During the late years of the Qi Dynasty(221-206BC), Xiang Yu led a rebellion. After crossing the Zhang River, Xiang Yu ordered his men to sink all their boats and break their cooking pots. He issued each soldier three days' rations and warned them that there was no way to retreat; the only thing they could do to survive was to advance and fight. After mine fierce battles, the Qin army was finally defeated.

New Zealand

In the beginning was the word -- yes, but where exactly? Last year, Quentin Atkinson, a cultural anthropologist at Auckland University in New Zealand, proposed that the cradle of language could be localized in the southwest of Africa. The report, which appeared in Science, was seized upon by the media and caused something of a sensation. Now however, LMU linguist Michael Cysouw has published a commentary in Science which argues that this neat "Out-of-Africa" hypothesis for the origin of language is not adequately supported by the data presented. The search for the site of origin of language remains very much alive. Atkinson based his claim on a comparative analysis of the numbers of phonemes found in about 500 present-day languages. Phonemes are the most basic sound units -- consonants, vowels and tones -- that form the basis of semantic differentiation in all languages. The number of phonemes used in natural languages varies widely. Atkinson, who is a biologist and psychologist by training, found that the highest levels of phoneme diversity occurred in languages spoken in southwestern Africa. Furthermore, according to his statistical analysis, the size of the phoneme inventory in a language tends to decrease with distance from this hotspot.
prom dresses 2012
To interpret this finding Atkinson invoked a parallel from population genetics. Biologists have observed an analogous effect, insofar as human genetic diversity is found to decrease with distance from Africa, where our species originated. This is attributed to the so-called founder effect. As people migrated from the continent and small groups continued to disperse, each inevitably came to represent an ever-shrinking fraction of the total genetic diversity present in the African population as a whole.

So does such a founder effect play a similarly significant effect in the dispersal and differentiation of languages? Michael Cysouw regards Atkinson's finding as "artefactual." Cysouw, whose work is funded by one of the Starting Grants awarded by the European Research Council (ERC), heads a research group that studies quantitative comparative linguistics in LMU's Faculty of Languages and Literatures. He says he has no objection in principle to the use of methods borrowed from other disciplines to tackle questions in linguistics, but that problems arise from their inappropriate application.
prom dresses on sale
For example, he finds that if Atkinson's method is employed to examine other aspects of language, such as the construction of subordinate clauses or the use of the passive mood, the results "do not point in the same direction." Indeed, in their article in Science, Cysouw and his coauthors Steven Moran (LMU) and Dan Dediu of the Max Planck Institute for Psycholinguistics in Nijmegen show that, depending on the features considered, Atkinson's method places the site of origin of language in eastern Africa or the Caucasus or somewhere else entirely. As Cysouw points out, linguists have long sought to throw light on the origin of language by analyzing patterns of language distribution. The problem is that such relationships can be reliably traced only as far back as about 10,000 years before the present.

Avon

Federal prosecutors have presented evidence to a grand jury against U.S. executives of cosmetics company Avon Products, in a case that probes whether those executives broke foreign bribery laws, the Wall Street Journal said.
In 2008, Avon said that it had started an internal investigation into whether it had violated the Foreign Corrupt Practices Act, which bars U.S.-linked companies from paying bribes to officials of foreign governments. evening dresses with sleeves
U.S. authorities are studying a 2005 internal audit report by the company that concluded Avon employees in China may have been bribing officials in violation of the Foreign Corrupt Practices Act, the Journal said, citing three people familiar with the matter.
The federal authorities are probing whether current or former executives ignored the audit's findings or actively took steps to conceal the problems, both potential offences, the newspaper said.
"We're not aware that a federal grand jury is investigating this,'' an Avon spokeswoman told the Journal. black evening dresses
She declined to confirm to the paper whether there had been an audit in 2005 and declined to discuss how executives handled any such audit.
In January, Avon's former CFO Charles Cramb left the company amidst a probe initiated by the U.S. Securities and Exchange Commission.

President Obama

President Obama, a noted passionate hoops fan, has been swept up in the Knicks rookie Jeremy Lin’s remarkable run, his Press Secretary Jay Carney said.
"The President is an avid sports fan and particularly avid basketball fan and we were speaking about Jeremy Lin on Marine One as we flew here to Andrews Air Force Base this morning,” Carney told reporters en route to a campaign event in Milwaukee.
“It's just a great story and the President was saying as much this morning,” Carney said. “Obviously terrific for the New York Knicks but it's the kind of sports story that transcends the sport itself." plus size evening dresses
Though Obama is a Chicago Bulls booster, the First Fan made certain to catch the highlights of Lin’s buzzer-beating three-pointer to best the Toronto Raptors Tuesday night, Carney said
"It's a great story and yes, he's very impressed and fully up to speed,” Carney said. “I know he's watched Lin play already.”
The Knicks do not have another game in Washington this season, but if the President wants to catch Lin in person, he can travel to his hometown to watch the Knicks play in Chicago on March 12. formal evening dresses

Mr. Eastern (二)

After she left, people went to the palace to show the emperor the decree which reads "The capital city is in trouble. Fire burns on the palace, and fire from Heaven burns all night long on the 15th." The emperor of Han Dynasty was very shocked. He called and asked Mr. Eastern for advice. After pondering for a while, Mr. Eastern said, "I heard that the God of Fire likes to eat Tang-Yuan (Sweet dumpling). Does Yuan-Xiao often cook Tang-Yuan for you? On the 15th lunar day, let Yuan-Xiao make Tang-Yuan. Your Majesty will take charge of the worshipping ceremony and you will give an order to every house to prepare Tang-Yuan to worship the God of Fire at the same time. Also, deliver another order to ask every house in the city to hang red lantern and explode fire crackers. cheap prom dresses 2012 Lastly, everyone in the palace and people outside the city should carry their lanterns on the street to watch the lantern decoration and fireworks. If everything goes this way, the Jade Emperor would be deceived.Then everyone can avoid the fire accident."
The emperor happily followed the plan. Lanterns were everywhere in the capital city on the night of the 15th lunar day. People were walking on the street. Fire crackers kept making lots of noise. It looked like the entire city was on fire. Yuan-Xiao's parents went into the palace to watch the lantern decorations, and Yuan-Xiao made a big lantern and wrote her name on the lantern. They happily reunited together after her parents called her name. Everybody was safe during the night. The emperor of Han Dynasty had a new order that people should do the same thing every year. Since Yuan-Xiao cooked the best Tan-Yuan, people called the day Yuan-Xiao Festival. purple prom dresses

Mr. Eastern (一)

There are many stories on how this festival was created. One other story is about a maid. In the Han Dynasty, Mr. Eastern was a favorite advisor of the emperor. One winter day, he went to the garden and heard a little girl crying and getting ready to jump into a well to commit suicide. Mr. Eastern stopped her and asked why. She said she was a maid in the emperor's palace and her name was Yuan-Xiao.
She never had the chance to meet her family after she started worked at the palace. She missed them so much every 12th lunar month. If she couldn't have the chance to show her filial piety in this life, she would rather die. Mr. Eastern promised her to find a way so she could reunion with her family. Mr. Eastern left the palace and set up a fortune-telling stall on the street and disguised himself as a fortuneteller. Because of his reputation, many people asked for their fortunes. red prom dresses
But every one got the same prediction - a severe fire accident on the 15th lunar day. The rumor spread quickly. Everyone was worried about the future and asked Mr. Eastern for help. Mr. Eastern said, "On the 13th lunar day, the God of Fire will send a fairy lady in red to burn down the city. If you see a lady in red wearing green pants riding a black horse on that day, you should ask for her mercy." On that day, Yuan-Xiao pretended to be the red fairy lady. When people asked for her help, she said, "I'm the messenger of the God of Fire and came to check on the city and I'm going to set up fire on 15th. This is an order from Jade Emperor. He will watch from the heavens."I will give you a copy of the imperial decree from the God of Fire. You should go to ask your emperor to find a way out." prom dresses under 100

Lin

Lin is the first Chinese-American player in the NBA, and spent his first season with the Golden State Warriors, who signed the undrafted Harvard graduate in 2010 to fill out their roster. He saw limited minutes with the Warriors, but was cheered in arenas around the country, particularly in cities with large Asian communities, as fans came out in droves to cheer their homegrown star. prom dresses 2012
To be sure, Lin is a different kind of Asian basketball player from Yao Ming. While Yao's size put him in a somewhat self-selecting group--people north of seven feet tall can certainly do a wide range of things, but they're frequently drafted into playing basketball--Lin went from Palo Alto High School to an economics degree at Harvard, but remained committed to making it as a professional basketball player. (Yao recently enrolled at Jiaotong University's Antai Economics and Management College as his post-retirement career rolls on.)
It hasn't been an easy road for Lin. He has made several trips to the NBA's Development League, a minor league for players who show promise but need seasoning before they can compete at the highest level.
It appears to have paid off. After keying the Knicks victory over New Jersey, Lin was named the starter for the Utah game, a position he appears to have a hold on in the shot term, as Baron Davis, signed in December to play the position, lingers on the disabled list due to a herniated disk in his back.
If he can stick with the Knicks, the stars may have aligned for Lin. Knicks coach Mike D'Antoni made a name for himself with a frenetic style of play that puts particular focus on the point guard position.
After collaborating with guard Steve Nash for five successful seasons with the Phoenix Suns, D'Antoni moved to New York, where he hasn't won as much but has coached up previously middling point guards into stronger players. Chris Duhon and Raymond Felton both overcame images as limited talents under D'Antoni, blossoming into playmakers. prom dresses on sale
Lin's knack for driving to the basket and finding open teammates makes him a good fit for the D'Antoni mold, but he still has a lot of work to do before he's a proven NBA star.
The constant running in D'Antoni's offense, dubbed 'Seven Seconds or Less' for the time expected in which the team should shoot the ball, demands great fitness--Lin appeared winded at the end of the Utah game. But he'll likely get stronger the more minutes he plays, and even if Davis returns, spelling the older, recovering player could be productive for Lin, a proven good student who can learn a lot from practicing against a veteran.
And should things not work out for him in New York, he would almost certainly giver former Knick Stephon Marbury a run for his money as the biggest star in China's own basketball league. long prom dresses

McKenzie

Our "Mommy and Me" time began two years ago. My next-door neighbor and fellow mother, Christie, and I were out in our front yards, watching seven children of age 6 and under ride their bikes up and down. "I wish I could take one of my children out alone," said Christie.
Then we worked out a plan: When Christie takes one of her children out, I'll watch her other three. And when she watches two of mine, I'll take someone out. long prom dresses
The children were extremely quick to accept the idea of "Mommy and Me" time. Christie's daughter, McKenzie, went first. When she returned, the other children showered her with tons of questions. McKenzie was smiling broadly. Christie looked refreshed and happy. "She's like a different child when there's no one else around," Christie shared with me quickly. With her mother all to herself, McKenzie didn't have to make an effort to gain attention.
Just as Christie had noticed changes in McKenzie, I also discovered something different in each of my children during our alone times. For example, I am always surprised when my daughter, who is seldom close to me, holds my hand frequently. My stuttering son, Tom, doesn't stutter once during our activities since he doesn't have to struggle for a chance to speak. And the other son, Sam, who's always a follower when around other children shines as a leader during our times together. short prom dresses
The "Mommy and Me" time allows us to be simply alone and away with each child —talking, sharing, and laughing, which has been the biggest gain. Every child deserves to be an only child at least once in a while. 64. What is the text mainly about

A winter morning

It was a winter morning, just a couple of weeks before Christmas 2005. While most people were warming up their cars, Trevor, my husband, had to get up early to ride his bike four kilometers away from home to work. On arrival, he parked his bike outside the back door as he usually does. After putting in 10 hours of labor, he returned to find his bike gone. prom dresses 2012
The bike, a black Kona 18 speed, was our only transport. Trevor used it to get to work, putting in 60-hour weeks to support his young family. And the bike was also used to get groceries,saving us from having to walk long distances from where we live.
I was so sad that someone would steal our bike that I wrote to the newspaper and told them our story. Shortly after that, several people in our area offered to help. One wonderful stranger even bought a bike, then called my husband to pick it up. Once again my husband had a way to get to and from his job. It really is an honor that a complete stranger would go out of their way for someone they have never met before. prom dresses on sale
People say that a smile can be passed from one person to another, but acts of kindness from strangers are even more so. This experience has had a spreading effect in our lives because it strengthened our faith in humanity as a whole. And it has influenced us to be more mindful of ways we, too, can share with others. No matter how big or how small, an act of kindness shows that someone cares. And the results can be everlasting.

Bill Gates

Bill Gates, the billionaire Microsoft chairman without a single earned university degree, is by his success raising new doubts about the worth of the business world’s favorite academic title: the MBA (Master of Business Administration).
The MBA, a 20th-century product, always has borne the mark of lowly commerce and greed on the tree-lined campuses ruled by purer disciplines such as philosophy and literature.
But even with the recession apparently cutting into the hiring of business school graduates, about 79,000 people are expected to receive MBAs in 1993. This is nearly 16 times the number of business graduates in 1960, a testimony to the wide spread assumption that the MBA is vital for young men and women who want to run companies some day.
“If you are going into the corporate world it is still a disadvantage not to have one,” said Donald Morrison, professor of marketing and management science. “But in the last five years or so, when someone says, ‘Should I attempt to get an MBA,’ the answer a lot more is: It depends." long prom dresses
The success of Bill Gates and other non-MBAs, such as the late Sam Walton of Wal-Mart Stores Inc., has helped inspire self-conscious debates on business school campuses over the worth of a business degree and whether management skills can be taught.
The Harvard Business Review printed a lively, fictional exchange of letters to dramatize complaints about business degree holders. short prom dresses
The article called MBA hires “extremely disappointing” and said “MBAs want to move up too fast, they don’t understand politics and people, and they aren’t able to function as part of a team until their third year. But by then, they’re out looking for other jobs.”
The problem, most participants in the debate acknowledge, is that the MBA has acquired an aura of future riches and power far beyond its actual importance and usefulness.
Enrollment in business schools exploded in the 1970s and 1980s and created the assumption that no one who pursued a business career could do without one. The growth was fueled by a backlash against the anti-business values of the 1960s and by the women’s movement.
Business people who have hired or worked with MBAs say those with the degrees of ten know how to analyze systems but are not so skillful at motivating people. “They don’t get a lot of grounding in the people side of the business”, said James Shaffer, vice-president and principal of the Towers Perrin management consulting firm.

Culturally biased

Researchers who are unfamiliar with the cultural and ethnic groups they are studying must take extra precautions to shed any biases they bring with them from their own culture. For example, they must make sure they construct measures that are meaningful for each of the cultural or ethnic minority groups being studied. prom dresses 2012
In conducting research on cultural and ethnic minority issues, investigators distinguish between the emic approach and the etic approach. In the emic approach, the goal is to describe behavior in one culture or ethnic group in terms that are meaningful and important to the people in that culture or ethnic group, without regard to other cultures or ethnic groups. In the etic approach, the goal is to describe behavior so that generalizations can be made across cultures. If researchers construct a questionnaire in anemic fashion, the concern is only that the questions are meaningful to the particular culture or ethnic group being studied. If, however, the researchers construct a questionnaire in an etic fashion, they want to include questions that reflect concepts familiar to all cultures involved. prom dresses on sale
How might the emic and etic approaches be reflected in the study of family processes? In the emic approach, the researchers might choose to focus only on middle-class White families, without regard for whether the information obtained in the study can be generalized or is appropriate for ethnic minority groups. In a subsequent study, the researchers may decide to adopt an etic approach by studying not only middle-class White families, but also lower-income White families, Black American families, Spanish American families, and Asian American families. In studying ethnic minority families, the researchers would likely discover that the extended family is more frequently a support system in ethnic minority families than in White American families. If so, the emic approach would reveal a different pattern of family interaction than would the etic approach, documenting that research with middle-class White families cannot always be generalized to all ethnic groups.

Our national mythology

Ask most people how they define the American Dream and chances are they’ll say, “Success.” The dream of individual opportunity has been home in American since Europeans discovered a “new world” in the Western Hemisphere. Early immigrants like Hector St. Jean de Crevecoeur praised highly the freedom and opportunity to be found in this new land. His glowing descriptions of a classless society where anyone could attain success through honesty and hard work fired the imaginations of many European readers: in Letters from an American Farmer (1782) he wrote. “We are all excited at the spirit of an industry which is unfettered and unrestrained, because each person works for himself ... We have no princes, for whom we toil,starve, and bleed: we are the most perfect society now existing in the world.” The promise of a land where “the rewards of a man’s industry follow with equal steps the progress of his labor” drew poor immigrants from Europe and fueled national expansion into the western territories.
Our national mythology is full of illustration the American success story. There’s Benjamin Franklin, the very model of the self-educated, self-made man, who rose from modest origins to become a well-known scientist, philosopher, and statesman. In the nineteenth century, Horatio Alger, a writer of fiction for young boys, became American’s best-selling author with rags-to-riches tales. The notion of success haunts us: we spend million every year reading about the rich and famous, learning how to “make a fortune in real estate with no money down,” and “dressing for success.” The myth of success has even invaded our personal relationships: today it’s as important to be “successful” in marriage or parenthoods as it is to come out on top in business. long prom dresses
But dreams easily turn into nightmares. Every American who hopes to “make it” also knows the fear of failure, because the myth of success inevitably implies comparison between the haves and the have-nots, the stars and the anonymous crowd. Under pressure of the myth, we become indulged in status symbols: we try to live in the “right” neighborhoods, wear the “right” clothes, eat the “right” foods. These symbols of distinction assure us and others that we believe strongly in the fundamental equality of all, yet strive as hard as we can to separate ourselves from our fellow citizens. short prom dresses

Ailments

Public distrust of scientists stems in part from the blurring of boundaries between science and technology, between discovery and manufacture. Most government, perhaps all governments, justify public expenditure on scientific research in terms of the economic benefits the scientific enterprise ha brought in the past and will bring in the future. Politicians remind their voters of the splendid machines ‘our scientists’ have invented, the new drugs to relieve old ailments, and the new surgical equipment and techniques by which previously intractable conditions may now be treated and lives saved. At the same time, the politicians demand of scientists that they tailor their research to ‘economics needs’, that they award a higher priority to research proposals that are ‘near the market’ and can be translated into the greatest return on investment in the shortest time. Dependent, as they are, on politicians for much of their funding, scientists have little choice but to comply. Like the rest of us, they are members of a society that rates the creation of wealth as the greatest possible good. Many have reservations, but keep them to themselves in what they perceive as a climate hostile to the pursuit of understanding for its own sake and the idea of an inquiring, creative spirit.
In such circumstances no one should be too hard on people who are suspicious of conflicts of interest. When we learn that the distinguished professor assuring us of the safety of a particular product holds a consultancy with the company ** it, we cannot be blamed for wondering whether his fee might conceivably cloud his professional judgment. Even if the professor holds no consultancy with any firm, some people many still distrust him because of his association with those who do, or at least wonder about the source of some his research funding. prom dresses 2012
This attitude can have damaging effects. It questions the integrity of individuals working in a profession that prizes intellectual honesty as the supreme virtue, and plays into the hands of those who would like to discredit scientists by representing then a venal. This makes it easier to dismiss all scientific pronouncements, but especially those made by the scientists who present themselves as ‘experts’. The scientist most likely to understand the safety of a nuclear reactor, for example, is a nuclear engineer declares that a reactor is unsafe, we believe him, because clearly it is not to his advantage to lie about it. If he tells us it is safe, on the other hand, we distrust him, because he may well be protecting the employer who pays his salary. prom dresses on sale

Dangerous

Though pacemakers require only small amounts of energy (about 1 millionth of a Watt), their batteries have to be replaced periodically, which means multiple surgeries for patients. Researchers have searched for ways to prolong battery life -- trying to generate energy to power a pacemaker using blood sugar, or the motion of the hands and legs -- but these methods either interfere with metabolism or require a more drastic surgery, such as passing a wire from the limbs to the chest area. Aerospace engineers M. Amin Karami and Daniel J. Inman, from the University of Michigan in Ann Arbor, have developed a prototype device that could power a pacemaker using a source that is surprisingly close to the heart of the matter: vibrations in the chest cavity that are due mainly to heartbeats. short prom dresses

The authors describe the technique and their progress developing it in a paper recently published in the AIP's Applied Physics Letters.

In their method, vibrations in the chest cavity deform a layer of piezoelectric material, which is able to convert mechanical stress into electrical current. Tests indicate that the device could perform at heart rates from 7 to 700 beats per minute (well below and above the normal range), and that it could deliver eight times the energy required for a pacemaker. Furthermore, the authors write, the amount of energy generated is always larger than the amount required to run a pacemaker, regardless of heart rate. short prom dresses 2012

Though the team has yet to develop a prototype that is biocompatible, they say that the potential to package this energy harvester with pacemakers gives it an advantage over competing methods.

Oozing sap

new discovery in a one-of-a-kind fossil shows that "bat flies" have been doing their noxious business with bats for at least 20 million years. For bats, that's a long time to deal with a parasite doing its best vampire impression. Maybe it is nature's revenge on the vampire bat, an aggressive blood consumer in its own right that will feed on anything from sheep to dogs and humans.

The find was made by researchers from Oregon State University in amber from the Dominican Republic that was formed 20-30 million years ago. The bat fly was entombed and perfectly preserved for all that time in what was then oozing tree sap and later became a semi-precious stone. prom dresses 2012

This is the only fossil ever found of a bat fly, and scientists say it's an extraordinary discovery. It was also carrying malaria , further evidence of the long time that malaria has been prevalent in the New World. The genus of bat fly discovered in this research is now extinct.

The findings have been published in two professional journals, Systematic Parasitology and Parasites and Vectors. prom dresses on sale

"Bat flies are a remarkable case of specific evolution, animals that have co-evolved with bats and are found nowhere else," said George Poinar, Jr., an OSU professor of zoology and one of the world's leading experts on the study of ancient ecosystems through plants and animals preserved in amber.

"Bats are mammals that go back about 50 million years, the only true flying mammal, and the earliest species had claws and climbed trees," Poinar said. "We now know that bat flies have been parasitizing them for at least half that time, and they are found exclusively in their fur. They are somewhat flat-sided like a flea, allowing them to move more easily through bat fur."

Not every bat is infested with bat flies, and some of the contemporary flies are specific to certain species of bats. But they are still pretty common and found around the world. long prom dresses

Bat flies only leave their bat in order to mate, Poinar said, and that's probably what this specimen was doing when it got stuck in some sticky, oozing sap.
