Un mercado beneficial: la mercantilización de beneficios eclesiásticos en Castilla y Portugal

Thanks to some classical and recent studies, we know the main features of the huge structure that served as financial support to the secular clergy in the Ancien Régime, the system of benefices. However, almost nothing has been said yet about the process that made possible the conformation around these benefices of a market of transnational nature, controlled by the Holy See, to which outflowed a great amount of capital from the Iberian Peninsula. So these pages are intended to sketch a research line, that of the commodification of ecclesiastical benefices, virtually unattended so far. It will be examined the instruments of this market, its practices and the comparative evolution of the phenomenon in cathedrals of Castile and Portugal.

U-Pb geochronology and Nd isotope contributions to the interpretation of a peculiar ring massif: the Santa Eulália plutonic complex (SW Iberia, Portugal)

The Santa Eulalia plutonic complex (SEPC) is a late-Variscan granitic body placed in the Ossa-Morena Zone. The host rocks of the complex belong to metamorphic formations from Proterozoic to Lower Paleozoic. The SEPC is a ring massif (ca. 400 km2 area) composed by two main granitic facies with different colours and textures. From the rim to the core, there is (i) a peripheral pink medium- to coarse-grained granite (G0 group) involving large elongated masses of mafic and intermediate rocks, from gabbros to granodiorites (M group), and (ii) a central gray medium-grained granite (G1 group). The mafic to intermediate rocks (M group) are metaluminous and show wide compositions: 3.34–13.51 wt% MgO; 0.70–7.20 ppm Th; 0.84–1.06 (Eu/Eu*)N (Eu* calculated between Sm and Tb); 0.23–0.97 (Nb/Nb*)N (Nb* calculated between Th and La). Although involving the M-type bodies and forming the outer ring, the G0 granites are the most differentiated magmatic rocks of the SEPC, with a transitional character between metaluminous and peraluminous: 0.00–0.62 wt% MgO; 15.00–56.00 ppm Th; and 0.19–0.42 (Eu/Eu*)N ; 0.08–0.19 (Nb/Nb*)N [1][2]. The G1 group is composed by monzonitic granites with a dominant peraluminous character and represents the most homogeneous compositional group of the SEPC: 0.65–1.02 wt% MgO; 13.00–16.95 ppm Th; 0.57–0.70 (Eu/Eu*)N ; 0.14–0.16 (Nb/Nb*)N . According to the SiO2 vs. (Na2O+K2O–CaO) relationships, the M and G1 groups predominantly fall in the calc-alkaline field, while the G0 group is essencially alkali-calcic; on the basis of the SiO2 vs. FeOt/(FeOt+MgO) correlation, SEPC should be considered as a magnesian plutonic association [3]. New geochronological data (U-Pb on zircons) slightly correct the age of the SEPC, previously obtained by other methods (290 Ma, [4]). They provide ages of 306  2 Ma for the M group, 305  6 Ma for the G1 group, and 301  4 Ma for the G0 group, which confirm the late-Variscan character of the SEPC, indicating however a faintly older emplacement, during the Upper Carboniferous. Recent whole-rock isotopic data show that the Rb-Sr system suffered significant post-magmatic disturbance, but reveal a consistent set of Sm-Nd results valuable in the approach to the magmatic sources of this massif: M group (2.9 < Ndi < +1.8); G1 group (5.8 < Ndi < 4.6); G0 group (2.2 < Ndi < 0.8). These geochemical data suggest a petrogenetic model for the SEPC explained by a magmatic event developed in two stages. Initially, magmas derived from long-term depleted mantle sources (Ndi < +1.8 in M group) were extracted to the crust promoting its partial melting and extensive mixing and/or AFC magmatic evolution, thereby generating the G1 granites (Ndi < 4.6). Subsequently, a later extraction of similar primary magmas in the same place or nearby, could have caused partial melting of some intermediate facies (e.g. diorites) of the M group, followed by magmatic differentiation processes, mainly fractional crystallization, able to produce residual liquids compositionally close to the G0 granites (Ndi < 0.8). The kinetic energy associated with the structurally controlled (cauldron subsidence type?) motion of the G0 liquids to the periphery, would have been strong enough to drag up M group blocks as those occurring inside the G0 granitic ring.

On the spatial convergence of (un)employment in Portugal

Regarding the EU policies of territorial cohesion is common to assume that, having the same been successful (in Portugal), regional disparities decreased. The purpose of this article is to assess the veracity of this allegation, for that considering the values of employment and unemployment rates by municipalities, determined in the last two censuses held in Portugal, i.e. 2001 and 2011. In doing so, spatial econometric techniques are used, namely local indicators of spatial association and spatial clusters, in order to better understand the eventual process of spatial convergence that may have occurred in Portugal in that period. The results point towards a spatial convergence of employment rates (both in total and by genres) and also of female unemployment rates but a spatial divergence of male unemployment rates.

O género sonata em Portugal: subsídios para o estudo do repertório português para tecla de 1750 a 1807

O repertório português para instrumentos de tecla da segunda metade do século XVIII encontra-se disperso em bibliotecas e arquivos, em Portugal e no estrangeiro, essencialmente sob a forma de manuscrito. Neste repertório, a sonata emerge como um género musical de grande importância. De facto, as duas coleções de sonatas publicadas na época constituem as únicas obras para instrumentos de tecla impressas em Portugal durante todo esse século. O objetivo deste trabalho é realizar um inventário do repertório português composto para instrumentos de tecla durante o período acima descrito, focando a respectiva descrição formal e as características composicionais das sonatas em geral, e na produção de cada compositor português em particular, bem como as suas biografias e perfis. De forma a estudar a sonata portuguesa e o seu desenvolvimento no período compreendido entre 1750–1807, foi realizado um levantamento das obras portuguesas existentes para instrumentos de tecla deste período. Este levantamento foi acompanhado por pesquisas biográficas sobre cada compositor e por uma abordagem analítica baseada na Teoria da Sonata de James Hepokoski e Warren Darcy. A divisão deste período em dois subperíodos demonstra variações significativas na evolução da sonata portuguesa. O estudo deste repertório demonstra que a sonata é o género musical predominante e define o modelo da sonata portuguesa deste período, para além de caracterizar o desenvolvimento da sonata em Portugal em paralelo com o desenvolvimento deste género musical em Itália e Espanha; ABSTRACT: The Sonata Genre in Portugal: Contributions for the Study of the Portuguese Keyboard Repertory from 1750 to 1807 The extant Portuguese repertory of the second half of the eighteenth century for keyboard instruments is dispersed in libraries and archives, in Portugal and abroad, mainly in manuscript form. In that repertory, the sonata emerges as a genre of great importance. Indeed, the two collections of sonatas published at the time are the only works for keyboard instruments printed in Portugal throughout the entire century. The aim of the present work is to make an inventory of the Portuguese repertory written for keyboard instruments during the above-mentioned period, with a focus on its formal description and the compositional characteristics of the sonatas in general and in the production of each Portuguese composer in particular, in addition to the biographies and profiles of the latter. In order to study the Portuguese sonata and its development in the period comprised between 1750–1807, a survey of the existing Portuguese works for keyboard instruments from that period was done. This survey was followed by a research on the biography of each composer and an analytic approach based on the Sonata Theory by James Hepokoski and Warren Darcy. Dividing this period in two sub periods showed significant variations on the evolution of the Portuguese sonata. The study of this repertory shows that the sonata is the predominant musical genre within it and identifies the Portuguese sonata model of this period, besides characterizing the development of the sonata in Portugal in parallel with the development of the same genre in Italy and Spain.

The Impacts of Climate Change on Irrigated Agriculture in Southern Portugal

Climate change projections point to increasing air temperature and reduced precipitation in southern Portugal, which would affect farming systems. This study aims to assess the impacts of climate change on irrigated agriculture in southern Portugal. These impacts were assessed by combining climate model data with a soil water balance model and a numerical model for the design of irrigation systems. Meteorological data from two weather stations were used along with three climate models (HadRM3P, HIRHAMh and HIRHAMhh; 2071–2100). The crop rotations studied included sugar beet–maize–tomato–wheat and sunflower–wheat–barley. Two adaptation measures were considered: (i) maintaining the current crop varieties; (ii) using new crop varieties. The results from the considered climate change scenarios indicated that the impacts of climate change on irrigation requirements depend on the adopted adaptation measures. On average, the seasonal irrigation requirements increased by 13–70% when new crop varieties were used and by −13 to 7% when the current crop varieties were maintained. The impacts of climate change on irrigation system design were considerable, with the design flow rate increasing by 5–24%.
