States increasingly raising transportation taxes

Written By Unknown on Senin, 04 Agustus 2014 | 20.25

JEFFERSON CITY, Mo. — States are taking it upon themselves to raise revenues for roads and mass transit as federal lawmakers remain stymied on long-term highway funding.

An Associated Press review found that one-fourth of the states have enacted transportation funding increases in the past year and a half, and at least a dozen others are studying it.

Missouri voters will decide Tuesday whether to impose a three-quarters cent sales tax for transportation.

The push for more funding comes as revenues from federal and state fuel taxes are deteriorating because of more fuel efficient cars, a decline in per capita driving and stagnant tax rates.

Congress recently approved a 10-month patch for its highway trust fund but still has not addressed a long-term transportation funding plan.

LG headphones get job done, but at hefty cost

LG Heart Rate Monitor Earphones (Best Buy, $179.99)

LG has started an entirely new product category by deciding to stick heart rate sensors into something you're already likely wearing while you're working out. These double-duty headphones are Bluetooth-enabled and connect to an accompanying LG fitness app for iOS and Android. A blood-flow sensor hides directly in the right earbud.

The good: These earbuds are as comfortable as any you'll find, and you don't need to stay tethered to your smartphone or iPod to listen to music. What's more, they seem to be accurate.

The bad: The high price is hard to justify with less-than-stellar sound quality. And while these earbuds are hands-free, they're not exactly wireless, with a controller that needs to be clipped to whatever clothing you're wearing.

The bottom line: A wearable product that actually works! Cool.

NIH's Fauci says vaccine for Ebola not far away

WASHINGTON — The nation's top infectious disease official says there's hope that a vaccine against Ebola will be available as early as next July.

Dr. Anthony Fauci (FOW'-chee) of the National Institutes of Health says such a preventive vaccine has been successfully tested with monkeys.

Fauci tells "CBS This Morning" that human trials with volunteers will commence in September, and by July it should be ready.

He also says people shouldn't have concerns that two infected patients were brought here from West Africa, saying they can be handled safely.

More than 1,300 people have been stricken in West Africa, and nearly 730 have died in Guinea, Liberia and Sierre Leone.

Ebola currently has no vaccine or antidote. It is contracted through close contact with bodily fluid and blood, unlike other airborne viruses.

Wal-Mart's website to personalize shopping

NEW YORK — Wal-Mart, in its latest bid to compete with nemesis Amazon.com, is rebuilding its website to further personalize the online shopping experience of each customer.

Wal-Mart is rolling out a feature that will enable its website to show shoppers more products that they may like, based on previous purchases. It will also customize Wal-Mart's home page for each shopper based on the customer's location, local weather and the customer's search and purchase history.

So if a new mom just bought a stroller or crib on Walmart.com, the revamped website might recommend diapers and car seats, too. And if someone who lives in Dallas searches the website for sports jerseys, Walmart.com could suggest Rangers or Dallas Cowboy gear.

The increased personalization is part of a series of changes to improve the online shopping experience of its customers that are rolling out now and over the next few months. The retailer is looking to boost its business online at a time when its U.S. discount division has seen disappointing sales.

Wal-Mart Stores Inc.'s e-commerce sales increased by 30 percent to over $10 billion in its fiscal year that ended Jan. 31. By comparison, Wal-Mart's U.S. discount division has had five straight quarters of sales declines at stores opened at least a year. Wal-Mart sees big growth opportunity in the online business: Online sales still are only a fraction of the $473 billion Wal-Mart generated in overall annual revenue, dwarfed by Amazon's $60.9 billion in annual sales.

The move to personalize websites for shoppers has become a top priority for traditional brick-and-mortar retailers like Wal-Mart as they play catch up with Amazon.com, the online king that pioneered customizing content for shoppers. Retailers increasingly are trying to use their reams of customer data they get from mobile devices and computers to personalize their websites and ultimately, boost sales.

Other retailers, including home-improvement chain Home Depot and office-supplies retailer Staples, have been working to personalize the online shopping experience. In fact, a quarter of customers who visit Home Depot's home page see product recommendations that are based on recent purchase or browser history, according to the company.

Retailers have seen benefits in personalizing their websites for customers, as well as other efforts to improve the online shopping experience. Overall, Forrester Research analyst Sucharita Mulpuru said that changes in customization can help lift a retailer's online sales in the mid-single digits.

Wal-Mart said that customers have responded well to improvements it has made to its website in the past two years, including quadrupling the assortment of items it offers online to 8 million. For example, when Wal-Mart updated its search tool, it saw a 20 percent increase in shoppers completing a purchase after searching for a product using the new search engine.

Among the other changes, Wal-Mart has redesigned the site to cater to tablets as well as other devices. That means that the content and images are now adjusted to the size of the screen. So shoppers will see more columns of products on bigger screens.

Shoppers will see other improvements. Walmart.com will be testing a quicker online checkout process over the next couple of months. That means customers will view one page instead of six before clicking on the "buy" button. And the company will be able to update Web pages within minutes instead of days.

Stocks recover some ground but questions remain

LONDON — Global stock markets recovered some recent lost ground Monday in the wake of last week's U.S. jobs data. However, questions over whether the recent sell-off in markets, which saw the Dow Jones industrial average in the U.S. slip into negative territory for the year, was over.

KEEPING SCORE: In early afternoon trading, France's CAC-40 rose 0.8 percent to 4,236 while Germany's DAX rose 0.2 percent to 9,230. Britain's FTSE 100 rose 0.5 percent to 6,711. Futures suggested a solid Wall Street rebound — Dow futures were up 0.3 percent while the broader S&P 500 futures rose by the same rate too.

ANALYST TAKE: "Despite this slightly positive start to the week, there does appear to be a little caution in the markets," said Alpari analyst Craig Erlam. "Investors are a little concerned that the sell-off which started last week is not over and could lead to something much bigger."

US JOBS: Last Friday's U.S. employment data helped calm the mood in markets. The figures showed the U.S. generated more than 200,000 jobs for a sixth straight month. At the same time, most economists don't think the pace of job growth is enough to cause the Federal Reserve to speed up its timetable for raising interest rates. Most still think the Fed will start raising rates to ward off inflation around mid-2015.

PORTUGESE BANK BAILOUT: In Europe, the main piece of news was the announcement by Portugal's central bank late Sunday that it will provide 4.9 billion euros ($6.6 billion) in an emergency rescue to prevent the collapse of ailing bank Banco Espirito Santo, one of the country's biggest financial institutions.

ASIA'S DAY: China's Shanghai Composite Index jumped 1.7 percent and Hong Kong's Hang Seng gained 0.3 percent. South Korea's Kospi added 0.4 percent but Tokyo's Nikkei 225 ended down 0.3 percent at 15,474.50.

CURRENCIES, OIL: The currency markets were flat from last Friday's close, with the dollar steady at 102.57 yen and the euro flat at $1.3424. Benchmark U.S. crude for September delivery was down 31 cents at $97.57 per barrel.

Cool idea for saving produce

Written By Unknown on Minggu, 03 Agustus 2014 | 20.26

A MassChallenge finalist is developing mobile refrigeration units that run on sun and water and are capable of saving the nearly one-half of developing-world produce that spoils before it ever reaches the consumer.

Evaptainers was the brainchild of Quang 
Truong, who was taking a class at MIT called "Development Ventures" last year, when his professor posed a challenge to the class: Think of a major problem in the developing world, and then come up with a solution.

"I've been to many developing countries over the years, and the one thing I've always noticed was how much produce spoiled," said Truong, a 27-year-old graduate of the Tufts Fletcher School, where he studied agriculture. "It's a huge problem a lot of agencies and governments are trying to deal with."

In his travels, he also had come across a "cool" invention, developed by a Nigerian, called the Pot-in-Pot Preservation Cooling System, essentially a small earthenware pot within a larger one, separated by a layer of wet sand.

The inner pot is filled with produce and covered with a wet cloth. And as the water in the sand and cloth evaporates, the temperature of the inner pot drops by as much as 40 degrees.

For farmers trying to get their produce to market, however, it had one important drawback, Truong said: The pots break easily, making them impractical to transport.

"I thought, hey, there's this really simple invention," he said. "Can I just make it mobile?"

Truong teamed up with a friend, Spencer Taylor, and founded Evaptainers, combining the time-tested evaporative cooling technique of the pot-in-pot system with modern design and materials.

In place of earthenware pots, Evaptainers are made of a breathable crate with wheels on one end and a storage container nestled inside. Between the crate and the container is an evaporative medium such as jute, sawdust or ceramic beads, supplied with water from a tank in the lid. When water evaporates from the medium into ambient air, latent heat is carried by evaporation into the surrounding environment, reducing the temperature inside the container to keep the produce cold.

Currently, Truong and Taylor are building their initial field test unit, which they hope to use in a three-month pilot in Morocco either late this year or early next year. If the pilot is successful, the two would sell Evaptainers for $80 to $120 to agricultural cooperatives there, allowing farmers to nearly double the amount of produce they could sell, with no more work, said Taylor, 32.

In the future, the co-founders said, Evaptainers also could be sold in the U.S. for use in farmers markets, farm shares and campsites.

5 things to know about Ebola outbreak in W. Africa

Three West Africa nations are struggling to control an outbreak of Ebola. The virus was first discovered nearly four decades ago in Congo in a village near the Ebola River. Since then there have been sporadic outbreaks.

Five things to know about Ebola and how it is spread:

1. WEST AFRICA OUTBREAK NOW LARGEST IN HISTORY. The current outbreak in the neighboring countries of Liberia, Guinea and Sierra Leone has sickened more than 1,300 people and killed more than 700 since March. The outbreak is unusual for West Africa as the disease is typically found in the center and east of the continent.

2. SOME PEOPLE HAVE SURVIVED EBOLA. While the fatality rate for Ebola can be as high as 90 percent, health officials in the three countries say people have recovered from the virus and the current death rate is about 60 percent. Those who fared best sought immediate medical attention and got supportive care to prevent dehydration even though there is no specific treatment for Ebola itself.

3. EBOLA CAN LOOK LIKE OTHER DISEASES. The early symptoms of an Ebola infection include fever, headache, muscle aches and sore throat. It can be difficult to distinguish between Ebola and malaria, typhoid fever or cholera. Only in later stages do people with Ebola begin bleeding both internally and externally, often through the nose and ears.

4. EBOLA IS ONLY SPREAD THROUGH CLOSE CONTACT. The Ebola virus is not airborne, so people would have to come into direct contact with the bodily fluids of an infected person. These include blood, sweat, vomit, feces, urine, saliva or semen — making transmission through casual contact in a public setting unlikely.

5. FEAR AND MISINFORMATION. In the three countries, health workers and clinics have come under attack from panicked residents who mistakenly blame foreign doctors and nurses for bringing the virus to remote communities. Family members also have removed sick Ebola patients from hospitals. Government officials have stepped up efforts to isolate patients, educate the public, check travelers and tighten borders to prevent the disease's spread.

US doctor with Ebola in Atlanta for treatment

ATLANTA — The first Ebola victim to be brought to the United States from Africa was safely escorted into a specialized isolation unit Saturday at one of the nation's best hospitals, where doctors said they are confident the deadly virus won't escape.

Fear that the outbreak killing more than 700 people in Africa could spread in the U.S. has generated considerable anxiety among some Americans. But infectious disease experts said the public faces zero risk as Emory University Hospital treats a critically ill missionary doctor and a charity worker who were infected in Liberia.

The U.S. Centers for Disease Control and Prevention has received "nasty emails" and at least 100 calls from people saying "How dare you bring Ebola into the country!?" CDC Director Dr. Tom Frieden told The Associated Press Saturday.

"I hope that our understandable fear of the unfamiliar does not trump our compassion when ill Americans return to the U.S. for care," Frieden said.

Dr. Kent Brantly and Nancy Writebol, who will arrive in several days, will be treated in Emory's isolation unit for infectious diseases, created 12 years ago to handle doctors who get sick at the CDC, just up the hill. It is one of about four in the country, equipped with everything necessary to test and treat people exposed to very dangerous viruses.

In 2005, it handled patients with SARS, which unlike Ebola can spread when an infected person coughs or sneezes.

In fact, the nature of Ebola — which is spread by close contact with bodily fluids and blood — means that any modern hospital using standard, rigorous, infection-control measures should be able to handle it.

Still, Emory won't be taking any chances.

"Nothing comes out of this unit until it is non-infectious," said Dr. Bruce Ribner, who will be treating the patients. "The bottom line is: We have an inordinate amount of safety associated with the care of this patient. And we do not believe that any health care worker, any other patient or any visitor to our facility is in any way at risk of acquiring this infection."

Brantly was flown from Africa to Dobbins Air Reserve base outside Atlanta in a small plane equipped to contain infectious diseases, and a small police escort followed his ambulance to the hospital. He climbed out dressed head to toe in white protective clothing, and another person in an identical hazardous materials suit held both of his gloved hands as they walked gingerly inside.

"It was a relief to welcome Kent home today. I spoke with him, and he is glad to be back in the U.S.," said his wife, Amber Brantly, who left Africa with their two young children for a wedding in the U.S. days before the doctor fell ill.

"I am thankful to God for his safe transport and for giving him the strength to walk into the hospital," her statement said.

Inside the unit, patients are sealed off from anyone who doesn't wear protective gear.

"Negative air pressure" means air flows in, but can't escape until filters scrub any germs from patients. All laboratory testing is conducted within the unit, and workers are highly trained in infection control. Glass walls enable staff outside to safely observe patients, and there's a vestibule where workers suit up before entering. Any gear is safely disposed of or decontaminated.

Family members will be kept outside for now.

The unit "has a plate glass window and communication system, so they'll be as close as 1-2 inches from each other," Ribner said.

Dr. Jay Varkey, an infectious disease specialist who will be treating Brantly and Writebol, gave no word Saturday about their condition. Both were described as critically ill after treating Ebola patients at a missionary hospital in Liberia, one of four West African countries hit by the largest outbreak of the virus in history.

There is no proven cure for the virus. It kills an estimated 60 percent to 80 percent of the people it infects, but American doctors in Africa say the mortality rate would be much lower in a functioning health care system.

The virus causes hemorrhagic fever, headaches and weakness that can escalate to vomiting, diarrhea and kidney and liver problems. Some patients bleed internally and externally.

There are experimental treatments, but Brantly had only enough for one person, and insisted that his colleague receive it. His best hope in Africa was the transfusion of blood he received including antibodies from one of his patients, a 14-year-old boy who survived thanks to the doctor.

There was also only room on the plane for one patient at a time. Writebol will follow in several days.

Dr. Philip Brachman, an Emory public health specialist who led the CDC's disease detectives program for many years, said Friday that since there is no cure, medical workers will try any modern therapy that can be done, such as better monitoring of fluids, electrolytes and vital signs.

"We depend on the body's defenses to control the virus," Dr. Ribner said. "We just have to keep the patient alive long enough in order for the body to control this infection."

Just down the street from the hospital, people dined, shopped and carried on with their lives Saturday. Several interviewed by the AP said the patients are coming to the right place.

"We've got the best facilities in the world to deal with this stuff," said Kevin Whalen, who lives in Decatur, Ga., and has no connection to Emory or the CDC. "With the resources we can throw at it, it's the best chance this guy has for survival. And it's probably also the best chance to develop treatments and cures and stuff that we can take back overseas so that it doesn't come back here."

Explorer̢۪s odd symptoms point to torque converter

My 2000 Ford Explorer 4-liter Control-Trac 4WD has 120,000 miles on it. At 84,000 miles the O/D (overdrive) light began flashing randomly. The shop identified fault code P0741, indicating a potential issue with the transmission. I chose to keep driving the vehicle and the transmission has not failed yet, but I've noticed something peculiar. The light will begin flashing at specific locations on the routes I commonly take, and always where there is a power line overhead. It is also directional. The light will flash, for example, if I'm headed north but not if I'm headed south on the same road. Is there a sensor that could be sensitive to temperature and magnetic flux? Is the transmission failing?

Magnetic flux? Interesting thought, but highly unlikely. (I did have an early computerized fuel-injected vehicle — a beautiful '77 Cadillac Seville — that could be turned off by keying the microphone on a nearby handheld walkie-talkie. Took a while to figure what was shutting down the car as I drove out to a corner of the racetrack to observe my Skip Barber students! Apparently, the RF signal from the radio was interfering with the PCM and shutting down the engine.)

But as much as I'd like to believe that "magnetic flux" could be the culprit, the fact that the event only seems to trigger the O/D warning light rather than affecting any or all of the other computerized systems in your vehicle points to some more earthbound cause.

The P0174 code is triggered when the PCM detects excessive torque converter clutch (TCC) slippage under normal driving. Have you noticed whether the light comes on as you are driving slightly uphill? The extra load on the drivetrain may generate excess slippage in this location, but of course driving in the opposite direction on the same piece of road would be downhill, far less likely to generate TCC slippage.

TCC slippage does not mean impending transmission failure, but it does mean the TCC is worn, the transmission fluid is significantly contaminated and/or hydraulic pressure is somewhat low.

At the current mileage my suggestion is to add half a can of SeaFoam Trans-Tune to the transmission fluid and hope this reduces the symptoms, and continue to drive the vehicle until something catastrophic happens — then decide whether to repair or replace the vehicle.

I recently purchased and am restoring a 1971 Volvo 1800E. This car is fuel-injected. Do you believe it is necessary to use a lead alternative additive until the day I need a valve job and can add hardened valve seats? Should I try to purchase non-oxygenated gasoline?

This is an older question I "rediscovered" recently, but since it's the heart of the summertime collector-car driving season, I thought it worth answering — sorry for the delay.

To my knowledge, most carmakers were installing hardened valve seats by about 1970, so I don't think you need to be particularly concerned about excess wear unless you are really "leaning" on the engine — full throttle, high RPM — regularly.

Most so-called lead substitutes are not actually tetra-ethyl lead, which is no longer permitted in highway-use motor fuels, they are similar "metallics" that hopefully perform the same cooling and lubricating functions to prevent valve seat overheating, sinking and erosion.

I do, on the other hand, believe you should seek out, purchase and use non-oxy fuel for your older vehicle to protect fuel system components from contamination and corrosion. These parts, including the fuel tank and fuel lines, were not designed for oxygenated fuels.

Massachusetts big on farm-fresh goods

Massachusetts has the sixth-largest number of farmers markets in the nation, as farmers turn to new venues to supplement their incomes and consumers seek out ways to buy fresh, local food, according to the U.S. Department of Agriculture's newly updated National Farmers Market Directory.

Over the past year alone, the number of farmers markets in the state has risen 5.9 percent to 306, just behind California, New York, Michigan, Ohio and Illinois, Anne Alonzo, administrator of the USDA's Agricultural Marketing Service, said as she kicked off National Farmers Market Week.

"The growth of farmers markets and the buy-local movement is a reflection of citizens wanting to know where their food comes from, who grew it and how, combined with a genuine interest in supporting local agriculture," said Greg Watson, state Department of Agricultural Resources commissioner.

Since 2006, federal Farmers Market Promotion Program grants totaling more than $1 million have funded 15 Massachusetts projects, Alonzo said.

And now, it's easier than ever to find them. The National Farmers Market Directory (farmersmarkets.usda.gov) lists 8,268 markets, a 76 percent increase since 2008, and allows people to search by zip code and product mix, as well as providing directions and operating times.

Farmers markets "bring urban and rural communities together while creating economic growth and increasing access to fresh, healthy foods," Alonzo said.

Bob Marshall of Marshall's Farm in Gloucester said about 30 percent of his income comes from farmers markets, where he has been selling produce and honey for the past five years.

"It's a great way to sell what you grow because not everybody can drive to a farm," Marshall said. "This way, I can bring fresh produce to the city, and I can help a person eat better and get healthy."

One of his regulars at the Allston Village Farmers Market is Lisa Drayton, who has lost 50 pounds in the year since she started going.

"I went from being the takeout queen to making everything myself," said Drayton, 47, of Brighton. "I love being able to ask the farmers questions, like do they use pesticides or GMOs. I also like knowing I'm supporting the local economy. I'm helping these little guys. And they're helping me."
