The Epitome And Portrait Of Modern Society: Ouida As Social Barometer Of The Victorian Era, Lorraine Michelle Dubuisson

Electronic Theses and Dissertations

The Victorian Era was one of great social flux; tremendous advances in science and technology called into question deeply held religious beliefs while the changing legal status of women threatened to undermine traditional views of gender roles. Industrialization and the driving economic force of capitalism led to rapid urbanization as well as contributing to shifting class boundaries. In addition, the purpose and responsibilities of the Artist/Poet and, indeed, of art itself were closely scrutinized and hotly contested. Most frequently, historians and scholars of literature have looked to authors such as Charles Dickens, George Eliot, Oscar Wilde, and Alfred, Lord Tennyson …

Laughing Matters, Matthew Moore

Electronic Theses and Dissertations

This thesis defends a weak version of the superiority theory of humor: the superiority theory explains some instances of humor better than the incongruity theory. This thesis features an overview of the philosophy of humor in ancient, modern, and contemporary philosophy; this section contains criticisms of the incongruity theory. Connections between the superiority theory and humor about death are explored. Parallels are then drawn between this type of humor and Aristotle's great-souled man. A new type of laughter, jubilant laughter, is subsequently identified as being similar to laughter classified under the superiority theory since both exhibit a triumphant quality. But …

Panpsychism And Mind-Dust, John Heath Hamilton

Electronic Theses and Dissertations

It is only recently that panpsychism has emerged as a viable position in philosophy of mind and metaphysics. As such, the exploration and defense of it is not yet on par with some competing views. The current project is a step towards a remedy to this unfortunate state of affairs. It concerns one of the most important objections to the view, which I label the 'mind-dust' objection in homage to William James. It is essentially the conceptual difficulty of how proto-experiential being at the micro-level is supposed to 'sum' in a way that forms the consciousness with which we are …

Intersection(S) Between Sociocultural Knowledge, Classroom Discourse And Stance, John Munyui Muchira

Electronic Theses and Dissertations

Speakers of all languages align their talk to that of their peers in order to create identity in social discourse. While students' interactions in class reveal awareness of their personal educational achievements, they also exhibit a desire to inform others about their socio-cultural knowledge, their beliefs, and feelings. A number of studies have shown how participants create interactional environments where they can not only expand their knowledge in instructional styles but to a great extent construct and reconstruct their personas. Sociocultural knowledge and stancetaking has a great impact on classroom discourse and language learning. My study was conducted on an …

Introduction For Landslide Ecology, Lawrence R. Walker, Aaron B. Shiels

United States Department of Agriculture Wildlife Services: Staff Publications

1. The geological characteristics of landslides and their management as physical hazards are well documented. In contrast, the ecological processes that are initiated by landslides, and their relevance to efforts to restore stability to unstable slopes, have never been synthesized.

2. Landslides can cause intense human suffering and human activities can aggravate natural causes oflandslides. However, we can ameliorate many of the worst effects of landslides through improved prediction and restoration of landslides and adjoining slopes.

3. Landslides initiate many ecological processes at landscape to local scales, including the process of ecological succession. Although landslides have negative effects on the …

Wildlife In Airport Environments: Chapter 1 The History Of Wildlife Strikes And Management At Airports, Richard A. Dolbeer

United States Department of Agriculture Wildlife Services: Staff Publications

The first human-powered flight took place in December 1903, when Orville and Wilbur Wright successfully flew their experimental aircraft at Kitty Hawk, North Carolina, USA. Birds, which had been practicing powered flight for about 150 million years, suddenly had a new "competitor" for airspace, and the bird-aircraft collision problem (hereafter referred to as bird strikes) began shortly thereafter (Cleary and Dolbeer 2005). On 7 September 1905, the first reported bird strike, as recorded by Orville Wright in his diary, occurred when his aircraft hit a bird over a cornfield near Dayton, Ohio, USA. Flocks of red-winged blackbirds (Agelaius phoeniceus) and …

Landslide Ecology, Lawrence R. Walker, Aaron B. Shiels

United States Department of Agriculture Wildlife Services: Staff Publications

Despite their often dangerous and unpredictable nature, landslides provide fascinating templates for studying how soil organisms, plants, and animals respond to such destruction. The emerging field oflandslide ecology helps us to understand these responses, aiding slope stabilization and restoration and contributing to progress made in geological approaches to landslide prediction and mitigation. Summarizing the growing body ofliterature on the ecological consequences of landslides, this book provides a framework for the promotion of ecological tools in predicting, stabilizing, and restoring biodiversity to landslide scars at both local and landscape scales. It explores nutrient cycling; soil development; and how organisms disperse, colonize, …

Oral Rabies Vaccination Variation In Tetracycline Biomarking Among Ohio Raccoons, Timothy P. Algeo, Gary Norhenberg, Robert Hale, Andrew Montoney, Richard B. Chipman, Dennis Slate

United States Department of Agriculture Wildlife Services: Staff Publications

Oral rabies vaccination (ORV) programs have traditionally relied on tetracycline marking as an index to bait uptake. Whether tetracycline serves well in this capacity depends on its deposition affinity and ability to be detected consistently among tissues selected for analysis from target species. We evaluated samples from 760 hunter-harvested raccoons (Procyon lotor) from areas in Ohio where ORV had been conducted during 1998, 1999, and 2001. Tetracycline marking was evaluated within and among first premolar (PM1), second premolar (PM2), and canine (CN) teeth, and mandibular bone (MB) by side (left versus right); and by tissue type. Tetracycline detection ranged from …

Intraguild Relationships Between Sympatric Predators Exposed To Lethal Control: Predator Manipulation Experiments, Benjamin L. Allen, Lee R. Allen, Richard M. Engeman, Luke K.-P. Leung

United States Department of Agriculture Wildlife Services: Staff Publications

Introduction: Terrestrial top-predators are expected to regulate and stabilise food webs through their consumptive and non-consumptive effects on sympatric mesopredators and prey. The lethal control of top-predators has therefore been predicted to inhibit top-predator function, generate the release of mesopredators and indirectly harm native fauna through trophic cascade effects. Understanding the outcomes of lethal control on interactions within terrestrial predator guilds is important for zoologists, conservation biologists and wildlife managers. However, few studies have the capacity to test these predictions experimentally, and no such studies have previously been conducted on the eclectic suite of native and exotic, mammalian and reptilian …

Rabies, Canine Distemper, And Canine Parvovirus Exposure In Large Carnivore Communities From Two Zambian Ecosystems, Are R. Berentsen, Mike R. Dunbar, Matthew S. Becker, Jassiel M'Soka, Egil Droge, Nicholas M. Sakuya, Wigganson Matandiko, Rachel Mcrobb, Cathleen A. Hanlon

United States Department of Agriculture Wildlife Services: Staff Publications

Disease transmission within and among wild and domestic carnivores can have significant impacts on populations, particularly for threatened and endangered species. We used serology to evaluate potential exposure to rabies virus, canine distemper virus (CDV), and canine parvovirus (CPV) for populations of African lions (Panthera leo), African wild dogs (Lycaon pictus), and spotted hyenas (Crocuta crocuta) in Zambia’s South Luangwa National Park (SLNP) and Liuwa Plain National Park (LPNP) as well as community lands bordering these areas. In addition, domestic dogs in the study region were evaluated for exposure to CDV and rabies. We provide …

Population Management To Reduce The Risk Of Wiid Life-Aircraft Collisions, Richard A. Dolbeer, Alan B. Franklin

United States Department of Agriculture Wildlife Services: Staff Publications

Pour basic control strategies mitigate the risks to aviation caused by wildlife at airports: (1) aircraft flight schedule modification (primarily at military air· bases) and enhancement of aircraft visibility to avoid interactions with wildlife (e.g., Blackwell et a1. 2009b, 2012); (2) habitat modification and elimination of food, water, and cover that attract wildlife (Cleary and Dolbeer 2005, Blackwell et al. 2009a; Chapters 5, 8-10); (3) repellent and harassment techniques to disperse wild life (Cleary and Dolbeer 2005; Chapters 2-4); and (4) wildlife population management (e.g., Dolbeer 1998). As discussed throughout this book, successful efforts to mitigate the risk of wildlife-aircraft …

Prevalence Of Avian Paramyxovirus 1 And Avian Influenza Virus In Double-Crested Cormorants (Phalacrocorax Auritus) In Eastern North America, Tiffanie A. Cross, D. M. Arsnoe, R. B. Minnis, D. T. King, S. Swafford, K. Pedersen, J. C. Owen

United States Department of Agriculture Wildlife Services: Staff Publications

Although it is well established that wild birds, such as cormorants, carry virulent avian paramyxovirus serotype 1 (APMV-1; causative agent of Newcastle disease) and avian influenza virus (AIV), the prevalence of these viruses among Double-crested Cormorants (Phalacrocorax auritus) in the Great Lakes region of North America has not been rigorously studied. We determined the prevalences of APMV-1 and AIV in Double-crested Cormorants from the interior population of eastern North America. From 2009 to 2011, oropharyngeal and cloacal swabs and serum samples were collected from 1,957 individual Double-crested Cormorants, ranging from chicks to breeding adults, on breeding colony sites …

Understanding Animal Movements At And Near Airports, Jerrold L. Belant, Brian E. Washburn, Travis L. Devault

United States Department of Agriculture Wildlife Services: Staff Publications

Understanding movements of hazardous wildlife species at and near airports is critical to formulating effective management strategies for reducing aviation risk. Animal movements vary daily, seasonally, and annually and are based on broad biological and ecological concepts, including foraging, reproduction, habitat characteristics, dispersal, and migration. As an energy conservation strategy. most animals minimize their movements to meet life requisites, which in turn presumably improves fitness. Animal movements in relation to airports can be direct; for example, Canada geese (Branta canadensis) flying onto an airfield because grass height and composition are suitable for loafing sites and as food. Animal …

Determination Of An Immunocontraceptive Peptide In A Wildlife Vaccine Formulation, David A. Goldade, Jeffrey M. Kemp, Jeanette R. O'Hare, Lowell A. Miller

United States Department of Agriculture Wildlife Services: Staff Publications

Wildlife populations continue to grow despite the use of traditional management techniques. GonaCon™ Immunocontraceptive Vaccine is a vaccine used to reduce reproduction in mammalian species, including white-tailed deer (Odocoileus virginianus). The vaccine consists of synthetic gonadotropin releasing hormone (GnRH) conjugated to a mollusk hemocyanin (Concholepas concholepas) prepared as an emulsion with mineral oil to promote a prolonged immune response. Development of an analytical method for determination of the active ingredient in the vaccine formulation was complicated by the emulsion and conjugation of GnRH to the carrier protein. Breaking the emulsion was achieved chemically by addition of …

Procedures For Identifying Infectious Prions After Passage Through The Digestive System Of An Avian Species, Justin W. Fischer, Tracy A. Nichols, Gregory E. Phillips, Kurt C. Vercauteren

United States Department of Agriculture Wildlife Services: Staff Publications

Infectious prion (PrP^Res) material is likely the cause of fatal, neurodegenerative transmissible spongiform encephalopathy (TSE) diseases¹. Transmission of TSE diseases, such as chronic wasting disease (CWD), is presumed to be from animal to animal^2,3 as well as from environmental sources^4-6. Scavengers and carnivores have potential to translocate PrP^Res material through consumption and excretion of CWD contaminated carrion. Recent work has documented passage of PrP^Res material through the digestive system of American crows (Corvus brachyrhynchos), a common North American scavenger⁷.

We describe procedures used to document passage of …

Brownian Bridge Movement Models To Characterize Birds’ Home Ranges, Justin W. Fischer, W. David Walter, Michael L. Avery

United States Department of Agriculture Wildlife Services: Staff Publications

A Brownian bridge movement model (BBMM) is a relatively new concept that estimates the path of an animal’s movement probabilistically from data recorded at brief intervals. A BBMM assumes that locations are not independent, whereas the “classical” kernel-density estimator (KDE) assumes they are. We estimated BBMM home ranges for 11 Black Vultures (Coragyps atratus) and 7 Turkey Vultures (Cathartes aura) equipped with satellite transmitters near Marine Corps Air Station Beaufort, South Carolina, from October 2006 to November 2008. The 95% BBMM home ranges (95% BBMM) of the two Black Vultures that traveled >100 km from the …

Avian Influenza Infection Alters Fecal Odor In Mallards, Bruce A. Kimball, Kunio Yamazaki, Dennis Kohler, Richard A. Bowen, Jack P. Muth, Maryanne Opiekun, Gary K. Beauchamp

United States Department of Agriculture Wildlife Services: Staff Publications

Changes in body odor are known to be a consequence of many diseases. Much of the published work on disease-related and body odor changes has involved parasites and certain cancers. Much less studied have been viral diseases, possibly due to an absence of good animal model systems. Here we studied possible alteration of fecal odors in animals infected with avian influenza viruses (AIV). In a behavioral study, inbred C57BL/6 mice were trained in a standard Y-maze to discriminate odors emanating from feces collected from mallard ducks (Anas platyrhynchos) infected with low-pathogenic avian influenza virus compared to fecal odors …

Ecology Of Zoonotic Infectious Diseases In Bats: Current Knowledge And Future Directions, D. T. S. Hayman, R. A. Bowen, P. M. Cryan, G. M. Mccracken, T. J. O'Shea, A. J. Peel, A. T. Gilbert, C. T. Webb, J. L. N. Wood

United States Department of Agriculture Wildlife Services: Staff Publications

Bats are hosts to a range of zoonotic and potentially zoonotic pathogens. Human activities that increase exposure to bats will likely increase the opportunity for infections to spill over in the future. Ecological drivers of pathogen spillover and emergence in novel hosts, including humans, involve a complex mixture of processes, and understanding these complexities may aid in predicting spillover. In particular, only once the pathogen and host ecologies are known can the impacts of anthropogenic changes be fully appreciated. Cross-disciplinary approaches are required to understand how host and pathogen ecology interact. Bats differ from other sylvatic disease reservoirs because of …

Pheromonal Control Of The Invasive Brown Treesnake: Potency Of Female Sexual Attractiveness Pheromone Varies With Ovarian State, Tom Mathies, Breanna Levine, Richard M. Engeman, Julie A. Savidge

United States Department of Agriculture Wildlife Services: Staff Publications

The female sex pheromone has potential a s a control tool for the Brown Treesnake, Boiga irregularis Merrem, a pest introduced into Guam. We conducted male-guided bioassays to determine whether potency of the female pheromone varied according to reproductive state and during vitellogenesis. In weekly simultaneous choice tests, we presented males with skin lipid samples from vitellogenic females, non-vitellogenic females, conspecific males, and carrier controls. The total time each sample was tongue-flicked was recorded: mean total tongue-flick time was highest for samples from vitellogenic females followed by samples from non-vitellogenic females. Pair-wise comparisons of male tongue-flick time for samples of …

Feral Swine Brucellosis In The United States And Prospective Genomic Techniques For Disease Epidemiology, Owen P. Leiser, Joseph L. Corn, Brandon S. Schmit, Paul S. Keim, Jeffrey T. Foster

United States Department of Agriculture Wildlife Services: Staff Publications

Brucellosis is a common infection of feral swine throughout the United States. With the recent expansion of feral swine populations across the country, this disease poses an increasing threat to agriculture and hunters. The standard approach to Brucella surveillance in feral swine has been serological testing, which gives an indication of past exposure and is a rapid method of determining populations where Brucella is present. More in-depth analyses require bacterial isolation to determine the Brucella species and biovar involved. Ultimately, for a comprehensive understanding of Brucella epizootiology in feral swine, incorporation of genotyping assays has become essential. Fortunately, the past …

Home Ranges And Habitat Use Of Brown Pelicans (Pelecanus Occidentalis) In The Northern Gulf Of Mexico, D. Tommy King, Buddy L. Goatchter, Justin W. Fischer, John Stanton, James M. Lacour, Scott C. Lemmons, Guiming Wang

United States Department of Agriculture Wildlife Services: Staff Publications

Little is known about movements and habitat use of Brown Pelicans (Pelecanus occidentalis) in the northern Gulf of Mexico. We attached satellite transmitters to 18 adult Brown Pelicans (nine males, nine females) that were captured on Grand Isle along the Louisiana coast during 31 August-2 September 2010. Their movements and habitat use were tracked between September 2010 and March 2012. Nine of the Brown Pelicans remained proximate to the Louisiana coast; four ranged along the coasts of Alabama, Mississippi, and Louisiana; three moved from Louisiana to Texas; and two migrated across the Gulf of Mexico to the Yucatan Peninsula. …

The Use Of Contraception As A Disease Management Tool In Wildlife, Jack C. Rhyan, Lowell A. Miller, Kathleen A. Fagerstone

United States Department of Agriculture Wildlife Services: Staff Publications

Contraception offers potential as a tool for managing certain diseases in wildlife, most notably venereally transmitted diseases or diseases transmitted at parturition. Brucellosis is an excellent example of an infectious disease present in wild populations that could potentially be managed through immunocontraception. Previous studies in bison (Bison bison) suggest that a single injection of GonaCon^TM (National Wildlife Research Center, U.S. Department of Agriculture/Animal and Plant Health Inspection Service/Wildlife Services, Fort Collins, Colorado 80521, USA) results in 3 or more yr of infertility. Ongoing studies will determine if the use of GonaCon in bison decreases shedding of Brucella …

Failure Of Transmission Of Low-Pathogenic Avian Influenza Virus Between Mallards And Freshwater Snails: An Experimental Evaluation, Paul T. Oesterle, Kathryn P. Huyvaert, Darcy Orahood, Nicole Mooers, Heather Sullivan, Alan B. Franklin, J. Jeffrey Root

United States Department of Agriculture Wildlife Services: Staff Publications

In aquatic bird populations, the ability of avian influenza (AI) viruses to remain infectious in water for extended periods provides a mechanism that allows viral transmission to occur long after shedding birds have left the area. However, this also exposes other aquatic organisms, including freshwater invertebrates, to AI viruses. Previous researchers found that AI viral RNA can be sequestered in snail tissues. Using an experimental approach, we determined whether freshwater snails (Physa acuta and Physa gyrina) can infect waterfowl with AI viruses by serving as a means of transmission between infected and naı¨ve waterfowl via ingestion. In our …

Twenty Years Of Immunocontraceptive Research: Lessons Learned, Lowell A. Miller, Kathleen A. Fagerstone, Douglas C. Eckery

United States Department of Agriculture Wildlife Services: Staff Publications

The National Wildlife Research Center (NWRC) began immunocontraception vaccine research by testing porcine zona pellucida (PZP) on white-tailed deer (Odocoileus virginianus). Early PZP research demonstrated that PZP induced infertility; however, increased length of the rut was observed in PZP-treated deer. An alternative vaccine using a keyhole limpet hemocyanin-gonadotropin-releasing hormone (KLH-GnRH) conjugate formulated with modified Freund’s adjuvant was developed at NWRC. Suppression of GnRH has reduced reproduction in both sexes but is most effective in females. This vaccine was effective in preventing contraception in female deer for several years after a prime and boost. Due to adverse side effects …

Effects Of Black-Tailed Deer And Roosevelt Elk Herbivory In Intensively Managed Douglas-Fir Plantations, Jimmy D. Taylor Ii

United States Department of Agriculture Wildlife Services: Staff Publications

Black-tailed deer and Roosevelt elk are found throughout conifer-dominated Pacific Northwest forests west of the Cascade Crest, where they are important aesthetically, culturally, ecologically, and recreationally. Throughout their annual cycles, deer and elk use a variety of forest types and age classes to meet their basic requirements: food, water, cover, breeding, and young-rearing. Although their foraging strategies differ, black-tailed deer (browsers) and Roosevelt elk (grazers) often use the same forests. In general, forage plants for deer and elk are shade intolerant and are stimulated to grow when exposed to direct sunlight. As such, deer and elk often use clearcut patches …
