The Super Dual Auroral Radar Network (SuperDARN) is a network of HF radars used to study phenomena in the Earth’s magnetosphere, ionosphere, and upper atmosphere. Phenomena in the upper mesosphere and lower thermosphere (MLT) can be studied as the SuperDARN radars act effectively as meteor radars at near ranges. However, SuperDARN meteor echo measurements from all heights have typically been combined together to give a height-averaged picture of large-scale characteristics and dynamics of the MLT. This is in part due to the uncertainty in the measurement of individual meteor echo heights, which is in turn partly due to the lack of reliable (and for some radars, the lack of any) interferometric information. Here, we present a method for calibrating SuperDARN interferometer data which reduces the systematic offsets in meteor echo height estimations. Using 9 years of SuperDARN data we then determine occurrence distributions of SuperDARN meteor echo heights. The distributions are approximately Gaussian with height, extending from ∼75 to ~125km and peaking around ~102-103km. In addition, we investigate whether the Doppler spectral width measured by the SuperDARN radars, which is related to the ambipolar diffusion coefficient for meteor echoes, can be used as a proxy measurement for meteor echo height. Due to the large spread of spectral width measurements at any one height we conclude that this proxy measurement is not practical and that the height of individual SuperDARN meteor echoes cannot be estimated without interferometric information. We also discuss how more accurate height information could be used to study the height variation of neutral wind velocities and the ambipolar diffusion coefficient across the MLT altitude range, and conclude that SuperDARN meteor echo observations have the potential to complement, and significantly extend the altitude range of, meteor echo observations from standard VHF meteor radars.
Yesterday, oddball rocker St. Vincent (a.k.a. Annie Clark) joined popular music radio personality Annie Mac‘s show on BBC Radio 1 from Maida Vale Studios in London for a special acoustic performance. The radio spot in support of her new album, MASSEDUCTION, which was released to positive reviews this past Friday.St. Vincent Shares New Single, “Pills,” Ft. Kamasi Washington, Jenny Lewis, & More [Stream]After welcoming the idiosyncratic St. Vincent to the show and joking about their shared first name, Mac invited Clark to perform her first of three songs, a beautifully stripped-down guitar-and-voice rendition of haunting single “Los Ageless.” “This song was haunting me,” she explains about her first song, ‘Los Ageless,’ “The [melody] popped into my head a year ago and I thought ‘oh this is real good, I hope it’s not taken.’ And I rushed back to L.A. to get it recorded.”From there, the two speak about Clark’s songwriting process for the new album, her touring schedule, which Mac remarks looks quite extensive, but Clark informs her is “me taking it easy.” She also spoke about taking inspiration from New York City (where she’s lived for a decade) and the greats like Lou Reed, Patti Smith, and David Bowie that walked the East Village streets before her before playing her second acoustic original, “New York.”Finally, St. Vincent closes the radio spot with an acoustic rendition of The Clash‘s iconic anthem “London Calling,” to which she lends her striking and enthusiastically other personal flare. As she explains, “There’s a little band called The Clash, and they have a little song called ‘London Calling,’ and I’m going to play that one for you.”You can listen to full audio of St. Vincent’s appearance on Annie Mac’s BBC Radio 1 show below:Stream MASSEDUCTION in its entirety below via Spotify:[h/t – Pitchfork]

If you Google “Bill,” the first hit you get is the phrase “Bill me later.” It’s an accidental tribute to the writer-turned-activist whom everyone calls by his first name: Bill McKibben ’82, who spoke at Harvard Tuesday.McKibben’s message for years has been that oil-based economies shelve the issue of the environmental costs of fossil fuels. When it comes to the natural systems that support humanity — clean air, fresh water, and pristine seas — the message from developing countries has been: Bill me later.Well, the bill is due, McKibben said, and it may be too late to pay. Seas are rising, temperatures climbing, storms intensifying, and floods and droughts worsening because of fossil fuel emissions, a statement with a 95 percent chance of certainty, according to the Intergovernmental Panel on Climate Change, up from 66 percent in 2001.“At the moment, physics is well ahead” of political action, McKibben told a crowd at Sanders Theatre, but the fight is on. There have been growing protests — many of them centered on the controversial Keystone XL pipeline — and a new movement to persuade institutions to jettison investments related to fossil fuels.“What a strange pleasure it is,” McKibben said, to be in the tiered seating, polished wood, and stained glass venue that he remembered from lectures in his undergraduate days. McKibben delivered the annual Robert C. Cobb Sr. Memorial Lecture, sponsored by the Harvard Institute for Learning in Retirement, an arm of the Division of Continuing Education since 1977.“My goal is to bring at least some of you out of retirement” and into a life of climate-change activism, said McKibben. That shift may even mean getting sent to jail, a life event the author endured for the first time in 2011 during a protest at the White House. Since then, he has talked with eager new older activists. “This is on my bucket list,” one told him. “Tell me how I can get arrested.”Young people are leading climate change activism now, said McKibben, but it’s time to see “elders acting like elders” by putting their comfort on the line for a cause. “If you’re going to be arrested, please wear a necktie or a dress,” he told the audience, since those are visual signals that “there is nothing radical going on here.”“Radicals work at oil companies,” he said, because the radical consequences of oil-slicked climate change are “burning the top of the Earth, melting Arctic ice, acidifying the oceans. What could be more radical than that?”At the beginning of the lecture, which was delivered in a witty and extemporaneous style, McKibben offered an apology. “My role in life is basically to be a professional bummer-outer,” he said, an activist delivering stark facts, in this case on “the prettiest fall day of the year.”But he promised to get past the worst of the talk first and fast, saying that: the Earth has just come out of 10,000 years of mild climate in the Holocene epoch and into an uncertain era of climate change; storms, wildfires, droughts, and temperatures are breaking records at a rat-a-tat pace; oceans are turning acidic; 80 percent of the Arctic ice cover was gone last summer; and in a few decades “we’ve taken one of the most basic features of the Earth [steady temperatures] and broken it.”The Earth’s temperature has risen about 1.6 degrees Fahrenheit in the last few decades, which may not sound like much, since it’s about three-quarters of a watt per square meter of the Earth’s surface, the equivalent of a Christmas tree bulb. But taken worldwide, said the author, that extra heat equals the output of “400,000 Hiroshima-size bombs daily.”He sketched one consequence: Each degree of temperature rise worldwide means a 10 percent cut in grain yields.McKibben pointed to events of the past week as signs of the changing climate: forest fires in the West, catastrophic flooding in Colorado, a typhoon ripping into Japan, and rare double storms that punched both coasts of Mexico.The signs are there for all to see, he said, even closer to Boston. “The New York City subway filled up with the Atlantic Ocean last October,” he said of Hurricane Sandy. “What more do you want? And we are only at the start — only at the start — of our global warming era,” which some analysts say will make present-day civilization impossible.McKibben summed up the surprise and fear of climate change, saying, “This is by far the biggest thing human beings have ever done.”After his look at the grim facts, he turned to solutions. He said that putting a price on carbon use would assure that greenhouse gases don’t just “pour into the atmosphere for free.”More large-scale renewable energy projects would reduce reliance on fossil fuels. Germany is a success story in that respect, he said, with solar and wind power arrays that some days this summer provided half of that nation’s electricity. “Not many people go to Germany for their sun-splashed vacations,” McKibben said, pointing to the plausibility of renewable energy even in unlikely places. “There are more solar panels in Bavaria than the United States.”In the future, he said, societies should get a boost from distributed-generation energy systems, the small-scale, decentralized power supplies that reduce vulnerability and emphasize regional resilience. (He predicted that nuclear power will play a very small part in backing away from climate change, since such plants are too slow to get on line, and too expensive for debt-crushed times.)He suggested that building a climate-change movement could lead to the large-scale civil alliances and actions that could prove a counterweight to a moribund Congress.McKibben discussed 350.org, the global movement that he and seven undergraduates started at Middlebury College in Vermont, where he is the Schumann Distinguished Scholar. (The number refers to 350 ppm, or parts per million, the amount of carbon dioxide in the atmosphere that was a scientific tipping point for climate change. That number is now over 400 ppm.) “Our goal was to organize the world,” he said to a patter of laughter. The group’s first global action rippled across the globe, with 5,200 demonstrations in 181 countries.More global actions followed, and participants provided thousands of pictures from around the world. McKibben displayed some of them on a screen. Many showed what he called the most common activists in the world, who are young, poor, brown, black, and Asian. Some of the demonstrations were huge. Others were small, like one in Les Cayes, a seaport in southwestern Haiti. In the picture, seven children with signs stand ankle-deep in a flooded street.That small demonstration argued that “your actions affect me,” said McKibben, reminding the audience that the poor in remote nations affected by climate change rely on the rich in developed nations to take action. “They can’t get to the White House to protest,” he said.McKibben will be in Washington, D.C., Saturday for a “draw the line” action, a coast-to-coast protest against the proposed Keystone XL tar sands oil pipeline.That pipeline is the outward sign of an environmental disaster already underway in Canada. With only 3 percent of the tar sands oil extracted so far in Alberta, he said that the ground-stripping oil mining has already disturbed a section of boreal forest the size of Scotland and created vast pools of tailings waste held back by the biggest dams in the world.His lecture came on the official publication day of his latest book, “Oil and Honey,” a memoir of his transition from journalism to activism. (Its subtitle is “The Education of an Unlikely Activist.”)The “oil” of the title is the symbol of his public fight, largely through 350.org, against the coal, gas, and oil industries. The “honey” is the book’s emotional antipode, recounting McKibben’s periodic visits with Kirk Webster, a Vermont neighbor who runs a small-scale, chemical-free beekeeping operation.“His life doesn’t seem Luddite or retro. It seems advanced,” wrote McKibben, who says that regional, self-sufficient economies can buffer the effects of climate change. He called Webster, who doesn’t own a computer and writes with pencil and paper, “a solid human being, attractively and somewhat dauntingly solid.”McKibben is a creature of two worlds, the calm of home in Vermont, with its rhythms as natural as a beekeeper’s seasons, and the rush of an activist’s life, with its 400 emails a day, 24-hour news cycle, and constant world travel that he admits leaves vapor trails of spent fossil fuels behind him.The book was not the point of coming to Harvard, McKibben said, and he barely mentioned it, though his lecture bore the same title. But in response to a question, the book came up. He called his friend’s honey operation a sign of the “beautiful, evolving local economies” that are rebounding in an age marked by the resurgence of small farms and the popularity of farmers markets, the food sector’s fasting-growing segment.But then the “bummer-outer” McKibben came back, in discussing the alternate farm and energy sector. “By itself, it’s not enough. We have to work at the global (level), and we have to work at the local.”At the end, McKibben pointed again to the joys of the fall day still in full splendor outside. But for him there was work yet to do. As the departing audience streamed past, McKibben stood outside Sanders, head down, reading the screen on his cellphone.
Michael Yu | The Observer Professor emeritus of history George Marsden gave a lecture entitled “Beyond Liberalism and Culture Wars: A More Inclusive Pluralism,” followed by panel responses by two Notre Dame professors on Friday.Speaking in the first installment of the Professors for Lunch talks sponsored by the Potenziani Minor in Constitutional Studies, Marsden described the development of American religious culture over the last several decades.Beginning in the 1950s, there was a gradual movement away from mainstream American Protestantism, Marsden said.“Religion was important in American culture, but until [the 1950s], the religion that was accepted was Protestantism,” he said. “So there was religion in the public life, but it also privileged one tradition at the expense of others.”Further diminishing Protestantism’s role in mainstream culture, Marsden said, was the rise of the counter-culture movement in the 1960s.“The counter-culture movement challenged the predominantly white Anglo-Saxon Protestant establishment,” he said. “Many of the mainstream Protestant denominations took that to heart, and there was a rapid moving away from any distinctly sectarian dimensions.”During the 1970s, both the idea that religion was a private matter and the assumption that secularized values would replace traditional ones gained acceptance in mainstream culture, Marsden said.In subsequent decades, Marsden said a growing religious right has proposed to reverse the absence of religion in public culture but has fallen short.“Ultimately, the proposals tend to be simplistic … and center around restoring Judeo-Christian consensus,” he said. “So, in effect, what the right is doing is proposing something like the golden former Protestant establishment.“These sorts of proposals then lead to the standoffs of the culture wars. The secularists want privatization. … From the right, there are more and more strident demands that society needs to go back to conservative Protestantism.”Marsden said no major religious group in America presents a compelling theory on religious pluralism, but tolerance of religious diversity nonetheless needs to be cultivated.In proposing a solution to religious intolerance, Marsden cited Abraham Kuyper, a 19th-century Dutch statesmen, who proposed “to look to a tradition that makes religious pluralism into a principle … the tradition which is today principled pluralism.”“He argued that healthy societies ought to cultivate religious difference,” he said.The government, Marsden said, should recognize the rights of religious communities “to maintain their own institutions, associations of charitable works and schools free from ideologically-based regulation.”“If American life is healthier by honoring the diversity that we have … there should be an equal honoring of religious diversity,” he said.History professor Mark Noll said in response there were three factors in American society that prevented the implementation of a Kuyperian religious pluralism: electoral exclusion, educational exclusion and subverted subsidiarity — a move away from decentralization.“America’s two-party political tradition … makes it very difficult to produce the kind of pluralism that would diffuse the culture wars … that we have experienced over the last 30 years,” Noll said.He said public school education contributes to making religious pluralism untenable in American society.“The American public school system has always been hegemonic, discriminatory, homogenizing,” Noll said. “On the other side, it’s also the most celebrated icon of democracy, freedom and the American way.”Noll said subverted subsidiarity, the third factor barring the promotion of religious pluralism, stemmed from the success of the civil rights movements applied too extensively in addressing local issues.“The civil rights movement became the unthinking modern paradigm and exemplar of all forms of public ethics,” he said. “This is rhetoric out of control because it looks to the expansion of central government power as the remedy for local ills and disagreements.”Philosophy professor John O’Callaghan spoke last on the panel.Although some scholars believe religious pluralism is a post-modern development, the pluralism that both Kuyper and Marsden advocate for is actually a “pre-modern” belief founded on Augustinian principles, O’Callaghan said.“Augustine distinguishes two different senses of belief,” he said. “There’s the belief that such and such is the case. We might call this belief in a fact. But the other belief that is arguably more important for Augustine is the sense in which we say ‘I believe you.’ That’s believing a person. And, for Augustine, it is that sort of believing a person that makes believing a fact the starting point of understanding.”O’Callaghan said a Kuyperian religious pluralism, based on Augustine’s philosophical tenets, seeks to learn more from others based on the assumption that one does not know.“That is the origin for Augustine,” he said. “The thought that it is standing in relation to others who know what we do not know that we come to know and understand what we do not otherwise know and understand.”Tags: history, Kuyper, Marsden, Potenziani Minor in Constitutional Studies, Professors for Lunch, Protestantism, religion

Vermont Chamber of Commerce to Release the 2007/2008 Legislative Report CardDuane Marsh, President and Mike Belyea, Legislative Director at the Vermont Chamber of Commerce, will hold a press conference Wednesday September 10, 2008, to release its 2007/2008 Legislative Report Card. The conference will begin at 10 am in the Cedar Creek Room at the State House.This biennium, the Chamber’s Government Affairs Committee selected and scored 13 votes in the Senate and 14 votes in the house. The purpose of the Legislative Report Card is to clearly and succinctly depict the positions of Vermont’s 180 legislators on important business issues. The Vermont Chamber works closely with members of all political parties to champion legislation that will help businesses prosper and stay in Vermont.According to Duane Marsh, “We have found that many of our issues, the business communities, are the same issues facing all Vermonters – property taxes, roads and bridges, healthcare, and the cost of living within the state. With the current economic climate, it is even more important that business owners and all Vermonters understand how their legislators voted on the issues that affect their daily life.”
Here we are back in the thick of the fantastic Spring weather we all enjoy so much. We are eager to get out in these Appalachian hills on early afternoons and make a break for the trail head at dawn come Saturday morning. What kind of adventure are you up for and what should you carry in that day pack? If I am heading up a blue line for some wild trout we can come to a decision quickly. How about a couple of Boone Barrs to snack on, plenty of water and my tenkara kit. That is all there is to it.Living near Grandfather Mountain outside of Boone, NC, I find myself out on the trail sniffing for wild trout often. It doesn’t take much to find an access point and slip down into the shin deep waters that are flowing off of the tallest peak on the Blue Ridge Parkway. Some of the cascades and short falls create the perfect pools to angle for the rainbows, browns and brookies that hang tight to the side of these mountains. All I need to spend an afternoon with them is my tenkara rod, a line and a few flies. This setup is ultra-lightweight and packs down to nothing. This carbon fiber telescopic rods collapses down to twenty one inches and weighs a mere two and a half ounces. A small tin of flies and some 5X tippet counts up another ounce. A second spool of longer line and hemostats round this up to about five or six ounces. You can’t do much better for an afternoon of fishing in such a small package. The light pack weight and small size make it easy to manage on the trail. The long rod and equal length line offers a casting range up to twenty two feet or so. That is plenty of distance to make the precision casts needed to drop your fly of a fishes nose. The long reach rod lets you keep your distance so as to not spook the fish, which is always a plus when chasing high country wild ones. That extra length also is a key part of the tenkara style, which keeps line off the water. This eliminates water disturbance and prevents mending issues. Remember also, there is little need to carry a heavy fly box with four hundred choices in it. Grab a small tin and put one dozen standards in it and another dozen non-descript buggy flies. You’ll find that these fish eat them all just the same. Here is another thing to think about, two of these tenkara fly fishing kits weight less than a twelve ounce bottle of water. So you can carry two rods, two lines and share a tins of flies with a friend with no impact what-so-ever to your afternoon pack weight. What a great way to spread your day on the trail with the people you enjoy. Remember, it is impossible to catch and fish and not smile. So share a smile with someone this weekend.— By Jason Sparks of Appalachian Tenkara Anglers
By Dialogo April 14, 2009 Buenos Aires, April 13 (EFE) – The herbicide used in transgenic soybeans, Argentina’s main crop, can cause neuronal, intestinal, and heart malformations, according to scientific research released today. While the study “used amphibian embryos,” the results “are fully comparable to what would happen with the development of the human embryo,” professor of embryology Andres Carrasco, one of the authors of the paper, told Efe. “What is remarkable is that there are no studies on embryos at the global level, and much less in injecting glyphosate into embryos,” said the researcher of the National Scientific and Technical Research Council (CONICET) and director of the Laboratory of Molecular Embryology. The doses of herbicide used in the study “were far below levels used in spraying,” so the situation “is much more serious” because “glyphosate does not decompose,” he warned. Each year Argentina uses between 180 and 200 million liters of glyphosate, which was developed by the multinational company Monsanto, and which, since its arrival in the country in 1997, has been used on 18 million hectares of land. Carrasco said that the investigation found that “pure glyphosate at doses lower than those used in fumigation generates malformations” and “could interfere with various normal mechanisms of embryonic development that control how the cells divide and die.” “The companies say that drinking a glass of glyphosate is healthier than drinking a glass of milk, but the reality is that we have used as guinea pigs,” he added. He cited as an example: Ituzaingó, a neighborhood of 5,000 people on the outskirts of Cordoba (center), where in the last eight years there were approximately 300 cases of cancer associated with the spraying of pesticides. “In towns like Ituzaingó it’s too late, but you need a preventive system, to require companies to adhere to all security measures, and above all to have very strict standards for fumigation, which no one abides by, due to either ignorance or greed,” he said. The researcher also said that, beyond the work in which he participated, “a serious study must be conducted” on the effects of glyphosate on humans, and remarked that “for this matter, the State has all the resources.” Due to the barrage of legal claims related to the disproportionate use of agrochemicals in the cultivation of GM soybeans, in February the Ministry of Health established a group to investigate the problem in four Argentine provinces. Argentina is the third largest exporter of soybeans and also occupies a high rank in the global trade in derivatives (oils and meals) of that grain.
Senior judge pens Timucuan novel October 1, 2005 Regular News Senior Judge Fredric M. Hitt has written a historical novel, Wekiva Winter, detailing the struggles of the Timucua Indians of Florida and South Georgia to survive the European onslaught of the 1500s.“Too much spare time is a dangerous thing,” he said, referring to the two and a half years he spent researching and writing his book.Upon his retirement, Judge Hitt built a home on the St. Johns River in Volusia County. Close by, archaeologists were exploring an Indian midden containing artifacts dating back 10,000 years.“It was a startling revelation to realize that people lived along this river 8,000 years before the time of Christ,” he said.An amateur historian, Judge Hitt’s curiosity was further piqued by the six-foot-tall carving of a wooden owl that was discovered in the mucky bottom of the river by a drag-line operator in 1955. It is reputed to be the largest single-figure aboriginal carving in the Western Hemisphere. Two similar carvings were found nearby in the 1970s.“I asked myself, ‘Who were the people who could use primitive tools and produce such beautiful art?’ and ‘Why would the carvings end up in the river?’ I did my research, and I guess you could say that the rest is history,” he said.Judge Hitt has published short stories and articles about the St. Johns River, its history and ecology. This is his first full-length novel.Here is a synopsis: “Five priests are dead, brutally murdered by the people God had sent them to this dark land to save. One survived, the young Franciscan who was enslaved and tortured by the Indians, but who has refused to testify against the killers. And what of the old Indian, the Acueran, who speaks many tongues? Does he allow himself to be held prisoner of the Spanish sergeant? Is Father Pareja wise to use the old man in his studies of the Timucuan language? And what danger does he present for the priest, the mission, and the young altar boy, Juan de Coya? And what hope is there, if any, for the Indians who have no defense against the arquebus and musket, and no medicine for the pox and plague the invaders have brought with them? The year is 1602. The place is the Mission San Juan del Puerto, where the ancient Timucuan River of the Sun flows into an uncertain future.”Judge Hitt retired as a Seminole County judge in 2001, and now serves as a senior judge in the Seventh, Ninth, and 18th circuits in both circuit and county courts. Wekiva Winter is available on the Internet at Virtualbookworm.com (the publisher) and at Amazon.com and BarnesandNoble.com. The soft cover version sells for $15.95 and the hard cover edition is priced at $24.95.Judge Hitt hopes the book will be on bookstore shelves before the Christmas rush.
