Tocqueville's America is another project of the American Studies Programs at The University of Virginia. In this project we take up the task of re-contextualizing Alexis de Tocqueville's famous political and cultural analysis of American democracy. Our objective is, over time, to return that book -- arguably still one of the most influential works in political thought -- to its origins, to the America of 1831-32 . For it was on that very specific ground and at that very specific historical momen
Conservation and biodiversity
Dr. Richard Field research interests lie in conservation, biodiversity and the forces that structure ecological communities. In this podcast, Dr Field from the School of Geography compares and contrasts his experiences as a researcher in national parks in Honduras and Indonesia, and the different types of ecological communities he has studied, and goes on to introduce the emerging field of conservation bio-geography.
Love on the rocks?
How badly has the recession affected the relationship between political parties and business? Expert in the field - Professor Mick Moran - assesses the cracks in the relationship and how the crisis will affect it in the future. Professor Moran was at the University to open the inaugural seminar series for the Centre for British Politics.
Orchestrating cell separation in plants: What are the risks and benefits?
In this podcast, Professor Roberts from the School of Biosciences discusses his research into the mechanism responsible for regulating cell separation in plants. In particular how plants 'shed' parts of themselves such as leaves or fruit. Professor Roberts explores the potential application of his research, through prevention or encouraging of the 'shedding' process, agricultural harvests could potentially be increased or even synchronised. Professor Roberts also discusses the resistance faced

10. Che Bella Figura! (5 Minutes A Day)
Episode #10 of LearnItalianPod "5 Minutes A Day" lesson series is now live! This one is entitled "Che Bella Figura!". Italian author Beppe Severgnini in his interesting book "La Bella Figura - A Field Guide To The Italian Mind" says that only in Italian does there exist an expression like "fare bella figura". It corresponds [...]
Plasmapause Convects to the Magnetopause During Halloween Solar Storm
The plasma sphere is a region of ionospheric plasma which co-rotates with the Earth, carried by the magnetic field lines. The plasma pause marks the outer boundary of this region. This colder plasma is more easily moved by the electric fields created by strong solar storms. In the Halloween 2003 event, these fields convected some of the cold plasma out to the magnetopause (grey, semi-transparent surface) and reduced the size of the cold plasma region near the Earth. For this visualization, the 3
Topological Features of a Compressible Plasma Vortex Sheet - a Model of the Outer Heliospheric Wind
The Voyager and Pioneer Spacecraft have detected large-scale quasi-periodic plasma fluctuations in the outer heliosphere beyond 20 AU. A plasma vortex sheet model can explain these fluctuations and the observed correlations between various physical variables. The large scale outer heliosphere is modeled by solving the 3-D compressible magneto-hydrodynamic equations involving three interacting shear layers. Computations were done on a Cray computer at the NASA Center for Computational Sciences. S
Gaps in the Earths Radiation Belts
The Earth's radiation belts (violet & white) change considerably due to a number of influences, ranging from a changing solar wind to the lightning on the Earth. Here we see a range of variation in the electron flux in early December 2003. White indicates higher electron flux than violet. The gray curves represent the lines of the Earth's magnetic field. These radiation belts are constructed on a per-orbit basis with data from SAMPEX.
VIS-5D VR Animations: R-Aquarii Jet
The VIS-5D scientific visualization system has been extended to include an interactive mode controlled by virtual environment devices. This animation is part of a series of live screen captures demonstrating this capability.
Kepler Mission Star Field Lithograph
This two-sided 8in. X 10in. print document depicts the Kepler Mission Field of View imposed upon a star field that includes the constellations Cygnus and Delphinus on the front. A description of the mission, the star selection constraints, the location of the field in the night sky, distances to the stars, and the CCD layout is included on the back. An image on the back also illustrates the distance the field is from the galactic center and the size of the field of view. NASA-s Kepler mission is
Oceanic Intraplate Volcanism
This PowerPoint presentation is part of the Whitman College petrology course. This 29-slide presentation covers the compositional evolution of basalt using high field strength, large-ion lithophile, rare earth elements, and isotope geochemistry. Mantle reservoirs (depleted mantle, bulk silicate earth, enriched mantle, prevalent mantle, High mu mantle) are discussed and illustrated. This resource is part of the Teaching Petrology collection. http://serc.carleton.edu/NAGTWorkshops/petrology03/inde
"From Molecules to Behavior: Synaptic Neurophysiology, Spring 2010"
"Like transistors in a computer, synapses perform complex computations and connect the brain's non-linear processing elements (neurons) into a functional circuit. Understanding the role of synapses in neuronal computation is essential to understanding how the brain works. In this course students will be introduced to cutting-edge research in the field of synaptic neurophysiology. The course will cover such topics as synapse formation, synaptic function, synaptic plasticity, the roles of synapses
"Introduction to Women's and Gender Studies, Spring 2009"
"This course is designed as an introduction to the interdisciplinary field of Women's and Gender Studies, an academic area of study focused on the ways that sex and gender manifest themselves in social, cultural, and political contexts. The primary goal of this course is to familiarize students with key issues, questions and debates in Women's Studies scholarship, both historical and contemporary. This semester you will become acquainted with many of the critical questions and concepts feminist
