Effects of Vacation RentalWebsites on the Concentration of Tourists—Potential Environmental Impacts. An Application to the Balearic Islands in Spain

The concentration of tourists at certain times of the year can damage sensitive environments. The use of peer-to-peer vacation rental websites has increased greatly during the last decade. This system could either reduce seasonality in touristic destinations where the tourist activity takes place throughout the year at a lower price or on the contrary, it could increase the number of visitors at certain times of the year even more. This paper intends to analyze the effect that these platforms have on tourism seasonality in order to calculate if they help reduce or increase the pressure on the destinations. To do so, the Gini Index has been applied to one of the main touristic spots in Europe, the Balearic Islands in Spain. The conclusion is that this type of accommodation has aggravated the problem, generating a greater concentration of tourists and a higher pressure on the resources of the islands.The authors would like to thank the financial support provided by the Government of Spain (ECO2013-44879-R) and the Regional Government of Andalucía (SEJ-393)

Transcranial Direct Current Stimulation (tDCS) Combined with Therapeutic Exercise and Cognitive Rehabilitation to Treat a Case of Burning Mouth Syndrome (BMS) Related Pain.

Burning Mouth Syndrome (BMS) is a multifactorial, chronic pain condition with neuropathic and psychogenic mechanisms. Cortical activation as well as sustained attention and executive functions have proven to be affected by chronic pain. The main objectives of this work were to test the efficacy of a multidimensional personalized pain treatment protocol and to investigate if the effects are based on psychophysical pain processing changes or cognitive effects. A 74-year-old female with 2 years of BMS received 10 sessions of a combined protocol of anodal left dorsolateral prefrontal cortex tDCS, cognitive therapy, and therapeutic exercise. The subjective perception of pain decreased by 47% after treatment but returned to the baseline at 45 days. No changes were found in objective pain measurements apart from a transient worsening of conditioned pain modulation. A large effect size was found in all functional scales, processing speed and executive control as well as sustained attention that persisted during follow-up. No changes in anxiety and depression were found. A multimodal therapeutic approach combining TDCS, cognitive rehabilitation and therapeutic exercise produces improved quality of life, disability and pain perception correlated with improvements in processing speed, executive control and sustained attention but independent of changes in psychophysical pain processing.post-print475 K

Electrochemical behavior of hybrid carbon nanomaterials: the chemistry behind electrochemistry

The unzipping of temperature-induced multi-walled carbon nanotubes (MWCNTs) to yield graphene nanoribbons (GNRs) has been studied. These carbon nanomaterials consisting of MWCNTs and unzipped MWCNTs have been synthesized, thoroughly characterized, and subsequently evaluated for electrochemical sensing. Three temperatures (55, 65 and 75 ºC) yielding three carbon nanomaterial termed as GNR-55, GNR-65 and GNR-75, respectively, were carefully studied. Interestingly, GNR-65 became the most suitable material for the electrochemical sensing of a wide range of model analytes displaying the best electrochemical response with independence of the analysed molecule. This electrochemical behaviour seems to be associated to the progress of the unzipping reaction that influences the balance between the Csp2/Csp3 ratio, the graphitic fraction and the type of functional groups introduced. These results revealed the importance of the temperature in the synthesis process, for tailoring carbon nanomaterials which could be used in a particular molecular detection application opening new opportunities for electrochemical sensing applications.This work has been Financial supported by the Spanish Ministry of Science and Innovation (CTQ2011-28135), the NANOAVANSENS program from the Community of Madrid (S2013/MIT-3029), the Spanish MINECO (ENE2013-48816-C5-5-R), the Government Aragon (Project DGA_ESF-T66 CNN) and the European Social Fund (ESF).

Pedagogías de Nuestramérica en intercambio : Diálogo entre las propuestas de las cátedras de formación pedagógica de la Universidad Federal de Minas Gerais (Brasil), de la Universidad Nacional de Asunción (Paraguay) y de la Universidad Nacional de La Plata (Argentina)

La ponencia se enmarca en el eje de trabajo sobre formación de grado y tiene como objetivo aportar al conocimiento del campo pedagógico del Sur a partir del intercambio entre temas, objetivos, estrategias metodológicas y prácticas que se están desarrollando en las cátedras de formación pedagógica de la Universidad Federal de Minas Gerais (Brasil), de la Universidad Nacional de Asunción (Paraguay) y de la Universidad Nacional de La Plata (Argentina). Se reconoce que las propuestas curriculares de las cátedras están conformadas por aspectos estructurales- formales y procesales- prácticos, como también por aspectos políticos que interactúan en el acontecer de los currículos en las instituciones educativas. Esto significa que el curriculum atraviesa varios niveles en su concreción: la de la propia disciplina o área de conocimiento de la cual proviene; la lógica con la que se organizan los contenidos a través de las redes conceptuales en la conformación del plan de estudios; la lógica propia con la cual el docente interpreta y reorganiza un contenido ya organizado. En este sentido, esta ponencia se propone conocer cuáles son las características de las propuestas de formación pedagógica en diferentes facultades de educación de algunas universidades de América del Sur. A partir de estos objetivos, la ponencia despliega el intercambio en un diálogo en torno a: I) la definición disciplinar, II) la organización temática y los autores trabajados, III) los presupuestos teóricos y metodológicos, IV) las estrategias de enseñanza y las propuestas de aprendizaje, V) el lugar de la asignatura en el plan general de la carrera, y VI) su contribución al proceso de formación. Las conclusiones organizan los aportes en torno a las características compartidas como así también diferenciales de las tres propuestas de formación pedagógica. La UNA en Paraguay ofrece una mirada humanista, mientras que la UFGM es una propuesta marcadamente intervencionista, y finalmente, la UNLP presenta una mirada analítica. Desde esta diversidad de posturas, las propuestas definen intereses compartidos; así, reconocen la interdisciplinariedad de la Pedagogía, puesto que integra y construye su propio conocimiento a la luz de la interpenetración de los contenidos y métodos de otros campos del conocimiento. Los saberes provenientes de otras ciencias y disciplinas le ayudan a comprender lo que es la educación. Por otra parte, las propuestas de formación pedagógica reconocen que el objetivo de la Pedagogía se orienta a formar una actitud crítica, a través de favorecer el análisis y la reflexión de las prácticas pedagógicas en los ámbitos sociales y educativos. Asimismo, las propuestas acuerdan en que el fin de la formación pedagógica es el compromiso con la realidad, es por ello que declaran formar profesionales de la educación comprometidos con un proyecto histórico de transformación social, con los derechos humanos y con la convivencia democrática, y con la preservación y protección del medio ambiente. Es así que las cátedras comparten la elección del debate como una de las estrategias metodológicas utilizadas, buscando con ello desarrollar instancias de discusión, debate, que propicien la argumentación y contra-argumentación, favoreciendo la curiosidad epistemológica.Evento realizado junto con las I Jornadas de Intercambio de Pedagogías del SurFacultad de Humanidades y Ciencias de la Educació

Desde estos presupuestos, reconstruimos y articulamos una propuesta para la educación del pensamiento y el carácter (ethos) crítico en las redes sociales

Aligned copper nanowires as a cut-and-paste exclusive electrochemical transducer for free-enzyme highly selective quantification of intracellular hydrogen peroxide in cisplatin-treated cells

The role and reliable quantification of intracellular hydrogen peroxide during cancer therapy constitutes an unexplored and fascinating application. In this work, we report the fabrication of vertically aligned copper nanowires (v-CuNWs) using electrosynthesis on templates, and their application as a cut-and-paste exclusive and flexible electrochemical transducer. This easily adaptable electrodic platform is demonstrated for a fast, simple and free-enzyme selective quantification of intracellular hydrogen peroxide in Cisplatin-treated human renal HK-2 cells. The v-CuNWs sensor was compared with an HRP-enzyme-based biosensor showing excellent correlation and indicates the good selectivity and analytical performance of the v-CuNWs. This sensing approach opens novel avenues for monitoring cell death processes and shows the potential of H2O2 as a cellular damage biomarker, with a clear potency for further developments for in vitro diagnosis and its implication in cancer therapy.Comunidad de MadridMinisterio de Economía y CompetitividadMinisterio de Ciencia e Innovació

Bordetella hinzii Endocarditis, A Clinical Case Not Previously Described

Objective: To review infections by Bordetella hinzii. Materials and methods: A 79-year-old male patient, with a chronic aortic valve biological prosthesis, presented to hospital because of fever. First examinations were normal. However, 72 hours later B. hinzii was isolated in blood cultures, and so meropenem was prescribed. Nevertheless, fever and B. hinzii bacteraemia were still present 7 days later. Results: The transoesophageal echocardiogram revealed an enlarged image suggesting a periprosthetic abscess, confirmed with a PET-CT scan. The patient was sent for cardiac surgery, and biopsy samples confirmed the presence of B. hinzii. Conclusion: There are very few cases of B. hinzii infection in humans. Ours is the first described case of B. hinzii endocarditis

Dense strontium hexaferrite-based permanent magnet composites assisted by cold sintering process

[EN] The use of rare-earth-based permanent magnets is one of the critical points for the development of the current technology. On the one hand, industry of the rare-earths is highly polluting due to the negative environmental impact of their extraction and, on the other hand, the sector is potentially dependent on China. Therefore, investigation is required both in the development of rare-earth-free permanent magnets and in sintering processes that enable their greener fabrication with attractive magnetic properties at a more competitive price. This work presents the use of a cold sintering process (CSP) followed by a post-annealing at 1100 °C as a new way to sinter composite permanent magnets based on strontium ferrite (SFO). Composites that incorporate a percentage ≤ 10% of an additional magnetic phase have been prepared and the morphological, structural and magnetic properties have been evaluated after each stage of the process. CSP induces a phase transformation of SFO in the composites, which is partially recovered by the post-thermal treatment improving the relative density to 92% and the magnetic response of the final magnets with a coercivity of up to 3.0 kOe. Control of the magnetic properties is possible through the composition and the grain size in the sintered magnets. These attractive results show the potential of the sintering approach as an alternative to develop modern rare-earth-free composite permanent magnets.This work has been supported by the Ministerio Español de Ciencia e Innovación (MICINN), Spain, through the projects MAT2017-86540-C4-1-R and RTI2018-095303-A-C52, and by the European Commission through Project H2020 No. 720853 (Amphibian).
