In recent years, digital tools, such as WhatsApp, have been increasingly deployed to support group interaction and collaboration in higher education contexts. To understand contemporary, digitally-mediated collaborative dynamics – including the role played by tutors and the situated nature of group development – robust and innovative methodologies are needed. In this paper, we illustrate how integrating qualitative methods with quantitative tools used in qualitative ways makes it possible to trace how tutors adapt their style to support group development, which in (...) turn triggers student development in a circular and responsive process. To make visible this contemporary phenomenon, we combine thematic content analysis – a qualitative tool – with a quantitative method: Social Network Analysis. Drawing on data generated by two WhatsApp learning groups in research exploring the collaborative construction of boundary objects in a master’s level “E-learning Psychology” course, we suggest that our methodological approach has the potential to support interrogation of complex and dynamic digitally-mediated group interactions. Our results show the situational nature of an effective tutorship style through its complex adaptation to learners’ maturity, digital tools, and learning goals. (shrink)

Texto do professor Antônio Cândido a respeito da atividade filosófica.

We investigated the contributions of familiarity of setting, self-relevance and self-projection in time to episodic future thinking. The role of familiarity of setting was assessed, in Experiment 1, by comparing episodic future thoughts to autobiographical future events supposed to occur in unfamiliar settings. The role of self-relevance was assessed, in Experiment 2, by comparing episodic future thoughts to future events involving familiar others. The role of self-projection in time was assessed, in both Experiments, by comparing episodic future thoughts to autobiographical (...) events that were not temporal in nature. Results indicated that episodic future thoughts were more clearly represented than autobiographical future events occurring in unfamiliar setting and future events involving familiar others. Our results also revealed that episodic future thoughts were indistinguishable from autobiographical atemporal events with respect to both subjective and objective detail ratings. These results suggest that future and atemporal events are mentally represented in a similar way. (shrink)

Vito Tanzi offers a truly comprehensive treatment of the economic role of the state in the twentieth and twenty-first centuries from a historical and world perspective. The book addresses the fundamental question of what governments should do, or have attempted to do, in economic activities in past and recent periods. It also speculates on what they are likely or may be forced to do in future years. The investigation assembles a large set of statistical information that should prove useful (...) to policy-makers and scholars in the perennial discussion of government's optimal economic roles. It will become an essential reference work on the analytical borders between the market and the state, and on what a reasonable 'exit strategy' from the current fiscal crises should be. (shrink)

The development of the various themes of Catholic Social Teaching is based on numerous papal documents and ecclesiastical statements. While this paper provides a summary of a number of these documents, this paper focuses on two themes: the common good and care of the environment, and on three documents authored by Pope John Paul II in 1990, by Pope Benedict XVI in 2010, and by Pope Francis in 2015. By analyzing these documents from an engineer’s perspective, the author proposes a (...) model for Socially Responsible Engineering. The proposed model is intended to serve as a guide for engineering students and practicing engineers of all faith traditions and to those with no faith tradition at all who wish to incorporate CST in the daily conduct of their personal and professional lives; to provide guidance for the professional the author terms the aspiring Socially Responsible Engineer; and to offer engineers a preferred alternative to the undesirable aspects of the technocratic paradigm. While intended primarily for engineers, this document also serves as a guide for those with expertise in social justice and who, by gaining a better understanding of the thought processes of engineers, can become better mentors for engineering students and practicing engineers seeking to incorporate CST into their daily lives.

Este artigo apresenta um pouco dos estudos de Roger Bacon sobre Alquimia. Filósofo medieval, Bacon deu sequência à tradição de estudos herméticos. Como parte de uma das ciências especiais, assim como ele a compreendia, a Alquimia teve destaque como elemento importante no seu projeto filosófico-científico. A fim de apresentar um pouco o lugar da Alquimia no corpus baconiano, o texto parte de uma breve exposição da possível origem dessa arte entre os povos da antiguidade oriental e, posteriormente, sua chegada à (...) Europa medieval. Passa-se então a apresentar os ensinamentos alquímicos transmitidos por Bacon; sua compreensão de Alquimia não como magia, mas como ciência positiva, cujos métodos e resultados podiam ser corroborados pela Ciência Experimental; a elaboração de uma breve chave de leitura dos termos alquímicos enviados ao Papa Clemente IV, juntamente com a defesa de que a Alquimia é uma arte hermética e precisa ser preservada da ignorância do homem comum, sendo revelada a quem a mereça em corpo e alma.

This memoir consists of two parts, of which the first deals with the foundations of the theory of the struggle for existence, and begins with the introduction of the important concept of quantity of life, besides that of population. The fundamental equations are then established for the case where the individuals of a biological association mutually devour each other, the reasoning being based on the principle of encounters and on the fundamental hypothesis of the existence of equivalents of the individuals (...) constituting the different species which form the association.Having now obtained the equations which determine the rates of change of the numbers of individuals and of the quantities of life of the species, the memoir proceeds to find the equations relating to the stationary state, by establishing theorems which are afterwards applied for the purpose of obtaining the three general laws of the fluctuations. This investigation of the equilibrium state is then followed by the determination of the integrals of the fluctuation equations, and the deduction from these of their most important consequences.The second part of the memoir contains the enumeration and demonstration of the general laws of the struggle for existence, which flow from the discussion of the principles and the integrals obtained in the first part. In this way there is established a new sort of dynamics, demographic dynamics, which, though substantially different from the dynamics of material systems, is developed from an analogous point of view.The second part begins with the principle of the conservation of demographic energy, according to which there are two sorts of energy, one actual and one potential, which transform mutually the one into the other. This principle is the analogue of the principle of conservation of mechanical energy. It is followed by the enunciation of the three laws relating to the biological fluctuations, the experimental verification of which has been investigated by several naturalists. The success which has attended their efforts is well known.Everybody knows the importance ofHamilton's principle in mechanics and in all the domains of physical science. An analogous variation principle can be found in biology, and from it one can deduce the fluctuation equations in the canonical Hamiltonian form and also in the form of a Jacobian partial differential equation. Their integrals in involution from the subject next studied, and in this way are found cases where the integration is reducible to quadratures.Hamilton's principle leads to the principle of least action . There exists also in biology a closely related principle, which may be called the principle of least vital action. Its analytical form is such that it requires the existence of a true minimum, a state of affairs which does not always hold good in the analogous case in mechanics.Die Abhandlung besteht aus zwei Teilen: Der erste ist den Grundlagen der Theorie des Kampfes ums Dasein gewidmet. Man beginnt damit, neben der Bevölkerung die Menge des Lebens einzuführen, welche eine sehr wichtige Rolle spielt. Man geht dann dazu über, die Grundgleichungen für den Fall aufzustellen, in welchem die Individuen einer biologischen Assoziation sich gegenseitig auffressen. Man wendet das Prinzip der Begegnungen an und stützt sich auf die Grundhypothese der Existenz von Individuenäquivalenten der verschiedenen Arten, welche die Assoziation bilden.Wenn man die Gleichungen, welche die Variationen der Individuenzahlen und der Lebensmengen der Arten liefern, gefunden hat, so schreitet man zu den statischen oder Gleichgewichtsgleichungen fort und findet so die Theoreme, die man alsdann benutzt, um die drei allgemeinen Gesetze der Fluktuationen zu erhalten.Nach dem Studium des Gleichgewichtes geht man dazu über, die verschiedenen Integrale der Fluktuationengleichungen zu finden und zieht endlich aus ihnen die wichtigsten Folgerungen.Im zweiten Teile werden die allgemeinen Gesetze des Kampfes ums Dasein, welche aus der Diskussion der Prinzipien und der im ersten Teil gewonnenen Integrale stammen, ausgesprochen und bewiesen. Man baut so eine neue Dynamik auf: die demographische Dynamik, welche, obschon sie wesentlich verschieden von derjenigen der materiellen Systeme ist, sich nach einem analogen Gesichtspunkt entwickelt.Man beginnt in diesem zweiten Teil mit dem Prinzip der Erhaltung der demographischen Energie, nach welchem zwei Energien, die aktuelle und die potentielle, sich ineinander verwandeln. Wir haben hier eine Analogie zum Prinzip der Erhaltung der mechanischen Energie. Dann werden die drei Gesetze der biologischen Fluktuationen formuliert. Für sie haben verschiedene Naturforscher experimentelle Bestätigungen gesucht. Man kennt den Erfolg ihrer Bemühungen.Alle Welt kennt die Bedeutung des Prinzips vonHamilton in der Mechanik und in allen Gebieten der Physik. Man kann ein dem Variationskalkül analoges Prinzip in der Biologie finden. Aus ihm kann man die Fluktuationsgleichungen in der kanonischen Form vonHamilton und in der Gestalt einer Gleichung mit partiellen Differentialquotienten vonJacobi herleiten. Ihre Integrale bilden den Gegenstand der folgenden Studien. Man findet Fälle, in denen die Integration sich auf Quadraturen reduziert.Das Prinzip vonHamilton zieht das Prinzip der kleinsten Wirkung oder das Prinzip vonMaupertuis nach sich. Auch in der Biologie gibt es ein mit dem vorgenannten zusammenhängendes Prinzip, welches man das Prinzip der kleinsten vitalen Wirkung nennen kann. Seine analytische Form ist derart, dass es sich um ein wahres Minimum handelt, das im analogen Fall in der Mechanik nicht immer zutrifft. (shrink)

Resumo O propósito deste texto é mostrar que os problemas enfrentados por Merleau-Ponty, ao longo de seu percurso de pensamento, decorrem dos pressupostos dicotômicos dos quais ele parte. Assim, procuramos trazer à tona outras consequências de se assumir tal pressuposto, o do primado de uma experiência perceptiva muda como solo natal de todas as outras modalidades da experiência. Para tanto, tomam-se em consideração tanto a primeira como a segunda fase do pensamento de Merleau-Ponty.Our purpose is to show that the problems (...) faced by Merleau-Ponty throughout his path of thought arise from the dichotomous assumptions from which he begins. Thus, we seek to shed light on the other consequences of assuming a presumption such as the primacy of a mute perceptual experience as the native soil of all other experience’s modes. Therefore, the first as well as the second phases of Merleau-Ponty’s thought are taken into account. (shrink)

Considerando retrospectivamente os desdobramentos da filosofia, é possível observar que, antes de reconhecer e reafirmar as singularidades de seu exercício, o discurso filosófico tem sua origem intimamente associada à poesia. Evidenciando alguns momentos de cisão e outros momentos de contato entre o discurso poético e o discurso filosófico, o presente ensaio visa abordar e refletir sobre o diálogo entre esses dois discursos ao longo do tempo. Nesse horizonte, consideraremos estrategicamente os trabalhos de autores como Homero, Platão, Goethe, F. Schlegel e (...) Schelling, a fim de evidenciar as oscilações e salientar alguns movimentos específicos dentro desse longo diálogo. (shrink)

Resumo: Palavras-chave : Learning mathematics in school is being faced with a world of concepts that involves reading and understanding of the natural language and mathematical language. Often, the curriculum components, Portuguese language and the Mathematic don’t talk to each other. The resolution of the problems seems to be a critical point in mathematics education. This article seeks to bring these components together to identify strategies for an effective learning. Keywords : Mathematical language.Natural language. Problems. : Linguagem matemática. Linguagem natural. (...) Problemas. Aprender Matemática na escola é deparar-se com um mundo de conceitos que envolvem leitura e compreensão, tanto da linguagem natural como da linguagem matemática. Muitas vezes, os componentes curriculares, a Língua Portuguesa e a Matemática não dialogam. A resolução de problemas parece ser um dos pontos críticos na Matemática escolar. Este artigo aproxima esses componentes de forma a buscar estratégias para uma aprendizagem efetiva. (shrink)

The early modern and modern cultural world in the West would be unthinkable without Petrarch and Boccaccio. Despite this fact, there is still no scholarly contribution entirely devoted to analysing their intellectual revolution. Internationally renowned scholars are invited to discuss and rethink the historical, intellectual, and literary roles of Petrarch and Boccaccio between the great model of Dante’s encyclopedia and the ideas of a double or multifaceted culture in the era of Italian Renaissance Humanism. In his lyrical poems and Latin (...) treatises, Petrarch created a cultural pattern that was both Christian and Classical, exercising immense influence on the Western World in the centuries to come. Boccaccio translated this pattern into his own vernacular narratives and erudite works, ultimately claiming as his own achievement the reconstructed unity of the Ancient Greek and Latin world in his contemporary age. The volume reconsiders Petrarch’s and Boccaccio’s heritages from different perspectives, and investigates how these heritages shaped the cultural transition between the end of the Middle Ages and the early modern era, as well as European identity.

Pode o criacionismo conceber-se como "ontologia de noções", dado o estatuto da noção (núcleo de relações construtoras do real) e o conceito de ser como pensamento e actividade criadora do pensamento, pondo a unidade da razação teórica e da prática. Esta última exigência encontra-se já em Antero de Quental pela ideia do númenp como fundamento teórico-prático do pensar, do sentir e do agir.Na coexistência anteriana duma razão eleática com uma dinâmica, viu Leonardo, na segunda, uma antecipação do pensamento como acção. (...) O valor pré-criacionista de Antero ainda no seu personalismo (embora abstracto em face do leonardino, que envolve uma doutrina do amor) e na teoria do divino, entrevendo-se Deus quase criacionistamente colocado na continuidade da vida moral. /// Le créationnisme peut se concevoir comme "ontologie de notions" vu le statut de la notion (noeud de relations constructices du réel) ainsi que le concept d'être comme pensée et activité créatrice de la pensée, posant l'unité de la raison théorique et pratique. Cette dernière exigence se trouve déjà chez Ante-ro de Quental par le biais de l'idée de noumène compris comme fondement théorico-pratique du penser, du sentir et de l'agir.Quant à la coexistence d'une raison éléatique avec une raison dynamique, Léonard a vu en celle-ci une anticipation de la pensée comme action. La dimension pré-créationniste de Antero réside également dans son personnalis-me (quoique abstrait face à celui de Léonard qui contient une doctrine de l'amour) et dans la théorie du divin, théorie qui suggère qui Dieu se situe de façon quasi créationniste dans le prolongement de la vie morale. /// It is possible to conceive "criationisme" as an "ontology of notions", given the status of notion (nucleus of relations which constitute the real) and the concept of being (thought and creative activity, uniting theoretical and practical reasons). The later theme is present in the work of Antero de Quen-tal in his conception of noumeno, considered as theoretical and practical foundation of thinking, feeling and acting.Leonardo recognized in the co-existence of Eleatic reason and of dynamic reality an anticipation of his idea of thought as action. The pre-criationist value of Antero resides in his personalism (although abstract in regards of the divine, where one can perceive God in a criationist mode and as placed in the continuity of moral life.

This article presents for the first time in english lesniewski's analysis of russell's antinomy as the analysis is given in lesniewski's 1914 paper "czy klasa klas, nie podporzadkowanych sobie, jest podporzadkowana sobie?" is the class of classes which are not subordinate to themselves subordinate to itself? it is shown how the concepts appearing in this paper, written in colloquial polish, were later incorporated and expressed as fundamental axioms and theorems of his theory of collective classes, mereology. in the 1914 paper (...) he asserted: i call any object p an object subordinate to a class k if in some sense of the expression "a" the following two conditions hold: 1) k is a class (of objects) "a", 2) p is an "a". using this explication of "p is subordinate to a class k," he showed that both of the following statements are false: a) the class of classes which are not subordinate to themselves is subordinate to itself, b) the class of classes which are not subordinate to themselves is not subordinate to itself; thus showing that russell's antinomy cannot be generated since its initial assumptions are false.

In [6] I tried to show how an objection to “the nominalist's” analysis of “This is red” and “That is red” on the basis of “the doctrine of common names” might be overcome. The objection is that “the nominalist,” attempting to analyze and by construing the pronouns in these sentences as two different proper names and “red” as a common name, is forced thereby to construe the copula in both sentences as the “is” of identity, and hence this and that (...) are identical, i.e., that there is only one red spot and not two. I attempted to show that by using Leśniewski's original axiom of ontology “the nominalist” could construe the pronouns in and as proper names, and “red” as a common name without taking the copula to express identity; he would not be forced to identify this with that.

2Public space is an old habit. The words public space are deceptive; when I hear the words, when I say the words, I’m forced to have an image of a physical place I can point to and be in. I should be thinking only of a condition; but, instead, I imagine an architectural type, and I think of a piazza, or a town square, or a city commons. Public space, I assume, without thinking about it, is a place where the (...) public gathers. The public gathers in two kinds of spaces. The first is a space that is public, a place where the public gathers because it has a right to the place; the second is a space that is made public, a place where the public gathers precisely because it doesn’t have the right—a place made public by force.3In the space that is public, the public whose space this is has agreed to be a public; these are people “in the form of the city,” they are public when they act “in the name of the city.” They “own” the city only in quotes. The establishment of certain space in the city as “public” is a reminder, a warning, that the rest of the city isn’t public. New York doesn’t belong to us, and neither does Paris, and neither does Des Moines. Setting up a public space means setting aside a public space. Public space is a place in the middle of the city but isolated from the city. Public space is the piazza, an open space separated from the closure of alleys and dead ends; public space is the piazza, a space in the light, away from the plots and conspiracies in dark smokey rooms. Vit Acconci’s latest show, entitled “Public Places,” was held in 1988 at the Museum of Modern Art, New York. He is currently at work on a park in Detroit, a pedestrian mall in Baltimore, and a housing project in Regensburg, Germany. (shrink)
