论中国古代藏书楼的文化意义

藏书楼是藏书活动的建筑载体,是我国传统文化的重要标志之一。中国古代藏书楼在其命名、建筑设计、空间布局和环境建设等方面独具特征,而这些特征的产生既有主观原因,也有客观原因。藏书楼对我国传统文化的传承和保护起到了重要作用,应该对现存藏书楼加以大力保护。

Diversity in the Information Seeking Behaviour of the Virtual Scholar: Institutional Comparisons

The logs of four universities using the OhioLINK journal system were evaluated for a period of fifteen months using deep log analysis methods in order to compare and contrast the information seeking behaviour of their users. Large differences were found, especially between the research and teaching universities. Methodological problems associated with making the comparisons are discussed in some detail especially in terms of defining online sessions.

Effects of contextual cues previously paired with footshock or illness on behavior and pain sensitivity in the rat

Rats were used in four experiments to study the effects on behavior and pain sensitivity of exposure to a context previously paired with footshock or injection of the emetic drug lithium chloride (LiCl). Exposure to a context previously paired with footshock or injection of LiCl provoked the species-typical defense response of freezing (Experiments 1A and 1B). Exposure to a context previously paired with footshock additionally produced hypoalgesia when rats were tested using the tailflick test (Experiment 1A). By contrast, exposure to a context previously paired with injection of LiCl produced hyperalgesia when rats were tested using the tailflick test (Experiment 1B). However, exposure to a context previously paired with injection of LiCl did provoke hypoalgesia when rats were tested for pain sensitivity using either the hotplate or formalin tests (Experiment 2), which was mediated by the release of endogenous opioid peptides (Experiment 3). These results are discussed with reference to the processes governing associative regulation of defensive behavior and pain control.     

Representing How Rabbits Quack and Competitors Act: Limits on Preschoolers' Efficient Ability to Track Perspective

This study investigated whether humans have two mind‐reading systems whereby the efficient system, unlike the flexible system, is naturally limited. There were two experiments and the first included adults as well as children (3‐ to 4‐year‐olds; total N = 128). In Experiment 1, all groups efficiently gazed in anticipation of an agent's beliefs about object location but not object identity (an ambiguous figure). In Experiment 2, children showed limits in anticipating a competitive agent's action in terms of his perspective on what is desirable. Flexibility in verbally predicting agents' actions across contexts developed with age. Convergence on signature limits across different ages and methods suggests that indirect anticipations involve minimal mind reading, whereas direct predictions tap a refined understanding of perspective.

关于利用"出版号"作书次号的探讨--兼与蒋鸿标先生商榷

"出版号"即出版者代号+出版物的流水号(即书名号),它是中国标准书号的一部分,按序排列,形成一个恒寂的8位数.这个编码系统科学性强,且具唯一性.利用它作书次号排架,乱架率可达零;索书,漏检率可达零;组织目录,款目错位率适可达零.
