Is There HomeField Advantage At The Olympics

Soviet Union1980125195+70 MEDALS WON PER ATHELETE PARTICIPATING BY HOST COUNTRY Spain19920.020.05+0.03 We’re on the ground in Rio covering the 2016 Summer Olympics. Check out all our coverage here.Does Brazil have a home-field advantage in Rio?Again and again, research has shown that home-field advantage is a constant in sports across the world. Basketball referees call more fouls on the visitors. Pitchers for the home team in baseball get a wider strike zone. Home teams in soccer receive fewer yellow cards.To see whether the same is true in the Olympics,1In our recent article in the International Journal of the History of Sport. we analyzed medal counts since World War II2We excluded 1948 from the analysis because it had been 12 years since the previous Olympics. by comparing a country’s results in the year it hosted the games to its results in the games four years earlier. In other words, we estimated Great Britain’s 2012 home-field advantage by comparing its 2012 performance to its results from 2008. This is an improvement over previous research, which analyzed home advantage by comparing hosts to non-hosts in the same year, which ignores the fact that the average host (like Great Britain or China) is much different than the average non-host (like Djibouti or Paraguay). South Korea19880.110.08-0.03 Soviet Union19800.300.40+0.09 Why do host nations do so well? Research has pointed to referees or crowds as crucial to home advantage in other sports, but we found a unique factor driving the home advantage in the Olympics. The table above shows that the number of athletes that a country sends to the games jumps tremendously when it is the host. On average, there are 175.8 additional athletes representing the host country than represented it four years earlier.The main explanation for this increase is that qualification standards are lower for athletes from the host country. Olympic hosts are guaranteed a spot in each team sport. For example, the Brazilian men’s field hockey team will participate in its first Olympics in Rio de Janeiro. Host-country athletes who compete in individual events also have an easier time qualifying for the games. In the triathalon, for example, hosts are guaranteed at least one competitor of each gender. While some of these “add-on” host country athletes aren’t good enough to contend for medals, elite athletes from the host may participate in more events than they otherwise would.

The Brazilian team has 481 participants. That’s quite a jump from 2012 (248 participants) and 2008 (268). If Brazil’s medals-per-athlete rate were to stay about the same as in 2008 and 2012, it would be expected to win about 30 medals in Rio. And that would be the nation’s best Olympics showing ever (they won 17 in 2012).Brazil has the goal of a top-10 finish in the medals table. Italy, tenth in the total medal count in 2012, won 28 medals in London.6South Korea also earned 28 medals in London, although it finished in ninth place because it had more gold medals than Italy. Coming into Tuesday, the fourth day of the games, Brazil had one gold in judo and one silver in shooting.One gold medal that Brazil hopes to win is in men’s soccer, the country’s most popular sport. The men’s national team has won the World Cup five times but never Olympic gold. Beyond all the numbers, winning men’s soccer gold would make the games a success for many Brazilians.

On average, host nations of the Summer Olympics increase their overall medal count by 20.1 medals and their gold medal count by 10.9.5In our published paper, we use a slightly different statistical approach and find slightly smaller differences: +11.6 in total medals, +7.2 in golds. It is worth noting that the biggest jumps occurred for the Soviet Union in 1980, when the United States and allies boycotted the Moscow Games, and for the United States in 1984, when the Soviet Union and allies boycotted the Los Angeles Games — both times removing a major competitor in the medal count for the host nation. Excluding the years affected by these boycotts brings the average increase in overall medal count to 12.2 and in gold medal count to 6.8. United States1984396522+126 United States19840.240.33+0.10 Australia195681294+213 Greece2004140426+286 United States1996545647+102 To assess the impact that participation levels have on the medal count, we compared the ratio of medals to participants for host nations. The table above shows a much more mixed story about whether host country athletes are having more success at home. We find that, on average, Summer Olympics hosts win fewer medals per athlete, compared with their results just four years earlier (although this result is not statistically distinguishable from a difference of zero, which remains true even if we remove the games affected by the 1980s boycotts from the pool). This tells us that even though host countries tend to increase their aggregate medal count, the increase disappears when we account for the higher number of medal-winning opportunities. This is due in part to the host’s aforementioned automatic entry for team sports, which add a large number of athletes in one shot, and the fact that teams can win only one medal, while an individual athlete may enter multiple events.

Ohio State mens hockey jockeys for position as it heads into homeandhome

The Ohio State men’s hockey team is looking to take care of Robert Morris University in a two-game, home-and-home series before facing Miami next week in what could be a fight for first place in the Central Collegiate Hockey Association. This weekend, the Buckeyes, who are tied for second place in the conference with Notre Dame, will attempt to maintain their standing in the CCHA against the Colonials Friday night in Columbus before travelling to Pittsburgh for game two. In this series, OSU will try to keep pace with first place Miami, which leads the Buckeyes and Notre Dame by one point in the CCHA standings. Miami is home this weekend against eighth place Lake Superior State. If the Buckeyes and the Redhawks both win their respective series, their meetings on Dec. 14-15 in Columbus will be a head-to-head battle for first place in the CCHA. But OSU is trying not to look past Robert Morris. OSU coach Mark Osiecki said it’s a lesson the team learned last season. All the team is focused on now is a victory. “You want to go out there and win and it doesn’t matter who you’re playing,” Osiecki said. While OSU will look at Robert Morris’ tendencies as a team and prepare accordingly, it might ultimately come down to how well the Buckeyes execute their own game plan. “At the end of the day, all we are really focused on is us, and playing OSU hockey,” said sophomore forward Ryan Dzingel. The series is OSU’s only series this season where the two games will be held in different venues. When asked if this would affect the team, Osiecki said his players grew up playing in travelling junior leagues and had experience with the format. “They’re used to getting on a bus,” Osiecki said. “I don’t think it changes a thing, especially when you start at home.” Senior goalie Brady Hjelle echoed the sentiment about players having been in junior leagues. “It will be just like that, so it isn’t anything new to us,” Hjelle said. Hjelle was recently named CCHA goaltender of the week for the second consecutive week after holding Michigan State to one goal on 54 shots last weekend. It is Hjelle’s third goaltender of the week award this season. Both contests are set to begin at 7:05 p.m. read more

Opinion Peyton Mannings numbers dont make him the greatest quarterback in NFL

Denver Broncos quarterback Peyton Manning throws the ball during a game against the Arizona Cardinals on Oct. 5 in Denver. The Broncos defeated the Cardinals, 41-20.Credit: Courtesy of TNSWhen Peyton Manning broke the NFL’s all-time passing touchdown record last week with the 509th of his illustrious career, many wondered if the former Colt and current Bronco is now officially the greatest quarterback in the NFL’s history.He very well could be, but, in my opinion, breaking that record does not change a single thing.The man whose record Manning just topped? Brett Favre.Favre — even while he held the record — was rarely in the conversation surrounding who the best quarterback ever is.And the man Favre grabbed the record from back in 2007? Dan Marino. Marino, again, a great quarterback, but not easily classified as the greatest.The reason for those two not being the top quarterbacks of all time, even while each holding the career passing touchdowns and yardage records, is simple — championships.And it is the same reason why I believe Manning — for now, at least — stacks up a rung short of the top.Between Manning, Favre and Marino — the three greatest quarterbacks ever if you go by their individual passing yards and touchdowns — there are only two championship rings. Favre won one in a 20-year career, Manning has won one in a 17-year career and Marino never won a Super Bowl in 17 seasons.Manning is 11-12 in the playoffs. He has won 70 percent of his regular season games, but holds a losing record when it really counts.That is something that cannot be overlooked.Now, of course, wins and losses are team accomplishments and it is not fair to put it all on the quarterback. But Manning’s game has taken a step down in the postseason, beyond losing more games.In his career in the regular season, Manning has thrown 0.43 interceptions for every touchdown pass. Come playoff time, that number soars up to 0.65.In Super Bowls, Manning has thrown more picks than touchdowns. He averages more than two passing touchdowns per game in his career in the regular season, but has never thrown more than one in each of his three Super Bowl appearances.Heck, even in 2006 — the year Manning won his only ring — he threw seven interceptions compared to three touchdowns in the playoffs. That’s not simply just a step down for a great, that’s downright lousy.Karl Malone might have more points than Michael Jordan, but no one will ever mistake the Mailman for being in the discussion for the greatest basketball player ever.That is for the most part because Malone never won a championship, while Jordan elevated his already-phenomenal regular season play in the playoffs. By the end of Jordan’s career, he was six-for-six in the NBA Finals.Similarly, Joe Montana, a great regular season quarterback in his own right, stepped it up to another level when it really mattered. In four Super Bowl appearances, Montana never lost — and never threw an interception.Regular season statistics are great, but, at the end of the day, teams are after the pursuit of the gold. If Manning can add another championship before his career ends — which is rapidly approaching — the book can certainly be reopened.But for now, Manning’s accolades are not enough to lift him into the greatest ever until he can prove to have something different than the regular season wonders before him. read more

SubSaharan Africa SSA Say the words and most

first_imgSub-Saharan Africa (SSA). Say the words and most people think of poverty… famine… epidemics… political strife… sectarian violence. Yet, just recently, Microsoft announced a new investment on the continent, calling Africa a “game changer in the global economy.” So what gives? Game Changer? For starters, we concede SSA faces challenges… relatively low per capita GDP, relatively low life expectancy, and more than its fair share of military conflict. Nevertheless, considerable progress is being made. Politically, things have changed dramatically over the last two decades. In a recent report from financial advisory service firm KPMG titled “Africa Emergence—The Rise of the Phoenix,” researchers explained why… The end of the Cold War more than two decades ago brought new freedom to Africa. People started to demand political representation and called on governments to be more transparent. Democratic features were introduced and a vibrant civil society emerged. Influenced by this political renaissance, governments began to act more responsibly. Several ended hostilities with neighboring countries. With political change came economic change. Beginning in the 1990s, fledgling African democracies increasingly accommodated private enterprise by reducing trade barriers, cutting corporate taxes, and privatizing state-run industries. By the time the 2000s rolled around, these reforms started to gain traction. In 2000, GDP for all of SSA was a meager $331 billion. By 2012, it had quadrupled to $1.3 trillion. As far as the future is concerned, with more stable political and economic environments and the unleashing of market forces, SSA will reap the benefits of two megatrends: 1) growing demand for natural resources; and 2) increasing consumer spending by an expanding middle class. Let me explain… As the world’s population grows and per capita consumption rises in emerging economies, the demand for natural resources will increase… and SSA has plenty of natural resources, such as gold, oil, chromium, and platinum. But as important as natural resource exports will be, they aren’t the region’s only engine for economic growth. Consumerism is also a powerful factor, and it’s being driven by an emerging middle class. More and more SSA citizens are moving from subsistence farming to higher-paying urban jobs. In 2000, about 59 million African households were earning discretionary income; by 2020, discretionary income will be available to 128 million households. All of this points to the expectation of continued economic growth. Economists at the International Monetary Fund estimate that by 2018, GDP for SSA will reach $1.9 trillion. That amounts to a compounded annual growth rate of 7%, which compares favorably with estimates for Latin America and developing Asia of 4.7% and 8.1% respectively. Leapfrogging to the Tech Frontier Microsoft is not the only big tech company betting on growth opportunities in SSA. Intel, Google, Hewlett-Packard, and IBM have also invested heavily in the region. But are these companies a little early? Won’t the benefits to tech come after the buildup of roads, power grids, and healthcare systems? Not really. Whereas in developed countries, high tech has been “bolted on” to existing infrastructures years after they have been created, in developing regions, high tech can be integrated in as the infrastructure is constructed. For example, as the US struggles to mesh electronic health records with the healthcare system and smart-grid technology with the power grid, developing economies can build these features right into their nascent systems at the outset. In the words of John Kelly, head of research at IBM, Africa “can leapfrog straight to the tech frontier, without worrying about adapting old systems…” In addition, the Cloud is adaptable to and quite useful in the early stages of an economy’s development. According to The Economist, “The ability to use software, computing power, and storage online ‘as a service,’ paying only for what you need and only when you need it, may put the cost of information technology within the budget of many small African businesses.” The point is: the time for tech in SSA is now… not a decade from now. That’s why so many big tech firms are setting up shop in the region. Research firm IDC predicts that IT spending across Africa will increase from $30 billion in 2012 to $40 billion in 2016, and if telecom is included, spending will increase from $103 billion in 2012 to $130 billion by 2016. But here’s the thing: Africa won’t significantly move the revenue needle for the global tech giants, so investors should look elsewhere for opportunities. Our advice? An African telecom. The Gains Down in Africa As mentioned before, over the next few years, millions of SSA households will be acquiring discretionary income for the first time. That means millions more in the region will have more money to purchase necessities, and they’ll begin to purchase things like mobile phones and mobile services. According to GSMA, a global trade organization for mobile phone operators, there will be 250 million mobile phone connections in Africa over the next five years. That bodes well for African telecoms. But it’s a hotly contested space. So which telecom is the best bet? We like MTN Group Limited (MTNOY). The company is on solid financial ground. It pays a nice dividend. Its network is superior to the competition’s, which is why MTNOY is the market share leader in SSA. Oh, and the stock is cheap—even after the 12% run the stock has gone on since we recommended it in the December issue of BIG TECH. If you want access to our comprehensive report on MTNOY as well as access to our other buy recommendations, which include a networking equipment provider with 90% near-term upside potential, then sign up for a risk-free trial of BIG TECH.last_img read more

No other sector is as depressed as the mining sector. A return to anything close to some of the stronger past bull markets will hand us tremendous gains. The June issue of BIG GOLD focuses on the top silver pick listed in the table. I’m convinced it will at least triple from current levels in the next precious metals bull market. We have two very specific reasons why it will do so. And these two factors are unmatched by almost any other mid-tier or major producer. Get our analysis along with the name of this stock in the just-released BIG GOLD. We also include a special offer on bullion that has numismatic potential. These coins sell at bullion prices, yet will likely return much greater profit than standard bullion. And they come at discounted prices you won’t find elsewhere. It’s “The Two Best Silver Plays to Buy Today”—a highly actionable issue that tells you exactly what to buy and why. Get it now.

That’s because stocks will be rising from the depths of one of the more severe bear markets. Here’s what the price for popular royalty company Royal Gold would look like if it matched past bull markets.center_img We measured every bull cycle of gold stocks and found there have been eight distinct upcycles since 1975. We also discovered something exciting: Only one was less than a double. (A second was 99.9%.) Even more enticing is that the biggest one—a 601.5% advance in the early 2000s—occurred just after a prolonged bear market. And our current bear market is longer than that one. To get a sense for the potential upside, we applied the percentage gain from each of those upcycles to our recommended BIG GOLD picks. We can’t show you our entire portfolio out of fairness to paying subscribers. But look what those gains would mean to GDX, the Gold Miners ETF (based on the June 1 price). 554.2% 205.1% 141.8% 51.5% 99.9% 601.5% 206.4% 272.5% Keep two things in mind about this table: The percentage gain from each past bull market is calculated using an index. The stronger companies will perform better than a static ETF. Royalty Company Current Share Price 1976– 1980 1982– 1983 1986– 1987 1989– 1990 1993– 1994 2000– 2003 2005– 2008 2008– 2011 554.2% 205.1% 141.8% 51.5% 99.9% 601.5% 206.4% 272.5% You might think royalty stocks won’t show similar gains going forward. It’s true they’ve already performed well. However, it’s more likely they’ll be wildly popular than anything else. That’s partly because there are only a few of them in this industry. Now take a look at the prices our top silver pick would hit.last_img read more

Nanotechnology enables mice to see infrared light

first_imgIn our experiment, nanoparticles absorbed infrared light around 980 nm in wavelength and converted it into light peaked at 535 nm, which made the infrared light appear as the color green”.Jin Bao, University of Science and Technology of China In our study, we have shown that both rods and cones bind these nanoparticles and were activated by the near infrared light. So we believe this technology will also work in human eyes, not only for generating super vision but also for therapeutic solutions in human red color vision deficits.” The visible light that can be perceived by human’s natural vision occupies just a very small fraction of the electromagnetic spectrum. Electromagnetic waves longer or shorter than visible light carry lots of information.”Tian Xue, Senior Author, University of Science and Technology of China Source:http://www.cellpress.com/ Current infrared technology relies on detectors and cameras that are often limited by ambient daylight and need outside power sources. The researchers believe the bio-integrated nanoparticles are more desirable for potential infrared applications in civilian encryption, security, and military operations. “In the future, we think there may be room to improve the technology with a new version of organic-based nanoparticles, made of FDA-approved compounds, that appear to result in even brighter infrared vision,” says Han.The researchers also think more work can be done to fine tune the emission spectrum of the nanoparticles to suit human eyes, which utilize more cones than rods for their central vision compared to mouse eyes. “This is an exciting subject because the technology we made possible here could eventually enable human beings to see beyond our natural capabilities,” says Xue. When light enters the eye and hits the retina, the rods and cones–or photoreceptor cells–absorb the photons with visible light wavelengths and send corresponding electric signals to the brain. Because infrared wavelengths are too long to be absorbed by photoreceptors, we are not able to perceive them.”Gang Han, University of Massachusetts Medical School In this study, the scientists made nanoparticles that can anchor tightly to photoreceptor cells and act as tiny infrared light transducers. When infrared light hits the retina, the nanoparticles capture the longer infrared wavelengths and emit shorter wavelengths within the visible light range. The nearby rod or cone then absorbs the shorter wavelength and sends a normal signal to the brain, as if visible light had hit the retina. Related StoriesBlood based test using AI and nanotechnology devised for chronic fatigue syndromeNanotechnology treatment reverses multiple sclerosis symptoms in miceLight therapy may dramatically reduce neurodegeneration in Alzheimer’s diseaseThe researchers tested the nanoparticles in mice, which, like humans, cannot see infrared naturally. Mice that received the injections showed unconscious physical signs that they were detecting infrared light, such as their pupils constricting, while mice injected with only the buffer solution didn’t respond to infrared light.To test whether the mice could make sense of the infrared light, the researchers set up a series of maze tasks to show the mice could see infrared in daylight conditions, simultaneously with visible light.In rare cases, side effects from the injections such as cloudy corneas occurred but disappeared within less than a week. This may have been caused by the injection process alone because mice that only received injections of the buffer solution had a similar rate of these side effects. Other tests found no damage to the retina’s structure following the sub-retinal injections.Xue says: A multidisciplinary group of scientists led by Xue and Jin Bao at the University of Science and Technology of China as well as Gang Han at the University of Massachusetts Medical School, developed the nanotechnology to work with the eye’s existing structures. Mar 4 2019Mice with vision enhanced by nanotechnology were able to see infrared light as well as visible light, reports a study published February 28 in the journal Cell. A single injection of nanoparticles in the mice’s eyes bestowed infrared vision for up to 10 weeks with minimal side effects, allowing them to see infrared light even during the day and with enough specificity to distinguish between different shapes. These findings could lead to advancements in human infrared vision technologies, including potential applications in civilian encryption, security, and military operations. Humans and other mammals are limited to seeing a range of wavelengths of light called visible light, which includes the wavelengths of the rainbow. But infrared radiation, which has a longer wavelength, is all around us. People, animals and objects emit infrared light as they give off heat, and objects can also reflect infrared light.last_img read more

It’s a key component of day-to-day tasks like driving to a new location, making a recipe, or following instructions. Individuals with Alzheimer’s disease, which will more than double by 2050, and other forms of dementia, experience progressive loss of working memory and other forms of cognition, leading to a greater risk of injury or death and reducing their ability to function without home care.Twenty-nine young adults and 18 older adults completed the study, which involved trying to remember and then reproduce a series of letters in alphabetical order. The authors applied either online high-frequency (5Hz) rTMS, or a placebo-like sham over the left prefrontal cortex, an area on the brain responsible for higher executive function. Participants of all ages who received rTMS performed better than those who received the rTMS-like placebo. This study relies on highly individualized parameters, from the selection of the stimulated target, based on fMRI activation, to the selection of the difficulty, titrated according to subjects’ performance. Now that we have shown that these specific parameters can improve performance in healthy subjects, we will be able to extend it to populations with memory deficits.”Lysianne Beynel, PhD, postdoctoral associate in the Department of Psychiatry and Behavioral Sciences Interestingly, we only saw this effect during when participants were trying their hardest, suggesting a real use-it-or-lose it principle at work here. Contrary to much of what we hear, aging brains have a remarkable capability to remember past events and to use that information in a flexible manner. The brain stimulation applied in our study shows that older adults benefited just as much as the young.”Simon W. Davis, PhD, co-authorlast_img read more

Citation: Walmart US CEO talks technology, workers (2018, November 15) retrieved 17 July 2019 from https://phys.org/news/2018-11-walmart-ceo-technology-workers.html Q. So do you think you’ll drop the $35 minimum order for free shipping for the holidays?A. These things are always discussed and reviewed. Sometimes that means following and other times it doesn’t. Q. Does Amazon keep you up at night? A. To be frank, lots of things keep me up at night. Amazon is one of them. Target is another. I am in Aldi stores, Lidl stores. There’s no doubt that Amazon is a significant competitor. You keep tabs. But your job is not to copy.Q. How are you approaching wages given increasing competitive pressures?A. We look at it regularly. As you can imagine, it’s a particularly large country. We’ve made a lot of progress getting ourselves from where we were to $9, then $10, and then $11 earlier on this year. We’ve got a number of stores that pay well over that now, $12, $13, $14. So we continuously review that. We then take into account what we’re doing in things like benefits so parental leave, PTO (paid time off) etc. In this Friday, Nov. 9, 2018, photo Walmart U.S. President and CEO Greg Foran, center, high-fives an associate during a tour of a Walmart Supercenter in Houston.

That’s going to play itself out. I am a big proponent of the good jobs strategy. For a lot of tasks that you used to do that were mundane, tedious, we’re now working out how we can digitize those. And then we’re creating new roles through turning stores into fulfillment centers because now we’ve got thousands of personal shoppers who are picking your order, so the jobs are changing. Foran’s obsession with the nitty-gritty details has helped lead to several years of straight quarterly sales gains for the U.S. division. But with Walmart facing competition from Amazon and other pressures, he’s also reimagining the shopping experience at Walmart’s 4,700 stores, transforming them into distribution hubs that can fill the fast-growing online orders to reduce shipping costs and speed up deliveries. To do that, Walmart has been training its 1.5 million workers at its new academies while using automation to relieve them of menial tasks.Scanning robots at a store in Houston as well as a cluster of others keep tabs of what’s on and not on the shelves and communicate that information to the automatic conveyor system that’s backed up to the truck bay. Workers with new apps on their hand-held devices manage routine tasks like price changes on the spot, freeing them to serve shoppers and even check them out.Foran, who used to head Walmart’s China business, says he’s always looking to new technology that improves efficiency. Still he takes delight in old-school retail basics like watching shoppers open a carton of produce. AP recently spoke with Foran during a tour of the Houston store about the holiday season, his views on workers and other issues. The questions and answers have been edited for clarity and length.Q. What makes this holiday season different?A. I wake up on Monday morning at 4 a.m. and the first email I look at is Amazon has gone and introduced free shipping. You’re getting competitors out there starting to up the ante. I think we’ll see more business done online, not just at Amazon but at Walmart and in other retailers. I think the fact that people like Toys R Us are out of the market has changed the environment around toys, both physical and digital offering.
