    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

    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

    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

    Bezpieczeństwo polityczne w systemach autorytarnych z gospodarką opartą na rencie surowcowej: wynik „umowy społecznej” i wysokich cen surowców?

    Full text link
    Most researchers believe that states which are rich in natural resources are more able to main- tain political stability in comparison to countries without such an access to exceptional profits. However, some rent resource autocracies are unanimously considered fragile, and their ability to extract maximum rents does not always contribute to political and economic security during price fluctuations. Based on the idea that the state’s ability to extract resources imposes on it certain ob- ligations, the research question touches upon the quality of governance as a supposed core factor, which mediates the resource dependence and political security in terms of stateness and the ability to fulfil the “social contract.” The latter is described as implementation of political decisions, pro- vision of public goods and services. However, the quality of governance is substantially different in various autocratic systems. Using case-study and descriptive statistics, the authors try to reveal the context and ascertain which factors trigger the horizon length of autocrats` political strategies during rising and falling resource prices. The authors affirm that resource dependence negatively affects political security less due to an absence of economic growth during price breaks, and more due to the struggle of political elites for the redistribution of resources, absence of disciplinary mechanisms, weak representation and accountability systems, and poor enabling environments as a basis for quality of resource management. The authors conclude that political security in autocratic resource economies is achieved through the coexistence of political will and triggers, conducive to specifying the length of the planning horizon.Większość badaczy uważa, że państwa bogate w zasoby naturalne mają większą zdolność utrzymywania stabilności politycznej w porównaniu do krajów bez takiego dostępu do wyjątkowych zysków. Jednak niektóre reżimy autokratyczne oparte na rencie surowcowej są jednogłośnie uważane za niestabilne, a ich zdolność do uzyskiwania maksymalnych korzyści nie zawsze przyczynia się do bezpieczeństwa politycznego i gospodarczego podczas wahań cen. Opierając się na założeniu, że zdolność państwa do wydobywania zasobów nakłada na nie pewne obowiązki, zadano pytanie badawcze dotyczące jakości rządzenia jako domniemanego kluczowego czynnika pomiędzy zależnością od zasobów i bezpieczeństwem politycznym państwa a zdolnością do wypełniania przez nie “umowy społecznej.” Tę ostatnią określa się jako realizację decyzji politycznych oraz dostarczanie dóbr publicznych i usług. Jednak jakość rządzenia jest zasadniczo różna w różnych systemach autokratycznych. Wykorzystując studium przypadku i statystyki opisowe, autorzy starają się ukazać kontekst i ustalić, które czynniki wpływają na określenie horyzontu strategii politycznych stosowanych przez autokratyczną władzę podczas wzrostu i spadku cen zasobów. Autorzy potwierdzają, że zależność od zasobów negatywnie wpływa na bezpieczeństwo polityczne w mniejszym stopniu z powodu braku wzrostu gospo- darczego podczas obniżek cen, a bardziej ze względu na walkę elit politycznych o redystrybucję zasobów, brak mechanizmów dyscyplinujących, słabą reprezentację i systemy odpowiedzialności oraz brak sprzyjających warunków będących podstawą dobrego zarządzania zasobami. Autorzy dochodzą do wniosku, że bezpieczeństwo polityczne w autokratycznych gospodarkach zasobowych osiąga się w drodze współistnienia woli politycznej i czynników wpływających na określenie długości horyzontu planowania

    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
