Q

General Systems Theory (GST)

A

Ludwig von Bertalanffy

Ol’Bert felt we needed a common theory to guide research in mult. disciplines that did not communicate well

So, he made a common framework, where scientists from many disciplines, could better communicate their findings with each other and build upon each other’s work

Gives us and Lets us see interconnectedness

Q

How does GST connect to nursing?

A

Nurses are enmeshed in many different systems (patient, families, communities, work place) so we can effect change if we understand how all these different systems work with each other all at once - rather than view them isolated from one another

Q

What is a system in GST?

A

a goal directed unit made up of interdependent parts that interact and endure over time

These elements have a relationship that can be theoretically demonstrated

the system can also maintain organization in the face or change from either within or out - and if it cannot it will fail/implode

Q

What are the most important things occurring in GST?

A
  1. One thing effects another
  2. Events and existence occurs in relation to other circumstances - no causative vacuums
  3. Systems are dynamic and want to adapt to change to maintain integrity

Q

What is the structure of a system?

A

The structure is based on the arrangement and organization of the parts making up the system. So, the parts are interrelated, interdependent, and function together to maintain the whole

Q

Example of System Sizes

A

Community (Suprasystem) > Family (Focal System) > Person (Subsystem)

Q

What can occur if a boundary is too permeable or not permeable?

Boundaries demonstrate how systems must always be in a state of ...
growth and change
26
Examples of Variables that can Influence Boundaries
``` Experiences Security Physical Safety and health Self identity Comfort Level personal boundaries ``` Different factors can either make boundaries more or less permeable
27
Types of Systems
Open or Closed
28
Open System
Healthy System Interacts with the environment which is needed for survival Capable of growth, development, and adaptation
29
___ is necessary for open system survival
Interaction
30
Closed System
Unhealthy Isolated from environment Fixed, automatic, relationships among system components Little growth opportunity
31
Principles of an Open System
All Systems respond as a whole All parts/systems are interconnected Ripple effects occur Nonsummativity cause and effects are interchangeable
32
Ripple effects in systems
change in one part causes changes in another - it can GREATLY impact other systems it influences ex: Improved water --> better life quality --> better child development --> Better economy, food security, etc
33
Nonsummativity
the whole system is greater than the subsystems/sum of its parts (every sub interacts with and has effects on other subs) No part acts without consequences for other parts Each part's action affects not only the system, but also all the subsystems and environment/suprasystem Whole > Parts
34
Another term for Ripple Effect
Reciprocal Determinism
35
Another term for Nonsummativity
Holism
36
Input
Exchange of information, energy, or resources into a system through the boundaries It is the raw material that the system will transform It is used to maintain the system and make outputs
37
Examples of Input
Information Money Raw Materials Energy
38
Boundary Control
the degree of permeability of the boundary determines how much input gets into the system or output gets out Degree of exchange regulates amount and type from environment, so equilibrium is maintained in the system
39
Throughput
The processes used by the system to convert inputs from environment into outputs useable by the system or environment
40
Examples of Throughput
Critical thinking Physical Exam of patients Planning Decision Making
41
Output
Product or Service resulting from the systems throughput of the input Products an open system releases into the environment and can re-enter the system or other systems as a new input form
42
Feedback and Systems
Communication/Feedback are important because they refer to output that is available to the system in ways that allow it maintain stable functioning. q
43
How can systems use feedback to adjust?
Internally - modify subsystems Externally - modify boundaries
44
Feedback Loops
Path where info can be traced from one point in a system through one or more other parts / or its environment, and back to the point of origin 2 types: positive and negative
45
Negative feedback loop
loop provides information that returns the system to a preset level and reduce deviation causes to the system homeostatic system
46
Positive Feedback Loop
tends to promote change in the system
47
Example of the Hospital experiencing feedback loops with money, humans, info, material, time, and equipment as inputs?
Processed --> Better health and QOL (which feedback to the inputs)
48
All dynamic and open systems require continuous supplies of ___ in sufficient quantity so demands can be met
energy (we need it and need it to not deplete)
49
The amount of energy needed by a system is governed by ...
rate of utilization of the energy within the system itself
50
Entropy
process of energy depletion and disorganization that moves the system toward chaos ENERGY DEPLETION for a system
51
Negentropy
process of energy utilization that assists system progression toward stability and promotes order in the system WE WANT THIS KIND
52
Equilibrium
Maintaining balance between negentropy and entropy A dynamic balance that is always changing through feedback systems It is a steady state resulting from the self regulation or adaptation
53
Homeostasis
State of balance between parts of a system sought by living systems Parts may be disrupted by action from within or without The system that is homeostatic will grow and lead, its ability to adapt increasing as a result, but too much flexibility will cause instability and function disruption ex: As decker students we adapt to the stressors on us
54
Difference between Equilibrium and Homeostasis?
Equilibrium occurs between systems while Homeostasis occurs within a system
55
Differentiation
Tendency of a system to actively grow and advance to a higher order of complexity and organization Since complexity increases (ex: Infant --> Adult) a balance is needed between stability and change to continue growth and differentiation
56
Equifinality
Same endpoint can be reached from many different starting points (many ways to the same goal) All Systems operate on this principle An open system will be able to maintain a steady state from many different means to reach the goal state
57
Goal (GST)
Overall purpose for existence of the system or the desired outcomes of system interaction the reason for being currently many organizations put their goals into a mission state (ex: our goal is to become nurses by choosing decker)
58
A balance between stability and change
equilibrium
59
Same endpoint can be reached from different starting points
equifinality
60
Whole is greater than the sum of its parts
Nonsummativity
61
Energy that promotes order in a system
Negentropy
62
Process which acts to restore homeostasis by inducing changes in the opposite direction of a force impacting a system
Negative Feedback
63
First step of the community assessment is the ...
windshield survey
64
"Community as Client" means...
focus is not one-to-one, but rather the larger community Involves making a community diagnosis through investigation of major health and environmental problems via surveillance, monitoring, and evaluation of community health status
65
What diagram is used during each windshield survey?
The community as partner model Core, Recreation, Physical Environment, Education, Safety and Transportation, politics and government, health and social services, communication, economics
66
Qualitative Data

67
Quantitative Data
Part of the windshield survey observations ex: census demographics, vital statistics, housing information, local services and agencies, phone book, websites, observations via windshield survey
68
What kind of data is the windshield survey gathering?
quantitative data
69
Windshield Survey
actually driving through a community and OBSERVING different aspects that impinge on the health of a community it is a way of getting a quick, initial sense of the community as based on the community-as-partner model
70
