Cap-Assisted Endoscopic Treatment Of Esophageal Food Bolus Impaction And/Or Foreign Body Ingestion: A Systematic Review And Meta-Analysis, Babu P. Mohan, Jay Bapaye, Syed Hamaad Rahman, Priyadarshini Loganathan, Arunkumar Muthusamy, Daryl Ramai, Suresh Ponnada, Saurabh Chandan, John Fang

Student Publications

Background: Esophageal food bolus and/or foreign body (FB) impaction is a common gastrointestinal emergency. This meta-analysis reports on the pooled outcomes of cap-assisted endoscopic removal of esophageal FB.

Methods: We conducted a comprehensive search of several databases (inception to February 2022) to identify studies reporting on the use of a cap in the endoscopic treatment of esophageal FB ingestion. A random effects model was used to calculate the pooled odds ratio (OR) and mean difference (MD), and I2 values were used to assess the heterogeneity.

Results: Six studies were analyzed that included 677 patients treated with cap-assisted and 694 with …

Period, Break, Form, David Sergeant

School of Law, Humanities and Social Sciences

This essay examines the relationship between novelistic form and a historical moment shaped by new technologies in Dave Eggers's The Circle (2013) and Kim Stanley Robinson's Red Moon (2018). In both, the novel form is itself positioned as a major counterforce against the malignant powers that are attempting to form the age. Also in both, new technologies are understood not as primary or independent shaping forces but as enabling components of a larger political and economic form, a variant of capitalism. However, the crucial difference between the two novels is in how they periodize this capitalism, an act that is …

Microfibers: Environmental Problems And Textile Solutions, Js Weis, Francesca De Falco

School of Geography, Earth and Environmental Sciences

Microplastics have become a topic of considerable concern and intensive study over the past decade. They have been found everywhere in the oceans, including the deepest trenches and remotest parts of the Arctic. They are ingested by many animals and some are incorporated into tissues. There is considerable effort in studying what effects they have on marine life. It has become clear that when water samples are collected in ways that prevent most long thin particles from escaping through pores of a net, the most abundant type of microplastics found in water and sediments are microfibers (fibers with dimensions less …

A Butterfly In Covid: Structural Racism And Baltimore's Pretrial Legal System, Doug Colbert, Colin Starger

All Faculty Scholarship

Summer of 2020 represented a potentially pivotal moment in the movements against mass incarceration and for racial justice. The authors commenced a study of Baltimore’s pretrial legal system just as the convergence of the COVID-19 pandemic and urgent cries of Black Lives Matter appeared to present a once-in-a-generation opportunity for meaningful decarceration. Over forty-four weekdays in June and July, the team observed bail review hearings in 509 cases and collected extensive data from the arguments and recommendations offered by the pretrial agency and prosecuting and defense attorneys. Unfortunately, the hoped-for reform failed to materialize as judges held nearly 62% of …

Is There A Strategic Organization In The Behavioral Theory Of The Firm? Looking Back And Looking Forward, Henrich R. Greve, Cyndi Man Zhang

Research Collection Lee Kong Chian School Of Business

In the 20 years of Strategic Organization, how well has knowledge drawn from the behavioral theory of the firm contributed to the field of strategy? We see progress both in the pages of SO! and elsewhere in the field of strategy, but this progress has been held back by divisions between strategy and organization theory in what theories should predict, what mechanisms are preferable predictors, and what outcomes are of interest. Despite these divisions, the last few years have seen particularly rapid progress, turning the behavioral theory of the firm into one of multiple organization theory sources of strategy knowledge. …

OBJECTIVE: This study examined the association of weight loss following bariatric surgery with self-reported sleep quality after accounting for other sleep-related factors.

METHODS: Participants were from the Bariatric Experience Long Term (BELONG) study. Participants completed a survey up to 6 months before surgery and approximately 1 year after surgery. The Pittsburgh Sleep Quality Index (PSQI) was used to measure sleep quality. One-year percentage total weight loss (%TWL) was determined from electronic medical records. Covariates included demographics, Charlson Comorbidity Index, geocoded variables to assess neighborhood quality, and physical activity. The authors assessed the association between %TWL at 1 year and PSQI …

Seeing The World Through Their Eyes: The Impact Of Place Attachment On Teachers' Understanding Of Worldviews, Kathleen Murray

Theses & Dissertations

Over the past 20 years, Long Island, New York, has seen an increase in linguistic and racial diversity within its schools. The growth in linguistic diversity has brought with it an increase in English language learners (ELLs), representing almost a 50% increase since 2012. As the ELL population has grown, so has the achievement gap between ELLs and their non-ELL peers. The current teaching staff on Long Island does not match the diversity of its student population. Prior research has shown that the cultural mismatch between the teachers and students is one contributing factor to the aforementioned achievement gap. In …

Infrastructure's (Supra)Sacralizing Effects: Contesting Littoral Spaces Of Fishing, Faith, And Futurity Along Sri Lanka's Western Coastline, Orlando Woods

Research Collection School of Social Sciences

This paper explores the ways in which infrastructural development can cause the sacred to become a source of political legitimacy, and sacred authority to become a politically charged construct. For resource-dependent communities, the ecological damage caused by infrastructural development can cause ostensibly profane issues to be imbued with sacred meaning and value. With sacralization comes the expectation that figures of sacred authority will campaign for justice on behalf of the communities that they represent. However, when the authority evoked comes from outside the boundaries of institutionalized religion, processes of suprasacralization come into play. By exploring infrastructure’s (supra)sacralizing effects, I demonstrate …

Deliberate Errors Promote Meaningful Learning, Sarah Shi Hui Wong, Stephen Wee Hun Lim

Research Collection School of Social Sciences

Our civilization recognizes that errors can be valuable learning opportunities, but for decades, they have widely been avoided or, at best, allowed to occur as serendipitous accidents. The present research tested whether greater learning success could paradoxically be achieved through making errors by intentional design, relative to traditional errorless learning methods. We show that deliberately committing and correcting errors even when one knows the correct answers enhances learning—a counterintuitive phenomenon that we termed the derring effect. Across two experiments (N = 160), learners engaged in open-book study of scientific expository texts and were then tested on their retention and higher-order …

Travel Behavior Change And Economic Transition In Gentrified Neighborhoods, Maryam Izadi

LSU New Orleans Theses and Dissertations

Post-industrial cities in the US have experienced social and economic transitions, mostly in declining downtown neighborhoods. This process, known as gentrification, typically involves revitalization that reverses the decline and disinvestment in inner-city neighborhoods. The industrial shift increased the demand for housing near downtown. The employment of college-educated and high-skill workers has been centralized, while low-skilled jobs continue to decline downtown. While the impacts of gentrification on housing and residential displacement is frequently investigated, little attention has been given to its impact on travel behavior change and economic transition, which is the focus of this research. Change in travel behavior is …

Warts, hypogammaglobulinemia, infections, and myelokathexis (WHIM) syndrome (WS) is a combined immunodeficiency caused by gain-of-function mutations in the C-X-C chemokine receptor type 4 (CXCR4) gene. We characterize a unique international cohort of 66 patients, including 57 (86%) cases previously unreported, with variable clinical phenotypes. Of 17 distinct CXCR4 genetic variants within our cohort, 11 were novel pathogenic variants affecting 15 individuals (23%). All variants affect the same CXCR4 region and impair CXCR4 internalization resulting in hyperactive signaling. The median age of diagnosis in our cohort (5.5 years) indicates WHIM syndrome can commonly present in childhood, although some patients are not …

[Preface To] Peace, Preference, And Property: Return Migration After Violent Conflict, Sandra F. Joireman

Bookshelf

Growing numbers of people are displaced by war and violent conflict. In Ukraine, Afghanistan, Ethiopia, Myanmar, Syria, and elsewhere violence pushes civilian populations from their homes and sometimes from their countries, making them refugees. In previous decades, millions of refugees and displaced people returned to their place of origin after conflict or were resettled in countries in the Global North. Now displacements last longer, the number of people returning home is lower, and opportunities for resettlement are shrinking. More and more people spend decades in refugee camps or displaced within their own countries, raising their children away from their home …

Mobility Interrupted: A New Framework For Understanding Anti-Left Sentiment Among Brazil’S “Once-Rising Poor”, Benjamin Junge, Sean T. Mitchell, Charles H. Klein, Matthew Spearly

Anthropology Faculty Publications and Presentations

How do sequences of upward and downward socioeconomic mobility influence political views among those who have “risen” or “fallen” during periods of leftist governance? While existing studies identify a range of factors, long-term mobility trajectories have been largely unexplored. The question has particular salience in contemporary Brazil, where, after a decade of extraordinary poverty reduction on the watch of the leftist Workers’ Party (PT), a subsequent period of economic and political crises intensified anti-PT sentiment. This article uses original data from the 2016 Brazil’s Once-Rising Poor (BORP) Survey, using a 3-city sample of 822 poor and working-class Brazilians to analyze …

National Forest Visitation Preferences And Avenues To Participation For Urban Hispanic Recreationists In The Portland Metropolitan Area (Usa), Lee Cerveny, Rebecca Mclain, David Banis, Matthew Helmer

Geography Faculty Publications and Presentations

Health benefits of outdoor recreation have been broadly demonstrated and land managers recognize the equity implications of providing safe and inclusive outdoor spaces. Data on public lands visitation and outdoor participation show that Hispanic recreationists are less likely to engage in outdoor leisure than White persons. Early studies of outdoor preferences of Hispanic persons identified a desire for large-group settings and social activities. To update our understanding of outdoor recreation needs, preferences, and constraints, we collaborated with a Latinx organization in Portland, Oregon (USA). We collaboratively designed three focus groups that combined structured engagement, cognitive sorting, and participatory mapping to …

Pedestrian Wayfinding Under Consideration Of Visual Impairment, Blindness, And Deafblindness: A Mixed-Method Investigation Into Individual Experiences And Supporting Elements, Martin Swobodzinski, Amy T. Parker, Elizabeth Schaller, Denise Snow

TREC Final Reports

In this report we discuss to-date findings of a project that aimed at assessing individual and environmental affordances in the context of human pedestrian wayfinding of visually impaired, blind, and deafblind travelers in public spaces. Our project afforded collaboration, co-design, and co-creation of knowledge between the investigators, partners at the American Printing House of the Blind and GoodMaps, the Portland State University Digital City Testbed Center, and members of the disability community. The objective of the project was to better understand how different wayfinding aids, that is, wayfinding apps, tactile maps, and verbal route descriptions, are employed by visually impaired, …

Setting Up Shop Down South: Gay Visibility And Identity Formation At A New Orleans Bookstore, Katelyn N. Spencer

LSU Master's Theses

Looking specifically at the South’s first gay bookstore, Faubourg Marigny (FM) Books, this thesis will connect the existence of gay literature and space as impetuses of gay community identity within New Orleans. It will use the political, social, and cultural histories of the 1970s through the 2010s to contextualize the gay bookstore as a microcosm of its time and location. In doing so, it will examine how FM Books’ New Orleans location affected its function and its relationship with its community. It will also analyze how the bookstore fit into the city’s history of social tradition and aversion to flagrant …

A Comparison Of Us Medicare Expenditures For Hemodialysis And Peritoneal Dialysis, Jennifer M Kaplan, Jingbo Niu, Vivian Ho, Wolfgang C Winkelmayer, Kevin F Erickson

Center for Medical Ethics and Health Policy Staff Publications

Background: Observations that peritoneal dialysis (PD) may be an effective, lower-cost alternative to hemodialysis for the treatment of ESKD have led to policies encouraging PD and subsequent increases in its use in the United States.

Methods: In a retrospective cohort analysis of Medicare beneficiaries who started dialysis between 2008 and 2015, we ascertained average annual expenditures (for up to 3 years after initiation of dialysis) for patients ≥67 years receiving in-center hemodialysis or PD. We also determined whether differences in Medicare expenditures across dialysis modalities persisted as more patients were placed on PD. We used propensity scores to match 8305 …

Sunshine Laws Behind The Clouds: Limited Transparency In A Time Of National Emergency, Ira P. Robbins

Scholarly Articles in Law Reviews & Journals

The COVID-19 pandemic dramatically changed the way citizens lived their lives, businesses operated, and governments functioned. With most people forced to stay home, the pandemic also disrupted how people received their news and other essential information. Public records and public meetings had to adapt to face the growing challenges in a locked-down world. While some governmental bodies were able to keep up with the threat that COVID-19 posed against transparency, others either failed to acclimate to the new normal or actively took advantage of the circumstances to limit how much the public knew not only about the crisis, but about …

Fragmented Or Aligned Climate Action: Assessing Linkages Between Regional And Local Planning Efforts To Meet Transportation Greenhouse Gas Emissions Reduction Targets, Serena E. Alexander, Ahoura Zandiatashbar, Branka Tatarevic

Mineta Transportation Institute

Amid the rising climate change concerns, California enacted Senate Bill 375 (SB 375) to tackle transportation greenhouse gas (GHG) emissions. SB 375 requires Metropolitan Planning Organizations (MPOs) to develop a Sustainable Communities Strategy (SCS), a regional transportation and land use vision plan, to reduce GHG emissions. Meanwhile, a local government can develop a Climate Action Plan (CAP), a non-binding, voluntary plan to reduce GHG emissions that may align with the regional SCS. Recent progress reports indicate California is not making sufficient progress to meet SB 375 emissions reduction targets, which raises important questions: (1) Are the transportation and land use …

BACKGROUND: Multisystem inflammatory syndrome in children (MIS-C) is a postinfectious severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-related complication that has disproportionately affected racial/ethnic minority children. We conducted a pilot study to investigate risk factors for MIS-C aiming to understand MIS-C disparities.

METHODS: This case-control study included MIS-C cases and SARS-CoV-2-positive outpatient controls less than 18 years old frequency-matched 4:1 to cases by age group and site. Patients hospitalized with MIS-C were admitted between March 16 and October 2, 2020, across 17 pediatric hospitals. We evaluated race, ethnicity, social vulnerability index (SVI), insurance status, weight-for-age and underlying medical conditions as risk …

Automatic Concrete Sidewalk Deficiency Detection And Mapping With Deep Learning, Yuhan Jiang, Sisi Han, Dapeng Li, Yong Bai, Mingzhu Wang

Civil and Environmental Engineering Faculty Research and Publications

Vertical displacement is a common concrete slab sidewalk deficiency, which may cause trip hazards and reduce wheelchair accessibility. This paper presents an automatic approach for trip hazard detection and mapping based on deep learning. A low-cost mobile LiDAR scanner was used to obtain full-width as-is conditions of sidewalks, after which a method was developed to convert the scanned 3D point clouds into 2D RGB orthoimages and elevation images. Then, a deep learning-based model was developed for pixelwise segmentation of concrete slab joints. Algorithms were developed to extract different types of joints of straight and curved sidewalks from the segmented images. …

The Romantic Author As Compelled Speaker, Sonya G. Bonneau

Georgetown Law Faculty Publications and Other Works

The romantic author trope has been extensively criticized in the copyright context, yet it threatens to emerge as a new pillar of First Amendment compelled speech jurisprudence. Justice Thomas’s concurring opinion in Masterpiece Cakeshop v. Colorado Civil Rights Commission exemplifies the trope’s rhetorical power, and the costs of that approach. Casting the baker as an artist, Justice Thomas finds that creating custom wedding cakes was speech, and that applying a public accommodations law to require service to a same-sex couple triggered strict scrutiny review. This is an extraordinary result. Although the Court never adjudicated the compelled speech claim, it will …

Participatory Mapping To Address Neighborhood Level Data Deficiencies For Food Security Assessment In Southeastern Virginia, Usa, Nicole S. Hutton, George Mcleod, Thomas R. Allen, Christopher Davis, Alexander Garnand, Heather Richter, Prachi P. Chaven, Leslie Hoglund, Jill Comess, Matthew Herman, Brian Martin, Cynthia Romero

Political Science & Geography Faculty Publications

Background: Food is not equitably available. Deficiencies and generalizations limit national datasets, food security assessments, and interventions. Additional neighborhood level studies are needed to develop a scalable and transferable process to complement national and internationally comparative data sets with timely, granular, nuanced data. Participatory geographic information systems (PGIS) offer a means to address these issues by digitizing local knowledge.

Methods: The objectives of this study were two-fold: (i) identify granular locations missing from food source and risk datasets and (ii) examine the relation between the spatial, socio-economic, and agency contributors to food security. Twenty-nine subject matter experts from three cities …

Leveraging Text Mining For Trend Analysis And Comparison Of Sustainability Reports: Evidence From Fortune 500 Companies, Anuj Sharma, Kapil Kaushik, Prakash Awasthy, Abhishek Gawande

American Business Review

In the recent upsurge in environmental concerns, business sustainability has become more prominent than ever. Organizations worldwide are expected to function sustainably, causing the least negative impact on the environment and promoting harmony among the firm, environment, and society. Most firms report their actions related to sustainability in corporate social responsibility (CSR) reports. This research aims to understand and analyze contemporary trends in CSR reports by Fortune 500 companies using text mining. It compares how the focus of sustainability reports varies across countries and industries along key dimensions of sustainability (i.e., environmental, economic, social, and government). Findings from the study …

Migration, The Quality Of Life, And Economic Opportunities In The U.S. Revisited: Impacts Of Round-Trip Work Commute Time And Rent Or Single-Family Housing Prices, Richard J. Cebula

American Business Review

Given the importance to businesses of having a better understanding of factors that influence migration, this study argues that there are two dimensions of the quality of life and economic opportunities that have largely been ignored in previously published studies of migration patterns in the U.S.: the impacts of (1) the costs of commuting between one’s residence and one’s place of employment and (2) apartment rent-levels and single-family housing price levels. It is hypothesized here that the greater the commute time between one’s prospective place of residence and one’s prospective place of employment, the greater the costs associated with in-migration …

Out Of Phase Quaternary Uplift-Rate Changes Reveal Normal Fault Interaction, Implied By Deformed Marine Palaeoshorelines, M. Meschis, G. P. Roberts, J. Robertson, Z. K. Mildon, D. Sahy, R. Goswami, C. Sgambato, J. Faure Walker, A. M. Michetti, F. Iezzi

School of Geography, Earth and Environmental Sciences

We have mapped and constrained the timing of tectonically deformed uplifted Late Quaternary palaeoshorelines in the Messina Strait, southern Italy, an area above a subduction zone containing active normal faults. The palaeoshorelines are preserved from up to thirteen Late Quaternary sea-level highstands, providing a record of the deformation over this timescale (~500 ka) for the Messina-Taormina Fault, the Reggio Calabria Fault and the Armo Fault. The palaeoshorelines reveal spatial patterns of uplift through time along the strike of these normal faults, and, given the across strike arrangement of the faults, also reveal how the contribution of each fault to the …

The impacts of climate change are being felt in Louisiana, in the form of changing weather patterns that have resulted in changes in floods, hurricanes, tornadoes frequencies of occurrence, and magnitudes, among others resulting in, flooding. The variabilities in rainfall in a drainage basin affect water availability and sustainability. This study analyzed the precipitation data of Southeastern Louisiana, United States, for the period 1990 to 2020. Data used in the study was from, Donaldsonville, Galliano, Lafourche, Gonzales, Ascension, Morgan, New Orleans, Audubon, Plaquemine, and Ponchatoula, Tangipahoa, weather stations. These stations were selected because the differences between each of their highest …
