More than 6 billion people live in countries where serious levels of public sector corruption are fueling inequality and exploitation, according to Transparency International's 2015 index of perceived public sector corruption. The group's annual report measures perceptions of corruption due to the secrecy surrounding most corrupt dealings. Two thirds of the 168 countries assessed were identified as having a serious corruption problem. Somalia, which has been mired in conflict since civil war broke out in 1991, ranks bottom of the list.

Emilia Pechinkova, a 24-years-old Bulgarian Pomak (Bulgarian speaking Muslims) bride poses for a photograph following the “gelina” or face painting ceremony carried out by female guests and relatives in preparation for her three-day wedding ceremony in the village of Draginovo, 100 kms southeast of Sofia on April 22, 2016. Bulgaria's Muslim population is one of the highest in the European Union. During the Communist regime religious rituals were not tolerated, and Muslims were forced to abandon wearing their traditional wedding outfits. Recently, more young Pomak women want to include traditional wedding customs that were forbidden during the regime, regardless of their secular lifestyles and the high cost of such a wedding.

People throw turnips at the Jarramplas as he comes out from the church beating his drum during the Jarramplas Festival on January 20, 2016 in Piornal, Caceres province, Spain. The centuries old Jarramplas festival takes place annually every January 19-20 on Saint Sebastian Day and this year they expect to use more than 20 thousand kilogrames of turnips. Even though the exact origins of the festival are not known, various theories exist including the mythological punishment of Caco by Hercules, a relation to ceremonies celebrated by the American Indians that were seen by the first conquerors, to a cattle thief ridiculed and expelled by his village neighbours. It is generally believed to symbolize the expulsion of everything bad. (Photo by Pablo Blazquez Dominguez/Getty Images)

The large-scale immersive series of performances took more than a year of careful planning and consists of two parts: a daytime performance and a 90-minute night performance, they added.

Behaviour: Mammals category. Giant Gathering by Tony Wu, USA. Dozens of sperm whales mingled noisily off Sri Lanka’s northeast coast, stacked as far down as Tony could see. This was a congregation of dozens of social units, like a gathering of the clans. Aggregations like this could be a critical part of the whales’ rich social lives but are rarely reported. Some two thirds of the population was wiped out before commercial whaling was banned in 1986. This kind of major gathering could be “a sign that populations are recovering”, says Tony.

Sеx worker Geraldine, wearing cat make-up, excitedly holds up a dress she is thinking of buying from a street vendor, so that her partner, sitting nearby to keep her company, can see it, as she waits for clients outside the Revolution subway station, in Mexico City, Saturday, March 13, 2021. According to Geraldine, 30, the pandemic has cut clients and increased risks to the sеx workers but has also brought out more assistance for them too, both from dedicated organizations such as the activist group Brigada Callejera or “The Street Brigade” and from individuals who have donated food or clothing.
