Thinking of variety is the best solution to satiation blues

Washington, May 20 (ANI): Sick of eating chocolates, playing the same computer game or hearing the same song again and again? Well, then the only way to come over such satiation is to think of the variety of songs you have listened to or meals you have eaten.

Such overdose of similar activities could lead to satiation, causing variety amnesia, which is a big problem for consumers and retailers.

Satiation is the process of consuming products and experiences to the point where they are less enjoyable.

But, now Joseph Redden, professor of marketing at the University of Minnesota’s Carlson School of Management, has found a cure for such satiation blues.

“People forget about the abundance of different experiences they have had and tend to focus on the repetition. Simply thinking about the variety of songs they have listened to or meals they have eaten will make people enjoy the activity again,” said Redden.

While time and variety were considered the only ways to cure satiation in the past, scientists have now said that just recalling variety may cure satiation faster.

“Intuition says that if time passes we will like something again: we call this ‘spontaneous recovery’. This isn’t the whole story. People don’t fully recover on their own with the mere passage of time. If I’m sick of chocolate, simply thinking about all the other desserts I’ve had since the last time I had chocolate helps cure my satiation. Time doesn’t seem to do that very well,” said Redden.

Satiation is a friction that prevents people from enjoying favourite activities. It prevents retailers from gaining repeat business.

Redden said: “The solution to satiation is to take the time to appreciate all the variety you have. The recommendation is straightforward: if consumers wish to keep enjoying their favourite experiences, then they should simply think of all the other related experiences they have recently had. So next time you get sick of healthy smoothies and think about grabbing a burger instead, try to recall all of the other drinks you have had since your last smoothie. Our findings suggest this will make your smoothie taste just a little bit better.”

The study will be published in the Journal of Consumer Research. (ANI)

Asteroids age quickly because of a ‘sun tan’

Munich, April 23 (ANI): A new study has revealed that asteroid surfaces age and redden much faster than previously thought – in less than a million years, all thanks to solar winds.

“Asteroids seem to get a ‘sun tan’ very quickly,” said lead author Pierre Vernazza. “But not, as for people, from an overdose of the Sun’s ultraviolet radiation, but from the effects of its powerful wind,” he added.

It has long been known that asteroid surfaces alter in appearance with time.

The observed asteroids are much redder than the interior of meteorites found on Earth, but the actual processes of this “space weathering” and the timescales involved were controversial.

Thanks to observations of different families of asteroids using ESO’s New Technology Telescope at La Silla and the Very Large Telescope at Paranal, as well as telescopes in Spain and Hawaii, Vernazza’s team have now solved the puzzle.

When two asteroids collide, they create a family of fragments with “fresh” surfaces.

The astronomers found that these newly exposed surfaces are quickly altered and change color in less than a million years – a very short time compared to the age of the Solar System.

“The charged, fast moving particles in the solar wind damage the asteroid’s surface at an amazing rate,” said Vernazza.

Unlike human skin, which is damaged and aged by repeated overexposure to sunlight, it is, perhaps rather surprisingly, the first moments of exposure (on the timescale considered) – the first million years – that causes most of the aging in asteroids.

By studying different families of asteroids, the team has also shown that an asteroid’s surface composition is an important factor in how red its surface can become.

After the first million years, the surface “tans” much more slowly. At that stage, the color depends more on composition than on age.

Moreover, the observations reveal that collisions cannot be the main mechanism behind the high proportion of “fresh” surfaces seen among near-Earth asteroids.

Instead, these “fresh-looking” surfaces may be the results of planetary encounters, where the tug of a planet has “shaken” the asteroid, exposing unaltered material.

Thanks to these results, astronomers will now be able to understand better how the surface of an asteroid, which often is the only thing we can observe, reflects its history. (ANI)

Obama’s ceremonial train trip brushes anti-slave trail

Wilmington, Delaware – In a series of treacherous journeys from the southern US states, abolitionist Harriet Tubman helped lead hundreds of African-Americans from slavery to freedom, years before the 1861-65 Civil War that brought an end to the practice in the United States.

One of the routes that Tubman would take was across the Christina River and into Wilmington, Delaware. It marked one of the dividing lines between states that still practised slavery in the south and free states to the north.

Some 150 years later, on the north side of the river is an Amtrak railway station. The station was passed through on Saturday by president-elect Barack Obama during his ceremonial “Whistle Stop” train journey to his inauguration in Washington.

“It’s ironic that an African-American president would stop by the same spot where slaves were freed,” remarked Louis Redden, 47, a Wilmington resident.

Tubman’s heroics are just one of many US historical nuggets from the centuries-long journey that brought Obama to Washington, where on Tuesday he will be making history of his own by becoming the country’s first black president.

Obama’s inauguration will mark a key step toward racial reconciliation in the United States. But Redden, himself an African- American, believed there was more history to be written as he watched Obama’s train leave the Wilmington station.

With Obama’s election in November, “America is really not there yet but on their way to abolishing racism,” said Redden.

“I don’t look for him to do any favours for African Americans. I look for him to do favours for all Americans,” Redden said.

Obama faces a myriad of problems and sky-high expectations at home and abroad as he takes the oath of office Tuesday in front of an anticipated record crowd of up to 2 million people on Washington’s National Mall.

Saturday’s 200-kilometre trip took nearly nine hours as the train slow-rolled through small towns, passing thousands of enthusiastic supporters who had braved minus-12-Centigrade temperatures in the hopes of catching a glimpse of the president- elect.

“He’s such an inspirational figure, he makes you want to come out in sub-zero temperatures,” said Savitha Krishna, 31, who came to the Wilmington stop along with her husband and five-month-old baby Nikhil.

Obama’s trip mirrored the inaugural journey of Civil War president Abraham Lincoln, a fellow Illinois politician who travelled by train all the way from Springfield, Illinois, for his own inauguration in 1861.

Obama began his ride in Philadelphia, the country’s first capital and site of the declaration of independence from Britain in 1776.

Three hours later in Wilmington he picked up vice president-elect Joe Biden, a veteran senator from Delaware, who continued living in his home state throughout his Senate career and famously commuted by rail to his office in Washington.

“It’s not every day you get to do your commute with the next president of the United States,” Biden joked to an estimated crowd of 7,000 that had come to the city’s station to wave their goodbyes.

Next, the train traveled to Baltimore, Maryland, where Francis Scott Key was inspired to write the country’s national anthem during the war of 1812. Key was held under British guard in Baltimore Harbour watching anxiously as US forces at Fort McHenry repelled an attack by the British Navy, and described his relief to see the US flag still waving when the smoke cleared.

An estimated 40,000 people turned out at city hall near the same harbour on Saturday to hear Obama call for a new “declaration of independence” from the political divisions of the past to address the crises currently facing the United States, including a devastating recession as well as wars in Afghanistan and Iraq.

“We should never forget that we are the heirs of those early (American) patriots … who somehow believed that they had the power to make the world anew,” Obama said. “That is the spirit that we must reclaim today.”

If you ask his supporters, Saturday’s train journey may indicate Obama’s willingness to address yet another urgent problem facing the United States – its crumbling public transport system.

“We refuse to deal with public transportation in this country,” said Hal Blockson, a 69-year-old retired school counselor. “Barack and Joe Biden – especially Joe Biden – are going to change that.” (dpa)
