Self-driving Bus With No Back-Up Driver Nears California

A pair of $250,000 autonomous buses began driving around an empty San Francisco Bay Area parking lot on Monday, preparing to move onto a local public road in California’s first pilot program for a self-driving vehicle without steering wheel or human operator.

California and other states are weighing the opportunities of becoming a hub of testing a technology that is seen as the future of transportation and the risks from giving up active control of a large, potentially dangerous vehicle.

In most tests of self-driving cars there is still a person seated at the steering wheel, ready to take over, although Alphabet Inc’s Waymo tested a car with no steering wheel or pedals in Austin, Texas, as early as 2015.

The bus project in San Ramon, at the Bishop Ranch office park complex, involves two 12-passenger shuttle buses from French private company EasyMile.

The project is backed by a combination of private companies and public transit and air quality authorities, with the intention of turning it into a permanent, expanded operation, said Habib Shamskhou, a program manager who strolled in front of a moving bus to show that the vehicle would notice him and react. It stopped.

In a test for reporters, one bus cruised a block-long circuit so consistently that it created a dirt track on the tarmac.

California legislators late last year passed a law to allow slow-speed testing of fully autonomous vehicles without steering wheels or pedals on public roads, with the Bishop Ranch test in mind.

The shuttle buses will test for a few months in the parking lots before operators apply for Department of Motor Vehicles approval under the new law. The vehicles are expected to swing onto the local street late this year or early in 2018.

Look Up to See Future of the Circus

For generations, the circus meant big entertainment – elephants, lion tamers, dancing bears, high-wire acts. But times, and tastes, have changed. In May, after nearly a century and a half, the Ringling Brothers/Barnum and Bailey Circus – “the greatest show on earth” – will close.

But circuses are alive and well, largely without the ringmasters and exotic animals. Instead, they use a combination of music, amazing acrobatics and story-telling to transfix their audiences.

“Circus artists have been producing new and incredible circus acts and apparatuses and shows that have an artistic context and theatrical storylines, or well-drawn characters,” Adam Woolley notes. “And this has been happening around the world for the past 10, 15 years or so.”

Woolley runs Circus Now, a non-profit organization which supports and promotes contemporary circus arts, which combine traditional circus skills, like acrobatics, juggling and trapeze, with theatrical techniques to tell a story.

 

Cutting-edge entertainment

Here in the U.S., smaller traditional troupes, like the Kelly Miller Circus, still pitch their tents across the country.  But Woolley says there are more experimental companies that are pushing the art form, and those are the ones Circus Now works with.  

“Audiences or families who might not be interested to go see, you know, some very avant garde modern dance, will still go see the circus.  You know, people who would prefer to watch movies or television than go see a play, will probably still come see the circus.”

Circus Now’s festival in New York this month featured the Race Horse Company from Finland. Acrobat Rauli Kosonen formed it with a couple of other performers nine years ago, because he says there’s something unique about circus.

“I think it’s really pure art form, in the sense that you can really feel the risks – there’s a lot of risks, so you can get a lot of adrenaline, while you watch it, if there is kind of tricks that make your heart bounce.  Because it’s real.  They can see if they make a mistake, they might get hurt.  So, I guess that’s always been why circus is appealing.  It reminds us that, uh, we’re humans.”  

And Kosonen – whose specialty is trampoline – has the broken bones to prove it. 

“Well, I had three operations,” he admits, adding ruefully, “it’s part of the job; sometimes you don’t get lucky.”  

New York’s Only Child Aerial Theatre also performed during the festival. Kendall Ridleigh, one of the troupe’s founders, says they shy away from calling themselves a circus.

“Just because there is the implication that the skills or the spectacle is sort of paramount, rather than the narrative.  And we really have tried to keep the narrative the most important element and have the skills really drive and support the narrative.”

In a former factory in Brooklyn, Only Child is rehearsing its latest show, Asylum.  It’s set in a mental institution in the 1970s.  There’s a story, but there’s no spoken dialogue, says co-founder Nicki Miller.

“We would describe it as a theater piece that includes a lot of aerial work, dance, some recorded music, some live music and overhead projection and shadow.  So, the story is told, rather than through dialogue, through the conversation of those theatrical vocabularies, instead,” Miller said. 

So, even as the performers do aerial tricks, they’re dressed like mental patients, doctors and nurses, says Rileigh. There are no sparkles or spandex. But, they’re still doing stuff high off the ground…without a net.  

A big tent for big stories

Circus Now’s Adam Woolley says contemporary circus companies, even with their different skill sets and artistic approaches, all fall under what can only be called the “big tent” of what circus can be.  

He says they share the belief that with lots of practice and hard work, they can accomplish the impossible.

“That’s the core idea that everyone in circus believes in and everyone in circus tries to impart to the audiences – that ‘I have dedicated my life to this seven minutes of performance and honed my skill to the place where  I’m going to accomplish something in front of you now that you did not think could be done.’” 

And that’s what still thrills audiences.

Heavy Social Media Use Could Lead to Isolation in Young Adults

Young adults who spend a lot of time looking for social connections on social media could instead find themselves feeling socially isolated, a new study suggests.

Researchers looked at the social media habits of 1,787 American adults aged 19 to 32, asking them how much they used 11 popular social media sites, including Facebook, YouTube, Instagram, Snapchat, Twitter and LinkedIn, among others.

After controlling for various demographic factors, they found that people who used social media more than two hours per day “had twice the odds for perceived social isolation than their peers who spent less than half an hour on social media each day.”

Those who visited social media sites 58 times a week or more “had about triple the odds of perceived social isolation than those who visited fewer than nine times per week.”

Writing in the American Journal of Preventative Medicine, researchers from the University of Pittsburgh School of Medicine add that increased social isolation has been associated with “an increased risk for mortality.”

“This is an important issue to study because mental health problems and social isolation are at epidemic levels among young adults,” said lead author Dr. Brian A. Primack, director of Pitt’s Center for Research on Media, Technology and Health. “We are inherently social creatures, but modern life tends to compartmentalize us instead of bringing us together. While it may seem that social media presents opportunities to fill that social void, I think this study suggests that it may not be the solution people were hoping for.”

“We do not yet know which came first, the social media use or the perceived social isolation,” said senior author Dr. Elizabeth Miller, professor of pediatrics at Pitt and chief of the Division of Adolescent and Young Adult Medicine at Children’s Hospital of Pittsburgh of UPMC.

“It’s possible that young adults who initially felt socially isolated turned to social media. Or it could be that their increased use of social media somehow led to feeling isolated from the real world. It also could be a combination of both. But even if the social isolation came first, it did not seem to be alleviated by spending time online, even in purportedly social situations.”

Researchers social media may cause feelings of social isolation by replacing “authentic social experiences;” causing feelings of exclusion stemming from seeing photos of friends having fun at events to which they were not invited; or may lead people to think others have happier or more successful lives due to often idealized presentation of one’s life online.

Researchers say more study needs to be done, but they say doctors should ask patients about social media use if they show symptoms of social isolation.

“People interact with each other over social media in many different ways,” said Primack, “In a large population-based study such as this, we report overall tendencies that may or may not apply to each individual. I don’t doubt that some people using certain platforms in specific ways may find comfort and social connectedness via social media relationships. However, the results of this study simply remind us that, on the whole, use of social media tends to be associated with increased social isolation and not decreased social isolation.”
