Additionally, research on the public attention to COVID-19 as reflected through frames on social media is scarce.

Objective: This study identified the frames about the COVID-19 pandemic in the public discourse on Twitter, which voices diverse opinions. This study also investigated the amount of public attention to those frames on Twitter.

Methods: We collected 22 trending hashtags related to COVID-19 in the United States and 694,582 tweets written in English containing these …

Toward A Methodology For Evaluating Dna Variants In Nuclear Families, Dustin B. Miller, Reid Robison, Stephen Piccolo

Faculty Publications

The genetic underpinnings of most pediatric-cancer cases are unknown. Population-based studies use large sample sizes but have accounted for only a small proportion of the estimated heritability of pediatric cancers. Pedigree-based studies are infeasible for most human populations. One alternative is to collect genetic data from a single nuclear family and use inheritance patterns within the family to filter candidate variants. This approach can be applied to common and rare variants, including those that are private to a given family or to an affected individual. We evaluated this approach using genetic data from three nuclear families with 5, 4, and …

Massive Open Online Courses For Professional Certificate Programs? Perspectives On Professional Learners’ Longitudinal Participation Patterns, Hengtao Tang Ph.D., Wanli Xing

Faculty Publications

Massive open online courses (MOOCs) have been integrated into higher education systems as an option for delivering online professional degree and certificate programs; however, concerns about whether employed professionals actively participate in MOOCs remain unresolved. Some researchers have described learners’ employment as the major cause of attrition from MOOCs, but research has not addressed how employed learners interact with MOOCs over time. Understanding employed professionals’ trajectory of participation patterns across course time is thus essential to improving the effectiveness of MOOCs. This study investigated the log data of learner participation to explore how attrition occurs in a professional MOOC, focusing …

The Individual Water Insecurity Experiences (Iwise) Scale: Reliability, Equivalence And Validity Of An Individual-Level Measure Of Water Security, Sera L. Young, Hilary J. Bethancourt, Zacchary R. Ritter, Edward A. Frongillo Jr.

Faculty Publications

Objective: The lack of a validated and cross-culturally equivalent scale for measuring individual-level water insecurity has prevented identification of those most vulnerable to it. Therefore, we developed the 12-item Individual Water InSecurity Experiences (IWISE) Scale to comparably measure individual experiences with access, use, and stability (reliability) of water. Here, we examine the reliability, cross-country equivalence, and cross-country and within-country validity of the scale in a cross-sectional sample.

Methods: IWISE items were implemented by the Gallup World Poll among nationally representative samples of 43 970 adults (15 y) in 31 low-income and middle-income countries (LMICs). Internal consistency was assessed …

Trajectories Of Heart Activity Across Infancy To Early Childhood Differentially Predict Autism And Anxiety Symptoms In Fragile X Syndrome, Abigail Hogan Ph.D., Erin Hunt, Kayla Smith, Conner Black, Katherine Bangert, Jessica Klusek Ph.D., Ccc-Slp, Jane Roberts

Faculty Publications

Fragile X syndrome (FXS) is a monogenic disorder characterized by high rates of autism spectrum disorder (ASD) and anxiety. A longstanding "hyperarousal hypothesis" in FXS has argued that ANS dysfunction underpins many symptoms of FXS. However, the developmental onset and trajectory of ANS dysfunction, as well as the consequences of ANS dysfunction on later psychiatric symptoms, remain poorly understood in FXS. Insight into the emergence, trajectory, and consequences of ANS dysfunction across early development in FXS has critical implications for prevention, intervention, and optimal outcomes in both typical and atypical development. This longitudinal study investigated whether and when males with …

On The Need To Determine Accurately The Impact Of Higher-Order Sensitivities On Model Sensitivity Analysis, Uncertainty Quantification And Best-Estimate Predictions, Dan Gabriel Cacuci

Faculty Publications

This work aims at underscoring the need for the accurate quantification of the sensitivities (i.e., functional derivatives) of the results (a.k.a. “responses”) produced by large-scale computational models with respect to the models’ parameters, which are seldom known perfectly in practice. The large impact that can arise from sensitivities of order higher than first has been highlighted by the results of a third-order sensitivity and uncertainty analysis of an OECD/NEA reactor physics benchmark, which will be briefly reviewed in this work to underscore that neglecting the higher-order sensitivities causes substantial errors in predicting the expectation and variance of model responses. The …

Fatal Police Violence By Race And State In The Usa, 1980–2019: A Network Meta-Regression, Fablina Sharara, Eve E. Wool, Gregory J. Bertolacci, Nicole Davis Weaver, Shelley Balassyano, Ismaeel Yunusa Ph. D., Et Al.

Faculty Publications

Background

The burden of fatal police violence is an urgent public health crisis in the USA. Mounting evidence shows that deaths at the hands of the police disproportionately impact people of certain races and ethnicities, pointing to systemic racism in policing. Recent high-profile killings by police in the USA have prompted calls for more extensive and public data reporting on police violence. This study examines the presence and extent of under-reporting of police violence in US Government-run vital registration data, offers a method for correcting under-reporting in these datasets, and presents revised estimates of deaths due to police violence in …

A Polynomial Roth Theorem For Corners In Finite Fields, Rui Han, Michael T. Lacey, Fan Yang

Faculty Publications

We prove a Roth-type theorem for polynomial corners in the finite field setting. Let ϕ1 and ϕ2 be two polynomials of distinct degree. For sufficiently large primes p, any subset (Formula presented.) with (Formula presented.) contains three points (Formula presented.). The study of these questions on (Formula presented.) was started by Bourgain and Chang. Our Theorem adapts the argument of Dong, Li, and Sawin, in particular relying upon deep Weil-type inequalities established by N. Katz.

The Inverse Problem For A Spectral Asymmetry Function Of The Schrödinger Operator On A Finite Interval, B. Malcolm Brown, Karl Michael Schmidt, Stephen P. Shipman, Ian Wood

Faculty Publications

For the Schrödinger equation (Formula presented.) on a finite x-interval, there is defined an “asymmetry function” (Formula presented.), which is entire of order 1/2 and type 1 in λ. Our main result identifies the classes of square-integrable potentials (Formula presented.) that possess a common asymmetry function (Formula presented.). For any given (Formula presented.), there is one potential for each Dirichlet spectral sequence.

Biblical Hermeneutical Principles Dealing With Race, Racism And Social Justice Issues, Jiří Moskala

Faculty Publications

Many modern problems arise from the misinterpretation of the Bible, unfortunately. One of my best Church History teachers Amadeo Molnár at the Protestant Faculty in Prague told us: “The history of the Christian Church is the history of the interpretation of the Bible.” At first, I doubted this statement’s truth, but after some reflections, I understood. Divisions were created and wars were fought because of certain dogmas, and millions were tortured, killed, or enslaved due to specific ideologies and wrong belief systems by believers. So many atrocities were committed in the name of God!

Robust Projections Of Future Fire Probability For The Conterminous United States, Peng Gao, Adam J. Terando, John A. Kupfer, J. Morgan Varner, Michael C. Stambaugh, Ting L. Lei, J. Kevin Hiers

Faculty Publications

Globally increasing wildfires have been attributed to anthropogenic climate change. However, providing decision makers with a clear understanding of how future planetary warming could affect fire regimes is complicated by confounding land use factors that influence wildfire and by uncertainty associated with model simulations of climate change. We use an ensemble of statistically downscaled Global Climate Models in combination with the Physical Chemistry Fire Frequency Model (PC2FM) to project changing potential fire probabilities in the conterminous United States for two scenarios representing lower (RCP 4.5) and higher (RCP 8.5) greenhouse gas emission futures. PC2FM is a physically-based and scale-independent model …

High-Order Deterministic Sensitivity Analysis And Uncertainty Quantification: Review And New Developments, Dan Gabriel Cacuci

Faculty Publications

This work reviews the state-of-the-art methodologies for the deterministic sensitivity analysis of nonlinear systems and deterministic quantification of uncertainties induced in model responses by uncertainties in the model parameters. The need for computing high-order sensitivities is underscored by presenting an analytically solvable model of neutron scattering in a hydrogenous medium, for which all of the response’s relative sensitivities have the same absolute value of unity. It is shown that the wider the distribution of model parameters, the higher the order of sensitivities needed to achieve a desired level of accuracy in representing the response and in computing the response’s expectation, …

Leveraging Collaboration And Peer Support To Initiate And Sustain A Faculty Development Program, Anneris Coria-Navia, Scott Moncrieff

Faculty Publications

In today’s impoverished higher education fiscal climate, especially considering the enormous financial implications to higher education of accommodating the changes required by the coronavirus pandemic, “nonessential” though highly important programs, such as centers for teaching and learning (CTLs), are very likely to be underfunded. In this study, we illustrate how underfunded programs can leverage peer collaboration and support to initiate productive, formal systems of assistance for faculty by describing a number of such programs developed by and/or coordinated by our CTL. Moreover, we propose that sustainable programs, especially at small liberal arts institutions, must include a strong component of peer …

The Impact Of Separate Opinions On International Criminal Law, Nancy Amoury Combs

Faculty Publications

Dissents have had a tumultuous history in national and international courts throughout the world. Initially reviled, dissents have come to be a well-accepted, even praiseworthy, component of the American judicial system, and they have traversed the same trajectory in other countries as well as in international courts and tribunals. Particularly noteworthy among international courts are those created to prosecute perpetrators of mass atrocities, such as genocide, crimes against humanity, and war crimes. And nowhere are dissents more common than in these mass atrocity courts. Yet, as prevalent as these dissents are, they have received virtually no scholarly or practical attention. …

Fe-Catalyzed Sulfide Oxidation In Hydrothermal Plumes Is A Source Of Reactive Oxygen Species To The Ocean, Timothy J. Shaw, George W. Luther Iii, Richard Rosas, Véronique E. Oldham, Nicole R. Coffey, John L. Ferry, Dewamunnage M. C. Dias, Mustafa Yücel, Aubin Thibault De Chanvalon

Faculty Publications

Historically, the production of reactive oxygen species (ROS) in the ocean has been attributed to photochemical and biochemical reactions. However, hydrothermal vents emit globally significant inventories of reduced Fe and S species that should react rapidly with oxygen in bottom water and serve as a heretofore unmeasured source of ROS. Here, we show that the Fe-catalyzed oxidation of reduced sulfur species in hydrothermal vent plumes in the deep oceans supported the abiotic formation of ROS at concentrations 20 to 100 times higher than the average for photoproduced ROS in surface waters. ROS (measured as hydrogen peroxide) were determined in hydrothermal …
