The two sleeps or They myth of the 8 hour rest

Much like the experience of Wehr’s subjects, these references describe a first sleep which began about two hours after dusk, followed by waking period of one or two hours and then a second sleep.

“It’s not just the number of references – it is the way they refer to it, as if it was common knowledge,” Ekirch says.

During this waking period people were quite active. They often got up, went to the toilet or smoked tobacco and some even visited neighbours. Most people stayed in bed, read, wrote and often prayed. Countless prayer manuals from the late 15th Century offered special prayers for the hours in between sleeps.

And these hours weren’t entirely solitary – people often chatted to bed-fellows or had sex.

A doctor’s manual from 16th Century France even advised couples that the best time to conceive was not at the end of a long day’s labour but “after the first sleep”, when “they have more enjoyment” and “do it better”.

Up until the 17th century, people in Europe tended to sleep in two cycles, a first short cycle of a few hours, followed by a period of wakefulness, then followed by another period of sleep.

World Bank Chief Economist, 1991: Let’s move polluting industries to less developed countries

DATE: December 12, 1991
TO: Distribution
FR: Lawrence H. Summers
Subject: GEP

‘Dirty’ Industries: Just between you and me, shouldn’t the World Bank
be encouraging MORE migration of the dirty industries to the LDCs [Less
Developed Countries]? I can think of three reasons:

1) The measurements of the costs of health impairing pollution depends
on the foregone earnings from increased morbidity and mortality. From
this point of view a given amount of health impairing pollution should
be done in the country with the lowest cost, which will be the country
with the lowest wages. I think the economic logic behind dumping a load
of toxic waste in the lowest wage country is impeccable and we should
face up to that.

2) The costs of pollution are likely to be non-linear as the initial
increments of pollution probably have very low cost. I’ve always though
that under-populated countries in Africa are vastly UNDER-polluted,
their air quality is probably vastly inefficiently low compared to Los
Angeles or Mexico City. Only the lamentable facts that so much pollution
is generated by non-tradable industries (transport, electrical generation)
and that the unit transport costs of solid waste are so high prevent
world welfare enhancing trade in air pollution and waste.

3) The demand for a clean environment for aesthetic and health reasons
is likely to have very high income elasticity. The concern over an agent
that causes a one in a million change in the odds of prostrate cancer
is obviously going to be much higher in a country where people survive
to get prostrate cancer than in a country where under 5 mortality is
is 200 per thousand. Also, much of the concern over industrial atmosphere
discharge is about visibility impairing particulates. These discharges
may have very little direct health impact. Clearly trade in goods that
embody aesthetic pollution concerns could be welfare enhancing. While
production is mobile the consumption of pretty air is a non-tradable.

The problem with the arguments against all of these proposals for more
pollution in LDCs (intrinsic rights to certain goods, moral reasons,
social concerns, lack of adequate markets, etc.) could be turned around
and used more or less effectively against every Bank proposal for liberalization.

This is old, but I came across it and figured I’d better share. This type of thinking, while somewhat under “wraps” now a days still exist. The final paragraph is especially tasty: “The arguments against more pollution in LDCs could be […] used more or less effectively against every Bank proposal for liberalization”

My container farm – phase 1

So, there’s this guy named Dr Doshi in Mumbai. Apparently he grows a ton of things on his terrace, and he’s written a couple of passionate books on the topic. When I got interested in how you could produce food, and especially how you could recycle your food waste and use it as a basis for growing your own food, I found his instruction manuals and figured I’d want to try his method out. This weekend and last, I finally got around to collecting all materials and get started. Basically all you need is – bags or other containers, some biomass, compost, soil, water and of course seeds. In this first phase I prepared the bags so that I can sow next week. Here’s the recipe :

 

1. Get your sacks

 

I used cement bags. Rice bags, fertilizer bags, buckets or anything like that which is easily and cheaply (or even freely) available would do. Open up the closed end, so that it becomes a tube so that it will drain water properly.

2. Fill the bottom 50% with biomass

 

I used straw which I could get from the local fruit vendors (they use it to pack their containers). Leaves, twigs, sugarcane from juice vendors or anything of that sort should also work. Whatever is available. This layer is for good drainage while still holding the compost and soil in its place

3. Add compost, 25% of what’s left

 

I started with the compost that i produced from my own food waste. Since I mix my food waste with leaves, and since there’s a lot of heavy-duty biomass (like mango pips) I put this in the bottom layer with the other biomass. In this way it’s given even more time to decompose as well as serve as a useful biomass layer. After that I filled up with gobar or cowdung compost which I’d got cheaply from local nurseries.
