Reflexiones epistemológicas en torno a la interactividad de la era digital
Este trabajo es una reflexión sobre las características epistemológicas que subyacen en el proceso de interactividad que se viene experimentando en el mundo occidental desde aproximadamente la segunda mitad del siglo XX, con el predominio de las nuevas tecnologías de información y comunicación (NTIC), a través de la revisión de las posiciones de algunos de los principales teóricos de las comunicaciones, como McLuhan o de Kerckhove, y planteándonos algunas interrogantes en relación a las ventajas y desventajas que el acceso, el manejo y el control de las NTIC suponen.In this paper, we reflect about the epistemological characteristics underlying on the
interactivity process taking place in the Western Civilization since the second half of the
twentieth century with the predominance of the new information and communication
technologies. Also, we ask ourselves about the advantages and the disadvantages that people
have in the access, management and control of the new information and communication
technologies. For that reason, we will review the opinions of some of the main
communication and information technology theorists like McLuhan and de Kerckhove
Reactivation of a hyperextended rift system: the Basque‐Cantabrian Pyrenees case.
This contribution investigates the role of a hyperextended rift system in the formation of the Basque-Cantabrian Pyrenees by discussing their present-day architecture as well as the inherited rift template. Moreover, this work attempts to decipher the onset of reactivation of a hyperextended system and to discuss the related processes during collision. To carry out this study, two regional, crustal-scale cross-sections are presented that provide geological and geophysical information and interpretations across the Central and Western Basque-Cantabrian Pyrenees. Moreover, the two sections are restored back to the Cenomanian and Barremian, corresponding to the end of two independent rift stages respectively. The two sections document different structural styles observed along the orogenic belt. The Central section, involving the Iberian and European plates, shows a thin-skinned structural style, where the Upper Triassic salt acted as a decoupling level between the sedimentary cover and the underlying basement during both extension and reactivation. The Western section, by contrast, crosses only the Iberian plate (i.e., intra-plate section) and displays a hybrid situation showing both thin- and thick-skinned structural styles that were conditioned by the irregular distribution of Triassic salt. Extensional deformation was localised in the north (i.e., Bay of Biscay) and less important in the south. Despite compressional reactivation, the northern part of the Western section preserves its rift template, which provides key insights to restore the internal part of the Central section. In contrast to the Western section, the Central section shows stacked depocenters, resulting from overprinted Mesozoic rift events that had a first order control on the subsequent reactivation. This study corroborates the importance of rift inheritance during the onset of convergence by reactivating the most distal and weak part of the rift system (i.e., serpentinised mantle) before starting the collision phase. A key learning is that the understanding of the nature and distribution of decoupling levels at a crustal scale is fundamental to reconstruct the structural evolution during the formation and reactivation of a hyperextended rift system
Ecoturismo en Madre de Dios (Perú). Una propuesta de investigación
Se busca caracterizar las actividades ecoturísticas en el Perú, mediante el estudio comparativo y balance de dos experiencias ecoturísticas en las comunidades nativas amazónicas de Infierno en Tambopata y de Tayakome y Yomibato en el Manu, involucradas actualmente en la práctica del ecoturismo. De esta manera podrá establecerse en qué medida y forma el discurso ecoturístico es adoptado por las comunidades protagonistas y si realmente ejerce las funciones de desarrollo y sostenibilidad que le son adjudicadas

Manejo de la biodiversidad
El cuidado de la diversidad biológica, materia de estudio en las líneas siguientes, es un aspecto concerniente a los asuntos de estado y que debe ser asumido con preocupación y compromiso por las políticas de gobierno de los países.La diversidad biológica incluye la cantidad y variedad de organismos que hay en el planeta, en una región, en un país o en un lugar, así como el contenido genético que les dio origen, producto de millones de años de evolución y las complejas relaciones y funciones del medio ambiente con los organismos. Puede decirse que el conocimiento que se tiene sobre ella, a nivel local como mundial, es todavía incipiente. Los estudios más completos corresponden a los grupos de mamíferos, aves, anfibios, peces y plantas con flores.
 
Constraints Imposed by Rift Inheritance on the Compressional Reactivation of a Hyperextended Margin: Mapping Rift Domains in the North Iberian Margin and in the Cantabrian Mountains
Guided Bone Regeneration of an Atrophic Maxilla Using Heterologous Cortical Lamina
Alloplastic dental implants are currently the best way to replace lost teeth. In order to achieve good function and prognosis of dental implants, having bone and soft tissue to support them is necessary. When the amount of bone left is not enough to ensure the outcome of the implant, techniques such as shorts implants, zygomatic implants, or guided bone regeneration have been used. Even though autologous bone is mostly the 'gold standard,' other biomaterials such as xenografts have led to the reduction of the morbidity of treatments and to the improvement of the regeneration technique outcomes. We present a clinical case of severe atrophy of the maxilla in which we used different types of biomaterials: heterologous cortical lamina, xenograft and autologous bone, and microscrews
Active Commuting to School among Spanish Preschool Children: A Temporal Change Study between 2013 and 2017
Background: Active commuting to school may increase the total daily physical activity
and achieve health benefits among preschool children. Rates of active commuting to school among
Spanish children and adolescents have been widely analysed, while the rates of active commuting to
school among Spanish preschool children are unknown. Aim: The main objective of this study was
to examine the changes in the rates of active commuting to school in a sample of Spanish preschool
children between 3 and 6 years old from 2013 to 2017. Methods: Data were found from five studies
carried out across Spain. The study sample comprised 4787 preschool children (4.59 0.77 years old;
51% males). The overall changes in active commuting to school were assessed using multilevel
logistic regression analysis. Results: The rates of active commuting to school in Spanish preschool
children are around 52%, and the active commuting to school rates have stayed stable throughout
the period assessed (odds ratio from 0.40 to 0.58, all p > 0.05). Conclusion: In preschool children, the
present study obtained a favourable result on active commuting to school, showing a pattern stability
in the examined period similar to other ages. It will be of great importance to promote this behaviour
to obtain high levels of active commuting to school.Spanish Ministry of Economy, Industry and CompetitivenessEuropean

Ajuste del método de predicción del inicio de la estación polínica del plátano de sombra en Madrid y Córdoba
Ponencia presentada en: VI Congreso Internacional de la Asociación Española de Climatología celebrado en Tarragona del 8 al 11 de octubre de 2008.[ES]El objetivo de este estudio es mostrar el diseño y la evaluación de un sistema de predicción de
eventos de polen que causan efectos en la salud pública. La sensibilización al polen alérgico ha
aumentado en las últimas décadas. Las autoridades sanitarias prestan cada vez mayor atención
a este problema. Este estudio utiliza información palinológica y meteorológica ene le ámbito
territorial de la Comunidad de Madrid, en donde se ha diseñado un sistema de predicción del
inicio de la temporada de polinización del plátano como fruto de la colaboración entre AEMET
y la Conserjería de Sanidad de dicha Comunidad.[EN]Allergenic pollens originated health problems in a rising segment of population on developed
countries. Adequate forecast of extreme health related events such peaks or start of pollination
season could allow taking preventive measurement that reduce hospitalization cases and an
improvement in life conditions for patients. AEMET and partnership institutions are
developing models that would allow early warning to Health Authorities., Plane tree pollen is
one of the main causes of pollen relate allergies in Iberian Peninsula
