Transcribing sign communication used simultaneously with spoken English presents investigators with a unique problem: the singular quality of the bimodal communicative interactions cannot be accurately depicted using accepted conventions for recording either spoken or signed language samples. This article proposes guidelines for transcribing such data. The need for guidelines arose during an earlier study of the language development of a hearing child of deaf parents. To meet the immediate needs of that study, rules and conventions from previous studies were combined with newly generated ones, resulting in the guidelines proposed in this article. The guidelines can be applied to data in which intermodal linguistic influence is suspected. 相似文献

Human generated environmental problems are significant issues of global concern. Despite this, varying attitudes towards environments
continue to exist across the globe, impacting on environmental decision-making and action at local, national and international
levels. This paper probes some of the similarities and differences in environmental attitudes amongst pre-service teachers
in Australia, Republic of Maldives and Indonesia. Data were collected using an established environmental attitude questionnaire
and individual interviews. The three communities exhibited a similar range of environmental attitudes using the established
questionnaire but significant differences emerged when the interview data were analysed phenomenographically. These differences
reflect diversity within and across cultural groups that cannot be satisfactorily explained by the theory underpinning the
established questionnaire. Consequently, a revised conceptual framework is proposed. 相似文献

Digital documents in the networked information environment fundamentally change the ways that visual materials can be used in education and scholarly discourse. These new uses raise questions about research library strategies with regard to digitized visual materials as a part of their collections, challenge assumptions underlying intellectual property rights for images and their scope, and offer ways in which visual literacy can become a more integral part of the common educational experience. 相似文献
