  • cross level linkages in an ecology of climate change Adaptation Policy games
    Ecology and Society, 2018
    Co-Authors: Matthew Hamilton, Mark Lubell, Emilinah Namaganda
    Abstract:

    Social and ecological outcomes of environmental governance systems are shaped by interplay across the spatial levels at which Policy actors and decision-making forums operate. We focus on the conditions under which actors participate in Policy forums operating at higher or lower levels than the actors’ own level. We draw upon theories of network science and transaction costs to formulate and test predictions about the overall prevalence of such cross-level linkages as well as the conditions under which Policy actors engage in these linkages. We estimate an exponential random graph model using data collected from a survey of climate change Adaptation Policy actors participating in decision-making forums operating at different spatial levels within the Lake Victoria region in East Africa. Within this governance system, efforts to improve adaptive capacity across national boundaries and diverse vulnerable populations hinge on how well Policy forums operating at regional and higher levels attract the participation of actors with access to information about local conditions, the efficiency with which actors can disseminate funding and technical resources through more local Policy forums, as well as other processes that occur via cross-level linkages. We find that actors are less likely to engage in cross-level linkages compared to within-level linkages. Conditioning on this general tendency, actors are even less likely to participate in forums operating at lower levels in which their collaborators also participate. By contrast, actors are more likely to participate in forums operating at lower levels when influential actors jointly participate. These findings, which highlight distinct roles of social and political capital in cross-level forum participation, have implications for efforts to improve climate change Adaptation governance in the Lake Victoria region, as well as other multilevel governance systems.

  • a differential game approach to decentralized virus resistant weight Adaptation Policy over complex networks
    IEEE Transactions on Control of Network Systems, 2020
    Co-Authors: Yunhan Huang, Quanyan Zhu
    Abstract:

    Increasing connectivity of communication networks enables large-scale distributed processing over networks and improves the efficiency of information exchange. However, malware and a virus can take advantage of the high connectivity to spread over the network and take control of devices and servers for illicit purposes. In this paper, we use a susceptible–infected–susceptible epidemic model to capture the virus spreading process and develop a virus-resistant weight Adaptation scheme to mitigate the spreading over the network. We propose a differential game framework to provide a theoretic underpinning for decentralized mitigation in which nodes of the network cannot fully coordinate, and each node determines its own control Policy based on local interactions with neighboring nodes. We characterize and examine the structure of the Nash equilibrium, and discuss the inefficiency of the Nash equilibrium in terms of minimizing the total cost of the whole network. A mechanism design through a penalty scheme is proposed to reduce the inefficiency of the Nash equilibrium and allow the decentralized Policy to achieve social welfare for the whole network. We corroborate our results using numerical experiments and show that virus resistance can be achieved by a distributed weight Adaptation scheme.

    Abstract:

    Increasing connectivity of communication networks enables large-scale distributed processing over networks and improves the efficiency for information exchange. However, malware and virus can take advantage of the high connectivity to spread over the network and take control of devices and servers for illicit purposes. In this paper, we use an SIS epidemic model to capture the virus spreading process and develop a virus-resistant weight Adaptation scheme to mitigate the spreading over the network. We propose a differential game framework to provide a theoretic underpinning for decentralized mitigation in which nodes of the network cannot fully coordinate, and each node determines its own control Policy based on local interactions with neighboring nodes.

  • multi level governance and power in climate change Policy networks
    Global Environmental Change-human and Policy Dimensions, 2019
    Co-Authors: Monica Di Gregorio, Leandra Fatorelli, Jouni Paavola, Bruno Locatelli, Emilia Pramova, Dodik Ridho Nurrochmat, Peter H May, Maria Brockhaus
    Abstract:

    This article proposes an innovative theoretical framework that combines institutional and Policy network approaches to study multi-level governance. The framework is used to derive a number of propositions on how cross-level power imbalances shape communication and collaboration across multiple levels of governance. The framework is then applied to examine the nature of cross-level interactions in climate change mitigation and Adaptation Policy processes in the land use sectors of Brazil and Indonesia. The paper identifies major barriers to cross-level communication and collaboration between national and sub-national levels. These are due to power imbalances across governance levels that reflect broader institutional differences between federal and decentralized systems of government. In addition, powerful communities operating predominantly at the national level hamper cross-level interactions. The analysis also reveals that engagement of national level actors is more extensive in the mitigation and that of local actors in the Adaptation Policy domain, and specialisation in one of the climate change responses at the national level hampers effective climate Policy integration in the land use sector.
