32 Year Satellite images Time-lapse Shows the Immense Change of Tripoli, Lebanon

It is no a secret that the past 50 years have seen a tremendous leap and bounds in technologies and (mega) construction. Although everyone is excited about it, this also raises the question, whereto? The idea that out of the thousand years humans have been in this world, only the past half a century has seen an unparalleled spring in materialism (humanism has deplorably spiraled down, perhaps this shows a reversed correlation?). Using Google Earth Engine Timelapse, I have captured how my hometown, Tripoli, Lebanon, has transformed (amorphously) in the past 32 years (1984 – 2016). Timelapse is a global, zoomable video that lets you see how the Earth has changed over the past 32 years. It is made from 33 cloud-free annual mosaics, one for each year from 1984 to 2016. Using Earth Engine, we combined over 5 million satellite images acquired over the past three decades by 5 different satellites. The majority of the images come from Landsat, a joint USGS/NASA Earth observation program that has observed the Earth since the 1970s. Here’s the video





Based on screenshot images, you can notice how a massive shift in construction, and destruction of green areas, has taken place at key years, specifically between 2010 and 2016. If 32 years have done that damage to our world, and have drastically increased urban density, imagine the world in the next 30 years. Would you wish your children to live in such a place?

198 METHODS of Nonviolent Actions to Instill Change

In 1972, Gene Sharp produced  a brochure listing 198 methods on nonviolent actions to instill change. Since then, his methods have become a blueprint for nonviolent actions around the world. I publishing it here in the hope that this might spark done ideas for change. Practitioners of nonviolent struggle have an entire arsenal of “nonviolent weapons” at their disposal. Listed below are 198 of them, classified into three broad categories: nonviolent protest and persuasion, noncooperation (social, economic, and political), and nonviolent intervention. A description and historical examples of each can be found in volume two of The Politics of Nonviolent Action, by Gene Sharp. THE METHODS OF NONVIOLENT PROTEST AND PERSUASION Formal Statements                     1. Public Speeches                     2. Letters of opposition or support                     3. Declarations by organizations and institutions                     4. Signed public statements                     5. Declara

Capturing Solutions for Organizational Learning and Scaling Up

The World Bank has published a much needed guidebook for organizations on how to document operational experiences for organizational learning and knowledge sharing . It also discusses the significance of organizational capabilities at two levels: Enabling Environment for Knowledge Sharing and Technical Skills. The  publication asks a simple, yet important, question: Is your organization missing important lessons from its operational experiences? This step-by-step guide shows you how to systematically capture such knowledge and use it to inform decision making, support professional learning, and scale up successes. The captured lessons--knowledge assets, the central element needed for learning--are consistently formatted documents that use operational experience to answer a specific question or challenge. The guide describes how to create and use knowledge assets in five steps: (1) identify important lessons learned by participants, (2) capture those lessons with text or multimedia do

Hattie’s Effect Size: A pseudoscience or critics just being critics?

Hattie’s meta-mata analysis that culminated in the publication of his most influential work of Visible Learning (2009), and later updated to include more studies, has been hailed as the “holy grail” for educators and education leaders around the world. In particular, his effect size of instructional practice interventions has had the lion’s share of his work. Hattie considered that if schools set the effect size at 0 then “virtually everything works, and so we need to shift the question from “ what works in education” to “what works best in education”. Hattie’s meta-meta analysis of more than 800  meta-analyses studies comprising 50,000 studies (later included more 1500 meta-analyses) revealed that the baseline of the effect size that schools should start from is not 0 but 0.4, termed as the “hinge point”. In other words, for medium to large effect sizes on student achievement, the effect size of an instructional practice should be o.4 and above. This does not mean that we need
