What Restaurant Reviews Reveal About Cities

Curated on Posted on by Stefaan Verhulst

Linda Poon at CityLab: “Online review sites can tell you a lot about a city’s restaurant scene, and they can reveal a lot about the city itself, too.

Researchers at MIT recently found that information about restaurants gathered from popular review sites can be used to uncover a number of socioeconomic factors of a neighborhood, including its employment rates and demographic profiles of the people who live, work, and travel there.

A report published last week in the Proceedings of the National Academy of Sciences explains how the researchers used information found on Dianping—a Yelp-like site in China—to find information that might usually be gleaned from an official government census. The model could prove especially useful for gathering information about cities that don’t have that kind of reliable or up-to-date government data, especially in developing countries with limited resources to conduct regular surveys….

Zheng and her colleagues tested out their machine-learning model using restaurant data from nine Chinese cities of various sizes—from crowded ones like Beijing, with a population of more than 10 million, to smaller ones like Baoding, a city of fewer than 3 million people.

They pulled data from 630,000 restaurants listed on Dianping, including each business’s location, menu prices, opening day, and customer ratings. Then they ran it through a machine-learning model with official census data and with anonymous location and spending data gathered from cell phones and bank cards. By comparing the information, they were able to determine where the restaurant data reflected the other data they had about neighborhoods’ characteristics.

They found that the local restaurant scene can predict, with 95 percent accuracy, variations in a neighborhood’s daytime and nighttime populations, which are measured using mobile phone data. They can also predict, with 90 and 93 percent accuracy, respectively, the number of businesses and the volume of consumer consumption. The type of cuisines offered and kind of eateries available (coffeeshop vs. traditional teahouses, for example), can also predict the proportion of immigrants or age and income breakdown of residents. The predictions are more accurate for neighborhoods near urban centers as opposed to those near suburbs, and for smaller cities, where neighborhoods don’t vary as widely as those in bigger metropolises….(More)”.

From Hippocrates to Artificial Intelligence: Moving Towards a Collective Intelligence

Curated on Posted on by Stefaan Verhulst

Carlos María Galmarini at Open Mind: “Modern medicine is based upon the work of Hippocrates and his disciples and is compiled in more than 70 books comprising the Hippocratic body of work. In its essence, these writings declare that any illness originates with natural causes. Therefore, medicine must be based on detailed observation, reason, and experience in order to establish a diagnosis, prognosis, and treatment. The Hippocratic tradition stresses the importance of the symptoms and the clinical exam. As a result, medicine abandoned superstition and the magic performed by priest-doctors, and it was transformed into a real, experience-based science….

A complementary combination of both intelligences (human and artificial) could help overcome the other’s shortcomings and limitations. As we incorporate intelligent technologies into medical processes, a new, more powerful form of collaboration will emerge. Analogous to the past when the automation of human tasks completely changed the known world and ignited an evolution in the offering of products and services, the combination of human and artificial intelligence will create a new type of collective intelligence capable of building more efficient organizations, and in the healthcare industry, it will be able to solve problems that until now have been unfathomable to the human mind alone.

Finally, it is worth remembering that fact based sciences are divided into natural and human disciplines. Medicine occupies a special place, straddling both. It can be difficult to establish the similarities between a doctor who works, for example, with rules defined by specific clinical trials and a traditional family practitioner. The former would be more related to a natural science, and the latter with a more human science – “the art of medicine.”

The combination of human and artificial intelligence in a new type of collective intelligence will enable doctors themselves to be a combination of the two. In other words, the art of medicine – human science – based on the analysis of big data – natural science. A new collective intelligence working on behalf of a wiser medicine….(More)”.

Improving access to information and restoring the public’s faith in democracy through deliberative institutions

Curated on Posted on by Stefaan Verhulst

Katherine R. Knobloch at Democratic Audit: “Both scholars and citizens have begun to believe that democracy is in decline. Authoritarian power grabs, polarising rhetoric, and increasing inequality can all claim responsibility for democratic systems that feel broken. Democracy depends on a polity who believe that their engagement matters, but evidence suggests democratic institutions have become unresponsive to the will of the public. How can we restore faith in self-government when both research and personal experience tell us that the public is losing power, not gaining it?

Deliberative public engagement

Deliberative democracy offers one solution, and it’s slowly shifting how the public engages in political decision-making. In Oregon, the Citizens’ Initiative Review(CIR) asks a group of randomly selected voters to carefully study public issues and then make policy recommendations based on their collective experience and insight. In Ireland, Citizens’ Assemblies are being used to amend the country’s constitution to better reflect changing cultural norms. In communities across the world, Participatory Budgeting is giving the public control over local government spending. Far from squashing democratic power, these deliberative institutions bolster it. They exemplify a new wave in democratic government, one that aims to bring community members together across political and cultural divides to make decisions about how to govern themselves.

Though the contours of deliberative events vary, most share key characteristics. A diverse body of community members gather together to learn from experts and one another, think through the short- and long-term implications of different policy positions, and discuss how issues affect not only themselves but their wider communities. At the end of those conversations, they make decisions that are representative of the diversity of participants and their ideas and which have been tested through collective reasoning….(More)”.

Introducing the Partner State: Public-Civil Partnerships for a Better City

Curated on Posted on by Stefaan Verhulst

Blog by Dirk Holemans: “Imagine: an urban politician wants to insist that some streets become car-free during summer. Even if there are good reasons – better air quality, kids get room to play – the result is quite predictable. The residents of those designated streets would revolt, for different reasons. Some would feel ignored as citizens, others would stand by their right to drive their car to their door, etc. Result: the politician has to withdraw the proposal, disappointed by these negative reactions. So, the gap between politics and people widens further.

But what happens if an independent network of collaborating citizens, businesses and local organisations, supported by the city government, develops a positive narrative for the idea of a Living Street? If they emphasise that a Living Street will be the sustainable place that inhabitants have always dreamed of? What if they offer people who are interested and want to test the idea on their street the possibility to do just that, if they can convince their neighbours to support this potentially great idea? In the city of Ghent we know the answer to this question. Since 2013, in the summer several streets have been transformed into car-free ‘places’ for the community, creating room for picnic benches, playgrounds for children, etc.

The Living Streets is not a top-down project, nor a bottom-up citizens’ initiative. It’s a form of co-creation between residents, the city and other organisations. Residents join forces, get to know each other better and go to work on the challenges of their street (more meeting space, isolation of older residents, traffic, unsafe street layout etc). For the city government, Living Streets are a testing ground for parking solutions, street furniture and the search for new forms of resident participation. The civil servants also roll up their sleeves. They seek solutions, help mediate in conflicts, make their expertise available and translate experiences into new policies.

Living Streets are one of the examples of how the city of Ghent, just as other cities like Bologna and Barcelona, is changing the traditional top-down politics of our modern society. In the latter approach, the provision of services, the introduction of innovations or management of resources, tend to be presented as a stark choice between state organisations or market mechanisms. This binary division ignores a crucial third possibility – that of interventions by autonomous citizens – and underestimates the many possibilities of citizens and (local) authorities working together….(More)”.

New technology and ‘old’ think tanks

Curated on Posted on by Stefaan Verhulst

Article by Tom Ascott: ‘Expert or academic carries out research. Generates rigorous 40-page report. Comms officer is asked to promote said report. Launch event, press release, tweets. Maybe a video. Maybe an infographic’. This is formula for how think tanks seek to influence policy matters. It is how they build, maintain and increase their credibility. While it has arguably worked since the expansion of the think tank community following the Cold War, this model of disseminating information is now fraying.

It is not a sustainable model because it is largely, and in some ways even designed to be, inaccessible to a larger and now increasingly inquisitive public. This inaccessibility is only accentuated by the large number of institutes specialising in niche subjects, which are often more agile and better able to leverage technology to their advantage. Tastes also change: for many of today’s potential punters, the enforced networking associated with think tank events may be considered a negative experience; being able to watch lectures and conferences from home, alone, may now be considered of greater benefit.

The publication of written reports and holding launch events, unlike broader communications methods, are often targeting specific policymakers or stakeholders. In the short term, this strategy may work for think tanks, in the sense that they can address their core audiences. Still, the model faces two main hurdles.

One is providing policymakers with what they need. Paul C Avey and Michael C Desch, two US-based academics, found in their study ‘What Do Policymakers Want From Us?’ that ‘the only methodology that more than half of the respondents characterised as “not very useful” or “not useful at all” was formal models’. The respondents in their study thought that the best policy advice came from practitioners or journalists, those looking at underlying causes. Yet some ‘think tankers’ continue to take a dim view of journalism, for the very reasons which make journalism important: rapidly responding to developing events, and offering a broader perspective, usually shorn of the uncertainties inherent in deeper knowledge or analysis.

The second, broader, problem is how think tanks are perceived. US President Barack Obama famously ‘disdain[ed]’ foreign policy establishments and institutes, and those who are not engaged with them perceive them as being elitist….(More)”.

How can Indigenous Data Sovereignty (IDS) be promoted and mainstreamed within open data movements?

Curated on Posted on by Stefaan Verhulst

OD Mekong Blog: “Considering Indigenous rights in the open data and technology space is a relatively new concept. Called “Indigenous Data Sovereignty” (IDS), it is defined as “the right of Indigenous peoples to govern the collection, ownership, and application of data about Indigenous communities, peoples, lands, and resources”, regardless of where the data is held or by whom. By default, this broad and all-encompassing framework bucks fundamental concepts of open data, and asks traditional open data practitioners to critically consider how open data can be used as a tool of transparency that also upholds equal rights for all…

Four main areas of concern and relevant barriers identified by participants were:

Self-determination to identify their membership

  • National governments in many states, particularly across Asia and South America, still do not allow for self-determination under the law. Even when legislation offers some recognition these are scarcely enforced, and mainstream discourse demonises Indigenous self-determination.
  • However, because Indigenous and ethnic minorities frequently face hardships and persecution on a daily basis, there were concerns about the applicability of data sovereignty at the local levels.

Intellectual Property Protocols

  • It has become the norm in the everyday lives of people for big tech companies to extract data in excessive amounts. How do disenfranchised communities combat this?
  • Indigenous data is often misappropriated to the detriment of Indigenous peoples.
  • Intellectual property concepts, such as copyright, are not an ideal approach for protecting Indigenous knowledge and intellectual property rights because they are rooted in commercialistic ideals that are difficult to apply to Indigenous contexts. This is especially so because many groups do not practice commercialization in the globalized context. Also, as a concept based on exclusivity (i.e., when licenses expire knowledge gets transferred over as public goods), it doesn’t take into account the collectivist ideals of Indigenous peoples.

Data Governance

  • Ultimately, data protection is about protecting lives. Having the ability to use data to direct decisions on Indigenous development places greater control in the hands of Indigenous peoples.
  • National governments are barriers due to conflicts in sovereignty interests. Nation-state legal systems are often contradictory to customary laws, and thus don’t often reflect rights-based approaches.

Consent — Free Prior and Informed Consent (FPIC)

  • FPIC, referring to a set of principles that define the process and mechanisms that apply specifically to Indigenous peoples in relation to the exercise of their collective rights, is a well-known phrase. They are intended to ensure that Indigenous peoples are treated as sovereign peoples with their own decision-making power, customary governance systems, and collective decision-making processes, but it is questionable as to what level one can ensure true FPIC in the Indigenous context.²
  • It remains a question as too how effectively due diligence can be applied to research protocols, so as to ensure that the rights associated with FPIC and the UNDRIP framework are upheld….(More)”.

Nudging Us To Health

Curated on Posted on by Stefaan Verhulst

Blog by Chuck Dinerstein: “Policymakers love nudges – predictably altering people’s behavior without forbidding choices or changing economic incentives. That is especially true for our food choices since we all eat, and it is clear that diet does have some effect on our health. The “promise to improve people’s diet at a fraction of the cost of economic incentives or education programs without imposing new taxes or constraints on business or consumers,” is a have my cake and eat it world. A study by the masters of understanding our behavior, the marketers, sheds light on which nudges work best….

Cognitive nudges include those often-invoked nutritional labels or evaluative labels that skip the verbiage and are green for buy, red for put it back on the shelf, and yellow for it’s up to you. Visibility enhancements refer to getting the item into your visual field at the right time and place, like eye-level on the shelf or in the check-out line. Nudges that appeal to our feelings include all the images making food appealing, think food porn, or simple slogans, e.g., “natural,” “healthy choice,” or ”just like mama made.” (Assuming mom was a good cook). As the researchers point out, there are no labels on foods that promote guilt or concern as we see on tobacco’s Surgeon General warnings. Finally, there are behavioral nudges that make one choice easier than another,  precut fruits and vegetables, or big utensils for vegetables, and tiny ones for fried chicken. It also includes smaller plates that might look fuller or large drink glasses that are 80% ice

Here is the graphic of their findings:

Graphic by Pierre Chandon

  • Nudges do move behavior, although the effect is small, a change of about 124 calories, or in the author’s words “eight fewer teaspoons of sugar.” For those who do not eat sugar by the spoonful, you might consider this to be 1 ½ Jelly Filled Munchkins.
  • As the graph shows, appealing to our intellect works the least well, appeals to our emotions are twice as effective, and making it easy to do the “right thing” works the best, five-fold better, than educating us.
  • Nudges are better at decreasing bad choices than increasing good ones. “it is easier to make people eat less chocolate cake than to make them eat more vegetables…” In fact, total eating was basically unaffected by nudges, again as the authors write, “this finding is consistent with what we know about the difficulty – perhaps even pointlessness – of hypocaloric diets.”
  • The effect of nudges is a lot less when you’re shopping than when you’re eating.
  • The effect of nudges in isolation seems more pronounced statistically speaking than when considered in conjunction with where they take place and other contextual information.
  • Nudges were equally effective, or ineffective, with adults and children; although you might expect that adults would be more responsive given their presumably better understanding of diet and health

The study makes two points. First, nudges can move behavior a little bit, and the fact that it has few recognized costs means that policymakers will continue to utilize them. Second, it provides an analytic framework highlighting areas where the evidence is scant and could, I suggest, nudge researchers to explore….(More)”.

How an AI Utopia Would Work

Curated on Posted on by Stefaan Verhulst

Sami Mahroum at Project Syndicate: “…It is more than 500 years since Sir Thomas More found inspiration for the “Kingdom of Utopia” while strolling the streets of Antwerp. So, when I traveled there from Dubai in May to speak about artificial intelligence (AI), I couldn’t help but draw parallels to Raphael Hythloday, the character in Utopia who regales sixteenth-century Englanders with tales of a better world.

As home to the world’s first Minister of AI, as well as museums, academies, and foundations dedicated to studying the future, Dubai is on its own Hythloday-esque voyage. Whereas Europe, in general, has grown increasingly anxious about technological threats to employment, the United Arab Emirates has enthusiastically embraced the labor-saving potential of AI and automation.

There are practical reasons for this. The ratio of indigenous-to-foreign labor in the Gulf states is highly imbalanced, ranging from a high of 67% in Saudi Arabia to a low of 11% in the UAE. And because the region’s desert environment cannot support further population growth, the prospect of replacing people with machines has become increasingly attractive.

But there is also a deeper cultural difference between the two regions. Unlike Western Europe, the birthplace of both the Industrial Revolution and the “Protestant work ethic,” Arab societies generally do not “live to work,” but rather “work to live,” placing a greater value on leisure time. Such attitudes are not particularly compatible with economic systems that require squeezing ever more productivity out of labor, but they are well suited for an age of AI and automation….

Fortunately, AI and data-driven innovation could offer a way forward. In what could be perceived as a kind of AI utopia, the paradox of a bigger state with a smaller budget could be reconciled, because the government would have the tools to expand public goods and services at a very small cost.

The biggest hurdle would be cultural: As early as 1948, the German philosopher Joseph Pieper warned against the “proletarianization” of people and called for leisure to be the basis for culture. Westerners would have to abandon their obsession with the work ethic, as well as their deep-seated resentment toward “free riders.” They would have to start differentiating between work that is necessary for a dignified existence, and work that is geared toward amassing wealth and achieving status. The former could potentially be all but eliminated.

With the right mindset, all societies could start to forge a new AI-driven social contract, wherein the state would capture a larger share of the return on assets, and distribute the surplus generated by AI and automation to residents. Publicly-owned machines would produce a wide range of goods and services, from generic drugs, food, clothes, and housing, to basic research, security, and transportation….(More)”.

How I Learned to Stop Worrying and Love the GDPR

Curated on Posted on by Stefaan Verhulst

Ariane Adam at DataStewards.net: “The General Data Protection Regulation (GDPR) was approved by the EU Parliament on 14 April 2016 and came into force on 25 May 2018….

The coming into force of this important regulation has created confusion and concern about penalties, particularly in the private sector….There is also apprehension about how the GDPR will affect the opening and sharing of valuable databases. At a time when open data is increasingly shaping the choices we make, from finding the fastest route home to choosing the best medical or education provider, misinformation about data protection principles leads to concerns that ‘privacy’ will be used as a smokescreen to not publish important information. Allaying the concerns of private organisations and businesses in this area is particularly important as often the datasets that most matter, and that could have the most impact if they were open, do not belong to governments.

Looking at the regulation and its effects about one year on, this paper advances a positive case for the GDPR and aims to demonstrate that a proper understanding of its underlying principles can not only assist in promoting consumer confidence and therefore business growth, but also enable organisations to safely open and share important and valuable datasets….(More)”.

How credit unions could help people make the most of personal data

Curated on Posted on by Stefaan Verhulst

Dylan Walsh at MIT Sloan: “In May of 2018, the EU adopted the General Data Protection Regulation, referred to by The New York Timesas “the world’s toughest rules to protect people’s online data.” Among its many safeguards, the GDPR gave individuals ownership of their personal data and thereby restricted its collection and use by businesses.

“That’s a good first start,” said Alex Pentland, a co-creator of the MIT Media Lab who played a foundational role in the development of the GDPR. “But ownership isn’t enough. Simply having the rights to your data doesn’t allow you to do much with it.” In response to this shortcoming, Pentland and his team have proposed the establishment of data cooperatives.

The idea is conceptually straightforward: Individuals would pool their personal data in a single institution — just as they pool money in banks — and that institution would both protect the data and put it to use. Pentland and his team suggest credit unions as one type of organization that could fill this role. And while companies would need to request permission to use consumer data, consumers themselves could request analytic insights from the cooperative. Lyft drivers, for instance, might compare their respective incomes across routes, and ride-share passengers could compare how much they pay relative to other cooperative members….

Several states have now asked credit unions to look into the idea of data cooperatives, but the model has yet to gain a foothold. “Credit unions are conservative,” Pentland said. But assuming the idea gains traction, the infrastructure won’t be difficult to build. Technology exists to automatically record and organize all the data that we give to companies; and credit unions, which have 100 million members nationwide, possess charters readymade to take on data management….(More)”.
