Fixed Points In Linear Regression, David L. Farnsworth

Articles

There is a set of points in the plane whose elements correspond to the observations that are used to generate a simple least-squares regression line. Each value of the independent variable in the observations matches up with one of these points, which are called pivot or fixed points. The coordinates of the fixed points are derived, and the properties of the points are explored. All points in the plane that yield each of the fixed points are found. The role that fixed points play in regression diagnostics is investigated. A new mechanical device that uses linkages to model the role …

Lost And Found: The Forgotten Origins Of The “Cruel And Unusual Punishments” Prohibition, John D. Bessler

Articles

The U.S. Supreme Court and legal scholars have long traced the origins of the Eighth Amendment’s prohibition against “cruel and unusual punishments” to the English Declaration of Rights, codified as the English Bill of Rights (1689). The English Declaration of Rights recited that, in King James II’s reign, “illegal and cruel punishments” had been “inflicted,” with its tenth clause then declaring in hortatory fashion: “That excessive bail ought not to be required, nor excessive fines imposed, nor cruel and unusual punishments inflicted.” The prohibitions against excessive bail and excessive fines and the final phrase—“nor cruel and unusual punishments inflicted”—were later …

How Experts View The Legal System's Use Of Scientific Evidence, Shari Seidman Diamond, Richard Lempert

Articles

Legal scholars and courts frequently write about how scientific evidence is vetted and presented in legal proceedings, but the views of experts themselves have received little attention. Our research aims to fill that gap. This paper reports some of what we learned from a series of surveys we conducted, beginning with a survey in 2016 of scientists who had been elected to membership in the American Academy of Arts and Sciences.3 Subsequent surveys were directed to subscribers of the journal Science who identified as scientists and engineers and to self-identified experts who advertised their availability as experts to lawyers or …

‘I Could Replicate The Situation Exactly The Same As I Do In Class’: Apprentice Lecturers Use Of A Learning Management System At An Irish University During And After Covid-19, Eleanor Attridge, Tom O'Mahony

Articles

While technology is playing a more critical role in learning, apprentice lecturers’ use of technology to support learning is under-researched. This qualitative study explores apprentice lecturers’ use and experience of a Learning Management System during and after COVID-19. Thematic analysis was used to make sense of the rich data, gathered using semi-structured interviews, from ten apprentice lecturers. The analysis revealed that technology use largely mirrored participants’ teacher-centric face-to-face methods. This approach did not sustain apprentice online engagement. Applying the theoretical framework, TPACK revealed that limited pedagogical expertise and, to a lesser extent, limited technological proficiency shaped participants’ approaches. Systemic constraints …

Deglobalization, Tax Competition, And The Potential Revival Of The Welfare State, Reuven S. Avi-Yonah, Doron Narotzki

Articles

Before 1980 the world was relatively closed. There were significant barriers to cross-border trade and investment in the form of tariffs and exchange controls. Martin Feldstein, former President Reagan’s chief economic adviser, coauthored an article in 1979 that showed that investment in the U.S. economy was about equal to U.S. savings, so the United States could manage without any foreign direct or portfolio investment.

Optimising Non-Cycloplegic Screening Strategies For Early Detection Of Pre-Myopia And Myopia In Young Children, Síofra Harrington, Michael Moore, James Loughman, Ian Flitcroft, Veronica O'Dwyer

Articles

Purpose: Early detection of myopia is essential to delay its onset and progression. Pre-myopia, defined by an inadequate hyperopic reserve, increases myopia risk in childhood. However, effective screening methods remain limited. This study aimed to develop practical non-cycloplegic screening methods for pre-myopia and myopia in 6- to 7-year-olds to support earlier interventions.

Methods: This cross-sectional study of 621 Irish schoolchildren (mean age: 7.12 ± 0.45 years; 51.8% boys) assessed uncorrected distance visual acuity (UDVA). Cycloplegic spherical equivalent refraction (SER) classified refractive status (myopia: SER ≤ −0.50D; pre-myopia: SER > −0.50 ≤ 0.75D). Pre- and post-cycloplegic SER were measured using the Welch …

Novel Corporate Governance Structures, Jennifer S. Fan, Xuan-Thao Nguyen

Articles

Artificial Intelligence (“AI”) startups have taken center stage, rapidly disrupting conventional industries at an unprecedented pace with their groundbreaking innovations. Hailed by many as the most significant technological advancement of our era, AI’s profound societal impact has garnered heightened public and governmental scrutiny. The spotlight has recently fallen on OpenAI, the creator of ChatGPT, which weathered a tumultuous period marked by the ouster and subsequent rehiring of CEO Sam Altman, a board reconfiguration, and Altman’s later return to the board. Concerns over AI safety were offered as the rationale for the tandem corporate governance structure of nonprofit and for-profit at …

Deleting Values May Either Increase Or Decrease Variance, David L. Farnsworth

Articles

The impact upon variance when a value is deleted is addressed. It is shown that the cutoff for the deleted value yielding an increase or a decrease in variance is approximately one standard deviation from the mean for a univariate random variable with equally distributed probability on a finite set of elements and for a univariate set of observations. The influence of truncation of the domain for such a discrete random variable and for observations is considered.

The Ai Input Class: Constitutional Urgency And Fair Licensing In Ai Copyright Class Actions, Xuan-Thao Nguyen, Elizabeth G. Porter

Articles

The humanities have long been under attack; now Big Tech is eating them for breakfast. Artificial Intelligence is undermining the cultural and constitutional values of human creativity; it is also threatening the livelihoods of the creative working class. Because neither Congress nor regulators can keep pace with AI’s pace of change, class actions have stepped into the breach. In the first wave of such litigation, authors and artists in courts on both coasts claim that AI companies violate intellectual property law when they “train” their systems on copyrighted works.

This Article analyzes what we call “input” AI claims—that is, proposed …

An Empirical Evaluation Of Communication Technologies And Quality Of Delivery Measurement In Networked Microgrids, Ruairí De Fréin, Yasin Emir Kutlu

Articles

Networked microgrids (NMG) are gaining popularity as an example of smartgrids (SG), where power networks are integrated with communication technologies. Communication technologies enable NMGs to be monitored and controlled via communication networks. However, ensuring that communication networks in NMGs satisfy quality of delivery (QoD) metrics such as the round trip time (RTT) of NMG control data is necessary. This paper addresses the communication network types and communication technologies used in NMGs. We present various NMG deployments to demonstrate real-life applicability in different contexts. We develop a real-time NMG testbed using real hardware such as Cisco 4331 Integrated Services Routers (ISR). …

Articles

In today’s ever-changing world, we are increasingly vulnerable to shocks and stresses that disrupt industry and society. Persistent threats from natural and manmade hazards require our communities and infrastructure to be resilient despite possible disruption. Creating robust infrastructures is founded on operational and physical standards to withstand and respond to threats such as environmental exposures, climate change, and informational security breaches. The significant U.S. investment in infrastructure projects through the Infrastructure Investment and Jobs Act has amplified the need for professionals in engineering and related fields who – in addition to technical knowledge - possess the necessary knowledge and skill …

Drivers Of Effective Laws For Automated Vehicles, William Hubbard

Articles

Hundreds of thousands of automated vehicles (AVs) are currently driving on America’s roads. The defining feature of AVs is that sophisticated technological systems control some or even all aspects of vehicle movement. Like any motor vehicle, AVs provide many benefits but also raise significant safety concerns. Indeed, people are already dying in collisions with AVs. Effective AV regulation is therefore critical.

This Article addresses an important—perhaps the most important— issue of AV regulation today. Recent empirical research has uncovered a shocking legal crisis: more than 40,000 conventional state laws are unclear or ineffective when applied to AVs. Fortunately, the vast …

Defining Demand - The Suitability Of Sensor-Based Demand-Controlled Ventilation Within Deep Energy Retrofit Dwellings, Seamus Harrington, Mark Mulville

Articles

This paper reviews a Sensor-Based Demand-Controlled Ventilation (SBDCV) system which seeks to provide fresh air for breathing and to dilute and exhaust pollutants and odours. Previous studies have demonstrated that the constant pressure system increases ventilation extract and inflow based on relative humidity levels and/or presence detection and works on the assumption that the level of ventilation provided is sufficient to control the concentration of all indoor air pollutants, including those that are not occupant generated. This paper presents the results obtained from monitoring the indoor air quality of eight dwellings that had undergone a fabric-first deep energy retrofit and …

Waste, Property, And Useless Things, Meredith Render

Articles

How should the law respond to intentionally useless objects that are constructed from scarce materials and thrust into an overcrowded world?

Approximately sixty million tons of electronic waste, or "e-waste" -for example, discarded iPhones, refrigerators, desktop computers -is produced each year. This annual pile of electronic rubbish represents sixty-two billion dollars' worth of tangible raw materials (such as gold and other scarce metals) that has been rendered useless. In addition to wasting raw materials, e-waste clogs our landfills, poisons the groundwater, and taxes our capacity to store it. Worst of all, much of this waste is intentionally created …

Regulating Hidden Ai Authorship, Jacob Noti-Victor

Articles

With the rapid emergence of high-quality generative artificial intelligence (“AI”), some have advocated for mandatory disclosure when the technology is used to generate new text, images, or video. But the precise harms posed by nontransparent uses of generative AI have not been fully explored. While the use of the technology to produce material that masquerades as factual (“deepfakes”) is clearly deceptive, this Article focuses on a more ambiguous area: the consumer’s interest in knowing whether works of art or entertainment were created using generative AI. In the markets for creative content—fine art, books, movies, television, music, and the like—producers have …

Flow Dynamics Of Agricultural Waste Nanofibers: Shear, Temperature, And Oscillatory Insights, Bilge N. Altay, Burak Aksoy, James Atkinson, Christopher Lewis, Carlos Diaz-Acosta, Raymond Francis

Articles

The rheology and fiber size of corn stover (CS) and cleaned cotton gin trash (CGT) cellulose nanofibers (CNFs) were studied including behaviors at both moderate and extremely high shear rates, to simulate industrial processes ranging from mixing and pumping to high-speed coating, printing, and extrusion. Particle size analyzer showed that 99% of CS fibers measured around 226 nm, while 85% of CGT fibers were approximately 143 nm. Both CS and CGT CNFs formed gel-like suspensions, and shear flow tests revealed that all samples exhibited shear-thinning behavior, allowing easy flow under shear forces. Gels with higher solid content (1%) demonstrated extended …

Quantifying The Role Of Active Listening And Reassurance In Virtual Health Coach Interactions, Ghulam Hussain, Brian Keegan, Robert Ross

Articles

Conversational Agents have the potential to support healthcare through coaching exercise routines, but are still lacking in demonstrating authentic social behaviours to support engagement. To this end, we present a series of experiments that we conducted in order to investigate how automated health care coaches can be more effective when their interaction style is tailored to demonstrate qualities associated with a good bedside manner, namely active listening and reassurance. To test this, we first developed a dataset of 135 dialogue excerpts from three distinct sources, i.e., original, handcrafted and LLMs, the latter two of which were tuned to demonstrate specific …

A Review Of Chemical Stabilisation Used To Enhance The Mechanical Properties Of Rammed Earth, David Thompson, Charles Augarde, Juan Pablo Osorio

Articles

Rammed earth is a sustainable construction method with a lower carbon footprint and embodied energy compared to traditional materials like steel and concrete. However, its lower mechanical properties when compared to these forms of construction make it vulnerable to seismic forces. This paper reviews the published literature on enhancing rammed earth's mechanical properties through both chemical stabilisation and fibre reinforcement, with a focus on reusing waste materials. The effectiveness of these techniques are highlighted by comparing experimental results with minimum specifications taken from relevant guidelines and standards for building rammed earth structures in seismic zones. These findings demonstrate that chemical …

A Comparison Study Of Senior And Junior Deck Officers’ Interpretations Of The International Regulations For The Prevention Of Collisions At Sea, Ian Heffernan, Tom O'Mahony

Articles

The International Regulations for the Prevention of Collisions at Sea (IRPCS) provide a comprehensive set of instructions for watchkeeping officers to follow and prevent collisions at sea. This study compares how six newly qualified deck officers and six Master Mariners, who were all trained at the same college, applied the IRPCS. Individual, semi-structured interviews were used to uncover how the 12 participants applied and interpreted the rules for three authentic scenarios. Phenomenography was used to capture the qualitatively different means by which participants interpreted the IRPCS. For basic collision avoidance situations, the results indicated little difference between the cohorts' ability …

Development Of The Navigation Guide Evidence-To-Decision Framework For Environmental Health: Version 1.0, Nicholas Chartres, Max T. Aung, Sustan L. Norris, Courtney Cooper, Lia A. Bero, Roger Chou, Devon C. Payne-Sturges, Wendy E. Wagner, Jessica W. Reyes, Lisa M. Askie, Daniel A. Axelrad, Deysi Flores Vigo, Jill E. Johnston, Juleen Lam, Keeve E. Nachman, Eva Rehfuess, Rachel Rothschild, Patrice Sutton, Lauren Zeise, Tracey J. Woodruff

Articles

Environmental exposures, including widespread industrial pollution, impact human health and are amplified in more highly exposed communities. Policy and regulatory frameworks for making decisions and recommendations on interventions to mitigate or prevent exposures tend to narrowly focus on exposure and some health-related data related to risks. Typically, such frameworks do not consider other factors, including essentiality, health equity, and distribution of benefits and costs. Further, decisions and recommendations lack transparency regarding how they were developed. We developed the Navigation Guide Evidence-to-Decision Framework for Environmental Health (E2DFEH) to provide a structured and transparent framework incorporating a range of scientific information and …

Tax In Law Schools, Michael Hatfield

Articles

At the 2023 Association of American Law Schools Tax Section meeting, professors discussed their impressions of a decline in the number of JD students studying tax. Their impressions were consistent with declines that have been documented in similar fields. Between 2011 and 2021, U.S. accounting programs saw an 18% drop in students, while new CPA candidates declined 39% from 2010 to 2022. In the United Kingdom, the number of law schools that teach tax has diminished by 43% since 2002. This Article examines tax education in 40 U.S. law schools, focusing on course offerings and enrollment trends from 2012 to …

Locating Consumer Financial Regulation, Nikita Aggarwal

Articles

Recent advances in data-driven technology in consumer financial markets, commonly referred to as "fintech," have resurfaced the question of whether and to what extent data, particularly consumers' personal data, should be a locus for regulatory intervention in these markets. While innovation in fintech and the accompanying increase in the processing of personal data offer to improve the functioning of consumer financial markets, like all advances in technology, they also come with costs and risks. In 2024, in a move that favored the regulation of personal financial data per se and many of the traditional features of personal data protection regulation, …

Articles

This study seeks to understand the effects on researchers’ work at a large research university in the wake of the university library’s shift from a near-comprehensive journals package with a single, large publisher to a selective list of individual journal subscriptions. Analyzing historical journal usage, along with turnaway and interlibrary loan trends from the years following the changes, the authors made use of structured interviews with local researchers to bring context and meaning to the quantitative data. The interviews highlighted researchers’ strategies for gaining access to literature in their fields to which the library does not subscribe, and revealed assumptions …

Standardization And Accuracy Of Race And Ethnicity Data: Equity Implications For Medical Ai, Alexandra Tsalidis, Lakshmi Bharadwaj, Francis X. Shen

Articles

The rapid integration of artificial intelligence (AI) into healthcare has raised many concerns about race bias in AI models. Yet, overlooked in this dialogue is the lack of quality control for the accuracy of patient race and ethnicity (r/e) data in electronic health records (EHR). This article critically examines the factors driving inaccurate and unrepresentative r/e datasets. These include conceptual uncertainties about how to categorize races and ethnicity, shortcomings in data collection practices, EHR standards, and the misclassification of patients’ race or ethnicity. To address these challenges, we propose a two-pronged action plan. First, we present a set of best …

Gene therapy is a rapidly developing field, finally yielding clinical benefits. Genetic engineering of organs for transplantation may soon be an option, thanks to convergence with another breakthrough technology, ex vivo machine perfusion (EVMP). EVMP allows access to the functioning organ for genetic manipulation prior to transplant. EVMP has the potential to enhance genetic engineering efficiency, improve graft survival, and reduce posttransplant complications. This will enable genetic modifications with a vast variety of applications, while raising questions on the ethics and regulation of this emerging technology. This review provides an in-depth discussion of current methodologies for delivering genetic vectors to …

Fairness In Contract Law: An Impossibility Theorem?, Francesco Parisi, Brian H. Bix

Articles

Scholars have long debated whether contract law should prioritize maximizing efficiency and social welfare or, instead, prioritize justice, fairness and other deontological values. The debate is partly prescriptive (what should we try to do with contract law rules) and partly conceptual (how should we understand contract law). This article surveys central positions in this debate, distinguishing between the corrective and redistributive functions of contract law and between doing justice between the parties and more systemic effects. It highlights an impossibility theorem that underscores the self-defeating nature of redistributive policies in price-based contractual relationships, using a numerical example and two policy …
