Ce petit article explicite brièvement le contexte de l�article qui précède et en retrace le parcours en montrant comment le philosophe s�approche prudemment des notions clés de la théologie chrétienne.

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)

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)

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)

BackgroundPreprint usage is growing rapidly in the life sciences; however, questions remain on the relative quality of preprints when compared to published articles. An objective dimension of quality that is readily measurable is completeness of reporting, as transparency can improve the reader’s ability to independently interpret data and reproduce findings.MethodsIn this observational study, we initially compared independent samples of articles published in bioRxiv and in PubMed-indexed journals in 2016 using a quality of reporting questionnaire. After that, we performed paired comparisons (...) between preprints from bioRxiv to their own peer-reviewed versions in journals.ResultsPeer-reviewed articles had, on average, higher quality of reporting than preprints, although the difference was small, with absolute differences of 5.0% [95% CI 1.4, 8.6] and 4.7% [95% CI 2.4, 7.0] of reported items in the independent samples and paired sample comparison, respectively. There were larger differences favoring peer-reviewed articles in subjective ratings of how clearly titles and abstracts presented the main findings and how easy it was to locate relevant reporting information. Changes in reporting from preprints to peer-reviewed versions did not correlate with the impact factor of the publication venue or with the time lag from bioRxiv to journal publication.ConclusionsOur results suggest that, on average, publication in a peer-reviewed journal is associated with improvement in quality of reporting. They also show that quality of reporting in preprints in the life sciences is within a similar range as that of peer-reviewed articles, albeit slightly lower on average, supporting the idea that preprints should be considered valid scientific contributions.

Although narcissists often emerge as leaders, the relationship between leader narcissism and follower performance is ambiguous and often even found to be negative. For women, narcissism seems especially likely to lead to negative evaluations. Since narcissists have the tendency to be impulsive and change their minds on a whim, they may come across as inconsistent. We propose “inconsistent leader behavior” as a new mechanism in the relationship between leader narcissism and follower performance and argue that leader gender plays an important (...) role in whether narcissistic leaders are perceived as inconsistent. Specifically, we expect leader narcissism to have a negative relationship with follower performance through perceived inconsistent leader behavior, especially for female leaders. Thus, we examine leader gender as a personal factor moderating the relationship between narcissism and perceived inconsistent behavior. Also, as perceived inconsistency is likely less problematic when a good relationship exists, we examine leader–member exchange as a contextual condition moderating the relationship between leader behavior and follower performance. We test our moderated mediation model in a multi-source study with 165 unique leader–follower dyads. As expected, leader narcissism was positively related to perceived inconsistent leader behavior, and this relationship was stronger for female leaders. Inconsistent leader behavior was negatively related to follower performance, but only when LMX was low. Our research highlights that perceived behavioral inconsistency can be problematic and—for female leaders—provides an explanation of the negative relation of leader narcissism with follower performance and of the inconsistencies in evaluations of narcissistic leaders’ effectiveness.

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.

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)

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)

We argue that natural language has the right degree of representational richness for false belief reasoning, especially the complements under verbs of communication and belief. Language may indeed be necessary synchronically for cross-modular reasoning, but certain achievements in language seem necessary at least diachronically for explicit reasoning about false beliefs.

En 2011 el señor Mario Posada Ochoa donó a la Universidad EAFIT una extensa y poco conocida colección de arte; acaso unos cuantos amigos habrían visto de cerca las 480 obras que recibió la Universidad, de artistas como Segundo Angelvis, Inés Acevedo Bernal, Sergio Trujillo Magnenat, Luis A. Rengifo y Ramón Vásquez, entre otros. Algunas de ellas carecían de la firma del autor o de un dato que comprobara la autoría, y estaban deterioradas, más que por el tiempo, por el (...) improvisado bodegaje: don Mario las había guardado durante cuarenta años en su hermosa casa de Maracaibo, en el centro de la ciudad. En Extensión Cultural de EAFIT han procurado, desde entonces, conservar este legado. (shrink)

This Special Issue commemorates the 60th anniversary of Business & Society with nine rigorous literature reviews that address important societal problems and provide opportunities for theory development in the business and society field; in this introduction we present an overview of the Special Issue. With the theme “Building on Its Past,” the nine articles address a host of contemporary issues, including climate change, wicked problems, business and human rights, human health, certifications standards, the governance of artificial intelligence, stakeholder engagement, stakeholder (...) theory, and corporate political activity. Together, these reviews offer a wealth of suggested themes, theories and approaches that can drive our research forward for the next decades in business and society research and practice. Using the lens of a miner-prospector continuum to categorize the diversity of articles within this special issue, a common theme emerges across the portfolio of reviews: they all call for a more systemic and integrative perspective toward studying the complex interactions that link business and society actors and issues. Building on these findings, we encourage future scholars to fill long-standing researched gaps through a more open systems approach, which supports both contextually sensitive and multi-level and multi-disciplinary approaches to address grand societal challenges. We conclude with specific suggestions as to how business and society scholars might use an open systems approach, including embracing methodologies to address complex causal pathways, theorizing with a view towards spanning external and internal elements of an organization, and reflecting on the temporal and spatial dynamics of complex systems.

In 1538–39 Francisco de Vitoria delivered two relections:De IndisandDe iure belli.This article distills from these writings the topic of free trade as a “human right” in accordance withius gentiumor the “law of peoples.” The right to free trade is rooted in a more fundamental right to communication and association. The rights to travel, to dwell, and to migrate precede the right to trade, which is also closely connected to the rights to preach, to protect converts, and to constitute Christian princes. (...) This has significant repercussions on the field of business ethics: the right to free trade is ultimately founded directly on natural law and indirectly on divine law; trade is not independent of ethics; and trade is presented as an opportunity to develop the virtues of justice and friendship, among other repercussions. Vitoria is portrayed as a defender of private initiative and free markets. (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)
