I will briefly discuss what we have done to optimize the VICAR3D codes developed by the PI's group through this ECSS project. This includes those standard procedures we usually do in this kind efforts such as profiling code performance characteristics, sorting out the performance glitches, reorganizing the data domain decomposition, making the code more efficient in parallel, examining the performance portability when applying the code on architectures from Sandy Bridge and Knights Corner on Stampede1 to Knight's Landing on Stampede2. I would also like to share some interesting collisions and pleasant collaborations with the PI during the project and the lessons we learned.

Social construction is a theoretical position that social reality is created through the human's definition and interaction. As one type of social reality, juvenile delinquency is perceived as part of social problems, deeply contextualized and socially constructed in American society. The social construction of juvenile delinquency started far earlier than the first juvenile court in 1899 in the U.S. Scholars have tried traditional historical analysis to explore the timeline of the social construction of juvenile delinquency in the past, but it is inefficient to examine hundred years of documents using traditional paper-and-pencil methods. This project aims to study the social construction of juvenile delinquency in the United States using data analysis of scanned historic newspaper collections. It combines image and linguistic analyses, and big data tools to analyze hundreds of years of scanned newspaper images and show a clear development of social construction of juvenile delinquency in the American society. Currently, the startup phase analyzes data from an archive of newspapers (1853-1921) from the Library of Congress Chronicling America website (http://chroniclingamerica.loc.gov/newspapers/). Sandeep will provide a very brief overview of the project, discuss the image analysis tools being designed and developed as part of this project, specifically with regard to segmentation of newspaper articles and OCR, their current progress, and some of the upcoming tasks in the text analysis and visualization stages of the project.
