Abstract Building on world-systems theory, simulation models of 5-line intersocietal networks were generated in an effort to understand systemic power hierarchies. The societal nodes were exclusively connected by three types of interaction: migration, warfare, and unequal trade. These networks can be considered “mixed relation” networks due to the ways in which these types of ties combine positive and negative sanction flows. Insights from elementary theory were employed to understand how exclusion from these different types of ties might influence the resulting power distributions. Additionally, the resource carrying capacity of the nodes was varied by structural position in an effort to differentiate the influence of structural position and individual attributes on location in the hierarchy. It was determined that exclusion from interaction is likely a structural, scale invariant mechanism that helps to determine power distributions above and beyond the inherent attributes of network actors.
摘要基于世界系统理论,建立了五线社会间网络的仿真模型,试图理解系统的权力等级。社会节点只通过三种类型的互动联系在一起:移民、战争和不平等贸易。这些网络可以被认为是“混合关系”网络,因为这些类型的联系结合了积极和消极制裁流的方式。从基本理论的见解被用来理解如何排除这些不同类型的关系可能会影响最终的权力分配。此外,节点的资源承载能力随结构位置的变化而变化,以区分结构位置和个体属性对层次中位置的影响。研究确定,排除在互动之外可能是一种结构性的、规模不变的机制,有助于确定超越网络行为者固有属性的权力分配。

Abstract Advances in text analysis, particularly the ability to extract network based information from texts, is enabling researches to conduct detailed socio-cultural ethnographies rapidly by retrieving characteristic descriptions from texts and fusing the results from varied sources. We describe this process and illustrate it in the context of conflict in the Sudan. We show how network information can be extracted from vast quantities of unstructured texts-based information using computer assisted processes. This is illustrated by an examination of changes in the political networks in Sudan as extracted from the Sudan Tribune. We find that this approach enables rapid high level assessment of a socio-cultural environment, generates results that are viewed as accurate by subject matter experts, and match actual historical events. The relative value of this socio-cultural analysis approach is discussed.
文本分析的进步,特别是从文本中提取基于网络的信息的能力,使研究人员能够通过从文本中检索特征描述并融合来自不同来源的结果来快速进行详细的社会文化人种志研究。我们将描述这一进程,并在苏丹冲突的背景下加以说明。我们展示了如何使用计算机辅助处理从大量非结构化的基于文本的信息中提取网络信息。摘自《苏丹论坛报》的对苏丹政治网络变化的审查说明了这一点。我们发现这种方法能够对社会文化环境进行快速的高水平评估,产生的结果被主题专家认为是准确的,并且与实际的历史事件相匹配。讨论了这种社会文化分析方法的相对价值。

Abstract In this paper, we employ archival materials from multiple institutional sources to reconstruct the dynamic network of interorganizational collaboration that emerged in response to the Hurricane Katrina disaster of late 2005. Over the period from initial storm formation through the first week following landfall in Louisiana, we record active participation by over 1,500 organizations in response activities. We here conduct an exploratory analysis of the growth and evolution of the network of collaboration among responding organizations, an identification of organizations that emerged as central actors in the response process, and the cohesive subgroups that crystallized within the larger network. Finally, we conclude with a discussion of several issues related to the use of archival methods in research on interorganizational networks in disaster settings, and to the use of automated methods for network extraction.

Choosing the ‘β’ Parameter When Using the Bonacich Power Measure 在使用波纳契功率测量时选择“β”参数
Q2 Social Sciences Pub Date : 2011-01-01 DOI: 10.21307/JOSS-2019-032
Simon Rodan
Abstract Bonacich (1987) suggested a family of centrality measures that provide a useful way of modeling questions of power and network constraint. However, the literature offers little guidance regarding the choice of β, the parameter which alters the way the measure accounts for the effect of having powerful contacts in ones network. In this paper I explore the way the choice of the β parameter affects the power indices the Bonacich measure generates. I consider three network properties which might affect the way the choice of β influences the Bonacich power indices. I find that in high density networks with few internal ‘chains’ and few pendants, the choice of β is largely immaterial. Conversely, in sparse networks, those with a high proportion of pendant nodes, or those with many chains, the value of β has a substantial effect on the power indices the measure generates. Next I consider whether power indices produced by interior values of β might be represented as a linear combination of “pure” vectors, those generated with values of β at either end of the parameter range and β = 0. I find that in the vast majority of cases a linear combination of “pure” vectors power is equivalent to using indices produced by interior values of β, making the choice of β largely moot. Finally, in the unlikely case that this disaggregation is inappropriate, I discuss the question of determining an appropriate value of β empirically.
Bonacich(1987)提出了一系列中心性度量,为权力和网络约束问题的建模提供了一种有用的方法。然而,文献对β的选择提供了很少的指导,β是一个参数,它改变了衡量在一个网络中拥有强大联系的影响的方式。本文探讨了β参数的选择对波那契测度产生的功率指标的影响。我考虑了三种可能影响β的选择影响波纳契幂指数的网络性质。我发现,在高密度的网络中,内部“链”和垂坠很少,β的选择在很大程度上是无关紧要的。相反,在稀疏网络中,那些具有高比例的垂节点或具有许多链的网络中,β的值对度量产生的功率指标有实质性影响。接下来,我考虑由β的内部值产生的功率指数是否可以表示为“纯”向量的线性组合,这些向量在参数范围的两端和β = 0产生的β值。我发现,在绝大多数情况下,“纯”向量幂的线性组合相当于使用由β的内部值产生的指标,这使得β的选择在很大程度上没有意义。最后,在这种不太可能的情况下,这种分解是不合适的,我讨论了确定一个适当的β值的问题。

Abstract In the present study, the social linkages of street-involved youth and correlates of infection with chlamydia and gonorrhea are explored. This is the first study to assess the social linkages of street- involved youth using RDS. Eleven street-involved youth aged 14 to 24 were selected as seeds to recruit their peers into the study using RDS (N=169). Study staff administered a questionnaire, obtained a urine specimen, and provided recruitment coupons to participants. A week later, participants were provided with test results and treatment if necessary. RDS Analysis Tool was used to assess the effectiveness of RDS and define the social linkages. A Fisher’s Exact test was used to identify any correlates of infection. Gender was the only variable that correlated with infection status (22 percent of females vs. 8 percent of males). A high proportion of male participants had never been tested before. Despite the fact that most female participants had been tested before, high infection rates indicate that more accessible and frequent testing is required. Street-involved youth are connected socially to those who share similar health related behaviors. There is a need for increased testing options and opportunities for street-involved youth.
摘要在本研究中,街头参与青年的社会联系和衣原体和淋病感染的相关因素进行了探讨。这是第一个使用RDS评估街头青少年社会联系的研究。11名年龄在14至24岁之间的街头青少年被选为种子,使用RDS方法招募他们的同龄人加入研究(N=169)。研究人员发放了一份调查问卷,获取了尿液样本,并向参与者提供了招募券。一周后,向参与者提供测试结果和必要的治疗。使用RDS分析工具评估RDS的有效性并定义社会联系。费雪氏精确试验用于确定感染的相关因素。性别是与感染状况相关的唯一变量(22%的女性对8%的男性)。很大一部分男性参与者以前从未接受过测试。尽管大多数女性参与者以前都接受过检测,但高感染率表明需要更容易获得和更频繁的检测。街头青年在社会上与那些有类似健康相关行为的人有联系。有必要为街头青年提供更多的测试选择和机会。

Strategies for Combating Dark Networks 打击暗网络的策略
Q2 Social Sciences Pub Date : 2011-01-01 DOI: 10.21307/JOSS-2019-030
N. Roberts, Sean F. Everton
Abstract Our goal in this paper is to explore two generic approaches to disrupting dark networks: kinetic and non-kinetic. The kinetic approach involves aggressive and offensive measures to eliminate or capture network members and their supporters, while the non-kinetic approach involves the use of subtle, non-coercive means for combating dark networks. Two strategies derive from the kinetic approach: Targeting and Capacity-building. Four strategies derive from the non-kinetic approach: Institution-Building, Psychological Operations, Information Operations and Rehabilitation. We use network data from Noordin Top’s South East Asian terror network to illustrate how both kinetic and non-kinetic strategies could be pursued depending on a commander’s intent. Using this strategic framework as a backdrop, we strongly advise the use of SNA metrics in developing alterative counter-terrorism strategies that are contextdependent rather than letting SNA metrics define and drive a particular strategy.
我们在本文中的目标是探索两种破坏暗网络的通用方法:动力学和非动力学。动态方法涉及积极和进攻性的措施,以消除或捕获网络成员及其支持者,而非动态方法涉及使用微妙的,非强制性的手段来打击黑暗网络。两种策略源于动态方法:目标和能力建设。非动态方法产生了四项战略:体制建设、心理行动、信息行动和康复。我们使用Noordin Top东南亚恐怖网络的网络数据来说明如何根据指挥官的意图采取动态和非动态战略。以这一战略框架为背景,我们强烈建议在制定依赖于具体情况的替代反恐战略时使用国民核算体系指标,而不是让国民核算体系指标定义和推动特定战略。

Bonacich (1987) suggested a family of centrality measures that provide a useful way of modeling questions of power and network constraint.

Parallel Arc Diagrams: Visualizing Temporal Interactions 平行弧线图:可视化时间交互
Q2 Social Sciences Pub Date : 2011-01-01 DOI: 10.21307/JOSS-2019-036
P. Hoek
Abstract This paper introduces a new computer-based visualization method, the parallel arc diagram (PAD), which is capable of uniquely representing 2-mode temporal relationships in a manner that assists in highlighting simple features of the network. The PAD approach relies on a computer’s ability to render link lines adjacent to each other with orderly precision, resulting in features that facilitate preattentive processing of simple network characteristics and providing the ability to discern patterns of interactions over time. PADs supplement existing methods such as node-link diagrams by offering a simple alternative visualization without the computational complexity of graph layout algorithms and the additional issues that animation introduces. This paper subjectively evaluates the PAD approach using low level task taxonomies developed for assessing adjacency matrix and node-link visualization effectiveness. We argue based on those taxonomies that the PAD approach is as effective or in some cases more effective than existing approaches except for tasks requiring the identification of structural groups or middle-man nodes. This paper also demonstrates how the PAD approach can be utilized in a software application. The TIPAD (Temporal Interactive Parallel Arc Diagram) uses character participation in movie scenes as a test-bed for exploring social interactions over time and provides the ability to compare a PAD based visualization with traditional visualizations of the same network.
本文介绍了一种新的基于计算机的可视化方法——平行弧线图(PAD),它能够以一种有助于突出网络简单特征的方式唯一地表示两模时间关系。PAD方法依赖于计算机以有序的精度呈现彼此相邻的连接线的能力,从而产生有助于对简单网络特征进行预先注意处理的功能,并提供识别随时间变化的交互模式的能力。pad通过提供一种简单的替代可视化来补充现有的方法,例如节点链接图,而没有图形布局算法的计算复杂性和动画引入的附加问题。本文使用低级任务分类法对PAD方法进行主观评价,这些分类法用于评估邻接矩阵和节点链接的可视化效果。基于这些分类,我们认为除了需要识别结构组或中间人节点的任务外,PAD方法与现有方法一样有效,甚至在某些情况下比现有方法更有效。本文还演示了如何在软件应用程序中使用PAD方法。TIPAD(时间交互平行弧线图)使用电影场景中的角色参与作为测试平台,用于探索随时间推移的社会互动,并提供将基于PAD的可视化与同一网络的传统可视化进行比较的能力。

Abstract Labor mobility, both as a mechanism of knowledge diffusion and as a kind of social glue that holds together small production communities operative within a given territory, deserves serious consideration. In this context, focusing on a specific industrial cluster in Ankara, this paper reveals the extent and characteristics of the social networks created by the mobile laborers in order to understand the interconnections between social context, knowledge spillovers, innovation and labor mobility. For this purpose a step-wise algorithm is employed in order to identify social sub-groups by employing social network analysis and by drawing on the flow data constructed for this study. What is evident from this study is that the social network created by the mobility of laborers in Siteler, an industrial cluster specialized in furniture production, reveals a topography of social relations that cannot be split into equally large blocks but eventually parceled out to micro parts consisting of generally 2 or 3 firms. Interestingly, the contexts of innovation also unveil that innovative firms tend to be located at an intermediate position, not an upper and central position, within the topography of the network.
劳动力流动既是知识传播的机制,也是一种将特定区域内的小型生产社区凝聚在一起的社会粘合剂,值得认真考虑。在此背景下,本文以安卡拉的一个特定产业集群为研究对象,揭示了流动劳动者创造的社会网络的范围和特征,以了解社会语境、知识溢出、创新与劳动力流动之间的相互联系。为此目的,采用逐步算法,通过使用社会网络分析和利用为本研究构建的流量数据来识别社会子群体。从这项研究中可以明显看出,在专门从事家具生产的产业集群Siteler中,由劳动力流动创造的社会网络揭示了一种社会关系的地形,这种社会关系不能被分割成同样大的块,而是最终被分割成通常由2或3家公司组成的微观部分。有趣的是,创新的背景也揭示了创新企业往往位于网络地形中的中间位置,而不是上层和中心位置。

Abstract We propose a visual representation of bibliographic data based on shared references. Our method employs a distance metric that is derived from bibliographic coupling and then subjected to fast approximate multidimensional scaling. Its utility is demonstrated by an explorative analysis of social network publications that, most notably, depicts the genesis of an area now commonly referred to as network science. However, the example also illustrates some common pitfalls in bibliometric analysis.
摘要提出了一种基于共享参考文献的书目数据可视化表示方法。我们的方法采用从书目耦合中导出的距离度量,然后进行快速近似多维标度。对社会网络出版物的探索性分析证明了它的效用,最值得注意的是,它描述了一个现在通常被称为网络科学的领域的起源。然而,这个例子也说明了文献计量学分析中的一些常见缺陷。
