The Effectiveness Of Casual Group Learning In Introductory Finance Tutorials

Journal of Economics and Finance Education

Many universities require introductory financial management for undergraduate business majors. This study measures whether classroom study groups have a more positive effect on student perceptions and performance than traditional teacher driven classes. As an alternative to traditional tutorial teaching, Classroom Study Groups is an application of casual group learning and is consistent with Constructivist learning theories. The study reports significant differences between the two approaches, with student engagement and satisfaction reported at higher levels amongst those students involved in the traditional, teacher-led approach, and no significant difference between the two in regard to student performance. Interesting relationships are found between …

Is There A Link Between Performance In International Economics Courses And Academic Success?

Journal of Economics and Finance Education

This paper uses a sample of 6,470 students and Maximum Likelihood Estimation to determine the relationship between grades received in international economics courses and academic success of business majors. The results indicate that the grades earned in international economics courses as well as the number of international economics courses are significant and positive determinants of students’ final GPA.

A Brief Introduction To Marginal Analysis For The Micro-Economics Principles Course

Journal of Economics and Finance Education

This brief note provides a simple, yet powerful example of how the marginal cost/marginal benefit principle can be used in everyday life. Using the decision of the optimal choice of speed on the highway, this note was developed for use as one of the first readings in an introductory microeconomics course. It is clear in this demonstration that marginal cost is increasing, while marginal benefit is decreasing, and how the intersection of these two curves shows the optimal choice. In addition, shifts in the curves can easily be demonstrated as an introduction to supply and demand.

Sglt2 Inhibitors In Diabetes Management: Mechanisms, Clinical Benefits, And Expanding Therapeutic Frontiers, Naiyer Shahzad, Nahla Ayoub

Saudi Toxicology Journal

The kidneys play a vital role in renal glucose reabsorption, with the sodium-glucose cotransporter-2 (SGLT2) in the proximal renal tubules performing a crucial function in reabsorbing glucose into the bloodstream. SGLT2-selective inhibitors are a new class of oral antidiabetic drugs that enhance glycemic control in diabetic patients by blocking glucose reabsorption. These drugs are primarily developed to treat type 2 diabetes mellitus (T2DM). This review summarizes the latest preclinical and clinical trials on SGLT2 inhibitors. These new oral antidiabetic agents effectively and selectively block SGLT2, leading to a reduction in blood glucose levels and HbA1c in both diabetic animal models …

What Matters To Residential Long-Term Care Residents: Contextualizing Perceptions Of Person-Centered Care, Luis J. Cordero, Sarah Dys, Diana White

Institute on Aging Publications

This study combines the CRITIC and DEMATEL methods and introduces a new hybrid scenario analysis approach that identifies cross-scenario strategies. We use Taiwan's wind energy industry as a case study to validate the process. Although scenario analysis has been applied across various fields and organization types—including strategic planning, education, training, and recent environmental issues—scholars have highlighted problems such as the subjectivity of qualitative analysis and the lack of quantitative evidence. To address this, this study integrates scenario analysis with quantitative multi-criteria decision analysis to support decision makers in conducting scenario evaluations. We achieve this by applying a multi-criteria approach to …

Developing A Novel Typology Of Unprofessional Behaviours Between Healthcare Staff: A Best Fit Framework Synthesis, Justin Aunger, Ruth Abrams, Russell Mannion, Aled Jones, Judy M. Wright, Johanna I. Westbrook, Mark Pearson, Jill Maben

School of Nursing and Midwifery

Background: Unprofessional behaviours such as bullying, harassment, and microaggressions negatively affect patient safety and staff psychological wellbeing in healthcare systems globally. These behaviours do so by: (i) inhibiting health care professionals’ abilities to speak up to raise safety concerns; (ii) impairing team communication and individuals’ concentration; and (iii) promoting tolerance of bad practice. Unfortunately, there is little consensus in practice or academia about how these behaviours are defined. This can lead to an underestimation of the prevalence of these behaviours, inhibition of speaking up by victims and bystanders, and reduced accountability by those who enact these behaviours. We aimed to …

From Kickbacks To False Claims: The Causation Consequences Of The 2010 Anti-Kickback Statute Amendment, Daniella Stoltz

University of Chicago Legal Forum

The 2010 amendment to the Anti-Kickback Statute (AKS) sought to strengthen federal healthcare fraud enforcement by clarifying that Medicare and Medicaid claims submitted to the government “resulting from” AKS violations constitute false claims under the False Claims Act (FCA). However, two words, “resulting from,” have created a deep circuit split over the requisite causation standard. The First, Sixth, and Eighth Circuits require but-for causation, demanding proof that false claims would not have been submitted but-for the illegal kickback. The Third Circuit adopted a looser standard, requiring only some evidence of the illegal kickback and the submitted claim. Rather than focus …

When The Rules Burn: A New Approach To Governmental Discretion In Firefighting Operations, Nathan Li

University of Chicago Legal Forum

The Federal Tort Claims Act (FTCA) broadly waives the federal government’s sovereign immunity, but the discretionary function exception (DFE) preserves immunity for acts grounded in judgment or choice. A doctrinal tension arises from the Supreme Court’s instruction in Berkovitz v. United States that the DFE does not apply when a directive “specifically prescribes a course of action.” In high stakes contexts such as wildfire suppression, government actors sometimes deviate from such mandatory directives to make split-second, policy-driven decisions. Yet, in most cases, courts still treat these violations as discretionary acts protected by the DFE, often without explaining how this outcome …

Reckoning With Retaliation: Objective Reasonableness In Sox Whistleblower Cases, Jacob S. Levin

University of Chicago Legal Forum

Congress passed the Sarbanes-Oxley Act of 2002 to prevent systemic fraud. To this end, Congress included unparalleled anti-retaliation protections for whistleblowers in 28 U.S.C. § 1514A, aimed expressly at ending the “corporate code of silence” which enabled large-scale fraud to go undetected.

To fall within the scope of SOX’s anti-retaliation provisions, a whistleblower must demonstrate he had an “objectively reasonable belief” that his employer’s conduct violated the laws or regulations enumerated in § 1514A. However, the Act does not define what a whistleblower must show to establish an “objectively reasonable belief” that their employer engaged in fraudulent conduct. Over time, …

Beyond Elrod: Extending The Presumption Of Irreparable Harm To The Second Amendment, Roland Kim

University of Chicago Legal Forum

In response to gun violence, many states have attempted to implement gun control laws. Some of these gun control laws have been challenged under the Second Amendment, with parties seeking preliminary injunctions to halt these laws’ enforcement until a final judicial decision has been reached.

In legal disputes over whether to grant a preliminary injunction over various gun control laws, circuits are split as to whether an alleged violation of the Second Amendment is presumptively irreparable, i.e., unable to be adequately remedied after a final judgment. In the First Amendment context, the Supreme Court established in Elrod v. Burns that …

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 …

Vapes In Violation: The Case For An Fdca-Based Negligence Per Se Claim Against E-Cigarette Manufacturers, Grace Hering

University of Chicago Legal Forum

The unexpected and dramatic rise in youth e-cigarette consumption in the past decade has left both private and public actors racing to catch up to a quickly evolving and potentially disastrous market. As litigation against e-cigarette manufacturers continues to develop, it is increasingly evident that one of the biggest obstacles to bringing private claims will be avoiding preemption under the Federal Food, Drug, and Cosmetic Act (FDCA).

This Comment argues that one untested yet promising pathway for injured plaintiffs to avoid preemption is to bring FDCA-based negligence per se claims. By examining precedent involving other FDCA provisions, this Comment assesses …

Curfew And Its Constitutional Limits: Analyzing The Judicial Standard Of Review For Curfews In Times Of Emergency, Alec Greven

University of Chicago Legal Forum

Curfews imposed against an entire civilian population are extremely rare. Despite this, the amount of curfews has recently skyrocketed in the United States as government officials use this sweeping power to respond to emergencies. This Comment evaluates the constitutional rights implicated by general curfew orders, namely the right to travel and the right to speak in public forums. Then, this Comment surveys the current circuit split. Lower courts significantly diverge in their standard of review of curfew orders and apply three very different forms of review: deference, intermediate scrutiny, and strict scrutiny. This Comment argues that courts should subject general …

Climate Change Impact On Cooling Energy Demand Of Major Airports In Nigeria, Abdullah C. Salihu, Yahaya Z. Ibrahim, Rukayyat Abdulkarim, Emmanuel I. Aruya

Journal of Aviation Technology and Engineering

Rising global temperatures due to climate change are intensifying the cooling energy demands of critical infrastructure, including airports. This study assesses the impact of climate change on the cooling energy needs of five major international airports in Nigeria (Abuja, Enugu, Kano, Lagos, and Port Harcourt) using cooling degree days (CDDs) derived from the Coupled Model Intercomparison Project (CMIP6) multi-model ensemble climate projections. 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.

Advanced Qualification Program Assessments In Aviation Higher Education: A Theoretical Framework, Jorge L. D. Albelo Ph.D., Victor M. Fraticelli Rivera Ph.D.

Journal of Aviation Technology and Engineering

This study investigates the integration of an Advanced Qualification Program (AQP)-centered approach into aviation higher education, aiming to refine assessment methods and enhance the educational experience of future aviation professionals. Guided by research questions exploring the strengths, limitations, key characteristics, and potential improvements of AQP-centered assessments, the study reveals a strong consensus among students and faculty. The AQP model, traditionally an alternative to conventional pilot training under 14 CFR Parts 121 and 135, offers a structured, industry-relevant framework emphasizing clear evaluation processes, multilevel knowledge and skill assessments, and high academic performance. Findings indicate that effective AQP assessments balance theoretical knowledge, …

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 …

Killer Heat: The Disaster Fema Refuses To Own, Robert R.M. Verchick

University of Chicago Legal Forum

Extreme heat, also known as a “heatwave,” is by far the leading weather-related cause of death in the United States.1 In 2023, extreme heat took 2,300 lives—more than all the deaths attributed to hurricanes, earthquakes, tornadoes, droughts, wildfires, winter storms, and floods combined. Harms from extreme heat, which are especially severe in disadvantaged communities, will only increase as the climate continues to break down. Despite these facts, in more than 70 years of comprehensive disaster response, no president has ever declared a “major disaster” based on extreme heat, nor has the Federal Emergency Management Agency (FEMA) ever recommended he do …

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). Incorporating human factors …

Majority Rule And Bankruptcy Resolution Of Mass-Harm Events, Sarah Paterson, Adrian Walters

University of Chicago Legal Forum

Mass-harm events invariably precipitate mass tort liabilities. Since the enactment of the Bankruptcy Code in 1978, firms have resorted to Chapter 11 to address mass tort claims in cases involving asbestos-related disease, defective products, the opioid crisis, and historic sexual abuse. Of late, the use of bankruptcy to resolve mass tort claims has been the subject of sustained criticism from inside and outside bankruptcy law’s professional and academic communities. Much of this has been provoked by the Purdue Pharma filing and the bankruptcy court’s approval of a plan of reorganization that created a liability shield for the Sackler family in …

Vaccines For Pandemics: Lessons From Covid-19 For H5n1 And Beyond, Alison Mccarthy, Michael S. Sinha

University of Chicago Legal Forum

The COVID-19 pandemic brought unprecedented challenges to vaccine development and distribution. Never before has a vaccine been developed so quickly and distributed so rapidly. But compared to past pandemics and public health crises—like polio or even the more recent H1N1 pandemic—the United States government’s COVID-19 vaccine strategy depended greatly on the private sector.

COVID-19 vaccines were credited with saving millions of lives worldwide, but private companies reaped these rewards, retained their patent rights, and profited from the vast and pressing need for their vaccines. Now, five years later, not every company views its vaccine work as a success. Financial hits …

Emergencies, Alien And Domestic, Samuel Issacharoff

University of Chicago Legal Forum

Democracies survive some emergencies, even emerging stronger after some crises despite temporary suspensions of liberty. Democracies die when faced with other emergencies. This Article explores why. It addresses the claimed need to limit rights of electoral participation in response to the rise of antidemocratic forces through the lens of militant democracy in Europe and the Insurrection Clause of Section Three of the Fourteenth Amendment in the United States. When examined through the context of claimed exigency, the ability of democracies to survive or even thrive after emergencies turns heavily on whether the source of the perceived threat is foreign or …

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. …
