What School Leaders Need to Know: The Impact of Teacher Turnover on Student Achievement in Middle School Mathematics (open access)

What School Leaders Need to Know: The Impact of Teacher Turnover on Student Achievement in Middle School Mathematics

This study looked at the relationship between teacher turnover and student achievement, in addition to the relationship between specific student demographic characteristics and teacher turnover. Within this study, student demographic, staff demographic, and student achievement data from several middle schools within the studied district, as well as data from each of the school's comparison groups, as designated by the Texas Education Agency, was analyzed. The data used was from the 2018-2019, 2020-2021, and 2021-2022 school years. First, this study looked at specific student demographic characteristics and their relationship with teacher turnover, including race, mobility, and socioeconomic status. This analysis determined if there were specific variables that impacted the rate of turnover. Results determined that the most consistent relationship revealed in the data involves the total number of students on a campus. As the number of students increased, the turnover rate decreased. Additionally, there was a slight negative correlation between the number of African American students and rates of teacher turnover for two of the three years studied. The second part of the study determined if the campus turnover rate had any relationship with the student achievement scores. The student achievement data that was used was the overall campus math score …

Who are You Going to Believe: Me or Your Lying Eyes? Three Essays on Gaslighting in Organizations

In this dissertation, I theorize on how gaslighting manifests in managerial and organizational settings. I discuss the process of gaslighting and how the use of various manipulation tactics manifests between people in organizations over time. I take three distinctive approaches to study this complex phenomenon. First, using a rich case study, I develop new theory to explain how one notorious child molester was able to sustain a career for decades while assaulting hundreds of children and young women. In doing so, I introduce the concept of gaslighting which previously has only been rigorously applied to intimate interpersonal relationships in domestic (e.g., at home) settings. In essay 2, I expand on the individual level theory developed in essay 1 to develop a more generalized theory of gaslighting in organizations. I situate gaslighting within a nomological net of related constructs and illustrate how gaslighting is a unique construct with different antecedents and consequences that occurs in organizations more often than it should. In my final essay, I build on one of the propositions developed in essay 2 and empirically test what antecedents are likely to influence whether or not a firm is accused of gaslighting on Twitter. Through doing so, I find …

William Duckworth's "Southern Harmony": A Comprehensive Exploration into the Synthesis of Two Archetypal American Genres (open access)

William Duckworth's "Southern Harmony": A Comprehensive Exploration into the Synthesis of Two Archetypal American Genres

In his Southern Harmony collection, William Duckworth extracts existing material from shape-note hymns found in William Walker's 1835 publication A Southern Harmony and Musical Companion. He then applies minimalist and postminimalist processes to this material to create innovation choral compositions. This document provides a comprehensive analysis of the methods used to construct all twenty works in Duckworth's collection by tracing the extracted source material through the fabric of the new compositions. This study provides substantial evidence of Duckworth's place as a pioneer of the postminimalist genre. It also provides a discussion on the vocal implications of utilizing shape-note hymns as source material as traditional performances of the genre are typically associated with a unique vocal style.

Worker Displacement by Artificial Intelligence (AI): The Impact of Boundary-Spanning Employees

Limited literature examines the impact of the displacement of boundary-spanning employees artificial intelligence (AI). Scholars and practitioners appear focused on tangible benefits of AI adoption, and do not seem concerned by any less tangible and possibly untoward implications of worker (particularly boundary-spanning worker) displacement. My dissertation addresses this gap in the literature. In Essay 1, a qualitative study is performed to anchor the research on the appropriate ethnographic setting, the firms where this displacement phenomenon is taking place, by utilizing the Straussian grounded theory approach. The outcome of iterative coding of the first order data collected from the interviews and content analysis is a conceptual framework which amongst other findings shows how the unique competences of boundary-spanning employees and those of AI are best suited for different spectra of interorganizational collaborative activities. In Essays 2 and 3, I investigate major themes that emerged from Essay 1 utilizing quantitative and qualitative research methods in both studies. Initially I test research models using structural equation modelling on practitioner survey data, after which I probe further via focused interviews to better understand the survey results. The two papers allow us to put forth several theoretical and managerial contributions, specifically emphasizing the positive essential …

The World We Want to Leave Behind: White Supremacy in the Apocalyptic Genre's Past, Present, and Future

This dissertation examines the rise of the racialized apocalyptic genre from 1978 to 2019. The period chosen reflects the social shift of the American political right into a party that accepts white supremacy as a tenet. In the post-Civil Rights era, white Americans considered the issue of racism to be solved. With the historic Voting Rights Act and other major victories in the 1960s there was a moment when it seemed America may turn a corner. However, when Richard Nixon took office in 1969, he originated what would be a long process of positioning the American right against intellectualism, minorities, and progress. Nixon, and the development of the new southern strategy would reach decades into the future, utilizing coded language and pitting Americans against one another. Research examining the racialized elements of the American right from Nixon to contemporary times is well chronicled and vast.
