Eclipsing Binaries in Open Clusters

Detached eclipsing binaries are very useful objects for calibrating theoretical stellar models and checking their predictions. Detached eclipsing binaries in open clusters are particularly important because of the additional constraints on their age and chemical composition from their membership of the cluster. I compile a list containing absolute parameters of well-studied eclipsing binaries in open clusters, and present new observational data on the B-type systems V1481 Cyg and V2263 Cyg which are members of the young open cluster NGC 7128.Comment: 4 pages, 2 colour figures.

Building on Weber to understand governance: exploring the links between identity, democracy and 'inner distance'

The paper builds up a conceptual picture of two types of governance - network and organic. In this process it highlights the legitimacies of co-ordination (interior authority and democracy) that lie outside Weber's typology of domination and are relatively neglected in governance literature. The exploration of interior authority, through discussion of identity and substantive liberty, reflects a perspective on human agency that acknowledges the interconnection of the social and non-social and links sociological understanding of agency with political philosophy. It is suggested that this theoretical work gives some necessary content to Weber's concept of inner distance. In turn, this also has implications for our understanding of what is involved in democratizing governance
