Degree of Separation in Social Networks [article]

Prerana Laddha
2010 arXiv   pre-print
We apply this approach to other random graphs depicting social networks and then compare the characteristics of these graphs with the average degree of separation.  ...  Social network analysis is the understanding of concepts and information on relationships among interacting units in an ecological system.  ...  A study of degree of separation in social networks can eventually have applications in other ecological networks.  ...

Inference for influence over multiple degrees of separation on a social network

Tyler J. VanderWeele
2013 Statistics in Medicine  
States and behaviors of different individuals are expected to be correlated across a social network.  ...  Christakis and Fowler have proposed a 'three degrees of influence rule' to characterize the extent of such dependence.  ...  However, importantly, in the context of only one degree of separation, if we are just interesting in testing for any social influence, then, under the null hypothesis of no contagion anywhere in the network  ...

Four Degrees of Separation, Really

P. Boldi, S. Vigna
2012 2012 IEEE/ACM International Conference on Advances in Social Networks Analysis and Mining  
We indulge in some reflections on the actual meaning of "average distance" and make a number of side observations showing that, yes, 3:74 "degrees of separation" are really few.  ...  We recently measured the average distance of users in the Facebook graph, spurring comments in the scientific community as well as in the general press [1].  ...  OF WEB AND SOCIAL GRAPHS AFTER REMOVING THE LARGEST (IN-)DEGREE NODES.  ...

Degrees of Separation, Social Learning, and the Evolution of Cooperation in a Small-World Network

Nicholas Seltzer, Oleg Smirnov
2015 Journal of Artificial Societies and Social Simulation  
We analyze a novel agent-based model of a social network in which agents make contributions to others conditional upon the social distance, which we measure in terms of the "degrees of separation" between  ...  Combining greater interaction distance with greater learning distance leads to a positive change in the total social welfare produced by the agents' contributions.  ...  In our unweighted social network, this social distance can be measured by means of the degrees of separation, defined here as the number of connections (edges) between any two agents (nodes).  ...

The Structure and Evolution of an Offline Peer-to-Peer Financial Network [article]

Pantelis Loupos, Alexandros Nathan
2018 arXiv   pre-print
We present a series of static and dynamic measurements that summarize the key aspects of any social network, namely the degree distribution, density and connectivity.  ...  We find that the degree distributions do not follow a power-law distribution, confirming previous studies that real-world social networks are rarely scale-free.  ...  Later on, a study 11 of the Facebook social graph found that the average degrees of separation are 4.5, claiming that online social networks have made the world much smaller.  ...

Model for simulating mechanisms responsible of similarities between people connected in networks of social relations [article]

Blazej Zak, Anita Zbieg
2014 arXiv   pre-print
It the literature have been identified three social mechanisms explaining the similarity between people connected in the network of social relations homophily, confounding and social contagion.  ...  The article proposes a simple model for simulating mechanisms responsible for similarity of attitudes in networks of social relations; along with a measure that is able to indicate which of the three mechanisms  ...  It says that each individual is influenced by their friends (1 st degree of separation), but also by friends of friends (2 nd degree of separation) and friends of friends' friends (3 rd degree of separation  ...

In addition, the average degrees of the separated neighbors approached the average network connectivity after approximately 3-4 steps.  ...  Social networks are often degree correlated between nearest neighbors, an effect termed homophily, wherein individuals connect to nearest neighbors of similar connectivity.  ...  Opinions, interpretations, conclusions, and recommendations are those of the author(s) and are not necessarily endorsed by the U.S. Army.  ...

Network ties are also more likely between people who give the same amount, and the similarity in cooperative behaviour extends up to two degrees of separation.  ...  Social networks display certain empirical regularities-in settings as diverse as villages, schools, and workplaces-in terms of variation in the degree distribution (number of social ties), transitivity  ...  But if social networks are a source of variation, then social proximity (measured separately for the campmate networks and gift networks by the inverse of the degrees of separation between two people)  ...
