1. Aging related responses to conflicting proprioceptive and visual information about initial position during reaching
INTRODUCTION: The purpose of the current study was to examine whether age-related differences are exhibited in the relative contributions of vision and proprioception with initial hand position to the control of movement distance of single-joint reaching movements. METHODS: We use a virtual reality display to systematically change the relationship between th

2. Evaluating the existence of structural change in the brazilian term structure of interest : evidence based on cointegration models with structural break
This paper investigates whether there is evidence of structural change in the Brazilian term structure of interest rates. Multivariate cointegration techniques are used to verify this evidence. Two econometrics models are estimated. The rst one is a Vector Autoregressive Model with Error Correction Mechanism (VECM) with smooth transition in the deterministi

4. Wage determinants in Spain (1980-2000)
This paper provides evidence about the nominal wage determinants in Spain during the period 1980-2000. We estimate a wage equation, using time series analysis applying an error correction mechanism. Our aim is to analyse the extent to which the evolution of wages is influenced by the unemployment, prices and productivity. The results reveal that the unemploy

5. Equações de oferta e demanda por exportações do Brasil: um estudo comparativo do setor de madeira e móveis
This dissertation is about the estimation of export equations for both Brazilian total economy and Brazilian wood-furniture sector, using quarterly data, from 1985 to 2006. The econometric procedures use the Johansens co-integration concept associated to an error-correction model. Special attention is dedicated to a possible problem of instability in paramet

6. Effectiveness analysis of statics and dynamics hedge strategies for Brazilian arabian coffee market / Análise da efetividade das estratégias estáticas e dinâmicas de hedge para o mercado brasileiro de café arábica
This work was the purpose of analyzing the hedge strategies effectiveness, in terms of risks reduction to the arabian coffee market, with the futures markets use. It was observed, a priori, that arabian coffee is among the most risky products of the Brazilian agribusiness. Moreover, it was detected low use of futures mechanism not only for this product, but

7. ESTIMAÇÃO DE EQUAÇÕES DE EXPORTAÇÕES POR SETORES: UMA INVESTIGAÇÃO SOBRE O IMPACTO DO CÂMBIO / ESTIMATION OF EXPORT EQUATIONS BY SECTORS: A RESEARCH ON EXCHANGE RATE IMPACT
The aim of this dissertation is to investigate the impact of the exchange rate in several export sectors of the brazilian economy, throughout the use of uniequation econometric models. In particular, we make use of the autoregressive distributed lags model (ADL) to obtain the long run exchange rate elasticities. The short run dynamics is obtained by use of a

8. Probing the principles of amino acid selection using the alanyl-tRNA synthetase from Escherichia coli.
The alanyl-tRNA synthetase from Escherichia coli activates cysteine, alpha-aminobutyrate and other-noncognate amino acids that are larger than alanine so slowly that no editing mechanism is required for error correction. Serine, however, is activated sufficiently rapidly that an editing mechanism is required to remove the products of misactivation. The disti

9. Statistical evaluation and biological interpretation of non-random abundance in the E. coli K-12 genome of tetra- and pentanucleotide sequences related to VSP DNA mismatch repair.
The abundance of all tetra- and pentanucleotide sequences is calculated for a set of DNA sequence data comprising 767,393 nucleotides of the E. coli K-12 genome. Observed frequencies are compared to those expected from a Markov chain prediction algorithm. Systematic and extreme non-random representations are found for special sets of sequences. These are int

10. Response of vitamin B-6 deficiency and the carpal tunnel syndrome to pyridoxine.
The specific activities and percentage deficiencies of the glutamic oxaloacetic transaminase of erythrocytes (EGOT) were determined for patients with carpal tunnel syndrome (CTS) diagnosed by clinical examination and electrical conduction data; the EGOT data revealed a severe deficiency of vitamin B-6. After double-blind treatment with pyridoxine and placebo

11. Hypermutation in bacteria and other cellular systems.
A temporary state of hypermutation can in principle arise through an increase in the rate of polymerase errors (which may or may not be triggered by template damage) and/or through abrogation of fidelity mechanisms such as proofreading and mismatch correction. In bacteria there are numerous examples of transient mutator states, often occurring as a consequen
