input: During his twelve-day educational trip to Tunis in April 1914 Klee produced with Macke and Moilliet watercolor paintings, which implement the strong light and color stimulus of the North African countryside in the fashion of Paul Cezanne and Robert Delaunays' cubistic form concepts. The aim was not to imitate nature, but to create compositions analogous to nature's formative principle, as in the works In den Hausern von Saint-Germain (In the Houses of Saint-Germain) and Strassencafe (Streetcafe). Klee conveyed the scenery in a grid, so that it dissolves into colored harmony. He also created abstract works in that period such as Abstract and Farbige Kreise durch Farbbander verbunden (Colored Circles Tied Through Inked Ribbons). He never abandoned the object; a permanent segregation never took place. It took over ten years that Klee worked on experiments and analysis of the color, resulting to an independent artificial work, whereby his design ideas were based on the colorful oriental world. Fohn im Marc'schen Garten (Foehn at Marc's Garden) was made after the Turin trip. It indicates the relations between color and the stimulus of Macke and Delaunay. Although elements of the garden are clearly visible, a further steering towards abstraction is noticeable. In his diary Klee wrote the following note at that time: In the large molding pit are lying ruins, on which one partially hangs. They provide the material for the abstraction. [...] The terrible the world, the abstract the art, while a happy world produces secularistic art. Under the impression of his military service he created the painting Trauerblumen (Velvetbells) in 1917, which, with its graphical signs, vegetal and phantastic shapes, is a forerunner of his future works, harmonically combining graphic, color and object. For the first time birds appear in the pictures, such as in Blumenmythos (Flower Myth) from 1918, mirroring the flying and falling planes he saw in Gersthofen, and the photographed plane crashes. In the 1918 watercolor painting Einst dem Grau der Nacht enttaucht, a compositional implemented poem, possible written by Klee, he incorporated letters in small, in terms of color separated squares, cutting off the first verse from the second one with silver paper. At the top of the cardboard, which carries the picture, the verses are inscribed in manuscript form. Here, Klee did not lean on Delaunay's colors, but on Marc's, although the picture content of both painters does not correspond with each other. Herwarth Walden, Klee's art dealer, saw in them a "Wachablosung" (changing of the guard) of his art. Since 1919 he often used oil colors, with which he combined watercolors and colored pencil. The Villa R (Kunstmuseum Basel) from 1919 unites visible realities such as sun, moon, mountains, trees and architectures, as well as surreal pledges and sentiment readings.

input: In early July 2007, Vitter's phone number was included in a published list of phone records of Pamela Martin and Associates, a company owned and run by Deborah Jeane Palfrey, also known as the "D.C. Madam", who was convicted by the U.S. government for running a prostitution service. Hustler identified the phone number and contacted Vitter's office to ask about his connection to Palfrey. The following day, Vitter issued a written statement in which he took responsibility for his "sin" and asked for forgiveness. On July 16, 2007, after a week of self-imposed seclusion, Vitter emerged and called a news conference. As his wife stood next to him, Vitter asked the public for forgiveness. Following Vitter's remarks, his wife Wendy Vitter spoke, but both refused to answer any questions. While the Louisiana state Republican Party offered guarded support, national Republicans offered forgiveness. The Nation predicted that the Republican Party would be in a "forgiving mood", because if he were to resign, Governor of Louisiana Kathleen Blanco, a Democrat, would likely appoint a Democrat to take Vitter's place until a special election could be held, thus increasing Democratic control over the US Senate. On September 8, 2015, reporter Derek Myers was fired from WVLA-TV after asking Vitter, who was running for governor, about allegations that the senator had frequented prostitutes. After Myers' question, Myers said an unnamed coworker overheard a conversation about the Vitter campaign's ad dollars at the station, possibly with a threat from the campaign to pull the ads. Democrat John Bel Edwards released an ad about the prostitution scandal two weeks before the run-off election and went on to an upset victory, winning by more than 12%.

input: Most ethnic Ukrainians live in Ukraine, where they make up over three-quarters of the population. The largest population of ethnic Ukrainians outside of Ukraine lives in Russia where about 1.9 million Russian citizens consider themselves ethnic Ukrainians, while millions of others (primarily in southern Russia and Siberia) have some Ukrainian ancestry. The inhabitants of the Kuban, for example, have vacillated among three identities: Ukrainian, Russian (an identity supported by the Soviet regime), and "Cossack". Approximately 800,000 people of Ukrainian ancestry live in the Russian Far East in an area known historically as "Green Ukraine". According to some previous assumptions, an estimated number of almost 2.4 million people of Ukrainian origin live in North America (1,359,655 in Canada and 1,028,492 in the United States). Large numbers of Ukrainians live in Brazil (600,000), Kazakhstan (338,022), Moldova (325,235), Argentina (305,000), Germany (272,000), Italy (234,354), Belarus (225,734), Uzbekistan (124,602), the Czech Republic (110,245), Spain (90,530-100,000) and Romania (51,703-200,000). There are also large Ukrainian communities in such countries as Latvia, Portugal, France, Australia, Paraguay, the UK, Israel, Slovakia, Kyrgyzstan, Austria, Uruguay and the former Yugoslavia. Generally, the Ukrainian diaspora is present in more than one hundred and twenty countries of the world. The number of Ukrainians in Poland amounted to some 51,000 people in 2011 (according to Polish Census). Since 2014, the country has experienced a large increase in immigration from Ukraine. More recent data put the number of Ukrainian workers at 1.2 - 1.3 million in 2016. In the last decades of the 19th century, many Ukrainians were forced by the Tsarist autocracy to move to the Asian regions of Russia, while many of their counterpart Slavs under Austro-Hungarian rule emigrated to the New World seeking work and better economic opportunities. Today, large ethnic Ukrainian minorities reside in Russia, Canada, the United States, Brazil, Kazakhstan, Italy and Argentina. According to some sources, around 20 million people outside Ukraine identify as having Ukrainian ethnicity, however the official data of the respective countries calculated together doesn't show more than 10 million. Ukrainians have one of the largest diasporas in the world.
