Faculty, Staff and Students Publications

There is limited data on the anticipated perinatal course among gravidae in their sixth and seventh decades. Our objective was to describe the relatively uncomplicated prenatal, intrapartum, and postpartum course of a 67-year-old essential primigravida. Briefly, our patient conceived a singleton pregnancy via IVF with donor oocytes, then presented at 13 6/7 weeks of gestation to initiate prenatal care. Her medical history was significant for chronic hypertension, hyperlipidemia, and obesity. Her cardiac function was monitored throughout pregnancy, and she delivered at 36 1/7 weeks by cesarean for a decline in left ventricular function with mitral regurgitation. Her intrapartum and postpartum …

Perioperative Acute Kidney Injury, Sam D Gumbert, Felix Kork, Maisie L Jackson, Naveen Vanga, Semhar J Ghebremichael, Christy Y Wang, Holger K Eltzschig

Faculty, Staff and Students Publications

Perioperative organ injury is among the leading causes of morbidity and mortality of surgical patients. Among different types of perioperative organ injury, acute kidney injury occurs particularly frequently and has an exceptionally detrimental effect on surgical outcomes. Currently, acute kidney injury is most commonly diagnosed by assessing increases in serum creatinine concentration or decreased urine output. Recently, novel biomarkers have become a focus of translational research for improving timely detection and prognosis for acute kidney injury. However, specificity and timing of biomarker release continue to present challenges to their integration into existing diagnostic regimens. Despite many clinical trials using various …

Faculty, Staff and Students Publications

Spinal cord compression (SCC) is a rare initial presentation and complication of acute lymphoblastic leukemia (ALL) with nearly all reported cases occurring in the pediatric population. We report a 38-year-old previously healthy man who presented with acute on chronic lower back pain, gait instability, urinary retention, and severe thrombocytopenia. Radiologic examination revealed two soft tissue masses of the thoracic spine associated with compression fractures causing spinal canal narrowing and cord compression. Bone marrow biopsy confirmed the diagnosis of ALL. Immediate initiation of high-dose corticosteroids and systemic chemotherapy resolved the patient's symptoms without radiation therapy or surgical intervention. After two courses …

Metaproteomic Analysis Of Human Gut Microbiome In Digestive And Metabolic Diseases, Sheng Pan, Ru Chen

Faculty, Staff and Students Publications

Metaproteomics, as a subfield of proteomics, has quickly emerged as a pivotal tool for global characterization of a microbiome system at a functional level. It has been increasingly applied in studying human digestive and metabolic diseases, and provides information-rich data to identify the dysbiosis of human gut microbiome related to healthy or disease states to elucidate the molecular events underlying host-microbiota interplays. While significant technical challenges still exist, this emerging technology has been demonstrated to provide essential information in interrogating functional changes in the human gut microbiome, complementary to metagenomics and metatranscriptomics. This chapter overviews the overall metaproteomic work flow …

Faculty, Staff and Students Publications

Over the past 20 years, there has been an increased focus on quality improvement (QI) in health care, which is critical in achieving care that is patient-centered, safer, timelier, and more effective, efficient, and equitable. At the center of this movement is QI education, which is known to lead to learning, behavior change, and improved outcomes. However, there is a need for the development and provision of long-duration, interactive, interprofessional training in QI, to allow for in-depth learning and application of learned skills. To this end, we designed a curriculum for an established interprofessional, interactive, web-based QI fellowship for doctorally …

Direct Numerical Simulations Of Acoustic Disturbances In Various Rectangular Nozzle Configurations, Nathaniel Hildebrand, Meelan M. Choudhari, Lian Duan

Mechanical and Aerospace Engineering Faculty Research & Creative Works

We perform Direct Numerical Simulations (DNS) to study the acoustic freestream disturbances radiating from the turbulent boundary layers along the contoured nozzle walls of a hypersonic wind tunnel with a rectangular test section. To begin with, the effects of the spanwise end walls are suppressed by confining the spanwise computational domain to a finite segment of the overall nozzle cross section and by imposing periodic boundary conditions across that spanwise domain. Besides providing a building-block configuration to reveal partial effects of the enclosed acoustic environment within the wind tunnel, these computations serve as a steppingstone toward the goal of fully-3D …

Improving Patient Satisfaction With The Virtual Handoff Process Through The Utilization Of Educational Pamphlets In The Emergency Department, Lynda Michelle Heintz

Doctoral Dissertations and Projects

Boarding patients in the emergency room while waiting to transfer the patient to the proper unit can be harmful to clinical care and have significant financial opportunity costs. At one local hospital it was found that on average patients were being boarded in the emergency room (ED) for approximately 85 minutes waiting to be transferred. Several barriers that caused this delay were found including, delay in room cleaning, nurse staff shortage, and inability to give report to the nurse receiving the patient. In an attempt to combat this delay which may be caused by a difficulty in giving patient report, …

The Knowledge Of End-Time Prophetic Scriptures Prepares Believers At Northcliffe Baptist Church To Expect Religious Persecution, John C. Reddy

Doctoral Dissertations and Projects

The lack of knowledge about the end-time prophetic Scriptures and its inferences to Islamic eschatology appears to be a problem at Northcliffe Baptist Church. The purpose of this study is to raise awareness about the end-time Scriptures and prepare the congregants to expect persecution as normative in the Christian life. Islam is projected to overtake Christianity in a few decades and is proliferating at a rapid pace. The anti-parallel structure between Christian eschatology and Islamic eschatology is disconcerting. Islam denies Jesus’s divinity and advocates persecuting Christians if they do not convert to Islam. Suffering and persecution for the Lord are …

American God Story: Creating Shared Cultural Context With Popular Television, Timothy Joseph Rosenberger

Doctoral Dissertations and Projects

Believers increasingly encounter a stark divide between their cultural contexts and those of the people they seek to evangelize. This divide is particularly pronounced in popular culture where the television, movies, music, and books that appeal to Christians often are radically different than those that appeal to mainstream Americans. Without a shared cultural language, and a shared network of cultural touch points, it can be challenging to form meaningful connection between, and amongst, church members and unchurched community members. This study pioneers an intervention in which church members, and unchurched community members, come together to view popular television episodes and …

Information-Based Particle Flow For High Uncertainty Estimation, Kari C. Ward, Kyle J. Demars

Mechanical and Aerospace Engineering Faculty Research & Creative Works

This work presents a new formulation of the Gaussian particle flow filter derived using an information theoretic approach. The developed information flow addresses two problems with Gaussian particle flow: the lack of inherent meaning in the flow parameters and the inability to easily include modifications for a non-Bayesian update. Equivalency between Gaussian particle flow and information flow is established using a linear, Gaussian example. An orbit determination simulation with high initial uncertainty is used to demonstrate the consistent, robust performance of the information flow filter in situations where the extended Kalman filter fails.

Discounting Credibility: Doubting The Stories Of Women Survivors Of Sexual Harassment, Deborah Epstein

Georgetown Law Faculty Publications and Other Works

For decades, federal and state laws have prohibited sexual harassment on the job; despite this fact, extraordinarily high rates of gender-based workplace harassment still permeate virtually every sector of the American workforce. Public awareness of the seriousness and scope of the problem increased astronomically in the wake of the #MeToo movement, as women began to publicly share countless stories of harassment and abuse. In 2015, the Equal Employment Opportunity Commission’s Task Force on the Study of Harassment in the Workplace published an important study analyzing a wide range of factors contributing to this phenomenon. But the study devotes only limited …

Rationing Safe And Effective Covid-19 Vaccines: Allocating To States Proportionate To Population May Undermine Commitments To Mitigating Health Disparities, Harald Schmidt, Parag A. Pathak, Michelle A. Williams, Tayfun Sönmez, M. Utku Ünver, Lawrence O. Gostin

Georgetown Law Faculty Publications and Other Works

A central goal in the National Academies of Science, Engineering and Medicine’s (NASEM) framework for equitable COVID-19 vaccine allocation is to mitigate existing inequities, particularly those affecting economically worse-off racial and ethnic minorities. The Advisory Committee on Immunization Practice (ACIP) likewise notes that equity demands to “reduce, rather than increase, health disparities in each phase of vaccine distribution”. A crucial question in this regard is how vaccines should be distributed to states. The default is to allocate proportionate to population size. However, this approach risks increasing scarcity for worse-off populations in states where they represent above-average shares. To avoid lower …

The Role Of State And Federal Law In Energy Condemnations, Stewart E. Sterk

Articles

When an energy provider condemns fee interests or easements to permit construction of transmission lines, what roles do state and federal law play in determining the "just compensation" available to affected landowners? That question has arisen in a number of different factual contexts. Usually, condemnors seek to avoid state law rules that provide for compensation beyond what they believe represents the market value of the property they seek to acquire. For instance, condemnors may seek an offset for benefits the condemnation generates for neighboring land owned by the condemnee. Condemnors may also seek to avoid state rules that entitle condemnees …

Machine Learning Techniques For Quantification Of Knee Segmentation From Mri, Sujeet More, Jimmy Singla, Ahed Abugabah, Ahmad Ali Alzubi

What’S Love Got To Do With Educational Leadership? A Case Study In Principal Practice, Dessynie Edwards, Israel Aguilar, Juan Manuel Nino

Organization and School Leadership Faculty Publications

The pressure to close the student achievement gap compounded by federal mandates and laws forces principals to hyper-focus on accountability as one of the major technical aspects of the profession; however, principals who can balance the technical (systems world) with the relational (lifeworld) and facilitate authentic care over aesthetic care, are warranted so that the achievement gap can be understood for what it really is, an opportunity gap. Thus, it’s important to document the processes, strategies, dispositions, or beliefs of school leaders who employ authentic care so that principal preparation programs can teach these as skill sets for preservice leaders …

Becoming Transfronterizo Collaborators: A Transdisciplinary Framework For Developing Translingual Pedagogies In Wac/Wid, Marcela Hebbard, Yanina Hernández

Writing and Language Studies Faculty Publications

Given that pedagogical approaches that challenge dominant language ideologies are not yet well represented in WAC/WID scholarship, this chapter outlines a transdisciplinary framework for developing translingual pedagogies. The framework is built around the notion of transfronterizo/ a collaborators because before instructors can engage their students in exploring and challenging their views toward language, instructors must first critically interrogate their own. This interrogation must consider the unique political, social, economic, and linguistic exigencies of where an institution is located. The chapter concludes by showing that a transdisciplinary and translingual collaboration that is mutually transformative changes faculty collaborators in how they perceive …

Breaking Black Boundaries: The Poetry Of Rita Dove, Lavonna D. Wright

Honors College Theses

By tracing the motifs of domestic space, classical and popular music, and ballroom dancing within Rita Dove’s Thomas and Beulah, Grace Notes, Sonata Mulattica, and American Smooth, I assert that she both challenges and expands Black poetic culture by exploring topics previously considered outside of the purview of Black poets. This analysis allows me to demonstrate her ability as a poet to move beyond simplistic, derivative, and ultimately constraining cultural expectations. Dove uses these motifs to expand the critically and culturally-imposed constrictions of Black poetry.

Benefits Of Using Lesson Study For Sotl, Cross-Disciplinary Research, And Assessment, M. Lauren Wahman, Amber Burkett Peplow, Rita Kumar, Brenda Refaei

International Journal for the Scholarship of Teaching & Learning

Lesson study is a technique that helps faculty examine student learning that encourages scholarly teaching. In lesson study, faculty identify a concept and develop a lesson plan to support student learning of the concept. The opportunity to collaborate on lesson development and to examine student learning opens up a space for faculty to exchange ideas about effective teaching. Most faculty do not have opportunities to collaborate on their teaching at this deeper level, but a lesson study project provides guidance for instructors to explore student learning in-depth. This article examines how lesson study provides opportunities for college faculty to engage …

Students’ Conceptions Of Bell Curve Grading Fairness In Relation To Goal Orientation And Motivation, Lynette Tan Yuen Ling, Brenda Yuen, Wee Ling Loo, Christiaan Prinsloo, Mark Gan

International Journal for the Scholarship of Teaching & Learning

The controversial bell curve has received considerable attention in recent years as a grade distribution tool where “norm-referenced grading involves comparing students’ performances with each other” rather than where they fall on a “predefined continuum of quality” (Brookhart, 2013, p. 258). Despite educators’ deep concern on the fairness of bell curve grading, there is little research done on students’ conceptions of that grading system in higher education. This correlational study uses open-ended questions and three instruments to measure students’ conceptions of the fairness of bell curve grading, their goal orientations, and motivation. Undergraduates from three universities participated in the survey …

Perspective As A Threshold Concept In Business Communication, Kristen M. Getchell, Paula J. Lentz

Using an SoTL framework, the researchers explore the effect of teaching threshold concepts in a summary writing assignment in a foundational business communication class. Working with a close reading methodology, the authors examine the context of perspective as a threshold concept by analyzing students’ summary samples for gender bias and explore how close reading can support further research into threshold concepts in business communication.

Syllabus Language, Teaching Style, And Instructor Self-Perception: Toward Congruence, Christopher Richmann, Courtney Kurinec, Matthew Millsap

International Journal for the Scholarship of Teaching & Learning

As with all language, the words of a syllabus carry emotional associations. Previous literature has not objective-ly measured the emotional associations of syllabus language or explored the relationship between instructors’ teaching style and the emotional associations of syllabus language. Using the Pleasure-Arousal-Dominance (PAD) framework, this article reports baseline measurements for syllabus language, investigates the relationship be-tween Grasha’s teaching styles and instructors’ self-perceived emotional associations with teaching, and compares instructors’ self-perceptions with the emotional associations of their syllabus language. Moderate correlations between teaching PAD scores and Grasha’s teaching style inventory suggest the emotion that may connect with concrete teaching attitudes and …
