Sturm College of Law: Faculty Scholarship

This article proposes that law students, legal educators, and lawyers will benefit from developing their neuro-intelligence, as well as their understanding of the impact of emotion and stress on performance, and the how building mental strength can empower their professional and personal lives. With greater neuro-intelligence, individuals can improve well-being and performance, and organizations can leverage healthy human beings to enhance capacity and innovation.

Irruptions: Evidence For Breeding Season Habitat Limitation In Piping Plover (Charadrius Melodus), Samantha Robinson, James Fraser, Daniel Catlin, Sarah Karpanty, Jon Altman, Ruth Boettcher, Kevin Holcomb, Coral Huber, Kelsi Hunt, Alexandra Wilke

United States Army Corps of Engineers, Omaha District

Effective management of wildlife populations requires identification of the factors limiting their growth. The Piping Plover (Charadrius melodus) is an imperiled, disturbance-dependent, shorebird species that nests on broad, sparsely vegetated beaches, sandbars, and lakeshores. In areas minimally affected by human use, plover habitat loss occurs through vegetation encroachment and erosion. Alternatively, habitat availability may be increased by sand deposition caused by storm- or flood-induced sediment transport or scouring that removes vegetation, or by receding lake levels. To test the hypothesis that plover populations are limited by available breeding habitat, we estimated the amount of habitat available before and after four …

Urease Is An Essential Component Of The Acid Response Network Of Staphylococcus Aureus And Is Required For A Persistent Murine Kidney Infection, Chunyi Zhou, Fatema Bhinderwala, Mckenzie K. Lehman, Vinai Chittezham Thomas, Sujata S. Chaudhari, Kelsey J. Yamada, Kirk W. Foster, Robert Powers, Tammy Kielian, Paul D. Fey

Journal Articles: Pathology and Microbiology

Staphylococcus aureus causes acute and chronic infections resulting in significant morbidity. Urease, an enzyme that generates NH3 and CO2 from urea, is key to pH homeostasis in bacterial pathogens under acidic stress and nitrogen limitation. However, the function of urease in S. aureus niche colonization and nitrogen metabolism has not been extensively studied. We discovered that urease is essential for pH homeostasis and viability in urea-rich environments under weak acid stress. The regulation of urease transcription by CcpA, Agr, and CodY was identified in this study, implying a complex network that controls urease expression in response to changes in metabolic …

Design And Characterization Of A Consensus Hemagglutinin Vaccine Immunogen Against H3 Influenza A Viruses Of Swine, Haiyan Sun, Jung-Hyang Sur, Sarah Vitosh-Sillman, David J. Steffen, Hiep Vu

Nebraska Center for Virology: Faculty Publications

The substantial genetic diversity exhibited by influenza A viruses of swine (IAV-S) represents the main challenge for the development of a broadly protective vaccine against this important pathogen. The consensus vaccine immunogen has proven an effective vaccinology approach to overcome the extraordinary genetic diversity of RNA viruses. In this project, we sought to determine if a consensus IAV-S hemagglutinin (HA) immunogen would elicit broadly protective immunity in pigs. To address this question, a consensus HA gene (designated H3-CON.1) was generated from a set of 1,112 H3 sequences of IAV-S recorded in GenBank from 2011 to 2015. The consensus HA gene …

Global Spatial Risk Assessment Of Sharks Under The Footprint Of Fisheries, Nuno Queiroz, Bradley M. Wetherbee, Et Al

Biological Sciences Faculty Publications

Effective ocean management and the conservation of highly migratory species depend on resolving the overlap between animal movements and distributions, and fishing effort. However, this information is lacking at a global scale. Here we show, using a big-data approach that combines satellite-tracked movements of pelagic sharks and global fishing fleets, that 24% of the mean monthly space used by sharks falls under the footprint of pelagic longline fisheries. Space-use hotspots of commercially valuable sharks and of internationally protected species had the highest overlap with longlines (up to 76% and 64%, respectively), and were also associated with significant increases in fishing …

Vulnerability Of Resource Users In Louisiana’S Oyster Fishery To Environmental Hazards, Austin T. Humphries, Lauren I. Josephs, Megan K. La Peyre, Steven Hall, Rachel Dowty Beech

Fisheries, Animal and Veterinary Sciences Faculty Publications

Knowledge of vulnerability provides the foundation for developing actions that minimize impacts on people while maximizing the sustainability of ecosystem goods and services. As a result, it is becoming increasingly important to determine how resource-dependent people are vulnerable to environmental hazards. This idea is particularly true in coastal Louisiana, USA, where the current era of rapid land loss has the potential to undermine oyster fisheries. However, little is known about how such environmental change might differentially affect resource users and stakeholders. We examined social components of vulnerability to environmental hazards using indicators of susceptibility and adaptive capacity within the oyster …

Complex Transboundary Movements Of Marine Megafauna In The Western Indian Ocean, Amanda N. Barkley, Matthew Gollock, Melita Samoilys, Fiona Llewellyn, Mahmood Shivji, Bradley M. Wetherbee, Nigel E. Hussey

Biological Sciences Faculty Publications

Transboundary marine species have an increased risk of overexploitation as management regimes and enforcement can vary among states. The complex geopolitical layout of exclusive economic zones (EEZs) in the Western Indian Ocean (WIO) introduces the potential for migratory species to cross multiple boundaries, consequently a lack of scientific data could complicate regional management. In the current study, we highlight both the relative lack of spatial data available in the WIO, and the prevalence of transboundary movements in species that have previously been studied in the region. Five tiger sharks Galeocerdo cuvier were tracked with near real‐time positioning (SPOT) satellite tags …

Backward Bifurcation, Oscillations And Chaos In An Eco-Epidemiological Model With Fear Effect, Amar Sha, Sudip Samanta, Maia Martcheva, Joydev Chattopadhyay

Journal Articles

This paper considers an eco-epidemiological model with disease in the prey population. The disease in the prey divides the total prey population into two subclasses, susceptible prey and infected prey. The model also incorporates fear of predator that reduces the growth rate of the prey population. Furthermore, fear of predator lowers the activity of the prey population, which reduces the disease transmission. The model is well-posed with bounded solutions. It has an extinction equilibrium, susceptible prey equilibrium, susceptible prey-predator equilibrium, and coexistence equilibria. Conditions for local stability of equilibria are established. The model exhibits fear- induced backward bifurcation and bistability. …

Repeated Neonatal Isoflurane Exposures In The Mouse Induce Apoptotic Degenerative Changes In The Brain And Relatively Mild Long-Term Behavioral Deficits, George Taylor, Susan Maloney, Carla Yuede, Catherine Creeley, Sasha Williams, Jacob Hufman, Kevin Noguchi, David Wozniak

Psychology Faculty Works

Epidemiological studies suggest exposures to anesthetic agents and/or sedative drugs (AASDs) in children under three years old, or pregnant women during the third trimester, may adversely afect brain development. Evidence suggests lengthy or repeated AASD exposures are associated with increased risk of neurobehavioral defcits. Animal models have been valuable in determining the type of acute damage in the developing brain induced by AASD exposures, as well as in elucidating long-term functional consequences. Few studies examining very early exposure to AASDs suggest this may be a critical period for inducing long-term functional consequences, but the impact of repeated exposures at these …

Nature Of The Crescent: Humans And The Natural World In Genesis 1-11 And Mesopotamian Mythology, Bryton A. Smith

Honors Papers

This capstone thesis examines the human-nature relationship in the Genesis primeval history (Gen. 1-11) and compares it to the human-nature relationship in the Mesopotamian Enuma Elish, Atrahasis, and Epic of Gilgamesh myths. Despite common threads running in the two sources of mythology, I argue that Genesis is the only text that portrays humans in a religiously and royally authoritative position that includes responsibility for nature. To clarify, modern Jewish or Christian thought on Genesis in relation to the environment is not the focus of this study. Instead, this study examines Gen. 1-11 in the context of the ancient Near East, …

Just Punishment?: The Epistemic And Affective Investments In Carceral Feminism, Tess Joseph

Honors Papers

This thesis draws upon recent works in feminist theory, epistemological theory, affect theory, and abolitionist theory to critically engage with contemporary U.S. forms of “carceral feminism,” Elizabeth Bernstein’s (2010) concept that describes the recasting of feminist politics in carceral terms. I expand upon Bernstein to contend that we must direct attention to our epistemic and affective conditions to understand our investments in carceral feminism.

I begin by mapping the origins of carceral feminism, first tracing its history through a discussion of the initial iterations of colonialism and enslavement. Turning to a more recent timeline of the mainstream feminist anti-violence movement—a …

Powerful Women Writers In Eighteenth Century Germany: A Comparison Of The Two German Women Writers Sophie Von La Roche (Gutermann) And Dorothea Schlegel (Mendelssohn), Exploring Their Upbringing, Marriages, Love, Literary Works, And Social Atmospheres, Miriam Ute Powers

Browse all Theses and Dissertations

This thesis explores the status of German women writers in the 18th century during the era of Enlightenment and Romanticism. I will examine the philosophical ideas and beliefs during these times, and the impact these ideas had on La Roche and Schlegel specifically, as well as society as a whole. While studying the life style, upbringing, and the most important literary works of the two women writers, I will show the advancements made by them towards greater autonomy for other women writers emphasizing their courage, alongside the hardship they often endured. Seeking greater recognition and freedom from male tutelage, La …

Lights, Camera, Path Splitter: A New Approach For Truly Simultaneous Dual Optical Mapping Of The Heart With A Single Camera., Rafael Jaimes, Damon Mccullough, Bryan Siegel, Luther Swift, James Hiebert, Daniel Mclnerney, Nikki Gillum Posnack

Pediatrics Faculty Publications

Background: Optical mapping of transmembrane voltage and intracellular calcium is a powerful tool for investigating cardiac physiology and pathophysiology. However, simultaneous dual mapping of two fluorescent probes remains technically challenging. We introduce a novel, easy-to-use approach that requires a path splitter, single camera and excitation light to simultaneously acquire voltage and calcium signals from whole heart preparations, which can be applied to other physiological models - including neurons and isolated cardiomyocytes.

Results: Complementary probes were selected that could be excited with a single wavelength light source. Langendorff-perfused hearts (rat, swine) were stained and imaged using a sCMOS camera outfitted with …

Enhancing Environmental Staff Cleaning Process And Adenosine Triphosphate (Atp), Rochelle D. Bello

Regis University Student Publications (comprehensive collection)

Clostridium difficile (C. difficile) has become the most common microbial cause of healthcareassociated infections (HAI) in U.S. hospitals and costs billions of dollars each year in excess of health care costs for acute care facilities alone (Centers for Disease Control and Prevention [CDC], 2015, para. 2). Inadequate cleaning of contaminated surfaces in the hospital environment may lead to an HAI. Potential barriers related to environmental cleaning of C. difficile infected rooms were identified at a small safety net hospital. The investigator used a convenience sample of 12 environmental staff (EVS) and a quasi-experimental pre-posttest design, to explore whether or not …

Trade-Offs Relating To Grassland And Forest Mine Reclamation Approaches In The Central Appalachian Region And Implications For The Songbird Community, Eric L. Margenau, Petra B. Wood, Cathy A. Weakland, Donald J. Brown

Faculty & Staff Scholarship

Surface mining in the Appalachian region (USA) converts large areas of mature forest to early successional habitat. This shift in landscape structure has the potential to reduce habitat availability and suitability for forest-dwelling songbirds by reducing and fragmenting mature forest, but also to increase habitat availability for grassland- and shrubland-associated songbirds. We examined the influence of mountaintop mining/valley fill (MTMVF) reclamation habitats (grassland, shrubland, and remnant forest) on songbird community composition and abundance at three former MTMVF mines in southwestern West Virginia, relative to intact forest. We quantified the songbird community in 1999 and 2000 using point counts arranged throughout …

The Universal Image: Are Mental Images Formed Using Prototypes?, G. Adam Martz

Undergraduate Psychology Research Methods Journal

This study explores the formation of mental images. Two opposing theories are reviewed concerning what influences which specific examples we choose to picture when supplied with vague concepts. The more prominent “descriptive theory” assumes that mental images are formed using the same methods of categorization and recall that other mental processes follow. Due to the descriptive theory’s similarity to the linguistic concept of prototypicality, the mental images formed by twelve participants are examined to determine whether linguistic prototypicality or our personal preferences have a higher impact in how mental images develop. A wide degree of variance in how participants perceived …

Hearing Studies In Old Mice: The Effect Of Pre-Pulse Inhibition On The Acoustic Startle Response, Ashley B. Hillyard, Nicolette S. Chuss

Senior Honors Projects, 2010-2019

The purpose of this study pertains to hearing in the species Peromyscus maniculatus (deer mice) — specifically their responses to a startling sound. Approximately seven mice were tested between four and five years of age, approaching the lifespan of this species. By means of an accelerometer, which measures a reflexive, motor response, the mice were presented with an acoustic startle-eliciting stimulus (SES) — that is a loud, startling, unexpected sound. During the study, the mice were also presented with a softer, less-intense stimulus — known as a pre-pulse — slightly before the more intense sound. This pre-pulse stimulus was in …

The Microbial Loop Concept: A History, 1930–1974, Peter J. Le B. Williams, Hugh W. Ducklow

Journal of Marine Research

The microbial loop as a leading concept in marine microbiology gained wide recognition in the 1980s, but it has roots extending back to the 1930s when microbiologists first began to take a more dynamic approach to investigating the roles of bacteria in ocean food webs and biogeochemical cycles. Here we present a history of the microbial loop concept with emphasis on the period starting in 1930, when marine bacteriologists in Russia and the West began to study explicitly the roles of marine bacteria in the sea. Selman Waksman at Woods Hole and Claude ZoBell at La Jolla relied on colony …

Characterization Of Cytosolic Sulfotransferase Expression And Regulation In Human Liver And Intestine, Sarah Talal Dubaisi

Wayne State University Dissertations

SULTs are conjugation enzymes that can modify the activity of a myriad of foreign and endogenous molecules. SULT expression was detected in various human tissues, including liver, small intestine, and colon. There are 13 human SULT genes that are classified into 4 families, SULT1, SULT2, SULT4, and SULT6. In humans, SULT1 and SULT2 families include 11 genes that are further divided into 6 subfamilies. In addition to their role in xenobiotic detoxification and regulation of physiological processes, SULT enzymes were implicated in the bioactivation of procarcinogens. Previous studies detected the expression of most SULT1 and SULT2 enzymes during early development, …

Assessing The Effectiveness Of Core-Shamanism On A Group Of Westerners: A Brief Research Report, Joanic Masson, Yannick Gounden, Charlemagne Simplice Moukouta, Amal Bernoussi, Antoine Saurat

International Journal of Transpersonal Studies

A study was conducted on Western adults who participated in a group undergoing initiation into therapeutic shamanism. It investigated how shamanic work could be a factor triggering changes in persons who never had been previously immersed in such a tradition. Five groups, each composed of six people for a total of 30 participants, met eight times over a period of four months. Analyzing questions asked of the 27 who completed the program resulted in the following identified themes: experiences of the group, trust in the shamanic practitioner, raised awareness of their feeling states, experiences of the shamanic journeys, understanding of …

The Meso-American Goddess Coatlicue: Too Terrifying For The Spaniards, Stanley Krippner

International Journal of Transpersonal Studies

The Coatlicue myth of Meso-America is currently represented by the huge basalt statue of the Earth goddess on display at the National Museum of Anthropology and History in Mexico City. The Spanish invaders who unearthed the statue promptly reburied the goddess, who did not again see the light of day until 1803. Today she commands attention both as a singular work of art and as a reminder that Earth is, at the same time, a loving mother and an insatiable monster, one who ultimately devours those to whom she has given birth. From a postmodern stance, myths are

Desertification Assessment Using Medalus Method And Gis Techniques In North America Arid Environments, Essdik Bashir Habashi

Master's Theses

Desertification is a massive issue that affects many countries that have dry climates. The impacts of this phenomenon threaten the sustainability of natural resources, as well as agricultural, water, and food resources. Several factors that affect directly or indirectly desertification and making it worse are population growth, climate change, deforestation, overgrazing, natural disaster, and urbanization and other types of land development. This thesis research evaluated the desertification index in three counties in California State and three counties in New Mexico State by using the MEDALUS model (Mediterranean Desertification and Land Use) within a geographic information system (GIS). The model includes …

Aging And Visual Spatial Integration, Alexia J. Higginbotham

Masters Theses & Specialist Projects

The current study evaluated the ability of 20 younger and 20 older adults to discriminate shapes depicted by Glass patterns. On any given trial, observers identified a particular pattern as either possessing a radial or concentric organization. Detecting a shape defined by a Glass pattern requires the successful detection of the orientations of its constituent local dipoles. In addition, long-range processes are needed to integrate the spatially separated dipoles into perceivable contours that have a particular (e.g., radial or concentric) organization. In the current experiment, the shapes were defined by either 40 or 200 oriented dipoles spread over an area …
