Want to help the poor? Don’t waste your time with the minimum wage
Interesting: "In Canada the link between minimum wage increases and lower employment levels is stronger than in the U.S. ... empirical studies that use Canadian data are able to exploit variations in the minimum wage both across time and across provinces (in the U.S., on the other hand, the minimum wage is largely driven by changes at the federal level)." From an earlier metaanalysis of the Canadian literature: "Overall it appears that the Canadian studies tend to find adverse employment effects that are at least as large and likely larger than US studies; certainly none find positive employment effects as occasionally occurs in the US."
Jewish Problems
"This is a special collection of problems that were given to select applicants during oral entrance exams to the math department of Moscow State University. These problems were designed to prevent Jews and other undesirables from getting a passing grade. Among problems that were used by the department to blackball unwanted candidate students, these problems are distinguished by having a simple solution that is difficult to find. Using problems with a simple solution protected the administration from extra complaints and appeals. This collection therefore has mathematical as well as historical value."
Chocolate Toothpaste could revolutionize oral care
"Doctor Tetsuo Nakamoto, the father of News 2's Chris Nakamoto, found "Theobromine" in chocolate in the early 80s. Since then, he worked to get a patent and put that substance into a toothpaste. 'Theodent is a fluoride free toothpaste,' Theodent CEO, Dr. Arman Sadeghpour said. 'Rennou, our active ingredient works better to re-mineralize the surface of human teeth.' Clinical trials show the positive effects of Rennou on a tooth."
Serena Williams blasts back at Andy Murray: I'd slam a man
So, roughly restated, the reigning women's world champion claims that, if she were to focus a lot more rigidly on her training she might be able to beat a man ranked below the top-100. Given that after she'd previously made similar remarks #203-in-the-world beat both her and her sister in a single afternoon after a not-so-rigorous warmup routine involving a round of golf and few beers this claim still seems worth contesting.
