Sequential Deliberation for Social Choice

In large scale collective decision making, social choice is a normative study of how one ought to design a protocol for reaching consensus. However, in instances where the underlying decision space is too large or complex for ordinal voting, standard voting methods of social choice may be impractical. How then can we design a mechanism - preferably decentralized, simple, scalable, and not requiring any special knowledge of the decision space - to reach consensus? We propose sequential deliberation as a natural solution to this problem. In this iterative method, successive pairs of agents bargain over the decision space using the previous decision as a disagreement alternative. We describe the general method and analyze the quality of its outcome when the space of preferences define a median graph. We show that sequential deliberation finds a 1.208- approximation to the optimal social cost on such graphs, coming very close to this value with only a small constant number of agents sampled from the population. We also show lower bounds on simpler classes of mechanisms to justify our design choices. We further show that sequential deliberation is ex-post Pareto efficient and has truthful reporting as an equilibrium of the induced extensive form game. We finally show that for general metric spaces, the second moment of of the distribution of social cost of the outcomes produced by sequential deliberation is also bounded

Public crises, public futures

This article begins to map out a novel approach to analyzing contemporary contexts of public crisis, relationships between them and possibilities that these scenes hold out for politics. The article illustrates and analyses a small selection of examples of these kinds of contemporary scenes and calls for greater attention to be given to the conditions and consequences of different forms and practices of public and political mediation. In offering a three-fold typology to delineate differences between ‘abject’, ‘audience’ and ‘agentic’ publics the article begins to draw out how political and public futures may be seen as being bound up with how the potentialities, capacities and qualities that publics are imagined to have and resourced to perform. Public action and future publics are therefore analysed here in relation to different versions of contemporary crisis and the political concerns and publics these crises work to articulate, foreground and imaginatively and practically support

Equal Partners in Dialogue? Participation Equality in a Transnational Deliberative Poll (Europolis)

By gathering a representative sample of citizens from all 27 EU Member States, the deliberative poll Europolis created the opportunity for the inclusion of a wide variety of European voices. Taking up claims of difference democrats who argue that informal hurdles to participation can endure even after individuals gain formal access to the floor, this article argues for an extended approach to evaluate equality in deliberative minipublics. Specifically, it assesses whether participants contributed in roughly equal measures to the discussion and whether their discussion partners considered their contributions on equal merits. In doing so, the article adds to the small but growing literature on deliberation that expresses reservations about taking the willingness to engage with others' claims for granted. In order to account for the intrinsically relational aspect of interpersonal communication, measures of social network analysis are introduced as possible tools to evaluate participation equality in deliberative encounters

Ambient-aware continuous care through semantic context dissemination

Background: The ultimate ambient-intelligent care room contains numerous sensors and devices to monitor the patient, sense and adjust the environment and support the staff. This sensor-based approach results in a large amount of data, which can be processed by current and future applications, e. g., task management and alerting systems. Today, nurses are responsible for coordinating all these applications and supplied information, which reduces the added value and slows down the adoption rate. The aim of the presented research is the design of a pervasive and scalable framework that is able to optimize continuous care processes by intelligently reasoning on the large amount of heterogeneous care data. Methods: The developed Ontology-based Care Platform (OCarePlatform) consists of modular components that perform a specific reasoning task. Consequently, they can easily be replicated and distributed. Complex reasoning is achieved by combining the results of different components. To ensure that the components only receive information, which is of interest to them at that time, they are able to dynamically generate and register filter rules with a Semantic Communication Bus (SCB). This SCB semantically filters all the heterogeneous care data according to the registered rules by using a continuous care ontology. The SCB can be distributed and a cache can be employed to ensure scalability. Results: A prototype implementation is presented consisting of a new-generation nurse call system supported by a localization and a home automation component. The amount of data that is filtered and the performance of the SCB are evaluated by testing the prototype in a living lab. The delay introduced by processing the filter rules is negligible when 10 or fewer rules are registered. Conclusions: The OCarePlatform allows disseminating relevant care data for the different applications and additionally supports composing complex applications from a set of smaller independent components. This way, the platform significantly reduces the amount of information that needs to be processed by the nurses. The delay resulting from processing the filter rules is linear in the amount of rules. Distributed deployment of the SCB and using a cache allows further improvement of these performance results

From Creating Spaces for Civic Discourse to Creating Resources for Action

In this paper, we investigate the role of technology to address the concerns of a civil society group carrying out community-level consultation on the allocation of £1 million of community funds. We explore issues of devolved decision-making through the evaluation of a sociodigital system designed to foster deliberative virtues. We describe the ways in which this group used our system in their consultation practices. Our findings highlight how they adopted our technology to privilege specific forms of expression, ascertain issues in their community, make use of and make sense of community data, and create resources for action within their existing practices. Based on related fieldwork we discuss the impacts of structuring and configuring tools for ‘talk-based’ consultation in order to turn attention to the potential pitfalls and prospects for designing civic technologies that create resources for action for civil society

The geo-constitution: Understanding the intersection of geography and political institutions

This is the author accepted manuscript. The final version is available from SAGE Publications via the DOI in this record.This paper draws on existing work in the discipline of human geography and cognate fields in order to develop the concept of the ‘geo-constitution’. This concept aims to: (1) highlight the importance of intersections between geography and political institutions in the constitution of government; (2) consider the path-dependent development of political institutions and their impact on statecraft and citizenship; (3) explore the implications of this for political reform. The paper provides an overview of current thinking in political geography and applies the concept of the geo-constitution to the example of devolution and localism in the United Kingdom

“Democra-city”: bringing the city back into democratic theory for the 21st century?

Almost 50 years ago Robert Dahl maintained "we can […] reasonably hope 1 day to achieve great democratic cities. As the optimum unit for democracy in the 21st century, the city has a greater claim, I think, than any other alternative" (Am Polit Sci Rev 61: 953–970, 1967). This article intends to ascertain whether the words of one of the greatest scholars of democracy have had a concrete outcome along the pathways taken by democratic theory and whether, therefore, as was the case in classical theory, real superiority has therefore been restored to the city compared with the other territorial institutions of democracy. In this article we begin with two assumptions, each concerning the theoretical status of democratic theory. The first maintains that a realistic and an idealistic dimension coexist in variable dimensions in theoretical democratic models. According to the second assumption, it can be stated that democratic theory envisages the presence of a local territorial dimension, the importance of which is nevertheless variable in the different theoretical models. The thesis we intend to demonstrate here is that the variable nature of the importance of the local-urban territorial dimension depends on the type of balance created between the idealistic and realistic dimensions of the different models of democracy. Concluding, we aim to theoretically demonstrate why (and at which conditions) the city can become, more and better than any other institutional place, the ultimate arena within which the best results may be achieved for democracy in 21st century

Including the public in pandemic planning: a deliberative approach

Background: Against a background of pandemic threat posed by SARS and avian H5N1 influenza, this study used deliberative forums to elucidate informed community perspectives on aspects of pandemic planning. Methods: Two deliberative forums were carried out with members of the South Australian community. The forums were supported by a qualitative study with adults and youths, systematic reviews of the literature and the involvement of an extended group of academic experts and policy makers. The forum discussions were recorded with simultaneous transcription and analysed thematically. Results: Participants allocated scarce resources of antiviral drugs and pandemic vaccine based on a desire to preserve society function in a time of crisis. Participants were divided on the acceptability of social distancing and quarantine measures. However, should such measures be adopted, they thought that reasonable financial, household and psychological support was essential. In addition, provided such support was present, the participants, in general, were willing to impose strict sanctions on those who violated quarantine and social distancing measures. Conclusions: The recommendations from the forums suggest that the implementation of pandemic plans in a severe pandemic will be challenging, but not impossible. Implementation may be more successful if the public is engaged in pandemic planning before a pandemic, effective communication of key points is practiced before and during a pandemic and if judicious use is made of supportive measures to assist those in quarantine or affected by social isolation measures.Annette J Braunack-Mayer, Jackie M Street, Wendy A Rogers, Rodney Givney, John R Moss, Janet E Hiller, Flu Views tea

Deliberação online em consultas públicas? O caso da assembleia legislativa de Minas Gerais

Este artigo busca analisar uma consulta pública online sobre reforma política promovida em 2011 pela Assembleia Legislativa de Minas Gerais. Embasado pela teoria deliberacionista, o estudo de 752 posts guiou-se pela discussão de seis tópicos: (1) inclusividade; (2) provimento de razões; (3) reciprocidade; (4) respeito mútuo; (5) orientação para o bem comum; e (6) articulação entre arenas. Os resultados indicam: (1) uma sobrerepresentação de participantes masculinos e oriundos da Região Metropolitana de Belo Horizonte, embora não tenha havido concentração de posts em alguns comentadores; (2) o predomínio de posts on topic e que apresentam justificativas para as posições advogadas; (3) índices muito baixos de reciprocidade entre posts e de uso de marcadores de interatividade; (4) graus muito elevados de respeito; (5) diferentes formas de ligação das justificativas a ideias de bem comum; (6) o baixo impacto decisório e a conexão com outras arenas da esfera pública, destacando-se a relação com uma matéria publicada em jornal de grande circulação. Os achados são ambivalentes para os defensores da deliberação, indicando baixa probabilidade de deliberação interna ao fórum, mas algum potencial deliberativo quando se adotam lentes mais amplas. Os cruzamentos entre variáveis sugerem que as pessoas tendem a prover mais justificativas em discussões mais controversas, embora tendam a dialogar menos nesses casos. Assim, a hipótese da preferência por conversas entre like-minded encontra respaldo nos dados analisados
