A Multilayer Network Model Of The Coevolution Of The Spread Of A Disease And Competing Opinions, Kaiyan Peng, Zheng Lu, Vanessa Lin, Michael R. Lindstrom, Christian Parkinson, Chuntian Wang, Andrea L. Bertozzi, Mason A. Porter

School of Mathematical & Statistical Sciences Faculty Publications

During the COVID-19 pandemic, conflicting opinions on physical distancing swept across social media, affecting both human behavior and the spread of COVID-19. Inspired by such phenomena, we construct a two-layer multiplex network for the coupled spread of a disease and conflicting opinions. We model each process as a contagion. On one layer, we consider the concurrent evolution of two opinions — pro-physical-distancing and anti-physical-distancing — that compete with each other and have mutual immunity to each other. The disease evolves on the other layer, and individuals are less likely (respectively, more likely) to become infected when they adopt the pro-physical-distancing …

Processing Binding Data Using An Open-Source Workflow, Errol L G Samuel, Secondra L Holmes, Damian W Young

Faculty, Staff and Students Publications

The thermal shift assay (TSA)—also known as differential scanning fluorimetry (DSF), thermofluor, and Tm shift—is one of the most popular biophysical screening techniques used in fragment-based ligand discovery (FBLD) to detect protein–ligand interactions. By comparing the thermal stability of a target protein in the presence and absence of a ligand, potential binders can be identified. The technique is easy to set up, has low protein consumption, and can be run on most real-time polymerase chain reaction (PCR) instruments. While data analysis is straightforward in principle, it becomes cumbersome and time-consuming when the screens involve multiple 96- or 384-well plates. There …

Preserving Innocence: Ending Perceived Adultification And Toxic Masculinity Toward Black Boys, Erik M. Hines, Edward C. Fletcher Jr., Donna Y. Ford, James L. Moore Iii

Journal of Family Strengths

As early as the age of ten, Black boys are viewed as older, guilty until proven innocent by law enforcement (including school resource officers), and encounter a myriad of adverse racialized academic and social experiences (e.g., explicit and implicit biases) (Goff et al., 2014; Noguera, 2008). Dancy (2014) noted how Trayvon Martin, a Black male teen murdered for essentially being seen as threatening and intimidating, was viewed as adult-aged, deviant, troubled, and shiftless. Moreover, Black boys are expected to express minimum “signs” of weakness, vulnerability, and/or sensitivity. The aforementioned social persona may contribute to young Black men and boys not …
