The impact of urban development on aquifers in large coastal cities of West Africa: Present status and future challenges
2018
Abstract This paper investigates the coastal cities of Abidjan, Cotonou, Lagos and Douala in West Africa. Published data on these areas were aggregated in order to compare the urban development of some African huge cities and assess their impacts on groundwater. Those urban centers have experienced an exponential demographic expansion since the 1950s, with increased population densities and a geographical coverage expansion as well. The Continental Terminal aquifer, major groundwater resource taped in this region by the national water companies and local populations, shows a continuous downward trend in piezometric levels. Concerning water quality, the evolution up to the current state (sal…
Plant-wide modelling in wastewater treatment: showcasing experiences using the Biological Nutrient Removal Model
2020
Abstract Plant-wide modelling can be considered an appropriate approach to represent the current complexity in water resource recovery facilities, reproducing all known phenomena in the different process units. Nonetheless, novel processes and new treatment schemes are still being developed and need to be fully incorporated in these models. This work presents a short chronological overview of some of the most relevant plant-wide models for wastewater treatment, as well as the authors' experience in plant-wide modelling using the general model BNRM (Biological Nutrient Removal Model), illustrating the key role of general models (also known as supermodels) in the field of wastewater treatment…
DESIGNING & PILOTING ONLINE TESTS AS PART OF A TEACHER COMPETENCE ASSESSMENT
2019
Approaches for competence assessment are becoming increasingly important to plan school development goals, especially during complex educational changes. This paper outlines authors’ experience and recommendations from the designing and piloting of teacher online tests as part of a wider competence management process. A developed theoretical model of a universal teacher competence profile is presented. Tests represent four thematic parts related to teacher performance in classroom to facilitate: student cognitive activation, student self-regulation, student collaboration, and leveraging digital. Test questions were developed based on a framework of teacher performance assessment that consis…
Learning from the past in the COVID-19 era: rediscovery of quarantine, previous pandemics, origin of hospitals and national healthcare systems, and e…
2020
Abstract After the dramatic coronavirus outbreak at the end of 2019 in Wuhan, Hubei province, China, on 11 March 2020, a pandemic was declared by the WHO. Most countries worldwide imposed a quarantine or lockdown to their citizens, in an attempt to prevent uncontrolled infection from spreading. Historically, quarantine is the 40-day period of forced isolation to prevent the spread of an infectious disease. In this educational paper, a historical overview from the sacred temples of ancient Greece—the cradle of medicine—to modern hospitals, along with the conceive of healthcare systems, is provided. A few foods for thought as to the conflict between ethics in medicine and shortage of personne…
The digitized curriculum: voices and silences in the publishing field
2015
En este artículo se analiza la posición, de algunas de las editoriales presentes en la Comunidad Valenciana, sobre la migración hacia formatos digitales del libro de texto utilizado en centros educativos de niveles no universitarios. Con una metodología mixta se estudian tres dimensiones implicadas en el proceso: la estrategia tecnológica, la pedagógica y la comercial mediante una serie de entrevistas, encuestas, grupos de discusión y análisis de documentos. Entre los resultados alcanzados destaca la gran heterogeneidad de formatos, soportes y marcas; la necesidad de equipos pedagógicos de asesoramiento en las editoriales; la competencia de productos digitales del profesorado y el silencio …
Non-convex power allocation games in MIMO cognitive radio networks
2013
Consideramos un escenario de reparto del espectro, basado en la detección, en una red de radio cognitiva MIMO donde el objetivo general es maximizar el rendimiento total de cada usuario de radio cognitiva optimizando conjuntamente la operación de detección y la asignación de potencia en todos los canales, bajo una restricción de interferencia para los usuarios primarios. Los problemas de optimización resultantes conducen a un juego no convexo, que presenta un nuevo desafío a la hora de analizar los equilibrios de este juego. Con el fin de hacer frente a la no convexidad del juego, utilizamos un nuevo concepto relajado de equilibrio, el equilibrio cuasi-Nash (QNE). Se demuestran las condicio…
Frequency of co‐teaching in different teacher categories
2010
Co‐teaching – or the use of more than one teacher in a classroom – has been commonly recommended as a means to promote inclusive education. The aim of the present study was to survey the actual frequency of co‐teaching among different teacher categories in the comprehensive school level in one Finnish city. The data were collected through a questionnaire answered by two representative samples of teachers including 117 resource room teachers in the first survey, and 317 teachers of various teacher categories in the second. The results showed that co‐teaching was a widespread phenomenon among resource room teachers and special class teachers but less frequent among other teacher groups. Overa…
From job demands and resources to work engagement, burnout, life satisfaction, depressive symptoms, and occupational health
2016
This study investigated the cross-lagged associations between work engagement and burnout, and life satisfaction and depressive symptoms, their demands (i.e., workload) and resources (i.e., servant leadership, self-efficacy, resilience) and relationships with occupational health outcomes (i.e., recovery, number of mental health diagnoses, workaholism). This study is a part of an ongoing Occupational Health Study in which 1 415 employees (586 men, 829 women) were followed twice during two years 2011–12 through their occupational health services. The participants filled in a questionnaire on their work engagement, burnout symptoms, well-being, personal and work environmental resources and dem…
Estructura de la bolsa española e introducción del mercado de activos derivados sobre el IBEX-35
2001
-Jose.E.Farinos@uv.es -Matilde.Fernandez@uv.es La controversia acerca de si la implantación y negociación de activos derivados afecta a la estabilidad de los respectivos mercados de contado perdura desde hace más de dos décadas. En este trabajo abordamos la problemática anterior desde una nueva perspectiva. Concretamente, analizamos el impacto que sobre la estructura del mercado bursátil ha podido tener la introducción de los mercados de activos derivados sobre el IBEX-35. Para ello, definimos e identificamos la estructura del mercado bursátil para el periodo de estudio, y, a continuación, analizamos el efecto que sobre la misma ha tenido la aparición de los nuevos mercados de derivados. Nu…
Los plazos para interponer recursos y de determinados procedimientos y actos tributarios durante el Estado de Alarma.
2020
[EN] Royal Decree 463/2020, of March 14, declared the state of alarm as a consequence of COVID-19. From this declaration, a series of royal decree-laws have followed one another that have introduced a series of changes in the financial system to adapt the tax obligations to the health crisis situation. In this sense, the deadlines for filing resource, the forms and deadlines for filing and paying declarations and self-settlement have been modified, as well as certain procedures and acts while this exceptional regime lasts. In this study we are going to analyze the adoption of these measures and their accommodation in Tax Law.
