No és la meva competència intercultural, soc jo.’ La identitat intercultural del professorat de llengües estrangeres en formació

This article examines the intercultural identity of pre-service foreign language teachers to determine whether they are aware of their intercultural stance and that of others, and whether they portray an identifiable emergent professional persona in relation to interculturality. The ultimate goal of this study is to identify common traits on which to focus future teacher training. The results show that these prospective teachers display an incipient intercultural identity characterised by a tendency to avoid agency and a certain shortage of intercultural knowledge, yet they are notably concerned about their professional image and their responsibility in work environmentsEste artículo indaga en la identidad intercultural del profesorado de lenguas extranjeras en formación para averiguar si es consciente de su postura intercultural y de la de otros, y si presenta una imagen profesional emergente reconocible en relación con la interculturalidad. El objetivo final de este estudio es identificar rasgos comunes en los que podría centrarse la formación del profesorado. Los resultados demuestran que este futuro profesorado muestra una identidad intercultural incipiente caracterizada por su tendencia a evitar la intervención y por una cierta falta de conocimiento intercultural, aunque está notablemente preocupado por su imagen profesional y su responsabilidad en contextos laboralesAquest article indaga en la identitat intercultural del professorat de llengües estrangeres en formació per esbrinar si és conscient de la seva postura intercultural i de la dels altres, i si presenta una imatge professional emergent recognoscible en relació amb la interculturalitat.

A Genome-Wide Analysis of Genetic Diversity inTrypanosoma cruzi Intergenic Regions

Background Trypanosoma cruzi is the causal agent of Chagas Disease. Recently, the genomes of representative strains from two major evolutionary lineages were sequenced, allowing the construction of a detailed genetic diversity map for this important parasite. However this map is focused on coding regions of the genome, leaving a vast space of regulatory regions uncharacterized in terms of their evolutionary conservation and/or divergence. Methodology Using data from the hybrid CL Brener and Sylvio X10 genomes (from the TcVI and TcI Discrete Typing Units, respectively), we identified intergenic regions that share a common evolutionary ancestry, and are present in both CL Brener haplotypes (TcII-like and TcIII-like) and in the TcI genome; as well as intergenic regions that were conserved in only two of the three genomes/haplotypes analyzed. The genetic diversity in these regions was characterized in terms of the accumulation of indels and nucleotide changes. Principal Findings Based on this analysis we have identified i) a core of highly conserved intergenic regions, which remained essentially unchanged in independently evolving lineages; ii) intergenic regions that show high diversity in spite of still retaining their corresponding upstream and downstream coding sequences; iii) a number of defined sequence motifs that are shared by a number of unrelated intergenic regions. A fraction of indels explains the diversification of some intergenic regions by the expansion/contraction of microsatellite-like repeats.Fil: Panunzi, Leonardo Gabriel.

Assessing the identity of the variety "Pedro Giménez" grown in Argentina through the use of microsatellite markers.

'Pedro Giménez' es una variedad criolla blanca cultivada en Argentina, principalmente en las provincias de Mendoza y San Juan, siendo la variedad con la mayor superficie entre las uvas blancas de vinificación. Su origen es desconocido, como también su relación con la variedad española 'Pedro Ximénez', cultivada especialmente en la región de Jerez, España. En trabajos previos se ha probado que la mayoría de las variedades criollas existentes en América se habrían originado del cruzamiento de 'Moscatel de Alejandría' x 'Criolla Chica'. El presente trabajo tuvo como objetivos comparar las variedades 'Pedro Giménez' y 'Pedro Ximénez', y establecer relaciones de parentesco con 'Moscatel de Alejandría' y 'Criolla Chica'. Se utilizaron 18 loci microsatélites nucleares y 3 loci microsatélites de cloroplasto. 'Pedro Giménez' compartió sólo el 38% de los alelos con 'Pedro Ximénez', por lo que se pudo inferir que se trata de variedades diferentes. En todos los loci polimórficos nucleares analizados 'Pedro Giménez' compartió uno de los alelos con 'Moscatel de Alejandría' y el otro con 'Criolla Chica'. Estos datos, junto con el resultado del análisis de SSR de cloroplastos, avalan la hipótesis que, como muchas de las variedades criollas, 'Pedro Giménez' sería fruto del cruzamiento entre estos dos progenitores, siendo 'Criolla Chica' probablemente el progenitor materno.´Pedro Giménez´ is a white criolla variety cropped in Argentina, mainly in Mendoza and San Juan, being the most planted white variety destined for wine making in the country. Its origin remains unknown, as well as its relationship with Spanish variety ´Pedro Ximénez´, mostly grown in Jerez, Spain. Previous works have probed that most of Criollas varieties existing in America at the moment, are the offspring of ´Muscat of Alexandria´ x ´Criolla Chica´. The aim of the present work was to compare ´Pedro Giménez´ with the Spanish variety ´Pedro Ximénez´, and to establish its degree of relatedness to ´Muscat of Alexandria´ and ´Criolla Chica´. Therefore we used a set of 18 nuclear SSR loci and 3 chloroplast SSR loci. ´Pedro Giménez´ shared only 38% of the alleles under analysis with ´Pedro Ximénez´, indicating that they are indeed two different varieties. In all 18 polymorphic nuclear SSR loci ´Pedro Giménez´ shared 50% of its alleles with ´Muscat of Alexandria´, while the other 50% of the alleles present in ´Pedro Giménez´ were also present in ´Criolla Chica´. This data, along with those from the chloroplast SSR analysis, strongly suggest that ´Pedro Giménez´ is the progeny of ´Muscat of Alexandria´ x ´Criolla Chica´, being the latest one the most likely female progenitor.Fil: Duran, Martin Francisco.

Measuring entanglement of photons produced by a pulsed source

A pulsed source of entangled photons is desirable for some applications. Yet, such a source has intrinsic problems arising from the simultaneous arrival of the signal and noise photons to the detectors. These problems are analyzed and practical methods to calculate the number of accidental (or spurious) coincidences are described in detail, and experimentally checked, for the different regimes of interest. The results are useful not only to measure entanglement, but to all the situations where extracting the number of valid coincidences from noisy data is required. As an example of the use of those methods, we present the time-resolved measurement of the Concurrence of the field produced by spontaneous parametric down conversion with pump pulses of duration in the ns-range at a repetition of kHz. The predicted discontinuous evolution of the entanglement at the edges of the pump pulse is observed.Comment: 9 pages, 10 or 7 figures (one of the figures includes 4), 28 Refernce
