The Great Scrape: The Clash Between Scraping And Privacy, Daniel J. Solove, Woodrow Hartzog

Faculty Scholarship

Artificial intelligence (AI) systems depend on massive quantities of data, often gathered by “scraping”—the automated extraction of large amounts of data from the internet. A great deal of scraped data contains people’s personal information. This personal data provides the grist for AI tools such as facial recognition, deep fakes, and generative AI. Although scraping enables web searching, archiving of records, and meaningful scientific research, scraping for AI can also be objectionable and even harmful to individuals and society.

Organizations are scraping at an escalating pace and scale, even though many privacy laws are seemingly incongruous with the practice. In this …

A Proposed Ehrenfeucht-Fraïssé Game Model For Natural Language Processing Generative Adversarial Networks, Don Li

Anthós

Large Language Models (LLM’s) (e.g., ChatGPT) constitute both a significant research area and commercial application of AI. Current major LLM’s are built on Generative Pre-Trained Transformer (GPT) neural network architecture to perform natural language processing (NLP) tasks. Generative Adversarial Network (GAN) is another popular neural network architecture, which leverages a zero-sum game between constituent neural networks within the architecture to train the GAN, and is widely used for visual data applications. This article proposes a new GAN architecture for NLP: an EF-GAN whose underlying algorithm uses Ehrenfeucht–Fraïssé (EF) games, a game-theoretic approach from model theory to determine elementary equivalence of …

Retrenchment By Division: The New Law And Politics Of Parental Rights, Mary Ziegler, Maxine Eichner, Naomi Cahn

Faculty Publications

For the past century, the Supreme Court has repeatedly affirmed the importance of parents’ rights to direct their children’s upbringing and education. Yet suddenly the rhetoric of parental rights is being used to ground a broad range of claims on issues such as what can be taught in public schools, when minors can access gender-affirming care, or who will be punished for helping minors travel for abortion care. Why have parental-rights claims surged so visibly in contemporary law and politics? And are all the new arguments made under the banner of parental rights equally rooted in constitutional precedent?

A Patent System For Temple Grandin, Andrew Chin

Faculty Publications

This article explores the intersection of neurodiversity and innovation through the lens of Temple Grandin’s contributions to livestock handling systems and her philosophical alignment with the U.S. patent system. Drawing on cognitive research by Simon Baron-Cohen, archaeological insights from Penny Spikins, and personal reflections, I argue that autistic cognitive styles—characterized by heightened “folk physics” aptitudes and visual thinking—have historically driven technological progress. Grandin’s patented inventions, motivated by sensory-based empathy for animals, exemplify how neurodivergent inventors seek to embed their conceptions of ethical utility into the nation’s technological infrastructure. The article critiques modern patent litigation trends, advocating instead for a system …

Faculty Research, Scholarly, and Creative Activity

Understanding the physiological processes underlying cardiovascular disease (CVD) requires examination of endothelial cell (EC) mitochondrial networks, because mitochondrial function and adenosine triphosphate production are crucial in EC metabolism, and consequently influence CVD progression. Although current biochemical assays and immunofluorescence microscopy can reveal how mitochondrial function influences cellular metabolism, they cannot achieve live observation and tracking changes in mitochondrial networks through fusion and fission events. Holotomographic microscopy (HTM) has emerged as a promising technique for real-time, label-free visualization of ECs and their organelles, such as mitochondria. This nondestructive, noninterfering live cell imaging method offers unprecedented opportunities to observe mitochondrial network dynamics. …

On Entityness And Takeovers: Acquisition Valuation, Theory Of The Firm, And Coase’S Error, Robert J. Rhee

Vanderbilt Law Review

This Article advances a theory of entityness that theorizes the firm and its relationship to the acquisition premium. This theory is the first scholarly analysis to construct a general model of takeover valuation by integrating the modern finance theory of asset value and a corrected Coasean theory of the firm. The acquisition premium is an enigma. Acquirers must pay it. But why? Isn’t the market price tethered to fundamental value through an efficient market? This enigma reveals a key insight about firms. The theory of entityness postulates that the acquisition premium is compensation for a capitalized asset intrinsic in the …
