The passport photographs of the future could turn out to be more than just another pretty picture if a new computer technique developed by Israeli scientists catches on.
Researchers at Ben-Gurion University, in Israel, have invented a way to hide information such as a fingerprint or signature in color images. They believe this could improve passport safety or be used to produce product bar codes(条形码) or designs that cannot be seen.
“The papers can be faxed, scanned(扫描) and reprinted without hidden data disappearing,” New Scientist magazine said last week.
Joseph Rosen and a team of scientists worked out the new instrument by creating a mathematical model.
The model turns a fingerprint or signature into a series of numbers which are used to shape the dots that make up a color picture.
“Each dot can be forced out of the usual place slightly without noticeably changing the final appearance of the image,” the magazine said.
Several images that can be hidden in a single picture are scanned into a computer which does the work.
The hidden images or fingerprints cannot be shown until the picture is scanned again.
The computer rebuilds the fingerprint by measuring the displacement of the dots in the picture.
The magazine said that if he model is used for passport checkpoints the picture can be unscrambled(解码) to show the fingerprint or signature and checked against the person holding the passport.
The researchers are now working on a handheld, and instrument which could make unscrambling the hidden information easier.

We are going to talk again this week about higher education for disabled students who want to study in the United States．As we noted last time，there are no special colleges or universities for blind students．But there are for deaf students．One of them is Gallaudet University in Washington，D.C. Gallaudet is said to be the world’s only liberal arts university where everything is designed for deaf or hard-of-hearing students．About 2，000 students attend Gallaudet．The cost for international students is about 33,000 dollars a year．
Financial aid is available in the form of scholarships，but only after the first year of studies. Most scholarship aid goes to students in financial need who do well in their first year．One scholarship for international students is for deaf students from developing countries．Another is just for students from China．The university also offers an English Language Institute．But Gallaudet says this program does not guarantee (担保)acceptance to the university．
In the past year，students at Gallaudet protested against the administration’s choice of a new president for the university．The protests led to the choice of a different president who is more popular with the students，Robert Davila．He is a former officer of the National Technical Institute for the Deaf．This technical college is in Rochester, New York. It is one of the eight colleges in the Rochester Institute of Technology．
More than one thousand students attend the National Technical Institute for the Deaf. About one hundred of them are international students．They come from Africa, Asia，Europe and South America.
The cost is about 28,000 dollars a year for an international Technical Institute student．Foreign graduate students pay about 20,000 dollars. Both undergraduate and graduate student can receive limited financial aid. They can also take part in the student employment program．This program makes it possible for students to work at the school.

Public schools in New York，America’s biggest city, commonly have numbers for names．But this is unusual．In the United States，the process of naming a school often involves parents and the community
as well as elected school leaders.
Researchers say school names can show civic (市民的) values and also shape them． For example，naming a school after a historic person becomes a way to teach students about that person’s importance in history．
A new study examines the naming of American public schools．The study is from the Manhattan Institute，an organization that does public policy research．The study shows that fewer and fewer schools are being named after people．Instead。more schools are being named after the local areas or natural features like hills．trees or animals．The researchers say these changes raise questions about the civic duty of public education．
The looked at seven states with 20% of all public school students in the country. They found the similar result in every state: new school are less likely to be named after people. This is true especially with presidents. For example, in Arizona, public school in the past 20 years were almost fifty times more likely to be named after such things as landforms or plants .
School officials say they try to choose names that will not offend anyone. For example, a few years ago the city of New Orleans banned the naming of any school after a person who owned slaves. Other school system have rules against naming new schools after any person, living or dead .
The researchers say naming a school after a person can lead it important debates about democratic values. They call for more research to identify the causes and effects of the changes in school names.
The causes may include changes in American culture as well as in the political control of school systems. One area worth exploring , they say, is the link between trends in school names and weak results for public schools on measures of civic education.

The simplest way to say it is this：I believe in my mother．My 31 began when 1 was just a kid . I 32 be coming a doctor．
My mother was a domestic．Through her work，she observed that 33 people spent a lot more time reading than they 34 watching television．She announced that my brother and I 35 watch two to three pre—selected TV programs during the week． With our free time，we each had to read two books from the Detroit Public Library and 36 written book reports to her. She would mark them up with check marks and highlights．Years later we realized her marks were a 37 ．My mother was a domestic
When I entered high school I was a(n) 38 ，but not for long．I wanted the fancy clothes. I wanted to 39 the guys．I went from being an A -student to a B-student to a C-student. One night my mother came home from 40 her various jobs and I complained about not having enough Italian knit shirts. She said ,“Okay，I’ll give you all the money I make this week by scrubbing floors and cleaning bathrooms， and you can buy 41 food and pay the bills．With everything 42 ，you can have all the Italian knit shirts you want．”I was very 43 with that arrangement，but once I got through allocating money，there was 44 left．I realized my mother was a financial genius to be able to 45 our heads and any kind of food on the table， 46 buy clothes．I also realized that immediate satisfaction wasn’t going to get me anywhere. Success required intellectual preparation．I went back to my 47 and became an A-student again，and eventually I 48 my dream and became a doctor.
My story is really my mother’s story — a woman with 49 formal education or property who used her position as a parent to change the lives of many people around the globe. There is no job 50 than parenting．This I believe .
