Cooperation, Norms and Conflict: Towards Simulating the Foundations of Society
In order to understand social systems, it is essential to identify the circumstances under which individuals spontaneously start cooperating or developing shared behaviors, norms, and culture. In this connection, it is important to study the role of social mechanisms such as repeated interactions, group selection, network formation, costly punishment and group pressure, and how they allow us to transform social dilemmas into interactive situations that promote the social system. Furthermore, it
Emil Kraepelin and the origins of modern psychiatry
One hundred years ago, Emil Kraepelin (1856-1926) was the most influential psychiatrist in the world, revered as the man whose system of classification put the study of mental illness on firm scientific foundations. We owe to Kraepelin the distinction... (Running Time 61:57)
Anatomy of a meltdown The GFC Forum: Cause, effect and recovery
Few public events are significant enough to justify their own acronym. In even fewer instances are those acronyms readily understood worldwide. Clearly the global financial crisis, or GFC, is one such event. Much has been said and done about it already. But how accurate or effective has this been? Are fingers being fairly pointed? Can the cracks be repaired, or do we need a whole new system?
3.3.2 Benzene, toluene and xylene In addition to benzene itself, the catalytic reformer also produces ethylbenzene, toluene and the isomeric xylenes directly. The demand for ethylbenzene is always great as a source of styrene monomer, but toluene does not find great use apart from a relatively small application in polyurethane. This is why most toluene is de-alkylated to increase overall benzene production. A similar problem exists with the xylenes:

The Jepson Leadership Forum presents Moisés Kaufman
Tony- and Emmy-nominated director Moisés Kaufman discussed how art plays a leadership role in society in his lecture "Toward a New Theater" at the Jepson Leadership Forum. Kaufman is known for his work on The Laramie Project, the University of Richmond's One Book, One Richmond 2013-14 selection. His visit was part of the Jepson Leadership Forum, the One Book, One Richmond program, and the WILL/WGSS Speaker Series. It was cosponsored by Common Ground and Theatre & Dance. Feb. 24, 2014
Students examine images of galaxies and learn to recognize the various shapes used in the Hubble classification system. They can follow the site independently, using a worksheet that prompts them to answer questions in the text, then take a java "quiz" that requires them to place various galaxies in their correct positions on the Hubble "tuning fork." There is some supplemental material about galaxies and Hubble's observations.
Pollen Bots Activity
This activity visits the Japanese Weather Site that uses pollen monitoring robots as part of a remote sensing system in Japan. The robots collect current pollen counts in Japan.
Remembering Jim Crow
Remembering Jim Crow is a companion to a radio documentary, and examines the system that, for much of the 20th century, barred many African Americans from their rights as U.S. citizens. Read personal histories of segregation. See a sampling of Jim Crow laws. Learn how African Americans fought economic hardships imposed by Jim Crow and how they built social institutions to combat segregation.
Joan Casanovas: The apprenticeship system in Cuba 1839-1870s
Joan Casanovas of the Univ. Rovira i Virgili, Tarragona, gives this public lecture entitled 'The apprenticeship system in Cuba 1839-1870s' at The Australian National University.
Neuroscience for Kids
This site explores the brain and nervous system. Learn about brain development, brain lobes, the cerebral cortex, the skull, blood supply, brain fitness, neurons, the autonomic nervous system, sensory systems, the spinal cord, laughter and the brain, the musical brain, face recognition, drug effects, neurological and mental disorders, and more.
Water management in Urban Areas
Master course on design and planning of the urban water management system. It deals with fluxes and processes in water and soil. Furthermore, aspects of water management policy development are discussed.
Advanced semiconductor devices are a new source of energy for the 21st century, delivering electricity directly from sunlight. Suitable semiconductor materials, device physics, and fabrication technologies for solar cells are presented in this course. The guidelines for design of a complete solar cell system for household application are explained. Cost aspects, market development, and the application areas of solar cells are presented.
This resource consists of a Java applet and expository text. The applet is a simulation of the fire process, an interacting particle system consisting of a rectangular lattice of "trees". At each discrete time unit, each tree is either on green, on fire, or burnt. A tree on fire at a given time can catch neighboring trees on fire at the next time unit. The probabilities of fire spread can be varied.
Tsunamis harbor an element of surprise: In the deep ocean, tsunami waves pass unnoticed beneath boats, yet they rise to dangerous heights near shore. How do tsunamis work? What was the worst tsunami in recorded history? How does a tsunami warning system work?

The Power of Revolutionary Thinking: What Today's Scientists Can Teach You About Driving Innovat
“You’ll be on your way up!
You’ll be seeing great sights!
You’ll join the high fliers who soar to high heights.”
While Dr. Seuss may not have been a direct inspiration, “Oh, the Places You’ll Go!” seems especially suited to these four “brainy and footsy people” with exceptional re
Worldwide Amphibian Declines
AmphibiaWeb is an online system enabling anyone with a Web browser to search and retrieve information relating to amphibian biology and conservation. This site was inspired by the global declines of amphibians, the study of which has been hindered by the lack of multidisplinary studies and a lack of coordination in monitoring, in field studies, and in lab studies. We hope AmphibiaWeb will encourage a shared vision for the study of global amphibian declines and the conservation of remaining amphi
This is a project to develop a document for teaching graduate econometrics that is "open source", specifically, licensed as GNU GPL. That is, anyone can access the document in editable form, and can modify it, as long as they make their modifications available. This allows for personalization, as well as a simple way to make contributions and error corrections. The hope is that people preparing to teach econometrics for the first time might find it useful, and eventually be motivated to contribu
