If you've not heard that the decade-old princess-culture is causing problems—especially if you're a parent—you must be actively working to avoid it.

    The latest study adding fuel to the fire comes out of Brigham Young University and finds that the Disney princess obsession can be harmful to girls.

"I think parents think that the Disney princess culture is safe. That's the word I hear time and time again—it's safe." Lead study author Sarah M. Coyne of the Mormon institution in Utah noted in a press release. "But if we're fully jumping in here and really embracing (accepting) it, parents should really consider the long-term impact of the princess culture."

    So, what's the problem this time around? Same as always, confirmed the study, published in the journal Child Development, which involved the assessment of 198 preschoolers: Lots of engagement with princess culture (whether through moves or toys) can lead to gender-stereotypical(性别定性) behavior as well as self-critical body image.

The strict gender stereotypes can hold girls back. "They feel like they can't do some things," Coyne said, "They're not as confident that they can do well in math and science. They don't like getting dirty, so they're less likely to try and experiment with things."

On the other hand, "Disney princesses represent some of the first examples of exposure to the thin ideal," Coyne said. "As women, we get it our whole lives, and it really does start at the Disney princess level, at age 3 and 4."

So, what should a parent do? Try his or her best to avoid all princesses for the entire of a girl's childhood? I'd say, have moderation in all things, have your kids involved in all sorts of activities, and just have princesses be one of many, many things that they like to do and engage with." Coyne suggested. "This study has changed the way I talk to my daughter, the things I focus on, and it's been really good for me as a parent to learn from this study," Coyne said. "I usually can't say that my research findings have such a personal impact on my life."

    Generally speaking, college graduation brings both the satisfaction of academic achievement and the expectation of a well-paid job. But for 6,000 graduates at San Jose State this year, there's uncertainty as they enter one of the worst job markets in decades.

    Ryan Stewart has a freshly minted degree in religious studies, but no job prospects. “You look at everybody's parents and neighbors, and they're getting laid off and don't have jobs,” said Stewart. “Then you look at the young people just coming into the workforce.., it's just scary.”

    When those graduates entered college, the future never looked brighter. But in the four years they've been here, the world outside has changed dramatically. “Those were the exciting times, lots of dot-com opportunities, exploding offers, students getting top dollar with lots of benefits,” said Cheryl Allmen-Vinnidge, of the San Jose State Career Centre. “Times have changed. It's a new market. The job situation is grim (严峻的) now.” Cheryl Allmen-Vinnidge ought to know. She runs the San Jose State Career Centre, (it is) sort of a crossroads between college and the real world. Allmen-Vinnidge says students who do find jobs after college have done their homework. “The typical graduate who does have a job offer started working on it two years ago. They've postured themselves well during the summer. They've had several internships (实习) ,” she said. And they've majored in one of the few fields that are still hot—like chemical engineering, accounting or nursing—where average starting salaries have actually increased over last year. Other popular fields (like information systems management, computer science, and political science) have seen big declines in starting salaries.

    Ryan Stewart (he had hoped to become a teacher) may just end up going back to school. “I'd like to teach college some day and that requires more schooling, which would be great in a bad economy,” he said.

    It is true more students are able to receive college education. It is also true that they will have to face fiercer competition in the job market as they graduate. It becomes harder and harder for the current graduates to get a foothold in job markets, but many of them have no choice but to follow the beaten track. To some students a degree may not be ticket to instant wealth. For now, they can only hope its value will increase over time.

    Obama, Lady Gaga and Steve Jobs—what do they have in common? They are, of course, all Americans. And according to a survey by social networking site baidu. com, they all best illustrate(举例说明) the word “cool”.

    But just what does it mean to say someone is “cool”? Most would answer that it is something to do with being independent-minded and not following the crowd.

    Yale University art professor Robert Farris Thompson says that the term “cool” goes back to 15th century West African philosophy. “Cool” relates to ideas of grace under pressure.

    “In Africa,” he writes, “coolness is a positive quality which combines calmness, silence, and life.”

    The modern idea of “cool” developed largely in the US in the period after World War II. “Post-war 'cool' was in part an expression of war-weariness (厌战情绪), . . . it went against the strict social rules of the time,” write sociologists Dick Pountain and David Robins in Cool Rules: Anatomy of an Attitude.

    But it was the American actor James Dean who became the symbol for “cool” in the hugely successful 1955 movie Rebel without a Cause. Dean plays a tough guy who disobeys his parents and the authorities. He always gets the girl, smokes cigarettes, wears a leather jacket and beats up bullies. In the movie, Dean showed what “cool” would mean to American young people for the next 60 years.

    Today the focus of “cool” has changed to athletics (体育运动) stars. Often in movies about schools, students gain popularity on the athletics field more than in the classroom. This can be seen quite clearly in movies like Varsity Blues and John Tucker Must Die.

    But many teenagers also think being smart is cool. Chess and other thinking games have been becoming more popular in schools.

    “Call it the Harry Potterization of America—a time when being smart is the new cool,” writes journalist Joe Sunnen.

    Does the future of filmmaking lie in virtual reality (VR) films?

    An ambitious team led by Yale senior Celine Tien might hold the answer to that question.

    Tien produced,directed and acted in Pippa's Pan,which she says is “one of the world's first live-action VR films.”The film,which was completed in April,mixes live action with VR sections.Some of the characters were created via animation（动画）and other techniques that distinguish the film from 360° VR videos like the ones frequently seen on YouTube.

    “360° VR videos are stagnant,which means you don't move with them and see a 360° view of whatever they're filming.”Tien explained.“What we're doing is immersive（沉浸式的）VR.When you put on the goggles (a kind of special glasses) you can physic.ally walk around in the space,pick up objects and engage with the environment.It's a huge difference.”

    The immersive VR film experience is different for everyone who interacts with the medium,but that doesn't mean the film's ending will change for each viewer.

    The film stars two Chinese-speaking actors."It's a love story about a woman suffering from Alzheimer's disease who is trying to bring back memories of her husband,"Tien said.

    The film has already been recognized by the VR industry.After handing in a short demo to the AT&T Developer Summit Conference,Tien and her team were invited to Las Vegas in January,where they came in third place.

    If you're dying to see the film already,your choices area bit limited: Pippa's Pan can't be seen in movie theaters unless they happen to have VR goggles available.According to Tien,many theaters in China will soon have the ability,which makes sense considering China is the film's target market.

    Pippa's Pan will be released in three languages: Chinese,English and Korean.“It can get spread in different ways: at film festivals with VR set ups and through HTC or Oculus headset stores,”Tien says.“If you have VR goggles you can download it and experience it yourself.We will also cooperate with movie theaters that have VR set ups.”

    First aid is emergency care for a victim of sudden illness or injury until more skillful medical treatment is available. It may save a life or improve certain vital signs including pulse, temperature，a clear airway(气道), and breathing. In minor emergencies，first aid may prevent a victim's condition from turning worse and provide relief from pain. First aid must be   administered as quickly as possible. In the case of the Critically injured, a few minutes can make a difference between complete recovery and loss of life.

    First­aid measures depend upon a victim's needs and the provider's level of knowledge and skill. Knowing what not to do in an emergency is as important as knowing what to do. Improperly moving a person with a neck injury, for example，can lead to permanent spinal (脊柱的) injury and  paralysis (瘫痪)．

    Despite the variety of injuries possible, several principles of first aid apply to all emergencies. The first step is to call for professional medical help. The victim, if conscious（有意识的）, should be reassured that medical aid has been requested，and asked for permission to provide any first aid.  Next，assess the scene, asking other people or the injured  person's family or friends about details of the injury or illness，any care that may have already been given, and preexisting conditions such as diabetes (糖尿病) or heart trouble. The victim should be checked for a medical bracelet (手镯) or card that describes special medical conditions. Unless the accident scene becomes unsafe or the victim may suffer further injury，do not move the victim.

    First aid requires rapid assessment of victims to determine whether life­threatening conditions exist. One method for evaluating a victim's condition is known by the acronym(首字母缩写词)ABC，which stands for：

    A—Airway: Is it open and clear?

    B—Breathing: Is the person breathing? Look, listen, and feel for breathing.

    C—Circulation: Is there a pulse? Is the person bleeding externally? Check skin color and temperature for additional indications of circulation problems.

    Microsoft has developed a new smart phone app that interprets eye signals and translates them into letters, allowing people with motor neurone disease to communicate with others from a phone.

    The GazeSpeak app combines a smartphone's camera with artificial intelligence to recognize eye movements in real time and convert(改变) them into letters, words and sentences.

    For people suffering from ALS（渐冻症）, also known as motor neurone disease, eye movement can be the only way they are able to communicate.

    “Current eye-tracking input systems for people with ALS or other motor impairments are expensive, not robust under sunlight, and require frequent re-calibration and substantial, relatively immobile setups,” said Xiaoyi Zhang, a researcher at Microsoft who developed the technology.

    “To mitigate the drawbacks…we created GazeSpeak, an eye-gesture communication system that runs on a smartphone, and is designed to be low-cost, robust, portable and easy to learn.”

    The app is used by the listener by pointing their smartphone at the speaker. A chart that can be stuck to the back of the smartphone is then used by the speaker to determine which eye movements to make in order to communicate.

    The sticker shows four grids(方格) of letters, which each correspond to a different eye movement. By looking up, down, left or right, the speaker selects which grids the letters they want belong to. The artificial intelligence algorithm（程序） is then able to predict the word or sentence they are trying to say.
