Exploring The Dynamics Of Romantic Relationships Through The Lens Of Prem Rog, Umang Jain, Dheeraj Sharma, Pranay Goswami, Kuldeep Malik

Journal of Humanistic Mathematics

Romantic relationships are dynamic events that begin, grow, and frequently remain for a long time in a stagnant or fluctuating state until possibly dissipating. Although they are unquestionably the most significant dynamic events in our lives, dynamic systems theory has only recently included them in its formal framework. Without a mathematical model, it would be impossible to analyze and comprehend the dynamics because, in general, love stories are too brief to allow things to stabilize and are affected by the ups and downs of the surrounding community. In this paper, we set up models made up of four ordinary differential …

An Empirical Implementation Of A Two-Standard-Deviation Investment Signaling Framework Across Multiple Asset Classes

Journal of Economics and Finance Education

This paper presents a pedagogically driven application of a quantitative investment signaling model based on two standard deviation bands. Deviations beyond the two standard deviation range are interpreted as potential mean reversion signals, triggering tactical shifts in asset allocation or trading actions. Students construct the models in Excel using live market data, overlaying asset returns against calculated deviation bands to inform decisions. The firsthand approach emphasizes applied learning and critical thinking, with students analyzing model results and presenting empirical findings. Evidence suggests this experiential method significantly enhances student engagement, comprehension, and retention of investment strategy concepts across diverse financial settings

Coase, Thaler, And Behavioral Economics: Methodological Considerations

Journal of Economics and Finance Education

In their experiments to measure the endowment effect in market settings, Kahneman, Knetsch, and Thaler (1990; hereafter KKT) assessed the assumption of zero transaction costs associated with the Coase theorem. Their study recruited a sample of advanced undergraduate economics students who were placed in a market setting using coffee mugs as real-world goods, under conditions in which there were zero transaction costs. Their results suggested that an endowment effect lowered trading volume, which should not have occurred if Coase theorem worked in practice. We reexamine the research design employed by KKT, as well as their study’s statistical analysis and results.

House Of Cards: An Examination Of Missouri’S Inconsistent Tax Assessment Regime And The Questionable Role Of The Court As Arbiter, Isabel Fenoglio

Missouri Law Review

“Taxes are what we pay for civilized society.” No one has offered a simpler rationale for the American tax system than the former Supreme Court Justice Oliver Wendell Holmes, Jr. Despite their inevitability, taxes remain universally dreaded and misunderstood by Americans, but none more so than property taxes. Without property taxes, life as everyday Americans understand it would cease to exist. From streets to schools, from libraries to fire departments, the budgets of indispensable public services, which enable communities to flourish, would collapse.

The main barriers identified were input (logistics, training), process (tracing, education, monitoring), and output …

Microplastics In St. John, United States Virgin Islands Sediments: Methodological Approaches And Variability Of Microplastics Concentrations And Accumulation Rates, Henry B. Arbaugh, Sarah C. Gray, Dimitri Deheyn

Theses

Sediment samples were collected from a near shore and reef site in Coral Bay, St. John, United States Virgin Islands (USVI) from 2007-2016, using tube sediment traps. These samples provide an opportunity to study microplastics (MPs) in an area where no previous MP studies have been performed. Most sedimentary MP studies utilize benthic samples which can only measure MP concentrations (#MP/g or #MP/mL sediment), while sediment traps can provide MP accumulation rates (#MP/cm²/day) as a function of time. However, the methods used for extracting MPs from benthic samples have not been tested using sediment trap samples whose characteristics, …

Electronic Transport In Twisted Bilayer Tungsten Diselenides, Walid Zaher

Theses and Dissertations

This thesis investigates density waves (DWs) in twisted bilayer tungsten diselenide (tWSe₂) using a mean field approximation, with a focus on electron-electron interactions, and the system’s free energy at zero temperature. For the mean field approximation, the study initially employed same-spin nesting vectors, which were found insufficient to induce DWs formation. In contrast, when opposite-spin nesting vectors were used, DWs emerged, indicating that these vectors can support DWs formation. The plots were produced under perfect nesting conditions, where van Hove singularities (VHS) occur. At zero temperature, perfect nesting provides a complete picture of the upper limit of DWs formation, as …

Debiasing Session-Based Recommendation For The Digital Economy: Propensity-Aware Training And Temporal Contrast On Graph Transformers, Junru Si

Double Helix Methodology

Session-based recommender systems (SBRs) are critically impaired by exposure bias in observational training logs, causing models to overfit to logging policies rather than true user preferences. This bias distorts offline evaluation and harms generalization, particularly for long-tail items. To address this, we propose the Propensity- and Temporal-consistency Enhanced Graph Transformer (PTE-GT), a principled framework that enhances a recent interval-aware graph transformer backbone with two synergistic training-time modules. This Graph Neural Network -based architecture is adept at modeling the complex, graph-structured nature of session data, capturing intricate item transitions that sequential models might miss. First, we introduce a propensity-aware (PA) optimization …

Reachability In Interactive Chemical Reaction Networks, Aberto Avila-Jimenez, Bin Fu, Elise Grizzell, Robert Schweller, Tim Wylie

Computer Science Faculty Publications

This paper studies the effects of interactivity on molecular computation, specifically in the Step Chemical Reaction Networks model (Step CRNs), by adding the ability for a user to interact with the system by selecting which species to add at each step, or by having some control over which reactions execute. The two proposed variants are Interactive CRNs and Randomized Interactive CRNs. We show that in Interactive CRNs, even when restricted to void (deletion-only) rules of relatively small size, if a user can decide which species to add at each step based on the configuration, reachability is PSPACE-complete when bounded and …

A Bim-Based Flexible Flow Shop Framework For Scheduling Linear Infrastructure Projects, Mahmoud Mohamed Elbassuony

Theses and Dissertations

Repetitive, multi-stage linear projects, such as pipelines or highways, are primarily impacted by spatial and resource constraints during their execution. Cost overruns, delays, and inefficient resource allocation make construction management for such projects complex. Traditional scheduling techniques, such as Critical Path Method (CPM) and Line of Balance (LOB), are less efficient for scheduling dynamic, complex, and multi-objective projects. There are more advanced scheduling methods that can be applied as a decision-making process to determine the optimal timing of activities and achieve other objectives. One of those techniques is the Flexible Flow Shop model (FFS), which can be effectively applied to …
