Creencias de los Hombres y Mujeres Americanos sobre la Discriminación de Género: Para los Hombres, Esto No Es Precisamente un Juego de Suma Zero

We surveyed Americans regarding their beliefs about gender discrimination over the past several decades. Men and women agreed that women faced much more discrimination than men in the past, and they agreed that the discrimination gap between men and women has narrowed in recent years. However, men perceived the gap as narrower than women did at all time periods, and reported that there is little difference today in the amount of gender discrimination women and men face. Political ideology moderated these beliefs such that conservative men were most likely to report that anti-Man bias now equals or exceeds anti-Woman bias. Similar to recent research on beliefs about racism, these findings suggest that groups which differ historically in status and power exhibit perceptual differences regarding the changing nature of discrimination.Hemos realizado encuestas a personas americanas sobre sus creencias respecto a la discriminación de género durante las últimas décadas. Tanto hombres como mujeres estaban de acuerdo en que en el pasado las mujeres han sufrido mucha más discriminación que los hombres, y también en que esta diferencia se ha ido estrechando en los últimos años. Sin embargo, a los hombres esta diferencia siempre les ha parecido más estrecha que a las mujeres durante todos los periodos, y perciben que ahora hay pocas diferencias entre la discriminación que afrontan hombres y mujeres. Las ideologías políticas moderan estas creencias, de manera que los hombres conservadores son más propensos a afirmar que el sesgo anti masculino es igual o mayor al sesgo anti femenino. Al igual que algunas investigaciones recientes sobre las creencias respecto al racismo, nuestros hallazgos sugieren que grupos que difieren históricamente en estatus y poder perciben de forma diferente la naturaleza cambiante de la discriminación

Moral Judgments of the Powerless and Powerful in Violent Intergroup Conflicts

The present research examined observers\u27 moral judgments of groups in conflict. Study 1 found support for the prediction that actions are interpreted as more moral in the context of low power. People judged the violent actions of a fictitious group as more moral and justifiable when done by a smaller, less powerful country compared to a larger one. However, a second study found that violence may undermine the moral advantage accorded underdog groups. People reading about Israeli construction of settlements in Palestinian territories judged the Israeli actions to be more moral when Palestinians resisted violently compared to when they used non-violent resistance tactics. Together, these studies demonstrate how moral judgments of the actions of groups in conflict are influenced by contextual factors independent of the actions themselves

American Men’s and Women’s Beliefs about Gender Discrimination: For Men, It’s Not Quite a ZeroSum Game

The genetic bases for the variation in the liposaccharide of the mucosal pathogen, Campylobacter jejuni : biosynthesis of sialylated ganglioside mimics in the core oligosaccharide

We have compared the lipo-oligosaccharide (LOS) biosynthesis loci from 11 Campylobacter jejunistrains expressing a total of 8 different ganglioside mimics in their LOS outer cores. Based on the organization of the genes, the 11 corresponding loci could be classified into three classes, with one of them being clearly an intermediate evolutionary step between the other two. Comparative genomics and expression of specific glycosyltransferases combined with in vitro activity assays allowed us to identify at least five distinct mechanisms that allowC. jejuni to vary the structure of the LOS outer core as follows: 1) different gene complements; 2) phase variation because of homopolymeric tracts; 3) gene inactivation by the deletion or insertion of a single base (without phase variation); 4) single mutation leading to the inactivation of a glycosyltransferase; and 5) single or multiple mutations leading to \u201callelic\u201d glycosyltransferases with different acceptor specificities. The differences in the LOS outer core structures expressed by the 11 C. jejuni strains examined can be explained by one or more of the five mechanisms described in this work.Peer reviewed: YesNRC publication: Ye

High temperatures limit plant growth but hasten flowering in root chicory (Cichorium intybus) independently of vernalisation.

An increase in mean and extreme summer temperatures is expected as a consequence of climate changes and this might have an impact on plant development in numerous species. Root chicory (Cichorium intybus L.) is a major crop in northern Europe, and it is cultivated as a source of inulin. This polysaccharide is stored in the tap root during the first growing season when the plant grows as a leafy rosette, whereas bolting and flowering occur in the second year after winter vernalisation. The impact of heat stress on plant phenology, water status, photosynthesis-related parameters, and inulin content was studied in the field and under controlled phytotron conditions. In the field, plants of the Crescendo cultivar were cultivated under a closed plastic-panelled greenhouse to investigate heat-stress conditions, while the control plants were shielded with a similar, but open, structure. In the phytotrons, the Crescendo and Fredonia cultivars were exposed to high temperatures (35 °C day/ 28 °C night) and compared to control conditions (17 °C) over 10 weeks. In the field, heat reduced the root weight, the inulin content of the root and its degree of polymerisation in non-bolting plants. Flowering was observed in 12% of the heat stressed plants during the first growing season in the field. In the phytotron, the heat stress increased the total number of leaves per plant, but reduced the mean leaf area. Photosynthesis efficiency was increased in these plants, whereas osmotic potential was decreased. High temperature was also found to induce flowering of up to 50% of these plants, especially for the Fredonia cultivar. In conclusion, high temperatures induced a reduction in the growth of root chicory, although photosynthesis is not affected. Flowering was also induced, which indicates that high temperatures can partly substitute for the vernalisation requirement for the flowering of root chicor
