I'm not familiar with the circumstances of those attacks, so I can only
speculate (based on our general knowledge about shark attacks) that they
were probably provoked by the victims or the victims were at the wrong
place at the wrong time and failed to exercise precaution/retreat to
prevent such attacks.

Therein lies the difficulty of documenting these cases for lack of first-
hand (and perhaps even reliable eye-witness) accounts.  I don't mean to be
insensitive to the tragedies or make light of the matter, but it seems
entirely possible that the victims unwittingly wandered into tiger-shark
banquets and instead of leaving discreetly immediately, turned their
uninvited-guest status into items on the shark menu.

Buy the Dec. Issue of Ocean Realm and read the shark article.  It's an
excellent article written for the layman by a marine biologist specializing
in the behavior, ecology, and history of sharks.  The article gave many
useful, valuable tips on the sharks' body language, their expected behavior,
and how we (as uninvited guests in their natural environment) can avoid
confrontations in which we may deteriorate from observer to bait.

To whet your appetite (no pun intended) a bit, here's how the author of the
article introduced the visitor/host analogy in (Clever Primate)/sharks:

   When we hire a car in London or Sydney, we do not try to eliminate
   all those who continue driving on the left-hand side of their roads;
   we recognize that we are the visitors and do our best to conform to
   their way of doing things.  That's part of the fun of visiting other
   cultures.  So why, when we seek recreation in an environment that is
   foreign to our species, do we insist that the residents obey our
   rules (Thou Shalt Not Bite a Clever Primate)?  I would like to
   propose an alternative to "punishing" all sharks for the unintentional
   "crimes" of a very few:  if we are going to continue entering the
   sharks' domain, rather than clearing the sea of sharks, it makes much
   more sense to become familiar with the ways of the sharks -- to become
   "Shark Smart."

Hi Bob
Well, first thanks for the corrections of the misspelled of the blue & big whit
e, although the s`s of the white sounds more sharky then the c`s :-)
I also think about the same as far as us humans invading into the sharks domain
. My comment is about the difference of what so called invading:
I think that there`s a big different when a person enters as a swimmer without
any observation what`s going on under the water, and with its strokes that is b
eing sensed by a potential shark, and a diver, that has more capabilities and a
bility to "act in Rome as a Roman".
True that some sharks are shy and can be petted - without any connection to the
ir mesurments - i.e whale shark.
But some others, are truly dangerous and observation is safe with metal suit or
 a cage, or neer the reef (hammerheads schools or some black tips etc.)
Back to the swimmers - the beaches should be protected by fences like in Austra
lia, and the swimmer will know that he is taking a risk while entering unprotec
ted waters.
I am against the hunt of the shark, since i belive its the nicest creature on e
arth.

I second this motion!!  Pauls mail does beg the question "Have you actually
been trained in compressor fuctionallity and operation?"  I sincerly hope
so.  If you have not why are you using it??!!!  and if you have why have
you not contacted your service company to get this rectified (if it is
caused by something else apart from the above).

It seems to me that if you are filling tanks that someones life will depend
on you should have a better knowledge of the equipment that you are using!!

To which I reply...

The type of compressor we are talking about here is a Bauer Capitano or
Mariner. This machine uses an oil known as Anderol 500. This oil WILL
circulate to the high pressure final stage piston. This piston is lapped
to fit the cylinder and does not carry compression rings. I also believe
that this is a floating piston not physically connected to a connecting rod
but is pneumatically driven by a "slipper" below it. The oil mists in the
air mixture and lubricates this stage as one might expect a two stroke engine
to be lubricated. (there is a pump also and spreader rings on lower stage
pistons).

        Now, to separate this oil (and moisture) from the air, a water trap
style of tower is used. Larger compressors will have several of these.
The tower is drained from the bottom periodically, and water/ oil will run
out. The white substance referred to is oil "whipped" into a greasy emulsion.
In Australia the oil is often darker due to higher running temperatures.

        Ok, Bauer compressors also have filters. Triplex filters are designed
to remove oil, moisture, and CO from the outflowing air. They can be weighed
to determine if excessive oil particles are travelling through. These filters
are designed to be replaced after x SCF of air has passed through them,
(usually determined by hours of running) OR if the filter is overweight on
inspection. These filters may be used in series with activated charcoal as
well.

        Of course, oil should be drained and replaced periodically according
to a service schedule, and replaced with only the recommended oil.

        I am unfortunately having to SIGNOFF from this list soon, as I am
a lowly student and will soon be 2-3 months between semesters. I hope to
hear from you all again approx. mid FEB '93.

Subject:      Monastery (Mortuary)

        I just talked with a friend on the phone who had a near death
experience diving in Monterey with Wet Pleasure (she was taking an advanced
class) and apparently the conditions deteriorated very quickly (heavy surf) and
the 'Instructor' didn't clue in on this  and tried to hold the class anyway.
There were some other classes finishing up at the time the advanced class
started; the instructors for these classes were busy getting their students out
of the water and were incredulous that Wet Pleasure (kurt) was even going in.
I guess this was one of those days that give this area the rep for being a
really hairy shore dive, (Nov.22 about 11:30am).
        Anyway, the 'Instructor' and his buddy (a divemaster) and also his
girlfriend, head in first- the 'Instructor' makes it past the surf line but his
buddy isn't so lucky and gets seperated
from him and otherwise folded, spindled and mutilated but eventually crawls
back to the shore, praising God and Man for her second chance at life. The
'Instructor' now without a buddy, screams for the next pair (my friend and her
boyfriend) to haul ass into the surf and to swim like their lives depend on it.
So they head out and the same thing happens -  he makes it (he loses his mask
in the process) and she doesn't. The way she tells it is that she got stuck in
the surf and it wouldn't let her go; it sucked her mask off, it ripped the
mouthpiece from her regulator off the reg. and it filled her secondary rig
with copious amts. of sand rendering it useless. It took three people to pull
her out on to the shore where she spent the next 15 minutes alternately
throwing up and crying.
        I guess the point of this whole post is that in searching for good
instruction (like good equipment); look long and hard, spend the most you can
afford and think of it as an investment in your own life etc. Or maybe it was
just to caution everyone out there about this guy at Wet Pleasure...

  Paul, what do you mean by "..one of the air valves.."?  I assume you don't
mean one of the hoses you attach to the cylinder to fill it.  If you have an
oil-like substance, or any substance other than air, coming from these, I
would assume that you stopped using the compressor immediately and warned
anyone who had a tank filled off that compressor in the last few months.
  I am not very familiar with larger high-pressure compressors like you are
using.  I am more familiar with the smaller models typically used for
construction (in the 70-150 psi or 5-10 kilos per square centimeter range).
These had a chamber where moisture, etc, in the air could collect and settle
to keep it out of the air-powered equipment.  It had a small valve on the
bottom that one could turn. The compressed air in the chamber would blow a
foul grey, black, or brown, thick oily substance out.  When the goop was
purged, you just closed the valve and were back in business.  It works much
like the sediment bowl or fuel/water separator on an engine.


No not the one I fill the bottles with,Its one of the blow off valves like you
mentioned .The reason that I got a bit worried is that it only ever used to
blow out a white gloopy substance which I assume is moisture.Its not as if I am
living in a heavy industrial area. :-)
Thanks for the information

The November 11th issue of the Chronicle of Higher Education (it is the
issue which reports on the results of the election) has an article about
libraries (in Colorado I believe) that have a networked system which lists
all the journal holdings.  A user requests a copy of an article for
$6.50 plus whatever the copy and transmission costs might be.  If there
is a copyright fee, that will also be included.

Has anyone used this system?  How satisfied are you with it?

Numa, is this one of the distribution systems that Pergamon will explore?

The description of lexical decision time studies is very
much appreciated, thank you.  As I understand it so far,
experimental subjects press a button when they understand
the lexical item, or maybe it is a particular button from
an array of choices or something like that?  If so, what
are the choices-- pictures?  L1 matching terms?  Is it assumed
that L2 mental lexicon will be simply a new set of points whose
loci are analagous to the set of points in the L1 lexicon?  Could
the new set of points be markedly different or distinct from the
L1 set?  Can L2 only be tested in reference to L1?

What kind of a mental lexicon, or stylicon, is expressed when
an L2 learner immediately comprehends a new word precisely
because the situation is deftly manipulated by a "guide".
For example, opening the window on a winters day, and
exclaiming "It's cold."  I'm wondering how the mental ____-con
can be constructed to account for general vicinity,
semantic overlap, and "close" guesses, all of which
seem to be integral parts of the L2 language learning
process, and initial boundary-marking in the mental map
of the target language.

Perhaps I am just being a bit feisty, but I think that
a mental lexicon which leaves out(and purposely) discourse
elements runs the risk of being a very precise of something
which just isn't really language.  Oh, well.  Think I'll
stop for now.  I am learning a lot from this discussion of
the mental whatever-con, and look forward to tomorrow's
additions.

This is but anecdotal support for episodic memory in L2 acquisition.  A friend
of mine who had good control of English at the time of this exchange told
me that she found that it was very useful to focus on the situation when a
new vocabulary word or phrase came up in which the meaning was made obvious
by the situation.  She said she used to repeat the word or phrase over and over
again to herself while she was still in the situation, attempting to make the
link between the word or phrase and the situational context a strong one.  She
said that this method had always proved very beneficial to her, and she thought
it was because it allowed her to attach the word or phrase to the feeling of
the situation, as well as to the more objective aspects of the situation.
However, it is unclear at what point in her English proficiency she came upon
this procedure.  From an information-processing point of view, certainly she
would have had to have automatized several linguistic procedures in order to
have the working memory space to focus on the social aspects of exchanges.
That is, without a somewhat sophisticated control of the linguistic features of
the language, she would not have been able to recognize the words or phrases
in the flow of communication to begin with!  It appears that the question is
how sophisticated one's linguistic abilities need to be before social aspects
related to linguistic information can be recognized.
