However, the stents currently used in the clinical setting, regardless of the type of metal mesh or plastic mesh stents (covered/uncovered), may cause complications, such as tumor ingrowth and stent migration into the stomach. Furthermore, metal mesh stents have limited capacities for loading anti-cancer drugs. To effectively reduce/overcome those complications and enhance the efficacy of drug release, we designed and 3D-printed a tubular, flexible polymer stent with spirals, and then load anti-cancer drug, paclitaxel, on the stent for drug release. …

A Novel Solar Thermal Membrane Distillation System For Drinking Water Production In Undeveloped Areas, Rahamat Ullah Tanvir

Electronic Theses and Dissertations 2010 - 2019

In this research, a heat localizing solar thermal membrane distillation system has been developed for producing potable water from untreated surface water, wastewater, and seawater, using solely solar thermal energy. Unlike most other membrane technologies, this system requires no electrical power or equipment for its operation. The high production rate was achieved through the effective evaporation of water molecules within the pores of the membrane without dissipating much heat to the bulk feed water. It can remove suspending particles, microorganisms, inorganic salts, as well as organic contaminants from the feed water. The system can produce potable water for 32, 18, …

A Gpu- Based Simulated Annealing Algorithm For Intensity-Modulated Radiation Therapy, Panagiota Galanakou

Electronic Theses and Dissertations 2010 - 2019

Simulating Annealing Algorithm (SAA) has been proposed for optimization of the Intensity-Modulated Radiation Therapy (IMRT). Despite the advantage of the SAA to be a global optimizer, the SAA optimization of IMRT is an extensive computational task due to the large scale of the optimization variables, and therefore it requires significant computational resources. In this research we introduce a parallel graphics processing unit (GPU)-based SAA developed in MATLAB platform and compliant with the computational environment for radiotherapy research (CERR) for IMRT treatment planning in order elucidate the performance improvement of the SAA in IMRT optimization. First, we identify the “bottlenecks” of …

A Quantitative Analysis Of Ceramic Distribution In The East Okeechobee Area, Stefanie D’Erasmo

Electronic Theses and Dissertations 2010 - 2019

The East Okeechobee area is situated along the southeast coast of Florida, throughout Palm Beach and Martin Counties, and has proved difficult to access in a broad archaeological context. This is due to the blending of cultural characteristics from the surrounding areas and due to the suspected transitional nature of this region. To gain a better understanding of the cultural composition and interrelations of the East Okeechobee Area, this analysis statistically models, both synchronically and diachronically, the frequencies of ceramic types from multiple archaeological sites in and around this region.

Acute Response Of Neuroprotective Associated Biomarkers To Various Compound Resistance Exercises In Well-Trained Men, Trevor K. Johnson

Electronic Theses and Dissertations 2010 - 2019

This study examined if multi-joint resistance exercises could elicit expression of biomarkers associated with neuroprotection. Thirteen well-trained males performed 4 sets to failure at 80% of a one-repetition maximum (1RM) on the back squat, bench press, and deadlift. The biomarkers measured immediately pre- and post-exercise were brain derived neurotrophic factor (BDNF), insulin-like growth factor 1 (IGF-1), cathepsin B (CatB), and interleukin 6 (IL-6). There was a main time effect (p<0.01) for BDNF with significant increases in the deadlift (p=0.01) and bench press (p=0.01) conditions, but not the squat (p=0.21). There was a main time effect (p<0.01) for IL-6 with a significant increase in the squat (p<0.01). There was no significant increase in CatB or IGF-1 (p>0.05). Additionally, there was no significant relationship between BDNF and IL-6 response.
