Environmental Contaminant Concentrations In Canada Goose (Branta Canadensis) Muscle: Probabilistic Risk Assessment For Human Consumers, Katherine E. Horak, Richard Chipman, Lisa Murphy, John Johnston

United States Department of Agriculture Wildlife Services: Staff Publications

The issue of food insecurity affects millions of people in the United States every year. Often these people rely on soup kitchens, food banks, and shelters for proper meals, and these organizations often depend on donations to meet needs. One of the most limited food resources is meat. To help alleviate this problem, the U.S. Department of Agriculture Wildlife Services donates more than 60 tons of wild game (deer, moose, feral hogs, goats, geese, and ducks) to a variety of charitable organizations each year. Although commercially produced meat routinely undergoes screening for contaminants, potential exposure to environmental contaminants from eating …

Using Sterilization To Change Predation Rates Of Wild Coyotes:A Test Case Involving Pronghorn Fawns, Renee G. Seidler, Eric M. Gese, Mary M. Conner

United States Department of Agriculture Wildlife Services: Staff Publications

Surgical sterilization of coyotes (Canis latrans) reduced their predation rate on domesticsheep. We investigated whether sterilizing coyotes would similarly change coyote pre-dation rates on pronghorn antelope (Antilocapra americana) neonates. From May 2006 toMarch 2008, we radio-collared 71 pronghorn fawns to determine survival rates in south-east Colorado, USA. During the first year of the study, all coyotes were reproductively intact. During the second year, we surgically sterilized 15 coyotes from 10 packs in the southernhalf of the study area, while nine coyotes from seven packs in the northern half were givensham sterilizations (i.e., remained reproductively intact). In …

United States Department of Agriculture Wildlife Services: Staff Publications

White-tailed deer (Odocoileus virginianus) in Michigan, USA, are wildlife reservoirs of bovine tuberculosis (bTB) with documented spread to cattle. In vaccine efficacy trials, Mycobacterium bovis bacillus Calmette–Guerin (BCG) administered orally reduces colonization and bTB-associated lesions in white-tailed deer after experimental challenge with virulent M. bovis. The objective of this study was to develop and evaluate the palatability of a molasses-based bait for oral delivery of BCG to white-tailed deer. Relevant practical properties of the bait such as physical stability under various environmental conditions were evaluated, as well as palatability. Captive deer consumed baits within 3 h of …

Efficacy Of Plastic Mesh Tubes In Reducing Herbivory Damage By The Invasive Nutria (Myocastor Coypus) In An Urban Restoration Site, Trevor R. Sheffels, Mark D. Sytsma, Jacoby Carter, Jimmy D. Taylor Ii

United States Department of Agriculture Wildlife Services: Staff Publications

The restoration of stream corridors is becoming an increasingly important component of urban landscape planning, and the high cost of these projects necessitates the need to understand and address potential ecological obstacles to project success. The nutria (Myocastor coypus) is an invasive, semi-aquatic rodent native to South America that causes detrimental ecological impacts in riparian and wetland habitats throughout its introduced range, and techniques are needed to reduce nutria herbivory damage to urban stream restoration projects. We assessed the efficacy of standard Vexar® plastic mesh tubes in reducing nutria herbivory damage to newly established woody plants. The study …

United States Department of Agriculture Wildlife Services: Staff Publications

The restoration of eastern wild turkeys (Meleagris gallopavo silvestris; Viellot) within Wisconsin has successfully populated the central counties which account for 95% of American ginseng (Panax quinquefolius L.) production. In response to perceived and emerging conflicts, the Ginseng Board of Wisconsin, Inc. conducted producer surveys in March 2006 and 2012 to determine the extent and timing of wild turkey damage experienced among all Wisconsin ginseng producers, and the methods used to minimize wild turkey damage. We summarized 47 and 63 completed surveys in 2006 and 2012, respectively. Most survey respondents reported that wild turkeys were present and …

Examination Of Food Choice Motives: The Influence Of An Innovative, Interdisciplinary Learning Community Related To Environmental Sustainability, Kelly J. Billingsley

Theses and Dissertations

What and how much an individual eats largely defines his/her health. The most used dietary intervention models target individuals' concern for personal health, thereby undermining the interdisciplinary trajectory of the nutrition field. The purpose of this study was to compare the food choice motives of students enrolled in an interdisciplinary learning community (LCOM) to students enrolled in a non-integrated nutrition course and gain insight into student experiences with interdisciplinary nutrition education. A two-phase sequential mixed methods design was used. The first phase compared the personal health and ethical concern motives of the LCOM (n = 13) and non-integrated students (n …

Attachment Style And Perceived Stress In College Students, Jason Dorin

Theses and Dissertations

The purpose of this study was to examine the impact that attachment (as measured by an adult attachment measure) has on a college student's perceived stress levels.

The process of career planning and exploration the women described was consistent across the generations and included a period of …

Improving Disaster Response Collaboration Using Trans-Organization Development, Lacey M. Croco

Theses and Dissertations

In order to address the complex problems that arise as a result of a disaster, response organizations must know how to effectively collaborate. This study provides an initial exploration of the possible application of trans-organization development (TD) process for improving the effectiveness of disaster response collaborations. Through interviews and on online survey of emergency and disaster services practitioners (both professional and volunteer), this study concluded that while there is clear value in the concepts that the TD process proposes, it was inconclusive as to whether or not the process would improve the effectiveness of collaborations during disaster response. Based on …

Stress Relief In The Workplace, Jenny Gumm

Theses and Dissertations

The management of the psychological and physiological dimensions of stress can have significant effect on workplace productivity. Yet, stress as a universal human phenomenon is often downplayed or misunderstood by both employees and organizations. This study looked at the effects of stress on the workplace from both an individual and an organizational perspective. An exploratory mixed methods design was used to test the efficacy and potential benefits of providing employees with tools to help them better manage their stress. The three components of Hatha Yoga: breath, movement, and mediation were introduced on site to the employees of a small start-up …

Self-Concept And Recovery : The Effects Of Stigma On Survivors Of Sex Trafficking, Pamela Alquitran Counts

Theses and Dissertations

Survivors of sex trafficking often face complex and complicated situations upon exiting. Stigmatization is a barrier that challenges efforts to heal and rebuild relationships. This study aimed to identify how survivors of trafficking understand the stigma from their families and communities, and how this experience of stigma affects their overall sense of self-concept and belief in their ability to cope and overcome their predicament. Results from interviews with six survivors of trafficking indicate that survivors carry multiple layers of stigma that are worsened by the addition of stigma associated with being trafficked for prostitution. Negative evaluations about the woman maintain …

Impact Of Run-Off Coefficients On Urban Drainage Design, Ross O'Sullivan

Theses

This study assesses the impacts that runoff coefficients have on an urban drainage design. The first part of the report reviews how drainage design is carried out. This assesses the traditional hand calculations method, where eharts and graphs are used, versus the more modem approach of using a computer modelling system such as WinDes. Both approaches were reviewed, as both will be used to design drainage systems at a further stage in the project. The objective of this projeet is to see how runoff eoefficients impact on urban drainage design. The methodology used to determine this, is to test six …

Characterisation Of The Enzybiotic Potential Of Selected Staphylococcus Aureus Bacteriophages, Ruth Keary

Theses

The work presented in this thesis focuses on harnessing the bactericidal potential of bacteriophage (phage) encoded peptidoglycan hydrolase enzymes to combat the significant pathogen Staphylococcus aureus. In order to identify novel peptidoglycan hydrolases lytic against S. aureus, the complete genomes of two staphylococcal temperate Siphoviridae bacteriophages, DW2 and CSl, were sequenced and annotated. Screening of these genomes identified genes for several putative peptidoglycan hydrolases including two endolysins and three virion-associated peptidoglycan hydrolases. The identification of putative genes relating to virulence and host fitness lends to the understanding of the role played by such temperate phages in the evolution of this …

A Novel Waveform For Emergency Services Mobile Ad-Hoc Networks : The Link Layer Perspective, Sebastian Helmle

Theses

Existing wireless communication systems of emergency services mainly enable ordinary unicast or broadcast voice communications. The increasing demand for data services such as messaging, file transfer, maps, etc requires those long-range communication systems to provide higher data rates while maintaining robustness against link failures. In this thesis, various aspects of a link layer design specifically for narrowband mobile ad-hoc networks (MANETs) that are targeted at emergency services are investigated.

The major aspect of this thesis is the optimisation of a time division multiple access (TDMA) design considering both efficient and reliable multicast resource reservation. An approach to mathematically describe a …

Theses

Campylobacter ureolyticus has been identified in a large proportion of diarrhoeal samples from patients in Ireland. However, the source of human infections has not been established and little is currently known about the potential reservoirs of C. ureolyticus in nature.

The aim of this project was to investigate a range of environmental and animal samples for the presence of this emerging pathogen using a molecular approach, to support the hypothesis of its zoonotic origin.

During the study, C. ureolyticus was detected in 30 out of 1,254 (2.4%) human diarrheic samples and isolated from 11 patients, describing, to the best of …

Evaluation Of Ireland’S Potential To Expand Its Hydro Electrical Power Facilities Through The Construction Of A Seawater Pumped Hydro Energy Storage Scheme, James Herley

Theses

The National Renewable Energy Action Plan for Ireland has detailed that 40% of Irelands total energy consumption from the electricity sector must come from renewable sources by 2020. In 2012 this figure was at 11.4%, it is unlikely these targets will be met by 2020. The important role that hydro power can play in achieving these targets was examined. Research into hydropower in general was carried out in order to attain an understanding of the principles and terminology used. Many traditional hydro schemes have been previously developed in Ireland. However due to increased population, there are no longer suitable locations …

Investigation Of Pyrrolizidine Alkaloids In Foods Using Liquid Chromatography Mass Spectrometry, Caroline Griffin

Theses

Pyrrolizidine Alkaloids (PAs) are known plant toxins which can cause hepatic veno-occlusive disease (HVOD) in both humans and livestock when ingested. Although PAs are primarily known for their hepatotoxicity they also induce genotoxicity, carcinogenicity and pneumotoxicity. PAs are consumed through plants as food, for medicinal purposes, or as contaminants of agricultural crops. Aside from ingesting the plants directly PA exposure may occur through the consumption of honey produced by bees that visit PA-containing plants or by drinking milk produced by animals that have consumed PA-containing plants. Possible PA contamination in our food chain is a potential health risk.

To assess …

The Development Of Liquid Chromatography Mass Spectrometry Methods For The Analysis Of Cyanobacterial Toxins In Environmental Freshwaters, Brian Anthony Dineen

Theses

Cyanobacteria, also known as blue-green algae, are a common component of many freshwater and marine ecosystems and have a potential to produce several different classes of biotoxins. The most common class of cyanobacterial toxins are the microcystins (MCs) and cylindrospermopsins (CYLs). MCs are cyclic heptapeptides that display potent hepatotoxicity and are tumour promoters. CYLs are alkaloids that are cytotoxic and can cause illness and display hepatotoxic effects in animals and humans. Worldwide, these toxins have caused fatal poisonings to animals, birds and fish. Several incidents of human intoxications have been reported and the presence of these toxins in environmental waters …

Why The Buffett-Gates Giving Pledge Requires Limitation Of The Estate Tax Charitable Deduction, Edward A. Zelinsky

Articles

The Buffett-Gates Giving Pledge, under which wealthy individuals promise to leave a majority of their assets to charity, is an admirable effort to encourage philanthropy. However, the Pledge requires us to confront the paradox that the federal estate tax charitable deduction is unlimited while the federal income tax charitable deduction is capped. If a Giving Pledger leaves his wealth to charity, the federal fisc loses significant revenue since the Pledger thereby avoids federal estate taxation as charitable bequests are deductible without limit for federal estate tax purposes. Despite its laudable qualities, the Giving Pledge is a systematic (albeit inadvertent) threat …

The Irish Sport Horse Abroad: The Role Of Public Relations In Promoting An International Brand, Marianne Van Pelt

Theses

This thesis uses a case study approach to explore the role of public relations in promoting an international brand. This thesis attempts to determine whether public relations can contribute significantly to the promotion of an established international brand. This thesis looks at whether the people in the organisation formally responsible for promoting the Irish Sport Horse brand have a stated goal of promoting the brand, a clear intention of promoting the brand through public relations tactics, and whether find these tactics successful. The thesis also looks at the views of opinion makers within the industry to try to verify the …

The Effects Of "Stress Inoculation" On Anxiety-Related Behaviors In A Rodent Model, Rebecca Ruth Clouse

Master's Theses

Problem. Humans may face psychological stressors in their everyday life due to their ability to contemplate future events. While long-term stress exposure may be detrimental to health, this study examines the possibility that exposure to unpredictable/controllable, moderate stress may cause resilience against future stressors. This is referred to as the "stress inoculation hypothesis." The effects of unpredictable/controllable stress can be illustrated as a rightward shift in an inverted U-shaped curve, where optimal performance (the top of the curve) can be maintained at higher stress levels. -- Method. Thirty-three male Sprague-Dawley rats were tested on the elevated-plus maze (EPM) for trait …

Replication Of Known Dental Characteristics In Porcine Skin: Emerging Technologies For The Imaging Specialist, L. Thomas Johnson, Thomas W. Radmer, Dean C. Jeutter, Gary L. Stafford, Joseph Thulin, Thomas Wirtz, George Corliss, Kwang Woo Ahn, Alexis Visotky, Ronald L. Groffy

School of Dentistry Faculty Research and Publications

This study demonstrates that it is sometimes possible to replicate patterns of human teeth in pig skin and determine scientifically that a given injury pattern (bite mark) correlates with the dentitions of a very small proportion of a population dataset, e.g., 5 percent or even 1 percent. The authors recommend building on the template of this research with a sufficiently large database of samples that reflects the diverse world population. They also envision the development of a sophisticated imaging software application that enables forensic examiners to insert parameters for measurement, as well as additional methods of applying force to produce …

Are Damages Different? Bivens And National Security, Andrew Kent

Faculty Scholarship

Litigation challenging the national security actions of the federal government has taken a seemingly paradoxical form in recent years. Prospective coercive remedies like injunctions and habeas corpus (a kind of injunction) are traditionally understood to involve much greater intrusions by the judiciary into government functioning than retrospective money damages awards. Yet federal courts have developed and strictly applied doctrines barring Bivens damages actions against federal officials because of an asserted need to preserve the prerogatives of the political branches in national security and foreign affairs. At the same time, the courts have been increasingly assertive in cases involving coercive remedies, …

Politics And Aesthetics: Partitions And Partioning In Contemporary Art, Jonathan Owen Clark, Joao Lima Duque

Contemporary Aesthetics (Journal Archive)

Jacques Rancière defined the “distribution of the sensible” as the effect of a type of aesthetico-political decision-making that creates a partitioning of the realm of the perceivable in relation to both art and society. The artworld itself constructs its own particular types of curatorial partitioning: between “art” and “non-art,” between “dominant, residual, and emergent,” and between “mainstream” and “periphery.” This essay examines certain “boundary effects” that develop as a result of the act of the partitioning itself and closely examines what arguably are two new categories in contemporary art: “crossover” and “interventionist.” Both categories have a certain relationship to a …
