Las dificultades para la educación integradora desde la perspectiva de futuros maestros de inglés
2009
This article presents and analyses the findings of a qualitative study about the perceptions expressed by prospective primary teachers of English about integration and response to special educational needs in the mainstream. The analysis of the data, obtained in the course of the practice teaching period of their course, evidences their ideas on integrative education; besides, a frequent lack of experiences of genuine integrative practices in such a critical period of professional preparation is identified. El presente artículo presenta y analiza los hallazgos de un estudio de naturaleza cualitativa sobre las percepciones que expresan futuros maestros especialistas de inglés en el transcurs…
Attitudes of elementary school teachers towards inclusive education in Ecuador
2020
Resumen Las actitudes de los docentes hacia la inclusión son un factor relevante para permitir que las políticas educativas inclusivas puedan materializarse verdaderamente en prácticas inclusivas. Estas actitudes se ven influenciadas por diferentes variables, entre las que se encuentran la formación y experiencia en el ámbito de la inclusión y las condiciones y recursos disponibles para llevar a cabo prácticas educativas. El objetivo del presente trabajo es analizar las actitudes hacia la inclusión educativa en una muestra de 66 docentes de 15 centros educativos de la ciudad de Cuenca (Ecuador), mediante una escala tipo Likert de 23 ítems. Los resultados muestran que los docentes presentan …
Extended X-ray emission in PKS 1718-649
2018
PKS 1718$-$649 is one of the closest and most comprehensively studied candidates of a young active galactic nucleus (AGN) that is still embedded in its optical host galaxy. The compact radio structure, with a maximal extent of a few parsecs, makes it a member of the group of compact symmetric objects (CSO). Its environment imposes a turnover of the radio synchrotron spectrum towards lower frequencies, also classifying PKS 1718$-$649 as gigahertz-peaked radio spectrum (GPS) source. Its close proximity has allowed the first detection of extended X-ray emission in a GPS/CSO source with Chandra that is for the most part unrelated to nuclear feedback. However, not much is known about the nature …
The history of chemical enrichment in the intracluster medium from cosmological simulations
2017
The distribution of metals in the intracluster medium (ICM) of galaxy clusters provides valuable information on their formation and evolution, on the connection with the cosmic star formation and on the effects of different gas processes. By analyzing a sample of simulated galaxy clusters, we study the chemical enrichment of the ICM, its evolution, and its relation with the physical processes included in the simulation and with the thermal properties of the core. These simulations, consisting of re-simulations of 29 Lagrangian regions performed with an upgraded version of the SPH GADGET-3 code, have been run including two different sets of baryonic physics: one accounts for radiative coolin…
Solubility and acid-base properties and activity coefficients of chitosan in different ionic media and at different ionic strengths, at T=25°C
2009
Studies on the acid-base properties and solubility of a polyammonium polyelectrolyte (chitosan) with different molecular weights (MW 310 and 50 kDa), were performed at T=25 °C, in the pH range 2.5–7. The protonation of chitosan was investigated by potentiometry ([H+]-glass electrode) in NaCl, NaNO3 and mixed NaNO3+Na2SO4 ionic media, at different ionic strengths. Protonation constants were calculated as a function of dissociation degree α by means of two different models, namely, a simple linear model and the modified Henderson–Hasselbalch equation. Experimental data were also fitted using a model independent of α (Diprotic-like model), according to which the acid-base properties can be sim…
