Although sometimes considered to be only marginally related to the key academic goals of establishing claims and reputations, acknowledgments are commonplace in scholarly communication and virtually obligatory in dissertation writing. The significance of this disregarded "Cinderella" genre lies partly in the opportunities it offers students to present a social and scholarly self disentangled from academic discourse conventions and personally thank those who have shaped the accompanying text. Beyond the role it plays in academic gift giving and self-presentation, however, the textualization of gratitude reveals social and cultural characteristics, an intimation of disciplinary specialization within a broad generic structure. This analysis of the acknowledgments accompanying 240 Ph.D. and M.A. dissertations written by nonnative speakers of English suggests that personal gratitude is mediated by disciplinary preferences and strategic career choices, reflecting one way in which postgraduate writing represents a situated activity.
