Toxicity Reference Values For Chlorophacinone And Their Application For Assessing Anticoagulant Rodenticide Risk To Raptors, Barnett A. Rattner, Katherine E. Horak, Rebecca S. Lazarus, Sandra L. Schultz, Susan Knowles, Benjamin G. Abbo, Steven F. Volker

United States Geological Survey: Staff Publications

Despite widespread use and benefit, there are

growing concerns regarding hazards of second-generation

anticoagulant rodenticides to non-target wildlife which

may result in expanded use of first-generation compounds,

including chlorophacinone (CPN). The toxicity of CPN

over a 7-day exposure period was investigated in American

kestrels (Falco sparverius) fed either rat tissue mechanically-

amended with CPN, tissue from rats fed Rozol bait

(biologically-incorporated CPN), or control diets (tissue

from untreated rats or commercial bird of prey diet)

ad libitum. Nominal CPN concentrations in the formulated

diets were 0.15, 0.75 and 1.5 µg/g food wet weight, and

measured concentrations averaged 94 …

Decadal Re-Evaluation Of Contaminant Exposure And Productivity Of Ospreys (Pandion Haliaetus) Nesting In Chesapeake Bay Regions Of Concern, Rebecca S. Lazarus, Barnett A. Rattner, Peter C. Mcgowan, Robert C. Hale, Sandra L. Schultz, Natalie K. Karouna-Renier, Mary Ann Ottinger

United States Geological Survey: Staff Publications

The last large-scale ecotoxicological study of ospreys (Pandion haliaetus) in Chesapeake Bay was conducted in 2000-2001 and focused on U.S. EPA-designated Regions of Concern (ROCs; Baltimore Harbor/ Patapsco, Anacostia/middle Potomac, and Elizabeth Rivers). In 2011-2012, ROCs were re-evaluated to determine spatial and temporal trends in productivity and contaminants. Concentrations of p,p'-DDE were low in eggs and below the threshold associated with eggshell thinning. Eggs from the Anacostia/ middle Potomac Rivers had lower total PCB concentrations in 2011 than in 2000; however, concentrations remained unchanged in Baltimore Harbor. Polybrominated diphenyl ether flame retardants declined by 40%, and five alternative …

A Simple Web-Based Tool To Compare Freshwater Fish Data Collected Using Afs Standard Methods, Scott A. Bonar, Norman Mercado-Silva, Matt Rahr, Yuta T. Torrey, Averill Cate Jr.

United States Geological Survey: Staff Publications

The American Fisheries Society (AFS) recently published Standard Methods for Sampling North American Freshwater Fishes. Enlisting the expertise of 284 scientists from 107 organizations throughout Canada, Mexico, and the United States, this text was developed to facilitate comparisons of fish data across regions or time. Here we describe a user-friendly web tool that automates among-sample comparisons in individual fish condition, population length-frequency distributions, and catch per unit effort (CPUE) data collected using AFS standard methods. Currently, the web tool (1) provides instantaneous summaries of almost 4,000 data sets of condition, length frequency, and CPUE of common freshwater fishes collected …

Exposure Of Feral Swine (Sus Scrofa) In The United States To Selected Pathogens, John A. Baroch, Carl A. Gagnon, Sonia Lacouture, Marcelo Gottschalk

United States Department of Agriculture Wildlife Services: Staff Publications

Feral swine (Sus scrofa) are widely distributed in the United States. In 2011 and 2012, serum samples and tonsils were recovered from 162 and 37 feral swine, respectively, in the US to evaluate exposure to important swine endemic pathogens. Antibodies against porcine reproductive and respiratory syndrome virus (PRRSV) and porcine circovirus type 2 (PCV2) were found in 2.5% and 25.3% of tested sera, respectively. Positive serological reactions against Mycoplasma hyopneumoniae and Actinobacillus pleuropneumoniae have been detected in 19.7% and 69.7% of animals. More than 15% of animals presented antibodies against these 2 pathogens simultaneously. Most animals were also …

Bmp7 Drives Human Adipogenic Stem Cells Into Metabolically Active Beige Adipocytes, Meshail Okla, Jung-Heun Ha, Ryan E. Temel, Soonkyu Chung

Department of Nutrition and Health Sciences: Faculty Publications

Adult humans have a substantial amount of inducible-brown (or beige) fat, which is associated with increased energy expenditure and reduced weight gain via thermogenesis. Despite the identification of key regulators of beige adipogenesis, impacts of dietary factors on adaptive thermogenesis are largely unknown, partly due to a lack of validated human cell models. Bone morphogenetic protein 7 (BMP7) is known to promote brown adipogenesis in rodent and human progenitor cells. However, controversy still surrounds the cellular identity in BMP7-mediated transition of white to brown adipocytes. The aim of this study is to confirm BMP7-derived human adipocytes as a relevant in …

Evaluating Behavioral Syndromes In Coyotes (Canis Latrans), Julie K. Young, Marion Mahe, Stewart W. Breck

United States Department of Agriculture Wildlife Services: Staff Publications

As more research focuses on behavioral syndromes and their role in ecological and evolutionary processes, it is imperative that methods to test behavior are valid. The objectives of this study were to (1) assess behavior in captive coyotes (Canis latrans) using three methods [agitation scores, novel object test, and flightinitiation distance (FID)] and (2) to determine whether the three tests were correlated within individuals to describe behavioral syndromes. Female coyotes had higher agitation scores during handling (2.6 ± 0.5) than males (1.5 ± 0.3; t = 1.90, p = 0.06): scores ranged from 0 to 8 on a …

Underreporting Of Wildlife-Vehicle Collisions Does Not Hinder Predictive Models For Large Ungulates, Nathan P. Snow, William F. Porter, David M. Williams

United States Department of Agriculture Wildlife Services: Staff Publications

Conflicts from wildlife–vehicle collisions (WVCs) pose serious challenges for managing and conserving large ungulates throughout the world. However, underreporting of large proportions of WVCs (i.e., two-thirds of WVCs in some cases) creates concern for relying on governmental databases to inform management strategies of WVCs. Our objective was to test the sensitivity of WVC studies to underreporting using 2 species of large ungulates that experience substantial incidences of collisions but exist in different environmental settings: white-tailed deer (Odocoileus virginianus) in agricultural-dominated central Illinois and moose (Alces alces) in forest-dominated western Maine, USA. We estimated baseline relationships between …

Characterization Of The Inflammatory Phenotype Of Mycobacterium Avium Subspecies Paratuberculosis Using A Novel Cell Culture Passage Model, Jamie L. Everman, Torsten M. Eckstein, Jonathan Roussey, Paul M. Coussens, John Bannantine, Luiz E. Bermudez

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Understanding the pathogenic mechanisms of Mycobacterium avium subspecies paratuberculosis (MAP) and the host responses to Johne’s disease is complicated by the multi-faceted disease progression, late-onset host reaction and the lack of available ex vivo infection models. We describe a novel cell culture passage model that mimics the course of infection in vivo. The developed model simulates the interaction of MAP with the intestinal epithelial cells, followed by infection of macrophages and return to the intestinal epithelium. MAP internalization triggers a minimal inflammatory response. After passage through a macrophage phase, bacterial reinfection of MDBK epithelial cells, representing the late phase of …

Isoproterenol Increases Uncoupling, Glycolysis, And Markers Of Beiging In Mature 3t3-L1 Adipocytes., Colette N Miller, Jeong-Yeh Yang, Emily England, Amelia Yin, Clifton A Baile, Srujana Rayalam

PCOM Scholarly Works

Beta-adrenergic activation stimulates uncoupling protein 1 (UCP1), enhancing metabolic rate. In vitro, most work has studied brown adipocytes, however, few have investigated more established adipocyte lines such as the murine 3T3-L1 line. To assess the effect of beta-adrenergic activation, mature 3T3-L1s were treated for 6 or 48 hours with or without isoproterenol (10 and 100 μM) following standard differentiation supplemented with thyroid hormone (T3; 1 nM). The highest dose of isoproterenol increased lipid content following 48 hours of treatment. This concentration enhanced UCP1 mRNA and protein expression. The increase in UCP1 following 48 hours of isoproterenol increased oxygen consumption rate. …

Faithful Translations?: Cross-Cultural Communication In Canadian Religious Freedom Litigation, Howard Kislowicz

Osgoode Hall Law Journal

In three religious freedom cases pursued to the Supreme Court of Canada—Amselem, Multani, and Huterrian Brethren of Wilson Colony—religious freedom claimants engaged in litigation over a religious practice particular to their group. Some have argued that cases like these can be seen as cross-cultural encounters. How did the religious freedom claimants seek to make their practices—the succah, the kirpan, and the prohibition on being photographed—understood to the courts? And how did the courts respond to these claims? In this article, I draw out two central values from the literature on crosscultural communication: respect and self-awareness. I then use these values …

Shareholder Litigation Without Class Actions, David H. Webber

Faculty Scholarship

In this Article, I imagine a post-class action landscape for shareholder litigation. Assuming, for the sake of this exercise, an environment in which both securities-fraud and transactional class actions are hobbled by procedural or substantive reforms — most likely through the adoption of mandatory-arbitration provisions or fee-shifting provisions — I assess what shareholder litigation would disappear, what would remain, and what a post-class action landscape would look like. I argue that loss of the class action would remove a layer of legal insulation that prevents institutional investors from having to pursue positive value claims against companies. Currently, the class action …

Fidelity To Our Living Constitution, James E. Fleming

Faculty Scholarship

This essay explores the arguments of Bruce Ackerman, who decries the Roberts Court’s “shattering judicial betrayal” of our living constitution’s Civil Rights Revolution. He argues for a broader conception of the constitutional canon: The higher law of the Constitution includes not only formally adopted provisions but also “landmark statutes” and judicial “superprecedents,” for example, those of the Civil Rights Revolution. He also argues for a broader conception of popular sovereignty: We the People manifest our will not only through the formal amending procedures but also through higher lawmaking procedures outside Article V. He exhorts us to fidelity to our living …

Puzzles Of Proportion And The Reasonable Military Commander: Reflections On The Law, Ethics, And Geopolitics Of Proportionality, Robert D. Sloane

Faculty Scholarship

This article offers modest reflections on jus in bello proportionality. It suggests that the law of armed conflict (LOAC) build on the only consensus legal standard that exists: that of the good-faith reasonable military commander. The difficulty — here, as with any reasonableness standard — is to identify factors that realistically can, and legally should, guide adherence to it and to consider the objective and subjective dimensions of judgments under the standard. Part II scrutinizes the content and status of Additional Protocol I’s (API) canonical definition of proportionality. It analyzes its text and context to bring out the extent to …

Escaping Cascadia, Todd Albertson

University Honors Theses

The preface, "Dualism and Narrative Mode," details the development of realist techniques and then looks to current research to address the question, "In what other ways can realism be maximized within fiction?" It proposes a style combining second-person imperative narration for the viewpoint character’s actions and third-person free indirect discourse for description and internalization.

The introduction, "The Geography of the Future," explores prediction within select literary works, explains mitigation reactions to such predictions, and details current geographical projections to build a picture of what the future will look like and how humans will interact with their environment.

Escaping Cascadia is …

Evaluating The Success Of Forest Restoration, Josh Adams

University Honors Theses

Forest restoration projects are occurring throughout the world. Restoration projects can vary greatly depending on the type of forest and the type of stressors that have caused ecosystem degradation and the need for restoration. Because of this variability, and because objective criteria for determining the success of restoration projects are lacking, it is difficult to evaluate the overall success of forest restoration projects. Using ecological standards developed for river restoration as a model, a similar set of standards was applied to forest restoration projects. The standards put forward can be used to evaluate the success of ecosystem restoration universally through …

Digitally Enhanced Classrooms: Understanding The Effect Of Individualized Technology On Language Arts Instruction In Elementary Schools, Celine De Clercq

University Honors Theses

The use of technology in elementary classroom settings has been increasing every year. Many schools already included computer classes; however, recently there has been a large move towards individualized, or 1:1, technology as well. We now find certain schools have acquired tablets and laptops for each student – fully integrating modern technology with traditional instruction. However, in the effort to keep up with the surge of technology, schools may be ignoring the need for professional development and curriculum planning to support technology as a tool that enhances student learning. While working in an “Apple Distinguished” school that provided individual tablets …

Green Roofs Support A Wide Diversity Of Collembola In Urban Portland, Oregon, Konrad Miziolek

University Honors Theses

Green roofs can help address habitat loss in urban areas by supporting plant and animal communities. To determine whether green roofs can support collembola biodiversity, we collected pitfall samples from April-June 2015 on two extensive and two intensive green roofs in urban Portland, Oregon. Twenty morphospecies were found across the roofs, indicating that green roofs support a diversity of collembola taxa. The intensive roofs were more biodiverse than the extensive, though roof type may not be the most significant factor affecting collembolan biodiversity. Each of the four green roofs were characterized by a different and unique most dominant morphospecies, and, …

Geochemistry And Petrography Of Igneous Components Of The Dalles Formation In The Dufur West Quadrangle, Oregon, Heather H. Herinckx

University Honors Theses

The Dalles Formation is a sequence of volcanic, volcaniclastic and sedimentary deposits of the late Miocene to Pliocene. The unit stretches along the eastern flanks of Mount Hood from Maupin, northward to the Columbia River, near The Dalles, Oregon (Figure 1). The Dalles Formation consists of lavas that are generally dacitic in composition and are composed of block-and-ash flows, debris-flows, and reworked fluvial sediments. Past workers have mapped the unit as the Dalles Formation "Undivided". The scope of this project has been to investigate the geochemical and petrographic characteristics and whether they may suggest distinct units. A section of the …

Using Computer-Aided Design Software And 3d Printers To Improve Spatial Visualization, Petros Katsioloudis, Millie Jones

STEMPS Faculty Publications

Many articles have been published on the use of 3D printing technology. From prefabricated homes and outdoor structures to human organs, 3D printing technology has found a niche in many fields, but especially education. The education of technology and engineering students has come a long way from traditional instruction using hand drawings. Although drawings may still be a part of a students learning, computer technology has been embraced in this field for several years. With the introduction of AutoCAD technical drawing programs and now 3D printing, learners can use 3D printed models to develop their spatial abilities in technology and …

Unfair And Deceptive Robots, Woodrow Hartzog

Faculty Scholarship

Robots, like household helpers, personal digital assistants, automated cars, and personal drones are or will soon be available to consumers. These robots raise common consumer protection issues, such as fraud, privacy, data security, and risks to health, physical safety and finances. Robots also raise new consumer protection issues, or at least call into question how existing consumer protection regimes might be applied to such emerging technologies. Yet it is unclear which legal regimes should govern these robots and what consumer protection rules for robots should look like.

The thesis of the Article is that the FTC’s grant of authority and …

Media: Mean Distance Association And Its Applications In Nonlinear Gene Set Analysis., Hesen Peng, Junjie Ma, Yun Bai, Jianwei Lu, Tianwei Yu

PCOM Scholarly Works

Probabilistic association discovery aims at identifying the association between random vectors, regardless of number of variables involved or linear/nonlinear functional forms. Recently, applications in high-dimensional data have generated rising interest in probabilistic association discovery. We developed a framework based on functions on the observation graph, named MeDiA (Mean Distance Association). We generalize its property to a group of functions on the observation graph. The group of functions encapsulates major existing methods in association discovery, e.g. mutual information and Brownian Covariance, and can be expanded to more complicated forms. We conducted numerical comparison of the statistical power of related methods under …

A Coxiella-Like Endosymbiont Is A Potential Vitamin Source For The Lone Star Tick, Todd A. Smith, Timothy Driscoll, Joseph J. Gillespie, Rahul Raghavan

Biology Faculty Publications and Presentations

Amblyomma americanum (Lone star tick) is an important disease vector in the United States. It transmits several human pathogens, including the agents of human monocytic ehrlichiosis, tularemia, and southern tick-associated rash illness. Blood-feeding insects (Class Insecta) depend on bacterial endosymbionts to provide vitamins and cofactors that are scarce in blood. It is unclear how this deficiency is compensated in ticks (Class Arachnida) that feed exclusively on mammalian blood. A bacterium related to Coxiella burnetii, the agent of human Q fever, has been observed previously within cells of A. americanum. Eliminating this bacterium (CLEAA, Coxiella-like endosymbiont of A. americanum) with antibiotics …

An Exploration Of The Wheel-Induced Feeding-Suppression, Stephen Benjamin Peckham

Theses and Dissertations (Comprehensive)

Anorexia nervosa is an enigmatic human condition typified by food-restriction that is often accompanied by extensive exercise. This has been modeled in rats in the wheel-induced feeding-suppression (WIFS) model. In this model, animals are given access to a running-wheel, which induces a volitional drop in food-consumption. Short periods of wheel access have induced a feeding-suppression which is effectively reversed by chlorpromazine administration (Adams et al., 2009). Recent attempts at replicating Adams et al.’s (2009) feeding-suppression have, however, been unsuccessful (Peckham et al., 2013). These attempts raised questions as to whether or not the existing methodology is most effective at suppressing …

Characterization Of The Trans-Plasma Membrane Electron Transport System In The Myelin Membrane, Afshan Sohail

Theses and Dissertations (Comprehensive)

Myelination is the key feature of evolution in the nervous system of vertebrates. Myelin is the protrusion of glial cells. More specifically, "oligodendrocytes" in the central nervous system (CNS), and "Schwann" cells in the peripheral nervous system (PNS) form myelin membranes. Myelin remarkably, enhances the propagation of nerve impulses. However, myelin restricts the access of extracellular metabolites to the axons. A pathology called "demyelination" is associated with myelin. The myelin sheath is not only an insulator, but it is itself metabolically active. In this study it is hypothesized that the ratio of NAD(P)⁺/NAD(P)H and the glycolytic pathway of …

The Spirit Of Haudenosaunee Youth: The Transformation Of Identity And Well-Being Through Culture-Based Activism, Bonnie M. Freeman

Theses and Dissertations (Comprehensive)

This dissertation examines the connection between Indigenous knowledge and culture-based action, and how this connection facilitates a sense of identity and well-being for Haudenosaunee youth. This study examines the experience of fourteen Haudenosaunee youth and five parents/adults as they ran for four summers (2005-2008) on a youth-led spiritual journey known as the Unity Run. On this journey youth travelled throughout Haudenosaunee traditional territory (Ontario and Quebec, Canada; and New York State, U.S.A.) and beyond (Virginia, North Carolina, Tennessee) carrying a message of peace, unity and social justice.

The methodology of this research is framed within Haudenosaunee traditional protocols (visiting and …
