Unmeasuring ourselves': Deleuze’s contributions for a psychology to come

This paper aims to introduce key Deleuzian concepts as they engage with the discipline of psychology. This will be done through an exploration of his work, in particular the two volumes of Capitalism and Schizophrenia co-written with Felix Guattari. As with Deleuze’s project itself, the paper has a critical element and a constructive one. Critically, it identifies the concerns that Deleuze alerts us in relation to the three main traditions within psychology (behaviourism, psychoanalysis and phenomenology) and provocatively introduces the notion of stupidity to signal the ways in which psychology has lost its intellectual horizon, by putting itself at the service of State and religious norms through a number of assumptions that are taken for granted, assumptions that constitute the silent and insidious common and good sense that holds the so called ‘rational project’ glued together in modern science.The second, more constructive, part aims to introduce key elements in Deleuze’s project as a way to engage with the possibilities that Deleuze brings to the discipline. The elements considered include a shift from an emphasis on epistemology to metaphysics, the centrality of difference (and variation) instead of identity (and stability), a shift to a relational type of knowledge rather than one that is representational and the articulation of the tensions between history and processes of emergence (becomings). Ultimately, the Deleuzian provocation to the discipline is to engage with a psychology to come through the articulation of a renewed and radical empiricism

Constant-factor approximations for Capacitated Arc Routing without triangle inequality

Given an undirected graph with edge costs and edge demands, the Capacitated Arc Routing problem (CARP) asks for minimum-cost routes for equal-capacity vehicles so as to satisfy all demands. Constant-factor polynomial-time approximation algorithms were proposed for CARP with triangle inequality, while CARP was claimed to be NP-hard to approximate within any constant factor in general. Correcting this claim, we show that any factor {\alpha} approximation for CARP with triangle inequality yields a factor {\alpha} approximation for the general CARP
