Double Loop Control Theory by William T Powers

Geoff McDonnell
Double loop version of IM-8908 Based on 1990 SDR Article. Control systems act to make their own input match internal standards or reference signals. Competent control systems create illusions of stimulus response causality. Stimulus-response theory can approximate the relationship between disturbance and action, but it can't predict the consequences of behavior. These consequences are maintained despite disturbances. See also Double loop learning and Nurse Thinking Insights. See also IM-9273 for DLL LAIR model

Perfectionism at Work

Sid
in the beginning, expectations are normal for a new employee. By excelling, the employee builds goodwill, and immunizes self from criticism and accompanying shame. However, as time goes on, expectations rise until they first reach, and then exceed, the level of the employee's performance. This may be due to demands from multiple sources that are unaware of each other. It may also come about as completed projects add a layer of ongoing, and growing, maintenance. At this point, perceived criticism of the employee's performance occurs. Depending on the employee's potential for shame, which is likely high due to his/her use of this perfectionist defense, this criticism triggers shame, which then results in an avoiding (withdrawal, quitting) or controlling (secondary anger, irritability) defensive response.  Alternatively, the employee may choose effective action, setting boundaries and beginning to address the shame directly, separating it from  performance.

Bipolar II dynamics

Eduardo Enrique Escamilla
Bipolar II treatment modeling using Van der Pol-like oscillators.

In this simulation an afflicted individual with Bipolar II disorder is put to treatment after 20 months the calibration of the medicine or treatment he recieves is such that it simulates the natural cycles of a "normal being". You can note by manipulating the parameters that sometimes too much treatment disrupts equilibria. Also note that in the state diagrams there are 2 limit cycles, the lower one being the healthiest as there are less changes.

The dynamic that prevents confronting climate change

Hanns-Jürgen Hodann

The fact that we all strive to reduce psychologically inconsistent thoughts  is a well-researched phenomenon. When we hold two conflicting thoughts in our heads we feel an overwhelming desire to reduce this conflict. This desire can be a powerful driver in the way we behave. Most of us are aware at some level that if we took the threat of climate change seriously we would need to completely change our routines and the way we behave. Flying off on holiday would be out of the question. Swimming pools would be a past luxury. Most of us would need to give up our cars and become vegetarians. The list can be extended almost endlessly. Very often, subconsciously, we try to reduce troubling and inconvenient facts by minimizing, ignoring or even by denying them. Could this be why we hardly talk about climate change even in the face of increasingly frequent extreme weather events and obvious signs that it is occurring now?

This subject needs to be openly talked about between us and in the press. The seriousness of global warming makes it a necessity.  Only when this happens will politicians have the space and incentive to act on our behalf. But before this can happen we need to be aware of the reason why we avoid talking about this subject – this graph tries to illustrate the harmful dynamic that could be responsible for it.

Modelling Individual

Edwin Gary Schasteen
This model represents an individual as consisting of a brain coupled to an external environment. The brain will be modeled at a resolution of functional brain regions that are thought to be most important for effecting a person's learning in a classroom environment.

This model encodes both hierarchy relationships (brain and senses are part of an individual's body, which is, in turn, part of the environment), as well as causal relationships.

The hierarchy is containment and is represented by nested folders. The environment is modeled as a folder containing all objects of interest, including the individual's body as a whole system. The individual's body is modeled as a folder containing a brain and senses. The individual's body folder is contained inside of the environment folder to represent the idea that the individual's body is contained in, and is a part of, the environment.The brain object and senses objects are contained inside the individual's body folder to represent that the brain and senses together form an object and process that is internal to the individual's body (that is, is contained inside the individual's body and are part of the individual's body).
