1. Respiratory syncytial virus seasonality in Brazil: implications for the immunisation policy for at-risk populations
Respiratory syncytial virus (RSV) infection is the leading cause of hospitalisation for respiratory diseases among children under 5 years old. The aim of this study was to analyse RSV seasonality in the five distinct regions of Brazil using time series analysis (wavelet and Fourier series) of the following indicators: monthly positivity of the immunofluoresc

2. 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

3. Changes in traffic law cause changes in the profile of traffic accidents? a gender analysis and frequency per week in the state of Piaui, 2001 A 2008 / Mudanças na legislação de trânsito provocam alteração no perfil dos acidentes de trânsito? uma análise de gênero e frequência semanal no estado do Piauí de 2001 A 2008
It is aimed to analyse if the Dry Law affected the profile of the accidents with victims, in the State of the Piauí. From the base of data extracted of the annual reports of the DETRAN, one intends to check if there were differences behaviours in the proportion of accidents for (feminine) type, and in the proportion of accidents that take place in the ends

4. Dinâmica populacional e efeitos de variáveis ambientais sobre a fauna de pequenos mamíferos em um fragmento de floresta com araucária no sul do Brasil
Natural populations of small rodents fluctuate continually over time and the population dynamics of any living organism are shaped by both intrinsic and extrinsic factors. Small mammals populations can show a continuum dynamic activity, ranging from stability to regular cycles of variable amplitude. The species dynamics is also known to be influenced by the

6. Accounting earnings properties and determinants of earnings response coefficient in Brazil / Propriedades do lucro contábil e determinantes do coeficiente de resposta ao lucro no Brasil
A fundamental issue at the interface of economics, finance, and accounting involves the relation between a firms reported earnings and its stock returns. The lack of research in this field using Brazilian data and the limitations of previous research in terms of time-series data (small length available) motivates the present research. In addition, the practi

9. Prediction of time series using architecture based on neuro-fuzzy systems. / Predição não-linear de séries temporais usando sistemas de arquitetura neuro-fuzzy.
This master dissertation has as main objetive applies systems of neuro-fuzzy architecture for functions prediction in serie times. The architecture carried out is the Adaptive Neuro-Fuzzy Inference System (ANFIS). This architecture is a kind of Fuzzy Inference Systems (FIS) implemen- tation under a paradigm of arti¯cial neural networks. Making use of techno

11. Estimação por maxima quase-verossimilhança no dominio do tempo de modelos de volatilidade estocastica com memoria longa
The aim of this work is to use of the Quasi-Maximum Likelihood estimator of Long Memory Stochastic Volatility models. The estimation by quasi-maximum likelihood is done in the time domain using an approximate state-space representation of the model. We analyse the autoregressive and moving average approximation using deferent maximum lag approximation. The r
