This article explores the experiences and particularities faced by partial/full time-lecturers in a precarious situation who opt, without apparent success, for a full time job within the professional system of higher education. Following a narrative methodology, it explores the way in which teachers (eight women and six men, all of them university partial or full time lecturers in different areas) construct and legitimize certain conceptions about the professional sphere in the university that have obvious repercussions on their personal and professional identities. The results, organized around a narrative that takes whose reference is the daily life of a teacher in precarious conditions, reflect the stress to which teachers are subjected as part of the relentless programs of university evaluation and accreditation, the distancing of good teaching in favour of demonstrable quality as an investigator and the possibility of suffering from teacher burnout syndrome no sooner than having commenced a professional career.

The purpose of this study is to reveal the perceptions of the teachers, administrators, and academics who had to continue distance education during COVID-19 epidemic disease period, about the problems they experienced and the strategies to cope with the challenges. The working group of the current study consists of 65 teachers. The data were collected via an open-endedwritten interview. Content analysis was applied for analysis of the data gathered. Various important results regarding the use of distance education were obtained during the pandemic period and yielded significant findings. The first and the most important finding is that theachers have difficulties in internet access and lack of infrastructure, classroom management and human resources. Another challenge that participants reported was about teachers’ and students’ behaviours. The last theme stated by the participants is the distance education process itself. The findings reveal that the participants determined their strategies to deal with these problems with new arrangements regarding the classroom management, getting help from colleagues, family members and experts and communicating with students and parents. It can be certainly suggested that the participants are not ready for the distance education process and there is a lack of application in this regard; such as technology support and distance education training, and moreover, the participants do not have sufficient knowledge and experience about distance education.

This paper forms part of the results of the ongoing doctoral thesis with the title Resilience and intellectual disability in residential environments using life stories. From a narrative and inclusive biographical approach, we delve deeper into the life history of four people who have been diagnosed with intellectual disability and who live in a residential environment in the city of Malaga (Spain). The field work was carried out using semi-structured and in-depth biographical interviews. The analysis reveals one of the conceptions that is a priority in this paper: the “social image” of disability, structured in three main areas for the purposes of this article: “the image of disability from social culture and identity”, “the image of disability from close contexts” and, lastly, “subversive experiences to the image of disability from inside”. In conclusion, there is a commitment to continue generating another social image of disability based on a more social and inclusive paradigm.

This paper presents a new application for analyzing electroencephalogram (EEG) signals. The signals are pre-filtered through MATLAB's EEGLAB tool. The created application performs a convolution between the original EEG signal and a complex Morlet wavelet. As a final result, the application shows the signal power value and a spectrogram of the convoluted signal. Moreover, the created application compares different EEG channels at the same time, in a fast and straightforward way, through a time and frequency analysis. Finally, the effectiveness of the created application was demonstrated by performing an analysis of the alpha signals of healthy subjects, one signal created by the subject with eyes closed and the other, with which it was compared, was created by the same subject with eyes open. This also served to demonstrate that the power of the alpha band of the closed-eyed signal is higher than the power of the open-eyed signal.

Es sabido que el reconocimiento de objetos en imágenes está a la orden del día. No es raro observar que Facebook recomienda a sus usuarios etiquetar personas en fotografías, por mencionar algún ejemplo. En varios países, especialmente Estados Unidos y miembros de la Unión Europea, ya se cuenta con herramientas para detectar billetes y sus denominaciones a través de aplicaciones móvil. En esta investigación se busca el desarrollo de una herramienta capaz de reconocer y clasificar los billetes mexicanos actualmente en circulación, a través de una aplicación móvil capaz de tomar fotografías o seleccionar imágenes existentes para la detección, usando una red neuronal entrenada para lograr nuestro objetivo: una detección y clasificación de billetes que sea eficiente en al menos el 90% de los casos.

El objetivo de la investigación es evaluar el aporte socio-económico de las cooperativas de Ahorro y Crédito en el cantón Chillanes provincia de Bolívar, para lo cual se aplicaron encuestas a una muestra de 198 habitantes, también se realizó una evaluación a las dos cooperativas del sector: San José Ltda. y Juan Pio de Mora y se determinó que la primera es la más representativa por su nivel de captaciones y colocaciones enfocando el estudio en esta; a través del análisis de sus indicadores de desempeño durante los años 2015, 2016 y 2017, de los cuales se comprobó que es una institución muy sólida y que goza de la confianza de sus asociados. El resultado obtenido fue que el 70% de créditos otorgados son destinados al sector agrícola, lo cual evidencia el desarrollo de la inclusión financiera.

Encouraging the adoption of a culture of quality in tourist accommodation companies has become a primary objective for the Ministry of Tourism, due to the accelerated growth of tourism and the great global competition, for this reason it is essential that companies that provide services understand the importance of acquiring knowledge, skills and abilities that allow the staff to offer quality in the attention they provide, consequently the present research topic provides a consolidation of information referring to quality principles focused on customer service applied to the accommodation facilities of the Pujilí canton, this project was developed through the initial system of organizational management (SIGO-Ecuador) that is currently used to diagnose quality in tourist establishments, in this same sense an international tool known as HotelQual was used To measure the perception of the guests, in this way the final result showed that the quality of the accommodation service directly influences the perceptions of the same, so it is necessary to improve the quality in the accommodation establishments so that in this way the clients' perceptions are positive and their total satisfaction is achieved.
