Ten Simple Rules for Getting Published
The student council (http://www.iscbsc.org/) of the International Society for Computational Biology asked me to present my thoughts on getting published in the field of computational biology at the Intelligent Systems in Molecular Biology conference held in Detroit in late June of 2005. Close to 200 bright young souls (and a few not so young) crammed into a small room for what proved to be a wonderful interchange among a group of whom approximately one-half had yet to publish their first paper.

Nutrition, Inequality and Agriculture: Contested Models of Degenerative Disease in Chiapas, Mexico
The industrial agro-food system has had two significant impacts on world public health: deteriorating human and animal nutrition due to poor food quality and the emergence of new infectious diseases arising from industrial animal production facilities and centralized food processing facilities. This situation is widely misrepresented in media coverage of public health issues. The corporate food system promotes the consumption of high levels of animal protein and processed foods

"No Other Work Available for Me and My People": A Comanche Indian Migrant Farmworker Testifies befor
In the early 20th century, large-scale commercial agriculture displaced family farms, tenant farmers, and sharecroppers. Hand labor, however, remained more cost effective for harvesting certain fruits and vegetables. Farmworkers under this new system were hired only for seasonal work and had to travel frequently. The migratory experience left these workers--primarily Mexicans, Mexican Americans, African Americans, Puerto Ricans, and Filipinos├Ěpermanent outsiders and vulnerable to exploitation,

Voter Experiment
This resource consists of a Java applet and expository text. The applet is a simulation of the voter experiment, an interacting partile system that consists of a rectangular array of sites. At each discrete time unit, a site is chosen at random, a neighboring site is chosen, and the color of the first site is changed to that of the neighbor. The applet illustrates clustering of the colors and convergence to consensus.
