Ai And The Legal Puzzle: Filling Gaps, But Missing Pieces, Joseph Anderson

Mercer Law Review

One of the foremost concerns arising from artificial intelligence’s penetration into the legal realm revolves around accountability and transparency. Traditional legal processes entail a human-driven decision-making paradigm, with judges, lawyers, and legal professionals accountable for their judgments and actions. However, as artificial intelligence systems grow more complex, they often operate as ‘black boxes,’ making it challenging to decipher the rationale behind their decisions. This opacity raises questions about how to attribute legal liability when AI-powered systems make errors or biased judgments. Striking a balance between the efficiency of artificial intelligence and the transparency required in legal proceedings is a pressing …

What About Us? How Law Schools Can Help Historically Underrepresented Law Students Develop Their Professional Identities, David A. Grenardo

Mercer Law Review

Talking about race, gender, and sexual orientation can be painful, messy, and difficult. This country’s history of discrimination and violence against historically underrepresented, marginalized, excluded individuals—racial and ethnic minorities, women, LGBTQIA+, those living with disabilities, the socioeconomically disadvantaged/lower class—makes these topics fraught with controversy and risk. We can easily offend someone accidentally when we try to address these topics even with the best of intentions. For example, some people may get nervous trying to figure out whether to use the words African-American, Black, BIPOC, person of color, or all of the above when discussing these topics and referring to someone …

Just Me, Myself, And I: Georgia Trial Courts May Consider Pro Se Motions Filed By Represented Criminal Defendants, Mckayla A. Doss

Mercer Law Review

For decades, Georgia’s trial courts have applied the absolute rule that pro se motions filed by represented (or presumably represented) criminal defendants were a legal nullity. In essence, hybrid representation was not permitted—legal representation precluded criminal defendants from acting as “co-counsel” or filing their own pro se motions.The application of this absolute rule substantially affected the time-sensitive period that follows a criminal conviction, as defendants in Georgia have a limited period of time to file a notice of appeal or a motion for new trial before the window of direct appeal closes. Failure to file these motions results in the …

A (Not-So) “Minor” Application Of The “Spousal Standing” Exception To Georgia’S Wrongful Death Act, Kelly N. Lafleur

Mercer Law Review

The death of a loved one is a tragedy, especially when allegations of wrongdoing exist surrounding the death, and the decision to bring a lawsuit is a deeply personal matter. But who bears the burden of making that decision—the deceased’s spouse, their child, or another loved one? The answer may depend on the court’s application of equitable principles to preserve the claim.

Georgia’s Wrongful Death Act grants a decedent’s surviving spouse the right to pursue a wrongful death claim. In the event there is no surviving spouse, that right is granted to the decedent’s “child or children, either minor or …

3d Bioprinting The Tumor Microenvironment For Immunotherapy Development, Molly Leyda, Tykeem Manor, John Szarejko, Douglas Myers, John M. Perry

Posters

The tumor microenvironment (TME) is a complex system that plays a crucial role in tumor progression, immune evasion, and therapy resistance. The TME is composed of various cell types, including tumor cells, stromal cells, and immune cells such as macrophages. Macrophages are versatile myeloid cells which can exhibit both pro-tumoral and anti-tumoral functions, depending on their phenotype and the TME context. M1 macrophages have demonstrated promising pro-inflammatory and anti-tumor effects, while tumor associated M2 macrophages (TAMs) play an anti-inflammatory role and promote tumor immune escape. Understanding the complex interactions between TAMs and the TME is, therefore, essential for developing effective …

How Traditional Legal Rhetoric's Myth Of Neutrality Sustains Capitalism, Elizabeth E. Berenguer

Denver Law Review

Through the lens of critical and comparative rhetoric, this Article examines how traditional legal rhetoric—the dominant analytical framework employed in the United States legal system—sustains capitalism and preserves inequities, such as financial precarity. This Article identifies the features that traditional legal rhetoric shares with the free capitalist market and then uses those features as an analytical framework to examine two cases that align with the theme of this Symposium on financial precarity and late capitalism: Bank of America v. Caulkett and Citizens United v. FEC. Comparing these two cases, the Court uses the same analytical tools of traditional legal rhetoric, …

The Social Cost Of Unpaid Student Loans, Brooke E. Gotberg, Evan Miller

Denver Law Review

Federal student loans represent a multibillion-dollar investment by American taxpayers. Although most student loans are repaid on time, a significant minority of borrowers struggle to repay their debts. This is particularly true when the education obtained using the loans does not translate into higher earning potential for the borrower. Policymakers have periodically focused attention on easing the burden of student debt. The sympathetic plight of many borrowers makes it easy to consider only their best interests. However, on the opposite side of every debtor is a creditor; in this case, it is the federal government as a representative of taxpayers. …

A User-Centric Continuous Authentication Modality Evaluation And Selection Scheme, Bharath R. Senthilkumar

Master's Theses

One of one-time authentication’s most prominent vulnerabilities is the possibility of lunchtime attacks. In such scenarios, an adversary could exploit an unattended device with an active session and no measures are taken to prevent them from committing malicious acts. To address this issue, continuous authentication is utilized by continuously verifying whether an individual is a device’s rightful owner through various modalities, with data sourced from sensors. In the current body of research within this rising domain, various single-modal and multi-modal continuous authentication systems exist, that focus on employing unique combinations of modalities and improving existing supervised learning models used to …

Causal Inference Using Bayesian Network For Search And Rescue, Amanda Belden

Master's Theses

People who are considered missing have much higher probabilities of being found dead compared to those who are not considered missing in terms of Search and Rescue (SAR) missions. Dementia patients are incredibly likely to be declared missing, and in fact after removing those with dementia the probability of the mission being regarded as missing person case is only about 10%. Additionally, those who go missing are much more likely to be on private land than on protected areas such as forests and parks. These and similar associations can be represented and investigated using a Bayesian network that has been …
