BISR meaning in Academic & Science ?

Brooklyn Institute for Social Research (BISR), founded in 2012, is a non-profit interdisciplinary education and research institute based in New York City that offers university-style seminar classes, primarily in the humanities and social sciences, to adult learners. Alongside classes, BISR supports public research, programs with labor, non-profit, and activist organizations, and independent scholarly work outside the university. BISR is not a traditional degree-granting educational institution; rather, students enroll on a per-course basis to learn about topics that interest them. BISR classes typically take place in the evenings in a variety of public spaces, including museums, bars, bookstores, and community spaces. Faculty are advanced critical scholars dedicated to teaching and research in the public sphere.
