“Born For A Storm”: Hard-Right Social Media And Civil Unrest, Daniel Karell, Andrew Linke, Edward Holland, Edward Hendrickson

Geosciences Faculty Publications and Presentations

Does activity on hard-right social media lead to hard-right civil unrest? If so, why? We created a spatial panel dataset comprising hard-right social media use and incidents of unrest across the United States from January 2020 through January 2021. Using spatial regression analyses with core-based statistical area (CBSA) and month fixed effects, we find that greater CBSA-level hard-right social media activity in a given month is associated with an increase in subsequent unrest. The results of robustness checks, placebo tests, alternative analytical approaches, and sensitivity analyses support this finding. To examine why hard-right social media activity predicts unrest, we draw …

Gentrification And Air Quality In A Large Urban County In The United States, Hollis Hutchings, Qiong Zhang, Sue Grady, Lainie Mabe, Ikenna C. Okereke

Public Health Sciences Articles

Introduction: Increases in industrialization and manufacturing have led to worsening pollution in some components of air quality. In addition, gentrification is occurring in large cities throughout the world. As these socioeconomic and demographic changes occur, there have been no studies examining the association of gentrification with air quality. To investigate this association, we studied the trends of gentrification, changes in racial distribution and changes in air quality in each zip code of a large urban county over a 40-year period.

Methods: We conducted a retrospective longitudinal study over 40 years in Wayne County, Michigan using socioeconomic and demographic data from …

Medicaid Expansion And Postoperative Mortality In Women With Gynecologic Cancer: A Difference-In-Difference Analysis, Sarah P Huepenbecker, Shuangshuang Fu, Charlotte C Sun, Hui Zhao, Kristin M Primm, Sharon H Giordano, Larissa A Meyer

Faculty, Staff and Student Publications

BACKGROUND: The association between Medicaid expansion and postoperative mortality after surgery for gynecologic cancer is unknown. Our objective was to compare 30- and 90-day postoperative mortality after gynecologic cancer surgery before and after 2014 in states that did and did not expand Medicaid.

METHODS: We searched the National Cancer Database for women aged 40-64 years old between 2010 and 2016 who underwent surgery for a primary gynecologic malignancy. We used pre/post and quasi-experimental difference-in-difference (DID) multivariable logistic regressions to evaluate mortality pre-2014 (2010-2013) and post-2014 (2014-2016) for states that did and did not expand Medicaid in January 2014. We completed …

Faculty, Staff and Student Publications

PURPOSE: Squamous cell carcinoma of the anus (SCCA) incidence and mortality rates are rising in the United States. Understanding state-level incidence and mortality patterns and associations with smoking and AIDS prevalence (key risk factors) could help unravel disparities and provide etiologic clues.

METHODS: Using the US Cancer Statistics and the National Center for Health Statistics data sets, we estimated state-level SCCA incidence and mortality rates. Rate ratios (RRs) were calculated to compare incidence and mortality in 2014-2018 versus 2001-2005. The correlations between SCCA incidence with current smoking (from the Behavioral Risk Factor Surveillance System) and AIDS (from the HIV Surveillance …

Influence Of County-Level Geographic/Ancestral Origin On Glioma Incidence And Outcomes In Us Hispanics, Kyle M Walsh, Corey Neff, Melissa L Bondy, Carol Kruchko, Jason T Huse, Christopher I Amos, Jill S Barnholtz-Sloan, Quinn T Ostrom

Faculty, Staff and Student Publications

BACKGROUND: Glioma incidence is 25% lower in Hispanics than White non-Hispanics. The US Hispanic population is diverse, and registry-based analyses may mask incidence differences associated with geographic/ancestral origins.

METHODS: County-level glioma incidence data in Hispanics were retrieved from the Central Brain Tumor Registry of the United States. American Community Survey data were used to determine the county-level proportion of the Hispanic population of Mexican/Central American and Caribbean origins. Age-adjusted incidence rate ratios and incidence rate ratios (IRRs) quantified the glioma incidence differences across groups. State-level estimates of admixture in Hispanics were obtained from published 23andMe data.

RESULTS: Compared to predominantly …

Extremism In America: Explaining Variations In Ideologically Motivated Fatal Violence, Celinet Duran

Dissertations, Theses, and Capstone Projects

This dissertation uses data from the United States Extremist Crime Database (ECDB) to assess the nature of extremist violence between left-wing, far-right and al-Qaeda and associated movements (AQAM) inspired ideological fatal violence. It extends the empirical literature on extremist violence in three significant ways by: (1) expanding an existing database to provide a comparative component that is both timely and policy-relevant and conveys a more complete picture of the nature of domestic extremism in the U.S.; (2) systematically comparing extremist violence across the left-wing, far-right and AQAM ideologies to better assess the nuances of extremist violence; and (3) applying empirical …

Western Corporations And Colombian Labor: Cycles Of Transhistorical Colonial And Economic Oppression In Colombia, Isabella Lazzarino-Buendia

Senior Theses

The relationship between colonial and colonized nations is entrenched in modern politics and history; remaining a transhistorical site of economic, social, and political imbalance. The United States and Colombia have a trans-colonial relationship that is shadowed by colonial gains at the expense of colonized livelihood. Western corporations mimic the patterns of the governments that preside over them, using the land and labor of the colonized “Other” to maximize profit. I investigate postcolonial Colombia through the lens of the transhistorical United Fruit Company and the mass corporation Coca-Cola. The accountability of these corporations and the systems that have allowed them to …

Unlocking Potential: The School-To-Prison Pipeline For Students With Disabilities, Navena F. Chaitoo

Dissertations, Theses, and Capstone Projects

This research uses quasi-experimental, matched sampling to examine the school-to-prison pipeline for students with disabilities using data from the National Longitudinal Study of Adolescent to Adult Health. This study presents novel insights into an at-risk group that has faced disproportionate rates of school discipline and incarceration. The study finds school suspension to be associated with future involvement in the criminal legal system and lower educational attainment. Disability was not found to mediate the relationship between suspension and future involvement in the criminal legal system or the relationship between suspension and academic outcomes. However, disability was found to be a statistically …

Man & Machine: A Narrative Of The Relationship Between World War Ii Fighter Advancement And Pilot Skill, Brian Burnett Ii

Browse all Theses and Dissertations

From 1938 until the end of World War II, the Curtiss P-40 fighter participated in the European, North Africa, and Pacific theaters of war. An aircraft’s success depends primarily upon the pilot’s expertise. Without skilled pilots, technology alone cannot win a war. Technological innovation still plays a crucial role in the success of a nation’s air force. Relative to technological developments, how impactful is a pilot’s skill on a fighter plane’s performance? My thesis structure is a deep look into each pilot’s experience and how victory was achieved with a plane that most military writings say is inferior. I investigate …

Monitoring American Federalism: The History Of State Legislative Resistance, Christian G. Fritz

Faculty Book Display Case

As Americans have monitored federalism, they struggled with how a government based on sovereignty divided between nation and states might function. The Constitution’s shared sovereignty created an inherently dynamic federalism with almost continuous debates over the balance of power, making this testing of the balance of federalism and monitoring government central to the American constitutional order. Many constitutional debates involved the protection of slavery, yet other interests including debt, taxation, and police powers also played vital roles in shaping American federalism. State resistance to the national government utilizing the constitutional tool of interposition arose when the disequilibrium of federalism was …

The Geographic Pattern And Socioecological Factors Of Helicobacter Pylori Infections In The United States, Judith Ann Merryweather

Walden Dissertations and Doctoral Studies

AbstractHelicobacter pylori (H. pylori) is one of the most common human pathogens and may play a role in the development of several distinct diseases, which include gastric ulcer, duodenal ulcer, and gastric cancer. Studying geographic territories of the United States may reveal clusters with high rates of H. pylori infection and perhaps the prevalence of gastric cancer; however, geographic mapping of patterns in the United States is scarce. The purpose of this study was to investigate changes in H pylori infection patterns in the United States between two different time points (2000–2002 and 2016–2018). The primary hypotheses of this study …

Grain-Washing: The Issue With Corn Ethanol As A Sustainable Aviation Fuel, Emily J. Rinn

Scripps Senior Theses

Decarbonizing the aviation sector remains one of the most prevalent obstacles in reducing the United States’ significant contribution to global greenhouse gas emissions. Launched in 2021, the Sustainable Aviation Fuel (SAF) Grand Challenge aims to supply enough fuel to meet 100% of demand by 2050 through reducing its production costs and enhancing its sustainable practices. Corn ethanol feedstock has been proposed to make up as much as half of all SAF production in the 2030 benchmark. This thesis explores the assemblage of corn ethanol – from its true environmental impacts, role in the future SAF market, to research claiming corn …

A Chinese Fallacy Of Communist Lynchpin And American Retort In Nepal, Ashis Adhikary

Himalayan Research Papers Archive

Why are Chinese and American activities escalating in Nepal? This research question frames the objective of this study. To opt for an answer, the paper delves into two distinct areas: the rise of Nepal’s communist forces and the corresponding influence of the Chinese Communist Party (CCP), and the historic role of America in curbing communism inside Nepal. It argues, the visible Chinese intent of forming a favorable communist power in Nepal, especially during and after the general elections of 2017, is a fallacy as it undermines American presence to limit the communist influence. Conceptually, the paper claims that the recent …

Racialization Of Muslim Students In Australia, Ireland, And The United States: Cross-Cultural Perspectives, Melanie C. Brooks, Miriam D. Ezzani Miriam D. Ezzani, Youcef Sai, Fida Sanjakdar

Journal Articles

The purpose of this qualitative cross-cultural case study was to better understand how Muslim students living in Australia, Ireland, and the United States navigated racism to identify ways in which school leaders and teachers can better address the structural, historical, and socioeconomic roots of racial injustice, discrimination, and ongoing oppression. Data collection was guided by a shared interview protocol that asked questions regarding family background, personal interests, identity, and friendships with a focus on their experiences of anti-Muslim racism in secondary schools. Findings suggested that Muslim students navigated racialization by (de)constructing their Muslimness, seeking voice, navigating between inclusion and exclusion, …

Situating Implementation Science (Is) In Res(Is)Tance: A Conceptual Frame Toward The Integration Of Scholarship From The Black Radical Tradition, Cory D Bradley, Whitney C Irie, Elvin H Geng

2020-Current year OA Pubs

This manuscript undertakes a disciplinary self-critique of the field of implementation science, a field which attempts to bridge the gap between evidence-based interventions and their practical application. Despite the heightened emphasis on health equity and racial disparities, the field's current discourse is limited by key epistemic shortcomings. First, even though prevalence of implementation gaps between racialized groups in the United States necessitates a comprehensive understanding of the systems perpetuating these disparities, the field does not operate with a general explanation for disparities not as a failure of systems, but a system historically and structural designed to produce disparities. Second, the …

A Bayesian Susceptible-Infectious-Hospitalized-Ventilated-Recovered Model To Predict Demand For Covid-19 Inpatient Care In A Large Healthcare System, Stella Coker Watson Self Ph.D., Ms, Rongjie Huang, Shrujan Amin, Joseph Ewing, Carolina Rudisill, Alexander C. Mclain Ph.D.

Faculty Publications

The COVID-19 pandemic has strained healthcare systems in many parts of the United States. During the early months of the pandemic, there was substantial uncertainty about whether the large number of COVID-19 patients requiring hospitalization would exceed healthcare system capacity. This uncertainty created an urgent need to accurately predict the number of COVID-19 patients that would require inpatient and ventilator care at the local level. As the pandemic progressed, many healthcare systems relied on such predictions to prepare for COVID-19 surges and to make decisions regarding staffing, the discontinuation of elective procedures, and the amount of personal protective equipment (PPE) …

Rejecting The Paradigm: Reimagining The Philosophy Of Punishment To Address The Criminal Justice Crisis In Twenty-First Century America, Jon E. Mcgee

Honors Theses

Legal punishment has been subject to cacophonous debate and transformation throughout the history of American political and philosophical discourse. As a growing body of academic literature indicates a failure in the punitive techniques practiced by American institutions, the necessity for a precise diagnosis of such ailments paired with a new model addressing American concerns for reform remains increasingly pertinent. With due consideration to the previous recommendations of scholars, this paper illustrates the crisis in criminal justice currently felt in the United States. Through statistical, theoretical, and comparative analyses, existing alternatives are examined and an alternative fit to serve the United …

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 …
