WASHINGTON http://www.ottawasenatorsteamstore.com/adidas-chris-driedger-jersey , Oct. 4 (Xinhua) -- Americans express "more worry than enthusiasm" about driverless cars, robot caregivers and a future in which robots and computers perform many of the jobs currently done by humans, according to a survey released Wednesday by the Pew Research Center.
The nationally representative survey of 4 http://www.ottawasenatorsteamstore.com/adidas-bobby-ryan-jersey ,135 U.S. adults found that 72 percent of Americans are very or somewhat worried about the possibility of a robotic workforce that replaces humans -- more than double the share (33 percent) that is enthusiastic about this prospect.
Americans are also around three times as likely to express worry (67 percent) than enthusiasm (22 percent) about algorithms that can make hiring decisions without any human involvement, it said.
Public views toward driverless cars and robot caregivers are somewhat more balanced: 54 percent of Americans express worry about the development of automated vehicles with 40 percent expressing enthusiasm, while 44 percent are enthusiastic and 47 percent worried about the possibility of robotic caregivers.
The survey found that a majority of Americans are reluctant to ride in a driverless car, use a robot caregiver http://www.ottawasenatorsteamstore.com/adidas-alexandre-burrows-jersey , or apply for a job that used a computer program to select applicants, themselves, though a majority of Americans expect most cars on the road to be driverless within the next 50 years.
It also showed Americans generally strongly support policies that limit the reach of automation technologies and that place humans more fully in control of their processes.
"Similarly, the vast majority of Americans (87 percent) would favor a requirement that all driverless vehicles have a human in the driver's seat who could take over the car in the event of an emergency."
The survey also found roughly three-quarters of Americans (77 percent) think it is at least somewhat realistic that robots and computers might one day be able to perform many of the jobs currently done by humans.
And six percent of Americans report that they have already been impacted by automation in the form of lost jobs or wages, according to the survey.
In addition, many Americans think it very or somewhat likely that jobs such as fast food worker (77 percent) and insurance claims processor (65 percent) will be replaced by robots or computers during their lifetimes http://www.ottawasenatorsteamstore.com/adidas-zack-smith-jersey , while around half expect the same will be true of jobs such as software engineer (53 percent) or legal clerk (50 percent).
On the other hand, comparably few expect that teachers (36 percent) or nurses (20 percent) will be replaced by machines over that time period, the survey added. "
MELBOURNE， Aug. 9 (Xinhua) -- Australian scientists have discovered a link between watching television and lower back pain among women， but not men.
The research， undertaken by Melbourne's Monash University， found that watching TV could be a factor in lower back pain regardless of how physically active the woman was.
The study used data collected by the Australian Diabetes， Obesity and Lifestyle Study and a questionnaire to uncover the lifestyle factors responsible for back pain.
Sultana Monira Hussain， a musculoskeletal expert who led the study， said one in 10 Australians suffered from lower back pain at any given moment and three-quarters of Australians would ill suffer from an episode in their life.
Hussain said the study found little evidence linking physical activity to back pain intensity.
""We figured out it is not the physical activity， but the television viewing that increases the risk of disabling lower back pain in women but not in men，"" she told News Limited on Tuesday.
Previous studies have indicated that exercise has a beneficial impact on back pain while some have concluded it is an aggravator.
Women who watched TV for two or more hours a day experienced the worst lower back pain which is due to most people paying little attention to their posture while watching TV， Hussain said.
Approximately 80 percent of the 5，000 participants in the study suffered from lower back pain but only 12 percent of those had a high level of disabling pain.
