AbstractWhether to use a classified or alphabetical arrangement of print periodicals is still a controversial issue in academic libraries. Both systems provide access for patrons, and each has its strengths and weaknesses. Proponents of alphabetical arrangement emphasize ease of use for the patron. The primary argument for classification focuses on the patronâ€?s browsing ability. However, there are other factors involved in choice of arrangement. Bibliographic control, collection size, and physical constraints are often important considerations in deciding which system provides optimal access for library patrons. 相似文献

The misuse of statistics at Sally Clark's trial hadprofound consequences, especially for her, but also for the subsequent cases. Ray Hill reflects on the statistical issues involved. 相似文献

艺术品证券化的风险分析与现实反思 总被引:1,自引:0,他引:1
从艺术品证券化发展历程中的特点可以看出艺术品证券化模式是一把“双刃剑”,从实证分析中可以看出它的收益与系统性风险呈负相关关系,违背了“高风险高收益”的基本投资原则,不存在CAPM所设想的系统性风险与收益之间的显著线性相关关系,说明中国艺术品证券投资市场是一个不成熟不健全的投资市场.目前艺术品证券化模式已经被叫停,因此有必要对这种模式进行反思总结,并探索一条适合中国艺术品投资实际的新路子. 相似文献
