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

The prevention of doping and the improper use of drugs and food supplements in sports and physical activities: a survey on the activity of the prevention departments of Italian local health authorities

INTRODUCTION: Doping is an important public health problem widespread not only among elite athletes, but also among amateur and recreational athletes and the general population. In Italy the introduction of doping prevention within the Essential Levels of Care (LEA) with the DPCM 12/1/2017 represents a crucial step towards the implementation of education and health promotion interventions. In this context, the Departments of Prevention (DP) of the Local Health Authorities (LHA) have to play a fundamental role, becoming the cultural and operational reference on this issue. As part of the "Doping prevention: development of a permanent educational tool coordinated by the National Health Service Prevention Departments" project, funded by the Italian Ministry of Health, a survey was conducted on the activities carried out by the DP regarding doping prevention and improper use and abuse of drugs and food supplements in sports and physical activities, as a basis for the harmonization of organizational structures and prevention programs and the creation of a collaboration network at a regional and national level. METHODS: A semi-structured questionnaire consisting of 11 questions, prepared on an electronic platform, was sent to the DP of all the Italian LHA. RESULTS: A total of 38 DP out of 131 (29%) completed the questionnaire, with representation from all regions. 42.1% of DP carried out or are still running programs for the prevention of doping, a percentage that decreases to 27% considering the programs for the prevention of misuse and abuse of drugs and food supplements in sports and in physical activities; in less than half of the DP, 37.5% and 41.7%, respectively, dedicated funds have been allocated. The professionals most involved in prevention of doping are the Specialists in Sport Medicine (81.3%) followed by Specialists in Hygiene (43.8%) and Psychologists (37.5%), while Health Care Assistants (50%) are the professionals most involved in the prevention of the improper use of drugs and food supplements, followed by Specialists in Hygiene and Specialists in Sport Medicine (40%). Most of the DP (71.9%) believe that the introduction of programs to prevent and counteract doping in the LEA will have repercussions on their approach against doping. CONCLUSIONS: The survey, although conducted on a limited sample, has provided an important framework relating to programs for the prevention of doping and the misuse and abuse of drugs and food supplements in sports and in the physical activities carried out by DP. A remarkable heterogeneity has been highlighted, both at national and regional level. It is urgent to provide DP with homogeneous and effective organizational models and adequate operational tools, paying particular attention to the training of all the professionals involved. It is also essential to implement permanent monitoring tools

Ordered arrays of Au nanoclusters by TiOx ultrathin templates on Pt(111)

Ultrathin ordered films of TiOx (x~1) on Pt(111) has been investigated by scanning tunneling microscopy (STM) to test their capability as templates for growing ordered and monodispersed Au nanocluster arrays. The ordered array of parallel black troughs spaced by 1.44 nm, observed in the STM data of the zigzag-like TiOx ultrathin film, revealed to be a good template for growing a linear array of Au clusters, with a mean size of 1.3 nm and a narrow dispersion. The wagon-wheel-like TiOx film, having similar chemical composition but without a nanostructured array of defects, does not show templating effects, leading to nucleation of disordered and larger Au clusters (mean size of 3.4 nm with a large dispersion). Hence this work shows that the ordering of the deposited Au nanoclusters is strongly dependent on the actual defectivity of the film. Annealing the Au cluster arrays at high temperature produces drastic changes in the spatial arrangement of the clusters, which has been interpreted as the consequence of the changes in the ultrathin film template
