This study was carried out in the chicken coop of the Experimental Animals Ethics Committee, Faculty of Agriculture. This study constitutes the second phase of the study titled ?Effects of dietary guar meal with or without beta-mannanase on performance and egg quality traits in laying hens?, previously published. The experimental period lasted 126 days. Ninety-six Lohman Brown hens at the age of 56 weeks were and kept in individual …

Physiological Stress Responding During Negative Memory Recollection And The Habitual Use Of Psychological Coping Strategies, Kyle P. Rawn

Theses and Dissertations--Psychology

Coping represents an important process for stress: how effectively one copes dictates how a person experiences stress. However, research has not yet examined how a person’s long-term coping habits are related to their physiological stress responding during a particular situation. The current study addresses this through examination of skin conductance level (SCL) trajectories and coping tendencies (i.e. habitual use of coping strategies) during an autobiographical interview. 167 college students completed questionnaires assessing their demographics and their frequency of use for fourteen coping strategies. SCL was collected while participants recalled and discussed a negative family memory from their childhood. Multilevel modeling …

Distractors As A Tool To Increase “Self-Control” In Pigeons (Columba Livia), Peyton Mueller

Theses and Dissertations--Psychology

In the successive delay-discounting task, all trials start with a stimulus to which a response results in a small amount of reinforcement (smaller-sooner). If no response is made, the stimulus changes and a response results in a larger reinforcer (larger-later). The purpose of this study was to examine the use of a non-reinforced distractor (a stimulus to which responding has no programmed consequence) as a method of increasing the proportion of larger-later (LL) choices in a successive delay-discounting task. Earlier research studying the use of distractors may have inadvertently associated the distractor with reinforcement. Four experiments were conducted and each …

Pharmacokinetics And Reward-Related Behaviors Of Ethanol In Male And Female Japanese Quail (Coturnix Japonica), Shannon Eaton

Theses and Dissertations--Psychology

Ethanol is one of the most widely used and abused drugs. Problem use is associated with many different health problems and the economic burden is in the billions of dollars. Additionally, many people have difficulty controlling their ethanol consumption and about 5% of adults end up with an alcohol use disorder (AUD). Many people with an AUD often find themselves in a cycle of binge, remission, and relapse.

Following ethanol consumption ethanol enters the bloodstream from the small intestine where it gets distributed to peripheral tissues. Ethanol in the bloodstream is cleared from the system by the liver. The primary …

Russo-Ukrainian Patterns Of Genocide In The Twentieth Century, Amos Fox

Journal of Strategic Security

Russo-Ukrainian relations in the 20th Century are dominated by genocide. Using Raphel Lemkin and Martin Shaw as a guide, one finds that Russo-Ukrainian relations during the 20th Century was a long period of genocidal action, linked by periods of punctuated genocides. These genocides included several political genocides that quelled Ukrainian nationalism and independence and kept it subjugated to Soviet Russia. Soviet Russia's genocide during the 20th Century was a carryover from Imperial Russia treatment of Ukraine, the arch of which carries over into today's relations between the two countries. Understanding this long period of genocide helps make sense of the …

Avian Biodiversity Of The Indian River Lagoon System, Florida, Richard L. Turner

Ocean Engineering and Marine Sciences Faculty Publications

Despite claims about high avian biodiversity in the Indian River Lagoon system, previous efforts to inventory the birds have been limited in geographic extent or in habitat. Compilation of a list of birds could rely on many resources, but ones of widespread availability, greatest historical record, and highest density of sites are two citizen-science projects: the Christmas Bird Count (CBC) and eBird. Lists of species were harvested from 17 CBC sites (‘‘circles’’) back to 1910 and from 432 eBird sites (‘‘hotspots’’) since 2002 within the boundaries of the Indian River Lagoon National Estuary Program (IRLNEP). In addition to lagoon waters, …

Biodiversity Of The Indian River Lagoon System: A Cautionary Tale From The Birds, Richard L. Turner

Ocean Engineering and Marine Sciences Faculty Publications

Prevailing dogma on comparative biodiversity of the Indian River Lagoon (IRL) stems mainly from one claim about ichthyofauna and two about avifauna. The extensive network of birdwatchers, clarity of bird taxonomy, long history of the Christmas Bird Count (CBC), and burgeoning database on ebird.org make birds excellent for geographic comparison. The 1985 claim that Merritt Island CBCs are often the ‘‘most speciose count’’ in the U.S. is unfounded. CBCs there in 1970–1985 never had the highest count, even compared to the nearby Cocoa site. For the 114th CBC (2013), it ranked 11th in Florida and 44th nationally. The 1989 claim …

Investigating The Roles Of Lipids In Staphylococcus Aureus Infection, Xi Chen

Dissertations

The Gram-positive bacterium Staphylococcus aureus is a major threat to public health and causes a multitude of infections, ranging from mild skin and soft infection, to more severe diseases including sepsis, osteomyelitis and infective endocarditis. As a successful pathogen, S. aureus employs various mechanisms to invade host tissues, evade immune responses, and survive in the host environment. One critical adaptive trait of S. aureus that promotes virulence and survival is the ability to maintain membrane homeostasis via flexible modifications to its lipid composition in response to the surrounding lipid environment. Phospholipids are the major component of the bacterial membrane and …

Reading Ethics: Modernism, Narrative, Violence, Katie Dyson

Dissertations

Reading Ethics hinges on the relationship between its two central terms, tracing how modernist narrative innovations reimagined reading as an ethical practice. To ask how we read is to return to a core question for the discipline. Building on recent reevaluations of reading methodologies by Rita Felski, Sharon Marcus and Stephen Best, and other scholars, I argue that modernist narrative forms foreground the ethical dynamics between text, reader, and world, asking readers to rethink how we understand the world even as they work to build new ones. Focusing on British and American modernist and meta-modernist fiction from writers such as …

Il-27 Signaling In The Maintenance Of Intestinal Barrier Following Ethanol Intoxication And Burn Injury, Marisa Luck

Dissertations

Roughly half of burn patients that are hospitalized in the United States each year have detectable blood alcohol levels. Alcohol intoxication at the time of burn injury leads to worse outcomes, including longer hospital stays, increased rates of infection, and death. One of the severe consequences of intoxication and burn injury is the disruption of the gastrointestinal (GI) tract, which houses the largest reservoir of bacteria in the human body. Leakiness of the gut barrier can contribute to inflammation, infection, or sepsis from gut-derived microbes. Interleukin-27 (IL-27) is a cytokine that has shown some beneficial effects in other models of …

Comparative Studies On Biochemical And Pharmacological Profiles Of Unfractionated Heparins & Their Depolymerized Derivatives From Bovine, Ovine And Porcine Origins, Ahmed Kouta

Dissertations

Heparin and heparin related drugs have remained the anticoagulant of choice for medical and surgical indications. These drugs are comprised of poly-component sulfated chains of varying length and biophysical structure with direct and indirect pharmacological effects. Heparins produce their therapeutic effects by multiple mechanisms involving both the cellular and humoral targets. These drugs represent natural products which are isolated from mammalian tissue rich in mast cells. Currently used heparin and LMWHs are obtained from porcine mucosal tissue. Other animal sources including bovine and ovine tissues also provide additional sources for the manufacturing of heparins. While there may be microchemical and …

The Role Of The Co-Chaperone Protein Bcl-2-Associated Athanogene 3 (Bag3) At The Cardiomyocyte Sarcomere, Thomas Gwynn Martin

Dissertations

The co-chaperone protein Bcl-2-associated athanogene-3 (BAG3) is a central mediator of cellular protein quality control through autophagy. In the heart, decreased BAG3 activity through mutation or decreased expression are linked to dilated cardiomyopathy (DCM). Unfortunately, though clinical data indicates BAG3 mutations are a definitive cause of DCM, few mechanistic studies had been performed to decipher the fundamental role of BAG3 in cardiomyocytes. However, several studies suggested BAG3 was involved in maintenance of the sarcomere, the molecular contractile structure in muscle cells. The goals of this dissertation were to: 1. Determine the functional significance of BAG3 for the sarcomere, 2. Identify …

Cardioprotective Extracellular Vesicles Derived-Micrornas: Sorting Mechanisms And Functions, Anh P. Phan

Dissertations

Extracellular vesicles (EVs) are nano-size membrane bound vesicles that are derived from the fusion of multivesicular endosomes with the plasma membranes. EVs have important roles in intercellular communication through the transfer of their unique cargoes including RNA, DNA and protein molecules to recipient cells. Mesenchymal stem cell (MSC)-derived EVs have been shown to reduce infarct size and reduce the progress of heart failure after cardiac ischemia/reperfusion (I/R) injury in animal models. Small non-coding RNAs such as microRNA (miRNA) have been indicated as one of the active components that mediate the beneficial effects of MSC-derived EVs. However, the selective packaging mechanisms …

Environmental Reforestation And Social Justice In Cameroon: A Test Case For Pope Francis' Concept Of 'Integral Ecology' In Laudato Sí, Augustin Vondou

Dissertations

The following quotation from Pope Francis' encyclical Laudato Sí is one of the most quoted parts of his well-known encyclical: We are faced not with two separate crises, one environmental and the other social, but rather with one complex crisis which is both social and environmental. Strategies for a solution demand an integrated approach to combating poverty, restoring dignity to the excluded, and at the same time protecting nature (139).

This is a very challenging statement. Not everyone accepts this idea of an ‘integral ecology’; that is, the notion that the condition of human society is directly linked to the …

An Appraisal Of E-Health Information Literacy Of Students, Gurpreet Singh, Preeti Sharda Dr., Sanjay Chandwani, Nirmal Singh

Library Philosophy and Practice (e-journal)

Health Information Literacy (HIL) is the competence to make sound health decisions in context of everyday life, which is pivotal in abridging illness and wellness. While the emergent Information and Communication Technologies (ICTs) have facilitated access to information to users’ palms, the bewildering nature of abundance of information available makes it difficult for users’ to decide which information is to be trusted and which is to be ignored. Thus, HIL in contemporary electronic era assumes more significance to have a healthy global society. The present study was conducted for desideratum of e-Health Information Literacy skills of college students, to …

Ethical Health Care In An African Context: Linking Conventional Medicine And Traditional Healing Practices In Igboland, Nigeria., Michael Osondu Okoro

Dissertations

This dissertation argues that in Nigeria’s Igboland, a health care ethic reflective of the Roman Catholic Christian faith must build links between the rightful practices of both conventional Western medicine and traditional Igbo healers. It calls such a health care ethic an “integral health care ethic” in the Nigerian Igbo context.The inspiration for this dissertation comes from the growing respect given to indigenous people and their knowledge by the Roman Catholic Church since the Second Vatican Council and, more specifically, the attention Pope Francis has given to indigenous people in his writings and speeches. For example, in his remarks on …

Hemingway, Sartre, And Secularization: Finding Religion Without God, Marcos Antonio Norris

Dissertations

This dissertation intervenes in the critical debate over Ernest Hemingway’s religious orientation. One camp of Hemingway scholars argues that he was a practicing Catholic, while the other camp argues that Hemingway was an existential atheist. Rather than side with either camp in this binary debate, my research offers a third option that bridges the gap between these opposing positions. Examining Hemingway’s life and works through the eyes of contemporary political philosopher Giorgio Agamben, I argue that Hemingway is, properly speaking, neither a secularist nor a theist, but a secularized theist, whose “religion” takes the form of masculine volition, or sovereign, …

Small Unmanned Aircraft Systems Acoustic Analysis For Noninvasive Marine Mammal Response: An Exploratory Field Study, David Thirtyacre, Gennifer Brookshire, Sarah Callan, Brittany Arvizu, Patrick Sherman

International Journal of Aviation, Aeronautics, and Aerospace

As in countless other fields of human endeavor, small unmanned aircraft systems (sUAS) have the potential to benefit pinniped (Pinnipedia; e.g., Phocidae [seals], Otariidae [sea lions], and Odobenidae [walruses]) response efforts. The employment of sUAS could give responders a close-up look at animals in distress in order to determine their condition as well as develop a response strategy. However, unlike other subjects that are regularly inspected by sUAS (e.g., croplands and civil infrastructure) pinnipeds may respond to the distinctive sound generated by small, multirotor sUAS. This reaction may include retreating into the water en masse, which could put …

Identification Of Wind-Induced Hazard Zones Impacting Uas Bridge Inspection, Jack J. Green, John Mott

International Journal of Aviation, Aeronautics, and Aerospace

Unmanned Aerial Systems (UAS) continue to grow in both popularity and utility within the national airspace system. The use of commercial UAS for civil inspection, specifically that of bridge structures, is becoming commonplace among practitioners and academics alike. The development of an integrated bridge-inspection hazard model provides a way for UAS operators to prepare for and respond to changing environmental conditions that could otherwise prevent a successful UAS flight. The interaction of wind-induced airflow with bridge surfaces creates an aerodynamic wake that can result in hazardous conditions for a UAS platform operating in close proximity. An analysis of this airflow …

The aerodynamic simulation carried out to understand the aerodynamic performance of a bio-mimetic dragonfly corrugated airfoil at low Reynolds number range of 75000-150000 to explore the potential advantages of pleated airfoils at a varying angle of attack from 0° to 12°. CFD analysis accomplished by using ANSYS Fluent to understand the aerodynamic performance of the …

‘Whether The Elves Are Watching Or Not’. Listening To Teachers’ Experiences Regarding Surveillance Technologies In Schools., Martin Edward Edmonds

Plymouth Institute of Education Theses

Abstract Surveillance technologies have become a normalised aspect of the workplace, and daily life, in England. This is particularly true in schools, where CCTV (Closed Circuit Television) is commonplace, and an audit culture well established. This study explores how teachers feel the atmosphere and culture of a school is influenced by technologized surveillance tools. Three interrelated questions were explored; what effect do surveillance technologies in schools have upon relationships between colleagues and students? What is lost by the application of such surveillance technologies in schools? How can Ivan Illich’s work show us a way to respond? To explore these questions, …

Optimising Oak Woodland Establishment Into Uk Upland Pastures In The Context Of Climate Change; And The Role Of Oak Woodland In Soil Hydrological Recovery For Natural Flood Management, Thomas Murphy

School of Geography, Earth and Environmental Sciences Theses

Increases in the magnitude and extremity of upland (>250-300m a.s.l.) precipitation associated with anthropogenic climate change (ACC) and coinciding with soil compaction leave downstream communities at elevated flood risk. The study examines changes in upland precipitation and the impact of upland ‘Atlantic’ oak (Quercus robur, Quercus petraea) woodland establishment on the recovery of soils for natural flood management (NFM). The soil moisture, livestock grazing and dispersal constraints for potential oak woodland expansion in upland pastures are assessed. The study is located within Dartmoor National Park (DNP) and finds greater increases in precipitation in upland areas than the lowland site, …

Evaluating The Emerging Environmental Risks Of Mycotoxins In Freshwater Ecosystems., Emily Eagles

School of Geography, Earth and Environmental Sciences Theses

Deoxynivalenol (DON) and zearalenone (ZON) are two of the prominent mycotoxins which regularly contaminate food, both of these natural toxins are produced by fungi within the Fusarium genus. With the known widespread occurrence of these toxins in cereal crops there has been rising interest into the potential transference into freshwaters. Multiple reports of mycotoxin occurrence in freshwater samples have led to their consideration as natural chemicals of emerging concern, particularly with ZON seen to act in an oestrogenic nature, yet the ecotoxicological data to support analysis of risk to freshwater ecosystems is lacking. The main aim of this work was …

Across The River: Ferries As A Vehicle For Exploring Riverborderscapes, Eva Mcgrath

School of Geography, Earth and Environmental Sciences Theses

This thesis uses the concept of the riverborderscape to provide new understandings of watery geographies, borders and landscape. This is a spatial and conceptual term used to explore the space of the river through a holistic approach, focusing upon the materialities, experiences and narratives that shape, emerge within and construct this space. These ideas are applied in relation to three rivers that form an everyday border between places at different scales in the South West of England: the River Tamar (regional), River Torridge (district) and Helford River (parish). Research is situated on and across the river, through the routes of …

Visual Anthropological Methods In Earthquake Risk Communication: A Transdisciplinary Approach, Johanna Ickert

School of Geography, Earth and Environmental Sciences Theses

Increases in disaster losses, in combination with emerging cascading crises, are provoking a fundamental rethinking of prevailing disaster risk reduction measures, including risk communication principles and practices. The resulting paradigm shift towards participation, action, and prevention is firmly outlined in the Sendai Framework’s call for (1) more people-centred approaches and (2) the broader use of innovative information and communication technology (ICT). However, this call raises many epistemological and methodological challenges and open questions about how hazard scientists will translate these novel requirements into their daily research practice. This thesis presents a practice-led enquiry dedicated to exploring the potential of audiovisual …

Employability As Sustainable Balance Of Stakeholder Expectations - Towards A Model For The Health Professions, Martin Cake, Melinda Bell, Liz Mossop, Caroline F. Mansfield

Health Sciences Papers and Journal Articles

The conceptual complexity of employability remains a barrier for its integration into discipline-based curricula. In the health professions, a particular challenge lies in integrating employability with the dominant paradigms of competency and professionalism. In this study, we explore these contextual challenges, and present the rationale and conceptual basis for a potential re-framing of employability within the context of this discipline group. We propose a novel definition and a conceptual model of employability better aligned to the needs of health professions. While employability has proven difficult to define broadly, it is framed around the expectations of both the employer and employee, …

Different Ways Of Knowing And Growing: A Case Study Of An Arts-Integrated Pedagogy At An Urban Elementary Charter School, Amarpal Khanna

LMU Theses and Dissertations

An arts equity gap exists in K–12 grade education. African American and Latinx students have fewer opportunities for access to arts education than do White students. In California, charter schools have an opportunity to address the equity gap for students in those demographic groups. The goal of this qualitative case study was to observe how Kahlo Charter Elementary School, an urban charter elementary school in Los Angeles County, implemented an arts integrated curriculum and to identify benefits and challenges for fourth and fifth grade students of color enrolled at the school. Aesthetic learning (Bose, 2008; Denaway, 2013; Greene, 1978, 1995, …

Addressing Urgent Questions For Pfas In The 21st Century, Carla Ng, Ian T. Cousins, Jamie C. Dewitt, Juliane Glüge, Gretta Goldenman, Dorte Herzke, Rainer Lohmann, Mark Miller, Sharyle Patton, Martin Scheringer, Xenia Trier, Zhanyun Wang

Graduate School of Oceanography Faculty Publications

Despite decades of research on per- and polyfluoroalkyl substances (PFAS), fundamental obstacles remain to addressing worldwide contamination by these chemicals and their associated impacts on environmental quality and health. Here, we propose six urgent questions relevant to science, technology, and policy that must be tackled to address the “PFAS problem”: (1) What are the global production volumes of PFAS, and where are PFAS used? (2) Where are the unknown PFAS hotspots in the environment? (3) How can we make measuring PFAS globally accessible? (4) How can we safely manage PFAS-containing waste? (5) How do we understand and describe the health …
