    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

    Home Literacy Environment and Reading Acquisition in Finland

    No full text
    This chapter reviews the findings of research on the associations between home literacy environment (HLE) and literacy development in Finland. Findings from longitudinal data including children transitioning from kindergarten to Grade 1 in the general population were examined. The findings of existing studies (1) support the premises of the home literacy model developed by Sénéchal and LeFevre [Child Development 73:445–460, 2002; Child Development 85:1552–1568, 2014], (2) shed light on the transactional processes between an HLE and children’s literacy development before and during grade school, (3) expand on the role of parental beliefs and child’s motivation within the home literacy model, and (4) provide evidence on the differential role of parent and child gender in HLE research. Practical implications of the findings are discussed.peerReviewe

    A home language and literacy environments theoretical model: evidence from systematic reviews of naturalistic variation across diverse contexts

    No full text
    A challenge to current theorizing on the home language and literacy environment (HLLE) is the naturalistic variability of homes globally. Our work draws on this variability to better understand the characteristics of home environments. Studies, including meta-analytic reviews, suggest significant, but weak, associations between the HLLE and child learning attainments. Relatedly, some distant factors like country-level wealth disparity moderate the association between the HLLE and child learning, but the home-school language mismatch, a more proximal factor, does not. Although studies do not explicate the underlying mechanisms or pathways by which homes and the wider ecosystems relate to child language and literacy skills, they help provide a nascent theorizing of how HLLEs may be conceptualized across diverse contexts. In this chapter, we describe our model showing both the micro- and macro-level factors that may account for the naturalistic variability across homes. We propose that such a multiple risk and protective factors model is ideal to direct future research priorities

    The interactions of home literacy and home numeracy environment in different countries and contexts

    No full text
    In this chapter, we explore the intersection between home literacy and home numeracy environments across contexts. First, we present empirically-based models of these two environments, exposing the literature imbalance which has focused predominantly on home literacy, and the complexities associated with the operationalization of these environments. Second, we compare findings about the relation between each of these environments and children’s developing literacy and mathematics skills. We highlight the need for more longitudinal studies to provide evidence for the persistent relations between the home learning environment and children’s academic achievement as well as the need for rigorous intervention studies to determine causal effects of these environments. Finally, we discuss the complex role of culture in shaping home literacy and numeracy environments, exploring global patterns of similarity and difference, and detailing the challenges of researching the home environments of diverse groups

    Dispelling the Myths Behind First-author Citation Counts

    Get PDF
    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
