BP chief executive Tony Hayward canceled a scheduled appearance today at a London oil conference, citing his commitment to the Gulf relief effort.

Yet on the whole, the oil industry has been good to Lailhengue — very good. With a highschool degree, she pulls down white-collar money as a title analyst for a drilling company. That argument, echoed by Louisiana Gov. Bobby Jindal, the oil industry, and a multitude of regular Gulf-dwelling folk living close to the disaster, is at the heart of a lawsuit challenging the moratorium.

The plaintiffs, led by marine company Hornbeck Offshore Services LLC, argue that the government overstepped its bounds in issuing the May 28 moratorium that halted work on 33 deep-water rigs. District Judge Martin Feldman weighed those arguments as well as rebuttals from environmental groups. He is expected to decide whether to issue an injunction overturning the moratorium by Wednesday morning. About 40 workers are still underground, Antioquia state disaster coordinator John Rendon said Monday.

A fringe nationalist group, which calls the film anti-Japanese for criticizing what it calls a timehonored tradition, has staged rallies in and around Tokyo to press theaters to cancel screenings. Since the violent takeover of Gaza by Hamas — an Islamic militant group responsible for firing thousands of rockets at Israeli border communities — Israel has let in only limited humanitarian supplies, including basic foods and medicine.

Now that Israel is promising, under international pressure, to ease the restrictions, aid officials say urgent action is needed. During the three-year blockade, the U. Israel insists on maintaining its sea blockade and inspecting overland cargo to keep.

A Palestinian boy turns around last week as he walks toward a primary school housed inside United Nations Relief and Works Agency containers, in Nusseirat, central Gaza Strip. During a three-year Israeli blockade, the U. Israel remained vague Monday about how and when it expected to deliver more goods to Gaza.

Officials outlined procedures that suggested a slow pace, despite a White House call for quick changes in the blockade policy. Steps forward In coming days, Israel will review building projects with representatives of international organizations, including the U. Guy Inbar, a Defense Ministry official. If there are no security concerns, talks will begin on how much material is needed, he said. Such a procedure was in place during the blockade, but only one U.

The firm, ICP Asset Management, used the four CDOs, sold under the name Triaxx, like a piggy bank to enrich itself by diverting millions of dollars from investors, the commission said in the complaint. The Federal Reserve has completed an initial review of compensation policies at 28 large banks it oversees and has been giving them confidential feedback on areas where they must change.

On Monday, the Fed and other federal regulators issued final guidelines, stressing the need for policies that do not give executives, traders, and other bank employees incentives to make overly risky investments that might earn them huge bonuses in the short run while leaving the bank exposed to losses in the long term.

Two used bikes sat parked in a nearby rack. In the showroom, another stand held a nearly completed bike; frames hung from the wall, wheels and tires from the rafters, and a side room contained more bike frames and parts.

Bend Velo owner Eric Power, 49, plans to turn them all into custom bicycles. These bikes have fenders, fat tires, baskets, kickstands, new powder coating and cork hand grips wrapped with hemp. Power plans to outfit some with dynamo lighting systems. The bikes get dated with the year produced, and they even have a brand name: J.

The panelists said startup business owners should build a small board of advisers who have experience finding investors and building up companies. She said having advisers with recognizable names — such as angel investors, business owners or other business professionals — brings credibility to a business, and helps make investors more comfortable.

Paying to keep patients out of hospital Insurers taking the long view and investing in primary care with an eye toward prevention By Reed Abelson New York Times News Service. Like a lot of doctors, Patrick Kilduff has too many patients and too little time.

He and the five other physicians in Shavertown, Pa. That makes it virtually impossible to spend time explaining to patients the importance of keeping their blood sugar under control or how to take their medicine. They are giving primary care doctors more help — and more money — to take care of the sickest patients and help prevent them from becoming sicker.

Otherwise, insurers know they risk being overwhelmed by rising health care costs as an older, sicker population copes with serious chronic conditions. Glenn Steele Jr. Geisinger is known nationally for its innovative approaches to delivering high-quality care at lower cost.

They cautioned, though, that the rise in the currency, the renminbi, is expected to be gradual, even if many American economists say it is 20 percent to 40 percent undervalued. SGI, a California company that makes servers and data storage equipment, looks forward to extra business. In fact, costs have already been rising this year because of demands for higher wages among Chinese workers, who are balking at the coastal jobs once coveted as a way out of rural poverty.

That is because along with what it produces there, Caterpillar sells China some of its most sophisticated, and therefore expensive, American-made equipment, including giant bulldozers, large mining trucks and gas turbines.

John Frisbie, president of the United States-China Business Council, cited companies with low-end products, like apparel, shoes and toys, as among those most affected. Mitch Free, chairman of MFG. He expects the trend to continue. Fred Bergsten, director of the Peterson Institute for International Economics, predicted that if the renminbi rose by 20 percent over the next two.

Trade experts say that companies that export to China, such as Caterpillar, will benefit, and discounters that rely on China as a low-cost export platform may be squeezed. Frisbie was more skeptical about the impact on the trade deficit.

Neither a stronger renminbi nor higher wages would have much effect on major companies like GE or Boeing that have made large investments in China to sell to local consumers, he said.

An opportunity For companies that make products in China for sale elsewhere, however, there will be an incentive to reconsider where their factories are. Still, some companies may decide to continue diversifying their suppliers, said Hana BenShabat, who oversees A.

Cliff Kushler developed Swype, software that allows users to glide a finger across the virtual keyboard to spell words, rather than tapping out each letter. The introduction of Apple Inc. Capitalization and double letters can be indicated with a pause or squiggle, while spacing and punctuation are automatic.

That was before inventor Cliff Kushler, based here in Seattle, and a partner created software called T9, which could bring that number down to three by guessing the word being typed.

Now there is a new challenge to typing on phones. More phones are using virtual keyboards on a touch screen, replacing physical buttons. But pecking out a message on a small piece of glass is not so easy, and typos are common. Kushler thinks he has a solution once again.

His new technology, called Swype, allows users to glide a finger across the virtual keyboard to spell words, rather than tapping out each letter. Kushler developed Swype with a fellow research scientist, Randy Marsden. While many smart phones have features that auto-complete words, correct typos on the fly and add punctuation, Kushler is aiming for the next level.

Huge potential Kushler says Swype is a big breakthrough that could reach billions of people. To date, the T9 technology has been built into more than 4 billion devices worldwide.

The movements do not have to be precise because the software calculates which words a user is most likely trying to spell. By the end of the year, the company says its software will be on more than 50 models worldwide. It does not have a deal with Apple, the king of touch-screen phones, but it is tinkering with software for the iPhone and the iPad and hopes to show it to Apple soon.

To make money, Swype charges phone makers a licensing fee. It also sees opportunity in add-ons. Using Graffiti was slower than typing and forced people to learn an entirely new handwriting format to produce accurate results, said Gavin Lew, co-founder of User Centric, a consulting firm that studies user experiences with mobile devices.

He took note of the popularity of devices like those from Palm that used a. He worked with Marsden to fine-tune the Swype software — which took a laborious seven years. The competition Swype is not the only start-up hoping to profit from innovations in this area. Many companies are trying to improve the way people type on touch screens, which are proliferating swiftly. The research firm Gartner expects global sales of touch-screen devices to reach SlideIT, a start-up with offices in the United States and Israel, sells applications for touch screen text input with a finger or stylus for Symbian, Windows Mobile and Android-based phones.

The company says that since February its software has been downloaded more than , times. Nuance, a company best known for speech recognition software, acquired a start-up called ShapeWriter that matches patterns traced onto a touchscreen keyboard with those of commonly written words. It is negotiating with phone makers to use its software, called T9 Trace. Google is trying to let people skip the screen entirely by developing voice- and image-recognition technologies.

Its Goggles application can analyze a photo of some text and translate it into a different language — no typing required. Meanwhile, Swype is moving ahead with its own voice recognition feature, which it expects to add to smart phones this summer. New York Times News Service. Despite falling e-reader prices, the cost of electronic books has remained flat or actually risen slightly as publishers seek a bigger piece of the pie.

Amazon has said its main focus is on selling electronic books. The company even gives away software that allows customers to read e-books on personal computers, iPhones and BlackBerrys.

Later this year, Amazon reportedly will issue the next major update to the Kindle. The third version of the device is expected to be lighter than the current Noble reduced the price of its ereader, the Nook, by 23 percent.

But building bikes from recycled parts has been popular, he said. Customers like the idea of reusing old parts in a new bike, and those who do not keep up with the latest equipment or bike racing feel less intimidated at Bend Velo, he said.

Power agreed to answer some additional questions from The Bulletin. We have road bikes. Bend Velo also sells one line of new bikes, Bionicon mountain bikes, which have a unique on-the-fly air suspension system that allows them to morph from cross-country to downhill bike. On his website, Power calls Bio-. Why did you decide to start a bike shop? I worked in bike shops as a kid. I have been a bike racer. I embrace the whole racer scene. Where I thought Bend was lacking was in the needs of the practical cyclist.

We need a shop like this as an alternative. The doctors involved in the Geisinger experiment say they would not hesitate to hospitalize a patient if necessary. Many other insurers are also trying new, similar ways of rewarding primary care doctors. Continued from B1 Cox had gone to the emergency room with low blood sugar, but she has not been in the hospital for about three years. But she has no qualms about reaching out to the nurse. Under the arrangement with the outside doctors, Geisinger pays for the nurses and shares with the doctors any savings they can achieve by reducing medical expenses.

Geisinger says it is pleased with the early results. In an unpublished review of data, Geisinger experienced an 18 percent drop in hospital admissions; overall medical expenses fell 7 percent. Geisinger expects to publish a study on its results later this.

In one case, in Texas, a nurse whose salary is paid by Cigna discovered that a diabetic patient was missing checkups and not filling his prescriptions because he had lost his job. He was insured through his wife, but the couple could no longer afford to pay his share of the cost of prescriptions or the copayments for the office visit without his income. The nurse worked with the doctor to find cheaper medicines for the man and arranged for.

We need to get more people on bikes. To start riding your bike as basic transportation can truly be a life-changing experience. The shop really has a social cause as well because of the recycled parts becoming new bikes. The social aspect was unforeseen. What is different about your bikes?

But Ginsburg says insurers with many customers in a geographic market — like Blue Cross of Rhode Island, which covers two-thirds of those who are privately insured in the state — are also in a position to team with local doctors to provide better care.

But doctors say it is important. Geisinger offered InterMountain Medical at least half of any money saved from preventing readmissions to the hospital, among other measures. The reward was based, too, on various measures of the quality of care delivered. A model insurer? Even though such experiments seem promising, more evidence is needed to show that this model works, said Dr.

Jaan Sidorov, a former Geisinger insurance executive who is now a consultant. Others also worry that Geisinger, often cited as a national model for health care delivery, may be a tough act to follow. By investing heavily in technology, Geisinger has developed an unusually sophisticated way of tracking patients, and its own doctors — unlike many around the nation — have long made use of electronic health records.

Startups Continued from B1 Flynn credits her advisory board of about a half dozen people for those meetings, which she believes may turn into capital investment.

The type of company plays a large role in the kind of managers it needs, Putnam said. A company that is based around a brand, such as a specific clothing line, might want a person who knows marketing and another who knows how to manage people, while a biotech company might want a scientist, an Internet technician and a person who knows operations at the helm, she said. Management Companies also need to be able to grow at the right speed, Putnam said.

That means possibly holding off on hiring a slew of people when sales initially take off. One aspect that Putnam said often is overlooked is the chemistry of the management team. She said people in the management team must like one another. She said investors sometimes shy away from husband-wife teams without good reason. But now, with as many as three investors potentially interested in whippersnappers, she has her sights set on expansion: a goal of franchises nationwide within five years and new employees in Central Oregon in the next three to handle the growth.

For more information please stop by 10 NW Minnesota Avenue, call Attention, photographers! Submit your own photography at www. No doctored photos, please! From light comes shadows, the dark mirrors of reality. Including shadows in your images can add an extra dimension of visual interest. Some photo shoots have obvious shadow play, but at other times the photographer must search for locations and angles that allow him to capture and emphasize the shadows in the frame.

Viewers of your images will identify with the shadows in them. The viewer of a shadow sees a copy of the real scene. The vagueness of the information that the shadow reveals opens up the infinite possibilities for interpretation, giving the viewer a sort of fill-in-the-blank exercise for the brain. Because shadows create added interest and draw the viewer into. An opponent of the 3-cent gas tax in Sisters said Monday he will continue the legal fight to strike down the tax.

The controversy dates to August , when the Sisters City Council passed a 3-cent gas tax. The tax was referred to voters, who approved it during a March election. The city councils in Redmond and Madras also passed 3-cent gas taxes last year, but voters in both cities overwhelmingly rejected the proposed tax. That left Sisters alone in Central Oregon to defend the tax. Backed by the Oregon Petroleum Association, a gas dealer sued Sisters.

Once Romain and his clients file the appeal, the case could take more than a year to reach the court, Romain said. Romain plans to use the same argument as he did in Deschutes, that the March vote came too late for the tax to take effect. Romain also lost a case in Washington County, in which he argued the new 2-cent gas tax in Cornelius should be repealed.

Here are some tips for how to shoot them: In natural light, shoot in the morning or evening for the best chance at capturing large and detailed shadows. In the studio, lights allow for more direct manipulation of angle and intensity of the shadows you create. The shadows you create in the studio will draw you in as a photographer. Whether shooting in the studio or in natural light, big, clean backdrops work best when trying to create strong shadows. Experiment with natural and or studio lights to get shadow images you like, and let your imagination go wild.

Weather forces parkway crews to start later Bulletin staff reports Cold overnight weather conditions have affected construction work scheduled for the Bend Parkway, and will force crews to adjust work hours for later in the day this week, according to a news release from the Oregon Department of Transportation.

Construction crews applying wear-resistant materials on the Colorado Avenue and Burlington Northern Santa Fe railway overpasses will work from 5 a. Originally, the construction on the bridges was scheduled to be done between the hours of 3 a. However, due to freeze warnings and unusually chilly weather around Central Oregon during the past weeks, construction efforts are being rescheduled. Today, the southbound lanes of the Colorado overpass and the Burlington Northern Santa Fe overpass will undergo renovations.

Northbound lanes will be worked on during the second half of the week. Single lane closures in the work area are planned for the project. Signs will be posted to alert motorists to the construction. The monthlong project, which began June 7, is set to eliminate ruts and smooth out the surface of overpasses along the Bend Parkway by applying a wear-resistant surface to the road. The construction along the parkway is scheduled to be finished by July 1.

While out on the hunt for an interesting picture a few years back, I came across this BMX rider on a quarterpipe next to a youth center in Madras. I used flash to pop him with a bit of light. While shooting a few frames, I began to notice his shadow appearing on the wall beside him while he was airborne.

Playing in the shadow light, my son and I made this picture together during a recent warm evening. Shadows can bring out the child in all of us. Stretching out your arms to see your distorted shadows below can even make an old curmudgeon giggle. Using photography for fun times like this helps with your creative process. Let go a bit and allow the shadows to help direct your photography.

Charles Campbell, 79, of Bend, and his shadow were connected during a noxious weed cleanup in Bend. I turned my camera to focus on the shadow, making his actual body a small part of the image.

Instead , I zoomed in on his connection to the earth and his shadow emulating his movement. When starting out, turn your automatic flash function off.

If, after shooting for a while, you realize you need a bit of flash to light part of you image, try covering the flash with layers of tissue paper to soften the effect. Try using a wider-angle lens. A wider perspective will help the photographer get in close to the shadows to focus on the contrasting dark and light forms. This can be tricky, but shooting more images and continuing to change settings while taking notes throughout will allow you to eventually produce a shadow masterpiece. Former Warm Springs Chief Financial Officer Ray Potter said he was recently fired by the tribal government only days after speaking with federal investigators from the U.

Police said year-old Jocelyn Pabingwit was found by an officer behind a counter bleeding from stab wounds before her year-old husband, Diosdado Pabingwit, came at the officer with a bloody knife and was shot when he refused to drop it.

The couple lived in Hillsboro and owned JP Cuisine, the restaurant where the incident oc-. Police believe it was a case of domestic violence but are continuing to investigate. The federal grand jury indictment alleges Monticelli stole three Suzuki motorcycles that were property of the Department of Air Force, th Special Tactics Squadron, Oregon Air National Guard, where he was assigned on active duty.

Trial was set for Aug. District Court in Portland. Father and son responsible for wildfires dating back to , federal officials say By Jeff Barnard The Associated Press. The count federal indictment released Monday charges Dwight L.

Hammond Jr. Hammond, 41, with setting at least eight late-summer fires on federal lands on the flanks of Steens Mountain since Most fires were under acres, but one in , called the Granddad, was 46, acres. The Hammonds, who run a large cattle ranch, were not taken into custody. Arraignment was set for July 6 in U. District Court in Eugene on charges that include conspiracy, arson, depredation of federal property, threatening federal officers and tampering with a witness. The family ranch, on private and leased federal lands, is in the remote rural community of Diamond in Harney County, where cattle outnumber people and ranchers have long been at odds with conservationists over grazing on public lands.

The investigation started in August , after a U. Attorney Kirk Engdall said. The indictment mentions physical evidence that includes a boot print and a tire track from a military-style Jeep. The men were arrested in by local authorities but never formally charged, Engdall said.

Anyone that is potentially setting fires without first making preparations that the fires will be controlled puts everyone at risk. Our hope with the prosecution of this case is, one, to bring that to the attention of the general public, and two, to bring accountability for the alleged wrongful acts of the Hammonds.

The DOJ found,. Business people applying for new or renewed licenses often have their livelihoods at stake. That audit, by the way, was released just weeks before Bend officials sent a letter to Gov. New license applications took more than three times as long to process in Portland than they did in Bend and a whopping 20 times as long as in Salem. One application was still open after 18 months. After all, livelihoods were at stake. But, no. Managers had tools at their disposal to monitor the license process, according to the audit, but they simply chose not to use them.

Ignoring the applications-pending audit, however, was far from the only accountability problem in the Portland office. Another was simple absence of supervision. Why in the world would supervisors allow inspectors in a barely functional office to manage themselves? The auditor of the report asked.

This new grading system also makes it harder for employers to distinguish the wheat from the chaff, which means more students can get a shot at a competitive interview. Students and faculty say they are merely trying to stay competitive with their peer schools, which have more merciful grading curves.

Loyola, for example, had a mean first-year grade of 2. He also says many Loyola students are ineligible for coveted clerkships that have strict GPA cutoffs. The University of Southern California and the University of. California Hastings College of the Law responded by increasing their own curves last school year.

These moves can create a vicious cycle like that seen in chief executive pay: If every school in the bottom half of the distribution raises its marks to enter the top half of the distribution, or even just to become average, the average creeps up. This puts pressure on schools to keep raising their grades further. One notable school has managed to maintain the integrity of its grades through an idiosyncratic grading rubric.

The University of Chicago Law School grades its students on a scale of , a system so bizarre that employers are unlikely to try to match it against the 4. Last month, two Chinese immigrants spoke out publicly after being wrongly accused of shoplifting at the New York Supermarket, a store under the Manhattan Bridge in Chinatown that posts photographs of accused shoplifters next to the cashier, behind the live crabs and eels.

One of those immigrants, Li Yuxin, said that after being falsely accused of thievery, she began weeping in front of a crowd of shoppers. The other immigrant, Liang Huanqiong, a year-old home attendant, also said that false accusations of theft damaged her reputation and caused mental anguish. The episodes made headlines in Chinese-language newspapers, and store officials apologized to the women and said they would train employees to better recognize thievery and use more sensitivity in approaching suspected shoplifters, the articles reported.

Does it help? It is unclear whether grade inflation is particularly effective at helping students get jobs, especially because many large firms adjust their expectations accordingly. Many hiring partners say they read Above the Law, a legal. Both women are being advocated for by Wong, who is critical of the practices despite the apparent vagueness of the law. The police declined to discuss the legality of the practice because they had not investigated it.

Usually, the retailer threatens legal action and settles for a sum in the hundreds of dollars, experts in loss prevention said. This process is separate from criminal prosecution and can take place without arrest or conviction, and even if the case is criminally tried and thrown out. Richard Hollingera sociologist and criminologist at the University of Florida, said a shopkeeper demanding money on the spot was a version of the legal process of civil recovery outside the law.

He said it could veer into extortion, which New York law defines in partas demanding payment by making a person fear he will be accused of a crime or charged with one. Sanchez, the security guard, said some stores paraded the shoplifting suspect up and down the aisles, announcing the attempted theft to customers. Employers say they also press law schools for rankings, or some indication of GPAs for the top echelon of the class.

But he has noticed something else new from applicants. Poll finds multiple concerns on economy and energy By John M. Overwhelmingly, Americans think the nation needs a fundamental overhaul of its energy policies, and most Americans expect alternative forms of energy to replace oil as a major fuel source within 25 years.

Yet a majority are unwilling to pay higher gasoline prices to help develop new sources of energy. The survey included an indepth look at the attitudes of people most directly affected by the oil spill — those living in counties in Alabama, Louisiana and Mississippi that border the Gulf of Mexico.

Gulf Coast residents are more likely than other Americans to support increased drilling off the U. By a large margin, the public overall thinks more regulation of offshore drilling to protect the environment is needed, but they are also more likely to attribute the BP accident to a failure of the federal government to enforce existing rules than to a lack of adequate regulation. Two months after the rig explosion and fire, just 18 percent of Americans think that BP will be able to stop the leak in the next month.

There was finger-pointing over who was at fault. The cleanup, assumed to take just a few weeks, dragged on for months and was criticized for mistakes. Government officials and the oil company battled every step of the way. The oil company ended up pleading guilty to environmental crimes. Two decades later, the Gasconade seems to have recovered, due in part to lucky circumstances. But Wittler worries the Gulf will not turn out so well. The inch steel line, operated by a division of Shell Oil, carried crude miles from Oklahoma to a refinery in Wood River, Ill.

A long, thin crack dumped oil into the Shoal Creek tributary and then the Gasconade, a swift waterway that meanders north through 10 counties before emptying into the Missouri River. Louis, when the phone rang. The call was from a hog farmer living next to the Ozark property. He said the river was black. Oil smelled like it was hanging in the air. He suspected a pipeline had burst.

When Wittler drove up to the property two hours later, the fumes were so heavy he could barely breathe. Early confusion But Shell initially did not know the pipeline was spewing oil, according to a subsequent federal investigation. The delay made the spill four times worse, the report concluded.

Even more oil escaped because the pipeline valve nearest the leak could not be closed automatically. It had to be turned by hand. Shell eventually dispatched clean-up crews to Vienna that night. But the company was later criticized for failing to immediately notify state regulators. Meanwhile, the Gasconade was struggling to choke down a mile-long plume of oil, more than a foot thick in places.

Just as in the Gulf, floating boom lines were laid across the banks and ahead of the spill. And just as in the Gulf, there were reports of oil overtopping the booms. Vacuum-equipped trucks and a skimmer barge tried to suck oil from the water.

Within days, the plume thinned out into patches of tar balls, heavy chunks and a greasy sheen. The oil slid into the Mississippi River, reaching St. Louis within a week and then Cape Girardeau. Water treatment plants in the St. Louis area braced to deal with potential oil contamination. The AnheuserBusch brewery in St. Louis was shut down, and 2, workers were laid off for several days after a brewery taster noted an oily smell in the water.

Shell downplayed the severity. The long-term goal is a freestanding university that offers four years of instruction to be developed in 20 or more years. The creek is near a Shell Oil pipeline that ruptured on Christmas Eve. Workers clean oil sludge from the Gasconade River near its confluence with the Missouri River on Dec.

The men, employees of Riedel Environmental services of St. Louis, vacuumed the oil into tank trucks. But it did. At first, it said only , gallons of oil escaped. Then it would only comment on how much oil it recovered — about , gallons, estimating that accounted for 90 percent of the spill. The state Department of Natural Resources threatened a subpoena before Shell admitted the oil spill was at least , gallons, a number that would rise again.

Shell said it delayed reporting a figure only because it wanted to be accurate. Shell also tightly controlled the flow of information about the spill. Department of Justice environmental crimes prosecutor during the Gasconade spill. Shell blamed a pipe manufacturing defect for the spill.

The report noted that the lone Shell employee working Christmas Eve had not been trained to handle a crisis. Worse than first thought In early , after learning of problems with the clean-up, then-Gov. It kept adding workers until about people and 40 boats were deployed to scrub oil from miles of the Gasconade and parts of the Missouri River. According to Johnson, a committee is being formed to create a first-year experience for students entering OSU-Cascades and give a four-year experience feel to the Bend campus.

Sheila G. Miller can be reached at or at smiller bendbulletin. Then, state investigators found a hidden pool of oil on a sandbar that was supposedly clean. Someone else turned up several pairs of coveralls buried in the river by clean-up workers. The mood changed. Support for Shell withered. Two state officials had been monitoring the cleanup process. That number was beefed up to Shell said it would be done by April. Then more oil was discovered sitting in backwater channels. He was there to plead guilty on behalf of the company to a misdemeanor violation of dumping refuse into a waterway.

Shell and Texaco Pipeline Inc. But its former top executive, Robert McMahan, once offered advice to others in the oil business based on his experience with the Gasconade spill. Environmental problems can take many years and much effort to resolve.

It is better in the long run to prevent them from occurring in the first place. He would step onto a sandbar, and the water would develop an oily sheen.

Only in the last few years has that sheen disappeared, he said. The incident also was quickly overshadowed. Just three months after the Ozarks oil spill, the Exxon Valdez supertanker crashed in Alaska.

Local Service. Local Knowledge. Kenneth Feinberg, who has been tapped by the White House to run the fund, said many people are in desperate financial straits and need immediate relief. The rig was owned by Transocean Ltd. BP chief executive Tony Hayward canceled a scheduled appearance today at a London oil conference, citing his commitment to the Gulf relief effort.

Yet on the whole, the oil industry has been good to Lailhengue — very good. With a highschool degree, she pulls down white-collar money as a title analyst for a drilling company. That argument, echoed by Louisiana Gov. Bobby Jindal, the oil industry, and a multitude of regular Gulf-dwelling folk living close to the disaster, is at the heart of a lawsuit challenging the moratorium. The plaintiffs, led by marine company Hornbeck Offshore Services LLC, argue that the government overstepped its bounds in issuing the May 28 moratorium that halted work on 33 deep-water rigs.

District Judge Martin Feldman weighed those arguments as well as rebuttals from environmental groups. He is expected to decide whether to issue an injunction overturning the moratorium by Wednesday morning.

About 40 workers are still underground, Antioquia state disaster coordinator John Rendon said Monday. Officials hold out little hope any are still alive. Rescuers carried out 13 bodies Sunday from deep inside the 1. They found two more Monday. The blast occurred Wednesday. Rendon said debris and the persistent buildup of methane and carbon monoxide gases continue to impede rescue efforts.

A fringe nationalist group, which calls the film anti-Japanese for criticizing what it calls a timehonored tradition, has staged rallies in and around Tokyo to press theaters to cancel screenings. Since the violent takeover of Gaza by Hamas — an Islamic militant group responsible for firing thousands of rockets at Israeli border communities — Israel has let in only limited humanitarian supplies, including basic foods and medicine. Now that Israel is promising, under international pressure, to ease the restrictions, aid officials say urgent action is needed.

During the three-year blockade, the U. Israel insists on maintaining its sea blockade and inspecting overland cargo to keep. A Palestinian boy turns around last week as he walks toward a primary school housed inside United Nations Relief and Works Agency containers, in Nusseirat, central Gaza Strip.

But many questions remain unanswered, including whether Israel will allow full trade, seen as key to reviving industry and creating jobs.

Israel currently operates only one land crossing, but the government said it will open others if needed and if security concerns are addressed. In the Nusseirat refugee camp, the U.

A sandy lot serves as a playground. Mothers who calm their children by blowing opium smoke in their faces. Whole communities hooked on heroin with few opportunities for recovery treatment. Use of opiates such as heroin and opium has doubled in Afghanistan in the last five years, the U. Nearly 3 percent of Afghans ages 15 to 64 are addicted to opiates, according to a study by the U.

Some of the drop is likely due to lower market prices, but the government has said it also shows that the Afghan war on drugs is having some success. Yet almost 1 million Afghans — 8 percent of the to age group — are regular drug users, addicted to opiates, cannabis and tranquilizers, according to the report, which was based on surveys of about 2, drug users, community leaders, teachers and doctors.

The firm, ICP Asset Management, used the four CDOs, sold under the name Triaxx, like a piggy bank to enrich itself by diverting millions of dollars from investors, the commission said in the complaint. The Federal Reserve has completed an initial review of compensation policies at 28 large banks it oversees and has been giving them confidential feedback on areas where they must change. On Monday, the Fed and other federal regulators issued final guidelines, stressing the need for policies that do not give executives, traders, and other bank employees incentives to make overly risky investments that might earn them huge bonuses in the short run while leaving the bank exposed to losses in the long term.

Foreclosure-aid plan struggles In March , the Obama administration began a foreclosure-prevention program. Since then, about , borrowers have dropped out. Loan modifications under the housing plan, to date thousand Permanent modifications In front of the shop on Northeast Second Street, a repair stand held a bike frame.

Two used bikes sat parked in a nearby rack. In the showroom, another stand held a nearly completed bike; frames hung from the wall, wheels and tires from the rafters, and a side room contained more bike frames and parts.

Bend Velo owner Eric Power, 49, plans to turn them all into custom bicycles. These bikes have fenders, fat tires, baskets, kickstands, new powder coating and cork hand grips wrapped with hemp. Power plans to outfit some with dynamo lighting systems. The bikes get dated with the year produced, and they even have a brand name: J.

Livingston bicycles look like models from the s, or something a professor might be seen riding around a college campus.

To emphasize the classic look, Power used a typewriter font for the Livingston logo, which also has an abstract im-. One person may be all it takes to start a business, but owners looking to grow need well-versed advisers and a strong executive management team.

The panelists said startup business owners should build a small board of advisers who have experience finding investors and building up companies. She said having advisers with recognizable names — such as angel investors, business owners or other business professionals — brings credibility to a business, and helps make investors more comfortable. That seems to be working for Lisa Flynn and whippersnappers studio, a Bend photo studio with four franchises in three states. Flynn had three meetings earlier this month with venture capitalists and angel investors in San Francisco who are interested in buying into her business.

Second St. Bend has plenty of shops that sell bicycles, Power said, but many cater specifically to high-performance road riders or mountain bikers. Bend Velo makes bikes for the masses from recycled parts. Power, who wants to be like the town butcher or cobbler once found in nearly every city, wants to get people out of their cars and onto bicycles.

Paying to keep patients out of hospital Insurers taking the long view and investing in primary care with an eye toward prevention By Reed Abelson New York Times News Service. Like a lot of doctors, Patrick Kilduff has too many patients and too little time. He and the five other physicians in Shavertown, Pa. That makes it virtually impossible to spend time explaining to patients the importance of keeping their blood sugar under control or how to take their medicine.

They are giving primary care doctors more help — and more money — to take care of the sickest patients and help prevent them from becoming sicker. Otherwise, insurers know they risk being overwhelmed by rising health care costs as an older, sicker population copes with serious chronic conditions. Glenn Steele Jr. Geisinger is known nationally for its innovative approaches to delivering high-quality care at lower cost. They cautioned, though, that the rise in the currency, the renminbi, is expected to be gradual, even if many American economists say it is 20 percent to 40 percent undervalued.

SGI, a California company that makes servers and data storage equipment, looks forward to extra business. In fact, costs have already been rising this year because of demands for higher wages among Chinese workers, who are balking at the coastal jobs once coveted as a way out of rural poverty.

The acquiescence of House Democrats, after modest changes to limit the scope and soften the impact, may set a pattern for the week ahead. The conference committee of members from both chambers appointed to develop a final version of the legislation must complete its work this week to maintain the schedule set by Democratic. Key remaining issues include how to regulate derivatives trading, the extent of restrictions on banks investing their own money, and whether to require stronger buffers against unexpected losses.

That is because along with what it produces there, Caterpillar sells China some of its most sophisticated, and therefore expensive, American-made equipment, including giant bulldozers, large mining trucks and gas turbines.

John Frisbie, president of the United States-China Business Council, cited companies with low-end products, like apparel, shoes and toys, as among those most affected.

Mitch Free, chairman of MFG. He expects the trend to continue. Fred Bergsten, director of the Peterson Institute for International Economics, predicted that if the renminbi rose by 20 percent over the next two. Trade experts say that companies that export to China, such as Caterpillar, will benefit, and discounters that rely on China as a low-cost export platform may be squeezed.

Frisbie was more skeptical about the impact on the trade deficit. Neither a stronger renminbi nor higher wages would have much effect on major companies like GE or Boeing that have made large investments in China to sell to local consumers, he said.

An opportunity For companies that make products in China for sale elsewhere, however, there will be an incentive to reconsider where their factories are. Still, some companies may decide to continue diversifying their suppliers, said Hana BenShabat, who oversees A.

She said she did not expect a wave of moves to lower-wage countries because labor costs make up only 15 percent to 20 percent of apparel costs.

Now you can visit www. Cliff Kushler developed Swype, software that allows users to glide a finger across the virtual keyboard to spell words, rather than tapping out each letter. The introduction of Apple Inc. Capitalization and double letters can be indicated with a pause or squiggle, while spacing and punctuation are automatic.

That was before inventor Cliff Kushler, based here in Seattle, and a partner created software called T9, which could bring that number down to three by guessing the word being typed. Now there is a new challenge to typing on phones.

More phones are using virtual keyboards on a touch screen, replacing physical buttons. But pecking out a message on a small piece of glass is not so easy, and typos are common.

Kushler thinks he has a solution once again. His new technology, called Swype, allows users to glide a finger across the virtual keyboard to spell words, rather than tapping out each letter. Kushler developed Swype with a fellow research scientist, Randy Marsden. While many smart phones have features that auto-complete words, correct typos on the fly and add punctuation, Kushler is aiming for the next level.

Huge potential Kushler says Swype is a big breakthrough that could reach billions of people. To date, the T9 technology has been built into more than 4 billion devices worldwide. The movements do not have to be precise because the software calculates which words a user is most likely trying to spell. By the end of the year, the company says its software will be on more than 50 models worldwide.

It does not have a deal with Apple, the king of touch-screen phones, but it is tinkering with software for the iPhone and the iPad and hopes to show it to Apple soon. To make money, Swype charges phone makers a licensing fee. It also sees opportunity in add-ons. Using Graffiti was slower than typing and forced people to learn an entirely new handwriting format to produce accurate results, said Gavin Lew, co-founder of User Centric, a consulting firm that studies user experiences with mobile devices.

He took note of the popularity of devices like those from Palm that used a. He worked with Marsden to fine-tune the Swype software — which took a laborious seven years. The competition Swype is not the only start-up hoping to profit from innovations in this area. Many companies are trying to improve the way people type on touch screens, which are proliferating swiftly.

The research firm Gartner expects global sales of touch-screen devices to reach SlideIT, a start-up with offices in the United States and Israel, sells applications for touch screen text input with a finger or stylus for Symbian, Windows Mobile and Android-based phones.

The company says that since February its software has been downloaded more than , times. Nuance, a company best known for speech recognition software, acquired a start-up called ShapeWriter that matches patterns traced onto a touchscreen keyboard with those of commonly written words. It is negotiating with phone makers to use its software, called T9 Trace.

Google is trying to let people skip the screen entirely by developing voice- and image-recognition technologies. Its Goggles application can analyze a photo of some text and translate it into a different language — no typing required. Meanwhile, Swype is moving ahead with its own voice recognition feature, which it expects to add to smart phones this summer.

New York Times News Service. Despite falling e-reader prices, the cost of electronic books has remained flat or actually risen slightly as publishers seek a bigger piece of the pie. Amazon has said its main focus is on selling electronic books. The company even gives away software that allows customers to read e-books on personal computers, iPhones and BlackBerrys. Later this year, Amazon reportedly will issue the next major update to the Kindle.

The third version of the device is expected to be lighter than the current Noble reduced the price of its ereader, the Nook, by 23 percent. Hours later Amazon responded with an even deeper price cut of 27 percent.

But building bikes from recycled parts has been popular, he said. Customers like the idea of reusing old parts in a new bike, and those who do not keep up with the latest equipment or bike racing feel less intimidated at Bend Velo, he said.

Power agreed to answer some additional questions from The Bulletin. We have road bikes. Bend Velo also sells one line of new bikes, Bionicon mountain bikes, which have a unique on-the-fly air suspension system that allows them to morph from cross-country to downhill bike.

On his website, Power calls Bio-. Why did you decide to start a bike shop? I worked in bike shops as a kid. I have been a bike racer. I embrace the whole racer scene. Where I thought Bend was lacking was in the needs of the practical cyclist. We need a shop like this as an alternative. The doctors involved in the Geisinger experiment say they would not hesitate to hospitalize a patient if necessary.

Many other insurers are also trying new, similar ways of rewarding primary care doctors. Continued from B1 Cox had gone to the emergency room with low blood sugar, but she has not been in the hospital for about three years. But she has no qualms about reaching out to the nurse.

Under the arrangement with the outside doctors, Geisinger pays for the nurses and shares with the doctors any savings they can achieve by reducing medical expenses. Geisinger says it is pleased with the early results. In an unpublished review of data, Geisinger experienced an 18 percent drop in hospital admissions; overall medical expenses fell 7 percent.

Geisinger expects to publish a study on its results later this. In one case, in Texas, a nurse whose salary is paid by Cigna discovered that a diabetic patient was missing checkups and not filling his prescriptions because he had lost his job. He was insured through his wife, but the couple could no longer afford to pay his share of the cost of prescriptions or the copayments for the office visit without his income. The nurse worked with the doctor to find cheaper medicines for the man and arranged for.

We need to get more people on bikes. To start riding your bike as basic transportation can truly be a life-changing experience. The shop really has a social cause as well because of the recycled parts becoming new bikes.

The social aspect was unforeseen. What is different about your bikes? People can build the bikes, pick the color bike, pick matching fenders. How do you see the business evolving? Riders get on their Livingstons, Raleigh three-speeds.

The men look like Sherlock Holmes. The women look like Dutch ladies on bikes. My dream is that when I go to the farmers market in Bend, I see people who have ridden there on J.

Livingston bikes to buy their produce. Why did you name the bikes after your friend John Livingston? I went to work thinking of the J. Livingston design. My friends and I got together and compared ideas. Has starting this business led to anything.

But Ginsburg says insurers with many customers in a geographic market — like Blue Cross of Rhode Island, which covers two-thirds of those who are privately insured in the state — are also in a position to team with local doctors to provide better care. But doctors say it is important. Geisinger offered InterMountain Medical at least half of any money saved from preventing readmissions to the hospital, among other measures.

The reward was based, too, on various measures of the quality of care delivered. A model insurer? Even though such experiments seem promising, more evidence is needed to show that this model works, said Dr. Jaan Sidorov, a former Geisinger insurance executive who is now a consultant. Others also worry that Geisinger, often cited as a national model for health care delivery, may be a tough act to follow. By investing heavily in technology, Geisinger has developed an unusually sophisticated way of tracking patients, and its own doctors — unlike many around the nation — have long made use of electronic health records.

Startups Continued from B1 Flynn credits her advisory board of about a half dozen people for those meetings, which she believes may turn into capital investment. The type of company plays a large role in the kind of managers it needs, Putnam said.

A company that is based around a brand, such as a specific clothing line, might want a person who knows marketing and another who knows how to manage people, while a biotech company might want a scientist, an Internet technician and a person who knows operations at the helm, she said.

Management Companies also need to be able to grow at the right speed, Putnam said. That means possibly holding off on hiring a slew of people when sales initially take off. One aspect that Putnam said often is overlooked is the chemistry of the management team. She said people in the management team must like one another. She said investors sometimes shy away from husband-wife teams without good reason.

But now, with as many as three investors potentially interested in whippersnappers, she has her sights set on expansion: a goal of franchises nationwide within five years and new employees in Central Oregon in the next three to handle the growth.

Due diligence Jon Napier, an attorney at Karnopp Petersen, said business owners should always keep track of documents, both for investors and for hiring executives.

For more information please stop by 10 NW Minnesota Avenue, call Attention, photographers! Submit your own photography at www.

No doctored photos, please! From light comes shadows, the dark mirrors of reality. Including shadows in your images can add an extra dimension of visual interest.

Some photo shoots have obvious shadow play, but at other times the photographer must search for locations and angles that allow him to capture and emphasize the shadows in the frame. Viewers of your images will identify with the shadows in them. The viewer of a shadow sees a copy of the real scene. The vagueness of the information that the shadow reveals opens up the infinite possibilities for interpretation, giving the viewer a sort of fill-in-the-blank exercise for the brain.

Because shadows create added interest and draw the viewer into. An opponent of the 3-cent gas tax in Sisters said Monday he will continue the legal fight to strike down the tax. The controversy dates to August , when the Sisters City Council passed a 3-cent gas tax. The tax was referred to voters, who approved it during a March election. The city councils in Redmond and Madras also passed 3-cent gas taxes last year, but voters in both cities overwhelmingly rejected the proposed tax.

That left Sisters alone in Central Oregon to defend the tax. Backed by the Oregon Petroleum Association, a gas dealer sued Sisters. Once Romain and his clients file the appeal, the case could take more than a year to reach the court, Romain said. Romain plans to use the same argument as he did in Deschutes, that the March vote came too late for the tax to take effect. Romain also lost a case in Washington County, in which he argued the new 2-cent gas tax in Cornelius should be repealed.

Here are some tips for how to shoot them: In natural light, shoot in the morning or evening for the best chance at capturing large and detailed shadows. In the studio, lights allow for more direct manipulation of angle and intensity of the shadows you create. The shadows you create in the studio will draw you in as a photographer. Whether shooting in the studio or in natural light, big, clean backdrops work best when trying to create strong shadows.

Experiment with natural and or studio lights to get shadow images you like, and let your imagination go wild. I shot it while we were hiking up a trail behind the lodge to capture the mountain sunset in the background of my wedding photos. This image works on a couple of levels: The pathway frames the bride and groom, and the greenery adds interesting points around them. Photos by Andy Tullis. Weather forces parkway crews to start later Bulletin staff reports Cold overnight weather conditions have affected construction work scheduled for the Bend Parkway, and will force crews to adjust work hours for later in the day this week, according to a news release from the Oregon Department of Transportation.

Construction crews applying wear-resistant materials on the Colorado Avenue and Burlington Northern Santa Fe railway overpasses will work from 5 a. Originally, the construction on the bridges was scheduled to be done between the hours of 3 a. However, due to freeze warnings and unusually chilly weather around Central Oregon during the past weeks, construction efforts are being rescheduled.

Today, the southbound lanes of the Colorado overpass and the Burlington Northern Santa Fe overpass will undergo renovations. Northbound lanes will be worked on during the second half of the week. Single lane closures in the work area are planned for the project.

Signs will be posted to alert motorists to the construction. The monthlong project, which began June 7, is set to eliminate ruts and smooth out the surface of overpasses along the Bend Parkway by applying a wear-resistant surface to the road. The construction along the parkway is scheduled to be finished by July 1. While out on the hunt for an interesting picture a few years back, I came across this BMX rider on a quarterpipe next to a youth center in Madras.

I used flash to pop him with a bit of light. While shooting a few frames, I began to notice his shadow appearing on the wall beside him while he was airborne. Playing in the shadow light, my son and I made this picture together during a recent warm evening. Shadows can bring out the child in all of us. Stretching out your arms to see your distorted shadows below can even make an old curmudgeon giggle. Using photography for fun times like this helps with your creative process. Let go a bit and allow the shadows to help direct your photography.

Charles Campbell, 79, of Bend, and his shadow were connected during a noxious weed cleanup in Bend. I turned my camera to focus on the shadow, making his actual body a small part of the image. Instead , I zoomed in on his connection to the earth and his shadow emulating his movement. When starting out, turn your automatic flash function off. If, after shooting for a while, you realize you need a bit of flash to light part of you image, try covering the flash with layers of tissue paper to soften the effect.

Try using a wider-angle lens. A wider perspective will help the photographer get in close to the shadows to focus on the contrasting dark and light forms. This can be tricky, but shooting more images and continuing to change settings while taking notes throughout will allow you to eventually produce a shadow masterpiece. Former Warm Springs Chief Financial Officer Ray Potter said he was recently fired by the tribal government only days after speaking with federal investigators from the U.
