Theses and Dissertations--Animal and Food Sciences

The objective of this study was to evaluate the survival of non-O157:H7 STEC, Salmonella spp., and S. aureus in dry fermented sausages. Chorizo and Landjager sausages were inoculated with individual bacterial cocktails and stuffed into natural casings. Temperature, relative humidity, pH, and water activity were monitored through fermentation, drying, and storage. Bacterial counts were determined by serial dilution and plated in triplicates on selective media. Plates were incubated at 37°C for 24 hours and colony forming units per gram (CFU/g) were observed.

Results of the first study validate that contaminated raw materials contribute to pathogen survival and background bacteria outcompeted …

Effects Of Yeast-Derived Microbial Protein On Transition Dairy Cow Health And Performance, Gustavo Mazon Correa Alves

Theses and Dissertations--Animal and Food Sciences

The transition period for dairy cows is defined as the three weeks pre and postpartum. During the transition period, dairy cows experience a myriad of metabolic, managerial, and nutritional requirement changes. These changes lead to stress and increased susceptibility to diseases which can negatively affect lactational performance in the short and long term. However, dietary amino acid availability can have a dramatic impact on the health and performance of dairy cows around parturition. Thus, the objective of the thesis was to evaluate the effects of supplementing yeast-derived microbial protein, as an alternative protein source for dairy cows during the transition …

Theses and Dissertations--Animal and Food Sciences

Two experiments were used to evaluate the potential interaction of fat source and vitamin E (VE) in heavy slaughter weight pigs. In Experiment 1, a total of 64 individually-fed pigs (28.41 ± 0.83 kg) were randomly assigned to 8 dietary treatments in a 4×2 factorial arrangement. Fat treatments included cornstarch (CS), tallow (TW), corn-oil (CO), and coconut-oil (CN). VE treatments were dietary α-tocopheryl acetate (ATA) at 11 and 200 ppm. In Experiment 2, a total of 72 individually fed pigs (28.55 ± 1.16 kg) were randomly assigned to 12 dietary treatments in a 2 × 6 factorial arrangement. Fat treatments …

Metabolizable Energy Determination In Broiler Chickens, Andrew E. Dunaway

Theses and Dissertations--Animal and Food Sciences

Feed accounts for the highest cost associated in poultry production, with energy-containing feedstuffs being the most expensive portion of the cost of feeding. The increasing demand for poultry meat gives reason to determine accurate apparent metabolizable energy (AME) values for various feedstuff through measuring energy utilization in the birds. The adaptation length of birds fed an experimental diet may affect the determined AME value due to the diet matrix and physiochemical properties of the feedstuff. Therefore, the objective of this thesis was to evaluate a select group of energy-containing feedstuff with different diets and with factors such as coccidia challenge …

Thermal, Interfacial, And Application Properties Of Pea Protein Modified With High Intensity Ultrasound, Aeneas Koosis

Theses and Dissertations--Animal and Food Sciences

The overall objective of the study was to investigate different food ingredient conditions and ultrasound treatment on pea protein in terms of surface morphology and thermal characteristics. The motivation of this work was based on previous studies focusing on non-chemical physical modifications of plant proteins and the increasing demand for functional alternative proteins.

Ultrasonication time and amplitude, pH, protein concentration, and salt concentration all influenced the thermal and interfacial properties of pea protein. Ultrasound treatment altered the quaternary and tertiary structure of the storage protein and disrupted non-covalent bonds. The structural altercations and a reduction in particle size led to …

Evaluating Costs Associated With Management Decisions Of Replacement Dairy Heifers And Their Impact On The Total Rearing Investment, Anna Catherine Hawkins

Theses and Dissertations--Animal and Food Sciences

Replacement heifer rearing is critical for the future of the dairy operation, especially to improve genetic merit and maintain herd size. A replacement heifer from the day she is born to the day she calves herself is generally a 2-year investment without potential income. A myriad of options exists on how to manage, fed, and ultimately raise replacement heifers. This study quantifies the costs associated with replacement heifer management decisions from birth to calving related to housing, labor, feed and health. The heifer rearing period can be broken into pre and post weaning sections to allow for more understanding the …

Evaluation Of Current And Emerging Techniques For Measuring Eggshell Integrity Of The Domestic Fowl, Lauren Wood Nolan

Theses and Dissertations--Animal and Food Sciences

This dissertation is an investigation into the effect of different zinc sources and levels on eggshell quality and microstructure, as well as keel bone damage. Eggshell function is two-fold; eggshells function to protect the developing embryo, as well as act as a barrier against bacterial penetration, optimizing food safety of the egg for human consumption (Mabe et. Al., 2003). Two small trials were conducted in order to determine differences in eggshell microstructure of eggs produced from hens at peak lay (26 weeks of age) and at the end of lay (88 weeks of age). Two groups of hens were fed …

Anthropology Faculty Publications and Presentations

This is a chapter in Language and Toponymy in Alaska and Beyond: Papers in Honor of James Kari.

Book description:
It is difficult to imagine place names research in Alaska without the work of James Kari. Through his tireless field work and advocacy, Dr. Kari has collaborated with speakers of all of Alaska’s Dene languages to help build a comprehensive record of Dene geographic knowledge. When Jim came to Alaska in 1972, the documentation of Dene languages was fragmentary at best, and the only records of Native place names were those found inaccurately spelled on maps and gazetteers. Now …

How People With Multiple Sclerosis Experience Web-Based Instructional Technologies, Gary Eugene Deroest

Walden Dissertations and Doctoral Studies

People with the autoimmune disease multiple sclerosis (MS) have few options for

educational activities. Although web-based instruction may be a viable option, little is known about how people with MS perceive this form of learning. The purpose of this qualitative study was to understand the experiences of people with MS regarding web- based instruction. The 3 learning structures--differentiated instruction, collaborative learning, and assistive technology--provided the conceptual framework for this research. Nine volunteers from the Pacific Northwest area of the United States who have MS were individually interviewed for this basic qualitative study.

Zika And Flavivirus Shell Disorder: Virulence And Fetal Morbidity, Gerard Kian-Meng Goh, A. Keith Dunker, James A. Foster, Vladimir N. Uversky

Molecular Medicine Faculty Publications

Zika virus (ZIKV) was first discovered in 1947 in Africa. Since then, sporadic ZIKV infections of humans have been reported in Africa and Asia. For a long time, this virus was mostly unnoticed due to its mild symptoms and low fatality rates. However, during the 2015–2016 epidemic in Central and South America, when millions of people were infected, it was discovered that ZIKV causes microcephaly in the babies of mothers infected during pregnancy. An examination of the M and C proteins of the ZIKV shell using the disorder predictor PONDR VLXT revealed that the M protein contains relatively high disorder …

Bet You Can’T Eat Just One: Binge Eating Disorder Promotion In American Food Advertising, Debbie Danowski

Communication, Media & The Arts Faculty Publications

"Eat Like Andy“; "What Would You Do For A Klondike Bar?“ For well over a century, American food manufacturers have been competing for consumers’ attention through the use of catchy jingles, iconic characters and celebrities. At the same time, the products being advertised contain greater amounts of addictive ingredients, which encourage binge eating resulting in an unprecedented obesity epidemic. Combine this with the full-scale commercialization of the culture today“. Jhally identifies and the powerful impact of food advertisements becomes clear as does the need to evaluate these ads. As Kilbourne noted nearly a quarter of a century ago, the majority …

From The Dirt Up: Layering Story, Place, And Environmentalism Within Three Picture Books, Lucinda Rowe

Children's Book Writing and Illustrating (MFA) Theses

The world is changing before our eyes – species are going extinct, the amount of habitat available to wildlife has decreased, and children are spending less time outside than in the past. Through analyzing environmental ideology within early childhood education and children’s literature, I demonstrate that picture books can inspire nature conservation, appreciation, and stewardship by encouraging outdoor play and exploration. I compare picture books that successfully demonstrate eco-consciousness without being didactic, how my thesis fits within the current environmental movement, and how it helps stretch the definition of what is considered eco-writing.

This thesis consists of three illustrated picture …

Gene Ontology-Guided Force-Directed Visualization Of Protein Interaction Networks, James Lowell King

CCAC Theses and Dissertations

Protein interaction data is being generated at unprecedented rates thanks to advancements made in high throughput techniques such as mass spectrometry and DNA microarrays. Biomedical researchers, operating under budgetary constraints, have found it difficult to scale their efforts to keep up with the ever-increasing amount of available data. They often lack the resources and manpower required to analyze the data using existing methodologies. These research deficiencies impede our ability to understand diseases, delay the advancement of clinical therapeutics, and ultimately costs lives.

One of the most commonly used techniques to analyze protein interaction data is the construction and visualization of …

Gamespect: A Composition Framework And Meta-Level Domain Specific Aspect Language For Unreal Engine 4, Benjamin Jay Geisler

CCAC Theses and Dissertations

Game engine programming involves a great number of software components, many of which perform similar tasks; for example, memory allocation must take place in the renderer as well as in the creation routines while other tasks such as error logging must take place everywhere. One area of all games which is critical to the success of the game is that of game balance and tuning. These balancing initiatives cut across all areas of code from the player and AI to the mission manager. In computer science, we’ve come to call these types of concerns “cross cutting”. Aspect oriented programming was …

The concluding analysis of the research presented here strongly stands in support of Comprehensible Input as an effective teaching method. It yields equivalent or improved …

Estimating Juvenile Recruitment Of Elk In An Occupancy Modeling Framework, Mateen A. Hessami

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Juvenile recruitment is a key parameter in understanding ungulate population dynamics. Traditional methods in population composition surveys, such as estimating young: adult-female ratio’s, can be precluded by cost, safety, and feasibility. The use of remote cameras provides a potentially cutting-edge tool to apply to wildlife population estimation techniques. While the prevalence of remote cameras in ungulate studies has increased, few studies have used cameras to estimate vital rates, such as recruitment or survival. Here, we tested the potential of remote cameras to estimate calf: cow ratios and calf survival of elk (Cervus elaphus) using the Royle-Nichols (2003) occupancy …

Eating Insects: A Community Action Toolkit, Lily X. Chumrau, Charlotte Langner, Freya Sargent, Ellen Sears, Mary Mccormick

Undergraduate Theses, Professional Papers, and Capstone Artifacts

The world’s human population has risen exponentially over the last 100 years and is expected to reach nine billion by 2050. Ensuring food security and resource sustainability is of global concern. The United Nations Food and Agriculture Organization endorses insect farming as an alternative to cattle, pork, sheep, and poultry industries because of their higher food conversion rate. Insect farming requires less arable land, less water, and produces less greenhouse gases than traditional livestock. The practice of eating insects, known as entomophagy, is not a new idea as two billion people around the world include insects in their diets. Unfortunately, …

The Gamification Of Modern Dating: A Feminist Analysis, Hannah Travis

Scripps Senior Theses

My project gg is a digitally rendered 360° animation of a tech-filled bedroom, accompanied by a joystick that can be used to navigate the 3D space. A visual comparison between multimedia games and modern dating culture, the bedroom scene draws parallels between the prioritization of male perspectives in fine art and digital media and the social prioritization of “masculine” qualities like logic over emotional vulnerability in the initialization of interpersonal relationships. My project investigates human motivations for playing games, both in the literal and idiomatic sense, using stereotypically feminized colors and symbols, to reclaim the patriarchal world of gaming for …
