Over the past decade, the study of induced system resistance has become a very active field of research. [12] Methods to artificially activate the ISR pathway is an active area of research. [13] The research and application of inducing plant system resistance have been encouraging but are not yet a major factor in controlling plant pathogens.
ISR is the coordinated and integrated acquisition, processing and provision of timely, accurate, relevant, coherent and assured information and intelligence to support commander's conduct of activities. Land, sea, air and space platforms have critical ISR roles in supporting operations in general.
Indexing and classification methods to assist with information retrieval have a long history dating back to the earliest libraries and collections however systematic evaluation of their effectiveness began in earnest in the 1950s with the rapid expansion in research production across military, government and education and the introduction of computerised catalogues.
The Air Force ISR Agency was established as the United States Air Force Security Service (USAFSS) on 20 October 1948. [4] The service was headquartered at Arlington Hall , a former girls' school and the headquarters of the United States Army's Signals Intelligence Service (SIS) cryptography effort during World War II .

In statistics, efficiency is a measure of quality of an estimator, of an experimental design, [1] or of a hypothesis testing procedure. [2] Essentially, a more efficient estimator needs fewer input data or observations than a less efficient one to achieve the Cramér–Rao bound.
The ISR's organizational structure consists of a board of trustees and an advisory council. The Board of Trustees consists of prominent leaders in the United States and across the Atlantic. The ISR's research programs and management are implemented by fully abiding the U.S laws and being transparent to the public.
