The changes correspond to changes in the birth-rate. The former model of birth-rate which was characterized by the prevalence of legitimate children, child-bearing at a younger age and which ensured a change of generations, it was replaced by a new model characterized by having illegitimate children, the postponement of child-bearing, and low birth-rate, which does not ensure a change of generations. Although love relationships, marriage, and children are still considered to be the recognized values, these changes have affected the conception of child＇s education in the family and the perception of child as a value. It is therefore relevant to evaluate future spouses＇ preparation for a modern marriage and to constantly improve it. Such preparation is usually understood as young people＇s readiness far their first marriage. Readiness for the second marriage and child＇s education in the second family are no less important though still insufficiently explored empirically and theoretically generalized. This paper explores attitudes to child＇s education in the second marriage. The research was conducted inquiring people who wanted to create a family or establish long-term relationships. They were members of the online dating site ＂Harmonious Couple＂.展开更多

The food-for-sex hypothesis provides an explanation for the occurrence of food sharing among nonkin. However, little is known about the socio-ecological factors that can promote such a commodity exchange. A species mating system is a factor potentially influencing food-for-sex patterns of behavior. Here, we compared wolves, which form pair-bonds, with dogs, which are typically promiscuous in freeranging contexts, to investigate the effect of reproductive stages on the behavior around a food source in 2 different contexts. Furthermore, we considered the roles of both the males and the fe- males in the potential food-for-sex exchange. Results indicate that in both species and for both sexes the breeding period promotes decreased aggression. Additionally, females were more per- sistent in their attempts to access the food and were able to monopolize the resource more when in heat as compared to outside the breeding period. Finally, in dogs, but not wolves, females spent more time in proximity to the male＇s bone and had a shorter latency to start eating it when in heat. Overall, this study demonstrates that the food-for-sex hypothesis plays a part in intersexual food sharing in canids, and highlights the role of females in the interaction.
