En las elecciones municipales celebradas en el año 2003 hizo eclosión en Cataluña una formación islamófoba que reclamaba un “mejor control de la inmigración”: la Plataforma per Catalunya [PxC]. Con sede central en Vic (Barcelona), había sido constituida un año antes por Josep Anglada, un antiguo militante del partido ultraderechista Fuerza Nueva. Este ensayo analiza la evolución de la PxC desde sus orígenes hasta febrero de 2009 (cuando concluye la redacción del texto) y expone cómo la PxC configura una oferta nueva inserta en un proceso de cambio del sistema político catalán. Su caso es llamativo en la medida que constituye el único de un nacional-populismo desarrollado en España que cuenta con una presencia institucional significativa.

Si bien los estudios sobre las coaliciones de gobierno constituyeron uno de los campos más estudiado en la literatura en ciencias políticas, merece precisar que la gran mayoría de los estudios sufren de un eurocentrismo al centrarse esencialmente sobre los sistemas parlamentarios de gobierno. Al ubicarse en la órbita del debate en boga sobre presidencialismo vs. parlamentarismo, los gobiernos de coaliciones fueron ampliamente sub-estudiados en los presidencialismos. Los pocos trabajos que se publicaron, se limitaron generalmente al análisis de los repartos de las parcelas de poder, o las disoluciones de las coaliciones. Este trabajo se propone asimismo realizar una actualización de las teorías de las coaliciones aplicándolas a los presidencialismos latinoamericanos. Nos centralizaremos sobre las experiencias conosurianas, y demostraremos asimismo que lejos de ser un fenómeno “accidental”, esas coaliciones incidieron sobre la gobernanza y el qué hacer político, y condujeron a un reordenamiento sustantivo de los sistemas partidarios.

A series of circumstances which converge in a little valley in the province of Girona, result in a peculiar type of morphogenetic evolution and a quite singular mechanical instability of its buttons. Very recent tectonic movements as well as dissolution phenomena of its subsoil due to pressurized underground water have played an important role in the morphogenesis. Such conditions have resulted in a fast morphological evolution which a progressive lowering of the valley floor as well as peculiar morphological features which favour the existence of numerous pits caused by sudden collapses distributed in altitude and time

In the southeastern Ebro Foreland Basin, the marine deposits of Lutetian and Bartonian age show excellent outcrop conditions, with a great lateral and horizontal continuity of lithostratigraphic units. In addition, the rich fossil record -mainly larger foraminifers-, provides biostratigraphic data of regional relevance for the whole Paleogene Pyrenean Basin, that can be used for the Middle Eocene biocorrelation of the western Tethys. This contribution is a sedimentary and biostratigraphic synthesis of the basic outcrops and sections of the Lutetian andBartonian marine and transitional deposits in the southeastern sector of the Ebro Foreland Basin.

The stratigraphic basis of this work has allowed the use of larger foraminifers in the biostratigraphic characterisation of the new Shallow Benthic Zones (SBZ). This part of the volume presents a description of the sedimentary cycles formed by the transgressive-regressive systems of the Lutetian and Bartonian in the southeastern sector of the Ebro Foreland Basin. Concerning the Lutetian deposits studied in the Amer-Vic and Empordà areas, four sedimentary cycles have been characterised. The first and second are found within the Tavertet/Girona Limestone Formation (Reguant, 1967; Pallí, 1972), while the third and fourth cycles cover the Coll de Malla Marl Formation (Clavell et al., 1970), the Bracons Formation (Gich, 1969, 1972), the Banyoles Marl Formation (Almela and Ríos, 1943), and the Bellmunt Formation (Gich, 1969, 1972). In the Bartonian deposits studied in the Igualada area, two transgressive-regressive sedimentary cycles have been characterised in the Collbàs Formation (Ferrer, 1971), the Igualada Formation (Ferrer, 1971), and the Tossa Formation (Ferrer, 1971). The Shallow Benthic Zones (SBZs) recognised within the Lutetian are the following: SBZ 13, from the Early Lutetian, in the transgressive system of the first cycle; SBZ 14, from the Middle Lutetian, in the second cycle and the lower part of the transgressive system of the third cycle; SBZ 15, from the Middle Lutetian, in the remaining parts of the third system; SBZ 16, from the Late Lutetian, throughout the fourth cycle. The association of larger foraminifers in the first and second cycles of the Bartonian in the Igualada area has been used as the basis for the definition of SBZs 17 and 18 recognised in the Bartonian of the western Tethys.

The decapod burrow Spongeliomorpha sudolica occurs associated with transgressive firmgrounds in the transition between Aragonian continental red beds and Langhian marine units in some of the inner sectors of the Vallès-Penedès Basin. This ichnospecies designates branching burrow systems with scratch marks in the walls produced by marine crustacean decapods. The occurrence of Spongeliomorpha represents an example of theGlossifungites ichnofacies. The several horizons where the traces are found are intercalated with continental red beds a few meters below the main transgressive surface, which is overlain by fossiliferous marine sandstones. The Spongeliomorpha-bioturbated layers record short, high frequency marine flooding surfaces that may be related either to actual sea-level changes or to variations in tectonic subsidence or sediment input. In any case, these flooding events punctuated the early phases of the Langhian transgression in the basin.

El objetivo de este artículo es poner en relación los «factores de éxito» de la implementación de la reforma europea de la educación superior, que se mencionan en el informe de la European University Association (EUA) (2005), con los resultados de un estudio de caso llevado a término en una universidad catalana (Masjuan y otros, 2006). Se pretende analizar a un nivel más próximo los particularismos de una institución concreta y aproximarnos a los mecanismos que pueden hacer avanzar la reforma u obstacularizarla. Por razones de espacio, se tienen en cuenta en este artículo solamente tres factores de éxito: la relación con otras reformas de enseñanza superior; el equilibrio correcto entre regulación y coordinación de ámbito estatal y autonomía institucional, y el soporte financiero estatal.

In recent years, contradictory reports about whether or not an unconformity exists at the base of the Upper Ordovician succession of the Pyrenees have been made. In the Cerdanya area (Central Pyrenees), good outcrop evidence for this unconformity is displayed at the base of the Rabassa conglomerates. In this area, the Upper Ordovician rocks overlie a tilted Cambro-Ordovician sequence, displaying an angular unconformity and indicating a break in the stratigraphic series. Moreover, the existence of such an unconformity is supported by the distribution of Variscan minor structures, suggesting that the Cambro-Ordovician and the Upper Ordovician strata initially had different orientations before the main Variscan folding.

The evaporite unit (the Lécera Formation), which was formed at the Triassic¿Liassic boundary in the Aragonian Branch of the Iberian Chain, was studied at the 01 Alacón borehole (Alacón village, Teruel province), where it is mainly constituted by a thick (>e and reflect deeper water settings, whereas in the upper part they correspond to shallower water settings. The evaporite sedimentation mainly occurred in a subsiding coastal basin of the salina or lagoon type. In this setting, the subaqueous precipitation of the carbonate and gypsum lithofacies was followed, in each cycle, by the interstitial growth of anhydrite in exposed conditions. As a whole, the evaporite succession reflects an infilling process. The conversion into anhydrite of the selenitic gypsum -probably also of the rest of depositional gypsum lithofaciesstarted under synsedimentary conditions and followed during shallow to moderate burial diagenesis.

En este trabajo presentamos los resultados de una escala de actitudes en una muestra de 66 profesores en ejercicio y 74 profesores en educación infantil y primaria. No encontramos diferencias por géneros, aunque sí una mejoría en aquellos alumnos que estudiaron estadística previamente. La actitud es algo mejor en los profesores en ejercicio, aunque tiende a empeorar con el uso o la enseñanza de la estadística. Pensamos que estos resultados sugieren la dificultad que tiene dicha materia para los profesores y la necesidad de apoyo que éstos deberían recibir desde los departamentos de didáctica y tas facultades de educación.

Se ha realizado el estudio sistemático de los nummulítidos pertenecientes a los géneros Nummulites y Assilina del intervalo Paleoceno Superior - Eoceno Inferior de la Cuenca Pirenaica, a partir de muestras procedentes principalmente del sector meridional de la cuenca. Los taxones descritos se han comparado con especímenes procedentes de otras cuencas de la Mesogea: Alpes suizos (Schlieren- y Gumigelflysch) y austríacos (unidades alóctonas helvéticas), norte de Italia (Verona y Vicenza), plataformas marinas adriáticas (Eslovenia y Croacia), península de Crimea (Ucrania), Cuenca de Haymana (Anatolia central, Turquía), y Salt Range (Pakistán). Se han descrito 98 taxones de nummuiítidos -entre especies y subespecies-, de los cuales: - 66 taxones del género Nummulites, pertenecientes a los grupos de N. perforatus, N. partschi, N. rotularius, N. minewensis, N. globulus, N. laevigatus, N. distans, N. heberti y N. spirectypus. - 32 taxones del género Assilina, pertenecientes a los gmpos de A. spira, A. exponens, A. subgranulosa, A. ammonea, A. canalijera y A. alpina. En este trabajo -y siguiendo las consideraciones de Loeblich y Tappan (1987)- Assilina integra las denominaciones gen6ricas tradicionales de Assilina y Operculina.
