Of the twenty richest cities in the world, eleven are in the US.

    No, there are only two barriers to the adoption of 5G in the US: (1) A political culture reluctant to adopt and promote technical standards and (2) the fact there is no such thing as 5G.

    Clearly we have the technological capability to create self-driving cars that are safer than the vast majority of drivers on the road. But for whatever reasons -- retail cost or risk management -- manufacturers aren't quite ready to jump in all the way. Introducing self-driving functions piecemeal is bound to create a transition period in which users misuse those functions.

    The implicit dichotomy you're asking us to assume is bogus: i.e., that activism can't be based on scientific knowledge. We can't answer the question the way you'd like it to be with out accepting a counter-factual proposition.

    Clearly this is activism at any rate. That doesn't make it untrue or unsupported, although obviously one could look critically at the presentation of the data and find flaws in the statistics and methods used.

    Now common sense should tell you that we're almost certainly using resources at a higher rate than ever before, simply because the world's population is greater than it has ever been before, and Gross World Product is greater than it has ever been before -- although admittedly some of that is intangible stuff like intellectual property. But it's a safe assumption that we are consuming physical resources at an unprecedented rate.

    The most credible line of attack for a figure like this is that it must in some way combine apples and oranges from a dynamic standpoint. For example, suppose you remove a ton of fish from the sea, does that move you a ton closer to depleting fish stocks? You can't say, because it depends on whether fish populations are at, near, or far from equilibrium. Removing fish from a population at equilibrium causes the system to produce exactly enough to produce exactly enough more fish to replace them; hauling the last mommy and daddy fish from the sea destroys that population forever.

    So you're on most solid ground when you talk about specific resources. But some kind of composite figure does make sense if you want to think about human impact as a whole, as long as you don't ask too much of such a figure.

  12. I know the Keys Mosquito Control District well. on Florida District Considers Releasing GMO Mosquitos After Cayman Islands Experiment (accuweather.com) · · Score: 2

    They were one of my clients for many years, until I sold my company about ten years ago. They are almost certainly the most sophisticated and technically capable mosquito control operation in the world, and I've worked with hundreds of them.

    Many visitors to the Keys are unaware of the potential for a hellish mosquito problem there. This is not a natural situation. There are few places that have such a concentration of prime mosquito habitat next to dense human populations. If the Florida Keys Mosquito District simply stopped doing mosquito stopped doing mosquito control, I am confident that within a year the problem would be so bad that keys would be largely depopulated. Tourists, even many residents remain blissfully unaware of this because FKMCD is also one of the most effective district anywhere.

    One of the reasons the FKMCD is so effective is it has been willing to try things that nobody else has ever done. For example they did a study of how well common pesticides actually work on the mosquitoes in their district. You'd think every district would do this routinely; after all it's pointless to spend money on pesticides your mosquitoes are resistant to, but nobody does it but FKMCD. The way most agencies choose pesticides is they go with the cheapest one. And if that doesn't work, they use more of it. FKMCD *knows* what works in their district, and how much they need to use. When you spend a million and a half bucks a year on pesticides, this is a big deal: in saving money, in reducing environmental impacts, and in keeping people from getting bit.

    FKMCD has put a huge amount of investment into rapid response. Usually when a district goes out to spray an area it's in response to information that they received days, or even weeks earlier. This is not cost effective because usually the problem will have run its course by then; the mosquitoes just aren't there, they're somewhere else. In the Keys if you see a spray truck you can be sure it is being directed from data that is about twelve hours old. Since fogging has to be done in the wee hours of the morning, this is the theoretical limit for how quickly you can respond to information you receive during the day. Faster and more targeted response was the major focus of my work with them, and they paid me a lot of money to achieve success at that. It was money well spent, if I do say so myself.

    This cost-is-no-object approach enabled FKMCD to achieve things that other districts can only dream of. On the other hand, it has its downsides. You could argue that the agency doesn't have to be quite as vigilant as it is, and that its success was fostering a cavalier attitude about ratepayer money. A few years ago the second-in-command was caught giving a company phone to his wife and daughter, something which did immense reputational harm to the district.

    Also across Florida in the 2010s there was a movement by Tea Party to gain control of local government boards. The "Mosquitoeers" campaigned against sitting mosquito control board members by linking them with Obama, and this proved successful, even in the Keys. The results, according to the people I stay in contact with, is that spray missions have had to be curtailed because of vehicles with worn tires, or even running low on pesticides -- something that was unheard of ten years ago. They've also had management turnover -- their long-term and very experienced director retired and the replacement left after a few short years.

    Still, if there's any district that can do this pilot project and track the effectiveness of the results, it's FKMCD. It is the ideal place to try it. And you just can't go off half-cocked in the Keys either, because Federal regulators watch the place like a hawk. Hopefully this represents a turn to a more balanced approach -- still aggressive and innovative, but a little more cost conscious.

  13. It's just the wrong kind of ship. on Luxury Liner SS United States Cannot Be Put Back In Service (miamiherald.com) · · Score: 3, Informative

    $700 million is comparable to what you'd pay to construct a brand new cruise ship. And what they'd end up if they renovated the United States wouldn't be a cruise ship, it'd be an ocean liner.

    The difference between a liner and a cruise ship is this: a liner is built to perform regularly scheduled service between ports. Even if the seas are high and there's a storm blowing an ocean liner still goes out because her purpose is to get her passengers to point B when the schedule says they'll be there. So an ocean-liner has to be built to be very fast and very seaworthy.

    When air travel supplanted sea travel the companies who owned ocean liners repurposed them for leisurely pleasure cruising. However for this purpose ocean liners are over-built in certain respects and under-built in others. A cruise ship doesn't have to be fast, or shed high seas or stand up to gale force winds. What she needs to do is to take as many people and amusements as possible, at a leisurely pace, into as many interesting places as possible.So cruise ships look nothing like the elegant ocean greyhounds of old like the SS Normandie or the SS United States. A modern cruise ship is basically a top-heavy motorized barge which, despite having jaw-dropping dimensions, can squeeze into shallow harbors that normally can't handle big ships. And they're pokey, even by the standards of 1930s ocean-liners. Cruise passengers aren't really paying to go places, they're paying to spend time on the ship. The ship's ports of call are just for breaking the monotony of incessant luxuriating.

    At present there is only one active vessel in the world that is capable of providing true liner service: the RMS Queen Mary 2. Although she resembles a modern cruise ship in her amenities she carries relatively few passengers (2700) for her size (79,000 tons) and cost ($900 million). For a hundred million less you could have a pure cruise ship that carries 1/3 more passengers, and into shallower harbors too. She couldn't sail around the Horn in July in the teeth of a winter gale, but the market for that particular experience is somewhat limited.

    Looking at the article, one of the concerns that led to abandoning the SS United States project is the stability of the ship. So clearly they weren't restoring the United States to her original 1950s configuration. That was stable enough but only provided 1900 berths, and those in conditions that while elegant enough would be spartan by modern standards. You wouldn't have swimming pools, bowling alleys, planetariums, or any of the other ridiculous things modern ship designers throw in to astonish and delight their customers. These people must have wanted to transform the SS US into a kind of hybrid liner-cruise ship like the QM2. For that they'd have add space for a lot more passengers along with all the amenities they'd expect on their very expensive vacation. Since you can't make the hull bigger, that means building up. Way up.

    Even if they succeeded in the technical challenges of squeezing all that stuff into the hull, the commercial viability of the project is doubtful. There is no practical need in this world for a vessel like the QM2; her sole reason for existing is thrilling customers who are so jaded that an ordinary extraordinary ship just won't do. Only an unique ship will.

    Actually, some of the key papers behind the "replication crisis" notion haven't stood up to scrutiny. I am not being ironic here; the non-replicability results haven't been replicated.

    This of course is normal for science. Error is an expected part of the scientific method; the existence of non replicable results is presumed. That's why when a hypothesis is proposed it's almost always immediately refuted. Then it will be un-refuted, and after that re-refuted. This continues until evidence begins to decisively mount on one side or the other. So there may be a replication crisis; there may not be. As usual we won't know until the tennis match is over. This by the way is why layman shouldn't ever use individual scientific papers in making any kind of important decision (e.g.,what is healthy to eat). You should only rely upon either a trusted expert, or review papers published in high-impact journals.

    The only way funders can increase the speed of purging bad results is to increase funding. There's no way they can ensure that the results they pay for will definitely be reproducible without putting their thumbs on the scale in favor of or against. That of course would get you the appearance of the result you want without the substance.

    As for the number of useless papers, everyone knows this is true. The reason nobody has done anything about it is that the forces creating this problem are decentralized; nobody has control over them. On one hand you have thousands of tenure committees exerting publication pressure on untenured faculty. On the other hand you have thousands journal editors eager to pad out their publications even if it means accepting duff. This doesn't seem to be an issue that funders can fix. I don't know if anyone has studying the economic costs of pot-boiler papers, but from what I've seen crap papers are generally not high rent affairs. People for the most part don't seem to take major grants and produce pointless papers; they cobble together their pot-boilers out odds and ends they have lying around.

That brought wealth and knowledge into Italy, making the Renaissance possible. So no Ghana, no European civilization as we know it.

    I spent about fifteen years of my career in the non-profit sector, so I have some perspective on this.

    Raising money in a non-profit is just like selling stuff is for a for-profit. Generating gross revenue is relatively easy -- if you spend a lot of money you can rake in a lot of dough. What's a bitch to generate is net profit. In the non-profit sector we don't use the term "profitability" very much, so the metric that's often used to describe financial is "cost to raise a dollar." For typical fundraising activities cost-to-raise-a-dollar runs from 0.25 to 1.5 dollars/dollar.

    Take junk mail. The cost to raise a dollar for a well-run direct mail campaign is in the range of $1.25 to $1.50, so if I want to raise $115,000 to spend on other things I have to scale my direct mail campaign to bring inover $258,000 gross. As you can see I chose a net target that was exactly 1/1000 the size of the ALS bucket challenge net, so you can compare the efficiency of the processes readily. The cost to raise a dollar for the ALS bucket challenge is actually better than a well-run direct mail campaign -- $0.91.

    And it should be more efficient than direct mail, because direct mail is about the least efficient method there is. The marginal costs are huge because you pay for the names and addresses as well as printing and mailing of each piece, and most of those pieces will end up in the landfill unopened. So if direct mail is so inefficient, why use it? Because the financial inefficiency doesn't matter to the organization doing the fundraising. The end result of my hypothetical direct mail campaign is that my organization has $115,000 it didn't have before. That probably pays for one and half full time staff positions (at the low do-gooder wages we pay) for a year.

    So the ALS challenge was in the financial efficiency range of methods normally used by non-profits, albeit a little towards the inefficient end. That doesn't really tell us if the campaign was responsibly run or not; to know that you'd have to look at all the expenses and compare those to costs in other viral Internet fundraising campaigns. But the bottom line is that the ALS association ended up with $115 million it didn't have before.

    Can you think of a way of raising $115 million in a few months? I thought not. So presuming the guys who ran the campaign didn't spend the money on hookers and blow, I wouldn't be unduly concerned by a cost-to-raise-a-dollar of $0.91 if I was on the board.

    Should donors care that the ALS challenge was a little high on the cost-to-raise-a-dollar metric? Well, I look at it this way. People did it because it was fun and for a good cause, and two years later we can point to concrete and significant scientific results from the money raised. That's not only pretty good, it's pretty damned awesome.
