A Probabilistic Model For Measuring Stock Returns And The Returns From Playing Lottery Tickets: The Basis Of An Instructional Activity

Journal of Economics and Finance Education

Many individuals indicate that playing the lottery is a legitimate way to generate wealth, including retirement savings. We offer a methodology designed to create interactive learning activities comparing the results of playing the lottery versus investing in stocks to create wealth. To emphasize the stochastic nature of investment and lottery returns, we employ a Monte Carlo simulation that draws from probability distributions created from lottery payoffs and historical stock returns. The model results demonstrate, visually and numerically that stock investments generally outperform the lottery in generating wealth.

From Operations To Outcomes: The Role Of Industry 4.0 In Customer Management And Financial Performance, Hong Long Chen

Management Dynamics

Despite extensive research on Industry 4.0 (I4.0) technologies, relatively little attention has been given to their impact on financial performance at the firm level. This study proposes a model to investigate the links between I4.0 implementation level (I4.0IL), supply chain management performance (SCMP), customer management performance (CMP), and company financial outcomes using bootstrap-based structural equation modeling (SEM) with data from 91 companies across various sectors. The results of the bootstrap-based SEM with 1,000 resamples show that SCMP significantly influences both CMP and company financial performance, and CMP also significantly impacts financial performance. While I4.0IL does not significantly amplify the effects …

Fuzzy Pi Controller For Frequency Control Of A Diesel-Pv-Battery-Based Islanded Ac Microgrid, M. S. Elborlsy, Ramadan M. Mostafa, Hossam E. Keshta, Mohamed A. Ghalib

Mansoura Engineering Journal

Effective management of modern electrical grids requires intelligent and adaptable control mechanisms to effectively balance power supply and demand, particularly in times of significant disturbances. Microgrids predominantly harness renewable energy sources (RES), which are inherently variable, for electricity generation. However, due to these fluctuations, conventional control systems often struggle to optimize performance under diverse operational conditions. This study addresses the need for improved frequency regulation in isolated AC microgrids (MGs) by proposing a fuzzy PI (FPI) controller capable of dynamically adjusting control strategies to accommodate disturbances such as three-phase faults, sudden changes in load, and variations in solar irradiance. A …

A Transferable Force Field For Simulating Adsorption In Metal–Organic Frameworks With Open Metal Sites Based On The 12–6–4 Lennard-Jones Potential, Meng Du, Alan Rodriguez, Matthew Z. Lin, Haoyuan Chen

Physics & Astronomy Faculty Publications

Metal–organic frameworks (MOFs) that contain coordinatively unsaturated open metal sites (OMSs) provide strong host–guest interactions, making them promising sorbents for low-concentration gas adsorption applications such as direct air capture and atmospheric water harvesting. However, accurately modeling host–guest interactions involving OMSs remains challenging for classical force fields (FFs) based on the 12–6 Lennard–Jones (LJ) potential, as the polarization effect of the guest molecule induced by the positively charged OMS is not considered. Here, we introduce an FF based on the 12–6–4 LJ potential, which incorporates charge–induced dipole interactions and is parametrized against a diverse set of host–guest potential energy surfaces (PESs) …

The Role Of Side-Chain Length And Counterion Mediation On Dimerization Of Rigid Sphere-Rod Amphiphiles: A Molecular Dynamics Investigation, Mesfin Tsige, Tianbo Liu, Javad Tamnanloo, Abdol Hadi Mokarizadeh

University Research

Rigid sphere-rod amphiphiles (RSRAs) comprising a Keggin polyoxometalate (POM) headgroup and an oligofluorene rod with different side chain lengths (C2, C6, C10, C16, are the number of carbon atoms per side chain) were probed by all-atom molecular dynamics in THF/water mixtures (15 and 33 vol % THF) with tetrabutylammonium (TBA+) counterions to elucidate the molecular origins of dimerization. Despite strong Keggin-Keggin electrostatic repulsion, stable dimers form through a synergy of (i) hydrophobic rod/side-chain interaction that strengthens with side-chain length and (ii) counterion-mediated attraction by TBA+, which localizes near the Keggins to screen electrostatic repulsion. Packing evolves from near-parallel rods for …

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 …

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 …

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.

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 …

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 …

Exploring The Reduction Of Runway Incursions Through Training, Vasilios (Billy) Constaintine Metallinos

Runway incursions are prevalent aviation safety issues that result in adverse outcomes. The focus of this qualitative case study was exploring the reduction of runway incursions through training for pilots. Applying social cognitive theory (SCT) provided this study with a theoretical underpinning. Conducting interviews and a focus group with 17 participants allowed for the collection of enough data and resulted in identifying the importance of training in preventing runway incursions. 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 …

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 …

Math Skills And Everyday Problem Solving

Journal of Economics and Finance Education

Given the importance of mathematics to economic education, we administer a test of basic math skills to 696 students enrolled in various college economics courses in order to understand the factors influencing a student’s ability to apply basic math skills in practical settings. Students with strong elementary math skills perform significantly better in applied contexts and we find that taking more math classes in college improves a student’s ability to apply mathematics substantially. Interestingly, our results suggest that students with greater personal financial responsibility in funding their education do significantly better in understanding and applying basic math skills.
