Scaling Analysis of Author Level Bibliometric Indicators
Full text linkDespite of the concerns from the bibliometric community, evaluation of the individual through bibliometric indices is already performed as a form of ‘pseudo peer review’ in selection of candidates for tenure, in background checks of potential employees’ publicationand citation impact, and in appraisal of funding applications. As part of developing the ACUMEN portfolio we therefore undertook an extensive review of 114 bibliometric indicators in Wildgaard, Schneider and Larsen (2014) to identify 1) which author level indices are useful to document the effect of publication performance, 2) identify which scientific activities it is possible to measure and with which indices, 3) analyse the applicability of these indices by discussing the strengths and weakness of each one, and 4) identify if there is a need for any additional novel indicators to measures the performance of individuals. The review confirmed that there is no immediate need to develop new bibliometric indicators. There is a wealth of indicators to choose from, some used in practice and some theoretical only. There is however a need to understand the usefulness of existing indicators and which ones represent independent research activities of authors. We have begun our investigation into how indicators complement each other, specifically if there is a redundancy among indicators, i.e. two or more indicators measure the same thing, and which indicators are the “best” choice in regards to four predefined disciplines. The main parameter we judge the usefulness of indicators is on their simplicity, understood as the simplicity of data collection and the simplicity of mathematical computation for each indicator (Wildgaard, Schneider & Larsen 2014). The present study is a further investigation into which effects of publishing and citing these simple indicators attempt to capture
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Paving the way for a new composite indicator on business model innovations
No full textThe paper conceptualises business model innovations (BMI) as a fundamental change of the mechanisms and arrangements of how a company creates, delivers and captures value. It translates this definition into a composite innovation indicator that consists of a combination of radical product and radical process innovations, or radical product innovations combined with marketing and organisational innovations. Implementing this definition with empirical data from the Community Innovation Surveys (CIS) in Europe, we find that roughly one out of 20 SMEs has introduced a BMI in the three-year period preceding the surveys.http://sti2014.cwts.nl/download/f-y2w2.pd
Uso de mapas da ciência no contexto de políticas científicas
No full textThis paper discuss the complex relations adopted by Semiology and media theory, to propose a televisual communication oriented semiotics, capable to embrace the specificities of this kind of media process. Thus, after to point the inadequacy of the elements enforcement of a immanent Semiology, or apllied to cinema, to the television analysis, it endorses the notion of gender promise as a replacement to the notion of contract or pact, as subjacent to the media communication.This paper discuss the complex relations adopted by Semiology and media theory, to propose a televisual communication oriented semiotics, capable to embrace the specificities of this kind of media process.

Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
Unwrapping “impact” for evaluation : A co-word analysis of the UK REF2014 policy documents using VOSviewer
No full textAssessment of expertise overlap between an expert panel and research groups
Full text linkDiscipline-specific research evaluation exercises are typically carried out by committees of peers, expert panels. Currently, there are no available methods that can measure overlap in expertise between a panel and the units of assessment. This research in progress paper explores a bibliometric approach to determining the overlap of expertise, using the 2010 research evaluation of nine physics research groups of the University of Antwerp as a test case. Overlay maps were applied to visualize to what extent the groups and panel members publish in different Web of Science subject categories. There seems to be a moderate disparity between the panel’s and the groups’ expertise. The panel was not as diverse as the groups that needed to be assessed. Future research will focus on journal level overlay maps, similarity testing, and a comparison with other disciplines
