Dissent Magazine - Winter 2011 Issue - Got Dough? Public Scho... - 59 views

  • To justify their campaign, ed reformers repeat, mantra-like, that U.S. students are trailing far behind their peers in other nations, that U.S. public schools are failing. The claims are specious. Two of the three major international tests—the Progress in International Reading Literacy Study and the Trends in International Math and Science Study—break down student scores according to the poverty rate in each school. The tests are given every five years. The most recent results (2006) showed the following: students in U.S. schools where the poverty rate was less than 10 percent ranked first in reading, first in science, and third in math. When the poverty rate was 10 percent to 25 percent, U.S. students still ranked first in reading and science. But as the poverty rate rose still higher, students ranked lower and lower. Twenty percent of all U.S. schools have poverty rates over 75 percent. The average ranking of American students reflects this. The problem is not public schools; it is poverty. And as dozens of studies have shown, the gap in cognitive, physical, and social development between children in poverty and middle-class children is set by age three.
  • Drilling students on sample questions for weeks before a state test will not improve their education. The truly excellent charter schools depend on foundation money and their prerogative to send low-performing students back to traditional public schools. They cannot be replicated to serve millions of low-income children. Yet the reform movement, led by Gates, Broad, and Walton, has convinced most Americans who have an opinion about education (including most liberals) that their agenda deserves support.
  • THE COST of K–12 public schooling in the United States comes to well over $500 billion per year. So, how much influence could anyone in the private sector exert by controlling just a few billion dollars of that immense sum? Decisive influence, it turns out. A few billion dollars in private foundation money, strategically invested every year

  • Hundreds of private philanthropies together spend almost $4 billion annually to support or transform K–12 education, most of it directed to schools that serve low-income children (only religious organizations receive more money). But three funders—the Bill and Melinda Gates Foundation, the Eli and Edythe Broad (rhymes

It suggests courses with simulations, with constant feedback, and with interactive software that can tailor instruction and tutoring to individual students. It likes courses that students can use to teach themselves. And it demands open access to everything: "All online and technology-enabled courses must permit free public use and distribution, including the ability to re-use course modules, via an online repository for learning materials to be established by the federal government.... That's because the government is requiring that all work supported by the grants be made available under what's known as a "Creative Commons Attribution 3.0 License," which Mr. Green described as 'one of the most open content licenses that exists.'"

Electricity FERC - 10 views

  • Regulatory Changes by the Federal Energy Regulatory Commission
  • FERC Orders 888 and 889
  • On April 24, 1996, FERC issued Orders 888 and 889, which encourage wholesale competition.  The primary objective of these orders is the elimination of monopoly power over the transmission of electricity.  To achieve this objective, FERC requires all public utilities that own, control, or operate facilities used for transmitting electric energy in interstate commerce to: file open access nondiscriminatory transmission tariffs containing minimum terms and conditions, take transmission service (including ancillary services) for their own new wholesale sales and purchases of electricity under open access tariffs, develop and maintain a same-time information system that will give existing and potential  users the same access to transmission information that the public utility enjoys, and separate the transmission from generating and marketing functions and communications.

  • Recovery of stranded costs is perhaps the most contentious issue confronting regulators in promoting competition.  Stranded costs (or assets) are costs that have been prudently incurred by utilities to serve their customers but cannot be recovered if the consumers choose other electricity suppliers. One study has estimated current stranded assets at $88 billion, and estimates of projected stranded costs range from $10 billion to $500 billion. In its Order 888, FERC reaffirmed "that the recovery of legitimate, prudent and verifiable stranded costs should be allowed." FERC's directive is grounded in the belief that the recovery of stranded costs "is critical to the successful transition of the electricity industry to a competitive, open-access environment." For this purpose, direct assignment of costs to departing customers was selected as the appropriate method for recovery of stranded costs.

  • The price valued the digital pin board company, which lets people save images and links from around the web, at $12.7 billion. That is a little above its last private fund-raising round, which had pegged the company at $12 billion.By selling at $19 a share, Pinterest raised $1.6 billion from big investors
  • In its I.P.O. prospectus, Pinterest emphasized its differences from some of those services. Pinterest is not a social media app for hanging out with celebrities or broadcasting one’s life, the company said. It is meant to be personal. The company’s 250 million monthly active users, called “pinners,” come to the site to plan their lives, including home projects, weddings and meals.

    This post makes a solid point about the seemingly lost practice of coding with the proliferation of more ubiquitous technology. While these advances have connected billions, what does this mean for future job markets, innovation, etc. Get the kids coding! I ordered my Raspberry Pi today and look forward to the day when I can get my (now 3-year old) son into coding.

Hydrogen vehicle - Wikipedia, the free encyclopedia - 13 views

      Is hydrogen sustainable? depends on the source. see this highlight.
  • While methods of hydrogen production that do not use fossil fuel would be more sustainable
  • The challenges facing the use of hydrogen in vehicles include production, storage, transport and distribution.

  • The hydrogen infrastructure consists mainly of industrial hydrogen pipeline transport and hydrogen-equipped filling stations like those found on a hydrogen highway. Hydrogen stations which are not situated near a hydrogen pipeline can obtain supply via hydrogen tanks, compressed hydrogen tube trailers, liquid hydrogen tank trucks or dedicated onsite production.
  • Hydrogen use would require the alteration of industry and transport on a scale never seen before in history. For example, according to GM, 70% of the U.S. population lives near a hydrogen-generating facility but has little access to hydrogen, despite its wide availability for commercial use.[64] The distribution of hydrogen fuel for vehicles throughout the U.S. would require new hydrogen stations that would cost, by some estimates approximately 20 billion dollars[65] and 4.6 billion in the EU.[66] Other estimates place the cost as high as half trillion dollars in the United States alone.[67]
  • Hydrogen fuel does not occur naturally on Earth and thus is not an energy source, but is an energy carrier. Currently it is most frequently made from methane or other fossil fuels. However, it can be produced from a wide range of sources (such as wind, solar, or nuclear) that are intermittent, too diffuse or too cumbersome to directly propel vehicles. Integrated wind-to-hydrogen plants, using electrolysis of water, are exploring technologies to deliver costs low enough, and quantities great enough, to compete with traditional energy sources.[2]

OWS's Beef: Wall Street Isn't Winning It's Cheating | Matt Taibbi | Rolling Stone - 0 views

  • Just recently, the French and Belgian authorities cooked up a massive bailout of the French bank Dexia, whose biggest trading partners included, surprise, surprise, Goldman, Sachs and Morgan Stanley. Here's how the New York Times explained the bailout: To limit damage from Dexia’s collapse, the bailout fashioned by the French and Belgian governments may make these banks and other creditors whole — that is, paid in full for potentially tens of billions of euros they are owed. This would enable Dexia’s creditors and trading partners to avoid losses they might otherwise suffer... When was the last time the government stepped into help you "avoid losses you might otherwise suffer?" But that's the reality we live in. When Joe Homeowner bought too much house, essentially betting that home prices would go up, and losing his bet when they dropped, he was an irresponsible putz who shouldn’t whine about being put on the street. But when banks bet billions on a firm like AIG that was heavily invested in mortgages, they were making the same bet that Joe Homeowner made, leaving themselves hugely exposed to a sudden drop in home prices. But instead of being asked to "suck it in and cope" when that bet failed, the banks instead went straight to Washington for a bailout -- and got it.
