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.

INCONTINENCE, HONOURING SUNK COSTS AND RATIONALITY According to a basic principle of rationality, the decision to engage in a course of action should be determined solely by the analysis of its consequences. Thus, considerations associated with previous use of resources should have no bearing on an agent’s decision-making process. Frequently, however, agents persist carrying on an activity they themselves judge to be nonoptimal under the circumstances because they have already allocated resources to that activity. When this is the case, agents (...) are said to be honouring sunk costs. Honouring sunk costs is thus typically viewed as irrational economic behaviour. Two striking findings of the psychological literature on the sunk cost effect are that it is, in general, not lessened by having taken previously courses in economics, and that agents who did take such courses and that do honour sunk costs seem to be frequently aware of a cognitive dissonance in their behaviour. Davidson’s account of the possibility conditions of incontinent action renders continent action materially unfeasible. The very idea of incontinent action becomes thus a hollow one. I’ll present an alternative description of these possibility conditions that renders continent action materially feasible, and both, continent and incontinent action, cognitively plausible. In a nutshell, my proposal rests upon the drawing of an essential cognitive contrast between explicit processes of deliberative reasoning and lower level heuristic procedures. I conclude the paper arguing that my redescription of incontinent action accounts for the above mentioned cognitive dissonance effect better than the alternatives and that viewing at least an important subset of behaviours of honouring sunk costs as incontinent actions will enable us to consider them as peculiar manifestations of a more general and meaningful pattern in human behaviour.

English summary: According to a current prejudice, the God of reason does not have a home in Protestantism. On the basis of model studies on the connection between biblical, Platonic and Aristotelian themes in the development of the Christian concept of God in late antiquity, the Middle Ages and the Renaissance, the authors of this volume show that the reformers did not at all flatly dismiss the rationality of faith. The articles focus on the modern transformations of the concept of (...) God in the 18th and 19th centuries. The volume, a collection of case studies of the history of the problem of the Christian concept of God, concludes with prominent syntheses of revelation and reason in the 20th century. German description: Einem gangigen Vorurteil zufolge hat der Gott der Vernunft im Protestantismus keine Heimat. Nach exemplarischen Studien zur Verbindung von biblischen mit platonischen und aristotelischen Motiven bei der Entfaltung des christlichen Gottesgedankens in Spatantike, Mittelalter und Renaissance zeigt der vorliegende Band aber, dass die Reformatoren der Vernunft des Glaubens keineswegs pauschal den Abschied gaben. Der Schwerpunkt der Beitrage liegt auf den neuzeitlichen Transformationen des Gottesgedankens im 18. und 19. Jh. Prominente Synthesen von Offenbarung und Vernunft im 20. Jh. schliessen den Band ab, der Fallstudien zu einer Problemgeschichte des christlichen Gottes-Denkens versammelt.

Antonio Negri wrote the two essays that comprise Time for Revolution while serving a prison sentence for alleged involvement with radical left-wing groups. Although the essays were written two decades apart, their concerns are the same: is there a place for resistance in a society utterly subsumed by capitalism? In the wake of the global crisis of capitalism heralded by the 2008 crash, the question has never been more relevant and Negri remains an insightful and passionate guide to any attempt (...) to answer it.

Psychiatric diagnoses such as Autism Spectrum Disorder (ASD) are primarily attributed on the basis of behavioral criteria. The aim of most of the biomedical research on ASD is to uncover the underlying mechanisms that lead to or even cause pathological behavior. However, in the philosophical and sociological literature, it has been suggested that autism is also to some extent a ‘social construct’ that cannot merely be reduced to its biological explanation. We show that a one-sided adherence to either a biological (...) or a social explanation leads to a moral dilemma, a Catch-22, for autistics and for those living with them. Such explanations close the space for self-identifying as autistic and at the same time being considered to be in good mental health. They foreclose the possibility of making sense of the lived experience of (and with) autistics. In this paper we argue that such lack of space for moral imagination inherently leads to scientific stalemate. We propose that one can only go beyond this stalemate by taking an ethical stance in theorizing, one that enables better intersubjective understanding. Only on such a view can behavior and biology be linked without either disconnecting them or reducing the one to the other. (shrink)

Uma tese fundamental para a tradição cristã é a de que _todas as coisas que acontecem no mundo acontecem sob a providência divina. _Assim, também o sofrimento dos seres humanos precisa ser compreendido à luz da noção de providência, e o sofrimento de um justo como Jó ou de uma comunidade humana inteira como os escravos no Brasil colonial parece especialmente desconcertante. Uma interpretação recente enfatiza a função terapêutica das adversidades. Contudo, uma visão cuidadosa de alguns textos de Tomás de (...) Aquino e de Antônio Vieira apontam para a limitação humana quanto à plena compreensão da providência divina bem como para a imprescindibilidade da fé na providência de Deus. (shrink)

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.

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.

In the scholium to proposition 49 of Part 2 of the Ethics, Spinoza addresses a number of prejudices that tend to obscure the essentially judgmental nature of ideas. One warning is issued against those who do not distinguish accurately between ideas and images, and, for this exact reason, fail to see that every idea, insofar as it is an idea, always involves an affirmation that something is the case. This paper shows that in order to properly understand Spinoza's remarks in (...) this passage, we must redirect attention to Descartes’ Meditations on First Philosophy, and more particularly to the objections raised against them by Hobbes. Specifically, I argue for the identification of Hobbes and other likeminded “imagists” as Spinoza's main targets, and not, as is often assumed, Descartes himself or Cartesians in general. My identification not only resolves interpretative confusion surrounding this passage, but it also confirms Spinoza's commitment to a key rationalist assumption: the existence of a mind that can grasp or exhibit natures by clear and distinct perceptions. While both adequate and inadequate ideas are necessitated beliefs or judgments in which we assent to something, virtue consists in being propelled by the intellect. (shrink)

This article aims to propose some connections between the conceptions of poetry of the Mexican poet Octavio Paz and the German philosopher Martin Heidegger. Both see in poetry the element of recognition of the original condition of the human being, not as an interpretation, but as a perception and affectation of the existential reality of human beings. So that the event of the "poetic saying" is configured as a call to the possibility of glimpsing the being of each entity, inhabiting (...) oneself and, thus, learning to be with others, establishing the poetic field as the clearing of perception and of existential affectation. Poetic speech goes beyond the limits of language, creating and establishing meanings and representations to the affectations that poetry provides. Thus, through poetry man recognizes himself in his worldliness, in search of his own being and in his relationship with other beings. (shrink)

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)

This paper shows that the semantics of shenme ‘what’ in Chinese bare conditionals may exhibit a phenomenon of double quantification. I argue that such double quantification can be nicely accounted for if one adopts Carlson's (1977a, b) semantics of bare plurals and verb meanings as well as the following two assumptions: (i) shenme ‘what’ can be a proform of bare NPs and hence has the same kind of denotation as bare NPs, and (ii) Chinese bare NPs are names of kinds (...) of things. This analysis of Chinese bare conditionals lends support to Carlson's approach to bare plurals despite Wilkinson's (1991) criticisms. I also show that an extension of Heim's (1987) analysis of what as ‘something of kind x’ to Chinese shenme ‘what’ encounters problems when shenme ‘what’ is a shared constituent of a predicate which applies to kinds and another predicate which applies to objects.

This paper is a critical examination of Wittgenstein's view of the limits of intelligibility. In it I criticize standard analytic readings of Wittgenstein as an advocate of transcendental or behaviourist theses in epistemology; and I propose an alternative interpretation of Wittgenstein's view as a social contextualism that transcends the false dichotomy between Kantianism and psychologism. I argue that this social contextualism is strikingly similar to the social account of epistemic practices developed by Pierre Bourdieu. Through a comparison between Wittgenstein's and (...) Bourdieu's view and an analysis of the notion of habitus, I try to show how social contextualism can account for the distinction between sense and nonsense without falling into transcendental constructivism or social behaviourism.

A substantial body of theoretical literature testifies to the evolutionary functions of emotions. Relatively little has been written about their developmental functions. This article discusses the developmental functions of emotions from the perspective of differential emotions theory (DET; Izard, 1977, 1991). According to DET, although all the emotions retain their adaptive and motivational functions across the lifespan, different sets of emotions may become relatively more prominent in the different stages of life as they serve stage-related developmental processes. In the first (...) section, we present a brief overview of relevant aspects of the theory. In the second section, we discuss how emotions play a central role in helping the individual achieve developmental milestones and tasks during four major periods of life: Infancy, toddler through preschool years, middle to late childhood, and adolescence. The underlying thesis of this article is that emotions play a central role in stimulating social cognitive attainments at each stage of development. (shrink)

I consider the problem of extending Reichenbach's principle of the common cause to more than two events, vis-a-vis an example posed by Bernstein. It is argued that the only reasonable extension of Reichenbach's principle stands in conflict with a recent proposal due to Horwich. I also discuss prospects of the principle of the common cause in the light of these and other difficulties known in the literature and argue that a more viable version of the principle is the one provided (...) by Penrose and Percival (1962).

The principle of maximum entropy is a general method to assign values to probability distributions on the basis of partial information. This principle, introduced by Jaynes in 1957, forms an extension of the classical principle of insufficient reason. It has been further generalized, both in mathematical formulation and in intended scope, into the principle of maximum relative entropy or of minimum information. It has been claimed that these principles are singled out as unique methods of statistical inference that agree with (...) certain compelling consistency requirements. This paper reviews these consistency arguments and the surrounding controversy. It is shown that the uniqueness proofs are flawed, or rest on unreasonably strong assumptions. A more general class of inference rules, maximizing the so-called Re[acute ]nyi entropies, is exhibited which also fulfill the reasonable part of the consistency assumptions. (shrink)

In this paper, we examine the relation between corporate social responsibility (CSR) and firm risk in controversial industry sectors. We develop and test two competing hypotheses of risk reduction and window dressing. Employing an extensive U.S. sample during the 1991-2010 period from controversial industry firms, such as alcohol, tobacco, gambling, and others, we find that CSR engagement inversely affects firm risk after controlling for various firm characteristics. To deal with endogeneity issue, we adopt a system equation approach and difference regressions (...) and continue to find that CSR engagement of firms in controversial industry sectors negatively affects firm risk. To examine the premise that firm risk is more of an issue for controversial firms, we further examine the difference between non-controversial and controversial firm samples, and find that the effect of risk reduction through CSR engagement is more economically and statistically significant in controversial industry firms than in non-controversial industry firms. These findings support the risk-reduction hypothesis, but not the window-dressing hypothesis, and the notion that the top management of U.S. firms in controversial industries is, in general, risk averse and that their CSR engagement helps their risk management efforts.

It has been a longstanding problem to show how the irreversible behaviour of macroscopic systems can be reconciled with the time-reversal invariance of these same systems when considered from a microscopic point of view. A result by Lanford shows that, under certain conditions, the famous Boltzmann equation, describing the irreversible behaviour of a dilute gas, can be obtained from the time-reversal invariant Hamiltonian equations of motion for the hard spheres model. Here, we examine how and in what sense Lanford’s theorem (...) succeeds in deriving this remarkable result. Many authors have expressed different views on the question which of the ingredients in Lanford’s theorem is responsible for the emergence of irreversibility. We claim that these interpretations miss the target. In fact, we argue that there is no time-asymmetric ingredient at all. (shrink)

Since the collapse of the Berlin wall, women and girls have been trafficked from central and eastern Europe to work as prostitutes in the European Union. This paper looks at the response of the international community to the problem of sex trafficking as it impacts on the EU. The focus is on criminal justice intervention with respect to protection of and assistance to ‘victims’, and a specially witness protection, in the light of the following: the tensions and promises between treatment (...) of trafficked women as ‘victims’ of crime and criminal justice informants; and the need to re-focus on a ‘woman-centred’ approach to criminal justice intervention for trafficked women. Given the diverse nature of law and criminal justice practice between EU Member States, the paper necessarily presents a generic critique of current EU and international ‘best practice’ recommendations, with some commentary on practice based on the author's research, with respect to what ‘gold standards’ of practice offer in theory and what is delivered in reality. The question of ‘victim-centred’ justice and/or ‘woman-centred’ justice is raised in an effort to promote effective policy recommendations. (shrink)
