GRANTS FOR WOMEN IN SPORTS LEADERSHIP

first_imgThe Australian Sports Commission (ASC) and the Australian Government Office for Women have distributed the following information regarding the 2005 Sport Leadership Grants for Women. The program is aimed at providing women with an opportunity to undertake certified sport leadership training. This program builds on the grants program offered in 2004, opening the grants out to all areas of Australia, with an additional category for women in high performance coaching and officiating. However, the grants will maintain a selection priority to women in rural and remote communities. The program offers grants in five key areas: * High Performance coaching and officiating; * Indigenous women in rural and remote communities; * Women in disability sport; * Women from culturally and linguistically diverse backgrounds; * Women in general sports leadership, eg: coaching, officiating, club development and management, board and committee skills and sports medicine. The Program provides successful applicants with a one-off grant of up to $5,000 for individuals (applications must be through an incorporated organisation) and up to $10,000 for incorporated organisations. The types of projects eligible for funding include: * Industry qualifications/ statement of attainment as part of a nationally accredited course, eg: accreditation through the National Coaching or Officiating Accreditation Scheme * Conducting and attending sport specific leadership courses Applications for the grants close on Friday 28 January 2005. The ASC’s information booklet and application form are available to be downloaded here: WOMEN IN SPORT LEADERSHIP- GRANTS INFORMATION/APPLICATION FORM If you require any further information about the grants please call (02) 6214 1103 or email: leadershipgrants@ausport.gov.au.last_img read more

OPEC countries to pump more oil to contain price increase

first_imgWhile OPEC’s largest producer, Saudi Arabia, is seen to be open to higher production, Iran has been hesitant because of its trouble to increase output and tensions with the U.S. President Donald Trump has been calling publicly for the cartel to help lower prices.The production limits by the Organization of the Petroleum Exporting Countries and Russia since 2016 have helped increase oil prices, with the benchmark U.S. crude contract hitting its highest level in more than three years in May. Some analysts note that while Trump has blamed OPEC, his policies have also helped increase the cost of oil by, for example, limiting exports from Iran.Some analysts believe that Saudi Arabia needs a Brent price closer to $90 a barrel to cover its domestic spending but is feeling pressure from the United States to head off rising prices by boosting output. Russia may be happy to pump more oil and settle for prices in the $60s, according to Tamar Essner, chief energy analyst for Nasdaq.There are other considerations than dollars and rubles. How that translates into effective production increases is uncertain, as some OPEC countries cannot easily ramp up production. Iran, for example, has been hit by U.S. sanctions that hinder its energy exports. Venezuela’s production has dropped amid domestic political instability.The price of oil jumped after the announcement, with the international benchmark, Brent, gaining $1.61 to $74.66 a barrel.Al-Mazrouei noted that the decision “is challenging for those countries that are struggling with keeping their level of production.” However, he indicated that some countries could pick up production if others lag.“We will deal with it collectively,” he said.Friday’s decision means OPEC will observe the production level it agreed on in late 2016, when it cut output by 1.2 million barrels a day. In practice, its combined output was even less due to production problems. That has since then helped push up the price of oil by almost 50 percent.Non-OPEC countries like Russia had agreed in 2016 to participate in OPEC’s effort to raise prices, cutting 600,000 barrels a day of their own production. They will discuss with OPEC on Saturday on whether to increase their own production. Daniel Yergin, the vice chairman of research firm IHS Markit and author of several books on the energy industry, says geopolitical factors are a big element in the oil production talks.Yergin said Saudi Arabia and the United Arab Emirates support the current, tougher U.S. policy toward Iran, Saudi Arabia’s rival for influence in the region. So they will want to support Trump’s call for higher production and lower prices. Iran will struggle to increase production, meaning it could lose market share and revenue.By Kiyoko Metzler And Geir MoulsonTHE ASSOCIATED PRESScenter_img VIENNA, AUSTRIA – The OPEC oil countries agreed Friday to increase their combined production by almost 1 million barrels a day, though questions remain over some members’ ability to do so amid domestic trouble and sanctions.After a meeting in Vienna, Emirati Energy Minister Suhail al-Mazrouei said the cartel decided to fully comply with its existing production ceiling.Because the group had been producing below that level, that effectively means an increase in production. The minister said that amounts to “a little bit less than 1 million barrels.”last_img read more

Baseballs Savviest And Crappiest Bullpen Managers
Baseballs Savviest And Crappiest Bullpen Managers

At a glance, this leaderboard passes the sniff test. Aside from interlopers such as erstwhile Braves skipper Fredi Gonzalez and former A’s manager Bob Geren, it’s a list of eight well-respected tacticians. Moreover, the first five men listed have all won Manager of the Year awards, as have seven of the top 10. While it is famously difficult to predict who will win that honor, which suggests the award might not be the most robust measure of managerial quality, it’s still good to know that our new metric isn’t coming completely out of left field. And the bottom-10 list also makes sense, as it could pass as a meeting of the Crusty Old Curmudgeons Society: Jerry Narron90 wRM+ is weighted reliever management plus, a measurement of efficient bullpen management, where 100 is average and higher values are betterSource: FanGraphs, Baseball Prospectus Manny Acta87 Joe Torre113 NAMEWRM+ Joe Girardi111 Fredi Gonzalez108 Bob Geren108 Eric Wedge105 The best bullpen managers since 2000 Tony La Russa92 MANAGERWRM+ Bud Black106 As September draws to a close with multiple teams still locked in tight playoff races, baseball fans across the country have ample reason to pore over every last detail of their managers’ decisions. And when it comes to bullpen management, they have a great deal to scrutinize. Mistakes in this arena — which, by definition, almost always occur late in games — usually come in the form of either saving an ace reliever for “his inning” even as the game slips away at an earlier stage, or, conversely, wasting top relievers by deploying them in unimportant situations.Earlier this month, we showed that major league managers have gotten better at avoiding these types of errors over the past three decades. Instead of handing big moments to subpar relievers based on tired notions of seniority,1Such as age, career saves or years of big-league experience. managers are increasingly handing important responsibilities to the best relievers available. But not every manager is equally adept at doing this. Grading individual skippers on their ability to consistently deploy their best relievers in the biggest moments, we find that bullpen management is a repeatable skill that can be fairly assigned to individual managers, and that good bullpen management is worth something on the order of one win per season.Here’s how it worked. First, we ranked the relievers on each team2Excluding relievers who switched teams midseason. in every full season since 20003Moving the cutoff up from 1988 in order to focus on managers who are still relatively fresh in the collective memory. from best to worst in deserved run average (DRA), which is Baseball Prospectus’s context-neutral metric for evaluating pitcher performance.4The stat accounts for, among other things, weather, team defense and umpire performance. We then ranked those same pitchers by the average leverage index — essentially, the importance (and pressure) of the moment — at the point when they first entered the game.5We pulled leverage index data from Fangraphs. Finally, we checked how well each team’s ranking of relievers by leverage index matched its ranking by DRA, a correlation6Specifically, a Spearman correlation weighted by innings pitched. we’re calling a team’s reliever management (RM) score. Effective bullpen managers use their best relievers (those with the lowest DRAs) in the most important moments (those with the highest leverage index), which pushes the RM score toward an ideal of -1.In our last article, we refrained from assessing the reliever usage of individual skippers because we weren’t sure yet whether what we were grading was attributable to the manager’s ability or whether it was just a function of the bullpen he had at his disposal in any given year. So we decided to test that relationship out. If reliever management is indeed a skill, we’d expect to see the same group of skippers be good at it — or bad at it — year after year. You don’t wake up one morning and forget how to drive a car, but sometimes you do hit every red light on your commute to work, or, in this case, get handed a bad batch of relievers.After calculating each team’s RM score, we assigned it to their manager of record that season (the one who managed the most games). Then we looked at whether individual managers’ RM scores were correlated with each other from year to year. Although the effect we found was rather weak — only about 10 percent of the variation in RM score year-over-year is likely attributable to managerial choices — it was statistically significant, even two years out.7We found p-values under 0.02 in both our year-over-year and two-year correlations. So it’s reasonable to assign at least some credit (or blame) for a team’s RM score to the man in the dugout.Still, there’s so much variation in team RM scores from year to year that we needed to use a more sophisticated statistical model to estimate each skipper’s overall bullpen-management ability.8Specifically, we used a Gaussian random effects model with terms for the manager and the year, since we previously determined that bullpen management was a skill that managers are increasingly improving at. A random effects model, in contrast to a fixed-effects model, assumes a great deal of statistical noise around an uncertain mean, then strips that noise away to estimate, as accurately as possible, a “true talent” level over time. When we applied our chosen model to each manager’s raw RM scores for each season, we ended up with an aggregate measure of how likely any given manager was to optimally match their relievers to appropriate situations — good relievers to tense moments, worse relievers to calmer ones.We’re calling the resulting metric weighted reliever management plus (wRM+), and in the style of other “plus” statistics, it’s been rescaled for ease of interpretability: 100 is average, with numbers above 100 corresponding to the percentage factor by which a manager is better than average (or worse than average, for scores below 100). For example, Joe Torre grades out as the best manager since 2000 with a score of 113, meaning his bullpen management was 13 percent better than average. Here’s the rest of the top 10:9To be especially sure we were isolating managerial skill, we limited the table to only include skippers who have managed at least five seasons since 2000. Ozzie Guillen111 Bob Melvin93 Clint Hurdle90 Ron Washington94 John Gibbons91 Jim Tracy108 Bobby Valentine93 Bruce Bochy108 Jim Leyland92 Dusty Baker91 The worst bullpen managers since 2000 Buddy Bell105 wRM+ is weighted reliever management plus, a measurement of efficient bullpen management, where 100 is average and higher values are betterSource: Fangraphs, Baseball Prospectus Several of these guys are on the record as advocating innings-based roles, which are the bane of optimal relief management. But even the worst bullpen managers can change their philosophies over time. Hurdle went from having one of the worst RM scores in the league in Colorado to having one of the best in Pittsburgh. His overall ranking is more of a testament to his earlier difficulties than to his current acumen, and to the influence that front offices can have on managerial decision-making.So, now that we have a means of grading individual managers on reliever usage, how much is that actually worth in terms of wins and losses? To answer that, we looked at how many fewer runs were allowed — which in turn points to how many extra games were won — by good bullpen managers versus bad ones, sketching out a rough estimate of how many additional wins a manager’s bullpen smarts have been worth to his team.10For every team in our sample, we looked at how many runs the team gave up and how much the team over- or underperformed its run differential. We found that raw RM scores were significantly — if also weakly — correlated with both runs allowed (with an r of 0.11 and a p-value of 0.015) and whether a team over- or underperformed its run differential (an r of 0.12 and a p-value of 0.02). We used linear regressions of RM scores on these two numbers — and the fact that each win is equivalent to about 10 runs — to derive a total run value for bullpen management.Perhaps surprisingly, we found that bullpen management — good or bad — doesn’t actually affect a team’s overall performance all that much. Certainly it’s not as important as, say, having good relievers to employ in the first place. A manager who’s bad at managing a bullpen (for example, Manny Acta) might be expected to win about 0.5 fewer games per season as a result of his bullpen-management problems than an average manager with the same ’pen, while a good one (such as Joe Girardi) might win 0.5 games more than average over the course of a season. The total effect of this skill has a range of perhaps one win per year.In other words, bullpen management isn’t the be-all and end-all of managerial skills. That fits with what we already knew about managers: How they shape the chemistry and morale of the team tends to be vastly more important than their on-field tactical machinations, no matter how high-profile those machinations might be. And since every team is getting better and better at using their bullpen, the range of this skill is likely to shrink even further. And, more to the point, the single biggest determinant of team success, now and forever, remains the same: player quality.The usual caveats, discussed in greater detail in our earlier article, still apply.11Notably, our simple correlation-based metric doesn’t take into account matchups, reliever fatigue or bullpens changing over the course of a year. What’s more, for now we’re laying all the responsibility for the bullpen at the feet of the manager, when the front office and pitching coach probably also play a role. And our particular ranking method doesn’t account for fluctuations in reliever performance throughout the season — a guy who’s good in the first half but terrible in the second will be viewed as the average of the two — or for bullpens where the range of talent available to the manager is not wide (which makes for less obvious choices).Still, we can say this with some certainty: Effective bullpen management is a skill attributable at least in part to managers, and is not just the result of random variation. Moreover, some managers are far better at handling their bullpens than others, probably to the tune of a win or so at the margins every year (which is not nothing — consider the tight wild-card races in both leagues this year). So your deepest suspicions about bullpen usage were always correct — unless you’re a Braves fan, in which case it’s probably worth sending a note of apology to Fredi Gonzalez.CORRECTION (Sept. 21, 4:35 p.m.): A table in an earlier version of this article incorrectly listed Dale Sveum among the worst bullpen managers since 2000. Sveum shouldn’t have qualified for the list because he managed fewer than five MLB seasons during that period. read more

Ohio State womens hockey desperate for offense in series at Minnesota State

OSU senior forward Julia McKinnon (17) controls the puck during a game against Minnesota on Oct 16 at the OSU Ice Rink. Credit: Courtesy of OSUThe turn of the calendar hasn’t translated to better results for the Ohio State women’s hockey team, but it will get a two-game crack over the weekend against the bottom-feeder of the Western Collegiate Hockey Association.OSU (7-17-0, 3-15-0) is set to travel to Mankato, Minnesota, over the weekend to take on Minnesota State. The Buckeyes swept the Mavericks (3-19-2, 0-17-1) in a home series in October, and they hope to have the same success this weekend. The Scarlet and Gray enter the weekend having only won one game in their last six contests, but they hold strong with the belief that their work in practice will begin to translate into in-game success.“We haven’t really let off the gas pedal as far as working the girls,” OSU assistant coach Carson Duggan said. “They’ve had a couple of really tough days of practice as far as battling and skating, and their work ethic has been great.”The Buckeyes are on an eight-game winning streak against the Mavericks and they believe that outworking their opponent will help extend the streak to 10 after this weekend.“First and foremost we have to outwork them,” Duggan said. “I thought this past weekend we played a really good brand of hockey and we just have to continue doing that and focus a little more on bearing down and putting pucks in the back of the net. Stick to our gameplan and we’ll hopefully have a successful weekend.”Struggling to light the lampLast weekend, OSU outshot St. Cloud State 25-20 in the first game and 37-17 in the second, but lost both contests 2-1. The team has been happy with its improved offensive production in terms of shots but is still looking to score more goals.“This week we’ve definitely focused on getting those gritty goals,” senior forward Julia McKinnon said. “Not all goals are going to be nice, so I think just getting greasy goals and going to the front of the net and continuing to shoot, one of them are going to go in.”Duggan said she thinks that beyond the ability to score goals, the team also needs to have the drive to put the puck in the back of the net.“It’s a skill but it’s also a will to want to score, you have to bear down and we’ve been really preaching that this week in practice,” Duggan said. “Some of the drills we’re doing are catering to getting more of those garbage goals around the crease versus just the shots from the outside.  I think not staying on the perimeter as much and trying to insert ourselves more into the slot area. So that’s been a priority this week in practice and hopefully that translates this weekend.”OSU has scored just three goals in the last four games, so the team has made that one of the most crucial elements to improve upon.“You can’t win games only scoring one goal a game,” McKinnon said. “I think just moving forward we have to get those goals because you can’t win one-goal games”In the second game of the October series, OSU shut out Minnesota State. Duggan said she believes staying strong defensively depends on eliminating shots off rebounds.“If we continue to stick to the systems and play tough defense, let (sophomore goalie) Alex (LaMere) see all the shots and eliminate their second and third chances, I think that’s the recipe for success defensively,” Duggan said. “The girls know that, so I think they should be ready defensively.”The puck is scheduled to drop in Mankato at 3:07 p.m. on Friday and Saturday.Up nextOSU will continue to set up temporary residence in The North Star State the weekend after taking on the Mavericks when it is slated to travel to Duluth to face OSU coach Jenny Potter’s alma mater, Minnesota Duluth, which swept OSU in December. Puck-drop is scheduled for 8:07 p.m. on Jan. 29 and 5:07 p.m. the following day. read more

Hawaii Volcano Erupts From Summit Sends Huge Plume Into Sky

first_imgOfficials have said they didn’t expect the explosion to be deadly as long as people remained out of the closed national park. The explosion came after two weeks of volcanic activity and the opening of more than a dozen fissures east of the crater that spewed lava into neighborhoods, said Mike Poland, a geophysicist with the U.S. Geological Survey.

New optical technique able to detect a single radio signal amongst background
New optical technique able to detect a single radio signal amongst background

first_img(Phys.org)—A small team of researchers with the University of California has found a way to pick out a single short radio signal burst among a barrage of background noise. In their paper published in the journal Science, the team describes their technique, how it works, how accurate it is and the possible applications it might be used for. Michael Vasilyev, with the University of Texas offers a Perspectives piece on the work done by the team in the same journal issue, noting how some human organs have senses that rely on using a similar technique to make sense of the environment.

Heralded by weak signals, hidden in noise, they pose basic detection challenges. In contrast to repetitive waveforms, a single-instance signal cannot be separated from noise through averaging. Here, we show that a fast, randomly occurring event can be detected and extracted from a noisy background without conventional averaging. An isolated 80-picosecond pulse was received with confidence level exceeding 99%, even when accompanied by noise. Our detector relies on instantaneous spectral cloning and a single-step, coherent field processor. The ability to extract fast, subnoise events is expected to increase detection sensitivity in multiple disciplines. Additionally, the new spectral-cloning receiver can potentially intercept communication signals that are presently considered secure.Press release © 2015 Phys.orgcenter_img As Vasilyev notes, there are a lot of areas in science that could benefit from an ability to isolate a single short signal amongst a stream of noise—astronomy, is just one example. Currently it is impossible to separate out a unique signal if there is just one burst present—there needs to be multiple examples. That could change in the near future as the researchers on this new effort have developed a way to convert radio signals to optical signals that can be processed to filter, separate and identify individual components.The team started with converting the radio signals to optical signals because the latter are more sensitive to changes in frequency—to make the conversation, the team looped the signals so that they could gather enough data for averaging. Next they used two tunable optical frequency combs—when the spectrums were overlapped it allowed for alignment of the components which caused the signal to be amplified as compared to other background noise, which then allowed it to be uniquely identified. The team tested their technique by running 4,720 detection attempts and found it to be better than 99 percent accurate.The researchers believe their technique can be broadened to include the detection of a wide variety of signals, from optic applications to those that look for microwaves. It could also possibly be modified for use in seemingly unrelated research areas such as sensing the spontaneous decay of a molecule. There also exists the possibility that the new detector could be used to spot signals that to date have gone undetected, perhaps revealing the existence of some new type of phenomena.

It has a central supermassive black hole (SMBH) with an estimated mass of around 20 million solar masses.In general, Seyfert galaxies host active galactic nuclei (AGN) that produce spectra line emissions from highly ionized gas. Astronomers classify these galaxies as type 1 or 2, depending on the emission lines shown by their spectra.However, observations show that various AGN types are observed in the same object at different epochs of time. One explanation of this phenomenon is that some type 2 Seyfert galaxies are actually type 1 with inactive engines. This suggests that type 2 Seyfert galaxies are an evolved version of the type 1.Some AGNs showcase X-ray absorption variations, and are thus called “changing-look” AGNs. Furthermore, in some Seyfert galaxies, the broad emission lines disappear and, while in others broad emission lines appear, what astronomers describe as a “turn-on” of an AGN. So far, the most rapid “turn-ons” observed last less than one year.Now, a team of researchers led by Reza Katebi of Ohio University reports a rapid “turn-on” of the nuclear transient PS1-13cbe in the nucleus of the galaxy SDSS J2221+0030. PS1-13cbe was detected on July 9, 2013 in the Pan-STARRS1 (PS1) sky survey. Additional observations of this transient and its host galaxy, that led to the new findings, were conducted by the team using NASA’s Swift spacecraft, the 6.5 m Magellan Clay telescope and the 2.4 m Hiltner telescope.According to the paper, PS1-13cbe brightened in the course of about 70 days and reached a peak total optical luminosity of approximately 10.6 tredecillion erg/s, while its temperature roughly stayed constant. Moreover, this rapid “turn-on” of PS1-13cbe was accompanied by the appearance of broad Balmer lines and hence a transition to a type 1 Seyfert galaxy.”At the time of the outburst, the galaxy changed type to a Seyfert 1 as broad Hα and Hβ appeared and the continuum brightened in the spectrum taken with LDSS3 +57 days after the peak and then changed its type back to a Seyfert 2 as the broad Hα and Hβ disappeared in the spectrum taken with OSMOS 2 years later and did not reappear in spectra taken three and four years after the outburst,” the researchers wrote in the paper.The observations allowed Katebi’s team to conclude that PS1-13cbe is a “changing-look” AGN that has been powered by instabilities in the accretion disk. They added that the “turn-on” of this AGN is among the shortest observed in a “changing look” active galactic nuclei.last_img read more

Cloudbased broadcast infrastructure provider Amag

first_imgCloud-based broadcast infrastructure provider Amagi will make its international debut at IBC next month with the launch of next generation services for broadcasters and content owners.
Amagi uses the cloud to change the way TV networks distribute their content. Its transmission infrastructure can use secure private clouds to push and store content ahead of time to affiliate headends across the globe.At IBC, the company will launch two new services, including a barcode system for audio-video content that can enable identification of specific content assets. The barcodes are watermarked on the content to uniquely identify any of the assets on the network feed.Amagi’s new localisation service uses this barcoding system to enable broadcasters and content owners to localise programming and ads in different regions covered by a common satellite feed. Content to be replaced locally is barcoded and local replacement content is sent via the cloud to the relevant broadcast headend ahead of transmission. The network feed is then played out with the barcoded content and Amagi content insertion devices at each of the affiliate headends detects the barcode and splices in the replacement content as appropriate.Also launching at IBC will be Amagi’s cloudporting service that enables playout of a TV channel across multiple headends using Amagi’s cloud-based transmission infrastructure. The transmission schedule and all relevant content is pushed to each broadcast headend via Amagi’s private cloud using a web-based user interface. The content and playlist are stored in an Amagi content playout device at affiliate headends and played out as listed.Amagi will be exhibiting at IBC on Stand 3.C31last_img read more
