Homogenization and Field Concentrations in Heterogeneous Media

A multi-scale characterization of the field concentrations inside composite and polycrystalline media is developed. We focus on gradient fields associated with the intensive quantities given by the temperature and the electric potential. In the linear regime these quantities are modeled by the solution of a second order elliptic partial differential equation with oscillatory coefficients. The c...

Market Structure and Media Diversity 1

We estimate the demand for local news service described by the offerings from newspapers, radio, television, the Internet, and Smartphone. The results show that the representative consumer values diversity in the reporting of news, more coverage of multicultural issues, and more information on community news.
