WASHINGTON — Getting blood or other perishable supplies to an area that’s been struck by an earthquake or hurricane isn’t as simple as asking what brown can do for you. But a new model quickly determines the best routes and means for delivering humanitarian aid, even in situations where bridges are out or airport tarmacs are clogged with planes.
The research, presented February 18 at the annual meeting of the American Association for the Advancement of Science, could help get supplies to areas which have experienced natural disasters or help prepare for efficient distribution of vaccines when the flu hits.
Efficient supply chains have long been a goal of manufacturers, but transport in fragile networks — where supply, demand and delivery routes may be in extremely rapid flux — requires a different approach, said Anna Nagurney of the University of Massachusetts Amherst, who presented the new work. Rather than considering the shortest path from one place to another to maximize profit, her system aims for the cleanest path at minimum cost, while capturing factors such as the perishability of the product and the uncertainty of supply routes. ‘You don’t know where demand is, so it’s tricky,’ said Nagurney. ‘It’s a multicriteria decision-making problem.’
By calculating the total cost associated with each link in a network, accounting for congestion and incorporating penalties for time and products that are lost, the computer model calculates the best supply chain in situations where standard routes may be disrupted.
‘Mathematical tools are essential to develop formal means to predict, and to respond to, such critical perturbations,’ said Iain Couzin of Princeton University, who uses similar computational tools to study collective animal behavior. ‘This is particularly important where response must be rapid and effective, such as during disaster scenarios … or during epidemics or breaches of national security.
’ The work can be applied to immediate, pressing situations, such as getting blood, food or medication to a disaster site, or to longer-term problems such as determining the best locations for manufacturing flu vaccines. . Retrieved April 7th, 2011.
According to the text, judge the following items.
If “ticked off” (l.24) and “spinning” (l.25) were replaced respectively by marked off and rotating, there would occur no grammar mistakes in the sentence.
éOur latest tips tell you how to make Microsoft Office 2010's word
processor and spreadsheet apps perform some handy tricks that
Microsoft has documented poorly.
By Edward Mendelson
PCMag.com's Microsoft Office 2010 tips collection
continues, this time with ten tips for Word and Excel users. Most
of these tips are fairly straightforward, and most apply to the
most recent versions of Office. Some of them, however, offer
new twists for the latest version of Office. Expert users will be
familiar with some of these ten tips, but we hope that any user
will find at least a few of these to be useful.
What kind of tips am I talking about this time? Finding
ways to perform poorly documented functions in Word and
Excel. One of these tips, for example, tells you what to do when
Word inserts a horizontal line across the page when you only
wanted to type a few dashes. In the past few months, everyone
in my family has tried and failed to wrestle an unwanted
horizontal line out of a Word document. It might not sound like a
big issue, but once you've got it in your document, good luck
finding help from Microsoft on how to get rid of it.
Some software vendors, like Adobe, continue to provide
help systems that work like improved versions of traditional
software manuals. In those apps, every menu item, every
toolbar icon, is carefully explained, and with a little patience you
can find all the information you need. Microsoft,
provides you with a kind of information supermarket, with huge essays
about topics you don't care about, dozens of selections when
you only need one, and no consistent way to find the information
you want.
Combine Portrait and Landscape Pages in a Word Document
Microsoft Word expects you to organize your documents
in a highly-structured but not very intuitive way. If you want to
format most of a document in portrait mode, but one or two
pages in landscape, you
simply change the orientation of the current page. Instead you need to insert a section break
before and after the text you want to format in landscape mode,
and then apply landscape orientation to the section that you
created. Place the insertion point at the point where you want
landscape orientation to begin. On the Page Layout tab, choose
Breaks, then, under Section Breaks, choose New Page. Then
move the insertion point to the end of the text you want to format
in landscape, and insert the same kind of break. Then put the
insertion point anywhere between the two breaks; return to the
Page Layout tab, and click the down-pointing arrow at the lower
right of the Page Setup group. In the Page Setup dialog, on the
Margins tab, select Landscape orientation, then go to the "Apply
to" dropdown and select This Section.

'CityVille' now bigger on Facebook than 'FarmVille'
(Mashable) -- Facebook game developer Zynga has proved once
again that it knows exactly what it needs to do to keep millions of
Facebook users happy and occupied.
In less than a month, its latest game "CityVille"___ ______
(become) the most popular application on Facebook, surpassing
Zynga's previous hit "FarmVille" in all areas.
According to AppData, "CityVille" now has 16.8 million daily
active users, compared to "FarmVille's" 16.4 million. Looking at
monthly active users, "CityVille" is also ahead with 61.7 million
users, while "FarmVille" trails behind with 56.8 million users.
Zynga's "FrontierVille" and "Texas HoldEm Poker" also round out
the top five: put those four apps together (we'll disregard the fact
that many of those users overlap for a second) and you have a
very impressive number: 184 million active users across four
games.
The only non-Zynga app in the top five list is "Phrases," _____ at
one point threatened to take the top place, but is now
overshadowed by both "CityVille" and "FarmVille."
"CityVille's" future success wasn't hard to predict after an
amazingly good start at the beginning of December, but it's still
impressive to see Zynga amassing tens of millions of users in a
matter of days, proving that all that venture capital that went into
the company isn't there by accident.

The Role of Museums in Education
Museums provide knowledge and inspiration, while also connecting communities. At a time of economic recovery, and in the run-up to the Olympics, they are more important than ever. Museums and galleries deliver world-class public services which offer individuals and families free and inspiring places to visit and things to do. Museums attract audiences from home and abroad. Museums provide the places and resources to which people turn for information and learning. They care for the legacy of the past while creating a legacy for the future.
Museums are uniquely egalitarian spaces. Whether you are rich, poor, or uniquely-abled, the museum door is always an open welcome. A sense of history and beauty, gifts from our cultural heritage, inspires the ordinary soul into extraordinary possibilities. They bind communities together, giving them heart, hope and resilience. They make a vital contribution to international relations and play a unique role in fostering international cultural exchange. If life was just about earning to eat, we'd be depleted and tired. Museums bring to life the opportunity to experience meaning beyond the mundane. Museums make the soul sing!
The most visible and expected offerings of a museum are its exhibitions. Exhibitions tell stories through objects. In a world where virtual experiences are ever increasing, museums provide tangible encounters with real objects.
What does looking at a crystal clear specimen of beryl, a vertebrate fossil emerging from its plaster jacket, or the flag that flew over Inge Lehman's seismological observatory provide in an educational sense? Some professionals maintain that the visceral reaction of wonder, awe or curiosity – the affective response of the viewer – is the enduring legacy of a museum visit. It opens the door to the visitor's mind, engaging them in a discipline that perhaps failed to interest them through other means, and might inspire them to learn more. Furthermore, the social context of a museum visit, where exploration occurs in a friendly atmosphere without the pressure of tests and grades, helps keep that door open.
Curators and educators also aspire to engage the rational mind of the viewer. A mineral collected in the field and displayed in the museum is out of its original context, but thoughtful juxtaposition of the mineral with other objects helps the visitor make new connections. Exhibit labels or a knowledgeable docent leading a tour not only inform directly, but also guide visitors in making their own observations of the object. Hands-on displays combined with objects can provide forceful connections – an “aha!” experience for the visitor. Alan J. Friedman, the former director of the New York Hall of Science, recounts a watershed experience during a 1970 museum visit in which a model telescope that the could touch and adjust brought to life the meaning of the antique telescope.
Museums are the world's great learning resource – they introduce new subjects, bring them alive and give them meaning. Learning in museums improves confidence and attainment: it also opens us to the views of our fellow citizens. Museum collections and the knowledge of museum professionals inspire learning. As the world around us changes, museums and galleries promote awareness of the critical questions of place, humanity, science and innovation.

A música “Hunting High and Low” foi um dos grandes sucessos da banda norueguesa A-ha na década de 80. Leia a letra da canção e responda a questão.
Hunting High and low
(Paul Waaktaar-Savoy)
Here I am
And within the reach of my hands
She sounds asleep
And she's sweeter now
Than my wildest dream
Could have seen her.
And I watch her sleeping away
But I know I'll be
Hunting high and low
Ah, there's no end
To the lengths I'll go to
Find her again
Upon this my dreams are depending
Through the dark
I sense the pounding of her heart
Next to mine
She's the sweetest love
I could find
So I guess I'll be
Hunting high and low
Do you know what it means
To love you
I'm hunting high and low
And now she's telling me
She's got to go away
I'll always be hunting high and low
Only for you
Watch me tearing myself to pieces,
Oh, for you I'll be hunting high and low

TEXT 2
I do realize that in the world of technology there are early and late adopters. I’m not the earliest of cutting-edge early TESL adopters, but I do like to try out new technology and incorporate it into my teaching. This list is a handful of technologies that are established enough not to be too problematic, user-friendly enough that just about anyone can start using them quickly, and useful enough that you’ll soon wonder how you got along without them. In short, this is a list of tech that just about everyone can (and maybe even should) be using in 2010.
1. Wikipedia – It has become popular to question its accuracy. Wikipedia has become a real knowledge bank on the internet. Once we figure out what it is (a compilation of all referenced knowledge) many of these criticisms fall down. Access to all this information means a reorganization of learning.
2. Google – No, I don’t just mean search, but all the other stuff: maps, docs, calendar, etc. It’s never been so easy to collaborate with other people.
3. Twitter – A year ago, I taught a course through Twitter with mixed results. This microblog is almost exclusively interactive, but my ESL students found it tough to collaborate within Twitter because of its constraints on length. The email by contrast, is very simple – it is equally interactive but it is constraint free. So, you should use it and you should see interesting results !
Can you learn the language by using the above alone? Of course not! But they are a good springboard and I hope they lead you to discover all other media available out there (ebooks, blogs, YouTube videos, music, movies, etc.).
More web in the pipeline. Please post a comment.

Answer question according to TEXT 1 below, adapted from http://news.bbc.co.uk/2/hi/americas/8606466.stm (accessed on April 7th, 2010) .
TEXT 1
At least 200 people have died in the Brazilian state of Rio de Janeiro after another storm. This is arguably the worst torrential rain for decades, causing flooding and landslides. Our website readers in Rio de Janeiro have been sharing their experiences.
Comment 1 - I’ve never seen such chaos. We weren’t prepared for this, even though we were warned that a big storm was about to come. Newspapers are saying that the reason for the catastrophe is the garbage. Well it may have been. We need to teach recycling at schools and community groups, otherwise we will have more disasters like this. (Lia, Niterói)
Comment 2 - Today I witnessed Rio de Janeiro on the brink of collapse. I ventured out around midday, just as the electric power blacked out in my neighbourhood. Three hours later, looking out of my office window, the city still reminded me of a war zone. “What´ve we done to deserve this?”, I thought. It’s night time now and I haven’t been able to return home. I might do so tomorrow. (José, Rio)
Comment 3 - Worldwide, we are seeing more and more
climate instability. The deserts of central Asia are growing,
while areas of the US (and now Rio) are drenched. The lakes
in Minnesota have never thawed this early, at any time in the
recorded record. The icecaps will be history, and islands
around the world are disappearing under the surf. The oceans
are warming, the coral reefs are dying. How much more
evidence do we need of global warming? (João, Brasília)
