Animal Aggregate Researcher- Sort of
Jens Krause. Says
he’s interested in the mechanisms and functions of group living in
animals. The term ‘group living’ is another new term. I think it indicates
that he is not as interested in the short term group movement patterns of
animal aggregates as he is in the social, long term, effects of living in
groups.

Researcher into modelling biological populations
Mark
Broom. He’s a mathematician, but he has collaborated with a wide
variety of biologists, including ones doing fish schooling and group
behaviour research. His page also mentions G.D. Ruxton, who does animal
aggregate research at the University of Glasgow, but doesn’t have any web
presence that I can detect.

Boggle
I’m still working away on my environmental consulting stuff. As May and
Dan will attest to, some of my experiments have been more successful than
others- the brown industrial paper towels get a thumbs down, the scratchy
but functional recycled toilet paper gets one thumb up and one down, at
least from me…
In any case, looking for a list of common househould objects to use for developing a spreadsheet, I came across this extensive but highly daunting list from CHEC. Man.
Honestly, I don’t
want to scare the hell out of people to get them to be environmental.
That’s why I’m supremely conflicted about the whole “your health will be
damaged unless you go green” angle. I think one of the big problems is
that, as far as I know, there is no hard core, well done research studies
around to back this stuff up. That means that I couldn’t say to someone
something like, “Do this, and your risk of cancer over the next five years
will DECREASE by 10%.” Or “Do this and your lung capacity will IMPROVE by
3% in the next year”. And I am totally against the ‘negative message’
alternative, which amounts to running around madly shaking household
objects at people and squawking “carcinogen! carcinogen! carcinogen!”. I
tried that when I was thirteen, with bad results. People just don’t need
the stress.

Finally- a flocking guy
It seems impossible that no ornithologists has ever studied flocking
behaviour in birds, but I have been having a really hard time finding any
papers about this. I finally found one person

who has written some papers on flocking behaviour.

Origin of environmentalists
I’ve been doing more background research on animals that exhibit aggregate
behaviour and I keep seeing, in bios and home pages, something along the
lines of “When so and so was a certain age, they liked to watch [insert
animal here]. They eventually became a
conservation ecologists/conservationist/environmentalist because they
noticed that the number of [said animals] that they saw was getting fewer
and fewer.
This
person is a great example of this, I think.
The reason I find this interesting is that I know that I don’t have enough
connection with any animals in nature to be able to tell when their
numbers are getting fewer.

Fat is good.
As I was scrounging around the kitchen today I came to the conclusion that
our bodies are highly optimized for detecting, seeking out and consuming
fats and oils. We love them! Consider the following two choices:
A
bowl of pasta, canned tomatoes, and brown sugar, heated.
A bowl of
pasta, canned tomatoes, brown sugar and olive oil, heated.
For me, the first makes me go… blah. And the second makes me go…. hmmm could be good. Add a bit of salt and some oregano and you’re all set.
When I think about these things, I also think- our bodies can’t really be that stupid. Which is why this article made me very happy. According to the article, some researchers discovered that your body has a very hard time absorbing certain nutrients, like beta-carotene, unless you eat the foods containing these nutrients at the same time as eating some fat. More precisely:
“Researchers say this study shows
that the minimum amount of fat required for optimal absorption of these
nutrients from the salads is more than 6 grams of added fat. But because
salads are often consumed with other items that contain fat, the use of a
reduced-fat salad dressing may still allow the body to reap the maximum
nutritional benefits of fresh vegetables.” Of course, they had to add that
extra bit in there so people didn’t just go crazy with the dressing, but
still, I say- bring on the dip!

How Many Repetitions?
So, I must let the cat out of the bag… Colin bought me an engagement
canoe! Yaaay! I’m in love! With the canoe! And with Colin, of course! :)
But now, of course, I must truly live up to my goal of being able to lift a canoe. And not just lift it, but lift it and swing it through the air and up over my head and down again so that its yoke comes to balance delicately and precisely on my shoulders. At a measily 55 pounds, how hard can it be?
I guess it’s time for a little bit of weight training. I think
I’ll start by trying to figure out
how many repetitions are required, and go from there.

Paper towels? But wait!
Some thoughts on
paper
towel use from
The Teva Learning Center- ”
North America’s foremost Jewish Environmental Education Institute”. I like
the sponge idea, although you’d have to be fairly proactive about rinsing
it out. I also like their last line: ”
So now when something spills, whether it be your organic soy milkshake, or
your mothers borscht that just happens to slip out of your hands, there is
no need to feel any environmental guilt.”

Bleaching Timeline
An interesting history of bleaching.
In particular I find it interesting to note the closely but for much of
history probably unintentionally linked roles of whitening and sanitizing.
This would go back even to sun-bleaching, because a long enough exposure
to direct sun kills germs.

Disinfection Byproducts
One of the big problems with disinfectants in the water is the innocuous
sounding ‘disinfection byproducts’ or DBPs. Often these DBPs turn out to
be… carcinogenic organic compounds. Great! I know that ozone is
considered to be a promising new disinfectant so I was interested in the
DBPs produced by ozone disinfection. I found
this
interesting abstract about the DBPs produced when both chlorine and
ozone are used to disinfect water.

Our friend chlorine- not.
I’m having this dilemma because I think using things like handkerchiefs is
a good idea, environmentally speaking, but maybe not such a good idea from
the pathogen passing perspective. The problem is that ordinary laundering
doesn’t actually kill germs that effectively, which is particularly
problematic if you have a rampantly infectious cold. Unfortunately,
chlorine also seems to be chlorine
right out, as far as environmentally and health-friendly
solutions go.

Why do nurses complain?
If you would like to know, check out Making Good on
Private Duty: Practical Hints to Graduate Nurses, by Harriet Camp
Lounsbery. I’d really like to know when this was written. After the
invention of refrigerators, in any case. My favourite quote:
“I must not forget to say that when you go to see your prospective patient, and she shows you the room she expects to occupy, it would be well to cast your eyes about for some rug, that you can, if necessary, turn wrong side out and spread at the side of the bed. Some doctors are very neat about their work, but some are — well, perhaps I better not say it; we must not criticise the doctors.
But sometimes it is best to have protection for
the floor, it gives the nurse a comfortable feeling quite beyond
description to know, that, no matter what may happen, the carpet will not
be ruined.”
