The Communication Revolution
The Communications Revolution
A look at the power of feedback in Web 2.0

Published 2009-04-24 11:29 (KST)
Many of today's online innovations deal directly with new ways to sort, organize, and filter the information and people with which we want to connect. Smarter "bridges" are popping up every day. Truly exciting stuff.
The introduction of Web 2.0 technologies into the enterprise greatly increases the value of your company's most important assets: employees, knowledge, relationships, and initiative.
Making knowledge more visible increases innovation and shortens turnaround times. Increased collaboration accelerates productivity.
Your company transforms into a more-socially connected organization that reacts faster and more effectively to the market.
Oracle Corporation said:
"Making Web 2.0 work for your enterprise is more than just deploying a one-off blog or wiki. Organizations will need to extend beyond to an array of custom social applications that improve productivity across many business processes and spur innovation throughout the enterprise."
The development and enhancement of what has been called Web 2.0 Internet is spectacular.
The concept of Web 2.0 is a way to encourage social networking and was initiated by the publisher Tim O 'Reilly.
The first developments remind us of some sites such as MySpace and Facebook, even in the field of videos YouTube.
Making Web 2.0 Work for Enterprise
Here are four tips to master the use of Web 2.0 and have higher productivity when using Internet.
There is at Internet new ways to communicate. After the revolution of Web 2.0 has appeared several tools you can use immediately. Indeed, there are at least four ways to communicate in this new globalized world. These forms are: Feevy, Twitter, Diigo and Thinkfree.
I'm not talking about the tools. I'm talking about the facility, the method, the way this could move.
I will first explain the use of Feevy.
This is a new service through which we can create our own "blogroll" of a dynamic manner. With this service you can add any blog to your web o to your blog or wiki.
If you want to experiment with this server then go to this link http://www.feevy.com/ and find a paragraph that says "get your feevy now"
Now I want to explain the use of Twitter.
Twitter's system, which limits messages to 140 characters, is used to broadcast both mundane and tantalizing information by a diverse group of users that include teenagers, celebrities, news agencies, politicians, police departments and companies. There are more than 6 million people with Twitter accounts, according to Twitter co-founder Biz Stone.
Think for a moment about the way we use Twitter, and the way that facility could change online interactions.
Four authors from the University of Maryland, Department of Computing, said:
"Twitter is a micro blogging and it is a new form of communication in which users can describe their current status in short posts distributed by instant messages, mobile phones, email or the web. Twitter, a popular microblogging tool has seen a lot of growth since it launched in October 2006 the Twitter's social network. We find that people use microblogging to talk about their daily activities and to seek or share information and connect with each other."
Some European newspapers already use this tool as the daily El Pais of Spain in its: http://twitter.com/el_pais
Twitter is the social network where anyone can search and find the affinity or need specific individuals and content to them go and meet. Twitter is a great medium for sharing ideas and getting instant feedback.
You can gather a range of opinions and constructive criticism within minutes, which can help enormously, whether you are planning a learning experience, writing a policy, or putting a job application together.
To make your own them you can go to Twitter: http://www.twitter.com/
And the Twitter Directory is: http://justtweetit.com/
Now I want to explain to communicate the potential of Diigo.
Diigo is a powerful research tool and a knowledge-sharing community.
When using the Diigo toolbar, you can see what other people have highlighted, and also comments (sticky notes) they added. That means that you are no longer limited to leaving comments on blogs, you can do so in any type of page
With this tool we can perform at one place and with our own browser, which needs to be done before with several applications.
In fact, we can add pages to a list of bookmarks on-line with export potential links in del.icio.us, furl spurl ... ... adding tags and categories for each link.
You can also select text on the web and save the page or article. Send some text to your own blog. Replace the action bar button for diigolet to do everything smoothly. Search in Google or other search engines with the same bar Diigo.
If you want to experience then do their own in Diigo: http://www.diigo.com/
Another interesting tool is Thinkfree, which you can write a paper, prepared PPS, using excel.
If you want to use this service the links is : http://www.thinkfree.com/
In brief:
Feevy is a dynamic blogroll that you can put in your blog or website by adding a simple html tag in the template.
Twitter and other micro interactions in social Media are changing the way we communicate and interact with one another.
Diigo is a social bookmarking website which allows signed-up users to bookmark and tag web pages. Additionally, it allows users to highlight any part of a webpage and attach sticky notes to specific highlights or to a whole page.

ETHANOL : MYTHS and FACTS
Ethaol: myths and facts
Myth: Ethanol production uses corn that would otherwise be used for human consumption.
Fact: Corn used for ethanol production is typically the corn that's used to feed livestock. And the production of ethanol provides for the production of distillers grains (DDG), which are used to feed livestock.
Moreover, these leftover grains contain a certain amount of fat. And with today's technology, that fat content can be raised or lowered depending upon the end use. For example, dairy cows and beef cattle require different amounts of fat in their diet to optimize production. The new technology allows ethanol producers to regulate the amount of corn oil present in their DDGs while simultaneously concentrating the amount of protein.
This means that not only are beef and dairy farmers able to acquire feed as an ethanol co-product, the feed they get can be tailored to their specific industry.
Myth: Ethanol harms car and truck engines.
Fact: Every major auto manufacturer approves the use of ethanol blends up to 10 percent under warranty. 10 percent is the most common mix found at today's gas stations. Cars built since the 1970s are fully compatible with a 10 percent mix (E-10).
Myth: It takes more energy to make ethanol than the fuel itself produces.
Fact: According to Michael Wang from the Energy Department-funded Argonne National Laboratory for Transportation Research, the energy used for each unit of ethanol produced has been reduced by about half since 1980. Today, 1 million BTUs of ethanol uses 0.74 million BTUs of fossil fuels (not including the solar energy used to grow corn). By contrast, he found that the delivery of 1 million BTUs of gasoline requires 1.23 million BTUs of fossil fuels.
Wang also noted in his study that energy balance value alone is not meaningful in evaluating the benefit of ethanol or any other energy product. For proper evaluation, a product's energy balance must be compared with that of the product it replaces. And compared to gasoline, any type of fuel ethanol substantially helps reduce fossil energy and petroleum use.
Myth: There's not enough land to grow crops for ethanol.
Fact: Former secretary of state George Schultz and ex-CIA director R. James Woolsey estimate that 30 million acres can replace half our gasoline demand. By taking land now used to grow export crops and instead planting energy crops, it's feasible to eliminate our need to import oil for gasoline.
Moreover, with advances in agricultural technology we can now harvest more corn using much less land.
This myth is also based primarily on corn, and doesn't take into account conventional celloulosic feedstocks such as switchgrass, corn stover and even old newspapers. These feedstocks can significantly decrease the amount of land needed to grow energy crops.
Myth: Switching to ethanol is expensive.
Fact: A new car can be made flex-fuel-capable for about $35. And the cost of adapting a retail gas pump for E85 is as little as $10,000.
Myth: Ethanol is unfairly subsidized.
Fact: Yes, ethanol producers and blenders share a 51-cent-a-gallon federal credit that costs taxpayers about $2 billion a year. Meanwhile, the US also directly subsidizes Big Oil. The General Accounting Office reports that the industry has netted $82 billion from just one line item alone, something called "excess of percentage over cost depletion," and there are many other such clauses. And this doesn't even get into the price tag of protecting shipping lanes to move the oil from point A to point B. The taxpayer picks that up as well.
La biotecnologia aplicada al sector agricola (Chile)
En Chile se ha avanzado en los últimos años en el campo de la investigación sobre BIOTECNOLOGIA aplicada a la agricultura. Hoy existen ese país firmas privadas que están compitiendo con firmas extranjeras y que están exportado sus productos a la Europa del Este y a otros países interesados en esas investigaciones.
En el link o enlace de arriba se puede leer, en la Hoja del Diario El Mercurio de Chile, la divulgación de estos avances científicos y sus logros prácticos.
