A college student expresses some stark realities

Excerpts from an eye-opening essay by an undergraduate student:
I was surprised to find I spend far, far less time on my classes than on my extracurricular activities... It turns out that I’m not alone in my meager coursework. Although the average college student spent around 25 hours a week studying in 1960, the average was closer to 15 hours in 2015...

This fall, one of my friends did not attend a single lecture or class section until more than a month into the semester. Another spent 40 to 80 hours a week on her preprofessional club, leaving barely any time for school. A third launched a startup while enrolled, leaving studying by the wayside... These extreme examples are outliers. But still, for many students, instead of being the core part of college, class is simply another item on their to-do list, no different from their consulting club presentation or their student newspaper article...

Half of the blame can be assigned to grade inflation, which has fundamentally changed students’ incentives during the past several decades. Rising grades permit mediocre work to be scored highly, and students have reacted by scaling back academic effort...

And therein lies the second reinforcing effect of grade inflation, which not only fails to punish substandard schoolwork but actively incentivizes it, as students often rely on extracurriculars to get ahead. Amanda Claybaugh, dean of undergraduate education, made this point in a recent New York Times interview, saying that “Students feel the need to distinguish themselves outside the classroom because they are essentially indistinguishable inside the classroom.”..

One of my classmates last semester, who is one of the more academically oriented people I know, told me that to get the best grade on an important essay, he simply “regurgitated the readings” without thinking critically about the material...

This utilitarian approach to schoolwork requires a cultural explanation beyond grade inflation, and some of the blame must be placed on the newly meritocratic nature of college admissions. Although the partial shift away from the monied legacy networks that dominated Ivy League spots has been beneficial overall, the change also initiated a résumé arms race... nationwide surveys of incoming freshman confirm this narrative, as an increasingly large share of first-years view college as preparation for financial success rather than a site of learning per se...

This attitude is one manifestation of what Fischman and Gardner call a “transactional model” of college. According to their book, a so-called transactional student “goes to college and does what (and only what) is required to get a degree and then secure placement in graduate school and/or a job; college is viewed principally, perhaps entirely, as a springboard for future-oriented ambitions.”..

In contrast, a professor who is also a College alumnus recently told me that he spent most of his time at Harvard taking five or six classes a semester without doing extracurriculars. Hearing that made me think I’ve probably approached this place in the wrong way. I was discussing the professor’s comments with my roommate the other day, and we both agreed that if we were to go back and redo our undergraduate education, we would basically drop all our extraneous clubs and take as many classes as possible.
I'm sure this essay will trigger a lot of responses from readers (most of whom have probably attended college and experienced similar (or opposite) situations, and I anticipate some vigorous comments.  I would encourage you to read the essay in its entirety and not rely on my focused excerpts.  And note the student is at an elite university, but the principles expressed likely extend broadly across the academic world.

Jon Stewart on "victimless" financial crimes


This Daily Show monologue started with commentary about Donald Trump, but in the embedded segment he extends the argument to the wider financial community:
"He's commiting bank fraud where there is no victim"
"No victim.  The ruling is blatantly unfair."
"That didn't go over well with the investment community, because we're asking each other "who's next"?"
"Every [crime] you've just listed is done by every real estate developer..."
According to Stewart the system is "incentivized for corruption", and that apparently if enough people commit a crime, it automatically becomes legal.

Try to watch the video without getting mad at the US financial system.

I'll file this post under "humor" but it's really trenchant social commentary.

What's wrong with people these days??? Updated.


I have fond memories of walking along Hadrian's Wall when I was a younger man.  This wasn't a whimsical folly; it was planned vandalism requiring heavy power tools or a two-man crosscut saw.  Whoever did this should be castrated.  Publicly, IMHO.

The embedded image is a composite I made of screencaps from a video of the incident.  In the video a park ranger explains that it is impossible for staff top monitor the entire recreation area, and asks the public's help in this regard.

If your rotissserie chicken is green on the inside...


Image from the Costco subreddit, where the top comment is that this is "green muscle disease."
"There is no evidence that Green muscle disease is caused by a pathogen, so technically it would be considered safe to consume a bird with it. However, it may not be aesthetically pleasing to eat green meat. The green discoloration of the meat is similar to a bruise that is trying to heal."
Additional information from an AOL webpage:
Green muscle disease — which is also called ischemic myopathy, deep pectoral myopathy, or green breast — is a condition that develops in larger chickens or turkeys when their pectoral muscles are overdeveloped, becoming too large for the blood supply to reach that region. According to the U.S. Department of Agriculture (USDA), when birds use those muscles to repeatedly flap their wings, the exertion causes the muscles to swell, further restricting the blood supply to that area. Without adequate circulation, those muscles die, turning green in the process.

The comparison to a bruise evolving from reddish-blue to green is accurate.  The green color arises from the breakdown of hemoglobin or myoglobin in the dead muscle.  This is way different from the green color in wounds that arises from the presence of bacteria like Pseudomonas aeruginosa, whose presence should be detectable by a foul and nauseating odor.*  So in the case presented, there would be no disease risk in eating the normal parts of that chicken.

This report was sent to me by a pathologist, who commented that "green muscle disease" should be called what it is: necrosis.  I'll add a comment to express my dismay about the extent to which our food service industry is now bioengineering fowl.  I knew that turkeys were falling over from overdeveloped breasts, but this is the first time I've heard about vascular insufficiency in the poor creatures.

*historical anecdote re Pseudomonas.  When I was working the major medicine ER in Parkland Hospital decades ago, a patient was wheeled into a closed examining room suffering from a decubitus ulcer that extended from his shoulders to his coccyx, the entire extent glowing almost neon green from Pseudomonas colonization.  A series of nurses went into the room to examine him and prepare him for admission upstairs, and at least two of them exited the room wretching or vomiting.  I have always had the deepest possible respect for Parkland ER nurses, who are tough as nails and have seen everything there is to see.  The reason these two were retching has nothing to do with squeamishness; the detection of the odor bypasses the cortical analytic processes and goes directly to the brainstem to produce nausea - a vestigial reflex that natural selection employed to protect our earliest ancestors from dangerously contaminated meat.

Interesting album page from a stamp collection


Screencap from a lot I saw posted on eBay.   Stamp collectors should lean back so as not to drool on their keyboard.

Before you complain about the postal service...


... study this table.  Details from NPR:
The office compared the U.S. to 30 other nations that were selected by country size and postal service revenue, as well as the ability to source reliable data. The list includes much of the European Union, along with countries such as Canada, Japan, Brazil and Russia.

In raw numbers, only four countries had cheaper stamps than the U.S. And while many postal services have raised prices in recent years, the U.S. increases were moderate compared to most nations in the sample.

"The price of a [USPS] stamp increased by 26 percent from June 2018 to June 2023 ($0.50 to $0.63)," the inspector general report states, "which is less than half of the average increase for our sample size (55 percent) during that period."

When the OIG adjusted its analysis for purchasing power parity — a currency conversion rate used to compare the relative affordability of goods in different countries — the U.S. had the lowest stamp price of the 31 postal services.

Finding "dark skies" - updated


Those who wish to see the skies as their grandparents did and appreciate the magnificience of the Milky Way would do best to find a "dark sky" away from the contamination of urban lighting.  I made the screencap above from a world map at DarkSiteFinder.

It's zoomable to tell you which way to drive from Salt Lake or Park City for stargazing -

?why the hot spot in subSiberian Russia?  Perhaps burning natural gas from oil fields?

Found via an article at FiveThirtyEight about The Darkest Town in America, which discusses the environmental and health effects of nocturnal light pollution.

Goodbye to one of my favorite comics


Real Life Adventures ended on September 23.  
No word on why the cartoonists are retiring, although the strip has been going for 32 years, and writer Lance Aldrich has turned 78, and there are only four newspapers left in the United States that even run comics, so it’s easy to make up a plausible story.
I have harvested their material frequently (here, here, here, here, and many more) for the humor subsection of TYWKIWDBI, and will truly miss their panels.

A memorial to the World Central Kitchen heroes


Tributes to each of these workers have been posted, with details about their histories and personalities.

The fact that these people were specifically targeted, and were targeted because they were humanitarian aid workers is particularly appalling, and deserves not only censure but also prosecution as a war crime.  More on this later.

The significance of airport runway numbers


TIL from the NYT crossword that airport runway numbers have directional significance, as explained in Wikipedia:
Runways are named by a number between 01 and 36, which is generally the magnetic azimuth of the runway's heading in decadegrees. This heading differs from true north by the local magnetic declination. A runway numbered 09 points east (90°), runway 18 is south (180°), runway 27 points west (270°) and runway 36 points to the north (360° rather than 0°)... A runway can normally be used in both directions, and is named for each direction separately: e.g., "runway 15" in one direction is "runway 33" when used in the other. The two numbers differ by 18 (= 180°).

A haircut and a crocheted rat


Both images from the ATBGE (Awful Taste But Great Execution) subreddit, which is an interesting (and well-named) website to explore: hair (cropped) and rat, if you want to browse the comments.  I can't think of anything to add.
