Martian polar expeditions: problems and solutions

first_imgThe Martianpolar ice caps are regions of substantial scientific interest, being the most dynamic regions of Mars. They are volatile sinks and thus closely linked to Martian climatic conditions. Because of their scale and the precedent set by the past history of polar exploration on Earth, it is likely that an age of polar exploration will emerge on the surface of Mars after the establishment of a capable support structure at lower latitudes. Expeditions might be launched either from a lower latitude base camp or from a human-tended polar base. Based on previously presented expeditionary routes to the Martian poles, in this paper a “spiral in–spiral out” unsupported transpolar assault on the Martian north geographical pole is used as a Reference expedition to propose new types of equipment for the human polar exploration of Mars. Martianpolar “ball” tents and “hover” modifications to the Nansen sledge for sledging on CO2-containing water ice substrates under low atmospheric pressures are suggested as elements for the success of these endeavours. Other challenges faced by these expeditions are quantitatively and qualitatively addressed.last_img read more

Academics condemn “repressive” Counter-Terrorism Bill

first_imgOxford professors have joined 500 academics in signing an open letter published in The Guardian that condemned the Counter Terrorism and Security Bill currently being debated in parliament.The letter, which included signatures from Oxford academics, declares that the bill would be “a threat to freedom of speech at Universities”, as well as “an unlawful and unenforceable duty on educational institutions and staff .”The controversial bill, which seeks to curb campus extremism as one of its aims, has caused considerable debate, both within Oxford University and on the national stage. The letter declares, “One of the purposes of post-compulsory education is to foster critical thinking in staff , students, and society more widely. Our universities and colleges are centres for debate and open discussion, where received wisdom can be challenged and controversial ideas put forward in the spirit of academic endeavour.“The best response to acts of terror against UK civilians is to maintain and defend an open, democratic society in which discriminatory behaviour of any kind is eff ectively challenged. Ensuring colleges and universities can continue to debate difficult and unpopular issues is a vital part of this.”After branding the “draconian crackdown” as both “unnecessary” and “ill-conceived”, the academics called on the government to reconsider attempts to tackle extremism in the UK that do not compromise academic freedom.One of the signatories, Oxford academic Professor Robin Cohen, a former Director of the International Migration Institute, told Cherwell, “One of the odious provisions is that visiting speakers will be required to submit their presentations two weeks in advance. This is a basic violation of academic freedom. Academics are not automata. They think and develop their ideas as they go.“It is an even more horrible thought that Oxford academics will be obliged to report external speakers who have views considered to be advocating ‘non-violent extremism’ and who are thought to challenge democracy and individual liberty.”With regards to the legislation, Oxford University commented, “Individual academics from Oxford have already made it clear that they have concerns about the Bill. The University is monitoring events with interest.”The Home Office told Cherwell, “We must ensure that poisonous, divisive ideologies are not allowed to spread, including through our universities.“There is no contradiction between promoting freedom of speech and safeguarding the interests and well-being of students, staff and the wider community. Universities UK already provides guidance to help institutions develop extremist speaker policies.“The measures in the Bill will build on these existing arrangements and ensure Prevent is delivered to a consistent standard across the country. This is particularly important in areas where terrorism is of the most concern but we are clear that all areas need to understand the local threat and take action to address it.”last_img read more

Thompson wins writing grant

first_imgHarvard Review Editor Christina Thompson has been awarded a Creative Writing Fellowship in Prose by the National Endowment for the Arts (NEA). Thompson was one of 42 nonfiction and prose writers chosen from an applicant pool of about 1,000. The award carries a $25,000 stipend.Thompson’s work-in-progress explores the history of Polynesian people and how they came to inhabit the Pacific region. Thompson, who grew up in Boston, became enamored with the area while studying in Australia on a graduate school fellowship. She enrolled as a doctoral student at the University of Melbourne and, on a trip to New Zealand, met Seven, a Maori man who would become her husband. Their relationship is prominently featured in her book, “Come On Shore and We Will Kill and Eat You All,” a historical memoir that inspects interactions between Westerners and Maoris.“This new project takes off from a chapter in that book called ‘Hawaiki,’ and goes back in time to recount the ancient Polynesian colonization of remote Oceania,” said Thompson.Thompson received a grant from the Literature Board of Australia in November — more funding that, along with the award from the NEA, will enable her to travel alongside her husband and sons to conduct research in far-flung places like Vanuatu, Tonga, New Zealand, Australia, and French Polynesia. “We’re hoping to visit a couple of archaeological sites and get to some of the more out-of-the-way islands, including an atoll or two.”“The NEA fellowship is a very lucky break for me because I’ve been wanting to write this book for a few years,” said Thompson. “I can do a large part of the background research right here in Widener [Library], but when it comes to getting the feeling of the places — the color of the sky, the feel of the air, the temperature of the water — there is really no substitute for getting your feet in the sand.”Thompson’s work has appeared widely in publications such as Vogue, American Scholar, the Journal of Pacific History, and Australian Literary Studies, and in the 1999, 2000, and 2006 editions of Best Australian Essays. She has been the editor of Harvard Review since 2000, and teaches creative writing courses at Harvard Extension School, where she won the James E. Conway Excellence in Teaching Writing Award in 2008.last_img read more

Music for a better world

first_imgMusic entertains, but it also can fuel hope and happiness.So it did on Saturday, when the Harlem Gospel Choir celebrated the life and legacy of Martin Luther King Jr. at the annual Joyful Noise gospel concert at Sanders Theatre.“I want 2013 to be the year that we, all of us … dedicate ourselves to building a community of mutual respect and kindness,” said Shelley Neill, the executive director of the Cambridge Multicultural Arts Center, which has staged the concert for 26 years.“If there is one single message among all the messages that Dr. King left behind, it would be to take heart and put it in practice to help build a community based on mutual respect.”Neill, who in the past has opened the festivities with children’s stories or tape recordings of King’s speeches, this year began the concert with her own powerful, a capella rendition of “You Gotta Move” by the blues artist Mississippi Fred McDowell. The packed house of nearly 900 came in on the chorus, “When the Lord gets ready / You Gotta Move,” and kept time by stamping their feet on the floor to create the sound of marching.The song was dedicated to the late Will Hills, a former Arts Center board member who had passionately supported the concert and whose family and friends helped make it an annual event, and John and Terri Traverso, the tour manager and production manager of the Harlem Gospel Choir.Neill then turned the stage over to the Harlem Gospel Choir, just returned from a month in China. Neill said the New York-based group was founded in 1986 by Allen Bailey after he attended a celebration to honor King; it has since performed for Barack Obama, Nelson Mandela and Pope John Paul II, with the stated mission of “bringing people and nations together and giving back.” This year marked the seventh time the group has sung the Joyful Noise concert.The choir’s nine vocalists, keyboard player, drummer, and bassist performed “Total Praise” to mark their return to America, then launched into a set that included many of the songs popularized by Whitney Houston. The crowd enthusiastically participated when invited, singing along to “The Greatest Love of All” and “I Go to the Rock,” which became a resonant call and response, with sopranos, altos, basses, and tenors standing and singing in turn until all were on their feet. And at Houston’s best-known recording, “I Will Always Love You,” the choir received a standing ovation.When the group finally left the stage, the house lights came up — and nobody left. Rather, the audience stood firm and clapped and cheered and cried for more music. The choir returned and sang a moving “We Are the World” to a delighted and grateful crowd.The evening was co-sponsored by the Center and Harvard’s Office of Government, Community and Public Affairs and the Cambridge Multicultural Arts Center, with help from the Massachusetts Cultural Council, the city of Cambridge, the Boston Phoenix, the Bay State Banner, and the East Coast Grill.last_img read more

A higher plane

first_imgHere’s a short geometry test: How many straight lines can be drawn connecting two points on a flat plane? If you make two angles on a triangle smaller, does the third get larger or smaller? If you split a square diagonally, are the two resulting triangles the same size or different?If the answers — for the record, one, larger, and the same — seem obvious, they should be. The questions are examples of the innate understanding of abstract geometry that all humans possess, even if they’ve never studied the subject. For researchers, however, the question is: Where does that knowledge come from?The answer, say Harvard scientists in Elizabeth Spelke’s Laboratory for Developmental Studies, may lie deep in our evolutionary history.Previous research has shown that young children and animals use geometric information in similar ways — to navigate environment and to recognize shapes. In a study published last month in the Proceedings of the National Academy of Sciences, researchers presented evidence that young children rely on the same abilities when exercising uniquely human abstract geometric skills, such as reading maps. The results suggest the innate understanding of abstract geometry among humans has origins in the evolutionary past.“There are two possibilities for the origins of this human-specific innate understanding of geometry,” said graduate student Moira Dillon, the first author on the study. “One is that it’s something that’s completely new to humans; it’s something we’ve arrived at through our complex cognitive development. The other possibility is that it derives from existing geometric skills we’ve inherited from other animals.”Researchers in earlier studies were able to show that animals possess two basic geometric abilities: the ability to use distance and directional information to navigate their world, and the ability to use angle and length information to recognize shapes.Using tests similar to those used with other animals, as well as tests specifically designed to tap into young children’s ability to read geometric maps, Dillon and her colleagues showed that children use the geometric abilities shared with other animals to understand uniquely human spatial symbols.Previous tests, Dillon said, demonstrated that children as young as 2½ could relate the abstract geometry in a map to the real world, but it was unclear how. The new work revealed that young children, unlike animals, can flexibly use their geometric sensitivities — to distance and direction or to angle and length — to read maps.“What we knew is that children — just like animals — use distance and directional information to navigate, and angle and length information to recognize shapes,” Dillon said. “What we now see is that children — unlike animals — can use one or the other type of geometric information flexibly when reading spatial symbols like maps, depending on what information is available to them in the environment.”To uncover these intuitions and understand their origins, Dillon and her colleagues started by building two triangular rooms in the lab. One included only the sides of the triangle, with the corners removed, while the other included only the triangle’s corners, with the sides removed.Children were presented with a map of the full triangle, and were asked to place a stuffed animal at a location marked by a dot.“What we found was that children were relying either on their ability to navigate or their ability to recognize shapes,” Dillon said. “If they were presented with a room that only had sides, they used the distance information to navigate, and when they were presented with a room that only had corners, they used the angle information they use to recognize shapes.”Although young children showed flexibility in their use of geometry when reading maps, there were still limitations: They were unable to relate the two geometric sensitivities to each other. Dillon said previous research has shown that by about age 12, children begin to integrate these two geometric sensitivities — relating distance information to angle information. Older children and adults therefore achieve the sort of abstract geometric knowledge that has long puzzled researchers.“Adults, because they have a more advanced, mature abstract representation of geometry, can use both types of information at the same time,” she said. “But because those intuitions are fully developed, it’s difficult to look at adults and understand their origins.”The challenge for researchers now is to understand how the ability to use geometry for navigation and shape recognition come together to form our abstract innate knowledge about the points, lines, and figures on the Euclidean plane.“We have to figure out what happens between age 4 and age 12,” Dillon said. “How do we get from this incredible early ability to use symbolic geometry in maps to the later-developing, very abstract ability to reason about points and lines and the behavior of triangles when they’re manipulated? We think we know now where these intuitions come from, but we’re not sure how they come together.”last_img read more

Dinner aims to spark dialogue during fourth annual Women’s Week

first_imgStudents and faculty gathered Wednesday night for the Celebration of Women Dinner, as part of Women’s Week, which is sponsored by Shades of Ebony and the Gender Relations Center (GRC). Rachel Wallace, president of Shades of Ebony, said in her welcoming remarks that she is proud of how much Women’s Week, now in its fourth year, has grown.“When I was just a freshman, I remembered upperclassmen asking us to help them with an idea they had, and they wanted to celebrate women and 40 years of women at Notre Dame,” she said. “We started out with the GRC doing three events in the spring of 2013, and this year, we have six events. We’ve really come a long way.” According to Wallace, the Women’s Week theme reflects the theme for National Women’s Month; this year, the theme is “Working to Form a More Perfect Union: Honoring Women in Public Service and Government.” The dinner featured Kym Worthy, the current prosecutor from Wayne County, Michigan, as the keynote speaker.Worthy, who graduated from Notre Dame Law School in 1984, is known for filing charges against former Detroit Mayor Kwame Kilpatrick and for working on a massive backlog of unprocessed rape kits. Despite these high-profile cases, she said she never intended to be a prosecutor. “At that time, there weren’t very many female prosecutors at all,” Worthy said. “There weren’t many women, there certainly weren’t many people of color in the office — they kind of had the same view I had at the time, a skewed view that prosecutors were there to put African Americans in jail. That’s not true, but perception is reality for most people.”Much of Worthy’s work has been devoted to domestic abuse, sexual assault and other women’s issues. According to her, these issues need to be addressed more fully. “Why can we only be a more perfect union by paying attention to so-called ‘women’s issues?’ Because they’re exactly the issues we aren’t addressing,” she said. “And I feel they wouldn’t be ignored if it weren’t primarily female victims.” In 2009, 11,000 abandoned unprocessed rape kits were found in a Detroit Police Warehouse. Worthy said it was extremely difficult to get funding from the city to test the kits and carry out prosecutions, if possible. “Nobody was interested. Nobody wanted to help,” she said. “The police department wanted it to go away — it wasn’t on their watch. They didn’t care that it represented 11,000 victims.”Some of the rape kits dated back 35 years, according to Worthy. She said while some women use the kits to make sure they’re not pregnant or have any STDs, most victims do it because they want justice. “Women do it because they want to find their perpetrator,” Worthy said. “So, can you imagine finding out that, not only were you assaulted, not only did you go through that rape kit process, but that rape kit sat on a shelf for 30 years and nobody did anything about it?” In order to form a more perfect union, Worthy said the country needs to stop neglecting women’s issues, because they affect everyone. “We have to break the domestic abuse cycle,” she said. “We have to break the sexual assault cycle. We have to look at sexual assault in a different way — it’s the forgotten crime, no one really cares about it. If we want to have a more perfect union, we have to reexamine these issues, and it has to start with prosecutors.”Tags: Gender Relations Center, GRC, Kym Worthy, Shades of Ebony, Women’s Weeklast_img read more

09 Plum good!

first_imgBy Kathryn Taylor University of Georgia Volume XXVIII Number 1 Page 9 Plums are popular for cooking and jam making, and many people enjoy them fresh as well. The sweeter varieties are some of the most delicious dessert fruits we have.Plum varietyGardeners can choose among several varieties.”Methley,” a small but sweet early-season variety, is self-fertile and crops reliably. “Morris” is a commercial plum that’s productive and firmer.Two Auburn releases, “AU Rubrum” and “AU Producer,” produce reliably. And several Georgia releases, like “Spring Satin” (a plum-apricot hybrid), the yellow-fleshed “Byrongold” or the tasty “Rubysweet,” are good for fresh eating.Many gardeners prefer plums that are best when eaten green, like “Bruce,” “Six Weeks,” “Robusto” or “Segundo.”Whatever you choose, you need at least two plum varieties for pollination and fruitfulness, since plums are generally not self-fertile.When considering other varieties, choose trees recommended for zones 7 or 8. A good, central Web site that lists fruit tree nurseries is Several Tennessee nurseries sell plum trees appropriate to the Southeast.Grow them most anywherePlums will grow all over the country but often flower early, making them vulnerable to spring frosts. In the home garden or landscape, proper placement can reduce the vulnerability of the fruit and flowers to frost.Placing plum trees next to a wall can protect against cold winds, mitigate temperature inversions and allow heat storage. Placing them on a grade, too, allows cold air to drain into lower areas, providing protection on frosty nights.Another trick some gardeners use is to keep outdoor Christmas lights on fruit trees to protect them on cold nights.Soil results importantA well-drained, sandy-loam soil at a pH of 6.5 is ideal for growing plums. It’s best to have the soil checked before you plant.The test will tell how much lime and phosphorus to add to the soil before planting. Work these into the soil throughout the rooting depth — generally, 18-24 inches will be enough.Don’t add any fertilizer to the planting hole. Do this later. In the first and second years, add 1 pound of 10-10-10 in March and 1.5 cups of calcium nitrate in May and July. Thereafter, apply two-thirds cup of calcium nitrate each March and August Be careful not to place the fertilizer against the tree’s bark.Tree formationImmediately after planting a 30-inch, one-year-old tree in February or March, cut it off at 18 to 24 inches to force bud break of lower buds.Then, during the summer, select about four that are at a 25- to 30-degree angle from the vertical, forming the framework for a “bowl” or “vase.” The ultimate shape of the tree depends on its growth habit.Plum trees have forms ranging from spreading to upright and need to be pruned with the natural pattern in mind. Prune the upright type to spreading limbs and the spreading type to more upright limbs. These will become the scaffolds that will bear fruit close to the trunk, keeping it in easy reach for harvest.last_img read more

Champlain College students conduct market research on the Marketplace

first_imgBURLINGTON, Vt.–Some Champlain College students have been hitting the bricks of the Church Street Marketplace, but this time they arent shopping. Students in Champlains Consumer Behavior course this semester are working with five businesses on the Marketplace to complete store-specific marketing research.This is the second semester to feature such projects, which bring clipboard-carrying Marketing and Business students to the pedestrian marketplace. Last spring students worked with eight businesses on Church Street, while others conducted research for Church Street Marketplaces director Ron Redmond.It had been difficult to acquire market research because of our budget restrictions, said Marketplace director Ron Redmond. Champlain College students answered our call.The data is helpful–it tells us where our strengths and weaknesses are. What we had been doing before was relying on anecdotal information, he said. This gave us a much better read on our markets, Redmond said.This semester the students are verbally surveying store customers about things such as name recognition, customer service, reasons for visiting, and shopping habits.The student teams met with store managers to define each stores objectives and designed a project plan and questionnaire. Theyll implement the market research and analyze the responses. Theyll then deliver to these businesses a written report including findings, methodology used, relevance of data and recommendations for each store. While the businesses earn valuable market research that can be acted upon, the students will gain priceless hands-on experience.Professor Michael Miceli said, Doing a project like this helps students put theory into practice, while providing valuable information for store owners that, upon implementation, will have an immediate positive impact on their business.Area businesses and nonprofits looking for assistance to tackle business challenges and opportunities are encouraged to check out the resources available through Champlain College at is external).last_img read more
