London, May 11 (IANS) A long wait before asking for feedback about a service or product would increase the odds of getting a better review by your customers, researchers say.
The findings revealed that people who waited longer or travelled farther before authoring a review gave more favourable evaluations.
"If someone visited a particular restaurant in their home town and then in another state, he or she gave a better star rating when the restaurant was out of town," said lead author Nina Huang from Temple University in Pennsylvania.
The investigators analysed data from more than 166,000 online restaurant reviews on travel website TripAdvisor.com that provides reviews of travel-related content.
They used a Google Maps application and information in the reviewer's profile to calculate the distance between the author's home and the restaurant.
The same positive effect occurred when reviewers waited two or more months versus one month or less to write a review.
The researchers discovered that reviewers who experienced both time delay and greater physical distance from the restaurant gave the highest ratings.
It might be wise to take a moment to distinguish between reviews written by locals versus travellers before judging a product or service, the authors noted in a paper published in the Journal of Consumer Psychology.
"When people are reading a review, they assume it is objective," Huang noted, adding, "We found that reviews are not always as objective as we thought. Time and space distance is going to bias someone's evaluation of certain experiences."

New York, May 11 (IANS) Far from being rejuvenating, a peaceful walk in nature after a difficult day at work can make people prone to anxiety more stressed, new research suggests.
They should instead take a walk in a busy, urban environment, the study said.
What should you do after a difficult day at work? Many people would take a peaceful walk in nature, but this may not be a wise choice for everyone.
A study found evidence that people who are more prone to anxiety should instead take a walk in a busy, urban environment.
"Previous literature says that natural environments tend to restore cognitive abilities better than urban environments, but we questioned whether this one-sided perspective was accurate," said study lead author Kevin Newman, assistant professor at Providence College in Rhode Island, US.
The researchers started by asking participants to perform tasks that drained them mentally, such as writing sentences without using the letters "A" or "N."
Then participants answered questions that revealed their level of neuroticism, such as whether they were a worrier, irritable, highly strung or experienced moods that often go up and down.
Then all the participants performed tasks that exposed them to words or pictures associated with either a natural or urban environment.
Surprisingly, the results revealed that people with neurotic personalities had more success restoring their cognitive abilities after they viewed words related to a busy urban environment.
In fact, nature could provide frenetic, stressful cues when the participants were exposed to words like "bear," "cliff" and "thunder."
The nature-related words, however, were more beneficial for people who were not generally neurotic.
The findings appeared in the Journal of Consumer Psychology.
"People tended to do better in environments that fit with their personality," Newman said.
"Imagine someone with a neurotic personality like Woody Allen. If you put him in a forest it could be very off-putting rather than rejuvenating," he said.

London, May 10 (IANS) Decisions are best taken when you are full. Researchers have found that the hormone ghrelin -- that is released before meals and is known to increase the appetite -- has a negative effect on both decision making and impulse control.
"For the first time, we have been able to show that increasing ghrelin levels that are seen prior to meals or during fasting, causes the brain to act impulsively and also affects the ability to make rational decisions," said one of the researchers Karolina Skibicka from Sahlgrenska Academy, University of Gothenburg in Sweden.
When hungry, the hormone ghrelin is produced in the stomach. In the new study conducted on rats, the hormone has been shown to have a negative effect on decision making capabilities and impulse control.
The rats can be trained to be rewarded (with sugar) when they execute an action such as pressing a lever ("go") -- or instead they can be rewarded only when they resist pressing the lever ("no-go") when an appropriate signal is given.
They learn this by repeatedly being given a signal, for example, a flash of light or a buzzing sound that tells them which action should be executed for them to receive their reward.
An inability to resist pressing the lever, when the "no-go" signal is given, is a sign of impulsivity.
Researchers found that rats given ghrelin directly into the brain, which mimics how the stomach would notify us of a need to eat, were more likely to press the lever instead of waiting, despite it causing them lose their reward.
Higher levels of ghrelin prevented the rats from being able to wait for the greater reward, said the study published in the journal Neuropsychopharmacology.

Travel and Tourism
Cairo, May 10 (IANS/AKI) The number of tourists visiting Egypt fell by 47.2 percent between March 2015 and the same month this year, according to official statistics cited by state-run daily Al-Ahram.
A total of 440,700 tourists visited Egypt in March, compared with 834,600 in the same month last year, said the country's central statistics office, quoted by Al-Ahram.
Egypt's authorities blame the slump in tourist bookings on fears caused by the downing of a Russian passenger jet over Sinai in October which killed all 224 people on board.
The Islamic State jihadist group claimed it brought down the flight which was travelling from the Red Sea resort of Sharm El-Sheikh to St Petersburg.
Western Europeans formed the biggest group of visitors to Egypt (slightly over one-third) followed by tourists from the Middle East and eastern Europe.
Egypt was most popular with Germans, Saudi Arabians and Ukrainians.

New York, May 10 (IANS) Researchers including one of Indian origin from the US Department of Energy's Berkeley Lab have engineered a strain of bacteria that enables a "one-pot" method for producing advanced biofuels from a slurry of pre-treated plant material.
The Escherichia coli (E coli) is able to tolerate the liquid salt used to break apart plant biomass into sugary polymers.
Developing ionic-liquid-tolerant bacteria eliminates the need to wash away the residual ionic liquid.
The achievement is a critical step in making biofuels a viable competitor to fossil fuels because it helps streamline the production process.
Being able to put everything together at one point, walk away, come back and then get your fuel, is a necessary step in moving forward with a biofuel economy," said principal investigator Aindrila Mukhopadhyay, vice president of the fuels' synthesis division at the Joint BioEnergy Institute (JBEI), Berkeley Lab.
"The E coli we've developed gets us closer to that goal. It is like a chassis that we build other things onto, like the chassis of a car. It can be used to integrate multiple recent technologies to convert a renewable carbon source like switchgrass to an advanced jet fuel," he added.
The basic steps of biofuel production start with deconstructing, or taking apart, the cellulose, hemicellulose and lignin that are bound together in the complex plant structure.
Enzymes are then added to release the sugars from that gooey mixture of cellulose and hemicellulose, a step called saccharification.
Bacteria can then take that sugar and churn out the desired biofuel.
The multiple steps are all done in separate pots.
Researchers pioneered the use of ionic liquids - salts that are liquid at room temperature - to tackle the deconstruction of plant material because of the efficiency with which the solvent works.
E. coli remains the workhorse microbial host in synthetic biology and in the new study, using the ionic-liquid-tolerant E. coli strain, we can combine many earlier discoveries to create an advanced biofuel in a single pot," the authors noted.
"Ultimately, we hope to develop processes that are robust and simple where one can directly convert any renewable plant material to a final fuel in a single pot," Mukhopadhyay noted in a paper published in the journal Green Chemistry.
