KAPALUA, Hawaii – Lucas Glover became the first player to make a hole-in-one in the eight years the Mercedes Championships has been played at Kapalua, using a 5-iron to ace the 203-yard eighth hole. Glover bent over is disbelief, then exchanged a high-five with playing partner Mark Calcavecchia. Along with getting into contention at the season-opening event, Glover won a Mercedes-Benz CLS55 AMG, a value of $87,375. Glover got into the field by holing a 35-foot bunker shot on the final hole of the Funai Classic at Disney in October. In the two months since the season ended, he graduated from Clemson and got married. He opened the new season by making bogey on his first four holes, but the ace got him within one shot of the lead.

His wobbly legs testify to the atrophy his muscles suffered in zero-G. Overcome by the smells of his native planet, and feeling queasy, he expects recovery to take some time. “It is going to be quite tricky for me to adapt,” he said in a news conference before landing. “It’s probably going to take me two or three days before I feel well. It will take me several months before my body fully recovers in terms of bone density.” Just half a year in space did this to him. Getting to sleep was hard and not particularly restful, Simon Archer says in The Conversation.Muscles wither, bones become lighter just as they do during the process of ageing and the cardiovascular system and vision are affected – all from the human body’s lack of adaptation to microgravity. No wonder: we have evolved over millions of years on Earth with its comforting gravitational pull.Astronauts are exposed to excessive radiation in space. How much? Martin Archer, a space plasma physicist, decided to find out. On The Conversation, he calculated that Peake faced the equivalent of a fatal X-ray dose up there (300 joules), but since it was spread out over months and partly protected by shielding in the international space station (ISS), he didn’t die. On the surface of the earth, we only get 0.07 joules in six months, less than four thousandths Archer’s calculation – and that’s at an altitude partly protected by the earth’s magnetic field. The implications are clear:Of course long-term exposure is very different from a short intense burst. Only astronauts who spent the entirety of those six months on a spacewalk would in fact get this lethal dose – the ISS itself helps shield them. In practice, this shielding helps limit their overall exposure to about a year’s worth of radiation that we get on Earth per day, meaning it is still some 365 times higher. Nevertheless, it’s a staggering comparison and really highlights the challenges to manned spaceflight that we’re currently facing. In interplanetary space, the radiation is even more dangerous. Here’s a concern that sci-fi screenwriters routinely ignore:But for missions further away from the Earth’s protective magnetic field, cosmic rays would be more of a problem. On its journey to Mars, the Curiosity rover provided crucial data on this and it was higher than expected. A round-trip manned mission to Mars would expose the astronauts to up to four times the advised career limits for astronauts of radiation due to galactic cosmic rays.OK, so astrobiologists will admit that life needs a planetary surface and possibly a magnetic field. What else? Science Daily adds a second rinse to the the widely-accepted requirement for water. If life is to have the complex molecules we know from living cells, water is needed to get them to fold properly. Proteins fold because the push-and-pull jostling of water molecules helps them find their native configurations quickly – assuming, of course, that the amino acids are properly sequenced. Dingping Zhong explains what his team at Ohio State found:“Here, we’ve shown that the final shape of a protein depends on two things: water and the amino acids themselves. We can now say that, on ultrafast time scales, the protein surface fluctuations are controlled by water fluctuations. Water molecules work together like a big network to drive the movement of proteins.“We’re down to rocky planets with magnetic fields and water. What else? Better have a quiet star. Joshua Sokol at New Scientist showed an artist conception of a star blasting a young planet with the kind of radiation sun-grazing comets get. An exoplanet named KIC 12557548b in Cygnus orbits so close to its star, he says, starspots with strong magnetic fields focus death rays at it. His description of the punishment the planet gets is not pretty.At the planet’s surface, radiation from the nearby star is hot enough to vaporise layers of exposed rock, after which a wind of charged particles – also from the star – blows that vapour into space.Star spots may increase the devastation. These dark patches, where the star’s magnetic field is concentrated, may act as death rays, blasting out more material when the planet passes in front of them. This could happen either because these patches emit high-energy radiation that can better chip into the rock, or because the swirling magnetic fields around them help yank the vapour into orbit.The star is peeling away the poor planet like the layers of an onion. It’s enough to make one cry.Venus, our planetary “twin”, is not a pretty place, either, as we found at the dawn of the space age. Here’s another factor that affects habitability: electric fields. In a video clip on Space.com, Goddard space scientist Glyn Collinson tells about his “amazing and shocking” discovery that Venus has “monster electric fields” strong enough to strip oxygen atoms from the planet. Even if Venus had started with water like Earth, therefore, it would have lost it all due to this process. His work was published in Geophysical Research Letters. In its review, Science Daily says that scientists don’t know why the electric field at Venus is so strong, five times that on Earth:Co-author, Professor Andrew Coates of the UCL MSSL, who leads the electron spectrometer team, said, “We’ve been studying the electrons flowing away from Titan and Mars as well as from Venus, and the ions they drag away to space to be lost forever. We found that over 100 metric tons per year escapes from Venus by this mechanism — significant over billions of years. The new result here is that the electric field powering this escape is surprisingly strong at Venus compared to the other objects.Titan loses 7 metric tons per year, by comparison. This adds another concern when assessing habitability of a planet:Understanding the role played by planet’s electric winds will help astronomers improve estimates of the size and location of habitable zones around other stars. “Even a weak electric wind could still play a role in water and atmospheric loss at any planet,” said Alex Glocer of NASA Goddard, a co-author on the paper. “It could act like a conveyor belt, moving ions higher in the ionosphere where other effects from the solar wind could carry them away.“Keeping score, we need a rocky planet with water, a weak electric field, and a safe distance from solar magnetic storms. What else? How about not one – not two – but three Van Allen belts? Science Daily tells about how the puzzling “third Van Allen belt” is created by a “space tsunami” of sorts. Intense solar storms create this third belt, resulting in the “transport [of] the outer part of the belt radiation harmlessly into interplanetary space.” We earthlings might suffer fluctuations in the power grid and damage to satellites, but we don’t die.The most numerous stars in the universe are the red dwarfs. We already knew that they were unlikely hosts for habitable planets, but more bad news was just announced by Astrobiology Magazine. New calculations show that “the width of the habitable zone around M-dwarf stars is not as wide as previously thought” due to Coriolis force heating as a function of orbital radius. That’s in addition to the problem that planets orbiting M-dwarf stars are likely to be tidally locked, with one hemisphere scorched by its star and the back side freezing cold. Ravi Kumar Kopparapu at Goddard Space Flight Center is trying to refine the habitable zones of these stars, and he’s not done yet. “His proposal will update our understanding of how water vapor can absorb incoming radiation from the star,” the article ends. “This can influence the warmth of a planet and further reduce the width of the habitable zone.” Goldilocks would have to get very, very lucky with the red dwarfs.OK, we didn’t prove Earth is unique, but these articles sure give food for thought about how perfect our planet is in every way… almost like it was designed. If the majority of stars lack the requirements to host life, how many are left?Let’s add #13 and #14 to the list of habitability requirements: (Visited 51 times, 1 visits today)FacebookTwitterPinterestSave分享0

The rise in value has come from at most 10-15 companies—the likes of Apple, Google, and Facebook.And while hundreds if not thousands of startups get funded every year, only a dozen or so even stand a chance of joining that pantheon.So the question for Rabois, who has worked at PayPal, LinkedIn, Slide, and Square, and backed startups like Yelp, Airbnb, and Yammer: What’s the trick?It’s The Product—But It’s Not Just The ProductWhen Rabois was at PayPal, he ran strategy and legal affairs—including figuring out how to deal with eBay, Visa, and Mastercard, all of which, he says, were trying to kill the payments startup. His training as an antitrust lawyer helped in figuring out PayPal’s competitive strategy—but PayPal didn’t fight primarily in the courts. It fought by getting eBay’s own users on its side.The advice is generally applicable to startups looking to build a business on a bigger company’s platform, as PayPal did by offering credit-card payments on eBay’s auctions site.An audience member asked if startups should band together to contest a company’s capricious or unfair manipulation of a platform on which they’re building businesses. Rabois said he didn’t think that would work.Instead, you have to fight by perfecting your product.“You have to build a product that real users love—not just use, but love,” said Rabois. “And you’ve got to figure out a way to get it in enough of their hands so they truly can’t live without it. Because then when the platform wants to change things, you have real people that are animated. And if those people are animated, they can go to the media, they can go to their congressmen. That’s what you have to have to protect yourself. Anything you do tactically isn’t going to help you. It’s got to be scaled, and it’s got to be true love…. Focus on that.”The Public RouteRabois is also on the board of two public companies, Yelp and Xoom. Yelp has seen a nice runup in its stock recently, and shares of Xoom, an international money-transfer service, are up from their IPO price even after a 59% first-day pop.That goes against conventional wisdom in Silicon Valley these days—that companies should delay going public as long as possible, and avoid the public markets if possible. (Evernote CEO Phil Libin, for example, has talked about his reluctance to take his company public.)Rabois said there were “two schools of thought”—entrepreneurs who are “deferring” IPOs, and entrepreneurs “who welcome it.”“If you’re building an enduring company, one that will last, say, 50 years, it is almost certain that the way you’re going to do that is by becoming a publicly traded company,” Rabois told me. “If your ambition in life is to transform the world through your product technology, and to continue to do that every generation, year after year, year after year, through different management, through different CEOs, a public company is a very good format to do that.”Rabois also noted that going public gives companies a currency for acquisitions.“It also means something to the public,” he said. “It’s actually a safer place to do business. And I think consumers react that way. I think LinkedIn going public was incredibly successful as a marketing campaign for the company. More people became aware of it and filled out profiles.”Rabois said we should expect to see more IPOs in September and October of this year.That’s just some of the ground we covered in our 45-minute chat.

SRKThe badshah of Bollywood has always known how to make people dance to his tunes, but master blaster Sachin Tendulkar was surely a first for him too.Shah Rukh Khan had flown down from Berlin, where he was busy shooting for Don 2, to attend the second edition of the Sahara Sports Awards on October 30. At the event, he got the cricketer to match steps with him during a dance performance. When we contacted SRK to ask how he managed to make it to the show, he replied: “I made it because I really like sports. I wanted to see all the renowned sportspersons of our country under one roof.”

The 11-member Chinese technical team is performing free cataract surgeries at the Kingston Public Hospital (KPH) on Jamaicans in need. The members, who began working at KPH from April 2 and will end on 26, comprise five ophthalmologists, three nurses, two engineers and one technician. Health Minister, Dr. the Hon. Christopher Tufton, says the visiting Bright Journey Eye Care Mission is set to exceed its target of 500 cataract surgeries. Story Highlights Health Minister, Dr. the Hon. Christopher Tufton, says the visiting Bright Journey Eye Care Mission is set to exceed its target of 500 cataract surgeries.The 11-member Chinese technical team is performing free cataract surgeries at the Kingston Public Hospital (KPH) on Jamaicans in need.The members, who began working at KPH from April 2 and will end on 26, comprise five ophthalmologists, three nurses, two engineers and one technician.Speaking with JIS News during his visit to the hospital on North Street in Kingston on April 18, Dr. Tufton said 440 persons have benefited from the mission to date.“We would like to show our appreciation to the Chinese delegation that are here doing the surgeries. They came a few weeks ago with a commitment to do 500 surgeries and I understand they have done some 440. So, we are well on target to achieving the 500 mark and I am told we may exceed that, so it really demonstrates the importance of partnerships in public health. The mission has been successful and we would like to see more of it,” he noted.Dr. Tufton said he welcomes the collaboration with the Chinese Government to support this area of healthcare.“Eye care is a significant area in Jamaica. It is typically underserved. We are moving to sharpen the policy and improve the focus to ensure greater prevention and buildout capacity for curative measures,” he said. Dr. Tufton said the collaboration has had several other positive results in shared knowledge and information between local and international medical teams.Retiree, Jo-Anne Bromfield, who had her surgery on April 10, said the experience was a positive one. “It was good. Thanks be to the Lord. I can see properly now,” she toldJIS News.Miguel Bradley, who also received the surgery on his right eye, said he can already see positive results from the procedure.“Things are brighter. I can see clearly. Before I had foggy vision, now I can see crystal clear,” he said.To date, 1,000 persons have been screened and 600 selected for surgery. In addition to the surgeries, the mission has also donated medical equipment to KPH, and offer training to the nurses and doctors.This is Bright Journey’s second visit to Jamaica. In May 2015, more than 200 Jamaicans benefited from free cataract surgeries at the KPH, while the hospital was gifted medical equipment and supplies valued at US$400,000.
ADVERTISING SALES OR REGIONAL MANAGERSALES PERSON, ACCOUNT EXECUTIVE, OR MANAGER METHODOLOGYThe survey sample of 771 was selected by Red 7 Media and Readex Research and represented all FOLIO: subscribers classified as sales management at the time of sample selection. Data was collected via mail survey from February 25 to April 9, 2008. The survey was closed for tabulation with 315 responses (a 41 percent response rate). To ensure representation of the audience of interest, results have been filtered to include only the 249 respondents who completed the compensation information, work full time, and indicated their job functions are best described as advertising sales director; advertising sales or regional manager; advertising salesperson, account executive, or category manager. The margin of error for percentages based on all 249 respondents is 4.8 at the 95 percent confidence level. Advertising sales is a hot field to be in right now. According to FOLIO:’s Industry Job Trends report from March, it’s one of the most in-demand areas of magazine publishing—so much so that Discover Media’s CEO Henry Donahue said demand was outstripping supply, driving salaries up. Executives from Aspire Media, National Geographic and CurtCo all noted plans to staff up on sales people to help drive revenue during economic downturn.But the sales directors, managers and reps who responded to FOLIO:’s Advertising Sales Salary Survey this year present a mixed report from the field—especially when it comes to the impact of e-media. “Online sales will offer additional earning potential,” one respondent said in a verbatim response. “Can’t make as much selling Web offerings as print pages, but they are just as time consuming,” said another.Still, the survey shows ad salaries, in many areas, are healthy and growing, particularly for ad sales or regional managers at consumer magazines who saw an increase of almost 27 percent in base salary last year over the year before.SALARY BY CATEGORY:ADVERTISING SALES DIRECTOR
