Chapter 8 Flashcards
General Systems Theory
Ludwig von Bertalanffy
A common framework for studying several similar disciplines would allow scientists and scholars to organize and communicate findings, making it easier to build on the work of others.
General Systems Theory
Input, throughput, output, evaluation, and feedback
Subsystems
General Systems Theory
material that enters a system
e.g.
School of Nursing System
Input
processes a system uses to convert material
e. g.
processes. Learning experiences
Throughput
measures the success or failure of the output
e.g.
NCLEX-RN and pass rates
Evaluation
information given back into the system to determine whether the purpose or end result of the system has been achieved
e.g
With high pass rates (established benchmark) – the system has achieved its purpose.
With low pass rates, the system may require changes – set higher admission standards, more talented faculty, and designing effective courses
Feedback
promotes the exchange of matter, energy, and information with other systems and the environment.
open system (hospital)
the larger environment outside the system
Supra-system
does not interact with other systems or with the surrounding environment
Closed system
is different from and greater than the sum of its parts (its subsystems).
The whole
occurs when all the various subsystems work together to create a result that is not independently achievable.
Synergy
A change in one part of the system creates change in other parts.
There is continuous exchange of energy and information
WITHIN open systems
BETWEEN open systems
Supra-systems
Dynamic balance within and between subsystems, systems, and supra-systems
Dynamic Nature of Systems
Dynamic balance within and between subsystems, systems, and supra-systems
helps create and maintain homeostasis (internal stability).
A system is a set of interrelated parts.
The parts form a meaningful whole.
The whole is different from and greater than the sum of its parts.
Systems may be open or closed.
All living systems are open systems.
Systems strive for homeostasis (internal stability).
Systems are part of supra-systems.
Systems have subsystems.
A change in one part of a system creates change in other parts.
Key Concepts about Systems
Human behavior is motivated by intrinsic needs.
Maslow’s Motivation of and Personality
required for a person’s well-being
Human needs
food, oxygen, rest, activity, shelter, and sexual expression
I. Physiologic Needs
reasonably predictable environment with which one has some familiarity and relative freedom from fear and chaos
II. Physical and psychological safety and security
close intimate relations, social relations, a place in the social structure
III. Love and belonging
need to feel self-worth, self-respect, and self-reliance
IV. Self-esteem
realized maximum potential
V. Self-actualization
Basic needs must be at least partially satisfied before higher-order needs can become relevant to the individual.
Individuals meet their needs in different ways.
The manner the needs are met and the extent by which these are considered needs vary according to each individual.
(Individualized nursing care)
Assumptions About Maslow’s Hierarchy of Needs
A person’s needs change as the person changes
Carl Rogers (1961) On becoming a Person
Adaptation theory
People admitted in hospitals and removed from their usual environments commonly become anxious.
Concept of adaptation
