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

In recent years university presses have undergone some significant changes, such as expansion of their scope to include materials
that may have appeal beyond the scholarly market. This article investigates, through the use of a survey of university libraries,
the acquisition of university press products by libraries. In general, recent years have been changes in the relationship
between university presses and libraries that have resulted in fewer items being purchased by the libraries. 相似文献

Three factors tied with secondary student success in content‐area reading are demonstrated: (a) validated teacher‐focused and student‐focused interventions, (b) integrated and comprehensive service delivery systems, and (c) well‐designed, data‐based professional developmental programs. Difficult challenges face secondary students with LD and their teachers with regard to these students’ participation and success in required general education classes. Recently, instructional methods and materials have been developed and validated for promoting these students’ success. Some of them focus on how general education teachers plan and teach their content‐area courses; others focus on giving students the strategies they need to respond independently to the demands of their courses. This article describes these instructional methods, a service‐delivery model for implementing these interventions in secondary schools, and professional‐development mechanisms and administrative support that must be in place for the model to be maintained effectively. 相似文献

A small nation in the middle of the North Atlantic, Iceland currently has a population of 265,000 (1996). The Iceland language has changed very little since the island was settled some 11 centuries ago. Despite the relatively small number of people who speak the language and irrespective of the globalisation efforts by the international community, which includes the ever-increasing influence of English worldwide, the Icelandic language and culture are stronger than ever. The current volume and variety of publications of Icelandic works in all areas have never been as great. Icelandic is a living and growing language. Growth in vocabulary, in response to recent phenomena like the introduction of new technology, has primarily come about with the development of new words from the language's roots. The near absence of Latin, Greek and, more recently, English or Danish words in Icelandic, is striking. Iceland's language policy is not only a governmental policy. It is a policy that comes from the grassroots with the government and official institutions viewing their job as one of service to the people of Iceland. Icelanders are very proud of their language and are extremely determined to continually develop and preserve it for future generations. 相似文献
