In human groups performing oscillatory tasks, it has been observed that the frequency of participants' oscillations reduces when compared to that acquired in solo. This experimental observation is not captured by the standard Kuramoto oscillators, often employed to model human synchronization. In this work, we aim at capturing this observed phenomenon by proposing three alternative modifications of the standard Kuramoto model that are based on three different biologically-relevant hypotheses underlying group synchronization. The three models are tuned, validated and compared against (...) experiments on a group synchronization task, which is a multi-agent extension of the so-called mirror game. (shrink)

This article represents the genre of auto-ethnographic, autobiographical research. It consists of questions which evoke narrative responses because the questions register a life story in itself. Pieter G.R. de Villiers is the interpellator and Andries G. van Aarde the respondent. They are long-standing friends and both professors of New Testament studies. De Villiers is presently the editor at LitNet Academic (Religious Studies), and Van Aarde is the editor of HTS Theological Studies. Since 1990, De Villiers has been Executive Director of (...) the Centre for Christian Spirituality and Ethics and has been a Research Fellow and Professor Extraordinarius in Biblical Spirituality at the Department of Old and New Testament Studies at the Faculty of Theology, University of the Free State (since 2001).Contribution: The article reflects a conversation between Andries G. van Aarde and Pieter G.R. de Villiers. It contributes to an understanding of contemporary South African church history, including the protest by academics in Afrikaans ecclesial circles against apartheid and gender injustice. (shrink)

Using a recent result of Busch and Gudder, we reconsider a theorem of Ludwig which allows one to identify a class of effect automorphisms as the symmetry transformations in quantum mechanics.

Como casi todos los conceptos fi losófi cos, el de «validez normativa» tiene altos grados de ambigüedad y de vaguedad. En este trabajo me encargo de analizar la postura de distintos autores que han tratado de dar respuesta a la pregunta ¿qué significa que una norma sea «válida»? Para ello, tomo como hilo conductor la obra de Ernesto Garzón Valdés. Esto se debe a que los trabajos de Ernesto Garzón dedicados a este tema, le ofrecen al lector un análisis crítico (...) y comprensivo de algunas de las posturas teóricas más relevantes sobre el concepto de validez normativa. Asimismo, trabajar a través de su obra tiene un doble benefi cio: por un lado, no sólo nos permite conocer a fondo la postura teórica de autores que pertenecen a distintas corrientes del pensamiento, como Hans Kelsen, H.L.A. Hart, Francisco Suárez o von Wright por ejemplo, sino que, por el otro, nos permite conocer la postura del mismo Garzón y sus críticas a los diferentes modelos conceptuales. (shrink)

The tree-based data structure of -tree for propositional formulas is introduced in an improved and optimised form. The -trees allow a compact representation for negation normal forms as well as for a number of reduction strategies in order to consider only those occurrences of literals which are relevant for the satisfiability of the input formula. These reduction strategies are divided into two subsets (meaning- and satisfiability-preserving transformations) and can be used to decrease the size of a negation normal form A (...) at (at most) quadratic cost. The reduction strategies are aimed at decreasing the number of required branchings and, therefore, these strategies allow to limit the size of the search space for the SAT problem. (shrink)

Este artigo pretende discutir os conceitos de direito natural e propriedade no Iuri universi distributio (1578) e as suas conseqüências políticas no Methodus ad facilem historiarum cognitionem (1566) e no Les Six Livres de la République (1576), de Jean Bodin.

In recent years, in the era of multiple crises, there are many political parties and leaders that use conspiracy theories in their discourse, trying to explain facts and figures on politics, economy, society, environment and space. There is an ongoing debate in populism studies on the possible connection between the populist phenomenon and conspiracy theories, thus creating two main theoretical camps. On the one hand, there are many scholars who recognize a strong correlation between the two phenomena, with some of (...) them believing that they are directly equated. On the other hand, there are several researchers who consider populism as a phenomenon with its own unique essence without predetermined characteristics. Hence, the question that arises here is: Is conspiracism endogenous to populism, or not? In this article, I first look at the definitions of conspiracy theories/conspiracism and populism, attempting to avoid stereotypical readings. After that, I highlight the discussion that takes place in academia around the internal features of the populist phenomenon and its possible connection with conspiracism, with the aim of showing that populism presents a unique logic, without a necessary connection to conspiracism. Finally, I focus on the Greek case of recent years, describing an example where the concept of conspiracy theory became a polemical tool against political rivals, negatively affecting politics and society. My analysis is based on post-structuralist theory and methodological tools of the Essex School of Discourse Analysis, taking into account aspects of other approaches to populism. (shrink)

In this paper art history and visual studies, the disciplines that study visual culture, are presented as a field whose conjectural paradigm can be used to understand the epistemic problems associated with abduction. In order to do so, significant statements, concepts and arguments from the work of several specialists in this field have been highlighted. Their analysis shows the fruitfulness and potential for understanding the study of visual culture as a field that is interwoven with the assumptions of abductive cognition.

A publicação de 2007, Homo Sacer II, 2, Il Regno e la Gloria, constitui marco na obra agambenana. Por um lado, o projeto Homo Sacer, que tinha por objetivo a genealogia do poder político, ascende a nova e decisiva dimensão: desvela o paradigma da teologia econômica, que permite explicar com maior precisão a articulação entre o reino e o governo, e os alcances do diagnóstico biopolítico. Por outro, Agamben crê haver encontrado nesse livro o arcano do poder: a glória. A (...) concepção da política como administração, ὀιχονομία, governo no qual a onipresença da economia expande-se por todos os aspectos da vida social é índice do movimento que alcança na glória sua máxima expressão.

El artículo se pregunta por el problema del Otro en América Latina, considerando la reflexión de Lévinas y de Ortega y Gasset a partir de la fenomenología de Husserl. El examen recae en dos figuras paradigmáticas de la modernidad barroca: la así denominada Malinche y Juana Inés de la Cruz, teniendo como telón de fondo el debate entre Ginés de Sepúlveda y Bartolomé de las Casas acerca de la humanidad o animalidad de los así llamados indígenas. Se le presta especial (...) atención a las perspectivas adoptadas por Tzvetan Todorov, Leopoldo Zea, Octavio Paz y Bolívar Echeverría sobre las figuras mencionadas. (shrink)

The aim of this text is to examine the issue of truth telling in doctor-patient relationships, namely in the case of terminal patients. We analyze the problems and attitudes regarding truth telling that there are present when patients suffer from mortal diseases. We conclude that it is very important to keep a fluent and truthful communication in the doctor-patient relationship. We also examine and stress the role that general practitioners can play in the care of terminal patients at their home (...) and with their friends and/or relatives. (shrink)

Gentile's philosophy merits the attention of every serious thinker, for it presents the doctrine that reality is spiritual in a more uncompromising form than is to be found elsewhere, and claims to solve on this principle all the great problems that have beset the history of metaphysic. His own name for it is Absolute or Actual Idealism . For Gentile, nothing is real but the Spirit, and by the Spirit he means the pure act of self-conscious thinking. “The subject that (...) conceives itself in conceiving All is the reality itself.” In the act of conscious thinking, the Spirit is present in its entirety as subject ; generating therein by its own creative spontaneity a world of objects, and resolving the products of this act of objectification into the womb that gave them birth. In this immanent dialectic–pure subject , pure object , subject-object –lies the rhythmic life-history of the Spirit. “Our doctrine,” writes Gentile, “is the theory of the Spirit as act which posits its object in a multiplicity of objects, resolving their multiplicity and objectivity in the unity of the subject itself.” For such a doctrine, transcendence is the enemy, the Goliath whom Gentile has gone forth to slay. He confronts us, on almost every page of his writings, with an ineluctable dilemma. Either a philosophy of sheer immanence, or reality is unknowable. (shrink)
