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.
The Mark-8 is a microcomputer design from 1974, based on the Intel 8008 CPU (which was the world's first 8-bit microprocessor).
 The Mark-8 was designed by graduate student Jonathan Titus and announced as a 'loose kit' in the July 1974 issue of "Radio-Electronics" magazine.
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.
The Grundy NewBrain was a microcomputer sold in the early 1980s by Grundy Business Systems Ltd of Teddington and Cambridge, England.
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.
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.
The EDUC-8, pronounced "educate", was an early microcomputer kit published by Electronics Australia in a series of articles starting in August 1974 and continuing to August 1975.
 Electronics Australia initially believed that it was the first such kit, but later discovered that Radio-Electronics had just beaten it with their Mark-8 by one month.
 However, Electronics Australia staff believed that their TTL design was superior to the Mark-8, as it did not require the purchase of an expensive microprocessor chip.
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.
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.
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.
