A Brief Look At Authoritarianism And Totalitarianism Through A Perspective Of Jewish Law And Tradition, Samuel J. Levine

Scholarly Works

A view of authoritarianism and totalitarianism through a perspective of Jewish law and tradition might take various forms and draw upon different approaches, depending on a number of components, including definitions of terms, modes of analysis, and the scope of disciplines and materials to be incorporated. Rather than attempting to present a comprehensive or determinative presentation of historical and philosophical considerations of these issues, this essay will briefly explore conceptual lessons from narrative, political, and legal sources of Jewish tradition, suggesting that Jewish thought recognizes, at once, both the importance of unity and authority and the dangers of authoritarianism and …

You Get The Jury You Get And You Don’T Throw A Fit, Taurus Myhand

Scholarly Works

The proliferation of deepfake videos has resulted in rapid improvements in the technology used to create them. Although the use of fake videos and images is not new, advances in artificial intelligence have made deepfakes easier to make and harder to detect. Basic human perception is no longer sufficient to detect deepfakes. Yet, under the current construction of the Federal Rules of Evidence, trials judges are expected to do just that. Trial judges face a daunting challenge when applying the current evidence authentication standards to video evidence in this new reality of widely available deepfake videos.

Filipinx Americans In U.S. Higher Education: A Mixed-Methods Critical Study Of Student Engagement Using The Culturally Engaging Campus Environments Model, Gerald Ariston Doton Corporal

Educational and Organizational Learning and Leadership Dissertations

Who are Filipinx American college students and what are their experiences in U.S. higher education? The academic literature emphasizes the importance of disaggregating empirical data on sub-populations within the Asian American and Pacific Islander racial diaspora to fully understand their experiences in a variety of contexts (Teranishi et al., 2015). In higher education administration, there is limited empirical data on Asian American and Pacific Islander college students and it is further limited when examining specific racial subgroups, such as Filipinx Americans (Museus & Maramba, 2011). This has implications for administrators in U.S. postsecondary institutions, particularly regarding their capacity to appropriately …
