Energetic electron precipitation associated with pulsating aurora: EISCAT and Van Allen Probe observations

first_imgPulsating auroras show quasi-periodic intensity modulations caused by the precipitation of energetic electrons of the order of tens of keV. It is expected theoretically that not only these electrons but also sub-relativistic/relativistic electrons precipitate simultaneously into the ionosphere owing to whistler-mode wave–particle interactions. The height-resolved electron density profile was observed with the European Incoherent Scatter (EISCAT) Tromsø VHF radar on 17 November 2012. Electron density enhancements were clearly identified at altitudes >68 km in association with the pulsating aurora, suggesting precipitation of electrons with a broadband energy range from ~10 keV up to at least 200 keV. The riometer and network of subionospheric radio wave observations also showed the energetic electron precipitations during this period. During this period, the footprint of the Van Allen Probe-A satellite was very close to Tromsø and the satellite observed rising tone emissions of the lower-band chorus (LBC) waves near the equatorial plane. Considering the observed LBC waves and electrons, we conducted a computer simulation of the wave–particle interactions. This showed simultaneous precipitation of electrons at both tens of keV and a few hundred keV, which is consistent with the energy spectrum estimated by the inversion method using the EISCAT observations. This result revealed that electrons with a wide energy range simultaneously precipitate into the ionosphere in association with the pulsating aurora, providing the evidence that pulsating auroras are caused by whistler chorus waves. We suggest that scattering by propagating whistler simultaneously causes both the precipitations of sub-relativistic electrons and the pulsating aurora.last_img read more

Research may provide the tools to create better schools

first_imgJust as clinical trials are critical to enhancing human health and medicine, field experiments are critical to understanding human learning and education, according to a new paper published in the online journal Science.A team of economists and psychologists at Harvard and Massachusetts Institute of Technology (MIT), working together with organizations focused on enhancing education and reducing poverty in India, have demonstrated both the feasibility and the necessity of such experiments, the study noted.“Research in cognitive science has taught us a great deal about what children know and how they learn,” said Harvard Professor Elizabeth Spelke, the Marshall L. Berkman Professor of Psychology and one of the paper’s authors. “Much of that work applies to all children, worldwide, and it gives us methods for assessing children’s knowledge that are robust enough to work when implemented by adults with only high school education, working with children in hot and noisy slums. This research doesn’t tell us how to create better schools, but it gives us the tools to do field experiments that can.”While primary education now is compulsory in India, it was not widespread a generation ago. Poor Indian children are likely to live in families and communities with high rates of illiteracy and innumeracy. Countrywide studies show that many fail to learn the basic concepts and skills taught in primary schools, in large part because the curricula taught in the schools assumes a level of preparation that is not there.Drawing on decades of cognitive science research probing the nature and early development of mathematical reasoning, the Harvard and MIT team created a program for enhancing poor children’s readiness to learn mathematics, and evaluated it over a period of 18 months. More than 200 single-class preschools serving 1,500 children in Delhi were randomized to three conditions. One group received a math curriculum consisting of games training two aspects of intuitive mathematics: sensitivity to numbers, and geometry. Children from wealthy countries master these intuitive mathematics over their preschool years, and research in cognitive science suggests this is critical for later learning of symbolic mathematics.A second group received a curriculum of games with the same structure that trained sensitivity to aspects of human communication: sensitivity to emotional expressions and signs of attention. This skillset also develops in preschool and is widely thought to be critical to learning from others, but was not expected to affect math directly. Over a four-month period, the games were played for three weekly one-hour sessions in these two groups, while a third group of children received the regular preschool curriculum.To measure the effects of the games, all the children were assessed on a variety of abilities, including intuitive abilities close to the content of the games in the two curricula, such as determining which of two sets of objects was more numerous or which of two faces was happier, and symbolic abilities at the center of the primary school curriculum, such as identifying Arabic numerals or naming shapes.In the summer months immediately following preschool, the children showed effects of the math games intervention that closely paralleled effects found in Western children from developed countries: higher sensitivity to numbers and geometry on the intuitive measures that were close to the games, and also better mastery of the language and symbols of intuitive, preschool mathematics. In these respects, the study strongly confirmed the central findings from basic research in the cognitive science of mathematics, showing that those findings generalize across children living and learning in very different circumstances. Moreover, they show that field interventions can be effective, not only when implemented in carefully controlled model classrooms but also when implemented and evaluated by adults with minimal training and little connection to the research team.Shortly after the end of the first year of primary school, the children who had received the math games curriculum still reliably outperformed the other children at tests of intuitive numerical and spatial abilities. Although these children had no access to the math games after the end of the intervention, the benefits from the games persisted.In striking contrast, the intervention showed no effect on children’s mastery of symbolic school mathematics: By the end of first grade, children in the math games condition were no better than those in the other two conditions at deciphering Arabic numerals, performing simple verbal additions, or learning the vocabulary of school geometry. Just as well-supported findings in molecular biology do not guarantee the success of new medical treatments, key findings in cognitive science were reproducible in this population but failed to produce a successful educational curriculum.“We think our findings underscore both the feasibility and the necessity of randomized-controlled field experiments to test frontier cognitive science hypotheses in the field,” said Spelke.Why did the curriculum fail to improve school mathematics, even as it effectively trained intuitive concepts, and how might future studies succeed at this second step?“Our best guess is that our intervention did not increase kids’ performance in school because the gap between intuitive mathematics and formal mathematics is too large, and ordinary conversations and social interactions cannot bridge it in this context,” said Esther Duflo, a professor of economics at MIT and a co-author of the study.“Our ongoing interventions focus on versions of these games that exercise children’s intuitive mathematical abilities while also presenting the primary language and symbols of school mathematics. We should soon learn whether the new curriculum works better. In this respect, field research is no different from basic research: Both require multiple experiments, and learning from failures, to get things right.”This research was funded by the UBS Optimus Foundation and by Harvard’s Foundations of Human Behavior Initiative.last_img read more

Nativity scenes display cross-cultural traditions

first_imgAnnmarie Soller An exhibition of thirty Christmas nativity scenes, crèches, from around the world will be on display from Nov. 19 through Jan. 31, said John Cavadini, professor of theology and director of the Institute for Church Life. The crèches, on loan from the Marian Library International Crèche Collection at the University of Dayton, are spread throughout campus.“Some are in the Eck Center, some are in the main lobby of the Morris Inn, some are in McKenna Hall, some are in the Main Building, some are in the Hesburgh Library concourse,” he said. “Our idea is to have provided not simply an exhibition of artistic work — though that is what it is — but also to provide people the opportunity for pilgrimage, so that they can walk from one building to the other, and they can prayerfully encounter these images of the holy family and the nativity.“It’s probably nowhere more evident the global enculturation of the Gospel, than in the depiction of the nativity of the Lord, which is the third the joyful mystery of the rosary, as in interpreted by people of various cultures of the world, who have embraced this mystery in their heart. And so, in all of these crèches, we’re at once invited into one of the most intimate in a family’s life, the welcoming of a newborn child, and in contemplating this scene, we’re invited into what Christian faith believes to be the most intimate moment between God and creation, the Incarnation.”Rev. Johann G. Roten, S.M., director of research and special projects at the University of Dayton, delivered the opening lecture, entitled, “The Crèche: A Celebration of Christmas and Culture,” for the exhibit on Wednesday night in the Eck Visitors Center Auditorium.Roten said the crèches demonstrate the close relationship between culture and religion.“And indeed, that relationship between culture and religion has always been a very important concern because where does religion begin? Where does culture stop? How do the two combine? Which is influencing the other?” Roten said. “All of these different things we try to develop and to study in and through our nativity collection.”There are three fundamental ways of looking at nativity traditions, which can be categorized as “mountain,” “landscape” or “village,” Roten said.“When you look through what became the oldest and most important of the nativity tradition, which is of Latin origin, a combination of Italy and Spain, through the city of Naples, a couple things come to the forefront, which have a deep theological meaning,” he said.The design of these crèches is such that the nativities are depicted at the bottom of a mountain, Roten said.“The idea being that the divinity, Jesus Christ, had to go through all the strata of human reality in order to get to the bottom of that reality, and therefore be able to assume the whole of that reality,” he said. “It’s a very important idea, and you find it in quite a lot of those different representations of the nativity.”The “landscape” is found in crèches of the German tradition, Roten said.“Nature becomes an important part, because it shows that the nativity is always a miracle,” he said. “And how do you represent the miracle? Difficult, of course to explain, but at least symbolically you can explain it, in showing in that landscape, for instance, an apple tree laden with apples. Now it’s the end of December. How could you explain it? That’s an illustration of the miracle.”The “village” is found in crèches of the French tradition, especially those of the Provence region, Roten said.“All inhabitants of the village would come to the manger,” he said. “The ‘village’ is an expression not only of the global village but also, what we call in theology the ecclesiology of communion. We have on the one hand great unity and on the other great diversity around the baby in the manger.”Tags: christmas and culture, creches, Institute for Church Life, rev. johann g. roten, roten, university of daytonlast_img read more

UPDATE: Teen Reported Missing 11 Days Ago Walks Out of Great Smoky Mountains National Park

first_imgOfficials in Great Smoky Mountains National Park have located a teen who was reported missing 11 days ago after an off trail off-trail hike in the park’s remote southwest corner.According to local news reports, Austin Bohanan of nearby Blount County, Tennessee, walked out of the park on his own today, emerging near a remote backcountry area known as Tabcat Creek around 2:30 P.M.He’s was then transported to a nearby hospital in Maryville, Tennessee.The 11-day search for Buchanan was headed up by rangers on the park’s search and rescue team, officers with the Tennessee Wildlife Resource Authority and individuals with the Backcountry Unit Search and Rescue team (BUSAR). All told their were 19 active members of the search party.“By limiting the number of searchers in the area, rangers have the best chance to find Bohanan quickly,” a news release from the park service said. “Dog teams and trackers can be hampered by additional people in the area when searchers are looking for signs of hiker travel.”Bohanan was reported missing by his stepfather on Sunday, August 13, two days after he last saw him in the off trail area the two were hiking in. Stay tuned for further updates to this story as more details become available.last_img read more

The 3 people you shouldn’t hire

first_imgThere can be a lot of pressure on you when you’re interviewing job candidates, especially if you’re having to replace a great employee. No matter what position you’re hiring for, you want to make sure you find a candidate that’s not only a good fit for the position but a good fit for your team and your company culture. There are a lot of good options to hire, but here are three people you might want to avoid…The (too) quiet person:  It’s not a crime to be a little shy (it’s def better than saying really dumb things), but when a candidate wants to make a good impression, it’s a good idea to have something to say. Look for the candidate who is delivering great answers and asking great questions. If someone really wants to fill your opening, they’ll be prepared with plenty to say.The brown noser: When I was a kid, I used to love reruns of classic sit-coms like Leave it to Beaver. If you’re familiar with the show, then you probably remember Eddie Haskell. He was the guy who was a little sleazy but always turned on the fake charm whenever there were parents around. A job candidate who says exactly what they think you want to hear is definitely not the right person to join your team. It’s usually pretty easy to spot someone who’s faking it. Find someone who feels like a good fit and doesn’t seem deceptive.The Negative Nancy: You would think that anyone interviewing for a job would try to have a positive outlook. For some, they see a job interview as an opportunity to complain about their current/previous workplace. If they have a legitimate reason to complain that may be one thing, but I’d bet they’re probably the type of person who’s going to look for the negative anywhere they work. Think about whether or not you want someone like that on your staff. 5SHARESShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblr,John Pettit John Pettit is the Managing Editor for CUInsight.com.

Lending Perspectives: Preparing your portfolio for the next recession

first_img ShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblr We have now entered year 10 of the recovery since The Great Recession, which is fairly unprecedented territory when it comes to an economic expansion. Many lenders in the industry have already been making preparations the last several years for the next recession. A variety of auto lenders pulled back their sub-prime lending as early as 2016 for fear of the next recession; sub-prime loans typically don’t survive a recession very well.From past experience, some credit unions tend to be a little late to the party, so to speak, when it comes to preparing for a recession. We tend to be act like eternal optimists until we take a serious hit; I’m thinking of the famous Mike Tyson quote about everyone having a plan until they get punched in the mouth. Sometimes, as lenders, we’re in denial that the economy will ever take a breath and experience some contraction. For others, trying to squeeze every drop of loan growth out of the economy is of utmost importance; resulting collection problems are something to worry about next year. Frankly, this has never been a problem for me; I like to joke that I’ve predicted five out of the last three recessions.For those realists who want to start preparing now, how can you be sure your credit union will ultimately be ready? I’ve seen too many unprepared credit unions suffer in a downturn in my 30 years in the credit union movement and, more importantly, heard of too many members affected as their credit union is more focused on fixing their portfolio than lending money. To evaluate your preparedness, honestly assess your credit union in these four areas: continue reading »last_img read more

TZ Bakra is the first in Croatia to organize a licensed Interpret Europe course for guide interpreters

first_imgAware of the fact that the world heritage has been presented to a wider audience for a long time and that the greatest asset for overcoming the tourist isolation of Bakar is its rich natural and cultural heritage, the Tourist Board of Bakar and the City of Bakar have recognized the need for quality education of tourist guides. museum staff and staff in nature parks.Therefore, in cooperation with the first interpretation guide and coach in Croatia and the author of popular “Secret Zagreb” tours, Ivo Silla, they decided to organize a licensed Interpret Europe course “Guide interpreter” which will be held in October and November in Bakar. That’s right In July, the Tourist Board of the City of Bakar filled all places for the Interpret Europe licensed course “Guide interpreter” which will be held in Bakar in October and thus became the first destination in Croatia to independently organize a licensed Interpret Europe course for guide interpreters.Costumed themed tours, visitor centers, storytelling, workshops, ecomuseums – all this is the interpretation of heritage, ie the way in which natural and historical heritage is “translated” into a language understood by the local population of all generations (especially children and youth) and visitors and tourists Interpret Europe is a European professional association that brings together about 500 professionals in the field of heritage interpretation from 45 countries and through a series of courses held by their members in their countries conducts various trainings with the aim of better interpretation of heritage, indispensable. part of cultural tourism.In this way, the Tourist Board of the City of Bakar is actively involved in the development of heritage interpretation in the Primorje-Gorski Kotar County with the desire that Bakar emerges from decades of tourist isolation through interpretive guides and other professionals who will reveal rich Bakar heritage to visitors. which are actually the essence of tourism.”Tečaj in Bakar will be the first Interpret Europe course for interpretive guides in Croatia organized exclusively by Croatian organizers. Although we are one of the smallest tourist boards, and our tourism development lags far behind that in Kvarner, we are proud that we, together with the City of Bakar, organized education which is a prerequisite for the development of quality, strategically oriented tourism in our area. In this context, we are extremely pleased with the recent publication of an article in the newsletter of the Intepret Europe association in which Iva Silla and expert for the promotion of interpreted heritage Silvija Jacić presented activities in the field of heritage interpretation that we launched in Bakar such as Ponikva Educational Trail Walks through history or a program for children called “Little Naval Battle”. We intend to continue and develop all of them, as well as some new ones like this course, even more intensively, into quality tourist products.”Emphasized the director of the Tourist Board of the City of Bakar, Sonja Jelušić Marić.Through 40 hours of theoretical and practical classes, trainer Iva Silla will teach students the skills of interpretive guidance that are achieved through interpretive techniques and methods and the search for unique properties of phenomena and objects. The course also includes non-personal interpretation, understanding groups of visitors with special needs, and learning about sustainability and the use of interpretive criticism. At the end of the course, participants will be trained to plan and perform interpretive guidance, which will raise the quality of their work and bring stronger memories and new experiences to visitors. All guides, participants of the course, after successful passing become certified interpretation guides, and those who are not engaged in leadership will gain useful knowledge about the interpretation of heritage. At the same time, in newsletter of this important European association, a text was published on the increasingly intensive interpretation of the cultural and natural heritage of the City of Bakar, which is becoming its main tourist asset.RELATED NEWS:last_img read more
