Floer cohomology of torus fibers and real lagrangians in Fano toric manifolds

In this article, we consider the Floer cohomology (with $\Z_2$ coefficients) between torus fibers and the real Lagrangian in Fano toric manifolds. We first investigate the conditions under which the Floer cohomology is defined, and then develop a combinatorial description of the Floer complex based on the polytope of the toric manifold. We show that if the Floer cohomology is defined, and the Floer cohomology of the torus fiber is non-zero, then the Floer cohomology of the pair is non-zero. We use this result to develop some applications to non-displaceability and the minimum number of intersection points under Hamiltonian isotopy.Comment: v2: Modified exposition and new corollary adde

Does Research Reduce Poverty? Assessing the Impacts of Policy?oriented Research in Agriculture

In the current context of the global financial crisis and its aftermath, development resources are likely to be getting scarcer. Resources for development research are too. The set of circumstances generating the resource scarcity is also putting pressure on development gains. More than ever before, every dollar spent on development will have to count towards sustainable poverty reduction, as will every dollar spent on development research. In light of this context this article asks what do we know about the welfare impacts of research in agriculture

Introducing Jus ante Bellum as a cosmopolitan approach to humanitarian intervention

Cosmopolitans often argue that the international community has a humanitarian responsibility to intervene militarily in order to protect vulnerable individuals from violent threats and to pursue the establishment of a condition of cosmopolitan justice based on the notion of a ‘global rule of law’. The purpose of this article is to argue that many of these cosmopolitan claims are incomplete and untenable on cosmopolitan grounds because they ignore the systemic and chronic structural factors that underwrite the root causes of these humanitarian threats. By way of examining cosmopolitan arguments for humanitarian military intervention and how systemic problems are further ignored in iterations of the Responsibility to Protect, this article suggests that many contemporary cosmopolitan arguments are guilty of focusing too narrowly on justifying a responsibility to respond to the symptoms of crisis versus demanding a similarly robust justification for a responsibility to alleviate persistent structural causes. Although this article recognizes that immediate principles of humanitarian intervention will, at times, be necessary, the article seeks to draw attention to what we are calling principles of Jus ante Bellum (right before war) and to stress that current cosmopolitan arguments about humanitarian intervention will remain insufficient without the incorporation of robust principles of distributive global justice that can provide secure foundations for a more thoroughgoing cosmopolitan condition of public right
