政府信誉与自然垄断产业的规制绩效

政府信誉度高是政府对自然垄断产业的微观规制取得较好效果的必要条件，如果政府信誉度低，就会出现规制的失效。体制转轨中的中国，政府信誉低，这在政府规制中表现为：规制的法制环境存在根本性缺陷、政府规制背后的实质是行政垄断、规制部门身份与职能的重叠，等等。这一特性造成政府对自然垄断产业的规制绩效的低下，其相关的规制政策实际上造成市场扭曲和社会福利的损失。我们必须加强政府的法律制约并改善政府质量，才能提高政府信誉和规制绩效。     

The benefits brought by space—General public versus space agencies perspectives

Space agencies and governments have been long striving to find justification for the budgets allocated to non-commercial space missions. The most frequent justifications were scientific discoveries, technological development as well as national prestige. The current study aims to have a different look at the question “Which are the benefits brought by space?” by investigating/sampling/interrogating the public opinion and identifying the perception and view of the generation that form the bulk of the taxpaying citizens for the immediate future and will be actively financing any future missions. The study focuses on the answers provided to an online survey by an international sample of population. The target individuals are in the age range of 25–44 and are users of social networks. They are either employed or students, but they are not directly involved with the space sector. The survey aims to establish whether the promotional activities of ESA, NASA and other space agencies are aligned with the perceived benefits of this sample population. Is space contributing to what the target people consider important? What could be done to improve/change this perception? How did the public perception evolve? Which are the biggest problems humanity is confronted with today according to the sample population? Could space help addressing these major problems? The paper will firstly present the statistical analysis of the sample answers and the conclusions that can be drawn from them. In a second step it will compare the perceptions and expectations of the public in regards to space with the current space agencies strategies and identify the gaps and discontinuities.

化解乡村债务的基本思路及实现途径

乡村债务包括存量债务和增量债务两个部分，解决乡村债务问题就要从这两个方面入手。对于存量债务，可以通过债务重组的方式进行化解；对于增量债务文章提出了在新农村建设中，不仅不应一味地避免乡村新增债务，而且应该积极地采取有效措施，使乡村新增债务尤其是良性债务维持在适度的规模和水平之上的观点。

Strategies and determinants for successful space technology transfer

The following paper reports the results of a research work carried from 2008 on the topic of strategies and determinants of space technology Transfer (TT). In particular, the aim of this study is to present: 1. The policies and strategies the major space agencies adopt for TT, 2. The operational mechanisms and determinants involved in the transfer of space technologies to other industrial sectors. To this extent we have conducted in the last five years: six case studies of large space agencies, four TT case studies concerning the construction of scientific satellites, two case studies focused on space to earth TT programs undertaken by the Japanese aerospace agency, and two TT case studies examining Italian space companies.The comparative and comprehensive analyses of these studies indicate that the space agencies of the more industrialized countries aim primarily at consolidating and developing the industrial systems in their own countries, which include the use of technology transfer programs, and that the transfer of space technologies follows the route “Earth–Space–Earth”. With regard to the determinants of the TT process, the most important of these correlate with the type of technology in transfer, whereas organizational, economic and financial determinants have less significance.     

星间网络安全路由选择算法研究

星间网络由于拓扑结构高动态变化、可靠性安全性要求高、节点处理能力有限等特点,使其有别于普通的地面互联网。文章通过分析星间网络特性,对其中安全路由选择的关键技术进行深入研究,提出了一种基于节点信誉度评价与负载感知机制的星间网络安全路由选择算法。该算法采用混合路由配置策略,根据网络实时情况对路由进行动态调整,加入节点信誉度评价策略,减小恶意节点对网络的影响,并且增加节点负载感知机制,根据当前节点负载情况调整路由。最后,文章通过仿真实验验证算法性能,验证了算法在数据包传输成功率方面的优势。
