Does Generative Ai Facilitate Investor Trading? Early Evidence From Chatgpt Outages, Qiang Cheng, Pengkai Lin, Yue Zhao

Research Collection School Of Accountancy

In this paper, we use ChatGPT outages to provide early evidence on whether investors rely on generative artificial intelligence (GenAI) to perform professional tasks and the associated impact on stock price informativeness. We document a significant decline in stock trading volume during ChatGPT outages. The effect is stronger for firms with corporate news released immediately before or during the outages and for firms with higher ownership held by transient institutional investors. We then document declines in short-run price impact and return variance during the outage periods, consistent with reduced informed trading. Lastly, we document a positive effect of GenAI-assisted trading …

Discussion Of "Csr And Negative Corporate Events: The Moderating Role Of Managerial Overconfidence", Hye Sun Chang

Research Collection School Of Accountancy

Corporate social responsibility (CSR) refers to the notion that firms are accountable not only to shareholders but also to a broader set of stakeholders including customers, employees, creditors, and the communities in which they operate. Although CSR has long been part of corporate discourse, its prominence has grown with the rise of environmental, social, and governance (ESG) concerns. Today’s consumers and stakeholders are increasingly attentive to issues such as climate change, economic inequality, labor rights, and social justice, prompting firms to align their strategies with evolving societal expectations. Building on this increasingly salient backdrop, Chu et al. (2026), hereafter CCT, …

Chain Of Strategy Optimization Makes Large Language Models Better Emotional Supporter, Weixiang Zhao, Xingyu Sui, Xinyang Han, Yang Deng, Yulin Hu, Jiahe Guo, Libo Qin, Qianyun Du, Shijin Wang, Yanyan Zhao, Bing Qin, Ting Liu

Research Collection School Of Computing and Information Systems

The growing emotional stress in modern society has increased the demand for Emotional Support Conversations (ESC). While Large Language Models (LLMs) show promise for ESC, they face two key challenges: (1) low strategy selection accuracy, and (2) preference bias, limiting their adaptability to users’ emotional needs. Existing supervised fine-tuning (SFT) struggles to address these issues, as it rigidly trains models on single gold-standard responses without modeling nuanced strategy trade-offs. To overcome these limitations, we propose a novel two-stage framework that optimizes strategy selection preferences at each dialogue turn. We first leverage Monte Carlo Tree Search to construct ESC-Pro, a high-quality …

Security Modelling For Cyber-Physical Systems: A Systematic Literature Review, Shao Fei Huang, Christopher M. Poskitt, Lwin Khin Shar

Research Collection School Of Computing and Information Systems

Cyber-physical systems are at the intersection of digital technology and engineering domains, rendering them high-value targets of sophisticated and well-funded cybersecurity threat actors. Prominent cybersecurity attacks on CPS have brought attention to the vulnerability of these systems and the inherent weaknesses of critical infrastructure reliant on them. Security modelling for CPS is an important mechanism to systematically identify and assess vulnerabilities, threats, and risks throughout system life cycles, and to ultimately ensure system resilience, safety, and reliability. This survey delves into state-of-the-art research on CPS security modelling, encompassing both threat and attack modelling. While these terms are sometimes used interchangeably, …

Disc: Decentralized Identity System With Self-Sovereign Credential Aggregation, Yang Yang, Wai Keung Ching, Minming Huang, Supachate Innet, Guomin Yang, Hwee Hwa Pang, Robert H. Deng

Research Collection School Of Computing and Information Systems

The evolution of decentralized identity (DID) and self-sovereign identity (SSI) frameworks, as endorsed by W3C Verifiable Credentials (VC) and eIDAS 2.0, underscores the need for secure, efficient, and privacy-preserving credential management. However, existing credential systems often depend on centralized issuers, lack efficient aggregation mechanisms, or fail to ensure unlinkability across authentication sessions. To address these challenges, we propose DISC (Decentralized Identity System with Self-Sovereign Credential Aggregation), a novel credential system that enables multi-authority credential issuance, user-controlled credential aggregation, and unlinkable authentication. DISC allows users to aggregate credentials from multiple issuers while maintaining constant-size authentication tokens and supporting batch verification for …

Towards Goal-Oriented Intelligent Tutoring Systems In Online Education, Yang Deng, Zifeng Ren, An Zhang, Tat-Seng Chua

Research Collection School Of Computing and Information Systems

Interactive Intelligent Tutoring Systems (ITSs) enhance the learning experience in online education byfostering effective learning through interactive problem-solving. However, many current ITS models do notfully incorporate proactive engagement strategies that optimize educational resources through thoughtfulplanning and assessment. In this work, we propose a novel and practical task of Goal-oriented IntelligentTutoring Systems (GITS), designed to help students achieve proficiency in specific concepts through a tailoredsequence of exercises and evaluations. We introduce a novel graph-based reinforcement learning framework,named Planning-Assessment-Interaction (PAI), to tackle the challenges of goal-oriented policy learningwithin GITS. This framework utilizes cognitive structure information to refine state representation andguide the selection …

Micronuclei As A Marker Of Genotoxicity In An Urban Songbird., Elise Mittlestat

College of Arts & Sciences Senior Theses

A rise in industry and vehicle emissions in the last 20 years has led to an increase in exposure to air pollution. Air pollution has been identified as a major threat to both human and animal health and it has been linked to elevated oxidative stress. One of the most severe consequences of oxidative stress is genotoxic damage. Birds have been identified as promising sentinels for human health, but the effects of air pollution on genotoxicity in birds is understudied. In this study, I evaluated the association between air pollution and markers of genotoxicity in American Robins (Turdus migratorius) to …

Active Galactic Nuclie In Diverse Galactic Environments, Divya A. Patel

College of Arts & Sciences Senior Theses

We examine how the presence of active galactic nuclei (AGN) correlates with location in large-scale cosmic structures using the Galaxy and Mass Assembly (GAMA) survey across the G09, G12, and G15 fields. Our sample contains 18,927, 9,273, and 1,148 galaxies {with} highly dense filaments, moderately dense tendrils, and highly underdense voids, respectively. AGN galaxies were identified using Baldwin-Phillips-Telverich (BPT) diagnostic diagrams based on [NII], [SII], and [OI]. We compare AGN fractions in filament, tendril, and void regions, and as a function of distance from the nearest filament centerline. Our results reveal a mild excess in filament compared to void, when …

Odor Concentration Matters: How Odor Concentration Guides Consummatory Behavior And Formation Of Odor-Taste Associations In Rats, Dinna N. Ferreira

College of Arts & Sciences Senior Theses

Taste concentration is a key determinant of palatability. For example, higher concentrations of sucrose, a sweet taste, are typically preferred to lower ones, whereas the opposite is true for citric acid, a sour taste. Yet taste is not the only determinant of food preference. Flavor arises from the integration of taste and olfactory cues, and repeated exposure to odor-taste combinations can lead odors to acquire the hedonic value of their associated taste. However, the contribution of odor concentration, independent of taste, in guiding consummatory behavior is not well understood.

To address this, we conducted two experiments using a two-bottle brief-access …

Legal Realignment, Richard Re

University of Chicago Law Review

The United States is undergoing a legal realignment, in that salient legal views recently associated with the right are now being espoused by the left, and vice versa. The clearest example involves Chevron deference: a doctrine once championed by conservatives like Justice Antonin Scalia has now been overruled in Loper Bright v. Raimondo—over dissenting votes by all three of the Court’s liberals. Similar points can be made about standing, stare decisis, textualism, positivism, and more. The basic reason for this transformation is straightforward: legal ideologies in power favor discretion, whereas those out of power favor constraint. Conservatives now firmly control …

Purpose

The purpose of this study was to explore different brain network connectomic relationships subserving hand dexterity in patients with contrast-enhancing brain tumors during task and resting states.

Method

We measured hand dexterity, resting state functional connectivity, and task-based functional connectivity in 21 participants with newly diagnosed brain tumors. Hand dexterity was measured using the 9-hole peg test (9HPT), and patient-reported outcomes were assessed with the Duroz Hand Index (DHI).

Findings

We discovered the following: (1) The inability to complete dexterous tasks is most associated with low somatomotor-basal ganglia network connectivity during rest but high somatomotor-basal ganglia network connectivity during …

The Irrelevance Of “Peak Fame” On Celebrity Candidate Success, Richard T. Longoria, Dana Reyes

Political Science Faculty Publications

Objective

Does it matter “when” a celebrity runs for office? The political scientists who study celebrity candidates need to consider an important insight from communications and media scholars. Fame is a time-dependent variable. Someone who was famous 40 years ago may no longer be widely known today.

Methods

A list of celebrity political candidates who ran for office in the United States between 1865 and 2022 was created to measure campaign success.

Results

In terms of winning an election, it does not matter whether a celebrity candidate runs at the peak of their fame or waits until decades later. What …

Consumers Stabilize Grassland Ecosystem Functions By Destabilizing Belowground Communities Under Abiotic Stress, Jane M. Lucas, Michelle L. Budny, Nathan P. Lemoine

Biological Sciences Faculty Research and Publications

Consumers play a critical role in mediating plant and ecosystem responses to abiotic stress, yet their influence on belowground processes under changing environmental conditions remains underexplored. Insect consumers are vital components of grassland ecosystems that can shape ecosystem function and stability by mitigating how plant and microbial communities respond to abiotic stress, like drought. This study investigates how small-bodied consumers influence the magnitude and stability of grassland belowground functions across gradients of abiotic stress. We conducted a fully factorial field experiment manipulating consumer presence and induced drought over a growing season. Our results reveal that the presence of consumers stabilizes …

Comparative Fire Hazards Of Lithium-Ion Battery Chemistries: Linking Thermal Behavior, Gas Toxicity, And State-Of-Charge To Composite Risk Profiles, Aamir Iqbal, Ashish Kakoria, Syed Talha Riaz, Jingmin Xu, Robert Illango Pushparaj, Guang Xu

Mining Engineering Faculty Research & Creative Works

Lithium-ion batteries (LIB) are widely used in electric vehicles (EVs) for their high energy density. However, their fire safety causes concerns because of the toxic gases emission and the challenge to extinguish. The type and quantity of toxic gases released during battery fires remain among the least studied hazards, with limited data available despite their serious health risks. This study examines the thermal and gaseous emission behavior of LIB cells after thermal runaway (TR). Five cell types, Lithium Iron Phosphate (LFP), Lithium Titanate (LTO), and three Lithium Nickel Manganese Cobalt oxide (NMC). The three NMC variants share the same base …

Energy-Harvesting Concurrent Lora Mesh With Timing Offsets For Underground Mine Emergency Communications, Hilary Kelechi Anabi, Samuel Frimpong, Sanjay Madria

Mining Engineering Faculty Research & Creative Works

Underground mine emergencies destroy communication infrastructure when situational awareness is most critical. Current systems rely on centralized network infrastructure, which fails during emergencies when miners are trapped and require rescue coordination. This paper proposes an energy-harvesting LoRa mesh network that addresses self-powered operation, interference management, and adaptive physical layer optimization under severe underground propagation conditions. A dual-antenna architecture separates RF energy harvesting (860 MHz) from LoRa communication (915 MHz), enabling continuous operation with supercapacitor storage. The core contribution is a decentralized scheduler that derives optimal timing offsets by modeling concurrent transmissions as a Poisson collision process, exploiting LoRa's capture effect …

Fisheries Research Report No. 355: Recreational Fishing For Western Rock Lobster In 2024/25: Estimates Of Participation, Effort And Catch, Claire B. Smallwood, Karina L. Ryan, Alissa Tate

Fisheries Research Reports

The Western Rock Lobster (WRL) (Panulirus cygnus) is the most commonly caught Rock Lobster (RL) species in Australia. Catches from the commercial and recreational sectors are required to determine and monitor Total Allowable Commercial Catch (TACC), Total Allowable Recreational Catch (TARC) and the proportion of Allowable Harvest Level (AHL) achieved. The TARC is evaluated annually based on a 5-year average.

Data for the recreational sector are obtained using phone-recall surveys to provide annual estimates of participation, fishing effort and retained catch (by numbers) from recreational fishers who hold a RL licence. Average weight, obtained from boat ramp surveys, are used …

Small For Gestational Age Subgroups Have Differential Morbidity, Growth, And Neurodevelopment At Age 2: The Interbio-21st Newborn Study, Aris Papageorghiou, María Restrepo-Méndez, Rose Mcgready, Fernando Barros, Francois Nosten, Shama Munim, R. Ochieng, Rachel Craik, Hellen Barsosio, James Berkley

Paediatrics and Child Health, East Africa

BACKGROUND: Small for gestational age is a complex perinatal syndrome associated with increased neonatal morbidity, mortality, and impaired childhood growth and neurodevelopment. Current classifications rely primarily on birthweight, which does not capture the heterogeneity of the condition nor predict long-term health outcomes. Here we aim to identify and characterize distinct small for gestational age subgroups and assess their neonatal and early childhood health trajectories.

OBJECTIVE: To refine the classification of small for gestational age by identifying subgroups based on maternal, fetal, and environmental factors and evaluating their associations with neonatal morbidity, growth, and neurodevelopment at age 2.

Crop, Soil and Environmental Sciences Faculty Publications and Presentations

Frass-the main by-product of insect rearing for animal feed-is emerging as a promising soil amendment and plant growth promoter. However, basic agronomic information is lacking and prevents frass' widespread use as a biofertilizer. This study assessed impacts of black soldier fly (Hermetia illucens L. [Diptera: Stratiomyidae]) frass on soil fertility, crop growth, and quality compared to poultry litter (PL). Irrigated and non-irrigated soybean (Glycine max L. Merr.) and non-irrigated switchgrass (Panicum virgatum L.) plots received either PL (5.6 Mg ha(-1)), low frass rate (LF; 5.6 Mg ha(-1)), high frass rate (HF; 11.2 Mg ha(-1)), besides the unamended control (CT). In …

A pilot program aimed to a) develop and disseminate educational materials and supplies and b) perform in-home childcare facility assessments to increase knowledge regarding lead and pesticide safety, provide education on the health impacts of elevated blood lead levels, and reduce exposure risks in these settings. The program was implemented in St. Louis, Missouri. From outreach and education efforts to interactive feedback, this article shares important lessons learned and highlights educational gaps that …

Intraoperative Electrical Stimulation Can Identify Potential Ulnar Nerve Injury From Crossed Pinning Of A Supracondylar Humerus Fracture., Lucas A. Georger, Mckenna C. Noe, Richard M. Schwend

Manuscripts, Articles, Book Chapters and Other Papers

Treatment of Gartland type III supracondylar fractures using reduction and crossed Kirschner wire fixation is considered the most stable method; however, there is a risk of iatrogenic ulnar nerve injury during medial pin placement. We describe a technique for intraoperative detection of such nerve injury.An inexpensive disposable nerve stimulator is set at 2 mA and applied directly to the Kirschner wires after placement, alerting the surgeon intraoperatively if a wire contacts the ulnar nerve. A positive response involves any finger motion with Kirschner wire stimulation. We recommend this novel method of intraoperative Kirschner wire stimulation using an inexpensive disposable nerve …

Ceo-Board Political Alignment And Firm Performance: An Examination Of Declines From Homogeneity That Are Mitigated By Ceo Psychological Traits, James Grabowski, Christina Robichaud, David B. Wangrow

Management Faculty Research and Publications

As people group themselves by their political ideologies, ideological alignment is likely to occur in workgroups—including boards of directors. While some research highlights positive outcomes from shared group characteristics, homogeneity can also hinder decision-making due to fewer perspectives being considered, limited sharing of non-conforming information, and narrowed problem solving. Building from prior research, we contend that substantial political alignment between a CEO and board members aligns them toward a common cognition, which fosters negative effects associated with homogeneity and subsequently reduces firm performance. We further contend that these performance reductions can be mitigated by psychological traits associated with managerial discretion. …

High-Energy And On The Move: Exploring The Kinematic And X-Ray Properties Of Young Stars Near Earth With Gaia, Chandra, And Erosita, Attila Vincent Varga

Theses

Young stars in the solar neighborhood provide a unique and insightful window into stellar evolution during the first few hundred million years after formation. Leveraging archival photometric and astrometric data from ESA’s Gaia Space Astrometry mission, as well as photometric data from NASA (2MASS and WISE) archives, I have identified over 50 new members of the nearby (D ∼ 100 pc), 3–8 Myr-old Epsilon Cha association (ECA), including six new proto-brown dwarf candidates. By modeling the kinematics and photospheric properties of both newly identified and previously known members of the ECA and Lower Centaurus Crux (LCC), I further established the …
