Predatory Pricing in a Oligopolistic Framework [PDF]

open access: yes, 1999
In this paper we study the nature of predatory behavior in an oligopolistic framework. We use the long-purse story of financial vulnerability to demonstrate that predatory behavior is less likely to occur in an oligopoly than in a monopoly.

Sentience in cephalopod molluscs: an updated assessment

open access: yesBiological Reviews, EarlyView.
ABSTRACT This article evaluates the evidence for sentience – the capacity to have feelings – in cephalopod molluscs: octopus, cuttlefish, squid, and nautilus. Our framework includes eight criteria, covering both whether the animal's nervous system could support sentience and whether their behaviour indicates sentience.

Some researchers consider these sequences to involve both semantics and syntax, while others argue that the sequences convey semantic information without syntax.

ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...
