Wolves in sheep’s clothing: three new cases of aggressive mimicry in Red Sea coral reef fishes

ABSTRACT

Here we document three cases of mimicry in coral reef fishes not previously reported in the literature involving two groupers (Epinephelus leucogrammicus and Plectropomus marisrubri) and a soapfish (Diploprion drachi) as mimics, and two wrasses (Larabicus quadrilineatus and Cheilinus quinquecinctus) and a blenny (Meiacanthus nigrolineatus) as models. All three cases are of aggressive mimicry, with a predatory species mimicking a harmless one, and in one of the cases, the mimicry is also Müllerian, where both the predator and harmless species are unpalatable.

Creating Action Research Quality in Organization Development: Rigorous,Reflective and Relevant

The purpose of the paper is to present a framework that enables action researchers to create quality action research projects within the organization development (OD) domain using the broad criteria of being rigorous, reflective and relevant and so contribute to the realm of practical knowing. What constitutes good quality action research within OD is a difficult question, given the broad range of approaches that operates in a wide variety of settings and with great diversity. It advances specific dimensions by which action researchers can create, review and assess quality in action research work. This integrative framework and criteria are practical tools to enable action researchers to create quality action research in OD.     

Numerical Simulation of the COVID-19 Herd Immunity Based on Complex Network Modeling北大核心CSCD

鉴于构建流行病动力学模型、探索流行病传播规律对疫情防控具有十分重要的理论意义和实际应用价值,在已有的均匀混合模型基础上,针对个体接触关系异质化越发明显,且每个个体都处在不同的接触关系中,建立了兼顾个体状态与接触追踪的动态小世界网络模型。模拟了新冠病毒在社会中的传播过程。通过对比仿真结果,说明了所建模型的合理性。在此基础上,仿真计算了网络拓扑结构与接种免疫人数占比共同作用下对新冠病毒传播的影响,分析得到群体免疫临界值。说明所建传播模型合理,接种疫苗实现群体免疫可行。
