数字内容产品版权保护的演化博弈分析     

赵艳  王文举  倪渊 《图书情报工作》2019,63(2):43-51

[目的/意义]基于版权保护的演化博弈分析，有助于探究数字内容产品的原创主体对仿冒行为是否具有容忍度，以及不同仿冒水平下实施版权保护的策略选择，对规范数字内容产品市场主体行为具有一定指导意义。[方法/过程]首先借助演化博弈模型，分析原创主体与仿冒主体的利益演化过程，探究版权保护下原创主体对仿冒水平的容忍行为；然后通过细化博弈双方的利润函数模型，探究原创主体容忍度水平的决定因素。[结果/结论]原创主体对较小的仿冒水平存在一定的容忍度，对较高的仿冒水平零容忍。最大仿冒水平容忍度由仿冒交叉收益系数、收益模型常系数、产品研发成本系数和原创主体的产品研发努力水平倍数4个因素共同决定。  相似文献

试论南京国民政府对我国盐政主权的收回     

姚顺东 《哈尔滨学院学报》2004,25(5):44-47

南京国民政府成立后，在关税自主、恢复和保留盐务稽核所的同时，通过变更职权和对洋人任用的变更开始了收回我国盐政主权的活动。南京国民政府当时对我国盐政主权的收回活动，现在看来，具有一定的历史意义。  相似文献   

Environmentally-induced stone decay: the cumulative effects of crystallization–hydration cycles on a Lincolnshire oopelsparite limestone     

Belinda J. Colston  David S. Watt  Helen L. Munro   《Journal of Cultural Heritage》2001,2(4)

An investigation has been undertaken at St Andrew’s church, Walpole St Andrew, Norfolk, to establish the underlying causes of the observed stone decay to the upper parts of the six stone piers. The stone decay was first recorded in the early 1930s. The salt-contaminated masonry within the church has been shown to undergo severe salt decay during the summer, with little damage occurring over the winter months. The south aisle piers have been shown to decay 2.5 times faster than the north aisle piers. Although crystallization–hydration cycles have been identified, the rate of decay is at its greatest when the cycling is relatively infrequent. This was not the expected trend. Furthermore, it has been shown that during extended periods where the ambient relative humidity is less than 75%, the rate of decay reaches a maximum. It is the length of this ‘drying’ period that apparently has the greatest influence on the rate of decay and could explain the significant difference in the rate of decay between the south and north aisle piers. The results have serious implications for passive conservation, where it is often recommended to lower the ambient relative humidity to well below the equilibrium relative humidity of the salt contaminant, to avoid crystallization–hydration cycles. Since, at the time of building, the church was situated on the coast, it is possible that the sodium chloride contamination occurred during the building process (1440–1520), particularly since the area was prone to sea-flooding at this time. Alternatively, the salt could have been applied as a treatment during the general restoration of 1897. Whatever the source of the salt, it seems likely that the ambient environment was changed by the insertion of a sealed floor in 1897, which could account for the onset of the salt decay.  相似文献   

馆藏比照评估的量化指标及其应用分析   总被引：1，自引：0，他引：1  

万召侗  慎金花  李丽 《图书馆杂志》2008,27(6):20-23

类比测量误差理论,提出文献信息资源评估体系的绝对馆藏冗余、馆藏保障率、馆藏冗余率等三个量化指标,借以指导可持续发展馆藏的评估工作。作为一个应用实践,根据Ul-rich期刊分类标准,比照分析同济大学图书馆馆藏纸本和电子英文期刊品种数量的规模、相对占有份额和可持续发展空间等以上指标的整体分布规律。结果表明,同济馆藏外文期刊品种数量的总体走向趋于一指数分布,且可以划分为明显的分类区间,基本符合学校学科设置和发展规划,在保障传统特色和基础研究领域的前提下,照顾一些新兴边缘学科的馆藏建设。  相似文献   

宽严相济刑事政策的路径探寻     

陈伟 《十堰职业技术学院学报》2008,21(2):5-7

建构和谐社会已经成为我国当前的政治目标,和谐社会要求通过各种方法,包括法律手段,化解各种社会矛盾,疏通各种社会积弊,由此而达到社会的长治久安。体现了刑罚谦抑性与人道性的"宽严相济刑事政策",是正视社会稳定与犯罪增长关系后的理性与科学的现实回应,我们应该多方位、多途径、多视角地为实现这一目标而进行路径探寻。  相似文献   

Study on effect of segments erection tolerance and wedge-shaped segment on segment ring in shield tunnel     

CHEN Jun-sheng MO Hai-hong 《浙江大学学报(A卷英文版)》2006,7(11):1864-1869

INTRODUCTION Shield tunnel method has become the most pre- ferred method in city tunnel construction because of its excellent attributes: little effect on surrounding environment, fast and safe construction, outstanding performance in earthquake resistance, etc. (Zhang et al., 2004). In different shield tunnels, the arrangement and number of segments are different, but the whole assembling process is generally the same. The as- sembling process begins with A2P, then A1P, A3P, BP, CP, …  相似文献
