Contemporary folk music refers to a wide variety of genres that emerged in the mid 20th century and afterwards which were associated with traditional folk music.
 Starting in the mid-20th century a new form of popular folk music evolved from traditional folk music.
 This process and period is called the (second) folk revival and reached a zenith in the 1960s.
 The most common name for this new form of music is also "folk music", but is often called "contemporary folk music" or "folk revival music" to make the distinction.
 The transition was somewhat centered in the US and is also called the American folk music revival.
 Fusion genres such as folk rock, folktronica, and others also evolved within this phenomenon.
 While contemporary folk music is a genre generally distinct from traditional folk music, it often shares the same English name, performers and venues as traditional folk music; even individual songs may be a blend of the two.
Folk Den is a folk music website founded in 1995 by Roger McGuinn, former front man of The Byrds.
 Hosted at the University of North Carolina at Chapel Hill's ibiblio, the site is intended to preserve and promote folk music and offers a new folk song on a monthly basis.
 Each posting provides an MP3 of a traditional folk song along with a descriptive paragraph, lyrics, guitar chords and related images.
 The site has received positive reviews from "The New York Times", the Discovery Channel, and CNET.
Because of their long, persistent association with humans, cockroaches are frequently referred to in art, literature, folk tales and theater and film.
 In Western culture, cockroaches are often depicted as vile and dirty pests.
 Their size, long antennae, shiny appearance and spiny legs make them disgusting to many humans, sometimes even to the point of phobic responses.
 This is borne out in many depictions of cockroaches, from political versions of the song La Cucaracha where political opponents are compared to cockroaches, through the 1982 movie Creepshow and TV shows such as the X-files, to the Hutu extremists' reference to the Tutsi minority as cockroaches during the Rwandan Genocide in 1994 and the controversial cartoons published in the "Iran weekly magazine" in 1996 which implied a comparison between Iranian Azeris and cockroaches.
Min'yō (民謡 ) is a genre of traditional Japanese music.
 The term is a translation of the German word "Volkslied" (folk song) and has only been in use since the twentieth century.
 Japanese traditional designations referring to more or less the same genre include "inaka bushi" ("country song") "inaka buri" ("country tune"), "hina uta" ("rural song") and the like, but for most of the people who sang such songs they were simply "uta" (song).
 The term min'yō is now sometimes also used to refer to traditional songs of other countries, though a preceding adjective is needed: Furansu min'yō = French folk song; for this reason, many sources in Japanese also feel the need to preface the term with "Nihon": Nihon min'yō = Japanese [traditional] folk song.
Western law refers to the legal traditions of Western culture.
 Western culture has an idea of the importance of law which has its roots in both Roman law and canon law.
 As Western culture has a Graeco-Roman Classical and Renaissance cultural influence, so does its legal systems.
Throughout its history, the United Kingdom has been a major exporter and source of musical innovation, drawing its cultural basis from the history of the United Kingdom, from church music, Western culture and the ancient and traditional folk music and instrumentation of England, Scotland, Ireland and Wales.
In addition to the archetypical mad scientist, western culture depicts scientists and engineers who go above and beyond the regular demands of their professions to use their skills and knowledge for the betterment of others, often at great personal risk.
 In this list of fictional scientists and engineers, an annotated alphabetical overview is given of some of the best-known beings in this category.
