I began cycling in 2004 when I was a poor student. It was dangerous, sure, but cycling is the fastest, cheapest point-to-point form of transport in Melbourne. I own a car now, but that's just for transporting the baby or groceries.

    I hate driving. So it's been quite encouraging watching the growth in cyclist numbers over the past decade. It is estimated 10,000-plus cyclists enter the CBD (Central Business District) each day, taking pressure off public transport. But as more people take to cycling as a mode of transport, the number of cyclists seriously injured or killed keeps climbing. And that is a sign that our infrastructure (基础设施) is still not good enough.

    Melbourne was once a dream for cyclists-flat, long, wide roads, with plenty of paths along rivers. Now, cycling can be deadly, with roads dominated by cars. I have a friend who broke her back and was lucky to escape paralysis, and others with broken bones. In my time riding, I've been forced off the road by a truck, cut off by four-wheel drives, and told to get off the road.

    These things don't exactly happen to trams and buses, those other slowcoaches on Melbourne's roads. No—drivers reserve a particular savagery (残暴行为) for cyclists. And that's a sign of exactly one thing: inadequate infrastructure.

    We shouldn't need to be taught how to coexist in the same narrow space. Drivers and cyclists should be kept apart. The present debate over how to minimize “dooring” is a distraction.

    Dooring is not a legal problem. You cannot legislate (制定法律) it away. Designing bike paths so riders are channelled between moving cars and parked cars is deadly. All it takes is one daydreaming driver to fling open the door and you are gone. That's what happened to the young university student James Cross.

    This year, there are to be new anti-dooring lanes (车道) built on Glenferrie Road, Hawthorn, where Cross died in 2010. But these lanes are not safe. Cyclists must still pass between two rows of cars.

Prague VS Vienna: Which One to Visit?

    Prague and Vienna are both wonderful and exciting cities with modern cosmopolitanism and ancient history and culture. But if you've got a European vacation planned and are trying to decide which one of these amazing cities to visit, it can be daunting(困难)for sure.

    Sightseeing

    While both cities are rich in sightseeing adventures, Prague is definitely more beautiful as a city. You can walk along the Danube River for breathtaking views, sit in one of the many cafes that dot the urban landscape, and breathe in the amazing architecture  both old and modern that makes up this Central European metropolis(都市).Vienna is a hotbed of history, home to such great sites such as The Hofburg, Schonbrunn Palace and Gardens, and St. Stephen' S Cathedral.

    Shopping

    You most likely didn't travel all the way to Europe just to go shopping. But, if you happen to be a shopaholic, Vienna is definitely better. But be warned: fine goods you buy in Vienna will sometimes be three times more expensive than what they are in the United States or Canada.

    Cuisine

    When it comes to great dining, both cities are equally fascinating. Austrians are known for their love of sweets and pastries(糕点), which is reflected in the many bakeries, cafés, and restaurants scattered around Vienna. Some restaurants in either city offer local cuisine, though you're more likely to be eating a combination of Western European or even Americanized food. Bear in mind that Prague(being that it is in Central Europe)will be far less pricey than Vienna.

    Culture

    What do you hope to see on your trip? Palaces? Medieval Cathedrals? The Opera? How about museums? If you do happen to visit both cities, you'll find that culture equally as enriching. However, Vienna has more world—class museums which display the rich history of the area.

    The search engine Google celebrated on Thursday the 110th birthday of the first Native American woman engineer. Google honored Mary Ross with a special Google Doodle on its homepage.

    Ross was born on August 9, 1908, in the state of Oklahoma. She was the great-granddaughter of John Ross, the longest—serving chief of the Cherokee Nation. Her work is considered important to the early stages of the age of space travel.

    Ross showed special abilities in math and science from an early age. As a student, she developed an interest in aviation, or the practice of flying aircraft. She went on to earn a master's degree in mathematics from Colorado State Teachers College, now called the University of Northern Colorado.

    During World War II, Ross began working for the Lockheed Aircraft Corporation as a mathematician. She earned a special certification in the field from the University of California in1949.Ross was later chosen to join Lockheed's top—secret Skunk Works team that worked on aircraft designs. The name refers to a group that is permitted to work independently on advanced projects. She was the only female engineer among the team's 40 members.

    Early on, she researched defense systems. By the late 1950s, her work centered on satellites and a series of space rockets called Agenda. The rockets were extremely important in the 1960s during the Apollo moon program.

    Ross also helped develop early design ideas for space travel between planets, including flyby space flights to study Venus and Mars. Ross retired from Lockheed in 1973.But she continued to give talks at high schools and colleges to encourage more women and Native Americans to study engineering. She died in 2008, a few months before her 100th birthday.

    Many celebrated Ross' life on social media. Twitter user Aaron Perez, for example, wrote: “Mary Ross was an engineer who pioneered in the field of satellites. I never would have known if it wasn't for the doodle. Women engineers deserve more recognition.”

    Chrysanthemums (菊花) are to the fall what tulips are to the spring.

    In ancient China chrysanthemums (or 'mums' for short) were first planted thousands of years ago. People chose the chrysanthemum as their Flower for October a symbol of the rest and ease that followed the season's final harvest. Then they symbolized a scholar in retirement (隐居) and were one of the four noble(高贵的) plants along with bamboo, the plum flower(梅) and orchid(兰).

    The Japanese hold the chrysanthemum as a symbol of the sun. They consider the orderly unfolding of its petals(花瓣) to be a symbol of perfection. They also think that a single chrysanthemum petal placed in the bottom of a wine glass encourages a long and healthy life. The Japanese even have a National Chrysanthemum Day on September 9 known as the Festival of Happiness.

    In the United States during colonial times its popularity grew such that mums now reign as "Queen of the Fall Flowers." Mums remain the most widely grown pot plant in the country and the largest commercially produced flowers. Chrysanthemums generally represent cheerfulness and rest. So they are welcomed throughout the British Isles and North America for any occasion such as football games and parties.

    In other countries such as Italy Belgium and Austria however their association with the dead makes chrysanthemums acceptable only for funerals and graves.

More than 400 athletes across a variety of sports, ages and levels of experience were questioned for the study by sports psychology experts from Staffordshire University and Manchester Metropolitan University. The findings reveal that athletes' belief systems—specifically irrational（非理性）beliefs—are related to poorer self-confidence, and in turn, greater competitive anxiety and depressive symptoms.

"Phrases that reflect self-depreciating（贬低）beliefs such as ‘If I lose, I'm a failure' or ‘If I face setbacks, it shows how stupid I am' are warning signs," said the authors. Paul Mansell, Lecturer in Sport and Exercise Psychology at Staffordshire University, said, "Despite the psychological benefits of physical activity, studies frequently report poor mental health in athletes, which may be exacerbated by adversities, such as injury, de-selection, and performance pressure. We investigated athletes' beliefs, how they view stress, their levels of self-confidence and put all this data together to work out what might predict psychological well-being. We found irrational beliefs to be a core reason for symptoms of poor mental health in athletes."

This is the first known study that has examined irrational beliefs, self-confidence, and the psychological well-being of athletes all together. Irrational beliefs are extreme, rigid, and illogical ideas that people hold. For example, a person might believe that they "must" get what they want, or that just because they have failed, they are a "complete failure".

"We can all work to help athletes develop mindsets that help them deal with the challenges of sport and life. By encouraging rational and logical beliefs about performance, we can help athletes to stay healthy amidst the high demands of competitive sport," said Paul Mansell.

The author s propose Rational Emotive Behavior Therapy（REBT）as an effective tool for protecting self-confidence. REBT helps athletes to challenge these self-depreciating beliefs and develop beliefs that are more helpful and healthy. For example, rather than believe "I am a failure if I fail", this might be countered with "Failing is not ideal, but it does not mean that I am a failure".
