Valentine Browne, 1st Earl of Kenmare (January 1754 – 3 October 1812) was the Seventh Baronet Browne.
 He was created First Baron Castlerosse and First Viscount Kenmare on 12 February 1798, with the earlier peerages not being recognised.
 He was created First Earl of Kenmare on 3 January 1801.
Baron Trevor is a title that has been created three times.
 It was created first in 1662 in the Peerage of Ireland along with the viscountcy of Dungannon.
 For information on this creation, which became extinct in 1706, see Viscount Dungannon.
CJ the DJ is an Australian animated TV series created first broadcast on ABC3.
 The show was created by Mark Gravas of "Yakkity Yak" fame and writer Stu Connolly.
Chatelaine is an English-language Canadian magazine of women's lifestyles and the number one magazine in Canada in paid circulation.
 Both "Chatelaine" and its French-language version, "Châtelaine", are published monthly by Rogers Media, a division of Rogers Communications.
 It was first published in March 1928 by Maclean Publishing.
 Due to falling print ad revenues, "Chatelaine" reduced its publication frequency to 6 times a year beginning in 2017.
 Other Rogers Media publications are also to either reduce their publication frequency or become digital only publications.
 Rogers Media also announced that it intends to divest itself of its French-language publications, including "Châtelaine".
Thomas Browne, 6th Baronet & 4th Viscount Kenmare (April 1726 – 11 September 1795) was an Irish landowner and politician.
 He was probably born at Killarney, County Kerry, the second of four children of Valentine Browne, fifth Baronet, third Viscount Kenmare (1695–1736), one of the few remaining great Roman Catholic landowners in Ireland, and his first wife, Honoria Butler (?
-1730).
 Thomas Browne's great-grandfather, Sir Valentine Browne, third Baronet, had been created first Viscount Kenmare by James II in March 1689.
 This was an Irish peerage created after the removal of James II from the English throne, but during the period when James was de facto king of Ireland, before the conquest of Ireland by William III.
 The first and second viscounts had fought for James II but seem never to have been formally attainted under William.
 Consequently, the peerage remained on the Irish patent roll in a constitutionally ambiguous position, but was not formally recognised by the Protestant political establishment.
The United States Peace Index (USPI) is a measurement of American States and cities by their peacefulness.
 Created by the Institute for Economics and Peace, the creators of the Global Peace Index, it is said to be the first in a series of National sub-divisions by their peacefulness.
 The USPI was created first due to plentiful data and a large amount of diversity between states for level of peace.
 The United States ranked 88/158 on the Global Peace index for 2012.
 The U.S. index was released on 6 April 2011, at 00:01 Eastern Time and the second edition released on 24 April 2012.
Viscount Powerscourt ( ) is a title that has been created three times in the Peerage of Ireland, each time for members of the Wingfield family.
 It was created first in 1618 for the Chief Governor of Ireland, Richard Wingfield.
 However, this creation became extinct on his death in 1634.
 It was created a second time in 1665 for Folliott Wingfield.
 He was the great-great-grandson of George Wingfield, uncle of the first Viscount of the 1618 creation.
 However, the 1665 creation also became extinct on the death of its first holder in 1717.
Baron Talbot is a title that has been created twice.
 The title was created first in the Peerage of England.
 On 5 June 1331, Sir Gilbert Talbot was summoned to Parliament, by which he was held to have become Baron Talbot.
Transition scenarios are descriptions of future states which combine a future image with an account of the changes that would need to occur to reach that future.
 These two elements are often created in a two-step process where the future image is created first (envisioning) followed by an exploration of the alternative pathways available to reach the future goal (backcasting).
 Both these processes can use participatory techniques (Raskin et al., 2002) where participants of varying backgrounds and interests are provided with an open and supportive group environment to discuss different contributing elements and actions.
Arthur's Magazine (1844–1846) was an American literary periodical published in Philadelphia in the 19th century.
 Edited by T.S. Arthur, it featured work by Edgar A. Poe, J.H. Ingraham, Sarah Josepha Hale, Thomas G. Spear, and others.
 In May 1846 it was merged into "Godey's Lady's Book".
