Process Improvement Of Cu(Ii)-Trymethylamine-Based Active Clay Measurement Test And Total Clay Measurement Test, Christopher Michael Remily

Masters Theses

Foundry work requires a mold made of a mixture of sand, “active clay” to absorb gas, and binders to combine the two and hold the molds shape. When the metal is melted to be poured into the mold, the solubility dramatically increases, causing gas to be temporarily dissolved in the metal. This gas causes small surface pits to form once the metal cools, causing part failure. This causes the need to absorb the gas. Since the clay is used in the process, there needs to be a way to determine how much remains active, which is done with a dye …

Growing Agriculture Literacy’S Presence In America’S Classrooms, Emily Stone

Journal of Food Law & Policy

“Americans, as a whole, were at least two generations removed from the farm and did not understand even the most rudimentary of processes, challenges, and risks that farmers and the agricultural industry worked with and met head-on every day.” This quote perfectly describes the mindset of agriculture stakeholders in 1981 as they began to realize the drastic steps our education system had taken away from using principles of agriculture in K-12 education. As they saw it, Americans were moving out of rural America, away from farms, and becoming less connected to the food they daily consumed. Simultaneously, the education system …

Chewing The Welfare Cud: A Digested Analysis Of A Consumer Versus Producer-Defined Standard Of Welfare Practices In Animals Raised For Human Consumption, Caitlin C. Robb

Journal of Food Law & Policy

Since the eighteenth century, animal well-being remains a concern for American citizens. Yet, underlying this concern is the thought that while humans should not be cruel to animals, animals are still private property subject to human ownership. Therefore, multi-faceted questions of what constitutes “animal welfare” find a place in modern American debate. One such question becomes: should the producer or the consumer define welfare practice standards of animals raised for human consumption?7 This note provides an answer to this question by first analyzing the robust history of animal welfare in the United States, along with the domestic and international impact …

Instrumentality: How We Develop Relationships With Objects And People, Nathaniel Bee

Undergraduate Honors Capstone Projects

There are many different types of relationships a person will have throughout their life, each being given varying levels of authenticity, weight, and care. One’s attention is primarily placed upon the meaningful relationships in one’s life, but often deeper consideration of one’s “lesser” relationships is neglected. Networking and professional relationships are often impersonal. Family members will often lie to each other in favor of avoiding conflict. The emotional labor of service workers often goes underappreciated and undercompensated. Careers in the political sphere revolve heavily around maintaining a positive public image, and there are well-observed disparities between politicians’ stated values and …

Fair Canonical Correlation Analysis, Zhuoping Zhou, Davoud Ataee Tarzanagh, Bojian Hou, Boning Tong, Jia Xu, Yanbo Feng, Qi Long, Li Shen

Faculty, Staff and Student Publications

This paper investigates fairness and bias in Canonical Correlation Analysis (CCA), a widely used statistical technique for examining the relationship between two sets of variables. We present a framework that alleviates unfairness by minimizing the correlation disparity error associated with protected attributes. Our approach enables CCA to learn global projection matrices from all data points while ensuring that these matrices yield comparable correlation levels to group-specific projection matrices. Experimental evaluation on both synthetic and real-world datasets demonstrates the efficacy of our method in reducing correlation disparity error without compromising CCA accuracy.
