Interacción en las aulas de matemáticas de primaria de Reino Unido y España

La investigación en Educación Matemática se ha interesado por el análisis de la interacción entre un maestro de Primaria y sus alumnos cuando resuelven conjuntamente problemas en el aula (e.g., Sánchez et al., 2014). Los resultados obtenidos en estudios en España mostraron que el maestro promueve escasamente el razonamiento cuando resuelve problemas con sus estudiantes (Rosales et al., 2012). Por eso es de interés conocer qué sucede en otros países. En este trabajo se pretenden comparar los procesos que se explicitan durante la interacción de maestros de Primaria de Reino Unido y España cuando resuelven problemas similares con sus estudiantes

Vino bretado: límite entre su aceptación por su carácter “complejo” y su rechazo por considerarse “defectuoso” -perspectiva enmarcada dentro del sistema de gestión de calidad

ARTÍCULO PUBLICADO EN REVISTA EXTERNA. Una alteración particular de vinos es causado por levaduras del género Brettanomyces, defecto conocido como “bretado”. Esta particularidad se percibe tanto como un atributo positivo o negativo, dependiendo de los niveles de concentración de las sustancias responsables del olor (4-etilfenol 4EF, 4-etilguayacol 4EG). El objetivo del estudio fue determinar el nivel de percepción y aceptación de vinos con diferentes concentraciones de brett por parte de consumidores habituales de vino

Ultrathin composite polymeric membranes for CO2/N2 separation with minimum thickness and high CO2 permeance

The use of ultrathin films as selective layers in composite membranes offers significant advantages in gas separation for increasing productivity while reducing the membrane size and energy costs. In this contribution, composite membranes have been obtained by the successive deposition of approximately 1 nm thick monolayers of a polymer of intrinsic microporosity (PIM) on top of dense membranes of the ultra-permeable poly[1-(trimethylsilyl)-1-propyne] (PTMSP). The ultrathin PIM films (30 nm in thickness) demonstrate CO2 permeance up to seven times higher than dense PIM membranes using only 0.04 % of the mass of PIM without a significant decrease in CO2 /N2 selectivity.The research leading to these results has received funding from the EU FP7 Programme (FP7/2007–2013), under grant agreement number 608490, project M4CO2, Spanish MINECO and FEDER (MAT2016-77290-R) and the Aragon Government (T05 and E54).

Interdisciplinary discussions on palliative care among university students in Spain: giving voice to the social debate

Background: University students are the future professionals who will influence society. It is thus essential to improve students' understanding of palliative care (PC), especially those in the non-health field, to generate and encourage propitious opinions about PC. This study describes the perceptions of PC among university students from different disciplines. Method: Qualitative exploratory study using virtual focus groups (FGs) and design thinking (DT) approach. An intentional sample of students from various disciplines, universities and cities from Spain were selected. Numerous researchers from different fields were involved in the discussion of the final thematic analysis. Results: Four themes and seven subthemes were found: i) Students have an ambiguous understanding about PC; ii) PC is not a common issue for non-health students; ii) Students see PC as an important and necessary field; iii) Students build counter-narratives against PC myths, demonstrating PC brings key benefits into people's lives; iv) PC is a synonym of death. Conclusion: Despite the fact that students do not know much about PC, the topic easily arouses reflection and positive discussion. Through the conversations they find positive values and arguments against misunderstand- ing. Students from different disciplines could be the target of innovative educational initia- tives and the social debate on PC

Banco de La Concepción: A new Natura 2000 Marine Site off Canary Islands

The main objective of the LIFE+ INDEMARES project is to contribute to the protection and sustainable use of the biodiversity in the Spanish seas through the identification of valuable areas for the Natura 2000 Network. The Spanish Institute of Oceanography (IEO) has been in charge of implementing scientific surveys to map sensitive habitats of seven of the ten INDEMARES areas, and to determine the fisheries footprint over these areas. Banco de La Concepci´on is one of the areas chosen to be depicted in the frame of INDEMARES project. Located at 71 km to the NE of Lanzarote, at the coordinates 29º 55’ Latitude N and 12º 45’ Longitude W, Banco de la Concepci´on raises from 2,541 m up to its summit at 170 m deep. The biological richness of Banco de la Concepci´on is very influenced by the deep water up-welling phenomena, which create a high productivity, attracting a multitude of pelagic species, such as cetaceans, turtles, sharks, and tunas looking for food. In its vicinity, fishery resources such as goraz, anglerfish, and hakes, are abundant, and a rich invertebrate fauna cohabits in their bottoms. Banco de la Concepci´on is a traditional fishing area of oceanic pelagic species, and very good to catch demersal fish; it is highly visited by Galician and Portuguese drifters and long liners that fish in Mauritania, and mainly by the Andalusian longliners. In general, its main impacts are related to uncontrolled fishing pressure. The available information on the anthropogenic impact of the area was scarce, and its level of research was very poor as well, before INDEMARES project. Methodology approach complies with a multidisciplinary perspective, having described the area from geological, oceanographic, biological and fisheries points of view. Several surveys have taken place since 2009 to 2013 at Banco de La Concepci´on waters. Traps, longlines, beam trawls, benthic dredges and box corers have been used to sample benthic fauna. These last two, plus EM 3002 multibeam echosounder, PS 18 parametric sub bottom profiler, EA600 monobeam sounder, Seapath 200 positioning sensor and SV Plus sound velocity calibration sensor were used to make a geophysical study which provides a range of environmental factors. CTD was used to depict physical conditions of the water column. Finally, Remote Operated Vehicle Liropus 2000 and different photogrammetric tugged sleds were used to make a great effort of visual sampling. Data from VMS (Vessel Monitoring System) were used, combined with interviews to users (fishers), to describe the fishery uses in the area. Results from all this field work provide enough information for the administrations to establish a new Natura 2000 area, trying to reconcile protection of biodiversity and artisanal local economic activities. This establishment should take place at the end of a process of public consultation to stakeholders which is taking place in the present and which will help to shape the future Management Plan which will give details about permitted and prohibited uses

Sensitive Habitats and fishing footprint off Canary Islands seamounts Amanay and El Banquete

The main objective of the LIFE+ INDEMARES project is to contribute to the protection and sustainable use of the biodiversity in the Spanish seas through the identification of valuable areas for the Natura 2000 Network. The Spanish Institute of Oceanography (IEO) has been in charge of implementing scientific surveys to map sensitive habitats of seven of the ten INDEMARES areas, and to determine the fisheries footprint over these areas. Sur y Oriente de Fuerteventura y Lanzarote is one of the areas chosen to be depicted in the frame of INDEMARES project, although the study about benthic habitats and fishery footprint carried by IEO has restricted to Amanay and El Banquete Seamounts. El Banquete really is the extension of southern continental shelf while Amanay seamount is located at 25 km from Jand´ıa Lighthouse (S of Fuerteventura) and 55 km from Las Palmas de Gran Canaria, at the coordinates 28º 07’ Latitude N and 14º 44’ LongitudeW, both volcanic buildings raise from more than 2,000 m up to their summits at 25-30 m deep, separated by a 1.500 m deep channel. The biological richness of Amanay and El Banquete seamounts is very influenced by the deep water up-welling phenomena, which create a high productivity, attracting a multitude of pelagic species, such as cetaceans, turtles, sharks, and tunas looking for food. There is also a high influence from Saharian up-welling. Both the seamounts tops and their vicinities are often visited by a large artisanal local fishing fleet which profits of their fishery resources; also a rich invertebrate fauna cohabits in their bottoms. In general, its main impacts are related to uncontrolled fishing pressure, and maritime navigation. The available information on the anthropogenic impact of the area was scarce, and its level of research was very poor as well, before INDEMARES project. Methodology approach complies with a multidisciplinary perspective, having described the area from geological, oceanographic, biological and fisheries points of view. Several surveys have taken place since 2009 to 2013 at Amanay and El Banquete waters. Traps, longlines, beam trawls, benthic dredges and box corers have been used to sample benthic fauna. These last two, plus EM 3002 multibeam echosounder, PS 18 parametric sub bottom profiler, EA600 monobeam sounder, Seapath 200 positioning sensor and SV Plus sound velocity calibration sensor were used to make a geophysical study which provides a range of environmental factors. CTD was used to depict physical conditions of the water column. Finally, different photogrammetric tugged sleds were used to make a great effort of visual sampling. Data from VMS (Vessel Monitoring System) were used, combined with interviews to users (fishers), landing samplings and scientific observation onboard, to describe the fishery uses in the area

Demersal and epibenthic communities of sedimentary habitats in the Avilés Canyon System, Cantabrian Sea (NE Atlantic)

The aim of this study was to describe the epibenthic and demersal communities of the Avilés Canyon System (ACS) in relation to the environmental variables that characterize their biotope. ACS (Cantabrian Sea, NE Atlantic) was recently included in the Natura 2000 network as a Site of Community Importance (SCI). Data of faunal biomass derived from 6 surveys carried out using beam trawl and otter trawls in 2009 and 2010 within INDEMARES and ERDEM projects. Data were divided into two groups to obtain information about the two ecological compartments: benthic and demersal. The total number of species used in this analysis ascended to 116 in the case of benthic organisms and 110 in the case of demersal. Hierarchical clustering analysis was applied to obtain groups of samples similar in terms of species composition for the two ecological components. Depth was the main discriminating factor for grouping hauls, showing high consistency of bathymetric range independently from the compartment examined. Six groups were identified by depth as follows: medium shelf (∼100–200 m), external shelf (∼150–300m), shelf break (∼300–400 m), upper-slope (∼500–700 m), upper middle-slope (∼700–1100 m), and lower-middle-slope (1200–1500 m). SIMPER analysis on biomass values was performed to determine the structure of the faunal assemblages observed for each group in both compartments. Using biomass values for the analysis allowed for the exploration of groups playing important roles in ecosystem functioning and energy fluxes taking place on the sedimentary bottom of this SCI. Finally, CCA analysis revealed that the main environmental drivers were depth, broad scale bathymetric position index (BPI), near-bottom salinity, sedimentary type, and dynamics related variables (Q50 phy and So). This study gives an inventory of the soft bottom assemblages along a very wide depth range (100–1500 m) inside a SCI, linking both epibenthic and demersal communities with the biotope preferences. This study contributes to fundamental knowledge on soft-bottom communities as a pre-requisite, necessary for the next steps in terms of management framework in the SCI

Combining interdisciplinarity and creative design - A powerful strategy to increase palliative care awareness within a university community

Society’s understanding of palliative care has room for improvement. Although the World Health Organisation highlighted palliative care as a human right, many people still lack access to this crucial form of treatment. The paucity of understanding and social discussion surrounding palliative care has, moreover, negatively impacted its development and implementation. This study therefore aims to construct a strategy that will empower a specific community to solve their own palliative care-related misunderstandings. Using Participatory Action Research and Design Thinking methodologies and adopting the strategy of Public Engagement in Responsible Research and Innovation, a design group worked for three months through five virtual focus groups. Moving through the phases of empathizing, defining, ideation, prototyping, and testing, the design group generated 33 ideas to address palliative care-related problems. Ideas related to self- learning, the use of technology, and the exchange of personal experiences are highlighted as innovative ways to promote palliative care. The design group adopted a variety of strategies, used disruptive tools, and created and tested rapid prototypes to discover novel solutions. This method of working, centred on interdisciplinarity and creativity, presents an efficient way to involve the members of a community in solving their own problems

Geomorphology of the Avilés Canyon System, Cantabrian Sea (BayofBiscay)

The Avilés Canyon System (ACS) is a complex, structurally-controlled canyon and valley system constituted by three main canyons of different morphostructural character. They are, from east to west: La Gaviera Canyon, El Corbiro Canyon and Avilés Canyon. In addition to this ACS, a new canyon has been surveyed: Navia Canyon. We present for the first time a high resolution multibeam map showing with great detail the morphological and structural complexity of this segment of the Cantabrian margin. ACS presents a tectonic imprint marked by NW-SE, NNE-SSW and E-W structures. The morphology of their reaches as well as their single mouth, in addition to some rock dredges in their major valleys, demonstrates active down-slope flushing. The continental shelf shows a flat, uniform slope with local and well defined rock outcrops south of Aviles Canyon head. Sedimentary zones are limited, showing thin unconsolidated sedimentary cover. Strong continental margin water dynamics avoid thicker sediment deposition, being littoral sedimentary dynamics responsible for transport to the canyons heads and conduit to the Biscay Abyssal plain. Biscay Abyssal Plain shows evidence of a strong westward current affecting the surveyed strip of this more than 10 km wide plain. Presence of two parallel deep sea channels, erosive scarps, and erosion of gully divides on the lower slope, may indicate that this is part of the distal fan at the termination of the large turbiditic system fed by Cap Ferret, Capbreton and other large canyons (Santander, Torrelavega, Lastres and Llanes) to the west of ACS.Instituto Español de OceanografíaVersión del edito
