La inclusió de l'alumnat nouvingut mitjançant la pràctica d'activitats físicoesportives extraescolars

Una de les conseqüències directes del fenomen de la diversitat cultural és l'elevat nombre d'alumnat nouvingut als centres educatius. Davant d'aquest fet, les activitats físicoesportives poden esdevenir una bona estratègia per afrontar amb eficàcia el repte d'assolir una educació inclusiva i per a tothom. Aquest article presenta un estudi dut a terme als centres educatius reconeguts oficialment com a centres amb aula d'acollida. Concretament, mostra els resultats obtinguts en l'aplicació d'un qüestionari complimentat pels educadors (professorat, mestres i altres agents educatius) amb la intenció de copsar el valor inclusiu de les activitats físicoesportives dutes a terme en horari no-lectiu.

Open Educational Resources: an opportunity for virtual learning institutions

The Universitat Oberta de Catalunya (UOC, Open University of Catalonia) is involved inseveral research projects and educational activities related to the use of Open Educational Resources (OER). Some of the discussed issues in the concept of OER are research issues which are being tackled in two EC projects (OLCOS and SELF). Besides the research part, the UOC aims at developing a virtual centre for analysing and promoting the concept of OERin Europe in the sector of Higher and Further Education. The objectives are to makeinformation and learning services available to provide university management staff,eLearning support centres, faculty and learners with practical information required to create, share and re-use such interoperable digital content, tools and licensing schemes. In the realisation of these objectives, the main activities are the following: to provide organisationaland individual e-learning end-users with orientation; to develop perspectives and useful recommendations in the form of a medium-term Roadmap 2010 for OER in Higher and Further Education in Europe; to offer practical information and support services about how to create, share and re-use open educational content by means of tutorials, guidelines, best practices, and specimen of exemplary open e-learning content; to establish a larger group ofcommitted experts throughout Europe and other continents who not only share theirexpertise but also steer networking, workshops, and clustering efforts; and to foster and support a community of practice in open e-learning content know-how and experiences.

Re-writing and Its Pedagogical Value: A Case Study

Tenint en compte el temps i la energia que els mestres i professors dediquen a la correcció de redaccions i produccions escrites i el poc efecte que aquestes semblen tenir en altres produccions dels aprenents, es va dissenyar la recerca que es presenta en aquest article. Els resultats de l'estudi semblen suggerir que les correccions no faciliten l'aprenentatge. Com presentem aquesta activitat de retroalimentació a l'alumnat i la posició que li donem dins d'un enfocament basat en el procés de l'escriptura seran clau per fer que les correccions siguin facilitadores de l'aprenentatge de la producció escrita.

La Genética forense y sus aplicaciones

La Genética forense es una disciplina que en la actualidad goza de una gran popularidad debido a su reiterada aparición en la prensa escrita, series de televisión y producciones cinematográfi cas. Aunque la palabra"forense" se asocia comúnmente con"médico forense" y el estudio de los cadáveres, técnicamente deriva de la palabra latina"forum", el foro, donde los romanos llevaban a cabo sus juicios. De forma que"forense" es un adjetivo que indica referencia a temas judiciales. Por tanto, la Genética forense no es más que la utilización de esta rama de la ciencia para resolver temas judiciales. Los ámbitos principales de actuación de la Genética forense son: la identificación de individuos para resolver diferentes tipos de delitos (asesinatos, robos, etc.), la identifi cación de individuos desaparecidos o de cuerpos seriamente dañados como consecuencia de una gran catástrofe (natural o producida por el hombre), los estudios de paternidad (o de otros grados de parentesco) y por último la identifi cación de diferentes especies o de individuos concretos de ciertas especies (para resolver temas de fraudes alimentarios, casos criminales, ataques terroristas mediante microorganismos, etc.).

Why Mathematics is essential in Biomedical Sciences degree?

Improvement of mathematical education and motivation of students in the mathematics" area is needed. What can be done? We introduce some ideas to generate the student"s interest for mathematics, because they often present difficulties in appreciating the relevance of mathematics and its role in the health sciences. We consider that a cornerstone in the strategy to attract the students" interest is linking the mathematics with real biomedical situations. We proceed in the following manner: We first present a real biomedical situation to produce interest and to generate curiosity. Second, we ask thought-provoking questions to students as: Which is the biomedical problem presented? Which is my knowledge on this situation? What could I do to solve this biomedical situation? Do I need some new mathematical concepts and procedures? Thereupon, the teacher explains the mathematical concepts necessary to solve the case presented, providing definitions, properties and tools for graphical display and/or mathematical calculations. In this learning methodology, ICTs were cornerstones for reaching the proposed competences. Furthermore, ICTs can also be used in the evaluative task in its two possible aspects: formative and for obtaining a qualification. Comments from students about this new mathematics teaching method indicate that the use of real biomedical case studies kept the lessons in mathematics interesting.

White eye phenotypes and their genetic analysis

An interesting case for undergraduate students of general Genetics is to consider that different genes can produce the same or similar phenotypes. We present here an experiment to discover that the same phenotype could be produced by different genes, and then, to carry out the genetic analysis of these genes. For this laboratory study we have used the following Drosophila melanogaster strains: white (white eyes) and scarlet-brown (white eyes).

Optimización de un nuevo método de preparación de óxidos mixtos tipo perovskita con vacantes de oxígeno.

Se han optimizado las condiciones para la deslitiación de compuestos de fórmula general La2/3-xLi3xTiO3 así como las de la posterior termólisis de compuestos de fórmula general La2/3-xTiO3-3x(OH)3x. En ambos procesos se mantiene la estructura perovskita cúbica Pm3m. Estudios preliminares de conductividad eléctrica indican que los compuestos La2/3-xTiO3-3x/2 obtenidos mediante química suave a partir de la perovskita de lantano y litio se comportan como semiconductores.

Highly textured Sr, Nb, co-doped BiFeO3 thin films grown on SrRuO3/Si substrates by rf-sputtering

In this study, (011)-highly oriented Sr, Nb co-doped BiFeO3 (BFO) thin films were successfully grown on SrRuO3/Si substrates by rf-magnetron sputtering. The presence of parasite magnetic phases was ruled out based on the high resolution x-ray diffraction data. BFO films exhibited a columnar-like grain growth with rms surface roughness values of 5.3 nm and average grain sizes of 65-70 nm for samples with different thicknesses. Remanent polarization values (2Pr) of 54 lC cm 2 at room temperature were found for the BFO films with a ferroelectric behavior characteristic of an asymmetric device structure. Analysis of the leakage mechanisms for this structure in negative bias suggests Schottky injection and a dominant Poole-Frenkel trap-limited conduction at room temperature. Oxygen vacancies and Fe3þ/Fe2þ trap centers are consistent with the surface chemical bonding states analysis from x-ray photoelectron spectroscopy data. The (011)-BFO/ SrRuO3/Si film structure exhibits a strong magnetic interaction at the interface between the multiferroic film and the substrate layer where an enhanced ferromagnetic response at 5 K was observed. Zero-field cooled (ZFC) and field cooled (FC) magnetization curves of this film system revealed a possible spin glass behavior at spin freezing temperatures below 30 K depending on the BFO film thickness.

Gene flow and gene flux shape evolutionary patterns of variation in Drosophila subobscura

Gene flow (defined as allele exchange between populations) and gene flux (defined as allele exchange during meiosis in heterokaryotypic females) are important factors decreasing genetic differentiation between populations and inversions. Many chromosomal inversions are under strong selection and their role in recombination reduction enhances the maintenance of their genetic distinctness. Here we analyze levels and patterns of nucleotide diversity, selection and demographic history, using 37 individuals of Drosophila subobscura from Mount Parnes (Greece) and Barcelona (Spain). Our sampling focused on two frequent O-chromosome arrangements that differ by two overlapping inversions (OST and O3+4), which are differentially adapted to the environment as observed by their opposing latitudinal clines in inversion frequencies. The six analyzed genes (Pif1A, Abi, Sqd, Yrt, Atpa and Fmr1) were selected for their location across the O-chromosome and their implication in thermal adaptation. Despite the extensive gene flux detected outside the inverted region, significant genetic differentiation between both arrangements was found inside it. However, high levels of gene flow were detected for all six genes when comparing the same arrangement among populations. These results suggest that the adaptive value of inversions is maintained, regardless of the lack of genetic differentiation within arrangements from different populations, and thus favors the Local Adaptation hypothesis over the Coadapted Genome hypothesis as the basis of the selection acting on inversions in these populations.

Inversion polymorphism in two Serbian natural populations of Drosophila subobscura: Analysis of long-term changes

To study whether inversions (or arrangements) by themselves or karyotypes are the main global warming adaptive target of natural selection, two Drosophila subobscura Serbian populations (Apatin and Petnica) were re analyzed using different statistical approaches. Both populations were sampled in an approximately 15 years period: Apatin in 1994 and 2008 + 2009 and Petnica in 1995 and 2010. For all chromosomes, the four collections studied were in Hardy-Weinberg equilibrium. Thus, it seems that inversions (or arrangements) combined at random to constitute populations" karyotypes. However, there were differences in karyotypic fre quencies along the years, although they were significant only for Apatin population. It is possible to conclude that inversions (or arrangements) are likely the target of natural selection, because they presented long term changes, but combine at random to generate the corresponding karyotypic combinations. As a consequence, the frequencies of karyotypes also change along time.

Drosophilid collection in the Font Groga site, Barcelona (Spain)

During October 23rd and 24th and November 2012 we collected a sample of drosophilids at Font Groga (Barcelona). This site is located on the foothills of the Tibidabo mountain, which is located on the northwest edge of Barcelona and at approximately 400m above sea level. The vegetation is typical for the area, and it is mainly composed of a sparse pine forest (Pinus pinea) with some oaks (Quercus ilex) and Mediterranean brushwood. Flies were netted over 12 baits containing fermenting bananas. A large proportion of D. simulans males was found. The invasive species D. suzukii (Calabria et al. 2010; Cini et al. 2012) was detected in a non-negligible quantity. Taking into account the number of males and females, the estimated Ne for D. suzukii in the Font Groga sample was 33.70. A similar value was obtained for D. subobscura (34.97). Finally, in the study of species diversity the values obtained for H" (Shannon diversity index) and J (Shannon uniformity index) were 0.678 and 0.421, respectively. These estimates are very similar to those obtained in September 2009 in Montpellier by Calabria (2012), who reported H" = 0.679 and J = 0.422, but differ from those reported by the same author in a Font Groga sample of October 2007 (H" = 0.904 and J = 0.505).

Behind and beyond of the cyborgs and robots ideas and realities: some techno-scientific and philosophical hints

We are progressively immersed in technology to such extend that in our everyday life we are and we do what technology allows us to be and to do. In this process, cyborgs and robots constitute elements that we analyze from a number of techno scientific and philosophical approaches. Additionally, we propose that a new concept: GEH (Genetic Engineered Human) as a new potential social imaginary element, which would be the human being improved by the broad-sense genetics engineer (that is, changing many genes by genetics engineer, modifications in the genome, cloning, and so on). If our aspirations as humans pass through technology and in particular for cyborgs, robots and GEH, the bidirectional links between these theoretical or real entities and our personal identities will be the more and more substantial in our society.
