在线信息产品捆绑定价研究

基于在线信息产品交易各方的互动关系,考虑网络接入商与信息产品生产商各自市场垄断力的对比,研究了两者进行价格决策的先后顺序对信息产品捆绑的最终价格和对信息产品厂商采用捆绑销售策略的影响.研究结果表明当两者同时进行价格决策时,两者均分市场利润;当两者进行序贯博弈时,先决策价格者将获得先动者优势,且消费者在此情形下的总支付将大于当两者同时决策时的总支付;信息产品厂商采用何种捆绑策略与其决策顺序无关,仅与被捆绑产品的捆绑价值参数相关.

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.

种内竞争对一年生植物高生长与生物量关系的影响

通过田间试验研究了两种一年生植物燕麦和箭She豌豆在高密度和低密度条件下表现出来的株高（H）与生物量（M）之间的异速生长关系，并用线性回归和非线性回归的方法对所得数据进行了分析，结果表明，植物在低密度条件下，个体间没有明显的竞争作用存在，株高与生物量之间表现为“简单的异速生长”关系，其异速生长表达式为y=a bx的形式；植物在高密度条件下，个体间存在着激烈的种内竞争，株高与生物量之间表现为“非线性的异速生长”关系，其异速生长表达式为y=ax^2 bx c的形式。
