A Multicultural Nutrition And Culinary Intervention For Middle School Students: Pink And Dude Chefs, Phase 2, Jaime Lynn Lockhart
A Multicultural Nutrition And Culinary Intervention For Middle School Students: Pink And Dude Chefs, Phase 2, Jaime Lynn Lockhart
Master's Theses
The prevalence of adolescent obesity in the United States has more than quadrupled in the past 30 years, growing from 5% to nearly 21% in 12-19 year olds. Although obesity has many interrelated causes, a lack of knowledge and practical skill to prepare healthy food from scratch is an important factor. Research indicates that nutrition and culinary interventions based on behavioral change theories may improve mediators of healthful eating in adolescents.
Pink and Dude Chefs, Phase 2, an eight-week after-school nutrition and culinary intervention targeted towards middle school students in a predominantly low-income, Hispanic community, was developed and evaluated. The …

Investigating Hemodynamic Responses To Electrical Neurostimulation, Sean Youra
Master's Theses
Since the 1900s, the number of deaths attributable to cardiovascular disease has steadily risen. With the advent of antihypertensive drugs and non-invasive surgical procedures, such as intravascular stenting, these numbers have begun to level off. Despite this trend, the number of patients diagnosed with some form of cardiovascular disease has only increased. By 2030, prevalence of coronary heart disease is expected to increase approximately by 18% in the United States. By 2050, prevalence of peripheral arterial occlusive disease is expected to increase approximately by 98% in the U.S. No single drug or surgical intervention offers a complete solution to these …

Characterizing Populations Of Non-Coding Rnas In Karenia Brevis At Different Times Of The Diel Cycle, Scott Boyd Anglin
Characterizing Populations Of Non-Coding Rnas In Karenia Brevis At Different Times Of The Diel Cycle, Scott Boyd Anglin
Master's Theses
Karenia brevis is a mixotrophic, marine dinoflagellate found in the Gulf of Mexico that generates periodic, if not annual, harmful algal blooms (also known as “red tides”) in certain coastal areas. In an effort to better understand the biology of this organism, a functional genomics project has been initiated. As part of that project, it has been determined that a significant number of natural antisense transcripts (NATs) as well as double-stranded RNA (dsRNA) molecules exist within the transcriptome of K. brevis. I hypothesize that the non-coding NATs, similar to microRNAs (miRNAs) in other organisms play a role in regulating …
Selling Tradition: Impression Management And Draft Animal Agriculture Of A Mississippi Farmstead, Matthew Corbin Lance
Selling Tradition: Impression Management And Draft Animal Agriculture Of A Mississippi Farmstead, Matthew Corbin Lance
Master's Theses
This thesis is a case study of a family of farmers in Mississippi’s Piney Woods who use horse-drawn equipment to grow crops. This practice is notable in the context of a larger agricultural system that prioritizes mechanization (particularly the use of tractors). The production style and their use of local direct selling via farmers markets allowed them to thrive economically because they were able to tap into a niche market of consumers desiring an alternative to the modern, conventional agricultural system.
Other literature on Alternative Food Networks (AFN) discusses the issues of alterity and appropriation—that is, whether AFN ventures are …

Role Of Msaa Gene In Regulation Of The Msaabcr Operon And Biofilm Development In Staphylococcus Aureus, Ahmed Alzuway
Master's Theses
Staphylococcus aureus is an important human pathogen that causes wide variety of diseases ranging from chronic biofilm associated infection to acute life threatening infection such as bacteremia, pneumonia, osteomyelitis, or endocarditis, despite the progress with antibiotics used in the treatment of bacterial infections. Furthermore, increased use of prosthetic and indwelling devices in modern medical practices has led to increased infections due to S. aureus. Treating S. aureus infections have become difficult owing to its ability to resist most of the antibiotics; this problem is further exacerbated by ability of MRSA strains to form biofilms. Emergence of community-acquired methicillin resistance …

Decafs: A Modular Distributed File System To Facilitate Distributed Systems Education, Halli Elaine Meth
Decafs: A Modular Distributed File System To Facilitate Distributed Systems Education, Halli Elaine Meth
Master's Theses
Data quantity, speed requirements, reliability constraints, and other factors encourage industry developers to build distributed systems and use distributed services. Software engineers are therefore exposed to distributed systems and services daily in the workplace. However, distributed computing is hard to teach in Computer Science courses due to the complexity distribution brings to all problem spaces. This presents a gap in education where students may not fully understand the challenges introduced with distributed systems. Teaching students distributed concepts would help better prepare them for industry development work.

Sensitivity Of Stormwater Management Solutions To Spatial Scale, Jeffrey Michael Barich
Sensitivity Of Stormwater Management Solutions To Spatial Scale, Jeffrey Michael Barich
Master's Theses
Urbanization has considerably altered natural hydrology of urban watersheds by increasing runoff volume, producing higher and faster peak flows, and reducing water quality. Efforts to minimize or avoid these impacts, for example by implementing low impact development (LID) practices, are gaining momentum. Designing effective and economical stormwater management practices at a watershed scale is challenging; LIDs are commonly designed at site scales, considering local hydrologic conditions (i.e., one LID at a time). A number of empirical studies have documented hydrologic and water quality improvements achieved by LIDs. However, watershed scale effectiveness of LIDs has not been well studied. Considering cost, …

Tspoons: Tracking Salience Profiles Of Online News Stories, Kimberly Laurel Paterson
Tspoons: Tracking Salience Profiles Of Online News Stories, Kimberly Laurel Paterson
Master's Theses
News space is a relatively nebulous term that describes the general discourse concerning events that affect the populace. Past research has focused on qualitatively analyzing news space in an attempt to answer big questions about how the populace relates to the news and how they respond to it. We want to ask when do stories begin? What stories stand out among the noise? In order to answer the big questions about news space, we need to track the course of individual stories in the news. By analyzing the specific articles that comprise stories, we can synthesize the information gained from …

Laser Speckle Imaging: A Quantitative Tool For Flow Analysis, Taylor A. Hinsdale
Laser Speckle Imaging: A Quantitative Tool For Flow Analysis, Taylor A. Hinsdale
Master's Theses
Laser speckle imaging, often referred to as laser speckle contrast analysis (LASCA), has been sought after as a quasi-real-time, full-field, flow visualization method. It has been proven to be a valid and reliable qualitative method, but there has yet to be any definitive consensus on its ability to be used as a quantitative tool. The biggest impediment to the process of quantifying speckle measurements is the introduction of additional non dynamic speckle patterns from the surroundings. The dynamic speckle pattern under investigation is often obscured by noise caused by background static speckle patterns. One proposed solution to this problem is …

We have used and outlined the merits of a number of existing testing tools
and brought together the best among them to create what we believe is a fully- featured, easy to use, testing framework and workflow for web application …
Predicting Music Genre Preferences Based On Online Comments, Andrew J. Sinclair
Predicting Music Genre Preferences Based On Online Comments, Andrew J. Sinclair
Master's Theses
Communication Accommodation Theory (CAT) states that individuals adapt to each other’s communicative behaviors. This adaptation is called “convergence.” In this work we explore the convergence of writing styles of users of the online music distribution plat- form SoundCloud.com. In order to evaluate our system we created a corpus of over 38,000 comments retrieved from SoundCloud in April 2014. The corpus represents comments from 8 distinct musical genres: Classical, Electronic, Hip Hop, Jazz, Country, Metal, Folk, and World. Our corpus contains: short comments, frequent misspellings, little sentence struc- ture, hashtags, emoticons, and URLs. We adapt techniques used by researchers analyzing other …
A Proof Of Concept For Crowdsourcing Color Perception Experiments, Ryan Nathaniel Mcleod
A Proof Of Concept For Crowdsourcing Color Perception Experiments, Ryan Nathaniel Mcleod
Master's Theses
Accurately quantifying the human perception of color is an unsolved prob- lem. There are dozens of numerical systems for quantifying colors and how we as humans perceive them, but as a whole, they are far from perfect. The ability to accurately measure color for reproduction and verification is critical to indus- tries that work with textiles, paints, food and beverages, displays, and media compression algorithms. Because the science of color deals with the body, mind, and the subjective study of perception, building models of color requires largely empirical data over pure analytical science. Much of this data is extremely dated, …

Studies And Research Regarding Sound Reduction Materials With The Purpose Of Reducing Sound Pollution, Timothy G. Hawkins
Master's Theses
Noise can be defined as unwanted sound. There are many cases and applications that reducing noise level is of great importance. Loss of hearing is only one of the effects of continuous exposure to excessive noise levels. Noise can interfere with sleep and speech, and cause discomfort and other non-auditory effects. High level noise and vibration lead to structural failures as well as reduction in life span. The importance of noise issue could be well understood by looking at regulations that have been passed by governments to restrict noise production in society. Industrial machinery, air/surface transportation and construction activities are …

The Role Of Sirtuin Inhibitors On The Proteomic Responses Of The Mussels Mytilus Galloprovincialis And Mytilus Trossulus To Menadione Induced Oxidative Stress, Hayley C. Chilton
The Role Of Sirtuin Inhibitors On The Proteomic Responses Of The Mussels Mytilus Galloprovincialis And Mytilus Trossulus To Menadione Induced Oxidative Stress, Hayley C. Chilton
Master's Theses
Global climate change imposes physiological constraints on marine ecosystems that can alter the distribution of intertidal organisms. In one such instance, the native cold-adapted mussel Mytilus trossulus is being replaced along its southern range by the invasive warm-adapted Mytilus galloprovincialis. These blue mussels occur throughout rocky intertidal zones where they are subjected to greatly varying environmental conditions known to induce oxidative stress. We hypothesize that while under acute stress, related Mytilus congeners undergo a shift in redox potential from NADH-fueled respiratory pathways to pathways producing NADPH as a way to decrease the production of reactive oxygen species (ROS) and …

Public Art: Context & Process In San Luis Obispo, Ca, Kristin Ann Kiefer
Master's Theses
Public spaces are noted by historians, philosophers, planners, etc as being the lifeblood of civic centers, spaces that bring people in community together for a myriad of reasons. Recalling the ancient Agricola’s of ancient Greece to the modern version of malls and pedestrian plazas, these spaces are where social interactions occur, ideas are spread, and are open for all people to enjoy. Beautifying these spaces with public art and well-thought out design encourage the use of these spaces and work to empower those who use them. While the mode in which public art populates public spaces has changed, the notion …
