This present study examines the relationships between environmental risk perceptions and pro-environmental attitudes and behaviors within the theory of the risk society. This quantitative study was conducted online, with a sample size of 218 undergraduate college students from James Madison University. Environmental risks were measured at the societal and individual levels, as well as within five separate risk categories. As expected, I found positive relationships between these risks and pro-environmental attitudes and behaviors, however the relationships between individual and societal risk perceptions were different than I anticipated. Where I expected individual risk perceptions to drive both pro-environmental behaviors and attitudes, …
Public Perception On The State Of Air Quality In Malta, Nikolas Cassar
Public Perception On The State Of Air Quality In Malta, Nikolas Cassar
Masters Theses, 2010-2019
Public perception on the state of air quality is an unclear and hazy concept whereby every individual has different opinions and views. In fact, the state of air quality is a major concern in many countries, including in Malta. This problem arises from the emissions of a number of pollutants to the atmosphere from a host of processes such as the combustion of fuel to generate electricity and the internal combustion engines to manoeuvre cars. Amongst these pollutants, there are benzene and nitrogen dioxide, which are very hazardous since they cause problems related to human health and contribute in the …

Hand Hygiene Perceptions Of Student Nurses., Brittany Berger
Hand Hygiene Perceptions Of Student Nurses., Brittany Berger
Undergraduate Honors Theses
Compliance with hand hygiene is widely recognized as the most important factor in preventing transmission of infection to patients in healthcare settings (Haas and Larson, 2007). Hand hygiene dramatically decreases the potential pathogens on hands and is considered the first measure for decreasing the risk of transmitting organisms to patients, healthcare professionals, and family members. Noncompliance with hand hygiene practices has been shown to increase healthcare-associated infections, costing hospitals $35.7-$45 billion each year (Centers for Disease Control and Prevention [CDC], 2012). Education about hand hygiene starts in school and should transfer into the real world of nursing. The purpose of …
Impact Of Oxidative Stress On Female Fertility., Tasha Harris
Impact Of Oxidative Stress On Female Fertility., Tasha Harris
Undergraduate Honors Theses
This study examined nutritional status and fecundity of women and was approved for patient enrollment by the ETSU Institutional Review Board (IRB). Once enrolled, participants filled out two food frequency questionnaires (FFQ, fruit/vegetable intake, fat intake), self-reported anthropometric data, and had one 5 mL vacutainer of whole blood (EDTA) collected for measures of oxidative stress (OS), coenzyme Q10 level, and fatty acid profile of the red blood cell (RBC) membrane. Participants were either designated to the case group (13 women experiencing fertility problems and an anti-mullerian hormone level of 1 ng/ml or less (AMH, <1 ng/mL)) or the control group (13 women experiencing normal ovulation cycles and no evidence of polycystic disease). This study hypothesized that the case group would have poorer plasma antioxidant status, consume more dietary saturated fat and have lower levels of omega-3 and higher levels of omega-6 fatty acids in the RBC membrane. Results showed that case participants had significantly higher body mass index (BMI) when graduating from high school, BMI upon enrollment in the study, and trended to gain more weight since high school. Antioxidant status of the plasma tended to be higher for the case group. This result was surprising as case participants consumed significantly fewer servings of fruits and vegetables (sources of antioxidants) than control subjects. FFQ results indicated that case participants consumed significantly higher amounts of total fat (g), saturated fat (g), unsaturated fat (g), and their diets had a higher dietary fat percent. No significant differences were noted in the individual fatty acids isolated from the RBC membrane or in calculated ratios of fatty acid between case and control groups. The fatty acid profile from RBC membranes are in agreement with self-reported fat intake from FFQ data and may provide a rationale for no differences observed between the two groups.

Effects Of Nurr1 Genotype And Aging On Dopamine Neurotransmission And Behavior, Evangel Kummari
Effects Of Nurr1 Genotype And Aging On Dopamine Neurotransmission And Behavior, Evangel Kummari
Theses and Dissertations
Nurr1 is a transcription factor essential for the establishment, development, terminal differentiation and maintenance of mesencephalic dopamine neurons. Nurr1 is thought to coordinate the expression of dopamine neurotransmission genes. Nurr1-null heterozygous (+/-) mice have reduced Nurr1 function, which impacts dopamine neuron function in a region specific manner. Since aging can affect Nurr1 expression, we hypothesize that aging and +/- genotype will have significant effects on dopamine regulation and dopamine related behaviors. To test this hypothesis, regional neurochemistry and behavioral tests of wild type (+/+) and +/- mice at 3 months of age (young) and 12-16 months of age (aged)was performed. …

Evaluating User Satisfaction And Perceived Quality Of Electronic Health Records In Mississippi, Dakota Chamblee
Evaluating User Satisfaction And Perceived Quality Of Electronic Health Records In Mississippi, Dakota Chamblee
Theses and Dissertations
Electronic Health Records (EHRs) is a health information technology that has already begun to change the way healthcare providers care for patients. EHRs can potentially enhance the quality and efficiency of patient care (Simon et al., 2010); however, some research shows that EHRs do not always do so. The lack of improved efficiency and quality of care can lead to frustrated and dissatisfied users. The effects of different aspects of EHR implementation could affect user satisfaction and perceived quality of EHRs. This study investigates the how time since implementation, training, and leadership affect user satisfaction and perceived quality of the …
Evaluation Of Catalytic And Non-Catalytic Production Of Biodiesel From Wet Microbial Media And Reaction Schemes, Adebola Titilope Coker
Evaluation Of Catalytic And Non-Catalytic Production Of Biodiesel From Wet Microbial Media And Reaction Schemes, Adebola Titilope Coker
Theses and Dissertations
Biodiesel is a renewable fuel that can supplement petroleum fuel supply. A major deterrent to commercial biodiesel production from traditional feedstock like soybean, canola or rapeseed oils is the high cost of feedstock: 70 - 95% of total biodiesel production cost. Therefore, a relatively cheaper feedstock is needed to make the price of biodiesel cost-competitive with petroleum diesel. Activated sludge from wastewater treatment plants is a relatively cheaper feedstock and relatively easy to obtain. However, drying of this sludge prior to oil extraction is a major operating cost of this process, as high as 50% of biodiesel production cost. The …

Theses and Dissertations
Screening for resistance to Aspergillus flavus and aflatoxin contamination in maize is an ongoing effort by universities, state and federal agencies. We evaluated two techniques to screen for resistance; quantitative polymerase reaction (QPCR) and solid-phase microextraction (SPME). Methods were adapted to accurately detect and quantify the fungus in culture and in the vegetative stage of plant tissues. These assays can eliminate microbiological techniques. The primary objectives of the study were to utilize 1) QPCR to detect and quantify fungal biomass in maize stem tissues to evaluate resistance in maize genotypes to A. flavus colonization in situ and in vivo and …
Evaluation Of Producing Sand-Based Sod On A Fine-Textured Native Soil Using Transported Sand, John David Vanderford
Evaluation Of Producing Sand-Based Sod On A Fine-Textured Native Soil Using Transported Sand, John David Vanderford
Theses and Dissertations
Turfgrass establishment on sand-based rootzones is routinely accomplished by using sod produced on a fine-textured native soil. As a result, soil layering occurs, potentially causing initial reduction in water infiltration, rooting, aeration, and overall turfgrass quality. This research was aimed at determining the feasibility of applying sand over existing native soil to produce hybrid bermudagrass (Cynodon dactylon [L.] Pers. x C. transvaalensis Burtt-Davy) sand-based sod. Factors evaluated were visual quality and scalping. Treatments were harvested and transplanted to a sand-based research green where handle-ability, tensile strength, and infiltration were also evaluated. Results indicate aerify and topdress treatments showed higher quality …
