Hillary Clinton Sets Up A Fight With Bernie Sanders Over Paid Leave - 0 views

  • Democratic presidential candidate Hillary Clinton on Thursday offered new details about her plan to make sure all workers can take time off, with pay, in order to care for a newborn or sick relative.
  • During that time, the worker would be eligible to receive replacement wages, up to two-thirds of his or her salary.
  • The proposal, if enacted, would patch a major gap in America’s safety net. Workers in every other developed country are entitled to paid leave, in some cases for more than a year.
  • ...6 more annotations...
  • Some companies provide paid leave anyway. In the last year, high-profile employers like Facebook and Goldman Sachs introduced or expanded paid leave for their employees.
  • But Clinton’s proposal differs from the bill in one crucial way. In order to finance the replacement wages that workers would get, the Gillibrand-DeLauro bill would impose a small payroll tax, of 0.4 percent, that employers and employees would split evenly.
  • Clinton has criticized that approach repeatedly because it would mean higher taxes on lower- and middle-income workers.
  • Sen. Marco Rubio (R-Fla.), the only Republican presidential candidate to address the issue formally, has said he’d offer small tax breaks to companies that offer paid leave -- an approach unlikely to have much impact, except perhaps to help well-off workers.
  • “The benefit of being one of the last countries in the world to adopt paid maternity leave is that we have been able to learn from other countries' experiences and the results are clear,” Betsey Stevenson, a University of Michigan economist and former adviser to President Barack Obama, told the Huffington Post on Thursday.
  • To advocates like Heather Boushey, chief economist and executive director of the Washington Center for Equitable Growth, that’s a welcome sign that American politics is finally talking about the challenges of parents who also have jobs.

Are scientists blocking their own progress? - The Washington Post - 1 views

  • Max Planck won a Nobel prize for his revolutionary work in quantum mechanics, but it was his interest in the philosophy of science that led to what is now called “Planck’s Principle.” Planck argued that science was an evolving system of thought which changes slowly over time, fueled by the deaths of old ideas. As he wrote in his 1968 autobiography: “A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it.”
  • Is our understanding of the world based in pure objective reason, or are the theories that underpin it shaped by generational biases? Do our most famous thinkers actually block new ideas from gaining ground?
  • A new paper published by the National Bureau of Economic Research suggests that fame does play a significant role in deciding when and whether new scientific ideas can gain traction. When a prominent scientist dies, the paper’s authors found, the number of articles published by his or her collaborators tends to fall “precipitously” in the years following the death — those supporters tend not to continue advocating for a once-famous scientist’s ideas once the scientist is gone.
  • ...8 more annotations...
  • the number of research articles written by other scientists — including those with opposing ideas — increases by 8 percent on average, implying that the work of these scientists had been stifled before, but that after the death of a ubiquitous figure, the field becomes more open to new ideas. The study also found that these new articles are less likely to cite previous research and are more likely to be cited by others in the field. Death signifies a changing of the guard
  • Our instinct is often to view science as a concrete tower, growing ever upward and built upon the immovable foundations of earlier pioneers.  Sir Isaac Newton famously characterized this as “standing on the shoulders of giants.”
  • Mid-20th century philosopher Thomas Kuhn was among the first to come to this conclusion, in his 1962 book “The Structure of Scientific Revolutions.” He argued that scientific theories appeared in punctuated “paradigm shifts,” in which the underlying assumptions of a field are questioned and eventually overthrown
  • Kuhn’s book was, to some extent, a paradigm shift in its own right. According to his logic, commonly held notions in science were bound to change and become outdated. What we believe today will tomorrow be revised, rewritten — and in the most extreme cases ridiculed.
  • the journal Nature earlier this year said scientific data is prone to bias because researchers design experiments and make observations in ways that support hypotheses
  • equally as important are simple shifts in perspective. It only takes one researcher seeing an accepted scientific model in a new light for a solidified paradigm to enter what Kuhn called a “crisis phase” and beg for alternative explanations
  • The NBER study shows that those who questioned consensus ought to be given the opportunity to make their case, not ignored, silenced or pushed to the back of the line.
  • We’re likely to see these “paradigm shifts” happen at a much faster rate as data and research become easier to share worldwide. For some, this reality might seem chaotic; for the truly curious, it is exhilarating. The result may be a more democratic version of science — one in which the progress of ideas doesn’t have to wait until the funeral of a great mind.

How your phone affects your health - Insider - 0 views

  • When was the last time you disinfected your phone? According to a 2017 study, high levels of bacterial contamination can be found on the surface of cell phones.
  • Time magazine suggests that your phone could be 10 times dirtier than your toilet seat.
  • Frequently looking down at your phone for extended periods of time puts a strain on your neck
  • ...4 more annotations...
  • All of your devices emit short wavelength light, known as blue light. A Harvard study claimed that exposure to blue light before bed decreases natural melatonin production, a hormone that regulates sleep. The brightness from your phone screen can interrupt your natural circadian rhythm, and cause for shorter REM cycles and overall restless sleep.
  • With a constant influx of information grabbing your attention, it can put pressure on you to have your phone on you at all times to stay informed. Researchers agreed, telling The Chicago Tribune that the possibility of missing something if you don’t keep your phone nearby can induce a feeling of stress and anxiety. 
  • Remember the blue light? The cornea and lens can’t filter it, so the light goes to the back of the eye, which can weaken vision over time.
  • Though social media can be fun entertainment, it can also open up the door for harmful comparison. Being able to keep up to date with someone else’s success (or pitfalls) invites the opportunity for you to compare your life to theirs. That can invoke a feeling of inadequacy and unhappiness, according to Psychology Today

The Power of Positive Thinking: Too Much and Never Enough - The Bulwark - 1 views

  • Peale was exceptional for cutting the flock some spiritual slack, encouraging them to look for the sunny side and conquer their inferiority complexes. In his world, you can have the economic gains minus the guilt, which seems perfectly suited to the American sensibility.
  • The book sold millions of copies and was eventually translated into more than 40 languages, and Peale, from his pulpit at Marble Collegiate Church in Manhattan, became central to the spiritual life of the family of Fred Trump Sr., his wife, Mary, and the four Trump children, including the future president.
  • it was also well suited to justifying and exacerbating the pathologies of the Trump family and businesses
  • ...12 more annotations...
  • Mary Trump (the president’s niece who also happens to have a Ph.D. in psychology) paints a portrait of Fred Trump Sr. as a sociopath, utterly uninterested in entering into the moral, emotional, and psychological world of his family or its members. In keeping with Peale’s teaching, he would no more hear about his wife’s or children’s problems than he would accept a failed business deal
  • Fred would just say, “Everything’s great, right Toots?” refusing to acknowledge, much less accommodate, her illness. 
  • Fred Jr. was then further abused, repeatedly denied authority, second-guessed at every turn, and blamed for every problem, setback, and failure in a perverse tag-team between Fred Sr. and Donald. The abuse fed his alcoholism, which, in the family’s Peale-informed understanding, was not a disease requiring treatment but the result of Fred Jr.’s negative thinking
  • Peale wanted people to be hopeful, kind, and optimistic, and to become “people persons.” The Trump family heard the positive thinking, personal empowerment parts, which integrated easily with its win-at-all-cost ideology, but they, or at least Donald, missed the bits about seeking counsel from others and living a life of dependence upon God.
  • These are the problem-solving strategies that Donald Trump brought to his marriages, six corporate bankruptcies, presidential campaign, and now, what increasingly appears to be a failed presidency.
  • The consistent element in each of these has been to deny negative realities and keep moving. The casinos, the airline, the football league, Trump Vodka, Trump Steaks, Trump University . . . all bear the same markings of hyper optimism and overpromise/underdeliver salesmanship
  • Trump’s just doing what he’s always done: conquering the challenge by blinding himself to it, just the way Reverend Peale taught him and his father insisted upon. 
  • My AEI colleague, Brad Wilcox, documented that men who identified as “evangelical” but infrequently attend church were more likely to engage in domestic violence than evangelicals who regularly attended church, mainline Protestants and those who never attend church. Wilcox believes this results from a kind of doctrinal cherry-picking—big on authority, sovereignty, and power but closed to other-directed teachings like altruism and self-sacrifice. Weak attachment to religious faith tends to put some of the worst behaviors on steroids.  
  • Fred Jr.’s deepening alcoholism only elicited increasing abuse from his father and brother seemingly under the theory that if they were hard enough on him he would turn around. Even in his final crisis, afflicted by fatal, alcohol-induced cardiac problems, no member of the family went with him to the hospital (Donald Trump went to a movie instead). Dying, it appears, is the result of late-stage negative thought.
  • “prosperity gospel” (a belief popularized by televangelists that God intends Christians to be healthy and wealthy)
  • The purpose of these psychological and spiritual practices is to free individuals from self-doubt and feelings of inferiority and help them to become the people God truly intends them to be: happy, wealthy, popular, and professionally successful.
  • Now we have Trump COVID-19 and it’s following the same pattern. The virus is “very well under control” and “going to fade away.”

Looking inward in an era of 'fake news': Addressing cognitive bias | YLAI Network - 0 views

  • In an era when everyone seems eager to point out instances of “fake news,” it is easy to forget that knowing how we make sense of the news is as important as knowing how to spot incorrect or biased content
  • While the ability to analyze the credibility of a source and the veracity of its content remains an essential and often-discussed aspect of news literacy, it is equally important to understand how we as news consumers engage with and react to the information we find online, in our feeds, and on our apps
  • People process information they receive from the news in the same way they process all information around them — in the shortest, quickest way possible
  • ...11 more annotations...
  • When we consider how we engage with the news, some shortcuts we may want to pay close attention to, and reflect carefully on, are cognitive biases.
  • In fact, without these heuristics, it would be impossible for us to process all the information we receive daily. However, the use of these shortcuts can lead to “blind spots,” or unintentional ways we respond to information that can have negative consequences for how we engage with, digest, and share the information we encounter
  • These shortcuts, also called heuristics, streamline our problem-solving process and help us make relatively quick decisions.
  • Confirmation bias is the tendency to seek out and value information that confirms our pre-existing beliefs while discarding information that proves our ideas wrong.
  • Cognitive biases are best described as glitches in how we process information
  • Echo chamber effect refers to a situation in which we are primarily exposed to information, people, events, and ideas that already align with our point of view.
  • Anchoring bias, also known as “anchoring,” refers to people’s tendency to consider the first piece of information they receive about a topic as the most reliable
  • The framing effect is what happens when we make decisions based on how information is presented or discussed, rather than its actual substance.
  • Fluency heuristic occurs when a piece of information is deemed more valuable because it is easier to process or recall
  • Everyone operates under one or more cognitive biases. So, when searching for and reading the news (or other information), it is important to be aware of how these biases might shape how we make sense of this information.
  • In conclusion, we may not be able to control the content of the news — whether it is fake, reliable, or somewhere in between — but we can learn to be aware of how we respond to it and adjust our evaluations of the news accordingly.

9 Subtle Ways Technology Is Making Humanity Worse - 0 views

  • This poor posture can lead not only to back and neck issues but psychological ones as well, including lower self-esteem and mood, decreased assertiveness and productivity, and an increased tendency to recall negative things
  • Intense device usage can exhaust your eyes and cause eye strain, according to the Mayo Clinic, and can lead to symptoms such as headaches, difficulty concentrating, and watery, dry, itchy, burning, sore, or tired eyes. Overuse can also cause blurred or double vision and increased sensitivity to light.
  • Using your devices too much before bedtime can lead to insomnia.
  • ...7 more annotations...
  • Using tech devices is addictive, and it's becoming more and more difficult to disengage with their technology.In fact, the average US adult spends more than 11 hours daily in the digital world
  • These days, we have a world of information at our fingertips via the internet. While this is useful, it does have some drawbacks. Entrepreneur Beth Haggerty said she finds that it "limits pure creative thought, at times, because we are developing habits to Google everything to quickly find an answer."
  • Technology can have a negative impact on relationships, particularly when it affects how we communicate.One of the primary issues is that misunderstandings are much more likely to occur when communicating via text or email
  • Another social skill that technology is helping to erode is young people's ability to read body language and nuance in face-to-face encounters.
  • young adults who use seven to 11 social media platforms had more than three times the risk of depression and anxiety than those who use two or fewer platforms.
  • Can you imagine doing your job without the help of technology of any kind? What about communicating? Or traveling? Or entertaining yourself?
  • Smartphone slouch. Desk slump. Text neck. Whatever you call it, the way we hold ourselves when we use devices like phones, computers, and tablets isn't healthy.

The FDA Has Approved An Obesity Drug That Helped Some People Drop Weight By 15% : NPR - 0 views

  • Regulators on Friday said a new version of a popular diabetes medicine could be sold as a weight-loss drug in the U.S.
  • In company-funded studies, participants taking Wegovy had average weight loss of 15%, about 34 pounds (15.3 kilograms). Participants lost weight steadily for 16 months before plateauing.
  • "With existing drugs, you're going to get maybe 5% to 10% weight reduction, sometimes not even that,"
  • ...5 more annotations...
  • In the U.S., more than 100 million adults — about 1 in 3 — are obese.
  • Dropping even 5% of one's weight can bring health benefits, such as improved energy, blood pressure, blood sugar and cholesterol levels, but that amount often doesn't satisfy patients who are focused on weight loss
  • The drug carries a potential risk for a type of thyroid tumor, so it shouldn't be taken by people with a personal or family history of certain thyroid and endocrine tumors. Wegovy also has a risk of depression and pancreas inflammation.
  • Like other weight-loss drugs, it's to be used along with exercise, a healthy diet and other steps like keeping a food diary.
  • Wegovy builds on a trend in which makers of relatively new diabetes drugs test them to treat other conditions common in diabetics.

The Fat Trap - NYTimes.com - 1 views

  • While researchers have known for decades that the body undergoes various metabolic and hormonal changes while it’s losing weight, the Australian team detected something new. A full year after significant weight loss, these men and women remained in what could be described as a biologically altered state. Their still-plump bodies were acting as if they were starving and were working overtime to regain the pounds they lost. For instance, a gastric hormone called ghrelin, often dubbed the “hunger hormone,” was about 20 percent higher than at the start of the study. Another hormone associated with suppressing hunger, peptide YY, was also abnormally low. Levels of leptin, a hormone that suppresses hunger and increases metabolism, also remained lower than expected. A cocktail of other hormones associated with hunger and metabolism all remained significantly changed compared to pre-dieting levels. It was almost as if weight loss had put their bodies into a unique metabolic state, a sort of post-dieting syndrome that set them apart from people who hadn’t tried to lose weight in the first place.

The Linguistic Colonialism of English - Brown Political Review - 0 views

  • Through centuries of colonialism, neocolonialism, Cold War expansionism, and, most recently, globalization, the West has spread its preferred systems of capitalism, democracy, and moral values.
  • As a result of this, contemporary English is detached from any specific cultural identity; it is a tool which links different societies in an increasingly smaller world.
  • The first population to speak English was the British. About five hundred years ago, between five and seven million people spoke the language; today, about 1.8 billion people do.
  • ...11 more annotations...
  • Processes of violent imperialism have paved the way for the cultural pandemic originating in the West
  • Most former British colonies now use English as their official language (e.g. Ghana and South Africa). Ever since the US colonized Puerto Rico after winning the Spanish-American war (note the absence of Puerto Rico, or Cuba, in the name of the war), the official languages on the island became Spanish and, of course, English.
  • Today, English is the third most spoken language in the world and tops the list of second languages. English is a necessity for studying at the most prestigious institutions of higher learning, a ticket to working almost anywhere in the world, and an instrument enabling a livelihood in the wealthiest nations.
  • This phenomenon feeds into the growth of social inequality linked to globalization. The majority of the time, English learned as a second language in public schools does not create a proficiency level adequate for working, studying, or relying on the language in daily life.
  • People dedicate their time and resources to learning and perfecting their understanding and knowledge of English, rather than preserving their own customs and culture.
  • The process of globalization leads people to visualize an array of opportunities and an exponentially better future linked to the English language. A language is not only an instrument of communication, however. It is also the tool of a society, made up of its culture, traditions, and sets of religious and ideological beliefs
  • English has also become the main language used in science. Doctors around the world use English to communicate their findings. Most research papers are written in English as a way to facilitate international scientific cooperation.
  • Although this may seem like a necessity to promote scientific discovery, the resulting gap is problematic. The researchers who have not had the chance to learn English are at a disadvantage.
  • These processes suggest a disconcerting implication – globalization is simply a more “socially acceptable” means of imperialism, without violence
  • Globalization and the expansion of the English language have resulted in oppression and inequality.
  • If the preservation of other cultures is given the same importance and value as spreading English is currently receiving, the language can be an addition, not a replacement, to a naturally evolving culture’s array of nuances.

Read this if you want to be happy in 2014 - The Washington Post - 2 views

  • people usually experience the sensation of happiness whenever they have both health and freedom. It’s a simple formula: Happiness = Health + Freedom
  • I’m talking about the everyday freedom of being able to do what you want when you want to do it, at work and elsewhere. For happiness, timing is as important as the thing you’re doing
  • Matching your mood to your activity is a baseline requirement for happiness

  • The good news is that timing is relatively controllable, especially in the long run.
  • If you’re just starting out in your career, it won’t be easy to find a job that gives you a flexible schedule. The best approach is a strategy of moving toward more flexibility over the course of your life.
  • There isn’t one formula for finding schedule flexibility. Just make sure all of your important decisions are consistent with an end game of a more flexible schedule. Otherwise you are shutting yourself off from the most accessible lever for happiness — timing.
  • if you knew that pasta is far lower on the glycemic index than a white potato, you would make a far healthier choice that requires no willpower at all. All it took was knowledge.
  • The most important thing to know about staying fit is this: If it takes willpower, you’re doing it wrong. Anything that requires willpower is unsustainable in the long run.
  • studies show that using willpower in one area diminishes how much willpower you have in reserve for other areas. You need to get willpower out of the system
  • My observation is that you can usually replace willpower with knowledge.
  • the trick for avoiding unhealthy foods is to make sure you always have access to healthy options that you enjoy eating. Your knowledge of this trick, assuming you use it, makes willpower far less necessary.
  • don’t give up too much income potential just to get a flexible schedule. There’s no point in having a flexible schedule if you can’t afford to do anything.
  • the fittest people have systems, not goals, unless they are training for something specific. A sensible system is to continuously learn more about the science of diet and the methods for making healthy food taste great. With that system, weight management will feel automatic. Goals aren’t needed.

  • Did you know that eating peanuts is a great way to suppress appetite?
  • Did you know that eating mostly protein instead of simple carbs for lunch will help you avoid the afternoon energy slump?
  • Cheese adds calories, but the fat content will help suppress your appetite, so you probably come out ahead. If you didn’t already know that, you might end up using willpower to avoid cheese at dinner and willpower again later that night to resist snacking. A little knowledge replaces a lot of willpower.
  • Did you know that exercise has only a small impact on your weight?
  • after I started noticing how drained and useless I felt after eating simple carbs, french fries became easy to resist.
  • I also learned that I can remove problem foods from my diet if I target them for extinction one at a time. It was easy to stop eating three large Snickers every day (which I was doing) when I realized I could eat anything else I wanted whenever I wanted
  • If you’re on a diet, you’re probably trying to avoid certain types of food, but you’re also trying to limit your portions. Instead of waging war on two fronts, try allowing yourself to eat as much as you want of anything that is healthy.
  • healthier food is almost self-regulating in the sense that you don’t have an insatiable desire to keep eating it the way you might with junk food. With healthy food, you tend to stop when you feel full
  • One of the biggest obstacles to healthy eating is the impression that healthy food generally tastes like cardboard. So consider making it a lifelong system to learn how to season and prepare healthy foods

  • I’m about to share with you the simplest and potentially most effective exercise plan in the world. Here it is: Be active every day.
  • When you’re active, and you don’t overdo it, you’ll find yourself in a good mood afterward. That reward becomes addictive over time.
  • After a few months of being moderately active every day, you’ll discover that it is harder to sit and do nothing than it is to get up and do something. That’s the frame of mind you want. You want exercise to become a habit with a reward so it evolves into a useful addiction
  • the intensity of your workout has a surprisingly small impact on your weight unless you’re running half-marathons every week. If your diet is right, moderate exercise is all you need.
  • When your body is feeling good, and you have some flexibility in your schedule, you’ll find that the petty annoyances that plague your life become nothing but background noise. And that’s a great launch pad for happiness.
  • As you find yourself getting healthier and happier, the people in your life will view you differently too. Healthy-looking people generally earn more money, get more offers and enjoy a better social life. All of that will help your happiness.
  • Keep in mind that happiness is a directional phenomenon. We feel happy when things are moving in the right direction no matter where we are at the moment.

The Legacy of Karl Marx: Or, the Inheritance We Dare Not Squander - Unpublished Manuscr... - 0 views

  • That led him to ask the right questions. First: how does free enterprise capitalism work in practice? Second: what is the relationship between economic power and government policy? Third: what is the interrelationship between such economic power and the life of the mind - otherwise known as education and the more general public awareness and perception of reality? Fourth: what questions do and do not get asked within a capitalist society? Fifth: what will be the nature of the next new system?
  • To honor his commitment to the dialectical process, I will offer relatively short commentaries on those questions so that we will have time to engage each other in dialogue. One. Marx built upon the foundation laid by Adam Smith, Thomas Malthus, and David Ricardo; but he transcended their explanation of the capitalist process
  • Two. Marx once called the government of capitalist political economies little more than the executive committee of the high bourgeoisie.
  • ...8 more annotations...
  • Three. Marx has often been criticized for oversimplifying the relationship between what he called the economic base and the intellectual superstructure. There is some truth to the charge, but it is largely a case of misplaced concreteness. He was quite aware that ideas influence the relations of production, as witness his comments about various reform movements. But he was primarily concerned with attacking the proposition that ideas had an ethereal and independent origin, and lived a self-contained existence
  • Four. Two questions take precedence under capitalism: how to turn a short-term profit, and how to keep the system from generating the very opposition that Marx predicted. Those two imperatives have so limited and inhibited the life of the mind, let alone the quality of life, that they amount to a denial of the human spirit. Let us agree that Adam Smith was correct in arguing that entrepreneurial capitalism freed human beings from the constraints of medieval and mercantilist cultures. We must also insist that Marx was correct in explaining how corporate capitalism forged new fetters.
  • Five. There is much in Lenin's thought and practice that I disagree with, but he understood at least one essential element of Marx's thought. Marx realized that capitalism increasingly defined human beings by their function in the marketplace - and so demeaned and stunted their lives, turning them inwards upon themselves as possessors of trivia.
  • permit me my summary of Marx's legacy. First, the weaknesses. I have mentioned some of those in passing, so here I will concentrate on the major items.
  • First, Marx never broke free of the capitalist conception of time defined as short-run success
  • On balance, however, the strengths of Marx outweigh his weaknesses. We can begin with his detailed, tough and persistent inquiry into the dynamics of capitalism that produced a strategy of intellectual inquiry that has provided a sustained tradition of exciting and consequential scholarship in almost every field of knowledge.
  • Then we must salute Marx's deep commitment to the proposition that, since human beings make their own history, we can devise and create a more human and equitable life as members of a community. We can change the world. That is indeed the ultimate purpose of knowledge - to change the world for the better.
  • Next we must acknowledge that the people who have acted on those Marxian contributions have indeed improved the lives of millions of non- and even anti-Marxists

Weight Gain and Stress Eating Are Downside of Pandemic Life - The New York Times - 0 views

  • Yes, Many of Us Are Stress-Eating and Gaining Weight in the Pandemic
  • A global study confirms that during the pandemic, many of us ate more junk food, exercised less, were more anxious and got less sleep.
  • Not long ago, Stephen Loy had a lot of healthy habits. He went to exercise classes three or four times a week, cooked nutritious dinners for his family, and snacked on healthy foods like hummus and bell peppers.
  • ...20 more annotations...
  • But that all changed when the pandemic struck. During the lockdowns, when he was stuck at home, his anxiety levels went up. He stopped exercising and started stress eating. Gone were the hummus and vegetables; instead, he snacked on cookies, sweets and Lay’s potato chips. He ate more fried foods and ordered takeout from local restaurants.
  • “We were feeding the soul more than feeding the stomach,”
  • “We were making sure to eat things that made us feel better — not just nutritional items.
  • Now a global survey conducted earlier this year confirms what Mr. Loy and many others experienced firsthand: The coronavirus pandemic and resulting lockdowns led to dramatic changes in health behaviors, prompting people around the world to cut back on physical activity and eat more junk foods.
  • While they tended to experience improvements in some aspects of their diets, such as cooking at home more and eating out less, they were also the most likely to report struggling with their weight and mental health.
  • With months to go before a vaccine becomes widely available and we can safely resume our pre-pandemic routines, now might be a good time to assess the healthy habits we may have let slip and to find new ways to be proactive about our physical and mental health.
  • The researchers found that the decline in healthy behaviors during the pandemic and widespread lockdowns was fairly common regardless of geography.
  • Alone
  • “Individuals with obesity were impacted the most — and that’s what we were afraid of,”
  • “They not only started off with higher anxiety levels before the pandemic, but they also had the largest increase in anxiety levels throughout the pandemic.”
  • The pandemic disrupted everyday life, isolated people from friends and family, and spawned an economic crisis, with tens of millions of people losing jobs or finding their incomes sharply reduced.
  • despite snacking on more junk foods, many people showed an increase in their “healthy eating scores,” a measure of their overall diet quality, which includes things like eating more fruits and fewer fried foods.
  • The researchers said that the overall improvements in diet appeared to be driven by the fact that the lockdowns prompted people to cook, bake and prepare more food at home.
  • Other recent surveys have also shown a sharp rise in home cooking and baking this year, with many people saying they are discovering new ingredients and looking for ways to make healthier foods.
  • But social isolation can take a toll on mental wellness, and that was evident in the findings.
  • About 20 percent said that their symptoms, such as experiencing dread and not being able to control or stop their worrying, were severe enough to interfere with their daily activities.
  • Dr. Flanagan said it was perhaps not surprising that people tended to engage in less healthful habits during the pandemic, as so many aspects of health are intertwined.
  • Stress can lead to poor sleep, which can cause people to exercise less, consume more junk foods, and then gain weight, and so on.
  • But she said she hoped that the findings might inspire people to take steps to be more proactive about their health, such as seeking out mental health specialists, prioritizing sleep and finding ways to exercise at home and cook more, in the event of future lockdowns.
  • “Being aware is really the No. 1 thing here.”

Suhas Dara Blogs: "All knowledge depends on the recognition of patterns and anomalies."... - 0 views

  • In the study of TOK in DP-1 (11th grade), I have learnt about the ways of knowing, and two of the areas of knowledge - natural sciences and human sciences. Of all the discussions and explorations done into these areas of knowledge, there can be patterns observed in the methods of experimentation, data collection, data analysis and also assumptions being made when generalizing situations. In some of the above points, human sciences is similar to natural sciences, while in the others, the ideologies and working is different.
  • Natural sciences and human sciences for instance both use experiments as a form of data collection but the methods and outputs are different. Natural scientists have lesser moral values to take care of compared to human scientists such as psychologists. Psychologists are directly dealing with humans and hence need to take more ethical implications into consideration. Secondly, human scientists conduct experiments on a large set of people - not limited to one race or gender unless it is required. Natural scientists do not require survey type data. Here, a single scientist conducts the experiments. Both the types of experiments are empirical based though, direct experimentation is more in natural sciences while human sciences are more observation based. But experiments in human sciences have more unpredictable results due to what is known as the Hawthorne effect. This effect explains that when a particular group comes to know that they are under observation for a experiment or an analysis, they tend to be more productive. These cause errors in results of human science experiments especially the ones of psychology.

How To Use Neuroscience To Improve Your Career - 0 views

  • When someone says they aren’t a morning person, it may be closer to the truth than you think.  "Every person has their own brain profile," Cerf said. We each have a circadian rhythm, or an internal master clock that influences when we wake and sleep.
  • With the help of technology, sensors measuring brain activity can reveal how someone feels when they make choices. “We look at your diary for the entire week. We look at all the choices you made, and you try to tell me which ones you’re happy with and which ones you aren’t.” Then, Cerf compares those responses to brain activity to expose the truth.
  • A major influence on your productivity is sleep. Insomnia leads to the loss of 11.3 days’ worth of productivity each year on average, according to a Harvard research study. Your brain and your body need rest. This is why Cerf stressed that we should unplug entirely when we go on vacation. He even suggested changing your standard auto-reply for work emails to an auto-delete.

'I Wanna Eat You Up!' Why We Go Crazy for Cute | LiveScience - 1 views

  • NEW ORLEANS — Ever reacted to the sight of a cute puppy or darling infant by squealing, "I want to eat you up!"? Or maybe you can't help but want to pinch your grandbaby's adorable cheeks. You're not alone. New research finds that seemingly strange aggressive responses to cuteness are actually the norm.
  • In the study, presented Friday (Jan. 18) here at the annual meeting of the Society for Personality and Social Psychology, researchers found that people watching a slideshow of adorable pictures popped more bubbles on a sheet of bubble wrap than did people viewing funny or neutral pictures.
  • The participants rated the pictures on cuteness and funniness, as well as on how much they felt the pictures made them lose control — for example, if they agreed with statements such as "I can't handle it!" The participants also rated the extent to which the pictures made them "want to say something like 'grr!'" and "want to squeeze something." Sure enough, the cuter the animal, the less control and more desire to "grrr" and squeeze something that people felt. Cute animals produced this feeling significantly more strongly than did funny animals. The funny critters in turn produced the feeling more strongly than did neutral animals, perhaps because the funny animals were perceived as cute, too, Dyer said.
  • ...4 more annotations...
  • yer got interested in what she and her colleagues call "cute aggression" after chatting with a fellow student about how adorable Internet pictures often produce the desire to squish or squeeze the cute critter. All the existing research on cuteness suggests the reaction should be the opposite, she told LiveScience. People should want to treat a cute thing with gentleness and care.
  • That's exactly what happened. The people watching a cute slideshow popped 120 bubbles, on average, compared with 80 for the funny slideshow and just a hair over 100 for the neutral one.
  • It's possible that seeing a wide-eyed baby or roly-poly pup triggers our drive to care for that creature, Dyer said. But since the animal is just a picture, and since even in real life we might not be able to care for the creature as much as we want, this urge may be frustrated, she said. That frustration could lead to aggression.
  • Or the reason might not be specific to cuteness, Dyer said. Many overwhelmingly positive emotions look negative, as when Miss America sobs while receiving her crown. Such high levels of positive emotion may overwhelm people.

  • 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.

In a fourth experiment, another group of participants completed the same task, but there was a delay of 90 milliseconds between when each color square was displayed and when they were asked to select the best match on the color wheel.
  • This tendency to lump colors together could explain why it's so hard to match the color of house paint based on memory alone, the researchers said

Which Type of Exercise Is Best for the Brain? - The New York Times - 1 views

  • Some forms of exercise may be much more effective than others at bulking up the brain, according to a remarkable new study in rats. For the first time, scientists compared head-to-head the neurological impacts of different types of exercise: running, weight training and high-intensity interval training. The surprising results suggest that going hard may not be the best option for long-term brain health.
  • exercise changes the structure and function of the brain. Studies in animals and people have shown that physical activity generally increases brain volume and can reduce the number and size of age-related holes in the brain’s white and gray matter.
  • Exercise also, and perhaps most resonantly, augments adult neurogenesis, which is the creation of new brain cells in an already mature brain. In studies with animals, exercise, in the form of running wheels or treadmills, has been found to double or even triple the number of new neurons that appear afterward in the animals’ hippocampus, a key area of the brain for learning and memory, compared to the brains of animals that remain sedentary. Scientists believe that exercise has similar impacts on the human hippocampus.
  • ...7 more annotations...
  • These past studies of exercise and neurogenesis understandably have focused on distance running. Lab rodents know how to run. But whether other forms of exercise likewise prompt increases in neurogenesis has been unknown and is an issue of increasing interest
  • new study, which was published this month in the Journal of Physiology, researchers at the University of Jyvaskyla in Finland and other institutions gathered a large group of adult male rats. The researchers injected the rats with a substance that marks new brain cells and then set groups of them to an array of different workouts, with one group remaining sedentary to serve as controls.
  • They found very different levels of neurogenesis, depending on how each animal had exercised. Those rats that had jogged on wheels showed robust levels of neurogenesis. Their hippocampal tissue teemed with new neurons, far more than in the brains of the sedentary animals. The greater the distance that a runner had covered during the experiment, the more new cells its brain now contained. There were far fewer new neurons in the brains of the animals that had completed high-intensity interval training. They showed somewhat higher amounts than in the sedentary animals but far less than in the distance runners. And the weight-training rats, although they were much stronger at the end of the experiment than they had been at the start, showed no discernible augmentation of neurogenesis. Their hippocampal tissue looked just like that of the animals that had not exercised at all.
  • “sustained aerobic exercise might be most beneficial for brain health also in humans.”
  • Just why distance running was so much more potent at promoting neurogenesis than the other workouts is not clear, although Dr. Nokia and her colleagues speculate that distance running stimulates the release of a particular substance in the brain known as brain-derived neurotrophic factor that is known to regulate neurogenesis. The more miles an animal runs, the more B.D.N.F. it produces. Weight training, on the other hand, while extremely beneficial for muscular health, has previously been shown to have little effect on the body’s levels of B.D.N.F.
  • As for high-intensity interval training, its potential brain benefits may be undercut by its very intensity, Dr. Nokia said. It is, by intent, much more physiologically draining and stressful than moderate running, and “stress tends to decrease adult hippocampal neurogenesis,” she said.
  • These results do not mean, however, that only running and similar moderate endurance workouts strengthen the brain, Dr. Nokia said. Those activities do seem to prompt the most neurogenesis in the hippocampus. But weight training and high-intensity intervals probably lead to different types of changes elsewhere in the brain. They might, for instance, encourage the creation of additional blood vessels or new connections between brain cells or between different parts of the brain.
