Beyond The Narrow Harvard Model Of Legal Education: Restoring Legal Education According To The Proposals Of Valentin Tomberg, Brian Mccall

Faculty Articles

Professor Mark Jones has argued that legal education needs to be “reliberalized” by returning to a state in which “all law students receive a basic minimum exposure to the general subject areas of legal history, jurisprudence, and comparative law, as well as to the general subject areas of international/trans-national/global legal studies . . . .” Jones’s call to restore the cultural dimensions has recently received an additional source of strength. The recent publication of an English translation of Dr. Valentin Tomberg’s doctoral dissertation for the first time, under the title The Art of the Good: The Regeneration of Fallen Jurisprudence, …

How El Salvador Has Changed U.S. Law By A Bit: The Consequences For The Ucc Of Bitcoin Becoming Legal Tender, Brian Mccall

Faculty Articles

On June 8, 2021, the Congress of El Salvador passed a law that changed American commercial law.How could a foreign country change U.S. law? El Salvador’s Congress voted to confer “legal tender” status upon the cryptocurrency Bitcoin.The law took effect in El Salvador on September 7, 2021;starting that day, Bitcoin could be used to pay taxes4 and buy goods and services in El Salvador. As the first country to adopt Bitcoin as legal tender, El Salvador made world history and sparked many debates and predictions about the effects its decision may have on the Central American nation and its economy.Beyond …

The Fourth Amendment In The Age Of Autonomous Vehicles, Tracy Hresko Pearl

Faculty Articles

Autonomous vehicles exist at the intersection of two extremely turbulent areas of Fourth Amendment jurisprudence—traffic stops and emerging technologies—and have implications for virtually every major search and seizure doctrine developed over the last century. Complicating matters even further is the fact that car manufacturers are developing these vehicles at varying rates, meaning that vehicles with differing levels of automation are being introduced onto the consumer market at different (and often unpredictable) times. Each level of vehicle automation, in turn, poses unique issues for law enforcement. Semi-autonomous (Levels 2 and 3) vehicles make it extremely difficult for police to distinguish between …

Health Risk Perceptions Regarding Electronic Nicotine Delivery Systems (Ends) Among Individuals With Respiratory Illnes, Sarah Ann Sebban

Theses and Dissertations

Electronic nicotine delivery systems (ENDS), also known as electronic cigarettes, are portable battery-powered devices used to smoke or “vape” a flavored solution which usually contains nicotine. Many national organizations (CDC, AMA, AAFP, ALA, AHA) have recognized the alarmingly increased rates of ENDS use in the United States, especially among certain populations. Those most likely to engage in ENDS use are youth and young adults, and adults who already smoke combustible cigarettes. Many people perceive ENDS use as a healthier alternative to smoking regular cigarettes and thus, are more willing to initiate ENDS use. However, research has indicated that ENDS use …

Hey! That's How I Feel! A Qualitative Content Analysis Of Anxiety In Middle Grade Literature, Heather M. Wood

Graduate Research Papers

The purpose of this qualitative content analysis is to examine quality literature focused on anxiety as a mental health concern for middle grade readers and to identify which books should be promoted widely for students and recommended to teachers to support an SEL approach to the curriculum. The analysis of 10 middle grade books (Appendix A) using a book analysis tool (Appendix B) based on previous research completed by Wickham (2018) and Monaghan (2016) and as consistent with CASEL 5 identified four definitive themes in all 10 books. The four themes discovered were:

The Perspectives Of Augmentative And Alternative Communication Experts On The Clinical Integration Of Non-Invasive Brain-Computer Interfaces, Kevin Pitt, Miechelle L. Mckelvey, Kristy Weissling

Department of Special Education and Communication Disorders: Faculty Publications

As brain-computer interface for augmentative and alternative communication access (BCI-AAC) development continues to consider avenues for translation into the clinical setting, the perspectives of clinician experts in AAC should be considered. Therefore, 11 USA-based speech-language pathologists who are experts in AAC completed a semistructured interview along with Likert scale measures to assess their perspectives on BCI-AAC. The interviews and scales explored the potential impact of BCI-AAC, along with barriers and solutions to BCI-AAC implementation. Speech-language pathologists estimated that 1.5% to 50% of their caseload may benefit from BCI-AAC across various settings. Further, identified barriers and solutions included (a) BCI-AAC implementation …

Dynamic Causal Modeling Of Neural Responses To An Orofacial Pneumotactile Velocity Array, Yingying Wang, Rebecca Custead, Hyuntaek Oh, Steven M. Barlow

Department of Special Education and Communication Disorders: Faculty Publications

The effective connectivity of neuronal networks during orofacial pneumotactile stimulation with different velocities is still unknown. The present study aims to characterize the effectivity connectivity elicited by three different saltatory velocities (5, 25, and 65 cm/s) over the lower face using dynamic causal modeling on functional magnetic resonance imaging data of twenty neurotypical adults. Our results revealed the contralateral SI and SII as the most likely sources of the driving inputs within the sensorimotor network for the pneumotactile stimuli, suggesting parallel processing of the orofacial pneumotactile stimuli. The 25 cm/s pneumotactile stimuli modulated forward interhemispheric connection from the contralateral SII …

Ankrd24 Organizes Triobp To Reinforce Stereocilia Insertion Points, Jocelyn F. Krey, Chang Liu, Inna A. Belyantseva, Michael Bateschell, Rachel A. Dumont, Jennifer Goldsmith, Paroma Chatterjee, Rachel S. Morrill, Lev M. Fedorov, Sarah Foster, Jinkyung Kim, Alfred L. Nuttal, Sherri M. Jones, Dongseok Choi, Thomas B. Friedman, Anthony J. Ricci, Bo Zhao, Peter G. Barr-Gillespie

Department of Special Education and Communication Disorders: Faculty Publications

The stereocilia rootlet is a key structure in vertebrate hair cells, anchoring stereocilia firmly into the cell’s cuticular plate and protecting them from overstimulation. Using superresolution microscopy, we show that the ankyrin-repeat protein ANKRD24 concentrates at the stereocilia insertion point, forming a ring at the junction between the lower and upper rootlets. Annular ANKRD24 continues into the lower rootlet, where it surrounds and binds TRIOBP-5, which itself bundles rootlet F-actin. TRIOBP-5 is mislocalized in Ankrd24^KO/KO hair cells, and ANKRD24 no longer localizes with rootlets in mice lacking TRIOBP-5; exogenous DsRed–TRIOBP-5 restores endogenous ANKRD24 to rootlets in these mice. Ankrd24 …

Reinventing Opportunities For Argentina: Vista Oil And Gas, Emiliano Cabrera

Dartmouth College Master’s Theses

In the last century, Argentina faced an astonishing economic downturn that remains until today, frustrating all who learn its economic history, explore the country's potential, and stay in tune with its political-economic present. This research examines Argentina's economic history, revises the main drivers that signed its economic drama, and proposes guidelines to address new opportunities by encouraging its private sector. By using Vista Oil and Gas as an exemplary case, this work proposes Vista's business model as an initiative perfectly compatible with the primary macroeconomic needs that Argentina currently has that should be highly considered for developing its private sector. …

Plague Risk In The Western United States Over Seven Decades Of Environmental Change, Colin J. Carlson, Sarah N. Bevins, Boris V. Schmid

United States Department of Agriculture Wildlife Services: Staff Publications

After several pandemics over the last two millennia, the wildlife reservoirs of plague (Yersinia pestis) now persist around the world, including in the western United States. Routine surveillance in this region has generated comprehensive records of human cases and animal seroprevalence, creating a unique opportunity to test how plague reservoirs are responding to environmental change. Here, we test whether animal and human data suggest that plague reservoirs and spillover risk have shifted since 1950. To do so, we develop a new method for detecting the impact of climate change on infectious disease distributions, capable of disentangling long-term trends (signal) and …

A Systematic Map Of Human-Carnivore Coexistence, Cassandre C. Venumière-Lefebvre, Stewart W. Breck, Kevin R. Crooks

United States Department of Agriculture Wildlife Services: Staff Publications

Carnivore populations globally have largely declined, and coexistence, where humans and carnivores share landscapes, plays a crucial role in carnivore conservation. However, the term “coexistence” is often used in scientific and popular literature without being clearly defined. Herein, we provide a global perspective on what coexistence is and how it is studied. We conducted a systematic map of 366 articles published between 1987 and 2020 to characterize human-carnivore coexistence literature according to coexistence definitions, temporal trends, geographic and taxonomic focus, and four thematic aspects of coexistence: carnivore ecology, human endeavors, social conflict and human-carnivore conflict. We used chi-squared tests and …

Wild Pig Removal Reduces Pathogenic Bacteria In Low-Order Streams, Sara A. Bolds, B. Graeme Lockaby, Latif Kalin, Stephen S. Ditchkoff, Mark D. Smith, Kurt Vercauteren

United States Department of Agriculture Wildlife Services: Staff Publications

Invasive wild pig populations have undergone enormous increases in the United States and particularly across the southern U.S. in recent years. High fecundity rates and abilities to adapt quickly to varied habitats have enabled pig populations to become entrenched and difficult to eliminate. The pigs cause many negative impacts on ecosystems including degradation of water quality through infusion of fecal contamination and other non-point source pollutants. Our goal was to determine the effects of pig removal on water quality in streams that were known to be significantly polluted by pig activity Bolds (J Environ Qual 50: 441–453, 2021). We compared …

Relationship Between Reproductive Hormones And Migration Distance In A Polygynous Songbird, The Red‑Winged Blackbird (Agelaius Phoeniceus), Michelle A. Eshleman, Page E. Klug, Esther Morales‑Vega, Björn Wissel, Timothy J. Grelves

United States Department of Agriculture Wildlife Services: Staff Publications

Many bird species migrate to southern overwintering locations to avoid harsh conditions at their breeding grounds, but at the cost of an energetically demanding migration that may delay their spring reproductive development. Previous work on the relationship between migration distance and reproductive readiness has primarily focused on early season baseline testosterone in both males and females. However, for females, testosterone alone may not be the appropriate measurement of reproductive development. Estradiol, a metabolite of testosterone that is essential for breeding behaviors and reproduction, should also be measured. Furthermore, baseline testosterone varies throughout the day and may change due to social …

A Model For Leveraging Animal Movement To Understand Spatio-Temporal Disease Dynamics, Mark Q. Wilber, Anni Yang, Raoul Boughton, Kezia R. Manlove, Ryan S. Miller, Kim M. Pepin, George Wittemyer

United States Department of Agriculture Wildlife Services: Staff Publications

The ongoing explosion of fine-resolution movement data in animal systems provides a unique opportunity to empirically quantify spatial, temporal and individual variation in transmission risk and improve our ability to forecast disease outbreaks. However, we lack a generalizable model that can leverage movement data to quantify transmission risk and how it affects pathogen invasion and persistence on heterogeneous landscapes. We developed a flexible model ‘Movement-driven modelling of spatio-temporal infection risk’ (MoveSTIR) that leverages diverse data on animal movement to derive metrics of direct and indirect contact by decomposing transmission into constituent processes of contact formation and duration and pathogen deposition …

Accounting For Animal Movement Improves Vaccination Strategies Against Wildlife Disease In Heterogeneous Landscapes, Katherine M. Mcclure, Guillaume Bastille-Rousseau, Amy J. Davis, Carolyn A. Stengel, Kathleen M. Nelson, Richard B. Chipman, George Wittemyer, Zaid Abdo, Amy Gilbert, Kim M. Pepin

United States Department of Agriculture Wildlife Services: Staff Publications

Oral baiting is used to deliver vaccines to wildlife to prevent, control, and eliminate infectious diseases. A central challenge is how to spatially distribute baits to maximize encounters by target animal populations, particularly in urban and suburban areas where wildlife such as raccoons (Procyon lotor) are abundant and baits are delivered along roads. Methods from movement ecology that quantify movement and habitat selection could help to optimize baiting strategies by more effectively targeting wildlife populations across space. We developed a spatially explicit, individual-based model of raccoon movement and oral rabies vaccine seroconversion to examine whether and when baiting …

Concentration-Response Of An Anthraquinone-Based Repellent For Raccoons (Procyon Lotor), Shylo Johnson, Shelagh T. Deliberto, Kathleen Urchek, Amy T. Gilbert, Scott J. Werner

United States Department of Agriculture Wildlife Services: Staff Publications

Wildlife repellents can be part of non-lethal management strategies to reduce the negative impacts of wildlife to property, agricultural production, and human health and safety. Raccoons (Procyon lotor) are associated with negative impacts in all three of these areas. Anthraquinone is a useful avian repellent and its utility as a mammalian repellent is still being explored. Our objective was to evaluate laboratory efficacy of an anthraquinone-based repellent for raccoons using different concentrations. We fed captive raccoons whole corn treated at 0.5%, 1%, 1.5% and 2% anthraquinone and examined their behavioral response related to feeding repellency including consumption and change in …

Using Noninvasive Genetics For Estimating Density And Assessing Diet Of Urban And Rural Coyotes In Florida, Usa, Bryan M. Kluever, Martin B. Main, Stewart W. Breck, Robert C. Lonsinger, John H. Humphrey, Justin W. Fischer, Michael P. Milleson Usda Aphis Wildlife Services, Gainesville, Antionette J. Piaggio

United States Department of Agriculture Wildlife Services: Staff Publications

Coyotes (Canis latrans) are expanding their range and due to conflicts with the public and concerns of Coyotes affecting natural resources such as game or sensitive species, there is interest and often a demand to monitor Coyote populations. A challenge to monitoring is that traditional invasive methods involving live-capture of individual animals are costly and can be controversial. Natural resource management agencies can benefit from contemporary noninvasive genetic sampling approaches aimed at determining key aspects of Coyote ecology (e.g., population density and food habits). However, the efficacy of such approaches under different environmental conditions is poorly understood. Our …

Spatial Risk Modeling Of Cattle Depredation By Black Vultures In The Midwestern United States, Brandon M. Quinby, Bryan M. Kluever, Grant N. Burcham, Lee Humberg, Landon R. Jones, Marian L. Wahl, Patrick A. Zollner

United States Department of Agriculture Wildlife Services: Staff Publications

ock operations through depredation of stock are a cause of human‐wildlife conflict. Management of such conflict requires identifying environmental and non‐environmental factors specific to a wildlife species' biology and ecology that influence the potential for livestock depredation to occur. Identification of such factors can improve understanding of the conditions placing livestock at risk. Black vultures (Coragyps atratus) have expanded their historical range northward into the midwestern United States. Concomitantly, an increase in concern among agricultural producers regarding potential black vulture attacks on livestock has occurred. We estimated area with greater or lesser potential for depredation of domestic cattle by black …

Invasive Predators Affect Community-Wide Pollinator Visitation, Christina T. Liang, Aaron B. Shiels, William P. Haines, Manette E. Sandor, Clare E. Aslan

United States Department of Agriculture Wildlife Services: Staff Publications

Disruption of plant–pollinator interactions by invasive predators is poorly understood but may pose a critical threat for native ecosystems. In a multiyear field experiment in Hawai’i, we suppressed abundances of globally invasive predators and then observed insect visitation to flowers of six native plant species. Three plant species are federally endangered (Haplostachys haplostachya, Silene lanceolata, Tetramolopium arenarium) and three are common throughout their range (Bidens menziesii, Dubautia linearis, Sida fallax). Insect visitors were primarily generalist pollinators, including taxa that occur worldwide such as solitary bees (e.g., Lasioglossum impavidum), social bees (e.g., …

Rodents In Agriculture: A Broad Perspective, Gary Witmer

United States Department of Agriculture Wildlife Services: Staff Publications

The largest taxonomic group of mammals is rodents, with over 2200 species known around the world [1]. More recently, it was stated that over 2500 species exist [2]. Many species exist on all continents, with the exception of Antarctica. Rodents have adapted to all ecosystems of the world, including tundra, alpine, temperate forests, grasslands, arid regions, and aquatic systems. They provide many ecosystem functions, including soil aeration and mixing, seed and spore dispersal, vegetation succession, and being an important food source for predatory animals. Some species of rodents are even consumed by people in some parts of the world. Most …

Transmission Of Antibiotic Resistance At The Wildlife-Livestock Interface, Shinyoung Lee, Peixin Fan, Ting Liu, Anni Yang, Raoul K. Boughton, Kim M. Pepin, Ryan S. Miller, Kwangcheol Casey Jeong

United States Department of Agriculture Wildlife Services: Staff Publications

Antibiotic-resistant microorganisms (ARMs) are widespread in natural environments, animals (wildlife and livestock), and humans, which has reduced our capacity to control life threatening infectious disease. Yet, little is known about their transmission pathways, especially at the wildlife-livestock interface. This study investigated the potential transmission of ARMs and antibiotic resistance genes (ARGs) between cattle and wildlife by comparing gut microbiota and ARG profiles of feral swine (Sus scrofa), coyotes (Canis latrans), cattle (Bos taurus), and environmental microbiota. Unexpectedly, wild animals harbored more abundant ARMs and ARGs compared to grazing cattle. Gut microbiota of cattle was …

Economic Damages Of Wild Pigs In Non-Traditional Areas: From The Fairway To The After Life, Sophie Mckee, Julie Elser, Maryfrances Miller, Lirong Liu, Ryan Miller, Steven S. Shwiff, Stephanie A. Shwiff

United States Department of Agriculture Wildlife Services: Staff Publications

Invasive wild pigs are widely known to cause damage to agricultural properties and commodities, but less has been reported about damages to other types of property. A survey was distributed to golf courses and cemeteries across Texas to explore the extent of damage these properties experience. While both property types reported significant damages, golf courses were found to experience more damage than cemeteries. Using average reported costs and predicted county-level damage, total costs for all golf courses and cemeteries across the state were estimated to exceed $1.6 million USD per year.

Strength In Numbers: Avian Influenza A Virus Transmission To Poultry From A Flocking Passerine, J. Jeffrey Root, Jeremy W. Ellis, Susan A. Shriner

United States Department of Agriculture Wildlife Services: Staff Publications

The effects of flock size of European starlings (Sturnus vulgaris) was experimentally manipulated to assess the potential of influenza A virus (IAV; H4N6) transmission from a flocking passerine to bobwhite quail (Colinus virginianus) through shared food and water resources to mimic starling intrusions into free-range and backyard poultry operations. Of the three starling flock sizes tested (n = 30, n = 20 and n = 10), all successfully transmitted the virus to all or most of the quail in each animal room (6/6, 6/6 and 5/6) by the end of the experimental period, as determined by seroconversion and/or viral RNAshedding. …

Predicting Consistent Foraging Ecologies Of Migrating Waterbirds: Using Stable Isotope And Parasite Measurements As Indicators Of Landscape Use, Kate L. Sheehan, Brian S. Dorr, Stephen A. Clements, Terrel W. Christie, Katie Hanson-Dorr, Scott A. Rush, J. Brian Davis

United States Department of Agriculture Wildlife Services: Staff Publications

The emergence of novel human pathogens is frequently linked with zoonotic events and human-wildlife interactions that promote disease transmission. Consequently, surveillance of wildlife populations for candidate diseases that could spread to humans is beneficial, but requires widespread collections of numerous samples. A legitimate means to acquire large sample sizes of waterfowl is through cooperation between researchers and hunters, who also work in concert with natural resource managers, landowners, and agricultural entities -e.g., aquaculture facilities. In addition to understanding the occurrence and spread of parasites and pathogens by birds, these samples can be used to answer questions about the ecology of …

Social Learning Of Avoidance Behaviors: Trap Aversion In Captive Coyotes, Julie Young, Jeffrey T. Schultz, Buck Jolley, Nekol Basili, John P. Draper

United States Department of Agriculture Wildlife Services: Staff Publications

Social learning can help animals gain knowledge rapidly and may enhance survival. In species that are subjected to capture in foothold traps and then lethally removed, such as the coyote (Canis latrans), learning to avoid traps is critical to survival. Here, we tested social learning of trap avoidance behavior in three experimental scenarios with captive coyotes. In the first experiment, coyotes observed an unfamiliar coyote get captured in a foothold trap (i.e., demonstrator) or did not observe a demonstrator and were therefore naïve to traps. The coyotes that observed a demonstrator showed similar latencies to approach the trap …

Transverse Oscillating Bubble Enhanced Laser‑Driven Betatron X‑Ray Radiation Generation, Rafal Rakowski, Ping Zhang, Kyle Jensen, Brendan Kettle, Tim Kawamoto, Sudeep Banerjee, Colton Fruhling, Grigory Golovin, Daniel Haden, Matthew S. Robinson, Donald Umstadter, Bradley A. Shadwick, Matthias Fuchs

Department of Physics and Astronomy: Faculty Publications

Ultrafast high-brightness X-ray pulses have proven invaluable for a broad range of research. Such pulses are typically generated via synchrotron emission from relativistic electron bunches using large-scale facilities. Recently, significantly more compact X-ray sources based on laser-wakefield accelerated (LWFA) electron beams have been demonstrated. In particular, laser-driven sources, where the radiation is generated by transverse oscillations of electrons within the plasma accelerator structure (so-called betatron oscillations) can generate highly-brilliant ultrashort X-ray pulses using a comparably simple setup. Here, we experimentally demonstrate a method to markedly enhance the parameters of LWFA-driven betatron X-ray emission in a proof-of-principle experiment. We show a …

For many avian species, spatial migration patterns remain largely undescribed, especially across hemispheric extents. Recent advancements in tracking technologies and high-resolution species distribution models (i.e., eBird Status and Trends products) provide new insights into migratory bird movements and offer a promising opportunity for integrating independent data sources to describe avian migration. Here, we present a three-stage modeling framework for estimating spatial patterns of avian migration. First, we integrate tracking and band re-encounter data to quantify migratory connectivity, defined as the relative proportions of individuals migrating between breeding and nonbreeding regions. Next, we use estimated connectivity proportions along with eBird occurrence …

Summer Habitat Use And Movements Of Invasive Wild Pigs (Sus Scrofa) In Canadian Agro-Ecosystems, Corey J. Kramer, Melanie R. Boudreau, Ryan S. Miller, Ryan Powers, Kurt C. Vercauteren, Ryan K. Brook

United States Department of Agriculture Wildlife Services: Staff Publications

Resource selection informs understanding of a species’ ecology and is especially pertinent for invasive species. Since introduced to Canada, wild pigs (Sus scrofa Linnaeus, 1978) remain understudied despite recognized negative impacts on native and agricultural systems globally. Elsewhere in North America, pigs typically use forests and forage in agricultural crops. We hypothesized Canadian wild pigs would behave similarly, and using GPS locations from 15 individuals, we examined diel and seasonal resource selection and movement in the Canadian prairie region. Forests were predominately selected during the day, while corn (Zea mays L.), oilseeds, and wheat (Triticum aestivum L.) …
