Deconstructing Standard English Ideology: Elements Of Equitable And Inclusive Language And Literacy Education For Our Times, Gricelda Carbajal

Electronic Theses, Projects, and Dissertations

ABSTRACT

This thesis argues for the deconstruction of the standard English ideology, which holds that standard English is inherently superior to other English varieties. It examines the ideology’s detrimental effects on those who speak and use nonstandard English varieties, mostly minorities and people of color, who are linguistically profiled and marginalized because of the ways they speak. The ideology can also generate intensified reactions to perceived grammar and usage errors in those who subscribe to its prescriptivist views, and can promote judgments and stereotypes which impede communication and connection between people. To help dismantle the standard English ideology, the author …

Setting Events And Their Effects Upon Students' Behavior Goals, Linnea Hilderbrand

Electronic Theses, Projects, and Dissertations

This study investigates the impacts that setting events have upon the behavioral outcomes of students on a Check-In, Check-Out (CICO) intervention. Research was conducted through participant interviews each day, which were then translated into quantitative graphs for data analysis. The analysis has shown that there is not a significant correlation between the setting events studied and student behavioral outcomes. Although it was not statistically significant, there appeared to be some degree of correlations. Quantitative data shows that the effects of setting events upon each individual student are varied, which allows us to conclude that the effects of setting events upon …

Where The Ancestors Sleep: Radiocarbon Dating Of Bioapatite From La Consentida, Oaxaca, Robert Mitchell

Electronic Theses, Projects, and Dissertations

This study aims to refine the chronology of the burial sequence at the Early Formative Period (2000–1000 BCE) site of La Consentida in Oaxaca, Mexico. Previously, the chronology of mortuary spaces at La Consentida was supported by nine radiocarbon dates (2020–1510 cal BCE) from secure contexts, including charcoal, carbonized material from pottery, and two human bone samples processed together using R_combine to establish a single direct date for human remains at the site. This thesis study dated bioapatite from nine sets of adult human remains found in the two known mortuary contexts at La Consentida and two carbon-rich sediment samples …

(Wp 2024-03) The Dynamic Temporal Sequence And Reflexive Adjustment Behavior: Foundations For A Behavioral Alternative To Optimization Theory, John B. Davis

Economics Working Papers

This paper discusses the difference between mainstream and heterodox economics in terms of philosophy’s distinction between two types of temporal sequences governing events: the static, truth-tenseless before-after sequence and the dynamic, truth-tensed past-present-future sequence. Mainstream theory and optimization analysis employs the first. However, Aristotle showed long ago this implies fatalism. Heterodox explanations employ the second, which I argue implies people reflexively adjust their choices over time in a combined backward-looking and forward-looking way that rules out optimization. Central to this explanation of behavior is how uncertainty about the future is connected to uncertainty about the past. I show this can …

Impact Of Medicaid Redetermination On Underserved Populations In Region 7 States: A Review, Brianna Parr

Capstone Experience: Master of Public Health

When the COVID-19 Public Health Emergency ended in May of 2023, Medicaid began the process of redetermination across the states and returned to its original eligibility rules. Because of this, the healthcare status of many Americans was affected, resulting in the loss of healthcare coverage for millions of people. Of those who have lost coverage, children make up almost half of the total. This paper assesses the negative effects of Medicaid redetermination on children and other underserved populations in communities across the four states in Region 7 (Nebraska, Iowa, Missouri, and Kansas) and identifies programs that these states can implement …

Non-Tnfi Biologic And Targeted Synthetic Dmards In Rheumatoid Arthritis-Associated Interstitial Lung Disease: A Comparative, Propensity Score-Matched Study Using National Veterans Affairs Data, Halie E. Frideres

Capstone Experience: Master of Public Health

Background/Objectives: There is a paucity of evidence on the safety and effectiveness of non- TNFi biologic therapies in RA-ILD, this study aimed to compare treatment outcomes in RA-ILD between rituximab, abatacept, IL-6i, and JAKi using the Target Trial Emulation Framework.

Methods: We emulated 3 trials comparing abatacept, IL-6i, and JAKi with rituximab (reference). Patients fulfilling validated RA-ILD algorithms initiating one of these non-TNFi b/tsDMARDs were propensity score (PS)-matched (1:1) using national Veterans Affairs (VA) data from 2006 to 2020. PS models included demographics, comorbidities, general health status indicators, and RA- and ILD-related severity measures. Study outcomes were death and respiratory-related …
