Background: Winchell was born Paul Wilchinsky in New York City on December 21, 1922, to Solomon Wilchinsky and Clara Fuchs. His father was a tailor; his grandparents were Jewish immigrants from Russian Poland and Austria-Hungary. Winchell's initial ambition was to become a doctor, but the Depression wiped out any chance of his family's ability to afford medical school tuition. At age 13, he contracted polio; while recovering, he happened upon a magazine advertisement offering a ventriloquism kit for ten cents.
Context: Winchell's best-known ventriloquist dummies were Jerry Mahoney and Knucklehead Smiff. Mahoney was carved by Chicago-based figure maker Frank Marshall. Sometime later Winchell had basswood copies of Jerry's head made by a commercial duplicating service. One became the upgraded Jerry Mahoney that is seen primarily throughout Winchell's television career. The television versions of Jerry and Knucklehead also featured Winchell's innovation of actors slipping their hands into the sleeves of the dummies, giving the visual effect of gesturing with their hands while "conversing" with each other. He modified two other copies to create Knucklehead Smiff. The original Marshall Jerry Mahoney and one copy of Knucklehead Smiff are in storage at the Smithsonian Institution. The other two figures are in the collection of illusionist David Copperfield.  Winchell's first show as a ventriloquist was on radio with Jerry Mahoney in 1943. The program was short-lived, however, as he was overshadowed by Edgar Bergen. Winchell also created Ozwald, a character that resembled Humpty Dumpty. The effect was accomplished by painting eyes and a nose on his chin, then adding a "body" covering the rest of his face, and finally electronically turning the camera image upside down. In 1961, Berwin Novelties introduced a home version of the character that included an Oswald body, creative pencils to draw the eyes and nose and a "magic mirror" that automatically turned a reflection upside down.  In 1948, Winchell and Joseph Dunninger were featured on Floor Show on NBC. Recorded via kinescope and replayed on WNBQ-TV in Chicago, Illinois, the 8:30-9 p.m. Central Time show on Thursdays was the station's first mid-week program.  During the 1950s, Winchell hosted children's and adult programs with his figures for NBC Television, and later for syndication. The NBC Saturday morning program, sponsored by Tootsie Roll, featured a clubhouse motif and a theme song co-written by Winchell and his longtime bandleader and on-air sidekick, Milton DeLugg. The theme song was entitled "HOORAY, HOORAH" which featured the secret password "SCOLLY WALLY DOO DOO". An ending song entitled "Friends, Friends, Friends" was sung by the children in the audience. On one episode, The Three Stooges appeared on the show to promote their joint feature film venture, Stop, Look, and Laugh, in late 1959. He made an appearance on Nanny and the Professor (Season 2, Episode 13) as a "mean old man" (a puppeteer who had retired into seclusion after losing his wife in an accident). In 1996, Winchell contracted with figure maker Tim Selberg to construct a more contemporary version of Jerry Mahoney, which Winch described as "Disney-esque". Winchell used the new figure version to pitch a new TV series idea to Michael Eisner. In 2009 Winchell was featured in the comedy documentary I'm No Dummy, directed by Bryan W. Simon.

Problem: Background: Anna Stepanovna Politkovskaya (Russian: Anna Stepanovna Politkovskaia, IPA: ['an:@ sjtjI'pan@vn@ p@ljIt'kofsk@j@]; Ukrainian: Ganna Stepanivna Politkovs'ka ['han:a ste'panjiuna poljit'kousjka]; nee Mazepa [ma'zepa]; 30 August 1958 - 7 October 2006) was a Russian journalist, writer, and human rights activist who reported on political events in Russia, in particular, the Second Chechen War (1999-2005).
Context: Politkovskaya won a number of awards for her work. She used each of these occasions to urge greater concern and responsibility by Western governments that, after the 11 September attacks on the United States, welcomed Putin's contribution to their "War on Terror". She talked to officials, the military and the police and also frequently visited hospitals and refugee camps in Chechnya and in neighbouring Ingushetia to interview those injured and uprooted by the renewed fighting.  In numerous articles critical of the war in Chechnya and the pro-Russian regime there, Politkovskaya described alleged abuses committed by Russian military forces, Chechen rebels, and the Russian-backed administration led by Akhmad Kadyrov and his son Ramzan Kadyrov. She also chronicled human rights abuses and policy failures elsewhere in the North Caucasus. In one characteristic instance in 1999, she not only wrote about the plight of an ethnically-mixed old peoples' home under bombardment in Grozny, but helped to secure the safe evacuation of its elderly inhabitants with the aid of her newspaper and public support. Her articles, many of which form the basis of A Dirty War (2001) and A Small Corner of Hell (2003), depict a conflict that brutalised both Chechen fighters and conscript soldiers in the federal army, and created hell for the civilians caught between them.  As Politkovskaya reported, the order supposedly restored under the Kadyrovs became a regime of endemic torture, abduction, and murder, by either the new Chechen authorities or the various federal forces based in Chechnya. One of her last investigations was into the alleged mass poisoning of Chechen schoolchildren by a strong and unknown chemical substance which incapacitated them for many months.
Question: What were some of the abuses?
Answer:
She also chronicled human rights abuses and policy failures elsewhere in the North Caucasus.
