We develop a model of voluntary gradual franchise extension and growth based on the idea that voting is an information aggregation mechanism. A larger number of voters mean that more correct decisions are made hence increasing output, but also imply that any incremental output must be shared among more individuals. These conflicting incentives lead to a dynamic model of franchise extensions tha...

number of clusters. This was based on the final clustering In this paper we extend an earlier result within DempsterShafer theory [“Fast Dempster-Shafer Clustering Using a Neural Network Structure,” in Proc. Seventh Int. Conf. Information Processing and Management of Uncertainty in Knowledge-Based Systems (IPMU’98)] where several pieces of evidence were clustered into a fixed number of clusters...

The boundary identification represents an interesting and difficult problem in image processing, mainly if two flat zones are separated by a gradual transition. The most common edge detection operators work properly for sharp edges, but can considerably fail for gradual transitions. In this work, we propose a method to eliminate gradual transitions which preserves the number of the image flat z...

What is the impact of surprise and anticipated policy changes when agents form expectations using adaptive learning rather than rational expectations? We examine this issue using the standard stochastic real business cycle model with lump-sum taxes. Agents combine knowledge about future policy with econometric forecasts of future wages and interest rates. Both permanent and temporary policy cha...

This paper shows that in online auctions like eBay, if bidders can only place bids at random times, then many different equilibria arise besides truthful bidding, despite the option to leave proxy bids. These equilibria can involve gradual bidding, periods of inactivity, and waiting to start bidding towards the end of the auction bidding behaviors common on eBay. Bidders in such equilibria impl...

In this paper a set of de nitions describing general real number representation sys tems is presented Our purpose is to nd a su ciently wide model de nition including classical systems signed digit notation linear numeration systems p adic numbers symmetric level index arithmetic but speci c enough to make it possible to build some practical results We focuse on the redundancy property and the ...

da is a memory of iraqi war against iran. this narration of war is a representation of young girl life that had a significant role in her own time. this book challenges masculinity of war and passes out gender as a limitation. the important narration of war, mentioned in da, has been associated with 150 republication and these elements confirm research on da. this article tries to attempts to a...

The forced swim test (FST) is a pre-clinical test to short and long term treatment with antidepressant drugs (ADT), which requires between-subject designs. Herein a modified protocol of the FST using within-subject design (repeated rat-FST) was evaluated. Male Wistar rats were submitted to 15 min of swimming (Day 1: pretest) followed by three subsequent 5 min-swimming tests one week apart (Day ...
