Light And Dark Mode: A Comparison Between Android And Ios App Ui Modes And Interviews With App Designers And Developers, Sarah Andrew, Chelsea Bishop, Garreth W. Tigwell

Articles

Mobile app light and dark modes offer improved usability within different contexts (e.g., dark mode for easier night reading). Yet, little research has investigated the prevalence of light and dark modes across platforms, the intricacies of UI color changes, and challenges in the design and development process. Our investigation focused on comparing light and dark mode designs. We carried out a manual inspection of 120 popular Android and iOS apps to find that only 55\% (Android) and 48\% (iOS) of the apps included any modes. We also found significant variability in how many UI elements changed between modes. We interviewed …

Writing With Ai: University Students’ Use Of Chatgpt, Nikola Crcek, Jakob Patekar

Articles

Background: ChatGPT, a chatbot based on a large language model, captured global attention toward the end of 2022. With its potential to generate comprehensive texts of a variety of genres based on a string of straightforward prompts, it was soon perceived as a threat by many in various fields, including – and in particular – education. Schools across the world began banning its use as instructors started to receive suspiciously well-written essays and assignments from their students.

Aim: This study aimed to investigate the prevalence of use of ChatGPT among university students for written assignments, explore the ways students utilize …

Up To Code: Lessons Learned In Evaluating And Improving Legacy Irs, Frances Chang Andreu

Articles

Not all repositories are created under ideal circumstances, and inheriting an institutional repository can present challenges distinct from building one from scratch. Changes in institutional vision, policies, and priorities can lead to inconsistent content and limited metadata. Lack of documentation and loss of institutional memory can result in uncertainty about previous decisions. This case study examines the process of auditing a legacy institutional repository in order to ensure the content best reflects the institution’s current goals and policies.

A Primer On The Legendre Transformation, Steven J. Kilner, David L. Farnsworth

Articles

Guidance is offered for understanding and using the Legendre transformation and its associated duality among functions and curves. The genesis of this paper was encounters with colleagues and students asking about the transformation. A main feature is simplicity of exposition, while keeping in mind the purpose or application for using the transformation.

Probability Distributions Arising In Connection With The Inspection Paradox For Bernoulli Trials., James E. Marengo, Anne Marino Himes, W. Cade Reinberger, David L. Farnsworth

Articles

In renewal theory, the Inspection Paradox refers to the fact that an interarrival period in a renewal process which contains a fixed inspection time tends to be longer than one for the corresponding uninspected process. We focus on the paradox for Bernoulli trials. Probability distributions and moments for the lengths of the interarrival periods are derived for the inspected process, and we compare them to those for the uninspected case.

The State Of Accessibility In Blackboard: Survey And User Reviews Case Study, Mohamed Wiem Mkaouer, Wajdi Aljedaani, Stephanie Ludi, Mohammed Alkahtani, Marcelo M. Eler, Marouane Kessentini, Ali Ouni

Articles

Context: Nowadays, mobile applications (or apps) have become vital in our daily life, particularly within education. Many institutions increasingly rely on mobile apps to provide access to all their students. However, many education mobile apps remain inaccessible to users with disabilities who need to utilize accessibility features like talkback or screen reader features. Accessibility features have to be considered in mobile apps to foster equity and inclusion in the educational environment allowing to use of such apps without limitations. Gaps in the accessibility to educational systems persist.

Objective: In this paper, we focus on the accessibility of the Blackboard mobile …

Enhanced Internal Coating Structure And Light Reflectance Of Coated Papers: A Sludge Valorization Process, Bilge N. Altay, Anamika Huq, Burak Aksoy, Richard Hailstone, Muslum Demir, Cem Aydemir, Arif Karademir, Scott Williams

Articles

Paper mill sludge (PMS) is a high-volume waste of the pulppapermaking industry, containing cellulose fibers. This paper introduces cellulose nanofibers extracted from PMS (CNFsPMS) and their application in paper coatings using a wire-wound coating method to enhance internal and optical properties of paper. Three factors were investigated: (i) CNFsPMS amount, (ii) number of layers, and (iii) surface treatment via a 4 × 2 × 2 factorial design. The experimental responses were tracked by fundamentally important internal properties including porosity, air permeability, thickness, roughness, and optical properties of brightness, gloss, and CIE L*a*b* color coordination. The results showed that CNFPMS enhances …

Probability Distributions Arising In Connection With The Inspection Paradox For The Poisson Process, James E. Marengo, Anne Marino Himes, David L. Farnsworth, W. Cade Reinberger

Articles

The Inspection Paradox refers to the fact that in a Renewal Process, the length of the interarrival period which contains a fixed time is stochastically larger than the length of a typical interarrival period. To provide a more complete understanding of this phenomenon, conditioning arguments are used to obtain the distributions and moments of the lengths of the interarrival periods other than the one containing this fixed time for the case of the time-homogeneous Poisson Process. Distributions of the waiting times for events that occur both before and after this fixed time are derived. This provides a fairly complete probabilistic …

Modeling And Fitting Two-Way Tables Containing Outliers, David L. Farnsworth

Articles

A model is proposed for two-way tables of measurement data containing outliers. The two independent variables are categorical and error free. Neither missing values nor replication are present. The model consists of the sum of a customary additive part that can be fit using least squares and a part that is composed of outliers. Recommendations are made for methods for identifying cells containing outliers and for fitting the model. A graph of the observations is used to determine the outliers’ locations. For all cells containing an outlier, replacement values are determined simultaneously using a classical missing-data tool. The result is …

Visual Literacy Of Molecular Biology Revealed Through A Card-Sorting Task, Dina L. Newman, Hannah Spector, Anna Neuenschwander, Anna J. Miller, Lauren Trumpore, Leslie Kate Wright

Articles

Visual literacy, which is the ability to effectively identify, interpret, evaluate, use, and create images and visual media, is an important aspect of science literacy. As molecular processes are not directly observable, researchers and educators rely on visual representations (e.g., drawings) to communicate ideas in biology. How learners interpret and organize those numerous diagrams is related to their underlying knowledge about biology and their skills in visual literacy. Furthermore, it is not always obvious how and why learners interpret diagrams in the way they do (especially if their interpretations are unexpected), as it is not possible to “see” inside the …

An Alternative To Hapke’S Macroscopic Roughness Correction, Dylan J. Shiltz, Charles M. Bachmann

Articles

In this paper, we present an alternative to Hapke’s correction for the photometric effect of macroscopic roughness of planetary surfaces (Hapke, 1984). Our model includes the effects of both single-facet scattering and multi-facet scattering. The single-facet scattering model is derived directly from the definition of bidirectional reflectance of a rough surface. We model projected shadowing by adopting an approximation published elsewhere in the literature. Monte Carlo simulations of single-facet scattering demonstrate very good agreement with the single-facet scattering component of our model. Using 3D printed molds with known roughness statistics, we prepared rough mineral surfaces consisting of quartz and olivine …

A Mathematical Model Of Juvenile Delinquency In The New York State, Oluwasegun Micheal Ibrahim

Articles

This report presents a mathematical model of juvenile delinquency in the New York State. In particular, we develop a juvenile delinquency system of non-linear differential equations using the mathematical epidemiology framework. In constructing this model, we assume that juvenile delinquency can be studied as a socially infectious disease. The stability of the juvenile delinquency-free equilibrium of the model is examined using the standard non-linear dynamical systems theory technique. We carried out a data fitting based on real-life data from the New York State Criminal Justice Services. The research result reveals that the formulated model conforms with the available data and …

Competitive Sustainability: The Intersection Of Sustainability And Business Success, Clyde Eiríkur Hull

Articles

Sustainability that beats the competition is different from sustainability that does not. Some who care very much about sustainability may not care at all about business success. However, they should. If businesses were to see that competitive sustainability leads to financial success, they would take it up and abandon nonsustainable practices

Enhancing The Wettability Of Polyetheretherketone (Peek) Membrane With Ozone For Improving Fuel Cell Performance, Hunter Heineman, Omran Omar, Benjamin Rippel, Ryan Keeley, Michael Mehan, Surendra K. Gupta, Gerald A. Takacs

Articles

Ozone was reacted with the aromatic membrane polyetheretherketone (PEEK) to form oxidized functional groups on the surface to enhance the attraction and transport of protons in fuel cells. Ozonation of unsaturated C-C sp2 bonds in PEEK formed a primary ozonide which dissociated to primarily produce O=C-O/O=C-OH moieties, and the root mean squared roughness factor (Rq) decreased from 7.4 nm, for the untreated sample, down to 3.1 nm. The oxidation of the surface and decrease in surface roughness made the surface increase in hydrophilicity as observed by the decrease in the water contact angle (CA) from 80.3° for untreated PEEK down …

Changes In Depressive Symptoms, Perceived Stres, And Food Security Among Study Participants With Metabolic Syndrome During A Covid-19-Mandated Research Pause, Barbara A. Lohse, Anahi Ramirez, Jenna Hickey, Lisa Bailey-Davis, Betty Drees, Kevin S. Masters, Elizabeth H. Ruder, Nicole Trabold

Introduction: This study explored how food security, perceived stress and mental health of persons with metabolic syndrome (MetS) changed in the COVID-19 pandemic.

Methods: An online survey was administered to persons enrolled in a 2-year lifestyle intervention trial to reverse metabolic syndrome at baseline; the survey was repeated during the COVID-19 pandemic. Outcomes were a change in depressive symptoms, perceived stress, and food security as measured by the Patient Health Questionnaire-8, Cohen Stress Scale, and USDA 10-item Food Security Screener. Changes in outcomes were analyzed with measures of association, paired t-test, repeated measures and independent t-test.

Results: Participants (n = …

Moving From Access To Inclusion By Making Communication A Priority, Sara Schley, Marchetti E. Carol

Articles

What does it mean to be a full participant in a faculty-student partnership? We tackled this question by considering disability identity and communication access as pivotal mindsets in facilitating not only pedagogical change in the college classroom, but also student transformation into change agents. Via a series of semester-long FLCs, we used a partnership model to develop strategies aimed at increasing interaction and inclusion in postsecondary courses (Schley et al., 2021). The student partners were all deaf or hard of hearing (DHH), with a diverse set of communication preferences. Faculty partners were also diverse: some were DHH though most were …

The …

One-Pot Synthesis Of N-Rich Porous Carbon For Efficient Co2 Adsorption Performance, Qiyun Yu, Jiali Bai, Muslum Demir, Bilge N. Altay, Xin Hu, Linlin Wang

Articles

N-enriched porous carbons have played an important part in CO2 adsorption application thanks to their abundant porosity, high stability and tailorable surface properties while still suffering from a non-efficient and high-cost synthesis method. Herein, a series of N-doped porous carbons were prepared by a facile one-pot KOH activating strategy from commercial urea formaldehyde resin (UF). The textural properties and nitrogen content of the N-doped carbons were carefully controlled by the activating temperature and KOH/UF mass ratios. As-prepared N-doped carbons show 3D block-shaped morphology, the BET surface area of up to 980 m2/g together with a pore volume of 0.52 cm3/g …

Making Sustainability A Core Competency: Consumer Response To Sustainable Innovative Products, Clyde Eiríkur Hull, Jennifer D. Russell, Monika Kukar-Kinney

Articles

Research suggests that sustainability may not be sufficient to yield a competitive advantage. Building on the resource-based view, this research evaluates three questions: (1) Can using sustainability as a differentiator lead to consumers choosing sustainable products? (2) Does product sustainability appeal more to environmentally concerned consumers? (3) Does product sustainability appeal more when paired with innovation? To test the hypotheses, an online survey of 344 US respondents was conducted. Consumers were given a hypothetical budget for an office chair and asked to choose between two products at a time. Hypotheses were tested with frequency and Chisquare tests and logistic regression. …

Visual Attention For Linguistic And Non-Linguistic Body Actions In Non-Signing And Native Signing Children, Rain G. Bosworth, So One Hwang, David P. Corina

Articles

Evidence from adult studies of deaf signers supports the dissociation between neural systems involved in processing visual linguistic and non-linguistic body actions. The question of how and when this specialization arises is poorly understood. Visual attention to these forms is likely to change with age and be affected by prior language experience. The present study used eye-tracking methodology with infants and children as they freely viewed alternating video sequences of lexical American sign language (ASL) signs and non-linguistic body actions (self-directed grooming action and objectdirected pantomime). In Experiment 1, we quantified fixation patterns using an area of interest (AOI) approach …

Comprehensive Evidence Implies A Higher Social Cost Of Co2, Kevin Rennert, Frank Errickson, Brian C. Prest, Lisa Rennels, Richard G. Newell, William Pizer, Cora Kingdon, Jordan Wingenroth, Roger Cooke, Bryan Parthum, David Smith, Kevin Cromar, Delavane Diaz, Frances C. Moore, Ulrich K. Müller, Richard J. Plevin, Adrian E. Raftery, Hana Ševčíková, Hannah Sheets, James H. Stock, Tammy Tan, Mark Watson, Tony E. Wong, David Anthoff

Articles

The social cost of carbon dioxide (SC-CO2) measures the monetized value of the damages to society caused by an incremental metric tonne of CO2 emissions and is a key metric informing climate policy. Used by governments and other decision-makers in beneft–cost analysis for over a decade, SC-CO2 estimates draw on climate science, economics, demography and other disciplines. However, a 2017 report by the US National Academies of Sciences, Engineering, and Medicine1 (NASEM) highlighted that current SC-CO2 estimates no longer refect the latest research. The report provided a series of recommendations for improving the scientifc basis, transparency and uncertainty characterization of …

Mimibrick.Jl: A Julia Package For The Brick Model For Sea-Level Change In The Mimi Integrated Modeling Framework, Tony E. Wong, Lisa Rennels, Vivek Srikrishnan, Alexander Bakker, Klaus Keller, David Anthoff

Articles

BRICK is a semi-empirical model for global and local mean sea-level change (Wong et al., 2017). The core model includes component sub-models for the major contributors to global mean sea-level change - glaciers and ice caps, thermal expansion, land water storage, and the Greenland and Antarctic ice sheets. The resulting global mean sea levels can be downscaled via a data set that represents the “fingerprint” of each sea-level component on local mean sea level (Slangen et al., 2014). In this way, BRICK provides information about local sea-level changes, including characterizations of key uncertainties. BRICK is flexible and efficient enough to …

Prevalence And Incidence Of Nonmotor Symptoms In Individuals With And Without Parkinson’S Disease, Mariam Paracha, Konnor Herbst, Karl Kieburtz, Charles S. Venuto

Articles

Background

The prevalence ratio (PR) and incidence rate ratio (IRR) of nonmotor symptoms (NMS) were calculated for early Parkinson's disease (PD) versus non-PD from 2 observational studies.

Methods

NMS were assessed through the self-reported Non-Motor Symptom Questionnaire in the online Fox Insight study and through self- and clinician-rated scales in the Parkinson's Progression Marker Initiative (PPMI) study. Age- and sex-adjusted/matched PR and IRR were estimated for each NMS by PD status using Poisson regression.

Results

Most NMS occurred more frequently in PD. Among 15,194 Fox Insight participants, sexual dysfunction had the largest adjusted PR (12.4 [95% CI, 6.9–22.2]) and dysgeusia/hyposmia …

“It's So Normal, And … Meaningful.” Playing With Narrative, Artifacts, And Cultural Difference In Florence, Dheepa Sundaram, Owen Gottlieb

Articles

This article considers how player interactions with religious and ethnic markers, create

a globalized game space in the mobile game Florence (2018). Florence is a multiaward-

winning interactive novella game with story-integrated minigames that weave

play experiences into the narrative. The game, in part, explores love, loss, and

rejuvenation as relatable experiences. Simultaneously, the game produces a unique

experience for each player, as they can refract the game narrative through their own

cultural, identitarian lens. The game assumes the shared cultural space of the player,

the player-character (PC), and the non-player-character (NPC) while blurring the

boundaries between each of these …

Uncovering Inclusivity Gaps In Design Pedagogy Through The Digital Design Marginalization Framework, Jaisie Sin, Cosmin Munteanu, Michael Nixon, Velian Pandeliev, Garreth W. Tigwell, Kristen Shinohara, Anthony Tang, Steve Szigeti

Articles

Designers play a key role in the design of inclusive and socially conscious interfaces. Thus, it is imperative for designers to be thoughtful of the ethical and social implications of design. However, gaps in the foundational training that designers receive (e.g., as university students) can negatively impact their ability to consider the social implications of their design practice. This can result in consequences such as digital marginalization, which, as defined by the Digital Design Marginalization (DDM) framework, is the “pushing away”, whether intentional or not, of a defined group of users from a digital or online service or system, where …

Understanding Color Associations And Their Effects On Expectations Of Drugs’ Efficacies, Rema M. Amawi, Michael J. Murdoch

Articles

Colors influence our daily perceptions and expectations that manifest in a variety of ways. This research has three main objectives: to demonstrate the relationship between the colors of pills and their expected efficacies, to test this effect on a wide variety of demographics, thereby demonstrating their influence on choices made by participants. Finally, to understand the reasoning behind the choices made by participants, and the color associations exhibited. The results of a series of surveys showed clear similarities and differences across various demographics. The strongest and most consistent color associations were those of white with pain relief and red with …

The Dna Landscape: Development And Application Of A New Framework For Visual Communication About Dna, Leslie Kate Wright, Emalee Wrightstone, Lauren Trumpore, Julia Steele, Deanna M. Abid, Dina L. Newman

Articles

Learning molecular biology involves using visual representations to communicate ideas about largely unobservable biological processes and molecules. Genes and gene expression cannot be directly visualized, but students are expected to learn and understand these and related concepts. Theoretically, textbook illustrations should help learners master such concepts, but how are genes and other DNA-linked concepts illustrated for learners? We examined all DNA-related images found in 12 undergraduate biology textbooks to better understand what biology students encounter when learning concepts related to DNA. Our analysis revealed a wide array of DNA images that were used to design a new visual framework, the …

Kf-Loc: A Kalman Filter And Machine Learning Integrated Localization System Using Consumer-Grade Millimeter-Wave Hardware, Abhishek Vashist, Maojia Li, Amlan Ganguly, Sai Manoj P. D., Clark Hochgraf, Raymond Ptucha, Andres Kwasinski, Michael E. Kuhl

Articles

With the ever-increasing demands of e-commerce, the need for smarter warehousing is increasing exponentially. Such warehouses requires industry automation beyond Industry 4.0. In this work, we use consumer-grade millimeter-wave (mmWave) equipment to enable fast, and low-cost implementation of our localization system. However, the consumer-grade mmWave routers suffer from coarse-grained channel state information due to cost-effective antenna array design limiting the accuracy of localization systems. To address these challenges, we present a Machine Learning (ML) and Kalman Filter (KF) integrated localization system (KF-Loc). The ML model learns the complex wireless features for predicting the static position of the robot. When in …
