This is the largest nationally representative study to date of the toll taken by sepsis and pneumonia, two conditions often caused by deadly microbes, including the antibiotic-resistant bacteria MRSA. Such infections can lead to longer hospital stays, serious complications and even death. "In many cases, these conditions could have been avoided with better infection control in hospitals," said Ramanan Laxminarayan, Ph.D., principal investigator for Extending the Cure, a project examining antibiotic resistance based at the Washington, D.C. think-tank Resources for the Future. "Infections that are acquired during the course of a hospital stay cost the United States a staggering amount in terms of lives lost and health care costs," he said. "Hospitals and other health care providers must act now to protect patients from this growing menace." Laxminarayan and his colleagues analyzed 69 million discharge records from hospitals in 40 states and identified two conditions caused by health care-associated infections: sepsis, a potentially lethal systemic response to infection and pneumonia, an infection of the lungs and respiratory tract. The researchers looked at infections that developed after hospitalization. They zeroed in on infections that are often preventable, like a serious bloodstream infection that occurs because of a lapse in sterile technique during surgery, and discovered that the cost of such infections can be quite high: For example, people who developed sepsis after surgery stayed in the hospital 11 days longer and the infections cost an extra $33,000 to treat per person. Even worse, the team found that nearly 20 percent of people who developed sepsis after surgery died as a result of the infection. "That's the tragedy of such cases," said Anup Malani, a study co-author, investigator at Extending the Cure, and professor at the University of Chicago. "In some cases, relatively healthy people check into the hospital for routine surgery. They develop sepsis because of a lapse in infection control—and they can die." The team also looked at pneumonia, an infection that can set in if a disease-causing microbe gets into the lungs—in some cases when a dirty ventilator tube is used. They found that people who developed pneumonia after surgery, which is also thought to be preventable, stayed in the hospital an extra 14 days. Such cases cost an extra $46,000 per person to treat. In 11 percent of the cases, the patient died as a result of the pneumonia infection.

Solar-powered drip irrigation enhances food security in the Sudano–Sahel documents a field research project which found that: "solar-powered drip irrigation significantly augments both household income and nutritional intake, particularly during the dry season, and is cost effective compared to alternative technologies" Over the decades, irrigation has been shown to greatly increase agricultural productivity. Drip irrigation is spreading rapidly in Africa, with significant benefits. "Drip irrigation delivers water (and fertilizer) directly to the roots of plants, thereby improving soil moisture conditions; in some studies, this has resulted in yield gains of up to 100%, water savings of up to 40–80%, and associated fertilizer, pesticide, and labor savings over conventional irrigation systems" The solar-powered systems, however, look to offer the potential for even better results. From the study on impacts of PVDI systems it was reported: "The women’s agricultural group members utilizing the PVDI systems became strong net producers in vegetables with extra income earned from sales, significantly increasing their purchases of staples, pulses, and protein during the dry season, and oil during the rainy season. Finally, survey respondents were asked how frequently they were unable to meet their household food needs. Based on the frequency and most recent incident, households were assigned a food insecurity score ranging from zero (no problems during the previous year) to one (perpetually unable to meet food needs). This score changed significantly for project beneficiaries, as they were 17% less likely to feel chronically food-insecure. In short, the PVDI systems had a remarkable effect on both year-round and seasonal food access."

In his decision, Judge Robert Cleland said that CAN's case "must fail" because the company did not provide evidence that White had intended to profit from the domains. He did acknowledge, however, that White made some attempt to damage CAN's business by climbing the search rankings, but that it was only to warn other potential customers—an action that is protected under the First Amendment. Because White's websites didn't represent themselves as the real company websites for CAN and they provided accurate contact information, they were clearly gripe sites and did not infringe on CAN's marks. As noted by TechLaw, the ruling included some extra details about what is required (or in this case, not required) to qualify as a "gripe site." careeragentsnetworks.biz did not include a disclaimer stating that it is not affiliated with CAN, for example—something that many gripe sites do for the explicit purpose of avoiding lawsuits like this—but that didn't make a difference in the ruling. The decision has been applauded as a victory for the First Amendment, but is a frustrating one for trademark holders. Companies have been notoriously unhappy with the existence of gripe sites, though not everyone gives into legal threats. In 2007, we covered a case involving an Ars reader who was fighting a legal battle against Lowe's over his site, lowes-sucks.com, and in 2009, Goldman Sachs made headlines for trying to bully the creator of Goldmansachs666.com into shutting the site down. When we spoke with EFF staff attorney Corynne McSherry in 2007, she told us that the courts have been clear that "gripe sites like this are protected—in fact, they want people to speak freely and share information about their experiences with various companies." As long as they don't represent themselves as the real company, it seems the courts are still on the side of dissatisfied consumers.

No silver bullets. This is the simple premise of Diane Ravitch’s new book, “The Death and Life of the Great American School System,” which is being brought out this week by Basic Books. Written by one of our nation’s most respected scholars, it has been eagerly awaited. But it has also been, at least in some quarters, anticipated with a certain foreboding, because it was likely to debunk much of the conventional — and some not so conventional — wisdom surrounding education reform.

What of the once-great comprehensive high schools, institutions with history and in some cases a track record of success going back generations? As time moves on, it is fast becoming clear that the new small schools, many with inane themes (how about the School of Peace and Diversity?), can never substitute for a good neighborhood high school, which can become a center of communal life and pride. Ms. Ravitch’s report underscores the fact that the trick is to fix the neighborhood schools beset with problems, not destroy them.

It is not only the foundations that Ms. Ravitch blames for the current crisis: government has also failed in the attempt to reform the schools from above, lacking a clear perspective of how schools work on a day-to-day basis. Thus, the major federal initiative, No Child Left Behind, well intentioned as it may have been, ended up damaging the quality of education, not improving it. While the federal government declares schools as “failing” and prescribes sanctions for schools not meeting its goal of “annual yearly progress,” it is the states that are allowed to write and administer the tests. This has led to a culture of ever easier tests and more test preparation rather than real instruction. More ominously, it led to such scandals as the New York State Education Department lowering the “cut scores” that define the line between passing and failing. Ms. Ravitch suggests that the proper roles of the states and federal government have been reversed under NCLB. Maybe the standards for achievement should be set in Washington, which, after all, administers the National Assessment of Educational Progress , and the solutions found at the local level, using the accurate data provided by Washington. Instead of moving in a different direction from the failed NCLB model of the Bush Administration, the Obama administration has adopted and expanded on them.
