Article: Meet Jeff Wilson AKA Professor Dumpster , an environmental scientist and the Dean of Huston Tillotson University in Austin, Texas. The reason for his unusual nickname? He has decided to live in a dumpster for the next year. Yes, the kind that you might find filled with trash behind a restaurant. Wilson says the inspiration to do something first hit him two years ago, when he was working on an article at a neighborhood coffee shop and caught sight of an eight-yard dumpster. Now that he has found one, Professor Dumpster is putting his students to work. After all, the point of this project isn't just to spend his life living out of a garbage can: there is, a much greater purpose involved. As an environmental scientist, the professor constantly thinks about sustainable living and how every person should try to minimize his/her impact on our already stretched resources. That, is the challenge Wilson wanted his students to step up to, this entire year. Using their math, science, engineering and technology skills, he wants them to retrofit his 33 square-foot dumpster into a modern space that includes a shower, a toilet, a kitchen and a bed and is fitted with conveniences like air-conditioning and even WiFi. The demand? It all has to be green and sustainable. www.ks5u.com So why is Wilson planning to go through such hardship? That is because he wants to equip his students with the tools to survive in a world that is rapidly heading towards a population of 10 billion people. A large majority of the population adjust to living in tighter spaces in the world where resources and space should be limited to be used. By promoting awareness and education on these subjects, Wilson is helping students everywhere see that living "small" and sustainably is certainly possible. And while the dumpster project may seem a little crazy to some, the professor thinks of it as a "playful and imaginative" educational experiment and conversation-starter to discuss the fact that all of us can do with less as we move into the future.
Answer: Finding sustainable living ways of using fewer resources.
What is Jeff Wilson concerned about all the time?

Article: Imagine a picnic dinner held at a location only made known hours before the meal, where guests are invited to decorate tables and chairs, bring their favorite dishes and wear white to reflect the simplicity of the event. This was the scene at a PopUp dinner held on June 13 in Brooklyn, New York's Prospect Park. PopUp dinners are popping up nationwide -- not just in Brooklyn. Garrett Sathre and his wife and business partner, Nicole Benjamin-Sathre are the team behind Hand Made Events and the creators and hosts of PopUp dinners. Sathre, a former restaurateur and head chef with Bubba's Diner and Kitchen 39, both located in the Bay Area, came up with the concept of the flash dinner after he was inspired by the annual Diner en Blanc held in Paris. In 2011, Hand Made Events used the power of social media to get the word out and soon, enough interest was attracted. In October 2011, it held its first flash dinner, calling the evening Le Diner a San Francisco at Golden Gate Park's outdoor Music Pavilion. He described it as a picnic dinner for 3,500 people."I thought we would have anywhere between 300-500 people to attend. Two articles ran a week later about my crazy idea and we got 15,000 emails within three days,"Sathre said. After the success of the San Francisco dinner, Sathre decided to expand his"crazy idea"and hold dinners across the country in major markets such as Brooklyn, Los Angeles and San Francisco. Sathre says their Brooklyn PopUp on June 13 sold 5,000 tickets in just four days with 5,000 on the waiting list raising over $160,000 in ticket sales. Those are some big numbers. Hand Made Events partners with the Prospect Park Alliance and gives all of their proceeds to the non-profit group. In total, the Brooklyn PopUp dinner raised over $60,000 for the Prospect Park Alliance. Hand Made Events sees the same interest in their smaller city locations."We have seen a 30 percent increase in our smaller markets -- Minneapolis, San Diego, Charleston, and Miami every year,"Sathre said. Hand Made Events has eight more dinners planned nationwide this year, and six already scheduled for next year. The popularity is not just here in the states. Sathre says he sees photos of other groups holding similar events everywhere through social media. Just last year, Hand Made Events helped a woman in Kenya plan her own flash dinner via Skype."This event crosses and appeals to all cultures. There are not many events, if any, that bring all people together like the PopUp,"he said.
Answer: Popular and simple.

Article: As the summer time approaches, more and more commercials and advertisements can be seen on the mass media encouraging students to join English study tours abroad. The purpose of these tours is to provide students with an opportunity to learn English in a native speaking environment and use English in real situations. Parents always believe that their children will automatically speak good English after attending these study tours. However, for me, as an English major and former participant of many English study tours, I find these summer tours ineffective. Parents who send their children abroad for a summer to study English usually believe that the native speaking environment, including the courses, teachers, and host families, can help their children to learn English better. This might be true if the students really study hard and they really get an all-English environment. But the fact is that, most of the time, the tour part is more important than the study part. Although these tours take place in foreign countries, students are rarely exposed in an all-English environment. You will find that, in the morning classes, Taiwanese students would like to stick together and speak Chinese with each other, even though there are some students from other countries. In the afternoon, the students go on a sightseeing excursion with their companions from Taiwan; they speak Chinese of course. In the evening, when students return to the host families, they would stay in their room and share the day with their roommate, another Taiwanese student. People who speak the same language with you is like a log in the ocean when living in a foreign country where you can not express yourself well, so that you would naturally stick with them. This is especially true with children. Another unrealistic expectation parents have for these tours is that the experience of living abroad can make their children more independent and mature. However, maturity does not come overnight. It takes time and practice. The most important of all is that they need a good _ . None of these exist in the study tours.
Answer: Neutral.
