The Impact Of Inattentive Respondents And The Efficacy Of Quality Control Checks In Online Surveys, Tammy Mccullough, Sam Fullerton

Global Advances in Business Communication

An online survey provided insight regarding problems associated with inattentive respondents when collecting primary data using an Internet interface. Rather than open-access, respondents were part of a commercially maintained consumer panel. Inattentive respondents were identified using three quality control checks: an instructional manipulation, a common knowledge question, and a time check. Of the 1,452 respondents who completed the 83-question survey, 511 respondents (35.19%) failed at least one quality control check; 59 (4.06%) failed all three. Deviations between inattentive and attentive respondents were identified. For the instructional manipulation and the common knowledge checks, the impact of the inattentive respondents depended upon …

Kinetic Analysis Of 2-Methylpentan-2-Ol*, Nicole Seheult

Campus Research Month

This experiment investigated the kinetics of 2-methylpentan-2-ol using UV-visible spectroscopy under strongly acidic conditions (96% sulfuric acid). The dehydration of the tert-amyl alcohol produced a carbocation intermediate whose absorbance at 300 nm was evaluated at various temperatures. An Arrhenius plot of ln(k) versus 1/T produced a linear relationship with a calculated activation energy of 90.0 kJ/mol. This value is consistent with literature expectations for tertiary carbocation formation and supports the acid-catalyzed dehydration mechanism predicted for this molecule.

We improved the UI and UX using Nielsen's usability heuristics, reduced navigation complexity, and redesigned the emergency workflow for deliberate, fast interaction.

Redesigning A Fitness App Interface For Physiological Constrained Users*, Joseph E. Manzanillo

Campus Research Month

As fitness tracking converges with medical monitoring, inclusive design becomes a matter of health equity. This research utilizes a Polar Beat redesign to address exclusionary "sporty" aesthetics that can exclude 300 million colorblind users. Based in Human-Computer Interaction (HCI), the study implements WCAG AA standards and color-blind-verified filters to mitigate data loss during Situational Induced Impairment (SIID), when high-intensity exercise compromises cognitive and visual processing. By optimizing user journeys for Paralympic and geriatric archetypes, this work demonstrates that accessibility is the essential bridge transitioning mobile fitness apps into viable, inclusive instruments for clinical medical use.

Indexed Concatenation (I-Cat): A Method For Representing And Operating On Repeating Numbers*, Abigail Touma, Isaac Wolford

Campus Research Month

Our research presents Indexed Concatenation (I-Cat) notation as a structured way to represent numbers with repeating patterns, including both decimals and whole numbers. Instead of treating expressions like 0.333... or 735735735 as unstructured expansions, they are rewritten as compact repeating objects called I-Cats. The presentation demonstrates how arithmetic operations, including addition and multiplication, can be performed using hypothesized rules such as the "U = M/C" method, unpacking, and carry propagation. Examples progress from simple conversions and multiplication by integers to the multiplication of two I-Cats. A live visual demonstration will show how standard numerics transform into I-Cat form and how …

Which Is The Most Effective Study Break: Movement, Media, Or Rest?*, Emily R. Grant, Kalla Carballo, Aislin Robinson

Campus Research Month

College students frequently incorporate breaks of various types into their study sessions; however, limited research has examined how different types of breaks affect memory retention. The proposed study will examine how exercising, spending time on social media, or participating in quiet rest affect delayed recall among undergraduate college students. The study predicts that students who participate in an exercise break will show improved memory retention, while students who are exposed to social media will experience reduced memory retention. The study also hypothesizes that students who are assigned to the quiet rest condition will demonstrate no significant change in retention. Undergraduate …

A Strategic Roadmap For Assessing And Educating On Personal Cybersecurity Practices In Universities*, Ryan Lopez, Ysani Peña

Towards Physics-Informed Neural Networks For Simulating Multiphase Geothermal Convection​*, Daniel C. Patton, Andrew Harrison Eno

Campus Research Month

Water and steam flow through porous rock, transferring heat via conduction and buoyancy-driven convection caused by density differences. Traditional numerical methods (finite-volume/finite-element) model this well but can become memory-intensive and unstable for long, high-detail simulations. This work demonstrates a Physics-Informed Neural Network (PINN) using a finite-difference approach within the NVIDIA PhysicsNeMo framework to simulate magma chambers in 2D. Tested on the Rio Pisco pluton in Peru, results are compared with the USGS HYDROTHERM model. PINNs learn from physical laws, offering accurate, flexible solutions with less data and development effort.

Revisiting Quantum Foundations: Deriving The Klein-Gordon-Fock Equation Without Axiomatic Postulates*, Joshua Lohr, Vola Andrianarijaona, Anton A. Lipovka

Campus Research Month

This paper presents a derivation of the Klein-Gordon-Fock equation from first principles. The proposed method eliminates the need to axiomatically postulate wave functions or equation coefficients. Instead, the derivation is performed on an adiabatically variable manifold, locally described by the Friedman-Robertson-Walker metric, incorporating complete electrodynamics. In this framework, the transverse electromagnetic field quantizes due to adiabatic changes in the metric tensor, with Planck's constant serving as its adiabatic invariant. Consequently, wave functions naturally emerge as eigenfunctions of a Sturm-Liouville problem used to expand the electromagnetic field.

Towards Smaller Artificial Neural Network Using Mean Compression*, Michael D. Burks, Matthew K. Chuhng

Campus Research Month

Artificial Neural Networks (ANNs) require substantial memory and computational resources, limiting their deployment on resource-constrained devices. Our contribution is a compression method using Mean Compression (MC) to reduce ANN size while preserving functionality and accuracy. MC consolidates connections with similar edge weights into meta-nodes with averaged values. Unlike traditional pruning that only removes connections among neurons, MC restructures networks by recomputing weights and creating meta-nodes. Additionally, unlike fixed pruning thresholds, MC uses flexible weight range patterns. Applied to multilayer perceptron (MLP), ANNs are made more accessible for deployment on constrained devices as proven in several experiments. Specifically, across five classification …
