“A room without books is like a body without a soul,” observed the Roman philosopher, Cicero. It can also be a sign of financial problems to come. New research has uncovered a strong connection between the earning of adults and whether they grew up surrounded by books as children.

    Three economists at the University of Padua—Giorgio Brunello, Guglielmo Weber and Christoph Weiss—studied 6000 men born in nine European countries and concluded that children with access to books could expect to earn more money than those who grew up with few or no books.

    They studied the period from 1920 to 1956, when school reforms saw the minimum school leaving age raised across Europe. They booked at whether, at the age of 10, a child lived in a house with fewer than 10 books, a shelf of books, a bookcase with up to 100 books, two bookcases, or more than two bookcases.

    Over the period studied, the research, published in The Economic Journal, found that an additional year of education increased a man's average lifetime earnings by 9%. Men brought up in houses with less than a shelf of books earned only 5% more as a result of the extra year's education, compared with 21% more for those who had access to a lot of books. And those who had access to books were more likely to move to the better-earning opportunities in cities than those without books. The men's first job was also much more likely to be a white-collar job.

    The economists offer a number of theories for the results. “Perhaps books matter because they encourage children to read more and reading can have positive effects on school performance,” they said.

    The number of books in children's homes can effectively predict their cognitive(认知的) test scores. This may indicate a home that encourages cognitive skills, which are important for economic success in life.

    Why is pink or purple a color for girls and blue or brown for boys?

The answer depends largely on cultural values as well as personal experiences. To the Egyptians, green was a color that represented the hope and joy of spring, while for Muslims, it means heaven. Red is a symbol of good luck in many cultures. In China, children are given money in a red envelope to bring good fortune in the New Year. For many nations, blue is a symbol of protection and religious beliefs. Greek people often wear a blue necklace hoping to protect themselves against evils (灾祸).

    People's choice of colors is also influenced by their bodies' reactions (反应) toward them. Green is said to be the most restful color. It has the ability to reduce pain and relax people both mentally and physically. People who work in green environment have been found to have fewer stomachaches.

Red can cause a person's blood pressure to rise and increase people's appetites (食欲). Many decorators will include different shades of red in the restaurant. Similarly, many commercial (商业的)websites will have a red “Buy Now” button because red is a color that easily catches a person's eye.

    Blue is another calming color. Unlike red, blue can cause people to lose appetite. So if you want to eat less, some suggest that eating from blue plates can help.

    The next time you are deciding on what to wear or what color to decorate your room, think about the color carefully.

    John J. Lennon, who's currently serving a 28-year life sentence for drug dealing and a murder he committed in 2001. He is one of 23 out of 2,300 inmates(监犯)participating in an education program, and he advocates greater access to education in prison through TV. Currently, he says the TV is used as “an inability tool; it's a tool to keep us entertained cells.” But he suggests that prison TVs should stream online courses instead of movies.

    “If inmates had the chance to watch an online course then they might say, ‘Hey, look what's on Channel 3; it's an interesting lecture from a professor of philosophy.' Believe it or not, people will tune in, and after the lecture they're going to go on their gates, hang on their bars, and they're going to talk about it.”

    Education, he says, also makes prison a safer place. “If I'm working on a paper banging away(砰砰响个不停)on my typewriter, I have other things on my mind. I'm not fighting in the prison yard.” Most prison administrators support that view. “They understand it makes prison a safer place if you have a group of guys with their eyes on the prize who are trying to change themselves.”

    John J. Lennon arrived at Attica in 2004 with a 9th grade education, but in May will graduate with a two-year associate degree. Attica creative writing workshops have changed his life.

    “I came into prison looking up to gangsters(匪徒), now I look up to scholars and intellectuals like Doran Larson, Tim Golden, all these Pulitzer-winning journalists. Education has changed the lens(镜头)through which I view the world. I don't look up to gangsters anymore. I think it's a horrible lifestyle.”

    Hamilton College professor Doran Larson has been teaching creative writing workshops at Attica since 2006. He says the demand for education from inmates is enormous and that it's “almost impossible to create a program large enough to satisfy the desire which pushes against the public perception(认识)that such people inside aren't interested in education.”

    Thoughts on prison education have changed over the years. Until 1973, there was a period of rehabilitation(改造)in American prisons. Even after that year, college degree programs were available for inmates nationwide until 1994, when the country's movement to get tough on crime made prisoners not qualified for Pell fund aid. “We have moved to a punishment mentality(心态),” Larson says. No one cared about these people “as long as they are kept from the outside.”

    Larson argues that inmates want to become productive members of society. The prison population is “a huge untapped resource, both commercial and intellectual. And right now there is far from enough being done to tap into skills which can get them off the public dole(失业救济金)and turn them into taxpayers.”

    Sydney Trains is one of the most economical, reliable and convenient ways to travel throughout Sydney and its surrounds.

    Our network, the NSW Trains Intercity, covers suburban Sydney and extends to the Hunter, Central Coast, Blue Mountains, Southern Highlands and South Coast regions.

    The network is made up of several colour-coded lines. Trains from different lines can share the same platform, so check display screen and listen to announcements.

    Ticket prices are generally based on the distance traveled. You can visit Transportnsw.Info for details.

    Getting to the City

    In Sydney, if you're near a train station, you're on your way to the city. Every rail line leads directly or indirectly to the City Circle. It's the loop around the central business district of Sydney. Most City stations are underground so look out for the sign on street level.

    Automatic ticket gates

    Large stations have automatic gates for entry to, and exit from, the station. If you have an Opal card or a ticket which has a magnetic stripe (磁条) you must use the automatic gates. You may use the wide gate for wheelchair, pram or luggage access. Station staff will assist you.

    Night Ride buses

    Most trains do not operate between midnight and 4:00 a.m. For your convenience a special Night Ride bus service is available between these hours on most Sydney suburban lines.

    Track work

    In order for the tracks to the maintained, we sometimes have to replace train with buses, particularly at weekends. Please check the track work section for the latest service changes on your line.

    Many people traveled to Las Vegas, Nevada last week for the 50th Consumer Electronics Show, or CES. The show is said to have the largest collection of new electronic devices in the world.

    The show had many examples of “smart home” devices. “Smart home” technology is designed to make life easier for people by letting computers control many things inside our homes. One such device actually begins working outside the home, when someone arrives and rings the doorbell.

    “When someone comes to your front door and rings the doorbell, the light can turn on immediately. I get a notification when I'm halfway around the world that someone came, and I can start talking to the person who's at my front door, and I can say, 'Oh, here let me let you in,' I can unlock the door for them very easily.” Said Vivint, a smart home service provider.

    One electronics maker launched a device that lets people see and interact with their animals when they are away. The device, from Petcube, lets you remotely watch and talk to your pet through a personal device, according to a company official. It can even give the pet a treat—if you approve and order it.

    For heating or cooling, there is a smart thermostat. This device can also send you a message if a big storm causes leaks of flooding. “We're trying to catch it with just a few drips before it becomes a real big problem,” said Mike Sale of iDevices.

    A concern for many homeowners is the possibility that someone else might find a way to attack these smart home devices. An official from Vivint said his company is sure that only owners of the home can gain use of information on the devices. Warren Katz from iDevices said his company employs engineers from the defense industry to help prevent hacking.

    Standing desks have become common across Silicon Valley, offering health benefits to those willing to work on their feet. However, due to their high price, they have failed to catch on until now. Recently, Ikea has brought out Bekant convertible（可变换的） standing desk that can become a normal desk at the touch of a button. The $500 adjustable desk can transform from a standard desk to a standing one, and Ikea hopes it could make the standing desk mainstream.

    Experts say that changing from a seated to a standing desk can improve productivity. Similar desks have become a common sight at tech firms such as Google, where some employees have even installed treadmill (跑步机) and bicycle desks.

    The desk is not the first “convertible” on the market. As early as 2013, Stir Kinect brought out an adjustable desk. The $3,890 Stir Kinect desk has a motor to raise and lower itself, changing it into a standing desk or a traditional desk. The desk can even be programmed to move up and down slightly, making it appear to take a gentle breath to remind the user to change their positions. To move between sitting and standing positions, owners simply double tap on the screen. The desk can learn the user's preferences over time and suggest the best seating position.

    The Stir Kinect desk was created by a team of ex-Apple and Disney engineers. It has a built-in touch screen to control and track movement, and can tell users exactly how many calories they burn by standing during their working day. It also has devices containing power points and USB ports for charging phones, to keep cables hidden.

    “Ikea's height-adjustable desk is great for opening up the lower end of the market, '' said JP Labrosse, founder and CEO of Stir.
