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
Gökova Körfezi depremlerinin kaynak parametreleri ve Rodos-Dalaman bölgesinde tsunami riski
Get PDFThe Gulf of Gökova locates in soutwestern Turkey near the Aegean Sea and surrounded by Datça Peninsula to the south, the island of Kos to the west and Bodrum Peninsula to the north. Active deformation in the region has been observed from widespread seismicity, active normal faulting and tectonically generated topography. In recent and historical times, many destructive earthquakes have occurred in southwestern Turkey. Most of the seismic activity is concentrated along the northern branch of Gökova Fault Zone and it is controlled by E-W trending normal fault system. Intense earthquake activity occurred in Gulf of Gökova in August 2004 and January 2005. Source mechanism solutions and rupture histories for 10 earthquakes, of magnitude Mw ³ 5.0 and shallow focal depth (h < 20 km), which occurred in the region during the period 1986-2005, are used to investigate the geometry of faulting in the region. To obtain source mechanisms and slip distributions on the fault plane, we compared the shapes and amplitudes of long period P- and SH- waveforms recorded in the distance range of 30-90 degrees. The seismograms are formed by the combination of direct (P or SH) and reflected (pP and sP, or sS) phases from a point source embedded in a given velocity structure. Receiver structures are assumed to be homogeneous half-spaces. Seismograms were weighted according to the azimuthal distribution of stations. The solutions were also constrained by P-wave first motion polarities of near-field stations. All the distribution of P-wave first-motion polarities on the equal-area projection of the lower focal hemispheres are consistent with the minimum misfit solutions within a few degrees, with the strikes and dips of the nodal planes. We have also obtained earthquake rupture histories and slip distribution on the fault plane using teleseismic broad-band P waveforms. The rupture process were presented as a spatio temporal slip distribution on a fault plane which was divided into M x N subfaults with length dx and width dy. Then, slip-rate function on each sub fault was described by a series of triangle functions with a rise time. Generally, earthquakes initiates with an earthquake cluster activity and continue for a long time in the gulf. This kind of earthquake generation pattern can carry on by weeks or months decreasing in frequency and in magnitude. The kinematics of the deformation is controlled by normal faults with small strike slip components trending E-W, NE-SW and NW-SE directions. Earthquake source mechanism solutions indicate that normal fault mechanism with a strike-slip component have been observed on the E-W oriented graben and normal fault systems in the Gulf of Gökova and they confirm that extension is in a north - south direction that is in a good agreement with the geology and tectonic structure of the region. T-axes directions obtained from source mechanism solutions demonstrate the NW-SE direction of extension as a result of the convergence between the African plate and the Eurasian plate and the westward movement of the Anatolian block. On the other hand, all earthquakes have generally short source duration and uniform rupture propagation along the dip direction and their focal depths are generally less than 15 km and thus we may suggest that seismogenic thickness in this region is about ~10 km. All these slip distribution results show a uniform circular rupture propagation along the dip direction with a short source duration for earthquakes in Gulf of Gökova . On the other hand, the Gulf of Gökova has a real and major tsunami hazard to the lives and population since it is near the Eastern Mediterranean coast. In this study we have also investigated the tsunami wave propagations to obtain time histories of water surface fluctuations and water particle velocities created by historical 1481 Rhodes earthquakes (M~7.0-7.5) in the Eastern Mediterranean sea using TUNAMI-N2 and AVI-NAMI mathematical models based on the method of Okada (1985). The related parameters for the earthquake are adapted by an analogy of current plate boundaries and earthquake source mechanisms obtained by inversion of teleseismic P- and SH- waveforms. The understanding the faulting geometry, tectonic evolutions and source rupture processes along the active fault zones have significant importance on the tsunami generation. The major and well-known seismic generated tsunamis have occurred in Aegean and Mediterranean Seas and these waves affected the coastal regions since historical times.

Son yıllarda özellikle 2004-2005 tarihleri arasında körfez içerisinde bir çok sayıda orta büyüklükte (Mw³5.0) deprem meydana gelmiştir. Bu çalışmada ters çözüm teknikleri ve telesismik uzaklıklarda kaydedilen P ve SH dalga şekilleri kullanılarak bölgede oluşan güncel depremlerin kaynak mekanizması parametreleri ve fay düzlemi üzerinde meydana getirdikleri kayma dağılımı ve yırtılma süreçleri modelleri elde edilmiştir. En küçük hatalı kaynak mekanizması çözümlerine göre depremler genel olarak D-B doğrultulu normal faylanma mekanizması ile sığ odak derinliklerinde meydana gelmektedirler. Kaynak mekanizması çözümlerinde çok küçük miktarlarda doğrultu atımlı faylanma bileşenleri bulunmaktadır. Telesismik cisim dalgalarının ve yakın alan istasyonların ters çözüm ile modellenmesi sonucu elde edilen kayma dağılımı modelleri ise depremlerin oldukça basit şekilli ve dalım yönünde ilerleyen dairesel kırılmalar ile meydana geldiklerini göstermektedir. Ayrıca, Hellenik Yayı’nın doğu uzanımı üzerinde yer alan Rodos adası ve çevresinde tarihsel dönem içerisinde meydana gelen ve tsunami (depreşim) dalgalarına neden olduğu rapor edilen birçok sayıda deprem bulunmaktadır. 1481 yılında meydana gelen tarihsel depremler için sığ su dalgası teorisine dayalı yöntemlerle ve GEBCO-BODC batimetri verisi ile tsunami dalga simülasyonları yapılmıştır. Simülasyon sonuçları bu bölgede meydana gelen bir depremin daha çok episantıra yakın bölgelerde örneğin Rodos adası ve çevresinde ve Gökova Körfezi - Fethiye kıyılarında etkili tsunami dalgalarına neden olduğunu göstermektedir.

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
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
