The Gundlach Collection : A Study Of Projectile Points From The Albeni Falls Reservoir, Jeffrey Cortlund Johnson

EWU Masters Thesis Collection

A formerly private collection of projectile points belonging to the Kalispel Tribe of Indians Cultural Resources Program provides stylistic, temporal, and geographic information for sites in the Albeni Falls Reservoir, Idaho. Specifically, there are 462 artifacts from 24 sites based on information derived from the collector’s and tribal archaeologist’s notes. Depositional information is unknown and artifacts are as surface finds. Analyses performed in this study include the morphological and technological dimensions of style, geographic and temporal distribution of artifacts by site, comparative results of obsidian x-ray fluorescence, and high-resolution photography. The results demonstrate the collection as a pragmatic dataset yielding …

The Source Of Excess Nutrients To Pine Draw, Turnbull National Wildlife Refuge, Henry Price

EWU Masters Thesis Collection

Nitrogen and phosphorus are the most common limiting nutrients for biological activity in freshwater ecosystems. Applying inorganic nitrogen fertilizer has increased crop productivity but caused excess nitrogen inputs to the hydrosphere. Nitrate contamination is a worldwide environmental problem. The fate of nitrogen in ecosystems is variable based on land type and hydrogeological interactions. Excess nitrogen can be retained in soils, sequestered in stream organisms, denitrified or transported downstream. The goals of this study were to monitor nitrogen concentrations in Pine Draw, Turnbull National Wildlife Refuge (TNWR), Washington, U.S.A., and to determine the source of nitrogen loading. Pine Draw is unique …

Women And Technology In The Newsroom: Vision Or Reality From Data Journalism To The News Startup Era, Nik Usher

Communication: Faculty Scholarship

Journalism is now increasingly as technically inspired as it is editorially driven. From the rise of interactive journalists to product managers to user experience specialists, journalism in the places most likely to survive the economic fretful of the industry has moved closer to tech startup in culture and in practice. Some of the most promising new news startups, such as Buzzfeed and Vox, in fact, premise their identity as half-media and half-tech. In some cases, women are at the forefront as leaders in these newsrooms, but overall, demographics are not in their favor unless significant structural changes occur. Will what …

Meeting Place An Exhibition – And – Locating The Country: An Australian Bricoleuse’S Inquiry An Exegesis, Annette Nykiel

Theses: Doctorates and Masters

This practice-led PhD research investigated alternate forms of articulation to relate stories of place-making, as narrative or object, and added threads to the complex meshwork and herstory of the Country. The research was conducted in ‘The Country’, of the north-eastern Goldfields and Yalgorup Lakes in Western Australia. These two non-urban sites provided unique experiences of the bush, local people’s stories and understandings of time. The research investigated the implications of non-urban spaces as studios in relation to the concepts of place, time and narrative.

This research was, in part, experiential and drew on an absorbed embodied awareness of notions of …

An Integrated System To Design Machine Layouts For Modular Special Purpose Machines, Uday Hameed Farhan

Theses: Doctorates and Masters

This thesis introduces the development of an integrated system for the design of layouts for special purpose machines (SPMs). SPMs are capable of performing several machining operations (such as drilling, milling, and tapping) at the same time. They consist of elements that can be arranged in different layouts. Whilst this is a unique feature that makes SPMs modular, a high level of knowledge and experience is required to rearrange the SPM elements in different configurations, and also to select appropriate SPM elements when product demand changes and new layouts are required. In this research, an integrated system for SPM layout …

Using Agricultural Wastes To Treat Lead-Contaminated Water In Western Australia, Hanie Hashtroudi

Theses: Doctorates and Masters

Aqueous solutions are becoming increasingly contaminated in all parts of the world (2015). Heavy metals are toxic contaminants that are mainly distributed in urban stormwater run-off and industrial wastewaters as a result of some mining operations, electronic assembly planting, battery manufacturing, and etching operations (Kadirvelu et al. 2001). Pb (II) is a heavy metal that causes significant damage in the human body. Drinking lead-contaminated water even at low concentrations may cause lifethreatening conditions such as cancer, kidney damage, brain damage, and liver problems (El-Said 2010). Therefore, it is necessary to remove lead from aqueous solutions.

Several conventional physical, chemical, and …

Parasitaemia Data And Molecular Characterization Of Haemoproteus Catharti From New World Vultures (Cathartidae) Reveals A Novel Clade Of Haemosporida, Michael J. Yabsley, Ralph E.T. Vanstreels, Ellen S. Martinsen, Alexandra G. Wickson, Amanda E. Holland, Sonia M. Hernandez, Alec T. Thompson, Susan L. Perkins, Christopher A. Lawrence Bryan, Christopher A. Cleveland, Emily Jolly, Justin D. Brown, Dave Mcruer, Shannon Behmke, James C. Beasley

Faculty & Staff Scholarship

Background: New World vultures (Cathartiformes: Cathartidae) are obligate scavengers comprised of seven species in five genera throughout the Americas. Of these, turkey vultures (Cathartes aura) and black vultures (Coragyps atratus) are the most widespread and, although ecologically similar, have evolved differences in morphology, physiology, and behaviour. Three species of haemosporidians have been reported in New World vultures to date: Haemoproteus catharti, Leucocytozoon toddi and Plasmodium elongatum, although few studies have investigated haemosporidian parasites in this important group of species. In this study, morphological and molecular methods were used to investi- gate the epidemiology and molecular biology of haemosporidian parasites of …

Genetic Analyses Reveal Cryptic Introgression In Secretive Marsh Bird Populations, Stephanie S. Coster, Amy B. Welsh, Gary Costanzo, Sergio R. Harding, James T. Anderson, Susan B. Mcrae, Todd E. Katzner

Faculty & Staff Scholarship

Hybridization is common in bird populations but can be challenging for management, especially if one of the two parent species is of greater conservation concern than the other. King rails (Rallus elegans) and clapper rails (R. crepitans) are two marsh bird species with similar morphologies, behaviors, and overlapping distributions. The two species are found along a salinity gradient with the king rail in freshwater marshes and the clapper in estuarine marshes. However, this separation is not absolute; they are occasionally sympatric, and there are reports of interbreeding. In Virginia, USA, both king and clapper rails are …

Quantitative Acoustic Differentiation Of Cryptic Species Illustrated With King And Clapper Rails, Lydia L. Stiffler, Katie M. Schroeder, James T. Anderson, Susan B. Mcrae, Todd E. Katzner

Faculty & Staff Scholarship

Reliable species identification is vital for survey and monitoring programs. Recently, the development of digital technology for recording and analyzing vocalizations has assisted in acoustic surveying for cryptic, rare, or elusive species. However, the quan- titative tools that exist for species differentiation are still being refined. Using vocali- zations recorded in the course of ecological studies of a King Rail (Rallus elegans) and a Clapper Rail (Rallus crepitans) population, we assessed the accuracy and effective- ness of three parametric (logistic regression, discriminant function analysis, quadratic discriminant function analysis) and six nonparametric (support vector machine, CART, Random Forest, k-nearest neighbor, weighted …

Face Size Biases Emotion Judgment Through Eye Movement, Shuo Wang

Faculty & Staff Scholarship

Faces are the most commonly used stimuli to study emotions. Researchers often manipulate the emotion contents and facial features to study emotion judgment, but rarely manipulate low-level stimulus features such as face sizes. Here, I investigated whether a mere difference in face size would cause differences in emotion judgment. Subjects discriminated emotions in fear-happy morphed faces. When subjects viewed larger faces, they had an increased judgment of fear and showed a higher specificity in emotion judgment, compared to when they viewed smaller faces. Concurrent high-resolution eye tracking further provided mechanistic insights: subjects had more fixations onto the eyes when they …

Mammal Communities Are Larger And More Diverse In Moderately Developed Areas, Arielle Waldstein Parsons, Tavis Forrester, Megan C. Baker-Whatton, William J. Mcshea, Christopher T. Rota, Stephanie G. Schuttler, Joshua J. Millspaugh, Roland Kays

Faculty & Staff Scholarship

Developed areas are thought to have low species diversity, low animal abundance, few native predators, and thus low resilience and ecological function. Working with citizen scientist volunteers to survey mammals at 1427 sites across two development gradients (wild-rural-exurban- suburban-urban) and four plot types (large forests, small forest fragments, open areas and residential yards) in the eastern US, we show that developed areas actually had significantly higher or statistically similar mammalian occupancy, relative abundance, richness and diversity compared to wild areas. However, although some animals can thrive in suburbia, conservation of wild areas and preservation of green space within cities are …

Cluster-Based Network Proximities For Arbitrary Nodal Subsets, Kenneth S. Berenhaut, Peter S. Barr, Alyssa M. Kogel, Ryan L. Melvin

Faculty & Staff Scholarship

The concept of a cluster or community in a network context has been of considerable interest in a variety of settings in recent years. In this paper, employing random walks and geodesic distance, we introduce a unified measure of cluster-based proximity between nodes, relative to a given subset of interest. The inherent simplicity and informativeness of the approach could make it of value to researchers in a variety of scientific fields. Applicability is demonstrated via application to clustering for a number of existent data sets (including multipartite networks). We view community detection (i.e. when the full set of network nodes …

The Impact Of The 2014-2016 Ebola Epidemic On Sierra Leonean Immigrants In The United States, Daphne J. Cole

Open Access Dissertations

The 2014-2016 Ebola epidemic represented the largest outbreak in the history of the disease and it took a tremendous toll on the West African countries of Guinea, Liberia, and Sierra Leone who were impacted by a disease that had never been seen in their part of the world. While the epidemic significantly impacted those three nations, reported cases also spread to African countries such as Mali, Nigeria, and Senegal, as well as countries in the western world, such as Spain and the U.S. prior to the West African epidemic. Ebola was perceived in the U.S. as a distant threat dramatized …

Impacts Of Urbanization And Invasive Species On Foraging Behavior And Body Size In Anolis Sagrei, Zachary Chejanovski

Open Access Dissertations

Urbanization dramatically alters the abiotic and biotic environment of cities, favoring species that are pre-adapted or are able to adapt (e.g. through phenotypic plasticity or evolutionary mechanisms) to these novel conditions. While urbanization is widely considered one of the greatest threats to biodiversity worldwide, we still lack a general understanding of the mechanisms underlying organismal responses to human-induced rapid environmental change. The focus of this thesis was to examine how urbanization-induced changes in the abiotic and biotic environment influence the foraging behavior and body size of the brown anole, Anolis sagrei. In Chapter 1, we presented anoles from habitats …

Eastern Oyster Larval Transcriptomes In Response To Probiotic And Pathogenic Bacteria, Tejashree Modak

Open Access Dissertations

Oysters are described as keystone species serving an important ecological role. As filter-feeders they help in maintaining water quality. Oyster reefs provide refuge and support to different organisms. The eastern oyster, Crassostrea virginica, native to the East Coast of United States and Gulf of Mexico is a part of the rapidly growing aquaculture industry. Aquaculture production depends on a healthy and constant supply of oyster larvae that are provided by hatcheries. Several hatcheries on the east coast that provide C. virginica seed to oyster farms face significant losses owing to Vibrio infections causing massive larval mortalities. Use of antibiotics …

Compassion: Can Service Learning Make A Difference, And If So, How?, Edward Goldberg

Open Access Dissertations

The future of education is often framed in terms of bringing education into the second half of the 21^st century. Technology and along with it, faster and better ways to bring content to our students are important topics for discussion; but how our students treat each other and other members of their community is equally, if not more, important.

This study takes a look at how we may be able to encourage and foster compassion among our students. I wanted to know how compassionate thoughts and feelings develop following a service-learning experience focused on compassionate behavior. In this qualitative …

The Duty To Disobey Illegal Nuclear Strike Orders, Anthony J. Colangelo

Faculty Journal Articles and Book Chapters

This Article argues there is a legal duty to disobey illegal nuclear strike orders. Failure to carry out this duty may result in criminal and civil liability.Because nuclear weapons are quantitatively and qualitatively different from conventional weapons, typical legal calculations regulating their use under the laws of war or humanitarian law, as well as human rights law, change along with the change in weaponry. At least five “unique characteristics” of nuclear weapons ominously distinguish them from conventional weapons in ways that promise only to increase civilian death and suffering. First, quantitatively, the blast power, heat, and energy generated far outstrip …

Pluralism And Regulatory Response To The Sharing Economy, Erez Aloni

All Faculty Publications

Providers use platforms in dissimilar ways. Some providers create new capacity and designate it for exclusively commercial use via platforms. For example, a provider buys a car that serves predominantly for driving paying passengers, converts a standard residential rental to a short-term rental, or works full-time via a platform. Conversely, other providers leverage their idle capacity and monetize it (e.g., a provider uses the family car to drive platform passengers in the evenings). This chapter argues that the distinction between new and idle capacity is a fundamental concept that should guide regulation of activities in the platform economy. Creating new …

Analysis Of Atp-Dependent Chaperone Protein Interactions With Misfolded Proteins, Amyloids, And Aggregated Proteins, Shannon May

Open Access Dissertations

Protein aggregation occurs when proteins adopt non-native conformations, exposing hydrophobic surfaces due to misfolding. The exposed regions of two or more proteins associate to form amorphous deposits or highly ordered, stable fibrillar structures called amyloid aggregates. Within the cell, a robust network of proteins safeguard against protein misfolding and aggregation. This network is referred to as the proteostasis network and includes molecular chaperone proteins, co-chaperone proteins, and the ubiquitin proteasome system. Molecular chaperone proteins function in various cellular processes including intracellular transport, oligomeric assembly, and efficient protein folding. Moreover, molecular chaperones are required for folding denatured, misfolded, and de novo …

Mechanisms Of Individual Variation In Glucuronidation, Sulfonation, And Amidation: Bisphenol A And Bile Acids, Adam Michael Auclair

Open Access Dissertations

The role of conjugation of chemicals and endogenous compounds is an important mechanism in detoxification and metabolic signaling. Specifically, amidation, sulfonation, and glucuronidation are necessary functions of the human body. Exposure to environmental toxins such as bisphenols must be conjugated in order to be excreted from the body. Bisphenol A was originally developed as a synthetic estrogen, however later found use as a monomer within the plastics industry allowing for wide-spread exposure to BPA through food and drink containers. While most healthy individuals are capable of metabolizing and excreting bisphenol A, this metabolism can be impacted by diet and disease. …

Sleep Disturbances And Depression Severity In Patients With Parkinson’S Disease, Daniel Kay, Jared J. Tanner, Dawn Bowers

Faculty Publications

Objectives: Parkinson’s disease (PD) is a multisystem movement disorder associated with sleep disturbance and depression. Sleep disturbances and depression severity share a bidirectional association. This association may be greater in individuals who are more vulnerable to the deleterious consequences of sleep disturbance and depression severity. We investigated whether the association between sleep disturbances and depression severity is greater in patients with PD than in matched controls (MC).

Materials and Methods: The study sample (N = 98) included 50 patients with idiopathic PD and 48 age-, race-, sex-, and education-matched controls. Sleep disturbances were assessed using self-reported total sleep time (TST) …

Faculty Publications

Genetic test results have important implications for close family members. Indeterminate negative results are the most common outcome of BRCA1/2 muta-tion testing. Little is known about family members' understanding of indeterminate negative BRCA1/2 test results. The purpose of this mixed-methods study was to in-vestigate how daughters and sisters received and understood genetic test results as shared by their mothers or sisters. Participants included 81 women aged 40–74 with mothers or sisters previously diagnosed with breast cancer and who received inde-terminate negative BRCA1/2 test results. Participants had never been diagnosed with breast cancer nor received their own genetic testing or counseling. …

Climate Change Challenges For Land Conservation: Rethinking Conservation Easements, Strategies, And Tools, W. William Weeks, Jessica Owley, Federico Cheever, Adena R. Rissman, M. Rebecca Shaw, Barton H. Thompson

Articles by Maurer Faculty

Climate change has significant consequences for land conservation. Government agencies and nonprofit land trusts heavily rely on perpetual conservation easements. However, climate change and other dynamic landscape changes raise questions about the effectiveness and adaptability of permanent conservation instruments like conservation easements. Building upon a study of 269 conservation easements and interviews with seventy conservation-easement professionals in six different states, we examine the adaptability of conservation easements to climate change. We outline four potential approaches to enhance conservation outcomes under climate change: (1) shift land-acquisition priorities to account for potential climate-change impacts; (2) consider conservation tools other than perpetual conservation …

Debunked, Discredited, But Still Defended: Why Prosecutors Resist Challenges To Bad Science And Some Suggestions For Crafting Remedies For Wrongful Conviction Based On Changed Science, Aviva A. Orenstein

Articles by Maurer Faculty

Flawed science has significantly contributed to wrongful convictions. Courts struggle with how to address such convictions when the mistaken science (such as bogus expert claims about the differences between accidental fires and intentionally set ones) significantly affected the guilty verdict but there is no DNA evidence to directly exonerate the accused. My short piece explores why prosecutors often defend bad science. Mistakes in science tend to serve the prosecution, but there are other more subtle factors that explain prosecutors’ reluctance to address flawed forensic testimony. Such reluctance may arise from fondness for the status quo and a resistance to subverting …
