Class 31: GIUSEPPE SODA

This course provides an intensive introduction to the field of social network analysis. The course is divided in class-lecture sessions and lab-exercise sessions. The objective is to familiarize students with the theory, research, methodological issues, and practical implications connected with social network analysis. Upon completion of the course, students should have a good grasp of social network concepts and methods, and be able to use them. The course covers theory, concept and method as well as hands-on application in the lab-sessions. The purpose of the lab-sessions is to teach how to analyze social network data. This means mastering the software tools as well as analytical strategies. Students need to bring their own laptop to effectively participate in the lab. Network concepts covered include graph-theoretic fundamentals, centrality, cohesion, subgroups, equivalence. Theoretical areas include embeddedness, social capital, organizational learning and organizational governance. This perspective is integrated with a practitioner perspective by using examples from consulting engagements.

Fluent in English.
The teaching method requires the use of personal computers for the lab-sessions. The completion of exercises is an important aspect of the class, and help to familiarize with the UCINET software that includes the standard tools used in organizational network analysis.
All students are required to download on their PC the latest version of UCINET (www.analytictech.com).
