Risk Assessment of Agricultural Products Supply-Chain Finance Based on D-S Theory

Agricultural products supply-chain finance, as one of the solutions to the issue of “capital problems” of agriculture, countryside and farmers, has proposed a kind of characteristics model to assess the risk of agricultural production, processing and marketing, which can improve the issue of farmers and enterprises lacking of funds. This model is proposed on the basis of uncertain information processing method of D-S theory and its data combination rules, combined with the “discount rate” correction model, and it includes a risk assessment index system of agricultural products supply-chain finance, fully considering the five aspects of production, processing, marketing, cooperation of supply chain and collateral. At last, a taro supply chain is taken for example. And the risk assessment of its supply-chain finance based on this model has been discussed in detail. And the result has proved that the model and its algorithm are practical and feasible.

Marx's Ground Rent Theory and Innovation of China's Urban Land System

China's traditional urban land system is established in highly centralized planned economy. This system negates functions of value law and economic law fundamentally,so it is not favorable for establishment of market mechanism and development of market economy. This study took Marx's ground rent theory as guidance,combined existing problems of China's land use system,and made analysis on innovation of China's urban land system from property right system,land market and land price.

Marx's Theory of Ground Rent and Nationalization of Land in China

It is essential to grasp scientific connotation of Marx's theory of ground rent,and actively explore and study theories and policies of socialist ground rent and nationalization of land through combining the certainty of existence of ground rent and actual situations of nationalization of land in China.

Ecological Significance in Marx's Theory of Metabolic Rift and Targeted Poverty Alleviation in Rural Areas

In expounding the historical conditions of " two necessities",Marx profoundly criticized the consequence of capitalist mode of production to society and ecology. Through the analysis of the capitalist relations of production,Marx systematically completed the viewpoint system about the material circulation of nature and human society,and foresaw the ecological consequences of capitalism to the world scientifically,taking ecology and mode of production as an organic whole. Since the socialism with Chinese characteristics entered into the new era,facing the serious ecological problems in the countryside in the process of modernization,the Party and the state,through the latest interpretation of the basic principles of Marxism,have creatively replaced the unsustainable poverty-alleviation policy with the targeted poverty-alleviation policy,thus making it have an important ecological orientation in the practice of poverty-alleviation in the countryside.

Anderson's Cognitive Theory and Learning Strategy Studies in Second Language Acquisition

Second language acquisition can not be understood without addressing the interaction between language and cognition. Cognitive theory can extend to describe learning strategies as complex cognitive skills. Theoretical developments in Anderson’s production systems cover a broader range of behavior than other theories, including comprehension and production of oral and written texts as well as comprehension, problem solving, and verbal learning.Thus Anderson’s cognitive theory can be served as a rationale for learning strategy studies in second language acquisition.

Detecting a Regularity in the Generation and Utilization of Primes in the Multiplicative Number Theory

If Goldbach’s conjecture is true, then for each prime number p there is at least one pair of primes symmetric with respect to p and whose sum is 2p. In the multiplicative number theory, covering the positive integers with primes, during the prime factorization, may be viewed as being the outcome of a parallel system which functions properly if and only if Euler’s formula of the product of the reciprocals of the primes is true. An exact formula for the number of primes less than or equal to an arbitrary bound is given. This formula may be implemented using Wolfram’s computer package Mathematica.

Five Dialectics of Xi Jinping's Theory on Ecological Progress

Xi Jinping's theory on ecological progress expands and deepens Marx's views on ecology and spells out the five dialectics between economic development and ecological conservation, the will of the nation and the will of the people, Chinese characteristics and global approaches, cultural concepts and institutional design, as well as the community of life and the community of shared future for mankind. It carries significance for our time and is weighted with theoretical value. At this stage, learning and studying the dialectics and value orientation of Xi Jinping's theory on ecological progress offers scientific guidance and value-based directions for China's efforts to promote an ecological civilization.

Motoyosi Sugita—A “Widely Unknown” Japanese Thermodynamicist Who Explored the 4th Law of Thermodynamics for Creation of the Theory of Life

The purpose of this paper is to introduce to you, the Western people, nowadays a “widely unknown” Japanese thermodynamicist by the name of Motoyosi Sugita and his study on the thermodynamics of transient phenomena and his theory of life. This is because although he was one of the top theoretical physicists in Japan before, during and after WWII and after WWII he promoted the establishment of the biophysical society of Japan as one of the founding members, he himself and his studies themselves have seemed to be totally forgotten nowadays in spite that his study was absolutely important for the study of life. Therefore, in this paper I would like to present what kind of person he was and what he studied in physics as a review on the physics work of Motoyosi Sugita for the first time. I will follow his past studies to introduce his ideas in theoretical physics as well as in biophysics as follows: He proposed the bright ideas such as the quasi-static change in the broad sense, the virtual heat, and the field of chemical potential etc. in order to establish his own theory of thermodynamics of transient phenomena, as the generalization of the Onsager-Prigogine’s theory of the irreversible processes. By the concept of the field of chemical potential that acquired the nonlinear transport, he was seemingly successful to exceed and go beyond the scope of Onsager and Prigogine. Once he established his thermodynamics, he explored the existence of the 4th law of thermodynamics for the foundation of theory of life. He applied it to broad categories of transient phenomena including life and life being such as the theory of metabolism. He regarded the 4th law of thermodynamics as the maximum principle in transient phenomena. He tried to prove it all life long. Since I have recently found that his maximum principle can be included in more general maximum principle, which was known as the Pontryagin’s maximum principle in the theory of optimal control, I would like to explain such theories produced by Motoyosi Sugita as detailed as possible. And also I have put short history of Motoyosi Sugita’s personal life in order for you to know him well. I hope that this article helps you to know this wonderful man and understand what he did in the past, which was totally forgotten in the world and even in Japan.

Dark Matter and the Energy-Momentum Relationship in a Hydrogen Atom

Einstein derived the energy-momentum relationship which holds in an isolated system in free space. However, this relationship is not applicable in the space inside a hydrogen atom where there is potential energy. Therefore, in 2011, the author derived an energy-momentum relationship applicable to the electron constituting a hydrogen atom. This paper derives that relationship in a simpler way using another method. From this relationship, it is possible to derive the formula for the energy levels of a hydrogen atom. The energy values obtained from this formula almost match the theoretical values of Bohr. However, the relationship derived by the author includes a state that cannot be predicted with Bohr’s theory. In the hydrogen atom, there is an energy level with n = 0. Also, there are energy levels where the relativistic energy of the electron becomes negative. An electron with this negative energy (mass) exists near the atomic nucleus (proton). The name “dark hydrogen atom” is given to matter formed from one electron with this negative mass and one proton with positive mass. Dark hydrogen atoms, dark hydrogen molecules, other types of dark atoms, and aggregates made up of dark molecules are plausible candidates for dark matter, the mysterious type of matter whose true nature is currently unknown.

何谓新质生产力——马克思的生产力理论新解

新质生产力是一个复杂的系统,包括哲学基础、一般性质和中国特点三个方面的内容。新质生产力的哲学基础是马克思的生产力理论。马克思的生产力理论创造是以19世纪的资本主义大机器生产为经验原型的,但马克思在以他的历史哲学来审视19世纪资本主义大机器生产的过程中,揭示了生产力发展的内在机制,预示了生产力的未来发展必然是科学技术和精神文化的创造占据主导地位。这些思想构成了马克思的生产力理论与新质生产力的接合点。新质生产力的一般性质及其构成是由数字劳动方式决定的,数字劳动方式具有三个特点:一是在技术构成上,实现了现代科学与复杂的技术系统和现代生产结构的有机结合;二是在资本的构成上,以科学技术和新思想创造为主体的非物质劳动进入资本构成,与工业、农业等物质劳动的资本共同构成了新的资本结构;三是在思想构成上,把系统哲学和系统技术结合起来,建构了以通信、信息控制研究为核心的思维范式。上述三个特点凸显了科学技术、人的思想创造和文化精神在新质生产力中的主导地位,构成了新质生产力的一般规定。新质生产力的中国特色是与中国式现代化的道路相联系的,它的思想基础是中国特色社会主义,它的实践基础是中国改革开放以来创造的新质生产力发展模式。中关村电子一条街的发展,就是近40年来中国新质生产力发展史的一个缩影。

基于多元数据的夏季鸡舍环境质量评价及其对产蛋性能的影响

蛋鸡舍环境质量直接影响蛋鸡产蛋性能。为探究夏季蛋鸡舍环境质量及其对产蛋性能的影响,研究提出基于多元数据的分析方法,首先采集鸡舍内7类关键环境因子数据,按照热环境、光环境和气体环境分组,再根据改进D-S证据理论规则进行迭代融合,得到蛋鸡舍各检测点环境质量的综合评价结果,进而分析其对产蛋性能的影响。以夏季八层层叠式蛋鸡舍为试验鸡舍开展试验。结果显示:八层层叠式蛋鸡舍下四层的环境质量和平均产蛋率的最优位置均处于鸡舍前端;平均产蛋率最差的位置处于鸡舍中端,该位置环境质量综合评价结果为一般;上四层平均产蛋率最优位置为鸡舍中端,该位置环境质量综合评价结果为适宜;平均产蛋率最差位置和环境质量最差位置均为鸡舍后端(靠近风机端)。在试验鸡舍所有检测点中,平均产蛋率高于86%的检测点,环境质量综合评价结果大都为适宜,平均产蛋率低于86%的检测点,环境质量综合评价结果为一般或差,鸡舍内各检测点环境质量综合评价结果与平均产蛋率的变化趋势高度一致。该研究为准确评价蛋鸡舍环境质量,揭示蛋鸡舍环境质量对产蛋性能的影响提供了一种行之有效的方法。

劳动生产率与社会生产规模对利润引致需求的作用——马克思经济理论视阈下的函数与分析

以马克思经济理论为基础,分析劳动生产率和社会生产规模对利润引致需求的作用、数量关系及其本质所在,社会生产规模可以用劳动者人数和资本数量两个方面来衡量。当劳动生产率提高和资本数量扩张时,利润引致需求不一定增长;如果资本有机构成的增长率高于劳动生产率和资本数量的增长率时,利润引致需求会下降,这就是经济增长中的总需求下降或总需求不足加剧现象。预期的不稳定性和投资在形成市场供给和需求上的时间差,会导致利润引致需求具有内在的不稳定性,从而导致宏观经济内在的不稳定性和周期性。在宏观经济政策制定中,特别关注这两点,具有至关重要的意义。在马克思经济理论基础上构建利润引致需求函数关系及其数量分析,并由此出发解决宏观经济运行中的现实问题,也证明了马克思主义理论的生命力。
