In June this year, the BRICs, the world's newest economic
grouping, ended their fi rst major summit by calling for a
stable, predictable and more diversifi ed international
monetary system. But the leaders of Brazil, Russia, India
and China, stopped short of criticising the world's dominant
currency, the US dollar. The group repeated calls for a
bigger say in the global fi nancial system through greater
representation at major institutions, such as the World
Bank.

But the fi nal statement issued by the leaders made no
reference to developing new reserve currencies to challenge
the dollar, which Russia had called for at a separate event
earlier in the day.

Analysts say that as the global recession bites, the four Bric
nations are showing a growing willingness to work together.
One expert claimed the signifi cance of the summit would
be political rather than economic

The uses for oil
Oil is the largest source of liquid fuel and, in spite of attempts to develop synthetic fuels, world consumption of oil
products in increasing.
The oil industry is not much more than a hundred years old. It began when the first oil well was drilled in 1859. In the
early days, oil was used to light houses because there was no electricity and gas was very scarce. Later, people began to use oil
for heating too.
Most industries use machinery to make things. Every machine needs oil in order to run easily. Even a small clock or watch
needs a little oil from time to time.
The engines of many machines use oil fuels petrol, kerosene or diesel. Cars, buses, trucks, tractors, and small aircraft use
petroleum chemicals: synthetic rubber, plastics, synthetic fiber materials for clothes and for the home, paints, materials which
help to stop rust, photographic materials, soap and cleaning materials (detergents), drugs, fertilizers for farms and gardens, food
containers, and may others.
In 1900 the world’s oil production was less than 2 million tons a year. Today the oil industry is one of the world’s largest
and most important suppliers of raw materials.

If you think that there’s something oddly familiar about
descriptions of social media, it may be that you recall some of
the discussions in the 1990s about what the web would
become. And many of its emerging manifestations are close to
the idealistic imaginings from that time. A good way to think
about social media is that all of this is actually just about being
human beings. Sharing ideas, cooperating and collaborating to
create art, thinking and commerce, vigorous debate and
discourse, finding people who might be good friends, allies and
lovers – it’s what our species has built several civilisations on.
That’s why it is spreading so quickly, not because it’s great
shiny, whizzy new technology, but because it lets us be
ourselves – only more so. And it is in the “more so” that the
power of this revolution lies. People can find information,
inspiration, like-minded people, communities and collaborators
faster than ever before. New ideas, services, business models
and technologies emerge and evolve at dizzying speed in social
media.

How to dig out from the information avalanche
Majority of workers feel overwhelmed by deluge of data,
survey finds
By Eve Tahmincioglu
updated 8:18 p.m. ET March 16, 2008
Don't expect Shaun Osher, the CEO of Core Group
Marketing in New York, to answer your e-mail right away.
He has stopped responding to e-mails every minute and
only checks his e-mail account twice a day. He also started
turning off his BlackBerry during meetings.
This tactic has made him so much more productive
that earlier this year he held a meeting with his staff of 50
and "strongly suggested" that they stop relying so heavily
on e-mail and actually start calling clients on the phone.
And, he requested his employees put cell phones and
PDAs on silent mode during meetings, as well as curtail
the common practice of cc-ing everybody when sending
out an e-mail. "There was so much redundancy, so much
unnecessary work," he explains. "One person could handle
an issue that should take two minutes, but when an email
goes out and five people get cc-ed, then everybody
responds to it and there's a snowball effect."
It's not that Osher has anything against technology. In
fact, he loves it. The problem is, last year he realized he
was inundated with so many e-mails and so much
information in general that he began to experience data
overload. "In the beginning, e-mail and all this data was a
great phenomenon, revolutionizing what we do. But the
pendulum has swung way too much to the other side," he
maintains. "We're less productive."
Osher isn't the only one out there under a data
avalanche. Thanks to technological innovations, you can
be talking to a customer on your cell phone, answering a
LinkedIn invitation on your laptop, and responding to email
on your PDA all at the same time. Besides, during
tough economic times, who will want to miss any
information when your job could be on the line if you indulge
in the luxury of being offline? Turns out, seven out of 10
office workers in the United States feel overwhelmed by
information in the workplace, and more than two in five
say they are headed for a data "breaking point," according
to a recently released Workplace Productivity Survey.
Mike Walsh, CEO of LexisNexis U.S. Legal Markets,
says there are a host of reasons we're all on the information
brink: "exponential growth of the size of the information
'haystack,' the immensity and immediacy of digital
communications, and the fact that professionals are not
being provided with sufficient tools and training to help
them keep pace with the growing information burden."
Ellen Kossek, a professor from Michigan State, believes
we are less productive in this age of 24-7 technology, and
our multitasking mentality has spawned a "not-mentallypresent"
society. "We're becoming an attention-deficit
disorder society switching back and forth like crazy,"
Kossek says. "We're connected all the time. We're
working on planes, in coffee shops, working on the
weekends. Work is very seductive, but yet we're actually
less effective."
The key to getting your head above the data flood,
according to workplace experts, is managing and reducing
the information you're bombarded with.

          Green is the hot topic these days, and the concept
     is having an impact on the way people think about
     datacenters. Companies around the world are
     announcing ways to save energy and reduce costs by
5   buying new hardware and services. Yet, there is little
     guidance on how you can take action to control energy
     costs. In the past, electricity has been treated as an
     overhead expense, like the cost of space. But with rising
     power costs and issues regarding reliability, supply, and
10  capacity, electricity requires its own specific strategy.
          Projects regarding performance optimization and
     cost reduction are a part of everyday best practices in
     nearly every area of business. So why not treat energy
     cost in the same way?
15      As Information Technologies (IT) pros, many of us
     make decisions about the configuration and setup of
     servers, the specifications on the equipment our
     organizations purchase, and the requirements for
     datacenter upgrades and construction. We even provide
20  early design input during application development. When
     it comes to these projects, we obviously have a golden
     opportunity to be green and influence the energy
     efficiency of any datacenter.
          The first part of any strategy is to know your current
25  energy usage. You need to know where your energy is
     used and by what specific equipment, as well as what
     usage is efficient and what is wasteful in the datacenter.
     Unfortunately, it's rare to find power-consumption
     metering in place that can break down usage to a level
30  where people can see the results of their actions. Most
     organizations typically only see a monthly power bill
     that rolls up consumption into an overall bottom line.
     This offers little incentive for saving energy since
     individuals never see the impact of their decisions, and
35  there is no way for them to prove that their changes
     have actually saved energy.
          One of the first issues people confront when
     considering a green datacenter initiative is whether they
     have executive support. For the purpose of the article, I
40  am going to assume the answer is "not yet." Executive
     support requires a serious commitment that provides
     resources and budget for your initiative. And while there
     is a lot of talk about green datacenters, the reality is
     that there is still often a lack of serious support at the
45  executive level. If you did already have such executive
     support, you would probably be running a green
     datacenter right now.
          Still, even assuming you are not getting the support
     you need, there is a great deal you can do to push your
50  green datacenter initiative forward. So how do you
     determine effective actions to take in achieving your
     goals? Fortunately, energy efficiency is not a new
     concept and there is a lot that IT pros can learn from
     other industries. [.]
55      Anyway, for whichever direction you choose,
     planning an energy efficiency program for your datacenter
     will require collaboration across groups in IT. Until
     recently, the typical approach to planning IT solutions
     has been to ignore power costs early on during the design
60  phase, focusing on the hardware and software being
     purchased, along with the labor and hosting costs of
     the solution. When power is buried in the overhead cost
     of running solutions in a datacenter, energy efficiency
     is a low priority. Exposing the actual power being
65  consumed by solutions is the first critical step in changing
     the behavior of your organization.
