Abstract

Purpose: This article outlines the development of extension as a discipline in Australia, its organization, and the ideological changes that have occurred from the second half of the nineteenth century through to the present.

Design/Methodology/Approach: It considers the evolution of extension across the different states of Australia from a national perspective and describes how the research development and extension (RD&E) complex has rotated through cycles of crises, highs, awakenings in thought and practice, and periods where achievements and institutions unravel.

Findings: Discussed is the tension between public and private sector extension, as well as the successes and failures of various paradigms. It considers the impacts of different agricultural policy on Australian agricultural RD&E across the decades. In particular it deals with the current ‘unravelling’ of the agricultural RD&E system in Australia, and tries to anticipate future demands on agricultural extension and how these services might be delivered into the future.

Practical Implications: The article challenges the reader to consider the discipline of extension as a subset of the greater society in which it exists. It provides an insight into how the agricultural research, development and extension capacity of a nation can be observed to ebb and flow over generations in accord with the rhythm of society.

Originality/Value: The article presents a perspective that has not been fully captured or understood until now.  相似文献

In the United States, research on child abuse and neglect is frequently criticized for being poorly performed and largely irrelevant to the important policy questions facing the field. Many of the problems plaguing research on child abuse and neglect are endemic to social science research generally, and this paper does not trod over such issues, which are well known and well described elsewhere. Instead, this paper describes how the inadequacy of definitions of “child abuse” and “child neglect” used by research studies places an additional—and largely unnoticed—burden on research, which aggravates the impact of these more general problems. Existing definitions of “child abuse” and “child neglect” fail to meet research needs because they lack: (1) comparability, (2) reliability, and (3) taxonomic delineation. As a result, they compromise the findings of incidence studies, sequelae studies, etiological studies, and program effectiveness studies. Therefore, if real progress is to be made in understanding child abuse and neglect, definitional issues must become an explicit methodological concern. Specifically, future research should include: (I) a careful determination of definitional needs, (2) the development of operational definitions to meet those needs, and (3) the circumspect statement of findings based on the limitations imposed by such definitions.  相似文献
