The nursing model is a consolidation of both concepts and the assumption that combine them into a meaningful arrangement. A model is a way of presenting a situation in such a way that it shows the logical terms in order to showcase the structure of the original idea. The term nursing model cannot be used interchangeably with nursing theory.
Mortimer Alan Rogoff (May 2, 1921 – August 1, 2008) was an American inventor, businessman, and author as well as an amateur photographer and radio operator. He is recognized for his work in spread spectrum technology which is the technology that modern cell phones and GPS systems are based on. He is also considered the grandfather of the ...
Moreover, for a given noise power spectral density (PSD), spread-spectrum systems require the same amount of energy per bit before spreading as narrowband systems and therefore the same amount of power if the bitrate before spreading is the same, but since the signal power is spread over a large bandwidth, the signal PSD is much lower — often ...
Direct-sequence spread-spectrum transmissions multiply the symbol sequence being transmitted with a spreading sequence that has a higher rate than the original message rate. Usually, sequences are chosen such that the resulting spectrum is spectrally white. Knowledge of the same sequence is used to reconstruct the original data at the receiving ...
Frequency-hopping spread spectrum (FHSS) is a method of transmitting radio signals by rapidly changing the carrier frequency among many frequencies occupying a large spectral band. The changes are controlled by a code known to both transmitter and receiver .
One of the founders of the sociology of health and illness is Talcott Parsons, an American sociologist, who analyzed the relationship between patients and their doctors in his book The Social System written in 1951. In his sick role theory, [9] he argued that people who were sick adopted a social role, not just a biological condition. Those who ...
The diffusion of innovations according to Rogers. With successive groups of consumers adopting the new technology (shown in blue), its market share (yellow) will eventually reach the saturation level. When the first edition of Diffusion of Innovations was published in 1962, Rogers was an assistant professor of rural sociology at Ohio State ...
In educational technology, Lindy McKeown has provided a similar model (a pencil metaphor [4]) describing the Information and Communications Technology uptake in education. In medical sociology, Carl May has proposed normalization process theory that shows how technologies become embedded and integrated in health care and other kinds of ...
