Past prominence of course does not guarantee continued success. Metro areas as diverse as Detroit, Manchester, and Rome have all become less globalized compared to their previous peak. Equally, others are proving that it is never too late to take advantage of changing dynamics. Metro areas that seize the historical moment can achieve lasting benefits. Toronto is an example of a metro that responded purposefully to a convergence of unique circumstances between 1945 and 1970.

British PR consultants talk Russia into battling “anti-Russian propaganda” in the UK – and paying them for it

Gastrodiplomacy is an increasingly popular form of public diplomacy that uses food as a means to communicate culture; this tactic of culinary cultural diplomacy shares the uniqueness of a country's cuisine as a manner of edible nation branding.

Brazil has something of an identity crisis right now. As protests continue, the world has been exposed to the massive social unrest in the country over inequality, corruption, and the adverse economics of preparing to host global sporting events like the upcoming World Cup.

His relatives also were embroiled in two lawsuits to secure control over his trust funds and the burial places of the remains of three of his children.

The contrast between LA and another great city, Seoul, is remarkable. I have been going to Seoul for about 20 years now, and I just brought a group of USC students there for a comparative international development class. Back in 1992, when I first visited Seoul, it was an emerging city of considerable promise, but also with considerable poverty. It has since become one of the world’s rich cities.

The XXXII Olympic Summer Games in 2020 will be hosted by one of three candidate cities: Madrid, Istanbul, or Tokyo, following the 2016 games in Rio De Janeiro. The three candidates were selected by the International Olympic Committee out of a group that also included non-selected applicant cities Baku, Doha, and Rome (which withdrew its bid shortly before the applicant files were due).
