Reframing Ethnographic Film

Book description: From a boom in theatrical features to footage posted on websites such as YouTube and Google Video, the early years of the 21st century have witnessed significant changes in the technological, commercial, aesthetic, political, and social dimensions of documentaries on film, television and the web. In response to these rapid developments, this book rethinks the notion of documentary, in terms of theory, practice and object/s of study. Drawing together 26 original essays from scholars and practitioners, it critically assesses ideas and constructions of documentary and, where necessary, proposes new tools and arguments with which to examine this complex and shifting terrain. Covering a range of media output, the book is divided into four sections: * Critical perspectives on documentary forms and concepts * The changing faces of documentary production * Contemporary documentary: borders, neighbours and disputed territories Digital and online documentaries: opportunities and limitations

Magnus Force in High Temperature Superconductivity and Berry Phase

In the topological framework of high temperature superconductivity we have discussed the Magnus force acting on its vortices

Asymmetric Simple Exclusion Process on a Cayley Tree

We study the asymmetric exclusion process on a regular Cayley tree with arbitrary co-ordination number. In this model particles can enter the system only at the parent site and exit from one of the sites at the last level. In the bulk they move from the occupied sites to one of their unoccupied downward neighbours, chosen randomly. We show that the steady state current that flow from one level to the next is independent of the exit rate, and increase monotonically with the entry rate and the co-ordination number. Unlike TASEP, the model has only one phase and the density profile show no boundary layers. We argue that in blood, air or water circulations systems branching is essential to maintain a free flow within the system which is independent of exit rates.Comment: 8 pages, 3 eps figure
