Influence of Patagonian glaciers on Antarctic dust deposition during the last glacial period

first_imgIce cores provide a record of changes in dust flux to Antarctica, which is thought to reflect changes in atmospheric circulation and environmental conditions in dust source areas(1-9). Isotopic tracers suggest that South America is the dominant source of the dust(10-12), but it is unclear what led to the variable deposition of dust at concentrations 20-50 times higher than present in glacial-aged ice(8,9). Here we characterize the age and composition of Patagonian glacial outwash sediments, to assess the relationship between the Antarctic dust record from Dome C (refs 9, 13) and Patagonian glacial fluctuations(14-16) for the past 80,000 years. We show that dust peaks in Antarctica coincide with periods in Patagonia when rivers of glacial meltwater deposited sediment directly onto easily mobilized outwash plains. No dust peaks were noted when the glaciers instead terminated directly into pro-glacial lakes. We thus propose that the variable sediment supply resulting from Patagonian glacial fluctuations may have acted as an on/off switch for Antarctic dust deposition. At the last glacial termination, Patagonian glaciers quickly retreated into lakes, which may help explain why the deglacial decline in Antarctic dust concentrations preceded the main phase of warming, sea-level rise and reduction in Southern Hemisphere sea-ice extent(13).last_img read more

Virginia-Class Fast Attack Submarine USS Hawaii Visits Busan

first_img View post tag: Navy July 23, 2012 View post tag: visits View post tag: News by topic The Virginia-class fast attack submarine USS Hawaii (SSN 776) arrived in Busan July 20 as part of a deployment to the Western Pacific.“As we represent our submarine team, our Navy, and our country, we are committed to our to our presence in the Western Pacific and look forward to many more visits with our friends and allies in the region,” said Cmdr. Steve Mack, Hawaii’s commanding officer.Hawaii’s visit to Busan presents a chance to strengthen ties and train with a key U.S. ally as well as provide the crew with some much needed liberty.“For our Sailors, after 14 months of very hard work qualifying and diligently training on various watchstations throughout the sub, WESTPAC deployments and their liberty ports are the reward that makes all of their efforts worthwhile,” said Electronics Technician Master Chief John Perryman, Hawaii’s chief of the boat.For many of the crew members, this is their first time visiting Busan.“I’m really excited to get a chance to see South Korea and go shopping at the International Market,” said Torpedoman Fireman Adrian Mansaw. “I have lots of friends back home in Kansas City who won’t believe that I’m calling them from so far away!”Hawaii measures more than 370 feet long and weighs more than 8000 tons when submerged. The submarine is capable of supporting a multitude of missions, including anti-submarine warfare, anti-surface ship warfare, strike, naval special warfare involving special operations forces, intelligence, surveillance and reconnaissance, irregular warfare and mine warfare.[mappress]Naval Today Staff, July 23, 2012; Image: US Navy View post tag: attack Share this article Training & Education View post tag: Busan View post tag: Virginiacenter_img View post tag: fast View post tag: Hawaii Virginia-Class Fast Attack Submarine USS Hawaii Visits Busan View post tag: USS Back to overview,Home naval-today Virginia-Class Fast Attack Submarine USS Hawaii Visits Busan View post tag: submarine View post tag: class View post tag: Navallast_img read more

Q&A:

first_imgQOne of our employees is responsible for placing all our stationery orders. The supplier we use regularly runs competitions and, this month, our employee has been selected as its winner; the prize is a digital camera. This has caused bad feeling among other staff and a few have proposed that it is raffled off for a local charity. We don’t have a problem with this, but the winner is refusing to hand it over; he claims the camera is legally his. So does it belong to us (as it was our order) or our employee (because he was the contact name when it was placed)?AUnfortunately, many suppliers do this. Rather than being a “prize”, the item on offer is really just an incentive for customers to place orders; the same rule applies to free gifts. However, the bottom line is that this type of item belongs to you, not your employee, no matter what he says. This is because, when the order was placed, he was acting on your behalf during the course of his employment, in other words, it wasn’t his personal order. So it is perfectly acceptable for you to demand that he hand the prize over. If you wish to raffle it off as suggested, that is entirely your choice. Alternatively, it could be retained as a business asset. Energy efficiency certificates We have had a couple of enquiries recently from members saying that someone has contacted them informing them that they have to have an ’Energy Efficiency Certificate’. If they didn’t they could be fined £5,000. This is totally untrue; the only time you would need this certificate would be if you were selling or leasing/renting a property.Further information and details are available at: http://tinyurl.com/64pws73.last_img read more

When a bird brain tops Harvard students on a test

first_img A study of YouTube star Snowball the cockatoo suggests humans may not be the only ones who can groove to a beat After using tools, the birds behave more optimistically, study suggests Clever crows Related Study shows parrots can pass classic test of intelligencecenter_img What happens when an African grey parrot goes head-to-head with 21 Harvard students in a test measuring a type of visual memory? Put simply: The parrot moves to the head of the class.Harvard researchers compared how 21 human adults and 21 6- to 8-year-old children stacked up against an African grey parrot named Griffin in a complex version of the classic shell game.It worked like this: Tiny colored pom-poms were covered with cups and then shuffled, so participants had to track which object was under which cup. The experimenter then showed them a pom-pom that matched one of the same color hidden under one of the cups and asked them to point at the cup. (Griffin, of course, used his beak to point.) The participants were tested on tracking two, three, and four different-colored pom-poms. The position of the cups were swapped zero to four times for each of those combinations. Griffin and the students did 120 trials; the children did 36.The game tests the brain’s ability to retain memory of items that are no longer in view, and then updating when faced with new information, like a change in location. This cognitive system is known as visual working memory and is the one of the foundations for intelligent behavior.So how did the parrot fare? Griffin outperformed the 6- to 8-year-olds across all levels on average, and he performed either as well as or slightly better than the 21 Harvard undergraduates on 12 of the 14 of trial types.That’s not bad at all for a so-called bird brain.,“Think about it: Grey parrot outperforms Harvard undergrads. That’s pretty freaking awesome,” said Hrag Pailian, the postdoctoral fellow at the Graduate School of Arts and Sciences who led the experiment. “We had students concentrating in engineering, pre-meds, this, that, seniors, and he just kicked their butts.”Full disclosure: Griffin has been the star of past cognitive studies, like showing he’s smarter than the typical 4-year-old and as intelligent as a 6- to 8-year-old child. But making Harvard students do a double take on their own intelligence is quite the step up.To be fair, the Harvard students did manage to keep (some) of their Crimson pride intact. On the final two tests, which involved the most items and the most movement, the adults had the clear edge. Griffin’s average dipped toward the children’s performance — though never below it. The researchers were unable to determine the precise reason for this drop, but they believe it has something to do with the way human intelligence works (arguably making the Harvard students’ victory a matter of performance enhancement of the genetic variety).The experiment was part of a study published in Scientific Reports in May. Pailian was the lead author and he collaborated with comparative psychologist Irene Pepperberg, Henry A. Morss Jr. and Elisabeth W. Morss Professor of Psychology Susan Carey, and Justin Halberda at John Hopkins University.The researchers were investigating the limits of the brain’s ability to process and update mental representations. In other words, they were looking at the “working” portion of the visual working memory system. The ability is referred to as manipulation. And ultimately, they were hoping to gain insights into the development and origin of the visual working memory system and the nature of human intelligence.“Any operation that you perform in your mind, it takes place in visual working memory,” Pailian said. “You store information from the outside world; you play around with it; and then you shuttle it up for higher cognition. It helps fuel STEM aptitude, mental wellness, and all these different types of important cognitive attributes …. We think that one of the main components of human intelligence, the key characteristic is that we’re able to think about all these things in our minds and do these mental manipulations, but if we find that other animals, other species can perform those manipulation operations [and also see how ancient this ability is], maybe that can help us inform what delineates human intelligence from other animal intelligence, as well.”,At a broad level, the paper’s findings hint at the possible evolutionary origins of the ability to manipulate visual memory. Griffin’s success suggests it is not limited to humans and might be shared across species derived from a common ancestor. In this case, the ancestor would be the dinosaurs, since humans and parrots are separated by more than 300 million years of evolution.“We’re suggesting that it’s possible — we can’t prove this — that dinosaurs, our common ancestor, may have had some basic capacity,” said Pepperberg, a research associate in Harvard’s Psychology Department. “Then this [advanced manipulation] ability could have evolved in parallel [in primates and birds]. The other possibility is that our common ancestor lacked this ability, and it somehow arose independently in these two lines. But we’re arguing that because manipulation is built on storage capacity, and so many different species have similar storage capacities, that some simple form of manipulation likely existed in a common ancestor.”In the paper, the researchers note that future work is needed to confirm manipulation ability across a wider variety of species and identify its origins.“It’s not that we proved everything provable,” Pepperberg added. “It’s that we’ve demonstrated a behavior that leads to a lot of different questions.”Griffin was a prime candidate for this experiment because the researchers needed an animal whose brain was functionally similar to humans but evolutionarily distant for comparison. It was also likely that parrots possessed the manipulation ability because of environmental pressures in the wild, like tracking their hungry fledglings or threats like predators. Plus, Griffin is always ready to show off his brain power and earn a few cashews as a reward.“He’s the kind of student who asks you, ‘What do I have to do to get the A?’” and then goes and does it, Pepperberg said.

NBC sitcom creator speaks at Notre Dame, makes connections to philosophy coursework

first_imgWriter, producer and actor Mike Schur spoke in Washington Hall on Monday as part of a lecture discussing the role television plays in a society’s morality.Schur created or worked on a wide variety of popular shows, including “The Office,” “Parks and Recreation” and “The Good Place.” He was invited by Paul Blaschko, who teaches the philosophy course “God and The Good Life” at Notre Dame.Blaschko said Schur’s shows are often “deeply philosophical.”“‘The Good Place’ is an obvious example of this,” he said. “It’s a show about a moral philosophy professor guiding others through a journey of moral growth in the afterlife. But the other shows [‘The Office’ and ‘Parks and Recreation’] can be very philosophical, too. Indeed, the best television — especially comedy — almost always is.”Blaschko said he believes the lecture will help his students to relate what they have been learning in class to real and contemporary concerns.“‘God and the Good Life’ takes on big philosophical questions each day,” he said. “We’re just finishing our unit on morality and the good life, and Mike’s talks will help students apply these issues, and the moral theories we’ve been talking about, to practical questions. How should you watch television? Can we do philosophy while making good entertainment? Is there a way of approaching big philosophical questions through a career in entertainment?”Laura Callahan, assistant professor of philosophy at Notre Dame, said “The Good Place” helped to bring “philosophical theories to life for an extraordinarily wide audience.”“This is also one of the central ambitions of ‘God and the Good Life’ — making philosophical theories and questions feel relevant to students’ lives, making philosophy have an impact,” she said. “We’re beyond thrilled that this extraordinarily talented person is coming to share that energy and perspective with our students.”Sullivan said in addition to being “totally hilarious,” Schur’s shows have several parallels to the curriculum of the “God and the Good Life” course.“We invited him to speak to the philosophy students because his shows raise many of the same questions we wrestle with in our ‘God and the Good Life’ course — how do we become better people? What do we owe each other? What does it mean to have faith … in God, in your friends, in your fellow citizens?”Sullivan said she hopes her students walk away with three major ideas.“First, it’s a key part of virtue ethics that we should feel joy at pursuing the good life,” she said. “I want them to give some thought to how and why morality can also be quite funny. Second, I want them to see a writer and producer who is arguably at the top of his craft and who simply could not do this incredible work without curiosity about philosophy. Third, we hope to keep the conversation going for the rest of the year in class about what exactly we need to do to make sure we don’t end up as medium people … [and] we end up as good people.”Tags: god and the good life, Parks and Recreation, The good place, The Officelast_img read more

BAVO promotes women’s empowerment with crafting activity

first_imgThe Belles Against Violence Office (BAVO) hosted an empowerment board activity on Wednesday evening to help students focus on setting and achieving personal goals. The organizers hoped this activity would help students recognize their potential and worth, a message that is part of BAVO’s core mission. “I think this activity really aligns with BAVO’s mission for women’s empowerment,” junior Elizabeth Day, who helped organize the event, said. ”It is a visual way to represent your goals and recognize the things that you aspire to be and the things that inspire you.” This year BAVO has tried to find new ways to connect with students and share their mission. “This year we’re really trying to get creative with our events and find new ways to empower women,” Day said. “We want to host events that people will be excited about and start conversations about important topics.” The concept of an empowerment board plays off the idea of a vision board, but students thought a vision board could have a negative effect on participants. Instead, BAVO opted for a more positive message for this event. “We thought a vision board would be cool, but once we started looking into it, we noticed that a lot of people online were saying how stressful it was when they looked at their vision boards and felt like they hadn’t accomplished any of their goals,” senior and BAVO member Lauren Zinanni said. “We thought about empowerment boards instead because BAVO strives to empower women, especially on this campus.” Students in attendance found designing empowerment boards to be a good way to get involved and apply this activity to their own lives. “I have a lot of projects coming up, so I think this is a nice way to take a break and still be creative,” junior Corey Shaw said. ”I think that having one is a nice reminder to never give up.” For Shaw, having boards like these serve as a daily reminder to remain positive and to stay focused on her goals.“All of this work is going towards a goal,” she said. “I have a lot of these types of things in my room already, so this is just another reminder that I’m here for a reason and I need to keep going to make the goal that I’m trying to get to.” Members of BAVO hope events like this will help spread the organization’s mission to students and encourage everyone to get involved. “I think its important that BAVO does these events not only so students on campus can become more aware of BAVO’s presence, but also so students can be creative and work on a project to take something home,” Zinanni said. “It’s important to show that BAVO is a resource for students and we’re glad that we’ve been such a big presence on campus this year.”The concept of empowerment is significant for many students and the ability to design a board had a positive effect on students. “A lot of people told me I wouldn’t make it this far,” Shaw said. “So, the fact that I did and that I have boards like this reminds me of this and why I’m here. It helps me remember that I proved them wrong.” Tags: BAVO, Belles Against Violence Officelast_img read more

WOCCU reflects on 25 years

first_imgby: Michael MuckianIn 1990, credit unions were in a different place than they are today. During the ensuing 25 years, their influence has increased, but their challenges also have escalated. The same holds true for their trade associations, especially when viewed from a global perspective.World Council of Credit Unions has evolved into more of an advocacy role over the past 25 years. Unlike its domestic counterparts, the Madison, Wis.-based trade group advocates on behalf of the global credit union movement, helping strengthen the credit union idea in the minds of policymakers worldwide and promote the influence of proper governance for both established and emerging movements, according to World Council President/CEO Brian Branch. continue reading » 1SHARESShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblrlast_img read more
