Legitimate Interests As A Lawful Ground For The Processing Of Data And Ai Development In The Middle East, Moufid El-Khoury

Sultan Qaboos University Legal Studies Journal

This article addresses the legal basis of legitimate interests for the processing of personal data in the region of the Middle East. Three categories of countries emerge after the survey of selected data protection laws in the region: jurisdictions that explicitly enacted the legitimate interests as a lawful ground for the processing of personal data, those that established a variant of ‘legitimate rights’, and those that omitted the concept of legitimate interests entirely. This article argues that the absence of a lawful ground of processing based on legitimate interests makes the privacy landscape very rigid in some jurisdictions in the …

An Evidence-Based Approach To Fair Use, Clark D. Asay, Cree Jones, Cassidy Mccleary, Stephanie Plamondon

Georgia Law Review

Recent Supreme Court cases have opened the door for market effects to play an even more prominent role in copyright law’s fair use defense to copyright infringement. Historically, however, market effect analysis under fair use’s factor four has either been largely speculative or merely a repackaging of analysis done under the first three factors of the fair use defense. We argue that recent developments in data availability and causal estimation in the social sciences enable litigants and courts in many cases to engage in a more fulsome and credible analysis of market effects in fair use cases. As a proof …

Lawyering In The Wake Of Loper Bright: How Loper Bright Is Shifting Advocates' Argumentation Style, Russell Kiser

Georgia Law Review

The Supreme Court definitively overruled Chevron U.S.A. Inc. v. Natural Resources Defense Council, Inc. in the landmark decision of Loper Bright Enterprises v. Raimondo, marking the most consequential transformation of administrative law in four decades. Prior to Loper Bright, Chevron’s deferential two-step framework provided the standard by which courts interpreted statutes administered by federal agencies. Loper Bright abrogates Chevron’s familiar standard, holding that courts should no longer defer to an agency’s interpretation of its enabling statute whenever the statute is deemed ambiguous. This shift in precedent potentially opens the floodgates for challenges to agency action based …

Pet Shops And Preemption, Genevieve Schaaf

Georgia Law Review

In December 2019, the Georgia Office of the Attorney General released an Opinion stating that the City of Canton Code of Ordinances, Chapter 18, Article XIV restricting the sale of pets by retail pet shops was in direct conflict with the Georgia Animal Protection Act and therefore preempted under the Georgia Constitution’s Uniformity Clause.

This Note seeks reconsideration of the Attorney General’s Opinion and argues that despite the Attorney General’s Opinion, local ordinances restricting the kinds of animals available at pet shops should remain a legally viable way for local governments to reduce the retail sale of cats and dogs.

Monetary Policy Effectiveness Index (Mpei): A Novel Framework For Assessing Central Bank Performance In Developing Economies, Emmanuel Ating Onwioduokit

Bullion

This paper presents the Monetary Policy Effectiveness Index (MPEI), a composite measure designed to evaluate monetary policy in developing economies. Unlike traditional single indicators such as inflation or interest rates, which capture only partial outcomes, the MPEI integrates five key dimensions: price stability, output responsiveness, transmission effectiveness, financial depth and inclusion, and institutional credibility. This multidimensional approach reflects the real policy trade-offs and constraints of developing economies. The index enhances accountability, guides sound policy design, and facilitates meaningful cross-country comparisons and progress monitoring.

The Problem With The Mode Of External Debt Servicing: The Case Of Nigeria, Shehu Tijjani Muhammed

Bullion

This study empirically tested the hypothesis that external debt servicing leads to debt accumulation using Nigeria as case study. The method employed combines logic and debt stock variation analysis. Results indicate that Nigeria has served interest on its external debt only to see its external debt stock increasing confirming the hypothesis. A reform is needed to enable the country retain the domestic income lost to international speculative capital to boost government revenue. A sovereign agency to intermediate between the indebted residents, exporters, and the banking system can be created to solve the problem.

Endogenous Liquidity Shocks And Liquidity Management Dilemma In Nigeria, Temitope J. Laniran, Hamza Abdulaziz, Nuruddeen Usman

Bullion

This paper examines the Central Bank of Nigeria’s (CBN) liquidity management framework over a period marked by aggressive monetary tightening in response to persistent inflationary pressures. The analysis suggested that despite sustained sterilisation efforts through CRR debits and open market operations (OMO), liquidity surpluses persisted, driven largely by autonomous factors such as fiscal injections, maturing OMO bills, and foreign exchange interventions. The resulting structural liquidity surpluses periodically weakened the alignment between short‐term interest rates and the policy corridor, highlighting operational frictions and transmission inefficiencies. The paper opines that heavy reliance on blunt liquidity‐absorbing instruments without addressing the root causes of …

Just like leveling up in a game, dating has transcended the physical world into the realm of multiplayer games where individuals are able to communicate and interact with one another within the virtual third space, the magic circle–the boundary that separates life from play. Within these immersive environments, players create shared experiences that often extend beyond the screen, blurring the line between in-game interactions and real-life emotions. This blurring can lead to emotional spillovers and identity challenges as players navigate the complexities of digital intimacy in world and relationship formation. To define the fluidity of the magic circle, the study …

External Multicenter Validation Of The Esah Score For Predicting Outcomes After Subarachnoid Hemorrhage, Natália Vasconcellos De Oliveira Souza, Rohan Sharma, Otavio Frederico De Toledo, Ingrid Pereira Marques, Salvador F. Gutierrez-Aguirre, Lara-Velazquez Montserrat, Eric Sauvageau, Naval Neeraj, Amin Aghaebrahim, Feres Chaddad Neto, Ricardo A. Hanel, Gisele Sampaio Silva, William David Freeman

Jefferson Hospital Staff Papers and Presentations

Reliable assessment of prognosis after aneurysmal subarachnoid hemorrhage (SAH) is essential to inform clinical decision-making and prevent premature assumptions of poor outcome. The enhanced SAH (eSAH) score combines three routinely available variables-age, Glasgow Coma Scale (GCS), and subarachnoid hemorrhage blood volume (SAHV)-to provide an objective framework for early outcome stratification. SAHV is estimated using the ABC/2-derived ellipsoid method applied across five major cisternal compartments on non-contrast CT. While the eSAH score has shown promise in initial derivation studies, its external performance and calibration have not yet been validated across diverse healthcare settings. We conducted a retrospective cohort study using consecutive …
