Reimagining Hunting Through Women's Decision Space, H. Nash Jackson

Electronic Theses and Dissertations

Approximately 14.4 million people hunt in the United States, yet only 3.1 million (22%) of these hunters are women. To enhance women’s participation, many state natural resource agencies aim to reduce barriers and create pathways for women to hunt. Previously, researchers surveyed women to understand and describe barriers to their full participation in hunting. However, this methodology often just quantifies the different barriers without describing the interconnectedness and how the complexity of barriers can impact women’s participation in hunting. This thesis instead took an inductive research approach with the goal of better understanding women’s perspectives when faced with complex barriers. …

Comparative Analysis Of Deep Learning-Based Anomaly Detection Models For Gps Spoofing Detection, Hasan Mirzakhaninafchi

Electronic Theses and Dissertations

The Potential Of Humor To Joyously Dismantle Ableism+: Considerations For Social Workers, Mia Ocean

The Journal of Sociology & Social Welfare

Social workers are often well-positioned but not adequately equipped to disrupt, unsettle, or counteract ableism. Humor is one approach to disability justice work that can move the social work profession forward in a novel way. Within this practice brief, I use first-person narrative to illustrate the potential and limitations of humor to dismantle ableism+ in everyday interactions between social workers, clinical social work practice, and policy transformation. First, I share an example of how to use humor as a direct, call-in strategy to confront social worker-initiated ableist interactions. Second, I describe how a mixed disabled/abled couple can laugh together at …

A Path Wayward: Resisting “Evidence-Based” Discourse In Favor Of Critical Access, Engaged Relational Pedagogy And A Politicized Somatics, Erin Elizabeth Hipple, Nev Jones

The Journal of Sociology & Social Welfare

In contemporary MSW programs in the United States, clinical and mental health coursework frequently centers evidence-based practices (EBPs), communicates and explains problems of living (“psychopathology”) through the narrow lens of the APA Diagnostic and Statistical Manual (DSM), and rarely provides students with a deeper critique of the recalcitrantly medicalized mainstream of psychiatric services and interventions. In spite of a rich history of ecological thinking in social work, these increasingly dominant approaches foreground diagnosis and biopsychological treatments, stripping experiences of distress and/or mental diversity of their sociocultural contexts and promoting practices that implicitly locate primary problems at the level of the …

Call To Action: Disability Justice As A Framework To End Punishment Of And Advance Liberatory Education For Disabled Students, Jacy Hornsby, Jelena Todic

The Journal of Sociology & Social Welfare

The absence of disabled students in higher education, including social work, is a problem not only because of the missed educational opportunities and adverse effect on their earning potential but because disabled people’s knowledge, lived experiences, and skills can enhance social work services, advance innovation in knowledge production, and contribute to transformative organizational and movement leadership. School punishment, including suspensions, expulsions, and arrests, contributes to the absence of disabled people in higher education and begins as early as preschool. However, even for disabled students who graduate from high school and enroll in higher education, punishment continues covertly throughout higher education. …

Counting Is Hard! A Theory Of Doctrinal Expansion, Kip Hustace

Faculty Articles

We conventionally see pleading as liberalized, with leeway for inconsistent claims and expansive choice among theories of relief, or counts. Yet procedure scholars have shown how heightened pleading post-Twiqbal constricts liberality, turning us back toward 19th Century fact-intensive code pleading. This Article theorizes a further constriction: proliferating and ossifying counts. While affording pleading latitude, doctrinal expansion forces hard strategy decisions and represents an inversion of the maxim that procedure shapes substance. Expansion increases system complexity, making localized strategy and discretion more impactful and amplifying opportunities for juridical manipulation. The result: doctrines complexifying toward a tipping point, beyond which we make …
