In this paper we present a new framework of idealization in biology. We characterize idealizations as a network of counterfactual and hypothetical conditionals that can exhibit different “degrees of contingency”. We use this idea to say that, in departing more or less from the actual world, idealizations can serve numerous epistemic, methodological or heuristic purposes within scientific research. We defend that, in part, this structure explains why idealizations, despite being deformations of reality, are so successful in scientific practice. For illustrative (...) purposes, we provide an example from population genetics, the Wright-Fisher Model. (shrink)
Neste artigo, submetendo a breve análise a digressáo sobre a maiêutica “socrática”, tentamos demonstrar em que medida a escolha dos personagens do Teeteto de Platáo determina a natureza do debate desenvolvido ali. Inspirados pelo critério hermenêutico da escola de Tübingen-Miláo , julgamos que a recomposiçáo dos perfis dramático-biográficos daqueles personagens, em plena harmonia com a teoria do escrito-jogo de Platáo apresentada na parte conclusiva do Fedro e completada, em seu aspecto dramático-compositivo pelo livro III da República , seja elemento central (...) para um correto ajuste de perspectiva a partir da qual deve-se ler o diálogo. Nesta sede, recorremos também a alguns passos do tratado matemático exposto no VII livro da República de Platáo, texto fundamental para a reconstruçáo dramática dos personagens do Teeteto e, por via de consequência, para uma correta justificaçáo da leitura que propomos.

Xavier Zubiri entiende que el tema del mundo, a pesar de tener una noble prosapia en la historia de la filosofía, ha sido desatendido por la mayor parte del pensamiento reciente. Posiblemente fue Descartes el último gran filósofo en escribir un tratado dedicado temáticamente al problema del mundo. Es como si la atención a las cosas que hay en el universo hubiera hecho que se perdiera de vista el problema del universo mismo. Por supuesto, no faltan filósofos contemporáneos que (...) hayan hablado del mundo. Pero Zubiri entiende que esos filósofos lo han hecho de una manera unilateral, atendiendo únicamente al diálogo con las ciencias humanas, y desarrollando de esta manera conceptos del mundo en los que no caben las aportaciones de las ciencias naturales. Ahora bien, ya en el año 1960 Zubiri señalaba que no sólo la historia humana, sino también los nuevos descubrimientos en ciencias tales como la astronomía o la biología exigían que la filosofía se volviera a enfrentar sistemáticamente con la cuestión filosófica del mundo. Esto es lo que Zubiri hizo en este curso, impartido en la Cámara de Comercio de Madrid, y que ahora presentamos a los lectores. Sin duda, el medio siglo transcurrido desde entonces haría necesaria una actualización de las informaciones científicas que Zubiri manejaba. Sin embargo, muchos de los conceptos desarrollados por él en aquellas lecciones, precisamente por su novedad, por su radicalidad, y por su apertura a una concepción abierta y dinámica de la ciencia, siguen siendo relevantes en el presente. No sólo eso. En una última y extensa lección Zubiri se planteó una cuestión crucial para la filosofía: la de un posible fundamento del mundo. También aquí su profundo conocimiento de la historia del pensamiento, su rigor y al mismo tiempo su originalidad filosófica, siguen siendo inspiradores para los lectores contemporáneos. (shrink)

Although irrationality always presupposes rationality, I think there are good arguments to claim that sometimes rationality presupposes irrationality.This paper tries to show how irrational action can support rationality in two ways: it can develop and preserve rationality. I also argue that sometimes the development and the conservation of rationality can only be realized by irrational action.
We prove strong completeness of the □-version and the ◊-version of a Gödel modal logic based on Kripke models where propositions at each world and the accessibility relation are both infinitely valued in the standard Gödel algebra [0,1]. Some asymmetries are revealed: validity in the first logic is reducible to the class of frames having two-valued accessibility relation and this logic does not enjoy the finite model property, while validity in the second logic requires truly fuzzy accessibility relations and this (...) logic has the finite model property. Analogues of the classical modal systems D, T, S4 and S5 are considered also, and the completeness results are extended to languages enriched with a discrete well ordered set of truth constants.

In entire regions of the developing world, low physician density exacerbates child and maternal mortality and hinders treatment of HIV/AIDS. This article invites philosophers (...) to help identify ethical and effective responses to medical brain drain. It reviews existing proposals and their limitations. It makes a case that, in resource-poor countries, ‘locally relevant medical training’—teaching primarily locally endemic diseases and practice in scarcity conditions, training in rural communities and admitting rural students preferentially—could help improve retention. Locally relevant training would arguably diminish medical brain drain in five ways. It would (i) make graduates less attractive for Western employers, (ii) align graduates’ expectations with actual practice, diminishing ‘burn-out’, (iii) enhance the professional prestige of local practice, (iv) hold rotations in, and recruit applicants from, rural areas, which is known to improve retention there, and (v) create local career development options that attract practitioners to stay. Such educational reform may raise worries about poor-quality care, breach of the freedom of education and occupation, breach of the freedom of movement, unequal distribution of opportunities among students, hypocrisy and resistance from influential actors. We address these worries. CiteULike Connotea Del.icio.us What's this? (shrink)
In this article we defend the inferential view of scientific models and idealisation. Models are seen as “inferential prostheses” (instruments for surrogative reasoning) construed by means of an idealisation-concretisation process, which we essentially understand as a kind of counterfactual deformation procedure (also analysed in inferential terms). The value of scientific representation is understood in terms not only of the success of the inferential outcomes arrived at with its help, but also of the heuristic power of representation and their capacity to (...) correct and improve our models. This provides us with an argument against Sugden’s account of credible models: the likelihood or realisticness (their “credibility”) is not always a good measure of their acceptability. As opposed to “credibility” we propose the notion of “enlightening”, which is the capacity of giving us understanding in the sense of an inferential ability. (shrink)
The Arabic tradition knew Alexander’s treatises On Fate and On Providence. Alexander criticizes the Stoic determinism with some peripatetic arguments. In those treatises we can find, at least, two positions: the peripatetic and “libertarian” position represented by Alexander, and Stoic determinism. A very similar discussion can be found in Islamic tradition. As S. Van den Bergh has insisted, Islamic theological schools had some Stoic influences. One of the issues in which we can find some common views is, precisely, the problem (...) of determinism and free will. The aim of this paper is to show that the kasb (acquisition)doctrine of the Islamic theologians Asharites is very similar to Stoic determinism in its compatibilist version: both, Stoics and Asharites, conceive a causal network established by the fate or the providence. From this point of view we have to discuss which is the true agent of the natural and human acts that happen in this world. If the providence guides every act, the natural causality and the free will should be denied. On the one hand, I will present some arguments from the most representative Asharite theologian, al-Ghazali, to support a kind of compatibilist determinism; from the other hand, I will evaluate Averroes peripatetic arguments against determinism. Is Averroes more consistent than Alexander or do we have to conclude that al-Ghazali and the Asharites have stronger arguments in order to support the kasb doctrine? (shrink)

The paper considers whether public health considerations can help justify some of these rights, and explores some constraints on the justificatory force of public health (...) considerations. I outline two arguments about the moral grounds for states’ rights with regard to public health. The principle of fairness emphasizes that those who benefit from public health measures ought to contribute their fair share in upholding them. Alternatively, states’ rights might be justified by a natural duty of justice to uphold and not to obstruct institutions implementing public health policies. I indicate some reasons for preferring the latter justification. I further argue that the assignment of some rights to states via public health-based justification is undermined on several counts. Domestic political institutions cannot effectively perform some of their functions in protecting public health. Furthermore, transborder public health threats pose collective action problems at the global level. Finally, concerns about human rights work against the assignment of some rights to states. I conclude by arguing that these concerns call for global coordination, and that some rights claimed by states ought instead to be assigned to global institutions.

An extensions by new axioms and rules of an algebraizable logic in the sense of Blok and Pigozzi is not necessarily algebraizable if it involves new connective symbols, or it may be algebraizable in an essentially different way than the original logic. However, extension whose axioms and rules define implicitly the new connectives are algebraizable, via the same equivalence formulas and defining equations of the original logic, by enriched algebras of its equivalente quasivariety semantics. For certain strongly algebraizable logics, all (...) connectives defined implicitly by axiomatic extensions of the logic are explicitly definable. (shrink)
After a brief comparison of Aliseda’s account with different approaches to abductive reasoning, I relate abduction, as studied by Aliseda, to idealization, a notion which also occupies a very important role in scientific change, as well as to different ways of dealing with the growth of scientific knowledge understood as a particular kind of non-monotonic process. A particularly interesting kind of abductive reasoning could be that of finding an appropriate concretization case for a theory, originally revealed as extraordinarily success-ful but (...) later discovered to be strictly false or only approximately or ideally true. I try to show this with the example of the Kepler-Newton relation. At the end of the paper, I give criteria in order to construe abduc-tive explanations in correspondence with a reasonable account of empirical progress. (shrink)

The present paper is about the author’s current research on children’s education in urban contexts. It departs from the rising offer of programmes for school children in out-of-school contexts (e.g. museums, libraries, science centres). It asks what makes these practices educational (and not just interesting, entertaining and/or audience building). Based on Biesta ( 2006a , 2010 ) theory of education, the author frames and analyses the educational characteristics of, and possibilities of articulating, in and out-of-school educational practices. This paper aims (...) at understanding if the occasional outing from primary school premises promotes interruptions in the humanist foundations of school. In order to analyse relations between different institutions and professionals (to be) engaged in educational activities and programmes, Nóvoa ( 2002 , 2009 ) essays will be brought to the discussion, namely his conception of the ‘Public Space of Education’—as a space where culture, education, arts, sports and leisure are shared responsibilities, and where diverse institutions are networked aiming towards societal pluralism. I argue for the possibility of using cities’ public spaces as contexts with a worldly quality to complexify children’s education. Nevertheless, I draw attention to the unbearable educational lightness that these practices may carry if they do not go beyond the praise of chance; as well as to their unsustainable weight if they perpetually repeat school’s normal orders and add up rational discourses.

It is shown that axiomatic extensions of intuitionistic propositional calculus defining univocally new connectives, including those proposed by Gabbay, are strongly complete with respect to valuations in Heyting algebras with additional operations. In all cases, the double negation of such a connective is equivalent to a formula of intuitionistic calculus. Thus, under the excluded third law it collapses to a classical formula, showing that this condition in Gabbay's definition is redundant. Moreover, such connectives can not be interpreted in all Heyting (...) algebras, unless they are already equivalent to a formula of intuitionistic calculus. These facts relativize to connectives over intermediate logics. In particular, the intermediate logic with values in the chain of length n may be "completed" conservatively by adding a single unary connective, so that the expanded system does not allow further axiomatic extensions by new connectives.

This paper is a preliminary investigation into the application of the formal-logical theory of normative positions to the characterisation of normative-informational positions, pertaining to rules that are meant to regulate the supply of information. First, we present the proposed framework. Next, we identify the kinds of nuances and distinctions that can be articulated in such a logical framework. Finally, we show how such nuances can arise in specific regulations. Reference is made to Data Protection Law and Contract Law, among others. (...) The proposed approach is articulated around two essential steps. The first involves identifying the set of possible interpretations that can be given to a particular norm. This is done by using formal methods. The second involves picking out one of these interpretations as the most likely one. This second step can be resolved only by using further information (e.g., the context or other parts of the regulation). (shrink)

The fundamental task of Filosofía de la realidad histórica (Philosophy of Historical Reality) is to put forth historical reality as the ultimate manifestation of reality, as the proper object of philosophy. Ellacuría develops the concept of historical reality as the synthesis of the Hegelian-Marxian dialectic and Xavier Zubiri’s radicalization of Scholastic realism. Historical reality is physical, not conceptual; material, not ideal; concrete, not abstract. Historical reality encompassesthe material, biological, individual, and social moments of reality. And when it is considered (...) in its totality, as a dynamic and differentiated structure of its moments, functions, and relations, historical reality forms a transcendental system—intramundane metaphysics.

Goodman’s style may be elusive sometimes, so that it may result difficult to interpret what he really has in mind. This is a consequence of his masterful use of irony and metaphorical language. This difficulty of interpretation affects important parts of his philosophical thoughts and had led to misunderstandings. In the present article, I discuss the significance of Goodman’s pluralism, one of his most relevant theses. I try to show that Goodman’s pluralism does not lead to skepticism or the relativism (...) of “anything goes”. One of the most common arguments directed against Goodman’s pluralism is that his attempt to provide a genuine standard of “rightness” fails, leaving us without a conception of truth or an appropriate substitute. I will argue that the conclusion of this argument is false, trying to show that Goodman’s aim of defending an irrealist pluralism is perfectly coherent and defensible against the common interpretation of his critics.

Increasing interest has been paid to applications of fluorescence measurements to analyze physiological mechanisms in living cells. However, few studies have taken advantage of DNA quantification by fluorometry for dynamic assessment of chromatin organization as well as cell motion during the cell cycle. This approach involves both optimal conditions for DNA staining and cell tracking methods. In this context, this report describes a stoichiometric method for nuclear DNA specific staining, using the bisbenzimidazole dye Hoechst 33342 associated with verapamil, a calcium (...) membrane channel blocker. This method makes it possible to correlate variations of nuclear DNA content with cell motion in cells that are maintained alive. Motion measurement is the second goal of this paper and it explains the snake-spline method, and the associated cell following method. (shrink)
The focus of this paper is employee ownership, specifically the role of employee ownership in value creation. Based on a sample of 163 French companies, we have measured the impact of employee share ownership on value creation for both shareholders and stakeholders. Only companies with a sustained employee ownership policy over a 5-year period (from 2001 to 2005), as defined by the French Federation of Employee and Former Employee Shareholders (FAS), have been considered. The results indicate that employee share ownership (...) plans have no effect on shareholders’ or stakeholders’ value creation. (shrink)

This study investigated the effect of stroking vs. simple human presence on later reactions of dairy cows to routine veterinary handling. While in two groups of cows the experimenter stroked the ventral part of the neck (Neck, N = 14) or the withers (Withers, N = 15) for three consecutive weeks, the third group was exposed to close visual presence (Control, N = 14). After the treatment period the cows were subjected to rectal palpation. The three groups differed significantly in (...) stepping during rectal palpation, which occurred less often in Neck- and Withers-animals than in control animals. Heart rate increase was significantly higher in the control group than in the two stroking groups. Previous stroking led to fewer stress reactions during the rectal palpation, possibly due to a combined effect of improved relationship towards and thus perception of humans and lasting anti-stress effects of tactile stimulation.

It is shown that Friedman's problem, whether there exists a proper extension of first order logic satisfying the compactness and interpolation theorems, has extremely simple positive solutions if one considers extensions by generalized (finitary) propositional connectives. This does not solve, however, the problem of whether such extensions exist which are also closed under relativization of formulas.

In our paper we aim at reflecting upon the extent to which educational theory may be used as a framework in the analysis of policy documents. As policy texts are ‘heteroglossic in character’ (Lingard and Ozga, in The Routledge Falmer reader in education policy and politics, Routledge, London and New York, 2007 , p. 2) and create “circumstances in which the range of options available in deciding what to do are narrowed or changed” (Ball in, Education policy and social class: (...) The selected works of Stephen J Ball, Routledge, London and New York, 2006 , p. 46), they need to be theoretically tackled in their underlying assumptions and implications. This proposal draws on an analysis of two sets of documents of the European Union: texts produced between 2000 and 2006, underlying the European Union programmes; and texts produced by a working group focusing on the key competences of Lifelong Learning (2003–2006). Initially, the framework for the analysis of different documents was grounded on the existing research in the field of educational policy. Now we attempt a secondary analysis of the collected data by transposing the borders of this particular and highly prolific field. We argue that what is outside the texts may reshape what is inside the texts. Educational theory allows us to define some conceptual tools in order to question the documents as political apparatus which open and constrain possibilities. Therefore, we will use educational theory as an arena where different matters, perspectives and possibilities may be explored and assembled. We have engaged in a conversation with both the data and some theoretical approaches. Central to this conversation are the concepts of “ignorant schoolmaster” (Rancière, in The ignorant schoolmaster five lessons in intellectual emancipation, Stanford University Press, Stanford, 1991 ), “learning contexts” (Edwards, in Rethinking contexts for learning and teaching, Routledge, Oxon and New York, 2009a , b ), and “experience” (Larrosa, in Revista Brasileira de Educação, 19:20–28, 2002 ).

The conceptual framework of this paper is the structural conception of theories as formulated by Sneed-Stegmüller. We present an informal set-theoretical axiomatization of M. F. Xavier Bichat’s theory of the constitution of the organism, which conceived the tissue as the ultimate constitutive element of the living beings, and a reformulation of our previous axiomatization of the cell theory. We propose a tentative relation of reduction between both theories which possibilitates the derivation of the axioms of the tissue theory from (...) those of the cell theory. The limits and problems of the axiomatization are discussed and brief reference is being made to some historical aspects of the reception of the cell theory. (shrink)
Estimation of the repartition of asynchronous cells in the cell cycle can be explained by two hypotheses:– - the cells are supposed to be distributed into three groups: cells with a 2c DNA content (G0/1 phase), cells with a 4c DNA content (G2+M phase) and cells with a DNA content ranging from 2c to 4c (S phase); – - there is a linear relationship between the amount of fluorescence emitted by the fluorescent probe which reveals the DNA and the DNA (...) content. According to these hypotheses, the cell cycle can be represented by the following equation. (shrink)
Montaigne insiste ao longo dos Ensaios em seu desprezo pela retórica. Mas como procuraremos mostrar aqui, sua "forma natural" inscreve-se em grande medida dentro dos termos da própria retórica, sob uma mobilização particular dos preceitos e convenções tradicionalmente apropriados à escrita em primeira pessoa, especialmente aqueles que regulavam o sermo familiaris, gênero recuperado pela primeira vez na Renascença por Petrarca. Retomamos assim, para desenvolvê-la, a fecunda intuição de Hugo Friedrich que, em sua clássica obra sobre os Ensaios de Montaigne, aponta (...) o seu parentesco com a forma epistolar de Petrarca, sem, porém, acompanhá-lo quando distancia o ensaio da epístola familiar, por entendê-lo como marco de ruptura com os procedimentos da retórica e, assim, com toda a prosa artisticamente trabalhada do humanismo. Montaigne insists throughout the course of the Essays on his disdain for rhetoric. But as we try to expose here, his "natural form" includes itself to a large extent in the terms of rhetoric itself, under a particular usage of the precepts and conventions traditionally appropriate to the discourse in first person, especially those which regulated the sermo familiaris, genre recuperated for the first time in the Renaissance by Petrarch. We retake, in order to develop it, the fruitful intuition of Hugo Friedrich in his classical work about Montaigne's Essays, indicating its kinship with Petrarch's epistolary form, without, however, following him when he moves the essay away from the familiar epistle by interpreting the essay as a rupture with the rhetorical procedures and therefore with all the artistically worked prose of humanism.

This is culture understood as a web of meanings that actually builds our identity by providing guidance in the complexity of our environment. It is the complex interplay between identity and alterity, between interiority and exteriority, between familiarity and strangeness.
