Briefly, about Hans Rosling and his talk:

Even the most worldly and well-traveled among us will have their perspectives shifted by Hans Rosling. A professor of global health at Sweden’s Karolinska Institute, his current work focuses on dispelling common myths about the so-called developing world, which (he points out) is no longer worlds away from the west. In fact, most of the third world is on the same trajectory toward health and prosperity, and many countries are moving twice as fast as the west did.

Found the software on the video to be quite fascinating, and looked into his website, Gapminder.org

Here is where the magic lies: a fact-based world view, powered by statistics. This is an inkling of an idea I had a while ago, somewhat akin to data-driven decision-making. His graphs and animations are easy to follow, aesthetically pleasing, and they contain all the important information you need to understand the significance of the trend.

Parliamo ora di cose serie. Uno dei principali ostacoli fra la persona comune e la statistica sono i numeri. Il 70% della popolazione italiana è affetta da deficit di numeracy (italianamente detta “capacità di fare di conto” o “alfabetizzazione numerica”), il che comporta non solo una diffusa difficoltà a ragionare in termini matematici, ma anche l’incapacità di comprendere informazioni numeriche (percentuali, tassi, ..) e di leggere grafici e tabelle. Tutto ciò rende l’uomo comune vulnerabile alla strumentalizzazione che giornalisti, politici e comunicatori fanno dei dati statistici ufficiali. Insomma, molti sanno tenere i conti di casa ma ben pochi sono in grado di interpretare gli andamenti dell’inflazione (anche se spesso per colpa di giornalsti che, consapevoli o meno, usano le cifre per inventarsi fenomenali avvenimenti economici o sociali). Bien, per ora non ho detto nulla di nuovo. Allora passiamo direttamente al tema dell’articolo. L’OECD (per chi non lo sapesse è l’Organizzazione per la CoOperazione Economica e lo Sviluppo, OCSE da noi; ha sede a Parigi, membri sono circa una trentina di Paesi dall’Europa, agli USA al Giappone, un budget da 320 milioni di euro, nonchè uno dei principali produttori e fornitori di statistiche internazionali) si è occupata e continua ad occuparsi del problema della numeracy, arrivando a pensare che per comprendere la statistica (e perchè no, per far fare statistica) i numeri nn servano. La supposizione si è rivelata essere esatta. Pochi anni fa è stato sviluppato da un demografo e da un programmatore di videogiochi un programmino che permette “raffinate” comparazioni sociologico-demografiche nonchè economiche di portata mondiale. Questa meraviglia è stata battezzata Gapminder: vi assicuro che divertirvi con i dati OECD è un gioco da ragazzi, dato che questo software è stato messo nelle mani di ragazzini delle scuole medie che hanno prodotto piccoli rapporti da sociologi in erba. Se vi va di giocare un po’… buon divertimento!

Hans Rosling 是我在瑞典就有所耳闻的人物，不过开始认识还是从他在TED的talk. Gapminder巧妙利用了Google Motion Chart, 一个在Google doc中就可以使用的绘图Widget， 通过时间线来展示统计数据。这种极富创意的方式有效的凸显出了许多平时不被注意或是错误认定的差异（Gap），这也就是GapMinder的起源，意为Mind Your Gap。国与国，文化与文化之前的差异很多时候并不像我们主观所判断的相一致。需要有心人去重新解读这些已有的数据。GapMinder则是这其中的有力代表。

我刚刚给Gapminder发了一个询问的邮件，看看是不是有机会将我统计专业的毕业设计和他们有所相关，目前还在殷切的等待回复

在这个嵌入的视频中，Hans Rosling 回顾了中国对比英国的过去200年的发展轨迹，纵览了两国此间的兴衰，并预计了未来的发展的主线。 Video description:

200 years ago, United Kingdom was a leading nation of the world – both in regard to health and economy. In this video, Hans Rosling details UK’s 200-year journey, to present time, and also shows that China, in the coming five years, will catch up with UK faster than ever.

Check out GapMinder, the chart that shows changes in data with animation and you can use it on your web pages free!

It looks cool and its educational.

Efter 2 veckors social isolering pga tentaperiod är jag äntligen tillbaka till verkligheten igen. Tentornas taskiga timing innebar att jag tyvärr missade de två första dagarna av European Development Days (EDD), vilket jag försökte ta igen på mässans sista dag igår.

EDD är ett årligt event som arrangeras av Europeiska kommissionen tillsammans med det land som innehar EU:s ordförandeskap. Syftet med EDD är att skapa dialog om utveckling och bistånd och ta upp såväl brännande frågor som mer långsiktiga utmaningar. Själva mötet är ett öppet forum som samlar alla nivåer och grupper av utvecklingsaktörer, liksom den breda allmänheten.

Jag och några andra volontärer var där och representerade Hungerprojektet i mässans ”Development Village” där länder, institutioner, organisationer och andra presenterade sina idéer och projekt för alla besökare. Under de få timmar jag hann vara där fick jag många flashbacks från Almedalen och jag längtar redan till Almedalsveckan 2010, som lär slå alla rekord med tanke på att det är valår då…

Liksom i Almedalen så var konkurrensen om besökarnas uppmärksamhet stor på EDD. Den som lyckas hitta ett sätt att sticka ut, gärna genom att aktivera målgruppen på ett sätt som tilltalar dem, har mycket att vinna. Igår var det Gapminder och FN som enligt min mening hade lyckats bäst med det:

Jag har aldrig varit  intresserad av spel, men om Gapminder Casino någonsin blir verklighet utanför EDD får jag nog ta och tänka om:

Spelet går till såhär: man får veta var ett land befann sig på grafen i termer av förväntad livslängd och antal födda barn per kvinna år 1950, sen får man satsa på var man tror det landet befinner sig år 2009 genom att lägga ut chips på det interaktiva spelbordet. När alla hade satsat klart startas en sekvens som visar hur landet utvecklats i dessa mått fram till idag. Ett klockrent sätt att engagera människor på ett roligt sätt samtidigt som man marknadsför sin organisation och får fram sitt budskap. Jag är ett stort fan av såna win-wins!

Men det som tilltalade mig mest på hela mässan hittade jag vid FN:s monter:

Här fastnade jag ett tag, helt fantastiskt att läsa alla inspirerande ord och tankar kring fattigdomsbekämpning. Och härligt att se att “hunger”, “empowerment” och  “women’s equal rights” var återkommande ord och uttryck.

Det var en stor omställning att gå från social isolering och tentaångest till att informera om Hungerprojektet på EDD och få chansen att träffa engagerade människor som brinner för samma sak som en själv. Längtar verkligen tills jag är klar och kan jobba med utvecklingsfrågor på heltid jag med! Tills dess får jag försöka nöja mig med det jag skrev på FN-tavlan:

Nu är det packning på hög nivå som gäller. Tidigt imorgon bitti är det äntligen dags: 8 dagars sightseeing i New York!

“The old man and Google – A short story by Hans Rosling”

Highlights:
- regrets on denying his son money to buy a faster computer to work on the animation aspects of presenting the bubbles (1998)
- After presenting Gapminder in California, among congrats and praisals by the audience, Google’s Larry Page come’s up and asks “Who wrote the code?” (2006)

Mind that gap!

If 1337 arts wasn’t enough, I’ve also discovered this next site within two days.

Consider my mind blown.

Gapminder.

A stats-based website on ‘minding the gap’ between countries (eg, infant mortality rates versus income per person – or other datasets, like increased sanitation facilities, etc.)

Cool features include:

• user-defined comparisons between x and y axis (so you can compare anything against anything else – within the datasets held by the site anyway)
• each country is represented as a circle which is bigger or smaller according to population size (you can adjust the scale, of course), and is coloured according to its continent (so you can also watch intra-continental development, divergence, etc.)
• a ‘play’ function – at the bottom of the chart – which shows changes over time (some datasets stretch back to early 1800s – so you can see how countries have developed and compare with each other from back then till now-ish. China and India are generally interesting to watch.)
• the selection tool at the right allows you to focus on particular countries.
• you can ‘mind the gap’ within certain countries. China is an option for this. So you can move between what is represented at a mean international average, to what is recorded within a nation.

It’s not only interactive but also very pretty.

Choice.

If you haven’t seen Hans Rosling’s work before, have a look at his TED talks www.ted.com .

Gapminder este o organizaţie non-profit, cu sediul în Suedia care promovează o dezvoltare durabilă a ţelurilor Naţiunilor Unite, fixate pentru noul mileniu.

Ei consideră site-ul lor un adevărat muzeu care face să înţelegem lumea mai bine, prin intermediul statisticilor, aduse la un alt nivel faţă de plictisitoarele date care ne sunt practic trântite de către diversele organizaţii naţionale de statistică.

Au o secţiune de prezentări în format video, dar şi multe alte resurse pe care le poţi downloada pentru a face chiar tu prezentări…sau doar să te informezi.

Pe scurt, e un site care merită văzut măcar pentru curiozitate.

În continuare aveţi câteva screenshoturi din prezentarea Flash foarte bine organizata, in care poti chiar tu jongla cu datele. Se numeste Human Development Trends

Hans Rosling a donné une conférence au Département d’Etat des USA, conférence reprise au TED tellement passionnante que je l’ai traduite en français¹. Vous pouvez la voir ici en choisissant les sous-titres en Français (Canada)² et attendant que ma traduction soit validée au TED³. La v.o. est sur YouTube:

Cette conférence reprend le thème déjà abordés ici et là : le Tiers-Monde n’existe plus. Sa présentation contient une remarque fracassante sur la rigidité de notre “état d’esprit” :

“la vision du monde de mes étudiants correspond à la réalité du monde à l’époque où leurs professeurs sont nés.”

Rosling utilise son extraordinaire outil GapMinder pour promouvoir une vision du monde basée sur les faits : le monde a changé beaucoup plus vite, et beaucoup mieux que nous ne l’imaginons généralement.

Dans cette conférence, Rosling montre entre autres que des pays comme le Bangladesh, l’Egypte ou le Brésil, ont atteint plus rapidement les objectifs du millénaire que la Suède à l’époque, ou que le SIDA en Afrique n’est pas une généralité mais un problème à traiter localement.

Rosling profite de son audience au Département d’Etat pour placer quelques piques aux USA, mais aussi des compliments inattendus.

A voir d’urgence.

Notes:

1. Le texte traduit est ici si vous voulez le lire tranquillement, mais sans images.
2. Parce que le traducteur qui s’est attaqué à la traduction en français de France traine les pieds.
3. Les traductions des conférences TED doivent être validées par un autre traducteur, et ça prend du temps. Ce qui serait bien, ce serait que vous deveniez aussi traducteur et que vous validiez ma traduction…

Sweden’s first public TEDx event is taking place this Saturday. We’re called TEDxStockholm (I know – it’s catchy, right?) and are operating under a licence from TED – Ideas worth spreading.

We have a great line-up of speakers: from graphic designers and environmental journalists to the wizard of data bubble software himself, Hans Rosling. Actually in real life Hans Rosling is a Professor of Global Health here in Stockholm, but when he gets up on stage – then watch out! He transforms statistics to magic while also popping every pre-conceived notion you might have about them and us, the poor and the rich, the developed and the developing countries.

He uses statistics, history and facts to show us that the world cannot be divided into such simplistic categories. It is, in fact, a much more complex place. We might be stuck in our old ruts, our traditional mindsets – and he wants to drag us into the modern world and a new way of looking at it. (If you have 20  minutes, this is well worth watching. It’s a talk he gave to the US State this summer.) He is a myth-busting professor that presents his data with all the adrenaline-fuelled passion of a horse racing commentator!

Oh – and have I mentioned that this guru is one of the main attractions on Saturday?

I’ll be there watching and acting as one of the moderators for our discussion groups.

And somewhere along the way, I hope to gain a new mindset!

Hans Rosling, le créateur du merveilleux GapMinder, répond à une dizaine de questions d’internautes dans cette vidéo dont un extrait est particulièrement intéressant. De 8′ à 11′20, il répond à une question sur le système de santé US qu’Obama tente de réformer par une comparaison des systèmes de santé du monde entier à l’aide de ce graphique:

cliquer sur l'image pour le tableau interactif complet

Il y représente l’espérance de vie dans chaque pays en fonction des dépenses de santé par habitant, et colore chaque point d’une couleur correspondant à la part du PIB consacrée à la santé.

Rosling montre que le système de santé étatsunien, le plus cher en termes absolus et relatifs (15% du PIB), et le moins social de l’OCDE, est surtout peu efficace. D’autres pays comme le Portugal, le Chili et même Cuba offrent la même espérance de vie que les USA pour beaucoup moins cher. Si d’un coup de baguette magique Obama divisait par deux les coûts de la santé dans son pays, il se retrouverait dans le peloton des pays industrialisés en termes de coûts, mais plutôt en queue en termes d’espérance de vie. Pour les Etats-Unis, le challenge consiste donc surtout à améliorer de beaucoup l’espérance de vie afin de justifier leurs coûts très élevés. Peut-être qu’ils y arriveront en soignant mieux la frange de la population la plus démunie…

La Suisse (et la Norvège) est le point le plus proche des USA sur le graphique, mais le problème des coûts de la santé y est très différent. Avec une espérance de vie de 82 ans, les coûts sont objectivement justifiables en comparaison internationale. Seul le Japon fait clairement mieux. Le problème suisse, c’est le financement.

cliquer sur l'image pour le tableau interactif complet

Le graphique ci-dessus représente toujours l’espérance de vie en fonction du coût de la santé par habitant, mais ici la couleur représente la part du coût directement à charge des habitants, le reste étant pris en charge par l’Etat. Comme je l’avais montré dans “combien coûte la santé”, les primes des assurances maladie suisses ne couvrent “que” 40% du coût total de la santé, alors que dans la plupart des pays industrialisés hormis les USA, seuls 20% des coûts sont à charge des citoyens.

La comparaison avec la Norvège est frappante : pour les mêmes coûts totaux et quasiment la même espérance de vie, nos amis norvégiens ne déboursent directement que la moitié des suisses!  Le credo qui voudraient que les systèmes qui “responsabilisent” les patients fussent* plus efficaces que le systèmes sociaux ne se vérifie pas sur le graphique.

Diviser par deux les primes d’assurance maladie en Suisse ne tient qu’à un choix politique.

เสาร์ที่ 15 ส.ค. 52

วันอังคารที่จะถึงนี้ ตัวแทนจากบริษัท Elsevier ประจำประเทศสิงคโปร์จะมาขอพบ และสัมภาษณ์เกี่ยวกับการใช้ฐานข้อมูล Scopus กับงานด้านต่างๆ ของมหาวิทยาลัยมหิดล

นึกได้ว่า เมื่อเดือนที่แล้วก็มาคนหนึ่ง … มาสาธิต product ใหม่ของ Elsevier ที่มีชื่อว่า SciVal Spotlight ซึ่งเปิดตัวเมื่อปลายเดือนมิถุนายน 2552 นี้เอง เป็นระบบที่ใช้วัด ตรวจสอบ และติดตาม Research Performance ขององค์กร … โดยอาศัยข้อมูลผลงานวิจัยและการอ้างอิงผลงานวิจัยจากฐานข้อมูล Scopus เป็นพื้นฐาน … เหมาะสำหรับผู้บริหารที่จะใช้ประกอบการตัดสินใจ ให้ทุนสนับสนุน-ส่งเสริมนักวิจัยในสาขาต่างๆ หรือเปรียบเทียบข้อมูลด้านการวิจัยกับองค์กรอื่นๆที่เป็นคู่แข่ง

ดูแล้วน่าตื่นเต้นดี เพราะใช้เทคนิคที่กำลังเป็นที่นิยมในแวดวงวิทยาศาสตร์การแพทย์ สาธารณสุข และประชากรศึกษา นั่นคือ เทคนิค Visualization ซึ่งเป็นการวิเคราะห์ข้อมูลทางสถิติ แล้วแสดงผลออกมาเป็นภาพกราฟิกที่เคลื่อนไหวไปมาตามการเปลี่ยนแปลงของข้อมูล (Motion Chart) แบบ 4 มิติ วิธีนี้เป็นการนำเสนอข้อมูลที่จะทำให้เราสามารถมองเห็นภาพ จินตนาการ หรือนึกตาม และทำความเข้าใจได้ง่ายที่สุด

บรรดาโปรแกรมทำ Visualization ที่ดังมากๆ ตอนนี้ เห็นจะเป็นโปรแกรม Trendanalyzer ของ Gapminder ซึ่งต่อมาเมื่อปี 2007 Google ได้ซื้อ Trendanalyzer (ทั้งโปรแกรม และตัวคนพัฒนาโปรแกรม) ไปทำ Google Visualization API ในรูปแบบ Flash-based Motion Chart และเป็น Gadget สำหรับแจกฟรีค่ะ

เทคนิค Visualization น่าตื่นเต้นอย่างไร ชมการบรรยาย (แบบพากษ์มวย) โดยศาสตราจารย์ Hans Rosling (เจ้าของ Gapminder World) เอาเองก็แล้วกัน

“200 YEARS THAT CHANGED THE WORLD”

As I better acquaint myself with the curriculum and VELS, my challenge has become trying to integrate ICT with the teaching and learning process.

Children’s Literature Log

One of the hurdles we have to complete for our English module is a children’s literature log. We are expected to keep an ongoing diary on a couple of books every week that we have selected and read. The lecturer suggested having the reviews on hard copy and putting together a resource file. I thought about the feasibility of continuing this exercise into my practicuum and career, and realize that it would take a lot of manual work (and paper!).

Instead, I decided to design a(nother) blog to put up my reviews, and each entry will be tagged with the author’s name, the main focuses of the book and the year levels. This will allow for easy searching (compared to physically sort through the filed reviews) and will also be a resource that I can easily share with others, not just in my school or Australia, but all over the world. It will also go onto my Digital Portfolio as work that I have done.

You can view my Literature Log here.

Gapminder

An exciting resource I found for the classroom is Gapminder. It is a non-for-profit organization that has ”no political agenda behind the work”, aiming to make reliable global statistics available for us to better understand the world we live in.

On the website, you can select from 150 different variables to compare against, and the graphs created on the website can also be included into presentations and web-based documents.

Here’s an example of comparing Housing Price Index with Unemployment Rates-

Gapminder can pique the curiosity of the students, encouraging them to question and connect learning with the real world. With guidance and support by the teacher, they can work together to discover the relationship between the variables and then expand their understanding by creating a poster presentation or a written piece about their ideas.

Over the last few weeks, I was spending increasingly more time on the TED website looking up talks on design issues. It was then that I came across a few projects, absolutely stunning in breadth, undertaking and purpose, so much so that I thought I’d put it up on the blog.

The first one’s called ‘We Feel Fine’, a joint project by Jonathan Harris and Sep Kamvar. It plots the emotions of many people from all around the world through diagrammatic and statistical depictions. The design is beautifully simple and easy to understand and can give you a good idea of what’s happening in the lives of people around you. It rounds of the whole attempt by providing interesting and bizarre metrics. You can find the site here and the TED preview here. (Another interesting attempt that runs along the same lines is ‘I Want You To Want Me‘.)

The second one is an even more vast project both in terms of the kind of man power and technology that went into making it and what it hopes to achieve. It’s called the AlloSphere – a large hollow sphere that it is fit with a large host of microcontrollers connected to a supercomputer. What the AlloSphere does is that it generates various designs, constructions, materials and phenomena on an atomic scale which is then projected as a digital image onto the insides of the sphere. A bridge running along a diameter permits up to 20 people at a time to bear witness to breathtaking views that science devoid of creativity cannot hope to present to us at all. Like JoAnn Kuchera-Morin, the director of the Center for Research in Electronic Art Technology (CREATE) at UC Santa Barbara, says: “imagine architects standing in the sphere and seeing microstructures and atoms arranged in space – what if they could come up with a new construction material?” [paraphrased]. Again, here’s where you can find the TED preview.

The last one is a complete revolution in its own right and I think many people will agree when I say it’s the Gapminder by Hans Rosling. The statistics chapter in mathematics you chose to willingly forget while in school because it made you sleep in a snap – Rosling changes all of that by drawing old graphs in new ways. His sports-person commentary also adds to the pace of this lecture as he plots countries and ideas onto digital graph sheets. Find the TED talk here.

What these 3 ideas did was open me up to another idea that world is changing like no other. Like Thomas Friedman puts it, “the world is flat!” He couldn’t have been more right. This world is no longer curved around the edges and you and me are no longer strangers. With Jonathan Harris’ ‘We feel fine’, I’ll know what you’re feeling some 1000 miles away as soon as you know what I’m feeling. Kuchera-Morin’s AlloSphere will open up technology that you and me never thought we could have access to. And before you know it, Hans Rosling will have it up all on a giant graph and tell everyone what we did, what we could have done and how well we did it.

The world is no longer yours or mine, no longer subject to one war in one region amongst one group of people contending for one piece of information.  It has been globalized by just ideas. The world is ours, subject to our war that involves our people contending for the control over all information.

Jag fick nys om en person genom ett TV-program en gång. Det handlade om en professor på Karolinska Institutet. En man vid namn Hans Rosling. En YTTERST inspirerande och vettig person i mitt tycke, en stor humanist med ett stort hjärta och ett matchande intellekt.

För ett tag sen dök det upp en liten bacill, ett virus vid namn H1N1, det spred sig till människor i Mexiko och plötsligt dog några stycken. 29 stycken dog i Mexiko. 2 i USA. Mediadrevet satte igång och plötsligt hade vi en pandemi på gång. Vid det här laget har några fler människor dött  i svininfluensan som den populärt kallas. Tror mig minnas att det var runt 200 personer. Trist såklart, vi ska alla dö nångång, vi kan oftast inte välja när och de flesta dör säkert i ett virrvarr av smärta och ångest.

Inte min mening att påminna Dig om vår dödlighet, var inte alls därför jag började skriva det här.

Nej, det är snarare så att det plötsligt sod väldigt klart för mig vad informationsflödet i kombination med vår mänskliga dödsångest och girighet skapade när mediedrevet slog klorna i scoopet om svininfluensan.

Kolla in det här klippet med den enormt svengelska Herr Rosling så kommer ni förstå vad jag menar.

http://www.gapminder.org/videos/swine-flu-alert-news-death-ratio-tuberculosis/

Kanske börjar bli läge att filtrera vad du tar in? Ifrågasätta och se till vad som är troligt? Om du inte vet. Kolla på mer än ett ställe. Vem vet, du kanske blir kvitt din dödsångest den dagen?

I have to say, I was never much of a fan of statistics as a student, but that was because I wasn’t taught statistics by Hans Rosling. Anyone who wants to study or do global health should know his name as a professor on the subject at the Karolinska Institutet (Wikipedia), but even if you aren’t into global health, you should watch this video. It will change how you look at statistics forever. This, ladies and gentlemen, is why statistics needs to be taught in medical school.

Why I am a Hans Rosling fan: he’s a doctor and researcher who discovered konzo, a previously unknown paralytic disease in Africa and spent twenty years studying the epidemiology of it across remote rural areas of Africa, and found it was brought on by hunger and improperly processed cassava roots in the diet. He tells it like it is, debunking myths about the developing world and improving our understanding of healthcare in it left and right. At age 60, he’s still spry enough, excited enough and passionate enough about what he is teaching his audience to climb up on a table to point out statistics on a projector screen. He has an amazing sense of humor, even he’s giving a lecture about HIV statistics. He’s a sword swallower.

I don’t really think I need to keep going. (Wikipedia, his blog, GapMinder, book: Global Health – An Introduction)
