Influence Of Vitamin K-Rich Plant Foods On Anticoagulant Baiting Efficacy In Wild House Mice, Wild Norway Rats, And Wild Black Rats, G. W. Witmer, P. W. Burke

United States Department of Agriculture Wildlife Services: Staff Publications

Rodents introduced to islands have caused the extinction of many species of animals. Anticoagulant rodenticides are relied on to eradicate rodents from these islands, but if the rodents are eating plant materials that contain high amounts of vitamin K (the antidote to anticoagulants) anticoagulant rodenticides may not be effective. In a laboratory trial, individually caged Noway Rats Rattus norvegicus, Black Rats R. raffus and House Mice Mus musculus were fed fresh plant material high in vitamin K (Collards [0.62 mg vitamin K per 100 g] and Brussels Sprouts [0.19 mg vitamin K per 100 g]) for a period of …

West Nile Virus Detection In Nonvascular Feathers From Avian Carcasses, Nicole M. Nemeth, Ginger R. Young, Kristen L. Burkhalter, Aaron C. Brault, William K. Reisen, Nicholas Komar

United States Department of Agriculture Wildlife Services: Staff Publications

West Nile virus (WNV) is a public health threat and has caused the death of thousands of North American birds. As such, surveillance for WNV has been ongoing, utilizing numerous biological specimens and testing methods. Nonvascular (i.e., fully grown) feathers would provide a simple method of collection from either dead or live birds of all ages and molt cycles, with presumably less biosafety risk compared with other specimen types, including feather pulp. The current study evaluates WNV detection in nonvascular feathers removed from naturally infected avian carcasses of several species groups. Feathers of corvid passeriforms had the highest sensitivity of …

Pathogenesis And Epidemiology Of Brucellosis In Yellowstone Bison: Serologic And Culture Results From Adult Females And Their Progeny, Jack C. Rhyan, Keith Aune, Thomas Roffe, Darla Ewalt, Steve Hennager, Tom Gidlewski, Steve Olsen, Ryan Clarke

United States Department of Agriculture Wildlife Services: Staff Publications

Our objective in this prospective study was to determine the natural course of Brucella abortus infection in cohorts of seropositive and seronegative, female bison (Bison bison) and their offspring in Yellowstone National Park (YNP) for 5 yr. We collected specimens from 53 adult females and 25 calves at least once and from 45 adults and 22 calves more than once. Annual seroconversion rates (negative to positive) were relatively high (23% for calves and juvenile bison, 6% in the total sample of adult female bison in our study, and 11% in the adult females that began the study as …

Laying The Foundation For Progress Research In Family, Couple, And Individual Therapy: The Development And Psychometric Features Of The Initial Systemic Therapy Inventory Of Change, William M. Pinsof, Richard E. Zinbarg, Jay L. Lebow, Lynne M. Knobloch-Fedders, C. Emily Durbin, Anthony L. Chambers, Tara A. Latta, Eli Karam, Jacob Z. Goldsmith, Greg Friedman

Psychology Faculty Research and Publications

This article details the development and methodological characteristics of the Systemic Therapy Inventory of Change (STIC), the first measurement system designed to assess change in family, couple, and individual therapy from a multisystemic and multidimensional perspective. The article focuses specifically on the developmental process that resulted in the five valid and reliable scales that comprise the core measure of the system, the INITIAL STIC, which is administered to clients just before beginning therapy. The scales focus on five systemic domains: individual adult, family of origin, couple, family, and individual child. This article describes the five system scales, the results of …

An Exploratory Study Of High School Students. Conceptions Of Atomic And Cellular Structure And Relationships Between Atoms And Cells, Elizabeth Anne Edwards Roland

University of Kentucky Doctoral Dissertations

Constructivist learning theory is based upon the tenets that students come to learning experiences with prior knowledge and experiences that the learner will choose from to make sense of the present situation. This leads to a mixture of understandings among students. This study proposed to reveal students‟ understanding of atomic structure and cell structure as well as the relationships between atoms and cells.

High school students from one private school participated in a paper-and-pencil test to uncover conceptual understanding and content knowledge of atoms and cells. The 120 participants were from grades: 9 (13m, 15f), 10 (9m, 20f), 11 (21m, …

Satisfaction Assessment Of Textual Software Engineering Artifacts, Elizabeth Ashlee Holbrook

University of Kentucky Doctoral Dissertations

A large number of software projects exist and will continue to be developed that have textual requirements and textual design elements where the design elements should fully satisfy the requirements. Current techniques to assess the satisfaction of requirements by corresponding design elements are largely manual processes that lack formal criteria and standard practices. Software projects that require satisfaction assessment are often very large systems containing several hundred requirements and design elements. Often these projects are within a high assurance project domain, where human lives and millions of dollars of funding are at stake. Manual satisfaction assessment is expensive in terms …

The Kosovo Crisis: A Dostoievskian Dialogue On International Law, Statecraft, And Soulcraft, Antonio F. Perez, Robert J. Delahunty

Scholarly Articles

The secession of Kosovo from Serbia in February 2008 represents a stage in the unfolding of a revolution of "constitutional" dimensions in International Law that began with NATO's 1999 intervention in Kosovo against Serbia. NATO's intervention called into question the authority and viability of U.N. Charter system for maintaining international peace. Likewise, the West's decision in 2008 to support Kosovo's secession from Serbia dealt a further blow to the central post-War legal rules and institutions for controlling and mitigating Great power rivalry. Russia's later support for South Ossetia's secession from Georgia demonstrated the potential that the Kosovo precedent has for …

Culpability In Creating The Choice Of Evils, Marc O. Degirolami

Scholarly Articles

Can an actor justify criminal conduct when he was criminally culpable in creating the conditions making it necessary? Virtually every American jurisdiction answers that he cannot and bars the necessity defense under those circumstances. Whereas many scholars have condemned that response, this Article takes the very different view that the exclusion of the defense for purposeful, knowing, and reckless criminal conduct that directly causes the conditions leading to the allegedly justified act represents a sound retributivist check on what is an otherwise cruder evaluation of whether conduct is socially valuable, worthy of praise, or, in a word, justified. Criminal "created …

Advocating For Sri Lankan Migrant Workers: Obstacles And Challenges, Michele Ruth Gamburd

Anthropology Faculty Publications and Presentations

Nearly a million Sri Lankan women labor as migrant workers, the vast majority in the Gulf Cooperation Council (GCC) countries in West Asia. They are poorly paid and vulnerable to a wide variety of exploitative labor practices at home and abroad. Despite the importance of worker remittances to the national economy, and in spite of Sri Lanka’s history of organized labor and active political participation, migrants have received only anemic support from the state, labor unions, feminist organizations, and migrant-oriented nongovernmental organizations (NGOs). The article contextualizes Sri Lankan migration within larger-scale economic dynamics (such as global capitalist policies and processes) …

Finding And Dating Cathlapotle, Kenneth M. Ames, Elizabeth A. Sobel

Anthropology Faculty Publications and Presentations

The people of the Cathlapotle town played a significant role in the fur trade era history of the Lower Columbia River, including Lewis and Clark’s visit on March 29th, 1806. Archaeologists and others have sought the town’s location for years. Long-term research has established that archaeological site 45CL1 on the US Fish and Wildlife Refuge near Ridgefield, Washington is Cathlapotle. This determination is based on the close match between site details with various ethnohistoric accounts of Cathlapotle. The site was occupied by ca. AD 1450 and probably moved there from another nearby location. It was abandoned sometime in the 1830s …

Rees Products Of Posets And Inequalities, Tricia Muldoon Brown

University of Kentucky Doctoral Dissertations

In this dissertation we will look at properties of two different posets from different perspectives. The first poset is the Rees product of the face lattice of the n-cube with the chain. Specifically we study the Möbius function of this poset. Our proof techniques include straightforward enumeration and a bijection between a set of labeled augmented skew diagrams and barred signed permutations which label the maximal chains of this poset. Because the Rees product of this poset is Cohen-Macaulay, we find a basis for the top homology group and a representation of the top homology group over the symmetric …

The Interaction Between Personality Traits And Contextual Disadvantage On Criminal Behavior: A Longitudinal Study Of High Risk-Females, Lauren C. Gudonis

University of Kentucky Doctoral Dissertations

This investigation examined several dimensions of personality functioning in a longitudinal sample of females. These data are part of an existing project evaluating female development across 3 different time points starting in adolescence and transitioning into adulthood. Subjects were categorized into a clinical group (females with a high degree of psychiatric comorbidity) and a normal control group. All participants were initially recruited when they were between 14-18 years of age, and were followed up twice when they were 19-23, and 24-28. In an attempt to explore possible heterogeneity in personality trait development, the research is presented as three separate studies …

Micro-Fabricated Hydrogen Sensors Operating At Elevated Temperatures, Chi Lu

University of Kentucky Doctoral Dissertations

In this dissertation, three types of microfabricated solid-state sensors had been designed and developed on silicon wafers, aiming to detect hydrogen gas at elevated temperatures. Based on the material properties and sensing mechanisms, they were operated at 140°C, 500°C, and 300°C. The MOS-capacitor device working at 140°C utilized nickel instead of the widely-used expensive palladium, and the performance remained excellent. For very-high temperature sensing (500°C), the conductivity of the thermally oxidized TiO₂ thin film based on the anodic aluminum oxide (AAO) substrate changed 25 times in response to 5 ppm H₂ and the response transient times were just …

Eigenvalue Inequalities For A Family Of Spherically Symmetric Riemannian Manifolds, Julie Miker

University of Kentucky Doctoral Dissertations

This thesis considers two isoperimetric inequalities for the eigenvalues of the Laplacian on a family of spherically symmetric Riemannian manifolds. The Payne-Pólya-Weinberger Conjecture (PPW) states that for a bounded domain Ω in Euclidean space Rⁿ, the ratio λ1(Ω)/λ0(Ω) of the first two eigenvalues of the Dirichlet Laplacian is bounded by the corresponding eigenvalue ratio for the Dirichlet Laplacian on the ball B_Ωof equal volume. The Szegö-Weinberger inequality states that for a bounded domain Ω in Euclidean space Rⁿ, the first nonzero eigenvalue of the Neumann Laplacian μ1(Ω) is maximized on the ball B_{Ω …}

Content Relevance Centric Theory: An Investigation Of Content Relevance's Ability To Predict Learning Outcomes In A Training Environment, E. Patrick Leddin

University of Kentucky Doctoral Dissertations

After three decades of research, instructional communication scholars find themselves facing several key challenges. These range from an overemphasis in past studies on variable-analytic, atheoretical research to a lack of connection to learning outcomes. Many in the field contend that the time has come for instructional communication researchers to define instructional communication theories, test hypotheses, tie research efforts to learning outcomes, and clarify key terms. The present study addressed these shortcomings by proposing the Content Relevance Centric Theory and testing related hypotheses.

The research occurred in a professional training environment and involved the use of a modified content relevance instrument …

Avian Visual System Configuration And Behavioural Response To Object Approach, Bradley F. Blackwell, Esteban Fernandez-Juricic, Thomas W. Seamans, Tracy Dolan

United States Department of Agriculture Wildlife Services: Staff Publications

Antipredator behaviour theory provides a framework to understand the mechanisms behind human– wildlife interactions; however, little is known about the role of visual systems in the responses to humans. We quantified responses of brown-headed cowbirds, Molothrus ater (Boddaert), and mourning doves, Zenaida macroura (Linnaeus), to object approach (a ground-based vehicle) and vehicle lighting regimen, and we examined two visual properties (visual acuity and visual fields) that could influence antipredator behaviour. Brown-headed cowbird groups exposed to vehicle approach and constant illumination of the vehicle-mounted lamp showed alert behaviour earlier than did groups exposed to pulsating treatments or no lamp. Interestingly, light …

Identification Of 24 Polymorphic Microsatellite Markers For The Double-Crested Cormorant (Phalacrocorax Auritus), Jennifer A. Fike, Travis L. Devault, Olin E. Rhodes Jr.

United States Department of Agriculture Wildlife Services: Staff Publications

Twenty-four polymorphic microsatellite markers were developed for the double-crested cormorant (Phalacrocorax auritus). The number of alleles ranged from two to 13 and observed heterozygosities ranged from 0.032 to 0.871. The use of these loci should enable researchers and biologists to learn more about the population structure and ecology of this species.

Observations On The Use Of Gonacon™ In Captive Female Elk (Cervus Elaphus), Gary Killian, Terry J. Kreeger, Jack Rhyan, Kathleen Fagerstone, Lowell Miller

United States Department of Agriculture Wildlife Services: Staff Publications

Overabundant populations of elk (Cervus elaphus) are a significant concern in some areas of the western United States because of potential ecologic damage and spread of brucellosis to domestic livestock. Brucella abortus is transmitted among elk through direct contact with aborted fetuses, placentas and associated fluids, or postpartum discharge of infected animals. Because transmission of brucellosis is dependent on pregnancy, contraception of cows could be used for both disease and population management. The objective of this study was to evaluate the contraceptive efficacy of a gonadotropin-releasing hormone vaccine (GonaCon^TM) in female elk. In September 2004, cows …

Selective Foraging For Anthropogenic Resources By Black Bears: Minivans In Yosemite National Park, Stewart W. Breck, Nathan Lance, Victoria Seher

United States Department of Agriculture Wildlife Services: Staff Publications

Black bears (Ursus americanus) forage selectively in natural environments. To determine if bears also forage selectively for anthropogenic resources we analyzed data on vehicles broken into by bears from Yosemite National Park, California. We classified vehicles into 9 categories based on their make and model and collected data on use (2001–2007) and availability (2004–2005). From 2001 to 2007 bears broke into 908 vehicles at the following rates: minivan (26.0%), sport–utility vehicle (22.5%), small car (17.1%), sedan (13.7%), truck (11.9%), van (4.2%), sports car (1.7%), coupe (1.7%), and station wagon (1.4%). Only use of minivans (29%) during 2004–2005 was …

Wildlife Collisions With Aircraft: A Missing Component Of Land-Use Planning For Airports, Bradley F. Blackwell, Travis L. Devault, Esteban Fernández-Juricic, Richard A. Dolbeer

United States Department of Agriculture Wildlife Services: Staff Publications

Projecting risks posed to aviation safety by wildlife populations is often overlooked in airport land-use planning. However, the growing dependency on civil aviation for global commerce can require increases in capacity at airports which affect land use, wildlife populations, and perspectives on aviation safety. Our objectives were to (1) review legislation that affects airports and surrounding communities relative to managing and reducing wildlife hazards to aviation; (2) identify information gaps and future research needs relative to regulated land uses on and near airports, and the effects on wildlife populations; and (3) demonstrate how information regarding wildlife responses to land-use practices …

No Adverse Effects Of Simultaneous Vaccination With The Immunocontraceptive GonaconTm And A Commercial Rabies Vaccine On Rabies Virus Neutralizing Antibody Production In Dogs, Scott C. Bender, David L. Bergman, Krista M. Wenning, Lowell A. Miller, Charles E. Rupprecht, Dennis Slate, Felix R. Jackson

United States Department of Agriculture Wildlife Services: Staff Publications

Parenteral vaccination campaigns are integral to the elimination of canine rabies. To maximize herd immunity in dogs, immunocontraception provided at the time of rabies vaccination should reduce fecundity and dog abundance. GonaCon^TM has been used successfully as an immunocontraceptive in a variety of mammals, and by inference, the dog would be an ideal candidate for testing. As an initial step in evaluating a combination-vaccination program, we assessed the effects of GonaCon^TM on rabies virus neutralizing antibody production in dogs after administration of a veterinary rabies vaccine. Eighteen feral/free ranging dogs were included in this initial study: six were …

A Tool Box Half Full: How Social Science Can Help Solve Human–Wildlife Conflict, Sharon Baruch-Mordo, Kenneth R. Wilson, John Broderick, Stewart W. Breck

United States Department of Agriculture Wildlife Services: Staff Publications

There is a growing recognition among wildlife managers that focusing management on wildlife often provides a temporary fix to human–wildlife conflicts, whereas changing human behavior can provide long-term solutions. Human dimensions research of wildlife conflicts frequently focuses on stakeholders’ characteristics, problem identification, and acceptability of management, and less frequently on human behavior and evaluation of management actions to change that behavior. Consequently, little information exists to assess overall success of management. We draw on our experience studying human–bear conflicts, and argue for more human dimensions studies that focus on change in human behavior to measure management success. We call for …

Effects Of A Synthetic Gonadotrophin-Releasing Hormone Agonist, Leuprolide, On Rut-Associated Events In Male Red Deer, G. K. Barrell, S. C. T. Schaafsma, M. J. Ridgway, M. Wellby, L. A. Miller

United States Department of Agriculture Wildlife Services: Staff Publications

This study examined the effectiveness of leuprolide, a gonadotrophin-releasing hormone agonist, in suppressing rut-associated events in farmed male red deer. In mid-January (~6 weeks before the rut period in the southern hemisphere) adult red deer (Cervus elaphus scoticus) stags that had been allocated to three groups (n = 10 per group) received leuprolide, administered subcutaneously in a 90-day release formulation, at zero (control), low (22.5 mg) or high (45 mg) doses. Following treatment with leuprolide there was evidence of suppression of mean plasma luteinising hormone concentration that was significant (P < 0.05) at 9 weeks. Mean plasma testosterone concentration of all three groups rose following treatment, then declined prematurely in the low- and high-dose leuprolide-treated groups, so that it was significantly (P < 0.05) suppressed (0.66 ± 0.29 and 2.0 ± 0.88 ng mL^–1, low and high dose respectively) in …
