Robust Nonparametric Quantification Of Clustering Density Of Molecules In Single-Molecule Localization Microscopy, Shenghang Jiang, Seongjin Park, Sai Divya Challapalli, Jingyi Fei, Yong Wang

Physics Faculty Publications and Presentations

We report a robust nonparametric descriptor, J'(r), for quantifying the density of clustering molecules in single-molecule localization microscopy. J'(r), based on nearest neighbor distribution functions, does not require any parameter as an input for analyzing point patterns. We show that J'(r) displays a valley shape in the presence of clusters of molecules, and the characteristics of the valley reliably report the clustering features in the data. Most importantly, the position of the J'(r) valley ([Formula: see text]) depends exclusively on the density of clustering molecules (ρc). Therefore, it is ideal for direct estimation of the clustering density of molecules in …

Sustainability Assessment Of U.S. Beef Production Systems, Greg Thoma, Ben Putman, Marty Matlock, Jennie Popp, Leah English

Food Systems

With increasing public concern and awareness of agricultural sustainability issues, comprehensive methodologies such as life cycle assessment are required to benchmark the beef industry and identify areas of opportunity for continuous improvement. To that end, the Beef Checkoff completed a retrospective sustainability assessment benchmark in 2013 by using Eco-efficiency analysis to compare the years 2005 and 2011. At the time of the analysis, the methodology used was the most up-to-date and comprehensive – indeed the analysis remains one of the only complete cradle-to-grave assessments of the U.S. beef industry. In 2015, a further refined version of the Eco-efficiency analysis was …

Cost Benefit Analysis Of Genetic Markers In Cattle, Josh Crystal

Agricultural Economics and Agribusiness Undergraduate Honors Theses

Genetic sequencing in beef cattle (L. Bos Taurus) is expected to aid producers select cattle with traits that enhance profitability. Using data from experimental trials conducted with Angus, Brahman, and their reciprocal cross, this project analyzes the profitability of grazing endophyte infected tall Fescue (L. Festuca arundinacea Schreb.) vs. Bermuda grass (L. Cynodon dactylon) pasture. The study is unique in the sense that actual cow-calf breeding failure rates (open cows were not culled) were tracked from 1991 to 1997 on herds that were bred to calf in spring and either exposed to fungal endophyte (L.Acremonium coenophialum Morgan-Jones …

Off The Grid, Matthew Owen Buffington

Graduate Theses and Dissertations

Off the Grid explores the messy relationship between public and private perceptions of our urban spaces, especially the tensions created when lived experience runs up against the physical and conceptual networks of cities: street grids, construction tape, and property lines. Incorporating different modes of spatial representation, from cartographic diagrams to isometric illustrations and Renaissance perspectives, this exhibition examines the role drawing plays in how we conceptualize the divisions and definitions of everyday space. The drawings engage the often overlooked detritus of city life, from layers of old graffiti to overgrown dirt piles and unmoored electrical wiring, that complicate our understanding …

Rock Art Management And Landscape Change: Mixed Field Assessment Techniques For Cultural Stone Decay, Kaelin M. Groom

Graduate Theses and Dissertations

As tourism continues to grow as one of the world’s most ubiquitous markets, the development and promotion of non-invasive techniques for cultural stone decay analysis and landscape change are vital to establishing conditional base-lines to best aid cultural heritage management (CRM) efficacy. Using rock art as a medium, this dissertation presents three independent case studies employing the Rock Art Stability Index (RASI) and repeat photography to explore the merits of mixed rapid field assessment techniques in relation to CRM and heritage tourism. While rock art is only one example of irreplaceable world heritage resources, examining how they decay and what …

Muscle Oxidative Phenotype In The Progression Of Cancer-Cachexia, Haley N. Mccarver

Health, Human Performance and Recreation Undergraduate Honors Theses

Cancer is one of the leading causes of death across the world. Cancer-cachexia is a serious complication induced by cancer resulting in whole body muscle wasting and is responsible for up to 40% of cancer related deaths. Underlying mechanisms of cancer-cachexia are not well understood; however, a loss in oxidative metabolism in skeletal muscle is apparent in cancer-cachexia. PURPOSE: To examine oxidative phenotype of skeletal muscle in tumor bearing mice during progression of cancer-cachexia. METHODS: Mice were implanted with Lewis Lung Carcinoma (LLC) or sham phosphate buffered saline (PBS) at 8 weeks of age. The tumor was allowed to progress …

Journal Of Food Law & Policy - Spring 2017, Journal Editors

Journal of Food Law & Policy

After Donald Trump’s victory last November, we put out a call for brief essays examining what happened, what’s likely to happen, and what policymakers and advocates can do to keep pushing forward. The response was extraordinary. We received thought provoking submissions on a number of important topics, including antitrust, trade policy, food safety, and labor, among others. Instead of running a standard issue comprised of legal articles—with essays as an accompaniment—we decided to reverse the format and devote the bulk of this issue to these essays. The result is a penetrating and timely look at the state of food law …

Implementing The National Bioengineered Food Disclosure Standard, Lesley K. Mcallister

Journal of Food Law & Policy

In July 2016, the National Bioengineered Food Disclosure Law was passed to establish a mandatory national system for disclosing the presence of genetically-engineered material in food (GMOs). The federal law preempts state and local initiatives to create labeling systems. This essay first analyzes the benefits and drawbacks of having a national GMO law rather than a patchwork of state laws. Then it provides commentary on how the USDA can create an effective and accessible labeling system, using scannable Quick Response (QR) codes.. The essay envisions a retail food system in which all consumers can easily and usefully obtain reliable information …

Aldf V. Otter: What Does It Mean For Other State’S “Ag-Gag” Laws?, Jacob Coleman

Journal of Food Law & Policy

Across the nation, states have enacted “Ag-gag” laws that criminalize various types of investigations into animal cruelty and worker abuses in the chain of animal agriculture. This article divides the types of “ag-gag” statutes into four waves with varying degrees of protection for farmers and corporations engaged in animal agriculture. Next, this article analyzes Animal Legal Defense Fund v. Otter, in which an Idaho judge struck down an “ag-gag” statute, and applies its holding to the various waves of “ag-gag” statutes.

The Delamination Of Manhattan: Living In The Layers Of A Post-Land Society, Dylan Hursley

Architecture Undergraduate Honors Theses

Rising water levels threaten the existence of many coastal cities throughout the world, including Lower Manhattan, which is in danger of sea level rise by as much as six feet by the end of the century! Higher sea levels mean that larger storms will occur with greater frequency. Assuming that humanity does not reverse its current ecological contribution, barriers to stop rising waters will not be adequate.

Manhattan is covered by 50 feet of water, transforming New York into a new Venice. The substantial bedrock of the city provides a hefty foundation capable of supporting Manhattan’s structures for many years …

Creating Better American Cities: A Study Of Circulation And Common Spaces Of Public Housing, Jessica Wood

Architecture Undergraduate Honors Theses

This thesis will analyze common spaces and circulation spaces in terms of configuration (in relation to each other) and quality (whether they are interior, exterior, or allow space for interaction between residents) in an attempt to determine how stairs, elevators, hallways, and common spaces impact the level of community within a public housing project. Community in this study refers to lasting relationships among residents living in the same housing project. The goal is to answer the question “What role do circulation and common spaces play in the success or failure of a public housing project?” and to determine the best …

Eulogy To Architecture: The Three-Dimensional Collage City Of Nostalgia, Molly A. Evans

Architecture Undergraduate Honors Theses

In our time of existence on the Earth, human beings have designed and realized beautiful things. As we face the challenges that confront us today, we begin to understand the fragility of humankind’s creations. Many of the world’s cities and buildings lie in ruins, gazed at by tourists, studied by scholars, while more lie buried in the ground for hundreds of years, some never to be rediscovered. Everything around us is an accumulation of knowledge and ideas built upon for centuries, now facing questionable circumstances. Of course, the more recent Aleppo and other Middle Eastern cities have fallen subject to …

The Effects Of Mesopredator Presence On Population Abundances Of Eastern Wild Turkey (Meleagris Gallopavo Silvestris), James Mcmichen

Biological Sciences Undergraduate Honors Theses

The eastern wild turkey (Meleagris gallopavo silvestris) has been an important game bird for the cultures and livelihood of peoples living in North America for centuries. Understanding how predation pressures affect wild turkey behavior can help us better manage turkey populations. I looked at three mesopredators: raccoons (Procyon lotor), gray foxes (Urocyon cinereoargenteus), and coyotes (Canis latrans) to see how they influence turkey presence at the White Rock Ecosystem Recreational Area, northwest Arkansas. I employed the use of 16 Moultrie trail cameras to ennumerate wild turkey and mesopredators at 29 sites. I deployed the cameras during late winter and early …

Will The Trump Administration Support Farmers Facing Fsma Compliance?, Sophia Kruszewski

Journal of Food Law & Policy

In keeping with Donald Trump’s campaign promises of cutting burdensome regulations, this essay recommends two Food Safety Modernization Act (FSMA) regulations that should be removed or altered. The two regulations are for irrigation water quality standards and third-party audits. This essay argues that these regulations are unnecessary in keeping with the goals of FSMA and are burdensome for farmers of all scales, but especially small and very small scale farmers.

Food Labor And The Trump Administration: A Grim Prognosis, Erik Loomis

Journal of Food Law & Policy

Farm laborers made few gains under the Obama administration; however, food workers received some benefit under the Obama’s Secretary of Labor, Tom Perez. Unfortunately, any gains for food workers will likely be rolled back under the Trump administration through both his cabinet appointments and judicial appointments. This essay predicts a strengthening of “ag-gag” bills and a weakening of Occupational Safety and Health Agency (OSHA). President Trump’s attacks on immigration and regulations also signal fewer workers’ rights in the fields and less accountability of exploitative employers.

Predicting The Onset Of Parturition By Determining Calcium In Prepartum Milk Of Sheep, Lensey Watson

Animal Science Undergraduate Honors Theses

Multiple methods of pregnancy detection can be used in sheep production. The gestation period for sheep is usually between 144 and 150 days; however, depending on the breed and age of the ewes, this number can vary. A breeding marker, such as a breeding crayon, is used to detect when the ewe is bred by the ram, and the date the ewe will lamb is typically calculated based on an average 145-day gestation. Unfortunately, this method provides only a rough estimate of when the ewe could lamb. In addition, because sheep routinely give birth to multiples (twins, triplets, and, sometimes, …

"A Magic Deeper Still": Sacramental Poetics In William Wordsworth, Christina Rossetti, And C.S. Lewis, Eric Michael Bontempo

Graduate Theses and Dissertations

A sacramental poetics requires a particular mode of being-in-the-world. Religiously-minded poets, from Dante and Milton to Donne and Herbert, have long considered how the individual becomes attuned with creation and God’s will. But what happens when modernity and secularization challenge long-held assumptions about the universe and how humankind fits into it? A reevaluation is then needed. My thesis begins with an examination of how William Wordsworth, who sort of falls into modernity, seeks to reoccupy the functions of religion in an increasingly secularized landscape. One consequence of the European Enlightenment is the disentangling and distancing that occurs in regards to …

Central Role Of Vasotocin In The Neuroendocrine Regulation Of Stress Responses And Food Intake In Chickens, Gallus Gallus, Gurueswar Nagarajan

Graduate Theses and Dissertations

It is well known that arginine vasotocin (AVT) in birds is involved in physiological homeostasis such as cardiovascular, osmotic regulation as well as reproductive functions. Pertinent to these physiological functions, AVT immunoreactive (-ir) neurons in the hypothalamus have been found associated with hemorrhage, dehydration, oviposition and other physiological regulation. Evidence, however, suggests that AVT also plays significant roles in modulating behavior, memory, stress, and food intake. This dissertation research addresses the latter two neuroendocrine functions of AVT in detail within the chicken brain. First, the functional role of AVT-ir neurons in conjunction with corticotropin releasing hormone (CRH)-ir neurons in the …

Identification Of Molecular Signatures Of Environmental And Nutritional Stress Responses In Poultry, Phuong Hieu Nguyen

Graduate Theses and Dissertations

Poultry production plays an important role in the food supply and security for billions of people. Poultry meat is considered the most efficient, nutritious source of protein, without religious taboos, and is relatively inexpensive. However, the poultry industry is facing substantial challenges. The global environmental temperature has experienced dramatic changes in the last few years. Modern broilers are not well adapted to environmental challenges (heat and cold stress), which have resulted in heavy economic loss in the poultry industry worldwide. In addition, the use of feed restriction regimens in management of breeders as well as the transportation of young chicks …

Influence Of Stream Permanence, Predation, And Invasive Species On Crayfish In The Ozark Highlands With An Emphasis On Species Of Greatest Conservation Need (Orconectes Marchandi, Orconectes Eupunctus And Cambarus Hubbsi), Allyson Noelle Yarra

Graduate Theses and Dissertations

Due to the ecological importance of crayfish and the increasing vulnerability of freshwater systems due to habitat loss, invasive species, and hydrologic alteration, understanding crayfish-environment relationships is crucial in the context of aquatic species conservation. I sought to examine the influence of hydrologic variation among intermittent and permanent streams on crayfish occupancy, abundance, predation risk, and potential vulnerability to invasive species effects. I conducted crayfish and environmental data sampling during two consecutive summers across 20 Ozark streams of differing permanence levels (10 intermittent, 10 permanent). In these same streams, I conducted fish and scat surveys over the course of four …

Flight Activity, Oviposition Pit Distribution, And Emergence Densities Of Monochamus Titillator And M. Carolinensis In The Ozark-St. Francis National Forest In Arkansas, Jake Bodart

Graduate Theses and Dissertations

Monochamus (Coleoptera: Cerambycidae) are a genus of longhorn beetles commonly known as pine sawyers. They have a worldwide distribution coincident with pines (Pinaceae) and are vectors of the pinewood nematode (Bursaphelenchus xylophilus). In the United States, there are eight known Monochamus species and they have a sympatric distribution with at least one other Monochamus species throughout their range. Monochamus are known to attack stressed, dead, and dying conifers especially pines. In the Ozark- St. Francis National Forest in Arkansas, there are two species of pine sawyers and they share this sympatric distribution observed throughout the United States, M. titillator (southern …

Cultural Reimagining And Literary Voice: Southeastern Tribal Women Negotiate Cultural, Social, And Political Identity Through Literature, Linda Sue Shaffer

Graduate Theses and Dissertations

This dissertation examines literature written by women who identify with Native tribes that originally inhabited, and in some cases continue to inhabit, the southeastern area of what is now known as the United States. The analysis presented in each chapter applies tribally specific methods used for creating knowledge within the particular discourse community being represented through literature. The project also employs the perspectives of Native literary scholars to consider the ways in which the roles and lives of Native women have been influenced by Euro-American values and to analyze the ways in which these female authors engage literature as a …

Phenology, Habitat Use, And The Impacts Of Wetland Management On Autumn Migrating Rails In Missouri, Auriel M.V. Fournier

Graduate Theses and Dissertations

Rails (Family: Rallidae) are among the least studied birds in North America, in large part due to their elusive nature. As a wetland-dependent species, understanding the timing of their migration and their habitat needs during migration is especially important since management needs to be timed to balance the needs of many species. I developed and verified a new distance sampling based nocturnal ATV spotlight survey because traditional call-broadcast surveys are not effective during autumn migration because of the drop off in call rate after the breeding season. These surveys allow us to ask point-level questions about what habitats rails select …

The Use Of Probiotics To Control The Microbial Load Present In Commercial Broiler Chicken Hatch Cabinets As An Alternative To Formaldehyde Fumigation, Lucas Elzie Graham

Graduate Theses and Dissertations

Formaldehyde has been used for decades as a disinfectant in the poultry hatchery. Hatch cabinets are treated with formaldehyde to control the microbial bloom that occurs inside of the hatch cabinet as the hatch progresses. Even with formaldehyde being a known human carcinogen and the detriment that it has on living creatures millions of chicks are exposed to formaldehyde in the hatch cabinet. In these experiments we tested a lyophilized probiotic spray inside of the hatch cabinets from day nineteen to day twenty one to control the microbial bloom that occurs. Hatch cabinet environments were sampled in six experiments. Media …

In Ovo Evaluation Of Floramax-B11 On Marek's Disease Hvt Vaccine Protective Efficacy, Hatchability, Microbiota Composition, Morphometric Analysis, And Salmonella Enteritidis Infection In Broiler Chickens, Kyle Dean Teague

Graduate Theses and Dissertations

It has previously been shown that effective probiotics can accelerate gut maturation and the development of a normal microflora in poultry. This results in increased resistance to enteric pathogens encountered by chicks early in life. Our objective in experiments 1 and 2 was to evaluate the effect of in ovo administration of FloraMax®-B11 (FM) on Marek’s disease (MD) herpesvirus of turkeys (HVT) vaccine protective efficacy. In Exp. 1, day 18 White Leghorn embryos were randomly distributed in four groups, 1) HVT vaccinated, no MDV challenge, 2) HVT + FM vaccinated, no MDV challenge, 3) HVT vaccinated, challenge with virulent MDV, …

Wayward Women, Macho Men: Linguistic Construction Of Gender Binaries In Yxta Maya Murray's Locas And Denise Chavez's Loving Pedro Infante, Stephanie Tangman

Graduate Theses and Dissertations

Language labels and defines in order to enhance meaning and communication, but through these labels and definitions speakers are also conditioned to associate certain connotations with words and, therefore, their referents. While often harmless, linguistic conditioning can at times create unsavory associations with these referents. One of these instances occurs in gendered labels and conceptions of male and female bodies and purpose. Both Yxta Maya Murray’s Locas and Denise Chavez’s Loving Pedro Infante can be read through a lens that applies linguistic conditioning with gender theory in order to examine the reinterpretation of female archetypes in the Chicana imagination. It …
