The Emergence of Norms via Contextual Agreements in Open Societies

This paper explores the emergence of norms in agents' societies when agents play multiple -even incompatible- roles in their social contexts simultaneously, and have limited interaction ranges. Specifically, this article proposes two reinforcement learning methods for agents to compute agreements on strategies for using common resources to perform joint tasks. The computation of norms by considering agents' playing multiple roles in their social contexts has not been studied before. To make the problem even more realistic for open societies, we do not assume that agents share knowledge on their common resources. So, they have to compute semantic agreements towards performing their joint actions. %The paper reports on an empirical study of whether and how efficiently societies of agents converge to norms, exploring the proposed social learning processes w.r.t. different society sizes, and the ways agents are connected. The results reported are very encouraging, regarding the speed of the learning process as well as the convergence rate, even in quite complex settings

Homo Socionicus: a Case Study of Simulation Models of Norms

This paper describes a survey of normative agent-based social simulation models. These models are examined from the perspective of the foundations of social theory. Agent-based modelling contributes to the research program of methodological individualism. Norms are a central concept in the role theoretic concept of action in the tradition of Durkheim and Parsons. This paper investigates to what extend normative agent-based models are able to capture the role theoretic concept of norms. Three methodological core problems are identified: the question of norm transmission, normative transformation of agents and what kind of analysis the models contribute. It can be shown that initially the models appeared only to address some of these problems rather than all of them simultaneously. More recent developments, however, show progress in that direction. However, the degree of resolution of intra agent processes remains too low for a comprehensive understanding of normative behaviour regulation.Norms, Normative Agent-Based Social Simulation, Role Theory, Methodological Individualism

Opinion dynamics: models, extensions and external effects

Recently, social phenomena have received a lot of attention not only from social scientists, but also from physicists, mathematicians and computer scientists, in the emerging interdisciplinary field of complex system science. Opinion dynamics is one of the processes studied, since opinions are the drivers of human behaviour, and play a crucial role in many global challenges that our complex world and societies are facing: global financial crises, global pandemics, growth of cities, urbanisation and migration patterns, and last but not least important, climate change and environmental sustainability and protection. Opinion formation is a complex process affected by the interplay of different elements, including the individual predisposition, the influence of positive and negative peer interaction (social networks playing a crucial role in this respect), the information each individual is exposed to, and many others. Several models inspired from those in use in physics have been developed to encompass many of these elements, and to allow for the identification of the mechanisms involved in the opinion formation process and the understanding of their role, with the practical aim of simulating opinion formation and spreading under various conditions. These modelling schemes range from binary simple models such as the voter model, to multi-dimensional continuous approaches. Here, we provide a review of recent methods, focusing on models employing both peer interaction and external information, and emphasising the role that less studied mechanisms, such as disagreement, has in driving the opinion dynamics.

Governance and the Processes of Inclusion/Exclusion: A Review of the Theory and Practice.

Governance identifies a discursive domain(Newman, 2002) in which both the policy and academic debate about new institutional configurations emerging from the proliferation of new forms of governing outside and beyond the state, is taking place My concern here is to highlight what I think is an under-theorised dimension in most of the perspectives from which the new forms of governance beyond the state are analysed. Specifically, I embrace Newman’s (2001) suggestion that most of the literature on Governance suffers from an under-theorisation of a “social†dimension of the analysis or, of what she terms the “politics of the wider public realm and the patterns of inclusion and exclusion on which it is based.†Using the above reflection as analytical starting point, this paper aims at showing how an important challenge for the field of Governance studies resides in the attempt to connect administrative and managerial issues with a broader set of issues concerning the nature of political participation in complex societes where not only the borders of the national states are blurred but the character of individual and collective identities is also relational and fluid. We will proceed first by critically reviewing from this perspective some of the current debates taking place in the Governance literature. Secondly by highlighting the concepts I consider fruitful to problematise the social dimension of the state-citizen relationship and to raise important questions with respect to the inclusionary and exclusionary practices on which it is based. And finally I will address the themes of inclusion and composition of consensus amidst diversity and complexity in the light of New Labour’s approach to Governance and, specifically, of its discourses of social inclusion, democratic renewal, networks and partnership governing.

An inter-disciplinary methodology for researching benefit-sharing as a norm diffusing in global environmental law

This paper proposes a methodology for an interdisciplinary, empirical enquiry into the diffusion of the legal concept of ‘benefit-sharing’. The paper draws together accounts of norm diffusion from sociology, international relations and law to devise a theoretical approach for the empirical research of global environmental law. Against this background, the paper explores the usefulness of process-tracing, the relevance of frames and the need for a participatory action research approach for a research project focused on benefit-sharing as a tool to operationalize equity among and within States

Reforming Institutions: Where to Begin?

Institutions promote growth—this view now holds firm ground. The task then is to ‘engineer’ growth promoting institutions. Endogeneity characterises institutions, for example, groups enjoying political power influence economic institutions but political power itself is a function of wealth. The question then is: what to reform first? History stands witness that generally the societies with extreme inequality and a heterogeneous population tend to evolve institutions that restrict access to economic opportunities for the poor which in turn constrains economic development. On the other hand societies with greater equality and homogeneous population typically enjoy growth-promoting institutions. Institutional reforms should therefore begin with institutions that serve to create or perpetuate inequality and heterogeneity in the society. We argue that the four different kinds of educational systems in operation in Pakistan are a major source of creating and perpetuating inequality and heterogeneity in the population. Access to a single and common educational system will open-up similar opportunities of higher education and job attainment for all the citizens, thereby reducing inequality. Diverse educational systems promote different sets of beliefs while a uniform system forges beliefconvergence in the society that in turn facilitates agreement on a common set of institutional reforms. Therefore it is the educational system that should be the first to reform. We also argue that in Pakistan, unlike some European countries in the 17th century, neither commercial interest nor fiscal constraints can force the de jure power to reform institutions. Typically, large commercial interests in Pakistan have thrived on favours from the de jure power and therefore have no interest in changing the system. Foreign aid eases the fiscal constraints from time to time relieving government of the need to reform institutions. The thought of a revolution of some kind is still a far cry, the society having no such inclination. The alternative then is the gradual approach preferred by North, Acemoglu and Rodrik. This gradual approach suggests the area of educational reforms.Institutional Evolution, Institutional Change, Human Behaviour
