Madeleine Leininger (July 13, 1925 – August 10, 2012) was a nursing theorist, nursing professor and developer of the concept of transcultural nursing. First published in 1961, [ 1 ] her contributions to nursing theory involve the discussion of what it is to care.
Through Leininger, transcultural nursing started as a theory of diversity and universality of cultural care. Transcultural nursing was established from 1955 to 1975. In 1975, Leininger refined the specialty through the use of the "sunrise model" concept. It was further expanded from 1975 to 1983.
Human life expectancy is a statistical measure of the estimate of the average remaining years of life at a given age. The most commonly used measure is life expectancy at birth (LEB, or in demographic notation e 0, where e x denotes the average life remaining at age x). This can be defined in two ways.
The Lindy effect (also known as Lindy's law [1]) is a theorized phenomenon by which the future life expectancy of some non-perishable things, like a technology or an idea, is proportional to their current age. Thus, the Lindy effect proposes the longer a period something has survived to exist or be used in the present, the longer its remaining ...
This is especially true for Healthy life expectancy, the definition of which criteria may change over time, even within a country. For example, Canada is a country with a fairly high overall life expectancy at 81.63 years; however, this number decreases to 75.5 years for Indigenous people in the country. [4]
Life table" primarily refers to period life tables, as cohort life tables can only be constructed using data up to the current point, and distant projections for future mortality. Life tables can be constructed using projections of future mortality rates, but more often they are a snapshot of age-specific mortality rates in the recent past, and ...
The theory gained further credibility through the work of Raymond Pearl, who conducted experiments on drosophila and cantaloupe seeds, which supported Rubner's initial observation. Pearl's findings were later published in his book, The Rate of Living , in 1928, in which he expounded upon Rubner's theory and demonstrated a causal relationship ...
According to this theory, life span development has multiple trajectories (positive, negative, stable) and causes (biological, psychological, social, and cultural). Individual variation is a hallmark of this theory – not all individuals develop and age at the same rate and in the same manner. [15] Bronfenbrenner's ecological theory
