Question: What type of profession does Ivan Fesenko and Valery Goppa have in common?
Context: In mathematics, Fesenko groups are certain subgroups of the wild automorphism groups of local fields of positive characteristic (i.e. the Nottingham group), studied by Ivan Fesenko (). Ivan Fesenko (Russian: Иван Борисович Фесенко ; born 1962) is a mathematician working in number theory and other areas of modern mathematics. Valery Denisovich Goppa (Russian: Вале́рий Дени́сович Го́ппа ; born 1939) is a Soviet and Russian mathematician. In mathematics and computer science, the binary Goppa code is an error-correcting code that belongs to the class of general Goppa codes originally described by Valerii Denisovich Goppa, but the binary structure gives it several mathematical advantages over non-binary variants, also providing a better fit for common usage in computers and telecommunication.  Binary Goppa codes have interesting properties suitable for cryptography in McEliece-like cryptosystems and similar setups. A convention, in the sense of a meeting, is a gathering of individuals who meet at an arranged place and time in order to discuss or engage in some common interest.  The most common conventions are based upon industry, profession, and fandom.  Trade conventions typically focus on a particular industry or industry segment, and feature keynote speakers, vendor displays, and other information and activities of interest to the event organizers and attendees.  Professional conventions focus on issues of concern to the profession and advancements in the profession.  Such conventions are generally organized by societies or communities dedicated to promotion of the topic of interest.  Fan conventions usually feature displays, shows, and sales based on pop culture and guest celebrities.  Science fiction conventions traditionally partake of the nature of both professional conventions and fan conventions, with the balance varying from one to another.  Conventions also exist for various hobbies, such as gaming or model railroads. Professional Identification is a type of social identification and is the sense of oneness individuals have with a profession (e.g. law, medicine) and the degree to which individuals define themselves as profession members.  Professional identity consists of the individual's alignment of roles, responsibilities, values, and ethical standards to be consistent with practices accepted by their specific profession. Prior to the Ivan Allen Jr.  Prize for Social Courage, the Georgia Institute of Technology's Ivan Allen College of Liberal Arts had awarded the Ivan Allen Jr.  Prize for Progress & Service.  Awarded annually from 2001-2010, the Prize honored individuals who had contributed to the progress of American civilization through his or her service to a field or profession associated with the academic disciplines taught in the Ivan Allen College. A stereotype is a generalized idea or image about a particular person or thing that is often oversimplified and offensive.  Stereotypes are victim of prejudice when negative portrayals of a group are untrue of individual members.  Nursing has been stereotyped throughout the history of the profession.  A common misconception is that all nurses are female; this has led to the stereotype of male nurses as effeminate.  These generalized ideas of the nursing profession have formed a skewed image of nurses in the media.  The image of a nurse projected by the media is typically of a young white single female being over-sexualized as well as diminished intellectually; this idea is then portrayed in get-well cards, television shows and novels.  The over-sexualized nurse is commonly referred to as a naughty nurse and is shown as a sex symbol or nymphomaniac. Along with these common stereotypes, studies have identified several other popular images used in media such as handmaiden, angel, torturer, homosexual male, alcoholic, buffoon and woman in white.  Common stereotypes of nursing and portrayal of these misconceptions have fueled a discussion on the effects they have on the profession, harmful or good. Vedma (The Power of Fear) (Russian: Ведьма) is a 2006 Russian gothic horror film directed by Oleg Fesenko and starring Valery Nikolaev in the lead. In mathematics, an algebraic geometric code (AG-code), otherwise known as a Goppa code, is a general type of linear code constructed by using an algebraic curve formula_1 over a finite field formula_2.  Such codes were introduced by Valerii Denisovich Goppa.  In particular cases, they can have interesting extremal properties.  They should not be confused with Binary Goppa codes that are used, for instance, in the McEliece cryptosystem.
