一种复合的自治域级拓扑发现方法

随着网络技术的发展,面对新的挑战,传统网络逐渐力不从心,软件定义网络（software-defined network, SDN）领衔的未来网络应运而生,随之而来的是各类网络测量技术纷纷针对未来网络发生演变,但拓扑结构测量在传统网络环境下的作用仍然不可忽视。在自治域级的网络拓扑中,每个自治域都可以简化为一个点,而用两点之间的连线表示自治域间的邻接关系。近年来有许多相关的研究展示了不同的拓扑发现算法。提出了一种简单高效的方法来推断自治域级的拓扑,利用在网络中部署高速采集器采集边界网关协议（border gateway protocol,BGP）路由器上的路由表以及BGP协议的更新信息来推断网络拓扑结构,并判定自治域的相关属性。实验证明了该方法能够达到预期效果,全面、准确地推断网络在自治域级的拓扑结构。     

The resources of ageing? Middle‐aged gay men's accounts of Manchester's gay voluntary organizations

Middle‐aged men's experiences of gay voluntary organizations (GVOs) are neglected in research. To address this knowledge gap, this article extends Bourdieusian theorizing beyond that deployed by Hakim (2010) and Green (2008) concerning ‘erotic capital’ to demonstrate how norms in GVOs can facilitate or frustrate mobilization of ‘ageing capital’ by middle‐aged gay men living in Manchester (UK), which has implications for comparable cities within and beyond a UK context. Based on interviews with 22 men aged 39–55, this article demonstrates how ‘ageing capital’ can facilitate challenge to gay ageism but also how such ageism can frustrate and even overwhelm men's capacities to deploy ageing capital in generic GVOs, thus reinforcing intergenerational conflict and expression of ageism towards younger gay men. In doing so, this article contributes to knowledge about the reproduction of the relations of ageism in a particular field of gay existence.     

Many Faces of Security: Discursive Framing in Cross-border Natural Resource Governance in the Mekong River Commission

Abstract

In the past decade, security has emerged as a new discourse in water governance beyond transboundary conflicts and cooperation. This paper will examine how security is framed in the context of international river basin organizations (RBOs), key regional organizations in transboundary water governance operating in many international river basins around the world. As an example of cross-border governance, RBOs can promote joint cooperation and information sharing, and serve as a form to bring together diverse stakeholders. This paper focuses on the discursive construction of ‘security’ in a particular context of cross-border river basin governance in the Mekong River Basin. We ask: How is security framed in the discourse of RBOs? We examine how diverse actors frame security in the context of RBOs and at various scales and around certain management actions in a case study of the Mekong River Commission, a well-established RBO. Attention will be paid to the links between water security, food security, and energy security in the broader water and development discourse. We analyze what the findings mean for cross-border governance more broadly.     

Of River Linkage and Issue Linkage: Transboundary Conflict and Cooperation on the River Meuse

Abstract

It is a truism in mainstream International Relations that issue linkage promotes regime formation and integration. The present article applies this idea to the transboundary lower river Meuse and finds its history of integration to be a tortuous one. Contextual political factors have at times promoted integration, at times fragmentation. The path towards regional integration, then, has not been not linear, but has consisted of conflict and cooperation, of (Meuse–Scheldt) river linkage and issue linkage, but also counterlinkage and non-linkage. Clearly linkage is not necessarily positive. I will argue that this does not need to be problematic, but suggest accepting more complexity in the analysis of river integration. I propose a way to create some order in the many available concepts of linkage to map out the role of linkage in integration.     

We Did Not Realize about the Gender Issues. So,We Thought It Was a Good Idea

This article explores the link between nationalism, as expressed by the Burman state and ethnic and student opposition movements, and the emergence of a multiethnic women's movement engaged in resistance activities. In focusing on women's involvement in oppositional nation-making projects, this article aims to broaden our understanding of gender and conflict by highlighting women's agency in war. Drawing on interviews carried out with founding members of the women's movement, non-state armed groups and others active in civil society, the article investigates how a gendered political consciousness arose out of dissatisfaction with women's secondary position in armed opposition groups, leading to women forming a movement, not in opposition to conflict per se but in opposition to the rejection of their militarism, in the process redefining notions of political involvement and agency. By invoking solidarity based on a gendered positioning, rather than on an ethnic identity, the women's movement resisted the dominant nation-making projects, and created a nationalism inclusive of multiethnic differences. Burmese women's multiple wartime roles thus serve to upset supposed dichotomies between militancy and peace and victim and combatant, in the process redefining the relationship between gender, nationalism and militancy.     

水工美学的理论框架

人文水利要解决的是水与文化、水利与人的关系问题。水工美学的研究对象是山、水、水工建筑物的序结构,是美学四载体形、光、与声、色的最优配置。我们应以诗心、书骨、画眼、园趣、乐感、文蕴、哲理去建构水工美学。     

文明对话的发展及其世界意义

苏联解体 ,冷战结束 ,美国哈佛大学著名学者亨廷顿提出“文明冲突论”。他认为一场新的冷战为期不远 ,所不同的是已经过去的冷战是以意识形态为分野 ,而新的冷战是以文化为界线 ;过去的威胁是苏联 ,现在的威胁则是伊斯兰教—儒教的联盟。他的这个论点 ,国际大部分学者很难苟同。美国哈佛大学另一位著名学者杜维明教授则力主“文明对话论” ,他相信多元文化并存 ,通过对话和理解 ,通过各种文化自身的反省与变革 ,人类一定会迎来一个充满希望的新世纪。为此 ,几年来他在世界各地组织并参加一些“文明对话”的国际学术讨论会。在他的带动下 , 2 0 0 2年 8月哈佛大学—燕京学社与南京大学在南京召开了“文明对话国际学术讨论会” ,这是一次穆斯林学者与非穆斯林学者的文明对话的学术讨论会。本刊 2 0 0 2年第 4期已选载了这次会议的部分学术论文。在这次会议上杜维明先生发表了题为“文明对话的发展及其世界意义”的演讲 ,他视野开阔 ,观点新颖 ,在与会学者中引起很大的反响他认为很多杰出的学者已经看到亨廷顿“文明冲突论”非常狭隘的二分法破绽。如果要在全球化的过程中使各种不同的民族文化能够逐渐地在合而不同的背景下生存就需要通过对话,逐渐发展出生命共同 体的意愿 ;通过对话 ,大家都具有和平共     

少数民族地区水电移民安置的特殊性问题——来自四川少数民族移民的调查

西部水电资源的开发使少数民族移民问题日益突出,政策与实践的不匹配集中体现了现行政策框架未充分考虑少数民族的特殊性。目前水电移民研究多集中于移民安置补偿、扶持政策、利益分配等一般理论与实践层次,尚缺乏针对少数民族地区水电移民特殊性的深入研究。本文欲通过对少数民族地区水电移民安置特殊性问题的分析及探讨,旨在探求适应其发展的相应政策和途径,真正实现少数民族地区资源、人和社会的和谐发展,从而促进我国西部水电资源的可持续开发。     

追问盘古——盘古神话来源问题研究之一

盘古神话在先秦乃至秦汉时期的汉文古籍中均没有记载,直到三国时代才出现在徐整的《三五历纪》中。盘古神话源自何处?源自什么民族?这是近百年来学术界争论不休的一个问题。本文及以后将陆续发表的系列研究文章认为,盘古神话来源于华南珠江流域的两粤(广东、广西)地区,来源于华南珠江流域的原住民族——壮侗语民族。
