Mitigation Of Algorithmic Bias To Improve Ai Fairness, Kathy Wang

Cybersecurity Undergraduate Research Showcase

As artificial intelligence continues to evolve rapidly with emerging innovations, mass-scale digitization could be disrupted due to unfair algorithms with historically biased data. With the rising concerns of algorithmic bias, detecting biases is essential in mitigating and implementing an algorithm that promotes inclusive representation. The spread of ubiquitous artificial intelligence means that improving modeling robustness is at its most crucial point. This paper examines the omnipotence of artificial intelligence and its resulting bias, examples of AI bias in different groups, and a potential framework and mitigation strategies to improve AI fairness and remove AI bias from modeling techniques.

The Dsa Toolkit Shines Light Into Dark And Stormy Archives, Shawn Morgan Jones, Himarsha R. Jayanetti, Alex Osborne, Paul Koerbin, Klein Martin, Michele C. Weigle, Michael L. Nelson

Computer Science Faculty Publications

Web archive collections are created with a particular purpose in mind. A curator selects seeds, or original resources, which are then captured by an archiving system and stored as archived web pages, or mementos. The systems that build web archive collections are often configured to revisit the same original resource multiple times. This is incredibly useful for understanding an unfolding news story or the evolution of an organization. Unfortunately, over time, some of these original resources can go off-topic and no longer suit the purpose for which the collection was originally created. They can go off-topic due to web site …

Data Transfers After Schrems Ii: The Eu-Us Disagreements Over Data Privacy And National Security, Monika Zalnieriute

Vanderbilt Journal of Transnational Law

In the long-awaited Schrems II decision, the Court of Justice of the European Union (CJEU) took a radical, although not an unexpected, step in invalidating the Privacy Shield Agreement, which facilitated data transfers between the European Union and the United States. Schrems II illuminates long-lasting international disagreements between the EU and the United States over data protection, national security, and the fundamental differences between the public and private approaches to the protection of human rights in the data-driven economy and modern state. This Article approaches the decision via an interdisciplinary lens of international law and international relations and situates it …

Your Body, Your Cells? Direct-To-Consumer Marketing Of Autologous Stem Cell Therapies In The United States, Japan, And Australia, Kathleen C. Laird

Vanderbilt Journal of Transnational Law

Stem cell tourism has relocated; patients in search of stem cell therapies to treat nearly any disease can find clinics selling miracle cures without traveling beyond their national borders. Businesses marketing unproven autologous stem cell therapies are now plentiful in highly regulated, wealthy countries, including the United States, Japan, and Australia. Despite regulatory oversight of stem cell therapies and strong support for scientific innovation in these countries, the internet and social media have facilitated the rapid growth and success of a new industry selling unproven treatments directly to consumers. Clinics selling unproven autologous stem cell therapies have succeeded by developing …

Decitizenizing Asian Pacific American Women, Shoba Sivaprasad Wadhia, Margaret Hu

Faculty Scholarship

The Page Act of 1875 excluded Asian women immigrants from entering the United States, presuming they were prostitutes. This presumption was tragically replicated in the 2021 Atlanta Massacre of six Asian and Asian American women, reinforcing the same harmful prejudices. This Article seeks to illuminate how the Atlanta Massacre is symbolic of larger forms of discrimination, including the harms of decitizenship. These harms include limited access to full citizenship rights due to legal barriers, restricted cultural and political power, and a lack of belonging. The Article concludes that these harms result from the structure of past and present immigration laws …

Streaminghub: Interactive Stream Analysis Workflows, Yasith Jayawardana, Vikas G. Ashok, Sampath Jayarathna

Computer Science Faculty Publications

Reusable data/code and reproducible analyses are foundational to quality research. This aspect, however, is often overlooked when designing interactive stream analysis workflows for time-series data (e.g., eye-tracking data). A mechanism to transmit informative metadata alongside data may allow such workflows to intelligently consume data, propagate metadata to downstream tasks, and thereby auto-generate reusable, reproducible analytic outputs with zero supervision. Moreover, a visual programming interface to design, develop, and execute such workflows may allow rapid prototyping for interdisciplinary research. Capitalizing on these ideas, we propose StreamingHub, a framework to build metadata propagating, interactive stream analysis workflows using visual programming. We conduct …

Closing The Achievement Gap Among Foster Care Children, Ralph Cheriza

Graduate Student Dissertations, Theses, Capstones, and Portfolios

In recent years, the legal landscape has changed to support a framework that guarantees educational stability to foster care students as a subgroup facing myriad adverse developmental outcomes and risk factors that impede academic achievement. In 2013, California has discovered an invisible achievement gap among this distinct subgroup with unrecognized and unmet educational needs. Nationwide, the trend has not been different, prompting a need to get insight into the school setting in Florida to meet the needs of foster care students.

The literature review has suggested that foster care students remain invisible to teachers and have unmet, unstudied, and unrecognizable …

Estimation Of The Capacity Of A Basic Freeway And Weaving Segment Under Traditional, Autonomous, And Connected Autonomous Vehicles, Using Oversaturated Traffic Condition Data, Niloy Saha

Civil and Environmental Engineering

Autonomous vehicles (AVs) and connected autonomous vehicles (CAVs) will be the standard in transportation in the future. The use of such vehicles could minimize traffic oscillation and travel time and boost safety and mobility on freeways. An AV is a self-driving vehicle that can make decisions by itself in any situation. CAVs include all the characteristics of AVs and additional communication with other vehicles or the infrastructure (signal system). The use of AVs and CAVs will substantially increase motorway capacity in upcoming decades. Moreover, vehicle dynamics will change as technology and algorithms become more commonplace. In the short term, capacity …

Bringing Section 8 Home: An Argument For Recognizing A Reasonable Expectation Of Privacy In Metadata Collected From Smart Home Devices, Ana Qarri

Canadian Journal of Law and Technology

Internet of Things devices (also known as smart home devices) are a fast-growing trend in consumer home electronics. The information collected from these devices could prove very useful to law enforcement investigations. These individual pieces of metadata — the collection of which might appear harmless on its face — can be highly revealing when combined with other metadata or information otherwise available to law enforcement. This article builds an argument in favour of recognizing a reasonable expectation of privacy in metadata collected from smart home devices under section 8 of the Canadian Charter of Rights and Freedoms. This article presents …

From Nyan Cat To Nfts: Determining How Canada’S Cultural Property Export And Import Act Applies To Digital Works, Mitchel Fleming

Canadian Journal of Law and Technology

One of Canada’s principal pieces of legislation enacted to protect its cultural patrimony is not well equipped to deal with the rise of digital content creation. Digital works, particularly NFTs, pose a unique challenge to the established regime. This paper seeks to understand how these artistic developments fit within the current legislative framework and whether legislative action is needed to bring these revolutionary mediums within the scope of the Cultural Property Export and Import Act. Ultimately, the author concludes that while digital works may be captured by the Act under specific circumstances, the protectionist policies of the past are …

Contractual Evolution, Matthew Jennejohn, Julian Nyarko, Eric L. Talley

Faculty Scholarship

Conventional wisdom portrays contracts as static distillations of parties’ shared intent at some discrete point in time. In reality, however, contract terms evolve in response to their environments, including new laws, legal interpretations, and economic shocks. While several legal scholars have offered stylized accounts of this evolutionary process, we still lack a coherent, general theory that broadly captures the dynamics of real-world contracting practice. This paper advances such a theory, in which the evolution of contract terms is a byproduct of several key features, including efficiency concerns, information, and sequential learning by attorneys who negotiate several deals over time. Each …

People with IDDs experience an inability to develop necessary employable skills and may be affected by hiring manager perceptions and lack of awareness of available job opportunities. The purpose of this basic qualitative study was to explore hiring managers’ perceptions of hiring individuals with IDDs in competitive integrated employment (CIE) settings in Tennessee. Critical disability theory was used to frame this study. Nine hiring managers in Tennessee who have worked with people with …

Relationship Changes Of African Americans With Nontraditional Spiritual Practices, Della Sanders

Walden Dissertations and Doctoral Studies

Researchers have explored the subject of belongingness for decades. However, there is limited research on how belongingness may change for African Americans who transitioned from traditional Christianity to other spiritual practices. In this study, the relationship changes (in terms of family, friends, significant others, and former church relationships) of African Americans who identify as spiritual but not religious (SBNR) after leaving traditional Christianity were explored. The theoretical framework of the social connectedness theory was used to explore the need for belongingness to avoid social isolation and loneliness within a social network. Six African American Generation Xers, four women and two …
