How Did Cauchy Prove His Integral Theorem? A Historical Reconstruction For Education Research, José Gerardo Piña-Aguirre, Rosa María Farfán Márquez

Journal of Humanistic Mathematics

In his article “Mémoire sur les Intégrales Définies, prises entre des limites imaginaires” of 1825, Cauchy proves that the integral of a complex function f defined on complex numbers is independent of the path of integration if the function f remains finite and continuous along the chosen path. In contemporary literature that analyzes the mathematics of Cauchy, the specific mathematical process that allowed Cauchy to prove this result is not explicitly presented. The purpose of this manuscript is to communicate a symbolic-algebraic derivation that justifies the narrative argument used by Cauchy to support his proof, thus hopefully filling this gap. …

Gold And Silver In Balance: Khayyam’S Mathematical Analysis Of Binary Alloys, Yousef Yassi, Reza Yassi

Journal of Humanistic Mathematics

The history of titration dates back to Archimedes who established that an object submerged in a liquid displaces an amount of liquid whose weight is equal to the buoyant force acting on the object. Since then, many scientists and engineers have tried to optimize his approach or devise new instruments for titration purposes. Omar Khayyam (1048–1123), in addition to designing a hydro-static balance, developed mathematical approaches for titration of binary alloys, that is, alloys made up of only two elements. Here we explore the different versions of Khayyam’s work on titration given by various sources. We also compare the accuracy …

Translating Trattato Dell'alcibra Amuchabile, Olympia Nicodemi

Journal of Humanistic Mathematics

We present a detailed look at one small section of a premodern algebra manuscript from circa 1365 C.E. The manuscript, Tratatto dell’Alcibra Amuchabile (Anonimo), is written in the Tuscan vernacular, with no symbols, no punctuation, and wildly inconsistent (pre-printing press) spellings. We present some of the hurdles to translating this “rhetorical algebra” followed by an annotated translation of one of its algebra rules, Rule 5, through which we learn the methods and mindset of algebra that preceded and seeded the breakthroughs in algebra of the 16^th century. We also point to some of the significant differences between algebra then …

Coase, Thaler, And Behavioral Economics: Methodological Considerations

Journal of Economics and Finance Education

In their experiments to measure the endowment effect in market settings, Kahneman, Knetsch, and Thaler (1990; hereafter KKT) assessed the assumption of zero transaction costs associated with the Coase theorem. Their study recruited a sample of advanced undergraduate economics students who were placed in a market setting using coffee mugs as real-world goods, under conditions in which there were zero transaction costs. Their results suggested that an endowment effect lowered trading volume, which should not have occurred if Coase theorem worked in practice. We reexamine the research design employed by KKT, as well as their study’s statistical analysis and results.

Back To Basics: Statutory Interpretation And The Demise Of The Dol’S Tip Credit Rule After Loper Bright, William T. Perryman

Missouri Law Review

The Fifth Circuit recently delivered a significant blow to the Department of Labor’s (“DOL”) regulatory authority in Restaurant Law Center v. U.S. Department of Labor, which vacated a rule delineating the permissible scope of non-tip-producing work for employees under the Fair Labor Standards Act (FLSA) for employers claiming a “tip credit.” The challenged regulation—often referred to as the “80/20 rule” with a “30-minute rule” addendum—sought to limit the amount of non-tip-producing work a tipped employee could perform if the employer claimed a tip credit. What renders this decision particularly notable is the Fifth Circuit’s relatively swift invalidation of a long-standing …

Google Geofences: Navigating The Fourth Amendment In The Digital Age, Maverick L. L. Lewis

Missouri Law Review

In December 2018, twenty-three-year-old Jorge Molina was wrongfully arrested for murder based on location data received from a Google geofence—a virtual perimeter around a specific geographic location, created using Google’s location services. Despite law enforcement confirming his alibi within twenty-four hours, Molina spent six days in jail before he was released. As a result, Molina lost his job and car, suffered reputational damage, and was forced to drop out of college. Molina’s stepfather was later arrested and charged for the murder after law enforcement learned he had been using Molina’s old phone, which was still logged into his email. In …

Karni, Antonino Maniaci, Christopher E. Fundakowski, Luca Castellani, Fabiola Incandela, Remo Accorona, Miguel Mayo-Yanez, Martina Violati, Lorenzo Giannini, Niccolo' Mevio, Alberto Maria Saibene

Department of Otolaryngology - Head and Neck Surgery Faculty Papers

BACKGROUND: The management of head and neck cancer relies on multidisciplinary expertise; however, access to tumor boards remains variable. Large language models (LLMs) may support guideline-based decision-making, although performance in complex oncologic scenarios is not well defined.

METHODS: Fourteen synthetic cases based on real tumor board encounters were evaluated. Five blinded comparator arms produced recommendations: a human expert, Non-RAG-GPT-4, Non-RAG-GPT-5, RAG-GPT-4, and RAG-GPT-5. Eight head and neck oncologic surgeons scored each recommendation for appropriateness, clarity, specificity, and feasibility using 5-point Likert scales. Paired permutation testing and inter-rater reliability were assessed.

RESULTS: LLM outputs showed close alignment with expert recommendations. RAG-based …
