Secrets of Web Travel Sites

Booking a trip on an online travel siteis convenient, but comes with its own set of problems.

1 They who's on a Mac and who's on a PCand who's going to spend more.

Last year, US travel research companyOrbitz tracked people's online activities to test out whether Mac users spendmore on travel than PC users. On average, Mac users lay out US$20-30 more pernight on hotels and go for more stars. according to the Wall Street Journal. Asa result, online• travel sites show these users more expensive travel optionsfirst. To avoid inadvertently paying more, sort results by price.

 Their software doesn't always hook up to thehotel's system.

A guaranteed reservation is almostimpossible to come by anywhere — but the risk of your flight or hotel beingoverbooked increases with third-party providers. The middle-man's softwareisn't immune to system errors, so always call the hotel or airline to make sureyour booking was processed.

 Don't be fooled by packages: Often, they'relow-end items grouped together.

Ever notice how travel sites recommend ahotel, a rental car, and tour package all in one click? These deals usuallyfeature travel that no one wants, like flights with multiple layovers.

Check the fine print.

 You could miss out on loyalty points.

Third-party providers can get betweenyou and frequent flyer miles or points. Many hotel loyalty programmes don'trecognise external sites, others award only minimum points and exclude specialoffers, like double points on hotel stays.

 Once your trip is purchased, you're on yourown.

An online travel agency can't provideassistance the same way an agent can if a flight is cancelled or a room issubstandard. Basically, when you arrive at the airport or hotel, you're justanother client who booked at the lowest rate.

Uncle Tom's Cabin

    Uncle Tom's Cabin is an anti-slavery novel by American author Harriet Beecher Stowe. Published in 1852, the novel “helped lay the base for the Civil War”, according to Will Kaufman. When Abraham Lincoln met Stowe at the start of the Civil War, Lincoln declared, “So it is the little lady who started this great war.” The character of Uncle Tom in the novel is a longsuffering black slave. The sad novel exposes the reality of slavery.

Gone with the Wind

    Gone with the Wind is a novel by Margaret Mitchell in 1936. It tells the story of Scarlett O'Hara, and her adventures in the American South during the Civil War. She falls in love with Rhett Butler, a city gentleman. It is one of the most famous books of its time, and was made into a movie with the same name. The title took its name from the lines an Ernest Dowson poem: “I have forgotten much, Cynara! Gone with the wind.” (This line also appears in the book.)

    Whether in the home or the workplace, social robots are going to become a lot more common in the next few years. Social robots are about to bring technology to the everyday world in a more humanized way, said Cynthia Breazeal, chief scientist at the robot company Jibo.

    While household robots today do the normal housework, social robots will be much more like companions than mere tools. For example, these robots will be able to distinguish when someone is happy or sad. This allows them to respond more appropriately to the user.

    The Jibo robot, arranged to ship later this year, is designed to be a personalized assistant. You can talk to the robot, ask it questions, and make requests for it to perform different tasks. The robot doesn't just deliver general answers to questions; it responds based on what it learns about each individual in the household. It can do things such as reminding an elderly family member to take medicine or taking family photos.

    Social robots are not just finding their way into the home. They have potential applications in everything from education to health care and are already finding their way into some of these spaces.

    Fellow Robots is one company bringing social robots to the market. The company's “Oshbot” robot is built to assist customers in a store, which can help the customers find items and help guide them to the product's location in the store. It can also speak different languages and make recommendations for different items based on what the customer is shopping for.

    The more interaction the robot has with humans, the more it learns. But Oshbot, like other social robots, is not intended to replace workers, but to work alongside other employees. “We have technologies to train social robots to do things not for us, but with us,” said Breazeal.

    How does a sunset work? We love to look at one, but Jolanda Blackwell wanted her eighth-graders to really think about it and question.

    So Blackwell had her students watch a video of a sunset as part of a physics lesson on motion. "I asked them: ' So what's moving And why' " Blackwell says. Some thought the sun was moving; others knew that a sunset is the result of the Earth spinning around on its axis. "Usually, my biggest challenge is trying to keep them patient," she says. "They just have so many burning questions."

    "Every day, we meet new information," says Charan Ranganath, a psychologist. Ranganath was curious to know why we keep some information and forget other things. So he got 19 volunteers and asked them to review more than 100 questions. When the participants' curiosity was aroused, the parts of' their brains that regulate pleasure and reward lit up. Curious minds also showed increased activity in the brain, which is involved in greater memories.

    "Curious brains are better at learning not only about the subject at hand but also dull information. This is a phenomenon teachers can use in the classroom," says Evie Malaia, a professor. "Say a kid wants to be an astronaut," she says. NL Well, how do you link that goal with learning multiplication tables(乘法表)" "A teacher may choose to ask her class an interesting word problem that involves space exploration," Malaia says. Students may remember the answer to the word problem, but they'll also remember how they found the answer through multiplication.

    What Ranganath wants to know most is why some people seem naturally more curious than others. Lots of factors, including stress, aging and certain drugs  affect dopamine(多巴胺) processing in the brain. "If we could figure these things out, we could help those who may just seem bored," Ranganath says.

    Blackwell says she doesn't have to deal with that problem too often. She says her students love exploring the mysterious unknowns in science: What happens when a car crashes. How do rainbows work "I tell my kids there's no dumb questions," Blackwell says. "That's science: asking questions and seeking answers."

Instagram(图片分享社交应用程序)is about to take its biggest step toward removing likes from its platform. After months of testing an option to hide likes in select international markets, Instagram, which is owned by Facebook(FB), has already been testing hiding likes in seven other countries, including Canada, Ireland and Australia. For years, likes have been central to how celebrities, brands, politicians and everyday users experience Instagram and Facebook. It's a way of measuring popularity(名气) and success. But in recent months, Instagram has been rethinking how likes contribute to making its platform more toxic. Now it's considering a change.

The total number of likes on posts — which appear as hearts on the app—will disappear from Instagram's main feed, profile pages and permalink(永久链接)pages. The owner of the account can still see their own likes, but their followers won't know the count.

CNN Business previously spoke with users in countries with the test. The majority felt this move would improve well-being on the app. Instagram is the most harmful social networking app for young people's mental health, such as negatively influencing body image, according to one study.

But other users and psychologists said hiding likes won't fix everything. The test doesn't address some of the key ways that activity on Instagram can influence the well-being of users, including bullying(欺凌), feeling left out and thinking other people's lives are better than their own.

Renee Engeln, a psychology professor at Northwestern University, voiced his opinion that the biggest impact of Instagram is the content and the exposure to this constant stream of perfected images is what seems to hurt psychologically. Plus, users can still see their own likes—and feel badly if their posts don't perform well.

According to a new research,the more people in a country who have a particular gene(基因),the happier the nation will be.This DNA is known as the FAAH gene.People with a particular version of it tend to be cheerier souls.There is a link between levels of the FAAH gene and the number of people who say they are very happy.

Sweden—one of the happiest countries in the world—also has lots of happy DNA.Ghana,Nigeria,Mexico and Columbia all come out near the top in the happiness league,and have high rates of the gene.In contrast,the people of Iraq,Jordan and China are among the least likely to rate themselves as very happy and also have the lowest level of the FAAH gene.

However,wealth and health are found to have little effect on happiness.The finding could help explain why some of the world's poorest nations are also the happiest.In addition,the FAAH gene and an optimistic attitude would not always go hand in hand.For example,Russians and Estonians score very low in happiness,despite having the right happy DNA.

Professor Michael Minkov said,"The climate condition is associated with the nation's happiness.We can notice the high occurrence of the FAAH gene in tropical(热带的) areas in the Americas and Africa.And the occurrence of the gene around the Mediterranean Sea is much lower than that in Northern Europe."

The social experts say that genetics is not the only determinant(决定因素) of happiness.The economic and political difficulties in some nations also contribute to the very low happiness scores.Nations that are not blessed with the right DNA aren't necessarily miserable.
