The Imposter Among Us: How Imposter Syndrome Is Fueled By Diversity Discourses, Tina Liu

Urban Library Journal

In this paper, first presented at the 2023 LACUNY Institute, the author discusses definitions of imposter syndrome and how imposter syndrome fits within the diversity model. The diversity model, as used in this paper, emerges from an oversimplified framing of racial inequity as a problem that is solved by simply hiring diverse bodies to appear inclusive. In conjunction with the proliferation of imposter syndrome in post-secondary institutions, the ongoing phenomenon of imposter syndrome among librarians and academics reveals an underlying systemic problem rather than individual shortcomings. Workplace discomfort in post-secondary institutions is too easily brushed off as imposter syndrome, without …

Effects Of Dimerization On The Deacylase Activities Of Human Sirt2., Jie Yang, Nathan I Nicely, Brian P Weiser

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Human sirtuin isoform 2 (SIRT2) is an NAD+-dependent enzyme that functions as a lysine deacetylase and defatty-acylase. Here, we report that SIRT2 readily dimerizes in solution and in cells and that dimerization affects its ability to remove different acyl modifications from substrates. Dimerization of recombinant SIRT2 was revealed with analytical size exclusion chromatography and chemical cross-linking. Dimerized SIRT2 dissociates into monomers upon binding long fatty acylated substrates (decanoyl-, dodecanoyl-, and myristoyl-lysine). However, we did not observe dissociation of dimeric SIRT2 in the presence of acetyl-lysine. Analysis of X-ray crystal structures led us to discover a SIRT2 double mutant (Q142A/E340A) that …

Is Your Computer Lying? Ai And Deception, Noreen L. Herzfeld

Reuter Professorship of Science and Religion Publications

Recent developments in AI, especially the spectacular success of Large Language models, have instigated renewed questioning of what remains distinctively human. As AI stands poised to take over more and more human tasks, what is left that distinguishes humans? One way we might identify a humanlike intelligence would be when we detect it telling lies. Yet AIs lack both the intention and the motivation to truly tell lies, instead producing merely bullshit. With neither emotions, embodiment, nor the social awareness that leads to a theory of mind, AIs lack the internal referents on which to judge truth or falsity. When …
