Knowledge-action integration through the media in indigenous communities in Ecuador

The binomial knowledge/action understood under the biunivocal relationship of both components is the basis of planning from a postmodern approach. Within this binomial, social communication gives appropriate information, nurtures the knowledge that leads to transformative action, promotes participation and enhances the community?s self-esteem and recognition; to deeply reflect on action is a source of new knowledge; and communication fosters the adoption of the new knowledge by the community with new actions that feed the process knowledge/action as a planning source. From this approach the project Radio Message is born as a new communication channel with the aim of offering Andean indigenous communities from the area of Cayambe (Ecuador), a series of multidisciplinary training programs that enable transformative action with a strong effect on the life quality in these communities and their importance as social actors. The contents are designed through participatory communication between the training authorities and the communities themselves, analyzing their opportunities and needs. In this research the impact of social media in the development of more than 100 indigenous communities in Cayambe is analyzed.

Use and abuse of audivisual media in the college classroom. Slides show and web pages

The multimedia development that has taken place within the university classrooms in recent years has caused a revolution at psychological level within the collectivity of students and teachers inside and outside the classrooms. The slide show applications have become a key supporting element for university professors, who, in many cases, rely blindly in the use of them for teaching. Additionally, ill-conceived slides, poorly structured and with a vast amount of multimedia content, can be the basis of a faulty communication between teacher and student, which is overwhelmed by the appearance and presentation, neglecting their content. The same applies to web pages. This paper focuses on the study and analysis of the impact caused in the process of teaching and learning by the slide show presentations and web pages, and its positive and negative influence on the student’s learning process, paying particular attention to the consequences on the level of attention within the classroom, and on the study outside the classroom. The study is performed by means of a qualitative analysis of student surveys conducted during the last 8 school Civil Engineering School at the Polytechnic University of Madrid. It presents some of the weaknesses of multimedia material, including the difficulties for students to study them, because of the many distractions they face and the need for incentives web pages offer, or the insignificant content and shallowness of the studies due to wrongly formulated presentations.

Feasibility assessment of the interactive use of a Monte Carlo algorithm in treatment planning for intraoperative electron radiation therapy

This work analysed the feasibility of using a fast, customized Monte Carlo (MC) method to perform accurate computation of dose distributions during pre- and intraplanning of intraoperative electron radiation therapy (IOERT) procedures. The MC method that was implemented, which has been integrated into a specific innovative simulation and planning tool, is able to simulate the fate of thousands of particles per second, and it was the aim of this work to determine the level of interactivity that could be achieved. The planning workflow enabled calibration of the imaging and treatment equipment, as well as manipulation of the surgical frame and insertion of the protection shields around the organs at risk and other beam modifiers. In this way, the multidisciplinary team involved in IOERT has all the tools necessary to perform complex MC dosage simulations adapted to their equipment in an efficient and transparent way. To assess the accuracy and reliability of this MC technique, dose distributions for a monoenergetic source were compared with those obtained using a general-purpose software package used widely in medical physics applications. Once accuracy of the underlying simulator was confirmed, a clinical accelerator was modelled and experimental measurements in water were conducted. A comparison was made with the output from the simulator to identify the conditions under which accurate dose estimations could be obtained in less than 3 min, which is the threshold imposed to allow for interactive use of the tool in treatment planning. Finally, a clinically relevant scenario, namely early-stage breast cancer treatment, was simulated with pre- and intraoperative volumes to verify that it was feasible to use the MC tool intraoperatively and to adjust dose delivery based on the simulation output, without compromising accuracy. The workflow provided a satisfactory model of the treatment head and the imaging system, enabling proper configuration of the treatment planning system and providing good accuracy in the dosage simulation.

A comparison of open-source segmentation architectures for dealing with imperfect data from the media in speech synthesis

Traditional Text-To-Speech (TTS) systems have been developed using especially-designed non-expressive scripted recordings. In order to develop a new generation of expressive TTS systems in the Simple4All project, real recordings from the media should be used for training new voices with a whole new range of speaking styles. However, for processing this more spontaneous material, the new systems must be able to deal with imperfect data (multi-speaker recordings, background and foreground music and noise), filtering out low-quality audio segments and creating mono-speaker clusters. In this paper we compare several architectures for combining speaker diarization and music and noise detection which improve the precision and overall quality of the segmentation.

Youth participation in development planning: case study of Sayausí (Rural Parish) Cuenca-Ecuador

Young people now represent the highest percentage of the world population. Soon, they will be seniors and they will take decisions for a more orderly and equitable world. For this reason, the participation of young people in development planning is very important and many countries are trying to promote it through various measures. This article analyzes the trajectory of youth participation in the Latin American region and specifically the profile of youth participation in Ecuador, country in which the Constitution recognizes the strategic role of youth in development. The case study of Sayausí rural parish in canton Cuenca is analyzed, through surveys, interviews and an Empowerment Evaluation workshop to young people and decentralized government. The results obtained allow to propose strategies to help improve the participation of youth in the community.
