L’intelligence d’une ville : ses citoyens
Michel Dumais: “Tic toc! disions-nous. Bientôt la centième. Et avec la cent-unième, de nouveaux défis. Ville intelligente, disiez-vous? Je subodore le traditionnel appel de pied aux trois lettres et à une logique administrative archaïque. Et si on faisait plutôt appel à l’intelligence de ceux qui connaissent le plus leur ville, ses citoyens?
Pour régler un problème (et même à l’occasion, un «pas d’problème»), les administrations regardent du côté de ces logiciels mammouth qui, sur papier, sont censés faire tout, qui engloutissent des centaines de millions de dollars, mais qui, finalement, font les manchettes des médias parce qu’il faut y injecter encore plus d’argent. Et qui permettent aux TI d’asseoir encore plus leur contrôle sur une administration.
Bref, lorsque l’on parle de ville intelligente, plusieurs y voient le pactole. Ah! Reste que ce qui était «acceptable», hier, ne l’est plus aujourd’hui. Et que la réalisation d’une ville intelligente n’est surtout pas un défi technologique, loin de là.
LA QUESTION DU SANS-FIL
Il y a des années de cela, la simple logique eut voulu que la Ville cesse de penser «big telcos» afin de conclure rapidement une alliance avec l’organisme communautaire «Île sans fil» et ainsi favoriser le déploiement rapide sur l’île de la technologie sans fil.
Une telle alliance, un modèle dans le genre, existe.
Mais pas à Montréal. Plutôt à Québec, alors que la Ville et l’organisme communautaire «Zap Québec» travaillent main dans la main pour le plus grand bénéfice des citoyens de Québec et des touristes. Et à Montréal? On jase, on jase.
Donc, une ville intelligente. C’est une ville qui sait, à l’aide des technologies, comment harnacher ses infrastructures et les mettre au service de ses citoyens tout en réalisant des économies et en favorisant le développement durable.
C’est aussi une ville qui sait écouter et mobiliser ses citoyens, ses militants et ses entrepreneurs, tout en leur donnant des outils (comme des données utilisables) afin qu’ils puissent eux aussi créer des services destinés à leur organisation et à tous les citoyens de la ville. Sans compter que tous ces outils facilitent la prise de décisions chez les maires d’arrondissement et le comité exécutif.
Bref, une ville intelligente selon le professeur Rudolf Giffinger, c’est ça: «une économie intelligente, une mobilité intelligente, un environnement intelligent, des habitants intelligents, un mode de vie intelligent et, enfin, une administration intelligente».…
J’invite le lecteur à regarder LifeApps, une extraordinaire série télé diffusée sur le site de la chaîne AlJazeera. Le sujet: des jeunes et de moins jeunes militants, bidouilleurs, qui s’impliquent et créent des services pour leur communauté.”
OpenRFPs
Clay Johnson: “Tomorrow at CodeAcross we’ll be launching our first community-based project, OpenRFPs. The goal is to liberate the data inside of every state RFP listing website in the country. We hope you’ll find your own state’s RFP site, and contribute a parser.
The Department of Better Technology’s goal is to improve the way government works by making it easier for small, innovative businesses to provide great technology to government. But those businesses can barely make it through the front door when the RFPs themselves are stored in archaic systems, with sloppy user interfaces and disparate data formats, or locked behind paywalls.
What are a business’s current choices? They can pay for subscription based services that are either shady vendors disguised as officious sounding associations, or have less than stellar user interfaces.
The sum of these experiences? The barrier to entry is so high that the small companies who are great at technology are effectively turned away at the door. The only ones who get through are those that can afford to spend employee time scouring for the right RFPs.
But the harm to business isn’t the big harm. Government contracting becomes an overlooked area by the transparency community, (especially at the state and local level,) because the data isn’t available en-masse unless it’s paid for commercially, which comes with a restrictive usage license.”
A Natural History of Human Thinking
Tomasello argues that our prehuman ancestors, like today’s great apes, were social beings who could solve problems by thinking. But they were almost entirely competitive, aiming only at their individual goals. As ecological changes forced them into more cooperative living arrangements, early humans had to coordinate their actions and communicate their thoughts with collaborative partners. Tomasello’s “shared intentionality hypothesis” captures how these more socially complex forms of life led to more conceptually complex forms of thinking. In order to survive, humans had to learn to see the world from multiple social perspectives, to draw socially recursive inferences, and to monitor their own thinking via the normative standards of the group. Even language and culture arose from the preexisting need to work together. What differentiates us most from other great apes, Tomasello proposes, are the new forms of thinking engendered by our new forms of collaborative and communicative interaction.
A Natural History of Human Thinking is the most detailed scientific analysis to date of the connection between human sociality and cognition.”
Think Like a Commoner: A Short Introduction to the Life of the Commons
New book by David Bollier: “In our age of predatory markets and make-believe democracy, our troubled political institutions have lost sight of real people and practical realities. But if you look to the edges, ordinary people are reinventing governance and provisioning on their own terms. The commons is arising as a serious, practical alternative to the corrupt Market/State.
With graceful prose and dozens of fascinating examples, David Bollier describes the quiet revolution that is pioneering practical new forms of self-governance and production controlled by people themselves. Think Like a Commoner explains how the commons:
- Is an exploding field of DIY innovation ranging from Wikipedia and seed-sharing to community forests and collaborative consumption, and beyond;
- Challenges the standard narrative of market economics by explaining how cooperation generates significant value and human fulfillment; and
- Provides a framework of law and social action that can help us move beyond the pathologies of neoliberal capitalism.
We have a choice: Ignore the commons and suffer the ongoing private plunder of our common wealth. Or Think Like a Commoner and learn how to rebuild our society and reclaim our shared inheritance. This accessible, comprehensive introduction to the commons will surprise and enlighten you, and provoke you to action.”
Are bots taking over Wikipedia?
Kurzweil News: “As crowdsourced Wikipedia has grown too large — with more than 30 million articles in 287 languages — to be entirely edited and managed by volunteers, 12 Wikipedia bots have emerged to pick up the slack.
The bots use Wikidata — a free knowledge base that can be read and edited by both humans and bots — to exchange information between entries and between the 287 languages.
Which raises an interesting question: what portion of Wikipedia edits are generated by humans versus bots?
To find out (and keep track of other bot activity), Thomas Steiner of Google Germany has created an open-source application (and API): Wikipedia and Wikidata Realtime Edit Stats, described in an arXiv paper.
The percentages of bot vs. human edits as shown in the application is constantly changing. A KurzweilAI snapshot on Feb. 20 at 5:19 AM EST showed an astonishing 42% of Wikipedia being edited by bots. (The application lists the 12 bots.)
Anonymous vs. logged-In humans (credit: Thomas Steiner)
The percentages also vary by language. Only 5% of English edits were by bots; but for Serbian pages, in which few Wikipedians apparently participate, 96% of edits were by bots.
The application also tracks what percentage of edits are by anonymous users. Globally, it was 25 percent in our snapshot and a surprising 34 percent for English — raising interesting questions about corporate and other interests covertly manipulating Wikipedia information.
NatureNet: a model for crowdsourcing the design of citizen science systems
Paper in CSCW Companion ’14, the companion publication of the 17th ACM conference on Computer supported cooperative work & social computing: “NatureNet is citizen science system designed for collecting bio-diversity data in nature park settings. Park visitors are encouraged to participate in the design of the system in addition to collecting bio-diversity data. Our goal is to increase the motivation to participate in citizen science via crowdsourcing: the hypothesis is that when the crowd plays a role in the design and development of the system, they become stakeholders in the project and work to ensure its success. This paper presents a model for crowdsourcing design and citizen science data collection, and the results from early trials with users that illustrate the potential of this approach.”
Four Threats to American Democracy
Jared Diamond in Governance: “The U.S. government has spent the last two years wrestling with a series of crises over the federal budget and debt ceiling. I do not deny that our national debt and the prospect of a government shutdown pose real problems. But they are not our fundamental problems, although they are symptoms of them. Instead, our fundamental problems are four interconnected issues combining to threaten a breakdown of effective democratic government in the United States.
Why should we care? Let’s remind ourselves of the oft-forgotten reasons why democracy is a superior form of government (provided that it works), and hence why its deterioration is very worrisome. (Of course, I acknowledge that there are many countries in which democracy does not work, because of the lack of a national identity, of an informed electorate, or of both). The advantages of democracy include the following:
- In a democracy, one can propose and discuss virtually any idea, even if it is initially unpalatable to the government. Debate may reveal the idea to be the best solution, whereas in a dictatorship the idea would not have gotten debated, and its virtues would not have been discovered.
- In a democracy, citizens and their ideas get heard. Hence, without democracy, people are more likely to feel unheard and frustrated and to resort to violence.
- Compromise is essential to a democracy. It enables us to avoid tyranny by the majority or (conversely) paralysis of government through vetoes exercised by a frustrated minority.
- In modern democracies, all citizens can vote. Hence, government is motivated to invest in all citizens, who thereby receive the opportunity to become productive, rather than just a small dictatorial elite receiving that opportunity.
Why should we Americans keep reminding ourselves of those fundamental advantages of democracies? I would answer: not only in order to motivate ourselves to defend our democratic processes, but also because increasing numbers of Americans today are falling into the trap of envying the supposed efficiency of China’s dictatorship. Yes, it is true that dictatorships, by closing debate, can sometimes implement good policies faster than can the United States, as has China in quickly converting to lead-free gasoline and building a high-speed rail network. But dictatorships suffer from a fatal disadvantage. No one, in the 5,400 years of history of centralized government on all the continents, has figured out how to ensure that a dictatorship will embrace only good policies. Dictatorships also prevent the public debate that helps to avert catastrophic policies unparalleled in any large modern First World democracy—such as China’s quickly abolishing its educational system, sending its teachers out into the fields, and creating the world’s worst air pollution.
That is why democracy, given the prerequisites of an informed electorate and a basic sense of common interest, is the best form of government—at least, better than all the alternatives that have been tried, as Winston Churchill quipped. Our form of government is a big part of the explanation why the United States has become the richest and most powerful country in the world. Hence, an undermining of democratic processes in the United States means throwing away one of our biggest advantages. Unfortunately, that is what we are now doing, in four ways.
First, political compromise has been deteriorating in recent decades, and especially in the last five years. That deterioration can be measured as the increase in Senate rejections of presidential nominees whose approvals used to be routine, the increasing use of filibusters by the minority party, the majority party’s response of abolishing filibusters for certain types of votes, and the decline in number of laws passed by Congress to the lowest level of recent history. The reasons for this breakdown in political compromise, which seems to parallel increasing levels of nastiness in other areas of American life, remain debated. Explanations offered include the growth of television and then of the Internet, replacing face-to-face communication, and the growth of many narrowly partisan TV channels at the expense of a few broad-public channels. Even if these reasons hold a germ of truth, they leave open the question why these same trends operating in Canada and in Europe have not led to similar deterioration of political compromise in those countries as well.
Second, there are increasing restrictions on the right to vote, weighing disproportionately on voters for one party and implemented at the state level by the other party. Those obstacles include making registration to vote difficult and demanding that registered voters show documentation of citizenship when they present themselves at the polls. Of course, the United States has had a long history of denying voting rights to blacks, women, and other groups. But access to voting had been increasing in the last 50 years, so the recent proliferation of restrictions reverses that long positive trend. In addition to those obstacles preventing voter registration, the United States has by far the lowest election turnout among large First World democracies: under 60% of registered voters in most presidential elections, 40% for congressional elections, and 20% for the recent election for mayor of my city of Los Angeles. (A source of numbers for this and other comparisons that I shall cite is an excellent recent book by Howard Steven Friedman, The Measure of a Nation). And, while we are talking about elections, let’s not forget the astronomical recent increase in costs and durations of election campaigns, their funding by wealthy interests, and the shift in campaign pitches to sound bites. Those trends, unparalled in other large First World democracies, undermine the democratic prerequisite of a well-informed electorate.
A third contributor to the growing breakdown of democracy is our growing gap between rich and poor. Among our most cherished core values is our belief that the United States is a “land of opportunity,” and that we uniquely offer to our citizens the potential for rising from “rags to riches”—provided that citizens have the necessary ability and work hard. This is a myth. Income and wealth disparity in the United States (as measured by the Gini index of equality/inequality, and in other ways) is much higher in the United States than in any other large First World democracy. So is hereditary socioeconomic immobility, that is, the probability that a son’s relative income will just mirror his father’s relative income, and that sons of poor fathers will not become wealthy. Part of the reason for those depressing facts is inequality of educational opportunities. Children of rich Americans tend to receive much better educations than children of poor Americans.
That is bad for our economy, because it means that we are failing to develop a large fraction of our intellectual capital. It is also bad for our political stability, because poor parents who correctly perceive that their children are not being given the opportunity to succeed may express their resulting frustration in violence. Twice during my 47 years of residence in Los Angeles, in 1964 and 1993, frustration in poor areas of Los Angeles erupted into violence, lootings, and killings. In the 1993 riots, when police feared that rioters would spill into the wealthy suburb of Beverly Hills, all that the outnumbered police could do to protect Beverly Hills was to string yellow plastic police tape across major streets. As it turned out, the rioters did not try to invade Beverly Hills in 1993. But if present trends causing frustration continue, there will be more riots in Los Angeles and other American cities, and yellow plastic police tape will not suffice to contain the rioters.
The remaining contributor to the decline of American democracy is the decline of government investment in public purposes, such as education, infrastructure, and nonmilitary research and development. Large segments of the American populace deride government investment as “socialism.” But it is not socialism. On the contrary, it is one of the longest established functions of government. Ever since the rise of the first governments 5,400 years ago, governments have served two main functions: to maintain internal peace by monopolizing force, settling disputes, and forbidding citizens to resort to violence in order to settle disputes themselves; and to redistribute individual wealth for investing in larger aims—in the worst cases, enriching the elite; in the best cases, promoting the good of society as a whole. Of course, some investment is private, by wealthy individuals and companies expecting to profit from their investments. But many potential payoffs cannot attract private investment, either because the payoff is so far off in the future (such as the payoff from universal primary school education), or because the payoff is diffused over all of society rather than concentrated in areas profitable to the private investor (such as diffused benefits of municipal fire departments, roads, and broad education). Even the most passionate American supporters of small government do not decry as socialism the funding of fire departments, interstate highways, and public schools.
Mindless – Why Smarter Machines are Making Dumber Humans
New book by Simon Head: “The tools of corporate efficiency—expert systems, databases, and operations management—have improved our lives significantly, but with a cost: they’re turning us into mindless drones.
We live in the age of Computer Business Systems (CBSs)—the highly complex, computer-intensive management programs on which large organizations increasingly rely. In Mindless, Simon Head argues that these systems have come to trump human expertise, dictating the goals and strategies of a wide array of businesses, and de-skilling the jobs of middle class workers in the process. CBSs are especially dysfunctional, Head argues, when they apply their disembodied expertise to transactions between humans, as in health care, education, customer relations, and human resources management. And yet there are industries with more human approaches, as Head illustrates with specific examples, whose lead we must follow and extend to the mainstream American economy.
Mindless illustrates the shortcomings of CBS, providing an in-depth and disturbing look at how human dignity is slipping as we become cogs on a white collar assembly line.”
Can Twitter Predict Major Events Such As Mass Protests?
Emerging Technology From the arXiv : “The idea that social media sites such as Twitter can predict the future has a controversial history. In the last few years, various groups have claimed to be able to predict everything from the outcome of elections to the box office takings for new movies.
It’s fair to say that these claims have generated their fair share of criticism. So it’s interesting to see a new claim come to light.
Today, Nathan Kallus at the Massachusetts Institute of Technology in Cambridge says he has developed a way to predict crowd behaviour using statements made on Twitter. In particular, he has analysed the tweets associated with the 2013 coup d’état in Egypt and says that the civil unrest associated with this event was clearly predictable days in advance.
It’s not hard to imagine how the future behaviour of crowds might be embedded in the Twitter stream. People often signal their intent to meet in advance and even coordinate their behaviour using social media. So this social media activity is a leading indicator of future crowd behaviour.
That makes it seem clear that predicting future crowd behaviour is simply a matter of picking this leading indicator out of the noise.
Kallus says this is possible by mining tweets for any mention of future events and then analysing trends associated with them. “The gathering of crowds into a single action can often be seen through trends appearing in this data far in advance,” he says.
It turns out that exactly this kind of analysis is available from a company called Recorded Future based in Cambridge, which scans 300,000 different web sources in seven different languages from all over the world. It then extracts mentions of future events for later analysis….
The bigger question is whether it’s possible to pick out this evidence in advance. In other words, is possible to make predictions before the events actually occur?
That’s not so clear but there are good reasons to be cautious. First of all, while it’s possible to correlate Twitter activity to real protests, it’s also necessary to rule out false positives. There may be significant Twitter trends that do not lead to significant protests in the streets. Kallus does not adequately address the question of how to tell these things apart.
Then there is the question of whether tweets are trustworthy. It’s not hard to imagine that when it comes to issues of great national consequence, propaganda, rumor and irony may play a significant role. So how to deal with this?
There is also the question of demographics and whether tweets truly represent the intentions and activity of the population as a whole. People who tweet are overwhelmingly likely to be young but there is another silent majority that plays hugely important role. So can the Twitter firehose really represent the intentions of this part of the population too?
The final challenge is in the nature of prediction. If the Twitter feed is predictive, then what’s needed is evidence that it can be used to make real predictions about the future and not just historical predictions about the past.
We’ve looked at some of these problems with the predictive power of social media before and the challenge is clear: if there is a claim to be able to predict the future, then this claim must be accompanied by convincing evidence of an actual prediction about an event before it happens.
Until then, it would surely be wise to be circumspect about the predictive powers of Twitter and other forms of social media.
