I first came across the concept of pay-what-you-can cafes last summer in Boone, N.C., where I ate at F.A.R.M (Feed All Regardless of Means) Café. You can volunteer to earn your meal, pay the suggested price($10) or less, or you can overpay—paying it forward for a future customer's meal. My only regret after eating there was not having a chance to give my time. So as soon as Healthy World Café opened in York in April, I signed up for a volunteer shift(轮班).

    F.A.R.M and Healthy World are part of a growing trend of community cafés. In 2003, Denise Cerreta opened the first in Salt Lake City. Cerreta now runs the One World Everybody Eats Foundation, helping others copy her pay-what-you can model.

    “I think the community café is truly a hand up, not a handout,” Cerreta said. She acknowledged that soup kitchens(施粥所) have a place in society, but people typically don't feel good about going there.

    “One of the values of the community café is that we have another approach,” she said. “Everyone eats here, no one needs to know whether you volunteered, overpaid or underpaid.”

    The successful cafés not only address hunger and food insecurity but also become necessary parts of their neighborhood – whether it's a place to learn skills or hear live music. Some teach cooking to seniors; some offer free used books. Eating or working there is a reminder that we are all in this world together.

    My 10 am—1pm shift at World-Healthy-Café began with the café manager — one of the two paid staff members. Our volunteer crew wasn't the most orderly, but we managed to prepare and serve meals with a lot of laughs in between. At the end of my shift, I ordered my earned meal at the counter, together with other volunteers. After lunch, I walked out the door, with a handful of new friends, music in my head and a satisfied belly and heart.

    It's surprising how much simple movements of the body can affect the way we think. Using expansive gestures with open arms makes us feel more powerful, crossing your arms makes you more determined and lying down can bring more insights(领悟).

    So if moving the body can have these effects, what about the clothes we wear? We're all well aware of how dressing up in different ways can make us feel more attractive, sporty or professional, depending on the clothes we wear, but can the clothes actually change cognitive (认知的) performance or is it just a feeling?

    Adam and Galinsky tested the effect of simply wearing a white lab coat on people's powers of attention. The idea is that white coats are associated with scientists, who are in turn thought to have close attention to detail.

    What they found was that people wearing white coats performed better than those who weren't. Indeed, they made only half as many errors as those wearing their own clothes on the Stroop Test (one way of measuring attention). The researchers call the effect “enclothed cognition,” suggesting that all manner of different clothes probably affect our cognition in many different ways.

    This opens the way for all sorts of clothes-based experiments. Is the writer who wears a fedora more creative? Is the psychologist wearing little round glasses and smoking a cigar more insightful? Does a chef's hat make the resultant food taste better?

    From now on I will only be editing articles for PsyBlog while wearing a white coat to help keep the typing error count low. Hopefully you will be doing your part by reading PsyBlog in a cap and gown (学位服).

    My college experience included this life-skill lesson: Drink alcohol on a full stomach. Or you will get inebriated too quickly. Of course, most college students shouldn't be drinking at all, but we know from the National Institute on Alcohol Abuse and Alcoholism that close to 60 percent of college students aged 18 to 22 do consume alcohol, which makes harm-reducing approaches important.

    Unfortunately, campus authorities and researchers are reporting a practice that turns the full-stomach drinking strategy on its head: rather than filling up before a night of partying, significant numbers of students refuse to eat all day before consuming alcohol.

    This is a high-risk behavior called "drunkorexia," which is one part eating disorder, one part alcoholism—a very dangerous combination for college-age students. The term drunkorexia, which can also include excessive exercise or purging before consuming alcohol, was coined about 10 years ago, and it started showing up in medical research around 2012. Drunkorexia addresses the need to be the life of the party while staying extremely thin, pointing to a flawed mind-set about body image and alcoholism among college students, mostly women.

    Imagine this scenario: A female college freshman doesn't eat anything all day, exercises on an empty stomach, then downs five shots of tequila in less than two hours. Because there's no food in her system to help slow the absorption of alcohol, those shots affect her rapidly, leading to inebriation and possibly passing out, vomiting or suffering alcohol poisoning. That's drunkorexia.

    Tavis Glassman, professor of health education and public health at the University of Toledo in Ohio, researches drunkorexia and worries about scenarios such as the one described above: "With nothing in her system, alcohol hits quickly, and that brings up the same issues as with any high-risk drinking: getting home safely, sexual assault, unintentional injury, fights, hangovers that affect class attendance and grades, and possibly ending up in emergency because the alcohol hits so hard," he says.

    "Alcohol can negatively affect the liver or gastrointestinal system, it can interfere with sleep, lower the immune system and is linked to several types of cancers," Hultin says.

    Surgery that can improve the way a person looks is being more and more popular in the United Stated. This kind of surgery is called cosmetic surgery, and both men and women are turning to this treatment as a way of keeping their appearance young as well as keeping competitive in their jobs. Men especially are beginning to turn to face-lifts, liposuction, and implants to help them look younger. As companies downsize and move younger employees into higher positions, older employees in their late forties and early fifties feel the need to look and act younger in order to stay competitive. A younger look through cosmetic surgery may give an older employee a few more years on the job.

    These operations are not without dangers, however. One young woman had an eye operation to get rid of the bags under her eyes. She described her experience as terrible. She said, "When he started cutting, I was fully awake. Even though he'd given me an injection(注射) near my eyes, I saw everything. "She went on to explain, "I knew I had to keep still because of what he was doing. He was removing fat under my eyes. It took about ten minutes. After he finished I felt I couldn't walk. I was so weak." Her troubles did not end after the operation. For two weeks, her eyes were swollen and almost completely closed, and even dark glasses could not hide the side effects of the operation.

    Liposuction is probably the most popular cosmetic operation in the United States. It seems simple enough. First, a small cut is made over the places where the patient wants the fat removed. Next, a small pipe is put into the cut. A machine is then turned on, and the fat is taken right out of the body. However, as one doctor explained, some problems can happen after the operation. He warned, "Irregular lumps(块) and loose skin can result from this operation. If it is not completely done, liposuction can produce a very lumpy result." Patients often must have more liposuctions to correct the problem.

Scholastic Art & Writing Awards

The Scholastic Art & Writing Awards are among the most famous awards for student achievement in the literary and visual arts. Past winners include such short story masters as Donald Barthelme, Joyce Carol Oates, and Stephen King.

The contest offers several categories relevant to short story writers: short story, flash fiction, science fiction, humor, and writing collection (graduating seniors only).

Who can enter? The contest is open to students in grades 9 to 12 (including homeschool-ers) in the US, Canada, or American schools abroad.

What do winners receive? The contest offers a variety of scholarships (some as high as $ 10,000) and cash awards (some as high as $ 1,000) at both the regional level and he national level. Winners may also receive certificates of recognition and opportunities for publication.

How are entries judged? The awards have three judging standards: originality, technical skill, and the reflection of a personal vision or voice. Be sure to read past winners to get an idea of what's been successful. The judges change every year, but they always include people who are highly accomplished in their field.

When is the deadline? Competition guidelines are updated in September, and submissions are usually accepted from September through early January. Regional Gold Key winners will automatically advance to the national competition.

How do I enter? All students begin by entering a regional competition based on their ZIP code. See the guidelines for additional information.

The ancient Chinese built two great engineering wonders: the Great Wall and the Grand Canal. Though the Great Wall's effect in military {#blank#}1{#/blank#} (defend) has worn off over time, the Grand Canal remains an important channel of cultural communication.
