The Hyperon-Nucleon Interaction Potential in the Bound State Soliton Model: The ΛN\Lambda N Case

We develop the formalism to study the hyperon-nucleon interaction potential within the bound state approach to the SU(3) Skyrme model. The general framework is illustrated by applying it to the diagonal $\Lambda N$ potential. The central, spin-spin and tensor components of this interaction are obtained and compared with those derived using alternative schemes.Comment: source file, 4 ps figure

An Empirical Analysis of Inward Foreign Direct Investment Flows in the EU with Emphasis on the Market Enlargement Hypothesis*

We use a cross-section, time-series approach to study the determinants of foreign direct investment (FDI) in the European Union (EU) with particular emphasis on the expectations of a single market following the Single European Act of 1987. Using annual data from the 1980s and early 1990s, we investigate the determinants of US and Japanese FDI in the EU by pooling the data by the host country. We find strong evidence in favour of a single market effect where the anticipation of a larger market size due to a barriers free European market leads to an increase in the inflows of FDI. In addition, our estimation results show that FDI flows in the EU also depend on market size and the real exchange rate (as a proxy of relative labour costs). Copyright 1996 BPL.

How to do things with words : two seminars on the naming of functional (psychogenic, non-epileptic, dissociative, conversion, …) seizures

Amongst the most important conditions in the differential diagnosis of epilepsy is the one that manifests as paroxysms of altered behaviour, awareness, sensation or sense of bodily control in ways that often resemble epileptic seizures, but without the abnormal excessive or synchronous electrical activity in the brain that defines these. Despite this importance, there remains little agreement – and frequent debate – on what to call this condition, known inter alia as psychogenic non-epileptic seizures (PNES), dissociative seizures (DS), functional seizures (FS), non-epileptic attack disorder (NEAD), pseudoseizures, conversion disorder with seizures, and by many other labels besides. This choice of terminology is not merely academic – it affects patients’ response to and understanding of their diagnosis, and their ability to navigate health care systems.This paper summarises two recent discussions hosted by the American Epilepsy Society and Functional Neurological Disorders Society on the naming of this condition. These discussions are conceptualised as the initial step of an exploration of whether it might be possible to build consensus for a new diagnostic label
