Leveraging body-worn camera footage to assess the effects of training on officer communication during traffic stops.

Can training police officers on how to best interact with the public actually improve their interactions with community members? This has been a challenging question to answer. Interpersonal aspects of policing are consequential but largely invisible in administrative records commonly used for evaluation. In this study, we offer a solution: body-worn camera footage captures police-community interactions and how they might change as a function of training.

Toward Quantitative Neurology: Sensors to Assess Motor Deficits in Dementia.

Background: Alzheimer's disease (AD) is the most common neurodegenerative disorder which primarily involves memory and cognitive functions. It is increasingly recognized that motor involvement is also a common and significant aspect of AD, contributing to functional decline and profoundly impacting quality of life. Motor impairment, either at early or later stages of cognitive disorders, can be considered as a proxy measure of cognitive impairment, and technological devices can provide objective measures for both diagnosis and prognosis purposes.

People who share encounters with racism are silenced online by humans and machines, but a guideline-reframing intervention holds promise.

Are members of marginalized communities silenced on social media when they share personal experiences of racism? Here, we investigate the role of algorithms, humans, and platform guidelines in suppressing disclosures of racial discrimination. In a field study of actual posts from a neighborhood-based social media platform, we find that when users talk about their experiences as targets of racism, their posts are disproportionately flagged for removal as toxic by five widely used moderation algorithms from major online platforms, including the most recent large language models. We show that human users disproportionately flag these disclosures for removal as well.

Relationship between Health Literacy and Proper Antibiotic Use Awareness in Tehran 2019-2020.

Background: Improper use of antibiotics is one of health care problems that can lead to side effects or antibiotic resistance without benefit. This study aimed to evaluate the association between health literacy and knowledge on appropriate use of antibiotics in a population sample from Tehran.

The benefits of difference-education interventions in lower-resourced institutions.

Difference-education is an intervention that addresses psychological barriers that can undermine the academic performance of first-generation college students (i.e., those who have parents without 4-year degrees).
