Female mate preference is central to sexual selection, and all indirect benefit models require that there is genetic variation in female preference. This has rarely been tested however, with relatively few studies documenting heritable variation in female preference and even fewer that have directly selected on mate preference to unequivocally show that it can evolve. Additionally, costs of mat...

Sexual selection theory suggests that choice for partners carrying dissimilar genes at the major histocompatibility complex (MHC) may play a role in maintaining genetic variation in animal populations by limiting inbreeding or improving the immunity of future offspring. However, it is often difficult to establish whether the observed MHC dissimilarity among mates drives mate choice or represent...

To Study or to Work? Education and Labour Market Participation of Young People in Poland This paper proposes Heckprobit estimates of the determinants of labour market participation of a sample of young (15-30) Poles, controlling for the sample selection bias caused by excluding those in education. There is evidence of sample selection bias in the case of young men, suggesting that they obey mor...

background: despite cultural and religious prohibitions against premarital heterosexual relationships and intimacy, some recent evidence suggests some rise in premarital heterosexual interactions and relationships among young people. on the other hand, although hiv in iran is a concentrated epidemic and mainly reported among high risk groups such as injecting drug users (idus), but there are ev...

Myth, Power, and Cyberspace: When faced with these three words, what image comes to mind? Could the world conceived in the popular science-fiction movie ‘The Matrix’ be a likely illustration? The enormous potential of the Internet is, to some extent, predicted in this movie by its subtle integration of Myth, Power, and Cyberspace. Such potential can also be seen from the all-around penetration ...

Human attractiveness is a potent social variable, and people assess their potential partners based on input from a range of sensory modalities. Among all sensory cues, visual signals are typically considered to be the most important and most salient source of information. However, it remains unclear how people without sight assess others. In the current study, we explored the relative importanc...

The increasing commercialisation and sophistication of language engineering products reinforces the need for tools and standards in support of a more cost-effective development and evaluation process than has been possible so far. This paper presents results of the MATE project which was launched in response to the need for standards and tools in support of creating, annotating, evaluating and ...
