In this article we present an advanced version of Dual-PECCS, a cognitively-inspired knowledge representation and reasoning system aimed at extending the capabilities of artificial systems in conceptual categorization tasks. It combines different sorts of common-sense categorization (prototypical and exemplars-based categorization) with standard monotonic categorization procedures. These different types of inferential procedures are reconciled according to the tenets coming from the dual process theory of reasoning. On the other hand, from a representational perspective, the system relies on the hypothesis of conceptual (...) structures represented as heterogeneous proxytypes. Dual-PECCS has been experimentally assessed in a task of conceptual categorization where a target concept illustrated by a simple common-sense linguistic description had to be identified by resorting to a mix of categorization strategies, and its output has been compared to human responses. The obtained results suggest that our approach can be beneficial to improve the representational and reasoning conceptual capabilities of standard cognitive artificial systems, and –in addition– that it may be plausibly applied to different general computational models of cognition. The current version of the system, in fact, extends our previous work, in that Dual-PECCS is now integrated and tested into two cognitive architectures, ACT-R and CLARION, implementing different assumptions on the underlying invariant structures governing human cognition. Such integration allowed us to extend our previous evaluation. (shrink)

During the last decades, many cognitive architectures (CAs) have been realized adopting different assumptions about the organization and the representation of their knowledge level. Some of them (e.g. SOAR [35]) adopt a classical symbolic approach, some (e.g. LEABRA[ 48]) are based on a purely connectionist model, while others (e.g. CLARION [59]) adopt a hybrid approach combining connectionist and symbolic representational levels. Additionally, some attempts (e.g. biSOAR) trying to extend the representational capacities of CAs by integrating diagrammatical representations and reasoning are (...) also available [34]. In this paper we propose a reflection on the role that Conceptual Spaces, a framework developed by Peter G¨ardenfors [24] more than fifteen years ago, can play in the current development of the Knowledge Level in Cognitive Systems and Architectures. In particular, we claim that Conceptual Spaces offer a lingua franca that allows to unify and generalize many aspects of the symbolic, sub-symbolic and diagrammatic approaches (by overcoming some of their typical problems) and to integrate them on a common ground. In doing so we extend and detail some of the arguments explored by G¨ardenfors [23] for defending the need of a conceptual, intermediate, representation level between the symbolic and the sub-symbolic one. In particular we focus on the advantages offered by Conceptual Spaces (w.r.t. symbolic and sub-symbolic approaches) in dealing with the problem of compositionality of representations based on typicality traits. Additionally, we argue that Conceptual Spaces could offer a unifying framework for interpreting many kinds of diagrammatic and analogical representations. As a consequence, their adoption could also favor the integration of diagrammatical representation and reasoning in CAs. (shrink)

The term etonism is from «Etona» that means flag, marks, evidence, and reason in Kikôngo. The variants in Umbûndu: etonolo or etonuilo means, allegations, reasons, indulgence (tolerance). The Nyaneka form is etŏnya: 1) reasons, 2) allegations, 3) indulgence and 5) the justice and the tolerance. Etona is Angolan artist (sculptor/painter). In his sculpture they are morphologically evidenced three treatments in the surface of the matter, namely 1) flat treatment; 2) rude treatment and finally 3) accidental treatment. Each one is a (...) code: #1. The flat treatment indicates well-knowledge; a man of superior class; race or tribe or religion of majority; thought well-organized and structured. In painting, the hot intensity indicates dominance, prosperity, energy, intense desires; #2. The rude treatment reveals an acquired knowledge without academism, self-taught; medium class men; speech out of the scientific perimeters but with certain admissibility; race, tribe or religion of lot of people, but not of majority. In his painting, the neutral intensity marks the balance and inspires recomfort nurtured from two opposed poles (hot and cold); #3. The accidental part of the sculpture indicates some knowledge’s lack (pure empiricism); inferior class; race, tribe, religion of minority. In the painting, the cold intensity is naturally contrary of #1. Etonism is the tolerant reason between #1=I, #2=YOU and #3=HE. All of them form the coherent society that we call WE: the Etonian jusphilosophy that African peoples need for stability of their democracies and finishing their War. (shrink)

We overview the main historical and technological elements characterising the rise, the fall and the recent renaissance of the cognitive approaches to Artificial Intelligence and provide some insights and suggestions about the future directions and challenges that, in our opinion, this discipline needs to face in the next years.

This paper investigates the influence of the increasingly sustainable sourcing policies of many multinational companies on suppliers located in developing countries. Our research was conducted in Viet Nam and involved 25 Vietnamese enterprises. The results reveal, on the one hand, how CSR makes business sense even in a developing country and, on the other hand, the difficulties of maintaining sustainability as products move from northern consumers to Vietnamese suppliers. In more detail, we highlight the unsustainable process through which corporate responsibility (...) is being imposed on Vietnamese suppliers and how CSR might eventually turn into a new form of protectionism. Therefore, this process calls for more collaborative models of governance among the companies along the supply chain, local authorities, international players, and civil society at large. (shrink)

Este artículo presenta una alternativa a la dicotomía entre razones motivacionales y razones normativas. En Practical Reality, Dancy mantiene que ambas razones se identifican con estados externos al agente--"tesis de la identidad" --. Hay dos argumentos en PR a favor de la TI: El primero se basa en una interpretación externista del significado de "tener una razón". El segundo presenta una vía indirecta, defendiendo que las adscripciones de razones según estados psicológicos internos no son casos centrales en las explicaciones normativas. (...) Estas dos críticas ignorarían una fuerte intuición normativa: el "acceso epistémico". Si ésta es persuasiva, los estados internos no pueden ser eliminables. /// This paper presents an alternative account to the dichotomy between normative and motivating reasons. In Practical Reality, Dancy argues that both types of reasons should be identified with external states of the agent--"identity thesis". There are two arguments in PR for the IT: one is based on an externalist interpretation of expressions like "A has a reason to x". The other is an indirect argument that claims that the ascription of reasons grounded on internal states cannot be central instances in normative explanations. Both arguments ignore a strong intuition: the "epistemic access". If this is a persuasive intuition, internal psychological states cannot be eliminated. (shrink)

On raconte qu'après la désignation comme Premier consul, Napoléon montra à des invités La Science de la législation de Gaetano Filangieri, le "jeune homme qui est notre maître à tous". Presque au même moment, ces volumes se trouvaient aussi sur le bureau de Benjamin Constant. La fortune et la circulation de cette oeuvre au sein de l'Europe des Lumières et du XIXe siècle sont l'objet de cet ouvrage, qui décrit les débats qu'elle a alimentés afin de comprendre pourquoi les hommes (...) de lettres et les politiques continuèrent à s'intéresser à ce classique de la pensée républicaine du XVIIIe siècle pour se fondre dans la nouvelle Europe du XIXe siècle."--Page 4 of cover.

Important sectors of research have been identified within the ambit of computers law, among these: the contracts for computer utilitation; the problem of the protection of ’software’; the protection of privacy with regard to informatics; the transborder data flow... In (...) the article are illustred the characteristics of these problems of computer law. (shrink)

Esta pesquisa avaliou o stress e as estratégias de coping em estudantes de uma universidade pública da região norte de Moçambique. Baseou-se na abordagem qualitativa e envolveu 28 estudantes de ambos os sexos, que cursavam o Curso de Licenciatura em Ensino de Filosofia, os quais responderam a uma entrevista semi-estruturada. A análise de conteúdo da informação coletada revelou a predominância de sintomas de stress de natureza psicológica e diversos estressores acadêmicos, nomeadamente: sobrecarga de matéria e de trabalhos acadêmicos, dificuldades financeiras (...) e econômicas, dificuldades na assimilação da matéria, más relações interpessoais, situações familiares, má atuação dos docentes e insucesso acadêmico. Para gerenciar o stress percebido os estudantes recorrem basicamente às estratégias paliativas. Os achados enfatizam a necessidade de delineamento e implementação de políticas institucionais de promoção de saúde mental dos estudantes, centradas na prevenção de stress e no aconselhamento psicológico.

The research in Human Computer Interaction (HCI) has nowadays extended its attention to the study of persuasive technologies. Following this line of research, in this paper we focus on websites and mobile applications in the e-commerce domain. In particular, we take them as an evident example of persuasive technologies. Starting from the hypothesis that there is a strong connection between logical fallacies, i.e., forms of reasoning which are logically invalid but psychologically persuasive, and some common persuasion strategies adopted within these (...) technological artifacts, we carried out a survey on a sample of 175 websites and 101 mobile applications. This survey was aimed at empirically evaluating the significance of this connection by detecting the use of persuasion techniques, based on logical fallacies, in existing websites and mobile apps. In addition, with the goal of assessing the effectiveness of different fallacy-based persuasion techniques, we performed an empirical evaluation where participants interacted with a persuasive (fallacy-based) and with a non-persuasive version of an e-commerce website. Our results show that fallacy-based persuasion strategies are extensively used in existing digital artifacts, and that they are actually effective in influencing users’ behavior, with strategies based on visual salience manipulation (accent fallacy) being both the most popular and the most effective ones.

The paradox marking Spinoza’s reappearance in modernity is well known. If Mendelssohn wished to “give him new credence by bringing him closer to the philosophical orthodoxy of Leibniz and Wolff,” and Jacobi, “by presenting him as a heterodox figure in the literal sense of the term, wanted to do away with him definitively for modern Christianity”—well, “both failed in their goal, and it was the heterodox Spinoza who was rehabilitated.” The Mendelssohn-Jacobi debate can be grafted onto the crisis of a (...) specific philosophical model. It generates a figure of Spinoza capable of assuaging the exacerbated spiritual tension of that epoch, and of constituting the systematic preamble of the relation between power and substance—between subject and nature. Spinoza, the damned Spinoza, had a resurgence in modernity as a Romantic philosopher. Lessing won out by recognizing in Spinoza an idea of nature which was capable of balancing the relation between feeling and intellect, freedom and necessity, and history and reason. Herder and Goethe, against the subjective and revolutionary impatience of the Sturm und Drang, based themselves on this powerful image of synthesis and recomposed objectivity: Spinoza is not only the figure of Romanticism; he constitutes its grounding and its fulfillment. The omnipotence of nature was no longer to break off into the tragedy of feeling, but it was to triumph over it, by opposing it to a kingdom of completed forms. Spinoza’s first reception within Romanticism was thus an aesthetic reception, a perception of motion and perfection, of dynamism and forms. And it remained such, even when the general frame and the particular components of Romanticism were subjected to the labor of philosophical critique. Fichte, the real philosophical hero of Romanticism, considered both Spinoza’s and Kant’s systems to be “perfectly coherent,” in the incessant ontological movement of the I. For the Schelling of the 1790s, the assertion of a radical opposition between 1 critical philosophy and dogmatic philosophy—that is, between a philosophy of the absolute I founding itself on the critical philosophy and a dogmatic philosophy of the absolute object and Spinozism—was quickly resolved into an analysis of action which dialectically took on the weight of the objective. Far from becoming antinomial, the absolute position of the I composes itself into a necessary process which, above tragedy, exalts the “spiritual automatism” of the relation between subject and substance. The aesthetic dimension of this synthesis consists in ceaselessly and tirelessly bringing back power and substance, the productive element and the form of production, to perfection. Romanticism, according to Hegel, is characterized by a capacity to overcome the pure objectivity of the ideal and the natural as a true idea of beauty and truth, initially to destroy the union of the idea and its reality, and to locate the latter in the difference, so as then to bring to manifestation the inner world of absolute subjectivity and reconstruct its objectivity where the overcoming of sensibility is appeased in the absolute character of the result. The filiation of this process is still Lessingian, but the new dialectic expresses and articulates its motivations, while insisting on the propaedeutic of the beautiful along the path leading to the absolute. Spinoza, a certain Spinoza, becomes the central figure in this process. (shrink)
