Bark-Foragers May Use Artificially Created Holes In Trees As A Foraging Cue, Ruby L. Hammond, Yazhmin A. Dozal, Tad C. Theimer

Arizona Birds

Little is known about cues used by insectivorous bark-foraging birds to locate prey. Because vision is thought to be the primary sensory system used by many avifauna to perceive the environment, we conducted an experiment to assess if insectivorous bark-foragers in northern Arizona forests used holes in trees as foraging cues. We set up 20 experimental stations, each consisting of a pair of equally sized ponderosa pines (Pinus ponderosa) that had no previous holes created by foraging woodpeckers or emergent boring-beetles. For each pair of trees, we drilled holes into one of the trees (treatment tree) and did not drill …

Effects Of Slope Upon Hind Limb Kinematics In Chukar Partridge (Alectoris Chukar), Anna T. Kenney

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Ground dwelling birds must scale all kinds of complex terrain in order to survive in their natural environments. For instance, Alectoris chukar live on steep hillsides with slopes of up to 60° or 172.3% slope. We undertook the present study to improve understanding of how birds successfully traverse such complex terrain. Using a high speed camera, we analyzed the hind limb kinematics of chukars during normal locomotion on a 10° and 35° incline, decline, and level slope. We compared the data collected from the video recordings, which we had used to identify and digitize the bony landmarks, between all conditions. …

Sediment Microbiomes Associated With Critical Habitat Of The Juvenile American Horseshoe Crab; Limulus Polyphemus, J. Petersen, Christina P. Colon, J. L. Joyner

Publications and Research

Plumb Beach, Brooklyn, New York in USA is an important horseshoe crab breeding and nursery ground that has experienced substantial anthropogenic influence, including pollution, erosion and subsequent restoration. Since little is known about the relationship between sediment microbial communities and juvenile horseshoe crab survival, next generation sequencing was used to characterize and compare the sediment microbiome of three distinct areas of Plumb Beach:- a tidal creek with abundant juveniles, East Beach with moderate number of juveniles, and West Beach- a highly disturbed area where juvenile crabs are rarely seen. The microbiome of juvenile crab intestinal content (both dissected gut content …

The Brooklyn Papyrus is an Egyptian medical treatise on the subject of snakebite cures. It is a part of the Brooklyn Museum’s Charles Edwin Wilbour collection (47.218.48 and 47.218.85). In the 1960s, the papyrus was translated into French by Egyptologist Serge Sauneron. This research paper includes the first full translation of the Brooklyn Papyrus, as well as an introductory essay, which analyzes the structural and religious elements of the work. It also compares the Brooklyn Papyrus to another notable work on snakebites, Nicander of Colophon’s Theriaca.

Eighteen Is Not A Magic Number: Why The Eighth Amendment Requires Protection For Youth Aged Eighteen To Twenty-Five, Tirza A. Mullin

University of Michigan Journal of Law Reform

The Eighth Amendment protects a criminal defendant’s right to be free from cruel and unusual punishment. This Note argues that any punishment of eighteen- to twenty-five-year-olds is cruel and unusual without considering their youthfulness at every stage of the criminal process, and that it is unconstitutional under the Eighth Amendment for these youths to be automatically treated as fully-developed adults. This Note will explore in depth how juveniles differ from adults, both socially and scientifically, and how the criminal justice system fails every youth aged eighteen- to twenty-five by subjecting them to criminal, rather than juvenile, court without considering their …

Research Publications (2016 to 2020)

A new high γ-aminobutyric acid (GABA) producing strain of Bacillus cereus was successfully isolated from soy sauce moromi. This B. cereus strain named KBC shared similar morphological characteristics (Gram-positive, rod-shaped) with the reference B. cereus. 16S rRNA sequence of B. cereus KBC was found to be 99% similar with B. cereus strain OPWW1 under phylogenetic tree analysis. B. cereus KBC cultivated in unoptimized conditions using De Man, Rogosa, Sharpe (MRS) broth was capable of producing 523.74 mg L-1 of GABA within five days of the cultivation period. By using response surface methodology (RSM), pH level, monosodium glutamate (MSG) concentration and …

Flipping The Script: Developing An Intertextual Dialogue For Dolphin Advocacy In The Cove, Katherine D. Lind

Communication Studies Faculty Works

Dolphins and other cetaceans (marine mammals) have seen a surge of environmental advocacy in the decade since The Cove (2009) emerged. Drawing upon Western popular culture texts such as the popular film and television series, Flipper (1963), The Cove seeks to flip or reframe our cultural understanding of dolphins from friends to victims in need of help. In this essay, I argue that The Cove is an exemplar eco-doc that employs an intertextual dialogue to facilitate a multi-media outreach campaign that changed public perception of dolphins and lead to dolphin advocacy efforts. By analyzing how The Cove incorporates and challenges …

Comparison Of Wetland Restoration Techniques In And Around Turnbull National Wildlife Refuge, Cheney, Wa, Jade S. Clinkenbeard

EWU Masters Thesis Collection

Throughout the West, wetlands have been drained or filled in for agricultural or urban uses. Staff at Turnbull National Wildlife Refuge (TNWR) in Cheney work with local landowners to restore wetlands through excavation or flooding techniques. Unfortunately, TNWR staff cannot evaluate the wetlands to determine which technique is most successful. This thesis project compared the macroinvertebrate and plant communities and the limnological features of wetlands restored through excavation and flooding with those of unaltered, reference wetlands on TNWR. I hypothesized that the reference wetlands would hold water longest and would have higher plant diversity and macroinvertebrate diversity and abundance than …

The Reel Truth: The Importance Of Historical Accuracy In Film, Kyle A. Jenkins

EWU Masters Thesis Collection

The first goal of this project is to build a case that historical accuracy in film is an especially important criteria when teaching using film, and that educators and their students should be able to discuss any historical inaccuracies in a way that does not diminish enjoyment of the film. Aside from students, there should also be an expectation from the general populous that when a film claims to be historically accurate its inaccuracies should not be harmful to the overall conversation. Secondly, this project will attempt to build criteria for critiquing and analyzing a film based on balanced criteria …

Helicobacter Pylori Gene Regulation By Virulence Region Located Srnas, Veronica Janette Albrecht

EWU Masters Thesis Collection

Approximately 50% of the human population is infected with Helicobacter pylori, which can lead to gastrointestinal diseases such as ulcers and gastric adenocarcinoma. Helicobacter pylori strains are genetically variable, and some contain a DNA region called the cytotoxin associated gene pathogenicity island (cagPAI) that encodes virulence factors. Gastrointestinal disease associated with H. pylori are more likely to occur in infections with cagPAI positive strains. Helicobacter pylori has few known transcriptional regulators, but still must regulate expression to survive a constantly changing environment. A mechanism to facilitate this regulation was revealed in a transcriptome analysis conducted by Sharma et al. (2010) …

Impact Of Chytrid Fungus Pathogen On The Skin Microbiome Of Frogs In Northern Idaho And Turnbull National Wildlife Refuge, Washington, Philip M. Campos

EWU Masters Thesis Collection

Amphibians worldwide are under threat from the infectious disease chytridiomycosis, which is caused by the chytrid fungus Batrachochytrium dendrobatidis (Bd). Bd is associated with the population declines of an estimated 501 species, 90 of which are presumed or confirmed extinct, making this the greatest documented loss of biodiversity attributed to a disease. Researching the amphibian skin microbiome may provide solutions to conservation of amphibians. Two main relationships have been observed between Bd and the microbiome: 1) bacteria producing antifungal metabolites can inhibit Bd and improve survival against the disease and 2) infection by Bd is believed to affect the composition …

Kinetics Of Notch Signaling During Osteoclastogenesis, Amber Larissa Framstad

EWU Masters Thesis Collection

Bone remodeling, the process of removing and replacing damaged bone matrix, is a dynamic physiological process essential to maintaining bone composition and integrity. Improper coordination of resorption and formation can lead to pathologic changes in bone composition and quality, as is seen in osteoporosis, a bone disorder most seen in post-metapausal women attributed to decreased estrogen levels. The Notch signal pathway is a highly conserved direct cell communication pathway known to regulate cell proliferation, differentiation and survival in many cell types including the differentiation of osteoclasts from bone marrow macrophages (BMMs). Osteoclastogenesis is initiated in BMMs by receptor activator of …

Measuring Variation In Body Morphology And Life History Traits In Brook Stickleback (Culaea Inconstans), Eastern Washington, Usa, Lily Crytser

EWU Masters Thesis Collection

For freshwater ecosystems, invasive species are considered a major threat to biodiversity, and pose a challenge to those attempting to advance management strategies aimed at conserving natural populations. An invasive species’ ability to successfully invade a new ecosystem may be influenced by phenotypic plasticity, flexibility of life history traits, and the ability to migrate/disperse, among other factors. Brook stickleback (Culaea inconstans) have been a concern in eastern Washington since 1999 when they were discovered in water bodies on Turnbull National Wildlife Refuge. The purpose of this project was to describe potential variation in body morphology traits between systems that differed …

Expression And Functional Sialome Of Triatomines, Insect Vectors Of Chagas Disease, Maria Tays Mendes

Open Access Theses & Dissertations

Triatomines are blood-sucking arthropods that transmit Trypanosoma cruzi, the etiologic agent of Chagas disease (ChD). Triatomines use bioactive molecules in the saliva for successful blood feeding and to evade the hemostatic and immune defense system of the hosts. Knowing the saliva composition could be useful for a better understanding which and how insect-derived molecules might influence host-parasite interactions. Previous studies have shown that some saliva-derived proteins and lipids can modulate the host immune system and increase T. cruzi infection. We hypothesize that the triatomine saliva contains a great diversity of lipids and proteins that can modulate the mammalian host immune …

Burning, Nicolas Cooper

Open Access Theses & Dissertations

Burning is a book of poetry about occult magic, the Catholic eye, the mind jewel, and the color of my skin under the summer sun. It is about my meditations in the shade under desert trees and the visions I had there about access, love, and social class. Burning is the flaming desire inside of me for success and recognition, and yet at the same time homage to the Zen Buddhist precepts of non-attachment and acceptance. It is my thirsting for the lost américa's touch somewhere between endless sands and yellow-painted concrete, about my parallel aspirations for poetic duende and …

Toward Automated Region Detection & Parcellation Of Rat Brain Tissue Images, Alexandro Arnal

Open Access Theses & Dissertations

People who analyze images of biological tissue often rely on segmentation of structures as a preliminary step. In particular, laboratories studying the rat brain manually delineate brain regions to position scientific findings on a brain atlas to propose hypotheses about the rat brain, and ultimately, the human brain. Our work intersects with the preliminary step of delineating regions in images of brain tissue via computational methods.

We investigate pixel-wise classification or segmentation of brain regions using ten histological images of brain tissue sections stained for Nissl substance, and two deep learning models: U-Net and Tile2Vec. Our goal is to assess …

Validity Of A Portable X-Ray Fluorescence Device For Analyzing Field Dust Wipe Samples For Lead, Alexander Boakye Obeng

Open Access Theses & Dissertations

Background and Significance. Interior dust lead loadings on floors and windowsills are reliable predictors of a child’s blood lead level and an important predictor in “clearance testing” of residences. The traditional method of determining dust lead levels on surfaces is to send dust wipe samples to a laboratory for analysis. These laboratory analyses are expensive and analysis reports typically take up to 2 weeks to complete. The portable X-ray fluorescence device has been touted as a technique that can provide fast, accurate, and precise results regarding the presence of dust lead hazards in residences but needs to be further evaluated …

Cop Fragility And Blue Lives Matter, Frank Rudy Cooper

Scholarly Works

There is a new police criticism. Numerous high-profile police killings of unarmed blacks between 2012–2016 sparked the movements that came to be known as Black Lives Matter, #SayHerName, and so on. That criticism merges race-based activism with intersectional concerns about violence against women, including trans women.

There is also a new police resistance to criticism. It fits within the tradition of the “Blue Wall of Silence,” but also includes a new pro-police movement known as Blue Lives Matter. The Blue Lives Matter movement makes the dubious claim that there is a war on police and counter attacks by calling for …

The Role Of Warm, Dry Summers And Variation In Snowpack On Phytoplankton Dynamics In Mountain Lakes, Isabella A. Olesky, Whitney S. Beck, Roderick W. Lammers, Cara E. Steger, Codie Wilson, Kyle R. Christianson, Kim Vincent, Gunnar Forrest Johnson, Pieter T.J. Johnson, Jill S. Baron

Geology Faculty Publications and Presentations

Climate change is altering biogeochemical, metabolic, and ecological functions in lakes across the globe. Historically, mountain lakes in temperate regions have been unproductive because of brief ice-free seasons, a snowmelt-driven hydrograph, cold temperatures, and steep topography with low vegetation and soil cover. We tested the relative importance of winter and summer weather, watershed characteristics, and water chemistry as drivers of phytoplankton dynamics. Using boosted regression tree models for 28 mountain lakes in Colorado, we examined regional, intraseasonal, and interannual drivers of variability in chlorophyll a as a proxy for lake phytoplankton. Phytoplankton biomass was inversely related to the maximum snow …

The Professional Responsibility Case For Valid And Nondiscriminatory Bar Exams, Joan W. Howarth

Scholarly Works

Title VII protects against workplace discrimination in part through the scrutiny of employment tests whose results differ based on race, gender, or ethnicity. Such tests are said to have a disparate impact, and their use is illegal unless their validity can be established. Validity means that the test is job-related and measures what it purports to measure. Further, under Title VII, even a valid employment test with a disparate impact could be struck down if less discriminatory alternatives exist.

Licensing tests, including bar exams, have been found to be outside these Title VII protections. But the nondiscrimination values that animate …
