Earlier this week, we read with interest in The New York Times that Davidson College’s math department is helping its men’s basketball team win games. Since this combines three of our favorite subjects — sports, math and using math to win at sports — I asked Tim Chartier, a professor in Davidson’s mathematics and computer science department, to elaborate on the unusual partnership between his department and the Wildcats.He was understandably reluctant to spill too many details — particularly regarding how the math department analyzed the data about Iowa, Davidson’s round-of-64 opponent in the NCAA tournament Friday, or Gonzaga and North Dakota State, one of which Davidson will face if it reaches the round of 32 and both of which he’d already started scouting. But Chartier did shed a little more light on the math behind the surprise Atlantic 10 champs. And it sounds a lot like what we do at FiveThirtyEight, except with a goal of winning basketball games instead of writing articles about winning basketball games. Here are edited excerpts of his reply:So, what do we offer the coaches?Heat maps: Two members of Cats Stats, as we call our group, track the games for heat maps. They mark who takes a shot and estimate the location by clicking a computer program that I wrote. Then, as you see, regions of the court are marked as hot and cold regions. Two members of the group met with coaches in January and went through heat maps not just at the team level but player level and then various combinations of players. The coaches found this very helpful and discovered things that led them to analyze player combinations with similar tendencies that they then recognized.Lineup efficiencies: Here we show Dean Oliver’s Four Factors for offense and defense for every five-man lineup and the total amount of time that lineup has been used. Then, we also found various subsets of lineups, as well, like guard trios and forward pairs. For example, we might see that two big men are most efficient/inefficient when in the game together.Personal scouting: Here we produce a detailed breakdown of players’ tendencies and how well they performed in each aspect of the game. Here no new statistics were created. We presented data and numbers so that the coaching staff could easily implement the reports into their game plan. It could range from things like whether or not a player liked to shoot off the dribble and how effective they were in those situations to things like how effective a player might score driving left out of isolation situations. Said another way, we look for the tendencies in the numbers, especially outlier numbers. We think of these as creating data points or dots. Then, we dig into the video that accompany these stats on Synergy and figure out the story/tendency behind the number. That gives context and, in a sense, connects the dots. For example, if a player drives to the right 80 percent of the time and scores much better than going left, that is important. But, then the video can help see that his first step when driving is quicker going right than left, allowing him to beat his man more often.
6969Prime Minister Minnis addresses the 5th Meeting of ACP Ministers in charge of Fisheries and Aquaculture, September 20, at Melia Nassau Beach resort. Facebook Twitter Google+LinkedInPinterestWhatsApp Facebook Twitter Google+LinkedInPinterestWhatsApp#Bahamas, September 21, 2017 – Nassau – Climate Change is now one of the most fundamental development challenges facing countries of the African, Caribbean and the Pacific (ACP) grouping, Prime Minister, Dr. the Hon. Hubert A. Minnis said Wednesday.Addressing the Opening Session of the 5th Meeting of ACP (Africa, Caribbean and Pacific) Ministers In Charge of Fisheries and Aquaculture at Melia Nassau Beach resort, Prime Minister Minnis said various climate models suggest damage from natural disasters have increased sharply and that: “such damage is likely to worsen, especially from flooding.”“The National Wildlife Federation in the United States notes that the latest science connecting hurricanes and global warming suggests more is yet to come,” Prime Minister Minnis said.“Tropical Storms are likely to bring higher wind speeds, more precipitation and bigger storm surge in the coming decades.”Prime Minister Minnis observed Climate Change also poses risks for sustainable development and tourism, in addition to sustainable fisheries.“In meeting these risks, we must rise to the challenge with new ideas for fisheries and aquaculture.“Public and private sector investments are required if the aquaculture sector is to develop in a viable manner in the Caribbean. The Caribbean Community must do its part to boost aquaculture and sustainable fisheries throughout our region,” Prime Minister Minnis added.The Prime Minister announced that the Government of The Bahamas will promote investments in aquaculture, mariculture and modern sea farming strategies.It will undertake a study of the country’s marine resources with a view to creating opportunities for the artificial propagation and enhancement of local fish stocks, addressing growing demands for fish and aquaculture products regionally and globally, and the ‘steep rise’ in importation of fish and fisheries products over the last decade.Prime Minister Minnis said there is no denying the impact Climate Change is having on the 2017 Atlantic Hurricane Season. There have already been 13 named storms just three-and-one-half months into the season, with two-and-one-half months left to go. (The Hurricane Season lasts June 1 through November 30.)Already, there have been three Super-Storm Hurricanes (Harvey, Irma, Maria) that have left an estimated hundreds of billions of dollars worth of devastation and destruction across the region and parts of the United States of America.Maria, the latest of the three Super Storms, has wreaked major havoc in Dominica and Puerto Rico.“Like typhoons and monsoons (in Asia), these Super Storms leave many communities and countries in the Caribbean particularly vulnerable,” Prime Minister Minnis said.“This includes Small-Island Developing States (SIDS) and low-lying areas such as The Bahamas and a number of small-island Pacific States here today. Climate Change is now one of the most fundamental development challenges for countries in Africa, the Caribbean and the Pacific,” Prime Minister Minnis remarked.By: Matt MauraPhotos/Yontalay Bowe, OPM Media Services 6983Group Photo at Melia on Wednesday. 6849Prime Minister Minnis (second left) and Bahamas Minister of Agriculture and Marine Resources Renward Wells (third left) chat with a delegate of the 5th Meeting of ACP Ministers in charge of Fisheries and Aquaculture, September 20, at Melia Nassau Beach resort.

Kolkata: New Town Kolkata Development Authority (NKDA) on Tuesday launched a drive to catch stray cows. The owners of the stray cows will be fined and NKDA authorities feel that the drive will make the owners of the cattle aware that they should not be allowed to roam about aimlessly on the main thoroughfare.Earlier, the New Town Kolkata Development Authority (Amendment) Bill 2018, which empowers the chairman of NKDA to pass orders of seizing cattle that stray in public premises in New Town, was passed by the Bengal Legislative Assembly in March 2018. The notification for the amendment has already been released by the state Urban Development and Municipal Affairs department.

The cattle shed has facilities for feeding the animals, a small administrative office and an open ground for the cattle to graze.The area, spread over 3 acres, is located in Action Area 1D and steps are being taken to frame draft rules regarding fees and procedure to be followed, in confining the animals and releasing them subsequently.

Stray cows pose a serious threat to the smooth movement of vehicles on Biswa Bangla Sarani. Road accidents often occur when the drivers try to save the straying animals. The Biswa Bangla Sarani has witnessed a handful of such accidents in recent times, leading to injury to both cattle and people.The worst accident occurred on October 26, 2017, when six-year-old Deepshika Chakraborty, her father Pravat and his colleague Goutam were killed, after the motorbike they were travelling on skidded off the road, trying to avoid cows near the Akankha Crossing.
The brain data revealed that the infant cries reduce attention to the task and triggered greater cognitive conflict processing than infant laughs. “Parental instinct appears to be hardwired yet no one talks about how this instinct might include cognition,” said David Haley from the University of Toronto.The team looked at infant vocalisations — in this case, audio clips of a baby laughing or crying —and its effect on adults who completed a cognitive conflict task. Also Read – ‘Playing Jojo was emotionally exhausting’They asked participants to rapidly identify the colour of a printed word while ignoring the meaning of the word itself. Brain activity was measured using electroencephalography (EEG), which took place immediately after a two-second audio clip of an infant vocalisation. Cognitive conflict processing is important because it controls attention — one of the most basic executive functions needed to complete a task or make a decision. A baby’s cry has been shown to cause aversion in adults but it could also be creating an adaptive response, “switching on” the cognitive control parents use in effectively responding to their child’s emotional needs while also addressing other demands in everyday life, Haley added in a paper published in the journal PLOS ONE.

The findings add to a growing body of research suggesting that infants occupy a privileged status in our neurobiological programming, one deeply rooted in our evolutionary past. But, as Haley noted, it also reveals an important adaptive cognitive function in the human brain.
