Sisterhood Is Forever: The Women's Anthology for a New Millennium is a 2003 anthology of feminist writings edited by Robin Morgan.
 "Sisterhood Is Forever" has over fifty women contributing sixty original essays written specifically for it.
 "Sisterhood is Forever" is the follow up to "Sisterhood Is Global", which itself is the follow up to "Sisterhood is Powerful".
 "Sisterhood Is Forever" shows the reader feminism's emphases and accomplishments as of 2003.
 The essayists are a diverse group, with varying ages and backgrounds.
 Essays range in tone from scholarly to narrative and provide both conservative and liberal view points.
 The focus is on feminism in the United States.
 The book addresses why feminism is still needed in the 21st century, providing "alarming" statistics about the status of women in the United States in Morgan's introduction.
The Forever Trap is an exclusive to audio "Doctor Who" story, produced as part of BBC Books' New Series Adventures line, and the second entry in the series to be produced.
 Read by Catherine Tate, it is the second non-televised "Doctor Who" adventure to feature the companion Donna Noble.
 It was released on CD on 9 October 2008.
Platoon 1107 is an American patriotic punk rock music band that primarily plays Heavy metal music influenced hardcore punk and skate punk, and at times crossover.
 This project was started in California in 2012 by a United States Marine Corps veteran, Jimmy Sisco, who writes and plays all the instruments on their recordings.
 The project's first two releases, with Thumper Punk Records and Veritas Vinyl, "We Glory in the Title" (a studio album), and an extended play, "Live Free or Die", were released on the same day in 2012.
 The second extended play, "Marine Forever...Forever Marine", was first self-released in December 2013.
 The project did a split-EP, with The Cants earlier the same year.
 In late 2016 the band issued four EP's in 5 weeks via Thumper Punk Records: "The Tourettes EP, The Straight Edge EP, Marine Forever...Forever Marine," and the "Alive I" live album, which was recorded at Angel City in Bellflower, California in 2014.
The Draconians are an extraterrestrial race.
 They were featured in the British science fiction television series "Doctor Who".
 Their only television appearance to date was in the 1973 serial "Frontier in Space".
 Unlike many "monster" races in "Doctor Who", the Draconians were articulate and portrayed as having a sophisticated and advanced culture like feudal Japan.
 In later interviews, Jon Pertwee cited the Draconians as his favourite of all the monsters he had encountered during his time as the Doctor.
 They were part of the alliance to trap the doctor in the pandorica.
The phrase "Horizons of Expectation" is a term fundamental to German academic Hans Robert Jauss's Reception theory.
 The concept is a component of his theory of literary history where his intention is to minimise the gulf between the schools of literature and history which have previously relegated the reader to play only a minor role in the interpretation of literature.
 Specifically, it is the structure by which a person comprehends, decodes and appraises any text based on cultural codes and conventions particular to their time in history.
 These horizons are therefore historically flexible meaning readers may interpret and value a text differently from a previous generation.
 It emphasises the reader as an important element in the processing of texts.
 According to Jauss, the reader approaches a text armed with the knowledge and experience gained from interactions with other texts.
 These earlier texts arouse familiarity for the reader based on expectations and rules of genre and style.
 Jauss describes it this way, 'a literary work is not an object which stands by itself and which offers the same face to each reader in each period'.
 Thus reading is not an 'autonomous, free and individual' experience but rather a collection of mutual concepts fitting a period or a people.
In American football, a trap play, or trap run, is a run consisting of a defender on the line of scrimmage (either a defensive tackle or defensive end) getting trap blocked by an offensive lineman or back from the opposite (other side of the center) side of the ball.
 The play is known as a "trap" because the strong side offensive lineman will "block down" on a linebacker, seemingly leaving a defensive lineman unblocked.
 As the defensive lineman comes through the seemingly open gap/hole, he is "trapped" by the weak side (also known as backside) guard who blocks the defensive lineman's blindside.
 Occasionally, a trap block will come from a tight end.
 Trap blocks by tight ends are known as "CRACK BACK" blocks.

A Chinese finger trap (also known as a Chinese finger puzzle, Chinese thumb cuff, Chinese handcuffs and similar variants) is a gag toy used to play a practical joke on unsuspecting children and adults.
 The finger trap is a simple puzzle that traps the victim's fingers (often the index fingers) in both ends of a small cylinder woven from bamboo.
 The victim of the joke must push their finger farther inside the trap for it to loosen.
