The importance of kin relationships was investigated across adulthood with 5 samples (total N = 1,365). Within the personal networks, the genetic relatedness with relationship partners predicted subjective closeness (mean r = .50) and social support (mean r = .13). Effects were robust in 2 samples when controlling for residential proximity and contact frequency. These intraindividual correlatio...

Nepotism has been the primary influence on political behavior throughout human history. Despite the spread of democracy in the 20 century, nepotistic regimes have hardly disappeared. Nepotism heavily influences political activity throughout the developing world, Middle East, and central Asia where family ties are essentially for gaining access to power, state resources, and privileges. Rebellin...

Inclusive fitness theory, put forward by English biologist William Hamilton in 1964, is considered by many as the most important addition to the theory of natural selection since Darwin. One prediction of the theory is that animals should often show a tendency to nepotistically favour close relatives. Goodisman et al. (2007) test this theory for the first time using molecular methods in a vespi...

he aim of this study is to analyze the impact of nepotism on the employee performance and to find out what kind of a strategic move can be nepotism in the presence of such a relation. Although personnel selection through nepotism which is also known as family or acquaintance partiality causes a certain amount of disadvantages, it is possible at the same time to have more loyal employees to the ...

This paper summarizes results of simulation analyses aimed at elucidating the way in which two important dimensions of female rank orders-nepotism and age-gradedness-are affected by variation in individual strategies of rank acquisition on the one hand and by variation in population-wide demographic parameters (eg, birth rate, death rate, etc) on the other. Female rank orders in simulated prima...

Kin selected benefits of cooperation result in pronounced kin discrimination and nepotism in many social species and favour the evolution of sociality. However, low variability in relatedness among group members, infrequent competitive interactions with non-relatives, and direct benefits of cooperation may relax selection for nepotism. We tested this prediction in a permanently social spider, S...

0730-9384/2001/020203-13 © Association for Politics and the Life Sciences Abstract. The present discussion of sociobiological approaches to ethnic nepotism takes Pierre van den Bergheʼs theory as a starting point. Two points, which have not been addressed in former analyses, are considered to be of particular importance. It is argued that the behavioral mechanism of ethnic nepotism—as understoo...
