Understanding the link between environmental pressures, sociality and health

2018财年，该项目在测试与信息传播和传染病相关的社会互动的成本和收益之间的权衡方面取得了进展。主要活动是：(I)考虑到上述成本和收益，继续调整我们的社会网络进化模型；(Ii)前往苏格兰启动一个涉及果蝇的项目的合作，然后运行设计的实验，以观察目标个人被人为感染细菌病原体时的社会互动；(Iii)继续编写一份手稿，记录社会网络如何在流行病的不同阶段影响疾病传播的动力学。果蝇的经验数据将是检验这类模型参数的关键。

In FY2018, this project progressed in testing the trade-off between the costs and benefits of social interactions as they relate to information transmission and infectious disease. The main activities were: (i) continued tweaking of our model of social network evolution in consideration of the above-mentioned costs and benefits; (ii) trips to Scotland to initiate collaboration on a project involving fruit flies and then running the designed experiments to observe social interactions when target individuals are artificially infected with bacterial pathogens; (iii) the continued work on a manuscript documenting dynamics in how social networks influence disease transmission at different stages of an epidemic. The empirical fruit fly data will be critical to test parameters of such models.
