input: Several techniques are used by DJs as a means to better mix and blend recorded music. These techniques primarily include the cueing, equalization and audio mixing of two or more sound sources. The complexity and frequency of special techniques depends largely on the setting in which a DJ is working. Radio DJs are less likely to focus on advanced music-mixing procedures than club DJs, who rely on a smooth transition between songs using a range of techniques. However, some radio DJs are experienced club DJs, so they use the same sophisticated mixing techniques. Club DJ turntable techniques include beatmatching, phrasing and slip-cueing to preserve energy on a dance floor. Turntablism embodies the art of cutting, beat juggling, scratching, needle drops, phase shifting, back spinning and more to perform the transitions and overdubs of samples in a more creative manner (although turntablism is often considered a use of the turntable as a musical instrument rather than a tool for blending recorded music). Professional DJs may use harmonic mixing to choose songs that are in compatible musical keys. Recent advances in technology in both DJ hardware and software can provide assisted or automatic completion of some traditional DJ techniques and skills. Examples include phrasing and beatmatching, which can be partially or completely automated by utilizing DJ software that performs automatic synchronization of sound recordings, a feature commonly labelled "sync". Most DJ mixers now include a beat-counter which analyzes the tempo of an incoming sound source and displays its tempo in beats per minute (BPM), which may assist with beatmatching analog sound sources. In the past, being a DJ has largely been a self-taught craft but with the complexities of new technologies and the convergence with music production methods, there are a growing number of schools and organizations that offer instruction on the techniques.

input: Rockefeller traveled widely and met with both foreign rulers and U.S. presidents, beginning with Dwight D. Eisenhower. At times he served as an unofficial emissary on high-level business. Among the foreign leaders he met were Saddam Hussein, Fidel Castro, Nikita Khrushchev, and Mikhail Gorbachev. In 1968, he declined an offer from his brother Nelson Rockefeller, then governor of New York, to appoint him to Robert F. Kennedy's Senate seat after Kennedy was assassinated in June 1968, a post Nelson also offered to their nephew John Davison "Jay" Rockefeller IV. President Jimmy Carter offered him the position of United States Secretary of the Treasury but he declined. Rockefeller was criticized for befriending foreign autocrats in order to expand Chase interests in their countries. The New York Times columnist David Brooks wrote in 2002 that Rockefeller "spent his life in the club of the ruling class and was loyal to members of the club, no matter what they did." He noted that Rockefeller had cut profitable deals with "oil-rich dictators", "Soviet party bosses" and "Chinese perpetrators of the Cultural Revolution". Rockefeller met Henry Kissinger in 1954, when Kissinger was appointed a director of a seminal Council on Foreign Relations study group on nuclear weapons, of which David Rockefeller was a member. He named Kissinger to the board of trustees of the Rockefeller Brothers Fund, and consulted with him frequently, with the subjects including the Chase Bank's interests in Chile and the possibility of the election of Salvador Allende in 1970. Rockefeller supported his "opening of China" initiative in 1971 as it afforded banking opportunities for the Chase Bank. Though a lifelong Republican and party contributor, he was a member of the moderate "Rockefeller Republicans" that arose out of the political ambitions and public policy stance of his brother Nelson. In 2006 he teamed up with former Goldman Sachs executives and others to form a fund-raising group based in Washington, Republicans Who Care, that supported moderate Republican candidates over more ideological contenders.

input: Initially, Borlaug's work had been concentrated in the central highlands, in the village of Chapingo near Texcoco, where the problems with rust and poor soil were most prevalent. He realized that he could speed up breeding by taking advantage of the country's two growing seasons. In the summer he would breed wheat in the central highlands as usual, then immediately take the seeds north to the Yaqui Valley research station near Ciudad Obregon, Sonora. The difference in altitudes and temperatures would allow more crops to be grown each year. Borlaug's boss, George Harrar, was against this expansion. Besides the extra costs of doubling the work, Borlaug's plan went against a then-held principle of agronomy that has since been disproved. It was believed that to store energy for germination before being planted, seeds needed a rest period after harvesting. When Harrar vetoed his plan, Borlaug resigned. Elvin Stakman, who was visiting the project, calmed the situation, talking Borlaug into withdrawing his resignation and Harrar into allowing the double wheat season. As of 1945, wheat would then be bred at locations 700 miles (1000 km) apart, 10 degrees apart in latitude, and 8500 feet (2600 m) apart in altitude. This was called "shuttle breeding". As an unexpected benefit of the double wheat season, the new breeds did not have problems with photoperiodism. Normally, wheat varieties cannot adapt to new environments, due to the changing periods of sunlight. Borlaug later recalled, "As it worked out, in the north, we were planting when the days were getting shorter, at low elevation and high temperature. Then we'd take the seed from the best plants south and plant it at high elevation, when days were getting longer and there was lots of rain. Soon we had varieties that fit the whole range of conditions. That wasn't supposed to happen by the books". This meant that the project would not need to start separate breeding programs for each geographic region of the planet.
