数字出版基地的内涵及界定

建设数字出版基地是政府倡导的发展数字出版产业的重要模式,并在各地掀起了建设数字出版基地的热潮。由于国家没有对数字出版基地做出权威的界定,各地又缺乏统一的认识,导致在数字出版基地建设实践中出现了诸多问题。本文以数字出版的定义为基础,研究数字出版产业的构成,进而探讨数字出版基地的内涵,认为数字出版基地是数字出版产业集群化发展的一种表现形式和高级阶段,并对数字出版基地做出了界定,形成了较为完整的数字出版基地的概念。     

大型文学刊物《文聚》形式考述

抗战时期昆明的文学刊物《文聚》是西南联大学生林元主创的。《文聚》有着自己的形式特征,刊名、开本、刊期、目录、编后、出版时间和版权页等“版形”同少异多,不可“举一反三”;稿约和广告等“附载”有同有异,反映出文聚社的外部关系,不能“知一而足”;目录与正文的排列显示出《文聚》高超的编辑艺术,值得研究学习。在研究者很难见全《文聚》杂志的情况下,文后还附录了《文聚》各期的目录。     

知识互动共享与企业簇群的创新优势

企业簇群的创新优势源于知识互动共享 ,企业在地域空间上的集聚和分工协作有助于企业间的知识共享 ,簇群内企业与簇群外企业相比更容易分享产业默会知识。所以 ,企业簇群化有利于创新。     

数据挖掘中一种新的聚类方法——基于对应分析与因子旋转

内容提要：本文基于Q型因子分析的基本思想,结合对应分析方法,建立了一种适用于大型数据库聚类的方法。该方法既解决了Q型因子分析算法效率方面的问题,也解决了传统对应分析法中缺乏客观分类标准、信息损失严重等多种缺陷,在实证分析中也取得了良好的效果。

生活质量是城市价值的核心,是一个多层面的复合概念。本文在宏观层次上综合出一套以客观指标构成的生活质量综合评价指标体系。从经济生活、社会保障、教育文化、生命健康、生活环境和交通通讯六个层面来衡量浙江省11个城市的居民生活质量状况．并运用聚类分析、方差分析等技术对各个城市生活质量的区域差异进行了比较研究．最后对如何提高城市居民的生活质量提出了一些建议。     

Investigating Regional Disparities of China’s Human Development with Cluster Analysis: A Historical Perspective

This paper adopts both one-dimensional and multi-dimensional cluster analysis to analyze China’s HDI data for 1982, 1995, 1999, and 2003, and to classify China’s provinces into four tiers based on the three basic developmental aspects embedded in HDI. The classifications by cluster analysis depends on the observations’ similarities with respect to clustering variable(s), rather than subjectively predetermined threshold values adopted by major international organizations, like UNDP, to make their classification. By investigating the multi-dimensional clustering results, this paper describes the features of each of the four tiers based on their characteristics within the three developmental aspects, explores the patterns of cross-tier disparities, and tracks the evolutions from a historical perspective. Also found is that, in China, the overall regional disparities have been increasingly attributable to regional economic disparities.     

A hierarchical point process with application to storm cell modelling

In environmetrics, interest often centres around the development of models and methods for making inference on observed point patterns assumed to be generated by latent spatial or spatio‐temporal processes, which may have a hierarchical structure. In this research, motivated by the analysis of spatio‐temporal storm cell data, we generalize the Neyman–Scott parent–child process to account for hierarchical clustering. This is accomplished by allowing the parents to follow a log‐Gaussian Cox process thereby incorporating correlation and facilitating inference at all levels of the hierarchy. This approach is applied to monthly storm cell data from the Bismarck, North Dakota radar station from April through August 2003 and we compare these results to simpler cluster processes to demonstrate the advantages of accounting for both levels of correlation present in these hierarchically clustered point patterns.

Cluster life cycle and diaspora effects: Evidence from the Indian IT cluster in Bangalore

The role of local clusters has been of interest to scholars and policymakers in international business alike. Research found that clusters enable a region to develop faster compared to dispersed economic activity, based mainly on a local concentration of competing and cooperating firms and sophisticated domestic demand. Locating in a cluster has certain benefits for firms stemming from pooling of human capital and supporting institutions varying by industry and international specialization.In this paper, we extend the local view of clusters and emphasize the complementary role of non-local linkages, in particular diasporas, illustrating our model employing the case of the evolution of the Bangalore IT cluster. The novelty of our paper lies in its longitudinal character. We are thereby able to identify how the roles of local and non-local networks differ across life-cycle phases; moreover, we find that diasporas can trigger or accelerate local development. We discuss implications for managers and policy makers.
