"A webinar can take many forms, such as a meeting, presentation, or workshop. The main difference between running a webinar and simply posting a video is the interactive component the former offers. Attendees typically view webinars in real time, and there is often the option for them to participate by asking and/or answering questions. This type of seminar offers an excellent opportunity to add a personal touch to your platform and engage your customers. For example, Neil Patel uses webinars frequently to reach out to visitors of his traffic growing website. Step #1: Create a Google Account Step #2: Create a New Event in YouTube Live Step #3: Customize Your Webinar Step #4: Embed Your Webinar in Your WordPress Website Step #5: Invite Attendees Step #6: Broadcast Your Webinar"

"the ultimate goal is not to have students blog, it is to have students improve their literacy skills and have the ability to be digital writers, and to do things that would not be possible without the technology.  It is about students creating content to hyperlink to the world, to embed photos and video with text.  It is about students publishing, and then to have the opportunity to receive feedback on their work, review, edit and republish. It is about students producing work not only for their teacher, but for the world. It is about students having their own space to be creative and connect in new ways.  It is, ultimately, about students having greater ownership of their learning."

"1. Blogging enables reflection. This is true for both students and educators. Too often do we go through our days, class to class, with minimal opportunities for reflection on our experiences or the information that we have acquired along the way. Blogging offers the opportunity to take a step back and connect with our learning and place it in the context of the bigger picture. Make reflection an assignment or part of another assignment - it is an important component to learning. For students: This is not the easiest thing to accomplish - blogging takes time and that is a finite resource during a busy class period. There is great opportunity in academic support periods or advisory classes for students (particularly in 1:1 schools) to blog. Many advisory classes take place throughout the day, which is a great break point for students to create based on their learning from that day. For teachers: This type of reflection can and should be compiled into your lesson planning for future lessons. Take what you learned from teaching and learning that day and incorporate it into the next day's lessons. Find time to do this during a conference period during your day or right after school. Yes, it is tough to get in the habit of doing a new thing - but once you start using reflection through blogging, I think that your lesson planning will be easier and much more meaningful. 2. Develop an Authentic Audience An authentic audience is a great way to increase rigor and in all of my experiences has led to increased performance by students. Authentic audiences in blogging could mean any number of things - family members, students from other classes, students from other buildings, other teachers, individuals interested in the content from around the world, etc. A student knowing that their work may be seen by people other than what they consider their 'typical audience' (read: teacher) typically spends more time and exerts more effort to creating a quality p

"La publicación de un informe PISA de la OCDE acerca de cómo repercute el uso escolar de los ordenadores en las notas de los alumnos desencadenó ayer una oleada de titulares absurdos, irresponsables, cogidos por los pelos y peligrosísimos de cara al futuro, en los que con toda ligereza se acusaba a la introducción de la tecnología de "no servir para nada", o incluso de poco menos que "ser perjudicial para el aprendizaje". Una lectura mínimamente rigurosa del estudio permite ver que en realidad, se trata de una interpretación absurda. Lo que el informe viene a demostrar es que en las circunstancias actuales, con una introducción de tecnología que se ha limitado a cambiar las herramientas sin variar la metodología, y que se aún encuentra en una fase de pruebas absolutamente temprana, los resultados no son milagrosos, sino simplemente lógicos: si quitamos a los alumnos el papel y el bolígrafo y les ponemos un tablet o un dispositivo similar en las manos… ¡sorpresa! ¡Se distraen más! Lo raro, por supuesto, sería que esto no ocurriese así. Resulta no evidente, sino de perogrullo, que un artefacto electrónico conectado a la red ofrece infinitas oportunidades más para la distracción que las que ofrece un papel y el bolígrafo en el que, como mucho, podemos dibujar unos cuantos muñecos con palotes, hacer algunas cadenetas, o ya acercándonos casi a los deportes de riesgo, hacer una pajarita. Frente a esto, la versatilidad de los terminales móviles o los ordenadores es impresionante: podemos comunicarnos, acceder a un ilimitado océano de contenidos buenos, malos o regulares, ver vídeos de gatitos, o incluso jugar. Obviamente, si lo único que hacemos es cambiar de soporte, pero no alterar la metodología, ni formar a los profesores, ni modificar siquiera la manera de evaluar, lo único que haremos con la tecnología es crear una generación de alumnos que se habrán pasado una parte significativa del tiempo de clase dedicándose a otras

"Burden of Poverty Lacking money or time can lead one to make poorer decisions, possibly because poverty imposes a cognitive load that saps attention and reduces effort. Mani et al. (p. 976; see the Perspective by Vohs) gathered evidence from shoppers in a New Jersey mall and from farmers in Tamil Nadu, India. They found that considering a projected financial decision, such as how to pay for a car repair, affects people's performance on unrelated spatial and reasoning tasks. Lower-income individuals performed poorly if the repairs were expensive but did fine if the cost was low, whereas higher-income individuals performed well in both conditions, as if the projected financial burden imposed no cognitive pressure. Similarly, the sugarcane farmers from Tamil Nadu performed these tasks better after harvest than before. Abstract The poor often behave in less capable ways, which can further perpetuate poverty. We hypothesize that poverty directly impedes cognitive function and present two studies that test this hypothesis. First, we experimentally induced thoughts about finances and found that this reduces cognitive performance among poor but not in well-off participants. Second, we examined the cognitive function of farmers over the planting cycle. We found that the same farmer shows diminished cognitive performance before harvest, when poor, as compared with after harvest, when rich. This cannot be explained by differences in time available, nutrition, or work effort. Nor can it be explained with stress: Although farmers do show more stress before harvest, that does not account for diminished cognitive performance. Instead, it appears that poverty itself reduces cognitive capacity. We suggest that this is because poverty-related concerns consume mental resources, leaving less for other tasks. These data provide a previously unexamined perspective and help explain a spectrum of behaviors among the poor. We discuss some implications for poverty policy."

"MapMap is a free, open source software for projection mapping aimed at artists and small teams. Its intuitive interface facilitates learning and promotes artistic expression. This software is available on Windows, OSX, and Linux. MapMap gives users the ability to projection map on any surface of choice. Mapmap takes media sources and gives users the ability to manipulate the media into different positions and shapes. Media sources can come from any various accepted media formats. With an easy to understand interface, new users can get started in minutes. Projection mapping, also known as video mapping and spatial augmented reality, is a projection technology used to turn objects, often irregularly shaped, into a display surface for video projection. These objects may be complex industrial landscapes, such as buildings. By using specialized software, a two or three dimensional object is spatially mapped on the virtual program which mimics the real environment it is to be projected on. The software can interact with a projector to fit any desired image onto the surface of that object. This technique is used by artists and advertisers alike who can add extra dimensions, optical illusions, and notions of movement onto previously static objects. The video is commonly combined with, or triggered by, audio to create an audio-visual narrative."

""Hace 14 años me borré de Facebook. El mismo día que compró WhatsApp, lo desinstalé. Tampoco tengo Instagram. Eso te da una idea de lo que pienso de Zuckerberg". Es la tarjeta de presentación que suelta Paloma Llaneza entre risas al poco de arrancar. Esta abogada, auditora de sistemas y consultora en ciberseguridad, es una de las voces más respetadas en nuestro país en el terreno de la privacidad 'online'. O, más bien, en la ausencia de ella. Cree que los GAFA (Google, Apple, Facebook y Amazon) nos han colado un imperdonable gol, pero la culpa no es (del todo) nuestra. "Nos han vuelto adictos a sus servicios gratuitos, nadie les ha parado los pies y ahora es muy difícil volver atrás". Pero al menos queda un último recurso: soltar lastre, dice, destruir cualquier rastro de esas siglas en tu móvil. "Yo lo he hecho y, oye, ¡no me he muerto!". Llaneza, con más de dos décadas de experiencia y casi una decena de libros a sus espaldas, publica ahora un nuevo ensayo, 'Datanomics' (Deusto, Grupo Planeta), una obra divulgativa en la que achicharra página tras página a los gigantes de Silicon Valley y explica a la perfección cómo hemos llegado a esta especie de salvaje oeste de internet. "Hubo un cambio de paradigma al ganar Trump las elecciones. Eso generó tal convulsión en EEUU que se empezaron a buscar culpables". Y ahí estaba Facebook y su cloaca de datos. Y Google, y WhatsApp, las 'fake news', Bolsonaro, Vox, la publicidad invasiva, el 'spam' electoral... El cóctel de lo que se está haciendo ahí fuera con tus datos (con y sin tu permiso), argumenta Llaneza, es tan preocupante que toca hacer algo. Ya."

"The transition from unicellular to multicellular life was one of a few major events in the history of life that created new opportunities for more complex biological systems to evolve. Predation is hypothesized as one selective pressure that may have driven the evolution of multicellularity. Here we show that de novo origins of simple multicellularity can evolve in response to predation. We subjected outcrossed populations of the unicellular green alga Chlamydomonas reinhardtii to selection by the filter-feeding predator Paramecium tetraurelia. Two of five experimental populations evolved multicellular structures not observed in unselected control populations within ~750 asexual generations. Considerable variation exists in the evolved multicellular life cycles, with both cell number and propagule size varying among isolates. Survival assays show that evolved multicellular traits provide effective protection against predation. These results support the hypothesis that selection imposed by predators may have played a role in some origins of multicellularity."

"Older children play too explores the play of older children, particularly those in early and middle adolescence (around the ages of 11 to 16). This information sheet looks at: Avoiding assumptions based on age alone Understanding the adolescent brain Play behaviours of older children and their benefits Where older children play and why Barriers to play and the social consequences Providing for play."

"To revert the current ecological overshoot and build a sustainable society, we have to collectively engage in changing our economic model. "Sufficiency: moving beyond the gospel of eco-efficiency" suggests introducing hard limitations to unsustainable trends-in particular to overconsumption-and putting emphasis on distributional justice. Seven chapters written by sustainability and economics experts plus a foreword by Janez Potočnik (Co-chair of the International Resource Panel and former European Commissioner for the Environment) shed light on different angles of sufficiency and formulate concrete recommendations to EU policy makers. The booklet ends with a discussion of several eco-social policies that can start the transition towards an "economics of enough". Many new ideas for an economic paradigm shift have been developed and discussed at the academic and grassroots levels in recent years. The aim of this booklet is to build on a rich body of knowledge and bring these ideas to the attention of engaged citizens and policy makers in order to advance the debate on how to implement sufficiency."

"The cryptocurrency uses as much CO2 a year as 1m transatlantic flights. We need to take it seriously as a climate threat Bitcoin's electricity usage is enormous. In November, the power consumed by the entire bitcoin network was estimated to be higher than that of the Republic of Ireland. Since then, its demands have only grown. It's now on pace to use just over 42TWh of electricity in a year, placing it ahead of New Zealand and Hungary and just behind Peru, according to estimates from Digiconomist. That's commensurate with CO2 emissions of 20 megatonnes - or roughly 1m transatlantic flights."

"This book YOUNG & CREATIVE - Digital Technologies Empowering Children in Everyday Life aims to catch different examples where children and youth have been active and creative by their own initiative, driven by intrinsic motivation, personal interests and peer relations. We want to show the opportunities of digital technologies for creative processes of children and young people. The access to digital technology and its growing convergence has allowed young people to experiment active roles as cultural producers. Participation becomes a keyword when "consumers take media into their own hands". Digital technologies offer the potential of different forms of participatory media culture, and finally creative practices. YOUNG and CREATIVE is a mix of research articles, interviews and case studies. The target audience of this book is students, professionals and researchers working in the field of education, communication, children and youth studies, new literacy studies and media and information literacy."

""Este es el mapa sobre el cambio climático para los que no creen en el cambio climático". Así definía Parag Khanna, investigador de la globalización de la Kuan Yew School, el controvertido mapa que muestra cómo sería un mundo con 4ºC más. Es triste, pero en el ambiente flota la idea que mostrar los resultados demasiado catastróficos no logra convencer a los negacionistas. Pero este mapa tiene algo positivo y noveodso: a parte de las zonas afectadas por la tragedia muestra también posibles soluciones para habitar el nuevo planeta recalentado. Estas eran algunas de las conclusiones que indicaba el mapa: -México, Perú, Ecuador y Brasil se han convertido en desiertos. -Antártico oeste, Siberia, Canadá, Reino Unido, Escandinavia, Groenlandia, el norte de Rusia y Nueva Zelanda serán los países que acogerán a los refugiados del cambio climático y donde se podrá cultivar alimentos. -En el Ártico todo será verdor después que el hielo se haya fundido. Será una ruta comercial navegable durante todo el año que unirá Canadá y Rusia. -Sur de Europa: España, la mitad sur de Francia, Italia, Grecia, Bulgaria y otras ciudades del sur de Europa se han convertido en un desierto sólo apto para el cultivo de energía solar y geotérmica. Ciudades como Barcelona, Venecia y Estambul han quedado inundadas. ¿Qué había de cierto en este mapa publicado en 2009 en New Scientist? Según los estudios más recientes ese mapa era demasiado optimista. Porque solamente 0.5ºC de temperatura tendrían un impacto fatal sobre el planeta. Y porque no, el cambio climático no es algo negociable. "

"There is only a 5% chance that the Earth will avoid warming by at least 2C come the end of the century, according to new research that paints a sobering picture of the international effort to stem dangerous climate change."

"In order to help reduce the gap between industrialized countries and those in the emerging economy, UNESCO has decided to adopt an Open Access Policy for its publications by making use of a new dimension of knowledge sharing - Open Access.
