Informe sobre el biaix de gènere en el reclutament, la retenció i la promoció a les universitats

Sistema d’indicadors sobre la situació de les dones al sistema universitari català. Des dels anys 60, hi ha consens a les societats desenvolupades sobre la necessitat de disposar d’estadístiques i indicadors fiables i comparables per garantir el seguiment de la I+D. Els indicadors sobre la situació de les dones són necessaris per facilitar i millorar la rendició de comptes de les universitats en relació al principi d’igualtat entre homes i dones. Els indicadors que avui es presenten estan en línia amb les polítiques i iniciatives europees, específicament en el marc de l’ERA que identifica la igualtat de gènere com una de cinc prioritats

Dynamics of sperm DNA fragmentation in the swine Ejaculate and temperature effects

The dynamics of sperm DNA fragmentation was examined in 16 boar ejaculates using the sperm chromatin dispersion (SCD) test and a two-tail comet assay. The net sperm rich fraction was preserved at two different temperatures (Trial 1 15 °C, n = 10; Trial 2 37 °C, n = 6) and sub-samples were taken every day until a sperm motility of zero. Significant differences in the dynamics of DNA fragmentation were observed among the different ejaculates and also according to the storage temperature. After analyzing the dynamic response of the sperm DNA damage, when the sperm samples are incubated at 15 or 37 °C, each ejaculate could be classified and a considerable variation among individuals for an increase in DNA damage was observed. Thus, while in some ejaculates no rise in DNA fragmentation was observed, in others, the sperm DNA fragmentation process was triggered during the initial days of the experiment. In general, sperm incubation at 37 °C diminished sperm DNA quality. The two-tail comet assay indicated that at time zero existing DNA damage mainly consisted of double stranded DNA breakage. During storage, DNA damage affected one of the DNA strands until a second wave of DNA damage, in which there was both single and double stranded DNA damage. © 2010 Elsevier B.V. All rights reserved

Sobre el aprendizaje de pesos en operadores de agregación: la media ponderada y operadores OWA

We study the determination of weights for two types of aggregation operators: the weighted mean and the OWA operator. We assume that there is at our disposal a set of examples for which the outcome of the aggregation operator is known. In the case of the OWA operator, we compare the results obtained by our method with another one in the literature. We show that the optimal weighting vector is reached with less cost.The author acknowledges partial support of the CICYT project SMASH (TIC96-1138-C04-04).Peer reviewe
