珀洛东超有机体与原合作行为

The peloton superorganism and protocooperative behavior

Hugh Trenchard

摘要:

提出了一个理论框架,在pelotons(团体的骑自行车者)的protocotive行为。在pelotons的合作和搭便车行为之间的阈值建模,一起构成protocooperative行为(不同于protocooperation)。原合作行为是一个功能:1。两个或两个以上的骑自行车者通过牵引益处耦合,2.骑自行车者的当前功率输出或速度,以及3.最大可持续产出(MSO)原型合作行为的特征包括:1。相对低速阶段,其中骑自行车的人自然地通过彼此并且共享最高成本的前部位置,以及2.骑自行车的人保持前面的人的速度,但不能超过的免费骑行阶段。原型合作行为的阈值相当于系数起草d,低于该合作行为发生;当耦合骑自行车者发散时,在第二阈值以上发生搭便车。这些行为也被假设出现在其他涉及节能机制的生物系统中。此外,组内合作和组间竞争之间的紧张关系与超有机体的性质是一致的。

英文摘要:

A theoretical framework for protocooperative behavior in pelotons (groups of cyclists) is proposed. A threshold between cooperative and free-riding behaviors in pelotons is modeled, together comprising protocooperative behavior (different from protocooperation). Protocooperative behavior is a function of: 1. two or more cyclists coupled by drafting benefit, 2. cyclists' current power output or speed, and 3. cyclists' maximal sustainable outputs (MSO). Characteristics of protocooperative behavior include: 1. relatively low speed phase in which cyclists naturally pass each other and share highest-cost front positions, and 2. free-riding phase in which cyclists maintain speeds of those ahead, but cannot pass. Threshold for protocooperative behavior is equivalent to coefficient of drafting d, below which cooperative behavior occurs; above which free-riding occurs up to a second threshold when coupled cyclists diverge. These behaviors are also hypothesized to emerge in other biological systems involving energy savings mechanisms. Further, the tension between intra-group cooperation and inter-group competition is consistent with superorganism properties.
