Sheffield Wednesday boss Luhukay slates team’s defending after defeat at QPR

first_imgEmbed from Getty Images​Sheffield Wednesday manager Jos Luhukay admitted his side were punished for some sloppy defending in their defeat at QPR.Wednesday were beaten 3-0 at Loftus Road, where Nahki Wells, on as a substitute, fired home with seven minutes remaining after goals from Tomer Hemed and Luke Freeman.“In our defending we were not consistent enough and did not clear the dangerous moments. The goals were too easy,” Luhakay said.“We were not strong enough to win and the result of 3-0 says something about this game.“At 1-0 we had three or four moments when the ball was not lucky for our strikers to ​score​ and then QPR came one time in the second half and scored a second goal.“Our team did not give up. But the third goal we also gave away, losing the ball in a dangerous area.“When you do that you invite the opponent to score the third goal and then it’s over.“In possession we were poor. We could not keep the ball and every time the ball went to one of our strikers we were losing the ball.“The crucial moment was the second goal. Before that you must make it 1-1 and the game maybe goes in a different direction.”See also:McClaren hails Wells after QPR win again Follow West London Sport on TwitterFind us on Facebookby Taboolaby TaboolaSponsored LinksSponsored LinksPromoted LinksPromoted LinksRecommended for youApartments for Sale | Search AdsApartments in Dubai Might Be Cheaper Than You ThinkApartments for Sale | Search AdsUndoProperty Investment | Search AdsDubai Real Estate Investment Properties May Surprise YouProperty Investment | Search AdsUndoFood PreventAnti-Aging Foods That Will Make Your Skin GlowFood PreventUndoElcondicional.com找出為什麼你應該停止吃白麵包Elcondicional.comUndoU.S Green Card – Free check您是否符合入籍美國的資格?快速檢查一下。U.S Green Card – Free checkUndoHashtagchatterHuman Barbie Takes Off Makeup, Doctors Have No WordsHashtagchatterUndoHair Transplant | Search AdsThe Cost of Hair Transplant in Dubai Might Surprise YouHair Transplant | Search AdsUndoRelocation Target11 Most Luxurious Hotels That Will Surprise YouRelocation TargetUndolast_img read more

Talk the Walk

first_imgUpright walking—that distinctive human form of locomotion—is more complex than putting one foot in front of the other. Let’s talk the walk.Why do we walk the way we walk? “Walk this way” is more than a classic comedian gag (YouTube). John E. A. Bertram seeks to explain how special human locomotion is in a Dispatch in Current Biology. Here’s the summary of his report:The way we walk determines the energetic investment needed. Humans spontaneously alter their walking style to exploit energetic opportunities. New research demonstrates the sensitivity and timing of this optimization and opens the door to discovering the underlying mechanisms.Over a decade ago, we reported on Daniel Lieberman’s remarkable analysis of human endurance running, a unique human trait requiring multiple specializations to the body (11/18/04). But walking upright is no less complex. Scientists are only beginning to understand the processes involved:Locomotion is initiated by the motor control centers of the brain, and is subsequently influenced by various ascending and descending features of the neuromuscular and mechanical systems of the body. However, our bodies move in a manner that cannot neglect the influence of the physical environment. This is a complex issue, doubtless with a variety of key inputs. How does the brain choose the best strategy to drive the motion and placement of the limbs? Even for constant speed locomotion, such as walking or running on a treadmill, this question currently remains open. Although an interesting and fundamental basic question, finding the answer to this will have many practical implications. Understanding how the brain integrates its control program with changes in the function or circumstances in which the body operates will influence our ability to predict the outcomes of various interventions, whether surgical, rehabilitative or prosthetic. The ever-growing field of enhanced function and performance provided by artificial bio-integrated ‘exoskeleton’ devices will depend on understanding how the body will react to such influence.Indeed, trying to design robots and exoskeletons has underscored the complexity of human walking. Bertram describes challenges to designing artificial knee joints and other parts that can stay upright and move without falling over, let alone optimize their actions for best energy utilization. It’s a challenge to explain, in evolutionary terms, a human’s fast, responsive method of optimizing walking for best metabolic efficiency.We observe that healthy humans generally walk in a similar manner [as experimental subjects]. Is this because of species-level evolutionary adaptation, because our coordination systems develop and learn in the same way or because we are all solving basically the same energetic problem? Certainly all these factors (and more) have their influence. The Selinger et al. study conclusively demonstrates that humans do solve at least part of the problem by coordinating their movements to optimize immediate metabolic energy expenditure. At this point, the mechanisms through which this is accomplished are not clear, but it is impossible to identify mechanisms unless their effects are recognized. This study adds a new dimension (and a novel technique) to our understanding of how humans move the way they do in walking.The paper referred to by Selinger et al. in Current Biology is titled, “Humans Can Continuously Optimize Energetic Cost during Walking.” It reports on experiments where subjects were outfitted with robotic exoskeletons that altered their normal walking styles. The researchers found that “people readily adapted gait patterns to minimize energy use” and were able, within minutes, to converge on new energetic optima, even for small cost savings. After the next change, they could re-converge on the optimum within seconds. “Our collective findings indicate that energetic cost is not just an outcome of movement, but also plays a central role in continuously shaping it.” The body of their paper says almost nothing about evolution, other than noting that “Much theorizing has focused on optima being established over evolutionary timescales, through changes to body shape, muscle action, and the hardwiring of neural circuitry.” They were apparently more interested in the empirical, measurable results from experiments on real people.Restoring the ArtEvolutionary theorizing about the unobservable past seems far less valuable than helping people in the here and now. Live Science reports on exciting developments that are allowing a 26-year-old man, paralyzed for five years, to walk again under his mind’s control. Doctors channeled his brain waves to a computer that interpreted the signals, and sent them to devices on his leg muscles. The man trained his mind to control an avatar in the computer, learning how to control it in the same way required for moving his legs. After practice moving his legs while suspended above ground, he has just been able to walk 12 feet under his own power, with a walker and harness for safety.“Even after years of paralysis, the brain can still generate robust brain waves that can be harnessed to enable basic walking,” study co-author Dr. An Do, an assistant professor of neurology at the University of California, Irvine, said in a statement. “We showed that you can restore intuitive, brain-controlled walking after a complete spinal cord injury.“This is a quantum leap over previous methods like electrically controlled exoskeletons that allowed a veteran to walk again (Science Daily), and even a paraplegic to make the first kick of the 2014 World Cup (Live Science).Growing into the Optimal WalkKids can seem like clumsy walkers and runners, Medical Xpress notes. That’s because they are not just miniature adults. Their body proportions are different. Jim Usherwood of the Royal Veterinary College (UK) decided to look into the reasons for the childhood waddle, with fresh experience from his two young daughters. He put reflective dots on their limbs and recorded the energetic costs as they walked and ran.Building a model that represented the moving people as a single piston that was the length of the individual’s leg, Usherwood calculated the amount of muscle required to produce the power necessary to propel the individuals along at the speeds that he and Hubel had measured. The new model successfully reproduced the youngsters’ and adults’ movements.So kids move the way that they do simply because they are smaller than adults and their short limbs do not have enough time to produce the high powers needed to lift them into the air when running, not because they are training to be as good as adults.Who doesn’t treasure videos of their baby’s first steps? Humans are born to walk. Toddlers may start out a little awkward, but with a little growth and practice, they can take after Mom and Dad at full speed when told, “Walk this way.”Read this piece in Evolution News & Views about Optimization as an intelligent design science. When you see your own body performing high-quality optimization rapidly, you have to conclude that good design went into the hardware and software. The more detail we learn, the more difficult it is to believe that a supposed evolutionary transition from ape knuckle-dragging to upright walking and endurance running reduced to random mutations (Stuff Happens Law).We are glad to see progress in robotic exoskeletons that are starting to let paralyzed persons enjoy the freedom of walking again, and hope this wonderful technology will become rapidly available to those who have been confined to wheelchairs for years.  We who can walk, in the meantime, should value this ability while we have it.Because walking is usually associated with purposeful activity, it is a frequent metaphor in the Bible for lifestyle choices. “Be careful how you walk,” Paul says in Ephesians 5, “making the best use of the time, because the days are evil.” He also says in the same passage to “walk in love” and “walk as children of light.” Both in spiritual and physical senses, walking the talk and talking the walk require intelligent design.(Visited 15 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

SA phases in African language learning

first_img31 May 2013 The Cabinet this week welcomed the Department of Education’s move to start phasing in the learning of an African language at South Africa’s schools, saying it would go a long way towards promoting social cohesion and nation-building. The department recently announced it was preparing for the introduction of African languages as an additional language subject at all schools in 2014 by phasing it in in selected schools in each province this year. The implementation will require that all learners complete Grade 9 having learnt an African language for at least one phase. “All schools that do not have an African language as a language in their school language policy at all, will introduce incrementally from 2014 in Grade R and 1, the learning of an African language as another first additional language,” the department said in a statement. In schools where learners are already studying one African language and either English or Afrikaans, learners will learn another African language in Grade R and 1 in 2014. According to the department, the language selections made by school governing bodies often failed to promote the African languages of learners, forcing them to learn English and Afrikaans instead. “For our learners who do not speak an African language, many are still leaving the schooling system having never been taught an African language. “This must have huge implications for the constitutional and social goal of promoting social cohesion and nation-building in all our citizens.” Speaking at a post-Cabinet media briefing in Pretoria on Thursday, Public Service and Administration Minister Lindiwe Sisulu said the government encouraged all South Africans to learn an indigenous language, as this would promote multilingualism and foster nation-building.

Top 5 Spotify Apps For Music Discovery

first_img9 Books That Make Perfect Gifts for Industry Ex… 4 Keys to a Kid-Safe App john paul titlow Tags:#discovery#lastfm#music#Recommendation Engines#spotify Spotify wasn’t built for discovery. The Swedish music streaming company realizes this and instead of trying to natively bake a zillion features into its service, it launched a platform for third party developers about a year ago. Spotify’s app directory now features almost 60 HTML5-based add-ons for the service’s desktop client. These apps perform a lot of different functions – some are social, while others sonically augment album reviews from big name publishers. The thing for which they’re probably most useful is discovering music you might like but may never have heard otherwise.1. MoodagentSince launching on Spotify last year, Moodagent has been one of the most interesting apps on the platform. That’s because it takes standard algorithmic music recommendations and beefs them up with emotional intelligence. There are at least a dozen apps that let you build a playlist based on related artists, but Moodagent factors in the mood of each song to build out something that feels more consistent. The options look broad, but are surprisingly powerful. A playlist can be sensual, angry, happy, tender or some combination of all four. You can even base them on tempo, playing back a series of similarly paced songs. Tie these characteristics to the same kind of artist-to-artist matching algorithm that fuels so many other music-discovery apps, and you have a uniquely intelligent system for finding new music. 2. has been around for a decade now, but the Internet radio and music recommendation service is still a reliable tool for discovering new artists. It works by keeping track of everything you listen to and using a Pandora-style algorithm to recommend related artists and albums. It’s a simple concept, but one that apparently holds up quite well over time. Existing users of will feel right at home in its Spotify app, which more or less frames a slightly modified version of the service’s usual interface into Spotify’s desktop client. The results occasionally need to be tweaked, but on the whole the recommendations are pretty solid. A few albums in my own physical record collection landed there thanks to’s ability to turn up hidden gems.  3. Swarm.fmOh great, another social music-discovery app. Ho-hum.Actually, is pretty useful. It uses data from Facebook to show you what music your friends are listening to, even if they’re not signed up for If they are, that data becomes much more detailed and easily explored. will also let you know if any artists in your own collection have new releases, which is far more relevant than the new releases coughed up by Spotify itself. That tag cloud on the home tab might look like just another collection of metadata, but it’s actually informed by your social music data. I listen to a number of artists who don the tag “space rock” – and when I click that tag, it shows me dozens of similar bands. I can then sort those artists by popularity and what’s trending on, which is a good way to pinpoint worthwhile listens.4. ShareMyPlaylistsWhen I first opened ShareMyPlaylists, I thought “Oh, this is looks fairly generic.” Alternative, Classical, Blues, Dance. One-size-fits-all playlists.I was wrong. When you scroll down, you see a wide variety of very specific playlists: Beatles covers, the songs sampled by Nas and music from Quentin Tarantino films, songs featuring Moog synthesizers. It’s a random conglomeration of curated listening experiences, but one that is well worth browsing. ShareMyPlaylists has something for absolutely everyone. Devotees of popular music from the charts can browse the “Top 50” tab while those with more under-the-radar tastes will find plenty of new stuff under the “Recommended” tab, which finds playlists based on the artists you listen to the most. If nothing in either section suits your mood, you can always run a search or use the app’s built-in playlist generator. 5. The Hype MachineIt’s been a wildly popular MP3 aggregator on the Web for years, so it only makes sense that The Hype Machine would find its way into Spotify’s app store. It’s right at home on top of the streaming service’s massive library of music. The Hype Machine eschews the complex algorithm in favor of human-curated playlists. Specifically, it aggregates tracks from popular music blogs across a wide range of genres, each of them very heavily populated. Dream Pop, for example, isn’t exactly a top 40 genre of music, but the Hype Machine pulls together no fewer than 100 different blogs classified as such. It’s loaded with music, all hand-selected by Internet tastemakers and guaranteed to introduce you to something you haven’t heard before. A Growing Universe Of Music Discovery AppsNarrowing this list to just five selections wasn’t easy. There are plenty of discovery apps on Spotify worth checking out – top charts from We Are Hunted and Billboard and social music from TweetVine, Soundrop and Sifter. Depending on your tastes, the critic-curated recommendations from Pitchfork, Rolling Stone, NME or KCRW can be invaluable. It’s also worth mentioning that the new, supposedly Pandora-killing Spotify Radio feature is worth playing with. Its Echo Nest-powered recommendations are not quite as granular and effective as Pandora’s, but they’re quite good. Not only can you create a station based on any album or artist, but you can build one off of an entire playlist. This is pretty powerful. For instance, if you’ve starred a lot of music on Spotify, you can build a radio station based solely on those favorites. Here’s another Spotify Radio trick: The app will let you generate a Spotify a playlist based on your dozen or so most-played  albums of all time. You can then start a Spotify radio station based on that playlist, which is sure to contain a few tracks you’ll love, but have never heard before. And isn’t that the point of music discovery?center_img 5 Outdoor Activities for Beating Office Burnout 12 Unique Gifts for the Hard-to-Shop-for People… Related Posts last_img read more
