Given their free-ranging habits, feral swine could serve as reservoirs or spatially dynamic ‘mixing vessels’ for influenza A virus (IAV). To better understand virus shedding patterns and antibody response dynamics in the context of IAV surveillance amongst feral swine, we used IAV of feral swine origin to perform infection experiments. The virus was highly infectious and transmissible in feral swine, and virus shedding patterns and antibody response dynamics were similar to those in domestic swine. In the virus-inoculated and sentinel groups, virus shedding lasted ≤6 and ≤9 days, respectively. Antibody titres in inoculated swine peaked at 1 : 840 on …

Titanium Dioxide Nanoparticles Trigger Loss Of Function And Perturbation Of Mitochondrial Dynamics In Primary Hepatocytes, Vaishaali Natarajan, Christina L. Wilson, Stephen L. Hayward, Srivatsan Kidambi

Department of Chemical and Biomolecular Engineering: Faculty Publications

Titanium dioxide (TiO₂) nanoparticles are one of the most highly manufactured and employed nanomaterials in the world with applications in copious industrial and consumer products. The liver is a major accumulation site for many nanoparticles, including TiO₂, directly through intentional exposure or indirectly through unintentional ingestion via water, food or animals and increased environmental contamination. Growing concerns over the current usage of TiO₂ coupled with the lack of mechanistic understanding of its potential health risk is the motivation for this study. Here we determined the toxic effect of three different TiO₂ nanoparticles (commercially available …

Animal Reactions To Oncoming Vehicles: A Conceptual Review, Steven L. Lima, Bradley F. Blackwell, Travis L. Devault, Esteban Fernández-Juricic

United States Department of Agriculture Wildlife Services: Staff Publications

Animal–vehicle collisions (AVCs) are a substantial problem in a human-dominated world, but little is known about what goes wrong, from the animal’s perspective, when a collision occurs with an automobile, boat, or aircraft. Our goal is to provide insight into reactions of animals to oncoming vehicles when collisions might be imminent. Avoiding a collision requires successful vehicle detection, threat assessment, and evasive behaviour; failures can occur at any of these stages. Vehicle detection seems fairly straightforward in many cases, but depends critically on the sensory capabilities of a given species. Sensory mechanisms for detection of collisions (looming detectors) may be …

The Effect Of Social Context And Social Scale On The Perception Of Relationships In Monk Parakeets, Elizabeth A. Hobson, Darlene J. John, Tiffany L. Mcintosh, Michael L. Avery, Timonthy F. Wright

United States Department of Agriculture Wildlife Services: Staff Publications

Social relationships formed within a network of interacting group members can have a profound impact on an individual’s behavior and fitness. However, we have little understanding of how individuals perceive their relationships and how this perception relates to our external measures of interactions. We investigated the perception of affiliative and agonistic relationships at both the dyadic and emergent social levels in two captive groups of monk parakeets (Myiopsitta monachus, n = 21 and 19) using social network analysis and playback experiments. At the dyadic social scale, individuals directed less aggression towards their strong affiliative partners and more aggression …

Antibody Response Of Cattle To Vaccination With Commercialmodified Live Rabies Vaccines In Guatemala, Amy T. Gilbert, Lauren Greenberg, David Moran, Danilo Alvarez, Marlon Alvarado, Daniel L. Garcia, Leonard Peruski

United States Department of Agriculture Wildlife Services: Staff Publications

Vampire bat rabies is a public and animal health concern throughout Latin America. Aspart of an ecological study of vampire bat depredation on cattle in southern Guatemala,we conducted a vaccine seroconversion study among three dairy farms. The main objec-tives of this cross sectional and cohort study were to understand factors associated withbat bites among cattle, to determine whether unvaccinated cattle had evidence of rabiesvirus exposure and evaluate whether exposure was related to bat bite prevalence, and toassess whether cattle demonstrate adequate seroconversion to two commercial vaccinesused in Guatemala. In 2012, baseline blood samples were collected immediately prior tointramuscular inoculation of …

Appraisal Of Caregiving Burden, Expressed Emotion, And Psychological Distress In Families Of People With Dementia: A Systematic Review, Susan L. Sprokay

Theses and Dissertations

Unpaid family caregivers of people with dementia are faced with a variety of physical, emotional and social stressors. A systematic review of the literature was compiled to summarize existing evidence regarding subjective burden, expressed emotion and psychological distress related to this category of caregiving and to build a multinational representation of these individuals that will facilitate in identifying areas of supportive intervention. A synthesis of 44 data sets that included 5,249 participants from 20 countries indicated that the majority of caregivers are experiencing depression and high levels of distress related to their caregiving role, and that a small number of …

Utilization Of The Multidimensional Well-Being Assessment To Understand Well-Being In Individuals With Chronic Medical Conditions/Illnesses, Jaqulyn Spezze

Theses and Dissertations

This study examined multiple dimensions of well-being among adults with chronic medical conditions/illnesses utilizing the Multidimensional Well-Being Assessment (MWA). Specifically, the dimensions of well-being that were assessed included physical, emotional, and relational, as well as dimensions of well-being that have not previously been studied in individuals with chronic medical conditions/illnesses, such as collective and transformational well-being. A non-random sample of 268 participants with chronic medical conditions/illnesses completed multiple measures of well-being as part of a larger psychometric investigation of the MWA. Significant positive correlations were found between physical well-being and measures of subjective well-being assessing satisfaction with life, flourishing, and …

Redefining Synchronous Learning For The 21st Century: A Descriptive Case Study To Examine Multi-Channel Synchronous Online Communication And Critical Thinking, Mary Wegner

Theses and Dissertations

Students in the 21st century seek connection with each other through synchronous online avenues, yet the education community does not embrace the use of synchronous online tools within the formal process of schooling. This creates a disconnect between the way that students learn outside of school and the way that they are schooled. In addition to matching the communication patterns of students, synchronous online tools provide opportunities for participants to communicate using a number of channels (audio, text, and interactive media) within a single communication environment. An important and useful perspective in this regard is to view the multi-channel environment …

The Role Of The Chief Executive Officer: Unlocking The Full Potential Of Women Leaders, Pamela A. Miller

Theses and Dissertations

This qualitative research study examined the role of the chief executive officer (CEO) in achieving an inclusive environment, specifically reviewing the messaging and actions of the CEO and how they impact executive women. Data were gathered from 15 executive women through interviews with predetermined, semi-structured questions. This study provides evidence that CEOs can create an inclusive environment by instilling an atmosphere of mutual respect, openly listening and valuing diverse perspectives, and encouraging healthy dialogue and debate. Internal competition, an imbalance of power, and perceived bias on the part of the CEO hindered participants from feeling like equal partners in the …

Long-Term Characterization Of The Chronic Dopamine Microelectrode And Effect Of Electrical Conditioning, Eric P. Marr

EWU Masters Thesis Collection

Background: Dopamine (DA) is a neurotransmitter involved in movement, reward learning and addiction. Fast-scan cyclic voltammetry (FSCV) has long been an indispensable tool for monitoring real-time DA signaling. Development of polyimide fused silica-encased FSCV microelectrodes have made the technique more suitable for chronic DA monitoring (months) in vivo. Methods: In this study, electrically stimulated DA signals were evoked weekly in an effort to characterize the recovery time and stability of DA signals recorded long-term with silica-encased chronic DA microelectrodes. Additionally, electrical conditioning (etching), previously shown to improve microelectrode sensitivity in vitro, was performed to investigate the long-term impact on DA …

The Dietary Mineral Content Of Claytonia Lanceolata Corms From Multiple Populations Across The Columbia Plateau Region Of North America, Paul Reilly

EWU Masters Thesis Collection

"Since divergence from our ancestral lineage ~ 2.8 mya, humans have relied on foraged foods to obtain dietary mineral nutrition. Around 12,000 years ago, people began shifting towards a lifestyle of food production. The rapid shift in lifestyle significantly altered the human diet, and research suggests our genomes have had insufficient time to adjust. Due to the discord between genome and environment, unprecedented levels of disease and malnutrition are epidemic in certain subsets of the population. Studies suggest the most cost effective way to mitigate the risk of these diseases is to find ways to increase micronutrient consumption. As a …

Smallmouth Bass Abundance And Diet Composition In The Upper Spokane River, Michael Taylor Mccroskey

EWU Masters Thesis Collection

"I conducted a three month study, between June and August, in 2015 of Redband Trout (Oncorhynchus mykiss var. gairdneri) and Smallmouth Bass (Micropterus dolomieu) in the upper Spokane River in Washington, from the border between Washington and Idaho (rkm 154.5) to Harvard Road (rkm 149.2). The primary goals of the project were to: (1) determine the abundance and density of Redband Trout and Smallmouth Bass in the Starr Road area, as well as two reference sites, prior to possible habitat manipulation, (2) estimate the Smallmouth Bass population and density between the Washington/Idaho Stateline and Harvard Road, and (3) determine the …

Ovulation Synchrony As An Adaptive Response To Egg Cannibalism In A Seabird Colony, Sumiko Weir

Honors Theses

The predominant cause of egg loss in a large Galucous-winged Gull (Larus glaucescens) colony in Washington is cannibalism. Previous work demonstrated the occurrence of every-other-day clutch initiation synchrony in dense areas of the colony during years when cannibalism was most frequent, suggesting that synchrony is an adaptive response to cannibalism. Here we show that (1) the initial egg laid in a nest is more likely to be cannibalized than subsequent eggs, (2) an egg is most likely to be cannibalized within the first 24 hours after it is laid, and (3) the odds that an initial egg is cannibalized within …

The Behavior Of Glaucous-Winged Gull Egg Cannibals, Ashley A. Reichert

Honors Theses

Cannibalism leads to a variety of behavioral, demographic, and ecological consequences and is influenced by a range of environmental circumstances among numerous taxa. Although multiple studies have linked cannibalism to egg and chick failure in gull populations, few characterizations of gull cannibal behavior and reproductive success exist. During the 2014 breeding season, we observed the territories of 16 Glaucous-winged Gull (Larus glaucescens) and Glaucous-winged x Western Gull (L. glaucescens x occidentalis) egg cannibal specialists on Protection Island, Washington, USA. We also monitored cannibal foraging behavior, relative reproductive success, and colony-wide egg loss. Cannibal specialists employed a variety of foraging and …

Adamts-4 And Adamts-5 Expression In Human Temporomandibular Joint Discs With Internal Derangement, Correlates With Degeneration, Rosalia Leonardi, Salvatore Crimi, Luis Eduardo Almeida, Giuseppe Pannone, Giuseppe Musumeci, Sergio Castorina, Mugurel Constantin Rusu, Carla Loreto

School of Dentistry Faculty Research and Publications

Temporomandibular joint (TMJ) internal derangement (ID) is one of the most common form of temporomandibular disorders. There is evidence showing the increased expression of matrix metalloproteinases (MMPs) in the cells from degenerated TMJ disc. ADAMTS are a large family of metalloproteases which are responsible for proteoglycans degradation. The present study aimed to evaluate ADAMTS-4 and ADAMTS-5 immunohistochemical expression in human TMJ discs from patients affected by ID, and to find out if there is any correlation with the degree of histopathological changes. Eighteen temporomandibular displaced disc specimens and sixteen TMJ disc control were used for the present study. Specimens were …

Acute Effects Of Dynamic Stretching On Flexibility And Agonist-Antagonist Muscle Activity, Lance T. Beisley

EWU Masters Thesis Collection

"Flexibility is an important determinant of health and important in sport performance. ADS and SPST are the methods most often used in training flexibility for sport. Although ADS appears to dominate SPST in measures of power and agility, the mechanisms are unclear. The purpose of this study was to delineate the effects of ADS on AROM and agonist-antagonist mean and peak EMG. The ADS protocol involved three sets of ten repetitions of leg kicks while in the supine position with the pelvis and contralateral limb fixed in extension. Participants moved the leg at the hip in a kicking motion to …

Legitimacy And Expertise In Global Internet Governance, Olivier Sylvain

Faculty Scholarship

Over the course of the past decade or so, attention among Internet policymakers and scholars has shifted gradually from substantive design principles to the structure of Internet governance. The Internet Corporation for Assigning Names and Numbers in particular now faces a new skepticism about its legitimacy to administer the essential Internet Assigned Numbers Authority function. ICANN has responded to these doubts by proposing a series of major governance reforms that would bring nation-states more into the organization's decisionmaking. After all, transnational governance institutions in other substantive areas privilege nation-states as a matter of course. This Symposium Essay shows that these …

Marriage As Black Citizenship?, Robin A. Lenhardt

Faculty Scholarship

The narrative of black marriage as citizenship enhancing has been pervasive in American history. As we mark the fiftieth anniversary of the Moynihan Report and prepare to celebrate the 150th anniversary of Thirteenth Amendment, this Article argues that this narrative is one that we should resist. The complete story of marriage is one that involves racial subordination and caste. Even as the Supreme Court stands to extend marriage rights to LGBT couples, the Article maintains that we should embrace nonmarriage as a legitimate frame for black loving relationships — gay or straight. Nonmarriage might do just as much, if not …

Exploiting Bacteriophages And Associated Peptidoglycan Hydrolases With Potential For Biocontrol In Food Related Applications, Lorraine Endersen

Theses

The work presented in this thesis describes the isolation and characterisation of novel bacteriophages, and the subsequent exploitation of their bactericidal properties against two opportunistic food related pathogens, Mycobacterium avium subsp. paratuberculosis (MAP) and Cronobacter sakazakii.

MAP is a proven animal pathogen known to cause Johne’s disease in cattle but has been implicated as a causative agent of Crohn’s disease in humans. Despite the fact that this association has yet to be proven, significant focus has been directed towards evaluating the consequences of consuming milk contaminated with MAP. Accordingly, six mycobacteriophages were isolated and characterised in terms of temperature and …

Expression And Characterization Of Ecm14, A Metallocarboxypeptidase From Saccharomyces Cerevisiae, Matthew James Schott

Master's Theses

Metallocarboxypeptidases are found in most organisms and function in the digestion and maturation of proteins. Ecm14 is a putative metallocarboxypeptidase found in the yeast Saccharomyces cerevisiae vacuole. The function of Ecm14 as an enzyme has been unclear due to the presence of active site amino acids not typically found in metallocarboxypeptidases, suggesting either no enzymatic activity or a unique mechanism. In order to investigate the enzymatic mechanism of Ecm14, expression of histidine-tagged Ecm14 protein was attempted in human HEK293T cell culture, S. cerevisiae, and baculovirus expression systems. No expression was detected in HEK293T cells in preliminary experiments. Expression in the …
