University Room Regulations

    Approved and Prohibited Items

    The following items are approved for use in residential (住宿的) rooms: electric blankets, hair dryers, personal computers, radios, televisions and DVD players. Items that are not allowed in student rooms include: candles, ceiling fans, fireworks, waterbeds, sun lamps and wireless routers. Please note that any prohibited items will be taken away by the Office of Residence Life.

    Access to Residential Rooms

    Students are provided with a combination (组合密码) for their room door locks upon check-in. Do not share your room door lock combination with anyone. The Office of Residence Life may change the door lock combination at any time at the expense of the resident if it is found that the student has shared the combination with others. The fee is $25 to change a room combination.

    Cooking Policy

    Students living in buildings that have kitchens are only permitted to cook in the kitchen. Students must clean up after cooking. This is not the responsibility of housekeeping staff. Kitchens that are not kept clean may be closed for use. With the exception of using a small microwave oven (微波炉) to heat food, students are not permitted to cook in their rooms.

    Pet Policy

    No pets except fish are permitted in student rooms. Students who are found with pets, whether visiting or owned by the student, are subject to an initial fine of $100 and a continuing fine of $50 a day per pet. Students receive written notice when the fine goes into effect. If, one week from the date of written notice, the pet is not removed, the student is referred to the Student Court.

    Quiet Hours

    Residential buildings must maintain an atmosphere that supports the academic mission of the University. Minimum quiet hours in all campus residences are 11:00 pm to 8:00 am Sunday through Thursday. Quiet hours on Friday and Saturday nights are 1:00 am to 8:00 am. Students who violate quiet hours are subject to a fine of $25.

    For grown-ups, an afternoon snooze(打盹) is often easier said than done. But many of us have probably experienced just how simple it can be to catch some sleep in a gently rocking hammock(吊床). By examining brain waves in sleeping adults, researchers reported in the June 21 issue of Current Biology, a Cell Press publication, that they now have evidence to explain why that is.

    “It is a common belief that rocking causes sleep: we fall asleep in a rocking chair soon and, since ancient times, we cradle our babies to sleep,” said Sophie Schwartz of the University of Geneva. “Yet, how this works had remained a mystery. The goal of our study was made up of two parts: to test whether rocking does indeed improve sleep, and to understand how this might work at the brain level.”

    Schwartz, Michel Mühlethaler, and their colleagues Laurence Bayer and Irina Constantinescu asked twelve adult volunteers to nap on a custom-made bed or “experimental hammock” that could either remain still or rock gently. All participants were good sleepers who didn't typically nap and did not suffer from excessive sleepiness during the day. Each participant took two 45-minute afternoon naps, one with the bed still and one with the bed in motion, while their brain activity was monitored.

    “We observed a faster transition to sleep in each and every subject in the swinging condition,” Mühlethaler said. “Surprisingly, we also observed a dramatic boosting of certain types of sleep-related brain waves.”

    More specifically, rocking increased the length of stage N2 sleep, a form of non-rapid eye movement sleep that normally occupies about half of a good night's sleep. The rocking bed also had a lasting effect on brain activity, increasing slow brain waves and bursts of activity known as sleep spindles(纺锤体).

    Schwartz and Mühlethaler say the next step is to find out whether rocking can improve longer periods of sleep and to find out whether it may be useful for the treatment of sleep disorders, such as insomnia(失眠).

    Robots make me nervous — especially the ones which seem to think for themselves. I was embarrassed to admit this till I heard that Bill Gates, the founder of Microsoft, felt the same way.

Gates said in an interview with the social networking and news website Reddit: "I am in the camp that is concerned about super intelligence. First the machines will do a lot of jobs for us and not be super intelligent. That should be positive if we manage well. A few decades after that though the intelligence is strong enough to be a concern."

    Well, maybe I don't have to worry about my computer and kitchen equipment yet. After I use them I can always pull the plug. But in the future, machines might find a way to prevent us from switching them off. There's a terrible thought!

    Maybe the problem with computers too clever for us is not that they are evil like some we've seen in sci-fi movies. What could put us in danger is that they might be too efficient. That's what philosopher Nick Bostrom from Oxford University believes. He says that machines are indifferent to humans and in pursuit of their own goals, the destruction of people might be just additional damage. Bostrom gives us an example: A machine which might have as its only goal to produce as many paperclips as possible might look at human bodies as extra material for paperclips and go after you. Because it is, well, a machine, it would not take pity on you.

    It's a good thing that American writer Isaac Asimov thought about how far robots can go and left us his three rules of robotics. They state that a robot may not hurt a human being or allow the human being to come to harm.

I'm glad my machines at home are "dumb". All my cleaner wants to take over is the carpet in my living room. Let's hope they don't create an appliance which wants to take over the world!

    They say the average person makes 35, 000 decisions a day. Yet in her new book, How Woman Decide, Therese Huston explores a widespread phenomenon that many women fail to notice. "There's a huge double standard when it comes to how men and women are viewed as decision﹣makers," explains Therese, a psychologist from Seattle University. Therese decided to write the book after looking at her bookshelf: At one end, there were bestselling books about how to be a clever decision﹣maker ﹣ all written by men and featuring interviews with men like athletes. At the other end were books aimed at women on gaining leadership skills and confidence.

    "Once those women are at the table, will their decisions be taken as seriously as men's？" Therese wondered. "Men are respected as decision﹣makers more than women, especially in the workplace, largely because there's this cultural belief that women are unable to make smart choices at work. "

    So, Therese set out to pick apart the stereotypes（固有印象）to see what scientific research had found. "Scientific research shows that men and women struggle with decision-making equally. The only disadvantage I found was that during the teenage years-teenage girls are more indecisive than teenage boys. Otherwise, there's little difference between the genders（性别）.

    However, there are some differences. "Women are more collaborative（协作的）, "says Therese. "A female boss is more likely to ask the opinions of those around her when making a choice. Women ask for input, which helps make better decisions. However, this is often seen as a weakness rather than a strength.

    Therese also found that during times of stress, men and women make different choices, and the outcomes are often better when women are involved.

    Study after study backs this view up. Neuroscientists Mara Mather and Nicole Lighthall from the University of Southern California studied the way men and women make decisions and found that in times of stress, they react very differently.

    During their study, which involved playing a virtual gambling（赌博）game, they found that when the females became stressed, they made smart decisions ﹣ quitting while they were ahead or taking safe bets. But when the men became stressed, they did the opposite, risking everything for a slim chance of a big win.

    Albert Einsein said," Only a life lived for others is worth living."

How does this job offer sound? You'll need to be available on short notice，including late at night and on weekends. You could be asked to do anything from helping at community events to responding to life-threatening emergencies (sometimes putting your own safety at risk). This job also involves a lot of regular training. Oh, and you won't be paid for any of this. Would you take the job?

    This job might not necessarily appeal to everyone, but if this sounds like an opportunity you'd eagerly accept，then you'd fit right in with Western Australia's 26,000 emergency service volunteers. The emergency services aren't the only industry benefiting from volunteers. Across both Australia and America, between a quarter and half of the population volunteer each year in areas including education, sports, health, religion, and social services.

    What motivates people to volunteer? Yes, volunteers don't get paid. But it doesn't mean people don't get benefits from volunteering. Indeed, research shows there are significant mental health benefits coming with volunteering. It can be a means to make new friends, build new skills or try things out of your comfort zone. It can also be a means to help loved ones. A case is someone close to me who recently lost her husband to a disease. When her husband was admitted to a nursing facility, she decided to volunteer for the patient advocacy committee. She found great support and felt she could make a difference in the lives of the patients. After her husband's passing, she decided to continue volunteering for the committee not only as a way to show gratitude for the great care her husband received but also because she made friends there. She found a way to put her career skills to use for the common good and keep active after retirement.

    There are countless ways to volunteer. No matter how you do it, it is definitely worth every minute you put into it.

Deep below the ground, radioactive elements break up water molecules(分子), producing substances that can fuel subsurface life. This process, known as radiolysis(辐射分解),has supported bacteria in tiny cracks filled with water on Earth for millions to billions of years. Now a study published in Astrobiology shows that radiolysis may have supported life in the Martian subsurface. 

Dust storms, rays in the universe and solar winds ruin the Red Planet's surface. But below, some life might find shelter. "The best survival habitat on Mars is the subsurface," said Jesse Tarnas, a planetary scientist at NASA, Examining the Martian underground could help scientists learn whether life existed there. And the best subsurface samples available today are Martian meteorites(陨石) that have crash-landed on Earth.

Tarnas and his colleague looked at the minerals on the Martian surface and how many radioactive elements there were, using satellite and rover data, They used computers to simulate(模拟) radiolysis to see how efficiently the process would have generated life-supporting hydrogen gas and other chemical substances. They reported that if water was present, radiolysis could have supported life for billions of years and perhaps still could today. 

Scientists had previously studied Mars radiolysis, but this marked the first estimate using Martian rocks to see how habitable Mars underground might be. Tarnas and his colleagues also evaluated the potential richness of life in Martian underground.They found that up to a million bacteria could exist.in just one kilogram of rock, The most habitable seemed to be the southern highlands of Mars, which is the most ancient area on Mars, according to Tarnas.

"Underground life would require water and it remains unknown if groundwater exists on the planet," says Lujendra Ojha, a planetary scientist at Rutgers University. Determining whether the Martian, subsurface contains water. will be an important next step, but this investigation helps to motivate that search, Ojha says, "Where there is groundwater, there could be life."
