Estimating Abundance Of An Elusive Cetacean In A Complex Environment: Harbor Porpoises (Phocoena Phocoena) In Inland Waters Of Southeast Alaska, Alexandre N. Zerbini, Kimberly T. Goetz, Karin A. Forney, Charlotte Boyd

Faculty Research, Scholarly, and Creative Activity

The harbor porpoise (Phocoena phocoena) is common in temperate waters of the eastern North Pacific Ocean, including Southeast Alaska inland waters, a complex environment comprised of open waterways, narrow channels, and inlets. Two demographically independent populations are currently recognized in this region. Bycatch of porpoises in the salmon drift gillnet fisheries is suspected to occur regularly. In this study, we apply distance sampling to estimate abundance of harbor porpoise during ship surveys carried out in the summer of 2019. A stratified survey design was implemented to sample different harbor porpoise habitats. Survey tracklines were allocated following a randomized survey design …

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 …

Comparison Of Qt And Qtc Interval Measurements From Bedside Electrocardiograms Between Expert Nurses, Bedside Nurses, And Computerized Measurements: A Pilot Study, Karolina Ho

Theses

Prolongation of the QT/QTc (heart rate corrected) >500 milliseconds (msec) measured on the electrocardiogram (ECG) in hospitalized patients is associated with torsade de pointes (TdP). While some bedside ECG monitors now offer continuous QT/QTc software, agreement of these measurements to bedside and/or expert nurses has not been evaluated. The purpose of this study was to compare QT/QTc measurements between expert nurses, bedside nurses, both using electronic calipers, and continuous computerized measurements.

Xcvatr: Detection And Characterization Of Variant Impact On The Embeddings Of Single -Cell And Bulk Rna-Sequencing Samples, Arif Harmanci, Akdes Serin Harmanci, Tiemo J Klisch, Akash J Patel

Duncan NRI Faculty and Staff Publications

Background: RNA-sequencing has become a standard tool for analyzing gene activity in bulk samples and at the single-cell level. By increasing sample sizes and cell counts, this technique can uncover substantial information about cellular transcriptional states. Beyond quantification of gene expression, RNA-seq can be used for detecting variants, including single nucleotide polymorphisms, small insertions/deletions, and larger variants, such as copy number variants. Notably, joint analysis of variants with cellular transcriptional states may provide insights into the impact of mutations, especially for complex and heterogeneous samples. However, this analysis is often challenging due to a prohibitively high number of variants and …

Cardiac Physical Exam Skills And Auscultation Session For Pediatric Interns, Christopher A Sumski, Anoop Singh, Amanda Rogers, Robert Treat, Charles Bergstrom

2020-Current year OA Pubs

INTRODUCTION: Physicians need adequate physical exam skills. Unfortunately, interns have variable physical exam skills, and teaching is often limited to rounds, an inconsistent setting. Physical exam skills, particularly those involving auscultation, require practice. Our goal was to create a cardiac physical exam workshop for pediatric interns that would improve their performance on an interactive assessment of their ability and understanding in physical exam and murmur interpretation.

METHODS: We completed a targeted needs assessment and then developed a 2-hour workshop on the pediatric cardiac physical exam targeted to pediatrics residents. The workshop included didactics, group discussion, and practice interpreting common pediatric …

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

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, …

Taking Chardin's Kitchen Maids Seriously, Danielle Ezor

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

Historically, Jean-Siméon Chardin’s The Kitchen Maid and Return from the Market have been characterized as austere images of middle-class virtue. However, the engravings made after these paintings include verses that place the paintings within the satirical tradition. Thus, there is a misalignment between the canonical interpretation of Chardin’s kitchen maids as virtuous and the satirical understanding of these paintings. I reconcile these two contradictory interpretations by offering a feminist reinterpretation of Chardin’s The Kitchen Maid and Return from the Market, juxtaposing the prints and their satirical verses and considering the female viewer. In my analysis, I focus on small, …

Hannah Humphrey, London’S Leading Caricature Printseller, Ersy Contogouris, Béatrice Denis

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

Hannah Humphrey (ca. 1745-1818) was the exclusive publisher of James Gillray's (1756-1815) caricatures from 1791 until Gillray's death. His achievements were made possible in large part thanks to Humphrey and her innovative business acumen. But while Gillray has been celebrated and studied by art historians, Humphrey’s contribution to his success and to the history of graphic satire has remained unexamined. This article is a first attempt to shift the focus onto her in the story of the “golden age” of British caricature. It outlines Humphrey’s career, takes a closer look at her relationship with Gillray, and finally considers some of …

Xr In Aviation Training: Insight From Academia, Industry, And Non-Profit Institutions, Stephanie G. Fussell, Robert L. Thomas, Bejamin Kwasa, James Birdsong, Kurt Reesman, Lori Brow, Joel Scharlat, William T. Ballo

National Training Aircraft Symposium (NTAS)

The COVID-19 pandemic had a profound impact on education and training. Institutions that relied heavily on face-to-face instruction suddenly needed alternative modalities to keep students on course, forcing educators and trainers to employ a variety of educational techniques via technologies that they may not have had experience with. This shift has brought the advantages – and disadvantages – of augmented, mixed, and virtual reality technologies (collectively, extended reality or XR) for education and training into sharp focus. Programs were quickly assembled, and not always with consideration of learning theories. As learning and training were resumed in in-person settings, academics and …

Processing crude oil of variable composition, especially due to the need to process crude oil blends obtained from various sources, presents a tremendous process challenge. This is mainly due to the destabilization of the colloidal system manifested mostly by the precipitation of the asphaltene fraction. The precipitation of asphaltenes from crude oil is a serious problem during extraction, transport, and processing. In the latter case, engineers and scientists have spent a lot of time determining what mechanisms are conducive to the occurrence of this phenomenon. On the one hand, there was a scientific curiosity about the principles of the nanoworld …

Prostitution And The Contagious Diseases Acts In Nineteenth-Century England, Victoria Knox

Honors Program Theses and Projects

During England’s Victorian period, the Contagious Diseases Acts were established, which regulated women’s bodies and represented the intersectionality of gender, class, and power. Before the CD Acts, England began to grow rapidly during the Industrial Revolution, which was in part made possible by the work of underpaid and undervalued working-class women. One option for women to earn an income was prostitution. Men who worked as sailors and soldiers were common customers in prostitution, which contributed to the rapid spread of venereal disease throughout the British Empire. In the spirit of protecting men, the first CD Acts were passed in the …
