Irlandés antiguo "·berar", umbro "ferar" y las desinencias medias indoeuropeas de tercera persona

[ES] Este trabajo se dedica fundamentalmente a revisar la interpretación usual de los tipos irlandés antiguo "·berar" y umbro "ferar" como provenientes de una forma originaria que es caracterizada por lo común como 3.ª sg. con desinencia medio-pasiva sin dental. Con este fin, se analizan las hipótesis hasta ahora propuestas, tanto en su vertiente formal como semántica (§§4-6), se valoran otras posibles explicaciones para formas de otras lenguas indoeuropeas que han sido aducidas como apoyo para tal reconstrucción (§§7-9) y, por último, se propone que el tipo irl.a. "·berar" es producto de una innovación céltica (insular) (§§10-19) y que no hay desinencias en "-r" sin dental en itálico (§§20-25).

A short training program improves the accuracy of portion-size estimates in future dietitians

[EN] The objective of this study was to determine whether a short training program, using real foods, would decreased their portion-size estimation errors after training. 90 student volunteers (20.18±0.44 y old) of the University of the Basque Country (Spain) were trained in observational techniques and tested in food-weight estimation during and after a 3-hour training period. The program included 57 commonly consumed foods that represent a variety of forms (125 different shapes). Estimates of food weight were compared with actual weights. Effectiveness of training was determined by examining change in the absolute percentage error for all observers and over all foods over time. Data were analyzed using SPSS vs. 13.0. The portion-size errors decreased after training for most of the foods. Additionally, the accuracy of their estimates clearly varies by food group and forms. Amorphous was the food type estimated least accurately both before and after training. Our findings suggest that future dietitians can be trained to estimate quantities by direct observation across a wide range of foods. However this training may have been too brief for participants to fully assimilate the application.
