Transistors Did Not Completely Destroy the Vacuum Tube

(p. D11) . . . , just as nothing quite matches the ambience created by an incandescent bulb dimmed low, nothing quite sounds like a good tube amp. Audiophiles will argue about whether a solid-state or tube amp is superior. However, it’s best to think of tubes as an aesthetic choice–akin to applying a vintage filter to a pristine snapshot.
Tubes are well suited for musical passages that can sound grating over modern equipment–for example, a classical violinist digging into her instrument during a dramatic passage. Although its overall sound may not be as crisp, a good tube amp will take that shrill edge off.
More and more music lovers are downsizing their sound systems these days, and some tube-amp makers are following suit. Miniature models, like the ones shown here, use a combination of tubes and solid-state technology to minimize bulk. A few are also surprisingly affordable and versatile. You can hook them up to pretty much any audio source, like a smartphone, computer or CD player. Then just add a pair of headphones or speakers.

Hunter-Gatherers Use Division of Labor

(p. D4) The division of labor in hunter-gatherer communities is complex and sophisticated, and crucial to their economic success, researchers report.
A paper in the journal Philosophical Transactions B looks at two hunter-gatherer groups: the Tsimane game hunters of lowland Bolivia, and the Jenu Kuruba honey collectors of South India.
“In contrast to the simple cave man view of a hunter-gatherer, we found that it requires a tremendous amount of skill, knowledge and training,” said Paul Hooper, an anthropologist at Emory University and one of the study’s authors.
. . .
When Jenu Kuruba men go in search of honey, Dr. Hooper said, “there’s one man who specializes in making smoke to subdue the bees, another that climbs the trees, and others that act as support staff to lower combs.”

“Racist” Woodrow Wilson Adopted “White Supremacy as Government Policy”

(p. A25) In 1882, soon after graduating from high school, the young John Davis secured a job at the Government Printing Office.

Over a long career, he rose through the ranks from laborer to a position in midlevel management. He supervised an office in which many of his employees were white men. He had a farm in Virginia and a home in Washington. By 1908, he was earning the considerable salary — for an African-American — of $1,400 per year.
But only months after Woodrow Wilson was sworn in as president in 1913, my grandfather was demoted. He was shuttled from department to department in various menial jobs, and eventually became a messenger in the War Department, where he made only $720 a year.
By April 1914, the family farm was auctioned off. John Davis, a self-made black man of achievement and stature in his community at the turn of the 20th century, was, by the end of Wilson’s first term, a broken man. He died in 1928.
Many black men and women suffered similar fates under Wilson. As the historian Eric S. Yellin of the University of Richmond documents in his powerful book “Racism in the Nation’s Service,” my grandfather’s demotion was part of a systematic purge of the federal government; with Wilson’s approval, in a few short years virtually all blacks had been removed from management responsibilities, moved to menial jobs or simply dismissed.
My grandfather died before I was born, but I have learned much about his struggle — and that of other black civil servants in the federal government — from his personnel file.
. . .
Consider a letter he wrote on May 16, 1913, barely a month after his demotion. “The reputation which I have been able to acquire and maintain at considerable sacrifice,” he wrote, “is to me (foolish as it may appear to those in higher stations of life) a source of personal pride, a possession of which I am very jealous and which is possessed at a value in my estimation ranking above the loss of salary — though the last, to a man having a family of small children to rear, is serious enough.”
And the reply he received? His supervisor said, simply, that my grandfather was unable to “properly perform the duties required (he is too slow).” Yet there had never been any indication of this in his personnel file.
Wilson was not just a racist. He believed in white supremacy as government policy, so much so that he reversed decades of racial progress. But we would be wrong to see this as a mere policy change; in doing so, he ruined the lives of countless talented African-Americans and their families.

While Woodrow Wilson Was President of Princeton, “No Blacks Were Admitted”

(p. A1) PRINCETON, N.J. — Few figures loom as large in the life of an Ivy League university as Woodrow Wilson does at Princeton.

. . .
But until posters started appearing around campus in September, one aspect of Wilson’s legacy was seldom discussed: his racist views, and the ways he acted on them as president of the United States.
The posters, put up by a year-old student group called the Black Justice League, featured some of Wilson’s more offensive quotes, including his comment to an African-American leader that “segregation is not humiliating, but a benefit, and ought to be so regarded by you,” and led to a remarkable two days at this genteel (p. A17) campus last week.
. . .
Perhaps best known for leading the United States during World War I and for trying to start the League of Nations, Wilson as president rolled back gains blacks had made since Reconstruction, removing black officials from the federal government and overseeing the segregation of rank-and-file workers.
Raised in the South, he wrote of “a great Ku Klux Klan” that rose up to rid whites of “the intolerable burden of governments sustained by the votes of ignorant Negroes.”
During Wilson’s tenure as president of Princeton, no blacks were admitted — “The whole temper and tradition of the place are such that no Negro has ever applied,” he wrote — though Harvard and Yale had admitted blacks decades earlier. Princeton admitted its first black student in the 1940s.

Bike Helmet Regulations Hurt Health

(p. D1) . . . many cycling advocates have taken a surprising position: They are pushing back against mandatory bike-helmet laws in the U.S. and elsewhere. They say mandatory helmet laws, particularly for adults, make cycling less convenient and seem less safe, thus hindering the larger public-health gains of more people riding bikes.
All-ages helmet laws might actually make cycling more dangerous, some cyclists say, by decreasing ridership. Research shows that the more cyclists there are on the road, the fewer crashes there are. Academics theorize that as drivers become used to seeing bikes on a street, they watch more closely for them.
. . .
Piet de Jong, a professor in the department of applied finance and actuarial studies at Sydney’s Macquarie University, actually calculated the trade-off of mandatory helmet laws. In a 2012 paper in the journal Risk Analysis, he weighed the reduction of head injuries against increased morbidity due to foregone exercise from reduced cycling.
Dr. de Jong concluded that mandatory bike-helmet laws “have a net negative health impact.” That is in part because many people cycle to work or for errands, experts say. People tend to replace that type of cycling not with another physical activity such as a trip to the gym, but with a ride in a car.

Humans Suffered from Plague by at Least 5,000 Years Ago

(p. D4) Historians and microbiologists alike have searched for decades for the origins of plague. Until now, the first clear evidence of Yersinia pestis infection was the Plague of Justinian in the 6th century, which severely weakened the Byzantine Empire.
But in a new study, published on Thursday [Oct. 22, 2015] in the journal Cell, researchers report that the bacterium was infecting people as long as 5,000 years ago.

Only 5% of Gender Pay Differential Is Likely Due to Discrimination

(p. A17) Full-time employment is technically defined as more than 35 hours. This raises an obvious problem: A simple side-by-side comparison of all men and all women includes people who work 35 hours a week, and others who work 45. Men are significantly more likely than women to work longer hours, according to the BLS. And if we compare only people who work 40 hours a week, BLS data show that women then earn on average 90 cents for every dollar earned by men.
Career choice is another factor. Research in 2013 by Anthony Carnevale, a Georgetown University economist, shows that women flock to college majors that lead to lower-paying careers. Of the 10 lowest-paying majors–such as “drama and theater arts” and “counseling psychology”–only one, “theology and religious vocations,” is majority male.
Conversely, of the 10 highest-paying majors–including “mathematics and computer science” and “petroleum engineering”–only one, “pharmacy sciences and administration,” is majority female. Eight of the remaining nine are more than 70% male.
Other factors that account for earnings differences include marriage and children, both of which cause many women to leave the workforce for years. June O’Neill, former director of the Congressional Budget Office, concluded in a 2005 study that “there is no gender gap in wages among men and women with similar family roles.”
. . .
Ms. O’Neill and her husband concluded in their 2012 book, “The Declining Importance of Race and Gender in the Labor Market,” that once all these factors are taken into account, very little of the pay differential between men and women is due to actual discrimination, which is “unlikely to account for a differential of more than 5 percent but may not be present at all.”

Sense of Purpose, Not Greed, Is Reason Multimillionaires Keep Working

(p. 10) I’ve often wondered why the so-called Masters of the Universe, those C.E.O.s with multimillion-dollar monthly paychecks, keep working. Why, once they have earned enough money to live comfortably forever, do they still drag themselves to the office? The easy answer, the one I had always settled on, was greed.
But as I watched the hours slowly drip by in my cubicle, an alternative reason came into view. Without a sense of purpose beyond the rent money, malaise sets in almost immediately. We all need a reason to get up in the morning, preferably one to which we can attach some meaning. It is why people flock to the scene of a natural disaster to rescue and rebuild, why people devote themselves to a cause, no matter how doomed it may be. In the end, it’s the process as much as the reward that nourishes us.

For Movies, Film Option Survives Digital Advance

(p. B1) Faced with the possible extinction of the material that made Hollywood famous, a coalition of studios is close to a deal to keep Eastman Kodak Co. in the business of producing movie film.
The negotiations–secret until now–are expected to result in an arrangement where studios promise to buy a set quantity of film for the next several years, even though most movies and television shows these days are shot on digital video.
Kodak’s new chief executive, Jeff Clarke, said the pact will allow his company to forestall the closure of its Rochester, N.Y., film manufacturing plant, a move that had been under serious consideration. Kodak’s motion-picture film sales have plummeted 96% since 2006, from 12.4 billion linear feet to an estimated 449 million this year. With the exit of competitor Fujifilm Corp. last year, Kodak is the only major company left producing motion-picture film.
. . .
Film and digital video both “are valid choices, but it would be a tragedy if suddenly directors didn’t have the opportunity to shoot on film,” said Mr. Apatow. director of comedies including “Knocked Up” and “The 40 Year-Old Virgin,” speaking from the New York set of his coming movie “Trainwreck,” which he is shooting on film. “There’s a magic to the grain and the color quality that you get with film.”

Price Theory Paradox When Gas Prices Fall

(p. A3) When gas prices fall, Americans reliably do two things that don’t make much sense.
They spend more of the windfall on gasoline than they would if the money came from somewhere else.
And they don’t just buy more gasoline. They switch from regular gas to high-octane.
A new report by the JPMorgan Chase Institute, looking at the impact of lower gas prices on consumer spending, finds the same pattern as earlier studies. The average American would have saved about $41 a month last winter by buying the same gallons and grades. Instead, Americans took home roughly $22 a month. People, in other words, used almost half of the windfall to buy more and fancier gas.
. . .
Professors Hastings and Shapiro showed that households adjusted their gas consumption much more sharply in response to changes in gas prices than in response to equivalent changes in overall income. In the fall of 2008, for example, as gas prices fell amid a broad economic collapse, consumers responded as if the decline of gas prices were the more important event, significantly increasing purchases of premium gas.
Moreover, this behavior was prevalent: 61 percent of the households made at least one irrational gas purchase. People “treat changes in gasoline prices as equivalent to very large changes in income when deciding which grade of gasoline to purchase,” they wrote.
