Here's the thread about "membranes" as a metaphor for groups of people.
15/ One metaphor I've heard people use for regulating group dynamics is of a cell membrane

(what's my prompt again? "Spatial metaphors for human systems" ...idk what counts as spatial - everything's pretty spatial to me. I guess I'll avoid computer stuff tho\u2014doing great so far)
15a/ Membranes. Monists go on about how everything is one, which is true in a sense but also have you noticed that some things are inside and some things are outside? The role of skin, or the walls of a house, or a windshield on a car, is it keeps inside in & outside out.
15b/ Membranes can be applied to groups, and we can talk about a few different kinds of membranes that you might see around a particular group of people:
- closed membrane
- closed web
- semipermeable membrane
- open network
15c/ Closed Membrane: eg a company, family or country. Maybe a way to join it, but you need an active & explicit invitation by the members, whether thatās a job application or a marriage or an immigration process. Lots of intentional community houses are also like this.
15d/ Closed Web: consider a friend group. You don't exactly need an invitation from everyone in the group to join, but you do need to make friends with *someone* in the group. Polycules (except polyfidelity) work similarly, usually.
In January, we were featured in an article published by @StreetsblogMASS about the Central Section construction, which had just gotten
Also in January, the City of Westfield advanced a project to construct a spur off of the Columbia Greenway, connecting Country Club Dr to the Shaker Rd crossing.
We saw the old railroad bridges over Thomas, Chapel, and Orange Streets removed in March, in preparation for new ones to be installed as part of the Central Section.

As the weather got warmer through the spring, there was a large increase in trail users, with April seeing a 115% increase from the previous
Falls of Rome & Tang in 1st millennium were worse, but at least they were recorded. Records of the even worse Bronze Age Collapse around 1200 BC barely survived for some areas, & for other regions all we have are archaeological indications that they regressed to the stone age.
Bronze Age Collapse & resultant trade breakdown led to cession of bronze production in the Don River Basin. Locals reverted to stone & bone tools, then figured out how to make iron tools. Their neighbors adopted iron over the next few centuries. pic.twitter.com/HoDk52cLuH

Further back in the 3rd millennium BC, an even worse series of catastrophes occurred - the Indo-European invasions - ending the Megalith Builder Civilization with their urban settlements & leaving much of Europe depopulated for 600 years.
There are no traces of permanent Corded Ware settlements anywhere - strongly supporting that they were nomadic cattle herders. Only after Bell Beaker arrival in 2300 BC do sedentary agricultural settlements return. pic.twitter.com/GkPluSgbbt

By the time of their destruction the Megalith Builders themselves had been in a centuries long decline from their Golden Age in late 5th & early 4th millennium. Their great realms had likely disintegrated around 3500 BC into smaller chiefdoms engaging in endemic warfare.

The Megalith Builders themselves were the result of WHG chieftains overthrowing the decadent EEF chiefs like those of the Linear Ceramics around 4400 BC & subjugating an 1800 year old neolithic civilization. Possibly related to spread of copper-working.
Resurgence of Hunter-Gatherer ancestry in Copper Age Balkan EEF populations of mid 4000s & return of hunter-gatherers cultural customs. EEF Cucuteni\u2013Trypillians experienced this too - were 80% EEF, 10% EHG, 10% WHG in ancestry, showing they mixed with local HGs. pic.twitter.com/Tqf5yoc99U

A ššµšæš²š®š± on how mitigation works, why we probably need some level of carbon capture & storage (CCS) & carbon dioxide removal (CDR) - just not as much as in scenarios.
Based on my presentation ⦠https://t.co/j5uLxUi0xF
2. We start with a baseline or reference scenario, that assumes no or limited mitigation. If we want to stay "well below 2°C" we need to get rid of the dark grey & be net-zero!
We can argue about the baseline, but for the purposes here, it doesn't matter https://t.co/C0dAdj65tl
3. The heavy lifting is done by conventional mitigation: behavioural change, energy efficiency, fuel switching (fossils to non-fossils), changed transport, dematerialisation, etc, etc...
But, scenarios suggest this is not enough to get rid of all greenhouse gases.
4. In some sectors, particularly some industrial sectors, perhaps the cheapest or only way to mitigate is with carbon capture & storage (CCS), eg, cement, steel, chemicals, etc
This is one reason we need CCS...
5. We can't forget about non-COā emissions. We can probably get most non-COā out of industry, but what about agriculture? Even if we change diet, reduce food waste, etc, we may not be able to eliminate CHā or NāO from agriculture.
Some COā & non-COā remains (dark grey)...
1/6 Next thread re Air Policing is on Airborne Early Warning (AEW) aircraft (to follow on from Radar, QRA and tankers). Previously the domain of only the richest countries, an increasing number of nations are availing of AEW aircraft to act as another force multiplier. https://t.co/LUpi2bZYBY

2/18 Thatās before you get to the whole argument about twin engine vs single engine safety overwater argument. For now, itās enough to put forward the options in broad outline.
Option 1: Surface-to-Air missiles only
This option is included because thereās always someone...
3/18 ...who will say ājust get missilesā, because they think that this will be somehow cheaper. Modern long-range surface-to-air missile (SAM) systems, however, are not significantly less expensive than fighter jets. They also have an issue in how many times you can use them.
4/18 They have an even bigger issue in that your solution to what may only be an airliner with a broken transponder is to blow it out of the sky.
@ConorHogarty @mupper2 @kevpipps
5/18 While there are many good reasons why the @defenceforces should upgrade its SAM capability, these are largely related to the blended warfare now being rolled out globally with the increasing use of basic drones and larger unmanned aerial systems. @conormlally @RuthMCasey
The world is currently WAY over our #carbonbudget for where we need to be to align with #ParisAgreement. Orange= countries will do under any event; red = conditional (e.g., will do if they get needed finance). We have LOTSA emissions to reduce fast @davidwaskow @WRIClimate (2/n)
Of 21 indicators assessed for #ParisAgreement:
2 are on track (e.g., crop yields)
13 right direction but too slow (e.g., need electric vehicle sales to be 22x faster than now)
2 in wrong direction: forests, ag emissions
@davidwaskow from @climateactiontr, @WRIClimate et al 3/n
Current state of play: 12 Dec 2021= 5 year #ParisAgreement anniversary. Look for more announcements of national climate pledges. Some new pledges already released, but many govt's focused on #COVID19 recovery- important to link with climate-compatible recovery. @davidwaskow 4/n

And that means owning up to why Indian military assistance is needed. This requires large national conversation about the threat of Islamic extremists in the Maldives, explain the dangers and the opportunity cost of an attack etc. /2
People will except we'll reasoned decision making. And the public already has a frame of reference to indian military assistance from November 3rd 1988. So none of this is new or a surprise. /3
What is being weaponised is this imagined spectre of loss of autonomy for the country by collaborating with indian military on national security issues. This is an easy problem to solve. /4
The solution is merely laying out how national autonomy is maintained in such a national security collaboration. It's not like the Maldives can defend itself from any foreign military invasion anyways. /5
