Abstract: Durant les últimes dècades els sistemes educatius europeus estan fent front a nombrosos reptes relacionats amb el tractament de la diversitat cultural i lingüística de l’alumnat. Per tal de poder afrontar aquesta diversitat es fa necessari impulsar plantejaments globals que s’adrecin al conjunt de la població amb la finalitat de construir una societat cohesionada. A l’article exposem algunes de les principals dificultats relatives a la formació inicial del professorat en quan a la gestió i al tractament de la diversitat lingüística i cultural, així com diferents projectes i enfocaments que pretenen establir noves directrius per a la seva formació competencial. In recent decades, European educational systems are facing many challenges related to the treatment of cultural and linguistic diversity. The need to address this diversity requires new approaches to education; this in turn requires changes in the way we prepare teachers for the new reality they face in their classrooms. In this article we highlight some of the major problems that initial teacher training has to address in order to enable teachers to deal effectively, respectfully, and fairly with students whose linguistic and cultural background is different from their own. We also present several models for teacher education from Europe and North America based on clearly identified teacher competences for linguistic and cultural diversity. Los sistemas educativos europeos están afrontando en las últimas décadas numerosos retos relacionados con el tratamiento de la diversidad cultural y lingüística. La necesidad de afrontar dicha diversidad requiere de planteamientos globales dirigidos al conjunto de la población en aras de construir una sociedad cohesionada lingüística, social y culturalmente. En este artículo exponemos algunos de los principales problemas que afectan a la formación inicial del profesorado por lo que se refiere a la gestión y el tratamiento de la diversidad cultural y lingüística así como diferentes proyectos y enfoques que justamente tienen por objetivo establecer su formación competencial.
La crisis de la psiquiatría espa ola durante el Tardofranquismo y la Transición. El caso del Institut Mental de la Santa Creu (1971-1986).
Josep María Comelles
Revista de la Asociación Espa?ola de Neuropsiquiatría , 1986,
Abstract: Se analiza el proceso de cambio seguido por una institución psiquiátrica espa ola entre 1971 y 1986 con el objeto de explorar las actitudes de los médicos y del personal sanitario en torno a la reforma de la estructura custodial del mismo. Se analiza la existencia de dos modelos de reforma en la institución que se corresponden con el dualismo existente actualmente en la profesión psiquiátrica en Espa a.

De la sangre al cosmos: Reflexiones sobre "el sentido de pertenencia" a partir de Antígona, Romeo y Julieta y Las aves
Serra, María N.;
En-claves del pensamiento , 2011,
Abstract: why is relevant the belonging question? why is pertinent asking how individuals feel themselves as a part of space of relationships? the idea of membership should be thinking in new ways and not only as a political affiliation, if we consider that we are living in a period in which national sovereignty has been frayed and national citizenship has broken down and fragmented into new processes. the theoretical refection developed from antigone, romeo and juliet and the birds was set up as a retrieval of past stories that allows us to create new categories and point of view to understand the ways in which individuals create emotional ties to their spaces of relations. belongings related to new referents and types of contact, practices and categorizations that in our time must be linked both global interconnections and new boundaries created by technologies.

Substitution of Nitrite Reductase of Thermosynechococcus elongatus BP-1 by the Homologous Gene of Phormidium laminosum  [PDF]
Maite Buxens, Juan L. Serra, María J. Llama
Advances in Microbiology (AiM) , 2013, DOI: 10.4236/aim.2013.36A009
Abstract: Even though the nitrate assimilation operon has been extensively studied in Phormidium laminosum, some aspects still remain unclear. The genetic manipulation of this cyanobacterium is problematic that hinders the elucidation of further aspects of nitrogen metabolism. To circumvent this, Thermosynechococcus elongatus BP-1 was selected as a surrogate host and its nirA gene was substituted by the homologous gene of P. laminosum. This process, based on Long Flanking Homology Polymerase Chain Reaction and the natural competence of T. elongatus BP-1, required an intermediate T. elongatus BP-1 ΔnirA::kat mutant, which carries a gene encoding a thermostable kanamycin nucleotidyl transferase in place of nirA_Te. In the presence of nirA_Pl, nirA defective mutants of T. elongatus BP-1 recovered the ability to grow with nitrate as the sole nitrogen source, and showed a phenotype similar to that observed in wild-type cells. The procedure could be useful to substitute other genes from T. elongatus BP-1 with the homologues from P. laminosum in order to study this particular operon. Furthermore, it may be used as a general tool to explore phenotypic changes due to the exchange of a single gene between cyanobacteria.

 

Effect of the Inorganic Nitrogen Source in the Expression of Nitrite Reductase (NirA) in Thermosynechococcus elongatus BP-1  [PDF]
Maite Buxens, María J. Llama, Juan L. Serra
Advances in Microbiology (AiM) , 2014, DOI: 10.4236/aim.2014.415115
Abstract:

Nitrite reductase (NirA, EC 1.7.7.1) from the thermophilic, unicellular, non-N2-fixing cyanobacte-rium Thermosynechococcus elongatus BP-1 has been cloned and expressed in Escherichia coli. Analysis by SDS-PAGE of the pure recombinant protein (His6NirA) showed two protein bands, one of 58 kDa (corresponding to the theoretical His6NirA molecular mass) and another of 44 kDa. Western blotting and mass spectrometry analyses confirmed that the 44 kDa protein resulted from proteolysis of the intact His6NirA, and suggested the existence, at the C-terminal domain of the 58 kDa form, of a region particularly sensible to proteolysis or accessible to proteases. A sample of both forms of His6NirA was used to obtain anti-NirA polyclonal antibodies. These antibodies were used to assess, by SDS-PAGE followed by Western blotting, the in vivo expression of NirA in wild-type cells of T. elongatus BP-1 growing in cultures with nitrate, nitrite or ammonium which were inoculated with cells grown with different nitrogen sources. These analyses revealed that protein bands corresponding to the complete (58 kDa) and truncated (44 kDa) forms of NirA can also be detected in solubilized cells. Moreover, the presence of each of these forms depended on the nitrogen source used to grow cells. Thus, expression of the complete NirA generally predominates in cells growing in medium with nitrate or nitrite. However, the truncated form prevails in cells grown in nitrate or nitrite and then transferred to medium with ammonium. The fact that the patterns of in vivo expression of NirA are different depending on the nitrogen source used possibly relies on a post-translational regulatory mechanism by proteolysis.

La aguja del Palau Güell
Moreno Lucas, Josep María
Informes de la Construccion , 1990,
Abstract: The beautiful needle which emerges from the roof of the PaIau Güell can be defined, according to the author of this article, as a cupola of classic conception with all its elements. It is composed of three essential parts: the cupola -of a single structure (and not double as had been said previously), made of four superimposed rings of small parabolic vaults, the lantern -with windows of a parabolic profile and other rhomboid apertures-, and the weathercock and lightening rod, a decorative and functional sculptural group made of iron, brass and copper. In this article, the constructive, static and formal aspects of the group and each one of the parts are analyzed in detail. An especially interesting aspect refers to the exterior facing of the needle, made of small pieces of glazed sandstone from the inside walls of the wood-burning time ovens, now abandoned. The nature of this facing, unstudied until now, is published for the first time in these pages. La bella aguja que emerge de la azotea del PaIau Güell puede definirse, según el autor de este artículo, como una cúpula de concepción clásica con todos sus elementos. Se compone de tres partes esenciales: la cúpula —de estructura única (no doble como se había dicho hasta ahora), formada por cuatro anillos superpuestos de peque as bóvedas parabólicas—, la linterna —con ventanas de perfil parabólico y otras aberturas romboidales—, y la veleta-pararrayos, un conjunto escultórico decorativo y funcional hecho de hierro, latón y cobre. En el artículo se analizan con detalle los aspectos constructivos, estáticos y formales del conjunto y cada una de sus partes. Un aspecto especialmente interesante es lo referente al revestimiento exterior de la aguja, hecho con peque os fragmentos de piedra arenisca vitrificada procedente de las caras interiores de los antiguos hornos de cal de le a amortizados. La naturaleza de este revestimiento, hasta ahora no estudiada, se publica por primera vez en estas páginas.
El directo: análisis de una situación informativa privilegiada (o "carpe diem")
Lic. Josep María Blanco
Revista Latina de Comunicación Social , 1999,
Abstract: el momento, eso es! Cuando se oprime el interruptor de un televisor y se atrapa el mando a distancia se aspira a satisfacer alguna necesidad o a dar respuesta incluso a la propia ausencia de necesidades. Y es eso malo? De ninguna manera; se trata de un intento de emplear, de aprovechar el tiempo, porqué no, para distraerse, para informarse, para aprender o simplemente para llenar el vacío sonoro que en el hogar, por ejemplo, acentúa la sensación de soledad.
