A role model is a person whose "behavior", example, or success is or can be emulated by others, especially by younger people.
 The term "role model" is credited to sociologist Robert K. Merton, who coined the phrase during his career.
 Merton hypothesized that individuals compare themselves with reference groups of people who occupy the social role to which the individual aspires.
 An example being the way young fans will idolize and imitate professional athletes or entertainment artists.
Justine Paris, real name Bienfait (1705-1774) was a French courtesan and madam.
 She hosted several of the most famous brothels in mid 18th-century Paris and was one of the most known and successful of her trade.
 She and her brothel are portrayed in the memoirs of Casanova.
 She has been suggested to be the role model for the title character in "Juliette" by the Marquis de Sade.
Donatien Alphonse François, Marquis de Sade (2 June 1740 – 2 December 1814) (] ), was a French aristocrat, revolutionary politician, philosopher, and writer, famous for his libertine sexuality.
 His works include novels, short stories, plays, dialogues, and political tracts; in his lifetime some were published under his own name, while others appeared anonymously, of which Sade denied being their author.
 Sade is best known for his erotic works, which combined philosophical discourse with pornography, depicting sexual fantasies with an emphasis on violence, criminality, and blasphemy against Christianity.
 He was a proponent of extreme freedom, unrestrained by morality, religion, or law.
 The words "sadism" and "sadist" are derived from his name.
Cesar Mora is an Australian professional vert skater.
 Cesar is the poster boy for professionalism in rollerblading.
 He has strong beliefs in being a role model, as he has never believed in the use of drugs, alcohol, or cigarettes Cesar is the only vert skater to compete in all of the 1st ten X Games.
 In 1998, he won vert gold, and he has two vert silver medals ('95, '99) and a bronze ('00).
 A number one ranked skater and world champion several times.
 Skating for Roces skates from 1994 to 1998 then switching to K2 skates from 1999 to 2004.
 Born in Madrid, Spain, 3 February, and having lived most of his life in Sydney Australia, Cesar represented Australia also in soccer at a youth level, travelling to US and England before landing in his city of birth Madrid and training with professional Spanish side Rayo Vallecano for several months who at the time were in the 4th division of the Spanish league.
 He returned to Sydney and started skating at the beautiful Bondi Beach where he honed his skills on the ramp and launched himself on an international skating career that took him around the world and back several times.
 Always creative, explosive and exciting to watch, Cesar made his mark on many up and coming skaters offering a drug-free life style and a healthy living.
 An artist, not only on the ramp and soccer field, Cesar also loves art, illustration, creative drawing and is a qualified graphic designer.
 His many achievements didn't go un-noticed and at the change of the century he headlined a video game called Roll, sharing the titles with some of the best skaters in the world.
 Sometimes referred to as the king of vert, Cesar pushed the sport in 1998 by being the 1st skater in history to land a 1080 and later on that year a reverse 1260.
 Hailing from the very innovative Australian skating scene he always tried to push the boundaries and try new things, create new ways of performing tricks and innovating, adding his unique style to everything he did, and with these efforts and risks comes injuries, he certainly had his share but somehow managed to avoid broken bones until the end of 2000 whilst performing at the melbourne planet x games he fell and broke his left arm and wrist.
 The physical recovery was fast but the mental recovery took some time, and that year he took on less competitions and concentrated on healing and safety.
 Once the confidence returned the usual big tricks were on display and among the variety of spins, flips and airs for many years he was known for his giant backflips, always a crowd pleaser.
 Cesar, ever the showman, never left a ramp without giving his all, whether it be the x games or a small show in a village in Peru where the ramp may have been less than appropriate.
 He always wanted to leave the kids and fans with something special and signed every autograph.
 He relished his position as a role model and this made him actually wear a helmet, because when he started and on his 1st tour of the states he never liked wearing a helmet and was told no helmet-no skate.
 A proud person with an enviable list of achievements, he relished his time on tour and is always grateful of anyone who helped him along the way.

Juliette is a novel written by the Marquis de Sade and published 1797–1801, accompanying Sade's "Nouvelle Justine".
 While Justine, Juliette's sister, was a virtuous woman who consequently encountered nothing but despair and abuse, Juliette is an amoral nymphomaniac murderer who is successful and happy.
 The full title of the novel in the original French is "L'Histoire de Juliette ou les Prospérités du vice", and the English title is "Juliette, or Vice Amply Rewarded" (versus "Justine, or Good Conduct Well-Chastised", about Juliette's virtuous sister).
 As many other of his works, "Juliette" follows a pattern of violently pornographic scenes followed by long treatises on a broad range of philosophical topics, including theology, morality, aesthetics, naturalism and also Sade's dark, fatalistic view of world metaphysics.
Carrasco was born in El Paso, Texas to Mexican-American parents.
 She was the second-oldest child and oldest girl in her family.
 She had two brothers and two sisters growing up.
 When she was around a year or so of age, her family moved to Los Angeles.
 They lived in government Veteran's housing in Culver City since her father was a Korean War Navy veteran.
 She recalls that they were poor and lived off of food stamps.
 Carrasco's childhood growing up in the predominantly Mexican-American and African-American community of Mar Vista Gardens was sometimes painful, because she was teased for having lighter skin than her peers and stood out for her green eyes; being called "white girl," "green eyes" and ""güera"."
 Her experiences with being simultaneously perceived as not truly Mexican-American and being told to "take advantage of being light skinned" makes up of part of her artistic subject matter later on in life.
 Carrasco said that her father encouraged her to broaden her horizons, go to college and encouraged her artwork.
 He had appreciated art and he was considered artistic.
 Her father, who worked as a bus driver for Santa Monica Bus Lines said that "anybody could be a bus driver but not everybody could be an artist."
 Carrasco's father died of a heart attack when she was twelve and it was difficult for her because she was always close to her father.
 Carrasco's mother, who also volunteered as a Girl Scout leader, was also artistically inclined.
 Her mother admired Japanese art and decorated the house with it.
 Carrasco felt that growing up with Japanese images influenced her sense of line.
 She also felt that her mother was a personal role model because she was a strong woman.
 Her mother was also, however, very protective of her girls, and she expected Carrasco to act as a role model of traditional femininity for her sisters.
