Projected precipitation increases are bad news for water quality

News From NSF - Fri, 07/28/2017 - 16:44

Increased precipitation from a changing climate could pollute U.S. waterways with excess nitrogen, increasing the likelihood of severe water quality impairment from coast to coast, according to a new study by scientists Eva Sinha and Anna Michalak of the Carnegie Institution for Science and Venkatramani Balaji of Princeton University.

The results are published in this week's issue of the journal Science.

The effects will be especially strong in the Midwest and ...

NSF-funded supercomputer Stampede2 forges new frontier in advanced computing

News From NSF - Fri, 07/28/2017 - 11:07

The National Science Foundation (NSF) today realized the initial phase of its $30 million investment to upgrade the nation’s computational research infrastructure through the dedication of Stampede2, one of the most powerful supercomputing systems in the world. Based at the Texas Advanced Computing Center (TACC) at The University of Texas at Austin, this strategic national resource will ...

A Weak Argument that Silicon Valley is Pushing Coding Into American Classrooms through Code.org

ComputingEd - Fri, 07/28/2017 - 07:00

When the New York Times does an article on Code.org, it’s worth noting.  I had my class on Computing and Society read the essay and critique it, and they were dubious.  They have a bias — they’re all Georgia Tech students in STEM, and almost all majoring in Computer Science.  They tend to think learning to code is a good thing.  Still, they were concerned about the article, with good reason.  They wondered, “Where exactly is Code.org doing something wrong?”

I had similar concerns. I read the quote from Jane Margolis (“It gets very problematic when industry is deciding the content and direction of public education”) and thought, “Jane didn’t just say that.  She would have explained what she meant by ‘problematic.'”  It felt to me like the quote was taken out of context.

Is Code.org really “deciding” what goes into public education?  Or are they simply influencing those who do decide?  Maybe Silicon Valley is having undue influence. This article didn’t really make the case.

Code.org’s multilevel influence machine also raises the question of whether Silicon Valley is swaying public schools to serve its own interests — in this case, its need for software engineers — with little scrutiny. “If I were a state legislator, I would certainly be wondering about motives,” said Sarah Reckhow, an assistant professor of political science at Michigan State University. “You want to see public investment in a skill set that is the skill set you need for your business?”Mr. Partovi, 44, said he simply wanted to give students the opportunity to develop the same skills that helped him and his backers succeed. He immigrated as a child to the United States from Iran with his family, went on to study computer science at Harvard, and later sold a voice-recognition start-up he had co-founded to Microsoft for a reported $800 million.

“That dream is much less accessible if you are in one of America’s schools where they don’t even tell you you could go into that field,” Mr. Partovi said.

Even so, he acknowledged some industry self-interest. “If you are running a tech company,” he said, “it’s extremely hard to hire and retain engineers.”
