Vienna, Austria in the context of "Wienfluss"

A constitutional referendum regarding the Prince's powers was held in Liechtenstein on 14 March 2003. The referendum had two questions: a "Princely Initiative" and a "Constitution Peace Initiative". The first question passed with 64.32% in favour and the second question was rejected by 83.44% of voters.

The Princely Initiative asked voters whether to approve an extension of the power of the Prince to dismiss the government, nominate judges and veto legislation. The Constitution Peace Initiative asked voters whether to approve or disapprove of constitutional modifications, including modifications which would have restricted the Prince's powers. The BBC stated that the referendum in effect made Liechtenstein into an "absolute monarchy". In December 2002 the Venice commission of the Council of Europe published a comprehensive report analysing the amendments, opining that they were not compatible with the European standard of democracy. Prince Hans-Adam II had threatened to leave the country and live in exile in Vienna, Austria if the voters had chosen to restrict his powers.

William Tecumseh Sherman Fitch III (born 1963) is an American evolutionary biologist and cognitive scientist at the University of Vienna (Vienna, Austria) where he is co-founder of the Department of Cognitive Biology. He was elected a Member of the National Academy of Sciences in 2025.

Fitch studies the biology and evolution of cognition and communication in humans and other animals, and in particular the evolution of speech, language and music. His work concentrates on comparative approaches as advocated by Charles Darwin (i.e., the study of homologous and analogous structures and processes in a wide range of species).

The Second Viennese School (German: Zweite Wiener Schule, Neue Wiener Schule) was a group of composers that comprised Arnold Schoenberg and his pupils, particularly Alban Berg and Anton Webern, and close associates in early 20th-century Vienna. Their music was initially characterized by late-Romantic expanded tonality and later, a totally chromatic expressionism without a firm tonal centre, often referred to as atonality; and later still, Schoenberg's serial twelve-tone technique. Using this technique when composing, Schoenberg employed all 12 tones present in Western music's chromatic scale when forming a melody, this melody being the "prime series". This method would later be enhanced in compositions by Schoenberg and his followers through permutations such as "retrogrades", "inversions", "transformations" etc. Later, composers such as Pierre Boulez drew influence from Schoenberg's technique in furthering serialization; serializing not only pitch but rhythm, articulation, and dynamics as well. Theodor Adorno said that the twelve-tone method, when it had evolved into maturity, was a "veritable message in a bottle", addressed to an unknown and uncertain future. Though this common development took place, it neither followed a common time-line nor a cooperative path. Likewise, it was not a direct result of Schoenberg's teaching—which, as his various published textbooks demonstrate, was highly traditional and conservative. Schoenberg's textbooks also reveal that the Second Viennese School spawned not from the development of his serial method, but rather from the influence of his creative example.

Peter Michael Blau (February 7, 1918 – March 12, 2002) was an Austrian and American sociologist and theorist. Born in Vienna, Austria, he immigrated to the United States in 1939. He completed his PhD doctoral thesis with Robert K. Merton at Columbia University in 1952, laying an early theory for the dynamics of bureaucracy. The next year, he was offered a professorship at the University of Chicago, where he taught from 1953 to 1970. He also taught as Pitt Professor at Cambridge University in Great Britain, as a senior fellow at King's College, and as a Distinguished Honorary professor at Tianjin Academy of Social Sciences which he helped to establish. In 1970 he returned to Columbia University, where he was awarded the lifetime position of professor emeritus. From 1988 to 2000 he taught as the Robert Broughton Distinguished Research Professor at University of North Carolina, Chapel Hill in the same department as his wife, Judith Blau, while continuing to commute to New York to meet with graduate students and colleagues.

His sociological specialty was in organizational and social structures. He formulated theories relating to many aspects of social phenomena, including upward mobility, occupational opportunity, and heterogeneity. From each of his theories, he deduced an hypothesis which he would test against large scale empirical research. He was one of the first sociological theorists to use high level statistics to develop sociology as a scientific discipline using macro-level empirical data to gird theory. He also produced theories on how population structures can influence human behavior.
