Rising stars and sinking ships: consequences of status momentum.

Differences in rank are a ubiquitous feature of social life. Moving beyond the traditional static view of social hierarchy, five studies spanning multiple contexts examined how intertemporal changes in rank influenced people's status judgments. When final rank was held constant, people, products, and institutions were judged as higher status when they had arrived at this position by ascending, ...

A Quest for PMS candidate stars at low metallicity: Variable HAe/Be and Be stars in the Small Magellanic Cloud

We report the discovery of 5 new Herbig Ae/Be candidate stars in the Small Magellanic Cloud in addition to the 2 reported in Beaulieu et al. (2001). We discuss these 7 HAeBe candidate stars in terms of (1) their irregular photometric variability, (2) their near infrared emission, (3) their Hα emission and (4) their spectral type. One star has the typical photometric behaviour that is observed o...
