The overall influential power of China development on international community was misunderstood. What we see is the role of "China Factor" in different fields. In the process of economic globalization, what economic system of capitalist market has seen is "China's cheap labor", "China's loose economic system environment", "earlier abuse of unlimited resource environment", "China's broad consumption market" and "demographic dividend". In global or Asian financial crisis, what other countries valued was China's "foreign currency" accumulated over the years. In global gov- ernance or crisis management, what international community expected was "China's obligations and responsibilities" without the right of speech, etc.. All these are the "passive" roles produced by "a single factor" in definite fields. The active and initiative role China will play in international community still needs time and the continuous efforts of several generations. China once was a big country that had significant inftuential power on the world, and China's renaissance is a normal process of development of things. What excessive talks about its influential power reflect may be the lack of China's influence.展开更多

To fulfill the two conflicting while complementary objectives, a systematic approach for life cycle design of a chemical product is proposed in this article. Multiattribute decision-making is adopted in a trade-off consideration of both technical economical evaluation and environmental impacts assessment using the analytic hierarchy process (AHP) approach. On the basis of an evaluation of the relative importance of the criteria multicriteria decision making is performed. In this study, an AHP model is used to derive single a criteria score by analyzing the environmental impact and life cycle cost of a product, respectively. And a fluctuant weight analysis is put forth to calculate the integrated index of the product to enable products to be ranked or selected intuitionally and conveniently. The proposed AHP model has been applied to a case study, a comparative study on chamber cleaning with NF3 and C2F6. The resuits show that the protposed AHP model is Capable of providing a rational and relevant evaluation.展开更多

The decou..."Decoupling" refers to the divergence of business cycles among different countries, while "re-coupling" corresponds to the convergence or the synchronization of business cycles among different countries. The decoupling debate is popular in the field of economics, especially after global financial crisis. As trade integration increased among Asian countries, business cycle synchronization among these countries was expected to increase through trade transmission. The aim of this study is to discover whether there has been decoupling or convergence of business cycles through various trade channels. However, theoretically, increased trade can lead to business cycle synchronization either rising or falling. Inter-industry trade resulting in higher specification will induce less synchronized business cycles, while intra-industry trade could lead to increased business cycle synchronization. Thus, it is important to distinguish between intra- and inter-industry trade flows. Both correlation and dynamic factor models are utilized to study the evolution of global business cycle linkages. Results indicate that the world factor has become less important in explaining macroeconomic fluctuations from sub-period 1961-1984 to sub-period 1985-2007, while regional factors do not play an important role in explaining aggregate volatility, with the expectation of consumption. Overall, the explanatory power of country factors increases. Domestic consumption and domestic investment variances are more driven by country and idiosyncratic factors than by the world factor, contrary to the output growth fluctuations. Regional factors and country factors also play a more prominent role in explaining gross import fluctuations than in explaining gross exports. Results cast doubt on the strong forms of both the decoupling and the re-coupling hypothesis.展开更多

This article discusses and criticizes such attitude as the strategic methodological platform. The theoretical backgrounds of the presented analysis lay in the Schumpeterian innovation theory of economic development and the Neo-Schumpeterian approaches concerning decisive value of structural and technological change for economic growth. It gives arguments for standpoint that a follow-up economic development can be successful if a country will be able to have expansion of new modem sectors and more innovative structure of production, as investments in the process of innovation must guarantee a permanent structural reform of the national economy on a new technological basis. One of the main means of realization should be the diversification of the organizational forms of the national economy, ensuring the cooperation of small, medium and large companies within the innovation "science-technology-production" cycle. Conclusion that in transitive countries and in Ukraine the contemporary innovation policy should provide effective mechanisms of investing into large-scale structural changes for the benefit of the sectors of the fifth and sixth technological paradigm.展开更多

Others,. however, have pointed out that the human rights institutional and political hegemony makes other valuable emancipatory strategies less available, and that this foregrounds problems of participation and procedure at the expense of distribution (Kennedy 2005). Finally, others have explained how the abstractedness of the category entails a de-politicization (Rancière 2004; Zizek 2005; Douzinas 2007) or an emptiness that, of course, can be filled by progressive activism, but whose substance is easily reappropriated by those in power (Miéville 2005). By engaging with the above-mentioned perspectives, and following the decolonial approach (Mignolo 2009; 2011), I suggest that the category human rights can be decolonized and being used for progressive agendas only after a comprehensive critique of liberal legality (that entails a critique of liberal abstract rationality, political economy, and modernity/coloniality) has been performed.展开更多

The author shows why some reasons, according to which we should use mathematics in (economic) theory, are not convincing (they are even tautological), and what does mathematization have to do with arbitrariness of the orthodox economic theory. The author also shows why using game theory (a mathematical discipline) in modem microeconomics does not yield knowledge and correct explanation of economic situations and phenomena. At the end, the author presents fundamental questions that form the basis of economic science and its qualitative research methods, and shows what their practical relevance is. The purpose of this article is to argue, contrary to common opinion, that there can be an exact and objective science of economic phenomena that does not necessarily use modem mathematical theories or methods to explain these phenomena.展开更多

How to assess various contributing factors for carbon emission is of great importance to find out the key factors and promote carbon emission reduction. In this paper, the author constructs an identical equation for carbon emission, based on the economic aggregate, the economic structure, the efficiency of energy utilization, the structure of energy consumption, and the coefficient of carbon emission; by applying to LMDI decomposition technology, the author analyzes the carbon emission of China from 1995 to 2007 at industrial level and regional level. The results show that the expansion of economic aggregate is the main reason for China' s rapidly increasing carbon emission and the increase of energy utilization efficiency is the key factor that can hold back the increase of carbon emission. In addition, the change of industrial structure or regional structure and the change of traditional energy structure have limited influence on the carbon emission, and their potentials have not yet been exploited. At the end of this paper, the author proposes the efforts that China should make to reduce carbon emission.展开更多

However, it is a fact that the world is confronted with huge contradictions that oppose such qualifications. Obviously, one of the most striking and almost unbelievable realities tells us about inhumane and uncivilized actions of child exploitation in "entrepreneurial" purposes in the widest range of exploitation and abuse. Current period of economic crisis tells us even more about the rising crisis of moral, which is, in statistical terms, confirmed by a rising number of exploited children in a global framework, and even in some national frameworks as well. With that, some positive results about the diminishing number of exploited children are devaluated. The question is what are the "limits" of such behavior of groups, organizations, and individuals whose behavior is, obviously, tolerated in the frameworks of certain national economies. Does this behavior have clarity as a part of modem society? Or, even more severe, for how long can we as a society close our eyes in front of such facts? Do we even have the right? In this paper, the authors strive towards focusing and objectifying the global problem of exploitation and abuse of children in "entrepreneurial" purposes, primarily with the purpose of updating all parts of the society of this paradox and the need of raising the awareness and teaching all relevant factors--from institutions to individuals, with the purpose of resolving and more neutralize the equivalents of this uncivilized and non-entrepreneurial "phenomenon", as well as approaching the same in the framework of different actions with broadest measures possible and with all disposable assets.展开更多

The rice straws were pretreated by acid-catalyzed steam explosion, and the reaction efficiency, toxicity control, and process economic feasibility were studied. Mass transfer resistance to the hydrolysis reaction was reduced by grinding with glass beads. A higher glucose concentration could be obtained by feeding more cellulose in the hydrolysis reaction; however, this also resulted in the production of undesired byproducts. Thus, a soaking process for the cellulose solids in water was developed to effectively reduce the generation of byproducts in the hydrolysis reaction. The resulting food-grade glucose solution can provide 414 kilocalories per liter, and could be used during a food-shortage crisis in the future.The current production cost is estimated to be 0.82 USD·L^(-1).展开更多

The criticism pointed out the way for the solution of the ecological problems and showed the seeds of ecological civilization. The paper reveals the ontology about ecological civilization and generation and elimination of crisis through analyzing the Marxist thought of ecological civilization in manuscripts. The paper believes that Marxist thought of ecological civilization may enlighten us to carry forward and develop it with guidance, sense and theory. We sincerely expect that the thought of ecological civilization will be rooted in the hearts of the people deeply by means of the rise of "green" concept and the education of ecological ethics. The paper has important theoretical and practical value on deeply understanding the relationship between human and nature with scientific development angle of view, conquering the ecological crisis of globalization scientifically and building and developing ecological civilization of Chinese characteristic socialism energetically.展开更多

The as-obtained SBP-BF4 was dissolved in AN and used as the electrolyte for supercapacitor. Electrochemical measurements demonstrate that, compared with commercial electrolyte TEMA-BF4/AN, SBP-BF4/AN exhibits high ionic conductivity, lower resistance and improved cycling performance, which is due to its smaller ion size and stable symmetry structure.展开更多
