Statistical Analysis Of Log Transformation Effectiveness In Air Traffic Movement Forecasting During Covid-19 In South Africa, John Lehlaka Masekoameng

Journal of Aviation Technology and Engineering

This study evaluates the effectiveness of log transformation in enhancing multiple regression models used to forecast air traffic movements (ATMs) in South Africa during the COVID-19 pandemic. Using 60 monthly observations from October 2016 to September 2021, the analysis incorporates variables such as revenue, lockdown levels, COVID-19 metrics, exchange rates, gross domestic product, and population. Two models are compared: one using raw ATMs and another with log-transformed ATMs as the dependent variable.

While the untransformed model shows stronger explanatory power (R² = 0.904, adjusted R² = 0.891) compared to the log-transformed model (R² = 0.772, adjusted R² = 0.741), the …

Monthly and annual CDD calculated with a base temperature of 18°C were obtained from the World Bank Climate Change Knowledge Portal (CCKP) at a spatial resolution of 25 km × 25 km. Percentage changes in CDD were analyzed …

Compassion Or Crisis?: Distinguishing Intent Under § 1324 In Sanctuary And Trafficking Cases, Leah Cussen

University of Chicago Legal Forum

Section 1324 of Title 8 of the U.S. Code prohibits “harboring” undocumented immigrants. But for decades, courts have disagreed over what counts as harboring and what mens rea is required to prove it. These questions have only grown more urgent as immigration has been repeatedly framed as a national crisis. A lack of uniformity in the application of § 1324 has enabled expansive enforcement of the anti-harboring provision, allowing a single statute to target both humanitarian actors providing sanctuary and traffickers exploiting immigrants.

Today, a circuit split reflects two competing approaches. The Third, Fifth, Sixth, and Eighth Circuits use a …

When Disaster Strikes: Assessing The Takings Clause In The Context Of Government-Caused Property Destruction, Abby Berman

University of Chicago Legal Forum

In rare but dire emergencies, the government must destroy the property of innocent homeowners to prevent further harm to a community. Although the law often forgives such destruction to protect the public good, courts have inadequately resolved how to compensate innocent property owners for their losses. This Comment unpacks how doctrine has split among circuit courts regarding whether the Takings Clause requires just compensation for innocent property owners whose property has been destroyed by government action in response to an emergency. As a resolution to this circuit split, this Comment proposes that courts should adopt a multi-factor test, utilizing the …

False Claims, Real Threats: Cybersecurity Noncompliance And The False Claims Act’S Materiality Standard, Charlotte Bairey

University of Chicago Legal Forum

This Comment examines the challenges of applying the False Claims Act’s (FCA) materiality standard to cybersecurity noncompliance by federal contractors. Although the Department of Justice’s Civil Cyber-Fraud Initiative seeks to hold government contractors accountable for misrepresenting their adherence to federal cybersecurity standards, courts have inconsistently applied the “holistic” framework for determining materiality established by the Supreme Court in Universal Health Services v. Escobar. Cybersecurity-related FCA claims face unique obstacles when it comes to showing materiality because noncompliance is widespread, national security interests complicate the government’s payment decisions, and government agencies may continue contracting with noncompliant entities out of necessity. This …

Integrating Human Factors, Technology, And Mental Health: A Mixed-Methods Framework For Aviation Maintenance Safety In The Philippines, Arthur Dela Peña

Journal of Aviation Technology and Engineering

A complex interaction of human factors, mental health, organizational dynamics, and emerging technologies influences aviation maintenance safety in the Philippines. This study aims to develop an integrated framework to address these aspects and reduce maintenance-related errors. Using a mixed-methods approach based on Creswell’s pragmatic paradigm, the research surveyed 200 participants, including aviation maintenance technicians (AMTs), supervisors, and managers, and conducted in-depth interviews and focus groups. Quantitative analysis revealed that fatigue was a significant contributor to maintenance errors, accounting for 45% of recorded incidents and exhibiting a strong correlation with error rates (r = 0.71, p = 0.005).

Based on the thematic analysis conducted, it was identified that evidence-based, scenario-based, and continuous training can be used to reduce runway incursions caused by pilot deviations. The results contribute to …

Realizing The World Health Organization’S Constitutional Mission: Equitably And Everywhere, Sam Halabi, Lawrence Gostin

University of Chicago Legal Forum

COVID-19 revealed deeply embedded inequalities in countries’ capacity to respond to public health disasters. From 2020 to 2024, the content and scope of international health law expanded to address these deep inequities, including a new pandemic agreement and significant changes to the International Health Regulations (IHR). Recent moves by the Trump Administration leveled significant losses on this new global health law infrastructure. At the heart of this infrastructure is the World Health Organization (WHO)—the UN’s specialized agency, which for 77 years has led the world toward realizing the human right to the highest attainable standard of mental and physical health. …

Liability For Disaster Risks, Daniel A. Farber

University of Chicago Legal Forum

A growing body of law addresses liability for harms caused by disasters. The bases for liability are diverse: common law torts, statutes covering specific risks, and takings doctrine. Litigation can involve government or private defendants, while the disaster could be anything from an oil spill to a flood. This Article maps this complex legal terrain and discusses three cross-cutting themes in disaster liability. One theme is the action/inaction distinction, which can create a perverse incentive to postpone or forego mitigation efforts. The second theme involves the interplay between legislatures and courts in designing and implementing liability rules. The final theme …

A Continuum Of Responsibility: An Examination Of The Human Right To A Healthy Environment Of Present And Future Generations, Sarah Dávila A.

University of Chicago Legal Forum

Youth-led advocacy has been at the forefront of the protection of the right to a healthy environment in the face of a triple planetary crisis: loss of biodiversity, environmental degradation, and climate change. Globally, youth have called upon international bodies to provide guidance as to how States and private actors can be held accountable for human right violations. They have demanded that States protect not merely the human rights of present generations, but those of future generations. This Article explores recent developments in international human rights law, including the recent Committee on the Rights of the Child General Comment No. …

The Disaster Management Complex: Law’S Adaptations In Times Of Climate Disaster, Michael Burger, Jeffrey Schlegelmilch, Lucia Bragg

University of Chicago Legal Forum

The Anthropocene is marked by constant climate-related disasters and defined by the urgent need to foster and implement adaptations to future climate impacts that reduce disaster risk. The intensity, frequency, and severity of extreme weather events continue to rise even as nations and corporations alike miss their emissions targets, all promising a hotter, wetter, and more extreme future. A number of federal agencies, including the Federal Emergency Management Agency (FEMA), have, at times, sought to adapt their own famously fragmented responses to these changing circumstances. However, federal disaster response is conducted against a backdrop of authorizing legislation that is designed …

Dual Credit Enrollment And First-Year Undergraduate Experience In Texas: Insights From A Mixed Methods Study, Summer Pannell, Jennifer D. Goddard

School Leadership Review

There has been considerable expansion in the availability of dual credit coursework, however, there is still a lack of understanding regarding how effective these programs are in equipping students for success in post-secondary education (Struhl & Vargas, 2012). This study used a mixed-methods approach to explore the relationships between various components of dual credit programs and the experiences of first-time undergraduate students. The results of a hierarchical multiple regression indicated a statistically significant relationship between the modality of dual credit coursework and students’ first-year undergraduate GPAs but not between the setting of the two factors. Further, the results did not …

Of Blood And The Buddha: A Nichiren Primer On Counseling Clients, John W. Teeter Jr.

Florida Journal of International Law

Should you pray when you bleed? More specifically, should a Buddhist woman refrain from chanting and reciting from the Lotus Sutra during her menstrual cycle? This was the query fielded by the fiery prophet Nichiren in 1264 in Kamakura, Japan. Nichiren's response, however, is far more than a doctrinal resolution of an esoteric theological uncertainty. To the contrary, Nichiren's advice is a model of analysis, common sense, and compassion that today's attorneys would be wise to emulate. As set forth below, Nichiren's cautious, sensitive, and pragmatic approach provides an enlightened template on how we can best counsel our clients in …

The Consequences Of Attempted Human Perfection: Genetic Enhancement And Why It Is Immoral, Kiran S. Sajnani

Mako: NSU Undergraduate Student Journal

In the field of biomedical ethics, genetic enhancement—the alteration of human DNA to increase characteristics beyond normal function—is a highly contested topic. Genetic enhancement presents serious ethical issues, especially when gene therapy seeks to treat or prevent disease. This paper makes the consequentialist case that genetic enhancement, whether somatic or germline, is intrinsically unethical because of its ethical, societal, and systemic ramifications. The autonomy of future persons is violated by germline enhancement, which also runs the risk of deepening socioeconomic gaps and escalating intergenerational inequity. Even though it only affects the individual, somatic augmentation undermines human diversity and agency by …

The Educational Leadership Trajectories Of Black Gay Males: A Narrative Inquiry, Abidemi Omowale Kayode

Student Theses and Dissertations

This qualitative study examines the educational leadership trajectories of Black gay men (BGM) working in K-12 public schools. These BGM navigate identity-centered marginalization from school systems. Their leadership development is shaped by structural barriers, exclusive frameworks, and cultural expectations whether visible or invisible. This study addresses the scant literature in educational leadership around intersecting racial and sexual identities, and how this omission contributes to exclusionary and discriminatory trauma for BGM. These inequities are supported by heteronormative adult cultures, interpersonal dynamics, and policy. The consequences of these inequities are both political and professional as well as psychologically harmful and deeply personal. …
