Article: Why are we addicted to upgrades? According to Donald Norman, American author of the book The Design of Everyday Things, "planned obsolescence" is the trick behind the upgrading culture of today's consumer electronics industry. The New York Times cited Norman last month, saying that electronics manufactures strategically release new upgrades periodically, both for hardware and software, so that customers on every level feel the need to buy the newest version. "This is an old-time trick- they're not inventing anything new," he said. Thomas Wensma, a Dutch designer, despises the "planned obsolescence" of companies, as recently reported by UK-based The Guardian. Wensma said this is a wasteful system through which companies - many of them producing personal electronics - release shoddy products simply because "they know that, in six months or a year, they'll put out a new one". But the new psychology of consumers is part of this system, as Wensma said to the newspaper: "We now want something new, something pretty, the next shiny thing." _ "It's to the damage of the consumer and the environment," as the New York Times quoted Norman. "But perhaps to the betterment of the stockholder." In its most recent fiscal year, Apple's profit margin was more than 21 percent, reported the Los Angeles Times. At Hewlett-Packard, the world's biggest PC manufacturer, it was only 7 percent. "Steven Jobs pushed the principle of 'planned obsolescence' to new heights," the newspaper commented on the company's profits and marketing strategy. "Apple's annual upgrades of its products generate sales of millions of units as owners of one year's MacBook or iPhone line up to buy the newest version, even when the changes are incremental." Peer pressure As to Li Jijia, the need for upgrading his smart phone comes mainly from friends and classmates. When the majority of friends are switching to the latest devices, he worries about feeling left out. "Some apps and games require better hardware to run," said Li. "If you don't join in, you lose part of the connection to your friends."

Article: The Bronte sisters were three sisters who became famous novelists. Their lives and works are connected with the lonely moors of Yorkshire, England, where they lived. Patrick Bronte, the sisters' father, was a poor Irishman who became the parish clergyman of the small, isolated town of Haworth, Yorkshire. Bronte was somewhat strange and tended to be strict. His wife died in 1821 and her sister brought up the family out of duty, but with little love or understanding. The sisters went to several boarding schools where they received a better education than usual for girls at that time, but in a bad atmosphere. Few jobs were available for women at that time, and the Bronte sisters, except for occasional jobs as governesses or schoolteachers, lived their entire lives at home. They were shy, poor, and lonely, and occupied themselves with music, drawing, reading and ---above all---writing. Their isolation led to the early development of their imaginations. In 1846, under the male pen names of Currer, Ellis, and Acton Bell, the sisters published a joint volume of poems.Although only two copies were sold, all three sisters soon had their first novels published. Charlotte Bronte's most famous novel Jane Eyre (1847) is largely _ . Through the heroine, Charlotte relived her hated boarding school life and her experiences as a governess in a large house. Rochester, the hero and master of the house, is fictional. Jane Eyre was enormously successful, but many readers were shocked that Rochester, who tried to make Jane his mistress, should be rewarded by marrying her. Some readers were also shocked because Jane wanted to be regarded as a thinking and independent person, rather than as a weak female. Charlotte Bronte wrote three other novels. The first one, The Professor, was not published until 1857, after her death. Shirley (1849) is set among the labour riots of the early 1800s. Villette (1853) the most popular of the three, is based on Charlotte's unhappy experiences as a governess in Brussels.

Article: They said highly anxious rats which were kept had very low levels of a brain chemical called fibroblast growth factor 2 or FGF2, compared with rats that were more relaxed. But when they improved the anxious rats' living conditions -- giving them new toys to explore and a bigger cage to live in -- levels of this brain chemical increased and they became less anxious. "The levels of this brain chemical increased in response to the experiences that the rats were exposed to. It also decreased their anxiety". Javier Perez of the University of Michigan said in a telephone interview. "It made them behave the same way as the rats that were relaxed", he said. In a former study of people who were severely depressed before they died, the team found the gene that makes FGF2 was producing very low levels of the growth factor, which is known primarily for organizing the brain during development and repairing it after injury. Perez thinks the brain chemical may be a marker for genetic vulnerability to anxiety and depression. But it can also respond to changes in the environment in a positive way, possibly by preserving new brain cells. While both the calm and anxious rats produced the same number of new brain cells, these cells were less likely to survive in the high-anxiety rats, the team found. Giving the rats better living conditions or injecting them with FGF2 helped improve cell survival. "This discovery may pave the way for new, more specific treatments for anxiety that will not be based on sedation , but will instead fight the real cause of the disease," Dr. Pier Vincenzo Piazza from France said in a statement.
