Kinship: In anthropology, kinship is the web of social relationships that form an important part of the lives of most humans in most societies, although its exact meanings even within this discipline are often debated.  Anthropologist Robin Fox states that "the study of kinship is the study of what man does with these basic facts of lifemating, gestation, parenthood, socialization, siblingship etc." Human society is unique, he argues, in that we are "working with the same raw material as exists in the animal world, but [we] can conceptualize and categorize it to serve social ends."  These social ends include the socialization of children and the formation of basic economic, political and religious groups.

Sylvette: Sylvette is the title of a portrait painting by Pablo Picasso, featuring a young woman with a pony tail.  The model for the painting, Lydia Sylvette David, also known by her married name Lydia Corbett, was a French woman who, during the summer of 1953, worked in a pottery studio near Picasso's studio in Vallauris.  Finding her appearance appealing, Picasso created 40 works inspired by her.  Sylvette's portrait from 2 May 1954 is one of the last of a long series.  Picasso's grandson Olivier Widmaier Picasso told the "Chicago Sun-Times" in 2004 that Sylvette was also the subject of the monumental Chicago Picasso, which had been a matter of curiosity since it was unveiled.  She was said to have been an inspiration for actress Brigitte Bardot and the Roger Vadim film "And God Created Woman".
