    Cognitive networks: brains, internet, and civilizations

    Get PDF
    In this short essay, we discuss some basic features of cognitive activity at several different space-time scales: from neural networks in the brain to civilizations. One motivation for such comparative study is its heuristic value. Attempts to better understand the functioning of "wetware" involved in cognitive activities of central nervous system by comparing it with a computing device have a long tradition. We suggest that comparison with Internet might be more adequate. We briefly touch upon such subjects as encoding, compression, and Saussurean trichotomy langue/langage/parole in various environments.Comment: 16 page

    The philosophical significance of binary categories in Habermas’s discourse ethics

    Get PDF
    The philosophical programme associated with the discourse ethics of Jürgen Habermas has been widely discussed in the literature. The fact that Habermas has devoted a considerable part of his work to the elaboration of this philosophical programme indicates that discourse ethics can be regarded as a cornerstone of his communication-theoretic approach to society. In essence, Habermas conceives of discourse ethics as a philosophical framework which derives the coordinative power of social normativity from the discursive power of communicative rationality. Although there is an extensive literature on Habermas’s communication-theoretic account of society, almost no attention has been paid to the fact that the theoretical framework which undergirds his discourse ethics is based on a number of binary conceptual divisions. It is the purpose of this paper to shed light on the philosophical significance of these binary categories in Habermas’s discourse ethics and thereby demonstrate that their complexity is indicative of the subject’s tension-laden immersion in social reality

    E-democracy as the frame of networked public discourse : information, consensus and complexity

    Get PDF
    The quest for democracy and the political reflection about its future are to be understood nowadays in the horizon of the networked information revolution. Hence, it seems difficult to speak of democracy without speaking of e-democracy, the key issue of which is the re-configuration of models of information production and concentration of attention, which are to be investigated both from a political and an epistemological standpoint. In this perspective, our paper aims at analyzing the multi-agent dimension of networked public discourse, by envisaging two competing models of structuring this discourse (those of dialogue and of claim) and by suggesting to endorse the epistemic idea of complementarity as a guidance principle for elaborating a form of partnership between traditional and electronic media

    Sensemaking on the Pragmatic Web: A Hypermedia Discourse Perspective

    Get PDF
    The complexity of the dilemmas we face on an organizational, societal and global scale forces us into sensemaking activity. We need tools for expressing and contesting perspectives flexible enough for real time use in meetings, structured enough to help manage longer term memory, and powerful enough to filter the complexity of extended deliberation and debate on an organizational or global scale. This has been the motivation for a programme of basic and applied action research into Hypermedia Discourse, which draws on research in hypertext, information visualization, argumentation, modelling, and meeting facilitation. This paper proposes that this strand of work shares a key principle behind the Pragmatic Web concept, namely, the need to take seriously diverse perspectives and the processes of meaning negotiation. Moreover, it is argued that the hypermedia discourse tools described instantiate this principle in practical tools which permit end-user control over modelling approaches in the absence of consensus

    Effects of Syntactic Complexity in Discourse Comprehension

    Get PDF
    This study aimed to evaluate the effects of syntactic complexity in discourse comprehension in persons with aphasia (pwa) and age-matched controls.  Data suggest that syntactic complexity does influence processing at the discourse level and that heuristic processing alone is not enought to compensate for syntactic processing demands in disourcse.  Results also showed that the Test of Syntacitc Effects in Discourse Comprehension (Levy et al, 2010) is sensitive to syntactic complexity in a way that the Discourse Comprehension Test-Revised (Brookshire and Nicholas, 2008) is not

    What makes up good consultations? A qualitative study of GPs' discourses

    Get PDF
    Background: In medical literature, several principles that define 'good consultations' have been outlined. These principles tend to be prescriptive in nature, overlooking the complexity of general practitioners (GPs)' perspectives of everyday practice. Focusing on perspectives might be particularly relevant, since they may affect decisions and actions. Therefore, the present study adopts a bottom-up approach, analyzing GPs' narratives about 'good' and 'bad' consultations. We aimed at describing the range of discourses GPs use in relating on their practice. Methods: Semi-structured interviews were conducted with 19 Belgian GPs. By means of a qualitative analysis, the authors mapped patterns in the interview narratives and described the range of different discourses. Results: Four discourses were identified: a biomedically-centered discourse, a communication-focused discourse, a problem-solving discourse and a satisfaction-oriented discourse. Each discourse was further specified in terms of predominant themes, problems the GPs prefer to deal with and inherent difficulties. Although most participants used elements from all four discourses, the majority of the GPs relied on an individual set of predominant discourses and focused on a limited number of themes. Conclusion: This study clearly indicates that there is no uniform way in which GPs perceive clinical practice. Each of the participants used a subtle mix of different criteria to define good and bad medical consultations. Some discourse elements appear to be rooted in medical literature, whereas others are of a more personal nature. By focusing on the limitations of each discourse, this study can shed new light on some of the difficulties GPs encounter in their daily practice: being confronted with specific problems might be an effect of adhering to a specific discourse. The typification of different discourses on consultations may function as a framework to help GPs reflect on how they perceive their practice, and help them manage some of the challenges met in daily practice

    Collaborative Epistemic Discourse in Classroom Information Seeking Tasks

    Get PDF
    We discuss the relationship between information seeking, and epistemic beliefs – beliefs about the source, structure, complexity, and stability of knowledge – in the context of collaborative information seeking discourses. We further suggest that both information seeking, and epistemic cognition research agendas have suffered from a lack of attention to how information seeking as a collaborative activity is mediated by talk between partners – an area we seek to address in this paper. A small-scale observational study using sociocultural discourse analysis was conducted with eight eleven year old pupils who carried out search engine tasks in small groups. Qualitative and quantitative analysis were performed on their discussions using sociocultural discourse analytic techniques. Extracts of the dialogue are reported, informed by concordance analysis and quantitative coding of dialogue duration. We find that 1) discourse which could be characterised as ‘epistemic’ is identifiable in student talk, 2) that it is possible to identify talk which is more or less productive, and 3) that epistemic talk is associated with positive learning outcomes
