BEIJING (AP) The Latest from the IAAF world championships (all times local):
Sebastian Coe officially replaced Lamine Diack as president of the IAAF on Monday, and he got to work right away.
In a statement released a minute after midnight, Coe marked his ''first day of office'' by promising a new era of governance.
''I am determined to get out of the starting blocks quickly, so today we begin a detailed review of our existing management structures and use of resources to ensure that within the next 100 days, IAAF Council can approve new systems and teams which are necessary for delivering our ambitious plans,'' Coe said.
Coe was elected at the IAAF congress three days before the world championships began in Beijing, beating Sergei Bubka in a vote of more than 200 member federations. The two-time Olympic 1,500-meter gold medalist, a key organizer of the London Olympics in 2012, wants to create an independent anti-doping tribunal among the overhauls of the sport's governing body.
''We are committed to ensuring good governance in everything that we do and, as a starting point, our legal team has been asked to conduct an in-depth review of the IAAF Constitution and related governance,'' Coe said.
Now, what do you take home when you've been away while your wife was giving birth to your first child?
A world championship medal would be a good start.
Martyn Rooney had to chase down Jevon Francis of Jamaica right up to the line in the 4x400-meter relay and dip hard to beat him by .004 seconds to earn Britain a bronze behind the United States and Trinidad and Tobago.
''There was no way I wasn't going to fight all the way down the home straight,'' Rooney said. ''I just wanted that medal more than anything.''
Lucky for him, his wife is understanding when it comes to his untimely absence. Kate Rooney, formerly Dennison, is the former British pole vault record holder.
Rooney, meanwhile, is still considering names.
''When I get to hold him, then we will see,'' the happy father said.
LaShawn Merritt anchored the U.S. men's 4x400-meter relay team to a sixth straight world title, winning in 2 minutes, 57.82 seconds to end a relay drought for the Americans at the Bird's Nest.
Jamaica won the men's and women's 4x100 relays and the women's 4x400 and was leading the final race on the final lap until Merritt overhauled Javon Francis and went on to win comfortably.
Trinidad and Tobago earned silver in a national record 2:58.20 and Britain edged Jamaica for bronze.
Derek Drouin of Canada won the world high jump title in a jump-off Sunday, clearing 2.34 meters after three competitors fouled out at 2.36 without missing at any previous heights.
Bohdan Bondarenko of Ukraine, the 2013 champion, and Zhang Guowei of China shared silver after failing to clear 2.34.
Jamaica regained the lead in the last 40 meters to beat the United States for the gold medal in the women's 4x400-meter relay.
Allyson Felix, the 400-meter champion who was chasing her 10th world championship gold, ran an impressive third leg to chase down Jamaica's big lead and put the United States ahead at the final baton change.
But the Jamaicans won in 3 minutes, 19.13 seconds, 0.31 seconds ahead of the Americans. Britain finished with the bronze in 3:23.62.
Kathrina Molitor of Germany won the women's javelin world title with the last throw of the final on Sunday, relegating Lyu Huihui of China to silver.
Lyu took the lead with her fifth attempt, surpassing Sunette Viljoen of South Africa with a mark of 66.13 meters and prompting a noisy roar from the crowd at the Bird's Nest. She didn't improve on the mark on her final attempt and Molitor threw 67.69 to win.
Viljoen finished with bronze with a best mark of 65.79. Defending champion Christina Obergfoell was fourth at 65.61.
Barbora Spotakova of the Czech Republic, a two-time Olympic champion and world-record holder, didn't throw well enough to make the last eight and get an extra three throws. Her best throw was 60.08, leaving her in ninth place.
Asbel Kiprop won his third world title in the 1,500 meters and collected another gold medal at the Bird's Nest, where he won at the 2008 Olympics.
Kiprop surged from fourth into the lead halfway down the last straight and won in 3 minutes, 34.40 seconds. Kenyan teammate Elijah Manangoi was second in 3:34.63 and Abdalaati Iguider of Morocco was third.
Almaz Ayana won the 5,000-meter final on Sunday in a world championship record 14 minutes, 26.83 seconds, leading an Ethiopian sweep of the medals.
With four laps to go, Ayana made a move and started to lift the pace, leaving Genzebe Dibaba behind. With two laps to go, she led by 50 meters.
Dibaba, who won the 1,500-meter title and was aiming for a distance double, was edged for the silver by Senbere Teferi, who finished in 14:44.07. Dibaba was 0.07 seconds behind for the bronze medal.
Kenyan runners finished fourth, fifth and sixth.
Fear the beard. Or at least half of it.
Italian higher jumper Gianmarco Tamberi shaved only half his face for the event at the world championships.
Depending on where you're sitting in the stands, he's either clean shaven or has a couple of day's growth.
Tamberi has done this before, once saying of the interesting look: ''I like to be on stage to entertain the audience.''
In 2012, he had blue hair for the European championships.
IAAF president-elect Sebastian Coe thinks the performances of the likes of Usain Bolt, Mo Farah and Ashton Eaton should be the focus of competition, not the doping.
''We're more than a discussion about test tubes, blood and urine,'' Coe said a news conference Sunday that was called to wrap up the world championships and bid farewell to 82-year-old Lamine Diack, who is standing down after 16 years as IAAF president.
Bolt successfully defended his 100- and 200-meter titles and anchored Jamaica's 4x100-meter relay team. Farah completed a long-distance double in the 5,000 and 10,000. Eaton broke his own world decathlon record.
News in the months leading up to the world championships in Beijing was overshadowed by criticism of the IAAF's handling and management of the anti-doping program.
The gold medal was cool. The $100,000 - pretty nice, too.
In addition to receiving the usual prize for winning a world championship at the medals ceremony Sunday, American decathlete Ashton Eaton also picked up a poster-sized check for $100,000 - the bonus the IAAF gives to athletes who set a world record.
Eaton broke his own mark Saturday by scoring 9,045 points, closing things out with a 1,500-meter run in 4 minutes, 17.52 seconds to put him over the top.
Qatari high jumper Mutaz Essa Barshim, along with five other competitors and former stars, was elected by his peers to serve on the IAAF athletes' commission.
Barshim is joined by New Zealand shot putter Valerie Adams, Russian pole vaulter Yelena Isinbayeva, Japanese hammer thrower Koji Murofushi, Swedish triple jumper Christian Olsson and Norwegian javelin thrower Andreas Thorkildsen.
Mare Dibaba won the first women's marathon title for Ethiopia at the world championships Sunday, holding off Helah Kiprop of Kenya in a sprint to the finish.
Dibaba finished in 2 hours, 27 minutes, 35 seconds, but needed to pick up the pace after entering the stadium to beat Kiprop, who finished one second behind. Eunice Kirwa of Bahrain earned the bronze.
Two-time champion Edna Kiplagat was in contention until the end but faded to fifth place.
In the shadow of the Bird's Nest, Dibaba kept checking her watch. Then, she made her move and raised her arms after crossing the line.
Risa Shigetomo of Japan and Kim Hye Song of North Korea led a tightly bunched field halfway through Sunday's marathon at the world championships.
There were 14 runners within a second of the lead, including two-time defending champion Edna Kiplagat of Kenya. American runner Serena Burla was three seconds back on a cloudy morning.
The air quality wasn't exactly conducive to running a marathon, with it starting at the ''moderate'' level and falling into the ''unhealthy for sensitive groups'' range.
The women's marathon at the world championships began Sunday under hazy skies and with the air quality listed at a ''moderate'' level.
Edna Kiplagat of Kenya is chasing a third straight title.
The weather is supposed to be about 21 degrees Celsius (70 degree Fahrenheit) with overcast conditions. The men's marathon to start the championships was clear and the U.S. Embassy Beijing Air Quality Monitor listed the air quality as ''good'' for the race.
The ''moderate'' level means that ''unusually sensitive individuals may experience respiratory symptoms.''
