大学图书馆的绩效评估

文章简要介绍了绩效评估的基本方法,指出大学图书馆实行绩效评估是时代发展的需要,是引入竞争机制的具体体现。文章强调大学图书馆工作的绩效评估要以“工作规范为基础”,要引入等级记分法,用等级和分数来代替评语,要赋予每一项考核内容明确的数量值,以使评估人员在操作过程中便于检查、统计、比较。     

Analyzing imbalance among homogeneous index servers in a web search system

The performance of parallel query processing in a cluster of index servers is crucial for modern web search systems. In such a scenario, the response time basically depends on the execution time of the slowest server to generate a partial ranked answer. Previous approaches investigate performance issues in this context using simulation, analytical modeling, experimentation, or a combination of them. Nevertheless, these approaches simply assume balanced execution times among homogeneous servers (by uniformly distributing the document collection among them, for instance)—a scenario that we did not observe in our experimentation. On the contrary, we found that even with a balanced distribution of the document collection among index servers, correlations between the frequency of a term in the query log and the size of its corresponding inverted list lead to imbalances in query execution times at these same servers, because these correlations affect disk caching behavior. Further, the relative sizes of the main memory at each server (with regard to disk space usage) and the number of servers participating in the parallel query processing also affect imbalance of local query execution times. These are relevant findings that have not been reported before and that, we understand, are of interest to the research community.     

家庭支持网与农村空巢家庭养老问题

从乡土资源与现代社会保障视角看,家庭支持网在解决农村空巢家庭养老问题中发挥了极为重要但又相对有限的作用,其在农村空巢家庭养老中的角色需要进一步发掘。借助政府公共力量的投入重新发掘这一乡土资源,强化农村社区互助养老模式可为农村空巢家庭养老问题的缓解开辟新的途径。     

引导高校合理竞争 完善自主招生制度

在资源分配行政划拨和高等教育资源供不应求的卖方市场环境下,我国高校之间长期以来缺乏竞争。自主招生为高校之间争夺优质生源提供了竞争平台,提供了完善高校竞争机制的切入点。在竞争的压力下,各高校才有动力不断提高自身的办学条件,提高教学科研水平,不断改进教学内容以适应社会需求,形成多样化和特色化的人才培养方案。管理部门应该给予学校足够的自主权,并给予政策上的引导和支持,以自主招生为切入点,完善高校竞争机制,提高高校的综合实力。     

Resistance partial factor and reliability of cast ball-and-socket support joint

Considering the uncertainty of material performance, geometric characteristic and analysis method, the analysis of statistical parameters of the resistance of cast ball-and-socket support joints and the reliability analysis are carried out by JC method (improved first-order second-moment method) based on the relevant experimental data. Results show that the resistance partial factor of the joint increases with the increase of the reliability index. The resistance partial factors are suggested corresponding to the reliability index under different load combinations. Moreover, the suggested resistance partial factor is adopted in reliability design, and it is found that the reliability index of the joint is larger than the target reliability index. The optimal load combination is the one in which live load plays an important control role. Finally, based on the suggested resistance partial factors, the reliability analysis of cast ball-and-socket support joints of a project is conducted.
