Maybe you've seen this graph, which has been making the rounds on social media for the past few days:
It shows that the proportion of women majoring in computer science began to decline in 1984, at the same time that women in other professional and scientific fields continued to increase.
NPR's Planet Money wondered why there was such a difference between the fields of study, and they've come up with the answer. You can listen to it here (it's about 17 minutes long):
Or visit the NPR site to play it.
But the short answer is that 1984 was just a few years after personal computers were becoming common, so by that time, some of the college students studying computer science had, in effect, taken unofficial prerequisite courses in programming. Those were the students who had computers.
The story then addresses why those students were likely to be men. Ads, media portrayals, Radio Shack exclusivity, and gendered family assumptions about who should have the computer all played a part.
Unforturnately, the story doesn't deal with the other aspect of the digital divide, which is income. Middle-class girls were shut out by the unofficial prerequisite, but so were low-income girls and boys, which includes the majority of students of color.
So there's more to the story. But still, worth a listen.

It's too beautiful a fall day to do anything but post a few photos of what it looks like all around me.
Minnesota is having the most colorful fall I can remember. Not sure if it was caused by the relatively even rainfall over the summer or the deep dormancy of our last, extra-long winter, but the trees are at their best and the sun keeps coming out to add highlights.
A ginkgo tree all in yellow.
One of the many sugar maples.
Sweet fern (Comptonia peregrina), which is not a fern, but is native to sandy places here to the East Coast. I had forgotten or never noticed that it turns into this beautiful range of colors. And if you see some of this low shrubby plant, be sure to lean down and rub the leaves with your nose nearby.
A red oak (with orange leaves) and the kind of blue sky Minnesota seems to have all the time lately.

Star Tribune letter writer Owen Hecht of Hastings, Minnesota, brings a reality check to the constant message that President Obama is unpopular and Democrats are running away from him (as in the cartoon from the Strib just a few days ago, in fact).
It seems every day I read about President Obama’s dismal job approval ratings. Here are the lowest approval ratings for the past nine presidents:I assume that Hecht has used the lowest approval ratings of each president. Most of these numbers are not from a mid-term election period (Nixon and Bush 1 are).
Obama: 38 percent, in September 2014.
George W. Bush: 25 percent in October 2008.
Bill Clinton: 37 percent in May 1993.
George H.W. Bush: 29 percent in July 1992.
Ronald Reagan: 35 percent in January 1983.
Jimmy Carter: 28 percent in June 1979.
Gerald Ford: 37 percent in March 1975.
Richard Nixon: 24 percent in August 1974
Lyndon Johnson: 35 percent in 1968.
Obama’s approval ratings this month have been above 40 percent.
And, of course, remember that Congress's approval rating was at 14 percent in September.

It's no secret that I love the writing of Ursula LeGuin. When asked for the title of my favorite book, I have a hard time coming up with anything other than The Dispossessed, even though I first read it when I was 15.
Despite my love of LeGuin, my knowledge of her complete works is less than perfect. I just found out about an essay she wrote in the late 1980s called Introducing Myself, which makes me appreciate her writing even more, if that's possible. In it, she deals with age, gender, and the presentation of the self with such humor that I can't even say anything worth saying about it. Here's one excerpt:
I don’t have a gun and I don’t have even one wife and my sentences tend to go on and on and on, with all this syntax in them. Ernest Hemingway would have died rather than have syntax. Or semicolons. I use a whole lot of half-assed semicolons; there was one of them just now; that was a semicolon after “semicolons,” and another one after “now.”I'm not sure how much of the essay is included on the linked site (Brain Pickings). I guess I'll have to check out a copy of the book of essays where it was published in 2004, The Wave in the Mind.
And another thing. Ernest Hemingway would have died rather than get old. And he did. He shot himself. A short sentence. Anything rather than a long sentence, a life sentence. Death sentences are short and very, very manly. Life sentences aren’t. They go on and on, all full of syntax and qualifying clauses and confusing references and getting old.

Looking through blog post drafts that never made it, I came across these two quotes from 2013 a Psychology Today article:
But there are double standards based on gender. Particularly distressing are the double standards about physical appearance: Peers place an enormous emphasis on attractiveness among affluent girls. Across the board, the more attractive kids— boys or girls, rich or poor—are more likely to be most popular with their peers. But for girls of high socioeconomic status, the onus on being attractive is incredibly high. In our research, we have found that links between peer admiration and beauty were almost twice as strong among affluent girls as compared with affluent boys, and also compared with inner-city girls and boys. Looking "like a scrub" is simply not acceptable for well-off young women.And:
The enormous pressures that girls face from the peer group are matched by the impossibly high demands from adults to succeed in domains that are traditionally male, such as academics and sports, and also in the "feminine" domains of caring and kindness. They must not only be highly accomplished but also polite and likable, and they are expected to master the competing demands without any display of visible effort. Daughters of the rich, therefore, strive for effortless perfection—which is not merely challenging to their well-being but ultimately soul-draining.
Enter envy. My colleagues and I recently found that, compared to inner-city counterparts, students at elite, upper-middle-class schools, especially girls, experienced significantly more envy of peers who they felt surpassed them in popularity, attractiveness, academics, and sports.It reminds me of a recent Pacific Standard article that's been sitting open in my tabs: Savor Extraordinary Experiences, Feel Worse Afterward. "Harvard researchers find painful feelings of social exclusion are the unexpected price one pays for having amazing adventures."
At the same time, the intense push for superachievement deprives affluent adolescents of one of the critical safety valves of life—the deep social connectedness of friendship. The very path they take for success inhibits the development of intimacy. The durability, sustainability, and strength of relationships are constantly threatened by competition for highly sought-after goals. There's only one valedictorian. How can two people be friends if the self-worth of both depends on being the one chosen for a sought-after goal? One's gain is the other's loss.

Another photo from the streets of the Twin Cities:
The side of the truck reads "Jesus Delivers."
And he does it in a truck that looks like it's accustomed to hard work, represented by a font that usually is found on movie posters.
Jesus Delivers, it turns, is a rolling, faith-based food pantry.

In case you've never noticed, in the right sidebar of this blog, just below my queen-of-spades profile picture, there's a spot where I list what I'm currently reading.
This reality has direct implications for the War on Drugs and recent and ongoing killings of black people by police and civilians. Trayvon Martin, Jordan Davis, Mike Brown, John Crawford -- all were assumed to be dangerous and criminal because of what they looked like.
I wanted to read Muhammad's book because it connects with Michelle Alexander's The New Jim Crow, which I've written about before. Muhammad, director of the Schomburg Center for Research on Black Culture, located in Harlem, is a somewhat frequent guest on the Melissa Harris Perry show. I'm always impressed by his ability to make connections in few words.
It's pretty successful. Here are some facts from it that sprang out at me.
The increase in crime rates of the late 1960s and 1970s -- which was the excuse for the rise in incarceration rates and the War on Drugs -- was partly the result of increased reporting by local police agencies, which had received increased federal funding to track statistics. As with the autism rate, it's hard to say how much something has increased if you don't have accurate numbers for the earlier years. (page 26)
Reagan's War on Drugs meant federal money flowed everywhere. Twelve regional drug taskforces were set up with a thousand newly hired agents and prosecutors. (page 41)
A 1983 study by Reagan's justice department found that incarceration "does not appear to achieve large reductions in crime" even though it "can cause enormous increases in the prison population." But policy makers ignored that finding, preferring a flawed 1987 study that found each prisoner saved taxpayers over $400,000. The totality of the Reagan-Bush era, 1980 to 1993, saw a 521 percent increase in corrections spending, while cutting employment and training programs in half. (pages 46 and 47)
Bill Clinton danced along the sword blade of "tough on crime," while making noises about drug treatment and community policing. During the 1992 campaign, he flew home to Little Rock to watch an execution of a "mentally impaired black man, [who] had so little conception of what was happening to him [that] at his last meal" he asked "Can I save my dessert for the morning?" Clinton didn't want to be seen as soft on crime, so too bad for that guy. He was executed.
Alberto Gonzalez, while counsel to George W. Bush as governor of Texas, never showed Bush mitigating evidence or presented a single petition for clemency in a death row case. 152 people were executed in Texas while Bush was governor, more than any governor in 50 years. (page 68)
New York City saw a huge decrease in crime, starting in the 1990s.
Despite this, New York's prison population grew much less than the nation's as a whole, and its jail population actually decreased. The book posits the idea that because the city had spent money stabilizing housing, it reaped the benefit, as compared with Chicago "which let its housing decay, and put its money in law enforcement." (pages 77 and 78)
Now it's time to get back to The Condemnation of Blackness, which supplies the footnotes and proof.

One of my favorite outrageous facts is that Americans spend $6 billion annually on Halloween, roughly the equivalent of all the spending on the 2012 presidential election.
I can't even figure out how that's possible. But then again, we also spend $13 billion on Valentine's Day, so maybe I should forget about Halloween.
Anyway. Here's my idea of what Halloween decorations should look like, which wouldn't add a thing to the annual spending:
Yes, those are plastic milk jugs, connected with string.

I used to post a list of articles from the latest issue of Discover magazine somewhat regularly (such as here, here, and here), but over the past year or even two, it seems as though their stories have been less compelling.
Until the November 2014 issue, which just arrived. There were half-a-dozen noteworthy articles or short entries.
It took a village. New research indicates that early hominid mothers shared baby-wrangling duties, including shared breast-feeding. And that this was a major factor in the increased size of brains as we evolved toward Homo sapiens: babies could be born increasingly unable to take care of themselves for a long period of time, which allowed more brain development to happen after birth. So, in essence, cooperation among females came first, creating what we think of as humans.
Stinking to high heaven. In keeping with the work of social psychologist Jonathan Haidt, researchers recently found that smelling a putrid odor primes people to respond more strongly from disgust when asked about socially controversial issues. They "subsequently expressed dramatically more conservative attitudes about premarital sex, pornography and religion -- including increased belief in Biblical truth -- than those who sniffed an odorless concoction. The topic of same-sex marriage proved especially repugnant to those who had been subjected to the stench." So perhaps all the manure in rural areas contributes to making rural people more conservative... huh. I wonder if this holds up for people who live around chemical plants. What about Gary, Indiana, for instance? The whole place smells revolting.
Bye-bye birdies. Whenever you hear someone say that wind turbines kill birds, remember these two graphs:
Cats kill 2.4 billion birds a year, vs. 234,000 birds a year for wind turbines. That's more than 10,000 times as many. That's why the wind turbines aren't even visible in their spot on this bar graph. It's just too small an amount, relative to the giant killer-cat bar.
So you might say, there aren't that many turbines yet. Doesn't that account for the low absolute numbers? No. Each cat kills almost seven times as many birds as a wind turbine. And our cars and the trucks we depend on for delivering goods kill twice as many as those killer cats, if you compare a mile of road to a single cat.
Conversation's gender gap. I hate the sexist doofery that proclaims women talk more than men, when my experience in mixed groups is that men talk more and don't listen even when the women do talk. A recent study put some numbers to the question by eavesdropping on different types of conversations, and found that "in a laid-back lunchtime atmosphere, men chatted just as much as women; in a cooperative, task-driven environment, women won out -- but only in small groups. Men out-talked their female peers in groups of six or more..."
Trial and error. The most disturbing story of all in the issue was a longer piece describing a crisis in cancer research practices. Lines of cancer cells (like HeLa) are propagated and shared or sold by researchers. So if you want to test a new thyroid cancer treatment, for instance, you need thyroid cancer cells to try out your treatments in a petri dish before you can move to animal or human trials. However, for the past 10 years or so, scientists have begun to realize that the cell lines they were distributing are not the types of cancer they thought they were -- that through contamination or mislabeling, they are other types of cancer, most often melanoma or cervical cancer, which propagate more readily. So all too often, treatments for one kind of cancer were tested on the wrong kind of cells.
Once this type of contamination was recognized as a problem, you'd think that -- being scientists! -- the researchers would come up with a way to fix the problem, but no. Too many people's publications and research careers have been built upon work with a faulty foundation. Systems that would counter the problem -- such as requiring testing of the cell lines to assure they are the correct type of cancer before exposing them to experimental treatments -- for too long were not required for funding or publication. It's only in the last year or so that journals have begun to require this obvious standard before accepting a paper for publication. The NIH still doesn't require it for funding.

I posted back in April about the tax problems of local musician/performer Venus DeMars. In short, DeMars and her wife (a poet) were raked over the coals by the Minnesota Department of Revenue for years because someone in the department thought they weren't really professional artists, and therefore weren't allowed to take tax deductions they had taken.
Happily, they were finally vindicated back in May of this year.
I wondered at the time what the law or policy was at the federal level, though, and today's newspaper delivered the answer, in the form of a New York Times article about the case of painter and printmaker Susan Crile. Crile teaches full-time at Hunter College in the studio art department, a position that requires her to show art, but not sell it. Her work is in the collection of the Met, the Guggenheim, and other major museums.
She has been an artist for 40 years, including at least 10 before she joined Hunter part-time and 20 years before she was tenured. She has grossed close to $700,000 from art during her career, but only made a profit in three years. The types of expenses she has claimed include art materials and food and travel expenses related to showing her work.
The IRS wanted $81,000 in back taxes for the years 2004 to 2009. They cited her lack of a business plan as evidence that her art is not a business. (!!!) They declared that her claim to be an artist and a teacher was "artificial." Her expenses, the agency said, "should have been filed not as business expenses but as unreimbursed employee expenses."
The case was just decided in the U.S. Tax Court by Judge Albert G. Lauber. He ruled that Crile had "'met her burden of proving that in carrying on her activity as an artist, she had an actual and honest objective of making a profit' and therefore under tax law should be considered a professional artist."
The story ends with these paragraphs:
Robert Storr, dean of the Yale School of Art, who testified on Ms. Crile’s behalf, said Monday that the ability to deduct art-related expenses — in art careers that might generate little money — was “one of the last remaining areas where the federal government cuts artists any slack to allow them to do what they do,” and that its protection was crucial.I'm generally pretty supportive of the IRS and its mission. I believe in paying taxes for the common good. I think they get used as a political strawman way too often.
Micaela McMurrough, a lawyer... who represented Ms. Crile, said one of the key points argued in the case was that “art is not a business like other businesses.” “And I think that’s what this decision reflects, to a large extent,” she said....
Ms. Crile said she was relieved by the decision, for herself but also for many other creative professionals it might affect. “I think this was an attempt to get rid of a whole category of people from being able to take tax deductions,” she said. “I’ve done a lot of political work that is not so easy, and it’s not easy to show or to sell. But I’m an artist. And if I’m not considered one, then I don’t know who could be.”
But this is one type of case where I'm glad they've been told to back off. From now on, I hope they refocus on going after people who are cheating in a big way, not artists who just barely are getting by.

Found in an 1884 collection of poems by Henry Wadsworth Longfellow, though the poem was originally published in 1842:
The Quadroon GirlParamour... yeah, right. That's the word for it.
The Slaver in the broad lagoon
Lay moored with idle sail;
He waited for the rising moon,
And for the evening gale.
Under the shore his boat was tied,
And all her listless crew
Watched the gray alligator slide
Into the still bayou.
Odors of orange-flowers, and spice,
Reached them from time to time,
Like airs that breathe from Paradise
Upon a world of crime.
The Planter, under his roof of thatch,
Smoked thoughtfully and slow;
The Slaver's thumb was on the latch,
He seemed in haste to go.
He said, "My ship at anchor rides
In yonder broad lagoon;
I only wait the evening tides,
And the rising of the moon."
Before them, with her face upraised,
In timid attitude,
Like one half curious, half amazed,
A Quadroon maiden stood.
Her eyes were large, and full of light,
Her arms and neck were bare;
No garment she wore save a kirtle bright,
And her own long, raven hair.
And on her lips there played a smile
As holy, meek, and faint,
As lights in some cathedral aisle
The features of a saint.
"The soil is barren, the farm is old,"
The thoughtful planter said;
Then looked upon the Slaver's gold,
And then upon the maid.
His heart within him was at strife
With such accurséd gains:
For he knew whose passions gave her life,
Whose blood ran in her veins.
But the voice of nature was too weak;
He took the glittering gold!
Then pale as death grew the maiden's cheek,
Her hands as icy cold.
The Slaver led her from the door,
He led her by the hand,
To be his slave and paramour
In a strange and distant land!

Well if that's not a title that inspires you to read on, I don't know what is.
But seriously, there's some good stuff here.
Do you wonder where you should be born the next time you're born? The Economist has a nice list of countries, based on 11 indicators. The U.S. ties with Germany at number 16. It's a bit of a weird list (Italy and France are worse than the UAE? Saudi Arabia is better than Mexico or 20+ other countries...did anyone ask the women of Saudi Arabia?).
More evidence that we don't all see the same things as eyewitnesses (or as people watching the same video). In this case, an ambiguous situation with a cop interacting with a citizen. Those whose eyes watch only the cop side with the cop… those whose eyes take in more of the scene and all the players have a more balanced understanding of what took place.
Ending a civil war: has Colombia cracked the code? An editorial from the Boston Globe, recommended by Steven Pinker (akin to positive outcomes in South African and Northern Ireland). Truth and reconciliation, people -- that's what's needed.
Two different Texas men killed cops during no-knock raids on their separate houses on separate dates. In both cases, the homeowners thought their homes were being invaded during the night. In one case, no evidence of any crime was found in the home; in the other, there was a small amount of marijuana. One man is being tried for capital murder of a police officer; the other was not charged because "his home was his castle." One man is white and one is black -- big shock -- and guess which one had the pot and which one is being charged with murder?
Did you know that no one knows how many people in the U.S. are killed by cops every year? Despite all the details our police are required to keep track of (such as how many bullets they fire), they don't have to keep record how many people they kill. Here's yet another example: Louisiana Police Officer Shoots, Kills 14-Year-Old Honor Roll Student.
I just learned about an influential Libertarian thinker named Hans-Hermann Hoppe who makes no bones about saying democracy is incompatible with the Libertarian vision of society. Whoa.
Education "reform": one more way to kill public education. Including this response to those who point out that sometimes per-pupil expenditures are higher in low-achieving schools:
What rich kids have going for them is a hugely larger expenditure per pupil-- just not in direct tax dollars to school district. Buffy and Chip may cost $10K apiece for the taxpayers, but they are also taking tennis lessons and SAT coaching and dance class and a hundred other enrichment opportunities that are not paid taxpayer. Part of being a poor kid is not having your total education subsidized by family and friends.School counselors are important. "Adding just one counselor to a school has an enormous impact on discipline and test scores, according to a new study." To be more specific, "Hiring just one additional school counselor in an average American school could have about a third of the effect of recruiting all the school’s teachers from a pool of candidates in the top 15 percent of their profession." Minnesota -- despite its reputation for quality education -- has one of the worst ratios of counselors to students.
You may remember me mentioning something called the Paradox of Diverse Communities back in May of this year. This was a finding that the "more diverse or integrated a neighborhood is, the less socially cohesive it becomes, while the more homogenous or segregated it is, the more socially cohesive." Which I said at the time was one of the most depressing things I've ever heard, right up there with the finding that when white people are told the criminal justice system is racist, it makes them like it more. Well, here's some good news to balance out all of that negativity: A Sense of Purpose Increases Comfort With Ethnic Diversity.
And here's another one from Pacific Standard magazine: Trust Is Waning, and Inequality May Be to Blame.
Some environmental good news: How solar can become the world’s largest source of electricity by Dave Roberts at Grist.org. And some bad news: Water contaminant (perchlorate) linked to children's low IQs. And some in-between news: Solar power is growing so fast that older energy companies are trying to stop it.
My Daughter’s Homework Is Killing Me. What happens when a father, alarmed by his 13-year-old daughter's nightly workload, tries to do her homework for a week?
Yummmmmm -- bugs! A nice infographic about how insects can feed a hungry planet.
After a Manhattan bicyclist accidentally killed a pedestrian recently, I engaged in a bit of discussion with a friend on Facebook about it. A normally reasonable and progressive woman, she took the hard line that bicyclists are careless, based on the fact that she and her young-teen daughter were once buzzed by a cyclist when they had the right-of-way in a crosswalk. I pointed out that cars kill and endanger pedestrians all the time, but few people seriously say cars (or actually, their drivers) should be more restricted, and that the killer biker was a man-bites-dog situation. She stuck to her condemnation of cyclists in general. Later, I found this article by a New York cyclist that did a nice job of dealing with the nuances of the specific incident. The writer ends with this:
It is, after all, the central tragedy of traffic in New York City and many other big cities that so many people walking and cycling – using the least harmful transport modes – end up in cold mortuaries and warm intensive care units. It’s a horror that’s no less intense for being widely taken for granted. I will do everything I reasonably can to ensure I’m not responsible for putting anybody else in those places.Why 12-foot traffic lanes are disastrous for safety and should be replaced now. From the Atlantic's CityLab. Lane widths in my city of Saint Paul are standardized on 11 feet -- not as bad as 12, but still too large.
That's it for the tabs right now. Whew.
