Cómo leer los relatos bíblicos. Iniciación al análisis narrativo

La Biblia es uno de los más fabulosos tesoros de historia(s) de la humanidad, pues desde la noche de los tiempos los creyentes relatan. Pero no lo hacen de cualquier manera. Largamente elaborados en su etapa oral, pacientemente redactados, los relatos bíblicos obedecen a unas sutiles reglas de composición. Tras las historias aparentemente ingenuas se esconde la fina estrategia de un narrador. El libro de Daniel Marguerat e Yvan Bourquin -el primer manual de iniciación al análisis narrativo publicado en español- conduce al lector por los entresijos del relato bíblico para observar su construcción. Este descubrimiento de la arquitectura oculta de los textos lleva a plantearse de manera nueva su significación. Con gran claridad pedagógica, los autores han dispuesto un recorrido que permite descubrir los instrumentos del análisis narrativo, estudiar su aplicación y evaluar su eficacia. Toda la magia de la lectura queda con ello iluminada.

"Pa'que veas que te pido perdón en delante toda España" : pragmalingüística y análisis del discurso en los diálogos del talk show televisivo "Diario de Patricia" (2001-2011) : aproximaciones teóricas y análisis

Cette thèse s'inscrit dans le cadre de la Pragmalinguistique et d'Analyse du discours oral et offre une étude approfondie d'un talk show télévisuel espagnol, Diario de Patricia, format dans lequel la présentatrice du même nom reçoit des invités pour parler avec eux de leurs problèmes personnels. Ce travail propose une relecture de grandes théories pragmatiques (comme la Théorie des actes du langage, le Principe de coopération, la Théorie de la politesse ou encore la Théorie de la pertinence) et leur application à des discours réels. Les principes de la linguistique de l'interaction permettent également de décrire l'organisation des talk shows, les stratégies discursives de la présentatrice, la façon dont elle prépare chaque émission et planifie les interviews avec ses invités afin de provoquer chez ceux-ci des réactions émotionnelles qui l'intéressent en vue du taux d'audience. Ce travail de recherche présente également une analyse approfondie des mécanismes pragmalinguistiques utilisés par la présentatrice pour imposer son autorité et pour maîtriser la situation d'une façon que l'auteure qualifie de manipulation des invités, toujours sous une apparence d'empathie et de compréhension.

Wildflower areas within revitalized agricultural matrices boost small mammal populations but not breeding Barn Owls

Agro-ecosystems have recently experienced dramatic losses of biodiversity due to more intensive production methods. In order to increase species diversity, agri-environment schemes provide subsidies to farmers who devote a fraction of their land to ecological compensation areas (ECA). Several studies have shown that invertebrate biodiversity is actually higher in ECA than in nearby intensively cultivated farmland. It remains poorly understood, however, to what extent ECA also favour vertebrates, such as small mammals and their predators, which would contribute to restore functioning food chains within revitalized agricultural matrices. We studied small mammal populations among eight habitat types - including wildflower areas, a specific ECA in Switzerland - and habitat selection (radiotracking) by the barn owl Tyto alba, one of their principal predators. Our prediction was that habitats with higher abundances of small mammals would be more visited by foraging Barn owls during the period of chicks' provisioning. Small mammal abundance tended to be higher in wildflower areas than in any other habitat type. Barn owls, however, preferred to forage in cereal fields and grassland. They avoided all types of crops other than cereals, as well as wildflower areas, which suggests that they do not select their hunting habitat primarily with respect to prey density. Instead of prey abundance, prey accessibility may play a more crucial role: wildflower areas have a dense vegetation cover, which may impede access to prey for foraging owls. The exploitation of wildflower areas by the owls might be enhanced by creating open foraging corridors within or around wildflower areas. Wildflower areas managed in that way might contribute to restore functioning food chains within agro-ecosystems.

La geografía en los relatos de viajes castellanos del ocaso de la Edad Media : análisis del discurso y léxico

Résumé Le travail poursuit un triple objectif: A) présenter la place qu'occupe la géographie physique et la géographie urbaine dans un corpus de cinq récits de voyages castillans de la fin du Moyen-Age, en se centrant particulièrement sur le relief, les eaux continentales, les mers, les côtes, le climat, la végétation, la faune et les villes; B) analyser les ressources discursives dont se servent les rédacteurs pour transmettre ces contenus; C) et réunir le lexique géographique des textes, en l'organisant autour des thématiques mentionnées, en définissant les mots et en faisant ressortir leur valeur dans le contexte discursif. L'étude est introduite par une analyse de la situation communicative dans laquelle se forgent les récits du corpus: contexte historique, social, culturel et textuel, d'une part; identité des voyageurs- rédacteurs, identité des destinataires, et objectifs divers aussi bien des voyages que de leur mise en écriture, d'autre part. De cette analyse ressortent quelques intentions et préoccupations communes aux voyageurs-rédacteurs qui pourraient se résumer en: A) une conscience de la difficulté du voyage; B) une conscience de réaliser un mouvement vers un monde éloigné et étrange; C) une volonté de transmettre des connaissances sur le monde; D) un désir de présenter ce qu'ils racontent comme le fruit d'une expérience vécue et de le faire avec véracité. L'analyse introductoire montre également que cette approche du voyage et la conception du récit qui en découle déterminent le choix de certains contenus géographiques et une façon précise d'exposer l'expérience du voyage: les textes transmettent des connaissances sur le monde et construisent un discours informatif sur l'espace, tout en décrivant un univers étrange et en insistant sur leur caractère testimonial. Le corps du travail est articulé en trois parties. Le premier volet permet de faire émerger la place réservée à la géographie, surtout physique, dans les récits. Il dévoile l'intérêt naissant manifesté par les voyageurs-rédacteurs pour la géographie physique et témoigne de la typologie diversifiée des descriptions urbaines. Il éclaire également le rapport intime liant les thématiques privilégiées dans les textes, les intérêts des rédacteurs et de leur public, et les objectifs de chaque récit. La géographie transmise est non-livresque, issue de l'expérience et, par conséquent, partielle. Le deuxième volet montre le fonctionnement d'une description qui est porteuse d'informations sur l'espace et qui véhicule des savoirs sur le monde, en particulier sur le monde inconnu. Les opérations de nommer, mesurer et adjectiver l'espace parcouru, en le comparant ensuite à l'espace connu sont analysées en détail. Cette partie du travail met en exergue les connaissances, les croyances et les valeurs partagées entre rédacteurs et récepteurs sur lesquelles se construit un discours destiné à transmettre de nouveaux savoirs sur le monde. Les textes se présentent, en outre, comme un témoignage basé sur l'expérience des voyageurs: l'importance de l'information acquise par l'ouïe porte les rédacteurs à incorporer dans leurs récits de nombreuses voix qui racontent le monde et fait du discours géographique un discours clairement polyphonique. Enfin, le troisième volet réunit pour la première fois le lexique géographique castillan en usage à la fin du Moyen-Âge. Procédant de textes rédigés par des non spécialistes, il nous permet d'évaluer les connaissances géographiques d'un homme de l'époque et inclut définitions, exemples d'usage des mots en contexte, données étymologiques, diachroniques, morphosyntaxiques, sémantiques et encyclopédiques. Dans son ensemble, la thèse témoigne de l'intérêt d'une approche des récits de voyage par le triple axe thématique, discursif et lexical.

Hacia un modelo de análisis de políticas públicas operativ : Un enfoque basado en los actores, sus recursos y las instituciones

Towards an operative analysis of public policies: An approach focused on actors, resources and institutions. This article develops an analytical model which is centred on the individual and collective behaviour of actors involved during different stages of public policy. We postulate that the content and institutional characteristics of public action (dependent variable) are the result of interactions between political-administrative authorities, on the one hand, and, on the other, social groups which cause or suffer the negative effects of a collective problem which public action attempts to resolve (independent variables). The 'game' of the actors depends not only on their particular interests, but also on their resources (money, time, consensus, organization, rights, infrastructure, information, personnel, strength, political support) which they are able to exploit to defend their positions, as well as on the institutional rules which frame these policy games.

Cáncer de laringe en pacientes menores de 40 años comparado con mayores de 40 años: análisis de pares [Laryngeal cancer in patients younger vs older than 40 years old: a matched-paired analysis].

BACKGROUND: To compare clinical and demographic data between laryngeal cancer patients younger and older than 40 years old. METHODS: Is a matched-paired study, realized from 1989 to 2002. We selected 500 laryngeal cancer patients treated in the National Cancer Institute of Mexico. Fifteen cases of patients younger than 40 years that accomplished inclusion criteria were identified, pair-matched and compared by clinical stage with 33 patients older than 40 years. We analyzed demographic factors and disease-free and Overall Survival by Kaplan-Meier method. RESULTS: We included 9 male and 6 female patients with a mean age of 34 years in contrast to a mean age of 62 years in the comparison group. Four cases in clinical stage I, none clinical stage II, 6 in stage III and 5 in stage IV were included in the younger group and compared to 8 patients in stage I, 15 in stage III and 10 in stage IV in the older group. No differences in demographic variables or lifestyle habits were found. All patients in stage I, are alive in both groups. Disease-free survival not show any differences when comparing stages III and IV (p=NS). Mean disease-free survival was 66 months and mean overall survival was 83 months in the younger group. CONCLUSION: Laryngeal carcinoma is rare in patients younger than 40 years. No gender, clinical or prognostic differences could be identified among the two groups. The prognosis of these patients seems to be only determined by the initial clinical stage.

Spatial weights : constructing weight-compatible exchange matrices from proximity matrices

Exchange matrices represent spatial weights as symmetric probability distributions on pairs of regions, whose margins yield regional weights, generally well-specified and known in most contexts. This contribution proposes a mechanism for constructing exchange matrices, derived from quite general symmetric proximity matrices, in such a way that the margin of the exchange matrix coincides with the regional weights. Exchange matrices generate in turn diffusive squared Euclidean dissimilarities, measuring spatial remoteness between pairs of regions. Unweighted and weighted spatial frameworks are reviewed and compared, regarding in particular their impact on permutation and normal tests of spatial autocorrelation. Applications include tests of spatial autocorrelation with diagonal weights, factorial visualization of the network of regions, multivariate generalizations of Moran's I, as well as "landscape clustering", aimed at creating regional aggregates both spatially contiguous and endowed with similar features.

Minimal analytical characterisation of engineered nanomaterials need for hazard assessment in biological matrices

The safe and responsible development of engineered nanomaterials (ENM), nanotechnology-based materials and products, together with the definition of regulatory measures and implementation of "nano"-legislation in Europe require a widely supported scientific basis and sufficient high quality data upon which to base decisions. At the very core of such a scientific basis is a general agreement on key issues related to risk assessment of ENMs which encompass the key parameters to characterise ENMs, appropriate methods of analysis and best approach to express the effect of ENMs in widely accepted dose response toxicity tests. The following major conclusions were drawn: Due to high batch variability of ENMs characteristics of commercially available and to a lesser degree laboratory made ENMs it is not possible to make general statements regarding the toxicity resulting from exposure to ENMs. 1) Concomitant with using the OECD priority list of ENMs, other criteria for selection of ENMs like relevance for mechanistic (scientific) studies or risk assessment-based studies, widespread availability (and thus high expected volumes of use) or consumer concern (route of consumer exposure depending on application) could be helpful. The OECD priority list is focussing on validity of OECD tests. Therefore source material will be first in scope for testing. However for risk assessment it is much more relevant to have toxicity data from material as present in products/matrices to which men and environment are be exposed. 2) For most, if not all characteristics of ENMs, standardized methods analytical methods, though not necessarily validated, are available. Generally these methods are only able to determine one single characteristic and some of them can be rather expensive. Practically, it is currently not feasible to fully characterise ENMs. Many techniques that are available to measure the same nanomaterial characteristic produce contrasting results (e.g. reported sizes of ENMs). It was recommended that at least two complementary techniques should be employed to determine a metric of ENMs. The first great challenge is to prioritise metrics which are relevant in the assessment of biological dose response relations and to develop analytical methods for characterising ENMs in biological matrices. It was generally agreed that one metric is not sufficient to describe fully ENMs. 3) Characterisation of ENMs in biological matrices starts with sample preparation. It was concluded that there currently is no standard approach/protocol for sample preparation to control agglomeration/aggregation and (re)dispersion. It was recommended harmonization should be initiated and that exchange of protocols should take place. The precise methods used to disperse ENMs should be specifically, yet succinctly described within the experimental section of a publication. 4) ENMs need to be characterised in the matrix as it is presented to the test system (in vitro/ in vivo). 5) Alternative approaches (e.g. biological or in silico systems) for the characterisation of ENMS are simply not possible with the current knowledge.

Minimal analytical characterization of engineered nanomaterials needed for hazard assessment in biological matrices.

Abstract This paper presents the outcomes from a workshop of the European Network on the Health and Environmental Impact of Nanomaterials (NanoImpactNet). During the workshop, 45 experts in the field of safety assessment of engineered nanomaterials addressed the need to systematically study sets of engineered nanomaterials with specific metrics to generate a data set which would allow the establishment of dose-response relations. The group concluded that international cooperation and worldwide standardization of terminology, reference materials and protocols are needed to make progress in establishing lists of essential metrics. High quality data necessitates the development of harmonized study approaches and adequate reporting of data. Priority metrics can only be based on well-characterized dose-response relations derived from the systematic study of the bio-kinetics and bio-interactions of nanomaterials at both organism and (sub)-cellular levels. In addition, increased effort is needed to develop and validate analytical methods to determine these metrics in a complex matrix.
