以上海交通大学的Academic Ranking of World University(ARWU)人文社会科学领域排名前50位的研究机构为研究对象,以Web of Science为统计数据来源,应用统计学原理和方法分析h-index与ARWU排名中的各项评价指标以及与传统的文献计量指标之间的关联性,结果表明:h-index与ARWU的核心指标、与论文发表总数和被引频次都有着很强的关联性,总被引频次和单篇引用频次分别符合hirsch模型和Glanzel-Shubert模型,并实际计算出两个模型中的参数α和c。总之,为h-index在人文社会科学领域的适用性研究提供进一步的实证。

有向加权网络是复杂网络中较为复杂的且贴合实际的一类,基于此,本文研究有向加权网络中的节点重要性排序,主要关注h-index类指标。文章从以下几个方面开展:第一,由于边的方向性和权值,我们将h-index类指标推广到有向加权网络中,重新定义了有向加权网络中节点的一般度、各阶h-index和coreness,并且给出一般性的方法框架,该框架不仅将网络“入”的信息和“出”的信息整合看待,还涵盖了不同的度的定义方法。另外,理论分析显示这三者之间具有内在联系,关系表明节点的一般度可作为初始状态,节点的各阶h-index可作为中间过渡态,节点的coreness可作为稳态。同时,我们设计了前述方法的计算算法,并给出示例以及在真实网络中应用,结果表明一阶h-index(h指数)能更好的刻画网络中“枢纽”节点的重要性。第二,基于网络节点强度而不是节点度构建有向加权无标度网络,并给出网络生成算法。该算法在保持增长特性和优先连接机制下,引入权重自适应演化机制。理论和数值分析均表明由该算法生成的有向加权无标度网络符合幂律特征,且幂律指数与网络尺寸无关,但与模型的初始参数有关。第三,在理想的有向加权无标度网络模型的基础上,为探究某一类真实网络的统计特征,构建基于真实网络信息的无标度网络模型。进一步地,我们将hindex的一般性方法框架应用到该网络模型中,计算网络中的节点重要性排序。

本文提出了一个统一的框架将k-core方法和h-index指标推广到带权网络和多层网络。首先,从理论的角度,给出了定义带权网络节点的一般度、各阶h-index和coreness的一般方法,并证明了在一般条件下三者之间联系:节点的零阶h-index与节点的一般度相等,节点的无穷阶h-index与节点的coreness相等。从定义出发,我们展示了如何将已有的关于带权网络的k-core方法纳入我们的框架之中,并进一步设计了两种新的k-core方法。从数量关系出发,我们展示了如何设计计算节点的coreness的并行算法和分布式算法。在数值实验部分,本文通过四个实际网络,比较了四种带权网络的k-core方法在节点传播影响力排序中的效果。数值结果显示,无论针对哪种k-core方法,1阶的h-index指标总是表现最优或者次优。最后,我们将该框架进一步推广到多层网络,证明了在多层网络下,同样可以定义节点的一般度、各阶h-index和coreness,并使之保持与单层网络类似的关系。如何在多层网络的不同层层关系下定义不同的节点coreness和各阶h-index也在最后做了简单讨论。

SCI首要的功能是引文功能,可帮助科技人员获取需要的最新文献、跟踪国际学术前沿、及时了解国际学术动态、构思重大科学问题等提供信息;其次是在引文索引实践中衍生出对科技研究成果评估的功能,主要侧重于SCI论文数量和期刊影响因子。ESI则是在SCI和SSCI基础上,针对22个专业领域,分别对国家、研究机构、期刊、论文以及科学家10年的数据进行统计分析和排序,主要指标包括:论文收录数、论文被引频次、论文篇均被引频次等;ESI的闪光点是对于论文质量的评价。h-index则是指一个人有N篇论文分别被引用了至少N次;它不仅可以用于评估研究人员过去的学术水平,也可以用于预测未来的学术成就。在科研评估实践中,仅以SCI论文数量为考核指标易致短期行为,而ESI和h-index则是一种长效机制。

Peer-to-Peer Desktop Grid （P2PDG） has emerged as a pervasive cyber-infrastructure tackling many largescale applications with high impacts. As a burgeoning research area, P2PDG can support numerous applications, including scientific computing, file sharing, web services, and virtual organization for collaborative activities and projects. To handle trustworthiness issues of these services, trust and reputation schemes are proposed to establish trust among peers in P2PDG. In this paper, we propose a robust group trust management system, called h-Trust, inspired by the h-index aggregation technique. Leveraging the robustness of the h-index algorithm under incomplete and uncertain circumstances, h-Trust offers a robust personalized reputation evaluation mechanism for both individual and group trusts with minimal communication and computation overheads. We present the h-Trust scheme in five phases, including trust recording, local trust evaluation, trust query phase, spatial-temporal update phase, and group reputation evaluation phases. The rationale for its design, the analysis of the algorithm are further investigated. To validate the performance of h-Trust scheme, we designed the h-Trust simulator hTrust-Sim to conduct multi-agent-based simulations. Simulation results demonstrate that h-Trust is robust and can identify and isolate malicious peers in large scale systems even when a large portion of peers are malicious.

There are two types of cell death-apoptosis and necrosis. Apoptosis is cell death regulated by cell signaling pathways, while necrosis has until recently been considered a passive mechanism of cell death caused by environmental pressures. however, recent studies show that necrosis can also be regulated by specific cell signaling pathways. This mode of death, termed necroptosis, has been found to be related to the occurrence and development of many diseases. We used bibliometrics to analyze the global output of literature on necroptosis in the field of neuroscience published in the period 2007–2019 to identify research hotspots and prospects. We included 145 necroptosisrelated publications and 2239 references published in the Web of Science during 2007–2019. Visualization analysis revealed that the number of publications related to necroptosis has increased year by year, reaching a peak in 2019. China is the country with the largest number of publications. Key word and literature analyses demonstrated that mitochondrial function change, stroke, ischemia/reperfusion and neuroinflammation are likely the research hotspots and future directions of necroptosis research in the nervous system. The relationship between immune response-related factors, damage-associated molecular patterns, pathogen-associated molecular patterns and necroptosis may become a potential research hotspot in the future. Taken together, our findings suggest that although the inherent limitations of bibliometrics may affect the accuracy of the literature-based prediction of research hotspots, the results obtained from the included publications can provide a reference for the study of necroptosis in the field of neuroscience.
