    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

    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

    Ferritin sebagai marker defisiensi besi

    Stunting (WHO) is a nutritional disorder in children based on body length or height that is less than the age of their peers (> -2SD). Diagnosing stunting is quite simple, but our job is to prevent stunting from occurring. Clinical and laboratory data can be used to predict the risk of stunting. The stunting examination laboratory consists of basic examinations: complete blood count, urinalysis, and routine stool. Routine metabolic screening includes random blood glucose, blood gas analysis, lactate, ammonia, ketone bodies, amino acid profiles, and urine organic acids, while additional examinations include culture, iron profile, electrolytes, kidney function, liver function, thyroid hormones, infection exploration, and IgE. Of the many tests, one that can assess the risk of stunting due to iron deficiency is ferritin. Hemoglobin is sensitive for iron deficiency anemia but not for iron deficiency. Iron deficiency can be severe even if the Hb is normal, so the clinician will be late in the diagnosis if they rely on the Hb.Keywords: stunting, iron deficiency, ferritin / Stunting (WHO) adalah kelainan gizi pada anak berdasarkan panjang/tinggi badan kurang dibandingkan umur anak sebayanya (> -2SD). Mendiagnosis stanting cukup sederhana, namun tugas kita adalah mencegah terjadinya stunting. Klinis dan laboratorium dapat digunakan untuk memprediksi resiko stunting. Laboratorium pemeriksaan stunting terdiri dari pemeriksaan dasar: darah lengkap, urinalisis dan feses rutin. Skrining rutin metabolik antara lain glukosa darah sewaktu, analisis gas darah, laktat, ammonia, benda keton, profil asam amino dan asam organik urin, sedangkan pemeriksaan tambahan seperti kultur, profil besi, elektrolit, fungsi ginjal, fungsi hati, hormon tiroid, eksplorasi infeksi, IgE. Dari sekian banyak pemeriksaan salah satu pemeriksaan yang dapat menilai resiko stunting akibat defisiensi besi adalah ferritin. Hemoglobin sensitif untuk anemia defisiensi besi tetapi tidak untuk defisiensi besi. Defisiensi besi bisa parah meskipun Hb normal, sehingga klinisi akan terlambat diagnosis jika berpegangan pada Hb.
