Dynam employees bow in a prescribed way as they receive customer-care training ahead of the grand opening of the company's pachinko parlour in Fukaya, north of Tokyo July 29, 2014. Japan's once-booming pachinko industry, grappling with a greying customer base and the threat of new competition from casinos, is adopting a softer touch and smoke-free zones to lure a new generation of players, particularly women. Pachinko, a modified version of pinball, is a fading national obsession, with about 12,000 parlours nation-wide and one in thirteen people playing the game. But that figure is declining as the population shrinks and younger people prefer games on their mobile phones. Picture taken July 29, 2014. REUTERS/Issei Kato (JAPAN - Tags: SOCIETY BUSINESS)

Player Nathalie Quezada (L) of the Colo Colo women's soccer club receives medical attention from a trainer before a match in Santiago May 11, 2014. Long on the soccer sidelines, more and more South American women are striking back by lacing up their boots and embracing the region's most cherished sport. The surge is part of a global boom, with an estimated 29 million women and girls playing worldwide. But it is especially salient for South America, a region revered for its ball game and infamous for its machismo. To match Feature SOCCER-LATAM/WOMEN Picture taken May 11, 2014.

A Trek employee demonstrates the Ai Ball wifi video camera in Singapore December 19, 2012. Singapore's decade-long push to become a hotbed for entrepreneurs is stuck at stage one. Venture capital firms are put off by the small size of the market, lack of big ideas that can be a global success and an uncertain exit strategy. Only 50 out of 301 venture capital firms based in Singapore are interested in local investment, according to the Asian Venture Capital Journal Research. Of the 70 high tech start-ups the government has invested in over the past two years, just 10 received follow-on private funding from investors locally and abroad, according to the National Research Foundation, the government arm responsible for research and development.

Spanish migrant Olmo del Paso smiles as he receives a handmade wallet from his girlfriend Marta Perez while going to Madrid's Barajas airport October 23, 2012. Del Paso is a cameraman who left Spain for Uruguay this month after being jobless for over two years and being forced to move back into his mother's house in the small northern town of Palencia. When a hotel in Montevideo, Uruguay, offered him a job as caretaker over the summer months, the 34-year-old bought a one-way ticket and packed his bags. After joining the euro in 1999, Spain's economic boom made it the land of opportunity for millions of Latin American migrant workers. But since the decade-long boom turned to bust roughly four years ago, many of those immigrants have returned, joined by a growing number of disillusioned Spaniards who hope that Latin America, with its developing economies and low cost of living, has more to offer.

Cars queue for petrol at a gas station in Dubai June 11, 2012. In the Gulf, the oil price slide threatens to cool an 18-month economic boom that helped the region recover from the global financial crisis of 2008-2009. In addition to receiving lower oil prices, Gulf oil producers - particularly Saudi Arabia - may have to cut the volumes they sell to prevent a deeper drop of prices. So far, however, most Gulf economies look likely to continue expanding at comfortable rates with cheaper oil. In the wake of the recent slide in the price, the UAE's Economy Minister Sultan bin Saeed al-Mansouri last week cut his forecast for this year's GDP growth to around 3 percent, from the almost 4 percent which he predicted in March.
