High-Stakes Exams Inflate A Gender Gap And Contribute To Systematic Grading Errors In One Introductory Physics Series, David J. Webb, Cassandra Paul

Faculty Research, Scholarly, and Creative Activity

Previous research has suggested that changing the percentage of the course grade associated with exam grades in science, technology, engineering, and mathematics courses can change the gender gap in the course. It has also been shown that high-stakes assessments yield the lowest (relative) scores for female students. Previous research by the authors has shown that implementing retake exams can eliminate the gender gap in introductory physics courses. This paper explores several different hypotheses for why retake exams are associated with a zeroed gender gap. Two independent measurements comparing exams with different stakes are used in support of the argument that …

Algorithmic Collusion Among Ev Charging Stations With Independent Reinforcement Learning Agents, Yulin Zeng, Yiheng Zhao, Yuanliang Li, Yefeng Yuan, Jie Gao, Hepeng Li, Xiao'ou Yang, Hohyun Lee, Yuhong Liu, Jun Yan

Faculty Research, Scholarly, and Creative Activity

Recent advancements in reinforcement learning (RL) have significantly enhanced the autonomous decision-making capabilities of energy systems. In the realm of electric vehicle (EV) charging stations, operators aim to autonomously learn optimal pricing strategies based on local observations and user behavior. Traditional multi-agent reinforcement learning (MARL) approaches often assume cooperative settings with reward sharing or communication, real-world EV charging infrastructures are typically decentralized and competitive. This paper investigates the potential for tacit collusion in such realistic, non-cooperative environments. By leveraging decentralized MARL, we show that independently trained agents can still exhibit emergent collusive behaviors. Our findings highlight a critical need for …

Phase Transitions In An Ising Model Of Agent Expectations In Financial Markets: Analytics And Numerical Results In One And Two-Dimensional Network Topologies, Marko Raseta, Steven D. Silver, Alina Bazarova

Faculty Research, Scholarly, and Creative Activity

We cite correspondences between dynamics in competitive markets and information theory in the objective of recovering signal from noisy information sequences. In financial markets, this objective has been examined as recovering signal on phase transitions between ordered and disordered states of agents in the market. These transitions have been indicated to denote critical points in time series of market price. Although there is a noteworthy background in information theory in the study of the dynamics of the Ising model in this manuscript, we pursue a different modeling approach. Whereas phase transitions in a multicomponent model of market states have previously …

On The Road To A Better Life? Rural Road And Economic Development In Albania, Santosh Gautam, Ermal Llirjani, Patralekha Ukil

Faculty Research, Scholarly, and Creative Activity

This study evaluates the impact of investment in rural roads on household welfare in Albania using a difference-in-differences method. We find that treated households experienced a 35-percentage point increase in the road quality and reduced travel times to the nearest motorable roads. Land and housing values rose significantly, and household heads were less likely to be unemployed, with a shift toward self-employment. While household income did not change significantly, consumption—particularly on non-food items—increased. These findings highlight the welfare-enhancing effects of improved connectivity and suggest that rural infrastructure investments can promote local economic activity. Policymakers should consider pairing road upgrades with …

Cosmopolitan Spirits: Islam And The Experimental Cosmologies Of Egypt's Spiritualist Movement, 1947–1960, Arthur Shiwa Zárate

Faculty Research, Scholarly, and Creative Activity

This article considers the history of Egypt’s mid-twentieth-century Spiritualist movement through an examination of its periodical, a monthly Arabic magazine called Alam al-Ruh (The World of the Spirit) (1947–1960). As it shows, Egyptian Spiritualists defended and promoted their project by crafting an experimental cosmology, one that blended claims about empirical verification with elements of Islamic and Spiritualist cosmologies. It further shows how this combination of scientism and cosmology reflects a core dynamic within the history of scientific exploration in the Islamic world. Like spiritual seekers and occult practitioners in Muslim societies elsewhere, Egyptian Spiritualists positioned their project as one of …

Salmon Rushdie’S Frontier Pedagogy: Notes On Two Episodes In “Step Across This Line", Narayana Chandran Kizhakkethil

Asian American Literature: Discourses & Pedagogies

In the Indian multilingual classrooms teachers often discover certain details about the political semantics of the English texts they teach. When that happens, the language means much more to non-English readers who happily realize that English grants them a little more freedom to convey meanings to them than it does a monolingual readership. My example here is Salman Rushdie’s Tanner Lectures in Human Values called “Step Across This Line.” While his immediate context is the 9/11 tragedy and the politically prudent ways the US might cope with its aftermath, he returns time and again to those who brave borders, face …

Without Them, There Is No You: The Role Of Personal Choice And History In Resisting Political Control, Heidi Turner

Asian American Literature: Discourses & Pedagogies

In 2011, Korean-American journalist Suki Kim went undercover as an English teacher at the Pyongyang University of Science and Technology, working to teach her students while simultaneously recording everything she could about the workings of the Democratic People’s Republic of Korea (DPRK). In 2014, her book Without You, There is No Us was published as a memoir, in part due to the inclusion of personal details considered less relevant to the story, thereby undercutting her journalistic credentials.

Here, using C. S. Lewis’s The Abolition of Man as a theoretical framework for understanding oppressive regimes and the ways that they control …

Transpacific Rhizomatic Migration In Kyoung H. Park’S Mina: Settler Desire And Identity Formation In Korean-Latin American Literature In The U.S., Chase Kim

Asian American Literature: Discourses & Pedagogies

The Korean diaspora to the United States is a phenomenon that has long been analyzed for its sociocultural, political, and economic implications. However, generally ignored by scholarship of frameworks such as the transpacific is Korean-Latin American remigration to the United States. Korean migration to Latin America and this group’s subsequent migration to the US was motivated largely by economic factors such as the availability of Latin American agricultural labor in the mid-1960s and the growth of Korean-American professional communities during the 1980s. Situating this migration in a transpacific framework improves our understanding of settler colonial desire and identity formation. I …

Robust Hashing For Improved Cnn Performance In Image-Based Malware Detection, Sanket Shekhar Kulkarni, Fabio Di Troia

Faculty Research, Scholarly, and Creative Activity

This paper presents a comparative study on the impact of robust hashing in enhancing image-based malware classification. While Convolutional Neural Networks (CNNs) have shown promise when working with image-based malware samples, their performance degrades significantly when obfuscation techniques are taken into consideration to hamper the malware classification or detection. To address this, we apply a robust hashing technique that generates invariant visual representations of malware samples, enabling improved generalization under obfuscation implemented as image salting. Using a custom obfuscation method to simulate polymorphic variants, we evaluate MobileNet, ResNet, and DenseNet architectures across five salting conditions (0% to 40%). The results …
