Context paragraphs:

Nurse stereotypes: 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.

Alphaville (band): Alphaville is a German synthpop/new wave band which gained popularity in the 1980s.  The founding members were lead singer Marian Gold (real name: Hartwig Schierbaum, born 26 May 1954 in Herford), Bernhard Lloyd (real name: Bernhard Gössling, born 2 June 1960 in Enger), and Frank Mertens (real name: Frank Sorgatz, born 26 October 1961 in Enger).  The band was at first named "Forever Young" before being changed to "Alphaville".  They achieved chart success with the singles "Big in Japan", "Sounds Like a Melody", "Jet Set", "Dance With Me", "Jerusalem", "Romeos" and "Forever Young".

Mutillidae: The Mutillidae are a family of more than 3,000 species of wasps whose wingless females resemble large, hairy ants.  Their common name velvet ant refers to their dense pile of hair, which most often is bright scarlet or orange, but may also be black, white, silver, or gold.  Black and white specimens are sometimes known as panda ants due to their hair coloration resembling that of the giant panda.  Their bright colors serve as aposematic signals.  They are known for their extremely painful stings, (the sting of the species "Dasymultila klugii" rated a 3 on the Schmidt pain index and lasts up to 30 minutes), hence the common name cow killer or cow ant.  However, mutillids are not aggressive and sting only in defense.  In addition, the actual toxicity of their venom is much lower than that of honey bees or harvester ants.  Unlike true ants, they are solitary, and lack complex social systems.

I Die for You Today: I Die for You Today is the 22nd single overall from Alphaville, and the first single from Alphaville's 2010 album "Catching Rays on Giant".  The original lyrics for the song were written by The Outsider, a long-time fan of the band, and published on the band's official mailing list in 2001.  Marian Gold later re-worked the lyrics for the song.

Professional identification: 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.

Convention (meeting): 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.
