Understanding and counteracting racial bias in policing

Kimberly Barsamian Kahn

23 Jan 2019, 7:30 pm

238 Smith Memorial Student Union

Portland State University

The lecture is open to the public and admission is free.

Police shootings of unarmed racial minorities prompted psychological research on race in policing in order to both understand and counteract potential bias. In this talk, I will discuss my research on the psychological effects of race and racial stereotyping on police behavior. I have conducted research with police departments across the country to study this issue, including with the Center for Policing Equity and local departments in Oregon. Using data from experimental, observational, correlational, and archival police case file studies, I detail how subtle forms of stereotyping, implicit bias, and identity related threats impact decisionmaking during police-community interactions. Analyses will examine both police and community member behavior during interactions, and how both parties can be influenced by subtle biases and psychological identity threats. These biases ultimately lead to an escalation in use of force during these interactions. Using this scientific information, I will discuss evidence-based interventions to reduce racial bias in policing behavior and how to promote more equitable outcomes for all community members.

Dr. Kimberly Barsamian Kahn is an Associate Professor of Social Psychology at Portland State University and leads the Gender, Race, and Sexual Prejudice (GRASP) research lab. She received her Ph.D. in Social Psychology from the University of California, Los Angeles and completed a postdoctoral fellowship at Lisbon University Institute in Portugal. Dr. Kahn’s research addresses contemporary forms of implicit bias and subtle prejudice from both the targets’ and perceivers’ perspectives. She has conducted empirical research and interventions to reduce implicit bias and stereotyping within education systems, work organizations, and police departments. Her work has been funded by the National Science Foundation, the Society for the Psychological Study of Social Issues, the Bureau of Justice Assistance, and the National Institute for Transportation and Communities.

Smart City PDX and Make+Think+Code (a program of the Pacific Northwest College of Art) invite you to a forum/conversation/unconference on civic data and digital/data privacy in our region on 17 January 2019, 12-30 –5:30 pm. In a digitally networked world, as more and more personal information is collected, shared, and used across a variety of contexts, we need tools and policies to safeguard privacy and anonymize data while ensuring transparency and open access to support research, advocacy, and civic innovation. This participant-driven meeting will create space to share opportunities, concerns, and challenges related to privacy and civic data in our region.

15th Annual SX-CW Student Research Presentations

16 November 2018

Sigma Xi Columbia-Willamette Chapter held its fifteenth annual Symposium of poster papers by undergraduate and graduate students in the sciences, social sciences, mathematics, and engineering on Friday 16 November 2018, at Portland State University in the Smith Memorial Student Union Ballroom. The posters-only Symposium is open to students affiliated with colleges and universities in the Portland area. Awards are given for the best undergraduate and graduate posters in several categories.

38 student research posters were reviewed by 22 judges, and 18 cash prizes for best poster presentation were awarded, including a special award to a high school student. The primary student authors were affiliated with 3 local academic institutions (PSU, UP, OHSU); in other years, students at Concordia, George Fox, and Linfield also exhibited their research. The Symposium provides practice for presentations at regional and national meetings in students’ own disciplines. The Symposium is open to the public, and admission is free.

Sigma Xi holds a worldwide competition for research grants to students in March and October every year. The next deadline to apply for a grant is 15 Mar 2018. The following local students recently earned GIARs for their projects. Each of them also received a modest supplemental grant from our chapter.

Kelsi Ramos, Chemistry: Characterization of Pre-Transition Droplets in Liquid-Liquid Systems with Magnetic-Susceptibility-Matched NMR Tubes. Advisor: J. Charles Williamson, Willamette University. (October 2017 competition)

Tetiana Korzun, Chemistry: Effects of Vaping on Ocular Health: Analysis of Selected Alcohols, Acids and Their Derivatives as Major, Yet Underestimated E-cigarette Vapor Toxicants. Advisor: Robert M. Strongin, Portland State University. (October 2017 competition)

The Sigma Xi Grants-in-Aid of Research (GIAR) program has been funding research by undergraduate and graduate students since 1922. Ninety-seven students who applied by the October 1, 2018, deadline learned that their proposals were accepted. Collectively, the students received $87,696. The awardees are from six countries. Of the 810 proposals received, grants were earned by 17 undergraduate students, 24 master’s students, and 56 doctoral candidates, including Portland-area master's students Madeline Lewis and Scott Kiel.

Previous GIARs have been earned by students at Portland State University, University of Portland, Washington State University Vancouver, and Willamette University. We encourage students at all academic institutions in the Portland area to apply. Membership in Sigma Xi isn't required, but 75% of the grants are reserved for student members and advisees of faculty members.

June 2018: the Chapter provided partial travel support for three students to present their research at the Sigma Xi NW/SW + AAAS Pacific Division Student Research Conference, at Cal State Pomona. Brie Tripp won first prize in the Pacific Division's Education Section; Tetiana Korzun won an honorable mention in the Cell and Molecular Biology Section; and Emmanuel Abdul found the Conference "very enriching and a tremendous opportunity to learn what other people are doing. It certainly was an eye-opener and a great learning experience for me as I gained insight into possible applications of my work on Vertically aligned polymer nanostructures functionalized by magnetron sputtering. Sigma Xi made the experience and professional networking with fellow growing scientists possible for me and for this, I am very grateful."

Fall 2017: Raluca Gosman, undergrad student in biology, presented her work at the Sigma Xi NW/SW + AAAS Pacific Division Annual Meeting at the University of Hawaii, and wrote: "This conference was a fantastic learning experience for me as I got helpful feedback from the oral presentation I gave about my work with Y-Chromosomal Short Tandem Repeat Analysis. Although I did not get as many results as I would have wanted, I felt encouraged that I was on the right track to keep trying, keep perfecting my techniques, and trust the scientific method of trial and error. Because a large portion of my project is yet to be completed, the interest my audience had in the final outcomes gave me new motivation to work hard and obtain results this coming year."

Anh Ngo at Sigma Xi Atlanta meeting, November 2016

Anh Ngo won the Graduate Student award in Cell Biology and Biochemistry at the Sigma Xi Annual Meeting in Atlanta, November 2016, for her poster presentation: Utility of a low-volume imaging assay to assess the granular phenotype and activity of neonatal platelets. She's a grad student at Oregon Health & Science University.

Srikar Rao Darmakkolla, who also presented his research at the Atlanta meeting, wrote: "I learned many things from this conference...key note lectures are my all time favorite... Unlike other conferences, this gave us great opportunity to mingle and improve our network."

Amie Romney at AAASPD/SX San Diego meeting, June 2016, with Jon Clark

Amie Romney won the first-place award in Cell and Molecular Biology, plus the President's Award, at the Sigma Xi NW/SW + AAAS Pacific Division Annual Meeting, San Diego, in June 2016, for her poster presentation: Epigenetic regulation of alternative developmental trajectories in an annual killifish. She's a PhD student in biology at Portland State University, and she's pictured at left with her former undergraduate advisor, Jon Clark, who attended the meeting as Sigma Xi Northwest Regional Director.

Quoting Amie, "I had an amazing experience at the 2016 AAASPD conference in San Diego. Through my newly-formed connections with Sigma XI, I was introduced to many wonderful people. Everyone there demonstrated genuine support for young researchers in scientific practice as well as career development. I would have never had such an opportunity to build a network of professional contacts. Thank you to everyone who made the trip possible for me!"

The Chapter provided partial travel support for the above students, and others, to present their research. Similar awards earned earlier by local students at regional and national Sigma Xi meetings are listed in Student Travel Awards.
