The McPolin Farmstead is a historic farm north of Park City, Utah, United States.
 It has buildings constructed c. 1921 and later, including a large "improvement era" dairy barn, approximately 100 x in footprint.
 It was purchased by, and is owned by, the nearby city of Park City, Utah.
 It was listed on the National Register of Historic Places in 2003.
The Improvement Era (often shortened to "The Era") was an official magazine of The Church of Jesus Christ of Latter-day Saints (LDS Church) between 1897 and 1970.
Robinson Ekspeditionen 2008 (also known as Robinson: Fans vs. Paradise) was the eleventh season of the Danish versions of the Swedish show "Expedition Robinson".
 This season premiered on September 1, 2008 and aired until November 24, 2008.
 The main twist this season was that every contestant was either a fan of Robinson or was a former contestant on the show "Paradise Hotel".
 The fan tribe was called "Tenga", while the Paradise tribe was called "Sembilang".
 There were many additional twists this season, the first taking place in episode 1 when all of the contestants were made to take part in an elimination challenge.
 Mirja Østergaard lost the challenge and was immediately eliminated.
 The next twist took place in episode 2 when Jan Novaa, who had been voted out in episode one, returned to the game.
 The next twist took place in episode 3 when Emil Debski swapped tribes in order to even up the tribe numbers.
 In episode 4 a larger tribal swap took place in which Jan Novaa, Mads Jensen, and Michelle Jensen swapped from the Sembilang tribe to the Tenga tribe and Emil Debski, Hilde Austad, Martin Persson, Chiro "Sido" Kiarie swapped from the Tenga tribe to the Sembilang tribe.
 The next twist came in episode 5 when jokers Laila Neilsen and Nick Zitouni entered the game with Laila joining the Sembilang tribe and Nick joining the Tenga tribe.
 In episode 6 an individual challenge took place in which the winner would be allowed to eliminate a player from the opposing tribe.
 Haider Mohamad won the challenge and chose to eliminate Sheila Nymann.
 Immediately following the merge in episode 7, Haider won the same type of challenge and chose to eliminate Karina Strunge from the game.
 The next twist came in episode 10 when contestant Hilde Austad used the "Talisman" she had to void any votes cast against her in tribal council.
 This led to the elimination of Laila Neilsen who had the second most votes.
 When it came time for the final four, the remaining contestants competed in two challenges.
 The winners of these challenges would earn the right to eliminate one of the losers.
 Emil won the first challenge and chose to eliminate Martin and Daniela won the second challenge and chose to eliminate Emil.
 Ultimately, it was Daniela Hansen from Paradise Hotel 2006 who won the season over Robinson fan Hilde Austad by a tiebreaking cointoss after the jury vote ended in a 4-4 tie.
Twist is an online teen-focused website and was a monthly print teen magazine.

 The first issue was released in 1997.
Evidences and Reconciliations: Aids to Faith in a Modern Day is a Mormon apologetic book by John A. Widtsoe.
 Originally published in 1943 by Bookcraft, the book was a reprint of Widtsoe's column of the same name, which regularly appeared in "Improvement Era", an official magazine of The Church of Jesus Christ of Latter-day Saints (LDS Church).
 Widtsoe was a scientist and an apostle of the LDS Church.
New Era is an official magazine of The Church of Jesus Christ of Latter-day Saints (LDS Church).
 First published in January 1971 along with the "Ensign" and the "Friend", the "New Era's" intended audience has always been the church's youth.
 The magazine replaced the similarly themed "The Improvement Era", a periodical published from 1897 to 1970.
The Ensign of The Church of Jesus Christ of Latter-day Saints, commonly shortened to Ensign , is an official periodical of The Church of Jesus Christ of Latter-day Saints (LDS Church).
 The magazine was first issued in January 1971 along with the correlated "New Era" (for youth) and the "Friend" (for children), all of which replaced the older church publications "Improvement Era", "Relief Society Magazine", "The Instructor", and the "Millennial Star".
 Unlike some of its predecessors, the "Ensign" contains no advertisements.
Abraham H. Cannon became editor when the magazine was purchased by the Cannon Publishing Company in 1892.
 With the death of Cannon in July 1896, "The Contributor" ceased publication a few months later and was not immediately replaced.
 The "Young Woman's Journal" had begun publication in 1889 and it replaced "The Contributor" for the YLMIA in all but name.
 However, to provide an official replacement for "The Contributor" that would cater to both young men and young women, the YMMIA and the YLMIA began publication of the "Improvement Era" in 1897.
The 1754 Horeki River Improvement Incident was an incident in which the Tokugawa Shogunate maliciously ordered the Satsuma han to carry out difficult river improvement works.
 Rivers which caused frequent floods included the Kiso, Nagara and Ibi Rivers near Nagoya in the Horeki age.
 This order ultimately resulted in 51 Satsuma samurai committing suicide, 33 persons dying from disease and the responsible karō, Hirata Yukie, committing seppuku.
 The river improvement project was finally completed in the Meiji era.
 The incident is also called the Horeki Age River Improvement Incident and the Nobi Plain River Improvement Incident.
