The Pilling Process: Significance Quest, Self-Verification, And Fusion In Online Incel Forums, Gregory J. Rousis

USF Tampa Graduate Theses and Dissertations

Incels (short for “involuntary celibates) are an online community of men who blame women for their reputed sexual and romantic failures. The misogyny of their worldview, called the blackpill, has inspired multiple instances of real-world violence against women. Alarmingly, we know little about the temporal processes whereby an incel goes from joining an online community to becoming deeply aligned (i.e., “fused”) with the group. This project sought to address this by scraping incels’ most popular web forum and using text analysis to identify psychological mechanisms that could be responsible for incels’ fusion. The resulting dataset consisted of 1,097,841 unique discussion …

Therefore, a continuous engaging plan to advance entrepreneurial success is needed to grow a small business.

My research objective aims to find methods and designs, through academic literature and practitioner interviews, that transition leadership responsibilities and increase team empowerment within a small business, enabling these firms to continue growing as the …

The Use Of Developmental Program Evaluation For State Continued Approval In Educator Preparation, Suzanne L. Roberts

USF Tampa Graduate Theses and Dissertations

Working as a teacher educator today means working under an ever-present regulatory gaze. Accountability mechanisms, including state program approval processes, have been layered resulting in complexity. External assessments have failed to provide the data needed to support continuous improvement. There have been calls for combining external and internal evaluation processes to better drive continuous improvement. Developmental Program Evaluation (DPE) is an approach that claims to support program development in the middle space between top-down and bottom-up forces. This study examines the use of DPE in the middle space between mandated state approval processes and a small educator preparation program’s effort …

A School Leader’S Experiences With Ableism In An Educational System, Scottie Basham

USF Tampa Graduate Theses and Dissertations

The current organizational autoethnographic study aims to problematize ableism as an ideology that permeates and contributes to the inequities students with disabilities face in education. I share how I came to see ableism as an ideology that permeates and contributes to recursive practices in special education and share experiences that illustrate to school leaders ableist assumptions that are ingrained in leading a Special Education Center. Using organizational autoethnography, I share my experience as a first-year principal to provide a first-hand account of recursive practices within the educational organization, rooted in ableism, and discuss how those practices affected both myself, as …

Expanding On The Factor Structure And Construct Validity Of The Short-Term Assessment Of Risk And Treatability (Start), Haomin Chen

USF Tampa Graduate Theses and Dissertations

Research finds better reentry/recidivism program outcome when individuals receive service that matches their risks and needs. It is thus essential to measure recidivism risks and needs appropriately. The Short-Term Assessment of Risk and Treatability (START) is a clinically-oriented instrument that assesses risks of future violence/offending and identifies areas for treatment. We see its potential use as an assessment tool for reentry/recidivism programming. More empirical evidence is needed to identify the psychometric properties of the instrument in this setting before it may be used in practice. The current thesis explored the factor structure of the START strengths and vulnerabilities scales using …
