According to recent proposals in formal syntax, the left-most position in the C(omplementizer)-layer is dedicated to the representation of the context of utterance (call this hypothesis LP). This idea has had little impact on semantic theories of indexicals. The reason is that indexicals are regarded, after Kaplan’s (1989) Logic of Demonstratives (LD), as directly referential and rigid. However...

In this paper we investigate the core-periphery structure of the Italian interbank market. We construct quarterly networks from a dataset containing all overnight interbank transactions on the e-MID trading platform from January 1999 to December 2010. In order to shed light on the hierarchical structure of the banking network, we estimate different versions of a core-periphery model. Our main n...

 In this study, high-carbon, chromium alloy steel (100Cr6) having the initial spheroidized microstructure was welded using the rotary friction welding method. The effects of process parameters such as friction time and friction force were experimentally investigated. The friction welded joints were produced of two 100Cr6 steel rods. In order to examine the microstructure and mechanical properti...

We study a model of network formation where the bene…ts from connections exhibit decreasing returns and decay with network distance. We show that the unique equilibrium network is a periphery-sponsored star, where one player, the center, maintains no links and earns a high payo¤, while all other players maintain a single link to the center and earn lower payo¤s. Both the star architecture and p...

Yeast mother cells pay a sacrifice during budding: they keep the extrachromosomal rDNA circles (ERCs) so that their buds have a full lifespan ahead. Two new studies indicate that retention of ERCs in mother cells occurs not by tethering to the nuclear periphery but rather by the simple rules of diffusion in a time-limited and complex landscape.

The most salient feature of the spatial economy is the presence of a large variety of economic agglomerations. Our purpose is to review some of the main explanations of this universal phenomenon, as they are proposed in urban economics and modern economic geography. Because of space constraints, we restrict ourselves to the most recent contributions, referring the reader to our forthcoming book...
