In tourism, the presence of different stakeholders, sometimes with conflicting interests, requires a clear understanding of how to manage and engage them effectively. Despite the importance of this topic, tourism studies lack a univocal framework for destinations aiming to develop a destination management system (DMS) focused on empowering stakeholder engagement. To fill this gap, this study aims to identify the key dimensions that can strengthen stakeholder engagement in the tourism sector. Particular attention is given to the role of technology in (...) mediating relationships among DMS participants and to the role of ‘intermediary’ stakeholders in facilitating collaboration and engagement. By adopting a cross-disciplinary approach that integrates stakeholder theory, stakeholder engagement and destination management, and by examining a case study of an Italian best practice, DMS Puglia, a technology-enabled framework for stakeholder engagement in a DMS was elaborated. This study contributes to the advancement of the literature on stakeholder engagement in tourism by demonstrating that the structure and composition of a DMS, and the communication methods it enables, along with the role of the destination management organisation and the preparedness of stakeholders to participate in a DMS, significantly influence stakeholder engagement and can strengthen relationships among participants in a technologically advanced tourism system. This study also provides directions to stakeholder bridges about how to effectively improve stakeholder engagement through technology-focused tools and strategies. (shrink)

I present an argument proving that there are no fundamental facts, which is similar to an argument recently presented by Mark Jago for truthmaker maximalism. I suggest that this argument gives us at least some prima facie, defeasible reason to believe that there are no fundamental facts.

This paper argues that some of the misunderstandings surrounding the meaning and function of the concept of human dignity in bioethics arise from a lack of distinction between two different roles that this notion plays: one as an overarching policy principle, and the other as a moral standard of patient care. While the former is a very general concept which fulfils a foundational and a guiding role of the normative framework governing biomedical issues, the latter reflects a much more concrete (...) and context-specific understanding of the patient as a “person”. The importance of dignity as a policy principle will be described by appealing to the distinction between principles and rules as developed by some legal philosophers. The value of dignity as a standard of patient care will be illustrated with the help of concrete examples and by drawing on the taxonomies of dignity proposed by Jonathan Mann and other scholars. The overall scope of the article is to highlight this double and complementary role of human dignity in bioethics. (shrink)

Management of different types of partnerships plays a decisive role in company performance. Complex business ventures, such as those created to serve low-income populations, usually include both cross- and same-sector partnerships. However, the initial diversity featured in these alliance portfolios diminishes as companies take their ventures up to scale. This article develops theoretical propositions about the evolution and configuration patterns of portfolios that include both cross- and same-sector partnerships. Two longitudinal case studies serve to illustrate the theoretical framework developed for (...) alliance portfolios that include both types of partnerships. Companies that create such portfolios adopt partnership strategies that follow paths also identified in the evolution of portfolios only made up of partnerships with other private firms: i.e., an evolution from adapting to shaping and exploiting strategies.

The article deals with the lines along which manifold senses of horizonedness emerge and their reference to potentiality as a starting-point. The first section examines Gurwitsch's analyses of field-potentialities and margin-potentialities in the light of distinctions drawn by Husserl in terms of latency and patency. It is contended that Husserl's concept of latency encompasses both modes of potentiality. The second section shows how the world- horizon functions as a background- horizon and alternation- horizon conceived of as the two fundamental modes (...) of non-thematic consciousness. In this respect, an attempt is made to link this theme with Gurwitsch's description of the acquisition of the character of positional index as a worldly existent. The third section is concerned with how potentiality develops into an all-encompassing domain that can be anticipated as an ideal totality and into a pregiven ground, and outlines an approach to the complementarity of this threefold characterization. This development falls out of Gurwitsch's framework for the analysis of horizonedness. The article concludes with a characterization of the encasement-of-one-in-another of horizons. Reasons are suggested for the application of some ideas of Gurwitsch on thematic transformation to this sequence of levels. (shrink)

In the recent literature across philosophy, medicine and public health policy, many influential arguments have been put forward to support the use of randomization procedures to allocate scarce life-saving resources. In this paper, I provide a systematic categorization and a critical evaluation of these arguments. I shall argue that those arguments justify using RAND to allocate SLSR in fewer cases than their proponents maintain and that the relevant decision-makers should typically allocate SLSR directly to the individuals with the strongest claims (...) to these resources rather than use RAND to allocate such resources.

The duality theory established by Halmos in [2] for boolean hemimorphism applies of course to the diagonalizable algebra, because ντν is an hemimorphism. For commodity in working on diagonalizable algebras we recall the basic facts and give the characteristic conditions on the dual of ντν.

Over the last decade, several European countries and the Council of Europe itself have strongly supported the use of advance directives as a means of protecting patients’ autonomy, and adopted specific norms to regulate this matter. However, it remains unclear under which conditions those regulations should apply to people who are placed in correctional settings. The issue is becoming more significant due to the increasing numbers of inmates of old age or at risk of suffering from mental disorders, all of (...) whom might benefit from using advance directives. At the same time, the closed nature of prisons and the disparate power relationships that characterise them mean that great caution must be exercised to prevent care being withdrawn or withheld from inmates who actually want to receive it. This paper explores the issue of prisoners’ advance directives in the European context, starting with the position enshrined in international and European law that prisoners retain all their human rights, except the right to liberty, and are therefore entitled to self-determination regarding health care decisions.

Joseph Keim Campbell has recently criticized Peter van Inwagen's Third Argument against compatibilism for its reliance on the existence of a remote past. In response, Anthony Brueckner has offered a new version of the Third Argument showing that determinism and free will are incompatible for all times t relative to which there is a past . In this paper I argue that although Brueckner's retooled argument fails to prove anything in favour of incompatibilism, its conclusion can be exploited to provide (...) another version of van Inwagen's original argument that doesn't rely on the existence of past times, thus withstanding Campbell's criticism.

Decision theorists have attempted to accommodate several violations of decision theory’s axiomatic requirements by modifying how agents’ choice options are individuated and formally represented. In recent years, prominent authors have worried that these modifications threaten to trivialize decision theory, make the theory unfalsifiable, impose overdemanding requirements on decision theorists, and hamper decision theory’s internal coherence. In this paper, I draw on leading descriptive and normative works in contemporary decision theory to address these prominent concerns. In doing so, I articulate and (...) assess several different criteria for individuating and formally representing agents’ choice options. (shrink)

El artículo analiza el vínculo entre derecho y violencia en Walter Benjamin y Franz Rosenzweig. Primero, se estudia la relación entre Benjamin, Rosenzweig y Carl Schmitt, y, a continuación, la proximidad entre las concepciones benjaminiana y rosenzweiguiana de la historia y de la temporalidad mesiánica, así como la relación entre justicia, derecho y eternidad. Finalmente, se presenta la propuesta derridiana de una deconstrucción de la crítica benjaminiana de la violencia y su antecedente en _La estrella de la redención_.

This is Dr. Roberto Assagioli's second book on the psychological system he formulated known as Psychosynthesis. It continues where his first book left off and delves into the important process of willing as a psychological function based on a higher self rather on guilt or determination as in the Victorian concept of the will.

After Husserl and Heidegger, phenomenology has attempted to push the reduction beyond the reference of objects to the performances effected by consciousness, or of beings to Being. First, a new level of the reduction comes forth in M. Henry's radical reduction of appearing to the appearing of appearing, and leads to the disclosure of a dimension in which no horizons are to be fulfilled because the superabundance of life holds sway. Secondly, according to H. Rombach, the phenomena decribed in the (...) first two levels are nothing but epiphenomena, and must be explained in terms of structures that emerge in a creative development. Reality brings forth something from itself, and we must take advantage of this contribution in order to obtain more than what is anticipated in our projects. Thirdly, J.-L. Marion advances a theory on saturated phenomena in order to account for phenomena that surpass the bounds outlined for them in the mere significational intentions because they show a surplus of intuition. The three trends lead respectively to an originary phenomenality, an outbreak of phenomena, and saturated phenomena. The article contends that they tend to come together because they link the third level of phenomenology to a reflection that turns on the duality between what appears and its appearing, and, in doing so, disclose a surplus with regard to three different aspects of the duality, i.e., appearing as such, the overall condition of what appears, or the appearing of some preeminent phenomena. Finally, some anticipations of these trends in Husserl's transcendental phenomenology are shown.Luego de Husserl y Heidegger, la fenomenología ha intentado llevar la reducción más allá de la referencia de los objetos a las operaciones efectuadas por la conciencia o de los entes al ser. En primer lugar, un nuevo nivel de reducción se manifiesta en la reducción radical propuesta por M. Henry para retroceder del aparecer al aparecer del aparecer, y conduce al descubrimiento de una dimensión en que no hay horizontes que puedan ser plenificados porque impera la sobreabundancia del la vida. En segundo lugar, según H. Rombach, los fenómenos descritos en los dos primeros niveles no son otra cosa que epifenómenos y tienen que ser explicados en términos de estructuras que emergen en un desarrollo creador. La realidad produce algo a partir de sí misma, y esta contribución debe ser aprovechada a fin de alcanzar más de lo anticipado en nuestros proyectos. En tercer lugar, J.-L. Marion presenta una teoría sobre los fenómenos saturados a fin de dar cuenta de aquellos casos que exceden los límites que les han sido delineados en las intenciones significativas vacías porque muestran una demasía de intuición. Las tres tendencias conducen respectivamente a una fenomenalidad originaria, a un estallido del fenómeno y a una saturación del fenómeno. El artículo sostiene que tienden a converger porque vinculan el tercer nivel de la fenomenología con una reflexión en torno de la dualidad entre lo que aparece y su aparecer, y que, al hacerlo, ponen de manifiesto una excedencia respecto de tres aspectos distintos de la dualidad, esto es, el aparecer en cuanto tal, la condición general de lo que aparece o la aparición de algunos fenómenos preeminentes. Finalmente, se indican algunas anticipaciones de estas tendencias en la fenomenología trascendental de Husserl. (shrink)

We investigate certain Brouwer-Zadeh lattices that serve as abstract counterparts of lattices of effects in Hilbert spaces under the spectral ordering. These algebras, called PBZ*-lattices, can also be seen as generalisations of orthomodular lattices and are remarkable for the collapse of three notions of “sharpness” that are distinct in general Brouwer-Zadeh lattices. We investigate the structure theory of PBZ*-lattices and their reducts; in particular, we prove some embedding results for PBZ*-lattices and provide an initial description of the lattice of PBZ*-varieties.

The problem of future contingents is one of the most ancient and debated puzzles in Western philosophy, and Supervaluationism is, today, one of the most prominent solutions to the problem. Recently, John MacFarlane has carried a well-known criticism to Supervaluationism and put forward a new solution of the problem of future contingents, which is known as Double Time Reference Theory. Here, we compare DTRT with Supervaluationist semantics, and we show that the success of MacFarlane's criticism crucially depends on the expressivity (...) of the language adopted. Once a reasonable expressive power is granted, however, MacFarlane's criticism no longer applies. (shrink)

Most discussions of Rawls’s philosophy tend to neglect the strong communitarian strand of his theory: so much so that in the debate between liberals and communitarians Rawls’s account of community has been for the most part intriguingly absent. This article is an attempt to fill in the gap by offering a discussion of the Rawlsian understanding of community as it was presented in A Theory of Justice and its possible implications for a pluralist society. At the same time, I want (...) to take issue with one of the most influential critiques leveled against Rawls’s conception of the self: namely, Sandel’s critique of the ‘individuated subject’ that, in his view, underlies justice as fairness. Rawls’s constructions, so Sandel argues, rest on an unencumbered self that is individuated in advance and whose identity is fixed once and for all. (shrink)

En el curso de 1934/35 Heidegger se refiere a cuatro momentos esenciales del temple fundamental: desplazamiento hacia los límites del ente, inserción en la existencia histórica y arraigo en la tierra y el suelo natal, apertura del ente en conjunto como la unidad de un mundo, y fundación del ser. El artículo explora el vínculo de los cuatro momentos con las siguientes oposiciones: indigencia/disponibilidad, no-hogareño/hogareño, duelo/alegría, lejanía/cercanía y condición-de-oculto/condición-de-no-oculto. Se analiza esta quinta oposición en relación con las diversas modalidades en (...) que se manifiesta el ánimo. Las oposiciones pueden ser consideradas también rasgos distintivos del temple fundamental. Se interrelacionan, y, además, se despliegan siempre a partir de una intimidad fundamental que opera como un nexo en medio de los antagonismos. El énfasis está puesto en el curso de 1934/35 con referencias a ulteriores textos complementarios. (shrink)

Antonio Gramsci's _Prison Notebooks_ have offered concepts, categories, and political solutions that have been applied in a variety of social and political contexts, from postwar Italy to the insurgencies of the Arab Spring. The contributors to _Gramsci in the World_ examine the diverse receptions and uses of Gramscian thought, highlighting its possibilities and limits for understanding and changing the world. Among other topics, they explore Gramsci's importance to Caribbean anticolonial thinkers like Stuart Hall, his presence in decolonial indigenous movements in (...) the Andes, and his relevance to understanding the Chinese Left. The contributors consider why Gramsci has had relatively little impact in the United States while also showing how he was a major force in pushing Marxism beyond Europe—especially into the Arab world and other regions of the Global South. Rather than taking one interpretive position on Gramsci, the contributors demonstrate the ongoing relevance of his ideas to revolutionary theory and praxis. Contributors.

This paper compares the conception of substantial change put forth by Peter of Mantua (d. 1399) in his De primo et ultimo instanti with the one developed by Albert of Saxony (ca. 1320–1390). According to Albert, (i) each substantial form, save for the intellective soul, is a spatially-extended entity with actual quantitative parts that are co-located with the parts of matter they inform, and (ii) these quantitative parts are generated and corrupted one after another over an extended interval of time. (...) From (i) and (ii), Albert deduces that (iii) the substantial change of material substances as individuals (save for human beings) is a temporally extended process. This is what I call the ‘piecemeal’ conception of substantial change. I show that Peter of Mantua is significantly indebted to this conception. Indeed, he endorses both (i) and (ii). Moreover, he even extends this approach to the process by which the intellective soul informs matter and is separated from it. Nevertheless, I argue that, thanks to his peculiar doctrine of numerical sameness over time, Peter rejects (iii) and maintains, instead, that the substantial change of any material substance as an individual is an instantaneous event.

Os chamados manuscritos C, recentemente publicados, têm um interesse especial para a clarificação da constituição do mundo na medida em que mostram como, a partir de um mundo primordial ou quasi-mundo correlato à pré-intencionalidade, se atinge o mundo plenamente intersubjetivo constituído por uma intencionalidade de interesses desde uma práxis comunicativa. Seguindo os manuscritos, este artigo tem um propósito quádruplo: 1) tentar discernir diferentes caracterizações do mundo como horizonte universal, representação-mundo, todo, forma, idéia e fundamento; mostra-se, assim, o papel da temporalidade (...) na raiz desses traços de mundanidade; 2) níveis de constituição do mundo são desvelados a fim de diferenciar um fundamento previamente dado de um fundamento que se desenvolve através dos estágios do mundo egóico, mundo da casa, mundo da vida e mundo-em-si; desvela-se aqui um encaixamento desses horizontes um no outro; 3) uma análise posterior dos níveis é dada através do questionamento retroativo na primalidade como um retrocesso que revela o desenvolvimento de um pré-mundo a um mundo genuíno; uma gênese permanente, antes de uma gênese do passado, é realçada; 4) finalmente, mostrar- se-á como antecipações da fenomenologia póshusserliana nos remetem a uma abertura originária do mundo em sua mundanidade, um âmbito que é anterior à manifestação de um mundo de objetos e uma ordem de manifestação diferente daquela do mundo. PALAVRAS-CHAVE – Fenomenologia genética. Husserl. Manuscritos C. Mundo. Temporalidade. ABSTRACT The recently published C-manuscripts hold special interest for the clarification of the constitution of the world by showing how, starting from a primal or quasiworld correlated with preintentionality, it advances to the full intersubjective world constituted by an intentionality of interests within communicative praxis. Following the manuscripts, this paper has a fourfold purpose. First, it attempts to discern different characterizations of the world as universal horizon, world-representation, whole, form, idea, and ground. The role of temporality at the roots of these traits of worldliness is shown. Second, levels of constitution of the world are disclosed in order to differentiate a readymade ground from a ground that develops through the stages of egoical world, homeworld, lifeworld, and world-in-itself. An encasement of these horizons one-in another is displayed. Third, a further analysis of levels is given through the inquiry back into primality as a retrogression that reveals the development from a pre-world to a genuine world. A permanent genesis rather than a past genesis is brought out. Finally, anticipations will be shown of post-Husserlian phenomenological views regarding an originary openness of the world in its worldliness, a realm that is prior to the manifestation of a world of objects, and a different order of manifestation than that of the world. KEY WORDS – Genetic phenomenology. Husserl. C-manuscripts. World. Temporality. (shrink)

El propósito del artículo es esclarecer el modo en que los principales problemas tratados por J. Iribarne giran en torno de cuestiones éticas. Se subrayan dos lados del problema ético. Por un lado, se muestra el papel del cuerpo propio, la habitualidad, la memoria y la creciente moralización en la constitución de la identidad personal. En este proceso, una teleología individual se dirige hacia grados más elevados de libertad por medio de actos autónomos y racionales. Por el otro, una teleología (...) intersubjetiva da lugar a un habitar ético en el mundo que exige tanto actuar del modo más correcto de acuerdo con nuestras particulares posibilidades como estar vinculado con los otros por medio de lazos de amor. Finalmente se intenta mostrar la relación entre ética y el sentido de la vida a través de un análisis de preguntas referidas a la finitud, la esperanza y la muerte.The purpose of the article is to shed light on the way in which the main problems examined by J. Iribarne turn on ethical issues. Two sides of the ethical problem are stressed. On the one hand, the role of the living body, habituality, memory, and increasing moralization in the constitution of personal identity is highlighted. In this process, an individual teleology is directed to higher degrees of freedom by means of autonomous and rational acts. On the other hand, an intersubjective teleology brings forth an ethical dwelling in the world that entails both acting in the most correct manner according to our particular possibilities and being linked with the others by bonds of love. Finally, an attempt is made to show the relationship between ethics and the meaning of life through an analysis of issues that concern finitude, death, and hope. (shrink)

Along with a static and genetic egological inquiry, Husserl offers a nonegological analysis that advances through different levels or stages of history. Basic phenomenological themes—subjectivity, temporality, intersubjectivity, and worldliness—appear in varying figures with the progressive bringing-into-play of levels that concern conditions of possibility, actual development, and rational goals. In addition, post-Husserlian phenomenology discloses a surplus that brings us to a level outside the reach of history. This scheme confronts us both with the enduring issue of the stratification of reality and (...) with Maurice Merleau-Ponty's contention that philosophical problems are concentric. In order to shed light on these levels and figures, and thus to set in order the main themes of human experience, an attempt might be made to clarify the relationship between them in terms of the determinateness and indeterminateness of horizonality. As for every such level, there emerges a varying stage of rational legitimation; new advances could also be made with regard to the perennial problem of the unity of reason in the midst of its diversity.

El primer apartado del trabajo considera cómo el pensar es privado de su carácter primario cuando la lógica originaria y el lenguaje de las señas son sustituidos por la lógica del enunciado y el lenguaje de los signos. En segundo lugar, se muestra que la elucidación de las señas del Ser conduce a un examen del peligro que enfrenta el pensar en presencia de la filosofía. El tercer apartado se ocupa del ulterior peligro que surge cuando se intenta derivar el (...) pensar a partir del poetizar. El pensador aguarda señas porque ya no cuenta con sistemas de pensamiento, y en este proceso ha de estar dispuesto para la verdad del ser. Mientras que el poeta instituye de una manera originaria el Ser en una comunidad, el pensador concibe y ensambla, y de ese modo abre por primera vez lo que ha sido desvelado por el poeta. Finalmente, se ofrece un análisis de la relación de la lógica originaria con la hermenéutica y la fenomenología. (shrink)

This collection of essays by scholars from Europe, Asia, North America, and Latin America offers new perspectives of the phenomenological investigation of experiential life on the basis of Husserl’s phenomenology. Not only well-known works of Husserl are interpreted from new angles, but also the latest volumes of the Husserliana are closely examined. In a variety of ways, the contributors explore the emergence of reason in experience that is disclosed in the very regions that are traditionally considered to be “irrational” or (...) “pre-rational.” The leading idea of such explorations is Husserl’s view that perception, affectivity, and volition are regarded as the three aspects of reason. Without affectivity, which is supposedly irrational, no rationality can be established in the spheres of representation and volition, whereas volitional and representational acts consistently structure the process of affective experience. In such a framework, it is also shown that theoretical and practical reason are inseparably intertwined. Thus, the papers collected here can be regarded as a collaborative phenomenological investigation into the entanglement and mutual dependency of the supposedly “rational” and the “irrational” as well as that of the “practical” and the “theoretical.”.

El trabajo tiene como hilo conductor la diferenciación efectuada por P. Ricoeur respecto del lenguaje entre la lengua, el discurso oral, la escritura y la lectura. Cada uno de estos modos de lenguaje puede ser examinado según los fenómenos de la temporalidad, la subjetividad, el mundo y la intersubjetividad. Siguiendo a M. Presas, este esquema se aplica al arte y a su función de dejar que las cosas se manifiesten en su plena presencia. Se destaca su énfasis en la liberación (...) efectuada por el arte respecto de la limitación fáctica de nuestra situación finita. Esto se logra mediante la apertura a la verdad de una existencia posible que no se identifica con una evasión de la realidad. Los análisis de Presas se centran en P. Klee y F. Marc, y destacan los rasgos distintivos relacionados con los mencionados fenómenos. En el intento de ofrecer un complemento a este examen, se mencionan las interpretaciones de Merleau-Ponty sobre P. Cézanne, de M. Henry sobre V. Kandinsky y de J.-C. Marion sobre G. Courbet. Se muestra que en ellas también se encuentran explicitaciones de lo que Presas ha afirmado sobre la discordia, el ser insular y la ausencia de apremio. (shrink)

This paper is concerned with a logical system, called Brouwer-Zadeh logic, arising from the BZ poset of all effects of a Hilbert space. In particular, we prove a representation theorem for Brouwer-Zadeh lattices, and we show that Brouwer-Zadeh logic is not characterized by the MacNeille completions of all BZ posets of effects.

Starting with Popper, philosophers and logicians have proposed different accounts of verisimilitude or truthlikeness. One way of classifying such accounts is to distinguish between “conjunctive” and “disjunctive” ones. In this paper, we focus on our own “basic feature” approach to verisimilitude, which naturally belongs to the conjunctive family. We start by surveying the landscape of conjunctive accounts; then, we introduce two new measures of verisimilitude and discuss their properties; finally, we conclude by hinting at some surprising relations between our conjunctive (...) approach and a disjunctive account of verisimilitude widely discussed in the literature.

This article critically examines two central concepts in normative theory—ethical life and morality—by comparing the pragmatist approach with that of Critical Theory. This is done by way of a close scrutiny of Axel Honneth’s reading of the pragmatist philosophers John Dewey and George H. Mead. This focus on Honneth’s use of pragmatism serves as a port of entry to provide a comparative analysis of pragmatism and Critical Theory’s approaches to normativity. As I intend to show, Honneth’s troubles with making sense (...) of the pragmatist approach to normativity are a litmus test of some persistent ambiguities at the heart of his understanding of normativity. I set the stage by reconstructing Honneth’s reading of Dewey and Mead. That will provide the background against which to set up a comparison between the pragmatist conception of normativity and that of Critical Theory, with a view to assessing their relative validity. I then relate Honneth’s reading of the pragmatists to his own philosophical project and to the important place occupied in it by the same dualism of ethical life and morality. (shrink)

Any living organism interacts with and responds specifically to environmental molecules by expressing specific olfactory receptors. In this paper, this specificity will be first examined in causal terms with particular emphasis on the mechanisms controlling olfactory gene expression, cell-to-cell interactions and odor-decoding processes. However, this type of explanation does not entirely justify the role olfactory receptors have played during evolution, since they are also expressed ectopically in different organs and/or tissues. Homologous olfactory genes have in fact been found in such (...) diverse cells and/or organs as spermatozoa, testis and kidney where they are assumed to act as chemotactic sensors or renin modulators. To justify their functional diversity, homologous olfactory receptors are assumed to share the same basic role: that of conferring a self-identity to cells or tissues under varying environmental conditions. By adopting this standpoint, the functional attribution as olfactory or chemotactic sensors to these receptors should not be seen either as a cause conditioning receptor gene expression, or as a final effect resulting from genetically predetermined programs, but as a direct consequence of the environmental conditions olfactory receptor genes have explored during evolution. The association of odorant patterns with specific environmental or contextual situations makes their relationship semiotically triadic, due to the emergence of an interpretant capable of perceiving odorants as meaningful signs out of a noisy background. This perspective highlights the importance of odorant-receptor relationships as respect to the properties of the interacting partners. It is our contention that only when taken together can these different explanatory strategies provide a realistic account of how olfactory receptor genes have been structurally and functionally modified during evolution.

Este artigo constitui-se num exercício de refiguração de uma noção filosófica e literária clássica no âmbito da estética contemporânea, cuja referência é a tragédia Persas, de Ésquilo, a saber, o conceito de hýbris. Este, na figura de Xerxes, manifesta-se em sua soberba ao tentar derrotar os gregos, comandando numeroso exército na batalha de Salamina. Punido pelos deuses por tal desmedida, no êxodo da obra, surge como um imperador derrotado, trajando esfarrapadas vestes reais. Num diálogo com a arte na contemporaneidade, a (...) discussão empreendida pelo artigo é a de refigurar o mencionado conceito como presença potente na manifestação performática criada por Hélio Oiticica: os parangolés. Com esse intuito, este texto está dividido em três movimentos fundamentais: a) a apresentação dos fundamentos clássicos da hýbris, b) a problematização da presença deste conceito na tragédia Persas, de Ésquilo e, finalmente, c) a transmutação por que passa o conceito de hýbris, da perspectiva negativa clássica, presente na tragédia grega, para a estética positiva contemporânea, ostentada nos parangolés de Oiticica.
