Democratic Participation, Engagement, and Freedom

It is commonly supposed that democracies should encourage greater political participation and civic engagement. This article identifies two distinct perspectives on political participation and civic engagement: a ‘freedom-centred’ model and an ‘ethical’ model. The ‘freedom-centred’ model defended here draws on the republican concept of freedom as non-domination, together with the political liberal notion of fair deliberative proceduralism, while the ethical model draws on Aristotelian, perfectionist, sources. It is argued that the ‘ethical’ model is overly concerned with the ‘moral renewal’ of modern social life, and is insensitive to problems of domination posed by its account of civic reciprocity and trust. By contrast, the ‘freedom-centred’ model developed offers a systematic account of personal and political freedom, which provides qualified support for deliberative modes of participation and engagement.

COLREGs-based collision avoidance strategies for unmanned surface vehicles

The aim of this paper is to report the preliminary development of an automatic collision avoidance technique for unmanned marine craft based on standardised rules, COLREGs, defined by the International Maritime Organisation. It is noted that all marine surface vessels are required to adhere to COLREGs at all times in order to minimise or eliminate the risk of collisions. The approach presented is essentially a reactive path planning algorithm which provides feedback to the autopilot of an unmanned vessel or the human captain of a manned ship for steering the craft safely. The proposed strategy consists of waypoint guidance by line-of-sight coupled with a manual biasing scheme. This is applied to the dynamic model of an unmanned surface vehicle. A simple PID autopilot is incorporated to ensure that the vessel adheres to the generated seaway. It is shown through simulations that the resulting scheme is able to generate viable trajectories in the presence of both stationary and dynamic obstacles. Rules 8 and 14 of the COLREGs, which apply to the amount of manoeuvre and to a head-on scenario respectively are simulated. A comparison is also made with an offline or deliberative grid-based path planning algorithm which has been modified to generate COLREGs-compliant routes.

Evidence and Spatial Planning for Sustainable Development: A Model for Spatially Allocating Material Flows

The aspiration the spatial planning should act as the main coordinating function for the transition to a sustainable society is grounded on the assumption that it is capable of incorporating both a strong evidence base of environmental accounting for policy, coupled with opportunities for open, deliberative decision-making. While there are a number of increasingly sophisticated methods (such as material flow analysis and ecological footprinting) that can be used to longitudinally determine the impact of policy, there are fewer that can provide a robust spatial assessment of sustainability policy. In this paper, we introduce the Spatial Allocation of Material Flow Analysis (SAMFA) model, which uses the concept of socio-economic metabolism to extrapolate the impact of local consumption patterns that may occur as a result of the local spatial planning process at multiple spatial levels. The initial application the SAMFA model is based on County Kildare in the Republic of Ireland, through spatial temporal simulation and visualisation of construction material flows and associated energy use in the housing sector. Thus, while we focus on an Ireland case study, the model is applicable to spatial planning and sustainability research more generally. Through the development and evaluation of alternative scenarios, the model appears to be successful in its prediction of the cumulative resource and energy impacts arising from consumption and development patterns. This leads to some important insights in relation to the differential spatial distribution of disaggregated allocation of material balance and energy use, for example that rural areas have greater resource accumulation (and are therefore in a sense “less sustainable”) than urban areas, confirming that rural housing in Ireland is both more material and energy intensive. This therefore has the potential to identify hotspots of higher material and energy use, which can be addressed through targeted planning initiatives or focussed community engagement. Furthermore, due to the ability of the model to allow manipulation of different policy criteria (increased density, urban conservation etc), it can also act as an effective basis for multi-stakeholder engagement.

A qualitative study of psychological, social and behavioral barriers to appropriate food portion size control

Background: Given the worldwide prevalence of overweight and obesity, there is a clear need for meaningful practical healthy eating advice - not only in relation to food choice, but also on appropriate food portion sizes. As the majority of portion size research to date has been overwhelmingly quantitative in design, there is a clear need to qualitatively explore consumers’ views in order to fully understand how food portion size decisions are made. Using qualitative methodology this present study aimed to explore consumers’ views about factors influencing their portion size selection and consumption and to identify barriers to appropriate portion size control.

Methods: Ten focus groups with four to nine participants in each were formed with a total of 66 persons (aged 19–64 years) living on the island of Ireland. The semi-structured discussions elicited participants’ perceptions of suggested serving size guidance and explored the influence of personal, social and environmental factors on their food portion size consumption. Audiotapes of the discussions were professionally transcribed verbatim, loaded into NVivo 9, and analysed using an inductive thematic analysis procedure.
Results: The rich descriptive data derived from participants highlight that unhealthy portion size behaviors emanate from various psychological, social and behavioral factors. These bypass reflective and deliberative control, and converge to constitute significant barriers to healthy portion size control. Seven significant barriers to healthy portion size control were apparent: (1) lack of clarity and irrelevance of suggested serving size guidance; (2) guiltless eating; (3) lack of self-control over food cues; (4) distracted eating; (5) social pressures; (6) emotional eating rewards;
and (7) quantification habits ingrained from childhood.

Conclusions: Portion size control strategies should empower consumers to overcome these effects so that the consumption of appropriate food portion sizes becomes automatic and habitual.

When does information about causal structure improve statistical reasoning?

Base rate neglect on the mammography problem can be overcome by explicitly presenting a causal basis for the typically vague false-positive statistic. One account of this causal facilitation effect is that people make probabilistic judgements over intuitive causal models parameterized with the evidence in the problem. Poorly defined or difficult-to-map evidence interferes with this process, leading to errors in statistical reasoning. To assess whether the construction of parameterized causal representations is an intuitive or deliberative process, in Experiment 1 we combined a secondary load paradigm with manipulations of the presence or absence of an alternative cause in typical statistical reasoning problems. We found limited effects of a secondary load, no evidence that information about an alternative cause improves statistical reasoning, but some evidence that it reduces base rate neglect errors. In Experiments 2 and 3 where we did not impose a load, we observed causal facilitation effects. The amount of Bayesian responding in the causal conditions was impervious to the presence of a load (Experiment 1) and to the precise statistical information that was presented (Experiment 3). However, we found less Bayesian responding in the causal condition than previously reported. We conclude with a discussion of the implications of our findings and the suggestion that there may be population effects in the accuracy of statistical reasoning.

Politics without the Vernacular: Liberal Culturalism and the Language Policy of the European Union

Will Kymlicka's liberal culturalism presents a tension between the idea that linguistic diversity in multilingual polities should be protected and the claim that democratic debate across linguistic boundaries is unfeasible. In this article, I resolve that tension by arguing that trans-lingual democratic deliberation in multilingual polities is necessary to legitimise those measures aimed at the protection of linguistic diversity. I conclude that my account provides a coherent normative response to the challenges faced by the European Union (EU) in the field of language policy and that an EU-wide deliberative forum is not as unfeasible as Kymlicka suggests.

The time course of conflict on the Cognitive Reflection Test

Reasoning that is deliberative and reflective often requires the inhibition of intuitive responses. The Cognitive Reflection Test (CRT) is designed to assess people’s ability to suppress incorrect heuristic responses in favour of deliberation. Correct responding on the CRT predicts performance on a range of tasks in which intuitive processes lead to incorrect responses, suggesting indirectly that CRT performance is related to cognitive control. Yet little is known about the cognitive processes underlying performance on the CRT. In the current research, we employed a novel mouse tracking mjavascript:void(0);ethodology to capture the time-course of reasoning on the CRT. Analysis of mouse cursor trajectories revealed that participants were initially drawn towards the incorrect (i.e., intuitive) option even when the correct (deliberative) option was ultimately chosen. Conversely, participants were not attracted to the correct option when they ultimately chose the incorrect intuitive one. We conclude that intuitive processes are activated automatically on the CRT and must be inhibited in order to respond correctly. When participants responded intuitively, there was no evidence that deliberative reasoning had become engaged.

Logic Brightens My Day: Evidence for Implicit Sensitivity to Logical Validity.

A key assumption of dual process theory is that reasoning is an explicit, effortful, deliberative process. The present study offers evidence for an implicit, possibly intuitive component of reasoning. Participants were shown sentences embedded in logically valid or invalid arguments. Participants were not asked to reason but instead rated the sentences for liking (Experiment 1) and physical brightness (Experiments 2-3). Sentences that followed logically from preceding sentences were judged to be more likable and brighter. Two other factors thought to be linked to implicit processing-sentence believability and facial expression-had similar effects on liking and brightness ratings. The authors conclude that sensitivity to logical structure was implicit, occurring potentially automatically and outside of awareness. They discuss the results within a fluency misattribution framework and make reference to the literature on discourse comprehension.

La parole en action : dissensus sur les accommodements raisonnables lors des auditions en commission parlementaire au Québec (2010-2011)

La question du pluralisme religieux est au Québec, l’objet de désaccords et de variations dans son mode de régulation et ses instruments d’action publique. La consultation publique sur le projet loi n° 94, Loi établissant les balises encadrant les demandes d’accommodement dans l’Administration gouvernementale et dans certains établissements, est au cœur de ceux-ci. En se basant sur l’analyse des séances d’auditions publiques en commission parlementaire qui ont eu lieu au Québec entre mai 2010 et janvier 2011 sur le projet de loi n° 94, cette thèse vise à interroger les enjeux liés à la publicisation des prises de positions et de l’échange d’arguments entre différents acteurs. À partir d’une méthodologie par théorisation enracinée et d’un cadre conceptuel qui se rattache à la communication publique, cette thèse cherche à mettre en évidence quelques-unes des propriétés des interactions verbales et non verbales qui composent et incarnent cette activité délibérative. Elle approche ces interactions du point de vue de leur publicisation en s’appuyant sur deux principes : la participation publique en tant qu’un instant de la construction du problème public et l’audition publique en commission parlementaire comme maillon d’un réseau dialogique qui participe à la publicisation du désaccord sur les accommodements raisonnables. Mettant l’accent sur l’usage du langage (verbal, non verbal et para verbal), l’objectif de cette thèse est de mieux comprendre comment des groupes minoritaires et majoritaires, engagés dans une arène publique où les points de vue par rapport aux accommodements raisonnables sont confrontés et mis en visibilité, gèrent leur situation de parole publique. La démarche de recherche a combiné deux stratégies d’analyse : la première stratégie d’inspiration conversationnelle, qui observe chaque séquence comme objet indépendant, a permis de saisir le déroulement des séances d’audition en respectant le caractère séquentiel des tours de parole La deuxième stratégie reviens sur les principaux résultats de l’analyse des séances d’auditions pour valider les résultats et parvenir à la saturation théorique pour élaborer une modélisation. L’exploitation des données selon cette approche qualitative a abouti au repérage de trois dynamiques. La première fait état des contraintes discursives. La seconde met en évidence le rôle des dimensions motivationnelles et socioculturelles dans la construction des positionnements et dans l’adoption d’un registre polémique. La troisième souligne la portée de la parole publique en termes d’actualisation des rapports de pouvoir et de confirmation de son caractère polémique. La modélisation proposée par cette thèse représente le registre polémique comme un élément constitutif de l’engagement argumentatif des acteurs sociaux mais qui est considérablement enchâssé dans d’autres éléments contextuels et motivationnels qui vont orienter sa portée. En tant qu’elle est exprimée dans un site dialogique, la parole publique en situation d’audition publique en commission parlementaire est en mesure de créer de nouvelles intrigues et d’une possibilité de coexister dans le dissensus. Le principal apport de cette thèse est qu’elle propose une articulation, concrète et originale entre une approche de la parole publique en tant que révélatrice d’autre chose que d’elle-même (nécessaire à tout éclaircissement des points de vue dans cette controverse) et une approche de la parole publique en tant que performance conduisant à la transformation du monde social. D’où, le titre de la thèse : la parole en action. Mots clefs : parole publique, discours, arène publique, pluralisme religieux, accommodements raisonnables, controverses, dissensus, théorisation enracinée

Qualified exceptionalism: the US Congress in comparative perspective

The framers of the American Constitution devised a singular bicameral legislative body, which invested substantial power in both a broadly representative lower chamber and a second "deliberative" chamber that was both insulated from the voters and unrepresentative of the population as a whole. Until the early 20th Century, the singular U.S. Congress changed little, but with growing national responsibilities, it sought to construct organizational forms that could address a consistently stronger executive. Since the 1980s, the Congress has relied increasingly on stronger parties to organize its activities. This development, embraced in turn by Democrats and Republicans, has led to changes that have edged the Congress in the direction of parliamentary democracies. We conclude this analysis has real, but limited utility, as congressional party leaders continue to barter for votes and, in the context, of narrow chamber majorities, often rely heavily on presidential assistance on divisive issues that are important to their party brand. Yet, the traditional features of the American separated system - bicameralism, the committee systems, and the centrifugal forces emanating from diverse congressional districts, increasingly complex policy issues, and the fear of electoral retribution - also remain strong, and effectively constrain the influence of leaders.'Qualified exceptionalism' thus most aptly describes the contemporary American Congress, which remains 'exceptional,' but less than unique, as it responds to many of the same forces, in some of the same ways (e.g., strong parties), as do many other representative assemblies around the world.

Ends, means, beginnings: environmental technocracy, ecological deliberation or embodied disagreement

Technocratic attitudes suggest that decisions about environmental policy should be led by scientific experts. Such decisions, it is expected, will be more rational than any arrived at by a democratic mediation between the narrow, short-term interests and uninformed preferences of the general public. Within green political theory, deliberative democracy has emerged as the dominant repost to technocracy, offering an account of how democratic polities can deal with complex scientific and technological decisions through the emergence of communicative rationality. This article argues that neither appeals to expert knowledge, nor communicative rationality, are likely to deliver the optimal green outcomes that proponents suggest, but rather will cover up the inevitable disagreements over environmental policy making. Instead the article suggests that more ecologically-sensitive and democratic decision making about complex scientific and technological issues can emerge if we acknowledge the differently embodied perspectives of decision-makers – from scientists to citizens. This prioritises democratic means over green ends, yet incorporates the environment at the beginning of the decision-making process. The article aims to sketch out the theoretical and practical implications of such an embodied turn for responding to the anti-democratic tendencies of environmental technocracy.
