    Abstract
    The article reports the findings of a content analysis study of 16 student-group proposals for a grade eight history project. The students listed their topic and thesis in the proposal, and information in support of their thesis. The study's focus is this topic-to-thesis transition. The study's conceptual framework is Kuhlthau's six stage ISP Model's transition from exploring information in Stage 3 to formulating a focus or personal perspective on the assignment topic in Stage 4. Our study coding scheme identifies elements of the students' implicit knowledge in the 16 proposals. To validate implicit knowledge as a predictor of successful student performance, implicit knowledge was coded, scored, and then the correlation coefficient was established between the score and the students' instructors' marks. In Part 2 of the study we found strong and significant association between the McGill coding scores and the instructors' marks for the 16 proposals. This study is a first step in identifying, operationalizing, and testing user-centered implicit knowledge elements for future implementation in interactive information systems designed for middle school students researching a thesis-objective history assignment.

    Abstract
    The aim of this study was to measure the efficiency of the system by which scientists worldwide communicate results to each other, providing one measure of the degree to which the system, including all media, functions well. A randomly selected and representative sample of 246 active research scientists worldwide was surveyed. The main measure was the reported rate of "late finds": scientific literature that would have been useful to scientists' projects if it had been found at the beginning of these projects. The main result was that 46% of the sample reported late finds (±6.25%, p0.05). Among respondents from European Union countries or other countries classified as "high income" by the World Bank, 42% reported late finds. Among respondents from low- and middle-income countries, 56% reported late finds. The 42% rate in high-income countries in 2009 can be compared with results of earlier surveys by Martyn (1964a, b, 1987). These earlier surveys found a rate of 22% late finds in 1963-1964 and a rate of 27% in 1985-1986. Respondents were also queried about search habits, but this study failed to support any explanations for this increase in the rate of late finds. This study also permits a crude estimate of the cost in time and money of the increase in late finds.

    Abstract
    The present essay is based on research funded by the German Ministry of Economics and Technology and carried out by the Munich School of Philosophy (Prof. Godehard Brüntrup) in cooperation with the IT company Comelio GmbH. It is concerned with setting up the philosophical framework for a systematic, hierarchical and categorical account of questions and answers in order to use this framework as an ontology for software engineers who create a tool for intelligent questionnaire design. In recent years, there has been considerable interest in programming software that enables users to create and carry out their own surveys. Considering the, to say the least, vast amount of areas of applications these software tools try to cover, it is surprising that most of the existing tools lack a systematic approach to what questions and answers really are and in what kind of systematic hierarchical relations different types of questions stand to each other. The theoretical background to this essay is inspired Barry Smith's theory of regional ontologies. The notion of ontology used in this essay can be defined by the following characteristics: (1) The basic notions of the ontology should be defined in a manner that excludes equivocations of any kind. They should also be presented in a way that allows for an easy translation into a semi-formal language, in order to secure easy applicability for software engineers. (2) The hierarchical structure of the ontology should be that of an arbor porphyriana.

    Abstract
    In the context of online question-answering services, an intermediary clarifies the user's needs by eliciting additional information. This research proposes that these elicitations will depend on the type of question. In particular, this research explores the relationship between three constructs: question types, elicitations, and the fee that is paid for the answer. These relationships are explored for a few different question typologies, including a new kind of question type that we call Identity. It is found that the kinds of clarifications that intermediaries elicit depend on the type of question in systematic ways. A practical implication is that interactive question-answering services-whether human or automated-can be steered to focus attention on the kinds of clarification that are evidently most needed for that question type. Further, it is found that certain question types, as well as the number of elicitations, are associated with higher fees. This means that it may be possible to define a pricing structure for question-answering services based on objective and predictable characteristics of the question, which would help to establish a rational market for this type of information service. The newly introduced Identity question type was found to be especially reliable in predicting elicitations and fees.

    Abstract
    Keeping up to date with research developments is a central activity of academic researchers, but researchers face difficulties in managing the rapid growth of available scientific information. This study examined how researchers stay up to date, using the information journey model as a framework for analysis and investigating which dimensions influence information behaviors. We designed a 2-round study involving semistructured interviews and prototype testing with 61 researchers with 3 levels of seniority (PhD student to professor). Data were analyzed following a semistructured qualitative approach. Five key dimensions that influence information behaviors were identified: level of seniority, information sources, state of the project, level of familiarity, and how well defined the relevant community is. These dimensions are interrelated and their values determine the flow of the information journey. Across all levels of professional expertise, researchers used similar hard (formal) sources to access content, while soft (interpersonal) sources were used to filter information. An important "pain point" that future information tools should address is helping researchers filter information at the point of need.

    Abstract
    Purpose - Uncovering faculty members' conceptions of Information Literacy (IL), as well as exploring their perceptions with regard to the importance given to a previously defined set of core IL competences grouped into four categories: searching, evaluation, processing and communication and dissemination. Ascertaining the possible differences among the five knowledge branches (arts and humanities, sciences, social and legal sciences, health sciences, and technical disciplines); and understanding the importance granted to a set of learning improvement initiatives by the faculty. The paper aims to discuss these issues. Design/methodology/approach - The survey was completed by a set of faculty members from the University of Granada (Spain). Data were collected using the IL-HUMASS survey. The research is based on subjective data, first approached from a descriptive point of view. Later, data correlation, analysis and non-parametric tests were used with the goal of finding significant differences of faculty perceptions among the relevant academic areas. Findings - Results suggest that more than half of the surveyed faculty have what the authors define as an Academic Concept of IL. The IL categories of communica\tion and dissemination and searching were graded in significance by the staff as being "very important," while those of evaluation and processing were assigned a slightly lesser rating of "important." Results suggest that IL awareness falls into two broad groups differentiated by subject discipline: those from health sciences, social and legal sciences and arts and humanities representing the first group, and sciences and technical disciplines the other. Research limitations/implications - This approach address the subjective status of faculty concepts in a single university, but also in all knowledge branches. Future research is needed. Originality/value - This is one of the few papers regarding faculty perceptions of IL.

    Abstract
    Purpose - This research seeks to gain a detailed understanding of how researchers come across information serendipitously, grounded in real-world examples. This research was undertaken to enrich the theoretical understanding of this slippery phenomenon. Design/methodology/approach - Semi-structured critical incident interviews were conducted with 28 interdisciplinary researchers. Interviewees were asked to discuss memorable examples of coming across information serendipitously from their research or everyday life. The data collection and analysis process followed many of the core principles of grounded theory methodology. Findings - The examples provided were varied, but shared common elements (they involved a mix of unexpectedness and insight and led to a valuable, unanticipated outcome). These elements form part of an empirically grounded process model of serendipity. In this model, a new connection is made that involves a mix of unexpectedness and insight and has the potential to lead to a valuable outcome. Projections are made on the potential value of the outcome and actions are taken to exploit the connection, leading to an (unanticipated) valuable outcome. Originality/value - The model provides researchers across disciplines with a structured means of understanding and describing serendipitous experiences.

    Abstract
    This article describes an approach based on structuration theory (Giddens, 1979, 1984; Orlikowski, 1992, 2000) and communities of practice (Wenger, 1998) that can be used to guide investigation into the dynamics of online question and answer (Q&A) communities. This approach is useful because most research on Q&A sites has focused attention on information retrieval, information-seeking behavior, and information intermediation and has assumed uncritically that the online Q&A community plays an important role in these domains of study. Assuming instead that research on online communities should take into account social, technical, and contextual factors (Kling, Rosenbaum, & Sawyer, 2005), the utility of this approach is demonstrated with an analysis of three online Q&A communities seen as communities of practice. This article makes a theoretical contribution to the study of online Q&A communities and, more generally, to the domain of social reference.

    Abstract
    This study presents and tests a research model of the outcomes of information literacy instruction (ILI) given to undergraduate business students. This model is based on expectation disconfirmation theory and insights garnered from a recent qualitative investigation of student learning outcomes from ILI given at three business schools. The model was tested through a web survey administered to 372 students. The model represents psychological, behavioral, and benefit outcomes as second-order molecular constructs. Results from a partial least squares (PLS) analysis reveal that expectation disconfirmation influences perceived quality and student satisfaction. These in turn affect student psychological outcomes. Further, psychological outcomes influence student behaviors, which in turn affect benefit outcomes. Based on the study's findings, several recommendations are made.

    Abstract
    Purpose Information seeking for child-rearing is an increasingly popular topic in the medical and social science literature, though a theoretical framework in which to understand this phenomenon is still missing. The paper aims to discuss this issue. Design/methodology/approach The authors present results from a qualitative research in which data were obtained from 21 interviews and the personal experience of one of the authors. Participants were all mothers supportive of attachment parenting, a parenting style inspired by attachment theory which advocates making parenting decisions on a strong basis of information. They Findings Results were analyzed using grounded theory and allowed to define five major themes: becoming a mother implies a new perception of oneself in which it is common to feel more in need for information; the need to search for information originates in situations of "conflict" or crisis, or as a consequence of conflicting information; information is judged and weighed on the basis of affect and perceptions; scientific and experiential knowledge are valued as complementary; and finally, information seeking appears as one activity of identity work. Originality/value Placing conflict, instead of uncertainty, at the beginning of the search process allows to emphasize the role of information seeking in mediating relationships and interactions at a societal level. From this point of view, the authors understand that LIS should pay more attention to information seeking as an important factor in social change.

    Abstract
    Purpose - The purpose of this paper is to present a snapshot of virtual reference services (the use of instant messaging or chat for enquiries) in UK academic libraries, and provide information about software for libraries considering providing a virtual reference service. Design/methodology/approach - The paper summarises the results of a 2008 UK-wide survey of academic libraries and gives a brief overview and comparison matrix of top virtual reference software products as tested by the Virtual Enquiry Project. Findings - Virtual reference services are not widespread in UK academic libraries. However, current service providers are planning to continue or expand services and a majority of academic libraries surveyed are considering starting a service. Originality/value - This is the first survey of its kind among UK academic libraries.

    Abstract
    This article presents a user study showing the effectiveness of a linked-based, virtual integration infrastructure that gives users access to relevant online resources, empowering them to design an information-seeking path that is specifically relevant to their context. IntegraL provides a lightweight approach to improve and augment search functionality by dynamically generating context-focused "anchors" for recognized elements of interest generated by library services. This article includes a description of how IntegraL's design supports users' information-seeking behavior. A full user study with both objective and subjective measures of IntegraL and hypothesis testing regarding IntegraL's effectiveness of the user's information-seeking experience are described along with data analysis, implications arising from this kind of virtual integration, and possible future directions.

    Abstract
    Purpose - The purpose of this paper is to examine whether there is a need to consider gender or sex differences as variables in information behaviour research and, if so, how? Design/methodology/approach - A metasynthesis approach is used. A preliminary framework to categorise information behaviour research on women is developed by integrating main themes from feminist research and information behaviour research. Within each category, studies are compared and contrasted, to identify similar and divergent themes. Themes are then compared across categories, to synthesise the main concepts. Findings - The categorisation works for most studies, apart from a group of studies on health information use, communicating risk and decision making. The meta-synthesis indicates the importance of concepts such as situation (as mesh), intermediaries (as node with connections), and connecting behaviour. Gender-related or, rather gender-ascribed, constructs, such as concern for others, not gender alone are likely to be important variables in information behaviour. Research limitations/implications - The meta-synthesis is a top-level synthesis, as the number of studies prohibited a more detailed approach. Further meta-synthesis of a few high quality research studies would help to confirm the findings. Practical implications - The synthesis illuminates a different perspective on information behaviour: the network of information users rather than the individual information seeker. Originality/value - The synthesis integrates some feminist research themes with information behaviour research, and the findings have implications for general information behaviour research.

    Abstract
    Purpose - In "Coming across information serendipitously - Part 1: a process model" the authors identified common elements of researchers' experiences of "coming across information serendipitously". These experiences involve a mix of unexpectedness and insight and lead to a valuable, unanticipated outcome. In this article, the authors aim to show how the elements of unexpectedness, insight and value form a framework for subjectively classifying whether a particular experience might be considered serendipitous and, if so, just how serendipitous. Design/methodology/approach - The classification framework was constructed by analysing 46 experiences of coming across information serendipitously provided by 28 interdisciplinary researchers during critical incident interviews. "Serendipity stories" were written to summarise each experience and to facilitate their comparison. The common elements of unexpectedness, insight and value were identified in almost all the experiences. Findings - The presence of different mixes of unexpectedness, insight and value in the interviewees' experiences define a multi-dimensional conceptual space (which the authors call the "serendipity space"). In this space, different "strengths" of serendipity exist. The classification framework can be used to reason about whether an experience falls within the serendipity space and, if so, how "pure" or "dilute" it is. Originality/value - The framework provides researchers from various disciplines with a structured means of reasoning about and classifying potentially serendipitous experiences.

    Abstract
    Design/methodology/approach An operationalisation of the model is presented based on the theory of expectancy-value and on the operationalisation used when the model was first developed. Data for the analysis were collected from a sample of seven informants working as consultants in Danish municipalities. Each participant filled out a questionnaire, kept a log book for a week and participated in a subsequent interview to elicit data regarding their information source behaviour and task motivation. Findings Motivation affected source use when the informants search for information as part of their professional life. This meant that the number of sources used and the preference for interpersonal and internal sources increased when the task had high-value motivation or low-expectancy motivation or both. Research limitations/implications The study is based on a relatively small sample and considers only one motivation theory. This should be addressed in future research along with a broadening of the studied group to involve other professions than municipality consultants. Originality/value Motivational theories from the field of psychology have been used sparsely in studies of information seeking. This study operationalises and verifies such a theory based on a theoretical adaptation of this model made by Savolainen (2012c).

    Abstract
    Purpose The current understanding of serendipity is based primarily on studies employing westerners as the participants, and it remains uncertain whether or not this understanding would be pervasive under different cultures, such as in China. In addition, there is not a sufficient systematic investigation of context during the occurrence of serendipity in current studies. The purpose of this paper is to examine the above issues by conducting a follow-up empirical study with a group of Chinese scholars. Design/methodology/approach The social media application "WeChat" was employed as a research tool. A diary-based study was conducted and 16 participants were required to send to the researchers any cases of serendipity they encountered during a period of two weeks, and this was followed by a post-interview. Findings Chinese scholars experienced serendipity in line with the three main processes of: encountering unexpectedness, connection-making and recognising the value. An updated context-based serendipity model was constructed, where the role of context during each episode of experiencing serendipity was identified, including the external context (e.g. time, location and status), the social context and the internal context (e.g. precipitating conditions, sagacity/perceptiveness and emotion). Originality/value The updated context model provides a further understanding of the role played by context during the different processes of serendipity. The framework for experiencing serendipity has been expanded, and this may be used to classify the categories of serendipity.
