Appalachian Broadcast News Coverage Of The Coronavirus: A Content Analysis Of Media Framing In The Midst Of A Health Crisis, Jensen M. Mills

Graduate Theses, Dissertations, and Problem Reports (ETD)

Media framing of broadcast news is more than identifying an issue, but rather interpreting and explaining the issue for others to better understand. Previous framing scholarship in broadcast news, as well as COVID-19 specifically, has focused mostly on national or international news, so this research explores broadcast coverage from a local perspective in a rural location. During the health crisis of COVID-19, the specific use of media frames can impact how people made sense of the pandemic. Through a content analysis of 165 newscast scripts from five different local news stations in Appalachia, this study contributes to the understanding of …

Comparison Of Antimicrobials And Delivery Methods On The Inactivation Of Listeria Monocytogenes On Apples, Rebecca B. Stearns

Graduate Theses, Dissertations, and Problem Reports (ETD)

Introduction: Due to multi-state outbreaks of listeriosis on apples in 2015, 2017, and 2019, Listeria Monocytogenes (L. monocytogenes) has been deemed an emerging, under researched pathogen by the USDA-NIFA. Therefore, this study evaluated the efficacy of SaniDate 5.0®’s (SD) ability to inactivate L. Monocytogenes on apples when delivered through electrostatic sprayer (ES), garden sprayer (GS), and dip methods.

Methods: Organic apples were dip-inoculated with L. monocytogenes for 5 min and then dried for 10 min. Once dried, the inoculated apples were untreated (control), sprayed with water only, or treated with SD, 0.0064, 0.1, 0.25 and 0.50% for 20 …

Assessment Of Quechers Extraction Protocol For The Lc-Ms/Ms Detection Of Emerging Fentanyl Analogs In Biological Specimens For Clinical And Forensic Purposes, Kylea M. Morris

Graduate Theses, Dissertations, and Problem Reports (ETD)

Drug abuse within the United States is a dynamic and pervasive issue that affects the quality and life expectancy of our society. One of the major drug classes that are constantly utilized is opioids. Opioids are prescribed for pain management in patients suffering from cancer and other medical illnesses. Long-term use of opioids could lead to tolerance in humans, which poses a risk of reaching fatal overdose levels. Unfortunately, opioids are abused recreationally, and in some instances, individuals are unaware of the presence of dangerous synthetic drugs like fentanyl, hidden in materials such as heroin, cocaine, oxycodone, and methamphetamine. Recent …

Cross-Kingdom Interactions Shape Soil Biogeochemistry In Natural And Agricultural Ecosystems, Jennifer Lynne Kane

Graduate Theses, Dissertations, and Problem Reports (ETD)

Microorganisms influence life on earth in innumerable ways, including in medical, industrial, environmental, and agricultural contexts. Given the increasingly apparent consequences of climate warming, interest in how to better predict and manage Earth’s carbon sinks has never been greater. Soil, the largest terrestrial carbon sink, harbors an incredibly taxonomically and functionally diverse microbial community. These soil-dwelling microbes govern the fate of soil carbon and nutrients by cycling organic matter as they live, grow, and die. It has only been relatively recently that technological advancement has allowed for in-depth surveys of the vast diversity of soil microbes. High throughput analytical capabilities …

Constitutional Authority, Common Resources, And The Climate, Anthony Moffa

Utah Law Review

History, text, and precedent reveal an understudied and underutilized source of constitutional authority for environmental protection—the Property Clause of Article IV, Section 3. The Clause vests Congress with the “Power to dispose of and make all needful Rules and Regulations respecting the Territory or other Property belonging to the United States.” This work re-examines these words, the context in which they were written, and the limited judicial decisions interpreting them with an eye towards increased congressional reliance on the Property Clause in the face of daunting threats to our natural environment. Much prior scholarly explanation of the Property Clause focused …

Synergistic Effects Of A Domestic (Thiacloprid Based) Neonicotinoid Pesticide And Nitrogen, Phosphorus And Potassium Fertiliser On Common Earthworms (Lumbricus Terrestris)., Tristan Holmes

School of Biological and Marine Sciences Theses

Neonicotinoids are designed to target insect pests, but their extensive use and long persistence in soils mean that non-target soil organisms such as earthworms are likely to be chronically exposed to them. The common use of neonicotinoids in agricultural systems makes them highly likely to come into contact with other agro-chemicals that may give rise to synergistic effects. Chronic exposure of common earthworm (Lumbricus terrestris) to neonicotinoids in single or combined use with inorganic NPK fertiliser may pose problems that are not accounted for in most biological risk assessments under laboratory conditions. To assess the impacts of such chronic exposure …

Snake Community Ecology And Conservation In Cusuco National Park, Honduras, George Lonsdale

School of Biological and Marine Sciences Theses

The Mesoamerican biodiversity hotspot is threatened with agriculture related deforestation and global climate change, both of which drive widespread changes in forest composition. As the forests change, so too does the community of animals they can support; of which many reptiles have evolved micro-niches specific to these forests. Studying how these anthropogenic pressures affect the assemblages of animals that can persist there, could be vital in understanding how biodiversity will be affected on a global scale. Cusuco National Park (CNP), Honduras, is one of the most important protected sites worldwide for herpetofauna biodiversity, due to having such a high diversity …

A Phenotypic And Genomic Investigation Of The Identity And Variation In The European Dark Bee (Apis Mellifera Mellifera), Victoria G Buswell

School of Biological and Marine Sciences Theses

Apis mellifera (the Western honey bee) is a predominantly human managed pollinator consisting of different evolutionary lineages each containing a number of subspecies. Apis mellifera is threatened by various factors for example, parasites, viruses and pesticide use. The native subspecies of the British Isles Apis mellifera mellifera is additionally threatened by introgression resulting from the importation of foreign subspecies perceived to have more desirable characteristics. This thesis investigates the integrity of Apis mellifera mellifera in the UK and how that can be assessed. Initially, introgression levels over time in a conservation program were assessed. This revealed temporal decreases in introgression, …

Can You See Me, Or Can You Smell Me? An Investigation Into Information Transfer In Betta Splendens, Alex Daniel Lynch

School of Biological and Marine Sciences Theses

Visual communication in Betta splendens has been studied in great detail. Chemical information transfer in this species has been studied less, and the interaction between chemical and visual information transfer less still. Betta may have a need for chemical information transfer; a need which is often neglected when housing this species in isolation from conspecifics. There is evidence that many fish species communicate using visual signals and spy on one another using chemical cues. Which type of information transfer is important and how they interact in which social context is less clear. Eavesdropping and mate choice has been studied extensively …

Investigating The Microbiota Associated With Maerl Beds Located In The Fal Estuary, Cornwall, Anthony Scales

School of Biological and Marine Sciences Theses

The microbiota of maerl has the potential to contain diverse communities of bacteria which are thought to aid in maintaining maerl health and potentially be a driving factor in the settlement and development of ecological and economical important bi-valve species. However, little is currently known regarding the composition and structure of these communities, leading to uncertainty of their importance and their direct association to maerl beds. Using 16s amplicon sequencing analysis, the bacterial community composition associated with live and dead maerl (Phymatolithon calcareum) has been examined and compared to the communities associated with those of the surrounding environment - adjacent …

An Interdisciplinary Assessment Of The Mud Crab Scylla Serrata As A Sustainable Livelihood Resource In Southwest India, Elina Apine

School of Biological and Marine Sciences Theses

Fishing and aquaculture are important income-generating activities for coastal communities in India. However, the challenges of climate change and overexploitation have prompted the exploration of new, alternative, sustainable, target species that previously have received little attention. This thesis considers the potential of the mud crab Scylla serrata as a sustainable livelihood resource for local communities in southwest India where currently crab fishing and, particularly, farming is less common compared to southeast India. As fisheries and aquaculture are inherently complex social-ecological systems affected both by biological and socio-economic factors, this thesis has taken an interdisciplinary approach to identify the main barriers …

The Potential Impact Of Macroalgal Generated Hydrogen Peroxide Levels On Co-Occurring Organism In Rock Pools, Agapery Yoane Pattinasarany

School of Biological and Marine Sciences Theses

Abstract Macroalgae have been identified as a potential source of ROS (e.g., hydrogen peroxide) in some rock pools and enclosed habitats; the accumulation of ROS may be harmful to other organisms. Although some studies have found vulnerability to these ROS, there has been little research on the potential impact of photosynthesis-induced oxidative stress on organisms living in rock pools. The aims of this study were to investigate the levels of hydrogen peroxide produced by macroalgae and to assess the effect of similar levels of H2O2 on a rock-pool resident, the snakelocks anemone. The objective of the first experimental chapter was …

Intraspecific Variability In Thermal Tolerance Across Environmental Temperature Gradients In The Intertidal Periwinkle Littorina Saxatilis, Christopher Patrick Dwane

School of Biological and Marine Sciences Theses

Comparisons of thermal tolerance limits of organisms living across environmental temperature gradients represent a valuable means by which to study physiological adaptation. Intertidal organisms are subject to variation in levels of thermal stress both across latitude and shore height. However, our current understanding of how this variation relates to thermal adaptation is largely based on comparisons between species, and we lack a clear picture of the degree to which different populations from the same species display local adaptation along these temperature gradients. In this thesis, I investigate the extent and nature of intraspecific local adaptation of thermal tolerance across shore …

Late Ediacaran Inertial-Interchange True Polar Wander (Iitpw) Event: A New Road To Reconcile The Enigmatic Paleogeography Prior To The Final Assembly Of Gondwana, Bin Wen, Cairong Luo, Yong-Xiang Li, Yanting Lin

Turkish Journal of Earth Sciences

The Ediacaran to Early Cambrian plate tectonics was dominated by a full dispersal of the supercontinent Rodinia and the subsequent amalgamation of Gondwana. There is a consensus that the final assembly of Gondwana was not completed until the Early Cambrian. Prior to the final assembly, however, one major uncertainty remains on the quantitative paleogeography: the mainland of Gondwana was plausibly positioned at either a high or low latitude at a single time instant to meet the dual-latitude ('high-latitude' and 'low-latitude') options of Laurentia and the requirement of

Assessment Of Genetic Variation Of Natural Populations Of Wild Cherry (Prunus Avium L.)Via Ssr Markers, Burcu Uzan Eken, Emrah Kirdök, Ercan Veli̇oğlu, Yelda Özden Çi̇ftçi̇

Turkish Journal of Botany

Wild cherry (Prunus avium L, syn. Cerasus avium L. Moench.) is a widely spread forest tree that has ecological and economical importance. However, the genetic diversity of this species is threatened for many reasons. Therefore, a breeding and conservation program should be established in order to minimise the loss of genetic diversity. In this study, we aimed to understand the genetic structure of 440 individual wild cherries sampled from 22 different populations in Turkey using 10 SSR molecular markers. With the molecular variance analysis, we found that the genetic diversity within the population is approximately 88.5% and the genetic diversity …

Turkish Journal of Veterinary & Animal Sciences

As surgical site infection can prolong the patient's hospital stay, increase morbidity and mortality rates and medical and hospital expenses, justifying the search for new effective and low-cost antiseptic drugs is justifiable. Thus, the objective of the present study was to analyze, by direct clinical and microbiological examination, the topical antiseptic effect of a solution based on polyhexamethylene hydrochloride guanidine (PHMGH) at 0.5% on the intact skin surface of sheep and cats, aiming at its use in operative field (previous and definitive antisepsis), compared to 0.5% alcoholic chlorhexidine and association with this. The topical solutions did not cause any skin …

Speaking Up: School Climate And Language Politics In The Trump Era, Mneesha Gellman

Humboldt Journal of Social Relations

Identity politics are fraught. High school is a prime location where such politics play out and interface with state-dictated norms and values about acceptable social behavior. This article examines identity politics during the Trump era in two far Northern California high schools to better understand the impact on Black, Indigenous, and People of Color (BIPOC) students. I argue that while the Trump effect allowed hostility towards BIPOC people to be expressed more openly in general, schools can also be sites of resistance to culturecide—the killing of culture—that diminishes the role of minority ontologies and epistemologies in the formation of young …

Identifying Misconceptions About Evolution Relative To Science Curriculum Exposure At The Secondary Level, Rachel Carney

Graduate Research Papers

Evolution is the foundation of the biological sciences. Addressing misconceptions related to biological evolution ensures students have a solid understanding of evolution so that they can become scientifically literate members of society. While studies have identified misconceptions about evolution, there is much less research on the degree to which specific biology curricula address these misconceptions. The goal of this study is to determine how exposure to the SEPUP biology curriculum affects the misconceptions about evolutionary theory held by 10th grade students.

This study took place at a moderately-sized school located in the Midwest. Students respond with their agreeability to a …

The Decline Of Lake Superior's Woodland Caribou: A Historical Gis Analysis, Jordan W. Kelley

Dissertations, Master's Theses and Master's Reports

Lake Superior’s woodland caribou have been declining since the early 1800s. This thesis asks: why? We hypothesize that as settlers expanded into the region, industrial development in woodland caribou habitat reduced woodland caribou persistence. Using an Historical Geospatial Information System (HGIS) analysis, we find that historical mining and railroad infrastructure are associated with woodland caribou extirpation, while wetlands and protected areas are associated with caribou persistence. We also conducted a stakeholder synthesis of the region to help understand diverse perspectives within and between advocacy coalitions that take different positions on the most effective caribou restoration policies. Beliefs on recovery options …
