Explorées depuis 1924, les fortifications de l’oppidum de Saint‑Blaise dans le Sud de la France ont récemment fait l’objet de nouvelles investigations à l’occasion de la mise en valeur projetée du site.S’ils ont confirmé l’empilement et/ou la succession d’au moins quatre lignes de défense appartenant aux périodes gauloise, tardo-antique et médiévale, ces travaux ont beaucoup renouvelé notre connaissance et notre interprétation de ces murailles, en particulier pour la période protohistorique. Deux points principaux doivent être relevés : l’existence d’un puissant mur (...) gaulois dès la fin du viie s. av. J.‑C., qui nous permet d’identifier ici la forteresse de la tribu gauloise des Ségobriges que les Phocéens ont abordé avant la fondation de Marseille ; la muraille hellénistique en grand appareil de type grec doit désormais être interprétée comme un ouvrage gaulois inachevé, anéanti par les Romains lors de la chute de l’oppidum à la fin du iie s. av. J.‑C. (shrink)

Background: Serious games have shown positive results in increasing motivation, adherence to treatment and strengthening the therapeutic alliance in multiple psychiatric disorders. In particular, patients with impulse control disorders and other disorders in which the patient suffers from inhibitory control deficits have been shown to benefit from serious games.Aim: The aim of this study was to describe the characteristics and to evaluate the usability of a new serious videogame, e-Estesia. This serious videogame was designed to improve emotion regulation in patients (...) with gambling disorder. Preliminary results from a pilot sample are also reported.Method: A pilot sample of 26 patients undergoing treatment for GD was recruited. Participants used e-Estesia on a tablet, which was connected to a thoracic band that sent heart rate and heart rate variability data to the videogame platform in order to provide biofeedback. The System Usability Scale was completed by patients to determine the usability of e-Estesia.Results and Discussion: e-Estesia performed comparatively well for all the explored groups. Around 84.6% of the patients endorsed that it was easy to use. Female patients with GD presented higher HRV during the use of the serious videogame compared to men. (shrink)

Purpose: This systematic review aimed to analyze the impact that the COVID-19 lockdown had on the amount of physical activity performed by university students.Materials and Methods: A systematic electronic search for studies providing information regarding physical activity levels pre and during COVID-19 pandemic in university students was performed up to 20th October 2020 in the databases Cochrane Library, PubMed, SPORTDiscus, and Web of Science. The risk of bias of external validity quality of included studies was assessed by means of those (...) the Newcastle-Ottawa Scale. The quality of the evidence for main outcomes was graded using the Grading of Recommendations Assessment, Development and Evaluation approach.Results and Conclusions: A total of 10 studies were selected. Physical activity levels were assessed by means of questionnaires and accelerometer. Risk of bias was regarded as low and high in six and four investigations, respectively. The quality of evidence was downgraded to low. A significant reduction of physical activity levels were observed in 9 studies. Compared to pre-lockdown values, five studies showed a reduction of light/mild physical activity between 32.5 and 365.5%, while seven studies revealed a reduction of high/vigorous physical activity between 2.9 and 52.8%. Walking, moderate, vigorous, and total physical activity levels have been reduced during the COVID-19 pandemic confinements in university students of different countries. Despite of the reductions, those who met the current minimum PA recommendations before the lockdown generally met the recommendations also during the confinements. (shrink)

What are the conditions under which one biological object is a part of another biological object? This paper answers this question by developing a general, systematic account of biological parthood. I specify two criteria for biological parthood. Substantial Spatial Inclusionrequires biological parts to be spatially located inside or in the region that the natural boundary of t he biological whole occupies. Compositional Relevance captures the fact that a biological part engages in a biological process that must make a necessary contribution (...) to a condition that is minimally sufficient to one or more of the characteristic behaviors of the biological whole. Instead of emphasizing the diversity of part-whole relations in the biological world, this paper asks what biological part-whole relations have in common and what constrains their existence, in general. After presenting the two criteria for biological parthood I discuss in how far my account can cope with hard cases (e.g., redundant parts) and I reveal the merits and limits of monism. (shrink)

La ética ambiental, últimamente se ha visto consultada y retomada, gracias a las diferentes situaciones problemáticas respecto a los ecosistemas y a los cambios que se han dado alrededor del planeta, ya que es recurrente que cada vez sean más y frecuentes, los cambios climáticos y fenómenos naturales que antes no se daban en determinados territorios.Gran parte de las problemáticas tienen que ver con las labores que realizamos los seres humanos, si no es que toda la responsabilidad recae en nosotros, (...) con ello nos referimos a que todo el desequilibrio climático que se tiene hoy en día, es causa de la poca estima que tenemos respecto con el ambiente, la contaminación de suelo, agua y aire; que si bien se nos enseña a separar la basura de nada sirve si al final se reúne toda en los deshechos o rellenos, por otra parte la poca autorreflexión de los seres humanos en cuanto a ello, así como el daño que ello les provoca a las especies de todo tipo, llevándolas al peligro, y por último a la extinción, empero no sólo las especies animales se ven afectadas, sino también la flora de los ecosistemas va desapareciendo con la invasión del ser humano y el poco respeto a la naturaleza, cada vez las sociedades crecen más y con ello, por ende, el crecimiento de la ciudad o mancha urbana.Todo lo anterior nos remite a que se piense desde un ámbito ético, es decir, nuestra relación con el medio ambiente, por lo que nuestro objetivo es plantear las principales problemáticas acerca del tema y de la ética ambiental desde una perspectiva filosófica que, si bien ya es parte, de todo esto, nos cuestionamos: ¿qué se puede hacer respecto a la contaminación?, ¿qué se debería cambiar? ¿para qué? ¿a dónde llegar? ¿cómo lograrlo? es por ello que se tomará en cuenta el trabajo de los filósofos desde una perspectiva de la ética, para poder proponer soluciones o tratar de detener las problemáticas, para causar cambios de algunos hábitos a partir de la reflexión del individuo, es cierto que cada individuo; tiene una rutina e inconscientemente se vuelve parte de la contaminación, de todas las acciones que ejecutamos en el día usamos diferentes instrumentos que provienen de la naturaleza, y es obvio que no se puede llegar a ser un ermitaño, del bosque o del campo, estando acostumbrado a las comodidades de la ciudad, lo que se busca aquí es la reflexión de las actividades que desempeñamos todos los día y poder cambiarlas o si es posible frenarlas de algún modo (si no es necesaria la actividad dentro de la vida), para ser más amigables y responsables del planeta, ya que es éste el fin de la ética ambiental: ponerla en práctica, aplicar las teorías que sean benefactoras del medio ambiente.

How is hope to be found amid the ethical and political dilemmas of modern life? Writer and philosopher Mary Zournazi brought her questions to some of the most thoughtful intellectuals at work today. She discusses "joyful revolt" with Julia Kristeva, the idea of "the rest of the world" with Gayatri Spivak, the "art of living" with Michel Serres, the "carnival of the senses" with Michael Taussig, the relation of hope to passion and to politics with Chantal Mouffe and Ernesto Laclau. (...) A dozen stimulating minds weigh in with their visions of a better social and political order. The result is a collaboration - of writing, of thinking, and of politics - that demonstrates more clearly than any single-authored project could how ideas encountering one another can produce the vision needed for social change.

Mary Shepherd's An Essay upon the Relation of Cause and Effect, first published in 1824, was a pioneering work in metaphysics and epistemology. Together with her 1827 Essays on the Perception of an External Universe, they make her one of the most important philosophers of her era. Although widely neglected by the history of philosophy in the decades after her death, her works have recently begun to attract the attention and sustained study they deserve. In the course of her writings, (...) Shepherd offers trenchant and detailed rebuttals of the arguments and conclusions of many prominent predecessors-including George Berkeley, Thomas Reid, Dugald Stewart, Thomas Brown, William Lawrence, and especially David Hume-but she is no merely negative thinker. On the contrary, her critiques are always in the service of her own distinctive and highly original doctrines, which are of striking contemporary interest. Appearing two hundred years after its original publication, this is the first full modern edition of her first book, which presents and defends the theory of causation and scientific knowledge that constitutes the cornerstone of her entire philosophy. The edition includes an extensive introduction and scholarly notes throughout that provide historical and philosophical context while explaining the central ideas of the work. It also includes Shepherd's two essays published in 1828 and all of her known letters-all but one of them published here for the first time-which shed significant additional light on her philosophical ideas.

Anger has potential epistemic value in the way that it can facilitate a process of our coming to have knowledge and understanding regarding the issue about which we are angry. The nature of anger, however, may nevertheless be such that it ultimately undermines this very process. Common non-philosophical complaints about anger, for instance, often target the angry person as being somehow irrational, where an unformulated assumption is that her anger undermines her capacity to rationally engage with the issue about which (...) she is angry. Call this assumption the charge of emotional irrationality regarding anger. Such a charge is pernicious when levelled at the anger of those in positions of marginalisation or oppression, where it can threaten to silence voices on the very issue of the injustices that they face. In this paper I thus provide a much-needed interrogation of this charge. Firstly, and drawing on empirical literature on the effects of anger on decision-making, I flesh out the charge and why it poses a threat to how the epistemic value of anger has been defended. Secondly, I argue that the charge of emotional irrationality regarding anger can nevertheless be unwarranted, at least within a common context of political anger. (shrink)

Discussion of Wittgenstein's Tractatus is currently dominated by two opposing interpretations of the work: a metaphysical or realist reading and the 'resolute' reading of Diamond and Conant. Marie McGinn's principal aim in this book is to develop an alternative interpretative line, which rejects the idea, central to the metaphysical reading, that Wittgenstein sets out to ground the logic of our language in features of an independently constituted reality, but which allows that he aims to provide positive philosophical insights into (...) how language functions. McGinn takes as a guiding principle the idea that we should see Wittgenstein's early work as an attempt to eschew philosophical theory and to allow language itself to reveal how it functions. By this account, the aim of the work is to elucidate what language itself makes clear, namely, what is essential to its capacity to express thoughts that are true or false. However, the early Wittgenstein undertakes this descriptive project in the grip of a set of preconceptions concerning the essence of language that determine both how he conceives the problem and the approach he takes to the task of clarification. Nevertheless, the Tractatus contains philosophical insights, achieved despite his early preconceptions, that form the foundation of his later philosophy. -/- The anti-metaphysical interpretation that is presented includes a novel reading of the problematic opening sections of the Tractatus, in which the apparently metaphysical status of Wittgenstein's remarks is shown to be an illusion. The book includes a discussion of the philosophical background to the Tractatus, a comprehensive interpretation of Wittgenstein's early views of logic and language, and an interpretation of the remarks on solipsism. The final chapter is a discussion of the relation between the early and the later philosophy that articulates the fundamental shift in Wittgenstein's approach to the task of understanding how language functions and reveal the still more fundamental continuity in his conception of his philosophical task.

Agonistic Democracy explores how theoretical concepts from agonistic democracy can inform institutional design in order to mediate conflict in multicultural, pluralist societies. Drawing on the work of Foucault, Nietzsche, Schmitt, and Arendt, Marie Paxton outlines the importance of their themes of public contestation, contingency and necessary interdependency for contemporary agonistic thinkers. Paxton delineates three distinct approaches to agonistic democracy: David Owen's perfectionist agonism, Mouffe's adversarial agonism, and William Connolly and James Tully's inclusive agonism. Paxton demonstrates how each is fundamental (...) to enabling citizens to cultivate better virtues for themselves and society (Owen), motivating democratic engagement (Mouffe) and enhancing relations of respect and understanding between conflicting citizens (Connolly and Tully). Situated within the context of a deeply polarised post-Trump America and post-Brexit Britain, this book reveals the need to rethink our approach to conflict mediation through democratic institutions. Pulling together insights from experimental research with deliberative democratic innovations, Paxton explores how agonistic theory might be institutionalised further. Through discussing ways in which agonistic institutions might be developed to render democracy more virtuous, more engaging, and more inclusive, Agonistic Democracy provides a unique resource for students of contemporary political theory.

In this book, Mary Midgely turns a spotlight on the fashionable view that we no longer need or use moral judgements. She shows how the question of whether or not we can make moral judgements must inevitably affect our attitudes to the law and its institutions, but also to events that occur in our daily lives.

This paper responds to John Burgess's ‘Mathematics and _Bleak House_’. While Burgess's rejection of hermeneutic fictionalism is accepted, it is argued that his two main attacks on revolutionary fictionalism fail to meet their target. Firstly, ‘philosophical modesty’ should not prevent philosophers from questioning the truth of claims made within successful practices, provided that the utility of those practices as they stand can be explained. Secondly, Carnapian scepticism concerning the meaningfulness of _metaphysical_ existence claims has no force against a _naturalized_ version (...) of fictionalism, according to which our ordinary standards of scientific evidence may show that we have no reason to believe the mathematical existence claims made within the context of our mathematical and scientific theories.

This is the first modern edition of the works of Lady Mary Shepherd, one of the most important women philosophers of the early modern period. Shepherd has been widely neglected in the history of philosophy, but her work engaged with the dominant philosophers of the time - among them Hume, Berkeley, and Reid. In particular, her 1827 volume Essays on the Perception of an External Universe outlines a theory of causation, perception, and knowledge which Shepherd presents as an alternative to (...) what she sees as the mistaken views of Berkeley and Hume. What she ultimately presents is an original and systematic metaphysics and epistemology. Shepherd's Essays consists of two parts. The first is a theory of perception and knowledge of the external world, which is designed to rebut idealism and skepticism about the external world and show that our ordinary beliefs are based on reason. The second is a collection of essays on topics in metaphysics and epistemology, including the immateriality and eternity of the mind, the relationship between mind and body, the possibility of miracles, the association of ideas, the relationship between physical and mathematical reasoning, and the epistemology of testimony. Antonia LoLordo's edition of Shepherd's Essays includes scholarly notes throughout the text that provide historical and philosophical context and expand on the major concepts of Shepherd's system. Her extensive introduction to Shepherd's life and works surveys some of the major points of Shepherd's system, points out directions for future research, and offers guidance for readers planning to teach her work in their courses. This volume is an invaluable primary resource for scholars, graduate students, and undergraduates interested in metaphysics, epistemology, and early modern philosophy. (shrink)

The chapter furthermore highlights the role of the (...) Baconian system of the sciences in the acceptance of Isaac Newton's Principia mathematica. (shrink)

«Claros del bosque» es uno de los libros esenciales de la trayectoria filosófica de María Zambrano en el que vemos, por primera vez, en marcha su «razón poética». Nadie mejor que la propia autora para presentarnos el significado de esta obra: “«Claros del bosque» dentro de mi pensamiento vertido en lo impreso, salvo alguna excepción, aparece como algo inédito salido de ese escribir irreprimible que brota por sí mismo y que ha ido a parar a cuadernos y hojas que nadie (...) conoce, ni yo misma, reacia que soy a releerme. Tenía que suceder por fuerza. Mas creo que el carácter de ofrenda de «Claros del bosque» a la persona a quien va dedicado en su tránsito tiene que ver en ello, acentuando así el carácter de ofrenda que todo lo que he publicado tiene desde siempre. Nada es de extrañar que la razón discursiva apenas aparezca. Con anterioridad esbocé una ‘Crítica de la razón discursiva’ que no podría prometerme que salga de ese estado. Creo, pues, que como libro es el que más responde a esa ‘idea’ hace tiempo formulada de que ‘pensar es ante todo –como raíz, como acto–– descifrar lo que se siente’, entendiendo por sentir el ‘sentir originario’, expresión usada por mí desde hace años. Y también que ‘el hombre es el ser que padece su propia trascendencia’ en un incesante proceso de unificación entre pasividad y conocimiento, entre ser y vida. Vida verdadera, sorprendida tan sólo en algunos claros que se abren en la espesura inicial entre cielo y tierra. Y en el remoto horizonte donde cielo y tierra, ser y vida, vida y muerte se anegan”.

Lower extremity non-contact soft tissue injuries are prevalent in elite futsal. The purpose of this study was to develop robust screening models based on pre-season measures obtained from questionnaires and field-based tests to prospectively predict LE-ST injuries after having applied a range of supervised Machine Learning techniques. One hundred and thirty-nine elite futsal players underwent a pre-season screening evaluation that included individual characteristics; measures related to sleep quality, athlete burnout, psychological characteristics related to sport performance and self-reported perception of chronic (...) ankle instability. A number of neuromuscular performance measures obtained through three field-based tests [isometric hip strength, dynamic postural control and lower extremity joints range of motion ] were also recorded. Injury incidence was monitored over one competitive season. There were 25 LE-ST injuries. Only those groups of measures from two of the field-based tests, as independent data sets, were able to build robust models [area under the receiver operating characteristic curve score ≥0.7] to identify elite futsal players at risk of sustaining a LE-ST injury. Unlike the measures obtained from the five questionnaires selected, the neuromuscular performance measures did build robust prediction models. The inclusion in the same data set of the measures recorded from all the questionnaires and field-based tests did not result in models with significantly higher performance scores. The model generated by the UnderBagging technique with a cost-sensitive SMO as the base classifier and using only four ROM measures reported the best prediction performance scores. The models developed might help coaches, physical trainers and medical practitioners in the decision-making process for injury prevention in futsal. (shrink)

How do we act justly in the world? How can we ethically respond to social and economic crisis and the desperation caused by violence and atrocity? Justice and Love is a philosophical dialogue on how to imagine and act in a more just world by theologian Rowan Williams and philosopher Mary Zournazi. Drawing on examples from the European Migrant Crisis to Brexit, the authors reflect on justice as a condition of being rather than cold fact. Looking at different religious and (...) philosophical traditions to enrich our language of justice, this book explores the love and patience needed for social healing and the imagination required to experience the world in new ways.

En este libro, la autora desarrolla su concepción del juicio reflexionante inspirada en Emmanuel Kant y en Hannah Arendt para concentrarse en cómo cierto tipo de narraciones modelan nuestras nociones de lo que consideramos moral. Lara nos ofrece distintas concepciones sobre el mal en su formulación histórica mediante los ejemplos de las tragedias griegas, las diferentes concepciones sobre el mal en la obra de Shakespeare, el uso literario de la metáfora en la obra de Joseph Conrad y en narraciones fílmicas (...) que describen la crueldad humana. Lara sugiere que el aprendizaje moral es un proceso en el que intervienen las instituciones sociales, la voluntad de los individuos y de las sociedades para comprometerse a un debate abierto y con ello modelar los juicios colectivos sobre el pasado. Lara enfatiza que el juicio reflexionante se da entre un evento, una narración de dicho evento y la recepción pública de dicha narrativa. En este libro se aportan importantes métodos para la comprensión del fenómeno moral del mal, porque introducen nuevas verdades desvelatorias acerca de eventos particulares que no pueden ser simplemente captados por medio de categorías conceptuales. Lara utiliza como fuentes a Jürgen Habermas, Walter Benjamin, Primo Levi, Giorgio Agamben y Ariel Dorfman para probar la conclusión de este tipo de narraciones: la acción (de crueldad) ata de manera definitiva al perpetrador con su víctima.

In Vodou Cosmology and the Haitian Revolution in the Enlightenment Ideals of Kant and Hegel, Vivaldi Jean-Marie begins with an interpretation of the rise of Vodou practices in Saint-Domingue which is sensitive to the social, spiritual and cultural challenges of the slaves communities in Saint-Domingue, later Haiti. He shows effectively that Vodou cosmology emerged as a spiritual, social and cultural technology for the enslaved to overcome the dissonance and brutality of slavery in Saint-Domingue. Vodou Cosmology thus assumes the tripartite (...) role of spiritual, social and cultural compass for slaves who, concurrently with the development of Vodou, managed to establish a common ethos. Furthermore, to situate the rise of Vodou cosmology within the larger discourse of the Enlightenment and argue that it heralded a radical Enlightenment in the African diaspora, Jean-Marie compares and contrasts some aspects of the philosophies of Kant and Hegel with the social, spiritual and cultural experience of the enslaved communities of Saint-Domingue. This comparison shows that Kant and Hegel's depiction of African Negroes' mores and their religious practices in the colonies fails to capture that Vodou cosmology was both a mechanism of resistance and the medium to restore their social, spiritual, and cultural identity against the backdrop of the Atlantic slave trade. Also, he elaborates the Enlightenment's conception of African Negroes as commercial currency and specifically Hegel's view of slavery in the colonies as the manifestation of divine providence. He concludes that the significance of the Haitian Revolution lies in the fact that it ascribed freedom to people of African descent in the diaspora and is thus implicit in later themes of black freedom. The Haitian Revolution ties blackness with freedom and mapped out a radical enlightenment in the European colonies. (shrink)

In this paper we discuss the meaning of Owen's coalitional extension of the Banzhaf index in the context of voting situations. It is discussed the possibility of accommodating this index within the following model: in order to evaluate the likelihood of a voter to be crucial in making a decision by means of a voting rule a second input (apart from the rule itself) is necessary: an estimate of the probability of different vote configurations. It is shown how Owen's coalitional (...) extension can be seen as three different normative variations of this model. (shrink)

Derrida and the Future of the Liberal Arts highlights the Derridean assertion that the university must exist 'without condition' - as a bastion of intellectual freedom and oppositional activity whose job it is to question mainstream society. Derrida argued that only if the life of the mind is kept free from excessive corporate influence and political control can we be certain that the basic tenets of democracy are being respected within the very societies that claim to defend democratic principles. This (...) collection contains eleven essays drawn from international scholars working in both the humanities and social sciences, and makes a well-grounded and comprehensive case for the importance of Derridean thought within the liberal arts today. Written by specialists in the fields of philosophy, literature, history, sociology, geography, political science, animal studies, and gender studies, each essay traces deconstruction's contribution to their discipline, explaining how it helps keep alive the 'unconditional', contrapuntal mission of the university. The book offers a forceful and persuasive corrective to the current assault on the liberal arts. (shrink)

This collection is the first comprehensive history of Fichte's reception in America, highlighting the existence of a long and strong tradition of Fichtean studies throughout the continent and demonstrating the centrality of Fichtean ideas in contemporary discussions of issues such as feminism, social criticism, and decolonial thought. Read and reinterpreted in the highly diverse circumstances across the American continent, Fichte's ideas are presented in a radically new light, uncovering the Fichtean spirit of self-activity and autonomous thought in an American context.

La renommée nationale et internationale de Pierre Bourdieu lui est venue de la sociologie, une sociologie un peu particulière, dite " des élites ", ou plus communément, " de la domination ", au fil de laquelle il ne se fit pas faute de fustiger les représentants de celle qu'il appelait " La discipline du couronnement ", la philosophie. C'était là pourtant son terroir d'origine, sa formation première, et la seule dans laquelle il possédât un diplôme. Mais il ne voyait dans (...) ses anciens " collègues " que des lectors figés dans une position scolastique qui les éloignait des urgences du monde et du " sens pratique ". Pourtant, c'est à l'aide de La philosophie qu'il critique la philosophie, et vise à l'éduquer, qu'il forge les concepts majeurs de sa sociologie, comme l'habitus, la violence symbolique. Et l'enjeu de ses recherches est encore un enjeu philosophique, qui le rapproche de ceux qui ont voulu transformer le monde, au lieu de se borner à le penser. (shrink)
