RESUMO
By drawing from the engagement with the empirical case of sumud (Arabic: steadfastness) in Palestine, this article focuses on the social and political implications of everyday life in conflict settings. Proposing an alternative perspective on conflicts, this article argues that it is important also to focus on normalcy of everyday life in conflict settings and how this transforms conflict dynamics. Hence, contrary to the assumption that there is an opposition between the normalcy of everyday life and violent conflicts, this article argues that everyday life is not disrupted but that it goes on also in the face of conflicts, it only has to adapt to it. Building on Stephen Lubkemann's concept of 'culturally scripted life projects', this article will show how the attempt to pursue a regular life unfolds in an everyday setting in order to escape the predominant conflict/resistance frame. In addition to sumud as an individual practice this article highlights the broader social and political role this concept assumes in the context of Palestinian nationalism. In order to illustrate this argument, this article presents sumud as a spatial quotidian practice which is primarily aimed at realising culturally scripted life project in the face of the Israeli occupation.
RESUMO
In this paper we consider a system of non-linear integro-differential equations (IDEs) describing evolution of a clonally heterogeneous population of malignant white blood cells (leukemic cells) undergoing mutation and clonal selection. We prove existence and uniqueness of non-trivial steady states and study their asymptotic stability. The results are compared to those of the system without mutation. Existence of equilibria is proved by formulating the steady state problem as an eigenvalue problem and applying a version of the Krein-Rutmann theorem for Banach lattices. The stability at equilibrium is analysed using linearisation and the Weinstein-Aronszajn determinant which allows to conclude local asymptotic stability.
