基于高校网站的社会网络分析与评价的相关性探究     

金晓耕  孙建军 《现代情报》2014,34(9):51-55

本文首先对链接分析领域的社会网络研究现状进行了简要的概括,然后从泰晤士高等教育2013年世界大学排名中选取了排名前30位的高校,根据高校网站间的相互链接数量建立多值有向网络,然后通过Ucinet软件对其进行社会网络分析。将分析得到的社会网络指标以及根据链接数量计算的距离与高校的排名、总评分及各个一级指标的评分进行了相关分析,分析发现高校网站的总距离S和入度总距离SI均与高校的论文引用指标呈现显著的负相关性。  相似文献   

近红外光谱分析原理、检测及定标技术简介     

高红秀  金萍  周玉岩  石瑛 《中国科技信息》2014,(3):59-61

近年来,近红外光谱技术以其独特的优越性越来越受到人们的关注,已成为发展最快、最引人注目的分析技术之一.近红外光谱技术对样品的分析要通过校正模型的建立来实现,实验结果的准确性与定标模型的可靠性有直接的关系,所以如何建立一个准确、可靠的定标模型在近红外光谱技术使用中至关重要.  相似文献

国内外网络舆情数学建模研究综述     

苏创  彭锦  李圣国 《情报杂志》2014,(10)

互联网技术的发展及网络应用的普及使网络舆情成为当前一个热门的研究领域。众多学者从不同角度运用不同的数学方法对网络舆情进行了研究,取得了大量成果,涌现出大批文献。本文从数学建模的视角对部分国内外网络舆情的研究文献进行归类分析。按照网络舆情中不确定性因素的数学处理方法不同,将网络舆情数学建模的模型主要分为四类。即经典数学模型、随机数学模型、不确定数学模型、其它数学模型。结合现有网络舆情数学建模中存在的问题,本文对网络舆情相关研究的未来发展趋势进行了展望。  相似文献   

创新生态系统:源起、知识演进和理论框架     

梅亮  陈劲  刘洋 《科学学研究》2014,32(12)

创新驱动发展的背景下,企业竞争优势的提升越来越依赖其所处的创新生态系统。作为市场与组织的中间层次,生态系统视角成为创新理论研究范式的新方向。现有的研究缺乏对于创新生态系统理论及其研究演进的系统性回顾。本文以科学计量方法为基础,系统论述了创新生态系统理论的源起、知识演进和理论框架。研究结论显示:创新生态系统的理论研究主要围绕商业生态系统,价值创造,开放式创新,创新生态系统四大聚类展开。基于重点文献对创新生态系统理论知识演进的分析,创新生态系统的理论框架可分为核心文献、理论基础、研究方法三大层次。  相似文献   

Green intellectual capital and environmental product innovation: the mediating role of green social capital     

Miriam Delgado-Verde  Javier Amores-Salvadó  Gregorio Martín-de Castro  José Emilio Navas-López 《知识管理研究与实践》2014,12(3):261-275

Although the importance of intellectual capital has already been highlighted in the management literature, few articles have focused on the importance of its green counterpart, green intellectual capital. Nowadays, when environmental concerns cannot be ignored by firms, it is therefore time to explore the role of green intellectual capital in environmental improvement. For that reason, our research aims to explore the relationships between green intellectual capital components and the environmental performance of the firms. In particular, we try to show the importance of green organizational and social capital in the development of environmental product innovations, which are vital to the development and implementation of environmental strategies since, as scholars have pointed out, they generate some of the greatest environmental impacts. The empirical results show that green organizational capital has an indirect impact on environmental product innovation through green social capital, meaning that the latter is a significant mediator of that relationship, and at the same time emphasizing that informal relationships play a key role in the improvement of the environmental performance of the firm and, more specifically, in the development of environmental product innovations.  相似文献   

Learning,innovation and firm performance: knowledge management in small firms     

Banjo Roxas  Martina Battisti  David Deakins 《知识管理研究与实践》2014,12(4):443-453

This study aims to examine the relationships between managerial learning as a facet of knowledge absorption (KA), firm innovation as a facet of knowledge exploitation (KE), and performance of small firms (i.e., firms with fewer than 50 employees). It builds on the knowledge-based view of the firm and the upper echelons theory to describe the effects of KA on KE, and that of KE on firm performance, in the small-firm context. Using survey data of 1441 small firms in New Zealand, the study applies a partial least squares approach to structural equation modelling to test the main hypotheses of the study. The main findings show the positive and significant effects of three types of managerial learning, namely, practice-based, proximal, and distal learning, on innovation and on innovation in firm performance. However, the curvilinear relationships suggest rather that the effects are finite and, potentially, confounded by factors unaccounted for in the models.  相似文献   

Enabling integrated knowledge acquisition and management in health care teams     

Duncan Pentland  Kirsty Forsyth  Donald Maciver  Mike Walsh  Richard Murray  Linda Irvine 《知识管理研究与实践》2014,12(4):362-374

Basing treatment, policy and planning decisions on the best available research knowledge remains a central principle in modern health care around the world, yet many health professionals find acquiring and managing published research knowledge challenging. In this paper, we report on a Soft Systems Methodology-based collaborative action research initiative with a specialist mental health service from the United Kingdom's National Health Service. Our objective was to design and implement improvements to their knowledge acquisition and management activities in order to facilitate sustained and effective evidence-based practices. We report on both the factors found to impede effective research knowledge acquisition and management and the development of more integrated knowledge management processes designed to improve the situation.  相似文献   

The impact of workforce agility on organizational memory     

Abeer Hmoud Al-Faouri  Marwan Mohammed Al-Nsour  Mohammed Mufaddy Al-Kasasbeh 《知识管理研究与实践》2014,12(4):432-442

Existing literature has generally focused on organizational memory (OM) and workforce agility. Yet, less concentration has been devoted to the impact of workforce agility on OM. This research proposed a model that studies the impact of workforce agility on declarative OM and procedural OM. The model focused on aspects related to proactivity, adaptability, and resiliency. The study targeted the cell phone industry in Jordan. The study sample included 430 individuals involved in managerial and professional knowledge positions in mobile communications companies in Jordan. The article concluded that a proactive workforce has a significant impact on declarative OM and proactivity also improves procedural OM. Consequently, practical implications for managers, and suggested future research are presented.  相似文献
