Background: The desire for universal health coverage in developing countries has brought attention to community-based health insurance (CBHI) schemes in developing countries. The government of Uganda is currently debating policy for the national health insurance programme, targeting the integration of existing CBHI schemes into a larger national risk pool. However, while enrolment has been larg...

Previous research suggests that preschool children expect members of social groups to share stable, inherent characteristics (e.g., Waxman, 2013). Here we explored the origins of these social-group based inferences by examining whether infants generalize food preferences across members of an arbitrary social group. Experiment 1 demonstrated that infants expected two individuals to share food pr...

In economics and social science, network data are regularly observed, a thorough understanding of the community structure facilitates comprehension economic patterns activities. Consider an undirected with n nodes K communities. We model using Degree-Corrected Mixed-Membership (DCMM) model, where for each node i=1,2,…,n, there exists membership vector πi=(πi(1),πi(2),…,πi(K))′, πi(k) is weight ...

During the past a few years, users’ membership in the online system (i.e. the social groups that online users joined) are wildly investigated. Most of these works focus on the detection, formulation and growth of online communities. In this paper, we study users’ membership in a coupled system which contains user-group and user-object bipartite networks. By linking users’ membership information...

This paper considers a permutation group G = 〈S〉 of degree n with t orbits such that the action on each orbit is primitive. It presents a O(tn2 logc(n)) time Monte Carlo group membership algorithm for some constant c. The algorithm is notable for its use of a new theorem showing how to find O(t log n) generators in O (̃|S|n) time under a more general form of the above hypotheses. The algorithm r...

In ad-hoc networks, the network nodes or users often form peer groups. The members of a group may share an application, a physical location, or administrative tasks. Defining who is a member of the group is also the first step towards establishing a shared secret key for secure communications. Group membership management involves adding and removing nodes in the group, as well as a method for a...

There has been an increasing interest in the use of inter-organisational groups to address regional implications in sustainable development. These groups bring together local knowledge and expertise and span boundaries between government and industry organisations. Our focus is in understanding how knowledge is shared in such inter-organisational groups. Utilising interviews, observations and s...

A growing body of research points to the value of multiple group memberships for individual well-being. However, much of this work considers group memberships very broadly and in terms of number alone. We conducted two correlational studies exploring how the relationship between multiple group membership and well-being is shaped by (a) the complexity of those groups within the overall self-conc...
