Intelligent Systems For Active Program Diagnosis, Haider Ali Ramadhan, Khalil Shihab

Sultan Qaboos University Journal For Science

Intelligent program diagnosis systems are computer programs capable of analyzing logical and design-level errors and misconceptions in programs. Upon discovering the errors, these systems provide intelligent feedback and thus guide the users in the problem-solving process. Intelligent program diagnosis systems are classified by their primary means of program analysis. The most distinct split is between those systems that are unable to analyze partial code segments as they are provided by the user and must wait until the entire solution code is completed before attempting any diagnosis, and those that are capable of analyzing partial solutions and providing proper guidance whenever …

The Effects Of Financial Giants In The Housing Market: A Study Of The Impact Of Private Equity And Institutional Investors During The 2008 Crisis, Kathryn Vaden Hughes

Harriet L Wilkes Honors College Theses 2020 - Present

The 2008 financial crisis revealed substantial vulnerabilities in the housing market and financial sector, in which private equity firms and institutional investors played an important role. This thesis analyzes the impact of Blackstone, KKR, Bain Capital, and Apollo Global Management on the housing bubble, speculative investments, and post-crisis strategies. Results suggest that systemic risks were enabled by leveraged acquisitions, subprime mortgage investments, and large-scale real estate speculation, and post-crisis asset acquisition enabled these firms to profit from market downturns. Although regulatory responses, such as the Dodd-Frank Act and the Volcker Rule, were enacted to help mitigate future crises, institutional investors …

Quantifying The Decline In Avian Biodiversity: A Global Crisis And Its Implications For Environmental Education, Canaline Osaka

The International Journal of Ecopsychology (IJE)

People care about what they love—and it’s easy to love--and fall in love, with birds. The

opportunities to promote bird diversity are legion, and applicable throughout K-12 education. For example, the Eastern Bluebird needs to nest in the cavities of dead trees, a habitat drastically denuded by large scale farming—or in specialized nesting boxes. A nationwide effort to build and install these boxes has brought the population back to healthy numbers since its 1970 low point. (Once one knows what they look like, one cannot miss these roadside homes—Western Bluebirds also benefit.) Students can also engineer bird houses and deters, …

Theorizing The Body In The Asl Interpreting Field: Promising Dimensions For Further Research, Taylor L. Woodall-Greene, Lucy E. Bailey

Journal of Interpretation

This paper theorizes body politics in the American Sign Language Interpreting profession. The field is facing problems with burnout and attrition. We focus on the interpreting body and present four themes, including the embodied demands, the limited available scholarship over “the body” in ASL, the fluctuating meaning of the interpreter’s bodily labor, and the educational implications of our analysis. We argue that attention to body politics matters, and more research is needed on the intersections between the body and the ASL interpreting profession. Continuing the research into these theoretical dimensions and interpreters’ self-care given the embodied demands of the profession, …

Academic Freedom In Interpreter Education: Teaching Communication Access In A Culture Of Censorship, Dawn M. Wessling, Mark A. Halley, Brendan Stern

Journal of Interpretation

Abstract

The primary function of signed language interpreters and translators is to foster inclusion and equity by ensuring effective communication access for deaf individuals from diverse linguistic backgrounds in public spaces. The effectiveness of interpreter education depends on the freedom of expression, thought, and behavior. This paper explores the impacts of illiberal legislation on American Sign Language/English interpreter education in Florida. Specifically, we describe how the illiberal attacks on academic freedom that preclude Diversity, Equity, and Inclusion (DEI) initiatives and curricula, such as Florida’s SB266/HB999 (2023) and SB2525/HB7 (2022), present unprecedented challenges for interpreter and translator educators. In conclusion, we …

Everything But Wrestling: How Women Wrestlers Perform Dominance, Lauren Gherman

Anthropology Honors Papers

Women’s wrestling continues to grow at the high school level, with more young girls joining the sport each year. Yet, as more women join wrestling, a heavily masculine sport, questions about gender preintimation on women’s teams arise. This study asks three questions about the role of gender on women’s teams: 1) Does an individual’s gender identity, in a heavily gendered sport like wrestling, factor into the development of team culture? 2) What, if any, forms of gendered socialization emerge as women enter wrestling? 3) In what way are women socialized because of their gender? Data was gathered via interviews, in …
