Every day it seems that people are coming up with new and innovative ways to use mobile devices like cellphones and smart phones. Researchers at Princeton University are looking for new ways to measure a person's sense of _ with mobile devices. To gain a better understanding of how cellphones and other mobile devices can measure our sense of happiness, the research team conducted a study that was published recently in the journal Demography. To gather data for their study, the team created an application for mobile devices using the Android operating system. Once the app was developed, the researchers invited people to download it and take part in their study. Over a three-week period, the research team was able to collect data from some 270 participants living in 13 countries. Participants came not only from the United States, but also from other nations like Australia, Canada, China, France, Germany, Israel, Japan, Norway, South Korea, Spain, Sweden and the United Kingdom. Over the course of the study, participants received occasional text questions from the researchers that asked "How happy are you?". Along with recording their response, the app used the mobile device's built-in GPS to keep track of the participant's location. The study participants were asked to rate their current state of happiness on a scale of zero to five. As they gathered data from the information collected through the application, the researchers then were able to create new methods that could help provide a better understanding of how our surroundings can influence our emotional well-being. The researchers learned that mobile devices can provide an effective way to quickly grab information that, because of today's active lifestyle, can be difficult to record. Being able to quickly grab this information was something the researchers felt was important. They said feelings and emotions that were recorded as they were happening were most likely to be more honest and precise than using other methods like writing down how they felt on a...

Apple is to open a research lab in the southern Chinese city of Shenzhen, according to Tim Cook, its chief executive, as it seeks to boost sales in the country and improve ties with the authorities. Beijing has been encouraging foreign technology companies to carry out more high-end work on the mainland as part of efforts to revitalize local industry. It will be Apple's second facility in China. It already has a new research and development facility in Beijing. The two R&D centers were "aimed at strengthening relationships with local partners and universities as we work to support talent development across the country", Apple said in a statement. A closer relationship with the Chinese authorities has been a priority following setbacks for the US technology company this year. The iPhone has been losing market share to high-end handsets made by local competitors including Huawei, Vivo and Oppo, which topped the rankings in the second quarter, while Apple languished in fifth place, according to Canalys data. Analysts said the announcement of the R&D centre was Mr. Cook's latest attempt to gain favour with Beijing, following the US group's $1billion investment in Didi Chuxing, the Chinese car-hailing company, in May. Apple has had to change its approach in China as it faces rising nationalism and high-quality local competition, according to Ge Jia, a tech blogger, who wrote yesterday: "It's time for Apple to cast aside their pride." "Their previous strategy of only selling devices to China without leaving anything behind is not working any more and they are starting their process of localisation in China through the Shenzhen lab." According to Ge Jia, what is Apple's previous sales approach in China? A) taking part in high-quality local competition. B) choosing certain customers in China. C) only selling devices. D) selling devices as well as technology.

While I was waiting outside my wife's office building for her to get out of work, I saw a beggar coming my way from across the parking lot. "I hope he doesn't ask me for any money," I thought. He didn't. He came and sat in front of the bus stop, but he didn't look like he could have enough money to ride the bus. After a few minutes he spoke. "That's a pretty car," he said, pointing to my car. He was ragged  , but he had an air of dignity about himself. I gave him a smile and continued cleaning my car. He sat there quietly as I worked. The expected asking for money never came. As the silence between us widened, it seemed that a voice inside me said, "Ask him if he needs any help." I was sure that he would say "yes", but I listened to the inner voice. "Do you need any help?" I asked. He answered in three simple but meaningful words that I shall never forget. We often look for wisdom in great men and women, and we expect it from those of higher learning and achievements. I expected nothing but a dirty hand from him, but he said three words that shook me. "Don't we all?" he said. I was feeling high, successful and important above a beggar in the street, until those three words hit me like a shot. Don't we all? I needed help. Maybe not for a bus fare or for a place to sleep, but I needed help. I reached in my wallet and gave him not only for a bus fare, but enough to get a warm meal and shelter for the day. Those three little words still ring true. No matter how much you have, no matter how much you have achieved, you need help, too. No matter how little you have, no matter how loaded you are with problems, even without money or a place to sleep, you can give help. The story happened   _  . A) outside an office building B) in front of a store C) near a post office D) on a bus
