China, as a state member of WTO, is challenged by the WTO's agreements and the principles to guideline China sustainable forest development in the future. Forest resources in China will be protected as the basic sections of natural resources. The administrative function of Chinese government will be reformed by the condition of WTO's principles. So, the aim of China forest sustainable development is prior to deal with the relationship between the environment protection and development of economy. Under the condition of the WTO's principles and as a base on the international customary laws, the issues of China forest sustainable development focus on the China forest system reformation that applies for the China nature forest stratagem by the laws and protects the China environment for the sustainable development under the condition of science development, especially in the China forest protection and in dealing with the relationship among the environment and the economy development and others. Establishing the zoological forest industry is basic requirement by both the WTO's agreements and the WTO's principles, especially under the GATT 1947 Art XX, and other principles to protect the China forest sustainable development and to create the international environment for China forest.

Under the proposed kinetic approach, the uncertainty principle covers a wider spectrum of processes of approaching to equilibrium and object formation, than the absolute certainty principle. It refers, in particular, to nano-range-of-problems and mesoscopics as well as to cosmology. Both principles predict formation of objects that are not well-known or, at least, well-described so far. Among these are neutron-rich super-heavy and giant nuclei, biologic and organic-silicon mesoobjects, cosmological objects with the sizes considerably exceeding the size of a light sphere.展开更多

It is important for both scholars and policymakers to review the characteristics of China's economy in its present stage in accordance with economic principles-principles that reflect every aspect of economic and social life and macroeconomic regulation. In this paper, we attempt to unravel the characteristics of China's new era from three perspectives-historical materialism, dialectic materialism and epistemology, and in light of economic principles at the three levels of resource factors, modes of production and regulation of resource allocation. Based on these perspectives, this paper further identifies the characteristics of China's new era from nine aspects, including globalization, modernization, the primary stage of socialism, new development concepts, supply-side reforms, the guideline of seeking steady progress, the mentality of scope, bottomline mindset and strategic composure. From the three different levels, this paper summarizes and applies economic principles to propose solutions to the problems and challenges facing China in the new era. The findings of the paper are also relevant to implementation of the guidelines CPC Central Committee General Secretary Xi Jinping noted in his report to the 19 th CPC National Congress.展开更多

This fact is typically interpreted as support for special relativity. On the other hand, the same century produced proof that clocks at various locations in the gravitational field also read differently, and this fact is explained by general relativity, which is, in general, not Lorentz transformable. This paper establishes a common framework for the physics of clocks in these different situations.展开更多

Software productivity was measured in function points per person hours, and software development time was measured in number of elapsed days. Using field data on over 130 field software projects from various industries, we empirically test the impact of team size, integrated computer aided software engineering (ICASE) tools, software development type, software development platform, and programming language type on the software development productivity and development time. Our results indicate that team size, software development type, software development platform, and programming language type significantly impact software development productivity. However, only team size significantly impacts software development time. Our results indicate that effective management of software development teams, and using different management strategies for different software development type environments may improve software development productivity.展开更多

Some recent initiatives at global, regional and local level are pointed and some conceptual trends and deployment strategies advance towards the consolidation of the principles of sustainable development, despite several difficulties for effectively reaching its goals. The trend of gradual changes in the models of developing nations and in the patterns of production and consumption is portrayed objectively, seeking to correlate with principles of environmental economics and green economy, since Cecil Pigou and Stuart Mill principles to recent researches as Kenneth Boulding, Herman Daly, Nicholas Georgescu-Rogen, Franz Capra, Ignacy Sachs, Edgar Morin, beyond others. The ability of the United Nations and governments to intervene in neoliberal logic aiming wider benefit to society and the reduction of the negative effects of market distortions, as striking on the global stage, represents a true redemption of the principles advocated by Cecil Pigou, at the beginning of the last century, both for the global economy and for their effects on environmental and social conflicts, social exclusion resulting from the current economic systems which are not necessary new strategies, principles, or economic formulas, but decision making to tackle the market with seriousness to promote equity, social justice and environmental sustainability, without sacrificing progress and development, as evident in the current discussion of social inclusion and the convergence of individual and collective interests, so far in the development model based on increasing production and consumption, yet with little environmental responsibility.展开更多
