Lacking Brains, Plants Can Still Make Good Judgments About Risks - The New York Times - 0 views

  • Plants may not be getting enough credit. Not only do they remember when you touch them, it turns out that they can make risky decisions that are as sophisticated as those made by humans, all without brains or complex nervous systems. And they may even judge risks more efficiently than we do.
  • Researchers showed that when faced with the choice between a pot containing constant levels of nutrients or one with unpredictable levels, a plant will pick the mystery pot when conditions are sufficiently poor.
  • When nutrient levels were low, the plants laid more roots in the unpredictable pot. But when nutrients were abundant, they chose the one that always had the same amount. The plants somehow knew the best time to take risks.

  • “In bad conditions, the only chance of success is to take a chance and hope it works out, and that’s what the plants are doing,
  • This complex behavior in a plant supports an idea, known as risk sensitivity theory, that scientists have long had trouble testing in insects and animals. It states that when choosing between stable and uncertain outcomes, an organism will play it safe when things are going well, and take risks when times are hard.
  • The simplicity of plants makes it much easier to create a proper test for at least one reason: Plants don’t worry about feelings.

Don't Waste Your Emotions on Plants, They Have No Feelings | Live Science - 0 views

  • Trees — and all plants, for that matter — feel nothing at all, because consciousness, emotions and cognition are hallmarks of animals alone, scientists recently reported in an opinion article.
  • Though plants lack brains, the firing of electrical signals in their stems and leaves nonetheless triggered responses that hinted at consciousness, researchers previously reported.
  • Beginning in 2006, some scientists have argued that plants possess neuron-like cells that interact with hormones and neurotransmitters, forming "a plant nervous system, analogous to that in animals

New Life for Steel Plant Perks Up Depressed Illinois Town, Workforce - WSJ - 0 views

  • GRANITE CITY, Ill.—Ever since the layoffs a few years ago, many residents here had wondered when the local steel plant would again fire up its furnaces—or close forever.
  • Not only were hundreds of steelworkers left jobless when United States Steel Corp. X -1.49% scaled down its operations in Granite City, Ill., in 2015, but lunch deliveries to the plant vanished for a local diner while a shoe store’s work-boot sales plummeted. At least 26 businesses closed within a year, according to an area chamber of commerce.
  • The Granite City steel plant didn’t entirely close. Before the layoffs started, the plant employed 2,200, making it the town’s biggest employer, according to a securities filing. After layoffs of approximately 1,500 employees, some were eventually brought back, but the furnaces remained off.

Nature Has A Formula That Tells Us When It's Time To Die : Krulwich Wonders... : NPR - 1 views

  • Every living thing is a pulse. We quicken, then we fade. There is a deep beauty in this, but deeper down, inside every plant, every leaf, inside every living thing (us included) sits a secret.
  • Everything alive will eventually die, we know that, but now we can read the pattern and see death coming. We have recently learned its logic, which "You can put into mathematics," says physicist Geoffrey West. It shows up with "extraordinary regularity," not just in plants, but in all animals, from slugs to giraffes. Death, it seems, is intimately related to size.
  • Life is short for small creatures, longer in big ones.
  • ...5 more annotations...
  • A 2007 paper checked 700 different kinds of plants, and almost every time they applied the formula, it correctly predicted lifespan. "This is universal. It cuts across the design of organisms," West says. "It applies to me, all mammals, and the trees sitting out there, even though we're completely different designs."
  • The formula is a simple quarter-power exercise: You take the mass of a plant or an animal, and its metabolic rate is equal to its mass taken to the three-fourths power.
  • It's hard to believe that creatures as different as jellyfish and cheetahs, daisies and bats, are governed by the same mathematical logic, but size seems to predict lifespan.
  • It tells animals for example, that there's a universal limit to life, that though they come in different sizes, they have roughly a billion and a half heart beats; elephant hearts beat slowly, hummingbird hearts beat fast, but when your count is up, you are over.
  • In any big creature, animal or plant, there are so many more pathways, moving parts, so much more work to do, the big guys could wear out very quickly. So Geoffrey West and his colleagues found that nature gives larger creatures a gift: more efficient cells. Literally.

Climate change: 1 in 3 plant and animal species extinct in 50 years, study warns - CNN - 0 views

shared by tongoscar on 22 Feb 20 - No Cached
  • Take a moment to cherish your plants and appreciate the animals you see around you.In 50 years, a third of them may no longer exist.
  • approximately one in three plant, insect and animal species could face extinction by 2070. However, things could be even worse if emissions continue to rise as rapidly as they have in recent decades.
  • In a worst-case scenario, that number could rise to over 55%.
  • ...7 more annotations...
  • Of the 538 species studied, 44% of them have already experienced an extinction in a particular local area.
  • While many species were able to tolerate a moderate increase in maximum temperatures, 50% of the species had local extinctions if maximum temperatures increased by more than 0.5 degrees Celsius. That number rose to 95% if temperatures increased by more than 2.9 degrees Celsius.
  • With January going in the record books as the warmest January in 141 years and statistical analysis done by NOAA scientists predicting 2020 to be one of the five warmest years on record, the researchers believe there will be more local extinctions across the globe.
  • The Paris Agreement was signed in 2015 by ministers from 195 countries from around the globe.It committed these countries to keep global warming below 2 degrees Celsius above pre-industrial levels and below 1.5 degrees, if possible.
  • "Based on our sample of 538 species, we projected a loss of 30% of the species under a more extreme warming scenario, but only about 16% if we stick to the Paris Agreement," Wiens told CNN. "So, think in 1 in 6 species, not 1 in 3."
  • The Paris Agreement is an international pact aimed at curbing global emissions of heat-trapping gases.Unfortunately, studies have shown that so far, many countries are failing to meet the emissions cuts they set to limit climate change.
  • "Some researchers have estimated that two-thirds of all species of plants and animals could be lost due to tropical deforestation alone," Wiens said. "If you combine that with climate change (which can impact species in protected forests and other reserves), then it really is terrible. Even from our data alone, there are extreme warming scenarios where 55% of the species would be lost from intact habitats. And note that deforestation also increases global warming. It is a double whammy against biodiversity."

The Perseverance of New York City's Wildflowers - The New York Times - 0 views

  • The Perseverance of New York City’s Wildflowers
  • A park in Williamsburg awaits the miniature beauty of its spring blossoms.
  • In Williamsburg, on a seven-acre park by the East River, spring will soon unfurl in blue blossoms
  • ...21 more annotations...
  • Cornflowers are always the first to bloom in the pollinator meadow of Marsha P. Johnson State Park, a welcome sign to bees and people that things are beginning to thaw.
  • If New York City has a warm spring, the cornflowers may open up by late April, eventually followed by orange frills of butterfly milkweed, purple spindly bee balm and yolk-yellow, black-eyed Susans that also inhabit the meadow — hardy species that can weather the salty spray that confronts life on the waterfront.
  • Not all of these flowers are native to New York, or even North America, but they have sustained themselves long enough to become naturalized
  • These species pose little threat to native wildlife, unlike more domineering introduced species such as mugwort, an herb with an intrepid rhizome system.
  • A wildflower can refer to any flowering plant that was not cultivated, intentionally planted or given human aid, yet it still managed to grow and bloom.
  • This is one of several definitions offered by the plant ecologist Donald J. Leopold in Andrew Garn’s new photo book “Wildflowers of New York City,” and one that feels particularly suited to the city and its many transplants.
  • Scarlet bee balm.
  • Ms. Lopez, who grew up on the Upper West Side near a sooty smokestack, has always longed for more green spaces in the city.
  • In February of 2020, Gov. Andrew Cuomo renamed the park after the activist Marsha P. Johnson, one of the central figures of the Stonewall riots and a co-founder of Street Transvestite Action Revolutionaries with the activist Sylvia Rivera. Ms. Johnson, who died in 1992 of undetermined causes, would have turned 75 in August 2020.
  • Mr. Garn did not intend for “Wildflowers of New York City” to be a traditional field guide for identifying flowers. Rather, his reverent portraits invite us to delight in the beauty of flowers that we more often encounter in a sidewalk crack than in a bouquet.
  • Marsha P. Johnson, a central figure of the Stonewall riots and a co-founder of Street Transvestite Action Revolutionaries
  • Ms. Johnson was known for wearing crowns of fresh flowers that she would arrange from leftover blooms and discarded daffodils from the flower district in Manhattan, where she often slept.
  • In one photo, Ms. Johnson wears a crown of roses, carnations, chrysanthemums, frilly tulips, statice and baby’s breath.
  • Although cumulous clusters of baby’s breath are now a staple of floral arrangements, the species is a wildflower native to central and Eastern Europe.
  • Ms. Lopez and STARR have criticized a proposal for a new $70 million beach scheduled to be built on Gansevoort Peninsula, near waterfronts where Ms. Rivera once lived and Ms. Johnson died. In its place, she suggests a memorial garden for Ms. Johnson, Ms. Rivera and other transgender people
  • “We will never feed enough people, we will never plant enough flowers, never be good enough to honor Sylvia and Marsha,” Ms. Lopez said. “They cared too much, even when no one cared for them.”
  • “I have candles lit always for Marsha and Sylvia, but I’m praying especially hard now that we get a plan that includes lots of flowers,” said Mariah Lopez, the executive director of Strategic Trans Alliance for Radical Reform, or STARR, an advocacy group.
  • Her dream of the park includes a range of verdant and functional spaces: a paved area where people can vogue and hold rallies, a flower garden in tribute to Ms. Johnson, a greenhouse and an apiary for bees.
  • Tansy.
  • The redesign of the park will add a new fence around the meadow, as well as interpretive signs about the pollinators who depend on its wildflowers. “What would happen if there were no bees in the world?”
  • “We have to protect them. That’s what the function of this sweet little meadow is.”

Biomimicry in Reverse: 5 Inventions That Help Animals Survive Humans | Big Think - 0 views

  •  
    This article reminded me of an article I read in my SAT reading section. Biomimicry is a very interesting subject because it learns from the nature. An example I have read about is the arrangement of the solar plants. Scientists arrange them like how seeds arranged in a sunflower to maximize the amount of solar energy absorbed. And now, scientists are using human technology to benefit nature. But somehow I think it is inefficient because if we have to spend money to make the environment we influenced to feel like natural, why don't we protect it and keep it natural at the first place? --Sissi (3/2/2017)

Biofuel Mimicry | The Scientist Magazine® - 0 views

  • ants create the largest colonies of any ant, with some comprising 8 million individuals. To sustain themselves, they march across the forest carrying vast quantities of leaves, piece by piece, in great green convoys, back to the nest.

  • identification of enzymes capable of degrading lignocelluloses could also be a boon for the biofuels industry. Biofuel companies already use enzyme blends to break down starches from plant biomass, most commonly corn, into sugars to be fermented into ethanol. But the enzymes currently available can’t break down tough-to-degrade molecules such as lignocelluloses on an industrial scale.
  • idea is that the genes coding for these enzymes in the fungus gardens of leafcutter ants can be mass-produced in the lab by inserting them into E. coli or yeast, then used to break down feedstocks that require less land, fewer resources, and that don’t compete with food crops. “This is a highly evolved system, so the hypothesis is that the enzymes would be highly tuned to break down plant biomass,”
  • researchers will also need to take into account the role of bacteria. “It could be that bacteria are producing some enzymes that enhance the efficacy of the fungal enzymes,” says Aylward. “Integrating the bacterial component is likely to be important, because the synergism we see with leafcutter gardens is on the level of the entire symbiosis.”

Here's what the government's dietary guidelines should really say - The Washington Post - 0 views

  • If I were writing the dietary guidelines, I would give them a radical overhaul. I’d go so far as to radically overhaul the way we evaluate diet. Here’s why and how.
  • Lately, as scientists try, and fail, to reproduce results, all of science is taking a hard look at funding biases, statistical shenanigans and groupthink. All that criticism, and then some, applies to nutrition.
  • Prominent in the charge to change the way we do science is John Ioannidis, professor of health research and policy at Stanford University. In 2005, he published “Why Most Research Findings Are False” in the journal PLOS Medicin
  • ...15 more annotations...
  • He came down hard on nutrition in a pull-no-punches 2013 British Medical Journal editorial titled, “Implausible results in human nutrition research,” in which he noted, “Almost every single nutrient imaginable has peer reviewed publications associating it with almost any outcome.”
  • Ioannidis told me that sussing out the connection between diet and health — nutritional epidemiology — is enormously challenging, and “the tools that we’re throwing at the problem are not commensurate with the complexity and difficulty of the problem.” The biggest of those tools is observational research, in which we collect data on what people eat, and track what happens to them.
  • He lists plant-based foods — fruit, veg, whole grains, legumes — but acknowledges that we don’t understand enough to prescribe specific combinations or numbers of servings.
  • funding bias isn’t the only kind. “Fanatical opinions abound in nutrition,” Ioannidis wrote in 2013, and those have bias power too.
  • “Definitive solutions won’t come from another million observational papers or small randomized trials,” reads the subtitle of Ioannidis’s paper. His is a burn-down-the-house ethos.
  • When it comes to actual dietary recommendations, the disagreement is stark. “Ioannidis and others say we have no clue, the science is so bad that we don’t know anything,” Hu told me. “I think that’s completely bogus. We know a lot about the basic elements of a healthy diet.”
  • Give tens of thousands of people that FFQ, and you end up with a ginormous repository of possible correlations. You can zero in on a vitamin, macronutrient or food, and go to town. But not only are you starting with flawed data, you’ve got a zillion possible confounding variables — dietary, demographic, socioeconomic. I’ve heard statisticians call it “noise mining,” and Ioannidis is equally skeptical. “With this type of data, you can get any result you want,” he said. “You can align it to your beliefs.”
  • Big differences in what people eat track with other differences. Heavy plant-eaters are different from, say, heavy meat-eaters in all kinds of ways (income, education, physical activity, BMI). Red meat consumption correlates with increased risk of dying in an accident as much as dying from heart disease. The amount of faith we put in observational studies is a judgment call.
  • I find myself in Ioannidis’s camp. What have we learned, unequivocally enough to build a consensus in the nutrition community, about how diet affects health? Well, trans-fats are bad.
  • Over and over, large population studies get sliced and diced, and it’s all but impossible to figure out what’s signal and what’s noise. Researchers try to do that with controlled trials to test the connections, but those have issues too. They’re expensive, so they’re usually small and short-term. People have trouble sticking to the diet being studied. And scientists are generally looking for what they call “surrogate endpoints,” like increased cholesterol rather than death from heart disease, since it’s impractical to keep a trial going until people die.
  • , what do we do? Hu and Ioannidis actually have similar suggestions. For starters, they both think we should be looking at dietary patterns rather than single foods or nutrients. They also both want to look across the data sets. Ioannidis emphasizes transparency. He wants to open data to the world and analyze all the data sets in the same way to see if “any signals survive.” Hu is more cautious (partly to safeguard confidentiality
  • I have a suggestion. Let’s give up on evidence-based eating. It’s given us nothing but trouble and strife. Our tools can’t find any but the most obvious links between food and health, and we’ve found those already.
  • Instead, let’s acknowledge the uncertainty and eat to hedge against what we don’t know
  • We’ve got two excellent hedges: variety and foods with nutrients intact (which describes such diets as the Mediterranean, touted by researchers). If you severely limit your foods (vegan, keto), you might miss out on something. Ditto if you eat foods with little nutritional value (sugar, refined grains). Oh, and pay attention to the two things we can say with certainty: Keep your weight down, and exercise.
  • I used to say I could tell you everything important about diet in 60 seconds. Over the years, my spiel got shorter and shorter as truisms fell by the wayside, and my confidence waned in a field where we know less, rather than more, over time. I’m down to five seconds now: Eat a wide variety of foods with their nutrients intact, keep your weight down and get some exercise.

The quiet loss of knowledge threatens indigenous communities -- ScienceDaily - 0 views

  • Plants play an important role for most indigenous communities in South America, and not merely as a source of food. They also provide the raw material for building materials, tools, medicine, and much more. The extinction of a plant species therefore also endangers the very foundation of these people's way of life. advertisement
  • The problem is that this is not written down. Passed down as a cultural inheritance, it exists only in the minds of the people -- and could therefore vanish almost unnoticed. "Very little is known about how vulnerable this knowledge is in the context of current global change," says Jordi Bascompte, professor of ecology at the University of Zurich.
  • "There is therefore an urgent need to find out how biological and cultural factors interact with each other in determining the services provided by biodiversity.."
  • ...4 more annotations...
  • For their study, they analyzed knowledge held by 57 indigenous communities in the Amazon basin, the Andes and the Chocó region to collate their knowledge of palm trees. The researchers then depicted the different palm species and their uses in graphical form in a network, from which they could identify the local and regional links between the knowledge of indigenous communities.
  • "In this context, cultural diversity is just as important as biological diversity," says Jordi Bascompte. "In particular, the simultaneous loss of plant species and cultural inheritance leads to a much faster disintegration of the indigenous knowledge network."
  • However, the irreplaceable knowledge that is gradually disappearing from indigenous communities is equally important for the service that an ecosystem provides."
  • The study also highlights the value of transdisciplinary collaboration between ecology and social science: "The relationship established between biological and cultural diversity can help strengthen the resilience of indigenous communities in the face of global change."

  • Hodgson approached the organisers of the California State Fair wine competition, the oldest contest of its kind in North America, and proposed an experiment for their annual June tasting sessions.Each panel of four judges would be presented with their usual "flight" of samples to sniff, sip and slurp. But some wines would be presented to the panel three times, poured from the same bottle each time. The results would be compiled and analysed to see whether wine testing really is scientific.
  • Results from the first four years of the experiment, published in the Journal of Wine Economics, showed a typical judge's scores varied by plus or minus four points over the three blind tastings. A wine deemed to be a good 90 would be rated as an acceptable 86 by the same judge minutes later and then an excellent 94.
  • ...9 more annotations...
  • Hodgson's findings have stunned the wine industry. Over the years he has shown again and again that even trained, professional palates are terrible at judging wine."The results are disturbing," says Hodgson from the Fieldbrook Winery in Humboldt County, described by its owner as a rural paradise. "Only about 10% of judges are consistent and those judges who were consistent one year were ordinary the next year."Chance has a great deal to do with the awards that wines win."
  • French academic Frédéric Brochet tested the effect of labels in 2001. He presented the same Bordeaux superior wine to 57 volunteers a week apart and in two different bottles – one for a table wine, the other for a grand cru.The tasters were fooled.When tasting a supposedly superior wine, their language was more positive – describing it as complex, balanced, long and woody. When the same wine was presented as plonk, the critics were more likely to use negatives such as weak, light and flat.
  • In 2011 Professor Richard Wiseman, a psychologist (and former professional magician) at Hertfordshire University invited 578 people to comment on a range of red and white wines, varying from £3.49 for a claret to £30 for champagne, and tasted blind.People could tell the difference between wines under £5 and those above £10 only 53% of the time for whites and only 47% of the time for reds. Overall they would have been just as a successful flipping a coin to guess.
  • why are ordinary drinkers and the experts so poor at tasting blind? Part of the answer lies in the sheer complexity of wine.For a drink made by fermenting fruit juice, wine is a remarkably sophisticated chemical cocktail. Dr Bryce Rankine, an Australian wine scientist, identified 27 distinct organic acids in wine, 23 varieties of alcohol in addition to the common ethanol, more than 80 esters and aldehydes, 16 sugars, plus a long list of assorted vitamins and minerals that wouldn't look out of place on the ingredients list of a cereal pack. There are even harmless traces of lead and arsenic that come from the soil.
  • "People underestimate how clever the olfactory system is at detecting aromas and our brain is at interpreting them," says Hutchinson."The olfactory system has the complexity in terms of its protein receptors to detect all the different aromas, but the brain response isn't always up to it. But I'm a believer that everyone has the same equipment and it comes down to learning how to interpret it." Within eight tastings, most people can learn to detect and name a reasonable range of aromas in wine
  • People struggle with assessing wine because the brain's interpretation of aroma and bouquet is based on far more than the chemicals found in the drink. Temperature plays a big part. Volatiles in wine are more active when wine is warmer. Serve a New World chardonnay too cold and you'll only taste the overpowering oak. Serve a red too warm and the heady boozy qualities will be overpowering.
  • Colour affects our perceptions too. In 2001 Frédérick Brochet of the University of Bordeaux asked 54 wine experts to test two glasses of wine – one red, one white. Using the typical language of tasters, the panel described the red as "jammy' and commented on its crushed red fruit.The critics failed to spot that both wines were from the same bottle. The only difference was that one had been coloured red with a flavourless dye
  • Other environmental factors play a role. A judge's palate is affected by what she or he had earlier, the time of day, their tiredness, their health – even the weather.
  • Robert Hodgson is determined to improve the quality of judging. He has developed a test that will determine whether a judge's assessment of a blind-tasted glass in a medal competition is better than chance. The research will be presented at a conference in Cape Town this year. But the early findings are not promising."So far I've yet to find someone who passes," he says.

Super Mario Run's Not-So-Super Gender Politics - The New York Times - 0 views

  • Super Mario Run begins, as does almost every Super Mario title, with Princess Peach becoming a hostage who must be rescued by Mario. Just before her ritual kidnapping, Peach invites Mario to her castle and pledges to bake him a cake. Upon her rescue, she kisses Mario. The game also includes a second female character, Toadette, whose job is to wave a flag before and after a race, like a character from “Grease.”
  • But Super Mario Run relegates its female characters to positions of near helplessness. Peach and Toadette become playable only after you complete certain tasks, which makes the women in the game feel like prizes.
  • Still, lots of girls and women play video games. There are more women over 30 who play video games than boys under 18 who play, according to the industry’s lobbying arm, the Entertainment Software Association. A Pew Research Center survey published last year found that almost 60 percent of girls between the ages of 13 and 17 are gamers.

  • The knowledge that video games possess this power, that they allow us to adopt new identities and grant us new ways of seeing ourselves, is as old as Mario’s quest for his princess.

    The gender stereotype is everywhere, even in the most popular games. I am astonished that I become so numb about this kind of story. I have just played this game recently and I didn't feel anything weird or strange. It shows how deep this kind of stereotype is planted in my brain. I subconsciously put this kind of story into the category of normal. What we feel is common or right might not be correct in another person's perspective. It is always mind-blowing to see that how unusually or inappropriate something I think is normal can be. --Sissi (12/22/2016)

  • psychologist Elizabeth Loftus of the University of California–Irvine, has made her name working on false memory. She tells Alison George how recollections can be conjured up,
  • What exactly is going on when we retrieve a memory? EL: When we remember something, we're taking bits and pieces of experience—sometimes from different times and places—and bringing it all together to construct what might feel like a recollection but is actually a construction. The process of calling it into conscious awareness can change it, and now you're storing something that's different
  • The memory of witnesses to crimes and accidents was a natural place to go. In particular I looked at what happens when people are questioned about their experiences. I would ultimately see those questions as a means by which the memories got contaminated.
  • ...5 more annotations...
  • Depending on the study, you might get as many as 50 percent of people falling for the suggestion and developing a complete or partial false memory.
  • Is it the power of suggestion from a therapist that creates these "memories," then? EL: Yes, a lot of the cases involve suggestive psychotherapy. But you don't absolutely need the therapy. You can get suggestion from the culture and the environment, like when somebody turns on Oprah and sees one of these repressed-memory therapists talking, then believes this has happened to them.
  • How do you plant these memories? EL: We use a "false feedback" technique. We gather a whole bunch of data from you, about your personality, thoughts about different foods, all kinds of things. Later, we hand you this computerized profile, which reveals certain things that probably happened when you were a child. In the middle of the list is, say, that you got sick eating strawberry ice cream. We give you false feedback about your data, and then encourage you to elaborate and imagine. Later we ascertain whether you have a belief that it happened to you. Then we offer you a choice from all these different foods. In that example we found that participants didn't want strawberry ice cream as much.
  • bad governments, bad people, they don't have requirements of conduct. When we recently published a study about planting false memories among U.S. soldiers, I was worried we were putting out a recipe for how you can do horrible things to somebody and then wipe their memory away.
  • Is there any way to distinguish a false memory from a real one? EL: Without independent corroboration, little can be done to tell a false memory from a true one.

This Sociological Theory Explains Why Wall Street Is Rigged for Crisis - Bill Davidow -... - 0 views

  • near brush with nuclear catastrophe, brought on by a single foraging bear, is an example of what sociologist Charles Perrow calls a “normal accident.” These frightening incidents are “normal” not because they happen often, but because they are almost certain to occur in any tightly connected complex system.
  • Perrow had a fairly simple solution for the problem. High-risk systems, such as nuclear power plants, should be built only as a last resort.
  • errow stresses the role that human error and mismanagement play in these scenarios. The important lesson: failures in complex systems are caused not only by the hardware and software problems but by people and their motivations.
  • ...4 more annotations...
  • Normal accidents, like these, occur because two or more independent failures happen and interact in unpredictable ways. After studying calamities such as the Three Mile Island meltdown, explosions at chemical plants, and ships colliding in the open sea, Perrow observed that safety mechanisms put in place to make the systems safer in fact frequently trigger the final failure.
  • That solution won’t work for financial markets. We need currency hedges, futures markets, and derivatives to keep our economic systems functioning. But we also have to realize tweaking the current system will not fix the problem. Most of the supposedly strong cures implemented by legislators to date, such as prohibiting bank holding companies from proprietary trading, are inadequate as well.
  • how do we make our markets less danger prone? A good place to start would be to reduce the excessive trading volumes that lie at the root of accidents like the Flash Freeze, Flash Cash, and Goldman debacle. There is no valid reason for high frequency trading to make up more than 50 percent of all stock trades, and there is no pressing need for some $4 trillion in daily foreign currency transactions. A Tobin tax on transactions, first suggested by Noble laureate James Tobin in 1972, of as little as 0.1 percent, would significantly reduce these volumes. Smaller transaction volumes would reduce the size of accidents and possibly their frequency.
  • But tinkering with the current system and looking for easy ways out, as we are now, is bound to fail. We’re in danger of letting normal accidents in the financial system become all too normal.

Naturally Nonsense « The Dish - 1 views

  • it’s time to kill this mistaken idea once and for all. Basically everything in modern agriculture is unnatural. “The cereal crops we eat bear little resemblance to their naturally selected ancestors, and the environments in which we grow them are equally highly manipulated and engineered by us,” she writes. “We have, over the last 10,000 years, bred out of our main food plants all kinds of survival strategies that natural selection put in.”
  • “Agriculture is the invention of humans,” she adds. “It is the deliberate manipulation of plants (and animals) and the environment in which they grow to provide food for us. The imperative is not that we should stop interfering with nature, but that we should interfere in the best way possible to provide a reliable, sustainable, equitable supply of nutritious food.”

How Many of Your Memories Are Fake? - The Atlantic - 3 views

  • Special K for breakfast. Liverwurst and cheese for lunch. And I remember the song ‘You've Got Personality’ was playing as on the radio as I pulled up for work,” said Healy, one of 50 confirmed people in the United States with Highly Superior Autobiographical Memory, an uncanny ability to remember dates and events.
  • New research released this week has found that even people with phenomenal memory are susceptible to having “false memories,” suggesting that “memory distortions are basic and widespread in humans, and it may be unlikely that anyone is immune,” according to the authors of the study published in Proceedings of the National Academy of Sciences (PNAS).
  • Professor Elizabeth Loftus, who has spent decades researching how memories can become contaminated with people remembering—sometimes quite vividly and confidently—events that never happened. Loftus has found that memories can be planted in someone’s mind if they are exposed to misinformation after an event, or if they are asked suggestive questions about the past

  • Loftus’s research has already rattled our justice system, which relies so heavily on eyewitness testimonies.
  • “It’s so powerful when somebody tells you something and they have a lot of detail,” Loftus said. “Especially when they express emotion. To just say, ‘Oh my god it must be true.’ But all those characteristics are also true of false memories, particularly the heavily rehearsed ones that you ruminate over. They can be very detailed. You can be confident. You can be emotional. So you need independent corroboration.”
  • When later asked about the events, the superior memory subjects indicated the erroneous facts as truth at about the same rate as people with normal memory.
  • been able to successfully convince ordinary people that they were lost in a mall in their childhood, pointed out that false memory recollections also occur among high profile people.
  • All memory, as McGaugh explained, is colored with bits of life experiences. When people recall, “they are reconstructing,” he said. “It doesn't mean it’s totally false. It means that they’re telling a story about themselves and they’re integrating things they really do remember in detail, with things that are generally true.”
  • “puzzling why (Highly Superior Autobiographical Memory) individuals remember some trivial details, such as what they had for lunch 10 years ago, but not others, such as words on a word list or photographs in a slideshow,” Patihis and colleagues noted in the PNAS study. “The answer to this may be that they may extract some personally relevant meaning from only some trivial details and weave them into the narrative for a given day.”
  • For all of us, the stronger the emotion attached to a moment, the more likely those parts of our brains involved in memory will become activated.
  • “Why did evolution do that?” McGaugh said. “Because it was essential for our survival.
  • We now know animals are likely susceptible to memory distortions too, as MIT researchers recently were able to successfully plant false memories in mice.
  • “We’re all creating stories. Our lives are stories in that sense.”
  • “but you as the writer have the obligation to get as close to the truth as you possibly can,” Meyer said
  • The mind and its memory do not just record and retrieve information and experiences, but also infer, fill in gaps, and construct, wrote Bryan Boyd wrote in On the Origin of Stories. “Episodic memory’s failure to provide exact replicas of experiences appears to not be a limitation of memory but an adaptive design.”

    This is an interesting article about the fallacy of memory, and our perceptions of our memory.

It's Consumer Spending, Stupid - NYTimes.com - 0 views

  • using business profits to increase productivity and output — doesn’t actually drive economic growth. Consumer debt and government spending do. Private investment isn’t even necessary to promote growth.
  • Economists will tell you that private business investment causes growth because it pays for the new plant or equipment that creates jobs, improves labor productivity and increases workers’ incomes. As a result, you’ll hear politicians insisting that more incentives for private investors — lower taxes on corporate profits — will lead to faster and better-balanced growth.
  • But history shows that this is wrong.
  • ...7 more annotations...
  • President George W. Bush’s tax cuts had similar effects between 2001 and 2007: real growth in the absence of new investment.
  • over the course of the last century, net business investment atrophied while G.D.P. per capita increased spectacularly. And the source of that growth? Increased consumer spending, coupled with and amplified by government outlays.
  • Between 1900 and 2000, real gross domestic product per capita (the output of goods and services per person) grew more than 600 percent. Meanwhile, net business investment declined 70 percent as a share of G.D.P. What’s more, in 1900 almost all investment came from the private sector — from companies, not from government — whereas in 2000, most investment was either from government spending (out of tax revenues) or “residential investment,” which means consumer spending on housing, rather than business expenditure on plants, equipment and labor.
  • According to the Organization for Economic Cooperation and Development, retained corporate earnings that remain uninvested are now close to 8 percent of G.D.P., a staggering sum in view of the unemployment crisis we face.
  • So corporate profits do not drive economic growth — they’re just restless sums of surplus capital, ready to flood speculative markets at home and abroad. In the 1920s, they inflated the stock market bubble, and then caused the Great Crash. Since the Reagan revolution, these superfluous profits have fed corporate mergers and takeovers, driven the dot-com craze, financed the “shadow banking” system of hedge funds and securitized investment vehicles, fueled monetary meltdowns in every hemisphere and inflated the housing bubble.
  • we doubt the moral worth of consumer culture. Like the abstemious ant who scolds the feckless grasshopper as winter approaches, we think that saving is the right thing to do. Even as we shop with abandon, we feel that if only we could contain our unruly desires, we’d be committing ourselves to a better future. But we’re wrong.
  • Consumer spending is not only the key to economic recovery in the short term; it’s also necessary for balanced growth in the long term. If our goal is to repair our damaged economy, we should bank on consumer culture — and that entails a redistribution of income away from profits toward wages, enabled by tax policy and enforced by government spending.

Culture Clash at a Chinese-Owned Plant in Ohio - The New York Times - 1 views

  • When a giant Chinese glassmaker arrived here in 2014 and began spending what would become more than a half-billion dollars to fix up an abandoned General Motors plant, it seemed like a tale from opposite land: The Chinese are supposedly stealing American jobs — as no less an authority than President Trump has pointed out.
  • But now the Chinese were suddenly creating them. More than 1,500 jobs, in fact.
  • At Fuyao, a major culture clash is playing out on the factory floor, with some workers questioning the company’s commitment to operating under American supervision and American norms.
