What idea introduced by malinowski is fundamental to all research conducted by contemporary cultural anthropologists?
rosijanka [135]

The answer is<u> "Participant observation".</u>

It can be be said that to a specific degree Malinowski is supported in his case that participant observation enables anthropologists to see the 'local's perspective.' Significantly, Malinowski was one of the first to be considered important for the technique for participant observation in anthropological hands on work. It was his conviction that with a specific end goal to feel the local lifestyle, one should completely drench themselves in the way of life to escape previously established inclinations, while similarly not adopting a disengaged strategy that would result in 'dead material.

What was the outcome of pro-democracy demonstrations in Tiananmen Square in 1989?
Neporo4naja [7]

Answer:

      The Tiananmen Square protests were student-led demonstrations calling for democracy, free speech and a free press in China. They were halted in a bloody crackdown, known as the Tiananmen Square Massacre, by the Chinese government on June 4 and 5, 1989.

       Pro-democracy protesters, mostly students, initially marched through Beijing to Tiananmen Square following the death of Hu Yaobang. Hu, a former Communist Party leader, had worked to introduce democratic reform in China. In mourning Hu, the students called for a more open, democratic government. Eventually thousands of people joined the students in Tiananmen Square, with the protest’s numbers increasing to the tens of thousands by mid-May.

       At issue was a frustration with the limits on political freedom in the country—given its one-party form of government, with the Communist Party holding sway—and ongoing economic troubles. Although China’s government had instituted a number of reforms in the 1980s that established a limited form of capitalism in the country, the poor and working-class Chinese still faced significant challenges, including lack of jobs and increased poverty.

      The students also argued that China’s educational system did not adequately prepare them for an economic system with elements of free-market capitalism.

       Some leaders within China’s government were sympathetic to the protesters’ cause, while others saw them as a political threat.

Martial Law Declared

       On May 13, a number of the student protesters initiated a hunger strike, which inspired other similar strikes and protests across China. As the movement grew, the Chinese government became increasingly uncomfortable with the protests, particularly as they disrupted a visit by Prime Minister Mikhail Gorbachev of the Soviet Union on May 15.

       A welcome ceremony for Gorbachev originally scheduled for Tiananmen Square was instead held at the airport, although otherwise his visit passed without incident. Even so, feeling the demonstrations needed to be curtailed, the Chinese government declared martial law on May 20 and 250,000 troops entered Beijing.

       By the end of May more than one million protesters had gathered in Tiananmen Square. They held daily marches and vigils, and images of the events were transmitted by media organizations to audiences in the United States and Europe.

       Tiananmen Square Massacre

While the initial presence of the military failed to quell the protests, the Chinese authorities decided to increase their aggression. At 1 a.m. on June 4, Chinese soldiers and police stormed Tiananmen Square, firing live rounds into the crowd.
