COSMIC: Complexity in Spatial Dynamics

COSMIC（复杂性空间动力学）是三个研究小组（阿姆斯特丹自由大学（VU）、伦敦大学学院和梅努斯爱尔兰国立大学（NUIM））之间的一个提案，涉及城市科学和地理空间分析。该网络将重点关注城市动态过程，使用为整个人口收集的新的自下而上的数字数据。我们相信这些数据将为城市变化提供戏剧性的新见解，这些变化通常以不连续的形式表现出来，可以用各种反应-扩散动力学来表达，包括灾难、混乱、分岔和相变。在城市中，这种反应从边缘城市的出现到居住隔离的模式，体现了各种形式的社会排斥。我们首先开发了一个城市动态过程的类型学，以指导使用从电子交易（如电话线、电子票务和相关的地理传感）实时收集的新数字数据的模型的开发。我们的统一重点将是与底层网络相关的流量数据，以及围绕从劳动力市场到行人运动的空间相互作用的模型。VU将探索估计德国劳动力市场和阿姆斯特丹城市导航动态模型的方法，UCL将从伦敦的电话和票务数据中开发移动和位置模型，而NUIM将探索以都柏林的建筑和街景规模为代表的小规模环境中的移动。该网络将得到三个主要讲习班、各地点之间研究人员的交流以及与其他团体的强有力的外部联系的支持，预期从这个试点项目中将产生一个更广泛的网络的建议。

COSMIC (COmplexity in Spatial dynaMICs) is a proposal linking three research groups (Vrie University (VU) Amsterdam, UCL and National University of Ireland at Maynooth (NUIM)) dealing with urban science and geo-spatial analysis. The network will focus on urban dynamic processes using new bottom up, digital data collected for entire populations. We believe that such data will provide dramatically new insights into urban change which manifest themselves in often discontinuous forms which can be articulated using a variety of reaction-diffusion dynamics incorporating catastrophe, chaos, bifurcations, and phase transitions. In cities, such reactions range from the emergence of edge cities to patterns of residential segregation, embodying social exclusion in various forms. We first develop a typology of urban dynamic processes to guide the development of models using new digital data collected in real time from electronic transactions such as phone lines, electronic ticketing, and related geo-sensing. Our unifying focus will be on flow data associated with underlying networks with the models revolving around spatial interaction from labour markets to pedestrian movement. VU will explore methods for estimating dynamic models of labour markets in Germany and urban navigation in Amsterdam, UCL will develop models of movement and location from phone and ticketing data in London, while NUIM will explore movement in small scale environments represented at the building and streetscape scale in Dublin. The network will be supported by three major workshops, exchanges of researchers between sites, and strong external links to other groups, in anticipation that from this pilot project, a proposal for a much wider network will emerge.
