Analyses of a 12 m marine sediment core from Neny Fjord, Marguerite Bay, Antarctic Peninsula (68.2571°S, 66.9617°W), yield a high-resolution record of Holocene climate variability. The sediments preserve signals of past glacial and marine environments and offer a unique insight into atmospheric and oceanic forcings on the western Antarctic Peninsula climate. Dating of basal material reveals that deglaciation of the fjord occurred prior to 9040 cal. yr BP and provides a minimum constraint on the timing of deglaciation close to the southern Antarctic Peninsula ice-divide. Continuous deposition of ice-distal sediments and seasonally open-water diatoms indicates that the site has not been over-ridden by glacier ice during the Holocene. A facies of sand-rich material offers the only evidence of a localized glacier advance, during the mid Holocene. Statistical analysis of diatom assemblage data reveals several climatic episodes of varying magnitude and duration. These include an early-Holocene warm period (~9000 and ~7000 cal. yr BP), potentially associated with influx of Circumpolar Deep Water onto the continental shelf and coinciding with widespread glacial retreat and Holocene collapse of the George VI Ice Shelf. The mid-Holocene (~7000 to ~2800 cal. yr BP) sediments are characterized by diatom assemblages indicative of less pervasive sea-ice cover and prolonged growing seasons with evidence of increased meltwater discharge from ~4000 cal. yr BP. The youngest sediments (~2800 cal. yr BP to present) contain a record that is consistent with the widely documented ‘neoglacial’ period followed by an abrupt reversal and climate amelioration from sometime after ~200 cal. yr BP.

Dear Editor,“A rose by a different name still smells the same”But spoils will always be spoils no matter what clever Orwellian word tries to replace it.(Reminiscent of Bush/ Cheney’s attempt to sanitize the ugliness of their invasion of Iraq based on lies by naming it ” Operation Enduring Freedom.”)On 3/1/2016 the Cape May Chamber of Commerce sponsored a conference which was very revealing of their ethics and integrity: How to change the publics’ perception of Dredge Spoils by the simple means of a name change.Words like crud, sludge or muck though accurate are not even being considered.No, the PR guys are seeking an upscale word change and seemed to have settled on ” resource.”The Merriam Webster Dictionary defines ” resource” as a place or thing of value. Try buying something with a bucket of muck. Good luck!!Sludge spoils from the Ocean City bay is filled with toxic chemicals. These are the by product of nearly 50 years of BL England polluting both air and water in their coal burning activities.Now the PR guys are trying to spray this toxic muck in a fine mist over the wetlands. What is the scientific basis for this? What possible unforeseen consequences? Clearly science is irrelevant to these PR guys empowered by their attempts at sowing seeds of confusion in the science of Climate Change.We are being confronted with the greatest threat to our existence especially living in shore communities by rising seas and sinking land. The question is not how to keep the yachters yachting lanes open by further degrading the wetlands but how do we minimize and prepare for the catastrophe that is heading our way.By spending millions and millions of dollars to dig out the dirt only to have the channels fill in a few years why not focus on the truly bigger issue of the main culprit to climate change. Extraction and burning of fossil fuel. Spend the money on renewable energy and the retraining of all the good workers from the coal and gas industries.The hour is late but there is still time to halt the march towards our own demise. No more gas transmission lines and no more gas plants in New Jersey.Sincerely yours,Steve Fenichel, MD
Companies and directors must be aware of their responsibility to file accounts with Companies House. Companies can sign up to receive e-mail reminders, which can be sent to up to four e-mail addresses. There will always be unforeseen events that mean a company is unable to file accounts on time. In exceptional circumstances, companies can request an extension to the filing deadline, however these requests must be received before the filing deadline. Most companies can file accounts electronically – it’s faster and easier. The Companies House WebFiling service has in-built checks to ensure that all the relevant information is provided before a customer can submit. It also provides filers with automatic e-mail confirmation that accounts have been received and once they have been accepted for filing. Bizarre filing excusesThe companies which gave these excuses received a late filing penalty and their appeals were unsuccessful. Penalties increase depending on how late the accounts are filed and the status of the company.Senior Enforcement Manager, Nick Parker, said: Read our guidance for general help and advice on filing company accounts.You can email [email protected] or call our contact centre on 0303 1234 500. We’re open 8.30am to 6.00pm, Monday to Friday. Each year we receive unusual excuses from directors who fail to file their company accounts on time.Some of the most outrageous reasons given include: To send us accounts electronically, you must register for our online filing services. When you register, we’ll send an authentication code in the post to your company’s registered office. “goats ate my accounts” “I found my wife in the bath with my accountant” “pirates stole my accounts” “we delivered the accounts to the betting office next door to Companies House” “a volcano erupted and prevented me from filing” “slugs ate my accounts” “it was Valentine’s Day” “my company was more successful than I thought it would be, so I was too busy to file” The authentication code can take 5 working days to arrive.
GBBO 2013 winner Frances Quinn has made a 4ft-wide version of a jaffa cake with Hambleton Bakery, which has broken the world record by over a foot.The record-breaking jaffa cake was nearly 23 times the size of the ones you find on supermarket shelves – the recipe included 120 eggs, six kg of butter and three litres of marmalade.Quinn teamed up with Hambleton Bakery for the challenge, at its base in West Bridgford, Nottinghamshire. Last week she announced the launch of a new range to be sold across its shops.She said: “I got the idea when there was a whole debate going on about whether jaffa cakes are biscuits or cakes.It really mattered to me as well, because I make a lot of jaffa cakes and if they were classed as biscuits, there would be more tax on them. But I decided to make the largest-ever one. I really wanted to break the record.It took a lot of planning. We actually had to bake it in six parts and then fit it all together, like a giant jigsaw.”She added that anyone who wanted orange jelly that day would have had no luck either, as she thought the team had bought the local stores out of it.Having baked the giant jaffa cake, Quinn had to transport it to London for its unveiling. She said getting it in and out of the van and then carrying it up a small flight of stairs in a pub was almost more of a challenge than making it.
A strong performance in bakery has bolstered slowing sales growth at Tesco, according to its latest trading update.The company today (13 June) reported that the category, along with dairy and fresh prepared foods, had delivered strong volume growth, with sales up 1.6%, 1.6% and 2.4%, respectively, in the 13 weeks ended 25 May 2019.Overall UK sales, meanwhile, saw like-for-like change of 0.4% – a marked slowdown on the 1.7% growth reported in the final quarter of 2018/19 and the 2.1% growth seen in the comparative quarter for that financial year.However, Tesco said it had outperformed its rivals in a “subdued” market. This followed further investments in its range, price and loyalty as part of its ‘100 Years of Great Value’ campaign.It also noted a strong performance during the Easter period across all formats, including its biggest-ever sales day for small stores on Easter Sunday, which fell on 21 April this year.UK online grocery sales were also up 7% year-on-year, with the proportion of customers choosing the click & collect option increasing to over 10%.“We have had a strong start to the year, growing ahead of the UK market on both a volume and value basis. Our customer offer is more competitive than ever, with a wider choice of our ‘Exclusively at Tesco’ products now available in more stores, helping to drive more than 10% sales growth across the range,” said Tesco chief executive Dave Lewis.
Researchers at the Harvard School of Engineering and Applied Sciences have developed a way for photographers and microscopists to create a 3-D image through a single lens, without moving the camera. This improbable-sounding technology relies only on computation and mathematics — no unusual hardware or fancy lenses. The effect is the equivalent of seeing a stereo image with one eye closed. Researchers at the Harvard School of Engineering and Applied Sciences (SEAS) have developed a way for photographers and microscopists to create a 3-D image through a single lens, without moving the camera.Published in the journal Optics Letters, this improbable-sounding technology relies only on computation and mathematics — no unusual hardware or fancy lenses. The effect is the equivalent of seeing a stereo image with one eye closed.That’s easier said than done, as principal investigator Kenneth B. Crozier, the John L. Loeb Associate Professor of the Natural Sciences, explains.“If you close one eye, depth perception becomes difficult. Your eye can focus on one thing or another, but unless you also move your head from side to side, it’s difficult to gain much sense of objects’ relative distances,” Crozier says. “If your viewpoint is fixed in one position, as a microscope would be, it’s a challenging problem.”Offering a workaround, Crozier and graduate student Antony Orth essentially compute how the image would look if it were taken from a different angle. To do this, they rely on the clues encoded within the rays of light entering the camera.“Arriving at each pixel, the light’s coming at a certain angle, and that contains important information,” explains Crozier. “Cameras have been developed with all kinds of new hardware — microlens arrays and absorbing masks — that can record the direction of the light, and that allows you to do some very interesting things, such as take a picture and focus it later, or change the perspective view. That’s great, but the question we asked was, can we get some of that functionality with a regular camera, without adding any extra hardware?”The key, they found, is inferring the angle of the light at each pixel, rather than directly measuring it (which standard image sensors and film would not be able to do). The team’s solution is to take two images from the same camera position but focused at different depths. The slight differences between these two images provide enough information for a computer to mathematically create a brand-new image as if the camera had been moved to one side.By stitching these two images together into an animation, Crozier and Orth provide a way for amateur photographers and microscopists alike to create the impression of a stereo image without the need for expensive hardware. They are calling their computational method light-field moment imaging — not to be confused with light-field cameras (like the Lytro), which achieve similar effects using high-end hardware rather than computational processing.Importantly, the technique offers a new and very accessible way to create 3-D images of translucent materials, such as biological tissues.Biologists can use a variety of tools to create 3-D optical images, including light-field microscopes, which are limited in terms of spatial resolution and are not yet commercially available; confocal microscopes, which are expensive; and a computational method called shape from focus, which uses a stack of images focused at different depths to identify the layer at which each object is most in focus. That’s less sophisticated than Crozier and Orth’s new technique because it makes no allowance for overlapping materials, such as a nucleus that might be visible through a cell membrane, or a sheet of tissue that’s folded over on itself. Stereo microscopes may be the most flexible and affordable option right now, but they still are not as common in laboratories as traditional, monocular microscopes.“This method devised by Orth and Crozier is an elegant solution to extract depth information with only a minimum of information from a sample,” says Conor L. Evans, an assistant professor at Harvard Medical School and an expert in biomedical imaging, who was not involved in the research. “Depth measurements in microscopy are usually made by taking many sequential images over a range of depths; the ability to glean depth information from only two images has the potential to accelerate the acquisition of digital microscopy data.”“As the method can be applied to any image pair, microscopists can readily add this approach to our toolkit,” Evans adds. “Moreover, as the computational method is relatively straightforward on modern computer hardware, the potential exists for real-time rendering of depth-resolved information, which will be a boon to microscopists who currently have to comb through large data sets to generate similar 3-D renders. I look forward to using their method in the future.”The new technology also suggests an alternative way to create 3-D movies for the big screen.“When you go to a 3-D movie, you can’t help but move your head to try to see around the 3-D image, but of course it’s not going to do anything because the stereo image depends on the glasses,” explains Orth, a Graduate School of Arts and Sciences Ph.D. student in applied physics. “Using light-field moment imaging, though, we’re creating the perspective-shifted images that you’d fundamentally need to make that work — and just from a regular camera. So maybe one day this will be a way to just use all of the existing cinematography hardware, and get rid of the glasses. With the right screen, you could play that back to the audience, and they could move their heads and feel like they’re actually there.”For the 3-D effect to be noticeable, the camera aperture must be wide enough to let in light from a wide range of angles so that the differences between the two images focused at different depths are distinct. However, while a cellphone camera proves too small (Orth tried it on his iPhone), a standard 50 mm lens on a single-lens reflex camera is more than adequate.Seeing depth through a single lens | Harvard School of Engineering and Applied Sciences
They may have different approaches — one wants to teach computers to “think” like humans, and by doing so unlock the secrets of how the brain works; the other is interested in economics and public policy — but both Ruth Fong ’15 and Benjamin Sprung-Keyser ’15 share a desire to improve the world around them.And their hopes were just given a major boost.Fong and Sprung-Keyser were among the 32 Americans named as Rhodes Scholars on Sunday. The scholarship, one of the most prestigious academic awards in the world, covers the full cost of two or three years’ study at the University of Oxford.Harvard has now produced a total of 350 Rhodes Scholars.Ruth Fong“I was pretty shocked when I found out,” Fong said. “I think it’s still sinking in, to be honest. The other finalists are all really remarkable, so I was really caught by surprise.”Fong’s interest in whether a computer could be taught to “think” like a human began an early age, when her first-grade teacher, Mrs. Sciacca, introduced her to the notion of context clues. By examining all the words in a sentence, Fong was able to guess what an omitted word might be.At Harvard, she became intrigued by the idea that a computer might learn to do the same.As a sophomore, the Mather House resident and computer science concentrator enrolled in a computational linguistics class, and worked on using algorithms to extract the meaning of single words from sentences using context clues. She later applied similar techniques to images.“I seek to develop a comprehensive understanding of learning,” she wrote in her Rhodes application. “Currently, I am developing techniques that utilize fMRI brain activity data to improve object detection algorithms. Some preliminary results demonstrate that context clues about how ‘animated’ an image is — that is, how likely it contains living things like humans or animals — can be extracted from fMRI data. These findings support my driving hypothesis that computers ‘learn’ better when they ‘think’ more like humans.”Fong plans to continue those studies at Oxford, where she will pursue degrees in both computer science and math and foundations in computer science.“I knew I was in love with computer science from a pretty early age,” she said. “I grew up playing with Legos and K’nex. Now is really a critical time for the field, but these questions are not new. We’re at the beginning of an era in which we finally have the computing resources to explore the question of what it would mean for a machine to think and be human-like.”Benjamin Sprung-Keyser“It’s been quite the whirlwind over the past 24 hours, but people have been so incredibly supportive … it’s just been fantastic,” Sprung-Keyser said.A large part of his interest in economics, he said, stems from the fact that he was introduced to the field during one of the most serious crises in recent memory, the Great Recession of 2007-09.“With millions displaced, I saw that the costs of unemployment are not just monetary; they are psychological,” he wrote in his scholarship application. “I saw that labor may be a necessity, but it is also a source of fulfillment — allowing individuals to impart meaning to their lives. I was drawn to the study of employment, and that has influenced nearly all my work.”Sprung-Keyser plans to pursue a master’s degree in economics at Oxford, with a goal of eventually obtaining a Ph.D. and conducting research on issues that lie at the intersection of economics and public policy.“There are some things about the subject of economics that are incredibly attractive to me,” the Kirkland House resident said. “It has a quantitative component to it that I find very interesting, but it also has a little bit of messiness of the real world as well. I can’t think of doing anything else.”His time at Oxford, however, may not be limited to study in his chosen field.With a strong background in debate, Sprung-Keyser said he is looking forward to taking part in discussions at the renowned Oxford Union.“That is perhaps the best place in the world to engage in debate,” he said. “It’s hard to know exactly what experience at Oxford will translate to the future, but you have to imagine if you have two years to study economics, conduct your own research, and participate in debates on public and social policy at the Oxford Union, that those things become important in the future, and they end up mattering.”
It’s unlikely that many of his grade-school classmates would have predicted that Sunn m’Cheaux would grow up to be a Harvard instructor.“I remember being humiliated in elementary school, because I sounded different from the other kids. I was a Gullah-speaking kid in an English-speaking class. I was a fish out of water,” the artist, activist, and social commentator told a roomful of Cambridge seventh-graders recently.“That memory has always stuck with me. Like that song [‘Let’s Call the Whole Thing Off”], ‘You say tomato’? Well, I said ‘demayda,’ not ‘tomahto,’ but I was corrected, disrespected, while the latter was accepted. Which is why I now teach Gullah at Harvard University, to see that Gullah is accepted and Gullah/Geechee people respected.”M’Cheaux, an instructor in the African Language Program at Harvard, worked with students at Vassal Lane Upper School in Cambridge, teaching them the origin of his native tongue.“The Gullah language is a creole, the result of essentially taking multiple existing languages and mashing them all up into one,” he said. “Mix in some other elements indigenous to the Sea Islands and surrounding areas, and you have a whole new language. That in a nutshell is Gullah.”Gullah, or Geechee, was created by enslaved people brought from West Africa to Charleston, S.C., who needed a common language to communicate. It allowed them to speak freely, by way of encoded speech, in the presence of those holding them in bondage. That code-speak evolved into a language of its own, indigenous to the Gullah Geechee Cultural Heritage Corridor, which extends along the coast of the southeastern U.S.M’Cheaux was working with the students through Harvard’s Project Teach program, which helps local seventh-graders see themselves as college-bound, showing them that college can be an affordable, accessible, and attainable opportunity. (Research out of the Harvard Graduate School of Education has shown that middle school is when students begin to envision themselves going — or not going — to college.) The program works to expose students to examples of some typical and some atypical courses, and acknowledges that college can be different things to different people.For m’Cheaux, this has been a lifelong journey. Born into a rural, impoverished family in Charleston, m’Cheaux didn’t learn to speak English until he was bused to another town midway through elementary school. Although he became fluent in his second language, he says he never strayed far from his Geechee roots.M’Cheaux is the first and so far only instructor of Gullah at Harvard. He says he’s honored and humbled to be here, but knows he carries the responsibility of sharing the language and history of his people to a broader audience. His lessons build upon the groundbreaking work that Harvard graduate Lorenzo Dow Turner, M.A. 1917, started decades ago.“We really want to encourage a student’s innate curiosity,” said Joan Matsalia, associate director of Public School Partnerships at Harvard. “We want to show them that the subjects many people end up studying in college aren’t necessarily the things they imagined they’d study. College has something for everyone. Sunn, and his course on Gullah, is a perfect example of how important it is to follow your area of interest. Get excited about what you’re curious about, and the rest will come.”According to m’Cheaux, “Gullah is an oratory language passed down by people who were not academics. The language came into existence from people who did not go to school. They were literally banned from going to school — and threatened with death if they were educated. But ultimately what ended up happening to get Gullah recognized was that an academic [Turner] did the research and broke it down to show its connections to African languages.”What Turner discovered about Gullah was that it wasn’t just broken English, nor a sign of unintelligence. “There is something quite intelligent happening here. Something complex happening here,” m’Cheaux said in summarizing Turner’s research.The origin may indeed be complex, but evidence of the language is far more prevalent than many realize. Students were surprised to learn that many common words or phrases are actually rooted in the Gullah language: yam (sweet potato), Bubba (brother), gumbo (okra). Georgia, home of the Sapelo Island Geechees, is nicknamed the Goober State for its mass production of peanuts — and guba (goober) is the Gullah/Geechee word for peanut.,Probably the most recognizable Gullah word is kumbaya. The song of the same name has spiritual origins, as it is a Gullah prayer. “Kumbaya” — or “come by here, my Lord, come by here” — was originally a “shout song” or “work holler” used as a meditation, a way for workers to mentally cope with the task at hand.“I thought it was really interesting that the language that we speak every day has so much Gullah influence in it,” said seventh-grader Eman Abdurezak. “I think it’s important that people are teaching about it because people need to be aware of and help preserve it. I really enjoyed singing ‘Kumbaya’ together, and learning about what it actually meant. I never knew.”“Ancestors who created the language were trying to not only communicate with words and ideas, but also trying to figure out how to preserve their sense of self,” said m’Cheaux. “That’s how Gullah came into existence.“Some among us feel like if we decode our language, teach Gullah to those who do not live it, it will be diluted or die,” he said. “Indeed, the entrance of outsiders has seldom been in our best interest. Still, I believe we Gullah/Geechee people are at a juncture where sharing our language, culture, and contributions with others is integral to keeping those things alive.”M’Cheaux said he was thrilled to be able to share his love of the language and its origins with the students, who learned and practiced saying Gullah phrases, and sang along to traditional Gullah songs.“I really want to encourage you all to be excellent in at least one thing. It doesn’t really matter what that thing is,” m’Cheaux said. “Learn how to balance a spoon on your nose … you’ll start thinking about how it’s on staying on your nose. Gravity? Weight distribution? Now suddenly you’re curious about physics.“You may not know that’s what it is at the time — but you will,” he said. “So, pick a thing and that thing will be a seed that grows. Your excellence is not something that needs to be defined by someone else. Be great at anything and that will open the door to everything.”
Related James Mathew, president of the Undergraduate Council, was “pleased that the policy is universal,” but expressed concern that SEM/UEM might not do enough for issues of equity. The UC had polled students March 22-23 about three models of grading: Universal Pass/Fail, Opt-In Pass/Fail, and Double A (A/A-), which was created by the student group Harvard For All.“There are concerns — the primary one being that UEM still puts students at risk of receiving a grade of Unsatisfactory. In a SEM C-minus versus Pass D-minus, the threshold is slightly more restrictive, and we have to think about how our most disadvantaged student will be affected. We’re counting on administration and faculty to look out for the students who are especially challenged during these already difficult times.”Cassandra Extavour, professor of Organismic and Evolutionary Biology and of Molecular and Cellular Biology, calls the policy “absolutely the right decision.”“Worry about specific grades during a global pandemic should be the least of anyone’s concerns,” she said. “And when students aren’t on our campus they have even greater disparity in access to learning resources than they do on campus.”Informally polling the students in her own two courses, Extavour said at least 25 percent knew or feared that being removed from campus would negatively impact their learning.“Pretending this is a normal situation is not facing reality. This is not a normal situation. The changes in the world because of the pandemic are going to be felt for a long, long time to come.”The College updated its list of FAQs for students with answers to questions about how the temporary policy would affect applications to fellowship programs, graduate and medical school, and promised support from advisers willing to reach out to schools unwilling to accept a SEM grade.Harvard Medical School, for example, has noted to applicants: “So that no applicants are disadvantaged by policy decisions made by their colleges/universities as a result of this unprecedented event, HMS will accept pass/fail grading for spring 2020 coursework provided it is the policy of the college/university to only award pass/fail grades.”Said Gay: “This grading policy better meets the needs of today, and I hope prepares us to face challenges to come as this situation continues to evolve.” Harvard College will adopt an Emergency Satisfactory/Emergency Unsatisfactory (SEM/UEM) grading policy for the spring semester, a shift announced Friday by Claudine Gay, Edgerley Family Dean of the Faculty of Arts and Sciences (FAS), in response to the coronavirus pandemic.“We of course remain committed to academic continuity, but we cannot proceed as if nothing has changed. Everything has changed,” said Gay in a letter to the FAS community, recognizing unanimous endorsement from Faculty Council.Peer institutions, such as Dartmouth, Stanford, Yale, Columbia, and the Massachusetts Institute of Technology , have moved to similar grading policies for their spring terms. Factoring equity as a prime motivator, Gay said: “[F]or some students the challenges have been more severe. Some have seen parent job losses, or have had to take over child care and other household responsibilities, as health care and other essential workers in their families continue to provide critical support or have become ill themselves. Those who relied on the public library for internet access are struggling to find other ways to join their classmates online, as public buildings are ordered closed. Students in a time zone 12 hours away from us are feeling remote and closed off by time, and by closed borders.”Gay acknowledged “not everyone will agree with this policy, and I have heard reasonable arguments on all sides.” She charged the Committee on Undergraduate Educational Policy (EPC), a standing committee of the Faculty, to develop a proposal to address the situation. EPC consulted widely with directors of undergraduate studies, received input from the Undergraduate Council (UC) and the Honor Council, consulted with peers and with graduate fellowship, and internship programs.In a follow-on message to all undergraduates, Amanda Claybaugh, dean of undergraduate education and Zemurray Stone Radcliffe Professor of English, said: “I’d like to thank all of you who spoke out — so passionately and so thoughtfully — about this issue. Our thinking was informed by The Harvard Crimson editorials, by Undergraduate Council proposals, by consultation with the Honor Council, but it was informed just as much by the individual emails sent by so many of you. We have tried, in this new policy, to address the needs of all of our students, while also responding to the enormity of the situation we find ourselves in.” “We of course remain committed to academic continuity, but we cannot proceed as if nothing has changed. Everything has changed.” — Claudine Gay ‘Unsteady,’ ‘lucky,’ and ‘overwhelmed’ Some running into minor hitches, but others finding surprising benefits Students reflect on the shift to online classes and unplanned move home Officials detail University’s battle plan to combat coronavirus while education continues Q&A on Harvard’s move to online learning Early responses indicate shift to online classes going well overall The Daily Gazette Sign up for daily emails to get the latest Harvard news.
