The Software product line engineering is an inter-disciplinary concept. It spans the dimensions of business, architecture, process, and the organization. Similarly, Educational System engineering is also an inter-disciplinary concept, which spans the dimensions of academic, infrastructure, facilities, administration etc. Some of the potential requirements and benefits of this engineering approa...

Olfaction is an important sensory modality for mate recognition in many mammal species. Odorants provide information about the health status, genotype, dominance status and/or reproductive status. How and when odor profiles change during sexual maturation is, however often unclear, particularly in free-ranging mammals. Here, we investigated whether the wing sac odorant of male greater sac-winge...

Young athletes frequently suffer from being seen as athletes first and children second. This has consequences for their legal, civil and human rights as children (Kelly et al., 1995) and for the way in which sport organisations choose to intervene on their behalf to protect them from physical, psychological and sexual abuses (Brackenridge, 1994). Sport careers peak at different ages depending o...

AIMS The present study tested whether suboptimal priming (which may be defined as 'under viewing conditions rendering conscious identification highly improbable') with alcohol-related stimuli would activate existing expectancies about alcohol's effects on sexual desire. It was predicted that alcohol cues, relative to non-alcohol cues, would activate expectancies of alcohol's aphrodisiac propert...

hook worm (necator americanus) is one of the major pathogenic parasites in the north of iran. neonatal hamsters 1-3 days old showed a high degree of susceptibility to necator americanus infection and the parasite reached to sexually mature stages in six weeks following skin exposure. this method could be used for production of egg, larvae and adult worms. in this study neonatal hamsters were in...

Recent research suggested that the predictive validity of adult sexual offender risk assessment measures can be affected when used cross-culturally, but there is no published study on the predictive validity of risk assessment measures for youth who sexually offended in a non-Western context. This study compared the predictive validity of three youth risk assessment measures (i.e., the Estimate...

Among fruit-fly species of the genus Drosophila there is remarkable variation in sperm length, with some species producing gigantic sperm (e.g., > 10 times total male body length). These flies are also unusual in that males of some species exhibit a prolonged adult nonreproductive phase. We document sperm length, body size, and sex-specific ages of reproductive maturity for 42 species of Drosop...
