Drawing on an analysis of austerity reforms in Greece and Portugal during the sovereign debt crisis from 2009 onwards, we show how the nature of the linkages between parties and citizens shapes party strategies of fiscal retrenchment. We argue that parties which rely to a greater extent on the selective distribution of state resources to mobilize electoral support (clientelistic linkages) are more reluctant to agree to fiscal retrenchment because their own electoral survival depends on their ability to control state budgets to reward clients. In Greece, where parties relied extensively on these clientelistic linkages, austerity reforms have been characterized by recurring conflicts and disagreements between the main parties, as well as a fundamental transformation of the party system. By contrast, in Portugal, where parties relied less on clientelistic strategies, austerity reforms have been more consensual because fiscal retrenchment challenged to a lesser extent the electoral base of the mainstream parties.

El capitalismo está hoy atravesando un momento de turbulencias estructurales. Para unos se trata de una crisis económica, para otros de una crisis financiera y, aún para algún otro autor, mas bien debería hablarse de una crisis global de sociedad. ¿Pueden tan diversas opiniones converger en sus análisis? No es tarea fácil ya que cada cual suele hablar desde su propia perspectiva académica, cuando no, incluso circunscrito a un determinado enfoque teórico. Además, la mayoría de los debates han girado en torno a la economía y la corriente principal de la ciencia económica, la teoría neoclásica, por su propia naturaleza es incapaz de aportar más claridad. Los supuestos en los que basa sus modelos y teorías, que tanto cientifismo le han conferido, impiden precisamente captar la dimensión del fenómeno. De ahí salen algunas recetas para intentar paliar nuestros males, como por ejemplo, la sugerencia de que si dejamos actuar a los mercados, su lógica va a conducir a reparar los desajustes que se han venido produciendo. Pero, ¿qué son los mercados? ¿se trata de algo mágico que actúa con finalidad propia y con un objetivo específico?

Crassulacean acid metabolism (CAM) photosynthesis is an adaptation to water and atmospheric CO2 deficits that has been linked to diversification in dry-adapted plants. We investigated whether CAM evolution can be associated with the availability of new or alternative niches, using Eulophiinae orchids as a case study. Carbon isotope ratios, geographical and climate data, fossil records and DNA sequences were used to: assess the prevalence of CAM in Eulophiinae orchids; characterize the ecological niche of extant taxa; infer divergence times; and estimate whether CAM is associated with niche shifts. CAM evolved in four terrestrial lineages during the late Miocene/Pliocene, which have uneven diversification patterns. These lineages originated in humid habitats and colonized dry/seasonally dry environments in Africa and Madagascar. Additional key features (variegation, heterophylly) evolved in the most species-rich CAM lineages. Dry habitats were also colonized by a lineage that includes putative mycoheterotrophic taxa. These findings indicate that the switch to CAM is associated with environmental change. With its suite of adaptive traits, this group of orchids represents a unique opportunity to study the adaptations to dry environments, especially in the face of projected global aridification.

La prise en charge et le suivi de personnes en situation de handicap mental souffrant de troubles psychiques et se trouvant donc à l'interface des domaines socio:éducatif et psychiatrique, constituent des défis complexes en matière de collaboration interprofessionnelle. Dans le canton de Vaud, les acteurs concernés par ce problème s'efforcent depuis de nombreuses années de créer des réseaux pluridisciplinaires visant un meilleur échange entre professionnels et le développement de compétences et de connaissances permettant d'améliorer le bien:être des bénéficiaires. Ce travail se propose ainsi d'étudier et de questionner ces modalités de travail dans une perspective socioculturelle (Vygotski, 1934/1997), afin d'en comprendre le fonctionnement, d'en éclairer les mécanismes et de fournir des pistes de réflexion aux professionnels. Il repose sur un travail de terrain mené auprès des membres du Dispositif de Collaboration Psychiatrie Handicap Mental (DCPHM) du Département de psychiatrie du CHUV, dont la mission principale est de faciliter la collaboration entre les institutions socio:éducatives et psychiatriques spécialisées dans le suivi des personnes en situation de handicap mental et souffrant de troubles psychiques. Le travail empirique est basé sur une approche qualitative et compréhensive des interactions sociales, et procède par une étude de terrain approfondie. Les données recueillies sont variées : notes de terrain et récolte de documentation, enregistrement de réunions d'équipe au sein du DCPHM et de réunions de réseau, et entretiens de différents types. L'analyse montre que le travail de collaboration qui incombe à l'équipe est constitué d'obstacles qui sont autant d'occasions de développement professionnel et de construction identitaire. Les résultats mettent en lumière des mécanismes discursifs de catégorisation concourant à la fois à la construction des patients comme objets d'activité, et à la construction d'une place qui légitime les interventions de l'équipe dans le paysage socio:éducatif et psychiatrique vaudois et la met au centre de l'arène professionnelle. -- Care and follow:up for people with mental disabilities suffering from psychological disorders : therefore at the interface between the socio:educational and psychiatric fields : represent complex challenges in terms of interprofessional collaboration. In the canton of Vaud, the caregivers involved in this issue have been trying for years to build multidisciplinary networks in order to better exchange between professionals and develop skills and knowledge to improve the recipients' well:being. This work thus proposes to study and question these working methods in a sociocultural perspective (Vygotski, 1934/1997) so as to understand how they operate, highlight inherent mechanisms and provide actionable insights to the professionals. It is based on fieldwork conducted among members of the Dispositif de Collaboration Psychiatrie Handicap Mental (DCPHM), of the Psychiatry Department at the CHUV University Hospital in Lausanne, whose main mission is to facilitate collaboration between the socio:educational and psychiatric institutions specialising in monitoring people presenting with both mental handicap and psychiatric disorder. The empirical work is based on a qualitative and comprehensive approach to social interactions, and conducted based on an in:depth field study. The data collected are varied - field notes and documentation collection, recordings of team meetings within the DCPHM and network meetings, and various types of interviews. The analysis shows that the collaborative work that befalls the team consists of obstacles, all of which provide opportunities for professional development and identity construction. The results highlight discursive strategies of categorisation which contribute both to the construction of the patients as objects of activity and to building a position that legitimates the team's interventions in the socio: educational and psychiatric landscape of canton Vaud and puts it in the centre of the professional arena.

La relación entre las organizaciones y la sociedad es muy sutil. Debido a las diferentes motivaciones de las dos, es inevitable que tienen conflictos o disputas entre la organización y los públicos. Estos conflictos o crisis afectan mucho a la imagen corporativa y la credibilidad en el público. Cómo gestionar la crisis y conflictos de comunicación entre las organizaciones y públicos es un problema importante para los gabinetes de comunicación. Se hará la comparación entre el accidente de vuelo de Asiana Airlines y de Malaysia Airlines; y se hablará del accidente nuclear de Fukushima de 2011

The purpose of this work is to evaluate the possible impact of the so-called “crisis of the 3rd century” in the area between Tarraco (Tarragona) and Saguntum (Sagunt), currently corresponding to the southern limit of Catalonia and the north of Valencia, which during the Roman era made up the southernmost part of the conventus Tarraconensis. The processes of change experienced in rural settlements and cities between the Severan dynasty and the beginning of the tetrarchy are analyzed, and the importance of the city-country relationship is examined to explain these changes. The extent of the Frankish invasion during of the Gallic period, initially substantiated by sources and now by archaeological evidence, is discussed. The study of coin hoards (treasures and deposits) from the second half of the 3rd century, found in abundance in this area, is a very interesting aspect of this topic. In addition, a quantitative approach is used to study the population changes experienced as a result of the rural settlement of this area during the 3rd century, between the High and the Low Empires.

In this study we use historical emission data from installations under the European Union Emissions Trading System, -EU ETS- to evaluate the impact of this policy on industrial greenhouse gas emissions during the first two trading phases, 2005-2012. As such the analysis seeks to disentangle two causes of emission abatement: that attributable to the EU ETS and that attributable to the economic crisis that hit the EU in 2008/09. Using a panel data approach the estimated emissions reduction attributable to the EU ETS is about 21 per cent of the total emission abatement during the observation period. These results suggest therefore that the lion’s share of abatement was attributable to the effects of the economic crisis, a finding that has serious implications for future policy adjustments affecting core elements of the EU ETS, including the distribution of EU emission allowances.

OBJECTIVE: We evaluated whether regional differences in physical activity (PA) and sedentary behaviour (SB) existed along language boundaries within Switzerland and whether potential differences would be explained by socio-demographics or environmental characteristics. METHODS: We combined data of 611 children aged 4 to 7 years from four regional studies. PA and SB were assessed by accelerometers. Information about the socio-demographic background was obtained by questionnaires. Objective neighbourhood attributes could be linked to home addresses. Multivariate regression models were used to test associations between PA and SB and socio-demographic characteristics and neighbourhood attributes. RESULTS: Children from the German compared to the French-speaking region were more physically active and less sedentary (by 10-15 %, p < 0.01). Although German-speaking children lived in a more favourable environment and a higher socioeconomic neighbourhood (differences p < 0.001), these characteristics did not explain the differences in PA behaviour between French and German speaking. CONCLUSIONS: Factors related to the language region, which might be culturally rooted were among the strongest correlates of PA and SB among Swiss children, independent of individual, social and environmental factors.

BACKGROUND: In the context of the European Surveillance of Congenital Anomalies (EUROCAT) surveillance response to the 2009 influenza pandemic, we sought to establish whether there was a detectable increase of congenital anomaly prevalence among pregnancies exposed to influenza seasons in general, and whether any increase was greater during the 2009 pandemic than during other seasons. METHODS: We performed an ecologic time series analysis based on 26,967 pregnancies with nonchromosomal congenital anomaly conceived from January 2007 to March 2011, reported by 15 EUROCAT registries. Analysis was performed for EUROCAT-defined anomaly subgroups, divided by whether there was a prior hypothesis of association with influenza. Influenza season exposure was based on World Health Organization data. Prevalence rate ratios were calculated comparing pregnancies exposed to influenza season during the congenital anomaly-specific critical period for embryo-fetal development to nonexposed pregnancies. RESULTS: There was no evidence for an increased overall prevalence of congenital anomalies among pregnancies exposed to influenza season. We detected an increased prevalence of ventricular septal defect and tricuspid atresia and stenosis during pandemic influenza season 2009, but not during 2007-2011 influenza seasons. For congenital anomalies, where there was no prior hypothesis, the prevalence of tetralogy of Fallot was strongly reduced during influenza seasons. CONCLUSIONS: Our data do not suggest an overall association of pandemic or seasonal influenza with congenital anomaly prevalence. One interpretation is that apparent influenza effects found in previous individual-based studies were confounded by or interacting with other risk factors. The associations of heart anomalies with pandemic influenza could be strain specific.

La presente comunicación parte de la premisa que la actual crisis económica en el Estado español, así como su gestión política, se ven configuradas por el género, adoptando para ello como eje analítico el concepto de acumulación por desposesión. El aumento de la carga total de trabajo de las mujeres, así como la intensificación de sus responsabilidades reproductivas responden a una estrategia político-económica de privatización y re-hogarización de la reproducción en aras de la supervivencia de la economía considerada real o lo que también llamamos cercamiento de la reproducción. Éste toma la forma de un reforzamiento actualizado de la división sexual del trabajo sin por ello reducir el rol económico de las mujeres sino, en realidad, fortaleciéndolo. Un análisis a la crisis actual adoptando la desposesión de la reproducción como punto de partida no sólo nos permite ubicar las desigualdades de género en el centro de los debates en torno a la crisis sino que a su vez abre el camino para pensar en alternativas a la actual organización social de la reproducción teniendo en cuenta, de manera simultánea, las esferas de la familia, de las administraciones públicas y de lo que se viene llamando el ámbito de “lo común”. Es a partir de esta conceptualización que se avanza una categorización de las diferentes tipologías de bienes en que se pueden concebir y convertir los cuidados y se reflexiona sobre la posibilidad, las oportunidades y los riesgos de una nueva organización social del cuidado en tanto que bien común.
