Stars and planets.

Bajo la forma de preguntas y respuestas trata de despertar la curiosidad por la astronomía haciendo hincapié en las características e interrelaciones de las estrellas y planetas en nuestra galaxia. Exploran diversos aspectos de la astronomía, incluyendo el sistema solar, estrellas, planetas, lunas, asteroides y cometas. Recomendado para niños de ocho a doce años.

Stars and constellations.

Describe los orígenes y la composición de las estrellas y las constelaciones contestando a preguntas como si hay constelaciones de ochenta y ocho estrellas, si nuestro sol brillará otros cinco billones de años o si las estrellas gigantes se convertirán, cuando mueran, en agujeros negros. Tiene glosario, bibliografía y direcciones de internet.

Deck of stars.

Cincuenta y dos cartas que ponen de manifiesto todo sobre el estudio de las estrellas. Paso a paso enseña cómo elegir estrellas mirando los equipos, identificar las constelaciones, y grabar lo visto usando astrofotografía.

Some of my favourite film stars : una experiencia de aula utilizando Internet.

Se describe la experiencia llevada a cabo con alumnos de primero de ESO en la asignatura de Inglés y que consistía en la búsqueda de un personaje de su interés en la página web: www.biography.com y en analizar su biografía a través de diversas actividades utilizando el idioma inglés. Los objetivos del trabajo son: desarrollar la capacidad lectora de los alumnos en inglés aún cuado no entiendan todo, leer para obtener la información específica, aprender a intuir el significado de palabras desconocidas por el contexto, practicar el vocabulario y las estructuras estudiadas, conseguir que los alumnos adquieran confianza a la hora de enfrentarse a páginas web en inglés y capacitar a los alumnos para que realicen búsquedas en Internet de material en inglés.

When the rising dragon sees fading stars: China's view of the European Union. CEPS Special Report No. 73, 29 November 2012

This CEPS Special Report gives an overview of China’s perceptions of the EU and the protection of Chinese investments in Europe since the outbreak of the European sovereign debt crisis, especially since the more concrete talks in late 2011 on possible financial support from China. Although the top leadership of the communist party of China (CPC) changed in its recent handover, the perceptions described in this paper are likely to remain the same, just as the main tenets of China’s foreign policy are unlikely to change in the near future. The report argues that while the EU’s image has suffered greatly from the sovereign debt crisis and the way it has been handled, there is room to improve China’s view of Europe and for the EU to maintain a relatively strong negotiation position towards China.

Stars in their eyes: what eye-tracking reveal about multimedia perceptual quality

Perceptual multimedia quality is of paramount importance to the continued take-up and proliferation of multimedia applications: users will not use and pay for applications if they are perceived to be of low quality. Whilst traditionally distributed multimedia quality has been characterised by Quality of Service (QoS) parameters, these neglect the user perspective of the issue of quality. In order to redress this shortcoming, we characterise the user multimedia perspective using the Quality of Perception (QoP) metric, which encompasses not only a user’s satisfaction with the quality of a multimedia presentation, but also his/her ability to analyse, synthesise and assimilate informational content of multimedia. In recognition of the fact that monitoring eye movements offers insights into visual perception, as well as the associated attention mechanisms and cognitive processes, this paper reports on the results of a study investigating the impact of differing multimedia presentation frame rates on user QoP and eye path data. Our results show that provision of higher frame rates, usually assumed to provide better multimedia presentation quality, do not significantly impact upon the median coordinate value of eye path data. Moreover, higher frame rates do not significantly increase level of participant information assimilation, although they do significantly improve overall user enjoyment and quality perception of the multimedia content being shown.

Towards the main sequence: detailed analysis of weak line and post-T Tauri stars

A detailed study was performed for a sample of low-mass pre-main-sequence (PMS) stars, previously identified as weak-line T Tauri stars, which are compared to members of the Tucanae and Horologium Associations. Aiming to verify if there is any pattern of abundances when comparing the young stars at different phases, we selected objects in the range from 1 to 100 Myr, which covers most of PMS evolution. High-resolution optical spectra were acquired at European Southern Observatory and Observatorio do Pico dos Dias. The stellar fundamental parameters effective temperature and gravity were calculated by excitation and ionization equilibria of iron absorption lines. Chemical abundances were obtained via equivalent width calculations and spectral synthesis for 44 per cent of the sample, which shows metallicities within 0.5 dex solar. A classification was developed based on equivalent width of Li I 6708 angstrom and Ha lines and spectral types of the studied stars. This classification allowed a separation of the sample into categories that correspond to different evolutive stages in the PMS. The position of these stars in the Hertzsprung-Russell diagram was also inspected in order to estimate their ages and masses. Among the studied objects, it was verified that our sample actually contains seven weak-line T Tauri stars, three are Classical T Tauri, 12 are Fe/Ge PMS stars and 21 are post-T Tauri or young main-sequence stars. An estimation of circumstellar luminosity was obtained using a disc model to reproduce the observed spectral energy distribution. Most of the stars show low levels of circumstellar emission, corresponding to less than 30 per cent of the total emission.
