As home to the Innovative Prosecution Solutions (IPS) Research and Evaluation Training and Technical Assistance team, RTI International has developed a webinar series to support the creation and ongoing engagement of a learning community of local researchers and practitioners interested in discussing evaluation-related topics, sharing methodological techniques, and addressing problem-solving challenges in carrying out applied research. In the fourth webinar in the series, research partners from two IPS Projects discuss how they are utilizing — or plan on utilizing – social network analysis (SNA) to aid in action research. View the discussion to learn more about the basics of SNA and how it can be used to better understand the relationships between opioid manufacturers, distributors, and overdose victims.
