Aportaciones para la investigación : dirección de lectura en las imágenes fijas proyectadas.

Investigar si existe una dirección de lectura en las diapositivas. 62 alumnos de quinto, sexto, séptimo y octavo de EGB. Exposición de diapositivas. Estadística porcentual. No existe una dirección común de lectura en las diapositivas. Pero la iniciación de dicha lectura es por la parte superior izquierda. En muchos países se considera normal la preponderancia del ojo derecho sobre el izquierdo porque la lectura se hace de izquierda a derecha, sin embargo, la mitad o más de la población mundial lee de derecha a izquierda o de arriba abajo. En el caso de un zurdo ocular, para él la parte de la pantalla o diapositiva situada a la izquierda del eje medio será mejor explorada, mejor aprendida y mejor percibida que la parte derecha, suponiendo, evidentemente, que todos los demás factores sean iguales, es decir que la densidad de información de la parte izquierda de la imagen sea idéntica a la de la parte derecha y que los valores afectivos de los dos sectores de la pantalla o la diapositiva se equilibren. Es evidente, que cuanto más a la izquierda de la diapositiva esté situado un zurdo ocular menores serán sus posibilidades de tener una percepción correcta de la totalidad de la misma, puesto que la visión de la parte derecha de la diapositiva más alejada de sus ojos que la parte izquierda, estará peor explorada.

Forward modelling to determine the observational signatures of white-light imaging and interplanetary scintillation for the propagation of an interplanetary shock in the ecliptic plane

Recent coordinated observations of interplanetary scintillation (IPS) from the EISCAT, MERLIN, and STELab, and stereoscopic white-light imaging from the two heliospheric imagers (HIs) onboard the twin STEREO spacecraft are significant to continuously track the propagation and evolution of solar eruptions throughout interplanetary space. In order to obtain a better understanding of the observational signatures in these two remote-sensing techniques, the magnetohydrodynamics of the macro-scale interplanetary disturbance and the radio-wave scattering of the micro-scale electron-density fluctuation are coupled and investigated using a newly constructed multi-scale numerical model. This model is then applied to a case of an interplanetary shock propagation within the ecliptic plane. The shock could be nearly invisible to an HI, once entering the Thomson-scattering sphere of the HI. The asymmetry in the optical images between the western and eastern HIs suggests the shock propagation off the Sun–Earth line. Meanwhile, an IPS signal, strongly dependent on the local electron density, is insensitive to the density cavity far downstream of the shock front. When this cavity (or the shock nose) is cut through by an IPS ray-path, a single speed component at the flank (or the nose) of the shock can be recorded; when an IPS ray-path penetrates the sheath between the shock nose and this cavity, two speed components at the sheath and flank can be detected. Moreover, once a shock front touches an IPS ray-path, the derived position and speed at the irregularity source of this IPS signal, together with an assumption of a radial and constant propagation of the shock, can be used to estimate the later appearance of the shock front in the elongation of the HI field of view. The results of synthetic measurements from forward modelling are helpful in inferring the in-situ properties of coronal mass ejection from real observational data via an inverse approach.

Codification vs personalisation: A study of the information evaluation practice between aerospace and construction industries

In the emerging digital economy, the management of information in aerospace and construction organisations is facing a particular challenge due to the ever-increasing volume of information and the extensive use of information and communication technologies (ICTs). This paper addresses the problems of information overload and the value of information in both industries by providing some cross-disciplinary insights. In particular it identifies major issues and challenges in the current information evaluation practice in these two industries. Interviews were conducted to get a spectrum of industrial perspectives (director/strategic, project management and ICT/document management) on these issues in particular to information storage and retrieval strategies and the contrasting approaches to knowledge and information management of personalisation and codification. Industry feedback was collected by a follow-up workshop to strengthen the findings of the research. An information-handling agenda is outlined for the development of a future Information Evaluation Methodology (IEM) which could facilitate the practice of the codification of high-value information in order to support through-life knowledge and information management (K&IM) practice.
