This article moves the debate on the integrative mechanisms of civil society from the study of individual civic engagement and associational life to the study of interorganizational civic networks. Drawing upon evidence from Bristol and Glasgow, we identify a polycentric model of civic networks, based on horizontal solidarity and generalized reciprocity, in(More)
It is difficult to grasp the nature of social movements. 1 They cannot be reduced to specific insurrections or revolts, but rather resemble strings of more or less connected events, scattered across time and space; nor can they be identified with any specific organization, rather, they consist of groups and organizations, with various levels of(More)
This article accounts for two puzzling paradoxes. The first paradox is the simultaneous absence and presence of attitude polarization, the fact that global attitude polarization is relatively rare, even though pundits describe it as common. The second paradox is the simultaneous presence and absence of social polarization, the fact that while individuals(More)
This paper deals with the problem of retrieving optically active parameters of the water from multispectral remotely sensed data. We analyse the neural networks approach applied to the estimation of chlorophyll concentration in coastal waters (Case II Waters) and discuss the use of two types of networks: the Radial Basis Function neural network and(More)
Does fiscal consolidation lead to social unrest? Using cross-country evidence for the period 1919 to 2008, we examine the extent to which societies become unstable after budget cuts. The results show a clear correlation between fiscal retrenchment and instability. Expenditure cuts are particularly potent in fueling protests; tax rises have only small and(More)
In this paper a new algorithm for striping noise reduction in hyperspectral images is proposed. Signal dependent striping noise is reduced by exploiting the high degree of spectral correlation of the useful signal in hyperspectral data. The algorithm does not require the human intervention nor introduces significant radiometric distortions on the useful(More)
This paper proposes a preliminary conceptual approach for studying how social media (i.e., a class of specific Internetbased communication tools) can be strategically employed to promote social innovation (i.e., the actual consolidation of norms guiding democratic and participated policymaking processes). To this aim, we propose to overcome monolithic(More)
