Cross-border Movement of Patients in the EU: A Re-Appraisal

The national welfare state, so it seems, has come under attack by European integration. This article focuses on one facet of the welfare state, that is, health care and on one specific dimension, that is, cross-border movement of patients. The institution which has played a pivotal role in the development of the framework regulating the migration of patients is the European Court of Justice (ECJ). The Court’s activity in this sensitive area has not remained without critics. This was even more so since the Court invoked Treaty (primary) law which not only has made it difficult to overturn case law but also has left the legislator with very little room for manoeuvre in relation to any future (secondary) EU law. What is therefore of special interest in terms of legitimacy is the legal reasoning by which the Court has made its contribution to the development of this framework. This article is a re-appraisal of the legal development in this field.

Irish Credit Unions: Differential Regulation based on Business Model Complexity

This study examines the business model complexity of Irish credit unions using a latent class approach to measure structural performance over the period 2002 to 2013. The latent class approach allows the endogenous identification of a multi-class framework for business models based on credit union specific characteristics. The analysis finds a three class system to be appropriate with the multi-class model dependent on three financial viability characteristics. This finding is consistent with the deliberations of the Irish Commission on Credit Unions (2012) which identified complexity and diversity in the business models of Irish credit unions and recommended that such complexity and diversity could not be accommodated within a one size fits all regulatory framework. The analysis also highlights that two of the classes are subject to diseconomies of scale. This may suggest credit unions would benefit from a reduction in scale or perhaps that there is an imbalance in the present change process. Finally, relative performance differences are identified for each class in terms of technical efficiency. This suggests that there is an opportunity for credit unions to improve their performance by using within-class best practice or alternatively by switching to another class.

On the statistics of transverse permeability of randomly distributed fibers

An RVE–based stochastic numerical model is used to calculate the permeability of randomly generated porous media at different values of the fiber volume fraction for the case of transverse flow in a unidirectional ply. Analysis of the numerical results shows that the permeability is not normally distributed. With the aim of proposing a new understanding on this particular topic, permeability data are fitted using both a mixture model and a unimodal distribution. Our findings suggest that permeability can be fitted well using a mixture model based on the lognormal and power law distributions. In case of a unimodal distribution, it is found, using the maximum-likelihood estimation method (MLE), that the generalized extreme value (GEV) distribution represents the best fit. Finally, an expression of the permeability as a function of the fiber volume fraction based on the GEV distribution is discussed in light of the previous results.
