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
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
İzmir-Balıkesir transfer zonunun jeolojik evrimi: Batı Anadolu'daki genişleme tektoniğini yeniden organize eden kıtasal ölçekte bir yapı
No full textBu tez, Ege Genişleme Sistemindeki Menderes Çekirdek Kompleksi ile Kikladlar arasındaki farklı deformasyonu karşılayan ve kabuksal ölçekli bir makaslama zonu olarak tanımlanan İzmir-Balıkesir Transfer Zonu?nun yapısal önemini tanımlamayı amaçlar. Bu çalışmada, İBTZ içindeki Miyosen-Kuvaterner birimleri 1/25.000 ölçeğinde haritalanmış ve birimlerden stratigrafik, yapısal, jeomorfolojik, paleomanyetik ve jeokronolojik veriler elde edilmiştir. Veriler İBTZ?nin transtansiyonal bir makaslama zonu olduğunu ve Neojen öncesi temel kayaları, Neojen volkanosedimanter istifleri ve Pliyo-Kuvaterner birimlerini deforme ettiğini göstermiştir. Yapısal ve kinematik verilere göre, İBTZ?de Geç Senozoyik?te üç deformasyon evresi tanımlanmıştır. Miyosen dönemine karşılık gelen ilk evrede K-G genişleme ve D-B sıkışma sonucunda gelişen doğrultu atımlı faylarca baskındır. Bu evrede KD-GB uzanımlı Miyosen volkanosedimanter havzaların oluşumu gerçekleşmiştir. İkinci evre doğrultu atım-baskın transtansiyondan genişleme-baskın transtansiyona dönüşen tektonizmayla ilişkilidir. Bu evre olasılıkla Erken Pliyosen?deki orta Kiklad çizgiselliğinin aktivitesini yitirmesi ve Menderes çekirdek kompleksinin orta bölümünün en son yüzeylemesiyle eşyaşlıdır. Son evre KB-GD sol yönlü doğrultu atımlı fay, KD-GB sağ yönlü doğrultu atımlı fay ve D-B doğrultulu normal fayların birlikte çalışmasıyla karakteristiktir. Son evrede İBTZ parçalanarak daha dar bir makaslama zonuna dönüşmüştür. Yeni paleomagnetik veriler İBTZ?nin saat ibresinin tersi yönünde rijit bloklar şeklinde rotasyona uğrayan Menderes Çekirdek Kompleksi ve Kikladları ayıran ve zon içinde saatibresi yönünde rotasyonların geliştiği bir makaslama zonu olduğunu göstermektedir. Tüm verilere göre, İBTZ Anadolu levhası altındaki yitim zonundaki bir yırtığın yüzeye yansımış şekli olarak yorumlanabilir. This thesis attempts to expose the structural implication of a crustal scale zone of weakness, the İzmir?Balıkesir transfer zone (İBTZ) which is a recently recognized as strike-slip dominated shear zone that accommodates the differential deformation between the Cycladic and Menderes core complexes within the Aegean Extensional System. Here, I present new stratigraphic, structural, paleomagnetic, geochronologic and kinematic data and 1/25,000 scale mapping of Miocene to Recent rock units within the İBTZ. The results point out that the İBTZ is a transtensional brittle shear zone that deforms the pre-Neogene basement rock units, the early-middle Miocene volcano-sedimentary units and the Plio?Quaternary continental units. The analysis of large-scale structures and fault kinematic data indicate that three different deformation phases prevailed in the İBTZ during the late Cenozoic. The first phase (Phase 1) is characterized by N?S directed extension and E?W contraction that gave way to the development of strike-slip faults with normal components and likely took place during the early (?) to late Miocene. This transtensional phase, forming the volcano-sedimentary basin was overprinted by the second phase (Phase 2) which is characterized by variable extension and contraction directions indicating wrench-to extension-dominated transtension. The structures related to Phase 2 are observed all around the İzmir Bay and indicate a distributed nature of the deformation that probably took place during the early Pliocene, coeval with the end of the activity of the mid-Cycladic lineament and the last exhumation of the central Menderes core complex. The latest deformation phase (Phase 3) is characterized by an association of NW?SE trending left-lateral and NE?SW trending right-lateral strike-slip faults and E?W trending normal faults forming extensional deformation. During Phase 3, the İBTZ evolved from a wider shear zone into a relatively narrow discrete fault zone by the late Pliocene, during which the strike-slip and extensional deformation were completely decoupled from each other. With respect to new paleomagnetic data, İBTZ is a clockwise rotated structural shear zone that separated two counterclockwise rotated rigid blocks; the Menderes and Cycladic complexes, and can be interpreted as the surface reflection of the teared part of the subduction beneath the Anatolian plate
Field evidence for normal fault linkage and relay ramp evolution: the Krkaac Fault Zone, western Anatolia (Turkey)
No full textLinking of normal faults forms at all scales as a relay ramp during growth stages and represents the most efficient way for faults to lengthen during their progressive formation. Here, I study the linking of normal faulting along the active Krkaac Fault Zone within the west Anatolian extensional system to reconstruct fault interaction in time and space using both field- and computer-based data. I find that (i) connecting of the relay zone/ramp occurred with two breaching faults of different generations and that (ii) the propagation was facilitated by the presence of pre-existing structures, inherited from the zmir-Balkesir transfer zone. Hence, the linkage cannot be compared directly to a simple fault growth model. Therefore, I propose a combined scenario of both hangingwall and footwall fault propagation mechanisms that explain the present-day geometry of the composite fault line. The computer-based analyses show that the approximate slip rate is 0.38mm/year during the Quaternary, and a NE-SW-directed extension is mainly responsible for the recent faulting along the Krkaac Fault Zone. The proposed structural scenario also highlights the active fault termination and should be considered in future seismic hazard assessments for the region that includes densely populated settlements
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
