On The Scientific Stature Of Data Science: The Epistemological Unicorn, Ernest Fokoue

Articles

Data Science has ignited unprecedented academic, industrial, and pedagogical fervor, yet its status as a \textit{science} in the classical sense---comparable to physics or biology---remains profoundly unsettled. This article interrogates the epistemological foundations of Data Science by examining its hybrid theoretical lineage, from the Universal Approximation Theorem to the No-Free-Lunch Theorems, with special emphasis on the fundamental Bayesian optimality results for both regression and classification. We argue that Data Science is in a vigorous \textit{gestational period}, characterized not by an absence of principles but by a creative tension between empirical pragmatism and deep mathematical theory. The Cross-Validation score emerges as the …

Learning Ordinal Geometry: Semantic–Aware Kernels For Ordered Categorical Data, Ernest Fokoue

Articles

Ordinal data arise ubiquitously in survey research, psychology, medicine, economics, and recommender systems, yet kernel methods for such data typically rely on either nominal encodings or arbitrary numeric codings. The former discards order information; the lat- ter imposes a fictitious metric structure. This paper develops a principled framework for kernel design on ordinal scales and introduces a new class of Semantic–Aware Ordinal Ker- nels (SAOK) that simultaneously capture ordinal order and semantic proximity between categories. We begin by formalizing order–preserving embeddings of finite chains and characterizing a broad family of chain distances that are conditionally negative definite. Through Schoen- berg …

Saturated Hierarchical Atomic Incremental Learning (Shail): A Behavioral Learning Perspective On Staged Mastery And Saturation, Ernest Fokoue

Articles

We introduce Saturated Hierarchical Atomic Incremental Learning (sHAIL), a learning paradigm in which complex tasks are approached through a sequence of simpler atomic subtasks, each mastered to saturation before progression. The central mechanism is a saturation criterion that detects when learning dynamics enter a plateau region, triggering consolidation and subsequent ascent to a higher level of task complexity. We develop a theoretical framework for sHAIL and show that it naturally gives rise to \emph{staircased convergence}: alternating phases of rapid improvement and genuine plateau. Within each level, classical convergence guarantees apply under standard smoothness conditions, while the hierarchical transitions are driven …

On Fibonacci Ensembles: An Alternative Approach To Ensemble Learning Inspired By The Timeless Architecture Of The Golden Ratio, Ernest Fokoue

Articles

Nature rarely reveals her secrets bluntly, yet in the Fibonacci sequence she grants us a glimpse of her quiet architecture of growth, harmony, and recursive stability \citep{Koshy2001Fibonacci, Livio2002GoldenRatio}. From spiral galaxies to the unfolding of leaves, this humble sequence reflects a universal grammar of balance. In this work, we introduce \emph{Fibonacci Ensembles}, a mathematically principled yet philosophically inspired framework for ensemble learning that complements and extends classical aggregation schemes such as bagging, boosting, and random forests \citep{Breiman1996Bagging, Breiman2001RandomForests, Friedman2001GBM, Zhou2012Ensemble, HastieTibshiraniFriedman2009ESL}. Two intertwined formulations unfold: (1) the use of normalized Fibonacci weights -- tempered through orthogonalization and Rao--Blackwell optimization -- …

Fibonacci-Driven Recursive Ensembles: Algorithms, Convergence, And Learning Dynamics, Ernest Fokoue

Articles

This paper develops the algorithmic and dynamical foundations of recursive ensemble learning driven by Fibonacci-type update flows. In contrast with classical boosting Freund and Schapire (1997); Friedman (2001), where the ensemble evolves through first-order additive updates, we study second-order recursive architectures in which each predictor depends on its two immediate predecessors. These Fibonacci flows induce a learning dynamic with memory, allowing ensembles to integrate past structure while adapting to new residual information. We introduce a general family of recursive weight-update algorithms encompassing Fibonacci, tribonacci, and higher-order recursions, together with continuous-time limits that yield systems of differential equations governing ensemble evolution. …

Should The Ordinary Income Rate Apply To Carried Interest?, Reuven S. Avi-Yonah

Articles

In 2008 professor Victor Fleischer published a famous article entitled “Two and Twenty: Taxing Partnership Profits in Private Equity Funds.” The article explained that: Private equity fund managers take a share of the profits of the partnership as the equity portion of their compensation. The tax rules for compensating general partners create a planning opportunity for managers who receive the industry standard “two and twenty” (a two percent management fee and twenty percent profits interest). By taking a portion of their pay in the form of partnership profits, fund managers defer income derived from their labor efforts and convert it …

Virtual Humans In Virtual Reality: A Scoping Review On Sociability, Fidelity, And Expression, J K Sangeeth Chandran, Marisa Llorens Salvador, Cathy Ennis

Articles

Introduction:

Virtual reality (VR) systems have evolved significantly over the past decade, enabling immersive experiences with enhanced realism and interactivity. This has motivated an interest in socially oriented applications. As user proxies, Virtual Humans (VHs) play essential roles in such applications. However, despite technological advancements, achieving realistic, expressive, and socially responsive VHs continues to present design and implementation challenges. In this scoping review, we present the state-of-the-art of VR VHs, examining the impact of VHs on the user experience.

Methodology:

We reviewed 59 papers retrieved from five databases across three core themes: the implementation and impact of VH facial expressions, …

Surgical Removal Of Visceral Adipose Tissue Has Therapeutic Benefit In Male Appnl-F Mice, Samuel A. Mcfadden, Yimin Fang, Kathleen Quinn, Mackenzie R. Peck, Jenelle E. Chapman, Tiarra Hill, Andrzej Bartke, Erin R. Hascup, Kevin Hascup

Articles

Purpose:  Visceral white adipose tissue (vWAT) accumulation causes systemic inflammation, insulin resistance, metabolic syndrome, and senescent cell accumulation that are risk factors for Alzheimer’s disease (AD). Visceral fat removal (VFR) improves metabolism and reduces pro-inflammatory cytokines.  We hypothesized that VFR removal in AD mice would improve metabolism and cognition.

Methods:  Male and female APP^NL-F mice underwent sham or vWAT surgical resection (periovarian or epididymal and perirenal) at 4 (pre-symptomatic) and 16 (symptomatic) months of age to understand interventional and therapeutic effects, respectively.  At 18 months of age, glucose metabolism and novel object recognition (NOR) memory were assayed followed by …

Resurrecting Immigration Releases, Lindsay Nash

Articles

The nation’s “mandatory” immigration-detention laws sustain its largest civil-imprisonment system—and just radically expanded in scope and breadth. These laws consign broad swaths of suspected noncitizens to no-bail pretrial detention, denying tens of thousands of people facing civil regulatory charges any chance to prove they need not be detained. These laws turn split-second arrest decisions into jail sentences. They force people to give up meritorious claims. And they confound the historic presumptions—liberty, innocence, prosecutorial discretion, and bail—that undergird other pretrial-detention regimes. Although mandatory immigration detention conflicts with fundamental constraints on analogous detention regimes, the Supreme Court has treated it as exceptional …

Selecting Without Replacement From A Population Of Bands Of Serially Connected Objects, James E. Marengo, Dominick Banasik, Joseph Voelkel, David L. Farnsworth

Articles

The sampling procedure from a finite population of objects that are serially attached into bands is described and analyzed. One object is randomly selected and removed at a time, which results in that object’s band being broken into two bands or shortened by one object. The main result gives the probability of choosing an object that is part of a band of serially connected objects of any specified size at each stage of the selection process.

Feedback Loops: Half-Life Your Message, Patrick Barry

Articles

I sometimes get asked to design training workshops to help organizations ensure their employees receive the consistent, high-quality feedback needed to develop and improve. A pretty common request is for workshops that give people feedback on their communication styles and push them to become more concise and compelling writers and speakers. Nobody, for example, has ever asked me, “Is there any way you can teach our lawyers to write longer, more rambling emails?” Or “Can you show us how to drone on and on while giving a presentation or running a meeting?”

Flexible Funding Authorities To Support Tribal Climate Adaptation, Monte Mills, Sydney Anderson, Lauren Young

Articles

This project is part of a policy research effort intended to support Tribes, federal agencies, and Tribal and non-Tribal organizations in addressing some of the climate adaptation barriers and needs experienced by Northwest coastal Tribes. Accessing and administering Federal funds is a significant challenge for Tribes. Existing federal funding sources are often accompanied by rigid rules that make it difficult for Tribes to flexibly allocate funds as needed, and include strict qualification criteria that limit Tribal access to funds. Short-term funding cycles can be disruptive to long-term staffing and project needs, and are often misaligned with Tribal priorities.

Equity In Place, Segregation, And The Phillips Neighborhood, Myron W. Orfield

Articles

This Article describes an existential legal and factual conflict about residential segregation. It is centered in a neighborhood a few blocks north of where George Floyd—and more recently Renee Good—were murdered. Five years before Floyd’s murder, the conflict reached a breaking point, resulting in three lawsuits. One involved federal civil rights and two involved state civil rights claims that housing policy was causing deeper residential and educational segregation. Much of this debate was summarized in a series of articles in the journal Housing Policy Debate before the lawsuits were filed.

On one side were proponents of greater residential and educational …

Expanding Astrobiology: The Case For A Lunar Biorepository, Mary Hagedorn, Lynne R. Parenti, Robert A. Craddock, Pierre Comizzoli, Paula Mabee, Bonnie Meinke, Susan Wolf, John C. Bischof, Rebecca D. Sandlin, Shannon N. Tessier, Mahmet Toner, Baptiste Journaux, Robert Ambrose, Garret Fitzpatrick

Articles

Earth’s resources are essential to support an expanding presence beyond the planet. Yet global conflicts, environmental change, and natural disasters threaten ecosystems and biodiversity, putting the integrity of Earth’s ecosystems and its resources at risk. These converging challenges underscore the urgency to develop innovative strategies to conserve Earth’s biodiversity. Astrobiology—seeking to understand life’s origins, limits, and potential beyond Earth—plays a central role in this effort, helping to preserve Earth’s species while also providing critical assets to explore and work in space. A Lunar Biorepository was proposed to hold cryopreserved samples from among the most critical species on Earth. Here, we …

Why Boards Should Have Rotating Contrarians, Dana Brakman Reiser, Claire A. Hill

Articles

Too often, for-profit and nonprofit boards are too passive, deferential or both. Their failures to engage their critical faculties have resulted in serious harms as diverse as Boeing planes crashing and the NRA squandering millions of dollars. This article proposes a simple mechanism to stimulate critical thinking by individual directors and improve overall board dynamics: a designated contrarian position that rotates among members of the board. During her term, the contrarian’s job would be to raise objections to the organization’s proposed actions – or inaction. After their terms, each contrarian would resume her duties as a regular board member, replaced …

Liability For Non-Disclosure In Ipos, Albert H. Choi, Kathryn E. Spier

Articles

A privately-informed entrepreneur may withhold material information from prospective investors who may sue the firm ex post for (alleged) non-disclosure. Absent liability, the entrepreneur has an excessive incentive to withhold bad news and pursue socially-wasteful projects. Liability deters inefficient non- disclosure and prevents capital misallocation. Any damage award received by investors is partially offset by a reduction in equity value. Depending on the likelihood of court error and litigation cost, the socially-optimal damage award may be either zero or the minimum necessary for full deterrence. The private incentive to waive liability may be socially excessive or insufficient. Positive and normative …

Can – And Should – The Un Charter Be Saved?, Steven Ratner

Articles

World leaders from Canada’s Mark Carney to Germany’s Friedrich Merz have announced the demise of the international rules that provided some degree of order to international relations since the Second World War.2 The immediate cause is clear to them and others – a seeming abandonment of international law, and the UN Charter in particular, by the United States government, its chief architect and advocate. The U.S. actions and rhetoric over Venezuela and Iran – wars the United States has started – as well as Greenland and Ukraine seem to have confirmed the worst about the future of international law.

Interpretive Facts: Textualism, Empiricism, And The Law-Fact Divide, Hannah Walser

Articles

This Article offers the first systematic examination of where empirical linguistic evidence should fit in the federal court system's division of labor based on law and fact. I begin by identifying interpretive facts : generalized empirical evidence about how a particular word or phrase has been used by a population of speakers, understood by a population of listeners, or both. Thanks to technological advances in corpus linguistics permitting the quantitative analysis of large numbers of texts, as well as methodological shifts that frame ordinary meaning as an empirical question, such facts are increasingly prominent in statutory and constitutional interpretation cases. …

Adding Family Complications To Birthright Citizenship, Scott Titshaw

Articles

On the first day of his second administration, President Trump issued an executive order purporting to restrict citizenship of U.S.-born children based on their parents’ citizenship or immigration status. In the process, it discriminates between mothers and fathers and adopts genetic definitions of “mother” and “father” to exclude any parent, who is not the child’s “immediate … biological progenitor.”

Courts and scholars have condemned this attempt to restrict birthplace citizenship as a violation of both the Fourteenth Amendment and the Immigration and Nationality Act. Yet there has been little, if any, discussion of the new family-based conditions in the order. …

Family Law Agreement And The New Gender Bargains, June Carbone, Brian H. Bix

Articles

The great family law divide is said to be marriage, as marriage has emerged as a marker correlated with race and socioeconomic status. This article argues that the real family law divide, inside and outside of marriage, is agreement. Family law, and the family court system that implements it, produce agreement when legal rules, societal norms, and family court procedures operate together to encourage shared understandings expressed through statuses such as marriage or parenthood, and legally enforceable agreements. In an increasingly unequal society, the family understandings of the college-educated middle class have moved apart from those much less privileged in …

In Service Of The State: Foreign Financing, Infrastructure, And Imperialism In Tsarist Russia, Christopher A. Hartwell, Paul Vaaler, Boris Vinogradov

Articles

Russia’s imperialism in the nineteenth century has been far less scrutinized than other episodes of great power colonization, but the Tsar’s expansion into the Caucasus was indeed an ongoing imperial project. The movement of Russian troops and settlers was only feasible with the creation of a large railway network, an undertaking for which the Tsarist regime lacked adequate funding. In response, the regime developed a system of state guarantees and incentives to attract foreign investors looking for higher returns and willing to finance railways serving the imperial project. We illustrate this point with a case study of Paris-based Crédit Lyonnais …

Filling The Network Gap In Research Ethics: Analyzing Ethical Issues At Scale In Big Team Science, Susan Wolf, Gillian H. Roehrig, Timothy L. Pruett, Korkut Uygun, Claire Colby Mcvan, Evelyn Brister, Shawneequa L. Callier, Alexander M. Capron, James F. Childress, Rosario Isasi, Andrew D. Maynard, Kenneth A. Oye, Paul B. Thompson, Terrance R. Tiersch

Articles

Scientific research increasingly involves large, multidisciplinary teams networked across multiple institutions to develop new technologies. Despite the rise of complex research networks and big team science, there has been too little analysis to date of the ethical challenges facing these networks. The extensive literature on the ethical issues confronting individual researchers and small teams (the microlevel) and on the larger societal challenges flowing from research and new technology (the macrolevel) leaves a troubling gap in between, at the mesolevel of the research network involved in big team science. Yet the ability of complex networks to conduct research ethically—which is essential …

Ai-Powered Lawyering: Ai Reasoning Models, Retrieval Augmented Generation, And The Future Of Legal Practice, Daniel Benjamin Schwarcz, Sam Manning, J.J. Prescott, Patrick Barry, David R. Cleveland, Beverly Rich

Articles

Generative AI is set to transform the legal profession, though its most promising uses and ultimate effects are still unclear. While AI models like GPT-4 improve efficiency, they can also “hallucinate” and may undermine legal judgment, particularly in complex tasks typically handled by skilled lawyers. This article examines two emerging AI innovations that may mitigate these concerns: Retrieval Augmented Generation (RAG), which grounds AI-powered analysis in legal sources, and AI reasoning models, which structure complex reasoning before generating output. We conduct the first randomized controlled trial assessing these technologies, assigning upper-level law students to complete legal tasks using a RAG-powered …

Grading Machines: Can Ai Exam-Grading Replace Law Professors?, Kevin L. Cope, Jens Frankenreiter, Scott Hirst, Eric A. Posner, Daniel Schwarcz, Dane Thorley

Articles

In the past few years, large language models (LLMs) have achieved significant technical advances, enabling legal-advocacy organizations to adopt them as complements to—or substitutes for—lawyers and other human experts. The role of LLMs in legal education, however, is underexplored. While several studies have examined LLMs’ performance in taking law school exams, finding mixed results, there have been no published studies systematically analyzing LLMs’ competence at one of law professors’ chief responsibilities: grading law school exams. This paper presents results of an analysis of how LLMs perform in evaluating student responses to legal analysis questions of the kind typically contained in …

Rethinking The Fund Termination Sanction, Samuel R. Bagenstos

Articles

Title VI of the Civil Rights Act of 1964 is often referred to as the “sleeping giant” of civil rights law. It is a “giant” because it prohibits any form of race discrimination engaged in by any recipient of federal financial assistance, and because the remedy set forth in the statute for a violation is the termination of federal funds. And it is “sleeping” because, except for a brief moment during the desegregation era, the federal government had never seriously attempted to terminate a recipient’s federal grants for a violation of the statute. Nor had the federal government seriously attempted …

W. E. B. Du Bois And Black People's Blocked March Toward Equality, Michael Tonry

Articles

W. E. B. Du Bois, a man of extraordinary gifts, in 1897–1898 completed a survey of the lives of 9675 Black Philadelphians. Black inequality and crime were, he observed, products of interactions among legacies of historic racism, contemporaneous discrimination, and conditions of deep structural disadvantage. Criminologists have long documented the criminogenic effects of structural disadvantage, concluding that they are race-neutral, affecting people of all “races” in much the same way, but have only recently, like Du Bois, acknowledged that the background conditions of Black people's lives are not race-neutral. The policy implications are straightforward: Aggressively challenge invidious bias, identify and …

The Durability Of Protections Against Abuse At Interpol Amidst Rising Authoritarian Pressures, Kristina Daugirdas

Articles

Over centuries and across continents, authoritarian governments have demonstrated a large appetite for international cooperation to target political opponents across borders. In 1851, the “first modern police organization”—the Police Union of German States, whose members included Austria and Prussia—was established “with the express purpose of policing the political opposition of established autocratic regimes.” During the 1970s and early 1980s, military regimes in South America participated in a secret scheme known as Operation Condor to coordinate their efforts to suppress subversion. A recent analysis of twenty-nine “hard authoritarian” regional organizations found that twenty-five were engaged in police cooperation. The Shanghai Cooperation …

Legalistic Noncompliance, Daniel Deacon, Leah Litman

Articles

Will the executive branch comply with court orders? That question has garnered a considerable amount of attention over the first few months of the second Trump administration. But what does it mean to comply? And what if a form of noncompliance is already occurring?

This Article documents an emerging practice that has dominated the second Trump administration's approach to unfavorable court rulings, a practice this Article calls legalistic noncompliance. Legalistic noncompliance occurs when the administration uses the language of the law as cover to claim that it is complying with court orders when in fact it is not. Drawing …
