    Going Beyond Counting First Authors in Author Co-citation Analysis

    Full text link
    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

    Variations on the Author

    “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 link
    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

    Reliability updating with inspection and monitoring data in deteriorating reinforced concrete slabs

    No full text
    Corrosion is a common phenomenon in engineering structures; examples include corrosion of the reinforcement in RC structures, corrosion of steel plates in ship hulls or localized corrosion in pipelines. These corrosion mechanisms are generally subject to random spatial variability, due to random changes in in-fluencing factors over space. When assessing the effect of inspections and measurements on the reliability of such structures, it is essential to account for this spatial variability: Due to correlation among influencing fac-tors at separate points, the measurement results obtained at one location contain information on the corrosion process at other locations. In this paper, a novel algorithm for reliability updating [Straub D. Probabilistic En-gineering Mechanics, 26(2): 254–258, 2011] is adopted to the spatial reliability analysis of RC corrosion con-ditional on measurements. The algorithm is computationally efficient and robust, thus facilitating the applica-tions to reliability updating of large-scale structural systems subject to corrosion. The method is applied to an example concrete slab subject to chloride induced corrosion of the reinforcement, for which spatial measure-ments of concrete cover depth and chloride profiles are available

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    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

    Business process modeling success: An empirically tested measurement model

    No full text
    The visualization of business processes in the form of process models has increased in popularity and importance. The resultant prevalence and magnitude of process modeling projects demand appropriate means of evaluating such initiatives. This paper presents a validated measurement model and instrument for assessing process modeling success. The final validated model employs 15 measures within the 3 dimensions - Model Quality, Process Impacts and Project Efficiency. The model was empirically tested with 290 responses to a global survey of process modelers. The overall study design consists of an exploratory model building phase (extensive literature review and multiple case studies) to identify salient success dimensions and measures, which was followed by an exploratory model testing phase. Test results evidence the discriminant validity of the model dimensions as well as their convergence on the single higher-order concept - Process modeling success (PM-Success). Criterion validity testing further evidences the additivity of the 3 dimensions of success, and the completeness of the resultant overarching second-order measure of PM-Success.\ud \ud The contributions from this work are twofold. From the perspective of practice, it offers a validated success model and measurement instrument that can be employed by organizations to measure the degree of success of completed process modeling projects. From an academic perspective: it presents a validated success measure, which can be used as the dependent variable in further research aimed at a better understanding of the important antecedents of process modeling success. Process modeling success can also be an important independent variable in research that aims to explore causal relations further along the Information Systems Development (ISD) cycle. In both research and practice, process modeling success benchmark scores can be valuable in comparative analyses across project types and project contexts, for highlighting process modeling related problems and issues deserving of attention, or best practices worthy of replication

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
