潜伏-隔离机制下的信息扩散拓展模型及稳定性

为适应信息扩散中病毒传播的复杂性和不确定性,在传统病毒传播模型和信息扩散模型基础上,引入潜伏状态和隔离状态,研究潜伏-隔离机制下的信息扩散模型及其稳定性。构建基于潜伏-隔离机制的信息扩散模型;运用劳斯稳定性判据,论证系统平衡点的局部稳定性,分析基本再生数R0及其对网络感染源和系统状态的影响;通过仿真实验,分析节点连通半径、节点分布密度和节点接触率对信息扩散的影响。仿真结果表明:通过调整节点连通半径、节点分布密度和节点接触率等参数,可实现对信息扩散的有效控制。     

EU security sector reform in Bosnia and Herzegovina: Reform or resist?

ABSTRACT

Attempts to explain the failure to reform the security sectors in post-conflict countries have often resorted to two sets of explanatory factors: international and local factors. This article seeks to move from that unhelpful dichotomy to an explanation linking both factors. Drawing on a Foucauldian approach and the concept of “counter-conduct,” it examines the rationality and practices of European Union (EU) governmentality and how governing technologies are resisted and reversed by local elites involved in security sector reform (SSR). Instead of understanding power and resistance as binary opposites, this article argues that counter-conduct can be conceived as implicated in the very relations of power that it seeks to resist. To tease out these relations, the article analyzes the EU's efforts in SSR in Bosnia and Herzegovina, where it identifies four forms of counter-conduct: upholding European standards, using the local ownership trap, simulating reforms, and lowering the bar.     

基于区块链的地学大数据管理

随着地理观测技术、计算机网络和地理信息系统、社会调查统计的迅速发展,具有空间位置的自然环境数据正在急剧增长,上升到大数据级别。而传统的数据库已经无法满足现有地学大数据的规模和增长速度。在资源访问方面,人们更加担心数据安全与隐私保护问题。由于数据交易的双方和交易中介都是互不信任的,这显然不利于数据的共享与流通,将阻碍地学大数据产业的发展。常用地学数据管理系统主要由单一机构进行维护管理,在多方用户参与的情形下,由于无法信任数据库中的数据,每一方用户都需要一个专用数据库,这样不同数据库之间数据的差异将产生繁琐的争议。区块链的到来却给这一问题的解决带来了希望,区块链技术实现了不完全可信网络环境中的可信数据管理,具有去中心化、防篡改、不可抵赖、完整性等特性,从而为解决目前依靠中心或第三方机构存在的高成本低效率和信息安全问题提供了切实的方法。本文从区块链的共识机制、智能合约、身份验证、数据溯源等方面进行阐述,并重点分析区块链如何解决流通和共享数据的问题,让地学大数据真正得以广泛应用。     

Effective? Locally owned? Beyond the technocratic perspective on the European Union Police Mission for the Palestinian Territories

ABSTRACT

The European Union Police Mission for the Palestinian Territories (EUPOL COPPS) was established in 2006 to contribute to the establishment of effective policing in support of an independent and democratic Palestinian state. EUPOL COPPS is often commended for its contribution to the professionalization of the Palestinian security sector under local ownership. Drawing on 40 interviews, we argue that the mission can be considered effective and locally owned only from a narrow technocratic perspective, which denies the political reality of continued occupation and absence of democracy. A broader analysis, which includes the voices of ordinary Palestinians, reveals that EUPOL COPPS contributed to the professionalization of authoritarian policing under continued Israeli occupation. Our findings show the limits of technocratic approaches to peacebuilding interventions and call for a stronger engagement with the ultimate beneficiaries of peacebuilding missions.     

Herdsmen militancy and humanitarian crisis in Nigeria: A theoretical briefing

This article explores the phenomenon of herdsmen militancy as a new trajectory for the farmer–herder crisis in Nigeria, with reference to its humanitarian implications. Relying on a systematic analysis of secondary data and aligning with the analytical anchorage of liberal political ecology theory, the article posits that herdsmen militancy depicts a contradiction in agrarian relations in the context of a national security crisis which has been complicated by salient socio-ecological factors such as climate change, armed violence, and identity politics. In view of the dire humanitarian consequences of this situation, the article submits that herdsmen militancy constitutes a major threat to human and national security in Nigeria. It makes a case for a pragmatic policy capable of mitigating the myriad socio-ecological factors that tend to trigger herdsmen militancy, with prohibition on open grazing in critical hotbeds of herder–farmer conflict as a strategic measure.     

Regional responses to security and development challenges in East and Southern Africa: lessons and way forward

Since the mid-twentieth century, the East and Southern African regions have been mired in complex and overlapping security and development challenges, including ethnopolitical conflicts, terrorist insurgencies, the proliferation of small arms and light weapons (SALWs), and overwhelming economic crisis. These challenges have had implications for human security, socio-economic development, territorial authority, sovereignty and the stability and legitimacy of political regimes in the affected states. The adequacy and relevance of the regional responses to these challenges is the subject of ongoing debate, to which this paper now adds. Among other factors, this paper identifies competition for regional dominance and institutional inadequacies as accounting for the inability of regional governance bodies to respond adequately to the challenges they face. Consequently, it recommends the expansion of the mandate of the Regional Economic Communities (RECs) beyond regional economic integration to include peacebuilding and a deepening of the institutional efforts focused on security cooperation and conflict management.     

Turning the tides of war: The impact of private military and security companies on Nigeria’s counterinsurgency against Boko Haram

Since the 2003 war in Iraq, private military and security companies (PMSCs) have become increasingly legitimate actors in modern conflicts. Despite this normative shift, rumours in March 2015 regarding the use of South African mercenaries in Nigeria to combat Boko Haram insurgents caused an international outrage, while the Nigerian government remained nonchalantly silent on the matter. This article investigates the impact of mercenaries on the conflict in the last six months of the Jonathan government. Using primary and secondary qualitative research, it assesses the role that PMSCs played in Nigeria’s counterinsurgency strategy, along with the ensuing reaction of international and local media to the outsourcing of violence to foreign companies. The article concludes that – notwithstanding the improved image of PMSCs in the world, and the actual impact of the contractors on the Nigerian counterinsurgency effort – the stigma of mercenaries continues to plague the industry, particularly on the African continent.
