Fighting racial stereotypes（模式化）on US campuses often begins by putting students of different ethnic backgrounds together — under one dormitory roof.

    Sam Boakye was a freshman at Ohio State University and the only black student on his floor. He was determined to get good grades — in part to make sure his white roommate had no basis for negative racial views. "You're pushed to do better, to challenge the stereotype that black people are not that smart," he told the New York Times.

    Several recent studies have found that having a roommate of a different race can reduce prejudice(偏见), diversify(使多样化) friendships and even promote students' academic performance. In a study by Ohio State psychology professor Russell Fazio, black freshmen who came to college with high test scores earned better grades if they had a white roommate—even if the roommate's test scores were low. Another study on student interaction by Duke University suggests that freshmen with roommates of a different race were the most likely to diversif“y their friendships. Just having diversity in classrooms doesn't do anything to increase interracial friendships," said Claudia Buchman, an author of the Duke study. “But living together with a different-race roommate does lead to more interracial friendships."

    There are, however, some problems with such room assignments. Fazio's study found that three times as many randomly(随机地) assigned interracial roommates weren't living together at the end of the semester, compared with white roommates. Interracial roommates also spent less time together, had fewer joint activities and were less involved with each other's friends than white pairs.

    As for Boakye, this is not the case. "A lot of white students come without much exposure（暴露）to diversity, so when their first interaction with a black guy isn't bad, they will make more black friends. I think I made a good impression on my freshman roommate. I saw him this year, and he said, "Hey dude, you're not the only black friend I have. That felt good."

    If you have ever been left wondering why your emails are riddled(充斥着) with grammatical errors, or why you can never quite find the right phrase, it may be because you are typing with both hands.

    Our vocabulary becomes richer and our writing style becomes more fluent when we type using just one hand, scientists have found. "Typing can be too fluent or too fast, and it can actually weaken the writing process," said Srdan Medimorec, the lead author of the study conducted at the department of psychology at the University of Waterloo, Canada. "It seems that what we write is a product of the interaction(互动) between our thoughts and the tools we use to express them."

    Using text-analysis software, researchers asked 103 university students to write essays under different conditions, using one hand to type and using both hands to type. The software was used to analyze(分析) elements of the essays, such as range of vocabulary, sentence complexity and the cohesion(衔接) of the writing.

    Researchers found that participants' vocabulary became more advanced when they typed with one hand rather than two. The research team said that by slowing our writing down, typing one-handed allows more time for an internal (内在的) word search, resulting in a larger variety of words.

    In contrast, fast typists might just write the first word that comes to mind. However, it is important not to slow typing down too much. Those who typed essays one-handed in the current study slowed down to about the speed of handwriting.

    This is the first study to show that changing people's typing can make their writing get better. The researchers suggested that the speed of writing could affect writing quality regardless of the tools used, whether they are computers, or pen and paper, although further research would be required to prove that idea.

Room 3

    As well as shoes and boots,the museum also exhibits shoe-shaped objects.The variety is unbelievable.For example,there is a metal lamp that resembles a pair of shoes,and Greek wine bottles that like legs!

The Footwear Library

    People come from all over the world to study in our excellent footwear library.Designers and researchers come here to look up information on anything and everything related to the subject of footwear.

    WHAT PEOPLE ARE SAYING

    "Extremely pleased with my personal alarm system .I feel much safer in my everyday life having it in my pocket or handbag. A friend recently had an unsettling experience in an outdoor parking lot of a grocery store, so I ordered this product for her. She was delighted to receive it and to have the added protection and peace of mind it offers."

    —Jillian Thompson from Chicago, IL "Oh my WORD! This is SO loud! It's perfect to call attention to an unwanted situation or to call attention to anything where you may need assistance. I got myself one and one for each of my kids. The pin releases easily BUT it doesn't seem to just fall out either so you can carry with ease and won't have to worry about setting it off. But if you do, it's easy to slip it right back in. Haha! A little pull will give you a real good idea what it's capable of, I promise."

    —Angela Kelley from Palo Alto, CA "Bought three for the young women in our family .They were all very happy with the ease of use and how LOUD it is. Would definitely buy again."

    —Billy Perkins from Indianapolis, IN Are you ready to protect yourself and your loved ones from the bad guys?

At some point, something will have to be done about the stuffed toys（毛绒玩具）. I haven't counted them because, truthfully, I'm not prepared to know how many there are. Lately, our neighborhood's message boards are filled with posts about parents trying to make space, to clear out the things their kids no longer need. The tone of some of these posts can best be described as "emergency". "Help!" they sometimes begin. "I have to get this out of my house."

"The proliferation（激增）of children's toys is the outcome of a long, gradual cultural change," says Gary Cross, a professor at Pennsylvania State University. To understand how we got here—drowning（淹没于）in all those stuffed toys and bricks—it helps to look as far back as the late 19th century. "Parents were no longer passing their jobs on to the children," Cross says. "Instead, they connect across generations through the gifting process. From the early 20th century on, goods became the things that define relationships between family members, and the way of marking success as a family."

Then, how can parents deal with the proliferation of children's toys at home? Naeemah Ford Goldson, a professional organizer, is also a mom of two. In her own home, Goldson likes to include her kids in the work of sorting out their toys. They know that the items they don't need anymore will be given to people who can use them, to families who might not be as fortunate as theirs. "Doing so helps them build those habits of letting go," she says, "so then they don't become adults who are too dependent on material things instead of experiences, or people, and the memories we make with people."

Her idea made sense. She told her 5-year-old they should pick some to give to kids in their community who came from another country and had to leave their toys behind. She immediately took a pink bear from the pile.
