Thông tin về tạp chí
The journal publishes research papers with novel methods or results of wide significance, in all the information-related disciplines. Critical and scholarly reviews are welcome, as are reviews of the evidence base for professional practice, and shorter speculative articles. We particularly welcome submissions exploring topics where concepts and models in the library and information sciences overlap with those in cognate disciplines: these disciplines include, but are not limited to, psychology and cognitive science, the physical sciences, communication and media studies, museum studies, computer science, sociology and publishing. JDoc provides a link between research, scholarship and reflective professional practice. We also welcome contributions in the 'Speculation in Documentation' category.

THE AMBIGUITY OF BRADFORD'S LAW Recent discussion of Bradford's law of scatter has been founded on two formulations that are not mathematically equivalent. A method of comparing the two formulations against empirical data is developed, and the results using four sets of existing data are discussed. The results show that one particular formulation is more consistent with the practical situation.

Discourse structure differences in lay and professional health communication Purpose In this paper the authors seek to compare lay (consumer) and professional (physician) discourse structures in answers to diabetes‐related questions in a public consumer health information website. Design/methodology/approach Ten consumer and ten physician question threads were aligned. They generated 26 consumer and ten physician answers, constituting a total dataset of 717 discourse units (in sentences or sentence fragments). The authors depart from previous LIS health information behaviour research by utilizing a computational linguistics‐based theoretical framework of rhetorical structure theory, which enables research at the pragmatics level of linguistics in terms of the goals and effects of human communication. Findings The authors reveal differences in discourse organization by identifying prevalent rhetorical relations in each type of discourse. Consumer answers included predominately (66 per cent) presentational rhetorical structure relations, those intended to motivate or otherwise help a user do something (e.g. motivation, concession, and enablement). Physician answers included mainly subject matter relations (64 per cent), intended to inform, or simply transfer information to a user (e.g. elaboration, condition, and interpretation). Research limitations/implications The findings suggest different communicative goals expressed in lay and professional health information sharing. Consumers appear to be more motivating, or activating, and more polite (linguistically) than physicians in how they share information with consumers online in similar topics in diabetes management. The authors consider whether one source of information encourages adherence to healthy behaviour more effectively than another. Originality/value Analysing discourse structure – using rhetorical structure theory – is a novel and promising approach in information behaviour research, and one that traverses the lexico‐semantic level of linguistic analysis towards pragmatics of language use.

Experimental components for the evaluation of interactive information retrieval systems This paper presents a set of basic components which constitutes the experimental setting intended for the evaluation of interactive information retrieval (IIR) systems, the aim of which is to facilitate evaluation of IIR systems in a way which is as close as possible to realistic IR processes. The experimental setting consists of three components: (1) the involvement of potential users as test persons; (2) the application of dynamic and individual information needs; and (3) the use of multidimensional and dynamic relevance judgements. Hidden under the information need component is the essential central sub‐component, the simulated work task situation, the tool that triggers the (simulated) dynamic information needs. This paper also reports on the empirical findings of the metaevaluation of the application of this sub‐component, the purpose of which is to discover whether the application of simulated work task situations to future evaluation of IIR systems can be recommended. Investigations are carried out to determine whether any search behavioural differences exist between test persons‘ treatment of their own real information needs versus simulated information needs. The hypothesis is that if no difference exists one can correctly substitute real information needs with simulated information needs through the application of simulated work task situations. The empirical results of the meta‐evaluation provide positive evidence for the application of simulated work task situations to the evaluation of IIR systems. The results also indicate that tailoring work task situations to the group of test persons is important in motivating them. Furthermore, the results of the evaluation show that different versions of semantic openness of the simulated situations make no difference to the test persons’ search treatment.

SCIENTISTS AND INFORMATION: II. PERSONAL FACTORS IN INFORMATION BEHAVIOUR The Kirton Adaption‐Innovation Inventory and the Learning Styles Questionnaire were used as part of a wider investigation, reported in an earlier paper, to explore the influence of personality, discipline and organisational structure on the information behaviour of biochemists, entomologists and statisticians working at an agricultural research station (n = 67). Results from the psychometric tests were assessed in terms of the groups obtained from a cluster analysis. Groups identified by the KAI as Innovators and by the LSQ as Activists sought information more widely, more enthusiastically and from more diverse sources than other groups. Groups identified as Adaptors by the KAI and Reflectors by the LSQ, were more controlled, methodical and systematic in their information behaviour.

Exploring a framework for comprehensive and successful preservation management in libraries Purpose This paper aims to explore a theoretical and methodological approach to preservation management in libraries, relying on the basic presumption that preservation is a complex and comprehensive process that involves many different and seemingly diverse aspects whose efficiency lies in preservation management. Design/methodology approach Using a case study of Croatia, the paper describes a methodology for exploring the general preservation management context and presents a preservation management model that comprises five key components. Findings The paper offers insight into preservation management issues in a specific national context. Research limitations/implications Although this paper focuses primarily on written heritage in libraries, it is applicable to other types of heritage and to other types of information institutions. Practical implications The theoretical and methodological approach presented in this paper and described in the example of Croatia can be useful for exploring similar issues in other countries. It can be expanded to other types and forms of heritage and heritage institutions. Originality/value The paper describes a model of organising preservation activities into an efficient and successful preservation system, and establishes a methodology for exploring diverse preservation issues on national and institutional levels.

Concept theory and semiotics in knowledge organization Purpose The purpose of this paper is to explore the basics of semiotic analysis and concept theory that represent two dominant approaches to knowledge representation, and explore how these approaches are fruitful for knowledge organization. Design/methodology/approach In particular the semiotic theory formulated by the American philosopher C.S. Peirce and the concept theory formulated by Ingetraut Dahlberg are investigated. The paper compares the differences and similarities between these two theories of knowledge representation. Findings The semiotic model is a general and unrestricted model of signs and Dahlberg's model is thought from the perspective and demand of better knowledge organization system (KOS) development. It is found that Dahlberg's concept model provides a detailed method for analyzing and representing concepts in a KOS, where semiotics provides the philosophical context for representation. Originality/value This paper is the first to combine theories of knowledge representation, semiotic and concept theory, within the context of knowledge organization.
