摘要

社会网络的结构从根本上影响着传播动态。一般来说,个体之间的接触越多,信息或疾病传播的机会就越多。然而,个体之间的接触以及由此产生的任何传播事件都是由空间(个体选择在哪里移动)和社会规则(个体选择与谁互动或向谁学习)共同决定的。在这里,我们通过一个模拟模型来研究社会空间界面对传播动态的影响。我们量化了不同的移动规则(局部移动、半局部移动、游牧移动和基于资源的移动)和社会传播规则(简单传播、反一致性传播、比例传播、一致性传播和阈值规则)对社会网络结构和新行为传播的相对影响。本地化运动产生了弱连接的稀疏网络,游牧运动产生了弱连接的密集网络,而基于资源的运动则产生了强连接的模块化网络。不同的运动和传播规则组合所产生的传播速度各不相同,但重要的是,在静态和动态网络表征上进行模拟时,传播规则的相对排名也会发生变化。我们的研究结果表明,个体层面的社会和空间行为会影响新兴网络结构,并对复杂传播规则下的信息传播产生特殊影响。

The contribution of movement to social network structure and spreading dynamics under simple and complex transmission.

The structure of social networks fundamentally influences spreading dynamics. In general, the more contact between individuals, the more opportunity there is for the transmission of information or disease to take place. Yet, contact between individuals, and any resulting transmission events, are determined by a combination of spatial (where individuals choose to move) and social rules (who they choose to interact with or learn from). Here, we examine the effect of the social-spatial interface on spreading dynamics using a simulation model. We quantify the relative effects of different movement rules (localized, semi-localized, nomadic and resource-based movement) and social transmission rules (simple transmission, anti-conformity, proportional, conformity and threshold rules) to both the structure of social networks and spread of a novel behaviour. Localized movement created weakly connected sparse networks, nomadic movement created weakly connected dense networks, and resource-based movement generated strongly connected modular networks. The resulting rate of spreading varied with different combinations of movement and transmission rules, but-importantly-the relative rankings of transmission rules changed when running simulations on static versus dynamic representations of networks. Our results emphasize that individual-level social and spatial behaviours influence emergent network structure, and are of particular consequence for the spread of information under complex transmission rules.This article is part of the theme issue 'The spatial-social interface: a theoretical and empirical integration'.

期刊介绍: The journal publishes topics across the life sciences. As long as the core subject lies within the biological sciences, some issues may also include content crossing into other areas such as the physical sciences, social sciences, biophysics, policy, economics etc. Issues generally sit within four broad areas (although many issues sit across these areas): Organismal, environmental and evolutionary biology Neuroscience and cognition Cellular, molecular and developmental biology Health and disease.
