Wall Street flat after rally, Caterpillar advances

NEW YORK (Reuters) - U.S. stocks were flat on Monday, with investors reluctant to make big bets following an extended equity rally, though strong data and results from Caterpillar kept a positive tone in markets.

The S&P 500 is coming off a streak of eight sessions of gains, the longest winning streak for the index in eight years. On Friday, it closed above 1,500 for the first time in more than five years.

Caterpillar Inc rose 1.8 percent to $97.24 after the Dow component reported adjusted fourth-quarter earnings that beat expectations, though revenue was slightly below forecasts. The heavy machinery maker also said it expects China's economy to improve, though not at the rates of 2010 and 2011.

The results continued the trend of major firms posting strong quarters, contributing to major averages rising for four straight weeks.

"You can't find more of a global bellwether than Cat, and people are pleased with the number, which suggests there could be less concern about slowing growth in China after this," said Wayne Kaufman, chief market analyst at John Thomas Financial in New York.

Thomson Reuters data through Friday showed that of the 147 S&P 500 companies that have reported earnings so far, 68 percent exceeded expectations. Since 1994, 62 percent of companies have topped expectations, while the average over the past four quarters stands at 65 percent.

The Dow Jones industrial average <.dji> was up 18.07 points, or 0.13 percent, at 13,914.05. The Standard & Poor's 500 Index <.spx> was down 0.07 points, or 0.00 percent, at 1,502.89. The Nasdaq Composite Index <.ixic> was up 7.25 points, or 0.23 percent, at 3,156.97.

The S&P 500 on Friday closed at its highest since December 10, 2007, and the Dow ended at its highest since October 31, 2007. Over the past four weeks, the S&P has jumped 7.2 percent, suggesting markets may be vulnerable to a pullback if news disappoints.

Durable goods jumped 4.6 percent in December, a pace that far outstripped expectations for a rise of 1.8 percent.

"We continue to have a parade of better-than-expected economic reports. All-in-all it's a good picture. I think there's a good chance we've reached a point of recognition where people don't think the economy will crater," Kaufman said.

In addition to earnings, equities have also risen on an agreement in Washington to extend the government's borrowing power. On Monday, Fitch Ratings said that agreement removed the near-term risk to the country's 'AAA' rating.

Previously, the agency said the lack of an agreement would prompt a review of the sovereign rating.

In company news, Keryx Biopharmaceuticals Inc said a late-stage trial of its experimental kidney disease drug met the main study goal of reducing phosphate levels in blood, sending shares up 43 percent to $4.91.

Bargain hunters may look to Apple Inc in the first session after the tech giant lost its coveted title as the largest U.S. company by market capitalization to Exxon Mobil Corp . Apple rose 0.7 percent to $443.06.

On Friday, Apple's market cap fell to $413 billion, down roughly $250 billion from its September peak. Apple's fall is about equal to the entire value of Google Inc .

"Apple is pretty attractive right now, so you may see an opportunity here," said Chris Bertelsen, who helps oversee $1.5 billion as chief investment officer of Global Financial Private Capital in Sarasota, Florida. "Those who think the stock is dead have made a big mistake."

Hackers Infect Government Websites with ‘Asteroids’ Game

Hackers angry over the suicide of Internet activist Aaron Swartz took over the website of the United States Sentencing Commission (USSC) twice over the weekend, finally infecting the homepage with a playable version of the classic arcade game “Asteroids.”

The hackers, claiming affiliation with the online movement Anonymous, also claimed to release a list of people in the federal Witness Security Program, also known as the Witness Protection Program, but that was quickly discovered to be a hoax.

Blood of the martyr

The attack began late Friday (Jan. 25), when the homepage of the USSC, which sets sentencing guidelines for federal courts, was defaced with a video regarding the prosecution of Swartz.

“We have seen the erosion of due process, the dilution of constitutional rights, the usurpation of the rightful authority of courts by the discretion of prosecutors,” said a voiceover on the video. “We have seen how the law is wielded less and less to uphold justice, and more and more to exercise control.”

Swartz, who hanged himself in his Brooklyn apartment earlier this month at the age of 26, was facing decades in federal prison for allegedly downloading millions of academic documents from an online archive to a laptop hidden on the campus of the Massachusetts Institute of Technology.

According to a report released last week, local authorities in Boston had not intended to seek any jail time for Swartz.

Federal prosecutors then took over the case, first indicting Swartz on four charges that carried a maximum penalty of 35 years in prison, then adding nine more charges in a second indictment that increased the possible prison time to 50 years.

Two weeks ago, Anonymous defaced the websites of MIT and the U.S. Department of Justice in Swartz’s memory.

[Are You Looking at This Website? You Might Be Breaking the Law]

Fire away

The USSC site was fixed Saturday (Jan. 26), but late Sunday the Twitter feed @OpLastResort issued a cryptic message.

“ussc.gov –> enter Konami code (with cursor keys) ↑↑↓↓←→←→ B A —> CAEK (repeat for NyanCat powers…)”

The Konami cheat code was a well-known method of gaining extra points on the Nintendo Entertainment System in the 1980s. On a computer, it would be up-up-down-down-left-right-left-right on the keyboard arrow keys, then “B,” “A” and “Enter.”

On Sunday evening, the USSC site appeared normal until the cheat code was entered, at which point a silhouette of the popular Internet meme “NyanCat” appeared.

The arrow keys maneuvered NyanCat and fired his thruster engine; pressing the spacebar fired his laser cannon, blowing away elements of the page until a background image of the Anonymous logo appeared.

On Monday morning (Jan. 28), the USSC’s site was unreachable, but the game had been ported to the website of the Eastern Michigan branch of the U.S. Probation Office at http://www.miep.uscourts.gov/.

Why haven't we learned from fires?

STORY HIGHLIGHTS

• Pyrotechnics, overcrowding, poor exits have contributed to tragic fires in recent years


• You would think the world would have learned from past incidents, John Barylick says


• Concertgoers have to be their own fire marshals, he says

Editor's note: John Barylick, author of "Killer Show," a book on the 2003 Station nightclub fire in Rhode Island, is an attorney who represented victims in wrongful death and personal injury cases arising from the fire.

(CNN) -- Sunday morning we awoke to breaking news of another tragic nightclub fire, this time in Brazil. At last report the death toll exceeded 230.

This tragedy is not without precedent. Next month will mark the 10th anniversary of a similar nightclub fire in Rhode Island. At this sad time, it's appropriate to reflect on what we've learned from club fires -- and what we haven't.

Rhode Island's Station nightclub fire of 2003, in which 100 concertgoers lost their lives, began when fireworks set off by Great White, an 80s heavy metal band, ignited flammable packing foam on the club's walls.

Deadly blazes: Nightclub tragedies in recent history

John Barylick

Panicked patrons stampeded toward the club's main exit, and a fatal pileup ensued. Contributing to the tragedy were illegal use of pyrotechnics, overcrowding and a wall covering that would have failed even the most rudimentary flammability tests.

Video images of the Station fire were broadcast worldwide: A concert begins; the crowd's mood changes from merry, to curious, to concerned, to horrified -- in less than a minute. You'd think the world would have learned from it. You would be wrong.

The following year, the Republica Cromanon nightclub in Argentina went up in flames, killing 194 people. The club was made to hold about 1,000 people, but it was estimated that more than 3,000 fans were packed inside the night of the fire, which began when fans began lighting flares that caught the roof on fire.

Echoes of the past: Rhode Island victims 'can't help but watch'

Then, in January 2009, at least 64 New Year's revelers lost their lives in a nightclub in Bangkok, Thailand, after fire ignited its ceiling. Many were crushed in a rush to get out of the club. In December of that same year, a fire in a Russian nightclub, ignited by pyrotechnics, killed 156 people. Overcrowding, poor exits, and indoor fireworks all played roles in these tragedies; yet no one bothered to learn from mistakes of the past.

While responsibility for concert disasters unquestionably lies with venue operators, performers and promoters, ultimately, we, as patrons of clubs and concerts, can enhance our own safety by taking a few simple steps. The National Fire Protection Association urges concertgoers to:

• Be observant. Is the concert venue rundown or well-maintained? Does the staff look well-trained?

• As you proceed to your seat, observe how long the process takes. Could you reverse it in a hurry? Do you pass through pinch points? Is furniture in the way?

• Once seated, take note of the nearest exit. (In an emergency, most people try to exit by the door they entered, which is usually not the closest, and is always overcrowded.) Then, share the location of that nearest exit with your entire party. Agree that at the first sign of trouble, you will all proceed to it without delay.

• Once the show begins, remain vigilant. If you think there's a problem, LEAVE IMMEDIATELY. Do not stay to "get your money's worth" despite concerns about safety. Do not remain to locate that jacket or bag you placed somewhere. No concert is worth your life. Better to read about an incident the next day than be counted as one of its statistics.

Read more: How to protect yourself in a crowd

To be sure, all fire codes must be vigorously enforced, and club and concert hall operators must be held to the highest standards. A first step is banning indoor pyrotechnics in all but the largest, stadium-type venues.

But, ultimately, we are our own best "fire marshals" when it comes to avoiding, and escaping, dangerous situations. We can still enjoy shows. But it is up to us to look out for our own safety.

In coming days, Rhode Islanders will follow the unfolding news from Brazil with a sense of queasy deja vu -- the rising body counts, the victim identification process, the grieving families, and the assigning (and dodging) of blame. If only they had learned from our tragedy.

The opinions expressed in this commentary are solely those of John Barylick.

2 killed in West Rogers Park in possible carbon monoxide leak

Police are investigating whether a carbon monoxide leak led to the deaths of two people in West Rogers Park.

The family of a 77-year-old woman and her 18-year-old granddaughter are in shock after the two died Sunday in their West Rogers Park apartment building as authorities investigate whether a carbon monoxide leak is to blame.

Rasheeda Akhter was pronounced dead at 11:14 a.m., according to the Cook County medical examiner's office. Her granddaughter, Zanib Ahmed, died at 9 p.m., according to the medical examiner's office.

"Our family is going through a tough time, they were very good people," said a relative who did not give his name. "We were up all night."

Paramedics were first called about 10:30 a.m. Sunday to the building in the 2500 block of West North Shore Avenue to transport one woman to the hospital, Chicago Fire Department spokeswoman Meg Ahlheim said.

The woman was taken in cardiac arrest to Swedish Covenant Hospital, Ahlheim said.

Fire officials at the scene called for a second ambulance, and another woman was taken to Swedish Covenant as well.

Both women died at the hospital.

Back at the building, fire officials checked the carbon monoxide levels but found no indication of a leak, Ahlheim said.

Paramedics were called back to the scene, however, about 3:45 p.m. for another woman found unresponsive. She was taken to St. Francis Hospital in Evanston in critical condition, Ahlheim said.

Officials checked carbon monoxide levels again, and while the meter readings in residential units did not indicate a leak, officials found a positive reading for a low level of carbon monoxide near a boiler in the basement, Ahlheim said.

Police suspect the deaths were caused by accidental carbon monoxide poisoning, but no official determination will be made until autopsy results are reported, Police News Affairs Officer Amina Greer said.

A spokeswoman for Peoples Gas, Jennifer Block, said representatives from the company were called to the building to assist police and fire officials. She referred further questions to the police and fire departments.

Violence flares in Egypt after emergency law imposed

CAIRO (Reuters) - A man was shot dead on Monday in a fifth day of violence in Egypt that has killed 50 people and prompted the Islamist president to declare a state of emergency in an attempt to end a wave of unrest sweeping the Arab world's biggest nation.

Emergency rule announced by President Mohamed Mursi on Sunday covers the cities of Port Said, Ismailia and Suez. The army has already been deployed in two of those cities and cabinet approved a measure to let soldiers arrest civilians.

A cabinet source told Reuters any trials would be before civilian courts, but the step is likely to anger protesters who accuse Mursi of using high-handed security tactics of the kind they fought against to oust President Hosni Mubarak.

Egypt's politics have become deeply polarized since those heady days two years ago, when protesters were making most of the running in the Arab Spring revolutions that sent shockwaves through the region and Islamists and liberals lined up together.

Although Islamists have won parliamentary and presidential elections, the disparate opposition has since united against Mursi. Late last year he moved to expand his powers and push a constitution with Islamist leanings through a referendum, punctuated by violent street protests.

Mursi's call for a national dialogue meeting on Monday to help end the crisis was spurned by his main opponents.

They accuse Mursi of hijacking the revolution, listening only to his Islamist allies and breaking a promise to be a president for all Egyptians. Islamists say their rivals want to overthrow by undemocratic means Egypt's first freely elected leader.

Anti-Mursi protesters were out on the streets again in Cairo and elsewhere on Monday, the second anniversary of one of the bloodiest days in the revolution that erupted on January 25, 2011, and ended Mubarak's iron rule 18 days later.

CONCERNS

Hundreds of demonstrators in Port Said, Ismailia and Suez, cities which all lie on the economically vital Suez Canal, had turned out against Mursi's decision on Sunday within moments of him speaking. Activists there pledged to defy a curfew that starts at 9 p.m. (1700 GMT).

Instability in Egypt has raised concerns in Western capitals, where officials worry about the direction of a key regional player that has a peace deal with Israel.

The political unrest has been exacerbated by street violence linked to death penalties imposed on soccer supporters convicted of involvement in stadium rioting a year ago.

In Cairo on Monday, police fired volleys of teargas at stone-throwing protesters near Tahrir Square, cauldron of the anti-Mubarak uprising. A 46-year-old bystander was killed by a gunshot, a security source said. It was not clear who opened fire.

"We want to bring down the regime and end the state that is run by the Muslim Brotherhood," said Ibrahim Eissa, a 26-year-old cook, protecting his face from teargas wafting towards him.

Propelled to the presidency in a June election by the Muslim Brotherhood, Mursi has lurched through a series of political crises and violent demonstrations, complicating his task of shoring up the economy and of preparing for a parliamentary election to cement the new democracy in a few months.

"The protection of the nation is the responsibility of everyone. We will confront any threat to its security with force and firmness within the remit of the law," Mursi said, angering many of his opponents when he wagged his finger at the camera.

The president offered condolences to families of victims of violence and also called a dialogue meeting on Monday at 6 p.m. (11 a.m. ET) between Islamist allies and their liberal, leftist and other opponents to discuss the crisis.

The main opposition National Salvation Front coalition rejected the offer as "cosmetic and not substantive" and set several conditions that have not been met in the past, such as forming a national salvation government. They also demanded that Mursi announce his responsibility for the bloodshed.

SECURITY MEASURES

"We will send a message to the Egyptian people and the president of the republic about what we think are the essentials for dialogue. If he agrees to them, we are ready for dialogue," opposition politician Mohamed ElBaradei told a news conference.

The opposition Front has distanced itself from the latest flare-ups but said Mursi should have acted far sooner to impose security measures that would have ended the violence.

"Of course we feel the president is missing the real problem on the ground, which is his own policies," Front spokesman Khaled Dawoud said after Mursi made his declaration.

Other activists said Mursi's measures to try to impose control on the turbulent streets could backfire.

"Martial law, state of emergency and army arrests of civilians are not a solution to the crisis," Ahmed Maher of the April 6 movement that helped galvanize the 2011 uprising said. "All this will do is further provoke the youth. The solution has to be a political one that addresses the roots of the problem."

Thousands of mourners joined funerals in Port Said for the latest victims in the Mediterranean port city. Seven people were killed there on Sunday when residents joined marches to bury 33 others who had been killed a day earlier, most by gunshot wounds in a city where arms are rife.

Protests erupted there on Saturday after a court sentenced to death several people from the city for their role in deadly soccer violence last year, a verdict residents saw as unfair. The anger swiftly turned against Mursi and his government.

Rights activists said Mursi's declaration was a backward step for Egypt, which was under emergency law for Mubarak's entire 30-year rule. His police used the sweeping arrest provisions to muzzle dissent and round up opponents, including members of the Brotherhood and even Mursi himself.

Heba Morayef of Human Rights Watch in Cairo said the police, still hated by many Egyptians for their heavy-handed tactics under Mubarak, would once again have the right to arrest people "purely because they look suspicious", undermining efforts to create a more efficient and respected police force.

"It is a classic knee-jerk reaction to think the emergency law will help bring security," she said. "It gives so much discretion to the Ministry of Interior that it ends up causing more abuse, which in turn causes more anger."

Wall Street Week Ahead: Bears hibernate as stocks near record highs

NEW YORK (Reuters) - Stocks have been on a tear in January, moving major indexes within striking distance of all-time highs. The bearish case is a difficult one to make right now.

Earnings have exceeded expectations, the housing and labor markets have strengthened, lawmakers in Washington no longer seem to be the roadblock that they were for most of 2012, and money has returned to stock funds again.

The Standard & Poor's 500 Index <.spx> has gained 5.4 percent this year and closed above 1,500 - climbing to the spot where Wall Street strategists expected it to be by mid-year. The Dow Jones industrial average <.dji> is 2.2 percent away from all-time highs reached in October 2007. The Dow ended Friday's session at 13,895.98, its highest close since October 31, 2007.

The S&P has risen for four straight weeks and eight consecutive sessions, the longest streak of days since 2004. On Friday, the benchmark S&P 500 ended at 1,502.96 - its first close above 1,500 in more than five years.

"Once we break above a resistance level at 1,510, we dramatically increase the probability that we break the highs of 2007," said Walter Zimmermann, technical analyst at United-ICAP, in Jersey City, New Jersey. "That may be the start of a rise that could take equities near 1,800 within the next few years."

The most recent Reuters poll of Wall Street strategists estimated the benchmark index would rise to 1,550 by year-end, a target that is 3.1 percent away from current levels. That would put the S&P 500 a stone's throw from the index's all-time intraday high of 1,576.09 reached on October 11, 2007.

The new year has brought a sharp increase in flows into U.S. equity mutual funds, and that has helped stocks rack up four straight weeks of gains, with strength in big- and small-caps alike.

That's not to say there aren't concerns. Economic growth has been steady, but not as strong as many had hoped. The household unemployment rate remains high at 7.8 percent. And more than 75 percent of the stocks in the S&P 500 are above their 26-week highs, suggesting the buying has come too far, too fast.

MUTUAL FUND INVESTORS COME BACK

All 10 S&P 500 industry sectors are higher in 2013, in part because of new money flowing into equity funds. Investors in U.S.-based funds committed $3.66 billion to stock mutual funds in the latest week, the third straight week of big gains for the funds, data from Thomson Reuters' Lipper service showed on Thursday.

Energy shares <.5sp10> lead the way with a gain of 6.6 percent, followed by industrials <.5sp20>, up 6.3 percent. Telecom <.5sp50>, a defensive play that underperforms in periods of growth, is the weakest sector - up 0.1 percent for the year.

More than 350 stocks hit new highs on Friday alone on the New York Stock Exchange. The Dow Jones Transportation Average <.djt> recently climbed to an all-time high, with stocks in this sector and other economic bellwethers posting strong gains almost daily.

"If you peel back the onion a little bit, you start to look at companies like Precision Castparts , Honeywell , 3M Co and Illinois Tool Works - these are big, broad-based industrial companies in the U.S. and they are all hitting new highs, and doing very well. That is the real story," said Mike Binger, portfolio manager at Gradient Investments, in Shoreview, Minnesota.

The gains have run across asset sizes as well. The S&P small-cap index <.spcy> has jumped 6.7 percent and the S&P mid-cap index <.mid> has shot up 7.5 percent so far this year.

Exchange-traded funds have seen year-to-date inflows of $15.6 billion, with fairly even flows across the small-, mid- and large-cap categories, according to Nicholas Colas, chief market strategist at the ConvergEx Group, in New York.

"Investors aren't really differentiating among asset sizes. They just want broad equity exposure," Colas said.

The market has shown resilience to weak news. On Thursday, the S&P 500 held steady despite a 12 percent slide in shares of Apple after the iPhone and iPad maker's results. The tech giant is heavily weighted in both the S&P 500 and Nasdaq 100 <.ndx> and in the past, its drop has suffocated stocks' broader gains.

JOBS DATA MAY TEST THE RALLY

In the last few days, the ratio of stocks hitting new highs versus those hitting new lows on a daily basis has started to diminish - a potential sign that the rally is narrowing to fewer names - and could be running out of gas.

Investors have also cited sentiment surveys that indicate high levels of bullishness among newsletter writers, a contrarian indicator, and momentum indicators are starting to also suggest the rally has perhaps come too far.

The market's resilience could be tested next week with Friday's release of the January non-farm payrolls report. About 155,000 jobs are seen being added in the month and the unemployment rate is expected to hold steady at 7.8 percent.

"Staying over 1,500 sends up a flag of profit taking," said Jerry Harris, president of asset management at Sterne Agee, in Birmingham, Alabama. "Since recent jobless claims have made us optimistic on payrolls, if that doesn't come through, it will be a real risk to the rally."

A number of marquee names will report earnings next week, including bellwether companies such as Caterpillar Inc , Amazon.com Inc , Ford Motor Co and Pfizer Inc .

On a historic basis, valuations remain relatively low - the S&P 500's current price-to-earnings ratio sits at 15.66, which is just a tad above the historic level of 15.

Worries about the U.S. stock market's recent strength do not mean the market is in a bubble. Investors clearly don't feel that way at the moment.

"We're seeing more interest in equities overall, and a lot of flows from bonds into stocks," said Paul Zemsky, who helps oversee $445 billion as the New York-based head of asset allocation at ING Investment Management. "We've been increasing our exposure to risky assets."

For the week, the Dow climbed 1.8 percent, the S&P 500 rose 1.1 percent and the Nasdaq advanced 0.5 percent.

Djokovic beats Murray for 3rd straight Aust. title

MELBOURNE, Australia (AP) — Novak Djokovic became the first man in the Open era to win three consecutive Australian titles when he beat Andy Murray 6-7 (2), 7-6 (3), 6-3, 6-2 in Sunday's final.

Little wonder he loves Rod Laver Arena.

"It's definitely my favorite Grand Slam," he said. "It's an incredible feeling winning this trophy once more. I love this court."

Djokovic has won four of his six major titles at Melbourne Park, where he is now unbeaten in 21 matches.

Nine other men had won back-to-back titles in Australia over 45 years, but none were able to claim three in a row.

Only two other men, American Jack Crawford (1931-33) and Australian Roy Emerson (1963-67), have won three or more consecutive Australian championships.

Born a week apart in May 1987 and friends since their junior playing days, Djokovic and Murray played like they knew each other's game very well in a rematch of last year's U.S. Open final. There were no service breaks until the eighth game of the third set, when Djokovic finally broke through and then held at love to lead by two sets to one.

Djokovic earned two more service breaks in the fourth set, including one to take a 4-1 lead when U.S. Open champion Murray double-faulted on break point.

"It's been an incredible match as we could have expected," Djokovic said. "When we play each other, it's always, we push each other to the limit and I think those two sets went over two hours, 15 minutes, physically I was just trying to hang in there. Play my game and focus on every point."

The 25-year-old Serb didn't rip his shirt off this time, as he did to celebrate his epic 5-hour, 53-minute win over Rafael Nadal in last year's final. He just did a little dance, looked up to the sky and then applauded the crowd after the 3-hour, 40-minute match.

Murray's win over Djokovic in the U.S. Open final last year ended a 76-year drought for British men at the majors, but he still is yet to make a breakthrough in Australia after losing a third final here in the last four years.

Djokovic's win went against the odds of recent finals at Melbourne Park. In four of the past five years, the player who won the second of the semifinals has finished on top in the championship match. But this year, Djokovic played his semifinal on Thursday — an easy 89-minute minute win over No. 4-seeded David Ferrer. Murray needed five energy sapping sets to beat 17-time major winner Roger Federer on Friday night.

"You don't wake up the next day and feel perfect, obviously," Murray said of the Federer match. "It's the longest match I played in six months probably. It obviously wasn't an issue today. I started the match well. I thought I moved pretty good throughout."

The win consolidated Djokovic's position as the No. 1-ranked player in the world, while Federer and Murray will be second and third when the ATP rankings are released Monday.

Their last two matches in Grand Slams — Murray's five-set win at last year's U.S. Open and Djokovic's victory here last year in five in the semifinals — had a total of 35 service breaks.

It was a vastly different, more tactical battle on Sunday, with the first two tight sets decided in tiebreakers.

"All our matches in last three years have been decided in a very few points, so it's really hard to say if I've done anything different," Djokovic said. "I tried to be more aggressive. So I went for my shots, especially in the third and fourth; came to the net quite often. I was quite successful in that percentage, so it worked well for me."

Murray, who called for a trainer to retape blisters on his right foot at the end of the second set, was visibly annoyed by noise from the crowd during his service games in the third set, stopping his service motion twice until the crowd quieted down. After dropping the third set, he complained about the noise to chair umpire John Blom.

"It's just a bit sore when you're running around," Murray said. "It's not like pulling a calf muscle or something. It just hurts when you run."

Djokovic came from 0-40 down in the second game of the second set to hold his serve, something he called "definitely one of the turning points."

"He missed an easy backhand and I think mentally I just relaxed after that," Djokovic said. "I just felt I'm starting to get into the rhythm that I wanted to. I was little more aggressive and started to dictate the play."

Although Djokovic went into the match with a 10-7 lead in head-to-heads, Murray had beaten Djokovic five out of eight times in tiebreakers, and that improved to six of nine after four unforced errors by Djokovic to end the first set.

Djokovic pegged back that edge in the second set, when Murray also didn't help his cause by double-faulting to give Djokovic a 3-2 lead, and the Serbian player didn't trail again in the tiebreaker.

On the double-fault, Murray had to stop as he was about to serve to pick up a feather that had fallen on the court.

"I could have served, it just caught my eye before I served ... I thought it was a good idea to move it," he said.

"Maybe it wasn't because I obviously double faulted. At this level it can come down to just a few points here or there. My probably biggest chance was at the beginning of the second set; (I) didn't quite get it. When Novak had his chance at the end of the third, he got his."

Djokovic will have little time to savor the win — he's playing Davis Cup for Serbia next weekend against Belgium.

"It's going to be a lot of fun ... to see how I can adjust to clay court in indoor conditions, playing away Davis Cup, which is always tricky," he said.

Andre Agassi was among those in the capacity crowd — the four-time Australian champion's first trip Down Under in nearly 10 years — and he later presented the trophy to Djokovic.

Victoria Azarenka, who won Saturday's women's singles final over Li Na, was also there with her boyfriend rapper Redfoo. Actor Kevin Spacey met in the dressing room with both players ahead of the match and later tweeted a photo of himself with them.

In the earlier mixed doubles final Sunday, wild-card entrants Jarmila Gajdosova and Matthew Ebden of Australia beat the Czech pair of Lucie Hradecka and Frantisek Cermak 6-3, 7-5.

Women in infantry: Tough challenge?

Hospital Corpsman Shannon Crowley packs for a mission as Lance Cpl.. Kristi Baker sits on her bed in 2010 in Afghanistan.

STORY HIGHLIGHTS

• Maren Leed: Ban on women in combat has hurt operations, women's promotion


• Leed: Integrating women into the physically demanding infantry presents challenges


• Women are already in combat; she says, the "front line" and "rear line" no longer exist


• Leed: Research into women in infantry might show that some limits might be appropriate

Editor's note: Maren Leed is senior adviser, Harold Brown Chair in defense policy studies at the Center for Strategic and International Studies. From 2011 to 2012, she served as senior adviser to the chief of staff of the U.S. Army. Follow the Center for Strategic and International Studies on Twitter.

(CNN) -- In the coming years, lifting the ban on women in combat, announced Thursday by Defense Secretary Leon Panetta, might prove particularly challenging in the most iconic of military occupations -- the infantry, among the most physically demanding and tradition-bound branches of the Marines and the Army.

Determining the best path forward to integrate women into this elite group will require hard-nosed honesty, careful management and compelling leadership.

For the 65 years that women have enjoyed a permanent place in the United States military, they have been subject to restrictions. One rationale is the notion embedded in our culture that women should be shielded from great physical risks. Another is a recognition of the physical superiority of the average male over the average female. A third is the fear that unit cohesion, critical to military performance, would suffer with the introduction of women.

These three concerns apply to varying degrees in the infantry. But the last 11 years of war have clearly demonstrated that warfare is no longer waged in a linear fashion, and that the concept of "front line" no longer applies.

Opinion: A more equal military? Bring back draft

Historically, logistics operations were conducted "in the rear," where risks were comparatively low. This has changed: In 2006 in Iraq, for example, one in every five truck convoys was attacked. Although infantry clearly remains one of the most dangerous military occupations, the proliferation of homemade bombs and other low-cost, lethal weaponry and tactics have heightened the risk of almost every occupation. War is more uniformly dangerous.

That said, physical differences between the sexes remains a thorny issue. Determining gender-neutral physical standards for an integrated infantry will be one of the most difficult tasks ahead.

Infantry soldiers and Marines are the primary forces for operations on foot. They not only travel long distances, but also frequently carry loads in excess of 50 pounds. Both the short- and long-term health effects of such demands can be significant.

The Defense Department has consistently pursued solutions to lighten the load, from exoskeletons to unmanned vehicles that would serve as "pack mules," to the elusive quest for higher power, lower weight batteries.

The success of these efforts will benefit both men and women. But until that happens, research into the effects these physical demands have on women is necessary before determining the degree to which they can, and should, be part of the full range of infantry.

Whether men serving in the infantry will accept women as peers is another open question.

Those who oppose women in the infantry argue that they would change group dynamics, disrupt bonding and ultimately harm unit cohesion. In the past, these fears have been brought up regarding the participation of minorities and homosexuals, too. But data show these negative predictions don't come true. Instead, successful integration has happened with strong leadership, and, critically, a process that is broadly perceived to be fair.

Opinion: Women in combat a dangerous experiment

Even if the arguments underpinning the ban on women in combat have weakened, is there sufficient justification for change? The Joint Chiefs apparently believe so, as they have unanimously recommended the ban be lifted.

Each of the services already has been taking steps along these lines. This is in part driven by the evolution of the battlefield. When today's senior leaders were serving time in Iraq and Afghanistan, they realized that the restrictions on women sometimes also restricted their missions.

They implemented work-arounds and sought exceptions to policy. But they came home with firsthand experience of the mismatch between modern warfare and the policies limiting women's role. Women are in combat, and senior military leaders believe that future success demands they must remain available to be so, in even greater numbers.

From the institutional viewpoint, there are also concerns that the traditional limitations fail to make the best use of women in the service. Combat experience weighs heavily in promotion decisions, and restrictions have precluded women from gaining experiences equal to those of male counterparts.

Women are also excluded from many of the occupations disproportionately represented in senior leadership, and that automatically limits the number of women who can advance to the highest levels. At the same time, the pool of Americans eligible for military service is shrinking, and competition for high-quality recruits is intensifying. So it's imperative that the military fully leverage the talent of the men and women it has and that it seeks to attract.

By the numbers: Women in the U.S. military

The arguments in favor of lifting the ban on women in combat outweigh those against it. Despite Defense Secretary Leon Panetta's announcement on Thursday, the military services maintain the prerogative to preclude women from serving in certain positions or occupations.

Infantry, or at least some specialties within that branch, could well be a case in which restrictions are warranted. But military leaders have time to evaluate this proposition, and to set the conditions to make any change stick. The path ahead may not be smooth, but it is necessary.

Fire kills at least 245 in Brazil nightclub

A fire swept through a crowded nightclub in southern Brazil early Sunday, killing at least 245 people and leaving at least 200 injured, police and firefighters said. (Jan. 27)

PORTO ALEGRE, Brazil—

A fire in a nightclub killed at least 245 people in southern Brazil on Sunday when a band's pyrotechnics show set the building ablaze and fleeing patrons were unable to find the emergency exits in the ensuing panic, officials said.

The blaze in the southern city of Santa Maria was started when a band member or someone from its production team ignited a flare, which then set fire to the ceiling, said Luiza Sousa, a civil police official. The fire spread "in seconds," she said.

An estimated 500 people were in the Boate Kiss nightclub when the fire broke out early on Sunday, and many were unable to find the exits as dark smoke quickly filled the room. At least one exit was locked, trapping hundreds inside to die, many from asphyxiation as they inhaled smoke, police said.

"When I looked around, all I saw were dead bodies all around, lying on the floor. It was macabre," survivor Taynne Vendrusculo told GloboNews TV. "It all happened so fast. Both the panic and the fire spread rapidly, in seconds."

Television footage showed people sobbing outside the club, while shirtless firefighters used sledge hammers and axes to knock down an exterior wall to open up an exit.

By noon (1400 GMT), the death toll had risen to 245 and 48 people were being treated in local hospitals, said Major Cleberson Bastianello, head of the military police unit leading the rescue efforts. He said all of the bodies of the victims had been removed from the nightclub.

President Dilma Rousseff, who started her political career in the same state where the fire happened, cut short a visit to Chile to return to Brazil to visit the scene. Before departing, Rousseff gave a televised statement in which she broke out in tears as she pledged government help for the victims and their families.

"We are trying to mobilize all possible resources to help in the rescue efforts," she said. "All I can say at the moment is that my feelings are of deep sorrow."

The disaster recalls other incidents including a 2003 fire at a nightclub in West Warwick, Rhode Island, that killed 100, and a Buenos Aires nightclub blaze in 2004 that killed nearly 200. In both incidents, a band or members of the audience ignited fires that set the establishment ablaze.

Brazil's safety standards and emergency response capabilities are under particular scrutiny as it prepares to host the 2014 World Cup soccer tournament and the 2016 Olympics.

The Boate Kiss nightclub was a popular venue in Santa Maria, a university town of more than 275,000 people. The massive nightclub sometimes attracts up to 2,000 people on a given night, according to reviews on the Internet.

One of the club's owners had already surrendered to police in Santa Maria for questioning, GloboNews reported.

Rio Grande do Sul state Health Secretary Ciro Simoni said emergency medical supplies from all over the state were being sent to the scene.

Santa Maria is some 186 miles west of the state capital of Porto Alegre. "A sad Sunday!" tweeted Rio Grande do Sul Governor Tarso Genro. He said "all possible measures" were being taken in response.
