Phase-Averaged, Frequency Dependence Of Jet Dynamics In A Scaled Up Vocal Fold Model With Full And Incomplete Closure, Nathaniel Wei, Abigail Haworth, Hunter Ringenberg, Michael Krane, Timothy Wei

Department of Mechanical and Materials Engineering: Faculty Publications

This study focuses on frequency dependence effects on glottal jet dynamics with a focus on the physiological condition in which the vocal folds do not fully close. Incomplete closure occurs naturally in children and adult females. But there are also pathological conditions that can be problematic. Experiments were conducted using a 10× scaled-up model in a free surface water tunnel. Two-dimensional vocal fold models with semicircular medial surfaces were stepper motor driven inside a square duct with constant opening and closing speeds. Cases with complete vocal fold closure and incomplete closure to only 15% of the maximum gap were examined. …

Does Receiving A Sars-Cov-2 Antibody Test Result Change Covid-19 Protective Behaviors? Testing Risk Compensation In Undergraduate Students With A Randomized Controlled Trial, Christina Ludema, Molly S Rosenberg, Jonathan T Macy, Sina Kianersi, Maya Luetke, Chen Chen, Lilian Golzarri-Arroyo, Erin Ables, Kevin Maki, David B Allison

Children’s Nutrition Research Center Staff Publications

Background: Risk compensation, or matching behavior to a perceived level of acceptable risk, can blunt the effectiveness of public health interventions. One area of possible risk compensation during the SARS-CoV-2 pandemic is antibody testing. While antibody tests are imperfect measures of immunity, results may influence risk perception and individual preventive actions. We conducted a randomized control trial to assess whether receiving antibody test results changed SARS-CoV-2 protective behaviors.

Purpose: Assess whether objective information about antibody status, particularly for those who are antibody negative and likely still susceptible to SARS-CoV-2 infection, increases protective behaviors. Secondarily, assess whether a positive antibody test …

Relative Importance Of Radar Variables For Nowcasting Heavy Rainfall: A Machine Learning Approach, Yi Victor Wang, Seung Hee Kim, Geunsu Lyu, Choeng-Lyong Lee, Gyuwon Lee, Ki-Hong Min, Menas C. Kafatos

Institute for ECHO Articles and Research

Highly short-term forecasting, or nowcasting, of heavy rainfall due to rapidly evolving mesoscale convective systems (MCSs) is particularly challenging for traditional numerical weather prediction models. To overcome such a challenge, a growing number of studies have shown significant advantages of using machine learning (ML) modeling techniques with remote sensing data, especially weather radar data, for high-resolution rainfall nowcasting. To improve ML model performance, it is essential first and foremost to quantify the importance of radar variables and identify pertinent predictors of rainfall that can also be associated with domain knowledge. In this study, a set of MCS types consisting of …

A Unique High-Output Cardiac Hypertrophy Phenotype Arising From Low Systemic Vascular Resistance In Cantu Syndrome, Gautam K Singh, Conor Mcclenaghan, Manish Aggarwal, Hongjie Gu, Maria S Remedi, Dorothy K Grange, Colin G Nichols

2020-Current year OA Pubs

Background Cardiomegaly caused by left ventricular hypertrophy is a risk factor for development of congestive heart failure, classically associated with decreased systolic and/or diastolic ventricular function. Less attention has been given to the phenotype of left ventricular hypertrophy with enhanced ventricular function and increased cardiac output, which is potentially associated with high-output heart failure. Lack of recognition may pose diagnostic ambiguity and management complexities. Methods and Results We sought to systematically characterize high-output cardiac hypertrophy in subjects with Cantu syndrome (CS), caused by gain-of-function variants in

Structural Insights Into Cardiolipin Replacement By Phosphatidylglycerol In A Cardiolipin-Lacking Yeast Respiratory Supercomplex, John L Spudich

Faculty, Staff and Student Publications

Potassium-selective channelrhodopsins (KCRs) are light-gated K+ channels recently found in the stramenopile protist Hyphochytrium catenoides. When expressed in neurons, KCRs enable high-precision optical inhibition of spiking (optogenetic silencing). KCRs are capable of discriminating K+ from Na+ without the conventional K+ selectivity filter found in classical K+ channels. The genome of H. catenoides also encodes a third paralog that is more permeable for Na+ than for K+. To identify structural motifs responsible for the unusual K+ selectivity of KCRs, we systematically analyzed a series of chimeras and mutants of this protein. We found that mutations of three critical residues in the …

Ivf So White, So Medical: Digital Normativity And Algorithm Bias In Infertility On Instagram, Caitlyn M. Jarvis, Margaret M. Quinlan

Human-Machine Communication

Increasingly, women experiencing infertility are turning online to social media platforms, like Instagram, to engage with a support network and foster empathy. However, Instagram is also noted for its augmentation of White, cis, and heteronormative femininity through a process of silencing and minoritizing alternative, non-White voices. Through an inductive analysis of the most frequently used infertility hashtags, we collected and analyzed 252 Instagram posts to investigate how these algorithmic practices may socially construct the idealized IVF experience through communicating normative expectations. We identify predominant patterns of use that reinforce stratification within infertility treatments as primarily accessible to White women and …

Designing A Loving Robot: A Social Construction Analysis Of A Sex Robot Creator’S Vision, Annette Masterson

Human-Machine Communication

In 2018, one of the world’s first sex robots was released by CEO Matt McMullen and his company, RealDoll. With artificial intelligence capabilities, the Harmony model is meant to support and converse with users. Using a social construction of technology theory lens, this study develops the theory’s fourth level of analysis, emphasizing mass media’s construction abilities. A critical discourse analysis of 38 publicity interviews found a tendency to emphasize the companionship of sex robots while envisioning a future where integration is normalized, and a sentient robot is possible.

Do People Perceive Alexa As Gendered? A Cross-Cultural Study Of People’S Perceptions, Expectations, And Desires Of Alexa, Leopoldina Fortunati, Autumn P. Edwards, Anna Maria Manganelli, Chad Edwards, Federico De Luca

Human-Machine Communication

Mainly, the scholarly debate on Alexa has focused on sexist/anti-woman gender representations in the everyday life of many families, on a cluster of themes such as privacy, insecurity, and trust, and on the world of education and health. This paper takes another stance and explores via online survey methodology how university student respondents in two countries (the United States, n = 333; and Italy, n = 322) perceive Alexa’s image and gender, what they expect from this voice-based assistant, and how they would like Alexa to be. Results of a free association exercise showed that Alexa’s image was scarcely embodied …

Gender Ambiguity In Voice-Based Assistants: Gender Perception And Influences Of Context, Sandra Mooshammer, Katrin Etzrodt

Human-Machine Communication

Recently emerging synthetic acoustically gender-ambiguous voices could contribute to dissolving the still prevailing genderism. Yet, are we indeed perceiving these voices as “unassignable”? Or are we trying to assimilate them into existing genders? To investigate the perceived ambiguity, we conducted an explorative 3 (male, female, ambiguous voice) × 3 (male, female, ambiguous topic) experiment. We found that, although participants perceived the gender-ambiguous voice as ambiguous, they used a profoundly wide range of the scale, indicating tendencies toward a gender. We uncovered a mild dissolve of gender roles. Neither the listener’s gender nor the personal gender stereotypes impacted the perception. However, …

Gender And Human-Machine Communication: Where Are We?, Leopoldina Fortunati, Autumn P. Edwards

Human-Machine Communication

In this introduction to the fifth volume of the journal Human-Machine Communication, we present and discuss the five articles focusing on gender and human-machine communication. In this essay, we will analyze the theme of gender, including how this notion has historically and politically been set up, and for what reasons. We will start by considering gender in in-person communication, then we will progress to consider what happens to gender when it is mediated by the most important ICTs that preceded HMC: the telephone, mobile phone, and computer-mediated communication (CMC). We outline the historical framework necessary to analyze the last section …

Physical Activity Independently Predicts Perceived Stress During The Covid-19 Pandemic In Private University Students, Curtis W. Brownell, Laura S. Kabiri, Cassandra S. Diep, Heidi Y. Perkins, Amanda M. Perkins-Ball, Augusto X. Rodriguez

International Journal of Exercise Science

International Journal of Exercise Science 15(7): 1680-1691, 2022. Physical activity has significantly declined during the COVID-19 pandemic. Declines in physical activity have correlated with increased levels of perceived stress, though studies examining physical activity and stress have failed to account for critical confounds. The present study aims to determine whether physical activity independently predicts perceived stress in students attending private four-year universities. Physical activity, socioeconomic status, resilience, gender, and perceived stress data were collected from 85 students and used in a multiple linear regression analysis. The regression model accounted for 43.5% of the variance in perceived stress (R2 = .462, …

Ripped From The Headlines: Teaching Lady Mary Wortley Montagu's Turkish Letters In The Context Of 21st-Century Controversies, Susan Spencer

ABO: Interactive Journal for Women in the Arts, 1640–1830

In the long shadow of 9/11 and the ongoing COVID pandemic, Lady Mary Wortley Montagu’s Turkish Embassy Letters connect with the lived experience of today’s students, especially the cluster of eight letters dated 1 April 1717. By emphasizing parallels between Montagu’s observations and the students’ own lives, The Turkish Embassy Letters can add a modern dimension to the eighteenth century in general, challenges of gender, and texts written in and about the Muslim world.

Teaching Eliza Fay's Original Letters From India (1817) Through Classroom Editing, Lacy Marschalk

ABO: Interactive Journal for Women in the Arts, 1640–1830

Travel writing is an ever-growing area of interest in eighteenth-century studies, but it can be difficult to teach. Students often find the writing dry and unrelatable, and faculty who have had little experience with travel writing in their own educations may not know which texts would prove useful to their courses. In this article, I discuss the travel narrative with which I've found the most pedagogical success, Eliza Fay's Original Letters from India (1817). Fay's initial journey to India includes a range of captivating adventures, including encounters with Marie Antoinette in Paris, bandits in Egypt, and Hyder Ali in Calicut, …

Cooking Up Knowledge: Materiality, Recipes, And Jane Barker’S A Patch-Work Screen For The Ladies, Carolin Boettcher

ABO: Interactive Journal for Women in the Arts, 1640–1830

The recipes included in Jane Barker’s A Patch-Work Screen for the Ladies (1723) appear to be some of the most jarring and out-of-context inclusions in the narrative. This article explores the relationship between Barker’s novel and the form of the recipe collection in the late seventeenth and early eighteenth centuries on both a material and an epistemological level. The entanglements between recipes and the patchwork screen not only point to the processes of constructing and conveying knowledge, but also to the materiality of these processes as Galesia and the Lady build the patchwork screen. Her focus on the materiality of …

Postures After The Antique In Eighteenth-Century Portraits Of Women, Lauren K. Disalvo

ABO: Interactive Journal for Women in the Arts, 1640–1830

This paper re-examines the relationship between eighteenth-century portraiture and the antique where women adopt the postures of floating female figures from Pompeiian wall paintings in eighteenth-century portraiture. I argue that eighteenth-century floating portraits afforded their female sitters an opportunity to assert classical knowledge while adhering to typical conventions of femininity.

Can Electricity Liberalisation Foster The Development Of Radical Clean-Energy Technologies?, Matteo Romagnoli

Fondazione Eni Enrico Mattei Working Papers

The paper investigates the effect of electricity liberalisation on the variety of clean energy patent’ search space to asses whether a more competitive electricity market can foster the development of radical clean-energy technologies. This idea is tested using a cross-section of patents filed in the period 1990-2017, a set of patent-level indicators and an instrumental variable approach. Results show that electricity liberalisation pushes clean-energy patents to cite knowledge from technological fields other than their own. However, the reform does not significantly affect the overall breath of the knowledge base of these patents. Additional insights are drawn by looking at the …
