When another old cave is discovered in the south of France, it is not usually news. Rather, it is an ordinary event. Such discoveries are so frequent these days that hardly anybody pays heed to them. However, when the Lascaux cave complex was discovered in 1940, the world was amazed. Painted directly on its walls were hundreds of scenes showing how people lived thousands of years ago. The scenes show people hunting animals, such as bison or wild cats. Other images depict birds and, most noticeably, horses, which appear in more than 300 wall images, by far outnumbering all other animals.

    Early artists drawing these animals achieved a monumental and difficult task. They did not limit themselves to the easily accessible walls but carried their painting materials to spaces that required climbing steep walls or going on hands and knees into narrow passages in the Lascaux complex.

    Unfortunately, the paintings have been exposed to the destructive action of water and temperature changes, which easily wear the images away. Because the Lascaux caves have many entrances, air movement has also damaged the images inside.

    Although they are not out in the open air, where natural light would have destroyed them long ago, many of the images have deteriorated and are hardly recognizable. To prevent further damage, the site was closed to tourists in 1963, 23 years after it was discovered.

    When was the last time someone unexpectedly did something nice for you? Not someone you knew, but a total stranger? It's happened to me a few times, but two instances really stand out.

    A few years ago, I was dining in a restaurant with a friend who kept talking about himself completely not aware of the fact that I was sitting there in misery. It wasn't my friend's talks that made me suffer. I was recovering from a broken heart, and just sitting down to dinner reminded me of my last relationship. I could have burst into tears right there at the table.

    When we picked up the check, the waitress said “ Your meal was already paid for .” My friend and I didn't have a clue how it happened. Then I remembered a man I saw out of the corner of my eye. He was dressed in mostly white, sat down at the bar, had a beer, and stayed for maybe ten minutes . The waitress said ,”Yes , the gentleman in white paid for you .” It felt like an angel was saying “I see you , honey. It's going to be okay.”

    Just last year, I was running a half-marathon. With just 1 mile to go, I was out of gas. Runners call it “hitting the wall”. I thought I couldn't move another inch. Out of nowhere, a stranger came up to me and said, “What's your name, sweetie? Jennifer? Okay, Jennifer, let's go! Come on! It's just around the corner! You can do it!” And he ran with me until I picked up my pace. I found him at the finish line to thank him for the encouragement only to learn he wasn't even supposed to be in the race that day.

    I still shake my head when I think of these momentary angels that came to me at my point of need. Do you have any experiences like these?

    A survey by an international temporary service agency found that U. S. managers believe that people with a sense of humour do better at their jobs, compared with those who have little or no sense of humour. In fact, about 96 percent of those surveyed said people with a sense of humour do better.

    The survey went on to point out that the results suggest that a sense of humour may help light-hearted employees keep their jobs during tough times. And, what's more, it may push them up the corporate ladder past their humourless colleagues. Why? It seems that those with a sense of humour are better communicators and better team players.

    Studies have shown that happy workers are more productive. In fact, a researcher at California State University found that humour could help the employees to release tension.

    Research done by psychologist Dr. Ashton Trice at Mary Baldwin College in Virginia showed that humour helps us think. When people feel stuck on important projects, they tend to feel angry or depressed.  According to Dr. Trice's research, taking time out to laugh can help us to get rid of negative feelings and allow us to return to a task or move on to another project unaffected by past defeat.

    If humour is really this important, then why don't we use it more often on the job? Most likely, the main reason is that many people are unaware of the positive effects of humour in the workplace. However, it is important to realize that some humour is not suitable for the workplace, and that it is often used at wrong times.

    Become a Volunteer and Make a Difference

    The First Tee, as an outstanding youth development organization, is always searching for good people that want to volunteer at one of our many Pittsburgh area locations.

    We're Looking for You!

    Nationwide, we currently have more than 3,700 coaches signed up with The First Tee as well as volunteers. But you don't have to be a golf professional or even a good golfer. With The First Tee Coach Program, we provide the training you need.

    Developed with input from leading experts in the field of positive youth development, our program focuses on making participants stronger and more confident through decision-making and exploring options, inspiring the golfers of tomorrow to look to the future, set goals, and unlock their potential.

    We also need more volunteers to make The First Tee possible. Opportunities include:

    Assistant Coach: assist in our weekly golf clinics. All that we request is that you make a 7-week commitment (one day per week), for 2 hours each week. Each clinic is led by one of our trained staff members who creates a written lesson plan for our volunteers to follow.

    Database Manager: input data entry of participants, volunteers, and community relation records and update chapter information for Home Office and community relations. The database manager is expected to update the data a minimum of every other week.

    Equipment Manager: organize and sort donated equipment, get rid of unfit equipment, and arrange equipment for distribution to participants at least once a week.

    Greeter: register participants, hand information to parents, greet visitors, answer phone and provide general program information.

    Do you ever wonder why trees begin to bud (发芽) earlier in some cities? Scientists finally found the answer but it's not very pleasant. New science suggests a relationship between light pollution and the timing when trees produce buds, which signals the arrival of the spring season.

    Light pollution is defined by the Lighting Research Center as the unwanted consequence of outdoor lighting such as street lights. Excessive (过多的) man-made light at night results in disturbed natural cycles, and also prevents the observation of stars and planets at night. But its effect on the environment goes beyond that.

    By studying some trees, researchers found out that trees that are more exposed to artificial lighting at night bud up to 7.5 days earlier than those at the natural nighttime setting. And they found out that light had a more significant effect than temperature when the buds came out. The early budding may cause problems for insects, which feed on leaves, and the birds which then feed on them in turn. Professor Richard, who helped lead the research, explained that more than the budding of trees, the study implies the danger to the balance of the ecosystem. “At the moment, caterpillars (毛毛虫) are timed to hatch to make the most of the opportunities to feed on freshly budded leaves, and birds hatch in time to feed on the young caterpillar,” he said.

    Migratory (迁徙的) birds are also negatively affected by light pollution. The glare might confuse them and make them lose their flying sense. The phenomenon might explain why some birds accidentally knock into buildings.

    Such results stress the need to pursue studies that aim to measure the effect of light pollution. If the issue were left to continue, it is estimated that by 2100, spring would begin almost a full month earlier than it does today.

    In this Pennsylvania city, Pittsburgh is shrinking but getting wealthier. Since 2000, its population has declined by 95,000 while its income per capita (人均) has shot up 24 percent. The trend is taking hold in many other cities, like Buffalo in New York, Providence in Rhode Island and New Orleans.

    Some of these areas have created more high-paying jobs in energy, health care or education. Others have managed to reshape their producing industry for a new economy. Higher-paying jobs have a greater effect because they create demand for additional services. "The story in Pittsburgh is very positive, and other areas are looking at it as an example of the transformation that might be possible," said Guhan Venkatu, who wrote an economic history of the area called “Rust and Renewal" for the Federal Reserve Bank of Cleveland.

    Carnegie Mellon University and the University of Pittsburgh have helped bring tech jobs and innovation(革新) to the area by sponsoring tech centers that help graduates start companies without moving to Silicon Valley or San Francisco. This has helped keep Pittsburgh's educated young population growing even as the entire population in the city has dropped.

    Pittsburgh has more STEM (science, technology, engineering and math) jobs than other shrinking cities, about 80, 000 or 7% of all jobs. STEM jobs add productivity and income growth to the area. Manufacturers of high-tech medical equipment in the Pittsburgh area also have doubled employment in the last 10 years.

    However, some experts question whether growing income per capita can really make up for a declining population. According to Patrick Adler, a researcher at the University of Toronto, population loss does matter if it means lower-skilled workers have fled because of a lack of opportunity. What's more, high-paying jobs in education and health care can disappear if the population declines too greatly. So it'd be wise to find ways to increase the population.
