The Social Studies Curriculum in Atlanta Public Schools During the Desegregation Era
This historical investigation explores how teachers, students, and education officials viewed the social studies curriculum in the local context of Atlanta, and the broader state of Georgia, during the post-Civil Rights era, when integration was a court-ordered reality in the public schools. During the desegregation era, Atlanta schools were led by Atlanta Public Schools (APS) Superintendent, Dr. Alonzo Crim. Brought to Atlanta as part of a desegregation compromise, Dr. Crim became APS\u27s first African American superintendent. In particular, the authors investigate how national social studies movements, such as Man: A Course of Study (MACOS), inquiry-based learning, co-curriculum activities, and standards movements, adapted to fit this Southeastern locale, at a time when schools were struggling to desegregate. Local curriculum documents written in the 1970s reveal a traditional social studies curriculum. By the 1980s, APS\u27s social studies curriculum guides broadened to include a stronger focus on an enacted community—inside the classroom and around the world. In oral history interviews, however, former teachers, students, and school officials presented contrasting perspectives of how the social studies curriculum played out in the reality of Atlanta\u27s public schools during the desegregation era
Trustworthiness in networks: A simulation approach for approximating local trust and distrust values
International audienceTrust is essential for most social and business networks in the web, and determining local trust values between two unfamiliar users is an important issue. However, many existing approaches to calculating these values have limitations in various constellations or network characteristics. We therefore propose an approach that interprets trust as probability and is able to estimate local trust values on large networks using a Monte Carlo simulation method. The estimation is based on existing indirect trust statements between two unfamiliar users. This approach is then extended to the SimTrust algorithm that incorporates both trust and distrust values. It is implemented and discussed in detail with examples. Our main contribution is a new approach which incorporates all available trust and distrust information in such a way that basic trust properties are satisfied
