A presente comunicação é o resultado de uma pesquisa bibliográfica e das constatações do autor derivadas da sua experiência no processo de ensino e aprendizagem, mormente na disciplina de Didáctica de Física. Tomando como pressuposto de que a Didáctica de Física ou a Prática de Ensino de Física, ocupa um papel preponderante no currículo de Formação do corpo discente e docente na Universidade Pedagógica, o autor trás à tona uma discussão teórica com vários autores que de algum tempo à esta (...) parte se têm debruçado sobre o assunto. Nesta discussão, o autor se apegou no seguinte tripé: a) A dicotomia ensino e aprendizagem em Física; b) A prática de ensino de Física: realidades e desafios rumo à novos paradigmas didáctico – epistemológicos e c) Algumas reflexões pessoais do autor, arraigadas na sua experiência profissional e não só. O desdobramento deste tripé, serviu para cimentar a sua convicção, antes tida como premissa, segundo a qual, o ensino de Física, sobretudo em se tratando de cursos universitários, a actividade experimental precisa ter em conta à aspectos como a descrição das aulas, o modo como são organizadas, a valorização das actividades experimentais desenvolvidas em pequenos grupos, bem como a abordagem que focaliza a demonstração de conceitos e fenómenos discutidos teoricamente. E ainda, o direccionamento das actividades para favorecer elementos didácticos como o desenvolvimento de habilidades, observação e interpretação, entre outros. Para que estes pressupostos ganhem eco na nossa plataforma curricular, é necessário que a formação de professores de Física, dê maior importância aos contornos ecológicos, sociais e económicos que bordejam o espaço educacional. A percepção teórica que isso dá ao educador, aglutinado ao saber teórico-prático deste, da realidade que circunda a escola, é a que dá ao educador, premissas e ferramentas para poder equacionar e apropriar-se com eficácia dos ambientes sócio-culturais existentes neste espaço ecológico.

The aim of this study was to investigate the role of discrete emotions in lexical processing and memory, focusing on disgust and fear. We compared neutral words to disgust-related words and fear-related words in three experiments. In Experiments 1 and 2, participants performed a lexical decision task, and in Experiment 3 an affective categorisation task. These tasks were followed by an unexpected memory task. The results of the LDT experiments showed slower reaction times for both types of negative words with (...) respect to neutral words, plus a higher percentage of errors, this being more consistent for fear-related words than for disgust-related words. Furthermore, only disgusting words exhibited a higher recall accuracy than neutral words in the memory task. Moreover, the advantage in memory for disgusting words disappeared when participants carried out an affective categorisation task during encoding, suggesting that the superiority in memory for disgusting words observed in Experiments 1 and 2 could be due to greater elaborative processing. Taken together, these findings point to the relevance of discrete emotions in explaining the effects of the emotional content on lexical processing and memory. (shrink)
In Subversive Spinoza , Antonio Negri spells out the philosophical credo that inspired his radical renewal of Marxism and his compelling analysis of the modern state and the global economy by means of an inspiring reading of the challenging metaphysics of the seventeenth-century Dutch-Jewish philosopher Spinoza. For Negri, Spinoza's philosophy has never been more relevant than it is today to debates over individuality and community, democracy and resistance, modernity and postmodernity.
Born in Granada, April 30, 1901, Antonio De Luna was educated in the universities of Granada and of Madrid, continued his studies at Freiburg in Bresgovia, Paris, and Oxford and received the doctorate in law from Bologna. At the age of 27 he was appointed to the chair of natural law at the University of La Laguna in the Canary Isles, and from there went on to Salamanca and Granada. In 1932 he obtained the chair of international public law (...) of the Faculty of Law of the University of Madrid. At this time he began a period of intense professional activity: He was Secretary of the Federation of Spanish Associations of International Studies (1932–1936), founder and director of the Institute of International and Economic Studies (1932–1936), and Secretary of the Juridical Assessory Commission of the Spanish Republic (1931–1934). After the interruption of the Civil War, Luna, with a sense of continuity, resumed his essential tasks. (shrink)
This article aims to review the standard objections to dualism and to argue that will either fail to convince someone committed to dualism or are flawed on independent grounds. I begin by presenting the taxonomy of metaphysical positions on concrete particulars as they relate to the dispute between materialists and dualists, and in particular substance dualism is defined. In the first section, several kinds of substance dualism are distinguished and the relevant varieties of this kind of dualism are selected. The (...) remaining sections are analyses of the standard objections to substance dualism : It is uninformative, has troubles accounting for soul individuation, causal pairing and interaction, violates laws of physics, is made implausible by the development of neuroscience and it postulates entities beyond necessity. I conclude that none of these objections is successful. (shrink)
In this paper we identify and characterize an analysis of two problematic aspects affecting the representational level of cognitive architectures (CAs), namely: the limited size and the homogeneous typology of the encoded and processed knowledge. We argue that such aspects may constitute not only a technological problem that, in our opinion, should be addressed in order to build arti cial agents able to exhibit intelligent behaviours in general scenarios, but also an epistemological one, since they limit the plausibility of the (...) comparison of the CAs' knowledge representation and processing mechanisms with those executed by humans in their everyday activities. In the fi nal part of the paper further directions of research will be explored, trying to address current limitations and future challenges. (shrink)
Decision Theory and Rationality offers a challenging new interpretation of a key theoretical tool in the human and social sciences. This accessible book argues, contrary to orthodoxy in politics, economics, and management science, that decision theory cannot provide a theory of rationality.

This book provides the first detailed account of Gramsci's work in the context of current critical and socio-cultural debates. Renate Holub argues that Gramsci was ahead of his time in offering a theory of art, politics and cultural production. Gramsci's achievement is discussed particularly in relation to the Frankfurt School (Adorno, Horkheimer, Benjamin, Bloch, Habermas), to Brecht's theoretical writings and to thinkers in the phenomenological tradition especially Merleau-Ponty. She argues for Gramsci's continuing relevance at a time of retreat from Marxist (...) positions on the postmodern left. Antonio Gramsci is distinguished by its range of philosophical grasp, its depth of specialized historical scholarship, and its keen sense of Gramsci's position as a crucial figure in the politics of contemporary cultural theory.

This study investigates the effects of internal and external corporate governance and monitoring mechanisms on the choice of corporate social responsibility (CSR) engagement and the value of firms engaging in CSR activities. The study finds the CSR choice is positively associated with the internal and external corporate governance and monitoring mechanisms, including board leadership, board independence, institutional ownership, analyst following, and anti- takeover provisions, after controlling for various firm characteristics. After correcting for endogeneity and simultaneity issues, the results show that (...) CSR engagement positively influences firm value measured by industry-adjusted Tobin’s q. We find that the impact of analyst following for firms that engage in CSR on firm value is strongly positive, while the board leadership, board independence, blockholders’ ownership, and institutional ownership play a relatively weaker role in enhancing firm value. Furthermore, we find that CSR activities that address internal social enhancement within the firm, such as employees diversity, firm relationship with its employees, and product quality, enhance the value of firm more than other CSR subcategories for broader external social enhancement such as community relation and environmental concerns.

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)
In _Michael Polanyi and His Generation_, Mary Jo Nye investigates the role that Michael Polanyi and several of his contemporaries played in the emergence of the social turn in the philosophy of science. This turn involved seeing science as a socially based enterprise that does not rely on empiricism and reason alone but on social communities, behavioral norms, and personal commitments. Nye argues that the roots of the social turn are to be found in the scientific culture and political events (...) of Europe in the 1930s, when scientific intellectuals struggled to defend the universal status of scientific knowledge and to justify public support for science in an era of economic catastrophe, Stalinism and Fascism, and increased demands for applications of science to industry and social welfare. At the center of this struggle was Polanyi, who Nye contends was one of the first advocates of this new conception of science. Nye reconstructs Polanyi’s scientific and political milieus in Budapest, Berlin, and Manchester from the 1910s to the 1950s and explains how he and other natural scientists and social scientists of his generation—including J. D. Bernal, Ludwik Fleck, Karl Mannheim, and Robert K. Merton—and the next, such as Thomas Kuhn, forged a politically charged philosophy of science, one that newly emphasized the social construction of science. (shrink)
In this article, we examine the empirical association between corporate governance (CG) and corporate social responsibility (CSR) engagement by investigating their causal effects. Employing a large and extensive US sample, we first find that while the lag of CSR does not affect CG variables, the lag of CG variables positively affects firms’ CSR engagement, after controlling for various firm characteristics. In addition, to examine the relative importance of stakeholder theory and agency theory regarding the associations among CSR, CG, and corporate (...) financial performance (CFP), we also examine the relation between CSR and CFP. After correcting for endogeneity bias, our results show that CSR engagement positively influences CFP, supporting the conflict-resolution hypothesis based on stakeholder theory, but not the CSR overinvestment argument based on agency theory. Furthermore, firms’ CSR engagement with the community, environment, diversity, and employees plays a significantly positive role in enhancing CFP. (shrink)
This book chapter shows how the early Heidegger’s philosophy around the period of Being and Time can address some central questions of contemporary social ontology. After sketching “non-summative constructionism”, which is arguably the generic framework that underlies all forms of contemporary analytic social ontology, I lay out early Heidegger’s conception of human social reality in terms of an extended argument. The Heidegger that shows up in light of this treatment is an acute phenomenologist of human social existence who emphasizes our (...) engagement in norm-governed practices as the basis of social reality. I then defuse a common and understandable set of objections against invoking the early Heidegger as someone who can make any positive contribution to our understanding of social reality. Lastly, I explore the extent to which the early Heidegger’s philosophy provides insights regarding phenomena of collective intentionality by showing how the intelligibility of such phenomena traces back to individual agents’ common understanding of possible ways of understanding things and acting with one another. With the early Heidegger, I argue that this common understanding is the fundamental source and basis of collective intentionality, not the non-summativist constructionism on which contemporary analytic social ontology has sought to focus with much effort. The lesson about social ontology that we should learn from the early Heidegger is that there is a tight connection between the social constitution of the human individual and his or her capacity to perform actions or activities that instantiate collective intentionality.

Roughly speaking, classical statistical physics is the branch of theoretical physics that aims to account for the thermal behaviour of macroscopic bodies in terms of a classical mechanical model of their microscopic constituents, with the help of probabilistic assumptions. In the last century and a half, a fair number of approaches have been developed to meet this aim. This study of their foundations assesses their coherence and analyzes the motivations for their basic assumptions, and the interpretations of their central concepts. (...) The most outstanding foundational problems are the explanation of time-asymmetry in thermal behaviour, the relative autonomy of thermal phenomena from their microscopic underpinning, and the meaning of probability. A more or less historic survey is given of the work of Maxwell, Boltzmann and Gibbs in statistical physics, and the problems and objections to which their work gave rise. Next, we review some modern approaches to (i) equilibrium statistical mechanics, such as ergodic theory and the theory of the thermodynamic limit; and to (ii) non-equilibrium statistical mechanics as provided by Lanford's work on the Boltzmann equation, the so-called Bogolyubov-Born-Green-Kirkwood-Yvon approach, and stochastic approaches such as `coarse-graining' and the `open systems' approach. In all cases, we focus on the subtle interplay between probabilistic assumptions, dynamical assumptions, initial conditions and other ingredients used in these approaches. (shrink)
The target article by Locke & Bogin (L&B) focuses on the evolution of language as a communicative tool. They neglect, however, that from infancy onwards humans have the ability to go beyond successful behaviour and to reflect upon language (and other domains of knowledge) as a problem space in its own right. This ability is not found in other species and may well be what makes humans unique.
This paper outlines a framework of the temporal interpretation in Chinese with a special focus on complement and relative clauses. It argues that not only does Chinese have no morphological tenses but there is no need to resort to covert semantic features under a tense node in order to interpret time in Chinese. Instead, it utilises various factors such as the information provided by default aspect, the tense-aspect particles, and pragmatic reasoning to determine the temporal interpretation of sentences. It is (...) shown that aspectual markers in Chinese play the same role that tense plays in a tense language. This result implies that the Chinese phrase structure has AspP above VP but no TP is above AspP. (shrink)
This article examines the empirical association between analyst coverage and corporate social responsibility (CSR) by investigating their simultaneous and causal effects, and its joint effects of CSR engagement and analyst coverage on firm risk. We find a positive association between the level and change of CSR engagement and the level and change of analyst coverage after considering simultaneity and causality. Based on the first-difference approach, we further find that the change in analyst following from the previous year affects the change (...) in CSR in the current period, whereas the change in CSR from the previous period does not influence the change in analyst following in the current period. Furthermore, we find that the change in CSR engagement as well as the interaction effect of changes in CSR and analyst coverage reduces the change of firm risk. When we examine the CSR strengths and concerns separately, analyst following does not significantly influence firms’ CSR strength but CSR concern activities decreases significantly as firms have more analyst followings. We further find the mediating role of financial analysts between CSR concerns (but not CSR strengths) and firm risk. We maintain that analysts provide indirect but additional social pressure to the firms to eventually reduce their irresponsible activities. Taken together, we interpret these results to support the stakeholder theory-based conflict-resolution explanation that considers CSR engagement as a vehicle to reduce conflicts of interest between managers and noninvesting stakeholders but not the overinvestment hypothesis that views CSR as a waste of valuable resources at the cost of shareholders.

The aim of this article is to analyse the relation between the second law of thermodynamics and the so-called arrow of time. For this purpose, a number of different aspects in this arrow of time are distinguished, in particular those of time-reversal (non-)invariance and of (ir)reversibility. Next I review versions of the second law in the work of Carnot, Clausius, Kelvin, Planck, Gibbs, Caratheodory and Lieb and Yngvason, and investigate their connection with these aspects of the arrow of time. It (...) is shown that this connection varies a great deal along with these formulations of the second law. According to the famous formulation by Planck, the second law expresses the irreversibility of natural processes. But in many other formulations irreversibility or even time-reversal non-invariance plays no role. I therefore argue for the view that the second law has nothing to do with the arrow of time.

Although argumentation plays an essential role in our lives, there is no integrated area of research on the psychology of argumentation. Instead research on argumentation is conducted in a number of separate research communities that are spread across disciplines and have only limited interaction. With a view to bridging these different strands, we first distinguish between three meanings of the word ?argument?: argument as a reason, argument as a structured sequence of reasons and claims, and argument as a social exchange. (...) All three meanings are integral to a complete understanding of human reasoning and cognition. Cognitive psychological research on argumentation has focused mostly on the first and second of these meanings, so we present perspectives on argumentation from outside of cognitive psychology, which focus on the second and third. Specifically, we give anoverview of the methods, goals, and disciplinary backgrounds of research on the production, the analysis, and the evaluation of arguments. Finally, inintroducing the experimental studies included in this special issue, which were conducted by researchers from a range of theoretical backgrounds, weunderline the breadth of argumentation research as well as stress opportunities for mutual awareness and integration.

We propose a nonmonotonic Description Logic of typicality able to account for the phenomenon of combining prototypical concepts, an open problem in the fields of AI and cognitive modelling. Our logic extends the logic of typicality ALC + TR, based on the notion of rational closure, by inclusions p :: T(C) v D (“we have probability p that typical Cs are Ds”), coming from the distributed semantics of probabilistic Description Logics. Additionally, it embeds a set of cognitive heuristics for concept (...) combination. We show that the complexity of reasoning in our logic is EXPTIME-complete as in ALC. (shrink)
