In Last Sunday Address as Pope, Benedict Says He Will Continue to Serve

Andrew Medichini/Associated Press

Pope Benedict XVI delivered his final Sunday address from the window of his apartment overlooking St. Peter's Square.

VATICAN CITY — In his last Sunday blessing before he retires, Pope Benedict XVI reassured Catholics that he was not abandoning them but would continue to serve the church even in his retirement.

Romans, pilgrims and curious tourists filled St. Peter’s Square on Sunday for Benedict’s second-to-last public appearance before he steps down on Thursday, the first pope in six centuries to do so willingly.

Reading from prepared remarks as he stood at the window of the Apostolic Palace, Benedict that said he was being called by God “to climb up on the mountain” and to dedicate himself more to “prayer and meditation.”

“This doesn’t mean abandoning the church,” the pope added, to the applause of the crowd. “On the contrary, if God asks me, this is because I can continue to serve” the church “with the same dedication and the same love which I have tried to do so until now, but in a way more suitable to my age and to my strength.”

Cardinals from around the world have begun gathering in Rome to greet Benedict before he retires at 8 p.m. on Thursday. At that point, the cardinals will meet to discuss when to begin the conclave to elect his successor.

One member of the crowd in St. Peter’s Square on Sunday, Jan Cartwright, 61, said she had traveled to Rome from Wales. “We’ve come for the rugby, but we’re Catholic, and it is history, isn’t it,” she said.

Ms. Cartwright said she was surprised that the pope had decided to resign. “We have the queen,” she said. “No one in the royal family would step down, they just go on until they die, really.” But she said she admired Benedict’s decision. “I think it’s a brave thing to do,” she said. “He’s an old man.”

Maria Concetta Campanella from Rome was also in the crowd. “It’s a historic moment,” she said. “It teaches us humility. He teaches us that we can’t sit in our chairs forever, that when the time is right, we have to leave the chair.”

Vito Ugo, an Augustinian monk holding a Brazilian flag, was taking pictures with two of his fellow monks, all dressed in long black robes. “We feel great emotion to be here,” he said.

Asked whether he hoped the cardinals would elect a South American pope in the conclave, Brother Ugo smiled. “It’s what God wants,” he said humbly.

Many States Say Cuts Would Burden Fragile Recovery

States are increasingly alarmed that they could become collateral damage in Washington’s latest fiscal battle, fearing that the impasse could saddle them with across-the-board spending cuts that threaten to slow their fragile recoveries or thrust them back into recession.

Some states, like Maryland and Virginia, are vulnerable because their economies are heavily dependent on federal workers, federal contracts and military spending, which will face steep reductions if Congress allows the automatic cuts, known as sequestration, to begin next Friday. Others, including Illinois and South Dakota, are at risk because of their reliance on the types of federal grants that are scheduled to be cut. And many states simply fear that a heavy dose of federal austerity could weaken their economies, costing them jobs and much-needed tax revenue.

So as state officials begin to draw up their budgets for next year, some say that the biggest risk they see is not the weak housing market or the troubled European economy but the federal government. While the threat of big federal cuts to states has become something of a semiannual occurrence in recent years, state officials said in interviews that they fear that this time the federal government might not be crying wolf — and their hopes are dimming that a deal will be struck in Washington in time to avert the cuts.

The impact would be widespread as the cuts ripple across the nation over the next year.

Texas expects to see its education aid slashed hundreds of millions of dollars, which could force local school districts to fire teachers, if the cuts are not averted. Michigan officials say they are in no position to replace the lost federal dollars with state dollars, but worry about cuts to federal programs like the one that helps people heat their homes. Maryland is bracing not only for a blow to its economy, which depends on federal workers and contractors and the many private businesses that support them, but also for cuts in federal aid for schools, Head Start programs, a nutrition program for pregnant women, mothers and children, and job training programs, among others.

Gov. Bob McDonnell of Virginia, a Republican, warned in a letter to President Obama on Monday that the automatic spending cuts would have a “potentially devastating impact” and could force Virginia and other states into a recession, noting that the planned cuts to military spending would be especially damaging to areas like Hampton Roads that have a big Navy presence. And he noted that the whole idea of the proposed cuts was that they were supposed to be so unpalatable that they would force officials in Washington to come up with a compromise.

“As we all know, the defense, and other, cuts in the sequester were designed to be a hammer, not a real policy,” Mr. McDonnell wrote. “Unfortunately, inaction by you and Congress now leaves states and localities to adjust to the looming threat of this haphazard idea.”

The looming cuts come just as many states feel they are turning the corner after the prolonged slump caused by the recession. Gov. Martin O’Malley of Maryland, a Democrat, said he was moving to increase the state’s cash reserves and rainy day funds as a hedge against federal cuts.

“I’d rather be spending those dollars on things that improve our business climate, that accelerate our recovery, that get more people back to work, or on needed infrastructure — transportation, roads, bridges and the like,” he said, adding that Maryland has eliminated 5,600 positions in recent years and that its government was smaller, on a per capita basis, than it had been in four decades. “But I can’t do that. I can’t responsibly do that as long as I have this hara-kiri Congress threatening to drive a long knife through our recovery.”

Federal spending on salaries, wages and procurement makes up close to 20 percent of the economies of Maryland and Virginia, according to an analysis by the Pew Center on the States.

But states are in a delicate position. While they fear the impact of the automatic cuts, they also fear that any deal to avert them might be even worse for their bottom lines. That is because many of the planned cuts would go to military spending and not just domestic programs, and some of the most important federal programs for states, including Medicaid and federal highway funds, would be exempt from the cuts.

States will see a reduction of $5.8 billion this year in the federal grant programs subject to the automatic cuts, according to an analysis by Federal Funds Information for States, a group created by the National Governors Association and the National Conference of State Legislatures that tracks the impact of federal actions on states. California, New York and Texas stand to lose the most money from the automatic cuts, and Puerto Rico, which is already facing serious fiscal distress, is threatened with the loss of more than $126 million in federal grant money, the analysis found.

Even with the automatic cuts, the analysis found, states are still expected to get more federal aid over all this year than they did last year, because of growth in some of the biggest programs that are exempt from the cuts, including Medicaid.

But the cuts still pose a real risk to states, officials said. State budget officials from around the country held a conference call last week to discuss the threatened cuts. “In almost every case the folks at the state level, the budget offices, are pretty much telling the agencies and departments that they’re not going to backfill — they’re not going to make up for the budget cuts,” said Scott D. Pattison, the executive director of the National Association of State Budget Officers, which arranged the call. “They don’t have enough state funds to make up for federal cuts.”

The cuts would not hit all states equally, the Pew Center on the States found. While the federal grants subject to the cuts make up more than 10 percent of South Dakota’s revenue, it found, they make up less than 5 percent of Delaware’s revenue.

Many state officials find themselves frustrated year after year by the uncertainty of what they can expect from Washington, which provides states with roughly a third of their revenues. There were threats of cuts when Congress balked at raising the debt limit in 2011, when a so-called super-committee tried and failed to reach a budget deal, and late last year when the nation faced the “fiscal cliff.”

John E. Nixon, the director of Michigan’s budget office, said that all the uncertainty made the state’s planning more difficult. “If it’s going to happen,” he said, “at some point we need to rip off the Band-Aid.”

Drone Pilots Found to Get Stress Disorders Much as Those in Combat Do

U.S. Air Force/Master Sgt. Steve Horton

Capt. Richard Koll, left, and Airman First Class Mike Eulo monitored a drone aircraft after launching it in Iraq.

The study affirms a growing body of research finding health hazards even for those piloting machines from bases far from actual combat zones.

“Though it might be thousands of miles from the battlefield, this work still involves tough stressors and has tough consequences for those crews,” said Peter W. Singer, a scholar at the Brookings Institution who has written extensively about drones. He was not involved in the new research.

That study, by the Armed Forces Health Surveillance Center, which analyzes health trends among military personnel, did not try to explain the sources of mental health problems among drone pilots.

But Air Force officials and independent experts have suggested several potential causes, among them witnessing combat violence on live video feeds, working in isolation or under inflexible shift hours, juggling the simultaneous demands of home life with combat operations and dealing with intense stress because of crew shortages.

“Remotely piloted aircraft pilots may stare at the same piece of ground for days,” said Jean Lin Otto, an epidemiologist who was a co-author of the study. “They witness the carnage. Manned aircraft pilots don’t do that. They get out of there as soon as possible.”

Dr. Otto said she had begun the study expecting that drone pilots would actually have a higher rate of mental health problems because of the unique pressures of their job.

Since 2008, the number of pilots of remotely piloted aircraft — the Air Force’s preferred term for drones — has grown fourfold, to nearly 1,300. The Air Force is now training more pilots for its drones than for its fighter jets and bombers combined. And by 2015, it expects to have more drone pilots than bomber pilots, although fighter pilots will remain a larger group.

Those figures do not include drones operated by the C.I.A. in counterterrorism operations over Pakistan, Yemen and other countries.

The Pentagon has begun taking steps to keep pace with the rapid expansion of drone operations. It recently created a new medal to honor troops involved in both drone warfare and cyberwarfare. And the Air Force has expanded access to chaplains and therapists for drone operators, said Col. William M. Tart, who commanded remotely piloted aircraft crews at Creech Air Force Base in Nevada.

The Air Force has also conducted research into the health issues of drone crew members. In a 2011 survey of nearly 840 drone operators, it found that 46 percent of Reaper and Predator pilots, and 48 percent of Global Hawk sensor operators, reported “high operational stress.” Those crews cited long hours and frequent shift changes as major causes.

That study found the stress among drone operators to be much higher than that reported by Air Force members in logistics or support jobs. But it did not compare the stress levels of the drone operators with those of traditional pilots.

The new study looked at the electronic health records of 709 drone pilots and 5,256 manned aircraft pilots between October 2003 and December 2011. Those records included information about clinical diagnoses by medical professionals and not just self-reported symptoms.

After analyzing diagnosis and treatment records, the researchers initially found that the drone pilots had higher incidence rates for 12 conditions, including anxiety disorder, depressive disorder, post-traumatic stress disorder, substance abuse and suicidal ideation.

But after the data were adjusted for age, number of deployments, time in service and history of previous mental health problems, the rates were similar, said Dr. Otto, who was scheduled to present her findings in Arizona on Saturday at a conference of the American College of Preventive Medicine.

The study also found that the incidence rates of mental heath problems among drone pilots spiked in 2009. Dr. Otto speculated that the increase might have been the result of intense pressure on pilots during the Iraq surge in the preceding years.

The study found that pilots of both manned and unmanned aircraft had lower rates of mental health problems than other Air Force personnel. But Dr. Otto conceded that her study might underestimate problems among both manned and unmanned aircraft pilots, who may feel pressure not to report mental health symptoms to doctors out of fears that they will be grounded.

She said she planned to conduct two follow-up studies: one that tries to compensate for possible underreporting of mental health problems by pilots and another that analyzes mental health issues among sensor operators, who control drone cameras while sitting next to the pilots.

“The increasing use of remotely piloted aircraft for war fighting as well as humanitarian relief should prompt increased surveillance,” she said.

In a Slight Shift, North Korea Widens Internet Access, but Just for Visitors

HONG KONG — North Korea will finally allow Internet searches on mobile devices. But if you’re a North Korean, you’re out of luck — only foreigners will get this privilege.

Cracking the door open slightly to wider Internet use, the government will allow a company called Koryolink to give foreigners access to 3G mobile Internet service by next Friday, according to The Associated Press, which has a bureau in the North.

The North Korean police state is famously cloistered, a means for the government to keep news of the world from its impoverished people. Only the most elite North Koreans have been allowed access to the Internet, and even they are watched. And although many North Koreans are allowed to have cellphones, sanctioned phones cannot call outside the country.

Foreigners were only recently allowed to use cellphones in the country. Previously, most had to surrender their phones with customs agents.

But it is unlikely that the small opening will compromise the North’s tight control of its people; the relatively few foreigners who travel to North Korea — a group that includes tourists and occasional journalists — are assigned government minders.

The decision, announced Friday, to allow foreigners Internet access comes a month after Google’s chairman, Eric E. Schmidt, visited Pyongyang, the North’s capital. While there he prodded officials on allowing Internet access, noting how easy it would be to set up through the expanding 3G network of Koryolink, a joint venture of North Korean and Egyptian telecommunications corporations. Presumably, Mr. Schmidt’s appeal was directed at giving North Koreans such capability.

“As the world becomes increasingly connected, their decision to be virtually isolated is very much going to affect their physical world, their economic growth and so forth,” Mr. Schmidt told reporters following his visit. “We made that alternative very, very clear.”

North Koreans will get some benefit from the 3G service, as they will be allowed to text and make video calls, The Associated Press said. They can also view newspaper reports — but the news service mentioned only one source: Rodong Sinmun, the North’s main Communist Party newspaper.

Italy Set to Vote for a New Parliament

ROME — As Italian voters head to the polls on Sunday and Monday to elect a new Parliament and three regional governments, the prevailing mood is one of anger and disillusionment.

The fledgling, anti-establishment parties that campaigned on promises of radical change could benefit from the voters’ discontent, but the lack of a clear winner could also leave Italy mired in uncertainty.

“Italians feel frustration, anger, but also some hope for renewal,” said Nicola Piepoli, who runs a polling company. They are frustrated, he said, because their taxes are rising but they see no improvements in their “economic and social life,” and they are angry because candidates did not address “concrete problems” during the campaign, focusing instead on “futile, absurd things.”

“But many still hope for some change,” Mr. Piepoli added, explaining the growing support for populists like the comedian Beppe Grillo and his Five Star Movement, and for smaller parties like Civil Revolution, led by Antonio Ingroia, a former prosecutor, and Act to Stop the Decline, a movement guided by Oscar Giannino, a journalist.

Mostly though, the mood is dark among Italians fed up with protracted political scandals and disinclined to believe election promises because they are so rarely fulfilled.

(On Friday, former Prime Minister Silvio Berlusconi, campaigning to return to office, made a new promise: he said that if he won, he would personally refund an unpopular property tax paid by Italians in 2012. “I will take four billion euros of my own fortune and give it to Italians,” he said on television, a pledge of about $5.3 billion.)

“There’s no one to vote for, and if I went to the polls I’d choose the least-worst candidate, so I prefer not to vote,” said Concetta Rossi, a recruiter for hotel employees in Rome. “It’s never been this bad.”

The center-left Democratic Party, led by Pier Luigi Bersani, a low-key former industry minister, is expected to place first but is unlikely to win enough seats to govern without a coalition. The centrist movement backing the current prime minister, Mario Monti, is a possible ally, but even together they might not prevail in the Senate because the electoral law allocates seats based on regional votes. Lombardy and Sicily, where polls suggest that the right is strong, are crucial.

For the past year, Mr. Bersani, a former Communist who has played up his Catholic upbringing, has supported Mr. Monti’s reformist agenda, though sometimes grudgingly. He has backed Mr. Monti’s commitments to the European Union for greater fiscal responsibility, but would review policies that might have hurt workers and retirees.

Investors and economic analysts have their own concerns about the potential instability that could emerge in the absence of a strong government.

In its 15 months in office, Mr. Monti’s technocratic government tried to pass much-needed reforms, but it failed to stimulate the economic growth required to pull Italy out of a persistent recession. On Friday, the European Commission said in its winter forecast that Italy’s economy would shrink by 1 percent in 2013, double its November estimate.

Gains made by anti-establishment parties, including the Five Star Movement, could stall Mr. Monti’s overhauls, and a strong showing by the center-right party led by Mr. Berlusconi could derail the austerity measures meant to keep Italy on a fiscally responsible track.

“The fear remains that the general election produces a significant no-confidence vote on the current austerity plan and the need to reform further,” Raj Badiani, an economist with IHS Global Insight, wrote in a research report last week. “Without the prospect of a stable coalition government with a credible reform agenda, Italy could be forced to reconstruct a technocratic government to keep the markets at bay.”

Alessandro Amadori, the director of Coesis, which conducts marketing and opinion polls, said the “emotional mapping” of Italy highlighted the population’s “disenchantment and rage,” and even its resignation. “People don’t think that much will change. They hope for a sign, but they don’t have high expectations.”

Mr. Amadori added: “These elections will probably mark a moment of transition, rather than long-term change. Italians are looking for something that will shake things up, but what will emerge, we still don’t know.”

Common Sense: Mindful of Bubbles as Deal-Making Boom Begins

Warren E. Buffett has teamed up with 3G Capital to buy the venerable H. J. Heinz Company for $23 billion. But the famed value investor isn’t exactly buying low: when the deal was announced on Valentine’s Day, Heinz shares were trading at a record high of nearly $61. Had Mr. Buffett and his partners bought a year ago, shares were selling for $53, a 13 percent discount.

Mr. Buffett is hardly the only buyer pursuing deals now that the stock market is hitting levels last seen in 2007. The Wilshire 5000 index recently set a record, and the Dow Jones industrial average has pierced 14,000 several times in the last three weeks.

Thomson Reuters reports that during the first two months of 2013 there have been over a thousand deals valued at almost $163 billion in total. That’s more than double the amount for the same months in 2012. If this blistering pace continues, merger and buyout deals could surpass $2 trillion in 2013, far more than the $1.57 trillion in 2007.

We all know what happened after that. From its peak in October 2007, the Standard & Poor’s 500-stock index plunged 56 percent.

“Buy low and sell high” is probably the most common adage in investing. So why do so many highly paid chief executives of acquiring companies persist in doing the opposite?

Mr. Buffett, it should be said, may be the exception that proves the rule, since he’s been among the few willing to make big deals when stocks are cheap.

His company, Berkshire Hathaway, completed a $34 billion purchase of Burlington Northern in November 2009, when the S.& P. 500 hit an 11-year low. It surely ranks as one of the best deals ever, since stocks generally, and railroad stocks in particular, have surged since then.

Mr. Buffett kept busy throughout the downturn, buying profitable stakes in Goldman Sachs and General Electric in the depths of 2008 while also bolstering investor confidence.

But even Mr. Buffett can get swept up in a deal-making frenzy. He called his 2007 investment in the Texas utility TXU bonds a “huge mistake” and “unforced error.” The $45 billion TXU buyout, led by Kohlberg Kravis Roberts, a veteran deal maker and buyout firm, still ranks as the biggest leveraged buyout ever — and may turn out to be one of the worst.

“You always see a lot of M.& A. activity when the market is overvalued,” Matthew Rhodes-Kropf, an associate professor at Harvard Business School who has studied the phenomenon and also advises private equity and venture capital firms. “Of course, you only know a market peak with benefit of hindsight. But when you look back, you’ll see a lot of M.& A. activity.”

One reason is that there has to be two sides to every deal, and, “When prices are low, sellers don’t want to sell,” Professor Rhodes-Kropf said. “They know their stock will go up with even modest growth. All they have to do is hang on.”

The same thing happened after the recent real estate crash, when owners withdrew their homes from the market rather than sell at fire-sale prices, and the number of transactions plunged.

Conversely, as stock prices rise, some executives start to worry about their ability to meet investors’ growth expectations and whether their stocks are getting overvalued, Professor Rhodes-Kropf said. A merger or buyout may provide an attractive option, both for the seller, who can cash in at a premium, and the buyer, who gets immediate revenue gains and may benefit from the growth prospects at the newly acquired company.

Professor Rhodes-Kropf’s research suggests that mergers and buyouts occur disproportionally in overvalued industries and overvalued companies.

Still, that doesn’t explain why so many mergers and buyouts occur when the stock market is as overvalued as it turned out to be in both 2000 and 2007. You’d expect sellers to be plentiful, but not buyers.

Stephen A. Schwarzman, chairman and chief executive of Blackstone Group, one of Wall Street’s best-known and most successful deal makers, told me this week that early in the merger cycle: “You typically buy companies that are in the same industry or where there’s a fit. Those deals tend to be smart, pretty reasonable, and they usually work.”

Question Mark: Acne Common in Baby Boomers Too

Pimples are no surprise on babies and teenagers, but boomers?

You no longer have to gaze over a school lunchroom, hoping to find a seat at a socially acceptable table. You don’t rush to get home at night before your junior license driving restrictions kick in. And you men no longer have to worry that your voice will skip an octave without warning.

But if adolescence is over, what is that horrid protuberance staring at you in the mirror from the middle of your forehead? Some speak of papules, pustules and nodules, but we will use the technical term: zit. That thing on your forehead now is the same thing that was there back in high school, or at least a close relative. Same as it ever was (cue “Once in a Lifetime”).

We get more than the occasional complaint here from baby boomers who want to know about this aging body part or that. So you would think people would be happy with any emblem of youth — even if it is sore and angry-looking and threatening to erupt at any second. But oddly, there are those who are not happy to see pimples again, and some have asked for an explanation.

Acne occurs when the follicles that connect the pores of the skin to oil glands become clogged with a mixture of hair, oils and skin cells, and bacteria in the plug causes swelling, experts say. A pimple grows as the plug breaks down.

According to the American Academy of Dermatology, a growing number of women in their 30s, 40s, 50s and even beyond are seeking treatment for acne. Middle-age men are also susceptible to breakouts, but less so, experts say.

In some cases, people suffer from acne that began in their teenage years and never really went away. Others had problems when they were younger and then enjoyed decades of mostly clear skin. Still others never had much of the way of pimples until they were older.

Whichever the case, the explanation for adult acne is likely to be the same as it is for acne found in teenagers and, for that matter, newborns: hormonal changes. “We know that all acne is hormonally driven and hormonally sensitive,” said Dr. Bethanee J. Schlosser, an assistant professor of dermatology at Northwestern.

Among baby boomers, the approach of menopause may result in a drop in estrogen, a hormone that can help keep pimples from forming, and increased levels of androgens, the male hormone. Women who stop taking birth control pills may also see a drop in their estrogen levels.

Debate remains over what role diet plays in acne. Some experts say that foods once thought to cause pimples, like chocolate, are probably not a problem. Still, while sugar itself is no longer believed to contribute to acne, some doctors think that foods with a high glycemic index – meaning they quickly elevate glucose in the body — might. White bread and sweetened cereals are examples. And for all ages, stress has also been found to play a role.

One message to acne sufferers has not changed over the years. Your mother was right: don’t pop it! It can cause scarring.

IHT Rendezvous: North Korea Widens Internet Access, but Just for Visitors

DealBook: Carlyle's Profit Fell in 4th Quarter as Growth Slowed

11:18 a.m. | Updated Most of the publicly traded private equity giants proudly reported glowing fourth-quarter earnings.

The Carlyle Group isn’t one of them.

On Thursday, the alternative investment giant disclosed a 28 percent drop in fourth-quarter profit from the period a year earlier, as the growth of its portfolio companies slowed. That sent the company’s stock down more than 8 percent by midmorning, to $33.70.

Carlyle reported fourth-quarter profit of $182 million, expressed as economic net income, compared with $254 million in the year-earlier period. That amounts to 47 cents per unit. Analysts surveyed by Capital IQ had expected about 66 cents per unit, on average.

And Carlyle’s distributable earnings, a measure the firm prefers because it tracks actual payouts to its limited partners, fell 24 percent, to $188 million. Using generally accepted accounting principles, Carlyle earned $12 million in net income.

The results fall short of those of rivals like the Blackstone Group and Kohlberg Kravis Roberts. Private equity firms in general have gained from improvements in the markets, which have lifted the valuations of their portfolios and bolstered their core business of buying and selling companies.

Carlyle attributed the decline in economic net income to a smaller appreciation in the value of its portfolio. It reported a 4 percent gain for the quarter, compared with a 7 percent increase in the period a year earlier.

The decision to delay reaping carried interest from its latest mainstay fund, Carlyle Partners V, weighed on distributable earnings. The company opted to hold off, given the relative freshness of the fund and the influx of new investments like the buyouts of the TCW Group and Getty Images.

Carlyle highlighted its strong fund-raising and gains from selling investments. The firm raised $4.6 billion in new money for the quarter and $14 billion for the year, compared with a total of $6.6 billion raised in all of 2011. It generated $6.8 billion in realized proceeds for the quarter and $18.7 billion for the year, compared with $17.6 billion in 2011.

“We had another excellent year,” David M. Rubenstein, one of Carlyle’s co-chief executives, said in a statement. “Our performance over the past two years was marked by steady, continuous progress across our business.”
