In this review, we present several variations of the Alpern-Reyniers two-sided matching model, with particular application to its biological interpretation as a mate selection game. In this context, the model describes equilibrium behavior in a dynamic game where unmated males and females of various types in a given cohort group are randomly matched in a succession of periods. If they 'accept' ...

Understory regeneration within canopy gaps in old-growth boreal forests may provide suitable habitat for wildlife typically associated with early-seral stages, leading to an increase in their abundance in late succession. We surveyed a chronosequence of postfire (17–265 years) and postharvest (3–63 years) stands in Canada’s eastern boreal forest to determine whether snowshoe hares (Lepus americ...

In this paper we study the enumeration and the construction, according to the number of ones, of particular binary words avoiding the fixed pattern p( j, i) = 1 j0i, 0 < i < j. The growth of such words can be described by particular jumping and marked succession rules. This approach enables us to obtain an algorithm which constructs all binary words having a fixed number of ones and then kills ...

This article investigates the implications of string theory for the conception of scientific theory confirmation. The classical understanding of theory confirmation is based on the assumption that scientific theory building is underdetermined by the available empirical data. Several arguments are presented, which suggest a devaluation of this ‘principle of scientific underdetermination’ in the ...

The E-learning represents the new frontier of education, significantly improving the learning process. In this paper we propose an e-learning model, providing both teachers and students with an open and modular learning environment. We then focus on courses personalization, both in terms of contents and teaching materials, according to each student s needs and capabilities, also taking teacher ...
