在阿克塞尔罗德的社会影响力模型的扩展的背景下，我们研究的文化漂移，表示为随机扰动，和大众媒体，通过引入外部均匀场之间的相互作用和竞争。与以前的研究不同[J。González-Avella {\it et al}，Phys.Rev.E {\bf 72}，065102（R）（2005）]，这里提出的大众媒体耦合能够影响社会中任何个体的文化特征，包括那些与外部信息不共享任何特征的人。一个噪声驱动的过渡被发现：对于大的噪声率，观察到的有序（文化极化）相和无序（文化碎片化）相，而较低的噪声率，有序相占上风。在前一种情况下，外部场被发现诱导文化秩序，一种行为相反，在以前的研究中使用不同的处方的大众媒体互动。我们比较了这个模型的预测，统计数据测量的影响，在巴西的大众媒体输精管结扎术推广活动。
英文摘要：
In the context of an extension of Axelrod's model for social influence, we study the interplay and competition between the cultural drift, represented as random perturbations, and mass media, introduced by means of an external homogeneous field. Unlike previous studies [J. C. González-Avella {\it et al}, Phys. Rev. E {\bf 72}, 065102(R) (2005)], the mass media coupling proposed here is capable of affecting the cultural traits of any individual in the society, including those who do not share any features with the external message. A noise-driven transition is found: for large noise rates, both the ordered (culturally polarized) phase and the disordered (culturally fragmented) phase are observed, while, for lower noise rates, the ordered phase prevails. In the former case, the external field is found to induce cultural ordering, a behavior opposite to that reported in previous studies using a different prescription for the mass media interaction. We compare the predictions of this model to statistical data measuring the impact of a mass media vasectomy promotion campaign in Brazil.
We investigate the collective behavior of a globalized society under the influence of endogenous mass media trends. The mass media trend is a global field corresponding to the statistical mode of the states of the agents in the system. The interaction dynamics is based on Axelrod's rules for the dissemination of culture. We find situations where the largest minority group, possessing a cultural state different from that of the predominant trend transmitted by the mass media, can grow to almost half of the size of the population. We show that this phenomenon occurs when a critical number of lon…

In real-time, social media data strongly imprints world events, popular culture, and day-to-day conversations by millions of ordinary people at a scale that is scarcely conventionalized and recorded. Vitally, and absent from many standard corpora such as books and news archives, sharing and commenting mechanisms are native to social media platforms, enabling us to quantify social amplification (i.e., popularity) of trending storylines and contemporary cultural phenomena. Here, we describe Storywrangler, a natural language processing instrument designed to carry out an ongoing, day-scale curati…
