Engagement in marine science has historically been the privilege of a small number of people with access to higher education, specialised equipment and research funding. Such constraints have often limited public engagement and may have slowed the uptake of ocean science into environmental policy. Recognition of this disconnect has spurred a growing movement to promote ocean literacy, defined as one’s individual understanding of how the ocean affects people and how people affect the ocean. Over the last 2 decades, this concept (...) has gained significant traction in marine biology and environmental education circles and now plays a prominent role in the UN’s Decade of Ocean Science for Sustainable Development. Here, we argue that the ocean literacy agenda has largely been shaped and discussed by marine scientists and educators but needs to be expanded to a much larger constituency to be more effective, accessible and inclusive. We discuss diverse cultural settings from around the world and provide examples of indigenous, spiritual, art, ocean user and other groups that are already deeply engaged with the ocean and could provide a variety of perspectives to enrich the ocean literacy concept beyond an understanding of marine science. We suggest that such inclusiveness could remove the historic barriers that have surrounded the field, transform our collective awareness of and relationship with the ocean and help support ongoing efforts to restore marine biodiversity.

En este trabajo se describe un nuevo dispositivo didáctico que estamos diseñando y completando, los Recorridos de Estudio e Investigación (REI), que quieren contribuir a crear secuencias de enseñanza-aprendizaje.

Le 15 décembre 2001, le Conseil européen de Laeken a adopté l'ambitieuse 'Déclaration sur l'Avenir de l'Europe'. A travers une série de questions fondamentales relatives à l'avenir de l'Union européenne, elle entame un débat qui se concentre principalement autour de la répartition des compétences entre l'Union et les Etats membres, la simplification des instruments d'action de l'Union, son architecture institutionnelle et la voie vers une Constitution pour les citoyens européens. En annexe figure un essai de répartition sous forme «d'arbre thématique» (...) de toutes les questions évoquées par cette «Déclaration de Laeken». (shrink)

Ontologies are being used by information scientists in order to facilitate the sharing of meaningful information. However, computational ontologies are problematic in that they often decontextualize information. The semantic content of information is dependent upon the context in which it exists and the experience through which it emerges. For true semantic interoperability to occur among diverse information systems, within or across domains, information must remain contextualized. In order to bring more context to computational ontologies, we introduce culture as an essential (...) concept for information science. Culture helps to focus our attention on and make meaning of relevant extrapersonal structures and their qualities and dimensions that comprise the context and background of the world. In our approach, culture is integral to the study of semantics and, consequently, the study of ontologies and information technologies. The meaning we make of entities and phenomena in the world is always shaped by our cultural experience. If we understand culture as the emergent interplay of intrapersonal cognitive structures and extrapersonal structures of the world, then the notion of cognitive and cultural schemas becomes essential to understanding ontology and the ways in which we might achieve authentic semantic interoperability among diverse information systems. We explore the nature of ontologies and reconceptualize them as cultural schemas. Our proposal is an alternative to the historical path from philosophical ontology to computational ontologies as one that adheres primarily to the notion of ontology as a categorization and classification system. The obvious implication for ontology as categorization is that there is a single objective world that exists and that it can be described as entirely separate from the person observing it. We draw upon Heidegger’s examination of ontology to ground ontology in a phenomenological perspective, enabling it to remain flexible and adaptable and to accommodate context. (shrink)

We discuss the concepts of Weyl and Riemann frames in the context of metric theories of gravity and state the fact that they are completely equivalent as far as geodesic motion is concerned. We apply this result to conformally flat spacetimes and show that a new picture arises when a Riemannian spacetime is taken by means of geometrical gauge transformations into a Minkowskian flat spacetime. We find out that in the Weyl frame gravity is described by a scalar field. We (...) give some examples of how conformally flat spacetime configurations look when viewed from the standpoint of a Weyl frame. We show that in the non-relativistic and weak field regime the Weyl scalar field may be identified with the Newtonian gravitational potential. We suggest an equation for the scalar field by varying the Einstein-Hilbert action restricted to the class of conformally-flat spacetimes. We revisit Einstein and Fokker’s interpretation of Nordström scalar gravity theory and draw an analogy between this approach and the Weyl gauge formalism. We briefly take a look at two-dimensional gravity as viewed in the Weyl frame and address the question of quantizing a conformally flat spacetime by going to the Weyl frame. (shrink)

O texto a seguir, intitulado “Ensaio Histórico sobre a Cavalaria e a Honra dos Modernos”, foi escrito durante a juventude de David Hume, certamente antes da publicação do Tratado da Natureza Humana. Ainda não há consenso inabalável sobre o ano em que esse ensaio foi produzido. John Hill Burton, que o publicou pela primeira vez, em 1846, considera que Hume o teria escrito em 1727, logo após deixar o Edimburgh College. J. Y. T. Greig propõe uma conjectura um pouco mais, (...) por assim dizer, elástica, considerando que o texto deve ter sido escrito no período de 1729 a 1734. (shrink)

Apresentam-se os resultados clínicos principais de uma primeira investigação efectuada a familiares de doentes sob tratamento paliativo no domicílio da área de Lisboa, com o instrumento de medida da satisfação SERVQUAL Modificado. Dos 58 familiares/doentes que responderam ao questionário apenas uma minona estava insatisfeita (uma classe de 5 indivíduos mostra-se francamente insatisfeita), uma classe de 15 estava moderadamente satisfeita, havendo 38 individuos fortemente satisfeitos com a qualidade e prontidäo dos serviços prestados. Porém urna percentagem elevada de doentes, segundo a opinião (...) retrospectiva dos cuidadores, faleceu com sintomatologia agravada, nomeadamente dores (60%), obstipação (67%) e depressão/ansiedade (43%). Discute-se a consistência e validade do questionáno SERVQUAL Modificado, contextualizam-se os resultados no que é o standard da prática da MCP e integram-se na promoção da dignidade humana no fim da vida. We present the main clinical findings of research on palliative home care, carried out among relatives of patients in the Lisbon area. An adapted version of SERVQUAL was used. Of a total of 58 carers surveyed only a small number (5) was unsatisfied 15 were only moderately satisfied. 38 family carers were strongly satisfied with the services. Yet, a high percentage of patients, as viewed in retrospect by their relatives died with some aggravated symptoms: 60% with more pain, 67% constipation, and 43% anxiety/depression. We discuss the consistency and validity of this adapted SERVQUAL tool and the main results are contextualized beanng in mind the standard practice of palliative medicine and the pursuit of human dignity in death.

The Leslie matrix model for discrete population growth has been modified and used several times in population dynamics. A review is given of the basic model and of its principal modifications. The modifications relating to the influences of ‘internal’ or ‘external’ factors to the population are studied with greater detail. The same applies to models where the population is divided in stages rather than in age classes. In the same line, Hadjibiros studied a more general model, where the transition matrix (...) corresponds to a population divided in stages of unequal duration, and where the time varying influences of the ‘internal’ or ‘external’ factors are included. This model offers the possibility of computer simulation of the population dynamics of a natural population represented by a demographic vector. Some kind of relationship is proposed between the general matrix model and the Lefkovitch matrix ; the elements of which, obtained by regression techniques from census data, describe the biological dependance of a stage i at time t + 1 on a stage j at time t.

O trabalho analisa as relações entre discurso_ _e ser estabelecidas de forma dialética por Platão em seu diálogo tardio _Sofista_. Os sofistas defendiam a impossibilidade de provar a falsidade ou veracidade dos discursos. Tais pensadores baseavam-se no interdito ontológico de Parmênides de Eleia, que preconizava, em linhas gerais, a existência de uma estrita correspondência entre tudo que pode ser dito e o ser, de forma que seria, assim, impossível, dizer algo que não é, ou seja, um não-ser. Contrariando tal perspectiva (...) e fazendo uso do método da _diaíresis _– em que os seres são caracterizados por suas diferenças mais fundamentais –, o _Sofista _se desenrola revisitando e revisando as teorias ontológicas de seu tempo, a fim de explorar uma nova forma de pensar a relação entre os seres. Platão assegura, com isso, a possibilidade de análise qualitativa do discurso predicativo e define, consequentemente, o erro como desarmonia entre o dizer e o ser. Para tamanha empreitada, o filósofo explica como se dá o entrelaçamento na relação de ser e não-ser, relação mediada pelas seguintes categorias fundamentais: ser, mesmo, outro, movimento e repouso. A partir disso, a dialética é finalmente constituída como a técnica correta de diferenciação entre os predicados possíveis de comunicação com cada sujeito. Graças aos resultados filosóficos dessa empreitada, iniciaram-se as reflexões que levaram Aristóteles a instrumentalizar as análises da linguagem. (shrink)

No presente artigo, defendemos que uma constelação é formada por gêneros que se diferenciam em seus propósitos comunicativos específicos, mas que podem ser agrupados por razões diversas, como para a realização de uma tarefa para a qual seja necessária uma cadeia de gêneros. (SWALES, 2004). Com base na perspectiva teórica acima, objetivamos discutir as implicações pedagógicas do conceito de constelação de gêneros, tomando como referência o ensino da língua materna. Acreditamos que a compreensão do citado fenômeno, por parte dos professores, (...) pode ser útil para este ensino na medida em que a competência sociodiscursiva dos alunos pode ser ampliada em relação a um determinado elemento motivador da constelação. Isto se justifica porque os gêneros que se constelam se tornam distintos entre si graças à teia de propósitos comunicativos que eles formam dentro da constelação, a fim de atender às mais diversas funções sociais dentro da tarefa maior em função da qual eles se encadeiam. Portanto, o estudo de cadeia de gêneros dentro de uma tarefa escolar maior pode proporcionar aos estudantes uma visão mais ampla da função social dos gêneros, não limitando a compreensão acerca dos modos como a sociedade organiza seus processos comunicativos nos diversos tipos de constelação que podem existir.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Descartes’s Dualism by Marleen RozemondSteven J. WagnerMarleen Rozemond. Descartes’s Dualism. Cambridge: Harvard University Press, 1998. Pp. xx + 279. Cloth, $24.00.Rozemond gives particular attention to questions of mind-body distinctness vs. union and to the status of sensory ideas. Her historical emphasis, backed by impressive scholarship, is Descartes’s relation to the late scholastics. Rozemond is clear, alert to detail, and fair-minded. While the text is too long (esp. in (...) chapters 4–5), this study is indeed rich, its scope and architecture justified.Any good reading of a philosopher is defined—both enhanced and limited—by certain decisions. I have mentioned one of Rozemond’s: her account of Descartes’s dialogue with such predecessors as Suárez and Fonseca sheds important light. It makes one ask, further, whether standard histories are not just as wrong to ignore scholastic concerns in, say, Hobbes, Spinoza, and Locke. Yet Rozemond is less helpful with issues that make more sense when we read forward from the 1640s, not back. An historian also sets a level of philosophical engagement. One chooses between presenting a meaningful narrative, and struggling with the endless problems of detail that can both doom [End Page 678] a philosophical position and give it life. Rozemond inclines toward narrative, often stopping just short of hard questions. Yet she shows curiosity and intelligence throughout. As in the first case, another decision would not have been better or worse but simply yielded a different kind of history.Fundamental is a third choice. A philosopher’s thought may appear as an orderly structure; or as a mix of fixed points and shifting, inconsistent tendencies. Most of us are trained to the former style of representation (although we let philosophers “develop” over time). Rozemond’s Descartes, too, turns out this way. He occupies definite positions. Within each position he knows whether Ρ is a premise for Q, vice versa, or neither. This way of presenting a body of thought, i.e., as a determinate structure admitting logical assessment, is an indispensable tool for historians. Its value in any particular case is, however, a matter of judgment. Rozemond attacks textual problems with skill, often improving decisively on the competition, but the going looks smoother than it is. Sometimes she carries the privilege of selective reading too far. At other times, she overlooks the poor mutual fit of separately smooth solutions, or rests with an outcome that could not have satisfied Descartes. Some examples:1. There is an old question how far Descartes goes towards proving dualism in the Second Meditation, how much is left for the Sixth. Rozemond basically champions the Second Meditation. Although some texts favor this, she ignores important contrary passages. Her reconstruction of the “argument from separability” also fails completely to carry over to Descartes’s alternate proof (AT VII, 85–6) from the indivisibility of mind.2. Rozemond identifies (“pure”) intellection with thought or mind (56). This leaves a problem how sensation could be a mode of thought, given that for her sensations differ from pure thoughts in being ‘modes of the mind as united to the body’ (201, emphasis mine). She remarks that sensations are not ‘straightforward modes of the mind’; yet her earlier chapters have no place for obscure modal hybrids and indeed require the tidy metaphysical scheme that is now denied.3. Although Rozemond handles Descartes’s anti-empiricism well, the discussion of empty space (95–7) no sooner suggests than it drops a crucial question. Descartes traces belief in the void to a childhood prejudice according to which all bodies are perceptible; rejecting the prejudice is supposed to remove support for the hypothesis of the void. But can Descartes really pick up the doctrine of childhood prejudice, an anti-Aristotelian weapon, and turn it against the radically different atomist framework? Rozemond passes on the attendant philosophical and textual problems (cf. 133–7).4. Rozemond’s extensive treatment of sensory perceptions and qualities rewards study (particularly on the importance, for dualism, of problems about body). But she misses the chance for more. Her Descartes firmly “places sensory qualities in the mind.” The real one struggled repeatedly over whether sensory ideas can or must... (shrink)

This paper examines the thinking of Bernard of Clairvaux about love in relationship to the ideas of his two famous contemporaries, Peter Abelard and Héloise. It looks at Bernard's intellectual debt to William of Champeaux on issues of sin and grace, and to William of Saint-Thierry for ideas about how amor evolves into caritas. Bernard makes a stronger link between amor and dilectio, and introduces use of the Song of Songs, to explain how worldly love can develop into spiritual love. (...) The author also considers the evolution of the ideas about love of Peter Abelard, observing that he draws on the same definition of Cicero in the Sic et Non and Theologia as underpins a rather crude attempt to define love in the Epistolae duorum amantium, which the author of the article thinks to be a record of the early letters of Abelard and Héloise. Whereas Abelard always contrasts worldly and spiritual love, the effort of Heloise to connect amor and dilectio parallels that of Bernard. /// O presente artigo debruça-se sobre o pensamento de S. Bernardo de Claraval acerca do amor em relação com as ideias desenvolvidas pelos seus dois famosos contemporâneos, Pedro Abelardo e Heloísa. Além disso, o artigo toma também em consideração a dívida intelectual de S. Bernardo em relação a Guilherme de Champeaux a propósito de temas como o pecado e a graça, bem como a Guilherme de Saint-Thierry relativamente a ideias acerca de como amor se transforma em caritas. Bernardo estabelece um vínculo forte entre amor e dilectio, e introduz o uso do Cântico dos Cânticos para explicar de que modo o amor mundano se pode transformar em amor espiritual. O artigo toma também em considerçãdo a evolução das ideias acerca do amor de Pedro Abelardo, referindo o facto de que ele se inspira na definição do Cicero no Sic et Non e Theologia, sublinhando a sua tentativa de definição do amor nas Epistolae duorum amantium, as quais são aqui consideradas como um arquivo das primeiras cartas entre Abelardo e Heloísa. Finalmente, o artigo chama também a atenção para o facto de que Abelardo tende a contrasrar o amor mundano e o amor espiritual, ao passo que o esforço de Heloísa em conectar amor e dilectio paralela o próprio esforço de S. Bernardo. (shrink)

Autor de vasta e rigorosa obra de investigação histórico-filosófica, Domingos Maurício participou no corpo incial dos redactores da. Revista Portuguesa de Filosofia, cabendo-lhe a autoria do texto programático de abertura da publicação, em 1945.

A única via possível para realizar esse vasto programa foi a da objectividade da investigação histórica, da erudição verdadeiramente rigorosa, da crítica exigente. A realização destes objectivos constitui, a nosso ver, o grande merito historiográfico de Domingos Maurício, e isso lhe conquistou um lugar ímpar na História da Filosofia e na História das Ideias em Portugal. /// Auteur d'une vaste et rigoureux travail de recherche histoire-philosophique, Domingos Maurício étail menibre du groupe initial des redacteurs de la Revista Portuguesa de Filosofia, et fut l'auteur du texle-programme lors de l'apparilion de la publication en 1945.

The definition of acedia presents unique conceptual problems among the eight Evagrian logismoi. Its descriptions are so complex and varied as to render the concept seemingly incoherent. This article argues that the conceptual unity of acedia has been obscured by the translation of Evagrian logismoi into the ‘deadly sins’ tradition, resulting in a category error. Acedia is more properly understood, not as a psychological state or a sin, but rather as an array of demonic temptations with the unifying end-goal of (...) interrupting the anchoritic ideal of sustained contemplation.

Part intellectual autobiography and part exposition of complex yet contemporary economic ideas, this lively conversation with renowned scholar and public intellectual Kenneth J. Arrow focuses on economics and politics in light of history, current events, and philosophy as well. Reminding readers that economics is about redistribution and thus about how we treat each other, Arrow shows that the intersection of economics and ethics is of concern not just to economists but for the public more broadly. With a foreword by Amartya (...) Sen, this book highlights the belief that government can be a powerful force for good, and is particularly relevant in the current political climate and to the lay reader as well as the economist.

It would be a mistake to attempt to identify in modern terms the disease of Galerius described so graphically by Lactantius, Mort. 33. Consumption by lice or worms, if not genital ‘gangrene’, was a typical end for a tyrant or the impious, and there must be an element of literary exaggeration in Lactantius' account. But whatever one makes of the nature of the illness, Lactantius did set out to give the passage a scientific plausibility by his use of technical medical (...) phraseology, and by an allusion to a medical theory at 33.7. Recognition of this theory allows one to settle the text at one point, where editors have failed to agree. There is also a second place in the chapter where familiarity with medical Latin points one towards the solution of a textual problem. (shrink)

The demonstration by E. Wölfflin that between theHistoriesandAnnalsTacitus progressed towards a more archaic and artificial style is well known. From the outset Tacitus adhered to the traditional Roman view that history should be composed in an archaic language remote from everyday usage ; but he was apparently at first not fully aware of the possibilities of the archaizing style. New archaisms and artificial usages suggested themselves as he advanced ; and others, which he had used sporadically even early in theHistories, (...) were allowed to oust ordinary alternatives completely.

Takeuti introduced an infinitary proof system for determinate logic and showed that for transitive models of Zermelo-Fraenkel set theory with the Axiom of Dependent Choice that contain all reals, the cut-elimination theorem is equivalent to the Axiom of Determinacy, and in particular contradicts the Axiom of Choice. We consider variants of Takeuti's theorem without assuming the failure of the Axiom of Choice. For instance, we show that if one removes atomic formulae of infinite arity from the language of Takeuti's proof (...) system, then cut elimination is equivalent to a determinacy hypothesis provable, e.g., in ZFC + “there are infinitely many Woodin cardinals.” A slight extension of the proof system admits cut elimination for countable sequents under the same assumptions. A simple modification of the proof system yields analogs of the results above for the Axiom of Real Determinacy and uncountably many Woodin cardinals. (shrink)

This essay answers the question: Which are the themes often considered as “Philosophy of Law” that are of concern to legal scholars? My answer seeks to sort out how the “thematic content” has become into what today is known as “Philosophy of Law” to legal scholars (against “Philosophy of Law” to philosophers).

This essay subjects to criticism the historical and philosophical attitudes to political thought found in the writings of John Dunn and Michael Oakeshott. The essay does not limit itself to criticism but attempts to elaborate what is indicated by criticism for the sake of the modern understanding of political thought. The argument is that history and philosophy as they have recently been practised suffer from limitations that can only be addressed by a recognition of something which is here called theology. (...) The significance of such a recognition is considered with regard to the history of political thought, political philosophy and finally to theology itself. The emphasis on theology makes it necessary to say that the essay is written for the benefit of historians and philosophers, not theologians. Although it is an argument for theology it is in no sense an argument from theology. Whether this is a contradictory position may require consideration elsewhere; but since the essay is a first step rather than a final step in an argument, it may gain more than it loses by such a contradiction, if there is one.
