凸算子的连续性及次可微性

本文研究了从赋范空间X到完备向量格赋范空间(Y,S)上的凸算子F的连续性及次可微性,给出了算子F 下半连续的一种新的局部性描述,将“下半连续的凸函数在其有效区域内部是连续的”推广到了凸算子上,并且证明了“凸算子F 在其有效区域内部某一开子集上序上有界,则F 在其有效区域内是局部Lipschitz 的”。在推广了Hahn-Banach 定理的基础上,证明了凸算子F 在其有效区域内是次可微的.

Who let the demon out? Laplace and Boscovich on determinism

In this paper, I compare Pierre-Simon Laplace's celebrated formulation of the principle of determinism in his 1814 Essai philosophique sur les probabilités with the formulation of the same principle offered by Roger Joseph Boscovich in his Theoria philosophiae naturalis, published 56 years earlier. This comparison discloses a striking general similarity between the two formulations of determinism as well as certain important differences. Regarding their similarities, both Boscovich's and Laplace's conceptions of determinism involve two mutually interdependent components—ontological and epistemic—and they are both intimately linked with the principles of causality and continuity. Regarding their differences, however, Boscovich's formulation of the principle of determinism turns out not only to be temporally prior to Laplace's but also—being founded on fewer metaphysical principles and more rooted in and elaborated by physical assumptions—to be more precise, complete and comprehensive than Laplace's somewhat parenthetical statement of the doctrine. A detailed analysis of these similarities and differences, so far missing in the literature on the history and philosophy of the concept of determinism, is the main goal of the present paper.

浅论中国民族体育传承的必要性

民族体育文化作为一个民族的文化组成部分，在民族的发展、文化的传承中占据着重要地位，当全球一体化席卷而来时，中西方文化相互碰撞、交融，西方体育文化借助奥运会的发展，已有全面取代民族体育的趋势，民族体育文化的传承面临严峻形势。本文通过资料文献法等研究方法．从历史演变、近代发展着重阐述中国民族体育文化面临的困境和传承的必要性。     

Philosophy in the trenches: from naturalized to experimental philosophy (of science)

Recent years have seen the development of an approach both to general philosophy and philosophy of science often referred to as ‘experimental philosophy’ or just ‘X-Phi’. Philosophers often make or presuppose empirical claims about how people would react to hypothetical cases, but their evidence for claims about what ‘we’ would say is usually very limited indeed. Philosophers of science have largely relied on their more or less intimate knowledge of their field of study to draw hypothetical conclusions about the state of scientific concepts and the nature of conceptual change in science. What they are lacking is some more objective quantitative data supporting their hypotheses. A growing number of philosophers (of science), along with a few psychologists and anthropologists, have tried to remedy this situation by designing experiments aimed at systematically exploring people’s reactions to philosophically important thought experiments or scientists’ use of their scientific concepts. Many of the results have been surprising and some of the conclusions drawn from them have been more than a bit provocative. This symposium attempts to provide a window into this new field of philosophical inquiry and to show how experimental philosophy provides crucial tools for the philosopher and encourages two-way interactions between scientists and philosophers.     

牛顿-莱布尼兹公式的推广

在一元函数中，被积函数在闭区间上连续是牛顿一莱布尼兹公式成立的重要条件。本文通过减弱该条件使牛顿一莱布尼兹公式得到推广，并给出了应用实例。同时，讨论了二重积分和曲线积分的牛顿一莱布尼兹公式。
