Public Relations Clients Unlike in the United Kingdom, where members of the PR Consultants Association are required to have an updated, published list of all clients, the U.S. Council of PR decided against a proposal for the disclosure of client lists. Therefore the worlds biggest PR agencies, which are mostly U.S. based, are still in the position to make a secret of their clients. Although public relations activity is mostly associated with marketing and issues management for corporate firms, also PR for nations, politicians and NGOs is common. Among the first to pursue PR for nations was Edward L. Bernays, one of the founders of modern public relations. Besides his activity in the Creel-Committee, which was responsible for the American propaganda during World War I, he also worked as a PR consultant for Lithuania and India. With his engagement for United Fruit he was moreover actively involved in the Cold War - especially in the overthrow of the Guatemalan government of Guzman.

Intellectual property Intellectual property, very generally, relates to the output that result from intellectual activity in the industrial, scientific, literary and artistic fields. Traditionally intellectual property is divided into two branches: 1) industrial property (inventions, marks, industrial designs, unfair competition and geographical indications), and 2) copyright. The protection of intellectual property is guaranteed through a variety of laws, which grant the creators of intellectual goods, and services certain time-limited rights to control the use made of their products.

MIT The MIT (Massachusetts Institute of Technology) is a privately controlled coeducational institution of higher learning famous for its scientific and technological training and research. It was chartered by the state of Massachusetts in 1861 and became a land-grant college in 1863. During the 1930s and 1940s the institute evolved from a well-regarded technical school into an internationally known center for scientific and technical research. In the days of the Great Depression, its faculty established prominent research centers in a number of fields, most notably analog computing (led by Vannevar Bush) and aeronautics (led by Charles Stark Draper). During World War II, MIT administered the Radiation Laboratory, which became the nation's leading center for radar research and development, as well as other military laboratories. After the war, MIT continued to maintain strong ties with military and corporate patrons, who supported basic and applied research in the physical sciences, computing, aerospace, and engineering. MIT has numerous research centers and laboratories. Among its facilities are a nuclear reactor, a computation center, geophysical and astrophysical observatories, a linear accelerator, a space research center, supersonic wind tunnels, an artificial intelligence laboratory, a center for cognitive science, and an international studies center. MIT's library system is extensive and includes a number of specialized libraries; there are also several museums.

Gaius Julius Caesar Gaius Julius Caesar (100-44 BC) was a Roman Statesman who came to power through a military career and by buying of votes. His army won the civil war, run over Spain, Sicily and Egypt, where he made Cleopatra a Queen. For reaching even more power he increased the number of senators. But he also organized social measures to improve the people's food-situation. In February 44 BC he did not accept the kingship offered by Marc Anthony, which made him even more popular. One month later he was murdered during a senate sitting.
