The aim of this paper is to understand what a recession means for individual consumers, and to model in a life-cycle framework how individuals respond to recessions. Our focus is on the sharp increase in savings rates that have been observed in the current and recent recessions. We show empirically that these saving spikes were short-lived and common to all working age groups. We then study lif...

The concept of dependent random variables finds an important application in so-called time series, which are models of how a random quantity varies in time. In the case when time is discrete or discretized, as for example happens when one considers variables with daily, monthly or annual values (daily close of the stock market, monthly average temperatures, annual sales, score of i baseball gam...

We have implemented a weather forecasting system, WINDOM, which uses memorybased reasoning. The observation data from Japan Meteorological Agency's networks were used directly as input data and the system was used to predict the weather. We used 5 categories such as clear, clouded, rainy, snowy, stormy, or 2 categories such as rainy or not rainy, to describe Tokyo 6 hours ahead. Two weighting m...

The aim of this study was to compare testosterone concentration, body weight, scrotal circumference and age to penis detachment from days 30 to 240 in young Boer goat males (n = 22) born during the dry (n = 11) and the rainy (n = 11) seasons. In the dry season the parameters varied as follows: body weight from 3.7 ± 1.1 to 34.0 ± 4.7 kg, scrotal circumference from 7.9 ± 0.8 to 25.7 ± 2 cm, and ...

The present study examined occurrences of ectoparasites and identified them on dogs in rural regions in Brazil, and assessed the influence of climate on these parasites. Ectoparasites were randomly collected from 194 dogs living on farms located in Lavras (n = 92) and Nanuque (n = 102) during the dry season. During the subsequent rainy season, the same dogs in Lavras (n = 71) and Nanuque (n = 6...
