We provide a generalization of the logistic two-sex model with ephemeral pair-bonds and with stable couples without assuming any specific mathematical form for fertility, mortality and the mating function. In particular, we establish a necessary and sufficient condition on the fertility/mortality density-dependent ratio that ensures the existence of the logistic behaviour. Several differences a…
The purpose of this paper is to introduce a 3R (right time, right place, and right material) principle for characterizing failure in humanitarian/relief supply chains’ response to natural disasters, and describes a Bayesian methodology of the failure odds with regard to external factors that may affect the disaster-relief outcome, and distinctive supply chain proneness to failure.
The purpose of this paper is to investigate optimal decision methods under a cooperative situation in two-echelon logistic models.
The paper aims to draw on rational choice theory (RCT) to explore factors underpinning the decision by female entrepreneurs in Nigeria to enter self-employment.
