Scientists today are making greater efforts to study ocean currents （洋流）. Most do it using satellites and other high-tech equipment. However, ocean expert Curtis Ebbesmeyer does it in a special way — by studying movements of random floating garbage. A scientist with many years' experience, he started this type of research in the early 1990s when he heard about hundreds of athletic shoes washing up on the shores of the northwest coast of the United States. There were so many shoes that people were setting up swap meets to try and match left and right shoes to sell or wear.
Ebbesmeyer found out in his researches that the shoes — about 60,000 in total — fell into the ocean in a shipping accident. He phoned the shoe company and asked if they wanted the shoes back. As expected, the company told him that they didn't. Ebbesmeyer realized this could be a great experiment. If he learned when and where the shoes went into the water and tracked where they landed, he could learn a lot about the patterns of ocean currents.
The Pacific Northwest is one of the world's best areas for beachcombing（海滩搜寻）because winds and currents join here, and as a result, there is a group of serious beachcombers in the area. Ebbesmeyer got to know a lot of them and asked for their help in collecting information about where the shoes landed. In a year he collected reliable information on 1,600 shoes. With this data, he and a colleague were able to test and improve a computer program designed to model ocean currents, and publish the findings of their study.
As the result of his work, Ebbesmeyer has become known as the scientist to call with questions about any unusual objects found floating in the ocean. He has even started an association of beachcombers and ocean experts, with 500 subscribers from West Africa to New Zealand. They have recorded all lost objects ranging from potatoes to golf gloves.

Parents everywhere praise their kids. Jenn Berman, author of The A to Z Guide to Raising Happy and Confident Kids, says, “We've gone to the opposite extreme of a few decades ago when parents tended to be more strict.” By giving kids a lot of praise, parents think they're building their children's confidence, when, in fact, it may be just the opposite. Too much praise can backfire and, when given in a way that's insincere, make kids afraid to try new things or take a risk for fear of not being able to stay on top where their parents' praise has put them.
Still, don't go too far in the other direction. Not giving enough praise can be just as damaging as giving too much. Kids will feel like they're not good enough or that you don't care and, as a result, may see no point in trying hard for their accomplishments.
So what is the right amount of praise? Experts say that the quality of praise is more important than the quantity. If praise is sincere and focused on the effort not the outcome, you can give it as often as your child does something that deserves a verbal reward. “We should especially recognize our children's efforts to push themselves and work hard to achieve a goal,” says Donahue, author of Parenting Without Fear: Letting Go of Worry and Focusing on What Really Matters. “One thing to remember is that it's the process not the end product that matters.”
Your son may not be the best basketball player on his team. But if he's out there every day and playing hard, you should praise his effort regardless of whether his team wins or loses. Praising the effort and not the outcome can also mean recognizing your child when she has worked hard to clean the yard, cook dinner, or finish a book report. But whatever it is, praise should be given on a case-by-case basis and be proportionate （相称的） to the amount of effort your child has put into it.
