NBA fines Spurs $250,000 for sending starters home

Gregg Popovich sent his best players home, deciding they reached the end of the road before the trip was over.

For that, and for keeping it a secret, the San Antonio Spurs were fined $250,000 by the NBA on Friday.

Commissioner David Stern said the Spurs "did a disservice to the league and our fans" when they didn't bring Tim Duncan, Tony Parker, Manu Ginobili or Danny Green to Miami for the final game of the six-game trip.

"The result here is dictated by the totality of the facts in this case," Stern said in a statement. "The Spurs decided to make four of their top players unavailable for an early-season game that was the team's only regular-season visit to Miami. The team also did this without informing the Heat, the media, or the league office in a timely way. Under these circumstances, I have concluded that the Spurs did a disservice to the league and our fans."

Teams are required to report as soon as they know a player will not travel because of injury.

The league's statement said the Spurs were in violation of league policy reviewed with the board of governors in April 2010 against resting players in a manner "contrary to the best interests of the NBA."

The Spurs didn't comment on the penalty.

The issue of resting healthy players has been debated before, though usually at the end of the season, not a month into it. And the Spurs have been right at the center of it, Popovich using the rest strategy for an aging team that could use more time off than the NBA schedule often allows.

They even made a joke out of it last season, the box score listing "OLD" next to the 36-year-old Duncan's name as the reason he didn't play.

Stern wasn't laughing Thursday.

He has a nearly $5 billion a year industry to protect and can't like it when teams aren't willing to put their best product on display in a marquee game televised by national TV partner TNT. Fans and viewers were excited about seeing the Spurs try to complete an unbeaten road trip against LeBron James, Dwyane Wade, Chris Bosh and the NBA champions, so there was an understandable letdown when they learned of the absences.

But there's never a guarantee that any players are going to play, and Stern himself has previously made it clear he wasn't going to impose rules to change that.

The Cleveland Cavaliers rested a healthy James for four straight games at the end of the 2009-10 regular season. Owners discussed the issue later that week at a meeting in New York, and Stern reported that there was "no conclusion reached, other than a number of teams thought it should be at the sole discretion of the team, the coach, the general manager, and I think it's fair to say I agree with that, unless that discretion is abused."

In the NFL, the Indianapolis Colts rested a healthy Peyton Manning even with an undefeated record late in the 2009 season, and the league eventually started trying to schedule as many division matchups as possible for the final two weeks of the season in an effort to make late-season games matter.

Popovich doesn't wait until the end of the season to start resting players.

He was both praised and ripped for the way he navigated the lockout schedule last season, twice surrendering 11-game winning streaks by playing without his Big Three. Even those who didn't like it conceded that a coach who had won four championships with what's long been considered the NBA's model organization probably knew what he was doing, and more defense came Thursday night.

"Popovich has done this before and he knows what's best for his team," former NBA star Shaquille O'Neal said on TNT. "It's his job to manage his players and do whatever he'd like. He's thinking about the big picture."

Another former player turned TNT analyst, Steve Kerr — who played for Popovich — also defended the franchise's actions.

"If the NBA punishes the Spurs for sitting players, it opens up a huge can of worms," he wrote on Twitter. "This is a serious legal challenge for the league."

Celtics coach Doc Rivers didn't think the penalty would keep teams from resting players.

"I don't like it," he said. "It's a tough one. You've got to coach your team to win in the long run and you have to do whatever you need to do. If that's sitting players, you sit players."

That San Antonio — largely unloved in its championship days but suddenly a plucky underdog cheered by those who felt Stern overstepped his bounds — nearly won the game before the Heat rallied for a 105-100 victory didn't sway the commissioner.

The league has an expectation that fans paying hundreds of dollars should get what they paid for. On Friday, the Phoenix Suns announced a "satisfaction guaranteed night" next Thursday against Dallas, offering fans a rebate if they didn't enjoy their experience in what the team called a first-of-its-kind promotion in the league.

But nobody buying a ticket can be assured of seeing his favorite players. The Heat occasionally sat their superstars late last season for what the organization termed a "maintenance program," and a late-season matchup against the Celtics included the following DNPs: James, Wade, Bosh and Boston's Ray Allen, Kevin Garnett and Rajon Rondo.

Then there are the neutral-site preseason games the league stages in markets where fans rarely get to see the NBA live. Signs outside the Times Union Center in Albany, N.Y. before a Celtics-Knicks matchup in October featured pictures of Paul Pierce and Carmelo Anthony, although neither played despite being healthy.

With Stern reaching in now, does he reach that far? Or are there be a separate set of guidelines depending on the calendar?

The league wouldn't clear that up, not commenting beyond its statement. The Spurs were unavailable Friday after the long trip.

They were resting.

Hockey Coaches Defy Doctors on Concussions, Study Finds

Despite several years of intensive research, coverage and discussion about the dangers of concussions, the idea of playing through head injuries is so deeply rooted in hockey culture that two university teams kept concussed players on the ice even though they were taking part in a major concussion study.

The study, which was published Friday in a series of articles in the journal Neurosurgical Focus, was conducted during the 2011-12 hockey season by researchers from the University of Western Ontario, the University of Montreal, Harvard and other institutions.

“This culture is entrenched at all levels of hockey, from peewee to university,” said Dr. Paul S. Echlin, a concussion specialist and researcher in Burlington, Ontario, and the lead author of the study. “Concussion is a significant public health issue that requires a generational shift. As with smoking or seat belts, it doesn’t just happen overnight — it takes a massive effort and collective movement.”

The study is believed to be among the most comprehensive analyses of concussions in hockey, which has a rate of head trauma approaching that of football. Researchers followed two Canadian university teams — a men’s team and a women’s team — and scanned every player’s brain before and after the season. Players who sustained head injuries also received scans at three intervals after the injuries, with researchers using advanced magnetic resonance imaging techniques.

The teams were not named in the study, in which an independent specialist physician was present at each game and was empowered to pull any player off the ice for examination if a potential concussion was observed.

The men’s team, with 25 players and an average age of 22, played a 28-game regular season and a 3-game postseason. The women’s team, with 20 players and an average age of 20, played 24 regular-season games and no playoff games. Over the course of the season, there were five observed or self-reported concussions on the men’s team and six on the women’s team.

Researchers noted several instances of coaches, trainers and players avoiding examinations, ignoring medical advice or otherwise obstructing the study, even though the players had signed consent forms to participate and university ethics officials had given institutional consent.

“Unless something is broken, I want them out playing,” one coach said, according to the study.

In one incident, a neurologist observing the men’s team pulled a defenseman during the first period of a game after the player took two hits and was skating slowly. During the intermission the player reported dizziness and was advised to sit out, but the coach suggested he play the second period and “skate it off.” The defenseman stumbled through the rest of the game.

“At the end of the third period, I spoke with the player and the trainer and said that he should not play until he was formally evaluated and underwent the formal return-to-play protocol,” the neurologist said, as reported in the study. “I was dismayed to see that he played the next evening.”

After the team returned from its trip, the neurologist questioned the trainer about overruling his advice and placing the defenseman at risk.

“The trainer responded that he and the player did not understand the decision and that most of the team did not trust the neurologist,” according to the study. “He requested that the physician no longer be used to cover any more games.”

In another episode, a physician observer assessed a minor concussion in a female player and recommended that she miss the next night’s game. Even though the coach’s own playing career had ended because of concussions, she overrode the medical advice and inserted the player the next evening.

According to the report, the coach refused to speak to another physician observer on the second evening. The trainer was reluctant to press the issue with the coach because, the trainer said, the coach did not want the study to interfere with the team.

General Assembly Grants Palestine Upgraded Status in U.N.

Chang W. Lee/The New York Times

President Mahmoud Abbas of the Palestinian Authority spoke at the United Nations before the General Assembly voted on Palestine's status as a “nonmember observer state” on Thursday.

UNITED NATIONS — More than 130 countries voted on Thursday to upgrade Palestine to a nonmember observer state of the United Nations, a triumph for Palestinian diplomacy and a sharp rebuke to the United States and Israel.

But the vote, at least for now, did little to bring either the Palestinians or the Israelis closer to the goal they claim to seek: two states living side by side, or increased Palestinian unity. Israel and the militant group Hamas both responded critically to the day’s events, though for different reasons.

The new status will give the Palestinians more tools to challenge Israel in international legal forums for its occupation activities in the West Bank, including settlement-building, and it helped bolster the Palestinian Authority, weakened after eight days of battle between its rival Hamas and Israel.

But even as a small but determined crowd of 2,000 celebrated in central Ramallah in the West Bank, waving flags and dancing, there was an underlying sense of concerned resignation.

“I hope this is good,” said Munir Shafie, 36, an electrical engineer who was there. “But how are we going to benefit?”

Still, the General Assembly vote — 138 countries in favor, 9 opposed and 41 abstaining — showed impressive backing for the Palestinians at a difficult time. It was taken on the 65th anniversary of the vote to divide the former British mandate of Palestine into two states, one Jewish and one Arab, a vote Israel considers the international seal of approval for its birth.

The past two years of Arab uprisings have marginalized the Palestinian cause to some extent as nations that focused their political aspirations on the Palestinian struggle have turned inward. The vote on Thursday, coming so soon after the Gaza fighting, put the Palestinians again — if briefly, perhaps — at the center of international discussion.

“The question is, where do we go from here and what does it mean?” Salam Fayyad, the Palestinian prime minister, who was in New York for the vote, said in an interview. “The sooner the tough rhetoric of this can subside and the more this is viewed as a logical consequence of many years of failure to move the process forward, the better.” He said nothing would change without deep American involvement.

President Mahmoud Abbas of the Palestinian Authority, speaking to the assembly’s member nations, said, “The General Assembly is called upon today to issue a birth certificate of the reality of the state of Palestine,” and he condemned what he called Israeli racism and colonialism. His remarks seemed aimed in part at Israel and in part at Hamas. But both quickly attacked him for the parts they found offensive.

“The world watched a defamatory and venomous speech that was full of mendacious propaganda against the Israel Defense Forces and the citizens of Israel,” Prime Minister Benjamin Netanyahu of Israel responded. “Someone who wants peace does not talk in such a manner.”

While Hamas had officially backed the United Nations bid of Mr. Abbas, it quickly criticized his speech because the group does not recognize Israel.

“There are controversial issues in the points that Abbas raised, and Hamas has the right to preserve its position over them,” said Salah al-Bardaweel, a spokesman for Hamas in Gaza, on Thursday.

“We do not recognize Israel, nor the partition of Palestine, and Israel has no right in Palestine,” he added. “Getting our membership in the U.N. bodies is our natural right, but without giving up any inch of Palestine’s soil.”

Israel’s ambassador to the United Nations, Ron Prosor, spoke after Mr. Abbas and said he was concerned that the Palestinian Authority failed to recognize Israel for what it is.

“Three months ago, Israel’s prime minister stood in this very hall and extended his hand in peace to President Abbas,” Mr. Prosor said. “He reiterated that his goal was to create a solution of two states for two peoples, where a demilitarized Palestinian state will recognize Israel as a Jewish state.

“That’s right. Two states for two peoples. In fact, President Abbas, I did not hear you use the phrase ‘two states for two peoples’ this afternoon. In fact, I have never heard you say the phrase ‘two states for two peoples’ because the Palestinian leadership has never recognized that Israel is the nation-state of the Jewish people.”

The Israelis also say that the fact that Mr. Abbas is not welcome in Gaza, the Palestinian coastal enclave run by Hamas, from which he was ejected five years ago, shows that there is no viable Palestinian leadership living up to its obligations now.

Steelers QB Roethlisberger testing hurt shoulder

PITTSBURGH (AP) — Ben Roethlisberger can hold his newborn son Ben Jr. in his injured right arm just fine, thanks.

When the Pittsburgh Steelers quarterback will be able to say the same about a football, even he's not sure.

Roethlisberger practiced in a limited role Thursday and appears a long shot to return for Sunday's game in Baltimore.

"There's always a chance," Roethlisberger offered somewhat hopefully.

The lengthy list of issues still plaguing Roethlisberger more than two weeks after he sprained his right shoulder and suffered a dislocated rib in a 16-13 overtime win against Kansas City, however, suggests he's still a week away from giving it a go.

Though the pain isn't quite as intense as it was in the days after Kansas City linebacker Tamba Hali drilled Roethlisberger into the soggy Heinz Field turf, the two-time Super Bowl winner can still only sleep in certain positions at night. And while he's tested the shoulder this week, he's uncertain if he can make all the throws necessary to attack Baltimore's secondary.

"Can I put a lot of zip on the ball, throw it really hard before people like Ed Reed and defenders can get to the ball?" Roethlisberger said. "If I can't I'm not putting us in the best situation to win the game."

The Steelers (6-5) have struggled in Roethlisberger's absence, needing overtime to beat the woeful Chiefs before looking listless at times and sloppy at others in losses to Baltimore and Cleveland. A season that looked promising after a 24-20 win over the defending Super Bowl-champion Giants in New Jersey on Nov. 4 is suddenly on very shaky ground.

Still, don't expect Roethlisberger to push too quickly. It's something he's done in the past, with less than desired results. He played on a battered right ankle in San Francisco last year, limping around in a 20-3 loss. He ended up sitting out the next week and wasn't the same when he returned.

"We've had people talk about last year in San Francisco, if I would have rested maybe I would have been better off the next couple games but to me, I live for the here and now," he said. "I'm going to do everything I can to be out there and if it doesn't work then I'll do what I can about the next week."

Offensive coordinator Todd Haley said Roethlisberger threw "a little bit" on Thursday but the team continues to prepare as if Charlie Batch will make his second straight start. Batch completed 20 of 34 passes for 199 yards and three costly interceptions against the Browns, mistakes Haley attributed to rusty timing more than physical ability.

"I don't think there's any limitations to what Chuck can do," Haley said, "or needs to do with the guys we have."

Roethlisberger remains optimistic Batch can muster some of the magic that helped him lead the Steelers to three victories since 2010 while filling in for his good friend.

"I firmly believe that," Roethlisberger said. "They know what he's capable of. He's been doing it a long time. They respect him. I think he's ready to rise to the occasion."

Something the Steelers need to do if they want to build any momentum going into the final quarter of the season. A loss in a place they struggle to play well in — no matter who is behind the center — would leave them with no wiggle room whenever Roethlisberger gets back to work.

The game's importance is not lost on Roethlisberger, who will wear "juiced up" pads to protect his shoulder, though doctors have told him the dislocated rib no longer poses a threat to his aorta.

That's welcome news for a guy in the first days of fatherhood. Roethlisberger called being a dad "pretty cool" and while he's enjoyed the time at home, he's also eager to go back to his job. If he doesn't play on Sunday he'll do what he's done the last two weeks and stand on the sideline — earbuds in place — and provide the kind of insight Batch has imparted on him so many times though the years.

"It's hard for me," Roethlisberger said. "You watched me during these games. I've been on the field more than most of the coaches because I'm just antsy to get out there."

That anxiousness, however, figures to be around for at least another week.

___

NOTES: While Roethlisberger is doubtful, S Troy Polamalu appears ready to play for the first time since Oct. 7. Polamalu practiced for the second straight day and barring a setback should be on the field in Baltimore. Polamalu has been limited to just five quarters all season due to a strained right calf ... Rookie G David DeCastro continued to make progress in his first week on the active roster after recovering from right knee surgery in August. Haley said he expects DeCastro to make an impact on the field before the end of the season.

Clearing the Fog Around Personality Disorders

For years they have lived as orphans and outliers, a colony of misfit characters on their own island: the bizarre one and the needy one, the untrusting and the crooked, the grandiose and the cowardly.

Their customs and rituals are as captivating as any tribe’s, and at least as mystifying. Every mental anthropologist who has visited their world seems to walk away with a different story, a new model to explain those strange behaviors.

This weekend the Board of Trustees of the American Psychiatric Association will vote on whether to adopt a new diagnostic system for some of the most serious, and striking, syndromes in medicine: personality disorders.

Personality disorders occupy a troublesome niche in psychiatry. The 10 recognized syndromes are fairly well represented on the self-help shelves of bookstores and include such well-known types as narcissistic personality disorder, avoidant personality disorder, as well as dependent and histrionic personalities.

But when full-blown, the disorders are difficult to characterize and treat, and doctors seldom do careful evaluations, missing or downplaying behavior patterns that underlie problems like depression and anxiety in millions of people.

The new proposal — part of the psychiatric association’s effort of many years to update its influential diagnostic manual — is intended to clarify these diagnoses and better integrate them into clinical practice, to extend and improve treatment. But the effort has run into so much opposition that it will probably be relegated to the back of the manual, if it’s allowed in at all.

Dr. David J. Kupfer, a professor of psychiatry at the University of Pittsburgh and chairman of the task force updating the manual, would not speculate on which way the vote might go: “All I can say is that personality disorders were one of the first things we tackled, but that doesn’t make it the easiest.”

The entire exercise has forced psychiatrists to confront one of the field’s most elementary, yet still unresolved, questions: What, exactly, is a personality problem?

Habits of Thought

It wasn’t supposed to be this difficult.

Personality problems aren’t exactly new or hidden. They play out in Greek mythology, from Narcissus to the sadistic Ares. They percolate through biblical stories of madmen, compulsives and charismatics. They are writ large across the 20th century, with its rogues’ gallery of vainglorious, murderous dictators.

Yet it turns out that producing precise, lasting definitions of extreme behavior patterns is exhausting work. It took more than a decade of observing patients before the German psychiatrist Emil Kraepelin could draw a clear line between psychotic disorders, like schizophrenia, and mood problems, like depression or bipolar disorder.

Likewise, Freud spent years formulating his theories on the origins of neurotic syndromes. And Freudian analysts were largely the ones who, in the early decades of the last century, described people with the sort of “confounded identities” that are now considered personality disorders.

Their problems were not periodic symptoms, like moodiness or panic attacks, but issues rooted in longstanding habits of thought and feeling — in who they were.

“These therapists saw people coming into treatment who looked well put-together on the surface but on the couch became very disorganized, very impaired,” said Mark F. Lenzenweger, a professor of psychology at the State University of New York at Binghamton. “They had problems that were neither psychotic nor neurotic. They represented something else altogether.”

Several prototypes soon began to emerge. “A pedantic sense of order is typical of the compulsive character,” wrote the Freudian analyst Wilhelm Reich in his 1933 book, “Character Analysis,” a groundbreaking text. “In both big and small things, he lives his life according to a preconceived, irrevocable pattern.”

Others coalesced too, most recognizable as extreme forms of everyday types: the narcissist, with his fragile, grandiose self-approval; the dependent, with her smothering clinginess; the histrionic, always in the thick of some drama, desperate to be the center of attention.

In the late 1970s, Ted Millon, scientific director of the Institute for Advanced Studies in Personology and Psychopathology, pulled together the bulk of the work on personality disorders, most of it descriptive, and turned it into a set of 10 standardized types for the American Psychiatric Association’s third diagnostic manual. Published in 1980, it is a best seller among mental health workers worldwide.

These diagnostic criteria held up well for years and led to improved treatments for some people, like those with borderline personality disorder. Borderline is characterized by an extreme neediness and urges to harm oneself, often including thoughts of suicide. Many who seek help for depression also turn out to have borderline patterns, making their mood problems resistant to the usual therapies, like antidepressant drugs.

Today there are several approaches that can relieve borderline symptoms and one that, in numerous studies, has reduced hospitalizations and helped aid recovery: dialectical behavior therapy.

This progress notwithstanding, many in the field began to argue that the diagnostic catalog needed a rewrite. For one thing, some of the categories overlapped, and troubled people often got two or more personality diagnoses. “Personality Disorder-Not Otherwise Specified,” a catchall label meaning little more than “this person has problems” became the most common of the diagnoses.

It’s a murky area, and in recent years many therapists didn’t have the time or training to evaluate personality on top of everything else. The assessment interviews can last hours, and treatments for most of the disorders involve longer-term, specialized talk therapy.

Psychiatry was failing the sort of patients that no other field could possibly help, many experts said.

“The diagnoses simply weren’t being used very much, and there was a real need to make the whole system much more accessible,” Dr. Lenzenweger said.

Resisting Simplification 

It was easier said than done.

The most central, memorable, and knowable element of any person — personality — still defies any consensus.

A team of experts appointed by the psychiatric association has worked for more than five years to find some unifying system of diagnosis for personality problems.

The panel proposed a system based in part on a failure to “develop a coherent sense of self or identity.” Not good enough, some psychiatric theorists said.

Later, the experts tied elements of the disorders to distortions in basic traits.

This article has been revised to reflect the following correction:

An earlier version of this article misstated the number of traits included in the proposed criteria for narcissistic personality disorder.   The final proposal relies on two personality traits, not four.

DealBook: Vinod Khosla Keeps Long-Term Bet on Clean Technology

Vinod Khosla crowed about the clean energy industry last year. Three of the biofuel start-ups in his venture capital portfolio had just gone public, and the stocks had risen considerably after their debuts. “I challenge anybody to claim that clean tech done right is a disaster,” Mr. Khosla said at a conference, rebuffing recent criticism. “We’ve generated more profits there than anybody has.”

Since then, Mr. Khosla, the founder of Khosla Ventures, has watched much of those paper gains evaporate. As the clean energy industry broadly has taken a hit, shares of the biofuel companies — Amyris, Gevo and KiOR — have slumped 70 percent to 90 percent from their peaks. His stakes, once worth as much as $1.3 billion, are now valued at roughly $378 million.

The billionaire investor has been caught in the cyclical downdraft.

The public stocks of solar, wind and biofuel companies are suffering amid industrywide pressures. The price of natural gas remains low. Europe has pulled back on incentives. American subsidies are in question after the bankruptcy of the solar panel maker Solyndra. And China is providing formidable low-cost competition.

“The whole clean tech sector has been out of favor,” said Pavel Molchanov, an analyst at Raymond James & Associates, a brokerage firm. “I’d be hard pressed to name one trading above its I.P.O. price.”

Despite the crosscurrents, Mr. Khosla seems unwavering in his commitment. He is pouring money into start-ups. Khosla Ventures recently invested more in LightSail Energy, a three-year-old start-up working to develop low-cost energy storage. He is also sticking with his public companies. His firm, for example, still owns 54 percent of KiOR.

“He’s a visionary who likes to make big bets on ideas that can really change the world,” said Andy Bechtolsheim, who co-founded Sun Microsystems with Mr. Khosla 30 years ago and shares a house with him at Big Sur on the California coast. “I would think he’s made a larger personal bet on green tech than anybody else.”

While the public markets are raising short-term doubts, the long-term investment thinking remains unchanged. Governments around the globe are pushing to find alternative sources of energy in an effort to reduce their dependence on fossil fuels that may hurt the environment. In a television interview in 2007, Mr. Khosla said “mainstream solutions” could replace up to 80 percent of oil-based power. Without them, he said, “this planet is history the way we know it today.” After Hurricane Sandy, the subject of global warming — and changing climate conditions — has again come to the forefront.

In a recent blog post on the Forbes Web site, Mr. Khosla acknowledged the shift in market sentiment. “Clean tech went through a time when it was in vogue and now it is not,” he wrote. “The financing environment for clean tech companies is tough today,” he added. But he said he still expected “to do better than industry averages by keeping our losing companies to a minority.”

Since founding his venture capital firm in 2004, Mr. Khosla has become one of the most vocal advocates for clean tech innovation, buying stakes in about 60 industry start-ups. Ausra, a solar thermal start-up that had drawn $130 million in venture backing, was sold in 2010 to the French nuclear plant builder Areva for about $250 million, according to one industry estimate. And SeaMicro, a low-power server maker, was bought this year by Advanced Micro Devices for $334 million, more than five times the amount invested by its venture backers, according to a SeaMicro co-founder, Andrew Feldman.

It’s unclear how the broader clean tech portfolio has performed at Khosla Ventures. Mr. Khosla declined to disclose the firm’s returns or to comment for the article.

But one of his funds, which raised $1 billion to invest in clean tech and other start-ups, shows gain of 30 percent since its inception in 2009, according to filings by the California Public Employees’ Retirement System, the largest state pension fund. In his Forbes blog post, Mr. Khosla said a recent fund, which raised $1.05 billion in October 2011, was oversubscribed, and his firm’s broader performance since 2006 had “well exceeded typical venture funds.” In that period, venture funds over all have returned 7.25 percent annually after fees, according to industry data.

Mr. Khosla’s commitment is an outgrowth of his three decades at the cutting edge of technology.

A native of India, Mr. Khosla, 57, earned a master’s degree in biomedical engineering from Carnegie Mellon and an M.B.A. from Stanford in 1980. After starting the design automation company Daisy Systems in 1982, he co-founded Sun Microsystems, then a growing technology company.

At Sun, he supplied drive and vision. But Mr. Khosla, who is known for his blunt talk and intense manner, was replaced as chief executive two years later and left the company shortly thereafter.

In 1986, he joined the venture capital firm Kleiner Perkins Caufield & Byers. Over the next two decades, Mr. Khosla scored sizable returns betting on the growth of fiber optic networks. Two companies, Cerent and Siara Systems, were sold for a combined $15 billion-plus at the height of the late-1990s dot-com bubble.

Mr. Khosla was looking into alternative fuel technologies at Kleiner Perkins when a business plan for an ethanol start-up crossed his desk in 2003. The plan “sat on a corner of my desk for nearly 18 months while I read everything I could about petroleum and its alternatives,” he wrote in an article for Wired magazine in 2006.

When he branched out on his own in 2004, Mr. Khosla invested millions in the ethanol start-up, Celunol. He soon established himself as a top venture capitalist in clean tech, attracting prominent outside investors like Microsoft’s founder, Bill Gates. Former Prime Minister Tony Blair of Britain joined the firm as a senior adviser.

Over the years, Mr. Khosla has experienced his share of blowups.

In September 2011, Khosla-backed Range Fuels, a wood-chips-to-ethanol company, went bankrupt after receiving a $44 million grant from the Department of Energy and $33 million under a Department of Agriculture loan guarantee. When The Wall Street Journal editorial page criticized Range Fuels as an “exercise in corporate welfare,” Mr. Khosla lashed back, saying the authors inhabited an “ivory tower” that was “full of people who don’t understand technology.”

Sometimes, Mr. Khosla’s companies had to pivot from their original plans and focus on new markets. For example, Calera was founded in 2007 with plans to use power plant exhaust to make cement. Mr. Khosla called its technology “game changing” in 2008.

But the company encountered some setbacks. It postponed plans for commercial-scale production in 2010 pending further research and later cut its 145-employee work force by two-thirds. Since then, Calera has broadened its focus, developing other products like fillers for paper and plastics.

Like many venture capital investors, Mr. Khosla will risk a few strikeouts for the chance to hit home runs. “My willingness to fail is what gives me the ability to succeed,” the investor has said frequently.

The odds can be especially brutal in clean technology. The projects are often capital-intensive — like $200 million or more for a biofuels plant — and they can take years to pay out, said Sam Shelton, a research engineer at Georgia Institute of Technology. By comparison, social media start-ups often require little upfront money and few employees. “The economics are totally different,” Mr. Shelton said.

In part, Mr. Khosla aims to take stakes when the companies are still getting off the ground, rather than waiting until they’re more mature and more expensive. He first bought a stake in KiOR, which aims to convert wood chips to gas and diesel fuel, in 2007. The company is now completing the first of five planned plants in Mississippi with the help of a $75 million interest-free loan from the state.

Mr. Khosla is “always thinking at a very high level about the potential of an idea,” KiOR’s chief executive, Fred Cannon, said. “He has a very good feel for when to step on the gas.”

After jumping in early, Mr. Khosla appears willing to ride out the swings, in both directions. Over the years, public filings indicate he has plowed roughly $80 million into KiOR, amassing a 54 percent stake in the company. Although the stock is off its peak levels and I.P.O. investors are still underwater, his holdings are worth $356 million — a threefold gain.

Correction: November 30, 2012

An earlier version of this article mischaracterized Mr. Khosla's return on his investment in KiOR. He invested roughly $80 million and his holdings are worth $356 million — a threefold gain, not a fourfold gain.

Rebels celebrated on top of a downed Syrian jet in Daret Azzeh, 20 miles west of Aleppo, on Wednesday.

In its first major effort to show that it can be a viable political force, the newly formed Syrian opposition coalition started talks in Egypt on Wednesday aimed at forming an alternative to the government of President Bashar al-Assad and paving the way for more international acceptance and aid.

The coalition, whose official name is the National Coalition of Syrian Revolutionary and Opposition Forces, was formed at a meeting in Qatar this month and has been recognized by Britain, France, Turkey and the Gulf Cooperation Council. To win further support from foreign capitals, it must tackle the broader problems of uniting the many opposition groups in exile and the rebels on the ground in Syria.

Delegates were expected to hold their second day of talks in a Cairo hotel on Thursday against the backdrop of a 20-month civil war in which about 40,000 people have been killed in clashes between armed rebels and jihadist fighters on one side and Mr. Assad’s forces on the other. The rebels appear to be gaining in their strategy to challenge the air supremacy of Mr. Assad’s military.

There were reports on Wednesday that for the second successive day, insurgents had shot down a government aircraft. Video posted on the Internet by rebels showed an airplane tail assembly jutting out of debris. Such videos are difficult to verify, but the episode on Wednesday seemed to be confirmed by other witnesses.

“We watched a Syrian plane being shot down as it was flying low to drop bombs” on the town of Daret Azzeh, 20 miles west of Aleppo and close to the Turkish border, said Ugur Cuneydioglu, who said he saw the aircraft being downed from a Turkish border village in southern Hatay Province. “It slowly went down in flames before it hit the ground. It was quite a scene,” Mr. Cuneydioglu said.

The video said the plane had been brought down by “the free men of Daret Azzeh soldiers of God brigade.”

On Tuesday, Syrian rebels said they shot down a military helicopter with a surface-to-air missile outside Aleppo.

The violence on Wednesday also included car bombs in a Damascus suburb that killed dozens of people.

In their first meeting since their umbrella organization was created in Doha, Qatar, on Nov. 11, coalition delegates confronted the realities of the political terrain. Disagreements emerged over the coalition’s composition when one member, the Syrian National Council, tried to increase the number of its representatives.

“Nothing will proceed until we work this out,” said one council member who spoke on condition of anonymity, according to Reuters.

The focus also seemed to be more on deciding how leadership candidates should be chosen rather than on who they might be. “I don’t think we’ll be discussing the election of a transitional government during the meeting today,” said Khaled Khoja, a coalition member. “We’re still discussing whether to have a government or to have committees instead.”

While the group, and the talks, are in their infancy, members appeared to recognize that world supporters were watching for results. Mr. Khoja said that while the group was discussing the coalition’s structure, it wanted to “see the outcome of the meeting in Morocco before deciding on the government.”

He was referring to a meeting planned for next month in Morocco of the so-called Friends of Syria group of nations, which includes the United States. At a meeting in New York City in September that included foreign ministers and Syrian opposition leaders, the group offered modest pledges of support for opponents of the Assad government. The opposition had unified under international pressure to give provinces better representation, and ideally, to oversee the disparate rebel factions while also providing a counterweight to the well-armed jihadist groups in the country.

The conflict has also flared along Syria’s borders with Lebanon, Israel, Turkey and Jordan.

In Turkey, which was once an ally of the Assad government, a team of NATO inspectors visited sites on Wednesday where the alliance might install batteries of Patriot antiaircraft missiles.

Another video on Wednesday showed a rebel fighter holding what appeared to be a complete SA-16 heat-seeking, shoulder-fired missile.

The man claimed to have shot down both the airplane and the helicopter, and said the missiles had been captured by rebels when they overran Base 46 outside Aleppo earlier this month.

High-profile tactical successes in the war have often been followed by videotaped claims of responsibility, and in part are seen as fund-raising opportunities for the fighters. Many claims, including those by the rebel fighters, are impossible to verify immediately.

But it was significant. The SA-16 is more modern and capable than the more commonly seen SA-7. It flies at a faster speed, can be used against aircraft at much wider range of attack angles, has a longer range and is promoted by its Russian exporters as being more resistant to an aircraft’s efforts to thwart it.

Its presence suggested that the rebels have been acquiring more weapons and could be mounting a more meaningful challenge to the Syrian Air Force.

State news media said on Wednesday that two car bombings struck Jaramana, a suburb of Damascus that is populated by members of the Christian and Druse minorities.

The SANA news agency said the death toll was at least 34. An activist group based in Britain, the Syrian Observatory for Human Rights, said 47 people were killed.

Obama takes “fiscal cliff” battle to Twitter

WASHINGTON (Reuters) – President Barack Obama opened a new front on Wednesday in the battle between Democrats and Republicans over the best way to avoid the year-end “fiscal cliff” – Twitter.

The web-savvy Obama administration launched a social media campaign that asks Twitter users to add the “#my2k” hashtag to messages with examples of what $ 2,000 means to them.

The amount is roughly what a middle-class family of four would have to pay extra in taxes next year if Congress cannot strike a deal to remove the threat of roughly $ 600 billion in tax hikes and federal spending cuts.

The fast-paced social networking site known for its zippy 140-character comments is a tried-and-true method of reaching Americans. The latest call for such searchable references is an effort to pressure Congress into finding compromise on long-held partisan views.

Obama announced the new Twitter hashtag campaign at a news conference on Wednesday. He and fellow Democrats, who oppose significant cuts to U.S. “entitlement” programs such as Medicare as a way of balancing the budget, have been trying to break Republican opposition to hiking taxes on anyone, including the wealthy.

Promotions of “#my2k” quickly went out to millions of followers of the White House Twitter account and scores of Democratic backers, including former House of Representatives Speaker Nancy Pelosi. Soon, “my2k” was a top-trending subject.

“#My2K means food for a year, the remainder of my student loan paid off or a full month of child care. $ 2200 can make or break a family,” wrote Twitter user Katrina Burchett.

In the anarchic spirit of social media, Republicans, who also polished their Twitter hashtag skills during the bitter 2012 presidential campaign, pounced quickly.

The conservative Heritage Foundation bought the promotional tweet that pops up at the top of the list if one searches for “#my2k” mentions, where the think tank offered its own take on solutions to the fiscal cliff.

House Speaker John Boehner and scores of fellow Republican lawmakers started sharing examples they hoped would put the blame for the lack of a resolution on the Democrats.

“We in the House took steps this summer to avert #fiscalcliff and stop #my2K tax hikes,” wrote Representative Mike Turner. “It’s time for @whitehouse and @SenateDems to act.”

‘BEING AWARE OF WHAT’S GOING ON’

Users on Twitter can sign up to follow one another’s messages, making searchable hashtags a helpful way to sort by subject or theme.

Marcus Messner, who studies social media at Virginia Commonwealth University, said Twitter was a perfect environment to reignite Obama’s base swiftly and gauge public engagement on the issue.

The Obama administration has used Twitter hashtags as part of lobbying campaigns to keep student loan rates low with #dontdoublemyrate and to extend payroll tax cuts with #40dollars, which was their estimate of how much the cuts saved an average family each year.

White House Social Media Director Macon Phillips later called the $ 40dollars hashtag “one of the most significant campaigns we ran on Twitter.”

“It’s about being aware of what’s going on and understanding that in the age of social media, you’re just a participant,” he told an Entrepreneur.com blogger in February. “It’s not something that you can control.”

Bonds, Clemens, Sosa on Hall ballot for first time

NEW YORK (AP) — The most polarizing Hall of Fame debate since Pete Rose will now be decided by the baseball shrine's voters: Do Barry Bonds, Roger Clemens and Sammy Sosa belong in Cooperstown despite drug allegations that tainted their huge numbers?

In a monthlong election sure to become a referendum on the Steroids Era, the Hall ballot was released Wednesday, and Bonds, Clemens and Sosa are on it for the first time.

Bonds is the all-time home run champion with 762 and won a record seven MVP awards. Clemens took home a record seven Cy Young trophies and is ninth with 354 victories. Sosa ranks eighth on the homer chart with 609.

Yet for all their HRs, RBIs and Ws, the shadow of PEDs looms large.

"You could see for years that this particular ballot was going to be controversial and divisive to an unprecedented extent," Larry Stone of The Seattle Times wrote in an email. "My hope is that some clarity begins to emerge over the Hall of Fame status of those linked to performance-enhancing drugs. But I doubt it."

More than 600 longtime members of the Baseball Writers' Association of America will vote on the 37-player ballot. Candidates require 75 percent for induction, and the results will be announced Jan. 9.

Craig Biggio, Mike Piazza and Curt Schilling also are among the 24 first-time eligibles. Jack Morris, Jeff Bagwell and Tim Raines are the top holdover candidates.

If recent history is any indication, the odds are solidly stacked against Bonds, Clemens and Sosa. Mark McGwire and Rafael Palmeiro both posted Cooperstown-caliber stats, too, but drug clouds doomed them in Hall voting.

Some who favor Bonds and Clemens claim the bulk of their accomplishments came before baseball got wrapped up in drug scandals. They add that PED use was so prevalent in the 1980s, 1990s and early 2000s that it's unfair to exclude anyone because so many who-did-and-who-didn't questions remain.

Many fans on the other side say drug cheats — suspected or otherwise — should never be afforded the game's highest individual honor.

Either way, this election is baseball's newest hot button, generating the most fervent Hall arguments since Rose. The discussion about Rose was moot, however — the game's career hits leader agreed to a lifetime ban in 1989 after an investigation concluded he bet on games while managing the Cincinnati Reds, and that barred him from the BBWAA ballot.

The BBWAA election rules allow voters to pick up to 10 candidates. As for criteria, this is the only instruction: "Voting shall be based upon the player's record, playing ability, integrity, sportsmanship, character, and contributions to the team(s) on which the player played."

That leaves a lot of room for interpretation.

Bonds, Clemens and Sosa won't get a vote from Mike Klis of The Denver Post.

"Nay on all three. I think in all three cases, their performances were artificially enhanced. Especially in the cases of Bonds and Clemens, their production went up abnormally late in their careers," he wrote in an email.

They'll do better with Bob Dutton of The Kansas City Star.

"I plan to vote for all three. I understand the steroid/PED questions surrounding each one, and I've wrestled with the implications," he wrote in an email.

"My view is these guys played and posted Hall of Fame-type numbers against the competition of their time. That will be my sole yardstick. If Major League Baseball took no action against a player during his career for alleged or suspected steroid/PED use, I'm not going to do so in assessing their career for the Hall of Fame," he said.

San Jose Mercury News columnist Mark Purdy will reserve judgment.

"At the beginning of all this, I made up my mind I had to adopt a consistent policy on the steroid social club. So, my policy has been, with the brilliance in the way they set up the Hall of Fame vote where these guys have a 15-year window, I'm not going to vote for any of those guys until I get the best picture possible of what was happening then," he wrote in an email.

"We learn a little bit more each year. We learned a lot during the Bonds trial. We learned a lot during the Clemens trial. I don't want to say I'm never going to vote for any of them. I want to wait until the end of their eligibility window and have my best idea of what was really going on," he said.

Clemens was acquitted this summer in federal court on six counts that he lied and obstructed Congress when he denied using performance-enhancing drugs.

Bonds was found guilty in 2011 by a federal court jury on one count of obstruction of justice, ruling he gave an evasive answer in 2003 to a grand jury looking into the distribution of illegal steroids. Bonds is appealing the verdict.

McGwire is 10th on the career home run list with 583, but has never received even 24 percent in his six Hall tries. Big Mac has admitted to using steroids and human growth hormone.

Palmeiro is among only four players with 500 homers and 3,000 hits, yet has gotten a high of just 12.6 percent in his two years on the ballot. He drew a 10-day suspension in 2005 after a positive test for PEDs, and said the result was due to a vitamin vial given to him by teammate Miguel Tejada.

Biggio topped the 3,000-hit mark — which always has been considered an automatic credential for Cooperstown — and spent his entire career with the Houston Astros.

"Hopefully, the writers feel strongly that they liked what they saw, and we'll see what happens," Biggio said last week.

Schilling was 216-146 and won three World Series championships, including his "bloody sock" performance for the Boston Red Sox in 2004.

Well: Weight Loss Surgery May Not Combat Diabetes Long-Term

Weight loss surgery, which in recent years has been seen as an increasingly attractive option for treating Type 2 diabetes, may not be as effective against the disease as it was initially thought to be, according to a new report. The study found that many obese Type 2 diabetics who undergo gastric bypass surgery do not experience a remission of their disease, and of those that do, about a third redevelop diabetes within five years of their operation.

The findings contrast with the growing perception that surgery is essentially a cure for Type II diabetes. Earlier this year, two widely publicized studies reported that surgery worked better than drugs, diet and exercise in causing a remission of Type 2 diabetes in overweight people whose blood sugar was out of control, leading some experts to call for greater use of surgery in treating the disease. But the studies were small and relatively short, lasting under two years.

The latest study, published in the journal Obesity Surgery, tracked thousands of diabetics who had gastric bypass surgery for more than a decade. It found that many people whose diabetes at first went away were likely to have it return. While weight regain is a common problem among those who undergo bariatric surgery, regaining lost weight did not appear to be the cause of diabetes relapse. Instead, the study found that people whose diabetes was most severe or in its later stages when they had surgery were more likely to have a relapse, regardless of whether they regained weight.

“Some people are under the impression that you have surgery and you’re cured,” said Dr. Vivian Fonseca, the president for medicine and science for the American Diabetes Association, who was not involved in the study. “There have been a lot of claims about how wonderful surgery is for diabetes, and I think this offers a more realistic picture.”

The findings suggest that weight loss surgery may be most effective for treating diabetes in those whose disease is not very advanced. “What we’re learning is that not all diabetic patients do as well as others,” said Dr. David E. Arterburn, the lead author of the study and an associate investigator at the Group Health Research Institute in Seattle. “Those who are early in diabetes seem to do the best, which makes a case for potentially earlier intervention.”

One of the strengths of the new study was that it involved thousands of patients enrolled in three large health plans in California and Minnesota, allowing detailed tracking over many years. All told, 4,434 adult diabetics were followed between 1995 and 2008. All were obese, and all underwent Roux-en-Y operations, the most popular type of gastric bypass procedure.

After surgery, about 68 percent of patients experienced a complete remission of their diabetes. But within five years, 35 percent of those patients had it return. Taken together, that means that most of the subjects in the study, about 56 percent — a figure that includes those whose disease never remitted — had no long-lasting remission of diabetes after surgery.

The researchers found that three factors were particularly good predictors of who was likely to have a relapse of diabetes. If patients, before surgery, had a relatively long duration of diabetes, had poor control of their blood sugar, or were taking insulin, then they were least likely to benefit from gastric bypass. A patient’s weight, either before or after surgery, was not correlated with their likelihood of remission or relapse.

In Type 2 diabetes, the beta cells that produce insulin in the pancreas tend to wear out as the disease progresses, which may explain why some people benefit less from surgery. “If someone is too far advanced in their diabetes, where their pancreas is frankly toward the latter stages of being able to produce insulin, then even after losing a bunch of weight their body may not be able to produce enough insulin to control their blood sugar,” Dr. Arterburn said.

Nonetheless, he said it might be the case that obese diabetics, even those whose disease is advanced, can still benefit from gastric surgery, at least as far as their quality of life and their risk factors for heart disease and other complications are concerned.

“It’s not a surefire cure for everyone,” he said. “But almost universally, patients lose weight after weight loss surgery, and that in and of itself may have so many health benefits.”
