The Use of Visual Tools in the Academic Research Process: A Literature Review     

Crystal Renfro 《The Journal of Academic Librarianship》2017,43(2):95-99

An academic librarian, especially one who works primarily in a research consultation capacity, often encounters individuals who are seeking in-depth help with research projects that they struggle to explain. The number of concepts, interdependencies and assumptions involved in research projects today can make them difficult to define and discuss with other people. The multidisciplinary nature and globalization of many areas of research is forcing researchers to not only discuss, but to collaborate with many others from different academic backgrounds and disparate physical locations. Many researchers struggle with project paralysis at various points along the way as they attempt to manage both the myriad of details and the bigger picture relationships and implications of their project.A number of visual tools including concept mappers and mind mappers are well suited to help advanced students, faculty, researchers and librarians to organize the ideas and knowledge throughout the various stages of complex research, from envisioning an idea to the early stages of actively researching and documenting research findings. This paper will discuss the potential uses of visual mapping tools and review the current state of academic literature surrounding the topics of mind mapping and concept mapping.  相似文献   

(Re)Viewing Reviews: Effects of Emotionality and Valence on Credibility Perceptions in Online Consumer Reviews     

Megan A. Vendemia 《Communication Research Reports》2017,34(3):230-238

This study examines credibility perceptions in online consumer reviews. Specifically, this work investigates the effects of review emotionality (high vs. low), review valence (positive vs. negative), and individuals’ need for affect on source credibility and information credibility. In an online experiment, U.S. adults (N = 327) viewed a product review from Amazon.com varied across four experimental conditions. Results indicate that high-emotionality reviews are perceived as lower in source and information credibility compared to low-emotionality reviews. A moderated mediation model was tested with the source credibility dimensions as possible mediators of information credibility and need for affect as a moderator for the effects of review emotionality. The effects of emotionality on information credibility were significantly mediated by source trustworthiness, and this mediation was moderated by participants’ need for affect, with the credibility-hampering effects of emotionality found only among participants with low and moderate levels of need for affect.  相似文献

Estimation of financial loss ratio for E-insurance: a quantitative model     

钟元生  陈德人  施敏华 《浙江大学学报(A卷英文版)》2002,3(2):140-147

In view of the risk of E-commerce and the response of the insurance industry to it, this paper is aimed at one important point of insurance, that is, estimation of financial loss ratio, which is one of the most difficult problems facing the E-insurance industry. This paper proposes a quantitative analyzing model for estimating E-insurance financial loss ratio. The model is based on gross income per enterprise and CSI/FBI computer crime and security survey. The analysis results presented are reasonable and valuable for both insurer and the insured and thus can be accepted by both of them. What we must point out is that according to our assumption, the financial loss ratio varied very little, 0.233% in 1999 and 0.236% in 2000 although there was much variation in the main data of the CSI/FBI survey.  相似文献   

基于作者署名排序的作者贡献要素分析——以《图书情报工作》2015-2016年作者贡献声明为例     

崔林蔚  陆颖 《图书情报工作》2017,61(9):80-86

[目的/意义] 以《图书情报工作》为例,探究作者贡献要素与作者署名排序的关系,为构建作者贡献声明规范提供借鉴,为基于文献内容的学术评价提供新方向。[方法/过程] 对《图书情报工作》作者贡献说明版块进行规范化标注,归纳出本学科的29位作者贡献要素,探究不同作者署名位置的作者贡献要素的规律,以及不同作者贡献要素在各个作者署名位置的分布情况。[结果/结论] 经过分析发现,第一作者起决定性作用,第二作者起贯穿性作用,第三和第四作者起辅助性作用,通讯作者起完善性作用;随着作者署名位置的降低,作者贡献越来越分散;越多参与撰写论文,署名排名也可能靠前。在此基础上,提出4点思考：作者贡献要素集中性较强,可制定词表进行规范化控制;贡献要素重要度差异较大,可赋予贡献要素不同权重;根据权重设置不同层次,建立贡献要素体系;挖掘论文中作者的实际贡献,助力学术评价。  相似文献

A multi-Agent system architecture for geographic information gathering     

高刚毅  王申康 《浙江大学学报(A卷英文版)》2004,5(11):1367-1373

World Wide Web(WWW)is a vast repository of information,including a great deal of geographic information.But the location and retrieval of geographic information will require a significant amount of time and effort. In addition,different users usually have different views and interests in the same information. To resolve such problems,this paper first proposed a model of geographic information gathering based on multi-Agent(MA)architecture. Then based on this model,we construct a prototype system with GML(Geography Markup Language). This system consists of three tiers-Client,Web Server and Data Resource. Finally,we expatiate on the process of Web Server.  相似文献
