高校二级学院档案管理模式探析

目前，我国高校普遍实行校院二级管理的模式，档案的管理也应与之相匹配。文章在探讨高校二级学院档案管理的任务和内容基础上，分析了目前高校二级学院档案管理存在的文件材料散乱、管理手段落后、机构设置不健全等问题，通过对高校二级学院档案管理实行分级管理模式的基本原则、基础保障等方面的探析，最后提出了二级学院档案实行分级管理的有效手段具体建议。     

Search on surfaces: Exploring the potential of interactive tabletops for collaborative search tasks

Collaborative information seeking often takes place in co-located settings; such opportunities may be planned (business colleagues meeting in a conference room or students working together in a library) or spontaneous (family members gathered in their living room or friends meeting at a café). Surface computing technologies (i.e., interactive tabletops) hold great potential for enhancing collaborative information seeking activities. Such devices provide engaging direct manipulation interactions, facilitate awareness of collaborators’ activities, and afford spatial organization of content. However, current tabletop technologies also present several challenges that creators of collaborative information seeking system must account for in their designs. In this article, we explore the design space for collaborative search systems on interactive tabletops, discussing the benefits and challenges of creating search applications for these devices. We discuss how features of our tabletop search prototypes TeamSearch, FourBySix Search, Cambiera, and WeSearch, illustrate different aspects of this design space.

Toward multimodal inquiry: opportunities,challenges and implications of multimodality for research and scholarship

In this article, we suggest that we are witnessing a challenge to the hegemony of text-based knowledge in academic scholarship, brought about by newly available modes of expression, and a cultural shift in our notions of reading and writing, authorship, and networked knowledge production. The central question we address here concerns the implications of widening our ideas of acceptable forms of inquiry, analysis and representation in academic scholarship. As a collective of scholar-practitioners exploring new modes of expression and working both within and outside the formal structures of academia, we argue for the increasing significance of multimodal research in the contemporary context of academic inquiry. By more equitably valuing different ways of thinking, knowing and communicating, multimodal research can facilitate wider and more diverse participation in the production of knowledge, offer a more nuanced and ethical mode of inquiry, emphasize different ways of knowing and connecting, and make scholarship more broadly accessible beyond academic contexts. Here, we analyze the key opportunities facilitated by multimodal inquiry, as well as the obstacles that stand in the way of a wider adoption of this type of research in higher education.     

基于差异性视角的期刊区分性测度及分析研究

当前的期刊评价研究主要集中在影响力、声誉、质量等方面,针对期刊内容差异性的定量研究相对较少。本文从差异性视角来对期刊进行评价分析,提出期刊区分度指标来对期刊内容的差异程度进行度量。以LIS (library and information science)等5个学科的各20种核心期刊为研究对象,首先对LIS期刊的内容差异性进行定量分析与评价,然后从时间维度对LIS学科期刊区分度的变化规律进行了探测,最后从学科维度对不同学科期刊个体和总体区分度的特征进行了分析和探讨。实验结果表明,利用该指标能够很好地度量期刊研究内容差异性,期刊区分度在时间维度上呈现出明显的变化规律,不同学科期刊个体和总体的区分度均具有显著的学科特征。     

Hierarchical self-localization of underwater wireless sensor network nodes

The follow-up application of underwater wireless sensor network is influenced by accuracy of self-localization of nodes. The self-localization of nodes is discussed in this paper. First of all, nodes of underwater wireless sensor network are classified into several levels according to the accuracy of position of nodes and the levels are from the first to the fifth in accordance with accuracy of nodes from high to low respectively. Secondly, the level of anchor nodes can be known by those unknown nodes from the information given by the anchor nodes themselves, At the same time the unknown nodes are able to be located in the area controlled by the first level of anchor nodes that are as the aggregation. Then the positioning algorithm is designed correspondingly in accordance with the accuracy level of nodes. Finally, the positioning algorithm is simulated and analyzed. The result shows that the unknown nodes can be located effectively by hierarchical control.
