Only One Went Through The Green Door, Rachel Sahaidachny

Graduate Thesis Collection

Written in three parts, Only One Went through the Green Door, explores abandonment, homelessness, childhood, womanhood, and choices made or unmade that create the complicated and winding path of life. The poems use narrative and lyric to examine the effects of childhood trauma on the development of a persona, and its shadow. Emotional realities explored through natural landscapes, and at times through child-like language, create an unsettled speaker who quests for some final understanding that might lead to peace.

Blockade Of Fibroblast Activation Protein In Combination With Radiation Treatment In Murine Models Of Pancreatic Adenocarcinoma., Andrew J Gunderson, Tomoko Yamazaki, Kayla Mccarty, Michaela Phillips, Alejandro F Alice, Shelly Bambina, Lauren Zebertavage, David Friedman, Benjamin Cottam, Pippa Newell, Michael J. Gough, Marka R Crittenden, Pieter Van Der Veken, Kristina H Young

Articles, Abstracts, and Reports

Pancreatic ductal adenocarcinoma (PDAC) is characterized by a fibrotic stroma with a poor lymphocyte infiltrate, in part driven by cancer-associated fibroblasts (CAFs). CAFs, which express fibroblast activation protein (FAP), contribute to immune escape via exclusion of anti-tumor CD8+ T cells from cancer cells, upregulation of immune checkpoint ligand expression, immunosuppressive cytokine production, and polarization of tumor infiltrating inflammatory cells. FAP is a post-proline peptidase selectively expressed during tissue remodeling and repair, such as with wound healing, and in the tumor microenvironment by cancer-associated fibroblasts. We targeted FAP function using a novel small molecule inhibitor, UAMC-1110, and mice with germline knockout …

Lymphatic Migration Of Immune Cells., Henry R Hampton, Tatyana Chtanova

Articles, Abstracts, and Reports

Lymphatic vessels collect interstitial fluid that has extravasated from blood vessels and return it to the circulatory system. Another important function of the lymphatic network is to facilitate immune cell migration and antigen transport from the periphery to draining lymph nodes. This migration plays a crucial role in immune surveillance, initiation of immune responses and tolerance. Here we discuss the significance and mechanisms of lymphatic migration of innate and adaptive immune cells in homeostasis, inflammation and cancer.

The Procreation Prescription: Sexuality, Power, And The Veil Of Morality, Lauren Dimartino

City University of New York Law Review

While considering the dark history that links the regulation of women’s sexuality to governmental efforts to restrain women’s political, social, and economic power, this note argues that the Federal Administration under the 45th President of the United States is unconstitutionally relying on the veil of morality to regulate sexuality and reproductive rights. To provide context on how sexual regulation is a tool of women’s oppression, the note offers a brief background on the importance of contraception to women’s equality and, thus, a women’s potential for power. It then lays the groundwork for how power is defined and maintained—particularly through the …

Culture And The Development Of Traditional Medicine In Africa, Rowland Edet, Oyedolapo Isaac Bello, Julianah Babajide

Department of Sociology: Faculty Publications

Traditional medicine has been the dominant healthcare system in Africa before westernization, civilization and colonialism. For people living in the rural areas, traditional medicine is easily available, accessible and affordable. The purpose of this paper is to examine how the cultural way of the life of Africans has contributed to the emergence and development of traditional therapeutic systems in the continent. By explaining the way Africans perceive illness and disease, this paper argues that various forms of healing were predicated on the sociocultural environment of the people. The paper therefore opts for concerted efforts in the development of traditional medicine …

Depressive symptoms and cognitive functioning were both measured in 2012 and 2015. Scores across cognitive …

When Viruses Infect Plants, Hernan Garcia-Ruiz

Department of Plant Pathology: Faculty Publications

Just as human beings can catch a cold, plants can also get viral infections. Understanding the mechanisms regulating the interactions between plants and viruses is the first step towards developing better management strategies and using biotechnology methods to immunise plants and engineer genetic resistance to viruses in plants. This is the focus of research by Dr Hernan Garcia-Ruiz and his team based at the University of Nebraska, USA.

Viral diseases in plants can cause important economic losses as a result of poor-quality products and lower yield. This impact can particularly seriously affect developing countries which are more likely to be …

Public Policy Limitations On Trademark Subject Matter: A U.S. Perspective, Christine Farley

Contributions to Books

This chapter provides an overview of the public policy limitations on trademark subject matter under U.S. law. This is an area of law that had been fairly stable until recently. The U.S. Supreme Court’s 2017 decision striking down the prohibition on registering disparaging marks and its 2019 decision striking down the prohibition on registering immoral and scandalous marks may prompt a larger reexamination of the policy justifications for denying trademark registration.

Allowable Take Of Black Vultures In The Eastern United States, Guthrie Zimmerman, Brian A. Millsap, Michael L. Avery, John R. Sauer, Michael C. Runge, Kenneth D. Richkus

United States Department of Agriculture Wildlife Services: Staff Publications

Black vultures (Coragyps atratus) have been increasing in density and expanding their range in the eastern United States since at least the 1960s. In many areas, their densities have increased to the level where they are causing damage to property and livestock and the number of requests for allowable take permits has increased throughout these areas. The United States Fish and Wildlife Service (USFWS) requires updated information to help inform the number of take permits that could reduce conflicts while meeting obligations under the Migratory Bird Treaty Act.We expanded analyses used to estimate allowable take in Virginia to …

Effects Of Repeated Sublethal External Exposure To Deep Water Horizon Oil On The Avian Metabolome, Brian S. Dorr, Katie C. Hanson-Dorr, Fariba M. Assadi-Porter, Ebru Selin Selen, Katherine A. Healy, Katherine E. Horak

United States Department of Agriculture Wildlife Services: Staff Publications

We assessed adverse effects of external sublethal exposure of Deepwater Horizon, Mississippi Canyon 252 oil on plasma and liver metabolome profiles of the double-crested cormorant (Phalacrocorax auritus), a large (1.5 to 3.0 kg) diving waterbird common in the Gulf of Mexico. Metabolomics analysis of avian plasma showed significant negative effects on avian metabolic profiles, in some cases after only two external exposures (26 g cumulative) to oil. We observed significant (p < 0.05) changes in intermediate metabolites of energy metabolism and fatty acid and amino acid metabolic pathways in cormorants after repeated exposure to oil. Exposure to oil increased several metabolites (glycine, betaine, serine and methionine) that are essential to the one-carbon metabolism pathway. Lipid metabolism was affected, causing an increase in production of ketone bodies, suggesting lipids were used as an alternative energy source for energy production in oil exposed birds. In addition, metabolites associated with hepatic bile acid metabolism were affected by oil exposure which was correlated with changes observed in bile acids in exposed birds. These changes at the most basic level of phenotypic expression caused by sublethal exposure to oil can have effects that would be detrimental to reproduction, migration, and survival in avian species.

Group Effects Of A Non-Native Plant Invasion On Rodent Abundance, Bryan M. Kluever, Trinity N. Smith, Eric M. Gese

United States Department of Agriculture Wildlife Services: Staff Publications

Cheatgrass (Bromus tectorum) is the most prolific invading plant in western North America. Investigations determining the impact of this invasion on population state variables and community dynamics of rodents have largely occurred at the community or species level, creating a knowledge gap as to whether rodents affiliated by a shared taxonomy or other grouping are differentially affected by cheatgrass invasion. We examined rodent abundance along a gradient of cheatgrass cover using various groupings of two nocturnal rodent taxa comprising the majority of the rodent community in the Great Basin Desert. In the summers of 2010–2013, rodents were sampled …

The Intrepid Urban Coyote: A Comparison Of Bold And Exploratory Behavior In Coyotes From Urban And Rural Environments, Stewart W. Breck, Sharon A. Poessel, Peter Mahoney, Julie K. Young

United States Department of Agriculture Wildlife Services: Staff Publications

Coyotes (Canis latrans) are highly adaptable, medium-sized carnivores that now inhabit nearly every large city in the United States and Canada. To help understand how coyotes have adapted to living in urban environments, we compared two ecologically and evolutionarily important behavioral traits (i.e., bold-shy and exploration-avoidance behavior) in two contrasting environments (i.e., rural and urban).

Boldness is an individual’s reaction to a risky situation and exploration is an individual’s willingness to explore novel situations. Our results from both tests indicate that urban coyotes are bolder and more exploratory than rural coyotes and that within both populations there are …

Machine Learning To Classify Animal Species In Camera Trap Images: Applications In Ecology, Michael A. Tabak, Mohammad S. Norouzzadeh, David W. Wolfson, Steven J. Sweeney, Kurt C. Vercauteren, Nathan P. Snow, Joseph M. Halseth, Paul A. Di Salvo, Jesse S. Lewis, Michael D. White, Ben Teton, James C. Beasley, Peter E. Schlichting, Raoul K. Boughton, Bethany Wight, Eric S. Newkirk, Jacob S. Ivan, Eric A. Odell, Ryan K. Brook, Paul M. Lukacs, Anna K. Moeller, Elizabeth G. Mandeville, Jeff Clune, Ryan S. Miller

United States Department of Agriculture Wildlife Services: Staff Publications

1. Motion-activated cameras (“camera traps”) are increasingly used in ecological and management studies for remotely observing wildlife and are amongst the most powerful tools for wildlife research. However, studies involving camera traps result in millions of images that need to be analysed, typically by visually observing each image, in order to extract data that can be used in ecological analyses.

2. We trained machine learning models using convolutional neural networks with the ResNet-18 architecture and 3,367,383 images to automatically classify wildlife species from camera trap images obtained from five states across the United States. We tested our model on an …

Cause‐Specific Mortality Of The World’S Terrestrial Vertebrates, Jacob E. Hill, Travis L. Devault, Jerrold L. Belant

United States Department of Agriculture Wildlife Services: Staff Publications

Aim: Vertebrates are declining worldwide, yet a comprehensive examination of the sources of mortality is lacking. We conducted a global synthesis of terrestrial vertebrate cause‐specific mortality to compare the sources of mortality across taxa and determine predictors of susceptibility to these sources of mortality.

Location: Worldwide.

Time period: 1970–2018.

Major taxa studied: Mammals, birds, reptiles and amphibians.

Methods: We searched for studies that used telemetry to determine the cause of death of terrestrial vertebrates. We determined whether each mortality was caused by anthropogenic or natural sources and further classified mortalities within these two categories (e.g. harvest, vehicle collision and predation). …

Feral Swine Harming Insular Sea Turtle Reproduction: The Origin, Impacts, Behavior And Elimination Of An Invasive Species, Richard M. Engeman, Robert W. Byrd, Jamie Dozier, Mark A. Mcalister, James O. Edens, Elizabeth M. Kierepka, Timothy J. Smyser, Noel Myers

United States Department of Agriculture Wildlife Services: Staff Publications

Feral swine are among the world's most destructive invasive species wherever they are found, with translocations figuring prominently in their range expansions. In contrast, sea turtles are beloved species that are listed as threatened or endangered throughout the world and are the focus of intense conservation efforts. Nest predation by feral swine severely harms sea turtle reproduction in many locations around the world. Here we quantify and economically assess feral swine nest predation at North Island, South Carolina, an important loggerhead sea turtle nesting beach. Feral swine depredation of North Island sea turtle nests was first detected in 2005, with …

A Bioeconomic Model For The Optimization Of Local Canine Rabies Control, Aaron Anderson, Johann Kotze, Stephanie A. Shwiff, Brody Hatch, Chris Slootmaker, Anne Conan, Darryn Knobel, Louis H. Nel

United States Department of Agriculture Wildlife Services: Staff Publications

We present a new modeling tool that can be used to maximize the impact of canine rabies management resources that are available at the local level. The model is accessible through a web-based interface that allows for flexibility in the management strategies that can be investigated. Rabies vaccination, sterilization, chemo-contraception, and euthanasia can be specified and limited to specific demographic groups. Additionally, we allowed for considerable complexity in the specification of management costs. In many areas, the costs of contacting additional dogs increases as management effort increases, and this can have important strategic implications. We illustrated the application of the …

No Detection Of Brodifacoum Residues In The Marine And Terrestrial Food Web Three Years After Rat Eradication At Palmyra Atoll, Central Pacific, A. Wegmann, G. Howald, S. Kropidlowski, N. Holmes, A.B. Shiels

United States Department of Agriculture Wildlife Services: Staff Publications

Invasive alien species represent one of the greatest threats to native plants and animals on islands. Rats (Rattus spp.) have invaded most of the world’s oceanic islands, causing lasting or irreversible damage to ecosystems and biodiversity. To counter this threat, techniques to eradicate invasive rats from islands have been developed and applied across the globe. Eradication of alien rats from large or complex island ecosystems has only been successful with the use of bait containing a rodenticide. While effective at eradicating rats from islands, rodenticide can persist in the ecosystem longer than the time required to eradicate the target rat …

Ecological Functions Of Vertebrate Scavenging, James C. Beasley, Zachary H. Olson, Nuria Selva, Travis L. Devault

United States Department of Agriculture Wildlife Services: Staff Publications

Introduction

The role of vertebrate scavenging in food web dynamics has historically been minimalized and portrayed as the activity of a select group of obligate scavengers (e.g., vultures), with a simplistic linkage between carrion and detritivores in food webs. Research in the last few decades, however, has revealed that the role of carrion in food web dynamics is severely underestimated, highly complex, and pervasive among ecosystems across the globe (DeVault et al. 2003; Selva and Fortuna 2007; Wilson and Wolkovich 2011). Such observations have led to a surge in research interest in scavenging ecology that continues to reveal new information …

Department of Biochemistry: Faculty Publications

To breed improved biomass cultivars of Miscanthus ×giganteus, it will be necessary to select the highest‐yielding and best‐adapted genotypes of its parental species, Miscanthus sinensis and Miscanthus sacchariflorus. We phenotyped a diverse clonally propagated panel of 569 M. sinensis and nine natural diploid M. ×giganteus at one subtropical (Zhuji, China) and five temperate locations (Sapporo, Japan; Leamington, Ontario, Canada; Fort Collins, CO; Urbana, IL; and Chuncheon, Korea) for dry biomass yield and 14 yield‐component traits, in trials grown for 3 years. Notably, dry biomass yield of four Miscanthus accessions exceeded 80 Mg/ha in Zhuji, China, approaching …

Factors Associated With Pesticide Resistance In Culex Mosquitoes, Jude Akpan

Walden Dissertations and Doctoral Studies

In recent years mosquito-borne diseases have reemerged, largely because of pesticide resistance. The mosquitoes develop resistance to pesticides because of broad and repeated uses of pesticides. Preventing the development of pesticide resistance requires proper understanding of the environmental factors potentially associated with the development of the resistance. The purpose of this study was to investigate the environmental factors associated with the resistance to pesticides by the Culex mosquitoes. This correlational study included the analysis of archived data samples (N = 29,794) from the Field Cage Tests results conducted between 2013 and 2017 by a large county public health department. The …

Perceptions Of Economic, Health, And Environmental Effects Of Hydraulic Fracturing In Indiana, Juliana Bayowa

Walden Dissertations and Doctoral Studies

Effects of hydraulic fracturing (HF) have become a controversial public health issue in the United States. The purpose of this qualitative case study was to explore community members' perceptions of economic, health, and environmental effects of HF in Gibson County, Indiana. The conceptual framework was adapted from the health belief model and was named the HF health impact belief model (HFHIBM). Data were collected from stratified purposeful non-randomly selected 32 Gibson community members, using semi structured questionnaires, complete observations, and existing documents. Stratification was based on factors influencing perception, such as, gender, race, level of education, age or technology exposure, …

The purpose of this multiple case study was to explore the strategies some food and beverage industry leaders in the United States used for implementing sustainable water consumption practices to improve operational efficiency. The conceptual framework for the study was stakeholder theory. The primary data source was semistructured interviews with 4 food and beverage industry leaders in Wisconsin who have responsibility for implementing their firms' sustainability practices, and the secondary data source was corporate sustainability reports. …

The Impact Of Childhood Trauma And Personality On Kinkiness In Adulthood, Kaitlyn Hillier

Walden Dissertations and Doctoral Studies

Historically, kinky sexualities and sexual behaviors have been understood as pathological or perverse. Such misunderstandings and misrepresentations have contributed to the development and perpetuation of kink stigma. The aim of this retrospective, cross-sectional, correlational research study was to explore the potential relationship(s) between pathology, personality, and kinky sexual behaviors/roles in adulthood. Guided by queer-feminist theory, the research questions addressed whether personality traits, experiences of childhood trauma, or a combination thereof, were predictors for kinky behaviors/roles in adulthood. A multi measure, anonymous, and confidential survey was distributed online including the Childhood Traumatic Events Scale as a childhood trauma questionnaire, the Mini-IPIP, …

Ehdv-2 Infection Prevalence Varies In Culicoides Sonorensis After Feeding On Infected White-Tailed Deer Over The Course Of Viremia, Sandra Y. Mendiola, Mary K. Mills, Elin Maki, Barbara S. Drolet, William C. Wilson, Roy D. Berghaus, David E. Stallknecht, Jonathan Breitenbach, D. Scott Mcvey, Mark G. Ruder

School of Veterinary and Biomedical Sciences: Faculty Publications

Epizootic hemorrhagic disease viruses (EHDVs) are arboviral pathogens of white-tailed deer and other wild and domestic ruminants in North America. Transmitted by various species of Culicoides, EHDVs circulate wherever competent vectors and susceptible ruminant host populations co-exist. The impact of variation in the level and duration of EHDV viremia in white-tailed deer (Odocoileus virginianus) on Culicoides infection prevalence is not well characterized. Here we examined how infection prevalence in a confirmed North American vector of EHDV-2 (Culicoides sonorensis) varies in response to fluctuations in deer viremia. To accomplish this, five white-tailed deer were experimentally infected with EHDV-2 and colonized C. …

Turning Privacy Inside Out, Julie E. Cohen

Georgetown Law Faculty Publications and Other Works

The problem of theorizing privacy moves on two levels, the first consisting of an inadequate conceptual vocabulary and the second consisting of an inadequate institutional grammar. Privacy rights are supposed to protect individual subjects, and so conventional ways of understanding privacy are subject-centered, but subject-centered approaches to theorizing privacy also wrestle with deeply embedded contradictions. And privacy’s most enduring institutional failure modes flow from its insistence on placing the individual and individualized control at the center. Strategies for rescuing privacy from irrelevance involve inverting both established ways of talking about privacy rights and established conventions for designing institutions to protect …

Reflecting On Straight Talk On Trade, Alvaro Santos

Georgetown Law Faculty Publications and Other Works

A question that motivates this essay is: What insights can we offer from legal scholarship that Dani Rodrik could take on board and put to good use?

Rodrik is an economist, but he might as well have been a lawyer in the way he builds his argument and anticipates counterarguments. I mean that as a compliment. As a bonus, he delivers the punch line with humor and grace. In his book I recognized several of the many contributions Rodrik has made: his argument for policy space and revitalization of industrial policy, the globalization trilemma, the idea and process of growth …

Nuclear Envelope Organization In Dictyostelium Discoideum, Petros Batsios, Ralph Gräf, Michael P. Koonce, Denis A. Larochelle, Irene Meyer

Biology

The nuclear envelope consists of the outer and the inner nuclear membrane, the nuclear lamina and the nuclear pore complexes, which regulate nuclear import and export. The major constituent of the nuclear lamina of Dictyostelium is the lamin NE81. It can form filaments like B-type lamins and it interacts with Sun1, as well as with the LEM/HeH-family protein Src1. Sun1 and Src1 are nuclear envelope transmembrane proteins involved in the centrosome-nucleus connection and nuclear envelope stability at the nucleolar regions, respectively. In conjunction with a KASH-domain protein, Sun1 usually forms a so-called LINC complex. Two proteins with functions reminiscent of …
