网络视域下党反腐倡廉建设的现状与路径选择

信息时代下,网络反腐在党的反腐倡廉建设中具有参与主体广、信息传递快、舆论监督压力大等优势,对党的反腐倡廉建设有重要的作用。随着人民群众反腐期望值的持续上升,新时期党的网络反腐工作也遭遇了许多困境：网络监督的自发性和偶然性缺乏完善的执法制度规范;网络的隐蔽性和匿名性容易导致网络暴力,伤及无辜;网民的非理性参与行动容易破坏社会的安定团结。深入推进新时期反腐倡廉建设,一方面需要积极应对,充分利用网络新兴技术形成新的监督体系,另一方面需要正确认识网络反腐的局限性,加强制度创新,实现网络反腐与制度反腐有效对接。     

我国斜向府际关系初探

政府间关系步入网络化时代,斜向府际关系应运而生。斜向府际关系以中央部委及其垂直管理部门、中央直属机构和各级地方政府间关系为例,分析级别不同的跨部门行政机关之间、不同行政区域的地方政府之间关系。斜向府际关系旨在超越层级,营造动态网络交流环境,探析纵横交错、彼此渗透的多元地方政府和政府部门间关系;促进多元行政主体的良性互动,为多维节点的网络型府际关系探究做铺垫,实现后现代语境的多中心共治。

Determining the optimal double-component assignment for a stochastic computer network

This study determines the optimal double-component assignment based on the system reliability criterion for a computer system, in which the computer system is represented as a network with a set of links and a set of vertices. The double-component assignment is to assign a set of transmission lines (resp. facilities) to the links (resp. vertices) of the network, in which each transmission line (resp. facility) has multiple states due to maintenance or failure. Thus, the computer system according to any double-component assignment is called a stochastic computer network. The system reliability is the probability that the specific units of data are successfully transmitted through the stochastic computer network. An optimization algorithm which integrates the genetic algorithm, minimal paths, and Recursive Sum of Disjoint Products is utilized to find the optimal double-component assignment with maximal system reliability. Several computer networks are utilized to demonstrate the efficiency of the proposed algorithm compared with other algorithms. By solving this problem, data can be more reliably transmitted and thus the organization operation is executed more smoothly.

The Network Origins of Aggregate Fluctuations

This paper argues that, in the presence of intersectoral input–output linkages, microeconomic idiosyncratic shocks may lead to aggregate fluctuations. We show that, as the economy becomes more disaggregated, the rate at which aggregate volatility decays is determined by the structure of the network capturing such linkages. Our main results provide a characterization of this relationship in terms of the importance of different sectors as suppliers to their immediate customers, as well as their role as indirect suppliers to chains of downstream sectors. Such higher‐order interconnections capture the possibility of “cascade effects” whereby productivity shocks to a sector propagate not only to its immediate downstream customers, but also to the rest of the economy. Our results highlight that sizable aggregate volatility is obtained from sectoral idiosyncratic shocks only if there exists significant asymmetry in the roles that sectors play as suppliers to others, and that the “sparseness” of the input–output matrix is unrelated to the nature of aggregate fluctuations.
