Hell in a Cell: Hell in a Cell is a professional wrestling cage-based match held in WWE (formerly World Wrestling Federation).  It features a large roofed steel cage structure or "cell" which encloses the ring and ringside area.  While similar to the steel cage match in profile and structure, unlike the steel cage match wherein exiting over the cage results in a win, only executing a pinfall or submission will result in a win.  As in a steel cage match, disqualifications do not apply.  The original Cell was 16 ft high and weighed over two tons but has since been replaced by an amplified version of 20 ft and five tons.  Thirty-six Hell in a Cell matches have taken place in WWE since its inception in October 1997.  The match type spawned its own pay-per-view and later WWE Network event in 2009, WWE Hell in a Cell, which has been held annually in October since.  This event generally features anywhere from one to three Hell in a Cell Matches on the same card.

Ayşe Nur Zarakolu: Ayşe Nur Zarakolu (née Sarısözen) (9 May 1946 – 28 January 2002) was a Turkish author, publisher and human rights advocate.  She was co-founder, with her husband Ragıp Zarakolu, of notable Turkish publishing house Belge and, in the 1980s, became the director of book-distribution company Cemmay, the first woman in the nation to hold such a position.  Zarakolu's publications brought her into frequent conflict with Turkish press laws; in 1997, the "New York Times" identified Zarakolu as "one of the most relentless challengers to Turkey's press laws".  Issues Zarakolu helped publicize in Turkey include the Armenian Genocide and human rights of Kurdish people in Turkey.  Imprisoned multiple times for her publications, she was designated a prisoner of conscience by Amnesty International and her legacy continued to face legal challenge in Turkey after her death.  She has received multiple awards and honors for her work and the Human Rights Association of Turkey (Turkish: "İnsan Hakları Derneği" İHD) bestows the Ayşe Zarakolu Freedom of Thought prize in her honor.

The official charge was "leadership of an armed organisation" and was in conjunction with a series of arrests of pro-Kurdistan intellectuals in Istanbul.

Rumor control center: Rumor control centers are public-service operations designed to help publicize true information (assuming, of course, that there is any such thing) in times of crisis, terrorist attack, natural disaster, or civil disturbance.  A major function is to operate a call center to respond to inquiries from concerned citizens, generally prompted either by rumors or a lack of information about what is happening.  Permanent rumor control centers serve a specific, local population, and have often been set up in response to specific incidents.

Armenian Genocide: The Armenian Genocide (Armenian: Հայոց ցեղասպանություն , "Hayots tseghaspanutyun"), also known as the Armenian Holocaust, was the Ottoman government's systematic extermination of 1.5 million Armenians, mostly Ottoman citizens within the Ottoman Empire and its successor state, the Republic of Turkey.  The starting date is conventionally held to be 24 April 1915, the day that Ottoman authorities rounded up, arrested, and deported 235 to 270 Armenian intellectuals and community leaders from Constantinople to the region of Ankara, the majority of whom were eventually murdered.  The genocide was carried out during and after World War I and implemented in two phases—the wholesale killing of the able-bodied male population through massacre and subjection of army conscripts to forced labour, followed by the deportation of women, children, the elderly, and the infirm on death marches leading to the Syrian Desert.  Driven forward by military escorts, the deportees were deprived of food and water and subjected to periodic robbery, rape, and massacre.  Other indigenous and Christian ethnic groups, such as the Assyrians and the Ottoman Greeks, were similarly targeted for extermination by the Ottoman government in the Assyrian genocide and the Greek genocide, and their treatment is considered by some historians to be part of the same genocidal policy.  Most Armenian diaspora communities around the world came into being as a direct result of the genocide.

He became executive secretary of the National Parks Association in 1919.
