The Effects Of Poor Maternal Nutrition On Offspring Muscle Metabolism, Dominique Martin

Master's Theses

Poor maternal nutrition during gestation alters offspring muscle composition, fiber number, postnatal growth, and stem cell function. Additionally, poor maternal nutrition impacts offspring whole body and stem cell metabolism. We hypothesized that over- or restricted-feeding during gestation would alter muscle myoblast metabolism as well as offspring Longissimus dorsi muscle (LD) metabolome. Pregnant Western White-faced ewes (n = 47) were individually fed 60% (RES), 100% (CON), or 140% (OVER) of NRC requirements starting at d 30.2 ± 0.2 of gestation. At d 90 and 135 of gestation, ewes were euthanized for fetal muscle collection. Another group of ewes were allowed to …

Detecting A Probiotic Product Within The Gut Of Broiler Chickens, Anneka Pisula

Master's Theses

As of January 2017, the U.S. poultry industry banned the use of antibiotics and now relies on alternatives such as probiotics to help protect animal health. Although probiotic use is not a new concept in the poultry industry, identifying the best combination of bacterial strains to generate an effective probiotic formula requires further investigation. This study aimed to detect a probiotic product of four bacterial strains (Pedioccoccus acidilactici, Pediococcus pentosaceus, Lactobacillus plantarum, and Bacillus subtilis) in a feeding trial with broiler chickens. Birds given the probiotic were predicted to show an improved growth performance with …

Evaluation Of Endothelial Cell Responses To Elevated Glucose, Gabriella Sugerman

Master's Theses

Developing a tissue-engineered Blood Vessel Mimic (BVM) to represent diabetic macrovascular disease could expedite design of new vascular devices specifically tailored to diabetic patients. In contribution toward this model, this thesis assessed Human Umbilical Vein Endothelial Cell (HUVEC) responses to high glucose conditions. Interleukin 6 (IL-6) and Cluster of Differentiation 36 (CD36) were selected to signify oxidative stress activity, a hallmark of diabetic macrovascular disease. Next, activity of potential reference genes B2M, HPRT1, and ACTB was assessed. All genes were found to exceed acceptable variability, so the E-ΔC T method of data analysis was selected. Next, cellular responses to high …

Modifying The Mineral Profile Of Crickets (Acheta Domesticus) Using A Supplemented Diet, Rhianne Morgan Le Maxwell

Master's Theses

Captive insectivores may consume invertebrates as all, or part of their overall diet. The challenge with feeding captive insectivores involves the limited number of invertebrate species that are commercially available, and the lack of key nutrients provided by these insects. Among these insects, a naturally occurring low concentration of calcium and an inverse calcium to phosphorus ratio may put insectivores at the risk of developing hypocalcemia. A strategy to correct this nutrient imbalance involves supplementing the insect diet with high concentrations of targeted nutrients – a term referred to as gut-loading. Current industry guidelines recommend feeding a supplemented diet for …

Creating Renewable Energy Through The Pairing Of Wastewater Remediation And Biofuel Production With Two Species Of Microalgae, Laura Brown

Master's Theses

In this study, two species of microalgae, Scenedesmus sp. isolated locally and Chlorella sorokiniana (UTEX 1230) were grown in municipal wastewater collected from Stennis Space Center, MS in order to assess whether or not the microalgae could remediate the wastewater into a clean and usable form while also producing the biomaterials necessary for fuel and other useful byproducts. Each species was cultured in 16 ˚C and 30 ˚C to assess functional variabilities at different times of the year. The microalgae’s ability to decrease nutrient concentrations in the wastewater and produce lipids and protein was assessed at three different growth stages: …

Metabarcoding Analysis Of Prey Composition Of The Copepod Calanus Finmarchicus In Regions Of The North Atlantic Ocean, Heidi Yeh

Master's Theses

The copepod Calanus finmarchicus occupies a pivotal position in the pelagic food web of the North Atlantic Ocean. Prey choice and predator-prey dynamics at this trophic level can influence energy transfer through the ecosystem. To examine the copepod prey composition and test the hypothesis that C. finmarchicus exhibit spatial variation in diet across four basins of the North Atlantic, this study used metabarcoding analysis (high throughput sequencing of orthologous gene regions) to analyze the gut contents of C. finmarchicus. Zooplankton net samples were collected during a 2013 cruise of the R/V GO Sars in the Norwegian, Icelandic, Irminger, and Labrador …

The Effect Of Destoning And Enzymatic Pretreatments On The Biofuel Production From Olive Cake, Patrick Tai

Master's Theses

More than 16,000 tons of olive cake was produced in the United States in 2017. Olive cake is a by-product of olive oil extraction, which has limited animal feed potential, and poses an environmental threat when landfilled due to its high organic load and polyphenol content. This residue has potential for biofuel (bioethanol and biomethane) production because it is rich in polysaccharides such as pectin, hemicellulose, and cellulose. Yet, olive cake contains olive stones that can impede its conversion to biofuel. Therefore, two methods of destoning, centrifugation and screening by horizontal screw press, were first compared. Both methods removed an …

Relationship Between Aerobic Capacity And Episodic Memory In Older Adults, Nicole Henderson

Master's Theses

The goal of this research was to examine the relationship between aerobic capacity and memory in older adults. Prior research demonstrated an age-related decline in episodic memory (memory for episodes and events), which may be partially due to a decreasing ability to engage in pattern separation – the ability to form new memories that are sufficiently distinct from prior memories. Studies in rodents suggested that aerobic exercise may improve pattern separation abilities in older animals, but similar research in humans is lacking. Here, I investigated whether individual differences on a memory test that taxes pattern separation were associated with differences …

Effects Of A Preschool Arts Curriculum On Social And Emotional Competence, Sarah Rose Henderson

Master's Theses

This study investigated the extent to which low-income preschool children’s social, emotional, and behavioral competence improved after engaging in a six-week-long arts program. Participants included 46 students of three, four, and five years of age in two low-income, state-funded classrooms in the San Francisco Bay Area. Analyses of children’s scores on SCBE-80 measures of Social Competence and Egotistic-Prosocial showed statistically significant change from the pretest to the posttest. Teacher survey report of students’ frequency in social adaptation and enjoyment of the arts suggested that teachers observed social improvements in the classroom that were consistent with SCBE-80 results in Social Competence. …

Analysis Of Potential Vermicompost Market In California, Jason Alan Thomas

Master's Theses

Vermicompost transforms agricultural waste into a high quality soil amendment, though market acceptance remains in its infancy. This study examines how growers’ willingness to pay for vermicompost is affected by grower’s crop, region, income per acre, knowledge level of vermicompost and compost, previous use of compost, and the willingness to pay for compost. The survey results pulled together 223 responses from California growers. It was discovered growers’ had less knowledge of vermicompost than compost but were willing to pay more for vermicompost. There was statistical difference amongst the responses. It was shown the market value per ton of vermicompost lies …

Effect Of Aquaponic Vs. Hydroponic Nutrient Solution, Led Light Intensity And Photoperiod On Indoor Plant Growth Of Butterhead, Romaine And Kale (L. Sativa, B. Oleracea), Sean M. Foster

Master's Theses

Vertical farming has been proposed as a solution for providing food security for an increasing, urbanized human population. Light-emitting diode (LED) technology has become increasingly affordable and efficient, making it an ideal choice as artificial lighting for indoor farms. Still largely undiscovered parameters are the optimal plant varieties and types of production systems for plant growth, profit, and human nutrition. Aquaponics may be able to provide sustainable animal protein for vertical farms, increasing their ability to provide more substantial nutrition to consumers. This research aimed to better understand vertical farming as a food production system, and to determine if aquaponics …

Foraging Ecology Of Parrotfishes In The Greater Caribbean: Impacts Of Specialization And Dietary Preferences On Marine Benthic Communities, Madelyn V. Roycroft

Master's Theses

Coral reefs are one of the world’s most diverse yet heavily impacted marine ecosystems. As a result of many direct and indirect stressors, coral reefs have experienced major degradation over the last several decades. Declines in coral reefs in the Caribbean have been particularly acute and generally associated with the loss of key herbivores and an increase in algae. Herbivorous fishes such as parrotfishes can positively impact coral reefs by removing algae that compete with corals for light and space. However, many parrotfishes are also important coral predators. Predation on corals, known as corallivory, can adversely affect coral growth, reproduction …

Pink And Dude Chefs: Effectiveness Of An After-School Nutrition Knowledge And Culinary Skills Program For Middle School Students To Increase Fruit And Vegetable Consumption, Alyssa S. Vaziri

Master's Theses

The rate of overweight and obesity among adolescents aged 12-19 years has more than tripled since 1980, and disproportionately impacts low-income and marginalized populations. Reduction in adolescent obesity rates may result in decreased health risks, decrease healthcare costs, and increased quality of life. Effective intervention methods for adolescent participants have incorporated nutrition knowledge and culinary skill building into afterschool programs. This study examines whether building knowledge, skills, and confidence through a culinary intervention can improve adolescent participants’ choices of healthful foods through increased fruit and vegetable intake.

Pink and Dude Chefs (PDC) is an afterschool nutrition education and culinary skills …

Influencing Exploration In Actor-Critic Reinforcement Learning Algorithms, Andrew R. Gough

Master's Theses

Reinforcement Learning (RL) is a subset of machine learning primarily concerned with goal-directed learning and optimal decision making. RL agents learn based on a reward signal discovered from trial and error in complex, uncertain environments with the goal of maximizing positive reward signals. RL approaches need to scale up as they are applied to more complex environments with extremely large state spaces. Inefficient exploration methods cannot sufficiently explore complex environments in a reasonable amount of time, and optimal policies will be unrealized resulting in RL agents failing to solve an environment.

This thesis proposes a novel variant of the Actor-Advantage …

Impact Of Cooperative Membership On Members' Household Economies: The Case Of Chiapas Coffee Farmers, Stephen Pitts

Master's Theses

Coffee producers typically sell raw coffee beans as the first step in a global value chain. Recently, groups of producers have formed coffee cooperatives that attempt to regain market power by integrating the other steps of the value chain. This study uses matching to estimate the effect of membership in one such cooperative on the household economy of indigenous coffee producers in the state of Chiapas, Mexico. It contributes to the literature by considering new determinants of participation and outcomes of interest. First, social capital at the individual and village level is correlated with cooperative membership more than other demographic …

Sweden's Great Escape: Industrialization And The Changing Productivity Cost Of Winter, Charlotte Taylor, Jesse Anttila-Hughes

Master's Theses

We combine a paleoclimate reconstruction of the North Atlantic Oscillation (NAO)- a key determinant of Scandinavian winter intensity- with four centuries of historical production data from Sweden, to examine the changing influence of climate variability on production over time. We find the colder, drier winters associated with the negative phase of the NAO led to reduced economic production for much of Swedish history, and that this relationship changed with development: during industrialization, Sweden underwent a transition from ‘level’ effects, where harsh winters lowered average incomes, to ‘growth’ effects, where it reduced growth in improving living standards. Post-industrialization, neither ‘level’ nor …

Boosting Demand For Biofortified Foods: The Case Of Orange Fleshed Sweet Potato Bread In Tamale, Ghana, Tchassanty Ouro-Gbeleou

Master's Theses

Abstract: In the context of introducing biofortification of staple crops as a food-based approach to combat micronutrient malnutrition in Sub Saharan Africa (SSA), we carried out a survey in Tamale, Ghana to elicit consumers’ preference of and willingness to pay for one of the highly nutritious biofortified staple crop processed product: the Orange Fleshed Sweet Potato (OFSP) bread. Our results indicate that scores of respondents in the sample show preference for OFSP bread. The most important determinants of OFSP bread preference are its sweet taste and soft texture and consumers are willing to pay 0.634 pesewas more for the attribute …

An Economic Valuation Of Biodiversity: Measuring Willingness-To-Pay For Quinoa Conservation In Peru, Craig Scott

Master's Theses

Peru is facing increasing homogenization of traditional crops as a result of international market pressures. Destruction of the genetic resource base creates vulnerability to disease, climate, and pest shocks which threaten food security and the economic future of Peru’s agricultural sector. This paper aims to determine whether informational priming on the non-market value of national identity is sufficient to change the willingness to pay for agro biodiversity programs among the Peruvian general population in both urban and rural areas. A choice set willingness to pay experiment combined with choice rankings and randomized priming measures how much individuals are willing to …

Incentives And Teacher Effort: Evidence From Lagos, Nigeria, Simileoluwa Adebajo

Master's Theses

According to recent research (Hattie, 2003), teachers contribute to around 30% of the overall variation in student achievement and success – more than any other influencing factor. This study seeks to understand how different types of incentives (monetary, near monetary and non-monetary incentives) influence the “effort” of public school teachers as perceived by the students in Lagos, Nigeria using a novel measurement tool – the teaching effectiveness survey – to measure the teachers’ outcomes. Using a randomized field experiment where students evaluate the changes in their teachers’ effort with a standard teaching effectiveness survey and differences in differences estimation, we …

Patriarchal Norms, Bargaining, And Gendered Attitudes On Intimate Partner Violence, Anna Eckenrode

Master's Theses

How do the underlying mechanisms of social norms and bargaining power relate to the acceptance of intimate partner violence within households? How do short run and long run determinants of gender norms affect attitudes toward IPV? This study begins to decompose the dynamics of the acceptance of IPV within couples using data from the Demographic Health Survey, as well as examine the relationship in the context of patriarchal societies using data from the Ethnographic Atlas. I find that females are more accepting than males of intimate partner violence, and females becoming more educated is associated with her being less accepting …

The Impacts Of Natural Disasters On Educational Attainment: Cross-Country Evidence From Macro Data, Lois Onigbinde

Master's Theses

Do natural disasters impact educational attainment? Education as a paramount factor of economic development suffers from the uncontrollable effects of these increasing events from storms to floods, earthquakes to wildfires. Globally, educational resources are destroyed, directly and indirectly, students and teachers are displaced or killed, parents’ income is affected because of natural disasters. Investments in human capital for rich- and low-income countries are exposed to the uneven impact of natural disasters that adjusts household and country-level decisions, leaving them to short and long-run losses. Exploring the influence of natural disasters on secondary school attainment across a sample of 85 countries …

Impact Of Innovative Menstrual Technology And Awareness On Female Empowerment Outcomes In Rural Nepal, Anjali Limbu

Master's Theses

In developing countries, menstruation poses two significant challenges for females. First, the resources required for periods are expensive for those in low-income communities. Hence, the absence of such menstrual products lowers females’ access to schooling and employment. Next, periods are also heavily stigmatized – especially in poorer or rural areas. Such taboos surrounding menstruation negatively impacts females’ psychological development and hamper their prospects of socialization. Thus, to analyze this issue, we ran a randomized control trial in Nepal, where we provided reusable menstrual pads and / or health seminar to 312 schoolgirls and 100 of their mothers. Our outcomes demonstrate …

What’S At Steak? The Political Discourse Of Emissions Intensity And Implications Of Animal Agriculture, Kalyn Simon

Master's Theses

This thesis analyzes the international discourse of greenhouse gas emissions in relation to livestock production. Specific government ministries, research institutes, and multilateral organizations are framing a new strategy to mitigate emissions by using emissions intensity metrics. Emissions intensity is a ratio comparing emissions produced per unit of animal product as oppose to measuring absolute emissions. This research is acknowledged as a win-win scenario which allows for a reduction of greenhouse gas emissions while continuing production more efficiently. This thesis outlines the emergence of this metric in international discourse and the implications this shift has on the livestock sector globally. Ultimately, …
