Places making: participatory construction of scientifi c culture cities

In the framework of the European project Platform of Local Authorities and Communicators Engaged in Science (PLACES), we analyse the articulations between scientifi c communication, public perception of science, processes of citizen participation and apropiation of space, based on a case study of the inhabitants of Teruel city, Autonomous Community of Aragon, Spain. On the interrelationships between these issues, there are a number of contradictions, such as the difference between a high interest for information about science and technology and a low level of recognition and interaction with local institutions involved in those activities, the complex conceptualization of scientifi c space in relation to the “public-private” pair, or an articulation of a claiming civic rethoric and an insuffi cient co-responsibility. We conclude that, in a local context, the dimension of territoriality and, in particular, the identifi cation with the town, is a central mediation for activating citizen participation as part of processes of appropriation of space for setting up cities of scientifi c culture.

Monte Carlo simulation of properties of monolayers and metal islands adsorbed on metallic (111) surfaces

To obtain the surface stress changes due to the adsorption of metal monolayers onto metallic surfaces, a new model derived from thermodynamic considerations is presented. Such a model is based on continuum Monte Carlo simulations with embedded atom method potentials in the canonical ensemble, and it is extended to consider the behavior on different islands adsorbed onto (111) substrate surfaces. Homoepitaxial and heteroepitaxial systems are studied. Pseudomorphic growth is not observed for small metal islands with considerable positive misfit with the substrate. Instead, the islands become compressed upon increase of their size. A simple model is proposed to interpolate between the misfits of atoms in small islands and the pseudomorphic behavior of the monolayer.

Non-agrocultural co-peratives and economy transformation in Cuba: politic processes and strategies

Contribution of co-operatives has been demonstrated since the 1970s as the main development line in agricultural production in Cuba. In contrast, there has been a late recognition of urban co-operatives, even if the need of transformations based on the realization of property in different territorial scenarios had been identified. The article analyses the reform processes launched since the first decade of the 21st century focusing on the nature of the initiatives fostering formation and promotion of nonagricultural co-operatives including follow up of their performance. The potential and limitations of the recent experiences are examined in order to reflect on the organizational processes and transformations from the point of view of their members. To conclude, some questions are posed about whether these co-operatives are capable of avoiding the impact of earlier employment circumstances and of developing strategies aimed at reinforcing voluntary membership and autonomy on which they are founded.

Factores determinantes del uso de Internet en la comercialización del aceite de oliva. Análisis del sector en Cataluña

Las cooperativas son entidades con una gran presencia económica y social en España, y tienen una gran influencia en la economía rural de las zonas donde están ubicadas. El principal objetivo del presente trabajo es el análisis del uso de las nuevas tecnologías por parte de las cooperativas agroalimentarias, centrándose en las productoras de aceite de oliva para determinar los principales factores que condicionan su comportamiento en la Red. En el presente estudio se analizan sus sitios web y se determina qué tipo de información aporta, tanto datos generales como datos de comercialización. A partir de los resultados obtenidos, se busca la relación que pueda existir entre el tamaño de la cooperativa, su actividad exportadora o la actividad de comercio electrónico con la presencia online, mediante una regresión logística. De esta manera podremos conocer si realmente la implantación de nuevas tecnologías en las cooperativas permite desarrollar una óptima actividad económica.

2D-drop model applied to the calculation of step formation energies on a (111) substrate

A model is presented for obtaining the step formation energy for metallic islands on (1 1 1) surfaces from Monte Carlo simulations. This model is applied to homo (Cu/Cu(1 1 1), Ag/Ag(1 1 1)) and heteroepitaxy (Ag/Pt(1 1 1)) systems. The embedded atom method is used to represent the interaction between the particles of the system, but any other type of potential could be used as well. The formulation can also be employed to consider the case of other single crystal surfaces, since the higher barriers for atom motion on other surfaces are not a hindrance for the simulation scheme proposed.

Project evaluation SOU-estuTUtor: mentors’ perception

The introduction of new degrees in the Faculty of Education and the relevance of educational guidance comes to them, as a compulsory subject in all four grades started from 2009-2010, gives the opportunity to return and boost the University Guidance Service (UGS) as a means of consistency with the profile of their education and professional development of its students. The aim of the paper focuses on the evaluation of the results after the first year of implementing a peer mentoring project, SOU-estuTUtor Project, developed from UGS with all degree students of the Faculty of Education for Students new entrants. Program has been evaluated through the perception and satisfaction of the mentors on the organization, training, skills developed and adapted to the needs of students. After one academic year of implementation, the results show, on the one hand, the satisfaction and commitment of those involved and the partial response to the needs of the students served, as well as the optimization of the personal resources of the university but also some limitations that make it necessary to review the mentoring program in terms of control and duration of the process.

Predictors of attitudes toward inclusion of students with special educational needs in future education professionals

One of the main pillars in the development of inclusive schools is the initial teacher training. Before determining if it is necessary to make changes (and of what type) in training programs or curriculum guides related to the attention to diversity and inclusive education, the attitudes of future education professionals in this area should be analyzed. This includes the identification of the relevant predictors of inclusive attitudes. The research reported in this article pursued this objective, doing so with a quantitative survey methodology based on the use of cross-sectional structured data collection and statistical analyses related to the quality of the attitude questionnaire (factor analysis and Cronbach's alpha), descriptive statistics, correlations, hypothesis tests for difference of means, and regression analysis in order to predict attitudes towards inclusion in education. Firstly, the results show that the participants held very positive attitudes toward the inclusion of students with special educational needs. Particularly, older respondents, those with a longer training and, to a lesser extent, women and those who had been in touch with disabled people stood out within this attitude. Secondly, it is evidenced that self-transcendence values ​and, more weakly, contact, function as robust predictors of attitudes of future practitioners towards the inclusion of students with special needs. Some applications for the initial professionalization of educators are suggested in the discussion.

El Prácticum de Maestro en las voces de sus tutores. Balance del plan 2010 en la UAM

Se aborda un análisis del desarrollo del Prácticum de Maestro derivado del plan 2010, particularmente dirigido a valorar los cambios acaecidos en relación con el plan 2000, desde el punto de vista de sus tutores profesionales. La metodología es de tipo cualitativo, con entrevistas a 6 tutores profesionales innovadores de la red de centros de una universidad pública y a los 3 responsables de la materia analizada en ambos planes. Entre los resultados se observa que la percepción sobre las transformaciones operadas en el desarrollo en los centros de esta materia son poco apreciables, así como que la tutela del Prácticum se construye mediante una fuerte relación interpersonal de tutelado y tutor y que está vinculada al tipo de enseñanza que practica. Ello tiene consecuencias en la redefinición futura del Prácticum.

Conformal oxide coating of carbon nanotubes

The International Roadmap for Ferroelectric Memories requires three-dimensional integration of high-dielectric materials onto metal interconnects or bottom electrodes by 2010. Here, we demonstrate the possibility of conformally coating carbon nanotubes with high-dielectric oxide as a first step toward ultrahigh integration density of three-dimensional ferroelectric random access memories.

Liquid source misted chemical deposition process of three-dimensional nano-ferroelectrics with substrate heating

A modification of liquid source misted chemical deposition process (LSMCD) with heating mist and substrate has developed, and this enabled to control mist penetrability and fluidity on sidewalls of three-dimensional structures and ensure step coverage. A modified LSMCD process allowed a combinatorial approach of Pb(Zr,Ti)O-3 (PZT) thin films and carbon nanotubes (CNTs) toward ultrahigh integration density of ferroelectric random access memories (FeRAMs). The CNTs templates were survived during the crystallization process of deposited PZT film onto CNTs annealed at 650 degrees C in oxygen ambient due to a matter of minute process, so that the thermal budget is quite small. The modified LSMCD process opens up the possibility to realize the nanoscale capacitor structure of ferroelectric PZT film with CNTs electrodes toward ultrahigh integration density FeRAMs.

Rubén Darío's new unpublished and unknown documents: on La "Isla de Oro", the "Poema del Otoño" and the years of "Mundial"

This article studies and reproduces a group of documents that includes some hand-written and typed texts most likely authored by Rubén Darío, along with others where Darío’s authorship can be easily contested. These documents seem to have originated during the years of Mundial Magazine (1912-1914), and besides the interest for their probably unpublished nature, they also show the cooperation between Darío and his collaborators in the preparation of his original manuscripts right before being sent to the publishers.

Entre la "flânerie" y el ostracismo: la resignificación subjetiva de la ciudad en Fabián Casas y Martín Gambarotta

Desde los estudios pioneros de Walter Benjamín dedicados a la imagen del flâneur en la poesía de Baudelaire, la experiencia del sujeto poético y su íntima reconstrucción afectiva de la ciudad constituyen un índice significativo para aproximarnos a la experiencia de la vida moderna. En este artículo, nos interesa revisar cuáles son las particularidades que distinguen esta experiencia en un corpus de poesía argentina reciente -los libros Punctum y Refrito, de Martín Gambarotta, y Horla City y otros, de Fabián Casas-, que durante las décadas de 1990 y 2000 tematiza, con insistencia y mediante opciones diversas, la relación sujeto-ciudad. En dichos textos, es posible releer una continuidad -relativamente canónicadel paseante por los márgenes periféricos de la modernidad -en el caso de Casas- y la reclusión voluntaria, como repliegue extremo ante la vivencia del deambular callejero, que se percibe como intimidante en Gambarotta.

La narrativa indigenista en Argentina. Una doble denuncia

Desde tiempos de José Carlos Mariátegui, la crítica literaria indigenista viene articulando un discurso etnocentrista cuyo eje de producción se sitúa en Perú y los países vecinos, pero rara vez se ha mencionado una obra argentina que trate sobre las desigualdades que sufren los indígenas de ese país. Ni siquiera la academia argentina ha analizado ninguna novela desde la óptica indigenista.En un país cuyos gobiernos, desde el siglo XIX, han tratado de borrar cualquier traza de sangre indígena en su población, ya sea mediante la asimilación, exterminio o invisibilidad, y cuyas zonas de mayor asentamiento indígena se encuentran lejos del hegemónico Buenos Aires, las narraciones de problemas sociales ajenos quedaban encajonadas en el recóndito mundo de la literatura regional.Sin embargo, durante los años de eclosión del movimiento indigenista, escritores argentinos se hicieron eco de los sufrimientos y demandas de sus compatriotas indígenas por medio de novelas que sobrepasaron el peyorativo epíteto regionalista y que incomprensiblemente, han sido olvidadas.En este artículo, que forma parte de un estudio más amplio, se aborda el silencio crítico, se contextualiza la producción indigenista de la época y se analizan brevemente algunas de las obras.

Simulation study of Pd submonolayer films on Au(hkl) and Pt(hkl) and their relationship to underpotential deposition

The structure and stability of palladium adlayers on Au(hkl) and Pt(hkl) were studied at different coverage degrees by means of Monte Carlo simulations using the interatomic potentials of the embedded atom model. In all cases the Pd films were found to grow epitaxially and pseudomorphically with the crystallographic orientation of the substrate. The differences and similarities of the adlayer with the substrate were analyzed.
