Nobody likes paying taxes (well, maybe some oddballs do, but to each their own), but over the last few years, Corporate America has been enjoying the lightest tax burden in history. That needs to change.

Foresters used to remove dead wood because it was once thought of as unsightly. Today, keeping dead wood on the ground has become a priority in forests around the world.

The lockdown in South Africa made it possible to investigate the changes in second‐year students' performance in the Economics department at the University of Pretoria. In particular, we are interested in assessing what factors predict changes in students' performance after transitioning from face‐to‐face (F2F) to online learning. Our main objectives in answering this study question are to establish what study materials the students were able to access (i.e. slides, recordings, or live sessions) and how students got access to these materials (i.e. the infrastructure they used).

The First Amendment of the US Constitution limits the government—not private entities—from restricting free expression. This is why companies like Facebook and Twitter can moderate content—and also why they could suspend then-President Trump’s accounts during his last weeks in office. While many Americans applauded this move as an appropriate response to the violent Capitol insurrection, unexpected critics emerged in corners of the globe where the American version of free speech is considered, well, weird.

German Chancellor Angela Merkel criticized the move as “problematic,” saying that lawmakers, rather than social media CEOs, should regulate speech—the exact opposite of what the First Amendment allows....

France’s Finance Minister also said he was “shocked” by the decision, which he framed as “social media oligarchy” regulating speech. Leaders outside of Europe criticized the move as well.

Children are human beings, not economic commodities. Our response to the pandemic should not be guided by the gloomy speculations of misguided economists, but young people and those who know them. 

Of course, money matters; it is what gets workers through the door.  But whilst it is usually necessary to get a job done, it is not sufficient to get it done well, at least where contracts and worker supervision are incomplete.

In several other countries, filing your taxes is a lot easier. The government uses data it already has on your income to fill out your taxes. But in the United States, Intuit has spent millions each year lobbying against these simpler systems which would eliminate the need for their services. Tax industry lobbying was how the IRS’s Free File was initially created, with the IRS agreeing to leave it up to those companies.

“People who are actually ranked toward the bottom of the income distribution tend to think they’re ranked higher than they truly are. And those who are ranked toward the top believe they’re ranked lower than they actually are.”

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.

There are 365 days in a year, 366 in a leap year. But if you put 70 people into a room it’s almost certain that two of them will have the same birthday. In fact, if you put just 23 people into a room there’s at least a 50% chance that two of them will have the same birthday.

This is known as the birthday problem, or the birthday paradox. (It’s not an actual paradox, just a surprising and counterintuitive result, like the kidney stone paradox or the false positive paradox.) The math behind it is a little opaque, but one intuitive way of explaining it is that the number of potential combinations of people in these groups is large – 70 people equals 2415 different pairings – and any one of those pairings could be a matching birthday.

In fact, other studies have confirmed that people who are suspicious of climate change often remain stubbornly unmoved by firsthand experience with extreme weather. That may be for two overlapping reasons. First, there’s the myth that any kind of cold weather is incompatible with the overwhelming scientific consensus that current global warming is real and caused by people. The frigid snowstorms gripped Texas and the eastern U.S. about six years to the day after a U.S. senator brought a snowball onto the Senate floor as proof against the reality of global climate change. (Each year since then, the U.S. has suffered at least ten billion-dollar or more climate catastrophes, with a record-setting twenty-two such events in 2020.)

One of the really rampant myths that I deal with on a regular basis is about life expectancy in the medieval period. What gets trotted out, over and over, is the idea that “the average life expectancy in the medieval period was 35, so when you were 32 you were considered an old”. Friends, this is extremely not true, and this myth is also damaging to us now....

To write anyone’s life off as excess or frivolous is, quite frankly, monstrous. Medieval people would not have accepted the death of everyone over a certain age as inevitable or excusable. To say that we should now because of their average life expectancy make no sense, and is nothing short of thinly veiled eugenics. If you feel like relating to life and pandemics this way, then I am afraid you are actually treating people more brutally than they were treated half a millennium ago. Reflect on that and do better.

In 1968, a small group of Black Chicago officers—all relatively new to the department—founded the Afro-American Patrolman’s League. Unlike Black police organizations in other cities, the AAPL wasn’t primarily concerned with the officers’ own working conditions. They saw their mission as fighting racist policing from inside the department....

Not surprisingly, the police department did not take AAPL’s actions well. Its leaders were falsely accused of crimes, suspended, and given humiliating assignments. Fellow cops targeted the family of one league leader, Renault Robinson. They called the elementary school where his six- and seven-year-old boys were enrolled, threatening to murder them. The FBI also surveilled the AAPL, building a dossier of more than 500 pages by the end of 1968.

It was in this climate that Child struggled to get back into mainstream publishing. Her next major work was a collection of her columns from the National Anti-Slavery Standard, written between 1841 and 1843. The original abolitionist columns, however, were “too radical for the uncommitted public.”...

As Karcher notes, government censorship, while not unknown, has been fairly rare in America. But there has long been what she calls “censorship American style.” This is a varying mix of market forces—what the public will buy, or what gatekeepers think the public will buy—and conformist opinion about legitimate topics for discussion. Ostracized by “respectable” opinion and threatened by violent anti-abolitionists, Lydia Maria Child felt she had to censor herself to get her message out to a wider audience.

For several decades in the middle of the 20th century, nuts and its facetious cousin nerts were deemed so inappropriate that they were forbidden—along with, but not limited to, whore, SOB, damn, hell,  fanny, and slut—in the scripts of Hollywood movies.

“In popular mythology, the American West stands as a kind of ultimate free labor landscape,” continues Smith, but the reality of indentured servitude, contract labor, and debt peonage, as well as the persistence of chattel slavery, “fits uneasily within familiar narratives of western history.”

If I were asked to give a succinct description of my work (for that, believe it or not, is what writing four or five days a week is) I would say that I am an entertainer and that journalism is simply a form of mass entertainment, like Hollywood or Major League Baseball, albeit one with somewhat lower average earnings potential....

To repeat a suggestion I made on Twitter, I contend that text-based websites should not exceed in size the major works of Russian literature.

This is a generous yardstick. I could have picked French literature, full of slim little books, but I intentionally went with Russian novels and their reputation for ponderousness.

“Today’s interim report from the UNFCCC is a red alert for our planet. It shows governments are nowhere close to the level of ambition needed to limit climate change to 1.5 degrees and meet the goals of the Paris Agreement”, Secretary-General António Guterres said on the report’s findings. 

My home computer in 1998 had a 56K modem connected to our telephone line; we were allowed a maximum of thirty minutes of computer usage a day, because my parents — quite reasonably — did not want to have their telephone shut off for an evening at a time. I remember webpages loading slowly: ten to twenty seconds for a basic news article....

So, with an internet connection faster than I could have thought possible in the late 1990s, what’s the score now? A story at the Hill took over nine seconds to load; at Politico, seventeen seconds; at CNN, over thirty seconds. This is the bullshit web....

An honest web is one in which the overwhelming majority of the code and assets downloaded to a user’s computer are used in a page’s visual presentation, with nearly all the remainder used to define the semantic structure and associated metadata on the page. Bullshit — in the form of CPU-sucking surveillance, unnecessarily-interruptive elements, and behaviours that nobody responsible for a website would themselves find appealing as a visitor — is unwelcome and intolerable.

“Yeah, they may be effective 95 percent of the time, but what about the experience of being inoculated against the century’s first pandemic?” he continued. “We’re people, not zombie consumers. Each dose should be personalized and special.”

But as John Warner points out in his new polemic Sustainable. Resilient. Free. The Future of Public Higher Education, no-cost public college is neither utopian nor new. Rather, narratives that say college should be expensive, that you should take out debt to pay for it if you don’t have family funding, that it is a private investment in your future, are the historically recent developments.

Harvard researchers estimate it would take about $79 billion per year to make all public colleges and universities free; by contrast, our present debt-leveraged, tuition-dependent Rube Goldberg machine that “subsidizes college attendance” costs the federal government $91 billion every year.

The study team analyzed the effect of education and birth year on differences in memory and verbal fluency among nearly 16,000 participants born between 1930 and 1955. Women had better memory scores overall, which became more significant in the groups born more recently. But in the older birth cohort, women had poorer fluency scores than men. That difference progressively reversed in the groups born later, reported Mikaela Bloomberg, a Ph.D. candidate from University College London. 

The religious basis of the act was explicit: the act stated its intention was to thwart “ye old deluder, Satan” in his goal “to keepe men from the knowledge of ye Scriptures.” To this end, the law required every town with 50 or more families to hire and maintain a teacher to instruct all children in reading and writing.

The first paper, which garnered widespread media coverage, found little evidence that COVID had spread in 17 schools in rural Wisconsin that opened buildings with strict safety procedures.

The other study, which has drawn less attention, found that across Wisconsin as a whole, 5,700 COVID cases were linked to outbreaks in K-12 schools and childcare facilities last fall.

Epidemiologist Theresa Chapple worries that studies that rely on contact tracing all have the same flaw — the lack of systematic “surveillance” testing that would provide a complete picture of virus cases in a school.

In the mid-nineteenth century, cities often had the power to lock kids up in reform schools, against their own and their parents’ objections, without convicting them of any crime. This fell under the general legal precept that “the welfare of the people is the supreme law.”

Secondary market trading is societally unproductive (more on that shortly) and should be discouraged by increasing transaction costs (this is one of the big reasons to push for a financial transactions tax, not for revenue purposes, although that’s a nice side bennie, but to shrink the financial casinos).

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.”

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.

“A rooster sits on the apex of a barn roof. The roof pitches at an angle of 43 degrees above the horizontal and is made of wood painted red. On the northern side of the roof, there is a large tree which casts a shadow over most of the roof. On the southern side, there is a duck pond. There is a very light rain shower falling, and the wind speed is 20 km/h from the Southwest. It is 10:47am on the 19th of August and the current temperature is 14 degrees celsius. The rooster lays an egg. Which way does it roll?”

The correct answer to this puzzle is usually given as: “Roosters don’t lay eggs.”

But his greatest legacy was his calculations for pi.

Libraries are still just about the only place in America anyone can go and sit and use a computer and the internet without buying anything. All over the country, library closures during the pandemic have highlighted just how many people have no dependable source of internet on their own.

As I’ve written in the recent past, I believe that the current political uprising has a chance at being an enormously positive development. I worry though that it will be limited by the power of political Calvinism.

I know I’ve heard the term used before, though I can’t remember from who. By political Calvinism I mean the tendency within the left to see the structural injustices of the world as inherent and immutable, so baked into the cake of the current context, history, the United States of America, etc., that they will always exist. The stain of injustice can never be rubbed out. This is most obvious when discussing racial dynamics. White people are inherently in possession of white privilege, as many will tell you – most insistently white liberals, in my experience. Well, yes, today all white people enjoy white privilege, though the valence of that advantage varies with other factors in their lives. But the degree and intensity and in fact existence of white privilege is mutable; if we had a real racial awakening and all people worked to end white privilege, it would end. And not only do I not think this is a crazy thing to believe, I think believing it is a necessary precondition to being an agent of positive change!

During the four-way race for President in 1860, the six-year-old Republican Party found support from a new generation of voters who helped push Abraham Lincoln to victory. They were known as the “Wide Awakes,” because of their youth, enthusiasm, and torch-lit nighttime marches. “Now the old men are folding their arms and going to sleep,” said William H. Seward while campaigning for Lincoln, “and the young men are Wide Awake.”

The only polling in 1860 was the actual voting. Turnout was 81.2% of those eligible to vote (a cohort that consisted only of white men). That’s the the second highest turnout in our history, after the election of 1876. The highest turnout of the twenty-first century so far has been 58.2%, in 2008.

And, at least until recently, SROs were hugely popular. In a 2018 poll, Starr writes, 80 percent of parents favored posting armed police officers at their child’s school. That made superintendents like him cautious about airing “even the mildest criticism” of SROs,” he writes. “Privately, though, many district leaders will tell you that if they had a choice, they’d rather not have armed officers in the schools at all.”

It seems paradoxical at first. While people do escape to cheery landscapes, like the farm of Nintendo’s Animal Crossing, they also spend their money on games engineered to inspire terror, fear, and anxiety. Doom Eternal, Nioh, and Resident Evil all saw high download numbers in the last few months.

What’s the appeal? In the journal Preternature, authors Robert M. Geraci, Nat Recine, and Samantha Fox make a compelling case that video games like these have a meaningful psychological role, especially today. “Faced with physical and psychological dangers, human beings imagine them as monsters and seek to master them,” they explain.

“The horrific experience of videogames, and hence their cathartic appeal, emerges when a game produces a constant level of anxiety in players while allowing the players to act on it,” the authors explain.

Gloves, masks, and other personal protective equipment (PPE) are key to keeping us safe, especially as we began to ease the lockdown rules.

Heroism by the many or the repeated heroism by occupant after occupant of a given role indicates the failure of the surrounding system. Adequate supplies, for example, or prompt pre-emptive action would have changed the effort required of many health care providers from heroic to merely demanding. In that sense, the accolades, deeply deserved as they are, can serve to divert our attention from the less glamorous, indeed the mundane work of repairing the systems so that heroes need not show up en masse to hold together a wheezing and crippled health care system.

Vavilov hypothesized that farmers never intentionally tried to domesticate the rye plant. Ancient weeding methods were based on visual cues—if something looked like a weed, it was plucked. Farmers spent generations unintentionally selecting for rye plants that looked like useful wheat, not weeds. Eventually, rye mimicked wheat so successfully, the two became almost indistinguishable.

The pants allegedly disappeared in 2005. Whenever the business offered to settle, Pearson moved the goalposts, saying he remained unsatisfied. His demands continued to escalate, and he also offered a ridiculous theory of the damages he sought under the D.C. consumer-protection statute. By April 2007, he was demanding over $65 million to settle a claim for a pair of missing pants. The case went to trial, and he lost. He appealed and lost. He sought en banc review and lost. That was, at least, the end of the litigation against the dry cleaners. But Pearson wasn’t done. After losing his ALJ job—some believed the litigation showed poor judgment, you see—he sued for wrongful termination, still insisting he had been in the right. He lost. He appealed, and lost.

Turns out that if you persist in making the same frivolous arguments for a sufficient number of years, the bar association may take notice. In 2015, the D.C. Office of Disciplinary Counsel filed ethics charges against Pearson, which, of course, he furiously contested on the grounds that he had been right all along. He lost. And, of course, he appealed....

With a background in indexing, I like to compare the index of a book with the taxonomy-enhanced search capabilities of a website, whereas the table of contents of a book is like the navigation scheme. A table of contents or navigation scheme is a higher-level, pre-defined structure of content, that guides users to the general organization of content and tasks. It helps users understand the scope of the content available, provides guidance on where and what content to find, and aids in exploration. An index or search feature, including faceted search, on the other hand, enables to user to find specific information or content items of interest. A taxonomy, regardless of its display type, serves the function of an index, not the table of contents.

With several universities now coming to grips with the fact that they will still be online in the Summer (and most likely the Fall), several are turning to how to quickly train their entire faculty in online teaching in a hurry.

Out of all the different ways to approach learning theory, I like focus on power dynamics first when it comes to designing a course. So think about the overall power dynamic you want to see happening in your course. This can change from week to week, but in general most courses stick to one for the most part. The question is: who determines what learners will learn in your course, and who directs how it is learned?

This is such a strange and necessary time to talk about education technology, to take a class about education technology, to get a degree in education technology because what, in the past, was so often framed as optional or aspirational is now compulsory — and compulsory under some of the worst possible circumstances

One of the reasons that I am less than sanguine about most education technology is because I don't consider it this autonomous, context-free entity. Ed-tech is not a tool that exists only in the service of improving teaching and learning, although that's very much how it gets talked about. There's much more to think about than the pedagogy too, than whether ed-tech makes that better or worse or about the same just more expensive. Pedagogy doesn't occur in a vacuum. It has an institutional history; pedagogies have politics. Tools have politics. They have histories. They're developed and funded and adopted and rejected for a variety of reasons other than "what works." Even the notion of "what works" should prompt us to ask all sorts of questions about "for whom," "in what way," and "why."

Surveillance is not prevalent simply because that's the technology that's being sold to schools. Rather, in many ways, surveillance reflects the values we have prioritized: control, compulsion, efficiency.

Independent learning is a skill, and like most skills, you need to start slowly and carefully. Suddenly being thrown into ten courses online is not the best way to go. Many will sink, although some will certainly swim. However, experience tells us that graduate, older and lifelong learners all do much better in online learning than undergraduates. Blended learning – a mix of face-to-face and online – though is a very good way to ease gently into online learning. Introducing online or digital learning gradually in first year, supported by face-to-face classes, is a much better strategy.

As the author of a book on opportunity cost, I might be expected to be enthusiastic about the idea that trade-offs are always important in economic and policy choices. This idea is summed up in the acryonymic slogan TANSTAAFL (There Ain’t No Such Thing As A Free Lunch). In fact, however, a crucial section of Economics in Two Lessons is devoted to showing that There Is Such A Thing As A Free Lunch. It is only when all free lunches have been taken off the table that we reach a position described, in the standard jargon, as Pareto-optimal.

To me, this is an example (and there are many right now) of the extent to which the fairness of the legal system may turn less on the words we use in a law than on the discretion of those who have the power to enforce it.

This evolved into an entire subcultural practice, called Grangerization. Hobbyists used printed books as the basis for a multidimensional media project. They pasted prints, as well as pages of text from other books, into the original volume, making connections between related topics.

In some cases, the resulting work smacked of obsessive fandom. One collector expanded a copy of an 1828 biography of Lord Byron from two volumes to five, rebinding the pages to accommodate 184 illustrations and 14 letters and autographs. Another turned a three-volume 1872 biography of Charles Dickens into nine oversized books packed with broadsides for performances, actor portraits, letters, and images taken from illustrated editions of the author’s books.

Grangerization reached its height of popularity in the first half of the nineteenth century. But not everyone saw it as an innovative, creative hobby. The idea of removing pages from one book to create something new infuriated some critics. One called Grangerization a “monstrous practice” of “hungry and rapacious book-collectors.” Another diagnosed its practitioners with “a vehement passion, a furious perturbation to be closely observed and radically treated wherever it appears, for it is a contagious and delirious mania.”

One advantage of today’s digital media is that we can freely copy material without tearing up precious original work. Of course, today’s Grangerizers have their own ethical questions, like plagiarism, to consider.

"The variation being meant as an evident one, accordingly as presenting in pure intuition the possibilities themselves as possibilities, its correlate is an intuitive and apodictic consciousness of something universal. The eidos itself is a beheld or beholdable universal, one that is pure, 'unconditioned,' that is to say according to its own intuition sense, a universal not conditioned by any fact."

A little-known Democratic senator from Missouri rides the public anger, consequently emerging as a national leader. “Their greed knows no limit,” said Harry Truman in February 1942 in talking about military contractors accused of gouging the government at such a critical time.

The public agreed. A Gallup Poll noted that 69 percent of Americans wanted the government to exert controls on the profits earned by contractors during the war.

Private sector partnership in the face of community need is nothing new, and has long been integral in national response and rebuilding. Take, for example, the case of the Waffle House Index.

Waffle Houses are what they sound like: homey diners that dominate the southern part of the United States, serving up staple favorites like pies and iced tea. With that in mind, the index sounds like a whimsical measurement, but it actually refers to a serious, though informal, measurement of a crisis’s severity. The Federal Emergency Management Agency (FEMA) uses the restaurant chain to gauge how badly an area is affected. As a former FEMA official told NPR, “If the Waffle House is open, everything’s good.”
