    "With each interaction, Alexa is training to hear better, to interpret more precisely, to trigger actions that map to the user's commands more accurately, and to build a more complete model of their preferences, habits and desires. What is required to make this possible? Put simply: each small moment of convenience - be it answering a question, turning on a light, or playing a song - requires a vast planetary network, fueled by the extraction of non-renewable materials, labor, and data. The scale of resources required is many magnitudes greater than the energy and labor it would take a human to operate a household appliance or flick a switch. A full accounting for these costs is almost impossible, but it is increasingly important that we grasp the scale and scope if we are to understand and govern the technical infrastructures that thread through our lives. III The Salar, the world's largest flat surface, is located in southwest Bolivia at an altitude of 3,656 meters above sea level. It is a high plateau, covered by a few meters of salt crust which are exceptionally rich in lithium, containing 50% to 70% of the world's lithium reserves. 4 The Salar, alongside the neighboring Atacama regions in Chile and Argentina, are major sites for lithium extraction. This soft, silvery metal is currently used to power mobile connected devices, as a crucial material used for the production of lithium-Ion batteries. It is known as 'grey gold.' Smartphone batteries, for example, usually have less than eight grams of this material. 5 Each Tesla car needs approximately seven kilograms of lithium for its battery pack. 6 All these batteries have a limited lifespan, and once consumed they are thrown away as waste. Amazon reminds users that they cannot open up and repair their Echo, because this will void the warranty. The Amazon Echo is wall-powered, and also has a mobile battery base. This also has a limited lifespan and then must be thrown away as waste. According to the Ay

Originally published at the Institute for New Economic Thinking website Across the globe, a collective freak-out spanning the whole political system is picking up steam with every new "surprise" election, rush of tormented souls across borders, and tweet from the star of America's great unreality show, Donald Trump. But what exactly is the force that seems to be pushing us towards Armageddon? Is it capitalism gone wild? Globalization? Political corruption? Techno-nightmares? Rajani Kanth, a political economist, social thinker, and poet, goes beyond any of these explanations for the answer. In his view, what's throwing most of us off kilter - whether we think of ourselves as on the left or right, capitalist or socialist -was birthed 400 years ago during the period of the Enlightenment. It's a set of assumptions, a particular way of looking at the world that pushed out previous modes o

Using a real-world network to model localized COVID-19 control strategies | Nature Medi... - 0 views

  •  
    Case isolation and contact tracing can contribute to the control of COVID-19 outbreaks1,2. However, it remains unclear how real-world social networks could influence the effectiveness and efficiency of such approaches. To address this issue, we simulated control strategies for SARS-CoV-2 transmission in a real-world social network generated from high-resolution GPS data that were gathered in the course of a citizen-science experiment3,4. We found that tracing the contacts of contacts reduced the size of simulated outbreaks more than tracing of only contacts, but this strategy also resulted in almost half of the local population being quarantined at a single point in time. Testing and releasing non-infectious individuals from quarantine led to increases in outbreak size, suggesting that contact tracing and quarantine might be most effective as a 'local lockdown' strategy when contact rates are high. Finally, we estimated that combining physical distancing with contact tracing could enable epidemic control while reducing the number of quarantined individuals. Our findings suggest that targeted tracing and quarantine strategies would be most efficient when combined with other control measures such as physical distancing.

Our Social Nature Makes Nearly Everything Contagious. - 0 views

  •  
    Human networks are not random. We connect to others who're like us in some way; social scientists call this homophily. A point of similarity might be something as fundamental to our identity as gender, religion, ethnicity, age, values, or beliefs. Or it could be, and often is, socioeconomic status. Or geographic-say, a neighborhood, city, or region where you grew up. Or an enthusiasm-football, a popular video game, or a breed of dog. When we meet someone at a party, we quickly try to find out if our networks connect in some way. Where are you from? What do you do? How do you know the host? Homophily is a human universal and an essential piece of our mental equipment for sustaining cooperation.

Geographical fragmentation of the global network of Twitter communications: Chaos: An I... - 0 views

  •  
    The introduction of the Internet rapidly enabled unprecedented global connectivity. In about two decades, communication became instantaneous, affordable, and independent of physical barriers. People, however, do not seem to be communicating with each other homogeneously. Online communication networks appear to be polarized and echo-chambers are manifesting for political1-5 and non-political6-9 reasons. Understanding the emergent structure of information flows on the Internet and its implications for the complexity of society is a challenge for scientists and technology developers. Mapping the organization of social systems is crucial for effective policy making involving ethnic groups10 as well as economic growth.11

Social Network Algorithms Are Distorting Reality By Boosting Conspiracy Theories | Co.E... - 0 views

  • Social platforms—in their effort to keep users continually engaged (and targeted with relevant ads)—are designed to surface what’s popular and trending, whether it’s true or not. Since nearly half of web-using adults now get their news from Facebook in any given week, what counts as "truth" on our social platforms matters. When nonsense stories gain traction, they’re extremely difficult to correct. And stories jump from platform to platform, reaching new audiences and "going viral" in ways and at speeds that were previously impossible.

Social Media's Globe-Shaking Power - The New York Times - 0 views

  • For people who like an orderly, predictable world, this is the scariest thing about Facebook; not that it may be full of lies (a problem that could potentially be fixed), but that its scope gives it real power to change history in bold, unpredictable ways.
  • One is the ubiquity of Facebook, which has reached a truly epic scale. Last month the company reported that about 1.8 billion people now log on to the service every month. Because social networks feed off the various permutations of interactions among people, they become strikingly more powerful as they grow. With about a quarter of the world’s population now on Facebook, the possibilities are staggering.
  • Thanks to the internet, now each person with once-maligned views can see that he’s not alone. And when these people find one another, they can do things — create memes, publications and entire online worlds that bolster their worldview, and then break into the mainstream.

    "Yale sociologist Emily Erikson, who also studies social networks but was not involved with the study, sees the new paper partly as a warning. "In some sense it's saying extreme voices can quickly take over public discourse," she says. "Perhaps if we're aware of that fact, we can guard against it.""

Falling through the gaps: insecure work and the social safety net | openDemocracy - 0 views

  • There is scope, in better delivery of work support, to challenge the atomisation and isolation of workers and the loss of social capital and networks of new working models. The precarity of insecure work needs to be addressed, rather than exacerbated, by the systems set up to support people through their working lives. In roles where working hours are flexible or unpredictable, the division between private and public lives can be complex. The interaction between the individual and the state needs to understand that complexity and support people to navigate through their working lives rather than leaving them without a compass or adequate map.
