    Going Beyond Counting First Authors in Author Co-citation Analysis

    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

    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

    Dispelling the Myths Behind First-author Citation Counts

    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

    What Did Really Improve Our Mesoscale Hydrological Model? A Multidimensional Analysis Based on Real Observations

    No full text
    Modelers can improve a model by addressing the causes for the model errors (data errors and structural errors). This leads to implementing model enhancements (MEs), for example, meteorological data based on more monitoring stations, improved calibration data, and/or modifications in process formulations. However, deciding on which MEs to implement remains a matter of expert knowledge. After implementing multiple MEs, any improvement in model performance is not easily attributed, especially when considering different objectives or aspects of this improvement (e.g., better dynamics vs. reduced bias). We present an approach for comparing the effect of multiple MEs based on real observations and considering multiple objectives (MMEMO). A stepwise selection approach and structured plots help to address the multidimensionality of the problem. Tailored analyses allow a differentiated view on the effect of MEs and their interactions. MMEMO is applied to a case study employing the mesoscale hydro-sedimentological model WASA-SED for the Mediterranean-mountainous Isábena catchment, northeast Spain. The investigated seven MEs show diverse effects: some MEs (e.g., rainfall data) cause improvements for most objectives, while other MEs (e.g., land use data) only affect a few objectives or even decrease model performance. Interaction of MEs was observed for roughly half of the MEs, confirming the need to address them in the analysis. Calibration and increasing the temporal resolution showed by far stronger impact than any of the other MEs. The proposed framework can be adopted in other studies to analyze the effect of MEs and, thus, facilitate the identification and implementation of the most promising MEs for comparable cases

    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

    A estética da media art: as obras de Christa Sommerer e Laurent Mignonneau

    The theoretical trends and creation activities intended to somehow walk sideby- side with the discoveries and tecno-scientific developments. The contemporary scientific and technological thoughts wide and transform material basis and the aesthetics's production mode potentials. Such transformations can be observed in the Media Art field, an attributive manifestation to the contemporary context, which the main artistic investigations are focused on Computational Art, Tele-presence Art, Iimmersion, Virtual Reality, Transgenic Art and Genetic Art. Therefore, this master thesis has the objective to investigate the Aesthetic Theories which emerge from the Media Art context and have foundations on the idea of interactivity and interface, such as the Christa Sommerer's and Laurent Mignonneau's aesthetic results idealized based on the scientific, technological and artistics' thoughts. Broadly, the notion of the “Art as a live system” is adopted in order to comprehend the interative process as a set of chained elements, subject to constant intervection.CAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorAs tendências teóricas e atividades de criação procuraram de alguma forma caminhar lado a lado com as descobertas e os desenvolvimentos tecnocientíficos. Os pensamentos científicos e tecnológicos contemporâneos ampliam e transformam as bases materiais e os potenciais dos modos de produção estético. Tais transformações podem ser observadas no campo da Media Art, manifestação concernente ao contexto contemporâneo, cujas principais investigações artísticas centram-se na Arte Computacional, Arte da Telepresença, Imersão, Realidade Virtual, Arte Transgênica e Arte Genética. Portanto, a presente dissertação tem como objetivo pesquisar as Teorias Estéticas que emergem do contexto da Media Art fundamentadas na ideia de interatividade e interface, assim como os resultados estéticos de Christa Sommerer e Laurent Mignonneau construídos na interseção dos pensamentos científicos, tecnológicos e artísticos. Em linhas gerais, utiliza-se a noção de “Arte como sistema vivo” como recurso para compreender o processo interativo como um conjunto de elementos interconectados, sujeito à constante intervenção
