Elena's current research is on the diffusion of temporary organizational forms and the expertise of facilitation in the public policy field. Once the domain of government experts, regional planning in the European Union today involves many organizations negotiating future plans. These policy networks meet and act in series of projects focused on particular regions. The research investigates the interplay between these short-term actions and the future-oriented visions that they are supposed to bring about, as well as the role of the project manager or facilitator in this process

Lucas Graves is a PhD candidate in Communications at Columbia University. His dissertation, The Fact Checkers: Annotative Journalism and the New Ecology of News, studies the fact-checking movement in American journalism. The project uses participant observation, coupled with content analysis and historical research, to examine a set of emergent practices which have coalesced into a reform movement reaching to the center of the elite news media. The largest question this research tries to address is this: How has the Internet — not as a technological force, but as a complex of affordances rendered meaningful by new practices, beliefs, and organizations — transformed journalistic work and the world of news production? Lucas has worked as a technology and media analyst with various research firms and is a longtime magazine journalist, on the masthead of Wired magazine.

Aharon Cohen Mohliver
Aharon's advisor was Bruce Kogut but he worked closely with David Stark on his dissertation research. Aharon's dissertation focused on processes that make illegitimate, and often illegal practices legitimized in financial markets. His dissertation titled “Legitimized Unethicallity: the divergence of Norms and Laws in Financial Markets” is comprised of three chapters. The first examines how in Israel, and economy that is characterized by high concentration of ownership, mutual funds often invest to the detriment of their clients in highly priced IPOs if those are affiliated with their business group. This effect is not only confined to investments made within a group, the chapter shows strong evidence of reciprocity among business groups, creating systematic over-pricing of IPOs that are generated from business groups and a systematic misallocation of resources from independent IPOs to ones affiliated with a business group. His second and third dissertation chapters examine a different dataset of unethical practices and looks at the diffusion and adoption of stock option backdating among executives in the United States. These chapters show that the diffusion of backdating depends heavily on the physical and temporal distance of focal organizations from their infected peers. The papers demonstrate the concept of private legitimacy, wherein powerful legitimizing actors such as external auditors spread backdating among their clients for a decade while keeping it hidden from outsiders. Aharon is now an Assistant Professor of Strategy and Entrepreneurship at London Business School and advises the Israeli Securities Authority and various other committees.
