Competitive Dynamics on Complex Networks | CaseWorthy

Competitive Dynamics on Complex Networks | CaseWorthy | Caseworthy | Scoop.it

We consider a dynamical network model in which two competitors have fixed and different states, and each normal agent adjusts its state according to a distributed consensus protocol. The state of each normal agent converges to a steady value which is a convex combination of the competitors' states, and is independent of the initial states of agents. This implies that the competition result is fully determined by the network structure and positions of competitors in the network.

A heatmap of war over water | CaseWorthy

A heatmap of war over water | CaseWorthy | Caseworthy | Scoop.it

As the climate shifts, rivers will both flood and dry up more often, according to the latest report from the Intergovernmental Panel on Climate Change. Shortages are especially likely in parts of the world already strapped for water, so political scientists expect feuds will become even more intense. To track disputes worldwide, researchers at Oregon State University spent a decade building a comprehensive database of international exchanges—-both conflicts and alliances—over shared water resources. They found that countries often begin disputes belligerently but ultimately reach peaceful agreements. Says Aaron Wolf, the geographer who leads the project, “For me the really interesting part is how even Arabs and Israelis, Indians and Pakistanis, are able to resolve their differences and find a solution.”

AleksBlumentals's insight:

The water stress is coming to a head as the worries of Methane release fro the Arctic mount. It is a all hands on deck moment we are in where there is precious little time considering the challenges.

Ursula K. Le Guin on Where Ideas Come From, the “Secret” of Great Writing, and the Trap of Marketing Your Work

Ursula K. Le Guin on Where Ideas Come From, the “Secret” of Great Writing, and the Trap of Marketing Your Work | Caseworthy | Scoop.it
I will dispose of the first myth as quickly as possible. The “secret” is skill. If you haven’t learned how to do something, the people who have may seem to be magicians, possessors of mysterious secrets. In a fairly simple art, such as making pie crust, there are certain teachable “secrets” of method that lead almost infallibly to good results; but in any complex art, such as housekeeping, piano-playing, clothes-making, or story-writing, there are so many techniques, skills, choices of method, so many variables, so many “secrets,” some teachable and some not, that you can learn them only by methodical, repeated, long-continued practice — in other words, by work.
AleksBlumentals's insight:

If we could jest get politicians and managers to accept that they aren't prepared or disposed to solving systemic issues that require alas the talents of a story teller!

Echoing Einstein’s idea of “combinatory play” and artist Francis Bacon’s notion that original art is the product of finely “grinding up” one’s influences, Le Guin speaks to the combinatorial nature of the creative process: "I would say that as a general rule, though an external event may trigger it, this inceptive state or story-beginning phase does not come from anywhere outside the mind that can be pointed to; it arises in the mind, from psychic contents that have become unavailable to the conscious mind, inner or outer experience that has been, in Gary Snyder’s lovely phrase, composted. I don’t believe that a writer “gets” (takes into the head) an “idea” (some sort of mental object) “from” somewhere, and then turns it into words and writes them on paper. At least in my experience, it doesn’t work that way. The stuff has to be transformed into oneself, it has to be composted, before it can grow a story."

Climate deal: the pistol has fired, so why aren’t we running? | Bill McKibben

Climate deal: the pistol has fired, so why aren’t we running? | Bill McKibben | Caseworthy | Scoop.it
The world’s fossil fuel companies still have five times the carbon we can burn and have any hope of meeting even the 2C target – and they’re still determined to burn it. The Koch Brothers will spend $900m on this year’s American elections. As we know from the ongoing Exxon scandal, there’s every reason to think that this industry will lie at every turn in an effort to hold on to their power – they’re clearly willing to break the planet if it means five or perhaps 10 more years of business as usual for them.
AleksBlumentals's insight:

So there’s no reason to go home from Paris complacent, or even all that optimistic. Left to its own devices, the world is still planning to spend the next decade or two mostly limbering up, engaging in the kind of impressive-looking stretching that runners enjoy at the start line. Meanwhile flood, drought, melt, and more of it all the time. In the past week we’ve seen people die in record rains from south India to the Lake District of Britain, from thePacific Northwest of America to the mountains of Norway.

Earth has lost a third of arable land in past 40 years, scientists say

Earth has lost a third of arable land in past 40 years, scientists say | Caseworthy | Scoop.it
The University of Sheffield’s Grantham Centre for Sustainable Futures, which undertook the study by analysing various pieces of research published over the past decade, said the loss was “catastrophic” and the trend close to being irretrievable without major changes to agricultural practices.
AleksBlumentals's insight:

“We are increasing the rate of loss and we are reducing soils to their bare mineral components,” he said. “We are creating soils that aren’t fit for anything except for holding a plant up. The soils are silting up river systems – if you look at the huge brown stain in the ocean where the Amazon deposits soil, you realise how much we are accelerating that process.

“We aren’t quite at the tipping point yet, but we need to do something about it. We are up against it if we are to reverse this decline.”

How the Western Diet Has Derailed Our Evolution - Issue 30: Identity - Nautilus

How the Western Diet Has Derailed Our Evolution - Issue 30: Identity - Nautilus | Caseworthy | Scoop.it
No one understands much about the dizzying variety documented so far—which microbes are good, which harmful, which irrelevant. One constant, though, is that people living subsistence lifestyles have tremendous diversity compared to westernized populations—up to 50 percent more species than North Americans or Europeans. That includes not only bacteria but eukaryotes—single-cell protists and large, multicellular worms. These organisms, which are often missing in the West, have historically been considered pathogens. But some evidence now suggests that they can favorably shape the microbiome, benefiting the host.
AleksBlumentals's insight:

Fiber is so important that scientists have given it a new designation: microbiota-accessible carbohydrates, or MACs. They think that the mismatch between the Westernized, MAC-starved microbiome and the human genome may predispose to Western diseases. (sorry, can't fix it with BigMacs BEWARE no fiber there)

This new biosensor can detect water contamination as it happens | Caseworthy | Scoop.it
Right now, detecting contaminated water can take days, and that puts humans and animals at serious risk. But a new biosensor developed by grad students in Denmark promises to spot unclean water in an instant, and whether it's used in a village well...
AleksBlumentals's insight:

Sensors can be placed throughout a particular network to detect problems at any particular point, and of course, there's no need to stop the flow of water to take samples - everything happens in real-time. You can think of it working in the same way as a smart sensor in a home, where conditions are continually monitored and an alert can be generated as soon as something doesn't look right.

Pretty simple.” And the more complex the defenses, the more potential for holes—and for complacent defenders, who often stop expecting the worst. “Say I infect your personal computer, use a form grabber, and get your username and password,” Beddoes continues. “Then I can bounce through your web browser onto their system. Then, if I get a virus on your phone as well, even a one-time password, I can use it to verify my identity”—thwarting two-step verification, the latest security layer. “You have to fiddle around more,” he says, “but once you’re in, you’re in.”

Martín von Hildebrand: An audacious plan for the Amazon

Martín von Hildebrand: An audacious plan for the Amazon | Caseworthy | Scoop.it
I would say the Western world sees a separation from nature and the human being, and nature is there for us to use and exploit. Most indigenous cultures believe they are part of nature, that they come from nature, and that they have to take care of the whole, which is nature, if they [are] to survive. They are much clearer in their relationship as part of nature.
AleksBlumentals's insight:

"...In the Western world, we’ve been living for the last 100 years or more in towns and in boxes of cement. We have separated from nature. Therefore, we’ve lost our intimacy. But it’s there under our skin; it is alive."

What is the most important lesson you’ve learned from the indigenous communities you’ve worked with? 

"I’d say what I’ve learned is that all of us have evolved for so long as part of nature and we developed an intimate relationship. Not only a knowledgeable relationship with the environment, but an intimate, sensual, skin-deep feeling as part of nature."

Why don't climate summits work?

Why don't climate summits work? | Caseworthy | Scoop.it
Climate summits are stuck in a box. The sides of the box are people’s habits of constraining the dialogue to enable the collective ‘solution delusion’. Yet ironically if these constraints were simply removed then vastly more effective solutions would become visible and possible. The first two sides are about choosing physical variables to focus on. The next two sides are about defining a climate solution. The final two sides are about what to actually do to create change at the necessary scale and speed. The six sides can together be use as ‘programming settings’ to switch climate talks from persistent failure to the potential for genuine progress.

But for the deal to mean anything, they said, the celebratory moment must give way immediately to an era in which intensive efforts are made to squeeze emissions out of the world economy.

The benefits to this are twofold. As Meyer told me, “Cars may have the potential to become much lighter and much tougher. You can imagine that could be very useful in a car, if you’re in a collision you want a lot of energy to be absorbed, but you also want the car to stay as light as possible, to be the most fuel efficient possible.” And fiber-reinforced plastics aren’t just used in car parts—they’re also used in aerospace engineering, construction, and armor like bulletproof vests.
