geology anthropocene holocene history language science

shared by Javier E on 23 Jul 18 - No Cached
  • , in 2000, the Nobel Prize-winning chemist Paul Crutzen won permanent fame for stratigraphy. He proposed that humans had so throughly altered the fundamental processes of the planet—through agriculture, climate change, and nuclear testing, and other phenomena—that a new geological epoch had commenced: the Anthropocene, the age of humans.
  • Zalasiewicz should know. He is the chair of the Anthropocene working group, which the ICS established in 2009 to investigate whether the new epoch deserved a place in stratigraphic time.
  • In 2015, the group announced that the Anthropocene was a plausible new layer and that it should likely follow the Holocene. But the team has yet to propose a “golden spike” for the epoch: a boundary in the sedimentary rock record where the Anthropocene clearly begins.
  • ...12 more annotations...
  • Officially, the Holocene is still running today. You have lived your entire life in the Holocene, and the Holocene has constituted the geological “present” for as long as there have been geologists.But if we now live in a new epoch, the Anthropocene, then the ICS will have to chop the Holocene somewhere. It will have to choose when the Holocene ended, and it will move some amount of time out of the purview of the Holocene working group and into that of the Anthropocene working group.
  • This is politically difficult. And right now, the Anthropocene working group seems intent on not carving too deep into the Holocene. In a paper published earlier this year in Earth-Science Reviews, the Anthropocene working group’s members strongly imply that they will propose starting the new epoch in the mid-20th century.
  • Some geologists argue that the Anthropocene started even earlier: perhaps 4,000 or 6,000 years ago, as farmers began to remake the land surface.“Most of the world’s forests that were going to be converted to cropland and agriculture were already cleared well before 1950,” says Bill Ruddiman, a geology professor at the University of Virginia and an advocate of this extremely early Anthropocene.
  • “Most of the world’s prairies and steppes that were going to be cleared for crops were already gone, by then. How can you argue the Anthropocene started in 1950 when all of the major things that affect Earth’s surface were already over?”Van der Pluijm agreed that the Anthropocene working group was picking 1950 for “not very good reasons.”“Agriculture was the revolution that allowed society to develop,” he said. “That was really when people started to force the land to work for them. That massive land movement—it’s like a landslide, except it’s a humanslide. And it is not, of course, as dramatic as today’s motion of land, but it starts the clock.”
  • This muddle had to stop. The Holocene comes up constantly in discussions of modern global warming. Geologists and climate scientists did not make their jobs any easier by slicing it in different ways and telling contradictory stories about it.
  • This process started almost 10 years ago. For this reason, Zalasiewicz, the chair of the Anthropocene working group, said he wasn’t blindsided by the new subdivisions at all. In fact, he voted to adopt them as a member of the Quaternary working group.“Whether the Anthropocene works with a unified Holocene or one that’s in three parts makes for very little difference,” he told me.In fact, it had made the Anthropocene group’s work easier. “It has been useful to compare the scale of the two climate events that mark the new boundaries [within the Holocene] with the kind of changes that we’re assessing in the Anthropocene. It has been quite useful to have the compare and contrast,” he said. “Our view is that some of the changes in the Anthropocene are rather bigger.”
  • Zalasiewicz said that he and his colleagues were going as fast as they could. When the working group group began its work in 2009, it was “really starting from scratch,” he told me.While other working groups have a large body of stratigraphic research to consider, the Anthropocene working group had nothing. “We had to spend a fair bit of time deciding whether the Anthropocene was geology at all,” he said. Then they had to decide where its signal could show up. Now, they’re looking for evidence that shows it.
  • This cycle of “glacials” and “interglacials” has played out about 50 times over the last several million years. When the Holocene began, it was only another interglacial—albeit the one we live in. Until recently, glaciers were still on schedule to descend in another 30,000 years or so.Yet geologists still call the Holocene an epoch, even though they do not bestow this term on any of the previous 49 interglacials. It get special treatment because we live in it.
  • Much of this science is now moot. Humanity’s vast emissions of greenhouse gas have now so warmed the climate that they have offset the next glaciation. They may even knock us out of the ongoing cycle of Ice Ages, sending the Earth hurtling back toward a “greenhouse” climate after the more amenable “icehouse” climate during which humans evolved.For this reason, van der Pluijm wants the Anthropocene to supplant the Holocene entirely. Humans made their first great change to the environment at the close of the last glaciation, when they seem to have hunted the world’s largest mammals—the wooly mammoth, the saber-toothed tiger—to extinction. Why not start the Anthropocene then?He would even rename the pre-1800 period “the Holocene Age” as a consolation prize:
  • Zalasiewicz said he would not start the Anthropocene too early in time, as it would be too work-intensive for the field to rename such a vast swath of time. “The early-Anthropocene idea would crosscut against the Holocene as it’s seen by Holocene workers,” he said. If other academics didn’t like this, they could create their own timescales and start the Anthropocene Epoch where they choose. “We have no jurisdiction over the word Anthropocene,” he said.
  • Ruddiman, the University of Virginia professor who first argued for a very early Anthropocene, now makes an even broader case. He’s not sure it makes sense to formally define the Anthropocene at all. In a paper published this week, he objects to designating the Anthropocene as starting in the 1950s—and then he objects to delineating the Anthropocene, or indeed any new geological epoch, by name. “Keep the use of the term informal,” he told me. “Don’t make it rigid. Keep it informal so people can say the early-agricultural Anthropocene, or the industrial-era Anthropocene.”
  • “This is the age of geochemical dating,” he said. Geologists have stopped looking to the ICS to place each rock sample into the rock sequence. Instead, field geologists use laboratory techniques to get a precise year or century of origin for each rock sample. “The community just doesn’t care about these definitions,” he said.

How to be a human lie detector of fake news - CNN - 0 views

www.cnn.com/...index.html

shared by katherineharron on 25 Oct 19 - No Cached
  • Fake news existed long before the internet. In an essay on political lying in the early 18th century, the writer Jonathan Swift noted that "Falsehood flies and the truth comes limping after it." You have to hire a train to pull the truth, explained English pastor Charles Spurgeon in the 19th century, while a lie is "light as a feather ... a breath will carry it."
  • MIT researchers recently studied more than 10 years' worth of data on the most shared stories on Facebook. Their study covered conspiracy theories about the Boston bombings, misleading reports on natural disasters, unfounded business rumors and incorrect scientific claims. There is an inundation of false medical advice online, for example, that encourages people to avoid life-saving treatments such as vaccines and promotes unproven therapies. (Gwyneth Paltrow's Goop is just one example.)
  • The psychological research does, however, offer us a silver lining to this storm cloud, with various experiments demonstrating that people can learn to be better lie detectors with a little training in critical thinking.
  • ...6 more annotations...
  • If you would like to improve your own lie detection, a good first step is to learn the common logical fallacies -- red herrings, appeals to ignorance, straw men and "ad populum" appeals to the bandwagon -- that purveyors of misinformation may use to create the illusion of truth.
  • These efforts are often called "inoculations," since they use a real-life example in one domain to teach people about the strategies used to spread lies and therefore equipping people to spot them more easily. Educating people about the tobacco industry's attempts to question the medical consensus on smoking, for example, led people to be more skeptical of articles denying climate change, according to one study.
  • Another project aimed to inoculate students at North Carolina State University in Raleigh, involved a course on misinformation throughout history. The class was taught about everything from the myth that aliens somehow built the Egyptian pyramids to the theories that NASA's moon landings were faked. Along the way, the students had to identify the erroneous logic that helped create the arguments, and the motivations that may lead some people to spread those ideas.
  • You could also try basic strategies such as cross-checking different outlets and finding the original source of a claim. You might also look at independent fact-checking websites used in the MIT study such as Snopes, PolitiFact and TruthOrFiction.com.
  • The psychological literature offers us one good strategy against bias, called the "consider the opposite" method. This involves asking yourself whether you would have been so credulous of a claim if its opinions had differed from your own. And if not, what kind of additional scrutiny might you have applied? This should help you to identify the weaknesses in your own thinking.
  • Falsehoods may fly, but with this lie detection kit, you can better ensure your actions and beliefs remain grounded in the truth.

  • 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.

Does This Ad Make Me Fat? - NYTimes.com - 0 views

  • A team of researchers walked every street in 228 census tracts around Los Angeles and New Orleans and recorded every outdoor ad they saw. Another group surveyed 2,881 residents of the same census tracts by telephone, paying them to report their height, weight and other information. After analyzing this hard-won data, the authors conclude: “For every 10 percent increase in food advertisements, the odds of being obese increased by 5 percent.” That is, areas with more outdoor food ads have a higher proportion of obese people than ones with fewer ads.
  • The problem is that their policy recommendations rest on a crucial but unjustified assumption: that any link between obesity and advertising occurs because more advertising causes higher rates of obesity. But the study at hand showed only an association: people living in areas with more food ads were more likely to be obese than people living in areas with fewer food ads. To be fair, the researchers correctly note that additional steps would be needed to prove that food ads cause obesity. But until those steps are taken, talk of restricting ads is premature. In fact, it is easy to imagine how the causation could run the opposite way (something the article did not mention): If food vendors believe obese people are more likely than non-obese people to buy their products, they will place more ads in areas where obese people already live. Suppose we counted ads for fitness-oriented products like bicycles and bottled water, and found more of those ads in places with less obesity. Would it then be wise anti-obesity policy to subsidize such ads? Or would the smarter conclusion be that the fitness companies suspect that the obese are less likely than the fit to buy their products?
  • When we seek to base policy on evidence, we must remember that not all “evidence” is created equal. Taken at face value, the study on ads and obesity provides some indication that the two are linked, but no evidence that food ads cause obesity. The fact that the causal conclusion may coincide with a moral belief — that it is wrong to tempt people who overeat by showing them ads for food — does not make it valid.

  • Instagram’s Reels video service is designed to show users streams of short videos on topics the system decides will interest them, such as sports, fashion or humor.&nbsp;
  • The Meta Platforms META -1.04%decrease; red down pointing triangle-owned social app does the same thing for users its algorithm decides might have a prurient interest in children, testing by The Wall Street Journal showed.
  • The Journal sought to determine what Instagram’s Reels algorithm would recommend to test accounts set up to follow only young gymnasts, cheerleaders and other teen and preteen influencers active on the platform.
  • ...30 more annotations...
  • Following what it described as Meta’s unsatisfactory response to its complaints, Match began canceling Meta advertising for some of its apps, such as Tinder, in October. It has since halted all Reels advertising and stopped promoting its major brands on any of Meta’s platforms. “We have no desire to pay Meta to market our brands to predators or place our ads anywhere near this content,” said Match spokeswoman Justine Sacco.
  • The Journal set up the test accounts after observing that the thousands of followers of such young people’s accounts often include large numbers of adult men, and that many of the accounts who followed those children also had demonstrated interest in sex content related to both children and adults
  • The Journal also tested what the algorithm would recommend after its accounts followed some of those users as well, which produced more-disturbing content interspersed with ads.
  • The Canadian Centre for Child Protection, a child-protection group, separately ran similar tests on its own, with similar results.
  • Meta said the Journal’s tests produced a manufactured experience that doesn’t represent what billions of users see. The company declined to comment on why the algorithms compiled streams of separate videos showing children, sex and advertisements, but a spokesman said that in October it introduced new brand safety tools that give advertisers greater control over where their ads appear, and that Instagram either removes or reduces the prominence of four million videos suspected of violating its standards each month.&nbsp;
  • The Journal reported in June that algorithms run by Meta, which owns both Facebook and Instagram, connect large communities of users interested in pedophilic content. The Meta spokesman said a task force set up after the Journal’s article has expanded its automated systems for detecting users who behave suspiciously, taking down tens of thousands of such accounts each month. The company also is participating in a new industry coalition to share signs of potential child exploitation.
  • “Our systems are effective at reducing harmful content, and we’ve invested billions in safety, security and brand suitability solutions,” said Samantha Stetson, a Meta vice president who handles relations with the advertising industry. She said the prevalence of inappropriate content on Instagram is low, and that the company invests heavily in reducing it.
  • Even before the 2020 launch of Reels, Meta employees understood that the product posed safety concerns, according to former employees.
  • Robbie McKay, a spokesman for Bumble, said it “would never intentionally advertise adjacent to inappropriate content,” and that the company is suspending its ads across Meta’s platforms.
  • Meta created Reels to compete with TikTok, the video-sharing platform owned by Beijing-based ByteDance. Both products feed users a nonstop succession of videos posted by others, and make money by inserting ads among them. Both companies’ algorithms show to a user videos the platforms calculate are most likely to keep that user engaged, based on his or her past viewing behavior
  • The Journal reporters set up the Instagram test accounts as adults on newly purchased devices and followed the gymnasts, cheerleaders and other young influencers. The tests showed that following only the young girls triggered Instagram to begin serving videos from accounts promoting adult sex content alongside ads for major consumer brands, such as one for Walmart that ran after a video of a woman exposing her crotch.&nbsp;
  • When the test accounts then followed some users who followed those same young people’s accounts, they yielded even more disturbing recommendations. The platform served a mix of adult pornography and child-sexualizing material, such as a video of a clothed girl caressing her torso and another of a child pantomiming a sex act.
  • Experts on algorithmic recommendation systems said the Journal’s tests showed that while gymnastics might appear to be an innocuous topic, Meta’s behavioral tracking has discerned that some Instagram users following preteen girls will want to engage with videos sexualizing children, and then directs such content toward them.
  • Instagram’s system served jarring doses of salacious content to those test accounts, including risqué footage of children as well as overtly sexual adult videos—and ads for some of the biggest U.S. brands.
  • Preventing the system from pushing noxious content to users interested in it, they said, requires significant changes to the recommendation algorithms that also drive engagement for normal users. Company documents reviewed by the Journal show that the company’s safety staffers are broadly barred from making changes to the platform that might reduce daily active users by any measurable amount.
  • The test accounts showed that advertisements were regularly added to the problematic Reels streams. Ads encouraging users to visit Disneyland for the holidays ran next to a video of an adult acting out having sex with her father, and another of a young woman in lingerie with fake blood dripping from her mouth. An ad for Hims ran shortly after a video depicting an apparently anguished woman in a sexual situation along with a link to what was described as “the full video.”
  • Current and former Meta employees said in interviews that the tendency of Instagram algorithms to aggregate child sexualization content from across its platform was known internally to be a problem. Once Instagram pigeonholes a user as interested in any particular subject matter, they said, its recommendation systems are trained to push more related content to them.
  • Part of the problem is that automated enforcement systems have a harder time parsing video content than text or still images. Another difficulty arises from how Reels works: Rather than showing content shared by users’ friends, the way other parts of Instagram and Facebook often do, Reels promotes videos from sources they don’t follow
  • In an analysis conducted shortly before the introduction of Reels, Meta’s safety staff flagged the risk that the product would chain together videos of children and inappropriate content, according to two former staffers. Vaishnavi J, Meta’s former head of youth policy, described the safety review’s recommendation as: “Either we ramp up our content detection capabilities, or we don’t recommend any minor content,” meaning any videos of children.
  • At the time, TikTok was growing rapidly, drawing the attention of Instagram’s young users and the advertisers targeting them. Meta didn’t adopt either of the safety analysis’s recommendations at that time, according to J.
  • Stetson, Meta’s liaison with digital-ad buyers, disputed that Meta had neglected child safety concerns ahead of the product’s launch. “We tested Reels for nearly a year before releasing it widely, with a robust set of safety controls and measures,” she said.&nbsp;
  • After initially struggling to maximize the revenue potential of its Reels product, Meta has improved how its algorithms recommend content and personalize video streams for users
  • Among the ads that appeared regularly in the Journal’s test accounts were those for “dating” apps and livestreaming platforms featuring adult nudity, massage parlors offering “happy endings” and artificial-intelligence chatbots built for cybersex. Meta’s rules are supposed to prohibit such ads.
  • The Journal informed Meta in August about the results of its testing. In the months since then, tests by both the Journal and the Canadian Centre for Child Protection show that the platform continued to serve up a series of videos featuring young children, adult content and apparent promotions for child sex material hosted elsewhere.&nbsp;
  • As of mid-November, the center said Instagram is continuing to steadily recommend what the nonprofit described as “adults and children doing sexual posing.”
  • Meta hasn’t offered a timetable for resolving the problem or explained how in the future it would restrict the promotion of inappropriate content featuring children.&nbsp;
  • The Journal’s test accounts found that the problem even affected Meta-related brands. Ads for the company’s WhatsApp encrypted chat service and Meta’s Ray-Ban Stories glasses appeared next to adult pornography. An ad for Lean In Girls, the young women’s empowerment nonprofit run by former Meta Chief Operating Officer Sheryl Sandberg, ran directly before a promotion for an adult sex-content creator who often appears in schoolgirl attire. Sandberg declined to comment.&nbsp;
  • Through its own tests, the Canadian Centre for Child Protection concluded that Instagram was regularly serving videos and pictures of clothed children who also appear in the National Center for Missing and Exploited Children’s digital database of images and videos confirmed to be child abuse sexual material. The group said child abusers often use the images of the girls to advertise illegal content for sale in dark-web forums.
  • The nature of the content—sexualizing children without generally showing nudity—reflects the way that social media has changed online child sexual abuse, said Lianna McDonald, executive director for the Canadian center. The group has raised concerns about the ability of Meta’s algorithms to essentially recruit new members of online communities devoted to child sexual abuse, where links to illicit content in more private forums proliferate.
  • “Time and time again, we’ve seen recommendation algorithms drive users to discover and then spiral inside of these online child exploitation communities,” McDonald said, calling it disturbing that ads from major companies were subsidizing that process.

    I have never think about the context of where the ads are in. I though ads just pops up randomly and now I know that there are actually codes behind where the ads appears. Why is putting ads besides extremist video a bad idea? I think it is probably because they people would mistaken that the company sponsor the video. Actually I am not very sure about why it is a bad thing. However, ads can definitely be more efficient in the right context. Different people watch different kind of video, targeting the potential costumers. It would benefit both the viewer and the company. --Sissi (4/3/2017)

  • First, making a choice is physically exhausting, literally, so that somebody forced to make a number of decisions in a row is likely to get lazy and dumb.
  • Second, having too many choices can make us less likely to come to a conclusion. In a famous study of the so-called "paradox of choice", psychologists Mark Lepper and Sheena Iyengar found that customers presented with six jam varieties were more likely to buy one than customers offered a choice of 24.
  • ...7 more annotations...
  • Many of our mistakes stem from a central "availability bias." Our brains are computers, and we like to access recently opened files, even though many decisions require a deep body of information that might require some searching. Cheap example: We remember the first, last, and peak moments of certain experiences.
  • The third check against the theory of the rational consumer is the fact that we're social animals. We let our friends and family and tribes do our thinking for us
  • neurologists are finding that many of the biases behavioral economists perceive in decision-making start in our brains. "Brain studies indicate that organisms seem to be on a hedonic treadmill, quickly habituating to homeostasis," McFadden writes. In other words, perhaps our preference for the status quo isn't just figuratively our heads, but also literally sculpted by the hand of evolution inside of our brains.
  • The popular psychological theory of "hyperbolic discounting" says people don't properly evaluate rewards over time. The theory seeks to explain why many groups -- nappers, procrastinators, Congress -- take rewards now and pain later, over and over again. But neurology suggests that it hardly makes sense to speak of "the brain," in the singular, because it's two very different parts of the brain that process choices for now and later. The choice to delay gratification is mostly processed in the frontal system. But studies show that the choice to do something immediately gratifying is processed in a different system, the limbic system, which is more viscerally connected to our behavior, our "reward pathways," and our feelings of pain and pleasure.
  • the final message is that neither the physiology of pleasure nor the methods we use to make choices are as simple or as single-minded as the classical economists thought. A lot of behavior is consistent with pursuit of self-interest, but in novel or ambiguous decision-making environments there is a good chance that our habits will fail us and inconsistencies in the way we process information will undo us.
  • Our brains seem to operate like committees, assigning some tasks to the limbic system, others to the frontal system. The "switchboard" does not seem to achieve complete, consistent communication between different parts of the brain. Pleasure and pain are experienced in the limbic system, but not on one fixed "utility" or "self-interest" scale. Pleasure and pain have distinct neural pathways, and these pathways adapt quickly to homeostasis, with sensation coming from changes rather than levels
  • Social networks are sources of information, on what products are available, what their features are, and how your friends like them. If the information is accurate, this should help you make better choices. On the other hand, it also makes it easier for you to follow the crowd rather than engaging in the due diligence of collecting and evaluating your own information and playing it against your own preferences

I Actually Read Woody Allen's Memoir - The Atlantic - 0 views

shared by Javier E on 07 Jun 20 - No Cached
  • I’m a Woody Allen person, not because I disbelieve Dylan—in fact, I believe her. I’m a Woody Allen person because his movies helped shape me, and I can’t unsee them, the way I can’t un-read The Great Gatsby or un-hear “Gimme Shelter.” These are things that informed my sensibilities. All of them are part of me.
  • As to our opinion about his past, one thing is for sure: He couldn’t care less about it. “Rather than live on in the hearts and mind of the public,” he says in the final lines of the book, “I prefer to live on in my apartment.”Exit laughing.
  • the scene in Hannah and Her Sisters in which the Woody Allen character, distraught by his realization that there is no God and considering suicide, stumbles into a revival house to find the movie playing. He says in voice-over: The movie was a film that I’d seen many times in my life since I was a kid, and I always loved it. And I’m watching these people up on the screen and I started getting hooked on the film. And I started to feel,&nbsp; How can you even think of killing yourself? I mean, isn’t it so stupid? I mean, look at all the people up there on the screen. They’re real funny—and what if the worst is true? What if there’s no God and you only go around once and that’s it? Well, you know, don’t you want to be part of the experience? I did.I do.
  • ...7 more annotations...
  • Can we still enjoy his work?&nbsp;&nbsp;Of course we can, because the movies don’t really belong to Woody Allen any more than they do to you and me.
  • Some wrongs are so great that no legal or bureaucratic process can ever make things right. At some point, the only way to get unchained from a monster is through forgiveness. It would seem impossible for Geimer to be able to forgive Polanski, but she did—who understands how grace operates?—and has apparently been at peace ever since.
  • Woody Allen taught us that New York is the center of the world and L.A. is outer space. He installed himself in Elaine’s for a thousand dinners in the company of glittering figures of yesteryear (Norman Mailer! Liza Minnelli! Bill Bradley!) and made movie after movie and became one of the famous people the rest of the country associates most closely with the city.
  • He’s a 42-year-old guy with a 12th grade girlfriend, and if you want to understand the ’70s, maybe I have to tell you only that Vincent Canby’s review in The New York Times made no particular note of this fact other than to describe Tracy—played by Mariel Hemingway—as “a beautiful, 17-year-old nymphet with a turned-down mouth.” Or I could tell you that Manhattan was nominated for two Academy Awards and was widely loved by the in-crowd.
  • Soon enough he was writing, directing, and then acting in his own movies. He developed a particular method of moviemaking that was in some regards reminiscent of the studio system: he worked fast, almost never rehearsed, and rarely shot multiple takes or engineered complex shots: “As long as you’re dealing with comedy, particularly broad comedy, all you want is the scene should be lit, loud and fast.”
  • Allen is one of the great storytellers of his time, completely original, and any version of his life—including this one, in which we are obviously in the hands of an unreliable narrator, although no more so than in any of his autobiographical movies—can only be riveting. In a matter of phrases, he accomplishes things it takes a lesser writer several chapters to establish
  • We have the damn thing. What are we going to do with it? I suppose we could start—why not?—by actually reading it. And within just a phrase or two, you realize why people were afraid of it: Allen is a matchless comic writer and one whose voice is so well known by his aging fans that it’s as though the book is pouring into you through a special receiver dedicated just to him. Woody Allen does a great Woody Allen.

EU to limit political ads, ban use of certain personal info - The Washington Post - 0 views

  • Facebook, which has faced heavy criticism for its lack of transparency on political ads, welcomed the move.
  • “We have long called for EU-wide regulation on political ads and are pleased that the Commission’s proposal addresses some of the more difficult questions, in particular when it comes to cross border advertising,” the company, which recently renamed itself Meta, said in a press statement.
  • Google said in a blog post that it supported the proposals and recommended the commission clearly define political ads and spell out responsibilities for tech platforms and advertisers while still keeping the rules flexible.
  • ...4 more annotations...
  • Twitter, which banned all political ads in 2019, said it believed that “political reach should be earned, not bought” and noted that it has also restricted and removed micro-targeting from other types of ads like cause-based ones.
  • Under the EU plan, political ads would have to be clearly labelled, and prominently display the name of the sponsor, with a transparency notice that explains how much the ad cost and where the funds to pay for it came from. The material would have to have a direct link to the vote or poll concerned.
  • Information must be available about the basis on which a person, or group of people, is being targeted by the advertisement, and what kind of amplification tools are being used to help the sponsor reach a wider audience. Ads would be banned if such criteria cannot be met.
  • Jourova told reporters that “the sensitive data that people decide to share with friends on social media cannot be used to target them for political purposes.” She said that “either companies like Facebook are able to publicly say who they are targeting, why and how or they will not be able to do it.”

How Galileo Changed Your Life - Biography - 0 views

shared by caelengrubb on 17 Jan 21 - No Cached
  • Galileo’s contributions to the fields of astronomy, physics, mathematics, and philosophy have led many to call him the father of modern science.
  • But his controversial theories, which impacted how we see and understand the solar system and our place within it, led to serious conflict with the Catholic Church and the long-time suppression of his achievements
  • Galileo developed one of the first telescopesGalileo didn’t invent the telescope — it was invented by Dutch eyeglass makers — but he made significant improvements to it.
  • ...18 more annotations...
  • His innovations brought him both professional and financial success. He was given a lifetime tenure position at the University of Padua, where he had been teaching for several years, at double his salary.
  • And he received a contract to produce his telescopes for a group of Venetian merchants, eager to use them as a navigational tool.
  • He helped created modern astronomyGalileo turned his new, high-powered telescope to the sky. In early 1610, he made the first in a remarkable series of discoveries.
  • While the scientific doctrine of the day held that space was perfect, unchanging environments created by God, Galileo’s telescope helped change that view
  • His studies and drawings showed the Moon had a rough, uneven surface that was pockmarked in some places, and was actually an imperfect sphere
  • He was also one of the first people to observe the phenomena known as sunspots, thanks to his telescope which allowed him to view the sun for extended periods of time without damaging the eye.
  • Galileo helped prove that the Earth revolved around the sunIn 1610, Galileo published his new findings in the book Sidereus Nuncius, or Starry Messenger, which was an instant success
  • He became close with a number of other leading scientists, including Johannes Kepler. A German astronomer and mathematician, Kepler’s work helped lay the foundations for the later discoveries of Isaac Newton and others.
  • Kepler’s experiments had led him to support the idea that the planets, Earth included, revolved around the sun. This heliocentric theory, as well as the idea of Earth’s daily rotational turning, had been developed by Polish astronomer Nicolaus Copernicus half a century earlier
  • Their belief that the Sun, and not the Earth, was the gravitational center of the universe, upended almost 2,000 years of scientific thinking, dating back to theories about the fixed, unchanging universe put forth by the Greek philosopher and scientist Aristotle.
  • Galileo had been testing Aristotle’s theories for years, including an experiment in the late 16th century in which he dropped two items of different masses from the Leaning Tower of Pisa, disproving Aristotle’s belief that objects would fall at differing speeds based on their weight (Newton later improved upon this work).
  • Galileo paid a high price for his contributionsBut challenging the Aristotelian or Ptolemaic theories about the Earth’s role in the universe was dangerous stuff.
  • Geocentrism was, in part, a theoretical underpinning of the Roman Catholic Church. Galileo’s work brought him to the attention of Church authorities, and in 1615, he was called before the Roman Inquisition, accused of heresy for beliefs which contradicted Catholic scripture.
  • The following year, the Church banned all works that supported Copernicus’ theories and forbade Galileo from publicly discussing his works.
  • In 1632, after the election of a new pope who he considered more liberal, he published another book, Dialogue on the Two Chief World Systems, Ptolemaic and Copernican, which argued both sides of the scientific (and religious) debate but fell squarely on the side of Copernicus’ heliocentrism.
  • Galileo was once again summoned to Rome. In 1633, following a trial, he was found guilty of suspected heresy, forced to recant his views and sentenced to house arrest until his death in 1642.
  • It took nearly 200 years after Galileo’s death for the Catholic Church to drop its opposition to heliocentrism.
  • In 1992, after a decade-long process and 359 years after his heresy conviction, Pope John Paul II formally expressed the Church’s regret over Galileo’s treatment.

Elon Musk Hates Ads. Twitter Needs Them. That May Be a Problem. - The New York Times - 0 views

  • Since he started pursuing his $44 billion purchase of Twitter — and for years before that — the world’s richest man has made clear that advertising is not a priority.
  • Ads account for roughly 90 percent of Twitter’s revenue.
  • They have cited a litany of complaints, including that the company cannot target ads nearly as well as competitors like Facebook, Google and Amazon.
  • ...10 more annotations...
  • Now, numerous advertising executives say they’re willing to move their money elsewhere, especially if Mr. Musk eliminates the safeguards that allowed Twitter to remove racist rants and conspiracy theories.
  • “At the end of the day, it’s not the brands who need to be concerned, because they’ll just spend their budgets elsewhere — it’s Twitter that needs to be concerned,” said David Jones
  • On Wednesday night, at Twitter’s annual NewFronts presentation for advertisers at Pier 17 in New York, company representatives stressed Twitter’s value for marketers: as a top destination for people to gather and discuss major cultural moments like sporting events or the Met Gala, increasingly through video posts.
  • “Twitter’s done a better job than many platforms at building trust with advertisers — they’ve been more progressive, more responsive and more humble about initiating ways to learn,” said Mark Read
  • Twitter earns the vast majority of its ad revenue from brand awareness campaigns, whose effectiveness is much harder to evaluate than ads that target users based on their interests or that push for a direct response, such as clicking through to a website.
  • Twitter’s reach is also narrower than many rivals, with 229 million users who see ads, compared with 830 million users on LinkedIn and 1.96 billion daily users on Facebook.
  • “Even the likes of LinkedIn have eclipsed the ability for us to target consumers beyond what Twitter is providing,” he said. “We’re going to go where the results are, and with a lot of our clients, we haven’t seen the performance on Twitter from an ad perspective that we have with other platforms.”
  • Twitter differs from Facebook, whose millions of small and midsize advertisers generate the bulk of the company’s revenue and depend on its enormous size and targeting abilities to reach customers. Twitter’s clientele is heavily weighted with large, mainstream companies, which tend to be wary of their ads appearing alongside problematic content.
  • On Twitter, he has criticized ads as “manipulating public opinion” and discussed his refusal to “pay famous people to fake endorse.”
  • “There’s a fork in the road, where Path A leads to an unfiltered place with the worst of human behavior and no brands want to go anywhere near it,” said Mr. Jones of Brandtech. “And Path B has one of the world’s genius entrepreneurs, who knows a lot about running companies, unleashing a wave of innovation that has people looking back in a few years and saying, ‘Remember when everyone was worried about Musk coming in?’”

social media micropayments ad-financed business model privacy facebook

  • 93 percent of the public believes that “being in control of who can get information about them is important,” and yet the amount of information we generate online has exploded and we seldom know where it all goes.
  • the pop-up and the ad-financed business model. The former is annoying but it’s the latter that is helping destroy the fabric of a rich, pluralistic Internet.
  • Facebook makes about 20 cents per user per month in profit. This is a pitiful sum, especially since the average user spends an impressive 20 hours on Facebook every month, according to the company. This paltry profit margin drives the business model: Internet ads are basically worthless unless they are hyper-targeted based on tracking and extensive profiling of users. This is a bad bargain, especially since two-thirds of American adults don’t want ads that target them based on that tracking and analysis of personal behavior.

  • This way of doing business rewards huge Internet platforms, since ads that are worth so little can support only companies with hundreds of millions of users.
  • Ad-based businesses distort our online interactions. People flock to Internet platforms because they help us connect with one another or the world’s bounty of information — a crucial, valuable function. Yet ad-based financing means that the companies have an interest in manipulating our attention on behalf of advertisers, instead of letting us connect as we wish.
  • Many users think their feed shows everything that their friends post. It doesn’t. Facebook runs its billion-plus users’ newsfeed by a proprietary, ever-changing algorithm that decides what we see. If Facebook didn’t have to control the feed to keep us on the site longer and to inject ads into our stream, it could instead offer us control over this algorithm.
  • we’re not starting from scratch. Micropayment systems that would allow users to spend a few cents here and there, not be so easily tracked by all the Big Brothers, and even allow personalization were developed in the early days of the Internet. Big banks and large Internet platforms didn’t show much interest in this micropayment path, which would limit their surveillance abilities. We can revive it.
  • What to do? It’s simple: Internet sites should allow their users to be the customers. I would, as I bet many others would, happily pay more than 20 cents per month for a Facebook or a Google that did not track me, upgraded its encryption and treated me as a customer whose preferences and privacy matter.
  • Many people say that no significant number of users will ever pay directly for Internet services. But that is because we are misled by the mantra that these services are free. With growing awareness of the privacy cost of ads, this may well change. Millions of people pay for Netflix despite the fact that pirated copies of many movies are available free. We eventually pay for ads, anyway, as that cost is baked into products we purchase
  • A seamless, secure micropayment system that spreads a few pennies at a time as we browse a social network, up to a preset monthly limit, would alter the whole landscape for the better.
  • Many nonprofits and civic groups that were initially thrilled about their success in using Facebook to reach people are now despondent as their entries are less and less likely to reach people who “liked” their posts unless they pay Facebook to help boost their updates.
  • If even a quarter of Facebook’s 1.5 billion users were willing to pay $1 per month in return for not being tracked or targeted based on their data, that would yield more than $4 billion per year — surely a number worth considering.
  • Mr. Zuckerberg has reportedly spent more than $30 million to buy the homes around his in Palo Alto, Calif., and more than $100 million for a secluded parcel of land in Hawaii. He knows privacy is worth paying for. So he should let us pay a few dollars to protect ours.

      It's hard to imagine a "mild" case of dementia. I've always looked at all dementia as horrifying and intense.

      That's great!
  • the pooled percentage was 45.2 percent for the combined group of mild AD dementia and MCI that later progressed to AD.

      The more mild the better!
  • We found that approximately 45 percent of all those who are cognitively impaired or diagnosed with AD-dementia had early AD.

      This means it can be caught early!
  • Diagnosis and severity were assessed by consensus dementia review.

      I would like to know what the criteria is like...
  • According to the researchers the finding that half of the people living with AD have mild disease underscores the need for research and interventions to slow decline or prevent progression of this burdensome disease.

      There more hope to treat mild dementia I'm guessing?
  • The researchers believe that most people who have AD are still at a stage when there is still some preserved quality of life.

  • Facebook’s new plan to host news publications’ stories directly is not only about page views, advertising revenue or the number of seconds it takes for an article to load. It is about who owns the relationship with readers.
  • It’s why Google, a search engine, started a social network and why Facebook, a social network, started a search engine. It’s why Amazon, a shopping site, made a phone and why Apple, a phone maker, got into shopping.
  • Facebook’s experiment, called instant articles, is small to start — just a few articles from nine media companies, including The New York Times. But it signals a major shift in the relationship between publications and their readers. If you want to read the news, Facebook is saying, come to Facebook, not to NBC News or The Atlantic or The Times — and when you come, don’t leave. (For now, these articles can be viewed on an iPhone running the Facebook app.)

  • The front page of a newspaper and the cover of a magazine lost their dominance long ago.
  • Facebook executives have insisted that they intend to exert no editorial control because they leave the makeup of the news feed to the algorithm. But an algorithm is not autonomous. It is written by humans and tweaked all the time. Advertisement Continue reading the main story Advertisement Continue reading the main story
  • “In digital, every story becomes unbundled from each other, so if you’re not thinking of each story as living on its own, it’s tying yourself back to an analog era,” Mr. Kim said.
  • But news reports, like albums before them, have not been created that way. One of the services that editors bring to readers has been to use their news judgment, considering a huge range of factors, when they decide how articles fit together and where they show up. The news judgment of The New York Times is distinct from that of The New York Post, and for generations readers appreciated that distinction.
  • That raises some journalistic questions. The news feed algorithm works, in part, by showing people more of what they have liked in the past. Some studies have suggested that means they might not see as wide a variety of news or points of view, though others, including one by Facebook researchers, have found they still do.
  • Tech companies, Facebook included, are notoriously fickle with their algorithms. Publications became so dependent on Facebook in the first place because of a change in its algorithm that sent more traffic their way. Later, another change demoted articles from sites that Facebook deemed to run click-bait headlines. Then last month, Facebook decided to prioritize some posts from friends over those from publications.
