...second study in the same journal, researchers at Iowa State University used computer modeling to figure out how the length of a runner's stride might change the force applied to his or her bones and thereby affect the risk of stress fractures. Researchers recruited 10 male participants, each of whom typically ran about three miles per day, and calculated their risk of experiencing a stress fracture - about 9% over 100 days. By observing the participants running at varying stride lengths and recording the amount of force their foot strikes exerted on the ground, researchers were able to estimate...
...reason is less air time, researchers say - the less time a runner's feet spend airborne, the less force they strike the ground with. Still, the results of a mathematical model are difficult to re-create in real life, especially since it takes a fair amount of practice to adjust to a shortened stride. Runners who abbreviate their stride try instinctively to quicken their pace to compensate. That can negate any protective effect of stride shortening - when you speed up, the force on the bone increases proportionately...
...after the initial research is done. Without that, excavations are being started and then left open when local funding dries up, Khan says. "We don't have the resources to protect each and every site in Gandhara," he explains. "We don't have any resources to make it a model site for tourism, which would create jobs and bring in money...
...Witherell stresses that the union aims to implement the basic principles of worker ownership and democratic governance rather than precisely replicate the Mondragon model. Still, he says, success comes down to well-run companies that meet a need. "The people who formed these co-ops did not do so because of some egalitarian ideal - they did it out of the necessity to feed and provide for their families...
...Arizmendi now employs 125 workers and annually generates $12 million in sales. Despite the economic downturn, the businesses remain strong and poised for growth. This in part owes to the collective decision-making model, says Hoover. "Worker-owned cooperatives are an innately conservative form. We didn't overleverage ourselves...
