Dynamical processes involved in the retreat of marine ice sheets

first_imgMarine ice sheets with mechanics described by the shallow-ice approximation by definition do not couple mechanically with the shelf. Such ice sheets are known to have neutral equilibria. We consider the implications of this for their dynamics and in particular for mechanisms which promote marine ice-sheet retreat. The removal of ice-shelf buttressing leading to enhanced flow in grounded ice is discounted as a significant influence on mechanical grounds. Sea-level rise leading to reduced effective pressures under ice streams is shown to be a feasible mechanism for producing postglacial West Antarctic ice-sheet retreat but is inconsistent with borehole evidence. Warming thins the ice sheet by reducing the average viscosity but does not lead to grounding-line retreat. Internal oscillations either specified or generated via a MacAyeal-Payne thermal mechanism promote migration. This is a noise-induced drift phenomenon stemming from the neutral equilibrium property of marine ice sheets. This migration occurs at quite slow rates, but these are sufficiently large to have possibly played a role in the dynamics of the West Antarctic ice sheet after the glacial maximum. Numerical experiments suggest that it is generally true that while significant changes in thickness can be caused by spatially uniform changes, spatial variability coupled with dynamical variability is needed to cause margin movement.last_img read more

The Bagel Group bought out of administration

first_imgLondon-based manufacturer The Bagel Group, which filed for administration earlier this month, has been sold to a new company, Mr Bagel’s Limited, as a going concern. The business has been acquired by the Mansouri family for an undisclosed sum. According to a statement released by the new company, the purchase has been backed by Kevin Mansouri, who has appointed previous MD of The Bagel Group, Paul Kahalani, as a consultant adviser to the business.Under the terms of the acquisition, the business and other assets were sold to Mr Bagel’s Ltd on 28 January, according to administrator MCR Corporate Restructuring.Paul Williams, partner at administrators MCR, said it had been able to preserve “the majority of jobs in the company”. According to the Mansouri’s, the business is seen as “an exciting opportunity for growth”, and it will look towards offering a “broader range of food products” such as confectionery.Paul Kahalani said: “I believe the new plans will enable the company to accelerate the growth of the business.” He added that the company is also hoping to expand its employment requirements soon.Kevin Mansouri said he was “excited” to be backing the acquisition and sees signficant growth opportunities.The company, previously known as Mr Bagels plc, reportedly produces around 150 million bagels a year under its Mr Bagel’s and Natural Bagel brands, supplying the retail and foodservice markets.The Bagel Group hit national headlines in December after alleging an executive at rival Maple Leaf Foods was involved in attempted price-fixing, an allegation that is still under investigation. Mr Bagel’s Limited was registered at Companies House on 13 January 2009.last_img read more

Bread tastes to be formally assessed

first_imgA newly formed association, the National Organisation of Bread Tasters, is due to attend the SIAB exhibition in Italy from 22-26 May next year, where it will reveal plans for courses on the sensory assessment of bread.Founded by Walter Cricrì, an agronomist and sensorial analyst, and formed in conjunction with the Richemont Club Italy, the organisation plans to approach bread-tasting in a similar way to that of cheese, wine and olive oil.Aimed at consumers, bakers and caterers in Italy, regional courses will train people to become expert bread tasters, able to recognise, identify and evaluate the sensory qualities of bread, such as aromas, flavours and textures. “The first step,” Cricrì said, “will be to standardise the terminology used when assessing bread.”last_img read more

Harvard establishes research alliance with Tata companies

first_imgHarvard University has established a six-year, $8.4 million research alliance with a group of Tata companies including Tata Sons, Tata Communications, Tata Steel, and Jaguar Land Rover. Building on close connections between Harvard’s engineering and business Schools, the first-of-its-kind initiative adds a new leadership-development component to the University’s research partnerships.Under an agreement coordinated by Harvard’s Office of Technology Development (OTD), the collaboration will support cutting-edge research in labs across the University, while also providing professional development programs to visiting technology business leaders. The unique combination of research funding and executive education is designed to help position Harvard’s research innovations to bring the greatest benefit to the public worldwide.“This initiative will harness the power of research that crosses traditional academic boundaries, leading to more rapid discovery and the development of new products and services that address real-world problems,” said Harvard Provost Alan M. Garber.To accelerate the development of novel technologies and create a future generation of entrepreneurial leaders, the agreement establishes a Tata Fellowship Program at Harvard Business School (HBS). For each research project funded under the alliance, an experienced Tata employee will have the opportunity to spend up to a year in residency at Harvard in the HBS Executive Education Program. Nominated by the Tata senior leadership and subject to Executive Education admissions standards, Tata Fellows will benefit from the insight and guidance of an assigned HBS faculty mentor and gain the educational foundation to foster “intrapreneurship” within the Tata companies. They will also each collaborate with a Harvard research team to develop a commercialization plan for technologies that may arise from the funded projects.“Harvard has highly productive strategic alliances with several industry partners that support research on campus, in disciplines such as biomedical science, materials science, and chemistry. This initiative brings a new dimension that will include new links with Harvard Business School,” Garber said. “With its strengths in both science and business, Harvard is well positioned to succeed with this creative and integrated program.”The initial focus of the research alliance will be on robotics, wearable technologies, and the “Internet of things” (IoT), tapping into recent strides in the field of advanced materials. Over time, the scope could broaden to encompass new research areas of mutual interest. The arrangement with Tata is expected to stimulate a global exchange of ideas.“Non-U.S. executives account for close to two-thirds of the senior business leaders in our open-enrollment programs held in our classrooms in Boston, Shanghai, and Mumbai,” said Das Narayandas, senior associate dean for HBS external relations and publishing and Edsel Bryant Ford Professor of Business Administration. “Harvard Business School faculty routinely develop and lead custom programs for marquee global clients around the world, introducing business leaders to the newest innovations and research in the areas of strategic thinking, change management, and leadership, among others.”Gopichand Katragadda, group chief technology officer for Tata Sons, said, “We are excited about forming this research collaboration between Tata and Harvard that will uniquely encompass engineering, management, and other disciplines to produce market outcomes. The Tata Group companies have pioneered products and services in diverse areas, including materials, automotive, telecommunications, and information technology. The Tata Fellows will bring deep market understanding in these areas for successful deployment of the advanced research at Harvard.”The funded projects, which have yet to be selected, will advance scientific research in labs across the University, including at the Faculty of Arts and Sciences, the Harvard John A. Paulson School of Engineering and Applied Sciences, the Wyss Institute for Biologically Inspired Engineering, Harvard Medical School, and the Harvard T.H. Chan School of Public Health. A joint steering committee will guide the overall direction of the research alliance and approve funding for the proposed projects.“In many ways this exciting alliance foreshadows the type of close interactions we anticipate between HBS, Harvard Paulson School, and our corporate partners as the much-anticipated Science and Engineering Complex and the enterprise research campus take shape in Allston,” said Isaac T. Kohlberg, Harvard’s senior associate provost and chief technology development officer. “We’re glad to be expanding Harvard’s range of corporate partnerships and eager to welcome the Tata Fellows into the thriving entrepreneurial ecosystem of Cambridge and Boston.”last_img read more

Clever crows

first_img A study of YouTube star Snowball the cockatoo suggests humans may not be the only ones who can groove to a beat Study suggests they both understood the phenomenon and had uses for it It’s no secret crows are smart. They’re notorious for frustrating attempts to keep them from tearing into garbage cans; more telling, however, is that they are one of the few animals known to make tools.But would you believe doing it actually makes them happy?That’s the finding of a recent paper, co-authored by Dakota McCoy, a graduate student working in the lab of David Haig, George Putnam Professor of Biology, who found that crows behaved more optimistically after using tools. The study is described in an Aug. 19 paper in Current Biology.“What this suggests is that, just the same way we enjoy something like solving a crossword, they actually enjoyed simply using a tool,” McCoy said. “I think it suggests there’s a lot more going on in that little head than we think. They get satisfaction out of doing things they’re good at, have trained for their whole lives, and that they use frequently.”While tool use in the animal kingdom is not unheard of — chimps use sticks to “fish” for termites and other animals use rocks to smash open nuts or shells — New Caledonian crows stand out for manufacturing multiple complex tools and regularly refining their designs.But how can making and using tools make an animal feel good? A clue, McCoy said, lies in looking at how complex actions make humans feel.“I think we tend to under-anthropomorphize animals, especially really intelligent animals,” she said. “It’s not that they are machines, and we are feeling beings. Clearly, animals also have emotional reactions and moods.”,And, one of those emotions is the pleasure of accomplishment.“One potential answer for why tool use evolved is because crows are used to picking up objects and caching them,” she said. “They actually love, when you’re experimenting with them, to pick up your equipment and cache it way up high where you can’t get it.”Once crows started using tools, she said, the fact that it made them feel good encouraged them to keep at it, refining and developing the behavior further.“Maybe crows are just like humans and other primates in that, when they’re doing these complicated actions, they’re reinforced not just by getting a prize out of it, but because they actually enjoy the process itself,” she said.To understand how crows felt about using tools, McCoy and colleagues devised an experiment to test how optimistic the birds were feeling.“We do have subtle ways to test mood, and the classic paradigm is a glass half filled with water,” she said. “Someone who is feeling pessimistic will interpret it as half empty, while an optimistic person will see it as half full.”For the crows, researchers conceived a similar test.In the lab, crows were trained using a small box. When placed on the left side of a table, the box always contained a large reward — three pieces of meat. On the right side, it contained just a scrap of meat, a far smaller reward.Once the crows understood the difference, researchers placed the box in the middle of the table. If the birds quickly came to investigate that ambiguous box, it suggested they were optimistic that they would find a large reward. If they waited or didn’t visit the box at all, it suggested they were more pessimistic.,To test how they felt about tool use, the crows were then put through a series of tests over a number of days — one in which they had to use a tool to extract a piece of meat from a box and another in which the meat was readily available.“But we thought that it might not be that tool use puts them in a good mood, it could be just that they had to work harder,” McCoy said. “So we [added] two more conditions. In one the meat was right on the table so there was no effort involved, and in another “effortful” condition, they had to fly around to the four corners of the room to retrieve each piece of meat.”The results, she said, showed that, following tool use, the birds were much quicker to approach the ambiguous box, and much less enthusiastic after the effortful test compared to the easy test.“They enjoyed the easy condition, that was no surprise,” McCoy said. “But the surprise was that, clearly, they don’t just like tool use because it’s difficult. We controlled for difficulty and that wasn’t what was motivating their interest — there is something specific about tool use they’re enjoying.” So you think he can dance?

A red oak live tweets climate change Could open the door to new bioactive healing strategies As water temperatures increase, so does risk of exposure to toxic methylmercury While it’s impossible to say for certain exactly what the birds were feeling, McCoy said her study is far from the first to attempt to gauge what effects animals’ moods.“Many people have done studies about what kind of mood animals are in … but the research to date has almost exclusively been on captive animals, and what kind of circumstantial changes can improve their mood,” she said. “Many people have shown that animals’ mood improves if you do something like give them a larger cage, but this study shows that animals also have a better mood if you give them complex, fun tasks to do.”McCoy, who is a student in the Graduate School of Arts and Sciences, said that she hopes to see the findings of the study applied to improving the lives of animals in captivity.“Our findings suggest that one way to improve the welfare of captive animals is to give them complex, species-specific enrichment where they’re using skills they have … to achieve goals instead of just receiving passive enrichment,” she said. “We’re far from a world where we don’t have animals in captivity … but they could live a much more enriching life if they’re housed socially and given fun tasks to solve.”This research was supported with funding from the Department of Defense, Air Force Office of Scientific Research, National Defense Science and Engineering Graduate (NDSEG) Fellowship, a Theodore H. Ashford Graduate Fellowship, a Royal Society of New Zealand Rutherford Discovery Fellowship, a Prime Minister’s McDiarmid Emerging Scientist Prize, and the Max Planck Institute for the Science of Human History.
