The working capital finance industry has operated on a regional and local basis for many years. There has been a consolidation that has resulted in fewer effective commercial lenders which are capable of providing sound working capital financing in response to cost-cutting that has permeated many industries. This has happened in a relatively short period of time, and most business owners have been understandably confused about what this might mean for the future of their business financing efforts.

Obtaining accurate working capital advice is often difficult for small business owners. The rapidly-increasing number of economic and financial changes recently has further magnified the complexity of this challenge. There have been some unexpected and disappointing responses by business lenders to recent economic circumstances. The Working Capital Finance Journal is evaluating some of the commercial finance actions taken by business lenders as part of a straightforward effort to create a central clearinghouse of relevant information for business owners.

Small business owners should make a sincere effort to learn more about what is happening and what to do about it once they come to the realization that major changes are likely for business finance funding in the near future. Analyzing actions recently taken by business lenders should be a primary part of such an effort. The Working Capital Journal is one prominent example of a free public resource providing working capital help and facilitating a better understanding of the responses by business lenders to recent economic circumstances.

Because they have been excluded from obtaining any new business financing by many banks, some businesses such as restaurants are having an especially difficult time in surviving recently. The continuing effectiveness of merchant cash advance programs to obtain working capital quickly has been reported by The Working Capital Journal, and this is one of the few bright spots in recent business financing. This commercial financing approach should be actively considered for most businesses accepting credit cards. Merchant cash advance programs are effectively saving the day for many business owners after most banks have done a terrible job of providing working capital help and business loans in the midst of chaotic financial and economic conditions. Banks are not routinely providing sufficient small business financing help for restaurants and many other businesses. However, if a restaurant accepts credit cards in their business operations, they are likely to be able to obtain needed cash from merchant cash advances and credit card factoring.

Of course, for some time there have been ongoing complex problems for commercial borrowers to avoid when seeking commercial loans and working capital advice. Because even more uncertainties still appear to be present in the economy, this has produced a new set of business finance problems. It seems increasingly likely that prior standards for working capital finance and small business finance will continue to change rapidly and with very little advance warning from lenders.

White Rot Fungi Slowed Coal Formation

News | Evolution

The evolution of the ability to break down a plant's protective lignin largely stopped the geologic burial of carbon that formed present-day coal deposits?and may provide secrets to making biofuels from inedible parts of plants

Why do testicles hang the way they do? Is there an adaptive function to the female orgasm? What does it feel like to want to kill yourself? Does ?free will?...

Read More??

A toughened crosshatch of carbon-based molecules is all that stands between plants and their total destruction at the hands of an array of microbes and fungi. Called lignin, the compound enables redwoods to tower and woody herbs to resist rot. As a result, lignin is the second-most abundant biological compound on the planet?and the bane of would-be biofuel-makers everywhere, blocking their best efforts to make fuels from the inedible parts of plants. It is also the reason for the vast deposits of coal laid down millions of years ago.

Now a new genomic analysis suggests why Earth significantly slowed its coal-making processes roughly 300 million years ago?mushrooms evolved the ability to break down lignin. "These white rot fungi are major decomposers of wood and the only organism that achieves substantial degradation of lignin," explains mycologist David Hibbett of Clark University in Massachusetts, who led the research published in Science on June 29.

By comparing 12 newly sequenced genomes of mushroom fungi with 19 existing genomes, the researchers determined that an ancestral white rot fungi (Agaricomycetes) first evolved the ability to break down lignin. The scientists then used so-called "molecular clock analysis"?a dating technique based on the hypothesis that genes accumulate mutations at a relatively regular rate like trees form rings that record their growth. Such an analysis suggests that an ancestral white rot fungi developed this lignin-degrading ability roughly 290 million years ago, a conclusion backed by comparison with the appearance in the fossil record of three other types of fungi (although the first definitive white rot fossil does not appear until roughly 260 million years ago) and the subsequent expansion and refinement of the arsenal of enzymes employed. The 60-million-year-long Carboniferous period?when the bulk of the world's coal deposits were laid down and atmospheric CO2 levels declined?ended roughly 300 million years ago.

The coincidental timing suggests the appearance of this ability to break down lignin helped slow the massive burial of organic carbon via nondegraded tree trunks and other wood, such as the lignin-rich fernlike plants known as arborescent lycophytes, now extinct. Previous explanations largely argued that such coal formation was a result of the Carboniferous's swampy conditions?after lignin-rich plants fell into these swamps, they simply were buried rather than broken down by fungi or microbes and turned to peat and then coal over geologic time frame. "They're not mutually exclusive," Hibbett notes, although more of the easily overlooked fungal fossils would need to be found to determine the truth.

How exactly white rot breaks down lignin remains unknown. The fungi releases reactive molecules and enzymes that seemingly tear the plant-protecting compound apart via "brute force," in the words of Hibbett. Once the protective lignin is out of the way, the white rot fungi feast on the cellulose, which comprises more digestible plant sugars. And subsequent evolution has given so-called brown rot fungi the means to work around lignin without attacking it directly. "They have evolved a way to get at cellulose and leave the lignin behind," Hibbett says, which results in the crumbly, brown logs littering temperate forests today?potentially coal in the distant future.

Exclusive: Lucy Hale Is Going Country On First Album

'I grew up in Tennessee, so that's always been my heart and soul,' the 'Pretty Little Liars' star tells MTV News.
By Kara Warner

"Pretty Little Liars" star Lucy Hale is expanding her horizons beyond her successful acting career and spreading her wings to (hopefully) soar into an equally successful music career.

The multitalented 23-year-old recently inked a recording deal with Hollywood Records, which is the same label that brought us the chart-topping vocal stylings of Miley Cyrus and Demi Lovato.

MTV News was lucky enough to sit down with Hale recently for an exclusive chat about how she came to land a recording contract with Hollywood Records and what plans she has for her first album.

"Some people know, some people don't know: I grew up performing, I grew up singing, and I never knew which route I was going to take," said Hale, who first showcased her singing skills on the talent competition "American Juniors" in 2003. "Acting took off for a while and I booked ['Pretty Little Liars'], and I did a movie last year, 'Cinderella Story: Once Upon a Song,' and I played a singer, and so that's sort of how Hollywood [Records heard me]."

Hale then landed a meeting with Hollywood Records head Ken Bunt, who was eager to work with her and wanted to make the music Hale was most passionate about.

"I told him [I wanted to sing] country, so I'm going to do a country/pop album, and I couldn't be more excited," she said. "I grew up in Tennessee, so that's always been my heart and soul. It's hard to come across a true country fan in L.A., but it's true that the fans are so loyal, once you're in their circle, you're in for your entire career. It just really speaks to me. Country music has so much soul and is so heartfelt. I think it's a perfect fit for me. I think it will surprise people."

So which country singers does Hale look to for inspiration?

"I love all [kinds of country artists], but comparing what my sound would be like? A Taylor Swift/ Carrie Underwood-ish hybrid? Obviously, I would kill to have their music careers," she said. "I'm not saying I will have that career, but sound-wise, I would say it's closest to that."

Look for Hale's first country album to hit the airwaves sometime next year.

Google's Nexus 7 cover turns on the Play store, will set you back $20

Not surprisingly, Google will have some accessories for its new Nexus 7 tablet, including a cover that also leaked out a bit early through Google Play (and spotted by MoDaCo's Paul O'Brien). As you can see, it will cover both the front and back of the device, and set you back a fairly reasonable $20. Available at least in dark grey, it has a matte (seemingly textured) finish, and provides access to both the tablet's headphone jacket and charging port.

How Print Marketing Can Aid Your Business Growth | Make Money ...

Business marketing is a massive topic, and digital formats such as the internet, television and radio often dominate as the preferred choice for many companies. But I?d like to ignore the technological methods for just now, and discuss the beneficial power of offline marketing in the form of printed materials through business printing services.

The term ?printed materials? refers to a variety of promotional and every day-use business items ? brochures, business cards, postcards, posters, letterheads and compliment slips, as well as advertising through magazines, newspapers and billboards. Whilst we often take for granted the authority these materials pose, they?re marketing power is actually quite remarkable, and here?s why:

Building The Brand

Branding should be a top priority for businesses, as it is the key ingredient to achieve familiarity and loyalty with consumers. This fact is clearly demonstrated by the many corporate brands that are well known for their logos/slogans. For example ? the slogan ?Because you?re worth it? makes you immediately think of L?Oreal, just as similar as ?The best a man can get? with the Gillette brand.

Branding works just as powerfully with logo designs and this is where printed materials have the upper hand. You can saturate the market with brand designs through the various distributions of printed items causing potential consumers to subconsciously form a memory of your identity. Once they have that association between brand and services or products, there is automatically a sense of credibility that gives the consumer comfort and the willingness to proceed with a purchase.

Physical Presence

Printed materials are a physical item, not digital. This is a distinct advantage in a number of areas; the first being disposability. Online spam ads are easy to ignore, you click a button and they?re gone, plus the fact that you can?t take everything you read online as factual information. You just never know these days. A flyer or brochure for example is physically put in front of your potential consumers, and if the design has the power to entice them to have a look then you?ve already jumped the first hurdle. More often than not, some people may have a quick read and keep the document for later reference, should they need it.

Another major benefit here is the ease of reading. You have the document in your hands and you can clearly see the full effect of the text and design ? you don?t need to scroll down to read the full text. Couple this with the fact that online users generally have a shorter attention span, a physical printed material is ultimately better.

Targeting A Market

Again, most businesses will be aware of how to contact their target markets, and this can be implemented into the distribution of printed promotional materials. There are several methods of doing this ? whether it?s through using a development geo-targeting tool or by placing your flyer into an appropriate magazine/newsletter, but in each instance your marketing material lands directly into the hands of your target market, leaving them to make the decision whether to proceed with enquiries.

How far you extend your target marketing geographically will depend on your type of business and your budget for business printing services, and whilst response can be far slower with this marketing method, any response is always a good thing right? More often than not it has proved an invaluable tool and one every business should look to be executing.

A Less Intrusive Method

We are daily subject to digital advertising ? adverts that interrupt our TV or radio programs or that disturb our time surfing the internet. We have no control over this type of advertising, which in most cases can cause some annoyance. Printed marketing allows consumers full control as to when they pick up the article to read it, and whether they decide to act on it. In a growing cautious society, this is a gentle technique that will not waver any judgment about your business and have the simple job of letting your consumers know you are out there.

Send The Message

The design of a brand and the way in which it is presented can cause an instant reaction and first impression, and this is the strongest point of any type of marketing as it captures an audience and entices them to continue reading or find out more about your business. This applies to items like business cards, postcards and brochures ? if you were to be presented with a flimsy reproduction of a promotional piece of printed material, would you hold a credible impression of the business?

Probably not. A quality piece of promotional material has a lasting impression on anyone who sees it, and similarly can be the difference to whether a person decides to pick it up and read it or not.

Do quality substrates cost more? Perhaps. However, most business printing services have a vast choice of materials allowing the business to choose one that can both represent their image and be friendly on the bank balance. Plus the fact that most print companies can offer significant discounts for bulk orders or business packages, so the savings argue this point quite clearly.

Let?s not cloud the reality of this topic and forget the aid of digital marketing, as it is equally important, but just a gentle reminder that these traditional print marketing methods have not outlived themselves just yet! Business printing services can produce all the promotional items you need, then with the joint effort of online marketing you can guarantee to achieve the maximum level of exposure your business deserves. Then it?s time to sit back and enjoy the rewards as you steadily climb one step of the ladder to reach success.

Syria warns NATO against action over Turkish plane

ANKARA/BEIRUT (Reuters) - Syria described its shooting down of a Turkish warplane as an act of self-defense and warned Turkey and its NATO allies against any retaliatory measures.

In shell-shattered districts of Homs, heart of a 16-month-old revolt against President Bashar al-Assad, rebels battled troops as aide workers tried to evacuate civilians. Turkish television reported the desertion of a Syrian general and other officers across the border.

Syria's account of Friday's shooting down, though tempered with commitment to a "neighborly relationship", seemed likely to further anger Ankara, which has summoned a NATO meeting on Tuesday over what it calls an unprovoked attack in international air space.

"NATO is supposed to be there to strengthen countries," Syrian Foreign Ministry spokesman Jihad Makdissi told a Damascus news conference. "If their meeting is for hostile reasons (they should know that) Syrian land and waters are sacred."

Turkey say the wreckage of the aircraft, shot down close to the Mediterranean maritime borders of both states, is lying in deep water. Makdissi said some flotsam had been found and turned over to Turkey. There was no word on the two airmen. ID:nL5E8HO0II]

"The plane disappeared and then reappeared in Syrian airspace, flying at 100 meters altitude and about 1-2kms (0.6-1.2 miles) from the Syrian coast," he said. "We had to react immediately, even if the plane was Syrian we would have shot it down."

"The Syrian response was an act of defense of our sovereignty carried out by anti-aircraft machinegun which has a maximum range of 2.5 km."

In Ankara, Turkish air force chiefs briefed both President Abdullah Gul, the commander of the armed forces, and the cabinet on what Prime Minister Tayyip Erdogan said would be a "decisive" response. Turkey also said it would take the matter to the United Nations Security Council.

EU CONDEMNATION

Though not known for his emotional restraint, Erdogan has eschewed bellicose rhetoric over the incident, aware perhaps of Western reluctance to commit to any military action and wary himself of anything that could trigger a regional sectarian war.

According to Ankara's account, the aircraft entered Syrian airspace briefly and by mistake while on a mission to test Turkish air defenses.

Some analysts have suggested it might in fact have been testing the responsiveness of Russian-supplied Syrian radar that would be a major obstacle to any foreign intervention, including supply of Syrian rebels or reconnaissance support.

"I'm not of the opinion that Turkey will immediately respond militarily," agreed Beril Dedeoglu of Galatasaray University. "But if there is another action, then there will certainly be a military response, there is no doubt."

Erdogan turned against former ally Assad after he refused his advice to bow to demands for reform. He now allows the rebel Free Syrian Army (FSA) to use Turkish territory as a safe haven, though Ankara denies supplying arms.

Over 30,000 refugees are also accommodated On Turkish soil.

After Friday's attack, Erdogan invoked an article in NATO's founding treaty providing for urgent consultations if a member considers its security interests threatened.

Had he sought some kind of retaliation from the NATO meeting set for Tuesday, he could have invoked another article on mutual defense. That he did not, suggests the reaction will remain at least for now, on the diplomatic stage.

European Union foreign ministers meeting in Luxembourg called for a calm response from Turkey, saying they would increase pressure on Assad.

"Military intervention in Syria is out of the question," said Dutch foreign minister Uri Rosenthal. "It is not a matter of consideration for the Dutch government. That is also at stake in the ... context of NATO."

DEFECTIONS

The International Committee of the Red Cross (ICRC) said it was again trying to arrange a safe evacuation of trapped civilians from Homs. But anti-government activists reported heavy shelling on central districts, including Jouret al-Shiyah and al-Qarabis. Video showed detonations and machinegun bursts from the skeletal shells of abandoned apartment blocks.

The activist Syrian Observatory for Human Rights said Assad's troops carried out raids and arrests in areas still under army control, and heavy fighting between government forces and rebel fighters was reported in the opposition centers of Idlib, Deir al-Zor and Deraa, the birthplace of the uprising.

"In Deraa, regime regular troops are trying to reassert control of some villages with heavy shelling, gunfire and helicopters firing missiles," the Observatory said in an email. "People are fleeing villages because they know the army is trying to push out the rebels," it said.

A Syrian general, two colonels, two majors, a lieutenant and their families - altogether 199 people - crossed the border into Turkey overnight, CNN Turk said. Thirteen Syrian generals are now in Turkey which is giving logistical support to the Free Syrian Army.

The new defections from Assad's armed forces could encourage those awaiting a disintegration of Assad's army. But there has been little indication of a broader trend to desertion in senior ranks, bound often to Assad by their Alawite background.

Alawites make up 90 percent of the officer corps. Such Sunni generals as there are tend to serve in administrative roles rather than field commands, their religious adherence making them in authorities' eyes more likely to sympathize with Sunni rebels.

The United Nations has said more than 10,000 people have been killed by government forces, while Syria has said at least 2,600 members of the military and security forces have been killed by what it calls foreign-backed "Islamist terrorists."

The intensification of the fighting has raised fears in Turkey of a flood of refugees and a slide into ethnic and religious warfare that could envelop the region. Ankara, like the West, is torn between a wish to remove Assad and the fear that any armed intervention could unleash uncontrollable forces.

WiFi alliance begins hardware testing on Passpoint cell-to-hotspot roaming program

WiFi alliance begins hardware testing on Passpoint cell-to-hotspot roaming programIt was over a year ago now that we heard about the WiFi Alliance's intention to certify hotspots and simplify the potential for mobile handovers. Now, it's just announced hardware testing of its WiFi-CERTIFIED Passpoint program, which promises to let phones and mobile devices automatically discover and connect to compatible networks. The specification used is the result of cooperation between service providers and equipment manufacturers, with the aim of creating an industry-wise solution for shared WiFi access and roaming agreements. Already hardware from the likes of Cisco, Intel, MediaTek and Qualcomm has received Passpoint certification, leaving the ball in the court of service providers, once testing is complete.

One of the keys to be able to tips for potty training a whole new pup is regularity. You need to consistently coach your puppy you?re responsible, very similar to a genuine wrap up boss can. Satisfying training sessions will that a dog recalls everything you taught and it is wanting to give back to get more within the future period.

Pricier an excessive amount the dog, prematurily .. Only take your canine?s identify any time delivering instructions. You will notice that your canine will pay much more focus an individual when they are used and also content. You may achieve far better outcomes in case you work with a single expertise, accomplish expertise then move on. When you?ve got got a fresh puppy or perhaps new puppy, you ought to work on teaching these folks immediately.

Your dog will not have an understanding of negative weather. Cease a training program together with your pet should you turn out to be mad with it. This is simple however will be handy to your pet dog to find out, specifically when you want to have her particular attention.

In case you have targets noted on your work schedule it may possibly offer you a way to measure how you?re progressing while using dog training, and gives a person suggestions about whether or not you?ll have to switch everything in the plan. Avoiding articles and also difficulty, take little steps in establishing oneself as being the pack head. Replication is probably the most crucial areas of training any dog. And then available the door as well as produce any strict ?No!? Most dogs desire a nicely installing receiver and lead should they be to be a master. Minus the consistent run associated with hormones, a pet dog is a bit more docile and sensitive to the innovator.

Announcing ?Come? currently and announcing ?Come here? your next, inside the puppie?s mind, is similar to educating 2 distinct directions, on the other hand, the behaviour is anticipated to be exactly the same. Just featuring your puppy ways to conduct themselves just once only can be unsuccessful. Pets react a lot better to people these people believe in, so just go chuck your tennis ball, play pull of conflict or simply wipe the waist. If you find yourself teaching your dog, make sure to are extremely affected person.

Discovery of material with amazing properties

ScienceDaily (June 24, 2012) ? Normally a material can be either magnetically or electrically polarized, but not both. Now researchers at the Niels Bohr Institute at the University of Copenhagen have studied a material that is simultaneously magnetically and electrically polarizable. This opens up new possibilities, for example, for sensors in technology of the future. The results have been published in the scientific journal, Nature Materials.

Materials that can be both magnetically and electrically polarized and also have additional properties are called multiferroics and were previously discovered by Russian researchers in the 1960s. But the technology to examine the materials did not exist at that time. It is only now, in recent years, that researchers have once again focused on analyzing the properties of such materials. Now you have research facilities that can analyze the materials down to the atomic level.

Surprising test results

"We have studied the rare, naturally occurring iron compound, TbFeO3, using powerful neutron radiation in a magnetic field. The temperature was cooled down to near absolute zero, minus 271 C. We were able to identify that the atoms in the material are arranged in a congruent lattice structure consisting of rows of the heavy metal terbium separated by iron and oxygen atoms. Such lattices are well known, but their magnetic domains are new. Normally, the magnetic domains lie a bit helter-skelter, but here we observed that they lay straight as an arrow with the same distance between them. We were completely stunned when we saw it," explains Kim Lefmann, Associate Professor at the Nano-Science Center, University of Copenhagen.

They were very strange and very beautiful measurements and it is just such a discovery that can awaken the researchers' intense interest. Why does it look like this?

Explaining physics

The experiments were conducted at the neutron research facility Helmholtz-Zentrum in Berlin in collaboration with researchers in Holland, Germany, at ESS in Lund and at Ris?/DTU. They would like to get a general understanding of the material and with the help of calculations; and have now arrived at a more precise image of the relationship between the structure of the material and its physical properties.

"What the models are describing is that the terbium walls interact by exchanging waves of spin (magnetism), which is transferred through the magnetic iron lattice. The result is a Yukawa-like force, which is known from nuclear and particle physics. The material exhibits in a sense the same interacting forces that hold the particles together in atomic nuclei," explains Heloisa Bordallo, Associate Professor at the Niels Bohr Institute.

It is precisely this interaction between the transition metal, iron, and the rare element, terbium, that plays an important role in this magneto-electrical material. The terbium's waves of spin cause a significant increase in the electric polarization and the interaction between the ions of the elements creates one of the strongest magneto-electrical effects observed in materials.

"Through these results we found a new pathway to discover and develop new multiferroics," emphasize the researchers in the group. Now it is up to further research to determine whether this new effect could lead to new applications of these materials with the amazing physical properties.

Twitter's Not Singing About Outage Details

Twitter was unavailable to users for significant portions of the day on Thursday. Contrary to speculation, it wasn't due to a hack attack, despite attempts by some groups to claim responsibility. Rather, a "cascading bug" in one of its infrastructure components was the cause for the upheaval, Twitter said.

Analysis: Wave of departures raises BlackRock questions

BOSTON/NEW YORK (Reuters) - A series of high-level departures from BlackRock this month has raised questions about the direction of the world's largest money manager.

Coming in rapid succession over the past two weeks, the departures included Susan Wagner, a founding partner and vice chairman, who will retire at the end of June, and Robert Capaldi, who has already left and was senior client strategist for Chief Executive Laurence Fink.

New York-based BlackRock also announced the departures of two of the firm's most prominent portfolio managers, chief equity strategist Bob Doll and energy sector fund star Daniel Rice. Rice will help transition some of his funds, a process that is expected to last through December and Doll will retire at the end of month, BlackRock said.

Wagner's departure was the most significant of the four as it further signals the end of growth through large acquisitions for BlackRock, according to two people with knowledge of the situation.

One of the original partners of the firm, Wagner joined from the Lehman Brothers mortgage department when Fink opened for business in 1988. Frequently named to published lists as one of the most powerful women in business, Wagner will join BlackRock's board of directors where she will continue to have a say on strategy, spokeswoman Bobbie Collins said.

Some BlackRock employees are worried Wagner's departure may signal bigger changes or further departures from the firm, possibly including Fink moving into a government role, according to two people familiar with the situation. One of these people, and another person familiar with the situation, said further senior-level changes are expected in the coming weeks.

"People are speculating that Sue is stepping down because Larry is going to make a move for government," said the person, who declined to be identified because he was told this in confidence. For the past several months, rumors have been circulating that Fink is a candidate for U.S. Treasury Secretary if President Barack Obama is re-elected in November.

There's also concern about how BlackRock is handling the other departures. For example, client relationship managers at BlackRock, whose job it is to assuage investors' concerns, did not have any talking points to discuss regarding the Rice situation after it became known that he would be leaving, according to one person who spoke to a client relationship manager at the firm, and declined to be identified because the conversation was confidential.

"People are getting client calls and they have no talking points," the person said.

BlackRock has maintained that most of the changes were part of the firm's necessary restructuring after digesting two huge mergers in the past six years and growing to a previously unprecedented size of $4 trillion.

Three years ago, BlackRock absorbed Barclays Global Investors and its $1.8 trillion of assets, doubling the firm overnight. That followed the 2006 acquisition of almost $600 billion in Merrill Lynch's fund division.

CEO Fink has lately been saying that he is done with mega-mergers for the foreseeable future. Formerly BlackRock's head of corporate strategy, Wagner coordinated acquisition activity including the Barclays deal and the Merrill buy.

BlackRock spokeswoman Collins said the recent departures among fund managers and senior staff were not related. "The personnel changes people are seeing are neither related nor a trend," she said.

Investors have so far brushed off the departures. Shares of BlackRock rose 5.3 percent over the past month, outpacing the S&P 500's 1.5 percent gain.

As Wagner departs, BlackRock has made several recent high-level hires with a non-U.S. focus. Former Swiss central bank chairman Philipp Hildebrand, who quit that post after a controversy involving his wife's currency trading, joined as vice chairman. And Mark McCombe, who was Chief Executive Officer in Hong Kong for HSBC, came on board as BlackRock's Chairman for Asia-Pacific.

Capaldi's advisory role was eliminated when he left, BlackRock said, but his prior role heading the firm's U.S. and Canadian institutional business was filled in 2011 by the hire of Edwin Conway, a senior managing director from private equity shop Blackstone.

The end of mega-mergers is likely good news for BlackRock clients. Industry experts wonder if some of BlackRock's recent issues, particularly the questions regarding energy fund manager Rice, stem from failures in oversight due to the big mergers in recent years.

Rice left in the wake of a potential conflict of interest that involved his family business. The energy mutual funds Rice had co-managed at BlackRock increased their holdings in Alpha Natural Resources after that company formed a joint venture with a unit of a natural gas drilling company founded by Rice.

"It is hard to explain how if they knew about (the Rice situation), they were okay with it," said Russ Kinnel, director of mutual fund research at Morningstar. "The mergers may have left some gaps in their compliance."

Doll, who joined BlackRock in 2006 when it acquired Merrill Lynch's money management unit, will retire at the end of June. In January, BlackRock removed language from the prospectus of Doll's funds stating that they used "proprietary" quantitative investment models, instead saying the models came from "third-party research firms.

And two of Doll's three funds, BlackRock's Large Cap Core Fund and Large Cap Value Fund , have trailed the performance of the vast majority of similar funds over the past three years.

BlackRock CEO Fink has a history of moving on quickly when fund managers disappoint.

"We're very confident in Larry Fink," said Macrae Sykes, an analyst at Gabelli & Co in Rye, New York. "He will swiftly and appropriately address any issues with underperformance or reputational risk."

"Compliance and reputational care are very, very important to BlackRock," BlackRock spokeswoman Collins said.

The recent string of departures may concern financial advisers who work with BlackRock, Kinnel said. BlackRock has said it wants to double its retail mutual fund business to $600 billion by the end of 2014, largely by targeting registered investment advisers.

"It's not yet to the point where this will send advisers fleeing, but it doesn't give you a particularly good feeling," Kinnel said.

15 Berlin adventures your family will love

Torsten Seidel / Courtesy VisitBerlin

The Badeschiff, a swimming pool installed atop an old barge docked on the Spree River, is a top summer attraction for Berliners.

By Marisa Robertson-Textor, Budget Travel

With miles of bike lanes, quirky pop-up museums, a massive hotel boom and some of the world?s tastiest street food, Berlin is drawing a new breed of traveler: families.?


Slideshow: See Berlin's best all-ages attractions

Berlin is likely to evoke vastly different images depending on when you came of age: the concrete and barbed wire of the Berlin Wall (1960s to '80s), Mike Myers's??ber-bored performance artist Dieter on "Saturday Night Live"?(1990s), or a hipster paradise of avant-garde art galleries, after-hours dance parties, and cheap rent (2000s). But it's safe to say that few people would have predicted Berlin's latest claim to fame. Beyond the roving burlesque shows and underground supper clubs, this sprawling metropolis has become one of the best places on the continent to have ? and be ? a kid.?

Berlin's softer side has been nurtured from many sources. For one thing, it has good, kid-friendly bones, in the form of abundant parks and sidewalks wide enough to accommodate most baby-stroller traffic jams. Add that to the government's pro-family work-life policies and the laid-back vibe that's accompanied its rise as the "Silicon Allee" of Europe and you end up with a youthquake unlike anything the city has seen in decades. With a massive new international airport opening this year, the crowds will undoubtedly keep coming.

?

The city is already experiencing the kind of tourism explosion most destinations only dream of. In 2010, hotel stays in Germany were up 11.9 percent, with Berlin accounting for 41 percent of the bookings. In fact, Berlin has passed Rome to become the third-most-popular European city for visitors, after London and Paris. So what happens when an epicenter of cool is overrun by vintage 1960s Silver Cross prams? How do you explore this edgiest of European cities with?kinder?in tow? Here are some of our favorite stops in the new Berlin ? all grown up, and ready for the whole family.?

1.?Pick up a bike

About half a million Berliners take to their bikes each day, so you'll be in good company on one of?Berlin on Bike's rentals. Choose from city, touring and trekking bikes, all of which come with rear baskets. Even the kids can get a set of wheels, with three sizes of smaller cycles as well as child seats and trailers (reserve in advance) and helmets for all. A free route planner on?bbbike.de?helps you map paths through the city based on your desired speed, road surface and the availability of designated bike lanes, of which Berlin has some 400 miles.?Kulturbrauerei, court 4,?berlinonbike.de, $13 for 24 hours.?


2.?Make the most of breakfast

Breakfast is to Berlin as dinner is to Barcelona: an opportunity to dress up and visit with family and friends over an endless parade of tempting little dishes. Only here, you don't have to stay up late to partake. A true?Fr?hst?ck?is no small-scale continental affair: It's a cornucopia of savory salads, cold cuts, eggs, cheeses, fruit, and freshly baked breads and pastries piled high on a tiered tray. For a classic version that's as beautiful as a Renaissance still life, head to?Anna Blume, a caf?-cum-flower shop in Prenzlauer Berg. On weekends, arrive early to claim a table on the leafy terrace (the people-watching is worth it), then let your morning meal stretch into the afternoon just like the locals do. If the kids get antsy, you can always take them to the playground at Kollwitzplatz, one block away, to clamber over wooden structures shaped like enormous vegetables.?Kollwitzstrasse 83,?cafe-anna-blume.de, Fr?hst?ck for two $23.?

  • Berlin transit tip: Flying in
    This year, the Berlin Brandenburg Airport will make its debut, replacing Berlin Tegel as the city's international airport and nearly doubling its passenger capacity. (Both of the city's existing airports, Tegel and Schoenfeld, will close once Brandenburg is operational.) AirBerlin, Lufthansa, and other airlines plan to boost their traffic to coincide with the opening, including new nonstop routes between Los Angeles and Berlin, and a 20-minute rail shuttle will connect Brandenburg's terminals with downtown.

3.?See the writing on the Wall
For almost 30 years, the most potent symbol of the Cold War was the 96-mile Berlin Wall. Today, less than a mile of it remains, and it's all at the?East Side Gallery?(eastsidegallery.com), a freedom memorial that runs along the Spree River in Friedrichshain. Originally completed in 1990, many of the more than 100 paintings have recently been restored by their creators (with more updates scheduled). Yet while Wall art is (thankfully) a dead art form, wall art is everywhere. Berlin is an urban canvas, full of fences, fa?ades and subway cars featuring the graffiti of local taggers and international artists alike, some of whom (Banksy, Swoon, Blu) sell similar work on the world art market. Online magazine?Berlin Graffiti?(berlingraffiti.de) keeps tab of the newest tags, while Benjamin Wolbergs's "Urban Illustration Berlin: Street Art Cityguide"?($30, Gingko Press) contains artist interviews, a pull-out map of key pieces and snapshots of over 500 of the city's most compelling works.?

4.?Climb around in a church
Not all art in Berlin is conspicuous. The?MACHmit! Museum for Children?(which roughly translates to "join in!") hides within a converted Protestant church and is outfitted with Bauhaus-inspired climbing shelves, fun-house mirrors and a series of hands-on arts and crafts and cooking exhibits (Senefelderstrasse 5,?machmitmuseum.de, $6). Transit geeks with good timing can immerse themselves in the history of the city's subway at the pop-up?Berliner S-Bahn-Museum, hosted by a group of train enthusiasts in a former railway station the second weekend of the month, from spring through autumn (S-Bahn Griebnitzsee,?s-bahn-museum.de, adults $2.75). There, guests can play conductor behind the wheel of a drive simulator modeled on century-old technology.??

5.?Refuel on the cheap
Prenzlauer Berg and Mitte may be boutique- and stroller-filled neighborhoods now, but they were once the center of the East Berlin resistance. The counterculture ethos still exists in pockets, including?FraRosa Weinerei?(wine bar), one of three related honor-system restaurants in Berlin where patrons pay what they will (really) for everything from lunch to tea and cakes to four-course dinners of German specialties made with organic ingredients?and, of course, wine (Veteranenstrasse 14,weinerei.com).?Honigmond Kaffeehaus-Restaurant?charges a bit more, though $9 for its wonderful, all-you-can-eat lunch buffet is still a bargain. Besides, the lovely corner bistro has had a fascinating life: Before the Stasi secret police raided it in the late '80s, it was the unofficial headquarters of the East German opposition movement (Borsigstrasse 28,?honigmond.de/restaurant.html).

  • Berlin transit tip: Going underground
    Although the city's once-bisected subway system has been reconnected, crossing town on the U-Bahn remains a challenge. The first rule of riding: Know your zones. There are three in the city (A, B and C), and failing to pay for all those you travel through could get you in big trouble with the undercover inspectors who roam the cars. For most trips you'll only need zone A, or A and B (about $3 each way), while airport trips call for a three-zone fare ($4).

6.?Explore an animal planet
Built on the site of the 18th-century pheasantry that once supplied fowl to the King of Prussia's royal kitchen, the 168-year-old?Zoological Garden?was Germany's first zoo and, with 17,727 animals, has one of the most diverse populations in the world. Savvy visitors will want to sync their trips with the feeding times of their favorite animals (pandas at 11:30 a.m. and 3 p.m., penguins at 1:45 p.m.), or splurge on a private, 20-minute visit with a single species, complete with zookeeper Q&A. And be sure to keep an eye out for the zoo's newest arrival, Kathi, a baby hippopotamus born in October.?Hardenbergplatz 8,?zoo-berlin.de, from $29.50 for a family ticket; private tours an additional $107.?

7.?Find a street's sweet spot
Every Berliner has a favorite secret street, a place like the cobblestoned Gr?festrasse in Kreuzberg. The four-block-long stretch serves as a microcosm of the modern city: here,?Kad?, a highly focused candy store that sells 400 varieties of licorice ? and nothing else (Gr?festrasse 20,?kado.de, licorice from $2.10); there,?Lilli Green, an eco-minded design shop that stocks the shelves with "upcycled" objects such as pencils made of old Japanese newspapers and storage baskets fashioned from recycled car tires (Gr?festrasse 7,?lilligreen.de, pencils 12 for $7). And then there's?Little Otik, a rustic New American restaurant whose out-of-the-shadows evolution mirrors Berlin's own. Its owners, New York transplants Kevin Avery and Jeffrey Sfire, started hosting by-appointment dinners for 10 in their pop-up supper club in February 2009, then decided to take their underground sensation public, with a changing menu of seasonal dishes such as white bean and farro soup, grass-fed rib eye with bone marrow butter, and date and almond pie with vanilla ice cream (Gr?festrasse 71,?littleotik.de, entrees from $12).?

8.?Dive into a splashy swimming pool
If you didn't know better, Berlin might be one of the last places on earth you'd think about taking a dip. But it happens to be a swimmer's paradise ? and one for all seasons. In winter, residents have their pick of 37 local?Stadtbads?(municipal pools), perhaps the most spectacular of which is in the gritty-but-gentrifying Neuk?lln district (Ganghoferstrasse 3,?berlinerbaederbetriebe.de, $5.25). Built in 1914 and expanded in 1999, the Roman-style bathhouse is decked out with marble columns, soaring ceilings and fountains, plus two heated pools and a sauna. Come summer, the crowds shift to the?Badeschiff,?a swimming pool installed atop an old barge docked on the Spree River (Eichenstrasse 4,?arena-berlin.de/badeschiff.aspx, $5.50). It's connected to land by a series of piers, where cocktail bars, a mini-spa and a "beach" of trucked-in sand spring up each season.?

9.?Skip the line at the Reichstag
No visit to Berlin would be complete without a tour of the Neoclassical Reichstag building, constructed in the late 19th century to house the German parliament before being ravaged by fire, bombed in war and abandoned as the seat of government in favor of Bonn. Following reunification in 1990, the Reichstag reverted to its original use, its renovations crowned by an iconic glass dome that yields sweeping panoramic views of the city 800 feet below. But entry to the building, while free, comes with a price: punishingly long lines. Avoid the wait by booking afternoon tea at the glass-walled rooftop?K?fer Caf?, adjacent to the dome. After you've called ahead and made a reservation, enter the Reichstag through the handicapped entrance to the right of the building's west portal, then speed straight to the top.?Platz der Republik 1,?feinkost-kaefer.de, pastries from $1.25.?

  • Berlin transit tip:?Getting lost
    If it seems like there's no address system in Berlin, well, there are two. The city initially opted for horseshoe-style numbering (up one side of a street and back down the other), and shifted in the 1920s to evens on one side, odds on the other. Our best navigation tip? Always ask for the cross streets.
10.?Make a day trip of it
Nature lovers don't have to leave the city limits to dabble in pastoral pleasures. From the Gr?nau S-Bahn in southeast Berlin, hop on streetcar No. 68, perhaps Germany's most scenic, and hurtle east through a corridor of green to?Alt-Schm?ckwitz, a tiny village at the end of the line that's bordered by three lakes (bvg.de, tram $3 each way). Or head west: Two miles from the Brandenburg border, the?Waldsee Sculpture Garden?is an al fresco arts gold mine (Argentinische Allee 30;?hausamwaldsee.de, $9.25). There are works by contemporary German artists such as the late bronze sculptor Karl Hartung (who is getting a solo show this summer), and Ina Weber, who created an interactive mini-golf course outfitted with models of architectural ruins as obstacles. For an instant escape in the heart of the city, look no further than Berlin's newest, and largest, park: 990-acre?Tempelhof?airport, site of the 1948-49 Allied air lift that supplied food to West Berlin during the Soviet blockade (U-Bahn to Platz der Luftbr?cke). Its defunct runways have been repurposed for bicycle races and kite-flying contests, and pick-up baseball games take place on the ramshackle diamonds where U.S. troops once played.?

?

11.?Have a food-cart feast
Hamburgers, falafel, even tacos ? Berlin has them all. But for the city's best street food, check out two homegrown fusion dishes concocted decades before the term came into vogue. Currywurst, a sliced pork sausage served with a curry-laced dipping sauce, was first developed to make use of the British food products supplied to West Berlin after World War II. Some of the best in town is available seconds after you arrive: Head to the?EsS-Bahn?kiosks housed inside picturesque vintage streetcars just outside the main terminals at both Tegel and Sch?nefeld airports (berlin-airport.de, $4). When you're ready for the next course, make a beeline to Kreuzberg, where the Turkish immigrants who started settling in the area in the 1960s took their native spit-roasted lamb and savory sauces and turned them into the now-iconic d?ner kebab sandwich. For a twist on that classic, check out the version at?Mustafa's: crisp flatbread stacked with delicately spiced chicken and shredded vegetables (Mehringdamm 32,?mustafas.de, $4).?

12.?Learn a new move
Berlin has dance clubs (underground, after-hours and otherwise) for every taste, fetish and demographic. For longevity, however,?Cl?rchens Ballhaus?has them all beat. A bona fide Berlin institution, it's been in the business since 1913 (and appears to still attract some of its first-wave clientele). Head over early for a group tango, salsa, or swing lesson, whirl the kids around until they drop sleepily into a corner, then keep on dancing until dawn ? doors won't close until the last guest leaves.?Auguststrasse 24,ballhaus.de,?lessons from $4.?

13.?See a silent film
Berlin is chock-a-block with specialty cinemas, many of which show classic Hollywood films in English. But you could see those at home, couldn't you? For a one-of-a-kind theater experience that still won't get lost in translation, buy a ticket for a silent-film screening at the?Babylon?in Mitte, where the musical accompaniment might be the movie's original score performed live on piano or a local DJ spinning trance music.?Rosa-Luxemburg-Strasse 30,?babylonberlin.de, silent-film screenings $8.75.?

14.?Sleep like a movie star
Immerse yourself deeper still into the glamorous world of?Stummfilm?(silent movies) by staying at?Hotel-Pension Funk, a 14-room inn located in the former home of silent film actress Asta Nielsen. Its graceful, Jugendstil chandeliers, antique wardrobes, and original architectural details (vast art nouveau windows, decorative moldings) will transport you to a bygone era ? albeit one blessed with free Wi-Fi.?Fasanenstrasse 69,?hotel-pensionfunk.de, from $68 for doubles with a shared bath, breakfast included.?

15.?Or find a home away from home
For an even funkier stay, book the "band room" at the?Michelberger Hotel, in a converted factory. With five single beds, a lofted sleeping area, a dining table, and big windows overlooking the communal courtyard, it feels like playing house in the best way.?Warschauer Strasse 39/40,?michelbergerhotel.com, doubles from $78, band room from $155.
