Confronting Catastrophic Risk: The International Obligation To Regulate Artificial Intelligence, Bryan Druzin, Anatole Boute, Michael Ramsden

Michigan Journal of International Law

While artificial intelligence (“AI”) holds enormous promise, many experts in the field are warning that there is a non-trivial chance that the development of AI poses an existential threat to humanity. Existing regulatory initiatives do not address this threat but instead merely focus on discrete AI-related risks such as consumer safety, cybersecurity, data protection, and privacy. In the absence of regulatory action to address the possible risk of human extinction by AI, the question arises: What obligations, if any, does public international law impose on states to regulate its development?

At present there is no scientific consensus as to the …

Moss-Magee Rehabilitation Papers

Tulving characterized semantic memory as a vast repository of meaning that underlies language and many other cognitive processes. This perspective on lexical and conceptual knowledge galvanized a new era of research undertaken by numerous fields, each with their own idiosyncratic methods and terminology. For example, "concept" has different meanings in philosophy, linguistics, and psychology. As such, many fundamental constructs used to delineate semantic theories remain underspecified and/or opaque. Weak construct specificity is among the leading causes of the replication crisis now facing psychology and related fields. Term ambiguity hinders cross-disciplinary communication, falsifiability, and incremental theory-building. Numerous cognitive subdisciplines (e.g., vision, …

The research reviews relevant papers on recent SD model applications in urban sustainability since 2018, categorizing them based on nine key indicators. Among the reviewed papers, …

Nanoparticles Of Iridium And Other Platinum Group Elements Identified In Chicxulub Asteroid Impact Spherules – Implications For Impact Winter And Profound Climate Change, Vivi Vajda, Susan Nehzati, Gavin Kenny, Hermann D. Bermúdez, Ashley Krüger, Alexander Björling, Adriana Ocampo, Ying Cui, Kajsa G.V. Sigfridsson Clauss

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

The Chicxulub asteroid that ended the Cretaceous Era ∼66.05 million years ago caused a prolonged time of global darkness – the impact winter – leading to mass extinctions. Elements from the asteroid, including the platinum group elements (PGEs) osmium, iridium and platinum are known from the globally distributed boundary clay but their carrier elements have so far been unknown. We identify, for the first time in detail, the presence of these PGEs within Chicxulub impact spherules and importantly, we identify their carrier elements. We show through synchrotron Nano-XRF how these PGEs occur in nanostructures as un-ordered cube- and/or needle-like crystals …

Literary Executor Of The Estate Of Christopher Dawson, Julian Scott

Comparative Civilizations Review

Christopher Dawson was a historian of religion and culture who wrote and lectured in England and America between the 1920s and his death in 1970. The author of this review, Dawson’s grandson and literary executor, argues not only that Dawson is very interesting to read as a historian, but also that many of his insights and proposals — such as his writing on European unity, nationalism, the consequences of a secularized culture and the conflict between humane individualism and state totalitarianism — remain highly relevant today. This article highlights some of Dawson’s most interesting and insightful ideas and aims to …

Luminescence Dating Of Hydrothermal Explosions In The Yellowstone Plateau Volcanic Field, Karissa Cordero, Nathan D. Brown, Lauren N. Harrison, Shaul Hurwitz

Earth & Environmental Sciences Datasets - Archive

Hydrothermal explosions are a significant geological hazard in some active volcanic systems; however, the timing and triggering mechanisms of these explosions are poorly constrained. This study applies luminescence dating techniques to hydrothermal explosion deposits in the Yellowstone Plateau volcanic field to constrain explosion chronologies and evaluate potential triggering mechanisms. We tested four luminescence dating techniques: K-feldspar post-infrared infrared stimulated luminescence (pIRIR225), quartz blue light optically stimulated luminescence (BLOSL), quartz blue thermoluminescence (BTL), and quartz red thermoluminescence (RTL). The pIRIR225 and RTL protocols produce consistent age estimates that agree with independent radiocarbon ages and with the timing of the Pinedale deglaciation. …

Males Differ More Between Developmental Stages Than Females, And Plasticity To Light Is Stage-Dependent In The Tropical Plant Marchantia Inflexa, Jonathan D. Moore, D. Nicholas Mcletchie

Biology Faculty Publications

Plants have evolved strategies to maintain photosynthesis and mitigate tissue-damaging high light. In some dioecious seed plants, these strategies are sexually dimorphic and are linked to spatial segregation of the sexes (SSS) along light gradients. In vascular tissue-free plants (bryophytes) with separate sexes, SSS is common, but how light gradients, sexual dimorphisms, and SSS correlate is not well understood. To test if sexual dimorphisms in vegetative or sexual stages lead to light-associated SSS in bryophytes, we used Marchantia inflexa whose males occupy a wider range of light conditions, including higher light conditions, than females. We also tested if changes in …

Orbifolds And Minimal Modular Extensions, Chongying Dong, Siu Hung Ng, Li Ren

Faculty Publications

Let V be a simple vertex operator algebra and G a finite automorphism group of V such that V^G is regular, and the conformal weight of any irreducible g-twisted V-module N for g∈G is nonnegative and is zero if and only if N=V. It is established that if V is holomorphic, then the V^G-module category CV^G is a minimal modular extension of E=Rep(G), and is equivalent to the Drinfeld center Z(VecG^α) as modular tensor categories for some α∈H³(G,S¹) with a canonical embedding of E. Moreover, the collection Mv(E) of equivalence …

Refining A Chain Theorem From Matroids To Internally 4-Connected Graphs, Chanun Lewchalermvongs, Guoli Ding

Faculty Publications

Graph theory and matroid theory are interconnected with matroids providing a way to generalize and analyze the structural and independence properties within graphs. Chain theorems, vital tools in both matroid and graph theory, enable the analysis of matroid structures associated with graphs. In a significant contribution, Chun, Mayhew, and Oxley [2] established a chain theorem for internally 4-connected binary matroids, clarifying the operations involved. Our research builds upon this by specifying the matroid result to internally 4-connected graphs. The primary goal of our research is to refine this chain theorem for matroids into a chain theorem for internally 4-connected graphs, …

Potential Effects Of Statistical Complexity Measure In Improving The Fault Diagnosis Performance Under Speed Fluctuations, S. Sowmya, M. Saimurugan, N. Kannan, Immanuel A. Edinbarough

Informatics and Engineering Systems Faculty Publications

Many research studies are performed in extracting non-stationary signal properties such as instantaneous frequency (IF) and envelope to diagnose machinery faults under time-varying speed conditions. But accurate IF extraction is difficult from such complex fluctuating signals to identify the faults efficiently. Therefore, this paper proposes the Statistical Complexity Measure (SCM) as a feature that evaluates the randomness and complexity without any additional requirement, providing an outstanding result in multi-component fault detection under speed fluctuations. Primarily, the influence of SCM is proved by ranking the features with the help of the Random Forest (RF) algorithm. The fault classification of individual signal …

Zombie-Auras: Genai And Hybrid Text Production, Joshua Nieubuurt

English Faculty Publications

This paper explores the iterative evolutions of textual production and their impact on the “aura” of texts, as conceptualized by Walter Benjamin. The study identifies three key phases of textual production: the natural, the mechanized, and the digitized, each progressively displacing the “cult value” of texts. This cult value is lost through increased ease of creation, reproduction, dissemination, and dislocation of creators and audiences in time and space. The advent of Generative AI (GenAI) marks the latest evolution, transforming the “aura” into a memetic “zombie” form—familiar yet opaque, evoking both the sublime and fear. By examining Benjamin’s notion of “aura” …

When College Is Not Working Out: Obstacles To Community College Completion, Elisabeth Lackner

Dissertations, Theses, and Capstone Projects

My dissertation investigates what contributes to low community college completion rates, what college interventions may be working to support students, what are the experiences of the students, and how did the COVID-19 pandemic impact these dynamics. I am guided by the assumption that multi-dimensional inequalities including low level of social capital constitute a cumulative disadvantage for many students to be able to persist and to graduate. The dissertation includes quantitative and qualitative data types measuring inequalities outside and inside of college with two large student record data sets from one minority-serving open-access public community college and data from a student …

Constructing A Parameterized Stimuli Space Suitable To Induce Controlled Changes In Human And Machine Perceptual Systems, Andrew Frankel

Dissertations, Theses, and Capstone Projects

Traditional computer vision applications focus on objective tasks, such as object detection, classification, or segmentation. Much of human experience is inherently subjective, such as our personal response to artwork. Individualized experiences are challenging to replicate in a controlled laboratory environment, as those experiences depend on the unique history and internal models of the observer. This work presents a technique to construct a 2-dimensional parameterized stimuli space suitable to induce controlled changes in the perceptual systems of both human and machine observers. Our contributions are threefold:

1. Using a balanced dataset of 8,800 fine art images spanning 11 art movements and 88 …

Development Of Soil Survey Methods For Urban Areas, Kohinoor Begum

Dissertations, Theses, and Capstone Projects

Urban soils are the foundation of urban ecosystems and play a vital role in long-term urban sustainability and resiliency. Accurate soil surveys of urban areas should be done at higher resolution since extensive human activities often result in urban soil being highly disturbed and spatially variable. Besides heterogeneity, one of the unique and challenging aspects of urban soil is the nature and properties of its organic carbon with a significant percentage of black carbon (a particulate product of incomplete combustion), which is less biologically active. Thus, in order to determine the ability of a soil to support biological activity and …

A Computational Analysis Of The Effect Of Hard Choices On The Individuation Of Values, Norberto M. Grzywacz

Psychology: Faculty Publications and Other Works

Background/Objectives: Experimental studies show that when an individual makes choices, they affect future decisions. Future choices tend to be consistent with past ones. This tendency matters in the context of ambivalent situations because they may not lead to clear choices, often leading people to make “arbitrary” decisions. Thus, because of choice consistency with the past, people’s decision-making values diverge. Thus, hard choices may contribute to the individuation of values. Methods: Here, we develop a Bayesian framework for the effects of cognitive choice consistency on decision-making. This framework thus extends earlier cognitive-science Bayesian theories, which focus on other tasks, such as …
