Brothers In Blood: The Significance Of Land And Loss In The Creation Of Jewish And Native American Ethnic And Religious Identity, Michael Eron Chaness

Dissertations - ALL

Volunteering at the Onondaga Nation School and collaborating with Chief Jacobs has exposed me to a new and subversive underbelly of American political and religious life. Working on sovereign Native land also provided valuable on the ground experience in Onondaga language and Haudenosaunee culture - food, humor, lacrosse, art, ceremony, government, education etc. Throughout my tenure at Onondaga I have used comparison as the backdrop for my experiences collaborating with Native peoples as well as the methodological backbone for this dissertation project.

My dissertation project, Brothers in Blood: the Significance of Land and Loss in the Creation of Jewish and …

Studies Of Cell Motility And Differentiation In Complex 3d In Vitro Microenvironment, Jing Wang

Dissertations - ALL

Cell behaviors, such as motility and differentiation, which are highly regulated by the complex 3D in vivo microenvironment, have been extensively studied in the past decades to better understand the mechanisms of development, disease, and healing. Due to the highly complex nature of the in vivo environment and limited resources and access to study cell behaviors in vivo, great efforts have been made to develop in vitro systems to mimic the in vivo microenvironment for a better understanding of cell-microenvironment interactions. However, most of the commonly used in vitro systems are static, which cannot mimic the dynamics of the microenvironment …

Murine Models Of Splenic Marginal Zone Lymphoma: A Role For Cav1?, Chelsey L. Patten, Christine E. Cutucache

Biology Faculty Publications

Dozens of murine models of indolent and aggressive B-cell lymphomas have been generated to-date. These include those manifesting chronic lymphocytic leukemia (CLL), diffuse large B-cell lymphoma (DLBCL) as well as xenografts of mantle cell lymphoma (MCL). These models have led to an improved understanding of disease etiology, B-cell biology, immunomodulation, and the importance of the tumor microenvironment. Despite these efforts in CLL, DLBCL, and MCL, considerably little progress toward a model of splenic marginal zone lymphoma (SMZL) has been accomplished. Herein, we describe the similarities and differences between CLL, MCL, and SMZL, and highlight effective murine models that mimic disease …

Assessing Data Quality In Citizen Science, Margaret Kosmala, Andrea Wiggins, Alexandra Swanson, Brooke Simmons

Information Systems and Quantitative Analysis Faculty Publications

Ecological and environmental citizen‐science projects have enormous potential to advance scientific knowledge, influence policy, and guide resource management by producing datasets that would otherwise be infeasible to generate. However, this potential can only be realized if the datasets are of high quality. While scientists are often skeptical of the ability of unpaid volunteers to produce accurate datasets, a growing body of publications clearly shows that diverse types of citizen‐science projects can produce data with accuracy equal to or surpassing that of professionals. Successful projects rely on a suite of methods to boost data accuracy and account for bias, including iterative …

Connected Vehicles At Signalized Intersections: Traffic Signal Timing Estimation And Optimization, S. Alireza Fayazi

All Dissertations

Summary: While traffic signals ensure safety of conflicting movements at intersections, they also cause much delay, wasted fuel, and tailpipe emissions. Frequent stops and goes induced by a series of traffic lights often frustrates passengers. However, the connectivity provided by connected vehicles applications can improve this situation. A uni-directional traffic signal to vehicle communication can be used to guide the connected vehicles to arrive at green which increases their energy efficiency; and in the first part of the dissertation, we propose a traffic signal phase and timing estimator as a complementary solution in situations where timing information is not available …

Electronic Deer Warning System, David Zhuo, Anlang Lu

Computer Engineering

Deer-vehicle collisions (DVCs) are extremely dangerous, often injuring or even killing drivers. Unfortunately, this form of automotive accident is commonplace in the United States. According to the NHTSA, DVCs result in 200 human deaths a year.2

Despite these deadly incidents, there currently are no deployed federal or state systems for preventing DVCs. There are many consumer electronic deer deterrent products, but their long-term effectiveness is questionable.3 In fact, there does not appear to be much research into electronic deer deterrent systems. Aside from constant audio output and electric shock, no other means of electronic deterrent exist. Even if fixed deterrents …

Active Contact Lens - Low Power Backscattering Sensor-To-Antenna Integration Circuitry, Caleb B. Porter

Electrical Engineering

The Active Contact Lens measures the cornea-scleral radius of the wearer’s eye, which correlates to intraocular pressure (IOP), Glaucoma’s primary indicator. IOP varies throughout the day, and is drastically different from person to person, so constantly measuring it over a period of a few days can provide individualized tracking of the disease’s development and will help doctors develop personalized treatment schedules to treat the disease more precisely.

The Active Contact Lens sensor measures strain, based on the cornea-scleral radius, and reports the results wirelessly, to allow monitoring of an individual’s IOP over time. The lens is powered similarly to a …

A Phenomenological Study Of Practicing Educators’ Personal And Collaborative Experiences Within A Climate Of High Stakes Individual Accountability, Kathy L. Stewart

Dissertations

With the national focus in education turning to increasing student achievement and closing achievement gaps between demographic groups, federal and state policy has extended responsibility and high stakes accountability for student growth and achievement. Overall, student achievement status and elimination of achievement gaps between demographically defined sub-groups of students remain cornerstones of accountability under ESEA and now ESSA. Under the Obama Administration, however, accountability for academic growth was extended to individual classroom teachers and school and district-level administrators through federal policy provisions tying student growth to performance evaluation. As a result, many states, including Michigan, enacted legislation to mandate high …

Grasping At Origins: Shifting The Conversation In The Historical Study Of Human Rights, Christopher N.J. Roberts

Chicago Journal of International Law

In recent years, scholars from a range of disciplinary orientations have invested considerable time exploring a very basic question: Where did human rights come from? The answers have not been so basic. There exists an extraordinary range of conflicting historical accounts. The hotly debated question of the moment within this field of study centers on figuring out which version of the history is the correct one. However, given the dramatic distance between the historical accounts, it is very unlikely that the matter will be settled in the near future. This Article argues that it is time to shift the focal …

Ido1 Is An Integral Mediator Of Inflammatory Neovascularization., Arpita Mondal, Courtney Smith, James B. Duhadaway, Erika Sutanto-Ward, George C. Prendergast, Arturo Bravo-Nuevo, Alexander J. Muller

Kimmel Cancer Center Papers, Presentations, and Grand Rounds

The immune tolerogenic effects of IDO1 (indoleamine 2,3-dioxygenase 1) have been well documented and genetic studies in mice have clearly established the significance of IDO1 in tumor promotion. Dichotomously, the primary inducer of IDO1, the inflammatory cytokine IFNγ (interferon-γ), is a key mediator of immune-based tumor suppression. One means by which IFNγ can exert an anti-cancer effect is by decreasing tumor neovascularization. We speculated that IDO1 might contribute to cancer promotion by countering this anti-neovascular effect of IFNγ, possibly through IDO1-potentiated elevation of the pro-tumorigenic inflammatory cytokine IL6 (interleukin-6). In this study, we investigated how genetic loss of IDO1 affects …

Nesting Behavior Of Acapulco Damselfish (Stegastes Acapulcoensis): Pairs Defend Nests More Vigorously Than Solitary Males, December 2016, Lauren Cech

Monteverde Institute: Tropical Ecology and Conservation

Unique pair behavior was observed in Stegastes acapulcoensis, the Acapulco damselfish, in the reefs of Santa Elena Bay of Costa Rica. Observations and video were collected on aggression and territoriality demonstrated by both male-female pairs and solitary males guarding eggs. Agonistic chases and chase distance were recorded over four days during snorkeling expeditions. Results compared parental care behavior (pairs versus solitary) with aggressive chases and chase distance. Solitary male Acapulco damselfish chase significantly less times than paired. Additionally, the paired males chase significantly farther than solitary. Males were observed to defend territory and eggs using aggressive chases, while paired females …

Presence Of Bacterial Microbiome And Incidence Of Infection In Chagas Disease Vectors Triatoma Dimidiata, December 2016, Amber Domako

Monteverde Institute: Tropical Ecology and Conservation

Chagas disease is a condition caused by the parasite Trypanosoma cruzi. In Costa Rica, it is spread by one species of kissing bug, Triatoma dimidiata. Recent studies have concluded that the microbiomes of insect disease vectors play a role in the insects’ transmission of diseases. My study examines the relationship between the number of individual bacteria morphospecies found in the microbiome of each T. dimidiata and whether that insect was a Chagas disease carrier. With this data, I analyzed the correlation between the presence of the trypanosome, or not, and the microbiome of the insect. I collected Chagas bugs from …

Volatile Compounds And Microbiota: Antibacterial Properties In Traditional Preparation Methods Of Medicinal Herb Neurolaena Lobata (Asteraceae), December 2016, Nina Djukic

Monteverde Institute: Tropical Ecology and Conservation

I assessed the differential effectiveness of traditional herbal preparation methods of medicinal herb gavilana (Neurolaena lobata) on an assay of four bacteria (E. coli, S. aureus, Shigella sp. and Salmonella sp.) known to cause food poisoning symptoms in humans. Medicinal plants are used both traditionally at home in many cultures and in the synthesis of pharmaceuticals. Their medicinal properties often come from their secondary compounds, chemicals that play a role in their ecophysiology and primarily defend them from herbivory. I prepared three types of Neurolaena lobata extracts - an oil, an alcohol, and a tea - and assessed the zones …

Ectoparasite Abundance And Diversity On Farm Animals In Monteverde And San Luis Along An Elevation Gradient, December 2016, Sarah Callahan

Monteverde Institute: Tropical Ecology and Conservation

Abundance and diversity of arthropods are largely dependent on climate. Elevation gradients provide different microclimates that can support a unique number and variety of species. In order to test the effect of elevation on abundance and diversity of arthropod ectoparasites, I collected samples on four different farms: Life Monteverde and Benito Guindon’s farm in Monteverde at about 1,800 m, and Lelo Mata’s farm and Tim Sayles’ farm in San Luis around 700 m. At each elevation, I compared abundance and diversity of ectoparasites on dogs and cattle. I found a presence of Ctenocephalides and Pulex fleas on dogs, and 22 …

How Water Quality Changes As It Passes Through Life Monteverde, December 2016, Stephanie Vogt

Monteverde Institute: Tropical Ecology and Conservation

Life Monteverde is a 17 hectare coffee farm in Monteverde, Costa Rica. To irrigate their garden and to provide water for their small amount of livestock, they divert water from a nearby stream that begins at a spring about a kilometer uphill from the farm. The farm has a system to filter the water it uses from the stream before returning it to the watershed in an effort to return it in better quality than when the water was diverted. I studied the use of this water over seven study sites as it flowed through the farm. Twice a day …

How Do Ithomiinae (Lepidoptera, Nymphalidae) Determine Which Flowers To Feed From?, December 2016, Jessie James

Monteverde Institute: Tropical Ecology and Conservation

Glasswing butterflies, of the subfamily Ithomiinae, feed almost exclusively from plants that produce pyrrolizidine alkaloids as secondary metabolites. They are able to extract the alkaloids from the nectar and use them as pheromones, as well as for chemical defense. The most common of these alkaloid-producing plants in the Monteverde zone is Santa Lucia, an Asteraceae. In order to determine what attracts Ithomiinae to these flowers, I presented them with three types of Santa Lucia flowers: unmodified flowers, dried flowers, and red-colored flowers. If the butterflies respond to visual cues, I predicted that they would visit the unmodified and dried flowers …

Coupled Fluid-Structure Interaction Modeling Of A Parafoil, Brandon Burnett

Doctoral Dissertations and Master's Theses

In the summer of 2014, Performance Designs, Inc. contacted Embry-Riddle Aeronautical University’s Eagle Flight Research Center to lead an investigation on square parachute design and optimization using modern computational methods to reduce costs in experimental testing. This thesis investigates the foundation for using an implicit fluid-structure interaction computational model to tackle the challenges of modeling a highly-flexible, porous fabric for design optimization of a parafoil parachute’s transient performance. Canopy deformations of a single-cell square parafoil using a fluid-structure interaction (FSI) model with nonlinear material modeling is compared to an experimental setup of matching geometry. The results of this thesis yielded …

Laboratory Development Of A Self-Powered Fontan For Treatment Of Congenital Heart Disease, Arka Das

Doctoral Dissertations and Master's Theses

Around 8% of all newborns with a Congenital Heart Defect (CHD) have only a single functioning ventricle. The Fontan operation has served as a palliation for this anomaly for decades, but the surgery entails multiple complications and survival rate is less than 50% by adulthood. A rapidly testable novel alternative is proposed by creating a bifurcating graft, or Injection Jet Shunt (IJS), used to “entrain” the pulmonary flow and thus provide assistance while reducing the caval pressure. A benchtop Mock Flow Loop (MFL) is configured to validate this hypothesis. The MFL is based on a Lumped-Parameter Model (LPM) of the …

Application Of Floating Pedal Regenerative Braking For A Rear-Wheel-Drive Parallel-Series Plug-In Hybrid Electric Vehicle With An Automatic Transmission, Dylan Lewis Lewton

Doctoral Dissertations and Master's Theses

As the world continues to move further away from our reliance on fossil fuels, hybrid vehicles are becoming ever more popular. Braking is a system on both hybrid and normal vehicles that involves a significant amount of power and energy. A hybrid can recapture some of that energy using regenerative braking. In this thesis, a method is devised to blend hydraulic and regenerative braking in the most effective manner. A MATLAB Simulink model was built to simulate a parallel-series plug-in hybrid electric vehicle. The model allows for the implementation of a regenerative brake controller that utilizes floating pedal regen, custom …

Homeland, Homestead, And Haven: The Changing Perspectives Of Zion National Park, 1700-1930, Sara Black

UNLV Theses, Dissertations, Professional Papers, and Capstones

Zion National Park is a landscape that the American public celebrates as a unique and beautiful wilderness. However, Zion is much more culturally layered than what most tourists perceive. Numerous Native American cultures have ties to the canyon, including the Southern Paiutes, who used and interacted with this area on a regular basis for at least the last 500 years. For them, it served both substantive and cultural roles in their communities that reinforced their understandings of themselves and their place in the world. For Mormons, who came into the area in the 1860s and quickly dominated the landscape, Zion …

Estimation And Comparison Of Thermoelectric And Pv Solar Water Usage In The Colorado River Basin States, Yuzhen Feng

UNLV Theses, Dissertations, Professional Papers, and Capstones

With the continual expansion of populations in the arid Southwest, energy demands will continue to rise. On the other hand, depleting water levels in reservoirs of the Colorado River Basin is expected to continue as more intense and frequent drought events persist in addition to the rapid development in the region. Currently, the three largest water-use categories in the United States are thermoelectric energy, irrigation, and municipal water, which cumulatively account for 90 percent of the national water use. In the Southwest, most of the total electricity generated is still through thermoelectric means. That is, massive amounts of water are …

Development Of The K-State (Competence) And Mutagenesis In Stressed Bacillus Subtillis Cells, Amanda Kidman

UNLV Theses, Dissertations, Professional Papers, and Capstones

Mutagenesis is central to the evolutionary process. We currently view evolution as a gradual process affecting all cells within a population. However, my project studied an underestimated part of the evolutionary process: mutations generated during stationary phase (caused by nutritional stress or growth arrest) within a subpopulation of cells. I used Bacillus subtilis, a bacterial model for cell growth and differentiation. Stationary-phase cultures of B. subtilis differentiate subpopulations that exhibit different survival strategies including competence, secondary metabolite production, biofilm formation, cannibalism, and endospore formation. The development of competence permits cells to uptake exogenous DNA and incorporate it into their genome. …

The goal of this research is to document and explore the changes and developments in food-related technology over time and to investigate possible factors that influenced its development.

To document this technology over the course of approximately 1000 years, four case study sites were used: The …

From Access To Excess: Agribusiness, Federal Water Programs, And The Historical Roots Of The California Water Crisis, Tracy Marie Neblina

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this paper is to show the link between water use, land consolidation, agribusinesses, and the water crisis that California began to experience in 2011. In order to better understand the relationship between the growth of agribusiness in the state and the evolution of water policy, this paper explores the historical context of land policy, the growth of farming in the San Joaquin Valley, and the development of federally funded water projects in the Central Valley. Years of expanding farmland and use of surface and underground water with limited regulation played an important role in exacerbating California’s water …

Interference Effects Of Urban Rubble On The Radioanalytical Analysis Of Strontium, Derek Roger Mclain

UNLV Theses, Dissertations, Professional Papers, and Capstones

Most current radioanalytical protocols have been developed for the analysis of air, water, soil and bioassay samples. While these protocols build the foundation of operational environmental monitoring, they are not necessarily suitable for the analysis of samples that will be encountered in the aftermath of a nuclear incident. In such a situation, it will be important to characterize the isotopes of interest present in the affected area to obtain signatures for nuclear forensics and ensure the appropriate response. Specifically, this research is aimed at the determination of strontium-90 and its separation from zirconium-90 in a post-detonation situation.

Strontium-90’s relatively long …
