key lesson for students in Dr

Yu-Hung Hong這 course on Hong

Kong

s land and environmen~al policy. Not

believing everything you read was the

second.

I challenged my students to examine arguments;' said Dr Hong, an assistant

professor in the Division of Social Science.

"Are there data to back up the statements?”

This lesson sparked an innovative final

project for which public housing estates

became laboratories for learning: In the d巴bateon the government法 twice

failed scheme to sell public rental flats to tenants, newspapers have aired government explanations, the views of 翱詔c_.:為

individual tenants and the results 區

of different surveys of tenants' opinions.

A close look at' the surveys

, however, reveals certain biases and

raises doubts about their reliabil-1ty. To date, opinion surveys have been conducted by political

parties. Their methods have

included handing out

question-na1Ies at mass meetings; or to

passersby near the estate.

tenants across the seven estates said their

primary motivation was a concern that

government wo叫dincrease th_eir rents in the future, reflecting doubts about the

govern-ment's motives in launching the scheme.

Other reasons for buying include, in order of importance: location;lower selling

prices of public units than private flats;and

a sense of belonging to the community. Survey results contrast with the

govern-ment's own explanations for the failure of the

PRFS scheme when it was launched in 1991

and 1992. Each time, the government

withdrew the scheme, saying tenants did not support it because prices were too high and the resale restrictions were too tight.

﹒ 扭扭

The problem with these

methods is you don

t know if

opinions are representative;' Dr

Hong said.

People who would

attend a meeting might have a pre-fixed opinion. Most tend to be

angry.

A group of students decided to

A Stanley Chan Wing Ho, E;ric Cheung Wang Fu呵, Leung

Kin San·g, Eunice Chu Yeuk Ying, Barry Lo Wing Kin;Jeff

Wong Ki Heng, Eddy Lai Vat Ku and Chark Cheung Kwan Fai surveyed the King Lam Estate in Tseung Kwan O for

their final project in their land and environmental

policies course. find out for themselves what public housing

tenants thought of the Public Rental Flat Selling sch巴me,OT PRFS.

Wi出 DrHong's guidance, the 62 under graduates designed a questionnaire, randomly chose 5% of the households at seven public estates and then knocked on doors to ask tenants for their views.

The ·survey of 1,350 tenants was conducted during the spring break. It was

harder work than an}rone had anticipated.

"About 40% of the targeted tenants refused to participate," Dr Hong said,

making it difficult for. the students to get representative opinions.

Perseverance paid off with surpr心ing

results.

Students found that a m句orityof tenants

can a在ordto buy their flats and would if the government gave them low-interest,

long-term loans.

When asked why they would buy a fl哎,

“Pur℃hasing property as an investment

is the least important factor among all

considerations;' said Dr Hong, who com

piled the students' findings into a report sent

to the Housing Branch,“.'Our hunch is people

want a stable level of rent. People on fixed

incomes cannot save for the future when

their housing costs 50% ormore of their monthly salary, which is the case for most people in Hong Kong."

Both the process and .the end results of

the students' work were of value.

The government welcomed the rigorous 、

research methods which resulted in more i·epresentative, reliable and useful data.

The students appreciated the learning process. Godfrey Li Yiu Man (IEEM) put it succinctly:“I have learned to research, to put

together a questionnaire and interview

people and. present the findings. I couldn

Systems Librarian at the University Libra 吵, has

browsed the cybershelves for this issue.

Online bookstores come in different

forms. Some are publishers selling their own titles, while some .are run by e泊sting

bookstores as an alternative sales outlet. The largest tend to be exclusively

Web-based with little in-house inventory,

instead relying on publisher and distribu-tor stocks.

Amazon Books (htψ://amazon.com/)

is the most sophisticated on line bookstore

in the world, with over 2.5 million titles.

Books are reviewed online or you can

browse suggestions from the New York

Times Book Review or Oprah's Book Club. The site has an advanced search

facil-ity. Amazon also offers an online alerting

service, so you can get regular emails announcing new books in your areas of

interest. Prices are often heavily

dis-counted, especially compared to Hong Kong prices.

For Chinese language materials visit

CBC [全球華人閱禎網絡l at http://www.

chinesebooks.net/. The site carries over 100,000 titles from publishers)n Taiwan,

Hong Kong and the Chinese Mainland;

including some local university presses.

For books in German, Spanish and

Dutch· try Bookserve (http':l/www.

bookserve.com). Although access is slow,

their selection is quite good.

Ordering by credit card is pretty safe,

but if you feel uneasy you can usually send

a fax or money order instead.

Books shipped by air cost as much as

STUDENT FOCUS

Campers Taste University Life

T

he average age on campus dropped in July with 520 local school

. students attending summer camps in engineering, biology, chem

istry an.d physics.

Form 5 and 6 science students sampled university life as well as

stud-ies. Activities ranged froni tree walks for biologists to astronomy nights

for would-be physicists.

Swnmer camps began

at UST in 1995. This year

saw the first camps in biology and chemistry.

For its first camp,

Biology selected 50 Form

5 students. The campers

worked in the labs for a

week with a special

reward in mind. The top five students were offered

internships with the department's researchers

this month.

"Of that original camp, 30 % are now UST students;' said

Dr Helen Shen, associate dean of engineering. "Our camp

introduces UST--:--and engineering- to some of the brightest

students in Hong Kong.

"Medicine and business are a big attraction for these

students;' Dr Shen said. "As few high school teachers have

engineering backgrounds, we may be their only information

source on engineering:'

This year, the School also involved the campers' parents,

treating them to talks, lunch and a tour of facilities. "The

feedback was good;' Dr Shen said. "Parents welcomed the

event-and our vision for their children as competent,

competitive graduates:'

Physics welcomed 166

Form 6 campers during

three separate camps. The

department estimated that between half and a third of

current students were

camp alumni.

• A bamboo oil rig takes the strain during testing for the engineering design challenge.

"Of

that

originar

camp,

"This is the first time that secondary students

have participated in cutting-edge i'esearch at

university level;' said Dr Albert Yu of Biology,

organizer of the intern program.

"It's a myth that secondary students can't do research. They just need the right opportunity, facilities1and inspiration."

30% are now

UST

students.

in Hong Kong."

"The students don't get a chance at high

school to do the experiments we offer during

the camp. They enjoy the challenge;' said Dr

Tam Wing Yim, camp di.rector.

Dr Leung and his colleagues put together an

academic program oflab sessions, quizzes and careers talks for 130 Form

6 campers, while the Chemistry Students Society helped out with a social

program that explored the elements in a different way, with camp fires in

the Atrium and water wars outside the halls.

Engineering and Physics were the pioneer camps in 1995. Three years

on, they are still committed to the format, with Engineering organizing

the largest camp of the summer-175 Form 6 students in all.

This year, Physics split the camp.into three sessions, allowing smaller

groups and better use of resources. "Running· one camp is a waste of

resources;' said Dr 'ram. "We can cover more schools with this format."

Expect a Physics camp next year too. "If there is support we'll carry

on;' said Dr Tam. "Maybe there could be a camp for the whole of the School of Science."

Crime Solving in the Biology Lab

From O.J. to the X Files, DNA fingerprinting has changed the face

of forensic investigation .. Biology's summer campers got the

chance to try it out first hand.

With test kits donated by US company BioRad, the students

helped to identify the perpetrator by processing DNA from a

mythical crime scene and comparing it with six 'suspect' samples.

• Campers prepare the DNA samples for fingerprinting.

"Fingerprinting is a hot topic in genetic diagnosis and forensfc studies;' said Dr King Chow of Biology. "Students read about it in the papers and now they've had a chance to do it themselves:'

The workshop exposed students to the technique and its

applications. Dr Chow pointed out that many students in the A

Level biology stream were aiming for medical school and other

life science professions.

"We need to convince them that biology covers topics wider

than they can imagine, and to choose after examining the subject

and their own interests more closely;' said Dr Chow. "These

experiments show them what biology can offer."

Engineering a Future Career

·

Cathy Chiu Wing Chong, a Form 6 student from Carmel Park View

Secondary School, wants to be a civil engineer. "It would be great

to construct buildings and railways;' she said.

Cathy was.one of 75 female campers invited to the School of

Engineering's women-only banquet. During the evening, they met

role models-women engineers, faculty and current students-who demonstrated that engineering was a smart choice for women.

"If you want to attract the-best people to the profession, you ·

can't ignore 50% of

the population;' said

Ir Christine Wong,

Chair of the Hong

Kong Institution of

Engineers Young

Members

Commit-tee, and the evening's keynote speaker.

"Women may think harder before

choosing

engineer-ing, but those who

are committed have a

successful and

enjoyable career."

Dr Helen Shen agrees. "Our women

engineering students

do very well bu~ only

make up 11 % of our

students. We want to

increase that

percent-age and the banquet.

is the first step:'

• Not just for the boys: girls made up nearly one third of this year's camp.

Q

The opening of Wendy's and the Congee counter in the LG5 Food Court is good news; we now have more choices. But they're not environmentally friendly ones. The Congee counter uses disposable plastic utensils instead of durable ones. Is this a tempo-rary arrangement only?

A

Stanley Sit (CSO): "The operator of the LG5 Congee Counter has

· already orde(ed durable bowls, plates, spoons, etc., for dine-ih use. The use of disposable ware is just a temporary arrangement and the dis
