The explosion of people networking in cyberspace, disseminating terabytes of information is being promoted through the use of broadband, bluetooth technology, and wireless mobile computing facilities such as laptops, PDA’s and now smart-phones. New communities within such venues as virtual chat rooms, Forums, e-classrooms videoconferences, discussion groups, newsgroups etc. are being created da...

INTRODUCTION Ever since the idea was first espoused by Darwin in his classic The Descent of Man and Selection in Relation to Sex [Darwin, 1871], the evolutionary importance of sexual selection has been documented within a multitude of species. Comparatively few studies, however, have focused on the impact of sexual selection on populations of naturally occurring hybrid animals, or hybrid zones,...

the present paper aimed at assessing the effects of young people’s indicators of life skills. the theoretical foundation of this research was obtained from adler’s and the world health organization’s viewpoints on life skill and mental health. the method of this study was a survey (applied, descriptive and correlation), and the sample group consisted of young people aged 15-29 in hajiabad town ...

change the interests of young people toward communicating in cyberspace, using mobile phone and sms communications is a threat in the some critics’ point of view, which can be an opportunity to learn anytime, anywhere. mobile learning is an approach to targeted nourishing of curious minds of technology generation in the wireless communication world. thus, this study toward establishing the grou...

In many animals, sexual selection on male traits results from female mate choice decisions made during a sequence of courtship behaviors. We use a bower-building cichlid fish, Nyassachromis cf. microcephalus, to show how applying standard selection analysis to data on sequential female assessment provides new insights into sexual selection by mate choice. We first show that the cumulative selec...

Study of the genetic and developmental architecture of mate preferences lags behind the study of sexual ornaments. This is in part because of the challenges involved in describing mate preferences, which are expressed as a function of variation in ornaments. We used the function-valued approach to test for genetic and environmental components of variation in female mate preferences in Enchenopa...

Previous studies on sex-differentiated mate preferences have focused on univariate analyses. However, because mate selection is inherently multidimensional, a multivariate analysis more appropriately measures sex differences in mate preferences. We used the Mahalanobis distance (D) and logistic regression to investigate sex differences in mate preferences with data secured from participants res...

The mutation-selection hypothesis may extend to understanding normal personality variation. Traits such as emotional stability, agreeableness, and conscientiousness figure strongly in mate selection and show evidence of non-additive genetic variance. They are linked with reproductively relevant outcomes, including longevity, resource acquisition, and mating success. Evolved difference-detection...
