1952 publications, he worked over the meaning and placement of each word in a collection of Quechua legends with a native speaker of Quechua and was able to formulate discourse rules that transcended the simple sentence structure. He then applied the process to Shipibo, another language of Eastern Peru. He taught the theory at the Summer Institute of Linguistics in Norman, Oklahoma, in the summers of 1956 and 1957 and entered the University of Pennsylvania to study with Harris in the interim year. He tried to publish a paper Shipibo Paragraph Structure, but it was delayed until 1970 (Loriot & Hollenbach 1970). In the meantime, Kenneth Lee Pike, a professor at University of Michigan, Ann Arbor, taught the theory, and one of his students, Robert E. Longacre developed it in his writings. Harris's methodology disclosing the correlation of form with meaning was developed into a system for the computer-aided analysis of natural language by a team led by Naomi Sager at NYU, which has been applied to a number of sublanguage domains, most notably to medical informatics. The software for the Medical Language Processor is publicly available on SourceForge. In the humanities In the late 1960s and 1970s, and without reference to this prior work, a variety of other approaches to a new cross-discipline of DA began to develop in most of the humanities and social sciences concurrently with, and related to, other disciplines. These include semiotics, psycholinguistics, sociolinguistics, and pragmatics. Many of these approaches, especially those influenced by the social sciences, favor a more dynamic study of oral talk-in-interaction. An example is "conversational analysis", which was influenced by the Sociologist Harold Garfinkel, the founder of Ethnomethodology. Foucault In Europe, Michel Foucault became one of the key theorists of the subject, especially of discourse, and wrote The Archaeology of Knowledge. In this context, the term 'discourse' no longer refers to formal linguistic aspects, but to institutionalized patterns of knowledge that become manifest in disciplinary structures and operate by the connection of knowledge and power. Since the 1970s, Foucault's works have had an increasing impact especially on discourse analysis in the field of social sciences. Thus, in modern European social sciences, one can find a wide range of different approaches working with Foucault's definition of discourse and his theoretical concepts. Apart from the original context in France, there is, since 2005, a broad discussion on socio-scientific discourse analysis in Germany. Here,
