Tendrils of Learning - Draft Slides for Bogota Preso

By Stephen Downes - Stephen's Web. Tendrils of Learning - Draft Slides for Bogota Preso
It's hard to believe that it has only been a year since I first visited Colombia. Now Jay Cross and Nancy White are enjoying Bogota's hospitality. Christian Stracke, Tony Bates and Christopher Dede will also be there. I wish I were there! But at least I have - via the conference website - access to a live streaming video feed of the morning sessions. Diego Leal writes, "We will transmit the morning sessions through the Colombia Aprende educational portal. We will have an english video/audio signal available, so if you are interested in any of the subjects scheduled, please feel welcome to follow the online transmission. The streaming URL will be active on Wednesday. More...

Le Congrès des États-Unis

Accueil - Vie PubliqueLe Congrès des États-Unis se compose de deux assemblées.
La Chambre des représentants (House of Representatives) comprend 435 membres élus pour deux ans au suffrage universel direct, selon le scrutin uninominal majoritaire à un tour dans le cadre de circonscriptions à l’intérieur des États, chaque État disposant d’un nombre de représentants proportionnel à sa population. Ses membres se trouvent donc en campagne électorale quasi-permanente.
Le Sénat (United States Senate) comprend 100 membres, deux par État, élus pour six ans au scrutin universel direct majoritaire uninominal à un tour. Il se renouvelle par tiers tous les deux ans.
Les deux chambres partagent de manière égale le pouvoir législatif, mais le Sénat dispose de pouvoirs particuliers : il autorise la ratification des traités et approuve les nominations aux emplois publics les plus importants – membres de la Cour suprême, ambassadeurs, hauts fonctionnaires.
Le Congrès ne peut mettre en cause la responsabilité de l’exécutif, sauf en cas de procédure d’impeachment (« mise en accusation », pouvant aboutir à la destitution) du Président. Il exerce un contrôle permanent de l’activité des administrations. Il utilise les auditions publiques (hearings), les enquêtes, et dispose de l’équivalent de notre Cour des comptes pour contrôler l’utilisation des deniers publics (le General Accounting Office). Il dispose par ailleurs de la plénitude du pouvoir d’initiative législative et budgétaire.
Parallèlement, le Président ne peut dissoudre les chambres du Congrès et et son administration n’est pas responsable politiquement devant elles. Il communique avec le Congrès par message et peut s’opposer à certaines de ses décisions par la procédure de veto. Le parlement occupe donc aux États-Unis une place très importante, du fait d’une forte séparation des pouvoirs, qui contraint le Président à collaborer en permanence avec lui. Plus...

Hopewell Rocks

By Stephen Downes - Stephen's Web. Hopewell Rocks

Delegates at the conference here in Moncton took a break and went on a field trip to the Hopewell Rocks, about half an hour south of the city. The rocks are a scenic part of the shore of the Bay of Fundy, home of the highest tides in the world. It's neat to walk on the seabed knowing that it was just covered with 40 feet of water.

We are now officially into the dog days of August. Yesterday I celebrated the season by cycling to Havelock (a town about 50 km west of Moncton) and back. Pictured above is the beautiful Canaan River, which flows about 10 km north of Havelock. Stephen Downes, Flickr August 6, 2007 [Link] [Tags: ]. More...

How Madison Avenue Is Wasting Millions On a Deserted Second Life

"There was nobody else around." He teleported over to the Aloft Hotel, a virtual prototype for a real-world chain being developed by the owners of the W. It was deserted, almost creepy. "I felt like I was in The Shining." Related: Karl Kapp describes a session in ProtoSphere (click under 'solutions' to find the unlinkable Flash page describing ProtoSphere). More...

Study: Food in McDonald's Wrapper Tastes Better to Kids

By Stephen Downes - Stephen's Web. Study: Food in McDonald's Wrapper Tastes Better to Kids
On the CTV newscast this morning the anchors kept trying to deflect the impact of this by citing 'the bright colours' used on the McDonald's products. What they don't want people to see is that advertising to children is harmful, not simply because it gets them to buy products that are bad for them, but because it distorts the way they perceive the world. I make a special attempt to shun and disparage brands that advertise to children, because I think that their marketing tactics are particularly distasteful. More...

Les institutions des États-Unis

Accueil - Vie PubliqueLes Pères fondateurs l’'avaient dit et écrit clairement : la priorité n’était pas de mettre en place un système efficace, mais d’empêcher la tyrannie. D’où les multiples mécanismes de séparation des pouvoirs, de contre-pouvoirs et de freins et contrepoids. Plus...

Putting Canadian "Piracy" in Perspective - The Sources

By Stephen Downes - Stephen's Web. Putting Canadian "Piracy" in Perspective - The Sources
The video isn't that great, and I hate the background music, but the story it tells is worth the ten minutes. In a nutshell, the numerous reports we have been reading in Canadian and other media about how Canada is a haven for copyright pirates is simply false. Not true. Not even remotely true. And while Michael Geist neatly makes the case against the lobbyists - notably the Canadian Recording Industry Association (CRIA), which represents mostly U.S. interests in Canada (the Canadian music publishers and artists have long since left) - what I would like to question is how these false reports end up in our newspapers and (hence) influencing public policy. Almost every day, it seems, people hold up the traditional media as the paragon of reliability the web, the blogosphere and things like Wikipedia ought to be aspiring to. But even more frequently, I see examples of blatant and deliberate falsehood in the traditional media. True, there is no point shouting at them - they have no intent to listen. More...

Rolling the Dice

By Stephen Downes - Stephen's Web. Rolling the Dice
Backfence - an experiment in online local journalism that attracted $3 million in seed money and employed as many as 25 people - is closing down. It couldn't get the readership, and more importantly, it couldn't get the advertising dollars. What does this say about the future of grassroots local journalism - and more broadly, about user-driven initiatives in general. Well, first, if you're in them to make money, you're probably in them for the wrong reasons. There are, as we see in this article, various successful local journalism projects - but none of which would ever hope to recoup a $3 million investment. And second, in order to stay small, you need to get big - to create a chain (or a network?) of similar sites, to attract national news and national advertising. Because that's where the money is.
