Evaluation of a German version of the Rivermead Mobility Index (RMI) in acute and chronic stroke patients

EUROPEAN JOURNAL OF NEUROLOGY, Issue 5 2000
M. R. Schindl
The English Rivermead Mobility Index (RMI) has been proposed as a simple, valid and reliable measure in stroke rehabilitation. A German version was established and validated in two centres. In centre A 46 acute (median: 3.0 days after onset) and in centre B 151 chronic (median: 88.0 days after onset) stroke patients participated. Interrater reliability of the German RMI was tested in 12 subjects in the acute stage of stroke and was found to be statistically significant (r = 0.98, P < 0.0001). In centre A, a statistically significant correlation was found between the German RMI and the 10-m walk time at baseline (r = 0.73, P < 0.0001) and after three weeks (r = 0.92, P < 0.0001). In centre B, the German RMI correlated significantly with the motor part of the Functional Independence Measure (motor-FIM) on admission (r = 0.78, P < 0.0001) and after three weeks (r = 0.79, P < 0.0001), respectively. The change of the RMI correlated significantly with the change in 10-m walk time in acute patients (r = 0.87, P < 0.0001) and with the change in motor-FIM in chronic patients (r = 0.54, P < 0.0001). A moderate ceiling-effect was detected in the chronic study population. The German RMI appears to be a reliable, valid and responsive measure for mobility disability in acute and chronic stroke patients. [source]

Partial Ordering of Unpredictable Mobility with Welfare Implications

ECONOMICA, Issue 299 2008
DANNY BEN-SHAHAR
We propose a partial ordering of ,unpredictable mobility' in the spirit of Blackwell's ordering of information structures. The proposed ordering ranks mobility matrices according to the degree to which elements in a given set are likely to move from one state to another, independently of their origin. Furthermore, for an important class of transition structures, our proposed ordering implies ordering, thus carrying significant welfare implications. Moreover, whenever it exists, our partial ordering functions as a sufficient condition for a class of renowned mobility measures and thereby generates, for a subset of transition matrices, unanimous ranking among mobility indices that are not generally consistent with one another.

What Lies Behind Income Mobility?

ECONOMICA, Issue 282 2004
Distributional Change in Belgium, Reranking, Western Germany, the USA
The paper presents a decomposition of income mobility indices into two basic sources: mobility induced by a change of the income distribution shape, and mobility induced by a reordering of individuals in the income pecking order. The decomposition procedure, based on counterfactual distributions, results in a decomposition that is applicable to a broad class of mobility measures. Application to income ,movement' indices with data for Belgium, Western Germany and the USA indicates that reranking has been the major force behind income mobility. [source]

European Enlargement and Agro-Food Trade

CANADIAN JOURNAL OF AGRICULTURAL ECONOMICS, Issue 4 2008
tefan Bojnec
This paper investigates the level, composition, and differences in the dynamics of revealed comparative advantage and trade specialization patterns of the 12 new member states (NMS-12) as part of the enlarged European Union 27 countries (EU-27). The NMS-12 are classified into four country groups: the Baltic States, the CEFTA-5, and the Mediterranean and the Balkan regions. The empirical analysis employs a regression framework, a duration analysis, Markov transition probability matrices, and mobility indices. Trade increases with the EU enlargement and so does revealed comparative advantage in agro-food products. There are catching-up difficulties, as indicated by revealed comparative advantage, in higher added-value processed products. Le présent article examine le degré, la composition et les différences de la dynamique des avantages comparatifs révélés ainsi que les caractéristiques de la spécialisation du commerce des douze nouveaux pays membres (NPM-12) de l'Union européenne élargie (UE,27). Les 12 nouveaux pays membres sont divisés en quatre groupes: les États baltiques, les cinq pays membres de l'ALECE, la région de la Méditerranée et la région des Balkans. L'analyse empirique utilise un modèle de régression, une analyse de durée, des matrices de probabilités des transitions (Markov) et des indices de mobilité. Les échanges augmentent avec l'élargissement de l'UE tout comme les avantages comparatifs révélés des produits agroalimentaires. On observe des difficultés de rattrapage, comme l'indique l'avantage comparatif révélé, dans le cas des produits transformés à forte valeur ajoutée. [source]
