Great news browser and filter, but very limited network visualizations

SNA package used for "ordinary" data (one line of data for each case) and for network data (two files - "nodes" and "links" )

Big data might very well be the tech buzz word of the year. And just how hot is it? Consider this:  Data scientist Stephen Purpura - an expert in artificial intelligence, machine learning and predictive analytics who is studying for his PhD in information sciences at Cornell University - has received no fewer than 45 job offers in recent months. And they just aren't any fly-by-night offers, with some rolling in from big-name companies touting salaries of $300,000 or more.

Rioting and related intra-crowd dynamics are significant human processes, but we know less about the basic behavioral science and subsequent processes that drive and shape rioting than we would like to. This is due, in large part, to the difficulty in studying riots on the ground and to the sheer complexity of riot phenomena. We know even less about the geographical dynamics of rioting, even though there is a dedicated (but only general) appreciation that geography is important. Existing work has, for the most part, adopted the most straightforward path to discovery, by examining coarse (city-scale) geographies of rioting, or in the few instances where intra-crowd riot dynamics are considered they have focused on stylized abstractions of behavior. Because of the difficulties of using standard social science inquiry to study riots (surveys, ethnographic analysis, interviews), many researchers have turned to computer modeling to create synthetic riots that can be configured, sampled, and experimented with. But, building models of something as bewilderingly complex as rioting is really quite difficult and so many short-cuts are taken. In particular, models are usually cellular-based in form (where rasters represent people and their local environment) and founded on physical interactions between relatively "dumb" particle-people (where continuum mechanics, random walks, or particle-particle forces serve as a substitute for socio-spatial interaction and behavior).

Five of the nation's largest banks were required to pay states a total of $2.5 billion as part of this year's mortgage settlement. The money was intended to alleviate the foreclosure crisis, but many states aren't exactly using the funds that way. We made a map of what each state is doing with the millions of dollars it received.
