Well, GPR works based on reflecting em waves, so it runs into the same issues that pure electric geophysical methods and purely mechanical geophysical methods run into. Mechanical challenges like scattering or interference from voids, thin nonrepresentarive layers, layer inversions, boulders, etc. Electrical challenges like water content variations, voids, salt/contamination, etc. They are also generally way lower resolution than the layman would expect.
Electrical methods are generally more sensitive to moisture content, and in my experience, are more likely to detect a change in moisture rather than material (material and moisture are generally correlated). And that's kind of the thing with most geophysical methods, they're telling you when a material changes and by moving your sensing equipment you can see how that change is related to space.
There are GPR "suitability maps" for the US that show vaguely where you can expect GPR to be accurate. I haven't seen one for Canada though, but GPR would be usable in areas with similar surface geology.

As someone with fairly extensive geophysics experience, GPR is pretty meh and I've always found it weird that it's treated as though it was anything other than a very noisy form of sensing that can only tell you when the subsurface material changes (and even then, the depth and size of the change is hard to ever be sure about). Geophysics is inherently very unreliable when it comes to trying to identify small changes below the surface and I'm very much not surprised that these graves are false positives. Plenty of the actual papers that back up the use of the GPR for this purpose found as much and similar uses, like detecting utilities or animal burrows or cavities is just as unreliable. The effectiveness of GPR also depends on the materials involved, which can reduce your penetration to mere inches.

I mean, I'm speaking to my experience in Austin, where you go half a mile from downtown and any undeveloped wood will have a massive 10-20 person camp complete with literally tons of trash and thousands of used needles. This is a hazard that comes up in many new construction projects. For commercial work, it gets dozered into a dumpster or buried on site. For state work, it usually turns into a huge health and environmental hazard requiring more consultants and specialists to document and remove these materials (the new TxDOT campus was delayed for almost a year over this issue).
So in my experience, these kinds of camps are some of the worst for drug abuse and theft just generally the most negative kinds of homeless. But it's also a good point that plenty of semi-functional people don't his as well. Hell, I considered doing this in college to save on rent.

One of the major problems win any homelessness related study or homeless census is that they only interact with the homeless in shelters and the most agreeable ones on the street. The ones in super-camps in the woods or parks are beyond the resources of most organizations and cities to locate, let alone survey. Additionally, the homeless are obviously highly mobile and move around a city throughout the day, so visiting a particular freeway overpass camp won't capture data about any one in a food tent, public library or a block over panhandling. I don't see why this particular paper is supposed to have solved these sampling issues.
For whatever reason, Desantis has been utterly unwilling to criticize Trump
Well, he has definitely avoided total war with Trump, but he has criticized Trump on several issues including abortion, covid policy, his handling of the capitol riots, and (obliquely) attacking him as not critical enough on gender issues. So I'm not disagreeing with you on principal, merely on the degree.
I suppose that could be part of the problem though. They seem to be avoiding directly attacking Trump, presumably to avoid alienating MAGA folk, but that in itself doesn't signal to those people that you are any better than Trump on the issues they care about. Sort of a reverse version of the "extreme in the primary, moderate in the general" formula aspirant presidents stick with. This is looking like a good example of why that formula is so prevalent.

That's part of what I find perplexing about it. If the neocon/establishment part of the party had been paying attention to DeSantis since he won his governorship, I do not think they would be so quick to back him. I think "anyone but Trump" has clouded their judgment, and perhaps you're right that being endorsed by that part of the party is clouding the judgement of the "anyone but neocons"/populist part of the party.

This touches on why I'd rather not vote for Trump, but will if it comes down to it. I don't know why anyone expects Trump to put together a more competent staff than the first time (where his people seemed notoriously ineffective and disloyal). That's not to mention the backstabbing and constant undermining from his own party leadership.
From a culture war POV, I would gleefully root for someone punishing DNC bad actors and the embedded bureaucracy, but I don't see anything that makes me think Trump would be capable of doing so. That said, if Trump were to win, it would at the very least signal something to my outgroup, and short of an actual decisive victory, that may have to suffice.
It's interesting to me that DeSantis (my preference) pitched himself as a competent and respectable Trump-like figure, and yet that hasn't won him much ground so far. I would think that would unify right wing voters, but apparently not.

I vary based on season. Living in the American south, the temps strongly affect whether a scent is overbearing or weird in my opinion.
Winter - Burberry London
Spring - Guerlain Jicky
Summer - Guerlain Vetiver or Burberry Brit
Fall - Guerlain Habit Rouge

Suppose you are managing a very basic, but busy archive that adds dozens if not hundreds of new documents per day.
How many school libraries could this possibly describe? I think you and many others are conflating school libraries with public libraries. The latter are relatively large and provide all manner of community services and I could imagine a 2 year degree program could be necessary for managing such a thing. The former are small and often staffed by community volunteers or teaching assistants. I am not convinced that grad school or even a bachelor's is necessary for this function.
Without a computer
How many libraries of either variety do you think there are in US that don't any kind of computer or digital inventory management? Regardless, you could probably learn such an organization system in your bog standard 30 hour technical training class.

Idk do you really need librarians as such in 2023? What exactly do they do that some lower level admin without a corresponding graduate degree would be able to do?
Is there much evidence that the presence or lack of presence of a librarian or library has much of an effect on student outcomes?

Perhaps but then you run into the same failure mode ad Google+, which was a functionally great social media platform with a lot of good ideas and was very hot when it first launched. The invite only character made it exclusive and exciting...for a few months when everyone realized that the appeal of social media is having that un-gated garden of millions of other people to potentially interact with. Interest and use dried up as suddenly as it came and the rest is history.
I have nothing charitable to contribute to most of this. I find 99% of the speculation about this conflict to be in bad faith and based on very little in the way of facts (which as faceh points out, we don't have and can't separate from non-facts reliably or quickly). I find myself intensely frustrated with the expert class and their endless essays and videos that at this point seem clearly to be little more than self aggrandizement and wish casting.
That out off my chest, I would like to point out that over the last couple of months Prigo had made a few videos that seemed increasingly unhinged and paranoid. He was complaining about the contract negotiations with the MoD falling through and them straight up refusing to communicate with him about it and he was convinced the MoD was going to assimilate and take Wagner from him when the contract ended (I believe in July). With the current rumors of Prigo's deal with Putin and Lukashenko consisting of cash, voluntary exile for Prigo and his men who mutineyed, and assimilation of the rest of Ukraine-front Wagner into the MoD, I think it is quite likely that this entire event was the result of a banal contractual dispute mated with (justified) paranoia and personal enmity with the military bureaucracy. Yes, yes, I know, it's a lot more boring than it being some 4D chess by Putin or [long philosophical argument on the inherent inability of those subhuman Russians to self govern because of reasons].
As you point out there are still some very big questions left here. There were videos at the time of Rostov's occupiers denying that they were Wganer. There is the effectively painless penetration of Russia almost to Moscow in just hours despite this being exactly the kind of thing Russia has been worried about, preparing for, and strategizing over since the czars. I don't know what to speculate other than that I do not think it was 4D chess, but once Wagner mobilized, it may have been used that way for a variety of reasons (did Putin's very close relationship with Prigo keep the MoD from raining hellfire on them until a settlement could be worked out?) Will there ultimately be a shake up with the MoD in the next months? Will Belarussian Wagner open up a new line of attack into Ukraine? Where were the Rosgvardiya, who report directly to Putin in my understanding, in all of this and why is the death toll almost non existent?

Ticks will stay on your body for comparatively a much longer duration than mosquitoes. I don't see how there's any actual benefit from a mosquito having any kind of analgesic property when they'll finish sucking and fly off in seconds. The benefit to a tick is much more obvious.
Additionly, as someone in the American south and no stranger to "skeeters" and ticks, I don't know that I've ever had a mosquitoes bite become itchy as quickly as you describe.

Mosquito bites transmit bacteria and such as well as mosquito saliva which triggers an intense and localized inflammation response. Same thing with ticks and other blood suckers.
These are substances that require some amount of time for the body to notice and react, which is why bites don't hurt immediately or even shortly after receiving them. The mosquito has already fed and gone by the time the bite starts swelling and itching.
I did lot in my grad school research, mostly seismic and resistivity. A little professionally afterwards.
Most won't have the resolution to pick up a small, residential burn pit, depending how deep it is anyway. Electrical methods might pick it up, since they're sometimes decent resolution near the surface.
In foundation engineering, finding trash pits and burn pits during development when doing test borings or excavations in long developed areas is pretty common. God forbid you hit an undocumented landfill. That's a good way to get your project delayed ($$$). Sometimes you'll need to have a cultural study done if they think it could be a historical landmark or archeological site, so your idle thoughts aren't too out of line with reality ha.
