Relationship between the Three Laws of Dialectics of Nature and Agricultural Development

Based on the three laws of dialectics of nature-the law of unity of opposites, the law of mutual change of quality and the law of negation of negation, this paper analyzes the relationship between the three laws and agricultural development, and proposes making good use of the three laws to promote the better development of agriculture and realize agricultural modernization.

Dialectics of nature： Temporal and spatial regulation in material sciences

The cooperative interaction distance measure has been proposed as a novel law pertaining to dialectics of nature, and has been extensively carried out in the design of functional nanomaterials. However, the temporal and spatial dimensions are akin to yin and yang, and thus temporal regulation needs to be accounted for when implementing the above-mentioned principle. Here, we summarize recent advances in temporally and spatially regulated materials and devices. We showcase the temporal regulation of organic semiconductors for organic photovoltaics （OPVs） using the example of exciton lifetime manipulation. As an example of spatial regulation, we consider the distribution of charge carriers in core-shell quantum dot （QD） nanocrystals for modulating their optical properties. Long exciton lifetime can in principle increase the exciton diffussion length, which is desiable for high-efficiency large-area OPV devices. Spatially regulated QDs are highly valuable emitters for light-emitting applications. We aim to show that cooperative spatio-temporal regulation of nanomaterils is of vital importance to the development of functional devices.

Reshaping Nature:Humanism,Ethnicity,and Literary and Film Production of the Story of Daji

This article discusses the role that nature plays in ethnic literature and films in the Seventeen-Year Period(1949-66).It takes the story of Daji and Her Fathers as an example and investigates the ways in which nature features in the reconstruction of ethnic identity in the formation of a multiethnic nation as in the case of China.I will explore three aspects:first,the debate on humanism,which was closely related to ethnic minority film production at the time.A central issue of the debate then was the question of“humanistic”-that is,affective,emotional,subjective,and most importantly,natural-expression in literary and art works.Ethnic minority identity,with its unique status,was given some latitude for humanistic expression and“natural”understanding.Second,due to ethnic minority groups’special significance in China’s nation-building,a reconstruction of ethnic minority nature became imperative for the People’s Republic of China.This reconstruction involves mostly restructuring a“second nature,”or dialectic nature of minority under the socialist mandate.This dialectic nature demands something more than natural,immediate constituents and requires a socially and politically mediated ethnic minority nature that is aligned with multiethnic nationality.Third,this dialectic nature is to be formed following Marxist dialectical materialism,mainly through the means of social(ist)labor that changes nature.

Science and the Rebuilding of the ＂Rational Subject＂ in 1980s China

Throughout the history of modern and contemporary China, the concept of ＂science＂ maintains a crucial significance. Since the May Fourth period, ＂science＂ represented the advanced civilization and culture of the West Because of its critical role, quarrels over the question of science were abundant in China in the years after the Cultural Revolution, notably in the ＂debates on humanism and science＂ （kexue lunzheng）. Following that, scientific Marxism, which is based on natural dialectics, surpassed other discourses to become of dominated importance to the intellectual discourses of post-Mao China. Scientific Marxism was considered the highest form of truth in revolutionary China, when transcendental truth reigned supreme. Following the Cultural Revolution, intellectuals embracing scientific thought sought to locate ＂another science＂ with which to replace scientific Marxism. Addressing an understudied yet crucial aspect of 198os intellectual history, this paper explores the central ideas and discourses of scientism in this historical moment, as well as the intellectuals who took part in its construction and controversy.
