However, this transition is associated with major risks, including adapting to decelerating economic growth. While recognizing the move toward a service-based economy, China must seek to prevent the risk of "manufacturing hollowing out. "' It must also avoid the "technology upgrade trap" while taking advantage of increasingly sophisticated industrial structures. Efforts must also be made to: (1) promote the integration of lT tools and meet risks arising from the New Industrial Revolution; (2) resolve liability risks arising from capacity reduction; and (3) expedite the transition to a functional industrial policy and prevent the failure of a functional industrial policy. In climbing up the global value chain, China must confront the competitive pressures from advanced and emerging economies on both high- and low-end processes of the global value chain.展开更多

These tendencies are becoming more and more tense, so that we will reach a point when even processes, that from technological point of view fulfill high requirements of the foundry industry, must be replaced by more ecologically-friendly solutions. Hence, technologies using synthetic resins as binding materials will be limited. This paper presents some predictable development tendencies of moulding and core sands. The increasing role of inorganic substances will be noticed, including silicate binders with significantly improved properties, such as improved knock-out property or higher reclamation strength. Other interesting solutions might also be moulding sands bonded by geo-polymers and phosphate binders or salts and also binders based on degradable biopolymers. These tendencies and the usefulness of these binders are put forward in this paper.展开更多

With its coming, quite a few people have tried translating the subtitles to help those unfamiliar with foreign languages better understand the films. Some of their works are good. At the same time, some people have done research concerning FST to successfully put forward some strategies and methods to help those film subtitle translators. They see into FST from different perspectives such as the Skopostheory, the Functional Equivalence theory and the Relevance Theory. However, few people tried researching FST from a cultural perspective.The author decides to probe into FST from an entirely new perspective. In this paper, the author introduces Hall's High and Low Context theory and puts forward four tendencies in FST.展开更多

The 48f oxygen position parameter x, cohesive energy, bond type and defect-formation energy are discussed. The results show that parameter x can be used to indicate the disordering tendencies within a given pyrochlore family. Bond type, cohesive energy and defect-formation energies can be used to explain some experimental observations, but they are not determined exclusively by radiation "resistance" for a different pyrochlore family.展开更多

The focus in this chapter is on the apparent French/English language contest over supremacy. Here comes the current investigation that aims at gauging Moroccan’s perceptions of French and English through a language questionnaire.Responses were subjected to statistical analyses to support or reject the hypothesis that gender, age and language proficiency affect Moroccans’ evaluations of French and English.The study reveals that Moroccans’ attitudes towards English are significantly more favorable than those towards the French language. Age, but not gender, has turned out to have a statistically significant difference in the overall evaluation of French and English.These evaluations have also been shown to correlate with the respondents’ French and English language proficiency. The result of this study is an indication that Moroccans’attitudes toward French and English are undergoing a change from a conventional preference for French to a recent favor of English whose phenomenal growth globally may have affected language attitudes locally.展开更多

The particular mains concern the political economy models of foreign trade policy, protectionistic pressures in different political system, the level of protectionistic pressures, food producer pressures, international trade liberalization, and environmental protection bilateral tendencies in the common trade policy of the EU and the respond of the EU to the economic crisis, it must be emphasized that on a theoretical level, understanding the choice of trade policies between liberalizm and protectionisme is very important. Despite the undeniable benefits of the multilateral WTO forum for trade liberalisation, the rapid increase of North-South bilateral and multilateral Free Trade Areas (FTAs) begs a systematic explanation for why some forums are prioritized relative to others.展开更多

Furthermore, the measured temperature was studied by integrating wavelet transform, nonlinear characteristic parameters extraction and fuzzy comprehensive evaluation. The results indicate that only the ore samples 1, 2, 6 and 9 have obvious self-heating phenomenon, and their self-heating initiative temperatures are 220 ℃, 239 ℃, 220 ℃ and 220 ℃, respectively, which means that they are difficult to produce self-heating under normal mining conditions. The correlation dimension of self-heating process is fraction and the maximum Lyapunov exponent is positive, which means that it is feasible to study the self-heating process based on chaotic dynamics theory. The nonlinearities of self-heating process of these four samples (ore samples 1, 2, 6 and 9) are 0.8227, 0.7521, 0.9401 and 0.8827 respectively and the order of the samples according to these results is: sample 6, sample 9, sample 1, sample 2, which is consistent with the measured results of self-heating characteristics. Therefore, the nonlinearity method can be used to evaluate the self-heating tendency of sulfide ores, and it is an effective verification of the reliability of measured results.展开更多

Austen proclaims that feeling should be governed by reason in Sense and Sensibility and that reason should be compatible with feeling in Persuasion. This paper attempts to explore romantic tendency in Austen's works according to the comparison and contrast between her two novels. Through comparison and contrast, we can see the transformation of Marianne from a lady of sensibility to a sensible lady and the growth of Anne into a lady with romance.展开更多
