The purpose of this research study was to identify and define important components that might constitute an ecology of language (Mufwene 2001; Haugen 1972). Focusing on components as varied as social networks, physical ecology, identity and linguistic realities allowed for the construction of such a model, which was then applied to a specific case study addressing the vitality of Haitian Creole among first and second generation Haitian college students in South Florida. The resulting ecology of language model demonstrates that the competition and selection pressures guiding language use among first and second generation Haitian college students hinge on two ecological factors: the survey respondents' level of American acculturation and their desire to be involved in or affiliated with a separate subgroup of Haitians. The study found that (1) the reported language behavior of parents had no correlations with the respondents' interest in affiliating with other Haitians, and (2) Haitia n college students who do identify strongly with Haitian culture do not necessarily equate that cultural identity with the Haitian Creole language. These results suggest, in contrast to the claims of Zephir (2001), that Haitian college students will acculturate quickly into American linguistic society despite their desire to maintain the hyphenated identity of Haitian-American. Additionally, many of the conditions which are noted in the language endangerment literature (Grenoble & Whaley1998; Nettle & Romaine 2000; Crystal 2000) pointing towards language loss are occurring within the Haitian college community in South Florida. Despite the fact Haitian college students in South Florida all have positive attitudes towards Haitian culture and language, the respondents prefer to speak English rather than Haitian Creole. As is the case with other minority languages (Potowski 2010), it can be predicted that Haitian Creole will maintain its integrity and vitality in America continued / immigration. / by Kristyl Williams Kepley. / Thesis (Ph.D.)--Florida Atlantic University, 2011. / Includes bibliography. / Electronic reproduction.
