Communism
Communism (from Latin la, communis, lit=common, universal, label=none) is a far-left sociopolitical, philosophical, and economic ideology and current within the socialist movement whose goal is the establishment of a communist society, a socioeconomic order centered around common ownership of the means of production, distribution, and exchange which allocates products to everyone in the society.: "One widespread distinction was that socialism socialised production only while communism socialised production and consumption." Communist society also involves the absence of private property, social classes, money, and the state. Communists often seek a voluntary state of self-governance, but disagree on the means to this end. This reflects a distinction between a more libertarian approach of communization, revolutionary spontaneity, and workers' self-management, and a more vanguardist or communist party-driven approach through the development of a constitutional s ...

China Democratic League
The China Democratic League (CDL) is one of the eight legally recognized minor political parties in the People's Republic of China under the Chinese Communist Party's United Front. The CDL was originally founded in 1941 as an umbrella coalition group of the Chinese National Socialist Party, the Chinese Youth Party and the Chinese Peasants' and Workers' Democratic Party to fight the Imperial Japanese Army while providing for a "Third Way". By 2020, the party had grown to 330,600 members, making it the largest legally recognized minor political party in the People's Republic of China. Of all such parties it also has the most seats in the Standing Committee of the National People's Congress at 9 seats. However, it has 58 seats in the National People's Congress, 6 less than the Jiusan Society. History The China Democratic Political League was established in Chongqing on 19 March 1941, and changed its name to the China Democratic League in September 1944. At its formation, i ...

1952 Reorganisation Of Chinese Higher Education
The 1952 reorganisation of Chinese higher education (Chinese: 1952年中国高等院校院系调整) was a national policy under the Chinese Communist Party (CCP), which came into power in 1949, to adopt Soviet-styled higher education, which focused more on engineering education and technical training, in mainland China and to remove American influences among Chinese scholars. While eliminating private education, especially missionary higher education, the policy led to the state control over the higher education sector and the loss of faculty governance tradition since the 1920s. This served the Communist agenda to break up the prestigious universities established under the Republic of China, to weaken the historical ties between the university and the faculty, and to establish the political and organisational authority of the new Communist government over the higher education system. The reorganisation involved most of the higher education institutions in mainland China and infl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Second Sino-Japanese War
The Second Sino-Japanese War (1937–1945) or War of Resistance (Chinese term) was a military conflict that was primarily waged between the Republic of China and the Empire of Japan. The war made up the Chinese theater of the wider Pacific Theater of the Second World War. The beginning of the war is conventionally dated to the Marco Polo Bridge Incident on 7 July 1937, when a dispute between Japanese and Chinese troops in Peking escalated into a full-scale invasion. Some Chinese historians believe that the Japanese invasion of Manchuria on 18 September 1931 marks the start of the war. This full-scale war between the Chinese and the Empire of Japan is often regarded as the beginning of World War II in Asia. China fought Japan with aid from Nazi Germany, the Soviet Union, United Kingdom and the United States. After the Japanese attacks on Malaya and Pearl Harbor in 1941, the war merged with other conflicts which are generally categorized under those conflicts of World War II ...

Trigonometric Series
In mathematics, a trigonometric series is a infinite series of the form : \frac+\displaystyle\sum_^(A_ \cos + B_ \sin), an infinite version of a trigonometric polynomial. It is called the Fourier series of the integrable function f if the terms A_ and B_ have the form: :A_=\frac\displaystyle\int^_0\! f(x) \cos \,dx\qquad (n=0,1,2,3 \dots) :B_=\frac\displaystyle\int^_0\! f(x) \sin\, dx\qquad (n=1,2,3, \dots) The zeros of a trigonometric series The uniqueness and the zeros of trigonometric series was an active area of research in 19th century Europe. First, Georg Cantor proved that if a trigonometric series is convergent to a function f(x) on the interval , 2\pi/math>, which is identically zero, or more generally, is nonzero on at most finitely many points, then the coefficients of the series are all zero. Later Cantor proved that even if the set ''S'' on which f is nonzero is infinite, but the derived set ''S of ''S'' is finite, then the coefficients are all zero. In fact, ...

Doctor Of Philosophy
A Doctor of Philosophy (PhD, Ph.D., or DPhil; Latin: or ') is the most common degree at the highest academic level awarded following a course of study. PhDs are awarded for programs across the whole breadth of academic fields. Because it is an earned research degree, those studying for a PhD are required to produce original research that expands the boundaries of knowledge, normally in the form of a dissertation, and defend their work before a panel of other experts in the field. The completion of a PhD is often a requirement for employment as a university professor, researcher, or scientist in many fields. Individuals who have earned a Doctor of Philosophy degree may, in many jurisdictions, use the title '' Doctor'' (often abbreviated "Dr" or "Dr.") with their name, although the proper etiquette associated with this usage may also be subject to the professional ethics of their own scholarly field, culture, or society. Those who teach at universities or work in academic, e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
