Addressing Structural Racism In The Health Workforce, Randl B. Dent, Anushree Vichare, Jaileessa Casimir

Publications and Research

One of the greatest challenges facing the United States are health inequities among racial/ethnic and other marginalized populations. The deep-rooted structural racism embedded in our social systems, including our health care system and health workforce, is a core cause of racial health inequities. 1 Among many definitions of institutionalized or structural racism, Dr Jones 2 best defines it as: “Differential access to goods, services and opportunities of society by race ... It is structural, having been codified in our institutions of custom, practice, and law, so there need not be an identifiable perpetrator.” Dr Jones further explains that to set …

A Conserved Structural Role For The Walker-A Lysine In P-Loop Containing Kinases, Fatlum Hajredini, Ranajeet Ghose

Publications and Research

Bacterial tyrosine kinases (BY-kinases) and shikimate kinases (SKs) comprise two structurally divergent P-loop containing enzyme families that share similar catalytic site geometries, most notably with respect to their Walker-A, Walker-B, and DxD motifs. We had previously demonstrated that in BY-kinases, a specific interaction between the Walker-A and Walker-B motifs, driven by the conserved “catalytic” lysine housed on the former, leads to a conformation that is unable to efficiently coordinate Mg²⁺•ATP and is therefore incapable of chemistry. Here, using enhanced sampling molecular dynamics simulations, we demonstrate that structurally similar interactions between the Walker-A and Walker-B motifs, also mediated by …

"Writing Unspeakable Things: Speechlessness, Abjection, And The Ethics/Aesthetics Of (Not) Representing Sexual Violence In Three Korean American "Comfort Women' Novels", M Laura Barberan Reinares

Publications and Research

This article analyzes “comfort women” novels by the Korean American authors Therese Park, Nora Okja Keller, and Chang-rae Lee in terms of the ethics and aesthetics of representing sexual violence through language. I specifically look at these authors’ stylistic strategies to describe rape in writing and how they (more or less successfully) avoid voyeuristic portrayals of the “comfort women” by controlling the narrative point of view and relying on traumatic “speechlessness” and abjection. Building on relevant notions from the fields of photography, cinematography, philosophy, and psychoanalysis, this analysis suggests that in-progress representations of rape in language become a futile project …

Building A Feminist Commons In The Time Of Covid-19, Miriam Ticktin

Publications and Research

The global response to the COVID-19 pandemic has been structured around the idea that human connection and sociality are bad—they are dangerous. This essay suggests that, perhaps paradoxically, rather than isolating to stay healthy, people are forging new egalitarian forms of connection. I argue that COVID-19 has enhanced experiments in what I will call a “burgeoning feminist commons.” These foreground new, horizontal forms of sociality, and they build the grounds of resistance, refusing to separate the time of political organization from that of reproduction. I discuss three such experiments: masked mobs, friendly fridges, and pandemic pods. Each form of connection …

Reports And Commands: Deciphering A Health Exhibition Using The Speaking Mnemonic, David H. Lee

Publications and Research

The Amazing You exhibition at the Tampa Museum of Science and Industry had over 400 different multimedia health exhibits. Visitors walked through life stages, from conception through death, the exhibits at first showcasing developmental milestones, then diseases and chronic conditions associated with ageing. Museum executives described the exhibition as a public health intervention that stressed disease prevention, screening and behaviour change. This piece considers the question: What makes an exhibition be a health intervention? To describe complexities of the communication environment I use a mnemonic device called SPEAKING, an acronym for ‘Scene/Setting, Participants, Ends, Act Sequence, Key, Instrumentalites, Norms and …

Analog Video In The Age Of Digital Data: A Case Study Of Shigeko Kubota's "Social Practice", Helena Shaskevich, Lia Robinson

Publications and Research

If Nam June Paik truly is the “father of video art,” as so many scholars claim, then Shigeko Kubota is in many ways its mother, performing the unacknowledged and undervalued labor of managing the “house” of video and taking care of its inhabitants. My digital art history project for Panorama, which performs a data-driven deep dive into Kubota’s networks, argues that Kubota’s legacy must be understood as a lived, “social practice” of care for video art and its communities.

Peer Leading Small Group Discussion During Covid-19, A. E. Dreyfuss, Ana Fraiman, Milka O. Montes, Reagan Hudson, Fernando Montalvillo Ortega, Jonathan Muniz, Franziska Piefke, Mikayla Rodriguez, Meinar Sheila, Keyshla Vargas, Nicky Vu

Publications and Research

Peer-led workshops in General Chemistry at the University of Texas Permian Basin (UTPB) were affected by COVID-19 restrictions during the 2020-2021 academic year. Most Peer-Led Team Learning (PLTL) workshops were conducted in person, but with the difference that protocols of distancing had to be observed, and a few were conducted online, so adjustments were necessary to prepare Peer Leaders to conduct their workshops in both types of settings. The facets of the modified PLTL program were supported by the online preparation for facilitation and chemistry content.

The results of an examination of critical incidents are shared here. This qualitative examination …

Conjunctional Concepts: The Conceptual Teaching Technique In Biology Classes, Igor V. Zaitsev

Publications and Research

Conceptual teaching relies on concepts in conjunction with a bigger conceptual category (or categories). Revealing and using conceptual conjunctions in the science classroom means teaching conceptually. To make conceptual teaching more accessible to biology instructors, a three-concept model was described to be used during a lecture. This model has allowed the author to develop a relatively simple method that starts with an active concept or concepts, then introduces conjunctional and supporting concepts to relate the content to other concepts and relevant real-world applications. This method is intended to help instructors in preparing to teach biological concepts conceptually, in order to …

Factors Influencing The Relationship Between Work-Related Stress And Posttraumatic Stress Disorder Among Working Black Adults In The United States, Paul C. Archibald

Publications and Research

Introduction: Work-related stress (WRS) and posttraumatic disorder (PTSD) is higher among Black adults relative to their White counterparts. Trauma exposure is not the only connection to increased risk for PTSD as WRS is highly associated with risk for PTSD. However, the factors that link WRS and PTSD among working Black adults is not well understood. Materials and Methods: Cross-sectional data from the National Survey of American Life was used to examine the relationship between WRS and PTSD among 2,139 working Black adults and to determine whether there are influencing factors. Results: Logistic regression analyses revealed that working …

Effectiveness And Safety Of Apixaban Versus Warfarin Among Older Patients With Venous Thromboembolism With Different Demographics And Socioeconomic Status, Alexander T. Cohen, Janvi Sah, Amol Dhamane, Theodore Lee, Lisa Rosenblatt, Patrick Hlavacek, Birol Emir, Allison V. Keshishian, Huseyin Yuce, Xuemei Luo

Publications and Research

Introduction

Impact of demographics and socioeconomic status (SES) on anticoagulant treatment outcomes among patients with venous thromboembolism (VTE) is not well understood. This study evaluated risks of recurrent VTE, major bleeding (MB), and clinically relevant non-major bleeding (CRNMB) among older patients with VTE initiating apixaban or warfarin stratified by demographics and SES.

Methods

Adult patients (≥ 65 years) who initiated apixaban or warfarin after a VTE event were selected from the US CMS Medicare database (September 2014–December 2017). Stabilized inverse probability treatment weighting (IPTW) was used to balance patient characteristics between treatment cohorts. Patients were stratified by age, gender, race, …

Intergenerational Differences In Dietary Acculturation Among Ghanaian Immigrants Living In New York City: A Qualitative Study, Margrethe F. Horlyck-Romanovsky, Terry T.-K Huang, Ramatu Ahmed, Sandra E. Echeverria, Katarzyna Wyka, May May Leung, Anne E. Sumner, Melissa Fuster

Publications and Research

Dietary acculturation may explain the increasing risk of diet-related diseases among African immigrants in the United States (US). We interviewed twenty-five Ghanaian immigrants (Youth n 13, Age (Mean ± SD) 20 y±5⋅4, Parents (n 6) and Grandparents (n 6) age 58⋅7± 9⋅7) living in New York City (NYC) to (a) understand how cultural practices and the acculturation experience influence dietary patterns of Ghanaian immigrants and (b) identify intergenerational differences in dietary acculturation among Ghanaian youth, parents and grandparents. Dietary acculturation began in Ghana, continued in NYC and was perceived as a positive process. At the interpersonal level, parents encouraged youth …

Hostile, Quick-Tempered, And Exposed To Dangerous Environments: Exploring The Link Between Temperament And Street Code Adherence, Kevin T. Wolff, Sharron Spriggs, Jonathan Intravia, Michael T. Baglivio, Matt Delisi

Publications and Research

Although Elijah Anderson’s (1999) code of the street thesis has received a great deal of scholarly attention, fewer studies have examined the characteristics associated with its adoption. Existing evidence is supportive of Anderson’s initial observations, however, less is known about the association between personality and emotional characteristics and adopting street code norms. The current study assesses the role of Delisi and Vaughn’s difficult temperament index in the adoption of the street code among a sample of juvenile justice-involved youth. Results indicated youth with more difficult temperaments, characterized by lower levels of effortful control and higher levels of negative emotionality, were …

Leveraging High-Resolution 7-Tesla Mri To Derive Quantitative Metrics For The Trigeminal Nerve And Subnuclei Of Limbic Structures In Trigeminal Neuralgia, Judy Alper, Alan C. Seifert, Gaurav Verma, Kuang-Han Huang, Yael Jacob, Ameen Al Qadi, John W. Rutland, Sheetal Patel, Joshua Bederson, Raj K. Shrivastava, Bradley N. Delman, Priti Balchandani

Publications and Research

Background: Trigeminal Neuralgia (TN) is a chronic neurological disease that is strongly associated with neurovascular compression (NVC) of the trigeminal nerve near its root entry zone. The trigeminal nerve at the site of NVC has been extensively studied but limbic structures that are potentially involved in TN have not been adequately characterized. Specifically, the hippocampus is a stress-sensitive region which may be structurally impacted by chronic TN pain. As the center of the emotion-related network, the amygdala is closely related to stress regulation and may be associated with TN pain as well. The thalamus, which is involved in the trigeminal …

Crowd Salience Heightens Tolerance To Healthy Facial Features, Mitch Brown, Ryan E. Tracy, Steven G. Young, Donald F. Sacco

Publications and Research

Objective: Recent findings suggest crowd salience heightens pathogen-avoidant motives, serving to reduce individuals’ infection risk through interpersonal contact. Such experiences may similarly facilitate the identification, and avoidance, of diseased conspecifics. The current experiment sought to replicate and extend previous crowding research.

Methods: In this experiment, we primed participants at two universities with either a crowding or control experience before having them evaluate faces manipulated to appear healthy or diseased by indicating the degree to which they would want to interact with them.

Results: Crowding-primed participants reported a more heightened preferences for healthy faces than control-primed participants. Additionally, crowd salience reduced …

Police Officers’ Best Friend?: An Exploratory Analysis Of The Effect Of Service Dogs On Perceived Organizational Support In Policing, Kenneth M. Quick, Eric L. Piza

Publications and Research

This study explored the effectiveness of a novel technique for police departments to support their officers and promote wellness: the use of service dogs. We evaluated officer perceptions in two mid-sized, municipal police departments that have wellness programs with a service dog that is permanently assigned to a full-time police officer handler: Groton and Naugatuck, Connecticut. We assessed 6 factors believed to influence police officer wellness including: operational and organizational stress using the Police Stress Questionnaire (McCreary & Thompson, 2006); topical stressors including those related to the COVID-19 pandemic, police use of force and community relations, and police reform efforts; …

Fast Estimation Of Matrix Exponential Spatial Models, Ye Yang, Osman Doğan, Süleyman Taşpınar

Publications and Research

The matrix exponential spatial specification (MESS) is an alternative to the spatial autoregressive-type (SAR-type) specifications with several attractive properties. The spatial dependence in the MESS-type models is formulated through a matrix exponential term, and the estimation of these models may require the computation of the matrix exponential terms many times in an estimation procedure. In the literature, it is well documented that the computation of the matrix exponential terms can pose challenges in terms of reliability, stability, accuracy, and efficiency. We propose a matrix-vector products approach based on the truncation of Taylor series expansion of the matrix exponential terms for …

During Natural Viewing, Neural Processing Of Visual Targets Continues Throughout Saccades, Atanas D. Stankov, Jonathan Touryan, Stephen Gordon, Anthony J. Ries, Jason Ki, Lucas C. Parra

Publications and Research

Relatively little is known about visual processing during free-viewing visual search in realistic dynamic environments. Free-viewing is characterized by frequent saccades. During saccades, visual processing is thought to be suppressed, yet we know that the presaccadic visual content can modulate postsaccadic processing. To better understand these processes in a realistic setting, we study here saccades and neural responses elicited by the appearance of visual targets in a realistic virtual environment. While subjects were being driven through a 3D virtual town, they were asked to discriminate between targets that appear on the road. Using a system identification approach, we separated overlapping …

Our Year Of Remote Reference: Covid19’S Impact On Reference Services And Librarians, Sarah B. Cohn, Rebecca Hyams

This article focuses on the impact COVID-19 had on reference services themselves, as well as the perceptions of those who provide them.

Foundations Of Linguistics And Identity In L2 Teaching And Learning: Agency Through Linguistic Enrichment, Differentiated Instruction And Teacher Identity, Marnie Jo Petray, Rebecca Shapiro, Gladys M. Vega

Publications and Research

Language, procedure, and identity are L2 teaching/learning essentials that may promote agency and stimulate synergies among knowledge, practice, and reflection (Diaz Maggioli, 2014; Duff, 2012). This meta-report presents three studies that collectively advance agency and endorse linguistic foundations as enrichment, differentiated instruction as engagement, and teacher identity as empowerment. All of these theoretical constructs are key to successful L2 teaching and acquisition. Study 1 quantitatively reports on introductory linguistics’ presence or absence in 114 master’s programs at 54 US institutions. Findings suggest that linguistics’ curricular presence is inconsistent and training for optimal impact in the L2 classroom is lacking. Given …

Psilocybin Newspaper Coverage – Sentiment And Frequency (1989-2020), Dax Oliver

Publications and Research

A growing body of medical research has focused on the chemical compound psilocybin in recent years. However, this research is not merely a scientific issue but also a social and political one. In the 1960s, psilocybin and other psychedelics were often ingested outside of research settings. This alarmed many people, resulting in severe legal restrictions on psilocybin research. Today, many psilocybin advocates hope that it will avoid the negative public sentiment of the 1960s. To help gauge public sentiment about other psychoactive compounds, some studies have examined newspaper coverage. The present study hoped to build a similar gauge with newspaper …

Health-Related Quality Of Life And Mental Well-Being Of Healthy And Diseased Persons In 8 Countries: Does Stringency Of Government Response Against Early Covid-19 Matter?, Di Long, Juanita A. Haagsma, Mathieu F. Janssen, John N. Yfantopoulos, Erica I. Lubetkin, Gouke J. Bonsel

Publications and Research

Objectives

Our study aimed to (1) assess health-related quality of life (HRQoL) and mental well-being of healthy and diseased persons in the general population during the early stage of the COVID-19 pandemic and (2) examine the relationship between HRQoL and mental well-being and individual characteristics and government response against COVID-19, as measured by the stringency index.

Methods

A web-based survey was administered to a cohort of persons from the general population of eight countries: Greece, Italy, the Netherlands, Russia, South Africa, Sweden, the United Kingdom (UK) and the United States of America (US) from April 22 to May 5 and …

Must Consent Be Informed? Patient Rights, State Authority, And The Moral Basis Of The Physician's Duties Of Disclosure, D. Robert Macdougall

Publications and Research

Legal standards of disclosure in a variety of jurisdictions require physicians to inform patients about the likely consequences of treatment, as a condition for obtaining the patient’s consent. Such a duty to inform is special insofar as extensive disclosure of risks and potential benefits is not usually a condition for obtaining consent in non-medical transactions.

What could morally justify the physician’s special legal duty to inform? I argue that existing justifications have tried but failed to ground such special duties directly in basic and general rights, such as autonomy rights. As an alternative to such direct justifications, I develop an …

No Ordinary Proteins: Adsorption And Molecular Orientation Of Monoclonal Antibodies, Ankit D. Kanthe, Andrew Ilott, Mary Krause, Songyan Zheng, Jinjiang Li, Wei Bu, Mrinal K. Bera, Binhua Lin, Charles Maldarelli, Raymond S. Tu

Publications and Research

The interaction of monoclonal antibodies (mAbs) with air/water interfaces plays a crucial role in their overall stability in solution. We aim to understand this behavior using pendant bubble measurements to track the dynamic tension reduction and x-ray reflectivity to obtain the electron density profiles (EDPs) at the surface. Native immunoglobulin G mAb is a rigid molecule with a flat, “Y” shape, and simulated EDPs are obtained by rotating a homology construct at the surface. Comparing simulations with experimental EDPs, we obtain surface orientation probability maps showing mAbs transition from flat-on Y-shape configurations to side-on or end-on configurations with increasing concentration. …

Covid‑19, Race/Ethnicity, And Age: The Role Of Telemedicine To Close The Gaps On Health Disparities, Andreas Kakolyris, Juan J. Delacruz, Christos I. Giannikos

Publications and Research

The novel COVID-19 outbreak is a major public health challenge that quickly turned into an economic recession of great proportions. This pandemic poses a trade-off between health and the economy where social distancing, quarantines, and isolation shut down demand and supply chains across the USA. This paper analyzes the impact of COVID-19 on illness and death among older adults and communities of color with low socioeconomic status in New York City. To achieve this goal, fractional logit models are used to capture changes in the novel virus’ morbidity and mortality rates at the neighborhood level. Median income, race/ethnicity, age, household …

Safety And Belonging In Immigrant-Serving Districts: Domains Of Educator Practice In A Charged Political Landscape, Rebecca Lowenhaupt, Dafney Blanca Dabach, Ariana Mangual Figueroa

Publications and Research

Drawing from a context of reception framework, this article asks the following questions: How do educators describe issues of safety and belonging in the context of a charged immigration policy climate? What practices have educators developed to support immigrant-origin youth? And, what are the relationships between educators’ perceptions of safety and belonging and educator practices? We analyze educators’ survey responses administered across six school districts in different contexts across the United States, including the Northeast, Midwest, South, and West. We synthesize four domains of educator practice: signaling affirmation, building shared knowledge and capacity, finding and mobilizing resources, and creating space …

Modeling Covid-19 Spread In Small Colleges, Riti Bahl, Nicole Eikmeier, Alexandra Fraser, Matthew Junge, Felicia Keesing, Kukai Nakahata, Lily Reeves

Publications and Research

We develop an agent-based model on a network meant to capture features unique to COVID-19 spread through a small residential college. We find that a safe reopening requires strong policy from administrators combined with cautious behavior from students. Strong policy includes weekly screening tests with quick turnaround and halving the campus population. Cautious behavior from students means wearing facemasks, socializing less, and showing up for COVID-19 testing. We also find that comprehensive testing and facemasks are the most effective single interventions, building closures can lead to infection spikes in other areas depending on student behavior, and faster return of test …
