Coalition Structure Generation over Graphs [PDF]
We give the analysis of the computational complexity of coalition structure generation over graphs. Given an undirected graph G = (N,E) and a valuation function v : P(N) → R over the subsets of nodes, the problem is to find a partition of N into connected subsets, that maximises the sum of the components values.

Comparing Discourse and Policy Network Approaches: Evidence from Water Policy on Micropollutants
To understand how actors make collective policy decisions, scholars use policy and discourse network approaches to analyze interdependencies among actors.

Background Regulation of food environments is needed to address the global challenge of poor nutrition, yet policy inertia has been a problem. A common argument against regulation is potential conflict with binding commitments under international trade ...

Protest and Political Change in Ethiopia
Ethiopia was until recently perceived to be a strong state, with a coherent governing coalition party, the Ethiopian Peoples’ Revolutionary Democratic Front, dominated by its minority Tigrayan component party.

Complexity of coalition structure generation
We revisit the coalition structure generation problem in which the goal is to partition the players into exhaustive and disjoint coalitions so as to maximize the social welfare. One of our key results is a general polynomial-time algorithm to solve the problem for all coalitional games provided that player types are known and the number of player types

Solidarity in games with a coalition structure [PDF]
A new axiomatic characterization of the two-step Shapley value Kamijo (2009) is presented based on a solidarity principle of the members of any union: when the game changes due to the addition or deletion of players outside the union, all members of the union will share the same gains/losses.

We take a cross-layer optimization approach to study energy efficient data transport in coalition-based wireless sensor networks, where neighboring nodes are organized into groups to form coalitions and sensor nodes within one coalition carry out ...

The Two-Stage Game Approach to Coalition Formation: Where We Stand and Ways to Go
Coalition formation is often analysed in an almost non-cooperative way, as a two-stage game that consists of a first stage comprising membership actions and a second stage with physical actions, such as the provision of a public good.

‘Triage, transition, and transformation’: Advocacy discourse in urban school reform
Advocacy coalitions have the potential to be a vehicle for community-based education reform in urban school systems, where state legislatures have increasingly adopted top-down policies such as state takeover and accountability systems.
