    As the team describe in a paper posted (http://arxiv.org/abs/1605.04951) on arXiv, they found that figures did indeed matter-but not all in the same way. An average paper in PubMed Central has about one diagram for every three pages and gets 1.67 citations. Papers with more diagrams per page and, to a lesser extent, plots per page tended to be more influential (on average, a paper accrued two more citations for every extra diagram per page, and one more for every extra plot per page). By contrast, including photographs and equations seemed to decrease the chances of a paper being cited by others. That agrees with a study from 2012, whose authors counted (by hand) the number of mathematical expressions in over 600 biology papers and found that each additional equation per page reduced the number of citations a paper received by 22%. This does not mean that researchers should rush to include more diagrams in their next paper. Dr Howe has not shown what is behind the effect, which may merely be one of correlation, rather than causation. It could, for example, be that papers with lots of diagrams tend to be those that illustrate new concepts, and thus start a whole new field of inquiry. Such papers will certainly be cited a lot. On the other hand, the presence of equations really might reduce citations. Biologists (as are most of those who write and read the papers in PubMed Central) are notoriously mathsaverse. If that is the case, looking in a physics archive would probably produce a different result.

    Rez. in: JASIST 56(2005) no.11, S.1237-1238 (E. Yakel): "This book provides the profession with a cogent, thorough, and thoughtful introduction to digital reference. Janes not only provides the breadth of coverage expected in an introduction, but also depth into this important topic. Janes' approach is managerial or administrative, providing guidelines for reference work that can be applied in different settings. Janes creates a decision-making framework to help reference librarians make decisions concerning how, to what extent, and in what cases digital reference services will be delivered. In this way, Janes avoids dictating a "one-size-fits-all" model. This approach is the major strength of the book. Library administrators and heads of reference services will find the administrative approach welcome by helping them think through which digital reference policies and methods will best target core constituencies and their institutional environments. However, the book deserves a broader audience as professors will find that the book fits nicely in a general reference course. For all readers, the book is readable and engaging and also challenging and questioning. The book begins with a history of reference work, nicely positioning digital reference in this tradition and noting the changes wrought by the digital age. By doing this, the author establishes both continuity and change in reference work as well as the values surrounding this activity. These values are largely those from the library community and Support people's access to information as well as activities that support the use of information. Janes closes this chapter by noting that the continuing changes in demographics, technology, and connectivity will impact reference work in ways that are not yet imaginable. This introduction sets the tone for the rest of the book. Janes defines digital reference service as "the use of digital technologies and resources to provide direct, professional assistance to people who are seeking information, wherever and whenever they need it" (p. 29). This definition covers a lot of ground. Examples include everything from a public library answering email queries to commercial ask-an-expert services. While the primary audience is librarians, Janes continually reminds readers that many others perform reference activities an the World Wide Web. Furthermore, he cautions readers that there are larger forces shaping this activity in the world that need to acknowledged. In building a framework for decision-making, Janes outlines the types of digital reference service. This discussion covers the communieations modes, such as e-mail, chat, Web forms, etc. It also analyzes the modalities by which reference service is delivered: synchronous/ asynchronous. Using these two dimensions (communication method and synchronous/asynchronous), Janes presents the variety of contexts in which digital reference can take place and then outlines the strengths and weaknesses of each of these. This translates into a decision-making framework by which readers analyze their particular setting and then select the modes and modalities that world be most effective. This is a powerful device and demonstrates the many options (and perhaps also the obstacles) for providing digital reference service.

    Rez. in: KO 31(2004) no.2, S.117-118 (D. Campbell): "This excellent volume offers 22 papers delivered at an IFLA Satellite meeting in Dublin Ohio in 2001. The conference gathered together information and computer scientists to discuss an important and difficult question: in what specific ways can the accumulated skills, theories and traditions of librarianship be mobilized to face the challenges of providing subject access to information in present and future networked information environments? The papers which grapple with this question are organized in a surprisingly deft and coherent way. Many conferences and proceedings have unhappy sessions that contain a hodge-podge of papers that didn't quite fit any other categories. As befits a good classificationist, editor I.C. McIlwaine has kept this problem to a minimum. The papers are organized into eight sessions, which split into two broad categories. The first five sessions deal with subject domains, and the last three deal with subject access tools. The five sessions and thirteen papers that discuss access in different domains appear in order of in creasing intension. The first papers deal with access in multilingual environments, followed by papers an access across multiple vocabularies and across sectors, ending up with studies of domain-specific retrieval (primarily education). Some of the papers offer predictably strong work by scholars engaged in ongoing, long-term research. Gerard Riesthuis offers a clear analysis of the complexities of negotiating non-identical thesauri, particularly in cases where hierarchical structure varies across different languages. Hope Olson and Dennis Ward use Olson's familiar and welcome method of using provocative and unconventional theory to generate meliorative approaches to blas in general subject access schemes. Many papers, an the other hand, deal with specific ongoing projects: Renardus, The High Level Thesaurus Project, The Colorado Digitization Project and The Iter Bibliography for medieval and Renaissance material. Most of these papers display a similar structure: an explanation of the theory and purpose of the project, an account of problems encountered in the implementation, and a discussion of the results, both promising and disappointing, thus far. Of these papers, the account of the Multilanguage Access to Subjects Project in Europe (MACS) deserves special mention. In describing how the project is founded an the principle of the equality of languages, with each subject heading language maintained in its own database, and with no single language used as a pivot for the others, Elisabeth Freyre and Max Naudi offer a particularly vivid example of the way the ethics of librarianship translate into pragmatic contexts and concrete procedures. The three sessions and nine papers devoted to subject access tools split into two kinds: papers that discuss the use of theory and research to generate new tools for a networked environment, and those that discuss the transformation of traditional subject access tools in this environment. In the new tool development area, Mary Burke provides a promising example of the bidirectional approach that is so often necessary: in her case study of user-driven classification of photographs, she user personal construct theory to clarify the practice of classification, while at the same time using practice to test the theory. Carol Bean and Rebecca Green offer an intriguing combination of librarianship and computer science, importing frame representation technique from artificial intelligence to standardize syntagmatic relationships to enhance recall and precision.

    Footnote
    Chapter 2 (Technology and People) focuses an several theories of technological acceptance and diffusion. Unfortunately, Bruce's presentation is somewhat confusing as he moves from one theory to next, never quite connecting them into a logical sequence or coherent whole. Two theories are of particular interest to Bruce: the Theory of Diffusion of Innovations and the Theory of Planned Behavior. The Theory of Diffusion of Innovations is an "information-centric view of technology acceptance" in which technology adopters are placed in the information flows of society from which they learn about innovations and "drive innovation adoption decisions" (p. 20). The Theory of Planned Behavior maintains that the "performance of a behavior is a joint function of intentions and perceived behavioral control" (i.e., how muck control a person thinks they have) (pp. 22-23). Bruce combines these two theories to form the basis for the Technology Acceptance Model. This model posits that "an individual's acceptance of information technology is based an beliefs, attitudes, intentions, and behaviors" (p. 24). In all these theories and models echoes a recurring theme: "individual perceptions of the innovation or technology are critical" in terms of both its characteristics and its use (pp. 24-25). From these, in turn, Bruce derives a predictive theory of the role personal perceptions play in technology adoption: Personal Innovativeness of Information Technology Adoption (PIITA). Personal inventiveness is defined as "the willingness of an individual to try out any new information technology" (p. 26). In general, the PIITA theory predicts that information technology will be adopted by individuals that have a greater exposure to mass media, rely less an the evaluation of information technology by others, exhibit a greater ability to cope with uncertainty and take risks, and requires a less positive perception of an information technology prior to its adoption. Chapter 3 (A Focus an Usings) introduces the User-Centered Paradigm (UCP). The UCP is characteristic of the shift of emphasis from technology to users as the driving force behind technology and research agendas for Internet development [for a dissenting view, see Andrew Dillion's (2003) challenge to the utility of user-centerness for design guidance]. It entails the "broad acceptance of the user-oriented perspective across a range of disciplines and professional fields," such as business, education, cognitive engineering, and information science (p. 34).
