1. In endangered wooded pasture ecosystems established tree saplings are frequently found in spatial association with protective structures, suggesting nurse effects. This associational resistance is thought to be a driving force behind tree regeneration in wooded pastures. Experimental evidence for associational resistance is, however, scarce. We studied the effects of unpalatable plants on tr...

Abstract In this paper we develop a new composite indicator, named Social Catalyst , able to account for the complex and multifaceted nature of social capital in unitary measure. We use our as well its components, explore relation between electoral participation parliamentary elections Italy from 1994 2008, addressing potential endogeneity bias. Our findings show that (i) positively significant...

Concern over the distributional effects of policies which induce changes in peer group structure, or ‘associational redistributions’ (Durlauf, 1996c), motivates a substantial body of theoretical and empirical research in economics, sociology, psychology, and education. A growing collection of econometric methods for characterizing the effects of such policies are now available. This chapter sur...

Recent studies have shown that neurons in the visual cortex responding to related features tend to synchronize their activity. Although synchronous oscillations have been observed in associational cortices during visual working memory activity, there has been few modeling attempts to address the process which could simultaneously generate both types of dynamics. We propose a realistic mechanism...

Illusions of inappriopriate familiarity with the current experience or hallucinatory recall of memories have been reported in temporal lobe epilepsies. Pathophysiological hypotheses have been put forward, involving either the limbic regions of the temporal lobe (Jackson), the temporal neocortex ("interpretive cortex", Penfield), or both (Bancaud). New data, acquired in the course of presurgical...
