User-centered requirement engineering for accessible chats in m-learning

Chat applications are useful synchronous tools in mobile learning (m-learning) environments. However, these tools have accessibility problems which cannot be avoided by students and teachers with disabilities. This paper focuses on detecting these accessibility problems. Specifically, this paper presents the Requirement Engineering (RE) process carried out to obtain the requirements needed to improve the interaction for people who experience problems with the Flow and Rhythm of the conversation in chats. A methodological approach has been followed and Software Engineering (SE) and Human Computer Interaction (HCI) disciplines were combined in order to improve the interaction during the chat.This research was partially supported by the MA2VICMR (S2009/TIC-1542) project.

Web Accessibility Requirements for Media Players

Video Content continues to strenghten on the Web, because of that fact, it is neccessary to include video content with suitable accessibility requirements to be used by all people. User Agent (such as player, browser), also have to include accessibility requirements. In this paper a set of basic guidelines is included for professionals who want to embed video players on their Web.This research work is supported by the Research Network MAVIR (S2009/TIC-1542 (see wwwmavir.net/)), and GEMMA (TSI-020302-2010-141) and SAGAS (TSI-020100-2010-184) research projects

Efectos de los incendios forestales sobre las propiedades del suelo en un pinar de repoblación (pinus pinaster), en Arenas de San Pedro

Se han estudiado dieciocho perfiles de suelos, en un pinar de repoblación de Pinus pinaster, en Arenas de San Pedro (Avila), desarrollados a partir del mismo material original (esquistos y cuarcitas). Trece de ellos sufrieron los efectos de un incendio forestal de superficie, que tuvo una duración de diez horas, realizando la toma de muestras a los diez meses del impacto, período durante el cual no hubo lluvias torrenciales. La evaluación del impacto sobre las propiedades físicas, químicas y mineralógicas, conduce a los siguientes resultados: oscurecimiento en superficie; destrucción de la estructura en los perfiles más afectados: no se observa modificación en la textura; aumento del pH, fundamentalmente en superficie, por el aporte de bases; incremento del carbono por combustión incompleta de la vegetación; aumento de la capacidad total de cambio en .

Study of alcohol consumption among students in Madrid and design of a health program

The aim is to know the prevalence and the rates of teenager’s alcohol consumption nowadays. We studied the alcohol consumption of 100 students male and female of Madrid Community. We performed a pilot descriptive study, using two surveys, one of them the Questionnaire AUDIT and the other one is a questionnaire designed by the Ministry of Health and Social Politics. There were the answered of 95% of the students. As results we found that the male students of 3rd and 4th years of Secundary Obligatory Education were the groups of teenagers who consume most alcohol. They medium age to started drinking was 13 years old. We also found out that 51 % of the students have consumed alcohol at least once in his life and the number of glasses that they drunk during different days of the week were 1-4 glasses. The percentage of teenagers, who consume on weekdays (15 %), is minor of whom they do it during the weekend (48 %). We can conclude that the teenagers began to drinks alcohol earlier than before and also they consumed frequently during the week. That’s why we have elaborated a health program. This program consists to work during three journeys with teenagers in order to inform them that the alcohol is a hard drug that can seriously injure their health

Accessibility evaluation of Moodle centred in visual impairements

Proceedings of: 7th International Conference on Web Information Systems and Technologies (WEBIST 2011), Noordwijkerhout, The Netherlands, May 6-9, 2011The use of new technologies has been increasing during last years in education. More specifically, the use of e-learning systems provides for students more freedom to learn through Internet when and where they prefer in each moment. However, e-learning tools are not perfect tools. Most of these e-learning tools present accessibility barriers, so not all students are able to use them completely in their studies. The goal of this paper is to evaluate if Moodle e-learning web tool is accessible for visually impaired people using assistive technologies like screen readers. The evaluation has been divided in two main objectives: first, to evaluate Moodle from a user perspective, simulating the interaction of a blind student with the system and using a screen reader; second, to evaluate Moodle from an accessibility expert perspective, analysing if Moodle is in accordance to ATAG and WCAG W3C guidelines.The work presented in this paper has been partially founded by GEMMA (TSI-020302-2010-141) and SAGAS (TSI-020100-2010-184) research projects

Securitization in Spain and the wealth effect for shareholders

This is an accepted manuscript of the article: López-Penabad, M., López-Andión, C., Iglesias-Casal, A., & Maside-Sanfiz, J. (2015). Securitization in Spain and the wealth effect for shareholders. International Review Of Economics & Finance, 37, 308-323. http://dx.doi.org/10.1016/j.iref.2014.12.003. © 2015. This manuscript version is made available under the CC-BY-NC-ND 4.0 license http://creativecommons.org/licenses/by-nc-nd/4.0/This paper examines the relationship between securitization, the issuing bank's overall exposure to risk and the response of the shareholder. Spanish securitization transactions are analyzed using event study methodology which reveals that securitization drains banks' wealth, was most pernicious immediately prior to the subprime crisis and affects small and medium-sized banks most with respect to mortgage collateral transactions. The indirect effect of securitization on originator risk does not affect share value, while the direct effect gives a positive relationship. This effect becomes non-significant in the years prior to the crisis and the shareholders no longer perceive this risk transferS

Accessibility barriers for users of screen readers in the Moodle learning content management system

In recent decades, the use of the Internet has spread rapidly into diverse social spheres including that of education. Currently, most educational centers make use of e-learning environments created through authoring tool applications like learning content management systems (LCMSs). However, most of these applications currently present accessibility barriers that make the creation of accessible e-learning environments difficult for teachers and administrators. In this paper, the accessibility of the Moodle authoring tool, one of the most frequently used LCMSs worldwide, is evaluated. More specifically, the evaluation is carried out from the perspective of two visually impaired users accessing content through screen readers, as well as a heuristic evaluation considering the World Wide Web Consortium's Authoring Tool Accessibility Guidelines. The evaluation results demonstrate that Moodle presents barriers for screen reader users, limiting their ability to access the tool. One example of accessibility problems for visually impaired users is the frequent inability to publish learning contents without assistance. In light of these results, the paper offers recommendations that can be followed to reduce or eliminate these accessibility barriers.This study has been partially funded by the MA2VICMR (S2009/TIC-1542) research project.Publicad

Influence of eating habits and alcohol consumption on the academic performance among a university population in the community of Madrid: A pilot study.

Objective To evaluate the association between dietary habits and alcohol consumption on academic performance among university students. Design Cross-sectional study. Setting University located in Madrid, Spain. Participants 56 university students of nursing (45 women and 11 men). The study complies with the Helsinki Declaration and was approved by the University Ethics Committee (36/2018). Main outcome measure Dietary intake and habits assessed with validated survey, alcohol consumption and academic performance. Analysis Chi-square test, Student's t-test, ANOVA analysis, Mann-Whitney test, Kruskal-Wallis analysis and Shapiro-Wilk test. Results The average daily energy intake of the students was 1918 ± 725 kcal and, on average, alcohol accounted for 6%. The increased energy contribution from alcohol was negatively correlated with body mass index (BMI). Moreover, an inverse association was also found in alcohol intake according to Body Mass Index (BMI) (p < 0.02). Students with failing grades (53.6%) reported a higher daily alcohol intake than those who passed (42.2 %) (32 g/day versus 24 g/day) (p = 0.043). Conclusions Alcohol consumption is related to both poor academic performance as well as diminished quality of life. Thus, it is of vital importance to undertake awareness campaigns at various levels to dissuade alcohol consumption especially at early ages.post-print440 K

Physical and Psychological Effects Related to Food Habits and Lifestyle Changes Derived from COVID-19 Home Confinement in the Spanish Population.

As a consequence of COVID-19, millions of households have suffered mobility restrictions and changes in their lifestyle over several months. The aim of this study is to evaluate the effects of COVID-19 home confinement on the food habits, lifestyle and emotional balance of the Spanish population. This cross-sectional study used data collected via an anonymous online questionnaire during the month before lockdown finished in Spain, with a total of 675 participants. 38.8% of the respondents experienced weight gain while 31.1% lost weight during confinement. The increase in body weight was positively correlated with age (Rs = 0.14, p < 0.05) and BMI (Rs = 0.20, p < 0.05). We also identified that 39.7% reported poorer quality sleep, positively correlated with BMI (Rs = −0.18, p < 0.05) and with age (Rs = −0.21, p < 0.05). 44.7% of the participants had not performed physical exercise during confinement with differences by sex (p < 0.05), by age (p < 0.05), by BMI (p < 0.05) and by sleep quality (p < 0.05). According to an emotional-eater questionnaire, 21.8% and 11% were classified as an emotional eater or a very emotional eater, respectively. We emphasize the importance of adopting a healthy lifestyle, as the COVID-19 pandemic is ongoing.post-print633 K
