A Novel Bayesian Spatial-Temporal Approach To Quantify Sars-Cov-2 Testing Disparities For Small Area Estimation, Cici Bauer, Xiaona Li, Kehe Zhang, Miryoung Lee, Esmeralda Guajardo, Susan Fisher-Hoch, Joseph Mccormick, Maria E Fernandez, Belinda Reininger

Faculty, Staff and Student Publications

Objectives. To propose a novel Bayesian spatial–temporal approach to identify and quantify severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) testing disparities for small area estimation.

Methods. In step 1, we used a Bayesian inseparable space–time model framework to estimate the testing positivity rate (TPR) at geographically granular areas of the census block groups (CBGs). In step 2, we adopted a rank-based approach to compare the estimated TPR and the testing rate to identify areas with testing deficiency and quantify the number of needed tests. We used weekly SARS-CoV-2 infection and testing surveillance data from Cameron County, Texas, between March 2020 …

Micropolitics Of Urban Informality And Street Vendors In Kolkata, Tathagata Chatterji, Archit Sinha, Atanu Chatterjee, Anjita Paul

Socio-Legal Review

Street vending activities received formal legislative recognition in India, with the Parliament enacting the Street Vendors (Protection of Livelihood and Regulation of Street Vending) Act in 2014. Since then, the judiciary has sought to uphold the rule based order through the implementation of the Street Vendors Act. However, on-ground implementation of the progressive legislation remains challenging, and vendors continue to face harassment. Looking through the prism of “political society”, this article explores micro-level network politics around street vending in Kolkata. First, it discusses how the city’s political economic context played a role in the mobilisation of the vendors to resist …

Social Studies Teachers’ Perceptions Of Alternative Assessments For Students With Ieps, Chander Mohan Mallhotra Jr.

Walden Dissertations and Doctoral Studies

Assessments are one of the vital pillars of education but often are designed without the specific needs of students considered. Instruction is often differentiated for students with individualized education programs (IEPs), but rarely are assessments. Students in classes with IEPs in the social studies department at the project site school in the state of New York are performing below grade level. Teachers at this school are encouraged by the department chair to structure their assessments based on the Regents exam, which uses traditional assessment methods. The purpose of this case study was to investigate the perceptions of teachers regarding the …

Racial Discrimination And Toxic Cultures At Work: Professional Black Employees And The Great Resignation, Annselmer Thomas Owens

Walden Dissertations and Doctoral Studies

AbstractWhite-collar Black employees were more likely to seek different jobs during the Great Resignation because of a lack of career advancement, employer failure to promote diversity, equity, and inclusion, employer’s unethical behavior, feeling disrespected, and perceived toxic work culture. As the Great Resignation’s professional, social, and ethical consequences were only emerging, scholars identified a literature gap to position Black employees’ narratives of racial discrimination and perceived toxic work culture in the literature as mechanisms for joining the Great Resignation. The purpose of this qualitative, narrative inquiry study was to gain a deeper understanding of how professional Black employees’ daily experiences …

Exercise Science Faculty Research and Publications

Previous observational work from 2020 demonstrated gender-, age-, and location-related differences in mask-wearing behavior, despite the efficacy and public health messaging that emphasized face coverings in combatting the spread of COVID-19. In 2021, COVID-19 vaccinations and a corresponding change in public health policy became new considerations in deciding personal protective behaviors. To provide an update on mask wearers and resistors approximately one year after our initial study, we observed shoppers (n = 6,118) entering retail stores using the same experimental methodology. Approximately 26% of individuals wore a mask. Mask wearing has decreased across demographic groups compared to 2020. Aligning …

Understanding The State Of Broadband Connectivity: An Analysis Of Speedtests And Emerging Technologies, Reinaldo Sanchez-Arias, Luis G. Jaimes, Shahram Taj

Electrical Engineering and Computer Science Faculty Publications

The lack of access to broadband services and speeds that allows urban and rural populations to meet the minimum requirements of today's society creates a lack of economic opportunities and digital inequality. In contrast, regions with adequate broadband infrastructure can attract investors and become the home of tech workers while boosting the local economy. To level the field and promote the expansion and improvement of broadband infrastructure, federal and state agencies in the U.S. provide funding through programs such as the Rural Digital Opportunity Fund, and The Enabling Middle Mile Broadband Infrastructure Program among others. Here, counties assess their broadband …

The Importance Of Exit Via Acquisition To Venture Capital, Entrepreneurship, And Innovation, Devin Reilly, D. Daniel Sokol, David Toniatti

Minnesota Journal of International Law, Vols. 28:2 onward (2019-present)

Antitrust regulators around the world, including in the UK, have proposed changes to merger review policies that impact how acquisitions of start-ups would be investigated and evaluated. Such changes will likely lead to heightened scrutiny—and increased costs and longer reviews—for many acquisitions, including both horizontal and non-horizontal mergers. In evaluating the merits of such changes, it is critical to take into account the important role that exit via acquisition plays in providing incentives for venture capital (VC) investment and entrepreneurship. This article seeks to provide context for evaluating the effects of such proposed changes. First, it documents the links among …

Quantifying The Economic Costs Of Global Warming, Christopher W. Callahan

Dartmouth College Ph.D Dissertations

Climate change poses a threat to the well-being of people across the globe. Rising global temperatures will increase the frequency and magnitude of extreme climate events, threatening the lives and livelihoods of vulnerable people. Yet the magnitude and persistence of these economic impacts are poorly understood, making it difficult both to design equitable mitigation and adaptation strategies and to hold emitters accountable for the impacts of their emissions. In this thesis, I combine methods from detection and attribution, climate projection, and causal inference to understand the global economic consequences of past and future climate change. I show that two extreme …

Hydrocephalus: A Neuropsychological And Theoretical Primer, Tara Zaksaite, Catherine Loveday, Trudi Edginton, Hugo J. Spiers, Alastair D. Smith

School of Psychology

Hydrocephalus is a common neurological condition, the hallmark feature of which is an excess in production, or accumulation, of cerebrospinal fluid in the ventricles. Although it is associated with diffuse damage to paraventricular brain areas, patients are broadly typified by a particular pattern of cognitive impairments that include deficits in working memory, attention, and spatial abilities. There have, however, been relatively few neuropsychological accounts of the condition. Moreover, theories of the relationship between aetiology and impairment appear to have emerged in isolation of each other, and proffer fundamentally different accounts. In this primer, we aim to provide a comprehensive and …

Sociophonetics And Dialectology, Dominic Watt, Margaret E. L. Renwick, Joseph A. Stanley

Faculty Publications

In this chapter we explore how the investigation of phonetic detail in speech seen through a sociolinguistic lens can inform and enhance our understanding of dialectal variation in languages. We begin by examining how sociophonetics can be considered an offshoot of dialectology, later to mature into a free- standing discipline during the late twentieth century. We next discuss the reconvergence of sociophonetics and dialectology as it became clearer that the two approaches to the study of language variation are, in combination, greater than the sum of their parts, even if their agendas may place different emphases on what should be …

Photojournalism, Public Health, And Politicization: Analyzing Photographic News Coverage Of Health Crises In The 20th And 21st Centuries, Hans C. Schmidt

Iowa Journal of Communication

While political division has been present in the American press since its start, politicized and polarized content is now stretching beyond straightforward political news – where such content might be expected – and is increasingly seen in other news categories, including science, medical, and health journalism. This development has been especially notable during the COVID-19 pandemic, when medical and health reporting frequently became coopted by a political narrative. This study builds on research into the politicization of pandemic and medical reporting with an investigation of pandemic-era photojournalism. Using a content analysis, this study aims to provide greater insight into the …
