Los niños con trastorno por déficit de atención con hiperactividad presentan alteraciones en el desarrollo de la función ejecutiva que se traducen en dificultades del control atencional y de la flexibilidad cognitiva. Considerando la complejidad de los procesos involucrados en la comprensión de lectura y el papel fundamental que en ellos cumple la función ejecutiva, puede esperarse que los niños con TDAH presenten diferencias en su desempeño lector en comparación con sus pares sin TDAH. El presente estudio, de carácter correlacional-predictivo, (...) tiene como propósito determinar si tales diferencias de comprensión lectora existen realmente y si es posible predecirlas a partir de la función ejecutiva. Para ello se seleccionaron 71 escolares de tercer y cuarto año de enseñanza básica y se les evaluó la habilidad de comprensión de lectura, el reconocimiento de palabras, la amplitud de la memoria de trabajo verbal, el control atencional y la velocidad de procesamiento. Con el fin de determinar qué variables tenían capacidad para predecir el nivel de comprensión de los escolares se aplicó un análisis de regresión logística binaria. Los resultados ponen en evidencia que el TDAH afecta significativamente el desempeño lector de los escolares y que las variables vinculadas a la función ejecutiva, especialmente la memoria de trabajo, son buenos predictores del rendimiento en comprensión de lectura.

Ontic Structural Realism is a version of realism about science according to which by positing the existence of structures, understood as basic components of reality, one can resolve central difficulties faced by standard versions of scientific realism. Structures are invoked to respond to two important challenges: one posed by the pessimist meta-induction and the other by the underdetermination of metaphysics by physics, which arises in non-relativistic quantum mechanics. We argue that difficulties in the proper understanding of what a structure is (...) undermines the realist component of the view. Given the difficulties, either realism should be dropped or additional metaphysical components not fully endorsed by science should be incorporated. (shrink)

This paper introduces the logic of evidence and truth \ as an extension of the Belnap–Dunn four-valued logic \. \ is a slightly modified version of the logic \, presented in Carnielli and Rodrigues. While \ is equipped only with a classicality operator \, \ is equipped with a non-classicality operator \ as well, dual to \. Both \ and \ are logics of formal inconsistency and undeterminedness in which the operator \ recovers classical logic for propositions in its scope. (...) Evidence is a notion weaker than truth in the sense that there may be evidence for a proposition \ even if \ is not true. As well as \, \ is able to express preservation of evidence and preservation of truth. The primary aim of this paper is to propose a probabilistic semantics for \ where statements \\) and \\) express, respectively, the amount of evidence available for \ and the degree to which the evidence for \ is expected to behave classically—or non-classically for \ \). A probabilistic scenario is paracomplete when \ + P 1\), and in both cases, \ < 1\). If \ = 1\), or \ = 0\), classical probability is recovered for \. The proposition \, a theorem of \, partitions what we call the information space, and thus allows us to obtain some new versions of known results of standard probability theory. (shrink)

In this paper, 1 examine the role of the delta function in Dirac’s formulation of quantum mechanics (QM), and I discuss, more generally, the role of mathematics in theory construction. It has been argued that mathematical theories play an indispensable role in physics, particularly in QM [Colyvan, M. (2001). The inrlispensability of mathematics. Oxford University Press: Oxford]. As I argue here, at least in the case of the delta function, Dirac was very clear about its rlispensability. I first discuss the (...) significance of the delta function in Dirac’s work, and explore the strategy that he devised to overcome its use. l then argue that even if mathematical theories turned out to be indispensable, this wouidn’t justify the commitment to the existence of mathematical entities. In fact, even in successful uses of mathematics, such as in Dirac’s discovery of antimatter, there’s no need to believe in the existence of the corresponding mathematical entities. An interesting picture about the application of mathematics emerges from a careful examination of Dirac’s work. (shrink)

Amie Thomasson has articulated a novel conception of ontological debates, defending an easy approach to ontological questions as part of the articulation of a deflationary metaphysical view (Thomasson, 2015). After raising some concerns to the approach, we sketch a neutralist alternative to her ontological framework, offering an even easier way of conducting ontological debates.

Although remote working can involve positive outcomes both for employees and organizations, in the case of the sudden and forced remote working situation that came into place during the COVID-19 crisis there have also been reports of negative aspects, one of which is technostress. In this context of crisis, leadership is crucial in sustainably managing and supporting employees, especially employees with workaholic tendencies who are more prone to developing negative work and health outcomes. However, while research on the role of (...) the positive aspects of leadership during crises does exist, the negative aspects of leadership during the COVID-19 crisis have not yet been studied. The present study aimed to explore the role of authoritarian leadership in a sample of 339 administrative university employees who worked either completely from home or from home and the workplace. The study examined the moderating effect of a manager on this relationship and the connections between workaholism and technostress through conditional process analysis. Results pointed out that high authoritarian leadership had an enhancing effect, whereas low authoritarian leadership had a protective effect on the relationship between workaholism and technostress, only in the group of complete remote workers. Thus, authoritarian leadership should be avoided and training leaders to be aware of its effect appears to be essential. Limitations, future directions for the study, and practical implications are also discussed. (shrink)

The aim of this paper is to provide a unified account of scientific and mathematical change in a thoroughly empiricist setting. After providing a formal modelling in terms of embedding, and criticising it for being too restrictive, a second modelling is advanced. It generalises the first, providing a more open-ended pattern of theory development, and is articulated in terms of da Costa and French's partial structures approach. The crucial component of scientific and mathematical change is spelled out in terms of (...) partial embeddings. Finally, an application of this second pattern is made, with the examination of the early formulation of set theory. (shrink)

Consider the following denumerably infinite sequence of sentences: (s1) For all k > 1, sk is not true. (s2) For all k > 2, sk is not true. (s3) For all k > 3, sk is not true.

In this paper, I provide an easy road to nominalism which does not rely on a Field-type nominalization strategy for mathematics. According to this proposal, applications of mathematics to science, and alleged mathematical explanations of physical phenomena, only emerge when suitable physical interpretations of the mathematical formalism are advanced. And since these interpretations are rarely distinguished from the mathematical formalism, the impression arises that mathematical explanations derive from the mathematical formalism alone. I correct this misimpression by pointing out, in the (...) cases recently discussed by Mark Colyvan, exactly where the interpretations of the formalism were invoked and the function they played in the resulting explanations. A viable form of easy - road nominalism, which is also sensitive to scientific practice, then arises. (shrink)

In this paper, I offer an inferential conception of computer simulations, emphasizing the role that simulations play as inferential devices to represent empirical phenomena. Three steps are involved in a simulation: an immersion step, a derivation step, and an interpretation and correction step. After presenting the view, I mention some cases, such as simulations of the current flow between silicon atoms and buckyballs as well as of genetic regulatory systems. I argue that the inferential conception accommodates the integration of empirical (...) and theoretical data; it makes sense of the role that is played by false traits in a simulation, andhighlights the similarities and differences between simulations and scientific instruments.

Despite the alleged roles played by structures, substances, and facts in mathematical and metaphysical theorizing, in this paper I provide a strategy to dispense with them. It is argued that one need not be committed to the existence of these posits nor with the metaphysically inflationary interpretations that support them. An alternative, deflationary approach is then sketched.

This article shows the close relationship that exists between two fundamental concepts in the theological doctrine of Origen of Alexandria: “fullness” and“participation”. These two concepts have been the subject of many earlier studies. However, they treated the topic in a more restricted sense, exploring very specific aspects of Origenian theology. The originality of this study lies in demonstrating how both concepts recur frequently in his theological thinking, give it a framework and hold his thought together. They consequently systematize and make (...) possible a perfect synthesis of all his thinking. (shrink)

Objetiva-se, com o presente trabalho, uma efetiva contribuição às pesquisas interdisciplinares nas áreas de epistemologia social, direito, filosofia, economia e teoria política, que, em nossos dias atuais de incertezas e de cenários cada vez mais complexos, demandam dos agentes e legisladores justificações precisas de seus processos decisórios para implementar políticas públicas e ações coletivas que promovam efetivamente o bem comum em nossas democracias. Trata-se, em última análise, de uma aposta pragmática na busca por uma solução que melhor se adeque à (...) nossa realidade social em face da crise de representatividade e da falência aparente dos atuais mecanismos de eleição nas sociedades democráticas contemporâneas. Para tanto, é mister que se avalie atentamente as condições de racionalidade estabelecidas, considerando os requisitos formais de desempenho lógico, tais como foram historicamente desenvolvidos na teoria da escolha coletiva, visando uma resposta viável que não apenas represente um somatório de escolhas individuais, mas possa de fato traduzir uma verdadeira escolha social.

Apresentam-se aqui as conclusões de uma pesquisa em que foram analisados dois programas de televisão, um encarte de jornal e uma revista - todos destinados ao público adolescente. A análise, feita a partir de um referencial teórico baseado nos conceitos de sujeito, poder e discurso, da obra de Michel Foucault, permite qualificar a mídia como um "espaço formador de sujeitos'', basicamente porque seus discursos e as práticas que instauram constituem um modo especifico de "ser jovem" e se inscrevem numa rede (...) de poder e saber sobre a adolescência, possível de apreender a partir dos próprios textos.

Este artigo apresenta a relação existente entre a proposta de quatro escolas noturnas, criadas para crianças que trabalhavam nos serviços de capina nas ruas de Porto Alegre, e o processo mais amplo, de construção de futuros cidadãos, a partir da perspectiva positivista. A categoria analítica 'formação' permite explicar esse processo numa perspectiva relacionada à urbanização e industrialização, que estavam transformando a 'vida urbana' da cidade de Porto Alegre no primeiro quarto deste século. Dados retirados dos Relatórios da Intendência Municipal serviram (...) de base para a explicitação de como efetivamente este processo de formação se desenvolveu. (shrink)

In order to develop an account of scientific rationality, two problems need to be addressed: (i) how to make sense of episodes of theory change in science where the lack of a cumulative development is found, and (ii) how to accommodate cases of scientific change where lack of consistency is involved. In this paper, we sketch a model of scientific rationality that accommodates both problems. We first provide a framework within which it is possible to make sense of scientific revolutions, (...) but which still preserves some (partial) relations between old and new theories. The existence of these relations help to explain why the break between different theories is never too radical as to make it impossible for one to interpret the process in perfectly rational terms. We then defend the view that if scientific theories are taken to be quasi-true, and if the underlying logic is paraconsistent, it’s perfectly rational for scientists and mathematicians to entertain inconsistent theories without triviality. As a result, as opposed to what is demanded by traditional approaches to rationality, it’s not irrational to entertain inconsistent theories. Finally, we conclude the paper by arguing that the view advanced here provides a new way of thinking about the foundations of science. In particular, it extends in important respects both coherentist and foundationalist approaches to knowledge, without the troubles that plague traditional views of scientific rationality. (shrink)

This paper discusses logical accounts of the notions of consistency and negation, and in particular explores some potential means of defining consistency and negation when expressed in modal terms. Although this can be done with interesting consequences when starting from classical normal modal logics, some intriguing cases arise when starting from paraconsistent modalities and negations, as in the hierarchy of the so-called cathodic modal paraconsistent systems (cf. Bueno-Soler, Log Univers 4(1):137–160, 2010). The paper also takes some first steps in (...) exploring the philosophical significance of such logical tools, comparing the notions of consistency and negation modally defined with the primitive notions of consistency and negation in the family of Logics of Formal Inconsistency (LFIs), suggesting some experiments on their expressive power.

This chapter introduces a structural account of representation through partial structures and examines its ontological commitments. It is pointed out that structural approaches to scientific representation emphasize the crucial role played by structures in representing salient features of the world. It is common to present and, in some cases, even to reify such structures as abstract entities, in particular as set-theoretic constructs. Against this view, it is argued that no such reification is called for and that several strategies can be (...) articulated to avoid commitment to set-theoretic structures in the defense of structural representation. In the end, one can favor the latter without being platonist about the former. (shrink)

Neste artigo analisamos uma experiência, no campo da assistência social, desenvolvida na última década em Porto Alegre, a partir da contribuição da categoria formação. Enfatizamos a importância das atividades geradoras de renda por mulheres papeleiras junto aos galpões de reciclagem. A compreensão dessa prática social também envolve um processo formativo que incide também nos agentes de mediação bem como no conjunto da população.

Teresa of Avila's desire for suffering cannot be interpreted as the mere passive assumption of a feminine sacrificial role. On the contrary, Teresa was able to transform her suffering into the incarnated performance of her relationship with God: By desiring suffering and by understanding it and her ability to confront it as proof of divine love, she was able to reinforce her self‐confidence and strength. This article discusses Teresa of Avila's experience and interpretation of suffering in the context of the (...) female ascetic‐mystic Christian tradition. It criticizes Teresa's positive conceptualization of suffering but examines in depth the potential of her ability to actively manage and control it. Although Teresa was able to affirm her personality through ascetic practices such as self‐humiliation and mortification, the general applicability of such practices to the management of suffering is fraught since they leave the suffering individual in a vulnerable position. Although Teresa of Avila finds fulfillment and, paradoxically, self‐actualization through self‐denial and the surrender of her will, such practices entail the substantial risk of total self‐annihilation.

The article presents a set of articles on the present and projection of the scholastic tradition. The starting point is the anthropological turn that, within scholasticism and at the beginning of the fourteenth century, privileged the study of ethics, law and politics and, consequently, the forced development of a moral theology concerned with the human coexistence. The second scholasticism, prolonging this tradition throughout the 16th and 17th centuries, could not remain oblivious to the implications of the profound changes that were (...) taking place: the Discovery of America, the Protestant Reformation, the development of a commercial proto-capitalism and the strengthening of the monarchies. As the Reformation was consolidated in a good part of the European territories, intellectual borders were raised between the various confessions. However - and this is the focus of the papers presented - these borders were porous and, despite the climate of confrontation, various indirect communication channels managed to maintain a single intellectual republic.
