Tata Consultancy Services, part of the Tata Group, expects to hire 65,000 people this year, up from 38,000 last year and 700 in 1986. <br /><br />Trying to bridge the widening chasm between job requirements and the skills of graduates, Tata has extended its internal training program. It puts fresh graduates through 72 days of training, double the duration in 1986, says Tata chief executive N. Chandrasekaran. Tata has a special campus in south India where it trains 9,000 recruits at a time, and has plans to bump that up to 10,000.<br /><br />Wipro runs an even longer, 90-day training program to address what Mr. Govil, the human-resources executive, calls the "inherent inadequacies" in Indian engineering education. The company can train 5,000 employees at once.<br /><br /><b>Both companies sent teams of employees to India's approximately 3,000 engineering colleges to assess the quality of each before they decided where to focus their campus recruiting efforts.

More than half of India's population is under the age of 25, and one million people a month are expected to seek to join the labor force here over the next decade, the Indian government estimates. The fear is that if these young people aren't trained well enough to participate in the country's glittering new economy, they pose a potential threat to India's stability.<br /><br />...<br /><br />"I was not prepared at all to get a job," says Pradeep Singh, 23, who graduated last year from RKDF College of Engineering, one of the city of Bhopal's oldest engineering schools. He has been on five job interviews—none of which led to work. To make himself more attractive to potential employers, he has enrolled in a five-month-long computer programming course run by NIIT. <br /><br /><b>Mr. Singh and several other engineering graduates said they learned quickly that they needn't bother to go to some classes. "The faculty take it very casually, and the students take it very casually, like they've all agreed not to be bothered too much," Mr. Singh says. He says he routinely missed a couple of days of classes a week, and it took just three or four days of cramming from the textbook at the end of the semester to pass the exams.</b><br /><br /><b>Others said cheating, often in collaboration with test graders, is rampant. Deepak Sharma, 26, failed several exams when he was enrolled at a top engineering college outside of Delhi, until he finally figured out the trick: Writing his mobile number on the exam paper. </b><br /><br />That's what he did for a theory-of-computation exam, and shortly after, he says the examiner called him and offered to pass him and his friends if they paid 10,000 rupees each, about $250. He and four friends pulled together the money, and they all passed the test. <br /><br />"I feel almost 99% certain that if I didn't pay the money, I would have failed the exam again," says Mr. Sharma.<br /><br />BC Nakra, Pro Vice Chancellor of ITM University, where Mr. Sharma studied, said in an interview that there is no cheating at his school, and that if anyone were spotted cheating in this way, he would be "behind bars." He said he had read about a case or two in the newspaper, and in the "rarest of the rare cases, it might happen somewhere, and if you blow [it] out of all proportions, it effects the entire community." The examiner couldn't be located for comment.<br /><br />Cheating aside, the Indian education system needs to change its entire orientation to focus on learning, says Saurabh Govil, senior vice president in human resources at Wipro Technologies. Wipro, India's third largest software exporter by sales, says it has struggled to find skilled workers. The problem, says Mr. Govil, is immense: "How are you able to change the mind-set that knowledge is more than a stamp?"<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3734925856292601239.post-27711030252588778252014-04-10T13:14:55.843-04:002014-04-10T13:14:55.843-04:00Here's an overview of some of the "talent...Here's an overview of some of the "talent" the Indian education system is producing:<br /><br />http://online.wsj.com/news/articles/SB10001424052748703515504576142092863219826<br /><br />BANGALORE, India—Call-center company 24/7 Customer Pvt. Ltd. is desperate to find new recruits who can answer questions by phone and email. <b>It wants to hire 3,000 people this year. Yet in this country of 1.2 billion people, that is beginning to look like an impossible goal. </b><br /><br /><b>So few of the high school and college graduates who come through the door can communicate effectively in English, and so many lack a grasp of educational basics such as reading comprehension, that the company can hire just three out of every 100 applicants.</b><br /><br /><b>India projects an image of a nation churning out hundreds of thousands of students every year who are well educated, a looming threat to the better-paid middle-class workers of the West. </b>Their abilities in math have been cited by President Barack Obama as a reason why the U.S. is facing competitive challenges.<br /><br />Yet 24/7 Customer's experience tells a very different story. <b>Its increasing difficulty finding competent employees in India has forced the company to expand its search to the Philippines and Nicaragua. Most of its 8,000 employees are now based outside of India.</b><br /><br />In the nation that made offshoring a household word, 24/7 finds itself so short of talent that it is having to offshore.<br /><br /><b>With India's population size, it should be so much easier to find employees," says S. Nagarajan, founder of the company.</b> "Instead, we're scouring every nook and cranny."<br /><br />India's economic expansion was supposed to create opportunities for millions to rise out of poverty, get an education and land good jobs. But as India liberalized its economy starting in 1991 after decades of socialism, it failed to reform its heavily regulated education system.<br /><br />Business executives say schools are hampered by overbearing bureaucracy and a focus on rote learning rather than critical thinking and comprehension. Government keeps tuition low, which makes schools accessible to more students, but also keeps teacher salaries and budgets low. What's more, say educators and business leaders, the curriculum in most places is outdated and disconnected from the real world.<br /><br />"If you pay peanuts, you get monkeys," says Vijay Thadani, chief executive of New Delhi-based NIIT Ltd. India, a recruitment firm that also runs job-training programs for college graduates lacking the skills to land good jobs.<br /><br />Muddying the picture is that on the surface, India appears to have met the demand for more educated workers with a quantum leap in graduates. Engineering colleges in India now have seats for 1.5 million students, nearly four times the 390,000 available in 2000, according to the National Association of Software and Services Companies, a trade group.<br /><br /><b>But 75% of technical graduates and more than 85% of general graduates are unemployable by India's high-growth global industries, including information technology and call centers, according to results from assessment tests administered by the group. </b><br /><br />Another survey, conducted annually by Pratham, a nongovernmental organization that aims to improve education for the poor, looked at grade-school performance at 13,000 schools in rural areas in India, where more than 70% of the population resides. <b>It found that about half fifth graders can't read at a second-grade level in India. </b><br /><br />At stake is India's ability to sustain growth—its economy is projected to expand 9% this year—while maintaining its advantages as a low-cost place to do business. <br /><br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3734925856292601239.post-16564147400272997722014-04-10T13:13:07.122-04:002014-04-10T13:13:07.122-04:00I find it very very unlikely that India's educ...I find it very very unlikely that India's education system or classrooms outclasses America in any respect.

Beavers, for example, have more impressive artifacts than cetaceans, but we are told that cetaceans are more intelligent.

I was quick to state that the exact opposite might be the case under some circumstances since, as has been shown in computer architecture, the region of control (the amount of space that signals must traverse in a clock cycle) is minimized in order to maximize computation flexibility (take branches, etc.). I also added that brain size might have some unknown function for organisms that must navigate the oceans -- such as cetacea and, of course, Hawaiians. That shut her up.

Professor Philip A. Vernon of the University of Western Ontario and his colleagues have summarized studies of the correlation between intelligence and head size, and the correlation between intelligence and the size of the brain itself. Every one of 54 studies that measured head size showed a positive relationship, with an overall correlation of 0.18. Research using CT (computerized axial tomography) and MRI (magnetic resonance imaging) gives a more accurate measure of brain size, and the 11 studies that used these methods found an overall correlation with intelligence of 0.40. Prof. Vernon and his colleagues conclude that brain size must be a determinant of intelligence because larger brains have more neurons and this gives them greater processing capacity."Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3734925856292601239.post-57934005581829371952014-04-08T10:20:19.778-04:002014-04-08T10:20:19.778-04:00Wiki explains the source of Microcephalin in non-s...Wiki explains the source of Microcephalin in non-sub-Saharan populations as a result of a possible introgression of Neanderthal genes in Moderns.<br />http://en.wikipedia.org/wiki/Microcephalin<br /><br />But so far the allele has not been found in reconstructed Neanderthal genomes. <br />However, I would expect a significant genetic divergence (drift) in their isolated populations since they had much more time to drift away than Moderns.

But on switching to farming, with a lower quality and quantity of protein along with frequent famines, such mitochondia may have been maladaptive.Seannoreply@blogger.comtag:blogger.com,1999:blog-3734925856292601239.post-36952521504905215822014-04-07T22:23:20.807-04:002014-04-07T22:23:20.807-04:00"Never mind that there are good reasons to be..."Never mind that there are good reasons to believe that civilization is or can be quite dysgenic."<br /><br />Aha!

Both polar bears and eskimos live in the cold, but they obviously do so in quite dramatically different ways. <br /><br />Humans expanded into cold climates relatively quickly and appear to have adapted primarily through mental, behavioral, and cultural means rather than through more physiological means such as thick blubber and fur coats which would have taken much longer to evolve.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3734925856292601239.post-34992919832188787612014-04-07T18:19:06.734-04:002014-04-07T18:19:06.734-04:00Natural selection just selected for people lasting...Natural selection just selected for people lasting more time in cold.
