The Mathematics of How Connections Become Global


Kelsey Houston-Edwards at Scientific American: “When you hit “send” on a text message, it is easy to imagine that the note will travel directly from your phone to your friend’s. In fact, it typically goes on a long journey through a cellular network or the Internet, both of which rely on centralized infrastructure that can be damaged by natural disasters or shut down by repressive governments. For fear of state surveillance or interference, tech-savvy protesters in Hong Kong avoided the Internet by using software such as FireChat and Bridgefy to send messages directly between nearby phones.

These apps let a missive hop silently from one phone to the next, eventually connecting the sender to the receiver—the only users capable of viewing the message. The collections of linked phones, known as mesh networks or mobile ad hoc networks, enable a flexible and decentralized mode of communication. But for any two phones to communicate, they need to be linked via a chain of other phones. How many people scattered throughout Hong Kong need to be connected via the same mesh network before we can be confident that crosstown communication is possible?

A branch of mathematics called percolation theory offers a surprising answer: just a few people can make all the difference. As users join a new network, isolated pockets of connected phones slowly emerge. But full east-to-west or north-to-south communication appears all of a sudden as the density of users passes a critical and sharp threshold. Scientists describe such a rapid change in a network’s connectivity as a phase transition—the same concept used to explain abrupt changes in the state of a material such as the melting of ice or the boiling of water.

Percolation theory examines the consequences of randomly creating or removing links in such networks, which mathematicians conceive of as a collection of nodes (represented by points) linked by “edges” (lines). Each node represents an object such as a phone or a person, and the edges represent a specific relation between two of them. The fundamental insight of percolation theory, which dates back to the 1950s, is that as the number of links in a network gradually increases, a global cluster of connected nodes will suddenly emerge….(More)”.

Using Data and Citizen Science for Gardening Success


Article by Elizabeth Waddington: “…Data can help you personally by providing information you can use. And it also allows you to play a wider role in boosting understanding of our planet and tackling the global crises we face in a collaborative way. Consider the following examples.

Grow Observatory

This is one great example of data gathering and citizen science. Grow Observatory is a European citizen’s observatory through which people work together to take action on climate change, build better soil, grow healthier food and corroborate data from the new generation of Copernicus satellites.

Twenty-four Grow communities in 13 European countries created a network of over 6,500 ground-based soil sensors and collected a lot of soil-related data. And many insights have helped people learn about and test regenerative food growing techniques.

On their website, you can explore sensor locations, or make use of dynamic soil moisture maps. With the Grow Observatory app, you can get crop and planting advice tailored to your location, and get detailed, science-based information about regenerative growing practices. Their water planner also allows small-scale growers to learn more about how much water their plants will need in their location over the coming months if they live in one of the areas which currently have available data…

Cooperative Citizen Science: iNaturalist, Bioblitzes, Bird Counts, and More

Wherever you live, there are many different ways to get involved and help build data. From submitting observations on wildlife in your garden through apps like iNaturalist to taking part in local Bioblitzes, bird counts, and more – there are plenty of ways we can collect data that will help us – and others – down the road.

Collecting data through our observations, and, crucially, sharing that data with others can help us create the future we all want to see. We, as individuals, can often feel powerless. But citizen science projects help us to see the collective power we can wield when we work together. Modern technology means we can be hyper-connected, and affect wider systems, even when we are alone in our own gardens….(More)”

Lessons from all democracies


David Stasavage at Aeon: “Today, many people see democracy as under threat in a way that only a decade ago seemed unimaginable. Following the fall of the Berlin Wall in 1989, it seemed like democracy was the way of the future. But nowadays, the state of democracy looks very different; we hear about ‘backsliding’ and ‘decay’ and other descriptions of a sort of creeping authoritarianism. Some long-established democracies, such as the United States, are witnessing a violation of governmental norms once thought secure, and this has culminated in the recent insurrection at the US Capitol. If democracy is a torch that shines for a time before then burning out – think of Classical Athens and Renaissance city republics – it all feels as if we might be heading toward a new period of darkness. What can we do to reverse this apparent trend and support democracy?

First, we must dispense with the idea that democracy is like a torch that gets passed from one leading society to another. The core feature of democracy – that those who rule can do so only with the consent of the people – wasn’t invented in one place at one time: it evolved independently in a great many human societies.

Over several millennia and across multiple continents, early democracy was an institution in which rulers governed jointly with councils and assemblies of the people. From the Huron (who called themselves the Wendats) and the Iroquois (who called themselves the Haudenosaunee) in the Northeastern Woodlands of North America, to the republics of Ancient India, to examples of city governance in ancient Mesopotamia, these councils and assemblies were common. Classical Greece provided particularly important instances of this democratic practice, and it’s true that the Greeks gave us a language for thinking about democracy, including the word demokratia itself. But they didn’t invent the practice. If we want to better understand the strengths and weaknesses of our modern democracies, then early democratic societies from around the world provide important lessons.

The core feature of early democracy was that the people had power, even if multiparty elections (today, often thought to be a definitive feature of democracy) didn’t happen. The people, or at least some significant fraction of them, exercised this power in many different ways. In some cases, a ruler was chosen by a council or assembly, and was limited to being first among equals. In other instances, a ruler inherited their position, but faced constraints to seek consent from the people before taking actions both large and small. The alternative to early democracy was autocracy, a system where one person ruled on their own via bureaucratic subordinates whom they had recruited and remunerated. The word ‘autocracy’ is a bit of a misnomer here in that no one in this position ever truly ruled on their own, but it does signify a different way of organising political power.

Early democratic governance is clearly apparent in some ancient societies in Mesopotamia as well as in India. It flourished in a number of places in the Americas before European conquest, such as among the Huron and the Iroquois in the Northeastern Woodlands and in the ‘Republic of Tlaxcala’ that abutted the Triple Alliance, more commonly known as the Aztec Empire. It was also common in precolonial Africa. In all of these societies there were several defining features that tended to reinforce early democracy: small scale, a need for rulers to depend on the people for knowledge, and finally the ability of members of society to exit to other locales if they were unhappy with a ruler. These three features were not always present in the same measure, but collectively they helped to underpin early democracy….(More)”

Citizen social science in practice: the case of the Empty Houses Project


Paper by Alexandra Albert: “The growth of citizen science and participatory science, where non-professional scientists voluntarily participate in scientific activities, raises questions around the ownership and interpretation of data, issues of data quality and reliability, and new kinds of data literacy. Citizen social science (CSS), as an approach that bridges these fields, calls into question the way in which research is undertaken, as well as who can collect data, what data can be collected, and what such data can be used for. This article outlines a case study—the Empty Houses Project—to explore how CSS plays out in practice, and to reflect on the opportunities and challenges it presents. The Empty Houses Project was set up to investigate how citizens could be mobilised to collect data about empty houses in their local area, so as to potentially contribute towards tackling a pressing policy issue. The study shows how the possibilities of CSS exceed the dominant view of it as a new means of creating data repositories. Rather, it considers how the data produced in CSS is an epistemology, and a politics, not just a realist tool for analysis….(More)”.

2030 Compass CoLab


About: “2030 Compass CoLab invites a group of experts, using an online platform, to contribute their perspectives on potential interactions between the goals in the UN’s 2030 Agenda for Sustainable Development.

By combining the insight of participants who posses broad and diverse knowledge, we hope to develop a richer understanding of how the Sustainable Development Goals (SDGs) may be complementary or conflicting.

Compass 2030 CoLab is part of a larger project, The Agenda 2030 Compass Methodology and toolbox for strategic decision making, funded by Vinnova, Sweden’s government agency for innovation.

Other elements of the larger project include:

  • Deliberations by a panel of experts who will convene in a series of live meetings to undertake in-depth analysis on interactions between the goals. 
  • Quanitative analysis of SDG indicators time series data, which will examine historical correlations between progress on the SDGs.
  • Development of a knowledge repository, residing in a new software tool under development as part of the project. This tool will be made available as a resource to guide the decisions of corporate executives, policy makers, and leaders of NGOs.

The overall project was inspired by the work of researchers at the Stockholm Environment Institute, described in Towards systemic and contextual priority setting for implementing the 2030 Agenda, a 2018 paper in Sustainability Science by Nina Weitz, Henrik Carlsen, Måns Nilsson, and Kristian Skånberg….(More)”.

“Civic tech” and “digital democracy” to “open up” democracy?


Clément Mabi in Réseaux: “This paper posits that digital participatory democracy can be seen as a new anchor of participatory governmentality. Conveniently called “digital democracy”, its implementation contributes to the spread of a particular conception of government through participation, influenced by digital literacy and its principles of self-organization and interactivity. By studying the deployment and trajectory of the so-called “civic tech” movement in France, the aim is to show that the project of democratic openness embodied by the movement has gradually narrowed down to a logic of services, for the purposes of institutions. The “great national debate” triggered a shift in this trajectory. While part of the community complied with the government’s request to facilitate participation, the debate also gave unprecedented visibility to critics who contributed to the emergence of a different view of the role of digital technologies in democracy….(More)“.

E-mail Is Making Us Miserable


Cal Newport at The New Yorker: “In early 2017, a French labor law went into effect that attempted to preserve the so-called right to disconnect. Companies with fifty or more employees were required to negotiate specific policies about the use of e-mail after work hours, with the goal of reducing the time that workers spent in their in-boxes during the evening or over the weekend. Myriam El Khomri, the minister of labor at the time, justified the new law, in part, as a necessary step to reduce burnout. The law is unwieldy, but it points toward a universal problem, one that’s become harder to avoid during the recent shift toward a more frenetic and improvisational approach to work: e-mail is making us miserable.

To study the effects of e-mail, a team led by researchers from the University of California, Irvine, hooked up forty office workers to wireless heart-rate monitors for around twelve days. They recorded the subjects’ heart-rate variability, a common technique for measuring mental stress. They also monitored the employees’ computer use, which allowed them to correlate e-mail checks with stress levels. What they found would not surprise the French. “The longer one spends on email in [a given] hour the higher is one’s stress for that hour,” the authors noted. In another study, researchers placed thermal cameras below each subject’s computer monitor, allowing them to measure the tell-tale “heat blooms” on a person’s face that indicate psychological distress. They discovered that batching in-box checks—a commonly suggested “solution” to improving one’s experience with e-mail—is not necessarily a panacea. For those people who scored highly in the trait of neuroticism, batching e-mails actually made them more stressed, perhaps because of worry about all of the urgent messages they were ignoring. The researchers also found that people answered e-mails more quickly when under stress but with less care—a text-analysis program called Linguistic Inquiry and Word Count revealed that these anxious e-mails were more likely to contain words that expressed anger. “While email use certainly saves people time effort in communicating, it also comes at a cost, the authors of the two studies concluded. Their recommendation? To “suggest that organizations make a concerted effort to cut down on email traffic.”

Other researchers have found similar connections between e-mail and unhappiness. A study, published in 2019, looked at long-term trends in the health of a group of nearly five thousand Swedish workers. They found that repeated exposure to “high information and communication technology demands” (translation: a need to be constantly connected) were associated with “suboptimal” health outcomes. This trend persisted even after they adjusted the statistics for potential complicating factors such as age, sex, socioeconomic status, health behavior, body-mass index, job strain, and social support. Of course, we don’t really need data to capture something that so many of us feel intuitively. I recently surveyed the readers of my blog about e-mail. “It’s slow and very frustrating. . . . I often feel like email is impersonal and a waste of time,” one respondent said. “I’m frazzled—just keeping up,” another admitted. Some went further. “I feel an almost uncontrollable need to stop what I’m doing to check email,” one person reported. “It makes me very depressed, anxious and frustrated.”…(More)”

Dialogues about Data: Building trust and unlocking the value of citizens’ health and care data


Nesta Report by Sinead Mac Manus and Alice Clay: “The last decade has seen exponential growth in the amount of data generated, collected and analysed to provide insights across all aspects of industry. Healthcare is no exception. We are increasingly seeing the value of using health and care data to prevent ill health, improve health outcomes for people and provide new insights into disease and treatments.

Bringing together common themes across the existing research, this report sets out two interlinked challenges to building a data-driven health and care system. This is interspersed with best practice examples of the potential of data to improve health and care, as well as cautionary tales of what can happen when this is done badly.

The first challenge we explore is how to increase citizens’ trust and transparency in data sharing. The second challenge is how to unlock the value of health and care data.

We are excited about the role for participatory futures – a set of techniques that systematically engage people to imagine and create more sustainable, inclusive futures – in helping governments and other organisations work with citizens to engage them in debate about their health and care data to build a data-driven health and care system for the benefit of all….(More)”.

How can stakeholder engagement and mini-publics better inform the use of data for pandemic response?


Andrew Zahuranec, Andrew Young and Stefaan G. Verhulst at the OECD Participo Blog Series:

“What does the public expect from data-driven responses to the COVID-19 pandemic? And under what conditions?” These are the motivating questions behind The Data Assembly, a recent initiative by The GovLab at New York University Tandon School of Engineering — an action research center that aims to help institutions work more openly, collaboratively, effectively, and legitimately.

Launched with support from The Henry Luce Foundation, The Data Assembly solicited diverse, actionable public input on data re-use for crisis response in the United States. In particular, we sought to engage the public on how to facilitate, if deemed acceptable, the use of data that was collected for a particular purpose for informing COVID-19. One additional objective was to inform the broader emergence of data collaboration— through formal and ad hoc arrangements between the public sector, civil society, and those in the private sector — by evaluating public expectation and concern with current institutional, contractual, and technical structures and instruments that may underpin these partnerships.

The Data Assembly used a new methodology that re-imagines how organisations can engage with society to better understand local expectations regarding data re-use and related issues. This work goes beyond soliciting input from just the “usual suspects”. Instead, data assemblies provide a forum for a much more diverse set of participants to share their insights and voice their concerns.

This article is informed by our experience piloting The Data Assembly in New York City in summer 2020. It provides an overview of The Data Assembly’s methodology and outcomes and describes major elements of the effort to support organisations working on similar issues in other cities, regions, and countries….(More)”.

The Power of Virtual Communities


Report by The GovLab: “When India went into lockdown in response to the COVID-19 pandemic, restrictions on movement affected people’s access to medicine, food and other supplies that they relied upon. HIV/AIDS sufferers feared traveling to clinics and labs to pick up their medication. Needing help, many turned to HumanKind Global, a new network of thousands of volunteers who coordinate aid through a Facebook Group and WhatsApp (also owned by Facebook).

Mahita Nagaraj, 39, a self-employed digital marketing professional and single mother based in Bangalore, created the group in March 2020. In just four weeks, HumanKind Global volunteers delivered lifesaving HIV medicines to more than 170 people across India. It has since grown to more than 50,000 members. Answering more than 25,000 requests for help, these volunteers have coordinated blood donations, delivered life-saving medication and provided people stranded at home with enough food to eat.

HumanKind Global is an online group, a form of human organization that is expanding at a remarkable scale and speed. Online groups exist for many reasons. Some offer lifesaving support while others enable people—whether they life next door or across an ocean—to trade articles, jokes, photographs, insults, ideas, advice, information, and sometimes misinformation. The space in which contemporary online groups are active is at once global and local, intimate and vast. A post can reach two million people, or spark a conversation between just two. Governed by their own members and the policies of the platforms on which they are hosted, these groups have diverse rules that seek to create a space in which their members can connect supported by feelings of belonging, intimacy and trust.

Online groups like HumanKind Global can be found on many platforms. There are discussion groups on Reddit, artist colonies on LEGO Mindstorms, player groups on gaming platforms like Twitch, or parenting groups in which members go online to organize real-life meetings through MeetUp. But in this report we study Facebook Groups, specifically, as one category of online group….(More)”. (See also: https://virtual-communities.thegovlab.org/)
