Listening to the public: enacting power : citizen access, Standing and influence in public participation discourses

Public participation in environmental governance is typically associated with citizen access to power despite many closures and limitations having been identified in participatory processes. This article proposes an analytical framework to analyse discursive practices involved in public consultation processes. Critical Discourse Analysis is used to examine and appraise citizens’ access, standing and influence. We apply that framework to a ‘notice and comment’ process on a hydroelectric power plan in Portugal and show that it was discursively managed to justify the decision of constructing 10 large dams and to reject critical or alternative views. Citizens’ access, standing and influence were constrained through diverse discursive practices which (re)produced very unequal power relationsbetween policy proponents and participating individuals. More generally, the article illustrates the potential of Critical Discourse Analysis to assess voice(s) in policy processes. Focusing on argumentative, interactional and rhetorical levels, and how they are interwoven in public consultation discourses, the proposed framework is conceivably applicable in other studies.

O que pensam os jornalistas sobre seu papel no enfrentamento das mudanças climáticas: as percepções dos profissionais da Gazeta do Povo no Paraná, Brasil

Este artigo tem como objetivo analisar as percepções sobre enfrentamento das mudanças climáticas dos jornalistas que participaram do processo de produção de notícias sobre este assunto no jornal Gazeta do Povo, o de maior circulação no estado do Paraná, sul do Brasil, no ano de 2013, e relacioná-las com a função social do jornalismo e suas potencialidades no que tange à governança dos riscos climáticos, especialmente no nível local. A análise apresentada faz parte da pesquisa de doutorado da primeira autora que pretende concatenar as diferentes etapas do circuito da notícia pensando na comunicação, percepção e governança atreladas a questão climática. Neste texto nos centramos na discussão do papel da imprensa e do próprio profissional diante do problema das alterações do clima, concluindo que os respondentes atribuem funções sociais significativas à imprensa, mas não se veem como elementos-chave na promoção da governança climática, atribuindo mais responsabilidades a outros setores e justificando suas limitações a partir de normas e critérios profissionais.

Desenvolvimento de talentos no desporto : aspectos psicológicos

A presente investigação tem como principal objetivo compreender a relevância de diversos fatores sociodemográficos e psicossociais inerentes ao desenvolvimento do talento em contexto desportivo, numa perspectiva multidimensional. Procedeu-se a uma avaliação quantitativa de jogadores de futebol, integrados num clube de elite, com idades compreendidas entre os 13 e os 19 anos. No sentido de avaliar os construtos psicológicos considerados no presente estudo (motivação, perfecionismo, suporte parental, resiliencia, coping e compromisso) foram utilizados os seguintes questionários: Sport Motivation Scale - SMS (Pelletier et al., 1995); Multidimensional Perfectionism Scale – MPS (Frost, Marten, Lahart, & Rosenblate, 1990); Own Memories of Parental Rearing – EMBU (Perris, Jacobson, Lindstörm, Von Knorring, & Perris, 1980); Resilience Scale – RS (Wagnild & Young, 1993); Athletic Coping Skills – ACSI 28 (Smith, Schutz, Smoll, & Ptacek, 1995); e Elite Athlete Commitment Scale – EACS (Ramadas, Serpa, Rosado, Gouveia & Maroco, 2013). A significância da variável nível de prestação (elite/sub-elite; dispensados/retidos) sobre os diversos constructos psicológicos foi avaliada através da análise da covariância multivariada (MANCOVA), da análise de equações estruturais (CBSEM) e da técnica de míninos quadrados parciais (PLS). Os jogadores mais bem sucedidos (jogadores de elite e jogadores retidos) percecionaram maior suporte parental, demonstraram níveis mais elevados de compromisso, resiliência, autodeterminação, capacidade de adaptação e confronto, assim como um perfeccionismo ajustado. No que concerne às variáveis sociodemográficas, constatou-se que os jogadores retidos jogam predominantemente no segundo ano do respetivo grupo de idade e têm uma idade inferior aos jogadores dispensados. Os resultados obtidos poderão constituir um relevante suporte para futuros programas educacionais que incidam sobre temáticas relacionadas com os compromissos necessários à prossecução e manutenção de níveis de elite, estratégias de coping, gestão da rotina diária, e o papel dos pais no processo de formação do jovem desportista.

Labor productivity in Spain: 1977-2002

This study examines the evolution of labor productivity across Spanish regions during the period from 1977 to 2002. By applying the kernel technique, we estimate the effects of the Transition process on labor productivity and its main sources. We find that Spanish regions experienced a major convergence process in labor productivity and in human capital in the 1977-1993 period. We also pinpoint the existence of a transition co-movement between labor productivity and human capital. Conversely, the dynamics of investment in physical capital seem unrelated to the transition dynamics of labor productivity. The lack of co-evolution can be addressed as one of the causes of the current slowdown in productivity. Classification-JEL: J24, N34, N940, O18, O52, R10

Early antibiotic administration affects the gut barrier function and the immune response to oral antigen in suckling rats

Abstract: The increasingly high hygienic standards characterizing westernized societies correlate with an increasingly high prevalence of allergic disease. Initially based on these observations, the hygiene hypothesis postulates that reduced microbial stimulation during infancy impairs the immune system development and increases the risk of allergy. Moreover, there is increasing evidence that the crosstalk existing between the intestine and the resident microbiota is crucial for gut homeostasis. In particular, bacterial colonization of the gut affects the integrity of the gut barrier and stimulates the development of the gut associated immune tissue, both phenomena being essential for the immune system to mount a controlled response to food antigens. Therefore, alterations in the microbial colonization process, by compromising the barrier homeostasis, may increase the risk of food allergy. In this context, antibiotic treatment, frequently prescribed during infancy, affects gut colonization by bacteria. However, little is known about the impact of alterations in the colonization process on the maturation of the gut barrier and on the immunological response to oral antigens. The objective of this work was to determine the impact of a commercial antibiotic preparation employed in pediatric settings on the gut barrier status at the critical period of the suckling/weaning transition and to evaluate the physiological consequences of this treatment in terms of immune response to food antigens. We established an antibiotic-treated suckling rat model relevant to the pediatric population in terms of type, dose and route of administration of the antibiotic and of changes in the patterns of microbial colonization. Oral tolerance to a novel luminal antigen (ovalbumin) was impaired when the antigen was introduced during antibiotic treatment. These results paralleled to alterations in the intestinal permeability to macromolecules and reduced intestinal expression of genes coding for the major histocomptatibility complex II molecules, which suggest a reduced capacity of antigen handling and presentation in the intestine of the antibiotic-treated animals. In addition, low luminal IgA levels and reduced intestinal expression of genes coding for antimicrobial proteins suggest that protection against pathogens was reduced under antibiotic treatment. In conclusion, we observed in suckling rats that treatment with abroad-spectrum antibiotic commonly used in pediatric practices reduced the capacity of the immune system to develop tolerance. The impact of the antibiotic treatment on the immune response to the antigen-was likely mediated by the alterations of the gut microbiota, through impairment in the mechanisms of antigen handling and presentation. This work reinforces the body of data supporting a key role of the intestinal microbiota modulating the risk of allergy development and leads us to propose that the introduction of new food antigens should be avoided during antibiotic treatment in infants. Résumé: L'augmentation du niveau d'hygiène caractérisant les sociétés occidentales semble être fortement corrélée avec l'augmentation des cas d'allergie dans ces pays. De cette observation est née l'hypothèse qu'une diminution des stimuli microbiens pendant l'enfance modifie le développement du système immunitaire augmentant ainsi le risque d'allergie. En ce sens, un nombre croissant de données indiquent que les interactions existant entre l'intestin et les bactéries résidantes sont cruciales pour l'équilibre du système. En effet, la présence de bactéries dans l'intestin affecte l'intégrité de sa fonction de barrière et stimule le développement du système immunitaire intestinal. Ces deux paramètres étant essentiels à la mise en place d'une réponse contrôlée vis à vis d'un antigène reçu oralement, toute modification du processus naturel de colonisation compromettant l'équilibre intestinal pourrait augmenter le risque d'allergie. Les traitements aux antibiotiques, fréquemment prescrits en pédiatrie, modifient de façon conséquente le processus de colonisation bactérienne. Cependant peu de données existent concernant l'impact d'une altération du processus de colonisation sur la maturation de la barrière intestinale et de la réponse immunitaire dirigée contre un antigène. L'objectif de ce travail était de déterminer l'impact d'un antibiotique commercial et employé en pédiatrie sur l'état de la barrière intestinale au moment critique du sevrage et d'évaluer les conséquences physiologiques d'un tel traitement sur la réponse immune à un antigène alimentaire. Nous avons mis en place un modèle de rats allaités, traités à l'antibiotique, le plus proche possible des pratiques pédiatriques, en terme de nature, dose et voie d'administration de l'antibiotique. Nous avons constaté que l'établissement de la tolérance orale à un nouvel antigène (l'ovalbumine) est altéré quand celui-ci est donné pour la première fois au cours du traitement antibiotique. Ces résultats coïncident avec une diminution de la perméabilité intestinale aux macromolécules, ainsi qu'avec une diminution de l'expression des gènes codant pour les molécules du complexe majeur d'histocomptatibilité de classe II, suggérant une modification de l'apprêtement et de la présentation de l'antigène au niveau intestinal chez les rats traités à l'antibiotique. De plus, un faible taux d'IgA et une diminution de l'expression des gènes codant pour des protéines antimicrobiennes, observés après l'administration d'antibiotique, laissent à penser que la protection contre un pathogène est diminuée lors d'un traitement antibiotique. En conclusion, nous avons observé qu'un traitement antibiotique à large spectre d'activité, couramment utilisé en pédiatrie, réduit la capacité d'induction de la tolérance orale chez le rat allaité. L'impact du traitement antibiotique sur la réponse immune semble induite par l'altération de la flore intestinale via son effet sur les mécanismes d'apprêtement et de présentation de l'antigène. Ce travail renforce l'ensemble des données existantes qui accorde à la flore intestinale un rôle clef dans la modulation du risque de développement d'allergie et nous amène à recommander d'éviter l'introduction d'un nouvel aliment lorsqu'un enfant est traité aux antibiotiques.

Progresión tumoral y búsqueda de nuevas dianas terapéuticas en la familia de tumores del sarcoma de Ewing: función biológica de la caveolina-1

El sarcoma de Ewing es el segundo tumor óseo infantil más frecuente y presenta una alta incidencia de enfermedad metastática. Este tipo de tumores presentan una traslocación génica característica que da origen a una proteína de fusión, normalmente EWS/FLI1. Esta proteína de fusión actúa como factor de transcripción aberrante regulando la expresión de diferentes genes implicados en la iniciación, mantenimiento y progresión del tumor. Nuestro grupo describió como uno de estos genes diana a la caveolina 1 (CAV1) describiendo además su papel determinante en el fenotipo maligno del sarcoma de Ewing, en la tumorigénesis y en la resistencia a apoptosis inducida por quimioterapia. Para investigar el papel concreto de CAV1 en el proceso metastático de este sarcoma, creamos un modelo de baja expresión de CAV1 en líneas celulares de sarcoma de Ewing y determinamos cambios en su capacidad migratoria, invasiva y metastática. En los ensayos in vitro hallamos una menor capacidad migratoria de las células knockdown de CAV1 y una reducción en la expresión de MMP9 y en la actividad de MMP2. La regulación de la actividad de MMP2 parece estar relacionada con la posible regulación que ejerce CAV1 en la función de MT1-MMP, proteína fundamental para la activación de MMP2. Por otro lado, en este estudio proponemos que CAV1 promueve la expresión de MMP9 tanto transcripcionalmente, regulando la vía de señalización ERK1/2, como a nivel post-transcripcional regulando la vía RSK1/rpS6. Además, en los ensayos de metástasis experimental in vivo las células knockdown de CAV1 presentaron una menor incidencia de metástasis pulmonar, hecho que correlacionó con una disminución en la expresión de SPARC, una proteína de adhesión importante en procesos metastáticos. En resumen, nuestros resultados evidencian la importancia de CAV1 en el proceso metastático del sarcoma de Ewing.

A re-focused and re-energised National Drugs Strategy, Issue 14, Summer 2005

The Mid-Term Review1 of the National Drugs Strategy 2001–2008, published on 2 June 2005, recommends a number of additions and amendments to the existing Strategy, including making rehabilitation a new, ‘fifth’ pillar of the Strategy. The Steering Group that oversaw the Review, and the extensive consultation process on which it is based, found that the aims and objectives of the Strategy are fundamentally sound. While what has been achieved varies from action to action, progress has been made across the four pillars of supply reduction, prevention, treatment and research, and in the co-ordination of the institutional structures of the Strategy. The Review recommends the addition of eight new actions, the replacement of nine of the existing actions and amendments to a further eight. It also recommends revisions to the Strategy’s key performance indicators, reflecting new developments and data availability. The recommendations serve to ‘re-focus and re-energise’ the Strategy in the remaining period up to 2008.This resource was contributed by The National Documentation Centre on Drug Use.

A new species of the genus Panstrongylus from French Guiana (Heteroptera; Reduviidae; Triatominae)

Panstrongylus mitarakaensis n. sp. is described from French Guiana. Morphological characters are provided. This small species, less robust than other Panstrongylus species, shows a pronotum shape similar to species of the "P. lignarius complex". However, others characters such as the postocular part of head, the obsolete tubercle on the anterior lobe of pronotum, and the lateral process on the antenniferous tubercle distinguish it from the species in that complex. The taxonomic key of the genus Panstrongylus is actualized.

Policy gradient based Reinforcement Learning for real autonomous underwater cable tracking

This paper proposes a field application of a high-level reinforcement learning (RL) control system for solving the action selection problem of an autonomous robot in cable tracking task. The learning system is characterized by using a direct policy search method for learning the internal state/action mapping. Policy only algorithms may suffer from long convergence times when dealing with real robotics. In order to speed up the process, the learning phase has been carried out in a simulated environment and, in a second step, the policy has been transferred and tested successfully on a real robot. Future steps plan to continue the learning process on-line while on the real robot while performing the mentioned task. We demonstrate its feasibility with real experiments on the underwater robot ICTINEU AUV

Cuestiones controvertidas en evaluación económica (I): perspectiva y costes de intervenciones sanitarias.

Economic evaluation of health care interventions has experienced a strong growth over the past decade and is increasingly present as a support tool in the decisions making process on public funding of health services and pricing in European countries. A necessary element using them is that agents that perform economic evaluations have minimum rules with agreement on methodological aspects. Although there are methodological issues in which there is a high degree of consensus, there are others in which there is no such degree of agreement being closest to the normative field or have experienced significant methodological advances in recent years. In this first article of a series of three, we will discuss on the perspective of analysis and assessment of costs in economic evaluation of health interventions using the technique Metaplan. Finally, research lines are proposed to overcome the identified discrepancies.

Biochemical markers of fatal hypothermia.

The aim of this study was to investigate the usefulness of postmortem biochemical investigations in the diagnosis of fatal hypothermia. 10 cases of fatal hypothermia and 30 control cases were selected. A series of biochemical parameters, such as glucose, acetone, 3-beta-hydroxybutyrate, isopropyl alcohol, free fatty acids, adrenaline, growth hormone, adrenocorticotropic hormone, thyroid-stimulating hormone, cortisol, calcium, magnesium, C-reactive protein, procalcitonin as well as markers of renal and cardiac functions were measured in blood, postmortem serum from femoral blood, urine, vitreous and pericardial fluid. The results suggested that deaths due to hypothermia, especially in free-ethanol cases, are characterized by increased ketone levels in blood and other biological fluids, increased adrenaline concentrations in urine, increased cortisol levels in postmortem serum from femoral blood and increased free cortisol values in urine. Increased or decreased levels of other biological parameters are either the result of terminal metabolic changes or the expression of preexisting diseases and may provide information to elucidate the death process on a case-by-case basis.

The Nationalism of stateless nations and Europe. The Catalan case

This paper analyzes how the ideas and concepts of Europe have developed in Catalonia, under the conditions of a decentralizing “nation-state” (Spain) on one hand, and the European integration process on the other. It analyzes the programmes, manifestations of political leaders, and political actions of the Catalan political parties, specially the nationalists, from the setting up of the Spanish state of autonomies (1977-1982) until today. The paper tries to show how, in multilevel governance, holistic and enthusiastic visions of an economically and political integrating Europe as a “natural ally” of a Catalan nationalism were partially replaced by more pragmatic and even more critical assessments.
