非矿安全生产技术支撑体系中心建立的研究

为了加强政府对安全生产的监督和监察,解决安全生产事故预防、事故鉴定分析、事故责任的确定、安全技术研究等问题,直接为各级安全监管部门履行职责,提供技术支撑和技术保障,需要建立安全生产技术支撑体系专业中心。该中心是提高政府监管监察能力的重要组成部分和具体举措。笔者依据国家安全生产技术支撑体系专业中心的框架,在综合分析非矿工业领域的安全生产事故特点的基础上,结合生产实际,提出了非矿工业安全生产技术支撑体系专业中心建立的具体方案,为各级政府部门建立体系专业中心,加强科学决策与监管提供了理论和实践依据。

中心统合主义:大一统国家的一个理论阐释

不同于帝国政治体系,大一统国家体现出中心统合主义的秩序机理。作为体系性范畴的中心,在治体论的传统构架上注重政治价值、主体与制度三类要素围绕系统和体系的双重统合。由此确立的体系中心是实现一体化秩序的动力机制,其实质是能够发展出统合性治理模式的核心力量。在此视野下,汉代从奉行黄老之学到尊儒更化的转变标志着体系统合的升级优化。这一类优化对于历史上政权的维续十分重要,其成败关系到国家巩固或衰败。中心统合主义机理不仅有助于把握大一统国家变迁的历史逻辑,也因其导向一体凝合的立国形态,从而与中心离散的帝国类型区分开来。

The determination of the link with the smallest end-to-end network latency in ethernet architecture

Ethernet fundamental and its data transmission model are introduced in brief and end-to-end network latency was analyzed in this paper. On the premise of not considering transmission quality and transmission cost, latency was the function of the rest of network resource parameter (NRP). The relation between the number of nodes and that of end-to-end links was presented. In ethernet architecture, the algorithm to determine the link with the smallest latency is a polynomial issue when the number of network nodes is limited, so it can be solved by way of polynomial equations. Latency measuring is the key issue to determine the link with the smallest network latency. 3-node brigade (regiment) level network centric warfare (NCW) demonstration platform was studied and the latency between the detectors and weapon control stations was taken as an example. The algorithm of end-to-end network latency and link information in NCW was presented. The algorithm program based on Server/Client architecture was developed. The data transmission optimal link is one whose end-to-end latency is the smallest. This paper solves the key issue to determine the link whose end-to-end latency is the smallest in ethernet architecture. The study can be widely applied to determine the optimal link which is in the complex network environment of multiple service provision points.

Peripheral Challenge in Container Port System:A Case Study of Pearl River Delta

The growth of peripheral ports to dominant hubs has been well documented in North America and Europe,and has led to the elaboration of several theoretical models.However,although changes in containerization growth have been taking place in the South and East Asia in recent years,particularly in China,only a few studies have fo-cused on this region.The Pearl(Zhujiang) River Delta(PRD) has a typical port system with hub and peripheral ports,and provides an excellent case for studying the Peripheral Challenge.This paper introduces the theoretical evidence of the Hayuth model and analyzes the evolution of the container port system in the PRD with five phases:1) phase I:preconditions for change and phase II:initial container port development in the 1970s and early 1980s;2) phase III:diffusion,consolidation,and port concentration in the middle and late 1980s;3) phase IV:the load center in the 1990s;and(4) phase V:the Peripheral Challenge since the late 1990s.The results illustrate that the Shenzhen port presents mounting challenges to the Hong Kong port,descending from a transshipment hub of China to a regional load center of Southeast China.Furthermore,this paper explores five points that have led to the evolution of the port system in the PRD:1) competition in the regional port systems;2) different interested parties;3) shift of investment strategies of in-ternational terminal operators;4) integration of shipping networks and reorganization of carriers;and 5) cost-based competition.

Service optimization in programmable cloud network

With the rapid development in cloud data centers and cloud service customers,the demand for high quality cloud service has been grown rapidly.To face this reality,this paper focuses on service optimization issues in cloud computing environment.First,a service-oriented architecture is proposed and programmable network facilities are utilized in it to optimize specific cloud services.Then various cloud services are categorized into two subcategories;static services and dynamic services.Furthermore,the concepts of cloud service quality and cloud resource idle rate are defined,and the aforementioned concepts have also been taken into consideration as parameters in the service optimization algorithm to improve the cloud service quality and optimize system workload simultaneously.Numerical simulations are conducted to verify the effectiveness of the proposed algorithm in balancing the workload of all servers.

The Analysis on social determinants of health of the floating population

Health literacy refers to the individual obtaining and understanding and dealing with the basic health information and/or services and the ability of use the information and services to make good health decisions.At present, research works related to health literacy in our country are in the initial stage, the information of floating population health literacy is blank, the Chinese Health Education Center （formerly the Chinese Disease Prevention and Control Center Health Education） Ministry of Social welfare studies undertaken special ＂Chinese public health Literacy survey and evaluation System ＂to develop a suitable evaluation index system of health literacy of the public, used for evaluation of our country＇ s public health literacy level. October to December 2007, the Chinese health education center of this set of evaluation index in Jinan Shandong province examines the health literacy status of floating population, analysis the influence factors of health literacy of the floating population, for the national macroeconomic regulation and control of the floating population, the rational allocation of health resources, determine priority health work, and provide evidence for health related policies and regulations of the floating population.
