In the early 1920s, Hans Reichenbach and Kurt Lewin presented two topological accounts of time that appear to be interrelated in more than one respect. Despite their different approaches, their underlying idea is that time order is derived from specific structural properties of the world. In both works, moreover, the notion of genidentity--i.e., identity through or over time--plays a crucial role. Although it is well known that Reichenbach borrowed this notion from Kurt Lewin, not much has been written about their (...) relationship, nor about the way Lewin implemented this notion in his own work in order to ground his topology. This paper examines these two early versions of the topology of time, and follows the extent of Lewin’s influence on Reichenbach’s proposal. (shrink)

Spatial representations have been considered for their high didactical efficacy, as concept maps and mind maps. Graphical and spatial representations may be seen as key elements of knowledge management and may contribute to enhancing spatial knowledge. Even if isomorphisms between the physical and the mental dimension can be controversial in the field of spatial knowledge, it is nevertheless interesting to study the role of spatial interpretation in knowledge management processes. In science education, spatial skills are actually highly required due to (...) the development of new technologies and their highly demanding spatial tasks they often work intertwined with other abilities, such as logical reasoning and verbal skills. Despite spatial knowledge being significative in the overall field of learning management, there is instead little research that shows its complex role in the comprehension of concepts in the humanistic fields, e.g. in philosophical conceptual reasoning. The Elementary Logic Theory—which underlies the philosophical maps of this Atlas—identifies at the basis of complex thinking prototypical knowledge units that may be activated in the possible collaboration between explicit and implicit thinking. In EL Theory, spatiality is considered the most suitable transition format for the hypothesized collaboration between implicit and explicit processing because it shares common aspects with both of them. The focus of EL Theory is to research particularly the role of the implicit in knowledge comprehension through spatial representations. In this Atlas, the role of Elementary Logic Theory is highlighted in shaping philosophical knowledge and comprehension of philosophical concepts and their intertwining. (shrink)

In this article the author maintains that complexity theory relies on reductionist assumptions, showing itself not to be completely convincing in dealing with the issue of novelty. First, an outline of Mark C. Taylor's The Moment of Complexity is presented as an exemplary case, particularly for his attempt to import complexity theory into the social sciences. Then, the connection between complexity theory and evolutionism is considered, arguing that this connection prevents complexity theory from giving a convincing account of the emergence (...) of novelty. A provisional conclusion is offered by arguing that novelty should be conceived as arising from a "widening" of reduction at the individual level. (shrink)

Synaptophysin (Syp) was the first synaptic vesicle (SV) protein to be cloned. Since its discovery in 1985, it has been used by us and by many laboratories around the world as an invaluable marker to study the distribution of synapses in the brain and to uncover the basic features of the life cycle of SVs. Although single gene ablation of Syp does not lead to an overt phenotype, a large body of experimental data both in vitro and in vivo indicate (...) that Syp (alone or in association with homologous proteins) is involved in multiple, important aspects of SV exo‐endocytosis, including regulation of SNARE assembly into the fusion core complex, formation of the fusion pore initiating neurotransmitter release, activation of SV endocytosis and SV biogenesis. In this article, we summarise the main results of the studies on Syp carried out by our and other laboratories, and explain why we believe that Syp plays a major role in SV trafficking.

In his Scientific Representation (2008), van Fraassen argues that measuring is a form of representation. In fact, every measurement pinpoints its target in accordance with specific operational rules within an already-constructed theoretical space, in which certain conceptual interconnections can be represented. Reichenbach’s 1920 account of coordination is particularly interesting in this connection. Even though recent reassessments of this account do not do full justice to some important elements lying behind it, they do have the merit of focusing on a different (...) aspect of his early work that traditional interpretations of relativized a priori principles have unfortunately neglected in favour of a more “structural” role for coordination. In Reichenbach’s early work, however, the idea of coordination was employed not only to indicate theory-specific fundamental principles such as the ones suggested in the literature on conventional principles in science, but also to refer to more “basic” assumptions. In Reichenbach, these principles are preconditions both of the individuation of physical magnitudes and of their measurement, and, as such, they are necessary to approach the world in the first instance. This paper aims to reassess Reichenbach’s approach to coordination and to the representation of physical quantities in light of recent literature on measurement and scientific representation.

A inquietação que caracteriza essa investigação é a suspeita de que o período do Renascimento, conhecido pelo florescimento da ciência, da arte e da cultura, pelos pensadores humanistas e por uma filosofia voltada ao tema da liberdade política, tenha se aberto pouco, ou quase nada, às mulheres. Na filosofia, se nos dirigimos ao debate político do período nos deparamos com um discurso que toma a ideia de igualdade como pressuposto para se pensar a liberdade política. De fato, as questões em (...) torno do tema do republicanismo versavam, em grande medida, sobre a maior ou menor participação popular. No entanto, esses âmbitos de debate não parecem passar pelo tema da inclusão das mulheres em nenhum âmbito do espaço público. As demandas femininas sequer podiam ser postas nos mesmos termos do debate característico do período. Assumindo como referencial teórico a historiadora do Renascimento Margaret king, pretende-se vislumbrar as questões próprias do período pela perspectiva das mulheres. Nesse sentido, o objetivo desse trabalho é investigar em que medida o período que reconhecemos na filosofia como Renascimento viabilizou (ou não) a inclusão de mulheres no espaço público e no debate filosófico. Procuraremos investigar essas questões a partir dos questionamentos filosóficos feitos por Christine de Pizan (1364-1430) em sua obra ‘A Cidade das Damas’, principalmente a partir da denúncia de uma voz unívoca contra as mulheres, perpassando o período do Renascimento até chegarmos aos escritos de Arcangela Tarabotti (1604-1652), e seu tratado intitulado ‘Tirania Paterna’.

El examen de carácter dialéctico que Aristóteles lleva a cabo del pensamiento de sus predecesores ha sido, como se sabe, blanco de duras críticas que cuestionan su honestidad intelectual y el valor de su indagación histórico-filosófica. Sin pretender ahondar en el tema de la naturaleza y funciones de la dialéctica aristotélica en sí misma, abordaré su tratamiento específicamente a la luz de la interpretación de Silvana Di Camillo, a modo de homenaje a su trayectoria. Sostendré, en acuerdo con la autora (...) y como resultado de un análisis propio de las fuentes correspondientes, que la investigación aristotélica de las filosofías de sus antecesores y, en especial, la de Platón, tiene como única y principal finalidad ‘la búsqueda de la verdad y el avance del conocimiento’ a través de una confrontación dialéctica que lo lleva a ofrecer respuestas alternativas a las dificultades que encuentra, edificando así un nuevo modelo explicativo de la realidad. Con tal fin, analizaré las críticas aristotélicas a los primeros pensadores en _Me_t_afísica_ I 3, las dirigidas a la teoría platónica de las Ideas, tanto en _Metafísica_ I 9 cuanto en _Sobre las Ideas_ y finalmente, la crítica a la Idea del Bien en _Ética Nicomaquea_ I 6. Sobre esta base, pondré de manifiesto cómo el estagirita privilegia ‘la verdad’ cuando, según él, en honor a ella, debe ir contra su maestro. Con todo, recordaré que es Platón antes que Aristóteles quien recalca la primacía de la verdad frente a la amistad al decir en _República_ X 595c, por ejemplo, que “no se debe honrar a un hombre más que a la verdad”. Por último, concluiré que es de la mano de Platón que Aristóteles avanza en su indagación manteniendo siempre encendida la antorcha de la verdad. (shrink)

Ethics in research became a central theme regarding globalization of the scientific development, particularly when related to the socioeconomic conditions of the countries involved as partners in research protocols, production of inputs and of knowledge. The objective of this paper is to analyze the sources of information about ethics in research present at Scientific Electronic Library Online. Methodologically, this is an exploratory study was carried out by the systematic analysis of the literature available. The search engines retrieved 885 summaries, from (...) which 170 were analyzed. The first publication was dated from 1996 and it could be identified the mention to international documents about research in humans. Since 2002 there has been an increase of publications related to the gain of legitimacy of the topic in academy. As a conclusion, although the amount is not huge, the manuscripts presented great impact as they stimulated debates and produced scientific knowledge on the topic. It can be observed that ethics in research has outcome the biomedical field, being inserted in other fields of knowledge. (shrink)

In recent years, Reichenbach's 1920 conception of the principles of coordination has attracted increased attention after Michael Friedman's attempt to revive Reichenbach's idea of a "relativized a priori". This paper follows the origin and development of this idea in the framework of Reichenbach's distinction between the axioms of coordination and the axioms of connection. It suggests a further differentiation among the coordinating axioms and accordingly proposes a different account of Reichenbach's "relativized a priori".

May implicit and explicit collaboration influence text comprehension and spatial recognition interaction? Visuospatial representation implies implicit, visual and spatial processing of actions and concepts at different levels of awareness. Implicit learning is linked to unaware, nonverbal and prototypical processing, especially in the early stages of development when it is prevailing. Spatial processing is studied as knowledge prototypes , conceptual and mind maps . According to the hypothesis that text comprehension and spatial recognition connecting processes may also be implicit, this paper (...) analyzes the possibility to identify and to define implicit non verbal criteria for organizing concepts into spatial representation. The focus of the research question is if prototypical processing (mainly implicit, but also explicit) criteria of conceptual organization may be model based. According to Thinking Prototypes Theory , explicit knowledge could be supported by implicit models of basic processing. On implicit side, conceptual development could be the resultant of the increasing complexity of prototypical implicit models interaction during individual lifespan, as in conceptual change research explicit conceptual development may be dependent on correlation . Unlike Theory Theory in Thinking Prototypes Theory implicit processing may collaborate with explicit knowledge without transforming itself from implicit to explicit. Prototypical implicit processing is considered as an entanglement of basic functions operating synergically in a complex way. Prototypical implicit processing units may be classified as far as they concern different basic thinking operations ( add , chain , each , compare , focus and link ). The experimental design was developed with primary school students in Naples. (shrink)

This highly multidisciplinary collection discusses an increasingly important topic among scholars in science and technology studies: objectivity in science. It features eleven essays on scientific objectivity from a variety of perspectives, including philosophy of science, history of science, and feminist philosophy. Topics addressed in the book include the nature and value of scientific objectivity, the history of objectivity, and objectivity in scientific journals and communities. Taken individually, the essays supply new methodological tools for theorizing what is valuable in the pursuit (...) of objective knowledge and for investigating its history. The essays offer many starting points, while suggesting new avenues of research. Taken collectively, the essays exemplify the very virtues of objectivity that they theorize—in reading them together, the reader can sense various anxieties about the dangerously subjective in our age and locate commonalities of concern as well as differences of approach. As a result, the volume offers an expansive vision of a research community seeking a communal understanding of its own methods and its own epistemic anxieties, struggling to enunciate the key problems of knowledge of our time and offer insight into how to overcome them. -/- (Contributors: Alex Csiszar, Scott Edgar, Peter Galison, Ian Hacking, Sandra Harding, Moira Howes, Paolo Savoia, Judy Segal, Joan Steigerwald, and Alison Wylie).

Es conocido el efecto de espectacularización derivado del proceso de colonialización-mundialización de la cultura: una vez que la actividad local ingresa en la economía política mundial de la cultura, cada acontecimiento se vuelve espectáculo , con su doble aspecto de “estrellato” y “museificación”. En efecto, ante la multiplicación de modos de vida que circulan en las redes telecomunicacionales, Estados e industrias culturales buscan por un lado preservar formas sociales y culturales que se consideran en peligro y, por otro, difundir y (...) explicar esas mismas formas. En este marco, el museo ha aparecido últimamente como uno de los dispositivos privilegiados para afrontar este doble propósito. Analizaré aquí un museo que se resiste a petrificar aquello que pretende cuidar, así como a extraer el núcleo de su razón de ser únicamente de las motivaciones económicas asociadas a la inversión en cultura. Me refiero al Museo-Taller Ferrowhite, ubicado en Ingeniero White, provincia de Buenos Aires. Propongo que se trata de un museo que se sabe un artefacto cultural hiper complejo, capaz de identificar la tensión que él mismo encarna, como institución estatal, al intentar contar la (su) historia y proponer un sentido para el rescate de esa historia en el presente.

Resenha do livro Filosofia da Ancestralidade de Eduardo David de Oliveira.

Kepler’s laws provided sufficient geometry and kinematics to strengthen astronomers’ preference for heliocentrism. While Kepler outlined some dynamic arguments, they were not rigorous enough to turn his laws into kinematic tools. As a result, some astronomers found ways to reconcile Kepler’s findings with geo-heliocentrism. One of these was the Jesuit astronomer Giovanni Battista Riccioli, who proposed a method known as the “epic-epicycle” (Riccioli, Almagestum novum, 1651). This paper will explore how Riccioli received and interpreted Kepler’s first and second laws within (...) his own astronomical framework. This analysis will include a discussion of how Riccioli understood the concept of “physics” in his work, beginning with a study of the Sun’s motion (Riccioli, Astronomia reformata, 1665). (shrink)

…sit necessaria sciencia mathematice ad bona anime procuranda.Scientific humanism in the 15th and 16th century witnessed the spread of Greek and Arabic mathematics, whose reading was disciplined by philological research, enriched by the practical sense of abacus masters and diffused by the press. This doesn't mean that before this time many of these works were totally unknown. Around the 13th century mathematics scholars were already familiar with the work of Theodosius, Archimedes, Vitruvius, the Banū Mūsā brothers and so on; however, (...) these works were confined to small intellectual circles, and turned into an object for philosophical speculation.This was the case of...

A pesquisa “Formação do leitor: o processo de mediação do docente” enfoca práticas mediadoras de leitura do texto literário, em ambiente escolar, nas séries iniciais do Ensino Fundamental. Inicialmente buscou-se investigar as práticas de leitura literária desenvolvidas em turmas de 3ª série e na biblioteca escolar de escolas localizadas em Caxias do Sul. As ações desenvolvidas são restritas e ante o quadro, o projeto organiza propostas de leitura literária a partir de diversos gêneros literários. O subprojeto “Leitura e mediação do (...) conto popular” focaliza o conto popular como gênero presente na formação do leitor literário, uma vez que a análise do corpus coletado aponta que há falhas na abordagem dessa narrativa. Provavelmente isso ocorre pela falta de clareza sobre as qualidades que conferem a uma obra o estatuto de literatura. Também se nota a predominância de concepções estruturalistas de leitura na prática docente, produzindo leituras autoritárias, que prevalecem sobre práticas mediadoras. Para estudar a natureza do conto popular, buscas e apoio em Jolles (1976), Jesualdo (1982), Cascudo (1998, 2002) e Azevedo (2008a, 2008b). A partir da análise do conto e dos dados coletados, constroem-se princípios e estratégias para a mediação de leitura do texto literário infantil, utilizando estudos de Saraiva (2001) e Saraiva e Mügge (2006). Esse referencial embasa a elaboração de roteiros de leitura para obras literárias infantis, entre elas A lenda do guaraná: mito dos índios sateré-maué, de Fittipaldi, objeto de estudo dessa proposta de trabalho. Acredita-se que a apresentação de propostas de leitura literária contribua para a formação continuada do docente, para qualificar a interação entre objeto de leitura e leitor iniciante. (shrink)

Augustine’s analysis of time in Book XI of Confessions represents for Ludwig Wittgenstein a good example of a philosophical question. In dealing with such theme, his thought undergoes relevant changes. In the Philosophical Remarks, written more than 10 years after the drafting of the Tractatus, the Austrian philosopher holds that the essence of the world can be expressed in the grammar of language. Philosophy as “custodian” of grammar can grasp the essence of the world by excluding nonsensical combinations of signs. (...) Philosopher, however, are often “tempted” to straightly describe the nature of the world, producing logical-grammatical paradoxes. An example of such a temptation is offered by the attempt to take hold of the essence of time using propositions like “only the present experience has reality.” The logical mistake hidden in this proposition lies in the bad use of the adjectival word “present” that would lose its everyday use and functional role in the language. Only comparing the term “present” with the background of other words referring to time experiences like “past,” “future,” and so on, we are able to understand the true sense of it. Engaging in a grammatical investigation into the notion of time helps us to dispel the different uses of it staving off logical muddles. Wittgenstein makes, in his lecture held at Cambridge in 1932–1933, a relevant distinction between what he calls “memory-time” and “information-time.” If the first can be understood as a now-centered system mostly expressed by indexical sentences or as an arrangement relied on memory, and therefore inadequate to give any external physical criteria for time measurements, the second clearly refers to a public chronology, implemented by clocks, calendars, diaries, and so on. Grammatical misconceptions, however occur when we are “tyrannized” by a metaphor and not able to “move outside of” it. The Austrian philosopher makes no secret of preferring a characterization of time that rejects a truth-functional interpretation. As for the notion of “game” in the Philosophical Investigations, it is impossible to have something like a common denominator shared by every sentence involving time. (shrink)

This paper reconstructs the concept of the «feeling» elaborated by William James in the text The Varieties of Religious Experience: a study in human nature as a mean towards a moral education. The analysis of the feeling expecially the religious one is structurally connected, in this writing of James, not only with thebiographical problem of the conscience and the knowledge of the self, but also with the strategically wider issue, of «a study of the human nature». The analysis of the (...) experience conducted from the pragmatist perspective allows us to specify the pedagogical function of the «spiritual feeling» in the path of consciousness of the subject: the faith, in fact, seen in its operative dynamic, increases the experimental conviction that the world can improve and it prepares in such way to raise and to invigorate the relationship with the life. In such perspective it is underlined the «therapeutic» function of moral emotions for the existence in general, and their specific impact on the process of formation and behavior of the human being.

The purpose of this scoping review is to investigate the value of creative arts therapies in healthy older adults. This article aims to shed light on current knowledge concerning the effectiveness of art therapies for the prevention of common age-related conditions using the definition of art therapy provided by the American Art Therapy Association, as well as Cohen’s conceptual framework for the psychological conceptualization of the relationship between the arts and health in later life. The objective is to carefully capture (...) subthreshold situations of distress, which are often not taken into account and primarily involve psychological aspects that are crucial in the multidimensional perspective of healthy aging. Twelve articles were selected and examined following an initial electronic search on 3 databases. A thematic analysis of the results identified four major themes: improving cognitive performance and proprioception; enhancing self-identity and meaningful life; reducing feelings of loneliness and depressive symptoms; and the importance of socialization. All these aspects constitute the basis for preventing psychological distress and enhancing mental well-being for healthy aging. (shrink)

Platelets have important hemostatic functions in repairing blood vessels upon tissue injury. Cytokines, growth factors, and metabolites stored in platelet α‐granules and dense granules are released upon platelet activation and clotting. Emerging evidence indicates that such platelet‐derived signaling factors are instrumental in guiding tissue regeneration. Here, we discuss the important roles of platelet‐secreted signaling factors in skeletal muscle regeneration. Chemokines secreted by platelets in the early phase after injury are needed to recruit neutrophils to injured muscles, and impeding this early (...) step of muscle regeneration exacerbates inflammation at later stages, compromises neo‐angiogenesis and the growth of newly formed myofibers, and reduces post‐injury muscle force production. Platelets also contribute to the recruitment of pro‐regenerative stromal cells from the adipose tissue, and the platelet releasate may also regulate the metabolism and proliferation of muscle satellite cells, which sustain myogenesis. Therefore, harnessing the signaling functions of platelets and the platelet secretome may provide new avenues for promoting skeletal muscle regeneration in health and disease. (shrink)

This paper presents an intuitive explanation about why and how Rawlsian Theory of Justice (Rawls in A theory of justice, Harvard University Press, Harvard, 1971) provides the foundations to a solution for algorithmic bias. The contribution of the paper is to discuss and show why Rawlsian ideas in their original form (e.g. the veil of ignorance, original position, and allowing inequalities that serve the worst-off) are relevant to operationalize fairness for algorithmic decision making. The paper also explains how this leads (...) to a specific MinMaxfairness solution, which addresses the basic challenges of algorithmic justice. We combine substantive elements of Rawlsian perspective with an intuitive explanation in order to provide accessible and practical insights. The goal is to propose and motivate why and how the MinMaxfairness solution derived from Rawlsian principles overcomes some of the current challenges for algorithmic bias and highlight the benefits provided when compared to other approaches. The paper presents and discusses the solution by building a bridge between the qualitative theoretical aspects and the quantitative technical approach. (shrink)
