The role of the literary agent and the reception granted agents by publishers have changed markedly over the course of the twentieth century. Henry Holt’s views of agents, written in the first decade of the century, help define the status and activities of agents at that time. These are compared with the role of agents today, using archival sources, the book trade literature, and interviews. Thomas L. Bonn, review editor of this journal, is a librarian, Library at State University College at Cortland. He is the author ofUnder Cover: An Illustrated History of American Mass Market Paperbacks andHeavy Traffic and High Culture: The New American Library as Literary Gatekeeper. He is working on a study of American literary agents.  相似文献

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
