Panel 4: Economic Impacts of HSR: Lessons for California
Other countries have decades of experience living with HSR and observing how it has influenced their urban economies. While HSR has broad, and often difficult to quantify, economic impacts, experiences from the Europe and Japan suggest that HSR can increase productivity and competitiveness by reducing the "time/space relationship" between cities. This panel will explore the economic impacts of HSR projects abroad and offer timely lessons for California to maximize the economic benefits of HSR fo

Catching Solar Waves
Kelvin-Helmholtz instabilities occur when two fluids of different densities or different speeds flow by each other. In the case of ocean waves, that's the dense water and the lighter air. As they flow past each other, slight ripples can be quickly amplified into the giant waves loved by surfers. In the case of the solar atmosphere, which is made of a very hot and electrically charged gas called plasma, the two flows come from an expanse of plasma erupting off the sun's surface as it passes by pl

"The Momentum Was Catching On:" Lillian Roberts Describes Organizing Hospital Workers in New York Ci
Municipal workers led a wave of strikes that made the 1960's and early 1970's a highpoint for organized labor militancy in New York City. Teachers, social workers, sanitation workers, and parks employees all fought to improve work conditions, low-paying wage scales, and to reform the city's social services. Lillian Roberts arrived in New York in 1965 to organize low-paid and often disrespected hospital workers for American Federation of State, County, and Municipal Employees (AFSCME). At the tim

Chlorine Nitrate over the Arctic from CLAES (2-12-93 - 3-16-93)
Key to understanding the chlorine chemistry in the polar stratosphere is the measurement of polar stratospheric clouds, chlorine monoxide, and the reservoir gas chlorine nitrate. Chlorine nitrate has been measured by the Cryogen Limb Array Etalon Spectrometer, CLAES. CLAES makes measurements by looking at infrared emission from cloud particles and trace gases. CLAES measurements help to show that the polar stratospheric clouds which form in the cold Arctic stratosphere have converted most of the

Introducción a la Economía de la Empresa (2011)
Esta asignatura constituye la primera toma de contacto del alumno con el mundo de la empresa, lo que condiciona los objetivos didácticos de la misma. Ello requiere integrar en un mismo curso materiales pedagógicos descriptivos y analíticos, procurando no caer en un exceso de abstracción y formalismo que distancie al alumno de la realidad, o por el contrario, en un exceso de descripción que carezca de capacidad interpretativa. En definitiva, se plantea la necesidad de facilitar la descripci
