Cross-Species Real-Time Detection Of Trends In Pupil Size Fluctuation, Sharif I. Kronemer, Victoria E. Gobo, Catherine R. Walsh, Joshua B. Teves, Diana C. Burk, Somayeh Shahsavarani, Javier Gonzalez-Castillo, Peter A. Bandettini

Faculty Research, Scholarly, and Creative Activity

Pupillometry is a popular method because pupil size is easily measured and sensitive to central neural activity linked to behavior, cognition, emotion, and perception. Currently, there is no method for online monitoring phases of pupil size fluctuation. We introduce rtPupilPhase—an open-source software that automatically detects trends in pupil size in real time. This tool enables novel applications of real-time pupillometry for achieving numerous research and translational goals. We validated the performance of rtPupilPhase on human, rodent, and monkey pupil data, and we propose future implementations of real-time pupillometry.

An increasing number of studies find that water sharing—the non-market transfer of privately held water between households—is a ubiquitous informal practice around the world and a primary way that households respond to water insecurity. Yet, a key question about household water sharing remains: is water sharing a viable path that can help advance household water security? Or should water sharing be understood as a symptom of water insecurity in wait for more formalized solutions? Here, we address this question by applying Sen’s entitlement framework in an integrative review of empirical scholarship on household water sharing. Our review shows that when …

Collective Liberation Through Critical Pedagogy, Robert A. Marx, Anne E. Dufault, Miriam R. Arbeit

Faculty Research, Scholarly, and Creative Activity

The collective liberation of queer and trans people—which is inherently tied to the liberation of those oppressed by white supremacy and racism, ableism, classism, ageism, and other asymmetrical power distributions—is possible when we develop critical consciousness through critical pedagogy. As young people develop an awareness of the contradictions and falsehoods they are taught (e.g., the myth of meritocracy), they begin to work to change their environments and offer resistance to the structures that inequitably shape their world. The vast majority of research on queer and trans adolescents, though, has been shaped by dominant, deficit-based views of queerness that presuppose that …

Transit agencies often track delays and malfunctions but may overlook riders’ real-time social experiences. To fill this gap, we analyzed 559 tweets from 2020 to 2023 that captured personal accounts of public transport use. Using thematic analysis, we found that 74% of posts criticized other passengers’ behavior, far outweighing comments on transit ride quality, such as complaints about delays (25%). Notably, 86% of tweets expressed negative sentiment, though some highlighted exceptional service. These findings demonstrate that interpersonal dynamics are a key contributor to riders’ experiences and illustrate the nature of the interactions that riders like and dislike.
