Overlapping Community

The iterative propagation of information between nodes will strengthen the connection strength between nodes, and the network can evolve into different groups according to difference edge strength. Based on this observation, we present the user engagement to quantify the influences of users different propagation modes to network propagation, and construct weight network to simulate real social network, and proposed the community detection method in social networks based on information propagation and user engagement. Our method can produce different scale communities and overlapping community. We also applied our method to real-world social networks. The experiment proved that the network spread and the community division interact with each other. The community structure is significantly different in the network propagation of different scales.

Conversion To Islam

AbstractBefore the civil war, conversion to Islam for Igbo men resident in the predominantly Hausa city of Kano in northern Nigeria usually meant becoming Hausa. More recent converts, however, have retained their Igbo identity and created an organisation, the Igbo Muslim Community. Three case studies from the first group detail the process and criteria of becoming Hausa, including immersion in Hausa economic and social networks; three case studies from the second group demonstrate that, while Hausa-centred networks remain important, converts have worked to construct new, Igbo-centred support structures. The watershed in the changing relationship between religious and ethnic affiliation for Igbo converts is the end of the war in 1970 and resultant changes in Igbo perceptions of Muslims, and changes in Igbo community structures.
