Example Input: More than 30 000 brain scientists are in Washington  D.C.  this week attending the Society for Neuroscience meeting. One of the hot topics this year is mental disorders such as depression and schizophrenia and autism.  NPR science correspondent Jon Hamilton  has just come from the meeting to talk about some of what  he 's been seeing and hearing. Hi  John. Thanks for coming.
 JON HAMILTON   BYLINE: Hi.
 HAMILTON : Twenty years ago  I'd say it didn't contribute much  but things are really changing. And I was really surprised. I was going through the abstracts to this year's meeting  and there were nearly a thousand papers that mentioned depression. There were 500 that mentioned schizophrenia or autism. And just this morning  there was this study on how - looking at the brain tissue of people with obsessive compulsive disorder and how it's different.
MARTIN: That's NPR's science correspondent Jon Hamilton. Jon  thanks so much.

Example Input: Ogard and the co-founder of Barbie Savior  Emily Worrall  hope that the guide will make young volunteers and travelers more aware of what they're posting. Advice in the ten-point checklist includes: Be respectful of different cultures and traditions  avoid sweeping generalizations  challenge perceptions.
 Worrall  recalls  her  own experience a decade ago. When  she  was 17   she  went on a volunteer trip to Uganda.  She  shared photos of  herself  and the orphans  she  was helping with  her  family and friends. They showered  her  with praise. "They told me  'Wow  you're doing such amazing work.' They put me on a pedestal "  she  says. At the time   she  didn't consider the children's privacy or vulnerability. Years later  it became inspiration for this Barbie Savior post:
Ogard and  Worrall  don't want the guidelines to discourage volunteers from posting photos on social media. They just want photo-takers to reflect on what they're sharing. Ask for a subject's consent  they say. Show your social followers something different.
If you need inspiration   Worrall  says  check out some of the positive imagery from charities that received a Golden Radiator award in Radi-Aid's annual contest for the best and worst charity ads. These ads  like those from an NGO called Mama Hope  show local people actively engaged in helping others in their community.
If you're staying with a family in a low-income environment and they allow you to take a photo with their children  use it as a "great opportunity to challenge stereotypes "  Worrall  says. That might mean providing details and context — names  locations  personal stories — in an extended caption on social media.
And if a child gets excited when they see you pull out your tablet or smartphone and ask to take a photo with you  that doesn't mean it's OK to do so. "It's a cop out to say  well  they want it "  Worrall  says. "A child can't make that kind of decision."
