Social mechanisms and strategic action fields: The example of the emergence of the European Research Area
2017
The point of departure of this article is Fligstein and McAdam’s A Theory of Fields. It is argued that their theoretical framework would be strengthened by a more systematic focus in social mechanism-based explanations since this would increase understanding of how new strategic action fields (SAFs) emerge. This argument is illustrated by exploring the emergence of the European Research Area (ERA) as a SAF. In identifying social mechanisms the article draws both on Fligstein and McAdam’s studies and on academic capitalism literature. The main conclusion is that the emergence of the ERA was brought about by multiple social mechanisms such as collective attribution of threat/opportunity, soc…
(K)over-bar* mesons in dense matter
2010
We study the properties of (K) over bar* mesons in nuclear matter using a unitary approach in coupled channels within the framework of the local hidden gauge formalism and incorporating the (K) over bar pi decay channel in matter. The in-medium (K) over bar *N interaction accounts for Pauli blocking effects and incorporates the (K) over bar* self-energy in a self-consistent manner. We also obtain the (K) over bar* (off-shell) spectral function and analyze its behavior at finite density and momentum. At a normal nuclear matter density, the (K) over bar* meson feels a moderately attractive potential, while the (K) over bar* width becomes five times larger than in free space. We estimate the t…
