Muy interesante herramienta para pasar tablas de datos a visualizaciones gráficas, en vectores y personalizables... "RAW works with tabular data (i.e. information which is possible to record or track in a spreadsheet). There are many ways you can upload your data in RAW: Dropping a plain text file containing delimiter-separated values such as .csv or .tsv. File extension does not matter, as long as you use one of these delimters: comma, semicolon, tab or colon. Copying and pasting your data from a spreadsheet (e.g. Microsoft Excel, Google Docs, Apple Numbers...) or a text file. This is particularly helpful when you do not want to (or can not) export your data any time you change it or when you want to use only specific columns. Typing your data directly into the text area. While it is unlikely to use this option, it can be useful for editing your data."

"... El camino a la inteligencia artificial está lleno de sesgos. Y, justamente, es en este punto donde aparecen los problemas. Hace unos años atrás, la gran "buzzword" era el "big data". Donde uno fuera, el big data era lo principal: big data esto, big data aquello. Tras todo el humo que fue dejando el big data, empezó a emerger de manera más clara que uno de los usos fundamentales de la recolección masiva de datos no era solamente venderte champú o tests de embarazos, sino también entrenar a las redes de inteligencia artificial. En efecto, cuanto más grande y correctamente organizado sea el conjunto de datos que un sistema de inteligencia artificial tiene para entrenarse, tantas más posibilidades tiene de mejorar el sistema sus capacidades. O eso pensábamos. Pronto, distintas aplicaciones que hacen uso de inteligencia artificial empezaron a mostrar sus fallas. Así, Google confundió las caras de las personas negras con gorilas; Nikon le insistió a una asiática para que manteniera los ojos abiertos, pero también los resultados de búsqueda le devolvieron a las mujeres trabajos por salarios menores a los que les ofrecían a los hombres, y así sucesivamente. ..."

"Max Roser (2016) - 'World Poverty'. Published online at OurWorldInData.org. Retrieved from: http://ourworldindata.org/data/growth-and-distribution-of-prosperity/world-poverty/ In the past only a small elite lived a life without poverty. Since the onset of industrialization - and as a consequence of this, economic growth1 - the share of people living in poverty started decreasing and has kept on falling ever since. But as a consequence of falling poverty, the health of the population improved dramatically over the last two centuries, and the population started to grow.2 The growth of the population caused the absolute number of poor people in the world to increase; only recently has the absolute number of people living in poverty started to fall as well.

"El Turco es un lenguaje neutral en materia de género. No hay " Él " o " ella " - todo es " o ", y sólo puedes decir de qué sexo se trata desde el contexto. Cuando traduces frases turcas en inglés con google translate, algo destacable sucede: las frases se clasifican por género. Por qué? Google translate usa un algoritmo que basa sus traducciones en la frecuencia de uso observada. Así que si en la base de datos hay 1,000 usos de la palabra "Ingeniero" y la mayoría de ellos son hombres, traduce al ingeniero como si unicamente los hombres lo pudieran ser. Lo mismo va para "enfermera", para mujeres. La tecnología está lejos de ser neutral. La forma en que estamos utilizando la tecnología está reforzando actualmente las desigualdades y los prejuicios del mundo que nos rodea. La tecnología está haciendo que estos sesgos sean más sólidos y más rígidos como los algoritmos que vienen a determinar cada vez más partes de nuestras vidas. Nos estamos rindiendo a la tecnología porque se nos ha prometido que ofrece una forma de salir de nuestros dilemas actuales. Pero no lo olvides: la tecnología es moldeada por sus creadores. Y la industria de alta tecnología es una gran industria blanca, rica y joven, definida por el sexismo rampante, el racismo, el clasismo y muchas otras formas de desigualdad social. Y estos son los resultados."

"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."

"Enrique Javier Díez Gutiérrez | la OCDE que busca utilizar PISA para llevar las políticas educativas en una dirección determinada. nuevatribuna.es 23 de Junio de 2015 (16:30 h.) PISA carece completamente de valor como guía para mejorar la enseñanza a nivel de escuelas y de países Julio Carabaña, uno de los sociólogos de la educación más reputado, ha publicado recientemente la investigación "La inutilidad de PISA para las escuelas", donde demuestra sólidamente que este programa de evaluación internacional carece de valor para ayudar a mejorar la enseñanza en las aulas y el funcionamiento de las escuelas. "PISA carece completamente de valor como guía para mejorar la enseñanza a nivel de escuelas y de países, y por tanto de utilidad para los docentes y para los políticos". Así de contundente se muestra Carabaña, ante la constatación de que las pruebas de este examen miden capacidades muy generales. Capacidades que dependen de la experiencia acumulada en toda la vida del alumnado, desde su nacimiento. Por lo que, como incluso reconoce PISA en sus propias textos "si un país puntúa más que otro no se puede inferir que sus escuelas sean más efectivas, pues el aprendizaje comienza antes de la escuela y tiene lugar en una diversidad de contextos institucionales y extraescolares". De ahí la inadmisible pretensión de la OCDE que busca utilizar PISA para "llevar las políticas educativas en una dirección determinada". No sólo porque las capacidades que mide PISA dependen poco o nada de las escuelas, sino porque ni siquiera dependen de los cambios pedagógicos y políticos que PISA propone. "Este fallo fatal inutiliza completamente a PISA para su objetivo principal, ayudar a la mejora de las escuelas y los sistemas educativos", afirma este especialista. "No se trata de un fallo secundario o accidental, sino de un fallo esencia, fatal, que convierte PISA primero en un fracaso y, con el tiempo, en un fraude". Entonces

This paper reports on the outcomes of a mini-research project about visible forms of collaboration when children are learning with the support of Wikis-online editable websites. The findings were based on observing the children using the Wiki, analysis of the video recording of the task and the survey that was completed by the children using the Wiki as a tool for a task. Qualitative research methodology became a primary technique for the data collection and content analysis approach used to explore the children's behaviour when investigating the use of the wiki and video recording of the sessions. Various types of behaviour associated with collaboration, were observed when the children were working on Wiki pages with their peers.

"Our new blog is designed to radically reduce the energy use associated with accessing our content. Low-tech Magazine was born in 2007 and has seen minimal changes ever since. Because a website redesign was long overdue - and because we try to practice what we preach - we decided to build a low-tech, self-hosted, and solar-powered version of Low-tech Magazine. The new blog is designed to radically reduce the energy use associated with accessing our content. Why a Low-tech Website? We were told that the Internet would "dematerialise" society and decrease energy use. Contrary to this projection, it has become a large and rapidly growing consumer of energy itself. In order to offset the negative consequences associated with high energy consumption, renewable energy has been proposed as a means to lower emissions from powering data centers. For example, Greenpeace's yearly ClickClean report ranks major Internet companies based on their use of renewable power sources."

"Exclusive: Insects could vanish within a century at current rate of decline, says global review The world's insects are hurtling down the path to extinction, threatening a "catastrophic collapse of nature's ecosystems", according to the first global scientific review. More than 40% of insect species are declining and a third are endangered, the analysis found. The rate of extinction is eight times faster than that of mammals, birds and reptiles. The total mass of insects is falling by a precipitous 2.5% a year, according to the best data available, suggesting they could vanish within a century."

"Select a country to view its environmental sustainability and social performance relative to the "safe and just space" framework and see how it compares with other countries. Blue wedges show social performance relative to a threshold associated with meeting basic needs (blue circle), green wedges show resource use relative to a biophysical boundary associated with sustainability (green circle), while grey wedges show indicators with missing data. Wedges with a dashed edge extend beyond the chart area. Ideally a country would have blue wedges that reach the social threshold and green wedges within the biophysical boundary. See the tables below for country-specific details."

"The Chinese government blocked 17.5 million would-be plane passengers from buying tickets last year as a punishment for offences including the failure to pay fines, it emerged. Some 5.5 million people were also barred from travelling by train under a controversial "social credit" system which the ruling Communist Party claims will improve public behaviour. The penalties are part of efforts by president Xi Jinping's government to use data-processing and other technology to tighten control on society."

"El secreto está en 18 dibujos y el número de imágenes por segundo o frecuencia a la que captura la cámara. Se llama ciclótropo y es un proyecto de Tim Wheatley, un estudiante del University College Falmouth. Parece inspirado por la clásica idea del zoótropo o máquina estrobosópica, que data de principios del siglo XIX. En este caso se emplea una rueda de bicicleta con cartones en los que hay dibujos y piezas salientes que adoptando diversas «formas animadas» producen un efecto sin duda curioso."
