Crystal Palace manager Frank de Boer gestures on the touchline during the English Premier League soccer match against Burnley at Turf Moor, Burnley, England, Sunday Sept. 10, 2017. (Martin Rickett/PA via AP)The impatience and short-term thinking in modern-day soccer was highlighted Monday when Frank de Boer was fired by Crystal Palace only four Premier League games into his task of changing the ingrained playing style of the English team.Hours after Palace chairman Steve Parish called for “some sense” regarding the speculation surrounding De Boer’s position, the club’s board decided to end the Dutchman’s 77-day stint in charge and thanked him for his “dedication and hard work.”ADVERTISEMENT LATEST STORIES Facing yet another fight to avoid relegation from the world’s richest league, Palace seems destined to lurch back to survival mode. That likely means regressing to the style of play that Allardyce and Pulis developed, namely being more obdurate at the back and hitting teams on the break.The well-travelled Hodgson does not have a definitive preferred playing style, although his time with England from 2012-16 was marred by dull and cautious performances at major tournaments. He hasn’t coached since leaving the England job after the country’s elimination by Iceland at last year’s European Championship, and his last job as a club manager was at West Bromwich Albion from 2011-12.Arriving on a three-year deal , De Boer had ambitions of making Palace entertaining to watch and integrating more youth-team players. Parish and the club’s American owners — David Blitzer and Josh Harris — backed this bold vision.They have acted decisively, though maybe prematurely, in removing De Boer.Sports Related Videospowered by AdSparcRead Next Palace has lost all four of its league matches under De Boer, without even scoring a goal. The last team to make such a start in England’s top flight was Preston in 1924.Still, it was undeniable that De Boer needed time to implement a more expansive and entertaining style of play requested by the club’s hierarchy, which is a giant leap from the pragmatism, directness and counter-attacking favored by two of Palace’s three most recent managers — Sam Allardyce and Tony Pulis.FEATURED STORIESSPORTSRedemption is sweet for Ginebra, Scottie ThompsonSPORTSMayweather beats Pacquiao, Canelo for ‘Fighter of the Decade’SPORTSFederer blasts lack of communication on Australian Open smogIn terms of games played, De Boer’s tenure is the shortest of any permanent manager in Premier League history.Palace lost to Huddersfield, Liverpool and Swansea before the international break, and then 1-0 to Burnley on Sunday despite an improved display at Turf Moor which showed that De Boer’s methods might be starting to take effect. Surprising start to season: Madrid struggles, Barcelona thrives Mayweather beats Pacquiao, Canelo for ‘Fighter of the Decade’ Learning about the ‘Ring of Fire’ A costly, catty dispute finally settled Break new ground MOST READ It’s too early to present Duterte’s ‘legacy’ – Lacson De Boer spoke after the game of having “hope for the future,” but he won’t be part of it. British media reported that former England coach Roy Hodgson, who is 70, was in line to take over at a club where he was a youth-team player in the 1960s.While De Boer was gaining plenty of sympathy for his plight, critics of the decision to fire him placed the blame on those who hired him in the first place. Why ask a manager to implement a new playing approach and not give him a decent opportunity to see the change through, especially after only one transfer window when De Boer was unable to bring in the kind of attacking players to suit the new style?“You try to ask a bit of time for your work,” Chelsea manager Antonio Conte said Monday, when asked about Palace’s decision. “To finish this experience after only four games, I’m sorry for him.”De Boer was in charge of Inter Milan in his previous job for just 84 days before being fired early last season. He didn’t even last that long in his first foray into English soccer.As a former player and coach at Ajax and also a former Barcelona player, De Boer is wedded to a philosophy of possession and fluidity generally favored by the Dutch. It got results at Ajax — he won four straight league titles — but he has found it difficult to transfer that abroad.ADVERTISEMENT View comments Don’t miss out on the latest news and information.

Often the most interesting science stories are the ones about us– how our bodies and minds function. Actions we perform each day without much thought are made possible by precision engineering, sometimes at the molecular level. Here is a selection of news briefs about human superpowers.Electrical engineering: We have untold myriads of electrical voltage sensors in our cells. They are so small, scientists must use extremely delicate techniques of X-ray crystallography to try to determine their structure. Science Now summarizes recent papers by Roderick MacKinnon et al. (see 05/01/2003, 3/12/2002 entries) about potassium channels in the membranes of neurons. The structure of the pores and the adjacent voltage sensors is coming into focus. There are four positively-charged arginine molecules (amino acids) that sit on top of the voltage sensors that surround the channel. “These charged arginines,” the article says, “move in response to changes in the voltage across the cell membrane, pressing up and down on the lever that opens and closes the pore.” Just how this movement takes place is still unknown, but it happens really fast. That’s what makes you cry ouch almost instantly after stubbing your toe: an electrical current, set up by these voltage-dependent ion channels, travelled from neuron to neuron from toe to brain in a fraction of a second.Optical engineering: What could be clearer than a cornea? This outer surface of the eye looks simple, like a glass lens, but it is very complex. EurekAlert summarized work by the American Society for Biochemistry and Molecular Biology. The scientists identified 141 distinct proteins in the cornea, 70% of which were previously unknown. (For the structure of protein, see our online book). These complex molecules perform many important roles, such as “antimicrobial defense, heme and iron transport, tissue protection against UV-radiation and oxidative stress,” it lists. “Several other proteins were known antiangiogenic factors, which prevent the formation of blood vessels.” The cornea is not a mere gateway for light, but a lively, active place, constantly undergoing maintenance, repair and cleaning. The September issue of Sky and Telescope recommends that you think carefully before deciding on laser surgery on this delicate, dynamic, living surface.Software engineering: Perceiving perception: Your brain uses database technology. A press release from Howard Hughes Medical Institute states that “The brain may interpret the information it receives from sensory neurons using a code more complicated than scientists previously thought.” This “perception code,” studied by experiments with monkeys (which presumably have similar neuronal equipment to humans) found that “most attention to the first 250 milliseconds of neural firing, and that their attention falls off exponentially from there.” Maybe some form of attention deficit is built in to deal with TMUI (too much uninteresting information). See also a related report on EurekAlert about work at Johns Hopkins, “How the brain understands pictures.” Researchers found that “the system continuously organizes the whole scene, even though we usually are attending only to a small part of it.” Three or four times per second, the brain organizes the chunks of a scene into something like a database, according to a “sophisticated program” to “select and process the information that is relevant at a given moment.” As one researcher visualized it, imagine the challenge of pulling order out of a chaotic jumble of Lego blocks. He said, “the visual system first has to arrange this bag of blocks into useful ‘chunks’ and provide threads by which one or the other chunk can be pulled out for further processing.”The Cellular 007: When major threats arise, sometimes you have to give the cops their leash and turn them loose to do whatever is necessary to maintain security. EurekAlert reported on work by Yokoyama et al. at Washington School of Medicine. They found that natural killer cells act like the “James Bond” of the immune system. Under certain circumstances, the body gives them a “license to kill” – “the arsenals of natural killer cells only become fully armed after a receptor on their surfaces interacts with a molecule on the surfaces of other cells.” That’s the warrant to search and destroy. The article says that these natural killer cells are produced in the bone marrow, and that the entire population is replaced in a week’s time. “The molecular details of the process were so unusual,” says the report, “that Yokoyama and his colleagues found themselves struggling to develop terms to describe it to other immunologists.”Safe Stem Cells: Scientists at Pittsburgh School of Medicine, reports EurekAlert, have found that discarded placentas apparently contain stem cells with the “same potential as the more controversial counterparts,” embryonic stem cells. If so, then “placentas would no longer be relegated to the trashcan,” but become a lifesaving source of regenerative material. See also the MSNBC News report.Navigational Guidance and Control: Those orthogonal semicircular canals in our inner ears do more than just help balance. Because they respond to acceleration and deceleration, reports EurekAlert on work by the Institute of Neurology in London, they provide the brain with inputs for an “on-line movement guidance system” that is crucial when visual cues are absent, such as finding your way in a dark room. Additionally, the otolith organs (see 10/10/2003 entry), part of the vestibular system, are essential for determining which way is up. The article states that “the inner-ear vestibular organs provide what is essentially an on-line movement guidance system for maintaining the accuracy of whole-body movements.” This not only helps those of us lost in the dark, but highly-trained specialists undergoing “complex, high-precision whole-body movements, such as those of the gymnast or circus performer.” Visualize an acrobat balancing and catching a jug on his head and making it spin around, or picture an Olympic gymnast on uneven bars nailing a double twisting dismount, or a skater executing a perfect triple Lutz. You can bet those vestibular organs are working overtime. The full article by Brian L. Day and Richard C. Fitzpatrick, loaded with praise for the vestibular system, can be found on Current Biology, Volume 15, Issue 15, 9 August 2005, pages R583-R586. Here is the opening paragraph:Small, beautifully formed and locked in the skull, the vestibular organs continuously bombard the brain with messages. The messages are quite unlike any others. They tell of accelerations, how the head is rotating and translating and its orientation in space. The messages never stop and cannot be turned off. Even when we are completely motionless, they signal the relentless pull of gravity. Perhaps because of their constant monologue, the vestibular sensation is different to the other senses. There is no overt, readily recognizable, localisable, conscious sensation from these organs. They provide a silent sense. A body is a terrible thing to waste (speaking of waist, there can be too much of a good thing). Whether your body is fully functional or afflicted with a malady or two, you have a marvelous set of capabilities, and a dignity underscored by the complexity of the engineering that went into your making. Even if you are completely disabled, there is more complex engineering working properly under the skin than you could possibly realize. Fill in the box you were given. Exercise, eat right, practice. Maintain your machinery in optimum working order. Aim your body at something noble and worthwhile. You have a huge support infrastructure, with a staff of trillions behind the scenes, hoping you will make the right choices.(Visited 10 times, 1 visits today)FacebookTwitterPinterestSave分享0
27 October 2010 South Africa is to embark on a new economic growth path in a bid to create five-million jobs and reduce unemployment from 25% to 15% over the next 10 years. The announcement was made on Tuesday by Minister in the Presidency for Performance Monitoring and Evaluation, Collins Chabane. Chabane was speaking to journalists in Pretoria following a special Cabinet meeting called by President Jacob Zuma on Monday, and ahead of Finance Minister Pravin Gordhan’s medium-term budget speech in Parliament on Wednesday.Job creation at the centre of economic policy Chabane said the new growth path aimed to address unemployment, inequality and poverty by unlocking employment opportunities in South Africa’s private sector. “The new growth path is a broad framework that sets out a vision and identifies key areas where jobs can be created. The growth path we are announcing today places employment at the centre of economic policy.” Critical to the plan, he said, would be the partnering between key social players, business and government to address structural challenges in the economy.Regulatory reforms The government had realised that the economic growth and commodity price boom experienced over the past years had not seen revenue being sufficiently applied to promote economic spread and skills development in the country, Chabane said. The government also agreed that while South Africa’s economy was among the first to show signs of recovery following the global recession, regulatory reforms that encouraged employment and fought poverty were needed. The recession, which claimed more than a million jobs in 2009, took a heavy toll on South Africa’s economy, with households suffering from falling incomes and high levels of debt. The domestic economy further contracted by an estimated 1.8 percent as a result of a decline in consumption spending and weak investment growth. Chabane said the new growth path would exploit some of the opportunities that arose from the recession.Building an integrated African economy He cited China, India and Brazil as examples of countries with growth prospects similar to those of South Africa. The country could use its influence and experience to gain similar ground on the continent. “The new growth path commits South Africa to work with other countries on the continent to build a single African integrated economy, embracing one billion consumers, and to focus immediately on expanding economic links with the rest of the continent.” At least six key sectors, including infrastructure development, agriculture, mining, the “green” economy, manufacturing and tourism, had been identified as having potential to unlock employment opportunities. Partnerships Chabane and Economic Development Minister Ibrahim Patel agreed that it would probably take more than the government and the business sector for the country to achieve the new growth plan. Patel’s department is behind the Industrial Action Plan, which initially paved a way for the country’s new growth path. “Implementation and setting clear targets will remain a critical part of our work, and that is why we will be engaging all partners from all walks of life, and Cabinet will play a big role in coordinating all stakeholder commitments in this regard,” Patel said. The Cabinet Economic Team is headed by Rural Development Minister Gugile Nkwinti, who is also at the centre of speeding up economic growth in the country’s remote parts through various land reform policies. Nkwinti said that, through agricultural and land reform programmes, several employment opportunities that supported the new growth part were already in the pipeline. These included a special fund that had been created to assist emerging farmers in at least five of the country’s provinces. “Our area of focus will be on identifying skills, with the hope of using the funding to create more self-reliant businesses through partnerships of small and big commercial farmers,” Nkwinti said.

Display connections are evolving to keep up with new video technology and data rates. See what lies ahead for the future.Chances are, you have a shoebox filled with a bunch of obsolete connectors collecting dust in your garage, or worse, your parents’ house. Each of these cables and display connectors can only fulfill one specific connection. You can’t mix a VGA cable with a tri-colored composite cord and expect it to work; the connections look and act differently from each other. This was the norm for years.Today, the trend is moving toward fewer display connectors that handle more. This will be great news for your parents, who will bug you a little less about clearing out those ratty shoeboxes. They’ll still bug you, just about other stuff.Connectors now are able to handle multiple signal formats, so they can carry video, audio, and data information while often being able to charge the connected device. This’ll be familiar to anyone who’s got a smartphone, and in fact, this connectivity trend is being driven by consumer devices like advanced phones and tablets. Compare this to a decade ago, where connections were driven by advances and needs of professional equipment.The interfaces through which we connect our devices are getting smaller, denser, and faster, much like the phones themselves, now sporting fewer ports. The interfaces can make decisions about display resolutions, audio formats, Ethernet connectivity, and can receive and send control signals, so you don’t have to sweat the details. All of these interfaces use Extended Display Identification Data which allows your video card to configure itself automatically. This is what makes your display rotate to landscape mode when you plug in your phone to display content on a TV. What’s more, wireless connections are also right around the corner.Image: Apple Thunderbolt ConnectorsThunderbolt is a great example of this technology, as is Mobile High-Definition Link (MHL) and DockPort, a USB connection over DisplayPort. MHL, a smaller version of HDMI carrying signal over Micro USB, can be used for a wide variety of applications, including using the phone as a game controller to replace standard hand-held ones. MHL can also be used in a phone-docking scenario to operate as a full-fledged computer. Other models that turn phones into tablets exist as well.Certain types of DisplayPort utilizing USB 3.0 have built-in chips that enable the interface to configure automatically to the connected system. The cables are also symmetrical so it doesn’t matter which way you plug it in. You’ve seen this on more modern iPhone chargers and Apple’s display connector.A Look Into The FutureAll this shouldn’t come as a shock to anyone who owns one or more of these devices. The problem is the looming inevitability of 4k and later, 8k footage, which will put an intense strain on these interfaces.4k video will become standard on the next generations of smart phones, so this issue is about to come to a head. Models released by LG, Sony and Samsung will all utilize playback through MHL and will come equipped with 13 megapixel cameras. It’s not just about servicing a greater array of pixels, though. Any developments in refresh rates, dynamic range, and color gamut will affect how much information needs to be pushed through these multi-purpose connectors.Let’s take a look at the two most common connectors, HDMI and DisplayPort, to see how they fare. HDMI can carry 4k video at 60p but is limited to 8-bit color only, according to the HDMI 1.4 and 2.0 specs. At higher formats, we’ll encounter speed problems in the actual connector portion of the signal chain.DisplayPort 1.2 is robust enough to handle 10-bit color with a 4k signal at 60p, running at a data rate of 21.6 Gb/s. DisplayPort 1.3, announced in September this year, will carry a maximum data rate of 32.4 Gb/s, utilizing the device’s four separate lanes running at 8.1 Gb/s each. It’s almost twice as fast as HDMI.Image: Displayport CableHelping DisplayPort achieve this is something called Display Stream Compression. As the name suggests, the technology condenses information packets coming to the monitor from the video card. The standard would support an 8k stream, although at a lower color space of 4:2:0. Once the video signal itself is taken care of, there would still be a fair amount of room to pass other devices such as Thunderbolt, USB and Ethernet connectivity through the connection.This gives us some ammunition when confronted with claims that a manufacturer’s products are “UltraHD ready.” Be sure to ask which interface is making the connection happen, as there are large differences between the current states of HDMI and DisplayPort technology. Many TVs contain HDMI but they may be an older specification that cannot carry as robust a signal.High dynamic range is something we’ll be looking for aside from just having large image support. As more entertainment gets streamed from what are essentially computers tuned to RGB color spaces, the throughput to display these images also demands more. It’s increasingly important to develop the specs properly to accommodate the highest quality possible.
PANAJI: The top bureaucracy in Goa, led by the Chief Secretary, was grappling on Friday evening with the finalisation of notices to outlets serving liquor within 500 metres of highways.On December 15, the Supreme Court had banned sale of liquor within 500 metres of highways across the country. On Friday, the apex court said the ban is not limited to retail liquor outlets, and includes bars, pubs and restaurants.The State Finance Secretary, Daulat Hawaldar, told The Hindu that though the government was yet to receive a copy of the SC’s review order, which had given some State-specific relief based on pleas filed by some States, it was clear that no relief has been provided to Goa.The State government was gearing to issue notices to 3, 200 outlets, including retail outlets, shops, restaurants and even wholesale liquor shops, identified by a special committee headed by State Excise Commissioner Menino D’Souza.Earlier in the week, the government had decided to issue notices to only around 789 retailers.
