...1960s, but newfangled, bright--and still relatively expensive--concrete that has come on to the market this decade. High-performance concrete (or ultra-high-performance, as it's known in the industry) is up to 10 times as strong as regular concrete. It costs several times as much as standard concrete, yet industry experts say price comparisons are misleading because the high-tech versions have properties that make them more comparable to materials such as stainless steel and aluminum, which can be even pricier. Those attributes give architects, engineers and builders far greater flexibility to use concrete's long-lasting...
...their most recent paper, published in the British Medical Journal, Christakis and Fowler explored the emotional state of nearly 5,000 people and the more than 50,000 social ties they shared. At three points during the long study, all the participants answered a standard questionnaire to determine their happiness level, so that the scientists could track changes in emotional state. That led to their intriguing finding of just how contagious happiness can be: if a subject's friend was happy, that subject was 15% more likely to be happy too; if that friend's friend was happy, the original...
...fact that Washington teachers didn't even want to choose between merit pay, based on performance, plus losing a year of tenure, and a standard smaller raise on an annual basis exposes the core issue regarding our failed public-school system. The vast majority of public-school teachers (as represented by their union) are willing to accept below-proficiency pay in return for job security because they are painfully aware of their collective ineptitude. When tenure is eliminated and teachers can make up to $130,000 per year for extraordinary performance, educators like me may be encouraged to (re)join...
...pipe, empty canned food containers, and shopping cart parts. In other words, this show bestows upon you an amazingly overactive utilitarian mentality. Also, avant-garde—that is all. 1. “The Amazing Race” Geography and stereotypes—one is dangerously ignored in standard education curricula, and the other is a little too reinforced on the show. One day I hope to be one-half of Happy Couple. (Also, never, ever be the only team on an airplane flight. Ever.) —Denise J. Xu is an incoming Campus Arts Editor. She?...
...mission was also historically implausible: Afghanistan has never had a strong central government. It has been governed for thousands of years by local and regional tribal coalitions. The tribes have often been at one another's throats - a good part of the current "Taliban" uprising is nothing more than standard tribal rivalries juiced by Western arms and opium profits - except when foreigners have invaded the area, in which case the Afghans have united and slowly humiliated conquerors from Alexander the Great to the Soviets...
