Methods for kinematic modeling of biological and robotic systems.

The main objective is to develop methods that automatically generate kinematic models for the movements of biological and robotic systems. Two methods for the identification of the kinematics are presented. The first method requires the elimination of the displacement variables that cannot be measured while the second method attempts to estimate the changes in these variables.

Caregiver hardiness explored within Watson's theory of human caring in nursing.

Older family caregivers are often responsible for aged parents or spouses. The purpose of this theoretical article is to review the literature regarding the concept of hardiness, present a summary of Jean Watson's Theory of Human Caring in Nursing, explore older caregiver hardiness within Watson's theory, and discuss implications for gerontological nursing. An understanding of older caregiver hardiness within Watson's theory will guide gerontological practice, research, and theory development in nursing.
