Too far ahead of its time: Barclays, Burroughs and real-time banking

The historiography of computing has until now considered real-time computing in banking as predicated on the possibilities of networked ATMs in the 1970s. This article reveals a different story. It exposes the failed bid by Barclays and Burroughs to make real time a reality for British banking in the 1960s

Human Security: Does Normative Europe Need a New Strategic Narrative?

Alongside a sustained debate about the role of the EU in the international system and the nature of its power as an external actor, foreign and security policy making continues to reflect an awkward mixture of civilian, military and normative instruments, and ambiguous goals. The European Security Strategy of 2003 and the drive, via ESDP, to make the EU respond more effectively to crises, are the most systematic attempts yet to resolve this incoherence and to project the EU as a different kind of international actor by deploying an integrated range of civilian and military capabilities and resources. This paper examines whether the EU also needs a new conceptual framework for its international presence which can organise and improve the integration of its civilian and military characteristics , and at the same time express to both its own citizens and the outside world, the values and goals which underpin its external action. The paper takes the concept of Human Security and explores whether a Human Security doctrine could provide a shared strategic narrative for the EU which would serve to clarify and consolidate the nature of EU actorness. The paper takes the example of the EU mission to DR Congo in 2006 to show how a Human Security doctrine could provide conceptual coherence to the exercise of EU external power

The t-Martin boundary of reflected random walks on a half-space

The t-Martin boundary of a random walk on a half-space with reflected boundary conditions is identified. It is shown in particular that the t-Martin boundary of such a random walk is not stable in the following sense : for different values of t, the t-Martin compactifications are not homeomorphic to each other.Comment: 13 pages, 1 figur

On zeros of Martin-L\"of random Brownian motion

We investigate the sample path properties of Martin-L\"of random Brownian motion. We show (1) that many classical results which are known to hold almost surely hold for every Martin-L\"of random Brownian path, (2) that the effective dimension of zeroes of a Martin-L\"of random Brownian path must be at least 1/2, and conversely that every real with effective dimension greater than 1/2 must be a zero of some Martin-L\"of random Brownian path, and (3) we will demonstrate a new proof that the solution to the Dirichlet problem in the plane is computable

An upper bound on the total inelastic cross-section as a function of the total cross-section

Recently Andr\'e Martin has proved a rigorous upper bound on the inelastic cross-section $\sigma_{inel}$ at high energy which is one-fourth of the known Froissart-Martin-Lukaszuk upper bound on $\sigma_{tot}$. Here we obtain an upper bound on $\sigma_{inel}$ in terms of $\sigma_{tot}$ and show that the Martin bound on $\sigma_{inel}$ is improved significantly with this added information.Comment: 4 page
