Can Social Media Help You Lose Weight?

At the start of the New Year, when weight loss is often a priority, building a support team to help keep us on track can be extremely helpful. This might typically consist of family members, friends, co-workers, or perhaps even a nutritionist or registered dietitian. But today, support can also be found online. Plenty of Web sites focus on losing weight, and include communities that provide support and encouragement. Since many of us spend a lot of time on social media sites–maybe too much if you ask my husband!–why not use these platforms as another tool for support? In fact, one study suggests employees participating in a workplace wellness program who also joined the company’s Facebook page, run by a registered dietitian, stayed with the program longer than those who didn’t.

[See Already Struggling With Your New Year's Resolution?]

Could it actually make sense that gluing ourselves to our mobile device or computer could help us shed pounds? It sounds like quite the oxymoron, since increased screen time doesn’t usually equate to weight loss. But here’s how to make social media sites work for you:

Facebook

Facebook is a place where you can share what’s going on in your life with friends, but you may not feel comfortable announcing what you weigh or that you’re trying to lose weight. On the other hand, you may enjoy posting fitness milestones, such as training for and completing your first marathon, or a bike ride for your favorite charity. Sharing your fitness goals with the Facebook universe may be helpful, because the more people who know about it, the more likely you are to stay committed.

Rather than simply connecting with friends on the site, you can also connect with health and fitness professionals, such as registered dietitians, or pages for diet books, like mine, The Small Change Diet. You can also “like” the pages of health and fitness magazines and your favorite brands. The folks who run these pages may post articles that provide you with helpful weight-loss tips, and many organize regular Facebook chats, allowing you to ask an expert your questions. The more that healthy information is “in your face,” the more likely you are to stick to it.

Most importantly, you may discover a weight-loss community on Facebook, where like-minded individuals share their weight losses (or gains) and offer support. Daily accountability could be just what you need, and knowing others are rooting for you can make a world of difference. If you can’t find a Facebook community you like, start your own.

Twitter

So many of my patients don’t have Twitter accounts, because they think they have nothing clever or witty to say. My advice to them is always the same: You don’t have to “say” anything; you can just follow, at least at the beginning. Registered dietitians (I’m @kerigans) have great tips and, if they’re like me, are more than happy to answer questions via Twitter. I’ve had followers tweet a picture of their dinner and ask what my dietitian colleagues and I thought of it–priceless information for free.

[See Best Plant-Based Diets]

Just as you do on Facebook, follow fitness professionals, health magazines, and other sources that provide weight-loss motivation. Once you feel comfortable, you may decide to join in the conversation, since that’s what social media is all about. Perfect example of how it can benefit you: One morning, I tweeted that I felt more like staying in my pajamas than going to yoga. Some of my followers chimed in that they were feeling the same way, BUT stressed that we should all still exercise. And so we all did. And trust me, none of us regretted going–rather, we were thankful for each other.

[See Are Mobile Health Apps Helpful?]

Seek out people on Twitter and Facebook who you find inspirational, and hopefully a little of what they do will rub off on you. Since nothing is etched in stone, you can unfollow, unlike, or unfriend them if they aren’t helping you. And please keep in mind that while social media can be another tool in your pursuit of weight loss, it’s not the end all. Healthy eating, fitness, and plenty of sleep actually need to happen away from a screen.

NFL star Junior Seau suffered from brain disease

Junior Seau, one of the NFL's best and fiercest players for two decades, suffered from a degenerative brain disease often associated with repeated blows to the head when he committed suicide last May, the National Institutes of Health said in a study released Thursday.

The NIH, based in Bethesda, Md., said Seau's brain revealed abnormalities consistent with chronic traumatic encephalopathy or CTE. It said that the study included unidentified brains, one of which was Seau's, and that the findings on Seau were similar to autopsies of people "with exposure to repetitive head injuries."

Seau's family requested the analysis of his brain.

The 43-year-old star linebacker played for 20 NFL seasons with San Diego, Miami and New England before retiring in 2009. He died of a self-inflicted shotgun wound.

He joins a list of several dozen football players who were found to have CTE. Boston University's center for study of the disease reported last month that 34 former pro players and nine who played only college football suffered from CTE.

"I was not surprised after learning a little about CTE that he had it," Seau's 23-year-old son Tyler said. "He did play so many years at that level. I was more just kind of angry I didn't do something more and have the awareness to help him more, and now it is too late.

"I don't think any of us were aware of the side effects that could be going on with head trauma until he passed away. We didn't know his behavior was from head trauma."

That behavior, according to Tyler Seau and Junior's ex-wife Gina, included wild mood swings, irrationality, forgetfulness, insomnia and depression.

The NFL faces lawsuits by thousands of former players who say the league withheld information on the harmful effects of concussions. According to an AP review of 175 lawsuits, 3,818 players have sued. At least 26 Hall of Famer members are among the players who have done so.

Seau is not the first former NFL player who killed himself, then was found to have CTE. Dave Duerson and Ray Easterling are the others.

"He emotionally detached himself and would kind of 'go away' for a little bit," Tyler Seau said. "And then the depression and things like that. It started to progressively get worse."

He hid it well in public, they said. But not when he was with family or close friends.

Dr. Russell Lonser, who oversaw the study, said Seau's brain was "independently evaluated by multiple experts, in a blind fashion."

"We had the opportunity to get multiple experts involved in a way they wouldn't be able to directly identify his tissue even if they knew he was one of the individuals studied," he said.

The National Football League, in an email to the AP, said: "We appreciate the Seau family's cooperation with the National Institutes of Health. The finding underscores the recognized need for additional research to accelerate a fuller understanding of CTE.

"The NFL, both directly and in partnership with the NIH, Centers for Disease Control and other leading organizations, is committed to supporting a wide range of independent medical and scientific research that will both address CTE and promote the long-term health and safety of athletes at all levels."

NFL teams have given a $30 million research grant to the NIH.

Before shooting himself, Duerson, a former Chicago Bears defensive back, left a note asking that his brain be studied for signs of trauma. His family filed a wrongful-death suit against the NFL, claiming the league didn't do enough to prevent or treat the concussions that severely damaged his brain.

Easterling played safety for the Falcons in the 1970s. After his career, he suffered from dementia, depression and insomnia, according to his wife, Mary Ann. He committed suicide last April.

Mary Ann Easterling is among the plaintiffs who have sued the NFL.

"It was important to us to get to the bottom of this, the truth," Gina Seau said, "and now that it has been conclusively determined from every expert that he had obviously had it, CTE, we just hope it is taken more seriously.

"You can't deny it exists, and it is hard to deny there is a link between head trauma and CTE. There's such strong evidence correlating head trauma and collisions and CTE."

Tyler Seau played football through high school and for two years in college. He says he has no symptoms of brain trauma.

Gina Seau's son Jake, now a high school junior, played football for two seasons but has switched to lacrosse and has been recruited to play at Duke.

"Lacrosse is really his sport and what he is passionate about," she said. "He is a good football player and probably could continue. But especially now watching what his dad went through, he says, 'Why would I risk lacrosse for football?'

"I didn't have to have a discussion with him after we saw what Junior went through."

Her 12-year-old son, Hunter, has shown no interest in playing football.

"That's fine with me," she said.

City Room: How Are You Warding Off the Flu?

Sure, you could go out and get a flu shot like everyone keeps telling you to do. It’s relatively cheap, and available just about everywhere.

But the shot is not 100 percent effective. And it takes two weeks to kick in. Although influenza can be deadly, some have been making light of the virus’s symptoms.

On the bright side, having the flu was a great start to my spring break diet.. eating nothing and still managing to puke

Sharp Words From European Minister for Countries in North

BRUSSELS — Jean-Claude Juncker, the departing leader of the group of ministers who oversee the euro currency, sharply criticized northern Europeans on Thursday for demanding austerity budgets from their southern neighbors.

But in the same speech he seemed to endorse as his successor an official from the Netherlands, one of countries that has made the toughest demands for fiscal rigor in the euro zone.

Mr. Juncker, himself a northern European and prime minister of Luxembourg, told members of the European Parliament’s influential Economic and Monetary Affairs Committee that northerners had falsely painted themselves as more economically virtuous than southerners. “I’m totally against this distinction,” he said.

Mr. Juncker warned that some members of his own country’s Parliament had become fed up with “the German diktat,” and he said countries making painful economic adjustments should be rewarded for their efforts.

“We have been arrogant” toward countries like Greece, he said.

Still, Mr. Juncker said his successor as head of the Eurogroup of ministers would speak one of the languages of the Benelux, a grouping that includes Belgium, the Netherlands and Luxembourg. Mr. Juncker’s comments were characteristically cryptic, but appeared to lend weight to the chances of the front-runner for the job, Jeroen Dijsselbloem, the Dutch finance minister.

The president of the Eurogroup plays a coordinating role among finance ministers when they make critical decisions like giving political approval for bailouts or pressuring governments to shore up their finances to preserve the stability of the euro. Mr. Juncker has held the post since 2005; although his term expired last summer, he indicated he would stay on for a limited time until a successor was named.

At a news conference Thursday, Mr. Juncker said a decision on his successor should be made on, or shortly after, Jan. 21, because that would be the last meeting of the Eurogroup at which he would serve as president.

Although the president of the Eurogroup is supposed to be elected by ministers, as a practical matter is decided by consensus among governments, opening the way for political horse-trading.

Mr. Dijsselbloem’s candidacy gained strength in recent weeks partly because he comes from a country that still holds a triple-A debt rating, making him a natural ally of Germany. But his candidacy is more problematic for the French, the other major power in the euro area.

The government led by President François Hollande has emphasized giving the most vulnerable members of the euro area the leeway to make painful economic adjustments. By contrast, the Netherlands, along with Germany and Finland, has pressed indebted nations like Greece and Portugal to tighten their belts, despite the recessionary effect on their economies.

One factor that could help the French swing in support of Mr. Dijsselbloem, a member of the Dutch Labor Party, is that he, like Mr. Hollande, is a socialist.

Meanwhile, for the soon-to-be created single banking supervisory agency for the euro zone, Mr. Juncker suggested Thursday that a Frenchwoman could be offered a senior role. And although Mr. Juncker again did not offer names, there are reports in the French news media that Danièle Nouy, an official at the Banque de France, could be offered such a role, partly to assuage French concerns.

Mr. Dijsselbloem, 46, won the finance portfolio, his first Netherlands cabinet post, late last year, and he has little experience at the top levels of government or in European affairs. But he did take office in time to participate in a round of marathon meetings by finance ministers to strike agreements on resuming aid to Greece and the creation of the single banking supervisor.

“I suppose he is suitable as he wouldn’t be finance minister,” said Sophie in ‘t Veld, a Dutch member of the European Parliament for the Democrats 66, a liberal and pro-European political party.

“But how is he going to navigate between the deeply euro-skeptic electorate and a deeply euro-skeptic Parliament that will expect him to be a troublemaker in Europe and, on the other hand, show compromise and consensus as the head of the Eurogroup?” she asked.

Mr. Dijsselbloem told the Dutch daily newspaper De Volkskrant at the end of December that he regarded “strengthening European cooperation inevitable and good for the Netherlands.” But he also cautioned that, “when it comes to Greece, for example, everyone looks to the Netherlands and we have to take the floor” and that, “from us, from Germany and Finland, it’s expected that we exhibit some strictness.”

That, though, is an approach that Mr. Juncker on Thursday cautioned his successor against taking. For countries like Greece and Portugal facing brutal austerity, he said, there should be rewards for meeting targets and “not only a big stick.”

Mr. Juncker also called for euro area countries to adopt a legal minimum wage so as not “to lose the support of the working classes.”

And in a marked contrast to the stance of some Dutch politicians, Mr. Juncker suggested that countries like Spain and Ireland should have some scope for using European bailout funds to bail out their banks directly. Otherwise, said Mr. Juncker, the purpose of the bailout fund “would lose a large part of its sense.”

For his part, Mr. Juncker said at the news conference that he would concentrate on winning another term as the prime minister of Luxembourg and use that perch to continue to play a role in European affairs.

“You will hear from me,” he said.

Global Update: China Moves to Prevent Spread of Yellow Fever From Africa

In a move that underlines how many Chinese citizens now work in Africa, China’s quarantine officials recently urged greater efforts to make sure that a yellow fever epidemic now raging in Sudan does not come back to China.

Local health authorities were asked to scan all travelers arriving from Sudan for fevers. Chinese citizens planning travel to Sudan were advised to get yellow fever shots. Customs officers were told that containers arriving from Sudan might have stray infected mosquitoes inside.

Sudan’s epidemic is considered the world’s worst in 20 years. Sweden, Britain and other donors have paid for vaccinations. The United States Navy’s laboratory in Egypt has helped with diagnoses.

Estimates of the number of Chinese working in Africa, many in the oil and mining industries or on major construction projects, range from 500,000 to 1 million. Experts on AIDS have previously warned that the workers could become a new means of bringing that disease to China, which has a low H.I.V.-infection rate.

ProMED-mail, a Web site that follows emerging diseases, has tracked reports about the Sudan outbreak, with its moderators adding valuable context. China’s mosquito-killing winters make a large yellow fever outbreak there unlikely, moderators said. But Sudan’s containment efforts are troubled. For example, vaccinated people cannot get cards proving they have had shots, but the cards are reported to be for sale at police checkpoints.

Australia’s now-endemic dengue fever, according to ProMED moderators, may have come from mosquitoes arriving in containers from East Timor.

Nintendo president describes Wii U sales as ‘not bad’

Nintendo’s (NTDOY) new Wii U gaming console came out of the gate strong and saw first-week sales reach 400,000 units in the U.S., however sales have since stalled and the system has been labeled a flop by some. While consumer interest in the company’s new console has slowed right out of the gate, Nintendo’s president recently said that he isn’t worried even though sales aren’t where he hoped they would be.

[More from BGR: Smooth sailing is over for Apple]

“At the end of the Christmas season, it wasn’t as though stores in the U.S. had no Wii U left in stock, as it was when Wii was first sold in that popular boom,” Nintendo President Satoru Iwata said in an interview with Reuters. “But sales are not bad, and I feel it’s selling steadily.”

[More from BGR: New ‘higher-end’ iPhone reportedly launching by June, low-end model could be coming as well]

The executive declined to give specific details on sales or forecasts, although he did say that Nintendo plans to focus on developing attractive software for its 3DS handheld to appeal to new users, and will seek new ways to increase Wii U sales in a changing market.

Nintendo previously announced that it hopes to sell 5.5 million Wii U devices by the end of March and more than 24 million Wii U games in the same timeframe.

Bonds, Clemens rejected; no one elected to BB Hall

NEW YORK (AP) — Steroid-tainted stars Barry Bonds, Roger Clemens and Sammy Sosa were denied entry to baseball's Hall of Fame, with voters failing to elect any candidates for only the second time in four decades.

In a vote that keeps the game's career home run leader and one of its greatest pitchers out of Cooperstown — at least for now — Bonds received just 36.2 percent of the vote and Clemens 37.6 in totals announced Wednesday by the Hall and the Baseball Writers' Association of America, both well short of the 75 percent necessary. Sosa, eighth on the career home run list, got 12.5 percent.

"Curt Schilling made a good point, everyone was guilty. Either you used PEDs, or you did nothing to stop their use," Hall of Famer Mike Schmidt said in an email to The Associated Press. "This generation got rich. Seems there was a price to pay."

Bonds, Clemens and Sosa were eligible for the first time and have up to 14 more years on the writers' ballot to gain baseball's highest honor.

"After what has been written and said over the last few years I'm not overly surprised," Clemens said in a statement he posted on Twitter.

Craig Biggio, 20th on the career list with 3,060 hits, topped the 37 candidates with 68.2 percent of the 569 ballots, 39 shy of election. Among other first-year eligibles, Mike Piazza received 57.8 percent and Schilling 38.8.

Jack Morris led holdovers with 67.7 percent. He will make his final ballot appearance next year, when fellow pitchers Greg Maddux and Tom Glavine along with slugger Frank Thomas are eligible for the first time.

Two-time NL MVP Dale Murphy received 18.6 percent in his 15th and final appearance.

"With 53 percent you can get to the White House, but you can't get to Cooperstown," BBWAA secretary-treasurer Jack O'Connell said. "It's the 75 percent that makes it difficult."

It was the eighth time the BBWAA failed to elect any players. There were four fewer votes than last year and five members submitted blank ballots.

"It's a tough period for evaluation, that's what this chalks up to," Hall President Jeff Idelson said. "Honestly, I think that any group you put this to would have the same issues. ... There's always going to be discussion and concern about players who didn't get in, but at the end of the day it's a process and again, a snapshot in time isn't one year, it's 15 with this exercise."

Bonds, baseball's only seven-time Most Valuable Player, hit 762 home runs, including a record 73 in 2001.

"It is unimaginable that the best player to ever play the game would not be a unanimous first-ballot selection," said Jeff Borris of the Beverly Hills Sports Council, Bonds' longtime agent.

Clemens, the only seven-time Cy Young Award winner, is third in career strikeouts and ninth in wins.

"To those who did take the time to look at the facts," Clemens said, "we very much appreciate it."

Since 1961, the only years the writers didn't elect a candidate were when Yogi Berra topped the 1971 vote by appearing on 67 percent of the ballots cast and when Phil Niekro headed the 1996 ballot at 68 percent. Both were chosen the following years when they achieved the 75 percent necessary for election.

The other BBWAA elections without a winner were in 1945, 1946, 1950, 1958 and 1960.

"Next year, I think you'll have a rather large class and this year, for whatever reasons, you had a couple of guys come really close," Commissioner Bud Selig said at the owners' meetings in Paradise Valley, Ariz. "This is not to be voted to make sure that somebody gets in every year. It's to be voted on to make sure that they're deserving. I respect the writers as well as the Hall itself. This idea that this somehow diminishes the Hall of baseball is just ridiculous in my opinion."

Players' union head Michael Weiner called the vote "unfortunate, if not sad."

"To ignore the historic accomplishments of Barry Bonds and Roger Clemens, for example, is hard to justify. Moreover, to penalize players exonerated in legal proceedings — and others never even implicated — is simply unfair. The Hall of Fame is supposed to be for the best players to have ever played the game. Several such players were denied access to the Hall today. Hopefully this will be rectified by future voting."

Three inductees were chosen last month by the 16-member panel considering individuals from the era before integration in 1947: Yankees owner Jacob Ruppert, umpire Hank O'Day and barehanded catcher Deacon White. They will be enshrined during a ceremony in Cooperstown on July 28, when the Hall also will honor Lou Gehrig and Rogers Hornsby among a dozen players who never received formal inductions because of restrictions during World War II.

Bonds has denied knowingly using performance-enhancing drugs and was convicted of one count of obstruction of justice for giving an evasive answer in 2003 to a grand jury investigating PEDs. Clemens was acquitted of perjury charges stemming from congressional testimony during which he denied using PEDs.

Sosa, who finished with 609 home runs, was among those who tested positive in MLB's 2003 anonymous survey, The New York Times reported in 2009. He told a congressional committee in 2005 that he never took illegal performance-enhancing drugs.

The BBWAA election rules say "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."

An Associated Press survey of 112 eligible voters conducted in late November after the ballot was announced indicated Bonds, Clemens and Sosa would fall well short of 50 percent. The big three drew even less support than that as the debate raged over who was Hall worthy.

Voters are writers who have been members of the BBWAA for 10 consecutive years at any point.

BBWAA president Susan Slusser of the San Francisco Chronicle said she didn't vote for Bonds, Clemens or Sosa.

"The evidence for steroid use is too strong," she said.

As for Biggio, "I'm surprised he didn't get in."

MLB.com's Hal Bodley, the former baseball columnist for USA Today, said Biggio and others paid the price for other players using PEDs.

"They got caught in the undertow of the steroids thing," he said.

Bodley said this BBWAA vote was a "loud and clear" message on the steroids issue. He said he couldn't envision himself voting for stars linked to drugs.

"We've a forgiving society, I know that," he said. "But I have too great a passion for the sport."

Mark McGwire, 10th on the career home run list, received 16.9 percent on his seventh try, down from 19.5 last year. He received 23.7 percent in 2010 — a vote before he admitted using steroids and human growth hormone.

Rafael Palmeiro, among just four players with 500 homers and 3,000 hits along with Hank Aaron, Willie Mays and Eddie Murray, received 8.8 percent in his third try, down from 12.6 percent last year. Palmeiro received a 10-day suspension in 2005 for a positive test for performance-enhancing drugs, claiming it was due to a vitamin vial given to him by teammate Miguel Tejada.

While there are exhibits about the Steroids Era at the Hall, the plaque room will remain without Bonds and Clemens, who join career hits leader Pete Rose on the outside looking in. There were four write-in votes for Rose, who never appeared on the ballot because of his lifetime ban that followed an investigation of his gambling while manager of the Cincinnati Reds.

Morris increased slightly from his 66.7 percent last year, when Barry Larkin was elected. Morris could become the player with the highest-percentage of the vote who is not in the Hall, a mark currently held by Gil Hodges at 63 percent in 1983.

Several players who fell just short in the BBWAA balloting later were elected by either the Veterans Committee or Old-Timers' Committee: Nellie Fox (74.7 percent on the 1985 BBWAA ballot), Jim Bunning (74.2 percent in 1988), Orlando Cepeda (73.6 percent in 1994) and Frank Chance (72.5 percent in 1945).

The ace of three World Series winners, Morris had 254 victories and was the winningest pitcher of the 1980s. His 3.90 ERA, however, is higher than that of any Hall of Famer.

Pap Test May Prove Useful at Detecting More Types of Cancer, Study Suggests

The Pap test, which has prevented countless deaths from cervical cancer, may eventually help to detect cancers of the uterus and ovaries as well, a new study suggests.

For the first time, researchers have found genetic material from uterine or ovarian cancers in Pap smears, meaning that it may become possible to detect three diseases with just one routine test.

But the research is early, years away from being used in medical practice, and there are caveats. The women studied were already known to have cancer, and while the Pap test found 100 percent of the uterine cancers, it detected only 41 percent of the ovarian cancers. And the approach has not yet been tried in women who appear healthy, to determine whether it can find early signs of uterine or ovarian cancer.

On the other hand, even a 41 percent detection rate would be better than the status quo in ovarian cancer, particularly if the detection extends to early stages. The disease is usually advanced by the time it is found, and survival is poor. About 22,280 new cases were expected in the United States in 2012, and 15,500 deaths. Improved tests are urgently needed.

Uterine cancer has a better prognosis, but still kills around 8,000 women a year in the United States.

These innovative applications of the Pap test are part of a new era in which advances in genetics are being applied to the detection of a wide variety of cancers or precancerous conditions. Scientists are learning to find minute bits of mutant DNA in tissue samples or bodily fluids that may signal the presence of hidden or incipient cancers. Ideally, the new techniques would find the abnormalities early enough to cure the disease or even prevent it entirely. But it is too soon to tell.

“Is this the harbinger of things to come? I would answer yes,” said Dr. Bert Vogelstein, director of the Ludwig Center for Cancer Genetics and Therapeutics at Johns Hopkins University, and a senior author of a report on the Pap test study published on Wednesday in the journal Science Translational Medicine. He said the genomes of more than 50 types of tumors had been sequenced, and researchers were trying to take advantage of the information.

Similar studies are under way or are being considered to look for mutant DNA in blood, stool, urine and sputum, both to detect cancer and also to monitor the response to treatment in people who already have the disease.

But researchers warn that such tests, used for screening, can be a double-edged sword if they give false positive results that send patients down a rabbit hole of invasive tests and needless treatments. Even a test that finds only real cancers may be unable to tell aggressive, dangerous ones apart from indolent ones that might never do any harm, leaving patients to decide whether to watch and wait or to go through surgery, chemotherapy and radiation with all the associated risks and side effects.

“Will they start recovering mutations that are not cancer-related?” asked Dr. Christopher P. Crum, a professor at Harvard Medical School who was not involved in the research.

But he also called the study a “great proof of principle,” and said, “Any whisper of hope to women who suffer from endometrial or ovarian cancer would be most welcome.”

DNA testing is already performed on samples from Pap tests, to look for the human papillomavirus, or HPV, which causes cervical cancer. Dr. Vogelstein and his team decided to try DNA testing for cancer. They theorized that cells or DNA shed from cancers of the ovaries and the uterine lining, or endometrium, might reach the cervix and turn up in Pap smears.

The team picked common mutations found in these cancers, and looked for them in tumor samples from 24 women with endometrial cancer and 22 with ovarian cancer. All the cancers had one or more of the common mutations.

Then, the researchers performed Pap tests on the same women, and looked for the same DNA mutations in the Pap specimens. They found the mutations in 100 percent of the women with endometrial cancer, but in only 9 of the 22 with ovarian cancer. The test identified two of the four ovarian cancers that had been diagnosed at an early stage.

Wall Street Modestly Higher

Wall Street stocks traded higher on Wednesday after Alcoa got the earnings season under way with better-than-expected revenue and an encouraging outlook for the year.

The Standard & Poor’s 500-stock index rose 0.2 percent in late trading, the Dow Jones industrial average added 0.4 percent and the Nasdaq composite index was up 0.4 percent. European shares closed moderately higher.

Alcoa said it expected global demand for aluminum would continue to grow in 2013, though the company kept a cautious tone as worries lingered over a looming budget confrontation in Washington. Shares of Alcoa, the largest aluminum producer in the United States, were almost unchanged.

Still, investors were wary about the outcome of the fourth-quarter earnings season. Profits were expected to beat the previous quarter’s lackluster results, but analysts’ estimates were down sharply from where they were in October. Earnings were expected to grow by 2.7 percent, according to Thomson Reuters data.

Equities have pulled back over the last two sessions from last week’s rally, which was spurred by a deal in Washington that averted automatic spending cuts and across-the-board tax increases.

“With the euphoria of the fiscal cliff deal wearing off, the market is looking for the next positive theme and the hope is that earnings season can fill that need,” said Andre Bakhos, director of market analytics at Lek Securities in New York. “With expectations muted, any semblance of decent numbers could provide a robust upside potential.”

Constellation Brands, whose labels include Robert Mondavi and Ravenswood wines, fell 0.4 percent after it reported higher profit.

Apollo Group slid more than 7 percent after it reported lower student sign-ups for the third straight quarter and cut its operating profit forecast for 2013.

Dish Network late Tuesday announced a bid for Clearwire that trumped Sprint Nextel’s $2.2 billion offer, setting the stage for a battle over the wireless service provider. Clearwire was up 7.8 percent, while Sprint lost 1.8 percent.

Seagate Technology, the maker of computer hard drives, rose 5.9 percent after it raised its second-quarter revenue forecast.

China Says It Will Overhaul Re-education System

BEIJING — China will start overhauling its draconian system of re-education through labor in the coming year, according to the state news media, signaling the incoming leadership’s determination to alter one of the government’s more widely despised cudgels for punishing petty criminals, religious dissidents, petitioners and other perceived social irritants.

The brief announcement on Monday, by the official Xinhua news agency, lacked details, but legal advocates said they were hopeful that the five-decade-old system for locking up offenders without trial would be significantly modified, if not abolished altogether.

“If true, this would be an important advance,” said Zhang Qianfan, a law professor at Peking University who has long pushed for the system’s demise. “It’s a tool that is widely abused.”

Established by Mao Zedong in the 1950s to swiftly neutralize political opponents, re-education through labor has evolved into a sprawling extralegal system of 350 camps where more than 100,000 people toil in prison factories and on farms for up to four years. Sentences are meted out by local public security officials, and defendants have no access to lawyers and little chance for appeal.

Since the 1980s, legal scholars and human rights advocates have been urging an end to the system and urging that the prosecution of minor offenses be shifted to criminal courts. The campaign has been re-energized in recent months by several cases, widely promoted in the news media, in which people were consigned to the camps for criticizing or simply annoying local party officials.

Among the more notable cases was that of Ren Jianyu, a college graduate turned village official in southwestern China who was sent to a work camp for “subversion” after investigators found in his closet a T-shirt that declared “Freedom or death.” In November, local officials, apparently cowed by a welter of condemnation in newspapers and on the Internet, cut short his two-year sentence.

A similar backlash also persuaded officials in Hunan Province last summer to free a woman, Tang Hui, who was given an 18-month sentence after she repeatedly protested that the seven men who had raped and forced her 11-year-old daughter into prostitution had been treated too leniently.

But any jubilation that the system might be on its way out was tempered by the manner in which the news emerged. Details of a conference held by top judicial and legal officials were reported online on Monday by a number of news media outlets — including word that the party would “stop using the system” within a year. Those accounts, however, were later deleted, leaving only the brief Xinhua account.

Chen Dongsheng, a bureau chief for the official Legal Daily who listened to a closed-circuit telecast of the meeting, told The Associated Press that Meng Jianzhu, chief of the Communist Party’s politics and law committee, had pledged to end the system, saying it had “played a useful role in the past, but conditions had now changed.”

But Mr. Chen’s microblog postings on the subject promptly disappeared, and he could not be reached for comment.

In its own report, Xinhua used the word “reform,” suggesting the changes to the system labor might be less than sweeping. Such changes could involve giving the system the legislative authority it currently lacks and subjecting decisions to some level of judicial review, although China’s party-controlled courts rarely rule in favor of defendants.

In a separate account of the same meeting, Xinhua included comments by Mr. Meng and Xi Jinping, the incoming president, but left out any mention of re-education through labor. Mr. Xi, who has promised to strengthen the nation’s legal system since his elevation to party secretary in November, reiterated his support for greater rule of law, saying the government should “improve empathy and public credibility of legal affairs work, striving to ensure that the public feels that justice is served in every law case.”

Rights advocates are pleased that the issue is on the leadership’s agenda but said that the devil would be in the details. Previous proposals for change, they noted, have included an 18-month cap on sentences, weekend furloughs for prisoners and access to lawyers for defendants. But such modifications alone, they said, would leave intact the bones of a system that violates international legal conventions as well as Chinese law.

“The risk is we’ll get re-education lite — a system that perpetuates the ability of police to deprive people of liberty for significant periods of time without trial or judicial oversight,” said Nicholas Bequelin, a senior researcher at Human Rights Watch. “My fear is that such a system would end up being harder to do away with.”
