Passage: From the beginning of her research in Nicaragua in 1986 until Nicaraguan Sign Language was well established, Kegl carefully avoided introducing the sign languages she knew, in particular American Sign Language, to the deaf community in Nicaragua. A type of linguistic imperialism had been occurring internationally for decades where individuals would introduce ASL to populations of deaf people in other countries, often supplanting existing local sign languages. Kegl's policy was to document and study rather than to impose or change the language or its community. While she did not interfere with deaf Nicaraguans gaining exposure to other sign languages, she did not introduce such opportunities. She has, however, documented contact and influences with other sign languages that began as early as the 1990s and that continue; critics, such as Felicia Ackerman, have taken issue with the ethics of isolating the Nicaraguan children.Kegl's organization Nicaraguan Sign Language Projects helped establish a deaf school staffed entirely by deaf Nicaraguan teachers and has supported deaf Nicaraguans in attending and presenting at international conferences.

Question: where did her research begin?
