question:
Article: What's in name? Well, apparently, our general happiness. Psychologists say that what we are called has a direct connection with our happiness. Those called Judy and Joshua are the happiest, while Lynn or Ben is likely to be the unhappiest, according to research. Psychologist Dr David Holmes found that this can cause the association that others make with the name. Hearing the name Judy may make them think of actress Judi Dench or TV presenter Judy Finnigan, and people who are considered good-natured and happy. On the other hand, people think Paulines are unhappy because of the character Pauline Fowler from the TV programme East Enders. The research claims that this association influences the person with the name and so their personality is shaped to fit in. Dr David Holmes said, "This also has some relation with the original meaning of the name, for example, the original meaning of Judy is 'praised'." Certain names also work well in certain aspects of life. In the workplace Richard and Judy are the happiest, while those called Ruth and Carly are the happiest in relationships. At the other end of the scale the unhappiest workers are Stuart and Liz, with the unhappiest in relationships being Frank and Harriet. Dr Holmes said, "The relation we have with certain names, particularly important namesakes , also shapes how we see ourselves and so may have an effect on our confidence. Names are like product brands in having a powerful effect on attitudes and should therefore be chosen with care." "Other names are connected with being brave, outgoing or serious. Therefore, many celebrities change their names to ones which reflect these characteristic. This, in turn, influences parents when they choose names for their babies," said Dr Holmes, "while names connected with ordinary people are rarely chosen for their babies."
Answer: The relation between names and happiness.

Article: Most people know precious gemstones by their appearances. An emerald flashes deep green, a ruby seems to hold a red fire inside, and a diamond shines like a star. It's more difficult to tell where the gem was mined, since a diamond from Australia or Arkansas may appear the same to one from the Democratic Republic of the Congo. However, recently, a team of scientists has found a way to identify a gemstone's origin. Beneath the surface of a gemstone, on the tiny level of atoms and molecules , lie clues to its origin. At this year's meeting of the Geological Society of America in Minneapolis, Catherine McManus reported on a technique that uses lasers to clarify these clues and identify a stone's homeland. McManus directs scientific research at Materialytics, in Killeen, Texas. The company is developing the technique. "With enough data, we could identify which country, which mining place, even the individual mine a gemstone comes from," McManus told Science News. Some gemstones, including many diamonds, come from war-torn countries. Sales of those "blood minerals" may encourage violent civil wars where innocent people are injured or killed. In an effort to reduce the trade in blood minerals, the U.S. government passed law in July 2010 that requires companies that sell gemstones to determine the origins of their stones. To figure out where gemstones come from, McManus and her team focus a powerful laser on a small sample of the gemstone. The technique is called laser-induced breakdown spectroscopy. Just as heat can turn ice into water or water into steam, energy from the laser changes the state of matter of the stone. The laser changes a miniscule part of the gemstone into plasma, a gas state of matter in which tiny particles called electrons separate from atoms. The plasma, which is superhot, produces a light pattern. (The science of analyzing this kind of light pattern is called spectroscopy.) Different elements produce different patterns, but McManus and her team say that gemstones from the same area produce similar patterns. Materialytics has already collected patterns from thousands of gemstones, including more than 200 from diamonds. They can compare the light pattern from an unknown gemstone to patterns they do know and look for a match. The light pattern acts like a signature, telling the researchers the origin of the gemstone. In a small test, the laser technique correctly identified the origins of 95 out of every 100 diamonds. For gemstones like emeralds and rubies, the technique proved successful for 98 out of every 100 stones. The scientists need to collect and analyze more samples, including those from war-torn countries, before the tool is ready for commercial use. Scientists like Barbara Dutrow, a mineralogist from Louisiana State University in Baton Rouge, find the technique exciting. "This is a basic new tool that could provide a better fingerprint of a material from a particular locality," she told Science News.
