新兴和成熟产业中企业对学研方行为的演化博弈仿真分析

产学研合作对构建国家创新体系和实现向创新驱动型经济体转变具有重要的作用,而大力发展新兴产业是我国产业结构升级的必由之路。针对基于产业背景的产学研合作研究的不足,运用演化博弈理论比较分析两类产业中企业间随机两两配对与学研方开展合作RD的博弈过程,并采用Netlogo仿真软件对理论命题赋予相应的参数数值逐一进行验证。研究结果表明,无论何种产业,产学研合作的形成是一个逐渐演化的过程,并与合作成本呈负相关而与市场风险因子、合作收益呈正相关关系,在两类产业技术水平一定、合作创新收益相当的情况下,成熟产业中的企业更容易与学研机构开展合作。最后提出了改进新兴产业产学研合作现状的进一步思考。     

文化科技深度融合的关键影响要素分析

人类文明的进步和繁荣发展是伴随着科技创新而不断演进的。新时期,推进文化软实力和科技硬实力深度融合成为建设创新型国家和实现文化强国战略的重要途径。文化科技广泛而深入融合离不开对彼此依存、协调互动的多种影响因素分析和研究。从动力层、支撑层、政策指导层三个方面分析影响文化科技交汇融合的诸多因素,在此基础上引入解释结构模型(ISM)对文化科技深度融合的影响因素进行建模分析,明确各因素之间的相互关系,使文化科技融合影响因素之间错综复杂的关系条理化和层次化,为推进文化科技深度融合提供必要的理论依据。     

基于SCI数据库的国际食品安全研究现状与热点分析

采用文献计量学方法,以SCI数据库收录的2004-2013年食品安全研究期刊论文为数据源,对食品安全研究领域的高发文国家、机构、核心期刊、基金资助等情况进行定量分析;进一步利用社会网络分析法,构建高频关键词共现网络,探讨国际食品安全研究热点。研究结果显示,我国基金机构对食品安全研究的资助力度较高,但与欧美等发达国家拥有一些企业和企业家等机构进行科研资助的模式相比,资助来源相对单一;高频关键词网络连通性良好,"food"和"risk"是食品安全研究领域的中心点。     

绿色创新研究进展综述

围绕绿色创新领域的四个主要概念查阅文献、收集资料,按照企业、产业/行业、宏观经济三个层面对目前的研究主题及研究进展进行梳理,并在各层面依据其研究主题进行归类与评述,最后在分析现有研究不足的基础上提出未来研究的方向。     

基于信息生态视角的现代信息服务产业集群发展模式研究

针对现代信息服务产业集群发展存在的信息共享不足、信息流动不畅、协同机制缺乏等问题,从信息生态系统的视角考察其协同运营的机制与商业模式,以强化现代信息服务产业集群中的信息人、信息环境的整合、互动、共享和协同等机制为基础,构建一种基于信息生态系统观的现代信息服务产业集群协同创新发展模式的基本框架。这种以信息流为中心,将资金流、物流、业务流、价值流等集成一体化的协同模式,有利于提高这一产业集群中信息与知识的共享、开发与利用效能,强化价值创造、实现和共享的意愿和能力。通过实例表明,此模式为现代信息服务业的一体化协同创新发展提供了一种新的、可资借鉴的参考模式与实现途径,从而促进现代信息服务产业集群的健康可持续发展。     

细颗粒物(PM_(2.5))对农村环境空气质量评价的影响分析

为了评估细颗粒物(PM2.5)监测对农村空气质量等级的影响,2014年在3个村庄监测了二氧化硫(SO2)、二氧化氮(NO2)、吸入性颗粒(PM10)和细颗粒物(PM2.5)等污染指标,使用环境空气质量标准(GB 3095-2012)和环境空气质量指数(AQI)法进行评价。结果显示:农村环境空气质量评价等级在细颗粒物(PM2.5)纳入评估后有所降低,等级为优的比例从29.7%下降到1.7%,等级为良的比例从70.3%提高到95.0%,同时轻微污染的比例从0提高到3.3%。环境空气质量指数(AQI)法对空气污染物有了更准确的评价,能评估未超标情况下空气污染物对空气质量的贡献程度。PM2.5与PM10有显著的正相关关系。     

Calculating the Return on Investment (ROI) for Library Consortia

This column focuses on formal collaboration and networking among libraries through consortia. It offers in-depth examinations of issues facing modern library consortia including (but not limited to) e-resource licensing, ebooks, next generation integrated library systems, shared print archiving, shared digital repositories, governance and other relevant topics. Contributions are accepted for this column and must be submitted to George Machovec (george@coalliance.org). Contact the column editor for suggested topics, deadlines and formatting.

Library consortia are under increasing scrutiny regarding their value to member libraries. Most consortia offer a suite of services which can be valued either quantitatively or qualitatively to determine a return on investment for money and time put into consortial activities. Various common consortial activities are discussed with thoughts regarding their value to local libraries. Recommendations and suggestions are provided on how to perform a Cost Benefit Analysis (CBA)/Return on Investment (ROI).     

我国人文社会科学领域文献使用特征研究

[目的/意义] 分析各学科领域文献使用情况,可为图书馆开展信息资源采访工作和针对人才、机构等方面的科学评价工作提供数据支撑。[方法/过程] 以我国大陆地区主办的751种人文社会科学学术期刊为数据来源,以这些期刊在2004-2013年发表的131万篇论文为样本,以样本论文中著录的1 282万条参考文献为分析对象,对各学科文献使用情况进行分析。[结果/结论] 在人文社会科学领域,图书(34.03%)是使用率最高的文献类型,期刊使用率(33.95%)略低于图书使用率,其他类型文献使用率为32.02%。从学科角度看,人文学科学者偏爱使用图书,社会科学学者偏爱期刊,报纸和学位论文的使用学科差异性较小。从使用发展趋势来看,期刊、学位论文的使用率在逐年上升,图书使用率呈逐年下降趋势。     

A Systematic Review of Financial Literacy as a Termed Concept: More Questions Than Answers

Financial literacy, as a concept by that name, has only been explored in library science literature for a little over a decade. The concept, and especially the role of libraries in furthering this literacy, is still evolving. This systematic literature review examines the current definition of financial literacy, why financial literacy matters, where the public has been accessing financial literacy education to date, the difficulties encountered, by libraries and others, in providing this education, and how these challenges might be addressed moving forward.     

Hybrid Journals: Ensuring Systematic and Standard Discoverability of the Latest Open Access Articles

An important current challenge for research information providers is ensuring the automated discovery of Open Access (OA) content in hybrid journals. We found no evidence of discovery services that are able to systematically identify the crucially important free full-text availability of OA articles regardless of where and how such articles have been published (i.e., in fully OA journals or in hybrid journals). A solution is important because hybrid journals are proliferating and consequently the chances of missing OA articles is real and is happening. Nearly all of the major publishers now provide such journals in order to take advantage of recent changes in research funder requirements, and to be competitive in the new OA business model. By working with a group of scholarly publisher partners and by using standard metadata elements that publishers are already familiar with, we show a systematic and standardized manner to identify OA at the article level. Our proposal is to embed OA-related elements in the metadata freely exposed by publishers for aggregators and discovery services. For example, in the Table of Content (TOC) Really Simple Syndication feeds the publishers use to announce new journal issues and content. Based on the initial results obtained, we discuss the capabilities of our solution, and evaluate the impact produced by our application in the systematic discoverability of OA content from the participating hybrid journals, using an implementation done with the freely available journal current awareness service—JournalTOCs.
