One Health In Action: Reducing Feral Swine Damage And Disease, Sarah N. Bevins, Alan B. Franklin

United States Department of Agriculture Wildlife Services: Staff Publications

As an invasive species, feral swine (Sus scrofa) are a classic example of a species that can profoundly influence ecological communities and ecosystems. They alter environments through a suite of well-known traits: rooting behaviors that alter soil properties and disturb plant communities; a generalist diet that can encompass seeds, crops, and animals; a rapid reproduction rate that can result in explosive population growth; and an adaptable biology that allows them to thrive in a range of habitats and climates. Along with these more familiar traits of an aggressive invasive species, feral swine can also reservoir and transmit a …

Characteristics Of White-Tailed Deer Visits To Cattle Farms: Implications For Disease Transmission At The Wildlife-Livestock Interface, Are R. Berentsen, Ryan S. Miller, Jennifer L. Malmberg, Mike R. Dunbar

United States Department of Agriculture Wildlife Services: Staff Publications

Bovine tuberculosis (bTB) is endemic in free-ranging white-tailed deer (Odocoileus virginianus) in MI, USA. Currently, the rates of farm visitation by deer and co-use of forage resources by cattle and deer are poorly understood. To evaluate the extent deer and livestock may share forage resources, we investigated farm, yard, and cattle-use area visitation by white-tailed deer and compared visitation with common livestock management practices. We fitted 25 female white-tailed deer near the bTB-infected zone in Michigan's Lower Peninsula with global positioning system collars. Livestock management practices associated with farm visitation included presence of confined feeding pastures, number of cattle water …

The number of pathogens known to infect humans is ever increasing. Whether such increase reflects improved surveillance and detection or actual emergence of novel pathogens is unclear. Nonetheless, infectious diseases are the second leading cause of human mortality and disability-adjusted life years lost worldwide [1,2]. On average, three to four new pathogen species are detected in the human population every year [3]. Most of these emerging pathogens originate from nonhuman animal species. Zoonotic pathogens represent approximately 60% of all known pathogens able to infect humans [4]. Their occurrence in humans relies on the human-animal interface, defined as the continuum of …

Movement Characteristics Of American Beavers (Castor Canadensis), Lance F. Mcclintic, Guiming Wang, Jimmy D. Taylor Ii, Jeanne C. Jones

United States Department of Agriculture Wildlife Services: Staff Publications

Physiological states and foraging behaviors may shape movement patterns of animals. Optimal foraging theory and what we term the deliberate movement hypothesis predict that, to reduce predation risk, central place foragers should move faster with smaller turning angles the further they are from their central place. The complementary bimodal foraging trip hypothesis predicts that the distribution of foraging distances exhibited by central place foragers should be bimodal due to a trade-off between provisioning offspring and self-feeding. We used radio-telemetry to test these hypotheses for American beavers (Castor canadensis) in northern Alabama, United States. American beavers moved faster with …

Behavioral Traits And Airport Type Affect Mammal Incidents With U.S. Civil Aircraft, Kristin B. Schwarz, Jerrold L. Belant, James A. Martin, Travis L. Devault, Guiming Wang

United States Department of Agriculture Wildlife Services: Staff Publications

Wildlife incidents with aircraft cost the United States (U.S.) civil aviation industry >US$1.4 billion in estimated damages and loss of revenue from 1990 to 2009. Although terrestrial mammals represented only 2.3 % of wildlife incidents, damage to aircraft occurred in 59 % of mammal incidents. We examined mammal incidents (excluding bats) at all airports in the Federal Aviation Administration (FAA) National Wildlife Strike Database from 1990 to 2010 to characterize these incidents by airport type: Part-139 certified (certificated) and general aviation (GA). We also calculated relative hazard scores for species most frequently involved in incidents. We found certificated airports had …

European Starling Feeding Activity On Repellent Treated Crops And Pellets, Shelagh K. Tupper, Scott J. Werner, James C. Carlson, Susan E. Pettit, John C. Wise, Catherine A. Lindell, George M. Linz

United States Department of Agriculture Wildlife Services: Staff Publications

The varied diet of European starlings (Sturnus vulgaris L.) can present challenges when working with starlings in experimental testing and holding situations and should be taken into account when testing repellents applied to food. Our purpose was to evaluate an anthraquinone-based repellent (Arkion Life Sciences, New Castle, DE, USA; active ingredient 50% 9,10-anthraquinone; hereafter anthraquinone) and SucraShield^TM (Natural Forces, Davidson, NC, USA; active ingredient 40% sucrose octanoate esters) repellent for non-lethal protection of specialty crops (i.e., fruit, sweet corn) and grains. Our objectives were to evaluate (1) laboratory efficacy of anthraquinone applied topically to blueberries and sweet …

An Efficacy Test Of Cholecalciferol Plus Diphacinone Rodenticide Baits For California Voles (Microtus Californicus Peale) To Replace Ineffective Chlorophacinone Baits, Gary W. Witmer, Rachael S. Moulton, Roger A. Baldwin

United States Department of Agriculture Wildlife Services: Staff Publications

California voles cause damage to pastures and rangelands, orchards and nurseries, and a wide variety of field crops, including artichokes. The anticoagulant rodenticides (chlorophacinone and diphacinone) typically used for voles are becoming less effective in controlling their populations. Consequently, there is a need to identify new rodenticides that will have a high efficacy on California voles so that agricultural production losses to rodents can be substantially reduced. We tested a new formulation containing two active ingredients (cholecalciferol and diphacinone) as a control method for California voles. Both a pelleted bait and an oil-coated artichoke bract bait were very palatable and …

Responses By Wild House Mice (Mus Musculus) To Variousstimuli In A Novel Environment, Gary W. Witmer, Nathan P. Snow, Rachael S. Moulton

United States Department of Agriculture Wildlife Services: Staff Publications

House mice (Mus musculus) pose a threat to the native flora and fauna on islands, and cancause significant damage wherever they have been introduced. Methods used to eradicateinvasive rodents, like house mice, at high population densities may not be appropriate forintercepting them at lower densities. A better understanding of the immediate behavior ofhouse mice when first introduced to a novel environment would help managers developeffective biosecurity techniques to protect against new invasions. To address this problem,we conducted a controlled laboratory experiment that simulated an invasion by wild housemice into a novel environment. We quantified and compared the immediate behaviors …

Evaluating The Clinical And Physiological Effects Of Long Term Ultraviolet B Radiation On Guinea Pigs (Cavia Porcellus), Megan K. Watson, Adam W. Stern, Amber L. Labelle, Stephen Joslyn, Timonthy M. Fan, Katie Leister, Micah Kohles, Kemba Marshall, Mark A. Mitchell

School of Veterinary and Biomedical Sciences: Faculty Publications

Vitamin D is an important hormone in vertebrates. Most animals acquire this hormone through their diet, secondary to exposure to ultraviolet B (UVB) radiation, or a combination thereof. The objectives for this research were to evaluate the clinical and physiologic effects of artificial UVB light supplementation on guinea pigs (Cavia porcellus) and to evaluate the long-term safety of artificial UVB light supplementation over the course of six months. Twelve juvenile acromelanic Hartley guinea pigs were randomly assigned to one of two treatment groups: Group A was exposed to 12 hours of artificial UVB radiation daily and Group B …

Virtual Water, Water Scarcity, And International Trade Law, Edith Brown Weiss, Lydia Slobodian

Georgetown Law Faculty Publications and Other Works

We are facing a fresh water crisis during this century. In less than two decades, by 2030, the requirements for fresh water are expected to exceed the currently available and accessible fresh water supplies by 40%. Many countries are expected to be water stressed later in this century; some areas of the world already are. Some people may even lack water to meet basic human needs, such as drinking, washing, and sanitation. In rural areas in certain regions, people may lack water to grow good food crops, even for their own consumption. This has major implications for the welfare of …

A Possible Solution To The Problem Of Diminishing Tribal Sovereignty, Hope M. Babcock

Georgetown Law Faculty Publications and Other Works

The capacity of Indian tribal sovereignty to protect tribes from outside encroachment and interference has steadily diminished from when the concept was first enunciated in the nineteenth century in the Marshall Indian Law Trilogy. This article assumes as a working premise that only bringing tribes into the Constitution as co-equal sovereigns will end the attrition. The article examines how this might happen, either through creative interpretation of existing constitutional text or by amending the Constitution. Each of these proposals is examined to see if it empowers tribes to manage their futures more effectively, is capacious enough to include the vast …

The Judicial Duty To Scrutinize Legislation, Randy E. Barnett

Georgetown Law Faculty Publications and Other Works

The Declaration of Independence famously declared, “[w]e hold these truths to be self-evident, that all Men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the Pursuit of Happiness.” It then affirmed “[t]hat to secure these Rights, Governments are instituted among Men, deriving their just Powers from the Consent of the Governed.” This last sentence has proven to be problematic.

If “consent of the governed” means the consent of a majority of “We the people,” then the “consent of the governed” can be used to violate the unalienable …

Place, Not Race: Affirmative Action And The Geography Of Educational Opportunity, Sheryll Cashin

Georgetown Law Faculty Publications and Other Works

The discourse in America about segregation is dishonest. On the surface, we pretend that the values of Brown v. Board of Education have been met, although most of us know in our hearts that the current system of public education betrays those values. In this essay, I reflect on how residual, defacto segregation and the stratified architecture of opportunity in our nation contribute to the achievement gap that has made race-based affirmative action necessary. Despite the Supreme Court's compromise decision in Fisher v. Texas, affirmative action is on life support. As this essay goes to print, the Supreme Court has …

Responding To Infant Sleep-Related Crying : A Theoretical Exploration Of Caregiver Response From Attachment And Object Relations Perspectives, Casey L. Zandoná

Theses, Dissertations, and Projects

How to respond to infant sleep-related crying is a ripe debate in much of the current parenting literature. This theoretical thesis explores how certain caregiver responses affect infants' psychological development. Particular attention is paid to the popular sleep-training technique—letting a baby "Cry It Out"—as there is an alarming lack of consideration within empirical and theoretical literature of the psychological impact of this parenting strategy on an infant. This thesis begins with an overview of current empirical research on infant sleep and crying behavior, and proceeds to include an in-depth look at attachment and object relations (mostly Winnicottian) theories, specifically in …

Decorating The Structure: The Art Of Making Human Law, Brian Mccall

Faculty Articles

This article continues to develop the theme of law as architecture begun in two published articles, The Architecture of Law: Building Law on a Solid Foundation, the Eternal and Natural Law and Consulting the Architect when Problems Arise: The Divine Law. Having considered the foundation and framework of human law, this article turns to the decoration of the structure through the craft of human law making. It examines the process whereby the natural law is determined in particular political communities. Human law is the craft of particularizing the general principles of natural law in a community’s laws. It relies on …

How To Be An Authentic Indian, M. Alexander Pearl

Faculty Articles

The mascot and team name of the Washington, D.C. professional football team is making headlines. What do Authentic Indians really think about it? This essay clears the air by replacing the liberal media talking points with an actual viewpoint from Indian Country. This perspective gives an inside view into the significant efforts to maintain longstanding traits of “Indian-ness” against an onslaught of political correctness gone mad.

Nonprofits, Speech, And Unconstitutional Conditions, Lloyd Hitoshi Mayer

Journal Articles

This Article proposes a new constitutional framework for approaching the issue of speech-related conditions on government funding received by nonprofits and demonstrates the application of this framework by applying it to the disputes that have reached the Supreme Court in this area. It argues that speech rights are generally inalienable as against the government under the First Amendment, and therefore any abridgement of such rights by the government – whether direct or indirect – is subject to strict scrutiny. As a result, the government is not permitted to buy an organization’s speech (or silence) absent a compelling governmental interest in …

Trans-Personal Procedures, Roger Michalski

Faculty Articles

Recent court decisions have reignited a national debate about corporate personhood. This debate recognizes that the legal status of artificial persons is of great importance to the fabric of society, law, and politics. Questions about the status of artificial persons are typically raised in the context of substantive law, where corporate personhood has triggered strong reactions and important scholarship. But there is another, completely neglected side to this debate. The status of artificial entities is not solely negotiated in the context of substantive law. Procedure, similarly, must also choose whether to treat natural and artificial entities alike or not. This …

Institutional Autonomy And Constitutional Structure, Randy J. Kozel

Journal Articles

This Review makes two claims. The first is that Paul Horwitz’s excellent book, "First Amendment Institutions," depicts the institutionalist movement in robust and provocative form. The second is that it would be a mistake to assume from its immersion in First Amendment jurisprudence (not to mention its title) that the book's implications are limited to the First Amendment. Professor Horwitz presents First Amendment institutionalism as a wide-ranging theory of constitutional structure whose focus is as much on constraining the authority of political government as it is on facilitating expression. These are the terms on which the book's argument — and, …

Pandemic Disease, Biological Weapons, And War, Laura K. Donohue

Georgetown Law Faculty Publications and Other Works

Over the past two decades, concern about the threat posed by biological weapons has grown. Biowarfare is not new. But prior to the recent trend, the threat largely centered on state use of such weapons. What changed with the end of the Cold War was the growing apprehension that materials and knowledge would proliferate beyond industrialized states’ control, and that “rogue states” or nonstate actors would acquire and use biological weapons. Accordingly, in 1993 senators Samuel Nunn, Richard Lugar, and Pete Dominici expanded the Cooperative Threat Reduction Program to assist the former Soviet republics in securing biological agents and weapons …

“I’M A Lawyer, Not An Ethnographer, Jim”: Textual Poachers And Fair Use, Rebecca Tushnet

Emotional Abuse : The Subjective Experience Of Professionals And The Obstacles To Prevention And Intervention, Rachel H. Flichtbeil

Theses, Dissertations, and Projects

The purpose of this study was to explore the subjective experience of the professionals in the Denver/Boulder area working with emotional abuse that occurs between children and their caretakers and to examine the obstacles they experience to more effective prevention and intervention of emotional abuse. Emotional abuse is a widespread and damaging social problem that is often ignored or minimized by the legal system, the child welfare system and the mental health system (Doyle, 1997; Glaser, 2011; Marshall, 2012). This study interviewed 12 key informants from the mental health system, the child welfare system and the legal system and included …

The Effect Of Chilling On Diapause And Development Of Washington State Apple Maggot Rhagoletis Pomonella (Walsh) (Diptera: Tephritidae), Nathan J. Lehrman

All Master's Theses

The influence of holding temperatures and chilling periods on diapausing R. pomonella (apple maggot) pupae were the focus of the study. Apples were collected from Pierce and Lewis County in Washington State. After collecting R. pomonella from the fruit, the pupae were chilled at 3°C for 0, 1, 2, 5, 10, 15, 20, 25 or 30 weeks, then allowed to emerge at either 20°C or 26°C. The insects were then monitored for survivorship and eclosion. Rhagoletis pomonella would emerge fastest when held at 26°C and developed on average in fewer degree days (284±252 degree days). However, more adults emerged after …

Women And Evangelical Individualism, Danielle C. Kuehn

All Master's Theses

By comparing the way male ministers presented their faith in gendered terms during the First Great Awakening to the responses of women who embraced their doctrine, the study examines whether women gained autonomy from the evangelical emphasis on individual choice and responsibility. Primary sources were the foundation for the research and included sermons from the most prominent ministers of the era, Jonathan Edwards and George Whitefield. Journals of women evangelicals were invaluable resources providing first hand accounts of the implications of gender roles and religious ideology in evangelicals' lives during and following the Great Awakening. The primary documents studied here …

A Proto-Architecture For Innate Directionally Selective Visual Maps., Sv Adams, Cm Harris

School of Psychology

Self-organizing artificial neural networks are a popular tool for studying visual system development, in particular the cortical feature maps present in real systems that represent properties such as ocular dominance (OD), orientation-selectivity (OR) and direction selectivity (DS). They are also potentially useful in artificial systems, for example robotics, where the ability to extract and learn features from the environment in an unsupervised way is important. In this computational study we explore a DS map that is already latent in a simple artificial network. This latent selectivity arises purely from the cortical architecture without any explicit coding for DS and prior …

Mechanism Of GabaB Receptor-Activated Increases In L-Type Calcium Current In The Neonatal Mammalian Hippocampus, Andrew S. Karls

Dissertations (1934 -)

Activation of the metabotropic GABA_B receptor has most commonly been demonstrated to produce inhibitory effects on neurons, including the attenuation of voltage-dependent calcium current. However, during the early neonatal period in mammalian development, activation of GABA_B receptors leads to an enhancement of calcium current through a specific class of calcium channels, termed L-type channels, (because they conduct Long-lasting current) . This response peaks at 7 days postnatal, and is only demonstrated in a subset of cells. In the work presented here, the signal transduction pathway of GABA_B receptor-mediated increase of L-type current is described.

GABA_B receptors …

Academic Achievement And Perceptions Of Nature Appreciation, Environmental Awareness, And Well-Being Of Participants In Sully's Hill Nature Education Program, Jared Duane Schlenker

Theses and Dissertations

Experiential and hands-on learning are important for any effective educational environment, and when combined with natural elements that can stimulate students' senses to enhance their learning, these educational methods may have a profound effect (Louv, 2008). The Sully's Hill Nature Education Program (SHNEP) allows fifth-grade students at Central Middle School in Devils Lake, North Dakota, to learn in an outdoor setting.

The purpose of this study was to determine if a relationship exists between Devils Lake fifth graders and sixth graders who participate(d) in the Sully's Hill Nature Education Program (SHNEP), and those students who have not participated in the …
