Learning Hierarchical Workflows Using Community Detection

Workflows identified from user event logs and click-stream data are useful as knowledge bases for behavioral analysis and recommendation systems. In this study we identify abstractions or summaries of event logs modeled as user activity flow networks. The abstractions are identified based on structural properties as well as user activity flow dynamics over the network using community detection methods. We apply a fast modularity optimization and multi-level resolution approach to detect hierarchical community structure in user activity flow networks. The detected communities are compared to those detected by the information-theoretic map equation minimization approach to weigh pros and cons of the fast modularity optimization approach in the workflows context. We further attempt to identify the most probable sources and sinks of user activity in individual communities and trim the network accordingly to reduce entropy of the workflow abstractions.

Translational Bioinformatics Approaches to Evaluate
and Implement Genomic Medicine Programs

There is a growing evidence base to support the use of many genomic applications in healthcare. There are, however, several barriers to healthcare providers making use of genomic data and information on a routine basis. In this talk, I will describe some of our challenges and successes with implementing genomic medicine programs within the Program for Personalized and Genomic Medicine at UMB, introduce one way to conceptualize translational research and translational bioinformatics in this context, describe a proposed model for evaluating and implementing genomic medicine programs, and describe some of my current and planned research in translational bioinformatics.

Casey L. Overby is an Assistant Professor of Medicine in the Program for Personalized and Genomic Medicine and the Center for Health-related Informatics and Bio-Imaging at the University of Maryland School of Medicine. She received her Masters of Biotechnology from the University of Pennsylvania in 2006, her PhD in Biomedical and Health Informatics and a Graduate Certificate in Public Health Genetics from the University of Washington in 2011. In 2013, she completed her post-doctoral training in the Department of Biomedical Informatics at Columbia University and started her position at University of Maryland, Baltimore.

Steve Storck (Doctoral Student) and Chris Paymon (Masters Student) from the MicroMaterials Characterization Lab, directed by Professor Marc Zupan, UMBC Department of Mechanical Engineering, won their divisions in the annual Baltimore/Washington Society for the Advancement of Materials and Process Engineering (SAMPE) student research night.  The event was held on February 26, 2014 at UM College Park this year, and brings student researchers from UMBC, University of Maryland College Park, University of Delaware and University of West Virginia together annually to showcase their research and for friendly competition judged by academics and engineering professionals. 

For the 2014 event both UMBC students won their divisions: Steve Storck participating in the oral presentation with his talk ‘Multi-Length Scale Characterization of Additively Manufactured Hybrid Nickel-Copper-Fused Deposition Model Sandwich Cores’ and Chris Paymon in the poster presentation with his submission ‘Local Mechanical Behavior Measurements of Friction Stir Welded Titanium’. 

These achievements came with an award, as well.  Steve and Chris will both go, expenses paid, to the national competition, where further success would move them on to the international competition hosted by SAMPE Europe.

April is Sexual Assault Awareness Month and there are many controversial topics that come from the discussion of sexual assault. This includes sexual assault being gender blind, hypermasculinity and victim blaming.  The article below discusses cultural differences as an explanation for why, what Americans consider to be obviously unacceptable, some may consider to be dismissible.
