    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

    Socio-technical gaps and social capital formation in Online Collaborative Consumption communities

    No full text
    Information Communication Technologies (ICTs) are transforming social activities and interactions which are naturally varied and dynamic. In this process, ‘gaps’ develop between the technologies and emerging social requirements. Given that the main challenge for Computer Supported Cooperative Work (CSCW) is to identify and ameliorate these socio-technical gaps, it is essential to understand how individuals work and collaborate in groups, societies, and communities. The main question addressed in this study regards the identification of these gaps in the social activities of Online Collaborative Consumption (OCC). The intention is to improve user experience and design requirements to support OCC at the socio-technical design level. OCC facilitates sharing, swapping, trading, or renting products, services, and resources, via the computer-mediated interactions. Etsy, an online marketplace and community for handmade and craft goods, is the focus of this study as a community in which OCC takes place. The evaluation of online communities by using an ethnographic approach is an equally important question which this study investigates. Due to a lack of standard methods, a new combined methodological approach is proposed in this research (Predictive ethnography) and it was used in evaluation of collaborative communities to investigate the socio-technical gaps. In this approach, online ethnography complemented predictive evaluation with the aid of heuristics including sociability, usability, and user experience (UX) items. These heuristics were drawn from previous literature as the success factors for the online communities. The textual interactions from discussions of the forum and teams on Etsy that were related to these heuristics were collected and coded. Over 1000 posts from 178 threads were collected. Their frequencies were measured to demonstrate their importance, and further ethnography helped the researcher in qualitative analysis and meaning making of the textual interactions. The subsidiary question this research aims to answer is how social capital is developed in the OCC communities. Social capital is utilised as a tool to enhance the understanding of the socio-technical requirements of OCC communities and to improve the process of social capital generation. The same above-mentioned methodological approach (Predictive ethnography) was applied with the heuristics replaced by social capital measures. Over 9500 posts collected from 97 threads from the textual discussions of different Etsy teams. This study investigates the social capital formation in different types of teams such as topic-based ones that are created based on the common interest topics, and location-based ones that are created based on the shared locations of the members. In the topic-based teams, a significant amount of knowledge sharing and intellectual capital was observed. In location-based teams, most interactions were within social interactions and relational capital. The new method proposed in this research has shown its effectiveness in gaining insight from the natural discussions of the members. In total, 33 socio-technical gaps were identified and presented with possible recommendations. The most significant gaps concerned: Trust creation features; relevant rules of behaviour; clear displayed policies; and social presence tools

    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

    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

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    No full text
    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
