This article contrasts Mark Bevir’s approach to the history of ideas with a neoGramscian theory of discourse. Bevir puts the case for an ‘anti-foundationalist’ approach to understanding ideas, yet he defends a weak rationalism centred on individual intentions as the original source of all meanings. Discourse theorists specifically Ernesto Laclau and Chantal Mouffe also adopt an anti-foundationa...

The calculation of centrality measures is common practice in the study of networks, as they attempt to quantify the importance of individual vertices, edges, or other components. Different centralities attempt to measure importance in different ways. In this paper, we examine a conjecture posed by E. Estrada regarding the ability of several measures to distinguish the vertices of networks. Estr...

This article presents a randomized matrix-free method for approximating the trace of f(A), where A is large symmetric matrix and f function analytic in closed interval containing eigenvalues A. Our uses combination stochastic estimation (i.e., Hutchinson's method), Chebyshev approximation, multilevel Monte Carlo techniques. We establish general bounds on approximation error this by extending an...
