Improving the Quality of Teaching Internships with the Help of the Platforms

This article presents an empirical study on the perceptions of university students toward the development of the teaching practicum, using the CourseSites platform as a communication and support tool for their training. The opinions of the students were collected through a questionnaire. The sample consisted of 1500 students who were registered in the degrees of Early Childhood Education, Primary Education and Pedagogy (2008-2018). A descriptive, inferential and multi-level analysis was conducted, which confirmed that future teachers had activated their professional competences, as they had the chance to share their internship experiences with their faculty members and with their own classmates

Production of ordered silicon nanocrystals by low-energy ion sputtering

We report on the production of ordered assemblies of silicon nanostructures by means of irradiation of a Si(100) substrate with 1.2 keV Ar ions at normal incidence. Atomic Force and High-Resolution Transmission Electron microscopies show that the silicon structures are crystalline, display homogeneous height, and spontaneously arrange into short-range hexagonal ordering. Under prolonged irradiation (up to 16 hours) all dot characteristics remain largely unchanged and a small corrugation develops at long wavelengths. We interpret the formation of the dots as a result of an instability due to the sputtering yield dependence on the local surface curvatureComment: 4 two-column pages (revtex4), 3 figures (higher quality copies in the printed jrnl. version

Values of the Parents of Pupils with Special Educational Needs due to Sociocultural Background

The aim of the study was to investigate the values behind the nature and behaviour of parents with children who have Special Educational Needs, and the way they approach their children´s schooling. The views of two hundred and sixty-eight parents living in a socially and culturally disadvantaged area, were evaluated using the Hall-Tonna Inventory of Values. The results showed that there are differences in the parents’ hierarchy of values according to whether the school they have chosen for their children is inside or outside the area. The principle differences are in the content of some of the priority values selected by each group, and/or in the priority that each group gives to some of the values common to both groups. The implications of how the parents prioritise the values are discussed with regard to their own personal development and the education of their children

Alternative Lines of Action for the Design of Online Multimedia Material Directed towards the Collaborative Training of Teachers in the Design of the Teaching

The aim of the study was to evaluate the potential for online multimedia materials as alternative learning tools for the collaborative training of teachers in the design of research-based teaching. A case study using a team of three trainee teachers was used to develop a process of initial training in the design of a constructivist and research-based teaching unit supported by online multimedia material. The results obtained from the research allowed some principles to be identified, and basic recommendations and alternative lines of action to be given for designing online multimedia materials. Online multimedia materials can be alternative teaching tools that contribute (with other materials) to the development of constructivist, collaborative and research-based strategies which help provide the necessary support for improving the initial and ongoing training of new teachers in the design of teaching from a research perspectiv

Identification of intergenomic translocations involving wheat, Hordeum vulgare and Hordeum chilense chromosomes by FISH

4 pages: 1 figure: 1 tableIntergenomic translocations between wheat, Hordeum chilense and Hordeum vulgare have been obtained in tritordeum background. Advanced lines from the crosses between three disomic chromosome addition lines for chromosome 2Hv, 3Hv, and 4Hv of barley (Hordeum vulgare) in Triticum aestivum cv. Chinese Spring (CS) and hexaploid tritordeum (2n=6x=42, AABBHchHch) were analyzed. Multicolour FISH using both genomic DNA from H. chilense and H. vulgare were used to establish the presence and numbers of H. vulgare introgressions into tritordeum. Interspecific H. vulgare-H. chilense and intergeneric wheat-H. vulgare and wheat-H. chilense translocations were identified. Frequencies of plants containing different kinds of intergenomic translocations between chromosome arms are presented. These lines can be useful for introgressing into tritordeum characters of interest from H. vulgare.CICYT, Spain, projects AGF98- 0945-CO2-01 and AGF99-1036-C02-02Peer reviewe

Costos de engorde del ganado bovino en las fincas Los Angeles, Villa Nueva y Quinta Dora en el Departamento de Matagalpa en el primer semestre del año 2008

En los Costos de Engorde del Ganado Bovino, es relevante conocer el funcionamiento y operatividad de esta actividad para trabajar los recursos de una manera eficaz y eficiente por lo que se debe hacer énfasis en el manejo zootécnico el cual está compuesto por factores como suplementos alimenticios necesarios para la nutrición y engorde de los animales, la sanidad animal para controlar y prevenir la enfermedades a las que están expuestos los novillos y determinar las razas que cumplan las características propias de animales para engorde. Se deben clasificar los costos de acuerdo a la variabilidad, para poder obtener información real y concreta de la finca, ya sea para mano de obra tanto temporal como permanente, así como los materiales y suministros que consume el novillo, y otros gastos indirectos lo cual permitirá que al finalizar este proceso de engorde se analice sí los costos se mantuvieron estables o aumentaron en relación a años anteriores y de esta manera conocer la rentabilidad de la actividad ganadera. La mayoría de los ganaderos emplean una contabilidad sencilla, sin embargo existen fincas agropecuarias que trabajan con un sistema de contabilidad formal y tienen sistemas contables que registran la información con mayor rapidez, además de llevar todos los documentos y registros que soportan cada transacción, y permiten un mejor control de la finca. Quinta Dora registra las operaciones de forma sencilla, empleando para el engorde de su ganado un sistema mixto y es dirigida personalmente por su propietario; Finca Villa Nueva ocupa un sistema extensivo para el engorde de sus animales, llevando el registro de sus ingresos y egresos únicamente y es dirigida por su propietario, a diferencia de finca los Ángeles quienes trabajan con sistema contable por partida doble, posee un organigrama jerárquico que orienta la comunicación entre los trabajadores y utilizan el sistema extensiv

On competitive bidding: scoring and position probability graphs

Iso-score curves graph (iSCG) and mathematical relationships between Scoring Parameters (SP) and Forecasting Parameters (FP) can be used in Economic Scoring Formulas (ESF) used in tendering to distribute the score among bidders in the economic part of a proposal. Each contracting authority must set an ESF when publishing tender specifications and the strategy of each bidder will differ depending on the ESF selected and the weight of the overall proposal scoring. The various mathematical relationships and density distributions that describe the main SPs and FPs, and the representation of tendering data by means of iSCGs, enable the generation of two new types of graphs that can be very useful for bidders who want to be more competitive: the scoring and position probability graphs

El principio de igualdad de oportunidades en la formación

El proyecto Andalucía en e-Igualdad en su Eje 2. Asistencia a favor de las personas, en coherencia con el objetivo de Equal, trata de combatir la discriminación y la desigualdad en el mercado laboral, y así se realizaron una serie de actividades innovadoras, encaminadas al desarrollo de competencias específicas para la formación de la mujer.
