A review of sea ice proxy information from polar ice cores

first_imgSea ice plays an important role in Earth’s climate system. The lack of direct indications of past sea ice coverage, however, means that there is limited knowledge of the sensitivity and rate at which sea ice dynamics are involved in amplifying climate changes. As such, there is a need to develop new proxy records for reconstructing past sea ice conditions. Here we review the advances that have been made in using chemical tracers preserved in ice cores to determine past changes in sea ice cover around Antarctica. Ice core records of sea salt concentration show promise for revealing patterns of sea ice extent particularly over glacial–interglacial time scales. In the coldest climates, however, the sea salt signal appears to lose sensitivity and further work is required to determine how this proxy can be developed into a quantitative sea ice indicator. Methane sulphonic acid (MSA) in near-coastal ice cores has been used to reconstruct quantified changes and interannual variability in sea ice extent over shorter time scales spanning the last ∼160 years, and has potential to be extended to produce records of Antarctic sea ice changes throughout the Holocene. However the MSA ice core proxy also requires careful site assessment and interpretation alongside other palaeoclimate indicators to ensure reconstructions are not biased by non-sea ice factors, and we summarise some recommended strategies for the further development of sea ice histories from ice core MSA. For both proxies the limited information about the production and transfer of chemical markers from the sea ice zone to the Antarctic ice sheets remains an issue that requires further multidisciplinary study. Despite some exploratory and statistical work, the application of either proxy as an indicator of sea ice change in the Arctic also remains largely unknown. As information about these new ice core proxies builds, so too does the potential to develop a more comprehensive understanding of past changes in sea ice and its role in both long and short-term climate changes.last_img read more

National Plans of Action (NPOAs) for reducing seabird bycatch: Developing best practice for assessing and managing fisheries impacts

first_imgFisheries bycatch is one of the biggest threats to seabird populations. Managers need to identify where and when bycatch occurs and ensure effective action. In 1999, the Food and Agriculture Organization of the United Nations released the International Plan of Action for Reducing Incidental Catch of Seabirds in Longline Fisheries (IPOA-s) encouraging states to voluntarily assess potential seabird bycatch problems and implement a National Plan of Action (NPOA) if needed. However, the IPOA-s is ambiguous about the steps and objectives, diminishing its value as a conservation tool.last_img

Man behind the van

first_imgI work in Mehdi’s kebab van which is on the High Street between Oriel College and Turl Street. I’ve worked in the same van on the same spot since I came to England in 1994. Before I took over the business my father did the same for 12 years.We’re very famous in Oxford and my van has even been voted the best. When the students are in Oxford I work seven days – well, seven nights – a week. You can’t take a single day off because customers start asking about you!I finish at around three o’clock every morning and get three or four hours of sleep. When I wake up I usually visit my brother-in-law at his café on Broad Street, go shopping and watch some TV. Then I try to get about four more hours of sleep before starting work again each evening at five o’clock.My van has to be on the High Street ready to serve by half past six. It might seem like a lot but I don’t think the work is too hard and I’m used to it. But it does mean I don’t get much chance to spend time with my family during term time. That’s why I take long holidays, for two or three weeks, whenever the students go back home.In the summer I go away for four or five weeks, usually to Morocco where I was born. This year I went to Marrakech where my sister lives. I’m 35 now, but I moved to England from Tangier at the age of 24 to be with my wife – I met her in Morocco but she herself was already living in England. When I go back to Morocco now I don’t know how I cope with the heat, I’m so used to living in England.In Marrakech it’s 45°C in August at least, and I can’t breathe! I’m a Muslim so obviously I can’t drink but dealing with drunk students every night doesn’t bother me in the slightest. If other people want to drink that’s fine with me. Everyone has their own ideas and their own feelings and beliefs. At the moment working nights actually suits my religious beliefs as I’m currently fasting for Ramadan and can’t even accept an offer of coffee during the day! Since I work at night sometimes I do get trouble from drunken customers. Last night for instance one man was determined to argue about his order. I just stayed calm and gave him his money back. But it’s not a massive problem because I’m used to dealing with drunk customers.I know the mentality and I know how to deal with it. If they want to argue with you, you don’t argue back. If they start swearing at you, you don’t start swearing back. You just have to get on with your job and make them happy. I actually think my work has made me quite diplomatic. One of the best parts about my job is that you meet people from all over the world.Every night you meet different people from different countries and different cultures. In the summer especially there are tourists in Oxford from Europe, America – in fact, everywhere. But at the same time you get to know a lot of regular customers very well; some people have been coming to my van for 15 to 20 years.What’s my opinion of Oxford students? Well, they’re normal. And generally very nice. Sometimes in the morning when I’m not working I come across regular customers on the street and they’re very happy to see me. Like lots of other businesses in Oxford, my business depends on students. I need them to survive. Without students, Oxford is nothing.ARCHIVE: 3rd week MT 2005last_img read more

Pret enjoys big boost to turnover

first_imgPret A Manger has reported a 17% increase in both turnover and ebitda, as the chain continues to expand in the UK.The top 10 BB75 retailer posted sales revenue of £443m, and ebitda of £61.1m for 2012 financial year. It also opened 36 new shops – 19 of which were in the UK – over the 52-week period, taking its total estate to 320 (+10%).A target of 50 new shops has been set for 2013, including four additional shops in Paris. Of the 1,000 jobs due to be created, 500 of these should be in the UK, said the firm.Following previous criticism about the number of British workers it employs, the firm highlighted the launch of its fledgling National School Leaver Programme, which encourages British school leavers to work for the company.Nine school leavers have also joined the team, with the scheme to be expanded in September this year, it said.Clive Schlee, chief executive of Pret A Manger, said: “2012 was a strong year for Pret. We continued to invest in our core values, improving our menu, launching innovative employment schemes and building and refurbishing shops in all our markets.”Last year also saw Pret open its first shop in Paris, and in its fourth city in the US – Boston.last_img read more

Scottish ingredients firm enjoys rise in turnover

first_imgIndependent bakery ingredients manufacturer Macphie has reported a 3.5% growth in turnover to £44.4m. The results, to March 2014, have been attributed to “stronger trading across foodservice and food manufacturing channels” as an effect of increasing consumer confidence. However, the continuation of unsettled raw material prices, particularly in the dairy sector, has impacted on gross margin, which decreased by 5% on the previous year, the company said.The company has brought all outstanding R&D tax claims up to date over the past 12 months, resulting in an overall positive profit position of £2m.Alastair Macphie, chairman, said: “The current economic climate will continue to be a challenge, both in the UK and internationally. However, we are pleased to see some positive early signs of recovery. Looking forward we will continue our significant operational capital investment programme and award-winning employee development initiatives, to ensure we remain the vital ingredient for our international customer base.”In January Macphie moved from his position as chief executive to chairman to focus on longer-term objectives. Andrew Underwood replaced him as chief executive.last_img read more

Infamous Stringdusters Cover The Dead, Phish, Daft Punk, MMJ, Marvin Gaye, & More [Videos]

Mimna [Video: Aimee Riegel]“Hitchhiker” > “Shakedown Street” In a genre deeply rooted in tradition, songwriting, and standards, bands stand out in the world of bluegrass in two ways: top-notch vocals and impeccable musicianship. With the Infamous Stringdusters, you get both. Not only are all five members virtuosic at their instrument of choice, four out of five confidently step into the role of lead vocalist and can croon and harmonize with the best of them. Kicking off a two-night run at Denver’s Ogden Theater Friday night, the five-piece powerhouse delighted a lively crowd of costume-clad fans during two-sets filled with jam-band teases, choice covers, and plenty of good old-fashioned bluegrass.Infamous Stringdusters Cover Allman Bros., Marvin Gaye, Daft Punk, MMJ, & More On Upcoming EPThe Dusters are a tight-knit group, and their improvisations are bolstered by their movement onstage. With the exception of Andy Hall’s dobro, all other members—Andy Falco on guitar, Chris Pandolfi on banjo, Jeremy Garrett on fiddle, and Travis Book on upright bass—play wirelessly and parade around the entirety of the stage. One song the band will be in a tight cluster stage left, the next Pandolfi and Falco will be partnered up shredding while the rest form a triangle on the opposite side of the stage. Look away and you may come back to find the whole band intertwining in a chaotic atomic frenzy.The band released a new album at the show Friday night, a five-song compilation of covers called Undercover II, which was recorded in Boulder at the Etown radio show earlier in the year. To celebrate, they ended the first set by playing the album in its entirety. First it was The Cure’s “Just Like Heaven,” followed by “Golden” by My Morning Jacket. A note-for-note rendition of the Allman Brother’s instrumental classic “Jessica” followed, before Book—arguably the best voice of the bunch—took over vocals for Marvin Gaye’s “What’s Goin On.” The album was rounded out with a Halloween-inspired take of Daft Punk’s “Get Lucky” that saw each member put on a space helmet akin to the ones famously worn by the French duo.Watch Members of Railroad Earth, Infamous Stringdusters, & More Perform As DrewciferThe second set played right into the hands of the jammy home-state crowd, opening with the hit “Colorado” that fell into a tease of Phish’s “Bathtub Gin,” the first of a handful of short teases that would perk the crowd’s interest. A dobro tease of the Grateful Dead’s “West LA Fadeaway” dropped into “Get It While You Can,” the Dead’s “Shakedown Street” let Falco erupt on guitar, and the climatic build of “Also Sprach Zarathustra” (more famously known as Phish’s “2001”) led into a bluegrass hoedown. The Dusters left plenty of room for their original material, “A Hard Life Makes a Good Song” was a standout, but Friday night was more about letting loose and having a little sing-a-long fun.The band will be back at the Ogden Theater tonight to close out their Denver run.[Cover Photo: Scott Seifert]Setlist: The Infamous Stringdusters | Ogden Theater | Denver, CO | 10/27/2017Set One: Canyon, Hard Life > Sirens, Back Home > Black Elk, Just Like Heaven, Golden > Jessica, What’s Going On > Get LuckySet Two: Colorado > Red Fox, Vertigo, For What It’s Worth > Let Me Know, Ring, All That I Can Take > Get It, Hitchhiker > Shakedown Street, Space > Tragic, Gravity > HC Funk > 2001 > BlockygrassJust Like Heaven[Video: Kyle Isaac]“Colorado” > “Red Fox”[Video: Kyle Isaac]“For What It’s Worth”last_img read more

NFL chief talks player safety at HSPH

first_imgIn 1905, 18 college football players died of injuries — mainly skull fractures — sustained playing the game. Another 150 were injured.The high level of casualties came at a time when far fewer colleges played a more dangerous brand of football, and led to a public outcry — Columbia University banned the game — and to the intervention of a prominent Harvard alum: President Theodore Roosevelt.Roosevelt called representatives from Harvard, Yale, and Princeton to the White House and urged them to discuss rule changes that would make the game safer. They approved the forward pass and the 10-yard distance to a first down, and established the precursor to the National Collegiate Athletic Association (NCAA) to oversee the sport.On Thursday, National Football League (NFL) Commissioner Roger Goodell recalled those turn-of-the-century changes — and Harvard’s role in them — to highlight current reforms meant to enhance player safety. Those changes, he said, are part of an evolution that will continue“Football has always evolved and it always will,” Goodell said. “My commitment has been and continues to be to change the culture of football to ensure player safety.”Goodell, who spoke at the Harvard School of Public Health (HSPH), leads the league at a time when player safety is in the spotlight. Several lawsuits have been filed by former players arguing that the league did too little to protect them against the negative effects of repeated concussions, which can be debilitating even years removed from the field.The league, Goodell said, can employ a variety of tactics to improve safety, from new equipment to rules changes to guidelines for sideline medical personnel. In recent years, rules have been enacted to protect quarterbacks and defenseless receivers, to eliminate helmet-to-helmet contact, and to minimize injuries on kickoffs, the game’s most dangerous play. Horse-collar tackles, facemasking, and head slaps have also been targeted, while awareness has been raised to protect against heat- and hydration-related illness. <a href=”https://www.youtube.com/watch?v=jYApiOB39pw” rel=”nofollow” target=”_blank”> <img src=”https://img.youtube.com/vi/jYApiOB39pw/0.jpg” alt=”0″ title=”How To Choose The Correct Channel Type For Your Video Content ” /> </a> The push to make the game safer, Goodell said, extends to all levels, including high school, where the NFL has pushed for state legislation mandating players be removed from games in the event of a concussion and not return until medically cleared.HSPH Dean Julio Frenk introduced Goodell, who spoke in the Kresge Building cafeteria before about 200 as part of the Dean’s Distinguished Lecture series. Frenk said that sports are an important part of ensuring a healthy lifestyle and fighting the nation’s obesity epidemic, but that safety is paramount. When it comes to sports injuries, he said — particularly concussions — a lot of work remains.In his talk, delivered two days before the Harvard-Yale game, Goodell highlighted Harvard’s central role in the game’s origins. The football first played at Harvard in 1873 was a very different game, however, with little protection for players and dangerous tactics like the flying wedge — outlawed in the 1890s. He cited Harvard successes past and present — eight national championships and 20 players inducted into the college football Hall of Fame; graduates Ryan Fitzpatrick and Matt Birk playing, respectively, for the Buffalo Bills and the Baltimore Ravens.“Football is embedded in your traditions, and your contributions define how we play the game,” Goodell said.Goodell highlighted the importance of sports in fighting the obesity epidemic and cited the NFL’s continuing popularity in his optimism about the league’s future. Enthusiasm for the game extends well below the professional level, he said, with 75,000 college players, 1.1 million high school players, and 6 million kids playing below the high school level.Making the game safer will require more than rules and equipment changes, Goodell said. It will require a change in a culture that has always prized toughness and the ability to play through pain and injury. Though there has been a greater effort in recent seasons to identify players who suffer concussions and remove them from the game, that battle has to be waged by more than just the sideline medical personnel. Players themselves — often reluctant to come out of the game — have to be more forthcoming about their injuries, Goodell said.last_img read more

Missouri lawmaker asked to resign amid stem cell fraud case

first_imgSPRINGFIELD, Mo. (AP) — A Missouri state lawmaker indicted on federal fraud charges for falsely claiming a treatment she sold contained stem cells that could help with COVID-19 has been asked to resign. The Missouri House speaker on Wednesday said fellow Republican Rep. Tricia Derges should step down after a federal grand jury indicted the Nixa legislator. The 20-count indictment also accuses the 63-year-old of illegally providing prescription drugs to clients and making false statements to federal agents investigating the case. Her defense attorney says Derges “hasn’t been convicted of a thing and she is presumed innocent.”last_img

Gifford receives $40,000 Avon Foundation grant

first_imgGifford Healthcare,RANDOLPH – Gifford Medical Center has been awarded an Avon Foundation Breast Care Fund grant for the eighth consecutive year. The only hospital in the state to receive the national award, Gifford has been granted $40,000 for 2009 to increase awareness of the life-saving benefits of early detection of breast cancer.The Avon Foundation Breast Care Fund supports community-based, non-profit breast health programs across the country. Gifford was selected as one of 144 grant recipients nationwide. Organizations are chosen based on their ability to effectively reach women, particularly minority, low-income and older women, who are often medically underserved.In 2008, Gifford, through the Avon Foundation’s generosity, reached 4,285 women during educational visits, a total estimated audience of more than 200,000 with the help of the media, and scheduled 571 women for mammograms – all numbers that significantly exceeded prior years.Gifford’s outreach is done primarily by Breast Care Coordinator Jane Harrness, a mammography technologist, who speaks around the state about the importance of annual mammograms in detecting breast cancer early.The grant – designated for outreach and education – makes her work possible.”Gifford is proud and thankful to receive this grant. It is an immeasurable gift,” Harrness said. “We can help women access the health care system and learn the importance of taking care of themselves. Women are so thankful for the information on breast health that I am able to give them.”Gifford and Harrness have historically used the funding to outreach to women where they live, work and socialize. That has meant numerous visits to senior centers and senior living facilities, public events and conferences, and Vermont’s women’s prisons and halfway houses.Instrumental in Harrness’ efforts in 2008 was attendance at many of the state’s county fairs and the Vermont Farm Show in Barre – events that typically draw rural Vermonters.This year, attendance at rural happenings, like the state’s fairs and this month’s farm show, will continue to be part of the hospital’s ongoing efforts to educate medically underserved women in Randolph, central Vermont and statewide – including a population of French-Canadian women living in the rural Northeast Kingdom – on the importance of mammograms and clinical breast exams.The grant award also serves as a resource and motivation to reach media outlets with advertisements, public service announcements and news stories regarding breast health.Among Gifford’s messages of late are promoting the state’s new affordable mammogram law, which went into effect on Oct. 1 and limited the out-of-pocket cost for a woman age 40 and over with Vermont insurance to just $25 or less.The Randolph hospital is also a supporter of the Love/Army for Women, a national effort to have women sign up for breast cancer research initiatives. Any woman, except those in active cancer treatment, is encouraged to join at www.armyofwomen.org(link is external). The program includes e-mail alerts on upcoming scientific studies. Women who fit the parameters of a study are invited to participate.Breast cancer is the most frequently diagnosed cancer in U.S. women, and the single leading cause of death overall in women between the ages of 40 and 55.In Vermont last year, an estimated 470 new cases of female breast cancer cases were diagnosed and 90 women died from the disease, according to the American Cancer Society.Nationwide, there is a new diagnosis of breast cancer every three minutes and a death every 14 minutes.While advances – including the new Love/Army of Women research strategy – have been made in prevention, diagnosis, treatment and working toward a cure for breast cancer, early detection still affords the best opportunity for successful treatment. According to the Avon Foundation, programs such as Gifford’s help ensure that all women, including the poor and medically underserved, have access to early detection information and options.Since 1993, the Avon Foundation has awarded more than 1,100 grants to community-based breast health programs across the United States. These programs are dedicated to educating underserved women about breast cancer and linking them to early detection screening services.The Avon Foundation and Breast Cancer CrusadeThe Avon Foundation, an accredited 501(c)(3) public charity, was founded in 1955 to improve the lives of women and their families. Now past the half century milestone, the Foundation brings this mission to life through the Speak Out Against Domestic Violence program and the Avon Breast Cancer Crusade, which raises funds and awareness to advance access to care and finding a cure for breast cancer, with a focus on the medically underserved. Since 1992 the Avon Breast Cancer Crusade has raised and awarded more than $525 million worldwide for medical research, access to care, support services, screening and diagnostics, and education and awareness. The largest fundraising program in the United States is the Avon Walk for Breast Cancer series.The Avon Foundation Breast Care FundThe Avon Foundation Breast Care Fund is administered by Cicatelli Associates Inc. to support community-based, non-profit breast health programs across the country. The Fund’s National Advisory Board selected the breast health program at Gifford Medical Center as one of 144 grant recipients nationwide in 2009. These organizations were chosen based on their ability to effectively reach women, particularly minority, low-income and older women, who are often medically underserved.Gifford Medical CenterGifford Medical Center in Randolph, Vt., is a community hospital with family health centers in Bethel, Chelsea, Rochester and Sharon and specialty services throughout the region. Gifford is a full-service hospital with a 24-hour emergency department, a 25-bed inpatient unit and a Transitional Care Unit. Gifford has a day care as well an adult day care and a 30-bed nursing home, the Menig Extended Care Facility, which opened in 1998 on the main campus. The Birthing Center, established in 1977, was the first in Vermont to offer an alternative to the traditional hospital-based deliveries and continues to be a leader in midwifery and family-centered care.The hospital’s mission is to improve individuals’ and community health by providing and assuring access to affordable and high-quality health care in Gifford’s service area.For more InformationFor more information on breast care at Gifford, call Breast Care Coordinator Jane Harrness at (802) 728-2317.
