Question: Panic! at the Disco and Matt Willis, are which type of specific group?
Context: Violence against women (VAW), also known as gender-based violence, is, collectively, violent acts that are primarily or exclusively committed against women.  Sometimes considered a hate crime, this type of violence targets a specific group with the victim's gender as a primary motive.  This type of violence is gender-based, meaning that the acts of violence are committed against women expressly because they are women.  The UN Declaration on the Elimination of Violence Against Women states that: "Don't Let It Go to Waste" is the third single from Matt Willis, released on 11 December 2006.  Several days before the single's release, Willis was announced the winner of the reality TV-show "I'm a Celebrity, Get Me Out Of Here!" .  A show Willis admitted going on purely to boost his music career. In mathematics, more specifically in the area of abstract algebra known as Galois theory, the Galois group of a certain type of field extension is a specific group associated with the field extension.  The study of field extensions and their relationship to the polynomials that give rise to them via Galois groups is called Galois theory, so named in honor of Évariste Galois who first discovered them. "Hey Kid" is the second official single from Matt Willis, released on August 14, 2006.  It is taken from Willis's debut solo album "Don't Let It Go to Waste".  "Hey Kid" also appears in the 2006 teen film "John Tucker Must Die" and the action packed teen film "Alex Rider:Stormbreaker", and therefore will be on both the films soundtracks. Mathew James "Matt" Willis (born 8 May 1983), also previously known as Mattie Jay, is an English singer-songwriter, television presenter and actor, best known as the bassist and one of the vocalists of the pop punk band, Busted.  Willis released his debut solo album "Don't Let It Go to Waste" on 20 November 2006, which included three top 20 singles. "Up All Night" is Matt Willis's debut single as a solo artist.  It was released as a single on 22 May 2006 and appears on his debut album, "Don't Let It Go to Waste".  Its style marks a move towards more rock-influenced music than the songs Willis released when performing as part of Busted and could possibly be categorized as stadium pop. Panic!  at the Disco is an American rock band from Las Vegas, Nevada, formed in 2004 and featuring the current lineup of vocalist Brendon Urie, accompanied on tour by bassist Dallon Weekes, guitarist Kenneth Harris and drummer Dan Pawlovich.  Founded by childhood friends Ryan Ross, Spencer Smith, Brent Wilson and Urie, Panic!  at the Disco recorded its first demos while its members were in high school.  Shortly after, the band recorded and released its debut studio album, "A Fever You Can't Sweat Out" (2005).  Popularized by the second single, "I Write Sins Not Tragedies", the album was certified double platinum in the US.  In 2006, founding bassist Brent Wilson was fired from the band during an extensive world tour and subsequently replaced by Jon Walker. The name apophyllite refers to a specific group of phyllosilicates, a class of minerals.  Originally, the group name referred to a specific mineral, but was redefined in 1978 to stand for a class of minerals of similar chemical makeup that comprise a solid solution series, and includes the members fluorapophyllite-(K), fluorapophyllite-(Na), hydroxyapophyllite-(K).  The name apophyllite is derived from the Greek ἀποφυλλίζω "apophylliso," meaning "it flakes off", a reference to this class's tendency to flake apart when heated, due to water loss.  These minerals are typically found as secondary minerals in vesicles in basalt or other volcanic rocks.  A recent change (2008) in the nomenclature system used for this group was approved by the International Mineralogical Association, removing the prefixes from the species names and using suffixes to designate the species.  A subsequent nomenclature change approved by the International Mineralogical Association in 2013 renamed the minerals to include both suffixes and prefixes, as shown above. A training workshop is a type of interactive training where participants carry out a number of training activities rather than passively listen to a lecture or presentation.  Broadly, two types of workshops exist: A general workshop is put on for a mixed audience, and a closed workshop is tailored towards meeting the training needs of a specific group. An ethnic exogroup is a group of people which does not belong to a particular ethnic group.  Many cultures have terms referring to all outsiders, but in practice this often becomes narrowed to the largest outsider group.  In particular, exogroup terms used by minorities in a particular country often become specific to the majority in that country rather than applying to other minorities as well.  Exogroup terms are sometimes considered to be derogatory, depending on the word and the context and manner in which it is used.  They may be distinguished from ethnic or religious slurs in that they do not necessarily designate a specific group, and instead target all who do not belong to a specific group.
