Going Beyond Counting First Authors in Author Co-citation Analysis
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
An Assessment on the Structuring Activity Related with Institutions in Turkey in the Period of Nomadization (1018-1192)
No full textAnadolu 1018-1192 yılları arasında büyük çoğunluğu göçebe hayat yaşayan Türkmenlerin göçüne maruz kaldı. Begler ve sultanlar kurumsal olmayan siyasi yapılar oluştururken, Anadolu’ya göç eden yerleşik Müslüman Türkler ve diğer Müslümanlar siyasi olmayan kurumsal yapılar oluşturdular ve inşa faaliyetlerinde bulundular. Bu kurumsallaşma ve inşa faaliyetlerinin başlaması ve yaygınlaşması bölgelere göre değişmektedir. Danişmendli Begliği’nin hakimiyeti altındaki şehirlerde XI. yüzyılın sonlarında başlamakta, XII. yüzyılın ortalarına kadar birkaç yapı ile öne çıkmakta, XII. yüzyılın ortalarından itibaren görece artmaktadır. Diğer beglikler ve Türkiye Selçukluları’nda ise XII. yüzyılın ortalarına kadar bir yapılaşma görülmezken XII. yüzyılın ikinci yarısından itibaren yapılaşma görülmeye başlamaktadır. Bunda Türkiye Selçukluları ve begliklerin dışarıya karşı ve kendi aralarında verdikleri mücadelenin belirleyici olduğu tahmin edilmektedir. Bu mücadeleler askerileşmeyi artırmış ve gelirlerin büyük kısmının asker olarak istihdam edilen Türkmenlere aktarılmasına sebep olmuş olmalıdır. Göçebelerin özellikle Türkiye’nin batı bölgesine Türkiye Selçukluları hakimiyetindeki bölgeye yığılması Türkiye Selçukluları’nın siyasi ve askeri olarak gücünü artırırken göçebelerin baskısına daha fazla maruz kalmasına, bu da bölgede yapılaşmanın gecikmesine ve seyrekleşmesine neden olmuştur. Artuklu Begliği hakimiyeti altındaki şehirlerde XII. yüzyılın ikinci yarısındaki yapılaşmanın, Türkiye’nin diğer şehirlerine nazaran daha zengin olduğu dikkati çekmektedir. Bunda bu şehirlerdeki yerleşik Müslümanların yoğunluğunun da etkili olduğu tahmin edilmektedir. Yapılaşmanın zamana göre dağılımı siyasi olmayan kurumsal yapıların siyasi yapılardan bağımsız olarak ortaya çıktıklarını göstermektedir. Fakat niteliğinde siyasi yapının gücü ve yerleşiklikle ilişkisinin belirleyici olduğu söylenebilir. Çalışma, 1192 öncesine ait cami, medrese ve sarayların inşa zamanlarının tespiti esasına dayanmaktadır.Anatolia underwent the migration of Turkmens who mostly lived a nomadic life between the years 1018-1192. While lords and sultans created non-institutional political structures the settled Muslim Turks and other Muslims who migrated to Anatolia formed non-political institutional structures and engaged in structuring activities. The beginning and becoming prevalent of this institutionalization and structuring activities change according to the regions. It begins at the end of the XIth century in cities under the Danishmends Beglik, becomes prominent with some structures in the first half of the XIIth century and the concentration is in the second half of the XIIth century. A structuring is not seen in the first half of the XIIth century in other begliks and Seljuks of Turkey and structuring starts in the second half of the XIIth century. It is speculated that the fight put up by the Seljuks and beyliks of Turkey between themselves and outwards is determinative in this. These fights must have increased militarization and caused the transfer of a significant part of the revenues to the Turkmen who were employed as soldiers. While the accumulation of nomads in the western regions of Turkey, in the region under the domination of Seljuks increased the military power of the Seljuks of Turkey it cause it to be more exposed to the pressure of the nomads and this caused a delay and rarefaction in structuring in the region. It attracts attention that the structuring in the cities under the domination of Artuklu Beylik is richer compared to the other cities of Turkey in the second half of the XIIth century. It is speculated that the concentration of Muslims settled in these cities also has an influence on this. The distribution of structuring by time indicates that the non-political institutional structures emerged independent of the political structures. However, it can be said that the power of the political structure and its relation with sedentariness is determinative in its characteristics. The study is based on the determination of the establishment of mosques, madrasahs and palaces before 1192

Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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 textWe 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
