In 2003 the World Summit on Information Society made a call for measuring the state of Information Society (IS) building between countries. The purpose of the measuring was to assess and compare IS practices around the globe as well as share best practices. A number of measurement tools have since been developed, and a number of previously constructed tools have been employed to fulfil this goal. Even though many variations in terms of indicators have been employed, the construction of measurement tools is subject to certain limitations. One limitation is that they do not incorporate these indicators on the actual levels of Information and Communication Technology (ICT) usage off the country's stakeholders. This paper analyses the most currently used indices for measuring the state of Information Society building from the perspective of their constituent indicators. Based on the analysis, an alternative framework for IS measurement, addressing the important aspects of ICT usage quality, is developed based on data from the EU member states. By applying the framework on measuring of ICT usage quality at Romania, Cyprus and Estonia, the usefulness is tested positive, and the need to evaluate the actual levels of ICT usage for the purpose of better policy-making, while establishing an information society, is accentuated.  相似文献

Small businesses face numerous issues in regard to the management of their knowledge, including potential loss of knowledge due to high employee turnover and the willingness and ability of employees to share their knowledge. This case study examines two small ICT companies in Vietnam to determine how knowledge transfer was conducted with and without the use of ICT. A knowledge transfer framework for small businesses was used as a lens to analyse the results. The findings showed differences in knowledge transfer approaches in both cases. It was observed that employees whose jobs required less flexibility needed more explicit knowledge, but if their working procedures were more flexible they were more likely to need tacit knowledge. Tacit knowledge was mainly transferred by non-ICT methods, with explicit knowledge being transferred via a combination of methods. The cases differed in regard to the existence of knowledge transfer guidelines – as well as the willingness and ability of employees to share knowledge with others in the business. Both case businesses lacked appropriate measures to determine the level of success of knowledge transfer activities.  相似文献

通过回顾相关文献,对重要基础设施脆弱性评价的研究基础、研究背景、评价思路、评价体系框架、评价内容等几个方面的主要观点、成果和发展趋势进行分析和总结。重要基础设施脆弱性评价以系统脆弱性分析为基础,是在识别出威胁的基础上对于系统要素和系统整体失效模式的分析,它是开展风险评价的重要组成部分。随着对基础设施系统分析的深入,评价思路逐渐成熟,即基于对系统进行"系统-子系统-要素"的分解,通过对每一环节所面临的威胁情景进行分析,进而对要素受损可能性进行判断,最终通过打分实现对脆弱性的定量评价。从评价体系框架的形成来看,主要可以分为"空间"到"时间"和从"物质"到"社会"两条路径,并且由于两条路径的不断交叉融合,形成了包含四个维度的评价体系框架,而目前的评价内容正是由此细化而来。评价内容主要涉及了地质条件与衰变、设施的报废与更新、地理位置与内部结构、相关性、中断威胁、政策与政治环境、保护与保障措施、容量与可用性八个方面。  相似文献

This JLA column posits that academic libraries and their services are dominated by information technologies, and that the success of librarians and professional staff is contingent on their ability to thrive in this technology-rich environment. The column will appear in odd-numbered issues of the journal, and will delve into all aspects of library-related information technologies and knowledge management used to connect users to information resources, including data preparation, discovery, delivery and preservation. Prospective authors are invited to submit articles for this column to the editor at kenning.arlitsch@montana.edu.

The cost of building library collections continues to increase, forcing librarians to think differently about their budget models. Increasing costs of IT infrastructure needed to connect to information resources also adds to budget concerns. The idea of changing the emphasis of collections budgets to one of broader access is not new, but formally acknowledging the need to support local technology infrastructure and other means of access may offer a new way of promoting the collections budget to university administrators. We propose a budget model that acknowledges these broader requirements and includes concepts of surfacing and discovery, provision, creation, and acquisition.  相似文献

Focusing on the process of “technology transfer”, this paper aims to critically examine the production and usage of the information and communication technology (ICT) curriculum, and discusses its possibilities. It is found that the goals in both of the two stages of the ICT curriculum in Taiwan were rather “rhetorical”. Three problems are then discussed: an “inevitable” discourse, but opposed to its original intention, the exclusion of instructional issues, and the exclusion of students' life experience and reflection. Finally, three possibilities for the ICT curriculum are proposed: expanding educators' understanding of the ICT curriculum, developing an ICT curriculum beyond the dominance of ICT experts, and rethinking the role of teachers in the implementation of the curriculum.  相似文献

1999年开始的大学扩招进程中,普通高等学校面临“基础设施效用不彰”的问题。以学生类校舍的生均面积及其“标杆值”为基础,以各学生类校舍的“效用偏差”为分析对象,采用熵值法测算了八类校舍“效用偏差”的权重,评价了扩招以来各年度学生类校舍的效用总偏差。研究发现:八种学生类校舍的“效用偏差”可以区分为“保健型”指标、“激励型”指标和“中间型”指标三种类型;扩招以来的学生类校舍综合效用处于“不彰”甚至一定程度的“倒退”状态。研究结论是:第一,政府对普通高校基础设施缺乏有力的宏观调控;第二,普通高校打了一场后勤保障投入失当的“扩招之战”但面临提高学生类校舍综合效用的“重要机遇期”;第三,普通高校具有实现组织利益最大化的倾向;第四,普通高校在基础设施供给方面体现了“赶牛式”行政的特征,且形成了一定程度的“投入惯性效应”。  相似文献

以ICT行业为例,实证分析企业在不同规模下专利进攻战略和防御战略对专利质量的影响.研究发现,对于大、小规模的企业,采取进攻战略会正向影响专利质量,采取防御战略则无影响;对于中规模的企业,采取防御战略会负向影响专利质量,采取进攻战略则无影响.研究为不同规模的企业提升专利质量提供战略决策层面的理论依据.  相似文献
