信息平台:三网融合的产业制高点

三网融合最直观的影响是消融了传媒产业、信息技术产业和电子通信产业的边界,形成了一个"媒信通融合大产业",而三网融合最深远的影响则是竞争方式的改变和竞争焦点的转移。以开放、对等、协作、共享为特征的"平台模式"将成为融合产业中最具竞争力的发展模式,而"信息平台"这种新型产业组织形式将成为三网融合产业竞争中的制高点。     

The e-government research domain: A triple helix network analysis of collaboration at the regional,country, and institutional levels

This study introduces a hybrid approach (i.e., a social network analysis technique and triple helix indicators) to study certain aspects of the e-government (EG) domain that would otherwise remain hidden when using conventional analytic tools. Particularly, we provide network analysis of the EG research domain by focusing on the network collaboration between regions, nations and institutions. We collected and analyzed 1091 scholarly papers which were classified as being about “e-government” by the Web of Science database. The results indicate that hybrid method can be used to understand certain network-level structures and patterns in the EG domain which are beyond the scope of the predominantly-used systematic literature review (SLR) method. Particularly, the hybrid method is useful in understanding collaboration patterns between countries, institutions and regions in the EG domain, identifying key players by studying their network properties (i.e., degree centralities); and in understanding the pattern of relations among universities, industries, and government. The implications of these results in terms of research and practice, and study limitations are discussed.     

Efficiency,unused capacity and transmission power as indicators of the Triple Helix of university–industry–government relationships

In this paper, we show that an information source composed with n random variables may be split into 2ⁿ or 2ⁿ − 1 “states”; therefore, one could compute the maximum entropy of the source. We derive the efficiency and the unused capacity of an information source. We demonstrate that in more than two dimensions, the transmission's variability depends on the system configuration; thus, we determine the upper and the lower bounds to the mutual information and propose the transmission power as an indicator of the Triple Helix of university–industry–government relationships. The transmission power is defined as the fraction of the total ‘configurational information’ produced in a system; it appears like the efficiency of the transmission and may be interpreted as the strength of the variables dependency, the strength of the synergy between the system's variable or the strength of information flow within the system.     

关于商高数的Terai猜想

设{a,b,c}是一组b为偶数的本原商高数．证明了：当a是形如16（3k＋1）＋1的素数时,Terai猜想对于几乎所有这样的素数都成立,特别地,当a=17（b=144,c=145）时,Terai猜想成立;当a是形如16（8kl＋5（k＋l）＋3）＋1的素数时,Terai猜想成立．     

不同省域政产学研合作体系的耦合效应比较

采用三螺旋互信息算法,基于SCI-E数据库,对我国2013—2015年北京市、上海市、浙江省等23个省级行政区政产学研合作体系的结构性问题进行比较分析。结果发现,我国大多数省级行政区政产学研合作体系的耦合效应比较差,区域创新体系的整体优化程度、结构性条件不合理。
