Elvaston, Derbyshire: Elvaston is a small village and civil parish in Derbyshire, England.  The parish also includes two hamlets, Ambaston and Thulston, and a modern housing estate, Boulton Moor.  The population of the civil parish taken at the 2011 Census was 1,801.  Located to the south-east of Derby, Elvaston itself is dominated by Elvaston Castle, a country house which is currently in the ownership of Derbyshire County Council, who plan to lease the site to a private company.  The move has proved controversial, attracting a petition of 60,000 signatures against the proposals collected by the Elvaston Castle Estate Trust, who want to keep the site in public ownership.  At the present time the Castle is rarely open to the public and has been somewhat neglected, while the grounds are open throughout the summer.

AmINext: <nowiki>#</nowiki>AmINext is a social media campaign that was launched on September 5, 2014 by a Canadian Inuit woman named Holly Jarrett in order to call attention to the high rate of missing and murdered Indigenous women in Canada.  Jarrett's hashtag campaign was launched following the release of her Change.org petition in August 2014 calling for a government inquiry into the high rate of missing and murdered Indigenous women.  Social media users participate in the hashtag campaign by posting photographs of themselves holding up signs displaying the hashtag and by including a short message about why they are participating.  The campaign was created in response to the deaths of Loretta Saunders, Jarrett’s cousin, and Tina Fontaine, a 15-year-old Aboriginal girl, among others.  For over a decade, Indigenous activists have called for a government inquiry into the disproportionate rate of violence perpetuated against Indigenous women.  Demand for this investigation was reignited following the death of Fontaine.  The #AmINext campaign calls on the conservative government, then headed by Stephen Harper, to acknowledge the pattern of violence.  The campaign received widespread coverage across Canada following its launch due to simultaneous news reports releasing details of the Fontaine case.  On September 11, 2014, the BBC aired a segment on the campaign which resulted in international coverage.  As of March 2016, the petition on Change.org has received over 300,000 signatures.

Nominating petition: A nominating petition is required in some jurisdictions, particularly in the United States of America, in order for an independent or non-major-party candidate to gain ballot access.  A certain number of valid signatures is typically prescribed by statute in order for the candidate to get on the ballot.  Thus, it is necessary to get an overage of "raw" signatures (perhaps twice as many as the statutory requirement) in order to assure getting on the ballot, as some signatures may be illegible, incomplete, of individuals not registered to vote, or not in the candidate's electoral district, or otherwise invalid.  Paid petitioners sometimes assist in gathering signatures.
