    Going Beyond Counting First Authors in Author Co-citation Analysis

    No full text
    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Dispelling the Myths Behind First-author Citation Counts

    No full text
    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods

    The intrinsic B-mode polarisation of the cosmic microwave background

    Abstract. We estimate the B-polarisation induced in the Cosmic Microwave Background by the non-linear evolution of density perturbations. Using the second-order Boltzmann code SONG, our analysis incorporates, for the first time, all physical effects at recombination. We also include novel contributions from the redshift part of the Boltzmann equation and from the bolometric definition of the temperature in the presence of polarisation. The remaining line-of-sight terms (lensing and time-delay) have previously been studied and must be calculated non-perturbatively. The intrinsic B-mode polarisation is present independent of the initial conditions and might contaminate the signal from primordial gravitational waves. We find this contamination to be comparable to a primordial tensor-to-scalar ratio of r ' 10−7 at the angular scale ` ' 100, where the primordial signal peaks, and r ' 5 × 10−5 at ` ' 700, where the intrinsic signal peaks. Therefore, we conclude that the intrinsic B-polarisation from second-order effects is not likely to contaminate future searches of primordial gravitational waves.ar X i

    Pragmatic Case Studies as a Source of Unity in Applied Psychology

    No full text
    To unify or not to unify applied psychology: that is the question. In this article we review pendulum swings in the historical efforts to answer this question—from a comprehensive, positivist, “top-down,” deductive yes between the 1930s and the early 60s, to a postmodern no since then. A rationale and proposal for a limited, “bottom-up,” inductive yes in applied psychology is then presented, employing a case-based paradigm that integrates both positivist and postmodern themes and components. This paradigm is labeled “pragmatic psychology” and, its specific use of case studies, the “Pragmatic Case Study Method” (“PCS Method”). We call for the creation of peer-reviewed journal-databases of pragmatic case studies as a foundational source of unifying applied knowledge in our discipline. As one example, the potential of the PCS Method for unifying different angles of theoretical regard is illustrated in an area of applied psychology, psychotherapy, via the case of Mrs. B. The article then turns to the broader historical and epistemological arguments for the unifying nature of the PCS Method in both applied and basic psychology.Peer reviewe

    The Role of Epistemic Communities in the Global Response to Severe Acute Respiratory Syndrome: Implications for Global Health Governance

    No full text
    The aim of this thesis was to understand the role of epistemic communities in the global response to Severe Acute Respiratory Syndrome (SARS), through the theoretical lens of Social Constructivism, in order to explain the extent to which ideational factors and normative power constructed through them contributed to the shaping of Global Health Governance (GHG) surrounding infectious disease outbreaks. The methodology of this thesis combined key informants interviews with archival document‐based research. Archival research consisted of gathering and reviewing government documents, publications of intergovernmental organizations, media reports, press briefings, and policy papers. Discourse analysis was employed to systematically examine the wide range of data gathered. The thesis explored how different discourses have driven the changes in public health reasoning and practice, in the form of prioritisation of certain actions in the global response to SARS at various points in time. In order to show the ideational shifts over time, the SARS story was divided into three key phases in terms of the progress of the outbreak. This thesis finds that the global response to the SARS outbreak over three phases was shaped by contestation among various discourses, which framed the perceived priority issues and policy responses pursued. These ideas did not simply arise as governing norms, but ideational success occurred as a result of collective advancement by actors who were coalesced around particular policy ideas. The thesis provided an account of the interplay between policy ideas and key actors, in the form of epistemic communities, and how epistemic communities served as key sources of advice to policy making during the SARS outbreak. The thesis demonstrates that in many ways, the GHG of SARS mirrored, the GHG of other global health issues in terms of framing of issues and the actors in the formation of and justification for interests in global health. By illustrating the origins and significance of the multiplicity of ideas shaping collective action on SARS, this thesis underscores that governance response in terms of policy outcomes is the product of reconciling health with a plethora of competing priorities, and political economic goals via social construction of reality. The thesis considered the implications of the findings for conceptual understanding of GHG of infectious diseases, and for strengthening policies and practices to address the global infectious disease outbreaks

    Appropriate Similarity Measures for Author Cocitation Analysis

    No full text
    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
