图书馆馆员应具备的职业素质

图书馆是人类智慧的宝库，信息资源的源头。其工作人员不仅是图书资料的保管员，读者借阅的服务员，还是信息资料的收集员、整理员、传播员、自动化管理的操作员。因此，图书馆工作人员(以下简称馆员)应具备较高的综合素质。要适应新世纪变革的要求，作为知识和信息资源载体的图书馆，不仅馆舍、设备要改善，管理人员也要适应新时代的要求。然而，目前图书馆员的状况却不容乐观。

读书与著述

浏览一些古今学者有关读书与著述的言论,可以看到两种好似矛盾的倾向。一方主张慎写特别是慎发表,如黄侃重基本功,告诫学生30岁以前不要轻易在报刊上发表文字,他自己更是声明“五十岁以前不著书”。另一方主张勤写多写,朱光潜介绍过自己边读边写的治学方法,认为带有研究问题地读,可以读的更认真、精细。任凯南对学生说,你们在30岁以前,应该大胆发表一点东西,好坏没有关系;不然的话,过了30岁就难得有勇气拿出自己的东西了。他自己就终生没有出过一本著作。     

Beyond anti-terrorism: Metaphors as message strategy of post-September-11 U.S. public diplomacy

This research analyzed the major metaphors the U.S. government created to define the post-September-11 world realities, including “Second Front,” “Axis of Evil,” “Old Europe,” “Responsible Stakeholder,” and “Color Revolution.” The metaphors are found to be rhetorically advocating and share the archetypal metaphor of “democracy vs. tyranny” and “freedom vs. oppression.” The metaphors had their origins in the U.S. national security strategies, and the images they created highlighted aspects of the moral and ideological considerations but hide certain aspects of the realpolitik motivations.

小波分析法在变速机械故障诊断中的应用

首先利用小波分析将非平稳随机信号进行分解，然后再由Ｆｏｕｒｉｅｒ变换对分解后的信号进行频谱分析，最终根据各频谱特征，实现对变速机械的故障诊断．以某冷轧厂新增３５００ｔ／ｈ大型冷却塔用变速及冷却系统的故障诊断为例，验证了本文提出的用小波分析对变速系统进行故障诊断的有效性

Weighing the Evidence for Hypotheses with Small Samples of Right-censored Exponential Data

The p-value evidence for an alternative to a null hypothesis regarding the mean lifetime can be unreliable if based on asymptotic approximations when there is only a small sample of right-censored exponential data. However, a guarded weight of evidence for the alternative can always be obtained without approximation, no matter how small the sample, and has some other advantages over p-values. Weights of evidence are defined as estimators of 0 when the null hypothesis is true and 1 when the alternative is true, and they are judged on the basis of the ensuing risks, where risk is mean squared error of estimation. The evidence is guarded in that a preassigned bound is placed on the risk under the hypothesis. Practical suggestions are given for choosing the bound and for interpreting the magnitude of the weight of evidence. Acceptability profiles are obtained by inversion of a family of guarded weights of evidence for two-sided alternatives to point hypotheses, just as confidence intervals are obtained from tests; these profiles are arguably more informative than confidence intervals, and are easily determined for any level and any sample size, however small. They can help understand the effects of different amounts of censoring. They are found for several small size data sets, including a sample of size 12 for post-operative cancer patients. Both singly Type I and Type II censored examples are included. An examination of the risk functions of these guarded weights of evidence suggests that if the censoring time is of the same magnitude as the mean lifetime, or larger, then the risks in using a guarded weight of evidence based on a likelihood ratio are not much larger than they would be if the parameter were known.
