In this paper we investigate a particular two-stage supply chain network design problem with fixed costs. In order to solve this complex optimization problem, we propose an efficient hybrid algorithm, which was obtained by incorporating a linear programming optimization problem within the framework of a genetic algorithm. In addition, we integrated within our proposed algorithm a powerful local search procedure able to perform a fine tuning of the global search. We evaluate our proposed solution approach on a set of large (...) size instances. The achieved computational results prove the efficiency of our hybrid genetic algorithm in providing high-quality solutions within reasonable running-times and its superiority against other existing methods from the literature.

On the Beginnings of the Greek Doctrine of the Transmigration of Souls. In this article, I state that attendant on the acceptance of the idea of an immortalsoul is a legitimate question concerning the soul's status before the individual's birth and after its death. Whether the Greeks were the originators of the doctrine of the transmigration of souls or this was an influence from another culture is still open to debate.

The research on stem cell-based therapies has greatly expanded in recent years. Our text attempts to seek those religious and ethical challenges that stem cell therapy and research bring into debate. Our thesis is that bioethics can defend its principle without a religious background. We will develop our argumentation on three major points: firstly, a comparison between secular ethics and religious views will clarify why stem cell therapy and research are important from a scientific point of view, addressing the very (...) center of the human being; in our view, being based on secular society, bioethics can answer the challenges of stem cell therapy and research; secondly, following Hans Jonas' perspective on experimenting on humans, we seek to understand the philosophical guidance that sciences dealing with stem cell need; thirdly, we will map the ethical guidelines for clinical translational research that have been adopted by the International Society for Stem Cell Research. .

This paper deals with Descartes’s and Roberval’s attempts to devise and describe the center of agitation of a composite pendulum. This episode has received some attention in the recent literature. It is usually depicted as the first step in the development of a general procedure for establishing the center of oscillation of a pendulum. My aim is to explore the different physical concepts and assumptions which informed the two mathematical accounts of the composite pendulum. I will argue that force, agitation, (...) heaviness, or resistance of air essentially meant different things for Descartes and Roberval. As a result, the physical phenomena covered by the two geometrical procedures were quite distinct, and both mathematicians envisaged different roles of these phenomena within their agenda of studying nature.

The purpose of this paper is to lay out the similarities between the philosophical projects of Patočka and Merleau-Ponty, with respect to the question of the “limits of phenomenology”. We suggest that both these authors propose two complementary strategies in their attempt of overcoming the Husserlian phenomenology. The first one consists in extending the field of phenomenology so as for it to be able to encompass phenomena either insufficiently explored or misinterpreted by the conceptuality that Husserl put forth; the second (...) strategy, more ambitious, aims to overpass the very standpoint of phenomenology in favour of an ontological approach. We try to show that what profoundly motivates these attempts is a radical – and hence, ontological – reinterpretation of the Lebenswelt. (shrink)
My paper aims at laying out the main tenets of Patočka’s unusual and highly provocative position with regard to the question of history, drawing essentially on his Heretical Essays on the Philosophy of History, while also gathering insights from other works such as Eternity and Historicity and Europe and post-Europe. In the first part, I set in place the overall framework of this analysis, and show that three distinct, yet entwined concepts of history are operative in Patočka’s work: the understanding (...) of history as a specific regime of meaning, as an existential possibility of the human Dasein, and as a “epochal” dynamic. In the second part, I reconstruct the criticism Patočka mounts against the classical philosophies of history and indicate that his rejection of a teleological account of history is compatible with the attempt of establishing an intrinsic correlation between meaning and history. In the final part, I stress the importance acquired by the experience of the “shattering of meaning” for Patočka’s threefold understanding of history and argue for the possibility of crafting a unitary framework which would encompass his analysis.

The main goal of my inquiry is to lay out the proximity between Patočka’s and Ricœur’s readings of Husserl’s Krisis and to stress the role played by the concept of the life-world in the unfolding of their original philosophical undertakings. In the first part, I show the importance both Patočka and Ricœur assignedto the Husserlian project of an “ontology of the life-world”. In the second part, I expose the criticism these two authors addressed to Husserl’s understanding of the life-world and, (...) more precisely, to the idea that the exploration of the life-world is merely another way of gaining access to transcendental subjectivity. In the last part, I show how the concrete descriptions of the life-world given by Patočka and Ricœur depart massively from the Husserlian perspective. (shrink)
Le projet d’une «cosmologie philosophique» que Fink formule dans ses écrits de l’après-guerre est animé par l’exigence de «penser le monde lui-même». Je me propose de faire ressortir l’originalité de ce programme philosophique à travers un examen critique de deux conceptions du monde concurrentes. Ainsi, j’explicite les critiques que Fink adresse à la compréhension du monde comme «totalité de l’étant», centrale pour la tradition métaphysique, et à l’entente existentiale comme «horizon de la praxis humaine», déterminante pour l’ontologie fondamentale de Heidegger. (...) Au terme de cette enquête, il apparaît que la conception finkéenne du monde comme «processus d’individuation» représente une voie singulière, située par-delà l’alternative entre un concept chosique et un concept existential de monde.

Subjectivity and Project. Patočka's critique of Heidegger's concept "project of possibilities" The purpose of this article is to lay out the way the main aspects of Patočka's critical reading of Heidegger's fundamental ontology. More precisely, I intend to restate the central arguments Patočka raised against Heidegger's characterization of "understanding" as a "project". In the first part, I will single out Patočka's project of an "asubjective phenomenology" by distinguishing it from another asubjective project and from the subjective phenomenology. In the second (...) part, I will examine some central theses Heidegger puts forth in §31 of Being and Time in order to show the inescapable difficulties they bring about. In the final part, I will describe the tenets around which Patočka's critical reading of Heidegger revolves. I will explore the two directions of this critique that correspond to the double orientation of asubjective phenomenology: a) on the one hand, the priority of the phenomenal field with regard to any subjective sense-bestowal; b) the importance of the phenomenon of corporeity for an accurate apprehension of subjectivity.

The purpose of this enquiry is to lay out the core features of Garelli’s conception of the world as a “pre-individual field,” as they emerge from his confrontation with Heidegger’s thought. In the first part, I am exploring Garelli’s interpretation of the “poetical expression” and the consequences he draws from it with regard to the process of “worlding”. Then, I am restating his criticism with regard to the concept of the world Heidegger developed within the framework of “fundamental ontology” and (...) show why, on Garelli’s account, an understanding of the world as an “existential structure of Dasein” fails to grasp its proper meaning. In the final part, I expose Garelli’s objections to Heidegger’s later understanding of the world as “Fourfold” and underline the dependency of this conception on a set of assumptions which perpetuate the theoretical privilege of individual being.

The encounters of the Romanian philosopher C. Noica with his youger disciples - Gabriel Liicean, Andrei Pleșu, Sorin Vieru et alii - in the transylvanian Carpathian mountains, in the Păltiniș resort were perceived by Noica’s followers as a real philosophical school and an idealistic alternative to the compulsory marxist ideology. In spite of that, the orthodox thinker and literary critic N. Steinhardt took it as a way of avoiding the tough reality of communism and a negation of the Christian religion. (...) Therefore, he criticised that option and the pretention of the “Păltiniș School” to create a viable alternative to the officially imposed marxist vision. Steinhardt’s article received critical answers not only from the members of the so-called School, but also from another thinker and literary critic, Adrian Marino, who thought that both Noica and Steinhardt are wrong and the younger thinkers should act against Nicolae Ceaușescu’s agressive dictatorship by meas of civic and democratic activity. The study tries to emphasize the existence of more than one alternative to the communist ideology in Romania’s 1980s, generally considered as a frozen epoch for free philosophical and politically relevant discussions.
