Race Dynamics And Mentoring Experiences Of Aspiring Black Principals, Tiwana Richardson Meggett

Theses and Dissertations

This study aimed to investigate the dynamics of race and mentorship while capturing the lived experiences of Black principals as they were in the pipeline to the principalship. Although America’s public schools are becoming increasingly more diverse with students of color, the number of principals of color is relatively low; Blacks account for 10.7 % of the principalship, while whites account for 68.1% (School Principal Demographics and Statistics in the US, 2022). This qualitative study used Critical Race Theory (CRT) as a framework to inform the reader of racial trends, dynamics and/or thematic parallels of the participants in the study. …

Causes And Consequences Of The Risk Of Generalizability Biases In Health Behavioral Interventions, Lauren Von Klinggraeff

Theses and Dissertations

Preliminary testing of health behavior interventions (e.g., pilot, feasibility studies) are used to evaluate intervention viability prior to additional testing and resource investment (e.g., larger trials). This initial testing provides valuable information, but promising estimates of effectiveness produced during early testing are rarely reproduced in larger studies, stalling the development of effective, scalable health interventions. In the obesity intervention literature, external validity biases, features of the intervention that are not (or cannot) transfer to the larger study, are associated with these diminished effects. These study features, such who delivers the intervention, the characteristics of the population receiving the intervention or …

Particle-Free High Spatial Resolution Velocimetry For Slip Flow Detection, Malhar Prasad Joshi

Theses and Dissertations

Microfluidic systems have a wide range of applications, including biomedical devices, lab-on-a-chip technologies, and aerospace propulsion. Understanding and quantifying the slip flow phenomenon in these microscale and nanoscale channels is of paramount importance for precise control and optimization of fluidic processes. Our study presents a novel approach to directly measure the velocities in a microchannel using Laser Induced Fluorescence Photobleaching Anemometer (LIFPA) and Travel Time After Photobleaching Velocimetry (TTAPV). In this experimental study, microchannels with micrometer dimensions were used, and slip flow conditions controlled. The LIFPA-TTAPV approach was applied to measure slip velocities in the near wall regime, providing accurate …

Tip Of The Iceberg In Changing School Culture: Acknowledging And Addressing Microaggressions, Nicole Lauren Becker

Theses and Dissertations

Providing a culturally responsive learning environment that allows students and faculty to feel safe and welcomed is essential. This action research study examined the harmful impact of microaggressions in the school and how providing targeted and comprehensive professional development sessions helped faculty members be able to acknowledge and address microaggressions. The research study was conducted in a large elementary school in the northeast United States that serves approximately 800 students. The researcher worked with the school administration team to identify microaggressions as a problem of practice. The focus group interviews, and six-week professional development series aided in the participants’ journey …

Complex Stereotypes: Stereotypes Across The Intersections Of Gender, Sexuality, Age, Race/Ethnicity, And Social Class, Nicholas Heiserman

Theses and Dissertations

Research on stereotypes and their consequences often focuses on discrete categorical stereotypes in isolation from each other (e.g. gender or race categories), and rarely centers the fact that people belong to many social categories at once (e.g. gender and race categories). I address this issue using two large factorial experiment (N=1,762 and N=1,481) designed to measure two core aspects of stereotypes, warmth and competence, across the intersections of multiple social categories: Gender, Sexuality, Age, Race/Ethnicity (Chapter 3), and Social Class (Chapter 2). In Chapter 2, I develop a framework for analyzing intersectional complexity in these data, beginning with overall measures …

Animal Representation Of Race In The Princess And The Frog, Tiffany Tyantyan Enoch

Theses and Dissertations

Disney’s 2009 film The Princess and the Frog was created in response to racial criticism. It features the first Black princess as a means of promoting racial equality. This film attempts to positively portray Black characters, who were depicted as violent and lazy in previous animations.

While the film showcases positive themes (e.g., internal beauty and virtuous work) and portrays Black characters in a more positive light than previous films, it still perpetuates the typical racism against people of color. The lack of accurate and equal representation of racial groups in recognizable and famous stories is a persistent issue, and …
