For my honors thesis research project, I was interested to learn more about why not everyone purchases fair trade products. The goal of this project is to research more about if there is a lack of awareness regarding fair trade products? And if there were more awareness would people seek out fairly traded products? This paper highlights what I learned about fair trade products as well as what I did to educate people in my community on fair trade.

In cold chain tracking systems, accuracy and flexibility across different temperatures ranges plays an integral role in monitoring biospecimen integrity. However, while two common cold chain tracking systems are currently available (electronic and physics/chemical), there is not an affordable cold chain tracking mechanism that can be applied to a variety of temperatures while maintaining accuracy for individual vials. Hence, our lab implemented our understanding of biochemical reaction kinetics to develop a new cold chain tracking mechanism using the permanganate/oxalic acid reaction. The permanganate/oxalic acid reaction is characterized by the reduction of permanganate (MnVII) to Mn(II) with Mn(II)-autocatalyzed oxidation of oxalate to CO2, resulting in a pink to colorless visual indicator change when the reaction system is not in the solid state (i.e., frozen or vitrified). Throughout our research, we demonstrate, (i) Improved reaction consistency and accuracy along with extended run times with the implementation of a nitric acid-based labware washing protocol, (ii) Simulated reaction kinetics for the maximum length reaction and 60-minute reaction based on previously developed MATLAB scripts (iii) Experimental reaction kinetics to verify the simulated MATLAB maximum and 60-minute reactions times (iv) Long-term stability of the permanganate/oxalic acid reaction with water or eutectic solutions of sodium perchlorate and magnesium perchlorate at -80°C (v) Reaction kinetics with eutectic solvents, sodium perchlorate and magnesium perchlorate, at 25°C, 4°C, and -8°C (vi) Accelerated reaction kinetics after the addition of varying concentrations of manganese perchlorate (vii) Reaction kinetics of higher concentration reaction systems (5x and 10x; for darker colors), at 25°C (viii) Long-term stability of the 10x higher concentration reaction at -80°C.

An effort to experiment on the novel Usutu virus in pure in silico methods was made to determine conformational changes with non polar point mutations in the amino acid sequence. The first method consisted of creating a Python program to exhaustively identify codons, amino acids, and dinucleotide bridges & nonbridges, including viral characteristics defined by Mollentze in 2021. The second method consisted of creating point mutations to non polar amino acids in deemed key sites of the Usutu virus envelope protein and finding the RMSD from the original structure. This resulted in one of two outcomes - either the experiment showed that the Usutu virus envelope protein is highly resistant to point mutations or in silico methods are inconsistent and biased, leading to inaccuracy.

This thesis asks what the demographics of elite marathon runners are and how they have changed over the past 40 years. Differences in age and nationality of elite marathon runners are examined for the top 100 men’s and women's marathon results each year from 1983 to 2022. This thesis found that 28 is the best age for an elite marathoner to run their best time and that the nations producing top marathon runners are more concentrated now than in the 1980s, prompting the question of whether the resources provided to athletes showing potential are more focused in a select few countries.

As of 2021, over $124 billion of Microfinance has been distributed by the World Bank amongst 140 million borrowers globally. Systems of credit and finance are spread unevenly around the world; in under-developed countries credit bureaus are uncommon and banking networks are more selective regarding loans. Therefore, a system of microloans has emerged, which has targeted small business owners who would not typically qualify for traditional loans from banks and other financial institutions. With approval, microloans typically provide the full loan amount upfront and charge the borrower monthly repayments with interest. On a broad scale, the difference between traditional finance and Microfinance lies within their scope. Microfinance is focused on the individual level to those defined as poor or impoverished by the World Bank, while traditional finance is focused on whole economies or corporations. The primary concern with Microfinance options like this is the higher probability of borrowers defaulting on their loans. This engenders an inescapable cycle of late payments and increased interest rates ultimately resulting in the borrower spending more money than they borrowed. However, Microfinance plans of this type are often the option for individuals stuck in impoverished countries or dismantled economies. At its core, Microfinance is a profit-focused industry that targets individuals that have proved they are not able to repay loans on the conditions of lenders. This arguably sexist industry has presented itself as an opportunity for those less fortunate to obtain funding for dreams currently unattainable given their circumstances. Thus, it is the institutions behind the Microfinance industry that are the problem, not the loans themselves.

Waiting in line for attractions is an unavoidable part of every theme park visit. Many theme park designers have tried ways to make these waits shorter and more enjoyable. Such techniques include offering a separate ‘fast lane’ for certain Guests or creating additional load platforms for higher Guest throughput. Both the queues themselves as well as the attraction’s operation have an enormous effect on how many Guests can experience it in a day, and relatedly, how long they will have to wait for that experience. This paper will utilize both queueing theory and personal work experience to analyze the queues and operations of two attractions at the Magic Kingdom Park: the Tomorrowland Speedway and the Tomorrowland Transit Authority PeopleMover. I use my own personal experience working at these attractions as well as queueing data I recorded to show areas for improvement in queue design and operations, as well as potential solutions to increase efficiency and lower operational costs.

Nike, the largest athletic apparel company in the world, has a very complex wide-reaching supply chain. As pioneers of outsourcing production and products, they have dealt with many challenges and problems since their beginning in 1964. As Nike has faced their controversial history of labor strikes, protests, boycotts, and much more, they began to restructure their business model and supply chain practices. Following this came audits, minimum age requirements, factory condition monitoring, and public disclosures of locations. With these new initiatives and growth in Nike’s supply chain, an overarching analysis of Ports of Lading, Shipment Origins, Ports of Unlading, Shippers/Suppliers, and Carriers can give a glimpse into the world-wide network of their apparel. Finally, through my data analysis and secondary source research, I will explain how Nike's supply chain emerged, adjusted, and changed given different textile regulatory environments over the years.

Wetlands produce approximately one third of total global methane emissions and sequester significant amounts of CO2. Salt marshes make up 5% of total wetland area, and therefore are key factors affecting global methane and CO2 emissions. Many marshes are anthropogenically managed either by diking, draining, impoundment, or otherwise restricting tidal exchange. This causes marsh freshening, increases methane emissions, and releases sequestered carbon, all of which can lead to a warming effect on the climate by the greenhouse effect. We studied the formerly impounded Old County salt marsh, found in the Herring River Estuary of Wellfleet, Massachusetts, USA. The USGS Woods Hole Coastal and Marine Science Center installed two eddy covariance flux towers in the Herring River Estuary. These showed that Old County had low methane fluxes (17 nmol/m2/s) compared to another site in the same estuary (112 nmol/m2/s). The question became; why did Old County experience lower methane emissions? We then did a focused study on the Old County location to investigate. We sampled various biogeochemical parameters including pH, salinity, ORP, dissolved Fe, sulfate, chloride, CH4, DOC, and DIC from pore water samples taken June 2022. We also measured extractable iron from a 2015 archived sediment core at Old County. Specifically, we explored the role of Fe in reducing methane through Fe coupled anaerobic oxidation of methane (Fe-AOM). The porewater depth profiles ranged from 10cm to 242 cm in depth and showed Old County as acidic (pH of 3-6.5), mostly fresh, anoxic, highly reducing, and high in dissolved organic carbon (DOC; 2,000-10,000 μM). I divided the depth profiles into two distinct zones, one above 50 cm and one below 50 cm. Overall, Fe-AOM was likely to occur below 50 cm because dissolved Fe increased as CH4 decreased, which is the expected pattern for Fe-AOM. Also, because the ratio of the calculated methane flux (-0.552 nmol m-2 s-1) to the dissolved Fe (0.072 nmol m-2 s-1) was 7.6, which closely matched the 1 to 8 stoichiometry of the Fe-AOM reactions.

Dental Support Organizations (DSOs) have had a steady increase in popularity since the 2010s. This thesis set out to determine why they have become so popular, and if it would be advantageous to eventually partner with one. It was determined that the steady increase has resulted from a variety of factors including the ability to take advantage of economies of scale, increased cost of schooling, inflated costs of opening a practice, and the wide differentiation of demographics entering the dental industry. The most advantageous factor seemed to be the guaranteed retirement DSOs can provide. Newer DSO models have emerged including IDSOs and DPOs, which provide greater autonomy while incorporating traditional DSO benefits, boosting the popularity of DSOs. These newer models appear to be the best to partner with. In addition, specialty DSOs venture outside of general dentistry to focus on dental specialties like orthodontia and have the potential for higher profitability. DSOs will only become more prevalent with time and are an important tool for any dentist to consider taking advantage of.

The Supply Chain of a company is the most critical component of a business as it directly impacts a company’s ability to deliver products/services to customers is a timely, cost effective method. With this amount of importance, a resilient supply chain is pivotal for positive future earnings in each successive quarter. Two pivotal metrics to gauge a Supply Chain include Production Delays and Excess Inventory. Through in-depth analysis, it was found that these metrics had caused abnormal amounts of price volatility with a stock’s performance. Understanding these metrics, the impact and lesson that COVID had taught, and analyzing earnings transcripts of publicly traded company’s demonstrates the use of Supply Chain health in comparison to company performance. This thesis aims to examine how a company's supply chain affects its performance, by analyzing different metrics and disruptions that have caused significant volatility in the stock market. The objective is to help investors maximize their profitability or reduce their risk by identifying the key factors that impact a company's supply chain.
