Social Network Analysis

Transcription

1 Bocconi University Ph.D. School Social Network Analysis Doctoral Seminar Fall 2015 Instructor : Prof. Giuseppe (Beppe) Soda Office Hours: giuseppe.soda@unibocconi.it Overview Organizational social network research has achieved a prominent position in management and social sciences as evidenced by the network theme of the Academy of Management meetings in Denver in 2002, by special issues appearing in our major journals, and by the sheer volume of work that uses network ideas and network methods. Network studies have appeared regularly in management journals, contributing to the investigation of a wide range of organizational topics across different levels of analysis. The following figure illustrates the exponential growth of network research since his origin in the fields of socio-psychology and anthropology. 1

2 The objective of this course is to familiarize students with the theory, research and methodological issues connected with social network analysis in organizational contexts. Upon completion of the course, students should have a good grasp of social network concepts and methods, and be able to use them to conduct research. A tutorial prepared by the instructor in three main sections will be circulated to support both your conceptual and methodological learing. Please come to class prepared to discuss the readings for that day. Where appropriate, we have assigned data and theory exercises to illustrate specific topics. Your completion of these exercises is an important aspect of the class, and will help familiarize you with the UCINET software that includes the standard tools used in organizational network analysis. Please, download on your PC the latest version of UCINET VI ( Course Evaluation Class contribution (class discussion, and, of course, attendance and punctuality): 40% Final paper: 60% Students are required to do a short paper that should involve the exploration, from a social network perspective, of a theory-driven question of interest to management scholars. Here are some options to consider. a) A critical literature review. This should be focused on some specific aspects of organizational social network research. Be sure to specify the boundaries of your review with respect to level of analysis and substantive domain. b) A theory development. Instead of reviewing literature, you could try to propose a new theoretical direction and specify a research agenda. c) A empirical research. Using a data-set you can try to test some hypothesis addressing Network issues.

3 Instructor: Giuseppe Beppe Soda: PhD in Management, Bocconi University, Professor of Organization Theory at Bocconi University, and Head of Department of Management & Technology ( He has been a visiting professor at the Heinz III School, Carnegie Mellon University, Pittsburg (PA, USA), , at Carlson School of Management, University of Minnesota (2005, 2006 and 2007), and at IE Business School Madrid (2010). In his research and teaching activity has been awarded for: Excellence in Research Award, Bocconi University 2013, 2012, 2009, 2008 and 2001; Excellence in Teaching Award for undergraduate courses, Bocconi University ( ); Best Paper Award, Bocconi School of Management (2005), MBA Teacher of the Year, SDA Bocconi School of Management (2005); Master Teacher of the Year, SDA Bocconi School of Management (2004); Case Study of the Year His research interests are broadly concerned with understanding how organizational networks and inter-firm collaborations making influence on organizational level outcome, where do networks come from, how they evolve over time, and impact of time on the relationships between network structures and outcome. He has also investigated how network analysis can be used to design effective organizations and firm governance. Broadly, themes that he has been researching include: Antecedents, mechanisms and forms of Interfirm networks; the performance implications of inter-organizational networks; the impact of time on the relationships between network structures and outcome; the genesis and dynamics of network structures; network approach to organizational and governance design; co-evolution of meanings and network structures within organizational teams.
