社交媒体用户抗议支持者的可检测性和密度的空间变化
On spatial variation in the detectability and density of social media user protest supporters
摘要：
虽然已经发表了很多关于社交媒体上的街头抗议活动，很少有作品试图描述社交媒体用户在此类事件中的空间行为。这里报告的研究使用空间捕获-再捕获方法来确定建筑环境的影响，物理接近抗议地点，以及集体张贴节奏在墨西哥城抗议期间用户的空间可探测性和密度的变化。获得最好的模型，以及解释用户的空间密度，表明有很高的可变性，在社交媒体用户抗议支持者的可检测性和集体张贴节奏和观察的一天是显着的解释因素。这意味着，集体空间行为的研究将受益于集中在用户的活动中心和他们的城市环境，而不是他们的物理接近的抗议地点，后者无法充分解释空间变化的用户的可检测性和密度在抗议活动。
英文摘要：
Although much has been published regarding street protests on social media, few works have attempted to characterize social media users' spatial behavior in such events. The research reported here uses spatial capture-recapture methods to determine the influence of the built environment, physical proximity to protest location, and collective posting rhythm on variations in users' spatial detectability and density during a protest in Mexico City. The best-obtained model, together with explaining the spatial density of users, shows that there is high variability in the detectability of social media user protest supporters and that the collective posting rhythm and the day of observation are significant explanatory factors. The implication is that studies of collective spatial behavior would benefit by focussing on users' activity centres and their urban environment, rather than their physical proximity to the protest location, the latter being unable to adequately explain spatial variations in users' detectability and density during the protest event.
