The university has decided to reward its high-achieving students the best way it knows how — by letting them do more work in multiple fields of study.The Academic Achievement Award, introduced Sunday by the Office of Undergraduate Programs, allows students who have at least a 3.75 grade point average and are pursuing a double major or minor to take up to 20 units for the price of 18 units. Without the award, every unit more than 18 costs $1,299 .“The goal is to make it easier for students with excellent academic records to graduate with multiple programs of study and still graduate in four years,” said Gene Bickers, vice provost of undergraduate programs. “If they are capable of doing 20 units in a semester, then we’ll make it possible without an extra cost.”In addition to holding a 3.75 GPA at the time they apply for the award, students also must have completed 32 units, including at least 12 units at USC, and must be able to demonstrate that taking additional units would contribute toward earning multiple degrees.Students must also have declared a double major, a double degree or any form of a major-minor combination by the time they submit their applications. The diversity of the fields of study does not matter.Unlike the Renaissance Scholarship, another award for students who study diverse fields that is awarded to 10 graduating seniors annually, the achievement award is not a competition. If all criteria are met, a student is guaranteed an award every semester an application is submitted.Most merit-based awards, such as Trustee and Presidential Scholarships, are awarded before students commit to USC. The new award aims to recognize the efforts of transfers, spring admits and students who did not receive a scholarship. Bickers did note that transfer students are substantially less likely to pursue multiple studies than freshmen admits.Bickers acknowledged the difficulty of determining how many students are interested in multiple programs of study, but he expects about 200 students to receive the award for the fall semester.Ray Gonzales, senior director of research and reporting for the Office of Academic Records and Registrar, said 775 out of 16,000 undergraduates are enrolled in more than 18 units currently.The university sent an e-mail Sunday to the more than 2,500 students with 3.7 GPAs and above, announcing the new award. Of those, only about 1,000 students have already declared multiple programs of study. Bickers said within 24 hours, his office received about 50 applications.Applications will be processed beginning in mid-April. Bickers said students who apply before April 30 would be notified of an award decision before the end of finals.Students have until Aug. 20, the Friday before fall classes begin, to apply for the award. More students could become eligible for the award after this semester’s grades are finalized, Bickers said. A student’s eligibility is based on his GPA when he applies — if a student’s GPA falls below 3.75 after they are granted the award, he will still receive the funding.Bickers said students who believe they meet or will meet the requirements should register for 19 or 20 units before receiving an award notification. Students have until the third week of classes before they are billed for their units.To accommodate the new program, USC’s schools have agreed to accept slightly less money per unit to redistribute tuition revenue to the achievement award. While 30 percent of tuition funds financial aid, 70 percent typically goes back to the schools, depending on the number of units taken within each school. The latter percentage will now marginally decrease.Scott Macklin, a junior majoring in astronautical engineering, said he had been considering completing a minor but had trouble fitting it into his schedule without taking more than 18 units.“I really would have liked the opportunity to minor in something unrelated to engineering, and this may have been enough encouragement to do that,” he said.Lucas Biging, a junior majoring in geography, said although he does not qualify he would have pursued an extra degree if he could have done it in less than five years.“If I could swing a big course load of 20 units and manage a 3.75, then I don’t see any reason why not to pursue this opportunity,” he said. “A little tuition break makes sense to me.”Kelsey Ezer, a freshman majoring in business administration who will qualify for the award at semester’s end, said taking five or six classes seems tough, but she would consider it if needed.“It’s a good idea if it can get you to graduate in four years if you couldn’t otherwise while taking a minor,” she said.Bickers said the idea is not to push students to do too much but to help the students who can still excel while completing multiple objectives.
Why engineer things from scratch, when we can imitate nature? Two recent examples come from the world of insects. A press release from UC Berkeley begins, “Using the eyes of insects such as dragonflies and houseflies as models, a team of bioengineers at University of California, Berkeley, has created a series of artificial compound eyes.” (Emphasis added in all quotes.) Insect eyes use thousands of facets to get a wide field of view without distortion. How can humans use this technology? “Potential applications include surveillance; high-speed motion detection; environmental sensing; medical procedures, such as endoscopies and image-guided surgeries, that require cameras; and a number of clinical treatments that can be controlled by implanted light delivery devices.” Anyone who has missed swatting a fly knows that the insects have these first three applications down pat. The authors published their work in Science this week.1 Human committees have a hard time arriving at a consensus about what is the best solution to a problem. Maybe they should learn from bees. Ten thousand of them swarming chaotically somehow converge quickly on a solution to the problem of the best location for a new hive. A press release from Cornell University says that “they have a unique method of deciding which site is right: With great efficiency they narrow down the options and minimize bad decisions.” How? By coalition building till a quorum develops, the article explains. The scientists found that bees use their famous “waggle dance” not only when shopping for food, but when scouting for real estate. The researchers watched 4,000 scouts report back to the hive from various directions. The superior site usually was not the first one chosen. In a 16-hour process, the swarm came to agreement and found the best solution. “This is a striking example of decision making by an animal group that is complicated enough to rival the dealings of any department committee,” said Thomas Seeley, Cornell biologist. What can managers take home from this nature lesson? Include an open forum of ideas, and employ frank discussions and friendly competition. This quorum-setting method of aggregating independent opinions might help “achieve collective intelligence and thus avoid collective folly.”1Jeong et al., “Biologically Inspired Artificial Compound Eyes,” Science, 28 April 2006: Vol. 312. no. 5773, pp. 557 – 561, DOI: 10.1126/science.1123053.Funny, honey; none of these articles mentioned evolution, but they seemed to have no problem using the word design.(Visited 16 times, 1 visits today)FacebookTwitterPinterestSave分享0
21 January 2013Giniel de Villiers and Dirk von Zitzewitz, driving a South African-built Toyota Hilux 4×4 for the Toyota Imperial Team, finished second overall in the Dakar Rally, which ended in Santiago, Chile on Saturday afternoon. Broadlink KTM Rally Team rider Riaan van Niekerk was awarded the trophy for top rookie in the motorcycle race after finishing a very impressive 13th overall.It was their second successive podium finish in an Imperial Toyota Hilux in the world’s longest and toughest motor race – they were third last year at Toyota Motorsport’s first attempt – and they won the T1.1 class for petrol-powered 4×4 improved cross-country vehicles for the second year in succession.Petrol leaderLast year’s third place was the first podium place for a non-diesel since 2009 Dakar Rally. This year’s result was the best ever for a Dakar 4×4 vehicle powered by a petrol engine in the history of South American-based Dakar rallies.After 14 special stages in Peru, Argentina and Chile covering more than 4 000 kilometres and two crossings of the Andes Mountains at an altitude above 4 000 metres, the 2009 Dakar champions finished 42 minutes behind defending champions Stephane Peterhansel and Jean Paul Cottret of France in a Mini.Third overall in the general classification for cars were Russians Leonid Novitskiy and Konstantin Zhiltsov in another Mini, 46 minutes behind De Villiers and Von Zitzewitz.Final stageSaturday’s final stage of 128 kilometres of fast tracks between La Serena and Santiago was won by Peterhansel’s Spanish team-mate Nani Roma and co-driver Michel Perin of France in another Mini, from Argentine Orlando Terranova and Portugal’s Paulo Fiuza in a BMW X3 and Argentinians Lucio Alvarez and Roland Graue in another South African-built Toyota Hilux. De Villiers and Von Zitzewitz were fourth.Three other Toyota Hilux 4x4s built by Kyalami-based Hallspeed for Toyota Motorsport were among the 92 finishers out of the 153 cars that started the rally in Lima, Peru, on 5 January.Alvarez and Graue were classified 10th, the Australian/British duo of Geoffrey Olholm and Jonathan Aston were 11th and Poland’s Adam Malysz and Rafal Marton were 15th.‘A great result’“This is a great result for Toyota Motorsport and the all-South African Toyota Imperial Team,” said team principal Glyn Hall. “It was achieved without any significant mechanical problem and it is testimony to the legendary toughness and reliability of South Africa’s best-selling bakkie.“This was a mighty performance by Giniel and our honorary South African, Dirk, and also by every single member of our technical and support crew, whose dedication and commitment contributed massively to this proud achievement. I am privileged to be manager of this fine team.”‘A victory for us’De Villiers commented: “It was a difficult race, as usual. The Dakar is never easy. Second place – that counts as a victory for us.“Last year we exceeded our expectations by far and this year, who would have believed we would better our third place then?“We were a bit unlucky at times, which prevented us from finishing a bit closer to Stephane. You need a bit of luck in the Dakar. You need the wind to blow in your favour. It wasn’t always the case for us, but that’s racing,” De Villiers said.Stronger competition“The competition this year was a lot stronger than in 2012. There were numerous candidates for victory; we were the underdogs. Our reliability enabled us to not only beat the Dakar, but also made the decisive difference.“Toyota’s three-year programme got off to a first-class start. We can now move on and maybe do even better next year. I’m looking forward to that.”Von Zitzewitz added: “The saying ‘To finish first, you first have to finish’ was originally coined in Formula One, but it applies even more to the Dakar. I am incredibly proud of this result. Simply put, this Dakar was challenging, but we were up to it.”MotorcylesBroadlink KTM Rally Team star Riaan van Niekerk finished his first Dakar Rally with 22nd place on the final stage, just over eight-and-a-half minutes down on stage winner Ruben Faria. Brett Cummings, on a Honda, came home in 28th spot, and Darryl Curtis ended 60th after towing American Kurt Caselli.The Dakar was a huge triumph for Van Niekerk. He was consistent throughout and became stronger as the event progressed. Joan Barreda won four stages, but finished in 17th place, behind Van Niekerk, which showed the “steady does it” approach adopted by the South African star pays off in the Dakar.Van Niekerk’s team-mate Darryl Curtis had a more eventful race, but battled his way through a number of spills to finish in a fighting 32nd place. Cummings finished 43rd.Fifth titleKTM’s Cyril Despres claimed his fifth Dakar title, finishing just 10 minutes and 43 seconds ahead of final stage winner Faria and 18 minutes and 48 seconds ahead of Chile’s Francisco Lopez. It was the closest finish since 2005 when Despres won for the first time, ahead of Marc Coma and South African legend Alfie Cox.South African quad rider Sarel van Biljon was a force to be reckoned with, recording three stage victories, including the final stage. His position in the overall standings was unfortunately undermined by a disastrous stage nine, which led to him finishing only 21st overall.The overall title went to Argentina’s Marcos Patronelli for a second time. His brother Alejandro won in 2012.SAinfo reporterWould you like to use this article in your publication or on your website? See: Using SAinfo material
“It will be an exciting meeting,” World Economic Forum founder Klaus Schwab said of the organisation’s 2014 annual Davos gathering, at a news conference on Wednesday 15 January. “It will be different from last year’s, because it will not be overshadowed by one single crisis.”Schwab characterised the context of the 2014 meeting by three things: cautious optimism, diminished expectations, and many known unknowns.Watch the full 56-minute pre-meeting press conference here:
The American Southwest is running out of water. For a powerful reminder, if any is needed, of why builders in Western states should integrate water-conservation strategies in all new buildings, check out a new book by James Lawrence Powell, Dead Pool: Lake Powell, Global Warming and the Future of Water.Powell’s message is stark: according to scientists’ best predictions, millions of Americans living in the Southwest will face unprecedented water shortages in the next few decades. The rapid growth of Southwestern cities was made possible by two huge Colorado River projects undertaken by the U.S. Bureau of Reclamation: the Hoover Dam, completed in 1935, and the Glen Canyon Dam, completed in 1966.Although the two reservoirs created by these dams, Lake Mead and Lake Powell, allowed millions of Americans to move to the desert, Colorado River water is now being consumed at such a high rate that the reservoirs are rarely full. At the end of October 2007, Lake Powell and Lake Mead each held only 49 percent of capacity.For decades, the Bureau of Reclamation’s predictions of Colorado River flow have been based, to put it charitably, on wishful thinking and junk science.Powell shows how federal bureaucrats and politicians used flagrant exaggerations to promote dams on the Colorado River. Powell writes, “As experience accumulated, it became apparent that not only did the agency routinely underestimate costs, it did so by at least a factor of two.”The taxpayers ended up footing the bill for dams that supply farmers with subsidized water that costs far more to deliver than the value of the resulting harvests justifies. Powell concludes that these massive Western water projects amounted to “a kind of hydraulic Ponzi scheme.”During most of the twentieth century, the Bureau of Reclamation, using language that harkened back to the early… Start Free Trial Already a member?

About the authorPaul VegasShare the loveHave your say Arsenal boss Emery expects emotion, passion for Spurs Cup clashby Paul Vegas10 months agoSend to a friendShare the loveArsenal boss Unai Emery expects more emotion tonight for their Carabao Cup quarterfinal clash with Tottenham.Emery saw plenty of passion in his first encounter with Tottenham on December 2, a game that swung this way and that before it was settled by Arsenal’s stirring second-half performance.“I think showing emotion is very important,” said Unai. “I think football is emotion. And in a derby, maybe this emotion is greater.“When you win it’s amazing, when you lose it’s horrible. But respect is very important. We can show this emotion with respect when we are playing, but also when they scored against us, they can show their emotion with their supporters. But with respect. “We need to show this emotion when we are playing, when we are winning, because I think football needs this passion.“I say to [the players] that, in every match, we need to respect the opposition. Against Southampton, against Tottenham, against Manchester United, against Huddersfield, it’s the same. This respect is by playing with a big motivation and a lot of excitement to win against them. “We must respect this emotion in every moment. But the emotion is not bad. I think showing our emotion, the players, the fans and me, is good. But every time we must respect them.”

Today, the paper has been massively written and revised with the help of more than 40 online collaborators, most of whom contributed enough to become co-authors.The updated study, “Opportunities and obstacles for deep learning in biology and medicine,” was published April 4, 2018 in the Journal of the Royal Society Interface.Gitter, of the Morgridge Institute for Research and University of Wisconsin-Madison; and Greene, of the University of Pennsylvania; both work in the application of computational tools to solve big challenges in health and biology. They wanted to see where deep learning was making a difference and where the untapped potential lies in the biomedical world.Gitter likened the process to how the open source software community works.”We are basically taking a software engineering approach to writing a scholarly paper,” he says. “We’re using the GitHub website as our primary writing platform, which is the most popular place online for people to collaborate on writing code.”Adds Gitter: “We also adopted the software engineering mentality of getting a big team of people to work together on one product, and coordinating what needs to be done next.”The new authors frequently provided examples of how deep learning is impacting their corner of science. For example, Gitter says one scientist contributed a section on cryo-electron microscopy, a new must-have tool for biology imaging, that is using deep learning techniques. Others rewrote portions to make it more accessible to non-biologists or provided ethical background on medical data privacy.Deep learning is part of a broader family of machine learning tools that has made breakthrough gains in recent years. It uses the structure of neural networks to feed inputs into multiple layers to train the algorithm. It can build ways to identify and describe recurring features in data, while also being able to predict some outputs. Deep learning also can work in “unsupervised” mode, where it can explain or identify interesting patterns in data without being directed.One famous example of unsupervised deep learning is when a Google-produced neural network identified that the three most important components of online videos were faces, pedestrians and cats—without being told to look for them.Deep learning has transformed programs like face recognition, speech patterns and language translation. Among the scores of clever applications is a program that learns the signature artistic traits of famous painters, and then transforms everyday pictures into a Van Gogh, Picasso or Monet.Greene says deep learning has not yet revealed the “hidden cats” in healthcare data, but there are some promising developments. Several studies are using deep learning to better categorize breast cancer patients by disease subtype and most beneficial treatment option. Another program is training deep learning on huge natural image databases to be able to diagnose diabetic retinopathy and melanoma. These applications surpassed some of the state of the art tools.Deep learning also is contributing to better clinical decision-making, improving the success rates of clinical trials, and tools that can better predict the toxicity of new drug candidates.”Deep learning tries to integrate things and make predictions about who might be at risk to develop certain diseases, and how we can try to circumvent them early on,” Gitter says. “We could identify who needs more screening or testing. We could do this in a preventative, forward thinking manner. That’s where my co-authors and I are excited. We feel like the potential payoff is so great, even if the current technology cannot meet these lofty goals.” Provided by Morgridge Institute for Research New technology makes artificial intelligence more private and portable Citation: Scholarly snowball: Deep learning paper generates big online collaboration (2018, April 4) retrieved 18 July 2019 from https://phys.org/news/2018-04-scholarly-snowball-deep-paper-big.html
