Comment Re:But will they listen? (Score 1) 945

These persons (almost all of them self-proclaimed Democrats) act as if cops can do no wrong and any attempt to show otherwise is met with "You shithead!" and other insults.

That's odd, because it runs directly counter to my experiences, and to studies done on the sociological predilections of conservatives. Obeisance to authority is a conservative trait, not a liberal one.

I think you've either got a very unusual sample set for your observations, or you're full of shit.

I think the analytical and structural elements are more important. They are the parts, after all, that are universal to all types of writing.

I don't know what you're referring to as analytical and structural elements. You mean like the intro/body/conclusion of boilerplate high school essays?

I can't tell you how many English essays I wrote in high school that were funnel-intro, one paragraph per supporting concept body, and a conclusion that just mirrored the intro and body paragraphs. It didn't help me learn to write effectively, it taught me that I could apply a formula and get a good grade.

One of my history profs in high school taught me to write well. Make a point. Argue it completely, logically, and concisely. Refocus the reader on your point at the end.

I think your grading criteria need a little nudging. We should grade based upon what the intent of the exercise is -- in this case, the ability to convey and support an idea. This includes the elements of style (spelling, punctuation, grammar, etc.).

For example, if you took a written exam and made 15 punctuation errors, you should be ineligible to receive an 'A' (95%). That level of error suggests the writer does not understand how to use punctuation, which is a large barrier to ensuring your readers understand your points.

Spelling is less critical than punctuation -- misspellings do not generally obscure meaning.

I think the scoring should look something like this (on a 100-point scale, for a simple thesis paper ):

Thesis: 15 points maximum; points awarded for clarity in expression (style impacts clarity).
Supporting arguments: 60 points maximum; evaluated on logic, factual accuracy, clarity of expression, and significance to the thesis.
Summation: 25 points maximum; scoring based on clarity of expression of the thesis and consistency with the supporting arguments.

This grading scale would be for a class teaching composition, of course -- nowhere is mastery of subject knowledge evident in the grading. The reason we write theses and other essays is to communicate ideas and information. The scoring must therefore reflect how well the student communicated; style is sometimes critical to the communication of ideas.

people who don't take the time to spell things correctly are usually deficient in other areas such as grammar and writing clarity

I'm sure there's a class of people that are unable to spell correctly no matter how much time they have and how much of that time they apply to spelling accurately.

For that matter, faced with a written exam with a time limit -- people must decide how they use the limited time they have. Should I be rewarded because I am a champion speller, and can spend more time on the important parts of my composition, while others must devote more of their time to ensuring they spell correctly?

The other thing I'd like to add is that your perception of a correlation between poor spelling and poor grammar and clarity could present a problem -- graders who have that same perception are likely to grade exam-takers with poor spelling worse due to their bias against poor spellers. Maybe poor spelling has a greater impact on grading at high levels than you might suppose. Just food for thought...

As senator Al Franken not only ignored the majority of voters, who opposed health-care insurance reform, he ignored the Constitution of the USA too.

Oh, so now you've redefined the Constitution to make Senators and other elected officials just proxy voters for their constituents?

Senators are definitely not sworn to uphold the will of the majority of their constituents, which is a Damn Fine Thing, IMO.

Each extra pound of coal has significant and real costs associated with acquiring it.

Which includes, of course, some of the capital cost of the equipment used to receive the coal -- the wear-and-tear on that equipment does contribute to the length of its useful life. I think we're mostly talking about the difference between fixed and variable costs.

You could amortize the fixed costs over the total watts reflected over the lifetime of the mirrors and call that the 'fuel cost', but that's just not how normal accounting is done.

Sure it is, at the analytical level. Accounting feeds into the analytics. When you have a situation where the unit cost approaches zero, then the fixed costs dominate the cost side of the proifitability equation -- so the best way to increase unit profit (only looking at cost, of course) is to produce more with the same fixed costs. This is why the efficiency of the steam turbine, etc, is so important. You get more production out of the same fixed costs on the fuel side.

The thing is, fuel cost as the OP considered it (and as I think you're referring to) is meaningless. What matters is the COGS. That'll include the fuel cost, the cost of receiving the fuel, the cost of converting the fuel to usable energy, the cost of delivering the energy, etc.

The claim that efficiency is meaningless because the fuel is free just doesn't stand up -- the fixed costs are very important.

The fuel is not sunlight. The fuel is sunlight directed at the receiver. The cost of directing the sunlight at the receiver is part of the fuel cost.

In the same manner that the cost of fuel to a coal plant includes the cost of extracting and delivering the fuel to the plant, the cost of fuel for a concentrated solar plant includes the cost of concentrating that solar and delivering it to the receiver.

Fuel is free. Capital and maintenance costs are something that another power plant would have, in addition to fuel costs.

No, fuel is not free. Fuel costs include all the costs associated with acquiring the fuel. Marginal fuel costs are zero. But fuel costs are not zero in this case.

Besides which, we were talking about the potential of using this technology on a small scale, such as a backyard deployment. This makes your point completely extraneous.
