How to Do It: Making Paper by Hand

This is the VOA Special English Development Report.
The earliest process of making paper was done almost five thousand years ago in Egypt and the Nile Valley. In those days, paper was made from strips of the papyrus plant.
Modern paper-making began in China about two thousand years ago. This process produced paper from cloth, straw, wood or the bark of trees. The raw materials are struck over and over until they become loose. Then they are mixed with water.
After the water has been removed, the flat, thin form remaining is permitted to dry. This becomes a sheet of paper.
Large machines started to be used for making paper near the end of the sixteenth century. Today, paper-making is a big business. But it is still possible to make paper by hand, since the steps are the same as using big machines.
You should choose paper with small amounts of printing. Old envelopes are good for this reason. Colored paper also can be used, as well as small amounts of newspaper. Small pieces of rags or cloth can be added. These should be cut into pieces about five centimeters by five centimeters.
Everything is placed in a container, covered with water and brought to a boil. It is mixed for about two hours with some common chemicals and then allowed to cool. Then it is left until most of the water dries up. The substance left, called pulp, can be stored until you are ready to make paper.
When you are ready, the pulp is mixed with water again. Then the pulp is poured into a mold. The mold is made of small squares of wire that hold the shape and thickness of the paper. To help dry the paper, the mold lets the water flow through the small wire squares.
After several more drying steps, the paper is carefully lifted back from the mold. It is now strong enough to be touched.
The paper is smoothed and pressed to remove trapped air. You can use a common electric iron used for pressing clothes.
There are many other technologies for people making paper using small machines.
Internet users can do a search and find directions for making homemade paper.  You can also order information about making paper from the group EnterpriseWorks/VITA. Its Web site is enterpriseworks.org.

Some Tips for Cold Storage of Foods

This is the VOA Special English Development Report.
Before refrigerators were invented, the next best thing was an ice box. But another way to keep food fresh is to use an evaporative cooler. A common design is a tall box with several shelves inside to hold the food. The shelves are pieces of metal with many small holes through them. The sides of the box are covered with pieces of thick cloth.
Containers of water are placed at the top and bottom of the cooler. The ends of each piece of cloth lie in the water so the cloth stays wet.
The cooler is put outdoors, but not in the sun. Air will pass through the wet cloth. The inside of the box will stay several degrees cooler than the outside air temperature. And this may be cool enough to keep foods fresh, at least for a short time.
Some foods can make you sick if they are stored in conditions that are not cold enough to prevent the growth of harmful organisms. Freezing can keep some foods in good condition for months after the growing season. Yet foods can be damaged if they are kept too cold.
The British development group Practical Action says the best way to prepare foods for storage is at harvest time while still in the field.
Use a sharp knife and place the harvested items on a clean surface or directly into storage containers. Do not put them on the ground.
Use clean water to remove dirt, and keep the water clean. Usually it is better not to remove outer leaves from fruits and vegetables before storage. Without the leaves, food can become dry.
Fruits and vegetables must be cool from field heat before they are put into storage. But cooling them in water can spread fungus throughout the food. A better idea is to harvest foods either early or late in the day, then leave them to cool naturally.
Some fruits and vegetables must be stored at zero to four degrees Celsius. Any colder, and they might be damaged. Some foods need to be stored at four to eight degrees, and some need to be stored above eight degrees for best results.
Wet the fruits and vegetables so they do not become too dry. The best time to do this is before storage. Cover the items in plastic once they reach the right "critical temperature" for storage. Most fruits and vegetables need the relative humidity in storage to be kept between eighty-five and ninety-five percent.
Finally, leave space between the food containers and the walls of the cold storage area so air can flow. Keep the space clean. And try not to open the doors too often.

Studying at an American University, Just Not in the US

This is the VOA Special English EDUCATION REPORT.
This week in our series on American higher education, we discuss programs that are available in the Middle East.
We talked last week about Michigan State University which opened a campus in August in the United Arab Emirates. MSU Dubai offers undergraduate degrees in areas including business, engineering, education and telecommunications. It also offers some graduate programs.
This October, Michigan State plans to open a pre-college program -- the MSU Dubai Academy. The aim is to help foreign students prepare to attend an American school.
Other American universities with campuses in the Middle East include Carnegie Mellon, Cornell, Georgetown, Northwestern, Texas A&M and Virginia Commonwealth. They have campuses in Qatar. New York University plans to open a campus in Abu Dhabi in two thousand ten.
But the worldwide economic downturn is affecting the plans of some schools. For example, earlier this year Bryn Mawr College in Pennsylvania suspended its plans to open a campus in Abu Dhabi.
And George Mason University in Virginia is closing its campus in Ras Al Khaimah, another of the United Arab Emirates. One reason is the recession. But the campus Web site says that several issues made it impossible for the university to offer the same quality education as in the United States.
University Provost Peter Stearns tells us that the effort failed largely because of a dispute with their local partner in the campus. The disagreement involved the operating budget and academic control.
The George Mason campus opened in two thousand six. But student numbers have been disappointing. Peter Stearns says the campus had between two hundred fifty and three hundred students this year. He says more than fifty of them hope to attend the home campus in Fairfax, Virginia, in September.
And he says George Mason will remain involved in education in the Middle East as an adviser to the American University in Dubai.
The Harvard Medical School Dubai Center was launched in two thousand four. It offers professional development and postgraduate training but no degree programs. Harvard says it has no plans for a campus, but wants to help Dubai develop its Academic Medical Center.
And that's the VOA Special English EDUCATION REPORT, written by Nancy Steinbach. Earlier reports in our Foreign Student Series are at voaspecialenglish.com. I'm Steve Ember.

Correction: George Mason University will remain an adviser to the American University of Ras Al-Khaimah, not the American University in Dubai as incorrectly reported.

Foreign Graduates and Jobs

This is the VOA Special English EDUCATION REPORT.
We answered a question last week about how American college students find jobs after they graduate. Now, we discuss foreign graduates. The process for employing foreign workers in the United States is long. It involves different government agencies. It also involves a hot political issue.
For example, the American Recovery and Reinvestment Act that President Obama signed into law in February dealt with this issue. It included conditions against foreign workers displacing qualified Americans at companies that receive federal stimulus money.
Job cuts have slowed in some industries. But the economic downturn has cost millions of jobs and recovery will take some time.
Foreign graduates need a job offer to get an H-1B visa. This is a non-immigrant visa for work in the person's area of specialty. The employer is the one who applies for it. The visa is good for three years and may be extended for another three years.
Cheryl Gilman directs visa services at the University of Southern California in Los Angeles. She noted that H-1B visas were still available for next year. This tells her that the recession is preventing employers from sponsoring as many foreign nationals as they have in the past.
Sixty-five thousand H-1Bs are awarded each year to graduates with a bachelor's degree. Bill Wright at the Department of Homeland Security says fewer than forty-five thousand applications for these visas had been received as of this week.
There was more demand for twenty thousand other H-1Bs for those with advanced degrees. In addition, thousands of the visas are awarded to other groups, such as university researchers.
Amy Ramirez is an administrator at Johns Hopkins University in Maryland. She says foreign students who work for their school or at an internship probably have the best chance for a job after graduation.
She points out that many foreign graduates ask to stay for what is called optional practical training. This lets them accept temporary employment in their area of study for twelve months after graduation.
Many times, the employer will then apply for an H-1B. But Amy Ramirez and Cheryl Gilman both say foreign students should understand that visa rules change often. That can make it difficult to plan ahead for what to do after graduation.

Getting a US Visa


Download MP3   (Klik kanan dan Save as (Simpan sebagai)
This is the VOA Special English EDUCATION REPORT.
This week, in part nine of our Foreign Student Series, we talk about getting a student visa to come to the United States.
Just getting accepted to an American college or university does not guarantee that you will get a visa. And getting a visa just lets you arrive in the United States. It does not guarantee that an immigration officer will permit you to enter the country.
Travel documents come from the Department of State. But immigration is the responsibility of the Department of Homeland Security.
The State Department has a Web site with all the rules for getting a visa. The address is unitedstatesvisas.gov. Unitedstatesvisas is all one word.
If you are requesting a visa for the first time, you will probably have to go to an American embassy or consulate. You will need to bring a government form sent to you by your American school that shows you have been accepted.
You will also need banking and tax records that show you have enough money to pay for your education. And be prepared to provide evidence that you will return to your home country after your studies end.
All of this is important in satisfying the requirements to get a visa. A consular official will also take your picture and your fingerprints.
Foreign students must contact their local embassy or consulate to request an interview and to get other information. This includes directions about how and where to pay the visa application charge. The cost is two hundred dollars.
You should apply for the visa as soon as you have been accepted to a school in the United States. The government needs time to perform a background investigation.
You cannot receive a visa more than one hundred twenty days before the start of your program. And if you are coming as a student for the first time, you cannot enter the country more than thirty days before classes begin.
Once you come to the United States, you can stay for the length of your period of study. Your school is required to provide the Department of Homeland Security with reports on your status as a student. We will talk more about what that means next week.
And that's the VOA Special English EDUCATION REPORT, written by Nancy Steinbach. Our Foreign Student Series is online with transcripts, MP3s and helpful links at voaspecialenglish.com. I'm Steve Ember.

Rock Climbing


Download MP3   (Klik kanan dan Save as (Simpan sebagai)
I'm Doug Johnson. And I'm Bob Doughty with EXPLORATIONS in VOA Special English. Some people say the higher you climb, the harder you fall. But those people probably would not be rock climbers. The sport, science and art of rock climbing is our subject this week.
An estimated nine million people rock climb in the United States. Millions more take part in the activity around the world. Some do it just for personal satisfaction. Others compete. Rock climbing can be dangerous. But there are many methods and protective devices that can increase a climber's safety.
Climbing takes strength, control and good balance. Climbers have to pull themselves straight up the face of very high rocks or walls. So they have to be strong enough to carry their own weight. And climbers sometimes have to hold on to rocks by only their fingers or toes.
There are several kinds of rock climbing. Traditional rock climbing is done outside. Climbers wear ropes and attach devices to the rocks as they climb many hundreds of meters up. They also connect their ropes to the devices. If a climber slips, a rope can stop him from falling.
Sport climbing is similar. However, in those cases the protective devices are permanently placed in the rock. There is also indoor climbing. Rock walls made of wood or concrete have places for the climber's hands and feet.
Ice climbing is exactly as it sounds. People climb glaciers or frozen waterfalls instead of rocks. They use special equipment for the ice.
And then there is bouldering – climbing rocks between three and seven meters high. It is a quicker and more intense kind of climbing. Many climbers like bouldering because they can use less equipment. Climbers often need only special shoes and chalk. All climbers use chalk to keep their hands dry.
Most rocks have cracks and holes and parts that stick out. Climbers use these for footholds and handholds. Sometimes the rock curves into an overhang. Then a climber has to try to move sideways as she moves forward to try to avoid hanging completely upside down.
Climbers use their legs to climb. They try not to pull themselves up with their hands or arms. Arms and hands are for position and balance. Climbers often need to lock their bodies to the rock with one small finger hold.
People almost always climb in groups of two or more. Climbing alone, or "solo climbing," is very dangerous. Expert rock climbers say only the very best in the sport should do it.
In a group climb, the first climber is the lead climber. He has a rope attached to his harness. The harness goes around the middle of the climber's body and in between his legs. The second climber is called the belayer. The lead climber's rope goes through a belay device. It is attached to the belayer's harness. The belayer then gives more rope up to the lead climber as he moves up the rock.
The lead climber attaches his rope to devices in the rock as he climbs up. If he falls, he is protected by the rope connected to the devices and the belayer. But, the lead climber can only do this for about twenty-five meters, the length of the climbing ropes. If the lead climber were injured in a fall from any higher up, the belayer could not get him down. Later, the lead climber and the belayer change places. They meet where the first climber has stopped. Then they start to climb again.
Sarah Bowman is a twenty-six-year-old rock climber in Alexandria, Virginia. She started climbing a year and a half ago. Her first experience with the sport probably was not the usual kind. It was during a visit to Alaska.
SARAH BOWMAN: "So, I ran a marathon and two days later I went ice climbing on a glacier. And, then I decided to come back home and see if there was a gym, so…"
She says she fell in love with the sport.
SARAH BOWMAN: "It's sort of like a world on its own. There's no other sport where you're really going up and down. Everything else is across the ground. In basketball you go up a little bit, but not anywhere near as cool. So I think most people love it or hate it. There's really no in between."
Ms. Bowman continued her training.
SARAH BOWMAN: "So, I'm also now a wilderness EMT so it's totally a good thing to have when you're out rock climbing."
Ms. Bowman works at an indoor climbing center. She says all climbers go to these centers in the winter when it is too cold to climb outdoors. At indoor centers, climbers have many different paths they can use to get to the top of the walls. The possibilities are marked by tape of different colors. If you start a path of one color you must continue to use only toe and handholds marked with that color. The different paths have different levels of difficulty. While our reporter was there, Sarah Bowman succeeded at a personal best.
The Sportrock Climbing Center is busy even at nine-thirty on a Monday night. An equal number of young men and women crowd around several different climbing walls. Climbers stretch their bodies in ways that do not seem possible while hanging in positions that do not seem to obey the laws of physics. They try to move as silently up the wall as they can. Sarah Bowman says being quiet is considered an important climbing skill. However, fans on the ground cheer them on as they climb up the wall.
This past summer the rock climbing world mourned the loss of one of its greatest stars. John Bachar was fifty-two years old when he fell from Dike Wall near his home in Mammoth Lakes, California. He was doing what he was famous for -- free-solo climbing. This is climbing without protection and alone.
John Bachar was born in Los Angeles and became famous in Yosemite Valley in California. That area of Yosemite National Park is the traditional international center of rock climbing.
Mr. Bachar started free-solo climbing in the nineteen seventies. He was a member of a group of climbers called the Stonemasters. Another climber, John Lang, suggested Bachar free-solo an area called Double Cross, in Joshua Tree National Park, California. John Bachar accepted the dare and never looked back.
By nineteen eighty-one, John Bachar proposed a dare himself. He offered ten thousand dollars to anyone willing to follow him on a one-day climb without a rope. No one accepted.
Dean Fidelman is a professional rock climber who was a close friend of John Bachar. We spoke to Mr. Fidelman as he was climbing. He said John Bachar often compared himself to a dancer who was always working on his dance. Mr. Bachar was known for his slow, smooth and controlled movements while climbing.
Dean Fidelman said that he believes a climber's ego can be his worst enemy on a rock. He said rock climbing is a high risk sport in which many people overestimate their abilities and underestimate the rock.
A recent study shows a sharp increase in rock climbing injuries between nineteen ninety and two thousand seven. The Center for Injury Research and Policy at Nationwide Children's Hospital in Ohio did the study. It was published in the American Journal of Preventative Medicine. The study found a sixty-three percent increase in the number of people treated for rock climbing injuries in American hospitals.
The study said forty thousand people were treated in emergency rooms. The most common injuries were broken bones and sprains in legs and feet. The ankle was the most common body part to be injured.
Climbers in the study were from ages two to seventy-four. The average age was twenty-six. Fifty-six percent of the injuries were to people twenty to thirty-nine years old. Women made up twenty-nine percent of the injured population. That is more than in past rock climbing studies.
Like many other sports, rock climbing can be dangerous. But many people think it is worth it. John Bachar said rock climbing felt like being on another planet. Dean Fidelman says it is a continual challenge and a beautiful form of movement. And, for Sarah Bowman, she has just started her way up the rocks.

Seven Man-Made Wonders in the US The Golden Gate Bridge, the Brooklyn Bridge, the Gateway Arch, Mount Rushmore, Hoover Dam, the Mesa Verde Cliff Dwellings, and the Space Needle

I'm Faith Lapidus. And I'm Steve Ember with EXPLORATIONS in VOA Special English.
There are many natural wonders in the United States. Today, we take you to seven man-made wonders in America.Against the city's gleaming spires,
Above the ships that ply the stream,
A bridge of haunting beauty stands –
Fulfillment of an artist's dream.

That poem is about our first man-made wonder -- the Brooklyn Bridge in New York City.  It extends more than 480 meters over the East River to connect the areas of Brooklyn and Manhattan.  A famous bridge builder David B. Steinman wrote the poem.  But he did not build the Brooklyn Bridge.
It was the dream of another man, John A. Roebling.  He was a member of the design team and became chief engineer of the building project in 1867.  Sadly, he became sick and died before work even started.  He had an accident when visiting the area where the bridge was to be built
Building began in 1870. It was very dangerous.  Few records were kept on such events.  But, historians say between 20 and 30 men died as a result of the building project.  Some died from falling off the bridge or from being struck by equipment.
Others died or were injured from working in the structures called caissons.  These lay deep below the surface of the Earth.  The workers would get a pressure sickness called the bends.
John Roebling's son, Washington, was severely disabled by the bends. He had been named chief engineer of the Brooklyn Bridge project soon after his father died. Washington Roebling continued the work from his home after he was disabled.
The Brooklyn Bridge opened on May 24, 1883. At the time, it was the longest suspension bridge in the world.  It is still a beautiful structure.  The bridge has tens of thousands of suspension wires that spread many meters across and up and down to towers on each side.  From a distance the many wires look like the stringed musical instrument called the harp.  The center of the Brooklyn Bridge rises almost 40 meters above the East River.  It is one of the most famous and beloved New York City landmarks.Another bridge makes our list of the seven man-made wonders.  This one is in northern California.
The Golden Gate Bridge is named after the waterway it crosses.  The Golden Gate Strait lies between the Pacific Ocean and the San Francisco Bay.  The bridge over it links the city of San Francisco with Marin County.
Joseph Strauss was the chief engineer of the Golden Gate Bridge. Building began in 1933.  The bridge opened in 1937.  It is almost 1,300 meters long.  It was the longest suspension bridge in the world for almost 30 years.  Then, in 1964, the larger Verrazano Narrows bridge opened in New York City.
Joseph Strauss used newly developed protective equipment for the men who worked on the bridge.  These included a special safety net under the bridge. But still, 11 men were killed during construction
The color of the bridge, International Orange, is very important.  It was chosen partly because it is easier to see through the heavy fog that often covers San Francisco. Many people consider the Golden Gate Bridge the most beautiful bridge structure in the world.
Joseph Strauss wrote a poem about his bridge when the work was done.  Here is a part of "The Mighty Task is Done":
At last the mighty task is done;
Resplendent in the western sun
The Bridge looms mountain high;
Its titan piers grip ocean floor,
Its great steel arms link shore with shore,
Its towers pierce the sky.Our next man-made wonder is as famous a landmark in the Midwest United States as the first two are on the East and West Coasts.  The Gateway Arch in Saint Louis, Missouri is the tallest freestanding monument in the nation.  The shiny, steel curve rises to almost 200 meters.  Below, the arch is exactly as wide as it is tall.

The famous Finnish American building designer, Eero Saarinen, designed the Gateway Arch during a national competition in the late 1940s.  However, building did not begin until February, 1963. It was completed in October, 1965.  Later a transport system was added to permit people to visit an observation area inside the top of the arch.
The Gateway Arch rises above the Mississippi River.  It was named in honor of Saint Louis, which was historically called "The Gateway to the West."There is one place in America that almost everyone agrees is a man-made wonder: South Dakota's Mount Rushmore
Giant faces of four great American presidents are cut into the rock near the top of Mount Rushmore in the Black Hills. Each face is about 18 meters high.
Sculptor Gutzon Borglum was chosen to create the Mount Rushmore memorial. It was completed in 1941, after 14 years.
Each president represents important values in America.  George Washington led the cause for independence.  Thomas Jefferson represented the belief in equality.  Abraham Lincoln ended slavery and saved the Union. And Theodore Roosevelt was a conservationist and symbol of the progressive spirit of America.We go next to one of the largest and most difficult structures ever built in the United States: Hoover Dam.  The dam is in the Black Canyon, near Las Vegas, Nevada.  It controls the water of the Colorado River and produces electric power.
Workers began to build Hoover Dam in 1931.  They finished in just five years.
More than 20,000 men worked on the project.  It was very dangerous.  Ninety-six workers were killed. Many others were injured.
The Hoover Dam is 221 meters tall. It weighs more than six and one half million tons.  At the time, it was the largest and tallest dam in the world. And it was one of the largest producers of electric power ever built.
Hoover Dam also created Lake Mead, the largest man-made lake in AmericaAnother man-made wonder of the United States was built long before the nation was established.  About 900 years ago, the Ancestral Puebloan people built villages high in the walls of canyons in Mesa Verde, Colorado. Six hundred cliff dwellings are now part of the Mesa Verde National Park.
Visitors can stand at the top of the mesas and look into the dwellings almost hidden in openings of the rock walls.  The Puebloan people cut small steps into the rock.  A series of such steps connected buildings containing hundreds of rooms.
The rock walls have protected the buildings from severe weather in the area.
So they remain mostly unchanged in the hundreds of years since they were built.Our final man-made wonder is in the northwestern city of Seattle, Washington.  The Space Needle was built as the central structure for the 1962 World's Fair.
Edward Carlson designed the 184 meter tall structure.  The Space Needle has a wide base on the ground. It is narrow in the middle.  On top is a large ring-like structure.
The structure was meant to look like a "flying saucer," a vehicle that was popular in science fiction space travel stories.  The saucer includes an observation area and eating place.  The restaurant slowly turns to provide visitors with a 360 degree view of Seattle.
The Space Needle was not very costly.  The building project cost about 4,500,000 dollars.  It was designed and completed in about a year and opened on the first day of the World's Fair.
Today, the Space Needle is the most popular place for visitors to Seattle. And it remains the internationally known symbol of the city.This program was written and produced by Caty Weaver.  I'm Faith Lapidus.

Betty Friedan, 1921-2006: A Leader in the Modern Women's Rights Movement


Download MP3   (Klik kanan dan Save as (Simpan sebagai)
I'm Faith Lapidus. And I'm Steve Ember with PEOPLE  IN AMERICA in VOA Special English.  Today we tell about Betty Friedan.  She was a powerful activist for the rights of women.
Betty Friedan is often called the mother of the modern women's liberation movement.  Her famous book, "The Feminine Mystique," changed America.  Some people say it changed the world.  It has been called one of the most influential nonfiction books of the twentieth century.
Friedan re-awakened the feminist movement in the United States.  That movement had helped women gain the right to vote in the nineteen twenties.  Modern feminists disagree about how to describe themselves and their movement.  But activists say men and women should have equal chances for economic, social and intellectual satisfaction in life.
Fifty years ago, life for women in the United States was very different from today.  Very few parents urged their daughters to become lawyers or doctors or professors. Female workers doing the same jobs as men earned much less money.  Women often lost their jobs when they had a baby.  There were few child care centers for working parents.
Betty Friedan once spoke to ABC television about her support for sharing responsibility for the care of children:
"If child-rearing was considered the responsibility of women and men or women and men and society, then we really could pull up our skirts and declare victory and move on."
Betty Friedan was born Betty Goldstein in nineteen twenty-one in Peoria, Illinois.  Her immigrant father worked as a jeweler.  Her mother left her job with a local newspaper to stay home with her family.
Betty attended Smith College in Northhampton, Massachusetts. It was one of the country's best colleges for women. She finished her studies in psychology in nineteen forty-two.
After college she attended the University of California at Berkeley to continue her studies.  But her boyfriend at the time did not want her to get an advanced degree in psychology. He apparently felt threatened by her success.  So Betty left California and her boyfriend.  She moved to New York City and worked as a reporter and editor for labor union newspapers.
In nineteen forty-seven, Betty Goldstein married Carl Friedan, a theater director who later became an advertising executive.  They had a child, the first of three.  The Friedans were to remain married until nineteen sixty-nine.
When Betty Friedan became pregnant for the second time, she was dismissed from her job at the newspaper.  After that she worked as an independent reporter for magazines.  But her editors often rejected her attempts to write about subjects outside the traditional interests of women.
In nineteen fifty-seven, Friedan started research that was to have far-reaching results.  Her class at Smith College was to gather for the fifteenth anniversary of their graduation. Friedan prepared an opinion study for the women.  She sent questions to the women about their lives. Most who took part in the study did not work outside their homes.
Friedan was not completely satisfied with her life. She thought that her former college classmates might also be dissatisfied.  She was right.  Friedan thought these intelligent women could give a lot to society if they had another identity besides being homemakers.
Friedan completed more studies. She talked to other women across the country.  She met with experts about the questions and answers.  She combined this research with observations and examples from her own life.  The result was her book, "The Feminine Mystique," published in nineteen sixty-three.
The book attacked the popular idea of the time that women could only find satisfaction through being married, having children and taking care of their home. Friedan believed that women wanted more from life than just to please their husbands and children.
The book said women suffered from feelings of lack of worth. Friedan said this was because the women depended on their husbands for economic, emotional and intellectual support.
"The Feminine Mystique" was a huge success.  It has sold more than three million copies.  It was reprinted in a number of other languages.   The book helped change the lives of women in America. More women began working outside the home. More women also began studying traditionally male subjects like law, medicine and engineering.
Betty Friedan expressed the dissatisfaction of some American women during the middle of the twentieth century. But she also made many men feel threatened. Later, critics said her book only dealt with the problems of white, educated, wealthy, married women. It did not study the problems of poor white women, single women or minorities.
In nineteen sixty-six, Betty Friedan helped establish NOW, the National Organization for Women.  She served as its first president.  She led campaigns to end unfair treatment of women seeking jobs.
Friedan also worked on other issues.  She wanted women to have the choice to end their pregnancies.  She wanted to create child-care centers for working parents. She wanted women to take part in social and political change.  Betty Friedan once spoke about her great hopes for women in the nineteen seventies:
"Liberating ourselves, we will then become a major political force, perhaps the biggest political force for basic social and political change in America in the seventies."
Betty Friedan led a huge demonstration in New York City for women's rights. Demonstrations were also held in other cities.   A half-million women took part in the Women's Strike for Equality on August twenty-sixth, nineteen seventy.  The day marked the fiftieth anniversary of American women gaining the right to vote.
A year after the march, Friedan helped establish the National Women's Political Caucus.  She said the group got started "to make policy, not coffee."  She said America needed more women in public office if women were to gain equal treatment.
Friedan wanted a national guarantee of that equal treatment. She worked tirelessly to get Congress and the states to approve an amendment to the United States Constitution that would provide equal rights for women.
The House of Representatives approved this Equal Rights Amendment in nineteen seventy-one. The Senate approved it the following year. Thirty-eight of the fifty state legislatures were required to approve the amendment.  Congress set a time limit of seven years for the states to approve it. This was extended to June thirtieth, nineteen eighty-two.  However, only thirty-five states approved the amendment by the deadline so it never went into effect.
The defeat of the E.R.A. was a sad event for Betty Friedan, NOW and other activists.
In nineteen eighty-one, Betty Friedan wrote about the condition of the women's movement.  Her book was called "The Second Stage."  Friedan wrote that the time for huge demonstrations and other such events had passed.  She urged the movement to try to increase its influence on American political life.
Some younger members of the movement denounced her as too conservative.
As she grew older, Friedan studied conditions for older Americans.  She wrote a book called "The Fountain of Age" in nineteen ninety-three. She wrote that society often dismisses old people as no longer important or useful. Friedan's last book was published in two thousand.  She was almost eighty years old at the time.  Its title was "Life So Far."
Betty Friedan died on February fourth, two thousand six.  It was her eighty-fifth birthday. Betty Friedan once told a television reporter how she wanted to be remembered:
"She helps make it better for women to feel good about being women, and therefore she helped make it possible for women to more freely love men."

Classical Music, but With a Modern Sound

Welcome to THIS IS AMERICA in VOA Special English. I'm Steve Ember.
And I'm Barbara Klein. This week we begin the first of two programs about classical music composers at work today in the United States. Some continue the traditions of European music from centuries ago. Others take a more experimental approach to their music.
(MUSIC: Symphony No. 1/Indianapolis Symphony Orchestra)
We start with Ellen Taaffe Zwilich. Her music is often described as complex but accessible, appealing to wider audiences. In nineteen eighty-three she became the first female composer to win a Pulitzer Prize. She won it for her Symphony Number One.
She says this is a special time to be a composer. Thanks to technology, more music is available to more people than at any time in history.
Ellen Zwilich began her musical exploration playing the piano, violin and trumpet. She started writing music as a child. She studied music at Florida State University and later moved to New York City to study violin and composition.
One of Ellen Zwilich's teachers has been a big part of American classical music for over seventy years: Elliott Carter.
This is Elliott Carter's Double Concerto for Harpsichord, Piano and Two Chamber Orchestras.
He began his musical studies at Harvard University in the nineteen thirties and went on to study in Paris.
His early works were influenced by composers of the classical period of the late seventeen hundreds and early eighteen hundreds. But he later broke away from this neoclassical sound to create a freer and more expressive modernist sound.
Elliott Carter has written over one hundred thirty works, many of which he composed after the age of ninety. He is one hundred one years old.
(MUSIC: ''Facades"/Philip Glass)
The music of Philip Glass is often described as minimalist, though not by him. He would rather people describe his music as having repeating structures.
Philip Glass experiments with many different sounds. He has written operas, concertos and symphonies. He has worked on projects with singers, dancers and artists. He has also written music for many movies, including "Koyaanisqatsi," "Kundun" and "The Hours."
Becoming a composer generally starts with musical training and education.
There are many well-known music schools in the United States. These include the Juilliard School in New York City and the Peabody Institute of Johns Hopkins University in Baltimore, Maryland. Others include the Oberlin Conservatory of Music in Ohio and the Berklee College of Music in Boston, Massachusetts.
Boston is also the home of the New England Conservatory of Music, the nation's oldest independent music school.
And it is not just Americans who study at these schools. At the Manhattan School of Music in New York, for example, an average of thirty-five percent of the students come from outside the United States.
Carol Aicher is a professor at the Manhattan School of Music. We asked her how success is defined for a composer today.
Success, she says, is all about getting your music played. Having established groups hire composers to write new music is important, but that is not enough.
Professor Aicher explains that many composers have exciting premieres, where their music is played in public for the first time. But she says the real measure of success is whether or not their music gets replayed. For example, performance groups might buy the rights to play the work live. Or the music might get recorded and sold on CD or online.
Carol Aicher says most composers teach at music schools to add to their income.
(MUSIC: "Secret and Glass Gardens"/Jennifer Higdon, pianist Maria Mazo)
Jennifer Higdon clearly fits the description of a successful composer. Her works are played by orchestras and at music festivals around the world, and this year she won a Pulitzer Prize.
Yet she came relatively late to music. She taught herself to play the flute at the age of fifteen. She began her musical schooling three years later. Soon, she became interested in composing. She currently teaches composition at the Curtis Institute of Music in Philadelphia, Pennsylvania.
For a classically trained composer, Jennifer Higdon's musical influences might surprise you.
JENNIFER HIGDON: "The Beatles. That's probably the first influence. Lennon and McCartney, because I listened to so much of it growing up. I actually didn't grow up listening to classical music."
She is known for choosing unusual instruments and sounds. In a recent concerto piece called "On a Wire" she had the musicians play a bowed piano. They took the hairs off the kind of bow used to play a violin or cello and placed them inside the piano, under the strings.
JENNIFER HIGDON: "It makes for this haunted sort of sound. It's a little bit like a wine glass, when you play a wine glass. It's very unusual."
One of her more widely performed works is "blue cathedral." She says the work is a poem about the people who cross our paths in a lifetime. It was influenced by her brother's death from cancer.
(MUSIC: "blue cathedral"/Atlanta Symphony Orchestra)
We asked Jennifer Higdon how she goes about planning a new work.
JENNIFER HIGDON: What I do is I always know who I am writing for, I always know the ensemble or the soloist. And I know how long a piece they want. Then I daydream a lot, trying to figure out what might be interesting for that group to do."
She writes down her ideas with a pencil in a music notebook. She considers not only what would be interesting for the musicians to play, but also what would be interesting for the audience to hear.
JENNIFER HIGDON: "There's a lot of sketching that goes on, and a lot of times I don't know where things are going to fit in the texture. I may come up with an idea and it may end up being something in the middle of the piece. When I wrote 'blue cathedral' there is a huge English horn solo in the middle of it, and that's actually the first idea I came up with."
Next, she plays some ideas on the piano before entering the beginnings of a composition into a computer.
Jennifer Higdon says the classical music world still has a way to go in supporting more women composers, as well as conductors. She considers composers like Ellen Zwilich and Libby Larsen to be mentors who opened up possibilities to her.
JENNIFER HIGDON: "I was very lucky because my parents never discouraged me. They never said you can't do it because you're a woman, so it never occurred to me that I couldn't do it."
But she says things are starting to look better for women composers.
JENNIFER HIGDON: "We're starting to see a little bit of a change. I suspect my winning the Pulitzer this year will probably alter quite a bit because it meant that I was in the news enough that there's some little girl out there who says 'Oh! I can do that!'"
Jennifer Higdon is currently working on an orchestral piece for the Grand Teton Music Festival in Wyoming. The music will celebrate the festival's fiftieth anniversary next year.
Ms. Higdon says one important thing about her work is her general goal when writing music.
JENNIFER HIGDON: "I write music for people who may have no experience with classical music. I often think you don't need to have a [music] degree, you don't even need to have been to a concert hall."
Jennifer Higdon says she is always thinking about her audience when she is composing.
JENNIFER HIGDON: "What if this was someone coming to the music for the very first time? Maybe they've never heard classical music. So give it a chance, see what you think. There is some cool stuff out there."
(MUSIC: "String Poetic"/ Jennifer Higdon, violinist Jennifer Koh and pianist Reiko Uchida)

About Sharks and the Killing of Sharks

Download MP3 (Klik kanan dan Save as (Simpan sebagai)


This is SCIENCE IN THE NEWS in VOA Special English. I’m Christopher Cruise. And I’m Faith Lapidus.
This week, we tell about sharks. We tell how demand for shark fin soup has led to the killing of millions of these creatures. And we tell about tests on pieces of bone said to be from pilot Amelia Earhart.

Sharks

A picture in the newspaper shows a person standing next to a huge shark. The body of the shark is hanging with its head down. The words below the picture say the shark was a very big one. Or perhaps it was one of the biggest ever caught in the area. The person who brought in the shark is smiling. That person won a battle with what has been called one of nature’s fiercest creatures.
Some people, however, do not approve of catching sharks. They do not think all sharks are terrifying enemies. They know that studies show lightning and snakebites hurt more people than do shark attacks. Sharks kill about ten people a year. Yet people kill tens of millions of sharks a year.
Activists for sharks note that sharks are valuable in the ocean. They eat injured and diseased fish. Their hunting means other fish do not become too great in number. This protects other creatures and plants in the ocean.
Wildlife activists worry that some kinds of sharks are in danger of disappearing. The National Oceanic and Atmospheric Administration estimates fishing operations kill more than one hundred million sharks every year.
Sharks are harvested for meat and cartilage, liver oil and, especially, for their fins. And many sharks die when fishermen harvesting other kinds of fish pull in sharks by accident. Sharks are vulnerable to over-fishing. Sharks grow and develop slowly and do not produce many young.
George Burgess leads the International Shark Attack File at the Florida Museum of Natural History at the University of Florida in Gainesville. He says shark attacks increased during the past century for a good reason: hundreds of millions of people now use the world’s oceans.
The International Shark Attack File says the number of shark attacks rose twenty five percent last year. Seventy-nine shark attacks were reported in twenty ten. Six people were killed. The File gives likely reasons for the increase, including higher water temperatures because of unusually warm weather. There were thirty-six shark attacks in the United States -- the most of any country.
The International Shark Attack File describes shark attacks as either provoked or unprovoked. An unprovoked attack means the person is alive when bitten. It also means the person must not have interfered with the shark.
But some divers interfere with sharks on purpose. They want to get the attention of sharks, perhaps to take pictures of them. The diver may put food in the water to get the animal to come close. Sharks do not normally want to be with people. But their excellent sense of smell leads them to food.
Some experienced divers say they may not face danger when near a shark. But they say the next person who comes near the shark may be in trouble. The animal’s experience with being fed may make it connect food with people.
Some divers and filmmakers enter a shark’s territory while inside containers made of steel. Others wear heavy metal equipment for protection. And others get near sharks wearing only normal diving equipment.
This close contact with sharks has its critics. Some people say it is an invasion of the animals’ territory for no good reason. The contact can produce exciting films that may increase public interest and sympathy for sharks. But they may also make us more afraid of them.
Today, a major threat to sharks comes from shark fin soup. This food has increased in popularity over the years. Fisheries can earn a lot of money for even one kilogram of shark fins.
“Finning,” as it is called, is big business. Fishers cut off the shark’s fin while the shark is still alive and throw the animal back into the water. The shark is unable to swim or eat. In hours or days, it bleeds to death on the bottom of the ocean.
Wildlife protection groups and many people worldwide have denounced finning as torture. Some areas have banned this activity. But it is hard to enforce the ban in many places.
Many people want to save sharks and stop finning. One of them is John McCosker. He is the head of the aquatic biology department at the California Academy of Sciences. Professor McCosker has been studying sharks for more than thirty years. He says finning is not only cruel, but bad for the oceans.
JOHN MCCOSKER: “We must stop the shark-finning which is resulting in the death of thirty to seventy million sharks each year because that has so upset ocean ecology by the removal of these often apex, top-level predators.”
Professor McCosker says demand for shark fin soup is strong in China.
John McCosker: “It is a cultural tradition, and not all Asian cultures believe in it. But what it now is, is a demonstration really of wealth and status. Shark fin soup is usually served at weddings and at banquets, and it’s very expensive.”
The European Union, the nation of Guam and some individual American states want to stop finning. In January, President Obama signed a measure known as the Shark Conservation Act. The measure strengthens American laws against finning. It requires the fishing industry to bring sharks to port before their fins are cut.
Fishers can make a lot of money by selling shark fins. Professor McCosker believes the best way to stop finning is to educate owners of Chinese restaurants not to sell shark fin soup. He also wants to persuade people not to buy it.
State lawmakers in California are considering a bill that would make it illegal for people to have, sell or distribute shark fins. Supporters say the bill will help protect sharks. But opponents have described the measure as an attack on Chinese culture.
State Senator Leland Yee and Chinese restaurant owners say they are concerned about the overfishing of sharks. In fact, they want a federal law to ban the practice of finning. But Senator Lee says not all sharks are in danger of extinction. He says the proposed law to ban the eating of shark fins is an unfair attack on Asian culture and cuisine.

Amelia Earhart

The mystery of what happened to Amelia Earhart will go on. Earhart disappeared more than seventy years ago while attempting to fly around the world. Experts at the University of Oklahoma say they could not link a small piece of bone to the famous pilot. But they also say they will continue tests on a piece of soil or human waste.
The International Group for Historic Aircraft Recovery had asked the university to study the material. The group found it on an archeological dig on Nikumaroro, an island in the southwestern Pacific Ocean.
Nikumaroro was once called Gardner Island. It could have been on Earhart’s way to Howland Island. She and her navigator, Fred Noonan, were hoping to reach Howland to get more fuel for their airplane.
Historical records say Earhart died on July second, nineteen thirty seven, when her plane fell into the ocean after all its fuel was gone. But the International Group for Historic Aircraft Recovery disputes the official version of events. It suspects that she and Noonan found their way to Nikumaroro Island.
Members have repeatedly explored there over the years. They have found a number of objects that might be connected to Earhart. But a link between those objects and her or Noonan has yet to be firmly established.
Members recently found what could be a piece of human finger bone and the possible human waste. First tests of the bone fragment showed that human genetic material, human DNA, was present. But later tests could not repeat the results.
Scientist Cecil Lewis said the human DNA could have been there because people had had contact with the bone. Or, he said human DNA really was present in the bone, but the bone was too small or low-quality to repeat the first results. Or, the DNA in the bone might be non-human.
The test results of the piece of soil or waste material were more promising. These results showed human DNA.
Mr. Lewis said his team is using a genetic method to examine bacteria species inside the material. He said the presence of some plant and animal DNA would be a further sign that the piece is waste material. That material could contain information about what the individual was eating and his or her health.
