A User-Centered Chatbot (Wakamola) to Collect Linked Data in Population Networks to Support Studies of Overweight and Obesity Causes: Design and Pilo…
2021
[EN] Background: Obesity and overweight are a serious health problem worldwide with multiple and connected causes. Simultaneously, chatbots are becoming increasingly popular as a way to interact with users in mobile health apps. Objective: This study reports the user-centered design and feasibility study of a chatbot to collect linked data to support the study of individual and social overweight and obesity causes in populations. Methods: We first studied the users' needs and gathered users' graphical preferences through an open survey on 52 wireframes designed by 150 design students; it also included questions about sociodemographics, diet and activity habits, the need for overweight and o…
European leaders unmasked: Covid-19 communication strategy through Twitter
2020
[EN] The coronavirus disease Covid-19 (SARS-CoV-2) pandemic is exacting a huge toll on individuals, families, communities, and societies across the world. The study of public communication is a key aspect for slowing the spread of the virus and therefore reducing the death rate. This article analyses political leaders' crisis communication during the Covid-19 pandemic of the most affected European countries, Boris Johnson (United Kingdom), Emmanuel Macron (France), Pedro Sanchez (Spain) and Giuseppe Conte (Italy), in addition to Tedros Adhanom as a representative of the World Health Organisation (WHO) and Ursula Von der Leyen President of the European Union (EU). The study focuses on the vi…
Opportunities and Hazards of the Internet for Students with Intellectual Disabilities: The Views of Pre-Service and In-Service Teachers
2019
Teachers´ perceptions about the benefits and safety of the Internet for students with intellectual disabilities may affect their willingness to promote online access for this group. Therefore, the purpose of this study was to explore and compare the views of pre-service and in-service teachers concerning the opportunities and hazards that the Internet has for students with intellectual disabilities. A cross-sectional survey design was conducted with the participation of 582 pre-service and in-service teachers from south-eastern Spain. Findings reveal that teachers have great concerns about the use of the Internet by students with ID, with higher ratings for perceived online risks than for o…
Estimating Patient Empowerment and Nurses' Use of Digital Strategies: eSurvey Study.
2021
Patient empowerment is seen as the capability to understand health information and make decisions based on it. It is a competence that can improve self-care, adherence and overall health. The COVID-19 pandemic has increased the need for information and has also reduced the number of visits to health centers. Nurses have had to adapt in order to continue offering quality care in different environments such as the digital world, but this entails assessing the level of their patients’ empowerment and adapting material and educational messages to new realities. The aim of this study is, on the one hand, to assess nurses’ use of digital resources to provide reinforcing information to their patie…
La dimensión ética y ciudadana del Aprendizaje Servicio : una apuesta por su institucionalización en la Educación Superior
2018
El presente artículo es una reflexión acerca del valor ético y cívico de los proyectos de Aprendizaje Servicio, a partir de argumentos y pruebas procedentes de un proceso de revisión bibliográfica, pero elaborando asimismo una fundamentación propia a partir de un análisis hermenéutico de esta metodología de enseñanza-aprendizaje. Se concluye que los proyectos de Aprendizaje Servicio favorecen desde la práctica una síntesis de la ética del cuidado y de la justicia, y contribuyen a una nueva definición del concepto de educación, en tanto que fomentan el aprendizaje significativo y revitalizan la dimensión ética y ciudadana de los procesos educativos, en sintonía con las propuestas de desarrol…
Universities' Reporting on SDGs: Using THE Impact Rankings to Model and Measure Their Contribution to Sustainability
2021
Higher education institutions (HEIs) have voiced growing concerns about sustainability issues since Agenda 2030 was approved, but this is not enough for societal stakeholders seeking and delivering innovation and excellence. The 17 Sustainable Development Goals (SDGs) were adopted by all UN Member States in 2015 as a universal call to action, and pose a challenge for HEIs as for the efforts made to fulfill them and knowing how to assess their performance. However, the metric management system implemented by HEIs quickly led to rankings emerging, which compare HEIs to metrics not related to the sustainability dimensions of the 17 SDGs. The main aim of the paper is to assess the level of repo…
Historia urbana y mezzogiorno de Italia en la Edad Moderna: propuesta de un cuestionario
1998
The history of urbanization has barely been analyzed for the Mezzogiorno in Italy. This has partly been due to the persistence of stereotypes in Italian historiography, and partly due to the current definition of city functions. The article results from a meeting of specialists in Early Modern southern Italian history organized to undertake the rigorous and detailed study of the common features and the differences within the urban systems of the Mezzogiorno, in order to synthesize the specific character of urbanization in southern Italy over the long term. The author outlines the main areas under study and establishes its methodological foundations and first hypotheses.
Outdoor microalgae-based urban wastewater treatment: recent advances, applications and future perspectives
2021
[EN] Although microalgae-based wastewater treatment has been traditionally carried out in extensive waste stabilization ponds, recent trends focus on the use of microalgae to apply the circular economy principles in the wastewater treatment sector due to the capacity of algae to absorb carbon dioxide while recovering nutrients from sewage. To this aim, the development of new intensive microalgae-based systems with higher efficiency and level of process control is required. Results obtained for these systems at lab scale are generally promising. However, upscaling to outdoor conditions is often uncertain. Some advances have been made in terms of applying open systems at large scale. However,…
Continuous 3-year outdoor operation of a flat-panel membrane photobioreactor to treat effluent from an anaerobic membrane bioreactor
2020
[EN] A membrane photobioreactor (MPBR) plant was operated continuously for 3 years to evaluate the separate effects of different factors, including: biomass and hydraulic retention times (BRT, HRT), light path (Lp), nitrification rate (NOxR), nutrient loading rates (NLR, PLR) and others. The overall effect of all these parameters which influence MPBR performance had not previously been assessed. The multivariate projection approach chosen for this study provided a good description of the collected data and facilitated their visualisation and interpretation. Forty variables used to control and assess MPBR performance were evaluated during three years of continuous outdoor operation by means …
Improving membrane photobioreactor performance by reducing light path: operating conditions and key performance indicators
2020
[EN] Microalgae cultivation has been receiving increasing interest in wastewater remediation due to their ability to assimilate nutrients present in wastewater streams. In this respect, cultivating microalgae in membrane photobioreactors (MPBRs) allows decoupling the solid retention time (SRT) from the hydraulic retention time (HRT), which enables to increase the nutrient load to the photobioreactors (PBRs) while avoiding the wash out of the microalgae biomass. The reduction of the PBR light path from 25 to 10 cm increased the nitrogen and phosphorus recovery rates, microalgae biomass productivity and photosynthetic efficiency by 150, 103, 194 and 67%, respectively.The areal biomass product…
