Philosophy of chemistry and the image of science

The philosophical analysis of chemistry has advanced at such a pace during the last dozen years that the existence of philosophy of chemistry as an autonomous discipline cannot be doubted any more. The present paper will attempt to analyse the experience of philosophy of chemistry at the, so to say, meta-level. Philosophers of chemistry have especially stressed that all sciences need not be similar to physics. They have tried to argue for chemistry as its own type of science and for a pluralistic understanding of science in general. However, when stressing the specific character of chemistry, philosophers do not always analyse the question ‘What is science?’ theoretically. It is obvious that a ‘monistic’ understanding of science should not be based simply on physics as the epitome of science, regarding it as a historical accident that physics has obtained this status. The author’s point is that the philosophical and methodological image of science should not be chosen arbitrarily; instead, it should be theoretically elaborated as an idealization (theoretical model) substantiated on the historical practice of science. It is argued that although physics has, in a sense, justifiably obtained the status of a paradigm of science, chemistry, which is not simply a physical science, but a discipline with a dual character, is also relevant for elaborating a theoretical model of science. The theoretical model of science is a good tool for examining various issues in philosophy of chemistry as well as in philosophy of science or science studies generally.     

A Critical Review of "Rethinking Task-Based Language Learning:what we can learn from the learners"

This paper will critically review an academic article titled "Rethinking task-based language learning: what we can learn from the learners" which was written by Assia Slimani-Rolls from European Business School London and published in Language Teaching Research 9,2 (2005). On one hand, there is of no denying that the article has the significance in carrying out the study--- it arouses people's attention to learner idiosyncrasy and learner perception of tasks while other most researchers just pointed out the importance and necessity of task-based teaching and advocated the effectiveness of CAs. On the other hand, there are still some problems existing in the study, from the research design to its analysis. The author will analyze them one by one and give her own understanding along with it.     

ROLE OF α-PSEUDO-UNIVEX FUNCTIONS IN VECTOR VARIATIONAL-LIKE INEQUALITY PROBLEMS

In this paper, we introduce a new class of generalized convex function, namely, a-pseudounivex function, by combining the concepts of pseudo-univex and α-invex functions. Further, we establish some relationships between vector variational-like inequality problems and vector optimization problems under the assumptions of α-pseudo-univex functions. Results obtained in this paper present a refinement and improvement of previously known results.

科学技术的环境价值探悉

科学技术以其特有的生态功能而蕴涵着巨大的环境价值，其广泛的应用却出现了对环境价值追采的背离。需要探析其深刻的认识论原因和社会原因，通过转变科学范式，确立科技创新的生态导向，为人与自然的积极平衡提供技术支撑，以实现科学技术社会环境价值的回归。处于人与自然矛盾之中和市场经济压力之下，推进科技创新，改变科技落后状态是硬道理，是时代赋予我们的使命。
