Abstract

In the face of climate change and resource scarcity, energy supply systems are on the verge of a major transformation, which mainly includes the introduction of new components and their integration into the existing infrastructures, new network configurations and reliable topologies, optimal design and novel operation schemes, and new incentives and business models. This revolution is affecting the current paradigm and demanding that energy systems be integrated into multi-carrier energy hubs. It is highly increasing the interactions between today’s energy systems at various scales and future intelligent energy systems, which are able to incorporate an increasing amount renewable energy sources. This transformation is also accommodating active participation of end-users as responsive prosumers at different scales which in turn helps to reduce energy costs and to mitigate carbon footprints.This book covers the mentioned promising and dynamic areas of research and development, and reports on contributions in design, control and optimization of integrated energy systems. The contents of the book which are gathered based on the accepted articles in the special issue on Advances in Integrated Energy systems Design, Control and Optimization also covers a variety of topics, ranging from operation and control of small-scale electrical networks to the complex energy systems design and planning.

Mapa de Investigación sobre el Aprendizaje

El Mapa de Investigación sobre del Aprendizaje ayuda a los líderes de la educación, los diseñadores de políticas y los desarrolladores de tecnología a acceder rápidamente a los hallazgos de las investigaciones científicas sobre aprendizaje en los diferentes temas y disciplinas que pueden ser de utilidad para la toma de decisiones informadas sobre como aprenden las personas.

El Mapa de Investigación ofrece una manera sencilla de ver, buscar y ordenar artículos de investigación, y ayuda a descubrir nuevos temas de interés. Si queremos visualizar información sobre el aprendizaje de las matemáticas, explore el tema de Math Learning para encontrar enlaces a artículos de investigación y expertos en el campo. 

El mapa fue construido usando datos de más de 100,000 artículos publicados entre 2007 y 2016, encontrados en 184 revistas académicas de la base de datos Web of Science. Se analizó el registro bibliográfico (título, palabras clave, autor, referencias citadas y resumen) para cada artículo y se creó una red de acoplamiento bibliográfico, para vincular artículos compartiendo al menos dos referencias comunes.

A continuación, se utilizo un algoritmo para detectar grupos de artículos con enlaces densamente compartidos. En la vista de red, los artículos pertenecientes a la misma materia se agrupan en nodos o círculos, que llamamos “temas”. El tamaño del círculo es proporcional al número de artículos que contiene. Del mismo modo, la anchura de un arco de borde de color en la vista es proporcional al número de artículos que contiene. En ambas vistas de mapa, el grosor de las líneas (o acordes) entre los temas indica cuán fuertemente están conectados. Se utiliza el mismo algoritmo a los artículos de cada tema para dividirlos en subtemas.

Después se revisaron los documentos más citados y representativos de cada tema y subtemas para crear etiquetas y descripciones. El análisis de datos y la visualización se completó utilizando BiblioTools y D3.

Tres formas de navegar por la herramienta:

  1. Consultar las vistas interactivas, que muestran temas de investigación y subtemas, y cómo se conectan entre sí. Para ello haga clic en un tema para ver los artículos de investigación y más información en profundidad.
  2. Seleccione “Topics” en la barra de herramientas superior para saltar directamente a una de las 11 páginas de temas. Cada página del tema incluye un resumen de las investigaciones relevantes, publicaciones de blog y enlaces relacionados.
  3. Utilice la ” “List View” para ver los datos de cada tema en un formato de lista.

También dispones de un tutorial de ayuda.

Como centros de aprendizaje en el siglo XXI, las bibliotecas deberían estar más implicadas en la ciencia del aprendizaje. Para apoyar mejor a los usuarios y diseñar programas eficaces de biblioteca, se necesitan mejores herramientas para entender cómo aprenden las personas mejor y cómo facilitar el aprendizaje. El Mapa de Investigación de Digital Proimise responde a esta necesidad conectándonos directamente con los resultados de la investigación sobre educación y aprendizaje. A través de dos visualizaciones interactivas de datos, se pueden explorar miles de artículos de más de 180 revistas científicas.

Abstract

Recent advances in environmental magnetism offer the opportunity to link the magnetic signature of marine and continental rocks to the paleoenvironmental and paleoclimatic settings that controlled their formation or deposition, as well as to post-depositional events, such as diagenesis, that can alter their primary signature. This Research Topic assembles studies that used state of the art rock magnetic techniques to unravel the causes and effects of catastrophic geological events, including tsunami, meteorite impacts, Archean oxygenation event, geomagnetic reversals, and global climate changes linked to large volcanic eruptions.

Es evidente el creciente número de niños que son diagnosticados con trastornos del neurodesarrollo, y está claro que este aumento no puede ser explicado sólo por antecedentes genéticos. Varios estudios, entre ellos estudios epidemiológicos, han encontrado una asociación entre la exposición in utero y en la infancia a ciertos productos químicos, tales como disruptores endocrinos, productos farmacéuticos psicoactivos, productos químicos orgánicos volátiles, compuestos orgánicos persistentes y metales pesados y el desarrollo del cerebro de los niños.

Sin embargo, los mecanismos por los cuales estas sustancias químicas afectan el desarrollo y la función del cerebro no se conocen completamente. Además, poco se sabe acerca de cómo estos productos químicos entran y se acumulan en el cerebro. Los enfoques experimentales son esenciales para entender cómo estos químicos nocivos entran en el cerebro de los niños y poseen efectos discretos en sitios específicos del cerebro.
