She wrote , directed and produced both of these films . Stickler 's early independent films include the shorts Queen Mercy and the documentary Andre the Giant has a Posse , the first documentary to discover graphic artist Shepard Fairey ( OBEY / GIANT ) . `` Andre the Giant has a Posse '' was screened worldwide and in the 1997 Sundance Film Festival . In 2003 , Village Voice film critic Ed Halter described the film as `` legendary ... a canonical study of Gen - X media manipulation . One of the keenest examinations of `` 90s underground culture '' . Helen is the producer , director , and writer of the feature film `` STOKED : the Rise and Fall of Gator , '' a documentary about 80 's professional skateboarding champion Mark `` Gator '' Rogowski , who is now serving life in prison for rape and murder . STOKED was written about in features in the New York and LA times , and an interview with Helen and former pro skateboarder Ken Park aired on NPR 's `` Fresh Air `` in August 2003 . LA Times critic Kenneth Turan described the film as '' strongly directed and unexpectedly poignant . An excellent documentary about the compelling dark side of the American dream . `` In 1999 Ms. Stickler created the safe sex campaign `` Roll On '' for Mtv and The Kaiser Family Foundation , which earned a Best National PSA Emmy Award nomination . Stickler resides in Los Angeles , California , where she is currently at work on an updated , feature - length documentary about the art and career of Shepard Fairey .  - André René Roussimoff (May 19, 1946  January 27, 1993), best known as André the Giant, was a French professional wrestler and actor.  - Andre the Giant Has a Posse is a street art campaign based on a design by Shepard Fairey created in 1989 in Providence, Rhode Island. Distributed by the skater community, the stickers featuring an image of André the Giant began showing up in many cities across the US. At the time Fairey declared the campaign to be "an experiment in phenomenology". Over time the artwork has been reused in a number of ways and has become worldwide. At the same time, Fairey altered the work stylistically and semantically into the OBEY Giant.    'helen stickler' is related to which object entity through the relation of 'educated at'?

Q: Information:  - Scuba diving is a mode of underwater diving in which the scuba diver uses a self-contained underwater breathing apparatus (scuba) which is completely independent of surface supply, to breathe underwater. Scuba provides the diver with the advantages of mobility and horizontal range far beyond the reach of an umbilical hose attached to surface-supplied diving equipment (SSDE). Scuba divers engaged in armed forces covert operations may be referred to as frogmen, combat divers or attack swimmers.  - Technical diving (also referred to as tec diving or tech diving) is scuba diving that exceeds the agency-specified limits of recreational diving for non-professional purposes. Technical diving may expose the diver to hazards beyond those normally associated with recreational diving, and to greater risk of serious injury or death. The risk may be reduced by appropriate skills, knowledge and experience, and by using suitable equipment and procedures. The skills may be developed through appropriate specialised training and experience. The equipment often involves breathing gases other than air or standard nitrox mixtures, and multiple gas sources.  - Nitrox is used to a lesser extent in surface-supplied diving, as these advantages are reduced by the more complex logistical requirements for nitrox compared to the use of simple low-pressure compressors for breathing gas supply. Nitrox can also be used in hyperbaric treatment of decompression illness, usually at pressures where pure oxygen would be hazardous. Nitrox is not a safer gas than compressed air in all respects; although its use can reduce the risk of decompression sickness, it increases the risk of oxygen toxicity and fire.  - Recreational diving or sport diving is a type of diving that uses SCUBA equipment for the purpose of leisure and enjoyment . In some diving circles , the term `` recreational diving '' is used in contradistinction to `` technical diving '' , a riskier and more demanding application of the sport which requires greater levels of training , experience and equipment .  - A breathing gas is a mixture of gaseous chemical elements and compounds used for respiration. Air is the most common, and only natural, breathing gas - but a range of pure gases or mixtures of gases are used in breathing equipment and enclosed habitats such as scuba equipment, surface supplied diving equipment, recompression chambers, submarines, space suits, spacecraft, medical life support and first aid equipment, high-altitude mountaineering and anaesthetic machines.
