Fueling Ukraine’S Future: Using Microfinance As A Tool For Reducing Energy Dependency And Changing Lives, Justin Cole

Renée Crown University Honors Thesis Projects - All

Ukraine is a country heavily dependent on other countries for its natural gas supply, leaving it vulnerable to interruptions in supply. One of its largest suppliers, Russia, has twice taken drastic means of physically closing the pipelines, thereby cutting off this supply and illustrating to Ukraine and the world the leverage that it can exercise. While at the present time the cut-offs have lasted no longer than a few weeks, future cut-offs could become more common and longer in duration. When compounded with the troubled history between the two countries, one can quickly see the precipitous situation that has the …

High School Students’ Knowledge Of Careers And Non-College Post-Secondary Options, Mariel Stein

Renée Crown University Honors Thesis Projects - All

This Capstone Project discusses high school students’ knowledge of careers and non-college post-secondary options. The problem this project addresses is the fact that many high school students lack adequate knowledge of careers and non-college post-secondary options, and therefore they often make poor decisions regarding their post-secondary plans.

The methodology used was research, observations, and personal communication. I conducted inductive research because I felt that my information of high school vocational education was too narrow and I wanted to broaden my knowledge to see what the trend is across the country, what the causes of the aforementioned problem are, and what …

Sovereign Wealth Funds: Global And Domestic Implications Of The Rise Of A New Major Player In International Finance, Michelle Sollod

Renée Crown University Honors Thesis Projects - All

The subject of petrodollar recycling has frequently captured the interest of academics, politicians and the media. Specifically, the issue typically boils down to one central question: where exactly are the petrodollars—revenue earned from the sale of oil—flowing? According to traditional scholars like Bernard Mommer and Terry Lynn Karl the recurring argument is that in oil-exporting nations, oil revenues are channeled directly into the hands of a few government officials resulting in corruption, inequality and economic decay.

However, the main limitation of this traditional argument is that it tends to focus solely on the dynamics between the national level and local …

Liminality As A Space Of Self Reflection On El Camino De Santiago Del Norte, Amanda Redpath

Renée Crown University Honors Thesis Projects - All

As ancient pilgrimage across Spain, El Camino de Santiago has affected the lives of the pilgrims that travel it for centuries taking on new meanings as it passes through time. Traditionally, scholars maintain that the focus of a pilgrim’s journey lies at the final destination, or pilgrimage center in Santiago de Compostela. This project demonstrates, however, that the emphasis should lie on the journey or period of liminality which through concepts of place has created a space for self-reflection and meditation. Analysis of pilgrim interviews within the context of a wide array of scholarly literature in the disciplines of anthropology, …

Regulation Of Immediate Early And Epithelial–Mesenchymal Transition Genes Expression By Adipocytokines In The Female Reproductive Tract, Zhufeng Yang

Department of Animal Science: Dissertations, Theses, and Student Research

Individuals who are overweight or obese are at increased risk for cancer.  However, the mechanistic link between obesity and cancer is poorly defined.  Adipose tissue produces hormones and pro-inflammatory cytokines with mitogenic properties.  Many of these hormones and cytokines are altered in obese individuals and may lead to disruption of the normal balance between cell proliferation, differentiation, and apoptosis. Thus, the objective of this study was to determine how adipocyte-derived factors regulate the expression of genes that contribute to cell proliferation and migration.  To compare immediate early gene (cell proliferation) and epithelial-mesenchymal transition (cell migration) gene expression between untreated and …

Analysis Of Long-Term Selection (28 Generations) For Reproduction, Growth, And Carcass Traits In Swine, Wan-Ling Hsu

Variation In Response To Both Natural And Experimental Infection With Porcine Circovirus 2b, Theresa P. Bohnert

Department of Animal Science: Dissertations, Theses, and Student Research

In animals, disease progression can be influenced by genetics, environment, management practices, and the type of pathogen. Infection with porcine circovirus 2 (PCV2) causes development of diseases known as porcine circovirus 2-associated diseases (PCVAD), for which there is currently no treatment. In Trial 1, weanling unvaccinated barrows and gilts (n = 229) from two genetic lines were bled at d14, 49, and at necropsy to assess disease progression from natural infection using antibodies (ELISA) and viral copy counts (quantitative PCR). Virus was isolated from infected pigs and sequenced to determine the strain responsible for infection. At d49, 113 animals …

Evaluating The Impacts Of Production Process And Product Origin On Willingness To Pay For Shrimp, Addison Ellis

All Theses

The 2002 Farm Bill included a provision requiring various agricultural commodities to comply with country of origin labeling (COOL). Proponents of COOL argued that the policy would support U.S. producers and benefit U.S. consumers. This argument was based on the assumption that U.S. consumers prefer domestic products to imported products and hence the demand for U.S. products would increase following the implementation of COOL. However, analyzing the impact of COOL on shrimp, one of the first commodities covered the program, is complicated by recent trade disputes, concerns over the safety of farm raised products and potential stigma effects associated with …

Microbiological Safety Of Organic Fertilizers Used For Produce Production, Cortney Miller

All Theses

Over the last few decades there has been an increase in the use of organic fertilizers due to the rise in popularity of organic food production. However, if the fertilizers are not adequately sanitized there is the possibility of contamination of agricultural crops by foodborne pathogens from the spreading of organic fertilizers onto the crops. This is especially important for animal waste-based fertilizers since animals frequently carry foodborne pathogens. Furthermore, antibiotic use in food animal production may induce antimicrobial resistance in gut bacteria which can be spread to crops and the environment through fertilizer use. The objectives of this study …

Fate And Transport Of Escherichia Coli Within Sediment Basins On Active Construction Sites, Elizabeth Tempel

All Theses

The conventional method of controlling sediment-laden runoff on construction sites is the use of sediment basins. These basins slow the velocity of runoff and allow the particles to settle from the water column before discharge to surface waters offsite. This best management practice, however, may create a reservoir for pathogenic bacteria. Sediment is known to provide protection for bacteria; therefore, while these basins decrease sediment loadings to water bodies downstream, they may introduce harmful levels of pathogenic bacteria into these surface waters. In addition to causing human health risks, these high bacteria levels alter natural biological makeup of downstream ecosystems. …

Effects Of Microenvironment On Growth And Differentiation Of Human Dental Pulp Cells, Laura Datko

All Theses

Dental pulp stem cells (DPSCs) have recently been described as a potential stem cell source for various regenerative medicine and tissue engineering applications. They appear to be multipotent, however more characterization is necessary to determine the true potential of these cells. An important aspect of using DPSCs, or any stem cell type, tissue engineering application is the microenvironment within the construct. The microenvironment could include construct mechanical properties, construct composition, and 3D dynamic conditions in vivo. This work aims to study those specific microenvironment effects on DPSCs. To determine the effects of mechanical properties of the substrate on DPSCs, they …

The Impact Of Trade Costs In Indonesian Agri-Food Sectors: An Interregional Cge Analysis, Irlan Rum

All Theses

An interregional Computable General Equilibrium (CGE) approach is used to measure the impact of variable internal trade costs have on regional consumer welfare and interregional market integration within the Indonesian economy. Existing high interregional price differences in the agri-food markets suggest the presence of variable internal trade costs, which serve as effective barriers to interregional trade. Given the important role of agri-food markets in both food security and income generation for rural households, these price differences can have significant welfare impacts on both producers and consumers. Reducing the costs of trade between Indonesia's various regions could facilitate interregional trade. Trade …

Open Source Rigging In Blender: A Modular Approach, Ryan Cushman

All Theses

Character rigs control characters in the traditional CG pipeline. This thesis examines the rig creation process and discusses several problems inherant in the traditional workflow--excessive time spent and a lack of uniformity, and proposes a software plugin which solves these issues. This thesis describes the creation of a tool for Blender 3D which automates the rigging process yet keeps the creativity and control in the hands of the user. A character rig designed by this tool will be fully functional--yet capable of being split into its component parts and reconstructed as the user determines. These body parts are individually scripted …

Examination Of Qualitative Methodology Usefulness In Assessing Management Effectiveness Of Protected Areas: A Case Study Of Mexico, Carla Mora-Trejos

All Theses

Parks and Protected Areas (PAs) are an important approach for conservation of cultural and natural diversity worldwide (Bruner 2001; McNeely 1994; Rao & Geisler 1990). Their long term success depends on effective management in relation to the goals set forth for the PA. Measuring this can be complex and challenging and has been done in a variety of ways in order to better get at the answer of how to measure management effectiveness. The purpose of this research was to develop and test qualitative methodology designed to explore management effectiveness using all six elements from the WCPA framework (Hockings et …

The Ideology Of Equality: James Murray Mason And Antebellum Politics, Adam Zucconi

All Theses

Most studies of antebellum Virginia politician James Murray Mason examine his post-Senate career as Confederate ambassador to England. Those that do explore his tenure as a senator and, earlier, state politician, misinterpret his ideology and portray him as a proslavery demagogue. Perhaps most troubling, few delve into the political context of Virginia, and the forces and tensions present in the Commonwealth during this period. This study seeks to question this historiographical trend by asking a question basic to any understanding of Mason's career: What was the foundation of James M. Mason's political ideology, and how did he balance it as …

A Forgotten Typology: The Rediscovery Of The Train Stations On The Oldest Railroad In The Country, Lora Ann Cunningham

All Theses

The Charleston and Hamburg Railroad in South Carolina, when completed in 1833, was the first steam powered railroad in America. It was also the longest in the world at 136 miles. The railroad was initially referred to as the 'Best Friend of Charleston.' On December 25, 1830, the 'Best Friend' engine made its first public run on the freshly laid railroad tracks. This milestone trip shifted the country toward an era of transportation development. With this new form of transportation came a new building type, the train station. The train station was the first building to greet people when they …

Problem-Solving Courts And The Defense Function: The Wisconsin Experience, Ben Kempinent

UC Law Journal

Problem-solving courts have emerged as one of the fastest growing innovations in the criminal justice system. Their growth has not been without controversy, given their dramatic departure from a traditional adversary model in favor of a collaborative approach in dealing with offenders with serious alcohol or substance abuse, or mental health issues. The most outspoken criticism of this approach has come from the defense bar. This Essay suggests much of the criticism is misplaced, and, that if care is exercised in separating the roles that defense counsel plays in communities with problem-solving courts the promise of this approach for appropriate …

Statistical Comparisons Of Watershed-Scale Response To Climate Change In Selected Basins Across The United States, John Risley, Hamid Moradkhani, Lauren Hay, Steve Markstrom

Civil and Environmental Engineering Faculty Publications and Presentations

In an earlier global climate-change study, air temperature and precipitation data for the entire twenty-first century simulated from five general circulation models were used as input to precalibrated watershed models for 14 selected basins across the United States. Simulated daily streamflow and energy output from the watershed models were used to compute a range of statistics. With a side-by-side comparison of the statistical analyses for the 14 basins, regional climatic and hydrologic trends over the twenty-first century could be qualitatively identified. Low-flow statistics (95% exceedance, 7-day mean annual minimum, and summer mean monthly streamflow) decreased for almost all basins. Annual …

Salen Mn Complexes Mitigate Radiation Injury In Normal Tissues, Rosalind A. Rosenthal, Brian Fish, Richard P. Hill, Karl D. Huffman, Zelmira Lazarova, Javed Mahmood, Meetha Medhora, Robert C. Molthen, John E. Moulder, Stephen T. Sonis, Philip J. Tofilon, Susan R. Doctrow

Biomedical Engineering Faculty Research and Publications

Salen Mn complexes, including EUK-134, EUK-189 and a newer cyclized analog EUK-207, are synthetic SOD/catalase mimetics that have beneficial effects in many models of oxidative stress. As oxidative stress is implicated in some forms of delayed radiation injury, we are investigating whether these compounds can mitigate injury to normal tissues caused by ionizing radiation. This review describes some of this research, focusing on several tissues of therapeutic interest, namely kidney, lung, skin, and oral mucosa. These studies have demonstrated suppression of delayed radiation injury in animals treated with EUK-189 and/or EUK-207. While an antioxidant mechanism of action is postulated, it …

Mitigation Of Bovine Respiratory Disease Complex: Interactions Of Physiology, Immunology, Nutrition And Management, John Thomas Richeson

Graduate Theses and Dissertations

A series of experiments were conducted to determine the effects of on-arrival vs. delayed respiratory vaccination and exposure to persistently infected bovine viral diarrhea virus challenge on health, gain performance, and physiological and immunological measurements in newly received stocker cattle. Two experiments evaluated timing (d 0 vs. 14) of respiratory, clostridial, or both vaccinations in newly received stocker calves during stress-induced immunosuppression. In Exp. 1, calves receiving 14-d delayed vaccination of a pentavalent modified-live respiratory virus (MLV) vaccine had greater ADG during the 42-d receiving period and antibody titers against infectious bovine rhinotracheitis on d 42; however, morbidity rate did …

The strains were tested using a ninety-six well microtiter plate method, with or without membrane filtration. The compound 2, 3, 5-triphenyl tetrazolium chloride was used as a growth indicator. Serial, two fold dilutions …

An Empirical Investigation Of Emotional Reactivity And Elevated Mental Contamination: A Comparison Of Sexual And Physical Assault, Christal Badour

Graduate Theses and Dissertations

Although evidence suggests that disgust and disgust-related phenomena such as mental contamination should be associated with the experience of sexual assault, there has been relatively little direct examination of this relation. Consequently, the primary aim of the current study was to conduct a multimodal assessment of disgust and mental contamination-based reactivity to an individualized script-driven imagery procedure. Participants included 27 sexually assaulted, 25 physically assaulted, and 30 non-traumatized control female adults. Subjective reactivity (i.e., ratings of disgust, anxiety, feelings of dirtiness, and urges to wash), physiological reactivity (i.e., electromyogram activity of the right levator labii superioris and medial frontalis regions) …

Southern Exceptionalism And Its Impact On Environmental Attitude, Summer Dawn Woehr

Graduate Theses and Dissertations

In recent years, the environment has become a top concern for many people. Scientific studies have shown evidence of immediate and future threats on our environment. Despite the vast amount of evidence, many people (especially in the South) do not believe there is a human cause for global warming, a fundamental part of the environmental movement. Literature suggests Southern exceptionalism may a play a part in shaping attitudes toward environmental policies in the South. Further, a recent look at V.O. Key Jr.'s 1949 Southern Politics in State and Nation suggests that religion has since been overlooked as an explanation for …

The Effects Of Ovariecotomy On Neuropeptide Y Neurotransmission In Skeletal Muscle Arterioles, Kirk Wendell Evanson

Graduate Theses and Dissertations

The purpose of this study was to determine the effects of chronic estrogen supplementation on NPY neurotransmission in gastrocnemius first-order arterioles (G1A) of adult female rats. Female rats (4 mo; n = 30) were ovariectomized (OVX) with a subset (n = 15) receiving an estrogen pellet (OVE; 17β-estradiol (4μg / day)). Following conclusion of the treatment phase (8 weeks), red G1A were excised, placed in a physiological saline solution (PSS) bath, and cannulated with micropipettes connected to albumin reservoirs. A sampling port was placed immediately below the vessel to assess NPY overflow. The contralateral red G1A was homogenized in PSS …

The Role Of Albino3 And The Lipid Environment In Chloroplast Signal Recognition Particle Targeting, Nathan Lewis

Graduate Theses and Dissertations

Signal recognition particles (SRPs) in pro- and eukaryotes function in cotranslational targeting of nascent poplypeptides to an SRP receptor at the target membrane. A unique chloroplast SRP (cpSRP) functions post-translationally to direct light-harvesting chlorophyll-binding proteins (LHCPs) to the receptor cpFtsY at the thylakoid membrane for LHCP insertion in a process involving the integral membrane protein Albino3 (Alb3) and requiring GTP. Work here focuses on understanding cpSRP targeting events at the thylakoid membrane, specifically those involving Alb3 and the lipid environment.

We show an interaction between the novel cpSRP subunit cpSRP43 and the soluble, stromal-exposed C terminus of Albino3 (Alb3-Cterm). We …
