In a symmetric information voting model, an individual (information controller) can influence voters’ choices by designing the information content of a public signal. We characterize the controller’s optimal signal. With a non-unanimous voting rule, she exploits voters’ heterogeneity by designing a signal with realizations targeting di↵erent winning-coalitions. Consequently, under simple-majori...

We evaluate the matrix elements 〈r〉 for the n-dimensional harmonic oscillator in terms of the dual Hahn polynomials and derive the corresponding three-term recurrence relation and the Pasternack-type reflection relation. A short review of similar results is also given. 1. An Introduction The purpose of this note is to present a simple evaluation of the expectation values 〈r〉 for the n-dimension...

Time is an important dimension of any information space. It can be very useful for a wide range of information retrieval tasks such as document exploration, similarity search, summarization, and clustering. Traditionally, information retrieval applications do not take full advantage of all the temporal information embedded in documents to provide alternative search features and user experience....

Presented with the opportunity to trade, countries bene t by specializing in the activities they do relatively better. This nding, the principle of comparative advantage, is one of the rst analytic results in economics. While Adam Smith (1776) made a much earlier case for free trade, he based it on increasing returns to scale, and provided no formal demonstration. In contrast, David Ricardo (...
The XML Fragment model offers a convenient formalism for querying XML collections "by example", that is, by formulating the query as a piece of XML that expresses the user's needs. This allows relevant results to be returned either as full documents or as XML Fragments, using a simple extension of the vector space model for ranking. In this work, we investigate extending this model to text anal...
