An In Vivo Evaluation Of Pulmonary Immune Response And Toxicity Following Combined Respiratory Exposure To Crystalline Silica And Diesel Particulate Matter, Breanne Yingling Farris
Graduate Theses, Dissertations, and Problem Reports (ETD)
Crystalline silica (SIL) and diesel particulate matter (DPM) are each well-recognized for their potential to cause pulmonary toxicity following inhalation. However, these particulates have also been identified as coexisting in mixtures of respirable aerosols at a variety of industrial settings: mining, oil and gas extraction, construction, road construction, tunneling, excavation, foundry, and sandblasting. In order to characterize the potential for increased pulmonary health effects when these particulates are inhaled in a mixture, a battery of acute and subacute in vivo exposure studies were conducted. The current studies examined co-exposure to SIL and DPM at doses that were derived from field …
Black-Legged Tick Distributions, Small Mammal Abundances, Mast Production, And Vegetative Influences On Lyme Disease Apparent Prevalence On Fort Drum Military Installation, New York, Samantha R. Fino
Graduate Theses, Dissertations, and Problem Reports (ETD)
Lyme disease is the most common infectious disease spread by black-legged ticks in the Northern Hemisphere. Lyme disease is a vector-borne zoonotic disease typically caused by bacterial spirochetes of the species Borrelia burgdorferi. The primary vector of Lyme disease in the Midwestern and eastern United States is Ixodes scapularis, the deer or black-legged tick. Although there are several preventative measures against ticks that carry Lyme disease, such as public education regarding personal protection (e.g., wearing light colored clothing, tucking pants into socks, wearing repellent, promptly inspecting oneself to remove ticks, getting pets vaccinated) and recommended control measures, it is important …

Spread Of False News Stories On Facebook: An Assessment Of Credibility Cues And Personality, Lacie Geary
Graduate Theses, Dissertations, and Problem Reports (ETD)
This study used a 2 x 2 method to examine the effectiveness of credibility cues on Facebook and how the personality traits neuroticism and openness impact sharing behaviors across cues of different shapes and colors. Findings suggested the color red increased cue noticeability, however, overall a low number of participants noticed any of the four varying cues across conditions, indicating that the fast-paced scrolling nature of online mediums prevents users from noticing credibility cues. Future research should examine the differences in pace of scrolling and information intake across different generations. This information might be useful to media outlets to help …
Bobcat Population Ecology In West Virginia, Stephanie Michelle Landry
Bobcat Population Ecology In West Virginia, Stephanie Michelle Landry
Graduate Theses, Dissertations, and Problem Reports (ETD)
Bobcats (Lynx rufus) are a popular furbearer and game species throughout their range in North America, where they serve as a top predator in many of their ecosystems. However, bobcat populations across their range declined during the 1800s and early 1900s due to overharvest. Overharvest and habitat loss in Europe also affected the Iberian lynx ( L. pardinus), resulting in the listing of all Lynx spp. under the Convention on International Trade in Endangered Species in 1977. Bobcats were listed under Appendix II, which required that state management agencies monitor their bobcat populations for stability. Since their listing, bobcat populations …

Philosophical Approaches To Compositional Technique In Isang Yun's Works For Solo Flute, Mirim Lee
Graduate Theses, Dissertations, and Problem Reports (ETD)
As modern composers draw on an ever-widening source of inspiration from musical traditions and practices around the world, the music of twentieth-century Korean composers deserves greater recognition and increased performance within Western culture. This is especially true of the works of Korean-German composer Isang Yun (1917-1995), a prolific composer whose output is largely unknown in Korea. This research paper will examines selected works for solo flute by Yun with particular attention to Sori (1988).;Isang Yun studied composition under Tony Aubin (1907-1981) and Pierre Revel (1901-1984) at the Paris Conservatory from 1956-1957. He also studied in West Berlin at the Musikhochschule …
Microbial Quality And Pathogen Decontamination Strategies For Locally-Grown, Fresh Produce From West Virginia And Kentucky, Ka Wang Li
Graduate Theses, Dissertations, and Problem Reports (ETD)
This study aimed to evaluate the microbiological quality/safety of fresh produce from farmers' markets (FM) and assess the post-harvest washing practice with antimicrobials to inactivate Salmonella and Listeria monocytogenes on fresh produce. In study I, 212 produce samples were tested for the presence of Salmonella and Listeria spp. using modified FDA-BAM methods. Aerobic plate counts (APCs), total coliforms (TCCs), and yeast/molds were analyzed on petri-films. Among the 212 samples, the APCs, TCCs, and yeast/molds were 3.72-5.63, 3.67-5.47, and 3.07-4.13 log CFU/g, respectively, with spinach containing the highest (P<0.05) populations. Among all tested samples, Salmonella enterica spp. enterica was detected on 18.6% of spinach, 10.9% of tomatoes, 18.5% of peppers, and 56.3% of cantaloupes, which is much higher than previous reported. Only 3.78% of the samples were confirmed for Listeria spp., and 50% of them were identified as L. monocytogenes, based on multiplex PCR results. Due to the high percentage of pathogens detected on the farmers' marker produce, an evaluation of post-harvest produce washing with various antimicrobials was conducted in study II. Specifically, spinach, tomatoes, green peppers and cucumbers were inoculated with S. Typhimurium and Tennessee or L. monocytogenes and washed in tap water, vinegar water (10%), lactic acid (5%), a lactic and citric acid blend (2.5%), and sodium hypochlorite (200 ppm) for 30 sec or unwashed. Vinegar water (10%) showed better (P<0.05) reduction of S. Typhimurium and Tennessee on tomatoes and cucumbers, and L. monocytogenes on tomatoes and peppers than tap water. The three antimicrobials reached an additional reduction level of 0.9 to 2.7 (S. Typhimurium and Tennessee) and 0.2 to 1.4 log CFU/g ( L. monocytogenes) compared to tap water. Lactic acid caused the greatest (P<0.05) reduction of S. Typhimurium and Tennessee on spinach and green peppers, and sodium hypochlorite showed the great (P<0.05) reduction of L. monocytogenes on cucumbers. The results supplied important information for FM vendors to develop post-harvest protocols to control foodborne pathogens.

The Use Of Concentration Of Anti-Mullerian Hormone (Amh) As An Indicator Of Reproductive Performance In Livestock Species, Adam Karl Russell Redhead
The Use Of Concentration Of Anti-Mullerian Hormone (Amh) As An Indicator Of Reproductive Performance In Livestock Species, Adam Karl Russell Redhead
Graduate Theses, Dissertations, and Problem Reports (ETD)
Reproductive success is essential for high levels of animal productivity. Low fertility has been identified as one of the main constraints hindering the productivity of livestock systems. To address this problem, several tools such as genomic selection and assisted reproductive techniques (ART) have been implemented. Two of the more common ART used to improve reproductive performance are artificial insemination (AI) and embryo transfer (ET). The success of these methods is highly dependent on individual animal characteristics; therefore the ability to select animals that provide high levels of reproductive success is essential. The size of the ovarian antral follicular population (AFP) …

The Potential Impact Of Art Therapy Approaches In An Alternative Learning School Setting In Urban West Virginia, Brianna Saddler
Graduate Theses, Dissertations, and Problem Reports (ETD)
Now more than ever American adolescents are suffering from severe anxiety (Lewis, 2017). In the past, over-achieving students were those parents least worried about when it came to experiencing anxiety but now studies show these students are just as likely to experience anxiety as those learners considered to be underachievers. The purpose of this paper is to inform the reader how art therapy approaches embedded into daily lesson plans could be used in alternative learning school settings to help students deal with anxiety. Through my own experiences as a practicing art teacher in both general education art classrooms and alternative …
A Conductor's Perspective On Stravinsky's "Danse Sacrale" From "Le Sacre Du Printemps": Evaluation Of Revisions, Analysis And Considerations For Conducting, Hanjin Sa
Graduate Theses, Dissertations, and Problem Reports (ETD)
The final dance, Danse sacrale from the ballet Le Sacre du printemps by Igor Stravinsky (1882-1971) presents various challenges for conductors: both textual and technical. For the textual challenges, this research paper focuses on the comparative studies of various revisions, the early sketchbook, and the autograph full score. The study of correspondence between Stravinsky and the early conductors of Le Sacre (Pierre Monteux and Ernest Ansermet) also offers important clues for solving the puzzle with which Stravinsky himself had struggled for decades.;Both the 1943-revised version and Nicholas Slonimsky's re-barring of the Danse sacrale will be closely examined. Despite Stravinsky's wish …

Graduate Theses, Dissertations, and Problem Reports (ETD)
This thesis is a study of Sir Frederick Jackson, an early British explorer and administrator between 1880 and 1917 focusing on three main facets of his career those being his early days as an explorer, his administration in Kenya, and then his governorship of Uganda. Within these three main focal points, various important historical topics such as the Uganda Railway, the Maasai Move, and the planter and peasant dilemma in Uganda are discussed in relation to Jackson's position at that moment of his career in order to shed some light on Jackson and the early colonial period in Africa.
Characterizing The Mechanisms Of Insulin Resistance In Dairy Cattle, Amanda Nicole Davis
Characterizing The Mechanisms Of Insulin Resistance In Dairy Cattle, Amanda Nicole Davis
Graduate Theses, Dissertations, and Problem Reports (ETD)
Dairy cows transitioning from gestation to lactation experience insulin resistance as maternal adaptation to partition nutrients toward the mammary gland to support milk production. Insulin resistance causes increased lipolysis and free fatty acid (FFA) release into circulation. Unfortunately, this metabolic adaptation occurs during a time when energy demands are heightened and cows are already experiencing negative energy balance. As a result, accelerated hepatic FFA influx promotes hepatic triacylglycerol (TAG) accumulation and ketogenesis, which can cause postpartum metabolic disease. In diabetic monogastrics, mechanisms that mediate insulin resistance involve the sphingolipid ceramide. The role of ceramide in insulin signaling in dairy cows …
An Evaluation Of The Effects Of Treatment Integrity Errors On Skill Acquisition During Discrete-Trial Instruction, Jennifer M. Owsiany
An Evaluation Of The Effects Of Treatment Integrity Errors On Skill Acquisition During Discrete-Trial Instruction, Jennifer M. Owsiany
Graduate Theses, Dissertations, and Problem Reports (ETD)
Previous research has demonstrated that delivering controlling prompts and reinforcers with low-levels of treatment integrity may interfere with the acquisition of skills during discrete-trial instruction. However, implementing certain components of discrete-trial instruction with varying levels of low integrity may influence skill acquisition differently. In Experiment 1, we evaluated the effects of delivering a prompt following participants' incorrect responses with 25%, 50%, 75%, and 100% integrity on skill acquisition with two children with autism spectrum disorder. In Experiment 2, we evaluated the effects of delivering a reinforcer following participants' correct responses with 25%, 50%, 75%, and 100% integrity on skill acquisition …
Fear Of Pain And Dental Care-Related Fear: Associations With The Mc1r Gene, Cameron L. Randall
Fear Of Pain And Dental Care-Related Fear: Associations With The Mc1r Gene, Cameron L. Randall
Graduate Theses, Dissertations, and Problem Reports (ETD)
Fear of pain is experienced in acute and chronic pain populations, as well as generally, and impacts numerous aspects of the pain experience, including pain intensity, pain-related disability, and pain behavior (e.g., avoidance). A related but separate construct, dental care-related fear, also is experienced in the general population, and impacts dental treatment-seeking behavior and oral and systemic health. Very minimal work has addressed the role of genetics in the etiologies of fear of pain and dental care-related fear. Limited available data suggest that variants of the melanocortin-1 receptor (MC1R) gene may predict greater levels of dental care-related fear. The MC1R …

Implications Of Primary Cilia And Associated Lysophosphatidic Acid Signaling In Glioblastoma Biology And Therapy, Yuriy V. Loskutov
Implications Of Primary Cilia And Associated Lysophosphatidic Acid Signaling In Glioblastoma Biology And Therapy, Yuriy V. Loskutov
Graduate Theses, Dissertations, and Problem Reports (ETD)
The primary cilium is a ubiquitous organelle presented on most human cells. It serves as a crucial signaling hub for multiple pathways including growth factor and G-protein coupled receptors. Loss of primary cilia was observed in various cancers, however, the implications of this event are unclear. Several studies show that loss of cilia promotes cell proliferation, suggesting that alteration of ciliary-dependent signaling can drive the hyperproliferative phenotype of cancer cells, therefore re-establishing primary cilia or targeting altered signaling pathways could be a beneficial strategy as an anti-cancer therapy.;Glioblastoma (GBM) is one of the deadliest cancers with a median survival of …
Where The Earth Breathes Inside: The Attitudes Of Lakota People Toward Wind Cave National Park, Adam Rossi
Where The Earth Breathes Inside: The Attitudes Of Lakota People Toward Wind Cave National Park, Adam Rossi
Graduate Theses, Dissertations, and Problem Reports (ETD)
Wind Cave National Park, located in the Black Hills of South Dakota, has a long and complex history concerning local indigenous peoples, including the Lakotas. Wind Cave is the location of the Lakotas' traditional origin story, and is now protected by a park that represents a federal government that many indigenous peoples of this country view negatively. Despite this, no study has attempted to characterize attitudes of local indigenous people towards the park. Recommendations from an earlier study encourage the park to collaborate closely with local indigenous tribes, and it would be beneficial for the park to have an understanding …

Skeletal Muscle Arteriole Dysfunction And Microvessel Density In Metabolic Syndrome And Depression: How Exercise Can Be Used As An Intervention, Kayla Whitney Branyan
Graduate Theses, Dissertations, and Problem Reports (ETD)
The present study examined the effect of unpredictable chronic mild stress (UCMS) on peripheral microvessel function in healthy and metabolic syndrome (MetS) rodents, and whether exercise training could prevent the vascular dysfunction associated with UCMS. Our initial hypothesis was that: 1) LZRs exposed to UCMS would have peripheral microvascular dysfunction similar to that evident in the OZRs controls due to a reduction in NO bioavailability and an increase in ROS production; 2) the comorbidity between MetS exposed to UCMS will exacerbate the already existing peripheral microvascular dysfunction; 3) exercise could limit the peripheral microvascular dysfunction by decreasing oxidative stress and …
Whole-Farm Phosphorus Management In West Virginia Beef Cattle Operations, Justin Brackenrich
Whole-Farm Phosphorus Management In West Virginia Beef Cattle Operations, Justin Brackenrich
Graduate Theses, Dissertations, and Problem Reports (ETD)
Demand for animal proteins is increasing worldwide, spurring an increase in forage based agricultural production. Forage based agriculture utilizes grass and legume crops from areas which are not suited for row-crop production to feed ruminant animals. These systems provide increased animal proteins to consumer markets, while using minimal amounts of cereal crops that would otherwise be used for human consumption. However, forage based agriculture does not come without a risk of environmental degradation. The US EPA determined that agriculture non-point source (NPS) pollution is among the top three causes of phosphorus (P) related surface water impairment and accounts for an …
Baltimore City Reservoir Watershed Forests Deer Exclosure Study: Deer Impact In An Even-Aged, Second Growth, Hardwood Forest Over A Ten Year Period, Walter Buck
Graduate Theses, Dissertations, and Problem Reports (ETD)
White-tailed deer (Odocoileus virginianus) have the potential to change forest community dynamics by affecting the persistence of individual tree species and altering overstory composition. We evaluated the Baltimore City Reservoir Watershed Forests Deer Exclosure Study for a better understanding of the effects of over-browsing in this hardwood forest. The study examined the effects of deer browsing over a ten year period, using 20 fenced deer exclosure plots (8x8 feet), paired with unfenced reference control plots. Tree seedling and sapling abundance was compared between the fenced deer exclosure plots and the unfenced control plots over the ten year period. Total tree …
