## Abstract The objective of this study is to compare physical performance measures for their ability to discriminate between levels of disability and disease severity in Parkinson's disease (PD). Disability in PD is commonly assessed by patient selfβreport, which may be limited by patient insight.

Abstract
This paper seeks to analyse tax performance across countries, utilizing what Musgrave (1969) referred to as the stochastic approach, where tax performance is analysed by comparisons with the average performance. The regression approach to tax performance assessment is used and a tax effort index is constructed. Among the variables that are identified to be important determinants of tax shares is a measure of tax evasion. The tax effort indices obtained show that generally the upper middleβincome and highβincome OECD groups are making better use of their tax bases to increase revenue. There are also economies of scale with respect to population density. Copyright Β© 2004 John Wiley & Sons, Ltd.

Reduction of the life cycle cost of aircraft is the main focus of aerospace material development at the moment. By improving the performance of aluminium alloys and using other material systems such as carbon fibre reinforced plastics (CFRP), the life cycle cost can be reduced. This paper presents a
This paper extends the portfolio choice model of tax evasion from a static to a dynamic setting. It is shown that while higher tax rates repress tax evasion in the static model, they encourage tax evasion in the dynamic model. We explore a novel implication of this result and show that while growth
