    I don't know, I have a very strong Bayesian prior that the drunk driver is the cause of an accident when that drunk driver is involved in an accident. Eyewitness testimony is fraught with possible errors so unless there is something stronger like video or a black box recorder I don't think you could convince me that the sober person was the cause of the accident (even with a preponderance of the evidence standard)

    But merely the existence of a cell phone near the accident should mean almost nothing - almost everyone will have one, but the vast majority of accidents that occur have nothing to do with a cell phone. So I don't think that the police should be able to just fiddle around with someone's cell phone just because 1) the phone is there, and 2) there was an accident. Of course, if an SMS pops up while the officer is there saying something like "what was that? you didn't finish that last text" then of course it becomes evidence, but this law seems to just be authorizing fishing expeditions.

The question at the time was "Whether a state rule of evidence allowing an expert witness to testify about the results of DNA testing performed by non-testifying analysts, where the defendant has no opportunity to confront the actual analysts, violates the Confrontation Clause." The majority held that it did not violate the confrontation clause, with these four justices in dissent.

    Is it 'management dickery' to have a dashboard camera to record police officers on traffic stops? Or to put a black box recorder in a commercial airliner? How about background checks for elementary school teachers? Surveillance cameras on bank tellers, or casino dealers? I'm all in favor of privacy rights for the general public, but there are certain professions that by their very nature require a higher level of scrutiny, especially on the job.

    This has been a problem for decades, and less intrusive methods have not seemed to solve the problem. Yes, this comes down to a "this is why we can't have nice things" argument. But of all the things that health care professionals do that requires hard work, sacrifice, a high level of skill, or dedication to helping people, this seems like such a small additional step with a tremendous possible bang for the buck.

    According to this, "it has been estimated that hospitalacquired infections are responsible for 80,000 deaths in the United States and 5,000 deaths in the United Kingdom." "Compliance rates were ... lower among physicians (32%)." So only 32% of doctors are washing their hands, killing 80,000 people per year. I will let the reader decide whether they want to compare this to the deaths caused by automobiles (32,367) or handguns (31,672), but apparently keeping hands clean in hospitals is a serious public health problem, and one that, of all people, hospital administrators, doctors and nurses should all be doing everything they can to fix it.

    The good news is that micromanagement works: "The majority of the time, the situations that were associated with a higher compliance rate were those having to do with dirty tasks, the introduction of alcoholbased hand rub or gel, performance feedback, and accessibility of materials."

    This isn't about monitoring bathroom breaks, it is about monitoring basic competence to do your job. A patient is supposed to end a hospital visit healthier than they started, and if health care professionals are doing things that make that goal more difficult then they are failing at their job. It's not the same as, say, monitoring the number of lines of code that a developer writes (where there is, at best, a tenuous relationship between the measured value and the quality of software - and probably none at all), it is a well-documented and serious problem that kills people. It's more like measuring whether a developer leaves his workstation turned off all day. Washing hands regularly is a necessary though not sufficient condition to make people healthy in a hospital, and if constant monitoring is required to get more than 1/3 of doctors to do it, then so be it.

    Though I detect a subtle distinction between GP and your post, you are both describing cash hoarding. But where I really differ with you is here:

    America has rock bottom interest rates and companies find it easy to hawk bonds to raise money – even junk bonds. So don’t worry about the Fed.

    I worry a lot about the Fed. Just because rates are low doesn't mean that monetary policy is loose enough. Let's check inflation:

    "Over the last 12 months, the all items index increased 1.1 percent before seasonal adjustment."

    1.1% inflation does not sound like the result of loose monetary policy. But macroeconomic data has all sorts of issues with it, so for some theory, let's go to the greatest monetary economist ever, Milton Freidman:

    Low interest rates are generally a sign that money has been tight, as in Japan; high interest rates, that money has been easy. source

    So the rock bottom interest rates that you refer to are indicative that money has been tight, when it should have been loose. Therefore I hold the Fed responsible and Apple (mostly) blameless.

    2 points: first, companies, just like individuals, may justifiably want to hold cash in order to deal with unexpected contingencies. In tough times, they want to hold more cash, and make less investments, despite the fact that it makes everybody worse off. That's Keynes 101. Now, Apple is probably taking it to an extreme, but given the rocky road they have gone through over their lifespan, maybe it is understandable that they want to have lots and lots of cash. Like how my grandmother who grew up during the Great Depression keeps a ball of aluminum foil so she can reuse the stuff - you know, just in case.

    Second, when there is cash hoarding going on, it is the responsibility of the central bank (in the US, the Federal Reserve) to ensure that there is sufficient cash being spent. There are different schools of thought here regarding the power or impotence of the central bank when rates are already near zero, but to assign moral responsibility to a company that is doing what it thinks it needs to do for the long-term benefit of its employees and customers during the slowest post-war recovery seems misguided. Better to assign blame to the few members of the Fed who have the power to loosen the money supply but refuse to do more, or blame the hard money crowd on the right that see hyperinflation right around the corner and create an atmosphere where the Fed has to walk carefully, or blame the president for not putting loose money advocates on the FRB earlier than he did.

I partially agree with your analysis on the first paragraph. But it is not merely babble. If you read it from the point of view of a limited-government conservative, who believes in an originalist interpretation of the Constitution, it is very important to tie the work of the NSF (or any part of government) back to justice, domestic tranquility, common defence, or general welfare. Therefore it is not merely vacuous - it is an important argument against the ~50% people who vote Republican and by pure chance will win ever other election (or so). In a democracy, it is best to convince your opponents rather than rely on out-voting them every single time, even if that means that you only get half a loaf.

    Fortunately, you are right that it is broad enough to drive a truck through. But that is no mere accident; basic research, even from a Republican perspective, is often an OK government expenditure if it is argued carefully and respectfully, and the spending is carefully tailored so as not to be wasteful. And that is the real point of this - not to deny funding to science, but rather to prove conservative bona fides and push conservative priorities in science. Will that mean fewer grants to climate science? Probably. But maybe more funding to DARPA battery research. In two or four years, the hands controlling the purse-strings will probably change, and priorities of the NSF will change as well, so it's tough to get too worked up about it. I would be more worried if the Republicans just said that they are cutting off funding to the NSF rather than saying, as they are, we are going to defund X and fund more Y.

    And honestly, if you were to ask me personally whether we need YACCS (Yet Another Climate Change Study) or a new DARPA challenge, I would rather have cool new robots!

    Subsidization between channels is actually a lot more complicated than people think. Assume that channel A is a popular station, and channel B is unpopular. Maybe 500,000 people watch channel A during the month and 10,000 watch channel B. Further, let's say that the cable company pays $20/month/subscriber for channel A and $5/month/subscriber for channel B. If you only watch channel B, then it seems like you are getting shafted, since it seems like you are paying $25 to only get $5 worth of benefit.

    But the problem is that the denominators typically used to present cost/subscriber does not take into account whether the subscriber watches the channel or not. So in the above case, if there are 1,000,000 total subscribers to the cable system, then channel A charges $20,000,000/month and channel B charges $5,000,000/month. If the channels were a la carte, channel A would charge $40/month to the 500,000 subscribers that want it in order to make $20,000,000 per month (40 x 500,000 = $20,000,000), and channel B would have to charge $200/month to each of its 10,000 subscribers.

Looking at it again maybe a Vector Autoregressive model is best. Or a VECM?

    R does have a lot of problems, among the worst is loop performance. It really forces you to vectorize everything, which leads to less maintainable code, and is generally a coding technique that new hires coming from other languages will face a steep learning curve with. What I have found useful is to use R as a data exploration and model parameterization tool, but once the model is ready to be put into production, you can use the parameters calculated by R in an implementation in the language of your choice, e.g., C++.
