Modelling Dependency Structures Produced by the Introduction of a Flipped Classroom

Teaching processes have been changing in the lasts few decades from a traditional lecture-example-homework format to more active strategies to engage the students in the learning process. One of the most popular methodologies is the flipped classroom, where traditional structure of the course is turned over by moving out of the classroom, most basic knowledge acquisition. However, due to the workload involved in this kind of methodology, an objective analysis of the results should be carried out to assess whether the lecturer’s workload is worth the effort or not. In this paper, we compare the results obtained from two different methodologies: traditional lecturing and flipped classroom methodology, in terms of some performance indicators and an attitudinal survey, in an introductory statistics course for engineering students. Finally, we analysed the changes in the relationships among variables of interest when the traditional teaching was moved to a flipped classroom by using Bayesian networks

A Microcontroller Based System for Controlling Patient Respiratory Guidelines

The need of making improvements in obtaining (in a non-invasive way) and monitoring the breathing rate parameters in a patient emerges due to (1) the great amount of breathing problems our society suffer, (2) the problems that can be solved, and (3) the methods used so far. Non-specific machines are usually used to carry out these measures or simply calculate the number of inhalations and exhalations within a particular timeframe. These methods lack of effectiveness and precision thus, influencing the capacity of getting a good diagnosis. This proposal focuses on drawing up a technology composed of a mechanism and a user application which allows doctors to obtain the breathing rate parameters in a comfortable and concise way. In addition, such parameters are stored in a database for potential consultation as well as for the medical history of the patients. For this, the current approach takes into account the needs, the capacities, the expectations and the user motivations which have been compiled by means of open interviews, forum discussions, surveys and application uses. In addition, an empirical evaluation has been conducted with a set of volunteers. Results indicate that the proposed technology may reduce cost and improve the reliability of the diagnosis.Ministerio de Economía y Competitividad TIN2016-76956-C3-2-RMinisterio de Economía y Competitividad TIN2015-71938-RED

Desnutrición en Bolivia: la geografía y la cultura sí importan

(Disponible en idioma inglés únicamente) La frecuencia de problemas de salud y de desnutrición en Bolivia es alarmantemente elevada, incluso comparada con la de otros países en desarrollo. En este estudio se analiza el vínculo entre una medida bidimensional de la salud infantil, compuesta por los puntajes z de estatura y peso, y un conjunto de factores determinantes de la nutrición infantil relacionados con los contextos físico y cultural, las características de la madre, los activos del hogar y el acceso a los servicios públicos. Se procura identificar los principales factores que determinan la salud del niño y cuantificar el efecto de cada uno de ellos en cuanto al indicador bidimensional. Se adopta una estrategia secuencial para poder calcular un modelo lineal de dos ecuaciones con términos de error correlacionado. Un hallazgo importante es que las variables geográficas y culturales son factores determinantes significativos del estado de nutrición, y que las características antropométricas de la madre desempeñan un papel considerable. Se emplean datos de una encuesta demográfica y de salud de más de 3. 000 niños.

Recent insights into xerogel and aerogel mineral composites for CO 2 mineral sequestration

Supercritically dried composites have already been analysed and proposed as carbon dioxide sequesters. However, the economical and energetic costs of the supercritical drying process had to be re-evaluated, and were eventually found not to enhance the feasibility of the proposed route for CO2 mineral sequestration. Different composites series were synthesised with the only difference being the drying method. The structures of the porous matrix were characterised as well as their ability to capture CO2. The first results showed that the xerogel matrix is as good a host as the aerogel one, and also avoids expensive procedures such as supercritical drying for sample preparation without losing CO2 capture capacity and enhancing the efficiency of the whole carbon sequestration process. In this case, the sample preparation was simplified as much as possible, with the aim of reducing energetic and economic costs. Although good carbonation efficiencies were obtained with these cheap samples, the first results showed that previous high carbonation efficiencies could not be repeated.Junta de Andalucía TEP115Ministerio de Ciencia e Innovación PIA42008-3

Ecologically Designed Sanitary Sewer Based on Constructed WetlandsTechnology – Case Study in Managua (Nicaragua)

In developed countries the sanitation and treatment of urban wastewater is well sustained and technically solved by means of conventional pipe networksandsubsequentcentralizedtreatments.However,developingcountries lack these infrastructures and are in need of sustainable, decentralized and economically viable solutions for the disposal of their urban wastewaters. In addition to this, there are situations where the demands of conservation of naturalspacesdonotallowintensiveconstructiveproceduresandwhichforce the implementation of sanitary engineering with less environmental impact. We present the Ecological Wastewater Sewer (EWS), an ecological urban sewerage system that simultaneously transports wastewater and improves its quality.Thisinnovativetechnologyisanalternativetoconventionalsanitation piping that has minimal environmental impact. It is based on a successful previous work for the improvement of artificial wetlands in a pilot scheme andatfull-scaleonatestsite.TheEWSisachannel-shapeddevicethatrelies on the application of two key developments: a carefully designed cornered stones layout, and the creation of a natural aeration system. This way, it acts as a separating sewage system that guarantees the presence of a chamber of circulating air within the transportation unit, favouring permanent aerobic conditions in the upper levels of the mass of wastewater. Furthermore, its capacity to set tle suspended solids allows the EWS to be used as a sedimentor in water purification processes. A real-life application of this system proved successful in the sanitation of a district of Managua (Nicaragua). Working with a 100-metre-long street of 20 one-story houses, the system is reported to still be in full operating order after six years. The conclusions and results drawn from its monitoring are meticulously explained in our paper, as well astherecommendations&guidelinesforthedesignofmoreEWSunits,with aim to the popularization of this affordable, efficient and green approach to wastewater sanitation.Andalusian International School of Water Engineering, City hall of SevilleCooperation Office at the University of Sevill

Maximal slicings in spherical symmetry: local existence and construction

We show that any spherically symmetric spacetime locally admits a maximal spacelike slicing and we give a procedure allowing its construction. The construction procedure that we have designed is based on purely geometrical arguments and, in practice, leads to solve a decoupled system of first order quasi-linear partial differential equations. We have explicitly built up maximal foliations in Minkowski and Friedmann spacetimes. Our approach admits further generalizations and efficient computational implementation. As by product, we suggest some applications of our work in the task of calibrating Numerical Relativity complex codes, usually written in Cartesian coordinates.Comment: 25 pages, 6 figure

La organización de eventos como herramienta de comunicación en la gestión de marcas. Estudio de su uso en marcas de bebidas

La organización de eventos se ha visto impulsada de forma muy importante en los últimos años como herramienta de comunicación. Las promociones y presentaciones de producto se han puesto de moda desde que son una forma muy eficaz de acercarse al consumidor de una manera directa y en el momento en el que está más receptivo. Esto está provocando la creación de nuevas tendencias de gestión de marca a la hora de comunicar, tendencias donde las marcas buscan un buen posicionamiento en el mercado y la mente del consumidor por lo que “son” y no sólo por sus productos o servicios. La gestión de marca siempre debe estar reinventándose y adaptándose a la situación en la que se encuentra. La realidad es que estamos en un contexto cambiante marcado por los gustos de los consumidores, que cada vez buscan más el ser partícipes de las marcas y de su creación. Los públicos de las organizaciones y empresas están en constante búsqueda de vivir experiencias y dispuestos a interactuar, relacionarse, sentir y vivir con las marcas, empresas y sus productos. Los eventos son, por lo tanto, una herramienta muy eficaz y adecuada para generar estas experiencias de marca. Una buena gestión de marca no se lleva a cabo sólo con buenas ideas, también hace falta una excelente planificación que permita alcanzar los objetivos planteados dentro de la estrategia comunicativa. Los recursos tecnológicos con los que contamos actualmente son una gran ventaja a la hora de mejorar las experiencias con la marca en la organización de eventos, al igual que lo son las redes sociales. Conocer todas las posibilidades que hay para crear experiencias positivas entre la marca y el consumidor a través de los eventos y saber aprovechar la eficacia de la misma son algunas de las estrategias que siguen las marcas que han alcanzado el verdadero éxito. Por ello esta investigación se centra en el estudio y análisis de casos exitosos de gestión de marcas de bebidas vinculadas a la organización de eventos.Grado en Publicidad y Relaciones Pública
