Survey of Saturn Z-mode Emission

first_imgBecause of the role of Z-mode emission in the diffusive scattering and resonant acceleration of electrons, we conduct a survey of intensity in the Saturn inner magnetosphere. Z-mode is primarily observed as “5 kHz” narrowband emission in the lower density regions where the ratio of cyclotron to plasma frequency, fc/fp > 1 to which we limit this study. This occurs at Saturn along the inner edge of the Enceladus torus near the equator and at higher latitudes. We present profiles and parametric fits of intensity as a function of frequency, radius, latitude, and local time. The magnetic field intensity levels are lower than chorus, but the electric field intensities are comparable. We conclude that Z-mode wave-particle interactions may make a significant contribution to electron acceleration in the inner magnetosphere of Saturn, supplementing acceleration produced by chorus emission.last_img

Ecophysiology and ecological limits of symbiotrophic vesicomyid bivalves (Pliocardiinae) in the Southern Ocean

first_imgGeothermal energy provides an important resource in Antarctic marine ecosystems, exemplified by the recent discovery of large-sized chemosymbiotic vesicomyid bivalves (subfamily Pliocardiinae) in the Southern Ocean. These clams, which we identified as Archivesica s.l. puertodeseadoi, have been reported as dead shells in areas previously covered by Larsen A and B ice shelves (eastern Antarctic Peninsula) and as live animals from active hydrothermal sites in the Kemp Caldera (South Sandwich Arc) at depths of 852–1487 m. Before, A. puertodeseadoi was known only from its type locality in the Argentine Sea, so we considerably extend the range of the species. Observations taken by remotely operated vehicle (ROV) footage show that the clams can live buried in sediment, or epilithically on the surface of rocks in diffuse geothermal flow. Experimental respirometry was conducted at surface pressure on individual bivalves acclimated to either their habitat temperature (4 °C) or elevated temperature (10 °C). The range of standard metabolic rates, from 3.13 to 6.59 (MO2, μmol O2 h−1 g−1 dry tissue mass), is similar to rates measured ex situ for other species in this clade, and rates did not differ significantly between temperature groups. Taken together, these data indicate a range of ecophysiological flexibility for A. puertodeseadoi. Although adapted to a specialist mode of life, this bivalve exploits a relatively broad range of habitats in the Southern Ocean: within sulphidic sediments, epilithically in the presence of diffuse sulphidic flow, or in deep methane-enriched seawater trapped under ice.last_img read more

Press release: PHE scientists lead science workshops for 1,800 pupils

first_img It’s important that the current generation of scientists informs and inspires the next generation, and shows young people the range of routes and opportunities they can pursue within world-leading UK science. We are thankful for the scientists taking part in British Science Week workshops across the country, and hope that their efforts encourage the pupils to consider a career in science as a viable and exciting option. As part of this year’s British Science Week, 1,800 pupils from 10 schools across England are being given the opportunity to take part in interactive science workshops hosted by Public Health England (PHE) scientists.From pupils extracting DNA from their own cells using household products, to a science and health-related game of Pictionary and quizzes on air pollution, the aim of these workshops is to inspire the young people to consider a career in science and showcase the variety of areas within science they could pursue.British Science Week is an annual 10-day event, with this year being its 24th year running. It encourages organisations, professionals in the science sector, science communicators and the general public to hold events that get people involved in scientific activities.This year, PHE is expanding its reach to 10 schools across 3 regions: the North (Manchester, Salford), South West (Bristol, Cheltenham and Torquay) and South East (Harlow). During the week, there will be 25 PHE scientists leading interactive science workshops for pupils aged 13 to 14 years old.The scientists taking part specialise in a range of disciplines, including toxicology, microbiology, environmental public health, microscopy, vaccine research and epidemiology.Duncan Selbie, Chief Executive of PHE said: British Science Week is an annual event and in 2018 takes place between 9 to 18 March. Schools attending the sessions are: Burnt Mill Academy Forest Hall School Mark Hall Academy Stewards Academy Passmores Academy Torquay Academy Fairfield School All Saints’ Academy All Hallows R.C. High School Walkden High School Public Health England exists to protect and improve the nation’s health and wellbeing, and reduce health inequalities. We do this through world-leading science, knowledge and intelligence, advocacy, partnerships and providing specialist public health services. We are an executive agency of the Department of Health and Social Care, and a distinct organisation with operational autonomy. We provide government, local government, the NHS, Parliament, industry and the public with evidence-based professional, scientific expertise and support. Follow us on Twitter: @PHE_uk and Facebook: Sarah Robertson, Senior Environmental Health Scientist at PHE said: I speak for all of the scientists involved when I say that we are excited to take part in British Science Week and showcase just a few of the many disciplines within science to the students. Although a large proportion of our time is dedicated to research, outreach work such as these interactive workshops is also our responsibility, particularly to highlight the breadth of our roles to young people. Science and research are imperative in our world and we must ensure that the future workforce continues to be made up of talented and passionate individuals. PHE is in the process of creating a world-leading centre of excellence for public health research, improvement and protection, and a new headquarters, at the vacant GlaxoSmithKline site in Harlow. This will involve relocating facilities from Porton in Wiltshire and Colindale in north London, as well as the current central London headquarters. PHE Harlow is expected to be fully operational by 2024.Backgroundlast_img read more

Life, reflected in the dead

first_imgChurchyard burial, tombstones, cremation, open caskets, epitaphs. Whatever the custom or religion, human beings expend vast amounts of energy and attention caring for the dead.Why?That was the simple yet profound question audience members were asked to grapple with Tuesday afternoon at a lecture hosted by the Radcliffe Institute for Advanced Study.The answer depends less on religious or metaphysical viewpoints, said Thomas W. Laqueur, professor of history at the University of California, Berkeley, than on a primordial set of ethical obligations played out over thousands of years across countless cultures.The story of why Westerners care for the dead in many ways begins with Diogenes the Cynic, who lived in the fourth century B.C. He said the dead should not be cared for at all, and wanted his own body tossed over the walls and “ostentatiously returned to nature.” In nature, the human body is nothing, and it makes no difference what we do with it, he claimed.“Diogenes’ arguments had many admirers through the centuries, including, implausibly, St. Augustine,” Laqueur said. “But his answer remained culturally and emotionally impossible.” Indeed, the history of much of human culture and thought can be written in our resistance to Diogenes, Laqueur said, “not because of particular beliefs, but because of a primal idolatry — the need to make something live out of something we know to be dead.”We know the dead body to be just matter, so why is Diogenes’ answer so unsatisfying? One set of answers depends on the claim that we have a primal aversion to the uncared-for dead body, Laqueur said. Simply put, the dead body is dangerous.Clergymen in the 18th century thought that “the dead naturally tend to destroy the life of others,” Laqueur said. “The natural spirit of life has an aversion to the dead body … which is why he simply can’t toss it away, but it must be put somewhere safely out of sight that is unlike the detritus of the stockyard.”In the early 17th century, Hugo Grotius, the father of modern law, concluded that the denial of burial was a just cause of war. “The right to burial is common to all civilized nations, and it is evidence of our common nature of compassion, religion, and humanity,” he wrote.Later, care for the dead became a sign of man’s emergence from the world of nature into the world of culture. The 20th century philosopher Hans-Georg Gadamer called it “the fundamental phenomenon of being human.”But it was not only the repulsion from the dead body that drove Western culture to properly care for it. It was also an immense human need that the rituals of burial fulfilled.Looking through an anthropological lens, “The dead do work for the living,” Laqueur said. “The dead are dead. But we need them to do the work that they do. We need them more than they need us.”We have a primal need to endlessly invest a dead body with meaning, Laqueur said. “Through the dead, the human past speaks to us.”In 1809, the philosopher William Godwin wrote, “The enormity of death is the greatest of earthly calamities… Loss is perhaps greater in him who survives than in him who dies, not because the dead are comfortably at the mercy of god … but because the dead are no more than they were before they were unborn.”But even Godwin — who was as close to an atheist as one could be in the late 18th century — tried to bridge the divide between the living and the dead with attention to the material body, Laqueur said.“The corpse is the great paradigmatic reminder set for us by the system of the universe that we are of degraded nature, and humble origins, that we are mortal, and that there is an abyss between the living and the dead. We cast bodies back into the ground as a token of this truth, yet the corpse remains strangely still the person it was, lacking only what seems so little yet so great, the breath of life, the rosy you. The corpse and the person are not irrevocably sundered.”Bridging the divide between the living and the dead continues to compel us to care for them. Laqueur ultimately places his beliefs in the camp of the art critic David Hickey, who wrote, “We are mortal creatures who miss our dead friends and thus can appreciate levitating tigers and portraits by Raphael for what they are: songs of mortality sung by the prisoners of time.”“Largely beyond metaphysics, the dead body conjures with this sort of magic,” Laqueur said. “And from my modern secular perspective, it’s a magic we can still believe in.”Much of Tuesday’s lecture was drawn from Thomas W. Laqueur’s forthcoming book, “The Work of the Dead,” both a social history of what people in the past did with their dead and a cultural history about what their actions and attitudes meant. <a href=”” rel=”nofollow” target=”_blank”> <img src=”” alt=”0″ title=”How To Choose The Correct Channel Type For Your Video Content ” /> </a>last_img read more

Former NFL player lectures on role of God in his life

first_imgTo Tim Brown, the Heisman Trophy and the Hall of Fame induction are just means to the end of speaking to men and women about what it means to be an authentic person whose life is in line with God’s plan for them.Brown, a former Notre Dame football player and NFL receiver, gave the keynote lecture of “StaND Against Hate Week” titled “The Making of a Man” on Tuesday evening in DeBartolo Hall. He spoke about his own life and the lessons it taught him about manhood, faith and parenting.Wei Lin | The Observer “I want nothing more than for men to understand what God wants for them,” he said. “That’s why I wrote my book, and that’s why we talk about the things we talk about.”Brown said he used to undertake his morning routine without turning the lights on because he could not face himself in the mirror. Now, because of a series of epiphanies that occurred over the events of his life, he can hold his head high.“There is no way that you can be your authentic self, in my opinion, without God being involved in your life,” Brown said. “We may be educated, but I know a lot of educated people without God in their lives who are out there making some stupid decisions.”Brown said role models play an integral role in the formation of young people and can influence how they interact with other people for the rest of their lives.“I can tell just as clear as day after speaking with young men for two or three minutes who has good role models in their lives,” Brown said.“As men, we have to understand that our kids are watching,” he said. “My son will tell you now that he was watching me when he was eight years old. He was waiting for me to say something I wasn’t supposed to say or do, something that would set a bad example, and I never did.”Brown said part of the reason he takes speaking opportunities is he wants as many people as possible to hold him accountable for his actions.“Sometimes we don’t want people in our lives telling us what to do because we think we have it all, and we think we know it all,” he said. “But you have to have people on this earth that you can lock into. You have to surround yourself with good people who will hold you accountable.”Brown said he would not have achieved all he has if it were not for former Notre Dame football head coach Lou Holtz and his belief in Brown both as an athlete and as a man.“It wasn’t like he was patting me on the back the whole time and telling me I was okay,” Brown said. “There was a lot of criticism, but with criticism comes correction.”Brown said parents should stand up for their kids when being attacked or scrutinized unfairly, but they should also be willing to let them take responsibility when they make mistakes.“When I see these fathers take up for their kids when their kids are obviously wrong, I can tell that’s going to be a problem,” he said. “We’ve seen it in college sports, and we’ve seen it in professional sports.”Brown said young people have the world at their fingertips, but the current state of the world makes it difficult to avoid temptation and make the correct decision.“If you don’t go to church, go to church. Mom and dad can’t come to college with you or go to the NFL with you,” he said. “At some point, you’re going to need a conscience in your head telling you what you should and shouldn’t be doing.“The only type of conscience that can provide that is a godly conscience, but if you’ve never heard it, and you don’t know anything about it, then it won’t be there for you when you need it.” Tags: StaND Against Hate Week, Tim Brownlast_img read more

Unhappy trails

first_imgBy Sharon OmahenUniversity of GeorgiaGeorgia’s drought has had many effects. One little but truly annoying one is to drive Argentine ants indoors.University of Georgia experts say Argentine ants aren’t hard to identify. “They’re the ones that travel in trails into kitchens, offices and bathrooms,” said Dan Suiter, an entomologist with the UGA College of Agricultural and Environmental Sciences. “If you have them, you definitely know it.”Argentine ants are small, just an eighth of an inch long. Native to South America, they were accidentally introduced into the United States more than 100 years ago in New Orleans coffee shipments. They have since spread across the Southeast and into southern California and Hawaii.”They’re one of the most pestiferous and most difficult-to-control ants in the U.S.,” Suiter said. “A single colony can consist of hundreds of thousands of ants.”InvadersSuiter says the tiny pests travel indoors in search of food and water. Although they’re much more of a problem in the summer, they do come indoors in the winter, too.In the winter, Argentine ants move inside to survive the cold. They live inside closed spaces such as walls until spring, when they move outside. By fall, their colonies have grown to a peak.”When we encounter a drought, like now, while the colonies are growing, they will readily come inside,” Suiter said. “As temperatures begin to cool, they will re-enter structures to survive the cold. And next spring, the process will start all over again.”You can reduce your chances of having these ants in your home by following these tips: Rinse all drink cans before placing them into the garbage or recycling bin.Empty garbage containers often.Don’t leave food or drinks out. “These ants can find a Coke can with just a little syrup left in it,” Suiter said. “They love sugar, and they’ll show up by the thousands literally overnight.”When it comes to controlling the tiny, unwanted guests, Suiter doesn’t recommend any over-the-counter insect killer.”There aren’t a lot of good products out there for homeowners to use,” he said. “You can spray the ants and get what we call the revenge factor. You kill a lot of ants that way. But you’ll never get rid of them, because you haven’t hit the nest, where all the queens are.”The answerSurprisingly, the answer lies in indoor baits. Suiter recommends Terro bait, a liquid you can buy at most home-improvement and lawn-and-garden stores. Another effective bait, he said, is Combat Ant-Killing Gel.”It’s available in a syringe so you can put small dabs anyplace you see ants,” he said. If you’re desperate, call a professional pest control company for help.”There is one product, Termidor, that professionals have access to that performs well against Argentine ants,” Suiter said. “It’s a spray for use outside the home and is not labeled for indoor use.”For more information on controlling pests, call your local UGA Cooperative Extension agent at 1-800-ASK-UGA1.(Sharon Omahen is a news editor with the University of Georgia College of Agricultural and Environmental Sciences.)last_img read more

Former credit union board chair indicted

first_img continue reading » 18SHARESShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblr A former board chair of a Virginia credit union was indicted Thursday on 20 felony charges of forgery, check forgery and ID fraud.Mark M. Whitaker served as board chair of the $101,630 New Bethel Federal Credit Union in Portsmouth, Va. from at least 2012 to 2015 when the credit union liquidated because of its poor financial condition. The 172-member credit union, chartered in 1978, was associated with the New Bethel Baptist Church also in Portsmouth where Whitaker is an associate pastor. He also is a Norfolk city council member.The indictments identified three victims, including Malinda Starkley who also served on the New Bethel FCU board of directors as its treasurer from 2012 to 2015, NCUA documents show. Starkley also is listed as a trustee and deacon of the New Bethel Baptist Church.She was a victim of fourteen of the 18 charges of forgery and forged checks. The indictments did not divulge the total amount of the forged checks. All of the crimes committed against Starkley occurred on Aug. 23, 2013 while the credit union was operating, according to the indictments.last_img read more

3 easy ways for credit unions to get started with marketing automation

first_imgYou’ve probably heard of marketing automation, and you may already be dabbling in it. But chances are, the prospect of implementing a comprehensive marketing automation strategy makes you feel overwhelmed. You’re not alone. According to the Digital Growth Institute, more than two-thirds of banks and credit unions don’t currently take advantage of automated marketing technology. Here’s the good news: You don’t have to go all in all at once. These community banks and credit unions are starting small when it comes to marketing automation, but already they are seeing impressive results. Here’s how you can, too:1. Begin building and segmenting your email list by leveraging in-person eventsA personal touchpoint with a prospective member is a huge opportunity—don’t let it go to waste! Truity Credit Union asks attendees at informational events fill out questionnaires, and the credit union uses this data to segment its lists based on interest in various financial services. Truity then sends out customized email campaigns based on a prospect’s self-reported interests. Before, Truity’s emails had an 18 to 25 percent open rate, but after implementing a marketing automation strategy, open rates jumped up to 36 percent and have been as high as 54 percent.Credit card applications have also skyrocketed. Kyle Dahlgren, Assistant VP of E-commerce at Truity explains, “We did pretty well with those in the past, but now they’re sensational… The first week we went live, we were flooded with hundreds of new credit card applications. That’s a good problem to have.”2. Incentivize website visitors to give you their email address If you don’t have a way to follow up with prospects, your marketing automation efforts will not go very far. BNB Bank’s recently launched website doesn’t offer online account opening or loan applications, but it still gives prospective customers a clear next step from its product pages—that is, to speak with a banker or lender. A streamlined form then captures only the critical information while providing valuable insights to the bank on the specific products or services the prospect is interested in. Not only do prospects who fill out the form have an opportunity to experience an in-person touchpoint with the bank, but the bank’s integrated marketing automation tool can now deliver content that speaks directly to their areas of interest.   Consider other reasons a prospect might provide you with an email address and incorporate the relevant tools or forms into your site. Perhaps you can develop helpful content, like a home-buying or car-buying guide, to be delivered via email, or perhaps an online scheduling tool for branch appointments can help to capture critical information. You could even have some fun with a financial fitness quiz or online poll. 3. Send triggered email series to welcome new customers or membersOf course, marketing automation shouldn’t stop when a prospect becomes a customer—in fact, at this point, nurturing the relationship becomes all the more critical. While “welcome series” for new customers are nothing new, surprisingly few financial institutions have an active onboarding campaign in place. First Tech Federal Credit Union has created an award-winning onboarding experience for new members during their first month of membership. The campaign combines emails introducing members to First Tech’s values and mission with offline actions such as scheduling follow-up phone calls to further nurture the relationship.With this campaign, First Tech has increased the number of members who opened a checking account by almost 20 percent, and the credit union has created similar improvement in other categories, including enrollment in direct deposit, use of e-statements, average deposits, and use of online banking. First Tech’s marketing team considers marketing automation something of a “secret weapon” for delivering the right communications at the right time.Many credit unions believe that the success of marketing automation hinges on investing in the right software. It’s an important piece of the puzzle, to be sure, but whichever tool you use, the real magic of marketing automation lies in collecting and leveraging the relevant information. Communications and repetitive tasks might now be automated, but that doesn’t mean they should be on autopilot. Instead of “setting it and forgetting it,” the key to success is to start small, consistently monitor your results, adapt your approach, and work toward your next goal. 5SHARESShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblr,Kerala Taylor Kerala Taylor is a Digital Strategist at PixelSpoke, an award-winning certified B Corp that works with credit unions to create delightful online experiences.
