A billboard featuring a meme-style juxtaposition of President Obama and Aurora shooter James Holmes has garnered a great deal of attention, very little of it positive.
The billboard, located in Caldwell, Idaho, features a picture of Holmes, accompanied with the text “Kills 12 in a movie theater with assault rifle, everyone freaks out.”
Juxtaposed is a photo of Barack Obama, with the text: “Kills thousands with foreign policy, wins Nobel Peace Prize.” Check out the controversial billboard below:
The sentiment is similar to one of Heath Ledger's memorable Dark Knight quotes, in which he says no one would blink if he announced a “truck load of soldiers will be blown up," but people would "lose their minds" if he said a city mayor was going to die."

Scientists probe link between magnetic polarity reversal and mantle processesPublic release date: 30-Jul-2012 [ | E-mail | Share ]

Scientists at the University of Liverpool have discovered that variations in the long-term reversal rate of the Earth's magnetic field may be caused by changes in heat flow from the Earth's core into the base of the overlying mantle.
The Earth is made up of a solid inner core, surrounded by a liquid outer core, in turn covered by a thicker or more viscous mantle, and ultimately by the solid crust beneath our feet. The magnetic field is generated by the motions of the liquid iron alloy in the outer core, approximately 3,000 km beneath the Earth's crust. These motions occur because the core is losing heat to the overlying solid mantle that extends up to the crust on which we live.
The mantle itself is also in motion but at much slower speeds of millimetres per year as opposed to millimetres per second in the core. This mantle motion is responsible for the drifting of the continents at the surface as well as earthquakes, volcanoes, and changes in the climate over millions of years.
At intervals of hundreds of thousands of years, the North and South magnetic poles reverse and scientists can tell from rock formations precisely at what periods in the past this took place. The most recent reversal happened 780,000 years ago. Magnetic field variations happen on timescales of months to millions of years. Much of the magnetic field's variation is thought to be sporadic but new research, led by Liverpool scientists, has found that over long timescales, this variability may be related to the changing pattern of heat loss across the core-mantle boundary occurring over millions of years.
The team performed a detailed synthesis based on latest findings from a number of different areas including the ancient geomagnetic field and its record in rocks, motions in the mantle caused by motions of the continents and the process responsible for generating the magnetic field in the core.
Dr Andrew Biggin, from the University's School of Environmental Sciences, said: "The magnetic field has undergone big changes in its behaviour that might be due to the mantle's controlling influence on the core. In particular, we focused on the time interval between around 200 and 80 million years ago when dinosaurs were still around when the magnetic field initially started reversing its polarity very
frequently. During this period the polarity was reversing up to 10 times every million years; however 50 million years later, it stopped reversing altogether for nearly 40 million years.
"When these changes in the magnetic field were taking place, the whole of the Earth's crust and mantle, including all of the continents, were undergoing a big rotation with respect to the geographic and time-averaged geomagnetic poles the points defining the Earth's axis of rotation. We suspect that this process, called True Polar Wander and caused by the changing density distribution in the mantle, will have changed the pattern of heat flowing out of the core in such a manner as to cause the magnetic field to first become less stable, with lots of reversals, and then become much more stable and stop reversing."
The team believes this may not be the only explanation and conjecture that this big drop in the frequency of reversals may also be related to a similar decrease in the number of 'large igneous provinces' (LIPs) or concentrated outpourings of magma from the Earth's core, 50 million years later. The last LIP happened around 16 million years ago and produced the Columbia Plateau in the North West US. LIPs are thought to be produced by hot plumes of material rising from thermal instabilities near the bottom boundary of the mantle.
The team believes the 50 million year time lag between the magnetic field changing and the occurrence of the LIPs could represent the time it takes for the plumes to travel 2,890 km through the mantle. If this link were correct it would mean that the rather unstable magnetic field observed in the last 50 million years predicts that a considerable number of LIPs will erupt over the next 50 million years. This in turn could have major implications for the surface conditions for climate and for life itself.

LONDON -- Add LeBron James to the list of players who don't want to see the London Olympics become the last one before a restrictive age cap is instituted for men's basketball, limiting the tournament to those 23 or younger.
"I disagree with that," he said.
Why?
"Because I'm 27," he said with a smile.
The charmingly made point illustrated a widespread feeling among the superstar players on Team USA -- that although they might be jet-setting millionaires dozens of times over, they still crave representing their country at the Olympics.
"I feel like we should definitely have a choice," forward Kevin Love said. "When the time comes, I know that they'll make a decision. But my stance is that the players should have the right to choose if they want to play in the Olympics, because this might only come around once."
The Americans take on lightly regarded Tunisia in their next game Tuesday.
But in the aftermath of a blowout opening win over France, several players cited forward Blake Griffin in their defense of an Olympic status quo, in the face of suggestions by NBA Commissioner David Stern and some team owners to impose an age limit.
The 23-year-old Griffin was chosen for the Olympic team, but lost the opportunity when he had to back out because of a knee injury suffered during training camp.
"He couldn't play in 2016, if that goes into effect," said Chris Paul, his teammate on the Los Angeles Clippers.
The
players are competing on the 20th anniversary of the original "Dream Team" at the 1992 Barcelona Games, the first Olympics at which NBA professionals were allowed to compete. Until then, the men's basketball competition was limited to amateurs and pros from Europe and South America.
It has never had an age limit, per se.
But Stern and owners such as Mark Cuban want to both curtail the risk of injury to players to whom NBA teams are paying vast salaries, and create a "World Cup" of basketball from which they can make more money than they do from the Olympics.
The idea harkens to men's soccer, which does have a 23-year-old age limit in the Olympics, in large part because the giant European clubs have resisted allowing their top stars to play in yet another international competition.
But even the head of the international soccer federation, Sepp Blatter, has encouraged young soccer stars to take a stand against their teams if they want to play in the Olympics. Blatter cited superstar Lionel Messi, who played at the 2008 Beijing Olympics as a 21-year-old against the wishes of Barcelona FC and won the gold medal with Argentina.
"Everyone should embrace the spirit and play in the Games if they want to," Blatter said. "The problem is that the national associations are not making the right contacts with the clubs. I think the players themselves would like to come."
The basketball players seem to demonstrate that.
Paul said he doesn't see a change happening, and even Stern has acknowledged the issue isn't an urgent one. USA Basketball chairman Jerry Colangelo said he doesn't expect anybody to seriously study the issue until after the London Olympics.
But Kobe Bryant has been among those most vocal about his opposition, originally calling the idea of an age limit "stupid," and contesting the notion that owners need a hedge against injuries.
Bryant said it's more likely for players to get hurt playing pick-up games during the offseason against "a bunch of bums" than during the Olympics, when players are closely monitored as they would be during the NBA season.
"To me, playing on an Olympic team is actually better, if I was an owner," he said.
Beyond that, Bryant said, the Americans can't expect to compete against the rest of the world if they use only younger players. It was an amateur team's failure to win gold at the 1988 Seoul Olympics in Korea, after all, that led to the creation of the Dream Team, and everybody agrees that other countries have only grown stronger since then.
"We'll be in trouble," Bryant said. "Guys playing against us will be grown men and we'll be in trouble. If you just look at the Olympics as a whole, it's about putting your best athletes to the front to showcase. That's what it's about. If an athlete doesn't want to play, that's his decision. If a team feels some type of way [about] him performing, it's the team's responsibility to have those conversations with the athlete. That's how it should be.
"I don't see why it's even a topic of discussion," he said.
From halal spas to prayer rooms at airport terminals, the global tourism industry is gearing up for a projected boom in Muslim travel over the next decade, experts say.
Their growing number and affluence means Muslims -- especially from the oil-rich Middle East -- are travelling like never before, and it is a trend that looks set to gather pace.
Spending by Muslim tourists is growing faster than the global rate and is forecast to reach $192 billion a year by 2020, up from $126 billion in 2011, according to a study by two companies specialising in the market.
The study, made available to AFP, was conducted in 47 countries by Singapore-based halal travel specialist Crescentrating, along with DinarStandard, a US-based firm that tracks the Muslim lifestyle market.
Crescentrating chief executive Fazal Bahardeen said Muslim-majority states such as Egypt, Malaysia and Indonesia were already favourite destinations, but non-Islamic countries are now "taking a serious look" at Muslim holidaymakers.
Malaysia, the number-one destination according to the findings, attracts Muslim visitors even during the ongoing fasting month of Ramadan.
Mohammed Ali Alali, 23, a petroleum engineering student from Dammam, Saudi Arabia, went there on honeymoon with his bride, a 20-year-old medicine student.
"It's not that far from Saudi Arabia and it's less expensive to travel here rather than Europe. It's also an Islamic country so that helps in many ways, like to find a mosque and Arabic food," he said after breaking fast at an Arabic restaurant in the capital Kuala Lumpur.
The availability of halal food tops the list of Muslim travellers' requirements, according to the survey.
Destinations such as Thailand and Australia, especially the Gold Coast, are already taking into account these travellers' needs in their services and facilities, Fazal told AFP.
That includes prayer rooms at airports and hotels, halal restaurants and even spas adapted to religious requirements.
"Why not try Gold Coast for a cooler Ramadan this year?" says the tourism website of Australia's Queensland state.
"With a long history of welcoming Middle Eastern visitors and a large resident community, facilities for Muslims in Gold Coast, Australia keep getting better every year."
The Economist Intelligence Unit said in a March report that meeting the needs of the world's 1.8 billion Muslims is fuelling business opportunities in numerous sectors.
"From food and Islamic finance, the industry is spreading its wings into pharmaceuticals, fashion and tourism, among many other areas," it said, noting more than half of the world's Muslim population is aged 24 or younger, many of them well-educated.
Thailand is hungrily eyeing the Muslim travel boom.
Its tourism authority --- which has an office in Dubai -- is promoting halal spas for Muslim tourists, who require strict privacy for male and female clients.
It also organised a month-long festival of Thai cuisine in the United Arab Emirates from June 8 to July 7.
Crescentrating's study ranked Bangkok's Suvarnabhumi Airport the most Islam-friendly airport in a non-Muslim country.
And it found that tourists from the Gulf -- Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the UAE -- are the sector's biggest spenders.
Gulf countries accounted for 37 percent of Muslim tourist spending in 2011 even though they represent a mere three percent of the global Muslim population.
LONDON, July 29 (UPI) -- He Zi and Wu Minxia began what is expected to be a Chinese dominance of diving at the Olympics Sunday by winning the three-meter synchronized gold medal.
Chinese divers won seven of the eight gold medals awarded at the Beijing Olympics and the first competition in the sport at these Games was not close.
He and Wu piled up 346.20 points and finished more than 20 points in front of Americans Kelci Bryant and Abigail Johnson.
The silver medal won by Bryant and Johnson, however, was the first in diving for the United States in 12 years. Once a power in the sport, the Americans had not won a diving medal since Laura Wilkinson was the winner on the 10-meter platform at the Sydney Olympics.
Jennifer Able and Emilie Heymans of Canada won the bronze, finishing five points behind the Americans.
Heymans became the first female diver in Olympic history to win a medal in four straight Olympics. She captured a silver medal in the individual platform event in Beijing along with a silver and bronze in synchronized platform at the two Olympics before that.
Wu, 26, is the most decorated of the powerful Chinese team.
This was her third straight Olympic gold in synchronized springboard and she has both a silver and bronze medal in individual springboard. She has won six world championships since 2001.
China won all eight diving events at this year's world championships and now has claimed 13 of the last 16 gold medals handed out at the Olympics.
Ready for another supposed look at the next-gen Apple iPhone? Matching up with previousleaks we've reported on, the elongated iPhone body with a miniaturized docking port and brushed metal back has appeared again, this time courtesy of iLab Factory. While many of its parts look astoundingly similar to what we've already seen, this is the first time we've gotten a solid look at it fully assembled from all angles -- well, aside from the missing SIM card holder. While most of its all-important innards are clearly absent, this assembly does come complete with what appears to be the locking ribbons for the screen and home button. As always, grab the obligatory spoonful of sodium chloride, then check it out for yourself at the gallery and links below.
Embracing the principles of new urbanism, Mayfaire Town Center is a shining example of a successful master-planned commercial/residential development.? Located a few short minutes from Wrightsville Beach, North Carolina, this mixed use shopping and residential development sits on 31 beautifully landscaped acres on Wilmington, NC?s north side, featuring condos and single family homes, multiple dining, shopping and entertainment options, including Wilmington's newest and largest stadium seating movie theater, and lush outdoor spaces designed for human connectivity and interaction.
What sets this development apart is its location ? typically, mixed-use developments of this size and quality are found in much larger metro areas. In a 2004 article from Wilmington?s local newspaper, the Star-News, one of the project leaders was quoted as saying, "Most of these [new urbanism] projects don't occur in markets the size of Wilmington.? When Mayfaire is through...the statement will have been made this project could have been picked up and put in Raleigh. This project could have been picked up and put in Charlotte. It could have been put in the D.C. area.? It will be that nice."
In a new urbanism development, the neighborhood is anchored by a retail town center, surrounded by high density and single family housing with green spaces that connect to each other and to the town center by pedestrian-friendly streets and paths.? Walkability, connectivity and mixed-use diversity are of primary importance. Other organizing principles include quality architecture and design, with an emphasis on beauty and human comfort, beautiful public spaces, a traditional neighborhood structure with a discernible center and edge, and mixed housing, with a range of types, sizes and prices in close proximity to one another.
Mayfaire Town Center features several housing options, including single family homes, chic urban-style condos in the heart of the shopping district, luxury condos just outside the central shopping area, and even luxury apartment homes adjacent to Mayfaire?s commercial area.
The single family neighborhood, called Parkside at Mayfaire, offers a diverse collection of southern architecture in a neo-traditional setting.? Homes feature 10 foot ceilings, state of the art kitchens, Viking appliances, 3 car garages, large wrap-around front porches, and beautiful landscaping.? Parkside?s warm and inviting neighborhood feel is enhanced by tree-lined streets, white picket fences, wide sidewalks, pristine gardens and a public fountain and garden.? The outdoor areas lend themselves to socializing; residents often stroll the sidewalks and visit with neighbors on their spacious front porches.
The second and third floors of several buildings along Mayfaire?s tree-lined shopping district are designed as residential condominiums, with wrought iron balconies overlooking the streets below. Called Mayfaire Townview, these luxury condominiums feature two-bedroom floor plans that range in size from 1,463 to 1,915 square feet, with large, open kitchens, high ceilings, spacious living areas, large balconies, and an emphasis on the relation of outdoor space to the streetscape below.
The Village at Mayfaire, a short walk or bike ride away from Mayfaire Town Center also offers luxury condos.? These condominiums feature 9 or 10 foot ceilings, walk-in closets, sumptuous bathrooms, stainless steel appliances, granite counter tops, French doors and one secured garage.? There are 6 open and airy condo floor plans to choose from, ranging in size from 1200 to 2000 square feet.? Amenities include a clubhouse with billiards room, 25 seat movie theater, weight room, cardio center, aerobics and yoga room, a heated spa and an Olympic-size pool.
And finally, The Reserve at Mayfaire offers luxury one, two and three bedroom apartment homes, featuring private patios, 9 foot ceilings, tiled entryways, walk-in closets, full-size washers and dryers, stainless steel appliances, maple cabinetry, vaulted ceilings, and crown molding.? The complex also offers a junior Olympic sized pool with sundeck, private movie screening room, state-of-the-art fitness center, business center, and features open green spaces, walking trails, and recreational areas, all within walking distance of Mayfaire?s commercial area.
Not only is the housing at Mayfaire Town Center like that of much larger metropolitan areas, the shopping is too.? Wilmington residents no longer have to make the drive to the Triangle area, 2 hours away, to shop at such stores as Williams-Sonoma, Pottery Barn, Barnes & Noble, Chico's, Ann Taylor, J. Crew and many more ? it?s all right here in Mayfaire.? In keeping with new urbanism?s focus on creating pockets of beautiful outdoor space within commercial areas, hardwood trees have been planted next to numerous park benches along the sidewalks to offer shoppers a shady natural respite from the consumer experience, or a second wind before the next burst of window shopping.
With its convenient location, abundant shopping, dining and entertainment options, and cosmopolitan housing options, Mayfaire Town Center has everything residents need to lead a quality, connected lifestyle.? And with all these conveniences, you?ll never have to leave your cozy and comfortable neighborhood.? Of course, you?ll want to, because gorgeous Wrightsville Beach is just 5 minutes away, historic and charming downtown Wilmington is not more than 15-20 minutes away, and for those seeking destinations a little farther afield, the Wilmington International Airport (ILM) is a mere 15 minute drive.
This coastal mixed-use community, with its emphasis on beauty, connectivity, and convenience, where residents work, live and play in the same neighborhood, makes a perfect addition to Southeastern coastal North Carolina?s retirement relocation offerings.

People are always looking for the quickest and fastest way to something. Most people take shortcuts because they want it now. Sure we all want to get home in the shortest route possible, but that?s not the kind of shortcut I?m referring to. The shortcut I?m talking about has to do with the whole getting rich scheme.
So what if you were given an opportunity to make one decision?
It?s an opportunity of choosing a shiny penny or a heavy black briefcase. As you can imagine, the briefcase is filled with neatly piled cash, like what you normally see in movies when the good guys hand over the briefcase to the bad guys for something. Usually the good guys are tricked into? Well you know how the story goes.
You have one of these to choose from, but before you do so (no scam involved if you choose the briefcase), here are descriptions of what both holds.
The heavy black briefcase contains one million neatly piled cash.
The penny on the other hand, will only be a penny until each day progress. Each day that it progresses, it becomes double the amount. So on day two, there will be two cents. On day three, there will be four cents, and so on.
Which do you decide on?
The people who choose the briefcase are those who take shortcuts in life. A million dollar in that briefcase is nice, but it represents an instant gratification.
Did you know that nearly 70% of the people who wins the lottery go broke after a few years later? Many quit their jobs and end up buying luxurious items until the concept of limitation hits them.
The people who choose the penny are those who have patience and work harder each day?and there is no limit to when your penny stops growing exponentially.
When you find yourself gaining the motivation to keep going as see your work comes together, the exponential effect of the shiny penny is no different. Each day, you are motivated to do more than the previous.
There is just something about this energy in motion. When you gain the motivation to do something, you gain the momentum to keep on going. Like a snowball that slides down the hill, it only gets bigger and faster. Your motivation in motion with momentum is no different here.
A short cut to riches is to subtract from our desires
Francesco Petrarch quotes
Like the rolling snowball, it won?t magically turn into a dangerous, unstoppable ball of snow. It needs to be something small at one point. In this case, a single shinny penny.
Your momentum of motivation is dangerous as well when you get it going. Even I am scared of it because you are able to do unimaginable things that you don?t think is possible.
Those who do take shortcut will only face temporary result. There is no quick way of getting to something that will be life fulfilling. Like a shiny penny that grows exponentially, it will take time to build your momentum. You need to do the small things everything in order to get that momentum moving.
The things you do will take time, just as the penny takes time to double itself to a million dollars. As a result, the payout will end up being much greater than someone who were to choose the path of instant gratification.

A compelling new genetic study tracing the origins of immature egg cells, or 'oocytes', from the embryonic period throughout adulthood adds new information to a growing controversy. The notion of a "biological clock" in women arises from the fact that oocytes progressively decline in number as females get older, along with a decades-old dogmatic view that oocytes cannot be renewed in mammals after birth. After careful assessment of data from a recent study published in PLoS Genetics, scientists from Massachusetts General Hospital and the University of Edinburgh argue that the findings support formation of new eggs during adult life; a topic that has been historically controversial and has sparked considerable debate in recent years.
Eggs are formed from progenitor germ cells that exit the mitotic cycle, thereby ending their ability to proliferate through cell division, and subsequently enter meiosis, a process unique to the formation of eggs and sperm which removes one half of the genetic material from each type of cell prior to fertilization.
While traditional thinking has held that female mammals are born with all of the eggs they will ever have, newer research has demonstrated that adult mouse and human ovaries contain a rare population of progenitor germ cells called oogonial stem cells capable of dividing and generating new oocytes. Using a powerful new genetic tool that traces the number of divisions a cell has undergone with age (its 'depth') Shapiro and colleagues counted the number of times progenitor germ cells divided before becoming oocytes; their study was published in PLoS Genetics in February this year.
If traditional thinking held true, all divisions would have occurred prior to birth, and thus all oocytes would exhibit the same depth regardless of age. However, the opposite was found ? eggs showed a progressive increase in depth as the female mice grew older.
In their assessment of the work by Shapiro and colleagues ? published recently in a PLoS Genetics Perspective article ? reproductive biologists Dori Woods, Evelyn Telfer and Jonathan Tilly conclude that the most plausible explanation for these findings is that progenitor germ cells in ovaries continue to divide throughout reproductive life, resulting in production of new oocytes with greater depth as animals age.
Although these investigations were performed in mice, there is emerging evidence that oogonial stem cells are also present in the ovaries of reproductive-age women, and these cells possess the capacity, like their mouse counterparts, to generate new oocytes under certain experimental conditions. While more work is needed to settle the debate over the significance of oocyte renewal in adult mammals, Woods and colleagues emphasize that "the recent work of Shapiro and colleagues is one of the first reports to offer experimental data consistent with a role for postnatal oocyte renewal in contributing to the reserve of ovarian follicles available for use in adult females as they age."

Marketing your own house could be entertaining or possibly a stressful task because you need to ready your property and repair the problems of your dwelling. It is possible to choose all on your own whether or not you wish to sell your home or you should use a realtor to sell your property. Every single option has its own benefits and drawbacks. Because it is your property, you can create a decision all on your own.
If you do not wish being bothered together with selling your residence, and then use a realtor to trade your premises immediately with an affordable price which you or the agent recommend. The realtor will care for all the paperwork and hang the meetings in between you and the client. The agent also works on the open house unless you have time to get it completed. Even when you will lose some funds while using realtor, at least the house will get sold inside the price that you desire and also you don?t need to think about the documents as well as the permits possibly. Everything is organized and in addition handled by the agent.

LOS ANGELES (AP) ? Katherine Jackson is apparently back home, reuniting with Michael Jackson's children after a judge temporarily took away her guardianship because her days-long absence from them.
Paris Jackson tweeted early Thursday morning: "grandma's here! (hash)thankyougod." Katherine Jackson's son Marlon also posted a note on Twitter saying his mother had returned, adding she looked and sound great.
On Wednesday, judge removed her as guardian temporarily and named her grandson Tito Joe "TJ" Jackson as temporary caretaker of the late legend's three minor children amid a bitter family dispute over Michael Jackson's estate.
Superior Court Judge Mitchell Beckloff issued the ruling because she was in Arizona and hadn't spoken with the children in several days. TJ Jackson now has the ability to control the hilltop home where the children live and to take on other supervision duties.
Katherine Jackson told ABC News that the court ruling was "based on a bunch of lies."
"I am devastated that while I've been away, that my children, my grandchildren, have been taken away from me, and I'm coming home to see about that, also," she said reading from a prepared statement.
She denied the suggestion made in court and in court filings to support TJ Jackson's appointment that she was being held against her will.
"I am here today to let everybody know that I am fine and I am here with my children, and my children would never do a thing to me like that, holding me against my will," she said while her children Randy, Janet and Rebbie were seated next to her. "It's very stupid for people to think that."
Beckloff said there was no evidence that Katherine Jackson had done anything wrong but instead it appeared she was being prevented from fulfilling her role as guardian through the "intentional acts of third parties." He didn't elaborate but made the decision after reading court filings in which TJ Jackson expressed concern that Katherine Jackson was being prevented from returning.
He cited a Monday incident in which Janet, Randy and Jermaine Jackson arrived at the children's home and told them they could speak with their grandmother but had to leave with them.
"This was odd and disturbing to me and (the children) and heightened our concern that our grandmother was being prohibited from returning home," TJ Jackson wrote in a sworn statement. The incident turned into a confrontation between two male adults at the house and sheriff's officials say it remains an ongoing battery investigation.
Beckloff listened as attorneys described Katherine Jackson's demeanor as unusual on phone calls placed to the children hours before the hearing.
TJ Jackson's attorney Charles Shultz also revealed in court filings that the children were forced to miss school Wednesday because of concerns about their security.
Beckloff ruled the Jackson children could not leave California without court approval.
Katherine Jackson's attorney Perry Sanders Jr. said after the hearing that he spoke with his client as she was driving back to Los Angeles from Tucson, Ariz., where she had been since July 15.
"She sounded absolutely fine, lucid and her normal self," he said.
Sanders plans to ask the court to reinstate Katherine Jackson as guardian of the children when she is back in Los Angeles. He was looking forward to meeting with her in person on Thursday.
The public battle was revealed early Sunday after a relative reported Katherine Jackson missing, but she was later located safely with other family members in Arizona.
Jermaine Jackson has said his mother was following doctor's orders to cut off communications with the children, who range in age from 10 to 15. He didn't provide further details.
In addition to concerns about the safety of Jackson's children, some of Michael Jackson's siblings have recently called on the executors of his estate to resign.
Randy Jackson appeared Tuesday on Al Sharpton's MSNBC show PoliticsNation and said he believes his brother's will is a fake and that the executors have engaged in criminal activity.
The estate, which recently reported it saw $475 million in gross earnings since Jackson's death in June 2009, has denied wrongdoing and called the accusations "false and defamatory."
Beckloff, who also oversees financial issues affecting Jackson's estate, was initially reluctant to appoint a temporary guardian but changed his mind after hearing from several attorneys who expressed concern about the family's problems.
He made the ruling after hearing TJ Jackson's description of a "strange" conversation he had with Katherine Jackson on Tuesday evening.
"I've never heard my grandmother talk like that," he said reluctantly. "In every way. The sound in her voice. The pauses."
He said some of her speech sounded slurred and she used words that made him wonder if she was speaking in code.
Her son Marlon echoed those concerns on Twitter, complaining that siblings Janet, Randy and Jermaine were keeping her from him.
The children's guardian ad litem, Margaret Lodise, said she spoke with the children and the two oldest, Prince and Paris, supported the appointment of a temporary guardian. Lodise did not ask the youngest son, 10-year-old Blanket, for his views.
Lodise is responsible for overseeing the children's interests in the estate of their father.
Schultz said TJ Jackson didn't want to replace Katherine Jackson as permanent guardian. Still, the judge noted that TJ Jackson would have to petition to become the permanent guardian within 48 hours and added that such a petition might not be heard if Katherine Jackson re-emerges.
Sanders said he would fight any move to have her permanently replaced.
He said he met with Randy and Janet Jackson in Tucson, Ariz., on Tuesday, but he was not allowed to see his client. He said he still hoped the recent events were a misunderstanding, but he described them as "chaos."

If you have recently received a ticket for speeding and you want to learn how you can get the fines reduced and possibly have the ticket thrown out, you are going to want to consult with a traffic lawyer. They can advise you on how to proceed when you have incurred speeding ticket fines. It is always a great idea for you to consult with traffic court lawyers so you can learn how you can reduce any consequences you face for any moving violation citation you receive. Keep in mind that in addition to fines, there are other ways the law punishes those who fail to heed traffic laws; some of these ways include the suspension of driving privileges and points going on your driving record, which accumulate and cause your insurance rates to increase drastically.
Depending on where you received the moving violation, it may not be possible for you to make it to traffic court. You may have received the ticket while you were travelling in another state on vacation or while visiting a loved one. Since the traffic laws vary from state to state, it makes more sense for you to hire a lawyer or some form of legal representation that can help you with your speeding ticket fines. The right traffic lawyer can represent you when you are not able to make it to court and help resolve the situation in your absence.
In many states, there doesn't have to be visual proof such as being caught on tape speeding to justify you being pulled over. If you are pulled over for speeding, you will receive a ticket and all speeding tickets have some kind of price tag attached to them. Speeding ticket fines also vary from state to state and even the smallest infraction can end up costing you a pretty penny.
Although you may think that speeding is not a serious offense, there are rules and laws regulating it for a reason. Driving at the proper speed recommendations and limits helps to prevent motor vehicle accidents and keeps pedestrians safe. Don't assume that you can successfully represent yourself when it is time to go to court, you may end up having to take full responsibility for the offense. By having a traffic defense attorney to negotiate a reduced penalty, they may even be able to help you avoid any penalties all together and protect your driving record.
Have you ever watched one of those commercials where you see people freaking out because they received a ticket? If you knew how much a single point on your driving record would increase your insurance premium every month, you would get upset too. You may think that you can afford to pay a few speeding ticket fines, but you technically are still paying for them long after you have taken care of the tickets. Do yourself a favor and spare yourself all of the drama and stress. Hire a good lawyer to help keep your driving record intact and reduce the consequences of your speeding citations.

Filmmaking today stands on three main pillars: First, there?s the world-famous Hollywood; then there is India?s Bollywood and then there?s Nigeria?s Nollywood. Presently, the comedy genre is rising at a fast clip in Nollywood and Oliver Mbamara, a prolific screenwriter and filmmaker is one of its foremost pioneers. Mbamara, a Nigerian-born lawyer based in America is blazing a hot trail both in creating Nollywood sitcoms and movies and in bringing them to audiences both in Africa and across the Atlantic. His latest work, a dramedy called ?Cultures?, a 17-episode TV series premiered to a raucous reception this past May at a special screening at New York?s Museum of Modern Art (MoMA).
ComedyBeattalks to the trailblazing filmmaker about his work and the future outlook for comedy in Nollywood:
How long have you been a writer and producer of comedy films and what made you decide to embark on that career path?
Oliver Mbamara: I have been writing since my college days back in Nigeria when I belonged in a theater troupe that toured the country presenting plays and music drama. I found it very satisfying to entertain people and make them laugh. It was very natural for me. As time went on this desire grew and I eventually started writing and producing films.
I suppose you consider yourself a Nollywood filmmaker? In what markets are Nollywood films sold?
Oliver Mbamara: The new age Nigerian independent film industry which is popularly known as ?Nollywood? is still developing and undergoing a dynamic evolution. This makes it rather difficult to use the term ?Nollywood? loosely since we are still defining the industry in line with the variety and category of filmmakers and content arising out of the industry.
As for me, I am an independent filmmaker of African origin dwelling on African and immigrant themed stories.
In terms of where Nollywood films are sold, there are no boundaries yet as the audience keeps growing. But marketers are continuing to explore new ways of marketing these films in today?s challenging environment where store sales and theater showings are hugely impacted by the problems of free internet broadcasting and technology for movie piracy. But, African movies are primarily being sold in African stores across many cities. A few online stores like www.NollywoodMovies.com are also springing up to sell these movies.
How big is the comedy genre in the Nollywood?
Oliver Mbamara: The comedy genre in Nollywood is quite big and is quickly outgrowing other genres. Initially, people were drawn to Nollywood films because of the casual but unique stories they offered. But over time, the storylines of most of the other genres became somewhat repetitive and less exciting unlike in comedy where the antics are always fresh and rather endless. I think that in the end people tend to be drawn to light-hearted entertainment.
How many movies have you made so far?
Oliver Mbamara: At least six feature films, two shorts films, and of course 17 episodes of the TV series ? Cultures.
Now tell me about your latest work ?Cultures?. What is the series all about? And how did it all come about?
Oliver Mbamara: Cultures is a new TV comedy-drama series featuring the veteran comedian Chika Okpala (a.k.a: Chief Zebrudaya, alias 4:30). Okpala plays an African chief named Anabaronye who brings a wife to his nephew, Ozobio, in the U.S. because the nephew had not visited his Nigerian homeland since traveling abroad a long time ago. But Chief Anabaronye arrives in the U.S. only to discover that Ozobio is already engaged to a Chinese-American. He then takes matters into his own hands to try to make things ?right.? What then ensues is a catalyst of humorous dramatic conflicts fuelled by differences in ego, values and cultures. More on Cultures is available at www.CulturesTVseries.com .
With respect to how Cultures came about, the short answer is that I have always felt a sense of duty to both people at home and those abroad to tell the stories of the serious challenges and cultural conflicts faced by immigrants in the Diaspora. The desire to share these stories in a lighter-mood was a major factor in the making of Cultures, just as with most of my other works/films.
Is there a message in ?Cultures?? Can someone who?s not a member of the African Diaspora appreciate the movie?
Oliver Mbamara: The core message in Cultures is to try to get people to understand that there is often a cultural explanation for what may at times seem odd in the behavior and attitudes of immigrants. And this is an issue that seems to cut across all immigrant groups and so it is not limited to just members of the African Diaspora.
Where was the movie made? And what was your biggest challenge in making the movie?
Oliver Mbamara: Cultures was produced in the United States although we had to fly in some seasoned veteran actors like Chika Okpala and Frederick Nnorom, from Nigeria to play some of the more culturally based roles. The biggest challenge in making the TV series was the lack of adequate funding.
I and my co-producer Felix Nnorom are still hoping to get sponsors to come aboard and support us to continue telling the story beyond the episodes we have so far.
How are you distributing the movie?
Oliver Mbamara: We are looking forward to getting some television or cable sponsorship and programming. In the meantime because of the high demand from fans and audience to see the series, we have started releasing the first few episodes on DVD as pilots for the remaining episodes which are already complete and ready to go. We recently had a premiere of some initial episodes of Cultures which will be on DVD soon at www.NollywoodMovies.com
We all know that piracy is a big problem for filmmakers and other creative folks. How big a problem is piracy for Nollywood films?
Oliver Mbamara: Piracy is the biggest problem yet for Nollywood films and it really is one that is threatening the very fabric of the industry. Because most Nollywood filmmakers are independent proprietors who finance their projects from their own savings and other sources, piracy tends to hit them pretty hard by denying them the remuneration they need to improve the quality of their films and to produce more films or even to pay the actors working for them. Our hope is that until the piracy problem is somehow brought under control, those filmmakers who love the art will somehow manage to sustain themselves and not be discouraged from generating more content. But right now, it is tough.
Can you describe the nature of the piracy problem in Nollywood and what is the film industry doing about the problem?
Oliver Mbamara: The extent of the piracy problem is so huge that it cannot be addressed in a single interview. But suffice it so say that film industries are working on the problem- as they should. For example, African filmmakers in the United States are forming a guild that would, among other things, battle piracy and improve the industry.
As it happens, modern technology and tools with which to pirate a movie have become commonly available and so movie pirates are now able to stream movies on the internet for free and some of them now even broadcast movies on TV without authorization. But until movie pirates realize that living off another person?s labor and investment is both morally and legally wrong, filmmakers just have to unite and come up with effective means of dealing with the challenge. Movie pirates won?t be going away on their own any time soon.
Is Nollywood collaborating with other film industries (like Hollywood & Bollywood) in trying to deal with the piracy problem? If so, how?
Oliver Mbamara: At the moment, there is no direct collaboration yet but the problem of piracy cuts across the board and all film industries are working on it.
Is there anything about African comedy that sets it apart from, say, American comedy or even oriental comedy from India and such places?
Oliver Mbamara: African comedy is usually woven around African traditional mannerisms and ways of life. That is something unique to Africa just as other industries also add a flavor of their cultural background in their stories.
What is the future outlook for comedy movies in Nollywood?
Oliver Mbamara: The future is bright. Comedy movies have come to stay and the genre will continue to grow because of the freshness of the content when compared to other genres.
Where do you see yourself as a filmmaker in five years? time?
Oliver Mbamara: Telling more of our stories in a more improved way!
New method to encourage virtual power plants for efficient renewable energy productionPublic release date: 25-Jul-2012 [ | E-mail | Share ]
Contact: Glenn Harris G.Harris@soton.ac.uk 44-023-805-93212 University of Southampton
Researchers from the University of Southampton have devised a novel method for forming virtual power plants to provide renewable energy production in the UK.
In the last decade, small and distributed energy resources (DERs), like wind farms and solar panels, have begun to appear in greater numbers in the electricity supply network (Grid).
To ensure that energy demand is met without interruptions, the Grid requires power suppliers to provide an estimate of their production and the confidence in meeting that estimate. Depending on the confidence placed on the estimates, the Grid is able to choose the appropriate number of conventional generators needed to produce and supply energy whenever it is needed - the more accurate the provided estimates, and the higher the confidence placed in those estimates, the better for the Grid scheduling activities.
Although the deployment of DERs could reduce reliance on conventional power plants, their integration into the Grid is problematic since the DERs, given their small size, are largely 'invisible' to the Grid. Even if visible, the uncertainty and uncontrollability of renewable energy sources prevents individual DERs from profitably dealing with the Grid directly, or participating in the wholesale electricity market because they are often unable to meet the set generation targets.
Virtual Power Plants (VPPs) are fast emerging as a suitable means of integrating DERs into the Grid. They are formed via the aggregation of a large number of such DERs, enabling them to reach similar size and supply reliability as conventional power plants.
In a new study, University of Southampton researchers promote the formation of such 'cooperative' VPPs (CVPPs) using intelligent and multi-agent software systems. In particular, they designed a payment mechanism that encourages DERs to join CVPPs with large overall production.
Dr Valentin Robu, from the University's Agents, Interaction and Complexity Research Group, who worked on the study says: "There is considerable talk about how to integrate a large number of small, renewable sources into the grid in a more efficient and cost effective way, as current feed in tariffs, that simply reward production are expensive and ineffective.
"CVPPs that together have a higher total production and, crucially, can average out prediction errors is a promising solution, which does not require expensive additional infrastructure, just intelligent incentives."
By using a mathematical technique called proper scoring rules (a scoring rule, is a measure of the performance of an entity, be it person or machine, which repeatedly makes decisions under uncertainty), intelligent software agents, representing the individual DERs, are incentivised to report accurate estimates of their electricity production.
The researchers devised a scoring rules-based payment mechanism that incentivises the provision of accurate predictions from the CVPPs - and in turn, the member DERs - which aids in the planning of the supply schedule at the Grid. The mechanism guarantees that DERs are rewarded for providing estimates that are both accurate and have a high confidence, ensuring that software agents are given credit for high probability estimates that are close to the realised ones.
Valentin adds: "Scoring rules with specific incentive properties have long been used to design payment mechanisms that incentivise agents to report private probabilistic predictions truthfully and to the best of their forecasting abilities.
"We show that our mechanism incentivises real DERs to form CVPPs, and outperforms the current state of the art payment mechanism developed for this problem."
The researchers collected half-hourly wind-speed data for a 10-week period from 16 commercial wind farms in the UK in order to validate their approach. They will be presenting their paper at the AAAI conference (22-26 July), in Toronto, Canada this week.
###
The Southampton researchers have been exploring these ideas for some time through the iDEaS project, an industrially-funded project, which aims to explore the issues associated with the decentralised control, operation and management of future generation electricity networks. The other members of the research team are Dr Ramachandra Kota and Dr Georgios Chalkiadakis. The project is led by Dr Alex Rogers and Professor Nick Jennings from Electronics and Computer Science at the University of Southampton. http://www.ideasproject.info/
