The acquisition of German plurals has been the focus of controversy in the last decade. In this paper we claim that degree of productivity (i.e. the capacity of nouns to form potential plurals) plays a key role in determining pace of acquisition. A plural elicitation task was administered to 84 Viennese German-speaking children aged 2;6 to 6;0. Analyses of correct responses showed that the high...

In this paper a statistical model of grain size distribution is proposed. It is su¢ ciently simple to be studied analytically. The resulting grain size distribution does not contain …tting parameters and describes reasonably well the experimental data. The statistical model is based on the suggested in the paper tessellation condition, the necessary and su¢ cient condition for a set of grains t...

❏ Diagnostic algorithm for patients with chronic productive cough outlined. A chronic 'productive' or 'wet' cough is a common presenting complaint for patients attending the adult respiratory clinic. Most reviews and guidelines suggest that the causes of a productive cough are the same as those of a non-productive cough and as such the same diagnostic pathway should be followed. Although it see...

Event sequences often contain continuous variability at different levels. In other words, their properties and characteristics change at different rates, concurrently. For example, the sales of a product may slowly become more frequent over a period of several weeks, but there may be interesting variation within a week at the same time. To provide an accurate and robust “view” of such multi-lev...
