Last Chance to Apply for 2013 Elk Hunts in Kentucky ? Land of 10,000 Elk.

Kentucky Department Fish Wildlife

Anderson County, KY --(Ammoland.com)- Frankfort, KY ?-(Ammoland.com)- Kentucky Department of Fish & Wildlife will draw 1,000 applicants in early May to hunt the largest elk herd east of the Rockies this fall. Hunters must apply online by April 30th (midnight Eastern time) to enter the random drawing for 2013 elk permits. Entries are only $10 each.

Kentucky offers a variety of elk hunting opportunities, and seasons run from September through December. Applicants may apply for 2 of 4 permit types: firearm bull, archery bull, firearm cow, and archery cow. Crossbows may be used with archery permits during designated timeframes. Those age 15 and under may also apply for 10 youth, bull/cow permits.

Elk hunter success is about 70% in Kentucky. The number of permits available has steadily increased since the hunt?s inception in 2001, beginning with just 12 permits. For those drawn, hunting license plus elk permit cost $495 for nonresidents and $50 for residents. Hunters may bring along as many helpers as desired. Last year?s odds of being drawn and more details are posted at fw.ky.gov.

The elk hunt is held in 16 southeastern counties that occupy 4.2 million acres?much bigger than Yellowstone National Park. There are 574,000 acres of public land in the elk hunt area, along with ample private land. Private guide/outfitter services are also available.

Kentucky?s elk restoration program is one of modern wildlife management?s greatest success stories. Elk were extirpated in Kentucky by the early 1800s. Elk restocking began in 1997 with the release of 7 animals. A total of 1,554 elk were reintroduced in Kentucky by 2002, with animals provided by 6 western states having healthy elk populations. Within 10 years, the population reached the target of 10,000.

Those interested in the hunt should apply now. The deadline is midnight April 30. Don?t allow last minute Internet problems or unexpected diversions to keep you from the hunt of a lifetime in the ?Happy Hunting Ground? that is Kentucky!

Kloudless Launches Service That Uses Connectors To Move Files Between Different Cloud Services

Kloudless launched at Disrupt NY 2013 today with its service for moving?data from email to different cloud platforms through connectors which act like pipes that flow between the different services. The service offers a plugin that the user installs in Outlook or as an extension through their web browser to use in Gmail or other apps, said CEO Eliot Sun. Kloudless does not store any data, nor files, the service sits in the middle, acting basically as just a pipeline. When looking at Kloudless, think of services such as ifttt but with less automation and more ability to customize how data flows out of email and into other services. The idea is to give people more flexibility when moving data. It may be that you want some ways to customize the data when pulling into Salesforce.com or some other app. It?pulls data on-demand from one cloud service to another. For example,?Sun said it has the capability to pull in data points from an analytics tool to a discussion in a service such a Yammer. Venture Capitalist Tim Draper and Yammer Co-Founder David Sacks liked the idea so much that they put a seed investment into the company. So far the company has raised $889,000.?They believe that Kloudless can be a wedge in the market, offering the automation and the flexibility that companies need. Plus, it provides a level of data governance that can be developed with more customized solutions.?There may be integrations that a company standardizes for reasons of compliance but also gives freedom in other ways that an automated system can’t offer. Kloudless is, in technical parlance, a “message bus” for the cloud. The message bus is a permanent layer, an intricate event-based system — a middleware essentially. Every event, every request, goes through the message bus. The data gets normalized and sent to the right place, in the right context.?Companies such as Tibco have made a fortune selling message bus technology. Other companies like Tibco, Mulesoft and SnapLogic?provide top down systems. Kloudless provides a bottom-up approach. It’s both a consumer type app and for managers, team leaders, and IT to provide dashboards for better visibility into data ownership/workflow and the ability to set cross-application policies. Kloudless uses a consumer enterprise style pricing. It’s free with limited features. Pricing starts at $3 a month.?It uses its foundation as an email platform to network. The idea is to build enough

Protein shaped like a spider

Monday, April 29, 2013

The protein C4BP is similar to a spider in its spatial form with eight "arms". The structure of the "spider body" has recently been described in detail by researchers from the Helmholtz Centre for Infection Research (HZI) in Braunschweig and the Technische Universit?t Darmstadt. This leads the scientists to unconventional ideas ? the protein is possibly suitable as a scaffold for the transport of active pharmaceutical substances, particularly biomolecules. The researchers are publishing their results in the current edition of the international journal Journal of Molecular Biology.

The so-called complement system is a part of the innate immune defence within the human body: more than sixty different proteins form one of the first countermeasures against invading pathogens. One of them is the C4b binding protein known as C4BP. It is involved in the immune defence against bacteria in the blood. How precisely such protein substance carries out its function or how it interacts with other molecules ? this can only be predicted by scientists once they have identified the spatial structure of the molecule. Structural biologists therefore examine the substance in its purest form with x-ray machines and are able to reconstruct the spatial design in a computer. Regarding the case of the recently-described C4BP, they found out that it has eight "arms" and thus resembles a spider to a certain degree. Seven of the "arms" are identical as "alpha chains", while the eighth, a "beta chain" is different from the others. The spider body that holds these side chains together is called the oligomerisation domain. Its structure was of special interest to researchers, since it determines the spatial alignment of the "arms".

The newly-described structure allows two possible variants. "However, there is one of these two possibilities that is more feasible because it is much more stable", says Thomas Hofmeyer, PhD student at the Institute for Organic Chemistry and Biochemistry of TU Darmstadt and first author for the publication. And the C4BP is quite stable, as explained by the other first author Dr. Stefan Schmelz from the Department of Molecular Structural Biology of HZI: "Even boiling is not able to break down its form." Usually, human proteins remain stable up to about 40?C. Higher temperatures are of course not found in the body, but the stability of C4BP has a completely different purpose: "As is the case with all components of the complement system, the C4b binding protein is present in blood plasma. The proteins are exposed to enormous shear forces in the blood stream", explains Dr. Andrea Scrima, head of the junior research group "Structural Biology of Autophagy" at HZI. Therefore, the protein needs a high stability in order to be able to withstand these forces.

The researchers now would like to make use of the spatial structure. Their discoveries have facilitated biochemical synthesis of the molecule. In the context of replication within a test tube, the researchers can undertake alterations in a targeted way: "Instead of the seven alpha chains, we could implement other biomolecules", claims Prof. Harald Kolmar, director of the work group Applied Biochemistry at the Institute for Organic Chemistry and Biochemistry at the Technische Universit?t Darmstadt. "We can use the oligomerisation domain as a framework, in order to decorate it with drug molecules." These could be vaccines, for example. Seven with one stroke, by means of the seven-fold binding capability. Bundled in this manner, more active ingredient could make its way to its target. The dosage could be reduced but the immune system would still be considerably stimulated. "It is thereby possible in the future that bottlenecks, limiting the supply of vaccine, could be avoided and side effects reduced", says Kolmar.

NewsRel Uses Machine Learning To Summarize News Stories And Put Them On A Map

After 24 hours of staring at their screens, the teams that participated in our?Disrupt NY 2013?Hackathon?have now finished their projects?and are currently presenting them onstage. With more than 160 hacks, there are far too many cool ones to write about, but one that stood out to me was NewsRel, an iPad-based news app that uses machine-learning techniques to understand how news stories relate to one other. The app uses Google Maps as its main interface and automatically decides which location is most appropriate for any given story. The app currently uses Reuters‘ RSS feed and analyzes the stories, looking for clusters of related stories and then puts them on the map. Say you are looking at a story about the Boston Marathon bombings. The app, of course, will show you a number of news stories about it clustered around Boston, then maybe something about the president’s comments about it from Washington and another article that relates it to the massacre during the Munich Olympics in 1972. In addition to this, the team built an algorithm that picks the most important sentences from each story to summarize it for you. As you scroll through the stories, the app always recalculates the related stories on the fly, too, which makes for a pretty interesting news-reading experience. Besides the map, the team also decided to develop the user interface around gestures, so you swipe down to read the full story on the news service’s webpage and you can swipe left and right to scroll from one story to the next The team members have a background in machine learning and iOS engineering. They met during their undergrad studies a few years ago and decided to team up for the hackathon. They told me that they plan to keep working on the app and release it in the near future.

Breitling Releases The Emergency II, A Watch That Can Save You If You're Trapped On The Island

If trapped on a deserted island, you may want to spend months looking for the Pearl Station and figuring out the smoke monster, you could just pull the antenna out of the Breitling Emergency II and call in a rescue party. The original Emergency watch, designed in the 1990s, sent 121.5 MHz signal that could be heard by rescue craft within 100 miles of the watch. The new model also transmits at 406.04 MHz, a frequency that is now monitored by orbiting satellite. The watch can transmit for about 24 hours before the battery dies.

Plants moderate climate warming

Apr. 28, 2013 ? As temperatures warm, plants release gases that help form clouds and cool the atmosphere, according to research from IIASA and the University of Helsinki.

The new study, published in Nature Geoscience, identified a negative feedback loop in which higher temperatures lead to an increase in concentrations of natural aerosols that have a cooling effect on the atmosphere.

"Plants, by reacting to changes in temperature, also moderate these changes," says IIASA and University of Helsinki researcher Pauli Paasonen, who led the study.

Scientists had known that some aerosols -- particles that float in the atmosphere -- cool the climate as they reflect sunlight and form cloud droplets, which reflect sunlight efficiently. Aerosol particles come from many sources, including human emissions. But the effect of so-called biogenic aerosol -- particulate matter that originates from plants -- had been less well understood. Plants release gases that, after atmospheric oxidation, tend to stick to aerosol particles, growing them into the larger-sized particles that reflect sunlight and also serve as the basis for cloud droplets. The new study showed that as temperatures warm and plants consequently release more of these gases, the concentrations of particles active in cloud formation increase.

"Everyone knows the scent of the forest," says Ari Asmi, University of Helsinki researcher who also worked on the study. "That scent is made up of these gases." While previous research had predicted the feedback effect, until now nobody had been able to prove its existence except for case studies limited to single sites and short time periods. The new study showed that the effect occurs over the long-term in continental size scales.

The effect of enhanced plant gas emissions on climate is small on a global scale -- only countering approximately 1 percent of climate warming, the study suggested. "This does not save us from climate warming," says Paasonen. However, he says, "Aerosol effects on climate are one of the main uncertainties in climate models. Understanding this mechanism could help us reduce those uncertainties and make the models better."

The study also showed that the effect was much larger on a regional scale, counteracting possibly up to 30% of warming in more rural, forested areas where anthropogenic emissions of aerosols were much lower in comparison to the natural aerosols. That means that especially in places like Finland, Siberia, and Canada this feedback loop may reduce warming substantially.

The researchers collected data at 11 different sites around the world, measuring the concentrations of aerosol particles in the atmosphere, along with the concentrations of plant gases, the temperature, and reanalysis estimates for the height of the boundary layer, which turned out to be a key variable. The boundary layer refers to the layer of air closest to the Earth, in which gases and particles mix effectively. The height of that layer changes with weather. Paasonen says, "One of the reasons that this phenomenon was not discovered earlier was because these estimates for boundary layer height are very difficult to do. Only recently have the reanalysis estimates been improved to where they can be taken as representative of reality."

Millions in CIA "ghost money" paid to Afghan president's office: New York Times

(Reuters) - Tens of millions of U.S. dollars in cash were delivered by the CIA in suitcases, backpacks and plastic shopping bags to the office of Afghanistan President Hamid Karzai for more than a decade, according to the New York Times, citing current and former advisers to the Afghan leader.

The so-called "ghost money" was meant to buy influence for the Central Intelligence Agency (CIA) but instead fuelled corruption and empowered warlords, undermining Washington's exit strategy from Afghanistan, the newspaper quoted U.S. officials as saying.

"The biggest source of corruption in Afghanistan", one American official said, "was the United States."

The CIA declined to comment on the report and the U.S. State Department did not immediately comment. The New York Times did not publish any comment from Karzai or his office.

"We called it ?ghost money'," Khalil Roman, who served as Karzai's chief of staff from 2002 until 2005, told the New York Times. "It came in secret and it left in secret."

For more than a decade the cash was dropped off every month or so at the Afghan president's office, the newspaper said.

Handing out cash has been standard procedure for the CIA in Afghanistan since the start of the war.

The cash payments to the president's office do not appear to be subject to oversight and restrictions placed on official American aid to the country or the CIA's formal assistance programs, like financing Afghan intelligence agencies, and do not appear to violate U.S. laws, said the New York Times.

There was no evidence that Karzai personally received any of the money, Afghan officials told the newspaper. The cash was handled by his National Security Council, it added.

U.S. and Afghan officials familiar with the payments were quoted as saying that the main goal in providing the cash was to maintain access to Karzai and his inner circle and to guarantee the CIA's influence at the presidential palace, which wields tremendous power in Afghanistan's highly centralized government.

Much of the money went to warlords and politicians, many with ties to the drug trade and in some cases the Taliban, the New York Times said. U.S. and Afghan officials were quoted as saying the CIA supported the same patronage networks that U.S. diplomats and law enforcement agents struggled to dismantle, leaving the government in the grip of organized crime.

In 2010, Karzai said his office received cash in bags from Iran, but that it was a transparent form of aid that helped cover expenses at the presidential palace. He said at the time that the United States made similar payments.

The latest New York Times report said much of the Iranian cash, like the CIA money, went to pay warlords and politicians.

For most of Karzai's 11-year reign, there has been little interest in anti-corruption in the army or police. The country's two most powerful institutions receive billions of dollars from donors annually but struggle just to recruit and maintain a force bled by high rates of desertion.

Syrian rebels, troops clash at 3 air bases

BEIRUT (AP) ? Syrian rebels seeking to topple President Bashar Assad fought intense battles with his troops on Sunday to try to seize control of three military air bases in the country's north and curtail the regime's use of its punishing air power, activists said.

Rebels, who have been trying to capture the air fields for months, broke into the sprawling Abu Zuhour air base in northwestern Idlib province and Kweiras base in the Aleppo province on Saturday. Fighting raged inside the two facilities Sunday.

The Britain-based Syrian Observatory for Human Rights said at least seven fighters were killed in the fighting in Abu Zuhour, in addition to an unknown number of soldiers. The group, which relies on a network of activists on the ground, said the Syrian air force conducted an airstrike on Abu Zuhour village during the fighting to ease pressure on government troops inside the base.

Rebels control much of Idlib and Aleppo provinces, which border Turkey, although government troops still hold some areas including the provincial capital of Idlib province and parts of the city of Aleppo, Syria's largest urban center.

The Aleppo Media Center said rebels also seized 60 percent of the Mannagh helicopter base near the border with Turkey. Rebels from the Islamist al-Burraq Brigades announced that fighters from multiple factions in northern Aleppo have launched a large-scale offensive to seize full control of the facility.

Government troops regularly shell nearby areas from the Mannagh base, including a rocket attack overnight on the town of Tal Rifaat near the border with Turkey that killed at least four people, including two women and a child.

Syria's conflict started with largely peaceful anti-government protests in March 2011 but eventually turned into a civil war. More than 70,000 people have been killed, according to the United Nations.

The Obama administration said Thursday that intelligence indicates that government forces likely used chemical agents against rebels in two attacks.

Washington's declaration was its strongest on the topic so far, although the administration said it was still working to pin down definitive proof of the use of chemical weapons. It held back from saying Damascus had crossed what President Barack Obama has said would be a "red line" prompting tougher action in Syria.

Both sides of the civil war accuse each other of using the chemical weapons.

The deadliest such alleged attack was in the Khan al-Assal village in the Aleppo province in March. The Syrian government called for the United Nations to investigate alleged chemical weapons use by rebels in the attack that killed 31 people.

Syria, however, has not allowed a team of experts into the country because it wants the investigation limited to the single Khan al-Assal incident, while U.N. Secretary-General Ban Ki-moon has urged "immediate and unfettered access" for an expanded investigation.

The state-run al-Thawra newspaper on Sunday accused the U.N. secretary general of being a "tool" for the United States and accused him of "bowing to American and European pressures."

In neighoring Lebanon, Hezbollah's Al-Manar TV reported that Russia's Deputy Foreign Minister Mikhail Bogdanov met Saturday night with the pro-Syrian militant group's leader, Sheikh Hassan Nasrallah. No details emerged of the late night meeting.

The Shiite Muslim group has been drawn into the fighting in Syria and is known to be backing regime fighters in Shiite villages near the Lebanon border. The Syrian opposition accuses fighters from the group of taking part in the Syrian military crackdown inside the country.

At a Sunday morning at a news conference in Beirut, Bogdanov called for a diplomatic solution to Syria's civil war based on the Geneva Communique of June 2012. The communique is a broad but ambiguous proposal endorsed by Western powers and Russia to provide a basis for negotiations.

Earnings beating forecasts but jury's out on rest of season

NEW YORK (Reuters) - U.S. companies have easily beaten expectations for first-quarter earnings so far in the reporting season, but nearly half of the members of the S&P 500 are yet to announce results and they are unlikely to be as robust. With results in from 271 of the S&P 500 companies, year-over-year earnings growth is projected at 3.9 percent, compared with a forecast for 1.5 percent growth at the start of the earnings season, Thomson Reuters data shows. That figure includes those that have reported and analyst estimates for those who have not.

Abu Dhabi plans financial free zone, may resemble Dubai

ABU DHABI (Reuters) - The oil-rich emirate of Abu Dhabi is putting finishing touches to plans to establish a financial free zone that could resemble, and therefore compete with, the Dubai International Financial Centre, sources familiar with the matter said. A federal decree was passed by the United Arab Emirates' President Sheikh Khalifa bin Zayed al-Nahayan in February to create the area, known as the Abu Dhabi World Financial Market, on Al Maryah island, the sources told Reuters.

Italian court rejects Nomura seizure order: sources

SIENA, Italy (Reuters) - An Italian judge has rejected an order to seize around 1.8 billion euros ($2.3 billion) of assets from Nomura as part of a probe into suspected fraud involving troubled lender Monte dei Paschi di Siena , legal sources said on Saturday. Assets worth 140 million euros that were already seized from the Japanese bank have been released under the judge's ruling, which was made on Friday, the judicial source said.

Vodafone investors want bigger bid or full takeover by Verizon

LONDON (Reuters) - Six major Vodafone investors said $100 billion was not enough for the British company's stake in its U.S. joint venture with Verizon Communications , and urged the latter to come up with an offer of at least $120 billion. Their comments followed a Reuters report on Wednesday that Verizon had hired advisers to prepare a possible $100 billion bid to buy Vodafone's 45 percent stake in their Verizon Wireless joint venture, likely to be structured as a roughly 50:50 cash and stock bid.

Mark Goulston, M.D.: How to Make Your Marriage Last Longer Than ...

Have you ever noticed how an intimate relationship becomes different as soon as the couple (and usually the bride with her family) start planning the wedding? In many cases, the groom can look a little shell-shocked by the time he says, "I do." Given that this is a very common phenomenon, I reached out to Jerome and Tracey Carter, authors of How To Make Your Marriage Last Longer Than The Wedding and asked them about this:

Why is it that as soon as a couple says I do; at the first sign of adversity, they really don't?

• Unrealistic expectations going into the marriage. Based upon how you were raised or how much TV you watched, you may have a totally different view of how marriage should be than your spouse. Communicate and discuss your expectations of marriage before the wedding and definitely during the marriage.


• Lack of pre-marital coaching/counseling/ education. Marriage isn't anything to be entered into lightly. You must seek out wise counsel to be sure that you understand the many dynamics and the magnitude of a marriage relationship.

Why is it that we can say the vows during the wedding ceremony but we can't live the vows during the marriage journey?

• Lack of understanding of what marriage really is. Not having the courage or maturity to understand that marriage is a marathon and not a sprint will have you forget your vows on your wedding night.


• Poor models and examples of what marriage really is. If the only model you and I have of marriage are the poor examples in our family, where will we get an idea or picture of what a healthy, successful marriage looks like?

Why is it, a spouse can get along with everyone on the job, at the gym, at the school, at the church, in the community, in the office; but they can't get along with their spouse at home?

• Because it is easy to wear a mask around others who don't really know the real you. Most people wear a mask and put up a front to uphold their reputation every day. They never really display the real them because they don't know who they really are. It's a frightening marriage when one or both spouses don't know who they really are within and outside of the marriage.


• Because we make everybody else and every place a priority other than our spouse and our family. Our family must be our #1 priority. I've counseled countless men that have lost the very thing they said they were going to work to provide for; how sad is that!


• Because it takes work to maintain a successful marriage relationship. The wedding is fun the marriage is work (but it can be fun too)!

What can couples do so they won't experience marriage regret after the wedding?

• Date at least 1-2 years before getting married. You must spend time with your spouse so you can get to know them before marriage. I believe you must see all the seasons of a year while dating. There could be a change and difference from summer, fall, winter and spring but you will never know that if you rush into marriage. Be patient and see the four seasons while dating.


• Always be honest with each other during the courting process. Make sure the real you is being presented during the dating and courting process, so the data won't be skewed.


• Don't ignore the warning signs. The first time he/she shows you who they really are, believe them. What you see is what you get. They probably won't change and you probably won't change them. Don't get married if you see "deal breakers" during the dating and courting process.

What are the three most common surprises after the wedding?

• Lack of honesty. Always be honest about your feelings and who you really are; don't pretend to be something just to impress your spouse. That will get tired really fast!


• Not making the marriage a priority. Once you are married, your spouse and marriage must be your top priority in life.


• Competing with instead of complementing each other. You and your spouse are on the same team. You can accomplish so much by working together; however you can quickly destroy your marriage by working apart.

What are the four best tips for extending the Honeymoon so it is never over?

• Date night once a week. You must make your marriage a priority and date at least once a week; even if it is just investing in a 2 dollar ice-cream or coffee and walking in the park!


• Quarterly weekend get a ways without the kids. At least four times a year, you and your spouse should take mini trips to get away from kids, family and friends; so the two of you can reflect on your marriage and spend time with each other.


• Couples retreats at least once a year. Attend a couples conference or retreat with other like minded couples so you can learn how to build, invest in and strengthen your marriage!


• Laughter and plenty of it daily. Please take your marriage seriously; but you don't have to take yourself that seriously. Find time to laugh and find the humor in the mistakes and difference that you and your spouse will encounter over the course of your marriage journey.

Itihasa made itihasya...: Thoughts on education and learning...

skip to main | skip to sidebar

Reimagining education, learning and society...some ramblings

Schools, learning, teaching, universal access, textbooks and more ...Matters educational are tenuously holding centre stage in contemporary India where otherwise facetious debates on corruption, gender violence, caste and communal fracases, economic stimulus and likes, form the cynosure of public attention,?? determined and defined mostly by hyperventilating TV news anchors and some by scholars and experts? in ed and op ed pages of leading dailies. But in their discourses, issues connected to education emerge often in terms of numbers: poor enrollment, high drop out rates or when lamenting the qualitative aspects; poor infrastructure, pitiable computing, reading and writing abilities, ( resulting mostly from) woeful teaching standards.

However such concerns appear very normalizing wherein other knowledge paradigms and possibilities of learning and teaching is barely taken cognizance of. So even when the tardy enforcement of RTE, viewed to be a progressive legislation to universalize education in India,? is seen with dismay by many, it is largely done so, perhaps unconsciously, as failure to enforce and 'democratize' a standardized vision of learning which also embeds certain dominantly accepted epistemes and knowledge systems.

Issues I have with studies and reports like ASER and PROBE and the alarming inferences that many draw is the fact that learning and literacy are seen as a very formal attribute. One certainly cannot but concede that literacy is what makes abstraction possible and enhance the quality of perception, observation and is transformative. No one can really find fault with a processes that seeks to activate the abstraction capabilities, and scholars such as David Olson, Jack Goody and Walter Ong have argued? that it is literacy that sharpens if not shapes culture as well as cognition, and which separates 'primitive' from 'civilized' societies and that 'mastery of a written language affects not only the content of thought but also the process of thinking - how we classify, reason, remember.' (references here)? But as Sylvia Scribner and Michael Cole contend the impact of literacy is complex and localized and cannot be described in terms of 'generalized changes in cognitive abilities'.??In this even Paulo Freire, the icon for critical schooling and political empowerment of the oppressed masses who envisaged a 'praxological' 'dialogic' form of pedagogy attempting to 'liberate' one from 'magical' consciousness to critical ability, stressed the act of reading and the importance of writing. However orality does continue in Freire's thought even when he privileges writing, reading as facilitating abstraction, in his emphasis of dialogue.? (reference here)? Dialogue is basically oral and in Freire's stress on reflexivity and praxis, he seeks to develop a sort of interior dialogue which links theory and action to social reality. When Freire suggests reading of the word has to be preceded by reading of the world, such an understanding is derived orally, '...even the spoken word flows from the reading of the world.' But since Freire's approach is democratic and egalitarian transformation through conscenciatization his goal, he adds that, '...we can say that reading the word is not just preceded by reading of the world but by certain form of writing it or rewriting it, that is, of transforming it by means of conscious practical work. For me this dynamic movement is central to the literacy process.' (reference here)
Consequently some argue that Freire and his followers failed to realize that literacy itself is often a colonizing process that reinforces a modern form of individualism. (reference here)? Further let us consider the study of Thomas Farrell who had asserted that many Black students-particularly those from inner-city? backgrounds- in the US have been socialized? in the purely oral cognitive patterns of Black English, which is essentially a spoken rather than written language. Consequently he observed that they lack control of the full? panoply of conjugations and coordinating and subordinating syntax that distinguish standard written English which form a necessary matrix? for abstract and analytic thought. Donald Lazere a scholar of literacy and media who tried using literature that black students could relate to like autobiography of Malcolm X or James Baldwin's 'Notes of a Native Son' in his advanced literature classes expecting that working-class Black students might better be able to relate to the subject matter was thwarted by their difficulties with the syntactic and intellectual complexities. In this these students leaned on readers (guides) in? handling new vocabulary and allusions and clearing exams. Further another scholar Lisa Delpit, also concludes from her experience teaching? Black inner-city children that? they dislike the current neglect of standard form and mechanics and want instruction in the? formal skills they need to progress in schooling. (Reference here)? In India many Dalits too maintain a similar position who want to be 'equal participant' and seek 'empowerment' because the past for them means nothing - no worthwhile skills other than menial and extremely derogatory work and therefore memory of past is one of exploitation and oppression. In the present, a normative education (despite all the warts and problems) is certainly more liberating.? But needless to say such formal schooling does entrap us into normative and regulative socio-politico regime which far from being liberating becomes another oppressive institution of modernity.

Therefore does it mean modes of cognition, perception and learning which are tied more to the concrete, specific and tangible have outlived their utility and relevance? I also ask this - Did not orality also nurture superior craft skills which more than the literate sections of the populace sustained us for thousands of years - fed us, clothed us and helped us survive wars, epidemics and hunger? help us make beautiful monuments, art and also brought about understanding of human body, physical world and more?

Schools as operationalized in certain formal space and time, even when enabled by a sensitivity to evolve a curriculum which is cognizant of the childs' social and cultural experience, resulting in a child centred, socially and culturally appropriate pedagogy and an inter-disciplinary and integrated curriculum, has its inherent limitations. These are particularly exacerbated in our age and time of super specialization and performance - where formal exhibition of knowledge in the abstract thru tests and examination - has become sine qua non to prove one's accomplishment and one's employment worth.

Indeed the point is our sense of shock, despair and lament at such poor 'showing', would perhaps not be so profound if it were that these school drop outs could still sustain themselves in work that ensures good living wages facilitating a life of dignity and self respect. The issue many perhaps worry about here is the fact that India does not have a well equipped labour force to work either in factories or in cubicles. In such a scheme of things, where manufacturing (mass produced in conveyor belt form) and services ( particularly IT enabled) which is predicted to contribute the most to GDP, and a high GDP and growth rate would then give us something to brag about, is being jeopardized.

In dealing with this anxiety and satisfying globally benchmarked and defined norms of literacy, education and learning, variables like pedagogy, teacher training, textbooks etc are reframed to make it relevant to the most deprived children and consciously tailored to seek their empowerment. But yet even accounting for few who do and will benefit from these well meaning interventions derived from critical theories of Habermas and Friere, it will in the end precisely do that i.e. enhance only a few.

Nevertheless let us look it matters this way...what if we have a an economy where agriculture and crafts can continue to provide for one's existence (beyond hand to mouth as it were) something which can be more environmentally sustainable, less competitive and ensures that we do not as a society sink to ribald consumerism?

An example will perhaps help to make my point with greater clarity. I know this carpenter whose services we have been availing for more than 10 years. He is a carpenter par excellence but (and I use but with a slant) a school drop out. The way he determines the quality of wood, is able to cut the wood with finesse, shape it into beautiful chairs, tables and cots is seen to be believed. It is evident that his craft displays an acute understanding of mathematical and geometric proportions, weight, mass along with a deep sense of aesthetics. Now his whole skill can be abstracted and presented in terms of non-figurative and theoretical? knowledge through formulas, axioms, theorems, hypothesis etc to students in classrooms. And if my carpenter friend was to be seated in the same classroom it is possible that he is at a complete loss (the key word is possible here...) but we cannot blame him (and the teacher as well or for that matter the curriculum) if he is at pains to understand the concept and even flunks all evaluative processes. On the other hand one may also claim that given the contextual and embedded learning in operation here, my carpenter can make the leap to abstract thinking and grasping. But my contention here is the tenuous nature of such abstraction .


One's credentials as someone who is learned need not be limited by abstracted abilities and skills exhibited through formalized learning spaces (schools/colleges) and its normative practices.? What is more important in my view is their politicization and equipping them with citizenship attributes. A Frierian vision of politicization and empowerment is not precluded because of? poor articulation in writing and deficient reading skills. In other words citizenship and criticality does not and need not hinge on formal literacy abilities. What if my carpenter friend also showed perceptible political consciousness, recognizing aspects of his work as being so fundamental to the material culture we have, takes pride in it but seeks adequate compensation that affords him a better quality of life? What if he says,' No! I dont have any regrets in being a carpenter and I wont insist that my children need the kind of education that will ensure them 'better' jobs as long as this job or any other which they are comfortable doing, emerges from skills and competencies they have proclivities for, arising organically from their socialization and exposure which 'formal schooling' enhances and nurtures it, rather than trying to impose something new on them. It should ensure a life of dignity and decency. Their work should not confine them to living in hovels with poor sanitation, power and deny them some creature comforts. (beyond mobile phones and TV!!!) So if carpentry, farming, garage work, masonary, etc, professions more fundamental to our existence than that of a IT code jockey, bank manager and even a doctor or an engineer, and can ensure us good quality of life, in what ways are we less important or our work less dignified or are we of any inferior intelligence?'

Of course, truth be told my carpenter nurses a deep sense of inferiority and neither does he exhibit such critical and politically edifying thoughts. He certainly does not want his sons (and even daughters thankfully) to have anything to do with carpentry and dreams of his kids becoming good techies and engineers working in false roofed, glass fronted A/C buildings.? But in my view my carpenter is a victim of double whammy - stigmatized as failure by education and lacking political and citizenship consciousness. This despite the brilliance he brings forth to his work which adds so much value to so many people. Tragic indeed. But if we lived in a world where one's intelligence, survival did not depend on such economic externalities and warped by skewed social values, would my carpenter be facing this crisis? This is precisely what Gandhi feared and sought a more organic and integrated school model not divorced from work as he argued in his Nai Talim. This dovetailed well into the non-industrial and non-urban vision he had for India based on his visceral understanding of modernity and its pathologies engendered by commerce, consumption and competition.

At certain levels such a perspective may appear elitist and Brahmanical. I have already dwelled on this aspect here and would not repeat myself.



II

As a teachers I think we need to understand the larger context elucidated above and work towards using pedagogies that can still overcome these structural constraints. Now this is not easy and I dont think I myself succeeded in much measure in this direction. I was teaching in a school catering to middle classes and had to do the needful to put them on an aspirational path. Also the training programmes offered by these schools with its obsession on performance never helped me to understand issues in the manner I'm increasingly begin to look at. As teachers we were given to, rather than subject to accountability and therefore lots of training on appropriate teaching methods, child centred teaching, multiple intelligences and blah blah we were inflicted upon.? Regarding these I recently came across this blog? by Subir Shukla. As Subir says over the last two decades, there has been an explosion of 'pedagogies'...(and government, NGOs etc) have all come up with what they consider 'sure fire' methods of teaching...(to make) classroom processes...interesting, 'joyful' activities will be conducted, teaching learning material and 'learning ladders' will be used, and so on.

What Subir says next is more significant, 'At the heart of it all though, is the basic tenet that if the teacher really cares for his children, he will find a way. All these pedagogies begin to have meaning only if the teacher is interested in children and finds delight in helping them learn. Now most of our training programmes, materials and pedagogical models might claim to be make teaching more effective, but they don't necessarily generate that emotional commitment to children and their learning that is a prerequisite to successful classroom processes.'?








Modernity as we have it then predicates on such an education system and institutionalized nature of work. To conclude

Google Glass' vision of the future runs on a 2011 smartphone chip

Google Glass may represent the future of wearables, but its components are a vestige of the past -- 2011, to be exact. That's according to developer Jay Lee who dug up some interesting Glass tidbits using Android Debug Bridge. Taking to his Google+ page, Lee verified that Google's smart eyewear currently runs on Android 4.0.4 Ice Cream Sandwich - a fact CEO Larry Page has apparently fessed up to -- incorporates an OMAP 4430 processor running at an unspecified frequency and is paired with about 682MB RAM (out of a likely 1GB), though it's not clear if this is a dual-core setup. For non-mobile industry historians, this particular Texas Instruments OMAP chipset hasn't been used since the Droid Bionic and Atrix 2 in 2011, making it relatively ancient by industry standards. So, what other surprises lurk beneath the Glass? We'll leave those mysteries to our EIC Tim Stevens to suss out in his Glass diaries.

93% No

All Critics (98) | Top Critics (31) | Fresh (91) | Rotten (7)

"No" is a picture that perches precariously on the cusp of a paradox.

A cunning and richly enjoyable combination of high-stakes drama and media satire from Chilean director Pablo Larrain.

A mesmerizing, realistic and often hilarious look at the politics of power and the power of ideas ...

A political drama, a personal drama, a sharp-eyed study of how the media manipulate us from all sides, No reels and ricochets with emotional force.

It's a funny look at the way the media warp public opinion, and a curiously hopeful one.

On every level, "No" leaves one with bittersweet feelings about democracy, love and the cost of compromise.

"NO" is an inspirational political drama in which the people are roused by the visual to overcome the vicious.

... features a fine performance by Gael Garc?a Bernal as young ad exec Ren? Saavedra, who didn't, at first, quite realise what he was in for when he decided to assist in the bringing down of military dictator Augusto Pinochet.

No is a great historical document as to how one very important revolution started with a commercial.

The understated performance by Bernal was inspiring, as was the pic.

It's not easy material but it's truly fascinating, and expertly done.

An extremely perceptive and intriguing examination of the effect that media hype and spin have on the political process.

...a bitter and knowing meditation on media manipulation and political subversion.

Larrain deftly mixes social satire and historical drama.

All historical and little drama.

Larrain does a fine job of making No look and sound authentic to its time period, although the VHS-quality photography, all washed-out with colors bleeding together as camcorders did in the '80s, is an occasional irritant.

Silliness is on the side of the angels in a brilliant and highly entertaining film that's part political thriller, part media satire.

It's clear that the language of advertising has become universal, and that political commodities can be sold like soap. But toppling a dictatorship? Now there's a story.

A reflection of a moment in time, made in the image of that moment.

Bernal deftly explores the layers of the character's complexity, including his political apathy.

"No" is filmmaking of the first order.

Old technology plus the packaging of a revolution add up to a Yes

Freshens up a decades-old story with vibrant humor and a good sense of storytelling.

No continually impresses for its slyness and savvy -- rarely has such an eyesore been so worth watching.

Nintendo's digital game sales hit an all-time high

Nintendo's hardware sales may be in a bit of a stupor, but its downloadable games are a different story. During today's financial results briefing, the company's president, Satoru Iwata, announced that digital sales for the 2013 fiscal year, which ended in March, cruised past ¥16 billion (around $160.9 million), more than doubling transactions from the last two years. Nintendo's frontman went on to credit the demand for downloadable game add-ons and the convenience of digital titles as contributing factors in the company's surge. Iwata also pointed out that most 3DS owners are using their systems online. This includes 87 percent of the handheld's owners in Japan and 83 percent in the US. While these numbers are impressive, the system's internet use statistics start to dwindle in Europe, where its user connectivity rate is only 57 percent. The Wii U's user base is almost as connected, with 80 percent of the platform's owners taking the system online The company's e-commerce may be thriving, but we wouldn't bet on seeing Nintendo announce a download-only console during its E3 keynote presentation.

VIDEO: The Future Of Wearable Technology

Google Glass ? the glasses with a computer, Internet and camera built in ? is only the latest version of wearable technology. The wristwatch was one of the first.

Off Book, a Web video series from PBS, explorers the future of wearable technology ? from devices that help you figure out why you can't sleep to "smart" fabrics.

"For example, think about a garment you don't have to wash," says Sabine Seymour of Parsons, the New School for Design. "They can change their shape, their color ... fabrics that have a metallic coating, or yarns that are conductive. We want to make the actual fiber smart, so that through nanotechnology we can create a textile that can sense."

Movement of pyrrole molecules defy 'classical' physics

Apr. 26, 2013 ? New research shows that movement of the ring-like molecule pyrrole over a metal surface runs counter to the centuries-old laws of 'classical' physics that govern our everyday world.

Using uniquely sensitive experimental techniques, scientists have found that laws of quantum physics -- believed primarily to influence at only sub-atomic levels -- can actually impact on a molecular level.

Researchers at Cambridge's Chemistry Department and Cavendish Laboratory say they have evidence that, in the case of pyrrole, quantum laws affecting the internal motions of the molecule change the "very nature of the energy landscape" -- making this 'quantum motion' essential to understanding the distribution of the whole molecule.

The study, a collaboration between scientists from Cambridge and Rutgers universities, appeared in the German chemistry journal Angewandte Chemie earlier this month.

A pyrrole molecule's centre consists of a "flat pentagram" of five atoms, four carbon and one nitrogen. Each of these atoms has an additional hydrogen atom attached, sticking out like spokes.

Following experiments performed by Barbara Lechner at the Cavendish Laboratory to determine the energy required for movement of pyrrole across a copper surface, the team discovered a discrepancy that led them down a 'quantum' road to an unusual discovery.

In previous work on simpler molecules, the scientists were able to accurately calculate the 'activation barrier' -- the energy required to loosen a molecule's bond to a surface, allowing movement -- using 'density functional theory', a method that treats the electrons which bind the atoms according to quantum mechanics but, crucially, deals with atomic nuclei using a 'classical' physics approach.

Surprisingly, with pyrrole the predicted 'activation barriers' were way out, with calculations "less than a third of the measured value." After much head scratching, puzzled scientists turned to a purely quantum phenomenon called 'zero-point energy'.

In classical physics, an object losing energy can continue to do so until it can be thought of as sitting perfectly still. In the quantum world, this is never the case: everything always retains some form of residual -- even undetectable -- energy, known as 'zero-point energy'.

While 'zero-point energy' is well known to be associated with motion of the atoms contained in molecules, it was previously believed that such tiny amounts of energy simply don't affect the molecule as a whole to any measurable extent, unless the molecule broke apart.

But now, the researchers have discovered that the "quantum nature" of the molecule's internal motion actually does affect the molecule as a whole as it moves across the surface, defying the 'classical' laws that it's simply too big to feel quantum effects.

'Zero-point energy' moving within a pyrrole molecule is unexpectedly sensitive to the exact site occupied by the molecule on the surface. In moving from one site to another, the 'activation energy' must include a sizeable contribution due to the change in the quantum 'zero-point energy'.

Scientists believe the effect is particularly noticeable in the case of pyrrole because the 'activation energy' needed for diffusion is particularly small, but that many other similar molecules ought to show the same kind of behavior.

"Understanding the nature of molecular diffusion on metal surfaces is of great current interest, due to efforts to manufacture two-dimensional networks of ring-like molecules for use in optical, electronic or spintronic devices," said Dr Stephen Jenkins, who heads up the Surface Science Group in Cambridge's Department of Chemistry.

"The balance between the activation energy and the energy barrier that sticks the molecules to the surface is critical in determining which networks are able to form under different conditions."
