Buzzing teaching tool

first_imgBy Sara LaJeunesseUniversity of GeorgiaWasp wrangling may sound like risky business, especially forchildren. Actually, it’s quite safe. So much so that a Universityof Georgia professor is using wasps as a way to teach science.Collaborating with UGA science education colleagues and about 100Georgia middle school science teachers, UGA entomologist BobMatthews has developed 20 classroom activities using “WOWBugs,”wasps so tiny that their stingers can’t penetrate humanskin.”The first lesson is handling the organism,” Matthewssaid. Bug-racing 101Students practice sweeping the bugs across their desks with paintbrushes. In a second lesson, called WOWBug Racetrack, they learnhow to collect and analyze data. They record the time it takesfor the flightless wasps to scuttle from one end of the track tothe other.Matthews and his colleagues have studied these wasps’ biology formore than 30 years. He first recognized their potential asteaching tools when he was in graduate school.”They literally found me,” he said of the discovery that WOWBugshad infested his thesis experiment involving a bee.From this fiasco, Matthews learned of the wasps’ hardiness andshort (24-day) life cycle, which makes them convenient to study.He named thm WOWBugs because of the enthusiasm they generated. For college students, tooWOWBug use at the college level is a bit more involved. Matthewsand postdoctoral associate Jorge M. Gonzalez created four modulesfor freshman biology classes. These modules help students study: * Courtship and aggression behaviors.* Natural selection and heritability.* Ecological interactions, including competition.* Development and polymorphism (having more than one form –short-winged versus long-winged, in the case of females).One of Matthews’ animal behavior classes was taught through theUGA College of Agricultural and Environmental Sciences. Thestudents designed WOWBug experiments for their end-of-termprojects.Vanessa Reynolds, a recent UGA graduate, examined whether femalewasps would choose to lay eggs on a host that had already beenparasitized or go for a “clean” host instead. Although her studyyielded inconclusive results, Reynolds was impressed with theclass.”It influenced my goals,” she said. “Now I’d love to go tograduate school in animal behavior and incorporate that subjectinto a focus in education.”Stories like this make Matthews proud. And Reynolds is only oneamong the many students of all ages who have been wowed by thisbug.”Fifteen years ago, if you had said WOWBugs were going to gonational or international in the next decade or so, I would havesaid you’re crazy,” Matthews said. “But it’s becoming anothermodel organism for classroom use at all levels.”For more information, visit the Web site or emailMatthews at Ant-size non-stinging wasps”They were originally called fast wasps in allusion to theirrapid life cycle,” he said. “Unfortunately, the name didn’t havegood marketing appeal, as it conjured up a quick sting!”Not much bigger than fleas, the parasitic wasps (Melittobiadigitata) prey on many solitary bees and wasps, including muddaubers — large, black wasps that make mud nests.The tiny bugs have some fascinating characteristics. The male,for example “is most un-insect looking,” Matthews said. “He’sblind, his antler-like antennae are grotesquely modified and he’sgot little stumps for wings.”This compromised chap’s pheromones let him do his procreativeduty, however, as long as he can steer clear of other males whowill try to kill him.In any case, teachers are enthusiastic about using WOWBugs.Brenda Hunt of North Habersham Middle School in Clarkesville,Ga., teaches her students how to collect wild specimens byscraping mud dauber nests off the sides of buildings.”I also tell them,” she said, “not to use their mothers’ spatulaswithout permission.”last_img read more

Moody’s: Renewables continue growing at coal’s expense

first_img FacebookTwitterLinkedInEmailPrint分享Financial Times ($):Emerging markets are set to eclipse developed nations next year in their capacity to generate wind and solar power as equipment costs fall and the energy market approaches “peak coal”, according to Moody’s, the credit rating agency.While developed countries have long been leaders in renewable power generation, emerging economies are close to overtaking them, bringing their total installed capacity of wind and solar to 307GW and 272GW — respectively 51 per cent and 53 per cent of global capacity, according to Moody’s calculations.China accounts for the lion’s share of the upsurge. But Middle East and north African countries are scheduled to have installed 14GW in solar plants by the end of 2018 — a seven-fold increase from 2015. Central and South America are also expected to reach 14GW, nearly five times more than in 2015, while India is set to hit 28GW, a jump of nearly six times.“Everyone knows the cost of installing solar and wind energy has been coming down, but recently we have seen prices hitting extreme lows in places such as Mexico, Chile, India and Abu Dhabi,” said Swami Venkataraman, senior vice-president at Moody’s Investors Service. “This fall in costs is definitely changing the calculus of [emerging market] governments, allowing them to pursue renewables much more aggressively,” he added.Another factor is the onset of “peak coal” in the energy market. In 2013, the US Energy Information Administration projected that world coal demand would rise 39 per cent by 2040. Now it is expecting growth of just 1 per cent.More ($): Emerging markets poised to lead pack on renewable energy Moody’s: Renewables continue growing at coal’s expenselast_img read more

The pandemic changed things, but racers still showed up for the Asheville Triathlon

first_imgDuring the swim portion of the race, participants were given a wave start time based on their projected swim time and were given a full minute before the next swimmer entered the pool. “We never had more than 25 swimmers at the pool or on the deck at a time,” said Kirkwood. “Everything was very spaced out from start to finish.”  By most accounts, the race was a smashing success. Eighty-three percent of participants indicated they would come back and do the race again. According to one satisfied participant, “I felt safer racing… than going to the grocery store.”  And all of those cheering fans? Forget about it. “No spectators were allowed at the pool or at the finish line,” Kirkwood said. The pandemic had changed a lot of things, but it couldn’t stop one group of hardcore triathletes from competing this summer. Last Sunday, just over 100 participants showed up at a park in Hendersonville, NC to do something that most athletes used to take for granted: toe the line at an in-person race.  Race participants wore face coverings before and after the event, had their temperatures checked, and stayed socially distant from other participants. Instead of having typical transition zones, which usually include close quarters, participants were asked to transition at their vehicles. The rebooted transition zones “went really well,” said Kirkwood. “[Racers] had plenty of room to set up their things… we also had spaces in between some cars giving additional space.”center_img The Asheville Triathlon, held at a new location in Hendersonville’s Patton Park, is setting an example of what in-person events may look like in the future during the time of COVID-19. “This coronavirus has really forced us to make some big changes in the endurance event industry,” said Daphne Kirkwood, owner of iDaph Events and Race Director for the Asheville Triathlon. “There just isn’t a cookie cutter way to design and produce an in-person event during a pandemic. But I’m really happy with how safely everything turned out.” The winners of this triathlon-like-no-other were Jenn Stanton and Ricky Flynn. Stanton is a pro triathlete from Charlotte, NC and finished with a time of 1:05:22. Stanton, also a pro triathlete from Greenville, SC, completed the race in 58:23.

Aronovitz: Dignity in Law has made a difference

first_img July 1, 2003 Regular News A year ago, Bar President Tod Aronovitz launched the Dignity in Law program, saying he wanted to tell Floridians the whole story about lawyers and the legal system.At the Board of Governors’ May 30 meeting in Key West, he wrote the end to what he hopes is the first chapter of that tale.Dignity in Law had a successful initial year, Aronovitz said, surpassing its goals in many areas and garnering strong support from lawyers and judges. And, he added, the Bar can build on that success in the future. The effort has been approved to continue in the 2003-04 budget, but with reduced funding as Bar staff performs some functions this year that were done previously by rbb Public Relations of Coral Gables, who helped the Bar design the program.The goal of the program was to increase positive stories about the legal system in the media by 50 to 100 percent. At the beginning of the year, only 7 percent of news stories were positive, and 30 percent were negative, Aronovitz said. the end of the year, 19 percent were positive and 11 percent were negative (the rest were judged neutral).The Bar hoped to increase reporting on pro bono activities by 50 percent, and instead got a 200 percent rise, he said, and coverage on judges and what they do rose by 150 percent, well above the 15 to 25 percent initially hoped for.The program also created an online media center that is regularly used by journalists and the public, he noted.Through Dignity in Law, Aronovitz said the Bar was able to publicize, assist, or help sponsor a number of good projects by lawyers and bar associations, including a mentoring program by the Florida Association for Women Lawyers, various celebrations of the 40th anniversary of Gideon v. Wainwright, and a number of individual good works by lawyers.The program also initiated highly creative graphical e-mails for legislators, and those were just recognized with a Bronze Anvil Award by the Public Relations Society of America.Improving the public perception of the legal system is key with helping the Bar in its legislative activities, Aronovitz said. He noted that a state representative recently announced a constitutional petition initiative aimed at capping all contingency fees in tort and workers’ compensation cases at $75,000.“There are so many people out there right now who want to attack our profession,” he said. “To help our legislative team, to help our next president and our successor next president, I say this program is essential and helps all lawyers in the state.. . . “Keep believing and keep talking about the good things we do. We now have a stepping stone from which to go forward.” Aronovitz: Dignity in Law has made a differencecenter_img Aronovitz: Dignity in Law has made a differencelast_img read more

The World Tourism Organization has launched a program to monitor the recovery of tourism

first_imgAs more and more countries around the world ease travel restrictions, World Tourism Organization (UNWTO) has launched a new program to monitor the recovery of tourism – Tourism Recovery Tracker, in support of global tourism. An extensive tourism dashboard is the result partnerships of international organizations and the private sector, covers key indicators of tourism performance by months, regions and subregions, and enables recovery comparison sectors worldwide and real-time industries. According to the latest data from the World Tourism Organization, a sharp drop in demand for international travel during the first six months of this year has led to a loss of as much as 440 million international arrivals and eye $ 460 billion income from international tourism. That’s about it five times the loss in revenues from international tourism from that recorded 2009 in the midst of the global financial crisis. Source: UNWTO UNWTO’s Tourism Recovery Tracker is available free of charge and is a joint effort of a group of partners, including the International Civil Aviation Organization (ICAO), ForwardKeys, STR, Sawyer and AIRDNA. “Tracker” collects everything relevant data providing governments and private companies with the ability to monitor the recovery of tourism at the global and regional levels, along with information on major destinations for international tourism. That’s right on one place can find data on international tourist arrivals, seat capacity on international and domestic airlines, air travel reservations, hotel searches and reservations, occupancy rates and demand for short-term rentals.last_img read more
