The value of 4.0 g-cm/ml (= 2s) is discussed as a limit to a pathological increase. With a rise in breath volume, relative weight and also, marginally, the spontaneous resting breath frequency, a significant increase of ventilatory work of breathing in normal persons must be anticipated.ith a rise in breath volume, relative weight and also, marginally, the spontaneous resting breath frequency, a significant increase of ventilatory work of breathing in normal persons must be anticipated.
Family Systems Theory. The family systems theory is a theory introduced by Dr. Murray Bowen that suggests that individuals cannot be understood in isolation from one another, but rather as a part of their family, as the family is an emotional unit.
Ecological systems theory. Ecological systems theory, also called development in context or human ecology theory, identifies five environmental systems with which an individual interacts. This theory provides the framework from which community psychologists study the relationships with individuals' contexts within communities and the wider society. Ecological systems theory was developed by Urie Bronfenbrenner. The theory is also commonly referred to as the ecological/systems framework.
