Post-adopció i resiliència: l'ajust psicosocial i vivència de l'adopció en infants adoptats internacionalment

Antecedents. Cada cop són més els nens i nenes adoptats internacionalment que creixen en la nostra societat, i el seu ajust psicosocial s’ha convertit en un assumpte d’especial interès i rellevància. Objectius. Estudiar l'ajust psicosocial i la vivència de l'adopció en els infants adoptats internacionalment. Els objectius específics són: 1) estudiar els nivells d’adaptació personal i social en nens i nenes adoptats/des internacionalment, en comparació amb els estàndards de la població normativa; 2) estudiar la vivència de l’adopció en nens i nenes adoptats internacionalment i la percepció que mares i pares en tenen al respecte; 3) analitzar el paper de las variables estrés i estratègies d’afrontament en l’ajust psicosocial dels infants adoptats. Material i Mètode. La mostra està formada per 103 infants adoptats a l’estranger, d’entre 8 i 12 anys, i els seus respectius pares i mares. Els participants completaren les següents proves: BASC (Behavior Assessment System for Children (BASC; Reynolds & Kamphaus, 1992), Qüestionari de punts forts i febles (SDQ; Goodman, 1997, 1999), Escala de la vivència adoptiva (Reinoso, 2008), Kidcope (Spirito, Stara y Williams, 1988). En realitzen anàlisis estadístics de tipus descriptiu, comparatiu, correlacional i exploratori. Resultats. La majoria dels menors adoptats internacionalment presenta bons nivells de funcionament, si bé un 25% d’ells presenta dificultats adaptatives bàsiques. En general s’observa un elevat nivell de convergència en la visió de l’experiència adoptiva entre nens/es i mares i pares. Els infants puntuen més alt en identitat cultural i més baix en discriminació percebuda que els seus pares/mares. Principalment esmenten problemes interpersonals de relació i de salut, malalties i accidents i utilitzen predominantment estratègies d’afrontament aproximatives. Els estressors vinculats amb l’experiència adoptiva són escassament mencionats. Conclusions. L’especificitat de la condició adoptiva requereix d’intervencions ajustades a la realitat d’aquests les necessitats d’aquests nens i les seves families.

Understanding the development of the ESDP: Perspectives and insights from historical institutionalism and theories of learning

How can we best understand the emergence of the European Security and Defence Policy (ESDP)? This paper applies the theories of historical institutionalism and experiential learning to offer a dynamic conceptualisation of moves towards an ESDP which highlights some of the causal factors that a more temporally-restricted analysis would miss. It firstly shows how the institutional and functional expansion of European Political Cooperation (EPC) over the course of the 1970s and 80s gave rise to a context in which the development of a security and defence dimension came to be viewed as more logical and even necessary. It then goes on to analyse some of the external factors (in the form of actors, events and institutions) that further pushed in this direction and proved to influence the policy’s subsequent evolution. The paper is therefore intended to act as a first-step to understanding the ESDP’s development from this perspective.

El Memorial de Barcelona a Archer Milton Huntington, el fundador de la Hispanic Society of America, y a su esposa, la escultora, Anna Hyatt Huntington.

Barcelona en 1954 se anticipo a todos los homenajes, dedicando a Archer Milton Huntington (New York, 1870- Bathel, Connecticut, 1955) un monumento en reconocimiento a su excepcional figura como coleccionista e hispanófilo y también a su esposa, Anna Vaughn Hyatt Huntington (Cambridge, 1876 - California, 1973), excelente escultora que generosamente secundo los propósitos filo hispanos de su consorte. De esta manera Barcelona quería dejar constancia de su devoción y tributo a este reconocido coleccionista y filántropo americano que ayudo a vencer el llamado "Paradigma Prescott", historiador que había defendido las tesis sobre la leyenda negra española. A la vez que se reconocía que Archer M. Huntington ocupaba un lugar preeminente en la línea del hispanismo americano conjuntamente con los nombres de George Ticknor (1791 -1871), Washington Irving (1783-1859) y Henry Longfellow (1807-1882).

The Monument Erected in Barcelona in 1954 in Honor of Archer Milton Huntington, the Founder of The Hispanic Society of America, and His Wife, Anna Hyatt Huntington, the Eminent Sculptress.

It was in 1954 that Barcelona became the first city to pay tribute to Archer Milton Huntington (New York, 1870 - Bathel, Connecticut, 1955), by erecting a monument to the memory of this outstanding collector and Hispanist, and to hiswife, Anna Vaughn Hyatt Huntington (Cambridge, 1876 - California, 1973). An excellent sculptor, Anna Hyatt Huntington was also unstinting in her support of her husband¿s Hispanic interest. The monument was Barcelona's way of recognizing and paying tribute to this greatly respected American collector and philanthropist. Huntington played a major role in refuting "Prescott's Paradigm", named after the historian whose work on Spain did much to further the Black Legend.3 Moreover, Huntington occupied an important place in American Hispanic Studies, along with such other outstanding names as George Ticknor (Boston, 1791 - 1871), Washington Irving (New York, 1783 - 1859) and Henry Longfellow (1807 - 1882).

Inhibition of glutathione efflux in the perfused rat liver and isolated hepatocytes by organic anions and bilirubin. Kinetics, sidedness, and molecular forms.

Using isolated, in situ, single-pass perfused rat livers, incubations of freshly isolated hepatocytes, and sinusoidal membrane-enriched vesicles, we and others have shown the saturability of transport (efflux) of hepatic glutathione (GSH). These observations have implicated a carrier mechanism. Our present studies were designed to provide further evidence in support of a carrier mechanism for hepatic GSH efflux by demonstrating competition by liver-specific ligands which are taken up by hepatocytes. Perfusing livers with different substances, we found that: (a) sulfobromophthalein-GSH (BSP-GSH) had a dose-dependent and fully reversible inhibitory effect on GSH efflux, while GSH alone did not have any effect; (b) taurocholate had no inhibitory effect; (c) all of the organic anions studied, i.e., BSP, rose bengal, indocyanine green, and unconjugated bilirubin (UCB), manifested potent, dose-dependent inhibitory effects, with absence of toxic effects and complete reversibility of inhibition in the case of UCB. The inhibitory effects of UCB could be overcome partially by raising (CoCl2-induced) hepatic GSH concentration. Because of the physiological importance of UCB, we conducted a detailed study of its inhibitory kinetics in the isolated hepatocyte model in the range of circulating concentrations of UCB. Studies with Cl- -free media, to inhibit the uptake of UCB by hepatocytes, showed that the inhibition of GSH efflux by UCB is apparently from inside the cell. This point was confirmed by showing that the inhibition is overcome only when bilirubin-loaded cells are cleared of bilirubin (incubation with 5% bovine serum albumin). Using Gunn rat hepatocytes and purified bilirubin mono- and diglucuronides, we found that both UCB and glucuronide forms of bilirubin inhibit GSH efflux in a dose-dependent manner. We conclude that the organic anions, although taken up by a mechanism independent of GSH, may competitively inhibit the carrier for GSH efflux from inside the hepatocyte.

Sedimentation of pairs of hydrodynamically interacting semiflexible filaments

We describe the effect of hydrodynamic interactions in the sedimentation of a pair of inextensible semiflexible filaments under a uniform constant force at low Reynolds numbers. We have analyzed the different regimes and the morphology of such polymers in simple geometries, which allow us to highlight the peculiarities of the interplay between elastic and hydrodynamic stresses. Cooperative and symmetry breaking effects associated to the geometry of the fibers gives rise to characteristic motion which give them distinct properties from rigid and elastic filaments.

LRCW.NET: A web site with a virtual laboratory for the study of coarse and cooking wares in the Late Antique Mediterranean

This contribution presents the LRCW.net a website with a virtual laboratory intranet devoted to the study of coarse and cooking wares in the late Antique Mediterranean. It is designed as a public website with a virtual laboratory intranet. There, all institutions and researchers interested in the subject can work together towards a specific purpose such as the creation of an on-line ‘encyclopedia’ for these categories of ceramics. The LRCW.net website and the associated virtual laboratory are just a small part of a wider initiative that aims to create an on-line Encyclopedia for Ancient Ceramics in the Mediterranean.

Late Roman amphorae in the eastern Tarraconensis. Some chronological and quantitative approaches

Since the classic study of Simon J. Keay published in 1984, knowledge of late Roman amphorae has progressed markedly, thanks to scholars such as Michel Bonifay and Paul Reynolds, amongst others. The area studied by Keay was Catalonia, the ancient Eastern Tarraconensis. The overview here offered for this same region reveals the central role played by African imports in late Antique times, with a minor presence of the Eastern-Mediterranean and South-Hispanic (both Baetican and Lusitanian) productions. Progress in research in the last 25 years has been centred on a series of new and well-dated contexts: the data they have yielded has clarified more precisely the chronology and the proportions of the different imports. On occasion a quantitative approach may even be applied. At the same time the relationship between town and country with respect to the late Roman amphorae is proving of interest and providing results of significance.
