Business Week - December 5, 2007

It seems like everywhere you turn these days, a new
high-speed train is whisking more passengers across longer
distances faster than ever before. A [NOUN] to Paris from
London is quicker than flying; Japanese bullet trains traverse the
320 miles from Tokyo to Osaka in two and a half hours; and
magnetic levitating trains in Shanghai cut through the city at 268
miles per hour. But while high-speed trains may grab all the
glamour, the more mundane business of subway construction is
what's driving the biggest growth for transportation companies.
Indeed, the world is seeing an unprecedented boom in new
subways and expansion to existing systems. Thanks to surging
economic growth and urban populations, demand for subways is
soaring in China and India. Lots of other places around the
world also are building new lines, from Dubai to Santo Domingo,
capital of the Dominican Republic. And many European and
American cities ? including even such improbable locales as Los
Angeles and Phoenix ? have caught the transit bug.
Problem-Solving and Prestige
Some cities build out of necessity. Rising prosperity
prompted Dubai residents to buy so many cars that they realized
they could [ADVERB] longer drive these cars because they
were stuck in traffic. Others are keen on the environmental
benefits of metros, which produce far less pollution and
encourage drivers to leave cars at home. Some places, mainly
in the Middle East, are looking to diversify their oil-dependent
economies. And others, to be honest, are chasing an urban
status symbol. Building a metro won't turn any old town into
Paris or London, but it does tell the world that you've arrived.
"You have in some cases a prestige issue, which is more
the case in young cities in need of an image," says Jean-Noël
Debroise, vice-president for product and strategy at Alstom
(ALSO.PA), the French transport company that has built a
quarter of the world's metros.
Rennes is an example of the new trend. The city of about
212,000 people in northwestern France was looking to raise its profile when it installed a metro in 2002. It raised the bar by
opting for a driverless system made by Siemens ? just like the
shiny new No. 14 line in Paris ? protecting passengers from the
French penchant for transit strikes. Turin, Italy, did the same to
help win its bid for the 2006 Winter Olympics; its driverless
system opened just before the games. Even the Spanish island
of Mallorca inaugurated a short metro line in April in hopes of
luring even more tourists to its capital, Palma. Alas, it closed
indefinitely in September due to flooding, amid charges of
mismanagement.
A Boon for Transit Builders
The world's three largest metro manufacturers, Montrealbased
Bombardier (BBDB.TO), Alstom, and Munich-based
Siemens (SI) report high demand for mass transit, including
tramways and light-rail systems that run both under and
[PREPOSITION] ground. The global subway market was worth
9.3 billion dollars in 2005 and is projected to grow at a rate of
2.7% per year until 2015, according to a 2007 study by the
European Railway Industry Assn. Subway lines [TO BUILD] or
extended in 20 European cities and five Middle Eastern ones,
and dozens of towns are constructing light-rail systems, reports
the Brussels-based International Association of Public
Transport.
The size of a city determines its need for a metro system.
Cities of a few million people ? or those anticipating huge
population growth ? really can't do without a mass transit
system. But cities of one or two million inhabitants can choose
between a subway and a surface tramway, which costs far less
but also runs more slowly. [CONJUNCTION] funding is an issue,
cities usually will spring for a subway, says Debroise. "The
tramway has a very old image of the 19th century, with horses in
the streets," he says.

YOUTH PROLONGED: OLD AGE POSTPONED
by Robert Weale (King's College London, UK)
What exactly is human ageing? Can it be slowed down?
These questions have puzzled scientists and laymen alike
for generations, and continue to do so today. The author
addresses these thought-provoking issues by challenging
pre-conceived notions of age-perception, age-acceptance
and inter-age relations. Pertinent matters of age-related
communication are dealt with, and the reader is treated to
a grand tour of the latest theories of ageing, age-related
biological changes and age-related diseases, such as
Alzheimer's Disease. Here, the author's expertise in agerelated
eye diseases truly comes into its own.
Weale's unique work not only underlines important
genetic and avoidable risk factors but gives ample
consideration to possible consequences stemming from
different early lifestyles. Readers will re-consider their
ideas of what it means to age, and gain a better
understanding of what can and cannot slow down the
process of ageing.

1 Japan and Korea are outstanding markets in terms
of the world's advances in cellular telephony, where
multimedia applications have surged into feverish
4 popularity. Users in these countries have demanded
velocity and high quality data transmission - such as
images, videos and sounds - as the principal distinctive
7 features for the cellular telephone. Although the industry in
Brazil is not yet experiencing the same phase as in the
Asian countries, innovative third generation services,
10 aligned with world-class technology, are already present,
with data transmission speeds of up to 2.4 Mbps.
In fact, in some cases, Brazil has held multimedia
13 application launches simultaneously with the United States,
tremendously increasing the economic and digital inclusion
that cellular telephony has fomented in recent years. The
16 heavy impact of mobile communication on Brazilian
society can be measured by the expansion of the customer
base, which has been growing at historic rates of 30% a
19 year and now serves over 50 million customers. In other
words, four out of every ten Brazilians have a cellular
telephone.
22 The importance of mobile telephony has already
surpassed that of the traditional fixed telephone system,
because the cell phone actually fulfills the function of
25 taking communication to all levels of the population. Its
widespread network has opened gateways to regions that
formerly had not been benefited by the implementation of
28 a fixed telephone system, such as, for example, many rural
areas that are now mobile telephone customers.
The responsibility that cellular telephony carries
31 as an instrument for transforming people's lives tends to
increase enormously in the short term. In Brazil, third
generation CDMA 3G EVDO service is already offered and
34 is able to provide handheld resources, similar to CD, DVD
and TV, anywhere and at any time, based on Qualcomm's
cutting edge CDMA technology.
