The Elders are shocked and deeply saddened at the passing of their dear friend and colleague Kofi Annan, who was the globally admired and respected Chair of The Elders.A founding member of The Elders, Kofi Annan succeeded Archbishop Desmond Tutu as Chair in May 2013. He played a vital role in leading The Elders’ work, and was a voice of great authority and wisdom in public and private, most recently on visits to South Africa and Zimbabwe in July 2018.As the seventh Secretary-General of the United Nations from 1997 to 2006, he was a constant advocate for human rights, development and the rule of law. The first Secretary-General to reach the post from within an organisation he served for over 40 years, Kofi Annan had a life-long commitment to the cause of peace and was known for his staunch opposition to military aggression, notably the US-led invasion of Iraq in 2003.The great respect for him and his essential work was illustrated when he, together with the United Nations as a whole, was awarded the Nobel Peace Prize in 2001.Gro Harlem Brundtland, Deputy Chair of The Elders, said:“We are devastated at the loss of our dear friend and fellow Elder. Kofi was a strong and inspiring presence to us all, and The Elders would not be where it is today without his leadership. Throughout his life, Kofi worked unceasingly to improve the lives of millions of people around the world. While we mourn his passing today, we resolve as Elders to continue to uphold his values and legacy into the future”.In retirement, Kofi Annan continued where he had left off at the United Nations, founding and leading the work of the Kofi Annan Foundation, based in Geneva, and maintaining a hectic international schedule. His quiet advice on how best to defuse impending crises was in constant demand from all corners of the globe, in particular from Africa.All of the Elders and their Advisory Council and staff team members send their heartfelt condolences to Kofi’s family: his wife Nane, his children and grandchildren. They have lost a devoted husband, father and grandfather.The world has lost an inspiring figure – but one whose achievements will never be forgotten, and whose commitment to peace and justice will endure to inspire future generations.Leaders, charities and stars around the world have also expressed their sadness at the passing of Kofi Annan.“I was saddened and heartbroken to learn of the passing of Kofi Annan. Father. Husband. Humanitarian. Elder. He was a lifelong servant of peace,” said UNICEF Executive Director Henrietta Fore. “He was particularly concerned about the future – the world our children and their children will inherit. And he led the United Nations during a time when millions emerged out of poverty and he helped shape the future of global development work.“Most of all, Kofi Annan believed in the project of the United Nations. When once asked why he had failed to advance reforms, he reportedly quipped, ‘the Lord had the wonderful advantage of being able to work alone.’ Yet, through his six decades of international public service, Annan was committed to making sure he was not alone – enlisting us all in the work of building a better world.“And in the end, Annan’s life reflected his understanding of it – that the fate of each of us determines the fate of all of us. On behalf of everyone at UNICEF, I extend my deepest condolences to his family, his beloved nation of Ghana, and the UN community.”“I’m deeply saddened by the passing of Kofi Annan, a true global statesman and man of integrity,” added UNHCR Special Envoy Angelina Jolie. “Like many others, I will remember him for his kindness, his grace, and his calm strength of purpose. My thoughts are with his wife and family.”“Like so many, I was proud to call Kofi Annan a good friend and mentor. I was deeply honoured by his trust in selecting me to serve as UN High Commissioner for Refugees under his leadership. He remained someone I could always turn to for counsel and wisdom — and I know I was not alone,” UN Secretary-General António Guterres said in a statement. “He provided people everywhere with a space for dialogue, a place for problem-solving and a path to a better world. In these turbulent and trying times, he never stopped working to give life to the values of the United Nations Charter. His legacy will remain a true inspiration for all us.”The UN Foundation Board today released the following statement in response to news of the death of former UN Secretary-General Kofi Annan, a UN Foundation Board Member since 2007.“We are devastated by the loss of Kofi Annan – our fellow Board member, former Secretary-General, and friend. Kofi was a towering figure whose deep humanity, compassion, and courage inspired everyone whose life he touched. We are privileged to have worked with such an honorable man and visionary leader. His achievements will not be forgotten, nor will his impact on history.“Kofi led the United Nations into the modern era and shaped the best of what it stands for today. He insisted on holding the UN to the highest standards and was relentless when it fell short. We pay tribute to his tireless efforts to fight for peace, justice and human dignity. He believed that anyone could take a stand, make a difference, and help create a better world for all – especially women and young people – and he always took time and effort to listen to those who too often went unheard. In his own story, he showed us all how a life well-lived could be a powerful force for good. There was not a part of the world he left untouched.“His loss on the eve of World Humanitarian Day, when we remember the service and sacrifice of humanitarians and peacemakers around the world, reminds us only further of his life and leadership. We send our heartfelt condolences to his wife Nane, children and grandchildren and all those who knew and served alongside him. He will be forever remembered.”Ted Turner, UN Foundation Founder and Chairman, said: “Kofi Annan was a friend and a champion for peace. He opened the doors of the UN to me and millions of others who have been inspired by the UN’s values. He challenged us to help make a difference for the world, and he led with a formidable combination of compassion, fierceness and hope. We will miss him greatly.”During his tenure as Secretary-General, Kofi Annan led one of the most comprehensive efforts to revitalize the United Nations and make the international system more effective. He strengthened UN peacekeeping, adopted the UN’s first-ever counter-terrorism strategy, and led Member States to adopt the “responsibility to protect” framework that addressed genocide, war crimes, ethnic cleansing, and crimes against humanity. In addition, he helped establish the Global Fund to fight Tuberculosis, AIDS and Malaria, and launched the Global Compact initiative that continues to encourage corporate social responsibility.In 2001, the UN and Kofi Annan were jointly awarded the Nobel Peace Prize. The Nobel Committee commended Annan for “bringing new life to the organization,” balancing the UN’s traditional role in peace and security with greater emphasis on human rights across the world.Bill Clinton had this to say: “Kofi Annan was a truly great UN Secretary-General. It was an honor to work with him in his efforts to reform the UN, strengthen global health and peacekeeping, and reduce poverty. He made the fight against AIDS and the responsibility to protect civilians in conflict zones true priorities for the UN.“After he left office, he continued his leadership on poverty, environmental, and peace issues through his foundation. In every phase of his life, he held fast to his Ghanaian roots and set a powerful example of determined leadership while always treating others with respect and dignity.“I will always be grateful to have worked with him as President and later as UN Special Envoy for Tsunami Recovery. Hillary and I treasured our friendship with him and Nane, and our thoughts and prayers are with her and their family.”

I love Google. I believe it to be one of the greatest American businesses ever launched. For the last dozen years, I have been a partner as well as competitor to Google. I have seen firsthand the incredible breadth of engineering talent and resources they bring to the market. As a publisher, I was a long-time customer of syndicated Google search advertising as well as embedded, contextual text advertising.Google is brilliant at serving and monetizing text advertising. Whether done on the search result page or via contextual mapping to page level content into a dedicated module, these are solutions that no publisher can directly offer. These are solutions based on mapping scale of advertisers to scale of potential keywords, something no individual publisher can possibly replicate. The money generated from these placements is incremental and does not compete with the publishers’ own direct efforts to sell a similar product.Display is a different ballgame. A premium publisher’s core business is in selling a high-value display placement into their curated environment at a premium price. While programmatic buying is surely challenging the value of this model, it still represents a significant market with hundreds of top-tier brand marketers placing value on the age-old premise of the right ad delivered to the right individual in the right environment. Google’s core display product undercuts this model in damaging ways. Google will serve what its algorithm perceives to be the best possible ad at that given moment. It does not discern the appropriateness of the ad content itself or the economics involved. This often defaults to the lowest common denominator served into a premium display position—a text ad, from a direct response marketer, sold for less than 10 percent of what the publishers’ direct sales force is trying (and succeeding ) to get for that same inventory.This is particularly damaging in emerging areas like mobile. Because most premium publishers don’t sell their mobile inventory yet, you often see Google text ads appearing in prime display mobile real estate. Because many of these publishers are using DFP as their first party ad server, Google wisely makes it very easy for them to automate their Adsense backfill.Here is the prime example. This is a screen shot of The New York Times mobile home page from a few months back. The NYT has not sold this position so it defaults to a backfill solution from Google. This is what served: Now I’m an old digital guy and still view the home page of the NYT as a very premium buy. I see top 50 brands paying top dollar to get that position. Google has done a great service to the Counseling Anxiety in Miami advertiser. I wonder if they even know they owned the homepage of the NYT. For the NYT, this is a horrible result. Never mind the poor quality of the ad content and how that sullies the environment for the reader; I’m not sure how their sales team can go to market selling the exclusivity of the placement to their top-brand advertising partners when this is what’s running there.So what can you do if you’re a premium publisher with lots of unsold inventory?1. Put the right resources in place to sell it yourself, and in the way it needs to be sold—as a high-value, high-impact display unit.2. Work with specialist networks that focus on premium inventory and premium brands.3. If you’re going to backfill, do it via an SSP (Pubmatic, Rubicon, or even AdMeld, which Google owns), where more competition for the inventory should produce better ads and better economics.4. If you’re going to just run Google ads, then have somebody at the switch watching to make sure there are minimum standards of ad content quality and yield.Don’t get me wrong; Google is a great and critical partner to the publisher and would be the first to point out they give the publisher control to manage their inventory. The reality is that most publishers don’t have the resources to do this, so they default to something that in the long run undermines their business. Be smart. Protect the premium value of your brand and inventory.
In the large image, particles in a pile of graphite powder erupt due to illumination with a red laser. The laser heats particles just below the surface the most, causing surface particles to jump up due to photophoresis and the solid state greenhouse effect. The inset is an eruption of vitreous carbon. The images are long exposures, and the laser was slowly moved to excite different locations. Photo credit: Gerhard Wurm and Oliver Krauss. Citation: Scientists pin down causes of dust eruptions (2006, April 18) retrieved 18 August 2019 from https://phys.org/news/2006-04-scientists-pin-eruptions.html When the physicists turned the laser off, they observed an intriguing effect. The point where the temperature gradient changes (the highest temperature) moves deeper into the dust bed. In the tenths of seconds after the laser is turned off, the photophoretic force increases further below the surface, causing larger aggregates to be ejected from the upper part of the bed.“When you turn off the laser, the normal cooling begins,” explained Wurm. “And since the temperature gradient at the surface is largest in absolute terms, heat flows in this direction better, which is why the maximum has to shift further into the sample.”Because photophoresis works best in low-pressure environments (10 mbar used in this experiment), it would be rare to observe the force naturally acting on dust particles near the surface of the Earth. However, in the early days of Earth – as well as other planets and stars – photophoretic ejection at sub-mbar pressures likely played a role in the growth of gas-dust disks, which in turn triggered the formation of asteroids and Kuiper belt objects.For future applications, the physicists theorize that Mars’ low surface pressure make the planet a candidate to host the photophoretic force. For example, with the equipment used on Mars exploration missions, photophoretic technology could aid in the removal of dust from solar panels and lenses. Further, the scientists consider creating a solar sail that would be powered by the photophoretic force instead of radiation pressure.“You could construct a fabric which would look, for example, like a fisher-net with micron or sub-micron-sized fibers,” explained Wurm. “The individual fibers would have ‘negative photophoresis,’ which occurs when particles are pulled by the light after being ejected, and the whole net should be lifted by light. With negative photophoresis, I’d guess a sail might carry a few times its own weight just by ‘passive’ sunlight. . . Say a 10 meter by 10 meter sail might carry a few tens of kilograms.”Wurm and Krauss also speculate on the possibility of fabricating an artificial surface that would optimize photophoretic forces on Earth, as well as industrial applications. Because all these possibilities are based on studies of “dirt,” these experiments take advantage of something often considered an everyday nuisance.“With modern physics, it is hard to come by the effects we observed here because everyone is proud of working in a clean environment at ‘perfect’ vacuum,” said Wurm. “This is fantastic, but you never see photophoretic effects there. You need the gas, the ‘bad’ vacuum, and you need the dirty surfaces.“With respect to planet formation, dust really holds the clues to our origins. The word ‘dust’ implies rather negative feelings because it is related to dirt in everyday life. Dust is everywhere. We will never love it and we can’t leave it. You could call it micro- or even nanoscience and it might sound a little better and fancier for research – but we’re still talking about dust, whatever name tag you put on it.”Citation: Wurm, Gerhard and Krauss, Oliver. Dust Eruptions by Photophoresis and Solid State Greenhouse Effects. Physical Review Letters 96, 134301 (2006).By Lisa Zyga, Copyright 2006 PhysOrg.com By simple light and heat mechanisms, dust particles seem to defy gravity and leap up into the air. The effect, which once played a role in the formation of the Earth and asteroids, could also have applications in dust removal and even propel small probes on Mars. When shining a red laser beam on a pile of dust, some dust particles will jump up, apparently erupting in a fountain of dust strands (see image). In studying the mechanisms behind the erupting dust, scientists Gerhard Wurm and Oliver Krauss from the University of Munster found two causes working together that explain their observations: photophoresis and the solid state greenhouse effect.Photophoresis – or the movement of particles due to light – is based on a long-known effect called thermophoresis – or the movement of particles due to heat transfer. Essentially, in environments with temperature gradients, particles will migrate from hotter to cooler regions due to the thermophoretic force. When light absorption serves as the heat source, the mechanism is called the photophoretic force.In addition to the presence of a temperature-gradient surface, Wurm and Krauss found that the solid state greenhouse effect also plays a role in dust eruptions. This greenhouse effect occurs because the laser beam heats up dust particles slightly below the surface (at least 100 micrometers, which encompasses several tens of particle layers) the most. In a recent Physical Review Letters, the scientists describe how coupling photophoresis with this greenhouse effect means that surface dust particles will strive to migrate away from hot underlying particles – and that direction is up. The team found that the pull-off force for a spherical micron-size particle is around 10-7 N. On average, about a million particles are needed to overcome cohesion.“We observed particles jump up to 5 cm,” Wurm told PhysOrg.com. “You should get them to 10 cm but this might not be the limit. The limit probably depends strongly on the dust powder, its size distribution, cohesion and the light source.”With 50 mW laser power, radiation can penetrate a dust bed to a depth up to a few millimeters. While the temperature generally decreases deeper into the dust bed, the temperature actually peaks not at the surface, but around a depth of 100 micrometers. This reversed temperature gradient near the surface causes aggregates of dust grains to be ejected. Explore further This document is subject to copyright.
