Get PDFThe 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
Get PDF“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
Get PDFWe 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

Investigation of effects of fluorosis on some minerals and hormones in sheep
No full textThis study was carried out to determine the effects of fluorosis on plasma fluor (F), serum calcium (Ca), phosphorus (P), magnesium (Mg), calcitonin (CT), intact parathyroid hormone (iPTH) and vitamin D-3 (Vit D-3) in sheep. A total of 75 Morkaraman sheep, 50 with chronic fluorosis (Fluorotic group) from Tendurek Mountain region (altitude about 2000 m) and 25 without any fluorosis (Control group) from Van (altitude 1700m) were used, aged 3-4 years. Data collected 50 sheeps with chronic fluorosis in the in East Anatolia, Van-Agri, Turkey, were compared with data from 25 without any fluorosis sheeps from the Van region. Plasma F levels were measured with spesific fluride electrode, serum Ca, P and Mg levels were photometrically determined; serum CT and iPTH levels were determined using chemiluminescent immunometric assay, serum Vit D-3 level were analysed with HPLC method. Serum P and Vit D-3 levels were lower in fluorotic group than in control group (p<0.001), while serum CT (p<0.01) and iPTH (p<0.001) levels were higher. The differences for Ca and Mg values were found statistically nonsignificant. The results obtained were after a long term exposure of sheep to high amounts of fluorine and supports occurrence of osteomalatic conditions. In conclusion, clean water should be given to animal and people who live in this region because of irreversible pathological situation occurs after fluorosis develops. Otherwise, Ca, P, Mg and Vit D-3 supplementations has to be given at proper doses to prevent negative effects of fluoride on teeth and bones
