New Evidence Suggests Southern China As A Common Source Of Multiple Clusters Of Highly Pathogenic H5n1 Avian Influenza Virus, Bin Wu, Chengmin Wang, Guoying Dong, Yunhai Guo, Dale L. Nolte, Thomas Jude Deliberto, Jianguo Xu, Mingxing Duan, Hongxuan He

United States Department of Agriculture Wildlife Services: Staff Publications

Highly pathogenic H5N1 avian influenza is considered an avian disease, although there is some evidence of limited human-to-human transmission of the virus. A global effort is underway to control or eradicate the highly pathogenic H5N1 avian influenza virus in poultry and prevent human exposure, both of which may also reduce the risk of pandemic emergence. Hemagglutinin gene sequences from 215 human H5N1 influenza viruses were used to trace the source and dispersal pattern of human H5N1 influenza viruses on a global scale. A mutation network and phylogenetic analyses of the hemagglutinin gene show that human H5N1 influenza viruses can be …

Identification And Management Of Wildlife Damage, Kurt C. Vercauteren, Richard A. Dolbeer, Eric M. Gese

United States Department of Agriculture Wildlife Services: Staff Publications

Wildlife management is often thought of in terms of protecting, enhancing, and nurturing wildlife populations and the habitat needed for their well-being. However, many species at one time or another require management actions to reduce conflicts with people, other wildlife species, or other resources. Examples include an airport manager modifying habitats to reduce gull (family Laridae) activity near runways, a forester poisoning pocket gophers (family Geomyidae) to increase tree seedling survival in a reforestation project, or a biologist trapping an abundant predator or competing species to enhance survival of an endangered species. These are just a few of many examples …

Dramatic And Immediate Improvements In Insular Nesting Success For Threatened Sea Turtles And Shorebirds Following Predator Management, Richard M. Engeman, Anthony Duffiney, Sally Braem, Christina Olsen, Bernice Constantin, Parks Small, John Dunlap, J.C. Griffin

United States Department of Agriculture Wildlife Services: Staff Publications

Predation critically threatens reproductive success of sea turtles and shorebirds at many of Florida's beaches. We examined the biological and bioeconomic results of predator management on two adjacent barrier islands, Cayo Costa and North Captiva, along Florida's west coast. Both islands suffered severe nesting losses due to predation and disturbance due to raccoons, while Cayo Costa also was impacted by a large population of feral swine. In 2006, our initial year of study, neither island received predator management and no least tern production occurred on either island, and sea turtle nest predation was 74% and 60%, respectively, for Cayo Costa …

Raccoon (Procyon Lotor) Movements And Dispersal Associated With Ridges And Valleys Of Pennsylvania: Implications For Rabies Management, Robert B. Puskas, Justin W. Fischer, Craig B. Swope, Mike R. Dunbar, Robert G. Mclean, J. Jeffrey Root

United States Department of Agriculture Wildlife Services: Staff Publications

The raccoon (Procyon lotor) continues to be a prominent terrestrial rabies reservoir in the eastern United States. Describing the dispersal and movements of these animals and determining geographic features that are natural hindrances or corridors to movements could be used to assist oral rabies vaccination efforts. The landscape of the ridge-and-valley system in Pennsylvania exhibits characteristics of both natural potential hindrances and travel corridors to the movements of wildlife. The movements of 49 raccoons were monitored throughout a ridge and two adjacent valley sites to assess their movements related to these landscape features. Results suggest that few raccoons …

Superabundant Food At Catfish Aquaculture Facilities Improves Body Condition In American White Pelicans, D. Tommy King, Jerold Belant, Brent Harrel, James Glahn

United States Department of Agriculture Wildlife Services: Staff Publications

Few studies have investigated the use of aquaculture-produced foods by piscivorous birds. American White Pelicans (Pelecanus erythrorhynchos) were collected from four locations (two aquaculture, one riverine and one coastal) in the southeastern United States during winter and spring 1998-1999 to assess the contribution (biomass, frequency of occurrence) of aquaculture-produced foods and their effect on body condition. Pelican diets reflected opportunistic foraging across locations. Diet near catfish ponds consisted mostly of Channel Catfish (Ictalurus punctatus). Diets along the Mississippi River had similarly high biomass of catfish, but otolith counts suggested lower use of catfish. Diets near crawfish ( …

Arthropods Of A Semi-Natural Grassland In An Urban Environment: The John F. Kennedy International Airport, New York, Lisa Kutschbach-Brohl, Brian E. Washburn, Glen E. Bernhardt, Richard B. Chipman, Laura C. Francoeur

United States Department of Agriculture Wildlife Services: Staff Publications

Semi-natural grassland habitat fragments, such as those found on airports, might be important for arthropod conservation and biodiversity in urban ecosystems. The objectives of this study were to: (1) describe the arthropod communities present within the grasslands on the John F. Kennedy International Airport and (2) assess spatial and temporal variation in those arthropod communities. We collected arthropods using a vacuum sampler during 2003 and using sweep-net collection methods during 2003 and 2004. During 2003, a total of 1,467 arthropods, representing 17 orders and 68 families were found in vacuum samples. A total of 3,784 arthropods, representing 12 orders and …

Do The Effects Of Corruption Upon Growth Differ Across Political Regimes?, Andreas Assiotis, Kevin Sylwester

Economics Discussion Papers

Many studies find that corruption lowers economic growth. However, most of these studies do not consider whether the effects of corruption upon growth differ across countries. This paper investigates whether the association between corruption and economic growth differs between democracies and authoritarian regimes. Consider illegal corruption and legal lobbying, both forms of rent seeking, as imperfect substitutes. Suppose lobbying is easier to do in democracies. Then, lowering corruption in authoritarian regimes could have greater growth benefits because of the lower substitutability between corruption and lobbying in these countries. Using cross-country, annual data from 1984 to 2007, we regress economic growth …

Associative / Dissociative Cognitive Strategies In Sustained Physical Activity: Literature Review And Proposal For A Mindfulness-Based Conceptual Model, Paul Salmon, Scott Hanneman, Brandon Harwood

Faculty and Staff Scholarship

We reviewed and summarize the extant literature on associative/dissociative cognitive strategies used by athletes and others in circumstances necessitating periods of sustained attention. This review covers studies published since a prior publication by Masters and Ogles (1998), and, in keeping with their approach, offers a methodological critique of the literature. We conclude that the distinction between associative and dissociative strategies has outlived its usefulness since initially proposed in an earlier era of ground-breaking research by Morgan and Pollock (1977) that was influenced to some extent by psychodynamic thinking. In recent years there has been an evolutionary shift in concepts of …

General Flips And The Cd-Index, Daniel J. Wells

University of Kentucky Doctoral Dissertations

We generalize bistellar operations (often called flips) on simplicial manifolds to a notion of general flips on PL-spheres. We provide methods for computing the cd-index of these general flips, which is the change in the cd-index of any sphere to which the flip is applied. We provide formulas and relations among flips in certain classes, paying special attention to the classic case of bistellar flips. We also consider questions of "flip-connecticity", that is, we show that any two polytopes in certain classes can be connected via a sequence of flips in an appropriate class.

The Role Of Racial Information In Infant Face Processing, Angela Nicole Hayden

University of Kentucky Doctoral Dissertations

The present research addressed the development of specialization in face processing in infancy by examining the roles of race and emotion. An other-race face among own-race faces draws adults’ attention to a greater degree than an own-race face among other-race faces due to the “other-race” feature in other-race faces. This feature underlies race-based differences in adults’ face processing. The current studies investigated the development of this mechanism as well as the influence that this mechanism has on emotion processing in infancy.

In Experiment 1, Caucasian 3.5- and 9- month-olds exhibited a preference for a pattern containing an Asian face among …

Nanoscale Functionalization And Characterization Of Surfaces With Hydrogel Patterns And Biomolecules, Hariharasudhan Chirra Dinakar

University of Kentucky Doctoral Dissertations

The advent of numerous tools, ease of techniques, and concepts related to nanotechnology, in combination with functionalization via simple chemistry has made gold important for various biomedical applications. In this dissertation, the development and characterization of planar gold surfaces with responsive hydrogel patterns for rapid point of care sensing and the functionalization of gold nanoparticles for drug delivery are highlighted.

Biomedical micro- and nanoscale devices that are spatially functionalized with intelligent hydrogels are typically fabricated using conventional UV-lithography. Herein, precise 3-D hydrogel patterns made up of temperature responsive crosslinked poly(N-isopropylacrylamide) over gold were synthesized. The XY control of the hydrogel …

Single View Reconstruction For Human Face And Motion With Priors, Xianwang Wang

University of Kentucky Doctoral Dissertations

Single view reconstruction is fundamentally an under-constrained problem. We aim to develop new approaches to model human face and motion with model priors that restrict the space of possible solutions. First, we develop a novel approach to recover the 3D shape from a single view image under challenging conditions, such as large variations in illumination and pose. The problem is addressed by employing the techniques of non-linear manifold embedding and alignment. Specifically, the local image models for each patch of facial images and the local surface models for each patch of 3D shape are learned using a non-linear dimensionality reduction …

Late Pleistocene-Early Holocene Colonization And Regionalization In Northern Perú: Fishtail And Paiján Complexes Of The Lower Jequetepeque Valley, Greg J. Maggard

University of Kentucky Doctoral Dissertations

Until relatively recently, the view of Late Pleistocene hunter-gatherers in the Americas was dominated by the “Clovis-first” paradigm. However, recent discoveries have challenged traditional views and forced reconsiderations of the timing, processes, and scales used in modeling the settlement of the Americas. Chief among these discoveries has been the recognition of a wide range of early cultural diversity throughout the Americas that is inconsistent with previously held notions of cultural homogeneity.

During the Late Pleistocene-Early Holocene, the development of widely varying economic, technological and mobility strategies in distinct environments is suggestive of a range of different adaptations and traditions.

It …

LP Bounded Point Evaluations For Polynomials And Uniform Rational Approximation, Erin Militzer

University of Kentucky Doctoral Dissertations

A connection is established between uniform rational approximation, and approximation in the mean by polynomials on compact nowhere dense subsets of the complex plane C. Peak points for R(X) and bounded point evaluations for H^p(X, dA), 1 ≤ p < ∞, play a fundamental role.

Development Of Novel Ahr Antagonists, Hyosung Lee

University of Kentucky Doctoral Dissertations

Aryl hydrocarbon receptor (AHR) is a sensor protein, activated by aromatic chemical species for transcriptionally regulating xenobiotic metabolizing enzymes. AHR is also known to be involved in a variety of pathogenesis such as cancer, diabetes mellitus, cirrhosis, asthma, etc. The AHR signaling induced by xenobiotics has been intensively studied whereas its physiological role in the absence of xenobiotics is poorly understood. Despite a number of ligands of AHR have been reported thus far, further applications are still hampered by the lack of specificity and/or the partially agonistic activity. Thus, a pure AHR antagonist is needed for deciphering the AHR cryptic …

The Rhetoric Of Destruction: Racial Identity And Noncombatant Immunity In The Civil War Era, James M. Bartek

University of Kentucky Doctoral Dissertations

This study explores how Americans chose to conduct war in the mid-nineteenth century and the relationship between race and the onset of “total war” policies. It is my argument that enlisted soldiers in the Civil War era selectively waged total war using race and cultural standards as determining factors. A comparative analysis of the treatment of noncombatants throughout the United States between 1861 and 1865 demonstrates that nonwhites invariably suffered greater depredations at the hands of military forces than did whites. Five types of encounters are examined: 1) the treatment of white noncombatants by regular Union and Confederate forces; 2) …

Innocent Threats, Concealed Consent And The Necessary Presence Of Strict Liability In Traditional Fault-Based Tort Law, Marin Roger Scordato

Scholarly Articles

This article identifies and carefully analyzes the use in tort law of what is termed unilateral and bilateral legal analysis. Unilateral, or one-party, analysis involves the design of legal doctrine that is focused on the characteristics or status of a single legal person. It is traditionally associated with criminal law, where the doctrinal attention is tightly focused on the criminal defendant. Inquiry may be made regarding the nature and degree of harm suffered by the victim, or whether the victim agreed to the harm producing act, but these considerations are generally relevant only to the degree that they shed light …

Freedom Not To Listen: A Constitutional Analysis Of Compulsory Indoctrination Through Workplace Captive Audience Meetings, Roger C. Hartley

Scholarly Articles

Workplace captive audience meetings are assemblies of employees during paid work time in which employers compel employees to listen to antiunion and other types of proselytizing. Employers enforce attendance at workplace captive audience meetings by threats of discharge. Typically, employers deny employees the right to ask questions or express disagreement with the anti-union views presented during these mandatory meetings. Soon after the enactment of the National Labor Relations Act (NLRA), the National Labor Relations Board (NLRB) concluded that workplace captive audience meetings discussing unionization are per se unlawful. However, the NLRB reversed course following the enactment of the 1947 Taft-Hartley …

Archaeological Evidence For Resilience Of Pacific Northwest Salmon Populations And The Socioecological System Over The Last ~7,500 Years, Sarah K. Campbell, Virginia L. Butler

Anthropology Faculty Publications and Presentations

Archaeological data on the long history of interaction between indigenous people and salmon have rarely been applied to conservation management. When joined with ethnohistoric records, archaeology provides an alternative conceptual view of the potential for sustainable harvests and can suggest possible social mechanisms for managing human behavior. Review of the ~7,500-year-long fish bone record from two subregions of the Pacific Northwest shows remarkable stability in salmon use. As major changes in the ecological and social system occurred over this lengthy period, persistence in the fishery is not due simply to a lack of perturbation, but rather indicates resilience in the …

Cold Weather And The Potential Range Of Invasive Burmese Pythons, Michael L. Avery, Richard M. Engeman, Kandy L. Keacher, John S. Humphrey, William E. Bruce, Tom C. Mathies, Richard E. Mauldin

United States Department of Agriculture Wildlife Services: Staff Publications

The Burmese python (Python molurus bivittatus) is established in Everglades National Park and neighboring areas in south Florida. Beyond its substantial ecological impacts to native fauna in south Florida, concerns have been raised as to its potential to occupy other parts of the USA, even as far north as Washington, DC. During a recent period of cold weather, seven of nine captive Burmese pythons held in outdoor pens at our facility in north-central Florida died, or would have died absent our intervention. This cold-induced mortality occurred despite the presence of refugia with heat sources. Our findings cast doubt …

Comparison Of Endocrine Response To Stress Between Captive-Raised And Wild-Caught Bighorn Sheep, Sarah Coburn, Mo Salman, Jack Rhyan, Thomas Keefe, Matthew Mccollum, Keith Aune, Terry Spraker, Lowell Miller

United States Department of Agriculture Wildlife Services: Staff Publications

Stress hormones in Rocky Mountain bighorn sheep (Ovis canadensis canadensis), produced in response to environmental changes, road development, or high population density, may impact their immune systems to a threshold level that predisposes them to periodic, large-scale mortality. We compared the stress response to a novel environmental situation and repeated handling between bighorn sheep born and raised in captivity (CR) and bighorn sheep born in the wild (WC) and brought into captivity. We measured plasma epinephrine, norepinephrine, cortisol, and fecal glucocorticoid metabolites (FGM). Three weeks after each group’s arrival we used a one-time drop-net event to elicit an …

Kill Rates And Predation Patterns Of Jaguars (Panthera Onca) In The Southern Pantanal, Brazil, Sandra M. C. Cavalcanti, Eric M. Gese

United States Department of Agriculture Wildlife Services: Staff Publications

Jaguars (Panthera onca) often prey on livestock, resulting in conflicts with humans. To date, kill rates and predation patterns by jaguars have not been well documented. We studied the foraging ecology of jaguars in an area with both livestock and native prey and documented kill rates, characteristics of prey killed, patterns of predation, and the influence of prey size on the duration at kill sites and the time interval between kills. Between October 2001 and April 2004 we monitored 10 jaguars equipped with global positioning system (GPS) collars. We collected 11,787 GPS locations and identified 1,105 clusters of …

Feral Swine Behavior Relative To Aerial Gunning In Southern Texas, Tyler A. Campbell, David Long, Bruce Leland

United States Department of Agriculture Wildlife Services: Staff Publications

Feral swine (Sus scrofa) impact resources through their destructive feeding behavior, competition with native wildlife, and impacts to domestic animal agriculture. We studied aerial gunning on feral swine to determine if aerial gunning altered home range and core area sizes, distances between home range centroids, and distances moved by surviving individuals. We collected data before, during, and after aerial gunning in southern Texas. Using Global Positioning System collars deployed on 25 adult feral swine at 2 study sites, we found home range and core area sizes did not differ before and after aerial gunning. However, feral swine moved …

The Effect Of Enclosure Type On The Behavior And Heart Rate Of Captive Coyotes, Stacey P. Brummer, Eric M. Gese, John A. Shivik

United States Department of Agriculture Wildlife Services: Staff Publications

The potential for captivity to elicit changes in animal behavior and physiology is well known. Recent research on captive populations has examined the effect of feeding protocols, enclosure types, and enrichment programs on indices of stress and displays of species-typical behaviors. We investigated the impact of enclosure type upon captive coyotes (Canis latrans) by examining differences in coyote behavior and heart rate, among 3.3m² kennels (K), 65.5m² small pens (S), and 1000m² large pens (L). Time budgets and repertoire of species-specific behaviors were compared among each enclosure type and to a sample of wild (W) …
