Nursing theories frame, explain or define the practice of nursing. Roy's model sees the individual as a set of interrelated systems (biological, psychological and social). The individual strives to maintain a balance between these systems and the outside world, but there is no absolute level of balance.
While this approach was once deemed sufficient, contemporary research within psychology and the social sciences has cast doubt on its effectiveness. Scholars are now working on developing a broader health model, incorporating insights from psychology and social sciences, with the intention of improving its practical application in clinical ...
He observed multiple species of bees in order to investigate the different levels of animal sociality, many of which are different stages that a colony may pass through. Eusociality, which is the highest level of animal sociality a species can attain, specifically had three characteristics that distinguished it from the other levels: [1]
Charles Darwin considered the evolution of eusociality a major problem for his theory of natural selection.In The Origin of Species, he described the existence of sterile worker castes in the social insects as "the one special difficulty, which at first appeared to me insuperable and actually fatal to my whole theory".
The savannah hypothesis (or savanna hypothesis) is a hypothesis that human bipedalism evolved as a direct result of human ancestors' transition from an arboreal lifestyle to one on the savannas. According to the hypothesis, hominins left the woodlands that had previously been their natural habitat millions of years ago and adapted to their new ...
The theory of human caring, first developed by Watson in 1979, is patient care that involves a more holistic treatment for patients. As opposed to just using science to care for and heal patients, at the center of the theory of human caring is the idea that being more attentive and conscious during patient interactions allows for more effective and continuous care with a deeper personal ...
Human preferences toward things in nature, while refined through experience and culture, are hypothetically the product of biological evolution. For example, adult mammals (especially humans) are generally attracted to baby mammal faces with their large eyes and rounded features and find them appealing across species. Similarly, the hypothesis ...
