网络证据之形式问题研究

网络证据能够用来证明待证事实的原因在于其蕴含了该待证事实留下的事实信息。网络证据的存在形式由网络信息的获取及固定方式决定。只有保证其获取信息和固定信息方式的合理性,网络证据在形式上才具有作为证据的适格性。作为一种独立证据形式的网络证据,其划分应当以网络证据蕴含的信息内容及其固定方式为标准。     

信息生命周期管理在数字图书馆中的应用

信息生命周期管理是近两年倍受关注的热门课题,在我国尚处于萌芽阶段。文章在简单介绍信息生命周期管理(ILM)概念的基础上,针对数字图书馆及网络存储中信息数据过量以及信息时效等管理问题,提出一种信息生命周期管理模式。     

Dispersing the Serials Collection and Measuring Paper: Cooperative Storage Efforts and Legacy Journals Management in a University Library

This article discusses workflows involved with contributing print journal back runs to scanning and storage efforts. The purpose of these efforts was to alleviate space problems in a library by consolidating stacks that were formerly used to house runs of bound journals. This article contributes to the literature on serials withdrawal projects by demonstrating database designs for tracking contributions made to cooperative storage facilities as well as highlighting an innovative solution for tracking the required linear feet for housing bound print collections.

自动化立体仓库中货位实时分配优化问题研究

本文研究了单元货格式自动化立体仓库中的货位实时分配问题。该问题可分为两方面：为入库分配空货位和为出库选择货位。在考虑了堆垛机的加减速对其运行速度的影响后,以堆垛机将要进行的所有操作的行程时间之和作为优化目标,通过调整堆垛机的后续操作的行程时间在总行程时间中的权重,依次构建了三个优化目标函数。然后利用结合了模拟退火方法的遗传算法对其进行了求解,并利用了多种技术提高算法的效率。最后利用仿真技术,通过改变仿真时系统中的货物类型总数、堆垛机的停留策略和装载能力,对该算法在不同情况下的效果进行了验证。仿真结果表明在不同情况下,该算法都可不同程度地减少堆垛机的平均行程时间。     

Ethical ‘mess’ in co-produced research: reflections from a U.K.-based case study

Co-producing research is complex and messy. This paper draws on Tina Cook’s argument for the systematic inclusion of ‘mess’ in research accounts as a conceptual framework through which to articulate areas of ethical mess from within a co-produced research project. Through narrating the ‘messy’ ethical complications the paper illustrates a number of specific ethical risks when co-producing research; particularly when working with young people. The paper provides valuable insight into ethical tensions that can emerge when using a co-produced methodology and will be informative for future researchers negotiating their own co-produced research projects. The paper argues for the systematic inclusion of mess in the accounting of participatory research.

The 5K Run Toolkit: A Quick,Painless, and Thoughtful Approach to Managing Print Journal Backruns

Abstract

Increasingly, academic libraries are choosing to discard or place in storage print journals that are now available online. The identification of these titles and related collection analysis activities are often time-intensive. The approach at the University of Saskatchewan Library was to develop an online toolkit that combined available data from disparate sources including the integrated library system, SFX link resolver, and OCLC's WorldCat and then present them in a collaborative open source environment. This paper demonstrates how the careful combination of existing data presented in a simple online format allowed subject specialists to make accurate print journal deselection decisions quickly and painlessly.     

Numerical computation of bridge probabilities

This paper contains an analysis of the problem of computing the joint probability density of the honor card point count in each of four hands in the game of bridge. Efficient representation of the data is considered. Computational algorithms are given for dealing with a compressed form of the density. From the joint density, the densities of the point count in the best and worst hands are obtained. Also obtained is the conditional distribution that a partnership has m points given that one of the partners has n1 points.     

利用储存器计算非连续结构

非连续结构指的是某些意义上完整但句法表现上却断裂的语言成分。非连续结构虽然结构特殊,但在自然语言中具有普遍性。普通的移进、归约方法在计算非连续成分时是无效的。尽管范畴逻辑语法提出了一些办法,但是未能对非连续现象进行统一的处理。实际上,语义上的计算步骤不一定要严格对应句法操作,Cooper储存是这样一种典型的方法。它不但可以用来处理广义量词的计算问题,也可以在稍加改造后用来处理一般非连续结构。这里提出了一种吸收Cooper储存的基于LR方法的计算方法:它使用了一个监视句法分析流程的装置,并要求对非连续成分进行分类和标注。这种方法的好处是完全不用更动传统的句法分析。
