Caltech to Offer Online Courses Through edX

first_img To expand its involvement in online learning, the California Institute of Technology will offer courses through the online education platform edX beginning this October.The edX course platform is an online learning initiative launched in 2012 by founding partners Harvard University and the Massachusetts Institute of Technology (MIT). Caltech’s rigorous online course offerings will join those of 28 other prestigious colleges and universities in the edX platform’s “xConsortium.”This new partnership with edX comes one year after Caltech offered three courses through the online learning platform Coursera in fall 2012. The Institute will now offer courses through both platforms.“Coursera and edX have some foundational differences which are of interest to the faculty,” says Cassandra Horii, director of teaching and learning programs at Caltech. Both organizationsoffer their courses at no cost to participating students; edX, however, operates as a nonprofit and plans to partner with only a small number of institutions, whereas Coursera—a for-profit, self-described “social entrepreneurship company”—partners with many institutions and state university systems.The two platforms also emphasize different learning strategies, says Horii. “Coursera has a strong organizational principle built around lectures, so a lot of the interactivity is tied right into the video,” she says. Though edX still enables the use of video lectures, a student can customize when he or she would like to take quizzes and use learning resources. In addition, edX allows faculty to embed a variety of learning materials—like textbook chapters, discussions, diagrams, and tables—directly into the platform’s layout.In the future, data collected from both platforms could provide valuable information about how students best learn certain material, especially in the sciences. “Caltech occupies this advanced, really rigorous scientific education space, and in general our interest in these online courses is to maintain that rigor and quality,” Horii says. “So, with these learning data, we have some potential contributions to make to the general understanding of learning in this niche that we occupy.”Even before joining edX and Coursera, Caltech had already become an example in the growing trend of Massively Open Online Courses (MOOCs). Yaser Abu-Mostafa, professor of electrical engineering and computer science, developed his own MOOC on machine learning, called “Learning from Data,” and offered it on YouTube and iTunes U beginning in April 2012.Photos by CalTech and edXSince its debut, Abu-Mostafa’s MOOC has reached more than 200,000 participants, and it received mention in the NMC Horizon Report: 2013 Higher Education Edition—the latest edition of an annual report highlighting important trends in higher education. The course will be offered again in fall 2013, through both iTunes U and edX.Although Caltech is now actively exploring several outlets for online learning, the Institute’s commitment to educational outreach is not a recent phenomenon. In the early 1960s, Caltech physicist Richard Feynman reorganized the Institute’s introductory physics course, incorporating contemporary research topics and making the course more engaging for students. His lectures were recorded and eventually incorporated into a widely popular physics book, The Feynman Lectures on Physics, which has sold millions of copies in a dozen languages.Continuing in the tradition set by Feynman, the MOOCs at Caltech seek to provide a high-quality learning environment that is rigorous but accessible. “No dumbing down of courses for popular consumption . . . no talking over people’s heads either; at Caltech, we explain things well because we understand them well,” adds Abu-Mostafa.More information on Caltech’s online learning opportunities is available on the Online Education website.For more information, email Caltech’s Media Relations at [email protected] or visit EVENTS & ENTERTAINMENT | FOOD & DRINK | THE ARTS | REAL ESTATE | HOME & GARDEN | WELLNESS | SOCIAL SCENE | GETAWAYS | PARENTS & KIDS HerbeautyRemove Belly Fat Without Going Under The KnifeHerbeautyHerbeautyHerbeautyCouples Who Stuck With Each Other Despite The Cheating ScandalHerbeautyHerbeautyHerbeautyYou Can’t Wear Just Anything If You’re The President’s DaughterHerbeautyHerbeautyHerbeautyA Mental Health Chatbot Which Helps People With DepressionHerbeautyHerbeautyHerbeautyEverything You Need To Know About This Two-Hour ProcedureHerbeautyHerbeautyHerbeauty15 Countries Where Men Have Difficulties Finding A WifeHerbeautyHerbeauty Get our daily Pasadena newspaper in your email box.

Australia: Developers Scrap Plans for Coal-Export Expansion in Newcastle

first_img FacebookTwitterLinkedInEmailPrint分享Sydney Morning Herald:The $5 billion-plus Terminal 4 coal export expansion planned for Newcastle has been scrapped after demand for the fossil fuel failed to increase as expected.Port Waratah Coal Services said on Thursday that it would allow a lease for the terminal – known as T4 – to lapse, signalling that the project would not go ahead.Port Waratah’s two terminals, Carrington and Kooragang, last year exported 105 million tonnes of coal out of a combined capacity of 145 million tonnes, the company said in a statement.Newcastle Coal Infrastructure Group, operator of the city’s third terminal, shipped about 60 million tonnes, helping make Newcastle one of the largest coal export centres in the world.“With significant growth capacity available in the existing terminals, we do not expect that the conditions to support an investment of the large and long-term nature of Terminal 4 will be in place before the development approval lapses in September 2020,” Hennie du Plooy, chief executive of Port Waratah, said.The company is understood to have sunk many millions of dollars into T4, a project that secured its original lease in 2009. The first stage envisaged a 25 million tonne per year terminal, with plans to expand that in the future to 70 million tonnes.Jeremy Buckingham, Greens energy spokesman, said T4 becoming terminal was “wonderful news.”“Reality is catching up with the great lie that we can continue to export coal in an age of climate change,” Mr Buckingham said.The Greens called on the government “to develop a transition strategy away from coal” and the party would be making this a key election issue, he said.John Mackenzie, a Newcastle City Councillor, also welcomed the T4 decision.“From the outset the economics was against this, the science was against this and the community was against it but because of our broken planning system it was approved anyway,” Mr Mackenzie said.“Communities are sick of being placed in limbo by a planning system which has no red lights and a Government who won’t show leadership by refusing new fossil fuel projects at the outset.”More: Newcastle’s T4 coal port expansion scrapped as demand fails to rise Australia: Developers Scrap Plans for Coal-Export Expansion in Newcastlelast_img read more

Summertime in Frederick County

first_imgSummer is a beautiful time of year all over Frederick County, but it is truly stunning along its scenic byways. Whether you want to fill your weekend with unique stops and exciting attractions or you just want to spend an hour taking in the gorgeous views, a journey down one of Frederick County’s two most traveled roads is sure to be a memorable experience!Throughout the changing seasons, the Journey Through Hallowed Ground National Scenic Byway or Route 15 is full of engaging stops that will appeal to the whole family. One of America’s most unique and special destinations, Downtown Frederick boasts a charming Main Street filled with one of a kind restaurants, specialty shops, and a vibrant arts community. North of the bustling city lies the quieter countryside. Catoctin Mountain Park (NPS) holds 25 miles of hiking trails offering visitors a chance to get up close and personal with nature. Just on the edge of the park, Cunningham Falls State Park is home to a 78-foot cascading waterfall, lakefront beach, and loads of other recreational opportunities.Moving toward the Town of Thurmont, road trippers will find the Catoctin Wildlife Preserve and Zoo. This is one of the few places in the mid-Atlantic to board an open-air truck and ride right through the habitats of emu, zebra, and bison. If you would rather stroll at your own pace, the zoo offers walking paths surrounding over 450 exotic animals. Nearing the Pennsylvania border, travelers will see Mount Saint Mary’s University, home of the National Shrine Grotto of Lourdes, overlooking the path. Discover the story of Saint Elizabeth Anne Seton, the first U.S. born Saint, at the nearby Seton Shrine. Tour the museum, wander through the house where she lived, and step into the awe-inspiring basilica.If you are looking for an East to West (or West to East) adventure, look no further than the Historic National Road, America’s first highway. Dating back to 1811, what is today known as Route 40, was a crucial portion of the westward movement for many families. Today, travelers can explore along the Historic National Road in Downtown Frederick on Patrick Street. Consider a stop at the National Museum of Civil War Medicine which tells a story of healing and compassion and houses over 1200 artifacts in five expansive galleries.Further west, high atop South Mountain and hidden by the woods that surround it, sits the original Washington Monument. The beautifully manicured trail leading from the visitor center to the site is short, and not as rigorous compared to the two-mile march up the mountain that citizens took to create the attraction years ago. Like the monument in DC, visitors who reach the top of the monument are rewarded with an incredible view. Nearby South Mountain Creamery will satisfy even the strongest dessert craving with fresh from the farm ice cream! Tour the property to find out how the creamery’s dairy products are made on site.last_img read more

Social Control: Maduro’s CLAP

first_imgBy Diálogo January 24, 2020 In 2019, the food distributed through the Local Supply and Production Committees (CLAP, in Spanish) of the Nicolás Maduro regime, reached fewer families, while delivery time increased. In addition, some products, such as canned tuna and wheat flour, were excluded from the subsidized food program, said a report from Venezuelan nongovernmental organization (NGO) Ciudadanía en Acción (Citizens in Action) published at the end of 2019.According to the NGO, the delivery time for CLAP boxes (or bags) went from an average of 35 to 47 days in nine months. In February, the program delivered 11 million boxes, but in November this number dropped to only 2.5 million — data wasn’t available for December.“This year [2019], I’ve only received seven CLAP boxes as of mid-December,” said Pablo, a man in his fifties, who asked to remain anonymous, and who lives with his family in the town of Guatire, 25 miles west of Caracas. The boxes, he told Diálogo, last only five days for a family of five, and according to estimates by Ciudadanía en Acción, they cover only 15 percent of a person’s basic nutritional requirements.The program, created in June 2016, promised to deliver basic foodstuffs (corn flour, wheat flour, rice, pasta, sugar, canned tuna, oil, and powdered milk) every 15 days for only 10,000 bolivars ($0.30, according to the exchange rate for January 1, 2020). In the last two months of 2019, the bag cost 80,000 bolivars ($2.40), or more than half of the minimum monthly wage of 150,000 bolivar ($4.40), which the government approved in October.Another NGO, Transparencia Venezuela (Transparency Venezuela), received many complaints during 2019 about irregularities in the state program. The reports included delays in food delivery (of up to seven months in some scarcely populated areas), unsafe food (such as expired milk or food contaminated with worms), as well as boxes that were delivered opened or with missing products. In July 2019, the NGO also reported that many people had complained that they were not given the boxes because they had taken part in protests against the government.Government officials said that they would “optimize” the program, and attributed irregularities to boxes “going missing on their way” and theft from black market operators.For Edison Arciniegas, head of Ciudadanía en Acción, this is about the “politics of food.”“No social control mechanism is more effective than controlling water and food. If you control this, you control the population,” Arciniegas, who thinks the strategy has been effective so far, told Diálogo. “There are fewer protests, or at least they haven’t increased in certain areas, such as near Miraflores [the presidential palace], and they are less violent. Those who receive the CLAP benefits continue to be [members] of the opposition, but they refrain from taking a position that might endanger this supply.”last_img read more

Fantasy Injury Updates: Rex Burkhead, Devin Singletary, Rashaad Penny affecting Week 4 active/inactives

first_imgWEEK 4 NON-PPR RANKINGS:Quarterback | Running back | Wide receiver | Tight end | D/ST | KickerIs Rex Burkhead playing Week 4?UPDATE 2: Burkhead is officially ACTIVE.UPDATE: ESPN’s Adam Schefter reports Burkhead is expected to play in Week 4. (foot) practiced on a limited basis all week and is officially “questionable” Sunday’s game against Buffalo. It was unclear how snaps and touches were going to be divvied up in the Patriots backfield anyway, as James White is due to return this week. With Sony Michel struggling, it’s possible Burkhead plays a significant role again and has FLEX value, but between the uncertainty and the injury, he’s a risky start.WEEK 4 PPR RANKINGS: Running back | Wide receiver | Tight endDevin Singletary injury updateUPDATE 2: Singletary is officially OUT.UPDATE: Singletary is not expected to play in Week 4, according to NFL Network’s Ian Rapoport.Singletary (hamstring) got in limited practices on Thursday and Friday and is “questionable” for this week’s game against the Patriots.The big-play rookie always has boom-or-bust upside if he’s on the field, but with Frank Gore getting the majority of the carries and a brutal matchup on tap, Singletary should probably be on fantasy benches even if he’s active. Gore is a low-ceiling FLEX with Singletary out, and he loses even more upside if Singletary plays.WEEK 4 DFS LINEUPS:DK cash | DK GPP | FD cash | FD GPP | Y! cash | Y! GPPRashaad Penny injury newsUPDATE: Penny is officially OUT.After getting in limited practice sessions on Thursday and Friday, Penny (hamstring) has a “good chance to play” against the Cardinals this week, according to coach Pete Carroll.This doesn’t affect Penny owners as much as it does Chris Carson owners. The latter has been operating as Seattle’s lead back all season, but after losing fumbles in each of the first three games, his starting job is hanging by a thread. Penny had a big Week 2, so he could be in line for more touches this week, but given his injury, it’s impossible to know what to expect from this backfield against Arizona. Penny isn’t a bad FLEX flier, but there are obvious risks. If he’s out, Carson would remain a shaky RB2, and C.J. Prosise has some value as a potential PPR FLEX.MORE WEEK 4 DFS: Top values | Stacks | Lineup BuilderIs Melvin Gordon playing in Week 4?UPDATE 2: Gordon is officially OUT.ACTIVE Did you think you would care enough to look for injury updates on Rex Burkhead, Devin Singletary, and Rashaad Penny by Week 4? Fantasy football start ’em, sit ’em decisions are affected by starters and backups possibly being inactive, and this week, committees for the Patriots, Bills, and Seahawks are up in the air. Not only do the three aforementioned “questionable” RBs matter, but Justin Jackson already being ruled “out” means we might see the return of Melvin Gordon Sunday. It’s gonna be a weird week. Check back all day for updates to this article, or follow us on Twitter (@SN_Fantasy).

UPDATE: NFL Network’s Ian Rapoport reports Gordon will only play in an “emergency” today.USA Today’s Mike Jones reported Saturday that Gordon will be active and receive “limited” touches against the Dolphins on Sunday. Even limited snaps against the Dolphins can yield legit production, but Gordon is a major risk in all formats. Austin Ekeler should continue to receive the bulk of the RB touches and have RB1 value this week.last_img read more

Understanding Jumping by Leaps and Bounds: Geared Insect and Leaping Plant

first_imgTwo clever examples of leaping have been found in the living world, adding to the catalog of clever ways life gets around.Geared for action:  The media were all abuzz with pictures and stories of the “flightless planthopper,” a tiny insect with a big leap.  What’s new and fascinating is that it’s the first example known in the animal kingdom of functional intermeshing gears; the paper was published in Science Magazine.  The photos and videos on Nature, Live Science and New Scientist show gear cogs that intermesh like something you’d see in human machinery.  The electron-micrograph close ups are especially stunning.Surprisingly, only the young nymphs of the species have the gears.  In the final molts, the gears get stripped off, and the adults use friction to jump.  This does not mean the nymphs are better designed; adults can jump even better.  The authors of the paper said,Their improved performance may be due to other factors, rather than a consequence of abandoning the gear mechanism. An inherent limitation of gears is that if one tooth breaks, their synchronizing action is degraded. In nymphs, a breakage could be repaired at the next molt, but this is not possible after the final molt to adulthood. Alternatively, the larger size of adults may mean that friction between the trochantera is a more effective synchronization mechanism.New Scientist used the finding to comment on biological machinery in general:For a disconcerting experience, consider how mechanical you are. Humans may be conscious beings with higher feelings, but really we’re just fancy machines with joints, motors, valves, and a whole lot of plumbing.All animals are the same. Hundreds of gizmos have evolved in nature, many of which our engineers merely reinvented. Nature had rotating axles billions of years ago, in the shape of bacterial flagella. And weevil legs beat us to the screw-and-nut mechanism.The insect Issus coleoptratus is another animal with an unexpected bit of machinery hidden in its body. Its larvae are the first animals known to have interlocking gears, just like in the gearbox of a car.The gears apparently keep the legs in sync, allowing them to take off within 30 microseconds of each other.  “Infant plant hoppers, known as nymphs, can take off in just 2 milliseconds, reaching take-off speeds of almost 4 metres a second,” Nature wrote, posting a video of the action.  “For motions this rapid, some mechanical device is needed to keep the legs synchronized and to avoid lopsided jumps that might lead to the insects spinning out of control.”  See also Science Magazine ScienceShot.Leaping spores:  The spores of horsetail plants have another unusual mechanism for getting around.  Seen under a high-powered microscope, the spores have four “legs” that respond to humidity changes, curling and uncurling.  An intriguinig video clip on the BBC News shows how the spores not only use them to walk, but to leap into the air.A European biologist, fascinated with the Venus flytrap, was looking for other kinds of motion in plants when he found this.  Curling and uncurling like hair, the legs, or elaters as they are called, respond more rapidly because of a “special layered structure” in the legs.  As a result, the spores can leap into the air, to be carried aloft by winds.The discoverer is now using this clever idea to design self-propelled objects.  “These, they say, could be used in agricultural settings, for example, using changes in humidity to power environmental monitoring probes or seed-dispersing devices.”  The director of the Royal Botanical Gardens commented, “we have so much more to learn from nature.”These two examples show the two sides of biomimetics.  The horsetail spores inspired a scientist to recreate the technology for human applications.  In the planthopper gear example, what we thought was a human invention turns out to have been scooped by an insect.  Nature had it first.As usual, the evolution-talk was superfluous and illogical.  New Scientist repeated the “nothing but” idea: humans and animals are nothing but machinery.  That’s self-refuting, because a scientist arguing the truth of a proposition is using abstract, non-physical thought, assuming truth exists outside of material nature.  Also, saying  “Such-and-such evolved to” is a logical fallacy in Darwinism.  Nothing evolves “to” do something.  In Darwinism, stuff happens, accidental mutation by accidental mutation.  Unguided processes cannot work toward a goal.  Adding millions of years doesn’t change that.On the contrary: whenever we see functional design, we naturally infer that intelligence played a role in its origin.  Darwinism only provides after-the-fact just-so stories to try to rationalize a secular world view.  Who needs that?  Think design, and you make progress in science.

Underwater Marvels

first_imgCheck out these amazing creatures that inhabit the liquid universe of planet Earth’s oceans and rivers. Only the first one is a fish.Aquatic hunger games: Archerfish spit the distance for food (Science Daily): “Described as nature’s sharpshooters or water pistols, archerfish inhabit the mangroves of southeast Asia and northern Australia.” Experiments show they can shoot distant targets, but prefer the closer ones.Marine animal colony is a multi-jet swimming machine, scientists report (PhysOrg): Tiny jellyfish that hang together are inspiring multi-engine underwater propulsion systems. The jellyfish, called siphonophores, use a propulsion mechanism that is “relatively rare in the animal kingdom”—squirting from multiple identical orifices. It allows them to “turn on a dime, very rapidly.” Science Daily adds, “This is a highly efficient system in which no developmental stage is wasted…It’s a quite sophisticated design, for what would seem like a simple arrangement.”Giant sea scorpion found in Iowa (Science Magazine): Fragmented fossils of a human-size sea scorpion were dug up in northeastern Iowa, presenting a conundrum for evolution: “Either eurypterids diversified quickly during the early stages of the Ordovician period (which began about 485 million years ago), or their lineage, including yet-to-be-discovered ancestors and kin, evolved more slowly and originated even further back in time during the Cambrian period—possibly during the Cambrian explosion, a period of evolutionary diversification sometimes called ‘life’s big bang,’ which began about 542 million years ago.” Euryptids are arthropods like trilobites.First cephalopod genome contains unique genes involved in nervous system, camouflage (PhysOrg): The genome of a California octopus surprised scientists with its complexity, comparable to the human genome. A one-minute video clip in the article shows the octopus undergoing rapid color changes to match its surroundings, even creating half-and-half patterns.  See also Evolution News & Views on the findings; also here.Rare nautilus sighted for the first time in three decades (Science Daily): The beautiful chambered nautilus (another cephalopod) once graced the seas in large numbers and huge sizes. Now, they are rare. Peter Ward (U of Washington, co-author of Rare Earth) was glad to find a couple of them in the South Pacific after 3 decades without any sightings. “This could be the rarest animal in the world,” he commented.Do whales get the bends? (National Geographic): There’s no reason they wouldn’t, except that they have specialized fat that can absorb the nitrogen bubbles that naturally form when a mammal rises to the surface too quickly. “Researchers from the University of North Carolina Wilmington investigated how marine mammals’ tissues—specifically, fat deposits in the jaws of toothed whales that are used in echolocation—absorb nitrogen gas, one of the gases that contributes to the bends. They found that the makeup of the fat affected how much nitrogen gas dissolves in it—and that different species had different fat compositions.”If you haven’t yet seen Living Waters: Intelligent Design in the Oceans of the Earth, by all means obtain a copy. It’s available on DVD (click the link) and will be coming out in Blu-ray this month. This film delights the viewer with great stories and facts about sea creatures while simultaneously demolishing Darwinian explanations. Filmed in Bermuda, Honduras, Canada, California and other locations, it is loaded with spectacular imagery (including great overhead drone shots), beautiful music and cutting-edge science.
