In 1996–1997, a research study was conducted on a large population of middle age students in the Cherry Creek School District in Denver, Colorado, USA. The study showed that students who actively listen to classical music before studying had higher academic scores. The research further indicated that students who listened to the music prior to an examination also had positively elevated achievement scores. Students who listened to rock-and-roll or country had moderately lower scores. The study further indicated that students who used classical during the course of study had a significant leap in their academic performance; whereas, those who listened to other types of music had significantly lowered academic scores. The research was conducted over several schools within the Cherry Creek School District and was conducted through University of Colorado. This study is reflective of several recent studies (i.e. Mike Manthei and Steve N. Kelly of the University of Nebraska at Omaha; Donald A. Hodges and Debra S. O'Connell of the University of North Carolina at Greensboro; etc.) and others who had significant results through the discourse of their work.
What years was the study conducted in?
1996–1997

The centre of Paris contains the most visited monuments in the city, including the Notre Dame Cathedral and the Louvre as well as the Sainte-Chapelle; Les Invalides, where the tomb of Napoleon is located, and the Eiffel Tower are located on the Left Bank south-west of the centre. The banks of the Seine from the Pont de Sully to the Pont d'Iéna have been listed as a UNESCO World Heritage Site since 1991. Other landmarks are laid out east to west along the historic axis of Paris, which runs from the Louvre through the Tuileries Garden, the Luxor Column in the Place de la Concorde, the Arc de Triomphe, to the Grande Arche of La Défense.
Since when have the banks of the Seine from the Pont de Sully to the Pond'lena been listed as a UNESCO World Heritage site?

By 1353, the three original cantons had joined with the cantons of Glarus and Zug and the Lucerne, Zürich and Bern city states to form the "Old Confederacy" of eight states that existed until the end of the 15th century. The expansion led to increased power and wealth for the federation. By 1460, the confederates controlled most of the territory south and west of the Rhine to the Alps and the Jura mountains, particularly after victories against the Habsburgs (Battle of Sempach, Battle of Näfels), over Charles the Bold of Burgundy during the 1470s, and the success of the Swiss mercenaries. The Swiss victory in the Swabian War against the Swabian League of Emperor Maximilian I in 1499 amounted to de facto independence within the Holy Roman Empire.
Which Swiss victory in 1499 amounted to de facto independence within the Holy Roman Empire?
Swabian War
