Regular patterns in frictional resistance of ice-stream beds seen by surface data inversion

first_imgFast-flowing glaciers and ice streams are pathways for ice discharge from the interior of the Antarctic Ice Sheet to ice shelves, at rates controlled by conditions at the ice-bed interface. Using recently compiled high-resolution data sets and a standard inverse method, we computed basal shear stress distributions beneath Pine Island and Thwaites Glaciers, which are currently losing mass at an accelerating rate. The inversions reveal the presence of rib-like patterns of very high basal shear stress embedded within much larger areas with zero basal shear stress. Their colocation with highs in the gradient of hydraulic potential suggests that subglacial water may control the evolution of these high shear stress ribs, potentially causing migration of the grounding line by changes in basal resistance in its vicinity.last_img read more

American Hospital Ship to Support Philippines

first_img November 14, 2013 Back to overview,Home naval-today American Hospital Ship to Support Philippines American Hospital Ship to Support Philippines Adm. Harry B. Harris Jr., commander of the U.S. Pacific Fleet, directed the activation of the hospital ship USNS Mercy (T-AH 19) Nov. 13 to be ready to support ongoing disaster relief efforts in the Philippines in the wake of Typhoon Haiyan.Berthed in San Diego, USNS Mercy has been in a reduced operating status, which is normal for a hospital ship. Harris’ activation order accelerates Mercy’s ability to attain full operating status to include moving necessary personnel and equipment to the ship.If ordered to deploy, Mercy would get underway in the next several days and could arrive in the Philippines sometime in December, joining other U.S. Pacific Fleet units already supporting Operation Damayan.On Nov. 11 Secretary of Defense Chuck Hagel ordered the aircraft carrier USS George Washington (CVN 73) and her escort ships to depart early from a liberty port in Hong Kong and make best possible speed for the Philippines. George Washington, USS Antietam (CG 54), USS Cowpens (CG 63) and USNS Yukon (T-AO-202) will arrive off the coast of the Philippines the evening of Nov. 14 local time.U.S. Pacific Fleet ships already operating in the Western Pacific were also immediately diverted. USS Mustin (DDG 89), USS Lassen (DDG 82), USS Emory S. Land (AS 39), and USNS Bowditch (T-AGS 62) are now on station and coordinating with the Philippine government. The U.S. Navy also has P-3 maritime aircraft already supporting the disaster relief effort led by the Government of the Philippines.The amphibious ships USS Ashland (LSD 48) and USS Germantown (LSD 42) are departing Sasebo, Japan, Nov. 14 local time. After picking up Marines, equipment and relief supplies in Okinawa, the two ships will arrive at the Philippines in approximately one week. USS McCampbell (DDG 85) and USNS Charles Drew (T-AKE 10) are also heading to the Philippines.This collection of ships and their complement of aircraft, to include much-needed helicopters, will provide food and water, the capability to move relief supplies to isolated areas, and to help move the badly injured for medical care.The U.S. Navy persistently trains with numerous Pacific nations and military units, including the Armed Forces of the Philippines, to prepare for humanitarian assistance and disaster relief missions. In 2012, Mercy participated in the annual Pacific Partnership mission, which included working with Philippine authorities in the vicinity of Tacloban, the area hardest hit by Typhoon Haiyan. Because of the long-standing partnership between the two nations, the U.S., working through the Philippine government, is able to rapidly respond with critically needed capabilities and supplies in times of crisis.The role of U.S. military forces during any foreign humanitarian assistance event is to rapidly respond to host nations’ requests for support to help mitigate human suffering, prevent further loss of life and mitigate property damage. The U.S. Navy-Marine Corps team has a particularly successful history of working with international relief organizations and host nations to respond to natural disasters.Operation Damayan is part of the broader U.S. Government effort to support the Government of the Philippines’s request for humanitarian assistance. This joint team effort includes coordination by the U.S. Department of State and U.S. Agency for International Development, in constant consultation with Philippine authorities. To date, Philippine and U.S. personnel have transported more than 107,000 pounds of relief supplies.[mappress]Press Release, November 14, 2013; Image: US Navy Share this articlelast_img read more

Oxford students pay comparatively less in rent

first_imgFigures released by StuRents, a website listing student accommodation prices across the UK, reveal that Oxford students pay 32.63 per cent less for privately rented accommodation when compared to local residents.The analysis looked at 25,572 student properties across the UK, and collated the data to compare whether or not students are paying a premium on housing, when compared to non-student renters. The average cost of privately rented accommodation in Oxford for students is es- timated to be £102.50 per person per week. In comparison, the overall average rent for non-students in equivalent accommodation per week is £152.15. This places Oxford second in StuRents’ ranking of the differences between student and non-student accommodation rent values. The only university city where this dif- ference was greater was Reading. The study also found that there was a regional discrepancy between students who pay a premium for rented accommodation, and those who pay comparatively less. Whilst students renting in several cities in the north of the country, such as Loughborough, Durham, and Lincoln, pay premiums of up to 36.08 per cent, students living in cit- ies in the south of England have discounted accommodation compared to the average cost of renting in these areas. Speaking on these regional discrepancies, Tom Walker, the CEO of StuRents, stated, “Analysis of StuRents’ rental data has unveiled a new side to regional variances in the student housing market, indicating that the crown for the most expensive city on a stu- dent rental basis is by no means clear-cut. Clearly value is relative, so comparing inter-city student rental prices purely on an abso- lute basis is perhaps a little one-dimensional. “The most fascinating outcome of StuRents’ in-house research is that the story of the most expensive student towns, as defined by which towns have the highest average per-person-per-week rent, is incomplete. “In towns and cities where the mainstream rental market suffers from upwards pressure as a result of a burgeoning demand from young professionals and out-of-reach house prices, the student rental sector seems to trade at a discount to the market average. “Conversely, the general consensus in the northern half of England seems to be that students represent a more premium demographic, and rental prices are adjusted upwards to accommodate this.” Councillor Bob Price told Cherwell, “Rents in the private sector in Oxford are amongst the highest in the country and often provide poor value for money for the quality of the accommodation.”“The Council’s licensing policy for HMOs [Housing in Multiple Occupation] has seen significant improvements across the sector, but the lack of housing in the city and the high demand for it is continuing to increase rents and drive growth in the size of the pri- vate rented sector. “High rents are making it increasingly difficult for the Council to acquire accommodation for families accepted as homeless, resulting in a number of referrals out of the city.”last_img read more

Pitt Rivers to restore Maasai artefacts

first_imgIn Britain and France, there are laws which prevent museums from releasing objects, which had been stolen from formerly subjected people. In January, seven representatives of the Maasai came to Oxford at the invitation of Laura van Broekhoven, director of the Pitt Rivers, and InsightShare, to determine where and when the objects were taken. Two treaties in 1904 and 1911 reduced Maasai lands in Kenya by 60 per cent when the British evicted them in favour of settler ranches. More land was further taken for the creation of wildlife reserves and national parks, including Serengeti National Park. In a press release, the Pitt Rivers Museum said: “The visit, bringing one of the largest cross-national delegations of Maasai leaders to the UK, is a continuation and elaboration of the last visit, leading on to the next steps of the conversation and allowing for ceremonial and spiritual guidance by the elders.” Among the delegation was Lemaron Ole Parit, a spiritual leader with mystical powers. Out of 188 artefacts, Mr ole Parit identified give he thinks are “culturally sensitive enough to warrant a return.” The Maasai are an indigenous group from Kenya and northern Tanzania, with a reported population of around two million in total. A group of Maasai tribespeople visited Oxford this month as part of an effort to retrieve sacred objects held by the Pitt Rivers Museum. The Maasai visit came after Samwel Nangira, a Maasai from Tanzania, visited the Pitt Rivers when he was at a conference. This is part of the Living Cultures project which works to represent the history and narratives behind artefacts held in museum collections, relating the impact of the colonial past to the present. Starting in 2017, Living Cultures is a partnership between Maasai representatives from Tanzania and Kenya, the Pitt Rivers Museum and InsightShare.center_img On his visit, he questioned the labels attributed to some of the objects in the museum: “what does ‘collected’ mean? Like when you find something in a forest, so not donated, and not robbed?” InsightShare, an Oxford-based NGO, has worked with indigenous communities for over 20 years. The Pitt Rivers Museum said in a statement: “Museums are bearers of difficult histories and their collections are continued causes of pain for affected communities. By working together to reimagine these museums as spaces in which reconciliation might be able to come about, we believe that anthropology museums, like anthropology itself, can become anti-racist projects and sites of conscience.” In 2017, Emmanuel Macron said that he wanted to see the return of artefacts to Africa within five years. This contrasts with the usual defensive position taken by former colonial powers. Since Macron’s statement, the movement for restitution has grown. While several museums in the UK are constrained by the legislation that binds national collections, Universities are not. The Pitt Rivers Museum is contacting indigenous peoples directly about restoring articles. Oxford’s Pitt Rivers Museum, which holds the university’s archaeological and anthropological collections, has returned 28 stolen objects thus far, all of them human remains. Artefacts are especially important to the Maasai because they represent the continuation of a dead person’s life. Amos Leuka, a member of the delegation, said: “If somebody dies, we treat the artefacts as equally as important as a dead body.”last_img read more

Jesus College announces Michael Sheen Bursary for Welsh students

first_imgJesus College has announced a new bursary scheme that will provide financial support for Welsh students. The bursary has been developed with actor and activist Michael Sheen, who is also financially supporting the bursary. The college has said that the bursary will be “based primarily on household income criteria”. It is described as an attempt to overcome the barrier of economic inequality faced by many Welsh students.The college is already engaged in access activities for Welsh students. Together with St Catherine’s College and New College, Jesus College takes part in Oxford Cymru, a consortium that seeks to improve university accessibility for Welsh students and works with the Welsh Government. Jesus College also offers the Seren Summer School which is open to Welsh school pupils. As a result of these outreach efforts, the college has found “a 55% increase in admissions from 2016-2020” of Welsh students.Jesus College Principal, Professor Sir Nigel Shadbolt, believes “the Michael Sheen Bursary will drive this work forward and demonstrates a continued commitment to providing access and equity for all. We are hugely grateful to Michael for this generous support, which will positively impact the lives and futures of some of our more disadvantaged Welsh students.”    Michael Sheen said: “it gives me great pleasure to use what resources I have to help young Welsh students of real potential get the opportunities for learning there that they deserve as much as anyone else.”“I hope that these bursaries not only make it possible for Welsh students to take advantage of the educational possibilities at Jesus but also help to encourage a sense of what is possible for young Welsh people generally.”Will Rumble, Jesus College JCR’s Access Representative, told Cherwell: “The Michael Sheen Bursary will provide much-needed support to Welsh students at Jesus. It will decrease the financial burden faced by far too many Welsh students at Oxford and will complement the wide range of access work organised by Jesus for Welsh secondary school students. The bursary will allow Welsh students to enjoy their student experience with fewer financial concerns than currently possible.”Applications for the first Michael Sheen bursaries will open in Michaelmas term 2021.Image Credit: Simon Q / CC BY-NC 2.020/4/21, 18:34 – Updated to include JCR comment.last_img read more

Longport Wins A.C. Classic; Ocean City Second

first_imgBy Lesley GrahamThe Ocean City Beach Patrol scored points in every event Friday evening at the Atlantic City Classic to secure a second place team finish overall. Longport, the defending South Jersey champions, won three out of the four events to take the team title, while host Atlantic City placed third.  The Atlantic City Classic consists of four events: a doubles row, swim, singles row and the newest addition, the rescue relay.Ocean City placed fourth in the doubles row. Ocean City’s Matt Garbutt and Paul Boardman have been fine-tuning their technique over the past couple of months to blend together their styles and strengths when it comes to the rowing event. Garbutt, a lieutenant on the patrol, has a storied history of rowing excellence. “I first raced out of town in 1996 – 23 years ago,” Garbutt recalled.When asked what keeps him coming back all these years later to race on Friday nights, Garbutt explained: “There isn’t much you can still do at 43 that you could do at 20, and I take a lot of pride in my ability to do just that.”Doubles crew Matt Garbutt and Paul Boardman of Ocean City find their rhythm at the start of the doubles race.In the swim, Frankie Brady, a seventh-year Ocean City lifeguard who sits on Waverly surfing beach, battled to a second place finish. Brady said the ocean conditions played into his favor in the swim.“I definitely enjoy ocean swimming more than pool swimming, because the waves definitely help me,” he said. “My expertise is in wave riding, and I caught a wave at the end to help propel me into second place.”   The third event was the singles row. Ocean City’s Kevin Perry got off to a quick start and rowed a good course to secure a second place finish. With the ocean churning out some swells on the evening, Perry was able to catch a wave, passing a few other South Jersey competitors on his way to second.The final event of the evening was the rescue relay. A relatively new addition to the Atlantic City Classic, the event is a sprint doubles row with one rower unclipping a rescue bag at a flag in the ocean, hauling it into the boat, rowing back in and then jumping out with the bag to sprint up the beach. Brothers Shanin (left) and Bryan Theiss of Ocean City run up the beach at the finish of the rescue relay race.Brothers Brian and Shanin Theiss took second place in the event, helping to keep Ocean City in the top three for the team finish. The Theiss brothers have combined for over 30 years of competing for not only the Ocean City Beach Patrol but also squads in San Diego and Florida.The desire to win is what keeps them coming back year after year. “We are very competitive. It’s in our blood,” Shanin Theiss said in a post-race interview.That competitive spirit runs deep through all the competitors for the Ocean City Beach Patrol, who will continue to train to prepare for the next set of races, representing their patrol with pride.  Ocean City’s Kevin Perry rides a wave to a second place finish.RACE RESULTS: Doubles Row:1st – Longport2nd – Upper Township3rd – Atlantic City4th – Ocean City (Paul Boardman and Matt Garbutt)5th – Wildwood Crest Swim:1st – Longport2nd – Ocean City (Frank Brady)3rd – Wildwood Crest4th – Atlantic City5th – Brigantine Singles Row:1st – Atlantic City2nd – Ocean City (Kevin Perry)3rd – Avalon4th – Brigantine5th – Longport Doubles Row Sprint Rescue:1st – Longport2nd – Ocean City (Bryan and Shanin Theiss)3rd – Atlantic City4th – Ventnor5th – Brigantine Overall Standings:1st – Longport (16 points)2nd – Ocean City (14 points)3rd – Atlantic City (13 points)4th – Upper Township (4 points – tiebreaker)5th – Wildwood Crest (4 points)OCBP’s Paul Boardman and Matt Garbutt at the start of the doubles row race (Photos courtesy Dale Braun)OCBP’s Kevin Perry at the start of the singles row race.OCBP brothers Bryan and Shanin Theiss at the start of the doubles row sprint rescue.OCBP’s Frank Brady comes in second in the swim race.OCBP’s Kevin Perry finishes second in the singles row. OCBP’s Bryan and Shanin Theiss place second in the doubles row sprint rescue race.

In the archives

first_imgAn American newspaper is qualifying for a monument from the housewives of the world. It has discovered, or calculated, that, in the course of a year, the average mother of four or five children makes the ’equivalent’ of 1,095 loaves of bread… 50 cakes and 750 pies. She also prepares meat which, if assembled, would make one or two cows and about six pigs, peels 5,100 potatoes, makes 1,200 beds and dusts on average 7,500 chairs every twelve-month. This sort of stuff makes one hungry for statistics. Cannot some baker come up with some intensely human story of the number of times a year his nose begins to itch as soon as he plunges his hand into the dough? If the trade should ever decide to answer its plague of critics, a wagon-load of distressing statistics of this kind would make the public weep oceans of tears. Really, bakers are a most unenterprising lot of fellows.last_img read more

Giving hybrids some respect

first_imgHarvard researchers are bringing new respectability to hybrids, showing that not all are evolutionary dead ends or short-lived mistakes and that some not only encompass the best traits of both parents, but create a unique mix that can endure as a separate species.Researchers at Harvard’s FAS Center for Systems Biology used genetic analysis to examine the evolutionary history of a recently recognized species of butterfly, the Appalachian tiger swallowtail, discovered in 2002. The Harvard analysis confirmed what other researchers had suspected, that the butterfly was a hybrid of the Canadian tiger swallowtail and the more southern eastern tiger swallowtail. Further, the researchers showed that the hybrid species originated when males from the Canadian species mated with females from the south.“Our work provides perhaps the first animal example that illustrates how hybrid species may be selectively favored when they inherit from their parent species-specific combinations of genes that underlie important ecological traits,” said Krushnamegh Kunte, a postdoctoral fellow at the center and lead author of the study, which was published online Sept. 8 in PLoS Genetics.The research shows that the species formed in a burst of hybridization that likely occurred during the last interglacial period. As the range of the cold-adapted Canadian tiger swallowtail retreated north with the glaciers, the range of the warm climate-adapted eastern tiger swallowtail advanced northward and up into the Appalachian Mountains. The two species subsequently intermingled in the mountains during a changing climate.The result is the Appalachian tiger swallowtail, which shares key traits of both parental species. Like the Canadian tiger swallowtail, it is tolerant of colder temperatures. And like the eastern tiger swallowtail, females have two forms, one that resembles the yellow, tiger-striped male, and a second dark-winged form that mimics the distantly related, poisonous pipevine swallowtail, a strategy that provides protection from predators.That combination of traits allowed the hybrids to populate the Appalachian Mountains, south of the range of the Canadian tiger swallowtail, overlapping with the pipevine swallowtail, and in territory cool enough to keep the eastern tiger swallowtail out.“This trait combination helped the new hybrids to occupy a novel niche that the parent species was unable to occupy. The hybrids eventually evolved into a new species,” said Kunte. “This is a nice example of natural selection driving the origin of species. In this case, the North American thermal landscape, historical climate change, and mimicry provided the ecological stage for the evolution of a new hybrid species.”The work was conducted by Kunte and Bauer Fellow Marcus Kronforst, the paper’s senior author, and a team of colleagues from the University of Texas, Austin, Princeton University, and Michigan State University.Creating species through hybridization is common in plants, but is rare in animals, Kronforst said. Though attitudes are changing, until recently, hybrids outside the plant kingdom were thought of as evolutionary mistakes. While their parents are adapted over millions of years to fit certain environmental niches, hybrids sharing traits from two species tend to be poorly adapted to survive in either parent’s niche. In addition, hybrids can have physical problems. Mules, for example, which are crosses between horses and donkeys, are sterile.The research, Kronforst said, enriches the picture of hybridization, illustrating that it is not merely a series of isolated accidents with little larger meaning, but rather an ongoing evolutionary process. Hybrids, Kronforst said, are a vehicle for the genetic mixing of parent populations. Sometimes the result is a less fit individual, and the impact on the larger population is negligible. Sometimes fertile hybrids result, and mate back with the parent species, providing an avenue for genetic exchange between parent species. In still other cases, Kronforst said, the hybridization can result in new species, mixing parental traits in a way that allows the offspring to inhabit their own environmental niche.“Hybridization has huge creative potential even in animals, where it is often disregarded,” Kronforst said. “Hybridization can drive the creation of new species.”last_img read more

Letters to the Editor for Thursday, Jan. 31

first_imgGazette article went too easy on KayRegarding your article about the resignation of NYRA chief Christopher Kay by Gazette reporter Stephen Williams: I read through the 26 paragraphs of plaudits and laudatory gushing and found exactly one single sentence about Kay’s apparent crime. No information about whether criminal charges would be filed, no mention of restitution or whether other employees would face discipline, no specifics about the apparent crime, no quotes from an eager district attorney. This article reads more like a resume than news about a crime.It’s a sad fact that our criminal justice system treats white collar crime more leniently, but it’s truly disheartening to see The Gazette do so also. James Van DijkSaratoga Springs Sending your child to a private school is a financial investment, but it’s an investment in your child’s future. Personally, I can’t put a price on the happiness and fulfillment my daughter receives from her private school. Jennifer VanDeCarrBallston Lake Consider private school for your kidsI’d like to urge parents who are concerned about bullying, class size and general apathy in public schools to consider private schools. My daughter is quiet and reserved, and when it came time to send her to kindergarten, I was concerned she would fall through the cracks in public school. We selected St. Mary’s school in Ballston Spa, the “small school with the big heart,” and we couldn’t be happier with our choice. The teachers at St. Mary’s appreciate the uniqueness of each child and encourage each child’s God given talents and gifts to flourish. The class sizes are small, allowing the teachers to focus on the individual needs of each child. A small class size helps eliminate bullying, because the students really get to know each other and learn to work together as a team. Knowing your classmates on a personal level breaks down barriers. It teaches students to show patience and understanding toward each other.  Trump proves his unfitness for officeArticle II, Section One, of the U.S. Constitution specifies a mere 35 words in the presidential oath of office, to wit, “I do solemnly swear that I will faithfully execute the Office of President of the United States, and will to the best of my ability, preserve, protect and defend the Constitution of the United States.” Forty-four presidents have recited this oath, with Donald Trump the latest, in January 2017. Sadly, it’s now clear that Trump has egregiously violated this solemn oath in just two short years.Exhibit one is the growing evidence of a conspiracy between Trump’s key advisers and campaign officials and the Russian government to subvert our democracy in the 2016 presidential election. Thirty-four individuals, including six key Trump advisers, have either been indicted or pleaded guilty in the special counsel investigation. Overwhelming evidence is building of Trump’s own obstruction of justice in this probe. His confounding embrace of Russian President Vladimir Putin has its roots in his dogged pursuit of riches and his 30-year infatuation with building in Russia. In short, Trump has put his and his company’s financial interests above the interests of the United States.Couple this conduct with Trump’s staggering degree of mendacity, over 8,100 false and misleading statements in two years, his populating the cabinet with grifters and unethical individuals, his embrace of foreign autocrats, his stunning lack of intellectual curiosity or desire to learn, and his laziness and inattentiveness to the job. The picture it paints is stark: Trump is singularly unfit for office.Dennis J.
