Sex-allocation conflict and sexual selection throughout the lifespan of eusocial colonies.

2018

AbstractModels of sex allocation conflict are central to evolutionary biology but have mostly assumed static decisions, where resource allocation strategies are constant over colony lifespan. Here, we develop a model to study how the evolution of dynamic resource allocation strategies is affected by the queen-worker conflict in annual eusocial insects. We demonstrate that the time of dispersal of sexuals affects the sex allocation ratio through sexual selection on males. Furthermore, our model provides three predictions that depart from established results of classic static allocation models. First, we find that the queen wins the sex allocation conflict, while the workers determine the max…

Hopfield Neural Network - Based Approach for Joint Dynamic Resource Allocation in Heterogeneous Wireless Networks

2006

This paper presents a comprehensive approach to solve the problem of joint dynamic resource allocation (JDRA) in heterogeneous wireless networks using a Hopfield neural network (HNN). A generic formulation for packet services with delay constraints is proposed to decide the optimal bit rate and radio access technology (RAT) allocation. Some illustrative simulations results in a basic scenario are presented to evaluate performance of the proposed algorithm.

Structural Growth Disengagement and value creation in small and micro-firms. Mapping pathologies and physiologies of business dwarfism in a dynamic r…

This paper focuses growth disengagement, in the perspective of those firms who have been keeping their structures, processes and relational systems unchanged for a very long time. The implicit hypothesis according to which such businesses are affected by a structural disease, are not able to create any significant value, and characterised by similar features, is critically discussed. Through an analysis of the phenomenon in the business growth and dynamic resource-based-view, a first attempt taxonomy, based on case-studies, is sketched. It is demonstrated how the implicit assumption according to which such firms are affected by a pathological condition is false, at least if seen as an a pri…
