    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” 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

    Literatürde günümüze kadar kırık iyileşmesini etkileyen faktörlerle ilgili birçok çalışma yapılmış ve halen devam eden çalışmalara da bulunmaktadır. Bu çalışmamızda quercetinin kırık iyileşmesi üzerine olan etkisini sıçan femurları üzerinde olusturulan açık kırık modeli ile araştırdık. Ağırlıkları 250–300 gr arasında değişen 80 adet Wistar albino cinsi dişi sıçan çalışmaya dahil edildi. Tüm sıçanlar her grupta sekiz adet olmak üzere on ayrı gruba ayrıldı. Sıçanların son iki grubu (16 adet) ameliyat edilmedi diğer sekiz gruptaki 64 adet sıçanın sağ femuruna açık kırık modeli uygulandı. Birinci (kontrol grubu) ve ikinci (quercetin grubu) grup ameliyat sonrası 2.hafta sonunda sakrifiye edilerek erken histolojik ve radyolojik sonuçları incelendi. Üçüncü (kontrol grubu) ve dördüncü (quercetin grubu) grup ameliyat sonrası 3.hafta sonunda sakrifiye edilerek erken biyomekanik sonuçları incelendi. Beşinci (kontrol grubu) ve altıncı (quercetin grubu) gruplar 4.hafta sonunda sakrifiye edilerek geç histolojik ve radyolojik sonuçları incelendi. Yedinci (kontrol grubu) ve sekizinci (quercetin grubu) grup ameliyat sonrası 6.hafta sonunda sakrifiye edilerek geç biyomekanik sonuçları incelendi. Dokuzuncu ve onuncu grup sıçanlar ile Ameliyat sonrası 3.hafta ve 6.hafta sonunda sakrifiye edilen sıçanlardan alınan kanlarda TAS, TOS ve asit fosfataz çalışıldı. Erken histolojik ve radyolojik sonuçlar incelediğinde quercetin ve kontrol grubu arasında anlamlı fark bulunmadı. Fakat geç histolojik ve radyolojik sonuçlar incelendiğinde quercetinin iyileştirmeyi artırıcı yönde kontrol grubuna göre anlamlı farklılık olduğu görüldü. hem erken hem geç biyomekanik sonuçlarda ise quercetinin iyileştirmeyi artırıcı yönde kontrol grubuna göre anlamlı farklılık olduğu görüldü. Ameliyat edildikten sonra 3.hafta sonunda sakrifiye edilen quercetin ve kontrol grubu sıçanların kanlarında TAS, TOS ve asit fosfataz biyokimyasal belirteçleri arasında anlamlı farklılık izlenmedi. Ancak ameliyat edildikten sonra 6.hafta sonunda sakrifiye edilen quercetin ve kontrol grubu sıçanlarının kanlarında TAS, TOS ve asit fosfataz biyokimyasal belirteçleri arasında anlamlı farklılık izlendi. 3 ve 6 hafta sadece quercetin ile beslenen ameliyat edilmeyen sıçanların kanları arasında TAS ve asit fosfataz arasında anlamlı farklılık izlenmezken, TOS değerinin 6 hafta quercetin verilen grupta anlamlı olarak düşük olduğu görülmüştür. Bu çalışmada quercetinin kırık iyileşmesi erken döneminde çok etkili olmasa da geç dönemde olumlu yönde etkilediği izlendi. Quercetinin kırık iyileşmesini inceleyen başka araştırma literatürde henüz bulunmamaktadır. Quercetinin kırık iyileşmesini etkisini inceleyen başka çalışmalarında yapılması ve daha fazla veriye ihtiyacımız olduğu aşikardır.Many studies have been conducted on the factors that affect the healing of fractures, and there are also many other ongoing studies on this subject. In this study, we examined the effect of quercetin on fracture healing with an open fracture model created on rat femurs. 80 female Wistar albino rats that weigh between 250 and 300 g were included in the study. All rats were divided into ten separate groups, eight in each group. The last two groups of rats (16) were not operated on, and an open fracture model was applied to the right femur of 64 rats in the other eight groups. The first (control group) and second (quercetin group) groups were sacrificed at the end of the second week after the operation and their early histological and radiological results were examined. The third (control group) and fourth (quercetin group) groups were sacrificed at the end of the third week after the operation and their early biomechanical results were examined. The fifth (control group) and sixth (quercetin group) groups were sacrificed at the end of the 4th week and their late histological and radiological results were examined. The seventh (control group) and eighth (quercetin group) groups were sacrificed at the end of the 6th week after the operation and their late biomechanical results were examined. TAS, TOS, and acid phosphatase were carried out on the blood taken from the rats in the ninth and tenth groups and from the rats that were sacrificed at the end of the 3rd and 6th weeks after the operation. When the early histological and radiological results were examined, no significant difference was found between quercetin and control groups. However, when the late histological and radiological results were examined, a significant difference was found in quercetin's contribution to healing compared to the control group. In both early and late biomechanical results, there was a significant difference in quercetin's contribution to healing compared to the control group. There was no significant difference between the biochemical indications of TAS, TOS, and acid phosphatase in the blood of quercetin and control group rats that were sacrificed at the end of the 3rd week after the operation. However, a significant difference was observed between the biochemical indicators of TAS, TOS, and acid phosphatase in the blood of quercetin and control group rats that were sacrificed at the end of the 6th week after the operation. While there was no significant difference between TAS and acid phosphatase in the blood of non-operated rats fed only quercetin for 3 and 6 weeks, TOS value was found to be significantly lower in the group which was given quercetin for 6 weeks. In this study, even though quercetin was not very effective in the early period of fracture healing, it was observed that it had a positive effect in the late period. There is no other study in the literature examining the effect of quercetin on fracture healing. It is clear that other studies examining the effect of quercetin on fracture healing need to be conducted and we need more data on this.Bu araştırma Selçuk Üniversitesi Bilimsel Araştırma Projeleri Koordinatörlüğü tarafından 20122017 proje numarasıyla desteklenmiştir

    Author Under Sail The Imagination of Jack London, 1893-1902

    No full text
    In 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.
