    Religious affairs have gained prominence in Spanish politics in recent years. Two factors have played a crucial role in raising the profile of religion in the policy agenda: first, the growth of religious diversity due to the rapid influx of immigrants from the global south that has led to the emergence of multiple challenges and controversies concerning the accommodation of religious diversity; second, the effects of the Al-Qaeda attacks on Spanish soil that fostered policymakers’ perception of the need to “do something” to reinforce Muslim newcomers’ loyalty to the host country. In light of these events, the Spanish policy approach has changed considerably in the last years, being the creation of the public foundation Pluralismo y Convivencia in 2004 being the most illustrative case in point. The aim of this paper is to explain the tranfromations in the governance of religious diversity in Spain. Drawing upon qualitative fieldwork done between 2010 and 2013, we argue that three different political logics underlie the developments leading to the current policy outcome: the logic of democratization, the logic of securitisation of Islam and the logic of the Europeanisation of politics. In this paper we explain these transformations by using a sequential combination of three theoretical approaches: a) the church-state relations approach, b) the theory of control and c) the European convergence perspective

    “Are you a real Christian?” Stereotypes, distrust and distinction strategies between “new” and “old” Protestants in Catalonia

    The arrival of a high number of followers of the Protestant faith due to the increase in immigration flows has shaped the configuration, expectations for future growth and the public role of the Protestant community in Catalonia. However, the adaptation process between “new” and “old” Protestants has not been free of controversies. In this article, I deal with the analysis of the conflictive relationship between African Pentecostal Churches and the Catalan Protestant establishment. In order to do so, I explore the main transformations of the Catalan Protestant field (the phenomenon of reverse mission and above all the creation of ethnic churches) in recent times. The article is based on the fieldwork carried out among Protestant Churches in Catalonia between the years 2002 and 2006 and on ethnographic fieldwork carried out in an African church in Barcelona in 2004.A chegada (através do incremento de fluxos migratórios) de um número significativo de crentes à Catalunha alterou significativamente a configuração, expectativas de crescimento e lugar público da comunidade protestante daquela região. No entanto, o processo de adaptação entre “novos” e “velhos” protestantes não foi isento de controvérsia. Neste artigo, analiso a relação de conflito que se desenvolveu entre igrejas pentecostais africanas e o establishment protestante catalão. Para o fazer, exploro as principais transformações ocorridas no campo religioso protestante da Catalunha (o fenómeno de “missão reversa” e, sobretudo, a criação de “igrejas étnicas”) nos últimos tempos. Este artigo baseia-se em trabalho de campo etnográfico desenvolvido entre igrejas protestantes catalãs entre 2002 e 2006, e em particular numa igreja africana em Barcelona em 2004

    Geology of the Cerro Quema Au-Cu deposit (Azuero Peninsula, Panama)

    The Cerro Quema district, located on the Azuero Peninsula, Panama, is part of a large regional hydrothermal system controlled by regional faults striking broadly E-W, developed within the Río Quema Formation. This formation is composed of volcanic, sedimentary and volcano-sedimentary rocks indicating a submarine depositional environment, corresponding to the fore-arc basin of a Cretaceous–Paleogene volcanic arc. The structures observed in the area and their tectono-stratigraphic relationship with the surrounding formations suggest a compressive and/or transpressive tectonic regime, at least during Late Cretaceous–Oligocene times. The igneous rocks of the Río Quema Formation plot within the calc-alkaline field with trace and rare earth element (REE) patterns of volcanic arc affinity. This volcanic arc developed on the Caribbean large igneous province during subduction of the Farallon Plate. Mineralization consists of disseminations of pyrite and enargite as well as a stockwork of pyrite and barite with minor sphalerite, galena and chalcopyrite, hosted by a subaqueous dacitic lava dome of the Río Quema Formation. Gold is present as submicroscopic grains and associated with pyrite as invisible gold. A hydrothermal alteration pattern with a core of advanced argillic alteration (vuggy silica with alunite, dickite, pyrite and enargite) and an outer zone of argillic alteration (kaolinite, smectite and illite) has been observed. Supergene oxidation overprinted the hydrothermal alteration resulting in a thick cap of residual silica and iron oxides. The ore minerals, the alteration pattern and the tectono-volcanic environment of Cerro Quema are consistent with a high sulfidation epithermal system developed in the Azuero peninsula during pre-Oligocene time

    Stereoselective syntheses of the antihistaminic drug olopatadine and its E-isomer

    Get PDF
    Practical stereoselective synthetic routes to the antihistaminic drug olopatadine and its E-isomer have been developed, the key steps being a trans stereoselective Wittig olefination using a nonstabilized phosphorus ylide and a stereoselective Heck cyclization. The stereoselectivity of the Wittig reaction depends on both the phosphonium salt anion and the cation present in the base used to generate the ylide

    Subgrain rotation recrystallization during shearing: insights from full-field numerical simulations of halite polycrystals

    Get PDF
    We present, for the first time, results of full-field numerical simulations of subgrain rotation recrystallization of halite polycrystals during simple shear deformation. The series of simulations show how microstructures are controlled by the competition between (i) grain size reduction by creep by dislocation glide and (ii) intracrystalline recovery encompassing subgrain coarsening by coalescence through rotation and alignment of the lattices of neighboring subgrains. A strong grain size reduction develops in models without intracrystalline recovery, as a result of the formation of high-angle grain boundaries when local misorientations exceed 15°. The activation of subgrain coarsening associated with recovery decreases the stored strain energy and results in grains with low intracrystalline heterogeneities. However, this type of recrystallization does not significantly modify crystal preferred orientations. Lattice orientation and grain boundary maps reveal that this full-field modeling approach is able to successfully reproduce the evolution of dry halite microstructures from laboratory deformation experiments, thus opening new opportunities in this field of research. We demonstrate how the mean subgrain boundary misorientations can be used to estimate the strain accommodated by dislocation glide using a universal scaling exponent of about 2/3, as predicted by theoretical models. In addition, this strain gauge can be potentially applied to estimate the intensity of intracrystalline recovery, associated with temperature, using quantitative crystallographic analyses in areas with strain gradients

    The ephemeral development of C′ shear bands: A numerical modelling approach

    Full text link
    C′ shear bands are ubiquitous structures in shear zones but their development is poorly understood. Previous research has determined they mostly occur in rocks with a high mechanical strength contrast. Using numerical models of viscoplastic deformation, we studied the effect of the proportion of weak phase and the phase strength contrast on C′ shear band development during simple shearing to a finite strain of 18. We found that C′ shear bands form in models with ≥5% weak phase when there is a moderate or high phase strength contrast, and they occur in all models with weak phase proportions ≥15%. Contrary to previous research, we find that C′ shear bands form when layers of weak phase parallel to the shear zone boundary rotate forwards. This occurs due to mechanical instabilities that are a result of heterogeneous distributions of stress and strain rate. C′ shear bands form on planes of low strain rate and stress, and not in sites of maximum strain rate as has previously been suggested. C′ shear bands are ephemeral and they either rotate backwards to the C plane once they are inactive or rotate into the field of shortening and thicken to form X- and triangle-shaped structures

    Seismic Anisotropy of Temperate Ice in Polar Ice Sheets

    We present a series of simple shear numerical simulations of dynamic recrystallization of two‐phase nonlinear viscous materials that represent temperate ice. First, we investigate the effect of the presence of water on the resulting microstructures and, second, how water influences on P wave (Vp) and fast S wave (Vs) velocities. Regardless the water percentage, all simulations evolve from a random fabric to a vertical single maximum. For a purely solid aggregate, the highest Vp quickly aligns with the maximum c‐axis orientation. At the same time, the maximum c‐axis development reduces Vs in this orientation. When water is present, the developed maximum c‐axis orientation is less intense, which results in lower Vp and Vs. At high percentage of water, Vp does not align with the maximum c‐axis orientation. If the bulk modulus of ice is assumed for the water phase (i.e., implying that water is at high pressure), we find a remarkable decrease of Vs while Vp remains close to the value for purely solid ice. These results suggest that the decrease in Vs observed at the base of the ice sheets could be explained by the presence of water at elevated pressure, which would reside in isolated pockets at grain triple junctions. Under these conditions water would not favor sliding between ice grains. However, if we consider that deformation dominates over recrystallization, water pockets get continuously stretched, allowing water films to be located at grain boundaries. This configuration would modify and even overprint the maximum c‐axis‐dependent orientation and the magnitude of seismic anisotropy
