But its other two “big bets,” Grauer says, are (1) using the vast data at its disposal (in terms of the sorts of content and help students are looking for) to create its own content and (2) building out its portal for educators.
Course Hero was founded in 2006, one of a slew of websites that enabled students to post and download syllabi, worksheets, essays, previous exams and other course materials. Among its differentiators was that the materials were all tied to specific courses.
Oakley failed an early test in a course on circuits, she says, because she didn't understand a concept the professor had never introduced in class. Other students didn't fail -- and when she pressed, she learned that most of them had had an old exam of his that revealed the trick.
Grauer, the Course Hero CEO and co-founder, says the company combats potential academic misconduct in every way it can. Any time it identifies cases of abuse, "or where it becomes exceedingly clear that there is abuse," site monitors "remove that content.".
Higher education is evolving "to be more collaborative and dynamic and less lecture/exam/research paper-based," Rettinger adds. And when that happens, he says, "technology and pedagogy will come together in ways that really benefit students.".
As Malcolm Forbes Baldwin , the acting chairman of the president’s Council for Environmental Quality, told industry executives in 1981, “There can be no more important or conservative concern than the protection of the globe itself.”. The issue was unimpeachable, like support for veterans or small business.
7, 1989, than in the entire history of civilization preceding it. In 1990, humankind emitted more than 20 billion metric tons of carbon dioxide. By 2017, the figure had risen to 32.5 billion metric tons, a record.
The first suggestion to Rafe Pomerance that humankind was destroying the conditions necessary for its own survival came on Page 66 of the government publication EPA-600/7-78-019. It was a technical report about coal, bound in a coal-black cover with beige lettering — one of many such reports that lay in uneven piles around Pomerance’s windowless office on the first floor of the Capitol Hill townhouse that, in the late 1970s, served as the Washington headquarters of Friends of the Earth. In the final paragraph of a chapter on environmental regulation, the coal report’s authors noted that the continued use of fossil fuels might, within two or three decades, bring about “significant and damaging” changes to the global atmosphere.
Wirth, in his keynote on June 27, called for the world to reduce emissions by 20 percent by 2000, with an eventual reduction of 50 percent. Other speakers likened the ramifications of climate change to a global nuclear war, but it was the emissions target that was heard in Washington, London, Berlin, Moscow.
The world has warmed more than one degree Celsius since the Industrial Revolution. The Paris climate agreement — the nonbinding, unenforceable and already unheeded treaty signed on Earth Day in 2016 — hoped to restrict warming to two degrees.
Beginning in the spring of 1979, Pomerance arranged informal briefings with the E.P.A., the National Security Council, The New York Times, the Council on Environmental Quality and the Energy Department, which, Pomerance learned, had established an Office of Carbon Dioxide Effects two years earlier at MacDonald’s urging.
Jule Charney, the father of modern meteorology, would gather the nation’s top oceanographers, atmospheric scientists and climate modelers to judge whether MacDonald’s alarm was justified — whether the world was, in fact, headed to cataclysm. Pomerance was amazed by how much momentum had built in such a short time.

Here the word important in a way Is actually contradictory, because the authors are saying in one breath that these other mechanisms are important, but in the next breath they're saying, they only have small impacts. Those two things don't dovetail, so let's just again remove the word important.
The subject is the fear. It's a really long subject, though. Because we don't get into the main verb or the predicate until has not been realized. So this is an example where the authors take too long to get to the main verb of the sentence and then the verb is a boring passive verb.
The medium used to test carbohydrate fermentation is a nutrient broth that contains a fermentable carbohydrate . (usually a monosaccharide or a disaccharide), peptone (amino acids) as well as a pH indicator. The pH of the . medium is adjusted to approximately 7.5, so it appears orange/red when using phenol red.
