Abstract

This paper considers the need for a more systematic and critical approach to the academic study of information policy at national and international level. It reviews the complex, multifaceted nature of large-scale information policy problems and considers some of the main sources of confusion in the journal literature. It is argued that while information policy has been largey technology-driven, the consideration of information policy has, for historical reasons, typically been discipline-bounded. This has contributed to a fragmentation of research effort and a lack of consensus on the most appropriate home discipline for the study of information policy. In the search for a more critical scientific understanding of information policy issues, a brief review is made of the strenghts, limitations and applicability of the broad theoretical and methodological approaches which have been adopted, often implicitly, by writers reporting in the library and information science literature. The paper concludes with a consideration of some desirable characteristics for the design of information policy studies

Abstract

This paper provides a high-level overview of some of the main research themes and preoccupations that are reported in this special ciber issue of Aslib Proceedings: New Information Perspectives. The research activities of ciber are drawn together in the quest for a better understanding of the policy implications of large-scale knowledge production systems against the backdrop of profound technical change, uncertainty over business models, and new forms of consumer behaviour. The paper presents a series of conceptual frameworks that aim to contextualise ciber's work in bibliometrics, cybermetrics, research evaluation, scholarly communication, user studies, publishing strategies and policy analysis. The transparency that metrics can bring to the evaluation debate and the pivotal role of human information behaviour in determining those metrics, are discussed.

Abstract

Purpose - The purpose of this paper is to clarify earlier work on journal diffusion metrics. Classical journal indicators such as the Garfield impact factor do not measure the breadth of influence across the literature of a particular journal title. As a new approach to measuring research influence, the study complements these existing metrics with a series of formally described diffusion factors. Design/methodology/approach - Using a publication-citation matrix as an organising construct, the paper develops formal descriptions of two forms of diffusion metric: "relative diffusion factors" and "journal diffusion factors" in both their synchronous and diachronous forms. It also provides worked examples for selected library and information science and economics journals, plus a sample of health information papers to illustrate their construction and use. Findings - Diffusion factors capture different aspects of the citation reception process than existing bibliometric measures. The paper shows that diffusion factors can be applied at the whole journal level or for sets of articles and that they provide a richer evidence base for citation analyses than traditional measures alone. Research limitations/implications - The focus of this paper is on clarifying the concepts underlying diffusion factors and there is unlimited scope for further work to apply these metrics to much larger and more comprehensive data sets than has been attempted here. Practical implications - These new tools extend the range of tools available for bibliometric, and possibly webometric, analysis. Diffusion factors might find particular application in studies where the research questions focus on the dynamic aspects of innovation and knowledge transfer. Originality/value - This paper will be of interest to those with theoretical interests in informetric distributions as well as those interested in science policy and innovation studies.
