An evolutionary model explaining the Neolithic transition from egalitarianism to leadership and despotism.

The Neolithic was marked by a transition from small and relatively egalitarian groups, to much larger groups with increased stratification. But the dynamics of this remain poorly understood. It is hard to see how despotism can arise without coercion, yet coercion could not easily have occurred in an egalitarian setting. Using a quanti- tative model of evolution in a patch-structured population, we demonstrate that the interaction between demographic and ecological factors can overcome this conundrum. We model the co-evolution of individual preferences for hierarchy alongside the degree of despotism of leaders, and the dispersal preferences of followers. We show that voluntary leadership without coercion can evolve in small groups, when leaders help to solve coordination problems related to resource production. An example is coordinating construction of an irrigation system. Our model predicts that the transition to larger despotic groups will then occur when: 1. surplus resources lead to demographic expansion of groups, removing the viability of an acephalous niche in the same area and so locking individuals into hierarchy; 2. high dispersal costs limit followers' ability to escape a despot. Empirical evidence suggests that these conditions were likely met for the first time during the subsistence intensification of the Neolithic.

Rethinking the digital divide: from philanthropy to isonomia..

The digital divide has been, at least until very recently, a major theme in policy as well as interdisciplinary academic circles across the world, as well as at a collective global level, as attested by the World Summit on the Information Society. Numerous research papers and volumes have attempted to conceptualise the digital divide and to offer reasoned prescriptive and normative responses. What has been lacking in many of these studies, it is submitted, is a rigorous negotiation of moral and political philosophy, the result being a failure to situate the digital divide - or rather, more widely, information imbalances - in a holistic understanding of social structures of power and wealth. In practice, prescriptive offerings have been little more than philanthropic in tendency, whether private or corporate philanthropy. Instead, a theory of distributive justice is required, one that recovers the tradition of emancipatory, democratic struggle. This much has been said before. What is new here, however, is that the paper suggests a specific formula, the Rawls-Tawney theorem, as a solution at the level of analytical moral-political philosophy. Building on the work of John Rawls and R. H. Tawney, this avoids both the Charybdis of Marxism and the Scylla of liberalism. It delineates some of the details of the meaning of social justice in the information age. Promulgating a conception of isonomia, which while egalitarian eschews arithmetic equality (the equality of misery), the paper hopes to contribute to the emerging ideal of communicative justice in the media-saturated, post-industrial epoch.

Feedback Unbound: from master to usher.

A major theme of this book is that feedback should encourage dialogue; between students and lecturers, amongst peers and individually, as a form of self-critique and reflection. Here we endorse that theme but also propose an understanding of dialogue that goes beyond simple exchang or the presence of two or more voices. Inspired by Freire’s (1996) critical pedagogy we seek to make a link between the social nature of learning, the social nature of dialogue and the role of feedback as dialogue in a broader transformative learning process, and not merely as an adjunct to assessment.

from Webern to dance to Burton.

Commissioned by the Concorde Ensemble. Paul Roe gave the premiere performance at the RHA Gallery, Dublin, 23rd February 2014. The piece is informed by the choreography of Jiri Kylian, in particular two three minute sections of his work No More Play initially choreographed to a score by Webern (his Five Movements for String Quartet) hence the title.
