The framers of the US Constitution were influenced by the Constitution of the Republic of the United Provinces, as Federalist No. 20, by James Madison, shows. Such influence appears, however, to have been of a negative nature, as Madison describes the Dutch confederacy as exhibiting "Imbecility in the government; discord among the provinces; foreign influence and indignities; a precarious existence in peace, and peculiar calamities from war." Apart from this, the American Declaration of Independence is similar to the Act of Abjuration, essentially the declaration of independence of the United Provinces, but concrete evidence that the former directly influenced the latter is absent.
The American Declaration of Independence is similar to what?
the Act of Abjuration, essentially the declaration of independence of the United Provinces

Madonna has received acclaim as a role model for businesswomen in her industry, "achieving the kind of financial control that women had long fought for within the industry", and generating over $1.2 billion in sales within the first decade of her career. Professor Colin Barrow from Cranfield School of Management described Madonna as "America's smartest businesswoman ... who has moved to the top of her industry and stayed there by constantly reinventing herself." London Business School academics called her a "dynamic entrepreneur" worth copying; they identified her vision of success, her understanding of the music industry, her ability to recognize her own performance limits (and thus bring in help), her willingness to work hard and her ability to adapt as the keys to her commercial success. Morton wrote that "Madonna is opportunistic, manipulative, and ruthless—somebody who won't stop until she gets what she wants—and that's something you can get at the expense of maybe losing your close ones. But that hardly mattered to her." Hazel Blackmore and Rafael Fernández de Castro in the book ¿Qué es Estados Unidos? from the Fondo de Cultura Económica, noted: "Madonna has been undoubtedly the most important woman in the history of popular music and a great businesswoman in herself; creating fashion, breaking taboos and provoking controversies."
Who called Madonna a dynamic entrepreneur?
London Business School academics

In tumbling, athletes perform an explosive series of flips and twists down a sprung tumbling track. Scoring is similar to trampolining. Tumbling was originally contested as one of the events in Men's Artistic Gymnastics at the 1932 Summer Olympics, and in 1955 and 1959 at the Pan American Games. From 1974 to 1998 it was included as an event for both genders at the Acrobatic Gymnastics World Championships. The event has also been contested since 1976 at the Trampoline World Championships. Since the recognition of Trampoline and Acrobatic Gymnastics as FIG disciplines in 1999, official Tumbling competitions are only allowed as an event in Trampoline gymnastics meets.
When was tumbling orginally contested at the Olympics?
