The idea that education acts as a Matthew Effect that disproportionately benefits those who start with most is an uncomfortable but well-understood phenomenon. Everything we do in schools either widens the advantage gap between the most privileged and least privileged students, or narrows it. This is, I think, a real dichotomy: anything that, on balance, appears net neutral is in fact acting to keep the gap a yawning chasm of inequity.

Leaving a sock on the ground is a manifestation of a concept from physics you may have heard of: entropy. Entropy is a measure of how much energy is lost in a system. If a system loses too much energy, it will disintegrate into chaos. It takes only a little bit of energy to pick up one sock. But if you don’t take care of your yard, let pipes stay clogged and never fix electrical problems, it all adds up to a chaotic home that would take a lot of energy to fix. And that chaos will leach away your time and ability to accomplish other things.

ACP President Jacqueline Fincher, MD, MACP, says the new guidance reflects several years' worth of data that suggest that shorter antibiotic courses for these infections are just as effective as longer courses, and the growing recognition that overly long prescriptions are among the factors driving unnecessary antibiotic use and promoting antibiotic resistance."These are common infections that physicians and other clinicians treat every day," Fincher told CIDRAP News. "This is the low-hanging fruit that we can go ahead and grab and do something about while we look into other things."

Experts warn we are about to enter a new period of flux as the school year ends and more teachers consider whether to leave after another year of heightened stress. That could lead to a small but meaningful uptick in teachers leaving their schools.

“If the economy accelerates with all the government spending, as I anticipate it will, outside-of-teaching opportunities are going to look pretty good, so we may well face some staffing challenges,” said Dan Goldhaber, a leading researcher on teacher quality issues at the University of Washington. But, he emphasized, such challenges likely won’t be felt across the board, but rather in subjects like special education and math and science, as well as in schools with more low-income students and more students of color.

Actual incidents of intentional smallpox infection “may have occurred more frequently than scholars have previously acknowledged.”

Regrettably, the jet pack would never truly take off: Rocket belts were too expensive, not fuel efficient, and had an extremely short flight duration. The military stopped funding the project, and the rocket belt became a novelty.

Briefly, the researchers found a vas deferens between men treated with phosphodiesterase five inhibitors, like Viagra, and those treated with alprostadil.

Public health experts and the CDC agree that if you are vaccinated and in the company of people who aren’t — or if you don’t know their status — you should continue the safeguards of masking and maintaining your distance.

Putting all these developments together, "it is not unreasonable that we might have the capacity to develop a human embryo from fertilization to birth entirely outside the uterus," Paul Tesar, a developmental biologist at Case Western Reserve University School of Medicine, told the Times. "Whether that is appropriate is a question for ethicists, regulators, and society."

Now, real Going Medieval heads know of course that there is no such thing as a chivalric code, and that chivalry in general has absolutely nothing to do with the treatment of women. Luckily, I have already written that for you, so I don’t need to do it again. What I do want to talk about is that while the idea of chivalry and knights on horses coming to the rescue of damsels in distress is made up, actually the comparison of knights to police is not actually so far off.

That is not, however, a good thing.

By 1941, the Russian dandelion, Taraxacum koksaghyz, supplied 30% of the USSR's rubber. During the Second World War, shortages of Havea rubber prompted other countries, including the United States, Britain and Germany, to begin cultivating dandelion rubber. Once the war was over and supplies returned to normal, these countries — including, ultimately, the Soviets — switched back to Hevea tree rubber because it was cheaper.

Giving at scale by the super-wealthy has done little to redistribute wealth from rich to poor, helping perpetuate social inequalities rather than remedying them, while paying considerable dividends to donors in the form of privilege and influence in society and politics, new research shows.

Corporal punishment in state schools in the UK was made illegal in 1986. This is the story about how it was eliminated in one Local Education Authority, Oxfordshire, before that.

My dad became CEO of Oxfordshire in 1978. He was young, and opposed corporal punishment, but knew, as he puts it, that “in a time of cuts, if I went to the politicians and asked them for money for canes they’d ask me how many I wanted, and did I want the luxury versions”. So he didn’t talk to them about corporal punishment.

“The toll of death is simply staggering — worse than I would have predicted,” said Arthur Caplan, founding head of the division of medical ethics at the New York University School of Medicine. “Covid has been nothing short of the worst failure of public policy in modern memory.”...

All other causes of death pale in comparison to the coronavirus death toll. So far, the coronavirus has killed roughly three times as many people as accidents, lung ailments, stroke or Alzheimer’s disease did in 2019. And the coronavirus has outpaced the number of deaths from diabetes, kidney disease, pneumonia and suicide by even larger multiples.

Prosecutors who want to hold police accountable should seek the bird in the hand, not the two in the bush. They should select charges in these cases so that conviction is a real possibility and, therefore, a real constraint on future police behavior. One "guilty" verdict on manslaughter will do more to reshape officers' behavioral calculus than an endless stream of "not guilty" decisions on murder.

Bottom line: Many people don’t like needles, and that could further slow vaccination efforts as winter turns to spring when supplies are expected to multiply and efforts to get the hesitant to sign up for a dose will intensify.

“Fear of needles was one of the barriers that was a significant predictor of people saying, ‘I don’t think I will get this vaccine,’” said Jeanine Guidry, an assistant professor at Virginia Commonwealth University who researches visual communication and conducted a survey of 500 people in July.

Mather had learned about inoculation more than a decade earlier, from an African man named Onesimus, whom he enslaved. When he asked if Onesimus had ever had smallpox, the man showed him a scar on his arm and explained that his community in Africa used infected material from one person to inoculate others against the disease. A few years later, Mather read a report from Turkey describing a similar procedure.

I remember last March, about three days into the shutdown when my Facebook newsfeed was filled with hilarious memes from parents who had been home teaching their children for a few days. The memes praised teachers, joked about suspending their own children, and immediately needing a vacation. As I saw these posts, I laughed along with them but thought to myself “this won’t last long”. And how right I was. People got amnesia and quick.

While all viruses find ways to evade the body’s defenses, a growing field of research suggests that the coronavirus unhinges the immune system more profoundly than previously realized.

A billionth of a century is approximately pi seconds. The diameter of the Earth is roughly half a billion inches. (Incidentally, one millionth of a century is about 52 and a half minutes. This microcentury is apparently the optimal time for a lecture: long enough to get into depth and detail; not so long that people fall asleep.)

In our view, as education researchers who specialize in science education, the learning sciences and educational assessment, we see an abundance of reasons to let states off the hook for testing this year....

Unfortunately, national experts and research findings indicate that high-stakes testing does not live up to its promise. Instead, research has shown serious negative side effects.

One possible piece of evidence for prehistoric mathematics is the Ishango bone. It was dug up by a Belgian geologist in the 1950s in Ishango, in what is today the Democratic Republic of the Congo (near the border with Uganda); the bone had been buried in a volcanic eruption some 20,000 years ago.

Residents of US nursing homes with more than 40% non-white residents died of COVID-19 at 3.3 times the rate of those of those with higher proportions of white residents, a study today in JAMA Network Open shows.

No one talked about it much, but public health professionals were all aware of a potential nightmare scenario when COVID vaccinations started up in bulk. No, not a slew of severe adverse events – the clinical trials made it clear that these were fairly safe interventions. The nightmare scenario – discussed in small groups online and on campus, was this: What if the vaccines reduce the severity of COVID-19, but not the transmissibility?  In other words, what if the vaccine takes someone who would have been sick with COVID-19, isolating, at home, and converts them into an asymptomatic carrier – out in the world, spreading virus like millions of Typhoid Mary’s.

Fortunately, it doesn’t look like this scenario will come to pass.

As the pandemic sends thousands of recovering alcoholics into relapse, hospitals across the country have reported dramatic increases in alcohol-related admissions for critical diseases like alcoholic hepatitis and liver failure.

Alcoholism-related liver disease was a growing problem even before the pandemic, with 15 million people diagnosed with the condition around the country, and with hospitalizations doubling over the past decade.

It is often said that one theory can be driven out only by another; the neoclassicals have a complete theory (though I maintain it is nothing but a circular argument) and we need a better theory to supplant them. I do not agree. I think any other ‘complete theory’ would be only another box of tricks. What we need is a different habit of mind — to eschew fudging, to respect facts and to admit ignorance of what we do not know.

KHN sent queries about reinfection surveillance to all 50 states and the District of Columbia. Of 24 responses, fewer than half provided details about suspected or confirmed reinfection cases. Where officials said they’re actively monitoring for reinfection, they have found far more potential cases than previously anticipated.

There were thousands of Tweets which said exactly what I was going to say. I thought of ‘liking’ them, to show solidarity, but in the end, I thought ‘he’s just a prat who likes the attention, and my kids need a hug’, so I put my phone down

Covid-19’s fierce winter resurgence in California is notable not only for the explosion in overall cases and deaths in the state’s sprawling urban centers. This latest surge spilled across a far greater geographic footprint, scarring remote corners of the state that went largely unscathed for much of 2020.

Interestingly, hundreds of plant species in sand dunes have evolved sticky surfaces, suggesting utility in that habitat. Windblown sand coats these sticky surfaces – a phenomenon known as psammophory, which means “sand-carrying” in Greek. While a sandy coating may limit light from reaching plant surfaces, it also likely protects plants from abrasion and reflects light, reducing leaf temperature. It also defends plants from hungry predators.

Why isn’t it considered bad behavior to sit in front of a wall of screens filled with flashing numbers making bets on those numbers? Would it attract the cultural scolds if the people making those bets were drinking tall boys in brown bags, rather than sipping bespoke lattes?

Read the latest reports concerning Covid-19 and academia and it has become clear that the inequalities and representation of women have worsened. Women are submitting fewer preprints, dropping enrolments in university programmes, missing from pandemic-related scientific committees, and experiencing pressure during lockdown periods to take on traditional caregiving and domestic responsibilities. These are not simply temporary setbacks, but a call to reflect on longstanding social schemas. What this suggest is, that it is time for research that considers a wider array of variables.

“The joy of games like Hitman for me is that they’re presented with an incredibly straight face, but allow you to do incredibly silly things,” he told Polygon over email. “I’ve previously killed 553 people using only a fish in the game, so it just seemed like a natural progression for the freezer challenge.”

A website that claims to sell ad space for Covid-19 vaccinations has triggered both laughter and existential dread, with many expressing despair over the possibility that the absurd gimmick could actually be real.

There is a right way and a wrong way to do a diet study.  The wrong way is to send a survey to a few thousand people asking them to recall what they eat and linking those responses to outcomes down the road. That’s how we get studies that tell us that eggs kills you, or keep you healthy, or something. The right way is to do what the good folks at the NIH did in this study appearing in Nature Medicine – lock people in a room for 28 days and measure absolutely everything.’

To answer that requires explaining the concept of short selling, which most civilians find nearly incomprehensible. A short sale is a bet that a stock (or any other speculative asset, like bonds or gold) is going to decline in price. But to make that bet, you have to sell something you don’t already own, which is not normal behavior. To accomplish this, you have to borrow the stock from somebody who does own it. As with any loan, you have to pay interest on the borrowed asset. And you also have to keep some collateral on deposit with your broker as an assurance you’re good for the money. The hope is that the price will fall, and you can buy the shares — cover the short, in the jargon — at a lower price. Your profit would be the difference between the original sale price and the closing purchase price, minus any interest paid on the borrowed asset.

But what if you’re wrong, and the price rises? Then you’re in trouble. When you buy a stock, your risk is that you could lose the entire purchase price — but no more. With short selling, if you’re wrong, there’s no predetermined limit to how much you can lose if the price keeps rising. And if the price keeps rising, your broker will demand more collateral in the form of real money. You have a choice between giving up — covering the short and taking the loss — or keep pouring more collateral into a losing position in the hope that things will finally turn your way.

But the researchers wanted to know whether there was a reason for the cats to go wild, beyond pure pleasure. That is when one of the scientists heard about the insect-repelling properties of nepetalactone, which about 2 decades ago was shown to be as good as the famed mosquito-stopper DEET. The researchers hypothesized that when felines in the wild rub on catnip or silver vine, they’re essentially applying an insect repellant.

If you were an adherent of the ceiling view, you might reasonably say, look, even if the effect of income on happiness is linear in the log of income, that’s basically the same as saying it’s not linear in income, and that above some threshold or ceiling you’d need to increase your income by a lot in order to see any substantial increase in happiness.

So you can see why an advocate of the threshold or ceiling view of income satisfaction might be unconvinced that the log-linearity of happiness in income is much to be concerned about. Sure, it’s still growing, but after the initial steep increase in happiness that comes with getting some money, across most of the range of achievable incomes the increase is negligible.

Enslavement in the northern states is often glossed with a statement about how the practice was ended in such and such a year. The reality is more complicated. Emancipation was piecemeal, gradual, and, when it came to visitors from other states and even nations, often ambiguous.

I am months overdue for my tests because I lost my job and health insurance in July. I am resigned to paying out of pocket for the tests. (I got this healthcare-only credit card when I got my teeth fixed a couple years ago and I’m planning to use that.) However I have been stymied because the labs I’ve contacted simply will not give me straight answers about how much it will cost.

I have always tried to be someone with an expansive moral imagination – that is, to try and understand the other side’s perspective even when I viscerally reject that perspective. But I cannot understand the mindset of people who defend the current system, or those who preserve it by opposing change even if they will not defend the current system explicitly. I cannot occupy that point of view. The system seems indefensible, and the most likely short-term change to the system will be to make it even worse. All here in America, the world’s shining city on a hill.

In 1919, only 31 percent of 14- to 17-year-olds were enrolled in high school. By 1980, enrollment had reached 90 percent. High school graduation rates rose from 16 percent to 71 percent during this same period. As a result, the school became an avenue through which policymakers could reach the vast majority of U.S. citizens, allowing them to enlist public education in the ideological contest with authoritarianism. By building a model of education that emphasized critical thinking and a humanistic view of individual freedom, U.S. policymakers explicitly tried to eschew educational practices they considered to be “indoctrination,” “propaganda,” or “authoritarian.”

But this approach to education began to change once the threat of authoritarianism seemed to diminish in the 1980s. Educators began to place the needs of the market over the imperative of civic-mindedness. That turn has gradually transformed the role of schools in American life from incubators of democratic citizens to engines of economic aspiration.

American educators first began to discuss the perils of authoritarianism during World War I, with the rise of an aggressive, expansionist Germany under the helm of Prussian Kaiser Wilhelm II. When the United States entered the war against Germany in 1917, U.S. scholars cast “Prussianism” as an authoritarian ideology, and they denounced its centralized approach to schooling and governance; the United States, on the other hand, administered schools locally. Studies of German schools published during the war, such as Victor Friedel’s The German School as War Nursery and Thomas Alexander’s The Prussian Elementary Schools, described how the Prussian schoolmasters had distorted German life and steered German culture toward the imperialistic goals of the state.

As Alexander, a professor of education at the George Peabody College for Teachers (Vanderbilt University), explained in 1918 “the Prussian is to a large measure enslaved through the medium of his school . . . his learning instead of making him his own master, forges the chain by which he is held in servitude.” By contrast, he argued, American education ought to take a more student-centered approach in accordance with “the democratic principles for which we are aiming.”

"A computer as a research and communication instrument could enhance retrieval, obsolesce mass library organization, retrieve the individual's encyclopedic function and flip it into a private line to speedily tailored data of a saleable kind."

McLuhan was not concerned primarily with the upsides of the internet. He warned that surrendering to private manipulation would narrow down the availability of the information we receive based on what marketers and advertisers choose for consumers and voters to see. And nowhere is that more evident than in our addictions to social media platforms and our need to be connected 24/7. 

In the late fifteenth century, Spanish colonizers in the Caribbean were starving in a land of plenty. They had just established their newest settlement, La Isabela, in what is now the Dominican Republic. The Spaniards planned to survive by exploiting the area’s indigenous people, the Taínos. But the Taínos refused to plant their annual crops, in protest of the Spanish invasion and appropriation of their lands.

From the long-lasting impacts of redlining in the US to the falling proportion of female graduates in computer sciences since 1984, the examination of unequal power forces runs as a central theme in the book.

The authors focus on data justice, as opposed to data ethics. They argue that data ethics and its focus on fairness and biases create structures that protect power. A great example of this is the rampant use of artificial intelligence for a ‘fair’ hiring process. As AI pulls from existing datasets (in which white, rich men are overrepresented), it can hamper the chances of women and minority communities getting past resume screenings. Conversely, datasets in which marginalised communities are overrepresented, such as policing or access to government aid, lead to situations where algorithms will predict them to be more of a threat, making it more difficult for these groups to access credit or producing a higher probability of individuals being incarcerated.

Missing from this commentary is the acknowledgement that young people have been found to have a high rate of compliance with regulations. They are also at a particularly high risk of contracting COVID-19 due to things like their over-representation in jobs dealing with customers face to face, and being more likely to reside in shared living spaces and rely on public transport than older adults.

So the suggestion that spikes are entirely due to reckless rule breaking and that young people are the root cause of a second wave of COVID-19 is problematic and unhelpful, particularly when used to justify the implementation of unique measures for students who are effectively living in isolation across Scotland right now.

The seriousness of COVID-19 and the importance of containing it is not in question. But these restrictions have been uniquely and unhelpfully couched in the rhetoric of blame and punishment. This has contributed to an image of young people as reckless and substantial risks to public health, with media coverage of parties in student halls focusing on a minority of rule breakers.

"Right now, the president might be the victim of a well-described medical phenomenon called the VIP syndrome."

If you looked at this treatment regimen, not knowing the patient, you’d assume this was someone on the brink of death – ventilated. Last ditch effort time. Of course, the president does not seem to be particularly sick. So, let’s face it – if you or I had COVID and were as sick as the president, there is no way we would be getting this kind of treatment. And here’s the thing – we’re probably better off.

Look, I’m not going to go hardcore egalitarian here. If we had a magic pill that cured COVID with no side effects, but cost 10 million dollars – sure give it to the president even though the rest of us can’t get it. The unfairness is not really what the VIP syndrome is about. It’s the risk the VIP faces getting medications – and combinations of medications - that we don’t know enough about. Doctors know that standard care is the best care. That’s why it’s standard. The Hail Mary Pass is for the 4th quarter when your team is about to lose. It’s not your opener. But for VIPs, these essential truths get forgotten.

Already, more people live outside of their countries of birth than ever before, and according to the UN’s International Organization for Migration, as many as 200 million people might need to leave their homes for climate-related reasons by 2050.

Despite these projections, no legal framework exists to help such migrants relocate, let alone to protect them in their most vulnerable moments. Instead, governments worldwide have neglected and exploited this new class of “climate displaced”—exposing them to both climate shocks and the abuse that often follows. Governments and international organizations can pursue a better course by enabling vulnerable populations to migrate before and after disaster strikes. The benefits of such a policy far outweigh the short-term costs.

“It might be too late to avert a climate crisis,” says the climate migration expert Jane McAdam, who directs the Kaldor Centre for International Refugee Law at the University of New South Wales. “But we can avert a displacement crisis if we start to act now.” To do so will require casting climate migration in a new light: not as a burden to be repelled but as a shared global reality to collectively manage.

Both battlefields are now under the care of the National Park Service. This past Fourth of July, few people visited either, but when travel becomes easier, if you're within range, I suggest you visit whichever park is closer. Both parks are beautiful, especially in mid-summer. However, do not ask the question several NPS rangers submitted to me as their nomination for the dumbest query ever received from a visitor: "How come they fought so many Civil War battles in parks?" Instead, if you're at Vicksburg, suggest to the ranger that Gettysburg was the more important victory; if at Gettysburg, suggest Vicksburg. Probably you and your fellow tourists will be informed as well as entertained by the response. 

In Gettysburg, don't fail to take in the South Carolina monument. It claims, "Abiding faith in the sacredness of states rights provided their creed here" — a statement true about 1965, when it went up, but false about 1863. After all, in 1860, South Carolinians were perfectly clear about why they were seceding, and "states rights" had nothing to do with it. South Carolina was against states’ rights. South Carolina found no fault with the federal government when it said why it seceded, on Christmas Eve, 1860. On the contrary, its leaders found fault with Northern states and the rights they were trying to assert.

The vaccine trial that Vice President Mike Pence kicked off in Miami on Monday gives the United States the tiniest chance of being ready to vaccinate millions of Americans just before Election Day.

It’s a possibility that fills many public health experts with dread.

For too long, a culture of American exceptionalism has been a barrier to the implementation of policies that have improved public safety around the globe. Now, the United States’ capacity to heal as a nation could very well depend on its willingness to listen and learn from the rest of the world.

In 2014, ProPublica published one of the most comprehensive analyses to date of racial disparities in deadly police encounters. Its examination included detailed accounts of more than 12,000 police homicides between 1980 and 2012, drawn from the FBI’s Supplementary Homicide Reports. During this three-decade period, ProPublica found that young Black men were 21 times as likely to be fatally shot by law enforcement as were their white peers. 

On rare occasions, typically after a city has been embroiled in years of scandal, the federal government and a municipality might enter into a consent decree, which allows the Department of Justice to monitor the activities of a particular agency and shepherd any necessary reforms. Such oversight is considered an exceptional step in the United States; in the safest countries in the world, it is the norm.

“Simpler times” stated Cobargo farmer Keaton Gray (55).

“At least this time we don’t have to palm off handshakes from the Prime Minister and identify our dead cattle by the melted tags on their ears.” 

Learning with myths manifests in many ways. Redundant development to accommodate learning styles, or generations. Shortened to be appropriate for millennials or the attention span of a goldfish. Using video and images for everything because we process images 60K faster. Quiz show templates for knowledge test questions because they’re more engaging. And all of these would be wrong.

Instead, mythless design starts with focusing on performance. That is, there’re clear learning outcomes that will change what people do that will affect the success of the organization. It’s not about knowledge itself, but only in service of achieving better ability to make decisions.

As the United States faces a long, uphill recovery from the COVID-19 pandemic, it would do well to consider a measure that could put its people to work, at a living wage, for the benefit of all. But a job guarantee is not a crisis measure: it must be a permanent policy, because unemployment devastates communities even when economies are relatively strong.

One thousand women on horseback: these were the roving New Deal librarians who, starting in 1935, brought books and set up libraries in some of the most remote areas of Kentucky. The women rode across 29 counties, sometimes more than 100 miles a day. And where the terrain was difficult, they dismounted their horses and carried the books on foot. Their impact was far-reaching. As one recipient put it: “Them books you brought us has saved our lives.”
