Tiffany Jenks Update: Joshua Robinett Again Arrested

On a different section of this site, I’ve talked at length about the murder of my former flatmate, Tiffany Jenks.

One of the trio of people involved in her death, Joshua Robinett, was arrested on charges unrelated to Tiffany on November 11, in Multnomah County. He now faces new charges of Assault, Harassment. (At least, I presume it’s the same Joshua Robinett; the mug shot looks like him, and the age matches.)

Note: a prior version of this post, included Attempted Rape among the charges. That has been dropped, leaving only misdemeanor assault and harassment in what, from the few documents presently available, appears to have been a domestic violence situation. (Thanks to a friend who’s good at searching court records for puzzling this out.)

Uncovering COVID-19’s Most Risky Activities

I don’t have time to digest this in detail today, but this is important. It’s condensed from a press release from Nature (slightly edited to condense it):

“Reopening places such as restaurants, fitness centers, cafes, and hotels carries the highest risk for transmitting SARS-CoV-2, according to a modelling study based on data from the United States published in Nature. Reducing occupancy in these venues may result in a large reduction in predicted infections, the model suggests.

“Jure Leskovec and colleagues use[d] US mobile phone data (collected between 1 March and 2 May 2020) to map the movements of millions of people from different local neighbourhoods. They combine[d] these data with a model of SARS-CoV-2 transmission, which allow[ed] them to identify potential high-risk venues and at-risk populations.

“The level of detail of the mobility data allowed the researchers to model the number of infections occurring, by the hour, at nearly 553,000 distinct locations grouped into 20 categories — termed ‘points of interest’ — that people tended to visit regularly. Their model predicts that a small number of these locations, such as full-service restaurants, account for a large majority of infections. For example, in the Chicago metropolitan area, 10% of the points of interest accounted for 85% of the predicted infections at points of interest.”

That’s a bit technical, but it says what we all need to realize: certain activities are higher risk, and high-risk activities account for the vast majority of the virus’s spread.

Today, this also would, most likely, include Thanksgiving festivities.

We have a vaccine on the cusp of becoming available. Patience will save lives. Be patient. Hold the course. The end may be in sight.

One caveat re the study: it’s data are from the first wave of the pandemic, in March and April. Some of the “points of interest” may subsequently have learned how to reduce the risk. But the main idea still applies: the vast majority of the spread comes from a small fraction of sources.

This finding is particularly interesting: “[C]apping the occupancy of a venue at 20% of its maximum capacity is predicted to reduce new infections by over 80%, but would only reduce the overall number of visits by 42%.”

Calculating the risk of Thanksgiving dinner

Want to know the risk of being exposed to COVID-19 at your Thanksgiving dinner? In a paper released today by Nature Human Behaviour (part of the Nature family of prestigious journals), a team from Georgia Tech has created a handy-dandy online calculator that can do just that—as well as calculating the risk of being exposed at any other social gathering of any size, anywhere in the U.S. (and in some other countries).

Cutting edge science it is not: the math is basic probability. But it’s a cool website to play around with, and the announcement is very, very timely.

It’s primarily oriented toward policy-makers trying to decide what types of gatherings to allow, but it’s also revealing to any of us who are simply curious…and concerned about stemming the rapid spread of the virus.

Simply use the slider to pick the size of your event, then hover the cursor over your county, and it will tell you, based on current infection rates, the probability that at least one person is infected. (Note: it does not work on all browsers. Here’s the direct link in case you need to copy it to another browser. For me, it works on Firefox, but not Safari. https://covid19risk.biosci.gatech.edu/).

For example, it tells me that in Portland, Oregon, a gathering of 50 people has a 38 percent risk of having one or more infected people present. Ouch. Having ten people over for Thanksgiving isn’t as risky, but still carries a 9 percent chance.

And it’s a lot worse elsewhere. In my brother’s county in Iowa, a 50-person church service carries a stunning 97 percent chance of drawing an infected person, and that not-all-that big Thanksgiving dinner has a 50 percent chance.

There are some caveats.

  • The figures are based on the presumption that cases are under-reported by a factor of 10, something that is backed up by antibody tests in some parts of the country, but not others.
  • It assumes that everyone who tests positive is infectious. I don’t know if that’s true.
  • It does not tell you the chance that you yourself will become infected.

But if you’re looking for a reason to wear a mask, avoid large (or even mid-sized) indoor gatherings (and crowded outdoor ones), and to postpone major holiday celebrations, this is it. Me, I’ll celebrate Thanksgiving on my own, looking forward to next year, hoping to maximize the chances that my friends (and their loved ones) will still be alive to do it.

50 Years Ago on a Beach in Oregon…

Today’s big news was the apparent success of the Pfizer COVID-19 vaccine. That was fun and exciting. But, this week is also the 50th anniversary of Oregon’s most famous news story.

What’s that, you say? The passage of the nation’s first bottle bill? The beach bill? Any of the other things that put Oregon on the map in the 1970s?

Nope. And beware, this one might cause you to you laugh hard enough to make you blubber.

It’s the story of a good idea that went a bit off the rails. Enjoy.

BTW, the newscaster is still on the air.


The Race I Never Dreamed I’d Run

Ten years ago, I had knee surgery.

I will never forget what the doctor told me when I woke up. “It’s worse than we thought.” He then added that the drugs from the surgery would mean that I wouldn’t remember those words, but he was wrong. Running as I knew it ended that day.

Seven years later, I had a hip replacement. Arthritis is the family bane. But this time, I wasn’t even thinking about running. Not only had I gained dozens of pounds, but the hip was so bad that the surgeon took one look at the X-ray and said, “That’s a bad hip. Let me check my schedule to see if we can move up your surgery.”

She did, for which I was grateful. I’d reached the point where the 150 meters from the nearest parking spot to the track where I was then coaching had become the longest walk I could manage without a break, and I took it for granted that there would be a time or two each day when the pain would be enough to make me nauseous.

But this is not that kind of story.

Because earlier this month, I rediscovered racing.

Masks: the Golden Rule is not a sign of weakness.

I’ve said this before (in fact, I’m using the same photo as last time), but it’s worth repeating. The latest run of the University of Washington’s coronavirus model shows 363,000 deaths by the end of December, with the death rate hitting 2,900 a day by then–a horrible projection for what might happen in January.

But if we can raise the rate of mask-wearing, especially indoors, that number of deaths falls by 86,000. Given that more than 200,000 people have already died, that means the number of new deaths is cut in half. Simply by biting the bullet and wearing masks. (Note, I may not have these figures exactly correct; this was breaking news on TV a few minutes ago, and I didn’t have time to grab a pen. But I’m close enough.)

Mask wearing is not a sign of weakness. It’s not even something you do for yourself. It protects you some, but it works best if the people around you are also doing it.

Mask wearing is something you do primarily for others.

If they reciprocate, THAT protects you. But even if they don’t, it sends a signal of strength. “I care.” Why is that so controversial?

It’s the Golden Rule in action.

It’s that simple.

My 2016 Book…and the London Marathon

Back in 2016, I coauthored a short book (more a novella than a novel) with Phil Maffetone about a hypothetical “Million Dollar Marathon,” in which runners competed on a one-mile track, with the giant prize to anyone who could break 2 hours.

It’s fiction—I thought of it as near-future science fiction, since that is part of what I write—focused on a Tibetan refugee whose background gives him all the tools needed to make this quest possible.

Now, this weekend, the London Marathon—thanks to COVID-19—will be conducted under a protocol amazingly similar to that in our book. The best in the world, male and female will duel on ~20 laps of a 1.34-mile loop.  Not a track, but not all that different from Phil’s and my setup.

COVID-19 Becoming More Infectious, Study Says

Buried in today’s political news was a new COVID-19 study from Texas that found that the virus is becoming more contagious, and possibly increasingly able to circumvent control measures such as masks, hand-washing, and social distancing.

It’s really depressing news, though not really unexpected. What the researchers found was that 99.9 percent of recent cases in Houston appear to come from a previously uncommon strain of the virus—one that produces greater numbers of virus particles in their noses, mouths, and lungs.  That means that when they breath, talk, shout, cough or sneeze, they expel more virus particles, increasing the chance that someone nearby will receive an infectious dose.

The paper is posted on MedRxiv, an online site where scientists can post preliminary results while awaiting official publication. And while that means it isn’t peer reviewed, this doesn’t appear to be the type of research that can be easily messed up—especially if we don’t really care whether it’s 99.9 percent of new cases or 99 percent, or even 90 percent.

Quick high-veggie hot dish

With all the political news raging this week, I figured it was time to do something different. Here’s a quick recipe of my mother’s, adapted to my tastes. It makes a very good potluck dish (it always gets raves), a side dish for dinner, or a great lunch. (I used it on my diet.)

Basic ingredients:

  • 1 can corn (or fresh corn, but that takes longer)
  • mushrooms (1 small can or fresh; fresh is better)
  • half a large onion
  • 1 ounce mozzarella cheese
  • Small sweet peppers (red, yellow, orange)
  • Jalapeño
  • Roasted cashews
  • Salt (if desired)
  • Pepper
  • Garlic powder (minimal)
  • Parsley flakes
  • Paprika
  • Cumin

Drain canned veggies and put them plus chopped fresh veggies in a microwave-safe casserole dish. Add spices to taste. Place sliced cheese and cashews on top. Heat on high until cheese melts and everything else is sufficiently hot. (If preferred, you can give the chopped onion a head start, but I generally find that unnecessary.)

Serves 4 as side dish; or one as lunch. (Total calories about 450, depending on how many cashews you use.) For heartier version, use more cheese.

When 6 Feet Apart Is and Isn’t Enough

One of the standard pieces of advice for people trying to prevent the spread of COVID-19 is that we need to either stay 6 feet apart or wear masks. But does anyone really believe the danger zone is that sharply defined? Especially because study after study has shown that exhaled droplets, especially small, can travel larger distances than once thought.

At the same time, we know that ventilation matters, because it markedly affects the number of virus particles you might inhale if you are unfortunate enough to be exposed.

A new paper in BMJ (formerly the British Medical Journal) has addressed that topic in unusual detail, producing a very thorough (and easily read) graphic detailing the relative risk in a wide range of situations.

The result is good news for outdoor enthusiasts (such as runners, cyclists, and hikers), mixed news for outdoor gatherings, and bad news for bars and restaurants.

Nothing surprising there, but the graphic is cool, and useful.
